Traffic Problem

Interstate 80, seen here in Berkeley, California, is a freeway with many lanes and heavy traffic. Traffic on roads may consist of pedestrians, ridden or herded animals, vehicles, streetcars and other conveyances, either singly or together, while using the public way for purposes of travel. Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections.Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck); other vehicle (e.g., moped, bicycle); and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate. Organization typically produces a better combination of travel safety and efficiency.Events which disrupt the flow and may cause traffic to degenerate into a disorganized mess include: road construction, collisions and debris in the roadway. On particularly busy freeways, a minor disruption may persist in a phenomenon known as traffic waves. A complete breakdown of organization may result in traffic congestion andgridlock. Simulations of organized traffic frequently involve queuing theory, stochastic processes and equations of mathematical physics applied totraffic flow. Traffic in English is taken from the Arabic word taraffaqa, which means to walk along slowly together.Contents1 Rules of the road 1.1 Directionality 1.2 Traffic regulations 2 Organized traffic 2.1 Priority (right of way) 2.1.1 Uncontrolled traffic 2.2 Turning 2.2.1 Intersections 2.2.2 P edestrian crossings 2.3 Level crossings 2.4 Speed limits 2.5 Overtaking 2.5.1 Lanes 2.6 One-way roadways 2.6.1 High-speed roads 2.6.2 One-way streets 3 Congested traffic 3.1 Rush hour 4 Congestion mitigation 4.1 Rush hour policies 4.2 Pre-emption 4.3 Intelligent transportation systems 5 Future of congestion mitigation 6 See also 7 References 8 External links 9 Further reading Rules of the road[edit]Traffic controller in Chicago, Michigan AvenueTraffic control in Rome, Italy. This traffic control podium can retract back to road level when not in use. Rules of the road and driving etiquette are the general practices and procedures that road users are required to follow. These rules usually apply to all road users, though they are of special importance to motorists and cyclists. These rules govern interactions between vehicles and with pedestrians. The basic traffic rules are defined by aninternational treaty under the authority of the United Nations, the 1968 Vienna Convention on Road Traffic.Not all countries are signatory to the convention and, even among signatories, local variations in practice may be found. There are also unwritten local rules of the road, which are generally understood by local drivers. As a general rule, drivers are  expected to avoid a collision with another vehicle and pedestrians, regardless of whether or not the applicable rules of the road allow them to be where they happen to be.In addition to the rules applicable by default, traffic signs and traffic lights must be obeyed, and instructions may be given by a police officer, either routinely (on a busy crossing instead of traffic lights) or as road traffic control around a construction zone, accident, or other road disruption. These rules should be distinguished from the mechanical procedures required to operate one's vehicle. Seedriving. DirectionalityMain articles: Bidirectional traffic and right- and left-hand traffic Traffic going in opposite directions should be separated in s uch a way that they do not block each other's way. The most basic rule is whether to use the left or right side of the road. Traffic regulationsSee also: Category:Rules of the roadIn many countries, the rules of the road are codified, setting out the legal requirements and punishments for breaking them. In the United Kingdom, the rules are set out in the Highway Code, which includes obligations but also advice on how to drive sensibly and safely. In the United States, traffic laws are regulated by the states and municipalities through their respective traffic codes. Most of these are based at least in part on the Uniform Vehicle Code, but there are variations from state to state. In states such as Florida, traffic law and criminal law are separate, therefore, unless someone flees a scene of an accident, commits vehicular homicide or manslaughter, they are only guilty of a minor traffic offense. However, states such as South Carolina have completely criminalized their traffic law, so , for example, you are guilty of a misdemeanor simply for travelling 5 miles over the speed limit.Organized trafficPriority (right of way)[edit] See also: Right-of-way (disambiguation) Vehicles often come into conflict with other vehicles and pedestrians because their intended courses of travel intersect, and thus interfere with each other's routes. The general principle that establishes who has the right to  go first is called â€Å"right of way†, or â€Å"priority†. It establishes who has the right to use the conflicting part of the road and who has to wait until the other does so. Signs, signals, markings and other features are often used to make priority explicit. Some signs, such as the stop sign, are nearly universal.When there are no signs or markings, different rules are observed depending on the location. These default priority rules differ between countries, and may even vary within countries. Trends toward uniformity are exemplified at an international lev el by the Vienna Convention on Road Signs and Signals, which prescribes standardized traffic control devices (signs, signals, and markings) for establishing the right of way where necessary. Crosswalks (or pedestrian crossings) are common in populated areas, and may indicate that pedestrians have priority over vehicular traffic. In most modern cities, the traffic signal is used to establish the right of way on the busy roads.Its primary purpose is to give each road a duration of time in which its traffic may use the intersection in an organized way. The intervals of time assigned for each road may be adjusted to take into account factors such as difference in volume of traffic, the needs of pedestrians, or other traffic signals. Pedestrian crossings may be located near other traffic control devices; if they are not also regulated in some way, vehicles must give priority to them when in use. Traffic on a public road usually has priority over other traffic such as traffic emerging fro m private access; rail crossings and drawbridgesare typical exceptions.Uncontrolled trafficUncontrolled traffic comes in the absence of lane markings and traffic control signals. On roads without marked lanes, drivers tend to keep to the appropriate side if the road is wide enough. Drivers frequently overtake others. Obstructions are common. Intersections have no signals or signage, and a particular road at a busy intersection may be dominant – that is, its traffic flows – until a break in traffic, at which time the dominance shifts to the other road where vehicles are queued. At the intersection of two perpendicular roads, a traffic jam may result if four vehicles face each other side-on.Traffic ProblemsTraffic congestion in many cities around the world is severe. One possible solution to this problem is to impose heavy taxes on cardrivers and use this money to make public transport better. This essay will discuss the benefits and drawbacks of such a measure. One of t he first benefits of such a measure is that the heavy taxes would discourage car owners from using their cars because it would become very expensive to drive. This would mean that they would begin to make use of public transport instead, thus reducing traffic problems and pollution as well. Another benefit would be that much more use would be made of public transport if it was improved. It is often the case that public transport in cities is very poor.For example, we often see old buses and trains that people would rather not use. High taxes would generate enough money to make the necessary changes. Nevertheless, there are drawbacks to such a solution. First and foremost, this would be a heavy burden on the car drivers. At present, taxes are already high for a lot of people, and so further taxes would only mean less money at the end of the month for most people who may have no choice but to drive every day. In addition, this type of tax would likely be set at a fixed amount. This wo uld mean that it would hit those with less money harder, whilst the rich could likely afford it. It is therefore not a fair tax. To conclude, this solution is worth considering to improve the current situation, but there are advantages and disadvantages of introducing such a policy.Traffic managementCreating a travel planOne of the most effective ways to ease traffic congestion at schools is to reduce the number of cars coming and going from your school. Boards of trustees can encourage students and staff to walk, cycle, take public transport, ride the school bus, participate in a walking school bus or car pool to school. Another way to manage traffic is to prepare a travel plan for traffic movement in and around the school, parking and pedestrians. Developing a travel plan with your community will get people thinking about alternative options for getting to and from school.Complete the Traffic management checklist [Word; 92kb] before preparing the travel plan. Guidance on developin g a travel plan is available at: NZ Transport Agency – provides a guide for developing school travel plans and organising a walking school bus Safe Kids New Zealand – has resources for educators about keeping kids safe including child pedestrian safety NZPolice – has a School Road SafetyEducation programme which teaches young people road safety skills. Check with your local council as they often have information about safety on the road. For example, Auckland Transport has information about road safety, walking and cycling, and encouraging students to use alternative transportation; Christchurch City Council has a programme called Safe Routes to Schools which investigates road safety issues in school communities and develops strategies to encourage safe and active travel to school. Improving traffic movement through the schoolA good system for dropping off and picking up students will help manage traffic around and through the school. The system will depend upon the school, for example, if the school is located in an urban area with busy streets, coordinating traffic in and out of the school during peak times is critical, otherwise drivers are tempted to park illegally in the surrounding neighbourhood. Illegal practices include double parking and parking on yellow lines, across driveways, and near crossings. Many drivers justify this behaviour because they are only parked for a short time and they usually stay with the car. However, this practice is irritating for neighbours and unsafe for other road users. Traffic movement checklistA good traffic system through the school includes: car traffic flows in a clearly marked oneway direction pedestrian access points located separately from car access points the bus bay is separated from car and pedestrian access points an off-street drop-off/pick-up zone staff station at key points to manage traffic flow car access separate from the car park. If your school does not have land available to creat e an on-site drop-off/pick-up zone, you can contact the local council and ask for a dedicated kerbside access area on an adjacent street, if there are traffic issues. An example of an efficient traffic systemOther ideas for improving the flow of traffic include: staggering start and finish times for different year groups having staff to manage drop-offs and pick-ups at peak times will encourage  cars to move along and not park. Paying for work to improve traffic systemsBoards can use Five Year Agreement (5YA) funding for work to improve traffic systems on their school site. Work needs to be planned in the 10 Year Property Plan (10YPP), and budgeted within the available 5YA funding. Car parkingBoards of trustees should have a parking policy about who can use the car parks on the school site. The policy will usually provide for staff and some visitors' car parks. It is likely that there are not enough parks for students at a secondary school, which can create congestion in the neigh bourhood. Schools can to talk to their local council, including parking enforcement officers familiar with the area, for ideas about managing the school’s parking issues. New car parksThe need for new or upgraded car parks may be triggered by new teaching spaces for roll growth space. In the new teaching spaces budget, boards are given a site works allowance for each roll growth classroom to pay for new car parks. The Ministry does not have a policy on the number of car parks schools should have, but local councils may have requirements in their District Plans that kick in when the school applies for building consent for a roll growth room or other type of project.The council may require a traffic impact assessment. If the costs of new parks exceed the site works allowance, either because of the number required by the council or their cost, then additional funding will be considered. If the board wants car parks in excess of the council requirement, this must be funded throug h 5YA.Special events – parkingSpecial events can cause parking problems. Ideas to manage these problems include: encouraging people to walk, car pool or use public transport opening up some of the grounds, such as playing fields or tennis courts, to provide extra parking arranging the use of nearby parking facilities  arranging the use of remote parking facilities and provide shuttles to the event employing staff to direct traffic.Traffic impact assessments When a school applies for a building consent for a new building project the council may ask for a traffic impact assessment. The council will want to know if the proposed project will generate extra traffic and a need for additional parking, and how the school intends to manage the changes in traffic or parking. For larger projects, the council may require a professionally-prepared traffic impact assessment with an engineer’s report. Ask your council for names of companies who carry out these assessments or search the internet for traffic assessment consultants.Traffic requirements vary depending on what the council has in their district plan. Some councils may require more parking spaces to be provided and some may have traffic requirements depending on the educational use, breaking them down by primary, secondary and tertiary institutions. Other councils may have more general requirements. Schools will have to convince the council they are managing parking and traffic flows – having a good travel plan and traffic system will help. Boards should ensure their school community are not causing traffic and parking problems for neighbours because those neighbours may object to a school’s building consent application. Traffic management checklistThe following checklist will be helpful: before starting the travel plan for use by the professional consultant hired to prepare a traffic impact assessment – the assessment should address these issues as a minimum and providing this information will reduce the time and therefore cost of a consultant.

Conclusion and recommendation Essay

Based on the results of the focus group discussion and the interview, Web 2. 0 applications being utilized for educational purposes are seen to have a very good potential in being integrated into educational processes for teaching and learning. Reflective of the first objective, it has been seen that there is a positive outlook with regards to Web 2. 0 applications from students and how the communicate. In addition, it is seen that educational processes would from time to time inculcate particular. Web 2. 0 applications and replacing conventional educational tools with newer and more technologically adept Web 2.0 applications in order for educators to be more effective in communicating with students. With respect to the sixth objective of this study, educators are keen to note that Web 2. 0 applications have the potential for being used as a tool for educational purposes. Educators on one hand furthered this conclusion because of their openness to the concept of including Web 2. 0 applications in their curriculum, utilizing its capabilities in effectively transferring knowledge to their students and more importantly communicating with them. In answering objectives two and three, educators themselves indicated that they are able to already utilize Web 2. 0 applications for providing administrative information to their students and they have indicated that Web 2. 0 applications being used as educational tools already exists and is being utilized by other educators. They are able to go with the flow of innovation as students are getting more and more adept with the use of such internet tools that they are able to identify with this and use this to the teacher’s advantage. The educators have identified that Web 2. 0 applications such as Blogs, Wikis, and other social networking tools have the potential to be used as teaching tools. Being able to use such a tool would not only make their teaching efforts easier but more importantly more effective in bringing information to their students. Coming from the aim of the study particularly to identify how Web 2. 0 technologies can be applied to Higher education, it is apparent that due to the inputs coming from both the student body and educators and because of extant literature there is an apparent improvement in the use of Information Technology in higher education. With the current use of Web 2. 0 technologies such as that of Flickr, Wikis and Myspace by both students and educators in communicating and teaching learning, Web 2. 0 technologies in the future will most certainly be integrated into higher education. This is due to the cultural changes that are observed within educators and students as how they perceive Web 2. 0 technologies and their effect on higher education. This is already evident as students currently utilize such Web 2. 0 applications in communicating with their peers for educational purposes. The next phase would be to utilize such tools more effectively and efficiently by the educators themselves in communicating with their students. On the other hand, because of such an increase in utilization, it would be constructive for this area of educational research if there are additional in-depth studies pertaining to Web 2. 0 technologies and how they affect higher education. In order to further explain and expound on this body of knowledge, it is recommended that a considerable number of focus groups be added into the study. This would yield a more accurate and diverse collation of answers. This would then be used in acquiring more information and validating the results of this study. In addition to the methodology, there should be an inclusion of several interviews to be conducted on other areas particularly other educational classes and universities so as to identify the relationship of geography with Web learning. In addition to this, it would be useful to identify if there is a relationship between racial background and web learning, is there a trait that controls the preferences of various races utilize web 2. 0 applications and if there is a relationship with race. Lastly, In addition to what was mentioned above, it would prove crucial if there is further study with regards to other countries and how they are able to utilize Web 2. 0 applications in their pursuit for better education. This would be able to provide the research with a better comparison particular to the effects of countries with respect to Web 2. 0 applications and Web learning.

Sustainability framework on Apple and Samsung Essay

Sustainability framework on Apple and Samsung - Essay Example Recognition of organizations embracing environment sustainable frameworks is because climate change has become a significant issue in the society (Hart, 1997). A sustainable framework consists of Clean technology, sustainability vision, Pollution prevention and Product Stewardship (Hart, 1997). This paper will analyze two companies in the same industry in regards to their efforts to reduce environmental pollution. The analysis will be on Apple and Samsung companies. In addition, the paper will compare the sustainability framework suggested by Hart to the framework implemented by these two companies. Samsung has been viewed as a leader in this particular industry. Since the creation of Samsung, a lot has been put in place to reduce environmental pollution. Samsung is a telecommunications company with a variety of products on its brand. Its major products are mobile phones, computers and other electronics. The company has a significant global market with target market across the globe. 70 % of all nations across the globe boast of at least one major Samsung outlet (Magureanu, 2013). For this reason, the production level of the business entity is significant considering the level of demand on its products. With a large production level, the levels of emissions in the practice are also high. For this reason, this organization has set strategies to reduce their emissions to the environment. This is the ability of an organization to use technology that is environmental friendly. In addition, an organization should be able to develop approaches to technology that are environmental friendly. Samsung is developing technology that considers suitability to the environment (Magureanu, 2013). Comparing old and new products by Samsung, there are significant differences in the hazardous nature of the product. In an argument by Hart (1997) Samsung products are less radioactive even when

Management and leadership Research Paper Example | Topics and Well Written Essays - 500 words

Management and leadership - Research Paper Example Another difference between management and leadership is related to their approach and perspectives. At Boeing, managers always think incrementally and they do everything in accordance with the company’s policy, whereas leaders think radically and they follow their own initiations in the benefit of the company. The Boeing Company hires managers based on their managerial as well as leadership skills. The company believes that a good manager is one who can motivate and lead the employees effectively by setting his/her own example. Leadership is one of the main elements of Boeing’s culture. It has its roots in every department as all managers lead the employees towards increased performance and productivity. Rampur (2010) states, â€Å"In the corporate world, leadership is undoubtedly the most important action that has to be considered if you want to get the work done collectively†. Every department of Boeing works in partnership with the Boeing Leadership Center that works towards ensuring on-the-job successes by providing leadership development opportunities to the managers of all departments. Managers working at Boeing not only manage and control their employees according to the company’s employee management policy but also help them achieve their tasks in an appropriate manner. Boeing’s senior management support matrix structure and provide clear direction to the employees. They possess all qualities of good leaders, such as, assertiveness, visionary outlook, and skills to influence others. The core essence of a true leader is to improve organizational processes by motivating and influencing the employees. Every department of the Boeing Company strives to improve at all levels and that is not possible if the managers do not possess leadership skills. Therefore, we can say that although the concepts of management and leadership have some differences but every manager working at Boeing possesses both managerial and leadership skills to ensure

Recommendations Essay Example | Topics and Well Written Essays - 500 words - 1

Recommendations - Essay Example 1. The restaurant needs to introduce new initiatives of employees’ health and wellbeing programs to reduce their health problems. Exhaustion is found to be the main cause for their lack of enthusiasm which is reflected in their level of service at the end of the day. A separate small place should be allotted to them to take short breaks to relax and reinforce their energy. Constant communication and constructive engagement with employees significantly enhances morale and commitment to work (MacLeod & Clarke, 2010). Management should involve employees in discussions on how to improve work environment so that they are happy. 2. The management needs to recruit more people to not only maintain its reputation for excellent customer service but it would also relieve pressure from the existing staff. The employees were unanimous in the view that more people are required to meet the rush of the clients. The HR people therefore should create a pool of human resource who can be given part-time work during the rush time. This would help the permanent staff to recover from the highly stressing work of serving many people in short time and with efficiency. 3. Workers need to be motivated through incentives and fringe benefits like complementary weekly family meal at Chipotle or company sponsored family vacation on weekends. It could be a once a month affair based on work performance. This would motivate workers for higher performance (Fisher, 2005). At the same time, it would give them an opportunity to spend quality time with family. The long hours and workplace stress have adverse impact on the work-life balance, creating dissatisfaction amongst the staff. This initiative would boost their morale. 4. The company must provide the workforce with new opportunities of enhancing their skills and knowledge. In-house trainings on skill development and options for partial or full funding of cost for pursuing

Jeffersonian Era Essay Example | Topics and Well Written Essays - 1000 words

Jeffersonian Era - Essay Example Jefferson argued that the Court was a creation of the Constitution and to give it the power of judicial review would make "its discretion and not the Constitution the measure of its powers." He argued that when the federal government assumed a power not granted to it by the Constitution, each state, as a party to the constitutional compact, had a right to declare the law unconstitutional (see State Sovereignty and States' Rights). He also believed that each branch of the federal government had a coordinate right to resolve questions of constitutionality," ("Thomas Jefferson", p.1). This act taken, with the assistance of fellow politician James Madison, would serve to show Jefferson's view on judicial law, as well as the rights of states. The notion of the states being able to declare a law unconstitutional, if the federal government creates it through such means as assuming power not held within the Constitution, reaches into present day governing in the sense of the 'checks and balances system,' that exists in the present structure of the political system in all facets. Keeping with the notion that all branches of government is on equal footing and as such have the opportunity to answer issues having to do with how a decision, or decisions, fall into the overall framework of the constitutional document itself. As President, "The President's greatest triumph - and his greatest defeat - came in foreign affairs. Spain's cession of Louisiana and the port of New Orleans to France in 1800 posed a serious threat to American security, especially to the aspirations of the West. Jefferson skillfully negotiated this crisis. With the Louisiana Purchase (1803), America gained an uncharted domain of some 800,000 square miles, doubling its size, for $11,250,000. Even before the treaty was signed, Jefferson planned an expedition to explore this country. The Lewis and Clark expedition, like the Louisiana Purchase, was a spectacular consummation of Jefferson's western vision," ("Thomas Jefferson", p.1). With international relations being a pillar of any President's ability to govern skillfully, the acquisition of the Louisiana territory would bode well for Jefferson in this regard. In the current landscape of political campaigning and governance, current politicians promise numerous things. One of those such promises are that of the reduction in taxes for certain portions of the individual citizenry. As a way to revamp the tax system of the time, "When Thomas Jefferson was elected President in 1802, direct taxes were abolished and for the next 10 years there were no internal revenue taxes other than excises," ("Fact Sheets: Taxes", p.1). As taxes are the means of paying for necessary governmental services, there would be other options taken in response to the extraction of internal revenue taxes. Those being, "To raise money for the War of 1812, Congress imposed additional excise taxes, raised certain customs duties, and raised money by issuing Treasury notes. In 1817 Congress repealed these taxes, and for the next 44 years the Federal

Human Rights in International Law Essay Example | Topics and Well Written Essays - 2000 words

Human Rights in International Law - Essay Example Other than these methods, other international human rights instruments also exist that are not legally binding but have an effect on the implementation, understanding and development of international human rights laws. These sources of law have been recognised to have a political obligation1. International human rights laws are enforceable on the domestic, regional and international levels. Any states that are involved in human rights treaties undertake a voluntary obligation to respect the rights recognised in the respective treaties. Furthermore, it is the duty of the state to ensure compliance of domestic laws with the conditions laid down in treaties so that domestic and international law is compatible. Although the primary mechanism of human rights protection and the ensuing legal framework are mostly domestic in nature but the bereaved party may resort to regional or international legal mechanisms to redress concerns. Alternatively, regional or international legal mechanisms ma y enforce themselves on domestic situations in order to deal with human rights abuses. Human rights are protected internationally through the use of two parallel legal mechanisms namely the international human rights laws and the international humanitarian laws. ... For general cases, human rights are taken to regulate the relationship existing between individuals and the state within the context of an ordinary life. In contrast, humanitarian laws are taken to regulate the relationship between a belligerent state and any parties it comes into contact with. These parties could be hostile or neutral when seen in the context of an armed conflict2. This paper will concern itself with the implementation of human rights laws alone on the domestic, regional and international levels. 2. International Law on Human Rights In the post World War Two scenario, the Universal Declaration of Human Rights is the watershed of international human rights law. The United Nations General Assembly adopted this declaration in 1948 and can be seen as a reaction to the experiences of the Second World War. In itself, this declaration is the first global expression of rights that all human beings are entitled to3. The importance of this declaration stems from the fact that its articles have been used subsequently in international treaties, national constitutions, domestic laws and regional human rights instruments. The declaration is not a treaty in itself but has been adopted explicitly in order to define the words â€Å"human rights† and â€Å"fundamental freedoms† that are listed in the United Nations Charter. In turn, the United Nations Charter is binding on all member states and so the Universal Declaration on Human Rights is a fundamental constitutive document for the United Nations. A large body of international lawyers holds that the Declaration is part of customary international law. This position implies that the Declaration is an

Philosophy of Assessment Term Paper Example | Topics and Well Written Essays - 1250 words

Philosophy of Assessment - Term Paper Example This essay considers my personal philosophy of assessment. One of the primary considerations I recognize in terms of assessment is developing a means of judging student participation and effort throughout the marking periods and course. One of the primary challenges I had when originally considering assessment was the nature of developing assessment strategies that are student specific, or measure objective standards of comprehension. While ideally classrooms are constituted by students of the same level of achievement, in reality this is not always the case. Early in my teaching career I recognized that I would have to make the difficult decision of requiring all students to achieve the same level of achievement. From this foundational level I then began to design assessment strategies that required students to achieve an objective standard of accomplishment. In these regards, I have been greatly influenced by constructivist theory of assessment, specifically a text Understanding by Design. This text contends that assessment should be designed from a top-down structure with the end goal in mind. Working from this theory, each semester I considered the ultimate objective for the course and then worked back from that in developing assessment strategies that would work as standards bearers for the marking period. Still, I recognize that this approach to assessment should only be used to construct a general approach to curriculum development. As is later demonstrated, the most effective instruction and assessment will consider the learner’s background knowledge and phenomenological grasp of the learning material in developing dynamic and multi-varied assessment mechanisms. In addition to these constructivist approaches to assessment, I have become more directly acquainted with direct methods of assessment. It’s indicated that one of the primary such means of demonstrating direct assessment strategies is through the teacher’s active involvement in student learning. In these regards, â€Å"the teacher a) presents information, b) develops concepts through lecture, c) requires students to recite or respond to questions, d) provides feedback and reteaching as necessary† (Payne 63). In terms of my own assessment strategies, I implement direct methods in a variety of ways. After determining the end of course objective I would then break down the marking period into manageable units (chapters). Within each of these units (chapters) there would be a final exam and quizzes. The quizzes were implemented in large part as a means of motivating students to remain consistent with scholastic work throughout the chapter. In these regards, oftentimes I approached quiz grades with a more lenient approach than I did the chapter tests. The student quiz scores also functioned to aid me in identifying areas of student progress that are more in need of attention. Indeed, student quiz assessment was a learning process for the students as well, giving them an early idea of elements of the text that they must further study. With the final exam then students had to demonstrate their mastery of the material. Rather than functioning as a learning aid, the final exam existed solely for the purpose of measuring the student’s achievement in relation to the objective progress they made within the specific unit. Through research I have discovered a

Final Film Critique Research Paper Example | Topics and Well Written Essays - 2000 words - 1

Final Film Critique - Research Paper Example The movie has gained worldwide recognition due to it being able to address a large audience on a global scale that has been able to relate with every aspect of it. This paper thus helps to provide an insight into the technical factors of the movie including things like its acting, storyline, cinematography as well as style and direction, and how the story of Juno managed to engage people all over the world and help it become worthy of receiving international accolades. Juno the film has a very basic story line as well as concept attached to the tale; it is about a young girl trying to explore the nooks and crannies of intimacy and relationships without understanding the implications that might arise along with the same. The film has been directed in a very concise manner making use of pencil stylized ‘rotoscoped’ images right from the credits in the beginning, making use of animation in order to help the audience understand the maturity level of the girl and the kind of colourful life that she always wanted to live for herself. This entire sequence took a period of seven to eight months to be mastered as each and every shot that follows Juno on her way to the medical pharmacy was taken in short screenings. The set design is incredible, assisting in providing the film with a touch of wonder. The story has been told through the eyes of Juno herself, as she takes the audience along on her woven tale of how she ended up having sexual relations with her classmate whom she did not have any feelings for. The film thus helps teenagers to explore the kind of curiosity that reigns within them, and how the same should be understood not by simply jumping in and trying things out with friends, but by reading about things and comprehending the facts about life from one’s parents first. It helps children and young adults to understand how friends might not be the best option when it comes to understanding such information about pregnancy and intercourse. T hese aspects of life are crucial to one’s existence and they must be understood well by every individual so that he is able to make his own decisions without falling into trouble or having unplanned circumstances crop up in his life. (Sciretta, Peter) Thus, the film achieved mass appeal because of the story telling as well as how the girl managed to learn her lesson without panicking much about the situation. The various characters within the movie have been portrayed in a very interesting manner. The director has taken his time to choose the main protagonists and provide them with a different twist. Juno is a young teenage girl who comes off a little strong on the first meeting with everyone. Full of sarcasm, she helps to put an indie spin on the movie and gives a very intense performance with her dominating nature and need to control everything that might not even be in her reach. However, she understands where she went wrong by getting pregnant but decides to bring about a change in a couple’s life with the help of her baby who she is willing to give up in order to make someone else happy. There was a vast amount of dramatisation in the film played by the other characters, namely Juno’s parents which helped to calm the situation by making her understand what she had gone through, and helping her come out with a solution rather than screaming at her and making her feel the pain of the

Enhancing the Quality of Services and Processes through Strategic Essay

Enhancing the Quality of Services and Processes through Strategic Management - Essay Example The paper tells that the contemporary hospital presents a complex inter-relationship of responsibilities in addition to objectives that need to be balanced to enhance service delivery. Hospital executives constantly focus on internal aspects such as recruitment, acquisition of facilities and equipments as well as provision of healthcare to patients. The Arnold Palmer Hospital is evocative of a scenario whereby top management mainly focuses on patient satisfaction as an end in itself. Patients can be awarded valuable gifts of up to $200 by the hospital employees in case they complain reasonably. As much as it is necessary to apply a patient focused approach to management of the hospital, it is also necessary to take in to consideration the external factors that influence the strategic position as well as the day to day operations of the facility. The hospital managers need to focus on satisfying the needs of employees, patients and other stakeholders who represent diverse interests. S trategic management involves designing, implementing and evaluating managerial decisions so as to be able to accomplish an organization’s long term objectives. It also involves systematic analysis and evaluation of internal and external factors so as to be able to make decisions for the future of the organization. Liebeskind views strategic management as a process whereby managers decide on the mission, vision and objectives which they would like to be achieved over a specified time limit. They develop policies and plans to be followed by employees so as to achieve the mission and objectives. After developing plans, they provide resources that facilitate the implementation of policies and after a specified time, they evaluate whether the goals have been accomplished. Mission statements help managers to set the company direction (Collis & Montgomery 2001). Various theories have been put forward by scholars regarding what strategic management entails. Mintzberg’s theory helps managers to interpret the process of strategic planning and be able to plan even when internal or external factors influence the accomplishment of daily activities. Arnold Palmer Hospital’s management can accomplish its strategic objectives if Mintzberg’s approach is adopted (Mintzberg, 1990). The management of this hospital needs to design, plan and position the hospitals operations in consideration of the future. The designing process according to Mintzberg involves with strategy development whereby the management evaluates the strengths and weaknesses of the institution against the opportunities and threats which are among the external factors affecting its efficiency. Based on the result, the management is able to formulate a strategy which addresses the shortcomings while trying to maintain equilibrium between the external factors and organizational performance. The organizational strategy needs to be understood and implemented by all staff members while on the other hand. Flexibility in strategy is important to ensure that the organization maintains competitiveness in the constantly changing operating environment (Mintzberg, 1990). Planning involves formulating a strategy with a time line, goals and objectives, which are stated and formulated to help achieve the organizational objectives. A plan will provide the hospital’s management with direction through clearly stated objectives. Planning is a continuous process as variables keep changing hence the need for management to be ready for changes throughout the organization’

Boasting a total of 70 Billion assets and earning an all-time high of 20 Billion of sales the year 2011, this year, they aim to earn higher; 30 Billion of sales, so to provide Filipinos a chance to experience a dynamic living in a vibrant master planned city. What gives Filinvest Alabang Inc. an edge compared to other Real Estate developer? Simple, they bounded their project in a very good location, wherein the city is connected to 5 major road points; giving them maximum exposure to businessman, commuters and even prospect buyers. In terms of their recruitment routine, applicants undergo a series of observations, interviews and training so to identify if they are well qualified for the job and somehow has the ability to achieve the given job description. With this type of assessment, Filinvest Alabang Incorporated accepts highly qualified sellers to help the company achieve its target mark for this year, making sure that the ones they accept will be able to function really well. Weakness Given the amount of time that the recruitment process takes to finally hire employees, there is a possibility that they might miss out other highly qualified applicants due to the long process of interviews and series of training. Some applicants might lose their interest given the time that the training process eats. And due loss of interest of applicants, there’s a blink of probability that other Real Estate companies will snatch the chance of getting those type employees and definitely that gives Filinvest a slight margin of disadvantage. Opportunities With a well renowned name in the industry of Real Estate, that puts Filinvest Alabang Inc. in a good position as a top of mind priority for businessmen and job applicants. Knowing that selling real estate requires a huge workforce, evidently the corporation is in search of many inspiring job applicants who want to earn big money. And Filinvest Alabang give those kinds of opportunities to unemployed individuals who wants to make a living. They actually have a very flexible standard when they hire applicants, because they can’t throw away the fact that they need an individual with great talent, given that he/she wasn’t able to meet one of the required standards to be hired be swatted away. Threats Obviously, Filinvest ALabang Inc. is not only the renowned RealEstate developer here in the Philippines. Other top competitors Ayala Land and SMDC for example use different kind of strategies to lure prospect buyers to buy their luxurious properties and of course, they have a different style of training used to hone the skills of their employees. With the presence of other top real estate companies, that makes the stakes of hiring highly qualified employees divided among those corporations. VII.Alternative courses of action Detailed Background Check. ( Past Employment ) To make the process of recruitment shorter, the Human Resource management could use a background check with regards to the individual’s past employments (if available), whether he/she has background working on a sales team which will help clarify points if the individual is capable of being part of the Filinvest Alabang sales team. Putting a little bit of emphasis on the applicant’s background would help shorten the period of training knowing that he/she is capable of being a seller. That will definitely help cut the expenses that the company supply for training and seminars as part of the training program Experience Experience is definitely a plus when you apply for a job. And for Human Resource managers, an applicant with plenty of experience makes the job easier. Knowing that the individual is already knowledgeable of the job description and knows what are the functions of being a seller, those type of statistics may lead to fewer training and interviews. But the management definitely should not rest easier; they should conduct a detailed background check regarding the past performance of the applicant like consulting the previous company where he/she worked for about how he/she dealt with the stress of the job and etc. VIII.Recommendation †¢Conduct seminars for improvement of customer relationship and as well as the employee to employee relationship. †¢Conduct monthly meeting to be aware of the status of each organization of the corporation. †¢Get feedback from customer to distinguish the quality and satisfaction of service and products the Filinvest offers. IX.Action plan / time constraint The Human Resource management could make a proposal to be sent to the higher level management regarding the issue of slow recruitment process and suggest that they should focus more on analyzing and looking briefly at the individual’s experience by conducting background check so to lessen the time that the training and interviews are taking. That way, the recruitment process would somehow speed up, and in case they get better results, they should continue to do it or perhaps improve the system more. And in case that the strategy is not working out, they should try to evaluate on what seems to be out of sync and once they were able to point out the problem, they should be able to come up with good solutions to the problem. X.Conclusion The researcher recommends that the management of Filinvest Alabang Incorporated should speed up the process of hiring highly qualified employees without sacrificing their thoroughness in selecting the best among the job applicants. They could focus more on looking briefly at the resume of the employee and perhaps, they could perform through background check on the individual to ensure that they are qualified for the job. That way, they could cut the cost allotted for many sessions of trainings and undying interviews.

A Room with a View: Chapter by Chapter Analysis

A Room with a View: Chapter by Chapter Analysis Opening a Window A Room with a View by E.D. Forster explores the struggle between the expectations of a conventional lady of the British upper class and pursuing the heart. Miss Lucy Honeychurch must choose between class concerns and personal desires. Honeychurch is a respectable young lady from a well-known family. She travels with Miss Charlotte Bartlett to Italy at the turn of the century. In Italy they meet Mr. Emerson and George Emerson. George is young man who falls in love with Lucy. Mr. Emerson is an idealist and a dreamer. Only a couple of days after they get to Italy George kisses Lucy while standing in the middle of a waving field of grass. George does this with out her permission or discussion. Even though this surprises Lucy and backs away she still participates in the kiss that tells the readers that there is something in her heart that drives her toward George. Georges function in A Room with a View is clear: he is a source of passion in a society that is tightly sealed with convention, timidity, and dryness. When Lucy comes home to Britain she is proposed to by Cecil. She accepts the offer because she knows that it is the proper thing to do. Cecil is an intelligent, well-respected man but lacks the passion that George penetrates. When Cecil attempts to kiss Lucy it is very different than George. He first of all asks permission, then Cecil timidly moves in to kiss her, and lastly his glasses fall off. This example shows the difference between Cecil and George and how Cecil lacks the aggression an d desire that George has. Lucy has to make the decision between the mind and the heart. She is torn between Cecils world of books and conformity and Georges world of passion and nature. This decision is not easy for Lucy to make. Lucy came really close to marrying the wrong man due to her lack of thought. She has grown up and lived a life of proper existence. However, Lucy possesses passionate qualities they have just been repressed her entire life. Her only emotion outlet is the piano, in which she prefers dramatic pieces by Beethoven. She plays the piano in order to let out her frustrations brought on by her surrounding characters. Lucy is brought up to be proper and not outgoing or passionate. George will eventually show her how to be passionate and open to new ideas. George is a man that breaks the chains of conformity to free Lucys spirit and he does this efficiency. George kisses Lucy for the second time and he explains that love exists between them. He tells Lucy that she can not marry Cecil because he does not understand women and will never understand Lucy. George also explains that Cecil only thinks that he loves but in actuality only wants her for an ornament. George, on the other hand, wants her as his partner in the great adventure of life. Lucy has lied to herself and to everyone else around her until she is eventually cornered into tearfully admitting her love for George. A Room with a View is a love story about a young proper women who is engaged to a proper man she does not love, and the frantic efforts a another young man to her see what love is and that she loves him. Lucy struggles between what is expected of her and what she really wants. By the end of the novel, George will have offered Lucy a view out of the window of her life. George will have opened a window for her. British social comedy examines a young heroines struggle against straitlaced Victorian attitudes as she rejects the man her family has encouraged her to marry and chooses, instead, a socially unsuitable fellow she met on holiday in Italy. Classic exploration of passion, human nature and social convention. A Room with a View was published in 1908. It was one of Forsters earliest novels, and it has become one of his most famous and popular. E.M. Forster was twenty-nine at the time of publication; two earlier novels, Where Angels Fear to Tread and The Longest Journey, had been poorly received. A Room with a View was blessed with good reviews, but it would not be until 1910 and the publication of Howards End that Forster would have his first major success. The novel deals with a group of British characters in two major settings: Part One and the final chapter are set in Florence, Italy, and Part Two is set mostly in a quiet part of Surrey, England. Forsters characters, like Forster himself at the time of the novels writing, live in the time of the British Empires zenith. With possessions in every part of the globe, the British Empire was as yet untouched by the difficulties of the two world wars. The monarch of England was also the king of Canada and the emperor of India; English citizens enjoyed the fruits of a system of exploitation and oppression that touched the far corners of the world. The remnants of Victorian sensibilities were still very much alive. Prim and proper Brits worried about refinement, the virtue of young girls, and the control of the passions. But it was also a time of change. Women began to clamor more loudly than ever for equal rights. Socialists were challenging old ideas about class and religion, and artists and thinkers began to challenge Victorian attitudes about emotion and sexuality. A Room with a View was one of those challenges. The story of young Lucy Honeychurchs choice between propriety and love, the novel casts Socialists as heroes and prim spinsters as antagonists. Lucys dramatic choice at the end of the novel is not only a victory for passion, but for womans independence. It was common for British citizens, particularly young men and women, to take the grand tour of Italy. The idea was for educated Brits to expose themselves to the work of Renaissance and Roman artists and architects, but like tourists throughout the ages, many travelers only had a superficial experience of Italy. They stayed with other British travelers, looked down on the Italians, and went to museums and ancient churches with their books of art criticism in hand. Forster criticizes this kind of tourist, but with some gentleness and a good deal of humor. A Room with a View is wonderful social commentary, but it is no acrid satire. The novel prefers to laugh lovingly at its subjects, and in the end the good in people matters much more to Forster than their shortcomings. The novel deals with Lucys growth toward self-awareness; by the end, she has learned the importance of expressing passion honestly. At the time, Forster was at the beginning of his first important relationship. A Room with a View is dedicated to H.O.M., Hugh Meredith, Forsters first love and the model for George Emerson. Throughout the novel, Forster speaks with great insight on the subject of repressed passion and the war between desire and societys conventions. His experiences as a gay man at the beginnings of his first relationship undoubtedly had a great influence on the writing of the novel. His lack of sexual experience also explains some of the novels shortcomings; although he writes beautifully about the beginning stages of the courtship between Lucy and George, in the final chapter he seems less certain, less insightful. Still, the book is an accomplished and beautiful love story, full of cutting but ultimately generous insights. And there are unforgettable moments: the firs t kiss between George is Lucy, passionate and unexpected on a hillside covered with violets, is one of the finest kisses in modern literature. Propriety and Passion: The conflict between social convention and passion is a central theme of the novel. Lucys match with George, by social standards, is completely unacceptable. But it is the only match that could make her happy. Her match with Cecil is far more conventional, but marriage to Cecil would destroy Lucys spirit. The Emersons are truly unconventional people. They care almost nothing for propriety. Mr. Emerson, a Socialist, speaks with great feeling about the importance of passion and the beauty of the human body. The British characters of the novel have very strong ideas about the need to repress passion and control young girls. To achieve happiness, Lucy will have to fight these standards, many of which she has internalized, and learn to appreciate her own desires. The beauty of human beings: A Room with a View is social commentary, but Forsters depictions of people are ultimately generous. He gently mocks the Honeychurches for their bourgeois habits, but he does not shy from depicting their strengths. They are loving and sincere, generous with guests and with each other. Cecils greatest fault is that he is entirely too critical of people. He cannot appreciate the good in the simple country gentry with whom Lucy has grown up. Even Charlotte, the prim spinster who is a major obstacle to the love between Lucy George, is allowed to have a moment of grace. In the end, Forster appreciates his characters goodness much more than he mocks their faults. Travel and the idea of Italy: Travel is a powerful force in the novel, and at its best it can be a life-altering experience. The heart of travel is to allow a place to get under ones skin; staying at British pensions and scorning Italian peasants do not the constitute the best experience one can get out of Italy. Italy gives Lucy insights into her life back at Windy Corner. It changes her perspective of herself. Although her experiences there confuse her, in working through the confusion she becomes a self-assured and independent young woman. The beautiful and the delicate: Lucy asks in the first chapter if beauty and delicacy are really synonyms. One of Lucys important lessons is that beauty need not be refined; much is beautiful in the gesture of kindness that oversteps propriety, or the act of passion that ignores convention. Lucy has to learn to see beauty in things that her society scorns or condemns. Womans position and independence: The Emersons are fervent believers in the equality of men and women. Lucy is not a rebel at heart, but she is often frustrated by the limitation put on her sex. Her marriage to Cecil could never be one between equals. Cecil is not so much in love with Lucy as he is in love with some idea of what a woman is supposed to be. He constantly compares her to a work of art, which, although it may be flattering, also objectifies her and ignores that she is a living person. What Lucy needs, although she does not know it, is a relationship between equals. She has no desire to be protected or instructed. Connection between nature and man: One of Mr. Emersons convictions is that man and nature are inextricable from each other, and only the mistakes of civilization separate man from his natural state. Closely connected to the theme of passion and the body, this theme runs throughout the novel. Forster emphasizes it by having the weather often mirror the thoughts of his characters. He also connects George and Lucy to the land at key points. Passion and the body: If nature and man are inextricable from each other, it follows that there should be no shame for the body or passion. Societys conventions try to hide both. The body must be hidden, a thing of which one should feel ashamed; passions must be controlled and regulated by rules tied to class and gender. Lucy has to overcome these conventions if she is to allow herself to love George. The Medieval/the Renaissance/the Classical: Forster uses time periods to represent characters and their attitudes. Uptight Cecil is always associated with the medieval; George is associated with the myths of the classical world. Italy is the land of both the classical Roman world and the Renaissance, and Forster uses these eras as symbols of beauty and passion. Music: Lucys relationship to her music is an important insight into her character. Her playing is an indication that she has untapped reserves of passion; Mr. Beebe remarks that one day Lucy will live as well as she plays. Lucys music also articulates her feelings better than her words can, and after playing she is more certain of what she wants. The Muddle: Forster constantly uses the word muddle to describe Lucys state of mind. The muddle arises when everything that one has been taught suddenly is thrown into doubt. It is one of the marks of growing up. Lucys muddle is frightening and confusing, but in working through it she will become a stronger and wiser person. Class snobbery: Class snobbery is a constant feature of A Room with a View. The Emersons, because they are not refined, are the most frequent victims of this snobbery. Country gentry look down on those who work hard for a living; Cecil looks down on the suburban ways of country gentry. Lucy has to overcome the class bigotry that she has been taught. Short Summary Lucy Honeychurch, a young English woman, is vacationing with her cousin, Charlotte Bartlett, at an Italian pension for British guests. They are vacationing in Italy together, and currently they are in Florence. While bemoaning the poor views outside their windows, Lucy and Charlotte are interrupted by another guest, an old man by the name of Emerson. Mr. Emerson offers them a room swap; he and his son George are both in rooms that offer beautiful views of Florence. Charlotte refuses; for a woman to accept such an offer from a man would make her indebted to him. It would be a serious breach of propriety. But later that evening, after the intercession of another guest, a clergyman named Mr. Beebe, Charlotte accepts the offer. Their stay in Florence continues, and Lucy continues to run into the eccentric Emersons. They are socially unacceptable by the snobbish standards of the other guests, but Lucy likes them. One day, while Lucy is walking alone in Florence, she witnesses a murder. George happens to be there, too, and he catches her when she faints. On the way home, they have a strange, intimate conversation as they walk along the river. But George stirs up feelings in Lucy that she is not ready to face, and she resolves not to see him again. However, later that week, they both end up on a carriage ride into the hills near Florence. The various British travelers disperse and wander around the hills, and Lucy finds herself alone. She stumbles onto an earth terrace covered with violets, and finds herself face-to-face with George. He kisses her, but the kiss is interrupted by Charlotte. The next day, under Charlottes direction, Lucy and Charlotte leave for Rome. Part 2 begins after the passage of several months. We are back at Windy Corner, the Honeychurch home in Surrey, England. In Rome, Lucy spent a good deal of time with a man named Cecil Vyse. The Vyses and the Honeychurches are on friendly terms, but Cecil and Lucy only knew each other superficially before Italy. In Italy, Cecil proposed to Lucy twice. She rejected him both times. As Part 2 begins, Cecil is proposing yet again. This time, she accepts. Now that they are engaged, Cecil and Lucy must spend time with Lucys various neighbors. Cecil, an aristocratic Londoner, despises the ways of the country gentry. He also dislikes Lucys brother, Freddy, and is not overly fond of Lucys mother. But Lucy puts up with it. At Charlottes request, she has never told anyone about her kiss with George. But before too long, the Emersons move into Cissie villa, a home not far from Windy Corner. Lucy is forced to face George Emerson again, but she manages to deal with him at a distance. She continues her engagement to Cecil, even though signs indicate that she is anxious about the marriage on a deep psychological level. To the reader, it is obvious that they are completely unsuitable for each other, but Lucy persists in the engagement. Soon, things come to a head: Charlottes boiler is broken, and she comes to stay as a guest at Windy Corner. And during her stay, Freddy, who has befriended George, invites George to come play tennis. It is all to take place on Sunday, and Lucy is terrified of what might happen. On Sunday, Cecil refuses to play tennis and pesters everyone by reading aloud from a bad British novel. Lucy soon realizes that the novel is written by Miss Lavish, a woman who stayed at their pension in Florence. Cecil reads a particularly humorous passage aloud, but Lucy sees nothing humorous about it: it is a fictional recreation of her kiss with George. The names are different, but the situation is unmistakable. She realizes that Charlotte told Miss Lavish what happened. George is also present for the reading of the passage. On the way back to the house, George catches Lucy alone in the garden and kisses her again. Lucy confronts Charlotte angrily about her indiscretion. She resolves to put George in his place. She has Charlotte sit in the room as support and witness, and she orders George never to return to Windy Corner. George argues with her passionately. He tells her that Cecil is stifling and unsuitable for her; Cecil will never love her enough to want her to be independent. George loves her for who she is. Lucy is shaken by his words, but she stands firm. George leaves, heartbroken. However, later that night, Cecil refuses again to play tennis with Freddy. Something in his refusal makes Lucy see him truthfully for the first time. She breaks off the engagement that very night. But Lucy still cannot admit to anyone, including herself, her feelings for George. Rather than stay at Windy Corner and face George, she resolves to leave for Greece. But one day not long before she is supposed to leave, she goes to church with her mother and Charlotte and meets Mr. Emerson in the ministers study. Mr. Emerson does not know that Lucy has broken off the engagement, but Lucy realizes before long that she cannot lie to the old man. She talks with him, and Mr. Emerson realizes that she has deep feelings for George. He presses the issue, forcing her to confront her own feelings. Finally, she admits that she has been fighting her love for George all along. The novel closes in Florence, where George and Lucy are spending their honeymoon. Not having her mothers consent, Lucy has eloped with George. Things are difficult with her family, but there is hope that it will get better. Whatever happens, George and Lucy have each other, and their life together promises to be full of happiness and love. We open in Florence at the Pension Bertolini, a pension for British travelers. Young Lucy Honeychurch and her cousin, Charlotte Bartlett, are bemoaning the poor rooms that they have been given. They were promised rooms with views. The two women sit at dinner in their pension, along with the other guests. Lucy is disappointed because the pension hostess has turned out to be British, and the dà ©cor of the pension seems lifted right out of a room in London. While Miss Bartlett and Lucy talk, an old man interrupts them to tell them that his room has a nice view. The man is Mr. Emerson; he introduces his son, George Emerson. Mr. Emerson offers Miss Bartlett and Lucy a room swap. The men will take the rooms over the courtyard, and Lucy and Charlotte will take the more pleasant rooms that have views. Miss Bartlett is horrified by the offer, and refuses to accept; she begins to ignore the Emersons and resolves to switch pensions the next day. Just then, Mr. Beebe, a clergyman that Lucy and Charlotte know from England, enters. Lucy is delighted to meet someone she knows, and she shows it; now that Mr. Beebe is here, they must stay at the Pension Bertolini. Lucy has heard in letters from her mother that Mr. Beebe has just accepted a position at the parish of Summer Street, the parish of which Lucy is a member. Mr. Beebe and Lucy have a pleasant talk over dinner, in which he gives Lucy advice about the sites of Florence. This vacation is Lucys first time in Florence. Soon, almost everyone at the table is giving Lucy and Miss. Bartlett advice. The torrent of advice signifies the acceptance of Lucy and Miss Bartlett into the good graces of the pension guests; Lucy notes that the Emersons are outside of this fold. After the meal, some of the guests move to the drawing room. Miss Bartlett discusses the Emersons with Mr. Beebe; Beebe does not have a very high opinion of Mr. Emerson, but he thinks him harmless, and he believes no harm would have come from Miss Bartlett accepting Mr. Emersons offer. Mr. Emerson is a Socialist, a term that is used by Mr. Beebe and Miss Bartlett with clear disapproval. Miss Bartlett continues to ask Mr. Beebe about what she should have done about the offer, and if she should apologize, until Mr. Beebe becomes annoyed and leaves. An old lady approaches the two women and talks with Miss Bartlett about Mr. Emersons offer. Lucy asks if perhaps there was something beautiful about the offer, even if it was not delicate. Miss Bartlett is puzzled by the question; to her, beauty and delicacy are the same thing. Mr. Beebe returns: he has arranged with Mr. Emerson to have the women take the room. Miss Bartlett is not quite sure what to do, but she accepts. She takes the larger room, which was occupied by George, because she does not want Lucy to be indebted to a young man. She bids Lucy goodnight and inspect her new quarters, and she finds a piece of paper pinned to the washstand that has an enormous note of interrogation scrawled on it. Though she feels threatened by it, she saves it for George between two pieces of blotting paper. Analysis Lucy is young and naà ¯ve; she is bright but not brilliant, although she has enough imagination and compassion to begin to look beyond the social conventions of her class and time. Forsters novel is full of insightful social commentary on the stuffiness of British social conventions. Modern readers are often surprised by Miss Bartletts deep anxieties about accepting a room trade with the generous but socially outcast Emersons. Miss Bartlett is acting under social pressures from several different directions. For one thing, Lucys mother has paid for Miss Bartletts travel expenses, and Miss Bartlett therefore feels responsible for guarding Miss Honeychurch from any possible harm. For Miss Bartlett, life is lived in accordance with what are arguably very precious and ridiculous concerns. Nothing is worse than a scene, and she must also guard Lucy from feeling obligation to a young man. Sex is a source of terrible anxiety for the British of this period, and a young womans reputation must be guarded at all costs. Lucy brings up an important theme of the novel when she asks about the delicate and the beautiful. Lucy wonders if delicacy and beauty might be different things, while Charlotte assumes that they are synonymous. As her social world defines beauty and delicacy, the two qualities are one and the same; beauty is found in politeness, in circuitous and subtle conversation, in avoidance of direct confrontation or over-earnest expressions of emotion. There is not beauty, therefore, in Mr. Emersons generous offer of a room trade. But Lucy is more imaginative than her cousin, and she is able to see that there is beauty in Mr. Emersons socially clueless but generous offer. He is completely unaware of the anxiety he is causing Miss Bartlett; either that or his is completely unconcerned about it. The important thing to him is the generosity of his offer. He does not intend to put Lucy or Charlotte under obligation. He sincerely thinks that a room with a view should go to the one who most enjoys the view. Lucy will have to learn to come to her own understanding of beauty. We see more of Lucys sensitivity and naturally sympathetic and sensitive disposition when she realizes that she and Charlotte have been accepted by the other guests of the pension. She sees that Mr. Emerson and George have not been accepted, and this knowledge makes her feel sorry for them. But Lucy is not strong enough yet to affect the world around her. Note that Charlotte handles all the details of the room trade, and Lucy is not yet confident enough to articulate her doubts about the stuffiness and petty concerns of her social world. Italy and travel make another important theme. The heart of this theme is a new places ability to get under the skin of the traveler, transforming her. Though she is not yet fully aware of it, Lucy longs for this kind of experience. She is deeply disappointed by the Pension Bertolini, which to her seems like another piece of England. She wants to go out into Italy and feel it fully, as richly as she can, away from the safety of British dà ©cor and sensibilities. The pension is juxtaposed to the world outside; the inside of the pension is decorated like a room in London. British social conventions are preserved and protected from the foreign country that surrounds the pension on all sides. The pension protects the guests from Italy, and so it prevents the transforming experience that is the best result of travel. Italy is also a direct challenge to the idea of beauty and delicacy being identical. Italys beauty is refined and sophisticated, but there is nothing delicate about its colo ssal Roman ruins, dramatic countryside, or rustic peasants. Lucys longing for a room with a view is a metaphor for her longing to connect with Italy and the new experiences the country offers. Instead of a view of the courtyard, she wants a view of the country. The window opening out into Florence symbolizes Lucys openness to a new world. Chapter Two In Santa Croce with No Baedeker: Summary: Lucy looks out her window onto the beautiful scene of a Florence morning. Miss Bartlett interrupts her reverie and encourages Lucy to begin her day; in the dining room, they argue politely about whether or not Miss Bartlett should accompany Lucy on a bit of sightseeing. Lucy is eager to go but does not wish to tire her cousin, and Miss Bartlett, though tired, does not want Lucy to go alone. A clever lady, whose name is Miss Lavish, intercedes. After some discussion, it is agreed that Miss Lavish and Lucy will go out together to the church of Santa Croce. The two women go out, and have a lively (but not too involved) conversation about politics and people they know in England. Suddenly, they are lost. Lucy tries to consult her Baedeker travel guide, but Miss Lavish will have none of it. She takes the guide book away. In their wanderings, they cross the Square of the Annunziata; the buildings and sculptures are the most beautiful things Lucy has ever seen, but Miss Lavish drags her forward. The women eventually reach Santa Croce, and Miss Lavish spots Mr. Emerson and George. She does not want to run into them, and seems disgusted by the two men. Lucy defends them. As they reach the steps of the church, Miss Lavish sees someone she knows and rushes off. Lucy waits for a while, but then she sees Miss Lavish wander down the street with her friend and Lucy realizes she has been abandoned. Upset, she goes into Santa Croce alone. The church is cold, and without her Baedeker travel guide Lucy feels unable to correctly view the many famous works of art housed there. She sees a child hurt his foot on a tomb sculpture and rushes to help him. She then finds herself side-by-side with Mr. Emerson, who is also helping the child. The childs mother appears and sets the boy on his way. Lucy feels determined to be good to the Emersons despite the disapproval of the other pension guests. But when Mr. Emerson and George invite her to join them in their little tour of the church, she knows that she should be offended by such an invitation. She tries to seem offended, but Mr. Emerson sees immediately that she is trying to behave as she has seen others behave, and tells her so. Strangely, Lucy is not angry about his forwardness but is instead somewhat impressed. She asks to be taken to look at the Giotto frescoes. The trio comes across a tour group, including some tourists from the pension, led by a clergyman named Mr. Eager. Mr. Eager spews commentary on the frescoes, which Mr. Emerson heartily disagrees with; he is skeptical of the praise and romanticizing of the past. The clergyman icily leads the group away. Mr. Emerson, worried that he has offended them, rushes off to apologize. George confides in Lucy that his father always has that effect on people. His earnestness and bluntness are repellent to others. Mr. Emerson returns, having been snubbed. Mr. Emerson and Lucy go off to see other works. Mr. Emerson, sincere and earnest, shares his concerns for his son. George is unhappy. Lucy is not sure how to react to this direct and honest talk; Mr. Emerson asks her to befriend his son. She is close to his age and Mr. Emerson sense much that is good in the girl. He hopes that these two young people can learn from each other. George is deeply saddened by life itself and the transience of human ex istence; this cerebral sorrow all seems very strange to Lucy. George suddenly approaches them, to tell Lucy that Miss Bartlett is here. Lucy realizes that one of the old women in the tour group must have told Charlotte that Lucy was with the Emersons. When she seems distressed, Mr. Emerson expresses sympathy for her. Lucy becomes cold, and she informs him that she has no need for his pity. She goes to join her cousin. Analysis: Although Miss Lavish prides herself on being original and unconventional, Forster subtly shows that her radicalism is polite, precious, and limited. She disapproves of the Emersons just as much as everyone else does, and though she pretends to be worldly and well traveled (she takes away Lucys Baedeker guide), she gets the two women lost. Nor does she understand the value of getting lost: she is so fixated on getting the women to Santa Croce that she rushes past the beautiful Square of the Annunziata without noticing a thing. Her attitude toward the Italians is patronizing in the extreme: she defines democracy as being kind to ones inferiors. Although Forster is writing incisive social commentary on the stuffiness of British society, he uses Miss Lavish as an example of a certain kind of false rebelliousness. She is ultimately as snobby and precious as everyone else, and her brand of radicalism tends to reinforce stuffy conventions rather than challenge them. Lucy is not a brilliant girl, and she lacks the originality and confidence to make her own judgments about art. In Santa Croce, she longs for her Baedeker guide so that she can know good art from bad. She lacks the confidence to just look at the paintings; she wants to know which frescoes have been pronounced by the critics to be truly beautiful. Lucy has some generosity of spirit and often feels uncomfortable with stifling social conventions, but she is not a genius or revolutionary. She is still young and very naà ¯ve; by the novels end she will be a much wiser and independent person. Part of Forsters brilliance is his restraint. He resists the temptation to make Lucy into a brilliant firebrand, and instead makes her to be, in many ways, a very typical girl for her class and education. She is often caught between convention and an inner sense of what is beautiful rather than delicate. She is unquestionably drawn to George Emerson. In Santa Croce, she notices that his face is rugged and handsome, and she also notices the strength and physical attractiveness of his body. But his melancholy attitude puzzles her, and his angst seems humorous to her in some ways. Mr. Emerson compares him to the child that stumbled and hurt his toe on a tomb statue of Santa Croce. The tomb becomes a symbol of mortality, and George has stubbed his too; George is upset by mortality and the transience of human existence. Life itself hurts and puzzles him. Mr. Emersons social awkwardness and earnestness combine to make him a very unpopular man. Even Lucy rebuffs him at the end of this chapter, resenting his pity for her. But we can see from his attempted apology to Mr. Eager that he does not mean to offend; in fact, he earnestly desires that everyone should always have a nice time. And his criticism of Mr. Eagers romanticizing of Giottos art and time has its own valid perspective, although Mr. Emerson has difficulty expressing his ideas tactfully. Cha

Moreover, it has a key role to play in sustainable construction, since it needs less effort in its manufacture. These facts have not only led to many inventions in the field of concrete but have also led to many studies in order to improve its quality, reducing the cost of implementation and make the concrete friendly with the environment; besides, amending its aesthetical appearance when it is used as a structural construction members. Nowadays, It can be seen that as a result of the research progressions concerned the concrete technology, various types of concrete such as High Performance Concrete, Ultra High strength concrete, Light Weight Concrete, Architectural Concrete and Self compacting concrete (SCC) are commonly heard not only among engineering Society but ordinary people also. In this prospective, the awareness and more knowledge regarding the concrete types should be considered. In fact, civil engineers should have more awareness and information about concrete types so as to be able to keep themselves abreast with the most recent developments, new technological innovations and future prospects. Regarding the SCC, it can be considered as a one of the recent developing types of contemporary concrete. It is an innovative concrete mixture that can be mold into place without the use of vibrators to form a product free of empty spaces within the formwork. It is commercially known by various names such as self-consolidating concrete, self-compacting concrete, self-leveling concrete, or rheoplastic concrete (Mehta and Monteiro 2006: 476). The Prototype of (SCC) was first developed in 1988 in Japan, by Professor Ozawa in 1989 at the University of Tokyo (Okamura and Ouchi 2003).However; the name of SCC was given to this Prototype by Okamura of the University of Tokyo. The aim of this project is to review or gain understanding about SCC in terms of its ingredients, mixture requirements and mechanism for achieving self-compatibility depending on previous researches. It also evaluates the results of using this type of concrete in some modern implementations. Finally, it demonstrates the benefits and potential disadvantages of using SCC in terms of safety, economy, and construction quality. 1. Historical reasons for development of SCC According to Goodier (2003:405), the initial emergence of Self compacting concrete was in Japan in the late 1980s and its subsequent introduction into Europe through Sweden in the mid- to-late 1990s. In the 1980s, the problem of the durability of concrete structures and acceptable compaction were the main subject that was considered in Japan; meanwhile, the skilled workers were required in order to achieve durable concrete and acceptable compaction. It seems to be the lack of the numbers of skilled workers in Japans construction industry at this time was the main reason for decrease in the quality of construction work. One solution for achievement of durable concrete structures was the using of self-compacting concrete, which can be compacted into every corner of a formwork, completely by means of its own weight and without the need for vibrating compaction. This means that it can be gained sustainable concrete structures and acceptable compaction by using minimum number of workers and equipment (Fig.1).Moreover, the use of SCC was also implemented to provide economic, social and environmental benefits over conventional vibrated concrete construction. (Okamura and Ouchi, 2003:5)The conception of this type of concrete was proposed by Professor Hajime Okamura in 1986 who Studied the development of self-compacting concrete and comprised a fundamental study on the workability of concrete (Okamura and Ouchi 2003). 2. Ingredients and requirements of SCC mixture With respect to its composition, SCC includes the same components as conventionally vibrated normal concrete, which are cementitious materials, different sizes of aggregates, and water, additives and admixtures. On the other hand, in the SCC, high volume of super plasticizer for reduction of the liquid limit and for better workability, the high powder content as lubricant for the coarse aggregates, as well as the use of viscosity-agents to increase the viscosity of the concrete have to be taken into account (Dehn et al. 2000). Regarding to the requirements of SCC mixture, a concrete mix can only be classified as SCC if the requirements for all the following three workability properties are fulfilled which are filling ability, Passing ability, and Segregation resistance (Abdul Hameed 2005). Filling ability or flow ability means that, the SCC must have the ability of to fill a formwork entirely under its own weight. According to the European Guidelines for Self Compacting Concrete (2005: 20), the tests that are used for assessing filling ability of the fresh SCC are Slump-flow, and Kajima box. Passing ability means that the SCC must have the ability to flow through restricted places, such as spaces between steel reinforcing bars, sharp corners, and small openings, without using any means of vibrators (to flow by its own weight), also without produce any blocking or hindrance during its use. According to the European Guidelines for Self Compacting Concrete (2005: 20), the tests that can be used to determine passing ability are U-box, L-box, Fill-box, and J-ring test methods. Segregation resistance means that the SCC must meet the filling ability and passing ability with Homogeneous composition during and after the process of transport and placing. It is generally accepted that the three main properties of fresh self-compacting concrete must then be maintained for required period of time after mixing. 3. Mechanism for achieving self-compact ability of fresh concrete Okamura and Ouchi (2003:5 ) suggested that In order to achieve self -compact ability of fresh concrete, deformability of past ( mortar) and resistance to segregation between aggregate particles and mortar when the concrete flows through the restricted zone of reinforcing bars, have to be considered. Okamura and Ozawa (1995) have utilized the following methods to achieve self-compact ability of fresh concrete. Firstly, they limited the amount of aggregate content (coarse aggregate  ­ 50% of the concrete volume and sand ­ 40% of the mortar volume).Secondly, they used low water/powder ratio, with higher dosage of superplasticizer admixture. According to SHETTY (2005:573), using superplasticizer which is used with concrete components as an essential chemical admixture, leads to increase the workability of fresh concrete without regard to reducing water content in the concrete mixture. When concrete is placed in to the formwork, the relative distance between the concrete particles will decrease. As a result, the frequency of collision and contact can increase and consequently, internal frictions between concrete particles also increase, especially near hindrances. Research has found that the energy which is required for flowing the concrete during the casting is consumed by the increased internal friction between particles, and resulting in blockage of aggregate particles to flow through confined places. For this reason, limiting amount of coarse aggregate, whose consume more energy, to a level lower than normal will increase the efficiency of concrete flow ability and avoid concrete particles from this kind of blockage. To prevent the interlocking (blockage) incidence of coarse aggregate when the concrete is poured through obstacles, highly viscous past is required. Since the concrete which has a high viscosity prevents localized increases in internal stress as a result of the approach of coarse aggregate particles (Okamura and Ouchi 2003:6). 4. Some applications of SCC Based on the researches which have been performed on SCC over the last two decades, it can be said that the use of SCC has been increased dramatically. It is commonly used in place of traditional concrete not only to reduce time of construction projects but also to reduce the cost of construction projects. According to Okamura, Whatever conventional concrete can do, SCC can do better, faster, and cheaper, especially for concrete elements with special textures, complex shapes, and congested reinforcements (Mamaghani et al. 2010:5). It can be seen that there are a range of using of SCC around the world. Many researches show that this type of concrete is commonly used within cast-in-place (in field) and precast construction. Furthermore, it is also used in the structural and architectural concrete sections where the tightness of steel reinforcement and /or surface quality is required. However, other implementations of SCC include drilled piers, caissons, bridge abutments and walls. In Japan, the first use of SCC was in 1991 for the construction of bridge towers (Daczko and Vachon, 2006:638). While the first large-scale project using SCC was the Akashi-Kaikyo Bridge, which completed in 1998. It is estimated that the construction time of this project was reduced by 20%, from 2.5 to 2 years due to the use of SCC (ibid.). A second implementation was performed, in 1998, for the building of the walls of a natural gas tank for the Osaka Gas Company. The estimated amount of SCC that was been using during the construction is approximately 12000 m3. It was observed that the construction time of the project was also shortened from 22 to18 months meanwhile; the number of labours worked in the project was reduced from 150 to 50 (ibid.). In Sweden, the Sodra Lanken Project (SL) was one of the largest infrastructure projects that were implemented by using SCC. The total cost of this project was estimated at approximately 800 million USD. Ouchi et al. (2003) point out that the SL project included seven major junctions, with bridges, earth retention walls, tunnel entrances and concrete box tunnels; the overall length of the rock tunnels were 16.6 kilometers. Also, the volume of concrete used in the project estimated at 225,000 cubic meters. It was observed that SCC was used in the project because it included structural sections that were required high demands on aesthetics, and at the same time they were difficult to compact by normal vibration. Recently, the New York State Department of Transportation (NYSDOT) has used significant amounts of SCC. Mamaghani et al. (2010: 5) report that the current projects in the New York State include the use of SCC for prestressed, high performance concrete bridge beams on the Brooklyn-Queens Expressway from 61st Street to Broadway in New York City. According to a NYSDOT official, The performance of SCC has been excellent. NYSDOT is achieving very good quality with a minimum of defects. There has been a slightly higher cost for admixtures, but NYSDOT saves on labor. It can be anticipated that, in the future, concrete elements or buildings will be designed considering SCC from the start with shapes, textures, and structures that would be impossible to achieve with normal concrete. 6. The advantages of using SCC in engineering implementations Improved concrete construction environment The SCC is considered an environmentally friendly material. Firstly, regarding the construction site, the SCC can eliminate the need for vibration to compact the concrete; since SCC has ability to fill the form work completely under its own weight. The compaction of fresh concrete by vibration is generally recognized as a heavy physical job and an unpleasant activity in the concrete construction process. Moreover, using the vibration can also cause high noise levels which are not good for public health; especially the health of the operators. Secondly, the acceleration generated by vibrators can reach 0.70 to 4m/s2 and has potential to injure the vibrator operator. Hence, eliminating the vibration significantly improves health and the environment on a concrete construction site (Li 2011). It can be said that some skills and experience are needed for vibrator operators in compacting fresh concrete in order to gain a satisfactory concrete. Lack of experienced workers in many regions ma y lead to decline the quality of concrete. It is generally accepted that the application of SCC can solve this problem and ensure consistent high quality for concrete structures. Cost-efficient production With respect to the required number of labours on the construction project compared with conventional (normal) concrete types, the SCC needs less number of workers and shorter times for placing (casting). It is generally believed that by using SCC, the process of production can be accelerated, and the quality of concrete structures can be improved as well. According to Peterson (2008:66), the elimination of vibration means rationalised casting technique with less need of personnel and/or more rapid production cycles and thereby presumptively reduced production costs. New opportunities with respect to architectural and structural applications SCC benefits structural and architectural applications. New types of structural elements, which were not possible to be produced by traditional concrete, can be produced by using SCC because these types of structural elements include different types of steel or concrete structural elements with more complex shapes, which are thinner with a much heavier reinforced cross section. With regard to the construction of heavy structure (mega structure) fields such as multistory building, high rise building or ultra-high rise building, since the SCC does not need any vibrators and finishing surface tools, it means that it reduces lifting of heavy equipment and reduces handling of fresh concrete by labours. Also, there is no need of repairs to hardened concrete as there are no chances for producing any remarkable voids. With respect to construction consideration, Ouchi et al. (2003:18) found that When placing a new layer of SCC on old SCC, the bond between the old and new SCC is equal to or better than in the case of conventional vibrated concrete. On this basis it may be inferred that the normal vibrated concrete needs vibration to provide well compacted concrete, while SCC will not need the vibration and consequently it will not destroy the concrete. Regarding the durability of SCC, researches have shown that ingredients of SCC and the avoidance of using vibration have a significant role in improving the microstructure of the concrete (Holton 2004). The ingredients and avoidance of using vibration acquires the concrete many benefits. First, they gain the concrete lower surface permeability and absorption against harmful chemical materials such as chlorides and carbon dioxide which have a negative effect on the durability of concrete. Second, they improve the resistance of the concrete against freezing- thawing which the concrete may be subjected during different seasons. Finally, they play a key role in producing a good bond between the concrete materials and the steel reinforcement after the concrete hardening. Another advantage of the SCC is that, it can be used when the normal placement of concrete is difficult e.g. tunnel linings, heavily reinforced structures, prestress concrete structures and other inaccessible places. One example is the design of the Millennium Tower in Vienna, which is described as it had been impossible to build without using SCC (Peterson 2008:66). Moreover, Using SCC for the construction of tall building, bridge tower, and tunnels leads to increase the use of concrete pumping. Nowadays, by using special high- pressure pumps, SCC can be pumped distance as far as 1400m horizontally or as high as 420m vertically (Li 2011:130). 7. Disadvantages and obstacles for the implementation of SCC Absence of acceptance SCC Despite the fact that the SCC has a great numbers of stunning and successful applications; it was only hesitantly accepted by the industry. This could be attributed to a number of reasons (Holton 2004).First of all, the standard specification tests that were used for testing and evaluation conventional concrete was no longer useful for SCC. As a consequence, it was very difficult to smoothly put SCC into practice; also, before using SCC, the intensive preparation efforts were required in the laboratory in order to achieve an appropriate quality. Second, the sensitivity of SCC is increased proportionally with change of its mix proportions (particularly the water content) or with change of the environment such as temperature variations. This increased sensitivity produces an extra hindrance to the wider use of SCC as it puts a prices working at the production field (ibid.). Potential disadvantages and obstacles of using SCC Based on the recent studies, despite the possible benefits of SCC compared to normal concrete, it can be seen that the implementation of the SCC is still noticeably limited. According to Peterson (2008:67), the obstacles for increased application of this type of concrete can be attributed to technical and non- technical aspects. In the SCC, the quality of mix design and the conditions of casting concrete should be considered; slight differences in mix proportions or during its casting may cause a number of technical quality problems that may pose as hindrances for future use of SCC. Despite of the intensive and extensive studies on SCC, it can be seen that there are still some unsolved technical problems and a great number of technical difficulties related to SCC. Peterson (2008:67) described these problems in many aspects; such as the problems related to the quality production of the ready-mix design and the Problems related to the hardened SCC especially when there is a low surface quality which leads to reduce fire resistance due to spalling, increase cracking owing to early shrinkage. It is widely accepted that SCC tends to dry faster than traditional concrete, since there is slight or no bleeding water at the surface before it is hardened. For this reason, SCC should be cured when it is practicable after placement to avoid the incidence of surface shrinkage cracking. Moreover, Peterson (2008:71) indicates that although the SCC has been considered as one of the main important invented technology for a more rational way of building with cast in-situ concrete; there are some projects where SCC has led to create technical problems such as concrete segregation with non-acceptable surfaces, concrete cracking owing to plastic shrinkage and formwork failure due to the high form pressure that may be produced as a result of the flow ability feature of SCC. It would appear that further studies are required to achieve a durable and fully satisfying concrete product. Conclusion It can be concluded that SCC helps to improve the environment of the construction locations (reducing noise produced in the plants and construction fields) and reducing the exposure of labours (Reduction manpower) where concrete is being casted. In the other word, the SCC is an ideal type of concrete that can be used for narrow spaced of reinforcement and architectural demanding sections, or, in more general , for all structural applications where require higher efforts in order to gain sufficient compaction. Furthermore, it can be seen that SCC offers many other benefits for the precast, prestressed concrete sector and for cast-in-place construction such as eliminated problems related to vibration, faster construction, gaining higher strength and better quality for the concrete after hardening. On the other hand, Although SCC can have many advantages and significant effects on the engineering applications such as its importance role in reducing the project construction time period, it can be said that special attention should be concentrated on particularly, in terms of selection the suitable ingredients of SCC mixture before the production (mix design of SCC). It can still be expected that, in the future, using SCC will help engineering designer (architects and structural engineers) to design concrete sections or structural elements which would be impossible to achieve with conventional concrete. Based on these facts it can be said that SCC will have a bright future.
