3 Stages of Computer Science Research Paper Writing 3 Tricks to Use

3 Stages of Computer Science Research Paper Writing 3 Tricks to Use Everything starts with†¦ a dream? Many people believe that everything starts with the science – knowledge about the world based on examining, testing, and proving the facts. It is worth to state that in the mid- to late-19th century, everything started to conform to computer science. Today, a career in the field of computer science is worthwhile and gainful for any young enthusiastic scientist. Is it your dream to become highly competent in Computer Science? So, be ready to work hard not only on programming languages, scientific computing or software engineering, but also in academic writing. Many research papers are expected of students to be prepared during a term. Have already felt the pressure of academic works? This guide is to simplify the paper writing process so that more time will be found for the other activities on Computer Science like programming a useful app. 3 Stages of Successful Research Paper Writing You should treat research paper writing as an activity that takes considerable time and efforts. It cannot be a one-step affair – just take a pen or a keyboard to create a research paper. The basic rule of any type of writing, including research paper writing, is to know what you are going to write BEFORE you start writing and go over your writing a few times AFTER you finish writing. Let’s divide the writing process into 3 distinct stages: prewriting, writing, and post-writing. It is important for any writer to work through each of these stages in order to ensure that a polished, complete piece of writing is produced. Prewriting is a process when you get prepared for writing itself. It doesn’t mean that you don’t need to write at all at this stage. You can be engaged in taking notes while gathering information for your research. For example, you can research in the library or on the Internet. Besides the researching process, this stage involves thinking (here you are better to have strong critical and analytical thinking skills), brainstorming, outlining, and so on. In other words, you are involved in generating some research ideas. However, this activity occurs throughout the writing process, so be open to new discoveries. Writing is a process when you have enough knowledge and data to write a research paper. Here is a stage where you need to connect your idea into sentences and even logically complete paragraphs. Don’t neglect drafting at this stage. You can’t get the content of your research paper on Computer Science out of your head and down on paper as a neat-book. You should have a rough draft before completing a paper. Otherwise, you risk losing essential marks on the poorly-written/ organized papers. Don’t risk in such a way. Tell yourself what you know and think about a research topic, then present it to your readers fully. Post-writing is a process when you refine your research paper. When you see that everything you want to cover on a topic is mentioned in your research paper, it is time to revise the entire paper by checking it for mistakes in grammar, sentence structure, spelling or punctuation. Your task is to make each sentence and paragraph as concise and accurate as possible. 3 Prewriting Tips for Your Research Paper It may be very difficult to get started with research paper writing. ‘Today, I have headache attack’, â€Å"Tomorrow, I’ll need to come to a birthday party† are typical flimsy denials from doing a research paper. However, there are real serious obstacles in starting to write a research paper. For example, you simply have no idea about WHAT you need to research. Exactly at the prewriting stage, you should foresee what you want your final research paper on Computer Science to look like. Let’s base on the experience of David J. Malan, Gordon McKay Professor of the Practice of Computer Science from Harvard University. Define the research area of Computer Science and a relevant topic for it. The given subject combines many other fields in which different research areas are open for your paper. Find a narrow angle from which you will develop your research paper. Make sure you are aware of any specific requirements you may have from your instructors – any study limitations or methods. Analyze all possible information sources if needed to make the right decision concerning a topic. It should correspond to 3 important points when selecting it. Budget your time needed to write a computer science research paper. Remember that even a college essay 1000 words long may take a few days to properly complete. So, it isn’t a good idea to postpone research paper writing to the last minute! According to the guide for effective time management, it is possible to control procrastination if you plan when you will do a specific research task, for example, to do a literature review. Brainstorm any ideas and thoughts for your computer science research paper. If you think that the idea to discuss the SQL schema is relevant to your research, come up with it in an outline. Truth be told, having an outline in front of your eyes allows you to brainstorm much more quickly. Arrange your preliminary ideas in an outline with a logical order. It should suit the common paper structure: introduction, body (literature review, methodology, results, discussion), and ending. Put ideas in sub-groups accordingly to develop them into paragraphs in every section. Trick #1. ‘How to avoid plagiarism in my research paper on Computer Science?’ Despite the fact that most of your research paper should be written in your own words, you may use someone’s words or ideas. When using sources in your research papers, you can avoid plagiarism by placing those words and ideas within quotation marks and crediting the information source in the reference list. Remember that you don’t need to cite a source when common knowledge is given, What belongs to common knowledge in Computer Science? For example, the fact that Alan Turing (1912–1954) was one of the early founders of the field (his famous paper is entitled ‘On Computable Numbers with an Application to the Entscheidungsproblem’ is in the public domain. Usually, this knowledge is found in reference works, like Encyclopedia.com or any other one. Besides, you can find some field-specific common knowledge, like 10 facts about Computer Science to know. 6 Computer Science Research Paper Writing Tips from Our Academic Writers Well, you’ve arrived at the most important stage of writing – the stage when you should note everything that you plan. But how to do it effectively? Remember the following points concerning every part of your research paper: The introduction is a part where you’re expected to discuss the basic ideas that you are going to explore in your research paper. Make it quite informative and direct in the following way: A literature review is a part that discusses published information in Computer Science. As you deal with a particular subject area, you need to write a summary and synthesis of the sources concerning your research topic. In other words, show how your topic is interpreted by the other researchers. A methodology chapter is devoted to the methods that help you investigate a research problem. Readers need to know how your research findings are obtained for better understanding the problem. The results section is a place where you’re required to report the findings of your research. It is better to use a systematic approach to the description of your results. Start highlighting the observations that are most relevant to the topic under consideration. The discussion is a part that is aimed at interpreting and describing the significance of your findings. You can compare and contrast the findings of previous studies to support the overall importance of your results. The conclusion is a part that summaries the main ideas covered. Additionally, you can provide some recommendations for new areas for future researches in the given field of study. Trick #2. ‘How to create an informative title for my research paper?’ Making up a title is a really difficult task, especially when it’s a research paper that you are going to working on. Besides you and your professor, there are many people who would like to read your paper. So, how to attract their attention to your research? Specify the type of your research in the title and include the key terms of your topic. Remember that the readers should know what they take in hand after looking at the paper title. If they meet vague terms, they are unlikely to catch the main idea of your research, whether you were trying to analyze or describe. Be as precise as possible in your title ideas. Some topics on Computer Science are as follows: Home-based Virtual Reality Systems: An Overview of System Software and Application Software; Networking Protocols Description: What Are Packet Switching Techniques Used?; An Analysis of Wireless Multimedia Sensor Networks and Their Performance; Software Sizing: 3 Approaches of Component-Based Software System: What Is Requirements Engineering?; Artificial Intelligence: A Sentiment Analysis, Automated Reasoning and QA Systems; Is a Natural Language Knowledge Representation Independent/Semi-Independent?; Design and Implementation of Web Services for Information Systems; 5 NoSQL Database Schemas: An Evaluation of Its Significance. 3 Post-Writing Tips for Your Research Paper No academic paper should be submitted without looking through it at least once! Twice is even better. You should devote all your efforts that are left or can be found in a day or two to prevent any embarrassing mistakes (such as spelling mistakes, or mistakes in word choice). When you revise a research paper, you’re able to evaluate its content. Make sure you actually have what you intended in the prewriting stage. Trick #3. ‘How to revise a research paper on my own?’ If you don’t trust anyone your work, you should do proofread it on your own like a pro. Go through the following checklist when revising: Did I actually write on the required topic?; Is there enough or too much evidence supporting a topic? Are paragraphs and sentences logically related to each other? Don’t I repeat the same ideas several times? In addition to the above mentioned, you should pay attention to word order in sentences (in the academic English language, the direct word order is used – Subject → Verb → Object), verb tenses rules (usually, (Present Simple or Present Perfect tenses are used in the academic field), etc. If you doubt in any issue, rely on a real professional in proofreading than to struggle with it alone. For the better results in proofreading and editing your research paper, you should: Set your paper aside between the writing and proofreading processes. Spend a day without even looking at your paper. But it doesn’t mean that you should wait until the last minute to revise your research paper. Evaluate the overall content of your paper. Don’t correct immediately after you read a sentence or two ones. Sometimes, it happens you read a part of a sentence, start to rearrange it. However, when you read to the end, you realize the whole structure. Focus on what you need to look for. You should identify common mistakes often made by you or your groupmates. For example, if you know that the usage of articles is your weakness, look closer at the cases of their usage in your work. It is always easier to speak about the writing process on research papers than to do it. Right? But there some researchers who achieve a lot on Computer Science by having written readable research papers that are included in top 10 research papers on Computer Science by Mendeley readership. At least, after reading our computer science research paper guide, you can look at the great papers and create your own research paper on Computer Science so that the others similar to you will read it. Good luck!

Portfolio Diversification and Markowitz Theory Essay

Portfolio Diversification and Markowitz Theory - Essay Example However, there is a claim from Swisher & Kasten (2005) that a post-modern portfolio theory factoring in the role emotions and subjectivities has emerged but the leading journals do not confirm the claim. Gitman & Joehnk (1996, p. 670) attribute to Harry Markowitz, a trained mathematician, the development of the first set of theories â€Å"that form the basis of modern portfolio.† Modern portfolio theory is â€Å"an approach to portfolio management that uses statistical measures to develop a portfolio plan† (Gitman & Joehnk 1996, p. 670). Other than Markovitz, â€Å"several other scholars and investment experts have contributed to the theory in the intervening years† (Gitman & Joehnk 1996, p. 670). Gitman & Joehnk (1996, p. 671) identified that some of the key concepts used by the theory â€Å"are expected returns and standard deviations of returns for both securities and portfolios and the correlations between returns.† Gitman & Joehnk (1996, p. 673) point ed out that at the theoretical level, the optimal portfolio choice is made by an investor at the point of tangency between the investor’s indifference curve and his or her efficient frontier of investment. The efficient frontiers of investments consist of a set of combination of risks and returns deemed most acceptable to the investor. The investor is assumed to accept higher risks provided returns will be higher. This is shown in Figure 1 where the Is are the indifference curves of the investor associated with the investor’s utility. Figure 1. Indifference curves, efficient frontier, and optimal portfolio.

Numerical Problem - Speech or Presentation Example Further, the firm has a higher debt-to-equity ratio which is also unfavorable indicating more risk because the firm depends more on external lenders. Average collection period indicates the number of days a firm requires converting its receivables into cash. The firm takes more days that the industry average implying that the premiums receivable of the firm are less liquid or are converted less quickly into cash. The firm is, therefore, less efficient in managing its premium receivables compared to the industry average. Days cash on hand shows the number of days of operating expenses that the firm could meet with its current cash available. The company is in a worse situation because it has a lower ratio than the industry average and should increase its fundraising or cut back its spending. Return on assets is a profitability ratio measuring how efficient a firm is in using its assets to generate revenue. The firm has a higher ratio than the industry average implying that it is more efficient in using its assets to generate revenue than the industry average. The firm has higher TIE ratio than the industry average. It, therefore, has higher ability to meet its interest payments on the debt. The firm has a lower fixed asset turnover ratio meaning it is not using the assets optimally. It is less efficient than the industry average in using assets to generate sales or

Australian Government Innovative Climate Change Policy Essay

Australian Government Innovative Climate Change Policy - Essay Example It will mean that the equivalent of 20 per cent of Australia’s electricity will come from renewable sources by 2020 is transformed. The world is moving forward and economies which do not start cleaning up now will fall behind. Australia has spent the last decade working out on how to put a price on carbon pollution is the cheapest way to tackle climate change. The Government’s plan for a clean energy future has been negotiated by the Multi-Party Climate Change Committee. The Committee has agreed to a comprehensive set of measures to help fight climate change. The Government is separately investing in further measures to ease the economic transition to a carbon price, as well as taking additional steps to reduce carbon pollution. BACKGROUND AND ESSENTIAL IDEAS The Government has developed a comprehensive plan for a clean energy future. The need for this plan is clear, from both an environmental and an economic perspective. This plan has been devised in response to clear scientific advice that the world is warming, that carbon pollution from human activity creates. Significant risks and those we can avoid the worst potential impacts by reducing carbon pollution. Taking action on climate change is in our national interest. Australia faces acute risks from climate change. Faced with the serious negative consequences for our natural systems (including national icons like the Great Barrier Reef and Kakadu), our economy and our way of life, it would be irresponsible not to play our part in international action on climate change. Taking action sooner means that the transition to a clean energy future can be more gradual, manageable and...This paper outlines the positive effects of the comprehensive climate change policy, maintained by Australian government. More specifically, the paper describes the impact of Federal Government’s Clean Energy Bill, which was enacted in 2011. The Bill introduced carbon pricing mechanism designed to improve environmental and economic efficiency. In addition the energy bill contained innovative mechanisms to shield it from political and administrative cycles. Climate change will not just damage the natural environment. Left unchecked, it also poses risks to Australia’s economic prosperity. Within the purview of the Bill, all businesses will be required to pay for their pollution under this price mechanism. The carbon price will be beneficial to the economy since it will create a financial incentive that will flow throughout the economy. Households will benefit from tax cuts, higher family payments and increases in pensions. The carbon price will also change Australia’s electricity generation by encouraging investment in renewable energy like wind and solar power and the use of cleaner fuels like natural gas. The government will be committed supporting jobs throughout manufacturing, food processing industries and coal mining since The Government’s Renewable Energy Target, combined with the carbon price, will deliver around $20 billion of investment in renewable energy by 2020 in today’s dollars. It will mean that the equivalent of 20 per cent of Australia’s electricity will come from renewable sources by 2020 is transformed. Under the Government’s clean energy plan, the carbon pricing mechanism will establish a clear price path into the future for reduced carbon pollution.

Causes of Construction Site Accidents

Causes of Construction Site Accidents The construction industry is not only known as an industry which is developing rapidly but it is known for its highly dangerous activities as well. In Malaysia, hazardous works on construction sites that cause accidents are taken as a crucial matter. Every single year, construction workers are among the people who are always to get caught in accidents. This serious problem has caused them to involve in fatal injuries and some of them also have been killed. In the past few years, the construction industry has gained a lot of profits by buildings that have been constructed using latest advanced technologies, but somehow the safety measures on site still being neglected. Despite of delays of the construction progress and difficulties in repairing of works and machineries that cost lots of money to be spent, but of these are incomparable to the loss of the human life. The implementation of a proper and effective health and safety policy on construction site is very essential for a builder. The hazards must be clearly understood by all the personnel working on site especially those who hold a high position in a project. Proper commitment and attention by every personnel can help in reducing hazards and accidents in the working environment other than knowing their own responsibilities on site. Every party in the construction industry also should put safety measures as their main priority during the preliminary stage until the completion of a work or construction project. The construction industry is often portrayed with negative images such as dirty, dangerous and difficult or commonly known as the 3D. Whenever a construction related matter is being discussed, people will have these thoughts embedded in their minds. This will make people feel uninterested to be involved or working in the construction field and finally resulting in lack of workforce in this industry. Thus, the safety measures on site need to be improved in order to eliminate this mindset and to achieve a safer working environment. Each party also needs to make drastic actions in ensuring an effective safety and health measures are being practiced on site to preserve the good image of the construction industry in the future. 1.2 Problem Statement The standard of safety measures in construction industry in Malaysia has lagged behind if compared to any other industries. This scenario makes it hard to achieve zero accidents and developing a safety culture among the personnel working on construction site. In the real construction practice, it was found that the safety program implementation by majority of construction companies were only at the early stage. This clearly shows that these companies do not have a safety program driven by a safety culture (Abd Hamid Abd Majid, 2006) Although a lot of contribution to the national economy comes from construction industry, the number of accidents, incidents, injuries and fatalities are still reaching a higher rate (Hinze, 1997). For some employers or clients, the implementation of safety management system is often believed to cost more in a project and they make it as a less concentrated matter on construction site. This is why safety records are often being focused because of its unsatisfactory performance due to safety being neglected and has not been taken systematically. Safety aspects are considered very crucial especially in a construction project but unfortunately there are still many employers do not feel that it is one of the keys to the success of companies. It is also known that the nature of the construction industry requires physical demand and harsh works, make it an industry with higher risk of injury other than the lack of awareness on the responsibilities of each parties involve in a project to mai ntain the safety performance. Hence, the implementation of safety measure should not be taken lightly as it is an important element in keeping the construction site a better and safer place to work. In order to decrease the jobsite risk and improve safety measures, this research will be carried out to identify the common causes of accidents that contributing to the high rate of accidents on construction and to emphasize on the roles and responsibilities of parties involved in this industry. Research Aim and Objectives 1.3.1 Aim The aim of this research is to know the significance of practicing and applying safety measures so that it can create awareness to the people who are working in the construction industry especially the management on how safety plays an important role in reducing accidents on site. 1.3.2 Objectives The three objectives are to be achieved in this research are listed as below: To study the various causes of accidents that occurred on construction site This objective is to find out the causes of this problem so that it can be solved from the root more easily and efficiently. To assess what are the roles and responsibilities of each parties in construction industry on improving the standard of safety on site and how they can reduce the number of accidents This objective is to know the relationship between their roles and responsibilities with safety performance and how it ensures the site safety is implemented. To find the ways to improve the site safety practice involved in the construction site in Klang Valley. This objective is generate ideas, ways and methods to improve the safety measures on site 1.4 Scope and Limitation of Study This research will only focus on the construction sites based around Klang Valley. Areas of study are limited to identifying the causes of accidents on construction site like unsafe equipment and machineries, job site conditions, human factor and others. Besides that, a study on the roles and responsibilities of various parties involved in the construction industry will also be done. The parties to be included in this study are from the paymaster of a project or the employer and up to the professional bodies of this industry such as Construction Industry Development Board (CIDB). 1.5 Research Methodology In order to gain data for this research, various methods to extract necessary information regarding safety and health measures in the construction industry will be done. The information gathered is used to assist in the understanding of the causes that lead to the effectuation of accidents on construction site and the roles and responsibilities of various parties in the construction industry. The methods that will be used for this research are surveys, literature review and analyzing the information. Stage 1: Topic selection In this stage, the first matter that needs to be done is to identify problems occurring in this industry. Problem which is popular and most frequently arise will be chosen as the research topic. Then, literature review based on the topic selected is carried out by getting information from the previous research done by other people. Stage 2: Study proposal During the second stage, determining the aim and objectives of this research is important. It allows the research to achieve the target so that the main problem can be solved and eliminated. Besides that, the scope of the study is also specified to let the readers know the area of study that will be covered and not to be covered in this research. Stage 3: Data gathering and processing Primary Data In order to get practical information that can contribute to this research, surveys will be conducted. Survey questionnaires will be distributed to personnel working on site such as project manager, safety officer, site supervisor and others to get valuable insight into the risk and hazards involved on construction site. A practical view from them is of utmost importance to obtain information which is not available in books. This is also an opportunity to interact with the people involved in the construction field. The information that need to be obtain in the survey are like the causes of accident to happen in the construction site, what accident cases are often being reported and the role and responsibility of each parties to improve the site safety in construction. Secondary Data Secondary data can be obtained by finding sources and information in a library. Some of the libraries that will be the place to conduct this method are the library in Tunku Abdul Rahman College and the public library. The sources that will be used in the library are articles, textbooks, journals and magazines. The authors name, year of publication, title, place of publication and publisher of the book will be indicated in the research for referencing purpose. Internet is also one of the best sources to get information about safety on construction site. Relevant materials and information can be easily obtained in the internet because the application is wide and unlimited. Information such as statistics of accidents occurred on site and latest news on the construction safety and health issues also may be obtained from internet searching. Chapter II CAUSES OF CONSTRUCTION SITE ACCIDENTS 2.1 Introduction On the construction site, workers are exposed to hazardous works and dealing with such works everyday is something common for them. Safety First is a very popular phrase that can be found on most construction site but it does not being put under first priority as it is stated in signboards and posters. There is no wonder why the accident rates on construction sites are getting higher each year. Statistics also have proven that the number of deaths caused by accidents in construction industry has surpassed all other industry. The chart below shows the number of victims involved in death cases that have been investigated by the Department of Occupational Safety and Health (DOSH) up until December 2010. In this chapter, identifying the various causes of accidents will be the primary objective as it helps in generating ideas in improving safety measures on site. 2.2 Definitions 2.2.1 Accident Accident can be defined as an unplanned, uncontrolled event which has led to or could have led to injury to people, damage to plant, machinery or the environment and/or some other loss. The controlling of work situation by providing safe conditions and insisting on the use of safe working method and procedures is the way of accident prevention. 2.2.2 Hazard Hazard is a source, situation or occurrence in the workplace that has the potential to harm the health and safety of people or to damage plant and equipment. The situation could involve a task, chemical or equipment used. 2.2.3 Safety Safety can be defined as the quality of being safe and the freedom from danger or risk where people are protected against physical, occupational or other types of harm, error, failure, accidents or any event which is non-desirable. The controlling of hazards to achieve an acceptable level of risk also can be the definition of safety. 2.3 Unsafe Acts and Conditions 2.3.1 Unsafe Acts Usually, accidents at work occur either due to unsafe acts and unsafe conditions. There is no general agreement on the definition of an unsafe act. However, it has been defined in similar focus on unaccepted practices which have the potential of producing future accidents and injuries. Other definition of unsafe act that given by previous researcher is unsafe act is an action deviates from generally recognised safe way of doing a job and increases the chance of an accident (Stranks, 2000). Unsafe acts can be classified into two types either as errors or violations (Reason, 1990). According to most accident reports, the errors are to be found as a major contributor to accidents. Meanwhile, violations are less common. There are two conditions where unsafe acts may occur. Firstly, workers do not know while they are acting unsafely. Secondly, they know while they are acting unsafely. For the first situation, the problem can be easily solved by providing safety training to the worker, supervise them closely, providing good work system design, etc. The reasons for the workers to act unsafely for the second case is more complex because it could be due to various factors like personality of the workers, influence by coworkers, the extent of managerial support and the nature of the job being undertaken. Although workers are fully aware that they are working unsafely, they still want to carry on with such unsafe acts. There are various acts that are considered unsafe. Those acts are: Working without authority on the job can cause accidents since unauthorized workers may lack of skills and unfamiliar with the job process. Failure to secure coworkers or to warn about the danger is an unsafe act because many accidents occur while workers are paying less attention to warn and secure coworkers who are exposed to accidents occurrence when working. Working at improper speeds, exceeding the prescribed speed limits or unsafe speed actions could cause accidents. Not placing and stacking the materials properly in dangerous locations will cause unpredicted accidents to happen. The usage of tools and equipment, hand tools, power tools and machinery which is done inaccurately may result in accidents. Executing work by using defective equipment and tools. Refusing to wear personal protective equipment (PPE) will increase the probability of getting injured. Smoking which creates sparks in areas where flammable materials are stored could cause explosions. Throwing or accidentally dropping objects from high levels could expose other workers being struck by the object and cause head injury. Improper posture for tasks like workers making shortcuts by climbing or jumping from high levels instead of using ladders. Servicing equipment which is under operation. 2.3.2 Unsafe Conditions An unsafe condition is a condition in which the physical layout of the workplace or work location, the status of tools, equipment and material violate the safety standards. Some examples of unsafe conditions include open sided floors, defective ladders, improperly constructed scaffolds, protruding ends of reinforcing rods, protruding nails and wire ties, defective equipment, ungrounded electrical tools and many others. In most accidents occurred on construction site, unsafe conditions are the main cause contributing to an accident. It is distinguished that that unsafe conditions are divided into two types according to when they occurred during the sequence of work and who caused them to exist and develop (Abdelhamid Everett, 2000). The unsafe condition may exist in different situations which are before an activity is started and another one is develop after an activity is started. The occurrence of these two types of unsafe conditions is due to some other causes like actions and inactions by the Management Team and worker or coworker unsafe acts. 2.3.2.1 Actions and Inactions by Management Team Among the example of Management Team actions and inactions that lead to unsafe condition on site are they fail to provide proper and adequate personal protective equipment to the workers, fail to maintain or safeguard tools and equipment, violating the workplace standards such as ignoring slippery floors that can cause someone to fall, insufficient ventilation leaving the workers to choke, poor housekeeping and others. Workers are also sometimes requested to perform tasks that exceed the human capabilities or violate the human factors, ergonomics and the principles of industrial hygiene. This request which made unintentionally by the Management Team will expose the worker to unsafe condition of the site and eventually leads to injuries and illness. 2.3.2.2 Coworker Unsafe Act Inexperienced worker or coworker in working on the site will tend to act unsafe when handling a task which may lead to unsafe conditions for other workers. Unsafe condition will exist when these inexperienced workers doing their job recklessly like removing machine safeguards, working while intoxicated where they are under the influence of drugs or alcohol, working with less concentration due to insufficient sleep, neglecting the housekeeping rules, executing works where they do not have the authorization to do so, etc. 2.3.2.3 Site Layout Poor site layout in construction site is also contributing to the unsafe condition factor. It was reported that insufficient working space was a problem in a number of accident studies (Hide et al., 2003). Sometimes, the commencement of the build prior to the completion of demolition is blocking the space allocation on site resulting in number of reorganizations of site layout to fulfill the changing of the build plan. Other than that, space constraints can restrict the allocation of floor area for workshop placement, footpaths, storage, parking provision and adequacy of space transport routes. This will cause constriction to the room for vehicle to access the drop-off points and effect on the traffic flow on site and interrupt the ease of receiving deliveries where it leads to a subsequent need for double handling materials. It also will make the routes to become narrow and may cause accidents where vehicles can overturn and hit the workers in the surrounding area. 2.3.2.4 Ground Conditions Ground conditions are one of the risk factor for accidents. The common problem that is always found is raised structures on the walking surface that can create trip hazards. Some examples of trip hazards are electrical cables, ply board used as a temporary manhole cover and raised setting out points. It is hard for the workers to be aware of these hazards because most of the time they were coloured black, grey or brown instead of being marked or coloured. 2.3.2.5 Poor Housekeeping Good housekeeping is upmost the important thing to be considered to ensure the site is safe. Unfortunately, many sites found these days did not put housekeeping into their priority. Everyone on the site must do their part to ensure that the site is clean and orderly. Although, there are workers that felt that clearing up the site is the responsibility of other people who had created the mess or up to the Contractor to undertake it. This situation will make good housekeeping hard to achieve. As we know, the most common types of injuries that occur on site are slips, trips and falls which are also contributed by poor housekeeping. Accidents happened due to unorganized material will result in workers suffer cuts from materials and materials fall down striking workers head resulting in head injury. 2.4 Accidents by Equipments and Machineries On construction site, workers are required to use different types of equipments and machineries to ease the work that need to be done. By using these equipments every day, workers tend to put themselves at great risk for injury when they are using construction equipments. The equipments also can be defective and will cause the person using them or another person on site to be injured or killed. The defective equipments and machineries are required to be immediately tagged to indicate that they are damaged and remove from the construction area. However, the tags will sometimes come off and workers will not usually stop to walk away from their working area. Finally, someone may pick up and use back the defective equipments or machineries that make them involved in accidents. 2.4.1 Scaffolding The usage of scaffolding is essential in a construction project to get workers to a higher level of the building structure when they are executing a work. As much as it is useful to workers, it is also very dangerous and hazardous. Statistics reported that 28% of the accidents involving scaffold are caused by construction deficiencies. Among the deficiencies happened are because of the usage of substandard components, omitting essential components and failure to complete the assembly of scaffold. (OSHA, 2003). The people who are exposed to the scaffolding hazards are the ones who erecting the scaffold themselves, the workers that are going to use it when doing works and the general public near the scaffold. Scaffolding accidents usually will involve either people falling, incorrect operating procedures, environmental conditions, the scaffold collapse and/or people being struck by falling objects from the scaffold itself (Berry, 2011). There will be objects that fall to the ground because workers who work using scaffold will bring along some of equipment together with them such as paint and other related supplies, tools like hammers, screwdriver and also widow cleaning equipment. When there is a worker on the scaffold, it will not only cause harm to that worker but also to those who are on the ground with serious injury by getting hit by the scaffolding or other falling objects. Scaffoldings are usually kept outside which exposed to the environment. This can cause the scaffoldings to deteriorate. Scaffolds are often being reported to be in good condition by inspection and maintenance before they collapsed. This is because it is hard to detect corrosion of the internal surface of tubular scaffolds. Other causes of accidents of scaffoldings are: Unsecure scaffolding Poor or careless construction Use of poor quality of damaged material Missing or malfunctioning brakes Missing or malfunctioning fall safety systems Lack of or poorly conducted safety inspections 2.4.2 Crane The usage of crane is one of the major causes of fatalities during constructing a building and accidents often happen when lifting operation is executed. The occurrence of fatalities during crane operation still continue to increase although ongoing research and recommendations to reduce this problem have been done for the past several decades (Beavers et al., 2006). The most common types of crane accidents involve the crane coming into contact with electrical power lines. Overhead electrical power lines present a serious electrocution hazard to workers on site. The most common means of electric power transmission and distribution is the overhead line which normally made of uninsulated conductors supported on tower or poles. It is likely to come in contact with a crane because it is placed in a high position. When a crane is contacting with energized overhead line, it becomes elevated to a high voltage that can cause harm to the crane operator (Sacks et al., 1998). Severe injury or death from electrocution is the risks that need to be faced by the operator and anyone standing nearby if this catastrophe happens. The crane rigger also can contribute to an accident. Workers or bystanders are exposed to rigging crane accidents when the material connected to the load block or headache ball fall onto them. Besides that, heavy loads that exceed the limitations and stability of a crane will result in structural failure, causing the crane to tip and collapse over the operator and other workers below it. 2.4.3 Excavator The massive size, weight and power of an excavator will place an operator or workers at high risk of serious injury when there is an accident happens caused by excavator. The most common accident caused by excavator will involve quick-hitch. A quick-hitch is device used to make connection and removal of attachment such as buckets and rock breakers of the excavator. The risk arise from the quick-hitch is the disconnection of the attachment resulting works to be loose and falls from the excavator (Edwards, 2007). This incident can cause crucial injury or even worst, death, if the attachment such as heavy buckets are detached and fall onto the workers nearby. Other causes of quick-hitch accidents that involve unintentional release of the attachment are: the failure to engage the quick-hitch properly due to carelessness failure to use any secondary locking device poor maintenance of locking mechanism attachment being overloaded. Even though the cause of an accident can be obvious at first, there are also some root causes of excavator accidents that need to be identify such as: lack or inadequate training given to the operator inadequate supervision by supervisors during excavation works are executed poorly trained ground workers workers encroach the excavator operating area while it is working 2.5 Poor Management System It is necessary to have a good management system in a construction project as it can generate an organizational setting in which workers will be trained and motivated to perform safe and productive construction work. Unfortunately, many management systems fail to be responsible in creating outline procedures to identify and eliminate hazards and eventually letting personnel involve in undesired accidents. 2.5.1 Poor Safety Policy Nowadays, it is common to see Site Management not establishing an effective safety policy. Safety policy is important in a construction company stress on the principles and goals to show the companys commitment to workplace health and safety (CSAO, 1993). Less awareness on the importance of having safety policy is why there are big numbers of management did not implement it. When there is no effective safety policy made by the management, personnel on site tend to execute their work in a dangerous way because they do not have a proper guideline in safe working methods which may lead them to be exposed to risks and hazards in the construction site environment. By not having a safety policy, accidents that occurred will not only harm the personnel, but it will make the company bare a high financial risk. This situation is likely to happen because the management fails to provide support for safety programmes where it is considered as a need since an accident were proved to be costly. A better safety performance is also hard to achieve because management system does not have the responsibility to provide a safe work site for all personnel because the key in achieving that is to have viability and participation by the management (Sawacha et al, 1999). 2.5.2 Poor Organising Among all of the functions safety management, the most important one is to designate individual with responsibilities so that the construction safety programme and plan can be implemented successfully. Without having a well planned organisation, the management will find it hard to execute monitoring on policy implementation, to determine the roles of safety committees and safety representative, and to portray health and safety responsibilities in every individual job descriptions. The unsatisfied involvement and commitment by both management and workers also makes the safety policy to be less effective (Holt, 2001). Undertaking fault and correcting action being taken can hardly be done causing less improvement to the safety performance because the safety representative is also not well-trained due to poor organisation (Sawacha et al., 1999). The safety performance will only be at the same level without any improvement when companies with poor organisation fail in providing effective safety committees where they play a positive role in this matter (Sawacha et al., 1999). 2.6 Other Factors 2.6.1 Personal Factors 2.6.1.1 Laziness Taking shortcuts in doing works that being assigned are done by most workers because they want to avoid extra activities (Hall, 1995). Sometimes, workers feel that it is troublesome for them to choose the right tool during work so it is preferable to them to work with the wrong tools. 2.6.1.2 Past Experience For workers that have been working in a company for a long time and having to perform a similar job, it is hard for them to change or give up the way they do things. This is actually not recommended because the old habit can increase the possibilities of accidents to happen by preventing them from noticing the hazards (Kittleson, 1995). 2.6.1.3 Doing Works in a Hurry Sometimes supervisors want the works to be done as fast as possible which gives pressure to some workers and leading them getting the works complete in a hurry. In order for the workers to save time finishing the works, he or she may abandon the good safety practices (Stice, 1995). 2.6.1.4 Being Angry Angry is sometimes uncontrollable and makes someone not to be caution, leading him or her to be involved in accidents. To identify when someone is angry is by noticing that person is sweating, tremble and grinding the teeth. Anger that cannot be resolved will cause distraction, proneness to accidents, anxiety, rage and violence (Kittleson, 1995). 2.6.1.5 Overconfidence Having confidence is important for every worker and it is a good thing, but overconfidence can bring more harm than good. A person with an attitude of thinking that he or she will never involve in an accident will lead to wrong procedures or methods and cause injury (Hirsch, 1998). 2.6.2 Job Factors 2.6.2.1 Work Overload Workers can develop high stress especially when they are asked to do works more that what they could handle together with the pressure due to deadline. Work overload can be divided into two different forms which are quantitative overload where workers are asked to do more works, and qualitative overload where the workers lack of belief that they do not have the skills to get the work done (Greenberg Baron, 2000) 2.6.2.2 Work Underload Stress can also arise when someone is being asked to do too little work. There are two types of work underload which are quantitative underload where a person feels bored from having little work to do, and qualitative underload where a person is lack of mental stimulation like routines and repetitive jobs (Greenberg Baron, 2000). 2.6.2.3 Time Pressure Workers will get overwhelmed and worry once they felt that they are unable to finish a work before the deadlines (Stranks, 2000). Moreover, when there is a change in the work process and workers are not given sufficient time to complete it, they will easily become stressed.

The Effect of Divorce on Childrens Learning and Behavior Essay

The Effect of Divorce on Children's Learning and Behavior The effect of divorce on children?s learning and behavior is a major problem in today's society. Everyday, children everywhere deal with this issue. Nowhere is this displayed more prevalently than in our schools. Divorce hurts children more than parents realize. By the time they turn 18, approximately fifty to sixty percent of all children in the United States have been affected by divorce (Miller, 1). Divorce-related problems (e.g., visitation, child support, parental custody) can be ongoing sources of stress to children, even up to eight years after the initial separation. Children can be robbed of a special experience and protection called 'Family'. They move on in their lives as individuals without the understanding of what familial security and bond is. Children look out into the world and wonder why it has dealt them a cruel card in life. 'Why me' Why can?t it be Tim, the big bully. Surely he deserves it more than I do?!? (Ng, 1) There is a world of a difference between what one experiences in a healthy family versus one that is broken. The children of a broken family often feel rejected and or responsible for his or her parent?s breakdown in their marriage. When in reality, they are not, the parents are! Even if the child was a source of stress, it is the parents responsibility to find a way to deal with it. Besides rejection and guilt, children often feel abandoned by the two closest people in their world. It generally leaves scars that are difficult to heal. The child is left trying to understand why these two people cannot stay together and may even personalize the blame because they feel that they are not good enough to bring them back togeth... ...and self-regulation. Possibly the most important thing we can do is act as resources for the children. We have to try to ensure the success of the child and thus shape the future of mankind. References Leo, John (2000).
