Applied Econometrics - Assignment Example causes a reduction of median housing price by 0.028 in the first variant, a reduction of 0.027 in the second variant, and a reduction of 0.027 in the third variant. In the third variable, nitrogen oxide concentrations in parts per hundred million (NOX), the coefficients are 1.479 and 1.529 in the second and third variants respectively. These figures suggest that 1 percent change in nitrogen oxide concentration increases the medium housing price by 1.479 in the second variant and by 1.529 in the third variant. Beta coefficient is the measure of the sensitivity of the estimates in influencing the median housing price. In the estimates, the beta coefficient is the slope of the model summarized into ÃŽ ²0, ÃŽ ²1, ÃŽ ²4, ÃŽ ²3, and ÃŽ ²2. Normally, the coefficients would imply 1 percentage change in the estimate 1 and 2 would cause an increase of 0.566 and 0.0261. However, using the beta approach, the two coefficients are below, suggesting that they are below the median housing price. 6. Suppose in model (3) I added in the variable NOX DCHAS, resulting in ln(MVi) = ÃŽ ²0 + ÃŽ ²1RMi + ÃŽ ²2 ln(DISi) +ÃŽ ²3NOXi + ÃŽ ²4DCHAS;i + ÃŽ ²5 NOX DCHAS +Æ i . How would the interpretation of Æ 3 change in model (3) after the inclusion of this variable? What is the interpretation of Æ 5 in this model? 9. Given that the BP and White tests yield the same conclusion regarding the presence of heteroskedasticity, does this imply that the BP test is as good as the White test? Explain your reasoning in detail. Heteroskedasticity implies to the circumstance when the variability of a variable is unequal across the range of values of a second variable that predicts it. In this circumstance, it means that the Bp test is as good as the white test since in the presence of heteroskedasticity, it is expected to be different for variability, which is not the case. Heteroskedasticity does not necessarily imply an error, but only imply variableness, i.e. variability of a variable is unequal across the range of

The classical economists Essay Example | Topics and Well Written Essays - 250 words

The classical economists - Essay Example He does make a clear explanation of how the market system does dictate the nature of the prices to maintain the competition. When the demands of any product are high, the price will always escalate. The tight competition nature of any partaker in the market prevents any society from being exploited by the sellers, as they have to maintain a relatively reasonable price. Market laws also provide a clear regulation of the producers’ incomes. A business that is fetching immense profits will tend to attract a large number of people. When there is an overproduction of the same product, the cost goes down. Adam also did foresee two critical laws that act to curb greed in the market, the law of accumulation and the law of productivity. Accumulating profits are useful in purchasing new labor and machinery. Profits may subside due to labor and machinery demands. Increasing the population of the workers again is likely to lead to shoot out of the profits again. All these laws were illustrative of the kind of life that did exist in England in 1776 (Heilbroner,

Diabetes and ways to prevent diabetes Research Paper

Diabetes and ways to prevent diabetes - Research Paper Example It will expound on these areas to bring out the real situation of diabetes in the world. More than 20 million people in the United States suffer from the diabetes disease, accounting for over eight percent of the whole population. Research has shown that there are three types of diabetes, where all of them have their own causes and occurrence. This disease affects all people regardless of their ethnicity, race, age and gender. With the high prevalence of diabetes in the modern society, it is important to gain knowledge about its causes to help in its prevention and control (1). The main causes of diabetes are either absolute lack of production of the insulin in the body or inability to process the insulin produced. The body requires energy to function well. It receives this energy in the form of starches and sugars, found in the foods consumed. The body produces the insulin, the hormone that changes food into energy (Cook, 2). There are two major types of diabetes. The first type of diabetes, type 1, occurs due to deficiency of the insulin after the destruction of the pancreatic b-cell islets. The type 2 diabetes happens due to insulin resistance or irregular insulin emission (Zimmet & Shaw, 782). Type two of diabetes accounts for 90 to 95% of diabetes cases. In addition, type 2 diabetes accounts for the recent epidemic outbreak of diabetes (Cheng, 2). In addition to type 1 and type 2 diabetes, there is exists the Gestational diabetes, which commonly occur during pregnancy. There are high chances of women who experiences gestational to develop diabetes type 2 after the pregnancy. The treatment of diabetes will depend on the severity of the disease (Case, 4). There are other unclassified types of diabetes caused by particular genetic imperfections of beta-cell function, insulin action, drugs or chemicals or diseases of the pancreas. These unclassified types of

Compare and contrast the effects of the First and Second World Wars on Coursework

Compare and contrast the effects of the First and Second World Wars on the international system - Coursework Example trend of the international system has had no parallel since creation Cantor and Land (1985); Tuttle (1988); Goemans (2000); Karsmakers (2003) and ; the combined effects of the two wars changed the shape of the international system than all other recorded wars in history combined. Kvasnicka and Bethmann (2007) believe that posterity’s perfect understanding of the similar and combined effects of these wars can be enhanced by making a holistic view on the effects these wars had on migration, global population sex ratio and labor availability, and world order. Each of these perspectives would now be looked in context to see how the effects of the two wars were similar on them. In his book An Illustrated History of the First World War, Keegan (2001) maintains that the world’s population knew an unprecedented trend in location and relocation during WWI. This location and relocation was usually from one country to another or from one city/town to another. Such movement was usually to flee from danger from one part of the world to another part of the world where danger was not so imminent. According to Keegan, such movement was ever feasible because, although this war was termed a world war, it practically did not involve all the countries of the world per se. Infact, some authors like Keegan himself, Banks (2002); Gilbert (2004) have persistently held that the first world war was a European war, arguing that the US role in the war was more of an arbitration or mediating one. So some countries remained neutral and were favorable destinations for people to move from war-torn countries like Germany, Britain, France and Belgium. Meanwhile, contributions from authors on the Second World War pointing to the same issue of migration abound. Karsmakers (2003); Kvasnicka and Bethmann (2007) and Cantor and Land (1985) revealed that the bombings of the second world war made people to leave their homes to seek refuge elsewhere more that in a y recorded period in history. Such

Family Strengths, Functions and Structure Coursework

Family Strengths, Functions and Structure - Coursework Example Family accord contributes to the strength of family since it allows for competency when dealing with conflicts within the family. Factors such as open communication, commitment, spirituality, and appreciation also contribute to the strength of a family. Cultural beliefs have resulted in the change in the functions of various families. For example, in my culture the role of the family is viewed as that of ensuring the family name grows hence decisions are made in terms of how they will impact on the family name and not how they will impact on family members such as children. Another example of how culture has influenced families changing their view on the functions of a family is where in some cultures children are groomed to take care of their parents. Family structure is what makes up the family in terms of membership. There are various types of family structures. A nuclear family structure is one that is traditional where it is comprised of a father, a mother and their children. A single parent family structure is where a family is composed of children with one parent either a father or a mother. Finally, an extended family structures is one where a family is composed of various relatives. For example, living with ones grandparents and parents contributes to an extended family. Early childhood programs play an important role in families in that they introduce the children to the external world enabling them to venture outside the comfort of their

Concept of health (dementia) Essay Example | Topics and Well Written Essays - 3000 words - 1

Concept of health (dementia) - Essay Example arteries in the Heart are responsible for carrying the pure oxygenated blood and when it gets narrowed down due to the building of fatty substances on its walls, enough blood is not pumped in and out of the heart. This leads to symptoms such as chest pain, shortness of breath and in extreme cases, it leads to Heart attack. Coronary Heart Disease is called by different names such as Coronary Artery disease, Atherosclerotic Heart Disease and causes a combination of symptoms. The most important condition caused is called Angina which blocks blood flow in heart. Limitation of blood flow in turn causes a condition called ischemia in myocardial cells. When myocardial cells starve and die of oxygen it leads to a condition called myocardial infarction and there will be numbness in the body which is called as paresthesia. This disease is of particular interest because in England alone it kills more than 110,000 people annually. The disease does not have a big history as it was discovered very late after many changes have happened to the eating and working habits of people. CHD is also the most important cause of death in the US where more than 15 million people have some form of this condition. Also, according to Guinness Book of Records, Northern Ireland is the country with the most occurrences of CHD in the world. CHD is not biased with gender affecting both males and females equally. Although men in the 40’s are more susceptible than women, it gets evened out because as women get older, their risk is equally high as that of men. From 1984, more women have died of this heart disease than men. Already one in three females die of CHD while one in twenty five females die of Breast cancer. Forty to Fifty percent of women older than 45 have high levels of Blood pressure called Hypertension and high levels of Cholesterol which are the well-documented risk factors of heart diseases while smoking is the most common and preventable reason for cardio-vascular diseases in

Effects of the use of web-based tools in Blended Learning Essay Example for Free

Effects of the use of web-based tools in Blended Learning Essay Technology has made a deep impact on all aspects of human lives ranging from communication to learning and enhancing individual performance. The conventional classroom is slowly being replaced by computer based training and online learning environments that has penetrated remote corners of the globe via the Internet. The use of information and communication technologies in education has transformed traditional methods of learning and teaching practices. The personalized learning environment offered by the online medium has great potentials and can influence the learning process to a considerable extent. Technology has been a great enabler of transforming and re-defining the way a system operates and the wide variety of applications that it can support. Many web based learning environments use innovative technologies that have revolutionized the learning process over the past few years. Distance learning through the use of collaborative tools and technologies available has made significant breakthroughs in the field of learning. In the past few decades a number of tools and technologies have emerged that has enabled the users to adopt distance learning courses and training departments are using it to provide cost effective means of implementing learning and development programs for their employees spread across the globe. The online learning environment is supported by various types of tools that provide high level of interactivity and collaborative features enabling participants to exchange messages, files, videos and presentations. This kind of technology is increasingly being used in a wide range of applications ranging from facilitating electronic discussion between students to enabling distance learning programs through web conferencing. The revolution in communication and information technology has had a profound effect on the teaching and learning process. The change is visible in developing learning communities online. Most of the countries and even developing economies are stressing on the use of computers as an instructional medium. E learning encompasses a wide variety of tools and technologies that can be used to stimulate the learning process in an individual. With the help of this technology a variety of online learning services are made available ranging from online searches, tutorials, college courses, and professional courses to professional training and individual development programs. The E learning model adopts high level of audio and video interaction integrated with graphics and animation tool to present the learning module in an attractive format. Educational institutions and business organizations are increasingly adopting the e learning model for learning and training purposes. E learning is being increasingly used as a solution for delivering online learning regardless of physical locations or time constraints. The whole world has become an increasingly connected global community that can share ideas and exchange information through the Internet. More people across the globe are turning towards the latest technology gadgets that have made communication channels smoother and faster. It has proved to be a big resource for individuals who would like to learn a new skill or train themselves in new fields while pursuing their current employment. Hence, E learning field has provided new and better learning opportunities extending its reach beyond university campus and corporate learning centres. Blended learning – an overview Blended learning has been described as a â€Å"phrase introduced by the distance learning community in recognizing the value of synchronous learning activities, like face to face interactions with instructors and collaborative work with peers, as complements to activities performed asynchronously by individual learners† (Howard et al. , 2006). The blended learning system includes both web based learning and traditional classroom learning environment. The web based learning system provides the students with self paced learning modules that they can pursue at leisure and convenience depending on their learning capacity. This learning environment also provides E learning tools that enable live discussions and online learning programs. The conventional classroom settings are used to clarify doubts and queries regarding the course content and student progress. An effective learning environment facilitates interaction between the learners that increases the scope to exchange ideas and opinions, share experiences and assess their level of understanding on the subject matter. A classroom environment provides this kind of face to face interaction enabling the students sharing the same learning goals to coordinate with each other, communicate their ideas and information. Jonassen (1988) has stated in his works that the effectiveness of any learning environment is based on the types and levels of cognitive and metacognitive activity engendered in the learners. It is widely accepted that learning is enhanced in instructional settings where students are engaged in processing personally relevant content and are reflective during the learning process. Learners that participate in active learning activities find learning a more pleasurable and increasingly effective than engaging in monotonous lecture sessions. Online learning provides the learners with the scope to explore the topics and study related theories that increase their level of understanding. The key ingredient to a successful computer based learning application is its ability to interact with the student and direct the flow of learning in accordance with the student capability. The visibility and presentation of information through attention grabbing graphics and multimedia tool make this a more effective learning platform. Once the attention of the student is on the learning tool the application needs to stimulate the learner’s curiosity that in turn leads to search for answers and in-depth study of the learning module. The most effective teaching method involves a high level of interaction between the teacher and the student. A dedicated teacher is one who understands the student’s learning capacity and his shortcomings and guides him through with effective feedback. A two-way communication between the teacher and the student is very effective in the learning process. Computer based learning applications are continually striving to achieve the human to human interactivity level and have been quite successful in this venture with the aid of multimedia based technologies. Blended learning combines the positive aspects of both conventional classroom learning and online learning to provide an enriching learning experience to the students. Web-based tools There are wide varieties of computer-mediated communications technologies that enable manage and support E learning. These tools have facilitated extensive collaboration and communication protocols providing an enriched learning environment. Some of these tools are email, chat, video conferencing, web conferencing, newsgroup, blogs, forums, virtual classrooms, and message boards. Synchronous and Asynchronous tools â€Å"E learning is commonly referred to the international use of networked information and communications technology in teaching and learning. It refers to educational processes that utilize information and communications technology to mediate asynchronous as well as synchronous learning and teaching activities† (Naidu, 2006). Both synchronous and asynchronous tools can be used effectively to communicate, exchange and form ideas and information on a specific subject matter. Synchronous E learning is live, real time facilitated instruction, and learning oriented interaction that enables learners to use electronic means to collaborate and participate in live forums. The root of synchronous E learning has been derived from three main influences: the classroom, the media, and the conference. The virtual classroom uses highly interactive forms of synchronous E learning tools to simulate a conventional classroom environment. White-board, discussion rooms, and break out areas are some of the concepts used to enhance interactivity between learners in a virtual classroom. Naidu (2006) also observes that most of the applications are built around the synchronous learning model that makes use of tools like virtual learning environment, rapid E learning, web casting, web conferencing, video conferencing, webinars, live E learning, and e conferencing. These synchronous E learning tools help in connecting dispersed learners, facilitating real time interaction and collaboration, fostering a sense of immediacy and co-presence, developing a learning community, and enabling access to subject matter expert resources. This kind of learning environment rules out gender and personality dominance that tends to overpower in a traditional classroom setting. It encourages learners towards better teamwork, collaboration skills, strong motivation and extended peer support (Naidu, 2006). Asynchronous tools like emails, electronic forums, online discussions, blogs, provide a platform for students and teachers to discuss ideas and opinions on a specific topic. This form of E learning is â€Å"commonly facilitated by media such as email and discussion boards, supports work relations among learners with teachers, even when participants cannot be online at the same time† (Hrastinski, 2008). This provides a form of flexibility to the learners since they can access learning materials and information any time according to their convenience. The learners can log on to an E learning environment and access training materials, receive and send messages to peers and tutors. In higher education, learners can pursue online courses while taking care of other commitments. Asynchronous E learning tools have the advantage of enabling users to access information and pursue their subject matter with greater degree of concentration allowing the mind to process the information at leisure. However, it also has some significant drawbacks that include greater learner discipline since the learner has to take initiatives to login and make use of the information and tasks involved in learning process. This kind of learning process is more impersonal and isolated as compared to synchronous learning tools that enable live interaction (Ashley, 2003).
