Freshman Forced to Live on Campus Annotated Bibliography

Freshman Forced to Live on Campus - Annotated Bibliography Example The author of the article is credible and well aware of the trend, as she has been associated with the Arizona State University for more than three years (Soucie, 2009). The targeted audience of this article is the teacher`s faculty and students of the university, who are willing to know about current situation of campus housing (Soucie, 2009). Moreover, in this article it is explained that university students do not like to live in campus houses, but the reason behind their preferences is not clearly mentioned in the source (Soucie, 2009). Villagio apartments are most preferable houses of students and they so wanted to live in there, but due to economical situations, they cannot afford those houses (Soucie, 2009). Here, the author should mention the difference between rents of Tempe homes and campus houses, but he failed to do so. This article is useful and I will use this article as an important source for illustrating promotion of campus houses in the universities in comparison wi th other rental homes for students. This article is also taken from the same source. The title of the article indicates that the university is welcoming all new students to come and live in campus houses. The writer of this article is trustworthy and responsible because he is a qualified young journalist, who has recently passed out from the Arizona State University (Quizon, 2008). The author has targeted fresh students of the university and those who are willing to take admission in the Arizona State University (Quizon, 2008). The author has explicitly explained in his article that students, who live on campus houses, can have more chances to attain good marks in the exams, as previously it has been noticed that students who lived on campus houses performed more efficiently, than those who lived in other rental houses away from the campus (Quizon, 2008). Additionally, views and comments of faculty members show that campus intended to provide

environment is under constant threat as a result of modernisation

environment is under constant threat as a result of modernisation The environment is under constant threat as a result of modernisation, business activities, constant growth and development. All these are human activities that affect the immediate environment. The depletion in natural resources especially by the oil and gas companies such as the Pipeline Product Marketing Company (PPMC) has resulted in serious environmental impacts. Therefore, the need for sustainability and sustainable development cannot be overemphasized as it has become more important over the last two decades (Micheal Lan, 2000; Carbon Trust, 2008; Hahn, 2001; Cunningham et al., 2005). These accounts for the increasing pressure on governments to develop a response to a variety of problems which range from the use of natural resources to pollution control. In response, variety of environmental protection legislation and regulations were formulated with the aim of protecting the environment (Powley, 2004; IEMA 2005). The increase in natural resources consumption between 1961 and 1990 by 25% every 10 years resulted in serious environmental impacts in the form of acid rain. This leads to raising acidity in the soil and water thereby causing damage to forest crops, and freshwater fish and wildlife. Methane emission and mining waste, oil spills, air pollution by sulphur dioxide, nitrogen oxide and carbon dioxide as a result of burnt coal, oil or gas including climate change are also causes of environmental impacts (Micheal Lan, 2000; Edwards, 2000; Jaccard, 2005). PPMC is a subsidiary of the Nigerian National Petroleum Corporation owned by the Federal Republic of Nigeria. The company is involved in oil processing, production and marketing. PPMC was established to offer excellent customer services by transporting crude oil to the Nigerian three refineries as well as moving white petroleum products to existing markets. Its main objective is to profitably and efficiently market refined petroleum and petrochemical products in the domestic market as well as in the ECOWAS sub region and also provide marine services (PPMC, 2009). INVESTMENT PROJECT The PPMCs monitory and inspection department has 36 vehicles, a vehicle in each of the 36 states of Nigeria. The vehicles are used as official cars by staff in order to move in-between their offices, depot and filling stations and monitor and inspect their daily operational activities. Each car covers hundreds of kilometres daily due to the long distance between their office, filling stations as well as depots which are located far out of the city for environmental purpose. Every car consumes approximately 50 litres of petrol per day. However, it is environmentally unfriendly as they pollute the environment with carbon emissions. The company has set a target to drastically reduce or if possible to stop polluting the environment. Therefore, the senior management wants to accomplish a viable project with a length of 4 years, to improve their environmental performance and upgrade its corporate social responsibility. This project is expected to be a non-profit project that could bring ma ny savings to the company and return the initial investment in 3 years in order to avoid risk. The decision of expecting the payback period of 3 years was made by the senior management after careful consideration of the companys payback criteria which is 5yrs. PPMC has a standard of judging all its investments objectively, so as to determine whether the payback period is good or bad thereby passing an objective judgement as to know if the investment is worthy to be taken or not. Reducing or stopping the amount of petrol that is used during their daily activities, will support the company to obtain good corporate image and cost savings as each litre of petrol is N65 (Naira). In addition the company spends an average of N25, 000 monthly for maintenance on every car. PPMC is experiencing a great loss of resources as a result of this high petrol consumption every day there by polluting the natural environment. The vehicles have been used for approximately 6 years which has exceeded its guarantee period of 1 year. They are being used at maximum level as PPMC operates everyday including weekends and public holidays due to their nature of work and huge demand for their supply. The company is currently spending N52, 920,000 annually trying to main tain and fuel the old vehicles. The breakdown of these expenses is shown below: Annual cost of fuel and maintenance (Running cost). This includes running cost of fuel, repairs and monthly checks. Monthly cost of fuel = 50 x 36 x 30 x 65 = N3, 510,000 Annual cost of fuel = N3, 510,000 x 12 = N42, 120,000 Monthly cost of maintenance = N25, 000 x 36 = N900, 000 Annual cost of maintenance = N900, 000 x 12 = N10, 800, 000 Total Annual Expenditure = N42, 120,000 + N10, 800, 000 = N52, 920,000 In order to solve the above mentioned issues, PPMC management have decided to replace the old vehicles with brand new electric cars. These electric cars use neither petrol nor diesel, they have zero emission and their only by product is water. The car is known as Honda FCX Clarity, it is a Fuel Cell Electric Vehicle (FCEV). This vehicle has worn the world green car award, during the 2009 World Cars Awards in Newyork. This award has upgraded Hondas corporate image by exposing its commitment towards a green environment. In addition, Honda already has an excellent history of environmental leadership as they are known to be manufactures of low emission vehicles under an improved regulatory requirement (Honda, 2009). It is rated by the Union of Concerned Scientists (UCS) as the greenest auto maker for four different times in a row (UCS, 2007). The car generates electricity through the V flow fuel cell stack and stores it by the use of its highly efficient lithium ion battery, which helps recover energy. It also monitors electrical flow through its power drive unit and propels the vehicle (Honda, 2009). Honda FCX Clarity has an improved safety measures such as the Vehicle Stability Assist (VSA), Collision Mitigation Braking System (CMBS), six air bags and a unit body structure that is well reinforced. It also has a visual and audio alert which alert the driver in case of any potential collision. Another safety precaution programmed in the vehicle is the prompting of the driver by the automatic tug of the seat belt in case of an unavoidable accident it minimises the speed by breaking force to reduce the impact of collision. Furthermore, it has a very strong electric motor as well as groundbreaking new fuel cell stack. These safety measures have been tested by the United States Federal Safety Standards and it was a success story (Honda, 2009). The purchase of Honda FCX Clarity by PPMC will demonstrate the companys commitment towards the reduction of Co2 emission thereby protecting the environment. The company will also be recognised as the first to introduce zero emission cars to Nige ria and it will serve as a solution that could bring cost savings. Total cost of investment Number of cars to be purchased = 36 cars Cost of each car = N3, 000,000 Total amount to be spent on cars = N3, 00,000 x 36 = N108, 000,000 Cost of delivery (Shipping) = N300, 000 x 36 = N10, 800,000 Total cost of investment = N108, 000,000 + N10, 800,000 = N118, 800,000 Annual savings The investment is expected to save the annual cost of fuel and maintenance; N42, 120,000 + N10, 800, 000 = N52, 920,000 Since the vehicle also comes with a free maintenance package including running cost for 3years 6months in form of a guarantee, as it is a newly introduced vehicle. Honda Company is trying to advertise this environmentally friendly vehicle to the world and attracting customers by covering maintenance and running cost. This is better compared to the guarantee of the old vehicles which is only 1 year. N52, 920,000 will be saved in the first year, while in the subsequent years N1 per litre will be added due to the projected annual oil product price increment. Therefore the total cost of investment will save the annual cost of fuel and maintenance. It is important to note that N65 is the current price of the petrol in Nigeria. Investment appraisal is a technique used by managers to achieve their target. It is the duty of the manager to determine and prove the importance of the project (Akalu, 2001; Mulholland et al., 2003). Therefore, it is important in the planning of this particular environmental project. PAYBACK PERIOD The duration of time for the PPMC to gain its initiated investment of N118, 800,000 on implementation is known as the payback period (Layard Glaister, 1994). The period of time that cash inflows will become the same with cash outflows is also known as the payback period (ACCA, 2008). However, it does not consider time value for money which expresses that, amount saved today is much more valuable than the same amount saved in 2 years. This is considered as one of the greatest setback (Dury, 1997). Initial investment Annual savings Table 1 Payback period   Ã‚                                                            Cash flow                                              Cumulative cash flow Initial Investment                     (118,800,000)                                                (118,800,000) Savings Year 1                                                   52,920,000                                                      (65,880,000) Year 2                                                   42,768,000                                                      (23,112,000) Year 3                                                   43,416,000                                                       20,304,000 Year 4                                                   44,064,000                                                       44,064,000 Total savings                           N183, 168,000 Initial Investment = N118, 800,000 Year 1 and Year 2 savings            =         52,920,000 + 42,768,000 = N95, 688,000 Year 3 = N43, 416,000 In order to calculate the payback period with precision and accuracy, the year 3 savings should be broken down to monthly by dividing it by 12 and then the cumulative savings for year 1 and 2 should be subtracted from the initial investment. The result should then be divided by the monthly savings of year 3 to have the actual number of months (Mclaney, 1994). This is calculated below: Savings per month for year 3 = N43, 416,000/12 = N3, 618,000 N118, 800,000 N95, 688,000 = N23, 112,000/N3, 618,000 = 6.38 Approximately 6 months. Payback period is 2years 6 months   NET PRESENT VALUE (NPV) NPV is realised by using a discount rate to determine the current value of future savings and subtracting the capital cost (Hannagan, 2008). This method accepts with projects that have positive NPV. The method also makes comparison between present value of cash outflows and inflows from an investment (ACCA, 2008). The table below shows the number of years (4), future value (FV), cash flow, discount factor (DF) 15% and the present value (PV). The first step in calculating NPV is to multiply the cash inflow (savings) by the DF of each year to get the PV. Then, sum up the PV and deduct the initial investment from the total PV to arrive at the NPV (Mclaney, 1994). 15% DF was selected not to make profit but to avoid risk; it was selected after considering the current base rate of the Central Bank Nigeria which is 13.2% as the base rate keeps appreciating every year (CBN, 2009). Inflation rate in Nigeria increases, therefore oil product price will also appreciate.

INTERNAL RATE OF RETURN (IRR) IRR is a very important technique that influences the decision making as to whether or not an investment should be approved. It is interested in projects whose IRR are greater than the target rate of return. It also considers time value for money (ACCA, 2008). In order to have precision in calculating the IRR similar steps will be taken as how the NPV was sorted. However, it will require calculations at two different stages (NPV1 and NPV2) with two different DFs and normally both DFs should be greater than the DF used to determine the NPV. Finally the IRR formula will then be applied. IRR = NPV1 x (B A) + A NPV1 NPV2 Table 3: IRR calculation Years                           Cash Flows                DF (at 18%)                   PV Year 0                           (118,800,000)                      1.000                         (N118, 800 Initial investme-+nt) Year 1                               52,920,000                            0.847                                     44,823,000 Year 2                               42,768,000                              0.718                               30,707,000 Year 3                            43,416,000                            0.609                                     26,440,000 Year 4                               44,064,000                              0.516                               22,737,000 Total savings             183,168,000                                                                      124,707,000 NPV1 = 124, 707,000 118, 800,000 = + 5, 907,000 Table 4:  Ã‚                                 Years Cash flow                               DF (at23%)          PV Year 0                  (118,800,000)                                     1.000                                     (118,800,000) Year 1                                             52,920,000                                          0.813                                        43,024,000 Year 2                                             42,768,000                                          0.661                                          28,270,000 Year 3                                             43,416,000                                          0.537                                          23,314,000 Year 4                                             44,064,000                                          0.437                                          19,256,000 Total savings                         183,168,000                                                                                              113,864,000 NPV2 =      113,864,000 118,800,000 = 4,936,000 IRR calculation:                           Ã‚   5907  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  x (23 18) + 18   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  5907 (- 4936)   Ã‚                                                                                   IRR=20.7% NON FINANCIAL FACTORS The key purpose of an environmental initiative according to Sheldon and Yoxon (2003) is to reduce environmental impacts of an organisation in ways which makes business sense. The direct result of this provides organisations with benefits which include the use of alternative source of energy to increase in an organisations efficiency, thus providing the organisation with a competitive edge. In addition, it ensures compliance with environmental regulations and increases organisation understands of how its activities impact the environment (Brady, 2006). PPMC has a lot to benefit apart from the financial savings. The organisation will be contributing its own quota towards achieving sustainability. This will result in environmental performance improvement through the initiative of purchasing brand new cars to reduce or stop carbon emissions. The initiative will reduce pollution, minimise waste, protect the natural environment and provide better corporate social responsibility as well as good corporate image to the organisation. Furthermore, status of the companys reputation will be upgraded as it is encouraging green environment and legal compliance (Aslaksen Synnedstvedt, 2003). It will also assists in the implementation of environmental policy, while improving compliance with legislation and corporate image (Sheldon Yoxon, 2003). Moreover, PPMC will demonstrate good operations within a safe and clean environment thereby creating a friendly environment for staff and the public (Edward, 2004). This will help sort out social matters and improve health and safety. Since, the electric cars have a highly improved safety measures that could provide ways of pollution control to protect the people and their environment (Edward, 2004). The company could also benefit from changes within the organisation, by delivering this environmental initiative that deals with environmental impacts such as climate change and global warming caused by their emissions (Murray, 2003). In addition, it will support the company to identify and minimise its impacts on the environment so as to enhance its corporate social responsibilities through the use of an alternative source of energy. This will not only promote their business environment but will promote the global environment at large. Purchasing the zero emission vehicles will pave way for the organisation to achieve sustainable development since it is a strategy that could consider maximum utility of resources. In addition, the project is not aimed at profit making but returning of initial investment. SUGGESTIONS/DISCUSSIONS AND CONCLUSION. The rate of interest at which the investment cost leads to investment benefit is known as the IRR. This means that, all investment gains are with the time value for money and at the interest rate, the investment has a zero NPV (ACCA, 2008). This investment appraisal has demonstrated the use of IRR to value the cash flow and raise it as a consequence of the investment while determining it with inflation (ACCA, 2008). For example, a higher target rate of return was chosen, so that even in a situation where the inflation rate rises the company will still save cost. Interest rate may rise to 15% during the life time of the project due to the increasing inflation rate in Nigeria, as history has shown that Nigerian base rate rises up to 0.45 every year. Therefore, risk is incorporated and the project is considered less risky. The IRR is 20.7%, this has shown a very good risk margin considering the Nigerian economic instability. Furthermore, the advantage of the IRR being 20.7% is that, eve n if the interest rate increases the project will still be economically good. Base rate of the Central Bank of Nigeria was used to determine the cost of capital and calculate the initial NPV. The base rate was also used to incorporate inflation by discounting cash flows to get the future value. Inflation changes value for money, this is the main reason for using the base rate in determining the discount factor for the NPV calculation. Two discount rates were used to solve the equation of IRR which assumes that NPV changes with discount rate but this is not the case in reality. The positive result of the NPV means that the project should be accepted and the chosen discount rate of 15% helped identify the actual value of the savings to be made, based on the fact that the project is anticipated to make an overall savings. However, the actual value of IRR is more important as it considers the current economic climate and the future interest rate of Nigeria. The result has shown that the IRR is higher than the target rate of return. It is important to note that, ba se rate is used to determine NPV not IRR while IRR assumes that NPV is zero. The savings to be realised by PPMC as a result of the new initiative as well as the indication of an attractive Payback period upon investment is clearly exposed. Payback period 2 years 6 months is a good payback period since, the criteria requires payback of the initial investment in 5yrs. Hence, it would have been a bad payback period if it exceeds 5years. Furthermore, PBP was used to support other data because it is not enough to serve as criteria for investment. The company will continue to benefit from the project for years even after returning the initial investment. PPMC could consider using a different discount rate for this project since it is aimed at executing an environmental project and not profit making. This appraisal has been thoroughly evaluated and has proven that the investment is reasonable (Mclaney, 1994). Since, the company will spend only N65, 880,000 more on the annual maintenance cost (52, 920,000) and save N52, 920,000 in the first year and more in the subse quent years at the same time stopping the carbon emissions from the old cars. In addition, it is a mandatory for the company to meet up the governments requirement to reduce environmental impact and comply with the prevailing legislation. If the organisation was not to invest in this project the money would have been channelled to the federation account and budgeted to execute other projects in other sectors or Nigerian ministries. However, PPMC has the authority to use any reasonable amount to improve its environmental performance or execute any viable project that will be beneficial to the organisation. Finally, the calculation resulted in a less discount rate where NPV1 became positive and a greater discount rate where NPV2 remain negative and IRR fell in between the two discount factors (ACCA, 2008). The 3 investment appraisal techniques were fully utilised to determine the projects viability. This has proven that the project is economically viable (Mclaney, 1994). In view of this, the investment appraisal is affordable and worthy of acceptance. Moreover, the purchase of the electric cars is the best option, as it will not only reduce carbon emissions but will stop the emissions from the old vehicles completely, thereby upgrading the companys image as well as enhancing its overall environmental performance.

Organized Crime Wthin The Unit Essay -- essays research papers fc

Organized Crime Within the United States Organized crime is a widespread topic of concern among many Americans due to its popularity in the media and entertainment industry. The public is aware of its existence, yet is not fully aware of why and how this complex â€Å"underworld† exists. In order to fully understand this area of criminology, one must take into account the characteristics of organized crime, the variables that allow organized crime to thrive, its large-scale effects on society, and the measures that have been taken to extinguish organized crime. The roots of organized crime can be traced back to periods of vast amounts of immigration within the United States. Many of the immigrants sought wealth and prosperity upon their arrivals but inevitably found themselves to be members of the lower class. While some groups, such as the Jews, were able to climb the social ladder, other groups faced hostility and racism, hindering their acquisition of wealth. Their movement toward crime can be explained by Cloward and Ohlin’s Differential Opportunities Theory. This states that there are both legitimate and illegitimate means to achieve desired goals. In the immigrants’ case, they â€Å"want what American society offers and expects of all – success – yet they are prevented from legitimately achieving this goal because of opportunity blockage, that is poverty and discrimination† (O’Kane 27). In turn, the immigrants turned to a criminal subculture as means to attain their goals. They began violating an extreme amount of criminal statutes such as extortion, murder, bribery, fraud, narcotics, and labor racketeering. Thus far, the focus of this topic has been on early groups of organized criminals within the United States. The face of organized crime has changed within the past few decades, however, and is currently in a period of transition. Whereas the Italian-Americans were once the rulers of the underworld, African-American and Hispanic involvement has been on the increase. This cultural shift is significant because it alters the infrastructure of organized crime within the United States. Criminal groups form in different manners than in previous years. Within Italian-American organized crime, kinship is the primary segue into organized crime. Among African-Americans and Hispanics, however, there are two distinct types of linkages among criminals. First are causal... ...uently used by wealthy and large corporations, in order to monopolize† (Miller 1999). Although it appears as though many actions are being taken in an effort to extinguish organized crime, RICO illustrates that the government may have ulterior motives behind their efforts. If this is the case, the government must expect organized crime to increase according to the Differential Opportunities Theory. According to this theory, organized crime occurs when minority groups are unable to achieve the ‘American dream’ through legitimate means. By further oppressing these groups, the government places them back at square one where they will most likely continue to lead criminal lives. Thus the most effective manner to alleviate organized crime is to ensure that the aforementioned groups have access to legitimate means in achieving their goals. By making this effort, the government would have a greater chance of preventing the underclass’s development into the underworld.

Development /Diffusion of Early Human Societies Essay

The world’s longest river; The Nile, is considered Egypt’s lifeline. This significant physical geographic factor, has contributed to the development of the ancient Egyptians. This country which is located in Africa’s northeast corner, receives very little rainfall throughout the year. As a result, Egypt has relied on the Nile River for its economy. Each year, the Nile floods due to upstream rain, depositing a type of rich black soil called silt, along the river banks. The silt at the river’s mouth forms into a triangular shape, which creates a delta. Most of Egypt’s population clustered in the Nile’s river valley and delta. This river’s yearly floods made these regions so fertile that ancient Egyptians called their country Kemet, or the Black Land. (Bednarz, 2008) Ancient Egypt, one of the world’s first great civilizations, arose along the banks of the Nile. For centuries, geography kept Egypt isolated. Six high waterfalls calle d cataracts, and rapids make the Nile hard to navigate in the south. Desserts surround the Nile in the west and east, and the Mediterranean Sea borders Egypt to the north. People created farming villages along the Nile by about 4000 B.C. Eventually these villages became two kingdoms, Upper Egypt in the south and Lower Egypt at the Nile delta. The Nile Valley provided various grasses and reeds used for huts, sandals, baskets, simple boats, and other products. Ancient Egyptians also dug canals to irrigate their fields and channel the Nile’s water. Each June, floods would leave behind silt in a narrow strip along the flood plain and at the delta. Today, the Aswan High Dam controls the Nile’s flooding and provides year-round irrigation. Since the Aswan High Dam opened in 1970, Egypt has doubled its agricultural production. (Bednarz, 2008) Over the centuries, religions have spread from their points of origin to the rest of the world. All of the world’s major religions began in Asia, and moved to other continents. At first, religious beliefs were carried to different places by followers of the religion or traders. In some lands, traditional religions have been practiced for as long as people have lived in a culture group. The development and spread of beliefs by Egyptian religion, provides an example of the process of diffusion between early human societies. Ancient Egyptians worshiped several deities (gods or goddesses), and considered their pharaoh leaders to be earthly versions of them. During the New Kingdom period of Egypt, a pharaoh known as Akhenaton, promoted the worship of only one deity, the sun god Aton.

Edger Allan Poe essays

Edger Allan Poe essays Ssshhh! Whats that noise beneath the floor? Sound familiar, maybe you have heard this revised phrase from shows like, The Simpsons or Friends. That phrase came from The Tell-Tale Heart by Edgar Allan Poe, who was a write ahead of his time. He produced many classic books that are still read today, but like all authors he had to start from the beginning. Edgar Poe was born on January 19, 1809, in Baltimore, Massachusetts, to father Dave and mother Elizabeth Poe. Edgar had a brother, William Henry, and a sister, Rosaline. Shortly thereafter, his family moved to New York where his father, David Poe, resumed his acting career. David soon quit acting and abandoned his family. He died a short time later (Wagenknecht). Soon afterward, Edgars mother, Elizabeth, developed tuberculosis at the age of twenty-four and died, The image of his mothers young, still, white face was to haunt Edgar for the rest of his life (Wright). A young tobacco merchant and importer from Richmond, John Allen and his wife Frances, took in Edgar. His older brother, William, was taken by his grandfather and his sister, Rosaline, was taken by another family member that lived in Richmond. They loved him like their own child. This was how Edgar received his middle name Allan, threw his new family. In 1815, John Allan moved his family to England and while there Edgar was sent to private school. For five years he studied in England with his new family that he loved very much. After his five years in England the Allans moved back to America. It was said that Mrs. Allan loved Edgar very much, but the story was different with John. Although Edgar and Johns relationship may have seemed at times unloving John always took care of Edgar and in return he had Edgars respect (Wright). In 1826, Edgar went back to America; there he attended the University of Virginia. He was an outstanding student and excelled in vario...

Sociology is a Science

Sociology is a Science Free Online Research Papers Sociology is the study of social rules and processes that bind and separate people not only as individuals but as members of voluntary associations, professional bodies, groups, and institutions. One might argue that because the subject of matter of sociology is more difficult to study and interpret than the subjects pursued in other sciences, it does not mean the scientific method is not appropriate for the social sciences. The subject of matter of sociology undergoes continuous change. This fact alone portrays efforts at prediction difficult. For that of the Natural scientist, it should be noted that the problems encountered as biologists try to track the AIDS virus, as it too continually mutates. Sociology is a science just as much as biology and chemistry. Social Sciences, like natural and biological sciences, use a dynamic methodology. This simply means that a social scientist clearly states the problems he or she is interested in and clearly spells out how he or she arrives at their, his or her conclusions. Generally, social scientists ground the procedure in a body of existing literature. This is precisely how other sciences function. Like Natural Scientists, the role of a sociologist is to observe, measure and explain what can be observed and formulate theories when human behavior is perceived. Regardless of the fact that Natural Scientist experiment in labs, Sociologists too carry out experiments, while they are not in labs, sociologists interview, and question people and go about finding information in a direct way. The ideas behind sociology have a long history and can trace their origins to a mixture of common human knowledge, works, art, and philosophy. Sociology is coming from the age of enlightenment this was when people began to think and reason. It came out of the belief in the human ability to change i.e. humans can cultivate or culture their own actions. It also came out of the scientific revolution, this revolution challenged the belief in God, hence created the ideas that there were laws in nature. The Political and social revolutions led to ideas such as democracy, social equality and freedom of speech. A famous positivist Auguste Com Te believed that Sociology is a science. He thought it was the study of Human behavior based on principals and procedures and these procedures are similar to those of Natural Science. He also believed that humans were guided by the inevitable laws of ‘ Cause and Effect’ ( with every action there is a reaction ). Sociology has 6 major chara cteristics that can be an attribute to the belief that Sociology is a science. 1.) Sociology is empirical which means it can be observed and reasoned out. 2.) It is theoretical, which suggests Sociologists summarize their observation in abstract and logical observations or principles which can explain causal relationships. 3.) It is cumulative, which implies that Sociologists build on each other, this merely means because Sociology is ever changing, new theories are developed and so the expansion of older theories take place. 4.) It is objective because it puts aside all prejudices and bias’s. 5.) Sociologists detach themselves from individuals thus, it is Investigative, e.g. They don’t say whether an action is good or bad, They explain the good and explain the bad. 6.) Sociology is non-ethical, therefore, it puts aside prejudices and beliefs. Realists such as Roy Bhaskar (1979), Andrew Sayer (1984), Keat and Urry (1982) believe that scientists try to determine the underlying structures and process that cause observable events (e.g. evolution). Sociologists try to do exactly the same, looking for social structures (e.g. in Marxism the economic base and superstructure of social classes) and processes (e.g. capital accumulation). Based on the following information, it is my opinion that Sociology is a science since it can be observed, measured and reasoned out.

The Purpose of Judicial Review essays

The Purpose of Judicial Review essays What is Judicial Review? It is when the High court has to come in and review a decision that was made by the legislative or the Executive Branch of the Federal Government. It is also an option when the State courts make a ruling and it is challenged by the defendant, to seek if their ruling was made by the guidelines of the Constitution of the United States. To further analyze a Judicial Review, it is the Supreme Court of the United State, whom by the founding fathers of this country wrote the Constitution of the United States. At the time of the signing of the Constitution it did give the power to the Justices of the court to decide whether laws line up with the Constitution or they dont. It wasnt until the 1800s that this power was granted to the Courts to in other words become the watch dogs of this country in order to make sure that we the people have and enjoy the protections granted to us by the Constitution of the United States. Interesting enough, there are state and a federal courts. However, the Supreme court is the highest court in the land. In the Constitution, there are certain articles and one of the articles that give credence to the laws of the Supreme Court is Article VI, Clause 2. This Article is known as the Supremacy Clause. The Supremacy Clause of the Constitution paraphrase says that the Supreme Court and its laws are the supreme laws of the United States. It also subjects all of the state laws to line up with constitution and that no state laws shall be in violations of laws that dont line up with the Constitution. The States have an obligation to uphold what is known through the Constitution as a national law. National law is the Constitution this is what the Nations laws are based on. If the laws dont line up with the Constitution then they are brought to the Supreme Court of the United States where they will review the constitutionality of the law.The state court ...

Models of Organized Crime Executive Summary Essay

Models of Organized Crime Executive Summary - Essay Example Scholars proposed several models. Two such models propounded by Albanese (1989; 1994, as cited in Lampe, 2003) is the bureaucratic model (hierarchical) and patron-client model. The crime group Cosa Nosa was originally studied to belong to the bureaucratic model but also categorized by other scholars under patron-client model who challenged the earlier categorization (Williams, n.d.; Lampe, 2003). Cressey (1969, as cited in Lampe, 2003) typifies the hierarchical model as a â€Å"nationwide bureaucratic organizational entity† (para. 3). Joe Albini (1971, as cited in Lampe, 2003) and Francis and Liz Ianni (1972, as cited in Lampe, 2003) saw the patron-client model as a â€Å"web of asymmetric ties† interlinked with the regional and cultural networks (para. 3). The organized crime bureaucratic model has a â€Å"hierarchical or pyramidal structures† with branches nationwide, operates an illegal cartel, the bureaucracy governed by a central commission, and there is a clear-cut division of tasks and specialized functions among the branches (Williams, n.d., p. 62). Therefore, it is described as more corporate in structure with defined operative functions. OC under this model has specific skills and expertise, administer the organization through hierarchy and follows a procedure (Abadinsky, n.d.). The structure depends on the particular skills and capacity of mem bers and not on ethnicity (Abadinsky, n.d.). The organization even hires employees, secretaries, accountants and lawyers (Abadinsky, n.d.). Embarking on new illicit ventures is motivated by purely financial concerns and not by power or personal consideration (Abadinsky, n.d.). The patron-client model, used as a political machine, can be traced on the in-flow of migrants from other countries (Abadinsky, n.d.). The migrants that grew dramatically from early 1900s to mid-1900 were discriminated upon, the object of hostility and worked on dangerous conditions (Abadinsky, n.d.). They were harnessed by a

This is a repeat from yesterday, and I still need two solid paragraphs Essay

This is a repeat from yesterday, and I still need two solid paragraphs answering the below listed question. I have included more - Essay Example Also, the U.S. was just beginning to enter the Industrial Age, changing American society dramatically. Production was soaring because businesses boomed. People moved out of the cities if they could, because there was a wide income disparity between the working class and the urban middle class. In addition, Prohibition was legally enforced while the 18th Amendment was valid, forcing people to stop making moonshine liquor and patronize bars—however, this legal technicality did not in effect erase peoples’ drinking activity completely, but rather just suppressed it. (People still made liquor illegally, buying it and selling it.) The results of these changes were a New Urban Culture, New Moral Standards, and New Consumer Ethics. A New Urban Culture flourished. As industrial work no longer could meet the demands for low-skilled workers in the polis, industrial operations began to move to the rural areas—where there were more low-skilled workers who: most likely had le ss education; were willing to work for less money; and were not averse to doing skill that required more physical labor and less intellectual faculties. Also, as people became more middle class, the demand for physical labor decreased. Industries moved to rural areas to stay afloat. New Moral Standards emerged as well. ... The advent of the 9-to-5 office job eclipsed most physical labor that had previously been the backbone of the American work force. More jobs began to require degrees in higher education, and more people began to—as a result—seek more education from institutions at higher learning. Several excellent schools had begun to gain exeter reputations in the early 20th century, such as Harvard, Yale, and Princeton. Education became much more of a focus as several industries moved from the urban to the rural areas. Once the ‘20s were over, people started moving in an exodus out of the city once they had achieved some level of social mobility. Conflict ensued with the Scopes Trial (also famously known as the â€Å"Scopes Monkey Trial†), a lawsuit of the State of Tennessee versus John Scopes, a biology teacher who taught evolution—when it was illegal to teach evolution due to the way Tennessee state law was structured. Although Scopes was deemed guilty, he got o ff on a technicality and was never put in jail. Around this time, the eight-hour, five-day work week with two weeks paid vacation became the standard and not the exception in terms of what had traditionally been the standard—which included longer hours, no free time on the weekend, and no paid vacation. Industry—although initially urban—eventually moved to rural areas, due to the fact that industrial jobs needed low-skill laborers while the public was becoming increasingly educated and more middle class. 2.) Describe the impact of the New Deal on American government and society. In doing ?so, be sure to discuss the primary goal and basic overall characteristic of several specific New Deal programs. (450 words) The New Deal was the first comprehensive socialist program put

How were the pyramids at Giza Constructed Essay Example | Topics and Well Written Essays - 500 words

How were the pyramids at Giza Constructed - Essay Example The great pyramids consist of huge stone blocks, carefully measured out and carved, and then slotted in to fit a perfect geometric shape on a truly colossal scale. Scientists today are still trying to figure out how a nation without modern lifting equipment and mechanized transportation could possibly have had the technical skill and physical power to construct these tall edifices in the sandy ground. The fact that the Egyptians possessed such a capability is undeniable, since the pyramids are still standing there as evidence. How these people managed this great feat is, however, a deep mystery. It has long been recognized that the ancient Egyptians used ramps and wooden sleds to transport huge blocks of stone from the quarries to the building site, and that there is no evidence that they knew about the wheel, the pulley or the derrick (Dunham, 1956, p. 161). It seems that they just built ramps and used many thousands of workers, and this simple explanation is widely accepted. Another, much more radical theory has been advanced by Danish scholar Erich von Dà ¤niken who argues that it would have taken human beings some 600 years to build the great pyramid of Cheops, the largest of the pyramids at Giza, shifting more two and a half million blocks of stone (Von Dà ¤niken, 1970, p.96) and using tens of thousands of workers at any one time. He theorized that there was insufficient food and shelter for such a number of workmen in the largely desert land around the area, and that therefore the ancient Egyptians must have had help from some supreme god-like beings from outer spac e. Assembling arguments gathered from other massive structures across the planet, and from legends about Egyptian gods such as Ra, who â€Å"travelled through the heavens on a bark† (Von Dà ¤niken, 1970, p. 94), the theory of ancient aliens helping to build the pyramids emerged. The two theories outlined above argue on very different principles. Von Dà ¤niken’s argument is based on vivid

National Revival in Wales between 1880 and 1914 Essay

National Revival in Wales between 1880 and 1914 - Essay Example 205). Perhaps Keir Hardie's greatest contribution, however, was in the genesis of the Labour Party in Britain. Hardie had been an ardent member of the Liberal Party, but he felt that the policies put in place by William Gladstone fell far short of representing the interests of the working classes. While the Liberal Party would make big promises in exchange for the votes of workers, it would never carry out meaningful policy changes that would help the workers' condition, and so in April 1888, Hardie ran as an independent labour candidate in West Lanark. While he came in last, he was encouraged about the future. In August of that year, the Scottish Labour Party was formed. Hardie won a seat in Parliament in 1892. Interestingly, for his first session, he did not wear the same outfit that other working-class MP's wore; instead, he wore only a plain tweed suit, red tie, and deerstalker hat. He was in favor of such progressive policies as free education, pensions, the abolition of the House of Lords, suffrage for women, and a progressive income tax (Wrigley 2002, p. 203). In 1893, Hardie was one of the founding members of the Independent Labour Party. However, two years later, Hardie found himself out of Parliament. An explosion at a Pontypridd colliery had killed 251 miners, and Hardie asked that a message of condolence be added to a Parliamentary address giving congratulations for the birth of a royal heir (the future King Edward VIII). After this was refused, Hardie made a speech attacking the monarchy and lost his seat in 1895 (Wrigley 2002, p. 205). However, Hardie was not out of politics for long. He spent the next five years making speeches and, in 1900, put together a meeting of trade unions and socialist groups, which agreed to form the Labour Representation Committee, which was the precursor of the Labour Party. In that same year, Hardie was elected as the junior MP for Merthyr Tydfil and Aberdare in the South Wales Valleys, and he would represent this region until his death in 1915 (Wrigley 2002, p. 207). The election in which Hardie returned to Parliament became notorious in history for another reason as well. The British military was involved in the Second Boer War, and this war became the primary issue in the 1900 British general election. The Conservative government of Lord Salisbury was reelected, with an enlarged majority over the Liberal Party. There were a couple of reasons for this enlarged majority: not only did the British public want to rally behind its government and support the war effort, but the emergence of the Labour Party created the possibility of vote-splitting among the opposition, as some might vote Liberal and others Labour, which would assist the Conservative cause. Because of this, and because of some funding shortages encountered by the Liberal Party, over 100 races did not have a Liberal Party opposition candidate. The election became known as the "khaki election," because of the new khaki uniforms that the British Army was wearing at war. This became a po pular term in British politics for an election that is decisively influenced by wartime or postwar emotion. Other elections in British

Drug trafficking analysis in UAE Thesis Proposal

Drug trafficking analysis in UAE - Thesis Proposal Example Financial cost on society and individuals is one of the significant problems of drug abuse. For example, in 2002, drug related cost was estimated at $180.9 billion consisting of various costs of health care and loss of labor according to the national drug control policy office. In 2004, it took US$3 million to set up a sub-office on drugs and crime in the UAE. UAE has been the target by exceptionally determined criminals who have access to adequate capital and labor to produce and smuggle voluminous amount of prohibited substances. Drugs originate from south Asia and pass through the emirates to Europe and North America, the heavy consumers (Shindagah, 1998). States in the gulf remain key destination markets for opium and psychotropic substances. Other countries such as Syria, Jordan, Lebanon and Iran continue to be the hotspots for drug manufacturing as indicated by international narcotic control board report (Reinil, 2009). Narcotics are the most trafficked drugs in UAE and are estimated to be worth US$500billion annually, according to Sherman and Tree (2010). This amount is estimated to be double that of the automobile industry (Scott, 2005) Ports are the most notorious places and foremost hotspots and avenues of drug trafficking due to the voluminous imports received daily, with Small scale dealers mostly caught at airports. The commonly used tactic of drug trafficking continues to be through the internal human body carriage. However, smugglers are always changing their tactics and the current trend as indicated by Reinil (2009) is the use of Christmas cards. One of the biggest tasks is to prevent the flow of heroin from Afghanistan, which produces 90 per cent of the worlds supply. According to Jamieson and Research Institute for the Study of Conflict and Terrorism (1990), most of the drugs grown in Afghanistan pass through the emirates before being shipped to their final destinations. There is a rising use of

High Speed 2 (HS2) (London Birmingham Phase) Assignment

High Speed 2 (HS2) (London Birmingham Phase) - Assignment Example High-speed rail is a type of transport mode, which uses electric rails to offer transport at a faster speed than the current carriage railway. It may have a speed ranging from 200km/h to 350km/h. The European Union considers high-speed railway to be equivalent to 200-300km/h, while in India and Australia they consider it 250-500km/h. In Japan, they have the 300km/h rails in operation. This type of train operates specifically on areas where there are minimum closings. Mostly high-speed trains are meant for human transport (Zhou and Shen, 2011). High-speed railway is an invention of the Japanese as Japan was the first country to design and use to help this form of transport to reduce congestion in their cities. They develop an electric rail, which was travelling at a speed of 145km/h. At that time, the Japanese engineers wanted to develop a form of train that was faster and reliable mode of transport to ease the congestion in cities of Tokyo and Osaka. In 1963, they were able to produce an electrical rail that operates at a speed of 256km/h, which was used including the time of Olympics in 1964. This train eased transport in Japan. In 1965, the Japanese and the French introduced a similar rail but United Kingdom became the first European country to have a regular service of rail, which travels at 200km/h in 1976.Since, then there has been a construction in various parts of Europe. There is also a construction of high-speed rail services between countries such as, Belgium, Britain, and France. There is a high-speed rail betw een London and Paris as well as Brussels –London (Zhou and Shen, 2011). Currently Japan and France are operating high-speed rails. France has a conventional rail, which operates at a speed of 575km/h. while France operates unconventional rail, which operates at a speed of 581km/h. China, which has the world largest population, has a rail that operates at a speed of 500km/h, and it became the

Climate Change Essay Once, I visited a hospital for my health checkup,there I saw a man with shattered skin,rashes all over the body;clearcut it was the case of allergy.Doctors are rushing and making report on it.After a week I again visited that hospital for my scheduled checkup,then I came to know a shocking news-that allergy case was the case of Ganga bath!! Alas! Holy river Ganga, ancient river Ganga ,that Ganga which takes away all the sins from mankind, today causing allergy,irritation,skin rashes!!! that man has to pay price for his religious belief†¦ Also scientists got some samples from Ganga from specific places having disease causing microbes. This small case itself indicate the change we have made in our nature. Change is the law of nature,change is inevitable and change is evergoing process,but Climate Change is one of the most complex,multifaceted and serious threat that the World face. Whether you are adding your bit to the heap of garbage piling up in your locality or not become meaningless when the garbage begins to rot-the stench will reach your nose too,Climate Change induced by global warming works much the same way. World famous scientists all over the country had evaluated climate change and came to conclusion that Greenhouse Gases ,CFC, Carbondieoxide and many other toxic gases are the cause of environment degradation.Though it is true scientifically,the root lies elsewhere;that is in the greed of human being.Our greed led to adavancement of technology and led us farther from peace and prosperity of all. Increasing consumption of electricity due to intiation of several new industries,disposal of garbage without treatment to maximize profit,use of environment hazardious substances like polythene in our daily life are concrete examples of human greed. People have been influencing the Biosphere for at least 8000 years,since the invention of Agriculture,but Climate Change has proposed a threat over our Agriculture.The most affected area of Climate Change will be Agriculture and its biodiversity. The first and foremost impact of climate change is in biodiversity specially Islands biodiversity.nearly one –fourth of the worlds countries are Island and they are treasure trove of biodiversity.Also they provide food,fresh water ,wood,fibre,medicine,fuel and other raw materials. But increasing sea level has given a alarm threat to them,The New Moore Island of India in Sunderbans has been consumed recently by rising sea,many other Pacific atoll nation Island of Kiribati,Islands of Vanuatu also submerged in early history.we are loosing huge . biodiversity;these are initial cases†¦ Rather IPCC has warned that a rise in sea levels of between 18 and 59cm by 2100 would be enough to submerge many other big islands, including Maldives and make them unhabitable,also of the 724 recorded animal extinctions in 400 years about half were Island species .also climate change will bring degradation of coastal environment and natural resources on which poor rural people depend.Higher rates of erosion and coastal land loss may vanish our islands In context of Agriculture,sea level rise will also cause increased salinity due to encroachment of the sea and saltwater intrusion into freshwater lenses,contributing to an increasing shortage of water supply and loss of agriculture land.The most vulnerable section will be the poor and marginal farmers with small landholdings because ‘extreme weather events’will specially occur in tropics,fundamental changes in rainfall pattern together with rising temperature will shorten growing season and reduce crop productivity . Acco.to World Bank 75% of 1.2 billion people are trapped in extreme poverty,so they will fail to adopt new rotation practices and thus most vulnerable to climate change. World wide farming is a significant source of greenhouse gas emissions accouting for 20% of total emissions.Atmospheric concentration of methane has more than doubled during the past 200 years.Natural wetlands,fossil fuels related to natural gas,coal mines coal industry,electric fermentation,rice fields,biomass burning,landfills accont for 75% of methane production in our environment. thus major source of greenhouse gases is agriculture itself. Rice fields are the most significant contributors of atmospheric methane accounting for 11-13% of the world’s total methane production. Also, rice production will need to expand by around 70% over the next 25 years to meet the demands of fast growing human population whose food demand is expected to double in developing world in next 40 years. Thus if we increase our crop area specially staple crop area in near future then the problem of global warming is likely to increase. Already in today’s era 800 million people are unnourished, in India only 30 million people suffer hunger,46% children are underweight and 17000 people are dying per day due to hunger on an average. Thus in near future we are going to face a great threat not only of climate change but also of food security†¦. However, Not all effects of climate change on agriculture are expected to be negative, most of the major food crops are C-3 plants including staple food like rice ,wheat, oat, barley will show increase in yield ranging from 25% to 64% due to increased CO2 level, also most of the noxious weed are C4 plants and their growth will be checked. But this is only one side of the coin ,increased temperature due to increase in CO2 level may rise the pest attack up to 25% and fungal disease attack up to 20% and also disturb our monsoon pattern.In an overview it can be said that it will create more and new problem rather than benefits because the worst sufferers would be farmers of Rainfed agriculture which cover 60% of all cultivable lands. Today humanbeings have become dependent on technologies which are dependent on non -renewable resources and produce illeffects in long run.nowdays we say that glaciers are shrinking;may be shrinking but more that the heart of the people and their philosophy is shrinking too.while the drastic effects of global warming has been discussed in many scientific circles,had their run on T.V. and even had well meaning Hollywood films but the need of the hour is to change ourselves,to reduce our luxurious wants. The need of the hour is to develop a) True sustainability,there should be synergies between climate mitigation strategies and development policies in areas of energy efficiency,fuel substitution,renewable ,afforestration,and land and waste management. b) The planning should not be for temporary economic gains and support,but for sustainability in future as well.There should be partnerships with communities,individuals,and private sector to frame effective measures to reduce the impact the effect of climate change. Today we all peoples of the world need to change our habbits ,not only in Agricultural practices but also in our daily life practicices†¦ Switching of fans and light before leaving room ,efficient use of water at home , proper garbage disposal at micro level, though seems to be a very minute step but the huge building of true sustainability will only form above these basic steps because this will be the 1st step against our greed, so step ahead and realize your own responsibility ,because it is not the time to curse the darkness but to light a small lamp.

Recruitment Strategy at HiTec International

Recruitment Strategy at HiTec International Introduction: Problems: Advice: Step 1Provide a Positive Working Environment Step 2Recognize, Reward and Reinforce the Right Behavior Step 3Involve And Engage Step 4Develop Skills and Potential Step 5Evaluate and Measure   Introduction: HiTec International is the company which is emerging organization. It has annual turnover of more than $19billion in current and employs more than 30,000 people across the world. The headquarter of HiTec which is located in West Dublin employs 2500 people in which 90% are permanent employees and remaining are on contract basis. HiTec have some expertise in procurement of hardware and bespoke programming solutions for corporate customers to aid them in boosting the utilization of the web. HiTec likewise give a complete after sales services which go beyond maintenance of software. The organization is perceived as worldwide business sector pioneers in a few of its central line of business. Because of the focused market that HiTec works in development and persistently advancing engineering improvements through innovative work division is vital to the organizations future achievement. HiTec offers workers brilliant terms and states of livelihood with top-pay rates, liberal extra plans, rebates, benefits, and wellbeing and life coverage. The earth in which they work is extremely alluring with superb offices, for example, staff cafeterias, wellness offices and valet administrations. Staff retention is great; turnover levels are at present at 5% of which half are represented by dismissals and non-renewal of fixed term contracts. Problems: HiTec are encountering some troublesomely with discovering sufficient number of workers with the obliged aptitudes to reach its development needs. Because of the quick moving nature of the industry which makes it difficult to usefully employ graduates with limited experience and train them. With the time, they learned a lot of skills and then moved on to another organization to learn more skills. HiTec likes the people which are employed in companies to who with HiTec has a customer relationship and in partner companies but HiTec has a long standing policy to not recruit from these sources. However, HiTec is recruiting people through advertisement in national newspapers and with the use of headhunters but this also not succeeded because through national newspapers the people who are properly qualified are few and head hunters are also not succeeded due to target labor market is so small. Advice: HiTec should explore the fundamental reasons of people leaving the jobs. HiTec should distinguish new methods and strategies, for example, making a developing leaders program, giving preparing to directors, and enhancing their representative distinguished program. As a result, they will draw in better ability and all the more significantly will have the capacity to hold best individuals. And the HR Department will be more satisfied in light of the fact that they wont spend all their time conducting training. HiTech can improve their ability to attract, retain and improve productivity by applying the following five-step PRIDE process: P Provide a Positive Working Environment R Recognize, Reward and Reinforce the Right Behavior I Involve and Engage D Develop Skills and Potential E Evaluate and Measure Step 1Provide a Positive Working Environment HiTec should provide a positive working environment to its employees to retain them for a longer period. Employees quits the jobs for many reasons but one reason for quitting them is the relationship with their first line-supervisor because the fact is that managers and supervisors are totally unaware with their actions that can affect employees. Manager training is a critical aspect for an effective retention strategy. Suitably trained managers play a key part in an effectual recruitment and retention policy. Managers need the skills, tools, and knowledge to help them understand their employees retention needs and be able to implement a retention plan designed to increase employee engagement in the organization. Step 2Recognize, Reward and Reinforce the Right Behavior Cash and profits may draw in individuals to the front entryway; however something else needs to keep them from going out the back. Individuals have a fundamental human need to feel acknowledged and pleased with their work. Recognition and motivation projects help address that need. A fruitful prize and recognition program does not need to be confused or lavish to be compelling. Hitec ought to offer prize to its workers. In a few organizations CEO frequently give their extravagant auto keys to their workers for a week or for an outing. This inventive approach to remunerate workers has a greater effect than money. In the event that you gave someone a $200 reward, it wouldnt mean all that much. When somebody gets to drive an auto for a week, they always remember it. For Example, At First American, administrators exhibit a Greased Monkey Award to the machine specialist who is best in determining issues with machine programs. The recompense is a plastic toy monkey in a container of Vaseline alongside a $50 supper testament. A supplies wholesaler remunerates each workers work celebration with a cake and a check for $200 for every year utilized. Twice a year workers kids get a $50 reserve funds security when they accumulate their everything As report card. Whats more, they compensate workers with a Security Bonus Program. They screen each representatives driving record twice a year, and any individual who has a reference is expelled from attention. Those representatives staying toward the end of the year separate $2,000. On Fridays, all representatives pivot employments for one hour. This fabricates a stronger group, solidarity, and enhances correspondence inside the organization. Step 3Involve And Engage The directors of Hitec ought to be included and captivate with the workers. Individuals are more dedicated and captivated when they can help their thoughts and proposals. This provides for them a feeling of proprietorship. Hitec ought to have a capacity to make and produce new and creative items. Keeping in mind the end goal to encourage the trade of thoughts inside offices, they ought to support a yearly Idea Exposition. Amid the article, researchers and designers showcase ventures and thoughts they are chipping away at. This procedure makes a solid atmosphere of development and captivates each one of the individuals who take an interest. Organization should have a unique way of making its employees feel valued and involved. One wall within the company contains the photographs of all employees who have worked there more than five years. Their equality program goes beyond the typical slogans, posters, and HR policies. There should no reserved parking spaces or other perks just for executives everyone is an equal. This is one reason why companies can be best employer company. Step 4Develop Skills and Potential For the vast majority, vocation opportunities are generally as vital as the cash they make. In a study by Linkage, Inc. more than 40 percent of the respondents said they would consider leaving their present boss for an alternate occupation with the same profits if that employment gave better vocation improvement and more prominent difficulties. So Hitec ought to create abilities and possibilities for their staff to hold them/ Hitec ought to find that why they were losing gifted individuals to different organizations and they ought to lead passageway reviews to discover what number of representatives who left to take new occupations and vocations outside the organization and can accompany the same employments and professions inside Hitec. As an issue they ought to make with an intranet-based improvement and profession guiding project for all representatives. This will bring about over of workers who left the organization and representatives will exploited the project and perspective inside employment opportunities. Not just does the system give new openings for work, however Career Connections offers an assemblage of profession improvement instruments, for example, assessments toward oneself, apparatuses to create continues, and articles on different occupation looking for techniques inside the organization. Gifted individuals wont stay in a vocation in the event that they see no future in their position. To wipe out the inclination of being in a deadlock work, each position ought to have an individual advancement plan. Step 5Evaluate and Measure Nonstop assessment and endless change is the last venture of the PRIDE framework. The main role of assessment is to measure advance and figure out what fulfills and de-fulfills your workforce. The assessment procedure incorporates the estimation of demeanor, confidence, turnover, and the engagement level of the workforce. Here is an agenda of things that ought to be incorporated in Hitecs assessment and estimation process. Carry out an employee satisfaction survey at least once a year. Improve your contracting methodology to make a finer match between the singulars abilities and employment prerequisites. Examine those divisions that have the most elevated turnover rates. Hold chiefs in charge of maintenance in their area Initiate interviews and surveys concerning the real reasons people come to and leave your organization. Provide flexible work arrangements for working parents and older workers. Start measuring the cost of turnover. Focus on the key jobs that have the greatest impact on profitability and productivity. Design an effective employee orientation program.

Ballistic Missile Defense Essay -- American Government, Nuclear Arsena

INTRODUCTION Today we live in a time where developing countries and terrorist organizations are vying for world power. A common way this is attempted is through the attainment of nuclear arms and delivery systems for them namely Intercontinental Ballistic Missile (ICBM). Many of these countries are hostel to the United States and her allies. Also the existence counties with large nuclear arsenals such as Russia, increase the chance of an accidental launch. In order to counter threats form rouge nations and accidental ballistic missile launches, the United States should pursue development of a missile defense system. COLD WAR AND THE ABM TREATY The first ICBM, The R-7, was developed by the Soviet Union in 1953 (Korolev). After this event, both the Soviet Union and the United States started to develop and deploy increasingly powerful and accurate ICBMs. This build up of powerful weapons caused an escalation in tension between the U.S. and the USSR, both expecting an attack at anytime. The potential destructive force the weapons had and the high tension environment led to the theory of MAD or mutually assured destruction to come into existence. This theory works on the principle â€Å"that deterrence against a nuclear attack was to be maintained through the ability of each side to inflict an unacceptable degree of damage† (Lettow 22). MAD is the thing that kept nuclear Armageddon form occurring during the Cold War as both sides new that if they launched an all out attack, the other side would as well, destroying both. MAD relies on an equal balance of force, so that no one country feels like they could come out ahead in a nuclear war. Many top strategic experts were concerned that ABM systems could destabilize this delicate ... ...3). Although this is not a small amount it is a large improvement over the 1.2 trillion dollars required for a SDI scale project. The benefits conferred by this kind of plan: protection against small scale ICBM attacks and TBM attacks is worth the price. â€Å"The ultimate goal of missile defense is to convince countries that ballistic missiles are not militarily useful or a worthy investment and placed doubt in the minds of potential aggressors that a ballistic missile attack against the United States or its allies can succeed† (Missile Defense Agency). This form of missile defense would act as a deterrent to those countries to whom MAD does not apply. Countries hostile to the U.S. would be discouraged from attempting to use ballistic missiles against the U.S. in any first strike or strategic ways as it would provide no tactical advantage(Kaufman 116).

Benjamin Franklin :: essays research papers

Benjamin Franklin took pride in almost every aspect of his life. There are many instances in which one could call him a vain man. Franklin writes to Ezra Stiles and speaks of his portrait being hung at Yale. Franklin complains that the portraits he has of himself do his stunning features no justice, and are certainly not worthy to be hung at Yale. He suggests that a new portrait be painted. Franklin clearly has issues as to how he will be remembered, and also how obsessed the man is with his looks. He writes, â€Å"I do not think any one of the portraits you mention, as in my possession, worthy of the place and company you propose to place it in. You have an excellent artist lately arrived. If he will undertake to make one for you, I shall cheerfully pay the expense.† This vanity of Franklin’s is presented in his â€Å"Apology for Printers† as well. He argues that printers print silly things not worth reading not because they want to, but because people are uned ucated and like to read mindless garbage. Franklin, in his mind, has set himself on a higher pedestal than the everyday man. He has a better education therefore he is a better person. He writes, â€Å"They sometimes print vicious or silly things not worth reading, it may not be because they approve such things themselves, but because the people are so viciously and corruptly educated that good things are not encouraged.† Franklin also presents a vain attitude toward religion. He goes as far in his letter to Ezra Stiles as to indicate Jesus Christ as merely a good philosopher, and he himself does not care to take the time that religion requires. He believes that he will find the truth for himself. The man put himself above others’ intelligence and beliefs and disregarded them as distractions and wastes of time for him. He says, â€Å"I have, with most of the present Dissenters in England, some doubts as to his divinity; tho’ it is a question I do not dogmatize u pon, having never studied it, and think it needless to busy myself with it now, when I expect soon an opportunity of knowing the truth with less trouble.† Franklin clearly displays his vanity throughout his writings. Benjamin Franklin often used his own sarcastic sense of humor to win over his audience. An example is Franklin’s â€Å"Apology for Printers,† in which he defends himself after accepting and printing a routine announcement of the sailing of a ship with a captain thought to be anticlerical.

Case study on electronic company Essay

ABSTRACT †¢ There was a electronic gadgets manufacturing organization wanted to launch a device which measure blood pressure at home with fixed price at Rs. 3000 per piece. This firm had no proper channel of distribution. This device help a person to measure his blood pressure at any place whether in home or office without having to visit the doctor. By availability of this product it save the time. The company made cold list and hot list of the people which were below and above 45yrs of age have the income more than Rs. 15000. Company released the coupons in two leading business paper in Bombay and asked to the individual to fill the printed coupons and send it to within 10 days to get a free booklet on management of blood pressure. The coupons consists of name, age, income, profession, residential area and details of any health related problems were to be filled in. Most of the people who responded were suffering from blood pressure , obesity and heart related problems. A cold list of about 5000 individuals was generated but only 3500 respond to that. Another method adopted by the company is to get a list of credit card holder from the different banks. Company sorted out the names of persons who were above the age of 40 yrs and which occupy senior executive position in private or public organization. Company offered those people brochure and a personal letter for free demonstration of products. Company have logistics problems.

Routing Protocol

1. INTRODUCTION 1. 1 What  is Computer Network? The group  of  computers and devices linked by communication channels allowing users to share information, data, software and hardware with further users is meant to be computer network. Network protocols bound hardware as well as software components of network. Two or more  computers are said  to be  in  a network if and only if they are connected  mutually  and  are  able  to commune. Computers are connected to a network by the use of all  the ports i. e. , parallel ports, modem ports, Ethernet ports, serial ports, USB ports  , fire wire ports and many more in one or more way. But Ethernet port is the most broadly used ports  for networking. Hosts, end stations or workstations are referred while talking  about networks. Anything  attached  to  the network  including hubs, bridges, switches, routers,  access points, firewalls, workstations, servers, mainframes, printers, scanners, copiers, fax machines  and more are included under Host or end stations . Computers are connected in a network for sharing of software and hardware resources, information and data as well as smooth the progress of communication. 1. 2 TCP/IP Layered  architecture Fig: TCP/IP Layered  architecture The following  are  the layers  of  the TCP/IP  architecture: Application Layer: In the  application layer Simple Mail Transfer Protocol (SMTP) and File Transfer Protocol (FTP) uses protocol  for network communication. Application layer protocols  are most  frequently  linked with client-server  applications. Transport Layer: End-to-end message transfer capability, flow control, error control and fragmentation etc are provided  by the transport layer. The transport layer ensures source to destination delivery of packets safely and reliably. The service through which applications are connected  together via  the use  of ports is provided by transport layer. Network Layer: Packets are logically transmitted over  the entire network in the OSI’s Network layer. Hosts addressing by assigning  them  an IP  address  and packet routing among multiple networks are handled in this layer. This layer is concerned with routing data; end to end message delivery etc. Interface Layer: The data exchange between  the host  and  the network are monitored by the  interface layer. The protocols for  physical transmission  of data is defined by Interface Layer . 1. 3  Autonomous System IP networks  and routers collection under  the control  of one entity representing a common routing policy is called an  Autonomous System. Each  AS  have a unique  AS number  for use  in routing. Each network is uniquely identified on  the  internet by ASN. IANA (Internet  assigned Numbers  authority) assign AS numbers  and supply  to Regional  internet Registries (RIRs)  in blocks. Autonomous System can be divided  into three categories: Multihomed  Autonomous System:   Connections  to more than one  AS is maintained by a Multihomed  AS. Stub  autonomous System:   Connection  to only one other  AS is Stub  autonomous System. Transit  autonomous System:  Connections through itself  to separate networks are provided by Transit  autonomous System. 1. 4 Routing The method  of selecting paths  in  a network via which  to send data is meant to be routing. The process  of finding  a pathway from  a sender  to  a desired destination is also said to be routing. The telephone network,  the  internet  and transport networks, etc perform routing. Network Layer  of either TCP/IP layered model or  the OSI (Open System  interconnect) Reference model mainly carry out routing. The logically  addressed packets are passed from  their source  to destination via  intermediary nodes i. e. orwarding is directed by routing. Routing tasks are performed by routers. Routing and packet forwarding is performed by ordinary  computers available with multiple network cards in a limited manner. Forwarding is directed by the routing process on  the basis  of routing tables where routing record to different network destinations are maintained. In order to have efficient routing, construction of routing table held  in  the routers' memory is most necessary thing. Only one network path are frequently used by routing  algorithms   at  a time, but  the use  of multiple  alternative paths is made possible by multi-path routing techniques. Following are the types  of routing delivery semantics: Unicast: A message is delivered to  a single specified node by router. Fig: Unicasting Broadcast:   A message is delivered  to  all nodes  in  the network by router. Fig: Broadcasting Multicast:   A message is delivered  to assembly  of nodes that have expressed  interest  in getting  the message by router. Fig: Multicasting Anycast: A message is delivered  to  any one out  of  a set  of nodes, typically  the one next  to  the source. Fig:  anycasting 2. TYPES  OF ROUTING Following are the types  of Routing mechanisms. They  are: Static Routing Dynamic Routing 2. Static Routing: The process  by which routes can be manually entered into the routing table with the help of a configuration file which loads automatically as soon as router starts is called static routing. Network  administrator, who configures the routes, can enter these routes as an option. Thus ‘static' rou tes mean the routes that cannot be changed (except  a person changes  them)   after their configuration. The simplest  type  of routing is static routing. In case of change of routing information often or configuration on a huge number of routing devices (router) it doesn’t work fine as it is a manual process. The outages or down connections are not handled properly by static routing because  manually configured route must be reconfigured physically in order  to fix or renovate  any lost connectivity. 2. 2 Dynamic Routing: Network destinations are discovered dynamically  by means of software  applications called Dynamic routing protocols. A routing table is created and managed by router  in Dynamic Routing. Firstly, a router will ‘learn' routes  to  the directly connected entire networks. It will  then learn routes from other routers using the same routing protocol. One or more best routes are selected from the list of routes for each and every network destination by router. ‘Best route'  information are distributed  to other routers running  the same routing protocol by Dynamic protocols, distributing  the  information on what networks it subsist  and can be reached. This provide dynamic routing protocols  the  capability  to  get used to logical network  topology changes, equipment failures or network outages ‘on  the fly'. 2. 3 Types  of Dynamic Routing Distance-Vector Routing Paths are calculated using Bellman Ford Algorithm by  a distance-vector routing protocol. RIPv1  and 2  and IGRP (Interior Gateway Routing Protocol) are examples  of distance-vector routing protocols. Earlier, distance vector protocols such as RIPv1 show classful behavior but newer distance vector protocols such  as RIPv2  and Enhanced  interior Gateway Routing Protocol (EIGRP) show signs of classless behavior. Distance-vector routing protocols †¢ Easy  and competent  in small networks †¢ Deprived convergence properties †¢ Facilitate in  the growth  of more complex but more scalable link-state routing protocols  for use  in large networks. Periodic copies  of  a routing table are passed from router  to router by distance vector routing  algorithms. †¢ Logical broadcast is the most commonly used  addressing scheme. Periodic updates are sent by routers running  a distance vector routing protocol even if  there  are no changes  in  the network. †¢ Complete routing table is included under  the periodic rou ting update in a pure distance vector environment. †¢ All known routes can be verified and changes can be made  by getting  a neighbor’s complete routing table based on simplified  information also called as â€Å"routing by rumor†. Fig: Distance Vector Routing Periodic routing updates are received from router A to router B in  the figure. Distance vector metric (such  as hop count) are added by Router B to each route learned from router A,  rising  the distance vector. Its own routing tables  are passed to its neighbor, router C. This process occurs  between directly connected neighbor routers in  all directions. The chief purpose  is  to decide  the top route  to  contain  in  the table when the routing table is updated by  a routing protocol  algorithm. Different routing metric is used to determine  the best route by each distance vector routing protocol. Metric value  is generated for each path through network by the  algorithm. Usually, the path is better if metric is smaller. Single characteristic  of  a path helps in calculation of metrics and combination of several path characteristics helps in calculation of more complex metrics. The most commonly used  metrics used by distance vector routing protocols are: Hop Count: Packet’s number  of passages throughout  the output port  of one router Bandwidth: Link’s data capacity Delay: Time necessary  to shift  a packet from starting place  to destination. Load: work load on  router or link. Reliability: each network link  bit error rate Maximum Transmission Unit (MTU):  the utmost message extent  in octets satisfactory  to  all links on  the path. Link-State Routing Packet-switched networks use link-state routing protocol  for computer communications. OSPF  and  IS-IS are its examples. A  topological database is built by the help of link-state routing that describes extra  precise  inter-network routes. Large networks use link state routing protocols and now used by most of the organization and ISP. Router performs the link-state protocol in  the network. A map  of  the connectivity  of  the network is constructed by every node in the form of graph showing node connection to other node is the basic concept  of link-state routing. The best next hop is calculated by each node  independently for every possible destination  in  the network. The routing table for the node is formed by  the collection  of best next hops. Fig: Link-State Routing To find out  the shortest path from itself  to every other node  in  the network an  algorithm is run by each node  independently over  the map. OSPF, EIGRP and Novell's NLSP (NetWare Link State Protocol) are the examples of link state routing protocol. IPX is only supported by Novell's NLSP. A partial map  of  the network is maintained by each router in this type  of routing protocol. Link state  advertisement (LSA)  is flooded throughout  the network when  a network link changes state (up  to down, or vice versa). The changes are noted and routes are re-computed by all  the routers  accordingly. Greater flexibility  and sophistication are provided by Link State Routing protocols than  the Distance Vector routing protocols. Overall broadcast traffic is reduced  and better decisions are made  about routing by taking characteristics such  as bandwidth, delay, reliability,  and load  into consideration,  instead  of taking  their decisions only on hop count. 3. ROUTING  ALGORITHMS 3. 1 Bellman-Ford  Algorithm: †¢ Also called as Label Correcting  algorithm †¢ Used for negative edge weight †¢ Same as Dijkstra's  algorithm †¢ In order to maintain distance tables, this algorithm is used by router †¢ Exchanging  information with  the neighboring nodes help to update information in the distance table †¢ All nodes  in the network is represented by the number  of data  in  the table The directly  attached neighbors are represented by the columns  of table and all destinations  in  the network are represented by the row. †¢ The number  of hops, latency,  the number  of outgoing packets, etc. are measurements in this algorithm. 3. 2 Dijkstra’s  Algorithm: †¢ Edsger Dijkstra  conceived Dijkstra's  algorithm †¢ Mostly used for routing †¢ Is a graph search algorithm †¢ The single-source shortest path problem  for  a graph is solved by this algorithm with non negative edge path costs †¢ The shortest path tree is produced as a output †¢ Helps in finding shortest route from one router to other A shortest-path spanning tree having route to all possible destination  is built by this algorithm for router †¢ The router using  the  algorithm  is  the source  of its shortest-path spanning tree 4. ROUTING PROTOCOLS Routing protocol describe the way of communication between routers which helps in the selection of routes between any two nodes on a network. Usually, knowledge of immediate neighbors is known by each router. This  information is shared by  a routing protocol to have routers the knowledge  of  the network  topology. Most commonly used Rout ing protocols are as follows: 4. RIP (Routing  information Protocol) †¢ dynamic  inter-network routing protocol †¢ used in private network †¢ routes are automatically discovered †¢ routing tables are built †¢ a Distance-Vector routing protocol †¢ uses Bellman-Ford  algorithm †¢ 15 hops are  allowed with RIP †¢ 180 sec is the hold down time †¢ Full updates are transmitted every 30 sec by each RIP router †¢ Works at network layer †¢ Prevent routing loops †¢ Hop limit †¢ incorrect routing  information are prevented from being propagated †¢ easy configuration †¢ no parameter required Two versions  of RIP are as follows: RIPv1: †¢ classful routing is used subnet information is not carried by periodic routing updates †¢ no support for VLSM (variable length subnet masks) †¢ Same network class have different sized subnet by the use of RIPv1 †¢ No router authentication †¢ Broadcast based and 15 is the maximum hop count A RIPv1 packet  format  is shown below: [pic]Fig: RIP packet  format Command:  determine whether  the packet  is  a request or  a response. A router send  all or part  of its routing table is asked by  the request. Reply  to  a request or regular routing update means the response. Routing table entries are contained in responses. Version number: RIP version used is specified. Potentially  incompatible versions can be signaled by this field.

Address family identifier (AFI):   The  address family used is specified. Address-family identifier is contained in  each entry  to  specify  the category  of  address being particularized. The  AFI  for IP  is 2. Address:   The IP  address is particularized  for  the entry. Metric:  The number of inter-network hops traversed  in  the trip  to  the destination is indicated. 1  and 15  for  an applicable route, or 16  for  an unapproachable route.

Route tag: The methodology is provided  for distinguishing between  internal routes (learned by RIP)  and external routes (learned from other protocols). IP  address: IP  address is particularized  for  the entry. Subnet mask:  The subnet mask is contained  for  the entry. No subnet mask has been particularized  for  the entry if this field  is zero. Next hop: The IP  address  of  the next hop is indicated  to which packets  for  the entry should be  forwarded. Metric:  The number of inter-network hops traversed  in  the trip  to  the destination is indicated. 1  and 15  for  an applicable route, or 16  for  an unapproachable route. 4. 2 OSPF (Open Shortest Path First) †¢ A Link-State protocol †¢ used  for routing between routers belonging  to  a single  autonomous system †¢ link-state technology is used †¢   information  about  the direct connections  and links is communicated between the routers Identical database is maintained by each OSPF router for the description of   the  autonomous System’s  topology †¢ Calculation of a routing table by the construction of a shortest- path tree from this database. †¢ Routes are quickly recalculated in the face of topological changes †¢ equal-cost multi-path are supported †¢ Authentication of all OSPF routing protocol exchanges †¢ Designed for TCP/IP environment †¢ routing updates authentication †¢ IP multicast are utilized in sending/receiving  the updates †¢ routes IP packets based exclusively on  the target IP  address originate  in  the IP packet header Grouping of sets of networks †¢ IP subnets are flexibly configured †¢ Destination  and mask is available to the route distributed by OSPF The following figure shows  the packet  format used by OSPF: [pic]Fig: OSPF packet  format Version number:  the OSPF version used is specified.

WORKING 5. 1 Distance Vector Routing: The following methods show  the overall working  of  the Distance-Vector Routing: . There is no predefined route i. e. entire route for a particular destination is not known to any router. The port to send out a unicast packet is known by each router on the basis of destination address. Progressively the route is made and there is the formation of the route by the contribution of each router when it receives the packet. The optimal tree is not predefined in DVRP actually. No routers have knowledge for making an optimal tree. Slowly and gradually the tree is made. The tree is formed as soon as a router receives a packet; it is forwarded by router through some of the ports, on the basis of source address. Other down-stream routers make the rest of the tree. The formation of the loops must be prevented by this protocol. Duplications are also prevented in order to make the entire network receive only one copy. In addition to this, the shortest path from source to the destination is the path travelled by a copy. Inconsistencies occurring with Distance-Vector Routing: Incorrect routing entries are caused by slow  inter-network convergence which may bring inconsistencies maintaining routing information. .  The following example describes how  inconsistencies occur  in Distance-Vector routing: The entire figure describes the inconsistencies occurring with Distance-Vector Routing. Defining  a maximum  to prevent count  to  infinity: . With this  approach,  the routing table update loop is permitted by routing protocol until  the metric exceeds its maximum  allowed value. Fig: Defining  a maximum  to prevent count  to  infinity 6 hops are defined as the maximum  allowed value. When  the metric value exceeds 16 hops, we cannot reach network 10. 4. 0. 0 Routing Loops  in Distance-Vector Routing: A routing loop is said to be occurred if two or more routers have  false routing  information  representing that  a applicable path  to  an unapproachable d estination exists via other routers. Fig: Routing Loop Solutions  to eliminate routing loops Split horizon:  The information is not sent in the direction from where original information comes. The split horizon function is illustrated by the following figure Fig: Split Horizon Route Poisoning:  Routing loops are eliminated. The following figure provides  an example  of Route Poisoning: Fig: Route Poisoning In  addition  to split horizon, route poisoning  and holddown timers, poison reverse, holddown timers  and triggered updates  are other methods  to eliminate routing loops. 5. 2 Link-State Routing: The following methods show  the overall working  of Link-State Routing. Gathering of the neighbor  information continuously. Router answering to this protocol are broadcasted the list of neighbor  information, process known  as flooding. Soon, this  information is distributed to all routers on  the network. Flooding of the neighbor  information in case  of  a (routing-significant) change  in  the network. The best path can be calculated to any host on any destination network as everything  about  the network is known by every router. 6.
