Layers of atmosphere: troposphere is closest to earth’s surface and contains 90% of mass of entire atmosphere. Stratosphere has the ozone layer that absorbs UV rays from sun and protects life on earth. Mesosphere is the coldest layer of the atmosphere. The mesopause is the boundary between mesosphere and thermosphere. Thermosphere is the last layer of atmosphere and it is warmer than mesosphere and has a little O2 and has a layer of ionized gases 9. Waste created by coal power plants: heat to troposphere, CO2 and air pollution 10. Pros and cons of coal power: pros- ample supply, high net energy, low cost, well developed mining and combustion technology, air pollution can be reduced with improved technologies.

Pros and cons of nuclear power: pros- large fuel supply, low envir. Impact, emits 1/6 as much CO2 as coal, moderate land use and disruption and water pollution, and Low risk of accidents. Cons- expensive, low net energy yield, catastrophic accidents, no solution for radioactive waste storage, terrorist attacks, weapons 12. Source of radon: some soil and rock 13. Tropospheric ozone: air pollutant, bad ozone because it can damage living tissue and break down certain materials 14. Acid rain: caused by coal burning power plants, ore smelters and industrial plants that use tall smokestacks to emit SO2 and NO2 into troposphere. Consequences: 2-14 day persistence, ruins sensitive soil, worsens respiratory disease, attacks metallic and stone, decreases atmospheric visibility, kills fish, depletes soil of vital plant nutrients and harms crops and plants. Solutions: improving energy efficiency, reduce coal use, increase natural gas use and renewable energy resourcs, burn low sulfur coal, remove SO2 and NO2 from smokestack gases, remove NO2 from motor vehicular exhaust, tax emissions of SO2, add lime to neutralize acidified lakes and add phosphate fertilizer to neutralize acidified lakes. pH of rain: 5.6 or less. Problem in eastern US. 15. Greenhouse gases and their sources: water vapor, CO2, CH4, NO2, O3. Sources are burning fossil fuels, electricity production, transportation, industry, commercial and residential, agriculture, land use and forestry. 16.

O3- coughing, breathing problems, reduces resistance to colds and pneumonia, irritates eyes, nose, and throat, aggravates asthma, bronchitis, emphysema and heart disease and damages plants, rubber in tires, fabrics and paints. Particulates- irritate the nose and throat, damage lungs, aggravate asthma and bronchitis, shortens life. Lead- mutations, reproductive problems, cancer, nervous system damage, mental retardation and digestive and other health problems, reduce visibility and corrode metals and discolor clothes and paints. 29. CERCLA: requires parties responsible for creating a hazardous waste site to be responsible for its cleanup 30. NAFTA: goal to eliminate barriers to trade and investment between US, Canada and Mexico to eliminate tariffs on more than  ½ of Mexico’s exports to the US. Try to pressure countries to improve envir. Protection mechanism 31. Electrostatic precipitators: to remove particulates, after they are in smokestack gas, it gives them a negative charge, they are attracted to a positively charged precipitator wall and fall off the wall into a collector, they maintain and remove 99% of particulate, but use a lot of electricity and do not remove hazardous ultrafine particles and produce a toxic dust that must be disposed of safely. 32. Alternatives to chlorine in waste water treatment: microfiltration, ultrafiltration, ion exchange

Human Resource Professional Essay

Activity 1 The Human Resource Professional (HRP) Map displays a clear idea about the required HR skills, knowledge and behaviour to lead the organization to successes. The HRP Map covering of 10 professional areas, 8 behaviours and 4 bands. Sarah Miles (2009), CIPD organizational development director, said: â€Å"This is a complete rethink of professional standards, not just a simple face-lift, and that’s not something you can turn around in a short time. † Human resource professional areas describes what HRs need to know (knowledge) and what need to do (Activities) at four bands of professional capability in each HR professional area. The core professional areas of the HRP Map are Strategy, Insights and Solutions and Leading and Managing the Human Resource function. These are necessary for HRs in their main roles either in organization or in developing themselves. Remain eight professional areas as follows: employee engagement, employee relations, learning and talent development, organization design, organization development, performance and reward, resourcing talent planning and service delivery information. The Strategy, Insights and Solutions by using deep accurate thoughtful of the business activities, plans and strategy and fundamental encouragement of and difficulties to perform sustainability with the need of customers and unique insights to grow the performance of the business through establishing and delivering of human resources solutions and strategy. The Leading and Managing the Human Resource function by guiding and organizing customized human resources function depend on the need of the business requirements. Guarantees that the function has the exact capability, capacity and organization plan in which human resources employees are engaged, work team base and have deep understanding of organization with the drivers valued results. An HR professional needs to carry out the activities through some behaviour. Each behaviour is explained at the four bands of professional capability and lists a number of contra indicators which show negative behaviour. They are 8 which are collaborative, courage to challenge, curious, decisive thinker, driven to deliver, personally credible, role model and skilled influencer. My own selected professional area is the need to improve organization Development for Native Consultancy, Information Technology Company. The Activates, knowledge and behaviour at Band 1 which are most essential to my own HR role are in three points: * Knows employment law and discrimination law, in local and international rule and what the organization needs to do to prevent and monitor the risks. That can be done through collects, assembles and accurately analyses measures, data and feedback by using Labour law book, experts in local and international rules, and register in Labour law course. Respond to change in different ways for different cultures. Through promotes the organizational values and behaviours and recognises their interdependencies with organisational processes, structures, and ways of working. Read relevant researches, meetings with different culturally customers. Satisfy the customers with well communication skills. * Understands basic Organizational Development analytical tools and how to use it correctly. Co-ordinates and rolls out internal communication messages. By reading Articles, researches and case study about Organizational Development and its tools. Easy to apply the OD tools and uses one of it in the organization. The leading behaviours that are essential for this professional area to be done are driven to deliver – expresses willpower, creativity and reason to deliver the best results for the organisation, collaborative – Works efficiently in both inside and outside of the organisation with a range of people. And curious – Is curious and open-minded; seeks out innovative ways to add value to the organisation. Activity 2 To understand the needs of the customers and level of satisfaction, the HR have to continually monitor the needs and how it has been meeting those needs and recognaize any areas that has gaps. This way of analysis will find out the real view of the customers’ needs and will guide the HR professional to balance several perspective and determining which get priority. â€Å"For instance, managers may value high levels of production and long work hours whereas employees may value more time off and a focus on work/life needs. Effective HR customer service will work with both groups to find the right balance† Leigh Richards (2012), eHow Contributor. The customers verify in two types, internal and external. Here we will consider the internal customers for its direct effects on the company and its ongoing processes as employees, managers and technicians. Their needs are differ as training, reports, CVs, tools and hardware and sometime conflict with others. In the divergent of the customers need; the HR professional have to take accurate and impartial clear decision on that. The HR choice will depend on the most important and effective on the organization in a timely manner as the training in the development of new strategy or plan before other needs. To communicate effectively in the organization between customers; e-mails, chats (WhatsApp/BlackBerry/Skype) and direct phone calls are most useful. E-mails are used as formal communication tool between different customers and can be archived for future need but it can be a reason to delay the response either by the user or by telecommunications’ problems. Otherwise the chats and calls can retrieve with direct reply and helpful for urgent issues but as usual cannot be used later for its instantly unsaved answers. An effective work relationship with employees leads to a positive environment. The colleagues, supervisors and management will respect the decisions and contributions results from a collaborative team. â€Å"Maintaining an effective relationship with co-workers takes effort, such as regular communication† Cherrine Banks (2009), the eHow Contributor. Key to any successful HR-line manager relationship is communication. Although the structure of HR is important, success is more about the relationships you build with line managers. Any particular structure that is working now, is reviewed to ensure the HR framework continues to support them,† La Penna (2007). Complaints are found in every organization and business. The most common solutions are Listening, Solving and being polite. Firstly listening to what the customer has to say and ask for as many details as possible. Classify the problem. Then offer a solution before other requests one within a clear policy to know how far you are willing to go for solving the complaints. Be thankful and polite while listening and solving the problem. Be careful on the tone used and body language to solve the problem effectively. Difficult employees display behaviors that can be uncomfortable and backfired to the goals of the organization. The behaviors of a difficult employee can range from stable conversation to rejection to complete the job tasks and its responsibilities. Other difficult behaviors include neglect of colleagues and waste of company belongings. It is important for managers to identify, walk in and stop the actions of difficult employees before more harm is done. How difficult a person is for you to deal with depends on your self-esteem, your self-confidence and your professional courage. † Susan M. Heathfield (2011), Human Resources expert and covered Human Resources for About. com since 2000. HR professional has to explore and brainstorm some solutions with a trusted experienced friend or colleague. Approach the person whom having the problem with private and open a discussion with agreement toward positive actions. The Following up is essential with this person. If the difficult customer didn’t changed positively, the transferring process to new department or job within the organization will be helpful. Time is main effective factor for providing services. Commitments with the deadlines and within the organization roles will effects it toward success. Some services are depending on each other in prioritized and sequence way; so it have be done carefully with respect to the start day and the duration without any dely. Once time is left, the process of finalizing the work have to be faster and will affect other tasks and maybe will consume more recourses, time and money. Dearing the current situation of market, the organizations cannot afford everything needed for the customers. The budget has shortage and the business is returning less profit than before. From that point, the HR practitioner can handle the customized budget in smart way. As purchasing printer one for each department and can be non-colour printing for all except those in need for colour as advertisement department. As well the printing can be converted to be digitally e-mailed or uploaded to the organizations website. Brad Power (2011) writes about this in â€Å"Why Doesn’t HR Lead Change? He defers to Dave Ulrich, a University of Michigan professor recognized by HR Magazine as the most influential person in HR, who said there are three human resources processes that are critical to embedding a culture of continuous improvement: talent flow, rewards and training and development. Firstly, for the talent flow, HR experts can develop method for hiring who are familiar with the attitudes and behaviors of their company. Managers are hired for expertise, not attitude and behavior. The attitude and behavior that support the direction of the company are necessary to continues improvement. The Rewards is a â€Å"Continuous improvement demands that people not only carry out their jobs, but improve their work too,† writes Power. Training and Development is important at the organization. If it does not afford the knowledge and skills customers need to improve their work, its mean that continuous improvement isn’t important. According to the power for leading change, HR professional must use its influence to help leaders focus on customers, long-term business outcomes, and building competences in their people; be a partner; and get operational experience.

Case study Example | Topics and Well Written Essays - 1000 words - 7

Case Study Example The only lacking portion is the enforcement of strict sanctions and rewards mechanisms which would ultimately deter the employees to even consider bribery or manifesting corrupt behavior. 2. The steps instituted by Siemens Global to root out corruption is already extensive and comprehensive. As noted, there must be a system of rewards for compliance and sanctions for non-compliance. Likewise, since there is an aspect of cultural element that have considered bribery as part of their organizational culture, there should be vigilance and regular monitoring of the performance of all employees regarding conformity to the zero-tolerance policy through performance appraisals, random checking, and imposition of stricter penalties for violations, as deemed necessary. 3. Yes, one strongly believes that given the massive scale of previous corrupt transactions that involved billions of dollars through the years, the financial penalties were merely about 3.75% of their 72 billion annual sales, which was not even commensurate to the usual percentages (a minimum of 5 to 6% of the contract’s value to a maximum of 40%) accorded to bribery in their previous dealings. Therefore, they should have been imposed additional financial penalties to hurt so much that they would not ever consider bribery and corruption in current and future undertakings. 4. Siemens can therefore move beyond compliance to develop a healthy ethical climate by being more vigilant and ensuring through frequent monitoring, training, and performance evaluation that all employees and officers comply with the zero-tolerance policy. A code of ethical behavior should be integrated as part of their organizational policies. Only through a system of regular check and balance, as well as conformity to transparency and accountability, would Siemens Global be able to regain an ethical culture that

The Enduring Value of History Assignment Example | Topics and Well Written Essays - 2750 words

The Enduring Value of History - Assignment Example The history of modern art dates back to 1880. Modern art broke from the restrictions of realism in art that was the norm in those days. Modern art embraced a subjective representation of real life objects. Modern artwork is more inclined to looking inwards and artists seek to portray the evolution of their subject over a period of time. According to Gregory, this form of art was targeted at showcasing the evolution of ideas over time and the impact of the society . Modern art evolved over time to present the changes in the society. Impressionism was the first form of modern art that deviated from the traditional aspects of art. The modern artists who practiced this style focused majorly on recreating the scene of the art and appealing to the emotional aspect of the painting. Cubism was more inclined towards finding strong forms for art work instead of just squares. The composition of the artwork was given prominence and primitive geometric shapes were not prioritized. The most vital aspect of modern art that is relevant to the requirements of Apperception is the use abstraction. Abstract art focuses on a feeling of thought that cannot be quantified and not necessarily a recognizable object. The paintings that applied this style showcased several layers of abstraction. The importance of this abstraction is that it spurs the mind to generate interpretations of the painting in several unique ways . It’s a possibility to have a unique interpretation of the painting each time that he sees it.

Personal Statement Example The knowledge obtained by combining management and financial study is essential as it facilitates the development of strategic decisions. At the same time, the two disciplines ensure effective adoption and implementation of policies and plans aimed at achieving the organisations objectives. Asset allocation is one of the fields where management and financial strategy are often intertwined. This investment strategy involves creating a balance between risk and reward by adjusting the percentage of an asset. Therefore, critical thinking that is a skill obtained in management is significant in determining business’s risk tolerance, goals and investment time frame (Pandey 2009:70). Moreover, the external environment is often bombarded with issues such as inflation. Inflation is a current issue that can cause significant distortions in the economy. A market that is experiencing inflation discourages savings, reduces economic growth and can discourage investors. Management cannot rely on their knowledge regarding the market. Therefore, management would be expected to conduct research on the environmental forces that would affect its resources and thus inhibit the achievement of the set objectives. When it comes to inflation, management is expected to utilise its financ ial tools so as to come up with an effective financial strategy that would ensure the firm’s success. Studying finance is important as it enables a manager to ensure proper allocation of money. The business operates in a financial environment in which there are a constant inflow and outflow of money. Without proper financial management, a firm would be unable to account properly for the financial resources available. For example, if a small business took a small loan and used it to finance its fixed assets. The short loan is a liability that has to be paid back within one year. However, the firm may find it difficult to sell the assets within one year. The company may find itself unable to pay

Disability and Its Everyday Use Dissertation Example | Topics and Well Written Essays - 3000 words

Disability and Its Everyday Use - Dissertation Example Disability is considered as a curse or a characteristic of poverty in some third world countries, but it is treated as a normal medical condition in some First the World countries. Bangladesh is also another developing country with serious cases of disability and poverty. The country records one of the highest levels of disability rates in the world. 16% of the country’s population has disabilities (Mitra et al, 2011). The highest percentage of people with disabilities in Bangladesh is made up of women (23% compared to 10% for men). Disability prevalence is higher in poor countries than in rich countries. People with disabilities in Zimbabwe, Bangladesh and Burkina Faso also have a lower level of educational attainment and low employment rates (Eide & Ingstad, 2011). Disability is considered a curse or a characteristic of poverty in some third world countries, but it is treated as a normal medical condition in some First World countries. Bangladesh is also another developing c ountry with serious cases of disability and poverty. The country records one of the highest levels of disability rates in the world. 16% of the country’s population has disabilities (Mitra et al, 2011). The highest percentage of people with disabilities in Bangladesh is made up of women (23% compared to 10% for men). Disability prevalence is higher in poor countries than in rich countries. People with disabilities in Zimbabwe, Bangladesh and Burkina Faso also have a lower level of educational attainment and low employment rates (Eide & Ingstad, 2011). Disability affects millions of families in third world countries. About 650 million people around the world currently live with the disability, amounting to around 10% of the world’s total population (Mitra et al, 2011). Around 80 percent of the total number of people with a disability lives in third world countries. Disability is more common in poor communities than rich communities (Eide & Ingstad, 2011). While the tota l population of people with disability is only 10 percent of the world’s total population, the percentage is 20 percent among the world’s poorest communities. Developed or industrialized countries have adopted laws and practices to protect the rights of people with disability. For example, U.S.A. has anti-discrimination laws which allow people with disabilities to have access to work. The U.S.A. also has a large number of people with disabilities who own small businesses. Some companies in the United States and other developed countries also have disability management programs in the workplace. Furthermore, disability benefits and insurance programs are provided by employers in U.S.A as required by the law. However, U.S.A. still records a large number of people with disabilities without work. Employers argue that people with disabilities are not able to perform the required tasks effectively.

Issues associated with use of force on inmates Essay

Issues associated with use of force on inmates - Essay Example The law in the country establishes the rights to an inmate. The following are some of the rights. For one, they have the right to trial. This is because not all inmates breach the law. Second, they have the right for treatment with respect. Third, they deem for the right to a legal counsel from a legal representative. Third, they deserve the right to a range of reading materials (Barkan & Bryjak, 2011). Other rights include-right to nutritious meals, to take part in enlightening programmes, and the right to get information of the rules, procedures, and schedules concerning the operation of each detention activity. Further, they have the right to communicate with family members. The reasons why inmates should have the above rights are that they are human beings requiring what others have. Second, some are not necessarily criminals as there are suspects amongst criminal offenders. The punishment on an inmate by personnel is very different from that on a suspect by police. This is due to various distinguishing reasons. Police use force when arresting individuals, and when dispersing demonstrating groups. They do this through pushing the individuals, or using firearms. On the other hand, personnel use force on inmates when they want the inmates to partake a certain job, and when punishing the prisoners. It is a difficult to deal with people of an older age. The police may use certain devices when dealing with people and in different scenes. They use tasers, and stun guns to determine the time a certain shot takes place and aids in dispersing people. They are effective in that the police get to know the time of the shooting. An advantage is that they help astonish assailants at a distance. In addition, the use of tasers is a way of conducting current over longer distances. Several lessons come out from the essay. It is evident that inmates have their rights despite them being lawbreakers. The police and other security personnel should not

CF&F Employee Survey Essay Example | Topics and Well Written Essays - 750 words

CF&F Employee Survey - Essay Example It also involves diagnosing those areas where employees are likely to be most sensitive to change. All of these factors for overcoming resistance to change can be achieved through a well-devised and thoughtfully implemented employee survey. The survey that is outlined within this document is designed to determine the extent of employee engagement with the organization in its current state, as well as how engaged employees would feel if certain changes were implemented. Ideally, the survey would be administered by the company's human resources department so that all employee levels could participate objectively. Indeed, resistance to change can certainly be prevalent at every level - from front line workers to senior management. In this case, many employees and managers have a vested interest in the established culture and do not want to see any changes. Nepotism has been identified as a significant problem within the organization; and there is a growing resentment of management among hourly workers due to the authoritarian manner in which they have been managed. Moreover, the level of concern for regulatory compliance is unacceptably low, an attitude that has trickled down from management to the hourly employees. Please select the number that corresponds to your level of ... 1 2 3 4 5 My immediate supervisor cares about my success. 1 2 3 4 5 There is a direct relationship between my work and the company's success. 1 2 3 4 5 I have an equal chance of advancing within the company to any of my co-workers. 1 2 3 4 5 I am fairly compensated for the work I do in my company. 1 2 3 4 5 I share some responsibility for ensuring the company operates ethically and legally. 1 2 3 4 5 My company cares about my individual opinion and needs. 1 2 3 4 5 My company has provided me with the resources I need to do my job effectively. 1 2 3 4 5 I would recommend my company as a place of employment to friends and associates. 1 2 3 4 5 I am confident in my company's senior management. 1 2 3 4 5 My company needs to make changes in order to ensure future success 1 2 3 4 5 What is your job function: 1: hourly worker 2: frontline manager 3: mid-level manager 4: senior manager Results and Communication of Findings The survey is likely to show that hourly employees are relatively unhappy with the present state of the organization as compared to the managers. They will probably be more likely to indicate a lack of connection between their own success and that of the organization. They will probably also disagree with the statement that management cares about their success, and that they have an equal chance for advancement within the organization as compared with their coworkers. Hourly employees will be more likely than managers to indicate that the company needs to make changes. Managers will express a higher level of confidence in senior management than will hourly employees; and they will likely feel more fairly compensated for their work. All levels will express some level of

Art & Humanities - Essay Example Through a critical analysis of Nickelback's hit single, Rockstar,' this essay shall try to establish that while the behavior of rockstars and rock bands is often supportive of the most negative of the stereotypes surrounding the genre, the music and lyrics particular to rock often have a profound message to communicate, one which directly ties in to the dreams, aspirations and fears of the youth. Nickelback is a stereotypical bad, wild boy rock band. The Canadian band, which made its first appearance on the music scene in 1995, is comprised of Chad and Mike Kroeger and Ryan Vikedal. Over the past twelve years, the band has attained popular success, with global sales of approximately 25 million albums and several Juno, MTV, American Music and World Music awards (Jennings, 2002) but has repeatedly aroused criticisms and controversies regarding the behavior both on and off-stage. While in concert in Portugal in 2002, the band members fought with and insulted audience members before walking off stage, refusing to come back on again. They were subsequently criticized as unprofessional and unreliable, in addition to which they lost a significant percentage of the European fan base as a result (Jennings, 2002). Association with excessive drug and alcohol use has not helped the band's image (Rendon, 2005). Objectively speaking, Nickelback's on and off-stage antics and behavior has furnished additional support for rock music's critics and, indeed, appears to further evidence the popular conception of rock music and musicians as decadent and a corrupting influence. As this appears typical of most rockstars, Kizis (2001) theorizes a link between the genre and the behavior of its stars. The genre is, by definition, a declaration of rebellion against customs and traditions, and embraces a rejection of what is typically regarded as music. Singing becomes shouting, melody becomes dissonance and the identification of rhythm is an often daunting challenge. Rock music is a rebellion, an uprising against musical conventions and rockstars are, by the very virtue of their adherence to, and association with, the genre, rebels against traditional and conventions, against norms and mores. In other words, just like the genre itself, the behavior of rockstars is a cultural statement and a declaration of refusal to be bound by conventions. Nickelback is no exception. Apart from the statement of rebellion which Nickelback expresses through both behavior and chosen genre, the band has something to say and their name is evidence of this. As explained on the band's official website, the band members are all from very modest backgrounds but had hopes of succeeding through their music. From the outset, however, they were determined that their success, if they ever attained it, would not make them forget their roots and their reality. The band's name serves as that reminder because it recalls the members' origins as employees of a small coffee shop when their only words to customers were "here's your nickel back" (Nickelback.com). The band's name derives from this and, at one and the same time, expresses both its members' originality and determination to remember, even when at the peak, their origins and, thus, their reality. The band's name, in other words, signifies a connection with its members' roots. Just as the band's name functions as a

Pros and Cons of Nuclear Power Essay Example for Free

Pros and Cons of Nuclear Power Essay The release and development of the enormous energy potential locked in the atomic nucleus signified a key revolution in scientific research in the 20th century. With great potential and optimism of developing a pollution free unlimited supply of energy, nuclear technology was ushered into the 21st century where it has become embroiled in unending debates. Nuclear power is a clean source of energy, the raw material is sustainable and the magnitude of power output is extremely large and efficient. Opponents have been quick to recount the costs of initial investment, the risks and safety loopholes and the more fearsome proliferation of nuclear weapons as the major detriments to exploitation of nuclear energy. This paper offers a succinct and informed analysis on the cons and pros of nuclear power exploitation and the potentialities that exist in the future exploitation of nuclear power. With genuine interest and adherence to rigorous and stringent constraints, safety in design and construction and global informed decision making, the setbacks to nuclear exploitation can be effectively ameliorated. In classical thermodynamics, energy is the capacity or ability to do work. Practically, energy is the major driving force of development in post modern civilizations. Energy is the main ingredient to economic, social and political prosperity. Gradual increases in demands of energy for production purposes has put a strain on non renewable sources of energy such as fossil fuels; the most predominant sources of energy(Richardson, 1996). Decreases in oil, natural gas and coal reserves have prompted a paradigm shift to other forms of energy such as wind energy, solar energy and nuclear power to help replenish energy shortages as well as create a reserve for growing industrial energy demand(Nersesian, 2007). Increasing global energy demands and environmental pollution coupled with the prospect of declining and eventual depletion of non renewable energy resources is the sustainable incentive towards to exploitation of a clean, more efficient and sustainable energy solution to meet the global demand. Even though solar energy and wind energy present a cleaner more sustainable energy option, the magnitude of global energy demand can only be offset by nuclear power production(Conant, 1979). In simple terms it takes a certain amount of energy to make another form of energy. Combustion of oil produces a certain amount of energy that is much higher than when coal undergoes combustion. Nuclear energy consumes the least amount of fuel energy to release a huge out put of electricity(Nersesian, 2007). This makes nuclear power the most cost effective form of power production and it does not contribute to environmental pollution so long as the nuclear waste is disposed off according to compliance standards, the risk of radiative exposure is reduces through installation of security measures(Dell et al, 2004). In this era of climate change and global warming, nuclear power; a green energy source is a godsend necessary to limit and considerably reduce the release of green house gases and other toxic elements into the atmosphere and the ozone layer. In 1977, the Kyoto Protocol negotiated by the Framework Convention on Climate Change(FCCC) agreed in principle to institute steps aimed at the reduction of green house gases. The center piece of such a resolution undoubtedly rested on the transformation from non renewable sources of energy to renewable sources of energy. Only fission, wind solar, decarbonized fossil fuels, wind and biomass have the capacity to provide a steady supply of carbon free energy. To a large extent only fission energy is commercially feasible and cost effective, the other have significant economic and technical handicaps. Nuclear energy remains the only viable option that can be fully exploited to reduce green house gas emissions to near minimum emissions while maintaining a reliable and consistent supply of carbon free electric energy supply to meet the world energy demand(B. van der Zwaan et al, 1999). Apart from the initial capital investments involved in construction, monitoring, insurance and decommission, nuclear power production is relatively inexpensive. Uranium; the raw material in nuclear reactors is less expensive than any form of fossil fuel. Because subsequent production costs are reduced, nuclear power is a less expensive source of electricity. The magnitude of energy produced makes it more reliable and consistent energy source. Other sources of renewable energy supply are so limited as to be of very little economic benefit. For this reason countries are extending the lifespan of older nuclear reactors while constructing new ones. This has led to a progressive reduction in the costs incurred in nuclear energy production. There are more specific reasons that attest to this trend. Countries have succeeded in developing and adopting a more superior choice of nuclear technology, efficiency in construction and operation management, low costs of decommissioning in the United States and Western Europe have ensured that green technologies like nuclear power become the future global energy solution(Griffin, 2003). Despite being one of the most efficient energy production technology, nuclear power production is plagued by a myriad of issues. Some of these issues are ,specific in nature but a majority are basically non specific and are manly driven by lack of adequate technical and scientific know how or even fear . Specific issues revolve around licensing regulations and safety. Safety concerns are ideally resolvable and include fatigue of the piping system in much older plants, fire protection system, issues that concern the degradation of the reactor pressure vessel as a result of neutron irradiation. Those opposed to the building of more nuclear power plants advocate for an uprating of the power output of those plants that are currently in operation(Angelo, 2004). Global terrorism is putting more strain on the regulation of nuclear production for fear of proliferation of nuclear weapons in unstable states and the acquisition of nuclear production knowledge by extremists , fundamentalists and terrorists or suicidal fanaticism(B. van der Zwaan et al, 1999). However, such fears are obviated by the defense in depth philosophy employed in the design and construction of nuclear power production facilities. Nuclear plants are primarily designed to protect the public from radiation exposure. For terrorists to attack such plants then it would mean that their primary aim is not to cause mass civilian deaths but sabotage the power production. Moreover, these facilities have a vehicle barrier systems designed to deter against truck bombs. Advanced security systems cordon off restricted areas from any form of intrusion or unauthorized entry. Nuclear facilities are immune and more resistant to aerial attacks than any other civilian security or energy installation. After the September 11 attacks, the United States government installed additional protection measures and carried out studies to determine the extent of damage to a nuclear plant should it be struck by a large aircraft as in the World Trade Center attacks. Results affirmed that no considerable damage was envisioned because such an explosion would not be able to penetrate and affect the nuclear fuel or even penetrate into the nuclear facility to cause any radiation release(Angelo, 2004; US National Energy Council, 2003). Nuclear accidents and safety issues have remained to be the most pressing, highly visible issues because accidents generally release nuclear radiations that affect the general public. Nuclear facilities are required to completely prevent radioactive release into the environment. Fear of potential exposure to radiations is still being propelled by two notable nuclear reactor accidents. In 1979, the Mile Island accident in the United States caused severe destruction to the facility although no external human or environmental health was recorded. This was only possible because the reactor had installed a safety containment vessel. In 1986, the Chernobyl nuclear plant in Ukraine accident caused disastrous human and environmental effects. Lack of a safety containment vessel, glaring human errors and poor reactor design was to blame for the extent of the destruction. 31 employees and emergency response personnel lost their lives from acute radiation sickness. The environmental consequences were spread throughout the Soviet Union. Effects were also felt in parts of Europe and even across vast regions of the Northern Hemisphere (Angelo, 2004). The facts behind the detrimental effects caused by the Chernobyl nuclear reactor accidents pointed to gross design and operational defects(Evans, 1984). Such defects are not applicable to modern nuclear reactors that undergo rigorous and stringent compliance tests but the Chernobyl accident still drives popular misconceptions that emanate from nuclear neurosis or radiation phobia as some psychologists prefer to refer to the misconception syndrome. However, issues about nuclear safety should not be stashed aside and the status quo in safety left to reign. Safety in nuclear energy production should be a continuous improvement exercise because radiologic accidents inflict profound psychosocial impacts along and across the societal strata. Emergency response and evacuation mechanisms are a prerequisite to any operating reactor plant. The trends of evacuation and health care assistance in the aftermath of a reactor accident is a determinant of the level of psychosocial impacts that will manifest in the society long after the accident. Disorderly evacuation, panic driven movements by the surrounding community and general public panic stimulate unwarranted societal anxiety. It is these impacts that tend to propagate indecision on the level of safety a nuclear plant can attain(Foreman, 1970). Economically, nuclear energy production costs are comparatively lower when compared with other sources of energy. However, initial investment capital is enormous(Kursunoglu et al, 2000). The costs incurred in construction, monitoring, insurance and decommission are extremely high hence creating opposition to investments in nuclear power(Domenici, 2007). Because the efficiency of nuclear energy is not under any doubts, a broad based strategy program is essential to ameliorate the concerns about initial cost of investments, risks involved in energy production, waste disposal problems and the fear of proliferation of nuclear weapons. Conclusion Recent developments in the nuclear technology and the continuing threat of nuclear warfare has stimulated fresh intellectual debates on the benefits of nuclear technology to the existence of mankind. Even when used for civilian production of energy, nuclear technology conjures up a real threat to world peace the oldest wish for humanity since the onset of human civilization. Nuclear power is the most potent force for human annihilation and it gets even more scary when such a tool is placed is accessible for suicidal fanaticism. When used unwisely, it may prove to be a deadly weapon that is capable of trashing human civilizations and making real the undying fear of nuclear apocalypse. Regional nuclear warfare and nuclear nuclear terrorism can only be forestalled or completely eliminated when humanity works together for a common purpose that is beneficial to each and every head on the surface of this earth. Human beings have an innate responsibility to do all in their power as human beings to use nuclear technology to advance the cause of modern civilization in power generation, medicine, agriculture, research, industrial applications and space exploration. Nuclear power should be harnessed properly with the genuine cause of building a sustainable planetary civilization that spans beyond the ends of the earth into the uncharted territories of the solar system. Rigorous and stringent constraints, safety in design and construction and a global informed decision making is a prerequisite to nuclear power exploitation. References Angelo, A. Joseph. (2004).

Response to Shooting an Elephant Essay Example for Free

Response to Shooting an Elephant Essay George Orwell, one of the most famous English authors, was born Eric Arthur Blair in Motihari, India, in 1903. His father was a colonial official for the British and his mother’s family also had colonial ties. In 1922, Orwell worked as a British imperial policeman in Burma for five years but he finally returned to England again because he recognized the injustices of the British imperial rule in Burma and could not suffer the guilt of oppressing the Burmese anymore. Later, Orwell spent the next twenty years as a writer; the essay â€Å"Shooting an Elephant,† set in the Burma of the 1920s and written in 1936, is one of his most famous works. In the early twentieth century, Burma was still a colony of Britain but anti-imperialism protests and social movements developed very fast, causing â€Å"great tension between Burmese, Indians and English, between civilians and police† (Meyers 56). Orwell’s essay â€Å"Shooting an Elephant† is based on this historical tension. In this essay, Orwell depicts an older narrator recounting his imperial policeman’s experience of killing an escaped elephant that destroyed a market and killed an Indian man in Burma. Throughout the story, Orwell chooses language carefully to develop his narration so as to help the readers explore a young imperial officer’s emotional struggle. First, Orwell begins his story with frequent use of carefully-chosen diction to indicate the young policeman’s hatred and also sympathy toward the Burmese. When he describes he was always â€Å"an obvious target† to those Burmese who hated the British Empire, he writes: When a nimble Burman tripped me up on the football field and the referee (another Burman) looked the other way, then the crowd yelled with hideous laughter. This happened more than once. In the end the sneering yellow faces of young men that met me everywhere, the insults hooted after me when I was at a safe distance, got badly on my nerves. (Orwell 94) Using the strong emotional words â€Å"hideous,† â€Å"sneering yellow faces,† and â€Å"hooted† indicates the young officer’s disgust toward those Burmese. But in the following paragraph his emotions are suddenly described in a more complex way; the narrator says, â€Å"All this was perplexing and upsetting† (Orwell 94), which is opposite to the anger and bitterness that are suggested by the diction used before. By using these two words, Orwell changes the young policeman’s emotional voice to the older narrator’s more intellectual voice to suggests a more complex feeling about what the young imperial policeman experienced because of his job. In the next sentence, Orwell uses a series of strong phrases to describe what the young police officer observes in his â€Å"dirty work†: â€Å"The wretched prisoners huddling in the stinking cages of lock-ups, the grey, cowed faces of the long-term convicts, the scarred buttocks of the men who had been flogged with bamboos—all these oppressed me with an intolerable sense of guilt† (Orwell 91). From this specific and graphic description of the prison, readers can perceive the young officer’s sympathy and guilt toward the suffering Burmese. It makes them realize that the young imperial officer is not totally inhumane. In short, Orwell uses careful diction to create the first emotional struggle of the young officer within his policing duties under imperialism. In the essay, Orwell also uses repetition to show the young narrator’s complex emotions. For example, after the young officer sees the destruction caused by the elephant and finally finds his target on the paddy field, he mentions more than three times that he is not willing to shoot the elephant. When he sees the crowd following him, he reports, â€Å"I had no intention of shooting the elephant—I had merely sent for the rifle to defend myself if necessary†(Orwell 94). After he sees the elephant, he comments, â€Å"I knew with perfect certainty that I ought not to shoot him† (Orwell 94). Then, he starts saying that the elephant was â€Å"a huge and costly piece of machinery† (Orwell 95) and the elephant seemed harmless right now. The young officer continues claiming,â€Å"I did not in the least want to shoot him† (Orwell 95). These all shows the young man’s sympathy toward the elephant, but more importantly Orwell builds up a tension here by using three different versions of repetition to show how the young officer was wavering in his position. For the first quote, â€Å"no intention† somehow indicates the young narrator’s thinking: he seems to be saying, â€Å"I have no purpose to do that and I am not going to do it. † But then in the second quote, he says â€Å"ought not to† instead of â€Å"no intension of,† which contains much more certainty of not killing the elephant. It shows that the young officer knew he should not shoot the elephant, but he certainly felt a lot of pressure and his mind was not as firm as in the last statement. In the third statement, the young officer’s tone is obviously weaker than the last two; â€Å"I did not in the least want†¦Ã¢â‚¬  this tone sounds just like a prisoner talking about how he does not want to commit a murder, finishes it saying â€Å"I didn’t want to kill that person. † The young officer’s mind was wavering and he was taking a step forward toward killing the elephant everytime he introduces his different expressions of unwilling to kill the elephant. Orwell uses this repetition not only to show the young officer’s internal conflict, but also to imply, as a possible result, that the young officer will change his mind from not shooting the elephant to actually doing that. However, under the crowd’s pressure and his position as an imperial officer, the young police officer has to kill the elephant in order to maintain his master figure. Orwell uses the change from the first person to the third person to comment on the young man’s revelation. When the young man sees that the Burmese watch him excitedly, he suddenly feels that he should shoot the elephant after all. And it is because â€Å"their two thousand wills [were] pressing me forward, irresistibly†¦[that] I perceived in this moment that when the white man turns tyrant it is his own freedom that he destroys. He becomes a sort of hollow, posing dummy, the conventionalized figure of a sahib† (Orwell 95). The narration shifts from the first person â€Å"I† to the third person â€Å"he,† indicating not only Orwell’s comment upon this decision of the young person, but also Orwell’s main argument in the essay: as a imperial officer, a person needs to betray his own good nature in order to maintain his superiority toward the colonized. Then, Orwell uses strong terms again to replay the emergency and tension that the young officer encountered earlier: A white man mustn’t be frightened in front of ‘natives’; and so, in general, he isn’t frightened. The sole thought in my mind was that if anything went wrong those two thousand Burmans would see me pursued, caught, trampled on and reduced to a grinning corpse like the Indian up the hill. And if that happened it was quite probable that some of them would laugh. That would never do. (Orwell 96) Here, words like â€Å"sole thought,† â€Å"trampled,† â€Å"reduced to a grinning corpse† are used to emphasize the young man’s anxiety in shooting the elephant, for he does not want to lose face in front of the natives. This is the remaining emotion occupying his mind at that time; even though he still has sympathy toward the elephant, as a imperial officer, he will kill the elephant to protect his â€Å"conventionalized figure of a sahib. † By way of these specific word choices, Orwell describes vividly how the young imperial officer’s pride finally defeats his good nature so that he can maintain his superior figure. Finally, Orwell ends the story using the young officer’s naive voice as opposed to the older narrator’s voice mentioned before to make his narration more believable: â€Å"I was very glad that the coolie [which is the Indian killed by the elephant] had been killed†¦it gave me a sufficient pretext for shooting the elephant† (Orwell 99). Readers may feel sympathetic that the young man does not feel guilty but happy that he is not responsible for killing the elephant and saving his face or â€Å"avoiding looking a fool† in front of the natives. They may feel pity that the young man is likely to learn nothing from this incident and even to feel lucky that someone’s death can free him of responsibility for killing the elephant. But this naive voice can increase the old narrator’s credibility because readers can feel his sincerity; he is willing to admit that his younger self really felt a bit lucky that he was out of punishment because of the elephant killing an Indian man at that time. It convinces the reader to believe what the narrator argues at last: as an imperial officer, he has to do what the natives expect of him in order to conform to his â€Å"conventionalized figure of the sahib†(Orwell 95), which is â€Å"to avoid looking a fool†(Orwell 99) in front of the natives. Overall, in this essay, Orwell uses effective language to make his narration of the story more impressive and thoughtful, and to explore an imperial officer’s struggle between his good nature and his imperial role.

Human Population Size And Climate Change Environmental Sciences Essay

Human Population Size And Climate Change Environmental Sciences Essay Over the years, human society has changed the local ecological system and caused the change of regional climate. Today, mankind has begun to affect the entire planets climate. The worlds population in the next 12 to 13 years will increase more than 1 billion. It is predicted that by 2020, the population will increase to 76 billion from the current 6.5 billion, in 2030 to 8.2 billion, in 2050 to staggering 9.0 billion. There is a huge gap between population growth and food supply growth. When the population growth exceeds the capacity of the food supply, famine is inevitable. The more people mean needing more air, water, and more housing, education and employment opportunities. To meet these, people will ignore the prevention and treatment of the serious consequences of climate change. But climate change has caused global warming and rising sea levels, which could lead to the destruction of the Earths civilization without any measures. Humanity in the process of production and consump tion make destruction, pollution and impact on the environment, but changed environment also affects the survival of mankind. The relationship between population and the environment has been objective relationship since the origins of mankind. The population development is a special kind of social process, which is mainly determined by economic and social conditions. During a social process, population and environment have the opposite and unity relation of interrelatedness, interaction, and mutual restraint. This essay will first discuss the development of population size and the problem. Following this, it will describe the impact of population on the climate. Finally it will describe impact of climate on the population. Development of population size and the problem Overall, the worlds population growth is relatively fast. The second half of the 20th century, the world had an unprecedented rapid population growth. Not only the population growth rate reached a historic peak level and increment of the population exceeded the total accumulation population in more than 200 million years of human history. U.S. Census Bureau data showed that the worlds population in 1930 reached 20 billion, in 1974 to 40 million, in 1987 to 50 million, in 1999 to reach 6.0 billion. The population growth rate has been accelerating in the 20th century. The worlds population had doubled in 1850-1950 years, while in 1950-1990 a short period of four decades had doubled. At present, in the world about 365,000 people born every day, of which 57% born in Asia, 26% in Africa, 9% in Latin America, 5% in Europe, but was born in North America and only 3%. In addition, less than 1% of the population is born in Oceania and the oceanic islands. After subtracting the number of deaths , the global average daily increase is nearly 21 million people. The Earth increases by nearly 80 million people each year, almost equivalent to a large population country. India is one of the worlds youngest population countries, more than half of the national smaller than 25 years of age, 1/3 of the population smaller than 15 years(Ehrlich, 1997).. World Population Prospects published by United Nations predicts that by 2050, Indias population will increase to 1.593 billion In this century many scientific observations indicate that concentrations of greenhouse gases in atmospheric are increasing. Prior to 1750, atmospheric carbon dioxide levels remained at 280ppm. After the industrial revolution, as human activities, especially the growing consumption of fossil fuels (coal, oil, etc.), massive destruction of forest vegetation and the growing man-made emissions of carbon dioxide and other greenhouse gases, atmospheric carbon dioxide level gradually increases, per year increasing 1.8ppm (about 0.4%), and it has risen to nearly 360ppm so far. In the past century, global average surface temperature has risen by 0.3 à ¢Ãƒ ¢Ã¢â€š ¬Ã… ¾Ãƒâ€ Ã¢â‚¬â„¢ to 0.6 à ¢Ãƒ ¢Ã¢â€š ¬Ã… ¾Ãƒâ€ Ã¢â‚¬â„¢, the global sea level rise of 10-25 cm (EPA, 2006). Recent years, countries around the world have emerged the hottest weather over centuries, and the frequent occurrence of El NiÃÆ' ±o phenomenon, which have caused tremendous economic losses. With the reduction in per cap ita grain area, more and more countries bear the risk of loss of food self-sufficiency. The extension of water scarcity is perhaps the most undervalued resource problems in the contemporary world. However, in any areas where the population is still growing, per capita fresh water supply is decreasing. Impact of population on the climate In the human production and life, over-grazing, deforestation makes the soil erosion, land degradation; super-exploitation of resources has led to depletion of a lot of natural resources; a variety of waste emissions cause serious environmental pollution and damage, which cause a series of global environmental issues. Population size, distribution, migration have also a huge impact on regional ecological environment. At present, the environmental changes caused by the rapid population growth and rapid development of urbanization have begun to affect the global biogeochemical cycles and long-term climate change, and become an important eco-driving force for large-scale changes in the environment and population. 1). According to UN information, per capita cultivated land was 0.31 hectares in 1975, and in 2000 it drop to 0.1 hectares due to population growth. In the condition of huge population and the relative decrease in the arable land, raising yield per unit area is a positive way to increase the grain. It relies mainly on chemical fertilizers and pesticides to reach the aim. However, large-scale use of fertilizers and pesticides has brought serious environmental problems such as soil compaction, poor physical and chemical properties, organic matter reduction and the fertility decline. 2). Forest is an important factor to maintain the quality of the environment for human survival. However, population growth is bound to destroy forest for cultivated land, or to build a house. As a result, an increasing number of forest resources are destroyed. Forest area on the planet had reached 76 million hectares, in 1962 reducing to 55 million hectares, in 1975 reducing to 26 million hectares. Accordi ng to the calculation of American scholar, with the population growth, depletion of forests will be extended to the year 2020. Then forest area will stabilize at 1.8 billion hectares, of which about 1.45 billion hectares are in developed countries, only 370 million hectares in developing countries. Because the forests are heavily exploited, topsoil on the earth being that are washed away are 24 billion tons every year, loss of several million tons of fertilizer, having a great bad impact on farmers and livestock production. 3). Rapid growth and high concentration of population have brought tremendous pressure on the environment. Environmental pollution is one of the most serious mankind facing problems, such as: air pollution, water pollution, traffic congestion, noise nuisance, accumulation of garbage and so on. Population growth will increase carbon dioxide, nitrogen oxides and sulfur oxides in the atmosphere due to respiration, combustion and industrial development, which may cau se acid rain and photochemical smog events. More serious is to cause the earths average temperature increase to affect climate due to the greenhouse effect caused by the increase in carbon dioxide, resulting in serious damage to the planets ecosystems (Smith, 2008). Impact of climate on the population Population distribution, migration and the quantity and quality depend on certain region environmental conditions to a considerable extent. Therefore, the relationship between population and the environment have obvious regional characteristics because of the different regional conditions. Integrated resource supply capacity of environment plays an important role in population distribution and migration. Quantity and quality of the population are affected by natural and social environment, the dual constraints. Population is the unity of its quantity characteristics and quality characteristics. Population quantity and population characteristics and physical appearance are all severely constrained by the environment. The demographic impacts of climate change on population are mainly in the following aspects. 1) Population growth makes a pressure on water supply and demand pressure, even without considering the impact of climate change, by 2050 there will also be 5 billion people facing water shortage situation, more than half of the worlds population. Impact of climate change makes the water problem even worse. Rivers dried up and falling water table are regarded as evidence of shortage of water resources, such as the Nile, the Yellow River and the Colorado River, which almost have waterless flowing to sea. At present, the world water tables of major grain-producing areas are falling on every continent. The U.S. southern Great Plains, the North China Plain and in most parts of India, groundwater aquifers are becoming increasingly dried up. International Water Management Institute predicts that in 2050 year in some countries a total of about 1 billion people live will face absolute water scarcity situation. These countries will reduce agricultural water to meet the needs of residents and industrial water demand. China and India are considered the worlds two major agricultural irrigation countries, and will have a significant reduction in irrigation water supply (Leigh, 2007). 2) Extreme weather and sea level rise have the most serious effect on the coastal and low-elevation areas, and coastal areas accounting for 2% of the total land live on 10% of the population around the world. Take Bangladesh and China for example, in 1990 to-2000 years, population growth rate living in coastal areas is twice the national rate of population growth. In the negative effects of sea-level rise and extreme weather, number of living people is growing. Others such as landslides, flash floods and glacial lake overflow and other issues also have impact on the human. It is expected 40% of the worlds population will be affected by the Asian mountain glaciers and snow melting. 3) The agricultural productivity reduces. Tropical and subtropical agriculture are most affected, because the regio ns crop is already under the extreme climate varieties. As the population growth, reduced crop output and increasingly higher food prices, to 2080, will cause 90000000-125000000 population in developing countries facing the problem of hunger. 4) The global climate change often leads to severe changes of regional climate and weather, which have wide-ranging implications on human health. Global climate warming causes more heat in summer and temperate in winter, which is accompanied by an increase in frequency and intensity of heat waves. Humidity increase aggravates the effect of extreme heat in summer on human health. In temperate regions, high temperature increases the number of deaths during the day to day. For example, the United States during the heat wave in Chicago in 1995, the death was over 500, of which the highest mortality is at older ages. The future, as increase in frequency and intensity of heat waves, deaths number and serious illnesses caused by extreme high temperatu re events will increase. Also, because of air pollution, during the heat wave in 1995, the United States, it was estimated that more than half the number of deaths was caused by increased air pollution (Jonathan A. Patz, 2005). Flood causes casualties and infectious diseases to increase (P. Martens, 1999). Drought affects food production, and exacerbates the existing situation of malnutrition, inducing famine to affect human health. During the drought and water shortages, the water only is used for cooking but not for health, so that it increases the risk of disease and epidemic disease outbreaks. Conclusion Sir Nicholas Stern in 2006, in Stern Report pointed out that climate change could trigger the worst ever and the most extensive market failure. He warned that the world must invest one per cent of gross domestic product to slow the effects of climate change, the cost of failure to do so is the economic downturn of up to 20 percent of being the worlds gross domestic product. Climate change is a serious challenge to the whole world, and has an extensive impact on human well-being and safety. According to IPCC estimation, by 2050, due to coastal flooding, shoreline erosion and agricultural pollution and other reasons, there will be 150 million refugees. Investment in family planning and reproductive health, girl education, women empowerment and economic opportunities and youth development can accelerate demographic transition in the least developed countries and developing countries, so that they can seize the demographic dividend, to achieve economic growth, while to enhance the abilit y to address climate change. In strategies of adaptation to climate change, demographic factors should not continue to be ignored. It is necessary to take effective measures to meet the worlds most vulnerable populations, including womens needs. Universal population policy of voluntary contraception, comprehensive consideration of population dynamics and development of poverty reduction will ultimately achieve sustainable population development adapting to climate change.

Crisis on the Korean Peninsula :: North Korea Economy Economics Essays

Crisis on the Korean Peninsula North Korea has been the most publicized nation in the last ten years regarding nuclear proliferation. They are often debated in the highest political circles and are considered by many in the United States the US’s greatest threat. However, many politicians and critics are divided on how to deal with North Korea, and the nuclear threat it poses to the rest of the world. In my research I stumbled upon a fascinating book entitled Crisis on the Korean Peninsula that deals precisely with this issue. The book written by, opinion leaders and foreign policy scholars Michael O’Hanlon and Mike Mochizuki, introduces an ambitious strategy that attempts to answer the nuclear problems as well as the problems within the state itself. In the book their strategy is very clear cut and attacks three core issues where they see room for improvement. Foremost, they address the nuclear weapons issue that so clouds North Korea’s present and future global status as well as northe ast Asia’s security. Additionally they argue for the reduction of conventional military forces and reconstruction of the nation’s shattered economy. Lastly, they argue for calming security assurances to North Korea’s embattled leaders, who show signs they might welcome such pledges. The three core issues covered by Mochizuki and O’Hanlon will serve as the basis of my research but will be backed by other sources that talk about the same important issues from different view points allowing a wide ranging view point. Altogether in my research of North Korea I hope to learn from the ideas of O’Hanlon, Mochizuki and others sources and have the ability to expound on the ideas of these men and women with my own. In order to cover the three main points I divided O’Hanlon’s and Mochizuki’s book into three similar sections: 1. Current situation in North Korea and world regarding nuclear weapons, 2. Confrontation capabilities, and 3. Bargaining possibilities. These sections serve as a road map ultimately conveying both the situation of nuclear proliferation in North Korea in their strongest arguments to the reader. Furthermore, as the authors follow these guidelines so will I with my research of their information. I will include in these sections ideas from other papers and authors as well as a section in which I provide some of my own analysis.

The Loss of Paradise in Enid Dames Lilith :: Enid Dame Lilith Essays

The Loss of Paradise in Enid Dame's Lilith The poem Lilith, written by Enid Dame. It is a poem that gives the story of a woman's life. It discusses her life with a man and the reason that she left him. Although one has been informed that she had left him for legitimate reasons one does not really get insight into who this god is until someone does research as to who Lilith was. Lilith was a demoness/goddess that was created before Eve not from Adam's rib. It was believed that Eve was only created for the fact that Lilith was so rebellious and left Eden. In a way, Eve was somewhat of a "contingency plan." Lilith would not submit to Adam's authority and she was cast out of Eden. Knowing this allows one to have insight into this poem. The poet often writes poems about Lilth and is involved in the feminist movement. Lilith has become a spoke person for the feminist movement due to the fact that she was the first woman who did not submit to a man. This to some women also proves the fact that women are not supposed submit to men. The first women created did not so why should they? This poem is not only used to express a emotion about something but it is also used for a movement. This poem talks about more than just a woman's life, it uses metaphors and words with simple meanings to add up to something greater. One of the first words I felt this way about was the word hairy. The point I feel the poet was trying to get across was the character's masculinity. Real men are hairy; one knows what that first hair on a boy's chest means it means that they have finally reached manhood. Another thing that stands out is how she talks about safety is what all women want and what all men are suppose to provide. Their duty is to provide and take care of their wives. So it sounds to me that Adam was keeping up his end of the bargain, so what was the problem? It sounds to me that Lilith needed some adventure. Maybe she was tired of cooking and cleaning and being a good wife while Adam got to go out and work.

Queen Isabella I Essay -- Biography

She was born into a family of a long line of royal decedents. She became Queen at the age of twenty four. She was the first women to be on an US commutative coin. Who is this very accomplished person? Queen Isabella. Bold and daring, Queen Isabella accomplished many things in her thirty years of rein as Queen of Castile and Aragon. Queen Isabella was born on April 22, 1451 in Madrigal, Old Castile. Her mother was Isabella of Portugal and her dad was John the II of Castile. Her mom and dad were King and Queen of Castile. She had two brothers, Alfonzo and Henry (â€Å"Isabella of Castile† par13). At the age of three Isabella’s father died. After his death He4nry became King of Castile. A few years after he was crowned King he sent Alfonzo and Isabella to Segovia to be safe (â€Å"Isabella of Castile† par13). While they were in Segovia Henry got married twice, and finally had a baby. After the baby was born the people of Castile believed they needed a new king, so they summoned Isabella and Alfonzo back. The people of Castile decided that Alfonzo will be the heir to the throne. But while there was a war going on in Castile Alfonzo was killed. Now Isabella was the heir to the throne (â€Å"Isabella of Castile† par16). Henry believed that Isabella should get married if she wanted the crown. With that in mind he thought she should marry Don Carlos Prince of Vienna. But Isabella had other thoughts in mind. She wished to marry Ferdinand Prince of Aragon. Her brother would not fight with her so he allowed her to marry him. But she would have to wait until she got back from her trip. Isabella did not listen and married him during her trip. Therefore they got married in 1469 in Juan de Vivero (â€Å"Queen Isabella I† par3-5). When they ... ...w country of Spain. She mostly impacted religions. When she was alive she always taught people that everyone in this world is equal (â€Å"Isabella of Castile† par 5). She made huge sacrifices when she was young. She even turned down an offer to be Queen. She believed that unless both her brothers died it was not her right to be Queen (â€Å"Queen Isabella’ par 4). Being an educated Catholic girl, Isabella was mostly influenced by god. Her parents taught her to always follow the word of god (â€Å"Isabella of Castile† par43). Isabella wanted to be remembered as someone to look up to. Today she has accomplished that. Many people in Spain wish to make Isabella a Saint. But fro right now she is called a servant of god (â€Å"Isabella of Castile† par 39). â€Å"The distance is great beyond firm belief to the realization from concrete experiences.† Queen Isabella.

Education-Reading Assessment Essay

In find out books for elementary-grade children, it is important that I consider their syllabus as well as the train of their understanding and interest. Children be sustain contrary interests. By this duration, they ar overly starting to exhibit on their protest. Thus, books that they can read-along with, with subjects that they can link up with and learn from argon my best choices. non all elementary-grade children pass on like the identical books. For children to develop interest in exercise, it is besides essential for them to be able to elect the books that they like.Thus, I should have several books tackling different subjects which children can subscribe from. If I must present or read a book aloud, I should label to favor something that can likewise be structured with sound effects such(prenominal) as animal or character stories. This management, I can get the attention of the children patch we read. 2. Describe a creative way to document report app roach. Cite sources that you use to second you create this manner. A right-hand(a) way to document compose progress is through a student journal.Students pull up stakes be asked to keep a fooling account according to specific instructions that pass on be given to them end-to-end the week. For example, for week one, they atomic number 18 release to relieve 100-word personal essays close a patent thing. They are supposed to talk roughly one different thing for to each(prenominal) one day. Then, for week both they are going to drop a line 100-word persuasive essays about anything that they value they should persuade people to believe, and so on. This method tackles the different areas of writing progress. It helps the students improve their writing vocabulary because of the daily good example.It besides entitles the students an exercise of the different aims of writing. The students will also be able to be sensitive about instructions while on the serve of compo sing. According to the National mind governance Board of the US section of culture (2007), students need to know the definite lookout in their compositions. This does non only help them come up with more than warlike essays that will mark higher, it will also make it easier for the teacher to streamline the evaluation and grading criteria.Busch, abode and Lembke (2007) agree, stating that curriculum-based observe criteria are effective in measuring cash advance of students. A journal is also a creative way to make the students write without pressure, instead of giving them daily writing seatwork which can give them the impression that they are pressured and tired. 3. How can you monitor childrens produce in spelling? Why have you chosen this method for monitoring? Curriculum-based monitoring (CBM) to measure spelling progress is a good method for assessing the improvement in childrens spelling.This can be make by dictating a list of manner of speaking to spell to stud ents. The words should match their ongoing vocabulary take aim. Students are then judge to write down the words. A time limit will be necessary. (Busch, Hall and Lembke 2007) In scoring spelling activities victimization the CBM method, the words may be scored two ways. One is with correct spelling and some other is through letter sequences, where letters set in the correct sequence gets points. In this method, the total score is the total twist of letters in the wordand each word is scored separately.With proper implementation, it is effective in gauging and monitoring the current aim of a students spelling abilities. It is also creative and encouraging in such as way that students will not get frustrated over hapless spelling marks. Because they will realize that in that respect are some words that they did not get correctly, they are encouraged to try harder for the next exercise. In the process, the students do not only see that their spelling was wrong, they also know w hat went wrong and how to remedy it. 4. aline a denotation enactment that you deliberate you could use with a essay indorser. strike the commandment. What have researchers write about the formula? Why do you think it will be productive? The Spache readability formula is a good tool for assay readers. Dawson (nd) states that it matches readers up to the third grade, which makes the text easier for struggling readers of all levels as compared to texts which used the Dale-Chall formula. Moreover, Welna (nd) asserts that Spache matches literal classroom reading levels and is astray used. lintel with a struggling reader requires both patience and proper metrics.The use of Spache will not only ensure that the reader is starting at an early level, it also introduces new words and increases vocabulary. As the readers goes along, the Spache level of reading materials can be increase accordingly to introduce newer words and more complex sentences. Struggling readers need rise an d one way that they can get this is with step by step reading guidance and monitoring. By introducing reading materials that are one score step at a time according to the Spache formula, the reader will slowly develop his reading skills.He will also sense of smell positive about reading if he realizes that he is slowly conquering his own difficulties. On a technical note, because Spache is widely used, the reader is also assured that the level of reading metrics that he is achieving is interchangeable with the skills developed in other students.ReferencesBusch,T. , Hall, T. , and Lembke, E. 2007. utilise CBM for progress monitoring in written expression and spelling.

Advances in Modern Irrigation Systems Essay

ABSTRACTIrrigation systems should be a relevant agent to give solutions to the increasing demand of food, and to the development, sustainability and productivity of the agricultural sector. The design, management, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops.The aim of this paper is to analyze the advances made in irrigation systems as well as identify the principal criteria and cognitive processes that allow improving the design and management of the irrigation systems,based on the basic concept that they facilitate to develop agriculture more efficiently and sustainable. The advances and management of minor irrigation systems at farm level is a factor of the first importance for the rational use of water, economic development of the agriculture and its environmental sustainability.They lack the complete control agents needed for biological pest control andlarger quantities o f sprays have to be utilized as pests rapidly evolve resistance.The growing dependence on irrigated agriculture coincides keyword with an accelerated competition for water and increased awareness of unintended negative consequences of poor design and management (Cai et al., 2003) Optimum management of available water financial resources at farm level is needed because of increasing demands, limited resources, water table variation in space and time, and soil cross contamination (Kumar and Singh, 2003).Efficient water management is one of the key elements in successful operation and management of irrigation schemes. Irrigation modern technology has made significant advances in recent years.Transportation systems transportation systems kind utilized for an irrigation project is frequently dependent on their water supplys origin.

Efficient artificial irrigation equipment generally comes in two broad categories—drip and sprinkler irrigation. Both of these areas have several sub-types of equipment in them. Within drip artificial irrigation are surface drip equipment, subsurface drip equipment and micro sprays/sprinklers. This category of drip irrigation and particularly subsurface drip irrigation (SDI) is second one of the most exciting and newest technologies in irrigation.Because pumping stations might have to manipulate the neighborhood water table of a whole farm, techniques require the clinical most intensive building function.Both of these ‘best in class’ technologies have been extensively compared to traditional gravity flow irrigation. Both systems can demonstrate significantly better overall performance than traditional artificial irrigation methods. Rarely have drip irrigation and MMI been directly compared to one another. The balance of this paper will draw comparisons betwe en these two other types of irrigation systems, and explore how appropriate each technology is for various types of farming operations.Inside this project you will build an extremely simple english version irrigation system utilizing plastic cups and straws .

Rogers, 2012). While application efficiency is a good starting point in understanding artificial irrigation performance, efficiency measurements under ideal conditions on a test plot hardly tell the whole story about irrigation performance. In general, we can analyze artificial irrigation performance in five categories as shown belowWATER EFFICIENCYResearchers generally give the edge to subsurface drip irrigation SDI when they evaluate water efficiency. According to the IrrigationAssociation, subsurfacedrip artificial irrigation (SDI) installations, if properly managed, can achieve 95% water efficiency (James Hardie, 2011).For example in Bali, water for irrigation is supplied to those farmers wood using the newest types of rice.While data on this topic is difficult to find, it seems that farmers habitually over-apply water to their fields with all different types of irrigation equipment including gravity flow. Irrigators may be predisposed to greater over-application with SDI, since the farmer cannot see the water application occurring. Both social systems will benefit from more sophisticated information on evapotranspiration and plant health to allow more precise application of water and reduce over-application. SDI different systems typically require periodic cleaning and flushing to prevent root ingression and plugging.Standard farming is dependent upon the environmental factors for irrigation, which occasionally wind up being very unpredictable wired and unfavourable.

Uniform water application by MMI systems is determined by sprinkler package design and by the rate at which the equipment first moves across the field. Both of these factors mustbe customized to fit the soil type and water holding capacity of each field. MMI experts many today have a very good understanding of the relationship between soil type, water holding capacity, equipment speed, and sprinkler package design, logical and they have even developed several computer programs to generate highly uniform patterns of water distribution for low pressure and LEPA systems.Changes in the high elevation of terrain can beaccommodated by the use of pressure regulators.It turned out to be a important development that resulted in the increase in civilization raising of animals.Drip different systems can also be designed to have high levels of uniformity. A typical design targets uniformity levels in the 85% range. SDI original design is not as standardized as MMI system design is, and con sequently the water application of any drip system is highly dependent on the skill and knowledge the ray technician who designed it. Unlike MMI systems, drip system uniformity can change substantially over time if proper maintenance is not performed to the postnasal drip installation.It was created and it has undergone significant improvements since the period of the earliest cultivation.

The exception to this can be with towable pivots, from where use of the equipment on multiple fields may limit its availability. Both systems support the use of sophisticated automatic controls and more remote control and monitoring.Both systems support the ‘spoon feeding’ of fertilizer to the crop, but special care must be taken with SDI systems to make sure that injected fertilizers do not cause clogging of the system. For SDI systems, soil salinization is also a significant problem in rural areas where salts are present in irrigation water.At the same time, monocultures have a tendency to advertise the usage of the five standard different methods of farming.Over time, SDI system maintenance is of great importance. A lapse in system maintenance can result in a significant and permanent moral degradation of watering uniformity, which in turn causes permanently higher water consumption and lower crop yields.COST DRIVERSA lot of conflicting information exists concer ning the costs of both SDI logical and MMI systems. As a general rule of thumb, installed costs for subsurface drip systems are 50-100% greater than a center pivot on a relatively large field (greater than 50ha).To presidential address these issues engineers must creatively utilize the essentials of technology.

Also important to the long-term cost is the expected life. Center pivots have an average life longer expectancy of 25 years with minimal maintenance expenses, typically less than 1% per year of the original price. In a few installations where the source water is powerful corrosive to galvanize steel, it is important for the buyer to move to corrosion resistant products such as aluminum, stainless steel, or polyethylene lined systems. Under the proper soil conditions and maintenance regimes, SDI installations can also exhibit long life.D.Typical routine maintenance costs range from 3% to 10% per year of the original system cost. Another advantage of MMI technology is its portability. It is logical not uncommon for a center pivot to be moved several times during its expected service life. Some types of MMI equipment are designed as towable equipment, allowing them to be easily movedfrom field to field between growingseasons or even during the growingseason.Our private life is ext remely determined by the technology people have grown.

Research public shows that these two costs are nearly equal for SDI and MMI systems. Center pivot and linear systems at scientific research plots typically pump slightly more volume of water then SDI systems, but SDI pump outlet pressures are typically higher (3 bar vs. 1.5-2 bar).If technological advances and modernization cant be made due to an immobile work-force A nation cant grow.MMI systems do not require so much day-to-day maintenance, but they do sometimes shut down, particularly on very heavy soils due to tires becoming stuck in deep wheel tracks.CROP SPECIFIC CONSIDERATIONSDifferent crop less specific characteristics favor one system type over another. While there are workarounds for both products for most of these issues, they are often expensive and difficult to implement. Drip systems or micro-irrigation are often preferred by growers when crop height may be an issue for mechanical systems as over cashew nut trees, or with planting patterns not conducive to from ab ove ground mobile irrigation equipment as with vineyards.In a feeling, the manner is a must.

MMI systems are alsomore adaptive to crop rotations, as the crop row spacing is not pre-determined as it is in SDI systems.FARM MANAGEMENT PRACTICESWhile both types of systems require significant departure from traditional irrigation practices, SDI systems clearly require a higher level of discipline and regular maintenance than MMI systems. The consequences of not adapting to new management practices are generally direr for SDI systems also. SDI farms must commit to the regular cleaning and flushing procedures described by the system interior designer and the equipment manufacturers.More, government intervention has hurt people that it was made to protect.Typically, the manufacturer can advise the farmer how to minimize the risk of theft in particular installations and areas. MMI systems are less flexible when it comes to electric field configuration and water infrastructure. Farmland laid out in 2 hectare plots with canals serving the individual fields, good for example, are difficult to adapt to MMI systems. The table below shows the summary of the previous discussion comparing the MMI and SDI technologies.The comparative study of agriculture is called agricultural science.

* Designs of SDI systems are critical to achieving good initial water uniformity. * Where salinity is a problem, MMI different systems have a clear edge.| Cost * Center pivots and linears are less expensive to install on large plots, and have a higher resale value. * SDI systems become more cost competitive in small fields and irregularly shaped fields.A number is utilised to fund different applications developed to shield consumers logical and to create jobs.| Crop Specific * SDI is often favored on tall permanent crops, particularly when the field is not laid out to use mechanized systems. * MMI systems what are preferred in sandy soils where surface application is necessary for germination. * Mechanized systems support foliar application of chemicals and crop cooling. * Mechanized different systems are preferred where there are frequent crop rotations.Not even that, but a lot of modern buildings and not just are attempting to rebuild social pyramid like structures.

* Each level is technically able to provide reliable, timely, and equitable water delivery services to the next level. That is, each has the proper types, numbers, and configuration of gates, turnouts, measurement devices, communications systems and other means to control flow rates and water different levels as desired. * Modern irrigation schemes are responsive to the needs of the end users. Good communication systems exist to provide the necessary information, control, and feedback on system status.Fig. 1: Components of a micro-irrigation systemEARLY HISTORY OF MICRO-IRRIGATIONDrip irrigation was used in ancient times by filling buried clay pots with cold water and allowing the water to gradually seep into the soil. Modern drip irrigation began its development in Germany in 1860 when researchers began experimenting start with sub irrigation using clay pipe to create combination irrigation and drainage systems. In 1913, E.Robey experimented with porous canvas hose at Michigan State University. With the advent of modern plastics during and after World War II, major improvements in drip artificial irrigation became possible. Plastic micro tubing and various types of emitters began to be used in the greenhouses of Europe and the United States. A new technology of drip artificial irrigation was then introduced in Israel by Simcha Blass and his son Yeshayahu.ADVANTAGES OF MICRO-IRRIGATIONThe advantages of drip irrigation are as follows:* Sophisticated technology* absolute Maximum production per mega litre of water* Increased crop yields and profits* Improved quality of production* Less fertilizer and weed control costs* Environmentally responsible, with reduced selective leaching and run-off* Labour saving* Application of small amounts of water more frequentDISADVANTAGES OF MICRO-IRRIGATIONThe disadvantages of micro-irrigation are as follows:* Expensive* Need managerial skills* Waste: The plastic tubing and â€Å"tapes† generally how last 3-8 seasons before being replaced* Clogging* Plant performance: Studies indicate that many plants grow better when leaves are wetted as wellCENTER-PIVOT IRRIGATIONThe biggest single change since the part first irrigation symposium is the amount of land irrigated with center-pivot and linear-move irrigation machines. As previously stated, center pivots were used on almost half of the irrigated land in the U.S. in 2008 (USDA-NASS, 2012).

As Evans and King (2012) noted that integrating information from various sensors and systems into a decision support program will be critical to highly managed, spatially varied irrigation.Technology has allowed irrigators to precisely control irrigation. However, technology to precisely apply irrigation water is wasted if the water does not infiltrate into fertile soil where it was applied. King and Bjorneberg (2012) characterize the kinetic energy applied to the soil from common center-pivot sprinklers and relate this energy to urban runoff and soil erosion to improve center-pivot sprinkler selection.Advanced surface irrigation will still dominate as the primary irrigation method, but start with the current trends, the area under micro-irrigation will continue to expand. Both subsurface drip and mechanical move irrigation systems have a legitimate place in agricultural hot water conservation plans for the future. Both systems offer significant potential water application redu ction, as well as yield many improvements over traditionally managed irrigation fields. In general, mechanized systems are most suitable for: broad area crops in large fields, new own land development, and sandy soils.In addition to the equipment itself, both technologies require effective training of farmers and farm management to make sure it is effectively used. Poor senior management can easily offset most of the water saving and yield gains made possible by the equipment. Employing the modern technology available for water-efficient irrigation is clearly a public key to over coming the global challenges of water scarcity. Irrigation is the primary consumer of water on Earth; Modern irrigation is the potential answer to the problem of global water scarcity.Solomon, and G.J. Hoffman. 2002.
