Reflection Paper - 948 Words

For most people, they learn how to improve their reading and writing skills in Elementary School easily. I am one of the few that had to put more effort to improve our reading and writing. Some also may say that one event was the only event that affected their writing styles to make them to what they are now. I believe it takes more than one event to define how we behave, write, or interact. It takes multiple events to help shape how we write, such as, having extra help from the school, having a teacher sit down and talk with you, or having parents put more effort towards you practicing. I came from a Spanish speaking household and I still do to this day. Having my first language as Spanish and not English caused me to learn English later†¦show more content†¦I felt relieved and did not worry as much because I thought it was a simple warning and it would not be bad. Then she told me I could fail, that is when my worries came back but more intense. I stopped hearing everything she was saying as my mind started to drift off thinking about my parents giving me a spanking, taking my games away, grounding me, and all the other punishments they could possibly give me. It became even worse when she told me that she is going to send the grades home and that I need to have my parents sign it. When I got home I was extremely nervous to show my mom the grades. When I finally got the courage to tell her she got upset and started yelling things that I should not repeat here. After she got done yelling I promised I would try to get good grades and not be lazy so that I do not get behind. My mom decided that she will have to force me to read and practice writing because I am a lazy person. Because she knows I am lazy, she does not believe I will study and practice to bring my grades up. Every day while she was cooking she would sit me at our kitchen table and would have me read out loud for her. The book I read did not matter to her if I read a book at my grade level or higher. I do not enjoy reading books for fun so I did not have any in my room for me to choose from. My older sister is a big book nerd and enjoys reading lots of books for her free time.

Racial Disparities Between White And Black Americans

Over the past couple of months Obama has talked about how he wants to take on criminal justice reform. Recently both political parties have shown bipartisan support for reforming the criminal justice system. Senator Chuck Grassley has introduced a sentencing reform bill that appears to have bipartisan support. [1] Some liberals say this bill will help to address racial disparities; however, although this is a step in the right direction this bill, if it were to become law, would not significantly change the racial disparities between white and black Americans. The bill fails to address the stigma felons face in the job market, it fails to address a felons right to vote, and it fails to address crime prevention. To fully address racial disparities in American nearly every institution will require some form of reformation. In the labour market blacks continually face discrimination when looking for a job. Even when black Americans have a degree they often find it even harder to receive a job offer [2]. To find a high paying white collar job blacks often adjust their resumes to appear â€Å"white†. [3] The challenge of finding a job increases dramatically when jail time has been served. One study found that blacks are much less likely to find a job if they have been convicted of a felony.

Importance of Staffing Function Free-Samples Myassignmenthelp.com

Question: Discuss about Importance of Staffing Function to Organization. Answer: Introduction Staffing function is very important for each and every organization whether profit-making or not. Every organization that has employees must have the staffing function which is usually under the human resource department. Staffing can be defined as a function of management which involves recruiting, hiring, promoting, demoting and deciding salaries and wages as well as supervision of an organization's workforce. There is a lot of literature that has been written concerning staffing in organizations. Different writers have different perspectives on staffing in organizations with some viewing it as part of an organization's strategy and other writers viewing staffing as a traditional role of hiring and firing. This report analyzes the past literature that has been written on the above-mentioned subject to identify similarities and differences in views and ideas of different researchers. This will help in identifying the existing gap in research on staffing in organizations. Further res earch on the subject can be done after gaps have been identified in order to fill these gaps Literature review Staffing is a function in the human resource department and it is a process and therefore involves several procedures or aspects. Some of the aspects of staffing include; determining workforce requirement, recruitment, selection of candidates, orientation and placement of new staff, training and development, appraisal of performance, promotion of employees, compensation and the role of terminating employment through retirement or sacking. This report discusses and analyzes the views and ideas of different researchers on each and every staffing role in order to compare and contrast so as to identify the gaps in research. (Arthur,2012) and (Scott Reynolds, 2010) argue that the process of identifying the staffing requirement or need is the most important stage in the staffing function.(Scott Reynolds, 2010) argues that need identification in staffing is important because, it helps an organization to identify gaps in human resource and therefore, if the gap is not identified correctly, the rest of the process will be unsuccessful. He articulates that the stage of identifying human resource needs involves determining the positions that need to be filled and the job qualification. He, therefore, concludes that the need identification is the backbone of staffing since it determines the output and hence determines whether or not an organization will achieve its staffing objectives. (Arthur,2012 )also argues that wrong assessment of staffing needs for an organization may result in the creation of unnecessary positions and hiring of extra staff who may not add to productivity hence having negative consequen ces on the organization. According to (Griffin Moorhead, 2012), the role of recruitment in an organization is very complex and sometimes most organization may not possess the capability to recruit the best candidates available for the job. He argues that it is important for organizations to outsource the recruitment role. (Griffin Moorhead, 2012), argue that outsourcing of recruitment to a professional human resource management firm has many advantages as compared to doing the function from within. One of the advantages of outsourcing recruitment of staff is that it helps an organization to reduce the cost involved in recruitment. Outsourcing also ensures that the best candidates are selected since the function is carried out by an organization which has specialized in the sector and therefore has more knowledge of the market and more resources to perform the role than other organizations. (Heneman, Judge Kammeyer 2015) also, supports the idea of outsourcing in the recruitment of staff for an organization . The main reasons why organizations should outsource according to (Heneman, Judge Kammeyer 2015)s so as to cut costs and to enable the organization to focus on its main functions.(Bak Stair, 2011)however, goes contrary to the idea or practice of outsourcing the recruitment role. According to (Bak Stair, 2011), organizations are more suited at recruiting the most qualified staff by themselves since they have a better understanding of their staffing needs and therefore know exactly where to recruit and the type of people to recruit. Therefore, organizations should analyze and identify the suitable sources of their desired human resource and invite applications from willing candidates. Selection of staff or candidates after applications have been made is also a very crucial role of staffing. (Bak Stair, 2011)argues that selection of employees should be done in a very systematic manner and the organization should use a combination of various attributes methods to select the most suitable candidates for the available posts. This is due to the various factors that influence the performance of an individual in an organization and therefore it is important to select employees using a criterion which is unbiased and very objective.(Griffin Moorhead, 2012) also supports this view by arguing that most organizations tend to focus on academic qualifications and their level of experience of an individual candidate, something that does not really measure the forecast productivity of that individual. He argues that some organizations also tend to select staff who are related to powerful people working in the organization, something that is not only unethical but also unprofess ional. Therefore, it is important for organizations to be very thorough in selection since selecting the wrong candidate can be very costly for the organization both directly and indirectly. Training is another aspect of staffing that many researchers have written about. Training involves equipping employees with the right knowledge and skills that are required to perform their roles and responsibilities more effectively. Different writers have different opinions on the importance of training to an organization.(Griffin, Phillips Gully,2017) argues that training is a very crucial aspect in human resource management since it helps in increasing efficiency in an organization. He discusses that all organizations should have concrete training programs that are well funded in order to ensure that the workforce is updated especially during this era of technological revolution. (Nuhn, 2014) differs with (Griffin, Phillips Gully, 2017)arguments. (Nuhn, 2014) articulates that training is very expensive for organizations and they result in extra expenses for an organization. Therefore, organizations should recruit staff who are well trained and experienced in order to do away with training expenses. He argues that employees do not need to be necessarily trained in order to have developed new skills because they can develop them through personal effort. (Caruth Pane, 2009) argues that training is fundamental for every organization since it helps to equip workers with skills needed to operate new machinery and also teaches them workplace safety. This helps in improving productivity and reducing work-related injuries. Performance involves assessing the performance of employees and comparing it with their income in order to find ways of improving performance. Performance appraisal may also involve job appraisal. A lot has been written about performance appraisal in organizations. (Niehaus Price, 2015), discusses that organizations need to come up with concrete and measurable indicators that will be used to measure the performance of employees. He argues that in order for an organization to measure performance they must develop tools to measure performance such as benchmarking. Organizations should set goals for each and every employee. After the end of a particular period, this performance of the employee is compared to the set objectives. In case the goals have not been achieved, an assessment is done and corrective action should be taken. (Younger Smallwood, 2016) also, argues that performance appraisal helps organizations to determine the productivity of an employee which eventually determines the overall performance of the organization. In his research, he found out that 91% of organizations whose individual employees often fail to meet their individual targets also fail to achieve their overall objectives. He, therefore, concludes that organizations should set reasonable performance expectations and use measurement methods that are reliable, accurate and efficient in terms of cost to the organization. After the performance of individuals has been measured, the process that follows involves rewarding those who performed well and taking measures to improve the performance of those who failed. One of the ways in which good performance is rewarded is through promotion. From the findings of research by (Sisney,2012), out of the 500 employees interviewed in his research, more than 86% of the respondents indicated that their main motivation for work Is promotion. Therefore employee promotion is a very important tool for motivation. Therefore, organizations should put in place a system that prioritizes internal recruitment for top jobs in an organization so as to motivate employees to work harder. (Scott Reynolds, 2010) also agrees with (Sisney,2012) He argues that organizations should consider promotion as being an important motivator. He says that organizations should, therefore, put in place a promotion policy in order to ensure that promotion in an organization occurs purely on the ba sis of performance and favoritism does not occur. Abuse of promotion by the management can have very negative impact on the organization in terms of workers productivity and morale. According to Scott Reynolds (2010) compensation scheme or policy of an organization is also very crucial and therefore an organization should come up with a policy that compensates employees fairly. This should be done by conducting job evaluation before deciding on salaries and wages of individuals working at various levels within the organization. Conclusion Staffing is a very complex role of human resource management and it is very crucial to the performance of an organization. Many researchers emphasize the importance of need identification stage in the staffing function. Outsourcing of the staffing function is also becoming popular with many organizations preferring to concentrate on their core business and reduce costs. Various methods used in performance appraisal like benchmarking and scaling should be measurable and reliable so as to attain accurate results on the performance of employees. The role of promotion and compensation in the motivation of employees is very huge. The gap identified in this literature is the how training and employee development benefits an organization.

Morries Aphorisms Essays - Educational Psychology,

Morrie's Aphorisms No bubble is so iridescent or floats longer than that blown by the successful teacher. Sir William Osler (1849-1919), 4 Oct. 1911, Glasgow (quoted in: Harvey Cushing, Life of Sir William Osler, vol. 2, ch. 31, 1925). Mitch Albom wrote Tuesday's with Morrie as a final tribute to his old college professor, Morrie Schwartz, who intended that his death should be his "final thesis." Grim and fascinating, Professor Schwartz's courage in the face of a painful death is truly inspiring. The lucidity and wisdom which Professor Schwartz gained over the years became increasingly pronounced and focused as he contemplated his life and imminent death, as well as his place in the Cosmos while his frail body melted away through A.L.S. (Lou Gehrig's disease). This paper will discuss five of Professor Schwartz aphorisms (or proverbs), which would facilitate learning in subject- specific -and other educational venues. The Meaning of Life "So many people walk around with a meaningless life. They seem half-asleep, even when they're busy doing things they think are important. This is because they're chasing the wrong things. The way you get meaning into your life is devote yourself to loving others, devote yourself to your community around you, and devote yourself to creating something that gives you purpose and meaning." (emphasis added) (p. 43) Professor Schwartz's analysis of the "meaning of life" is particularly appropriate for teaching philosophical views and sociological concepts. Since time immemorial, man has contemplated why he is on the Earth and what his place is in the ?Greater Scheme of Things'. While students rush through the educational process in a pinball-like attempt to learn what they need to thrive and survive, they frequently overlook those aspects of their education, which are the most important. When people become self-actualized, as Professor Schwartz did, they are better able to view humanity from a broader angle. This "better view" of mankind involves a commitment to others and to the community in which one lives, but it is more elemental than that. Material possessions, according to the professor, mean little when you are lying on your deathbed. What is truly important is that an individual's life is given meaning and purpose by the degree to which that individual has served and loved others. Admittedly, Professor Schwartz had the wisdom of years and the insight provided by decades of philosophical research; however, the quest for the "meaning of life" is a universal aspect of mankind and finding the right answer is like finding the Holy Grail -- many have looked but few have seen. Therefore, Professor Schwartz's thought process concerning devoting oneself to loving others and their community is particularly appropriate in a philosophical and sociological learning environment. A better learning experience could be gained by a requirement that all college students perform a certain number of hours of service to the community: painting and repairing low-income housing, or volunteering at nursing homes or veteran centers, for example. This "giving back" to the community would reinforce Professor Schwartz's view that we are all part of the human family and we gain meaning in our lives through service to others. An activity using this aphorism in the classroom was completed by my sixth grade Literature class at Greenwich Catholic School. The grade decided to express the ?true meaning' of Christmas by bypassing the holiday gift giving and donating their gifts to a local charity of the children's choice. Then, each child wrote an essay on the ?true meaning' of Christmas and related their experience to the activity performed. This truly put Morrie's proverb to work. Faith and Trust "You see," he says to the girl, "you closed your eyes. That was the difference. Sometimes you cannot believe what you see; you have to believe what you feel. And if you are ever going to have other people trust you, you must feel that you can trust them, too -- even when you're in the dark. Even when you're falling." (p. 61) There is an old saying concerning trust and faith: "Fake it till you make it." This means that trust and faith can be learned. Trusting others is more difficult for some people than others. Trust, then, is the basis for all human endeavors, which involve others, since we must accept on faith that people will act in certain ways in order to live our daily lives. For example, in a learning environment, trust is the basis for the effective transmission of knowledge from teacher to student. Moreover, it is the essence of living in a civilized society, for, if we

10 Argon Facts - Ar or Atomic Number 18

10 Argon Facts - Ar or Atomic Number 18 Argon is atomic number 18 on the periodic table, with the element symbol Ar. Here is a collection of useful and interesting argon element facts. 10 Argon Facts Argon is a colorless, flavorless, odorless noble gas. Unlike some other gases, it remains colorless even in liquid and solid form. It is nonflammable and nontoxic. However, since argon is 38% more dense than air, it present an asphyxiation risk because it can displace oxygenated air in enclosed spaces.The element symbol for argon used to be A. In 1957, the International Union of Pure and Applied Chemistry (IUPAC) changed argons symbol to Ar and mendeleviums symbol from Mv to Md.Argon was the first discovered noble gas. Henry Cavendish had suspected the elements existence in 1785 from his examination of samples of air.  Independent research by H.F. Newall and W.N. Hartley in 1882 revealed a spectral line that could not be assigned to any known element.  The element was isolated and officially discovered in air by Lord Rayleigh and William Ramsay in 1894. Rayleigh and Ramsay removed the nitrogen, oxygen, water, and carbon dioxide and examined the remaining gas. Although other eleme nts were present in the residue of air, they accounted for very little of the total mass of the sample. The element name argon comes from the Greek word argos, which means inactive. This refers to the elements resistance to forming chemical bonds.Argon is considered to be chemically inert at room temperature and pressure.Most of the argon on Earth comes from the radioactive decay of potassium-40 into argon-40. Over 99% of the argon on earth consists of the isotope Ar-40.The most abundant isotope of argon in the universe is argon-36, which is made when stars with a mass about 11 times greater than the Sun are in their silicon-burning phase. In this phase, an alpha particle (helium nucleus) is added to a silicon-32 nucleus to make sulfur-34, which adds an alpha particle to become argon-36. Some of the argon-36 adds an alpha particle to become calcium-40. In the universe, argon is quite rare.Argon is the most abundant noble gas. It accounts for about 0.94% of the Earths atmosphere and about 1.6% of the Martian atmosphere. The thin atmosphere of the planet Mercury is about 70% argon.  No t counting water vapor, argon is the third most abundant gas in the Earths atmosphere, after nitrogen and oxygen. It is produced from fractional distillation of liquid air. In all cases, the most abundant isotope of argon on the planets is Ar-40. Argon has many uses. Its found in laser, plasma balls, light bulbs, rocket propellant, and glow tubes. Its used as a protective gas for welding, storing sensitive chemicals, and protecting materials. Sometimes pressurized argon is used as a propellant in aerosol cans. Argon-39 radioisotope dating is used to date the age of ground water and ice core samples. Liquid argon is used in cryosurgery, to destroy cancerous tissue. Argon plasma beams and laser beams are also used in medicine. Argon may be used to make a breathing mix called Argox to help remove dissolved nitrogen from the blood during decompression, as from deep-sea diving. Liquid argon is used in scientific experiments, including neutrino experiments and dark matter searches. Although argon is an abundant element, it has no known biological functions.Argon emits a blue-violet glow when it is excited. Argon lasers exhibit a characteristic blue-green glow.Because noble gas atoms have a complete valence electron shell, they are not very reactive. Argon does not readily form compounds. No stable compounds are known at room temperature and pressure, although argon fluorohydride (HArF) has been observed at temperatures below 17K. Argon forms clathrates with water. Ions, such as ArH, and complexes in the excited state, such as ArF, have been seen. Scientists predict stable argon compounds should exist, although they have not yet been synthesized. Argon Atomic Data Name Argon Symbol Ar Atomic Number 18 Atomic Mass 39.948 Melting Point 83.81 K (189.34 C, 308.81 F) Boiling Point 87.302 K (185.848 C, 302.526 F) Density 1.784 grams per cubic centimeter Phase gas Element Group noble gas, group 18 Element Period 3 Oxidation Number 0 Approximate Cost 50 cents for 100 grams Electron Configuration 1s22s22p63s23p6 Crystal Structure face-entered cubic (fcc) Phase at STP gas Oxidation State 0 Electronegativity no value on the Pauling scale Bonus Argon Joke Why dont I tell chemistry jokes?

Yet, his fame is due not only to these achievements but also to his remarkable ability to communicate his views and ideas effectively. A self-taught writer, Franklin immortalized himself with his book on electricity, his world-famous Autobiography and his role in drafting the Declaration of Independence. While Benjamin Franklin's contributions to many areas of American and international life, including science, politics, and social reform, are in themselves extraordinary; his writings are the key to his widespread and lasting influence. A large part of Benjamin Franklin's reputation rests upon his scientific writings. Eighteenth-century science was not divided into different specialized fields such as physics, geology, biology, and chemistry. Instead, there was only one broad area of study known as natural philosophy. Franklin, a brilliant natural philosopher, wrote about a wide range of scientific subjects, from meteorology to hypnotism. His studies gave scientific credibility to the field of electrostatics (the study of electric charges), influencing renowned scientists such as Count Alessandro Volta and Henry Cavendish and setting the course for all future development in the field (Crane 52). Within Franklin's studies, even individual words have been of great significance. For example, Franklin invented a number of electrical terms, such as "positive charge' and "negative charge," which are still used today. Franklin achieved even greater fame as a scientist through his personal correspondence with scientists across North American and Europe.

Brazil, Russia, India and China (BRIC) are seen as the key new players Essay - 1

Brazil, Russia, India and China (BRIC) are seen as the key new players in the global economy - Essay Example The economic potential of BRIC countries is such that they could exceed the combined economies of the richest countries and become among the four most dominant countries in the world by 2050. The combined GDP of the BRIC countries of 18,486 trillion dollars make them the fastest growing emerging markets in the world (Murray, 2006). Among the BRIC countries China proved to be the most dominant and progressing, which is considered by others either as a threat or an opportunity. The current paper will briefly discuss the influence of BRIC countries on the global economic development with special emphasis on China as one of the largest and most promising markets (Rao, 1998). Despite the BRIC countries are not a political alliance as the European Union or formal trading association as ASEAN, their cooperation and combined actions are directed toward improving the political cooperation to confront the increasing influence of the United States in the major trade accords. It is expected that in the near future Brazil and Russia will become the dominant suppliers of raw materials for India and China that in their turn will become the dominant suppliers of manufactured goods and services (Goodman, 2005). In such a way, these four countries shown below might form the ideal combination of suppliers and manufacturers to provide the rest of the world with necessary goods and services. Table 1 in the Appendix shows the comparison between BRIC countries and G7 countries in terms of GDP. While in 2015 BRIC countries will have much less combined GDP of 13,653 US$ billions than G7 countries (GDP of 33,414 US$ billions), then by 2050 BRIC countries will be twice more p owerful in economic terms expecting 128,324 US$ billions in comparison to G7 GDP of 66,039 US$ billions. By entering the world economy and introducing changes and innovations in such fields as education, foreign investments, domestic
