Myers-Briggs Paper

Mallory Simpson Psych 101: Myers-Briggs Paper Professor Baker 8/13/12 After taking the Myers-Briggs test, I am not at all surprised by the results I was given. 67% introvert is what I was distinctively ranked for personality type and I couldn’t agree more. Next on the list was 44% judging. This particular one leaves me wondering what type of judging? Is it being a judgmental person, or rather judging between the pros and cons of something, or maybe judging based on intuition or discernment. I think that a lot of people that know me would agree with this aspect also. 8% was the score for feeling. Although I agree with the order of the results, I would also put feeling number one. I am most definitely a feeling person. I would assume that this goes along with emotions also. Not only am I worried about how I may feel about a particular situation, I often wonder how the other person may feel as well. Lastly on the list I scored a 25% for sensing. When I think about the difference between an introvert and an extrovert, I think the biggest difference is the ability to sit back, relax, and see the bigger picture.A lot of introverts are quiet and observant and able to see things that an outgoing, always on the go, loud and talkative extrovert may miss. Of course, this may not be the case for every opposite, but I think for the majority it is true. An extrovert has the advantage to get out and seize the opportunity that an introvert may miss which is the biggest positive I see for an extrovert. The Myers-Briggs test was very insightful for me. â€Å"The wise of heart will receive commandments, but a babbling fool will come to ruin. † –Proverbs 10:8

Shawshank Redemption

Andy’s Changed Life In the film, Shawshank Redemption, directed by Frank Darabont, insight was given to the life of prisoners in bondage. Tim Robbins’ character Andy gave an excellent illustration on how new prisoners enter a world of unknown dangers and survive. Andy’s metamorphosis from â€Å"lanky new fish† to a man of prestige was definitely interesting. His change reflected on his fellow prisoners, the Prison staff, and himself as well during his sentence. Andy exemplified a man who could compromise with his surroundings and make the best of every moment.The story of Andy’s life in the Shawshank Redemption gave insight for every man beginning his prison journey. Upon the arrival of all new prisoners stood Andy, a man convicted of murder. Like any other, bets were placed on him to challenge how long he could last. Andy began his new life quiet and concrete. His fellow prisoners had no idea what type of man he would become. After being attacked a nd raped on numerous occasions Andy had to stand up for himself. As he gradually made friends with Morgan Freeman’s character, Redd, his network grew. He needed things and Redd got it for him.From that point on because of his attitude people grew interested. Andy became one of the most friendliest and dependable friends any of the prisoners ever had. The ways he carried himself and acted upon situations were accepted throughout the entire prison. Once he became well-known it was as if he was the leader of a new clan and the people enjoyed following him. He opened pathways for the men and fought for their education. Through him the prisoners were able to enjoy a library and earned opportunities to get their GED or anything else. Andy was definitely no longer a â€Å"lanky new fish† by the time he left Shawshank Prison.As for the Prison staff at Shawshank Prison, Andy’s attitude and persona took a toll on them as well. Andy was never one to cause trouble or engage in anything involving violence. After a bold act towards the head officer Andy became the accountant and tax preparer for almost the whole Prison Staff. He helped to set up college funds and savings for many of the officers. Andy’s work became so good that the warden himself used him as his personal accountant to maintain his dirty money. At this point Andy had gained respect throughout the entire prison and the officers often looked out for him.The Prison staff became dependable on Andy and his marvelous works. He handled and managed their money so they really had no choice but to trust him. I think it shocked every officer to see himself getting help from a prisoner. As Andy grew within the prison, it can be assumed that he became a prominent figure in maintain the prison itself. Therefore his role as a prisoner seemed to have disappeared and he was just a man. Officers may have feared him as a person because he grew with prestige but in the end they needed him. Every man can see a change in himself whether it is good or bad.Andy definitely saw his change from when he first entered to his last days standing on in the prison yard. When he entered prison he had no idea what he had actually done. After sitting around and living from day to day he was able to realize that life is entirely too short to sit and do nothing. He had been sentence to life on behalf of each murdered person and it was nothing he could to about. He compromised, made friends, and made the best out of every moment. He grew to recite his favorite line, â€Å"I’m innocent, isn’t everybody here? Andy noticed the life of others and knew that it wasn’t a life for him. People depended on the four walls that surrounded them, but Andy understood that they were only temporary. There was life beyond what Shawshank Prison offered. As he looked in the mirror and saw how he was aging his whole attitude changed and it reflected on in his walk and even his talk. Life is all about changing and living. Andy’s life definitely changed and he lived through each moment. His fellow prisoners had first hand experience of his life as an innocent man to a man who could and would take risk.As it shocked them, it shocked him as well. The Prison Staff didn’t clearly understand the type of man he was because he was one of a kind. I admire him because he took his surroundings and made life of it. He helped and changed people’s mind sets of life itself. Andy opened people’s hearts and minds and did it all out of his heart. I don’t believe that he needed prison to understand his purpose in life but it definitely helped him to find one. Works Cited Shawshank Redemption. Dir. Frank Darabont. Columbia Pictures, 1994.

Human Resources- Relationships in the workplace Research Paper

Human Resources- Relationships in the workplace - Research Paper Example Companies have been attempting to establish clear, well-understood policies to minimize the potential for danger – both for the employees and the organization. However the role of the HR in an organization remains controversial as far as dealing with workplace dating and relationships is concerned. Gautier has explored the reasons for workplace romance and found that theories of attraction play a vital role. Social psychology also points out a strong link between proximity, familiarity and attraction. Because of close and frequent interpersonal interaction they are prone to develop relationships. People with similar beliefs, attitudes, education and background are also more likely to be attracted to each other. They have similar traits and goals; share each other’s excitement and frustrations, and celebrations (Loftus, 1995). At the same time, organizational attitude, culture and beliefs play a role in how the companies conceptualize, tolerate and manage workplace romance. The role of HR in workplace relationships is debatable. When Wal-Mart terminated the services of two of its workers who were dating, it was found that the supervisor used an out-of-date policy manual to justify their termination (Losey, 1993). A survey revealed that more than 70 percent organizations permit and accept workplace dating as most were of the opinion that the organization has no right to interfere in the dating between coworkers (Losey, 1993). However, when dating involves an employee dating a boss, or the upper management or the manager dating a subordinate, it has been found to be unacceptable (Gautier, 2007). Only if a supervisor dates a subordinate, can the organizations interfere and this has become important because of some well-known sexual harassment court battles (Jenner, 1993). There have been instances when an employee had voluntary--but not

Gross Domestic Production Essay Example | Topics and Well Written Essays - 1500 words

Gross Domestic Production - Essay Example From the above equation employee compensation, operating surplus and mixed income added together are referred to as factor income. It is therefore evident that this method involves adding up income earned by factors of production. This is another method used in calculating GDP and the method involves adding up the unit rise in prices of products in the production stages. Therefore this method involves adding up contributions of the factors of production that add value to a product. Value is added either through services rendered and goods used to process final products. However calculation of GDP using the above three methods should be the same, the expenditure method is commonly used in many countries to calculate GDP due to the availability of data, the following is an analysis of changes in GDP due to increase in production and change in price. The following information on the production of a good is provided, Lenovo produces 10,000 units of a product with a market value of 2,000 each in 2009 December; however no units are sold until spring of 2010. The following are the requirements: For this reason therefore the Lenovo products produced and not sold in this year will increase the level of investment in terms of an increase in inventory, the following is a summary of the calculations: Given that 10,000 units were produced and the market price of these products is 2,000 then it is possible to determine the GDP level increase as a result of this production, the value of these products is determined by multiplying the quantity produced and the prevailing market price, and the following formula is used: Value of products = quantity X price (Obstfeld (1997)) Substituting the values as follows: 10,000 X 2,000 = 20,000,000 dollars From the above calculation therefore it is evident that the GDP level in 2009 will increase by 20,000,000 dollars, this increase will be as a result of the increase in investment in the year 2009. b) GDP increase in 2010: The GDP level will be affected in 2010; there will be an increase in consumption in this year

GREECE Essay Example | Topics and Well Written Essays - 750 words

GREECE - Essay Example Beautiful nature, geographical position and warm climate make Greece attractive for immigrants. â€Å"Greece's geography, which became especially important after the formation of Europe's borderless Schengen Area, has also contributed to the country's transition to an immigrant-receiving nation. Positioned at the southeastern "gate" of the European Union, and with extensive coastlines and easily crossable borders, Greece has become a common transit country for those seeking entry into Europe† (Kasimis 86). Actually, with the development of globalization, migration became very active. Now it plays a very important role and is defined as â€Å"function of changes in the international division of labor and reconstructing of the global economy, which entails rapid and massive movements of productive factors, including capital and labor† (Icduygu 294). The number of immigrants in Greece is very high. Immigrants from Albania amount to around 60% according to the data of the y ear 2012. 1990s were the period of active immigration from Asian states that now is mostly illegal: illegal immigrants usually come from Iraq, Turkey, Afghanistan, etc. There are a number of factors that influence migration. Poverty is considered to be the most important factor that makes people look for better life in a foreign country. The second important factor is armed conflicts in the countries that made people leave motherland and many of them came to Greece that always has been attractive by its geographic location and financial stability. Active immigration from Asian countries has grown into a serious problem for Greece. Moreover, only small part of immigrants is registered, the rest are illegal. The government of Greece is very concerned about the issue as the number of immigrants is becoming so high that it is very difficult to control the immigration. Some actions have already been done in this direction, but the government still can’t establish the appropriate c ontrol over the issue. The absence of legal protection, racial intolerance that inevitably occurs in the society with very high number of immigrants, and bad working conditions turns the foreign labor into exploitation. In general, immigration in Greece is treated negatively and considered to be undesirable and troublesome for the society and economy of Greece. Speaking about natural resources, it is essential to admit, that Greece does not have plenty of them, so import is needed. The main are marble and petroleum. Last time Greece is concerned about the reduction of petroleum reserves. Aluminum, nickel and magnetite can be also found in Greece. In the 1970th Greece was going through the economic development, this period is characterized by active industrialization. Simultaneously, country started facing serious problems connected with environmental pollution. The situation is especially serious in Athens that faces heavy air pollution. Pollution leads to spread of respiratory illn esses and in addition spoils the monuments Greece is so proud of. In order to overcome this problem, the government has to build a number of stations to monitor pollution. These steps helped reduce the pollution. â€Å"Greece should soon begin to see further environmental progress as a result of management and financial efforts made since the mid-1990s. Its environmental policy has been modernized and driven by EU environmental legislation, a search for improved quality of life in the larger cities (Athens, Thessaloniki) and, to some extent, the

The Effects of Economic Aid to Third World Nations Term Paper

The Effects of Economic Aid to Third World Nations - Term Paper Example This question has been repeatedly being asked and emphasized on by various scholars over a long period of period. In 1972, Papanek was the first one to develop a constructive relationship between growth and aid. In 1985, Singh also seconded Papanek that a cohesive relation exists between the economic growth and aid in Third World nations. In 1993, Synder also propagated the ideas of Papanek and Singh but taking into consideration the size of the country. In 1997, Dollar and Burnside acknowledged this positive relation on the premise that it works nicely if the country is meticulous in making policies and it also implements policies according to donor countries, policymakers in beneficiary’s countries and also considers multilateral support firms. In 1999, El-Kaissay and Fayissa profound into this thought and reap the same positive correlation. (Duc) Aids come in several forms; for instance food assistance, military aid, humanitarian emergency support, etc. The growth aid has a lways been recognized as important for helping poor nations of the world to bring them out of impoverishment. The affluent nations of the world decided to give aid of 0.7% of their Gross National Income to poor nations in 1970 as an official global development support each year. But this target has never been achieved. Regardless of the fact that countries have given billions of dollars in cash to poor countries each year they have never met the standard set by them. Some scholars believe that aid has a pessimistic affect on the development of developing countries. In 2000, Knack argued that excessive aid destroys the quality of government, exploits it, and augments the corruption in that region and thus growth is affected negatively. In 2003, Roodman, Levine, and Easterly examined a huge sample size to test the premise of Dollar and Burnside, and the result they found didn’t quite support the positive relation proposed by Dollar and Burnside. (Schoolland) Every rose has a th orn. And thus aid does not come for free. It bears an expensive price to the developing nations. Mostly, the top most condition for aid is that the recipient country must buy over expensive services and goods from the donor nations. Also, the amount of aid is planned and set by affluent countries that following their protectionist policies restrict poor nations to access the market. Most assistance does not really go to the poor nations who are in most need of it. Furthermore, huge projects or enormous striking strategies are deemed to failure to assist the susceptible as mostly, money is used the wrong way. On the contrary, it has also been observed that developing countries with strong economic policies and high-quality governmental institutions have augmented their growth with aid rather than without it. The Gross Domestic Product of countries receiving aid has increased by 2.7% per capita in contrast to countries not receiving aid, with 0.5% per capita. But, some countries who o nly received some aid have achieved a 2.2& per capita of growth. It all basically depends how the aid is utilized; a sound management and high-support by rich countries leads to 3.7% per capital Gross Domestic Product according to World Bank. (Bovard, 1996) Let’s look at the impact foreign aid has on some countries. The current experience of South Asian countries is exemplary. With foreign aid, Bangladesh has

Globalistation and business enterprise - Essay Example This in turn reduced aggregate demand of goods and services (especially luxuries or those with elastic demand) including housing units whereas demand of necessities remained same. In short, the prices of property units plummeted that adversely affected financial position of aforementioned actors. In short, they suffered huge losses and decline in wealth and signed bankruptcies and declared themselves as defaulters. This not only shattered consumer confidence across US but also in many advance economies and thus resulted in negative economic growth. The developing countries that are dependent on developed West for trade also faced the pinch of economic meltdown and contraction in advance economies. (Shah, 2009) Air New Zealand is top quality air travel services provider at affordable prices that also offers related services such air ticketing, customer handling and commercial cargo handling in Australia, New Zealand, North America, Asia Pacific and European nations. The company faces competition with major airlines such as Qantas, Virgin Blue etc. Indeed, it is a state-owned company as government enjoys more than 70% stake in Air New Zealand.

Leadership Essay Example | Topics and Well Written Essays - 750 words - 37

Leadership - Essay Example This paper compares and contrasts the trait and situation approaches of leadership in terms of applicability and leadership competence. Certain types of qualities make leaders more successful while others deteriorate the effectiveness of their leadership. With the trait approach, leadership concerns itself with the leader’s ability to lead others at utmost efficiency. Examples of traits that include a leader’s decisions are intellect, self-assurance, integrity, and strength of mind. As a result, leadership applicants frequently take personality evaluation exams to identify their best qualities. The primary premise of the situational approach is the influence of leadership processes and skills by situations. Developed by Hersey and Blanchard in 1969, the situational approach is a product of the three-dimensional management style hypothesis. The following paper argues that the trait approach of leadership is more applicable than the situational one because the leader’s qualities matter more than the situation or followers in terms of leadership successfulness. The trait approach is most applicable and helpful because it backs the overall image of leaders being a special type of individuals in society (Daft, 2014). This image popularizes the notion that leaders do extraordinary things, which is important. Society has to view leaders as talented individuals, and the trait approach facilitates this view. Another reason is that the trait approach has extensive scientific literature to support its credibility (Daft, 2014). I find research findings more reliable sources of support than mere uncited information. The trait approach also concerns with just the leader and comprehensively analyzes his or her qualities in the leadership procedure. A fourth reason is the criteria set by the trait approach that new leaders can easily adopt. Fifthly, I find the trait approach a naturally agreeable

REVIEW OF THE PLAY THE 39 STEPS AT THE WALNUT THEATRE - PHILADELPHIA - Essay Example Within this context, gender issue and the conceptualization of femininity emerged as women began to realize their equal importance and rights. Hello, this company is very exploitive as it is exploiting you clients as well as we writers. The second phase of the feminist movement from the 1980 and 1990’s also made it possible to bring the issue of inequality in the world politics. In the academic world too, feminism was adopted by many women who realized they should be given their due share. The concept of feminism since then has become the most crucial and a new disciplinary framework for the studies of the gender issues especially women. Though the feminist movement was started centuries back, yet the impetus of it was felt during the Second World War when the whole economy was transforming from labor intensive towards the technological development.

Essay The song â€Å"Imagine† was written by John Lennon in 1971. John Lennon was a former guitarist in the legendary band, The Beatles. He then came out with his own song that soon became one of the most famous tunes in all of history. The song was written to give the world a more hopeful perspective during a troublesome time instigating a revolution of anti-war movements. The song â€Å"Imagine† was written by John Lennon in 1971 to persuade the audience to imagine a world of peace during a time when the world was filled with war. During the year of 1971, the world was dealing with a great deal of war and violence. This was the time of the Vietnam War, the Cold War between the United States and the USSR, the Ind-Pakistani War creating a dark time in Pakistan during 1971, as well as a war ending in South Asia followed by the establishment of the Sovereign Nations in Bangladesh. During all of these troubles, the world was also filled with a great deal of racial discrimination. Although most of the world was involved in wars and strife, John Lennon decides to write an uplifting song that creates a setting without the struggles of man that lead to violence and giving a whole new perspective to the people that needed it. The song â€Å"Imagine† asks the listener to imagine a world of peace. The main argument this song represents is that if we can picture a world without any reason for violence then maybe we can begin achieve it. John Lennon implies protest with his song by asking the listener to picture a world without religion, possessions, countries, or any other reason for violence. â€Å"Imagine theres no countries, it isnt hard to do. Nothing to kill or die for and no religion, too. Imagine all the people living life in peace.† This part of the song implies protest by asking the audience to imagine a world living as one, without countries or religion to cause any racial discrimination. A slow rhythm made by a piano introduces the song with a soothing tone. The lyrics ask you to imagine a world with no heaven or hell and then to imagine all the people living for today. The music transitions to a more upbeat  tone by introducing drums after this verse in the song. There is also a repetition with the piano beats and the lyrics. When the lyrics asks the audience to imagine something, the piano beat repeats to the slow, soft tempo that was in the beginning. The music and the lyrics work together to create an optimistic yet soft, soothing tone.

Titration Lab Essay Example for Free

Titration Lab Essay Method for Control of Variables 1. In order to control the titration of potassium permanganate, we used the pipette to make the titration constant. We also used the same amount of chemical solutions, with the same flasks, to make the titration as constant as possible. 2. To control the amount of redox in the experiment, we have used the pipette to keep on putting the same amount of drop every time. The pipette made the amount of redox constant for every trial, and made the data more accurate. 3. In order to control the amount of potassium permanganate, we have measured the solution with the same plate and same scale. Since we have used the same materials, the amount used was very close. 4. To control the amount of force put in to mix the solution, I used my right hand for every trial and did not vary the length and procedure to mix. I have mixed the solution 5. In order to control the temperature of the liquids, I have used the same room at the same time. I did not used any air conditioning to change the temperature. Method For Data Collection 1. I have weighed out exactly 2.5 grams of AR ammonium iron (II) sulphate crystals, and dissolved them in approximately 40cmà ¯Ã‚ ¿Ã‚ ½ of sulphuric acid solution with a concentration of approximately 1 mol dm-à ¯Ã‚ ¿Ã‚ ½. 2. I did NOT heat the solution to assist the dissolving of the solution. 3. I made up to 100cmà ¯Ã‚ ¿Ã‚ ½ of the solution into a volumetric flask and mixed the solution. 4. I have used the pipette to pipette 10cmà ¯Ã‚ ¿Ã‚ ½ of the solution into a conical flask and added about an equal volume of distilled water. 5. I titrated this with 0.0200mol dm-à ¯Ã‚ ¿Ã‚ ½ potassium manganate (VII) solution to a faint pink color. 6. I repeated the titration for at least 2 times for accuracy in the data and recorded all the results. Table of Raw Results Table Showing Volume of KMnO4 Used to React With the Solution Initial Reading Final Reading Volume of KMnO4 The error or uncertainty of this data is à ¯Ã‚ ¿Ã‚ ½0.05cmà ¯Ã‚ ¿Ã‚ ½. However, the uncertainty for the volume difference is not à ¯Ã‚ ¿Ã‚ ½0.05cmà ¯Ã‚ ¿Ã‚ ½, but is à ¯Ã‚ ¿Ã‚ ½0.10cmà ¯Ã‚ ¿Ã‚ ½. This is because there are two à ¯Ã‚ ¿Ã‚ ½0.05cmà ¯Ã‚ ¿Ã‚ ½ datas, and if you add them up, you will get à ¯Ã‚ ¿Ã‚ ½0.10cmà ¯Ã‚ ¿Ã‚ ½. Evaluation Improvements: In this experiment, there were several inaccurate results and some mistakes I could have improved. 1. Pipette: For each drop from the pipette, there were same amounts of solutions, but since it is made by human hand, there should have been a slight difference in each drop. 2. Temperature: Although I have done this experiment in one class period, there were slight changes in the weather, causing the temperature to change. This could have affected the data results. 3. Force: The force applied to the solution and the flask was approximately the same, but there were some differences since it was done by humans. Humans never can do the same exact thing over, and so there should have been a slight error. Conclusion My hypothesis for this experiment was correct, because it took about 10 drops to titrate. Although there were some slight errors during the experiment, the experiment itself went fairly well, as there werent any big outstanding errors in the data and procedures. The main aim of this experiment, titration of redox with potassium permanganate, was well presented, and overall the experiment was good. Problem Calculation 1. MnO4- + 8H+ + 5Fe- = Mn2+ + 4H2O + Fe3+ 2. 5 moles of Fe2+ is required. 3. 10cm3 = 0.01dm3 0.02 mol dm-3 x 0.01 dm3 = 0.0002 mol 0.0002 moles of KMnO4 is present. 4. MnO4- : Fe2+ 1:5 0.0002 mol : 0.001 mol 0.001 moles of Fe2+ is present in 10cm3 of the solution. 5. 0.001 mol x 10 =0.01 mol 0.01 moles of Fe2+ is present in 100cm3 of the solution. 6. 1 mole of Fe2+ = 56grams 56g x 0.01 mol = 0.56g 0.56 grams of Fe2+ is in the ammonium iron (II) sulfate 7. Number of moles of ammonium iron (II) sulfate = 39 0.56g/(39mol x 0.1) = 14.4% 8. 1 mol of ammonium iron(II) sulfate = (NH4)2Fe(SO4)2 x 6H2O = 2N + 8H+ 1Fe+ 2S + 😠¯ + 12H + 6O = 392 grams 56g/392g = 14.3% 9. My result was 14.4% and it is almost equal to the correct value which is 14.3%. The difference is only 0.1%. 10. The iron (II) salt might evaporate if I heat it, and will affect the result.

Moral Justifications for Archaeological Excavation Sites

Moral Justifications for Archaeological Excavation Sites Can archaeological excavation of sites not under immediate threat of development or erosion be justified morally? Explore the pros and cons of research (as opposed to rescue and salvage) excavation and non-destructive archaeological research methods using specific examples. Many people believe that archaeology and archaeologists are mainly concerned with excavation – with digging sites.   This may be the common public image of archaeology, as often portrayed on television, although Rahtz (1991, 65-86) has made clear that archaeologists in fact do many things besides excavate. Drewett (1999, 76) goes further, commenting that ‘it must never be assumed that excavation is an essential part of any archaeological fieldwork’.   Excavation itself is a costly and destructive research tool, destroying the object of its research forever (Renfrew and Bahn 1996, 100).   Of the present day it has been noted that rather than desiring to dig every site they know about, the majority of archaeologists work within a conservation ethic that has grown up in the past few decades (Carmichael et al. 2003, 41).   Given the shift to excavation taking place mostly in a rescue or salvage context where the archaeology would otherwise face destruction and the inherently destructive nature of excavation, it has become appropriate to ask whether research excavation can be morally justified.   This essay will seek to answer that question in the affirmative and also explore the pros and cons of research excavation and non-destructive archaeological research methods. If the moral justification of research excavation is questionable in comparison to the excavation of threatened sites, it would seem that what makes rescue excavation morally acceptable is the fact that the site would be lost to human knowledge if it was not investigated.   It seems clear from this, and seems widely accepted that excavation itself is a useful investigative technique.   Renfrew and Bahn (1996, 97) suggest that excavation ‘retains its central role in fieldwork because it yields the most reliable evidence archaeologists are interested in’.   Carmichael et al. (2003, 32) note that ‘excavation is the means by which we access the past’ and that it is the most basic, defining aspect of archaeology.   As mentioned above, excavation is a costly and destructive process that destroys the object of its study.   Bearing this in mind, it seems that it is perhaps the context in which excavation is used that has a bearing on whether or not it is m orally justifiable.   If the archaeology is bound to be destroyed through erosion or development then its destruction through excavation is vindicated since much data that would otherwise be lost will be created (Drewett 1999, 76).   If rescue excavation is justifiable on the grounds that it prevents total loss in terms of the potential data, does this mean that research excavation is not morally justifiable because it is not simply ‘making the best use of archaeological sites that must be consumed’ (Carmichael et al. 2003, 34)?   Many would disagree.   Critics of research excavation may point out that the archaeology itself is a finite resource that must be preserved wherever possible for the future.   The destruction of archaeological evidence through unnecessary (ie non-emergency) excavation denies the opportunity of research or enjoyment to future generations to whom we may owe a custodial duty of care (Rahtz 1991, 139).   Even during the most responsible excavations where detailed records are made, 100% recording of a site is not possible, making any non-essential excavation almost a wilful destruction of evidence.   These criticisms are not wholly valid though, and certainly the latte r holds true during any excavation, not only research excavations, and surely during a research project there is likely to be more time available for a full recording effort than during the statutory access period of a rescue project.   It is also debateable whether archaeology is a finite resource, since ‘new’ archaeology is created all the time.   It seems inescapable though, that individual sites are unique and can suffer destruction but although it is more difficult and perhaps undesirable to deny that we have some responsibility to preserve this archaeology for future generations, is it not also the case that the present generations are entitled to make responsible use of it, if not to destroy it?   Research excavation, best directed at answering potentially important research questions, can be done on a partial or selective basis, without disturbing or destroying a whole site, thus leaving areas for later researchers to investigate (Carmichael et al. 2003, 4 1). Furthermore, this can and should be done in conjunction with non-invasive techniques such as aerial photography, ground, geophysical and chemical survey (Drewett 1999, 76).   Continued research excavation also allows the practice and development of new techniques, without which such skills would be lost, preventing future excavation technique from being improved. An excellent example of the benefits of a combination of research excavation and non-destructive archaeological techniques is the work that has been done, despite objections, at the Anglo-Saxon cemetery at Sutton Hoo, in eastern England (Rahtz 1991 136-47; Renfrew and Bahn 1996, 98-99).   Excavation originally took place on the site in 1938-39 revealing many treasures and the impression in sand of a wooden ship used for a burial, though the body was not found.   The focus of these campaigns and those of the 1960s were traditional in their approach, being concerned with the opening of burial mounds, their contents, dating and identifying historical connections such as the identity of the occupants.   In the 1980s a new campaign with different aims was undertaken, directed by Martin Carver.   Rather than beginning and ending with excavation, a regional survey was carried out over an area of some 14ha, helping to set the site in its local context. Electronic distance measuring w as used to create a topographical contour map prior to other work.   A grass expert examined the variety of grass species on-site and identified the positions of some 200 holes dug into the site.   Other environmental studies examined beetles, pollen and snails.   In addition, a phosphate survey, indicative of likely areas of human occupation, corresponded with results of the surface survey.   Other non-destructive tools were used such as metal detectors, used to map modern rubbish.   A proton magnetometer, fluxgate gradiometer and soil resistivity were all used on a small part of the site to the east, which was later excavated.   Of those techniques, resistivity proved the most informative, revealing a modern ditch and a double palisade, as well as some other features (see comparative illustrations in Renfrew and Bahn 1996, 99).   Excavation later revealed features that had not been remotely detected.   Resistivity has since been used on the area of the mounds while soil-sounding radar, which penetrates deeper than resistivity, is being used on the mounds themselves.   At Sutton Hoo, the techniques of geophysical survey are seen to operate as a complement to excavation, not merely a preliminary nor yet a replacement.   By trialling such techniques in conjunction with excavation, their effectiveness can be gauged and new and more effective techniques developed.   The results at Sutton Hoo suggest that research excavation and non-destructive methods of archaeological research remain morally justifiable. However, simply because such techniques can be applied efficiently does not mean that excavation should be the priority nor that all sites should be excavated, but such a scenario has never been a likely one due to the usual constraints such as funding.   Besides, it has been noted above that there is already a trend towards conservation.   Continued research excavation at famous sites such as Sutton Hoo, as Rahtz notes (1991, 140-41), is justified since it serves avowedly to develop archaeological practice itself; the physical remains, or shapes in the landscape can be and are restored to their former appearance with the bonus of being better understood, more educational and interesting; such exotic and special sites capture the imagination of the public and the media and raise the profile of archaeology as a whole.   There are other sites that could prove equally good examples of morally justifiable long term research archaeology, such as Wharram Percy (for which see Rahtz 19 91, 148-57).   Progressing from a straightforward excavation in 1950, with the aim of showing that the earthworks represented medieval buildings, the site grew to represent much more in time, space and complexity.   Techniques used expanded from excavation to include survey techniques and aerial photography to set the village into a local context. In conclusion, it can be seen that while excavation is destructive, there is a morally justifiable place for research archaeology and non-destructive archaeological techniques: excavation should not be reduced only to rescue circumstances.   Research excavation projects, such as Sutton Hoo, have provided many positive aspects to the development of archaeology and knowledge of the past.   While excavation should not be undertaken lightly, and non-destructive techniques should be employed in the first place, it is clear that as yet they cannot replace excavation in terms of the amount and types of data provided.   Non-destructive techniques such as environmental sampling and resistivity survey have, provided significant complementary data to that which excavation provides and both should be employed.

Narco-Terror: the United States, the Drug War, and the War on Terror

Narco-Terror: the United States, the Drug War, and the War on Terror Introduction The United States has had a long-standing policy of intervening in the affairs of other nations when the country has thought it within its best interests to do so. Since the 1970’s the United States has tried to impose its will on other nations to combat the most pressing political enemy of the day often linking the war on drugs to the matter to stoke support both domestically and abroad. In the times of the Cold War, this enemy was communism and the government tried to make the connection of the â€Å"Red Dope Menace† insinuating drug links with China, Castro’s Cuba, and the Sandinistas in Nicaragua. However, as the world has evolved and communism’s prominence has waned, there is a new enemy whose existence has become intertwined with the drug war. That enemy is terrorism. The connection has gone so far that politicians and journalists have coined a new term to describe the link calling this new problem of our time â€Å"Narco-terror.† This pa per will examine US efforts to control the drug trade and fight terrorism in Colombia, Peru, Afghanistan and the desired and often undesired consequences that have come about because of those efforts. Colombia Narcoterrorism has a long past in the history of Colombia, focusing mainly on the market development of one drug: cocaine. Colombia, with its arid tropical climate and lush land, is an ideal place for the sowing and reaping of the coca plant whose extracts are synthesized into the powder cocaine drug. As Colombian cocaine production skyrocketed in the 1970’s and 1980’s thanks to booming demand for the product in Americas, drug kingpins in Colombia began to wield immense power in the country. ... ...

The Hebrews the Children of Israel Biblical accounts do reflect the history of the Hebrew people.

Animal Farm, by George Orwell :: Animal Farm Essays

The author of my book is George Orwell. The book I am reading is entitled Animal Farm. My book is a fiction book with talking animals. The animals rebel against Jones and his farm and how their food was low and they had to work to much to just make food for Jones and his family. The animals were victorious in gaining control of the farm. Then the pigs slowly take over the farm and slowly turn it back into just what it had been when Jones had been there. The story takes place on a farm in the country side. Old Major is the first pig and the ruler who gives all the other animals hope of a rebellion. Snowball is the pig who actually put the rebellion into affect and started the whole rules and laws to start their own farm. Then there’s Napoleon who kicks Snowball out of the farm and takes over the farm and slowly he turns the farm back into what it had been with Jones with him and his partner pigs getting lots of food for no work and the workers getting little food for a lot of work.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  The story starts with Old Major calling for a meeting of the animals where he tells them of the way animals should live and that he only has a few years left to live, but that the animals must carry out a rebellion one day in the future. So Old Major passes away and one day when the animals had been starved for a few days straight the animals broke into the food room and started eating the food. Jones and his men came out to fight them off, but the animals were to strong for them. The animals drove them out of the farm and declared what used to be called â€Å"The Manor Farm† into what they called â€Å"Animal Farm.† Snowball took over as their new leader and served them good especially when Jones came back with some men and guns and tried to take back his farm and Snowball took control and stopped Jones from winning the fight.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Then Snowball gets an idea that they should build a windmill that symbolizes their farm and could be used for hay storage. Napoleon, another pig who wanted to take rule, said that was a stupid idea and Napoleon went on to plant fake evidence that Snowball

Mine safety and environmental health challenges

1. Sketch some of the cardinal wellness and safety challenges that is faced by a excavation company you are familiar with.The industry has experienced both high effect low frequence events ( catastrophes such as Moura and Gretley ) every bit good as low frequence high events ( such as faux pass, strains and falls ) contribute to the industry ‘s high lost clip hurt rate ( LTIR ) . It has besides had its portion of occupational diseases. Historically, pneumonocosis ( lung disease caused by inspiration of mineral dust ) , asbestosis and mesothelioma have been cardinal countries of concern. Noise, quiver and weariness are issues of important wellness concerns. The direction and control of major jeopardies associated with structural prostrations, fires and detonations are cardinal safety issues of the twenty-four hours.Moura:During the past 40 old ages at that place have been three mining catastrophes in the Moura territory at a cost of 36 lives.The first occurred at Kianga Mine on 20 September 1975. Thirteen mineworkers died from an detonation which was found to hold been initiated by self-generated burning. The mine was sealed and the organic structures of the work forces were ne'er recovered.The 2nd occurred on 16 July 1986 at Moura No 4 Mine when 12 mineworkers died from an detonation idea to hold been initiated by one of two possible beginnings, viz. frictional ignition or a flame safety lamp. The organic structures of the mineworkers, in this instance, were recovered.The tierce of the catastrophes occurred on 7 August 1994 at Moura No 2 Mine. On this juncture eleven mineworkers died as a consequence of an detonation. The mine was sealed and, at this clip, the organic structures have non been recovered.2. What is the model of the mine safety statute law in your state/country?Since Australia is a federation of provinces, each province sets out its ain Torahs, which include its ain regulative criterions for occupational wellness and safety. At get downing, each province was separate and used the old wellness codifications ( i.e. , statute law ) and criterions from the British system. This system relied to a great extent upon really specific ( i.e. , Numberss based ) system which was easy to implement and simple to understand. However jobs ensured as clip and engineering progressed which led to the wellness and safety reform that began in 1972.The Current Framework for Mine Safety in Australia in 3 ways:Regulations under a general OHS Act ( VIC/SA/TAS/NT )In separate Mine Safety Acts and Regulations ( WA/QLD )In separate mine Safety Act and Regulations Subordinate to a general OHS Act ( NSW )Since Victoria is my province, the undermentioned legalization will be used under 3 chief classs given as below.Dangerous Goods ActEnvironment Protection ACTOccupational Health and Safety Regulationsa ) As per Occupational Health and Safety Regulations:Occupational Health and Safety Act 2004. Act No. 107/2004: Enabling act. Sets out the cardinal ru les, responsibilities and rights in relation to occupational wellness and safety ( OHS ) . Occupational Health and Safety Regulations 2007, Statutory Rule No. 54/2007: Specifies the manner in which a responsibility imposed by the OHS Act must be performed, or prescribe procedural or administrative affairs to back up the OHS Act ( eg requiring licenses for specific activities, the maintaining of records or giving notice ) .

This sets out the cardinal rules, responsibilities and rights in relation to Environment Protection Act. degree Celsius ) As per Dangerous Goods Act: This sets out the cardinal rules, responsibilities and rights in relation to Dangerous Goods Act. But here separately they all made for single classs as mentioned.

Robens suggested two cardinal issues were of import in accomplishing high criterions of safety.What are these two key issue?Where in the Act ( or ordinance ) are these two issues addressed in themine safety statute law of your state/country?In 1972, the British Robens study sought to modify the old codifications of pattern utilizing two base principals.The first rule recognised the demand to unite all the difference OHS Torahs under one system. It was proposed that this would be accomplished by making â€Å"general duties† into one opinion ( Robens Report, para 41 ) .The 2nd rule observed that a ego ordinance theoretical account be implemented where workers and decision makers ‘come together ‘ in order addition the criterions of wellness and safety ( Robens Report, para 41 ) .The Federal Government in 1985 passed statute law to organize the so National Occupational Health and Safety Commission ( NOHSC ) ; though , because Australia is a federation, each state/territory has to sign federal statute law in order to for the committee ( NOHSC ) to be apart of the Commonwealth and hence have any legal evidences. Each province reformed OHS Torahs, based on the Robens theoretical account and beyond. In fact, the OHS operates in a three manner system. The first is the general responsibilities which cover all employees irrespective of occupation position ( Internet Explorer, contracted or non ) and require the employee as practically possible to guarantee a safe working environment. The 2nd are the â€Å"provisions in regulations† are compulsory Torahs that are specific to each province. Finally, codifications of pattern are used as counsel which set the criterions for the general responsibility of attention. These aid in puting criterions the responsibility holder is required to place the jeopardies and buttocks and control hazards and hence helps Robens 2nd rule nevertheless there remains some critical spreads.4. What is the chief end of industrial hygiene?List the four key processes that play a function in accomplishing this end.Main end of Industrial hygiene is risk decrease and/or hazard riddance wherever possible.AnticipationRecognitionEvaluationControl of workplace e nvironmental jeopardiesSpecify the undermentioned footingsHazardHazardHazard directionHazard AppraisalProbabilityFrequencyBadnessDoseTLV-TWATLV-STELHazard: A jeopardy is any ‘thing ‘ that may do injury or hurt to a individual or belongings. Besides this is the potency of any agent or substances to do injury, normally ill-health or disease.B ) Hazard: The hazard tells how likely an accident ( An accident is any unexpected or unintended event that may do injury or hurt to a individual or belongings ) will do injury or hurt to a individual or belongings. Hazard is a map of the type of jeopardy times the sum of exposure ( Risk = Hazard x Exposure )Hazards direction: The procedure of ordaining general responsibilities of attention in order to extinguish, replacement, or cut down the likeliness of an accident ( i.e. hazard ) through technology or administrative solutions, or through using personal protection equipment ( PPE ) .Hazard Appraisal: Hazard Assessment is the procedu re by which a particular hazard is quantified or qualified in order to understand how to pull off a specific jeopardy. It is based upon the consequence that a specific jeopardy may hold, the magnitude of the jeopardy ( I, e, how terrible it may be ) , and the continuance that the jeopardy may impact a individual or belongings. The hazard appraisal helps determine how a jeopardy may be managed and how a hazard may be controlled.Probability: the likeliness for an event to happen. One of the factors that serves as the dependent variable for hazard ( I.e. Risk=Probability * Severity ) orIt is a manner of showing cognition or belief that an event will happen or has occurred. In mathematics the construct has been given an exact significance in chance theory, that is used extensively in such countries of survey as mathematics, statistics, finance, gaming, scientific discipline, and doctrine to pull decisions about the likeliness of possible events and the implicit in mechanics of complex s ystems. degree Fahrenheit ) Frequency: Frequency is the rate at which a individual may come into contact with a jeopardy over a defined length of clip. Or The figure of times that a periodic map repeats the same sequence of values during a unit fluctuation of the independent variableBadness: Badness is the magnitude, or strength, with which a risky substance is exposed to a individual. It is the dimension for sorting earnestness for Technical support issues.Dose: Is the sum of the jeopardy which we are exposed. It is defined by the concentration of the risky substance times the length of clip a individual is exposed.Dose is the construct of dosage is paramount for occupational hygiene and hazard direction. Dose refers to the sum of a substance to which we are exposed, and is a combination of the concentration of exposure and continuance of exposure. Dose= concentration*duration of exposureI ) TLV-TWA:TLV values by and large refer to a national exposure criterion for a jeopardy ( i.e. chemical, dust, or radiation ) . It is a agency of quantifying the maximal concentrations of a peculiar substance in an country over a specified length of clip, and so using it as a criterion for wellness and safety inspectors and responsibility bearers to utilize as a manner of measuring hazard. TWA is an acronym for clip leaden norm. In this instance, the continuance of contaminant exposure is expressed over an eight hr working twenty-four hours and a five twenty-four hours working hebdomad. In this manner, this exposure criterion incorporates the upper limit and minimal exposure rates a individual experiences during a regular on the job twenty-four hours. The accent of an exposure free clip is implicitly involved ( as would be the instance for noise ) so that certain organic structure thresholds are non passed.J ) TLV-STEL:STEL is an acronym for short term exposure bound. For some substances, a short term exposure criterion is needed since ague and chronic wellness affects may ensue. Alternatively of an eight hr twenty-four hours, this exposure criterion is step over no more than 15 proceedingss.6. Whatare the chief airborne contaminants/pollutants that can do health-related jobs at mine sites?The Dust and particulates ( arsenic, lead, quicksilver and etc ) ;The Toxic gase s ( C monoxide, sulfur dioxide and etc ) ;The Carcinogens ( asbestos, aromatic hydrocarbons, and etc ) ;The Flammable gases ( methane and C dioxide and etc ) ;The Radiation toxicant ( radon, U, Th and etc ) ;The Mixture of viruses and bacteriums.7. For a peculiar legal legal power ( state/country ) what are the legal demands for the concentration of the followers in the general organic structure of airing air flow ( maximal or lower limit ) ?Harmonizing to the HSISa ) Oxygen Pure O: no limitations Oxygen diflouride: TWA=.05 ppm B ) Methane ( as a gas ) Pure methane: TWA=0, STEL=0 Bromomethane: 5ppm STEL=0 degree Celsiuss ) Carbon dioxide In coal mines: TWA= 12,500 ppm STEL= 30000 ppm Regular: TWA= 5000 ppm STEL= 30,000 ppm vitamin D ) Carbon monoxide: TWA= 30 ppm STEL=0 vitamin E ) Hydrogen sulfide: TWA= 10 ppm STEL= 15ppm degree Fahrenheit ) Respirable dust ( no silicon oxide ) Coal Dust: TWA = 3 mg/ M3 STEL=0 Soapstone: TWA = 3 mg/ M3 STEL=0 Vanadium: TWA = 0.05 mg/ M3 STEL=0 Graphite: TWA = 3 mg/ M3 STEL=0 g ) Respirable dust ( with silicon oxide ) : TWA= 2 mg/m3 H ) Oxides of Nitrogen: Nitrogen Triflouride: TWA= 10 ppm STEL=0 Azotic Oxide: TWA= 25 ppm STEL=0 Azotic Oxide: TWA=25 ppm STEL=0 Nitrogen dioxide: TWA= 3ppm STEL=0 Nitrogen tetroxide: TWA= 0 STEL=08. Define Dust, list and briefly describe the general preventive steps, which can be used to command or forestall exposure to high dust exposures.Dust caused by the mechanical decomposition of stuff can be defined as a aggregation of solid atoms which:Are dispersed in a gaseous medium ( normally air )Are able to stay suspended in the air for a comparatively long clipHave a high surface country to volume ratio.So briefly, over the full scope of airborne stuffs, dust by and large has the largest atom size although it can exhibit a broad particulate scope. In general, dust can be defined an merger of assorted particulates ( solid affair ) that can divide and stay in suspension in air. Dust is by and large caused by mechanical weathering through, in the instance of mines, the usage of really big machines ( drills and crushers ) and blasts. Dust can either present an immediate jeopardy ( I, e, oculus annoyance ) or long term wellness effects ( radioactive atoms that stick to respirable dust which are later inhaled ) . Whether the effects are long term or short term, there are a figure of ways that duty callings can command or even extinguish dust. 1 ) Preventative steps ( Elimination ) :This is the best manner among all.This includes irrigating to cut down dust formation when film editing and boring ; guaranting that cutting equipment is crisp, and utilizing oils to transport mine cuts to an enclosed country.Under these conditions, â€Å"the means of control† is through riddance.A concluding piece of equipment is a unsighted hole bore bit which traps the dust generated through an enclosure.2 ) Ventilation ( Engineering ) :This is an technology agencies of control dust through a proper airing system.Here the air must be able to be strong plenty to pick up the heavy dust atoms to cut down the sum of dust concentrating in the air or on the land.Dust extraction and filtration systems that pump in the ‘dusty ‘ air, filter out the atoms and so throw out ‘cleaner ‘ air.3 ) Removal of employees ( Administrative ) :This is an administrative attack where the employees are fundamentally removed from the jeo pardy thereby extinguishing exposure.This is frequently non really practical, particularly in medium/small operations, or in rural operations where all employees are needed, or working rotary motion is non an option.4 ) Use of inhalator ( PPE ) :This is the least manner control nevertheless we have no other option.Here a worker uses a inhalator in order to filtrate out the dust, thereby understating hazard by cut downing exposure.However, many inhalators can be excessively heavy or cumbrous to cover with, particularly belowground.9. Discourse how methane is generated in mines. What are the cardinal hazards associated with methane, and how can the hazards be managed?Methane coevals in mines:This is produced by bacterial and chemical action on organic stuff and is evolved during both the formation of coal and crude oil. One of the most common strata gases. It is non toxic but is unsafe as it can organize an explosive mixture with air. A methane/air mixture normally called firedamp. Methane is normally associated with coal mines but it is besides normally found in other mines which are over or underlain by carbonous formations. Methane is retained within breaks, nothingnesss and pores within stone either as a tight gas or adsorbed on mineral surfaces. When mining disturbs the stone the gas force per unit area gradient set up between the reservoir of methane and the airing system induces flow of methane along natural or excavation induced breaks towards the gap.Key Hazard:Methane has no smell, but it is frequently accompanied by hints of heavier hydrocarbons in the paraffin series, which have a characteristic oily odor. The denseness of methane is a small over half that of air. This gives rise to the danger of methane layering in pools along the roof of belowground gaps. The perkiness of methane can besides do jobs in inclined workings. Methane Burnss in air with a pale blue fire. The explosible scope for methane in air is by and large quoted as 5-15 % with maximal explosibility at 9.8 % . The lower bound remains reasonably changeless, the upper bound reduces as the O content of air falls. To track the flammability of methane air mixtures a coward diagram as shown in figure 2 can be used. With relation to calculate 1: Figure 1: The coward diagram for methane in air.In zone A the mixture is non flammable but is likely to go so if farther methane is added.In zone B the mixture is explosive and has a lower limit nose value at 12.2 % OZones C and D illustrate mixtures that may be in certain countries.Methane beds have two chief jeopardies associated with them:Layers extend the zones within which ignitions can happenWhen an ignition occurs the methane bed acts as an effectual fuse along which the fire can propagate, sometimes taking to much larger accretions in roof pits or in the mariner.Methane and Carbon dioxide ( mixtures of the two gases ) if mixed with N will do the dangers atmosphere. Because this associated with gas effusions are:Suffocation of mineworkers by gas and dust. Compressed air line of lifes may be maintained on or shut to faces that are prone to effusions.The force of the effusion may damage equipment, doing triping that may light the extremely flammable gas/dust mixture.The sudden e nlargement of a big volume of gas can interrupt the airing system of the mine.To command and Manage:To command and pull off the hazard of Methane, foremost of all demand to cognize the beginnings and nature of methane, and how the methane is let go ofing and migrating. And so apprehension of hazards can easy take to larn of the methane hazard direction. The major systems as follows,In its of course happening province in a coal seam, firedamp does non represent an explosive hazard. However, where firedamp released from next seams meets â€Å" fresh-air † in the goaf, the firedamp is diluted and explosive mixtures ( around 5 % to 15 % methane in air ) are formed. Effective firedamp control is indispensable for safe working and involves supplying either:Face-End Ventilation and Gas Control: good designed Ventilation flow avoid the hazard of methane gas.Firedamp Drainage on Retreat Longwalls: Firedamp gaining control efficiencies on longwall faces typically lie between 60 % and 8 0 % of the entire gas on progressing faces and from 30 % to 60 % of the entire gas on retreat faces. Options and Addendums to Firedamp Drain: There are airing options applicable to some retreat longwall coalfaces which can rid of the demand for dearly-won firedamp drainage. Such methods ( eg. hemophiliac roads and sewer gate systems ) are aimed at deviating gas off from working coalfaces along paths separate from those used to serve the face. Goaf Flushing: Goaf flushing has been used for temporarily betterment of firedamp concentrations in a territory return but it is non a recommended gas control solution. The method is by and large applied to a fully-developed goaf ( Internet Explorer. where sufficient goaf has been created to organize a significant gas reservoir ) . The airing force per unit area across a territory is reduced, after work forces have been withdrawn, leting high gas concentration gas to migrate frontward into the return airway. Transport activities in the chief return may hold to be suspended. Finally, the equilibrium between gas flow into the waste and gas flow into the return is restored, the gas concentration in the territory return being at a higher concentration than earlier due to the reduced air measure. On reconstructing the original air flow, the gas is forced into the goaf, off from the face, therefore cut downing the emanation into the return until equilibrium conditions are one time once mor e obtained. This attack is non advised due to the uncontrolled release of elevated firedamp concentrations into air passages and across electrical equipment.Methane Drain: To bring forth gaseous fuel and/or to cut down methane emanations in to airing system its been used. Methane that is drained demands to be transported safely to the point of bringing, the substructure that is required to accomplish this consists of the followers: Pipe ranges, Proctors, Safety devices, Controls, Extractor pumpsOther than all above mentioned, in single states they are following up regulations and ordinances to command and pull off the hazard of Methane. Here is an illustration UK statute law provinces,Electrical power must be switched off when the general organic structure concentration of methane exceeds 1.25 % .If methane concentration exceeds 2 % forces other than those associated with bettering the airing in the country should go forth the country.10. Discourse the beginnings and hazards associa ted with arsenic, quicksilver and nitriles. How can the hazards be managed?A ) quicksilver Beginnings:Natural beginnings:VentsVolatilization from oceansErosion of natural sedimentationsHuman Activities:Estimated to be 1/3-2/3 of the entire quicksilver released into the environment.Beginnings include:Stack losingss from cinnabar roastingThe working and smelting of metalsCoal fired power workssDischarges from mines, refineries and millsCombustion of coal and municipal wastes, industrial wastes and boilersMedical waste incineratorsPesticidesOverflow from landfills/croplandsB ) quicksilver Hazards:Continuity:Can alter signifier,Can non be destroyedSolubility:Cinnabar ( HgS ) is indissoluble ( and resists enduring ) ;Liquid Hg is somewhat soluble in H2O.Bioaccumulation:Hg methylation signifiers CH3Hg+ which is easy absorbed by beings and biomagnifies from the underside to the top of the nutrient concatenationBioaccumulates ( dressed ores ) in musculus and tissue of fish and other wildlif eCH3Hg+ by and large increases by a factor of 10 or less with each measure up the nutrient concatenationC ) Arsenic Beginnings:Arsenopyrite ( FeAsS ) is the most common arsenic mineral in ores and is besides a by-product associated with Cu, gold, Ag, and lead/zinc excavation.Arsenic trioxide ( Fe2As3 ) is present in flue gases from Cu ore roastingcoal-burning power workss and incinerators besides may let go of As into ambiance.Water: mean concentration is 1 ppb, but can be & gt ; 1,000 ppb in mining countries ; As+5 most prevailing ; many compounds dissolve in H2O.D ) Arsenic Hazards:Arsenic is a human carcinogenIn worlds the primary mark variety meats are the tegument and vascular systembirds, animate beings, workss, and freshwater fish can go contaminatedToxicity in H2O is determined by H2O temperature, pH, organic content, phosphate concentration, suspended dirts, presence of oxidizers, and speciationTocopherol ) Cyanides Beginnings:Can leach from landfills and cyanide-containing route salts every bit good as to the ambiance from auto fumes ( hydrogen nitrile gas – HCN ) .Some nutrients ( Prunus dulciss and lima beans ) contain nitriles of courseIt can be produced by some bacteriums, Fungis, and algaeSpills: Cyanide and other heavy metal pollutants overflowed a dike at Baia Mare, Romania, polluting 250 stat mis of rivers, and killing 1000000s of fishMost persistent in groundwater & A ; at higher pHF ) Cyanides RisksOral lethal dosage of KCN for an grownup is 200 milligramAirborne concentrations of 270 ppm is fatalLong term exposure to lower degrees consequences in bosom strivings, take a breathing troubles, purging, blood alterations, concerns and thyroid secretory organ expansionCN does non bio-accumulate in fishG ) Cyanide hazard Control Methods:Production: Encourage responsible nitrile fabrication by buying from makers who operate in a safe and environmentally protective mode.Transportation system: Protect communities and the environment during cy anide conveyance.Managing and Storage: Protect workers and the environment during nitrile handling and storage.Operationss: Manage cyanide procedure solutions and waste watercourses to protect human wellness and the environment.Decommissioning: Protect communities and the environment from nitrile through development and execution of decommissioning programs for nitrile installations.Worker Safety: Protect workers ‘ wellness and safety from exposure to cyanideEmergency Response: Protect communities and the environment through the development of exigency response schemes and capablenesss.Training: Train workers and exigency response forces to pull off nitrile in a safe and environmentally protective mode.Daily review of leach residue storage pools and shadowings bringing grapevines ;Incident coverage and a system of exigency processs ;Systems for informations recording, rating, reading and coverage ;Procedure technician preparation and consciousness of possible nitrile related j obs, including personal safety and impacts on the environing natural environment ;systematic records direction and certification of carnal mortalities ;Integrating cyanide direction processs into the site Environmental Management Plan which is presently being updated.H ) Arsenic and quicksilver hazard control methods:The above mentioned methods are suited to follow Arsenic and quicksilver every bit good. However in practical universe, it depends upon the harmness, will change to importances of handling.11. Specify the intent of airing in belowground mines. What types of airings systems are common?The intent for airing in mines is to thin assorted signifiers of gases. These gases could be either a chemical jeopardy ( as in carbon-monoxide and dust ) or explosive physical jeopardies such as methane accretion along the roofs of mine shafts. Ventilation systems frequently come in the signifier of,fans which control air flowarrests and seals will seal escapes in peculiar to older minesDoors and air locksRegulators which is a door with an appropriate transition to keep air force per unit area gradientsAircrossings which allow suction and blowing airing systems to easy by base on balls one another and non let for cross taint12. Electrical power is normally employed in mines, what work patterns would you specify for the care of electrical equipment?Always to be Maintained, reviewed and modified mine power supply systems.Make certain Consistently inspect machineraries and carry out trials for mistakes and jeopardiesMake certain ever the electrical equipment is decently viewed, so that arrange some visible radiations near electrical equipment in belowground mines to guarantee to be seeable.Make certain while Create processs to guarantee noise and electrical jeopardies ; over electromotive forces, current ordinance, noise degre e decreases etc. , are maintained to allow legislative criterions.Without excessively much emphasis, seek to supply machinery that can be moved easy that are besides within legislative demands and can provide equal electricity Create an alternate power supply beginning in instance of machinery dislocation which allows to make care activities. For the speedy designation, install proper mine overseas telegrams with appropriate coloring materials coding system. And following safety regulations and ordinances besides makes the good work patterns for the care of electrical equipment.Failure to exert cautiousness may ensue in hurt, so cautiousness must be used when runing or mending electrical equipmentWhen executing electrical work, ever use the proper protective equipment, such as: safety spectacless, protective baseball mitts, and a decently rated metre.State ordinances, Australian Standards and company policies are designed to guard against electrical jeopardies in the excavation industry. So following up those are really indispensableWet conditions may eat metal electrical constituents and do their failure. Falling stone may damage an electrical overseas telegram or constituent. So need to avoid those sort of unsafe conditions before put ining at specific topographic points or demand to take attention to avoid those jobs.Exercise cautiousness to be used to utilize proper protective equipment when working with batteries. Because batteries could detonate and do hurt or could light and do fires.All have to be cognizant and particularly all electrician decently trained to Be watchful and knowing of the jeopardies of electricity.Make certain ever maintaining attitude tono electrical work can be performed until the electrical circuit is knocked, locked, and tagged.Always make certain the frame land is decently connected.No electrical work shall be performed except by a qualified individual. Circuit surfs and gulfs shall be marked for designation. Circuit interrupting devices or proper fuses, shall be installed to protect against short circuit and overloads.u Unpluging devices shall be locked and tagged out. All electrical equipment shall be examined, tested, decently maintained, and consequences recorded as required13. Your mine employs grapevines to convey the followers:Compressed airService H2OMethaneRun of mine drainage H2OHow would you guarantee that each grapevine can be readily identified by a speedy ocular review?C oloring the pipes with different sort of colorss may give solution to this instance. Examples:Blue coloring material for service H2ORed coloring material for Compressed airGreen coloring material for MethaneYellow coloring material for mine drainage H2OThis manner each pipe is easy visualised in the mine. A mark that demarcates the coloring material coding system will besides be necessary to clear up the coloring material cryptography system.14. Distinguish, with the usage of illustrations, the difference between major, chronic and minor incidents. What are the legal demands for describing these different types of incidents in your legal power?Incident is a happening of an event that has a non human component to it ( unlike accidents ) . Major incidents: Are sudden alterations which are dramatic, necessitate immediate responses, and are by and large dearly-won and a figure of human deaths. An illustration is methane gas effusions in belowground coal mines. Examples:Major fire, detonationFatalityStructural prostrationMajor equipment harmMajor loss of productionTypically cost 1000000s of moneysChronic Incidents: Are events that result in an hurt ; is related to a figure of causes, and have effects that are lower in magnitude and strength than major incidents. Sometimes these events may do change in the normal processs in mines. Examples:Recuring quality divergence.Recuring equipment failure.System corrosion/erosion.Fleeting emanations.Slips, trips and falls.Minor Incidents: Or near miss incidents which do non involved in any loss or hurt but if a different event occurred, could do hurt or injury. When these incidents happened, the legal demand is 5 stairss:ReportingGathering the FactsDetermine Cause ( s )Develop and Implement Corrective ActionMonitor and Review15. Discourse four theories of accident causing.1. Domino theory:It is developed by Herbert Hinrich ( Travelers Insurance Co ) in 1920.Says that hurts occur from actions that interact. The hurts are caused by insecure Acts of the Apostless by workers and are by and large preventable given proper safety preparation. It includes:Injuries arise from a set of complete actionsMost hurts arise from insecure Acts of the ApostlessAccidents are mostly preventableInsecure Acts of the Apostless can hold ulterior effects vs immediateManagement should take controlHarmonizing to Heinrich, five factors can take up to an accident:Lineage and societal environmentMistake of a individualInsecure mechanical or physical state of affairssThe accident itself ( falls, being hit )Injury: Typically lacerations and breaksUnder this rubric, direction should take control and supply safety to workers.2. Human Factors Theory:Accidents are caused by human mistake under three chief factors:Overload ( instability in a individuals capacity )Inappropriate Response: How a individual responds to a state of affairsInappropriate Activity: Human mistake in judgement, action, way, etc. )3. Accident and Incident Theory:Asper this theory, the environment is a cause alternatively of human mistake. The design and excessively high of outloo k in work end product are the causes of accidents. Therefore, there is an indirect influence of direction and economic factors ( deadlines, agenda, budget, peer force per unit area etc. ) that can take to bad judgement and therefore accidents. The Accident and Incident Theory proposes a causal relationship exists between direction clime and focal point, and accident causing.4. Epidemiologic Theory:Accidents are caused bysensitivity features ( cultural, physical charecteristics, societal norms )Situational characterisitics ( unequal preparation, small counsel, or direction â€Å"climate† ) .Under this theory there is a causing nexus between the environment and societal or mental factors. The Epidemiology theory holds that theoretical accounts used for survey and finding of disease can be utilized for accident causing as good16. ( a ) What is occupational hearing loss?A signifier of hearing loss due to the disfunction of the auditory nervus, ( i.e. hearing loss ) that is caused by the overexposure to noise degrees of high strength ) . This is besides called acoustic injury hearing loss( B ) Define the footings frequence, strength, dubnium, dubnium ( A )Frequency: The rate at which sound atoms vibrate through an elastic medium that the ear can comprehend as ‘sound ‘ .Frequency = Cycles per Second = Hertz = Hz 1000 Hz = 1 Kilohertz = 1 kilohertz = Human Voice Intensity: Intensity is the sum of energy going through a unit volume of air during a certain timeframe. dubnium: The dB ( dubnium ) is a logarithmic unit that indicates the ratio of a physical measure ( normally power or strength ) relation to a specified or implied mention degree. Amplitude = Loudness = Decibels = dubnium 60 dB = Average Speaking Voice dubnium ( A ) : It is the frequence response curve which is resembles the normal frequence hearing curve for most people. A metre utilizing this web will give a consequence which does hold some resemblance in degree to that degree which is experienced by most people The other manner we can state that, Noise is measured in dBs ( dubnium ) at a certain graduated table, such as A or C. The dB graduated table is logarithmic. That means, with a 5dB exchange rate, 95 dubnium is 100 % more noise than 90 dubnium.( degree Celsius ) Define the term Daily Noise Dose ; what factors influence this?Daily Noise Dose:The Daily Noise is an exposure criterion that measures the grade a individual working is able to be exposed to resound. Worksafe states that a degree of 85 dubnium ( S ) ( ie not additive criterion ) over 8 hr twenty-four hours ( much like the clip weight norm ( TWA ) exposure standard ) should non be breached, nor a peak degree of 140 dubniums at any specific clip should non be breached ( much like the TLV-STEL ) . If exposure to resound is to happen above these degrees a step of control upon noise is required. Harmonizing the National Institute for Occupational Safety – NIOSH – the day-to-day dosage degree – D – should non be or transcend 100. When the day-to-day noise exposure consists of periods of different noise degrees, the day-to-day dosage can be calculated as: D = ( te1 / td1 + te2 / td2 + †¦ + ten / tdn ) 100 % ( 1 ) where D = day-to-day noise exposure ( % ) Te = exposure clip at a specified noise degree td = maximal continuance clip at a specified noise degree The day-to-day dosage can be converted to an 8-hr Time-Weighted Average -TWA by the expression TWA = 10 log ( D / 100 ) + 85 ( 2 )

Construct the Efficient Frontier

Construction a. Estimation The goal is to obtain the raw ingredients – expected returns, standard deviations and correlations. Historical data are used for this purpose. As a rule of thumb, five years of daily data are probably right (one year should be the absolute minimum). Keep in mind the following: 1) make sure to use the adjusted close prices to calculate returns (so that you won’t have large, spurious negative returns due to dividend payments or splits), and 2) calculate log returns (so that you can aggregate daily returns to obtain holding period returns, if ever needed).In Excel, the function for mean and standard deviation are â€Å"= average (range)† and â€Å"stdev(range). † To calculate the correlation matrix, use â€Å"correlation† under â€Å"data analysis. † Please note, in practice, the estimates can be adjusted in view of economic outlooks. This is especially so for expected returns. Sometimes, the realized historical return s are negative or below the risk-free rate. They must be adjusted upward – who would ever buy a stock and expect to receive a return less than the risk-free rate (if the beta is not negative)!? II.Efficient frontier construction Step 1. Variance/covariance matrix, The expected return and variance for the portfolio are: You can think of the variance as the â€Å"weighted average† of all the covariances, ? i? j? ij where the weights are xi and xj. Of course, the variance terms are special cases of the covariances when i=j, and ? ij=1. You can calculate the portfolio variance in the spreadsheet in many different ways. The way I do it is to first calculate the variance/covariance matrix, whose entries are ? i? j? ij and ? i2. To this end, we first construct the tandard deviation (std) matrix and the correlation matrix, as shown in the spreadsheet. Then, first multiple the std matrix to the correlation matrix to obtain (multiply the range of b3.. g8 to the range of b10.. g15). Then, multiple matrix to the std matrix again (multiply the range of b17.. g22 to the range of b3.. g8) to obtain the variance/covariance matrix in b24.. g29. Step 2. Portfolio's return, variance, standard deviation and slope To obtain the portfolio variance, we need to further multiply each entry of the variance/covariance matrix by their corresponding weights, xi and xj.Remember, those n portfolio weights are what we are trying to solve for. So we put them in a column (a34.. a39). To facilitate the calculations, I also place the weights at the top of the matrix. The variance/covariance matrix is simply copied from Step 1. Since we will also need the security returns to calculate the portfolio return, they are placed in j33.. j39. Now, we multiply the weights to each column of the variance/covariance matrix using the function â€Å"=sumproduct. † This â€Å"sumproduct† results in each weight in (a34.. 39) being multiplied to each entry in the variance/covarian ce column, and then all summed up. The variance/covariance terms will have only one weight being multiplied to. So we need to multiply this sum by another weight at the top of the matrix (remember: multiplying the sum by something is equivalent to multiplying each individual item by the same thing). Summing all the items in b40.. g40, we obtain the portfolio’s variance, and taking square root of it, we have its standard deviation, in cell b45. The portfolio’s return in b44 is calculated as the weighted average of individual security returns.The slope of the CML is simply the rise (i. e. , portfolio’s return minus the risk-free rate) over run (i. e. , the portfolio’s std). Step 3. Obtain minimum variance portfolio: minimize STD subject to sum of weight = 1. 0 The minimum variance portfolio is the one that has the lowest variance among all possible portfolios. We use the â€Å"Solver† in Excel to find this portfolio. We would like to vary the weights in a34.. a39 so that the variance (or equivalently, std in cell b45) is minimized. In the â€Å"Solver,† enter b45 as the target, and choose â€Å"min. The range for â€Å"Changing cells† should be a34.. a39. The only constraint is: all the weights sum to one, i. e. , set cell b42 equal to 1. 0. Then simply click on â€Å"solve. † The solutions will be in a34.. a39. Of course, the portfolio’s return and std are simultaneously calculated in cells b44 and b45, and the slope linking the portfolio and the T-bill is in cell b46. Step 4. Obtain market portfolio: maximize Slope subject to sum of weight = 1. 0 Follow the same logic/procedure as in Step 3, except that you want to maximize cell b46. Step 5.Obtain market portfolio with no short selling: maximize Slope subject to sum of weights = 1. 0 and all weight being positive This part is just for completeness: to show you how to construct the market portfolio when short selling is prohibited. Here you also ma ximize cell b46, except that, aside from the weights-summing-to-one constraint, you would add six more constraints: a34 ;gt; 0, a35 ;gt; 0, †¦, a39 ;gt; 0. It turns out that, the weights on Securities 2 and 3 are zero, since they command the most amount of short selling in the unconstrained case (Step 4).However, it is not always true that any security that is being shorted in the unconstrained case will have a weight of zero in the constrained case. Security 5 is a case in point. Step 6. Generating efficient frontier Here, everything is already self-explanatory. Essentially, we need to plot the parabola and the CML. To this end, we first get the functions for each, and then use Excel to generate some points (50 in my example) within the reasonable range of returns and std.

Analysis Vission and Mission of Coca-Cola Essay

In general, Coca-cola vision guides all members to understand what the company does, how it is done, and who it is done for also keeps the employees focused on the realistic goals of the firm, customers, investors, and other business partners. An effective vision should consists of two component which the first one is a cognitive component; which focuses on outcomes and how the best to achieve it, and the second component is affective component which will helps to motivate people and gain their commitment toward it( Boal and Hooijberg 2001). Base on Coca-cola vision statement show that they apply the affective component which increasing motivation and commitment among their employees, customers and business partners. The six P’s of Coca-cola vision which is People,, Portfolio, Partners, Planet, Profit and Productivity is the guideline to increase motivation and commitment. These six P’s also clearly mention the desirable future target for each component internally and externally of the firm, which is among people (employees), portfolio (product), partners (customers and suppliers), planet (moral obligation), profit and productivity. These visions also challenge all to participate and reach the organization goals. As a good vision, the internal (organizational beliefs and values) as well as external (shared understanding of the market environment) needs to be aligned. Besides, the Coca-cola vision statement also focuses on how the organizational members relate to the vision and shared each others. †¢People: Be a great place to work where people are inspired to be the best they can be. †¢Portfolio: Bring to the world a portfolio of quality beverage brands that anticipate and satisfy people’s desires and needs. †¢Partners: Nurture a winning network of customers and suppliers, together we create mutual, enduring value. †¢Planet: Be a responsible citizen that makes a difference by helping build and support sustainable communities. †¢Profit: Maximize long-term return to shareowners while being mindful of our overall responsibilities. †¢Productivity: Be a highly effective, lean and fast-moving organization This is a good sample of vision statement because it’s not too specific and realistic to achieve by all their members. This vision statement also encourages all members to participate in achieve the vision.
