The measurement using the the buret have a +/- . 1mL error. These types of measurement error are based on the sensitivity of the instrument, du ring the measurement. These errors could cause the result to deviate from the actual answer. During the experiment, using titration to find the end point. Because of the end point was unknown, a single drop could determine its end point. There might be an extra drop that caused the data to vary as both parts of the experiment have determined. The first trial of both the experiment, the number is different, because of the unsure number of drops. Using the result from the first trial, the result of the second trial was more accurate. As proven from the experiment of determination of percent of MgO of the unknown. The sample 2 and sample 3 testing results in similarity that differ from the sample one. The sample used 73. 0 ml of the EDTA solution, while both samples 2 and 3 used 74. 2 ml of EDTA solution. This will cause a tip in the result toward a lower number used to find the end point. This error is not a major factor since it is only of my 1. 2 ml of the actual result. The percent of all three result of MgO is different under 1 percent different. Thus, a very reasonable result in all three of the experiment. Discussion: This experiment is to help us understand the reaction between an anion and the metal cation. It demonstrated the Lewis base understanding of ethylenediaminetetraacetic acid (EDTA). The goal was achieved through titration of the sample in multiple trials in order to find its endpoint. The end point was found when the pink coloration, due to EBT was added, turn into a blue/ violet color. This signified its endpoint of the sample. The result is good quality, because of the deviation from the first trial and last trial that was done on the same sample. The result is off by . 2ml in the standardization of EDTA solution. In the second part of the determination of % MgO of the unknown; the first, second, and third sample the percentage displaces is well under 1% difference. The result is worth 99% confident that the result is good quality, because of the consistency of the data. How to cite % Mgo Determination, Papers

Question: Discuss about theHuman Resource Analytics. Answer: Introduction Gold is a precious metal in this world because of its various applications. Therefore, understanding the way its prices are affected could be valuable to the investors. The gold prices are subject to external factors that affect the general pricing of gold throughout the world. Gold has been there for thousands of years and yet it has remained to be of value even today. That makes it an integral piece of the worlds economy. When gold prices go up, important aspects of the economy are affected such as fuel prices, food prices and so on (Rong Lijian 2008). Therefore, having knowledge regarding what affects the gold prices will aid the investors in beforehand preparations and insulation against trying economic times. The availability of gold is the primary factor that results in the fluctuation of gold prices. There are other factors, which this essay will address, that affect the gold availability, and in turn, they affect gold prices. Continuing Factors Iranzo et al. (2007) believe that availability of Gold affects the prices of gold. Whenever gold is in plenty, the prices of the gold will go down. The reduced prices are as a result of the increased rate of substitution. Since there are many points where the clients can get the gold, the gold sellers have less control over he prices. During times of scarcity, the gold prices will increase because of the low rate of substitution. Looking at the seasonality charts (See appendix 4), gold prices are high at the period after the May 5th all the way to December. After that, the prices are low after December until May creating a season. One such time when the gold prices are down is during a global crisis which results in the low confidence of investors in financial markets or governments. World events affect the gold prices because they affect the availability of gold in the world. When the Russians moved into Ukraine, the prices of Gold increased because the geopolitical instability was affecting the production of the metal. That increased the scarcity of the metal. One-Off Factors Gold prices are also affected by the demand and supply factors of its market. Gold is a metal known for its high demand since it has numerous uses. It can be used to create priced beauty ornaments that fetch extremely high prices. The metal is also an industrially preferred metal because of its high resistance to corrosion. That means it is long lasting and increases the productivity of the industries. Moreover, it has a high thermal and electrical conductivity making it even more precious to the industrial market. Manheim (2010) asserts that gold has a finite supply which means that it is a very scarce resource. Whenever it becomes available in the market, it is purchased at a faster rate. The high demand leads to under-supplication of the commodity. Because of the scarcity, the prices will increase. The charts show this effect between December and January (see appendix 3). As the year ends, the demand is high but the supply keeps on decreasing because the Gold is quickly purchased off the market. Central bank reserves are also a primary input in the prices of gold all around the world since they hold gold and paper currencies in their reserves. The purpose of doing this is to maintain the supply of these commodities in the market. When gold is in excess within the economy, there could be inflation which may occur (Roosma Saar 2012). Following appendix 2, it can be seen that the demand is high following the increased prices. As the gold is purchased from the market, the prices increase which show the effect that the Central Bank has on the gold prices. In a bid to avert the potential inflation, the Central Bank will buy gold from the economy and put it in storage. That will reduce the flow of these commodities in the market. That is why there is a seasonal pattern of gold prices for about twenty years where gold prices are low until May 5th but rise again from then to about December 5th. That is called the gold season seasonality. The mere fact that it occurred for the last t wenty out of thirty years increases the reliability and validity of this assertion. Interest rates are factors that affect the general prices of gold all over the world. Gold fails to pay interest in the same way a savings account or treasury bonds would. However, the current gold prices have often reflected a decline or increase in the interest rates (Lubienski Jameson 2016). When the interest rates hike up, the gold prices reduce since people will be selling their gold in a bid to free up funds to use for other investment opportunities. A decrease in the interest rates, however, results in an increase in gold prices. That is because people will want to save money and escape the effects of the high-interest rates. The gold price may increase later on because of the lower opportunity cost incurred in holding gold over other investments. Wealth protection is also a factor that affects the gold prices over the years. In the cases that result in economic uncertainty, investors will opt to invest in gold because of its value that is long lasting. According to Feiler (2006), gold is a metal that is unique because of its ability to withstand natures force of depreciation. That means that its depreciation is extremely low resulting in an enduring value. Thus, Gold is always a haven for investors during challenging economic times such as the economic recession of 2000. When the gold is in plenty, investors will purchase the gold to sell it when the prices are high. These investments reduce the supply of gold explaining the increase between December and January (see Appendix 1). Gold has been a hedge against trying economic times where gold prices are forced up. It has been a hedge for investors against deflation, inflation, and currency devaluation within an economy insulating investors. Thanks to its enduring value, invest ors will not feel the pinch of the economic falls.

A Work Community Problem of Communications

Question: Describe about a Report for A Work Community for the Problem of Communications. Answer: Identification of Challenges Faced by the Community Communication Problem: The problem in communication is one of the major problems that may hamper the functioning of an organization very deeply. An organization cannot grow and sustain in the long-run if it do not have an effective communication framework for communication of its daily functioning. The hindrance to communication in this case might be due to diversity of people which creates a language barrier and another issue that has been affecting the organization is prioritization of the personal issues at workplace (Baker and Warren 2015). Disputes: Prioritization of personal issues instead of having a common goal at workplace has been hampering the organization. The employees have the mentality of being jealous of fellow employees success as well as a consistent argument between the employees and their superiors which is due to excessive demands made by the superiors. Lack of Interest in Job: The excessive demands made by the superiors might give rise to lack of interest and dissatisfaction among the employees which may further give rise to under-performance by the employees due to the feeling of hopelessness against a particular task. Such situation creates a feeling in the mind of an individual that his/her skills do not match the requirement of the current job (Beehr 2014). Lack of Growth Opportunities: Lack of opportunities of promotion and growth added with growth and dissatisfaction and underperformance creates a feeling in the mind of an employee that he/she does not belong in the organization or he/she may deserve much better than the existing job profile. Solution to the Challenges and Goals Identified Effective Communication Model: The organization should develop an effective communication model to ensure smooth flow of communication in both upward and downward direction to have clarity of goals and objectives (Gordon 2015). Delegation of Authority and Responsibility: Each and every individuals authority and responsibility towards a particular work should be well defined and it should also mention the reporting head and extent of control the employee and the reporting head possess. Cordial Relation: The higher management should engage themselves in employees engagement programs. Doing this would help in create a better understanding of each other and will further reduce the friction between the employees and the superiors and would further improve the work environment. Equal Employment and Growth Opportunity: The management should set a code of conduct which would aim at non-discrimination at workplace and promote equal employment and growth opportunity. This would create a feeling among the employees that their talent is being valued. Democratic Leadership: The organization should encourage the employees to participate in the decision making process so that the employees may share their creative ideas and suggestion towards the improvement of the work environment. This would help in team building and enhanced organizational performance (Hendriks and Karsten 2014). Rational Needs of Work Communitys Mission and Values Clarity of Task and its Magnitude and Control: The organization should clearly define the task assigned to each individual and the degree to which they have to work and the controlling authority. Further, the organization should clearly state that no additional work should be assigned to the individual beyond the defined task and nobody should shoulder the task of their fellow workers tasks. Ethical Code of Conduct: The organization should establish a set of ethical code of conduct that defines the dos and donts within the organization. In case, any such codes are breached by the employees, they would be penalized for the misconduct. This would further help in reducing discrimination at workplace. Team Work: The management should engage the employees in various collective works to enhance their relationship and further improve communication. Doing such things would help in team building and improve the work culture and work environment. Employee Engagement Program: The employees from various departments should be encouraged to participate in fun sessions such as indoor sports, quizzes, excursions and many other activities. This would give a boost to their learning experience and help in team building. Feedback Mechanism: The management should devise a feedback mechanism to deal with deal with the problems and complaints from the employees. It would further be helpful for the management to understand the attitude of the employees towards the management. Sort of Knowledge Included to Establish Positive Power Relationship Appreciate Mutual Responsibilities and Anticipations: The management and the employees should appreciate and respect each others responsibilities and expectations. The employees should collectively work towards the achievement of organizational objectives and the management should meet the needs and demands of its employees. Analytical Thinking: The management should critically analyze various patterns across different situation and should identify critical issues under various circumstances (org 2016). Diplomatic Sensitivity: The management should have the ability to understand precisely the partially uttered thoughts or unspoken words, emotions and sentiments of others (Robles 2012). Negotiation: The management should always work towards a win-win situation. The management should have a clear understanding of the employees needs and respond to their needs accordingly. Confidence Building: Giving certain degree of independence to the employees would help the management in building the confidence of the employees. Celebrating the success of the employees and appreciating their contribution will further help in team building. Ethical Considerations Breach of Codes of Conduct: The breach of codes of conduct should be treated as a serious misconduct and must be dealt with in a reasonable manner. For example, if an employee is suspected in an act of racial discrimination or sexual harassment, then the employee should be punished for such offence (Leipziger 2015). Favoritism: The employer must not favor any particular employee with respect to bonuses or promotions by neglecting much more deserving and eligible employees. Such conducts are highly unethical at workplace and should be avoided on highest priority. Termination of Employee: The employer should not terminate an employee without prior notice. In case, the employer wishes to terminate an employee, the employee should be served with prior notice for minimum one or two months duration.

Advancements essays

Advancements essays Some of the advancements made in technology during the 1790s started off when the industry could not be stimulated overnight, because it required technology and the willingness of businessmen to invest time and capital for the long term. In 1788, the Pennsylvania Society for the encouragement of Manufactures and the useful arts introduced spinning jennies to their textile factory in Philadelphia. The jennies threatened to displace home spinners by producing cheaper yarn and thread. Another brand new technology that appeared was in 1790, Samuel Slater brought a new phase in American cloth production by building a textile mill in Pawtucket, Rhode Island, using water power to run the sinning machines. No satisfactory power loom existed, so Slaters mill performed only the first two steps of cloth production (preparing the cloth fibers for spinning, and spinning the thread.) He then used the putting-out system of distributing the thread to families, who produced the cloth at home. One more person who made an impact on the advancement of technology in the 1790s was Oliver Evans. He apprenticed as a wagon maker and became intrigued with machines. Evans heard that the Scottish inventor James Watt improved the steam engine a few years earlier. Evans began building his own model but for lack of money, thirty years passed before he actually installed a high pressure steam engine in his gypsum fertilizer factory in Philadelphia. This was the first such application of steam power to an industrial setting. Evans also developed the idea of automating mills. He devised water powered machinery for large grist mills that allowed one worker instead of three to supervise all the steps of producing flour. ...

Was European War inevitable in 1939 essays

Was European War inevitable in 1939 essays Was European War inevitable in 1939? In order to answer that question, one must consider the causes of the war and the circumstances that led to the tremendous success of the Nationalist-Socialist party in the first place. Also, had Hitler planned a European War or at least considered it? Facts are that after the treaty of Versailles Germany was left with the sole war guilt, with hardly any military forces and with a great loss of territory in Eastern Europe. In the public mind the harsh terms of the treaty of Versailles and the hard economics of the Great Depression seem to be two standard explanations. For almost a decade Germany was excluded from the international community. It did not join the League of Nations until 1926 or participate in the Olympics until 1928. The German inflation was devastating due to reckless wartime borrowing and fiscally disastrous post-war expenditures. Long-term unemployment was affecting blue-collar workers as well as white-collar workers, men, women and children were malnourished and many lost their confidence in the government. Between 1928 and 1932 suicide rates increased 14 percent for men, 19 percent for women . But not only had the economic troubles supported Hitlers rise, as inflation is far too facile an explanation . These factors, however, are the foundation on which building up a dictatorship was enabled. Was the European War inevitable? Had Hitler shown more modesty concerning his imperial goals and less eagerness for war in his politics, of course the war could have been prevented. If Great Britain had not pursued its appeasement policy and the United States of America had acted less isolationistic it could have been prevented too, or at least brought to a halt at a very early stage. The problem with these assumptions is that they are unhistorical by their nature, as Hitler would not have been himself without his longing for expansion, Great Britain without its appeasement s...

Marriage & Family Essay Example | Topics and Well Written Essays - 500 words

Marriage & Family - Essay Example By the 19th century, it relaxed its ruling, accepting public cohabitation as sufficient excuse for the validity of a marriage. However, later in that century, the US again took an active role in controlling who was allowed to marry who, with certain populations prohibited from marrying. Marriage licences were requirements in the provision of certain federal benefits and privileges for legal dependents. For example, in distributing benefits to employees’ children such as medical insurance, the employees should first present marriage licenses as proof that their children were legally their own. The same goes for inheriting properties from partners. Spouses should be able to present a marriage license in order to claim inheritance from their deceased husbands/ wives. That meant that illegitimate children did not have a claim to their parents’ resources simply because they were borne out of wedlock. Nowadays, due to strong advocacy for children’s rights, a marriage l icense no longer has the power to strip â€Å"illegitimate† spouses and children from claiming their rights to an inheritance. This way, the government accedes to the reality that everyone should be given what is due them with or without the proof of a marriage license. Coontz’ claims that people need the state’s permission to marry may be easily interpreted as the state having authority over who a citizen should marry. In a sense, there is value in that, as it serves as protection for individuals who are not aware that the person they are marrying may already be married, hence, leaving him or her to be a second priority or an illegitimate spouse. One should be ensured that his or her marriage is valid or legal under the law to be protected of his or her marital rights. Being licitly married means being permitted by society, and not forbidden. It is possible to have a valid but not licit marriage. One example is a marriage between a legally married black

An analysis of how 'management via accounting' can be applied to keep Essay

An analysis of how 'management via accounting' can be applied to keep fuel costs as low as possible at a low-cost airline, w - Essay Example This management essay is going to provide complete solutions and management measure for airline fuel management. These solutions cover fuel forecasting and planning, procurement, inventory and logistic management, contract management, and accounting and tax management. As a result, finance and purchase teams acquire a complete overview of airline inventory and obligation when they hedge and purchase fuel. Airline companies’ accounting management can automate and reduce fuel costs by processing of both financial derivatives and physical fuel purchases used in hedging. Therefore, the accounting department should come up with aggregated financial-physical fuel view positions and cost risk exposure (Calder, 2013:9). In fuel planning and budgeting, the accounting department must conduct an analysis of â€Å"what-if† situations such as changes in the type of aircraft used, introduction of new airports and routes, and forward cost curves. In addition, the accounts department m ust be able to report on actual fuel costs versus forecasted fuel costs to enable it calculate the airlines hedged fuel plan (Calder, 2013:9). Airline accounts management can effectively curl fuel use and get investments directly to the company’s bottom line through operating efficiently. ... lancing method ensure an favorable centre of gravity for all airplanes, the airport entrance planning is considered to ensure low fuel burn on the entrance grounds, and ensure there are daily operations improvement to recover from trouble shooting activities hence limiting burning of wasted fuel (Centre for Aviation, 2013). Currently, all airlines’ accounting departments must ensure that they have Fuel management information system, which is imperative to monitor fuel expenses and assist the accountants in coming up with effective solutions to minimize fuel costs. This is because airline fuel cost has become the biggest cost ranging between 25% and 50% of annual airline expenditure in all airlines across the world. Airline calculations indicate that one dollar rise in fuel cost is equivalent to 1.6 billion dollars expenses of an entire airline company. It is highly important for airline accounting department to develop effective fuel management software such as FuelPlus Softwa re (Calder, 2013:9). This efficient fuel expense and management software in the accounting department can bring massive positive effect on the progressive running of an airline operation and cause a direct effect on the airlines profitability, sustainability, and competitiveness (Channel 4 Dispatches, 2013). As reported by Centre for Aviation (CAPA) recently, the financial optimism is now becoming the main cause of higher fuel prices. Whilst in the old days, Fuel management system was seen as primarily a method of bringing commercial advantages, it is currently becoming an important element of an airline expense management toolkit. Fuel management is not just monitoring operational information, but also a widespread enterprise that involves all departments in the airport. The accounting
