Symptoms And Symptoms Of Anxiety Disorders - 1665 Words

Anxiety Disorders With having so many natural explanations for the potential development of a mood disorder, do anxiety disorders also have natural components? The study conducted by Balik, et al. (2014) didn’t only contain findings of PMS and mood disorders; they also found evidence relating PMS to anxiety disorders. They reported that â€Å"more than half of women with PMS have a history of anxiety† (p 373). Does this mean that PMS is indicative of an anxiety disorder or is it the other way around? Regardless of which comes first, having one may also mean that woman has the other. If a woman has PMS they may also have anxiety and vice versa, if a woman has anxiety they may also suffer from PMS. Additionally, Gagua, et al. (2013) had similar†¦show more content†¦1584). Essentially, because identical twins share 100% of their genes regarding a single trait, it makes sense they would also share 100% of their genes regarding the covariation of two or more traits. They also found a higher neuroticism score for women, which indicates a higher likelihood of GAD. Environmental, or Nurture With such clean implications of natural influences towards mood disorders such as depression, and anxiety disorders, genetics (and biology) clearly play a large role in the development of disorders. Theoretically, environmental factors would play just as important a role in the development of these disorders, as all genetics really do is create a predisposition towards the disorder and doesn’t necessarily cause it, after all, plenty of psychologists (and many other scientists) would argue that humans are merely a product of their environment. Mood Disorders Similar to natural factors, the first type of disorder to examine is mood disorders. Taking the results that Balik, et al. (2014) and Gagua, et al. (2013) found that dysmenorrhea and PMS show an increased risk of a depressive disorder, this is not necessarily a biological implication. While the PMS (or the dysmenorrhea) is, itself biological, the ensuing mood disorder is not necessarily also

Evolution Of Human Resource Management Essay - 974 Words

Evolution of Human Resource Management Administrative Functions The objective of the Human Resource Department is to design management systems to ensure human talent is maximized to effectively and efficiently achieve organizational goals. HR has seven functions that are intertwined. These functions are global, environmental, cultural geographic, political, social, legal, economic, and technological. Human resource management has the potential to drastically impact the success and effectiveness of an organization. Human Resources has heavily focused on recordkeeping and paperwork. It has often been considered a clerical and low-level administrative department. In most organizations, Human Resources is looked upon as the employee mediator in the organization. They tend to be the voice of the employee, building company morale and putting out fires involving crisis management. The problems they deal with are both employee work-related and not work-related. HR strives to ensure fair treatment for all employees. They work with varying departments throughout the organization in order to create and implement necessary programs and policies. HR works with equal employment opportunity and other laws, to ensure compliance. They work to fill current job openings by processing applications, interviewing, and training.

The Elasticity of Oil Production and Consumption

Table of Contents Introduction Oil Demand Oil Supply Peak oil production Oil Price elasticity of supply Conclusion Works Cited Introduction Oil is one of the leading good consumed in the world. It is a commodity that is mostly traded at the global scene. Majority of countries in the world depend on this good for servicing their industries and for manufacturing. Oil is the major source of energy in the world. The case of fluctuation in prices of oil is a very common global phenomenon, with the rise in prices bringing a blame game.Advertising We will write a custom research paper sample on The Elasticity of Oil Production and Consumption specifically for you for only $16.05 $11/page Learn More When oil prices rise a lot of friction is witnessed with most governments blaming the international oil cartels, the citizens blaming the governments for not taking steps to regulate the prices of oil while other economists stand to argue that market forces are t he determining factors and hence no need for blaming one another. The effects of changing prices of oil have far reaching impacts to the global economy (Riley, para. 1). This paper explores the market forces in the oil market and how their elasticity affects the supply and demand of oil. Oil Demand The efficiency of energy, for instance oil can be established by measuring the energy quantity used per unit of the output attained. This is also referred to as energy intensity. It can also be established by comparing the increase in the rate of energy consumption and the rate of gross national product growth which roughly equals to the demand elasticity for energy (Amuzegar and Fonds monetaire international, p. 87). It is a fact that energy demands is at greater length unrelated to the price of energy that is in the short-run. However, in the long-run, resilient changes in prices of energy have a significant effect on the demand for the commodity (Natal, p.26) There exists a strong corr elation between oil and the rate at which the world economy grows because of the essentiality of oil as an input in industry. As the economy develops, demand for oil in the economy rises. For instance, China’s economy has grown very fast, and this growth has been accompanied by a rapid growth of the output of the country in sectors that consume a lot of energy. This has necessitated an upsurge in the demand for oil in the economy of China. This is referred to as cyclical demand (Riley, para. 3). The demand for oil can be also affected by the prices of oil substitute products, for instance the relative price of gas in the market. If more reliable and relatively cheap oil substitutes are developed, that is on a long term basis, the demand is most likely to shift away from oil to its substitutes. However, this is still at a wishful level. The changing seasons affect the demand for oil.Advertising Looking for research paper on business economics? Let's see if we can help yo u! Get your first paper with 15% OFF Learn More During the winter season in the United States and Canada, more energy is needed to run the heating systems both in houses and at the places of work thus the demand for oil rises (Riley, para. 4). There always exists a speculative demand for crude oil that is purchasers always do hope for an increase in oil prices in the world market. This has made many oil businessmen and corporations to invest in buying future oil contracts (Riley, para. 6). Oil Supply When the supply of oil is discussed, a crosscut line should be made between short and long term supply of oil to the global market. The curve indicating short run supply is drawn basing on a given technological state of production and the use of capital inputs in a fixed basis. In the daily supply of oil, a short-run limit is inevitable, but as production nears capacity limits, the short-run oil supply become elastic (Riley, para. 8). The short-run of oil supply is affected by a number of factors. Profit motives of both OPEC non–OPEC countries have a big impact on the supply of crude oil. OPEC accounts for approximately 40 percent of oil supply in the world while other countries account for the other percentage. It thus has a central influence in determination of prices of oil – that is when members act together to take charge of production and put to balance the market forces in the world market. The cartel sets quotas on the amount of crude oil they are to produce with the reason to stabilize oil price at a certain targeted level (Riley, para. 9). On the other hand, the long run supply of crude oil in the market is also influenced by certain factors. These are low oil reserves that results from depletion of the oil resources due to an ever increasing demand for the commodity. Exploration affects the supply of oil by the virtue of the investment in exploring new oil zones. Change in the technology of extracting oil affects the extraction co st and the profit levels of extraction and refining thus impacting on the supply of the commodity (Riley, para. 10). Most classical economic theorists on argue that a rise in demand for a good or service results in the rise in the price for that good. They further add that when prices of a commodity rise, more businessmen are attracted to invest in the production of the commodity. This leads to a surplus in production, thus resulting in a shrink in price as competition between manufacturers continue. However, these economics failed to consider their argument as it should be applied on a depleting good like oil, minerals and natural gas. The production and consumption of these commodities is relatively inelastic when other factors for example politics, cultural factors and environmental destruction are held constant. For these commodities the shifts in investment however huge the shift may be has no likelihood to lead to a correspondence rise in supply (Cooke, para.3).Advertising We will write a custom research paper sample on The Elasticity of Oil Production and Consumption specifically for you for only $16.05 $11/page Learn More The global oil market has been very inelastic to an extent that huge rises in upstream investment do not produce contemporaneous rise in supply anymore. Assuming that other factors remain constant, it takes a very long time to establish an oil field. Moreover, we have limited ability to bring newer production online thus. The limit is caused by political objectives of nations and the cultural constraints. An example is countries like Venezuela, Iraq or Nigeria where cultural economics has worked in any potential elasticity to decline due to local restrictions (Cooke, para.3). The efficiency of energy can be established by measuring the energy quantity used per unit of the output attained. This is also referred to as energy intensity. It can also be established by comparing the increase rate in energy cons umption and the rate of gross national product growth which roughly equals to the demand elasticity for energy (Amuzegar and Fonds monetaire international, p. 87). It is a fact that energy demand is unrelated to the price of energy that is, in the short-run. However, in the long-run, resilient changes in prices of energy have a significant effect on the demand for the commodity (Natal, p.26) Peak oil production After the mid 2008, the aggregate demand for oil declined due to very high prices. This is the time when the world recession was beginning. The oil price later collapsed. The demand for oil recovered in 2009. The sharp rise in price of oil followed and was accompanied by a sharp rise in commodities and services that utilize oil in its production (McGreal, p. 120). Oil Price elasticity of supply Price elasticity is the measure of the level to which production can rise to satisfy the rising demand. The increase in production is related to a rise in prices. If the supply of oil is inelastic, increased production is followed by a sharp rise in prices. It is presumed that the ceiling price of oil that we experience today is linked to the recovering demand that has come after the recession rising against a tighter supply. The sharpest recession was experienced more than seventy years ago (Natal, p. 27).Advertising Looking for research paper on business economics? Let's see if we can help you!

Prices of oil have more often than not generated big debates and causing friction in some countries. The demand for oil keeps increasing. The demand and supply of oil is determined by numerous factors though there are some dominant factors that affect oil production and consumption. The elasticity of oil production and consumption is centrally impacted by the oil cartel that controls the production of oil in the world.

The Eruption of Mount Tambora in 1815

The Eruption of Mount Tambora in 1815 The tremendous eruption of Mount Tambora in April 1815 was the most powerful volcanic eruption of the 19th century. The eruption and the tsunamis it triggered killed tens of thousands of people. The magnitude of the explosion itself is difficult to fathom. It has been estimated that Mount Tambora stood approximately 12,000 feet tall before the 1815 eruption when the top third of the mountain was completely obliterated. Adding to the disasters massive scale, the huge amount of dust blasted into the upper atmosphere by the Tambora eruption contributed to a bizarre and highly destructive weather event the following year. The year 1816 became known as ​the year without a summer. The disaster on the remote island of Sumbawa in the Indian Ocean has been overshadowed by the eruption of the volcano at Krakatoa decades later, partly because the news of Krakatoa traveled quickly via telegraph. Accounts of the Tambora eruption were considerably rarer, yet some vivid ones do exist. An administrator of the East India Company, Sir Thomas Stamford Bingley Raffles, who was serving as governor of Java at the time, published a striking account of the disaster based on written reports he had collected from English traders and military personnel. Beginnings of the Mount Tambora Disaster The island of Sumbawa, home to Mount Tambora, is located in present-day Indonesia. When the island was first discovered by Europeans, the mountain was thought to be an extinct volcano. However, about three years before the 1815 eruption, the mountain seemed to come to life. Rumblings were felt, and a dark smoky cloud appeared atop the summit. On April 5, 1815, the volcano began to erupt. British traders and explorers heard the sound and at first thought it to be the firing of cannon. There was a fear that a sea battle was being fought nearby. The Massive Eruption of Mount Tambora On the evening of April 10, 1815, the eruptions intensified, and a massive major eruption began to blow the volcano apart. Viewed from a settlement about 15 miles to the east, it seemed that three columns of flames shot into the sky. According to a witness on an island about 10 miles to the south, the entire mountain appeared to turn into liquid fire. Stones of pumice more than six inches in diameter began to rain down on neighboring islands. Violent winds propelled by the eruptions struck settlements like ​hurricanes, and some reports claimed that the wind and sound-triggered small earthquakes. Tsunamis emanating from the island of Tambora destroyed settlements on other islands, killing tens of thousands of people. Investigations by modern-day archaeologists have determined that an island culture on Sumbawa was completely wiped out by the Mount Tambora eruption. Written Reports of Mount Tamboras Eruption As the eruption of Mount Tambora occurred before communication by telegraph, accounts of the cataclysm were slow to reach Europe and North America. The British governor of Java, Sir Thomas Stamford Bingley Raffles, who was learning an enormous amount about the native inhabitants of the local islands while writing his 1817 book History of Java, collected accounts of the eruption. Raffles began his account of the Mount Tambora eruption by noting the confusion about the source of the initial sounds: The first explosions were heard on this Island in the evening of the 5th of April, they were noticed in every quarter, and continued at intervals until the following day. The noise was in the first instance almost universally attributed to distant cannon; so much so, that a detachment of troops were marched from Djocjocarta [a nearby province] in the expectation that a neighboring post was attacked. And along the coast boats were in two instances dispatched in quest of a supposed ship in distress. After the initial explosion was heard, Raffles said it was supposed that the eruption was no greater than other volcanic eruptions in that region. But he noted that on the evening of April 10 extremely loud explosions were heard and large amounts of dust began to fall from the sky. Other employees of the East India Company in the region were directed by Raffles to submit reports about the aftermath of the eruption. The accounts are chilling. One letter submitted to Raffles describes how, on the morning of April 12, 1815, no sunlight was visible at 9 a.m. on a nearby island. The sun had been entirely obscured by volcanic dust in the atmosphere. A letter from an Englishman on the island of Sumanap described how, on the afternoon of April 11, 1815, by four oclock it was necessary to light candles. It remained dark until the next afternoon. About two weeks after the eruption, a British officer sent to deliver rice to the island of Sumbawa made an inspection of the island. He reported seeing numerous corpses and widespread destruction. Local inhabitants were becoming ill, and many had already died of hunger. A local ruler, the Rajah of Saugar, gave his account of the cataclysm to British officer Lieutenant Owen Phillips. He described three columns of flames arising from the mountain when it erupted on April 10, 1815. Apparently describing the lava flow, the Rajah said the mountain started to appear like a body of liquid fire, extending itself in every direction. The Rajah also described the effect of the wind unleashed by the eruption: Between nine and ten p.m. ashes began to fall, and soon after a violent whirlwind ensued, which blew down nearly every house in the village of Saugar, carrying the tops and light parts along with it. I n the part of Saugar adjoining [Mount Tambora] its effects were much more violent, tearing up by the roots the largest trees and carrying them into the air together with men, houses, cattle, and whatever else came within its influence. This will account for the immense number of floating trees seen at sea. The sea rose nearly twelve feet higher than it had ever been known to be before, and completely spoiled the only small spots of rice lands in Saugar, sweeping away houses and every thing within its reach. Worldwide Effects of the Mount Tambora Eruption Though it would not be apparent for more than a century, the eruption of Mount Tambora contributed to one of the worst weather-related disasters of the 19th century. The following year, 1816, became known as the Year Without a Summer. The dust particles blasted into the upper atmosphere from Mount Tambora were carried by air currents and spread across the world. By the fall of 1815, eerily colored sunsets were being observed in London. And the following year the weather patterns in Europe and North America changed drastically. While the winter of 1815 and 1816 was fairly ordinary, the spring of 1816 turned odd. Temperatures did not rise as expected, and very cold temperatures persisted in some places well into the summer months. Widespread crop failures caused hunger and even famine in some places. The eruption of Mount Tambora thus may have caused widespread casualties on the opposite side of the world.

Accidents in which chlorine has spilled in factories have also been unknowingly mixed with other chemicals. Undoubtedly, thousands of people have been in at risk for exposing to this reaction and have been evacuated to address the issue. The worst incident occurred in 2005, when the crash of 18 freight trains occurred, exposing chlorine gas to a whole community in which 9 people were killed and at least 1400 were exposed to this fatal combination. The worst part about chlorine gas is the fact that it even small exposures can cause choking and wheezing. In addition, it can burn the eyes, skin and throat. The gravity of this issue can be depicted here as Mary Anne Duncan, an epidemiologist at the federal Agency states, â€Å"Exposure to high levels of chlorine gas from a release can cause severe health effects, including death.† Researchers insist that these conditions lead to fatal heart disease and continue to rise at a shocking rate. Throughout history, Chlorine has been used to not only for killing purposes in war but also to infuse fear. The body has no control over the metabolic rate as an individual is exposed to it. The gloomy depiction painted here is exactly what occurs during these incidents. Chlorine had a high percentage with victims, 30.9 percent, second only to carbon monoxide, which had 41.7 percent with victims. Clearly, this is a threat that should be addressed. From my perspective, this clearly seems to be an issue that must be approached from a very serious manner. This will continue to be a hazardous agenda on the minds of the several residents who can seriously develop tragic medical conditions. Since chlorine is lethal, the government should try to enact some laws for companies that can safely handle these type of sensitive chemicals. Additionally, all residents should be well-aware of the dangers of
