Likely Effects Of Biofuels On Biodiversity An Environmental Sciences Essay Example

Likely Effects Of Biofuels On Biodiversity An Environmental Sciences Essay 1st coevals biofuels, the feedstocks are besides used as nutrient harvests and are chiefly used to bring forth biodiesel and bioethanol. These biofuels are straight produced and processed easy from the biofuel harvests or workss such as rapeseed, sunflower, sugar cane, maize etc. The 2nd coevals biofuels are generated from works lignocellulosic stuff. Bioethanol is generated by treating the lignocellulosic works stuff. Many perennial grasses, poplar, willow, forestry, agricultural waste merchandises etc are besides used to bring forth this 2nd coevals biofuels. The 3rd coevals biofuels are produced from algae which might non vie with nutrient harvests, doing it really feasible and more promising to be used. But the 2nd coevals and largely the 3rd coevals is non yet commercially feasible as the engineering is good advance and it is still undergoing development ( Biemans et al. , 2008 ) . This essay will be looking at the likely effects or impact of biofuels on biodiversity viz. the impact on home ground, impact on C segregation, impact on H2O quality and measure, impact of increased chemical usage, and impact of forestry and agricultural waste on biodiversity. This essay will besides briefly expression at a instance survey of biofuel impact in Netherlands. 2.

Biofuels can positively impact as a sustainable renewable beginning of energy, depending on its production technique, and can besides hold a negative impact, depending on the sustainability of its development. Bioefuel has a positive potency for cleaner fuels, and greater possibility for economic growing for rural communities and for husbandmans ( Pimentel and Patzek, 2007 ) . The major impact of biofuel on biodiversity is land-use alteration ( Koh, 2007 ) , and in state of affairs where biofuel will supply major part of planetary energy, this will countervail the possible extenuation of clime alteration due to decrease in green house gas emanation, by infringing extra lands to bring forth biofuel. Biofuel feedstocks picks, cultivation patterns, and the type of land that it is grown on, will find the positive or negative impact on biodiversity ( UNEP, 2008 ) . Impact on Habitat Crops grown in deforested country or degraded lands with decreased dirt cultivated land and agricultural inputs to supply feedstock for biofuel production could potentially impact biodiversity positively by reconstructing home ground and ecosystem map ( Cook and Beyea, 2000 ) . Turning perennial species for biofuel feedstocks besides have positive biodiversity impact than one-year monoculture planting, as some works or harvest rotary motion for biofuel feedstock can be good for some works species, butterfly, birds and some beings etc ( Cook and Beyea, 2000 ) . The most important cause for negative biodiversity impact globally is Habitat loss ( MEA, 2005 ) , and this could happen as a consequence of biofuel feedstocks production replacing other land utilizations, making negative impact on biodiversity. The addition in feedstock production could be affected indirectly taking to extension usage of land, this is seen in the instance where addition in maize monetary values for illustration in US has lead to husbandmans exchanging more land area of land from other harvest land usage to the cultivation of more maize ( Pimentel et al. , 2009 ) or direct extensions of cultivated countries which further additions habitat loss. For illustration, forested countries, peatlands, grasslands and wetland can be encroached for biofuel feedstock production. This can be seen in South-East Asia, where addition in demand for palm oil for the production of biodiesel has lead to a monolithic and extended deforestation, seting force per unit area on designated preservation countries ( Koh, 2007 ) . Besides in Brazil, demands for addition in the production of soy bean and sugar cane for biofuel has lead to monolithic loss of biodiversity in Cerrado and the Amazon rain forest ( Costa et al. , 2007 ) . Impact on Carbon Sequestration Land-use alteration due to biofuel feedstock harvest can besides act upon C dioxide emanation ( Searchinger et al. , 2008 ) . For illustration feedstock plantation for bioenergy on debauched land could increase the segregation of C, extenuating the planetary heating impact due to climate alteration ( Tilman et al. , 2006 ) . However, where big root of the perennial feedstock species for biofuel still remains in the dirt after crop, the sum of C in the dirt might be increased as a consequence of excess C being released from the roots to the dirt. The usage of sustainable agricultural patterns and high diverseness harvest rotary motion systems on debauched land can besides increase C segregation as a consequence of increasing dirt organic affair ( Tilman et al. , 2006 ) . Similarly, biofuels generated from waste and residues merchandises could hold no negative important impact on biodiversity and clime alteration as land usage alteration is non required for the production of the feedstock ( Searchinger et al. , 2008 ) . Biofuel feedstock plantation established on C rich dirt or forested land will greatly negate and out weigh the cleaner fuel from biofuel generated utilizing sustainable production by let go ofing monolithic nursery gases breathing as a consequence of land-use alteration and feedstock production. Procedures affecting drainage of peatlands, wetlands and glade of lands by fire for biofuel feedstock plantation can be destructive with respect to air quality and nursery gas emanations ( Righelato and Spracklen, 2007 ) . For illustration in south-east Asia, due to high demand in palm oil production, peatlands has besides been drained to run into the mark and as a consequence, it has been estimated that up to 100 metric tons of carbon-dioxide are releases in a twelvemonth per hectare and firing the peatlands doubles or three-base hits this value ( Righelato and Spracklen, 2007 ) , negatively impacting both below-ground and above biodiversity. In south-east Asia, United States and Brazil, it has been found through surveies that change overing peatlands, rain forests and grasslands for the plantation of crop-based biofuel feedstocks ( 1st coevals feedstocks ) table.1, creates carbon debt by bring forthing carbon-dioxide 17- 420 times more than the nursery gas one-year decreases derived by replacing dodo fuel usage with biofuels ( Fargione et al, 2008 ) . Water Quality and Quantity Impact Bioenergy harvest productions besides have impacts on H2O quality and handiness. Surveies have shown that biofuel feedstock production most particularly harvest feedstocks or first coevals biofuel feedstocks ( table.1 ) impact H2O resources negatively ( Berndes, 2002 ) . For illustration biofuel harvests like sugar cane, oil thenar, maize etc requires big sum of H2O for its productiveness and other biofuel feedstock harvests with greater water-use productiveness such as coconut and sugar Beta vulgaris can set force per unit area on the H2O tabular array ( Shepard, 2006 ) . There are besides instances of terrible H2O pollution, destructing aquatic life due to increases cultivation and production of biofuel feedstock. In 2007, the planetary nature fund named the Pantanal in Brazil the A ; acirc ; ˆ?threatened lake of the twelvemonth 2007 A ; acirc ; ˆA? due to H2O run outing from soya bean Fieldss, cultivated at the catchments of this lake as a consequence of increased demand and cultivation of biofuel feedstock ( Global Nature Fund, 2007 ) In Malaysia every bit good, Palm Oil Mill Effluent ( POME ) , residue of biofuel processing from palm oil is the major pollutant discharge into the Malayan rivers ( Ahmad et al. , 2006 ) . On the positive note, some of the biofuel feedstock harvests might be used in one of the bioremediation methods or phyto-remediation of contaminated H2O undertakings ( Berndes, 2002 ) . Increase Chemical use Impact on Biodiversity Expansion of lands for the production of biofuel feedstocks with homogenous cropping has lead to the increased usage of chemical applications like pesticides to command plague and besides most particularly more fertilisers to increase the dirt food and feedstock outputs has resulted in the increased emanation of N from dirt which is the major emanation beginning of azotic oxide universe broad ( MEA, 2005 ) . This azotic oxide has really high planetary heating potencies greater than that of carbon-dioxide. The addition usage of fertiliser, if sustainable patterns are non maintained to forestall leaching and eutrophicating foods emanation, can ensue in the increased eutrophication of aquatic and tellurian ecosystem and thereby ensuing to loss of biodiversity ( MEA, 2005 ) . Consequently, utilizing trees and perennial or 2nd coevals biofuel feedstock harvests ( table.1 ) , reduces the application of agrochemicals and as a consequence impacts the environment and biodiversity positively. Invasive Speciess Impact There is besides concern for invasive species debut to the ecosystem due to biofuel feedstock production ( Raghu et al, 2006 ) . Some of the 2nd coevals biofuel feedstock productions such as woody species and grasses ( table.1 ) have invasive species traits which include long canopy period, rapid growing and high H2O usage productiveness. It is feared that these biofuel feedstock harvests if introduced will non merely occupy but will besides displace some autochthonal species ensuing in lessening or loss of biodiversity ( Ragh et al, 2006 ) . For illustration in United States, biofuel feedstock harvests such as Johnson grass ( Sorghum halepense ) , Reed canary grass ( Phalaris arundinacea ) and Giant reed ( Arundo donax ) are already known to be invasive. Impact of Forestry and Agricultural Waste Feedstock on Biodiversity Waste is the 2nd chief beginning of 2nd coevals biofuel feedstock ( table.1 ) . Woody waste feedstock coevals can be harvested straight from forest or sawing Millss. Low C segregation and large-scale biodiversity losingss in woods is due to the remotion of deceasing and dead trees from the wood, as many woodland species live and feed on these waste ( Paul and Ernsting, 2007 ) . For illustration nonvascular plants, Fungis, invertebrates, lichens, beetling etc provender and live on forest dead forests depending on the dead wood volume assortment and grades of decomposition nowadays ( Jonsson et al. , 2005 ; Jonsell et al. , 2007 ) . Dead wood facilitates tremendous assortment of arthropods which attracts higher degrees of many species such as birds. Extraction and glade of this waste will diminish the home grounds of these species and might emphasize the productiveness of the wood. Similarly, remotion of the forestry waste merchandises for biofuel production can impact biodiversity positively by cut downing the hazard of forest fires. The impact of agricultural waste on biodiversity either positive or negative depends on the home ground they are generated from and the waste merchandise. Grass film editings remotion helps protect the profusion of species aided by unfastened home grounds and besides semi-natural grasslands are conserved from natural sequence. Removal of agricultural waste besides prevents the grass land from losing its aesthetic values and assorted ecosystems. Removal of grass or works litters or waste helps diminish the dirt food or organic affair and this enhances the profusion of species in diverse grassland home grounds ( Hansson and Fogelfors, 2000 ) . Consequently, remotion of agricultural waste for illustration straw, leftover from barley and wheat, which is used to increase the dirt organic affair can impact biodiversity negatively as dirt beings will be reduced and this might connote in the addition usage of nitrate fertilisers which has inauspicious consequence or impact on the fresh water and land ecosystem and besides on biodiversity every bit good ( Paul and Ernsting, 2007 ) . 3. Case Study: impact of biofuel production from wood french friess on biodiversity in Netherlands. The Son Heathland and the New Heathland are nature modesty countries in Netherlands with several pools, heathlands and forest dunes covering about 600 hectares ( Biemans et al. , 2008 ) . The municipality of these heathlands uses waste merchandises from these heathlands to bring forth biofuels in order to protect and conserve the heathland ecosystem from turning into a wood ( Biemans et al. , 2008 ) . The heathland ecosystem and its species profusion are sustained by guaranting care of unfastened infinite, as the heathland ecosystem might be taken over by forest if trees were non cut and cleared and used for the processing and coevals of biofuel. Not droping and cutting the trees might do a negative impact on biodiversity as rare species found in the heathland might free their home ground and the necessary ecosystem services needed for their endurances. Similarly, cutting the trees around the heathland ecosystem helps in the natural regeneration of the trees which provides chances for the safety of animate beings and workss. Normally, forestry waste is non removed in some ecosystem to conserve specific species and the ecosystem, but in these sites the Son Heathland and the New Heathland, it is removed for the production of biofuel, which helps to heighten and conserve the heathland ecosystem thereby impacting biodiversity both negatively and positively. 4. Decision The potency for biofuel to function as an energy security to protect and replace dodo fuel due to uninterrupted depletion of the dodo fuel minerals resource and besides its possible to extenuate green house gasses is great. But if sustainable direction ( e.g. for land usage and feedstock picks ) , policies and criterions are non set and implemented for the production of biofuels or bioenergy, the unsustainable practise in the production will do serious negative impact on biodiversity by destructing assorted ecosystem and home grounds. Besides societal impacts can non be ignored every bit good, as biofuel production might and will vie with nutrient harvests production in future, if attention is non taken to sustainable balance its production and will thereby impact the multitudes.

Most people need to find food at a reasonably affo Essays

Most people need to find food at a reasonably affo Essays Most people need to find food at a reasonably affordable price and Kroger offers it. HEB store falls behind in this arena because even though HEB offers food items, they aren't as cheap as Kroger. Walmart sells what the people need at an affordable price which brings in more customers. Walmart sells various name brand items in toys, hygiene, food, electronics and clothing. HEB focuses more on quality of food products even though the products are better quality they do slightly cost more. As far as arrangement both stores have like junk food down each aisle or canned goods and all the organic/healthy things on the outskirts. While Randall's is more expensive than both because most of the food there isn't processed. Also, compared to all three stores the customers in Randall's and the environment is more peaceful. Approximately around 50% of the products were produced in the US the rest is imported from other countries. Imports comprise an increasing share of food consumed by Americans, much of which cannot be produced domestically due to climate conditions and crop seasonality. Further, some imported foods cost less to produce abroad than their domestically grown counterparts. In conclusion consumers prefer an increasingly wider selection of food products, such as tropical fruits and vegetables, premium coffee, and a greater variety of cheese, grain products, and preserved meats so that why most of our products are from foreign places because the US cant' produce it all. Agriculture and fisheries are highly dependent on the climate. Increases in temperature and carbon dioxide can increase some crop yields in some places. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety. For example, while I was shopping at Walmart in the produce aisle I noticed the tomato had spots around it so maybe the climate change may have affected the growing season of it. Significant improvements in transport technology took place since Von Thunen designed his agricultural land use model. For instance, with rail systems, it became much more cost effective to transport agricultural commodities over longer distances. Further, refrigeration enabled to move perishable products cost-effectively over long distances. Since most of the American agricultural landscape was established in the late 19th and early 20th century, agricultural land use was much less constrained by transport costs. Large scale agricultural regions thus emerged where agricultural land use was influence by distance from major markets and by local geographical conditions. When comparing the prices between the stores I noticed the only difference between prices ranges from 30 cents to $2.00. Yes, the price difference is significant to those that have a very limited income and don't really care about quality of a product. But for those who care about the quality and where they buy their food products from than the price difference isn't as significant to them. My advice to those that have a limited income is get what you can afford and that you're not limited to only discount stores so get what you prefer but also afford at the same time.

Emerging risks from climate change Research Proposal

Emerging risks from climate change - Research Proposal Example The key characteristics of climate change are the following ones: ‘uncertainty, complexity and potential for dangerous consequences’ (Jubb, 2010, p.1). In a report published by the Parliament, House of Commons (Britain) it is noted that ‘the timescales of climate change is long and its extent is uncertain’ (Yeo, 2010, p. 110). In practice, it seems that high-emitting countries are likely to face more challenges when trying to control the effects of climate change – Saudi Arabia belongs in this category (Harman 2011). At the same time, not all countries worldwide are adequately prepared for handling emergencies related to climate change; in a relevant report of Ernst & Young it is noted that Saudi Arabia has not, yet, established rules governing the reduction of gas across the country (Ernst & Young 2009). Moreover, Saudi Arabia is among the countries that have not yet ratified the Stockholm Convention on Persistent Organic Pollutants (The Canadian Pre ss, 2011).

The interview will have behavioral structured questions that will aim to assess the knowledge and skills of a particular candidate to test his or her compatibility with the roles and responsibilities required by the position. In addition the structured interview will focus on evaluating the behavioral aspect of a candidate’s personality beyond eligibility. This will enable the identification of a candidate that is fit for the position. The structured interview will be used to assess an individual’s candidacy by keeping the job requirements as a standard. As such it will be designed such that the questions will relate to specific job requirements. The questions will also allow deeper behavioral aspects of a candidate to surface in different mock situations required as part of a general manager at a theatre. The job analysis will be an underlying factor shaping the interview questions. More specifically the interview questions will be structured and inquire about an individual’s background in arts, theatre, and business. It will also aim to test the knowledge of an individual in key business concepts such as cash budgeting, forecasting, etcetera, where the candidate will have to demonstrate his or her knowledge and skills. Additionally, some scenario-based questions will be asked that assess the candidate’s behavior and actions given particular hypothetical questions (Bell, 1999; Arizona Human R esources, 2013). Past experience will also be asked to be described and/or demonstrated through specific examples. The recruitment will be conducted

Partial fulfilment of the Requirement Essay Example for Free

Partial fulfilment of the Requirement Essay THE PROBLEM AND ITS BACKGROUND Introduction Nowadays, we are experiencing diseases which is caused by insects like mosquito. To name some are Dengue, Hemorrhagic Fever, and Malaria wherein if not treated early it can cause death. Mosquitoes are all around the corner of our environment. They are not that big but can cut off life. To control the mosquitoes, different mosquito repellent are made and the laboratory chemicals are effective but they are quite expensive and not environmental friendly. Chemicals also are harmful to our health; it may cause a sudden death in case of improper handling. In the rural barangays there are common herbal plants used by rural folks in exterminating harmful insects like mosquitoes. And so the research was conceptualized to detect the insecticidal effect of Alliums cepa (Onion) and Allium sativum (Garlic) on mosquitoes and make a mosquito repellent out of onion and garlic, a not expensive repellent that everyone especially the poor ones can afford. Garlic and Onion contains allicin that is capable of repelling mosquitoes and allicin is inimical to mosquitoes. Another reason is garlic and onion has also a strong odour that overwhelms the mosquito’s sense of smell and prevents from finding their prey (us). Statement of the Problem This study will be conducted to examine if there is an insecticidal effect in the extract of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes and to make a repellent out of it that will be guided with the following questions: * Is there an insecticidal effect in the extract of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes? * Is the extract of Allium cepa (Onion) and Allium sativum (Garlic) effective as a mosquito repellent? Objectives Generally, the study aims to determine if there is an insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. Specifically, the study aims to know if the extract of Allium cepa (Onion) and Allium sativum (Garlic) is effective on repelling mosquitoes. Significance of the Study The study can help in repelling mosquitoes for it will examine the insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. This study will be helpful to people especially those living with many mosquitoes around them for it will be easy for them to make it and it’s safe. And the repellent will be an environmental friendly. It can also help lessen the dengue and malaria outbreak. Scope and Limitations The study will be conducted from November 2012 to December 2012. It will be conducted on a cool warm dry room. The effectiveness of this repellent will be applicable to the place where the experiment will be conducted. Hypothesis There will be no insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. The extract of Allium cepa (Onion) and Allium sativum will not be effective as a mosquito repellent. REVIEW OF RELATED LITERATURE Recently, our country is suffering from different kinds of outbreak just like dengue and malaria outbreak and this is caused by mosquitoes. Mosquitoes are around us, they are small but they can cause death if you are bitten with it. To control these insects some of us buy expensive insecticide though it is effective it is also harmful. Harmful to our health because it contain chemicals that if mishandled can cause to death. It’s not also environmental friendly. Herbal repellent are commonly used by rural barangays where the people find it difficult for them to buy commercially available insecticides for mosquitoes, and so the researcher was conceptualize to examine if there is an insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes and to make a repellent that is effective to repell mosquitoes, a non-toxic repellent, an environmental friendly and a cheaper mosquito repellent. Onion and Garlic has an allicin that is capable of repelling mosquitoes and other insects. The allicin which is released by Allium cepa (Onion) and Allium sativum (Garlic) are inimical by mosquitoes. The another reason why Garlic and Onion can repell mosquitoes is their strong smell that overwhelms the mosquito’s and prevent them from finding their prey (us). Onion Onion is the common name for herbaceous, cold season plant Allium cepa, which is characterized by an edible, rounded bulb composed of concentric, fleshy, tightly packed, and an enlarged leaf basses. Onion is also the name of this edible bulb, which is commercially valuable and known for its pungent oil that departs a strong taste. Onion are found in a large number of recipes and preparations spanning almost the totality of the world’s cultures. The whole plant is edible and is used as food in some form or other. They are now available in fresh, frozen, canned, caramelized, pickled, powdered, chopped and dehydrated formed. Onion can be used, usually chopped our sliced, in almost every type of food, including cooked foods and fresh salads and as spicy garnish. In European cultures they are rarely eaten on their own, but usually act as accompaniment to the main course. Depending on the variety, an onion can be sharp, spicy, tangy, pungent mild or sweet. Onion contains allicin that is capable of repelling mosquitoes. Onions can also repel mosquitoes because of its strong odour and its spicy flavour which mosquitoes hate. Commonly a red onion is used by repelling mosquitoes. Garlic garlic is plant grown for its sharp-tasting bulb, which is used to season foods. Some plants related to garlic including the onion also have strong flavour. The garlic bulb consists of parts called cloves. The cloves may be eaten or used for planting. A brittle papery covering called a tunic grows around each cloves] and around the whole bulb. There are several important components of garlic that have been identified, and many more that have not. Alliin is an odourless sulphur-containing chemical derived from the amino acid cysteine. When garlic bulbs are crushed, alliin is converted into another compound called allicin. Allicin appears to be one of the primary active compounds that gives garlic its characteristic odor and many of its healing benefits. However, allicin is not absorbed effectively by the human body. To combat this problem, aged garlic is fermented to break allicin down to usable compounds. These compounds are water-soluble sulphur compounds (S-ally cysteine and others) and an amount of oil-soluble sulphur compounds. Alicia is a powerful compound of garlic. If the garlic releases an illicit it is inimical to mosquitoes. They have therefore evolved to avoid garlic, another reason why garlic can repel mosquitoes is that the strong smell of garlic overwhelms the mosquito’s sense of smell and prevents them from finding their prey (us). RESEARCH METHODOLOGY Materials Alliums cape (Onion) and Alliums stadium (Garlic) will be the main components of the repellent and will be the source of illicit. Cayenne pepper will be added to onion and garlic to make it spicier. Liquid dish soap will be needed to make the repellent fragrant. In getting the extract of Onion and Garlic, blender will be used. A sprayer is also needed wherein the repellent will be placed. Test Organism Fifty mosquitoes will be collected and must be distributed equally to five containers for the five set-ups. Mosquitoes will serve as the test organism. Test Procedure In making the repellent, chop into small pieces the onion and garlic without peeling. Place the chopped onions and garlic at the blender with the cayenne pepper. Then place a 250 mol amount of water. Blend on a slow speed to a milky consistency. After blending place the extract of onion and garlic pin a empty bottle sprayer. Wait an hour to add 50mL liquid dish soap for the extract will be odorous. Then shake well. In determining the insecticidal effect, there will be five set up. The first repellent will have 100g of onion and garlic. Second set up will have 100g of onion and 70 g of garlic. Third setup will have 70g of onion and 100g of garlic. The fourth set-up will have 100g of onion and 100g of garlic and liquid dish soap will not be added. And the fifth set-up will be a commercial insecticide to determine is what is more effective. One set-up will be sprayed at the one container with mosquitoes and the researcher will record how long will all the mosquitoes die and how many mosquito will die in one 30 sec, 1 min, 1 min and 30 sec, and 2 min. The other set-ups will also undergo this procedure. RESEARCH PLAN Student’s Name| Kamille Joy P.

Ethics Of The Hellenistic World Essay -- essays research papers fc

In comparing the ethical theories of the Epicureans, Aristotle, and the Stoics it’s found that they possess three separate ideas. These ideas are different in their individual beliefs; yet attempt to accomplish the same goals of creating an inner peace and sense of well being in their followers. Generally these three disciplines had distinctly separate ideas on how to set about accomplishing these goals; the Epicureans felt that the pursuit of pleasure was the correct path to enlightenment, while the Stoics had the idea that the conformation to strict laws regarding virtue was the proper path, and as for Aristotle, he held the middle ground in this debate of the minds, feeling that moderation was the key to complete happiness. Epicurus' ethics was a form of egoistic hedonism, meaning that the only thing essentially valuable is one's own pleasure. Anything else that has value is valuable merely as a means to securing pleasure for oneself. Epicurus associated this theory to a refined and individual view of the nature of pleasure, which lead him to recommend a virtuous, moderately frugal life as the best means to securing pleasure. His ethical theories find a foundation in the Aristotelian commonplace that the highest good is what is valued for its own sake, and not for the sake of anything else. Epicurus also agreed with Aristotle that happiness is the highest good. However, he disagreed with Aristotle by identifying happiness with pleasure. Epicurus gave two reasons for this. The main reason was that pleasure is the only thing that people do having value just for its own sake; that is, Epicurus' ethical hedonism is based upon his psychological hedonism. Everything we do, he claimed, we do for the sake of ul timately gaining pleasure for ourselves. This is supposedly confirmed by observing the obvious behavior of infants, who instinctively pursue pleasure and shun pain. The truth in this is also found in the behavior of adults, but in adults it is more difficult to see that this truth, since they have much more complicated beliefs about what will bring them pleasure. This hedonism was widely denounced in the ancient world as undermining traditional morality. "The trouble with Epicureanism is its assumption that the self is a bundle of natural appetites and passions, and that the end of life is their gratification. Experience shows that such a policy consi... ...le relates that the healthy exercise of virtuous function in a well-rounded life exploring personal interests and friendships is the cause of which happiness is the unavoidable and fitting effect. In other words, if you pursue the cause you will create the effect, but if you pursue only the effect circumventing the cause, you will miss both effect and cause entirely. â€Å"Aristotle rejects the Epicurean principle of pleasure; because, though a proof that isolated tendencies are satisfied, it is no adequate criterion of the satisfaction of the self as a whole. He rejects the Stoic principle of conformity to law; because it fails to recognize the supreme worth of individuality†(Hyde, 175). Even after this comparison it is difficult to contend which of these three theories would be a valid philosophy today. As they all have their seemingly strong points, there are still intrinsic weaknesses that would not hold up under the scrutiny of contemporary philosophers. Bibliography Hardie, W.F.R.

Top Down Leadership vs Bottom Up Leadership

Top down Leadership versus Bottom up Leadership Top down leadership has in many ways been the cultural gnome in terms of leadership styles for probably the longest time in history Likert termed it Exploitive authoritative. â€Å"In this style, the leader has a low concern for people and uses such methods as threats and other fear-based methods to achieve conformance. Communication is almost entirely downwards and the psychologically distant concerns of people are ignored. (Likert, 1969) Top down leadership has had a deep impact and so much intertwined with human culture that it is deemed to be simply the natural form of leadership. There are many other forms of leadership styles being nurtured so as to adapt with cultural changes and views on leadership roles, not to say they are any lesser but top down and bottom up were at both extremes of the leadership spectrum hence choosing to focus on the two. The structure of most organizations is based on an autocratic hierarchy that is based on the notion that the ‘workers’ need to be very closely supervised by those in ‘management’. In the distant past there may have been some truth to this assertion, however, in today’s world it is becoming increasingly spurious. Yet after a whole heap of culture change initiatives carried out in many organizations very little positive change has occurred. The reason is clear to see as the hierarchy is naturally committed to retaining the status quo between the roles of those called ‘bosses’ from those labeled the ‘workers’. (para11, Jaap, June 2011) Bottom-up leadership however â€Å"occurs when employees become innovative and questioning, making suggestions and pushing boundaries. â€Å"Thought leadership† is similar, although it is more about championing new ideas than managing people or helping a group achieve a goal. However, in b oth cases, the leadership can be directed upward, and it ends once senior managers accept the proposed ideas. † (Ki-Young & Mi-Jin 2008 summer p. 9) The concept of bottom up leadership requires a person to think outside of the box because it challenges mainstream beliefs and ideologies as regards to leadership roles. There is an oriental saying that states â€Å"cup would have to be poured out to allow room for more a filled†. Which implies putting aside of one’s wisdom so as to learn new material. Jaap characterization of a bottom up leader is that â€Å"An effective leader is considered to be someone who has the ability to share a compelling vision of a desirable outcome, create the environment in which a group of ndividuals work as a collaborative team focused on turning the vision into a reality. † (Par5 Jaap 2008) For most people the bottom up concept is relatively not applied as it really should due to the fact that people who are in leadership roles tend to have insecurities if more flexibility were to be offered to employees. The leaders deem that people would in actuality develop some form of negligence to those that are in position of authority. Take for instance the anti government protests that developed all across the Middle East, these protests are as a result of people who are frustrated by the top down leadership style being carried out by their leaders. Leadership as it was in these Arab nations was flowing only on a downstream when it came to the issue of communication, for the people’s concerns were being met by brutal force which included jail term and death in some cases to any person that seemed to offer an alternative to the top down leadership that was in place. The western world has a strong belief for equal rights for all and most importantly the right for all to live a fulfilled life and it is quite apparent as the Arabs began questioning for these same rights their leaders who had their heads buried under the sand were under the assumption that their usual scare tactics would quench the flames of revolution. However, these were not the usual times in Arab nations, the revolutionary flames burn on rampantly towards the leaders who have in all actuality failed to lead their nations due to the fact that they led as though they had eternity to rule, which was the greatest mistake to have done. They failed to observe the change in tide as the world around them continued to evolve, more and more people getting connected via internet. Social media had set up stage for people to voice their concerns as to what directions their leaders were getting them to travel, their lack of empathy and lost track of reality only looking for more ways and means to enlarge their bank accounts, assets and investments at the cost of people. Had the approach been taken on a bottom up approach the outcome would definitely have been different due to the fact they would have had empathy and understanding for a bottom up leader is as follows. The leader is part of the team and accepts that on occasions other members of the team may in fact take on the leadership role because they have the necessary capabilities to deal with particular situations more so than the nominated leader. The working environment is based on trust and respect for each other and the language is about our â€Å"leader, colleagues, team, accountability, achievement, success, and celebration† rather than â€Å"boss, staff, levels, roles, responsibility, remuneration, and appraisal†. There is a constant sharing of information between the team members and sincere dialogue about issues that may be contentious because colleagues have different perspectives and expectations. By transparently dialoguing these and all other issues the best solution is more likely to emerge because the team is able to make the tough call when necessary. They tend to avoid meetings and discussions based on consensus as they know from experience that this process tend to produce a solution driven by the lowest common denominator and frequently not what is needed by the organization. Par7 Jaap 2008) Not wanting to seem all too pessimistic towards top down leadership, there are certain areas such as the military organizations or police force where top down leadership is and strongly believe will continue to be employed in such areas to the unforeseeable future because the whole system is heavily based upon order. The military organizations in America are applaud able and should be exemplary for the rest of the world military to emulate, not to be deemed as a war fanatics’ but rather as an organization that understands what entails protecting its citizens. Leadership however is what directs them to war, peace, rescue missions etc for that is typical for those who are disciplined to follow top down leadership. â€Å"The whole system tends to absorb its people in focusing on rules and procedures designed to keep everyone in their appropriate place doing exactly what each tribe dictates its members should be doing. Most organizational language is about reinforcing the master/servant or parent/child relationship that appears to be an essential part of the military type of hierarchy â€Å"(par4 Jaap May 2008). Keeping this in mind we also have to understand that the discipline they have did not just appear out of nowhere, they had to undergo rigorous training in order to be transformed into a command structured person. Rivers stated in his research There is little question that one of the chief causes of the great prevalence of nervous disorders in the war is that vast numbers of men have been called upon to endure hardships and dangers of unprecedented severity with a quite insufficient training. There is equally little doubt that the special nature of the duties involved in trench warfare has taken a large part in determining the great frequency of neurosis. (Rivers 1920) An argument that a critic would say is that Rivers wrote the book almost a century back, technological advancements have been made in leaps and bounds to outweigh nervous disorders and the two to three month training period is very much sufficient. In the article The emotional effects of war T, Stan states â€Å"Some veterans of past wars have recovered from their traumatic experience with the right care, but what we need to ask ourselves is how we can protect them from mental trauma before they are even sent to fight, as opposed to treating their symptoms once the deep psychological damage has already been done. â€Å" (Stan. ) Unfortunately the fact of the matter remains to date that there are soldiers that suffer psychologically as a result of doing what their work requires, which is top down leadership at its raw definition. These military examples indicate that as much as human beings have made top down form of leadership a reality it can be extremely costly because war is not quite human nature otherwise there would not be reports of psychological issues as a result of following orders to the bitter end â€Å"The emotional effects of war on soldiers very often hinders their future achievements too as they find it impossible to imagine or plan. † (Stan. By majorly focusing on the psychological effects of extreme top down leadership one can deduce that as a result of exposing human natural emotions through such experiences has daunting and drastic effect that the individual would have to bear on a personal basis that even further affect the social aspect of life and family life. It takes training the human qualities to this image of a soldier to serve further implying how top down leadership does not quite just come naturally but is instilled on a person. The approach towards bottom up leadership simply put emphasis on doing what human beings do best which are being social creatures that we are. Human beings generally have more tendencies to show concern for just about anyone in distress disregarding all other factors such as race, nationality, etc. bottom up leadership works to build on the basis of establishing social relationship as its core foundations because people are really the most important asset any institution or organization could possibly have. Focusing on who people are as human beings develop empathy on the part of a leader and people tend to give more effort when they feel people actually do care and understand where they are coming from. â€Å"The emotional intelligent professional is a master of building relationships, which provide the foundation for developing the influence required to make things happen. To become a master yourself you must develop your emotional intelligence and learn. (Wall, 2008, p37) In life it has become apparent that common sense in most cases is not quite common for human beings have invested great time and effort towards scientific research as to how better efficient leadership could be achieved and the human factor was just but an element on the production line where efficiency of workers has and always been based on individual output with little or no attention to the needs of the laborer. For an organization to be firmly established to withstand the tides of change, greater emphasis should be made in the areas of relationship development as being the major component in the structural base. â€Å"As we facilitate organizational change efforts for client companies, we find it helpful to use a few nautical metaphors to remind them that they can’t control the winds or seas of change but they can adjust their sails† (Sipe & Frick 2009, p142). With the development of social media a much broader avenue has been made when it comes to unifying people bent on same beliefs and course of actions. The Middle East crisis is the emancipation of a top down form of governance at its wits end where fear tactics no longer played the factor, for people were united in common bond for social change as they deemed injustice was being played against their God given rights to freedom. The protesters dropped all they were doing, businesses, government; financial institutions and so on were all brought to a halt because the nation’s work force saw that it could no longer be business as usual when their leaders have no real concern for their needs. Now you may ask â€Å"what has this to do with culture change in organizations†. My response would be to say â€Å"quite a lot† as the reasons the various regimes fight to retain the status quo is a mirror image of what goes on in organizations. They may not use armed weapons but they do tend to make significant use of traditional, psychological and physical methods to quell any imminent revolt by employees. Jaap, T (par2 June 2011). Creativity is an essential part of the human nature that fosters new ideals, inventions and venture to greater heights by virtue of imagining beyond the sum of one’s present circumstances. In order to facilitate these qualities individuals have to have a form of freedom that makes it conducive for free flow of knowledge and ideas based on the fact that they no longer see the work they are doing as work but develop a sense of ownership and passion in the roles they have to perform in the organization. Most organizational leaders would highly appreciate workers that bring enthusiastic views and effort to work for it energizes the whole team. Not only would that develop a healthy working atmosphere but the productivity also will definitely be increased exponentially because everyone would understand that they are valued and all their inputs play a vital role in the operational process. Many leaders are more than likely going to argue that bottom up leadership could only cause chaos in the work place rather than productivity as a result of everyone having self expression as to how they look at life in the organization. The leaders in most cases forget an important concept that they themselves are called to serve. Rather than leading in a group top down leaders would rather lead ahead of the group which implies egotistic approach on the whole leadership process for the individual leader seeks to gain attention as being the alpha dog of the group. Bottom up leadership however is focused on developing team spirit in the organization where people unite to tackle the task at hand with clear objectives of getting the job done right and credit is made to the team as a whole. Not only is bottom up leadership a healthy form of leadership style it will in most cases increase employee retention hence ensuring that the organization has committed people on the team which does go a long way in comparison of trying to build passion in people who are disgruntled by leaders that only understand my way or the highway form of mindset The importance of team development could not be understated, they are what hold organizations together, by professionalizing conflicts in actuality if done well fosters healthy working relationships. Conflicts should not be taken personally and working roles need to be well defined so that those involved have good understanding of their responsibilities as pertaining to the task at hand. As being part of the team one has to be actively involved in the decision making process by adding input so as to take the participatory approach. While in a team it is also good to remember that when there happens to be problems in the organization it is very likely that 85% percent is as a result of system failure and 15% people A main force behind my thinking is the conviction that a management style from the bottom up, instead of top down is more effective. Main reason for this is that by being stimulating and facilitating people are better equipped to perform their tasks: higher motivation, less stressed and more able to absorb complexity†¦. I am convinced that if this style of management is in your brain, you have a more tolerating, productive and positive mind set, and one that is based upon trust instead of fear. I am convinced that educating around the globe about this style (instead of the old top-down directive leadership style) will have an amazing impact on more than just how businesses are run. It is about a better human-human interaction. (Par7 De Baar 2008) References Likert, R. (1967). The human organization: Its management and value, New York: McGraw-Hill Jaap, T (June 2011).
