Fascinating Facts Got this from one of my day by day joke messages. Thought it was fascinating enough to share : 111,111,111 x 111,111,111 = 12,345,678,987,654,321 In the event that a sculpture in the recreation center of an individual on a pony has both front legs noticeable all around, the individual passed on because of wounds got in fight; if the pony has each of the four legs on the ground, the individual kicked the bucket of common causes. No word in the English language rhymes with month, orange, silver, and purple. Factions of quite a while in the past that needed to dispose of their undesirable individuals without executing them use to torch their homes - subsequently the articulation "to get fired." Canada is an Indian word meaning "Big Village". There are two Visas for each individual in the United States. Just two individuals marked the Declaration of Independence on July fourth, John Hancock and Charles Thomson. The vast majority of the lay marked on August 2, yet the last signature wasn't included until 5 years after the fact. "I am." is the most brief total sentence in the English language. The term "the entire 9 yards" originated from WWII military pilots in the South Pacific. When equipping their planes on the ground, the .50 bore assault rifle ammunition belts estimated precisely 27 feet, before being stacked into the fuselage. In the event that the pilots terminated all their ammunition at an objective, it got "the entire 9 yards." The most well-known name on the planet is Mohammed. The word "samba" implies "to rub navels together." The universal phone dialing code for Antarctica is 672. The paste on Israeli postage stamps is affirmed legitimate. Mel Blanc (the voice of Bugs Bunny) was adversely affected by carrots. Until 1965, driving was done on the left-hand side on streets in Sweden. The transformation to right-hand was done on a weekday at 5pm. All traffic halted as individuals exchanged sides. This time and day were picked to forestall mishaps where drivers would have gotten up in the first part of the day and been too drowsy to even think about realizing that *this* was the day of the changeover. The absolute first bomb dropped by the Allies on Berlin during World War II slaughtered the main elephant in the Berlin Zoo. Dr. Seuss articulated "Seuss" to such an extent that it rhymed with "rejoice." In Casablanca, Humphrey Bogart never said "Play it again, Sam." Sherlock Holmes never said "Elementary, my dear Watson." A greater number of individuals are slaughtered every year by jackasses than kick the bucket in air crashes. The term, "It's all pointless fooling around until somebody loses an eye" is from Ancient Rome.

The Mythology Of The Iliad - 1277 Words
In The Iliad, the Olympian Gods were depicted as a group of individuals who were still completely vulnerable to mistake and harm despite their great power. Zeus was one, if not the biggest and most powerful God among all other Gods. Known as the King of the Gods, Zeus was a mighty, dominant, and seemingly supreme God, despite his tendency to show surprising silliness and sometimes, the lack of wisdom through his choices, especially when it came to love affairs, which eventually led to many problems that could have been prevented. Zeus, in The Iliad, Zeus is a representation of how ancient Gods were just normal humans equipped with a great degree of power and capabilities, but they have the tendency to show humanly behavior and mistakes. In the Homerââ¬â¢s Iliad, Gods are very susceptible to human desire. At some point, Gods can act more ââ¬Å"humanâ⬠than actual humans would act. They would think, act, speak, and do other things just like a human being. The only thing that s eems to differ Gods and human is their immortality, power and authority over things. Compared to the gods found in Abrahamic religions, Greek Gods base their decisions and action without principle but feelings and their personal opinion. Greek God are known to be capricious, prone to arguments over insignificant things, showing a very close relationship with human behavior. These characteristics of Greek Gods are probably generated due to the lack of need to thrive and survive since they are immortal andShow MoreRelatedGreek Mythology And Mythology Of The Iliad, Oedipus Rex And Others1294 Words à |à 6 Pagesbeen shaped by mythology and religion.

Phylogenetic Classification Systems â⬠Free Samples for Students
Question: Discuss About the Phylogenetic Classification Systems? Answer: Introducation The earlier taxonomic and phylogenetic classification systems were based on morphology. As the science of microscopy developed and it became possible to study the cellular structure, classification of organisms was based on the differences in cell structure. With the advent of ability to sequence DNA and RNA, it became possible to compare the sequences. This led to the ability to distinguish between organisms on the basis of dissimilarities between the sequences. The three tax domains as per the current system of classification are eubacteria and archaeabacteria, both prokaryotic and the eukaryotes. Prokaryotes and eukaryotes were earlier differentiated on the basis of cellular morphology. The absence or presence of nucleus was the main structure that differentiated them. Carl Woese suggested that the classification should be based on the 16S rRNA or 18S rRNA sequences rather than on morphological differences (Woese, Kandler, Wheelis, 1990). The basis for earlier methods for classification was organism based, it was later based on cellular Management and is now based on differences at the molecular level. As a result phylogeny is now understood on a molecular basis rather than a phenotypic basis. The basis for description of eukaryotes appeared to be based on the shared complexity of cellular organisation. But the same was not true for prokaryotes, the differences amongst the organisms could not be phylogenetically described just because these cells did not contain a nucleus. This was revealed when it was discovered that the archaeabacteria are as different from bacteria as the y are different from the eukaryotes and thus three domains were proposed, namely, eubacteria, archaeabacteria and the eukaryotes. The archaeabacteria that were studied later are methanogenic, thermophilic and tolerant to high salt concentrations, conditions that were prevalent on earth in ancient times. All organisms have DNA and the genes are expressed through protein synthesis. Ribosomes are the sites for protein synthesis and rRNA molecules are components of ribosomes. The rRNA molecules are also encoded by DNA. Mutations have occurred in the rRNA genes during evolution. The reason why rRNA was suited to be the molecule of choice for molecular phylogeny was because it was present in all organisms and the mutations that occurred in the molecule were such that they allowed the formation of ribosomes. Any mutation that could have disrupted the formation of ribosomes was eliminated through natural selection. rRNA can be easily isolated in the laboratory and comparison of rRNA sequences from two organisms can help determine how closely (or distantly) they are related on an evolutionary time scale. The rRNA molecules fold into secondary and tertiary structures due to complementary base sequences. The tertiary structure of rRNA exhibits differences between eubacteria, archaebacteria and eukaryotes. The small subunit rRNA in the eubacteria is different from the archaebacteria and eukaryotes between bases 500 to 545 that form the bulge that protrudes from the stalk in the tertiary structure. It is 6 nucleotides long in the former while the bulge is made up of seven nucleotides in the latter, the compositions of the nucleotide stretches are also different in eubacteria. The region of small subunit rRNA in eukaryotes has a sequence between nucleotides 585 and 655 which is peculiar to the domain (Gutell, Weiser, Woese, Noller, 1985). The prokaryotes have a different but common structure in the corresponding region. The archaebacteria have a unique domain in their 16S rRNA between 180-197 positions and between 405 and 498 positions (Woese, Gutell, Gupta, Noller, 1983). A comparison of the three domains yields similarities between the eubacteria and the archaeabacteria but more similarities occur between the archaeans and the eukaryotes. The nuclear membrane and unit-membrane enclosed organelles are present in the eukaryotes but re absent among the two prokaryotic domains. The eubacteria have a peptidoglycan cell wall that is absent in the other two domains. Eubacteria have only one kind of RNA polymerase while archaebacteria and eukaryotes have several kinds of RNA polymerases that share structural homology (Huet, Schnabel, Sentenac, Zillig, 1983). During protein synthesis the initiator amino acid among the eubacteria is formyl-methionine, but methionine is the initiator amino acid in the other two domains. Both archaebacteria and eukaryotes have genes with introns but eubacteria have genes without introns. Antibiotics like streptomycin and chloramphenicol can only inhibit the eubacteria. DNA is packaged with the help of histone proteins in the eu karyotes, some archaeabacterial species but none of the eubacteria. The prokaryotes have circular chromosomes. Some species of archaeabacteria are thermophilic and can grow beyond the temperature of 100oC. Thus there are several similarities between the archaebacteria and eukaryotes (Reece, et al., 2014). In conclusion, the new system of taxonomic classification is based the differences between the rRNA and some gene sequences. The position of the archaeabacteria as a separate domain has been established based on their similarities with eukaryotes and the eubacteria. The similarities and mutations in the small subunit of rRNA have been extensively studied to establish the domains and form the basis for molecular phylog References Gutell, R.

The Euro Crisis and its Impact
Abstract The Euro crisis is an economic crisis that not only points at the weaknesses of economic integration, but also points at the consequences of poor economic policies at the state level. The aim of this paper is to synthesise literature on the causes, progression, and impacts of the Euro crisis on the European economy.Advertising We will write a custom coursework sample on The Euro Crisis and its Impact specifically for you for only $16.05 $11/page Learn More The literature shows that the Euro crisis is far from over. The European countries have to rethink about the economic integration strategies that can encourage prudent management of individual economies in the region to avoid such shocks. Introduction The Euro crisis was seen not only as a financial problem in the European Union countries, extending from the global financial crisis, but also as a real test of the essence of economic integration. The European Union has come out as a benchmark o f economic integration in the whole world. The rationale behind the terming of the European Union as a global benchmark when it comes to matters of economic cooperation and unity among states in the region is that it is the only economic union that has managed to realise the workability of a common currency. However, as mentioned in the opening sentence, the Euro crisis, whose genesis lies in the debt crises that mounted in a number of countries that form the monetary union, namely Greece, Spain, Ireland, and Italy, among others, resulted in the replication of the problem across the European Union. A substantial number of economic commentators term the Euro crisis as a problem that denoted the difficulty of integrating individual economies and dealing with economic pressures that come from the attributes of economic management in individual economies. The interesting thing about the crisis is that it serves as an example of how problematic economic integration can become because the faulty actions of other players could pose grave economic consequences requiring major economic decisions and adjustments by the individual states to solve the problem.Advertising Looking for coursework on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More This paper presents a review of literature on the Euro crisis and its impacts on Europe and the entire global economy. The paper contacts three main research databases, namely EBSCOHost, SIRS Researcher, and ProQuest. These three databases play a critical role in presenting sequential information regarding the moulding of the Euro crisis and the consequences of the Euro crisis in terms of economic policy development and the performance of the economy, more so on the affected economies. The selection of articles from EBSCOHost is based on topic search, where preference is given to different articles denoting diverse dimensions of research about the Euro crisis. Most of the articles derived from the SIRS Researcher database point at the fact that the Wall Street Journal receives more attention because most articles in this database are those published by the Wall Street Journal. This is aimed at producing data that is consistent concerning the development of the crisis as understood by the researchers who write for the Wall Street Journal. The articles selected from the ProQuest database depict information about the Euro crisis based on the external views about the effects of the crisis beyond the European Union borders. The genesis of the Euro crisis A substantial number of economic commentators agree with the observation that the Euro crisis, which is also referred to as the sovereign debt crisis, was brought about by the significant deficits in the balance of payments of individual countries due to unsustainable fiscal policies pursued by these countries over a substantial number of years. Higgins and Klitgaard (2014) argue that the Euro crisis beg un from the fiscal problem in Greece due to the accumulation of debt by Greece. Higgins and Klitgaard (2014) further note that Greece and other periphery economies in the European Union relied heavily on external capital. These countries needed the capital to finance housing booms and domestic consumption. The only option that seemed feasible to them was to borrow from other countries, given they could not afford to source the finances locally. Wood (2012) observes that the European countries, especially the countries in south Europe, failed to agree on a common framework on which they could opt for the Euro as a common currency.Advertising We will write a custom coursework sample on The Euro Crisis and its Impact specifically for you for only $16.05 $11/page Learn More At this point, Germany gets a fair share of the blame for failing to exercise a leading role and, instead, taking a fiscal strategy that plunged the other southern Europe economies into debt (Wood 2012). Milios and Sotiropoulos (2010) ascertain the essence of looking at the Euro crisis from the perspective of the cycles of capitalism in the Eurozone, rather than pointing fingers at the debt crisis in Greece. The real value of economic integration lies in the kind of strategies that are taken by countries forming the economic block to offset the deficits in the balance of payments. In this case, the crisis in the Eurozone is a problem that cannot be directed at one country, but the failure should also be associated with the other countries that had a chance to salvage the debt problem in the region. However, they failed to do so due to their own reasons. The high rate of indebtedness in Greece depicts not only the weakness of economic governance in Greece, but also the failure of Germany as a key player in the region to activate some steps that could salvage Greece and the entire region at large (Dinan 2012). Rosenthal (2010) further observes that the deficit limit that was set by the European Union was not only exceeded by Greece, but also other players in the European Union like France. The main concern here is that the European Union did not sanction France because of political malice. The rationale here is that France is a big brother in the European Union; that is why it is favoured even when it breaches the set standards of the EU monetary union (Rosenthal 2012). The figure below could serve as an indicator of the manipulation of the economies of the region by Germany due to the introduction of the Euro as a common currency in 2002.

Figure 1.0 denotes a significant rise in Germanyââ¬â¢s current account balance after the introduction of the Euro as a common currency in 2002. The non-existence of an exchange-rate buffer prior to the introduction of the Euro as a common currency led other weak economies in the region to lose their competitiveness as Germany took advantage of its manufacturing and export power to deny other countries the opportunity to thrive in the market. This indicates a kind of economic exploitation of other countries, a factor that necessitated the increase in the amount of foreign debt (Rosenthal 2012). Baimbridge, Burkitt and Whyman (2012) ascertained that the deflation that was later experienced in other countries in the Eurozone was as a result of the creation of a boom-bust cycle emanating from the implementation of a similar interest rate for all countries. As the most powerful economy in southern Europe, Germany could easily adjust its taxation regim e to compete at a fairly lower exchange rate. This could play a critical role in reducing the financial burden in other Eurozone countries. For more information about the comparative aspects of foreign current account balance in the European Union, see figure 1 and figure 2 in the appendix. Higgins and Klitgaard (2014) observed that dependence on borrowed money often results in its risks, particularly in situations where the countries from which the money is borrowed are no longer in an economic position to offer credit. Higgins and Klitgaard (2014) base this assumption on the issues of saving and investment at the domestic level. They note that reliance on borrowing and the failure to invest the money in economic segments that can spur local investment and savings, just as in the case of Greece and other countries in the European Union, often results in economic problems. A broader look at the Euro crisis by Wood (2012) reveals a number of causative factors. Among these factors are imprudent banks, errors in economic policy development and implementation, remote technocracy, lack of effective regulation, and turbo-capitalism. These factors are, in one way or another, linked to the mounting of the debts in individual countries across the European Union. However, Wood (2012) further observes that the Euro crisis is an economic crisis that cannot be only linked to the mounting debts in individual economies in Europe, but also a problem that can be understood by incorporating other attributes like history, sociological forces, and other elements of governance across Europe. In other words, Wood (2012) moves away from the dominant view supported by a substantial number of researchers, who synthesise the Euro crisis only based on the debt question while failing to open up to other forces that might have resulted in the worsened economic situation in Europe. Hall (2012) raises similar sentiments by noting that the Euro crisis presents a number of puzzles, as people seek for answers about the real causes of the crisis in what was earlier on applauded as a benchmark as far as economic integration in the world is concerned. Hall also paints the picture of how the two hemispheres in Europe seem divided over the crisis, where the northern European countries blame the south by pointing at the fiscal faults inherent in the economic policies of southern Europe governments. Hall presents an important statistic about the Euro crisis. Figure 1.1: Percentage growth of domestic demand in individual economies from 1999 ââ¬â 2009. Source: Hall (2012), p. 360. The figure indicates significant variations in demand for growth, which means that the countries with a high percentage of domestic demand were under pressure to develop and enforce growth-oriented reforms. As the country with the highest domestic demand, Greece had no other option that to be proactive in developing strategies that could help meet its skyrocketing domestic demand. Borrowing from th e other countries with limited domestic demand was necessary to meet the domestic demand in Greece (Hall 2012). Progression of the Euro crisis A deeper look at the Euro crisis shows that the crisis moved from the debt problem in individual economies to the subsequent currency war. Rosenthal (2012) observes that the crisis in the Eurozone is best reflected in the difficulties that transpired in the operation of the monetary union. The functioning of the union was threatened as it became apparent that the local currencies in individual economies were becoming weaker and the affected countries had little to do to limit the deficits in their balance of payments. A series of actions were taken as a way of seeking for a solution to the plummeting currency problem in the Eurozone. Among these actions were the numerous currency devaluations to strike a balance between supply and demand. The setting in of the monetary union created a tough situation for currency speculation in the region. Th e extreme downward adjustment in the exchange rate meant that a further downward adjustment of the exchange rate would not be achieved (Rosenthal 2012). Baimbridge, Burkitt and Whyman (2012) present another dimension to the Euro crisis, in which they focus on the creation of the Eurozone and the effects that come with its creation. Fiscal discipline is vital in the sustenance of a monetary union. The free-rider and spill-over effects as noted in the Euro crisis are perfect examples of the faults of fiscal policy in the management of a monetary union. Thus, Baimbridge, Burkitt and Whyman (2012) summarize the Euro crisis by pointing at the prevalence of a number of structural weaknesses in the Eurozone. It is the structural weaknesses in the European Union that resulted in the escalation of the debt crisis from Greece to other countries in the Eurozone. In their assessment of the mounting debt crisis in the Eurozone, Higgins and Klitgaard (2011) noted that the rates of borrowing in th e Eurozone rose amidst the introduction of the common currency and the inability of individual countries to finance their domestic expenditures. Higgins and Klitgaard (2011) also note the creation of an economic cycle of dependency in the European Union, where a number of countries in the region were left to become dependent on borrowed money. Higgins and Klitgaard (2011) also acknowledge the countermeasures taken by the affected countries, most of which entail the consolidation measures. These measures are aimed at attaining a significant reduction in fiscal deficits in the required set standard of below 3 per cent. The measures to bring down the fiscal policies that are being implemented now could have been put in place earlier to prevent these countries from entering into debt crises, such as the one that culminated into the Euro crisis (Higgins Klitgaard 2011). A focus on the impacts of the Euro crisis based on the functioning of markets in the European Union and other countrie s that fall outside the European monetary and economic unions by Melander (2011) shows the heightened effects of the crisis beyond the assumptions made by the European Union. This is notable in the observation made by Zuckerman (2011) and Francis (2012), who ascertain the essence of the countries beyond the European region to develop and implement economic measures that can cushion them from the crisis. Malander (2011) paints the picture of the distress in countries where the Greek financial institutions were operating prior to the Euro crisis through the entire build-up of the crisis as shown in the figure below. Figure 1.2: Impacts of the distress in Greece of the periphery sovereigns. Source: Malander (2011, p. 356). The common denominator of the figure is that the weaknesses portrayed in the economic systems of Greece were replicated in the financial institutions from Greece. The deepening of the distress in Greece over the years resulted in the deepening of the distress in oth er economies that had close links with Greece through the operation of Greek institutions in these countries. It is also apparent that the exposure of the Greek economy in line with the weaknesses in other economies like the Irish economy also acted as an aggravating factor for the Euro crisis (Malander 2011). The same can also be said about the mounting of the debt crisis in Ireland as indicated in the figure below. Figure 1.3: Distress in Western Europe countries following the distress in Ireland. Source: Malander (2011, p. 357). This expands on the reason why the Euro crisis comes is an intertwined economic problem that cannot not be sorted out easily by implementing unitary strategies. The approach taken by each individual country has a lot of effects on other countries in the European Union. Zuckerman (2011) reports about the currency defaults across the European Union as a result of the low lending rates by the European Central Bank to countries in the European Union. Most ba nks were left with no option because of the growth in the amount of unnegotiated currency defaults. There is no room for underestimation as the debt that has been accumulated by countries in the region, including Italy as the 8th largest economy in the world, is too huge. Italy is also ranked as a third largest bond market, but it remains unclear whether the $2.6 trillion sovereign debt accumulated by the country can be cleared any soon. Zuckerman (2011) justifies the worry of the United States by observing that most of the affected countries in Europe continue to come up with austerity programs. However, these programs are risks in themselves as they deepen the recession in most cases, thereby making it even harder for the affected countries to service the huge debts. The more these debts prevail, the more difficult it is to establish sustainable economic relations between the affected countries and other economies in the world. Also, the Euro as a common currency in the European U nion faces major challenges, especially from people who link the crisis to the introduction of the Euro as a common currency in the Eurozone (Zuckerman 2011). However, Brittan (2010) defends the Euro by observing that the Euro is not a problem per se. The problem in the Eurozone lies with the inconsistent and fragmented economic policies and strategies adopted by the countries in the Eurozone. Saving the Euro is the priority of the European Union. Nonetheless, a look at individual countries, especially the economic powerhouses in the European Union like Britain, France and Germany, shows that these countries are committed to saving their financial institutions like banks from the risks associated with the Euro crisis (Farrell Quiggin 2011). Farrell and Quiggin (2011) further note that some countries like Germany have gone as far as developing laws to help induce debt brakes. Other countries in the Eurozone, totalling to sixteen, also followed a similar road. However, most of the ef forts initiated by players in the Euro crisis are short-term, raising questions about the possibility of developing long-term economic measures to prevent a debt problem from occurring again in the future. Farrell and Quiggin (2011) see the short-term strategies as necessary for limiting expenditure and ensuring that the bond markets across the Eurozone calm down. After laying blame on Greece for the Euro crisis, most of the European countries agree that saving Greece is a key step in easing the economic pressure in the region. The budget crisis in Greece was a subject of most European leaders in the onset of the Euro crisis, more so when the countries in the region realized that the budget problem in Greece was not only a problem of Greece, but also a problem of all other countries in the region (Forelle, Walker Galloni 2010). Impacts of the Euro crisis and the lessons learnt Mà ¼nchau (2013) observed that the Euro crisis is an example of smouldering crises that are born out of t he lack of prudent systems of economic management in economic integration. Mà ¼nchau cites what he refers to as the inflexible fiscal rules and compliance procedures that impeded the creation of incentives. What happened is that the system of economic management that came immediately and after the introduction of a monetary union subjected the smaller economies in the region to tough economic measures, most of which could not be upheld by these states. The application of the principles of economic management like the no bailout principle enshrined in Article 125 of the European Union Treaty is a justification of how difficult it is to solve problems of insolvency in individual economies that form the European Union. Other cited difficulties include the ââ¬Å"no defaultâ⬠and ââ¬Å"no exitâ⬠principles, which limit the level at which liquidity support can be offered to European Union member countries in times of crises (Mà ¼nchau 2013). To this effect, Mà ¼nchau reiter ates the essence of intense coordination of policy, monetary, fiscal, national sovereignty, and regional and global policy to avoid a situation where the players in economic integration read from different pages. Melander (2011) is quite pessimistic about the application of the principles of economic liberalization by states in the quest of states to conform to economic integration. Melander uses Ireland, one of the countries that exhibited the problem of mounting debt in the progression of the Euro crisis, by noting the fact that Ireland was applauded as a benchmark for flexibility and liberalization in the realms of economic integration. The situation later changed when Ireland later plunged into a debt amidst the mounting economic pressure in the Eurozone. The progression of the crisis resulted in a situation where the benchmark countries in terms of economic liberalization like Ireland and the worst performing economies in the region like Greece ending up in the same capsizing b oat (Melander 2011). The other issue that comes out in Melanderââ¬â¢s (2011) analysis of the Euro crisis is the fact that economic networks are potentially harmful, irrespective of the minute nature of the economic problems that occur in an individual country. Together, Greece and Ireland do not even amount to 5 percent of the GDP of the Eurozone, yet the debt crisis in the two countries posed a threat to the entire European Union economy. Capital flow in trade and finance between member states in an economic union is an issue that warrants attention by individual states because individual states remain with the responsibility of supporting its institutions in times of economic downturn. However, a look at the response to the debt crisis in Greek and other countries proved the inability of governments to support their financial institutions. Consequently, these financial institutions were rendered helpless in terms of boosting the domestic financial status of the economy of count ries where they base their operations (Melander 2011). Xafa (2010) explores the unavoidable questions about the role of the global financial institutions like the International Monetary Fund (IMF) in cushioning countries from the effects of the Euro crisis. The International Monetary Fund served as a key institution in raising alarm about the global financial crisis. Nonetheless, such an alarm could not easily work with the Euro crisis. The Euro crisis required more than policy advice, especially for the countries that were already facing the economic effects of a huge foreign debt now that these emerging European economies could not access the externally funded credit from other countries. Irrespective of this, Xafa applauds the International Monetary Fund for its proactive steps of continuous surveillance of the global economy. Failures that resulted in the worsening of the economic situation in the European Union are linked to the rigid commitments of individual countries, which make them stiff when it comes to matters of economic support and adjustment for the common good of other states (Xafa 2010). Besides the issue of economic and financial regulation by international bodies like the International Monetary Fund is the issue of willingness of countries to go to the deeper ends in salvaging a monetary union. Karras (2011) contends with the fact that the introduction of the Euro as a common currency triggered the credit problem in the Eurozone, thus necessitating credit pressures across the Eurozone. However, Karras also agrees with the findings made by a substantial number of economic researchers pointing at the fact that the economic decisions taken by individual countries at the early stages of the Euro crisis were highly disintegrated and could not promote a common solution. The observation here can be linked to the opinions raised by a substantial number of economic commentators, who argue that the Euro crisis would result in losers and winners. Heisb ourg (2012) indicates that the winners and losers in the economic turmoil depended on the economic and political paths pursued by individual countries. The Euro crisis is a lesson to countries in the European Union, most of which have had to review their strategic economic choices. An example given here is the reliance of Germany on exports and the difficulty to sustain exports when the destiny countries face severe economic problems that inhibit their potential to import goods from Germany (Heisbourg 2012). Since the beginning of the European sovereign debt crisis, the United States as one of the largest traders with the European Union has remained active in terms of making adjustments in its economy. Most, if not all the adjustments, are aimed at cushioning the country from the shrinks in trade and securing its financial system from fallout like the financial system of Europe (Francis 2012). In the real sense, a direct exposure of the United States markets to the crisis in the Eur opean Union has not been established. However, a substantial number of investors in the United States share the sentiment that the United Statesââ¬â¢ market is vulnerable to the crisis in the Eurozone, especially when long-term solutions do not come from the European countries (Heisbourg 2012). In his research about the export strength of Germany in the European Union amidst the crisis in the Eurozone, Foroohar (2011) found out that Germany export capacity depends on the internal economic strengths of a number of countries in the European Union, like Spain and Italy. The reason why Germany finds itself at the centre of the Euro crisis is that it depends on the Eurozone for approximately half of its net exports (Foroohar 2011). The financial woes in the Eurozone present a new basis on which the issue of regional economic integration should be reassessed. Walker and Galloni (2013) report on the thoughts raised about the benefits and risks associated with leaving and remaining in th e European Union for countries that have been severely affected by the Euro crisis. The opinion about leaving the Euro vary across Italy, where 74 per cent of the Italians feel that it is prudent for Italy to remain in the Euro while 20 per cent of Italians feel that leaving the Euro is an economic reprieve for Italy. However, most governments in the Eurozone remain consistent in support of the Euro, which makes Walker and Galloni (2013) to conclude that the Euro is meant to stay put. Governments, on the other hand, are charged with the responsibility of ensuring that they keep implementing austerity measures even amidst opposition from a section of the European population. In other words, European countries face an economic situation that is a true test of whether they can maintain their solidarity and fight for the survival of the European economic bloc. Most people remain keen to see the steps taken by individual economies in the Eurozone. Nonetheless, there is no window for disi ntegration even amidst what is seen as divergent tactics by individual countries as they develop mechanisms of preventing further shocks in their economies (ââ¬Å"European union: Solidarity is under threat from crisesâ⬠2011). The financial woes in the Eurozone, according to Dadush (2013), are quite far from being over because the risk of collapse of the bond markets in the Eurozone remains active. The question of unemployment in the Eurozone rose to eighteen million unemployed people, even as more commentators predicted light at the end of the seeming endless tunnel for the countries in the Eurozone. However, Dadush (2013) faults the proclamation by European governments that the crisis in the European Union is nearing the end. It would be illogical to explore the Euro crisis without mentioning the effects of the crisis on the industries in the affected countries. In their presentation of the effects of the crisis on the European economy, Walker and Galloni (2013) reported fea rs among a substantial number of workers, especially in plants that are directly affected by the major shrinks in the economy. The example provided here is Mirafiori car-assembly plant, which has shed almost half of its employees since the beginning of the crisis. An assessment of the Greece economy by Kalafati (2012) revealed that the Greece economy was worst hit by the Euro crisis. A focus on the health care sector of Greece depicts massive cuts in expenditure on health care. Even amidst the increase in tax to finance health care, the government of Greece still has not managed to prevent the layoffs in the sector (Kalafati 2012). Salin (2012) is one of the commentators who are looking at the conflict in the Eurozone not only from the economic perspective, but also from the political perspective. Salin identifies some of the politically-inclined sentiments raised by governments in his assessment of the actions taken by governments to tackle the Euro crisis. Among these sentiments i s that the monetary system of the Euro ought to be unified with the national policies. This is termed as the centralization of the European Union. This is a political move that can be used for maintaining a single currency use by the countries for economic benefits by ensuring that states do not only see the European Union as an economic stepping stone, but also maintain a system of checks and balances in their economic operations (Salin 2012). Farrell and Quiggin (2011) note the European Central Bank has now gained more powers as a key institution of monitoring the monetary policy in the European Union. This implies the control of monetary policies in the region, thus countries in the region cannot merely rush to monetary policy options whenever they face tough economic situations like the increase in the size of sovereign debts. Though opposed by a number of countries, a strong European Central Bank is necessary for supervising the big banks across the European economic bloc, besi des ensuring that there is stability in the bond markets across the bloc (Walker Steinhauser 2013). Walker and Steinhauser (2013) assess the possibility of embracing a political union by the European Union countries. The authors ascertain the need for the political union to ensure desirable coordination of the economic policies. The signs inherent in the sentiments from a number of stakeholders show that a political union of the European Union countries is far from being realized. As it is now, the European governments seem to be preoccupied with bolstering the currency union to prevent fiscal profligacy. The European countries have realized that the monetary union that they entered into is far from being accomplished as notable in the debt crisis that almost tore the Union apart (Walker Steinhauser 2013). Conclusion and recommendation The review of the literature conducted in this paper shows that the Eurozone countries are subjected to a test on whether they can act in a manner that is consistent with the desire to keep the European Union intact. According to most researchers, there are a lot of gaps in the integration of the European Union. These can be summed into one question: Does the answer to the Euro crisis lie with integration or disintegration? A substantial number of the opinions raised by economic commentators and political economists point at the fact that countries in the region have been contemplating on whether to embrace the Euro as a single currency or whether to shun the Euro and stick to their national currencies. Even as the debate rages on whether to stick to the Euro or whether to shun the Euro, it is apparent that the countries are put between a rock and a hard place as the option to abandon the Euro could be more disastrous to economies in the region. Moving forward, the European countries should review the framework under which the rules and policies of economic integration are developed and implemented. The vital thing here is tha t the European Union members should put their heads straight when developing these policies and rules. This is aimed at making all the countries of the Union to abide by the rules because the failure to stick to the economic policies and rules is one reason why the Euro crisis came into being. European solidarity is important and should be reflected in the development of economic cooperation among countries in the Eurozone. The issue of spendthrift governments cannot arise if each of the government remains committed to the rules and policies and if other governments in the European Union remain committed to supporting a worthy economic cause for all other partners in the European Union. Prudent economic management is a vital element for each country in the European Union. As such, there is a need to look into this attribute. The Euro crisis finds its roots in the attributes of irresponsible fiscal and monetary policies by individual countries. Whether the level of irresponsibility i s promoted by the fact that these countries believe that they have a backing from other economies is something that ought to be investigated, even as the support for the implementation of austerity measures in the countries severely affected continues. The functioning of the Euro system depends on the efficient national budgets, which means that the economic construction of each country is a vital element for the survival of other countries. The political rhetoric should be eliminated from the debate, considering the fact that these countries can hardly abandon the Euro. In addition, the stakeholders have to devise a system of checks and balances for each country to avoid such a crisis in the future.

Gentic Catastrophe essays
Gentic Catastrophe essays While the 20th century was shaped largely by spectacular breakthroughs in the field of physics and chemistry, the 21st century will belong to the biological sciences. Scientists around the world are quickly deciphering the genetic code of life, unlocking the mystery of biological evolution on Earth. As a result of the new breakthrough in biology and biotechnology, our way of life is likely to be more fundamentally transformed in the next several decades than in the previous thousand years. By the year 2025, we and our children may be living in a world utterly different from anything human beings have ever experienced in the past (Rifkin 30). Some ideas in genetic science are fast growing dilemmas that society is going to have to deal with in time. Producing a superior race by altering peoples genetic code or cloning, is thought to be unethical. In the future what would stop families that can afford to program superior genetic traits into their fetuses at conception that will ensure their offspring an even greater biological advantage and thus a social and economic advantage as well. This would affect the people without an altered genetic code because as stated in Darwins theory that only the strong survive, people without altered genes would become less efficient and would not survive as well in society. Molecular biologist Lee Silver of Princeton University writes about that in a not too distant future, society will be made up of two distinct biological classes, which he refers to as the Gene Rich and the Naturals. The Gene Rich, who will account for 10% of the population, have been enhanced with synthetic genes and wi ll become the rulers of society. They would include Gene Rich businesspeople, musicians, artists, intellectuals, and athletes each enhanced with specific synthetic genes to allow them to succeed in their respective fields in wa ...

CROSS-CULTURAL MANAGEMENT Essay Example | Topics and Well Written Essays - 1250 words
CROSS-CULTURAL MANAGEMENT - Essay Example Every company across the world is trying to maximize the profitability from the opportunity it has in the global world economy. Companies are looking for the opportunities to expand their businesses and serve the international markets. International markets on one hand provide lucrative opportunities and on the other hand poses different challenges for the international business managers. Much of these challenges come due to the differences of the cultures of the target market places. Every market differs with each other in geographic specifications, customer demographics, consumer choices and preferences, taste, culture and traditions and in various different aspects. It is very important for the international businesses to cater the needs of different markets by responding to different environmental factors. One of the most important issues for the business organisationsââ¬â¢ in the present business scenario is ââ¬ËCultureââ¬â¢. Culture has been defined in different ways by academicians, sociologists, researchers and various experts from different fields. Hofstede (1980) has regarded it as ââ¬Ëcollective programming of the mindââ¬â¢. This collective programming allows people to distinguish the members of one group from the other. Maanen and Schein (1979) has defined culture as values, beliefs, and expectations that members of a group come to share. Success and failure of any project of organisation is subject to its culture and culture of the people working in/with it. Organization culture allows its employee certain degree of freedom, innovativeness and support. It depends on leadership for the mission, vision and approach. Employees of any organization must follow the vision of management in order to achieve desired results. The components of organizationââ¬â¢s culture are as follows: Mooij and Marieke (2004) state ââ¬Å"Organization culture is collection of vision, values, norms, beliefs and attitude of an organization.â⬠Organisation culture is one

The fact that the new prospective engineering consulting company has secured a contract for 12 months only poses the danger of the likelihood of a future job and financial crisis, on the event that the contract is not renewed. This would mean that the three partners would be left jobless and without a source of finance to support their lives. Consequently, it is important that a concrete plan is laid down to ensure that the new engineering consulting opportunity goes beyond the single contract that has been secured into a fully-fledged engineering consulting entity that will obtain more contracts from different clients. This way, the future of the new opportunity will be secured, which means that the business opportunity will become sustainable. Therefore, the plan for developing new partnership firm will entail: The opportunity cost analysis assesses the value of the opportunity than an individual has to forego, in order to pick on an alternative opportunity (Lauer, 14). On the other hand, the Cost Benefit Analysis is applied towards assessing the benefits and the costs that the new opportunity has to offer, and then comparing between the costs and the benefits, to determine whether to take the new opportunity or not. Where the costs are more than the benefits, then the new opportunity should not be taken. However, where the benefits of the new opportunity supersede the costs, then the new opportunity can be taken. In this respect, the first stage in the process of developing new partnership firm entails a personal reflection in relation to the question; what is my ultimate goal for my career and

Ampicillin and Kanamycin Resistant Bacteria Comparison
Ampicillin and Kanamycin Resistant Bacteria Comparison Antibiotic use throughout the world has increased tremendously over the decades. In the past, antibiotic resistance was most prevalent in areas of frequent antibiotic use, such as in medical or laboratory settings. However, the increasing use of antibiotics and antibacterial products outside of hospitals, such as in homes and schools, echoes the expansion of antibiotic resistant bacteria (LBC Biology Staff, 2010). One major source of the growing problem is that antibiotics are being over prescribed by doctors to millions of people around the world. It is currently believed that about only half of the antibiotics prescribed to patients are administered properly (Levy, 1998). In addition to over prescription by doctors, many patients misuse the antibiotics and further increase the spread of resistance. For example, some patients discontinue use of antibiotics upon feeling symptom relief, not at the end of their antibiotic schedule prescribed by the doctor. In actuality, patients are ki lling off the weakest bacteria, causing temporary relief, and allowing the stronger and more resistant bacteria to multiply at a faster rate (Levy, 1998). This and other types of antibiotic misuse have promoted the growth of strains of bacteria with resistance to antibiotic attack. This can be seen through studies that have shown Tetracycline resistance by normal human intestinal flora that exploded from 2% in the 1950s to 80% in the 1990s (Criswell, 2004). Other studies have shown Kanamycin, an antibiotic from the 1950s, has become clinically useless as a result of the prevalence of Kanamycin-resistant bacteria (Criswell, 2004). It has become visible that the development of resistance to any antibiotic, new or old, will happen in a matter of time (LBC Biology Staff, 2010). Due to the inevitability of mutation, natural selection, time and environmental conditions, resistance will be seen in more common areas like work and home. As a consequence of the every growing expansion of antiobiotic resistance, places previously thought to be uncontaminated like schools and homes have become overwhelmed with antibiotic resistant bacteria. In one household study, it was discovered that kitchen sinks contained many different types of resistant bacteria, primarily from food waste and human hands (Rusin et al., 1998). Only the application of strong bleaches and specific cleaning products on a regimented cleaning schedule led to a decreased amount of bacteria in kitchen sinks (Rusin et al., 1998). The cleaning products used in this study did not contain antibacterial ingredients, which helped reduce the spread of resistance by killing all bacteria instead of the most susceptible strains. Antibacterial products and cleaning supplies are less effective and in turn can lead to reproduction of stronger antibiotic resistant bacteria. The large amount of antibacterial cleaning products, food and waste combined with the constant water supply in sink drains allows for a greater chance of survival of antibiotic-resistant bacteria (Levy, 1998). Optimal conditions for bacterial growth with a wet environment cause a higher frequency of bacterial transmission of resistance (Perryman and Flournoy, 1980). In scientific laboratories, regulations are in place to monitor the disposal of solid and liquid wastes. Some regulations include specific waste baskets for toxic or contaminated substances and use of certain sinks only when dealing with harmful liquids in laboratory settings. This ensures that unnecessary amounts of harmful substances that could lead to resistance are not continually poured down laboratory sink drains. However, no such regulations are in effect in household environments. In a study performed in Oklahoma City the extent of growing antibiotic resistance was seen in multiple environments. Bacterial samples were gathered from sink drains in the Veterans Administration Medical Center, libraries, private homes, shopping centers, and other similar environments for comparison (Perryman and Flournoy, 1980). The goal of the experiment was to determine the types of resistant bacteria that were most prevalent in sink drains, the abundance of bacteria in sink drains, and the life span of bacteria in dry and wet environments (Perryman and Flournoy, 1980). Through testing, bacteria were found to have longer life spans in wet environments than in dry environments, and many bacteria survived for over 180 days in wet environments (Perryman and Flournoy, 1980). The high survival rate of bacteria in areas with constant water supply, such as in laboratory and kitchen sinks, supports the prediction that sinks are ideal environments for ample bacterial growth. In the afore mentioned study, bacterial growth occurred on plates containing the antibiotics gentamicin and amikacin, and it was determined that the sink drains from the medical hospital contained the highest amount of antibiotic resistant organisms. Overall, 88% of the sink drains sampled from the Veterans Administration Medical Center contained some type of antibiotic resistant bacteria (Perryman and Flournoy, 1980). While bacteria could come from other sources such as the patients and tap water, the great quantity of antibiotic resistant bacteria in all environments illustrates the need for a reduction in the overuse of antibiotics and the essential awareness of the consequences. Places with high levels of exposure to antibiotics and antibacterial products provide ideal environments for bacteria to develop resistance through replicated mutations or transmissions between bacteria. Some factors that severely add to the growing problem of antibiotic resistant bacteria include increased applications of antibacterial soaps and cleaning products, over prescription of antibiotics by doctors, misuse of antibiotics by patients, and improper care of waste products (Levy, 1998). Bacteria can become resistant to antibiotics through genetic mutation, transfer of the mutation between bacteria, or transmission of the mutated DNA on a plasmid between bacteria when the resistant gene is carried on the plasmid DNA. A plasmid is a relatively small piece of circular DNA that is self replicating and independent of the chromosomal DNA of the cell. Resistant chromosomal DNA and plasmid DNA can be transmitted to the next generation through cell replication. Plasmids can be passed th rough bacterial conjugation, which involves a bacterium copying the plasmid with resistant DNA and inserting the copied plasmid into a second bacterium. Plasmid DNA can also be transferred through bacterial transformation when plasmid DNA invades another bacterium and is incorporated into the bacteriums DNA (Cognato, 2010). Understanding these problems and the mechanisms of resistance transmission is the first step in preventing further development of resistant strains of bacteria. The focus of the experiment at hand is to determine whether the bacteria located in a laboratory sink or in an apartment garbage disposal contains more antibiotic resistant strains. It was hypothesized that the apartment garbage disposal would contain more antibiotic resistant bacteria than the laboratory sink. This is due to the abundance of contaminated materials that pass through garbage disposals in comparison to the regulated materials that pass through laboratory sinks. The null hypothesis is that the amounts of antibiotic resistant bacteria that exist in the garbage disposal sink and laboratory sink will be equal. Many steps were needed to accomplish this research and obtain the sample bacteria to determine the resistance. Samples from the laboratory sink and the apartment garbage disposal were swabbed on agar plates to obtain a culture of bacteria. Colonies were selected based on growth and seclusion from the bacterial lawn. Individual bacteria were then streaked on master patch plates for each environment. After the bacteria had grown, individual colonies were selected to be streaked on antibiotic plates containing Ampicillin, Kanamycin, and Tetracycline. Antibiotic resistant bacteria were chosen from the antibiotic plates, separated and characterized. Next, plasmids from the antibiotic resistant bacteria were isolated and spliced using restriction endonucleases to determine band length of resistant plasmid DNA to help identify the type of bacteria. Competent E. coli cells were transformed with the control plasmid DNA to convey antibiotic resistance and support bacteria identification. Final ly, the bacterial DNA was replicated by polymerase chain reaction to amplify the 16S rRNA gene in hopes to obtain sequencing information of a known bacterium. It was predicted that resistant bacteria, for all antibiotics, will be Gram negative due to easier entry of resistant plasmid DNA into the cell. Bacteria with a thin cell wall layer and an outer membrane surrounding the peptidoglycan layer are Gram negative. Bacteria with a thick wall layer that do not have the peptidoglycan layer surrounding are Gram positive. Gram identity was verified through Gram staining, a KOH test, and observing growth on a MacConkey agar and Eosin Methylene Blue Agar plate. Methods Swab Plates A sterile cotton swab saturated in sterile phosphate-buffered saline was used to gather samples from the laboratory sink and an apartment garbage disposal. Bacterial samples from the disposal and lab sinks were collected from the underside of the drain. Bacteria were then swabbed onto Lysogeny broth agar plates (three per environment). Plates were placed into an incubator for 24 hours at 37à °C. Following the incubation period, plates were removed, parafilmed, and refrigerated at 4à °C until needed. Master Patch Plates Master plates were made by placing sixteen individual colonies onto a 44 grid on Lysogeny broth (LB) only plates. An inoculation loop was used to transfer the 16 individual colonies from the sample plate onto a grid of the master plate. Plates were labeled with D for the apartment garbage disposal and L for the laboratory sink along with a number (1, 2, or 3) to distinguish between swabbed samples. Plates were incubated at 37à °C for 24 hours, removed, sealed with parafilm, and refrigerated at 4à °C until needed. Antibiotic Patch Plates Antibiotic agar plates were made by mixing 8.4g agar with 12g LB powder and 600mL of distilled water (dH2O), and then autoclaved. After cooling, 2.4à µL of Ampicillin, 1.2à µL of Kanamycin, or 2.4à µL of Tetracycline were added appropriately and plates were poured. One colony per grid of the master patch plate was obtained with an inoculation loop, and the bacteria were transferred in a line onto a corresponding grid on the antibiotic plates. The number of squares that contained bacterial growth was observed and recorded. One colony of the bacteria grown on the antibiotic patch plates was then streaked onto a new antibiotic plate to obtain individual colonies of bacteria for further study. Miniprep A liquid culture was performed in preparation for the Promega Wizard Plus SV Miniprep DNA Purification System, which was used to isolate plasmid DNA from antibiotic resistant bacteria. First, 5à µL of antibiotic was added to a 5mL tube filled with a liquid medium made of LB. A single colony of bacteria was added to the medium and placed in a shaker at 37à °C for 24 hours. The liquid culture was then transferred into an Eppendorf tube and centrifuged for 5 minutes at 4,400rpm. Liquid media waste was disposed of and the pellet was thoroughly re-suspended in 250à µL of Cell Resuspension Solution. If the bacteria were Gram positive, 63à µL of lysozyme would be added to the solution. Since the bacteria studied was Gram negative, the process continued with the addition of 250à µL of Cell Lysis Solution was added to the Eppendorf tube containing the resuspended bacterial solution and the sample was mixed. Subsequently, 10à µL Alkaline Protease Solution was added, mixed, and incubated for 5 minutes at room temperature. Then, 350à µL Neutralization Solution was added, mixed, and centrifuged for 10 minutes at 13,500rpm. A Spin Column was inserted in a Collection Tube and the clear lysate was decanted into the Spin Column. This was centrifuged for 1 minute at 13,500rpm and the flowthrough was discarded. The Spin Column was replaced, 750à µL of wash solution was added, and the solution was centrifuged for 1 minute at 13,500rpm. The flowthrough was discarded, and this process was repeated with a 250à µL wash. The solution was centrifuged for 2 minutes at 13,500rpm. The Spin Column was transferred to a 1.5mL Eppendorf tube. Finally, 50à µL of Nuclease-Free Water was added and then the solution was centrifuged for 1 minute at 13,500rpm. The column was discarded and the DNA was stored at -20Ãâ¹Ã
¡C. Gel Electrophoresis DNA electrophoresis was used to determine the length of the plasmid DNA of the environmental samples and Blue plasmid control (pKAN). First, 0.7g of agarose powder was added to 70mL of 1X TBE. The solution was heated in a microwave for 1 minute so the agarose powder was completely dissolved. After the mixture cooled, 3à µL of Ethidium bromide was added and the gel was taken out of the mold and put on the rig. The gel was submerged in a 1X TBE buffer. The wells of the gel were filled with 10à µL of a mixture containing 8à µL of plasmid DNA and 2à µL of plasmid dye, and the gel ran for 60 minutes on 80 volts. The 1% agarose gel was viewed under an ultraviolet light to compare lengths of DNA with the 1KB ladder. Gram Staining Gram staining was used to determine the Gram identity of bacteria. Bacteria that are Gram negative stained red and bacteria that are Gram positive stained violet. A colony of bacteria was added to an Eppendorf tube with 400à µL of dH2O. After vortexing, 5à µL of the solution was pipetted onto a slide. Once dry, the slide was passed over a flame to affix the bacteria to the glass, preventing the removal of bacteria. The slide was flooded drop-wise with crystal violet and iodine, and rinsed with dH2O for 5 seconds after the addition of each reactant. Ethanol was added until the color was no longer emitted, then rinsed with dH2O for 5 seconds. Safranin was added drop-wise for 1 minute and then rinsed with dH2O for 5 seconds. The slide was observed under a microscope to determine Gram identity. KOH Test The KOH test for Gram positive and negative bacteria was begun by pipetting 20à µL of 3% KOH on a slide. After adding one clump of bacteria to the KOH, the consistency of the solution was observed. If the solution was thick, viscous and adhered to the inoculation loop, the bacteria were Gram negative. If the solution was thin and not viscous, the bacteria were Gram positive. MacConkey Agar Plate A MacConkey agar plate was streaked with antibiotic resistant bacteria from the garbage disposal and laboratory sink. After incubation at 37Ãâ¹Ã
¡C for 24 hours, the plates were observed for growth to indicate Gram negative bacteria. The MacConkey agar plate also signaled lactose fermentation with the appearance of pink colonies. Eosin Methylene Blue Agar Plate (EMB) An EMB plate was streaked with antibiotic resistant bacteria from the apartment garbage disposal and the laboratory sink as well as a positive E.coli control. After incubation at 37Ãâ¹Ã
¡C for 24 hours, the plates were observed for growth to indicate Gram negative bacteria. The EMB agar plate indicated strong lactose fermentation through the appearance of dark green metallic colonies and a lesser degree of lactose fermentation through the appearance of purple or pink colonies. Restriction Digest Restriction enzymes cut the control pKAN DNA at specific restriction sites identified by the NEBcutter V2.0. The enzymes used in restriction digest were BamHI and EcoRI in Buffer II, and PvuI and PstI in Buffer III. The reaction solution used in restriction digest consists of 10à µL of DNA, 1à µL of each enzyme, 2à µL of NEBuffer, and 7à µL of de-ionized distilled water (ddH2O) added together in an Eppendorf tube. The solution was centrifuged at 14,500rpm for 30 seconds and then incubated for 24 hours at 37Ãâ¹Ã
¡C. A plasmid map created from the NEBcutter V2.0 was compared to a gel electrophoresis run on a 1% aragose gel with plasmid DNA. The gel electrophoresis compared Blue plasmid (pKAN) DNA that was uncut with the Blue control plasmid (pKAN) that was cut with restriction enzymes. Transformation After plasmid DNA preparation, 22à µL of E. coli competent cells were added to three separate Eppendorf tubes. In one tube, 5à µL of control DNA, pKAN, was added and stirred with the pipette tip. In the second tube, a negative control was made with the addition of 5à µL of dH2O that was then stirred with a pipette tip. In the third tube, a positive control was made with the addition of 1à µL of known pKAN, and the solution was stirred with a pipette tip. The tubes were then incubated in ice 30 minutes. The cells were heat shocked for 45 seconds at 42Ãâ¹Ã
¡C and then placed on ice for 2 minutes. 250à µL of pre-warmed (37Ãâ¹Ã
¡C) SOC medium was added to all three of the Eppendorf tubes, and the tubes were then incubated in a shaker at 37Ãâ¹Ã
¡C for 1 hour at 2,250rpm. Upon removal from the incubator, 75à µL of each transformation were spread onto plates with a sterilized hockey stick. The transformed control DNA, pKAN, cells and the negative control dH2O transformed cell s were spread onto LB only plates, ampicillin antibiotic plates, and kanamycin antibiotic plates to determine if resistance to antibiotics was transferred in the transformation. The transformed positive control, known pKAN, cells was spread onto a LB only plate and a kanamycin plate since pKAN is known to be resistant to kanamycin. Plates were incubated for 24 hours at 37Ãâ¹Ã
¡C and numbers of resistant bacterial colonies were observed. Bacterial growth on the control DNA, pKAN, transformation antibiotic plates would signal resistance to the antibiotic in the plate, and growth on the LB only plate would signal the existence of bacterial cells from the transformation. No growth on the dH2O negative control plates containing ampicillin and kanamycin antibiotics would signal a correct transformation as long as there was bacterial growth on the LB only plate. Growth on the positive control, known pKAN, transformation plate signaled the correct transfer of kanamycin resistant plasmid DNA into the competent E.coli cells. Polymerase Chain Reaction The Polymerase Chain Reaction (PCR) involved mixing a reaction cocktail that included 80Ã µL of Nuclease-free water, 10Ã µL of 10X Thermopol buffer, 3Ã µL of 10mM dNTPs, 2Ã µL of 11F @ 10Ã µM, 2Ã µL of 1492R @ 10Ã µM, and 1Ã µL of Taq polymerase @ 5000U/mL. The solution was then mixed through vortexing. Subsequently, 22Ã µL of the cocktail was transferred to each of the 4 PCR tubes. A small portion of each bacterial colony was added to SOC medium and mixed. Then 5Ã µL of SOC medium with bacteria was added to each tube. Tube 1 had environmental bacteria, tube 2 had different environmental bacteria, tube 3 had the control E.coli and 5Ã µL of H2O was added to tube 4. The reactions were placed in the thermocycler in C4. The PCR cycling program consists of five steps. The first step is pre-denaturation in which the PCR mixing reaction cocktail is heated at 95Ã °C for 5 minutes. The second step is denaturation, which involves heating the reaction cocktail at 95Ã °C for 30 seco nds to unwind and separate the DNA. The third step is annealing, which is run at 50Ã °C for 30 seconds to allow the 11F and 1492R primers to attach to the DNA template strands. The fourth step is elongation, which is run at 72Ã °C for 45 seconds to allow the DNA polymerase (Taq polymerase) to add dNTPs and replicate the 16S gene. The fifth step is the final elongation, which is run at 72Ã °C for 7 minutes. The hold between cycles is run at 4Ã °C, and the PCR is run for 35 cycles. Gel electrophoresis was run to determine if a successful PCR reaction took place. 10Ã µL of the PCR solution from each tube was mixed with 2Ã µL of plasmid dye, and 10Ã µL of the mixtures were loaded into the wells of the 1% agarose gel. Chi Squared Test of Independence A Chi Squared Test of Independence was run to determine if a statistically significant difference exists between the numbers of antibiotic resistant bacteria from the two environments. The number of grids on the antibiotic plates was recorded only if the bacteria grew on both the antibiotic plate and the LB only plate. The test was run on Vassar Stats and gave a p-value to correspond to the data and indicate if there was a significant difference. Results Swab and Master Patch Plates After the incubation period of 24 hours at 37 C, the swab plates, labeled L for laboratory sink samples (L1-L3) and D for garbage disposal sink samples (D1-D3), were observed and found that 100% of the environmental bacteria grew (Figure 1). Bacteria growth in both environments was indicated by white colored spots or streaks within the plates grid. Master plates were observed from both experimental environments and found to have growth on all of the 16 grids on each plate (Figure 2). Antibiotic Patch Plates From the garbage disposal sink, the three samples all had some level of growth (Figure 3). The following percentages were calculated by dividing the number of grids with bacterial development on the antibiotic plates by the number of grids with growth from the LB plates (Table 1). Plate D1 showed 100%, 62.5%, 0%, and 100% growth on the Ampicillin, Kanamycin, Tetracycline, and LB only plates respectively. Plate D2 demonstrated 93.75%, 93.75%, 0%, and 100% growth on the Ampicillin, Kanamycin, Tetracycline, and LB only plates respectively. Plate D3 showed 93.75%, 75%, 0%, and 100% growth on the Ampicillin, Kanamycin, Tetracycline, and LB only plates respectively. From the laboratory sink, all samples had bacteria development (Figure 4). Plate L1 demonstrated 100%, 93.75%, 12.5%, and 100% growth on the Ampicillin, Kanamycin, Tetracycline, and LB only plates respectively. Plate L2 showed 100%, 73.33%, 6.67%, and 93.75% growth on the Ampicillin, Kanamycin, Tetracycline, and LB only plates respectively. Plate L3 demonstrated 57.14%, 42.86%, 7.14%, and 87.5% growth on the Ampicillin, Kanamycin, Tetracycline, and LB only plates respectively. Chi Squared Test of Independence Data obtained from the number of antibiotic resistant colonies on the antibiotic patch plates was used to run the Chi-squared Test of Independence for Ampicillin and Kanamycin resistant bacteria. For Ampicillin resistant bacteria, the p-value obtained was 0.74. With one degree of freedom, the Chi-squared critical value of 3.84 obtained from a Chi-squared Distribution Table in comparison to the Chi-squared statistical value denoted no statistically significant difference. For Kanamycin resistant bacteris, the calculated p-value was 0.81. With one degree of freedom, comparison of the Chi-squared critical value of 3.84 found in a Chi-squared Distribution Table and the Chi-squared statistical value demonstrated no statistically significant difference (Table 1). Gram Staining, KOH, MacConkey Agar and Eosin Methylene Blue Agar Plates Four tests were used to determine the gram identity of bacteria from the experimental environments. The results showed that the three environmental bacteria slides were stained pink indicating gram negative bacteria (Figure 5, Table 2). For the KOH test, all three samples from both environments appeared viscous and thick, indicating gram negative bacteria (Table 2). The MacConkey Agar Plate was divided into three sections for the different antibiotic resistant bacteria. The environmental bacterial sample in Section 1 was obtained from the Ampicillin antibiotic plate L2 grid #3. The bacterial sample in Section 2 was obtained from the Kanamycin antibiotic plate L2 grid #14. The bacterial sample in Section 3 was obtained from the Kanamycin antibiotic plate D2 grid #16. All three samples in the three sections grew bacteria that were stained pink, indicating Gram negative bacteria that ferment lactose (Figure 6, Table 2). The Eosin Methylene Blue Agar Plate was sectioned off into four par ts and bacteria from three environmental samples and one E.coli positive control were plated. The bacterial sample in Section 1 was taken from the Ampicillin antibiotic plate L2 grid #3. The bacterial sample in Section 2 was obtained from the Kanamycin antibiotic plate L2 grid #14. The bacterial sample in Section 3 was gathered from the Kanamycin antibiotic plate D2 grid #16. The bacterial sample in Section 4 was obtained from an E. coli plate that was known to be Gram negative. Pink colonies formed in all four sections, signaling Gram negative identity of the bacteria and lactose fermentation (Figure 6, Table 2). Mini Prep and Gel Electrophoresis Promega Wizard Plus SV Miniprep DNA Purification System was run to isolate plasmid DNA. This plasmid DNA was run on a 1% agarose gel. The lengths of bands in Trial A could not be determined because the DNA in the wells did not run with the ladder. The Blue control plasmid, which was pKAN, was located in lane 3 in Trial A and Trial B and was used to indicate a successful Miniprep. The band length of the pKAN control DNA in Trial B was about 4,200 base pairs. An environmental plasmid found on Ampicillin streak plate L2, grid #3 was used in lane 7 in Trial A and lane 5 in Trial B. In Trial B, the base pair length of the environmental bacteria plasmid used in lane 5 could not be determined due to the appearance of many bands of varying length. An environmental plasmid from Kanamycin streak plate L2, grid #14 was used in lane 5 in Trial A and lane 7 in Trial B. The band length of this environmental plasmid in Trial B could not be determined due to the faint appearance of a band greater th an 10,000bp. Another environmental plasmid from Kanamycin streak plate D2, grid#16 was used in lane 6 in both Trial A and Trial B. The band length of this environmental plasmid in Trial B also could not be determined from the faint appearance of a band greater than 10,000bp (Figure 7). Restriction Digest In Trial A, restriction digest was used to cut the Blue control pKAN DNA with the enzymes BamHI, EcoRI, PstI, and PvuI. Lane 3 displays pKAN cut with PstI and PvuI. Lane 4 displays pKAN cut with BamHI and EcoRI. The lengths of the bands shown are about 4,000bp, 3,000bp, 2,500bp, 1,500bp, and 1,200bp.The lengths of the bands shown are about 1,700bp, 1,100bp, 750bp, 600bp, and 500bp. Lanes 5-8 contained environmental bacterial DNA that was cut with BamHI, EcoRI, PstI, and PvuI as well, but no bands were observed (Figure 8). In Trial B, restriction digest was used to cut pKAN DNA with only the enzymes BamHI and EcoRI. Lane 3 displays pKAN that was cut with BamHI, showing a band length that is about 4,200bp. Lane 4 shows pKAN that was cut with EcoRI, and the band lengths shown are about 8,000bp, 5,000bp, and 4,000bp. Lane 5 displays pKAN that was cut with BamHI and EcoRI, and the band lengths shown are about 4,100bp, 3,100bp, and 2,000bp. Lane 6 shows pKAN that remained uncut with a band length of about 4,200bp (Figure 9). Transformation Transformation was performed to convey resistance carried on plasmid DNA into competent E. coli cells. Blue plasmid control DNA (pKAN) was used for the transformation, which was successful. This was indicated by the growth of transformed bacteria on Kanamycin antibacterial plates (Figure 10). Polymerase Chain Reaction A Polymerase Chain Reaction (PCR) was used to amplify and prepare the 16S gene of rRNA. Gel electrophoresis was run on the PCR product to determine if a successful PCR reaction had taken place. Lane 3 contains PCR product from the Kanamycin plate L1 grid #14 and lane 4 contains PCR product from the master patch plate D3 grid #16. Bands were not seen in these lanes containing environmental bacteria, signaling an unsuccessful PCR. Lane 5 displays the negative water control without bands. Lane 6 shows the positive E. coli control PCR product with a band length of about 2,000bp (Figure 11). Discussion The study showed that no statistically significant difference existed between the amount of antibiotic resistant bacteria in the garbage disposal and laboratory sink and it also characterized all of the environmental bacteria as Gram negative. To determine the amount of bacteria located in the experimental areas, many tests were utilized to analyze the bacterium. Patch plates containing Tetracycline, Ampicillin, Kanamycin and LB were made in order to verify antibiotic resistant bacteria and growth. The plates with bacterial growth that was resistant to Ampicillin and Kanamycin were used in a statistical analysis to determine a correlation between the amounts of growth and the two environments. Our prediction that the amount of bacterial growth from the garbage disposal sink in Capitol Villa would be greater than the Lyman Briggs lab sink in C5 was refuted due to the Chi-squared Test for Independence that showed no statistically significant difference. We failed to reject the null hyp othesis that no difference existed between the amounts of antibiotic resistant bacteria found in each environment. A Chi-squared Test for Independence was run to compare the amounts of antibiotic resistant bacteria on the Ampicillin and Kanamycin plates. Tetracycline was not used because no data indicated resistance. The existence of Ampicillin and Kanamycin resistant bacteria in both the garbage disposal and the laboratory sink is unsurprising due to the widespread clinical use of both antibiotics over the past decades (Criswell, 2004). For Ampicillin, a total of 178 bacterial streaks grew between the two environments and a p-value of 0.74 was calculated. With one degree of freedom, the Chi-squared critical value of 3.84 obtained from a Chi-squared Distribution Table in comparison to the Chi-squared statistical value denoted no statistically significant difference. For Kanamycin, 162 streaks grew between the two environments and a p-value of 0.81 was calculated. With one degree of freedom, the a comparison of the Chi-squared critical value of 3.84 found from a Chi-squared Distribution Table to t he Chi-squared statistical value denoted no statistically significant difference as well. Therefore, the prediction that the garbage disposal sink would contain more antibiotic resistant bacteria than the laboratory sink was rejected. To further understand why bacteria were resistant, four tests were run to categorize the Gram identity of the environmental samples. The structure of the bacteria plays a large role in determining resistance. Importantly, it is easier for the plasmid DNA to penetrate a Gram negative bacterium due to the lack of an outer membrane around the peptidoglycan layer. The Gram staining process showed pink rod shaped bacterium, demonstrating that the bacteria was Gram negative. The KOH tests resulted in a viscous substance, indicating that all the environmental bacteria obtained from the garbage disposal and the laboratory sink were Gram negative. The MacConkey agar plates identified the bacteria to be Gram negative through growth on the plate. The growth on the plate was a pink color, signifying lactose fermentation from the bacteria. The environmental bacteria developed pink colonies on the EMB agar plates, further supporting the Gram negative identity and a low production of lactose fermen tation of the environmental bacteria gathered from the garbage disposal and laboratory sink. Gel electrophoresis was used in determining the existence and length of environmental plasmid DNA. The Miniprep isolated the plasmid DNA from the bacteria, but upon running the gel, it was discovered that no environmental plasmid DNA was present. The absence of bands
