Pelagic food-web in the Southern Ocean - Essay Example Autotrophs are grazed by herbivores that in turn are consumed by carnivores. A number of trophic levels form the food web with primary producers at first level, the second level comprising herbivores, third level comprising carnivores and the next level comprising carnivores that eat carnivores. Pelagic food web exchanges take place in the water column. The primary producers of the food web are phytoplanktons which are consumed / grazed by the herbivores zooplanktons which are in turn consumed by filter feeding planktivores or piscivores – carnivores or eating fish that eat other types of animals. In pelagic food web omnivory is common with organisms obtaining food from one or two trophic levels. For example, salmon eats the planktivores juvenile fish but also eats zooplanktons that are euphausiids (Marine Biology). The pelagic food chain is comprised of a diversity of organisms including bacteria, heterotrophic and autotrophic nano and microplanktonic organism. The presence of microbial forms in Antarctic waters is underestimated due to the dogma that the region features a short and simple food web that are not accounted due to technical limitations. However, a research on the food web indicates an abundant distribution of heterotrophic ciliates and flagellates in polar waters with the presence of microbial assemblage that inhabit the water column and sea ice. Estimates of grazing point out that they are the important consumers of the Antarctic food web. Though seasonality is not accounted, heterotrophic nano and microplankton are formed after an autotrophic bloom and reach a maximum biomass during summer (Ross, R.M., Hofmann, E.E. & Quetin, L.B. 1996 p.155). The ecosystem in southern ocean is highly influenced by factors like climate, ocean currents and ice. The amount of ice cover results in a competition between species of the primary producers which in turns affects the competition among zooplankton species that

International Institute of Finance - Essay Example IIF has a robust Knowledge space in the form of its website which is used to provide above packaged knowledge in part of full to public and members. Knowledge events include briefings, meetings, seminars, conferences, workshops, staff visits to information sites, collaborative efforts to bring together global financial lenders, etc. Firstly, CRM can help IIF to handle the increase in its membership base (from 150 in 1996 to 20,000 in 2001). CRM will handle list of members with appropriate information, such as contacts, areas of interests, history and other related information. So IIF can create groups and subgroups of members, classify them by various parameters, send them adequate promotion information, and notify them about potentially interesting events. Although IIF does not have revenue goals, all these improvements will raise quality of services, members' satisfaction and loyalty and facilitate work of staff of IIF. Secondly, CRM can provide staff and members of IIF access outside of the office that increases flexibility and mobility for both staff and members. It is true that top managers of banking and financial institutions travel a lot, so access to IIF knowledge base via Internet from anywhere on Earth will be very useful for them. ThThirdly, CRM will provide ground for interaction of members with potential members, for example, via newsletters, online discussions, publications, meetings and other forms of communications. So marketing to potential members will be supported. The proposed CRM is much better then Access database, what IIF is currently using. To begin with, use of Access was limited to IIF premises; its traveling staff could not access it in travel. Also, it had limited versatility in that it abruptly aborted when accessed by more than five users simultaneously. Then, membership-billing system was separate and membership department sent bills manually to members. Similarly events department had to collect events' registration details from IIF website and re-key it in the Access database system. So Access database does not meet current needs of IIF. The new CRM must meet management's strategic objective to have robust activities even with incredibly increased client base and offer members a comprehensive user interface. More importantly, the management wanted an integrated view of CRM, billing, accounting and events management alongside making its databases accessible to mobile staffers and public-members or non-members. The new CRM included not only all of the above in its design but also had the capability to handle increased staffers' research efforts warranted by dynamic economic scenarios in emerging markets. The value of designing the system with an open architecture Before talking about open architecture, I would like to mention that an architecture-first approach would really help in the situation. An early focus on the architecture results in a solid foundation for the 20% of the stuff (requirements, components, use cases and risks) that drives the overall success of the project. Getting the architecturally important components to be well understood and stable before worrying about the complete set of different features should make

Role of a Smooth Economy

Role of a Smooth Economy In an economy, in order for a country to have balance it must have stability and growth to become successful and function properly. The economy is very important, as it is as defined as the wealth and resources of a country or region. A strong economy brings wealth and stability to consumers, borrowers, purchasers, savers, and lenders. We also need a balanced financial system that runs smoothly to go along with a strong economy. One might ask what is the financial system? It is a network of markets and institutions that bring together households, businesses, and governments. When the financial system begins to struggle or becomes unstable everyone is affected. Chaos is an inevitable result when the financial system is not stable and we face the possibility of recessions. The financial system helps the economy keep a healthy status but lack of control and other factors such as corruption, greed, and too much debt have kept it from functioning properly. Financial systems provide great services such as data on risk sharing, liquidity and information. The risk in finance are high because many of the times we are dealing with uncertainty as it is difficult to determine how well organizations may do. The services that the financial system provides is the fact that it allows risk sharing and this helps spread and transfer risk. The transferring of risk is a good thing because it ensures not just one entity is affected when a great loss occurs. Risk sharing is a great feature the financial system provides and â€Å"it allows savers to hold many assets† (Hubbard, O’Brien, 2012 pg 13). The second service the system provides is liquidity. Savers and borrowers are provided with ease that an asset can be exchanged for money. Lastly we know that the financial system provides information and when dealing with money it is important that everyone involved is well informed on the loss or risk that one faces. The services the financial system provides are essential to the functioning relationship between everyone involved and are a great benefit that citizens receive. It has been demonstrated that when these things are not watched and monitored financial crisis happen. Countries with severe poverty have a weak financial system in place. In order for everything to run smoothly positive relationships much exist. Banks must have loans in order to collect interest rates to keep running and consumers must be well informed and protect themselves from abuse and fraud. It is all a revolving relationship where everyone involved benefits in some way and in order for it to continue, the parties involved must remain courtesy and no abuse of one another. Countries such as Mexico and Greece are an example of just what a bad economy looks like. Greece is currently facing a difficult situation as they have major debit issues and banks are running out of solutions. In the United States as we all know, we have been forced to face financial crisis in the past with the Great Depression and the Great Recession of 2007. In both situations the country faced unemployment and a rise in poverty that at times seemed difficult to overcome. In The Recession of 2007, the financial system was unstable and banks struggled to conduct business as necessary but did not have bank failure as in the 1930’s. Liquidity and funding was a problem that was a major key role in both time recessions. Although the economic decline was not as severe in 2007 as in 1930 the country was very much hurting. We must note both crises were preceded by innovations in consumer finance in the 1930s we saw installment on consumer credit and in the 2000’s banks ramped up lending in regards to real estate and securitization of mortgages. (Geewax, npr.org). The biggest difference of course is that the Great Depression lasted approximately 43 months oppose to the Great Recessi on that lasted 18 months. A big difference noted between the two crises was the United States response; in The Great Depression they raised taxes and cut spending and in 2007, they issued a Federal stimulus plan that gave fiscal relief to states to lessen the impact if tax increases. Both of these hard times displayed what a lack of financial stability looks like and just how far debt can take the country. Inflation and bad planning leads the countries to suffer banks have a hard time climbing out of the debt. Improper lending and borrowing really created a problem that occurred in 2007 and many did not thing the United States would recover. The Federal Reserve is a large bank that lends the United States money and throughout history they have obtained more and more control. Although many argue whether or not they should exist or have power the reality is they have much control over the financial markets as they play a major role in regards to money or U.S. currency. In 2008 the SAFE Act was established as a precaution to stop some issues from occurring. The SAFE Act put into effect the federal registration requirements that an individual that is acting as a residential mortgage loan originator and is employed with an company that is regulated by the Board of Governors of the Federal Reserve System, Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, Office of Thrift Supervision, National Credit Union Administration, or the Farm Credit Administration. (Federalreserve.gov). They also developed the Troubled Asset Relief Program in which the government attempted to address and improve the s ubprime mortgage crisis, the program for the most part ended in 2014. They also implemented the federal takeover of Fannie Mae and Freddie Mac (treasury.gov). The housing market needed a lot of improvement after the crisis that was faced. In the current years it has become more difficult to purchase a home than before as requirements set in place are attempting to stop people from buying homes they simply cannot afford. Changes such as robust supervision and regulation of financial organizations are also among implementations for improvement. Among all of the supervision changes, we also witnessed new employment roles in the Federal Reserve in charge of supervising firms that could be a threat to financial stability. They established changes so that consumers would not be subject to financial abuse in hopes of winning back the trust of Americans across the country that lost faith in the government. Other changes were also implemented and I believe it was all in efforts to avoid the crisis from repeating itself. Many consider the changes the government made to be too much, but with what we have seen happen in past years these changes were very much needed. In conclusion, the financial system is complex and has many implications when things are not running smoothly. Factors such as loans and interest rates are what keep things flowing and when something is off balance everyone feels it one way or another. History shows us what happens when things are not ran smoothly and control is lost to inflation and greed. All of the parts that make up the financial system are important, as we must have risk, liquidity, and information to function. It is important that we have supervision in place and that risk is always assessed when dealing with borrowers and savers. The government continues to attempt to keep things running smoothly so that history does not repeat itself and money does not lose value, now how long this will last is unclear.

Genly Ai vs. Neo Essay -- Matrix Left Hand Darkness Characters Essays

Genly Ai vs. Neo Just as a child starts out unable to live on their own and then eventually is able to walk, speak, and make decisions, Genly Ai from the novel, The Left Hand of Darkness by Ursula LeGuin and Neo from the movie, The Matrix were able to grow as characters in much the same way. Genly Ais name reveals his three narrative roles throughout the novel that clearly depict his growth and change as a character. His journey begins as the reader views him as I, just a regular human. Gradually as the novel proceeds the reader finds that Genly Ai is able to transform and grow from I into eye, having blindness and insight into himself, and then finally to Ai, referred to as a scream which depicts the actual depth of his emotional existence. Neo changes and grows in much the same way. Though his name only refers to the idea that he eventually becomes this new human, he takes many of the same steps as Genly Ai in his character growth. In the beginning of the novel, Genly Ais character takes on the role of I, revealing that he is limited to himself. At this point, Genly Ai is a conventional, young, black Earthman who is confused and defensive. He lacks the insight and understanding to carry out his mission, and for the past two years he has been on Winter, he has never been able to understand or relate to any of the Gethenians. He views them as aliens and the others unable to step back and see that in reality he is the alien in this situation not the Gethenians. He is also unable to step away from his Earth prejudices and truly see the Gethenians for who they are. He believes that what is different from him is bad, a typical Human belief, which creates a barrier for him. Due to this lack of understanding of the Gethenians ... ... the new messiah for the last city of people on earth. He finally believes in himself and sees the new world in the eyes of the others. He has developed the ability to defeat the artificial intelligence within the matrix and has begun the process of restoring man to his rightful place. His old realities have been shattered, and he has fight for his life, and the future of humanity, against this dangerous group of artificial intelligence. Both characters transformed by the end of the novel and movie. They became fuller characters through the experiences they had in their strange environments. In the beginning they both took on typical society views where they thought mostly of themselves and question anything different. However, in the end of their journey they were able to see other views. They also grew as characters from within, becoming stronger individuals.

Environmental Issues of the 21st Century

â€Å"Today human actions have become major forces in the operation of the earth system. They increasingly challenge the system boundaries of the planet, which will result in fundamental, unprecedented and unpredictable changes in the earth system (UNEVEN, 2012). † This Is the most Important perspective we have to consider as we enter and currently live In the era provided by the 21st century. Everything happening In this world Is dependent or, If not, manipulated, by human beings.We have become the most superior entity on this planet to the point that we can tinker and choose our planet's destiny. Given this notion, the most infamous environmental concern which got into our senses from the time we hit this century â€Å"can [simply] be categorized according to the major themes of global environmental change- water, climate change, the marine environment, and so on (UNEVEN, 2012). † This phenomenon or change in natural trends, habitats, and, is of course, caused by the acts of us humans, being the superiors of this natural cycle.There are numerous aspects of environmental change like water, climate, etc. But what we all know Is that the reason behind these changes Is collectively bound by the excessive ND Iniquitous acts of man because of their Inventions and stubbornness. Change In water Is caused by water pollutants which come from factories and garbage which Is a product of man. Change In climate Is due to greenhouse gases which come from burning of chemically hazardous wastes which is made by man and burned by man.Change in marine environment is cause by excessive fishing, and water pollutants as well which are both acts of man and products of man. These are Just a few examples of how some aspects of environmental change are done. From here, we can derive he idea that these changes in trends and systems in nature are all put together by man and their acts. To make it a lot more concrete and practical, probably the most important environmental and social concern that has to be tackled would be the products and actions of man and how this can be grounded on awareness and ethics.This concern has reached out and affected numerous fields of science which sometimes are not really related to each other (like: tampering with evolution via biotechnology up to climate change Oval greenhouse gases) except for the sole cause of these occurrences which is man's actions. To say that the concern is solely environmental change would be a bit of an understatement. The real concern would probably be the uncontrollable acts of man.It is disturbing that a single cause could actually affect different aspects in different ways to the point that naturally-known ways and cycles are tipped by mere inventions, ignorance of man, and selfishness. Awareness in the 21st century is solely fixated on man. The man that we know of today has become that catalyst to tip eras of evolution and natural cycles that have been existing before us. The man that we know of today has become the sole manipulator by turning supposedly naturally occurring phenomenon to dissipate or to be created and run artificially.If we look around us, different environmental concerns have arose which show a single symptom; change. But all these changes and concerns boll down to one single factor; human Intervention. In this century, everything that has happened and changed, environmentally speaking, can be Justly blamed on humanity â€Å"Soc TTY NAS already confronted a most to global environmental challenges including loss of biodiversity, climate change, water and and degradation among others, and, through persistence and ingenuity, has found many solutions to these challenges.

Failure to be awarded luxurious contracts normally makes them leave or threaten to leave the organization. Take for example a player such as Christiano Ronaldo, who left Manchester United to Real Madrid, basically because he was offered a large amount of money when compared to Manchester United (Ramzan 2014). Another example includes Wayne Rooney, who is kept at the Manchester United, because of the high weekly salary that he is earning at the football club (Kennedy and Kennedy 2014). Other players minting millions of pounds, at the English Football clubs, include Eden Hazard, Peter Cech, Didier Drogba, etc. Because of the high salaries that these players are able to command, they are always booed, and criticized, in circumstances where they are not able to adequately perform in the field.
