Protists essays

Protists essays Protists are plant-like, animallike, or fungi-like organisms with one or more cells (single or multicelluar organisms). Asexual reproduction is common. It occurs by mitosis or binary fission in most species. Sexual reproduction is less common and has not been seen in many protists. Protists get food and energy one of two ways. They get their food (energy) either by using photosynthesis (called Autotrophic) or eating other protists or bacteria (called Heterotrophic). Protists are always found in damp or wet areas. They are found almost everywhere that has water. Some protists are attached to rocks and others drift on the surface of the water. The ones that float freely are called plankton. Some live in body fluids, tissues or cells of hosts. Phytoplankton are the bottom of the food chain in most fresh and sea water. Throughout the world they are responsible for 50% of organic matter. There are 3 types of protists: algae, protozoa, and slime molds. Most algae make their food using photosynthesis, which uses chlorophyll and sunlight like plants. Slime molds are something like fungi and something like animals. There are three types of slime molds, but only one is a protist. The kind that is a protest is called cellular slime mold. The word protozoa come from the Greek for little animal. They sometimes live and form colonies. Protozoa get their food by hunting other microbes. They mainly eat bacteria, but some also eat other protozoa and bits of tissue from other living things, which is called organic matter and sometimes fungi. Asexual reproduction for protozoa includes binary fission and mitosis. Some reproduce sexually during a time of their life cycle. Most protists can move. They are called Motile if the can move. There are 3 different ways protists can move: with cilia, which are hair like structures; with flagellates, which are whip like structures; and using amoeboid motion, which ...

Compare and Contrast the Egyptian Palette of Narmer and the essays

Compare and Contrast the Egyptian Palette of Narmer and the essays Narmer was the name of the Egyptian king who ruled in 3100 BCE the first dynastic period of Egypt The palette which is made of Mudstone depicts scenes in high relief and the kings name using pictographs (an early form of writing, Narmer = fish and chisel). Palettes were used for grinding and this one being found in the temple of Horus may have been used for religious ceremonies. King Narmer is the main character in the various scenes; the images show him as the great unifier, protector, and leader in Hieratic Scale. Hieratic Scale signifies the status of an individual or groups by relative size. The images on the front and back of the palette show Narmer as the absolute ruler of Upper and Lower Egypt using natural (dead enemy, soldiers and servants) and super-natural forms (Long necked feline creatures, Horus (falcon with human hands) and Bulls with human faces). Naramsin was the name of a grandson of the Akkadian King Sargon who ruled northern Mesopotamia in 2332 BCE.

The two pieces, The Palette of Narmer, and the Stele of Naramsin, share the concept of presenting a scene, which is meant to awe the viewer and ingrain the thought of Imperial Authority (Rulers either being gods or god-like). The rulers by ...

A Review of Teamwork an Episode in Allegiance, an American Drama Series

A Review of Teamwork an Episode in Allegiance, an American Drama Series Reading Television: Allegiance Consumers are indulged by media through watching television based on themes that capture their attention. Recently, I watched an episode Teamwork from the TV show Allegiance on NBC. Allegiance is about Alex O’ Conner, who is a young man that does not know that his family are Russian spies. He works for the CIA as an analyst, which results in conflict of interests. His parents work for a spy organization, who wants the files, which can potentially destroy American core values. Alex is working with the CIA to foil Rezident’s plans in obtaining the files. In the episode Teamwork, Alex confronts his parents by accusing them that they are Russian spies. Throughout this whole episode, there are stereotypical examples that portray how media views men, women, people of color, and American nationalism. This episode portrays Russian stereotypes of women, men, politics and economy. Allegiance highlights prejudices, through representation based on character behavior in different scenarios. The music, shots, and characters represents the theme of allegiance and nationalism. The scene opens with Alex demanding to know the truth from his parents about Mikeal, because his files are a threat. Alex asked accusatory questions about Mikeal and his files. As a result, Katya becomes hysterical, and throws Alex off, by confessing that she had an affair, which was just another lie. This scene, portrayed the stereotype that Russian women are gold diggers, because they only want to live comfortably and be dependent on a male figure. When Katya mentioned she attended, border school in America, it also brought up a political notion of Russia sending children to America for better opportunities. During this whole scene, the music was quick, light and dramatic. This represented Alex’s mood on how he felt when Katya constantly disappeared when he was a child. Alex represents the American ideals which are justice and liberty, however Katya and Mark represent the Russian socialist mentality. There are many instances when we watch a series when we do not know the true reason why the director choose to shoot a scene a certain way. In this master shot, Alex is shown being angry. There are more superimposed shots when information is revealed about his mother’s disappearances. The argument gets more heated, there are close ups of Alex, Katya and Mark. The camera stays focused on Katya’s reaction from her affair confessions. When Alex’s youngest sister Sarah, walks into the kitchen, she is ignorant about the situation. Sarah symbolizes the innocence in not knowing that her family are spies. Natalie, is Alex’s older sister whose boyfriend is a Russian spy, who works for the enemy in NYC. Natalie plays a vital role by bugging Alex’s cellphone and computer as a way to collect information from the CIA. The scene opens with Natalie and Viktor in bed, being woken up by a phone call from Rezident. Viktor is told that Alex is threatening his parents if they do not tell him the truth. There is parallel editing between the scenes when Alex confronts his parents, to Natalie and Viktor rushing into traffic, and there is a zoom in shot of Roman (main boss of Rezident), giving the order to assassinate the family to emphasize the point that he is in charge. After Viktor and Natalie stop the assault, there is a POV shot of Alex leaving the apartment in shock. The music was heavy, during the montage shoots and parallel editing emphasized. This shows how close Alex learned the truth, until his mother lied to him again. When the scene closes, everyone is safe but appalled with Katya’s romantic affair confession. The scene jump cuts, to Moscow a year before Operation: Black Dagger was put into play. The scene shows a conference that include white, European men who are wearing either professional suits or military uniforms. The audience is portrayed into knowing that these men have decision making power. This represents the Russian society, as sexist towards women because they are behind in providing them equality. The entire scene shows a man speaking to a large group about weakness in American economy. They are questioning United States power, because their only punishment is sanctions. Since American global influence is decreasing, Moscow feels they are at an advantage. However, one of the military officers disagrees with Black Dagger and calls it madness. But the speaker counters that remark with â€Å"Madness is American sanctions, madness is the last of Soviet sovereignty†. This scene represents politics by explaining the importance of those missing files. The missing files contain a plan that could potentially destroy American core values. This episode presents different beliefs and loyalties that result in conflict of interests. Nationalism influences decision making in different characters. In this series, women are used as pawns to satisfy a male’s needs. One of the many stereotypes portrayed about women in the workplace is a scene with Sam and Michelle played by Kenneth Choi and Floriana Lima. Sam questions Michelle’s place in the workplace to what she replies â€Å"Oh Sam, you have such a constrained view of me.† This shows that that even though she is a successful Hispanic women working in a male-dominated field of law enforcement, her supervisor will never see her as equal. Also, when Michelle is told to get a search warrant from the New York Attorney General’s office, Sam tells Alex to accompany her. Sam believes she will not get the warrant on her own. This represents what women face today in the workplace. There is a scene with Natalie and Viktor; that portrays Natalie through a stereotype that women in a relationship needs a man’s approval to feel complete and happy. This is a stereotypical image that presents women as being insecure about themselves. A women’s opinion is also disregarded because they are viewed as inferior. Katya’s advice got completely brushed off by Mark, who choose to go his way to the Brooklyn Navy Yard. When Katya had a gun in her hands, Mark looked at her in fear. This shows that he felt uncomfortable with a women who had power. The Allegiance characters embody certain traits that are correct in some cases. Alex O’Conner, the main protagonist represents being a hero, he is a smart CIA analyst with a promising future. His supervisor Sam, is trying to groom him for a better position but, also feels threatened by his talent. Special Agent Brock is the overseer of the organization, and does not like his authority questioned. Roman also does not like his authority to be questioned. They all feel that when they are questioned, they would be viewed as less than a man. For example, Roman needed to regain his control by killing Viktor’s friend, as a way to show dominance. Mark plays the husband role, so his decisions cannot be questioned by either Katya or Natalie. A scene that shows this power struggle is when Mark confronts Katya about the affair. When Katya says that she had to make a decision for the family, Mark puts her in an inferior that she is not one to make them. This show is great in cont ext, however when it comes to stereotypes Allegiance is a show to see. Allegiance exhibits an interesting storyline that shows the intertwining between politics and family matters. However, the characters role in the show present stereotypes that can put people in a box. This show unintentionally creates views to have a limited mindset of the real world.

Critical analysis of client care practices , innovation and pathways Research Paper

Critical analysis of client care practices , innovation and pathways for rewarding healthy and productive behaviour among senior - Research Paper Example This will assist to recommend possible improvement strategies which will energize the employees to achieve the organizational target. Introduction In modern organizations, worker motivation is an issue of significant concern to the human resource managers due to its close association with employee satisfaction. Consequently, global research has considerably paid attention to employee satisfaction strategies in different organizations (Aizcorbe, Moylan & Robbins, 2009: Arthur, 2000). The reason why worker motivation has garnered a lot of interest is because research has proven that satisfied workers are productive workers (Braganza, Awazu, & Desouza, 2009). Since employees form the labour resources in a business environment, there is need to seek optimal utilization of their skills and knowledge towards the development of organizational goals (Borzaga & Tortia, 2006). Different organizations adopt different employee reward strategies but the common objective is to align the employees to the business goals and objectives (Carl & Patton, 2001). In the health sector, employee satisfaction is important due to the great sacrifice that this sector requires given the existing shortage of working personnel in this sector (Damanpour, 1991: Hong Lu, While, & Barriball, 2005). Hence, rewarding productive staff, both junior and senior, would significantly increase their contribution to client service. The aim of this research is to investigate the staff reward strategies that Ghana university hospitals have employed to maintain a high morale among their staff. Both qualitative and quantitative surveys will be conducted to examine for this research to come up with research based conclusions and recommendations. Problem statement Lack of effective employee reward schemes in organizations limits the utilization of the labour resource in a business (Commongood Careers, 2008). Poorly motivated employees work for money and have their goals misaligned with the organizational goals . The shortage of medical personnel in the health sector requires that the few be optimally utilized to increase ensure that service delivery is efficient (Greene, 2009 : Gruneberg, 2001). Therefore, there is a need to employ innovative and dynamic motivational strategies in the health sector in order to ensure that employees drive both short term and long term goals of the organization to a success (Heskett, Sasser, & Schesinger, 1997). In Ghana, the ration of the patients to doctor ratio is high and hence efficient services can only be achieved if the employees are adequately motivated. The essence of this research paper is to evaluate the policies that have been put forward in Ghana University hospitals, and to provide recommendations to improve these policies. Objectives Main objectives To evaluate the innovation and pathways that public university hospitals of Ghana employ to reward healthy and productive behavior among senior and junior staff. Specific objectives To examine th e different criteria used to assess the productivity of a staff in Ghana university Hospitals. To examine the staff-reward mechanism that is used to reward productive employees in these hospitals. To examine the degree of employee satisfaction that has been achieved in these public hospitals. To establish the quality of service that has been ach

Women in the Second World War Essay Example | Topics and Well Written Essays - 500 words

Women in the Second World War - Essay Example This essay will compare and contrast the wartime experiences of these three great women. Therese Bonney achieved world fame as a photo journalist during the Second World War. She is greatly popular for her work which revealed the havocs of war on an innocent group of people. She initially acquired attention for her revelation of the war between Russia and Finland. Being the only correspondent who was there, she had the whole account to herself and was honored with the White Rose of Finland for her courage. Throughout the Second World War she toured all over western Europe capturing the miseries of the affected children in her photographs which she soon after included in her master work ‘Europe’s Children’. It was her objective to aid in building international ties between European populations, specifically the Americans and French. She also joined the Red Cross campaigns throughout France. She was grandly celebrated in the United States and Europe. Just like Bonney, Toni Frissell became a major female figure in photo journalism during the World War II. She voluntarily shared her photographic talents to the American Red Cross in 1941. Afterward she served the Eight Army Air Force and became the certified photo journalist of the Women’s Army Corps. She photographed a vast number of images of soldiers, nurses, and abandoned children for the services of the aforementioned organizations. Her moving pictures of African American air fighters and military women were employed to promote public support and sympathy for African-American and women in the service. Her only difference with Bonney is the extent of her fame. She is widely known locally but she did not achieve the same international fame that Bonney achieved. Meanwhile, a remarkable woman who became renowned during World War II, Janet Flanner, raised her name to the pedestal through writing. Janet

How far did the 'Bush Doctrine' constitute a radical shift in US Essay

How far did the 'Bush Doctrine' constitute a radical shift in US foreign policy - Essay Example A historical study is being attempted in this essay to bring out all the elements connected with American foreign policy and its relationship to other countries. Further, various elements of the foreign policy is analyzed here. It is seen that after the Second World War, the Cold War between USA and USSR contributed much to the formation of foreign policies in America. The two pillars of American policy at that time were deterrence and containment. After the fall of USSR in 1991, America became supreme power in the world. As a powerful nation it had to take clear cut foreign policies and the implementation of national security against the uprisings of different segments. But things changed soon. After 2000 America witnessed many damages on its national security. The attack on the Twin Towers and Pentagon on September 11, 2001 made America to think more about changing its foreign policy. The president of the time, George W. Bush expressed the need for the change of policy through his set of guidelines, commonly known as ‘Bush’s doctrine. His doctrine changed the foreign policy of America from deterrence and containment to pre-emptive action against the terrorists. The present essay tries to find out how the Bush’s doctrine acted as a great shift in the foreign policy of America. ... ‘America now commanded a degree of power greater than anything recorded in all of human history. No one doubted this; nor did anyone imagine that any other country or group of countries currently existed with the capacity, or the will, to challenge American power.’1 President Bush: His life, visions and Interests George W. Bush is the only President with an MBA in the history of America. He was born on July 6, 1946, in a political as well as business family in New Haven, Connecticut. Heron Marquez in the biography of George W. Bush says, that ‘His grandfather was Prescott Bush, a United states Senator from Connecticut. Other relatives were bankers and Wall Street stockbrokers.’2 His father was George Herbert Walker Bush, America’s 41st President. The background of politics has made him successful at politics along with business. In 1994 he made his entry into politics becoming the governor of Texas. The election for the president in 2000 made many str uggles for him. He was not supposed to be the president by the popular vote, but with the help of court he successfully became the 43rd president of America. In the election campaign Bush stressed the America’s foreign policy on maintaining peace. ‘He summarized his plans by saying, â€Å"I will renew the bond of trust between the American president and the American military. I will defend the American people against missiles and terror. I will begin creating the military of the next country.†3 The speeches of Bush during the campaign were mainly on the matters of American economy, education, and personal aspects. Even though much was not mentioned regarding the foreign policy he had clearly

English Language Mastery Essay Example | Topics and Well Written Essays - 500 words

English Language Mastery - Essay Example The out of class essays significantly helped me identify my strengths and weaknesses in the mastery of English language. When I was writing the two essays, I realized I could use some of the vocabularies that I had learnt in the course of my study. As featured in the essay on Inequality in America, I was able to use clearly and precisely words such as ‘perpetuate’, ‘rudimentary’ and ‘adamant’ among others. Such words, I did not have a slight idea of what they entailed. The same translates to the essay on The Effectiveness of Education in our Society. In addition, there was a clear mastery of sentence structuring. Initially, my sentences used to be lengthy and I used to receive comments that they were ‘ambiguous’. The use of speech marks has also been widely entrenched in my writings. I used to find it difficult to quote phrases from other sources and whenever I tried, there lacked coherence with the rest of my work. Through the essa ys, I was also able to perfect the art of writing an essay; this involves the arrangement of work into introduction, body and the conclusion. In addition, every beginning sentence of every paragraph had to carry a meaning that is explained in the rest of the paragraph.The in-class essay formed the foundation of my writing. These helped shape my skills such that the out of class assignments became easy to approach. There were myriad of challenges that I encountered through these assignments. Firstly, tenses were proving somehow challenging to master.
