Ecosystem Succession Paper - Essay Example These areas are places that have been damaged by destructive events, such as fires, and have been cleared of existing vegetation, such as trees. 1b. Biotic components are the living things that form the environment, such as predators, while abiotic components are the non-living things in an organism’s environment, such as temperature and light. These components can change the equilibrium of the ecosystem in the sense that the ecosystem can only function as a whole, and not in parts (â€Å"Biotic†). The biotic components of an environment, whether they be prey or predator, factors into what organisms are currently dwelling in that area and which one is the dominating species. If a certain species were to become endangered or extinct, the ecosystem would be thrown off-balance as it would now be missing both a predator and a prey. Furthermore, if the abiotic factors change, damage can also be done to the ecosystem. If the temperature in a hot, dry area suddenly changes to cold and wet, the organisms that have grown accustomed to the hot climate will not be able to strive with the changes, as they were not created to tolerate it. These factors will greatly, and negatively, affect the biotic factors, throwing off the entire ecosystem. If the ecosystem is not balanced, it cannot survive. 2b. The natural cycle of progression in an ecosystem involves the need for things to grow and then die so that new life can feed off the old life (BioScience). The old organisms need to give way to allow new organisms – whether they are of the same species or not – to grow and to strive. Just as with any aspect of any life, life comes from death; it strives off of what was previously there and makes a new environment for itself. If a new organism appears, it can offer new environmental components to its surroundings. 3b. Some of the mechanisms that can help an ecosystem’s recovery from a

Liberal Arts Studies - Essay Example It is reasonable to see corporations and communities as benefiting from the struggle and competition that Darwin saw in the animal world and applied to humans as well. With a new job opening, for example, candidates will be determined as qualified or unqualified. The qualified applicants will get the interview for the chance to prove that they are up to the task and capable of doing what is required. Ideally, the best (or strongest) candidate based on the job description will be hired for the job. However, in the business world this is not always the case. Often the person hiring for the job will hire someone based on their personality or if they know them personally. So the most qualified or strongest applicant often does not get the job. However, ideally, a smart business person would hire the strongest and best qualified candidate. In modern society, certain jobs have been reduced or even eliminated. With the growth of technology, many professions were reduced in number while new professions were created. There are numerous examples of people who are professionals making a lot of money who are laid off and find themselves out of work and unable to get another job.

Effective Teaching Strategies for Students with ADHD Essay Example for Free

Effective Teaching Strategies for Students with ADHD Essay 1. What is the purpose of the study? To share methods of intervention for students with ADHD. 2. When was the study done? 2011 3. Who did the study? George DuPaul 4. What are the research question and hypotheses (if any)? Which school-based intervention strategies are the most effective? Hypothesis: Multiple treatment strategies implemented consistently across multiple years will improve success for students with ADHD. 5. Does the literature background support the need for the study? Please explain your answer. The background literature defines ADHD, explains that these students have issues with retention, attendance and standardized tests. This information provides justification for exploring the topic of effective interventions. 6. What are the variables under study? Identify them as independent, dependent, moderator, control. The independent variables are ADHD and the dependent variable is 7. What is the setting, sample, population? 8. Identify the type of research. Descriptive, non-experimental. 9. What statistical procedures are used, if any? None were used. 10. What kind of design was used? Is it appropriate to the stated purpose, research questions and hypotheses? Since this is a descriptive article, it does not apply any research design nor does it explain the basis of selecting the particular â€Å"effective† strategies. The provision of several strategies does, however provide a variety of effective strategies to implement, which supports the opening statement, that it takes consistent implementation of multiple effective strategies for successful intervention with ADHD students. 11. What are the findings of the study? As stated above, the study impresses that it takes consistent implementation of multiple effective strategies for successful intervention with ADHD students. 12. Are there any problems with the internal validity of this study? The fact that the students are from a socioeconomically disadvantaged background and that the control and experimental groups were selected at random increases my confidence that there is internal validity. 13. Are there any problems with the external validity of this study? It is not possible to say that this study necessarily applies to the population because it was only conducted in one classroom. If there was a more robust sample from a variety of schools I would feel more confident applying this to the whole population in general. 14. What can be validly concluded from this study? The fact that there is no explanation for the choices that were made for â€Å"effective† strategies leads me to say that this paper is merely descriptive of options, not necessarily of the most effective interventions for ADHD.

Napoleon Essay -- essays research papers

During rough times in France in the late 1700’s, an anarchy was being formed. A revolution turned into civil war and the people were unhappy and needed a leader. At this time, General Napoleon Bonaparte took an opportunity. Napoleon’s fame for winning battles in the Middle East and Egypt and crushing royalist uprisings back at home allowed him to take over the Directory with ease. Recognized for his great military skills and outstanding leadership, Napoleon easily won over the hearts of the people.  Ã‚  Ã‚  Ã‚  Ã‚  Napoleon’s first move was to obtain leadership. With the help of Pope Pius VII Napoleon was named First Consul of France. Though France was now declared an empire, it was technically a Republic because of the set Constitution. Through this Constitution, Napoleon set up a system of government that helped settle the disputes of France. Napoleon’s career was arranged into a series of both accomplishments and defeats. He demonstrated his accomplishments during battle as well as in government. By setting up the Napoleonic code, Napoleon unified the old Feudal Law and Royal Laws. Many of the laws set up, were based on his knowledge of the Enlightenment. He simplified the laws of old as well as new, and allowed freedom of speech and press. His main idea with these laws was to give all men equal rights. Women were also included into several laws. Another accomplishment was shown through religion. Though he supported Cat...

Living In a Concentration Camp As a Jew

Living In a Concentration Camp As a Jew By: Sheena Xu Auschwitz was the largest concentration camp to created by the German Nazis in April 1940. It was located by a town called O?wi?cim, Poland. It was one of the most dangerous Nazi camps and was called the â€Å"final solution†. 1, 095, 000 Jewish men, women, and children were deported to Auschwitz and 960 000 died intotal at the camp. Auschwitz was divided into 3 sections. One was a prison camp, one was used as a killing and extermination center, and lastly there was a forced labour camp. Only about 11% of children who were still alive in 1933 had survived the Holocaust. The prisoners had 3 small meals a day. Breakfast was half a litre of imitation coffee or a herbal â€Å"tea† which was always unsweetened. Lunch was a litre of watery soup and you would be considered lucky to have a few pieces of turnip or potato peel, and many newcomers had a difficult time eating it. The evening dinners were around 300 grams of black bread with either sausage, margarine, marmalade, or cheese on top. It had to last until the morning so prisoners would hide it somewhere while they slept, but the starving prisoners would usually eat it all right away. Prisoners had many duties both inside and outside of camp like working in factories, farms, and coal mines. Work was every day except Sunday and they woke up at 4:30 in the summertime and at 5:30 in the wintertime and the nighttime silence was at 9:00. They worked for German companies and were used as slave-labour. The Sonderkommando were Jews selected for their strength and fitness to work in the crematoria. Their job was to dispose of dead corpses coming from the gas chambers. The Kanada Kommando was another job where prisoners were assigned to sort through the valuables of Jewish people so they could be sent back to Germany. Canada was a country that symbolizes wealth to the prisoners, so that's why they named it Kanada because of all the clothing and jewelry. Anyone who worked for the Kanada Kommando had much better living spaces in barracks than the other prisoners, but if they were caught stealing anything, they would be killed.Doing anything wrong or not to the standards could be risking your life. Most prisoners were sent to the gas chambers immediately after arriving. Different punishments they would use was the â€Å"post† or flogging. The â€Å"post† was where you're hung in the air for a long time, so your arms become paralyzed and you are sent to the gas chambers because of being unfit for work. Flogging is when a prisoner is bent over a stool with their arms stretched forward and they would be whipped for about 25 times. A hanging would take place during roll call and it was meant to intimidate other prisoners. A shooting was where prisoners had to strip naked and they were shot in the back of the head. Smoking, relieving yourself at the wrong time, or attempting suicide meant punishment or death. On January 27, 1945, the Soviet Union soldiers had liberated the remaining prisoners from Auschwitz. Intotal, 135, 000 Jewish prisoners were liberated but most died soon after. Many relief workers and physicians tried to save the prisoners but many were too weak to digest food and they couldn't be saved. Since they had gone without food for so long, the food was too rich for the prisoners, so they had to eat little by little. Even though so many had died, there were still those who fought to survive, and they are the people that could still live to tell their story.

Organisational Structure of Nike Company Free Essay Example, 1500 words

Nike has a flatter horizontal hierarchical distribution of functions thus effectively facilitating the democratic decision-making process within the organization. Integration refers to coordination among a number of departments. Thus it s clear that differentiation effectively refers to various costs that are associated with bureaucracy. For example, the amount of time spent at meetings between decision makers and subordinates can be regarded as the ultimate outcome of differentiation and integration of functions and tasks. Nike s own decentralized organizational structure places emphasis on the efficacy of decision making. Therefore its organizational structure doesn t necessarily hinder decision-making functions at the organizational level. Similarly, Nike s organizational structure is highly characterized by a delegation of powers, authority, and responsibility to junior managers whose decision-making capabilities are tested on a regular basis. Departmental heads have sufficientl y delegated powers and authority to subordinates with a view to enlisting the support of the latter to achieve long term organizational goals (Hatch and Ann, 2006). Despite the ever-growing size of the company, Nike has managed to identify issues related to motivation of employees with extraordinary success thus creating a harmonious work environment within (Frenkel, 2001).
