The Scientific Study of Ecology - Essay Example By addressing and discussing these three specific issues, not only will we be able to gain valuable information on these particular matters but on the subject of ecology as a whole. This is what will be dissertated in the following. In ecology terms, the carrying capacity of a population refers to the supportable population of an organism, and this is taking into consideration the vital factors such as food, habitat, water, and so on. There is strict mathematics involved with the carrying capacity issue, and depending on the particular situation, the impact of famine, for instance, could be quite moderate or extreme. In terms of what the possibilities are for the continued growth of a population once it has approached its carrying capacity, this really depends on the particular population being discussed, but it is very important either way here to understand that â€Å"Algorithms for estimating the carrying capacity of areas provide wildlife managers with important information for understanding and managing populations†¦The energy-based carrying capacity of an area varies with the energy required by a wildlife population and the energy available in foods in the area.† (29). In response to the issue of what process would be necessary in order to allow a population to be established and thrive in an ecological community, basically, there are several different factors that need to be taken into consideration here. In all reality, the most classical explanation is that all species are able to coexist, as long as they are â€Å"sufficiently different in their ‘niches’, the particular habitats or conditions in which they thrive or in the resources they exploit, and have corresponding weaknesses in other areas, so that no one species is able to out-compete the others.† (67).  

The Countrys Of Production Possibility Curve Economics Essay

The Countrys Of Production Possibility Curve Economics Essay (B) Assuming that the country is currently producing 40 units of goods and 70 units of services , what is opportunity cost of producing another 10 units of goods? 70-65=5units services opportunity cost (C)Explain how the figures illustrate the principle of increasing opportunity cost. Opportunity cost is the best alternative give up for the chosen option. This means without cost cannot make any decision. It also can describe as relation between choices and scarcity. The scarcity is come from factor of production is include labour, land capital and entrepreneur because it is limited resource. Therefore, we need make a choice to get a good product and giving up other product to fulfill. In the figure 1.1, company produces services and goods. In point A order to produce 80 units of services and the goods is 0 units, because the company must use all their resource in producing services. The company produces 10 units of goods and 79 units of services. The increase of goods is 10 units therefore company need to give up 1 unit of services to produce goods because no enough resource to make it. In point b, if the company wants to produce 40 unit of goods, the company could only produce 70 units of services due to the scarcity of resource. In point C, the company has already utilized all the resources in produce 100 units of goods, therefore, the company will have no other resource to produce services in the market. According to figure 1.1, point A, B, and C are the most efficiency allocation of resource in production possibility curve. Point G and F are not efficiency allocation of resource. Point G is the impossible points to produce the output, because the company didnt have enough resource such as labour, land, capital and entrepreneur to produce output. Point F is a wastage of resource, because the company no plan well. For example, Samsung Company produces LCD television and radio. When each additional produce LCD television, Samsung Company will give up produce radio and increase the sales of LCD television, because the resources are limited. When the Samsung Company used all resource to produce LCD television, Samsung Company fully give up produce radio. When increasing produce 10 units of LCD television, Samsung Company will decrease 10 units of radio for the additional producing 10 units of LCD television. So, the opportunity cost is 10 units of radio. (D)Now assume that technical progress leads to a per cent increase in the output of goods for any given amount of resources. Draw the new production possibility curve. How has the opportunity cost of producing extra units of services altered? Table goods and services: Units of goods 0 11 22 33 44 55 66 77 88 99 110 Units of services 80 79 77 74 70 65 58 48 35 19 0 In the figure 1.2, company increase 10 per cent in the output of goods. If the company utilized all the resources to produce goods, maximum units of goods can been produce increase to 110 units. When the company increases producing units of services from 0 to 19 units, units of goods can be produce decrease from 110 to 99 units. That means, the opportunity cost is 11 (110-99=11). While the company increases producing units of services from 19 to 35 units, units of goods can be produce decrease from 99 to 88 units because the resource not enough to produce more than that amount of goods and the rest. That means, opportunity cost is 11 (99-88=11). From the figure 1.2, the opportunity cost of producing extra units of services is constants at 11 units. Example, Sony Company produces camera and android hand phone. In long term, market have potential to increase the unit android phone ,therefore each additional produce android, Sony Company will give up produce camera and increase to produce of android hand phone , because the factor of production are limited. According to NEXUS PRO ECONOMI ASAS by Theng Kock Leing, the opportunity cost can be defined which 2 alternative goods and services when each goods produce must give up some services. 2(A) What are the equilibrium price and quantity? Equilibrium price: RM5 Equilibrium quantity: 12 millions (B)Assume that changes in fashion cause the demand for t-shirts to rise by 4 million at each price. What will be the new equilibrium price and quantity? Has equilibrium quantity risen as much the rise in demand? Explain why or why not. Demand is defined as a consumer desires to own and willingness to buy some goods and services at suitable price and time. Demand also can define as a consumer willing buy and pay for the goods and services. Willingness to get some goods and services without the ability to pay not defined as demand. For example, MR LEE want to buy Proton Saga but he dont have ability to pay the money therefore this is calling willingness not call demand. On the other hand, if MR LEE has the ability to pay the price of car then the willingness MR LEE will become demand. Supply is defined as quantity of goods and services willingness and ability to supply or produce by firm at a suitable price and time set by the consumer. Price will affect quantity supply by consumer because different price will supply different quantity. Supply goods and services will affect by certain period of time. When the changed of certain period of time, supply of goods and services will be changed. According to law of demand, while the price of goods and services increase will affect the quantity of demand decrease assume Ceteris Paribus. On the other hand, the price of goods and services decrease will affect the quantity of demand increase therefore the relationship of price and quantity is negative. According law of supply, while the price of goods and services increase will affect the quantity of supply decrease assume Ceteris Paribus. On the other hand, the price of goods and services decrease will affect the quantity of supply increase therefore the relationship of price is positive. When the demand for t-shirts rise by 4 million, the new equilibrium price is RM6 and the new equilibrium quantity are 14 units. The equilibrium quantity is rise to 14 units from 12 units as rise in demand. When quantity of demand t-shirts rise 4 million, the quantity demand curve shift to right with the quantity supply fix. With the increasing in quantity demand, quantity demand is more that quantity supply at the equilibrium price at RM5. The firm will increase the price of t-shirts from RM5 to RM6 to decrease the excess demand. The new equilibrium will achieve at price RM6 and quantity 14 units of t-shirts. With the quantity supply fix and the changing of quantity demand will make the price and quantity change. As the conclusion, the initial equilibrium price RM5 will change to RM6 and the equilibrium quantity increase from 12 units to 14 units as the increase quantity demand. (C) Now plot the data in the table and mark the equilibrium. Also plot the new data corresponding to (B) Price(RM) 8 7 6 5 4 3 2 1 Quantity demanded 6 8 10 12 14 16 18 20 Quantity supplied 18 16 14 12 10 8 6 4 New quantity of demand Price(RM) 8 7 6 5 4 3 2 1 Quantity demanded 10 12 14 16 18 20 22 24 Quantity supplied 18 16 14 12 10 8 6 4

Symbolism in the Loss of Light in Macbeth :: essays research papers

'Light' symbolizes truth, goodness, awareness, innocence and purity, everything linked to positive attributes. Light can represent anything Godly and saintly. ‘Darkness’ is the opposite of light. It symbolizes evil, unawareness, mischief, blindness and treachery. Firstly, both the murders of King Duncan and Banquo are committed at night, when the sun has set and darkness has fallen. Furthermore, when Lady Macbeth plots the murder of King Duncan she calls the â€Å"thick night† to â€Å"pall† â€Å"in the dunnest smoke of Hell† to hide her actions. She depends on the darkness to carry out the sinister deed. In addition, before and after the murder, there is much mention of nocturnal animals, for example, how the â€Å"owls shriek’d† and the â€Å"crickets cry†. Macbeth also tells the stars to â€Å"hide their fire†, which shows a reference to one of King Duncan’s lines when he mentions that â€Å"the signs of nobility are like stars†. Therefore Macbeth wants to hide the light when he does the deed. After the murder of King Duncan, Ross speaks to an old man about it, and of how the â€Å"dark Night strangles the traveling lamp†. He also mentions â€Å"Night’s predominance† over â€Å"the Day’s shame†. He probably thinks that the loss of Duncan equates to loss of everything ‘proper’, since he speaks of strange happenings, like horses eating their own kind. This displays a state of chaos and unawareness which is linked to darkness. Towards the end of Act 3 scene 2, Macbeth speaks of his plan to kill Banquo, and he then calls the â€Å"sealing Night (to) scarf up the tender eye of pitiful day†. He also mentions that the â€Å"Good things of day begin to droop and drowse / Whiles Night’s black agents to their preys do rouse†, which yet again makes a reference to nocturnal animals (preys). It also shows darkness taking over light, or in this case, Macbeth’s evil plot to get rid of the â€Å"worthy Banquo†.

Sports Event in School

Sport events in our school Sports are very important in everyone’s life as they give pleasure, health, discipline, happiness, self-control and sporting spirit. Sports can learn students’ physical co-ordination and social lessons about winning and losing. There is a well-known proverb â€Å"All works and no play make Jack a dull boy†. It is full of wisdom. After the day’s work in class, students need some healthy recreation to refresh their minds. Education without sports is really incomplete. So, sports are important in every school for clever and healthy students.They are several kinds of sports some are outdoor and some are indoor. In our school, the schoolboys play football, volleyball, basketball, table -tennis, chess, and so on. The school playground is no less important than the school lessons. It is on the playground that we learn to face defeat with a smiling face. So, the school playground helps the students to fight the battle of life like brave soldiers and heroes. Our school has two playgrounds to play football and two for playing basketball. There will be tournaments to play football in every Grade from Grade-4 to Grade-11.There is an each team in every section and so if there are six sections in Grade-9, there will be six teams and a tournament is held until there are two teams to pay the final match. All schoolboys look active and alert with their team track-suit. There are also tournaments to play each sport. Teachers in charge will take care of their pupils in playground during tournament. They give them fresh limes and purified drinking water. The red-cross schoolboys and teachers are ready to help the injured players. The Headmaster will give the prize to the winners and the champion team who gets the first prize will take a group photograph.In January, there are interschool sports competitions that include track and field sports such as running, jumping and throwing events. The running events are sprints, middle d istance races, long distance races, hurdle and relay races. The jumping events are high jump and pole vault. The throwing events are short put, discus and javelin. Team sports can be played by two teams. A team has been organized with some players. They must have team-spirit and they fight the rival team collectively. Thus team sports make one less selfish. They know the value of team work and playing together makes them friendlier.A player must have stamina and be patient. He must not easily down-hearted. If the players of one team become excited, they may lose their chance. The carelessness of one may make the team defeated. So, players are inspired team-spirit by playing team sports. A true sportsman never thinks of winning the sports by hook or by crook. He never wins victory by foul play and we know that â€Å"Honesty is the best policy†. So team sports are essential to health, happiness, progress and unity. We gain a lot of benefits from playing sport events and student s should take part in these sport events.

Freedom of Speech: Abused from Abroad Essay

The constitution was designed to protect us from tyranny and abuse by government and dictators. Our policies need to protect us from those that would slander a segment or our population. Foreign hate groups direct their views to those protected by the same document that affords them their right to post. Freedom of Speech: Abused from Abroad The first amendment protects the rights of Americans to have free speech even if that speech is hate speech but it should not be used to protect foreign hate speech just because it is hosted on an American server. The First Amendment really does distinguish the U. S. not just from Canada but from the rest of the Western world. (Liptak, 2008) Given the nearly unanimous international institution of regulations restricting online hate speech, the United States stands alone in its support of free speech—including Internet hate speech. (Breckheimer, 2011) These are good examples of our first amendment and how it is perceived across the globe. We are known for our liberal view of free speech protections and based on our history of oppression by monarchs and the purpose for us to seek a new land to call our own it fits our nation well to have such an amendment in place to protect the rights of our citizens. I feel that this very right is being abused by foreign hate groups who not only direct their rhetoric towards others in their own countries but also towards U. S. Citizens who are being protected by the very document that allows them to be harassed from afar. Many countries that we consider our allies have laws that prohibit hate speech and they level severe penalties upon those who break these laws. I support the right to free speech for every American as accorded by the first amendment. I do not support providing that same right to those who are not Americans and do not hold themselves to the same values that we Americans hold ourselves to. Free speech is just one of the things that make Americans unique in the world. To claim the right of first amendment free speech you need to be an American citizen. Our first amendment was not meant to be used as a shield for foreign dissidents wishing to bypass their countries laws. As a world citizen the United States needs to make certain that we respect each country for it rules and regulations as we would wish them to respect ours. We need to change our foreign policy to reflect the fact that our constitution was meant for Americans and not for the world. To allow foreign groups to host their messages on our servers even if we agree with their message shows that we as a nation do not respect the governing body of the nation and it’s laws. We should be extra vigilant to protect our citizens from the ranting’s of foreign hate groups. The first amendment was meant to protect the citizens of the United States and not those wishing to belittle and malign its citizens. Paul Przybylski wrote that because many servers, and especially those that spread hate speech content, are stationed within the United States, any solution without U.

Abington School vs. Schempp essays

Abington School vs. Schempp essays Abington School District vs. Schempp In 1949, a state-wide law was passed in Pennsylvania that required public school students to read scriptures from the Bible and recite the Lords Prayer everyday in class. This law stayed intact until Edward Schempp challenged it nine years later. Pennsylvania wasnt the first or the only state to enforce law making it mandatory for students to read from the Bible during school. Twenty-five additional states had laws allowing optional reading for the Bible. But in eleven of the twenty-five states, courts had decided those laws were unconstitutional. Mr. Schempp took the case to court in to 1958, claiming that required reading for the Bible and recitation of the Lords Pray prohibited free exercise of religion for his children, and was therefore unconstitutional, under the First Amendment. Mr. Schempp son, Ellory, stated under oath, that he didnt not believe in Jesus Christ, or the Christian beliefs. He testified that ideas opposing to his were presented to him while he was at school in Abington High. He received punishment because he refused to stand at attention during the recitation of the Lords Prayer and when requested to leave during the exercise, his demands were denied. One of the greatest witnesses was Rabbi Dr. Solomon Grayzel. Dr. Grayzel explained the psychological harm that could come from reading the New Testament without explanation. The context of the New Testament, without explanation of the work, had caused grievances in Jewish children while in similar required situations. This also came to show that if a Jewish child could be offended and upset by the Bible reading, any child of a family rejecting the principles of the Trinity and Jesus Christ would be equally offended, to the point that reading the Bible could be considered blasphemous. In argument for the recitation of the Lords Prayer, they ...
