Eutrophication
Eutrophication is the process by which a body of water becomes rich in dissolved nutrients from fertilizers or sewage, thereby encouraging the growth and decomposition of oxygen-depleting plant life and resulting in harm to other organisms (Encarta dictionary 2007). This is one of the ecological problems that are affecting PAU thought others don’t see it as a problem. Thus, the essay will discuss further on how it is started and evidences of its existence, how to minimize or prevent it from eventuating, and how it affects the environment in which we live in and give a real case study of its effects.
Eutrophication began to develop on the lakes of PAU when the campus department stopped cleaning the lakes in order to let the birds to lay their eggs on the flowers growing in the lakes. This is evident in lake two. This has led to eutrophication due to the overcrowding of plant life in the lakes. Some proof that the lakes are becoming entropic are that they smell, overgrowth of plants means the level of oxygen is depleted and less penetration of sunlight, algae are starting to cover the surface of the lakes. Therefore, this shows that lakes here at PAU are starting to become eutropic.
Prevention is better than cure therefore it is better to prevent the lakes from becoming eutropic than to cure it after it has become eutropic. As stated in the article, ‘How to cure Eutrophication’ (2012, May 17) that a pond that has become eutropic is hard to rehabilitate. This is because not only will you have to fight the nutrients that are currently running off into the pond, but you also have to undo all of the problems that have compounded over the past number of weeks, months, years. By this point, the nutrient load has been built to astronomical proportions, and it will certainly take some time for the pond to return to the state of a balanced ecosystem.
Hence, it is better to prevent eutrophication from eventuating by cleaning the lakes thoroughly. The lakes at present have a lot of decaying matter at the bottom. So it would be a good idea to clean that and a little on top of the surface so as not to destroy the birds nest but to control the growth of plant life on the surface.
There are many problems that are associated with eutrophication. Problems that affect us humans and the ecosystem upon which the plant and animals live and depend on. Problems that we humans would face is the foul smell that would be produced and the stale and decaying organisms in the lakes. A similar problem eventuated in London (England) along the delta of river Thames in 1848. The delta of river Thames became eutropic because of the huge amounts of sewage disposed into it. This caused large growth of plant life near the river and therefore causing the river to become slightly stagnant, slowing the flow of sewage to the ocean. And so the fish in the river began to die as a result of this sewage problem. The eutrophication caused by the sewage had a greater impact on the people of London. The cities near the river Thames were most affected by the foul smell, which some business were shut down because they could not take enough of the smell.
It was not until the year 1850 when the engineer Joseph bazelgette Eutrophication is a dangerous, unhealthy, and extremely unsightly state for your pond. Once a pond reaches this point, it can take years to rehabilitate it to the point that it can sustain life again. Eutrophication: Stop it Before it Starts

Snakes in Suits: When Psychopaths Go to Work Article Summary

...Snakes Suits When Psychopaths Go To Work Book Review by Antoinette Foster-Shaw EDD 9100 Leadership Nova Southeastern University April 19, 2011 1 Snakes in Suits: When Psychopaths Go To Work (2007) is a compelling and realistic book that openly discusses corporate psychopaths. This book also helps the reader go beyond the stereotypes placed on psychopaths. The authors are two psychologist; Dr. Robert Babiak and and Dr. Robert Hare who both have performed extensive research in psychopathy. These authors have displayed how psychopaths slither not only their way into people’s personal lives but also the workforce with devious methods and strategies. The main tool of a psychopath is disarming charisma with the lack of empathy, remorse, and shame. Their mind is constantly searching for angles to start the games of deceit. They also represent confidence, strength, calmness, and always seem right for the job offered. Assessment, manipulation, abandonment, and ascension are the phases of psychopathic behavior which are concisely explained in very simple terms for easy understanding. The phases enable the reader to clearly understand each phase that is relevant in a psychopath’s process towards their main goals of accomplishment. The authors have clearly......

Semantic Role In Language

...semantic role is a relationship that a participant has with the main verb in the clause. While syntactic analysis focuses on sentences and all the function words in a sentence, the semantic analysis focuses primarily on meaning, i.e. on the proposition expressed in a sentence. A proposition is meaningful and it can be expressed either in different sentences or in parts of sentences. In order to do semantic analysis, we have to distinguish inflection from a proposition. (Kreidler,46) For example: 1a Linda bought a shirt to her mother. 2a Linda buys a shirt to her mother. These two sentences have the same proposition, i.e. Linda, buy, shirt, and mother. In the first sentence, we see that past tense is added to the proposition; while in the...

Drover's Wife

...readers about problems that the drover’s wife met and she tried to deal with without husband’s assistance. One day, there was a snake in the house. To protect her children, she stayed awake all night to guard her children while her children were sleeping on the table in the kitchen. At the end, she and her snake-dog killed snake and burnt it in the next morning. Among all characters represented in the story, I am interested in Drover’s wife the most for three main reasons. First, she was a clever and patient woman, for the fact that she had fought all difficult tasks without husband’s help. For example, she was used to being left alone because after she married to drover, they met drought of eighteen months that made her husband leave home. Therefore, she did all tasks in family such as looking after cows, taking care children and so on. She is also bright because during snake in her house it was sunset and thunderstorm was coming. She could not stand outside her house, and then she quickly decided to pick up several armfuls of firewood into kitchen and took her children there. Finally she made table in kitchen as bed for children sleep. Second, she was not only a protective wife but also a good wife because one day after there was snake in her house, all night long, she kept her eyes open wide to make sure that her children were safe and the snake would not bite her children. She also neither complained about living condition nor her husband’s absence, but she worried......

Religious Symbolism in Sweat

...“Sweat” by Zora Neale Hurston is filled with many religious symbolism. Good versus evil plays a large role in the development of Delia and Skype Jones, as characters. The story is about Delia, an African American woman who is a washwoman for whites. Delia consistently looks to her religion for guidance and support as she endures the many hardships that she faces because, which are caused by her abusive husband and unfaithful husband, Sykes. Delia and Sykes Jones is a couple that have opposite moral values, but yet they are tied together through marital vows, that no longer have much importance or value. Delia Jones is portrayed as the Protagonist and a very modest woman of weakness who later gains the strength to stand u to her abusive husband Skyes. Delia looks to God and her religion to help her build the strength she needs, so she can continue to be protected from her husband who is both physically and emotionally abusive to her. However, Sykes Jones, is every bit the opposite of Delia Jones. He has neither religious values nor any important moral standards. He is an adulterous, who takes Delia’s hard working money, and spends not on his wife but on his mistress Bertha. Delia who relies solely on her faith and continues to stay contempt, no matter how her husband treats her, but Delia warned him that in the end, Sykes “sometime or ruther, Sykes, like everybody else, is gointer reap his sowing (par. 26).” The white clothes that Delia washes are a symbol of......

Toxicology

...Snakebites are often treated by administering specific “anti-venom”. Explain how “anti-venom” may work. Snakes are cold blooded animals that are found in tropical and subtropical countries. Snakes have some glands in their mouth that produce very poisonous substance and its even worst through their bites. The seriousness or extend of the poison depends on various factors. One is the body tissue where the venom is injected. It’s more serious when the poison is injected directly to the blood vessels meaning it spreads very quickly through blood transmission in the rest of the body. The extent of the poison also depends on the part of the body where the snake bites. Snake bites that occur on parts of the body with a lot of adipose tissue are less poisonous than in the parts with less adipose tissue. This is because these tissues are low in blood supply hence they end up delaying transmission or the spread of poison to the rest of the body (Timbrell, 2009) Specific anti-venom is used in treating snake bite since the severity of the poison depends on the snake type and other factors. Since the venom is injected in the blood the anti-venom should also be administered to the blood In order to neutralize the poison. This means that it might have some side effects if not well used since its injected directly to the blood. The anti-venom neutralizes the poisonous venom injected by the snake hence causing venom release from the receptor site. Since venom causes blockage of these......

The Closing Door

...In Angelina Weld Grimke’s “The Closing Door”, Jessie Redmon Fauset’s “The Sleeper Wakes”, and Zora Neale Hurston’s “Sweat”, the roles most often appear to have men as dominant, or in charge, figures. However, the typical view of the male figure being dominant and the female being submissive may not be quite as distinct in the above three texts, as first thought. It is even possible that the roles of the dominant and submissive parts are actually switched. The following will show how both the male/female and dominant/submissive combinations may be interchangeable, depending on which aspects are considered. In the stories “The Closing Door”, “The Sleeper Wakes”, and “Sweat”, male figures appear to be the ones that are in control, or dominant, in the situations. The women take direction from men. Throughout their stories it is pervasive that society is male dominated. Although there are many similarities between the stories in this regard, some of the differences are due to social, economic, physical, and moral divisions. These divisions, or aspects, become important in how one may look at domination in these stories. In the story “The Closing Door” by Angelina Weld Grimke, the two divisions that become important in respect to who controls things are physical and economic. Grimke describes the male character, Jim Milton, as being a “brown, good-natured giant” and also “He would reach her, it seemed, in one stride and would pick her up bodily, apron, money and all” (Grimke......

Macbeth

...imagery of unnatural birth, animal motifs, and the actions of Macbeth. Throughout Macbeth, images of unnatural births help fuel an unnatural atmosphere. In act four the witches brew up a potion consisting of different parts of living things. One of those things is a “Finger of birth-strangled babe/ Ditch-delivered by a drab” (IV,i,30-31). This contributes to the atmosphere of the play because during the Elizabethan time period, grueling births were not common. The fact that a prostitute gives birth to a baby on the side of the road, foreshadows that the baby will bring evil upon society; ultimately creating an unnatural and eerie atmosphere. Also, the fact that Macduff is “…from his mother’s womb/ Untimely ripped” (V,viii,15-16) plays a role as to how an unnatural atmosphere comes about. Imagery of Macduff’s birth causes a dark and unnatural atmosphere. Macduff is born from a sea section because Shakespeare tries to appeal to the senses of the crowd. Sea sections were not commonly used during the Elizabethan era. The dark image created by Shakespeare goes a long way to create an unnatural and dark atmosphere. Unnatural births were a sign of the devil and were deeply frowned upon during the Elizabethan time period. Lastly, the third apparition is a child crowned with a tree in his hand. The apparition confuses Macbeth...

Pompeii and Herculaneum

...aspects of ones life, and ones family. A number of sources both written and archaeological have provided today’s society with facts and evidence of the household Gods and foreign cults in Pompeii and Herculaneum. The home played a vital role in Pompeian religion, as it was “the most sacred..hallowed place on earth” of every citizen in the city. The household gods also known as the guardian spirits of the family, called the Lares were the central factor of household religious practices in Pompeii. Every home incorporated a shrine dedicated to the Lares, the Lararium which was a mini-temple of sorts that housed the statues or painted images of the Lares. These Lararia were usually set in the Atrium, though others have also been found near the kitchens and in the gardens. Source 1 shows a lararium found in The House of the Vetti, this provides an example of what these household shrines were like. In Source 1, there are the Lares surrounding the paterfamilias above a snake. The Lares themselves represent the spirits that guard the family. The paterfamilias, the central figure, is the leader of the family who carries out the religious practices. The snake beneath is believed to be the protector of the household, genius loci. The role of the snake was to keep vermin away from food sources. The continuous occurrence of lararia and Lares in the houses of Pompeii and Herculaneum provides itself as evidence of strong values of religion in the home. Source 2 is a picture...

...traditional religion, but rather worshipped with poisonous snakes. Veronica argued her 1st Amendment rights to worship with poisonous snakes should be protected just like the 1st Amendment guarantees protection for other religions & the right for people to own guns. Her argument was the state should have never violated her religious practices. As judge or citizen, I can honestly say I have never heard of such faith & snakes scare the absolute hell out of me. There ain’t gonna be no snake worshipping in my town – judgment DENIED!” 1. Veronica’s beliefs may seem unusual but it still counts as a religion regardless whether you have heard of it or not. The establishment clause states that all religion must be read the same. The judge’s ruling is incorrect, especially because he/she is afraid of snakes and has never heard of these practices before. However, judge’s ruling would make more sense of he/she focused on dangers of poisonous snakes, since they have the ability to kill. If there is a possibility of snakes causing harm, then it would be rational to curtail that religion. For instance, religious extremists are not allowed to act on terrorism/violence, despite what their religion may preach... you cannot stone a woman to death simply because she cheated on you. In other words, there is a difference between practicing your religion and causing damage by your religion. You can control a gun, but not a venomous snake. “The next case involved an elected official......

Phobias

...an irrational fear. Belief that a phobia is not the same as a fear is controversial. This is increasingly important in this age of advanced psychology, medicine, and technology. Many people think that a phobia is defined as having a fear of a certain stimuli, but seem to overlook the fact that a phobia is more than a fear it is a psychological disorder. Phobias are quite difficult to understand, even to a person who has one. A phobia is an unrealistic and disproportionate fear of a certain stimuli resulting in panic, severe anxiety, lack of control and impairment. Phobias can be classified into two main groups, simple specific and complex general. Simple specific phobias are defined as an irrational fear to one specific stimulus, like a snake for example. People with this type of phobia only react to that one thing, and the reaction only results when the certain stimulus is encountered. Some examples of simple specific phobias are emetaphobia, the fear of vomiting, arachnophobia, the fear of spiders, and astraphobia, the fear of thunder and lightning. On the other side, complex general phobias result from situations, not specific stimuli. For...

This essay also examines the distinctions between classical and operant condition and examines “extinction” as it relates to psychological theory and how extinction is achieved in classical and operant conditioning. Phobias and Addictions Numerous psychologists believe that behaviors are learned through conditioning. These conditionings are known as operant, which is based on individual’s response to outside stimuli, and classical conditioning, which is based on the theory that people’s reactions to situations are learned behaviors. Phobias and Addictions can develop when an individual’s ability to function within societal normality’s or adapt to societal complexities are diminished. Addiction is a condition in which the body must have a drug to avoid physical and psychological withdrawal symptoms. Phobias and classical conditioning Phobias are persistent and irrational fears of specific objects, activities, or situations that are excessive and unreasonable, given the reality of the threat. Even though phobias are based on irrational fears, they often cause serious problems in a person’s life. Phobias can result in a person being unable to perform their job, participate in......
