Abstract
This paper reviews the article "Viewing a Map versus Reading as Description of a Map: Modality-Specific Encoding of Spatial Information" written by Tlauka, Keage and Clark. According to the paper, the article reports results of a study that was conducted in order to determine if neural activity within the human brain, that had accompanied processing of previously-learned information, about positions and locations of various places on a map, was measurably influenced by the particular modality in which spatial parameters of the maps themselves had been learned originally.
From the Paper
"In the learning phase, the study participants either looked at a map, or read a written description of a map. Next, study participants' comparative abilities to use the spatial knowledge they had learned earlier, either visuospatially [sic] or verbally, was measured, by having each of the participants then perform a spatial orientation task, during which EEG activity was measured. According to the authors, brain activity relative to processing spatial information was inferred from amplitude, latency, and topography of several spatiotemporal parts of the ERP. The authors found that overall performance was unaffected by previous map-learning modality (visuospatial [sic] or verbal), but that the neural activity underlying processing of stimuli was in fact influenced by previous map-learning modality (e.g., visuospatial [sic] or verbal). Based on this result, the authors concluded that conflicting results derived from the behavioral and Neurophysiological measures suggest that adopting particular orientations in imagined space can involve different patterns of brain activation."

From the Paper
"According to chalk (2005) Agroterrorism is defined as "the deliberate introduction of a disease agent, either against livestock or into the food chain, for purposes of undermining socioeconomic stability and/or generating fear. Depending on the disease agent and pathogenic vector chosen, Agroterrorism is a tactic that can be used either to cause mass socioeconomic disruption or as a form of direct human aggression (Chalk 2004, vi)." Kohnen (2000) asserts that threat of an agroterrorist event could be contingent upon the following three factors: (1) a terrorist or terrorist group must posses the technical ability to get hold of and deploy the weapon (Kohnen 2000). (2) the terrorist or terrorist group must be attracted to sickening or killing animals or crops as a part of its goal (Kohnen 2000). (3) the terrorist or terrorist group must have the desire to carry out their goal through the use of a Biological Weapon (Kohnen 2000)."

Abstract
This paper presents the debate of the advantages and disadvantages of stem cell research. It then suggests, though an overview of the debate, that while stem cell technology and research offers the potential for medical advancements, at the same time it poses many ethical and practical problems which could have a potentially negative effect on modern society and culture.
Table of Contents:
Introduction
Stem Cell Research Overview
The Negative Side Of Stem Cell Research.
Summary And Conclusion
From the Paper
"The views expressed above epitomize the central concerns that surround the future implications of stem cell research for society. Many thinkers realize that the underlying danger inherent in cloning is that the act of reproduction and human creation will become a 'production of a product', which will exclude human nature and active creation and deprive culture of a necessary sense of awe and mystery at life. This fear is described by Rifkin and in clear and alarming way. He sees a situation developing where the eventual results of stem cell research will result in a situation where the "gift of life" "...is steadily marginalized and eventually abandoned all together. In its place the new progeny becomes the ultimate shopping experience--designed in advance, produced to specification, and purchased in the biological marketplace. " (Rifkin)"

Abstract
This study aims to identify the specific constituents of the vitamin B complexes in general and then goes on to describe how deficiencies of these vitamins adversely affect human health. The paper discusses which aspects of the population are at higher risk of vitamin B deficiencies and what can be done to remedy the problem. The paper specifically talks about the relationship between mental health issues and vitamin B deficiencies.
Table of Contents:
Chapter 1: Introduction
Statement of the Problem
Purpose of Study
Importance of Study
Chapter 2: Review of Related Literature
Chapter 3: Conclusion
From the Paper
"Given the above, it is clear that people can experience essential nutrient deficiencies even when they are consuming the recommended daily allowances. While it remains vitally important to prevent such vitamin deficiency syndromes, there is a paucity of scientific evidence that additional intake levels that exceed the recommendations set out in Table 3 above of protein or micronutrients in supplement form is able to enhance athletic performance, notwithstanding the claims of manufacturers to the contrary (Chee et al., 2001). These authors caution that these supplements can actually interfere with the metabolism of the vitamin B complexes, thereby making matters worse instead of better. "In fact, isolated amino acid supplements may impair the uptake and utilization of other essential amino acids from diet, and vitamins and minerals (particularly fat soluble vitamins) may be toxic in high doses. The most common deficiency states in elderly persons related to exercise and functional capacity are energy, protein, potassium, magnesium, vitamin B12, and vitamin D" (Chee et al., 2001, p. 194)."

The Arabian Horse Breed, 2007.
A discussion on whether the Arabian horse breed is superior to other horse breeds.
1,678 words (approx. 6.7 pages), 8 sources, MLA, $ 54.95
»
Click here to show/hide summary
Abstract
The paper examines whether the fact that Arabian horses have fewer bones means that they are superior horses. The writer proposes that their superiority is subjective. The paper explains how the Arabian has fewer bones, with many horse experts and breeders preferring the Arabian. The paper analyzes whether the fewer-boned horse has advantages over the other horses in the field.
From the Paper
"One of the things that allows the Arabian to be very good at endurance riding is the fact that the hind legs are "remarkably free" in their ability to move and be limber, Edwards explains in the book. The tail of the Arabian is set very high in the croup, and while moving, the tail of the Arabian "is carried arched and well up," a point horse experts notice when discussing the style which the horse shows while running."

Environmental Stresses, 2007.
An overview of environmental stresses in mangrove swamps and coral reefs.

Abstract
This paper compares and contrasts some of the environmental stresses faced by two marine ecosystems: the coral reefs and the mangrove swamps. It attempts to show that despite differences in types of ecosystem stressors, both share common anthropogenic stresses. The paper begins by describing the coral reefs and mangrove swamps and then describes the threats to them, environmentally.
From the Paper
"Despite the vast amount of coral, that can seem mind-boggling at times, the specific environmental conditions required by coral means that it can be very susceptible to environmental changes. For examples, relatively minor surface water temperature increases can kill, or bleach, coral reefs. In Hawaii Jokiel and Brown (2004) found that sea surface temperature increases of just more than 1 degree C caused significant coral bleaching in both 1996 and 2002. They observed that the overall trend of oceanic warming is causative for increases in the frequency and severity of coral bleaching worldwide. While global warming has been pointed to as the reason for this increase, there are more direct ways that man is placing new environmental stresses on coral reefs. "

Exploding the Myth of Race, 2007.
This paper examines the ideas presented in "The Emperor's New Clothes" by Joseph L. Graves.
1,500 words (approx. 6.0 pages), 1 source, MLA, $ 49.95
»
Click here to show/hide summary
Abstract
The paper discusses the biological anthropologist Joseph L. Graves' suggestion that race is a culturally and socially constructed idea, not a biological fact. The paper identifies how he takes contention with many of the assumptions of the modern scientific community in the fields of medicine and anthropology; he maintains that blood groups or genetic diseases are not exclusive to confined racial groups. Graves makes a persuasive case that human beings must look beyond artificially constructed racial barriers - both laypersons and traditional medical researchers. The paper concludes that culture is a more powerful influence upon individual human health than the genetic and biological legacy that we all, as members of homo sapiens, commonly share.
From the Paper
"Sickle cell anemia, a disease associated with African Americans, is actually a genetic mutation that protects against malaria found primarily in individuals of West African ancestry. The supposed 'Black' race does not manifest the genetic trait of sickle cell across the entire African continent sparing the geographical expanse from Ethiopia to Cape Town. To further confuse racial categories of Blackness, sickle cell anemia is present in European Mediterranean ethnic groups, in a slightly different form, even though these persons might not share such conventional physical markers of race in terms of their physical appearance."

The Dangers of Anthrax, 2007.
Questions whether anthrax is a dangerous weapon.
1,682 words (approx. 6.7 pages), 5 sources, APA, $ 54.95
»
Click here to show/hide summary
Abstract
In the wake of the September 11, 2001 terrorist attacks on the United States, anthrax, a deadly chemical agent, began showing up in many areas of the East Coast. The nation came to fear anthrax, but was that fear justified? The paper argues that while the anthrax outbreaks caused relatively few deaths, the use of anthrax as a weapon of bioterrorism should be anticipated with fear and dread. The agent is deadly and the vaccines against it are controversial at best. The paper shows that anthrax is indeed a weapon of mass destruction if it falls into the wrong hands.
From the Paper
"Perhaps the most disturbing aspect of anthrax is its longevity. The spores can lie dormant for literally years, but they can still infect a person after years of exposure to the elements. Researchers know this because of past studies conducted on the disease and the spores that cause it. For example, British researchers studied the disease and its affect on animals for about a year in an isolated Scottish bog during World War II. During their studies, they exposed sheep to various types of weapons containing anthrax spores, including bombs, bullets, and other dispersants."

Abstract
This paper looks at gene expression profiling which is defined as a basic research method that effectively measures messenger RNA that has been made up of many different genes belonging to many different cell types. It discusses how this technology is being widely accepted and used as a diagnostic test to help the technician to easily identify the various subgroups of tumor types and to help predict which patients would better respond to treatment, and also which patients may be at an increased risk of a relapse of cancer.
From the Paper
"Any cells, within an organism, like for example, within a human being, works especially in order to increase the basic functioning and efficiency of that organism. For example, Nerve cells, or in other words, neurons, are capable of expressing neuron specific proteins, and this would allow it to perform neuron duties more efficiently. Similarly, skin or epithelial cells have their very own and specific proteins, and this enables them to work better. It must be noted that both neurons as well as epithelial cells possess the genes-encoding for neural and epithelial-specific proteins, and this makes sure of their effective and efficient and protective functioning. However, each cell can only express that particular gene that it may require, and not any other tissue specific genes. What this may be taken to mean is that a given DNA sequence can only provide specific information about what 'could be', and not what actually 'is'."

Abstract
The paper describes how the film "Gattaca" is a look into a possible future based on the concerns people have today about DNA testing, genetic engineering, privacy and similar issues. The paper discusses how the film raises a number of questions about what these trends might lead to in the near future and the film plays directly on fears that have been expressed by many people today. The world depicted in the film is centered on a huge corporation that monitors its employees closely and that makes decisions on the basis of genetics. The paper highlights the danger that a few scientific facts can become an excuse for unlimited social control.
From the Paper
"The main character is Vincent, who has found a way around the system and is passing as a man named Jerome. Every morning, he goes through a ritual to install the hair, skin cells, and urine of a crippled man named Jerome, a man who would have had a bright future if he had not been crippled in an accident. Jerome dreams of going into space, which is the business of Gattaca, and he is about to fulfill that dream unless he is uncovered and his true genetic make-up discovered. This might happen because the director of the project has been murdered, and the police investigation could discover the truth about Vincent's DNA."

Abstract
This paper examines the assumption that the gene revolution--represented by the integration of genetic engineering techniques into the field of agriculture--is capable of positively affecting the current human population crisis. The study examines this very ideological assumption that has not largely been challenged in the popular or critical literature on the subject. It then attacks that assumption and illustrates its erroneous base.

From the Paper
"In order to fully examine that relationship, it was necessary to critically examine literature, statistics, and historical examples that might shed some light on the relationship that exist between food production and population growth. Additionally, studies were consulted that spoke to the capacity for genetically modified foods to increase agricultural production. In all, the range of information required for this study was significant and at times may have appeared to stray beyond the limited scope of genetically modified food. However, in order to demonstrate the manner by which genetically modified food would have its greatest negative impact upon human societies, it was essential to take a broader look at the role that genetically modified foods have played in the intense push to intensify agricultural production year after year in order to presumably keep up with geometric population growth by always generating more food than is needed."

Toxicology, 2006.
This paper discusses the science of toxicology or the science of poisoning.
1,102 words (approx. 4.4 pages), 9 sources, MLA, $ 38.95

Abstract
The writer begins this essay with a discussion of the metabolism of toxic substances. The writer explains that the rate of metabolism in effect defines the concentration of the toxic substance. The slower the metabolic rate the more easily the toxic substance enters systemic circulation. Further, in this paper the writer discusses possible poisoning from chemicals such as aspartame or aspirin. The writer concludes this study with a look at the Bhopal carbide plant disaster in 1984.
From the Paper
"The human liver plays an important role in metabolizing and breaking down food material, (including toxic substances) before it can reach the circulatory system and affect the entire body. Nature has defined the liver as a first line defense mechanism against food materials and toxic substances that we may consume unknowingly. The metabolizing enzymes in the hepatocytes are very efficient and this defense mechanism is known as 'first pass effect'. Typically, Phase one reactions are mainly oxidative, reductive or hydrolytic processes and form substrates for phase two conjugations. The cytochrome p450 enzymes are mainly responsible for the Oxidative phase one reactions. These are a group of enzymes that are actually a family of proteins that can act upon a wide range of substrates. Lipophilic chemicals are oxidated to yield water-soluble chemicals. These enzymes also perform heterocyclic hydroxylations and analkylation reactions. The end products of the phase one reactions are ready for conjugation with glycine, glucuronic acid, etc and are easily excreted from the body via urine."
