History of Eastern United States Coast Barrier Islands Research Paper

History of Eastern United States Coast Barrier Islands - Research Paper Example The Native Americans first occupied these barrier islands. They were later taken over by the European settlers for their recreational and touristic pursuits. However, they have diminished in size and retreated in the past years due to rising sea level, diminishing sediment, storms, and human interference. Extensive human settlement in these areas has raised concerns regarding the loss of habitat. Although vulnerable, these barrier islands are very important economically, serving as areas for tourist development, the source of food, and employment.

They usually create chains situated a number of miles offshore alongside the many passive margins. The back barrier region separates the barrier island from the mainland and shallow bays, marshes, estuaries, or lagoons usually occupy it. Barriers are created by the vertical accumulation of the sand from wind and waves action. Barrier islands are called so because they signify the shoreline natural protection from the forces of tsunamis, tides, currents, and waves from the core ocean. However, the majority of the barrier islands have been turned into resort-type living and beautiful beaches (Kusky 2008, 5). The development of the barrier islands characterizes one of the most dangerous trends in the coastal zones. This is because barriers are jutt ed mobile strips of sand moving in response to the changing storms, tides, coastal currents, and sea levels. Storms are able to move the complete sandy substrate out from the underneath of the tall buildings. Kusky (2008, 6) states that â€Å"the size of barrier islands ranges from narrow and discontinuous strips of sand that may be only a few hundred feet wide, too large islands that extend many miles across and also in length.† The length and the width are calculated from the existing amount of sediment and the balance between the tidal and wave energy. Majority of the barriers are built from sand (sand from the eroded coastal cliffs, deposited by rivers along the delta systems or sand left from the glaciations). Barrier islands are supposed to be discontinuous to permit water from the tidal changes to get back to the sea along the tidal inlets systems (Kusky 2008, 6). The sub-environments of barrier islands are classified the same as those of beaches. These sub-environment s include barrier interior, landward interior, and the beach. The beach face of the barrier is the most vibrant section of the island. It absorbs energy from the tides and waves and responds much like the mainland beaches. The beach backside of many barrier islands are marked by a foredune ridge or along frontal, followed landward by the secondary dunes.

Sociology class - Essay Example So what does sociology actually imply? For me, based on my own understanding, sociology is concerned with individual action that is unavoidably connected to the action and behavior of other people. Hence, the focus of sociology is quite extensive, encompassing all issues of our social behavior. Nevertheless, the abovementioned description of sociology can be confined. Take for instance an aspect of behavior like a consumer’s decision to buy a product. In general we would view this behavior as an economic act in the sense that it involves a monetary transaction. However the consumer’s choice to buy can also be regarded as being a sociological act, because it definitely has personal significance for the consumer, and it is directed towards the assumed and actual conduct of other actors such as salespeople, other consumers, etc. So what is the importance of sociology? Why do we have to learn about it? Sociology becomes increasingly important nowadays due to the sweeping progress of globalization. This event led to the far-reaching transformation of the globe’s political landscape. The traditional state was displaced by a completely new form of ‘nation state’ founded on transnational institutions, areas, and metropolises. Hence, because of this, sociology becomes indispensable to the understanding of the effects of globalization on the current standing of the nation state. However, some argues that sociology loses its importance because of globalization. I do not think so. Sociology will never lose its importance in present-day civilizations. While long-established societies and cultures were displaced by the new systems, a contemporary sociology embracing them displaced traditional sociology. Certainly, the similarity between traditional sociology and the contemporary one is that as the former emerged in reaction to contained modernization, observed through the occurrences of industrialization and, later on, urbanization, contemporary

Low Testosterone Levels in Relation to Depression Research Paper

Low Testosterone Levels in Relation to Depression - Research Paper Example This is because; serotonin is a neurotransmitter that relays messages from one region of the brain to the other (Gonzales, et al., 2002). Therefore, the levels of testosterone hormones in an individual, determine their levels of serotonin. It is observed that the older male individuals who have low levels of testosterone have also low levels of serotonin. Thus, with low levels of serotonin, the rate of transmission and relaying messages in the brain is lowered, making an individual less active (Berglund et al., 2011). The less activity of an individual increases their levels of anxiety and consequent low moods, which are symptoms associated with depression. Serotonin is known to influence a higher percentage of brain cells, mostly those related with moods, sexual desire, social behavior, memory and learning, as well as sleep (Devina, et al., 2010). When the serotonin levels in the body are low, the levels of activity in these brain cells are also low; an aspect that promotes low mood s, low memory and low social behaviors and interaction, which on the other hand promote depression. Therefore, whenever the brain cells are suppressed due to low activity or inactivity caused by the low serotonin levels, depression may arise, always preceded by stress as the preceptor of the brain cells (Carnahan & Perry, 2004). Therefore, it is observed that the relationship between testosterone levels and serotonin, have an influence on men’s depression. Depression is likely to be higher in women than men, until the age of 65, when the gender difference disappear, and the men become equally depressed as their female counterparts (Berglund et al., 2011). This is because, testosterone levels decreases with age in males, although the rate at which the decline... This research paper focuses on a positive relationship between testosterone levels and depression in men. Such effective relationship that is a main focus of the essay, takes the form of low testosterone levels triggering depression causative agents, such as anxiety, low social activity, anorexia and insomnia. As male individuals grow older, their testosterone levels decrease. The researcher provides a reference, that for men aged between 20-40 years, only 1% has a diagnosys for low testosterone levels. Therefore, men who are above the age of 55 years are observed to have a low level of testosterone hormones. Low testosterone levels are also observed to affect the Serotonin levels in the body and notably the brain, which in turn impacts on an individual body activity, moods and stress, causing depression. This has a large bearing not only on their psychological and emotional state but also may turn affects on their levels of depression. This essay also discusses the terminology and d escription of adult's depression itself. It is described that depression is likely to be higher in women than men, until the age of 65, when the gender difference disappear, and the men become equally depressed as their female counterparts. Therefore, testosterone treatment and replacement for men who does not respond to conventional depression therapy is highly recommended all over the world nowadays, though with a clear scrutiny into the likelihood of the testosterone replacement in causing cancer.

Transcendental Philosophy :: Paideia Philosophy Kant Papers

Transcendental Philosophy One needs specific initiation into the classics of transcendental philosophy (Kant’s "Criticism," Descartes’s "Metaphysics," and Fichte’s "Doctrine of Science") because all say farewell to the common sense view of things. The three types of transcendental thinking converge in conceiving rational autonomy as the ultimate ground for justification. Correspondingly, the philosophical pedagogy of all three thinkers is focused on how to seize and make that very autonomy (or active self-determination) intellectually and existentially available. In the concrete way of proceeding, however, the three models diverge. Descartes expects one to become master of oneself and "the world" by methodologically suspending his judgement on what cannot qualify itself to be undoubtable. Kant leads us to the point where we can triangulate universal conditions of the possibility of knowledge through individually acquiring the competence to judge the legitimacy of encountered propositional claims. Finally, Fichte confronts us with the idea of the identity of self-consciousness and objectivity. (1) Transcending ordinary life and experience to a somewhat higher being is surely not the scope of transcendental philosophy. What the revolutionary achievements of Descartes, Kant, and Fichte have generically in common is to account for the legitimacy of our knowledge claims or, in other words, for the possibility of autonomy. The business of that kind of philosophy is to rationally reconstruct the rightness of judging. For that design the architecture of those authors' theorizing is necessarily opposed to normal experience. (First of all, the common notion of "things affecting us" has to be abandoned.) Transcendental arguments are therefore all but common sense. They are in no respect "realistic" or ontologically dependent. (2) Whoever wants to get familiar with transcendentalism — perhaps just in order to criticize one or several of its representatives — must overcome the threshold of open or covert realism and ordinary experience. One also has to avoid the common misun derstanding that transcendental reconstruction represents a form of idealism. So this kind of philosophy seems to be a fortiori charged to give a good deal of pedagogical help for its own sake. The respective philosophical educations (paideiai) have to fight against the realist as well as the idealist tendencies of interpretation. Positively it is not enough for them to represent what is essential to transcendentalism as a genus; they must particularly transmit what is specific to Kant's "Criticism", to Descartes' "Metaphysics" or to Fichte's "Doctrine of Science". I. Rene Descartes was the first one to fully realize that reliable orientation could never passively be found in "things" or "institutions".

Speech On The Media s Speech For A Rethinking By Media...

This cover letter addresses the first essay for English 114, Democracy in the Media in which I critique and analyze the essay â€Å"Farewell to Journalism?: Time for a rethinking† by media critic Robert McChesney. I will look specifically at McChesney’s claim that American journalism is in peril danger and that massive government subsidies are the only way to save it, and our democracy. As I analyze McChesney’s claim, I will find major discrepancies within it and will make my own claim that although McChesney does his best to urge action from the reader he falls short on a number of issues that are vital to the success of his message. Throughout my paper I will present an idea or research that McChesney conveys to the reader, and I will explain my thinking and analysis of why it is incorrect and flawed. As I reflect on the process of creating my paper, I can think of multiple instances in which I understood the material excellently and analyzed the essay intensel y. I think that my practical and clear thinking is a strong point of my paper as I clearly outline what I feel McChesney has done incorrect within his argument. You will also see that I address his claim and how the evidence relates back to the claim many times in my paper as I slowly dissect and further understand his reasoning. However, as confident as I am in my hard-work I know that I struggled with many things throughout this essay as I began my learning experience at the college level. For instance, I clearly

Different Types of Energy and Its Many Uses - 969 Words

In the world today there are five different forms of energy available to us to use: mechanical, chemical, radiant, electrical and nuclear. (Tillery, 2009 p. 62) Each of these forms of energy can be converted from one type of energy to another. An example of this would be electrical energy turning into mechanical energy every time you use your blender. The electrical energy flows through the mechanical device providing it the power it needs to make the blade move in a circular motion and blend the items in the container. Another example of converting energy is when we use chemical energy in the form of propane, which turns into radiant energy when ignited, to cook food or provide heat when using a gas grill. Currently, one of the†¦show more content†¦Geothermal energy can be broken up into 4 different categories; dry steam, hot water, hot, dry rock and geopressurized resources. (Tillery, 2009 p. 70) Geothermal energy is found towards the earths inner surfaces where th e temperatures are higher than what we feel on earth’s surface. When water or lava come up from the earth’s inner core either from a volcano or from a geyser, the temperature of the liquid it produces would probably produce the same result we get from burning the fossil fuel we do today to run our power plants and with less pollution as we wouldn’t need to burn the source to produce the heat needed to run them. Overall, in my opinion, solar and geothermal energy would be a good replacement for fossil fuels. They are both a resource that could be replenished and it wouldn’t take a million years for it to happen. Also, as they are not chemical sources that need to burn, they would be less likely to add to the pollution we currently deal with because of the fossil fuels. The only disadvantages, or issues that need to be addressed, is our ability to mine and store the alternative resources in an equivocal monetary way as we currently do with fossil fuels .
