Communication Theory Essay Example | Topics and Well Written Essays - 1000 words

Communication Theory - Essay Example The various functions of the communication theory will be discussed briefly which include the function of measuring the amount of information is transmitted, the amount of information being generated, the different types of sources, the interdependence of these sources and concepts such as noise, equivocation and causality of information. The chapter will provide a basic understanding of these concepts and will provide a clear understanding of the strengths and weaknesses of the theory in measuring communication taking place. The communication theory is a purely quantitative theory used to measure how much information is transmitted to be associated in a given state of affairs and which would then in turn provide a measure as to how much information will be available at various points. This theory discusses the amounts of information being transmitted, not the type of information, as the name provides a misleading direction. In respect to studying the amount of information generated this theory works in a sort of elimination technique removing all the possibilities which have been calculated to not exist. Eliminating all the choices which will not occur provides information as to the narrowing down of the decision. A binary decision, where the elimination of half the possibilities takes place till the required outcome is obtained, is also an elimination technique used to generate information related to selections (tossing of coins selecting the winner and eliminating the loser). Bits are the number of times a binary decision has to take place before getting to the required outcome. The general formula used to compute the amount of information generated is: I(s) = log n Here the I(s) is used to denote the amount of information generated by the association of the source. n is the number of equal possibilities that may or may not occur. This formula raises a point which must be distinguished that is that the amount of information (in bits) created by some state of affairs is different from the number of binary digits that will be used to represent the state of affairs. Both are different aspects. Using binary digits instead of distinguishable characteristics can cause in the creation of less efficient codes and would cause a more complex selection and elimination process. I(s) can also be referred to as the average amount of information generated by the source which is also called the entropy of the source at s. Similarly a source r can take place. This source causes an elimination of alternatives and can be interdependent with the source s. Thus I(s) and I(r) are also interdependent. But sometimes the possibilities of occurrences are not equable. These different possibilities s1, s2,,sn can be written in the form of p(si). This is often called the surprisal of the particular event. These formulas and probabilities prove that the communication theory deals with the sources rather than be concerned with the particular messages or the amount of information associated with the events occurrence. When calculating the average amount of information associated with a given source I(s) capable of providing different individual results then we take the surprisal values of all the specific individual possibilities of that source.

The Art of Cooking Rice - Assignment Example When measuring rice for cooking, one typically uses a cup for measurement. Decide on the number of cups to cook and then rinse the rice with ordinary water to rid it of starch and any other impurities. Common rice sold in the US is usually fortified with key vitamins and minerals (like iron and niacin), most of which will be washed away if the rice is soaked and washed prior to cooking (Smith and Dilday). However, soaking and washing rice will result in fluffier, lighter cooked rice, with fuller grain that doesn't stick. Either soak the rice in cold water for 30 to 60 minutes or wash the rice around two to three times or until the water is clear rather than cloudy. In washing rice, one technique would be to keep the water running on low while shaking the rice until the foggy white color turns to clean clear.

In washing rice, one technique would be to keep the water running on low while shaking the rice until the foggy white color turns to clean clear. Then, rinsed rice has to be placed in a standard pot. It is advisable to use a heavy pot rather than shallow pans or thinly lined pots because rice needs quite some time to cook and it has to cook evenly. If one uses a thin-lined pot, one would end up with burnt rice at the bottom and uncooked rice on top. Most people also just decide to use a rice cook er to make the job easier. Either way, make sure that the right amount of water is mixed in with the rice. The rule of thumb when cooking rice is usually two cups of water for every cup of long grain rice, one and a half cups of water for every cup of short grain rice, and one and one-fourth cups of water for every cup of sweet rice. These combinations yield three cups of cooked long grain rice, two and a half cups of short grain rice, and two cups of sweet rice, respectively (Compestine). Mixing in the right amount of water is essential to ensure that cooked rice is neither mushy nor gritty. Assuming that a rice cooker is not used, put the pot over a stove and bring the rice and water to a rolling boil over medium or high heat.

Aboriginal land rights in Australia Research Proposal

Aboriginal land rights in Australia - Research Proposal Example o Aborigines, Diane Bell has boldly expressed it as a sign that there is a drastic alteration in the legal and administrative stance to the acknowledgment of Aboriginal rights in Australia. Bell further justified her claims through pronouncing these statements;"Nowhere are these changes as striking as in the struggle of the Aboriginal people to gain recognition of land rights. This struggle has involved both moral and legal re-examinations of the relationship between a settler population and the original inhabitants. The wording of the Land Rights Act Northern Territory (1976) and the reference to customary law both assume that Aborigines have rights and a system of law, and that these have existed for many thousands of years. Such propositions would have been unthinkable two hundred years ago, when Australia was settled as a British colony. Not only has the legal profession had to rethink its judgments and governments to legislate to recognize aspects of Aboriginal Rights, but th e Aborigines themselves have organized locally and nationally to bring the grievances and the injustices suffered by their people to the attention of other Australians and to people abroad."1 Nevertheless, there are alarming difficulties regarding the debate on land rights. The issue has branched out extensively to include political implications which made it extremely complicated to represent objectively and impartially. In a scholarly matter, it is rather inappropriate to provide an in-depth analysis of the causes of the land rights battle while it is still being fought. Neutrality of opinion regarding a politically charged state of affairs can be then argued as an indication of support to the conservative racist forces in Australia which combat the bestowing of land rights to the original inhabitants of Australia. Nonetheless, there is an urgent need to expose and investigate the issues revolving around the land rights movement since arguments and raison d''tre on both sides of the problem are dreadfully ambiguous. A tranquil and balanced evaluation of the diverse issues of the land rights movement can possibly generate a remedial and enlightening effect and conceivably guide those who are fervently faithful to the land rights proposal to come up with a persuasive way in presenting their case. Many Australians advocate the recognition of the Aborigine's traditional land rights which constitute the right to utilize and subsist on the land that they have previously occupied. The supporters of the land rights movement give their best hopes that a greater recognition of these customary rights, which is termed as the native title, would smooth the progress of compromise between Aborigines and white Australians. However, the land claims of the Aborigines demonstrate composite legal concerns, such as the problems that granting of native titles will cause to private welfare in the land that have existed in Australia over the past two decades. The complex issue over land rights necessitates the vitality of confronting the problem with the deep-seated legal principles regarding land rights of aboriginal people. The Land Rights Movement In the 1960s, the Aboriginal land rights movement inaugurated its emergence as a "movement", as such. The term "movement" is quite an inappropriate word to use since the

Variation in Real Estate Prices and Macroeconomic Performance Assignment

Variation in Real Estate Prices and Macroeconomic Performance - Assignment Example The performance of the housing sector significantly affects the general economy’s performance. Most theories, however, presume that it is only the macroeconomic factors that affect the variations in house prices and not the reverse. According to the vector autoregressive (VAR) model built by Baffoe - Bonnie, there are complete relations between the housing sector and the general economy (Case et al. 15). The theory asserts that macroeconomic variables usually cause cycles in the prices of houses and the number of houses sold. If not brought to control, these effects may have adverse implications on the economy. Historically, changes in the prices of the real estate have been linked to changes in consumption in various ways. In the past, the slump in housing led to many empty houses and growing joblessness. Uncertainty about the consequences of declining home prices was also common in the past years. In the past - just like today, consumption or rather spending has been subject to people’s income. Economists Karl E. Case, John M. Quigley and Robert J. Shiller made annual observations in 14 countries since the past 25 years and in some U.S. states quarterly in the 1980s and 1990s. Their observation was that some the future incomes were kept in the assets, stocks, bonds, and property, where most people keep their riches (Case et al. 15). A drop in asset values made many homeowners poorer, so they lowered their expenditure and raised savings. When the assets grew, they spent more. The theoretical arguments of the vector autoregressive (VAR) model are thus valid. Economists have varying opinions on the consequences of varying house prices among the consumers. According to Carroll et al. (69), they disagree as to whether Americans will reduce their spending slowly or rapidly. On one side optimists, argue that the links between housing wealth and spending are much the same as for any other type of wealth, such as shares. They say

The secret society - illuminati Essay Example for Free

The secret society illuminati Essay This article is about the secret society. For the film, see Illuminata (film). For the Muslim esoteric school, see Illuminationism. For other uses, see Illuminati (disambiguation). Adam Weishaupt (1748–1830), founder of the Bavarian Illuminati. The Illuminati (plural of Latin illuminatus, enlightened) is a name given to several groups, both real and fictitious. Historically the name refers to the Bavarian Illuminati, an Enlightenment-era secret society founded on May 1, 1776 to oppose superstition, prejudice, religious influence over public life, abuses of state power, and to support womens education and gender equality. The Illuminati were outlawed along with other secret societies by the Bavarian government leadership with the encouragement of the Roman Catholic Church, and permanently disbanded in 1785.[1] In the several years following, the group was vilified by conservative and religious critics who claimed they had regrouped and were responsible for the French Revolution. In subsequent use, Illuminati refers to various organizations claiming or purported to have unsubstantiated links to the original Bavarian Illuminati or similar secret societies, and often alleged to conspire to control world affairs by masterminding events and planting agents in government and corporations to establish a New World Order and gain further political power and influence. Central to some of the most widely known and elaborate conspiracy theories, the Illuminati have been depicted as lurking in the shadows and pulling the strings and levers of power in dozens of novels, movies, television shows, comics, video games, and music videos. The movement was founded on May 1, 1776, in Ingolstadt (Upper Bavaria) as the Order of the Illuminati, with an initial membership of five,[2] by Jesuit-taught Adam Weishaupt (d. 1830),[3] who was the first lay professor of canon law at the University of Ingolstadt.[1] It was made up of freethinkers as an offshoot of the Enlightenment and seems to have been modeled on the Freemasons.[4] The Illuminatis members took a vow of secrecy and pledged obedience to their superiors. Members were divided into three main classes, each with several degrees, and many Illuminati chapters drew membership from existing Masonic lodges. The goals of the organization included trying to eliminate superstition, prejudice, and the Roman Catholic Churchs domination over government, philosophy, and science; trying to reduce oppressive state abuses of power, and trying to support the education and treatment of women as intellectual equals.[1] Originally Weishaupt had planned the order to be named the Perfectibilists.[2] The group has also been called the Bavarian Illuminati and its ideology has been called Illuminism. Many influential intellectuals and progressive politicians counted themselves as members, including Ferdinand of Brunswick and the diplomat Xavier von Zwack, the second-in-command of the order.[5] The order had branches in most European countries: it reportedly had around 2,000 members over the span of ten years.[1] It attracted literary men such as Johann Wolfgang von Goethe and Johann Gottfried Herder and the reigning dukes of Gotha and Weimar. In 1777, Karl Theodor became ruler of Bavaria. He was a proponent of Enlightened Despotism and his government banned all secret societies including the Illuminati. Internal rupture and panic over succession preceded its downfall.[1] A March 2, 1785 government edict seems to have been deathblow to the Illuminati in Bavaria. Weishaupt had fled and documents and internal correspondences, seized in 1786 and 1787, were subsequently published by the government in 1787.[6] Von Zwacks home was searched to disclose much of the groups literature.[5] Barruel and Robison Between 1797 and 1798 Augustin Barruels Memoirs Illustrating the History of Jacobinism and John Robisons Proofs of a Conspiracy both publicized the theory that the Illuminati had survived and represented an ongoing international conspiracy, including the claim that it was behind the French Revolution. Both books proved to be very popular, spurring reprints and paraphrases by others[7] (a prime example is Proofs of the Real Existence, and Dangerous Tendency, Of Illuminism by Reverend Seth Payson, published in 1802).[8] Some response was critical, such as Jean-Joseph Mouniers On the Influence Attributed to Philosophers, Free-Masons, and to the Illuminati on the Revolution of France.[citation needed] Robison and Barruels works made their way to the United States. Across New England, Reverend Jedidiah Morse and others sermonized against the Illuminati, their sermons were printed, and the matter followed in newspapers. The concern died down in the first decade of the 1800s, though had some revival during the Anti-Masonic movement of the 1820s and 30s.[2] Modern Illuminati Several recent and present-day fraternal organizations claim to be descended from the original Bavarian Illuminati and openly use the name Illuminati. Some such groups use a variation on The Illuminati Order in the name of their organization,[9][10] while others such as the Ordo Templi Orientis use Illuminati as a level within their organizations hierarchy. However, there is no evidence that these present-day groups have amassed significant political power or influence, and they promote unsubstantiated links to the Bavarian Illuminati as a means of attracting membership instead of trying to remain secret.[1]

Role of Regulation of Breathing

Role of Regulation of Breathing UAC 1.2: Detail the role of the regulation of breathing. Question 1: During exercise, the rate of breathing increases. How does the body detect, coordinate and respond to increase pulmonary ventilation and why is it important? (250 words max) When exercising the pulmonary ventilation rate and depth expands so oxygen can diffuse from the air to the blood quicker and carbon dioxide can diffuse from the blood to the air faster. The brain is ultimately in charge of breathing; the brain stem utilises sensors to manage breathing. Breathing results from coordination of three interactions; a sensory system, respiratory control centre and an effector system. These sensors, called chemoreceptors are supported by nerves and muscles. Chemoreceptors recognise chemical substances and pass this data to the nerves in the central nervous system. During exercise there is an expansion in carbon dioxide which causes a reduction in the pH of blood. The additional carbon dioxide in the blood is detected by the chemoreceptors. Because of a diminishing in the pH, the respiratory control centre in the medulla, sends nervous impulses which instruct the intercostal muscles and diaphragm to contract harder and all the more often, which increase the breathing rate and the volume of the lungs during inhalation. Working together, the body is continually monitoring and adjusting pH and oxygen in the arterial blood. Breathing endeavours to maintain stability. Elevated amounts of carbon dioxide triggers speedier and more profound breathing. This expanded breathing reduces the concentration of carbon dioxide in the blood increasing the measure of oxygen taken in. UAC 2.1: Explain the process of ventilation including detail of lung volumes and capacities. Question 2: Explain, using Figure 1, how a human body inhales and exhales air. Include explanations of vital capacity, residual volume, tidal volume, ventilation rate and pulmonary ventilation. (350 words max) Figure 1: Spirometer trace Pulmonary ventilation is the movement of air into and out of the lungs. It is activated by the changes to the volume and air pressure in the lungs. There are two phases of ventilation: Inhalation is the admission of air into the lungs through the expansion of the chest volume and exhalation is the removal of air from the lungs through contraction of the chest volume. During inhalation the diaphragm contracts, simultaneously the intercostal muscles allow the rib confine to raise. This creates a drop in the pressure inside the lungs and extends the chest cavity, subsequently expanding the lung volume making a partial vacuum causing air to be passively drawn into the lungs from the respiratory tract to fill that space. The reverse occurs during exhalation. The muscles no longer contract and are relaxed. The diaphragm curves and raises, the intercostal muscles descend and the chest volume decreases. The chest cavity contracts therefore increased air pressure, causing the air in the lungs to be expelled passively through the upper respiratory tract. This is known as the tidal volume which is the volume of air took in and out in one breath when at rest. Sufficiency of ventilation is measured by a spirometer, (an instrument for recording volumes of air taken in and breathed out). Figure 1 demonstrates a following of a spirogram. Each breath invigorates a quantity of the air in the lungs and carries away a quantity of the carbon dioxide made by the body. Air moves in and out of the lungs around 12 times per minute in the average person as the diaphragm and intercostal muscles contract and relax, this is the ventilation rate and is calculated by the number of peaks in one minute. At the point when a person breathes in and out profoundly then considerably more air can be exchanged, this is known as vital capacity. The oxygen take-up is different as the carbon dioxide is expelled, the tidal volume in the air chamber decreases. The volume of air removed is shown by the distinction in height of the last peak from the first peak amid ordinary breathing. There is constantly some air left in the lungs that cannot be exchanged in light of the fact that the alveoli do not completely collapse; this is known as the residual volume. UAC 2.2: Explain the characteristics of efficient gaseous exchange and show with reference to diagrams how this is achieved in the lungs and capillaries. Question 3: Explain, using Figure 2, how the structures of the lungs and capillaries are adapted for efficient gas exchange. (450 words max) Figure 2: Diagram of an alveolus The lungs are adapted for the effective gas exchange; the exchange surface must have the ability to exchange gases quickly enough to oblige the requirements of the cells. The lungs contain a huge number of tiny, air-filled sacs called alveoli. Within the alveoli, an exchange of gases happens between the gases inside the alveoli and the blood by passive diffusion. The alveoli are adapted to make gas exchange in the lungs happen effectively and proficiently. The walls of the alveoli are a single cell thick and are made of flattened epithelial cells, making the exchange surface thin which shortens the diffusion pathway over which gases need to make. In order to maximise the amount of diffusion taking place, the alveoli are folded up truly fine, giving an expansive surface area. This means more gas can be exchanged at the same time and it happens speedier which implies the lungs can ventilate faster. The alveoli have a moist layer; this moisture is passed through the cell membrane of the alveolar cells. The alveoli are kept moist to dissolve gases. The moist lining additionally diminishes the surface strain, which means less energy is required to inflate the alveoli and prevents the collapse of alveoli. Every alveolus is encompassed by numerous capillaries; these capillaries are slender so that the red blood cells are squeezed against the capilla ry wall giving a good blood supply, therefore giving a short diffusion pathway. For the exchange of gases to be fast, a steep diffusion gradient is required. The concentration gradient is the distinction in concentration between two focuses. This is to guarantee the molecules diffuse quickly and in the correct bearing. In the lungs the presence of a very thin permeable diffusion pathway of just two flattened cells helps to create a steep concentration gradient. Every alveolus is ventilated, evacuating waste carbon dioxide and replenishing oxygen levels in the alveolar air. The blood arriving in the alveoli has a higher carbon dioxide concentration which is delivered amid breath by the bodys cells. However, the air in the alveoli has a much lower concentration of carbon dioxide, which means there is a concentration gradient which permits carbon dioxide to diffuse out of the blood and into the alveolar air. Similarly, blood arriving in the alveoli has a lower oxygen concentration, as it has been utilised for respiration by the cells of the body, while the air in the alveoli has a higher concentration. Consequently, oxygen moves into the blood by diffusion and integrates with the haemoglobin in red blood cells. This continual supply of gas to one side of the exchange source and its expulsion from the alternative side ensures that diffusion, and therefore exchange, can proceed.  ­Ã‚ ­ References Grant, A.
