American International Group - Case Study Example The major business line of American International Group are functions, supports, services, and operations. The failure of these lines would result on the huge material loss of profit, revenue and franchise value for the organization as a whole. Therefore, American International Group prepared a resolution plan and for that purpose 22 companies as material entities were identified, from which one is AIG Markets, Inc; and the type of this entity is derivatives intermediaries. Fear of revenue, profit and franchise value loss motivated organization to be a part of derivatives market. American international group utilizes derivatives as a part of the company’s risk management framework. The major purpose of the company in entering in a derivative market is to mitigate the risk either by providing a profile of the investment or by hedging exposure. American international group is no longer engage in activities of derivatives that contributed materially to concerns throughout the fin ancial crisis or also not act as a market for the contracts of derivatives. The exposure of derivatives and derivative portfolio is examined on a regular basis in order to avoid any risk and fulfill the market standards of investment. Interest rate derivatives are used to deal with interest rate risk that is associated with insurance assets and liabilities. The company is involved in making investments in hybrid securities in order to generate more income. Therefore, company is involved in such derivative activities that are associated with investment operations for risk mitigation (AIG, 2014). After the financial crisis of 2008 the insurance industry like other industries faced backslash, this crisis and other infamous events proven as threat for the economy of the country. Many of American people rely on financial services for ability to get more mortgages, for investment opportunities and retirement savings. When ethical analysis taken into consideration, and the

Properties of Enzyme Catalysts

Properties of Enzyme Catalysts Introduction Enzymes:Enzymes are single or multiple -chain proteins that act as a biological catalysts with the ability to promote specific chemical rxn under the mild condition that prevail in most living organism. Over-view of Enzymes catalysts All reaction in the body are mediated by enzymes, which are protein catalysis that increase the rate of reaction without being changed in overall process. Among the many biologic reaction that are energetic possible, Enzyme selectively channel reactant called substrate into useful pathways. Enzynes thus direct all metabolic events. Enzyme are Protein Catalyst that increase the velocity of the chemical rxn, and are not consumed during the rxn they catalyse. Some type of RNA act like a Enzyme, RNA with catalytic activity are called Ribozymes. Enzymes are protein catalysts, they influence the kinetics but not the thermodynamics of a reaction Increase the rate of a chemical reaction Do not alter the equilibrium Properties of enzymes Enzyme molecules contain a special pocket called a active site. The active site contain amino acid side chain that create a three dimention surface complementary to the substrate . the active site bind the substrate , forming an enzyme substrate (ES) complex. The ES is converted to enzyme product(EP), which subsequently dissociated to enzyme and product. Catalytic efficiency: Most enzyme catalytic rxn are highly efficient , proceeding from 103 to 108 times faster than the uncatalysed rxn. Eacg enzyme molecule is capable of transforming 100 to 1000 substrate molecules into product each sec. The number of molecules of substrate converted to product is called the turnover no. Characterstic of Enzymes Certain substance is small amount have unique capacity of speedingup chemical rxn without being alter after the rxn, they acceleration the velocity of the rxn without necessary initially it. Substance that behave in this manner are called catalyst or catalytic agent. For eg hydrogen and oxygen do not combine to any appreciable extent under normal atmospheric condition. However unlike platinum , while is inorganic , enzyme are organic compound produce by living organism. Thus we may define enzyme as organic catalyst produced by a organic cell. The three distinctive characterstic are 1)specificity. 2)high Catalyst rate 3)high capacity for regulation. A general model of reaction kinetics of biological systems Dyanamic mathematical model in biotechnology require beside the information require the stoiciometry ok the biological rxn system.. The identification of a priori unknown reaction kinetics is often a critical task due to the non-linearity and (over-) parameterization of the model equations introduced to account for all the possible modulation phenomena. The contribution of this paper is to propose a general formulation of reaction kinetics, as an extension of the Michaelis-Menten kinetics, which allows limitation/activation and inhibition effects to be described with a reduced number of parameters. The dianamic model of a perfectly stirred tank bioreactor is usually derived from a mass balance which lead to a differential eq systwm for the concentration vector ) = c0; r(c(t))=q(c(t))cx0(t) The matrix âÅ'ˆâ‚ ¬R^m*n contains the information on the stoichiometry of the reaction system and is usually timeinvariant. The biological reactions r â‚ ¬ R ^ m are catalysed by the viable biomass, whose concentration is denoted by cx0(t); and the specific reaction rate vector q â‚ ¬R^m is usually a non-linear function of the concentrations. Dâ‚ ¬ R is the renewal (or dilution) rate and u â‚ ¬ R^ n containsthe reactor input/output conditions. There are a large variety of mathematical descriptions of the reaction kinetics available in the literature. A systematic approach is, therefore, necessary to find the best model structure and the best values ofthe model parameters with respect to some imposed criterion. For instance, in terms of model identification, the optimal structure is characterised by minimal correlations between parameters and maximal identifiability properties. In terms of state estimation and control, however, simplicity and (non-)linearity play impo rtant roles.[5] ENZYME CATALYST Most of the rxn that occur in living organism are catalyst by molecule called enzyme. Most enzymes are proteins (certain RNA molecules also act as enzyme). An enzyme is in specific in its action. Many enzymes catalyst only the conversion of a particular reactant to a particular product ;other enzyme catalyst only a certain class of rxn(by ester hydrolysis) . Enzyme speed up rxn rate very substantionally and in their absent most biological rxn occur . The molecule an enzyme act on is called the substrate.the substrate bind to a specific active site on the enzymeso form as enzyme substrate complex. Some physiological poison act by binding to active site of an enzyme,there blocking the action of the enzyme.the structure of an inhibitor may resemble the structure of enzyme substrate .Cyanide act by blocking the enzyme cytochrome oxidase. The single called Escherichia coli, a bacterium that flourished in human colons, contain about 2500 different enzymes .[6] Enzyme Kinetics 1 Michaelis-Menten Kinetics 2.Lineweaver-Burk Kinetics 3. Hanes-Woolf Kinetics 4. Eadie-hofstee 5. Reversible Inhibition[7] K1 k2 E+S ↔ ES ↔ E+P k-1 k-2 E is the free enzyme , S is the substrate, ES is the enzyme substrate complex p is the product. Thp overall rxn is s gives p. The enzyme is assumed in step 1 and rearranged in step 2.Enzymes can catalyze up to several million reactions per second 2.Enzyme rates depend on solution conditions and substrate concentration. Conditions that denature the protein abolish enzyme activity, such as high temperatures, extremes of pH or high salt concentrations, while raising substrate concentration tends to increase activity. To find the maximum speed of an enzymatic reaction, the substrate concentration is increased until a constant rate of product formation is seen. This is shown in the saturation curve on the right. Saturation happens because, as substrate concentration increases, more and more of the free enzyme is converted into the substrate-bound ES form. At the maximum velocity (Vmax) of the enzyme, all the enzyme active sites are bound to substrate, and the amount of ES complex is the same as the total amount of enzyme. However, Vmax is only one kinetic constant of enzymes. The amount of substrate needed to achieve a given rate of reaction is also important. This is given by the Michaelis-Menten constant (Km), which is the substrate concentration required for an enzyme to reach one-half its maximum velocity. Each enzyme has a characteristic Km for a given substrate, and this can show how tight the binding of the substrate is to the enzyme In most experimental studies on enzymes kinetics, the enzyme concentrationis much less than the substrate concentration; [E] [ES]-[E][P] 0=([E] -[E][S])(k[E][S]-[P])-(+)[ES] If [is the initial enzyme concentration than [E]=[E]+[ES].since the conc is [E]during the rxn is generally not known while [E] is known , we replace [E] by [E] The const rate is =- R=[E][S]-[ES] R=[E][S]-([S]+[ES] Since the concentration of the intermediate ES is very small, we have Usually,the rxn is followed only to a few percent completion and the initial rate determined. Setting the product concentration [P]equal to 0 and [S]equal to [S] We get as the initial rate r where the Michaelis Menten const is defined by . The reciprocal of above eq is 1/r= 1/ Equation 2 is the Michaelis Menten eq , and above eq is the Lineweaver Burk eq. One measure r for several [S] values with [E] held fixed. The constant Since [E] is known . strictly speaking r is not the rate at t=0 , since there is a short induction period before steady state condition are establish . Although many exp studies on enzyme kinetic give a rate law in agreement with the Michaelis Menten eq .the mech ‘a is grossly over simplified. For one thing , there is much evidence that , while the substrate is bound to the enzyme , it generally undergoes a chemical change before being released as product . hence a better model is E + S ES ↔ EP ↔ E+ P The above model gives a rate law that has the same form as the Michaelis Menten eq but the const are replaced const with diff significance . Enzyme rxn are quite fast but can be studied using â€Å"classical† methods by keeping [E] and [S]very slow. Lineweaver- Burk Equation The method describe for the determination of is someone complex and therefore simpler method have been devised. Two such method are given below: First method-a convient means of evaluating and is to plot kinetic data as the reciprocals of v and (S) where v velocity and (S) is the total conc of substrate. such a double reciprocal was proposed by Hans Lineweaver and Dean Burk in 1934. If one take the reciprocal of Michaelis Menten eq, the following eq is formed This is known as Lineweaver- Burk Equation. This eq is the form y=mx+b, if one condition the variable to b and 1/(s). When one plots a graph against these two variable , a straight line is obtained . the slop of this line corresponds to and the 1/v intercept corresponds to 1/. Since can be determine from the intercept , the can be calculated . Second method: another graphical method for the measurement of for experimentel data on V as a measure of (S) makes use of the above Lineweaver- Burk Equation . multiplication on sides of the by (S) gives: A plot of verses (S) gives a straight line on axis is and the slope is and can be obtained from intercepy of the slope. A lineweaver burk plots provide a quick test for adhereance to Michaelis Menten eq kinetic and allows easily evaluation of the critical const . it also allow the discrimination between diff kinds of enzyme inhibition and regulation. A disadventure of lineweaver-Burk plot is that a long extrapolation is often require to determine , which corresponds uncertainty in the result. Consequently , other way of plotting the data are sometimes used. Alternate plot are based on Hanes-eq: [s]/v So that v/[s] is plotted against v. The relative merit of the Lineweaver-Burk, Hanes and Edlie-Hoffstee eq for the determination of and are llustrated below in fig. Using the same set of e ixperimental values of v for a series of substrate concentration . it can be seen that the lineweaver-Burk eq gives the unequal distribution of points and greater emphasis to the points at low substrate concentration that are subject to a greater experimental error, whilst the Edlie-Hoffstee eq and a Hans eq gives a better distribution of points. In the case of the Hans plot , greater emphasis is placed on the experimental data at higher substrate 1)Lineweaver plot 2)Hanes plot 3) Eadie-hofstee plot Lineweaver burk, Hanes and Eadie hofstee plot the same set of experimental data of the effect of substrate conc. [S] on the initial rate v of the enzyme catalyst rxn. Reversible Inhibition Now consider the effect of reversibly-binding inhibitors on an enzyme. If an inhibitor binds reversibly at the same site as the substrate, the inhibition is referred to as competitive. If the inhibitor binds to another site on the enzyme, the binding is described as noncompetitive. These two alternative behaviors may be distinguished by their effects on Lineweaver-Burk or Hanes-Woolf plots. If a reversible inhibitor can bind to the enzyme active site in place of the substrate, it is described as a competitive inhibitor. In pure competitive inhibition, the inhibitor is assumed to bind to the free enzyme but not to the enzyme-substrate (ES) complex. The binding is described as shown below: Here Ki is the dissociation constant for the EI complex. EI does not react to form E + P, and the enzyme is unable to bind both S and I at the same time. There are several graphical methods for detecting and analyzing competitive inhibition. The Michaelis-Menten, Lineweaver-Burk, and Hanes-Woolf equations can all be modified to include a term that describes the inhibition by I. Choose one of the cases below to consider each of these in more detail: The Michaelis-Menten equation for competitive inhibition is: The Lineweaver-Burk equation for competitive inhibition is: The Hanes-Woolf equation for competitive inhibition is: Noncompetitive Inhibition If a reversible inhibitor can bind to the enzyme at a site that is distinct from the active site, it is described as a noncompetitive inhibitor. In pure noncompetitive inhibition, the inhibitor binds with equal affinity to the free enzyme and to the enzyme-substrate (ES) complex. The binding is described as shown below: Here Ki is the dissociation constant for either the EI complex or the IES complex. Neither of these complexes can react to form E + P. There are several graphical methods for detecting and analyzing noncompetitive inhibition. The Michaelis-Menten, Lineweaver-Burk, and Hanes-Woolf equations can all be modified to include a term that describes the inhibition by I. Choose one of the cases below to consider each of these in more detail: The Michaelis-Menten equation for noncompetitive inhibition is: The Lineweaver-Burk equation for noncompetitive inhibition is: The Hanes-Woolf equation for noncompetitive inhibition is: Limiting Kinetics of Enzyme-Catalysed Reactions At very low concentrations of substrate many enzyme-catalysed reactions display approximately second-order kinetics, with rate given by the following equation: v = kA [E]0 [A] . . . . . . . in which the symbol kA (or, in general, kR for a reactant R) is the apparent second-order rate constant or specificity constant and [E]0, which may also be written as [E]t or [E]stoich, is the total or stoichiometric concentration of catalytic centres. The rationale for the subscript 0 is that the total enzyme concentration is normally the concentration at the instant of mixing, i.e. at time zero. Conversely, at very high substrate concentrations the same reactions commonly display approximately first-order kinetics (zero-order with respect to substrate): v = k0 [E]0 . in which k0, which may also be written as kcat is the apparent first-order rate constant. Although these limiting types of behaviour are not universally observed, they are more common than Michaelis-Menten kinetics)and provide a basis for classifying inhibitory and other effects independently of the need for Michaelis-Menten kinetics. The quantity k0[E]0 is given the symbol V and the name limiting rate. It is particularly useful when k0 cannot be calculated because the total catalytic-centre concentration is unknown, as in studies of enzymes of unknown purity, sub-unit structure and molecular mass. The symbol Vmax and the names maximum rate and maximum velocity are also in widespread use although under normal circumstances there is no finite substrate concentration at which v = V and hence no maximum in the mathematical sense. The form Vmax is convenient in speech as it avoids the need for a cumbersome distinction between capital V and lower case v. When a true maximum does occur the symbol vmax (not Vmax) and the name maximum rate may be used for the true maximum value of v but care should be taken to avoid confusion with the limiting rate. Enzyme Mechanism: Enzyme kinetic studies,together with the other typeof investigation have led to inside into the way in which enzyme exert their catalytic action.aspects of this are of special interest . This specificityof enzymes is explained in terms of the an elaborating of Fischers â€Å"lock and key†which is concerned with the way in which an enzyme and the substrate fixed together in forming a Enzyme substrate complex and in undergo subsequent rxn . the second aspect is the very high effectiveness of enzyme in comparison with other catalyst. the high effectiveness of catalyst almost always is associate with a low energy of activation for the rxn. in some cases the effect has been attributed to the fact that the enzyme is acting as a bifunctional catalyst, in tha two catalytic group are presentside by side at the active centre. Transition state : When a chemical reaction occurs, the energy content of the reacting molecule or atom increases. This is why most chemical reactions, whether they release heat or absorb heat, happen faster as the temperature is raised. The high-energy state of the reactants is called the transition state. For example, in a bond-breaking reaction, the transition state may be one where the reacting bond, although not completely broken, is vibrating at a frequency high enough that it is equally likely to split apart as to reform. Forming reactants or products results in the loss of energy from the transition state. This principle is shown in Figure 1 , where the increased energy of the transition state is represented as a hill or barrier on the energy diagram. Catalysts reduce the height of the barrier for achieving the transition state. General Catalytic Mechanism Catalysed reaction occur by a wide variety of mechanism.There is however one pattern that applies to a no of single substrate rxns catalysted by surfaces,enzymes, acids and bases. It is useful to consider this schmene of rxn first show as to appreciate the similarities that exist between certain rxn that are catalysted by different type od catalyst. The rxn schme: C + S ↔ X + Y X + W ↔ P + Z Here C represent the catalyst and s is the substrate; X and Y are intermediate , the first of which undergoes a second rxn with a species W to give final product or products P together with the addition substance Z. This scheme shows only the kinetically significance reactions; the substate Y and Z undergo other process that do not have any effect on yhe kinetic behaviour. To simplify the treatment it is assumed that the second rxn does not in the reverse direction ; this can b ensured if the product P is removed as far as it is formed. In surface catalysis X is an adsoption complex, Y and W are non exitance. The const in this case are first order rate const, while is the second order const. In catalysis by acid and base however Y and W play important role. Thus i c is an acid catalyst, rxn 1 involces the transfer of a proton to S,so that Y is the base conjugate to the acid C. In acid catalyst the intermediate X is the protonated substrete SH+ and a rxn 2 is proton is transferred to a species W. The species W therefore has basic properties and it may b molecule of a solvent and a solute. For eg It may be the species Y formed in 1 step . we will see that the kinetic behaviour depends in an important way on wheather the intermediate X transfers its proton to solvent molecule or to a solute molecule. Conversely in base catalyst Y is the acid conjugate to the base C.the intermediate X is the substrate Molecule minus a proton., and in rxn 2 it accepts a proton from W.again we have a solvent molecule or a solute molecule.in some situations a rate with which a intermediate X undergoes rxn 2 may be sufficiently slow that the first rxn may b regarded as being at equilibrium.the exact condition for this is [W][X][Y].since this case corresponds to Arrhenius concept of an intermediate in eq with the reactants, such intermediate have being called Arrhenius intermediates. The converse case is that the condition is [X][Y]the concentration of X is small and the steady state treatment may be appliedto it. Intermediate of this kind have been called Vant Hoff intermediates. If neither of this of this extreme condition applies , the kinetic situation is more complicated , and the appropriate differential eq have to be solved. Only the equolibium and steady-state treatments are considered here. Equilibrium Treatment : Arrhenius intermediates In this case the equation : Applies. However , the concentration of C and S do not correspond necessary to yhe initial concentration [C] and [S]. Since appreciable amount of C and S have been used to form a intermediate X. These initial concentration may be expressed as [C]=[C] + [S] [S]= [S] + [X] As long as attention is confined to initial rates. Eq a become This is quadratic in [X] and can be solve for [X]. Yhen the expression for rate equal to k[X][W] , can be written down. However it os, more useful to consider two special cases. Case 1: if the initial conc of the substrate is much greayer than that of yhe catalyst, that is, if [S][C], it follows that [S] [X] is very close to [S], since [X] cannot exceed [C]. Eq b there fore reduces to : And thus The rate of rxn therefore V=[X][W]= This rate eq correspond toa variation of rate of all type represent .At lower substrate conc , when K[S][Y], the rate become independent of [S], as long as the condition [S]>>[C] holds, however the rate varies linear with [C]. This type of behaviour is characteristic or single-substrate rxn on surfaces and of enzyme rxn. For both of these the species Y and W are nonexistence and eq c become: The eq is also eq to the Michaelis Menten eq for enzyme rxn. This eq usually written Where is the Michaelis const , is equal to 1/k in the present treatment. In rrn catalysed by acid and base it will be seen that the rate remain linear with the substrate concentration ; this is because of the special type of equilibrium that are rapidly established in the sol. Case 2: on the other hand , if the catalyst is greatly in excess of the substrate, that is [C]>>[S] eq a reduces to And the rate of rxn is The rate now varies linearily with the concentration of substrate , but the variation with the catalyst concentration . (b)The rate of reaction as a function of substrate conc for the case in which [S]>>[C] (a) rate of rxn as a function of catalyst concentration for the case[C]>>[S] Steady-state Treatment:Van,t hoff intermediate If the condition [W]>> applies, the concentration of X is small and the steady state treatment is available. The steady-state is substitution of [C] -[X] for [C] and of [S]-[X] for [S} gives since [X] is very small the term in can be neglected ; with its approximation above eq gives the rate is therefore this eq again indicates that at low conc of either catalyst or substrate the rate is proportional to either [C] or [S] ; at a higher concentration of either the rate become independent of that concentration . in catalyst by surface and enzymes , W and Y are nonexistence and the rate eq become An eq of essentially this form was first derived by Briggs and Haldane for enzyme reaction Catalyst By Enzyme Catalysis by enzyme , the biological catalyst , is much more specific than that by acids and bases. soe enzyme shows absolute specificity ; an eg is urease, which only the catalyzed of Urea. A lower degree of specificity is shown by such enzyme as the proteolytic enzymes, which catalyst the hydrolysis of the peptide linkage provided that certain structural condition are specified in the neighbourhood of the linkage.; this is known as group specificity. many enzyme exhibit stereochemical specificity, in that the catalyze the rxn of one stereochemical form and not the other.the proteolytic enzyme.The enzymes are protein but may be associated with non protein substance that essential to the action of enzyme.the action of enzyme shows some resemblance to the catalytic action of acids and bases but is more complicated. the present treatment of enzyme kinetics is confined to the influence concentration, ph, and temperature and to some brief comments about enzymes mechanisms. Measurement of the kinetics of biological systems at elevated temperatures utilizing flow techniques Continuous flow-type reactors have been used to study the kinetics of biological systems for quite some time. For continuous media sterilization, tubular flow reactors are particularly useful being simple in character and easy to control. However, one aspect quite often neglected in sterilization calculations is the residence time distribution of the reactor system. Serious errors in estimating the degree of bacterial destruction can be encountered if the residence time distribution is neglected; especially when a high degree of destruction is desired. This paper reports a study made to characterize and use the residence time distribution of a tubular reactor in the interpretation of high-temperature, short exposure time data for inactivation of Bacillus stearothermophilus spores. Mathematical models accounting for the residence time distribution of the tubular reactor have been proposed and employed to obtain high-temperature death-rate data.[14] Result Since enzymatic reactions are so important to biological chemical reactions, it is of great interest to be able to model them. By use of the study of chemical kinetics, it is possible derive rate equations for the steps involved in an enzymatic reaction. These rate equations are differential equations and can be used to model theconcentrations of each compound in the system. However, this system of differential equations is hard to determine experimentally because of the difficulty of determining the rate equations into theMichaelis-Menten enzyme equation. Many benefits stem from this transition. One benefit is the fact that it is now easy to determine the constants related to the enzyme equations. However, how do we know the Quasi-Steady-State Assumption is valid? It seems reasonable from a physical argument. Byuse of dimensional analysis, we can give a more rigorous mathematical argument for the Quasi-Steady-State Assumption. The Michaelis-Menten enzyme equation is very important i n the study of cellular systems by allowing a model that can be easily derived through experimentation.

Critical Evaluation of Stone Cold by Robert Swindells Essay -- English

Critical Evaluation of Stone Cold by Robert Swindells A novel that I have read recently is "Stone Cold" by Robert Swindells. In this novel there are two main characters called Link and Shelter. These characters have very different personalities. I intend to consider the ways in which the author has created these two very different personalities and will explain my reaction to each of them. This novel tells both sides of one story, Links side and Shelters side. Link is a 16year old boy that left home because of family troubles and Shelter is a 47year old man who was discharged from the army on medical grounds and doesn't agree with this. He thinks it is his duty to get rid of the homeless. Link moved to London to get away from it all (his family) and became homeless. Shelter doesn't like the homeless, he just thinks they are a "waste-of-space" Shelter begins to bribe them into going back to his flat where he intends to kill them! Shelter kills many of Links friends and Link begins to wonder why they are all going missing. He does some detective work and then the truth is finally revealed. In this novel Link is one of the main characters. During this novel we are made to sympathise with Link. One of the ways in which we are made to sympathise with him was when his stepfather Vince treated him unfairly "slapping him about". This did not happen on only one occasion in fact it happened everyday: "I'd been with my mates, he locked me out the house". Even although this was not Vince's house he still thought he had the authority over Link and his mother to do this. This also showed how much Vince disliked Link. Another way in which we are made to feel sorry for Link was when link was homeless and could... ...lpless person didn't have a clue what they were getting themselves into. Link and Shelter are the complete opposite of each other. Link is a very caring character that hasn't really achieved anything in life, whereas Shelter is a cruel, heartless person who has experienced military work in life. In conclusion I think Shelter is a horrible man. I feel sorry for Shelter because I think he feels he didn't achieve in life because he was dismissed from the army and he is coming back by killing the homeless. On the other-hand I think Link is a very kind and lonely person. No matter how poor he was he always helped his friends. I also feel sorry for Link, his family disowned him and he has no real friends. I thought this novel was a great read. It made me realise how hard and dangerous it is for the homeless to survive and also what a lonely life they lead.

After Hope And Change

Despite winning reelection, President Obama had joined a group of three to her previous incumbents (Eisenhower, Wilson, and Clinton) who had all entered office origin anally with a united government in their very first term and then won reelection with a did vided government. Obama had lost his seats on the House of Representatives. Will on was the only other president in history to lose more seats than President Obama. The novel speaks on how five incumbent presidents since 1 896 had lost reel action and then begins to explain why those same factors didn't apply to President Obama.Us memorize the four arguments the authors make. There are multiple reasons Barrack Beam's 201 2 presidential reelection was slight victory although he won reelection, it was fairly close in the polls. The opponent NT Mitt Rooney didn't have a proficient performance when he had to present his plan NSA on if he was to be elected, not only did this show some of his flaws as a speaker but al so as a candidate . Rooney had way too many weak points that Obama was able to TA eke advantage of to convince the American people he was still their best option. R money pushed his few advantages way too far.He stayed on one topic the entire Tim e and would mindlessly talk about that same subject, which was a flaw on his part especial Y close to the elections. If Mitt Rooney had given better speeches and realized some of his mistakes before elections, the outcome may have been different in 2012. Summarize the arguments that the authors made concerning the results from the 2012 elections and what they may tell us about the 2016 elections. The first point made by the authors uses statistics to predict that the president till election in 2016 will be a battle for the most swing states.In 2012, Barrack Obama had gained the states that he won in his previous election. These states had also been the as me couple dates that the last three democratic presidential candidates had also won as well. Rooney had also won the states that previous republican candidates had won as well. There were only n,vow states that had changed between the 2008 and 2012 elections. Became use of how the republicans have lost the last two presidential elections (Including the 201 2 elections), they have some serious work to do and they must pull off swinging multiple s dates in the 201 6 elections (something that hasn't happened in half a century).The second point of the chapter speaks on the changes in demography. In bet when the ears of 2008 and 201 2 percentages of the ethnic groups that vote democrat increased very high. These voter increases were very noticeable with an increase in youth h support, especially for democrats. Without any explanation the numbers of ethnic race s that vote republican dropped. The very republican votes that dropped during the elect On W ere surprisingly white males. This made an impression that the youth were in co melt support of Obama. This is important because in the futu re it would seem that they will go on to support the democrats.At the same time it is very possible that the turn UT was quite low in the 201 2 race turnout for many favorable republican categories w as quite lower than expected. Minorities refused to vote for Mitt Rooney simply because SE their identity with him was almost nonexistent if he would become the next preside .NET. This very fact coupled those not in support of Obama, this led to people not voting at all, which severely hurt the republican parry's chances of winning the race. Minor ties can always change their mind on who they will vote for or even if they should vote at all depending on the status of the economy at that time.That very fact may lead o the republicans doing better with appeal to the minorities in the 2016 elections, a ND they could sway them, especially if no democrat could like President Obama. The final point discusses the reasoning of both democrats and republicans. D emaciates have always been focused on social justice, and the use of more federal govern moment plans, and redistributions policies. Democratic policies will be in full support of those whose jobs are given to by the government and those who receive benefits FRR mom the government (welfare, healthcare, etc).Meanwhile, the republicans are focuses on lowering taxes from the government, dividend liberty in the economic arena, a achieving a small federal government. The Democrats Will have those who chi goose to receive benefits from the government policies gravitate to their side, while re publicans will always focus on bringing rich businessmen who support themselves to the Eire side. Many republicans have joined the party because they are tired of an overpower erring federal government and paying high taxes.Chapter 2 Questions What were the issues and characteristics of politics arising from President b mama's first term hat figured in the 201 2 election. Give brief summaries Of what was involved I n these issues and the positions that Democrats and Republicans held in order to demonstrate t hat you have a general understanding of these issues. The unemployment rate during the recent recession was very shaky going up and down during the years of 2010, 2011 , 2012. There was a brief boom of jobs created during this period, this would end up disintegrating within a short period of time.Demo rats had originally said that during the time of President Beam's first term that he ha d actually ordered the high unemployment rate in America. Republicans were found to have said that because of how slowly the improvement of the economy has been, press dent Beam's policies in office slowed down the natural progress of improving the economy. This made their case for the recession being one of the longest ever. The flourishing of the nationwide deficit and debt rolled over onto President Beam's first term in 2008. In the â€Å"Obama era†, the national debt never fell below the amount off trillion dolla rs.The average in the first term was 1. 33 trillion dollars. This peer entangle was appalling because no one could have possibly predicted such a number a coo plea yea RSI before Beam's election. The overall federal spending amount of the GAP ha d increased nearly 5% from 2007 to 2012. Republicans went on to say that Barrack Obama presidency was the true cause of all of the spending. To counter that statement NT, Democrats had responded saying that an increase in the deficit was just as UN avoidable as the last President who happened to be a republican (George W.Bush) who ha d originally put America in this very predicament. Political popularization had become a big problem during Beam's first term. In such a divided government, reaching an agreement between both democrats and re publicans was extremely difficult. What did the 2010 midterms reveal about politics nationally? It was revealed that the American people were heavily in support of Republican NSA Simply because President Be am's first term had not been the best in the â€Å"popularity y contest†. It exposed many of the ideologies of the American people with the unveiling of a now completely divided government.How did President Obama improve his political position leading into the election? President Obama began to improve his political position by lowering the socio I security tax by two percent of the original price in December of 201 1. This was to been fit lower income workers whose payroll tax was more than their income tax. Such a pop were play in office proved that Obama was in support Of the lower and middle classes and that unlike republicans the upper class wasn't a priority. The Occupy Wall Street Movement that began in mid September 2011 also boo Existed President Obama.The movement/ strike blamed the top â€Å"one percent' of the country (Rich) for all the problems with the current economy. The movement also bell paved that he 1% has benefited while the rest of the country is in suf fering. Obama had decided that he was indeed support of those who weren't wealthy which politically is a strong decision because it accounts for 99% of the nation President Obama benefited from the reports of his speech after the beginning Eng of The Occupy Movement stating that the unemployment rate had actually fallen fro m 9% to 8. % within the time period of early December 2011 to late March 2012. Chapter 3 Questions What reasons do the authors give as to why it was unlikely that Mitt Rooney would win the nomination? It was very unlikely that Mitt Rooney would end up winning the nomination f president because he was seen as â€Å"an uncomfortable fit† because he only fit n one of the three factions of the GOP.He appealed to many of the old school republicans with his strong corporate background in big business, but was considered to be very weak with the other two factions of the GOP (social and Christian conservatives care about t he laws of abortion, same sex marriage, and other concerns). The book describes two structural changes that had an impact on the amino Zion process: Republicans limiting winner aka all primaries until after April 1 and the changes in the laws regulating campaign finance. Summarize both changes and the effect they ha d on the nomination campaigns.

Five Factor Theory

One of the long held goals of psychology has been to establish a model that can conveniently describe human personality and disorders therein, with the intent to use this model in the remedying of personality disorders and improving general understanding of personality. Currently, a handful of models have risen to prominence, and have thus far stood the test of time. Some models are more generally accepted than others. Support for some models seems to come and go in cycles. One of the more prominent models in contemporary psychology is what is known as the five-factor model of personality. This theory incorporates five different variables into a conceptual model for describing personality. These five different factors are often referred to as the â€Å"Big 5†. The five-factor theory is among the newest models developed for the description of personality, and this model shows promise to be among the most practical and applicable models available in the field of personality psychology. Thorough critical attention is given to the proposal that the five-factor model is in fact a great theory. As it became evident to many psychologists that, mathematically, combinations of five factors were useful in describing personality, there was a need to clearly define what these factors were. Indeed, this process led to some dissent in the ranks. One dissenter from the five-factor theorists was renowned psychologist H. J. Eysenck. Eysenck felt that, due to overlaps in the five factors and their correlates, in fact a three-factor model was more appropriate and accurate. His theory is called the PEN model (which stand for psychoticism, extroversion, neuroticism), or sometimes is even shortened to the two factor E-IN model (extroversion-introversion, neuroticism). Many psychologists support Eysenck's PEN model. However, of the major â€Å"factor-analytic models†¦ the Big Five dominates the landscape of current psychological research† (Ewen, 1998, p. 141). Through extensive debating and experimenting, there is currently a general consensus in the realms of scholarly psychology as to the identity of the five factors, and their basic interpretations and values to analysis of personality. The five factors are extroversion-introversion, neuroticism, agreeableness, conscientiousness, and openness. Extroversion has long been one of the traits that has appeared in factor-analytic models, and is one of the two traits to appear in both the five-factor model and Eysenck's PEN and E-IN models. Extroversion also is sometimes referred to as social adaptability, though the popularity of this term seems to be waning. Extroversion is defined as a trait characterized by a keen interest in other people and external events, and venturing forth with confidence into the unknown. Neuroticism is the other trait to play a role in most of the contemporary factor models for personality. In some studies, adjustment is examined as a factor, instead of neuroticism. In this case, higher scores will indicate a positive result, consistent with the other four factors. This is because the term neuroticism has an inherent negative denotation (Bradshaw, 1997). The bases of neuroticism are levels of anxiety and volatility. Within these bounds, neuroticism is a dimension of personality defined by stability and low anxiety at one end as opposed to instability and high anxiety at the other end. Openness, agreeableness, and conscientiousness are all terms with which most people outside the realm of psychology are familiar. In general, openness refers to how willing people are to make adjustments in notions and activities in accordance with new ideas or situations. Agreeableness measures how compatible people are with other people, or basically how able they are to get along with others. Conscientiousness refers to how much a person considers others when making decisions. As with the two factors in the big five from Eysenck's E-IN, these three are also placed on sliding scales. These three scales, like neuroticism and extroversion, slide between their limits to give a clear picture of personality. The limits of these scales give a clear idea of their applications and are defined as trusting and helpful versus suspicious and uncooperative (agreeableness), hard working and reliable versus lazy and careless (conscientiousness), and nonconformist and creative versus conventional and down-to-earth (openness). Never the less, there are many other theorist who have evaluated the five factor theory in a much boarder aspect. These researchers began by studying all known personality traits and then factor- analyzing hundreds of measures of these traits in self-report and questionnaire data, peer rating and objective measures from experimental settings in order to find the basic, underlying factors of personality. The big five factors of personality are five broad domains or dimensions of personality which have been scientifically discovered to define human personality at the highest level of the organization. These five over-arching domains have been found to ontain and subsume more or less all known personality traits within their five domains and to represent the basic structure behind all personality traits. They have brought order to the often-bewildering array of specific lower level personality concepts that are constantly being proposed by psychologists, which are often found to be overlapping and confusing. These five factors provide a rich conceptual frame work for integrating all the research fi ndings and theory in personality psychology. Three sets of researchers have worked independently for decades on this problem and have indentified generally the same Five Factors. They are Goldberg at the Oregon Research Institute, Cattell at the University of Illinois, and Costa and McCrae at the National Institutes of Health. These three sets of researchers used somewhat different methods in finding the five traits, and thus each set of five factors has somewhat different names and definitions. However, all three sets have been found to be highly inter-correlated and factor-analytically aligned. The Big Five Factors are commonly known as Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism, also Known as OCEAN or CANOE. OPENNESS Openness is a general appreciation for art, emotion, adventure, unusual ideas, imagination, curiosity, and variety of experience. The trait distinguishes imaginative people from down-to-earth conventional people. People who are open to experience are intellectually curious, appreciative of art, and sensitive to beauty. They tend to be, compared to closed people more creative and more aware of their feeling. They are more likely to hold unconventional beliefs. In addition, people with low scores on openness tend to have more conventional, traditional interest. They prefer the plain, straight forward and obvious over the complex, ambiguous and subtle. They may regard the arts and sciences with suspicion, regarding these endeavours as abstruse or of no practical use. Close people prefer familiarity over novelty. They are conservative and resistant to change. CONSCIENTIOUSNESS Conscientiousness is the tendency to show self-discipline, act dutifully and aim for achievement. The trait shows a preference for planned rather than spontaneous behaviour. It influences the way in which we control, regulate, and direct our impulses. Conscientiousness includes the factor known as Need for Achievement or NAch. It is obvious that the benefits of conscientiousness are high. Conscientious individuals avoid trouble and achieve high levels of success through purposeful planning and persistence. They are also positively regarded by others as intelligent and reliable. On the negative side, they can be compulsive perfectionists and workaholics. EXTRAVERSION Extraversion is characterized by positive emotions, surgency and the tendency to seek out stimulation and the company of others. The trait is marked by pronounced engagement with the external world. Extraverts enjoy being with people and are often perceived as full of energy. They tend to be enthusiastic, action oriented individuals who are likely to say â€Å"I most certainly will! † or â€Å"Come on let’s go! † to opportunities that will excite them. When placed in groups they are likely the first to talk, and assert themselves, just to draw attention to themselves. However, Introverts lack the exuberance, energy and activity levels of extraverts. These individuals tend to be quiet, low-key, deliberate, and less involved in society. Their lack of social involvement should not be interpreted as shyness or depression. Introverts simply need less stimulation than extraverts and more time alone. AGREEABLENESS Agreeableness is a tendency to be compassionate and cooperative rather than suspicious and antagonistic towards others. The trait reflects individual differences in general concern for social harmony. Agreeable individuals value getting along with others. They are generally considerate, friendly, generous, helpful and willing to compromise their interests with others. Agreeable people also have an optimistic view of human nature. They believe people are basically honest, decent and trustworthy. On the other hand, disagreeable individuals place self-interst above getting along with others. They are generally unconcerned with others’ well being and are less likely to extend themselves for other people. Sometimes their scepticism about others’ motives causes them to be suspicious, unfriendly and uncooperative. NEUROTICISM Neuroticism is the tendency to experience negative emotions, such as anger, anxiety or depression. Emotional instability it is sometime called. Individuals who score high in neuroticism are emotionally reactive and vulnerable to stress. They are more likely to interpret ordinary situations as threatening and minor frustrations as hopelessly difficult. Their negative emotional reactions tend to persist for unusually long periods of time, which means they are often in a bad mood. These problems in emotional regulation can diminish the ability of a person scoring high on neuroticism to think clearly, make decisions and cope effectively with stress. However, on the other end of the scale, those who score low in neuroticism are less easily upset and are less emotionally reactive. These individuals tend to be calm, emotionally stable, and free from persistent negative feelings. Freedom from negative feelings does not mean that low scorers experience a lot of positive feelings. Frequency of positive emotions is a component of the Extraversion domain.

10 Radon Facts (Rn or Atomic Number 86)

10 Radon Facts (Rn or Atomic Number 86) Radon is a natural radioactive element with the element symbol Rn and atomic number 86. Here are 10 radon facts. Knowing them could even save your life. Fast Facts: Radon Element Name: RadonElement Symbol: RnAtomic Number: 86Element Group: Group 18 (Noble Gas)Period: Period 6Appearance: Colorless Gas Radon is a colorless, odorless, and flavorless gas at ordinary temperature and pressure. Radon is radioactive and decays into other radioactive and toxic elements. Radon occurs in nature as the decay product of uranium, radium, thorium, and other radioactive elements. There are 33 known isotopes of radon. Rn-226 is the most common of these. It is an alpha emitter with a half-life of 1601 years. None of the isotopes of radon are stable.Radon is present in the Earths crust at an abundance of  4 x10-13  milligrams per kilogram. It is always present outdoors and in drinking water from natural sources, but at a low level in open areas. Its mainly a problem in enclosed spaces, such as indoors or in a mine.The US EPA estimates the average indoor radon concentration is 1.3 picocuries per liter (pCi/L). Its estimated approximately 1 in 15 homes in the US has high radon, which is 4.0 pCi/L or higher. High radon levels been found in every state of the United States. Radon comes from the soi l, water, and water supply. Some building materials also release radon, such as concrete, granite countertops, and wall boards. Its a myth that only older homes or ones of a certain design are susceptible to high radon levels, as the concentration depends on many factors. Because it is heavy, the gas does tend to accumulate in low-lying areas. Radon test kits can detect high levels of radon, which can generally be mitigated fairly easily and inexpensively once the threat is known. Radon is the second leading cause of lung cancer overall (after smoking) and the leading cause of lung cancer in non-smokers. Some studies link radon exposure to childhood leukemia. The element emits alpha particles, which are not able to penetrate skin, but can react with cells when the element is inhaled. Because it is monatomic, radon is able to penetrate most materials and disperses readily from its source.Some studies indicate children are at higher risk from radon exposure than adults, probably because they have more rapidly dividing cells, so genetic damage is more serious. Also, children have a higher metabolic rate.The element radon has gone by other names. It was one of the first radioactive elements that was discovered. Fredrich E. Dorn described radon gas in 1900. He called it radium emanation because the gas came from the radium sample he was studying. William Ramsay and Robert Gray first isolated radon in 1908. They named the element niton. In 1923, the name changed to radon, after radium, one of its sources and the element involved in its discovery. Radon is a noble gas, which means it has a stable outer electron shell. For this reason, radon does not readily form chemical compounds. The element is considered chemical inert and monatomic. However, it has been known to react with fluorine to form a fluoride. Radon clathrates are also known. Radon is one of the densest gases and is the heaviest. Radon is 9 times heavier than air.Although gaseous radon is invisible, when the element is cooled below its freezing point (−96  °F or −71  °C), it emits bright luminescence that changes from yellow to orange-red as the temperature is lowered.There are some practical uses of radon. At one time, the gas was used for radiotherapy cancer treatment. It used to be used in spas, when people thought it might confer medical benefits. The gas is present in some natural spas, such as the hot springs around Hot Springs, Arkansas. Now, radon is mainly used as a radioactive label to study surface chemical reactions and to initiate react ions.While radon is not considered a commercial product, it may be produced by isolating gases off of a radium salt. The gas mixture can then be sparked to combine hydrogen and oxygen, removing them as water. Carbon dioxide is removed by adsorption. Then, radon may be isolated from nitrogen by freezing out the radon. Sources Haynes, William M., ed. (2011). CRC Handbook of Chemistry and Physics (92nd ed.). Boca Raton, FL: CRC Press. p. 4.122.

Army out of Vieques essays

Army out of Vieques essays Rafael Torres, a former security guard at the U.S. Navy base in Vieques, said he still hears noises in his head. A sound like the fighter jet that in 1995 hurled two cement-filled projectiles a few feet from where he was standing (ROSS A10). "The other day I was sleeping in my armchair, and I dove on the floor when I heard airplanes buzzing in my ears," said Torres (qtd in ROSS A10), 49, who has since retired with a disability pension because of psychological trauma from the accident. He said one bomb struck the three-story observation post he was guarding, crashing through the top two floors. The second landed feet away from where he stood, spewing chunks of cement. Torres didn't realize this at the time, but this narrow miss foreshadowed a much more serious accident (ROSS A10). Months later on April 19,1999, one of Torres's co-workers, David Sanes Rodriguez was pulling duty at the same post when a Navy F-18 dumped two 5,000-pound bombs about 1.9 miles off course. Unlike the inert practice bombs Torres encountered, these projectiles packed lives explosives. Sanes was killed, and four other base employees were injured. This incident has stirred widespread political opposition to the Navy's 60 year hegemony over this Puerto Rican island-municipality. Now, the pentagon is in danger of losing its premier naval training facility. The Atlantic Fleet Weapons Training Facility in Vieques, which is judged by military analysts to be an irreplaceable national security asset and the only site where the military can stage integrated sea and air training (The Pentagon A32). Puerto Rico has been a United States territory for 102 years, and for 61 of those years the U.S. navy has used the Puerto Rican island of Vieques as a practice bombing range. United States troops have trained on the island of Vieques, Puerto Rico, since World War II. Seventy percent (about 22,000 of 33,000 acres) of Vieques is controlled by the U.S. Navy. ...

A Schools Website Makes an Important First Impression

A Schools Website Makes an Important First Impression Before a parent or student physically sets a foot into a school building,  there is an opportunity for  a virtual visit. That virtual visit takes place through a schools website, and the information that is available on this website makes an important first impression. That first impression is an opportunity to highlight the schools best qualities and to show how welcoming the school community is to all stakeholders-parents, students, educators, and community members. Once this positive impression is made, the website can  provide a wide variety of information, from posting an exam schedule to announcing an early dismissal because of inclement weather.  The website can also effectively communicate the schools vision and mission, the qualities, and the offerings to each of these stakeholders. In effect, the school website presents the personality of the school. What Goes on the Website Most school websites have the following basic information: Calendars for school activities, school schedules, and bus schedules;  Policy statements (ex: dress code, Internet use, attendance);School news on individual student achievements or group achievements;Information on the school learning activities including academic requirements, course descriptions, and prerequisite course work;Information on school extra-curricular activities (ex: clubs and athletic program);Links to teacher web pages and also staff and faculty contact information; Some websites may also provide additional information including: Links to organizations or websites outside the school that support the schools academic program (ex: College Board-Khan Academy)Links to software that  contain student data  (Naviance,  Powerschool, Google Classroom)Links to forms (ex: permission slips, course registration, attendance waivers, transcript requests, free and reduced lunch) that can reduce the  costly reproduction of paper copies;Board of Education resources such as contact information for board members, minutes of meetings, agendas, and meeting schedules;District policies, such as those policies on data privacy;Photos of students and faculty;A forum or discussion page for  teachers, administrators, students, and parents to exchange information such as news and calendars of events;Links to school social media accounts (Facebook, Twitter, etc). Information placed on the school website will be available 24 hours a day, 7 days a week, 365 days a year. Therefore, all the information on the school website must be timely and accurate. Dated material should be removed or archived. In real time information will provide stakeholders confidence in the information posted.  Up to date information  is particularly important for teacher websites that list assignments or homework for students and parents to see. Who Has Responsibility for the School Website? Every school website must be a reliable source of information that is communicated clearly and accurately. That task is usually assigned to a schools Information Technology or IT Department. This department is often organized at the district level with each school having a  webmaster for the school website. There are a number of school website design businesses that can provide the basic platform and customize the site according to a schools need. Some of these include Finalsite, BlueFountainMedia,  BigDrop, and SchoolMessenger. Design companies generally provide the initial training and support on maintaining the school website. When an IT Department is not available, some schools ask a faculty or staff member who is particularly technologically savvy, or who works in their computer science department, to  update their websites for them.  Unfortunately, building and maintaining a website is a  large task that can take  several hours a week. In such cases, a more collaborative approach of assigning responsibility for sections of the website might be more manageable. Another approach is to use the website as a part of the school curriculum where students are given the task of developing and maintaining  portions of the website. This  innovative approach benefits both the students who learn to work collaboratively in an authentic and on-going project as well as educators who can become more familiar with the technologies involved. Whatever the process for maintaining the school website, the ultimate responsibility for all content must lie with one  district administrator.   Navigating the School Website Possibly the most important consideration in designing the school website is the navigation. The navigation design of a school website is particularly important because of the number and variety of pages that may be offered to users of all ages, including those who may be unfamiliar with websites entirely. Good navigation  on a school website should include a navigation bar, clearly defined tabs, or labels that clearly differentiate the pages of the website. Parents, educators, students, and community members should be able to travel throughout the entire website regardless of the level of  proficiency with websites.   Particular attention should be given to encouraging parents to use the school website. That encouragement might include training  or demonstrations for parents during school open houses or parent-teacher meeting. Schools could even offer technology training for parents  after school or on special evening activity nights. Whether it is someone 1500 miles away, or a parent living down the road, everyone is afforded the same opportunity to see the schools website online.  Administrators and faculty should see school website as the front door of the school, an opportunity to welcome all virtual visitors and make them feel comfortable in order to make that great first impression. Final Recommendations There are reasons to make the school website as attractive and professional as possible. While a private school may be looking to attract students through a website, both public and private school administrators may be seeking to attract high-quality staff who can drive achievement results. Businesses in the community may want to reference a schools website in order to attract or expand economic interests. Taxpayers in the community may see a well-designed website as a sign that the school system is also well-designed.

Discuss Ghostwatch in relation to broadcasting's ideology of Essay

Discuss Ghostwatch in relation to broadcasting's ideology of 'liveness' and the centrality of liveness to television OR discuss broadcasting's inherent associations with haunting and the uncanny - Essay Example It has a capacity to broadcast a variety of program genres and can adapt to varying domestic and cultural contexts. It likewise shares with radio the capacity to broadcast events to mass audiences as promptly as they happen. This capacity of the television is viewed as characteristic of liveness (Davis, 2007). As society transforms and continuously becomes a witness to various historical and significant national and world events, the television has continued to develop with regard to its evolution from technological hardware transition to digital broadcasting and satellite services. The technological developments in television programming account for the creation of techno-material quality of television image of which liveness is a feature (Bourdon, 2004). This is without due regard to whether the television show was edited prior to the airing or is strictly ‘live.’ The content of television images is also influential to the concept of liveness, in which the television i mages are considered an audiovisual materiality created by technological processes (Davies, 2007). The technical and material quality of television image comprises its quality of liveness, indicating that liveness is a feature of all television images, regardless of whether the show is recorded and/or edited and strictly live (Davis, 2007). The concept of television liveness remains central to an understanding of television in general, despite a decline in the live broadcasting in the recent years (Bourdon, 2000). It is the viewer’s belief in live broadcasting which constitutes liveness, not merely an actual live performance of a show. This belief is influenced by the social context, the tele-visual text, and the audiences’ social characteristics alongside the temporal sequencing of television viewing. Liveness is not limited to the here and now of a television show, but is rather inclusive of edited shows such as non-fiction and non-live, as

Privacy is not the most important right Essay Example | Topics and Well Written Essays - 1000 words

Privacy is not the most important right - Essay Example There was very limited control in the society. However, modern institutions have developed controls that have raised very various privacy concerns. Privacy has become a matter of concern to many thinkers, law makers, human rights activists and other essential policy makers. Despite the significance of the right to privacy and the existing laws supporting it, government agencies, security departments and legislative authorities across the globe have engaged in laws and acts that violate the right to privacy as a basic principle that define human dignity. The guiding principle for security agencies in Britain is that security interests and ensuring stable human security is supersedes the basic right to privacy. The United Kingdom has overemphasized the protection of human security at the expense of the constitutional right to privacy. The installation of public surveillance cameras in major cities and towns in Britain is an example of a major violation of the fundamental right to privacy in the country. As a matter of fact, every individual has something to hide from the public, a fact that may be infringed by the installation of surveillance cameras. It is a universally acknowledged that people should not be allowed to hide under the guise of the right privacy to commit crimes and cause harm to law abiding members of the society. Proponents of this point of view hold that privacy is not one of the most fundamental human rights. Most scholars will concur with my position that, privacy defines comprehensively the right to be left alone and refrain from sharing an individual’s private information with other people. Some of the common issues that are catered for by privacy rights include: individual truths, private matters and issues, individual information as well as ones secrecy. The right to privacy is commonly popular and profound to free people. It offers a significant amount of

After the agreement is reached between him and the customers, to avoid the impurities that would have been there if the work was done on much higher speed, Tim should instruct the process to be done with the appropriate speed to eliminate impurities (Wallace, 1998). In the case where Arnold learns that Tim substituted the old components he should explain that it was an unintentional negligence which did arise due to shortage in machine supply, additionally the customer was very clear on the time factor which was a must to be meet. Tim should say that he has taken matters to have periodic inspections to avoid such future happenings.

Functions of Public Relations Essay Example | Topics and Well Written Essays - 1250 words

Functions of Public Relations - Essay Example The two main functions of Public Relations are Organizational and Societal. The scope of Organizational Public Relations covers all the internal processes. This is the representation of the company in relation to specific groups or other organizations. This is directed to both internal and external groups. An example of an internal group is the employee base of the company and one example of an external group is the media. With Organizational Public Relations, the focus is on knowing and addressing the needs of the company or the issues in the organization itself and relating this to how other organizations outside the company affect these needs and how they can contribute to the resolving of issues or problems. Societal functions of Public Relations on the other hand, deal with external processes or how the company reaches out to society. This includes activities or strategies directed towards the public with the intention of addressing their needs and interests. The societal functi ons have intentions of both serving the objectives of the company and getting information from the public regarding their needs and concerns so these matters may be properly attended to. I have cited two specific functions each for both organizational and societal public relations. A. Organizational 1. Employee Relations This is part of the organizational function of Public Relations as the purpose of this strategy is to maintain a healthy employee-employer relationship with the aim of improving productivity, increasing morale and providing motivation (Employee Relations, 2001). Information is given to the employees regarding the goals, objectives and the current status or performance of the company. It is also a venue for the airing of grievances or concerns. It is usually done through internal communications like company newsletters or briefings, dialogues, recognition programs and other company events. 2. Media Relations The media has been the main instrument for Public Relations campaigns or programs. It is the means by which information which the organization needs and wants to convey to the public, is disseminated. Media Relations is establishing an affiliation with the media by consistently responding to them and reaching out to them. Public Relations, in this aspect acts as a representation of the company to the media. Media relations is part of the organizational function because it addresses the objectives of the company by establishing close cooperation with another group or entity which is very instrumental to the achievement of the company's goals. B. Societal 1. Marketing Communications Marketing Communications provides means to send messages across markets or to a specific market. Its focus is on the products and services of the company and is mainly concerned with the increase in demand and proper positioning of the products and services (Marketing Communications). The tasks involved in Marketing Communications include promotion, advertising, publicity, branding and packaging among others. These tasks help in the efforts to increase product awareness and sales of the company's products and

The stock prices alone are already telling the investor which one is a better pick. It does not mean however, that CHL is a good investment or bad because the change is negligible. This means that the stock was not influence by market changes. The main reason may because of majority of the business is also ultimately dependent on the oil industry. Which is being an affected changes being in Middle East. The implications of portfolio return and risk in connection with market points out the degree of volatility in the changes of the portfolio return. In this case, a positive portfolio return with a positive return of the market both generates positive returns. The major defect of this analysis in the first place is the computation of returns within two day only. The extreme swings of the market are simply too unpredictable to make a safe investment (Graham 2004). To start with, it is not a profitable investment already. The picture we have painted above will change drastically should we look at this situation using 5 or 10 yrs as range when computing for stock returns. Obviously, the short term investing style is not as easy or profitable as when you are investing for the long term and evaluating major trends on the stock, not just the daily fluctuations on the stock market. In terms of predictability, we will find it extremely hard to judge the profitability of the stock alone just by using beta since it is also a relative value computed within a chosen time

Functions of Public Relations - Essay Example The two main functions of Public Relations are Organizational and Societal. The scope of Organizational Public Relations covers all the internal processes. This is the representation of the company in relation to specific groups or other organizations.

Societal functions of Public Relations on the other hand, deal with external processes or how the company reaches out to society. This includes activities or strategies directed towards the public with the intention of addressing their needs and interests.

Jamaican Music Industry - Essay Example Several researches were done on the Jamaican music industry between 2001 and 2002 and according to them Jamaican music industry is indeed significant to the national’s economy as it accounts for at least 12 percent of the total gross domestic product. The most amazing thing is the amount of the music export, which usually surpasses the local proceedings realized from the sale of music within Jamaica. In 2002, exported music amounted to 100 million dollars (McChesney, 2009, pp. 195). However, the current state of the Jamaican music industry is unable to sustain the artists due to inadequacy of professional and experienced producers, as well as unappealing distribution sector. The music quality fails to live up to the standards and piracy has risen to the extent that it has become a threat to the industry as it eats away the advantageous end of the industry. Moreover, the royalties from oversees music societies remain uncollected; there is lack of adequate knowledge when it come s to foreign markets and, thus, the amount of uncollected royalties from abroad is hard to define (McChesney, 2009, pp. 200). The purpose of this paper is to provide the information concerning the development of the Jamaican music industry and to access the main features within the industry. In addition to this, the paper will also bring forth the potential consequences with regard to the cultural industries within Jamaica. The main challenges on the way to achieving this aim are inability to get the full disclosure of the potential consequences in the area of cultural industries due to the diversified cultures entailed in Jamaica (Dorfma and Mattelart, 2005, pp. 43). Jamaican Music Development Jamaican Music industry has quite old and rich history but it became successful only in the early 1970s. This success is largely attributed to the late Bob Marley. As such, he has been acknowledged for transforming the reggae genre into an internationally known and accepted phenomenon. During this newly established wave of success, many new artists came up from Jamaica; the industry began its journey with regard to growth and development all over the world. Jamaican music can be said to have sprung from Jazz music, which was a stronghold of the U.S. Since Jamaica is a former U.S. colony, Jazz music was brought into Jamaica in 1949s and at that time Jazz was the only genre (Rutten, 2001, p. 302). This dominated the music industry until the late 1960s when another genre sprung from Jazz that was called race music but later renamed as Rhythm and Blues. Due to the emergence of this genre, jazz music slowly started its journey to oblivion in Jamaica. Indeed, Rhythm and Blues began transforming the music industry in Jamaica. Kingston began holding dances where strong sound systems would be installed and as such, music would dominate the air (Dorfma and Mattelart, 2005, pp. 47). Everybody, from young to old could be seen dancing to the tune of Rhythm and Blues. People would tr avel all the way to the U.S to obtain the new records and this became the trend. During dance sessions, a popular track would be played for up to twenty minutes in raw. The first sound systems to surface were Duke Reid and Clement Dodd. The competition between them became fierce as each wanted to outdo the other. This was ideal as it catalyzed the growth of the music industry in Jamaica. These systems exclusively played records from the U.S as at this time

Managerial research is different in such a way because it explores about the core elements that are needed to make prosper the business instead of searching such information that are not productive or result oriented. The managerial research is important because managers at all stages require timely and exact information for decision making. Whatever the decision making stage is, whether it is of tactical, operational or strategic level, the accurate information are required to for better decision making. At managerial level gathering of information is done through a sound and scientific research process. Each year organizations spend enormous amounts of money for research and development in order to mai ntain their competitive edge. Accurate information obtained through research leads to enormous benefits. In short, Managerial research is practical and finds its application in many places to identify the various characteristics and key factors responsible for the success of the firm and the products it develops. This research paper shows detailed and at length description of managerial research to describe that this type of research is different from other research methods. Definition of Research Research is the procedure of carefully studying and evaluating the situational elements surrounding an issue in order to search for solutions to it. A systematic thorough inquiry or inspection to find new information or correlations and to expand/verify current knowledge for some particular purpose. Why We Do Research?

As such, it is parallel to the social sciences in utilizing quantitative research and intersubjectivity as tools to apply measurement and critical analysis Historical Method The historical technique comprises the methods and strategies by which historians utilize historical sources and other proof to research and then to write history. There are different history rules generally utilized by historians in their work, under the headings of external criticism, internal criticism, and synthesis.

Consumer research decides customer loyalty, client satisfaction, and client preferences. In this way a managers job is different and difficult. Managers need some expertise to perform the responsibilities and activities related with being a manager. What kind of expertise does a manager require? Research by Robert L.

Technical skills contain information of and excellence in a certain specialized domain, for example engineering, computers, financial and managerial accounting, or production. These expertises are more significant at lower levels of administration since these supervisors are coping directly with workers doing the companyà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s work. Human skills engage the capability to work well with other individuals both separately and in a group. Because managers cope directly with individuals, this skill is essential! Managers with good human skills are capable to get the best out of their individuals. They recognize how to int eract, stimulate, lead, and inspire enthusiasm and confidence. These expertises are equally significant at all levels of administration. Eventually conceptual skills are the skills managers must have to consider and conceptualize about abstract and difficult situations.

Managerial Research Role in Decision Making At the beginning, it may be stated that business research or for that matter any research does not provide an exact answer to any issue but only help in making a good choice. Research is one of the four elements for making suitable and enduring decisions leading to interests of the business and ultimately its owners. A good place to begin is with some standard descriptions of decision making. Decision making is the research of recognizing and selecting options based on the values and priorities of the decision taker. Making a decision implies that there are substitute options to be measured, and in such a situation we want not only to recognize as several of these substitutes as feasible but to select the one that (1) has the utmost probability of achievement or success and (2) best fits with our objectives, desires, way of life, values, and so on. Decision making is the procedure of sufficiently decreasing insecurity and uncertainty about substitutes to permit a reasonable selection to be made from among them. This description stresses the information-collecting process of decision making. It should be eminent here that doubt is decreased rather than removed. Very few choices are made with exact certainty because total understanding about all the substitutes is seldom potential. Thus, every deci sion engages a certain amount of threat. If there is no doubt, you do not have a choice; you have an algorithma set of steps or a recipe that is pursued to bring about a set result. Managerial research for marketing is use for evaluating process, evaluating actual customer need, and for complete decision making. Decision making is quite difficult process and put the decision taker at a ground where he starts comparing hid decision options. The first problem he face is he wont be able to finalize the actual demand of result fir the decision has been taken. Managerial research helps identifying policy alternatives. Much work on knowledge exchange has concentrated on helping observers present their work into the decision-making procedure. Equally essential is the need for decision-making companies to be able of utilizing research in their decision-making. This ability engages a company having the capability to find the research proof it requires, judge its dependability, quality, significance, and applicability, adapt it into a possible format, and implement it. Problem solving and decision-making are important managerial expertise for business and life. Issue-resolving often engages decision-making and that is particularly essential for administration and management. There are procedures and methods to enhance decision-making and the quality of choices. Decision-making is more ordinary to certain traits, so these individuals should concentrate more on enhancing the quality of their choices. Individuals that are less normal decision-makers are often capable to make quality evaluations, but then require being more strong-minded in acting upon the evaluations made. Issue-resolving and decision-making are intimately connected, and each needs creativity in recognizing and developing choices, for which the brainstorming method is specifically helpful. SWOT analysis helps evaluate the power of a firm, a business proposal or idea; PEST analysis helps to evaluate the possible and appropriateness of a market. Good decision-making needs a mixture of e xpertise: creative progress and identification of choices, lucidity of judgment, determination of decision, and successful implementation. For group issue-resolving and decision-making, or when a harmony is needed, workshops support, within which you can include these tools and procedures as suitable. Here are some helpful techniques for successful decision-making and issue-resolving: First a simple step-by-step procedure for successful decision-making and issue-resolving.

Presidents And Affirmative Action :: essays research papers

Presidents and Affirmative Action In 1965, President Lyndon B. Johnson issued Executive Order #11246 at Howard University that required federal contractors to undertake affirmative action to increase the number of minorities that they employ. He wanted to ensure that minorities were recruited to have real opportunities to be hired and then eventually get a promotion. In 1969, the Department of Labor exposed widespread racial discrimination of the Construction Department so President Richard M. Nixon decided to encorporate a system of "goals and timetables" to evaluate federal construction companies according to affirmative action. This idea of "goals and timetables" provided guidelines for companies to follow and comply with affirmative action regulations. During the presidency of Gerald R. Ford, he extended affirmative action to people with disabilities (3) and Vietnam veterns (4) but there were no goals or timetables for these two groups. This type of affirmative action required recruitment efforts, accessability, accommodation and reviews of physical and mental job qualifications. President Jimmy Carter consolidated all federal agencies that were required by law to follow the affirmative action play into the Department of Labor. Before Carter did this, each agency handled affirmative action in its own individual way, some were not as consistant as other agencies were. He created the Office of Federal Contract Compliance Program (OFCCP) in 1978 to ensure compliance with the affirmative action policies. Affirmative action began to go downhill when Ronald Reagan and later George Bush came into office. Affirmative action lost some gains it had made and was mor or less ignored by the Republicans in the White House and in Congress. Affirmative action was silently being "killed" by our federal administrators. But among this destruction there was one positive aspect, the passage of Americans with Disabilities Act of 1990 (5). Finally to the Presidency of Bill Clinton. The Republicans are attempting to scare people into changing their party lines by misusing affirmative action. They are saying that affirmative action is nothing more than a quota (6) or reverse discrimination (7).
