Research by the clinical operations and programs division Proposal

By the clinical operations and programs division - Research Proposal Example The range of the number of surveys that have been carried out is between almost 3500 to 4500 employees. This report aims at analysing the research and to gain a better perspective on the theories of performance related pay and its affects. One of the common factors those interest employees, employers and the government equally is the most essential element of employment - Pay. Pay affects the employers because it is an expense borne by the business and employee performance matters a lot to the business. Also this factor affects the employer's ability to recruit and retain labour force of quality. Employees are affected by pay as it is the only source of income it also sets the standard of living and measures a value for the performance and value of service. Lastly the government is affected by this since it directly affects the macro economic stability like employment, social economic development, inflation etc. There are a number of different basis on which pay to an individual is decided. One of the oldest forms of pay is Performance Related Pay this is discussed in detail in the next few parts. Performance Related Pay refers to pay scheme used to measure individual performance in the company (Monks, 1997). It can a lso be used to measure group or organisational performance. The main objectives of introduction of performance related pay were to increase motivation in employees to perform better, increase the self esteem of employees, provide better understanding of the job description and functions, create better communication amongst the participants, encourage employees to be self motivated, and help improve the institutional manpower planning. (Mohrman, Resnick-West & Lawler, 1989). Also performance related pay helps to contribute to overall performance and productivity, along with motivating employee to work better by linking the pay to the achievements of target rather than the length of service. It also helps recognise the achievements of individuals and identifies the under performers, thus creating fairness in pay (Monks, 1997). It was noted that performance related pay has proved to be useful for managerial staff since it allows them to be able to set goals that need to be achieved. Th is makes them motivated to work towards the goals as performance related pay ensures them of a reward on achievement of the goals. The principle of relating pay and performance has been very useful and has acted as a good motivator (Kessler, 1994). Linking of performance and pay is mainly based on Improved Motivation. Famous authors and researchers like Lawler, Porter, and Vroom have pioneered psychological theories of expectancy. The theory should a simple relationship between the efforts put in by an employee, the rewards, the motivation of the employee and the possibility of gaining if the required

Reaping the Whirlwind Essay Example for Free

Reaping the Whirlwind Essay Fighting human rights is a long and complicated process and â€Å"Reaping the Whirlwind† by Robert J. Norwell is a classical work, in which the author traces the development of human rights movement in one of the cities of American South Tuskegee, Alabama, specially concentrating on the rights of black-skinned community. The book gathers unique aspects of this region, as well as attempts to link them to national and global human rights development. Norwell is perhaps the best person to write such a book as he is a native of Alabama and holds a PhD degree on history. Norwell takes the reader from 1880-s to 1960-s, telling the story of Tuskegee Institute and it’s principal Booker T. Washington (1856-1915). Tuskegee appeared to be an outstanding example of human rights development. The local Afro-American community appeared to be educated and professional enough to promote their interests, including the ones in education, to overcome the position of conservative white officials. Norwell pays attention to both successes and disappointments of human rights movement in Tuskegee. The key idea of the book, is that in Tuskegee the black population managed to realize their own idea of harmony with the white Americans. In the later chapters Norwell concentrates on further development of the situation and describes how reality stepped away from accommodationalist views of Washington. Those ideas, which have been created in a small closed society were adapted by the rest and became essential for the whole nation. Human rights were won not only by legal and judicial means but also by persuasion, harsh disputes and even fighting opened violence. The book demonstrates how declared rights of African Americans gradually became factual and true. The first edition of the book ended in 1960, however in later editions Norwell updated the last chapter and briefly told of the latest development of human rights on the South from 1960-s until now. Norwell supposes, that Washington’s care of Afro-American activists created a base for human rights to flourish after World War II, because he managed to prepare enough leaders for the movement. Finally he concludes, that Washington should be more likely called a father of human rights movement than DuBois. In total the book is well written and quite easy to read. It is written for both those, who are interested in the subject and those, who require professional knowledge in the field of human rights development of the South. The book gives a picture of real struggles around human rights, which are often different from romantism of martin Luther.

Electrochemical Impedance Spectroscopy Study

Electrochemical Impedance Spectroscopy Study Electrochemical impedance spectroscopy An EIS study was carried out at different dc potentials in order to study the mechanism of ORR in O2 saturated alkaline solutions on prepared GDEs. The Nyquist plots of GDEs under different polarization potentials are shown in Fig. 5. The impedance diagrams show two different behaviors which depend on the applied dc potentials. In the other words, the shape of plots changed at different potentials, suggesting different electrochemical processes occurring on the electrode. The impedance spectra acquired at the potential lower than 0.7 V show one loop in the high frequency region associated with the time constant of a charge transfer process and semi-infinite diffusive manner related to Warburg component in the low frequency region. This semi-infinite diffusive character is related to the adsorption of reactants and intermediate products. The Nyquist plots of O2 reduction on GDEs at the E≠¥0.7 show two loops. The processes that could be involved on the electrode surface that would produce these changes include [37]: (1) Diffusion of O2 through the gas phase in the pores (of porous carbon supported catalyst) and the electrolyte to the reaction site. (2) Adsorption or heterogeneous surface reaction of the oxygen, together with oxygen diffusion. (3) Charge transfer. (4) Diffusion of reduction products into the bulk electrolyte Many reaction mechanisms have been proposed to describe ORR in aqueous electrolytes. Among these models, the Damjanovic model (Fig. 6) is one of the most extensively employed models, due to its applicability over a wide potential region. Damjanovic model describes the ORR as a multi-electron reaction which O2 molecules in the vicinity of the electrode are irreversibly reduced directly to H2O through 4-electron transfer (with a constant rate, k1) or to H2O2 through 2-electron transfer (constant rate, k2). The H2O2 formed can be reduced to H2O through 2-electron transfer (constant rate, k3) or diffuse into the bulk solution [38]. The ORR mechanism on transition metals has also been investigated by theoretical calculation based on the electronic structure [39-40]. The dissociative mechanism and the associative mechanism are proposed for a low current density range (more positive potentials) and a high current density range (more negative potentials), respectively [41]. Dissociative Mechanism (E≠¥0.7 V): In this mechanism, no H2O2 is produced. On a metal surface, O2 adsorption breaks the O-O bond and forms adsorbed atomic O, which further gains two electrons in the two consecutive steps, forming hydroxide ions. Since there is no adsorbed O2 on the catalyst surface, H2O2 cannot be formed. This mechanism can be considered a detailed form of the direct 4-electron pathway and can be written as follows: 1/2O2 + M(metal active sites) → O ºads (11) O ºads + e + H2O → OHads + OHaq (12) OHads + e → OHads → OHaq (13) Associative Mechanism (EË‚0.7 V): Since adsorbed O2 is present, the O-O bond may not be broken in the following steps, resulting in the formation of H2O2. The H2O2 could either be further reduced to H2O or be a final product. Therefore, the mechanism can be written as follows: O2,ads + 2H2O + 2e → H2O2 + 2OH (14) H2O2 + 2e → 2OH (15) The further reduction of H2O2(ads) to hydroxide ions occurs only once the enough overpotential has been reached and before the formed H2O2 diffuse into the bulk solution [41]. The two loop manner of GDEs in Nyquist plots may be related to two basic steps. On the other hand, for E ≠¥ 0.7 V, two time constants are detected during the impedance measurements (Fig. 5). The first time constant at high frequencies is associated with the charge transfer reaction according to Eq. 12, while the second may be associated with the further reduction of OHads to produce OH based Eq. 13. On the other hand, for EË‚0.7 V, the first time constant is related to H2O2 intermediate formation according to Eq. 14 and further semi-infinitive diffusive manner in the low frequency region can be explained by adsorption and diffusion of this intermediate into the bulk solution. In order to obtain quantitative information from impedance spectra in Fig. 5, two electric circuits were employed (Fig. 7). The electric circuit in Fig. 7a was used to simulate the impedance response of those spectra with OCP and E Using the equivalent circuits shown in Fig. 7, a constant phase element (CPE) is suggested instead of pure capacitance (C), due to the non-homogeneous surface of the electrodes. The impedance of CPE is defined as [Yo(jω)n]-1, where Yo is a constant with dimension (S.sn), while the exponent n denotes the correction factor pertaining to the roughness of the electrode and has values that range from 0 to 1. A pure capacitance yields n=1, a pure resistance yields n=0, while n=0.5 represents the ideal Warburg impedance. The true capacitance values can be calculated using the following equation [38]: C=[Yo Ãâ€" R (1-n)]1/n (14) According to equivalent circuits shown in Fig. 7, Rs is associated with the resistance of the solution, connectors, leads and wires. R1 is the charge transfer resistance of the reduction process from O2 to H2O2, R2 is the resistance of adsorbed species with H2O2 as the main intermediate or O2 adsorption into the GDE pores in the figure 7.a. The R1 and R2 circuit components in figure 7b are the charge transfer resistance of the reduction process of O ºads to OHads and the reduction process of OHads to OH, respectively. Parameters calculated from the equivalent circuits (Fig. 7) of O2 reduction on the GDEs are listed in Table 3. According to table 3, the Rs values change as a function of the potential, indicating that the contribution of the apparatus (connectors, leads and wires) from the total impedance of system shouldn’t be dismissed. So, the Rs values have a contribution function of both electrolyte and the apparatus resistance, i.e., connectors, leads and wires. R1 and R2 also show a dependence on the applied dc potentials (Fig. 8). By increasing the positive potential, the R1 values decrease. In the potential region of lower than 0.7 V, the adsorption of free O2 molecules happens on the metal catalyst and then O2,ads reduces to OHads (Eq.8). In the applied dc potential of E≠¥0.7 V, the adsorption of O ºads free radicals happens. By increasing the positive applied potentials, the adsorbed amount of O2,ads and O ºads increases and the further reduction process occurs more easily in the catalyst layer. So the R1 values will be decreased. The dependence of true capacitance values of the applied potentials is shown in Fig. 10. The adsorbed species enhancement by increasing the more positive potentials causes to decrease of C1 values. The R2 values for EË‚0.7 V are related to the adsorption of molecules like H2O2,ads into the GDE pores. When the potential is increased to more positive potentials, the adsorption of H2O2,ads spec ies by the oxygen atom orientation to the metal catalysts will be increased and R2 values became higher. In the potential region of E≠¥0.7 V, the OH,ads species which are reduced to OHaq, increase and charge transfer happens more easily. So the R2 values will be decreased. The C2 values also decrease because of more species adsorption (Fig. 10). Comparison of R values for GDEs shows that the Pt.Ru/C electrocatalyst has the lowest resistance in the whole range of applied dc potentials because of charge transferring occurring more easily and so ORR happens more rapidly at this electrocatalyst type. This behavior can be observed due to the synergistic effects of Pt and Ru catalyst species. The true capacitances of GDEs also show that the calculated of Pt.Ru/C and Ru/C electrocatalyst are higher than Pt.C ones. It is because the Ru species act as a protonic capacitor in the Pt.Ru/C and Ru/C GDEs. 3.5. Chronoamperometery The oxygen diffusion coefficients of GDEs were determined by chronoamperometry technique. Chronoamperograms were obtained by holding the potential of the electrodes at +1.2 V for 10 s and then holding it at +0.4 V relative to the Ag/AgCl electrode for 500 s with oxygen flowing along the electrolyte. With plotting i vs. t−1/2, the linear dependence relationship was obtained for different electrodes [42]: (16) Where I is the limited current, A the surface area of the electrode, D the diffusion coefficient, C the concentration of oxygen, n the number of electrons in the overall reaction of ORR, F the Faraday’s constant, t the time, and à ¯Ã‚ Ã‚ °Ãƒ ¯Ã¢â€š ¬Ã‚  is equal to 3.14. Fig. 11 shows the chronoamperograms of GDEs at +0.4V in relative to the Ag/AgCl in alkaline media. . Cottrell parameters are listed in Table 4, also. The results confirmed the higher Cottrell slope and D values for Pt.Ru/C electrode. So, the Pt.Ru/C cathode has more permeability and activity towards oxygen reduction reaction. Conclusion In this investigation, Pt/C, Ru/C and Pt.Ru/C bimetallic electrocatalysts were prepared by chemical reduction process. Then the resulted inks were coated on carbon paper and used as gas diffusion electrodes for oxygen reduction reaction in alkaline media. The surface structure of oxygen depolarized cathodes was studied by SEM and EDX analysis. The SEM results showed that all the cathodes consist of rough and porous structures. And Pt, Ru nanclusters were deposited quite uniformly onto/into Vulcan carbon supports with the average particle size of about 30-45 nm. The ORR activity of cathodes was evaluated in 0.1 M O2 saturated NaOH media. Comparison of cyclic voltamograms of Pt/C, Ru/C and Pt.Ru/C electrodes in O2 saturated solutions show that for Pt.Ru/C catalyst current increase induced by ORR is shifted towards more negative electrode potentials and only higher current values have been obtained within the ORR region. It can be concluded that the second metal addition has influenced the catalytic activity of electrocatalyst toward ORR. This matter can be related to synergistic effect, which is playing a critical role in ORR activity. The Pt.Ru/C cathodes showed lower Tafel slops and high current densities. An EIS study was carried out at different dc potentials in order to study the mechanism of ORR in O2 saturated alkalin e solutions on prepared GDEs. The Nyquist plots of GDEs under different polarization potentials show two different behaviors, suggesting different associative and dissociative electrochemical processes occurring on the electrode.

A Man For All Seasons Essays -- essays research papers

The 16th century was a time of political upheaval, a time of conflict and corruption †¦ and a time of heroes? All these elements are visibly present in Bolt’s book, A Man for All Seasons. As I was reading this story I was thinking that it could probably apply to our day and age but that begged the question. Why did Robert Bolt decide to use a 16th century character rather than a present time period character and setting? I believe that Bolt chose this man and his era because there things that he liked abut the man, there was no shortage of conflict and the he was worthy of being a hero. He fits into one of the archetype heroes. These three things I will touch upon in my seminar and I hope that my ideas will prove to be informative and enlightening.   Ã‚  Ã‚  Ã‚  Ã‚  One of the main reasons that Robert Bolt probably chose 16th century Thomas More as his hero for A Man for all Seasons was that he liked his personality. By that I mean that as Bolt wrote about More, he discovered more and more things that he found admirable about the man. At the outset, Robert Bolt was looking for a person who had a strong idea of who he is because this is what Bolt thinks is necessary to be a hero and this is exactly the type of man that Thomas More is. More saw in himself something that was his only and he was that it was something that allowed him to live life with confidence in himself. Only when he was denied that way of life was he able to accept his fate of death. Robert Bolt comments on this on page 13 of the preface. â€Å"†¦who nevertheless found something in himself without which life was valueless and when that was denied him, he was able to grasp his death.† This shows that Thomas knew that he had a sense of identity that no one else and he knew how important it was.   Ã‚  Ã‚  Ã‚  Ã‚  After Robert Bolt selected this man, he began to write and realised many more things about Thomas More, which had drawn him to the 16th century character. One of the things that Bolt found out was More’s sense of self. He remarks on this on page 12 of the preface. â€Å"At any rate, Thomas More, as I wrote about him, became for me a man with an adamantine sense of his own self.† Robert Bolt went back to this era long past because of that trait but it was as he wrote about him that he discovered just how strong his sense of identity was.   Ã‚  Ã‚  Ã‚  Ã‚  B... ...e me, Alice, that in silence is my safety under the law, but my silence must be absolute, it must extend to you.† (P56) He has found that so long he doesn’t give any indication to his opinion, hey cannot do anything to him legally. â€Å"MORE: There’ll be no trial, they have no case.† (P85) When he is asking his family to leave the country, he knows that he has protected himself to the best of his abilities. He should be safe except for the fact that he is dealing with a corrupt King who considers himself above the law.   Ã‚  Ã‚  Ã‚  Ã‚  Is there any way to do a play such as this in the 20th century? Evidently, Robert Bolt thought not and after analysing the story further, I have come to realise that he is right. The elements of the story, which were present in the 16th century, are not present in the 20th. There also may have been no one in this century that Robert Bolt liked enough and with the right characteristics. And of course, there is not enough conflict for one man to face as there was in that time. I believe that there are men (And women.) who would be able to face the problems that Thomas More had to face but we can all be thankful that there is no need for it.

A Raisin in the Sun and Brown versus Board of Education :: Race Racial Segregation Lorraine Hansberry

The American Dream Langston Hughes wrote a poem, in 1951, called â€Å"Harlem†. It sums up the play A Raisin in the Sun, by Lorraine Hansberry: â€Å"What happens to a dream deferred? Does it dry up like a raisin in the sun? Or fester like a sore- and the run? Does it stink like rotten meat? Or crust and sugar over- like a syrupy sweet? Maybe it just sags like a heavy load. Or does it explode?† Lorraine Hansberry uses this poem to open A Raisin in the Sun. This dialogue suggests what happens to the African American’s dream during the Brown v. Board of Education trials. While critiquing this play I was a little disappointed that Brown v. Board of Education was not discussed directly. However, I did find the plot of the play, and the people who were attending it to be very interesting. The plot of A Raisin in the Sun does not directly talk about the Brown v. Board of Education decision. Actually, very little of the play, until the end, deals with any kind of racial segregation. The play revolves around four main characters; Walter, a defiant husband who desperately wants to become rich; Ruth, Walter’s devoted wife; Beneatha, Walters intellectual younger sister, who is much better educated than the others and wants to become a doctor; and Mama, the head of the household, and also Walter and Beneatha’s mother. Mama inherits some money from her dead husbands insurance. With this money she buys a house in an all white community, and gives the rest to Walter. He is instructed to put some money away for Beneatha’s medical school, and the rest into a checking account for himself. Walter, however, desperate to become rich foolishly gives the money to his friend to invest in a liquor store. His so called friend runs off with all of the money Walter gave him. In order to get some money back for Beneatha to go to school, Walter wants to sell the house back to the white community. The community offered the Younger family a lot of money for the house, because they did not want Negroes living next to them. In the end however, Walter, realizes that it is this house that unifies the family and is what truly will make them happy, instead of being rich.

Duty of care Essay

1.1 â€Å"Duty of care† means to provide care and support to individuals within the law and also within the policies, procedures and agreed ways to work. It is about keeping the service users independence, to support and enable them to live within an environment free from prejudice and safe from abuse. Everyone is entitled to their own opinions, choices and we should respect that at all times while promoting them as an individual. 1.2 By working within standards set out and within our own capacity we will prevent harm from occurring to ourselves, others and the individual. By giving an individual choice and respecting their views/wishes they know that their independence has not been taken from them, giving them more confidence if an issue of safeguarding etc. were to arise. To understand and be able to pass on the procedures in place if we are suspicious or aware of abuse, an individual being endangered or poor work practice by another carer or agency. Reporting, recording are the steps needed to ensure that any form of safeguarding or protection issues are dealt with immediately and correctly. 2.1 While working in care, the aim is to give the best possible standard of care to service users, but sometimes there can be a conflict beetween the individual’s or their family’s wishes and rights and the duty of care. In this case the most important thing is to decide whether the person is aware of the risks and consequences of the decision and has the capacity to make the decision. Before taking best interest decisions I have to make sure that the person definitely lacks the capacity. The person or their next of kin has an overall right and responsibility in decision making for issues relating their care, and I need their consent to deal with certain issues. When a dilemma arises, my responsibility is to support individuals or their families to make informed choices. Even if I disagree with their decision, I can only give advice but can not force them.
