Government Reforms in Brazil - Essay Example Again Brazil is not alone in this condition. Most countries in Latin and South America that were once ran by the military have abandoned this system in favor of democracy, the same way countries in Eastern Europe that were once part of the Communist Bloc are now embracing the democratic way of life as the better path to progress and peace. For these countries, there is greater pressure to institute these democratic reforms. The reform agenda enunciated by the Da Silva government in 2002 sought to tinker with the Constitution by amending its provisions on public administration, taxation, social security and ownership of energy and communications facilities. Da Silva's predecessor pushed these very same reforms but succeeded only in introducing new procedures in public administration. These reforms were also implemented on an ad hoc basis unaccompanied by meaningful structural changes. (Bresser-Pereira, L., 2003) Civil service reforms were placed high on the list because Brazil is known for its inefficient bureaucracy. Even progressive countries like UK and those in the OECD bloc are streamlining their bureaucracy in the increasing realization that structural inefficiencies in public administration are one of the main causes of the fiscal crisis and the budget deficit. (MARE-Brazil) The bureaucratic reforms pursued in Brazil were thus patterned after the UK model that is also popular in other OECD countries. Its main features call for the decentralization of government functions and services, providing more autonomy, more public accountability and separating policy formulation from execution. Part of the reforms was getting government out of business. This is the same policy carried out in UK, which has already privatized most public utilities. Brazil also turned over to non-government organizations the ownership and management of social and scientific activities. For example, 12 previously state-run hospitals in Sao Paulo are now in the hands of NGOs. (Bresser-Pereira, L., 1999) Another phase of the bureaucratic reforms serves to democratize entry to government employment by eliminating the policy that sets a single labor standard for civil servants. The government also put a cap on the salaries of employees in the judicial and legislative branches and adopted the total quality management approach to managerial activities in government service. (CLAD, 1998) Business and Tax Reforms Tax reform is high on the political agenda as part of the effort to encourage the informal business sector to go formal to increase the government's tax collection. The informal economy in Brazil is so large it is not limited to small and medium scale enterprises but extends to large concerns in the retail and construction industries. In the process, the government misses out on taxes that could run into billions of reals. To encourage the informal business sector to formalize their operations, the government uses the carrot and stick approach to persuade the companies concerned to register their businesses. It is emphasized that going formal gives these companies access to financing and technology assistance. (OECD,

Organizational Behavior - Essay Example My personality assessment results define me as being emotionally intelligent, and socially responsive. My emotional intelligence allows me to accurately understand and express emotions effectively. My social responsiveness makes me excel in interpersonal and social relationships. On combining these personality traits, I stand a chance of making a successful entrepreneur. Part II â€Å"Working with Others† Individuals with different personality traits gather up to make organizations. These individuals may be rooting from diverse social backgrounds. Someone’s social background determines most part of his personality. Therefore, I acknowledge the fact that in any given social setting, one meets people from diverse backgrounds who should work together as one community. This brings up the issue of working with others within the same social setting. My assessment sheet shows that I am good at communication (Edward, 2009 p.82). This entails both my speaking and listening skill s. I am a good public speaker as well as well as an attentive listener. On the aspect of leading others, I learned that many could trust me.

All these traits help me to predict my outcome when working with individuals from a diverse background. I have learned that I can build good professional relationships with my... From this research it is clear that organizational behavior comprises of other academic fields, which include psychology, management, sociology, anthropology, and communication. The interrelationship of these independent disciplines constitutes organizational behavior. As one of the elemental disciplines making up organizational behavior, psychology involves the scientific study of individuals’ minds by studying their mode of social conduct. Psychology aims at establishing an understanding of individuals within a social context. It entails the major concepts of human behavior like emotions, perception, personality, and interpersonal relationships. One can comprehend that this aspect of psychology gives organizational behavior its’ typical characteristics. It is psychology that brings about the study and application of knowledge on how individuals and groups act within any given social setting. Apart from understanding individuals, organization behavior also analyses the concept of leadership in organizations. It highlights the typical characteristics of ideal leaders based on their personality and behavior. Organizational Behavior achieves its objective of understanding individuals with self-assessment inventories. It is through these inventories that individuals get to know their psychological and sociological make-up. The biblical scripture asserts the importance of understanding ourselves as individuals before starting to understand other members of the society.

The Media and Its Responsibilities Essay Example | Topics and Well Written Essays - 3000 words

The Media and Its Responsibilities - Essay Example The media has continued to crusade for rights of the minority, better healthcare, improved education standards, environmental conservation in ways that seek to improve the welfare of communities and groups. To this extent, the media remains a formidable force for positive social transformation for the present and future generations. On the negative side, the media has incurred criticisms from groups, individuals, and sections of the society for practices considered generally unethical or harmful to consumers (Ward, 2011). Claims of explicit content reaching children and individuals with sensibilities continue to affect the positive aspects of the media. Moreover, there are increasing concerns of unethical professional practices among journalists and media houses with calls of increased regulation coming from religious organizations and other facets of the society’s leadership. It is important to consider the fact that some of the criminal activities in the society have been blamed on the loose regulations of the media content particularly with regard to uncensored exposure of pornographic materials and violent media content (Ward, 2011). The negative aspects of the media have tended to increase with the increasing regulation of the airwaves and the growth of the information communication and technology i nfrastructure across the globe. Philosophically, a comprehensive analysis of the media and its responsibilities could incorporate the theories of utilitarianism, virtue ethics and deontology. Both the positive and the negative aspects of the media could be assessed in terms of the ethical underpinnings on which the various actions are based. According to the theory of deontology, people should adhere to their obligations and duties, whenever they make decisions and judgments that have the nature of a moral dilemma (Shafer-Landau, 2012; White, 2009). According to this theory, the moral rightness or wrongness of an action

Facts of Palese v. Delaware State Lottery Office Essay

Facts of Palese v. Delaware State Lottery Office - Essay Example Palese contacted the Lottery Office in writing, describing his predicament and was directed to wait for one year so that his claim could be reviewed. 11 months later, Palese read in the dailies that the Lottery Office had transferred his unclaimed lottery jackpot to the State’s General Fund. Palese contacted the Lottery Office again and was told to explain how he had purchased the lottery and lost the tickets, much to Palese’s compliance. Even after hearing that Palese still had the play slip, the Lottery Office held that he was to be denied his claim since he could not produce his actual winning ticket. Palese took the matter to the court for litigation while the Lottery Office equally rushed to dismiss Palese’s claim on the account that Palese could not sufficiently state his claim for which the relief was to be granted. In the case Palese v. Delaware State Lottery Office, 1546-N, as the plaintiff, Palese accuses the Lottery Office of unjust enrichment since it had taken his rightfully owned prize to the State’s General Fund. In this light, he wants the prize he had won to be accorded him. Whether or not the rules of the Lottery Act such as Lottery Regulation 18 and 19 should be amended to allow the Lottery Act to capture unforeseeable circumstances such as inadvertent destruction or loss of the winning ticket. The Court of Chancery of Delaware heard from both the plaintiff and the respondent and referred to the directives in the Lottery Act, the Lottery Regulation 18 and 19 to arrive at its verdict.

Hollywood and Hip Hop Stereotypes Essay Example for Free

Hollywood and Hip Hop Stereotypes Essay For this activity, I choose this picture of American tennis champion Serena Williams. In the photo, Williams is wearing the latest attire for tennis which tends to reveal more skin as shown in her midriff-baring shirt for women players though it is meant to allow more freedom of movement and at the same time keep the player’s bodies from heating up during grueling matches. In this photo, it would appear Williams typifies the brute stereotype associated with African-Americans where those who are physically endowed, especially men, are savage, wild and violent and likely to be lustful (Ferris State University, 2010). Although this tag applies to men, this photo shows it could be applied to Serena though she has not declared herself a lesbian. Her physique is the result of her intense training regimen that comes with being an athlete in a sport that also requires strength. She can hardly be labeled as â€Å"Mammy† or even †Jezebel† where the former is laid-back and docile and the other is alluring but promiscuous. Her powerful strokes, her rippling muscles and nearly her athleticism makes her a â€Å"Brute† as all blacks are treated this way whenever they try are associated with sports. In conclusion, it would appear are blacks athletes or anyone physically endowed for that matter are classified brutes and along with that are the jokes or stereotyping. Racists believe this is the result of the evolution from apes to humans as the former are renowned to be the very aggressive and violent and the black people are said to have inherited these same animal traits which makes them faster, stronger, and more durable. Naturally, nobody in his right mind would think every black man is a dangerous animal waiting for the right moment to unleash his beastly qualities. If one were to judge a person it should not be on the basis of his ability, rather than the color of his skin and should not immediately subscribe to stereotypes despite the fact they do excel in sports. It is apt to frighten the womenfolk, prompting their fathers or husbands to protect them from these â€Å"savages† which of course, is wrong. Reference Ferris State University. (2010).

Effect of Zn Concentration on NiZnFe2O4 Nanoparticles

Effect of Zn Concentration on NiZnFe2O4 Nanoparticles CHAPTER-7 EFFECT OF Zn CONCENTRATION ON MAGNETIC AND DIELECTRIC PROPERTIES OF NiZnFe2O4 NANOPARTICLES 7.1 INTRODUCTION Ni (1-x) Zn (x) Fe2O4 (x=0.2, 0.4 and 0.6) nanoparticles are synthesized by using coprecipitation method. Zinc is a known metal, its role is important in the modification of ferrite properties by redistribution over the tetrahedral and octahedral sites of the spinel lattice. Rath et al (2002) reported the effect of zinc substitution on lattice parameter and magnetic properties on Mn-Zn ferrites prepared by hydrothermal precipitation method. Arulmurugan et al (2005) studied the effect of zinc substitution on Co-Zn and Mn-Zn ferrite nanoparticles prepared by coprecipitaion method. This chapter discusses the effect of zinc concentration on structural, magnetic and dielectric properties of NiZnFe2O4 nanoparticles prepared by co-precipitation method. The detailed experimental procedure involved in the preparation of NiZn ferrite nanoparticles has been already reported in chapter IV. In this method three different compositions such as x=0.2, x=0.4 and x=0.6 were used in the chemical formula Ni (1-x) Zn(x) Fe2O4 to analyze the properties of the ferrite nanoparticles. 7.2 RESULTS AND DISCUSSION 7.2.1 X-ray Diffraction (XRD) analysis The average crystallite size ‘t’ and the lattice parameter ‘a’ were calculated from X-ray diffraction data as reported in the chapter –IV. The values of particle size and Lattice parameter of all samples are also tabulated in Tables 7.1, 7.2 and 7.3. The particle size decreased from 24 to 12nm with the increase of Zn concentration. The same behavior of decrease in particle size with the increase of zinc concentration was also observed for the samples sintered at 600 °C and 900 °C. The decrease in particle size due to the increase of zinc concentration was 26 to 20nm for sintered sample at 600 °C and 31 to 25 nm for sintered sample at 900 °C respectively. This variation of particle size with zinc concentration at the above mentioned sintering temperature of Ni Zn ferrites nano particles is shown in Fig.7.1. The above observation shows that the presence of zinc blocks the grain growth. The surface temperature affects the molecular concentration at the surface of the crystal, and hence, the crystal growth (Upadhyay et at 2004). The formation of Zn-ferrite is more exothermic as compared with the formation of Ni-ferrite (Navrotsky Kleppa 1968). Thus, the crystal surface temperature increases with addition of zinc, decreasing the molecular concentration at the crystal surface and hence, obstructing the grain growth. The effects of zinc concentration on structural, magnetic and dielectric properties of Ni-Zn ferrite nano particles were studied. Particle size decreased with the increase of concentration. This decreasing in particle size behavior was observed for all the categories of concentration variation at different sintering temperature levels. The effect of zinc concentration on particle size showed a reverse effect compared with the effect of sintering temperature (chapter-IV), in which the particle sizes increased with the increase of sintering temperature. Table 7.1Particle size and Lattice parameter of as prepared Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles Table 7.2 Particle size and Lattice parameter of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 600 °C Table 7.3 Particle size and Lattice parameter of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 900 °C From Tables 7.1, 7.2 and 7.3 it is also observed that the lattice parameter increases with the increase of zinc concentration. The lattice parameter value for as prepared are increased from 8.33 to 8.37Ã… with the increase of zinc. For the samples sintered at 600 °C the lattice parameter value for lower zinc concentration (x=0.2) is 8.63Ã… and higher zinc concentration (x=0.6) is 8.66 Ã…. The similar behavior of increase in lattice parameter with zinc concentration is also observed as 8.64 to 8.68 Ã… in the samples sintered at 900 °C. This increase of lattice parameter with zinc concentration for all sintering temperatures of Ni Zn ferrites nano particles are also shown in Fig.7.2. The addition of Zn2+ in Ni-ferrite causes the Fe3+ ions to migrate from A site to B site. The larger ionic radius of zinc (0.82Ã…), compared with ferric ion (0.67 Ã…), makes the A site and thus the lattice expands, increasing the lattice parameter. A similar variation of particle size and lattice parameter with zinc content had been observed by Joshi Kulkarrni (1986) for Mg-Zn Ferrite. Fig.7.1Variation of particle size with zinc concentration for all sintering temperatures Fig.7.2Variation of lattice parameter with zinc concentration for all sintering temperature 7.2.2 Magnetic Properties The room temperature B-H hysteresis loops of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) sintered at 600 °C and 900 °C are shown in Figs.7.3 (a), 7.3 (b) and 7.3 (c). The variations of magnetic properties such as saturation magnetization (Ms), and coercivity (Hc) for different zinc concentrations (x = 0.2, 0.4 and 0.6) at particular sintering temperature were calculated from the hysteresis data and tabulated in Tables 7.4, 7.5 and 7.6. Table 7.4 Saturation magnetization and coercivity values of as prepared Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles Table 7.5 Saturation magnetization and coercivity values of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 600 °C Table 7.6 Saturation magnetization and coercivity values of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 900 °C The effect of zinc concentration on magnetic properties such as saturation magnetization and coercivity of all compositions of Ni Zn ferrite nano particles sintered at 600 °C and 900 °C are shown in Figs.7.4 and 7.5. The Fig.7.4 reveals that the saturation magnetization (Ms) decreases with the increase of zinc concentration. The saturation magnetization value decreased from 29.73 to 6.98 emu/g with the increase of zinc concentration for as prepared samples. The saturation magnetization value for the 600 °C sintered samples at lower zinc concentration (x=0.2) was 32.78 emu/g and higher zinc concentration (x=0.6) was 25.80 emu/g. A similar behavior of decrease in saturation magnetization with zinc concentration was also observed in the samples sintered at 900 °C as 64.34 to 39.50 emu/g. Fig.7.3 Hysteresis loops of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) (a) as prepared (b) 600 °C sintered (c) 900 °C sintered samples This decreasing of saturation magnetization with the increase of non magnetic Zn concentration is due to the interaction created by the zinc in the tetrahedral and octahedral sites. This shows the weakening of A-B interaction, whereas B-B interaction changes from ferromagnetic to antiferromagnetic state. The occurrence of minor decrease in saturation magnetization is also evidenced from the dielectric study, because it shows that there is a minor increase in dielectric constant. This reason leads to the conclusion that saturation magnetization variation with respect to concentration for 600 °C and 900 °C samples did not cause a rapid decrease in saturation magnetization like as prepared sample. Fig.7.5 shows that the coercivity values of NiZn ferrite nanoparticles decrease with the increase of zinc concentration. The coercivity values of as prepared nanoparticles decrease from 324.36 to 306.56 Gauss. Similarly the variation of coercivity values of nanocrystalline NiZn ferrite particles with increase of Zn concentration sintered at 600 °C and 900 °C are in the range of 347.31- 340.72 Gauss and 386.67-351.34 Gauss. This is due to the decreases of magneto crystalline anisotropy constant. The magneto crystalline anisotropy constant is negative for both Ni and Zn ferrites. The absolute value of magneto crystalline anisotropy constant larger for Ni ferrites than that of Zn ferrites (Verma et al 2000). The total anisotropy is equal to the sum of their individual anisotropy. So magneto crystalline anisotropy constant and hence coercivity decreases with the increase in Zn concentration. Also reasons behind the decrease in saturation magnetization and decrease in coercivity are c learly identified from the formation of smaller particle size even at the higher Zn concentration at all sintering temperatures. Fig.7.4 Variation of saturation magnetization with zinc concentration Fig.7.5 Variation of coercivity with zinc concentration 7.2.3 Dielectric properties The effect of zinc concentration on dielectric constant of all samples of Ni (1-x) Zn (x) Fe2 O4 nano particles are shown in Figs.7.6 (a), 7.6 (b) and 7.6 (c). The values of dielectric constant and dielectric loss are tabulated in Tables 7.7, 7.8 and 7.9. Fig.7.6 Dielectric constant curves of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) (a) as prepared (b) 600 °C sintered (c) 900 °C sintered samples Fig. 7.7 Dielectric loss curves of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) (a) as prepared (b) 600 °C sintered (c) 900 °C sintered samples The dielectric constant attained for zinc concentration x =0.6 led to a higher value for all the samples. The variations of dielectric constant with zinc concentration for all samples are also shown in Fig. 7.8. For all as prepared samples, the dielectric constant value increased from 10.92 to 25.08 with the increase of zinc concentration. The dielectric constant value for the samples sintered at 600 °C in lower zinc concentration (x=0.2) was 15.33 and it increased to 32.86 at higher zinc concentration (x=0.6). A similar behavior of increase in dielectric constant with increase in zinc concentration was also observed in the samples sintered at 900 °C as 19.37 to 48.18. Table 7.7 Dielectric constant and Dielectric loss values as prepared Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles Table 7.8 Dielectric constant and Dielectric loss values of  Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles  sintered at 600 °C Table 7.9 Dielectric constant and Dielectric loss values of  Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles  sintered at 900 °C Figs.7.7 (a), 7.7 (b) and 7.3 (c) show the effect on zinc concentration on dielectric loss factor of all samples of Ni (1-x) Zn (x) Fe2 O4 nano particles. The variation of dielectric loss factor value with zinc concentration for all sintering temperatures is also shown in Fig. 7.9. For all as prepared samples the dielectric loss factor value increased from 0.59 to 1.36 with the increase of zinc concentration. For the samples sintered at 600 °C the dielectric loss factor value for lower zinc concentration (x=0.2) was 0.68 and at higher zinc concentration (x=0.6) it was 1.61. A similar behavior of increase in dielectric loss with increase in zinc concentration was also observed in the samples sintered at 900 °C as 1.34 to 2.14. In Ni-Zn ferrites Zn occupies [A] site and Ni occupies [B]site, while Fe occupies both [A] and [B] sites. When Zn2+ is added in the place of Ni2+, with increase in Zn composition x, some of the Fe3+ ions get converted into Fe2+ ions. This increases the hopping between Fe3+ and Fe2+ ions, thereby decreasing the resistance of the grain. This increases the probability of electrons reaching the grain boundary. Hence the polarization and the dielectric constant increase. Fig.7.8 Variation of dielectric constant with zinc concentration Fig.7.9 Variation of dielectric loss with zinc concentration 7.3 CONCLUSION The effects of zinc concentration on structural, magnetic and dielectric properties of Ni-Zn ferrite nano particles were studied. The increase in zinc concentration obstructed the grain growth and decreased the particles size. The larger ionic radius of Zn, increased the lattice parameter values of NiZn ferrite nanoparticles with the increase of its concentration. The non magnetic property of zinc, decreased the saturation magnetization and coercivity values of NiZn ferrite nanoparticles. The dielectric constant and dielectric loss factor values also increased with the increase of zinc concentration due to the increase of probability of electrons reaching the grain boundary. Low value of particle size obtained at higher zinc concentration in the present work indicated that NiZn ferrite nano particles in lower nanometer scale could be obtained at higher zinc concentration.
