Burnout is a growing concern in many areas of life. This manuscript first outlines the history occupational burnout. Research as it pertains to burnout in sport is then discussed, with an emphasis on broad conceptual models of burnout. The rationale for the current study is then given. First, previous research as shown that the longer one has been on the job the greater the likelihood of burnout (Pines & Maslach, 1978; Mor & Lalibaerte, 1984; Turnipseed, 1994). Therefore, Hypothesis I was that seniors were more likely to experience burnout than freshmen. Second, Smith (1986) and Coakley (1992) have maintained that athletes participating in coacting sports are more likely to experience burnout than those in interacting sports. Hypothesis 2 tested this assertion. Third, the role of emotional affect and burnout was examined. Hypothesis 3 stated that athletes with high positive affect are more likely to have lower burnout scores, while those with high negative affect are more likely to have higher burnout scores. The present study examined burnout in college athletes (N=216). The Eades Athlete Burnout Inventory was used to measure burnout. The Positive and Negative Affect Schedule was used to measure affect. Contrary to predictions, seniors reported lower burnout scores than any other year in school F (18, 580) = 1.67, p= .04. Also, there was no difference in burnout rates between coacting and interacting sports F (1, 213) = 1.96, p = .16. Finally, high positive affect scores were associated with low burnout scores E (1, 104) = 57.27, p <.001. Conversely, high negative affect scores were associated with high burnout scores F (1, 110) = 72.83, p < .001. The implications of these findings are also discussed. / Department of Counseling Psychology and Guidance Services

This thesis analyzed costs and benefits between the recruiting of active duty dentists and the proposed alternative of contracting them instead. Despite aggressive efforts to improve Dental Corps recruitment and retention, the annual loss rate has steadily increased. This has forced the Dental Corps into using alternative programs such as the Health Professions Scholarship Program (HPSP) and the Financial Assistance Program (FAP) in addition to the accession programs already being funded. Also, there are various recruiting costs along with the accession bonus that costs the Navy over $90,000 per dentist recruited. The scope of this thesis included, but was not be limited to: (1) a review of the current structure of pay for active duty Endodontists by referencing Additional Special Pay (ASP), Variable Special Pay (VSP), Dental Officer Multiyear Retention Bonus (DOMRB) and the Board Certification Pay (BCP) that dentists receive while serving on active duty (2) and a summary of private sector pay and incentives for dentists in private practice. The thesis also analyzed the differences between the two with a Cost-Benefit Analysis (CBA) model. The completed research found savings in cost for contracting already licensed and trained Endodontists in place of recruiting a general dentist and training them to become an Endodontist over the 10 year period as composed in the analysis. In addition, a steady-state model verified the CBA and showed savings in cost per year as well. Each model shows significant savings when contracting Endodontists in our shore based MTFs. Furthermore, to mitigate shortages, this research proposes to concentrate resources on military essential competencies and contracting workload for nonmilitary essential functions, such as Endodontists. Note that Endodontists were chosen because they are one of the larger nonessential specialties with billet inventories above the Operational Support Algorithm (OSA).

Decoherence due to photon scattering in an atom interferometer was studied as a function of laser frequency near an atomic resonance. The resulting decoherence (contrast-loss) spectra will be used to calibrate measurements of tune-out wavelengths that are made with the same apparatus. To support this goal, a theoretical model of decoherence spectroscopy is presented here along with experimental tests of this model.

ABSTRACT Looking up at the sky, we would never guess that our atmosphere contains between one and three billion tons of dust and other particles at any given time.1 Wind assists in keeping this dust airborne, but gravity wins most of the time, forcing the dust particles earthward, proving the old adage: “what goes up, must come down.” Precipitant dust levels in the Western Cape do not follow the same pattern as the precipitant dust levels in the summer rainfall areas of South Africa. Due to the very dry summer conditions in the Western Cape, the precipitant dust levels can be very high, especially if sources of fugitive dust are ignored. An environmental consulting company positioned precipitant dust monitoring units at strategic locations, taking process and open dust sources into account. Both wet and dry depositions have been reported on in this report as one figure. Seasonal changes in, and long-term trends of, the amount of precipitant dust were documented and statistically analysed to determine if the precipitantdust levels were above the South African legislated action levels. The particle size analysis performed on the precipitant dust indicated that the dust was predominantly less than 100_μm and that about 22 percent of the particles by volume were under 15_μm. No significant decline in the precipitant dust levels around the calcining industry was noted. Recommendations are that they increase the dust control measures on site, especially near to the DHF sampling location. There was a significant decrease in the precipitant dust levels to the north and south of the smelting industry from October 2001 to April 2005, p-value 0.005 and 0.048. The recommendations for the smelting industry are that they continue to eliminate fugitive dust sources and that they continue to maintain a high awareness of dust control.

A research report submitted to the School of Social Sciences, Faculty of Humanities of the University of the Witwatersrand in partial fulfilment of the requirements for the degree of Master of Arts in History 04 May 2015 / This report analyzes the reasons behind the adoption of out growing schemes (sistemas canavieiros) by two Mozambican sugar companies, namely the Companhia do Buzi and the Açucareira de Moçambique as well as the impacts of the companies’ decision on the mills as well as on local communities. Analyzing the adoption of out growing schemes is relevant due to the fact that the Companhia do Buzi and the Açucareira de Moçambique were the only two out of ten Mozambican sugar companies to collaborate with out growers. All the out growers were Portuguese citizens or ‘civilized’ Africans. The report also analyses the reasons and the impacts of the collapse of those schemes in the early post-colonial period. The report argues that the mills adopted out growing schemes to face the long term shortage and increasing costs of African agricultural labour. This strategy solved their problems but left the out growers indebted and frustrated and local communities dispossessed. On the collapse of the out growing schemes, the report argues that it resulted from the increasing lack of economic feasibility of sugar cane growing, which was a result of economic crisis and the authorities’ hostility towards the out growers.

Objetivo: Este estudo se propõe a verificar a influência do adesivo, material de preenchimento e hibridização da dentina na força de retenção de pinos intra-radiculares na técnica direta indireta e comparar o teste de tração de push out com o pull out. Métodos: 60 raízes de dentes bovinos com comprimento de 12 mm foram tratadas endodonticamente e divididas aleatoriamente em 6 grupos (n=10): grupo 1 (técnica direta-indireta, adesivo fotopolimerizável, cimento resinoso, teste de pull out); grupo 2 (idem ao grupo 1 porém o cimento resinoso foi substituído pela resina composta); grupo 3 (idem ao grupo anterior porém o adesivo fotopolimerizável foi substituído pelo químico); grupo 4 (idem ao anterior porém o teste utilizado foi o de push out); grupo 5 (idem ao grupo anterior porém o adesivo utilizado foi o auto condicionante); e grupo 6 (idem ao grupo anterior porém a dentina foi pré hibridizada). A força de retenção foi determinada através do teste de tração usando Universal Testing Machine (Instron). Todos os dados foram analisados usando one-way analysis of variance (ANOVA) com a significância de p<0.05 e complementadas com teste de Tukey. Após o teste, as interfaces adesivas onde ocorreram as falhas foram examinadas e classificadas. Resultado: Houve diferença estatística na comparação de materiais (adesivo, material de preenchimento). A hibridização da dentina não apresentou melhoras na retenção dos pinos . A maior parte das fraturas ocorreu na interface dentina/resina. Conclusão: Com base nos resultados obtidos, concluímos que material de preenchimento, o tipo de adesivo, influenciaram na retenção de pinos de fibra; e a pré-hibridização da dentina não apresentou melhoras a retenção dos pinos. O teste de push out apresentou mais detalhes para verificar o valor da adesão de cada terço da raiz; e o teste de pull out, para a força de retenção do pino ao longo do interior do conduto e o tipo de falha. / Objective: The aims of this study is to verify the influence of adhesive, filling material and dentin hybridization on fiber post retention force in diretc -indirect technique and compare the tensile test of push out with pull out. Methods: 60 bovine single roots with a length of 12 mm were endodontically treated and randomly divided into 6 groups (n = 10): group 1 (direct-indirect technique, light-curing adhesive, resin cement, pull out test), group 2 (same as group 1 but the resin cement was replaced by composite resin), group 3 (same as previous group but the light-curing adhesive was replaced by the chemical), group 4 (same as group 3 but the test was used was push out test), group 5 (same as group 4 but the adhesive used was the self etching) and Group 6 (same as previous group but the dentin was pre-hybridized). The retention force was determined by Universal Testing Machine (Instron). All data were analyzed using one-way analysis of variance (ANOVA) with significance of p <0.05 and complemented with Tukey test. After testing, the adhesive interfaces were examined and classifie. Result: There was a significant difference between comparison of materials (adhesive and filling material). The hybridization of dentin showed no improvement in the retention post. Most fractures occurred at the interface dentin / resin. Conclusion: Based on the results, we conclude that filling material, adhesive, influenced the retention of fiber posts, and the prehybridization of dentin did not improve the retention of fiber post. The push out test showed more details to verify the bonding between the post and dentin, and the pull out test for the retention force of the post inside the canal.

O presente trabalho teve como objetivo avaliar as correlações existentes entre as três diferentes formas de poupança (externa, privada e pública) para o caso brasileiro. Para isso, foram construídos alguns modelos econométricos, conforme estabelecido pela literatura internacional, com forma de auxiliar o diagnóstico aqui apresentado. Dentre as conclusões que foram extraídas deste trabalho destacaram-se considerações acerca da existência da Equivalência Ricardiana e do grau de substitutabilidade entre as poupanças externa e doméstica. Essas pontuações, entre outras, podem contribuir para a implementação de políticas públicas mais eficientes que visem a elevação da taxa de poupança da economia

Atheists are some of the least liked people in the world. Previous research has demonstrated that in most stigmatized groups, increased prevalence of the group increases prejudice towards the group. However, the opposite has been found with atheists- increased perceived prevalence decreases prejudice towards atheists. One post-hoc explanation provided for this difference is that since atheists are easily concealable and unorganized as a group, their greater prevalence may not be perceived as a threat. In the present thesis, I 1) attempted to replicate the existing finding that perceived increased prevalence would increase trust towards atheists and 2) directly tested the hypothesis that if atheist groups are presented as collectively powerful and coherent, increased prevalence will no longer decrease anti-atheist prejudice. I did not find support for the hypothesis that prevalence increases atheist trust, nor did I find support for my hypotheses that power and cohesion would manipulate distrust. Atheist prejudice is still pervasive, however, prejudice against atheists may be changing.
