In many parts of Australia the climate is such that people are working long hours in the heat. Consequences of excessive environmental heat stress range from reduction in safety due to impairment of concentration, to heat illness, which in extreme cases can be fatal. A critical factor in tolerance of workers to environmental heat stress is their level of hydration. Maximising productivity without compromising the health and safety of the work force requires quantification of the degree of stress posed by the thermal environment. For this purpose a number of heat stress indices have been developed. A recently introduced index is the Thermal Work Limit (TWL), which has been widely adopted and implemented in the underground mining industry in Australia. The field use of TWL and protocols in the mining industry with resultant reduction in heat illness and lost production is a practical endorsement of the index, and its validity under controlled conditions has been confirmed by a preliminary study. The further work needed to complete this validation forms part of this thesis. TWL was found to reliably predict the limiting workload in the controlled environment, reinforcing the validity of the algorithm and its application in the workplace. To date TWL has largely been used in the underground environment, however as the algorithm is equally applicable to the above ground environment where radiant heat forms a significant component of the thermal load, field studies were carried out at mining installations in the Pilbara region of Western Australia to evaluate this application of the index. The current industry standard index of heat stress is the Wet bulb Globe Temperature (WBGT). / The shortcomings of this index are widely acknowledged and in practice it is frequently ignored as it is seen to be unnecessarily conservative in many situations. The sensitivity of TWL to the cooling effect of air movement implied that TWL would be more relevant than WBGT as a predictor of the impact of environmental heat stress in outdoor work environments and this was supported by the results. On the strength of this, recommended management protocols linked to TWL similar to those already in place in many underground workplaces, were developed for the management of thermal risk in outdoor work environments. Maintaining adequate hydration is the single most important strategy to counteract the effects of thermal stress. No heat stress index can protect workers from the combined effects of dehydration and thermal stress. To document the hydration status of the outdoor workforce in the Pilbara, the hydration level of groups of workers was assessed from the specific gravity of their urine. To further evaluate whether the fluid replacement behaviour of the workers is adequate to replace fluids lost in sweat, a fluid balance study was carried out to quantify average fluid intakes and sweat fluid losses. The majority of workers were found to be inadequately hydrated at the start of the shift and their fluid intakes were in general well below the requirements to replace sweat losses - let alone improve hydration. Recommendations for fluid intakes based on documented rates of sweat loss are included in the thesis. Based on the findings of this study workable management strategies have been recommended to minimise the risk to outdoor workers in thermally stressful environments.

Estas cidades se destacam regionalmente pelos papéis intermediários que assumem na rede urbana paulista, bem como pela proeminência dos setores comerciais e de serviços. Contudo, também mostram indícios da negligência histórica do Estado no que se refere à oferta de serviços de utilidade pública de qualidade. As novas dinâmicas da economia brasileira, trazendo novíssimas demandas por produtividade e versatilidade por parte dos trabalhadores, torna imperiosa a melhoria da qualidade dos serviços de utilidade pública voltados à reprodução ampliada da força de trabalho e entre estes do transporte público coletivo. O transporte público coletivo por ônibus exige infraestruturas específicas e adaptação de infraestruturas de circulação para que a máxima eficiência das interações espaciais seja alcançada, devido ao conflito no espaço viário com os veículos privados... / This dissertation aims at discussing the public transportation in the cities of Bauru, Marília and Presidente Prudente in the State of São Paulo, from the analysis of concrete elements that interact on the creation of deep inequalities in access to the city, what damages the various categories of spatial interactions and, as a consequence, impairs the town itself as a general condition of production and general condition of social reproduction. These towns stand out regionally by the intermediary role that they assume in the urban network in São Paulo, as well as their prominence in the trade and service sectors. There is also evidence, however, of historical negligence of the state regarding the provision of high quality public services. The new dynamics of the Brazilian economy, bringing new demands for productivity and versatility of workers, makes it imperative to improve the quality of public services directed to the expanded reproduction of the workforce and, among these, the public transportation. The public transportation by bus requires specific infrastructure and the adaptation of movement infrastructure in order to guarantee that the highest efficiency of spatial interactions is achieved, given congestion of the road space by private vehicles...

A presente pesquisa tem por objetivo estudar a trajetória do Grupo de Osasco, grupo que reunia operários, estudantes e estudantes-operários. Para o desenvolvimento de nosso projeto utilizaremos fontes documentais provenientes de inquéritos policiais e material produzido pelas organizações revolucionárias (periódicos, manifestos, programas). Estes documentos são encontrados em arquivos como o Arquivo do Estado de São Paulo e o Centro de Documentação e Memória da UNESP (CEDEM). Também trabalharemos com História Oral, com base em depoimentos colhidos com personalidades que estiveram diretamente envolvidas com os eventos analisados em minha pesquisa. O recorte cronológico abrangerá o período que vai de 1966, início das atividades políticas do Grupo de Osasco, até 1971, quando praticamente todos os seus membros estavam exilados, presos ou mortos. Em setembro de 1971 tomba a última grande liderança remanescente de Osasco, José Campos Barreto, juntamente com Carlos Lamarca, no sertão da Bahia. Ao longo da segunda metade da década de sessenta, o Grupo de Osasco foi o principal movimento de esquerda nesta cidade. Em meados de 1968 dominava o movimento estudantil local, reunido em torno do CEO; dominava o sindicato dos metalúrgicos, e expandia sua influência a outras categorias através da criação de comissões de fábrica, mecanismo de representação que articulava os trabalhadores pela base, a margem do sindicato. Possuíam um vereador e vários representantes seus nas secretárias municipais. Pouco antes do AI-5, este grupo estava organizando associações de bairro sob sua influência, e nessas associações ministravam cursos de marxismo para populares. Coube ao Grupo de Osasco a organização da greve de julho de 1968, que se somou a onda de manifestações anti-ditadura que sacudiram o país. A repressão pós greve de julho jogou praticamente todos os militantes do Grupo de Osasco na clandestinidade, e estes acabaram por se integrar a VPR e partiram para a luta armada. / This research aims to study the trajectory of the Group of Osasco, group bringing together workers, students and student-workers. For development of our project will use documentary sources from of police investigations and material produced by organizations revolutionary (journals, manifestos, programs). These documents are found in archives and the Archive of State of São Paulo and the Documentation Center and Memorial of UNESP (CEDEM) . Also work with oral history, based on testimonies gathered with personalities who were directly involved in the events analyzed in my research. The outline will cover the chronological period from 1966, beginning of political activities of the Group of Osasco, until 1971, when virtually all of its members were exiled, imprisoned or killed. In September 1971 falls the last great remaining leadership of Osasco, Joseph Campos Barreto, along with Carlos Lamarca, in the interior of Bahia. Throughout second half of the sixties, the Group was the main Osasco leftist movement in this city. In mid-1968 dominated the movement local student, gathered around the CEO; dominated the union metallurgical, and expanded its influence to other categories by creating workplace committees, representation mechanism which articulated the workers at the base, the margin of the union. They had a city councilman and several their representatives in the municipal secretaries. Shortly before the AI-5, this group was organizing neighborhood associations under its influence, and these ministered associations for popular courses on Marxism. It fell to Group Osasco organizing the strike in July 1968, which added to the wave anti-dictatorship protests that rocked the country. The repression of post strike July played virtually every militant group in Osasco underground, and these will eventually join the VPR and went to battle armed.

It objectives to examine the contribution of medium level nursing students on scholarships at a teaching hospital s work force, at Natal/RN. It s a quantitative/qualitative, that uses descriptive statistics and analysis fulfilled with categories that emerged from research, through a dialog between the studied authors in the theoretical reference of nowadays work process, work force, non obligatory and remunerated traineeships, and night shifts. The collaborators of this research were 105 (73,43%) nursing technicians, medium level students on scholarships that fulfill remunerated traineeships at the hospital. The feminine gender was a major part of the collaborators, with 90 (85,70%), in which medium age was 29,71 years, 62 (59,00%) single, 57 (54,30%) don t have kids, 100 (95,23%) students on scholarships with complete medium level, 78,10% with professional experience before their insertion at the remunerated traineeships, 73 (69,50%) referred to enjoy the area, reason for the nursing technician course choice. About the technician course conclusion, 83 (79,00%) affirmed that happened between 2005 and 2008, and about traineeships time in the institution, 38 (36,20%) have between one and six months. About learning, 74 (70,50%) referred to learn with the nursing technicians and all fulfilled specialized courses, or grade up to bond with the school and be able to be trainees. These courses were considered low quality ones, what justifies the number of 54 (51,40%) students with scholarships that said their performance in studies is good and 75 (71,40%) are able to join it with the traineeships without problems. About remuneration as scholarship, 71 (67,60%) referred that helped to keep up with the studies, because this amount has specially this purpose, paying studies. About nonobligatory traineeships, the ABEn-RN affirmed that there s no following process to this traineeship mode, as long as there was never this concern, because obrigatory traineeships demand a lot of the efforts in the meetings. And COREN-RN doesn t supervise this way of contract. The present research observed that there is, in fact, a contribution of medium level nursing students on scholarships work force on the researched institution. Resigned to work circumstances established by the institution, representing the lack of human resources, materials, work conditions, and work insertion in night shifts, it s possible to affirm that the situation is irregular about the students on scholarships, besides the determinant risk factor to their lives and health. In addition to it, the students on scholarships, in order to maintain the quality of trainee in the institution, are obligated to fulfill courses to grade up, or specialized courses in nursing technician, at schools referred as bad quality ones / O presente estudo faz uma an?lise de est?gios n?o obrigat?rios e remunerados em enfermagem, como contribui??o para o processo de trabalho em sa?de e aprendizagem dos estudantes de cursos t?cnicos em enfermagem. Teve como objetivo examinar a contribui??o de bolsistas de n?vel m?dio de enfermagem na for?a de trabalho em um Hospital de Ensino em Natal/RN. Trata-se de uma investiga??o quantitativa/qualitativa, com uso de estat?stica descritiva e an?lise realizada a partir das categorias que emergiram da pesquisa atrav?s de um di?logo com os autores estudados no referencial te?rico do atual mundo do trabalho, for?a de trabalho, est?gio n?o obrigat?rio remunerado e trabalho em turnos e noturno. Os colaboradores desta pesquisa, foram 105 (73,43%) t?cnicos de enfermagem, bolsistas de n?vel m?dio que realizam est?gio remunerado no hospital. Houve predom?nio do sexo feminino com 90 (85,70%), com m?dia de idade de 29,71 anos, 62 (59,00%) solteiros, 57 (54,30%) n?o referiram ter filhos, 100 (95,23%) bolsistas com n?vel m?dio completo, 78,10% tiveram experi?ncia profissional antes de sua inser??o no est?gio remunerado, 73 (69,50%) referiram gostar da ?rea, motivo da escolha do curso t?cnico de enfermagem. Sobre a conclus?o do curso t?cnico, 83 (79,00%) afirmaram ter sido entre 2005 e 2008, e sobre o tempo de est?gio na institui??o, 38 (36,20%) t?m entre um e seis meses. Quanto ? aprendizagem, 74 (70,50%) referiram aprender com os t?cnicos de enfermagem e todos realizam cursos de especializa??o ou aperfei?oamento para ter o v?nculo com a escola e poder estagiar. Esses cursos foram tidos como de baixa qualidade, o que justifica os 54 (51,40%) bolsistas que disseram que o rendimento nos estudos ? bom e 75 (71,40%) conseguem conciliar com o est?gio sem problemas. Quanto ? remunera??o em forma de bolsa, 71 (67,60%) referiram que ajudavam a continuidade dos estudos, pois esse valor tem principalmente esse prop?sito de custear os estudos. Sobre o est?gio n?o obrigat?rio, a ABEn-RN afirmou que n?o existe uma rela??o de acompanhamento dessa modalidade de est?gio, posto que nunca houve essa preocupa??o, uma vez que os est?gios obrigat?rios tomam muito do esfor?o, nas reuni?es. E o COREN-RN n?o fiscaliza essa forma de contrato. Constatou-se na presente pesquisa que h? a contribui??o da for?a de trabalho de bolsistas de n?vel m?dio de enfermagem na institui??o pesquisada. Submetidos ?s circunst?ncias de trabalho estabelecidas pela institui??o, representando a car?ncia de recursos humanos, de materiais, de condi??es de trabalho, inser??o no trabalho em turnos e noturno, pode-se afirmar que esta situa??o ? irregular no contexto dos bolsistas, al?m de determinante fator de riscos para suas vidas e sa?de. Al?m disso, para que os bolsistas se mantenham na qualidade de estagi?rio na institui??o, s?o obrigados a realizar cursos de aperfei?oamento ou especializa??o de t?cnicos de enfermagem, em escolas referidas como de p?ssima qualidade

The hypothesis pursued is: to remunerate the productive capital inserted in the logic of the Flexible Accumulation Regime, the Sugarcane CAI of São Paulo state must raise productivity to extremely high levels, either by creating relative or absolute surplus value, forming conditions of hazardous work. To verify this hypothesis, we used two data collection methods: a) a qualitative one, with semi-structured interviews and field observations, and b) a quantitative one, through application of questionnaires to managers of the Human Resources Management of the sugarcane CAI, and data obtained from secondary databases of public agencies and private consulting companies. The results indicate that, with the mechanization of the sugarcane production, technological innovations were implemented to increase the productivity of all operations, which influenced the concrete work. In this process of productive modernization, there was a combination between predominant mechanized operations, and remaining manual activities, both with high productivity and hazardous working conditions. The manual activities became important to improve the quality of the production process, while the machines operation became central in the valorization of the capital in the CAI. This strategy imposes exploitation of labor at degrading levels, lowering wages, causing illness, and making workers extremely vulnerable to labor force control mechanisms. Payment based on production continues to play a central role among these mechanisms, but in a modern way with the inclusion of personal performance indicators, that is also the basis for selection and training strategies. The arduous working conditions is a characteristic of the Sugarcane Complex modernization process, because it is necessary to the productive capital valorization in this complex, reproducing the Flexible Accumulation contradictions in this complex. / Este estudo tem como objetivo responder a seguinte questão: por que as condições de trabalho penosas continuam a existir no processo de trabalho agrícola do Complexo Agroindustrial Canavieiro do Estado de São Paulo, mesmo com predominância de operações mecanizadas em todas etapas da produção? A hipótese que guia esta pesquisa é: para remunerar o capital produtivo inserido na lógica do Regime de Acumulação Flexível, o CAI Canavieiro paulista deve elevar a produtividade a níveis extremamente altos, seja pela criação de mais-valia relativa ou absoluta, formando condições penosas de trabalho. Para verificar esta hipótese utilizamos dois métodos de coleta de dados: a) qualitativo, com entrevistas semi-estruturadas e observações de campo, e b) quantitativo, pela aplicação de questionário a gerentes de Recursos Humanos de usinas do CAI Canavieiro paulista, além da análise de dados obtidos em bases secundárias de órgãos públicos e de consultorias privadas. Os resultados apontam que, com a mecanização do corte de cana, diversas inovações tecnológicas foram implementadas no processo de trabalho agrícola para elevar a produtividade desta operação, influenciando o trabalho concreto em todas as etapas do cultivo da cana-de-açúcar. Neste processo de modernização produtiva é formada uma combinação entre operações mecanizadas predominantes e atividades manuais remanescentes, ambas com elevada produtividade, que é obtida pela intensificação e extensão da jornada de trabalho. As atividades manuais passam a ter a função secundária de aperfeiçoar a qualidade do trabalho, sem serem eliminadas, enquanto a operação de máquinas se torna central na valorização do capital no complexo. Esta combinação é mais uma estratégia empresarial para aumentar a exploração do trabalho a níveis degradantes, rebaixando os salários, causando adoecimentos e tornando os trabalhadores mais vulneráveis às estratégias gerenciais de controle da força-de-trabalho. O pagamento por produção continua tendo papel central dentre estes mecanismos, mas sob uma forma moderna, cujo cálculo é baseado em indicadores de desempenho, método que também é base para a seleção e o treinamento. Neste sentido, a reprodução do trabalho penoso se configura como uma característica do processo de modernização no CAI Canavieiro paulista, pois é necessário à remuneração do capital produtivo neste complexo produtor de commodities.

Regardless of culture, socio-economic background, and quality of life, all students deserve the highest quality of education. But the reality is, many education systems around the world do not offer it. Investing in structural reforms in education has the potential to boost economic growth in countries around the world. By learning from different education systems strengths and weaknesses, policy decisions can be made that ensure students are given the opportunity for higher educational outcomes. This study analyzes high, middle, and low quality education systems around the world and the infrastructures that lead to educational success or failure. Fifteen education systems are chosen for this study which includes Shanghai-China, Singapore, Japan, Finland, Canada, Portugal, United States, Luxembourg, Spain, Hungry, Brazil, Argentina, Indonesia, Qatar, and Peru. Each system is analyzed in terms of its teacher quality, curriculum, school system structure, and educational equity. From this study, it appears that there is a high-correlation between four indicators and top- educational success. These four indicators include having a highly selective model for hiring teachers, recruiting teachers from a top-pool of graduates, having a high-level of prestige held for teachers in society, and insuring students of low socio-economic status are given equal educational opportunities for success. Recommendations for a new teacher training and selection model are discussed based on the top four indicators. These recommendations could cause educational gains for both the United States and other systems around the world.
