At 6.4%, the unemployment rate for the Latin American and Caribbean region overall was the lowest for the past few decades, down from 6.7% in 2011. This is significant, in view of the difficult employment situation prevailing in other world regions. Labour market indicators improved despite modest growth of just 3.0% in the region’s economy. Even with sharply rising labour market participation, the number of urban unemployed fell by around 400,000, on the back of relatively strong job creation. Nevertheless, around 15 million are still jobless in the region. Other highlights of 2012 labour market performance were that the gender gaps in labour market participation, unemployment and employment narrowed, albeit slightly; formal employment increased; the hourly underemployment rate declined; and average wages rose. This rendering was obviously not homogenous across the region. Labour market indicators worsened again in the Caribbean countries, for example, reflecting the sluggish performance of their economies. The sustainability of recent labour market progress is also a cause for concern. Most of the new jobs in the region were created as part of a self-perpetuating cycle in which new jobs and higher real wages (and greater access to credit) have boosted household purchasing power and so pushed up domestic demand. Much of this demand is for non-tradable goods and services (and imports), which has stimulated expansion of the tertiary sector and hence its demand for labour, and many of the new jobs have therefore arisen in these sectors of the economy. This dynamic certainly has positive implications in terms of labour and distribution, but the concern is whether it is sustainable in a context of still relatively low investment (even after some recent gains) which is, moreover, not structured in a manner conducive to diversifying production. Doubt hangs over the future growth of production capacity in the region, given the enormous challenges facing the region in terms of innovation, education quality, infrastructure and productivity. As vigorous job creation has driven progress in reducing unemployment, attention has turned once again to the characteristics of that employment. Awareness exists in the region that economic growth is essential, but not in itself sufficient to generate more and better jobs. For some time, ILO has been drawing attention to the fact that it is not enough to create any sort of employment. The concept of decent work, as proposed by ILO, emphasized the need for quality jobs which enshrine respect for fundamental rights at work. The United Nations General Assembly endorsed this notion and incorporated it into the targets set in the framework of the Millennium Development Goals. This eighth issue of the ECLAC/ILO publication “The employment situation in Latin America and the Caribbean” examines how the concept of decent work has evolved in the region, progress in measuring it and the challenges involved in building a system of decent work indicators, 14 years after the concept was first proposed. Although the concept of decent work has been accompanied since the outset by the challenge of measurement, its first objective was to generate a discussion on the best achievable labour practices in each country. Accordingly, rather than defining a universal threshold of what could be considered decent work —regarding which developed countries might have almost reached the target before starting, while poor countries could be left hopelessly behind— ILO called upon the countries to define their own criteria and measurements for promoting decent work policies. As a result, there is no shared set of variables for measuring decent work applicable to all countries. The suggestion is, instead, that countries move forward with measuring decent work on the basis of their own priorities, using the information they have available now and in the future. However, this strategy of progressing according to the data available in each country tends to complicate statistical comparison between them. So, once the countries have developed their respective systems of decent work indicators, it will be also be important to work towards harmonizing them. ECLAC and ILO are available to provide technical support to this end. With respect to 2013, there is cautious optimism regarding the performance of the region’s labour markets. If projections of a slight uptick —to 3.5%— in the region’s economic growth in 2013 are borne out, labour indicators should continue to gradually improve. This will bring new increases in real wages and a slight drop of up to 0.2 percentage points in the region’s unemployment rate, reflecting a fresh rise in the regional employment rate and slower growth in labour market participation.

Esta pesquisa discute a autonomia da escola no Programa Dinheiro Direto na Escola - PDDE. Objetiva compreender qual concepção de autonomia orienta a referida política de gestão financeira da escola e quê implicações esta perspectiva aponta para a gestão da escola pública brasileira. Trata-se de um estudo documental, cujas fontes para a coleta de dados foram 35 documentos oficiais que normatizam o PDDE, compreendendo resoluções, medidas provisórias, informativos, cartilhas, manuais de orientação, entre outros documentos. Para subsidiar a análise, adotamos como referencial os estudos de Vitor Paro (1995); (2001); (2003); Licínio Lima (2000a); (2000b); (2001); (2002), Ângela Martins (2002), João Barroso (2003), entre outros, acerca da autonomia da escola. O estudo compreendeu dez anos de exercício do programa, que vai do ano de sua implantação (1995) ao ano de 2004. Os limites deste estudo situam-se na análise da autonomia da escola no plano das orientações. Portanto, não tem a pretensão de mostrar como a questão é vivenciada no interior da escola, a partir da ação concreta de seus atores. Trata-se apenas de uma análise conceptual da autonomia, a partir da análise dos documentos que regulamentam a política. Os resultados do estudo revelam que a concepção de autonomia que orienta o PDDE é uma autonomia funcional e operativa, e que aponta para três processos na gestão da escola pública brasileira: 1- para a re-centralização do poder do Estado no controle do emprego dos recursos financeiros da escola; 2- para a introdução da lógica mercantil na organização do trabalho na escola; e 3- para a desobrigação do Estado com o financiamento e com a prestação estatal de serviços nas unidades de ensino.

Esta dissertação trata dos impactos das reformas do Estado que vêm se delineando no Brasil, desde a década de 1990, sobre a formação do profissional da educação. Discute, ainda, a formação e profissionalização docente, no interior das políticas de reformulação da formação de professores, que, a partir de sua implementação, buscam veicular uma nova concepção de profissionalização, atribuindo aos professores novas exigências, imputando-lhes a responsabilidade pela melhoria da qualidade da educação, postulando uma nova concepção de profissionalização. Nesse contexto, a educação apresenta-se como uma política pública social que passa por reformas significativas, impondo mudanças substanciais aos cursos de formação de professores. A análise que aqui se realiza parte da premissa de que a formulação de políticas públicas educacionais sofre influência dos organismos internacionais, que se verifica nos princípios orientadores do projeto de modernização do Estado brasileiro. No entanto, dado as definições dessas políticas serem travadas no interior de embates sociais, surgem resistências por parte dos movimentos de educadores frente às imposições externas visando efetivas políticas de profissionalização docente. A fim de alcançar o objetivo de pesquisa proposto, buscou-se analisar as políticas de formação docente, verificando a concepção expressa pela retórica oficial acerca da profissionalização docente, a partir de um novo paradigma de formação de professores. Por meio da análise de documentos oficiais, pôde-se verificar que a concepção sobre profissionalização veiculada redefine conceitos e práticas, postulando que o novo paradigma de formação que deve ser partilhado por todos os educadores da educação básica. Tais medidas, além de visar atender uma grande demanda de professores, em virtude da expansão da escolaridade básica, objetiva desenvolver um novo perfil profissional que atenda às exigências produtivas e mercadológicas, decorrentes das mudanças no mundo do trabalho. Nessa perspectiva, esta dissertação está estruturada de modo a permitir uma abordagem do contexto em que se dá a implementação da Reforma do Estado brasileiro, a partir dos anos 1990, revisitando, posteriormente, a sociologia das profissões e os debates sobre profissão e profissionalização, verificando os diferentes enfoques que orientam as reformas na formação de professores. Por fim, analisa documentos oficias que consolidam, no Brasil, as reformas educacionais e difundem a profissionalização dos professores. Como resultados da investigação realizada, podemos destacar que: 1) as políticas de formação docente traduzem uma nova concepção de profissionalização e implementam a formação de novos perfis profissionais, em que o Estado utiliza mecanismos diversos para implementar a lógica de regulação e controle da profissão; 2) a repercussão nas condições salariais, carreira e de condições de trabalho, evidenciando a degradação de condições reais para um exercício profissional docente; 3) a grande insatisfação e resistência por parte dos movimentos de educadores, no que se refere à imposição dessas políticas, que assentados numa proposta contra-hegmônica, lutam em busca de uma política global de formação, que contemple a questão salarial e adequadas condições de trabalho, bem como o reconhecimento e a valorização da profissão, por meio de políticas garantidas e efetivadas pelos poderes públicos do Estado e profissionalização da docência.

Estuda a relação entre o Programa de Interiorização do Curso de Formação de Professores para Pré-Escolar e 1ª a 4ª do Ensino Fundamental, da Universidade do Estado do Pará e as políticas oficiais de formação de professores(as) desencadeadas no Brasil no período de 1999 a 2004. O objetivo é analisar a política de interiorização desenvolvida pela Universidade do Estado do Pará (UEPA) nesse Programa e sua relação com as políticas oficiais de formação de professores(as) implementadas no Brasil, a partir da década de 1990. A hipótese inicial era de que a política de formação de professores(as) adotada pela UEPA, no referido Programa, favoreceu a ampliação do mercado formativo no estado do Pará e, com isso, ocasionou uma corrida de professores(as) e de prefeituras àquela instituição, para a realização de processos de qualificação em nível superior. Para constatar essa hipótese, fez-se uma investigação do problema, orientada por pressupostos da abordagem qualitativa. Para coleta dos dados, realizou-se uma pesquisa bibliográfica, tendo como fonte: literatura especializada e documental; na pesquisa de campo, utilizou-se de entrevistas com os(as) alunos(as), professores(as), gestores(as) e os(as) secretários(as) de educação dos municípios atendidos pelo programa. Para análise dos dados, utilizou-se o critério de categorização temática para perceber e identificar as informações manifestadas nos enunciados dos conteúdos. A análise dos dados confirmou a relação do Programa de Interiorização do CFP com as políticas oficiais de formação de professores(as), especialmente, quando o Estado se desresponsabilizou dessa formação em nível superior, ao tornar a educação uma atividade não-exclusiva do Estado, o que favoreceu a ampliação do mercado formativo no Pará. A UEPA, sem apoio do Governo Estadual, oferta o Programa de Interiorização do CFP por meio de contrato de prestação de serviços educacionais.

This study quantifies fifth year medical students' knowledge after their participation in a basic clinical integration activity of psychiatry and pharmacology and investigates their opinions on the importance of the activity. A quali-quantitative study was performed using pre- and post-test assessment (multiple choice) and linguistic content analysis using the Discourse of the Collective Subject (DCS) technique. A significant increase in the percentage of correct answers in the post-test assessment was found compared to pre-test (p <0.001). The central ideas obtained from the DCS content analysis were: very relevant activity; expansion of the activity to other internships; difficulty in basic disciplines; application of cognitive assessment; and teacher's active participation in discussions. These results suggest that integration between pharmacology and the practical intern activities in psychiatry allowed pharmacological concepts to be broadened, rendering the learning meaningful. Although students identified the need for better organization of the activity, its the level of acceptance was verbalised through the suggestion that it could be extended to the other fifth year internships.

Environmental monitoring of aquatic systems is an important tool to support policy makers and environmental managers' decisions. Long-term, continuous collection of environmental data is fundamental to the understanding of an aquatic system. This paper aims to present the integrated system for environmental monitoring (SIMA), a long-term temporal series system with a web-based archive for limnological and meteorological data. The following environmental parameters are measured by SIMA: chlorophyll-a (µgL-1), water surface temperature (ºC), water column temperature by a thermistor string (ºC), turbidity (NTU), pH, dissolved oxygen concentration (mg L-1), electric conductivity (µS cm-1), wind speed (ms-1) and direction (º), relative humidity (%), shortwave radiation (Wm-2) and barometric pressure (hPa). The data were collected in a preprogrammed time interval (1 hour) and were transmitted by satellite in quasi-real time for any user within 2500 km of the acquisition point. So far, 11 hydroelectric reservoirs are being monitored with the SIMA buoy. Basic statistics (mean and standard deviation) and an example of the temporal series of some parameters were displayed at a database with web access. However, sensor and satellite problems occurred due to the high data acquisition frequency. Sensors problems occurred due to the environmental characteristics of each aquatic system. Water quality sensors rapidly degrade in acidic waters, rendering the collected data invalid. Data is also rendered invalid when sensors become infested with periphyton. Problems occur with the satellites' reception of system data when satellites pass over the buoy antenna. However, the data transfer at some inland locations was not completed due to the satellite constellation position. Nevertheless, the integrated system of water quality and meteorological parameters is an important tool in understanding the aquatic system dynamic. It can also be used to create hydrodynamics models of the aquatic system to allow for the study of meteorological implications to the water body.

Background: The use of all by-products of bovine slaughter is of high economic importance for the industries of products of animal origin. Among these products, fat has an important role, once fat rendering may generate several different products, such as protein material that may be used in the manufacture of meat products. However, in spite of the importance that the use of all by-products has for the economic balance of the industry, there are no reports on their use in Brazil, or studies that supply data on microbiological and physical-chemical local standards for this protein. Thus, the objective of this study was to evaluate microbiological and physical-chemical characteristics of protein material obtained from fat rendering, as well as to provide support for companies to use fat rendering to generate protein material, adding value to industrialized meat products.Materials, Methods & Results: The experimental production of edible protein obtained of fat rendering was conducted in slaughterhouse with supervision of the Brazilian Ministry of Agriculture, Livestock and Food Supply. Protein material was obtained in a continuous, humid heat system at high temperatures. Fat scraps containing protein were ground and cooked at high temperature (85 degrees C), and placed in a three phase decanter centrifuge. After centrifugation, protein material was ground again and packed. Samples were collected from 15 batches of protein material, and the following microbiological analyses were carried out: counts of aerobic mesophilic and psychrotrophic microorganisms, coliforms at 35 degrees C, Escherichia coli, sulfite-reducing Clostridium, and Staphylococcus aureus, besides presence or absence of Salmonella and Listeria monocytogens. The following physical-chemical analyses were also carried out: protein, total lipid, moisture, ash, carbohydrate, and energy content. Mean counts of mesophiles, psychrotrophs, and coliforms at 35 degrees C were 4.17; 3.69 and 1.87 (log CFU/g), respectively. Levels of protein, total lipids, moisture, ashes and carbohydrates were 27.50; 7.83; 63.88%; 0.24%; and 0.55%, respectively, and energy content was 182.63 kcal/100g.Discussion: Results of microbiological analyses demonstrated that, although low, the final product showed to be contaminated. Contamination that occurred during the second grinding procedure may be an explanation for these bacterial counts. Also, the temperature used for fat fusion was not enough to eliminate thermoduric microorganisms. However, even with the presence of indicator microorganisms in the samples, none was contaminated by E. coli, sulfite-reducing Clostridium, S. aureus, Salmonella or L. monocytogenes. Physical-chemical analyses showed that the product had adequate nutritional quality. Based on these results, it was possible to conclude that protein material obtained in fat rendering showed characteristics that enable the use of this product as raw material for processed meat products. Besides, the present study was the first one to present scientific results in relation to edible by-products obtained in fat rendering, supplying important information for slaughterhouses and meat-processing plants. The study also produced relevant data on the innocuousness of the product, which may be used to guide decision-making of health inspectors.
