We present a bilevel model for transmission expansion planning within a market environment, where producers and consumers trade freely electric energy through a pool. The target of the transmission planner, modeled through the upper-level problem, is to minimize network investment cost while facilitating energy trading. This upper-level problem is constrained by a collection of lower-level market clearing problems representing pool trading, and whose individual objective functions correspond to social welfare. Using the duality theory the proposed bilevel model is recast as a mixed-integer linear programming problem, which is solvable using branch-and-cut solvers. Detailed results from an illustrative example and a case study are presented and discussed. Finally, some relevant conclusions are drawn.

The Brazilian Ministry of Agriculture (MAPA) regulations establish 12 hours as the maximum pre-slaughter fasting period for broilers; however, many processing plants have considered this time is not sufficient, and consequently return the birds to the farms, with consequent economic losses and welfare problems. Therefore, it is necessary to investigate the possible effects of longer pre-slaughter fasting times. The objective of the present study was to evaluate the effect of pre-slaughter fasting times longer than those established by MAPA on broiler welfare, breast meat quality, and intestinal integrity. Forty 42-d-old broilers were submitted to different pre-slaughter fasting times: group I: 6 hours, group II 9h, group III 12h, and group IV 15h. Bird welfare was assessed before slaughter. After sacrifice, intestinal samples were collected to assess their morphology and morphometrics, and the Pectoralis major muscle was analyzed for pH and color. There was no influence (p>0.05) of treatments on breast muscle pH or color.There were no significant changes in intestinal morphometrics (p<0.05). Bird behavior was affected (p<0.05), suggesting that welfare was impaired as fasting time increased, but no differences in the analyzed parameters were detected between broilers fasted for 12 or 15 hours. It was concluded that the behavioral differences between birds fasted for 12 and 15 hours are not sufficient to assert that those fasted for 15 hours were in worse welfare conditions.

This research analyzes the origin of Welfare State, from the Report by William Beveridge. At the end of Second World War, the concern about citizenship rescue spread the idea of Social Welfare State. The British influence, also represented by the Beveridge Report, is of great importance in this process. Thus, analyzing the Beveridge Plan, which proposed a set of reforms within the social security system, along with its contributions to the emergence of British Welfare State, is crucial to a more complete historical parameter on the subject of the Protector State. The goal of this study is to clarify the influence of the Beveridge Report in the practical organization of the Welfare system in England

A Suécia está entre os países desenvolvidos que mais obtiveram êxito na construção do seu Estado de Bem-Estar Social (Welfare State). Esta instituição amadureceu durante os Anos Dourados do Capitalismo (1945 - 1975). O sucesso na sua construção pode estar ligado a uma série de fatores, como: o contexto internacional de Bretton Woods; as raízes históricas do país, com suas especificidades institucionais, econômicas e sociais; a atuação do Partido Social Democrata sueco, que contou com a participação de Gunnar Myrdal, um grande pensador econômico e um dos maiores teóricos referentes ao Welfare State; o Modelo Rehn-Meidner, que foi elaborado na década de 1950 e visou crescimento econômico, pleno emprego, controle inflacionário e equalização da renda simultaneamente através de políticas macroeconômicas contracionistas, Políticas Ativas no Mercado de Trabalho e Política de Salário Solidário. Dado tudo isto, o objetivo desta pesquisa é entender o processo de desenvolvimento do país e do seu Welfare State, analisando as medidas adotadas no período de 1950 a 1975, com particular interesse em identificar as possíveis influências que o Modelo Rehn-Meidner e o pensamento econômico e político de Gunnar Myrdal tiveram na escolha das políticas que contribuíram para o desenvolvimento do país. Além disso, será analisado o ambiente internacional da época, bem como a História da Suécia, com a finalidade de identificar se e como outros fatores contribuíram para o desenvolvimento socioeconômico da Suécia e do seu Estado de Bem-Estar Social
