Organizations are faced with increasing pressure to engage in sustainable development and to integrate environmental and social dimensions into their traditional performance metrics. Prior research suggests that lean management and supply management are potentially important determinants of environmental performance and can be seen as capabilities that ease the adoption of environmental practices. To help understand the roles of lean and supply management in regards to improving the firm's environmental performance, a conceptual model proposes that the magnitude of environmental practices mediates the relationship between lean and supply management with environmental performance. To test the model, plant-level survey data from a sample of Canadian manufacturing plants is used. The results indicate that supply management and lean activities provide means by which resources are invested in environmental practices. The empirical analysis also confirms that the impact of lean management, and to a lesser extent supply management, on environmental performance is mediated by environmental practices. © 2012 Elsevier Ltd.

This article aims to analyze the HIV/AIDS policies, particularly campaigns, in the perspective of race and gender intersection. Such perspective enables the understanding of how gender oppression and race oppression intersect each other, whereas, on the other hand, political action deconstructs these inequalities and enables the transformation of institutions in the promotion of gender and race equality. The ethnographic data I analyzed were collected during a qualitative research that focused on the actions carried out by organizations of the black movement and on their demands before the public power for participation in the struggle against the spread of the epidemics among the black population of the Southern region of Brazil. In the first part, I employ the concept of biopower to analyze the relation between race, gender and health. In the second part, I analyze the representations of body and subject activated in two nationwide HIV/AIDS campaigns centered on the image of a black woman, and the debates they brought about. The analysis reveals the centrality of the body as the expression of the black women movement's political struggle, stressing on and questioning the social vulnerability that results from the impact of biopolitics on the bodies, especially when gender and race are brought together.

This qualitative study aimed at learning the masculine conception of paternity and understanding the masculine strategies to cope the legal, social and affective pressures of this process. The collection of information was done through semi-structured interview with eight adolescents from Porto Alegre - RS, Brasil, ranging between 15 and 19 years old, who experienced paternity. The interpretation and analysis were based on the content analysis. From the analysis of these youngsters' reports the following categories have emerged: Adolescents Relationship; Paternity and Gender; and, Meaning of Being a Father. The attentive look to paternity in adolescence brings to light the comprehension of issues regarding the masculine exclusion in objective life experiences marked by the commitment with paternity.

A new dimensionless correlation for the Nusselt number and high Prandtl number is presented. It can be used to correct the temperature profiles obtained through a global method. The mathematical model is transient two-dimensional, assuming laminar flow. Thermal losses are considered for all tank walls. Several cooling cases are simulated varying the aspect ratio, the cooling rate and the volume of the tank. The temperature fields are used to obtain the internal coefficient of heat transfer. It was use the Buckingham theorem to determine the dimensionless groups that represent the cooling process. The correlation is checked with numerical simulations results with good agreement. © 2012 Elsevier Ltd. All rights reserved.

Index species useful for correlations with the International Stratigraphical Column are rare or absent in the Pennsylvanian-Permian strata of the Paraná Basin in Brazil, preventing accuracy in geochronologic assignments. Besides, absolute datings are very scarce in comparison with other Gondwana basins. This paper presents palynological data from an outcrop on the surroundings of the Candiota coal mine, southmost Brazil, from several levels of the Rio Bonito and Palermo formations. The presence of certain index species of spore-pollen allowed the recognition of two Permian palynozones: the Vittatina costabilis and the Lueckisporites virkkiae zones. Furthermore, U-Pb in zircons from a volcaniclastic level interbedded in the coal strata of the former unit was analyzed through LA-MC-ICP-MS method, providing a new absolute age dating of 281.4 ± 3.4. Ma (Cisuralian, Early Permian). This dating is assumed as the oldest occurrence of the L. virkkiae Zone in Paraná Basin, which contains index species that are widespread in other Gondwana basins. A well distributed surface boundary occurs in this section also, allowing local and regional correlations. These new biostratigraphical and geochronological data are integrated, in order to offer a deep analysis on the stratigraphical significance for correlations across the Occidental Gondwana. © 2011 International Association for Gondwana Research.
