The generation growing and diversified of Municipal Solid Waste is configured as an environmental problem, economic and social deterioration, especially, by application of inappropriate management of them. Faced with this urban context, the research in development presents as specific objective assessment of the quality of life of the gatherers of recyclable materials were active in the city of Juiz de Fora, in the brazilian state of Minas Gerais. In addition, the objective is, still, the recognition of the activity of sorting performed by "scavengers" in order to maximize the reduction, reuse and recycling energy and material waste daily. The proposed methodology is based on the application of the questionnaire Word Health Organization Quality of Life (WHOQOL-100), prepared by the World Health Organization, in order to value the quality of life of the gatherers of recyclable materials, involved, even in educational workshops in order to discuss and organize strategies of health care and scouting to the basement to public policies. 相似文献

Radiological nuclear emergency responders must be able to coordinate evacuation and relief efforts following the release of radioactive material into populated areas. In order to respond quickly and effectively to a nuclear emergency, high-level coordination is needed between a number of large, independent organizations, including police, military, hazmat, and transportation authorities. Given the complexity, scale, time-pressure, and potential negative consequences inherent in radiological emergency responses, tracking and communicating information that will assist decision makers during a crisis is crucial. The emergency response team at the Angra dos Reis nuclear power facility, located outside of Rio de Janeiro, Brazil, presently conducts emergency response simulations once every two years to prepare organizational leaders for real-life emergency situations. However, current exercises are conducted without the aid of electronic or software tools, resulting in possible cognitive overload and delays in decision-making. This paper describes the development of a decision support system employing systems methodologies, including cognitive task analysis and human-machine interface design. The decision support system can aid the coordination team by automating cognitive functions and improving information sharing. A prototype of the design will be evaluated by plant officials in Brazil and incorporated to a future trial run of a response simulation. 相似文献

Female sex workers (FSWs) experience elevated risk for HIV and sexually transmitted infections (STIs) through unprotected sex with male clients, yet the complexity of these commercial relationships remains understudied. From 2010 to 2011, we explored FSWs' conceptualizations of various client types and related risk behavior patterns using semistructured interviews with 46 FSWs in Tijuana and Ciudad Juarez, Mexico, where FSWs' HIV/STI prevalence is increasing. Our grounded theory analysis identified four types of commercial relationships: nonregular clients, regular clients and friends, clients who “fell in love” with FSWs, and long-term financial providers who often originated from the United States. As commercial relationships developed, clients' social and emotional connections to FSWs increased, rendering condom negotiation and maintaining professional boundaries more difficult. Drug abuse and poverty also influenced behaviors, particularly in Ciudad Juárez, where lucrative U.S. clients were increasingly scarce. While struggling to cultivate dependable relationships in a setting marked by historical sex tourism from a wealthier country, some FSWs ceased negotiating condom use. We discuss the need for HIV/STI research and prevention interventions to recognize the complexity within FSWs' commercial relationships and how behaviors (e.g., condom use) evolve as relationships develop through processes that are influenced by local sociopolitical contexts and binational income inequality. 相似文献

We study the dividend policy of firms in regulated network industries, focusing on the impact of different regulatory regimes and government control. We link payout and smoothing decisions to different regulatory mechanisms (cost‐based vs. incentive regulation) and state versus private ownership. We test our predictions on a panel of listed European electric utilities, accounting for potential endogeneity of the choice of regulatory and ownership patterns. We find that incentive‐regulated firms smooth their dividends less than cost‐based regulated firms and that they report higher target payout ratios. Consistent with the interest group theory of regulation, we find that incentive regulation schemes are less likely when the state is still an important shareholder in the sector. Additionally, our results show that government control undermines the efficiency‐enhancing effects of incentive regulation on dividend policy, for example, lower smoothing is only due to private firms.

On Decomposing Net Final Values: Eva,Sva and Shadow Project 总被引:1,自引:0,他引:1
A decomposition model of Net Final Values (NFV), named Systemic Value Added (SVA), is proposed for decision-making purposes, based on a systemic approach introduced in Magni [Magni, C. A. (2003), Bulletin of Economic Research 55(2), 149–176; Magni, C. A. (2004) Economic Modelling 21, 595–617]. The model translates the notion of excess profit giving formal expression to a counterfactual alternative available
to the decision maker. Relations with other decomposition models are studied, among which Stewart’s [Stewart, G.B. (1991),
The Quest for Value: The EVA™ Management Guide, Harper Collins, Publishers Inc]. The index here introduced differs from Stewart’s Economic Value Added (EVA) in that it
rests on a different interpretation of the notion of excess profit and is formally connected with the EVA model by means of
a shadow project. The SVA is formally and conceptually threefold, in that it is economic, financial, accounting-flavoured. Some results
are offered, providing sufficient and necessary conditions for decomposing NFV. Relations between a project’s SVA and its
shadow project’s EVA are shown, all results of Pressacco and Stucchi [Pressacco, F. and Stucchi, P. (1997), Rivista di Matematica per le Scienze Economiche e Sociali 20, 165–185] are proved by making use of the systemic approach and the shadow counterparts of those results are also shown. 相似文献

This research explores the incidence of individual and contextual factors on the entrepreneurial intention of engineering students, as they are called to be the founders of new technology-based firms, which are required for the generation of economic growth and employment. A quantitative study comprising 1,004 engineering and architecture students has been conducted, in which both contextual factors (perception of economic-administrative barriers and unemployment rates) and antecedents of entrepreneurial intention from Ajzen’s Theory of Planned Behaviour have been examined. Results show that individuals with a high entrepreneurial intention show a favourable attitude towards the behaviour and see themselves capable of undertaking an entrepreneurial behaviour. Perception of social support, although strong, is not such a relevant factor. Regarding contextual factors, these do not discourage individuals with high entrepreneurial intention. Last, the role played by unemployment rates is unclear. Consequently, technical universities and governments, in their social responsibility to foster entrepreneurship in future young professionals, should take these factors into account to promote an encouraging climate for the development of an entrepreneurial spirit. 相似文献

Abstract The effects of a primary prevention social norm intervention on binge drinking among 1st-year residential college students were examined. Six hundred thirty-four students attending a medium-sized public university in the South were randomly assigned to receive a two-phase social norm intervention or the standard campus psychoeducational prevention program. At posttest, no differences were found between intervention and control group students on any of the alcohol use and alcohol-use risk factor measures. Significant subgroup differences were found by stage of initiating binge drinking behaviors, for frequency of alcohol use, F(3, 507) = 3.69, p = .01; quantity of alcohol use, F(3, 507) = 2.51, p = .05; and social norms, F(3, 505) = 2.53, p = .05. These findings suggest the need for tailoring social norm binge drinking interventions to students' stage of initiating heavy drinking and carefully monitoring for potential negative, as well as positive, effects of norm-based prevention messages. 相似文献
