In sub-Saharan Africa, 72 per cent of urban and 98 per cent of rural households use fuelwood for energy. In Kenya use of charcoal in urban areas has risen by 64 per cent in two decades. Despite the charcoal industry providing employment to 500,000 people and generating over US$427 million that benefits grassroots communities, it has been kept out of the formal economies of this country. This review presents the status of the charcoal industry in Kenya, highlighting its contribution to livelihoods, production, utilisation, and implications for the environment; policy issues; and stakeholders' involvement. The review also proposes strategies to improve the sustainability of this sector.

La production de charbon de bois au Kenya et des stratégies pour l'augmentation de sa durabilité

Dans l'Afrique subsaharienne 72 pour cent de ménages urbains et 98 pour cent de ménages ruraux se servent du bois combustible pour leur propre énergie. Au Kenya l'usage de charbon de bois dans les secteurs urbains a augmenté par 64 pour cent au cours de deux décennies. Malgré le fait qu'elle fournit un emploi à 500,000 personnes et qu'elle génère plus de US$427 million de bénéfice aux collectivités populaires, l'industrie du charbon de bois reste écartée des économies formelles de ce pays. Cet examen présente la situation de l'industrie du charbon de bois au Kenya, en soulignant sa contribution aux moyens d'existence, à la production, et à l'utilisation ainsi que les implications pour l'environnement ; des questions concernant la politique ; et l'implication des parties prenantes. L'examen propose également des stratégies pour l'amélioration de la durabilité de cette industrie.

Producción de carbón y estrategias para aumentar su sostenibilidad en Kenia

En el África subsahariana, 72% de los hogares urbanos y 98% de los hogares rurales utilizan la leña como fuente de energía. En las áreas urbanas de Kenia, el uso de carbón ha aumentado 64% en dos décadas. A pesar de que la industria de carbón crea empleo para 500 mil personas, generando us$427 millones en beneficios para las comunidades de base, se la ha marginado de las economías formales de este país. El presente artículo examina la situación de la industria de carbón en Kenia, analizando, por un lado, su contribución a los medios de vida, y por otro, su forma de producción y su utilización, así como sus implicaciones para temas de política ambiental, además de la participación de los actores en la misma. Asimismo, el artículo propone estrategias para mejorar la sostenibilidad del sector.

Produção de carvão e estratégia para aumentar sua sustentabilidade no Quênia

Na África Subsaariana, 72 por cento de famílias da zona urbana e 98 por cento de famílias da zona rural utilizam lenha como fonte de energia. No Quênia,o uso de carvão nas áreas urbanas cresceu 64 por cento em duas décadas. Apesar da indústria de carvão proporcionar emprego a 500.000 pessoas e gerar mais de US$427 milhões que beneficiam comunidades de base, ela tem sido deixada de fora das economias formais deste país. Esta revisão apresenta o status da indústria de carvão no Quênia, destacando sua contribuição para os meios de subsistência, produção, utilização e implicações para o meio ambiente; questões de políticas e envolvimento dos stakeholders. A revisão também propõe estratégias para melhorar a sustentabilidade deste setor.  相似文献

Despite increased representation in correctional work settings, women still encounter obstacles in this male-dominated occupation—obstacles that have the potential to affect their levels of job stress and job satisfaction. Although gender-based differences in job stress and job satisfaction have been analyzed in several prison settings, much less work has been conducted in the often neglected correctional arena of jails. The current study fills this empirical void by examining jail staff at a large county correctional system in Orlando, Florida. Ordinary least squares regression analysis indicated that different facets of the work environment differentially affected the job stress and job satisfaction of 419 women and 493 men working in a large urban jail system. Specifically, role ambiguity, perceived dangerousness, coworker relations, input into decision making, and administrative support had larger effects on job stress for women compared to men. For job satisfaction, the only workplace variable to have a gendered effect was administrative support, which also had a greater effect for women than men. The findings reveal gender-related differences, especially in terms of job stress.  相似文献

The United States Government is placing increased emphasis on the development of financial measures, and measures of program effectiveness. The authors discuss government efforts in these areas. Various approaches and criteria are presented for the development of performance measurement systems, as well as generic criteria for selecting performance indicators, and obstacles to the process. Experience indicates that development of a performance measurement system is best served by a strategic planning approach with top management support, active management participation in goal setting, a small manageable number of goals, a strong link with the budget process, and an independent evaluation process.  相似文献

This was a five-year follow-up study of 572 male graduates of a boot camp in the South. The purpose was to determine what elements of life-course theory discriminated between four outcomes: (1) nonrecidivists, (2) recidivists with felonies, (3) technical parole violators, and (4) parole violators due to drugs. Findings indicated a relatively accurate classification of the first three outcomes.The discriminators between nonrecidivists and various types of recidivists in the study were indicators of informal social controls such as marriage, employment, children, and religiosity. Discriminators of felony recidivists were early sexual and physical abuse, gang membership, peer association, carrying a weapon, and early onset of crime. Discriminators associated with technical parole violation were attachment to female caregivers, self-esteem and self-efficacy, and perception that boot camp stimulated thinking about choices in life. The conceptual and policy implications of these findings are discussed in detail.  相似文献

Commentators differ on whether a diminished constitutional status for profit-driven speech is consistent with free speech theory. Most recently, the Supreme Court of the United States in Citizens United v. Federal Election Commission largely embraced an unfettered marketplace approach for political speech financed by corporate treasuries. Given the harm a free market approach is said to have produced in the economic realm, is this approach useful for structuring the constitutional protection economic expression receives? This article discusses the placement of economic expression within First Amendment theory and contends that restrictions on economic speech should be aimed at combating deceptive economic activities while overall regulatory goals should focus on requirements that enrich the supply of accurate and timely information.  相似文献
