Brazil boasts one of the world's most successful programmes to confront the HIV/AIDS epidemic, in spite of the country's rather low social and health indicators. The government recognised early the threat that HIV/AIDS posed to Brazil, and initiated a great number of programmes. However, the success of prevention programmes, assistance to those infected and control of the epidemic in Brazil are the result of a combination of political will, technical and human resource capacity, adequate funding and, most important, social mobilisation. 相似文献

Following the Fukushima disaster, several European countries revisited their policies and decided to phase out nuclear energy production. More recently, however, the EU taxonomy proposed a classification system of environmentally sustainable economic activities and consequently reopened the debate regarding nuclear energy. This study analyses public comments about the inclusion or exclusion of nuclear energy as a response to climate change, in the conceptual frameworks of ecological modernization, sustainability and technological neutrality. The study highlights the challenge of shaping energy policies amid dynamic circumstances and diverse viewpoints. Proponents of nuclear energy emphasised its low-carbon emissions and climate change mitigation potential, while opponents focused on issues of radioactive waste and environmental risks. The study reveals that sustainability emerges as a potential reconciling framework to match arguments to influence the EU's decision-making, while it reflects the political primacy of this process. Finally, this research recommends improving feedback visibility and enhancing clear communication, and suggests further research directions to understand future EU nuclear energy policies. 相似文献

Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Cameriere et al. studied the pulp/tooth area ratio by peri-apical X-ray images of the canines, to observe the apposition of secondary dentine. The present study examines the application of this technique in a Mexican identified sample coming from the Department of Physical Anthropology of the INAH, at Mexico City. The main aim of this work is to test the reliability of this method in a skeletal sample of a specific population, different from the samples used for its development. The obtained regression model explained 96.2% of total variance (R(2) = 0.962) with a standard error of estimate of 1.909 and a standard deviation of 1.947. These results demonstrate great reliability and that the age/secondary dentine relationship is not variable in this specific population. 相似文献

Government effectiveness could be explained by the level of well-informed electorate members, who use the press to learn more about politicians and public servants. Thus, a free press may improve citizens’ accessibility to this information, which in turn will make it more difficult for politicians and public servants to cover up or get away with corrupt behaviour, so the quality of the government could be affected by the media freedom. Accordingly, the main aim of this paper is to determine the effect of the freedom of the press on government effectiveness, considering additionally environmental, institutional, and political characteristics as factors that could determine the level of government effectiveness. To achieve this aim, we examined 202 central governments and compared them across countries using the World Bank data set of Governance Indicators for 2002–2008. The results show that the media, the organizational environment, and political characteristics may be determinants of the level of government effectiveness, taking countries’ economic development into account. 相似文献

This paper examines the psychological dynamics of the Group-Value Model for a behavioral orientation which has seldom been considered in the social justice literature: acceptance and support for change. A field study was conducted, with 176 participants members of an organization which was undergoing a change process. Participants were asked (a) to think of a specific relevant conflict situation with their supervisor; (b) to evaluate supervisor's behavior in that situation, with respect to relational and distributive justice; (c) to state the justice aspects most valued in conflict situations with their supervisor. A test of the model was conducted through a mediation analysis. According to the Group-Value Model (GVM), respect experienced within the group and pride in the group were mediating variables between justice judgements and orientation toward acceptance and support for change in the organization. Interactional and procedural aspects (relational judgements) were the only ones to predict pride, respect, and behavioral orientation, and were also the ones most valued in general conflict situations with the supervisor. The model was also tested at three different levels of analysis: organization as a whole, department, and work group. This confirmed pride and respect within the group as mediating variables between relational justice judgements and orientation toward acceptance and support for change at the department and workgroup levels. 相似文献
