The forensic value of Y-STR markers in Guiné-Bissau was accessed by typing of 215 males. Allele and haplotype frequencies, determined for loci DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439 and the duplicated locus DYS385, are within the limits of variation found in other populations south of the Sahara. The level of discrimination achieved is Guineans is higher than for European or other African populations with comparable data. The haplotype diversity of 0.9995 is reduced to 0.9981 when the minimal haplotype is considered thus revealing the importance of increasing the number of typed loci.  相似文献

This article explores the links between biodiversity and sustainable human development, on the one hand, and the globally agreed Millennium Development Goals. In particular, it focuses on the important role and contribution that biodiversity and the 1992 United Nations Convention on Biological Diversity can make to ongoing efforts and processes to reduce poverty, hunger, disease and environmental degradation worldwide. Damage to ecosystems, species and habitats, and the loss of biodiversity can and will have a serious impact on human health and development. The future of human development will be closely affected by individual choices and political decisions in industrialized countries. Governments, international financial institutions, the private sector, intergovernmental organizations and non-governmental organizations need to take action to meet their global responsibilities regarding biodiversity conservation, poverty reduction and sustainable development, and their responsibilities to present and future generations.  相似文献

ABSTRACT

This introduction provides a conceptual and theoretical background to the more detailed analyses contained in the articles of the Special Section. The introduction firstly presents a critical overview of the rise of resilience and its increasing role in shaping the terms of international interventions. It identifies a set of interrelated conceptual themes relevant to theorising the relationship between resilience and peacebuilding and evaluates how appropriate a resilience approach might be in promoting sustainable peace and what might be its main dangers and pitfalls.  相似文献

ABSTRACT

This paper discusses the sentencing purposes for penal penalties, judges’ perceptions of sentencing purposes and prison sentences, and the effects of penal sanctions. We examine judges’ positions towards different penalties, with a focus on imprisonment, since their views on the different penalties are related to their sentencing decision-making. Understanding these views is then critical for several practical and political purposes, including bridging the gap between academic discourse and legal practice. We accessed judges’ views on penal sanctions through a questionnaire and an interview. Our sample is compounded by the judges of the criminal courts from the three major cities in Portugal. Despite the most recent criminological empirical knowledge, judges valued imprisonment as the most adequate sentence, both for different crimes and for different judicial purposes. This result is not consistent with viewing imprisonment as a ‘last resort’ solution. Indeed, we did not find this ‘last resort’ position in our data, and it is not apparent in the judicial statistics on imprisonment rates. Our data highlight the importance of increasing judges’ training on criminological and sociological issues as well as the importance of changing the influence of their personal beliefs regarding penal sanctions into research-based positions.  相似文献

Abstract

Using survival models, we test whether short-term changes in the labour market affect poverty duration. Data are from the Brazilian Monthly Employment Survey. Such a monthly dataset permits more accurate estimations of events than using annual data, but its panel follows households for a short period. Then methods that control for both right- and left-censoring should be used. The results are as follows: households with zero income are not those with the lowest chances of exiting; changes in aggregate unemployment do not affect poverty duration; and increasing wages in the informal sector has a negative effect on poverty duration.  相似文献

The aim of this study is to analyse the effects on sex workers of new regulations that ban the practice of street prostitution in Spain. This country has not traditionally maintained a clear policy regarding prostitution. However, in recent years there has been a clear turn towards the criminalization of behaviours related to voluntary prostitution. The city councils of several Spanish cities have banned the practice of street prostitution and sanctioned it with fines issued to both prostitutes and clients. Even if few studies on prostitution have been carried out in Spain, none of them had yet analysed the effects of the adoption of civic ordinances on sex workers.In this paper we present the results of an empirical research carried out with a sample of 79 sex workers – in 20 cases with in-depth interviews – to explore the effects of the new regulation on their labour conditions.  相似文献

An interdisciplinary study was conducted in the Kailash Sacred Landscape region in north-western Nepal, to explore opportunities for, and barriers to, sustainable tourism as an adaptation strategy, not only for reducing community vulnerability to climate change but also as a poverty–alleviation measure. Whilst the primary focus was on interactions between tourism and climate change, the study revealed a highly complex system, with many social, economic, environmental, and institutional drivers involved. In order to bring some clarity and consistency in the exploration of these complex interactions in context, elements of the policy sciences, primarily problem orientation, were utilised. The exploratory nature of the study, including its objectives and intended use, meant that goal clarification and analyses of trends were based on limited available information. Despite these shortcomings, the study was able to elucidate and clarify on important factors to consider in consultation with relevant participants. Diversification of livelihood options as well as preserving local culture were found to be highly valued—both by the local communities that were consulted as well as for those advocating for a tourism experience that is unique to this region. Harmonising these valued outcomes could be achieved by incorporating and legitimising local traditional knowledge. Insights into further collaboration on the issue of valued outcomes would strengthen and support the knowledge base for an appraisal of possible development pathways.  相似文献

Research on the fulfilment of electoral promises has been particularly fruitful over the past decades. Most of it focused on examining pledge fulfilment at the cabinet level, and little emphasis was placed on the reasons underlying the level of compliance. As a consequence, core factors in explaining pledge fulfilment have not yet been explored. One such factor might be instability in a government's internal functioning. We argue that ministerial instability is relevant for explaining a government's broken promises, and that its importance increases at the junior minister level and among the most salient ministries. Relying on data on the fulfilment of electoral promises and ministerial instability in Portugal between 1995 and 2019, backed by interviews with former ministers and junior ministers, we provide evidence that the fulfilment of electoral promises is significantly influenced by portfolio volatility, particularly at the junior ministerial level and in the most important ministries.  相似文献
