In recent years understanding of poverty and of ways in which people escape from or fall into poverty has become more holistic. This should improve the capabilities of policy analysts and others working to reduce poverty, but it also makes analysis more complex. This article describes a simple schema which integrates multi-dimensional, multi-level, and dynamic understandings of poverty, of poor people's livelihoods, and of changing roles of agricultural systems. The article suggests three broad types of strategy pursued by poor people: ‘hanging in’, ‘stepping up’, and ‘stepping out’. This simple schema explicitly recognises the dynamic aspirations of poor people, diversity among them, and livelihood diversification. It also brings together aspirations of poor people with wider sectoral, inter-sectoral, and macro-economic questions about policies necessary for the realisation of those aspirations. 相似文献

The analysis of mitochondrial DNA (mtDNA) is a useful tool in forensic cases when sample contents too little or degraded nuclear DNA to genotype by autosomal short tandem repeat (STR) loci, but it is especially useful when the only forensic evidence is a hair shaft. Several authors have related differences in mtDNA from different tissues within the same individual, with high frequency of heteroplasmic variants in hair, as also in some other tissues. Is still a matter of debate how the differences influence the interpretation forensic protocols. One difference between two samples supposed to be originated from the same individual are related to an inconclusive result, but depending on the tissue and the position of the difference it should have a different interpretation, based on mutation-rate heterogeneity of mtDNA. In order to investigate it differences in the mtDNA control region from hair shafts and blood in our population, sequences from the hypervariable regions 1 and 2 (HV1 and HV2) from 100 Brazilian unrelated individuals were compared. The frequency of point heteroplasmy observed in hair was 10.5% by sequencing. Our study confirms the results related by other authors that concluded that small differences within tissues should be interpreted with caution especially when analyzing hair samples. 相似文献

Some years ago the doctor was seen as the one who "knows better", and it was absolutely unconceivable that the patient could refuse the suggested treatment or even ask any questions about it. Differently, nowadays doctors face demands to keep their patients informed and can even be sued when they act without patient knowledge and consent. On the patient's side this new paradigm does not necessarily legitimate euthanasia--still criminally forbidden in most parts of the world--but allows some kind of personal power over body, health and life, materialized in advance directives. On the doctor's side, it entails a change in the list of good medical practices, imposing the doctrine of informed consent and the prohibition of dysthanasia. 相似文献

In this article, we discuss the experiences of six female secondary-school students participating in a media group that encouraged critical discussion and analysis of gender, particularly with respect to notions of strong women in popular media texts. Throughout the study, the participants viewed various forms of media and critically discussed gender representations. We describe the ways that we encouraged critical discussion that prompted the participants to challenge dominant perspectives and develop personal positions regarding gendered representations in popular media. Many discussions were convoluted and often contradictory. Throughout these debates, however, moments emerged in which participants identified complexities associated with gendered representations of strong women as related to privilege, beauty ideals and autonomy. We identify these moments as messy yet critical, requiring the researchers to challenge participants’ postfeminist notions of strong women. We emphasize the importance of ongoing dialogue and the potential of media for encouraging discussion. 相似文献

In this study we examined the effects of risk factors (perceived neighborhood crime/delinquency problems, neighborhood incivilities)
and protective factors (teacher support, family support, peer support) on the school engagement of 123 urban adolescents of
color. Age and gender were also examined to determine if different ages (younger or older) or genders (male or female) significantly
modified the relationship between the risk factors and school engagement. Results indicated that perceived neighborhood incivilities
was uniquely predictive of school engagement. Contrary to hypotheses, different levels of the perceived social support variables
did not modify the effects of risky neighborhood conditions on adolescent’s perceived school engagement. Age, but not gender,
significantly modified the relationship between perceived family social support and perceived neighborhood crime on adolescents’
reported levels of school engagement. The implications of the results for prevention and intervention programs that address
school engagement among early adolescents of color are considered.

The system of teacher induction appeals as introduced by the Teaching and Higher Education Act 1998 is yet to be fully implemented. The appeals system envisaged by both the Act and subsequent regulations is still evolving and matters are made more complex by the fact that the appeals will be part of the General Teaching Council's (GTC) functions in due course. The Department for Education and Employment has had the unenviable task of drafting detailed procedures which may, or may not, be adopted by the GTC. The department's system of appeals may only apply for six months before the GTC review which may not be time enough to properly evaluate the various procedures. This article attempts to set out the current procedure and to offer some thoughts on areas which may need to be carefully monitored by both the department and the GTC. 相似文献

Transnational adoption and child migration are often regarded as recent phenomena, yet there is a long history of children travelling without their families, settling and integrating in a foreign culture and environment. In the 1920s, thousands of Hungarian children went to Belgium for a six-month holiday within the framework of a humanitarian project. Although they were supposed to return to Hungary after their vacation, some of them stayed indefinitely with their Belgian families. By analyzing oral testimonies of the now elderly ‘children’ about their migration and childhood experiences in Belgium, we explore how they construct and reconstruct concepts such as childhood, vulnerability, and loyalty commitments, and show the crucial importance of maintaining birth family ties for the future development of transnationally adopted children. 相似文献

Public service motivation (PSM) is a focal construct in public management research, and while sound evidence exists that PSM is positively associated with several desired outcomes, knowledge on the underlying mechanisms which explain these associations and on potential negative consequences of PSM remains limited. Addressing these research gaps, this study investigates how PSM relates to relational job resources, work engagement, and outcomes. We thereby account for both direct and moderating effects of PSM and consider positive (employee performance) and negative outcomes (sickness absenteeism and presenteeism). We empirically test our model in the German public sector and find that the PSM dimensions relate differently to the assessed outcomes, providing varying support for our hypotheses. In particular, commitment to public value and compassion seem to drive the positive effect of PSM on employee performance, whereas self-sacrifice and client orientation are linked to reduced absenteeism, and only compassion is associated with increased presenteeism. 相似文献
