Exploring poverty traps and social exclusion in South Africa using qualitative and quantitative data
Recent theoretical work hypothesises that a polarised society like South Africa will suffer a legacy of ineffective social capital and blocked pathways of upward mobility that leaves large numbers of people trapped in poverty. To explore these ideas, this paper employs a mix of quantitative and qualitative methods. Novel econometric analysis of asset dynamics over the 1993–98 period identifies a dynamic asset poverty threshold that signals that large numbers of South Africans are indeed trapped without a pathway out of poverty. Qualitative analysis of this period and the period 1998–2001 more deeply examines patterns of mobility, and confirms the continuation of this pattern of limited upward mobility and a low-level poverty trap. In addition, the qualitative data permit a closer look at the specific role played by social relationships. While finding ample evidence of active social capital and networks, these are more helpful for non-poor households. For the poor, social capital at best helps stabilise livelihoods at low levels and does little to promote upward mobility. While there is thus some economic sense to sociability in South Africa, elimination of the polarised economic legacy of apartheid will ultimately require more proactive efforts to assure that households have access to a minimum bundle of assets and to the markets needed to effectively build on those assets over time. 相似文献

A Molecular Method to Detect Wound Cells in Bloodstains Resultant of Sharp Force Injuries for Crime Scene Reconstruction 下载免费PDF全文
Donald J. Johnson M.S. David E. Raymond Ph.D. Cynthia Chen M.S. Matthew Quon M.S. Julian Lis M.S. Mo Re Choi M.S. Christopher Lopez M.S. Aileen Han Ray D. de Leon Ph.D. Cynthia Bir Ph.D. 《Journal of forensic sciences》2018,63(3):842-848
Previous research by the authors on an animal model showed that bloodstains can contain additional information about their somatic origin in the form of wound cells. Bloodstains produced by a gunshot wound to the head were distinguished from bloodstains produced by a gunshot wound to the chest by testing the stains for a brain microRNA marker. In this study, the effectiveness of the technique was examined on blood drops shed externally from a stab wound to the liver of rat carcasses. Specifically, investigations were conducted on the liver microRNA marker, rno‐mir‐122‐3p, with the QIAGEN miScript System, and PCR analysis. Between the two stabbing methods used, 67% of the scalpel blades and 57% of the blood drops tested positive for rno‐mir‐122‐3p; however, other samples tested negative giving inconclusive results as to the wound‐of‐origin. The amount of the liver cells in the bloodstains appeared to be related to the extent of trauma. 相似文献
