Ambiguities of xenophobia in a border town: inner city informal traders and Ekasi shopkeepers in the city of East London,South Africa

ABSTRACT

This paper explores the livelihoods, experiences and identities of immigrant informal traders and shopkeepers in the Buffalo City Metropolitan area, which encompasses the centres of East London, Mdantsane and King Williams Town. We primarily use a socio-spatial perspective to analyse informal activity, and offer a particular perspective on how informality has encouraged a type of ‘informal citizenry’ among traders. We argue that informal trading has a very particular history in the region, and that East London’s notoriety as a ‘border city’ and a regional frontier has created a fractured space, which is best expressed through the experiences of migrants and entrepreneurs. We point out that informality is a driver of economic empowerment and equality among traders, but also of xenophobia and difference.     

Macroscopical estimation of the post mortem interval (PMI) and exclusion of the forensically relevant resting period--a comparison of data presented in the literature with recent osteological findings

The aim of the present study was to determine to what extent macroscopical parameters mentioned in the literature are suitable for the estimation of the post mortem interval (PMI) and particularly for the exclusion of the forensically relevant resting period for recent bone material. The macroscopical examination of recent bone material with a known PMI showed that only one published parameter (relics of adipocere in the cross section of the compacta) was consistent with our findings for this particular resting period (27-28 years). Other macroscopical parameters presented in the literature were contradictory to the results observed in this study. Among those are the rigidity of bones, the adhesion of soft tissue, the filling of the marrow cavity, and the permeation of the epiphyses with adipocere. Concerning the exclusion of the forensically relevant resting period, a similar result was observed. This study identified some diagnostic findings in bones with a resting period of less than 50 years which according to the literature should only be present after a resting period of more than 50 years. These features included the lack of macroscopical traces of adipocere, degradation of the compacta surface, detachment of the cortical substance, the ability of bone to be broken with bare hands, and superficial usures. Moreover, in one-third of our cases we identified some intra-individual differences not previously described in the literature. In addition to the other results, those intra-individual differences make an estimation of the PMI more difficult. However it should be noted that those published parameters were collected from bone material which was stored in a "relatively arid sand-grit-clay soil of the broken stone layer of Munich". The bones in the present study were stored in acidic and clayey-loamy soil, partly with lateral water flow. In conclusion, the present study demonstrates that one should use caution estimating the post mortem interval and excluding the forensically relevant resting period, even when all available results are considered.     

History of Traumatic Abuse and HIV Risk Behaviorsin Severely Mentally Ill Substance Abusing Adults

Epidemiological studies in the United States estimate HIV seroprevalence rates ranging between 4% and 23% for serious mentally ill adults (SMIA; i.e., schizophrenia, bipolar disorder, and other chronic disorders with psychotic features), with substantially greater estimates for risky sexual behaviors. Among the most consistent factors linked to HIV risk in non-SMIA populations is a history of emotional, physical, or sexual abuse. The current study examined the intersection of abuse history and HIV sexual risk behavior in SMIAs with a group of men (n = 64) and women (n = 115) recruited from eight geographically diverse and representative clinical sites around Florida. A cross-sectional interview revealed a high prevalence of alcohol and other drugs problems, as well as a history of emotional, physical, or sexual abuse in 75% of the participants, with 68% of these reporting multiple types of abuse. Compared to nonabused counterparts, those with a history of abuse reported significantly greater: (a) lifetime and current psychiatric symptoms, (b) recent unprotected sexual intercourse, and (c) crack cocaine, heroin, and marijuana use. No gender differences were detected in the associations of abuse history and sexual risk behaviors. These results underscore the need for HIV prevention efforts targeted to SMIAs and the critical importance of addressing abuse history in interventions with this underserved population.     

INCREASING PRODUCTIVITY OF GOVERNMENT'S RELIANCE UPON OUTSIDE ORGANIZATIONS TO PROVIDE ANALYSIS AND MANAGEMENT SERVICES

The federal government spends vast sums of money for management and analysis services. The authors contend that the selection process to determine the winners of the awards of contracts to perform these services too often disregards cost competitiveness as a factor in the award. The relative importance of technical proficiency and cost are examined and a model is proposed whereby a high level of technical expertise can be obtained at a more reasonable cost.
