Democracy,social capital and school governing bodies in South Africa

Critics of school governing bodies (SGBs) – both on the left and on the right – tend to rely upon arguments that ignore significant portions of the act that created SGBs – the South African Schools Act (SASA) – the exact nature of the changes to SGBs wrought by amendments to the act and the manner in which the courts, in interpreting the act, have both reinforced the autonomy of SGBs at the same time as they have set limits on those powers. The authors’ reading takes seriously all of the provisions of SASA, its amendments and various court constructions of SASA's provisions. This close reading of the South African Constitution, SASA, SASA's amendments and the case law reveals the lineaments of a fourth level of democratic government. Even with their uneven success as a fourth tier of democratic government, SGBs reflect, in many respects, the most important interactions that citizens have with the state. The authors contend that SGBs provide a vehicle for popular political participation that is quite real, and that participation is made no less real by the strictures imposed upon them by South Africa's constitutional and regulatory order. Despite concerns about their lack of capacity, SGBs enjoy popular acceptance and participation across class and language divides. The legal status of SGBs does not merely enhance various forms of local democracy, SGBs also maintain and create effective social networks that generate new stores of social capital. The ability to provide new forms of democratic participation and to create new stores of social capital suggests that SGBs have the makings of a great, new and rather unique ‘South African’ political institution.     

Popular evaluations of election quality in Africa: Evidence from Nigeria

Despite the important consequences of citizens' election quality perceptions on political behavior and political attitudes, very little is known about how citizens formulate their perceptions of election quality. In this paper, I assess the correlates of citizens' perceptions of election quality. I suggest that the performance of election-related institutions is an important correlate of citizens' election quality perceptions. However, citizens' experience with electoral irregularities, and partisan affiliation also matter. I test these hypotheses in the context of the 2007 Nigerian general elections using survey data from Afrobarometer and International Foundation for Electoral Systems. The findings provide robust support for the hypotheses. Most importantly, the results indicate that the performance of electoral management bodies is associated with citizens' assessment of election quality in Africa and that citizens demand electoral management bodies with impartiality and professionalism.     

A new strategy for the discrimination of mitochondrial DNA haplogroups in Han population

Mitochondrial DNA (mtDNA) haplogroup discrimination is interesting not only for phylogenetic and clinical but also for forensic studies. We discriminated the mtDNA haplogroups of 570 healthy unrelated Han people from Zhejiang Province, Southeast China, by comprehensive analysis mutations of the hypervariable segments-I sequence and diagnostic polymorphisms in mtDNA coding region using real-time polymerase chain reaction (RT-PCR), which was compared with the widely used PCR and restriction fragment length polymorphism (PCR-RFLP) method. The results showed that in superhaplogroup M, haplogroup D was the most common haplotype within this assay to 24.6%, and in the other superhaplotype N, haplogroup B and F were the most common groups. Samples re-identified by PCR-RFLP showed the consistent results that were got with RT-PCR. In conclusion, the RT-PCR strategy appears to be an accurate, reproducible, and sensitive technique for the discrimination of mtDNA haplogroups, especially for mass screenings quickly and economically.     

地方蛋鸡群中A亚群禽白血病病毒的分离与全基因组序列分析

Cross-sectional anthropometric study of the external ear

This cross-sectional anthropometric study was aimed at estimating expansion of the external ear during adult life, in order to evaluate the extent to which anatomical features appearing in earprints may vary with time. A review of the literature was provided. Data extracted from photographed ears of 1353 subjects were analyzed. The effect of age on auricle length, earlobe length, and auricle width was explored using univariate analyses of variance. The regression coefficients of age on these dimensions were, respectively, 0.178, 0.115, and 0.073 mm/yr for males, and 0.162, 0.100, and 0.073 mm/year for females (p=0.000). Regression coefficients of age corrected for stature were assumed to be less accurate. Anthelix prominence and helix width were analyzed using data of 175 subjects, and appeared unaffected by age. As lobe expansion appeared to exceed the estimated cartilage expansion, it was assumed that particularly the imprint of the lobe would be less stable with time.     

Sustained Combustion of Bodies: Some Observations*

Abstract: Previous tests have explored the fire effects and fuel characteristics of animal carcasses in intense fires of relatively short duration. Here, test fires were conducted involving intact human cadavers and torsos that included nonaccelerated, long‐duration fires involving the bedding and clothing (in the manner of typical accidental deaths). The objective was to observe the fire conditions (size, radiant heat flux, and duration), where a human body represented the major fuel package in a nonaccelerated fire. The pattern of damage to the body was documented and compared with that resulting from a furnished room fire. Two intact, unembalmed human cadavers were exposed to fires of simulated accidental origin. The bedding was ignited by an open flame, and the fires were allowed to burn unaided to self‐extinguishment. It was found that normal human bodies can support a modest‐sized fire for some 6–7 h under these conditions. The presence of a substrate material that can act as a wick for the combustion of the rendered body fat results in extensive destruction of the torso where the greatest amount of subcutaneous fat resides, with less damage to the head and limbs. A third (partial) cadaver was exposed to a recreation of a typical accidental fire in a furnished room that progressed to full room involvement. This fire of some 15 min of total duration inflected only surface‐layer damage to the torso of the victim.     

Stature estimation from tibia percutaneous length: New equations derived from a Mediterranean population

Stature is a fundamental anthropometric character to trace the biological profile of a person. In some cases, when dismembered or mutilated bodies are discovered in a forensic context, it is essential to estimate stature from single districts of the body. Nevertheless, to date and worldwide, there are only few population-specific studies on stature estimation from leg length and none of them concerns modern populations in southern Europe. We attempted to fill this gap, focusing on the estimation of stature from the length of the tibia in a Mediterranean population (Italians). We carried out the current study on a sample of 374 Italian university students of both sexes (age range: 19.9–34.4). Both, actual stature and percutaneous length of tibia were measured and new equations were developed for stature estimation. We tested separate regression equations for each sex, as well as an equation for remains, whose sex is unknown. To assess their reliability, the equations were tested on a holdout sample of 30 individuals from the same population. Moreover, results of new specific linear regression equations were compared to others from the literature. We demonstrated that the newly proposed formulae (for males and combined sexes) and the ones by Olivier (for females) provided the most reliable estimations of stature for southern Europeans.     

《行政许可法》对地方立法的影响

行政许可法颁布和施行的意义不仅仅局限于行政法治这一领域,而且以独特的视角为地方立法今后的发展提供了难得的参考。在地方立法理念上的变化体现为:平衡公益和私益,追求效益,立法应务实创新;对地方立法体制及立法技术的影响表现为:地方对行政许可设定具有很强的局限性,地方立法主体需重新认识和定位,注重以立法事项的性质确定立法主体,在权限上既赋予地方一定的专有立法权,同时对地方立法权进行一些具体的禁止作为补充,健全地方立法的具体内容,完善地方立法技术。即便如此,行政许可法仍对地方立法可能造成以下负面影响:首先是借行政许可法留下的可观的立法空间,扩大地方立法权;其次是由于行政审批改革与立法同步,立法中部门利益将会反弹。

The application of geographic information systems and spatial analysis to assess dumped and subsequently scattered human remains

This study utilizes geographic information systems (GIS) and spatial analysis (SA) technology to address the problems associated with prediction of location and effective recovery of dumped and scattered human remains in Louisiana. The goals are to determine if a selective bias exists in Louisiana as to where and when human remains are dumped and to assess whether or not geographically specific patterns exist in the dispersal of human remains. We hypothesized that a positive relationship exists between postmortem interval (PMI) and dispersal distance, and that there are negative relationships between PMI and dispersal direction and between dispersal direction and distance. Our results indicate that, in Louisiana, remains are more often dumped in rural areas away from a structure, and are found within (1/4) mile of the nearest road. For Louisiana, no seasonal bias was found in the analysis of when remains are dumped. Furthermore, with the exception of the relationship between PMI and the shortest distance remains were dispersed, no geographically specific patterns were detected in the analyses of dispersal distance, dispersal direction, and PMI.
