The frontier revisited: displacement,land and identity among farm labourers in the Sundays River Valley

This paper aims to unpack the dynamics of displacement and the relationship of physical movement to elements of space (i.e. land) and place (or identity), in the Sundays River Valley, near the town of Kirkwood, in the Eastern Cape, South Africa. It primarily uses the motif of frontiers to cast light on displacement as an ongoing phenomenon and explore the different eras of occupation of land in the Sundays River Valley, from the early nineteenth century until 1970. It relates different layers of belonging and identity to the unfolding of capitalism and apartheid in South Africa. The article argues that ties to land are multiple, contested and based upon dispossession and physical movement rather than upon stability. While such a high degree of contestation of oral evidence in the Sundays River Valley might not give current claimants a detailed legal basis for restitution, it is an academically valuable idea to explore the origins of the inhabitants in the Sundays River Valley – because it can indicate the degree to which local identities are influenced by experiences of disruption and displacement. The paper argues that frontier relationships in the SRV are central in the formation of larger systems of relationships of race and class, and that this casts new light on displacement (both as a historical event and a contemporary experience), in the formation of identity and place in southern Africa.     

Histomorphological features of gunshot injuries to the calvarian bone in nephrogenic osteopathy

This histological study of calvarian bones with the injuries inflicted by a shot from an Osa traumatic non-lethal pistol revealed nephrogenic osteopathy in the preceding period. The pathologically altered bone tissue was damaged by a relatively mild tangential traumatic impact. It is concluded that the possibility of such pathological changes should be taken into consideration in the forensic medical expertise of any trauma including gunshot injuries.     

Sex estimation from the mastoid process among North Indians

Determination of sex from fragmentary crania is a critical problem in forensic anthropology. Osteometric analysis of mastoid can serve forensic anthropologists better in sex identification by virtue of the noticeable dimorphic characteristics. The present study aims to develop population-specific, sex-differentiating anthropometric standards for the mastoid process of North Indian skulls. Eight parameters of the mastoid region were measured on 138 adult crania (M/F 104:34, 22-65 years) and analyzed using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.000). In stepwise analysis, asterion-mastoidale and mastoid breadth have provided an accuracy of 87%. Receiver operating characteristic curves were obtained for each variable to observe their overall performance in sex determination. Posterior end of incisura mastoidea-depression of suprameatal triangle was found to be the best variable with maximum area under curve and highest predictive accuracy (82.6%).     

Delayed left anterior and middle cerebral artery hemorrhagic infarctions after attempted strangulation: a case report

The 2 common carotid arteries bifurcate in the neck into the internal and external carotid arteries. The internal carotid artery enters the skull and further divides into the anterior and middle cerebral artery. During its short course in the neck, the carotid artery travels encased in the carotid sheath along with the vagus nerve and the internal jugular vein. During its course in the neck, the carotid artery is quite superficial, making it vulnerable to both penetrating and blunt traumatic injuries. We report here a case of a 40-year-old man who presented to the emergency department after sudden collapse and loss of consciousness a day after an attempted strangulation. Imaging revealed large hemorrhagic infarcts in the left anterior cerebral artery and middle cerebral artery territories as well as a smaller infarcts in the right anterior cerebral artery territory necessitating emergency decompressive hemicraniectomy. Our case report adds to the existing literature on nervous system injury due to strangulation. Physicians should be aware of the possibility of delayed presentation of neurological deficit after attempted strangulation.     

Evaluation of histologic changes of the skin in postmortem period

ABSTRACT: Determination of the time of death is an important consideration in forensic practice. Many methods have been attempted to accurately and systematically determine the postmortem interval (PMI). Histologic examination of the skin or appendages is one of the methods tried by few researchers. However, no attempt had been made to analyze the histologic changes in the skin and appendages simultaneously and to compare them with PMI. We sequentially studied the histologic changes of the skin and appendages in the early PMI. The results of the present study show that the skin undergoes progressive morphological changes in the postmortem period. The epidermis and the dermis appeared normal for 6 hours after death, and after this period, degenerative changes began. By 6 to 9 hours after death, degeneration began in the dermis, and by the end of 18 hours, the dermis began to disintegrate. The sweat glands appeared normal for approximately 3 to 4 hours. For 18 hours after death, the sebaceous glands and hair follicles appeared normal, and after this period, degeneration began.     

Dichroism measurements in forensic fibre examination. Part 4-dyed acrylic and acetate fibres

A number of dyed acrylic and acetate fibre samples were examined with plane polarized light on their dichroic behavior by optical light microscopy (OLM) and microspectrophotometry with plane polarized light (MSP-PPL). It was found that most of these low birefringent fibres possess weak dichroic effects that are very hard to observe with microscopy. However, using MSP-PPL, the linear dichroism could be measured. A comparison between the dichroic effects found for the same disperse dyes on triacetate (TrAc), diacetate (Ac), polyester (PES) and polyamide (PA) shows that the linear dichroism follows the order: PA>PES >TrAc, Ac.     

Organizational Readiness for Change in Correctional and Community Substance Abuse Programs

Significant needs exist for increased and better substance abuse treatment services in our nation's prisons. The TCU Organizational Readiness for Change (ORC) survey has been widely used in community-based treatment programs and evidence is accumulating for relationships between readiness for change and implementation of new clinical practices. Results of organizational surveys of correctional counselors from 12 programs in two states are compared with samples of community-based counselors. Correctional counselors perceived strong needs for new evidence-based practices but, compared to community counselors, reported fewer resources and less favorable organizational climates. These results have important implications for successfully implementing new practices.     

网络犯罪分析:用户及系统的多视图分析方法

近年来网络犯罪数量呈快速上升的势头,但是却缺乏一种有效的取证方法来处理这些案件.调查人员通常依靠调查大量繁琐的源代码来了解犯罪模型及提取证据,但这种方式需要很多的人力与时间,并可能导致人为错误.为了克服调查人员可能出现的这些潜在错误,我们在本文中提出了一种半自动的方法来解决这些问题.该方法集成了用户视图(基于取证调查人员的高级别研究)和系统视图(基于对源代码的自动分析),来帮助调查人员精确调查的范围.本文应用此方法分析了一个真实案件,证明了方法的可行性,同时帮助调查人员高效地确定了调查范围和犯罪模型.可见这种半自动方法可以对大量有多个来源的电子证据进行有效分析,提高了网络犯罪案件取证的效率和可靠性.     

Geophysical Monitoring of Simulated Clandestine Graves Using Electrical and Ground‐Penetrating Radar Methods: 0–3 Years After Burial*,†

Abstract: This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated “wrapped” and “naked” burials were created. Multigeophysical surveys were collected over a 3‐year monitoring period. Bulk ground resistivity, electrical resistivity imaging, multifrequency ground‐penetrating radar (GPR), and grave and background “soil‐water” conductivity data were collected. Resistivity surveys revealed the naked burial had consistently low‐resistivity anomalies, whereas the wrapped burial had small, varying high‐resistivity anomalies. GPR 110‐ to 900‐MHz frequency surveys showed the wrapped burial could be detected throughout, with the “naked” burial mostly resolved. Two hundred and twenty‐five megahertz frequency GPR data were optimal. “Soil‐water” analyses showed rapidly increasing (year 1), slowly increasing (year 2), and decreasing (year 3) conductivity values. Results suggest resistivity and GPR surveys should be collected if target “wrapping” is unknown, with winter to spring surveys optimal. Resistivity surveys should be collected in clay‐rich soils.
