A rapid method for evaluating suspect testimony is valuable at any stage in an inquiry and can result in a change of direction in an investigation. Rape cases, in particular, can present problems where a defendant renders DNA analysis redundant by claiming that the claimant consented to have sexual relations. Forensic palynology is valuable in confirming or eliminating locations as being crime scenes, thus checking the testimony of both parties. In contrast to some forensic disciplines, forensic palynology can provide critical information without time-consuming full analysis. Two cases are described where the palynological assemblages from comparator samples of pertinent places were compared with those obtained from clothing of claimants and defendants. The results of rapid microscopical scanning of relevant preparations led to early confessions, thus obviating the need for costly analyses and protracted court proceedings. A third case demonstrates the unbiased nature of this technique where a man, although innocent of any offense, lied about having visited the crime scene for fear of prosecution. This highlights the need for sensitive policing in claims of rape.  相似文献

Abstract

Processes of deregulation and privatisation have been gradually transforming the familiar residential and tenurial structures of English cities. Patterns of access to housing have changed and, to varying degrees, the social composition and social roles of neighbourhoods. This paper explores some aspects of these changes in three types of residential area, examines some of the interconnections and indicates the ways in which these changes link to broader and more fundamental social transformations.  相似文献

Smallholdings in the rural areas of northwest Syria are a result of land fragmentation that is due to inheritance. Because of rapid population growth combined with land fragmentation, these smallholdings are increasing and cannot sustain the rural households whose sizes and needs are also increasing rapidly This situation has led to increasing numbers of males migrating to urban areas in Syria and to neighbouring countries looking for work opportunities. In addition, recent agricultural intensification trends seem to have led to the emergence of a waged labour force which, in the absence of male workers owing to significant rates of migration, is now predominantly female. Agricultural labour use depends upon household characteristics and resources (type of labour used, gender of labour waged/exchanged/familial). The article attempts to present a comprehensive analysis of household labour use in distinctive farming systems in one region of Syria that has undergone great change in recent decades, and examines the changes in the composition of the agricultural labour force. Secondary information, rapid ural appraisals and formal farm surveys were used to gather information on the households in a study area where different farming systems coexist. The results show that the decrease in landholding size, the resulting male migration, and land intensification have resulted in the expansion offemale labour in agriculturalproduction, which has been termed in this research a 'feminization of agricultural labour'. This suggests that agricultural research and extension services will have to work more with women farmers and farm workers, seek their wisdom and involve them in technology and transfer. This is not easy in conservative societies but requires research and extension institutions to take this reality into consideration in their programmes.  相似文献

This article addresses theoretical issues concerning differentiation and class formation using North American data. It explores how socio‐economic characteristics vary and impact survival in agriculture. The study is based on panel data collected from a sample of smallholders in three Piedmont North Carolina counties. Factor analysis reveals five major dimensions of differentiation: scale, household labour, off‐farm family labour and income, demographic characteristics, and land tenure. An index of propensity to survive in agriculture, constructed from three waves of panel data is regressed upon five indices measuring the underlying dimensions of differentiation. Land tenure manifests a statistically significant net effect on survival in agriculture. These empirical results support theoretical arguments in favour of integrating analyses of socio‐economic and demographic differentiation in the study of agricultural enterprises.  相似文献

Abstract: The past two decades have witnessed significant changes in Canadian federalism and intergovernmental relations. This article investigates how developments in federalism and public administration in the 1990s have affected intergovernmental administrative machinery and the formal and informal structures, functions, and resources of intergovernmental relations compared to findings from the 1980s. Using a survey, interviews with senior intergovernmental officials, and government documents, this paper examines the evolution of the intergovernmental administrative state as opposed to the political realm of executive federalism. The authors outline how the formal structures and functions of intergovernmental agencies and officials have evolved and argue that informal intergovernmental networks are very important in understanding and explaining the capacity of the federation to meet current and future policy and administrative challenges. Sommaire: Au cours des deux dernières décennies, d'importants changements se sont produits au sein du fédéralisme et des relations intergouvernementales au Canada. Le présent article examine comment les récents développements intervenus dans le fédéralisme et l'administration publique dans les années 1990 ont affecté les rouages administratifs intergouvernementaux et les structures officielles et non officielles, ainsi que les fonctions et ressources des relations intergouvernementales au cours de deux dernièves décennies comparativement aux résultats des années 1980. A l'aide d'un sondage, d'interviews de hauts fonctionnaires intergouvernementaux et de documents gouvernementaux, cet article étudie l'évolution de l'État administratif intergouvernemental par opposition au domaine politique du fédéralisme exécutif. Les auteurs ébauchent la façon dont les structures et les fonctions officielles des organismes et des hauts fonctionnaires intergouvernementaux ont évolué et soutiennent que les réseaux intergouvernementaux non officiels sont très importants pour comprendre et expliquer l'aptitude de la fédération à relever les défis politiques et administratifs présents et futurs.  相似文献
