ABSTRACT

While marrying was an expected event in 19th-century Western society and has been subject to much historical research, there are few studies on how disabilities influenced people’s marriage patterns and spouse selection. The aim of this analysis is to contribute clarification on this issue by examining with whom disabled men and women married and the marital age and socio-demographic characteristics of them and their spouses. In total, 188 disabled individuals born in the first half of the 19th century and who married in the Sundsvall region, Sweden, are studied. The results reveal that disabled men and women did not marry each other, and they entered into marriage at a slightly higher age than the average, although there was usually no marked age gap between them and their spouse. Endogamous patterns were primarily found regarding the socio-spatial background of the two spouses. This analysis is one of the few studies identifying the marriages among a comparatively large number of disabled people using demographic data. Their participation in the partner pool highlight their agency historically and emphasize that disability did not lead to distance from social life in past society.  相似文献

ABSTRACT

In this study, we contributed on research of policing cyberspace by analysing how different stakeholder groups (nodal clusters) participate in the formal security network during detecting and handling of data system break-ins in practice. The goal of this article was to study whether citizens have roles within the security network. The analysis was based on data system break-ins (n = 220) reported to the Finnish national computer emergency response team, CERT-FI, in 2012. We detected five types of nodal clusters: computer emergency response teams (CERTs), companies, public organisations, private persons and associations. The roles of nodal clusters were described by using cultural, social, political, economic and symbolic capital. However, the results show that there are differences not only between the nodal clusters but also inside them regarding their positioning within the network. We argue that instead of a type of nodal cluster, division based on the roles and individual needs could be more relevant. Recognition of roles could encourage netizens to co-produce cybersecurity from their respective premises.  相似文献

This paper aims to advance knowledge about corporate environmentalism by using new concepts and methods. We broaden the concept of the firm as “differentiated composite actor” by including not only managers but workers and unionists as actors. We descend into the “hidden abode of production” using Lefebvre’s concept of “everyday life” to explore the barriers environmental policies experience in this sphere. We base our explorations on life-history interviews to understand how the imaginaries of production are embedded in people’s self-conceptions. We identify seven barriers to the implementation of environmental practices: deficient regulations, collusion between controller and controlled, de-prioritisation, hierarchism, compartmentalisation, specialisation, and social unsustainability. A “necessity discourse,” legitimating the priority of efficiency and product quality over environmental sustainability, subjugates alternative sustainable practices. The paper concludes with a discussion of the results in the light of previous investigations, suggesting that the concept of the everyday could enrich future research.  相似文献

Participatory policies seeking to foster active citizenship continue to be dominated by a territorial imagination. Yet, the world where people identify and perform as citizens is spatially multifarious. This article engages with the tension between territorially grounded perceptions and relational modes of practicing political agency. Studying empirically the Finnish child and youth policies, we address jointly the participatory obligations that municipalities strive to fulfill, and the spatial attachments that children and young people establish in their lived worlds. To this end, we introduce the concept of lived citizenship as an interface where the territorially-bound public administration and the plurality of spatial attachments characteristic to transnational living may meet. We conclude by proposing a re-grounding of lived citizenship in both topological and topographical terms as an improvement in theoretical understanding of mundane political agency and as a step towards more proficient participatory policies.  相似文献

Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research.  相似文献

The clinical forensic examinations conducted at the Institute of Legal Medicine of the Hanover Medical School between 1999 and 2008 in cases of suspected sexual abuse of children were evaluated retrospectively and analysed with regard to their legal outcome. In total, the study included 223 children (172 girls, 51 boys) with a median age of 8.6 years. In 34 children (15.2%), forensically relevant diagnostic findings due to anogenital injury and/or detection of semen were recorded. Perpetrators were convicted more often when they were not a member of the victim's family. In cases with victims aged seven years or older, conviction was more common. The study shows that medical findings can best be preserved by an immediate clinical forensic examination. Suspected sexual child abuse can often not be proved by medical examination results, but in some cases diagnostic findings are not mandatory for conviction.  相似文献

The presented case report describes the exclusion of the suspect of a sexual offence by means of methods of molecular genetics. Pretests for prostate-specific antigen performed at the beginning of the investigation and cytological sperm tests were negative. Nevertheless, by combining the methods of differential lysis and DNA quantification a small number of spermatozoa could be demonstrated in the trace evidence. Subsequently, the profile of the woman's boyfriend, with whom she had had unprotected vaginal intercourse two days before the incident, could be detected in the fraction of the hard lysis.  相似文献
