Frontal sinuses (FSs) have been studied in radiology, anthropology, and forensic anthropology. This study aimed to determine whether it was possible to predict the age and sex of an individual using FS volume. Sixty‐nine anonymized CT scans were imported to MIMICS 10.01® software (Materialise N.V.), and each FS volume was calculated in mm3. There was an absence of significant difference between right and left FS volume (p = 0.173) and an absence of correlation between age and FS volume (Pearson's test; p = 0.705). Sexual dimorphism was significantly different (p = 0.001). However, the most discriminant datum for determining sex was found to be the total FS volume (sum of an individual's right and left FS volumes) with linear discriminant Fisher's function coefficients of ?2.759 for the male group and ?1.275 for the female group. With this model, 72.5% of our sample was correctly classified according to sex. 相似文献

The Analysis of Colored Acrylic,Cotton, and Wool Textile Fibers Using Micro‐Raman Spectroscopy. Part 2: Comparison with the Traditional Methods of Fiber Examination 下载免费PDF全文
In the second part of this survey, the ability of micro‐Raman spectroscopy to discriminate 180 fiber samples of blue, black, and red cottons, wools, and acrylics was compared to that gathered with the traditional methods for the examination of textile fibers in a forensic context (including light microscopy methods, UV‐vis microspectrophotometry and thin‐layer chromatography). This study shows that the Raman technique plays a complementary and useful role to obtain further discriminations after the application of light microscopy methods and UV‐vis microspectrophotometry and assure the nondestructive nature of the analytical sequence. These additional discriminations were observed despite the lower discriminating powers of Raman data considered individually, compared to those of light microscopy and UV‐vis MSP. This study also confirms that an instrument equipped with several laser lines is necessary for an efficient use as applied to the examination of textile fibers in a forensic setting. 相似文献

This article provides a response to Prof. Thomson's critique, noting many points of agreement and also the broader consensus that is emerging among experts in the field. The research evidence, and the wider body of knowledge on children's well‐being generally, supports the proposition that relocation is a risk factor for children after parental separation but provides no support for a general presumption either in favor of, nor against, relocation. Nor should it be assumed that the interests of children are the same as those of their primary caregiver. We defend our three questions arguing the need in an adult‐centric debate to focus resolutely on children's interests rather than on adult rights. Both Prof. Thompson's approach and our own involve guided decision making with the child's best interests as the paramount consideration—his through weak presumptions based upon research about how judges respond to relocation issues and ours through focused questions based on research on how parents and children respond to relocations issues. We do not consider that codifying the existing practices of the courts represents real reform. We identify various risks involved in using presumptions, but note that, in jurisdictions with limited publicly funded resources for individual case assessment, presumptions, burdens or guidelines may be needed to offer rough justice to impecunious parents.
- Key Points for the Family Court Community
- Notes points of emerging agreement on relocation within the research community
- Explores the differences between the use of presumptions and focused questions and highlights the role of empirical research of the lived experience of children and families postrelocation disputes
- Identifies how the level of public resourcing for the family law system may impact upon decisions about the substance of the law concerning relocation

Labouring in the Shadow of the British Political Tradition: The Dilemma of ‘One Nation’ Politics in an Age of Disunification 下载免费PDF全文
The British state is in flux and the Labour party is struggling to shape an effective response to the politics of disunification. This article reflects on the nature of Labour's governing project and its conception of modern statecraft which has evolved since the party became a serious contender for power in the aftermath of the First World War. We argue that Labour's initially pluralising instincts cultivated in opposition have been checked by the ongoing reality of a state‐centric mode of governing, in which the party continued to robustly defend the Westminster model operating within the parameters established by the British Political Tradition (BPT). Ed Miliband's conception of ‘One Nation’ Labour threatens to reinforce this historical pattern of reversion to the Westminster model, at precisely the moment when devolutionary forces are destabilising the existing political settlement. To break out of this impasse, Labour must look elsewhere in its ideological lexicon for inspiration, chiefly to the tradition of socialist pluralism and associationalism. 相似文献

Abstract In his thoughtful analysis, Joseph realistically points to what a mixed‐income housing development can and cannot offer its low‐income residents. Observed benefits include greater informal social controls over the development, likely proximal modeling opportunities for youth, and participation in a political‐economic subgroup that can demand more responsive public services. Yet without offering more comprehensive, structured supports to its residents, no form of housing alone can be an antidote to poverty. However, if we expand Joseph's analysis to include the impact of large‐scale developments on distressed urban neighborhoods, we can see mixed‐income housing catalyzing other benefits for low‐income residents. These benefits include a reduced housing cost burden; more structured supportive services; dramatically improved surroundings; high‐quality housing and community design; faster‐paced complementary investments in public systems and amenities; and strategically restored market functioning that offers more choices, lower prices, new jobs, and additional tax revenues to support service delivery. 相似文献

The Family Unification Program—a U.S. Department of Housing and Urban Development initiative to facilitate interagency collaboration between the child welfare and public housing service systems—aims to stabilize families at risk for parent–child separation by addressing housing needs. Findings from a randomized controlled trial suggest that families referred to the program experienced lower risk for homelessness and out-of-home placement compared with child welfare services as usual. The findings suggest that housing services offer an effective alternative to foster care. 相似文献

We investigate the characteristics of the owners of small businesses that participate in the informal sector of an emerging economy and their perception of the risk of detection by tax authorities while doing so. Data are gathered from a survey covering 1027 small businesses in Trinidad and Tobago. Results suggest that small business owners are motivated to participate in the informal sector when they believe that the risk of detection by the tax authorities is low and that government regulations are burdensome, but there is no evidence that the tax rate itself is an issue. Their perception of the risk of detection by the tax authority is determined largely by the time they spend and the income they earn in the formal sector. 相似文献

Many local governments have now endured a decade of fiscal decline due to periodic reductions in external funding (federal and state and slowdowns in the rate of growth of the state and local government sector. This research examines the extent to which six large jurisdictions (three cities, three counties) under fiscal duress avoided political conflict and prevented further fragmentation of their authority between 1978 and 1987. The results showed that local officials generally chose retrenchment strategies (revenue, expenditure, and borrowing) with the least anticipated political opposition; but where hard choices had to be made (personnel reductions), they were made without hesitation. The timing of politically unpopular choices to coincide with downward trends in the private sector reduced the level of political fallout, even in heavily unionized, socioeconomically diverse communities. The results also showed that local officials strongly endorsed, rather than opposed, strategies that further fragmented their authority (privatization, intergovernmental cooperative agreements), because these approaches produce significant personnel and capital savings in the short term. Finally, the results indicated that the long-term cumulative effects of short-term decremental decisionmaking on the quality of life (as measured by drops in bond ratings) were negative in only one-third of the jurisdictions. 相似文献

Suicide is generally regarded as an anti-social behavior. It is, perhaps, for this reason that sociologists and psychologists, among other experts, have been interested in studying the incidence of suicide in many societies. Most modern theories on suicide, however, do not emphasize the idea of “heroic suicide.” Epitomizing this “genre” of suicide are the high profile, politically motivated suicides in early colonial Ibadan examined here. This article suggests that the key to understanding these suicide cases is to be found not only in these people’s multilayered pasts — the general Yoruba past and Ibadan’s nineteenth-century military heritage — but also in their conception of honor and in their social norms. The ideals of honor thus carried over into the twentieth century were so strong that they survived the first three decades of colonial rule despite the intrigue-laced nature of Ibadan chieftaincy politics and the official interference of the colonial authorities. This article concludes that politically motivated suicide, though self destructive was actually meant to serve an honorable purpose such that those involved became heroes even in death. There is therefore the need for suicide theorists to highlight exceptions like these. 相似文献
