Size and Shape Differences in the Distal Femur and Proximal Tibia between Normal Weight and Obese American Whites 下载免费PDF全文
Katherine I. Harrington M.A. Daniel J. Wescott Ph.D. 《Journal of forensic sciences》2015,60(Z1):S32-S38
This study tests for differences in articular and diaphyseal size and shape of the distal femur and proximal tibia between normal weight and obese individuals, and discusses the effects of obesity on the patterns of sexual dimorphism and secular change in the skeletal morphology of the knee. Measurements of the femur and tibia were recorded for 143 American White adult males and females born in the 20th century. The sample was divided into normal and obese weight categories based on the body mass index. Results show differences between normal weight and obese individuals in the size and shape of the femoral shaft and the medial side of the knee joint, none of which affect the pattern of sexual dimorphism. While changes in skeletal morphology associated with obesity may be observed in recent secular changes, its role is still unclear because of the relatively recent increase in obesity prevalence. 相似文献

This article examines the applicability of the theory of multidimensional value space by Lynn A. Curtis and the theory of social cultural resistance—Afrocentrism by Daniel E. Georges-Abeyie for explaining so-called Black crime and Black juvenile delinquency in general and Black female crime and Black female juvenile delinquency in particular. It notes that the increase in so-called Black crime and Black juvenile delinquency in general and Black female crime and Black female juvenile delinquency in particular may be illusion, not fact. This article notes that perception, at times illusion, may have, and frequently does have, real outcomes, including criminal justice outcomes and delinquency outcomes. It notes that the so-called Black racial monolith is a fiction that race and ethnicity are distinct entities, as are sex and gender that the so-called Black racial monolith consists of distinct Black ethnic identities. The article notes that Black crime, female and male, and adult and juvenile delinquency may be manifestations of primary psychopathy, secondary psychopathy, and dyssocial psychopathy, as noted in the theory of social cultural resistance—Afrocentrism. 相似文献

Business "Not" as Usual: The National Incident Management System, Federalism, and Leadership 总被引:1,自引:0,他引:1
Federal, state, and local governments did not work well together to provide an effective response to Hurricane Katrina. Some of this failure can be attributed to the power struggle between the federal and state governments. The National Incident Management System (NIMS) was designed to foster collaboration among governments and their departments and agencies. However, this system largely failed. To overcome this failure, many have proposed centralizing disaster response in the federal government. Centralized control would damage the basic federal structure of our government as the national government appeals to the ever-present dangers of terrorism and natural disaster to gain permanent primacy in the relationship. The current federal system actually can work better than centralization if leadership and organizational transformation are stressed. The National Incident Management System has many elements in place that can make the federal system of disaster response work if the proper stress on organizational transformation and leadership is applied.

If we ignore the systemic issues and simply replace people or re-assign responsibilities, we may simply fail again in the not too distant future with a different cast of characters.

Just as the courts must consider the trade‐off between the best interest of the child and parental rights in involuntary termination of parental rights, policy on international adoption must consider the trade‐offs between the best interest of the child and the long‐term interests of the nation. We argue that countries that suspend international adoptions do not maximize social welfare. A consistent national policy to maximize the well‐being of the children and society at large would be to devote resources today to the oversight of international adoption in accord with child protections under the Hague Convention, while at the same time developing a domestic system of care that provides for the physical and developmental needs of orphaned children in the context of permanent families. 相似文献

This article is about how political regimes should generally be classified, and how Latin American regimes should be classified for the 1945–99 period. We make five general claims about regime classification. First, regime classification should rest on sound concepts and definitions. Second, it should be based on explicit and sensible coding and aggregation rules. Third, it necessarily involves some subjective judgments. Fourth, the debate about dichotomous versus continuous measures of democracy creates a false dilemma. Neither democratic theory, nor coding requirements, nor the reality underlying democratic practice compel either a dichotomous or a continuous approach in all cases. Fifth, dichotomous measures of democracy fail to capture intermediate regime types, obscuring variation that is essential for studying political regimes. This general discussion provides the grounding for our trichotomous ordinal scale, which codes regimes as democratic, semi-democratic or authoritarian in nineteen Latin American countries from 1945 to 1999. Our trichotomous classification achieves greater differentiation than dichotomous classifications and yet avoids the need for massive information that a very fine-grained measure would require. 相似文献
