A new technique for three-dimensional ultrasound scanning of facial tissues   总被引:1,自引:0,他引:1  
We report the development of an ultrasonic facial scanning technique that allows for the visualization of continuous contours without deforming surface tissues. Adhesive markers are placed on the face to enable measurement of facial tissue thicknesses at specific landmarks. The subject immerses the face in a clear plastic box filled with water for about 20 seconds while the researcher moves the transducer along the bottom of the box, guiding transducer movement by watching the facial image in a mirror placed below. 3D Echotech software (1) builds the images from sequentially acquired 2D frames. Reliability of repeat measurements at landmarks is good, and individual tissues (skin, subcutaneous, muscle) can be distinguished. The method is simple, reliable, less expensive and less time consuming than alternatives such as magnetic resonance imaging (MRI). It is applicable in both research and clinical contexts.  相似文献

This paper describes medical research pertaining to the future potential for genetic engineering of human embryos, and considers some of the consequences that this technology may have for women's lives. It points to both the religious right and the medical profession as groups that could potentially benefit from human genetic engineering and emphasizes the need for feminists to monitor and respond to emerging reproductive technologies.  相似文献

This article examines the present discourse of conflict resolution and offers an alternative framework for analyzing the generic sources of conflict at the community, state, and interstate levels. In particular, we argue that although peace is a universal value, there are no universally best strategies to achieve it. This, however, does not mean that the path to peace is fundamentally different in every context. We claim that stable democratic political structures in general lead to peace both in the international and the domestic realms. As such, democratization does lead to peace, but the paths to stable democracy are context sensitive. Therefore, the success of efforts aimed at creating long-term peace, both among and within nations, depends on the extent to which, democratization incorporates the norms and values of the societies in question. The article begins with a brief overview of some of the problems associated with defining peace. We suggest that peace should be looked at as a universal value, as democracy has been in the recent past. We provide a more detailed theoretical assessment of the linkage between democracy and peace. Our general argument is illustrated in the South Asian, specifically the Indian, context.  相似文献

Does context—racial, economic, fiscal, and political—affect whites’ votes on racially-related ballot propositions? We examine non-Hispanic whites’ voting behavior on three California ballot initiatives: Propositions 187, 209, and 227. Unlike previous analyses that lacked individual-level data and were therefore limited to ecological inference, we combine individual-level data from exit polls with county-level contextual variables in a hierarchical linear model. Racial/ethnic context affected whites’ votes only on Proposition 187, economic context had no influence on vote choice, and the effect of fiscal context was limited to Proposition 227. However, across the propositions, whites’ decisions were shaped by their political context. Thus, we do not find support for the “racial threat” hypothesis across all racially-charged issues.  相似文献

This study of cadets at the United States Air Force Academy during their first six months assessed the pattern of developmental changes in occupational identity status for males and females, examined the relationship of internal-external control to identity statuses, and discussed the data in terms of Erikson's proposals and factors involved in gender differences in identity development. More than half of the cadets entering the academy were in uncommitted occupational identity statuses. Over the time period, half the cadets remained in their identity statuses, with the Foreclosed cadets the most stable and Achieved the least stable. The expected changes in the Achieved identity status, and other changes, established a pattern of identity development congruent with Erikson's theory of developmental progress or regression in identity formation. Only male cadets demonstrated significant changes into or out of a status, and significant associations between their identity statuses and internal-external control, with more internally controlled males being Achieved and more externally controlled males being Diffused-diffused.The views expresed in this article are the author's and do not necessarily reflect those of the United States Air Force or the United States Air Force Academy, Colorado Springs, Colorado.Received Ph.D. from State University of New York at Buffalo.

A conceptual model derived from attachment theory was tested by examining adult attachment style, cognitive distortions, and both general and victim empathy in a sample of 61 paroled child molesters and 51 community controls. Results of logistic multiple regression showed that attachment anxiety, cognitive distortions, high general empathy but low victim empathy significantly increased the odds of child molester status. Findings supported theoretically based hypotheses, suggesting that attachment theory may be useful in the conceptualization and treatment of child molesters.  相似文献
