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

Footwear examination can provide an important link between the crime scene and the suspect. Casts have been taken from snow, soil, and sand substrates to assist with the examination and to accurately depict the impression. However, there has been some discrepancy on what kind of fixative, if any, should be used with impressions present in sand. This study tested four different fixatives on three sandy substrates. Eight gross characteristics were added to a boot sole, and thirty sand impressions were created in each substrate. Except for one control set that remained untreated, the impressions were treated with a fixative agent before casting. The ninety shoe casts were examined by a qualified footwear examiner and scored based on his ability to see the eight characteristics. The results indicated that pump‐action hairspray was the most successful on play and construction sand, while beach sand impressions without any fixative scored highest.  相似文献

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

To determine if changes in fingerprint infrared spectra linear with age can be found, partial least squares (PLS1) regression of 155 fingerprint infrared spectra against the person's age was constructed. The regression produced a linear model of age as a function of spectrum with a root mean square error of calibration of less than 4 years, showing an inflection at about 25 years of age. The spectral ranges emphasized by the regression do not correspond to the highest concentration constituents of the fingerprints. Separate linear regression models for old and young people can be constructed with even more statistical rigor. The success of the regression demonstrates that a combination of constituents can be found that changes linearly with age, with a significant shift around puberty.  相似文献

ABSTRACT

Can we pave the way to world peace through education of the next generation? This paper focuses on how teaching social and emotional learning (SEL) skills in schools could promote the positive development of children and youth so that they can choose prosocial, nonviolent ways of building relationships with others. First, research on how belonging and fairness develop early in life is briefly reviewed. Then the authors introduce SEL and the research supporting its impact, and explain how it can be supported through various strategies in the classroom, including programs, teacher–student relationships, cooperative learning, approaches to discipline, and solving problems and dealing with conflict peacefully. Building peace by promoting social and emotional development through education offers hope for future generations.  相似文献

Abstract

Child services organisations need policies that minimise the risk of sexual abuse of the children in their care. In particular, managers (and the public) are justifiably concerned when abuse is perpetrated by individuals who should not have been working with children in the first place. Unfortunately, there has been relatively little work on determining unacceptable risk for sexually abusive behaviour in child service organisations. The purpose of this paper is to describe the contexts in which screening procedures are appropriate, review the academic literature on screening procedures and present the results of a pilot survey of current screening practices in the United Kingdom. We comment on the effectiveness of screening measures available for use by organisations and provide suggestions for improvement. Specifically, we recommend that screening procedures consider risk factors associated with the onset and persistence of child sexual abuse perpetration.  相似文献

Abstract

Assessing the implicit attitudes and beliefs of offenders has proved difficult over decades of work and research with offender samples. The purpose of this paper is to outline the research related to the use of the emotional Stroop task and to encourage researchers and practitioners to use it as a measure to assess the implicit attitudes of offenders within their assessments. We consider the factors that may influence Stroop results along with the research considerations that need to be taken into account when using an emotional Stroop paradigm. Currently, a significant limitation of the emotional Stroop task is a lack of standard word stimulus sets that are able to distinguish between offender types. This limitation could seriously impede further development of this tool. Suggestions for future research are proposed.  相似文献

Bhaduri, Rahman and Arn's article on the persistence of small farms in the April 1986 issue of The Journal of Peasant Studies is reviewed. The article raises a number of critical points for understanding the effects of capitalist penetration of land‐holding patterns in Bangladesh. It is argued that the discussion would benefit from a refined methodological and definitional focus to avoid misrepresenting processes of polarisation. Particular attention in this review is given to a critique of the construction of the land stability ratio and to the conceptualisation and definition of the term ‘small farm’.  相似文献
