The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.  相似文献

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

A review of the literature was conducted to assess the extent and nature of the practice of requiring parents to transfer custody in order to receive public funding for intensive services needed by their child/adolescent who had a serious emotional disorder. The review focused on the legal and policy basis of this practice as well as its social and psychological impact on child and family. We conclude that the practice of transfer of custody as a requirement for receiving financial aid occurs in a majority of states, though the actual extent of this practice is not known. The major factor influencing the use of transfer of custody appears to be the absence of an appropriate and adequate system of services for children and adolescents with serious emotional disorders. We recommend that the practice of requiring custody transfer for the sole purpose of receiving services be abolished and offer several suggestions for improving acess to services.Preparation of this article was supported in part by the National Institute of Mental Health (NIMH) under contract no. 89MF761903. The authors are grateful to John Burke and Kelly Kelleher of the Division of Biometry and Applied Sciences, NIMH for their assistance on this project. Laurie Flynn, Executive Director for the National Alliance for the Mentally Ill, was very helpful during the informative stage of the project. Barbara Friesen, Director of the Research and Training Center at Portland State University, gave us useful guidance throughout the project. We thank Stephen Hill, Consultant to the National Governors' Association, for his help. We are grateful to Amy Hewitt and Carol Ishler for their assistance in preparing this report. We also would like to acknowledge several individuals who assisted us with research reported in this article. We are grateful to Governor Richard F. Celeste of Ohio for his letter of support for the state survey of custody transfer practices. We appreciate the efforts on behalf of this survey by staff from the State of Ohio, particularly Jean Ellen Stevens, Administrative Assistant to the Director of the Department of Mental Health. Margraret McNally assisted in the compilation of data for both surveys.  相似文献

劳动力市场人才资源的配置问题是小城镇服务业发展中急需解决的重要问题之一。本文从用人单位满意度分析的基础上,采用模糊综合评价法对当前小城镇服务业劳动力需求与人才培养对接问题现状进行了评价,发现劳动力市场人才资源的配置与人才培养供给之间出现了严重的失衡。人才培养只有遵循劳动力市场需求,动态地调整培训方案与体系,才能够健康持续地发展。  相似文献
