Abstract: In the field of forensic footwear examination, it is a widely held belief that patterns of accidental marks found on footwear and footwear impressions possess a high degree of "uniqueness." This belief, however, has not been thoroughly studied in a numerical way using controlled experiments. As a result, this form of valuable physical evidence has been the subject of admissibility challenges. In this study, we apply statistical techniques used in facial pattern recognition, to a minimal set of information gleaned from accidental patterns. That is, in order to maximize the amount of potential similarity between patterns, we only use the coordinate locations of accidental marks (on the top portion of a footwear impression) to characterize the entire pattern. This allows us to numerically gauge how similar two patterns are to one another in a worst-case scenario, i.e., in the absence of a tremendous amount of information normally available to the footwear examiner such as accidental mark size and shape. The patterns were recorded from the top portion of the shoe soles (i.e., not the heel) of five shoe pairs. All shoes were the same make and model and all were worn by the same person for a period of 30 days. We found that in 20–30 dimensional principal component (PC) space (99.5% variance retained), patterns from the same shoe, even at different points in time, tended to cluster closer to each other than patterns from different shoes. Correct shoe identification rates using maximum likelihood linear classification analysis and the hold-one-out procedure ranged from 81% to 100%. Although low in variance, three-dimensional PC plots were made and generally corroborated the findings in the much higher dimensional PC-space. This study is intended to be a starting point for future research to build statistical models on the formation and evolution of accidental patterns. 相似文献

AbstractThe merits of being multi-lingual are widely recognised. This paper considers the application of this metaphor to the conceptualisation of clinical work in a women’s prison. We suggest that sharing ‘languages’ from different theoretical orientations in open fora enables teams to build deep and nuanced understandings of clinical and systemic complexity, of particular value in secure settings. This discussion reflects the service model developed and used within HMP/YOI Holloway, a large women’s prison in London, which has recently been closed. We utilise a case example, with formulations and recommendations from several perspectives, to illustrate the value of maintaining a rich, inclusive discourse. We describe the benefits of such an approach to staff teams, to institutions and to those we serve, and consider the implications for organisation of services to maximise potential for change and recovery. 相似文献

Some federal courts have used a reasonable woman standard rather than the traditional reasonable man or reasonable person standard to determine whether hostile environment sexual harassment has occurred. The current research examined the impact of the reasonable woman standard on federal district court decisions, controlling for other factors found to affect sexual harassment court decisions. Results indicated that there was a weak relationship between whether a case followed a reasonable woman precedent-setting case and the likelihood that the court decision favored the plaintiff. The implications of our findings for individuals and organizations involved in sexual harassment claims are discussed. 相似文献

Although a major predictor of sexual victimization is previous victimization, the mechanism underlying this effect is not well understood. Sexual assault history's impact on appraisal of and responses to sexual assault risk was examined in an experimental analog study. Intimacy with perpetrator was also examined as a potential contributor to appraisal and responses. Young women varying in sexual assault history were randomly assigned to receive a scenario in which type of perpetrator was manipulated (someone just met, friend, date, boyfriend). Respondents appraised the man's actions as sexual interest or assault and indicated intentions to respond (resistance and nonresistance). Sexual assault history did not directly influence appraisal or intended responses but had modest indirect effects on resistance via sexual assertiveness. The primary influence on appraisal and responses was perpetrator intimacy. Women facing advances within a more intimate relationship were less likely to appraise those advances as threatening and less likely to resist. 相似文献

Attending a university involves change and transition and an opportunity to study older adolescents’ attachment. The current study explored potential gender differences in both older adolescents’ need-and nonneed-based interactions with parents and their perceptions of attachment quality. Results indicated that although females did not initiate significantly more need-based contact with parents than males, they received significantly more need-based contact than males that was initiated by their parents. On the other hand, females both initiated and received nonneed-based contact with parents more than males. Consistent with attachment theory, parent–child need- and nonneed-based interactions were related to one’s perceived quality of attachment. Results indicated that adolescent attachment involves both need- and nonneed-based parent–adolescent interactions. The pattern of findings suggests that adolescent males and females may show attachment in different ways.This research is based on the first author’s master’s thesis at American University under the supervision of the second author.Department of Psychology, American University, Washington, DC.
