Using micro-X-ray fluorescence (MXRF), a novel means of detecting fingerprints was examined in which the prints were imaged based on their elemental composition. MXRF is a nondestructive technique. Although this method requires a priori knowledge about the approximate location of a print, it offers a new and complementary means for detecting fingerprints that are also left pristine for further analysis (including potential DNA extraction) or archiving purposes. Sebaceous fingerprints and those made after perspiring were detected based on elements such as potassium and chlorine present in the print residue. Unique prints were also detected including those containing lotion, saliva, banana, or sunscreen. This proof-of-concept study demonstrates the potential for visualizing fingerprints by MXRF on surfaces that can be problematic using current methods. 相似文献

Historically, fatal injury monitoring and surveillance have relied on mortality data derived from death certificates (DC). However, problems associated with utilizing DC have been well documented. Recently, access to and utilization of hospital discharge data (HDD) have offered a new and important secondary source of data regarding in-hospital deaths. However, studies have shown that discrepancies between the HDD and the corresponding DC often exist. This discrepancy was especially evident when comparing HDD to the vital statistics data (VSD) for deaths by falls among those aged 65 and over in 19 states.This was a retrospective forensic review of elderly (age 65 and over) fall-associated fatalities (E880-E888) identified from HDD and VSD in Allegheny County, Pennsylvania, between 1997 and 1998. Seventy-seven cases were identified, with the original manner of death listed as natural (34), suicide (1), and accidental (42) on the DC. Following a forensic review of the cases, the manner of the death on the DC should have been changed from natural to accidental in 28% (n = 12) of the cases, representing an undercount in the VSD. Undercounts were due to a failure of clinicians to account for the significance of a fall event that contributed to subsequent pathology and death. In addition, in that 22% (n = 17) of the HDD fall-associated deaths, the fall did not contribute directly or sequentially to the underlying cause of death, thereby representing an overcount in the HDD.Based on these findings we recommend (1) elderly fall surveillance systems should only count HDD E-coded falls that demonstrate a serious traumatic injury which directly or subsequently results in death, (2) all in-hospital fall-associated deaths should be reported to and reviewed by coroner/Medical Examiner offices for determination of the cause and manner of death, and (3) physicians should be better educated in properly completing death certificates. 相似文献

Community capacity for organization and collaboration has been shown to be a powerful tool for improving the health and well-being of communities. Since 1994 the Washington State Family Policy Council has supported the development of community capacity in 42 community public health and safety networks. Community networks bring local communities together to restructure natural supports and local resources to meet the needs of families and children, and increase cross-system coordination and flexible funding streams to improve local services and policy. In this study, researchers sought to demonstrate the strong impact of the community networks' capacity to interrupt health and social problems. Findings suggest that community networks reduce health and safety problems for the entire community population. Further, community networks with high community capacity reduced adverse childhood experiences (ACE) in young adults ages 18-34. 相似文献

Sexual misconduct has emerged as a widespread problem throughout the criminal justice system as indicated by law enforcement officer sexual assault incidents in various cities and the findings of the recent National Prison Rape Elimination Act Research Commission. Through multivariate statistical analysis of data from two Department of Defense-wide surveys (2002 and 2006), this paper examines the indicators and cofounders of sexism, sexual harassment, and sexual assault with attention to change during the study period. Findings inform a suggested anticipatory model for prevention and intervention in military settings that, based on shared characteristics such as male dominance and authoritarian culture, provide an approximate reference context for criminal justice sexual misconduct best practices consideration. 相似文献

Parole board members (PBMs) decide whether to release inmates on parole. Decisions may be affected by in‐group bias or stereotypes regarding religion and race. Two experiments investigated whether religious conversions/secular lifestyle changes and race affect mock PBMs' release decisions, emotions, and perceptions. Mock PBMs read a case file of an inmate who was eligible for parole and decided whether to grant parole. Study 1 manipulated whether the inmate had converted to Christianity or Islam, had a secular lifestyle change, or had no lifestyle change. Study 2 also varied race (African American or Caucasian). Race was not a significant factor, possibly because the manipulation was not strong enough to influence participants or because participants did not want to appear racist. Conversions to Islam and Christianity impacted the parole decision, and effects were mediated by believability of the conversion. Secular lifestyle changes affected release decisions and were mediated by perceptions of the inmate and beliefs about his likelihood of recidivism. Such inmates were the most likely to be released and were perceived most positively; their conversions were the most believable. Inmates who made no changes were perceived least positively, indicating that any lifestyle change is better than none. Importantly, no bias towards either religion (Islam, Christianity) was found. Furthermore, conversion type affected how scared PBMs were of the inmate, but this fear did not impact release decisions. 相似文献

For most states the methodology used for assigning Unemployment Insurance tax rates to employers arose when the program was first established in 1935. More than 80 years later, with evolving employment relationships, state systems have become outmoded. This paper critiques current experience rating methods and presents new methodologies that are much easier to operate and that improve the incentives for employers to increase employment. The proposed methods would assess taxes based on employment or payroll variation such that growing firms would have lower taxes. A simulation analysis illustrates the impact of the new methods on employer groups. 相似文献
