Forensic practitioners are recommended to dark adapt their eyes prior to conducting evidential searches in the dark. The dark adaptation process remains poorly standardised across the discipline, with little quantified regarding the benefits of such preparative steps. Herein, we report the findings of a study that recruited 50 participants to assess the effectiveness of the Crime-lite Eye?, a darkness adaptation device developed to assist forensic practitioners both in the laboratory and in field. Participants were tasked with searching for the fluorescent signatures left by reaction of 1,8-diazafluoren-9-one (DFO) with amino acids, in a manner akin to the fluorogenic fingerprint treatment of porous evidence. Using an Epson Stylus Photo R265 inkjet printer, ink cartridges were filled with alanine solutions of various concentrations, allowing different motifs to be printed onto copy paper and subsequently developed using DFO. Participants searched for this ‘evidence’ both with and without dark adapted vision. On average, participants were able to locate and correctly recognise 16% more evidence once dark adapted using the Crime-lite Eye?.The increase in evidence located by participants once dark adapted suggests that crime scene officers should be dark adapting in order to visualise as much as possible. The time taken to dark adapt, 10?min on average during this study, is not excessively long, and should not significantly slow the investigation. 相似文献
Reports of identity theft in the U.S. have risen since the 2000s, which has resulted in financial losses into the billions. Along with this rise is the increased likelihood of familial identity theft. In this study, the differences between familial and non-familial identity theft were explored through the January–July 2012 Identity Theft Supplement collected with the National Crime Victimization Survey. Results showed that family member victims were likely to have experienced one type of identity theft more often than non-family victims were, personal information used for other fraudulent purposes, which included government benefits and driver’s licenses. Factors that allowed for a respondent’s personal information used for other fraudulent purposes included family membership, young persons in the household, and repeat victimization. Findings suggest that few factors can predict the likelihood to experience the misuse of personal information and that familial identity theft may be difficult to detect. 相似文献
An international project called PADS promoted participatory learning and action research with inland valley rainfed rice farmers in West Africa. All countries received the same training, similar funding, and the same leadership. Although the staff in Ghana were conscientious and gave much training to the farmer beneficiaries, the Mali staff explicitly encouraged farmers to experiment. Farmers in Mali responded to this favourable attitude by experimenting more than those in Ghana, and in qualitatively more interesting ways. Long-term engagement with grassroots organisations may be as conducive to changing public servants' attitudes as the actual participatory approach promoted on the ground.
L'attitude compte: travail avec des riziculteurs en Afrique de l'Ouest
Un projet international appelé PADS a favorisé l'apprentissage participatif et la recherche-action avec des riziculteurs pratiquant la culture pluviale dans les vallées de l'intérieur des terres en Afrique de l'Ouest. Tous les pays ont reçu la même formation, un financement similaire et le même leadership. Alors que les membres du personnel du Ghana étaient consciencieux et dispensaient une formation considérable aux agriculteurs bénéficiaires, le personnel du Mali encourageait expressément les riziculteurs à faire des expériences. Les riziculteurs du mali ont réagi à cette attitude favorable en faisant plus d'expériences que ceux du Ghana, et ce de manières plus intéressantes sur le plan qualitatif. L'engagement à long terme avec les organisations de la base populaire peut être tout aussi propice à la modification des attitudes des fonctionnaires que l'approche participative même promue sur le terrain.
As atitudes contam: Engajamento com produtores de arroz na África Ocidental
Um projeto internacional chamado PADS promoveu uma pesquisa sobre aprendizado e ação participativa com produtores de arroz irrigado com água da chuva no interior do vale na África Ocidental. Todos os países receberam o mesmo treinamento, financiamento semelhante e a mesma liderança. Embora os funcionários de Gana estivessem cientes e oferecessem bastante treinamento aos produtores beneficiários, os funcionários de Mali incentivaram explicitamente os produtores a experimentar. Os produtores de Mali responderam a esta atitude favorável experimentando mais do que aqueles de Gana e de maneiras mais interessantes em termos qualitativos. O engajamento de longo prazo com organizações de base pode contribuir para mudar as atitudes dos servidores públicos tanto quanto a abordagem participativa real promovida na base.
La actitud cuenta: el trato personal con campesinos arroceros de África Occidental
Un proyecto internacional llamado PADS promovió el aprendizaje participativo y la investigación-acción entre campesinos que cultivaban arroz de secano en los valles centrales de África Occidental. Todos los países participantes recibieron la misma capacitación, un financiamiento similar y las mismas orientaciones. Si bien el personal de Ghana era muy diligente y transmitió muchos conocimientos a los campesinos beneficiarios en capacitaciones, el personal de Malí se centró más explícitamente en animarlos para que experimentaran. Los campesinos de Malí respondieron a esta actitud estimuladora realizando más experimentos y de maneras cualitativamente más interesantes que los campesinos de Ghana. El compromiso de largo plazo con organizaciones de base puede ser tan importante para lograr un cambio en la actitud del servidor público como el método participativo que se promueve en la actualidad sobre el terreno. 相似文献
Knowing where criminal justice-involved teens look for support and whether those supports reduce depression has important and possibly gender-specific treatment implications for this vulnerable population. This study examines the relationships between social support and depression in a mixed-gender sample of 198 incarcerated adolescents. Greater support from families and overall and greater satisfaction with supports predicted lower depression for boys and girls. Support from siblings and extended family strongly predicted lower depression; support from parents and from friends was either not related or only weakly related to depression. Girls reported higher levels of depression, more support from friends and extended family, and less support from parents than did boys. Family, sibling, and overall support were stronger predictors of depression for girls than for boys. Results suggest that nonparent family members, especially siblings and extended family, provide important emotional resources for teens in the criminal justice system. 相似文献
Methods to estimate adult age from observations of skeletal elements are not very accurate and motivate the development of better methods. In this article, we test recently published method based on the acetabulum and Bayesian inference, developed using Coimbra collection (Portugal). In this study, to evaluate its utility in other populations, this methodology was applied to 394 specimens from four different documented Western European collections. Four strategies of analysis to estimate age were outlined: (a) each series separately; (b) on Lisbon collection, taken as a reference Coimbra collection; (c) on Barcelona collection, taken as a reference both Portuguese collections; and (d) on London collection taken as reference the three Iberian collections combined. Results indicate that estimates are accurate (83-100%). As might be expected, the least accurate estimates were obtained when the most distant collection was used as a reference. Observations of the fused acetabulum can be used to make accurate estimates of age for adults of any age, with less accurate estimates when a more distant reference collection is used. 相似文献
The purpose of this study was to examine the influence of religious dissimilarity and religious personal identity on one’s
job satisfaction. Data were collected from 260 top managers. Structural equation modeling indicated that religious dissimilarity
positively affected perceived value dissimilarity from others, which in turn, held a negative association with job satisfaction.
These effects were qualified, however, by a significant religious dissimilarity × religious personal identity interaction
such that, for persons whose religious beliefs were a central part of who they were, being religiously different from others
in the workplace strongly impacted their perceived value dissimilarity. Research contributions and practical implications
are discussed. 相似文献
We present evidence on industry productivity growth and business dynamics in Dutch industries for the period 2007–2012, and investigate whether there is a role for ICT intensity in explaining differences across industries. Moreover, we relate ICT intensity to various distributional characteristics of firm performance, such as the dispersion of labor productivity and turnover, concentration and turbulence of market shares, and the efficiency of resource allocation. In the first part of the paper we follow a decomposition approach, whereas in the second part we apply a regression based analysis. The results suggest that productivity growth is higher in ICT production and industries with high ICT usage, but that ICT also increases differences in firm performance and leads to concentration of markets. In addition, there is evidence that markets are more efficient in ICT intensive industries. 相似文献
