A methodology to estimate the time of latent fingerprint deposition would be of great value to law enforcement and courts. It has been observed that ridge topography changes as latent prints age, including the widths of ridges that could be measured as a function of time. Crime suspects are commonly identified using fingerprint databases that contain reference inked tenprints (flat and rolled impressions). These can be of interest in aging studies as they provide baseline information relating to the original (nonaged) ridges’ widths. In practice, the age of latent fingerprints could be estimated following a comparison process between the evidentiary aged print and the corresponding reference inked print. The present article explores possible correlations between inked and fresh latent fingerprints deposited on different substrates and visualized with TiO2. The results indicate that the ridge width of flat inked prints is most similar to fresh latent fingerprints, and these should be used as the comparison standard for future aging studies.  相似文献

Although researchers have made numerous advances in the understanding of the nature, extent, and dynamics of violence against women (VAW), there is an ever-increasing need for data used in academic research and within policy decision-making to be collected via rigorous methodological designs to accurately measure the incidence and impact of VAW. What is now needed are research collaborations within an interdisciplinary research cluster that will expand understanding of the complex nature of VAW. The current article details an agenda or “call to action” to address deficiencies and advance VAW research, in addition to informing VAW intervention and prevention efforts.  相似文献

Over the past three decades, open licensing has evolved from hacker culture thought experiment to a transformative force in applied copyright across a range of industries. Yet very little empirical research exists to understand its disparate uses. This article examines social practices and attitudes about open licensing in order to examine the practical experience of creators and consumers who use this tool and in order to assess its value in moderating the negative consequences of extensive copyright. The discussion about the role of open licensing in creative industries and communities tends to be polarized into two vantage points. Either (1) it is a new, altruistic paradigm enabling creative communities to rework copyright to fit their vision for the cultural commons, or (2) it is a radical theft of creative labor, encouraged by Google and other digital industrial powerhouses, to cheat creators out of their share of profits. Both of these rhetorical vantage points presume a monolithic and largely either selfless or unaware base of creative laborers. We analyze data from a series of surveys across a range of creative fields and practices to show that creators employ open licensing for a variety of reasons, including instrumental purposes oriented toward skirting the many impediments created by institutions and law, rather than merely because they are unaware or selfless.  相似文献

This study used a mixed-methods approach to investigate stigma experiences and self-concepts of individuals with both mental illness and criminal histories. The full sample of participants completed self-report measures of self-concept related to mental illness, race, and criminal history, and a brief qualitative self-concept measure. A subsample of participants completed semi-structured interviews, which were analyzed for content domains. Analyses suggested that several aspects of self-concept related to responses on stigma measures. Participants who identified their own styles of acting, feeling, and thinking tended to exhibit less mental illness self-stigma. Qualitative interview findings suggested that the majority of participants described stigma experiences related to mental illness, race, and criminal history, and these stigmatized identities negatively influenced one another. Conclusions review how stigmatized identities can intersect in powerful ways for individuals with mental illness and histories of criminal offending, and discuss implications for future research and clinical practice.  相似文献

Health impact assessment (HIA) has been advanced as a means of bringing potential health impacts to the attention of policy makers, particularly in sectors where health impacts may not otherwise be considered. This article examines lessons for HIA in the United States from the related and relatively well-developed field of environmental impact assessment (EIA). We reviewed the EIA literature and conducted twenty phone interviews with EIA professionals. Successes of EIA cited by respondents included integration of environmental goals into decision making, improved planning, and greater transparency and public involvement. Reported shortcomings included the length and complexity of EIA documents, limited and adversarial public participation, and an emphasis on procedure over substance. Presently, EIAs consider few, if any, health outcomes. Respondents differed on the prospects for HIA. Most agreed that HIA could contribute to EIA in several areas, including assessment of cumulative impacts and impacts to environmental justice. Reasons given for not incorporating HIA into EIA were uncertainties about interpreting estimated health impacts, that EIA documents would become even longer and more complicated, and that HIA would gain little from the procedural and legal emphasis in EIA. We conclude that for HIA to advance, whether as part of or separate from EIA, well-formulated methodologies need to be developed and tested in real-world situations. When possible, HIA should build on the methods that have been utilized successfully in EIA. The most fruitful avenue is demonstration projects that test, refine, and demonstrate different methods and models to maximize their utility and acceptance.  相似文献

This study employs classification tree analysis (CTA) to address whether 3 groups of violent offenders have similar or different risk factors for violent recidivism while on probation. A sample of 1344 violent offenders on probation was classified as generalized aggressors (N = 302), family only aggressors (N = 321), or nonfamily only aggressors (N = 717). The strongest predictor of violent recidivism while on probation was whether the offender was a generalized aggressor or not, with generalized aggressors more likely to be arrested for new violent crimes. Prior arrests for violent crimes predicted violent recidivism of generalized aggressors, but did not significantly predict violent recidivism of family only and nonfamily only aggressors. For generalized aggressors and family only batterers, treatment noncompliance was an important risk predictor of violent recidivism. CTA compared to logistic regression classified a higher percentage of cases into low-risk and high-risk groups, provided higher improvement in classification accuracy of violent recidivists beyond chance performance, and provided a better balance of false positives and false negatives. The implications for the risk assessment and domestic violence literature are discussed.  相似文献

We present a validated method for the simultaneous analysis of basic drugs which comprises a sample clean-up step, using mixed-mode solid-phase extraction (SPE), followed by LC–MS/MS analysis. Deuterated analogues for all of the analytes of interest were used for quantitation. The applied HPLC gradient ensured the elution of all the drugs examined within 14 min and produced chromatographic peaks of acceptable symmetry. Selectivity of the method was achieved by a combination of retention time, and two precursor-product ion transitions for the non-deuterated analogues. Oral fluid was collected with the Intercept®, a FDA approved sampling device that is used on a large scale in the US for workplace drug testing. However, this collection system contains some ingredients (stabilizers and preservatives) that can cause substantial interferences, e.g. ion suppression or enhancement during LC–MS/MS analysis, in the absence of suitable sample pre-treatment. The use of the SPE was demonstrated to be highly effective and led to significant decreases in the interferences. Extraction was found to be both reproducible and efficient with recoveries >76% for all of the analytes. Furthermore, the processed samples were demonstrated to be stable for 48 h, except for cocaine and benzoylecgonine, where a slight negative trend was observed, but did not compromise the quantitation. In all cases the method was linear over the range investigated (2–200 μg/L) with an excellent intra-assay and inter-assay precision (coefficients of variation <10% in most cases) for QC samples spiked at a concentration of 4, 12 and 100 μg/L. Limits of quantitation were estimated to be at 2 μg/L with limits of detection ranging from 0.2 to 0.5 μg/L, which meets the requirements of SAMHSA for oral fluid testing in the workplace. The method was subsequently applied to the analysis of Intercept® samples collected at the roadside by the police, and to determine MDMA and MDA levels in oral fluid samples from a controlled study.  相似文献

It has frequently been remarked that it seems to have been reserved to the people of this country, by their conduct and example, to decide the important question, whether societies of men are really capable or not of establishing good government from reflection and choice, or whether they are forever destined to depend for their political constitutions on accident and force.  相似文献

This article argues that the World Trade Organization (WTO)jurisprudence on the allocation of the burden of proof is ina confused state. Panels and the Appellate Body have failedto produce a consistent line of cases, which can be used asa predictable model to solve future cases. Furthermore, thejurisprudence has also created artificial differences betweensimilar provisions, raising questions about the relevance ofthe criteria employed to distinguish provisions that must beproved by the defendant from those that must be proved by thecomplainant. The analysis undertaken in this article suggeststhat it may be time to reflect upon the basic question of whythe burden of proof should be allocated to a given party. Thearticle explores alternatives and suggests courses of action.  相似文献

A collaborative research process engaging Alaska Native communities in the study of protective factors in Alaska Native sobriety and the design of a preventative intervention using its findings is described. Study 1 was discovery oriented qualitative research whose objectives were identification of protective factors and development of a heuristic model. Study 2 involved quantitative survey methods to develop and test ameasure of protective factors identified by the qualitative study. Empirical data from these studies is presented, and the role of Alaska Native co-researchers who did not possess specialist research training is described in the design and implementation of the study, interpretation of findings, and design of the intervention model and tools. Benefits that emerged from co-researcher involvement in this process, to the community and to the co-researchers themselves, are described.  相似文献
