Mammalian whole blood sources are often used for forensic research and training when human samples cannot be sourced. While porcine, ovine and equine blood have been shown to be viable alternatives to whole human blood for forensic purposes, procurement can still pose a problem, especially for smaller and remote institutions. This work explores the use of whole bovine blood for basic bloodstain simulation. Sample preparation through the addition of ACD-A anticoagulant was optimized and storability was explored. Viscosity, surface tension, density, and packed cell volume, four fluid properties relevant to bloodstain pattern analysis, were monitored over four days and in two temperature conditions. Linear mixed models accounting for variation in the donor demonstrated that these fluid properties of the bovine blood changed predictably over time and with temperature. Whole bovine blood with 12.5% v/v ACD-A was found to be viable for use in basic bloodstain simulation at ambient and physiological temperature. 相似文献

Formalin-fixed tissues provide the medical and forensic communities with alternative and often last resort sources of DNA for identification or diagnostic purposes. The DNA in these samples can be highly degraded and chemically damaged, making downstream genotyping using short tandem repeats (STRs) challenging. Therefore, the use of alternative genetic markers, methods that pre-amplify the low amount of good quality DNA present, or methods that repair the damaged DNA template may provide more probative genetic information. This study investigated whether whole genome amplification (WGA) and DNA repair could improve STR typing of formaldehyde-damaged (FD) tissues from embalmed cadavers. Additionally, comparative genotyping success using bi-allelic markers, including INDELs and SNPs, was explored. Calculated random match probabilities (RMPs) using traditional STRs, INDEL markers, and two next generation sequencing (NGS) panels were compared across all samples. Overall, results showed that neither WGA nor DNA repair substantially improved STR success rates from formalin-fixed tissue samples. However, when DNA from FD samples was genotyped using INDEL and SNP-based panels, the RMP of each sample was markedly lower than the RMPs calculated from partial STR profiles. Therefore, the results of this study suggest that rather than attempting to improve the quantity and quality of severely damaged and degraded DNA prior to STR typing, a more productive approach may be to target smaller amplicons to provide more discriminatory DNA identifications. Furthermore, an NGS panel with less loci may yield better results when examining FD samples, due to more optimized chemistries that result in greater allelic balance and amplicon coverage. 相似文献

It is common for researchers using animal or human remains for scientific study to freeze samples prior to use. However, effects of freezing on bone macro‐ or microstructure are relatively unknown. The research objective of this study was to determine whether freezing could potentially bias experimental results by analyzing changes in bone mineral density (BMD) with the freezing of remains over time. Eight fetal pigs were scanned to determine their initial BMD before freezing. Three piglets underwent a freeze‐thaw cycle to assess the effects of the freezing process. Four piglets were frozen and scanned weekly for 20 weeks to assess freezing over time. The overall average between the fresh initial scan and final frozen scan was significantly different (p < 0.001). Per contra, the final thawed BMD scans did not differ from the initial fresh scan (p = 0.418). Thus, completely thawed remains are recommended for experimental studies. 相似文献

Currently, there is an expansive body of victimization literature within the criminal justice field, which covers a number of essential topics such as victimization trends and patterns, short-and long-term effects of victimization, as well as specific effects of intimate partner violence and sexual assault victimization. Despite the variety of topics examined by empirical research, there is a noticeable lack of discourse pertaining to civil legal services for crime victims. This study is among the first to take a close look at civil legal services for victims by exploring three uncharted areas including: (a) service providers’ knowledge of civil legal services, (b) the legal needs of crime victims and available services, and (c) barriers between victims and accessing civil legal services. Using quantitative and qualitative data from interviews with service providers, policy implications and future research recommendations are discussed. 相似文献

This article catalogues and analyzes the litigating behavior of four of the leading New Christian Right Public Interest Law Firms (NCR PILFs). Consistent with the finding from judicial politics that all PILFs seek first and foremost to have policy influence, we find that most of the litigation these PILFs invest in is either explicitly or implicitly religious or mission driven. However, we also observe a trend of increased participation in secular cases by the two largest NCR PILFs in our study. Through in‐depth, qualitative content analysis of the briefs submitted in these secular cases, we show that while some of this behavior can be attributed to organizational maintenance or coalitional goals, most of this secular participation appears motivated by a desire to influence the legal rules rather than the outcome of the particular case. In doing so, this article shows how PILFs engage with an increasingly complex legal and political landscape. 相似文献

Successive multiparty elections in sub-Saharan Africa are associated with incremental democratization. Yet tests in other regions are less than encouraging. Non-significant findings on Latin America and post-communist Eurasia, as well as conceptual criticism regarding the theory’s application in the contemporary Middle East, suggest that this may be a case of African exceptionalism. This article moves these debates forward by posing a comprehensive, global set of tests on the democratizing effect of elections. We seek to establish the scope conditions of the argument geographically, temporally, and substantively. Although we find a correlation between reiterated multiparty elections and improvements in the liberal-democratic components of electoral regimes globally since 1900, the relationship is only substantial in the period since the onset of the third wave of democracy. Experiences with iterated multiparty elections have substantive importance for democratization in sub-Saharan Africa, the post-communist region, Latin America and the Caribbean, and Asia. For the Middle East and North Africa, the relationship is weaker and less robust. Finally, the results suggest that reiterated sequences of multiparty elections are associated with improvements to liberal and deliberative components of democracy more so than egalitarian components. 相似文献

Parents compare their children to one another; those comparisons may have implications for the way mothers and fathers treat their children, as well as their children’s behavior. Data were collected annually for three years with parents, firstborns, and secondborns from 385 families (Time 1 age: firstborns, 15.71, SD?=?1.07, 52% female; secondborns, 13.18, SD?=?1.29, 50% female). Parents’ beliefs that one child was better behaved predicted differences in siblings’ reports of parent-child conflict. Additionally, for siblings close in age, mothers’ comparisons at Time 1 predicted youth’s problem behavior at Time 3 through siblings’ differential conflict with mothers. The results support and extend tenets from Social Comparison and Expectancy Value theories in regards to social comparison within families. 相似文献

A growing body of literature explores the process of coproduction by citizens and government employees in providing goods and services, yet research that attempts to link coproduction to organizational performance offers contradictory findings. It is possible that these conflicting results are a consequence of trying to compare distinct categories of coproduction. This study identifies types of coproduction, classified by which organizational tasks citizens can influence during stages of policy design and implementation, and tests whether these types have different effects on student proficiency in Mathematics and English Language Arts using data from New York City schools between 2007 and 2009. This study then tests the degree to which different types of coproduction moderate the negative effect of environmental turbulence on performance. Results confirm that types of coproduction have varying effects on organizational performance and can reduce, and even eliminate, the negative effect of a turbulent environment on student outcomes. 相似文献

An important empirical literature evaluates whether voters are rational by examining how electoral outcomes respond to events outside the control of politicians, such as natural disasters or economic shocks. The argument is that rational voters should not base electoral decisions on such events, so evidence that these events affect electoral outcomes is evidence of voter irrationality. We show that such events can affect electoral outcomes, even if voters are rational and have instrumental preferences. The reason is that these events change voters' opportunities to learn new information about incumbents. Thus, identifying voter (ir)rationality requires more than just identifying the impact of exogenous shocks on electoral fortunes. Our analysis highlights systematic ways in which electoral fortunes are expected to change in response to events outside incumbents' control. Such results can inform empirical work attempting to identify voter (ir)rationality. 相似文献
