An important component of crime scene reconstruction is bloodstain pattern analysis (BPA). Where BPA concerns impact patterns, estimating the area of origin is critical information for scene reconstruction. Traditionally, this is achieved by measuring individual bloodstains and performing trigonometric calculations; however, 3D scanning has been proposed as a viable alternative for overcoming logistical and practical concerns with the manual method. Therefore, this project aimed to establish whether the FARO Focus 3D scanner and FARO Zone 3D software can improve the accuracy of area of origin estimates relative to the manual method. We created a series of eight bloodstain impact patterns and performed paired analysis using the two methods to estimate areas of origin for each pattern. Our data suggested that FARO-derived estimates were generally more accurate than using the manual method. FARO-estimated heights of origin areas were generally closer to the true distance. Both methods underestimated the distance from the wall for most patterns originating 150mm or greater from the wall, but overestimated distances for patterns originating closer to the wall. The degree to which distances were underestimated increased significantly the further the blood source was from the wall and was greater for FARO-derived estimates. The results of this research contribute to the validation of these instruments for operational implementation for BPA and should be considered alongside the practical benefits of 3D scanning relative to manual methods. Further, 3D scanning can provide reliable BPA reconstruction documentation for technical review and court presentation. 相似文献

AbstractWhat is ‘relational theorizing’ in International Relations and what can it offer? This article introduces a thematic section that responds to these questions by showing two things. First, relational theorizing is not a doctrine or a method, but a set of analyses that begin with relations rather than the putative essences of constitutively autonomous actors. Second, relational theorizing has emerged from different geo-linguistic traditions, and a relational approach to International Relations (IR) can offer the language and space for increased and productive engagement beyond Anglophone scholarship. This thematic section takes a significant step in this direction by staging a dialogue between Sinophone and Anglophone scholarship on relational IR theorizing. Such an engagement shows points of comparison and contrast, convergence and divergence. In this way, the essays presented here contribute to developing a more ‘global’ IR. 相似文献

Unwanted sexual attention (UWSA) encompasses unsolicited verbal comments, gestures, stares, and other noncontact behaviors made regarding one's sexuality and physical appearance. The present study examined the correlates and impact of such UWSA perpetrated toward girls by family members. The first objective of the study was to explore whether family climate is associated with intrafamilial UWSA. This included looking at three types of dysfunctional parenting styles (unaffectionate, unavailable, and patriarchal) as well as exploring the co-occurrence of UWSA by adult and child relatives. The second objective was to then measure the impact of such intrafamilial UWSA on childhood emotional health, after controlling for parenting style and the experience of more traditional forms of child sexual abuse (CSA). Of the 296 university women (mean age = 19) who participated in the study, 70% (N = 206) reported UWSA from a family member prior to age 18. Whereas each dysfunctional parenting style was related to presence of UWSA, a simultaneous multiple regression analysis indicated that two of the parenting styles, patriarchal and parental unavailability, also predicted frequency of nonphysical UWSA within the family. Presence of UWSA from a child relative was significantly correlated with presence of UWSA from an adult relative. Additionally, a hierarchical multiple regression, entering the three parenting styles simultaneously in the first step, childhood sexual abuse in the second step, and familial UWSA in the last step, indicated that the frequency of UWSA by family members significantly predicted poorer childhood mental health when controlling for the other variables. Overall, results indicate that while the specific parenting styles which co-occur with UWSA may be detrimental in their own right, the impact of UWSA on girls appears to be above and beyond that of either parenting styles or CSA. Clinical implications are discussed. 相似文献

This article considers the claim in the government's White Paper, Justice for All , to put victims and witnesses at the heart of the criminal justice system and argues that there is an unresolved tension within the paper between instrumentalist crime control concerns and intrinsic concerns for the rights of victims and witnesses. It is argued that many of the proposals now contained in the latest Criminal Justice Bill are so preoccupied with rebalancing the system away from offenders that they risk doing injustice to defendants with little tangible benefit to victims and witnesses in terms of rights and remedies. 相似文献

This article explores the concept of authorisation in relationto the possible liability of manufacturers and suppliers oftechnology if, and when, their technology is used by purchasersor other users to infringe copyright. Cases over the last 30years brought by copyright owners or holders against the manufacturersand suppliers of technology which has the potential to infringecopyright are examined, as well as the differing copyright lawsin Australia and the United States relating to the authorisationof copyright infringement. The article concludes with a discussionon the current legal approaches to authorisation and on possiblefuture approaches. 相似文献

We consider the problem of drawing inferences within a legal framework when a person is a suspect for two separate offences. Although we are primarily concerned with scientific evidence the issue inevitably arises as to how that evidence interacts with other, non-scientific evidence. We show that, in this particular context, the evidence can be conveniently classified into three categories that concern, respectively: the first crime only; the second crime only; and evidence that relates to similarities between the two crimes. Two case examples are considered and we consider DNA, fibres and eyewitness evidence. These are viewed from the perspective of a prosecutor who has to decide whether or not to charge a suspect with one or both crimes. Graphical sensivity analyses are presented which have features that are not intuitively obvious. 相似文献

This article challenges the assumption that their future children's welfare is a relevant consideration when deciding whether to provide a person with assisted conception services. It does not argue that infertility treatment ought to be available as of right. Rather, this article's proposal is that section 13(5) – which specifies that no-one shall receive assistance with conception unless account has first been taken of the welfare of any child who might be born – should be deleted from the Human Fertilisation and Embryology Act 1990. Extending the 'welfare principle' to decisions taken prior to a child's conception is shown to be unjust, meaningless and inconsistent with existing legal principle. 相似文献

The relationship between association with deviant peers and offending is a longstanding interest in criminology, however, the mechanisms that produce the relationship are seldom investigated. As a result, theoretical links between differential association and offending are often speculative. Differential association theorists maintain that interaction with deviant peers results in cognitive changes that make offending more attractive. Others contend that peers' influence on offending is enacted via group situations where associates encourage crime by offering opportunities or situational inducements. Using data from the National Youth Survey (NYS), this study explored the influence of delinquent friends' behaviors and attitudes on general, group, and solo offending for three crimes. OLS regression analyses supported differential association theory as originally written and no evidence was found that its effects were contingent on the presence of co-offenders. Implications of this exploratory analysis for differential association theory are provided along with directions for future research. 相似文献
