Improved Area of Origin Estimation for Bloodstain Pattern Analysis Using 3D Scanning

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.     

Grief reactions and effective negotiation

Conclusion In the event of death, society has in place a wide range of rituals and supports designed to help mourners deal with their grief. It may be that assigning blame and seeking legal recourse has become a significant ritual for those who have sustained other types of losses and, in some situations, loss through death as well. However, unlike societal death rituals, which guide the mourners, no guidelines exist to help negotiators address the impact of grief on their clients. Thus, in this article, insights gleaned from studies of grief, loss, and separation have been examined in an effort to develop an awareness of the impact of grief reactions on the parties to negotiation.Grief reactions—ranging from denial, bargaining, anger, depression, and guilt to acceptance—serve a useful purpose for those who have sustained grievous losses. Consequently, a better understanding of grief factors may be advantageous to negotiators and, more importantly, to their clients. Such considerations may help challenge perceptions of other parties that may otherwise be prejudicial to one's client (as in the Lindy Chamberlain case) and assist negotiators in trying to anticipate, and thus protect their clients from, grief-related reactions of other parties. In the large number of cases where negotiation and settlement discussions are not only critical but also decisive, grief theory may provide negotiators with better insight into client, and other party, interests and may help them to formulate advice and intervention strategies that take the impact of various grief reactions into account.

MEDIATION AND THE DEPENDENCY COURT

This study examines mediation in three dependency courts in the United States and identifies major policy questions regarding the use of mediation in these proceedings.     

A NEW LOOK AT AN OLD ISSUE:

In 1997, the Office of Child Support Enforcement initiated the State Child Access and Visitation (AV) Grant Program, which involves annual awards of $10 million to states to promote the development of programs to alleviate access problems. Telephone interviews with 970 parents who used mediation, parent education, and supervised visitation programs funded by AV grants in nine states revealed that the programs are reaching diverse groups of parents including many low-income, non-White, and unmarried parents who receive no other type of access assistance. The programs also appear to be achieving the major objectives posited for them by the federal government. One-third to one-half of noncustodial parents in every program type reported that parent–child contact increased following program participation, with supervised visitation users who typically had the lowest levels of parent–child contact reporting a significant increase in the number of days of contact. A review of child support records for 173 program users in three states revealed that child support payments increased among participants following program participation, especially for never-married parents who paid a significantly higher proportion of what they owed. These findings are similar to results reported in a five-state study of mediation programs funded by AV grants that was conducted by the Office of the Inspector General. However, both studies have some serious limitations, including low response rates and the absence of a nontreatment comparison group.     

CHILD SUPPORT IN THE UNITED STATES

This article reports on the results of a telephone survey conducted with a random sample of households screened for eligibility to receive child support in the state of Colorado. Despite the recent enactment of ambitious child legislation at the state and federal levels, the accounts of 731 custodial parents reveal a massive level of unmet need, with child support problems being most extreme for those never married to the chilďs other parent. These mothers typically lack an order establishing a legal obligation to pay child support and have incomes that fall below the poverty level. Overall, women of Colorado with child support orders received only about half of the support they were due, and 73 per cent of all women due support reported that they had experienced problems in collecting support either currently or in the past. The average amount of back due child support owed to the 60 per cent of women in the sample who reported an arrearage was $12,000. Analysis revealed that payment behaviour tracked with the length of time since separation with payment patterns worsening over time and irregular visitation and/or the presence of problems around child access. Female obligors exhibited the same payment patterns as their male counterparts but were more apt to maintain visitation. The article documents the dramatic, negative economic consequences of irregular or missing child support payments for custodial parents, and discusses the additional legal and financial commitments needed to improve the situation. The efficacy of private child support transfers to achieve an adequate standard of living for all children is called into question.
