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.

Dispute Settlement under the Rome Statute of the International Criminal Court: Article 119 and the Possible Role of the International Court of Justice

This paper examines the dispute settlement procedure establishedby Article 119 of the Rome Statute of the International CriminalCourt, with particular attention paid to whether that provisioncreates any relationship between the International CriminalCourt and the International Court of Justice. The paper firstdiscusses the jurisdictional reach of Article 119, detailingthe types of disputes addressed in its two subsections and themanner in which such disputes are to be handled. Secondly, itfocuses on the possibility of referral of disputes covered inArticle 119(2) to the International Court of Justice. Althoughthe provision expressly contemplates such a referral, it remainsunclear whether the provision adequately supports the jurisdictionof the International Court of Justice in accordance with theStatute of that Court. The paper goes on to suggest ways inwhich the International Criminal Court Assembly of States Partiescan take steps to improve the likelihood that such referralwould be deemed proper in order to enhance the possible andfinal settlement of disputes.     

Youth’s Causal Beliefs About Success: Socioeconomic Differences and Prediction of Early Career Development

Youth’s career attainment is associated with socioeconomic background, but may also be related to their beliefs about causes of success. Relationships between 17-year-olds’ socioeconomic status (SES) and causal beliefs about success, and whether these beliefs predict career attainment after completing a vocational or university degree were examined using data from the German Socio-Economic Panel Study (n?=?997, 48.5% female). Youth with higher SES parents and those who attended higher levels of high schools were less likely to believe that success in society is due to external causes, but SES was unrelated to the belief that success is due to personal merit or ability. Youth who believe that success is due to external causes attained lower income, occupational prestige, and job autonomy, and slower increases in income over time. There were also significant indirect effects of youth’s parents’ SES and their own high school levels on career attainment through such external causal beliefs; merit beliefs, by contrast, were largely unrelated to career attainment. These results suggest that beliefs about external causes of success may uniquely contribute to the transmission and maintenance of SES across generations and over time.     

The limits of environmental remediation protocols for environmental justice cases: lessons from Vieques,Puerto Rico

The United States Federal Government has repeatedly put the people of Vieques, Puerto Rico in harm’s way due to the injurious after-effects of air-to-ground weapons testing. Most of the harm happened during the Navy’s 70 years on the island. Yet, the harm continues today considering that aspects of the cleanup count as continued acts of environmental injustice, viewed within the context of the island’s colonial history. Usually, this harm deals with public health issues, but the remediation protocols do not account for considerations such as cultural identity and heritage. This paper shows how the procedures for environmental remediation in Vieques qualify as a case of environmental injustice according to Robert M. Figueroa’s ‘environmental justice paradigm.’ The aim of employing this kind of approach is to pinpoint the underlying reasons why this is a case of environmental injustice.     

Sleep Disturbance and Depressive Symptoms in Adolescence: The Role of Catastrophic Worry

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.     

Lawyers' Questioning: The Effect of Confusing Questions on Witness Confidence and Accuracy

The present study investigated the effect on witness confidence and accuracy of confusing questions often used by attorneys in court. Participants viewed a videotaped film and were individually questioned about the incident 1 week later. Half the participants were asked questions using six categories of confusing questions (negatives, double negatives, leading, multiple questions, complex syntax, and complex vocabulary); the remaining half were asked for the same information using simply phrased equivalents. Confusing questions reduced participant-witnesses' accuracy and suppressed confidence–accuracy relationships compared with the condition where simplified alternatives were asked. Witness performance was impaired by the fact that mock-witnesses rarely asked for a confusing question to be explained or qualified their answers. This experiment demonstrates the importance of ensuring that lawyers ask witnesses simple, clear, questions.
