Crime Event

Drawing from perspectives emphasizing environmental crime event components, this study identifies the predictors and contexts of unsolved and solved sexual offenses against women by strangers. Police data were obtained from 542 cases in Queensland. Hierarchical logistical regression was adopted to analyze variables relating to situational, contextual, and offender–victim interaction elements. Common contexts were examined using conjunctive analysis. Cases were significantly likely to remain unsolved if the offender used minimal force, or if the victim was walking outside at the time of initial contact. Conversely, solved cases were significantly associated with offender prior consumption of alcohol/drugs, bystander presence, and vehicle use. Crimes with higher criminal “effectiveness” and lower levels of victim interaction tended to be associated with unsolved sexual offenses.

Crime Script

This study identifies the first crime script for unsolved stranger sexual offenses against women. The purpose is to better understand the crime-commission process of solved and unsolved stranger sexual offenses and identify potential points of intervention for prevention purposes. Crime script analysis was performed on 542 solved ( n = 265) and unsolved ( n = 277) cases based on police data in Queensland, Australia, followed by a comparison between solved and unsolved crime scripts. Results showed that unsolved offenses tended to be associated with the following factors: the offender fleeing/desisting, using minimal force, less intrusive sexual outcomes, and less verbal engagement with the victim. In these cases, there was a lack of information regarding forensic evidence, behavioral clues, and eyewitness leads. This highlights the relevance of focusing on situational crime prevention and policing strategies that may deter stranger sexual crimes at the earliest stages of the script.

The Impact

Background: Ethical issues have been raised about using the psychological autopsy approach in the study of suicide. The impact on informants of control cases who participated in case-control psychological autopsy studies has not been investigated. Aims: (1) To investigate whether informants of suicide cases recruited by two approaches (coroners’ court and public mortuaries) respond differently to the initial contact by the research team. (2) To explore the reactions, reasons for participation, and comments of both the informants of suicide and control cases to psychological autopsy interviews. (3) To investigate the impact of the interviews on informants of suicide cases about a month after the interviews. Methods: A self-report questionnaire was used for the informants of both suicide and control cases. Telephone follow-up interviews were conducted with the informants of suicide cases. Results: The majority of the informants of suicide cases, regardless of the initial route of contact, as well as the control cases were positive about being approached to take part in the study. A minority of informants of suicide and control cases found the experience of talking about their family member to be more upsetting than expected. The telephone follow-up interviews showed that none of the informants of suicide cases reported being distressed by the psychological autopsy interviews. Limitations: The acceptance rate for our original psychological autopsy study was modest. Conclusions: The findings of this study are useful for future participants and researchers in measuring the potential benefits and risks of participating in similar sensitive research. Psychological autopsy interviews may be utilized as an active engagement approach to reach out to the people bereaved by suicide, especially in places where the postvention work is underdeveloped.

Platelet Spreading

SummaryIn order to explore further the mechanism by which glycoprotein GPIIb-IIIa promotes platelet vessel wall interaction, platelet adhesion to subendothelium was studied in an annular chamber in which subendothelium from rabbit aorta was exposed at a shear rate of 2,600 s−1 to blood from patients with thrombasthenia. Perfusions were conducted for each of 5 exposure times (1 ,2,3, 5 and 10 min), and the percent surface coverage of the vessel segment with platelets in the contact (C) and spread (S) stage was determined. Increased values of platelet contact (C) were obtained in thrombasthenia at all exposure times; this finding is consistent with a defect in platelet spreadirg, based on a previously described kinetic model of platelet attachment to subendothelium. According to this model of attachment, increased values of platelet contact (C) at a single exposure time may be indicative of either a defect in spreading (S) or initial contact (C), but multiple exposures will result in increased contact only for defects which are related to defectiye platelet spreading (s).The results obtained over a broad range of exposure times provide more conclusive evidence that GPIIb-IIIa mediates platelet spreading than those previously obtained at single exposure times.
