The adoption of children from out-of-home care: how decision-makers explain the low rates of adoption in Victoria,Australia

The adoption of children from out-of-home care is uncommon in Australia and rarely occurs in the state of Victoria. This paper reports on how professionals involved in making decisions about the permanent placement of children explain the current rates of adoption from out-of-home care in Victoria. Interviews were conducted with eight child welfare specialists, eight adoption and permanent care specialists and five judicial officers. The current low rates of adoption were attributed to the effect of current legislation, the impact of past adoption practices and the establishment of a culture in Victoria in which adoption is now rarely considered an option for children in out-of-home care.     

Effects of Re‐heating Tissue Samples to Core Body Temperature on High‐Velocity Ballistic Projectile–tissue Interactions

Damage produced by high‐speed projectiles on organic tissue will depend on the physical properties of the tissues. Conditioning organic tissue samples to human core body temperature (37°C) prior to conducting ballistic experiments enables their behavior to closely mimic that of living tissues. To minimize autolytic changes after death, the tissues are refrigerated soon after their removal from the body and re‐heated to 37°C prior to testing. This research investigates whether heating 50‐mm‐cube samples of porcine liver, kidney, and heart to 37°C for varying durations (maximum 7 h) can affect the penetration response of a high‐speed, steel sphere projectile. Longer conditioning times for heart and liver resulted in a slight loss of velocity/energy of the projectile, but the reverse effect occurred for the kidney. Possible reasons for these trends include autolytic changes causing softening (heart and liver) and dehydration causing an increase in density (kidney).     

The Effect of Framing Actuarial Risk Probabilities on Involuntary Civil Commitment Decisions

Despite a proliferation of actuarial risk assessment instruments, empirical research on the communication of violence risk is scant and there is virtually no research on the consumption of actuarial risk assessment. Using a 2 × 3 Latin Square factorial design, this experiment tested whether decision-makers are sensitive to varying levels of risk expressed probabilistically and whether the framing of actuarial risk probabilities is consequential for commitment decisions. Consistent with research on attribute framing, in which describing an attribute in terms of its complement leads to different conclusions, this experiment found that the way actuarial risk estimates are framed leads to disparate commitment decisions. For example, risk framed as 26% probability of violence generally led decision-makers to authorize commitment, whereas the same risk framed in the complement, a 74% probability of no violence, generally led decision-makers to release. This result was most pronounced for moderate risk levels. Implications for the risk communication format debate, forensic practice and research are discussed.     

Survival of the Fairest: Examining HUD Reviews of Assessments of Fair Housing

ABSTRACT

In 2015, the U.S. Department of Housing and Urban Development (HUD) issued the Affirmatively Furthering Fair Housing (AFFH) Rule, arguably the most significant federal effort in a generation to address place-based disparities in access to opportunity and to advance fair housing. In 2018, HUD suspended the rule, it said in part because of the resources it was expending to implement it and in part because of the large share of municipal plans that HUD determined had failed to meet the rule’s requirements. In this article, we present the first analysis of the fair housing plans that HUD did not accept, examining how municipalities failed to meet the rule's requirements, what those failures imply about advancing fair housing, and the extent to which HUD’s enforcement strategy was working before the suspension. Our analysis shows that HUD engaged in detailed reviews of municipalities’ Assessments of Fair Housing and provided constructive feedback. The most common issue with which municipalities struggled was setting realistic goals that would actually advance fair housing and creating measurable metrics and milestones to gauge progress. Several municipalities neglected to conduct thorough regional analyses or analyses of all relevant disparities in access to opportunity. Both shortcomings reflect broader challenges municipalities face in advancing fair housing, particularly in identifying strategies that address interconnected causes of disparities in access to opportunity and in building regional support to address those causes.     

Addressing the National Academy of Sciences' challenge: a method for statistical pattern comparison of striated tool marks

In February 2009, the National Academy of Sciences published a report entitled "Strengthening Forensic Science in the United States: A Path Forward." The report notes research studies must be performed to "…understand the reliability and repeatability…" of comparison methods commonly used in forensic science. Numerical classification methods have the ability to assign objective quantitative measures to these words. In this study, reproducible sets of ideal striation patterns were made with nine slotted screwdrivers, encoded into high-dimensional feature vectors, and subjected to multiple statistical pattern recognition methods. The specific methods employed were chosen because of their long peer-reviewed track records, widespread successful use for both industry and academic applications, rely on few assumptions on the data's underlying distribution, can be accompanied by standard confidence levels, and are falsifiable. For PLS-DA, correct classification rates of 97% or higher were achieved by retaining only eight dimensions (8D) of data. PCA-SVM required even fewer dimensions, 4D, for the same level of performance. Finally, for the first time in forensic science, it is shown how to use conformal prediction theory to compute identifications of striation patterns at a given level of confidence.     

Current practices by forensic anthropologists in adult skeletal age estimation

When determining an age estimate from adult skeletal remains, forensic anthropologists face a series of methodological choices. These decisions, such as which skeletal region to evaluate, which methods to apply, what statistical information to use, and how to combine information from multiple methods, ultimately impacts the final reported age estimate. In this study, a questionnaire was administered to 145 forensic anthropologists, documenting current trends in adult age at death estimation procedures used throughout the field. Results indicate that the Suchey-Brooks pubic symphysis method (1990) remains the most highly favored aging technique, with cranial sutures and dental wear being the least preferred, regardless of experience. The majority of respondents stated that they vary their skeletal age estimate process case-by-case and ultimately present to officials both a narrow and broad possible age range. Overall, respondents displayed a very high degree of variation in how they generate their age estimates, and indicated that experience and expertise play a large role in skeletal age estimates.     

Reading in Community,Reading for Community: A Survey of Book Clubs in Regional Australia

Worries about weakening community are central to assessments of modern Australia, yet it is easy to overlook the everyday ways we “do” and participate in community life. Book clubs are one area of community participation largely ignored by researchers despite the local and national proliferation of such clubs. Surveying twenty-two book groups and ninety-seven book club members, this study investigates the roles that book clubs play in the cultural and community life of a regional area of Tasmania. The results show that book clubs promote regular intellectual engagement and provide for a distinct female sociality that consolidates and creates new social connections and function as everyday “escape attempts” from the obligations of work and family. We suggest that the support and development of local book club programs may have considerable potential as a strategy for Australian governments and communities to foster a sense of community.
