The Probabilistic Genotyping Software STRmix: Utility and Evidence for its Validity

Forensic DNA interpretation is transitioning from manual interpretation based usually on binary decision‐making toward computer‐based systems that model the probability of the profile given different explanations for it, termed probabilistic genotyping (PG). Decision‐making by laboratories to implement probability‐based interpretation should be based on scientific principles for validity and information that supports its utility, such as criteria to support admissibility. The principles behind STRmix? are outlined in this study and include standard mathematics and modeling of peak heights and variability in those heights. All PG methods generate a likelihood ratio (LR) and require the formulation of propositions. Principles underpinning formulations of propositions include the identification of reasonably assumed contributors. Substantial data have been produced that support precision, error rate, and reliability of PG, and in particular, STRmix?. A current issue is access to the code and quality processes used while coding. There are substantial data that describe the performance, strengths, and limitations of STRmix?, one of the available PG software.     

Did Post-Floyd et al. Reforms Reduce Racial Disparities in NYPD Stop,Question, and Frisk Practices? An Exploratory Analysis Using External and Internal Benchmarks

Various methodological approaches to constructing external and internal benchmarks have been applied to estimate racial bias in police stop, question, and frisk (SQF) patterns. We apply an external benchmark of the race of the residential population and an internal benchmark of similarly-situated stops to estimate if racial disparities in New York City SQF data were impacted by the Floyd, et al. v. City of New York court settlement. We find that after the settlement, the racial composition of census tracts were no longer significant predictors of the stop rate after controlling for reported crime, socioeconomic factors, and police precincts. We further find that differences in SQF outcomes and hit rates between Blacks and Hispanics and similarly-situated others diminished substantially after the settlement. These findings suggest that court reforms may be an effective method for reducing racial disparities in SQF patterns.     

The Will to Change: Lessons from Canada's Successful Decarceration of Youth

In 1997, Canada's youth custodial facilities held 3825 sentenced youths. Eighteen years later, this number was 527—an 86 percent reduction. Overall youth imprisonment (sentenced + pretrial detention) decreased by approximately 73 percent. This paper uses Canada's successful decarceration of youths to understand what might be learned about decarceration more broadly. By examining the reforms that transpired in Canada's treatment of young offenders since the 1960s and the political/cultural shifts that occurred since the 1990s, we demonstrate that the decline resulted from changes occurring in various parts of the system. Finally, we contrast this decarceration with more than 60 years of relative stability of Canadian adult imprisonment rates as well as Canada's failure to substantially decrease youth pretrial detention in order to identify those factors seemingly necessary to reduce imprisonment more generally.     

Protecting Journalists’ Sources Without a Shield: Four Proposals

Journalists’ right to protect the identities of their confidential sources relies on an inconsistent set of court decisions based on constitutional and common law interpretations and state statutes. Efforts to bring some consistency to federal law through the passage of a shield law have stalled while journalists face new threats because of the vulnerability of their communications to discovery and monitoring by third parties. Also, the entry of non-professional communicators into the news ecosystem is causing courts to reevaluate and redefine long-standing protections. This article proposes four ways that sources could be better protected from unmasking without the passage of a shield law: improving whistleblower laws to better protect people who report illegal or unethical actions to the media; vastly reducing the number of government secrets to make “leaking” less attractive or necessary; changing legal strategy to focus on protecting the anonymity of sources instead of the rights of journalists to keep secrets; and more widespread and intelligent use of encrypted applications and software could all improve the security of journalistic sources. Because of the complexity of amending multiple whistleblower protection laws and changing the government’s document classification system, the article argues that the best solutions may be to persuade news organizations to change legal tactics and to use better encryption technology.     

The impact of student-generated digital flashcards on student learning of constitutional law

This article describes, evaluates and reflects upon student creation of cloud-based digital flashcards as an authentic formative and summative assessment task designed for the deep learning of constitutional law. The usefulness of digital flashcards in online legal education is explored. The undergraduate law student participants in the study responded differently to the assessment task depending upon the constitutional law topic they were assigned, the perceived relevance of constructing digital flashcards to professional practice and how they reacted to this creative task. Building digital flashcards provides a potentially powerful authentic assessment task for the study of constitutional law provided it is designed to support semester long creation, validation and sharing of digital flashcards that students perceive as professionally relevant and educationally useful. Student recommendations for designing an assessment task involving the creation of digital flashcards are evaluated.     

Breaking up is hard to do: the economic impact of provisional funding contingent upon evidence development

Funding contingent upon evidence development (FED) has recently been the subject of some considerable debate in the literature but relatively little has been made of its economic impact. We argue that FED has the potential to shorten the lag between innovation and access but may also (i) crowd-out more valuable interventions in situations in which there is a fixed dedicated budget; or (ii) lead to a de facto increase in the funding threshold and increased expenditure growth in situations in which the programme budget is open-ended. Although FED would typically entail periodic review of provisional or interim listings, it may prove difficult to withdraw funding even at cost/QALY ratios well in excess of current listing thresholds. Further consideration of the design and implementation of FED processes is therefore required to ensure that its introduction yields net benefits over existing processes.     

Small changes, big results: Legislative voting behavior in the presence of new voters

Changes in district boundaries in small magnitude electoral systems can have substantive consequences for representation. In the U.S., each decennial redistricting cycle infuses House districts with a large number of new voters, changing personal representation for many citizens. What effect does the influx of these new voters exert on member behavior? By assessing the extent of this change in constituencies in conjunction with member voting behavior on roll calls, we can determine if significant changes to a congressional district impact post-redistricting legislative behavior. Using panel data estimators and various measures of legislator behavior, we show evidence that supports this claim. Our findings have notable implications for debates over representation and electoral accountability in legislative assemblies.     

Exploring Risk: Potential Static,Dynamic, Protective and Treatment Factors in the Clinical Histories of Female Sex Offenders

Despite nearly a century of knowledge indicating a significant number of women engaging in sexual activities with children, the phenomenon has not yet been fully acknowledged. Recently, however, there has been a marked increase in research in this area. However, due to the relatively small numbers of detections or convictions there remains a lack of data regarding: (1) the specific clinical characteristics of female sex offenders; and (2) how these clinical factors link to re-offending and treatment need. The following study examines potential risk, protective, and treatment factors that are highlighted through the process of clinical intervention, using an adapted version of the Beech and Ward (2004) risk framework. We describe how female sex offenders typically display clinical deficits in the same risk domains as their male counterparts, while noting the ways in which these deficits manifest in this population. In addition, we compare these vulnerability factors in four established types of female sex offender.
