Using subsampling to estimate the strength of handwriting evidence via score-based likelihood ratios

The likelihood ratio paradigm has been studied as a means for quantifying the strength of evidence for a variety of forensic evidence types. Although the concept of a likelihood ratio as a comparison of the plausibility of evidence under two propositions (or hypotheses) is straightforward, a number of issues arise when one considers how to go about estimating a likelihood ratio. In this paper, we illustrate one possible approach to estimating a likelihood ratio in comparative handwriting analysis. The novelty of our proposed approach relies on generating simulated writing samples from a collection of writing samples from a known source to form a database for estimating the distribution associated with the numerator of a likelihood ratio. We illustrate this approach using documents collected from 432 writers under controlled conditions.     

Examining What Makes Violent Crime Victims Unique: Extending Statistical Methods for Studying Specialization to the Analysis of Crime Victims

Objectives

Much victimization research focuses on specific types of crime victims, which implies that the factors responsible for some victimization outcomes are distinct from others. Recent developments in victimization theory, however, take a more general approach, postulating that victimization regardless of type will share a similar basic etiology. This research examines how and whether the risk factors that are associated with violent victimization significantly differ from those that predict nonviolent victimization.

Methods

Using data from 3,682 Kentucky youth, we employ Osgood and Schreck??s (2007) Item Response Theory-based statistical approach for detecting specialization to determine the properties and predictors of tendencies for individuals to fall victim to specific types of crime.

Results

Findings show that victims typically experience varied outcomes, but some victims have a clear tendency toward violent victimization and that it is possible to predict this tendency.

Conclusions

The findings indicate that a more nuanced general approach, one that accounts for tendencies toward specific victimization outcomes, might add insight about the causes of victimization. This research also shows how statistical methods designed to examine offense specialization can add value for research on victimization.     

Moderators of Response to Motivational Interviewing for Partner-violent Men

Careful attention to motivation for change may enhance the effects of interventions for partner-violent men. The present study tested predictions about differential response to a two-session motivational intake (MI) for partner-violent men, which was compared to a structured intake (SI) control. For those who were initially reluctant to change, MI produced greater forward movement in stage of change. For those who claimed to have already solved their problems with partner abuse, MI produced greater backward movement in stage of change and greater homework compliance in subsequent group cognitive-behavioral therapy (CBT). MI led to a stronger collaborative working alliance for those high in contemplation of change, and greater group session attendance for those with high trait anger. Contrary to hypotheses, analyses of post-CBT partner assault revealed a differentially greater benefit of MI for participants with lower levels of pretreatment contemplation and trait anger. The findings provide qualified support for the expectation that MI has the greatest beneficial effects on those who appear initially reluctant to change.     

What is Left of the Law and Society Paradigm after Critique? Revisiting Gordon's “Critical Legal Histories”

For more than twenty‐five years, Robert Gordon's “Critical Legal Histories” has been savored by legal historians as one of the most incisive explanations available of what legal history can and should be. Gordon's essay, however, is of significance to the course of sociolegal studies in general. This commentary offers an appreciation, and a critique, of “Critical Legal Histories.” It explores Gordon's articulation of the central themes of critical legal studies, in particular his corrosion of functionalism and embrace of the indeterminacy thesis, and assesses the consequences for sociolegal and legal‐historical analysis of the resultant stress on the contingency and complexity of social life.     

Violence against women in video games: a prequel or sequel to rape myth acceptance?

Current research suggests a link between negative attitudes toward women and violence against women, and it also suggests that media may condition such negative attitudes. When considering the tremendous and continued growth of video game sales, and the resulting proliferation of sexual objectification and violence against women in some video games, it is lamentable that there is a dearth of research exploring the effect of such imagery on attitudes toward women. This study is the first study to use actual video game playing and control for causal order, when exploring the effect of sexual exploitation and violence against women in video games on attitudes toward women. By employing a Solomon Four-Group experimental research design, this exploratory study found that a video game depicting sexual objectification of women and violence against women resulted in statistically significant increased rape myths acceptance (rape-supportive attitudes) for male study participants but not for female participants.     

Understanding and influencing the policy process

This essay translates some of the underlying logic of existing research of policy processes into a set of strategies for shaping policy agendas and influencing policy development and change. The argument builds from a synthesized model of the individual and a simplified depiction of the political system. Three overarching strategies are introduced that operate at the policy subsystem level: developing deep knowledge; building networks; and participating for extended periods of time. The essay then considers how a democratic ethic can inform these strategies. Ultimately, the success or failure of influencing the policy process is a matter of odds, but these odds could be changed favorably if individuals employ the three strategies consistently over time. The conclusion contextualizes the arguments and interprets the strategies offered as a meta-theoretical argument of political influence.     

Using the institutional grammar tool to understand regulatory compliance: The case of Colorado aquaculture

What is the relationship between the design of regulations and levels of individual compliance? To answer this question, Crawford and Ostrom's institutional grammar tool is used to deconstruct regulations governing the aquaculture industry in Colorado, USA. Compliance with the deconstructed regulatory components is then assessed based on the perceptions of the appropriateness of the regulations, involvement in designing the regulations, and intrinsic and extrinsic motivations. The findings suggest that levels of compliance with regulations vary across and within individuals regarding various aspects of the regulatory components. As expected, the level of compliance is affected by the perceived appropriateness of regulations, participation in designing the regulations, and feelings of guilt and fear of social disapproval. Furthermore, there is a strong degree of interdependence among the written components, as identified by the institutional grammar tool, in affecting compliance levels. The paper contributes to the regulation and compliance literature by illustrating the utility of the institutional grammar tool in understanding regulatory content, applying a new Q‐Sort technique for measuring individual levels of compliance, and providing a rare exploration into feelings of guilt and fear outside of the laboratory setting.     

Religious perspectives on umbilical cord blood banking

Umbilical cord blood is a valuable source of haematopoietic stem cells. There is little information about whether religious affiliations have any bearing on attitudes to and decisions about its collection, donation and storage. The authors provided information about umbilical cord blood banking to expert commentators from six major world religions (Catholicism, Anglicanism, Islam, Judaism, Hinduism and Buddhism) and asked them to address a specific set of questions in a commentary. The commentaries suggest there is considerable support for umbilical cord blood banking in these religions. Four commentaries provide moral grounds for favouring public donation over private storage. None attach any particular religious significance to the umbilical cord or to the blood within it, nor place restrictions on the ethnicity or religion of donors and recipients. Views on ownership of umbilical cord blood vary. The authors offer a series of general points for those who seek a better understanding of religious perspectives on umbilical cord blood banking.
