Agreement on intimate partner violence among a sample of blue-collar couples

This study assessed agreement level about the occurrence of past-year male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) among a sample of 897 blue-collar couples. Intimate partner violence (IPV) was measured with the Physical Assault subscale of the revised Conflict Tactics Scales (CTS2). Agreement level was assessed with Cohen's kappa statistic. Lower-bound estimates (based on couple agreement that an IPV event occurred) and upper-bound estimates (based on uncorroborated reports from either partner that an IPV event occurred) were calculated. Results indicated low agreement for most IPV behaviors (kappa < .40). Estimated lower- and upper-bound rates for MFPV were 6.7% and 21.2%, for FMPV, 7.1% and 24.2%, and for any IPV, 10.1% and 30.2%. Findings suggest that single-point IPV prevalence estimates are biased; lower- and upper-bound estimates using collateral reports should be calculated when possible. In addition, findings underscore the importance of conducting IPV research among understudied populations, such as working-class couples, that may be at elevated IPV risk.     

The public sector and co-creation in turbulent times: A systematic literature review on robust governance in the COVID-19 emergency

The capacity of public sector of co-creating with other stakeholders is challenged by the increasing presence of disruptive turbulent events, such as the COVID-19. At this regard, robustness has been identified as a suitable response to deal with this kind of events. Through a systematic literature review, we analyzed how public sector organizations have co-created with other actors during the COVID-19 and what have been the contribution of robust governance strategies. Our findings point firstly to the empirical validity of the robustness concept, providing evidence of the extensive use of robust governance strategies into the co-creation processes. Second, we identified a configurational approach to robustness, with governments co-creating by simultaneously employing several robust strategies. Thirdly, we observed a more active involvement of societal stakeholders, with emergence of proto-institutions and potential threats to the political system.     

Performing Regulation: Transcending Regulatory Ritualism in HIV Clinics

Sociolegal scholars suggest that regulatory encounters often are occasions for displaying a surface compliance decoupled from day‐to‐day practice. Yet ethnographic data from five highly regulated HIV clinics show that regulatory encounters open opportunities both for ritualism and—surprisingly—for transcending ritualism. Using a theatrical analogy, we argue that improv performance is the technology that enables regulatory inspectors and clinic staff to transcend ritualism. As regulatory encounters unfold, clinics' carefully prepared performances sometimes change into more cooperative interactions where inspectors and regulatees hash out details about how rules will be applied and even work together on reports for the regulators' supervisors. By “performing together,” regulatory inspectors gain access to the clinic's backstage where they can assess clinic workers' deeper conformity to ethical and scientific norms. But such joint performances are less likely where cultural divides and material scarcity make it difficult for clinic staff to gain inspectors' trust.     

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.     

Violence and Mental Illness: A New Analytic Approach

Empirical studies of violence and mental illness have used many different methods. Current state-of-the-art methods gather information from both subject and collateral interviews as well as official records. Typically these sources are treated as additive. Any report of a violent incident from any source is treated as true and all reported incidents are added to generate estimates of frequency. This paper presents a new statistical technique that uses the level of agreement between the sources of data to adjust those estimates. The evidence suggests that, although the additive technique for using multiple sources correctly estimates how many people are involved, it substantially underestimates the number of incidents. The new technique substantially reduces both false negatives and false positives.
