An Experimental Assessment of Third Parties as Potential Guardians: Victim Gender, Conflict, and Individual Perceptions of Social Situations.

The guardianship component of routine activity theory (RAT) remains underexamined. Recent research has emphasized "guardianship-in-action," or the processes by which individuals evaluate potentially problematic situations. Research has also begun to identify conditions conducive to bystander intervention in troublesome situations, but has not been incorporated into the emerging literature on guardianship-in-action. The current study integrates these literatures to understand how individuals perceive problematic social situations by examining how victims' gender influences guardians' perceptions of social situations and willingness to intervene across conflicts. Using an experimental vignette design, and a sample of 370 American adults, respondents were randomly assigned to vignettes involving verbal and physical conflicts between two men or a man and a woman. A series of t tests, chi-square tests, and McNemar's tests assessed mean differences in respondent perceptions. Situations in which victims are female were perceived as being more serious and requiring intervention. Situations involving interpersonal physical violence similarly elicit stronger concerns, and a greater willingness to intervene, from potential guardians. Theory and policy implications are discussed.

Structuring the Invisible War: Base and Community Influences on Military Sexual Assault Occurrence.

INTRODUCTION: This study examined the relationship between military sexual assault and structural factors including base (e.g., base density) and community (e.g., economic deprivation) characteristics. METHODS: Data on military sexual assault against men and women for fiscal years 2013-2016 were drawn from Sexual Assault Prevention and Response Office's 2017 report, "Sexual Assault Received at Military Installations and Combat Areas of Interest." Base information was pulled from fiscal years 2012 and 2013 Department of Defense's Base Structure Reports. Community-level information was drawn from 5-year American Community Survey estimates (2008-2012). Analyses were conducted in 2019. Negative binomial models were used to examine predictors of military sexual assault. RESULTS: Compared with civilian personnel, higher concentrations of military personnel on bases increased military sexual assault (incident rate ratio=1.01, p=0.025). Compared with Air Force-controlled installations, Navy and Marine bases were associated with higher military sexual assault prevalence (incident rate ratio=2.22, p<0.001; incident rate ratio=2.38, p<0.001, respectively). Community economic disadvantage was inversely related to military sexual assault (incident rate ratio=0.69, p=0.001), whereas residential mobility (incident rate ratio=1.07, p=0.002), percentage of racial/ethnic minorities (incident rate ratio=1.02, p=0.024 black; incident rate ratio=1.03, p<0.001 Hispanic), and percentage of residents who are veterans (incident rate ratio=1.13, p<0.001) were positively related to military sexual assault. CONCLUSIONS: Military sexual assault prevalence is associated with the structural characteristics of military installations and characteristics of the communities in which these installations are located. Findings suggest that further research on structural predictors of military sexual assault is needed and prevention programs and services may benefit from more community engagement.

Bacterial screening of platelet components by National Health Service Blood and Transplant, an effective risk reduction measure.

BACKGROUND: Bacterial contamination of blood components remains a major cause of sepsis in transfusion medicine. Between 2006 and 2010 in the 5 years before the introduction of bacterial screening of platelet (PLT) components by National Health Service Blood and Transplant (NHSBT), seven cases of PLT component-associated transmission of bacterial infection were recorded for 10 patients, three of which were fatal. STUDY DESIGN AND METHODS: Sampling of individual PLT components was undertaken at 36 to 48 hours after donation and tested in the BacT/ALERT system with 8 mL inoculated into each of aerobic and anaerobic culture bottles. Bottles were incubated until the end of the 7-day shelf life and initial reactive bottles were examined for contamination. Bacterial screened time-expired PLTs were tested as in the screen method. RESULTS: From February 2011 to September 2015, a total of 1,239,029 PLT components were screened. Initial-reactive, confirmed-positive, and false-positive rates were 0.37, 0.03, and 0.19%, respectively. False-negative cultures, all with Staphylococcus aureus, occurred on four occasions; three were visually detected before transfusion and one confirmed transmission resulted in patient morbidity. The NHSBT screening protocol effectively reduced the number of clinically adverse transfusion transmissions by 90% in this reporting period, compared to a similar time period before implementation. Delayed testing of 4515 time-expired PLT units after screening revealed no positives. CONCLUSION: The implementation of bacterial screening of PLT components with the NHSBT BacT/ALERT protocol was an effective risk reduction measure and increased the safety of the blood supply.

An experimental investigation into perceptions of disrespect during interpersonal conflict.

Perceptions of disrespect are central to everyday life. Despite the importance of disrespect across various social arenas, prior research has failed to empirically examine the factors influencing these perceptions. This problem is magnified when considering that perceptions or disrespect may vary across individuals and social situations alike. Drawing from theories of social geometry and symbolic interaction, this study examines the individual and situational characteristics that inform perceptions of disrespect. Using factorial vignettes, and a large sample of students, respondents were asked to assess actors in various conflicts. Results from a series of hierarchical linear models show that perceptions of disrespect vary across individuals. The content of situations appears to drive perceptions of disrespect more than individual characteristics. Implications for future research on disrespect are discussed.

From 'What the F#@% is a Facebook?' to 'Who Doesn't Use Facebook?': The role of criminal lifestyles in the adoption and use of the Internet.

Concerns about a digital divide persist and recent calls have been made for understanding how lifestyles influence Internet adoption and use. Online criminal behaviors have drawn attention from law enforcement, but diffusion of innovation theory suggests higher propensities for crime, particularly street crime, reduces the likelihood of Internet use. Drawing from this theory and research on the role of street criminal lifestyles on technology adoption, this study examined patterns of Internet use among a sample of 585 individuals at-risk for and involved in street crime. Results from our logistic and negative binomial regression analyses lead to two general conclusions: (1) compared to research on the general population, similar predictors and lower rates of Internet participation and usage are observed, and (2) mixed evidence suggests participation in criminal lifestyles contributes to digital inequality. The results support a theory of technological diffusion to marginalized populations. We conclude by discussing the expansion of technology, digital inequality, and crime.
