Who Are the Mavens of Bystander Intervention? Implications for the Social Diffusion of Intervention Norms

A recent randomized controlled trial reported that Green Dot (GD)—a bystander intervention training program that targets popular opinion leaders for intensive training—reduced school-level interpersonal violence perpetration and victimization. Expanding GD’s targeted group members to include “mavens” of bystander intervention—those who spread bystander intervention norms to others by communicating with peers—may increase the effectiveness of such training. Self-report data collected from students at the 13 intervention high schools in Kentucky are analyzed to identify characteristics of those who engage in discussions with peers about preventing interpersonal violence. Findings show that students who engage in more frequent bystander behaviors are more likely to have such conversations with peers, but GD participants were no more likely than nonparticipants to discuss preventing interpersonal violence with peers

Less Safe in the Ivory Tower: Campus Sexual Assault Policy in the Trump Administration

Since the late 20th century, the federal government has regulated colleges’ and universities’ handling of campus sexual and gender-based violence (CSGBV). Although the arc of history has bent toward establishing greater protections for victims of such violence, new proposed regulation by the U.S. Department of Education under the Trump administration focuses more heavily on ensuring due process rights for students accused of CSGBV. Most recently, in November 2018, U.S. Secretary of Education, Betsy DeVos submitted a proposed rule change to the regulation of Title IX of the Education Amendments of 1972. This article provides the historical context for this most recent proposed federal regulation of CSGBV and discusses the criticism of this proposal that, if it is implemented, students would become less safe in the ivory tower

The Application of Bystander Intervention Scripts: Implications for Guardianship in Action

Responding to high rates of interpersonal victimization and perpetration among adolescents, schools have implemented bystander intervention (BI) training to educate students to intervene to prevent or stop violence. These trainings function much like an application of scripts for guardianship in action. The current study builds on the overlapping and complementary bodies of BI and routine activities research by testing whether participation in BI training, namely Green Dot (GD), influences individuals’ underlying ability to intervene. Using four years of survey data collected from high school students (N = 2,374–3,443), we use item response theory to model the difficulty of engaging in different BI behaviors. We then estimate multivariate ordinary least squares regression models, one for each year, to estimate the effect of GD training on students’ ability to intervene. The item response theory results show that BI behaviors differ in terms of how “difficult” they are for respondents to engage in. Findings show that in each year, GD training increased students’ underlying ability to intervene. Our findings suggest BI training and guardianship in action scripts should take into account this varying difficulty of intervention behaviors to best train individuals for successful intervention to prevent victimization

Does Change in Binge Drinking Reduce Risk of Repeat Sexual Assault Victimization? Evidence From Three Cohorts of Freshman Undergraduate Women

Many college students who experience sexual assault experience subsequent (i.e., repeat) sexual assault incidents. There is also an established relationship between sexual assault and binge drinking. The “once bitten, twice shy” (OBTS) hypothesis suggests that those who experience alcohol- or drugrelated (AOD) sexual assault would reduce how frequently they binge drink in an effort to avoid repeat victimization. We test this hypothesis by analyzing two years of survey data collected from a panel of three cohorts of freshmen women. Supportive of OBTS, our analyses reveal that students who experienced an AOD-related sexual assault at time 1 only reduced the number of days they binge drank from time 1 to time 2 and that this change significantly differed from repeat victims. Implications for efforts to reduce sexual victimization against college women are discussed

A New Frontier: The Development and Validation of the Intimate Partner Cyber Abuse Instrument

As technology advances, new opportunities for partners to gain power and control in their romantic relationships are readily available. New cyber-based behaviors have slowly garnered scholarly attention, but measurement-related issues have not. We take the logical next steps to (1) develop and validate a comprehensive measure of intimate partner cyber abuse (IPCA) for adults using classical test theory and item response theory and (2) estimate IPCA prevalence rate for a range of relationship types. A sample of 1,500 adults, currently in an intimate partner relationship, 18 years or older, and living in the United States, completed an online questionnaire about their IPCA experiences within the 6 months prior. Two parameter logistic modeling and confirmatory factor analyses revealed a five-dimensional structure: cyber direct aggression, cyber sexual coercion, cyber financial control, cyber control, and cyber monitoring, with 14.85% of the sample experiencing at least one dimension. These IPCA dimensions were examined for differential functioning across gender identity, race, student status, and relationship type. Collectively, the findings have implications for IPCA measurement and related research, including theoretically derived hypotheses whose findings can inform prevention

Examining the Effect of Perceived Responsibility on Online Bystander Intervention, Target Hardening, and Inaction

Failure to take responsibility for intervening has been identified as a primary barrier to bystander intervention. Building on these findings, we examine how perceptions of responsibility affect responses to witnessing victimization in the online realm—a topic that has received limited attention. Using a maximum-likelihood selection model, we analyze data from the Pew American Trends Panel (N = 3709) to estimate the effects of respondents’ perceptions of the role different groups should play in addressing online harassment on their likelihood to engage in intervention, target hardening, or inaction in response to witnessing online harassment, conditioned upon their likelihood of having witnessed such behavior. Findings indicate that the greater role respondents believe online users should have in addressing online harassment, the more likely they are to intervene. (b = .310). The greater role respondents believe law enforcement or elected officials should have in addressing online harassment, the less likely they are to intervene (b = −.135 and −.072, respectively). These findings have implications for future efforts to curb online harassment through users’ crime prevention efforts

Change Matters: Binge Drinking and Drugging Victimization over Time in Three College Freshman Cohorts

The “once bitten, twice shy” (OBTS) hypothesis argues that crime victims who change their involvement in risky lifestyle behaviors reduce their likelihood of experiencing repeat victimization. Tests of this hypothesis have yielded weak to mixed results, which may be due to methodological issues. We address these methodological issues by testing the OBTS hypothesis for repeat drugging victimization with survey data from a panel of three freshman cohorts at three large, public universities. Supportive of the OBTS hypothesis, the multivariate results show that, on average, those not drugged at Time 1 or Time 2 and those drugged at Time 1 and Time 2 increased the number of days they binge drank in the past month significantly more than those who were drugged at Time 1 only. Our findings have implications for both victimology theory and drugging prevention programming

Mechanism of action of VP1-001 in cryAB(R120G)-associated and age-related cataracts

PurposeWe previously identified an oxysterol, VP1-001 (also known as compound 29), that partially restores the transparency of lenses with cataracts. To understand the mechanism of VP1-001, we tested the ability of its enantiomer, ent-VP1-001, to bind and stabilize αB-crystallin (cryAB) in vitro and to produce a similar therapeutic effect in cryAB(R120G) mutant and aged wild-type mice with cataracts. VP1-001 and ent-VP1-001 have identical physicochemical properties. These experiments are designed to critically evaluate whether stereoselective binding to cryAB is required for activity.MethodsWe compared the binding of VP1-001 and ent-VP1-001 to cryAB using in silico docking, differential scanning fluorimetry (DSF), and microscale thermophoresis (MST). Compounds were delivered by six topical administrations to mouse eyes over 2 weeks, and the effects on cataracts and lens refractive measures in vivo were examined. Additionally, lens epithelial and fiber cell morphologies were assessed via transmission electron microscopy.ResultsDocking studies suggested greater binding of VP1-001 into a deep groove in the cryAB dimer compared with ent-VP1-001. Consistent with this prediction, DSF and MST experiments showed that VP1-001 bound cryAB, whereas ent-VP1-001 did not. Accordingly, topical treatment of lenses with ent-VP1-001 had no effect, whereas VP1-001 produced a statistically significant improvement in lens clarity and favorable changes in lens morphology.ConclusionsThe ability of VP1-001 to bind native cryAB dimers is important for its ability to reverse lens opacity in mouse models of cataracts
