Women\u27s risk perception and sexual victimization: A review of the literature

This article reviews empirical and theoretical studies that examined the relationship between risk perception and sexual victimization in women. Studies examining women\u27s general perceptions of risk for sexual assault as well as their ability to identify and respond to threat in specific situations are reviewed. Theoretical discussions of the optimistic bias and cognitive–ecological models of risk recognition are discussed in order to account for findings in the literature. Implications for interventions with women as well as recommendations for future research are provided

Risk and protective factors for sexual aggression across the ecosystem: An overview

Prevention of sexual aggression (which ranges from perpetration of unwanted sexual contact to attempted/completed rape) is a complex public health and safety issue that requires attention to multiple levels of social ecology (Centers for Disease Control and Prevention, 2004). The social ecological model provides a framework for understanding how risk and protective factors for sexual aggression exist at multiple levels, with some factors being more proximal such as the individual attitudes, and other factors being more distal such as the broader culture (e.g., laws and policies) (Centers for Disease Control and Prevention, 2013). Indeed, research indicates a variety of risk factors (factors associated with increased risk for sexual aggression) and protective factors (factors associated with decreased risk for sexual aggression) that exist across the social ecology (Basile et al., 2016; Tharp et al., 2013). Understanding risk and protective factors across multiple levels of the ecology is key to preventing the complex behavior of sexual aggression. In the current chapter, we review risk and protective factors for sexual aggression among men and boys at multiple levels of the social ecology. Of note, although we earnestly reviewed the interdisciplinary research, this chapter is not meant to be a systematic review. Rather, the purpose of this chapter is to discuss various levels of the social ecology and provide examples of risk and protective factors for the perpetration of sexual assault within each of these levels. The foundational information provided in this chapter sets the stage for subsequent chapters in this edition that focuses on strategies for the primary prevention of sexual aggression

Youth perceptions of prevention norms and peer violence perpetration and victimization: A prospective analysis

The purpose of the current study is to prospectively examine the extent to which social norms perceptions regarding commitment to ending sexual violence are associated with subsequent peer victimization and perpetration experiences. Two types of social norms perceptions were examined: 1) peer norms (perceptions of norms among other students in their city), and 2) adult norms (perceptions of norms among adults in their city). Participants were 1259 middle and high school youth from a single school district (three high schools and five middle schools) who completed online surveys at two‐time points, 6 months apart. Adolescents for whom perceptions of peer norms were one standard deviation or more above and below the mean of actual norms were “over‐perceivers” and “under‐perceivers,” respectively. Overperceivers overestimated their peers’ commitment to ending sexual violence, whereas underperceivers underestimated their peers’ commitment to ending sexual violence. Other adolescents were “accurate perceivers”; these adolescents were accurate in their estimation of their peers’ commitment to ending sexual violence. In general, underperceivers (22.2% of the sample) were more likely than accurate perceivers (77.8% of the sample) to subsequently experience peer‐to‐peer perpetration and victimization. Adolescents who perceived adults to have a higher commitment to ending sexual violence were less likely to report subsequent perpetration and victimization for some forms of peer-to‐peer violence. These findings highlight the potential promise of the social norms approaches to prevent peer‐to‐peer violence among youth which aligns with increasing calls in the field to integrate these approaches into comprehensive sexual violence prevention

Alexithymia and caffeine: The role of caffeine expectancies and craving

Alexithymia refers to difficulties in identifying and describing feelings and is often associated with problematic substance use for a variety of substances. A recent study investigating the relationship between alexithymia and caffeine use found that university students with alexithymia reported typically consuming nearly twice as much caffeine as those without alexithymia. The current study assessed the potential role of caffeine expectancies and craving in mediating this relationship. University students (n = 104) aged 18–30 years, who regularly consumed both caffeine and alcohol, completed the following measures: a demographic questionnaire, Toronto Alexithymia Scale-20 (TAS-20), Beck Anxiety Inventory, Caffeine Expectancy Questionnaire (CaffEQ), Caffeine Consumption Questionnaire, Sensitivity to Punishment and Sensitivity to Reward Questionnaire, and the Alcohol Use Disorders Identification Test. Hierarchical regression and path analyses indicated that caffeine expectancies and caffeine craving mediated the relationship between alexithymia and caffeine consumption. Given that alexithymia is common in samples of clients undergoing treatment for substance dependence for a variety of substances, alexithymia appears to be associated with increased susceptibility to drug cravings—even for a drug as mild in its typical effects as caffeine

Using intergenerational photovoice to understand family strengths among Native American children and their caregivers

The purpose of the current study was to examine Native American children and caregivers\u27 perspectives of family and cultural strengths using photovoice and to identify lessons learned from the first‐ever implementation of intergenerational photovoice with Native Americans. Participants were Native American, low‐income caregivers (n = 6) and their children (n = 12) between the ages of 10 and 15 who participated in six photovoice sessions. The themes that emerged from photos and group discussion included myriad challenges faced by Native American families including exposure to community violence, substance abuse, and criminal offending and incarceration. Themes also emerged that highlighted the strengths of Native families that were used to overcome identified challenges, including religion/spirituality, engagement in traditional cultural practices (e.g., prayer, song, dance), healthy activities (e.g., running, meditation). These data provided foundational information that is currently being used, along with other data, to develop a culturally grounded, strengths-focused, family‐based program (Tiwahe Wicagwicayapi [Strengthening/Growing Families in Lakota]) to prevent adverse childhood experiences. We also discuss the challenges of intergenerational photovoice and lessons learned to inform future intergenerational photovoice projects

College students’ perceptions of alcohol’s role in disclosures of sexual assault and intimate partner violence

Objective: Much is known about how alcohol increases the risk of sexual assault or intimate partner violence victimization during college. This research qualitatively explores perceptions about how alcohol influences disclosures about these events to informal supports. Participants: Participants included college students who received a disclosure wherein they or the survivor were drinking during the disclosure (n = 81). Methods: Responses were coded with regard to who was drinking and whether the effect of drinking during the disclosure was perceived as positive, negative, mixed, or neutral/none. Results: Participants perceived alcohol to have both positive (e.g., increasing the likelihood of discussing difficult topics) and negative (e.g., cognitive impairment increased negative emotions) effects on disclosures. Conclusion: Prevention and intervention efforts should identify targeted strategies (e.g., remembering one or two easy and helpful phrases; revisiting the topic again while sober) to help survivors and disclosure recipients have constructive conversations in the presence of alcohol

Understanding and mitigating thiaminase activity in silver carp

A deficiency of thiamine (vitamin B1), an essential cofactor for enzymes involved in metabolic processes, can be caused by the enzyme thiaminase. Thiaminase in food stocks has been linked to morbidity and mortality due to thiamine depletion in many ecologically and economically important species. Thiaminase activity has been detected in certain bacteria, plants, and fish species, including carp. The invasive silver carp (Hypophthalmichthys molitrix) presents an enormous burden to ecosystems throughout the Mississippi River watershed. Its large biomass and nutritional content offer an attractive possibility as a food source for humans, wild animals, or pets. Additionally, harvesting this fish could alleviate some of the effects of this species on waterways. However, the presence of thiaminase would detract from its value for dietary consumption. Here we confirm the presence of thiaminase in several tissues from silver carp, most notably the viscera, and systematically examine the effects of microwaving, baking, dehydrating, and freeze-drying on thiaminase activity. Certain temperatures and durations of baking and microwaving reduced thiaminase activity to undetectable levels. However, caution should be taken when carp tissue is concentrated by processes without sufficient heat treatment, such as freeze-drying or dehydration, which results in concentration, but not inactivation of the enzyme. The effects of such treatments on the ease of extracting proteins, including thiaminase, and the impact on data interpretation using the 4-nitrothiophenol (4-NTP) thiaminase assay were considered

Ophthalmic and clinical factors that predict four-year development and worsening of diabetic retinopathy in type 1 diabetes

To investigate the role of ophthalmic imaging markers - namely retinal thickness measures and corneal nerve morphology - in predicting four-year development and worsening of diabetic retinopathy (DR) in type 1 diabetes (T1DM).126 eyes of 126 participants with T1DM were examined at baseline and after four years. Diabetic retinopathy (DR) was graded using the Early Treatment Diabetic Retinopathy Study scale. HbA1c, nephropathy, neuropathy, cardiovascular factors, and retinal thickness using optical coherence tomography (OCT) and corneal nerve fiber length (CNFL) using corneal confocal microscopy at baseline were assessed by univariate and step-wise multiple logistic regression, and their diagnostic capabilities for single and combined measures.Four-year development of DR was 19% (13 of 68 without DR at baseline). Worsening of DR was seen in 43% (25 of 58 with DR at baseline). When adjusted for potential confounders, a lower CNFL (AUC=0.637, p=0.040, 64% sensitivity and 64% specificity at 14.9mm/mm(2) cut-off), higher triglycerides (AUC=0.669, p=0.012, 64% sensitivity, 62% specificity at 0.85mmol/L) and an elevated vibration threshold (AUC=0.708, p=0.002, 96% sensitivity, 40% specificity at 3.55Hz) were significant predictors for four-year worsening of DR.Reduced CNFL, elevated vibration perception threshold and higher triglycerides can predict future worsening of DR
