Emotional Responses to a Sexual Assault Threat: A Qualitative Analysis Among Women With Histories of Sexual Victimization

Sexual assaults against women are a leading threat to human rights and public health in the United States. Considering the high rates of sexual revictimization among women and the limited understanding of the mechanisms which fuel this phenomenon, the goal of the present study was to investigate the role of emotion in coping with a hypothetical threat of sexual assault for previously sexually victimized college women. A total of 114 college women with a history of sexual victimization listened to an audio-recording describing a sexual assault scenario and then described how they felt. A qualitative analysis paradigm was used to capture participants’ responses in an open-ended, real-time, experiential manner. Data were analyzed using Consensual Qualitative Research—Modified methodology. Four main themes emerged (Negative Reactions, Indifferent Evaluations, Active Responses, and Cognitive Appraisal of the Situation), along with various subcategories, demonstrating the variability of women’s responses to a sexual assault threat. Many women experienced uncomfortable or distressing emotional reactions to the vignette, primarily through discomfort, but also through anger, anxiety, and being upset. Few women reported experiencing fear, and a small number reported experiencing self-blame. The low endorsement of fear and anger in our high-risk sample indicates emotional dysregulation as a potential mechanism of repeated sexual victimization and a promising target for clinical intervention. Overall, results may inform sexual assault risk reduction efforts and the empowerment of women who have experienced sexual victimization

Predictors of Assertive and Nonassertive Styles of Self-Defense Behavior During a Lab-Based Sexual Assault Scenario

The current study examined how psychological factors influence hypothetical behavioral responses to threat (BRTT). College women (n = 113) with a history of sexual victimization completed a standardized lab-based self-defense scenario. Interpersonal skills, coping style, and assertive and non-assertive BRTT during a prior assault predicted assertive BRTT during the task. The use of non-assertive BRTT during past assaults no longer predicted assertive BRTT during the task when accounting for rape acknowledgment. Findings regarding rape acknowledgment demonstrate the complexity of recovery from sexual assault. Our results highlight interpersonal skills as an intervention target for innovative sexual assault risk reduction interventions

Genetic variability in energy balance and pancreatic cancer risk in a population-based case-control study in Minnesota

OBJECTIVES: Accumulating evidence suggests that energy imbalance plays a role in pancreatic carcinogenesis. However, it remains unclear whether single-nucleotide polymorphisms (SNPs) in genes regulating energy homeostasis influence pancreatic cancer risk. We investigated this question in a case-control study conducted from 1994 to 1998. METHODS: Patients (n = 173) were ascertained from hospitals in the Twin Cities and Mayo Clinic, Minnesota. Control subjects (n = 476) were identified from the general population and frequency matched to patients by age and sex. Seven SNPs were evaluated in relation to pancreatic cancer using unconditional logistic regression. RESULTS: After adjustment for confounders, the leucine/proline or proline/proline genotype of the neuropeptide Y (NPY) gene rs16139 was associated with a lower risk than the leucine/leucine genotype (odds ratio, 0.40 [95% confidence interval, 0.15-0.91]). Conversely, an increased risk was observed for the glycine/arginine or arginine/arginine genotype of the adrenoceptor β2, surface (ADRB2) gene rs1042713 as compared with the glycine/glycine genotype (odds ratio, 1.52 [95% confidence interval, 1.01-2.31]). CONCLUSIONS: This study first reveals that SNPs in genes modulating energy intake (NPY) and energy expenditure (ADRB2) altered pancreatic cancer risk. If confirmed by other studies, our findings may shed new light on the etiology and prevention of pancreatic cancer

The Prevalence of Sexual Violence Perpetration in Sexual Minority Men: A Secondary Analysis of Systematic Review Data

Purpose: Prior literature illustrates that sexual minority people (e.g., bisexual, gay, queer) are at increased vulnerability for sexual violence victimization compared to heterosexual peers, including while in college. However, the study of sexual violence perpetration in sexual minority populations, much less specifically sexual minority college men, has been neglected. This article reviews the literature and presents a secondary data analysis of a systematic review on college men’s sexual perpetration rates and associated methodology. We also conducted analyses to summarize available literature regarding publishing dates, authors, and data inclusivity. Methods: We downloaded the dataset and associated materials from Mendeley.com’s data archive. Results: To our surprise, we could not analyze sexual perpetration prevalence rates in sexual minority men using the systematic review data due to absence of reported data across all 77 independent samples including over 5,500 male participants. We found no significant relationship between inclusion of sexual minority men and the use of measurement strategies specialized to assess sexual minority needs. We did find a positive relationship between recency of publication and the inclusion of sexual minority men, r(76) = .24, p = .03, and that most authors/co-authors were women (72%). Conclusions: Preventing perpetration is central to ending sexual violence; therefore, future research should include sexual minority people and use appropriate methodology in the investigation of sexual perpetration characteristics and patterns

Intake of methyl-related nutrients and risk of pancreatic cancer in a population-based case-control study in Minnesota

BACKGROUND/OBJECTIVES: Folate, vitamin B6, vitamin B12, and methionine are involved in DNA synthesis and methylation and thus may modulate pancreatic cancer risk. We investigated these associations in a population-based case-control study conducted in 1994-1998. SUBJECTS/METHODS: Cases (n = 150) were identified from all hospitals in the metropolitan areas of the Twin Cities and the Mayo Clinic, Minnesota. Controls (n = 459) were selected randomly from the general population and were frequency matched to cases by age, sex, and race. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for risk of pancreatic cancer in relation to intake of nutrients considered. RESULTS: Dietary intake of folate was associated with a reduced pancreatic cancer risk [OR (95% CI) for quartile (Q) 4 vs. Q1: 0.31 (0.12-0.78)]. A composite score (range from 2 to 8), reflecting combined dietary intake of folate and vitamin B6, was also inversely associated with pancreatic cancer risk [OR (95% CI) for Q4 vs. Q1: 0.24 (0.08-0.70)]. Null associations were found for intake of vitamin B12 and methionine. CONCLUSIONS: Dietary folate intake was associated with a reduced pancreatic cancer risk, and this association became stronger when dietary intake of folate and vitamin B6 was combined in analysis

The Frequency of Sexual Perpetration in College Men: A Systematic Review of Reported Prevalence Rates from 2000-2017

Background: The prevalence of sexual perpetration in college men is unknown. Prior reviews of sexual violence prevalence rates have produced wide-ranging estimates, likely due to wide variation in measurement strategies. Objectives: This paper systematically reviewed research findings (from 2000-2017) regarding prevalence rates of sexual perpetration in college men and measurement strategies. Data Sources: PsycINFO and Web of Science databases. Eligibility Criteria: Empirical reports published between 2000-2017 that included male participants, available in English, and reported lifetime prevalence findings in Canadian or American college students. Participants: Data from 78 independent samples including 25,524 college men. Results: The average prevalence rate of any sexual perpetration was 29.3% (SD = 16.8), and the average rate of rape was 6.5% (SD = 6.3). Studies that used non-Sexual Experiences Survey (SES) based questionnaires recorded higher prevalence rates (41.5%) than SES-using studies (26.2%). At least sixteen different sexual perpetration questionnaires were identified. Modifying standardized questionnaires was extremely common; this was reported in over half the studies. Studies using modified standardized questionnaires found higher prevalence rates of sexual perpetration than studies using non-modified standardized questionnaires. Limitations: This report focused exclusively on college men in the United States and Canada. Conclusions and Implications: On average, 29% of college males report engaging in behaviors defined as sexual perpetration; however, there was a strong influence of measurement strategy on reported rates

New g'r'i'z' Photometry of the NGC 5128 Globular Cluster System

We present new photometry for 323 of the globular clusters in NGC 5128 (Centaurus A), measured for the first time in the $g'r'i'z'$ filter system. The color indices are calibrated directly to standard stars in the $g'r'i'z'$ system and are used to establish the fiducial mean colors for the blue and red (low and high metallicity) globular cluster sequences. We also use spectroscopically measured abundances to establish the conversion between the most metallicity-sensitive colors ($(g'-r')_0$, $(g'-i')_0$) and metallicity, [Fe/H].Comment: 14 pages, 9 figures, accepted in A
