Victimization, Disability Status, and Fear Among U.S. College Students

Levels of fear of crime are high in the United States, though they differ across groups. Researchers have identified characteristics associated with high levels of fear of crime, often noting that those most fearful also have vulnerabilities that increase their risk of experiencing victimization. Thus, having a vulnerability and experiencing victimization may exacerbate fear of crime. One such characteristic that may impact fear of crime is having a disability. The current study uses data from the American College Health Association's National College Health Assessment Spring 2021 survey to investigate how disability interacts with victimization to impact fear of crime among college students. To do so, assessments of personal safety in multiple contexts are used: at night, during the day, on campus, and in the community. Results show that disability increases the odds of feeling unsafe across contexts, as does having a history of victimization. Nonetheless, disability does not significantly interact with victimization. It may be that having a disability is such a strong risk factor for feeling unsafe that being a victim does not significantly further increase this assessment. Institutions of higher learning should use their offices of accommodation as well as victim services to assist students in reducing their feelings of being unsafe.

Examining Risk Factors of Intimate Partner Violence Victimization in Central America: A Snapshot of Guatemala and Honduras

The current study examines country-specific risk factors of intimate partner violence (IPV) victimization among Guatemalan and Honduran women. More specifically, we examine if (in)equality between partners, experience of controlling or emotionally abusive behavior, and components of the intergenerational transmission of violence significantly affect the risk of lifetime IPV victimization for Guatemalan (N = 5,645) and Honduran women (N = 9,427). We address this by analyzing both the 2014 to 2015 Guatemala Demographic and Health Survey and the 2011 to 2012 Honduras Demographic and Health Survey. Results suggest that equality between partners operates differently across the two nations, which is likely related to social norms in each country. In particular, having more decisional input is a protective factor against IPV victimization for Guatemalan women. Increased educational attainment, however, is a risk factor for IPV victimization among Honduran women. Implications, especially as they pertain to social service agencies and programming, are discussed.

Extending the Shadow of Sexual Assault Hypothesis: Fear of Sexual Violence and Hate Crimes among Lesbian, Gay, Bisexual, and Transgender Persons

Women's fear has been explained as rooted in fears of sexual assault-a phenomenon known as the shadow of sexual assault hypothesis. The current study extends this hypothesis to examine whether lesbian, gay, bisexual, and transgender persons' fear of hate crimes is shadowed by fears of sexual assault. Results indicate that bisexual and transgender persons express greater fear of hate crimes relative to others. This fear is explained by their fear of sexual assault-supporting the shadow hypothesis for bisexual and transgender persons. Findings suggest the importance of fear of sexual assault in explaining sexual and gender minorities' fear of hate crimes.

"When Can I Call Home?" Coercive Control, Structural Isolation, and Functional Isolation Among Attendees of Residential Behavioral Modification Programs

The "Troubled Teen Industry" refers to a network of federally unregulated programs marketed toward the behavior modification of teens through therapeutic intervention and elite education. The true nature and structure of these programs, however, remains relatively unstudied, with the consequences of program attendance largely unknown or based on anecdotal evidence. This study systematically analyzes 77 open-source testimonials of former program attendees for themes of coercive control and isolation. Thematic analyses revealed high rates of coercive control within these narratives. In total, 66 narratives mentioned themes associated with coercive control that were unrelated to isolation. Specifically, respondents experienced frequent psychological abuse, gaslighting, humiliation, and name calling. Additionally, a total of 69 narratives contained themes of coercive control specific to functional or structural isolation. The lack of privacy combined with fear of staff retaliation for disobedience lead to structural and functional isolation among program attendees, preventing program attendees from engaging in help-seeking behaviors. Study results provide critical information as to the functioning of these programs, the experiences of youth involved with these programs, and how youth involved may be affected. Such findings justify the dedication of resources to further research this population and encourages the development of federal policy regarding the functioning of these institutions.

A Systematic Review of Lifestyle-Routine Activity Theory in the Context of Direct-Contact Sexual Victimization

Studies have extended and applied lifestyle-routine activity theory (L-RAT) to direct-contact sexual violence (SV). Yet, operationalizations of theoretical concepts-exposure, proximity, target suitability, and guardianship-have not been consistent across studies within this context, and therefore the ultimate conclusions on the robustness of the theory remain an open empirical question. In this systematic review, we compile scholarship on the application of L-RAT to direct-contact SV to identify how core concepts have been operationalized as well as their association with SV. Studies met the inclusion criteria if they were published before February 2022, examined direct-contact sexual victimization, and explicitly categorized measures into one of the aforementioned theoretical concepts. Overall, 24 studies met the inclusion criteria. Certain factors, such as alcohol and substance use as well as sex behaviors, emerged as consistent operationalizations of exposure, proximity, target suitability, and guardianship across studies. Alcohol and substance use, sexual orientation, relationship status, and behavioral health conditions were common correlates of SV. Nevertheless, there was considerable variability in measurement and significance, clouding how these factors affect risk of SV. In addition, several operationalizations were unique to single studies, reflecting context-specific operationalizations about the population and research question at hand. Conclusions drawn from this work have implications for the generalizability of the body of knowledge related to the application of L-RAT to SV and identify the need for systematic replication efforts. Implications for future research, especially as it relates to replication efforts and claims around generalizability, are discussed.

Assessment of Functional and Dysfunctional Perceived Threat of Hate Crimes Among Persons With and Without Disability

This study examined the relationship between disability status and perceived threat of hate crimes. Building on existing conceptual frameworks, first we differentiated between dysfunctional perceived threat that damages quality of life and functional perceived threat that has the capacity to be motivational and precautionary. We then examined how disability status predicts individuals' threat memberships across dysfunctional and functional perceived threats of hate crimes. Results-based on a survey of 1,824 adults recruited from Amazon's Mechanical Turk-indicate that persons with a disability are more likely than those without a disability to exhibit dysfunctional perceived threat (vs. functional or no perceived threat) of hate crime across different bias motivations. This relationship was evident even when accounting for those most at risk for each type of hate crime (e.g., persons of color for anti-race/ethnicity hate crime). Further, persons with cognitive and physical disabilities were associated with higher odds of dysfunctional perceived threat of all types of hate crimes when compared to persons without a disability. Overall, the present study highlights that persons with a disability may experience exacerbated consequences of subjective threat of hate crimes. Findings also suggest the importance of an intersectional approach to hate crime by considering how disability may intersect with other forms of oppression in relation to perceived threat of hate crime. Implications and future directions, especially as they relate to measurement, are discussed.

Reproductive Coercion Among College Students: An Extension and Test of Routine Activity Theory

The current study is guided by routine activity theory to explore the risk of experiencing reproductive coercion among a sample of sexually active college students (N = 1,515). Findings indicate that being in an exclusive relationship was associated with lower odds of reproductive coercion, yet prior victimization, including emotional abuse and sexual violence, was associated with higher odds of reproductive coercion. This study supports other research that finds reproductive coercion does not occur in isolation from other victimization experiences, and multifaceted prevention strategies are needed. Implications relating to autonomous reproductive decision-making are discussed.

Factors Associated with Stalking Duration Among a Nationally Representative Sample: Results from the 2010 National Intimate Partner and Sexual Violence Survey

The current study examined the duration of stalking episodes among a nationally representative sample. Analyses of the National Intimate Partner and Sexual Violence Survey estimated if the victim-perpetrator relationship and other types of victimization experienced were associated with (a) if the stalking episode lasted over a year (N = 1,509) and (b) the length of stalking episodes, in days, for episodes <1 year (N = 506). Findings indicate coercive control was associated with higher odds the stalking episode lasted over a year and increased the length of episodes lasting <1 year. The intersection of stalking and coercive control is discussed.

Understanding College Students' Perceived Help-Seeking Knowledge and Awareness about Sexual Misconduct Policies and Procedures

Institutions of higher education have attempted to respond to students' experiences of sexual victimization by developing resources and processes for addressing sexual misconduct. However, extant research suggests that students rarely use campus-based resources and many students lack knowledge about campus services and the processes that institutions of higher education take to respond to sexual misconduct. This study uses data from a campus climate survey at one midsized southeast university to examine students' perceived and actual knowledge about help-seeking and policies and procedures (i.e., mandatory reporting, investigation mandates, confidential resources, accommodations for survivors) at their university. Additionally, we explore gaps in their knowledge of these measures (N = 2261). We also consider the factors that predict these outcomes. On average, students report moderate perceived knowledge about help-seeking on campus. However, roughly 67% did not have a fully comprehensive and accurate understanding of policies and procedures to address sexual misconduct at the university. These findings are problematic, as institutions of higher education rely on survivors coming forward to report their experiences and participate in investigative processes when detecting and elevating complaints. We highlight implications for institutions of higher education.

A Systematic Review of the Biological Correlates and Consequences of Childhood Maltreatment and Adverse Childhood Experiences

Childhood maltreatment (CM) and adverse childhood experiences (ACEs) are two primary forms of interpersonal victimization that have been associated with a host of deleterious health outcomes. Studies over the past decade have begun to use a range of biologically informed methods to better understand the role biology plays in the relationship between CM, ACEs, and later life outcomes. This line of research has shown that both forms of victimization occur at sensitive periods of development, which can increase the likelihood of "getting under the skin" and influence health and behavior across the life course. This review examines the current state of knowledge on this hypothesis. One hundred and ninety-nine studies are included in this systematic review based on criteria that they be written in English, use a biologically informed method, and be conducted on samples of humans. Results reveal that latent additive genetic influences, biological system functioning captured by biomarkers, polygenic risk scores, and neurobiological factors are commonly associated with exposure and response to CM and ACEs. The implication of these findings for the existing body of research on early life victimization and recommendations for future research and policy are discussed.

Association Between Disabilities, Educational Attainment, Literacy, and Intimate Partner Violence: Findings from the Indian National Family Health Surveys

Intimate partner violence (IPV) is widespread across the Global South, including India, due to cultural and patriarchal norms that encourage and facilitate such behaviors. These include age at marriage, community- and individual-level encouragement of IPV, and limited access to education across the Global South, particularly for women. Despite this, little research has sought to disentangle the role that disabilities play in affecting women's risk of IPV in India. The current study analyzes a sample of currently married women (N = 114,901) from the nationally representative 2015-2016 and 2019-2021 National Family Health Surveys (NFHS) to assess whether a relationship exists between these dimensions, while controlling for well-known IPV correlates, with physical IPV and controlling behaviors. Logistic regression analyses revealed that persons with cognitive/intellectual disabilities as well as blind respondents were more likely to experience physical IPV. Blind respondents were also more likely to experience controlling behavior. Further, findings indicate that those with no or some education were more likely to experience physical IPV relative to those with higher education. Findings from the current study demonstrate the need for IPV reduction policies to ensure that adequate accommodations are available to facilitate help-seeking behaviors among persons with disabilities. Tailored prevention policies are also needed which consider both context- and location-specific factors associated with risk.

Child Marriage and Intimate Partner Violence: An Examination of Individual, Community, and National Factors

Despite being a human rights violation, child marriage still takes place across the globe. Prior scholarship has shown early marriage to be associated with an increased risk of intimate partner violence (IPV). Drawing on data from the nationally representative Demographic and Health Surveys-conducted in developing and transitional nations where rates of child marriage tend to be higher-the current study provides a cross-national examination of individual-, community-, and national-level predictors of child marriage and their association with physical and emotional IPV. The sample of ever married women includes 281,674 respondents across 46 developing and transitional nations. Findings reveal the prevalence of child marriage was largely consistent with worldwide estimates. Over half of the sample (59.97%) were over the age of 18 when they married and about 1 in 10 women were married at age 14 or younger. A later age at marriage, measured continuously, was associated with lower odds of physical and emotional IPV. When considering the 18 and over cutoff traditionally used to operationalize child marriage, the odds of physical and emotional IPV were lower for women who married over the age of 18 than women who were 14 and younger when they married. However, there was a confounding effect when considering age at marriage as 18 and over when community-level predictors were not included in the model estimating physical abuse. This underscores the need to consider the nested nature of respondents' experiences. Further, national legislation that protects against child marriage was not associated with risk of physical or emotional IPV. However, population size increased the odds of physical IPV and lowered the odds of emotional IPV. Such findings can be interpreted in light of opportunity theory and provide direction for prevention and intervention programming.

It Ain't Over Till It's Over?: Correlates of Post-Separation Abuse Among Unmarried Women in the Republic of Korea

This study investigates the correlates of post-separation abuse among unmarried women in the Republic of Korea (n = 744). The study employs a logistic regression model to consider if prior intimate partner violence victimization, relationship characteristics, and separation characteristics are associated with post-separation abuse. The results showed that experiencing coercive control by the former partner during the relationship, initiating the separation, and having a lower income than her former partner's income increased the odds of post-separation abuse. The findings imply that programs designed to prevent victimization or enhance victims' safety need to consider broader relationship and separation contexts.

Intimate Partner Violence and Age at Marriage in Mali: The Moderating Influence of Polygynous Unions

Polygyny and early marriage - both prevalent in Mali - are risk factors for intimate partner violence (IPV). Relying on data from the 2018 Malian Demographic and Health Surveys, the study examines the effects of polygyny and age at marriage, while controlling for known risk factors of IPV, on the likelihood of experiencing IPV. Findings reveal that polygyny is associated with IPV. However, polygyny has a moderating influence on the association between age at marriage and the experience of physical abuse and controlling behavior. The complex nature of women's experiences and the need for culturally specific programming are reviewed.

Examining the Relationship Between Victimization, Psychopathy, and the Acceptance of Rape Myths

Rape myths are attitudes that implicitly and explicitly blame victims for their own sexual victimization. Greater adherence to rape myths is linked to several negative outcomes, including the neutralization of gender-based violence and the perpetration of sexual violence. Few studies have considered how previous life experiences and individual-level traits influence the development and greater adherence to rape myths. The current study examines how traits associated with the three-factor model of psychopathy (i.e., egocentric, callous, and antisocial dimensions) and adherence to traditional gender roles mediate the relationship between prior childhood/adolescent victimization and the acceptance of rape myths in a sample of college men and women (N = 789). Path modeling indicates that experiences of psychological victimization (before age 16) increased egocentric psychopathic traits, which then increased the acceptance of rape myths in men. In women, however, sexual victimization (before age 16) increased the acceptance of traditional gender roles, which then influenced the acceptance of rape myths. Additionally, the egocentric facet of psychopathy exerted indirect effects on the acceptance of rape myths through traditional views on gender roles in both men and women. These findings highlight the need to continue to examine egocentric personality traits in relation to the development of rape myths in adolescent and young adult populations. Directions for collegiate programming are discussed.

Gender differences in the victim-offender overlap for dating violence: The role of early violent socialization

BACKGROUND

Intimate partner violence (IPV) is a serious problem in dating relationships among college students. The cycle of violence and social learning perspectives suggest that early violent socialization - inclusive of adverse socialization (i.e., prosocial violent messages, witnessing violence, or victimization by someone other than family) and experiences of child maltreatment - is one of the most robust risk factors for IPV involvement.

OBJECTIVE

The effects of early violent socialization were explored to understand the underlying mechanisms that influence victimization, perpetration, and the victim-offender overlap in IPV.

PARTICIPANTS AND SETTING

Using data from the International Dating Violence Study, we examined the role of early violent socialization on physical violence victimization and/or perpetration among U.S. college students in a dating relationship during early adulthood (N = 3447; aged 18 to 25 years).

METHODS

Multinomial regressions were estimated. Models were stratified across gender.

RESULTS

Findings indicated that 35% of participants reported IPV involvement, with 24.4% of the total sample reporting membership in the victim-offender group. Adverse socialization (RRR = 1.03, p < .05) and sexual abuse (RRR = 1.03, p < .01) were associated with increased risk for involvement in the victim-offender group. Also, there were pronounced gender differences across the IPV involvement categories. Significant interactions between adverse socialization and neglect, as well as adverse socialization with physical abuse, emerged in the male sample.

CONCLUSIONS

Early adverse experiences might be crucial to prevent violence, and accounting for gender differences is important when designing prevention and intervention programs.

Differences in Nonresponse Bias and Victimization Reports Across Self-Administered Web-Based and Paper-and-Pencil Versions of a Campus Climate Survey

Using a standardized campus climate survey that was disseminated across three modes of administration (N = 5,137), this study assesses the nonresponse bias of two web-based versions to a self-administered paper-and-pencil version conducted at a Southeastern 4-year university. Significant differences emerged across all three modes of administration and victimization measures (bullying, sexual assault, rape, emotional abuse, and intimate partner violence [IPV]). Respondents were more likely to report victimization in the web-based surveys administered to online-only classes and via mass email compared to the paper survey. Policy implications, especially as it relates to survey administration, are discussed.

Help-Seeking Behaviors of Intimate Partner Violence Victims: A Cross-National Analysis in Developing Nations

There is a dearth of research on help-seeking behaviors of intimate partner violence (IPV) victims, especially within developing nations. The current study uses the nationally representative population-based Demographic and Health Surveys (DHS) of 31 nations to address this gap in the literature. Specifically, the study (a) assesses the extent to which IPV victims sought help in developing nations, (b) investigates from whom IPV victims sought help, and (c) evaluates individual and national factors that influence the likelihood of help seeking among IPV victims in developing nations. Given the hierarchical structure of the data, multilevel modeling techniques are used (individual level N = 65,530; national level N = 31). Descriptive findings revealed 34.88% of IPV victims engaged in help-seeking behaviors and the majority of victims who sought help reached out to family members (63.10%). Few IPV victims (3.24%) sought help from formal institutions. Results from the hierarchical generalized linear regression models indicated the severity of abuse, attitudes toward IPV, and indicators of empowerment all affected the likelihood of help seeking. National-level factors, including whether the nation had a law against IPV, were not significant. While providing formal services is important, policies designed to help IPV victims must recognize and address cultural barriers that may inhibit help-seeking behaviors. Because the majority of IPV victims sought help from informal support networks, it is important that individuals in these extended networks receive information about gendered norms and IPV so they can extend help and respond appropriately to family and friends.

Parts Unknown: Risk Factors of Intimate Partner Violence in Azerbaijan, Kyrgyzstan, Tajikistan, and Moldova

Extant research has argued that there are variations in predictors of intimate partner violence (IPV) across nations and it is necessary to examine country-specific correlates of IPV. Much remains unknown about factors that affect risk of IPV in transitional countries. Specifically, we explore risk factors for IPV among four former nations of the Soviet Union-Azerbaijan, Kyrgyzstan, Tajikistan, and Moldova-with data from the nationally representative Demographic and Health Surveys. Rates of physical abuse were similar within Tajikistan (18.96%) and Moldova (18.38%), while Kyrgyzstan (20.62%) had the highest prevalence and Azerbaijan (9.29%) had the lowest prevalence. In contrast, the prevalence of sexual abuse was very similar across the four countries and was much lower (between 1.00% and 3.50%) than cross-national estimates of physical abuse. Findings suggest that many of the same risk factors of IPV in developing and developed nations influence risk of IPV in transitional nations. Across the four former Soviet nations included in analyses, the experience of controlling behaviors, husband's alcohol use, and witnessing IPV or experiencing abuse during childhood were all significantly associated with risk of physical and sexual abuse later in life. Indeed, the intergenerational transmission of violence may be a cross-national phenomenon. In addition, equality in decision making did not have an effect on risk of physical and sexual violence, except for risk of physical abuse in Moldova. This may be due to the historical context of these nations. Taken together, findings suggest that country context may influence individual risk factors of IPV.

The Association between Adherence to Sexist Beliefs and Traditional Family Norms, Religion, and Attitudes toward Sexual Minorities

Much remains unknown about the collective influence of adherence to sexist beliefs and traditional family norms on attitudes toward sexual minorities. Understanding factors that shape attitudes are important as attitudes can influence the development of laws and policies. This is particularly salient as rights gaps remain in spite of recent legal victories for sexual minorities in the U.S. Using a weighted nationally representative sample (N = 3,647) from the 2016 American National Election Studies, the current study examined the association between adherence to sexist beliefs and traditional family norms, religion, and attitudes toward sexual minorities. Individuals with a stronger adherence to sexist beliefs and traditional family norms have less favorable attitudes toward sexual minorities. This finding illustrates the nexus of sex, gender, and sexuality, and shows their collective association with attitudes toward sexual minorities. Findings can inform advocacy efforts and initiatives that address misconceptions regarding sexual minorities and what characteristics constitute masculinity and femininity.

"Most [False Reports] Involve Teens": Officer Attitudes Toward Teenage Sexual Assault Complainants-A Qualitative Analysis

Scholars, advocates, and victims have repeatedly criticized the police treatment of sexual assault (SA) complainants. Apathetic attitudes and hostile behavior on the part of the police have likely resulted from socialization into a culture that condones the use of force and violence and blames SA victims for their victimization. Using data from in-depth semistructured interviews with 52 Los Angeles Police Department sex crimes detectives, we examine officer attitudes toward teenage complainants of SA. Notably, almost three fourths of the respondents (n = 38; 73%) mentioned that teenagers lie about SA. Practical implications, theoretical advancements, and directions for future research are discussed.

Correlates of Cyberstalking Victimization and Perpetration Among College Students

Few studies have examined theoretical predictors of cyberstalking victimization and offending. The current study, guided by self-control theory and a feminist framework, analyzed predictors of cyberstalking victimization and offending among undergraduate college students (N = 662). College women were at increased risk of cyberstalking victimization, but were also more likely to report having engaged in cyberstalking perpetration. Higher levels of self-control reduced the likelihood of cyberstalking victimization and offending. While Greek life membership and holding adversarial heterosexual beliefs did not affect cyberstalking victimization and offending, gender stereotyping decreased the odds of experiencing cyberstalking victimization. Implications for future research and practice are discussed.

The effects of individual- and national-level factors on attitudes toward child maltreatment

Knowledge is lacking regarding the extent to which national norms and policies designed to protect minors influence individual attitudes toward child maltreatment. Relying on the tenets of cultural sociology, we examine whether the orientation of a nation influences individual attitudes toward child maltreatment. Specifically, nations with greater economic and political stability tolerate more self-expressive values, focusing on individual autonomy and enhancing quality of life. Conversely, nations with a survivalist orientation, often characterized by greater economic uncertainty, are less supportive of behaviors that may result in further instability. The current study builds on extant research by investigating the effects of national norms and policies and individual-level attitudes and characteristics on individual attitudes toward child maltreatment (N = 66,391) in 53 developing and developed nations. We analyze data from the World Values Survey using Hierarchical Generalized Linear Modeling. Overall, countries with a greater survivalist orientation appear less tolerant of child maltreatment. Moreover, greater support for violence in general at both the national- and individual-level are associated with more supportive attitudes toward child maltreatment. Policy implications and legislative reform are discussed.

Bystander Intervention to Abusive Behavior on Social Networking Websites

The current study assessed which bystander intervention behaviors individuals reported they would engage in when exposed to abuse in their online network and the correlates of these behaviors. Data were drawn from college students' responses ( N = 600) to three vignettes, ranging in severity, where the respondent's male friend commented about his ex-girlfriend on a social network. Although it was hypothesized respondents would intervene on the website when exposed to abuse, results suggested this was not the case. Respondents were more likely to offer support to the victim, report the behavior, and recommend programming for the most severe scenario. Implications are discussed.

The Intersection of Stalking and the Severity of Intimate Partner Abuse

Using data from the Chicago Women's Health Risk Study (N = 464), this study examined the intersection of stalking and the severity of intimate partner abuse while controlling for previously identified risk factors of intimate partner homicide. Findings indicate that (a) victims of life-threatening abuse by an intimate partner were significantly more likely to experience stalking than victims of nonlethal abuse; (b) after controlling for key risk factors, stalking increased the risk of life-threatening abuse; and (c) threats to kill the victim if she left was the only significant stalking-related behavior that increased the risk for life-threatening abuse. In addition, an offender's prior record and a higher number of previous abusive incidents increased the risk of life-threatening abuse. Implications for prevention and future directions for research are discussed.

Risk Factors of Physical and Sexual Abuse for Women in Mali: Findings From a Nationally Representative Sample

Mali is a developing country that has marked inequalities between genders. Using the 2012-2013 Mali Demographic and Health Survey, a nationally representative sample of Malian women ( N = 2,527), the study examined the effect of controlling behaviors, childhood exposure to and experience of violence, husband's alcohol use, woman's use of violence, and sociocultural factors on the likelihood of experiencing physical and sexual abuse. Findings indicated that controlling behavior, childhood exposure to violence, and husband's use of alcohol were predictors of physical and sexual abuse. Respondent's use of violence increased risk of physical abuse. Implications for programming in Mali are discussed.

Place matters: Contextualizing the roles of religion and race for understanding Americans' attitudes about homosexuality

As laws and policies related to homosexuality have evolved, Americans' attitudes have also changed. Race and religion have been established as important indicators of feelings about homosexuality. However, researchers have given almost no attention to how county characteristics shape Americans' attitudes. Using Hierarchical Linear Modeling techniques, we examine how personal characteristics and the religious and racial context of a county shape feelings about homosexuality drawing on data from the American National Election Survey and information about where respondents reside. We find that African Americans initially appear less tolerant than other racial groups, until we account for the geographical distribution of attitudes across the nation. Additionally, once we consider religious involvement, strength of belief, and religious affiliation African Americans appear to have warmer feelings about homosexuality than whites. Drawing on the moral communities' hypothesis, we also find that the strength of religiosity amongst county residents heightens the influence of personal religious beliefs on disapproving attitudes. There is also a direct effect of the proportion conservative Protestant, whereby people of all faiths have cooler attitudes towards homosexual individuals when they reside in a county with a higher proportion of conservative Protestants. Finally, we do not find any evidence for an African American cultural influence on attitudes.

Gender difference in vascular and platelet reactivity to thromboxane A(2)-mimetic U46619 and to endothelial dependent vasodilation in Zucker fatty (hypertensive, hyperinsulinemic) diabetic rats

We examined the hypothesis that gender differences exist in platelet and vascular reactivity in type-2 diabetes mellitus, using Zucker fatty diabetic rats of both sexes and their lean littermates. Type-2 diabetes is characterized by excessive platelet production of TXA(2), which is thrombogenic. Testosterone up-regulates platelet TXA(2) receptors and the aggregation response to thromboxane mimetics. Conversely, estrogen increases vascular nitric oxide (NO) production and inhibits platelet aggregation. Hemodynamic studies were undertaken with the determination of dose-response curve for MAP and renal cortical blood flow (RCF) in response to U46619, angiotensin-II, phenylephrine and endothelin-1, as well as the systemic hemodynamic response to acetylcholine and L-NG nitro-arginine methylester (L-NAME). Platelet aggregation response was evaluated using whole blood impedance aggregometry. There were significant gender differences in the systemic blood pressure and RCF response to TXA(2)-mimetic U46619 and angiotensin-II (P<0.02, ANOVA) but not to phenylephrine or endothelin-1. Male rats exhibited a paradoxical hypotensive response to U46619 (-18+/-11 mmHg) compared with a peak pressor response of +6+/-1 mmHg in female rats (P<0.01, ANOVA). The male rats exhibited an attenuated systemic vasodilator response (P<0.001, ANOVA) to acetylcholine (fall in MAP in male diabetic rats being -24+/-8 mmHg, compared with a fall of -50+/-8 mmHg in females), but a greater rise in the renal cortical resistance in response to NO inhibition by L-NAME (P<0.03) compared with the female rats. Both the slope (46+/-2) and the peak magnitude of the U46619-induced whole blood platelet aggregation (13+/-1) ohms were significantly higher (P<0.01, ANOVA) in male (n=10) compared with female diabetic rats (n=8) (29+/-0.8 slope, 10.0+/-0.8 ohms, respectively). Thus, the male diabetic Zucker rats exhibited an impaired response to vasoconstrictors (U46619 and angiotensin-II) and to endothelial (NO)-mediated vasodilation. The male gender may therefore be associated with the greater prothrombotic activity and a worse impairment of endothelial reactivity in the type-2 diabetic state.

Butyrate inhibits proliferation-induced proliferating cell nuclear antigen expression (PCNA) in rat vascular smooth muscle cells

Arterial injury-induced vascular smooth muscle cell (VSMC) proliferation in intima is the important etiologic factor in vascular proliferative disorders such as atherosclerosis, hypertension and restenosis after balloon angioplasty. Butyrate, a naturally occurring short chain fatty acid, is produced by bacterial fermentation of dietary fiber and by mammary glands of certain mammals. Studies have shown that butyrate at millimolar concentrations, which are physiological, induces growth arrest, differentiation and apoptosis. We examined the effect of physiological concentrations of butyrate on rat VSMC proliferation and proliferation-induced PCNA expression to determine anti-atherogenic potential of butyrate. Butyrate concentrations, closer to physiological range, exhibited antiproliferative effects on both serum-induced proliferation of serum-starved quiescent VSMCs and actively proliferating non-confluent VSMCs. Treatment of serum-starved quiescent VSMCs with 1-8 mmol/l concentration of butyrate caused a concentration-dependent decrease in serum-induced VSMC proliferation and cell proliferation-associated increase in total cellular proteins and RNA levels. Similarly, exposure of actively growing VSMCs to 5 mmol/l butyrate resulted in the inhibition of cell proliferation and proliferation-induced increase in cellular proteins and RNA levels. Furthermore, cellular morphology was significantly altered. Analysis of cell cycle regulatory proteins indicated that levels of PCNA, an excellent marker for cell proliferation, was significantly altered by butyrate both in actively proliferating and serum-induced quiescent VSMCs. These observations suggest that butyrate exhibits potential antiatherogenic capability by inhibiting VSMC proliferation and proliferation-associated increase in PCNA expression and thus merits further investigations regarding therapeutic significance of butyrate in vascular proliferative disorders.

Use of the theory of reasoned action to predict drug and alcohol use

The present study examines the role of self-esteem (SE) in the prediction of drug and alcohol use. Consistent with research on the theory of reasoned action, we suggest that alcohol and drug attitudes and subjective norms are more useful in the prediction of self-reported drug and alcohol consumption than SE. In the present study, measures of SE, drug attitudes, subjective norms, and drug use behaviors were collected from 2,074 high school and college students. Results indicate that drug attitudes and subjective norms do predict drug and alcohol use, but that SE does not add significantly to the prediction of the drug and alcohol behaviors.

Measuring intramedullary nails

Determining the length of nail needed for intramedullary nailing can sometimes be difficult. This article describes a simple procedure for taking this important measurement.

Satisfaction with health-related educational workshops: the role of environmental and logistical factors

The present study examined correlates of the perceived quality of four educational conferences. Specifically, the study examined the relationships of ratings of subjective overall conference quality with environmental and logistical aspects of the conferences. The results showed that ratings of room quality as well as ratings of meeting structure were significantly related to ratings of overall conference quality. Follow-up coverall conference ratings, measured up to one year after the conferences, were predicted by initial ratings of food quality.

How to weigh a patient who is over 350 pounds

Every so often a physician needs to weigh someone who exceeds the weight limit of the standard office scale. This short tip describes an easy and quick method of obtaining the weight of someone who is over 350 pounds.

Semicarbazide-sensitive amine oxidase activity in streptozotocin diabetic rats

Semicarbazide-sensitive amine oxidase (SSAO) activity was investigated in serum and tissues of streptozotocin diabetic rats. Diabetes was induced by a single intraperitoneal injection of streptozotocin (STZ, 60 mg/kg) and rats were killed at 1, 3, 7, 9, 14, 28 and 56 days after treatment. STZ increased serum glucose and serum SSAO activity at all time points with a maximal increase (2 to 3 fold) at day 7. Kidney SSAO activity showed significant increases on days 9 and 14 (2.5 and 4 fold, respectively). SSAO activity of aorta, lung and pancreas was not changed significantly. Kinetic analysis showed that the elevation in both serum and kidney SSAO activity was due to an increased Vmax with no change in Km. SSAO activity appears to be selectively increased in the serum and kidney of STZ diabetic rats which may be indicative of a relationship between serum SSAO and early renovascular damage in this animal model of diabetes mellitus.

Benzylamine oxidase activity in spontaneously hypertensive rats

Benzylamine oxidase (BzAO) activity was assayed in aorta, atria and serum from 20 week old spontaneously hypertensive (SH) rats and Wistar Kyoto (WKY) control rats. Atrial BzAO activity was reduced by 50% in SH rats compared with WKY control. Aorta and serum BzAO activity did not differ significantly between the two groups. Thus, BzAO activity of serum and cardiovascular tissues appears unrelated to pressure-induced changes in connective tissue production.

Limitations of thermodilution cardiac output measurements in the rat

Heat loss from the vascular system could introduce an error in thermodilution cardiac output determinations. Cardiac output measured in the rat via the thermodilution technique following right atrial injection yielded different values (P less than 0.001), depending whether sampling was from the pulmonary artery (460 +/- 31 ml X min-1 X kg-1), right ventricle (311 +/- 19), or thoracic aorta (245 +/- 15). Recirculation errors could not account for the differences. Heat loss from the vascular system was measured from extravascular thermistors within both the thorax and the abdomen. These dilutions were 22-57% in peak height of aortic curves recorded at approximately the same location. Differences in calculated cardiac output between sampling sites could be attributed to rapid heat conduction directly from the right atrium and inferior vena cava to the thoracic aorta with progressive loss of indicator from both the right ventricle and pulmonary artery.

Effect of ovariectomy and estrogen treatment on uterine benzylamine oxidase and monoamine oxidase type A

The activity of monoamine oxidase type A (MAO-A) of rat uteri is known to be modulated by sex steroids but no information is available with regard to benzylamine oxidase (BzAO). Thus, uterine MAO-A and BzAO activities were assayed in ovariectomized (3 weeks) and ovariectomized plus estrogen treated rats (17 beta-estradiol, 10 micrograms/kg/day, i.p. for three days). Compared with sham operated controls, MAO-A activity (total and specific) was decreased by ovariectomy and restored partially by estrogen treatment. In contrast, BzAO activity was not influenced selectively. Total BzAO activity followed changes in uterine weight such that the specific activity of BzAO, per mg tissue, was not statistically different between the three experimental groups. Although changes in the specific activity of BzAO were found on a protein and DNA basis, these changes reflect primarily alterations in protein and DNA contents and not BzAO activity. Since BzAO appears to be insensitive to direct modulation by sex steroids and may be located predominantly in uterine blood vessels, it is speculated that the enzyme may serve as a marker for hormonal influences on the vascularity and structure of the uterine vascular bed.

Benzylamine oxidase in normal and atherosclerotic human aortae

Assays of serum benzylamine oxidase (BzAO) have led some workers to postulate a relationship between elevated BzAO activity and diseases characterized by proliferating connective tissue. The present study was designed to determine whether BzAO activity of a cellular tissue is also affected. BzAO was assayed in homogenates of normal and atherosclerotic human aortae. Characterization done in normal aortae showed that BzAO is not a classical monoamine, diamine, polyamine, or lysyl oxidase, nor is it a ceruloplasmin. The enzyme is heat stable at 60 degrees C and is associated primarily with the microsomal fraction on density centrifugation. Compared with phenylethylamines and indoleamines, benzylamine is the best substrate. BzAO is sensitive to inhibition by hydrazines and chymotrypsin but not trypsin, and is insensitive to Triton X-100 and sulfhydryl-group blockade. BzAO activity of atherosclerotic plaque (expressed per gram wet weight or per milligram protein) was decreased markedly compared to that in adjacent, nonplaque regions and in normal aortae. However, on a per milligram DNA basis, the BzAO activity of plaque did not differ from that of nonplaque tissue. We conclude that there is a decreased cell population density in plaque, a contention supported by kinetic analysis. Plaque BzAO showed a decreased Vmax with no change in the Km of benzylamine compared with nonplaque tissue. Thus, if a relationship exists between BzAO activity and proliferating connective tissue, it is not apparent at the level of the cellular enzyme in atherosclerotic aortae of man.

Pulmonary artery catheterization in the rat

A method of pulmonary artery (PA) catheterization in the closed-chest rat is described. This catheterization is best accomplished with teflon catheters having a "shepherd's crook" tip. Catheter preparation is detailed. The functional advantages of such a PA catheter are: 1) the tip can remain free within the right ventricle (RV) without becoming occluded by contact with the ventricular wall, and 2) entry into the PA is simple and reproducible. Dual catheterization of the RVand PA produced only a small systolic gradient (3 mmHg) across the pulmonic valve. We concluded that the PA catheter does not unduly obstruct blood flow through this valve.
