Assault injury presentation and lifetime psychological trauma in emergency centre patients in South Africa
Patients presenting with assault injuries are at risk for injury recurrence, have high levels of past psychological trauma, and should be screened for psychosocial risk. Further research is needed to assess the role of past psychological trauma in risk for assault injury, and clarify treatment needs. The role of EC-based interventions in injury prevention and mental health requires increased recognition in South African policy and practice. (Psyc…
Food insecurity and intimate partner violence against women
Objective To investigate the association between food insecurity and intimate partner violence in a population-based sample of heterosexual women. Design Logistic regression was used to evaluate the association between three levels of food insecurity and intimate partner violence. Setting Data from 6 years of the California Women’s Health Survey. Subjects Randomly selected women ( n 16 562) aged 18 years and older from the State of California, US…
Sexual Risk Behaviors and Substance Use Among Men Sexually Victimized by Women
Objectives. To investigate whether forced sex of men by women was associated with sexual risk behaviors, and whether this association was mediated by substance use. Methods. Data from US men aged 18 years or older at interview in the National Survey of Family Growth 2006–2010 (n = 8108) who reported sexual behavior history. Outcome variables were condom use at most recent sex and number of lifetime sexual partners. Sexual activity covariates incl…
Cumulative burden of lifetime adversities
This study examined the utility of a lifetime cumulative adversities and trauma model in predicting the severity of mental health symptoms of depression, anxiety, and posttraumatic stress disorder. We also tested whether ethnicity and gender moderate the effects of this stress exposure construct on mental health using multigroup structural equation modeling. A sample of 500 low-socioeconomic status African American and Latino men and women with h…
Validation of the Self Reporting Questionnaire 20-Item (SRQ-20) for Use in a Low- and Middle-Income Country Emergency Centre Setting
Civil Examinations and Meritocracy in Late Imperial China
Few late imperial Chinese institutions were as important as the civil service examinations, and few scholars have contributed as much to their study as Benjamin Elman. Drawing on decades of researc
Relation of Childhood Sexual Abuse, Intimate Partner Violence, and Depression to Risk Factors for HIV Among Black Men Who Have Sex With Men in 6 US Cities
Objectives. We assessed the relation of childhood sexual abuse (CSA), intimate partner violence (IPV), and depression to HIV sexual risk behaviors among Black men who have sex with men (MSM). Methods. Participants were 1522 Black MSM recruited from 6 US cities between July 2009 and December 2011. Univariate and multivariable logistic regression models were used. Results. Participants reported sex before age 12 years with someone at least 5 years …
Impact of childhood sexual abuse on the emotions and behaviours of adult men from three ethnic groups in the USA
Adult men of different ethnic backgrounds who experienced childhood sexual abuse (CSA) may vary in their reports of the psychological and behavioural impact of CSA on their lives. Empirical studies rarely examine the impact of race/ethnicity or cultural context on the psychological and behavioural struggles of adult male CSA survivors. This study utilised qualitative content analysis to examine the reported CSA-related psychological and behaviour…
A Confirmatory Model for Substance Use Among Japanese American and Part-Japanese American Adolescents
Few studies have examined the effect of ethnicity and cultural identity on substance use among Asian and Pacific Islander adolescents. A cross-sequential study conducted in Hawai'i with 144 Japanese and part-Japanese American adolescents assessed a model integrating Japanese ethnicity, cultural identity, substance use, major life events, and social support. Japanese American adolescents scored higher on the Japanese Culture Scale and on the Peers…
Depression among Black bisexual men with early and later life adversities
This study examined the role of adulthood adversities in the relationship between childhood adversities and depression in 117 HIV-positive Black men who have sex with men and women (MSMW) and who have histories of childhood sexual abuse (CSA). Men were participants in the Enhanced Sexual Health Intervention for Men, a 6-session health intervention, and, at baseline, reported their experiences of CSA, childhood adversities, perceived discriminatio…
Gender Role Conflict Among African American Men Who Have Sex With Men and Women
Objectives. We investigated whether high gender role conflict (GRC; internal conflict with traditional gender-role stereotypes and an individual’s perceived need to comply with these roles) is associated with psychological distress and HIV-related risk behaviors in a sample of African American men who have sex with men and women (MSMW). Methods. We analyzed baseline data collected from questionnaires completed by 400 MSMW participating in the Men…
A Sexual Risk and Stress Reduction Intervention Designed for HIV-Positive Bisexual African American Men With Childhood Sexual Abuse Histories
Objectives. HIV transmission risk is high among men who have sex with men and women (MSMW), and it is further heightened by a history of childhood sexual abuse (CSA) and current traumatic stress or depression. Yet, traumatic stress is rarely addressed in HIV interventions. We tested a stress-focused sexual risk reduction intervention for African American MSMW with CSA histories. Methods. This randomized controlled trial compared a stress-focused …
Upper Paleolithic Levels XIII-VI (A and B) from the 1937-1938 and 1947-1948 Boston College Excavations and the Levantine Aurignacian at Ksar Akil, Lebanon
The rockshelter of Ksar Akil in Lebanon witnessed the most prolonged occupation of any single location during the Levantine Upper Paleolithic. Investigations began at the site in the early 1920s and have spanned almost 90 years. This paper examines the upper portion of the stratigraphic sequence, including the Levantine Aurignacian, and for the first time, correlates data collected in both the 1937-1938 and 1947-1948 field seasons of Boston Colle…
Learning From Successful Interventions
Few HIV prevention interventions have been developed for African American men who have sex with men or who have sex with both men and women. Many interventions neglect the historical, structural or institutional, and sociocultural factors that hinder or support risk reduction in this high-risk group. We examined ways to incorporate these factors into Men of African American Legacy Empowering Self, a culturally congruent HIV intervention targeting…
On the Outside Looking In
People of color are disproportionately affected by HIV/AIDS, yet African American HIV/AIDS researchers are in short supply. Complex historical, structural, sociocultural, and personal barriers can prevent African Americans from becoming well-trained biomedical, behavioral, and social HIV/AIDS researchers. Institutional factors that influence the numbers of African Americans conducting HIV/AIDS research include the limitation of early-career decis…
Risk Reduction for HIV-Positive African American and Latino Men with Histories of Childhood Sexual Abuse

A Confirmatory Model for Depression Among Japanese American and Part-Japanese American Adolescents
A confirmatory model integrating Japanese ethnicity, cultural identity, and depression was developed (N = 140). The model incorporated the Center for Epidemiologic Studies-Depression Scale (CES-D), Major Life Events Scale, and Japanese Cultural Scale. Japanese American adolescents scored higher on the Japanese Cultural Scale and reported fewer depressive symptoms on the CES-D total and on 2 of the 3 CES-D factors than part-Japanese American adole…
Psychosocial issues among gay- and non-gay-identifying HIV-seropositive African American and Latino MSM
This qualitative study examined sociocultural and behavioral factors including sexual health, sexual identity, and sexual risk among HIV-seropositive African American and Latino men who have sex with men (MSM) who also have a history of sexual abuse. Twenty-three men participated in 4 focus groups, responding to conceptually organized questions regarding the relationship between histories of violence and sexual and drug-related HIV risk behaviors…

Does a History of Trauma Contribute to HIV Risk for Women of Color? Implications for Prevention and Policy
Objectives. We investigated history of abuse and other HIV-related risk factors in a community sample of 490 HIV-positive and HIV-negative African American, European American, and Latina women. Methods. Baseline interviews were analyzed, and logistic regressions were used to identify predictors of risk for positive HIV serostatus overall and by racial/ethnic group. Results. Race/ethnicity was not an independent predictor of HIV-related risk, and …
Psychosocial issues among gay- and non-gay-identifying HIV-seropositive African American and Latino MSM
This qualitative study examined sociocultural and behavioral factors including sexual health, sexual identity, and sexual risk among HIV-seropositive African American and Latino men who have sex with men (MSM) who also have a history of sexual abuse. Twenty-three men participated in 4 focus groups, responding to conceptually organized questions regarding the relationship between histories of violence and sexual and drug-related HIV risk behaviors…
Tool Standardization in the Middle and Upper Palaeolithic
It has been postulated that one difference between Neanderthals and anatomically modern people lies in a ‘clearer mental template’ of flaked stone tools on the part of modern people. This is thought to have been manifested in greater tool standardization during the Upper Palaeolithic than in the Middle Palaeolithic. Testing of this hypothesis, using three samples of a characteristic Upper Palaeolithic tool class — burins — from one Middle Palaeol…
Sexual Behavior, Sexual Identity, and Substance Abuse Among Low-Income Bisexual and Non-Gay-Identifying African American Men Who Have Sex with Men
Child Sexual Abuse
As we move into the 21st century, information about sex is widespread and more accessible to the general public than ever before. This interest in sex also increases the focus on symptoms and patterns associated with sexual problems. However, the etiology of sexual dysfunction is multifaceted and poorly understood. One factor that has received growing attention is the role that early sexual abuse plays in sexual development and later sexual funct…

Spatial Cognition and Gender
Recent research has demonstrated that “sex differences” on mental image rotation (MIR) tasks may be attenuated through manipulations of instructional or stimulus conditions. The interaction of these variables was examined in two experiments. In the first, subjects received instructions that emphasized or de-emphasized the spatial nature of the MIR task. In the second, instructions emphasized the use of MIR abilities in stereotypically “masculine”…
