Gender symmetry in prevalence, severity, and chronicity of physical aggression against dating partners by university students in Mexico and USA

The paper reports results from analyses of the physical aggression against dating partners by four samples of university students in Ciudad Juarez, Mexico, Mexican Americans and Non-Mexican Whites in El Paso and Lubbock Texas, and New Hampshire (N=1,544). The percent reporting partner violence (PV) was high in all samples, but also differed significantly between samples. The lowest rate was in New Hampshire (29.7%), followed by Texas, Non-Mexican Whites (30.9%), Texas Mexican American (34.2%), and the highest rate was in Juarez (46.1%). When only severe assaults were compared, the differences between samples was similar, i.e., lowest in New Hampshire and highest in Juarez. In all four samples, there was no significant difference between males and females in either the overall prevalence of physical aggression or the prevalence of severe attacks. Among the 553 couples where one or both of the partners were violent, in almost three quarters of the cases (71.2%) there was gender symmetry in the sense that both partners engaged in this type of behavior. When only one partner was violent, this was twice as likely to be the female partner (19.0%) as the male partner (9.8%). Among the 205 couples where there was an act of severe aggression, symmetry was less prevalent (56.6%), but when only one partner was violent, it was again twice as likely to be the female partner (29.8% female only versus 13.7 male partner only). These results are consistent with the gender symmetry in PV found in many studies. They extend those results by showing that gender symmetry prevails in four different cultural contexts. The presence of gender symmetry in these different cultural contexts, combined with studies showing that women are injured more often and more seriously by partner-assaults, and studies showing that women initiate PV as often as men, suggests that programs and policies aimed at primary prevention of PV by women are crucial to ending PV and for reducing the victimization of men and women.     

Automatic activation of Yellow Peril Asian American stereotypes: effects on social impression formation

The authors randomly assigned 69 undergraduates to 1 of 2 perceptual priming conditions involving 80-ms flash words presented on a computer screen to activate information processing outside of conscious awareness. In the high-prime condition, the authors exposed participants to stereotype words associated with the Yellow Peril view of Asian Americans. The authors exposed participants in a low-prime condition to neutral words. All participants then read a vignette and evaluated its protagonist on several social dimensions. Results indicated that the priming procedure effectively biased participant evaluation of the vignette target, but only on items closely linked to Asian Americans. Contrary to predictions, however, participants in the high-prime group rated the target less Asian than did their low-prime group counterparts, an apparent reversal of the expected priming effect. The authors discussed theoretical implications.     

Modulation of working, short- and long-term memory by nicotinic receptors in the basolateral amygdala in rats

Male Wistar rats were exposed to one-trial step-down inhibitory avoidance training using a 0.5 mA footshock. Through bilaterally implanted indwelling cannulae, they received bilateral 0.5 microL infusions of saline, mecamylamine (1.0 or 10.0 microg/side), or nicotine (0.6 or 3.0 microg/side) into the basolateral complex of the amygdaloid nucleus (BLA). Infusions were either 10 min before training (Experiment 1) or 4 min after training (Experiment 2). In Experiment 1, the animals were tested three times: first for working memory (WM) 5 s after training, then for short-term memory (STM) 90 min later, and finally for long-term memory (LTM) 24 h later. Mecamylamine depressed and nicotine enhanced WM, STM, and LTM. In Experiment 2, the treatments were given after WM was presumably over. Again, mecamylamine inhibited and nicotine enhanced STM and LTM. The results indicate that nAChRs in BLA participate in the regulation of WM formation and STM and LTM acquisition and consolidation.     

suspicion of sudden infant death syndrome & injuries to infants: the effects of type of death certifier,training, and economics

This paper examines the level of suspicion by death certifiers when ruling infant deaths as accidents. Data were gathered on economic factors, amount of training in death investigation received, and personal characteristics for 1995 from 776 medical examiners or coroners. Findings indicate that personal and social factors such as age, education, and population have negligible or no effects on the level of suspicion held by death certifiers in manner of death rulings for infants. The findings from this study do suggest there is potential for inaccurate rulings of infant death due to lack of training, education, and economic resources depending on the events surrounding an infant's death and whether the death certifier is a coroner or medical examiner.     

Relational and item-specific influences on generate–recognize processes in recall

The generate–recognize model and the relational–item-specific distinction are two approaches to explaining recall. In this study, we consider the two approaches in concert. Following Jacoby and Hollingshead (Journal of Memory and Language 29:433–454, 1990), we implemented a production task and a recognition task following production (1) to evaluate whether generation and recognition components were evident in cued recall and (2) to gauge the effects of relational and item-specific processing on these components. An encoding task designed to augment item-specific processing (anagram-transposition) produced a benefit on the recognition component (Experiments 1–3) but no significant benefit on the generation component (Experiments 1–3), in the context of a significant benefit to cued recall. By contrast, an encoding task designed to augment relational processing (category-sorting) did produce a benefit on the generation component (Experiment 3). These results converge on the idea that in recall, item-specific processing impacts a recognition component, whereas relational processing impacts a generation component.     

Natural Disaster and Risk of Psychiatric Disorders in Puerto Rican Children

We examined the persistence of psychiatric disorders at approximately 18 and 30 months after a hurricane among a random sample of the child and adolescent population (4–17 years) of Puerto Rico. Data were obtained from caretaker-child dyads (N = 1,886) through in person interviews with primary caretakers (all children) and youth (11–17 years) using the Diagnostic Interview Schedule for Children IV in Spanish. Logistic regressions, controlling for sociodemographic variables, were used to study the relation between disaster exposure and internalizing, externalizing, or any disorder. Children’s disaster-related distress manifested as internalizing disorders, rather than as externalizing disorders at 18 months post-disaster. At 30 months, there was no longer a significant difference in rates of disorder between hurricane-exposed and non-exposed youth. Results were similar across age ranges. Rates of specific internalizing disorders between exposed and unexposed children are provided. Research and clinical implications are discussed.     

Asymmetry in human cognition: further replication and extension

Vladimir Lefebvre proposed an algebraic model of self-reflexion in the 1980s. He viewed reflexion as a product of the structure and computational rules of Gamma algebra and his equations are considered metaphors for how consciousness is structured. From the framework of this model, Lefebvre hypothesized an asymmetry in human cognition. One of the early studies supporting his model was conducted by Victorina Lefebvre. Over the years, other studies have been conducted, but not all have shown similar support as the original findings of Victorina Lefebvre. This study attempted to extend her findings in testing whether or not other ambiguous stimuli could be used in support of the model.     

DOMESTIC VIOLENCE AND WOMEN'S MENTAL HEALTH IN CHILE

Domestic violence against women is a pervasive, global health problem. This study investigates the correlates and psychological outcomes of domestic abuse among women in a semi-industrial country. The participants included 215 mothers residing in working-class communities located on the outskirts of Santiago, Chile. We utilized structural equation modeling to test the hypothesis that poverty and other structural inequalities would be related to incidents of domestic abuse in Chile, as they are in the United States. Our results suggest that lower socioeconomic status, even within poor communities, and stressful life events have a direct relationship to domestic conflict. Domestic abuse was, in turn, associated with women's mental health such that greater domestic conflict was related to higher reports of depressive affect and symptoms of posttraumatic stress disorder. The importance of identifying similarities and differences in the occurrence of domestic violence in developing countries as compared to industrialized countries is discussed.     

Self-Efficacy and Sexual Purity among SDA Emerging Adults: A Bivariate Analysis*

Abstract

The purpose of this study was to examine the ability of SDA emerging adults (N?=?558) to remain sexually abstinent prior to marriage in spite of pressures to engage in such act. The researchers explored whether gender and racial differences exist among this group. The results showed a significant difference between SDA emerging males and females regarding their levels of self-efficacy (t _(df=372)?=?2.207; p?<?.05), and a significant difference among SDA emerging Caucasians, African Americans and other races as it relates to their levels of self-efficacy (F _{(df 2, 555)}?=?6.602, p?<?.05). The researchers recommend that religious institutions focus on the factors that influence the levels of self-efficacy, rather than simply emphasizing a sexually-abstinent lifestyle.
