Resolving Nationalist Conflicts: Promoting Overlapping Identities and Pooling Sovereignty—The 1998 Northern Irish Peace Agreement

Nationalist and ethnic conflicts are a continuing source of tension in the post–Cold War period. The underlying factors affecting such conflicts are threat perception, ethnic security dilemmas, and lack of trust between nationalist/ethnic groups. The challenge is to find solutions to these conflicts. International institutions can establish trust and reduce the ethnic security dilemma by providing multiple forums of representation, promoting overlapping identities, and pooling sovereignty. Pooling sovereignty across a number of international representative bodies leads to increased access to governmental policymaking, with each party having a stake in government, and leads to a reduction in political tension and conflict. Thus, international parliamentary institutions may provide a solution to these conflicts. The British-Irish Peace Agreement (Good Friday Agreement) of 1998 is examined as an illustration of this argument.     

NO QUICK FIXES: ADDING CONTENT ABOUT WOMEN TO ECOLOGY COURSE MATERIALS

This study reports on a three-semester model project designed to assess the impact of enriched content related to Women's and Gender Studies on students enrolled in an undergraduate ecology course. The two constructs of interest were (a) students' attitudes toward women in science and society and (b) students' assessment of the classroom climate for women. The data included 398 matched pretest and posttest survey responses from a control group, a minimal enrichment group, and an increased enrichment group. Findings indicated that, although small course revisions did not influence students' attitudes toward women in science and society, such revisions had a positive influence on students' assessments of the classroom climate.     

PERCEPTIONS OF RELATIONAL AND PHYSICAL AGGRESSION AMONG COLLEGE STUDENTS: EFFECTS OF GENDER OF PERPETRATOR, TARGET, AND PERCEIVER

This study examined gendered perceptions of relational and physical aggressive behaviors and personal experiences with both types of aggression. Prior research suggested that physical aggression by males and relational aggression by females would be perceived most negatively. College students (186 female, 128 male) rated the acceptability and harmfulness of aggression in scenarios in which type of aggression and perpetrator and target gender were varied. As predicted, relational aggression by female characters and physical aggression by male characters were rated as less acceptable and more aggressive/harmful than the same behavior by the other gender. Thus, expectations regarding the gender-appropriateness of aggression appear to affect perceptions of such acts. Despite popular conceptions that females use and are harmed by relational aggression more than males, there was no gender difference in experience with relational aggression, nor were female targets viewed as more harmed by such aggression than their male counterparts.     

Cognitive triad: Relationship to depressive symptoms,parents' cognitive triad,and perceived parental messages

Evaluating the relationship between children's depressogenic thinking, children's depressive symptoms, parents' depressogenic thinking, and perceived parental messages about the self, world, and future was the primary objective of this investigation. Children (n =133) from grades 4 to 7 completed measures of depression and anxiety, including a semistructured clinical interview, a measure of their cognitive triad, and a measure of perceived parental messages about the self, world, and future. Mothers (n =112) and fathers (n =95) completed a measure of their own cognitive triad. Results of a series of regression analyses revealed that (1) children's views of self, world, and future (cognitive triad) are related to severity of depression; (2) mothers' but not fathers' cognitive triads are related to their children's cognitive triads; (3) perceived parental messages to the children about the self, world, and future are predictive of the children's cognitive triads and ratings of depression; and (4) the relationship between perceived parental messages and depression is completely mediated by children's cognitive triads. Analyses of covariance indicated that the obtained mediational relationship between children's views of self, world, and future, perceived parental messages, and children's depressive symptoms was specific to depressive versus anxious symptomatology. Impfications for existing theory and research are discussed.     

Caffeine,impulsivity, and memory scanning: A comparison of two explanations for the Yerkes-Dodson Effect

Two explanations for the Yerkes-Dodson Effect (1908) were tested. Easterbrook (1959) proposed that arousal reduces the range of cue utilization. Thus, arousal should interfere with the capacity for simultaneous (dual) memory scans. In contrast, Humphreys and Revelle (1984) proposed that arousal facilitates sustained information transfer but interferes with short-term memory. Arousal should thus reduce the time needed to prepare to respond but increase the time needed to scan memory. Either caffeine or placebo was given to 78 subjects who differed in impulsivity. They completed three versions of a memory-scanning task: two single-task versions (physical and category matches) and one dual-task version (either type of match). As predicted by Humphreys and Revelle, relative to placebo, caffeine lowered the intercept (p<.01), suggesting facilitation of sustained information transfer, but increased the slope (p<.05), suggesting impairment of access to short-term memory, of the regression of reaction time on log-transformed memory-set size. That caffeine had a main effect on slopes and on intercepts but did not interact with type of task suggests that arousal does not necessarily disrupt dual-task performance.     

Reinforcement uncertainty enhances preference for choice in humans

Under concurrent‐chains schedules of reinforcement, participants often prefer situations that allow selection among alternatives (free choice) to situations that do not (forced choice). The present experiment examined the effects of reinforcement probability on choice preferences. Preferences for free versus forced choice were measured under a condition in which participants' choices were always reinforced (reinforcement probability of 1.0) and a condition in which outcomes were uncertain (reinforcement probability of 0.5). Forty‐four college students participated and preferences were examined under a concurrent‐chains schedule of reinforcement. Participants preferred free choice under uncertain reinforcement, but a bias toward free choice was not observed when reinforcement was certain. These results align with previous findings of preference for free choice under conditions of uncertainty, but suggest that preference may be dependent upon probabilistic reinforcement contingencies in the terminal links of the concurrent‐chains arrangement. Thus, reinforcement probability is an important variable to consider when conducting similar studies on the value of choice.     

Developmental considerations for assessment of trauma symptoms in preschoolers: a review of measures and diagnoses

Child maltreatment can lead to a unique set of trauma stress among young children that can be challenging to measure. The purpose of this review was to review measures of maltreatment-related trauma outcomes (trauma-related symptoms and post-traumatic stress disorders) in very young children (ages 0–6) and to examine research trends in how and if child development is accounted for in this area of measurement. A systematic search strategy was used to identify articles in two databases, CINAHL and PsychInfo. Articles were eligible for inclusion in the review if they measured trauma symptoms in children ages 0–6, were quantitative research reports of studies conducted in North America, and were published in English. The search resulted in 74 articles meeting prespecified inclusion criteria. Results suggested that recognition of the ways maltreatment trauma affects child development and the importance of developmental sensitivity in assessing trauma symptoms has grown in recent years. However, many research studies did not use developmental frameworks and applied adult-oriented trauma symptom frameworks in measurement and treatment. Behavioral symptoms were the primary outcome of interest for this age group. There was also incongruity and lack of consensus about diagnostic tools for post-traumatic stress disorders in young children. Further research is needed to resolve theoretical and empirical controversies related to measurement and diagnosis of trauma symptomatology in young children.     

The Sociocultural Context of Sexually Diverse Women’s Sexual Desire

Women’s sexual desire is a complex, multifaceted phenomenon. According to the biopsychosocial model of female sexual function, a comprehensive understanding of women’s sexuality requires awareness of the presence of and interaction between biological, psychological, interpersonal, and sociocultural factors. Other sexuality scholars in the field have similarly stressed this perspective, emphasizing that sexual desire in particular is impacted by medical, relational, psychological, and sociocultural influences. Given the influence of sociocultural variables like sexism and heterosexism on women’s lives, we sought to understand the impact of the sociocultural context on sexual desire in 31 bisexual, lesbian, and heterosexual women. Women ranged in age from 20 to 69 and answered a number of questions related to their experience of sexual desire and the ways in which desire related to their sexual identity. The semi-structured interviews focused on women’s retrospective, subjective accounts of their experiences. Using a consensual qualitative research approach and thematic analysis, the interviews revealed four themes and seven subthemes: (1) minority stress (heterosexist discrimination, stigmatized identities, coming out, impact of visible/safe spaces); (2) gender expectations (gendered relationship expectations, gender binary impacts, body image); (3) religion; and (4) taboo and changing cultural times. Participant responses suggest that the sociocultural context can influence the sexual desire of diverse women, supporting both sexual desire exploration and suppression of desire expression by context. Practice and advocacy considerations include understanding of the impact of systems of privilege and oppression (e.g., sexism, heterosexism, racism) on women’s sexual desire experiences and opportunities for supporting diverse women’s sexual empowerment.
