Negative genetic correlation for adult fitness between sexes reveals ontogenetic conflict in Drosophila

Because of their distinctive roles in reproduction, females and males are selected toward different optimal phenotypes. Ontogenetic conflict between the sexes arises when homologous traits are selected in different directions. The evolution of sexual dimorphism by sex-limited gene expression alleviates this problem. However, because the majority of genes are not sex-limited, the potential for substantial conflict may remain. Here we assess the degree of ontogenetic conflict in the fruit-fly, Drosophila melanogaster, by cloning 40 haploid genomes and measuring their Darwinian fitness in both sexes. The intersexual genetic correlations for juvenile viability, adult reproductive success, and total fitness were used to gauge potential conflict during development. First, as juveniles, where the fitness objectives of the two sexes appear to be similar, survival was strongly positively correlated across sexes. Second, after adult maturation, where gender roles diverge, a significant negative correlation for reproductive success was found. Finally, because of counterbalancing correlations in the juvenile and adult components, no intersexual correlation for total fitness was found. Highly significant genotype-by-gender interaction variance was measured for both adult and total fitness. These results demonstrate strong intersexual discord during development because of the expression of sexually antagonistic variation.

Traumatic insemination and sexual conflict in the bed bug Cimex lectularius

The bed bug, Cimex lectularius, has a unique mode of copulation termed “traumatic” insemination [Carayon, J. (1966) in Monograph of the Cimicidae, ed. Usinger, R. (Entomol. Soc. Am., Philadelphia), pp. 81–167] during which the male pierces the female's abdominal wall with his external genitalia and inseminates into her body cavity [Carayon, J. (1966) in Monograph of the Cimicidae, ed. Usinger, R. (Entomol. Soc. Am., Philadelphia), pp. 81–167]. Under controlled natural conditions, traumatic insemination was frequent and temporally restricted. We show for the first time, to our knowledge, that traumatic insemination results in (i) last-male sperm precedence, (ii) suboptimal remating frequencies for the maintenance of female fertility, and (iii) reduced longevity and reproductive success in females. Experimental females did not receive indirect benefits from multiple mating. We conclude that traumatic insemination is probably a coercive male copulatory strategy that results in a sexual conflict of interests.

Women Leaders Resolving Conflict in Higher Education: A Feminist Epistemological Perspective

In an American postsecondary context, conflict is inherent (Gianneschi & Yanagiura, 2006; Valian, 1999). Successful navigation of conflict in the academy is vital for those who aspire to leadership positions (Nadler & Nadler, 1987; Walters, Stuhlmacher, & Meyer, 1998). Presently, however, women face significant barriers to achieving success in higher education administration, including gender expectations for conflict resolution behavior (Bartunek, 1992; Bowles, Babcock, & McGinn, 2005; Gayle, Preiss, & Allen, 2002). While a considerable body of literature exists for understanding gender negotiation, it remains rooted in a masculine paradigm (Kolb & Putnam, 2006; Shuter & Turner, 1997), and, as such, established theories lack a feminist epistemological perspective. Consequently, my primary research question is, How do women leaders experience and perceive conflict in the higher education work environment? I conduct a qualitative study that examines workplace conflict experiences of 15 women leaders from diverse personal and professional backgrounds. Hartsock's (1983) three-tiered gender-sensitive analysis of power, updated to include multicultural perspectives, serves as my theoretical framework. It is a lens through which I evaluate theories, finding multicultural organizational, higher education conflict, and gender negotiation theories most applicable to this study. The framework also creates the foundation upon which I build my study. Specifically, I determine that a feminist research method is most relevant to this investigation. To analyze data obtained through in depth interviews, I employ a highly structured form of grounded theory called dimensional analysis. Based on my findings, I co-construct with study participants a Feminist Conflict Process Theory and Flowchart in which initially the nature of the relationship, and subsequently the level of risk to the relationship, institution, or self, is evaluated. This study supports that which is observed in the conflict resolution practitioner literature, but is unique in its observation of factors that influence decisions within a dynamic conflict resolution process. My findings are significant to women who aspire to serve in leadership positions in higher education, as well as to the academy as a whole, for it expands our knowledge of women's ontological and epistemological perspectives on resolving conflict in postsecondary education.

Successful Navigation of the Conflict between Doctoral Education and Cultural Expectations of Child Rearing in Hispanic Culture

While the numbers are slowly rising, Hispanic students continue to be disproportionately underrepresented in all levels of higher education, including doctoral education. There are many factors that may contribute to the low numbers of Hispanic doctoral students; for Hispanic women, one of these factors may be the perceived conflict between cultural expectations of childrearing and doctoral education. For Hispanic students who hold strong cultural values, this conflict may prevent enrollment in, or result in attrition from, doctoral education. As the number of Hispanic college enrollment increases, we will see more students trying to navigate between the collectivistic value of childrearing and the individualistic value of pursuing higher education. Thus, it is important to understand the needs of these students to aid in recruitment and retention of student-parents in all levels of higher education. This paper explores the barriers and supportive factors for current Hispanic doctoral student-parents. Suggestions are made to increase support which will allow these individuals to successfully complete a doctoral education, while attending to the responsibilities of parenting.

Post-Conflict Maternal Communication, Children's Understandings, and Child Functioning in Violent and Non-Violent Families

The last two decades have been marked by a growing public awareness of family violence. Research by social scientists has suggested that family violence is widespread (Gelles and Straus, 1988). It is estimated that every year 1.8 to 4 million women are physically abused by their partners (Novello, 1992). In fact, more women are abused by their husbands or boyfriends than are injured in car accidents, muggings, or rapes (Jaffe, Wolfe, and Wilson, 1990). A recent prevalence study by Fantuzzo, Boruch, Beriama, Atkins, and Marcus (1997) found that children were disproportionately present in households where there was a substantial incident of adult female assault. Experts estimate that 3.3 to 10 million children are exposed to marital violence each year (Carlson, 1984; Straus, 1991). Until recently, most researchers did not consider the impact of parental conflict on the children who witness this violence. The early literature in this field primarily focused on the incidence of violence against women and the inadequate response of community agencies (Jaffe et al, 1990). The needs of children were rarely considered. However, researchers have become increasingly aware that children exposed to marital violence are victims of a range of psychological maltreatment (e.g., terrorizing, isolation;Hart, Brassared & Karlson, 1996) and are at serious risk for the development of psychological problems (Fantuzzo, DePaola, Lambert, Martino, Anderson, and Sutton, 1991). Jouriles, Murphy and O'Leary (1989) found that children of battered women were four times more likely to exhibit psychopathology as were children living in non-violent homes. Further, researchers have found associations between childhood exposure to parental violence and the expression of violence in adulthood (Carlson, 1990). Existing research suggests that children who have witnessed marital violence manifest numerous emotional, social, and behavioral problems (Sternberg et al., 1993; Fantuzzo et al., 1991; Jaffe et al, 1990). Studies have found that children of battered women exhibit more internalizing and externalizing behavior problems than non-witnesschildren (Hughes and Fantuzzo, 1994; McCloskey, Figueredo, and Koss, 1995). In addition, children exposed to marital violence have been found to exhibit difficulties with social problem-solving, and have lower levels of social competence than nonwitnesses (Rosenberg, 1987; Moore, Pepler, Weinberg, Hammond, Waddell, & Weiser, 1990). Other reported difficulties include low self esteem (Hughes, 1988), poor school performance (Moore et al., 1990) and problems with aggression (Holden & Ritchie, 1991; Jaffe, Wolfe, Wilson, & Zak, 1986). Further, within the last decade, researchers have found that some children are traumatized by the witnessing experience, showing elevated levels of posttraumatic stress symptoms (Devoe & Graham-Bermann, 1997; Rossman, Bingham, & Emde, 1996; Kilpatrick, Litt, & Williams, 1997). These findings corroborate clinical reports that describe many exposed children as experiencing trauma reactions. It appears that the negative effects of witnessing marital violence are numerous and varied, ranging from mild emotional and behavioral problems to clinically significant levels of posttraumatic stress symptoms. These incidence figures and research findings indicate that children's exposure to violence is a significant problem in our nation today and has serious implications for the future.

Cultural conflict: Conveyance of traditional Iranian values and the effects on sense of self of Iranian-American women

The literature on Iranians who immigrated to countries with modern cultures is sparse. This paper presents a theoretical understanding of the research with a particular appreciation on issues related to gender roles, sexuality, and acculturation within this population. In addition, treatment suggestions with this Iranian immigrant population will be presented through the lens of self psychology and a new perspective about the effects on the sense of self of young immigrant Iranian females will be discussed.

Everyday Indivisibility: How Exclusive Religious Practices Explain Variation in Subnational Violence Outcomes

This project explores the puzzle of religious violence variation. Religious actors initiate conflict at a higher rate than their secular counterparts, last longer, are more deadly, and are less prone to negotiated termination. Yet the legacy of religious peacemakers on the reduction of violence is undeniable. Under what conditions does religion contribute to escalated violence and under what conditions does it contribute to peace? I argue that more intense everyday practices of group members, or high levels of orthopraxy, create dispositional indivisibilities that make violence a natural alternative to bargaining. Subnational armed groups with members whose practices are exclusive and isolating bind together through ritual practice, limit the acceptable decisions of leaders, and have prolonged timeframes, all of which result in higher levels of intensity, intransigence and resolve during violent conflict. The theory challenges both instrumentalist and constructivist understandings of social identity and violence. To support this argument, I construct an original cross-national data-set that employs ethnographic data on micro-level religious practices for 724 subnational armed groups in both civil wars and terror campaigns. Using this data, I build an explanatory “religious practice index” for each observation and examine its relationship with conflict outcomes. Findings suggest that exclusive practice groups fight significantly longer with more intensity and negotiate less. I also apply the practice model to qualitative cases. Fieldwork in the West Bank and Sierra Leone reveals that groups with more exclusive religious practicing membership are principle contributors to violence, whereas those with inclusive practices can contribute to peace. The project concludes with a discussion about several avenues for future research and identifies the practical policy applications to better identify and combat religious extremism.

New Middle East Cold War: Saudi Arabia and Iran's Rivalry

The competing powers of Saudi Arabia and Iran continue to redress and reverse the strategic imbalance and direction of the Middle East’s regional politics. The 1979 Iranian Revolution catapulted these two states into an embittered rivalry. The fall of Saddam Hussein following the 2003 U.S. led invasion, the establishment of a Shi’ite Iraq and the 2011 Arab Uprisings have further inflamed tensions between Saudi Arabia and Iran. Iran and Saudi Arabia have not confronted each other militarily, but rather have divided the region into two armed camps on the basis of political and religious ideology in seeking regional allies and promulgating sectarianism as they continue to exploit the region’s weak states in a series of proxy wars ranging from conflicts in Iraq to Lebanon. The Saudi-Iranian strategic and geopolitical rivalry is further complicated by a religious and ideological rivalry, as tensions represent two opposing aspirations for Islamic leadership with two vastly differing political systems. The conflict is between Saudi Arabia, representing Sunni Islam via Wahhabism, and Iran, representing Shi’ite Islam through Khomeinism. The nature of the Saudi-Iranian rivalry has led many Middle East experts to identify their rivalry as a “New Middle East Cold War.” The Saudi-Iranian rivalry has important implications for regional stability and U.S. national security interests. Therefore, this thesis seeks to address the question: Is a cold war framework applicable when analyzing the Saudi Arabian and Iranian relationship?

Invisible Suffering: Practitioner Reflections on Peacebuilding Programs with Youth Exposed to Traumatic Stressors in Intergroup Conflict

For decades, the international community has recognized that youth are some of the most vulnerable to mental and emotional distress within the intractable and cyclical nature of identity-based violent conflict. Exposure to traumatic stressors within these intergroup conflicts poses unique risks not only to the neurological and social development of youth, but also to the capacities of youth to fully participate in peacebuilding interventions. The peacebuilding field has yet to strongly consider how traumatic stress affects dynamics within programs for youth and how these programs may need to modify expectations of youth’s cognitive, social, and emotional functioning to account for the traumatic dimensions of political and social violence. Through a qualitative analysis of practitioner reflections gathered from an online survey distributed worldwide, this study explores how practitioners conceptualize and approach issues of traumatic stress in peacebuilding programs focused on youth in conflict-affected contexts. The objective is to identify the working assumptions undergirding practitioner conceptualizations and approaches to traumatic stress and gaps in trauma interventions in peacebuilding programs for youth. The implications of these findings will support efforts to enhance trauma-sensitive peacebuilding practice by revisiting and reconsidering preexisting norms.

Athlete Perceptions of Intra-Group Conflict in Sport Teams

The study of conflict has been of primary interest in various fields such as organisational psychology for decades (e.g. Barki & Hartwick, 2004). In sport psychology, however, conflict research has been almost nonexistent (Lavoi, 2007) with few exceptions (e.g. Holt et al., 2012; Sullivan & Feltz, 2001). The importance of understanding conflict in sport and in groups, however, has been acknowledged because it has potentially serious implications for group outcomes (Lavoi, 2007). The present study investigated competitive sport athletes’ perceptions of intra-group conflict in sport. Ten intercollegiate athletes: (N=5 males, N=5 females; Mage=25.00, SD=2.87) participated in semi-structured interviews. Athletes perceived the nature of conflict to manifest itself in several ways including: (a) disagreements; (b) negative emotions; and (c) interference/antagonistic behaviors. In addition, conflict episodes were perceived to arise in task and social situations. The findings are discussed in terms of their contributions to current perspectives on intra-group conflict in sport.

The EU’s Sanctions against Syria: Conflict Management by Other Means. Security Policy Brief No. 38

Since May 2011, the EU has launched one of its most far reaching and sophisticated sanctions operations in support of the protests against the current regime in Syria. The present brief examines the measures wielded by the EU, its expected impact and its implications for the EU’s relations with its global partners. While seriously undermined by the lack of support of Russia, the sanctions are having a noticeable economic impact. Yet, the choice of measures is ill-suited to stop the bloodshed. The sanctions have also served to (re)define partnerships with other powers, both in the Middle-East and globally.

Castles in the sand: Mali and the demise of the EU’s Common Security and Defence Policy. CEPS Commentary, 28 January 2013

The threat posed by the crisis in Mali is direct, multidimensional and without regard to geographical proximity or historical and colonial heritage, writes Giovanni Faleg. France’s solitary intervention in Mali and the EU’s absence there raise two important questions for the future of the EU’s supposedly ‘Common’ Security and Defence Policy. The first has to do with the crisis itself; its nature and the threat posed by the terrorist groups and militias that are being countered by French armed forces. The second concerns the causes and implications of yet another example of the EU’s inability to take responsibility for security matters in its neighbourhood and beyond.

spotlight europe #2013/02-February 2012. Syria: from rebellion to all-out war

The situation in Syria at the beginning of 2013 could hardly be worse. Dead, wounded, refugees, a humanitarian disaster. President Assad is destroying his country and waging war against his own people. Russia and Iran back the regime. The West wants regime change without intervening militarily. The political opposition is now more united but overwhelmed with the situation at hand. The armed resistance, partially dominated by Jihadists, is difficult to size up.
