Frank–Read sources and the yield of anisotropic cubic crystals

Frank–Read sources are among the most important mechanisms of dislocation multiplication, and their operation signals the onset of yield in crystals. We show that the critical stress required to initiate dislocation production falls dramatically at high-elastic anisotropy, irrespective of the mean shear modulus. We hence predict the yield stress of crystals to fall dramatically as their anisotropy increases. This behaviour is consistent with the severe plastic softening observed in α-iron and ferritic steels as the α ? γ martensitic phase transition is approached, a temperature regime of crucial importance for structural steels designed for use in future nuclear applications.     

In God we trust? Organised religion and personal beliefs as resources and coping strategies,and their implications for health in parents with a child on the autistic spectrum

Abstract

This paper is part of a larger study looking at the impact on 60 families of having a child with autistic spectrum disorder. Here the roles played by organised reliagion and personal belief and their relationship with health status are explored. The DSM-IV, and the Childhood Autism Rating Scale, were used to confirm diagnosis and measure the severity of autism. A questionnaire was used to investigate support from organised religion and personal beliefs. The General Health Questionnaire was used to assess health. Participants reported receiving significantly less support from their organised religion than from their personal belief. Higher scores on support from personal belief, particularly the use of prayer, were associated with better health.     

Evidence-based medicine,psychoanalysis and psychotherapy

SUMMARY

The scientific status of psychoanalysis is a matter of importance to both theorists and clinicians in psychiatry. The empirical evidence for both the theory and the practice of psychodynamic practice is much greater than is generally recognised. There is strong evidence for the effectiveness of psychoanalysis and psychoanalytically oriented therapy. the future of psychoanalysis depends on this evidence. We will discuss both the evidence and reasons why it is overlooked in certain quarters, and review the developing neuro-cognitive understanding of the mechanisms that underlie psychoanalytical processes.     

Depressive symptoms over time in women partners of men with and without alcohol problems

In a sample of 202 adult women and their families, the authors examined the effects of their male partners' alcohol problems and antisociality, the women's alcohol problems and antisociality, family conflict, and offspring behavioral problems on the women's depressive symptoms over a 3-year period. The women's antisociality and alcohol problems were more strongly related to family conflict, offspring behavioral problems, and the women's depressive symptoms than were the men's antisociality and alcohol problems. The women's antisociality and family conflict most strongly predicted increases in the women's depressive symptoms over time. In addition, family conflict mediated the effects of maternal antisociality on the women's depressive symptoms.     

Mobilizing Residents for Action: The Role of Small Wins and Strategic Supports

Yes we can! is a community-building initiative funded by the W. K. Kellogg Foundation that aims to improve educational and economic outcomes in Battle Creek, Michigan by mobilizing low-income communities and resident leaders and building their capacity to influence the decisions and policies that impact their lives. This paper describes the strategies pursued during the first phase of this initiative to foster resident mobilization by building small wins within the neighborhood. Primarily through a neighborhood-based mini-grant program and staff supports to encourage collective action, Yes we can! has started to increase levels of resident mobilization within the seven economically distressed neighborhoods that initially partnered with the W. K. Kellogg Foundation on this effort. The specific programming components and how they were implemented as well as the initial successes experienced are described. Lessons learned are discussed.     

The (un)reasonableness of reporting: antecedents and consequences of reporting sexual harassment

This study places the reporting of sexual harassment within an integrated model of the sexual harassment process. Two structural models were developed and tested in a sample (N = 6,417) of male and female military personnel. The 1st model identifies determinants and effects of reporting; reporting did not improve--and at times worsened--job, psychological, and health outcomes. The authors argue that organizational responses to reports (i.e., organizational remedies, organizational minimization, and retaliation) as well as procedural satisfaction can account for these negative effects. The 2nd model examines these mediating mechanisms; results suggest that these mediators, and not reporting itself, are the source of the negative effects of reporting. Organizational and legal implications of these findings are discussed.     

Developmental trajectories of disruptive behavior problems among sons of alcoholics: effects of parent psychopathology,family conflict,and child undercontrol

This study examined trajectories of disruptive behavior problems from preschool to early adolescence in 302 boys from a community-recruited sample of high-risk families. Growth modeling showed that paternal alcoholism was associated with elevated levels of sons' disruptive behavior problems. Family conflict predicted more disruptive behaviors at school entry and a slower rate of decline in such problems. Parent antisocial personality disorder (ASPD) exacerbated the effects of high preschool levels of sons' undercontrol on level of disruptive behaviors at school entry; this effect became progressively stronger across time. Low levels of undercontrol protected sons of ASPD parents from experiencing heightened levels of disruptive behaviors both at school entry and increasingly as sons grew older. Implications for subsequent maladjustment are discussed.     

RAPE MYTHS. In Review

Theories of sexual aggression and victimization have increasingly emphasized the role of rape myths in the perpetuation of sexual assault. Rape myths are attitudes and generally false beliefs about rape that are widely and persistently held, and that serve to deny and justify male sexual aggression against women. Acceptance of such myths has been assessed with a number of measures, and investigators have examined its relationship with numerous variables and interventions. Although there has been extensive research in this area, definitions, terminology, and measures of rape myth acceptance (RMA) continue to lack adequate theoretical and psychometric precision. Despite such criticisms, we emphasize that the significance of this type of research cannot be overstated because it has immense potential for the understanding of sexual assault. The present article offers a theory-based definition of rape myths, reviews and critiques the literature on rape myth acceptance, and suggests directions for future research. In particular we argue that such work must include the development and application of improved measures, with more concern for the theoretical and methodological issues unique to this field.
