General analytical solution for stress intensity factor of a hypocycloid hole with many cusps in an infinite plate

In this article, the problem for the determination of the displacement functions and the stress intensity factors (SIFs) around a boundary of a hypocycloid hole with cusps in an infinite elastic plate subject to normal and shear stresses are presented. A hole with cusps (hypocycloid) is mapped onto a unit circle and the modified complex potential is used for solving the relevant boundary value problems. An analytical solution for the SIF of a hypocycloid hole is obtained. For a special case, our results agree with others.     

Childhood Exposure to Community and Domestic Violence: Prevalence,Risk Factors and Posttraumatic Outcomes in a South African Student Sample

The effects of exposure to direct and vicarious community and domestic violence on the posttraumatic adjustment of 323 South African students were examined. Data were collected using self-administered questionnaires, with the relationship between exposure to violence and posttraumatic outcomes being explored using binomial logistic regression analyses. Two hundred and sixty-two participants (81 %) reported that they had been exposed to some form of interpersonal violence during childhood. An analysis of risk factors for exposure to violence indicated that males were more than twice as likely as females to have experienced victimization by a community member. Direct exposure to domestic violence was the only form of violence which was found to be associated with Posttraumatic Stress Disorder (PTSD). Among participants who had experienced direct domestic violence, clinically significant levels of PTSD were significantly predicted by both gender (being female) and by abuse chronicity.     

A Grammar of Love

Abstract

Recently researchers in the family therapy field have encouraged a focus on aspects of therapy common across all models that are important to therapeutic change. The purpose of this study was to build on the “common factors” literature by exploring clients' perspectives of what was useful to their therapeutic experience. Quantitative and qualitative measures were used to collect data from 41 clients who participated in therapy at a university-based family therapy clinic. Quantitative results indicated that therapeutic relationship, client motivation, extratherapeutic factors, and hope and expectancy accounted for 49% of the variance of clients' perception of change and 73% of the variance of clients' perceptions of therapy helpfulness. Qualitative results indicated the therapeutic relationship to be the most helpful aspect of clients' therapeutic experience.     

Inclusion

Summary

In a growing number of schools in the United States, it now is possible to walk into elementary, middle, and secondary classrooms and observe students who could be identified as having moderate and severe cognitive, physical, and emotional disabilities successfully receiving their education together with similar-aged classmates who have no identified special education needs (Falvey, 1995; Lipsky & Gartner, 1997; Schrag, 1998; Villa & Thousand, 1995). This practice of welcoming, valuing, and supporting the diverse learning needs of all students in shared general education environments is referred to as inclusive education, inclusive schooling, or inclusion. This article examines inclusive education along a number of dimensions. First, the evolution of the inclusion moment is briefly examined. After the construct of “severe disability” is considered in the context of inclusive education, various rationale for inclusion are examined along with outcome data, legislation, and legal and U.S. Department of Education decisions which forward inclusive policy. Next, eight factors most frequently associated with successful inclusive education are described and discussed. In describing the factors, examples are provided of specific assessment, planning, and communication processes that support the inclusion of students with intensive cognitive, physical, and emotional disabilities. The article ends with a discussion of the implications of inclusive education for a 21st Century democracy.     

Dynamics of Peer Victimization in Early Adolescence

ABSTRACT

This study addressed the stability of victimization across four consecutive years from Grades 4 to 7, and the concurrent correlates, short-term consequences, and predictors of victimization in early adolescence. Participants were 600 students (49% girls) enrolled in 10 elementary schools in Grades 4-5 and 2 middle schools in Grades 6-7 in an ethnically diverse school system. Data collection included peer nominations, self-reports, and teacher reports in each year. Victimization was highly stable across all years, including the transition from elementary to middle school. Both concurrent and short-term consequences showed that victimized 6th graders, especially girls, experienced significantly greater maladaptive outcomes than their nonvictim counterparts. For both genders, risk factors for adolescent victimization included externalizing and internalizing behaviors, while protective factors included academic and peer sociability elements. Implications for prevention and intervention are discussed.     

Social Services Workers and Workplace Violence

Researchers and workplace violence experts have cited risk factors that theoretically increase the likelihood that individuals will experience workplace violence. Those include working alone, contact with the public, traveling to dangerous areas, as well as other factors. By the very nature of what social services workers do, many encounter these risk factors on a regular basis. Using national data, trends in workplace violence experienced by social services workers are examined, and comparisons are made between the rates of workplace violence among similar workgroups. Results suggest that social services workers are nearly six times more likely than other workers to experience workplace violence. In the discussion, attention is given to strategies to prevent violence against social services workers.     

Characteristics of Male Batterers in Treatment

Abstract

This article presents information on the characteristics of a clinical population of male perpetrators of intimate partner violence (IPV) court-ordered for batterers' treatment, and how these characteristics co-varied with treatment attrition. The average demographic profile of male batterers in a midwestern treatment program that met present-day treatment guidelines was similar to that found in other studies. In addition, relationship length and status, alcohol/drug use, self-reports of past treatment and mental health issues, and self-report of witnessing or experiencing violence within the home during childhood was also similar. Batterers' self-reports of their own violent behavior were found to vary by data collection technique, with face-to-face interviews eliciting greater admission of violent behavior than paper-and-pencil questionnaires. However, the only predictors of successful treatment outcome were living arrangement at the time of treatment and racial category. Implications of these findings are discussed, and “local effects” program evaluation approaches are suggested.     

Women Experiencing Psychological Abuse: Are They a Homogenous Group?

Dichotomizing women as “abused” versus “not abused” assumes that any psychological maltreatment results in similar outcomes. A national sample of women in conflictual relationships completed an online survey. Women with no incidence (N = 33), the lowest quartile (N = 86), and the top quartile (N = 81) of psychological maltreatment demonstrated significant differences in reactions to the maltreatment, mental health indicators, personality variables, perceived harm, problematic relationship schemas, and response styles. Women with no psychological abuse and women in the lowest quartile produced similar scores that were typically distinct from the top-quartile women. Effective treatment of women with lower amounts of psychological abuse might not require a unique intervention likely necessary for women experiencing much psychological abuse.     

Caring for Carers in the Aftermath of Trauma

The potential impact on psychological well-being of working in the caring professions in the aftermath of trauma and disaster has been recognized for many years, with terms such as burnout, compassion fatigue, and vicarious traumatization coined to describe stress-related conditions. Although prevalent, these conditions do not affect all workers in the field. Various studies have investigated potential risk and protective factors. It is argued that the outcomes of this research should be used to guide practical interventions in the workplace designed to minimize stress-related problems. A framework that incorporates interventions at the primary, secondary, and tertiary prevention levels is outlined, and research investigating the efficacy of interventions at each of these levels is recommended.     

Perceptions of Juvenile Offenders Who Were Abused as Children

Should a history of child abuse be taken into consideration when a juvenile offender is punished? Although some research shows that child abuse is used as a mitigating factor for juvenile offenders (i.e., elicits less punitive sentences), surveys of juvenile court officials reveal that it is considered an aggravating factor. Specifically, in controlled mock jury studies in which child abuse is experimentally manipulated, child abuse elicits less punitive sentences. In contrast, child abuse elicits more punitive sentences in a nonexperimentally controlled environment—the juvenile justice system. This article provides a comprehensive literature review to explain these conflicting bodies of research by considering factors that naturally covary with childhood abuse: chaotic family environment, mental health problems, behavioral problems, and school problems.
