In response to a growing number of requests to help reunify parents and children separated by allegations of child abuse, we developed a model for intervention informed by clinical experience, feedback from clients and professionals, and insights from a growing body of interdisciplinary literature. This article presents a retrospective analysis of 29 intrafamilial cases describing the intervention, outcomes, and problems presented by these challenging situations. The safety and protection of the child was the paramount consideration in determining success, whether or not reunification was achieved. Using informal follow‐up data, 24 of the 29 cases were categorized as successful, 21 resulted in full or partial reunification, and 3 cases resulted in the voluntary or court‐ordered withdrawal of an accused father believed to pose a risk to the child. In 5 cases, the nonaccused parent thwarted efforts at reunification, and the case returned to the court of relevant jurisdiction.  相似文献

Community Service by High School Students: A Cure for Civic Ills?   总被引:1,自引:0,他引:1  
In response to what some see as a crisis in civic attitudes and participation, there has been a reinvigorated effort to involve high school students in school-based community activities and in less formal, volunteer community service. Yet little is known about the extent of participation or its effects. Using a nationally representative sample of 9th–12th graders from 1996, we document a high participation rate but also note that many students perform service only once or twice a year and in limited capacities. Participation rates are related to certain student, family, and school characteristics; school policies are also significant, though arranging but not requiring participation may be the key. Participation appears to stimulate greater political knowledge, more political discussions with parents, enhanced participation skills, and higher political efficacy, but not more tolerance of diversity.  相似文献

The politics of identity draws on postmodernist rejections of the universals of liberalism in theorizing the claims of individuals and groups on the political community. An alternative grounding of claims is provided by Hegel's concept of Sittlichkeit , the idea of the ethical instantiation of the citizen in the community. Sittlichkeit shares the self-determinist claims of identity-based models of community. It shares in particular their rejection of the heteronomy of antecedent principles of rights and justice. This paper is a study of the operationalizing of Sittlichkeit in Indonesian education for citizenship under the New Order implementation of the state ideology. It is intended to show the collectivist as well as the pluralist potential of normative settlements produced by 'perspectival dialogism', and consequently the importance of owning the derivation of the politics of identity from liberalism, when pluralism is the desired outcome .  相似文献

Group psychotherapy with disturbed undersocialized adolescents requires modification of traditional group psychotherapy methods. The effectiveness of a structured, brief video-tape feedback and discussion on group psychotherapy process with this population was studied by an analysis of detailed ratings of each statement, or process unit; in randomly selected videotapes from a control and experimental group during a nine-month period. Significant differences in level of intimacy of verbal content and in frequency of feedback about behavior in content indicate that this technique is effective in facilitating group psychotherapy goals.Received Ed.D. from University of Kentucky.

Sexual risk taking among female delinquents represents a significant public health problem. Research is needed to understand the pathways leading to sexual risk taking among this population. This study sought to address this issue by identifying and testing two pathways from child maltreatment to non-condom use among 329 White and 484 African American female adolescent detainees: a relational pathway and a substance use coping pathway. The relational pathway indicated that child maltreatment would be related to non-condom use via depressive self-concept and condom use self-efficacy. The substance use coping pathway suggested that depressive self-concept and alcohol-based expectancies for sexual enhancement would mediate the relationship between child maltreatment and non-condom use. As hypothesized, the relational pathway variables were associated with one another in the expected directions; however, evidence of mediation was not found. Support for mediation was found for the substance use coping pathway. Exploratory across group comparison analysis indicated that the relational pathway was significant for White girls whereas the substance use coping pathway was significant for African American girls. Limitations and implications for future research are discussed.  相似文献

Primary cardiac tumors are rare, with an autopsy incidence of 0.03%. Seventy-nine percent to 85% of primary cardiac tumors are benign, and of the benign tumors, cardiac hemangiomas account for 5-10% of cases. Most cardiac hemangiomas are asymptomatic and are discovered incidentally at autopsy, or by echocardiography, computerized tomography, or magnetic resonance imaging. We report a case of sudden death owing to cardiac hemangioma in a 22-year-old woman who collapsed while shopping and became unresponsive. The autopsy revealed a hemorrhagic mass on the surface of the right atrium which was infiltrating and replacing the wall of the right atrium; histopathological examination confirmed the tumor was a cavernous hemangioma. Fewer than 20 cases of right atrial cavernous hemangiomas have been reported in English literature, emphasizing the rarity of our case.  相似文献

This case represents unusual findings of elevated bupivacaine and tryptase concentrations following local anesthetic, bupivacaine, administered as a scalene nerve block for elective rotator cuff repair surgery. Following bupivacaine injection, the patient exhibited almost immediate seizure activity, bradycardia, and cardiac arrest. Resuscitative efforts including cardiopulmonary bypass restored a cardiac rhythm. However, the clinical medical status of the patient progressively declined and he died 7 h following administration of the local anesthetic. Autopsy revealed several abnormalities of the heart including cardiomegaly, myocardial bridging, and lipomatous hypertrophy of the intraatrial septum, which may have contributed to bradycardia and arrhythmia. Postmortem toxicology results revealed elevated bupivacaine and tryptase concentrations. Elevated postmortem bupivacaine concentrations 7 h following administration and abrupt onset of seizures indicate unintentional intravascular injection instead of nerve and tissue infiltration. An elevated postmortem tryptase concentration points to the possibility of a hypersensitivity reaction to bupivacaine.  相似文献
