This chapter provides a context for the concept of not-knowing, including a discussion of how the concept was framed. The experience of not-knowing in professional youth work is framed in relationship to other concepts explored by the social work and therapeutic literature (including vicarious trauma, helplessness, secondary trauma, and burnout), as well as those offered by the limited youth work and nursing literature discussing similar concepts (disruption and hurt, suffering, commitment in spite of conflict, and the struggle to go along when you do not believe). The standing of youth work in the professions and its own struggles to professionalize are explored, with attention to how not-knowing affects and is affected by these efforts.  相似文献

The Indian residential school system in Canada was established to assimilate Aboriginal children into mainstream society by removing the “Indian within them.” In the past 20 years survivors of the schools have come forward with stories of physical and sexual abuse perpetrated against them by staff. However, what is significantly less spoken of is the abuse which occurred between students. The Aboriginal Healing Foundation recently held a small gathering of survivors, Elders, advocates, and researchers to discuss ways to bring this issue into the open. This article comes out of the discussions held at the gathering. Within the article we offer a conceptualization of the dynamics and processes of student to student abuse within the Indian residential schools in Canada with the hope that it will encourage a deeper discussion of this issue.  相似文献

Children and youth who have experienced foster care or orphanage-rearing have often experienced complex developmental trauma, demonstrating an interactive set of psychological and behavioral issues. Trust-Based Relational Intervention (TBRI) is a therapeutic model that trains caregivers to provide effective support and treatment for at-risk children. TBRI has been applied in orphanages, courts, residential treatment facilities, group homes, foster and adoptive homes, churches, and schools. It has been used effectively with children and youth of all ages and all risk levels. This article provides the research base for TBRI and examples of how it is applied.  相似文献

从近年查处的腐败犯罪的情况来看,"一把手"占三分之一左右.预防"一把手"腐败犯罪,一是要建立和健全选拔机制,选拔高素质的人才担任"一把手";二是要建立和健全教育机制,在思想上筑牢防腐拒变的思想长城;三是要建立和健全办事制度,防止"一把手"专权和滥用权力;四是要建立和健全监督制度对"一把手"实行有效的监督.  相似文献

Although some authors have suggested that women batterers may really be self-defending victims, to date, no research has been initiated to empirically support this assertion. This paper describes the design and outcomes of a research project that investigated the similarities and differences between women adjudicated as domestic violence batterers and women identified as domestic violence victims. Findings indicated group similarities in the areas of exposure to violence and social service utilization. Although both groups reported high levels of trauma symptomology, victim scores were significantly higher.  相似文献

The determination of perimortem trauma is important for forensic anthropologists. Characteristics of bone fractures such as sharp edges, presence of fracture lines, the shape of the broken ends, fracture surface morphology, fracture angle on the Z-axis, and butterfly fractures are said to differentiate perimortem from postmortem trauma. A Drop Weight Impact Test Machine was used to break 76 deer femora of various ages since death. The results of this study suggest that the characteristics listed above are unreliable at differentiating a perimortem fracture from a postmortem fracture in a forensic case. There are, however, statistically significant differences between fresh bones broken less than 4 days old and dry bones broken 44 days or 1 year old after death.  相似文献

In cases of acute fatal child abuse, certain injuries, including cutaneous blunt force trauma, skull fractures, subdural hematomas, intra-abdominal hemorrhage, and retinal hemorrhages are common and well described in the pediatric and forensic literature. These gross findings at autopsy, when taken into consideration with scene investigation and interviews with caregivers, may indicate both a clear manner and cause of death. In such cases, the discovery of additional pathologic changes attributable to older abusive injuries helps support a conclusion of death due to inflicted trauma. We discuss four cases of fatal child abuse in which acute blunt force abdominal trauma was the cause of death. In each of these cases, careful examination with proper sectioning and microscopy of select abdominal tissues revealed that the acute tissue trauma was superimposed on a background of older, healing injury. This older trauma was characterized by classic histologic elements of tissue repair, including fibroblast proliferation, early scar formation, increased vascularity, and hemosiderin-laden macrophages. Iron and trichrome stains were used to confirm the presence of hemosiderin and fibrosis in all four cases, but the recognition of fibroblast proliferation and a reactive vascular pattern was best seen on routine hematoxylin and eosin stains. The gross and microscopic autopsy findings, along with available investigative information, established the diagnosis of chronic physical abuse.  相似文献

Pediatric rib head fractures are typically described as “posterior” or “costovertebral,” terms lacking specificity. To resolve this issue, a scheme was developed to describe the location of rib head fractures observed in a pediatric forensic population. The scheme uses three anatomical landmarks, terminus (tip), tubercle, and costovertebral articular surface to divide the rib head into two subregions, costovertebral and costotransverse. Examples of five cases of infants with rib head fractures are presented using this scheme. Forty‐eight rib head fractures were observed in these infants with the following frequencies: 56% (three infants) at the terminus; 21% (three infants) in the costovertebral subregion; 21% (one infant) at the costovertebral articular facet; and 2% (one infant) in the costotransverse subregion. Due to the small number of cases assessed, statistical analyses could not be performed; however, the data demonstrate the variation in distribution of pediatric rib head fractures.  相似文献
