A matched cohort comparison of a criminal justice system's response to child sexual abuse: a profile of perpetrators

OBJECTIVE: This study was undertaken to examine whether alleged child sexual abuse perpetrators are handled differently by the courts than other alleged felony perpetrators. Comparisons were made from the time of prosecutorial case acceptance through prosecution to sentencing, with emphasis on judicial and prosecutorial decision-making and plea-bargaining. METHOD: Data were retrospectively abstracted on the entire defendant population of cases of sexual abuse of children and adolescents (ages 2-17) over a 5-year period. Using a case-flow analysis, comparisons were made between a child sexual abuse cohort and a cohort of matched felony cases from a single jurisdiction. RESULTS: Three important findings emerged. First, compared to other felons, abuse perpetrators were employed, had been married, were mostly European American, and were older than 30 years of age. Second, in the abuse cohort, as many as 14% had a previous sexual or violent record compared to 2% in the comparison group. Third, similar percentages of perpetrators in both groups were released on their own recognizance, had the charges against them dropped, and were found guilty. As well, no differences between groups were found in the proportion of individuals sentenced to jail, probation, counseling, or work release. CONCLUSIONS: Although the treatment of perpetrators of child sexual abuse was similar to the treatment of perpetrators of other felonies, the profile of the child abuse perpetrator was quite different. Knowledge about this profile may impact prosecution or treatment and recidivism rates, to the extent that recidivism is related to characteristics of the abuse perpetrator.     

Central Coherence Theory and the interpretation of picture materials: toward an assessment of autistic spectrum disorder

Central Coherence Theory ( Frith, 1989 ; Happe, 1994a ) may account for the piecemeal style of information processing characteristic of people with autistic spectrum disorder (ASD). This style of processing was observed during language and communication assessments of pupils with ASD. A consistent pattern in the types of these responses emerged, such that it was possible to devise a framework to categorise them.
This article investigates the responses of two groups of eight pupils matched on the basis of gender and verbal ability: i) pupils with a diagnosis of ASD, and ii) pupils without identified difficulties. They were presented with a range of picture materials and their responses were placed within a framework of seven response categories. It was felt that the types of errors made by the two groups differed both quantitatively and qualitatively, and that the type and extent of the errors made by the pupils with ASD were largely attributable to the presence of weak central coherence.
Despite the presence of some limitations in the way the investigation was conducted, it was concluded that these methods might contribute toward the assessment and differential diagnosis of ASD.     

Teacher perspectives on partnerships on families of children with autism

The success of students with disabilities in school and community largely relies on productive family professional partnerships (FPPs). The Individuals with Disabilities Education Act (IDEA, 2004) recognises the importance of family collaboration to student success by mandating that parents be involved in the Individualised Education Plan (IEP) process as full team members. While several previous studies examined the perspectives of parents of children with disabilities on partnerships with educators, less research exists on teacher perspectives on family professional collaborations. Additionally, there are even fewer studies that focus on teacher perspectives on partnerships with parents of children with autism, a disability category which continues to increase in prevalence. The present study contributes to the literature by examining teacher perspectives on factors that build and hinder positive partnerships with families of children with autism. Researchers surveyed 25 Special Education teachers and conducted additional individual interviews and open-ended questionnaires to examine teachers' first-hand experiences. Findings identified four common themes that educators felt helped and hindered collaborative relationships with families. Study results may lead to the development of specific family professional collaboration strategies that can be implemented and discussed in school districts, teacher trainings, pre-service teacher education programs and family workshops.     

Native american related materials in elementary science instruction

The low achievement of Native American students, as measured by standardized tests, results from a number of factors, including the lack of cultural relevance of curriculum materials used in their instruction. Using a pretest–posttest control group design, Native American students in Bureau of Indian Affairs schools in Grades 4–8 who were taught science using culturally relevant materials achieved significantly higher and displayed a significantly more positive attitude toward Native Americans and science than comparable students who were taught science without the culturally relevant materials. It is suggested that when educators of Native Americans teach science, they should use materials that incorporate frequent reference to Native Americans and science.     

The Impact of Viewer Perceptions of Media Personae and Viewer Characteristics on the Strength,Enjoyment, and Satisfaction of Parasocial Relationships

Using a cross-sectional survey design (N = 338), we measured the impact of viewer perceptions of media personae and viewer characteristics on the strength, enjoyment, and satisfaction of parasocial relationships. Strength, enjoyment, and satisfaction of parasocial relationships were strongest with characters that viewers like that are perceived to be similar to the viewer or someone they know in real life. However, the strength and enjoyment of parasocial relationships decreased when the persona was perceived to be similar to either the viewer or someone they know in real life and the viewer was high on attachment anxiety, attachment avoidance, or loneliness. Limitations and implications are discussed.     

Launching the Virtual Academic Center: Issues and Challenges in Innovation

In October 2010, the University of Southern California School of Social Work entered the online education environment with the launch of the first national web-based MSW program. After an initial enrollment of 80 students, in just 3 years this state-of-the-art MSW, offered in a technology-advanced synchronous and asynchronous format, has generated an enrollment of 2,000 students residing in 38 states. The development and rapid growth of the Virtual Academic Center has not been without significant challenges, the most substantial of which has been the creation of a national field education program. This paper describes the MSW courses taught in the online environment, and pedagogical hurdles faced in order to maintain the educational quality that is the hallmark of the School's campus-based MSW program.     

Describing the plastic deformation of aluminium softball bats

Hollow aluminium bats were introduced over 30 years ago to provide improved durability over wooden bats. Since their introduction, however, interest in hollow bats has focused almost exclusively around their hitting performance. The aim of this study was to take advantage of the progress that has been made in predicting bat performance using finite elements and apply it to describe bat durability. Accordingly, the plastic deformation from a ball impact of a single-wall aluminum bat was numerically modelled. The bat deformation from the finite-element analysis was then compared with experiment using a high-speed bat test machine. The ball was modelled as an isotropic, homogeneous, viscoelastic sphere. The viscoelastic parameters of the ball model were found from instrumented, high-speed, rigid-wall ball impacts. The rigid-wall ball impacts were modelled numerically and showed good agreement with the experimentally obtained response. The strain response of the combined bat-ball model was verified with a strain-gauged bat at intermediate ball impact speeds in the elastic range. The strain response of the bat-ball model exhibited positive correlation with the experimental measurements. High-speed bat-ball impacts were performed experimentally and simulated numerically at increasing impact speeds which induced correspondingly increased dent sizes in the bat. The plastic deformation from the numerical model found good agreement with experiment provided the aluminium work hardening and strain rate effects were appropriately described. The inclusion of strain rate effects was shown to have a significant effect on the bat deformations produced in the finite-element simulations. They also helped explain the existence of high bat stresses found in many performance models.     

Measurement of teacher performance: A study in instrument development

The procedures used to produce a research-based teaching evaluation system, containing low-inference indicators of effective and ineffective teacher behavior, included instrument development, content validation, and field testing. An extensive reliability study produced estimates for three types of consistency: intercoder agreement (r = 0.85), stability across teaching situations r = 0.86, and discriminant reliability among teachers (r = 0.79). The norming component of the study conducted in 45 schools, generated over 1200 observations of current teacher practice at all grade levels and in various subject areas. The results indicated the substantially generic nature of these behaviors; only grade level and instructional method (interactive, lecture, and independent seatwork) produced meaningful differences among groups of teachers. In addition, the average teacher used most of the effective behaviors (70%), and a few of the ineffective behaviors (8%) during observation. These results support the instrument's value in teacher training, remediation, and evaluation.
