Prevalence of childhood sexual abuse among incarcerated males in county jail

OBJECTIVE: The current study examined the prevalence and characteristics of childhood sexual abuse in a jailed-based population. METHODOLOGY: A retrospective, self-reported survey was administered over an 8-week period to a random sample of 100 men who were incarcerated in a county jail in Southeastern Texas. The survey included questions about childhood sexual experiences before and after puberty, drug history and use, and sexual risk-taking behaviors. RESULTS: Of the 100 male inmates who participated in this study, 59% reported experiencing some form of sexual abuse before puberty, and all such instances occurred before or at the age of 13 years. The first episode of childhood sexual abuse began at an average age of 9.6 years (SD = 2.4), and ended at an average age of 13.0 years (SD = 2.3). Kissing and touching without intercourse (64%) was the common pattern of sexual abuse experience reported. The total number of perpetrators was 165, with 10% male and 90% female. Friends (n = 72) and family (n = 56) were the most frequent perpetrators. CONCLUSION: Childhood sexual abuse may be more prevalent among inmates than among males in the general population. These results show a high percentage of inmates who report a history of childhood sexual abuse; this rate is higher than those reported by other studies for incarcerated males. The findings support the belief held by professionals in the criminal justice field that a significant number of incarcerated males may have been victims of sexual abuse.     

Testing the double-deficit hypothesis in an adult sample

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants were parents of children referred for evaluation of reading difficulties. Approximately half of all participants reported difficulty learning to read in childhood and a small subset demonstrated ongoing weaknesses in reading. Structural equation modeling results suggest that the double-deficit hypothesis is an accurate model for understanding adult reading achievement. Better reading achievement was associated with better phonological awareness and faster rapid automatized naming in adults. Posthoc analyses indicated that individuals with double deficits had significantly lower reading achievement than individuals with single deficits or no deficits.     

Assessing students' ability to trace matter in dynamic systems in cell biology

College-level biology courses contain many complex processes that are often taught and learned as detailed narratives. These processes can be better understood by perceiving them as dynamic systems that are governed by common fundamental principles. Conservation of matter is such a principle, and thus tracing matter is an essential step in learning to reason about biological processes. We present here multiple-choice questions that measure students' ability and inclination to trace matter through photosynthesis and cellular respiration. Data associated with each question come from students in a large undergraduate biology course that was undergoing a shift in instructional strategy toward making fundamental principles (such as tracing matter) a central theme. We also present findings from interviews with students in the course. Our data indicate that 1) many students are not using tracing matter as a tool to reason about biological processes, 2) students have particular difficulties tracing matter between systems and have a persistent tendency to interconvert matter and energy, and 3) instructional changes seem to be effective in promoting application of the tracing matter principle. Using these items as diagnostic tools allows instructors to be proactive in addressing students' misconceptions and ineffective reasoning.     

Finding related sentence pairs in MEDLINE

We explore the feasibility of automatically identifying sentences in different MEDLINE abstracts that are related in meaning. We compared traditional vector space models with machine learning methods for detecting relatedness, and found that machine learning was superior. The Huber method, a variant of Support Vector Machines which minimizes the modified Huber loss function, achieves 73% precision when the score cutoff is set high enough to identify about one related sentence per abstract on average. We illustrate how an abstract viewed in PubMed might be modified to present the related sentences found in other abstracts by this automatic procedure.     

University of Arkansas for Medical Sciences electronic health record and medical informatics training for undergraduate health professionals

The University of Arkansas for Medical Sciences (UAMS) is planning interprofessional training in electronic health records (EHRs) and medical informatics. Training will be integrated throughout the curricula and will include seminars on broad concepts supplemented with online modules, didactic lectures, and hands-on experiences. Training will prepare future health professionals to use EHRs, evidence-based medicine, medical decision support, and point-of-care tools to reduce errors, improve standards of care, address Health Insurance Portability and Accountability Act requirements and accreditation standards, and promote appropriate documentation to enable data retrieval for clinical research. UAMS will ensure that graduates are ready for the rapidly evolving practice environment created by the HITECH Act.     

Discrepancies in the values of standard atmospheric pressure: the riddle resolved

Over half a century ago, when I took Beginning Physics at university, I was bothered by the anomaly that normal air pressure (which is arbitrary anyhow) was taken to be 1.013250 bar instead of a sensible 1.000000 bar. My professor could not explain why, nor could any of the many other scientists whom I have asked since then. Now in retirement, I have made a laborious search in utterly uncharted territory and discovered the answer.     

Exploring organisational perspectives on implementing educational inclusion in mainstream schools

Achieving equality remains a major challenge in schools globally. In Hong Kong, the current education policy has a core value that all students have the right to learn. Policy-makers and school personnel are struggling to find ways of catering for diverse learning needs in schools. Early in 2006, a self-initiated inclusive educational project has linked one mainstream school and a special school. Their project can be seen as a pioneer in the field of education, for it provides concrete recommendations to other education practitioners on initiating whole-school participation and joint-school partnerships, integrating such collaborations into the culture of the school, and encouraging teachers committed to student voice and engagement. This article records the qualitative case study comprising the teachers' self reports to demonstrate how teachers re-shaped their perceptions, beliefs and behaviours as they developed and implemented a school-based inclusion project. It is expected that the findings of this study will assist educators to further understand present challenges in the school system regarding managing diversity and attaining inclusive education goals. In particular, local schools are now facing the challenge to implement inclusive education.     

Working‐class parents' views of secondary education

Parents of upper‐secondary students in public schools in New South Wales, Australia, gave accounts of their experience of education and their wider thinking about educational issues. Working‐class families are bearers of educational histories which are often difficult or truncated, leaving parents with little familiarity with upper‐secondary or post‐school pathways. General views of education are strongly positive, sometimes diffuse and sometimes articulated, and are by no means narrowly instrumental. A mixture of criticism and praise for teachers responds to current family experiences with schools, parents' views often following the outlines of teachers' own perceptions. A fund of working‐class support for public education has thus survived recent educational upheavals; at the same time, working‐class families very much depend on the service and guidance provided by the schools.     

International graduates’ cross-cultural adjustment: experiences,coping strategies,and suggested programmatic responses

The purpose of the study was to examine the experiences of international graduates to find out how they perceived their new learning environment in Singapore, and to explore the strategies they employed to adjust to, manage and construct meaning out of their learning situation. A qualitative, critical incidents methodology was used in the research. It was found that adjustment for students was most difficult in the first 6 to 12 months from entry into the new cultural context, largely due to the influence of previous educational and cultural experiences on expectations. Four major themes were identified in the student experiences those of marginalisation: student/supervisory relationship, academic/organisational marginalisation, social marginalisation and advantaging. The coping strategies identified were those of self-determination, collegial support and examination strategies. The importance of collegial support as a key coping strategy for international student adjustment was confirmed in the study. Implications arising from the study may inform intervention programmes that are directed to the points of tension identified in students’ experiences.
