OBJECTIVE: The current study examines multiple empirically based perspectives (i.e., child, caregiver, and clinician) of behavior and functioning as they contribute to the clinical and psychosocial profile of children (aged 5 to 17.5 years) with reported histories of sexual abuse.METHOD: A large, multi-site data set of children referred into Comprehensive Community Mental Health Services both with and without reported histories of sexual abuse, was examined. Seven hundred and fifty-nine children with a reported history of sexual abuse were compared to 2722 without such a history on caregiver and child reported behavior, clinician rated functioning, diagnosis, demographic variables, and life challenges.RESULTS: The multiple perspectives contributed unique and specific information to regression models: caregiver-reported behavior contributed information about externalizing behavior while child-reported behavior added information about internalizing behavior and clinician ratings about self-harmful behavior. Children with reported histories of sexual abuse were also more likely to be female, Caucasian, and have reported histories of life challenges (e.g., physical abuse, substance use, running away). Child sexual abuse was associated with higher rates of depression and anxiety diagnoses, and lower rates of substance abuse, conduct, and attention deficit disorder diagnoses.CONCLUSIONS: The findings indicate that the profile of children entering into Comprehensive Community Mental Health Services with reported histories of sexual abuse, as compared to those without such histories, is complex and best understood via multiple perspectives. Caregiver, child and clinician rated information, when taken together, provide a comprehensive clinical and psychosocial profile around which to plan and implement individualized service plans.  相似文献

In two experiments, visual and auditory memory was tested for good and for poor readers from the upper elementary grades. Under experimenter-blind conditions, no reading group differences existed for single mode presentation in recognition frequency or recognition latency. With a multimodal presentation, latencies for poor readers were similar to those for the single mode presentation. Good readers, however, had significantly faster latencies with multiple input. Generally, results supported dual coding and self-terminating memory search hypotheses for previously encoded stimuli. Implications of the latency differences between reader groups were discussed with respect to the reading process and reading theory.  相似文献

For over 70 years Annemarie Roeper was able to breathe new life into many aspects of giftedness and gifted education. Capturing the magic of such a charismatic and visionary leader is a challenge. However, stories and storytelling provide a pathway into the narrative of Annemarie’s life as it evolved from young adulthood to elderhood. This article provides the lessons learned during a long-standing friendship and insights into her multidimensional personality.  相似文献

Zusammenfassung Der Topos Bildungsungleichheit hat in der jüngsten Zeit eine Renaissance erfahren. Wie im Anschluss an den so genannten Sputnik-Schock und die Diskussionen der 1960er-bis 70er-Jahre wird durch den PISA-Schock die Frage nach der Qualit?t von Bildung erneut virulent. Gleichzeitig jedoch scheint die heutige bildungstheoretische Debatte zu eingeengt. Sie reduziert sich auf institutionalisierte schulische Bildung und vernachl?ssigt die zentrale Bedeutung au?erschulischer Bildungsprozesse, die sozialstrukturell variieren. So lassen sich aufgrund der — allerdings trotz sozialwissenschaftlicher Dauerbeobachtungen bis heute leider dünnen — Forschungsbasis deutliche Differenzen in milieuspezifischen Bildungsstrategien von Heranwachsenden und ihren Eltern feststellen. In Familie und Gleichaltrigengruppe herrschen demnach erfahrungsbezogene Bildungsinhalte und Strategien vor, die mit den in der Schule dominierenden Leistungs- und Qualifikationsanforderungen auf sehr unterschiedliche Weise zusammentreffen. Die vorgelegte mesotheoretische Bestimmung von Bildungsstrategien weist auf M?glichkeiten einer differenzierten Analyse von Bildungsprozessen hin, die an die makrostrukturellen Pr?missen des Systems sozialer Ungleichheit ebenso anschlussf?hig ist wie an mikrostrukturelle, lebensweltliche Erfahrungsbezüge der Schülerinnern und Schüler.
Summary Milieu-specific Educational Strategies in Families and Peer Groups “Educational disadvantage” is experiencing a renaissance as a topic of educational debate. Just as following the so-called Sputnik-Shock and discussions in the ’60s and ’70s, PISA has renewed the debate on the quality of education. At the same time, the perspective of current educational theory seems too narrow. It focuses on institutionalized school education and overlooks the central importance of educational processes outside of the school, which vary according to social structure. Despite continuous observations within this field, scientific research is weaker than might be expected. However, differences in milieu-specific strategies for education are clearly identifiable between young people and their parents. We propose that experience-based educational content and strategies predominate in both families and peer groups, and that these coincide with the achievements- and qualifications-based educational demands within schools in quite different ways. The following meso-theoretic investigation of educational strategies points to the potential of analyses, which can integrate both the macro-structural conditions of systems of inequality and the experiential, micro-structural reference points of pupils.

A dearth of research has investigated the language preference of bilingual childhood populations and its subsequent relationship to reading skills. The current study evaluated how a sequential bilingual student's choice of language, in a particular environmental context, predicted reading ability in English and Spanish. The participants were Latino children ranging in age from 7 years, 5 months, to 11 years, 6 months, with 43% born in the United States. Results showed a relationship between a child's higher English language preference for media and for communication with others outside the family and better reading skills in English. Language preference differences predicted reading abilities better for English than for Spanish. Results suggested that sequential bilingual children's language preference may be a useful marker of English language (second language [L2]) facility and use that is related to their reading proficiency or influences the development of English reading skills in such bilingual children in the United States. © 2007 Wiley Periodicals, Inc.

ObjectiveTo examine the relationship between the use of preventive software on the home computer and unwanted exposure to sexual material online.MethodsThe Youth Internet Safety Survey-2 was a national, RDD telephone survey conducted in March–June 2005. Eight hundred households (one caregiver and one child between the ages of 10 and 17 years) with home Internet access answered questions pertaining to Internet prevention activities in the household and adolescent behaviors and exposures online.ResultsUnwanted exposure to sexual material occurred in 32% of youth in homes with pop-up/spam blockers and 25% of youth in homes with filtering, blocking, or monitoring software on the home computer, compared to 43% of households without preventive software installed on the home computer. Among otherwise similar youth, pop-up/spam blockers installed on the home computer were significantly associated with 59% lower odds of reporting unwanted exposure to sexual material on the home computer; and filtering, blocking, or monitoring software was significantly associated with 65% lower odds. When data were stratified by youth sex, associations between preventive software and unwanted exposure were similar for boys and girls. When stratified by age, preventive software was associated with significantly reduced risk of unwanted exposure for 10–12-year olds and 13–15-year olds, but not for 16–17-year olds.ConclusionAlthough these correlational analyses are far from providing conclusive evidence that preventive software protects children from unwanted exposure to sexual material online, findings suggest that caregivers of boys and girls 15 years of age and younger who want to reduce the likelihood of unwanted exposure to sexual material on the home computer should consider including preventive software—especially filtering, blocking, or monitoring software—in their Internet safety plan.Practice implicationsPractitioners should partner with caregivers in developing an Internet safety plan, including proactive caregiver-youth discussions about expected Internet behavior appropriate for their household.  相似文献

Currently, very little is known about the impact of short- or long-haul air travel on the sleep and wellbeing of wheelchair basketball athletes. Eleven national wheelchair basketball athletes wore actigraphy monitors prior, during, and after air travel to the United Kingdom. Upon arrival, participants rated their subjective jet-lag, fatigue, and vigor. Individuals traveled to the United Kingdom from different locations in Australia, the United States, and Europe and were categorised according to travel length [LONG (up to 30.2 h) or SHORT (up to 6.5 h)]. Linear mixed models determined effects of travel length on sleep and subjective ratings of jet-lag, fatigue, and vigor. During competition, subjective fatigue and jet-lag were substantially higher (ES = 0.73; ±0.77) and (ES = 0.57; ±0.60), subjective vigor was lower (ES = 1.94; ±0.72), and get-up time was earlier (ES = 0.57; ±0.60) for LONG when compared to SHORT. Travelling greater distances by airplane had a larger effect on subjective ratings of jet-lag, fatigue and vigor, rather than sleep. Irrespective of travel group, sleep and subjective responses were compromised, reflecting the travel requirements, competition-mediated influences, and/or due to a change in environment.  相似文献

Back pain is a worldwide health problem, adding a tremendous burden to modern societies. However, little information on back health is available in China, even though a quarter of the world’s population is Chinese. To enhance knowledge in this area, we designed and initiated the Hangzhou Lumbar Spine Study, which is a cross-sectional study of a general sample of mainland Chinese with focusing on disc degeneration, Modic changes, endplate lesions, and back pain. The study consists of a structured questionnaire to measure back pain history and lifetime exposure to suspected risk factors, magnetic resonance imaging of the lumbar spine, bone mineral density study of the spine and hip, and DNA sample analysis. Here we briefly introduce the study methodology, report the test-retest reliability of the questionnaire, and describe the cohort profile to date. Since May 2014, 301 randomly selected subjects (male/female, 122/179; mean age, 51.0 years; range, 20–87 years) have been recruited. Tests-retests of the questionnaire, completed by 40 participants, revealed good reliability. To our knowledge, the Hangzhou Lumbar Spine Study is the first population-based epidemiological study conducted to characterize lumbar spinal phenotypes and back pain, their interaction, and their associations with lifetime environmental exposure, in mainland Chinese. Epidemiological information obtained from a reliable questionnaire, magnetic resonance (MR) imaging data, dual energy X-ray absorptiometry (DXA) measurements, and DNA analysis may serve as a valuable reference for future studies on back health, particularly for mainland Chinese.  相似文献
