B J Vander Mey 《Child abuse & neglect》1988,12(1):61-72
The evidence available at this time indicates that male children are more likely to be abused by nonfamily rather than family members. Residing in a neglectful home or a mother-headed household and having previous homosexual contact tend to heighten risk for sexual abuse by nonfamily members. Familial sexual abuse appears related to residence in a home where other siblings are being abused, where the father was a victim of sexual abuse as a child, and where parents suffer myriad personal and social adjustment difficulties. Effects of male child sexual abuse appear to be serious and long lasting. The scant writings available at this time imply that the sexually abused male child experiences a range of adjustment and self-esteem problems as an adult and may be at heightened risk to become a child sexual abuser. 相似文献

This essay examines Green Day's “Jesus of Suburbia” as an artifact and reflection of suburban American punk culture. It looks at how music, lyrics, and the ethos of the performer interact to create a message that fostered identification between speaker and audience by using Sellnow and Sellnow's Langer-based illusion of life perspective. In this case it was found that music can be seen as an effective tool for expressing the suburban punk experience due to its ability to convey both linguistic and emotional content. 相似文献

In response to an invitation to explore the idea that potential guidelines be considered for qualitative inquiry in environmental education research, this article argues that prerequisite understanding of the nature and scope of qualitative inquiry required for such a task will reveal the problem inherent in it. Understanding the diverse complexities, the requisite variety, of qualitative inquiry not only challenges the methodological uniformity necessitated by this task philosophically; it unmasks the epistemological and ontological limits of such an endeavor, however well intentioned. 相似文献

The purpose of this study was to test the directionality of influence between reading comprehension (RC) and print exposure (PE), thereby estimating genetic and environmental effects of this relation. The sample consisted of 910 twins in fourth through ninth grades (Mage = 12.33 years, SD = 1.41) from the Florida Twin Project on Reading, Behavior, and Environment. Using direction-of-causation model in a twin design, results supported a direction of influence running from RC to PE. This relation was underpinned by genetic and environmental factors of RC as well as PE. Implications for reading education are discussed. 相似文献

AbstractIn this article, we share a model of flipped instruction that allowed us to gain a window into our students’ mathematical thinking. We depict how that increased awareness of student thinking shaped our mathematics instruction in productive ways. Drawing on our experiences with students in our own classrooms, we show how flipped instruction can be used to design experiences that help students make sense of mathematics during class sessions. 相似文献

Optical chromatography relies on the balance between the opposing optical and fluid drag forces acting on a particle. A typical configuration involves a loosely focused laser directly counter to the flow of particle-laden fluid passing through a microfluidic device. This equilibrium depends on the intrinsic properties of the particle, including size, shape, and refractive index. As such, uniquely fine separations are possible using this technique. Here, we demonstrate how matching the diameter of a microfluidic flow channel to that of the focusing laser in concert with a unique microfluidic platform can be used as a method to fractionate closely related particles in a mixed sample. This microfluidic network allows for a monodisperse sample of both polystyrene and poly(methyl methacrylate) spheres to be injected, hydrodynamically focused, and completely separated. To test the limit of separation, a mixed polystyrene sample containing two particles varying in diameter by less than 0.5 μm was run in the system. The analysis of the resulting separation sets the framework for continued work to perform ultra-fine separations. 相似文献

Young children with autism spectrum disorder (ASD) are increasingly being included in early childhood classrooms that include typically developing peers and in general education classrooms once they enter school. Many of these learners have the requisite academic skills to be successful, yet their social communication and behavioral challenges often impede their successful inclusion in general education settings. The challenges educators may experience when interpreting and responding to some behaviors exhibited by young students with ASD are explored and analyzed using an illustrative case vignette of a Kindergarten child with ASD. Recommendations for analyzing the communicative function of children’s behavior and for embedding social communication opportunities in inclusive classroom settings are described. 相似文献

The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the covariance among math fluency, untimed math measures, and reading measures. However, roughly two thirds of the variance in math fluency was independent from untimed math measures and reading, including reading fluency. The majority of this independent variance was the result of genetic factors that were longitudinally stable across two measurement occasions. These results suggest that math fluency, although related to other math measures, may also be a genetically distinct dimension of mathematics performance. 相似文献

Objective. This study examined associations among Korean immigrant mothers’ use of praise and encouragement, their acculturation, their children’s socioemotional and behavioral difficulties, and the moderating role of child gender and age. Design. One hundred and twenty Korean immigrant mothers in the United States and their preschool children participated. Maternal praise and encouragement were observed during free-play interactions. Mothers reported their acculturation level, and teachers reported on children’s difficulties. Results. Mothers used process praise most frequently. Higher maternal American acculturation was associated with more use of person and other praise. Higher Korean acculturation was associated with greater use of person praise among younger children, but less use of person praise among older children. Mothers higher in American acculturation used more encouragement with older children only. Maternal encouragement was associated with fewer child difficulties. Conclusion. Korean mothers’ acculturation impacted their use of praise and encouragement, and maternal encouragement may be important for decreasing children’s difficulties. 相似文献
