The development of an effective response to the abuse of children in out-of-home care 总被引:1,自引:0,他引:1
The placement of children in foster or residential care does not ensure that children will be safe from abuse or neglect. The incidence of out-of-home maltreatment, especially sexual exploitation and abuse, has given rise to new community expectations and legislation which has placed the protection of children in alternate care squarely in the hands of the child protective system. These investigations differ in purpose and scope from familial investigations, and the current protective system is without adequate preparation, policy, and procedures to perform them. This paper discusses the differences in familial and out-of-home care investigations in relation to identification and reporting, assessing risk factors in the initial report, evidence gathering, essential components of the investigation, levels of culpability and corrective action approaches. The authors suggest that specialized investigation units may be more suited to these investigations than traditional child protective services. 相似文献

Learners studying mechanical or technical processes via dynamic visualizations often fail to build an accurate mental representation
of the system’s movements. Based on embodied theories of cognition assuming that action, perception, and cognition are closely
intertwined, this paper proposes that the learning effectiveness of dynamic visualizations could be enhanced by grounding
the movements of the presentation in people’s own bodily experiences during learning. We discuss recent research on embodied
cognition and provide specific strategies for how the body can be used to ground movements during the learning process: (1)
making or observing gestures, (2) manipulating and interacting with objects, (3) using body metaphors, and (4) using eye movements
as retrieval cues. Implications for the design of dynamic visualizations as well as directions for future research are presented. 相似文献

Technology was integrated into service-learning activities to create an interactive teaching method for undergraduate students
at a large research institution. Chemistry students at the University of Central Florida partnered with high school students
at Crooms Academy of Information Technology in interactive service learning projects. The projects allowed UCF students to
teach newly acquired content knowledge and build upon course lecture and lab exercises. Activities utilized the web-conferencing
tool Adobe Connect Pro to enable interaction with high school students, many of whom have limited access to supplemental educational
opportunities due to low socioeconomic status. Seventy chemistry I students created lessons to clarify high school students’
misconceptions through the use of refutational texts. In addition, 21 UCF students enrolled in the chemistry II laboratory
course acted as virtual lab partners with Crooms students in an interactive guided inquiry experiment focused on chemical
kinetics. An overview of project’s design, implementation, and assessments are detailed in the case study and serve as a model
for future community partnerships. Emerging technologies are emphasized as well as a suggested set of best practices for future
projects. 相似文献

Part II of “Reclaiming Kindergarten” continues the discussion related to responding to the crisis in today’s kindergarten.
In Part II, two policy questions are posed, the answers to which seek to respond to this continuing crisis. The questions
center on issues related to engaging families in kindergarten and the need to consider a new early childhood paradigm where
kindergarten is part of a continuous and seamless educational experience spanning prekindergarten through third grade. As
in Part I, examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten
classroom. 相似文献

Multicultural policy in South Korea faces variants of challenges endemic to multiculturalism. These challenges are “dilemmas
of difference,” “variable terms of inclusion,” and “legitimacy.” In Korea, these challenges arise in a setting in which ethnic
diversity is of relatively recent origin, an ideology of ethnic homogeneity is prevalent, and official multicultural policy
is limited in its reach to those who are designated as “multicultural families,” that is families in which one spouse is Korean
and the other an immigrant, usually the wife, and their offspring. The exclusion of migrant workers and their families from
Korea’s multicultural framework poses a core contradiction in Korean multicultural policies. This contradiction must be resolved
if multiculturalism in education and other spheres is to promote equality and provide a foundation for national integration
on terms that are equitable to the diverse constituents of Korean society. Inevitably, this will require a redefinition of
what it means to “be Korean.” Even if multicultural policies fall short in their immediate effects on those toward whom they
are directed, multiculturalism represents a significant shift in the discourse of Korean identity and will be terrain on which
the status of diverse groups in Korea will be contested. 相似文献

OBJECTIVE: This study examined specific aspects of child sexual abuse in relation to symptom severity among hospitalized patients diagnosed with bulimia nervosa. METHOD: Participants were 45 hospitalized bulimic women who reported a history of child sexual abuse. Structured interviews were conducted in order to obtain detailed information regarding specific features of the abusive event(s). Participants also completed instruments that measured depression and eating pathology. RESULTS: There were no significant differences in severity of depression or eating disturbance among women reporting differing abusive experiences including intrafamilial versus extrafamilial abuse, abuse with or without the use of physical force, one versus multiple incidents, early abuse versus abuse occurring after age 14, contact versus noncontact abuse, disclosed versus undisclosed, and combined physical/sexual abuse versus sexual abuse alone. CONCLUSION: The specific characteristics of child sexual abuse are not related to the level of symptomatology for hospitalized bulimic patients. This study suggests that differences in the nature of the abuse may not be as important as the fact that the abuse occurred in the first place. 相似文献

Meta-analysis was used to review the results of 25 studies that compared the classroom behavior of children and adolescents with learning disabilities (LD) to children without learning disabilities. The data were analyzed from several different methodological perspectives. Results showed that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities compared to their nondisabled peers in each of five overall areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Both observational and teacher rating data demonstrated these differences. Effect sizes for both groups of studies seemed to cluster around 1 standard deviation, suggesting noticeable and educationally significant impairment in the behavior of children with disabilities. Analysis of grade-level effect sizes suggests some explanation for the large number of referrals often witnessed during the elementary school years. Educational implications of these behavioral differences in terms of implications for mainstreaming are discussed. 相似文献
