While many child maltreatment victims suffer serious negative emotional sequelae, others do surprisingly well. Resilience in children is a relative concept which can change over time and is affected by environment and genetics. Resilience is fostered by protective factors which ameliorate or alter a child's response to the hazards of maltreatment that usually predispose to maladaptive outcome. Personal characteristics or skills that may foster resilience include (1) rapid responsivity to danger; (2) precocious maturity; (3) dissociation of affect; (4) information seeking; (5) formation and utilization of relationships for survival; (6) positive projective anticipation; (7) decisive risk taking; (8) the conviction of being loved; (9) idealization of an aggressor's competence; (10) cognitive restructuring of painful experiences; (11) altruism; and (12) optimism and hope. There are also generic life circumstances, such as having access to good health, educational, and social welfare services, that foster resilience in children regardless of the specific nature of the stressor. Additionally, there may be abuse-specific protective factors in the environment. Examples might include the quick and full acknowledgment of an offender regarding abuse, or timeliness and permanence of legal actions affecting a child's custody. The life stories of three well-known survivors of various forms of child maltreatment illustrate how protective factors contribute to resilience. A caution is noted regarding how personal characteristics developed for survival may become maladaptive if overused and/or not given up when the stressor no longer exists. Characterological problems are most likely to develop when a child's life circumstances fail to change and the environment never becomes secure. 相似文献

Increased awareness of the problem of child sexual abuse has resulted in increasing numbers of children presenting to professionals for the evaluation of possible sexual victimization. A multidisciplinary project to develop professionals' knowledge and skills in the identification and evaluation of possible victims is described. The program focused on the child as a victim and emphasized developmental perspectives with regard to identification, interviewing children, the medical examination, and children in the legal system. Fifty-one medical and social work professionals from ten Indiana counties attended the program and responded to questionnaires about their experience and knowledge. Of 40 (78%) respondents, 63% had had no previous training in the medical evaluation for child sexual abuse. Child protective workers referred alleged victims primarily to the child's regular physician (37%) or emergency room (31%) for medical examination. Knowledge about child sexual abuse improved significantly at two weeks postsymposium (p = .001) and remained improved at six months postsymposium (p less than .02). These original participants have subsequently organized similar multidisciplinary programs in their local communities for medical, social, law enforcement, and legal professionals; thus, they have been "seeds" for further educational and cooperative efforts throughout the state. 相似文献

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula. 相似文献

This study examined cultural reflections online of audience comments on social network sites regarding vocal talent shows in China and the United States. The study applied dimensions of cross culture to investigate audience comments on the official social networking sites of The Voice of China and The Voice. Findings reflect Hofstede’s dimensions as applied to social media and illustrate how individuals alter their “local” cultural norms in the new media environment. The study specifically enhances the exploration of cultural manifestations in cyberspace, which fewer cross-cultural studies have researched. 相似文献

摘要:今天的美国有1 400万的癌症存活者,其中的很多存活者中都接受了多种治疗,包括手术、放疗、化疗、靶向治疗等。这些治疗能够延长生存时间,但同时也会带来很多急慢性的副作用,危害健康,影响生活质量。体力活动(PA)与癌症生存这一领域发展迅速,主要研究PA对癌症患者的影响。基于该领域的研究进展,提出了以下10大研究问题:1)PA能够降低癌症复发风险、和/或提高存活吗?2)PA能够影响癌症治疗决策、完成率、和/或患者对治疗的反应吗?3)癌症存活者的最佳运动处方是什么?4)静坐少动行为对癌症存活者有何影响?5)癌症存活者最有效的体力活动干预方案是什么?6)哪些癌症会影响病人对PA的反应?7)癌症存活者进行体力活动时需要注意的安全问题有哪些?8)哪些具体的癌症症状可以由PA解决?9)对于癌症晚期患者,体力活动还有何作用?10)如何将体力活动研究结果转化到临床和社区肿瘤实践中来?上述问题的回答至关重要,这不仅关系到体力活动和癌症存活这一研究领域的发展,更重要的是,能够为每年数百万新诊断为癌症的病人、正在接受癌症治疗的病人、治疗结束处于恢复中的病人或是那些正在与晚期癌症抗争的病人带来福音。 相似文献

Fostering College-Going Expectations of Immigrant Students Through the Sympathetic Touch of School Leadership 总被引:1,自引:0,他引:1
Daniel D. Liou 《Multicultural Perspectives》2016,18(2):82-90
This article intends to support the efforts of administrators, teachers, and community activists to center race, equity, and anti-deficit perspectives within the practice of school leadership. By drawing upon methods of critical race studies, and Du Bois's 1935 concept of the sympathetic touch, the author provides examples of anti-deficit approaches to sympathetic leadership in a large, diverse high school in California. Through reflections and recollections upon this case study, the author underscores ways for school leaders to formulate the conditions for college-going expectations for low-income immigrant students. This retrospective account includes concrete leadership examples, political strategies, and scenarios to illuminate the relevance and utilities of the sympathetic touch in educational leadership. In effect, the article calls for school leaders to harness anti-deficit and anti-oppressive mindsets in the work of inclusion, equity, and social justice. 相似文献
