同辈调解在美国校园欺凌中的运用探究

美国中小学校园欺凌的防治经历了从"报应性正义"到"修复性正义"的理论变迁.作为修复性正义的典型措施,同辈调解遵循"由学生主导,为学生服务"的理念,将校园欺凌置于学生冲突框架之下,旨在通过同辈调解员化解同辈冲突,从而实现防治校园欺凌的目标.经过40余年的发展,美国同辈调解在规划设计、遴选模式、培训体系和调解流程等方面已相当成熟,并且在减少校园冲突和欺凌现象,改善校园学习氛围,以及提升学生冲突解决能力等方面卓有成效.美国同辈调解在实践中也无可避免地存在着调解能力、适用范围、资金支持等方面的问题与局限.     

Preventing boys' problems in schools through psychoeducational programming: A call to action

Controversy currently exists on whether boys are in crises and, if so, what to do about it.

Legal Aspects of Preventing Problem Behavior

Changes to the Individuals with Disabilities Education Improvement Act (Public Law 108-446) (now known as the Individuals with Disabilities Education Act of 2004 Individuals with Disabilities Education Improvement Act of 2004, H.R. 1350 (passed both houses of Congress 11/19/04; signed by President Bush 12/3/04) [Google Scholar]: IDEA) mandated new requirements for providing discipline to students with disabilities. These changes led to simplified procedures when students with disabilities commit infractions of the school code. A review of potential legal dilemmas, however, challenges the simplicity of the revised procedures and may actually underscore new legal entanglements to parents and school officials. We discuss what we know about discipline and reasons for an interest in discipline applications, potential legal complications resulting from the reauthorized IDEA, and implications of prevention strategies for students with disabilities demonstrating problem behaviors.

防止倒吸的装置

1 隔离式 图1、图2是利用导管口与液体互不接触,即使液面上方压强减小,也不会倒吸,缺点是吸收不够充分;图3是利用气体逸出后再溶于水,而气体难溶于导管出口处的下层液体,既保证了气体的吸收,又不影响导气管内压强,该装置若用于洗气时,应将烧杯改为洗气瓶.

Preventing alcohol-exposed pregnancy among American-Indian youth

Research has determined that the prevention of alcohol-exposed pregnancies (AEP) must occur preconceptually, either by reducing alcohol intake in women planning pregnancy or at risk for becoming pregnant, or by preventing pregnancy in women drinking at risky levels. One such AEP prevention programme with non-pregnant American-Indian (AI) women is the Oglala Sioux Tribe (OST) Changing High-risk alcohOl use and Increasing Contraception Effectiveness Study (CHOICES) Programme, which shows promise in reducing AEP risk in AI women aged 18 or older. A community needs assessment was conducted with key informant interviews and focus groups with an emphasis on how to expand OST CHOICES. To identify relevant inter-related themes, a content analysis was conducted on qualitative feedback from the focus groups and interviews. Altogether, key informant interviews were completed with 25 health and social service professionals. Eight focus groups were held with 58 AI participants, including adult women of child-bearing age, elder women, and adult men. Several sub-themes regarding the prevention of AEP with youth were identified, expanding the OST CHOICES curriculum into the schools, and the role of family and culture within AEP prevention.
