Child behaviors as a moderator: Examining the relationship between foster parent supports,satisfaction, and intent to continue fostering

Foster parents need access to supports and resources in order to be satisfied with their caregiving role and continue providing foster care services. However, they often experience multiple demands in their role as a substitute caregiver that could lead to stress. Child behaviors especially may be a significant factor when considering sources of strain and may be a potential risk factor for negative outcomes such as dissatisfaction or the decision to discontinue providing foster care. The purpose of this study was to examine whether child disruptive behaviors moderated or influenced the nature or strength of the relationship between foster parent supports and satisfaction as a caregiver as well as intent to continue fostering. The sample consisted of 155 licensed foster caregivers from across the United States. Child behaviors served as a significant moderator between some types of supports and satisfaction. Implications for future research, practice, and policy are discussed.     

A multi-criteria approach for the group assessment of an academic course: A case study

The present paper aims at proposing a structured methodology to evaluate the results of an academic training course addressed to postgraduate students. The evaluation process intends to identify the efficacy of an education course by means of a comparison between the general objectives and the results expected by the students. Since the evaluated aspects by the students, detected by means of questionnaires, are both quantitative and qualitative, the proposed methodology is based on the analytic hierarchy process (AHP). In order to facilitate the evaluation process, answers have been modelled by means of linguistic variables. In particular, different evaluation scales have been used and each one is characterized by different levels associated to different fuzzy numbers.

The Artist Initiative at San Francisco Museum of Modern Art

The Artist Initiative at the San Francisco Museum of Modern Art (SFMOMA) is piloting models for increased collaboration between conservators and curators through joint work with artists. We seek a more integrated, holistic approach to the care and research of our collection. The project, funded by the Andrew W. Mellon Foundation, comprises five robust research engagements that serve the curatorial collecting departments of the museum (Photography, Painting and Sculpture, Media Art, and Architecture and Design). Three of the projects are monographic studies, examining the work of Ellsworth Kelly, Vija Celmins, and Julia Scher in depth, while two more are thematic, exploring modes of displaying digitally-driven design objects, and developing strategies for addressing the problem of color shift common to photographic prints made with experimental materials during the 1970s and 1980s. The Artist Initiative is also charged with developing hybrid working spaces to advance collaborative approaches to collections research at the museum's new downtown campus and at SFMOMA's new Collections Center in South San Francisco. These spaces include the Collections Workroom, a 56?sq?m (600?sq?ft) space that functions as a studio for visiting artists, a conservation laboratory, an interview suite, and a classroom at SFMOMA's downtown campus. At the Collections Center, a 121?sq?m (1300?sq?ft) Mock-Up Gallery has been built as a working model of one of the museum's new galleries. A functional exhibition space, the Mock-Up Gallery is also a venue for interviewing artists, prototyping exhibition formats, and meeting with students, scholars, museum staff, and community members. With the goal of contributing to critical discourses in contemporary art history, art conservation, and public engagement, each of the Artist Initiative projects includes a colloquium that will bring experts from multiple fields together with the featured artists. Thereafter we aim to share our findings widely through public programs and a range of publications, both digitally and in print.     

可行能力贫困:阅读困难群体的实质性特征

[目的/意义] 旨在厘清"阅读困难群体"的研究对象,分析产生阅读困难问题的原因,提出解决这些人阅读困难问题的策略。[方法/过程] 引入经济学中分析贫困问题根源的"可行能力方法"分析阅读困难群体的问题,从人的能力发展的角度考察阅读困难产生的原因,从而提出解决策略。[结果/结论] 可行能力贫困是阅读困难群体的实质性特征,可行能力贫困产生的原因在于阅读困难群体的"内在性"阅读困难、"结构性"阅读困难以及"生命敏感期"的脆弱性。增强阅读困难群体选择的"能力"与"机会"是扩展可行能力的关键,也是未来图书馆解决阅读困难群体问题的方向。     

关怀理论:教师专业成长中不可忽视的内容

诺丁斯的关怀理论是20世纪80年代中期提出,并随着90年代初兴起的“学会关心”这一国际教育思潮而备受关注。它为教师的专业成长提出了一种新的研究视角:彰显教师的非理性精神来挑战传统理性;以学习关怀为出发点而建构学校教育和教师成长的新内容;在关怀实践中提升教师专业成长的责任感与动力。

研究生公选课程分组讨论教学的规则设计、组织与有效实施 ——澳大利亚新南威尔士大学(UNSW)研究生公选课程教学经验的借鉴

澳大利亚新南威尔士大学的教师通过对学生循环提问与交叉提问的方式,事实上组织起了一场以研究生个人为参与主体的课堂讨论,该课堂讨论通过对研究生讨论表现实时计分的方式凝聚了学生课堂注意力,同时也有效控制了讨论秩序,其教学经验值得我国借鉴。然而,由于两国研究生公选课程人数及国民性格的较大差异,澳洲的教学经验不能在国内同类课堂完全直接适用。有必要进行针对性改造、变通。在改造后的分组讨论模式中,由教师实时记录各讨论小组的发言、提问及评论质量,并通过科学的分数构成及相关规则将各小组成员的个人总评成绩进行具体量化,同时通过小组内部及小组之间的双重竞争机制有效保障研究生个人持续性积极参与分组讨论的全部环节。
