Building Collaborative Capacity in Community Coalitions: A Review and Integrative Framework 总被引:1,自引:0,他引:1
Pennie G. Foster-Fishman Shelby L. Berkowitz David W. Lounsbury Stephanie Jacobson Nicole A. Allen 《American journal of community psychology》2001,29(2):241-261
This article presents the results of a qualitative analysis of 80 articles, chapters, and practitioners' guides focused on collaboration and coalition functioning. The purpose of this review was to develop an integrative framework that captures the core competencies and processes needed within collaborative bodies to facilitate their success. The resulting framework for building collaborative capacity is presented. Four critical levels of collaborative capacity—member capacity, relational capacity, organizational capacity, and programmatic capacity—are described and strategies for building each type are provided. The implications of this model for practitioners and scholars are discussed. 相似文献

应对量表(COPE)测评维度结构研究 总被引:25,自引:3,他引:22
该文旨在对应对量表(COPE)的测评维度结构进行进一步的鉴别分析和验证研究。研究一对736名大学生的应对量表中文修订本(C-COPE)测评数据进行探索性二阶因素分析;研究二根据已有研究关于应对量表测评维度组构模式的不同结论,以及研究一的结果,提出十个假设模型,采用验证性因素分析测试这些模型与另一大学生样本(N:465)测评数据的拟合度。研究结果支持C-COPE八因子斜交模型。该量表如何进一步修订也在文中予以讨论。 相似文献

The accurate interpretation of large numbers of neuropsychological tests within a flexible battery approach is a difficult and sometimes controversial process. We present a statistically based method of interpretation (Rohling's Interpretive Method or RIM) and evaluation of neuropsychological data that allows for varying numbers of tests along a varying number of cognitive domains, yet remains psychometrically based. This method requires informed clinical judgment in that the level of confidence for tests, cognitive domains, and global indices are used as the backdrop for interpretive decisions. Specific procedures for use are presented in a systematic, detailed fashion to allow the interested reader to replicate the method. Two case examples are presented: a straightforward case of cerebrovascular insult and a more complicated case of mixed etiology. Examples include a variety of different neuropsychological tests commonly used in a flexible battery approach. A discussion of the practicality, ease of use, and potential limitations of this method are further presented. 相似文献

We applied functional analysis methodology to the assessment and treatment of 2 individuals' self‐injurious behavior (SIB), which was reported to be occasioned by transitions from one activity or location to another. A structural (task) analysis of activity transitions identified at least three separate components that might influence behavior either alone or in combination: (a) termination of a prechange activity, (b) initiation of a postchange activity, and (c) movement from one location to another. Results of preference and avoidance assessments were used to identify activities to which participants were exposed in varying arrangements during transitions in a functional analysis. Results of 1 participant's functional analysis indicated that his SIB was maintained by avoidance of having to change locations, regardless of the activity terminated prior to the change or the activity initiated following it. The 2nd participant's analysis revealed the same function but also an additional one: avoidance of certain task initiations. This information was used to identify transition contexts during intervention and to design treatment procedures appropriate for a given context and behavioral function. A procedure involving advance notice of an upcoming transition had no effect on SIB, and differential reinforcement of alternative behavior (DRA) had limited effects in the absence of extinction. Sustained decreases in SIB were observed when DRA was combined with extinction and response blocking. Further extensions of functional analysis methodology to the assessment of problem behavior in situations characterized by multiple or protracted stimulus changes are discussed. 相似文献

Although experimental effects typically are evaluated by summarizing levels of responding across time (e.g., calculating the mean levels of problem behavior during 10‐min sessions), these data summaries may obscure important mechanisms that may be responsible for changes in responding. A case study is reported to illustrate alternative methods of data analysis when decreasing trends in responding may be due to increases in response efficiency. 相似文献

A variable-selection heuristic for K-means clustering 总被引:4,自引:0,他引:4
One of the most vexing problems in cluster analysis is the selection and/or weighting of variables in order to include those that truly define cluster structure, while eliminating those that might mask such structure. This paper presents a variable-selection heuristic for nonhierarchical (K-means) cluster analysis based on the adjusted Rand index for measuring cluster recovery. The heuristic was subjected to Monte Carlo testing across more than 2200 datasets with known cluster structure. The results indicate the heuristic is extremely effective at eliminating masking variables. A cluster analysis of real-world financial services data revealed that using the variable-selection heuristic prior to the K-means algorithm resulted in greater cluster stability. 相似文献

为了探讨哪一类别商品的平面广告更适合于采用幽默的诉求方式,研究随机选取160大学生为被试,以16则改编平面广告为实验材料,以广告类型(幽默,非幽默)、商品类别为自变量,以广告评价、广告顺序为协变量,以商品的印象程度、喜爱程度、购买意向为因变量,进行平衡设计实验。结果表明,幽默广告具有较好广告效果,可以提高受众对大宗工具、小奖赏和小工具型商品的记忆;幽默平面广告更适用于低风险、功能性商品,不适用于高风险、享乐性商品。 相似文献
