Over the past three decades, U.S. science and technology funding agencies have increasingly supported large-scale, centralized, block grant-based research projects that often span multiple disciplines and institutions. This trend has developed at such a rate that research focused on understanding the management of these new collaborative models has largely not kept pace. We use two case studies of large-scale, multi-disciplinary collaborations to develop an institutional framework that illuminates the relationships among (a) the epistemic norms of the disciplines represented in the collaboration, (b) the organizational structure of these collaborations, and (c) the inter-institutional collaboration success.The results of our case study analysis demonstrate that large-scale, multi-discipline, inter-institutional collaborations need a relatively high level of development in either (1) the epistemic development of the disciplines involved in the collaboration or (2) the organizational structure of the collaboration. We argue that the domain (i.e. epistemic or organizational) that provides the highest level of institutionalization is the one that organizes the “rules” of the collaboration.  相似文献

The world-wide use of digital storage and communications devices is increasing the need to make texts available in multiple languages. In this article we explore the possibility of storing a compressed form of a translated version of a text, taking advantage of the availability of the original text. The original text provides some of the semantic content of the text that is to be compressed, and therefore makes it possible for compression to be more efficient than if that information were not available. We begin with an experiment to evaluate the information content of a text when a parallel translation is available. This is achieved by having human subjects guess texts letter by letter, with and without a parallel translation. The perceived information content of a text can be determined from the way subjects make their guesses. The design and results of this experiment are described. The main conclusion is that while the text is considerably more predictable with the aid of a parallel translation, there is a surprising amount of information introduced by the translation. Insights obtained from this experiment are then applied in the design of a mechanical system for compressing parallel texts. The system stores one translation of a text intact, and then compresses further translations of the text with the aid of the original. The method described is able to compress texts significantly better than is possible without the aid of a parallel text. Aspects of the design are also applicable to future compressors that might take advantage of the semantic content of a text to obtain better compression.  相似文献

According to the Communicative Ecology Model of Successful Aging (CEMSA), how people talk about age can have implications for how they cope with aging later in life. However, most research on communication and successful aging has focused on older adults. In this study, we use latent class analysis to profile how younger adults (age 18–39) communicate about aging and examine how these profiles relate to their attitudes toward aging (affect, efficacy, anxiety, and perceptions of successful aging). Consistent with past research on older adults, we found three distinct profiles of communication behavior (disengaged, engaged, and bantering). An engaged profile was clearly associated with the most positive attitudes toward aging, while a disengaged profile was associated with the least positive attitudes. These findings suggest that patterns of talk about aging may start early in life, underscoring the importance of studying communication about aging across the lifespan.  相似文献

This study investigated the relationship between responsibility attribution and tendency to report child sexual abuse among practicing psychologists. Two hundred ninety-five licensed psychologists from two states completed vignettes in which the sex of the child and the father's admission or denial of alleged sexual abuse were systematically manipulated. Subjects assigned relative percentages of responsibility to the father, mother, child, and society for the abuse and indicated their tendency to report and their level of confidence that abuse was occurring. Results indicated a significant effect for responsibility to the mother which varied as a function of the father's response to the allegation of abuse. Mothers were blamed significantly more for the abuse when the father denied being abusive. Responsibility attribution did not predict reporting, while confidence in the occurrence of abuse did. Also, sex differences were found among participants where male subjects assigned significantly more responsibility to the abusive father than female participants, and the females blamed the mother more than the males. Results are discussed in the context of previous research on responsibility attribution in child abuse.  相似文献

The role that affective states play in learning was investigated from the perspective of a constructivist learning framework. We observed six different affect states (frustration, boredom, flow, confusion, eureka and neutral) that potentially occur during the process of learning introductory computer literacy with AutoTutor, an intelligent tutoring system with tutorial dialogue in natural language. Observational analyses revealed significant relationships between learning and the affective states of boredom, flow and confusion. The positive correlation between confusion and learning is consistent with a model that assumes that cognitive disequilibrium is one precursor to deep learning. The findings that learning correlates negatively with boredom and positively with flow are consistent with predictions from Csikszentmihalyi's analysis of flow experiences.  相似文献

This article traces the roots of narrative research in the social sciences and education, then centers on ‘story constellations,’ a version of narrative inquiry that uncovers teachers’ knowledge of school reform in context. A fluid form of investigation that unfolds in a three-dimensional inquiry space, story constellations consists of a flexible matrix of paired narratives that are broadened, burrowed, and restoried over time. The adaptability of this narrative inquiry approach is then made visible through introducing four story constellations separately, then laying sketches of the individual story constellations side-by-side. When analyzed in a conjoined fashion, these sketches illustrate how the particularities of place and human agency in the living of school reform played out differently in differing school contexts, despite the fact that the four school sites had one story of reform in common. In the end result, the illustrations demonstrate how the use of the malleable approach drew distinctive story constellations to the surface, spotlighting teachers’ knowledge of school reform as it developed in context over time. In this way, ‘story constellations’ as a method and as a form of inquiry is illuminated.  相似文献
