Adaptive support for computer-mediated collaboration aims at supporting learners’ collaboration in a way that is tailored
to their actual needs and by fostering their self-regulation, leading to the acquisition of new collaboration skills. This
review gives an example of developing support for a specific collaboration skill: the co-construction of genuinely new knowledge
by drawing collaborative inferences. The review shows how the development of increasingly detailed and accurate collaboration
models and the implementation of an online assessment led toward the development of an effective training with adaptive tutoring
support. In doing so, it outlines and illustrates a sequence of four steps in developing and testing adaptive collaboration
support: deciding which collaboration skill(s) to support; conceptualizing the individual and collaborative activities underlying
the skill; specifying rules for providing adaptive support based on an online assessment of collaboration indicators; and
evaluating adaptive collaboration support. 相似文献

The term ‘hypervideo’ has different interpretations in the scientific literature. The aim of this contribution is to define hypervideo as it is and can be (more optimally) used for teaching and learning purposes. Videos can promote learning by recreating real experiences and dynamic processes, although they do not necessarily enable students to interact with contents and to self-regulate their learning. Hypervideos technically overcome these limitations and add further benefits. However, even though some literature on the topic exists, the concept of hypervideo is not well represented in the scientific community and lends itself to different interpretations. Results show that hypervideo is defined as a dynamic artefact, it should allow navigation control and include additional material; it could also integrate individual or collaborative annotation and automated or manual feedback. So far, most studies have been conducted in artificial settings involving tertiary-level students. Finally, its use is beneficial for students’ learning. 相似文献

As there is still no commonly accepted scale to measure the brand personality of sport teams, the purpose of this study was to develop and validate the Sport Team Personality Scale (STPS) in a professional sport context. The authors conducted a series of studies in the United States and United Kingdom with fans of the English Premier League, Major League Baseball, the National Basketball Association, the National Football League, and the National Hockey League. The STPS contains 18 items that load onto six factors: success, talent, entertainment, dedication, admiration, and care. The authors compared this new scale with existing sport team personality scales and used it to explore team identification and perceptual similarities and differences among teams. Results indicate that teams map along performance (i.e., success and talent) and character (i.e., admiration and care) factors and that the character factor is a more important source of team identification than the performance factor. Taken together, these results illustrate how the STPS can help sport managers position and differentiate teams within a league to improve marketing outcomes. 相似文献

Zusammenfassung Dieser Beitrag gibt einen überblick über unterschiedliche Bildgebungs- und Bildverarbeitungsverfahren,
die heute in den Kliniken verwendet werden. Es wird die gesamte Bildkette von der Bildverarbeitung über
die Bildverbesserung bis hin zur Rekonstruktion und Bildregistrierung beschrieben. Die einzelnen Themenkomplexe
werden dabei aus medizinischer und technischer Sicht diskutiert. Aus den klinischen Anforderungen und den
gesetzlichen Randbedingungen folgen wichtige Grunds?tze für die Architekturkonzepte und den Entwicklungsprozess
medizinischer Bildverarbeitungssysteme.

This paper analyses the role of repeated ties in the high-tech pharmaceutical biotechnology industry, a sector that is characterized by a strong dual market structure. Our most important finding is that previous ties in pairs of large pharmaceutical companies and small biotechnology firms have a negative effect on their subsequent partnering. An explanation for this result is found in the context of understanding the specifics of large-small coalitions in a high-tech dual market structure. Unlike what is known about repeated ties in many other industries, this high-tech dual market structure indicates that R&D partnerships between a small number of very large companies and a large group of dependent, small firms are not characterized by mutual dependence, similarity, or equality. 相似文献

Learners are often overwhelmed by the complexity of realistic learning tasks, but reducing this complexity through traditional Instructional Design (ID) methods jeopardizes the authenticity of the learning experience. To solve this apparent paradox, a two-phase ID model is presented. Phase 1 consists of cognitive task analysis, where a systematic approach to problem solving (SAP) is identified in conjunction with skill decomposition and determination of task complexity. In the subsequent design phase, inductive micro-level sequencing based on the four-component ID model (van Merriënboer, 1997) is applied where worked-out examples and problems accompanied by process worksheets assure the necessary variability of practice. Step size in a multiple-step whole-task approach—needed for the process worksheets—is determined on the basis of estimated part-task complexity. A developmental study of the model is illustrated with examples from the domain of law. 相似文献
