The purpose of this study was to develop and verify the Index of Science Reading Awareness (ISRA) based on a model of an efficient, successful interactive-constructive science reader and three independent metacognitive awareness domains. Several researchers have noted the need for efficient, reliable, and valid measures of metacognition. ISRA data collected on 532 students (Grades 4–8) were analyzed using factor analyses, linear structural modeling, and analyses of variance (ANOVAs) to help verify the model and the test. The factor analyses and linear structural modeling indicated that these data did not support the assumption about the three independent metacognitive awareness domains, but suggested that the model and the test were structured around the design features of science reading, science text, and science reading strategies. One-way ANOVAs indicated significant, predicted reading ability and gender differences but unexpected grade-level differences. The composite metacognitive awareness data indicated that most Grade 4–8 students have surface knowledge about science reading, science text, and science reading strategies, and indicated specific targets for explicit science reading instruction. © 1998 John Wiley & Sons, Inc.

This paper examines an application for a franchise license in Australia's professional rugby league competition, the National Rugby League (NRL). Frooman's (1999) typology of stakeholder influence strategies is used to analyse the negotiation of resource relationships between a Gold Coast franchise bid team and its key stakeholders. Primary data came from 12 interviews with nine key actors in the bid process; these were buttressed by secondary data. Frooman's typology provided a useful heuristic, but did not fully account for the critical role of firm legitimacy in stakeholders’ choice of influence strategies. The bid team negotiated stakeholders’ initial direct withholding strategies by creating access to the intangible resource of legitimacy. This subsequently provided access to material resources such as finance, a new stadium, and, ultimately, a franchise license. The findings are of note to practitioners and scholars interested professional sport and stakeholder theory.  相似文献

The teachers' role in the integration of science and technology studies within the recent educational reform in Israeli junior high schools was addressed within a case study. Eight science teachers and three technology teachers participated in in‐service training courses and received individual tutoring. Data were obtained through school visits, interviews with management, teachers, and tutors. Pupils' performance on a science‐technology project was assessed by an achievement test and a questionnaire. Science teachers preferred to extend their content knowledge and didactic skills in science. Technology teachers lacked basic scientific knowledge. A realistic aim is to expose the science teacher to the field of technology, and the technology teacher to the realm of science, to the extent that will enable him or her to cooperate with the teacher in the parallel domain, rather than train a teacher to teach both. © 1999 John Wiley & Sons, Inc.

Across the United States, children with behavioral and emotional problems receive one of a variety of labels if they are determined eligible for special education services. Labels like SED, EBD, and BD can result in lowered or negative expectations that others have for these children. This study investigated the effects of label, child's gender and race, child's educational placement, and availability of definitional information on prognostic judgments for children with behavior problems. Three‐hundred‐sixty‐three undergraduate students enrolled in teacher education courses read a vignette and completed a prognostic outlook questionnaire. The questionnaire items asked for judgments about the likelihood of further behavioral disruption, the likelihood of developing and maintaining adequate interpersonal relationships, and requested an estimate of overall adjustment of the child. The vignette described an elementary school child with behavior problems and its content was held constant. Gender (boy vs. girl), race (African American vs. Caucasian), educational placement (receiving special education services full‐time through inclusion vs. self‐contained), diagnostic label (BD vs. EBD vs. SED) and definition of the disorders (present vs. absent) were varied. There was a label × race × placement interaction and a label × definition interaction for the behavioral disruptiveness dependent measure. Under the inclusion condition White children who had the SED or EBD label were rated to be significantly more likely to be disruptive than children with the BD label. For the 2‐way interaction when no definitional information was given children who had the SED label were rated more likely to be disruptive than children who had either the EBD or BD labels. There was also a significant gender × race × definition interaction on the overall adjustment measure. However, post hoc contrasts were not significant and no conclusions were drawn other than that the effect was minimal. There was a significant main effect of gender on the interpersonal relationships variable. Girls were judged as significantly more likely to develop appropriate interpersonal relationships with others than were boys. No other significant effects were noted. © 1999 John Wiley & Sons, Inc.  相似文献

Cooperation in innovation activities: The importance of partners   总被引:1,自引:0,他引:1  
This paper analyses the importance of cooperation partners for the development of innovation activities. We contribute to the literature on cooperation in innovation activities that seeks to identify the characteristics differentiating cooperative from non-cooperative firms by proposing a different approach to this problem. We distinguish firms according to their evaluation of cooperation partners in the development of innovation activities. We apply a probit selection model to account for the firm's decision to cooperate (or not). The data we use come from the Portuguese Third Community Innovation Survey. Our estimation results show that firms from high-technological industries, with higher levels of absorptive capacity and of innovation investment, who give importance to incoming spillovers management, and who cooperate with firms from the same group or with suppliers, place greater value on cooperation partners in the innovation process. Additionally, we also find that the factors influencing the importance attributed to cooperation activities are different from the ones behind the decision to cooperate.  相似文献

International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of discussion among academics and practitioners. Most research in this field focuses on knowledge sharing activities of MNC subsidiaries. Relatively little is known about their capabilities for protecting valuable knowledge from spilling over to host country competitors. We extend this stream of research by investigating both formal protection strategies (e.g. patenting) as well as strategic ones (secrecy, lead time, complex design). We conceptualize the breadth of firm's knowledge protection strategies and relate it to the particular situation of MNC subsidiaries. Moreover, we argue that their approaches differ with regard to host country challenges and opportunities. We address these issues empirically, based on a harmonized survey of innovation activities of more than 1800 firms located in Portugal and Germany. We find evidence that MNCs prefer broader sets of knowledge protection strategies in a host country with fewer opportunities for knowledge sourcing (Portugal). In Germany, though, they opt for narrower sets of knowledge protection strategies if they invest in innovation activities themselves. We deduce that these results are due to a need for reciprocity in knowledge exchanges to benefit fully from promising host country knowledge flows.  相似文献

Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection.  相似文献

New applications of genomics techniques in soil ecology may provide people with fresh insights into the richness of microbial life forms and natural methods to build on the "self-cleaning capacity" of soils. Because genetic modification might also be involved, this paper examines people's judgments about some applications, using a theory on the promotion- or prevention-orientations that they may associate with interventions in the natural world. A prevention-oriented way of thinking was hypothesized to correspond with a preference for more restrictions on a GM application, unless the person appreciates the application's benefits for nature restoration. Survey data agreed with the hypotheses and clarified the way in which people may talk about "nature knows best" or "nature needs a little help".  相似文献
