Two large independent sources of data, NSF's University Science Statistics Program Integrated Data Base and CHI Research's bibliometric data base, are brought together in a comprehensive study of the relationships among research resources, as measured by R&D expenditures, and research output, as measured by the quantity and visibility of scientific journal articles. The study is based on approximately 500 U.S. colleges and universities. For each of 11 fields of science, there is strong indication of a linear relationship between R&D expenditures and number of papers. The evidence also indicates a positive relationship between number of cites received per paper and number of papers published, but only for papers published in the basic research journals of the fields of chemistry, physics, and biology.  相似文献

In this paper, we discuss methodological issues that emerged as we worked through a small empirical research project, ‘Engaging Aboriginal students in education through community empowerment’. Recent national policy statements (see, for example, MCEETYA 2000, NBEET 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self-determination and improve educational outcomes. In keeping with these recommendations, our project aimed to challenge assimilationist frameworks and sought to ‘empower’ members of the local Aboriginal community through participation in the project.  相似文献

The evaluation of promisingness is central to knowledge building and knowledge creation but remains largely unexplored. As part of a design-based research program to support promisingness judgments, the present study implemented an intervention in a sixth grade science class, with the goal of exploring the potential of promisingness judgments to foster scientific understanding and epistemic beliefs. Aided by a Promising Ideas Tool and pedagogical supports designed for this intervention, students explored the concept of promisingness, judged the promisingness of their community ideas, and engaged in iterative cycles of idea refinement. Results indicated that students were capable of improving their understanding of promisingness and making promisingness judgments deemed sensible by domain experts. The conceptual understanding and epistemic beliefs displayed by students improved over the course of the intervention, and such improvement happened in tandem with students’ understanding of promisingness. The implications of this exploratory study and future research are discussed.  相似文献

1IntroductionIt is i mportant for the economic development of acountry to maintain the stabilization of exchange rate,so the intervention of exchange rate has become thetopic of the main concerns of the economic and math-ematical circles[1-5].To maintain the stabilization ofexchange rate,many countries use target zone re-gi mes,that is,the central banks intervene in the for-eign exchange market such that the exchange ratestays within the interval[a,b].There are fixed costand cost proportional …  相似文献

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6~84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P<0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P<0.01). (3) Soil iodine value was 0.11~2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution.  相似文献

There is a lack of systematic research on the training of clinicians toward providing counselling services and support to individuals with Fetal Alcohol Spectrum Disorder (FASD). The aim of this qualitative project was twofold: (1) to develop and pilot a clinical consultation process that would address clinicians’ reported need for greater communication and information sharing in serving clients affected by FASD; and (2) to build a model of FASD-informed clinical counselling practice by examining this consultation process and by capturing the experiences of clinicians who were involved. Findings from focus groups and meeting minutes are reported with respect to the model’s focus on reflection, communication, and action.  相似文献

This study examined perceptions of college of education students and their experiences with Channel One, a privately-owned news service used in public education. Given that about one-third of middle and high schoolers in the US view the broadcast every school day, the authors surveyed 172 freshmen to discern their views and attitudes toward Channel One programming and commercials and the role colleges and universities might play in relation to this media service. While most studies on Channel One have been conducted from a K-12 point of view, the goal of this study was to reconsider the topic from the perspective of prospective teachers and post-secondary education.

This study investigated the effects of a brief meditation intervention on perceived stress, mindfulness, and sleep quality for college freshmen who have aged out of foster care. Thirty-six youth who had aged out of foster care and enrolled at a large midwestern 4-year university (n?=?16 experimental group, n?=?20 control group) participated in a study in which they were assessed three times on the dependent variables. Students also participated in a focus group after the intervention ended. Four sessions of the brief mindfulness intervention resulted in significant short-term reductions in stress levels and increases in sleep quality. Finding effective personal interventions to increase chances for college success for students with histories in foster care can also offer potential insight toward the development of educational models and resources for other vulnerable college student populations.  相似文献
