The importance of innovation in healthcare has increased within the last decades as challenges, like rising costs and an aging demographic, have to be solved. The degree of innovativeness in healthcare is strongly influenced by the National Health Innovation System, which as a sectoral innovation system encompasses a wide variety of actors and related knowledge. Despite the highly practical relevance of the topic, there are only a few studies that analyze innovation in healthcare on a national level. Thus, this study is a starting point and, building on the theoretical framework of national innovation systems, answers the following questions: “Can countries be grouped by their innovation output in healthcare and do those groups differ in factors describing the healthcare system? Do countries with strong national innovation systems also have strong national health innovation systems and vice versa?” We compare the healthcare innovation output of 30 OECD countries using a multi-indicator approach and categorize them into four distinct groups using cluster analysis. The cluster consisting of the Scandinavian countries, the Netherlands and Switzerland shows the highest innovation output measured in knowledge production and knowledge commercialization. Surprisingly, these countries, with the exception of Switzerland, only rank in the medium group when considering the entire national innovation system. Policymakers and researchers might be particularly interested in studying the healthcare systems of these countries.  相似文献

There is a strong relationship between experiencing violence and participating in behaviors that increase the risk of contracting sexually transmitted infections. Sexual health education (SHE) tailored to the unique needs of female survivors of violence is needed. This paper presents findings from 40 surveys and 33 accompanying interviews with stakeholders representing 31 agencies in the violence advocacy community in Arkansas to investigate the feasibility, acceptability, and perceived need of a SHE program for female survivors of violence. Data also explore the role and preferences of community agencies in the design and implementation of such a program. Interviews with stakeholders revealed three themes: intervention concerns, content, and structure.  相似文献

Despite the many implicit references to the social contexts of search within information seeking and retrieval research, there has been relatively little work that has specifically investigated the additional requirements for collaborative information-seeking interfaces. Here, we re-assess an existing analytical inspection framework, designed for individual information seeking, and then apply it to evaluate a recent collaborative information-seeking interface: SearchTogether. The framework was built upon two models of solitary information seeking, and so as part of the re-assessment we first re-frame the models for collaborative contexts. We re-frame a model of search tactics, providing revised definitions that consider known collaborators. We then re-frame a model of searcher profiles to analyse support for different group dynamics. After presenting an analysis of SearchTogether, we reflect on its accuracy, showing that the framework identified eight known truths, eight new insights, and no known-to-be-untrue insights into the design. We conclude that the framework: (a) can still be applied to collaborative information-seeking interfaces; (b) can successfully produce additional requirements for collaborative information-seeking interfaces; and (c) can successfully model different dynamics of collaborating searchers.  相似文献

Declining enrolments in science, technology, engineering and mathematics (STEM) disciplines and a lack of interest in STEM careers are concerning at a time when society is becoming more reliant on complex technologies. We examine student aspirations for STEM careers by drawing on surveys conducted annually from 2012 to 2015. School students in years 3 to 12 (n?=?6492) were asked to indicate their occupational choices. A logistic regression analysis showed that being in the older cohorts, possessing high cultural capital, being male, having a parent in a STEM occupation and high prior achievement in reading and numeracy, were significant. This analysis provides a strong empirical basis for school-based initiatives to improve STEM participation. In particular, strategies should target the following: the persistent lack of interest by females in some careers, improving student academic achievement in both literacy and numeracy and expanding knowledge of STEM careers, especially for students without familial STEM connections.  相似文献

Abstract

This study focuses on the parental involvement among Eastern European immigrant parents of elementary school students in Canada. Interviewed parents (N?+?19) were educated in several Eastern European countries and had children attending elementary schools in the province of Ontario at the time of the study. The analysis was informed by the concepts of social and cultural capital developed by Pierre Bourdieu. It was found that Eastern European immigrant parents see their role supporting children mainly in the home by emphasizing academic achievement and extracurricular activities. Despite high levels of cultural capital there was a variation in the amount of social capital available to immigrant parents. Those who managed to recreate rich social networks in the new country communicated with teachers more successfully and were satisfied with school.  相似文献

Background: The development of context-based science curricula has been identified as one of the most effective curricular innovations to develop interest and better conceptual understanding of many areas in science. However, such a curriculum can be more fruitful if it starts with the assessment of learners’ contextualized knowledge about the science topic in hand.

Purpose: The focus of this paper is to investigate secondary school learners’ knowledge of the optical phenomena of reflection and refraction in relation to certain contexts.

Sample: The sample for the study consisted of two Grade-11 intact groups of 70 learners in total at a selected senior secondary school in the Mthatha District of the Eastern Cape Province in South Africa.

Design and methods: The study focused on exploring the learners’ conceptions about the optical phenomena of reflection and refraction. The data were collected from three two-tier questions, which exposed the learners to certain contexts which could be explained using optics principles. The first tier of each question was a context-based multiple-choice question and in the second tier, the participants were asked to justify their answers to the first tier.

Results: Majority of the participants failed to correctly interpret the given contexts using optics principles. Moreover, only a few learners could justify their scientifically acceptable answers with scientifically acceptable explanations.

Conclusions: The participants experienced serious conceptual difficulties when they were required to apply the optics concepts in the real-world contexts presented to them. Moreover, the participants’ conceptual difficulties about reflection and refraction were also found to be associated with their inability to understand correctly the optical processes involved in vision.  相似文献
