Abstract

This article draws upon two conceptual frameworks—institutional culture in education and innovation studies—to contextualize findings from a digital intervention for underrepresented students applying to college. The qualitative data that inform this study's findings include 88 open-response surveys with school teachers, as well as campus observations from 52 participating high schools in the U.S. state of California. Through such a conceptual framework, this article highlights four institutional barriers that can inhibit widespread adoption of a promising innovation: (a) the challenge of tapping into participants’ intrinsic motivation; (b) forging opportunities for collaboration and communication between different stakeholders; (c) finding adequate time to schedule and implement an innovation; and (d) a dearth of support for digital resources.  相似文献

Fears exist that social media use by news media and journalists may affect basic journalistic tenets such as objectivity, gatekeeping, and transparency. As a result, more and more news media organizations are issuing guidelines to manage employee use of social media. In this article we discuss the complex relationship of a selection of market-leading news media organizations with prescribed use of social media. Applying content analysis to 12 existing social media guidelines, we elaborate on the various types of rules linked with the basic principles of journalism. A key intention of this research is to provide insights for media management and journalism scholars to better understand the use of social media by journalists and the implementation of guidelines by media organizations. More practically, this article can aid media organizations who are shaping their own set of rules regarding use of social media by their staff.  相似文献

This study aimed at (a) constructing a reliable and valid test to assess Ecuadorian 4–5-year olds’ number and arithmetic skills; (b) providing empirical data on Ecuadorian 4–5-year olds’ number and arithmetic skills; and (c) confronting these children’s actual performances with the performances expected by national experts in this domain. We administered the Test of Early Number and Arithmetic (TENA), developed on the basis of the Ecuadorian mathematics standards to 86 Preschoolers and 127 Kindergartners and asked 10 experts to evaluate TENA’s validity and predict children’s performances on it. Results supported the overall reliability and validity of the TENA. Furthermore, we observed differences in number and arithmetic competencies between and within Preschoolers and Kindergartners, but not between boys and girls. Finally, experts overestimated children’s performances on the test. The scientific and practical implications of these results are discussed.  相似文献

In Finland, the financial status of a family does not in general place any restrictions on a person's studies. However, in spite of equality of opportunity, class as a cultural and social issue is a significant factor guiding the education of young people. In the article, I analyse women with a working-class background studying at university, starting with experiences of class as it is lived. The data for the study have been generated using the memory work method. The analysis shows how class is manifested in the women's experiences as a sense of themselves as outsiders, being alone or ‘on their own’ and as feelings of inadequacy. The women are forced to find ways of doing things that suit them and to construct a space in which they can feel safe.  相似文献

Over the past decade Identity Management has become a central theme in information technology, policy, and administration in the public and private sectors. In these contexts the term ‘Identity Management’ is used primarily to refer to ways and methods of dealing with registration and authorization issues regarding persons in organizational and service-oriented domains. Especially due to the growing range of choices and options for, and the enhanced autonomy and rights of, employees, citizens, and customers, there is a growing demand for systems that enable the regulation of rights, duties, responsibilities, entitlements and access of innumerable people simultaneously. ‘Identity Management’ or ‘Identity Management Systems’ have become important headings under which such systems are designed and implemented. But there is another meaning of the term ‘identity management’, which is clearly related and which has gained currency. This second construal refers to the need to manage our moral identities and our identity related information. This paper explores the relation between the management of our (moral) identities and ‘Identity Management’ as conceptualized in IT discourse.  相似文献

The primary role of the shoulder joint in tennis forehand drive is at the expense of the loadings undergone by this joint. Nevertheless, few studies investigated glenohumeral (GH) contact forces during forehand drives. The aim of this study was to investigate GH compressive and shearing forces during the flat and topspin forehand drives in advanced tennis players. 3D kinematics of flat and topspin forehand drives of 11 advanced tennis players were recorded. The Delft Shoulder and Elbow musculoskeletal model was implemented to assess the magnitude and orientation of GH contact forces during the forehand drives. The results showed no differences in magnitude and orientation of GH contact forces between the flat and topspin forehand drives. The estimated maximal GH contact force during the forward swing phase was 3573 ± 1383 N, which was on average 1.25 times greater than during the follow-through phase, and 5.8 times greater than during the backswing phase. Regardless the phase of the forehand drive, GH contact forces pointed towards the anterior-superior part of the glenoid therefore standing for shearing forces. Knowledge of GH contact forces during real sport tasks performed at high velocity may improve the understanding of various sport-specific adaptations and causative factors for shoulder problems.  相似文献

In the present study, we tested the consequences of attention towards goalkeepers in association football penalty shootouts that have exclusively been derived from laboratory experiments. We conducted a retrospective analysis of all penalty shootouts during FIFA World Cups (1986–2010) and UEFA European Football Championships (1984–2012). We linked key variables of previous laboratory research to observable behaviour in the field that was coded by two independent coders. The following hypotheses were tested: first, attention towards goalkeepers results in more saves/better goalkeeper performance; second, goalkeepers can deliberately distract penalty takers by drawing attention towards themselves which results in less accurate penalty kicks/better goalkeeper performance. Results were in line with previous laboratory analyses as they showed that attention towards goalkeepers resulted in more saves/better goalkeeping performance. Further, if goalkeepers distracted penalty takers this also resulted in better goalkeeping performance. The applied implications of these findings are discussed for both goalkeepers and penalty takers in association football.  相似文献
