Users increasingly use mobile devices to engage in social activity and commerce, enabling new forms of data collection by firms and marketers. User privacy expectations for these new forms of data collection remain unclear. A particularly difficult challenge is meeting expectations for contextual integrity, as user privacy expectations vary depending upon data type collected and context of use. This article illustrates how fine-grained, contextual privacy expectations can be measured. It presents findings from a factorial vignette survey that measured the impact of diverse real-world contexts (e.g., medical, navigation, music), data types, and data uses on user privacy expectations. Results demonstrate that individuals’ general privacy preferences are of limited significance for predicting their privacy judgments in specific scenarios. Instead, the results present a nuanced portrait of the relative importance of particular contextual factors and information uses, and demonstrate how those contextual factors can be found and measured. The results also suggest that current common activities of mobile application companies, such as harvesting and reusing location data, images, and contact lists, do not meet users’ privacy expectations. Understanding how user privacy expectations vary according to context, data types, and data uses highlights areas requiring stricter privacy protections by governments and industry.  相似文献

Spatial thinking predicts Science, Technology, Engineering, and Mathematics achievement, yet is often absent from educational policy. We provide benchmarks of teachers' usage and perceptions of spatial activities in practice in the reception classroom (first year of primary school). In this questionnaire study of educational professionals working in the reception classroom in England (N = 104), we found that spatial and numeracy activities were perceived as significantly less important, and were reportedly completed significantly less often, than literacy or life skills. Despite the lower perceived importance of spatial skills in curriculum guidance in England, rates of reported spatial activity use were encouragingly high and were broadly comparable to those of numeracy. Teachers had moderate anxiety levels for both spatial and mathematics domains. The findings highlight a need to elevate teachers' understanding of the importance of developing children's early spatial and numeracy skills, which may begin with efforts to reduce spatial and mathematics anxiety.  相似文献

There is a known association between LEGO® construction ability and mathematics achievement, yet the mechanisms which drive this association are largely unknown. This study investigated the spatial mechanisms underlying this association, and whether this differs for concrete versus digital construction. Between January 2020 and July 2021, children aged 7–9 years (N = 358, 189 female, ethnicity not recorded) completed spatial and mathematics tasks, and either a concrete or digital Lego construction task. Mediation analyses examining direct and indirect pathways (through spatial skills) between Lego construction ability and mathematics explained 8.4% to 26.6% of variance in mathematics scores. Exploratory moderated mediation analyses revealed that only the indirect path through mental rotation differed between Lego conditions. Findings are discussed in relation to theories of spatial-numerical associations and the potential of Lego training for mathematics improvement.  相似文献

The rapid and unprecedented shift from face-to-face instruction to remote online learning as a consequence of the COVID-19 pandemic had a substantial impact on teaching and learning in Higher Education: students had to adapt to a new way of learning, away from typical campus settings and their peers, and to new forms of assessments. This study examined academic stress, learning strategies, motivation and ways of coping from a sample of 177 unique students from a large London university, collecting primary data via survey at three time points during the academic year 2020/21 when teaching was remote and online only. Our findings show how patterns in academic stress, learning strategies, motivation and coping vary over the course of the academic year giving novel insight into how student learning and adaptation to the situation changed over time. We also report on differences in these patterns according to year group and for those students who are the first-in-family to attend university and those who are not. Based on these findings we identify priority areas where higher education institutions should support undergraduate students and provide evidence that some groups of students may need more and targeted support to secure their ongoing learning and well-being.  相似文献

This study situates children's early notions of average within an inquiry classroom to investigate the rich inferential reasoning that young children drew on to make sense of the questions: Is there a typical height for a student in year 3? If so, what is it? Based on their deliberations over several lessons, students' ideas about average and typicality evolved as meaning reasonable, contrary to atypical, most common (value or interval), middle, normative, and representative of the population. The case study reported here documents a new direction for the development of children's conceptions of average in a classroom designed to elicit their informal inferential reasoning about data.  相似文献

In educational research and policy circles, college and career readiness is generating great interest. States are adopting various policy initiatives, such as rigorous curricular requirements, to increase students’ preparedness for life after high school. Implicit in many of these initiatives is the idea that college readiness and career readiness are essentially the same thing. This assumption has persisted, largely untested. Our paper explores this assumption in greater depth. Using two national datasets and an instrumental variables approach to mitigate selection bias, we evaluated the effects of completing Algebra II in high school on subsequent college and career outcomes (i.e., persistence and graduation as well as wages and career advancement). Results suggest Algebra II matters more for college outcomes than career outcomes and more for students completing Algebra II in the early 1990s than in the mid-2000s. Study limitations are discussed along with directions for future research, such as evaluating the opportunity cost associated with taking Algebra II for students seeking careers upon high school completion.  相似文献

A cross-sectional survey of a convenience sample of 1,199 pharmacists was conducted to describe pharmacists'' use and perception of UpToDate®. Of 472 (39%) respondents, 217 (46%) reported using UpToDate. Most respondents who used or had heard of UpToDate indicated willingness to change a treatment plan based on UpToDate recommendations (77%). Many believed that UpToDate is updated weekly (31%) or monthly (49%) and that all articles undergo external peer review (51%). In conclusion, the majority of respondents reported that they would adjust drug therapy based on UpToDate recommendations; however, many pharmacists may hold misconceptions regarding the updating and peer-review processes.  相似文献

Engaging in relationships with other organizations is one way for nonprofit community sport organizations (CSOs) to acquire needed resources, knowledge, and other social benefits while achieving important public purposes and building community cohesion. This study explored the processes and outcomes of interorganizational relationships in CSOs through semi-structured interviews with presidents of these organizations (N = 20). The findings revealed key relationship processes including trust, consistency, balance, and engagement as well as specific management skills. The findings also revealed that relationships impacted CSOs through enabling improvements to program/service quality and operations, and enhancing community presence. The study contributes to the interorganizational relationship literature and our understanding of how relationships advance organizational goals in this small nonprofit context.  相似文献

Building on previous research in which we provided an opportunity for female college athletes to construct their own photographic portrayals, this study explored young female athletes' perceptions of the college athlete photographs. Fifty-two girls participated in focus group interviews where they viewed and discussed the images. The young athletes particularly liked images they perceived to show authentic athletes (e.g., in athletic settings, with appropriate sport attire), images they could relate to due to personal experiences, and images that reflected competent and passionate sportswomen. Images perceived as revealing a lack of motivation, poor sporting attitudes, and nonathletic poses generally were disliked. Images depicting multiple social identities (e.g., an athlete in a dress) were controversial and generated much discussion.  相似文献
