Adapted from Chang et al.'s (2006) models, this study examines factors that influence adoption and non-adoption of social network sites (SNS) in adopters (Continuers, Discontinuers) and non-adopters (Potentials, Resistors). Chi-square and t-test were used to analyze the survey data of Singapore's working adults and Internet users (N =222). The findings reveal innovation characteristics (relative advantage, compatibility, complexity) and perceived popularity differ significantly in three pairs of adopter categories. Results show Continuers and Potentials are concerned more about image than Discontinuers and Resistors, while technology cluster differs between adopter vs. non-adopter and Continuers vs. Discontinuers. Moreover, the study suggests younger people tend to adopt SNSs, females continue to use SNSs more, and potential SNS users are more innovative. Lastly, a regression model to forecast the adoption of SNSs is proposed in which age, compatibility, technology cluster, and perceived popularity are predictors.  相似文献

Over the last 20 years, humanities and archival scholars have theorized the ways in which archives imbue records with meaning. However, archival scholars have not sufficiently examined how users understand the meaning of the records they find. Building on the premise that how users come to make meaning from records is greatly in need of examination, this paper reports on a pilot study of four book history students and their processes of archival meaning-making. We focus in particular on behaviors of an interpretive rather than forensic nature. This article includes a discussion of the theoretical concepts and scholarly literature that shaped our goals for this paper. It then discusses the methodology and our interpretations of the research findings, before turning to a discussion of the findings’ implications and directions for future work.  相似文献

ABSTRACT

The idea that pornography promotes sexism is a commonly purported one. This study employed an online sample of heterosexual men (N = 323) to investigate the relationship between pornography use (in terms of both overall level of pornography use and use of violent and/or humiliating pornography) and old-fashioned and modern sexism. The moderating effects of agreeableness and perceived realism of pornography were also assessed. Level of general pornography use and use of violent and/or humiliating pornography was not predictive of either sexism measure. Agreeableness was negatively predictive of both sexism measures, whereas perceived realism was positively predictive of sexism. Agreeableness and perceived realism did not moderate the relationship between level of pornography use and any of the outcome measures.  相似文献

This paper uses Tronto's political ethics of care as a normative framework to evaluate a model of teaching and learning professional development. This framework identifies five integrated moral elements of care – attentiveness, responsibility, competence, responsiveness and trust. This paper explicates on each of these elements to evaluate the piloting and implementation of a teaching and learning professional development model at a South African higher education institution. The political ethics of care was found to be a useful normative framework for a group of higher educators to reflect on the process of engaging in teaching and learning professional development in that it revealed the importance of differential power relations, the importance of working collaboratively and being attentive to the needs of both caregivers and care receivers.  相似文献

Contract cheating occurs when students outsource assessed work. In this study, we asked experienced markers from four disciplines to detect contract cheating in a set of 20 discipline-specific assignments. We then conducted a training workshop to improve their detection accuracy, and afterwards asked them to detect contract cheating in 20 new assignments. We analysed the data in terms of sensitivity (the rate at which markers spotted contract cheating) and specificity (the rate at which markers spotted real student work). Pre-workshop marker sensitivity was 58% and specificity was 83%. Post-workshop marker sensitivity was 82% and specificity was 87%. The increase in sensitivity was statistically significant, but the increase in specificity was not. These results indicate that markers can often detect contract cheating when asked to do so, and that training may be helpful in improving their accuracy. We suggest that markers’ suspicions may be crucial in addressing contract cheating.  相似文献

Most new students experience school to university transition as challenging. Students from backgrounds with little or no experience of higher education are most vulnerable in this transition, and most at risk of academic failure. Emotion appears implicated in the differential way in which first-generation students and students with family familiarity of university experience the transition. This article draws on the voices of first-year dental and oral hygiene students at a South African dental faculty regarding university transition experiences. It draws on the construct of capital and Archer's [(2002). Realism and the problem of agency. Journal of Critical Realism Alethia, 5(1), 11–20] understanding of ‘competing concerns’ to examine how emotion shapes students' experiences of university transition and how they position themselves with regard to these experiences. The article explicates the ways in which emotional commentary and classed locations intersect, exploring the extent to which this intersection shapes young people's framing of their concerns of ‘being a student’ and ‘becoming a dentist’. The article identifies aspects of the university's material and cultural environments which shape students' emotional responses and which consequently are implicated in the perpetuation of class-based differential life chances.  相似文献

In one study, parameters were estimated for constructed-response (CR) items in 8 tests from 4 operational testing programs using the l-parameter and 2- parameter partial credit (IPPC and 2PPC) models. Where multiple-choice (MC) items were present, these models were combined with the 1-parameter and 3-parameter logistic (IPL and 3PL) models, respectively. We found that item fit was better when the 2PPC model was used alone or with the 3PL model. Also, the slopes of the CR and MC items were found to differ substantially. In a second study, item parameter estimates produced using the IPL-IPPC and 3PL-2PPC model combinations were evaluated for fit to simulated data generated using true parameters known to fit one model combination or ttle other. The results suggested that the more flexible 3PL-2PPC model combination would produce better item fit than the IPL-1PPC combination.  相似文献
