This exploratory study applies and extends a new model of media attendance to examine factors that determine current levels of sharing files through peer-to-peer networks among college students, and to predict downloaders' intentions to discontinue the behavior in the future. In a multiple regression analysis, downloading activity was found to be positively related to deficient self-regulation and the expected social outcomes of downloading behavior. Downloading activity was lessened by dissatisfaction with poor quality downloads. Those who are willing to discontinue downloading are motivated by fear of punishment, but skilled and habitual downloaders were unlikely to discontinue. Normative beliefs also affected downloading. The perception that downloading was morally unacceptable was positively related to intentions to discontinue downloading, while beliefs that the behavior was morally acceptable were positively related to current downloading activity.
Interventions in Canada to address obesity have largely been limited to individual-level change through education rather than a population-level public policy approach. Little is known about obesity policy support in Canada, and substantial national variation in obesity policy support prevents direct transferability of these policies among nations. Our study recruited 521 young adults for an online survey through leaflets and flyers. We investigated how respondents’ demographics, health characteristics, political attitudes, beliefs regarding causes of obesity, and national identity affected their support for obesity policy. Results showed that there is high support for many obesity policies among Canadian young adults. Including Canadian national identity in regression models was significant in explaining obesity policy support beyond the combined effect of other predictors. Further exploration of national identity, in Canada and elsewhere, has implications for understanding obesity policy support that might assist policy makers in making more informed decisions in addressing obesity
Background Existing patient-reported outcome (PRO) measures may not be relevant to the full range of functional and vision-related quality of life (VR-QOL) concerns of individuals with vision impairment due to severe peripheral field loss (PFL). Measurement of VR-QOL in severe PFL is important in order to determine the effectiveness of vision rehabilitation interventions for this population. The purpose of this study was to characterize the impact of severe PFL due to retinitis pigmentosa (RP) and glaucoma on VR-QOL as the initial phase in the development of a novel PRO measure. Methods Individuals with severe PFL due to RP or glaucoma were recruited from the Kellogg Eye Center and the Association for the Blind and Visually Impaired. Participants completed semi-structured qualitative interviews, the Impact of Vision Impairment (IVI) questionnaire and the RAND 36-Item Health Survey. Interviews were analyzed by two coders using thematic analysis. A matrix analysis was conducted to compare VR-QOL by cause of severe PFL. Sample size was determined by thematic saturation. Results The study included 37 participants (19 RP, 18 glaucoma). Median best-corrected visual acuity for those with RP and glaucoma was 20/40 and 20/27.5, while Pelli-Robson contrast sensitivity was 1.2 log contrast sensitivity (logCS) and 1.1 logCS, respectively. Median domain scores on the IVI (reading, mobility, well-being) ranged from a low of − 0.2 to a high of 0.7 logits in those with RP and from 0.5 to 1.2 logits in those with glaucoma. Qualitative interviews identified six VR-QOL themes relevant across participants with both RP and glaucoma, including activity limitations, driving, emotional well-being, reading, mobility, and social function. VR-QOL concerns were largely consistent among those with severe PFL due to RP and glaucoma. These overarching themes contained content relevant to specific challenges related to severe PFL. Conclusions There are commonly occurring VR-QOL concerns among individuals with severe PFL due to RP and glaucoma. The outlined themes will serve as the basis for development of the Low Vision Severely Constricted Peripheral Eyesight (LV-SCOPE) Questionnaire.
News organizations' online commenting tools have been touted as a boon for the deliberative process, yet only to the extent that they are used by a diverse group of participants who are civil and who provide information that enriches dialogue. The researchers in this study analyzed the degree to which posts in newspaper forums originated from frequent contributors and the civil and informational characteristics of those contributions. A content analysis of comments (N = 2,237) within forums adjacent to opinion articles on websites of 15 U.S. newspaper dailies was conducted to assess their civility (uncivil character attacks and uncivil language) and informational attributes. Frequent contributors-people who post often on a forum in a short period-were less likely to be civil and informational.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
