The present study examined the factors associated with individuals' use of three different text-based communication media: e-mail, cell-phone texting, and Facebook Wall postings. Three theoretical perspectives, including media richness theory, uses and gratifications, and perceived network effects, were examined. Using data from a survey of college students (N=280), the study found that the theoretical constructs from these theories play different roles when applied to different technologies. The results suggest that a simultaneous consideration of technological attributes, users' motivations, and social circumstances in which users select and use the technology is useful for fully understanding the dynamics of the selection and the use of a given technology.  相似文献

Abstract This study aims to propose an integrated model of smartphone adoption that incorporates social influences (SIs), perceived technicality, as well as hedonic and utilitarian attitudes into the technology acceptance model. The proposed model was empirically evaluated by using survey data collected from 239 Korean college students to investigate their perception and attitudes toward smartphone adoption intention. Our results show that users' attitudes and their adoption intention are highly influenced by SI and positive self-image. This implies that a smartphone is a symbolic product that can signal affiliation and enhance the users' status in a group. The results also indicate that hedonic enjoyment is equally important as utilitarian usefulness in predicting the adoption intention, and the two variables mediate the relationships between SI, positive self-image, perceived technicality, and the intention to use. Consequently, the results reveal that smartphones are convergent media that can be viewed as both task-oriented and entertainment-oriented devices.  相似文献

This study analyzed the survey data from 566 Korean children between the ages of 10 and 15 to examine the role of Internet literacy and parental mediation in solving the dilemma of children's Internet use. According to the findings, children's online participation was associated with increased exposure to online risks. The association was moderated by Internet skills and parental restrictive mediation; that is, for children with a high level of Internet skills and for children who received more restrictive mediation, the positive association between online participation and online risks weakened, but was still significant. The limited roles of Internet skills and parental restrictive mediation in children's Internet use were discussed in the context of media education.  相似文献

This study investigated the relationship between psychological resilience and its relevant variables by using a meta‐analytic method. The results indicated that the largest effect on resilience was found to stem from the protective factors, a medium effect from risk factors, and the smallest effect from demographic factors.  相似文献

Australia is at the forefront of tobacco control, yet 17% of Australian women smoke during pregnancy. Negative attitudes to smoking are intensified when the smoker is pregnant, consistent with a discourse that encourages surveillance of pregnant women. Such overt anti-smoking attitudes create a context which may make it difficult for pregnant smokers to seek assistance to stop. However, there is little evidence on the extent to which pregnant smokers are stigmatised by community members. We used vignettes to examine the degree of smoking-related stigma expressed by 595 Australian university students who rated a woman, described as a mother who was smoking or not, and pregnant or not. Further, we examined whether provision of individuating information reduced the degree of stigma. Mothers described as smokers were rated more negatively than those not, particularly if they were pregnant: smokers were perceived as unhealthy, and also as bad mothers. Provision of individuating information slightly reduced these effects. These findings support the view that smokers – particularly if pregnant – are subject to negative moral judgement. Our findings contribute to the ethical debate about stigma-inducing tobacco control efforts, and suggest that anti-smoking campaigns that contextualise smoking in pregnancy might reduce stigma and assist cessation.  相似文献

Abstract

The aim of this study was to attempt to replicate a study in adults: to determine whether pre-treatment enquiries about anxiety and pain in children, attending the dentist, influenced their subsequent reports of pain and anxiety immediately after treatment. One hundred and ninety five children aged from seven to 16, attending four Community Dental Clinics, were allocated at random to five groups. Before treatment the first group was asked questions about their dental anxiety, expectations and memories of pain. The second group was asked about dental anxiety and expectations of pain. The third group was asked only about dental anxiety; the fourth was asked only about pain. The fifth, the control group, was asked about none of these topics. All the children were asked after treatment to rate 1) their anxiety about dentistry and 2) their experience of pain in the treatment just completed. The children experienced less pain than they had expected. There were no differences between the groups in disruptiveness or in the amount of pain experienced. However, the children who were asked about both pain and dental anxiety (groups one and two) reported significantly less dental anxiety than the control group. These results are consistent with the conclusion that pre-treatment enquiries about both anxiety and pain have no effect on disruptiveness or the experience of pain but do reduce anxiety about dentistry.  相似文献

A number of models of behaviour have been applied to contraception use including subjective expected utility theory and social cognition models. Whilst correlates of contraception use have been identified, the limitations of these models include their failure to consider either contextual factors or changes in contraception use over time. Researchers have called for integrated and dynamic models of contraception use, which can be related to the changing contraception use of individual women and can also be readily operationalised to explore within and between subject differences in contraception use. The present study therefore used a qualitative methodology to explore women's contraceptive histories and to enable women to define the issues from their perspectives, resulting in a model of contraception use that is firmly located within the context of their own lives and allows an investigation of the factors and processes involved in changes in contraception use/non-use over time. This model conceptualises the predictors of contraception use in terms of the meaning and importance of a range of social goals, perceptions of vulnerability and constraints on or facilitators of contraception. Further the dynamic nature of these factors is described and it is illustrated how these core components vary over time according to situation, experience, and new information. The paper outlines the relevance of the findings for different models of decision-making processes and highlights the way that the model addresses the limitations of previous approaches.  相似文献

We developed a method for estimating the dollar utility of changes in job performance associated with illnesses and their treatments. Then we applied this method to predict, for each job in the economy, the difference in productivity costs associated with the illness of Seasonal Allergic Rhinitis (SAR) and that due to the difference between 2 commonly used treatments of SAR. The findings suggest that workers are 5% less productive when affected by SAR, and that when workers treat their SAR with desloratadine (a nonsedating antihistamine) instead of diphenhydramine (an over-the-counter 1st-generation antihistamine), they are 7% more productive, translating to a daily productivity cost differential between the 2 treatments of $11 per day, or $2.6 billion annually. The jobs most affected require high amounts of selective attention and perceptual speed (e.g., Aircraft Pilots and Flight Engineers, and those in the fields of manufacturing, security, and emergency response).  相似文献

Antecedents to trust (propensity to trust, perceived trustworthiness) and trust behaviors were examined in relation to team performance in a complex eight-mission military peacekeeping simulation. Teams were colocated or distributed and stayed in the same or transferred to a different context at task transfer. In Experiment 1, an ability and competence factor accounted for most of the variance in perceived trustworthiness and greater perceptions of teammates' abilities/competences predicted posttransfer performance. One's perception of how others perceived one's ability/competence increased over missions. In Experiment 2, propensity to trust did not predict performance; however, trust in others' and one's own ability/competence and trust behaviors predicted performance. At task and/or context transfer, teams produced more monitoring and less cooperating language in their communication.  相似文献
