Consumption of single-use bottled water has created severe environmental pollution problems around the world. By incorporating the theory of planned behavior with the additional cognitive and behavioral factors of perception, prior behavior, and knowledge variables, this study examined college students’ bottled water consumption intentions. Results show that perceived peer norm, behavioral control, and perceived bottled water benefits are significantly related to purchase intentions, as are prior levels of bottled water and tap water consumption. The same is not true for attitude toward and knowledge of bottled water consumption. Perceived tap water benefits negatively moderated the attitude-purchase intention relationship, whereas prior bottled water consumption negatively moderated the behavioral control-purchase intention link. 相似文献

Digital healthcare is in the spotlight due to the prevailing COVID-19 situation. To get the deeper understanding of the healthcare consumers' adoption of e-government telemedicine service (EGTMS), the present research extends the unified model of e-government adoption (UMEGA) with perceived severity, self-efficacy, and political trust. The extended UMEGA model is empirically validated with 452 valid Indian healthcare consumers' responses. The findings reported that performance expectancy, perceived severity, effort expectancy, and perceived risk significantly influenced Indian healthcare consumers' attitudes towards EGTMS. Further political trust showed significant influence over social influence. However, social influence is observed as non-significant. Furthermore, attitude, political trust and facilitating conditions significantly influenced individuals' behavioral intentions towards EGTMS and observed significant influence of self-efficacy on effort expectancy. This is the first study that reveals the critical factors of Indian healthcare consumers' behavioral intention towards EGTMS. With the upsurge in e-government healthcare services, the outcomes of the study will benefit stakeholders such as governmental agencies, marketers, public administrators, and healthcare professionals as they provide suitable strategic recommendations to design and implement e-government telemedicine services. 相似文献

AbstractThe theory of planned behavior has received significant attention more recently. This study used a survey to apply the theory of planned behavior to predict the Internet utilization behavior among 214 undergraduate agricultural students in Iran. Coefficient correlations and linear regressions were employed to analyze relationships among constructs. Results revealed that subjective norm and intention were the strongest predictors of the Internet utilization behavior, which explained 57% of the variance. Perceived behavioral control was the most significant predictor of the Internet use intentions. Subjective norms, to a lesser degree also had important influences on intention. Attitude did not surface as an effective direct predictor of the Internet utilization behavior. Finally, the theory of planned behavior was supported as an effective model explaining the Internet utilization behavior. The most prevalent reason to stop using the Internet was that they were experiencing problems getting access to the Internet. 相似文献

According to the Nielsen Music 360 Research Report, 67% of all music consumers in the United States used digital music streaming services to listen, discover, and share music online in 2014 (The Nielsen Company, 2014). As such, communications scholars and music industry professionals are beginning to recognize the importance of understanding the factors that influence digital music listener behavior. Therefore, this study proposes an expanded theory of planned behavior model (TPB) by incorporating social identification into the original TPB model framework in an effort to gain a better understanding of people’s intentions to use digital music streaming services as well as the amount of time spent listening to them.
Results suggest that both the original TPB and expanded TPB models can be successfully applied within the context of digital music streaming service use. Specifically, attitudes emerged as positive contributors to intention to use digital music streaming services, while social identification and behavioral intention emerged as positive contributors to streaming behavior. Both models also explained a larger percentage of intention to use digital music streaming services as compared to streaming behavior operationalized as total time spent listening. Thus, this study implies the practical importance of understanding the differences between what drives listener intentions as compared to what drives the actual amount of time listeners spend using digital music streaming services. 相似文献

TV reporters in Taiwan often encounter accidents during regular assignment runs, which may be a significant factor that increases their intentions to leave their job. Occupational hazard has always been ignored by news media organizations. Recent research has shown that a positive organizational safety climate may improve safety-related issues. To build on previous research conducted, this study investigates the moderating effect of safety climate between safety leadership and turnover intentions. This research collected 268 valid samples with an 89% response rate. Using the hierarchical linear model, results show that the transformational leadership style is negatively related to turnover intentions and the passive leadership style is positively related. Moreover, the moderation tests found a negative relationship between the interaction of passive leadership and safety and employees' turnover intentions. This implies that when reporters are working in a positive safety climate environment, their turnover intentions will be significantly lower. On the contrary, the positive moderating effect of safety climate on the relationship between transformational leadership and turnover intention is not significant. 相似文献

This study investigates the interrelationships between technological predictors and behavioral mediators in explaining users' continuance intention for online tax filing. Building on information systems (IS) success and IS continuance literature, this study proposes an extended conceptual framework by adding perceived functional benefit (PFB) as mediating, perceived risk as moderating, and demographic characteristics as control variables. The data collected, through a web-based survey, from 409 users of e-tax services in an emerging economy are analyzed through covariance-based structural equation modeling. Results confirm that PFB, confirmation of expectation, and satisfaction are the major antecedents of continuance intention for e-tax filing. The study also finds the evidence for the indirect effects of IS success factors on continuance intention through such antecedents. In addition, results suggest that the relationships between PFB and satisfaction as well as between PFB and continuance intention are contingent on the users' levels of perceived risk. The study concludes with the useful implications for academicians and policymakers in the context of an emerging economy. 相似文献

This study presents the IDEA (internalization, distribution, explanation, action) model as an easy-to-use and situationally generalizable framework for quickly developing effective messages instructing people on how to protect themselves before and during high-risk events, crises, disasters, and other emergencies. The model consists of four elements: helping message recipients internalize the potential impact of the risk or crisis event, identifying appropriate channels and strategies for distributing the risk or crisis event messages, offering a brief and intelligible explanation of the nature of the risk or crisis, and providing specific self-protective action steps for people to take. The model may be used to design messages in any risk, crisis, or emergency context. Through a posttest-only quasi-experimental cross-sectional research experiment, this study measured the perceived message effectiveness, cognitive understanding, and behavioral intentions of those viewing a television news story about a crisis situation employing the IDEA model compared to those viewing a similar story replicating typical crisis event news stories delivered to general publics. This comparative examination revealed that the message designed according to the IDEA model was significantly more effective than the status quo message and resulted in greater behavioral intentions to engage in appropriate self-protective actions in the event of an acute risk or crisis situation. Strategies for implementing the model are also provided. 相似文献

Using logic suggested by the model of intuitive morality and exemplars, we examined the impact of exposure to terrorist attack news coverage on the salience of moral intuitions and prosocial behavioral intentions toward outgroup members. In an experiment, participants were randomly assigned to watch news of the 2015 Paris terrorist attacks or a control news story. Afterward, we measured the salience of five moral intuitions (sensitivity to care, fairness, loyalty, authority, and purity) and the participants’ prejudice (i.e., the lack of intentions to help outgroup members). Results showed that exposure to terrorist attack news (a) increased the salience of respect for authority and subsequently (b) reduced prosocial behavioral intentions toward outgroup members. Closer inspection revealed that authority salience mediated the effect of terrorist news exposure on these behavioral intentions toward outgroup members. In a second study using the same design as in the first study, we ensured that the ingroup and the outgroup addressed in the first study were indeed perceived differently on dimensions of ingroup membership. 相似文献

This study investigates the docudrama hypothesis—the idea that fiction based on real stories can influence audience members’ perception of political reality—in the context of current debates on partisan selective exposure and reinforcement effects. It does so by analyzing the influence of an Oscar-nominated docudrama on viewers’ attitudes and behavioral intention using propensity score matching. By means of a representative survey, we find strong evidence of partisan selective exposure and avoidance. Furthermore, among respondents with a similar likelihood of film attendance, actual attendance has a strong association with positive retrospective evaluations of the political coalition glorified in the movie, and an indirect relationship—via retrospective evaluations—with voting intentions. Discussion of the findings shed light into potential real-world political effects of partisan selective exposure using content other than news. 相似文献

This study sought to better understand what factors best predict consumers’ intention to cut the cord on cable television and adopt video streaming as their primary source of television. Utilizing media substitution theory as the conceptual framework, this study conducted a nationwide survey (N = 200). Findings show that perceived advantages of streaming applications over traditional television best predicted intentions to cut the cord on cable and adopt Web streaming; these perceptions mediated the relation between user frustrations with using older television technology and intentions to cut the cord. Entertainment needs were not significant predictors of cord-cutting intentions. 相似文献

The study tested the Theory of Reasoned Action in Korea. Questionnaires measuring behavioral intention to study for final exams were distributed to 144 Korean college students. The findings indicated that attitude toward behavior and subjective norm predicted behavioral intention. When attitude toward behavior was divided into social and personal attitudes toward behavior based on the types of outcomes that behavior brings about, it was only social attitude toward behavior had a significant weight in predicting behavioral intention among the Korean students. Positive correlations were observed between the strength of interdependent self‐construal and the normative component and between the strength of independent self‐construal and the attitudinal component. Self‐construals, however, did not influence the relative weights of the two components in predicting behavioral intention. 相似文献

Online library resources can act as a trusted source to find various references for conducting research or writing research papers. With the increasing number of published papers, the use of online library resources becomes increasingly important for academics, including for university students. This study aims to investigate the factors that lead to the continued use of online library resources among university students in developing countries, especially Indonesia. We investigate the impact of resource quality, confirmation, satisfaction, perceived usefulness, perceived ease of use, and perceived enjoyment of users on their intention to continue using online library resources and the effect on e-WOM intention. This study will enhance the Post-Acceptance Model of Information System (IS) Continuance by adding several other constructs and tested using data from 215 university students in Indonesia who have used online library resources. The method used to analyze the data is Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results of the study indicate that satisfaction and perceived enjoyment have a significant effect on the intention to continue using online library resources. In addition, it was also found that the continuation intention to use online library resources also affects the user's intention to convey it to others (e-WOM intention). This study provides insight to online library resources service providers in making improvements and formulating strategies to increase users' intentions to continue using their online library resources. 相似文献

Subjects differing in interpersonal construct differentiation completed both an attitude measure and a behavioral intentions measure (in which subjects’ behavioral intentions in each of nine attitude‐relevant interpersonal situations were assessed) toward a subject‐selected target person. While the overall correlation between attitude and the behavioral intentions index was high (r = .85,), low‐differentiation subjects displayed significantly greater attitude‐behavioral intentions consistency (r = .95,) than did high‐differentiation subjects (r = .75). Correspondingly low differentiation subjects exhibited significantly less variability in the evaluative direction of their behavioral intentions than did high‐differentiation subjects (construct differentiation and variance in individuals’ behavioral intentions were correlated, r = .37). The results are interpreted as suggesting that within a given domain, persons with developmentally less advanced cognitive systems place greater reliance on evaluative consistency principles in organizing their beliefs and behaviors and hence are more likely to exhibit attitude‐behavior consistency than are persons with more developed systems. 相似文献

The purpose of this study was to investigate factors that influence professors’ and students’ intentions to add each other as friends on Facebook. Participants were 160 professors and 249 students from different universities in the United States. Consistent with theory of reasoned action, intention was the strongest predictor of them adding each other as Facebook friends. However, among faculty members, a personal attitude was the most significant predictor of the intention to add students as friends. For students, subjective norm was the most significant predictor of the intention to friend professors. 相似文献
