The primary purpose of the study was to identify relationships among sources of interpersonal influence, putative psychological mediators, and physical activity. The moderation of these relationships by age, body composition, and educational attainment was also evaluated. Responses from 1224 employees were collected through an online survey at a major healthcare facility in central Texas. Structural equation modeling was used to construct the Social Context Scale of Interpersonal Influence and to estimate its ability to explain intention to be physically active and predict physical activity behavior. Invariance testing provided estimates of moderation by age, education, and body composition. Home social context was positively associated with self-efficacy and positive anticipated outcomes and negatively associated with negative anticipated outcomes. Friend social context was positively associated with self-efficacy, positive anticipated outcomes, and intention. Teasing was positively associated with negative anticipated outcomes. Self-efficacy and positive anticipated outcomes were positively associated with intention. Negative anticipated outcomes were negatively associated with intention. The relationship between friend social context and both positive anticipated outcomes and intention was stronger for obese than non-obese respondents. Home social context was more strongly associated with self-efficacy for those with four year degrees than for those without. Self-efficacy was more strongly associated with intention for those with four year degrees than for those without. Self-efficacy predicted subsequent total leisure time physical activity and the relationship was stronger for respondents over 45 years of age than for those younger than 45. The association between self-efficacy and subsequent total leisure time physical activity was also stronger for respondents with a four year degree than for those without. Home and friend social contexts provide potential conduits for post intervention influence on physical activity behavior. The discussion of the benefits of physical activity among friends may encourage overweight and obese individuals considering exercise, especially those with limited physical activity experiences of their own. / text

<p>Syftet med föreliggande studie var att undersöka sambandet mellan elevers attityder, subjektiv norm, upplevd kontroll, intentioner, rättfärdiganden, motivation samt självvärdering i relation till benägenhet att fuska eller att avstå från att fuska. <em>The theory of planned behavior </em>(Ajzen, 2006) har använts som teoretisk modell för en enkätundersökning med 122 elever i grundskolans årskurs 9 och i gymnasieskolans årskurser 2–3. Resultatet av studien visar att intentionen att utföra ett beteende, som i denna studie är fusk, är den viktigaste prediktorn för beteendet i fråga. I föreliggande studie har även kunnat styrkas att rättfärdigande av eget fusk har en avgörande roll vad gäller beteende och intention. De övriga variablerna har en viss betydelse med inte i lika hög grad som intention och rättfärdigande.  Resultatet av studien har diskuterats utifrån intentionen och rättfärdigandets starka samband med beteendet.</p>

Traditional communications media has been transformed and reshaped with the introduction of the Internet and its technologies. The Internet has massively evolved over time, and the World Wide Web or otherwise referred to as Web 1.0 has developed to what is so called Web 2.0. The explosive diffusion of this global system has fostered the emergence of Web-based communities supported by the existence of globally connected individuals. As both the number of World Wide Web virtual community sites and users has expanded and grown quickly, these communities have become a subject of study to researchers of multiple disciplines. However, sustaining a successful operation of any Web 2.0 community depends on the continuous participation of its own users. It is massively important to maintain committed members in terms of continuous participation. Yet, their level of participation might vary depending on one‘s personal, social, situational, and cultural influences that eventually affect their intentions and behaviour on whether to continue or discontinue participating in that community. Facebook as a particular Web 2.0 community has been used as an exemplary case study in this research reflecting the drivers of its continuous usage in the Hashemite Kingdom of Jordan. Moreover, very few studies on Web 2.0 communities covered the Middle East area and more specifically there is almost absence of research in Jordan on how users of Facebook along with their cultural and behavioural influences would continue using this Web 2.0 community or not. Therefore, this study tackles this issue to investigate the influences affecting the continuous participation in these communities This research develops a conceptual framework that can be used as an instrument to guide empirical work in the field of Web 2.0 communities. The empirical context of the research is random Facebook users in Jordan, where data were analysed using quantitative and qualitative research approaches. Results and findings show that Personal attitude, subjective norms, and perceived behavioural control has shown to be all significant and highly influential on affecting users‘ intentions to continue participating on Facebook, perceived behavioural control (i.e. facilitating conditions, controllability) ranked the highest in its significance towards examining users’ intentions to continue participating on Facebook. Followed by the subjective norms (i.e. critical mass, compliance, and informational influences), then ranked the personal attitude (i.e. satisfaction, compatibility). Results have proved that most Facebook users in Jordan do participate on this site in the first place to deliver epistemic value elements, not with a much difference came the social value after, then ranked the hedonic third. The utilitarian value proved to be insignificant by all means, therefore, users intend to continue participating on Facebook despite of the perceived value elements to be delivered. Interestingly, analysis have proved the insignificance of the three cultural dimensions (i.e. masculinity vs. Femininity, individualism vs. Collectivism, and long-term vs. Short-term orientation), therefore, it has not been considered moderating in the framework of this research. Furthermore, the study concludes with specific implications for relevant theories, and useful findings on the individual, organizational, and the societal levels. Additionally, researchers in similar areas can find this work useful as a way to approach new streams in studying participation in Web 2.0 communities.

A continuous need for blood products, specifically for those who require frequent transfusions, such as individuals with sickle cell disease, warrants the need for targeted interventions to increase blood donations from underrepresented populations. One population in particular, African Americans, only account for 1% of blood donors in the United States. Literature indicates numerous reasons why this population is underrepresented amongst donors, including fear, lack of knowledge about the blood donation, and specific to this population, lack of trust in the medical community. This study involves the development, implementation, and assessment of a targeted educational approach, incorporating the Theory of Planned Behavior and various teaching methods, to motivate African Americans non-donors to attempt to donate blood. Participants attended a 1-hour educational session where they completed two surveys, one before the session and one directly after. A third survey was completed 2 months after the session. Of the 155 individuals enrolled in the study, 142 subjects were included in the data analysis. Sixteen percent of the study participants presented to donate as a result of attending the educational session. This resulted in a statistically significantly higher proportion of African Americans presenting to donate than the current proportion in Virginia. Analysis of results from the first two surveys indicated that subjective norm and attitude were significant predictors of one’s intent to donate blood, while perceived behavioral control was not a factor. The educational session increased survey scores related to intent to donate in comparison to scores obtained prior to the session. While this study resulted in a significant proportion of new donors, there is still a need for interventions that will focus specifically on changing attitudes toward blood donation and a need for methods to motivate African Americans to educate individuals in the community on the importance of becoming blood donors.

We use the labor force ad hoc module "transition from work into retirement" to analyze the link between individual as well as pension system characteristics and planned retirement age within the European Union. We find that timing of retirement is correlated between partners who are, already at the stage of retirement planning. In richer countries of the EU15, standard retirement age seems to have a larger effect on planned retirement age than in poorer EU15 states or in new EU member states. The effect of pension wealth is largest in the new EU member states and smallest in rich EU15 countries. Furthermore, industry and occupation effects differ by country type. (authors' abstract)

Master thesis is focused on one of the crutial and the most problematic tools at the same time of driver diagnostic which is the interwiev. In the theorethical part of the thesis we concern on the targets and basic starting points of the driver assesment, from which the explorative areas of the interwiev. We discuss the role of the interwiev in the systém of methods which can be used for driver behaviour prediction and its specific kontext or the social desirability influence. The interwiev is divided into four phases - introducion (contract), anmnestic data gathering, diagnostical part, and conclusion. The theory of planned behaviour, and Behavioral Event Interview are presented in the diagnosticlal as the two sources of the design of semi-standardized interview. Empirical part contains a specific interwiev design including the recommended question set for mapping of the ability to view and reflection, driving style and characteristics, attitudes to risk behavior a possibility of the driver change from the point of his behaviour.. Then, the qualitative assesment of the question sets using the contrast method, comparison and subsequent interpretation based on the content analysis of the driver statements in accompanying case reports. Based on the analysis of the driver statements we set several key...

The influence of online customer reviews (OCRs) on consumer behaviour has recently gained considerable attention, from both academic and business communities. Technology allows customers to freely and easily post their comments and opinions online about any product or service. These types of customer reviews can have a significant effect on customers’ purchase decisions and have become an essential part of the experience when shopping online. However, knowledge of the role of the perceived derived attributes of OCRs on consumer behaviour remains vague. Previous studies have mainly focused on the influence of the virtual attributes of OCRs, such as volume and valence, on consumers’ intentions, while limited attention has been paid to understanding the effects of the derived attributes. This study, thus, aims to understand the effects of the social and functional perceived derived attributes of OCRs on customer trust and intention to shop online. Hence, we develop a research model - Perceived Derived Attributes (PDA) -, based on the integration of social support with functional support derived from OCRs. The PDA model provides an in-depth understanding of the role of the social support of OCRs by applying and utilising theories of social support, social presence and a sense of belonging. The PDA model also investigates the influence of the functional support arising from OCRs through the inclusion of perceived control, from the Theory of Planned Behaviour (TPB) with the Technology Acceptance Model (TAM). The PDA model characterises perceived social support through informational and emotional supports, social presence, and a sense of belonging; whereas, functional supports are characterised by perceived usefulness, perceived ease of use, perceived enjoyment, and perceived control. A total of 489 responses to a survey were collected from users of amazon.com. The results from this study suggest that customer trust in an e-vendor and their intention to shop online are significantly affected by social and functional supports derived from OCRs. In particular, informational support, social presence and a sense of belonging, derived from OCRs were found to positively and significantly affect both customer trust in the online vendor and consumer behavioural intention. However, emotional support was only found to affect customers’ intentions and not their trust in the e-vendor. Additionally, customer trust in an e-vendor and their intention to shop online are significantly affected by perceived usefulness, perceived ease of use and perceived enjoyment of OCRs. Furthermore, the sense of control derived from OCRs significantly affects customer intention and significantly affects customer trust in e-vendors but only for customers who frequently check OCRs before making a purchase. This study is the first to introduce and empirically test the effects of perceived derived attributes of OCRs on customer trust and behavioural intention. Understanding the effects of such influencing factors is of utmost importance for both theoretical development and business practices. Clearly, these attributes of OCRs are linked to the development of the shopping environment, representing a promising marketing tool that positively affects customers’ behaviour.

In recent years, many health care organizations have begun to take advantage of computerized information systems to facilitate more effective and efficient management and processing of information. However, commensurate with the vastly innovative enhancements that computer technology has contributed to traditional paper-based health care information systems, are security vulnerabilities that have potentially devastating effects on these systems. To ensure the confidentiality, integrity, and availability of information and to ensure compliance with the Security Rule of the Health Insurance Portability and Accountability Act (HIPAA), health care organizations have implemented a number of security controls. Although the objectives of these controls are understood and acknowledged by users of computerized patient care information management systems, the controls are sometimes circumvented or ignored. The purpose of this study was the development of an instrument that measures key determinants of healthcare professionals' prudent access control behavior. The study examined healthcare professionals' prudent access control behavior using a model that integrates the Theory of Planned Behavior (TPB) and the Health Belief Model (HBM). Two additional variables - information security awareness and perceived information security responsibility were incorporated into the model. Rather than focusing on a single behavior or a few specific behaviors, a category of behaviors was proposed. Results of the study indicate that the HBM and TPB constructs as well as the two additional constructs included in the model are indeed key determinants of healthcare professionals' intention to engage in prudent access control behavior that mitigate security threats. Additionally, results of the study provide support for the partial mediating effects of perceived benefits and perceived responsibility for information security on attitude, information security awareness, subjective norm, perceived behavioral control, and perceived severity. The study contributes to the IS knowledge domain by providing theoretically grounded explanations for a subset of prudent information security behaviors of healthcare professionals.

The role that perceived information quality has on the intention to use a computer supported collaborative work (CSCW) system in the Federal Highway Administration is the focus of this study. The purpose of this study was to examine the functional diversity of the contributors in a CSCW as a major determinant of perceived information quality. The study relied on the Technology Acceptance Model (TAM), the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB) to propose a theoretical model which shows that perceived information quality influences perceived risk and trusting belief of the users of these systems. Both perceived risk and trusting belief shape the intention to use a computer supported collaborative work systems. This study conducted a web-based survey to validate the theoretical model. The study focused on the use of computer-supported collaborative work systems in the Federal Highway Administration. This study empirically validated the theoretical model. Scales were developed within the context of the variables (functional diversity, perceived information quality, perceived risk, trusting belief, and intention to use.) to survey discipline members at the Federal Highway Administration.The statistical results showed support for perceived information quality’s positive influence on trusting belief, perceived information quality’s negative influence on perceived risk, perceived risk’s negative influence on the intention to use a CSCW and trusting belief’s positive influence on the intention to use a CSCW. The results also showed there is no statistically significant difference in perceived information quality by functional diversity. This study concluded that the research model showed significant results to support four of the five hypotheses proposed and helped uncover key findings on how perceived information quality can be impacted. This research served as an original contribution to CSCW while working in functionally diverse teams environments.
