Potential and promise of online volunteering

The Internet is often perceived as yet another technological innovation that causes a further widening of the gap between rich and poor. However, one of the most interesting phenomena to come out of the Internet revolution is its utilization as a channel for social development. Volunteers working in task forces who were recruited through the net, work to improve the lives of many millions of people in need throughout the world. Some of these volunteers are ‘field workers’, working in physical proximity to those they are trying to help, while others may be sitting at home, using their computers to help needy populations many thousands of miles away. This paper studies this trend and advocates a model to explain the potential and promise of online volunteerism from the perspective of the volunteer. It is suggested that understanding the characteristics behind Internet volunteering from the perspective of the volunteer may enhance the positive potential of the Internet.     

Sex differences in purchasing textbooks online

In a series of studies, female students at an urban university tended to demonstrate fewer computer/Internet skills than male students, and their level of skill was a more consistent predictor of purchasing textbooks online. These results were not replicated at a rural state college with less computer-skilled students.     

Financial risk and its impact on new purchasing behavior in the online retail setting

This paper examines the effect of financial risk on perceptions of service quality and relationship-marketing quality in the online retail environment. Perceptions of financial risk were found to be negatively associated with service quality. In particular, a well-designed and attractive Web site was found to mitigate perceptions of financial risk during early trial-buy purchasing. Relationship-marketing quality was not affected by financial risk. This study adds to an enhanced understanding of how risk perceptions influence assessment of service quality and relationship-marketing quality. While the drivers of service quality and relationship-marketing quality have been examined extensively in the online setting, a surprising lack of research investigates the role of risk perceptions in the early stage, buy-trial purchasing behavior. This emerging area of research interest is deserving of more attention. Our findings provide valuable normative guidance to researchers interested in the affects of perceived risk (particularly financial risk) on new online shoppers, emphasizing the interdependency between Web site design and risk perceptions.     

The mediating effect of website quality on Internet searching behavior

The study investigates the mediating effect of website quality on Internet searching behavior. The research model incorporates three dimensions, namely (1) Internet attitudes of the Internet users, (2) website quality, including the system quality, service quality and information quality, and (3) Internet searching behavior demonstrated by the general population of Internet users. A survey instrument was used to gather data to exam the relationships in the proposed model. The collected online surveys (n = 856) are used to test the relationships among the three dimensions expressed in the proposed structural equation model. The results show that website quality has a mediating effect on Internet searching behavior. It is also discovered that there is significant correlation between Internet attitudes and website quality. This study contributes empirical data to the predominantly theoretical literature on Internet searching behavior in general and Internet attitudes and website quality in particular. It is, to a certain extent, common sense that website quality has a positive impact on Internet searching behavior. This paper takes an important step forward by detailing how website quality affects the Internet searching behavior via enhancing the effect of users’ Internet attitudes.     

Teenagers in social virtual worlds: Continuous use and purchasing behavior in Habbo Hotel

Social virtual worlds (SVWs) have become important environments for social interaction. At the same time, the supply and demand of virtual goods and services is rapidly increasing. For SVWs to be economically sustainable, retaining existing users and turning them into consumers are paramount challenges. This requires an understanding of the underlying reasons why users continuously engage in SVWs and purchase virtual items. This study builds upon Technology Acceptance Model, motivational model and theory of network externalities to examine continuous usage and purchase intention and it empirically tests the model with data collected from 2481 Habbo users. The results reveal a strong relationship between continuous usage and purchasing. Further, the results demonstrate the importance of the presence of other users in predicting the purchase behavior in the SVW. Continuous SVW usage in turn is predicted directly by perceived enjoyment and usefulness while the effect of attitude is marginal. Finally, perceived network externalities exert a significant influence of perceived enjoyment and usefulness of the SVW but do not have a direct effect on the continuous usage.     

Exploring the value of purchasing online game items

The aims of this paper are to: (1) modify the theory of consumption values in order to investigate online game users’ perceived value of purchasable game items, and (2) develop a new construct – the “integrated value of purchasing game items” – based on the modified theory of consumption values. We found that the enjoyment, character competency, visual authority, and monetary values are appropriate for describing how online game users perceive the value of game items. Utilizing second order analysis, the “integrated value of purchasing game items” was developed. To show the validity of the new construct, we developed a research model and tested it using the results of 327 valid questionnaires. Results revealed that the new construct is statistically significant in affecting users’ intention to purchase game items.

Communicative practices in an online financial forum during abnormal stock market behavior

We offered a new perspective on communication in computer-mediated environments by examining communicative practices used during discussion in an online financial forum about a listed company that was experiencing abnormal trading behavior. The analysis of communicative practices showed how the linguistic nature of the online forum allowed covert manipulation of inexperienced and unsuspecting forum participants - against all the norms and rules governing online financial forums. Based on our theoretical understanding of communicative practices, we found a discrepancy between the expectations of and the actual divergence from an ideal communicative environment free from distortion and manipulation that is normally assumed to govern online forums. The discrepancy, which remains largely concealed, can be seen as a major factor in the negative implications of online financial forums.     

Netiquette within married couples: Agreement about acceptable online behavior and surveillance between partners

The internet has become an integral part of many people’s everyday lives. It is unclear what its role is in maintaining intimate offline relationships and whether the use of the internet might cause conflicts between partners about what constitutes acceptable online behavior. An online survey of 920 married couples in the UK who used the internet investigated whether partners have similar netiquettes. There were high levels of agreement between married partners about the unacceptability of online infidelities; similarly they agreed more than two random individuals about the acceptability of entertainment activities which, in excess, might be addictive. Partners further showed high correspondence in surveillance behavior. Women were more concerned about their own and their partner’s behavior and were more likely to monitor their partner’s online activities. These findings suggest that a netiquette is developed and consciously or subconsciously negotiated within intimate relationships. Nevertheless, traditional gender differences as regards risk perception still hold; women are more likely to problematies their own and their partners behaviors.     

The role of atmospheric cues in online impulse-buying behavior

This study extends a stimulus–organism–response (S–O–R) model to include impulse-buying behavior, which plays a vital role in electronic shopping but has not gained much attention in e-commerce research. Grounding our research in environmental psychology, we test the effects of virtual atmospheric cues on online impulse-buying behavior and spending, via a consumer survey. The study applies elaborated mediating variables (shopping enjoyment and impulsiveness) to develop a structural model linking three categories of atmospheric cues of an electronic store (content, design, and navigation) to approach behavior variables (impulse-buying behavior and expenditure). The results support the validity of the S–O–R model in the context of online impulse-buying behavior and show a significant positive effect of two dimensions of virtual atmospheric cues (design and navigation).     

Investigation of online community voluntary behavior using cognitive map

It is difficult even for experts in organizational behavior to cognitively predict the causal effect of one factor on the others. A cognitive map is used to describe the inference process for the investigation of online community voluntary behavior. The investigation of online community voluntary behavior demands consideration of the complex causal effect from support for member communication, perceived community value, recognition for contribution, freedom of expression, and interactive communication, to community commitment, loyalty, and social participation. A standardized causal coefficient estimated in structural equation models (SEMs) is used to create a cognitive map illustrating the effect of the status of one component on the status of another component. The cognitive map provides preliminary insights into the direction of online community voluntary behavior toward maximizing community commitment, loyalty, and social participation.     

Differences among breast and prostate cancer online support groups

Online support resources have become viable alternatives to face-to-face support groups for cancer patients. It is important to understand how individuals make use of such online support resources and what, if any, differences exist between groups. A content analysis was conducted on 3203 posted messages to prostate and breast cancer support sites on Google Groups and WebMD. Overall, post-treatment survivors were the most common posters followed by spouses; however, the proportion of posters varied by site. For both groups, messages of support were most frequent. However the type of support varied by cancer type. Support messages on the breast cancer sites were mostly offers of emotional support. Conversely, messages of support on the prostate cancer sites focused on informational support. Messages of emotional well-being and medical-related comments were next most common on the breast cancer sites, whereas medical issues and sexual intimacy were on the prostate cancer sites. Overall, these findings identify several key differences in the use and benefits of online support sites for breast and prostate cancer.     

Computer-mediated group influence on ethical behavior

Drawing on previous research in ethical behavior in information technology, this study examines the effects of group discussion, using virtual teams, on an individual’s intention to behave ethically/unethically. It was hypothesized that behavioral intention would be influenced by an individual’s attitude (toward ethical behavior), personal normative beliefs, ego strength, locus of control, perceived importance, gender and the scenario, and that computer-mediated group discussion would impact an individual’s ethical behavioral intention. This was tested through an experiment using five different ethical scenarios involving information technology. The results show that for two of the five scenarios, individual behavioral intention was significantly more unethical after computer-mediated group discussion than before, while for one scenario, individual behavioral intention was significantly more ethical after computer-mediated group discussion than before. The results of this study may help organizations to develop realistic training programs for IT professionals that account for changes in employee’s personal ethical models after interacting with others.     

Consumer's decision to shop online: The moderating role of positive informational social influence

While much of the current literature tends to focus on the direct effect of social influence on consumer online shopping behavior, our study drew heavily on social influence theory and argued for an alternative theory focusing on the moderating role of social influence. In particular, we explored how positive messages in online discussion forums may affect consumers’ decisions to shop online. We used a laboratory experiment in which the treatment group was required to read positive messages about online shopping experience in an online discussion forum. Positive social influence was found to reinforce the relationship between beliefs about and attitude toward online shopping, as well as the relationship between attitude and intention to shop. We believe our alternative theory provides new insight into the complex processes through which social influence is brought to bear on consumers’ online shopping decisions. Implications of our work are discussed.     

Analyzing the emotional outcomes of the online search behavior with search engines

The affective component has been acknowledged as critical to understand information search behavior and user-computer interactions. There is a lack of studies that analyze the emotions that the user feels when searching for information about products with search engines. The present study analyzes the emotional outcomes of the online search process, taking into account the user’s (a) perceptions of success and effort exerted on the search process, (b) initial affective state, and (c) emotions felt during the search process. In addition, we identify profiles of online searchers based on the emotional outcomes of the search process, which allow us to differentiate the emotional processes and behavioral patterns that lead to such emotions. The results of the study stress the importance of the affective component of the online search behavior, given that these emotional outcomes are likely to influence all the subsequent actions that users perform on the Web.     

Fostering empowerment in online support groups

Online support groups have been used extensively, in numerous areas of distress, for 15 years. Researchers have presented conflicting findings and ideas about their effectiveness in helping people cope with respective problems. Our review of quantitative studies and our qualitative exploration of the nature of the experiences that occur in such groups show that several factors operate to potentially affect participants. Personal and interpersonal dynamics, which are central in producing effects in these groups, are induced and accelerated by the powerful online disinhibition effect. These factors, including the very impact of writing, expressions of emotions, collecting information and thereby improving understanding and knowledge, developing social relationships, and enhancing decision-making skills and consequent behavioral actions all serve as possible generators of a sense of personal empowerment for people in distress. This view may explain why empirical research has frequently found little or no specific outcomes from participating in online support groups; however, it has found much support for nonspecific personal impacts of this means of intervention. Thus, we contend that online support groups are designed to foster, and many of them actually do, well-being, a sense of control, self-confidence, feelings of more independence, social interactions, and improved feelings—all nonspecific but highly important psychological factors. As such, participating in an online support group could foster personal empowerment, which is much needed in handling specific conditions of distress. Nonetheless, this participation has potential costs, too, especially developing dependence, distancing from in-person contacts, and exposure to unpleasant experiences typical of social engagement in cyberspace.     

Contradictory deceptive behavior in online dating

Deceptive behavior is common in online dating because personal profiles can be easily manipulated. This study conducts two experiments to examine contradictory deceptive behavior in online dating. The results of Experiment 1 showed that users have lower perceptions of authenticity evaluations of daters’ self-provided photographs with strong physical attractiveness than for those with low physical attractiveness, and the authenticity perceptions of daters’ self-provided photographs have a positive relationship with the authenticity evaluation of online daters’ text-based self-presentations. Although users are suspicious of the authenticity of beautiful or handsome daters’ photographs, the results of Experiment 2 showed that people still employ higher levels of deception in self-presentations toward daters with highly attractive photographs to increase their possibilities of securing a date with those daters. The results also show that women employ higher levels of deception in self-presentation than men in online dating environments.
