The Effects of Multi-identity on One’s Psychological State and the Quality of Contribution in Virtual Communities: A Socio-Psychological Perspective

서아영,신경식,이주민 한국경영정보학회 2010 Asia Pacific Journal of Information Systems Vol.20 No.1

In a virtual community, one can possess multiple identities and pretend to be different by creating self-identity in contrast with his or her actual self. Does false identity undermine the qualitative growth of a virtual community by reducing members’ accountability? Or does it stimulate their contributive behaviors by ensuring freedom of speech? It is imperative to understand the effects of multi-identity considering the distinct properties of a virtual community in which people easily change their identities at little or no cost. To answer these questions, we adopted the concept of self-discrepancy from the social psychology theory rooted in the concept of the self and developed a theoretical model to predict quality of contribution of the individual member in virtual communities. Based on the self-discrepancy theory, we first identified two different domains of the self: (1) an “actual self” that consists of attributes that the person believes he or she currently possesses in real life and (2) a “cyber self” that consists of attributes the person believes he or she possesses in a virtual community. Next, we derived an index for two different types of self-discrepancy by using the differences between the actual and the cyber identities: Personal Self-discrepancy and Social Self-discrepancy. Personal Self-discrepancy reflects the degree of discrepancy between actual and cyber identity regarding a person’s intelligence, education, and expertise. Social Self-discrepancy reflects the degree of discrepancy between actual and cyber identity regarding a person’s morality, sociability, and accordance with social norms. Finally, we linked them with sense of virtual community, perceived privacy rights, and quality of contribution to examine how having a multi-identity influences an individual’s psychological state and contributive behaviors in a virtual community. The results of the analysis based on 266 respondents showed that Social Self-discrepancy negatively influenced both the Sense of Virtual Community and Perceived Privacy Rights, while Personal Self-discrepancy negatively influenced only Perceived Privacy Rights, thereby resulting in reduced quality of contribution in virtual communities. Based on the results of this analysis, we can explain the dysfunctions of multi-identity in virtual communities. First, people who pretend to be different by engaging in socially undesirable behaviors under their alternative identities are more likely to suffer lower levels of psychological wellbeing and thus experience lower levels of sense of virtual community than others. Second, people do not perceive a high level of privacy rights reflecting catharsis, recovery, or autonomy, even though they create different selves and engage in socially undesirable behaviors in a virtual community. Third, people who pretend to be different persons in terms of their intelligence, education, or expertise also indirectly debase the quality of contribution by decreasing perceived privacy rights. The results suggest that virtual community managers should pay more attention to the negative influences exercised by multi-identity on the quality of contribution, thereby controlling the need to create alternative identities in virtual communities. We hope that more research will be conducted on this underexplored area of multi-identity and that our theoretical framework will serve as a useful conceptual tool for all endeavors.

With the advent of communication technologies including electronic collaborative tools and conferencing systems provided over the Internet, virtual collaboration is becoming increasingly common in organizations. Virtual collaboration refers to an environment in which the people working together are interdependent in their tasks, share responsibility for outcomes, are geographically dispersed, and rely on mediated rather than face-to face, communication to produce an outcome. Research suggests that new sets of individual skill, knowledge, and ability (SKAs) are required to perform effectively in today’s virtualized workplace, which is labeled as individual virtual competence. It is also argued that use of online social networking sites may influence not only individuals’ daily lives but also their capability to manage their work-related relationships in organizations, which in turn leads to better performance. The existing research regarding (1) the relationship between virtual competence and task performance and (2) the relationship between online networking and task performance has been conducted based on different theoretical perspectives so that little is known about how online social networking and virtual competence interplay to predict individuals’ task performance. To fill this gap, this study raises the following research questions:(1) What is the individual virtual competence required for better adjustment to the virtual collaboration environment?(2) How does online networking via diverse social network service sites influence individuals’ task performance in organizations?(3) How do the joint effects of individual virtual competence and online networking influence task performance?To address these research questions, we first draw on the prior literature and derive four dimensions of individual virtual competence that are related with an individual’s self-concept, knowledge and ability. Computer self-efficacy is defined as the extent to which an individual beliefs in his or her ability to use computer technology broadly. Remotework self-efficacy is defined as the extent to which an individual beliefs in his or her ability to work and perform joint tasks with others in virtual settings. Virtual media skill is defined as the degree of confidence of individuals to function in their work role without face-to-face interactions. Virtual social skill is an individual’s skill level in using technologies to communicate in virtual settings to their full potential. It should be noted that the concept of virtual social skill is different from the self-efficacy and captures an individual’s cognition-based ability to build social relationships with others in virtual settings. Next, we discuss how online networking influences both individual virtual competence and task performance based on the social network theory and the social learning theory. We argue that online networking may enhance individuals’ capability in expanding their social networks with low costs. We also argue that online networking may enable individuals to learn the necessary skills regarding how they use technological functions, communicate with others, and share information and make social relations using the technical functions provided by electronic media, consequently increasing individual virtual competence. To examine the relationships among online networking, virtual competence, and task performance, we developed research models (the mediation, interaction, and additive models, respectively) by integrating the social network theory and the social learning theory. Using data from 112 employees of a virtualized company, we tested the proposed research models. The results of analysis partly support the mediation model in that online social networking positively influences individuals’ computer self-efficacy, virtual social skill, and virtual media skill, which are key predictors of individuals’ task performance. Furthermore, the resul...

강판으로 전단보강한 플랫 플레이트의 뚫림전단 성능 평가

서아영,조은선,김민숙,최봉섭,김희철,이영학 한국방재학회 2015 한국방재학회논문집 Vol.15 No.2

In this paper, flat plates reinforced by plates with openings made of steel are tested and evaluated punching shear capacity. 8 specimens including non-reinforced specimens, reinforced with stirrups, GFRP plates, and steel plates are tested. Based on the test result, load-displacement curves, crack and failure mode are compared and analyzed. Test result of specimens reinforced by steel plates showed higher maximum load and larger displacement than non-reinforced specimen and specimen reinforced by stirrup. Specimens reinforced by steel plates showed similar shear capacity with specimens reinforced by GFRP plates. But crack has occurred with larger area in specimens reinforced by steel plates than specimens reinforced by GFRP plates. And compared shear strength of specimens with calculated shear strength by ACI 318-11, Eurocode 2, and BS 8110 codes. And judged availability of shear reinforcement spacing by ACI 318-11. 본 논문에서는 강재로 제작된 유공형 판 형상의 전단보강재를 적용한 플랫 플레이트에 실험을 수행하여 뚫림전단 성능을 평가하였다. 무보강 시험체와 철근 스터럽, GFRP판, 강판으로 전단보강된 총 8개 시험체의 하중-변위 곡선, 시험체 균열 및 파괴 양상을 비교·분석하였다. 실험 결과, 강판으로 전단보강한 경우, 무보강 시험체와 철근 스터럽으로 전단보강한 시험체에 비해 다소 높은 최대 하중과 큰변위를 나타내었다. 강판 보강 시험체는 GFRP판 보강 시험체와 유사한 전단성능을 보였으나, 더 넓은 면적에서 균열이 발생하였다. 또한 ACI 318-11, Eurocode 2, BS 8110 기준에 의해 산정한 전단강도와 실험을 통해 얻은 전단강도를 비교하였으며, ACI 318-11에서 제시하는 최대 전단보강 간격 기준의 적용성을 평가하였다.
