The use of social networking sites, such as Facebook, in the job application screening process has changed the recruitment landscape. Many human resource (HR) professionals and recruiters have begun to use social networking sites as a tool to attract, source and screen potential candidates. When screening candidates’ Facebook profiles, recruiters make personality judgements that have important consequences for hiring decisions. However, little is known about what makes a good judge of personality in the world of online screening for recruitment. This study investigated the relationship between recruiters’ Big Five personality traits (extraversion, agreeableness, conscientiousness, openness to experience and neuroticism) and their ability to judge accurately candidates’ personality traits from their Facebook profiles. In particular, distinctive accuracy measures were employed which account for personality profile normativeness, or the degree to which applicants being rated are generally alike – an important limitation of earlier profile accuracy measures. Results from 456 university students who judged five actual Facebook profiles for which ‘true score’ estimates on personality traits were possible, revealed that recruiters were generally able to infer applicants’ personality traits from their Facebook profiles. However, recruiter personality was not an important factor in their judgement accuracy, neither when accuracy was operationalised as traditional profile accuracy measures, nor as distinctive accuracy.

Social commerce has evolved through the advancement of web 2.0 technologies, the significant rise of smartphone usage, and the increased popularity of social media platform usage such as social networking sites. Social networking sites have unique social sharing capabilities, which enable consumers to research products and services and make informed shopping decisions based on the trust developed in their online community. Brands acknowledge the importance of building and gaining consumer trust, because trust is a significant determinant for successful online transactions. Trust is equally essential to social commerce success, and is established as a positive influence on purchase intention. Considering the impact of trust on the consumer decision-making journey online, how this trust develops and what moderates this trust are of equal significance to brands and academics. Despite the plentiful research conducted in social commerce, the moderating role of culture on trust in social commerce is questioned, and the uncertainties of its impact within an emerging country is evident through insufficient academic research. The research design used in this study was cross-sectional in nature. Quantitative data were collected from a sample of social commerce users though an online survey administered on a branded Facebook page. Adopting an integrative social commerce framework by Kim and Park (2013) and the national cultural framework of Hofstede, the findings demonstrated a positive relationship between trust and purchase intention, and no moderation of culture on trust. Reinforcing previous academic research on the significance of trust in social commerce – further recommendation is given on the exploration of culture on trust and purchase intention.

Baby boomers are the largest age cohort in the United States, making up approximately 20% of the population. This cohort is faced with global problems that contribute to perceived loneliness and a lack of socialization. Additionally, baby boomers have an increased online presence on Facebook (FB), yet little is known about this age group and FB use. This research study addressed this issue with an examination of the relationships between overall perceived loneliness, socialization efficacy, and FB use. The theoretical framework that guided this study was Bandura's social learning theory, which was used to examine the effects of social reinforcement. Participants, those born between 1946 and 1964, (n = 97) were asked to share 2 months of FB activity, including the number of FB friends, number of postings, types of postings, quotes included, status updates, articles reposted, and whether friends were tagged in their posts. The FB variables were correlated with perceived loneliness, as measured by the Revised UCLA Loneliness Scale, and socialization efficacy, as measured by the Social Skill Scale, through a stepwise multiple regression analysis. The findings did not yield any statistically significant relationships between the FB variables and loneliness or socialization efficacy among baby boomers. These findings imply that other factors not studied here are promoting the increase in baby boomer FB use. The social change implications include mental health clinicians having a deeper knowledge base of baby boomers' FB use and an accurate portrayal of this cohort for increased treatment effectiveness, as baby boomers are portrayed as being lonely, isolated, and technologically challenged, which was not empirically supported in this study.

Social networking has become an integral part of daily communication and information sharing. Although researchers continue to explore the fields of social networking and emotion regulation separately, there is a lack of research bridging these areas of interest, particularly in the adolescent population. The purpose of this study was to examine the predictive relationship between the environmental and social variables of Facebook use, online social connectedness, and quality of parent-child relationship with adolescent emotion regulation. Fogel's social process theory of emotion provided the framework for this study and allowed for examination of the social networking environment. Research questions addressed independent variables of Facebook use, online social connectedness, and quality of parent-child relationship as well as interactions. Hypotheses were directed at different facets of emotion regulation including emotional control, emotional self-awareness, and situational responsiveness. A sample of 80 adolescents 13- to 18-years old was gathered through snowball sampling of Facebook groups and pages targeting parents of adolescents. Individual multiple regressions were used to examine prediction and interaction among variables. Results showed greater Facebook use predicted decreased emotional self-awareness and greater quality of parent-child relationship predicted improved emotional control in adolescents. The findings of this study promote positive social change by implicating the role of social networking use in predicting maladaptive adolescent emotional development and well-being. Future research will benefit from a larger sample size and include various social networking platforms along with gender and age-specific data.

Insider threat by employees in organizations is a problematic issue in today’s fast-paced, internet-driven society. Gone are the days when securing the perimeter of one’s network protected their business. Security threats are now mobile, and employees have the ability to share sensitive business data with hundreds of people instantaneously from mobile devices. While prior research has addressed social networking topics such as trust in relation to information systems, the use of social networking sites, social networking security, and social networking sharing, there is a lack of research in the mindfulness of users who spill sensitive data contained within images posted on social networking sites (SNS). The author seeks to provide an understanding of how non-malicious spillage through images relates to the mindfulness of employees, who are also deemed insiders. Specifically, it explores the relationships between the following variables: mindfulness, proprietary information spillage, and spillage of personally identifiable information (PII). A quasi-experimental study was designed, which was correlational in nature. Individuals were the unit of analysis. A sample population of business managers with SNS accounts were studied. A series of video vignettes were used to measure mindfulness. Surveys were used as a tool to collect and analyze data. There was a positive correlation between non-malicious spillage of sensitive business, both personally identifiable information and proprietary data, and a lack of mindfulness.

Today we are experiencing a rapidly increasing trend to use social networking in ways that dramatically affect both our personal and our public lives. This is a global phenomenon being experienced around the world. Exactly how this technology is being used and by whom is of great interest. The problem is that not a lot of research has been conducted to investigate the role social networking sites play to influence a person’s attitude toward sharing knowledge at work. In light of the marked increase in the use of social networking sites and how it is changing the way we live, both at work and during leisure activities, this research examines the factors that influence our attitudes towards knowledge sharing. This study presents the results of a quantitative research to understand the nature and impact of these motivating factors and analyzes how they influence our attitudes regarding the use of social networking sites as a venue in which to share knowledge. This study was conducted by means of an Internet survey. A self-administered questionnaire provided data and assisted in determining the degree to which the use of social networking sites is being used to share knowledge in the workplace. This non-experimental, cross-sectional, correlational study was conducted by means of quantitative research procedures to investigate the impact and influence social networking has on the knowledge transfer process. This research showed how social networking has redefined the collaborative environment that encourages knowledge holders to share their valuable knowledge. The results show that some factors, such as organizational climate, the subjective norm, and knowledge sharing attitudes, have a dominant impact on our behavior regarding the use of social networking sites and our intention to share knowledge with others. Another set of factors influenced our behavior and attitudes, but to a lesser degree, while one factor, anticipation of extrinsic rewards, actually exerted a negative influence on an individual’s knowledge sharing attitudes. The results of this dissertation increased and contributed to our understanding of the relationship between social networking sites and intention to share knowledge and set the stage for follow-on research.

This study proposes that individual personality characteristics and behavioral triggering effects come together to motivate online victimization. It draws from psychology’s current understanding of personality traits, attribution theory, and criminological research. This study combines the current computer deviancy and hacker taxonomies with that of the Dark Triad model of personality mapping. Each computer deviant behavior is identified by its distinct dimensions of cyber-criminal behavior (e.g., unethical hacking, cyberbullying, cyberstalking, and identity theft) and analyzed against the Dark Triad personality factors (i.e., narcissism, Machiavellianism, and psychopathy). The goal of this study is to explore whether there are significant relationships among the Dark Triad personality traits and specific cyber-criminal behaviors within social network sites (SNSs). The study targets offensive security engineers and computer deviants from specific hacker conferences and from websites that discuss or promote computer deviant behavior (e.g., hacking). Additional sampling is taken from a general population of SNS users. Using a snowball sampling method, 235 subjects completed an anonymous, self-report survey that includes items measuring computer deviance, personality traits, and demographics. Results yield that there was no significant relationship between Dark Triad and cyber-criminal behaviors defined in the perceived hypotheses. The final chapter of the study summarizes the results and discusses the mechanisms potentially underlying the findings. In the context of achieving the latter objective, exploratory analyses are incorporated and partly relied upon. It also includes a discussion concerning the implications of the findings in terms of providing theoretical insights on the Dark Triad traits and cyber-criminal behaviors more generally.

This dissertation contributes to IS research by explaining user intentions while using AR features in mobile social networking and retail app contexts. It consists of three essays, which use partial least squares modeling to analyze different consumer behavior models. The first essay examines the influence of quality, human, and environmental factors on AR reuse intention in a mobile social networking context. The second essay introduces position relevance, a new construct essential to AR research in e-commerce, and it looks at the influence of this construct and app involvement on user purchase intention, while using view-in-room features on mobile retail apps. The third essay examines the influence of service quality and visual quality on recommendation intention of mobile retail apps while using view-in-room features compared to shopping without using these AR features.

This empirical investigation sheds new light on a neglected topic of research on mobile phone use among the youth population of refugees that can help understand better how vulnerable youth can maximize the use of available resources in an active attempt to reduce their distresses and overwrite a better future for themselves and their families. Therefore, in light of James Coleman's social capital theory, I examined the use of mobile phones and social networking sites among 64 young Syrian refugees aged between 14 and 25 years old living in Lebanon. / 博士(グローバル社会研究) / Doctor of Philosophy in Global Society Studies / 同志社大学 / Doshisha University
