Organizational members’ use of social networking sites and job performance: An exploratory study

– There is considerable debate among academics and business practitioners on the value of the use of social networking by organizational members. Some, fearing presenteeism (i.e. being at the workplace but working below peak capacity), claim that the use of social networking sites by organizational members is a waste of time, while others believe it leads to improvements in job performance, partly due to employees’ successful efforts to balance work‐life realms. This paper aims to inform this debate by examining the use of social networking sites by organizational members and its effect on job satisfaction, organizational commitment, and job performance., – The exploratory study is based on a survey of 193 employees, focusing on the following constructs: social networking site use intensity, perceived job satisfaction, perceived organizational commitment, and job performance. The authors’ proposed model was evaluated using variance‐based structural equation modeling (SEM), a latent variable‐based multivariate technique enabling concurrent estimation of structural and measurement models under nonparametric assumptions. This study used WarpPLS 2.0 to assess both the measurement and the structural model., – The results show that social networking site use intensity has a significant positive effect on job performance through the mediation of job satisfaction, and that this mediating effect is itself mediated – in a nested way – via organizational commitment. The findings suggest that social networking site use, rather than causing presenteeism, may be a new way through which employees balance their work‐life realms, in turn benefitting their organizations.Originality/value – To the best of the authors’ knowledge, this is the first study to analyze, in an integrated way, the relationship between those theoretical constructs.

Unveiling the dark side of social networking sites: Personal and work-related consequences of social networking site addiction

Abstract Although previous research has explored the effects of social networking site (SNS) use in organizations, researchers have focused little on its negative consequences. This article attempts to fill this void by examining, through the lens of social cognitive theory, the extent SNS addiction impacts personal and work environments. The results, based on 276 questionnaires completed by employees in a large information technology corporation, show that addiction to SNSs has negative consequences on the personal and work environments. SNS addiction reduces positive emotions that augment performance and enhance health. SNS addiction fosters task distraction, which inhibits performance. Theoretical and practical implications are discussed.

Statistical power with respect to true sample and true population paths: a PLS-based SEM illustration

Monte Carlo experiments aimed at assessing the statistical power of structural equation modelling SEM techniques typically focus on true population path coefficients, ignoring true sample path coefficients. We demonstrate the limitations stemming from such practice in statistical power assessments. This is done in the context of SEM techniques employing the partial least squares PLS method, where power claims have led to much recent debate. We show that the sample sizes at which power is greater than.8 differ significantly when we consider true population and true sample paths, and that the difference increases with decreases in the magnitudes of the paths being considered. Finally, we illustrate empirically how these differences affect the conclusions we can draw from the analysis of a relatively small sample of size 193.

A six-stage framework for evolutionary IS research using path models: Conceptual development and a social networking illustration

Purpose – The purpose of this study is to fill a gap in evolutionary theorizing in the field of information systems. Evolutionary theorizing has recently been added as a useful tool to the research repertoire of information systems investigators. However, the literature on evolutionary theorizing and related empirical research lacks a clear framework that explicitly shows how information systems researchers can go, step-by-step, from a generic model of the evolution of traits in our ancestral past to a more specific model depicting the effects of technology facilitation of those traits among modern humans. The purpose of this study is to fill this gap through a framework composed of six stages. Design/methodology/approach – To discuss and illustrate the framework, the authors develop an easy-to-understand generic path model explicitly depicting relationships among variables related to events that occurred in our evolutionary past. We then incrementally adapt this generic path model, eventually arriving at...

Does privacy matter to millennials? The case for personal cloud

ABSTRACT To date, there is little research on the extent to which privacy, security, and trust influence consumer technology-use decisions based on generation. We, therefore, examine, through the lens of the expectancy-valence theory, the extent to which privacy, security, and trust influence the decision to use personal cloud computing among millennials. We also examine the moderating effect of innovativeness on these relationships. Our structural equation modeling (SEM) analysis of 371 millennials shows that privacy is irrelevant for millennials when making decisions to use personal cloud and that individuals with high innovativeness tend to disregard security when making an adoption decision.

Social Media Sites Use Intensity and Job Burnout Among the U.S. and Thai Employees

This research explored the effect of social network sites SNS use intensity in the workplace on three aspects of job burnout. The data were collected from non-teaching employees from universities in the U.S. N = 174 and in Thailand N = 182. Results from partial least squares regression revealed some evidence of the u-curve relationship between SNS use intensity and depersonalization in both countries. However, the u-curve relationship between SNS use and lack of personal accomplishment is only supported in U.S. samples. This suggests that while a moderate degree of SNS use at work tends to lower burnout, a high degree of use appears to create more burnout. The results also reveal a strong positive linkage between SNS use intensity and emotional exhaustion in U.S. samples. Overall, these findings imply that allowing employees to use SNS can provide some benefits, but it is important that employees do not overuse SNS to avoid burnout.

The role of coworker and supervisor support on job burnout and job satisfaction

Purpose - This study investigates the role of coworker and supervisor support on three aspects of burnout (emotional exhaustion, depersonalization, perceived lack of personal accomplishment) and job satisfaction. The authors argue that different sources of social support at work can influence these three aspects of burnout differently. Design/methodology/approach - Questionnaires were delivered to supervisors of each campus department at two state universities in South Texas asking them to encourage their employees to complete the survey. The sample consisted of 174 personnel. Findings - The results show that coworker support was negatively associated with emotional exhaustion and depersonalization but not with perceived lack of personal accomplishment while supervisor support was negatively associated with all aspects of burnout. The analysis also confirmed the direct and indirect effects of coworker and supervisor support on job satisfaction. Practical implications - Due to the detrimental consequences of burnout to employee satisfaction, organizations need to make sure that employees receive sufficient support from their coworkers and supervisors to avoid this burnout problem. Originality/value - Even though the role of social support on job burnout has been previously investigated, existing studies tended to combine three dimensions of burnout into a single measure. Using an aggregated measure of burnout as an outcome variable can limit our understanding about the role that social support plays on each individual dimension of burnout. By employing burnout as a multidimensional construct, the present study can determine whether coworker support and supervisor support can have a different impact on each of the three dimensions of burnout.

Very Large Metastases to the Brain: Retrospective Study on Outcomes of Surgical Management

BACKGROUND The incidence of brain metastases is rising. To our knowledge, no published study focuses exclusively on brain metastases larger than 4 cm. We present our surgical outcomes for patients with brain metastases larger than 4 cm. METHODS This is a retrospective chart review of inpatient data at our institution from January 2006 to September 2015. Primary end points included overall survival, progression-free survival, and local recurrence rate. RESULTS Sixty-one patients had a total of 67 brain metastases larger than 4 cm: 52 were supratentorial and 15 were infratentorial. Forty-three patients underwent surgical resection. Average duration of disease freedom after resection was 4.79 months (range, 0-30 months). Excluding patients with residual on immediate postoperative magnetic resonance imaging, the average rate of local recurrence was 7 months (range, 1-14 months). Overall survival after surgery excluding patients who chose palliation in the immediate postoperative period averaged 8.76 months (range, 1-37 months). Thirty-five of 43 patients (81.4%) had stable or improved neurologic examinations postoperatively. Six patients (13.95%) developed surgical complications. There were 3 major complications (6.98%): 2 pseudomeningoceles required intervention and 1 postoperative hematoma required external ventricular drain placement. There were 3 minor complications (6.98%): 1 self-limited pseudomeningocele, 1 subgaleal fluid collection, and 1 postoperative seizure. CONCLUSIONS Surgery resulted in stable or improved neurologic examination in 81.4% of cases. On statistical analysis, significantly increased overall survival was noted in patients undergoing surgical resection, and those with higher Karnofsky Performance Scale and lower number of brain metastases at presentation. There is a need for further studies to evaluate management of brain metastases larger than 4 cm.

Media Naturalness and Compensatory Adaptation: Counterintuitive Effects on Correct Rejections of Deceitful Contract Clauses

Research problem: Deciding whether to accept or reject contract clauses in software purchasing contracts is a complex communication-related task, which is likely faced daily by a multitude of software purchasing professionals in a variety of organizations. Research question: What are the effects of viewing contract clauses as video clips, compared to viewing clauses as text only, in terms of cognitive effort, communication ambiguity, and correctness in the acceptance or rejection of clauses in software purchasing contracts? Literature review: The literature on the Media Richness and Media Naturalness theories suggest that viewing contract clauses as video clips should reduce cognitive effort and communication ambiguity. However, while Media Richness theory suggests that correctness in the acceptance or rejection of clauses in software purchasing contracts should increase with the use of video clips, Media Naturalness theory suggests a neutral overall effect. Methodology: An experiment was conducted in which student participants were asked to either accept or reject 20 clauses from a software contract, placing themselves in the position of buyers. Of the 20 clauses, 6 were intentionally deceitful and potentially harmful to the buyer. Approximately half of the participants reviewed the contract clauses as web-based text, and the remaining as web-based video clips. Results and conclusions: Viewing contract clauses as video clips was associated with significantly less cognitive effort and less communication ambiguity than viewing the clauses as text only. Counterintuitively, increases in perceived cognitive effort and communication ambiguity were associated with more successful identification and rejection of deceitful contract clauses. The combination of these competing effects led to an overall neutral effect of the medium on the correctness in the acceptance or rejection of clauses. These findings are consistent with expectations based on Media Naturalness theory, particularly its compensatory adaptation proposition, and inconsistent with expectations based on Media Richness theory.
