Based on the self-evaluation maintenance model and social comparison theory, the purpose of this study is to test a novel model to explore the influence of competitive psychological climate on knowledge withholding of employees with the mediating role of envy. This study also investigated when the effect of climate on envy is more pronounced by assessing the role of a narcissistic personality.

The authors collected time-lagged data from 376 employees working in UAE national banks to test the model.

The findings of this study showed that a competitive psychological climate indirectly affects knowledge withholding behaviour because such a climate enhances the emotional response of employee envy. In a competitive climate, upward social comparisons are likely to be heightened, resulting in employee envy and knowledge withholding because knowledge is used as leverage to gain self-control and self-worth in the organisation. This effect of such a climate on employee envy was found to be stronger when employees have a narcissistic personality.

The findings offer practical insights to managers and practitioners on the importance of managing the competitive climate cautiously to address the likelihood of knowledge withholding behaviour among employees at work.

Knowledge withholding is an important but under-studied topic, which refers to the phenomenon that individuals give less than full effort to contributing knowledge. This study aims to investigate the differential effects of task characteristics on individuals’ knowledge withholding behavior in online space, this study develops and empirically verifies a theoretical model that covers the five core task characteristics in job characteristics model (autonomy, identity, feedback, skill variety and significance), knowledge sharing self-inefficacy and withholding effort in sharing knowledge.

Using an online survey method, this study collected empirical data from 351 general internet users from 30 provincial administrative units in China. The data were analyzed using the structural equation modeling technique of partial least squares.

The analysis results indicate that autonomy negatively affects, while identity, skill variety and significance positively affect users’ knowledge withholding behavior in online space through the mediation of knowledge sharing self-inefficacy, and that three task characteristics (autonomy, identity and feedback) strengthen the relationship between knowledge sharing self-inefficacy and knowledge withholding.

This study provides valuable insights for reducing knowledge withholding behavior in online space. Operationally, different levels of task characteristics such as autonomy, identity and feedback can be set to prevent users from perceiving themselves as inefficacious, and to weaken the behavioral expression of knowledge sharing self-inefficacy.

This study provides a comprehensive understanding of the differential effects of task characteristics on knowledge withholding in online space, and improves the cognition of the boundaries of withholding effort in sharing knowledge in online space.

Drawing on the stress and coping theory, conservation of resources (COR) theory and social role theory, this study aims to investigate the impact of social media overload on knowledge withholding behavior and examine the gender differences in social media overload, engendering knowledge withholding.

By hiring a professional online survey company, this study collected valid responses from 325 general social media users. The structural equation modeling (SEM) technique, bootstrapping method and multi-group analysis were used to test the proposed theoretical model.

The empirical results reveal that three types of social media overload positively affect users' knowledge withholding behavior and that emotional exhaustion significantly mediates the above relationships. The multi-group analysis demonstrates that gender differences do exist in the decision-making process of knowledge withholding; for example, females are more likely than males to become emotionally exhausted from social media overload, while males are more likely than females to engage in knowledge withholding behavior in the case of emotional exhaustion.

This study contributes to the existing body of knowledge by examining the relationship between social media overload and knowledge withholding, verifying the mediating role of emotional exhaustion as the key mechanism linking them, and narrowing the research gap of lacking gender differences research in knowledge withholding literature.

The U.S. government mandates taxpayers remit taxes through a "pay as you go" system. Research indicates employees continue to overpay interim taxes, despite the inefficiencies of this form of forced savings. Theory holds that a rational individual would choose the minimum amount of withholdings prescribed by the tax code. We adopted Kahneman-Tversky (1979) prospect theory to show that, under reasonable conditions, individuals will continue to choose excessive withholdings. This paper is not an attempt to statistically justify prospect theory however; we argue that withholdings increase when the income tax rate increases and when beforetax income increases. Our model extends the income tax withholding literature by modeling a framework to determine an optimal withholding decision for taxpayers.

The purpose of this paper is to gain a greater understanding of fear-based information withholding in project-manager-to-project-sponsor (PM2PS) communication and to propose future research directions.

The research consisted of a review of the literature related to the withholding of information in subordinate-to-superior communication and in PM2PS communication. Literature from project communication studies and literature from general communication theory was consulted.

Using defensive silence theory as a conceptual framework, five research propositions specific to fear-based information withholding in PM2PS communication are offered.

The study findings are limited to PM2PS communication based upon fear. The study provides a foundation for further research in this area within the conceptual framework of defensive silence theory.

The practical implication of this paper is that certain perceptions and behaviors of a project sponsor can be related to fear-based information withholding in PM2PS communication.

The originality of this paper is that it extends defensive silence theory into the realm of PM2PS communication. The value of this paper is to provide a catalyst for subsequent empirical-based research in order gain greater insight into fear-based information withholding in PM2PS communication.

This chapter discusses why employees keep their knowledge to themselves. Despite managers’ best efforts, many employees tend to hoard knowledge or are reluctant to share their expertise with coworkers or managers. Although many firms have introduced specialized initiatives to encourage a broader dissemination of ideas and knowledge among organizational members, these initiatives often fail. This chapter provides reasons as to why this is so. Instead of focusing on why individuals might share their knowledge, however, we explain why individuals keep their knowledge to themselves. Multiple perspectives are offered, including social exchange, norms of secrecy, and territorial behaviors.

The purpose of this paper is threefold; first, to give a background to the security of payment problem in the New South Wales construction industry and the problem giving rise to the Building and Construction Industry Security of Payment Amendment Act 2010 (NSW) (“2010 Amendment Act”); second, to provide an analysis of the operation of the 2010 Amendment Act; and finally, to address the main implications of the amendments for the three parties involved, namely the claimant, the respondent and the “Principal contractor”.

A review of the relevant literature was undertaken on the security of payment problem in the NSW construction industry and the problem giving rise to the 2010 Amendment Act. A “black‐letter” approach is adopted to analyse and explain the provisions contained in the 2010 Amendment Act. At the time of writing, no case law relevant to the amendments had been published.

The amendments brought about by the 2010 Amendment Act add appreciably to the scope of the Building and Construction Industry Security of Payment Act 1999 (NSW). The effect of the procedure under the 2010 Amendment Act is similar to that under the Contractors Debts Act 1997 (NSW). The 2010 Amendment Act enables a claimant to “freeze” money in the hands of the Principal contractor pending an adjudication, thereby increasing the chance of recovery of the adjudicated amount by the claimant. If, under this new procedure, the Principal contractor fails to “freeze” the monies, the Principal contractor will be liable (along with the respondent) for the amount owed to the claimant. There is a potential for the amendments to be used unfairly by claimants to coerce settlement of unmeritorious payment claims.

The analysis of the 2010 Amendment Act presented in this paper may be of interest in international jurisdictions where statutory adjudication for the construction industry has been introduced or is being contemplated.

While spontaneous and voluntary knowledge contribution in online communities promotes value co-creation, dysfunctional knowledge behaviors hamper the effectiveness and development of such communities. The study conceptualizes physicians' proactive knowledge sharing and knowledge withholding behaviors in physician-driven online health communities (OHCs) and integrates the theories of role identity as well as communal and exchange relationships to understand the root causes and motivations behind these two types of knowledge behaviors.

The authors collected survey data from 166 users from one of the largest physician-driven OHCs in China and applied the covariance-based structural equation modeling approach to test the hypotheses.

The findings suggest that (1) physicians' professional role identity had a positive indirect effect on proactive knowledge sharing behaviors through communal motivation, and work pressure weakened this indirect effect; and (2) professional role identity had a negative indirect impact on knowledge withholding behaviors through exchange motivation.

This study extends proactive knowledge sharing and knowledge withholding behaviors from the organizational management domain to the online environment, exploring the underlying causes and motivations behind both behaviors in the unique context of physician-driven OHCs. The findings offer practical suggestions for the effective management of OHC platforms, as well as policy implications that respond to the workforce shortage of healthcare providers, a crisis that is unfolding globally.

Although relational commitment increases the likelihood that intimates will confront each other about relational problems, commitment may promote decisions to withhold complaints in some circumstances. We conducted a survey of undergraduate daters that focused on the conditions under which relational commitment prompts individuals to express or withhold relational complaints. As expected, we documented a positive association between relational commitment and the willingness to confront a partner; the magnitude of this association was stronger among respondents who had dated for less than a year compared to those who had been involved for a longer time. Despite this general trend, we also found that relational commitment was positively associated with withholding grievances because the respondent believed that the problem was minor and perceived the partner would not change. Finally, we observed an interaction between relational commitment and partner's supportiveness when predicting the number of complaints withheld. Among individuals who were not very committed to their relationships, the association between partner supportiveness and the number of irritations withheld was negative and statistically significant. Among highly committed respondents, the same association was positive and not significant.
