AbstractPurpose -The purpose of this paper is to examine why and when employees hide knowledge. Individuals may tend to hide knowledge when they have strong psychological ownership feelings over knowledge. Therefore, this research builds and tests a theoretical model linking knowledge-based psychological ownership with knowledge hiding via territoriality.Design/methodology/approach -Data were collected from knowledge workers in China via a three-wave web-based survey. The final sample was 190 cases. Hierarchical regression models and a bootstrapping approach were used to test the hypotheses.Findings -The results show that knowledge-based psychological ownership positively affects knowledge hiding. Territoriality fully mediates the link between knowledge-based psychological ownership and knowledge hiding. Moreover, organization-based psychological ownership moderates the positive link between territoriality and knowledge hiding. Specifically, territoriality will mediate the indirect effect of knowledge-based psychological ownership on knowledge hiding when organization-based psychological ownership is low, but not when it is high.Research limitations/implications -The research reflects that to reduce knowledge hiding, organizations should focus on practices that can decrease employees' self-perception of possession of knowledge and territoriality and that can strengthen employees' psychological ownership for organizations.Originality/value -Although many actions have been adopted to foster knowledge management in companies, knowledge hiding is still prevalent in work settings. This paper highlights the predictive power of knowledge-based psychological ownership on knowledge hiding, and the mediating role of territoriality in the link between knowledge-based psychological ownership and knowledge hiding.

Poly(e-caprolactone) (PCL)/layered double hydroxide (LDH) nanocomposites were prepared successfully via simple solution intercalation. The nonisothermal melt crystallization kinetics of neat PCL and its LDH nanocomposites was investigated with the Ozawa, Avrami, and combined Avrami-Ozawa methods. The Ozawa method failed to describe the crystallization kinetics of the studied systems. The Avrami method was found to be useful for describing the nonisothermal crystallization behavior, but the parameters in this method do not have explicit meaning for nonisothermal crystallization. The combined AvramiOzawa method explained the nonisothermal crystallization behavior of PCL and its LDH nanocomposites effectively. The kinetic results and polarized optical microscopy observations indicated that the addition of LDH could affect the mechanism of nucleation and growth of the PCL matrix. The Takhor model was used to analyze the activation energies of nonisothermal crystallization.

Purpose – The purpose of this paper is to investigate the relationship between job- and organization-based psychological ownership. In addition, the authors explored the emergence and outcomes of psychological ownership in Chinese context. Design/methodology/approach – Time-lagged survey data from 158 Chinese participants were used to test several hypothesized relationships employing partial least square techniques. Findings – Job-based psychological ownership appeared to mediate the relationship between experienced job control and organization-based psychological ownership. In addition, a statistically significant relationship between job-based psychological ownership and job satisfaction, organizational citizenship behaviors and turnover intentions, and a statistically significant relationship between organization-based psychological ownership and job satisfaction were observed. A negative relationship between organization-based psychological ownership and knowledge withholding was also observed. Practical implications – Managers who want to enhance employees’ job- and ultimately organization-based psychological ownership should empower their employees by enabling them to exert control over their work. Originality/value – This paper examined how organization-based psychological ownership emerges from control over work via job-based psychological ownership. The authors also investigated the impact of psychological ownership in Chinese context.

The purpose of this study was to investigate the frequency and antecedents of Chinese knowledge workers’ counterproductive work behavior (CWB) by using a self‐developed indigenous scale. The paper consisted of two studies. Study 1 developed an indigenous measure of knowledge workers’ CWB. Study 2 investigated the frequencies and antecedents of Chinese knowledge workers’ CWB using the indigenous measure with a sample of 366 participants. The results showed that CWB among Chinese knowledge workers was rather prevalent. The results also showed that personality variables (i.e., agreeableness, conscientiousness, neuroticism, and locus of control) were more important than other variables (e.g., demographic and job characteristics) in predicting CWB.

In this paper, Co-Al layered double hydroxide (LDH) and montmorillonite (MMT) have been exfoliated into charged single layers in the solvent of formamide and water, respectively. The structures of individual layers of LDH and MMT were characterized by X-ray diffraction (XRD) and atomic force microscopy (AFM). The delamination mechanisms of LDH and MMT were also discussed. Furthermore, heterogeneous ultrathin films of poly(vinyl alcohol) (PVA)/charged inorganic nanosheets, (PVA/MMT/PVA/LDH)(n), were fabricated by layer-by-layer (LBL) assembly via hydrogen bonding. The LBL assembly process was monitored by UV-vis spectroscopy, and the structures of the heterogeneous ultrathin films were analyzed by XRD.
