Why and when do people hide knowledge?
Purpose - 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.

Organic superstructure microwires with hierarchical spatial organisation
Rationally designing and precisely constructing the dimensions, configurations and compositions of organic nanomaterials are key issues in material chemistry. Nevertheless, the precise synthesis of organic heterostructure nanomaterials remains challenging owing to the difficulty of manipulating the homogeneous/heterogeneous-nucleation process and the complex epitaxial relationships of combinations of dissimilar materials. Herein, we propose a hierarchical epitaxial-growth approach with the combination of longitudinal and horizontal epitaxial-growth modes for the design and synthesis of a variety of organic superstructure microwires with accurate spatial organisation by regulating the heterogeneous-nucleation crystallisation process. The lattice-matched longitudinal and horizontal epitaxial-growth modes are separately employed to construct the primary organic core/shell and segmented heterostructure microwires. Significantly, these primary organic core/shell and segmented microwires are further applied to construct the core/shell-segmented and segmented-core/shell type’s organic superstructure microwires through the implementation of multiple spatial epitaxial-growth modes. This strategy can be generalised to all organic microwires with tailored multiple substructures, which affords an avenue to manipulate their physical/chemical features for various applications.
Rationally designing and precisely constructing the dimensions, configurations and compositions of organic micro- and nanomaterials are key issues in material chemistry, but remain challenging. Here, the authors realize the fine synthesis of organic superstructure microwires via a hierarchical epitaxial-growth approach.

How and When Does Leader Behavioral Integrity Influence Employee Voice? The Roles of Team Independence Climate and Corporate Ethical Values
Management literature has repeatedly shown that an absence of voice can have serious negative influences on team and organization performance. However, employees often withhold suggestions or advices when they have ideas, concerns, or opinions. The present study proposes leader behavioral integrity as a key antecedent of employee voice, and investigates how and when leader behavioral integrity influences employee voice. Specifically, we argue that leader behavioral integrity affects employee voice via team independence climate. In addition, we propose a moderating effect of corporate ethical values. The results from a study of 134 managers and 408 employees provide support for this moderated mediation model. Leader behavioral integrity positively affects employee voice via team independence climate, but only when ethical values are emphasized in organizations. These results suggest that leader behavioral integrity, along with team independence climate and corporate ethical values, is very important for fostering employee voice.

Job- and organization-based psychological ownership: relationship and outcomes
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.

Implied threats of the Red Sea crisis to global maritime transport: amplified carbon emissions and possible carbon pricing dysfunction
Recent military acts in the Red Sea and Gulf of Aden are forcing merchant ships to reroute, thereby driving up international shipping rates, prolonging delivery dates, and causing additional greenhouse gas emissions. Utilizing the European Union (EU) Monitoring, Reporting, and Verification emissions database and real time Automatic Identification System data, this study conducted frequency analysis and causative investigation on container ships circumnavigating the Cape of Good Hope. The findings indicate that the current policy framework under the EU Emissions Trading System (EU-ETS) poses a higher risk of carbon leakage, particularly for medium and small-sized container ships, thereby undermining the effectiveness of the nascent EU maritime carbon pricing. If the crisis continues, combined with anticipated tighter emission regulations, this risk is expected to escalate. International maritime policy administrators should make timely adjustments in response to the chain reactions caused by war, enhancing the robustness of cross-regional carbon pricing.

Remote light-controlled intracellular target recognition by photochromic fluorescent glycoprobes
Development of powerful fluorescence imaging probes and techniques sets the basis for the spatiotemporal tracking of cells at different physiological and pathological stages. While current imaging approaches rely on passive probe–analyte interactions, here we develop photochromic fluorescent glycoprobes capable of remote light-controlled intracellular target recognition. Conjugation between a fluorophore and spiropyran produces the photochromic probe, which is subsequently equipped with a glycoligand “antenna” to actively localize a target cell expressing a selective receptor. We demonstrate that the amphiphilic glycoprobes that form micelles in water can selectively enter the target cell to operate photochromic cycling as controlled by alternate UV/Vis irradiations. We further show that remote light conversion of the photochromic probe from one isomeric state to the other activates its reactivity toward a target intracellular analyte, producing locked fluorescence that is no longer photoisomerizable. We envision that this research may spur the use of photochromism for the development of bioimaging probes.
Fluorescence sensing in biological environments is prone to background signal interference. Here the authors design a photochromic fluorescent glycoprobe for light-controlled photo-switchable cell imaging and photo-activated target recognition, resulting in an increased sensing precision.

How and when intragroup relationship conflict leads to knowledge hiding: the roles of envy and trait competitiveness
Purpose
Although studies have demonstrated that knowledge hiding is an important inhibitor of organizational innovation, current research does not clearly address how intragroup relationship conflict influences knowledge hiding. This study aims to identify the underlying mechanism between intra-group relationship conflict and knowledge hiding.
Design/methodology/approach
Drawing on affective events theory (AET), the authors propose a theoretical model and empirically test it by applying hierarchical regression analysis and a bootstrapping approach to data from a multi-wave survey of 224 employees in China.
Findings
Consistent with AET, the empirical results show that envy mediates perceived intragroup relationship conflict and knowledge hiding. As predicted, trait competitiveness moderates the indirect effect of perceived intragroup relationship conflict on knowledge hiding via envy.
Originality/value
The results support an AET perspective whereby knowledge hiding is shaped by relationship conflict, envy and trait competitiveness. This study introduces the novel proposition that relationship conflict and competitiveness influence envy, and consequently knowledge hiding.

Probing Krylov complexity in scalar field theory with general temperatures
A
bstract
Krylov complexity characterizes the operator growth in the quantum many-body systems or quantum field theories. The existing literatures have studied the Krylov complexity in the low temperature limit in the quantum field theories. In this paper, we extend and systematically study the Krylov complexity and Krylov entropy in a scalar field theory with general temperatures. To this end, we propose a new method to calculate the Wightman power spectrum which allows us to compute the Lanczos coefficients and subsequently to study the Krylov complexity (entropy) in general temperatures. We find that the Lanczos coefficients and Krylov complexity (entropy) in the high temperature limit will behave somewhat differently from those studies in the low temperature limit. We give an explanation of why the Krylov complexity does not oscillate in the high-temperature region. Moreover, we uncover the transition temperature that separates the oscillating and monotonic increasing behavior of Krylov complexity.
