PurposeThe purpose of this paper is to investigate gender differences in the formation of mental models of firm strategies.Design/methodology/approachThe specific research question is how gender, social interaction, team psychological safety and synergistic knowledge development influence certain characteristics – complexity and centrality – of an individual's mental model of firm strategies. A survey was conducted on a sample of US business students enrolled in strategic management courses. Social interaction, team psychological safety and synergistic knowledge development were measured by use of multiple‐item seven‐point Likert scales. Mental models were constructed by the causal mapping method. Hierarchical regression analyses were used to test the hypotheses.FindingsThe regression analyses of the survey data support most of the hypotheses. Gender directly influences complexity and centrality in mental models of firm strategies and moderates the predictive influence of social interaction on synergistic knowledge development.Research limitations/implicationsPossible limitations are the use of a student sample and of respondents as the sole data source. Future research could use managers as research subjects and multiple data sources and explore other determinants of the mental model of firm strategies.Practical implicationsThe findings alert university educators about the importance of helping women develop high‐order knowledge and problem‐solving skills by understanding various business functions and synthesizing diverse perspectives. Corporate managers need to design and implement special mentoring and training programs for women with the aim of enriching their specific management knowledge. This study also suggests that women may increase their chance of developing strategic knowledge by proactively networking with senior managers.Originality/valueThis study on gender differences in accumulating management knowledge and skills helps us better understand the roots of and solutions to the gender gap in management and leadership positions. The most intriguing result is the demonstration of gender differences in the development of specific management knowledge. Biases against women not only contribute directly to the "glass ceiling"; more disturbingly, they negatively influence women's internal development of knowledge structures.

Abstract
The lexicon is an evolving symbolic system that expresses an unbounded set of emerging meanings with a limited vocabulary. As a result, words often extend to new meanings. Decades of research have suggested that word meaning extension is non-arbitrary, and recent work formalizes this process as cognitive models of semantic chaining whereby emerging meanings link to existing ones that are semantically close. Existing approaches have typically focused on a dichotomous formulation of chaining, couched in the exemplar or prototype theories of categorization. However, these accounts yield either memory-intensive or simplistic representations of meaning, while evidence for them is mixed. We propose a unified probabilistic framework, infinite mixture chaining, that derives different forms of chaining through the lens of cognitive efficiency. This framework subsumes the existing chaining models as a trade-off between representational accuracy and memory complexity, and it contributes a flexible class of models that supports the dynamic construction of word meaning by automatically forming semantic clusters informed by existing and novel usages. We demonstrate the effectiveness of this framework in reconstructing the historical development of the lexicon across multiple word classes and in different languages, and we also show that it correlates with human judgment of semantic change. Our study offers an efficiency-based view on the cognitive mechanisms of word meaning extension in the evolution of the lexicon.

This study discussed the construction of a digital sharing platform in the field of supply chain management (SCM) and its multi-dimensional and far-reaching impact on performance. With the rapid development of global economic integration and information technology, enterprise SCM is facing unprecedented complexity and challenges. As an innovative solution, the digital sharing platform reshapes the operation mode of the supply chain (SC) and greatly improves efficiency, enhances collaboration, and lays a solid foundation for enterprises to maintain an advantageous position in the fierce market competition. This study defined the concept of a digital sharing platform, expounded its core functions in detail, and analyzed the specific mechanism of the platform in promoting seamless information sharing, optimizing resource allocation, reducing operating costs, accelerating response speed, and improving supplier satisfaction. Through theoretical discussion and empirical analysis, this study concludes that the digital sharing platform is the key driving force to improve the overall performance of the SC and has great strategic significance for sustainable development.

AbstractFacing the growing problem of carbon emission pollution, the scientific and reasonable division of environmental management power between governments is the premise and institutional foundation for realizing China's carbon emission reduction target in 2030. In this article, we directly assess the degree of environmental decentralization according to the allocation of environmental managers among different levels of government. By incorporating fiscal decentralization indicators, the provincial panel data and dynamic spatial econometric model are used to empirically test the impact of environmental decentralization on carbon emissions from a spatial perspective. The results show that (1) China's provincial carbon emissions have significant inertia dependence and spatial path dependence. The increase (decrease) of provincial carbon emissions will lead to the increase (decrease) of carbon emissions in neighboring regions. (2) At the national level, environmental decentralization, environmental administrative decentralization, and environmental monitoring decentralization significantly reduce China's carbon emissions, while environmental supervision decentralization and fiscal decentralization significantly increase carbon emissions. Similarly, the interaction of environmental decentralization and its decomposition indicators and fiscal decentralization also significantly promotes carbon emissions, and the impact is related to the types of environmental management decentralization. (3) The carbon emission effects of environmental decentralization in different regions are heterogeneous. The inhibition effect of environmental decentralization, environmental administrative decentralization, and environmental monitoring decentralization on carbon emissions in the western region is significantly greater than that in the eastern and central regions, but the inhibitory effect of the interaction of environmental decentralization and its decomposition index and fiscal decentralization on carbon emissions in the eastern region was significantly stronger than that in the central and western regions. The above results provide theoretical support for China to construct a differentiated carbon emission environmental management system from two aspects of regional differences and environmental management power categories.

PurposeThis study identifies an effective communication strategy for promoting restaurants' green efforts to customers by using different types of green advertisement messages. This study aims to investigate the relative persuasiveness of attribute-based versus benefit-based appeal messages in green restaurant advertisements and their matching effect with different types of green practices in the restaurant (environment-focused green practices vs food-focused green practices) and with different types of restaurants (fine dining vs fast casual dining) on customers' attitude and visiting intention toward green restaurants. Furthermore, the study examines a moderating effect of restaurant types to assess whether the matching effects between types of messages and types of green practices work differently within the different types of restaurants.Design/methodology/approachA 2 (attribute-based vs benefit-based messages) × 2 (food-focused vs environment-focused green practices) × 2 (fast casual vs fine dining restaurants) between-subject experimental design was used to test the proposed hypotheses. An online scenario-based survey was developed and distributed to online panel members in the USA. Ultimately, 363 responses were used for data analyses. ANOVA and t-test were conducted to analyze the data.FindingsThe results indicate that benefit-based messages are generally more persuasive than attribute-based messages in green restaurant advertisements. For restaurants with food-focused green practices, an advertising message emphasizing the benefit of food-focused green practices (benefit-based message) would be more effective than an advertising message describing their tangible efforts to show the greenness of the restaurant (attribute-based message). For fine dining restaurants, a green advertisement with benefit-based information would be more persuasive than attribute-based information. This study further showed that the aforementioned interaction effect between types of green practices and types of messages was salient for fine dining restaurants.Originality/valueThis research is one of the few studies in restaurant management to examine the green communication effectiveness in terms of the types of green practices and the types of advertising message framing. By comparing the relative persuasiveness of green advertisements on consumers' attitudes and behavior intentions, this study provides suggestions for restaurant professionals to make effective green communication strategies based on the type of green practices the restaurant primarily uses and the type of restaurant the manager is operating.
