The purpose of this paper is to identify distinguishing term characteristics from among the information of term appearance situations (tas) residing in the relevant/irrelevant documents retrieved for use. Terms with specific characteristics could be used in the distinguishing of user profiles, documents, pages or concepts to assist in information retrieval.

First, a method to apply the potential term characteristics in the distinguishing of user profiles in the information retrieval environment is designed. Then, an information retrieval system is developed to demonstrate the realisation and sustain the study of the method. Formal tests are conducted to examine the distinguishing capability of the potential term characteristics proposed in the method.

The results of the tests show that the potential term characteristics proposed in this study are successfully applied in the distinguishing of user profiles in the information retrieval environment.

Identification of distinguishing term characteristics would expand the ground for the IR community in the design of feature‐extraction algorithms or systems that try to cull information from structured or unstructured documents.

The purpose of this paper is to examine the impact of directors’ and officers’ liability insurance (D&O insurance hereafter) on corporate governance and firm performance, with a specific focus on investment efficiency.

Using a sample of Chinese A-share listed firms from the period 2007 to 2020, this study uses Ordinary Least Squares regressions to investigate the research questions, as well as moderating and mediating effects. Additionally, alternative measures of investment efficiency are used, and the Heckman two-stage model and propensity score matching model are used to demonstrate the consistency of the findings and to mitigate the risk of endogeneity.

The findings of this study suggest that purchasing D&O insurance has a detrimental impact on corporate investment efficiency, particularly in the context of over-investment activities; robust internal governance mechanisms, exemplified by a higher shareholding ratio of the top shareholder and enhanced internal control quality, alleviate this negative effect; and financing constraints act as a mediating factor in the association between D&O insurance and investment efficiency.

Corporate investment efficiency is of significant importance for both national macroeconomic growth and micro-enterprise development. Notably, the prevalence of D&O insurance among Chinese firms is progressively increasing, thus exerting a growing influence. This study contributes to the existing literature on D&O insurance and corporate investment efficiency, providing valuable insights into the economic impact of D&O insurance on Chinese firms. The empirical evidence presented herein facilitates future reforms and adjustments.

The purpose of this paper is to examine the effect of New Rural Pension Scheme (NRPS) on the private transfer behavior of the non-co-resident adult children to their elderly parents in rural China, and hence address the income redistribution effectiveness of public program for the elderly in rural China.

Pooled data from two waves of the China Health and Retirement Longitudinal Study and the combination of regression discontinuity design and difference in difference method are used to perform the analysis.

No evidence is found that pension payment from NRPS program does significantly crowd out the economic support from the adult children to their elder parents. The heterogeneous effects at different income percentile indicate that pension payment significantly increases the probability of receiving gross transfers and likelihood of the net transfer being positive for those elderly individuals with low income; in particular, the distinctive “family binding” arrangement may dramatically contribute to increasing the probability of receiving private transfers for the pension recipients.

The empirical findings would have far-reaching implications for the efficacy of public transfer or re-distributive programs such as NRPS; for the rural elderly, in particular, the unique “family binding” mechanism under the NRPS program may have positive welfare effects on the intended beneficiaries. Furthermore, an understanding of the inter-linkage between informal arrangements of elderly support and social re-distributive program provides further insight into the design of social security systems targeted to the vulnerable group in developing countries.

Leveraging marketer-generated content (MGC) can increase firms' success. However, few studies uncover the effects of MGC-related attributes on consumer engagement in the context of food marketing. This paper aims to explore the influence of MGC characteristics (valence, content types, vividness and interactivity) on consumer engagement.

This study uses WeChat official account data of seven food companies from China and conducts negative binomial regression models.

The findings indicate that different MGC-related characteristics have separate impacts on consumer WeChat engagement. Title valence, transactional title content and title with punctuation vividness negatively affect consumers' consuming engagement. Knowledgeable or entertaining title content and title with interactivity both positively affect consumers' consuming engagement. Moreover, transactional body text content negatively influences consumers' contributing engagement, whereas entertaining body text content shows positive effects. Vivid and interactive MGC body text attributes enhance consumers' contributing engagement behavior.

This study contributes to social media research in food marketplaces and sheds light on the effect of different WeChat MGC characteristics on separate consumer engagement.

The purpose of the paper is to evaluate the essential role of corporate social responsibility (CSR) on SMEs' performance by exploring the mediating role of corporate image (CI), corporate reputation (CR) and customer loyalty (CL) between CSR and firm performance (FP) in the context of an emerging country.

Based on an extended literature review on CSR, CI, CR and CL studies, the authors evaluate the impact of these four constructs on SMEs' performance in an emerging market. The paper follows a quantitative approach. The study sample was composed of 482 responses covering top executives, managers and experts. The Smart PLS SEM version 3.3.2 was used to analyse the data of the small- and medium-sized enterprises (SMEs) of Vietnam in the year 2020–2021.

The authors' findings reveal significant and positive relationships amongst CSR, FP, CSR and CI, CSR and CR, CSR and CL, and most importantly, the findings add value to the current knowledge by exploring the mediating effect of CI, CR and CL between CSR and FP.

The study was conducted in Vietnam. As a result, the findings of the study might not be applicable for other countries, if the economic and environmental settings are different from that of Vietnam. Therefore, future research should consider for other countries, other regions. Second, due to the purpose and priority of the study, CI, CR, and CL was employed as mediators amongst the relationship between CSR and FP. Thus, future research should consider other mediators or moderators in such a relationship to see how CSR generates outcomes in the new associations.

The study regarding the role of CSR in enhancing the performance of SMEs can motivate firm's chief executive officers (CEOs) to be proactive in getting involved and practising CSR in a consistent manner. Second, the above discussion draws a very important implication for the executive level, the management level of the enterprise, which enterprises should balance the interests of business, customers, other stakeholders, the environment and society in order to optimise CSR outcomes for improving competitiveness and developing sustainably. This implication is particularly important to the survival and development of SMEs in a challenging emerging economy.

The study widens the literature regarding relationship between CSR and SMEs' performance. Besides, the study supports stakeholder theory that explains why CSR positively affects firm's performance. The significant mediating roles of CI, CR and CL were positively confirmed in the study. Although previous studies determined that such roles are strategic source of competitive advantages of enterprises, however, how CSR involved in enhancing the roles has not been deeply explored and integrated. Third, the findings of the study support the resource-based view (RBV) and resource-based perspective that explains why firm should engage in CSR activities, and CI, CR and CL can enhance firm's performance by providing strategic source of competitive advantages that facilitate business to improve its performance in sustainable direction.

To the best of the authors' knowledge, the current literature on CSR and FP shows that, to date, there has been little empirical research on the mediating mechanism of CI, CR and CL in the link between CSR and FP for SMEs. The findings of the study may have great implications for entrepreneurs and top management with respect to the strategic perspectives to drive the businesses and to improve firm's performance in a sustainable direction in the context of emerging markets. In addition, the finding might be of great interest to – and motivate – SMEs' managers to engage with CSR actions where such businesses were or are situated during and after the coronavirus disease-2019 (COVID-19) pandemic. By that understanding, the Government might allow for innovative and groundbreaking policies or the reformation of old policies to leverage businesses to promote their strengths towards sustainable development in the new economic settings. The findings of the study may be a significant contribution to SMEs in Vietnam and in other emerging economies.

The purpose of this paper is to investigate the mediating effect of information search effort on the relationship between leader narcissism and team creativity in China based on attention theory. The paper also explores participative decision making as a moderator in the relationship between team leader narcissism and information search effort.

Through a survey of 667 team members and their team leaders from 96 research and development teams at 23 high-tech enterprises in China with paired samples, cross-time data were collected. Confirmatory factor analysis, hierarchical regression and path analysis were adopted to analyze the data.

This paper found that leader narcissism had a positive impact on team information search effort, thereby promoting team creativity, and the effect of leader narcissism on team information search effort is more positive in the context of high participation in decision making.

Narcissism should be a noteworthy trait in manager selection and promotion especially for the departments and teams which focus on innovation and creation. And companies should pay attention to the team work processes to ensure that team members have the opportunity to participate in decision making for promoting the team leader’s narcissistic “bright” side in the institutional environment and avoiding the “dark” side.

This paper discusses how and when leader narcissism influences team creativity in Chinese high-technology enterprises based on attention theory. This research expands the application of attention theory at the team level.

The purpose of this paper is to explore new banks ' market niche position choices at the time of founding.

The authors used data on the establishment of new banking organizations in California, over 1979-1988, to test the hypotheses. During that time, banking within California experienced dramatic deregulation, which provided ample opportunities for new bank start-ups.

New banks were found to enter more often in specialist market niches when the market was highly concentrated, but less often when there were more non-bank financial institutions active in the market. The frequency of new specialist entries displayed an inverted U-shaped pattern as the number of established specialist banks in the market increased.

The findings confirm the idea that elements of market structure influence the niche positioning decisions of new ventures. The paper contributes to our understanding of entrepreneurial decision making in response to environmental conditions.

The empirical findings of the roles of emotions in teams are mixed. This study, a scoping literature review, aims to synthesize extant research on the roles of emotions in work teams and offers future research directions.

Sixty-nine empirical studies from the past ten years (2012 to 2021) were identified and reviewed. The authors then analyzed these 69 papers based on their research design, focus and nomological network of emotions.

The authors found that there is a clear increasing research trend of studying emotions in a team setting. In the extant literature, team emotions were studied from three major perspectives: emotions, emotional management and emotion measurement. The authors also summarized findings into the nomological network of team emotions. Last but not least, future research directions regarding the research context, focus and design and analysis were recommended.

The role of emotions in teams has not been extensively reviewed or synthesized, and the empirical findings are mixed. This paper synthesized the role of emotions in teams and critical factors that affect emotions in teams. In particular, the research recommendations for critical human resource development scholars cover three aspects: research context advancement, research focus advancement and research design and analysis advancement.

The purpose of this paper is to investigate relationships of urban seismic resilience assessment indicators.

To achieve this aim, construction of the urban seismic resilience assessment indicators system was conducted and 20 indicators covering five dimensions, namely building and lifeline infrastructure, environment, society, economy and institution were identified. Following this, this study used evidence fusion theory and intuitionistic fuzzy sets to process the information from experts then developed the fuzzy total interpretive structure model.

A total of 20 urban seismic resilience assessment indicators are reconstructed into a hierarchical and visual system structure including five levels. Indicators in the bottom level including debris flow risk, landslide risk, earthquake experience and demographic characteristics are fundamental indicators that significantly impact other indicators. Indicators in the top level including open space, gas system and public security are direct indicators influenced more by other indicators. Other indicators are in middle levels. Results of MICMAC analysis visually categorize these indicators into independent indicators, linkage indicators, autonomous indicators and dependent indicators according to driving power and dependence.

This paper attempts to explore relationships of urban seismic resilience assessment indicators with the interpretive structural model method. Additionally, Fuzzy total interpretive structure model is developed combined with evidence fusion theory and intuitionistic fuzzy sets, which is the extension of total interpretive structure model. Research results can assist the analytic network process method in assessing urban seismic resilience in future research.

Previous research has shown that diversity is related to both task and relationship conflict in groups. The purpose of this paper is to posit that leadership is an important factor for maintaining high group performance and morale under conditions of conflict. Specifically, the paper argues that leader conflict management, emotion management, and transformational behaviors determine the impact of conflict on group outcomes.

Data were collected from 585 people in 89 workgroups from eight public service organizations in Australia. The authors used hierarchical regression to test the hypotheses regarding group performance and morale. To test mediation and moderation, the authors followed the procedure outlined by Baron and Kenny. Finally, they used the formulas provided by Preacher, Rucker and Hayes to test for moderated mediation.

Results showed that diversity increased task conflict but was unrelated to relationship conflict. Both task and relationship conflict were negatively associated with group performance and morale, and effective leadership reduced these negative effects to zero. There was also a partial support for the authors’ theoretical model predicting that leadership moderates the indirect effect of diversity on group outcomes occurring through the mediator of conflict.

A greater amount of variation in the diversity of work groups included in the sample would have been useful for overcoming problems of restriction of range, which likely reduced ability to observe an association between diversity and group outcomes. Based on the results, in order to prevent negative emotions from task and relationship conflict from damaging group performance, leaders of diverse groups can act to manage those emotions among their group members. Results from this study implicate conflict management training. While training for conflict management is beyond the scope of this research, further research should examine this issue.

The study extends research in the area of diversity, leadership and group work. In particular, it demonstrates that transformational leadership is an important factor for maintaining high group performance and morale under conditions of conflict. It also offers practical assistance to individuals entrusted with the responsibility of managing culturally diverse workgroups.
