This paper aims to the identification of journal articles that probably report on interdisciplinary research at Wageningen University & Research (WUR).

For identification of interdisciplinary research, an analysis is performed on journals from which articles have been cited in articles (co-)authored by WUR staff. The journals with cited articles are inventoried from the reference lists of the WUR articles. For each WUR article, a mean dissimilarity is calculated between the journal in which it has been published and the journals inventoried from the reference lists. Dissimilarities are derived from a large matrix with similarity values between journals, calculated from co-occurrence of these journals in the WUR articles’ reference lists.

For 21,191 WUR articles published between 2006 and 2015 in 2,535 journals mean dissimilarities have been calculated. The analysis shows that WUR articles with high mean dissimilarities often are published in multidisciplinary journals. Also, WUR articles with high mean dissimilarities are found in non-multidisciplinary (research field-specific) journals. For these articles (with high mean dissimilarities), this paper shows that citations are often made to more various research fields than for articles with lower mean dissimilarities.

Identification of articles reporting on interdisciplinary research may be important to WUR policy for strategic purposes or for the evaluation of researchers or groups. Also, this analysis enables to identify journals with high mean dissimilarities (due to WUR articles citing more various research fields). Identification of these journals with a more interdisciplinary scope can be important for collection management by the library.

This paper seeks to propose and empirically validate a conceptual model on the antecedents of review helpfulness comprising three constructs, namely, valence dissimilarity, lexical dissimilarity and review order.

A panel dataset of customer reviews was collected from Amazon. Using deep learning and text processing techniques, 650,995 reviews on 13,612 products from 570,870 reviewers were analyzed. Using negative binomial regression, four hypotheses were tested.

The results indicate that new reviews with high valence dissimilarity and lexical dissimilarity compared to existing reviews are less helpful. However, over the sequence of reviews, the negative effect of review dissimilarity on review helpfulness can be moderated. This moderation differs for valence and lexical dissimilarity.

This study explains review dissimilarity in the context of online review helpfulness. It draws on the elaboration likelihood model and explains how the impacts of peripheral and central cues are moderated over the sequence of reviews.

The findings of this study provide benefits to online retailers planning to implement online reviews to improve user experience.

This paper highlights the importance of review dissimilarity in identifying user perception of online review helpfulness and understanding the dynamics of this perception over the sequence of reviews, which can lead to improved marketing strategies.

Drawing from moral exclusion theory, this study aims to examine a moderated mediation model for the relationship between perceived overqualification (POQ) and knowledge-hiding behavior directly and via perceived dissimilarity.

Using the convenience-sampling technique, time-lagged (three waves) data were gathered from 595 employees working in different hotels and event management firms. Hayes’ PROCESS macro was used to test the moderated mediation model.

Results showed that perceived dissimilarity among coworkers mediated the result of POQ on knowledge-hiding behavior. In addition, interpersonal disliking moderated the indirect effect in a way that this effect was strong when interpersonal liking was low.

Findings suggest that organizations should make the overqualified realize that they can also learn from their coworkers whom they perceive as less qualified. In this, the feelings of dissimilarity and disliking can be minimized that in turn may decrease the intention to hide knowledge.

The present study offers a new perspective for identifying the nexus between POQ and knowledge-hiding behavior by drawing upon moral exclusion theory and examining the mediating role of perceived deep-level dissimilarity.

The purpose of this study is to understand the conditions in which subordinates, after making a mistake, are more likely to engage in feedback avoidance behaviour (FAB), a set of behaviours that could ultimately jeopardise patient safety in a health care context.

This study used a sample of 183 independent leader-subordinate dyads in the health care service sector. For this study, a multiple mediator model in which three types of conflict (task conflict, relationship conflict and process conflict) were tested and acted as mediating mechanisms that transmitted the effects of perceived dissimilarity to FAB.

The results supported the mediating role of two of the three forms of conflict and highlighted the consequences of dissimilarity between supervisors and subordinates in the healthcare setting.

One of the noteworthy limitations of this study was that this study used cross-sectional time-lagged data. Future research should use a more rigorous longitudinal approach such as a cross-lagged design (Whitman et al., 2012) to explore the dynamic nature of dyadic relationships over time.

An important implication of our study results suggests that health care leadership development training should provide opportunities to increase awareness of the tendency of leaders to treat subordinates perceived as dissimilar more negatively.

These results contribute to our understanding of the interpersonal processes between subordinates and their supervisors, which could have a significant impact on organisational outcomes in the health care setting.

The increasing social media use has been widely recognized for its adverse effects, such as social media fatigue. With the continuously increasing friends on social media, the dissimilarity of individuals in terms of age, personality, and values has increased. It is unclear whether perceived dissimilarity with others is associated with social media fatigue. The authors attempted to bridge this gap by constructing a “perception–emotion–behavioral” research framework. This study investigated the influence of individual perceived dissimilarity on social media fatigue. The authors further investigated the mechanisms mediating the three dimensions of social anxiety in the model.

This study examined the mechanisms by which individual perceived dissimilarity influences social media fatigue, particularly using WeChat application. A field survey study conducted in China with 408 subjects of WeChat app users was used in this study to analyze the study model.

The obtained results demonstrate that individual perceived dissimilarity has a significant positive effect contributing to social media fatigue, perceived dissimilarity is positively correlated to social anxiety. Social anxiety positively affects social media fatigue, and social anxiety partially mediates the positive effect between perceived dissimilarity and social media fatigue.

First, the study confirmed the influence of perceived dissimilarity on social media fatigue, which may enrich the antecedent mechanisms of social media fatigue. Second, the authors demonstrated the social anxiety-mediated development of fatigue. The findings provide an in-depth understanding of users' fatigue. Third, the findings of this study provide valuable insights for preventing of social media fatigue.

The paper aims to clarify the multivariate effects of follower communication apprehension (CA) and demographic dissimilarity on follower perceptions of the leader–follower relationship quality (i.e. measured by leader–member exchange (LMX) theory). This study examined the possible mediating effects of follower CA on the relationship between demographic dissimilarity and LMX.

Research was collected from self-report ratings of one member of the dyad; several proactive techniques were utilized to reduce common method variance in the development and administration of the survey instrument. In total, 260 (N = 260) full-time hospitality industry employees participated in the study.

The results of this study indicate demographic dissimilarity has minimal effect on LMX and CA. However, the results indicated that follower CA was negatively related to follower perceptions of LMX quality. In addition, the results indicated that tenure working with the supervisor was negatively related to follower CA and positively related to follower perceptions of LMX quality.

Research results may lack generalizability, and causality cannot be confirmed. Future studies utilizing longitudinal designs and/or data collected from each member of the dyad may provide support for current findings.

This paper includes implications for understanding how situational characteristics influence follower CA and perceptions of LMX to encourage supervisors to increase communication with new subordinates, especially during the organizational acculturation process, thus reducing turnover. Furthermore, the significant relationship between age dissimilarity and CA offers practical implications for managing and celebrating generational differences in the workplace and bridging the gap between generations by maximizing communication between supervisors and subordinates. Communication is an essential consideration in the hospitality industry linked to creativity, relationship building and enhanced service experiences. Ultimately, this paper provides guidance for leaders to build sustainable, positive relationships with subordinates through more effective communication and build more inclusive service-based organizations.

This paper contributes to communication and leadership management practices by addressing four major problems: (1) limited research on situational characteristics that inhibit LMX quality, (2) limited research on communication variables as antecedents to LMX, (3) minimal research on the relationship between CA and LMX and (4) non-existent research on CA as a mediating variable in the relationship between demographic dissimilarity and LMX.

The purpose of this paper is to explore how perceived visible, work value, and informational dissimilarity affect an individual's helping behavior. Additionally, it investigates the moderating roles of the need for affiliation and need for achievement.

A theoretical analysis was performed.

It is proposed that perceived visible, work value, and informational dissimilarity will have a negative impact on an individual's helping behavior. Additionally, it is posited that the need for affiliation and need for achievement will positively moderate the negative relationship between perceived dissimilarity and helping behavior.

This paper provides additional insight into antecedents of helping behavior, and offers a theoretical basis for future research that examines the relationship between subjective diversity and discretionary behaviors in organizations.

This paper has several important implications. First, managers are recommended to implement effective educational approaches, such as role-playing, that help eliminate employees’ negative perceptions of dissimilarity and promote willingness to help co-workers. Second, managers should reinforce shared vision, values, and goals, which in turn may encourage interpersonal cooperative behaviors. Third, managers should facilitate the dissemination of knowledge and information that are crucial to individual performance. Fourth, managers are encouraged to provide employees with trainings on effective interpersonal processes such as inclusion and emotional management. Finally, managers should increase the degree of task interdependence, which may promote high levels of helping behavior.

This paper is one of the very few studies that link helping behavior with subjective perceptions of dissimilarity. More importantly, this paper highlights the importance of the interaction between dissimilarity perceptions and internal driving forces.

The purpose of this paper is to investigate the relationship between chair–chief executive officer (CEO) demographic dissimilarities and firm internationalization.

The pooled ordinary least squares regression is used on a sample of listed firms in Malaysia from 2013 to 2017. This study considers three demographic dissimilarities between the chair and CEO, i.e. differences in age, educational background and nationality.

The results reveal that demographic dissimilarities between the chair and CEO, notably differences in nationality, may result in conflicting cognitive styles, which in turn may impede the firms’ ability to expand internationally, as compared to differences in age and educational background. The findings demonstrate the deleterious effects of demographic dissimilarity between these two individuals in the highest echelons on the firms’ internationalization strategy due to poor communication and lack of ability to cooperate when dissatisfaction and conflicts intensify between these corporate elites.

To the best of the author’s knowledge, this paper makes the first attempt to examine the influence of chair–CEO demographic dissimilarities on firm internationalization. Previous studies examining firms’ internationalization strategy, for the most part, restricted their scope to either the board members or top management team characteristics, but had largely overlooked the nexus between nonexecutive and executive directors through the chair and CEO. A focus on the demographic dissimilarities between the co-leaders of the firm is essential to improve the understanding of the collaboration and rivalry between them, which may affect board effectiveness and firm internationalization.

Drawing from theoretical perspectives on social identity, self-categorization, intelligence and leader–member exchange, the purpose of this paper is to develop and test a moderated-moderation model involving a member’s task performance in global virtual team.

A survey study was conducted involving both team members and their respective team leaders in global virtual teams (GVTs) in a multinational firm based in the Philippines.

Results demonstrate that a member’s perceived cultural dissimilarity is significantly but negatively related to his or her task performance (as rated by the team leader). Also, results show that a team member’s cultural intelligence (CQ) (as rated by the team leader) exerts a moderating influence in the relationship between perceived cultural dissimilarity and task performance. Lastly, team leader’s CQ (as rated by the team member) exerts a moderating influence on the relationship between perceived cultural dissimilarity and team member’s CQ which consequently impacts a team member’s task performance.

This study contributes to the literature particularly adding to the growing body of literature that identifies factors contributing to the effectiveness of GVTs. Specifically, the authors highlight the critical role of CQ of both team member and team leader in reducing the negative influence of perceived cultural dissimilarity on individual task performance. This study also offers practical recommendations on how to effectively develop and enhance CQ in GVTs so that high levels of effectiveness particularly when delivering the tasks are ensured.

Relying on relational demography and person-organization fit perspectives, the purpose of this paper is to explore the interactive effect of demographic dissimilarity and value congruence on workplace attachment outcomes – affective and normative organizational commitment and turnover intentions. Based on optimal distinctiveness theory, asymmetrical effects across gender and race/ethnicity are also examined.

A diverse sample of 278 restaurant workers in 30 different work units is used to test the hypotheses using hierarchical OLS regression.

The results partially support the idea that perceived and objective value congruence moderate the relationship of race/ethnic and gender dissimilarity on workplace attachment. Tests for asymmetrical demographic group effects showed that value congruence had a stronger moderating effect for whites than for people of color, and for men than for women.

The results suggest that value congruence can ameliorate the adverse diversity effects on workplace attachment, but that a complete substitution effect may not be present. Women and minorities may still be sensitive to demographic representation even when their value congruence is high. This implies that a simultaneous pursuit of fit and diversity is an adequate diversity management strategy to stimulate the inclusion and workplace attachment of all social groups.

This study joins a limited number of studies addressing the interaction of value congruence and demographic dissimilarity, and presents empirical evidence from a work setting. Also, this is the first study to show gender and race/ethnic differences in this interaction.
