Nearly a century ago, Max Weber studied Chinese lineage system and argued that the power of the patriarchal sib impeded the emergence of industrial capitalism in China. Recently, Martin Whyte re-evaluated Weber's thesis on the basis of development studies and argued that, rather than an obstacle, Chinese family pattern and lineage ties may have facilitated the economic growth in China since the 1980s. This paper empirically tests the competing hypotheses by focusing on the relationship between lineage networks and the development of rural enterprises. Analyses of village-level data show that lineage networks, measured by proportion of most common surnames, have large positive effects on the count of entrepreneurs and total workforce size of private enterprises in rural China.

Research and theory on diversity in organizations tends to examine relations between the majority and minority and to overlook relations within the minority. In this chapter we explore the dynamics within a minority that represents a token percentage (less than 15%) of the larger group (Kanter, R. M. 1977b). We argue that members of a minority sub-group are subject to inter-group and intra-group pressures and that these pressures are greatest for a minority of two. We introduce the term “duo-status” to describe this two-token situation and examine the positive, neutral, and negative dynamics that result depending on the coping strategy chosen by each member of the duo.

Understanding the impact of diversity on group process and performance has been the focus of much research, yet there are still unanswered questions about how diversity impacts group process and performance. One factor that is clearly a consequence of group composition is affective tone. In this chapter, we discuss the impact of diversity and homogeneity on affective responses from group members and argue that the relatively negative affective tone experienced in diverse groups may fuel more systematic information processing and improve decision-making performance. The implications for managing both positive and negative affect in groups will be considered.

This chapter explores the role of language in the relationship between diversity and team performance. Specifically, we consider how a linguistic approach to social categorization may be used to study the social psychological mechanisms that underlie diversity effects. Using the results of a study examining the effects of gender, ethnicity and tenure on language abstraction, we consider the potential implications for team processes and effectiveness. In addition, we propose a revised team input-process-output model that highlights the potential effects of language on team processes. We conclude by suggesting directions for future research linking diversity, linguistic categorization, and team effectiveness.

Although some researchers have recognized that context can play an important role in explaining the mixed findings of past diversity research, to date a comprehensive framework for specifying these contextual influences has been lacking. In order to address this gap, we propose a framework for future research that incorporates contextual variables at extra-organizational, organizational, and team levels. We consider how these various aspects of diversity influence categorization-based or elaboration-based diversity outcomes. We also present findings of a literature review that identifies aspects of diversity context that have received attention directly or indirectly in research conducted between 1999 and 2007.

Despite the oft made argument that demographic diversity should enhance creativity, little is known about this relationship. We propose that group diversity, measured in terms of demographic faultlines, affects creativity through its effects on group members’ felt psychological safety to express their diverse ideas and the quality of information sharing that takes place across subgroup boundaries. Further, we propose that the relationship between faultlines and creativity will be moderated by task interdependence and equality of subgroup sizes. Finally, we provide suggestions for how organizations can establish norms for self-verification and use accountability techniques to enhance creativity in diverse groups.

Purpose – To motivate diversity researchers to reconsider prior findings that use homogeneity as the standard to which diverse teams are compared. To recognize that homogeneity may be just as (if not more) influential than diversity in shaping group processes.

Design/approach – We selectively review the diversity literature and develop a conceptual reinterpretation of prior research. We challenge the general orientation in the literature to treat homogeneity as a baseline to which the effects of diversity are compared. We develop propositions that use diversity as the baseline for homogeneity and provide directions for future research.

Findings – We redigest evidence relating to five core areas in which researchers have identified differences between diverse and homogeneous groups, indicating that homogeneity may lead to (1) an avoidance of disagreement, (2) less use of unique information, (3) overconfidence about performance, (4) more social focus, and (5) less sensitivity to relationship conflict than might be warranted. Based on this reinterpretation of prior literature, we propose that homogeneous teams are prone to delusions, assuming they share similar values, opinions, knowledge, and preferences that make their world seem more homogeneous and comfortable than it may actually be.

Originality/value – We attempt to spur greater understanding of how diversity and homogeneity affect group functioning. We stress the independent effects of homogeneity in shaping group outcomes, an underexplored perspective in the diversity literature.

To reap the value in diverse teams, leaders may try to manipulate structural interdependence – through task design – to foster synergistic collaboration. However, ambiguity about the nature and appropriate intersections of members’ unique and valuable cognitive perspectives can make it difficult to fully anticipate collaborative activity in task design. Here, teams need emergent interdependence – members must develop the desire and expectation to work interdependently for the benefit of the work. We therefore present a model of how leaders can promote emergent interdependence for diverse team success, identifying key antecedents and discussing psychological safety as a condition which can enhance their efforts.

In this chapter, we argue that beyond the self-enhancement motive (i.e., the desire for a positive identity), other identity motives play a significant, yet underspecified role in homogeneous and diverse groups. In particular, we explore how the desire for self-verification, belonging, and distinctiveness offer alternative and, at times, even contradictory explanations for findings typically attributed to self-enhancement. We also consider the ways in which these motives are influenced in homogenous and diverse groups and the effects they have on group processes and performance. Through our examination, we aim to stimulate research on the role of multiple identity motives in homogenous and diverse groups.

The sociology of childhood is fraught with problems, not least those centred on the idea, notion or concept of ‘childhood’, and in particular, the issue of how to define, distinguish and identify ‘childhood’ for sociological purposes. The study, analysis and understanding of childhood hinge upon how ‘childhood’ is defined, either explicitly or implicitly, one problem being the plethora of quite diverse approaches in both popular and sociological discourses. While there cannot be a correct definition of ‘childhood’, there can be a best definition, such as for sociological purposes, those of making sense of ‘childhood’ in particular and of social life, relationships and experience in general.
