Most people participate in various groups and communities simultaneously. Many authors have pointed to the importance of multi‐membership for knowledge sharing across communities and teams. The most important expected benefit is that knowledge that has been acquired in one community of practice (CoP) can be applied into another CoP or group. This paper seeks to discuss the consequences of multi‐membership for knowledge sharing in a CoP.

The concept of multiple inclusion is used to explain why and how multi‐membership can hold up knowledge sharing between groups.

This case study shows that knowledge transfer between CoPs and teams can be problematic when norm sets between these two groups conflict.

This paper concludes that CoPs can sustain when the “practice” remains at a safe distance from the “real” project work in teams that are guided by managerial objectives.

The purpose of this study is to explore polygamous program loyalty in hotel loyalty programs and the relationship between members’ behavioral loyalty and their perceptions of the program effectiveness.

Descriptive statistics, discriminant analysis, ordinary least square regression and one-way ANOVA methods.

This study suggests that the flexibility to purchase points in a loyalty program is significantly associated with the polygamous program loyalty. Members will stay in only one program if they perceive such flexibility. Although members tend to emphasize purchasing accommodation from the loyalty programs’ hotels, they do not necessarily advocate or pay price premiums for the brand. Compared with basic members, elite members exhibit higher levels of loyalty behaviors in general, but not in terms of paying price premiums.

The results suggest that how customers value a loyalty program can differentiate the number of membership(s) they have. Increasing the flexibility of point purchase in hotel loyalty programs encourages customers to stay in only one program. With a majority of the participants in the study being senior travelers, the results and implications should be generalized only in the senior market. A larger and more diverse sample is recommended for future research.

If loyalty programs seek to keep members from joining other loyalty programs, they should increase members’ likelihood to achieve their expected benefits such as increased flexibility of point purchase. In addition, loyalty programs should encourage, recognize and incentivize members’ reciprocal behaviors based on the norm of reciprocity to build a reciprocal chain in loyalty programs. However, in seeking sustained loyal behavior, loyalty programs need to demonstrate value beyond transactional rewards.

This paper explores the reason why customers join multiple loyalty programs (i.e. polygamous program loyalty) and identifies a broken reciprocity link in hotel loyalty programs. Many members primarily focus on the utilities of loyalty programs rather than contributing back to the program; therefore, the norm of reciprocity is suggested to improve loyalty program effectiveness.

Purpose – We explore two characteristics of groups in today's work environments, membership dispersion and geographic dispersion, and the effects that these conditions have on group and organizational learning.

Approach – We integrate findings on group membership dispersion and geographic dispersion and develop predictions of dispersion's effects on group learning, incorporating the literature on knowledge transfer, transactive memory, turnover, and communication.

Findings – Members in multiple work groups, while exposed to knowledge from different areas, have weaker group identities and are more adversely affected by time constraints than members who belong to only one group. Group members can be dispersed sequentially through turnover, which creates more knowledge-retention problems than those experienced by stable groups. Members of geographically dispersed groups are in positions to integrate novel knowledge. The necessary use of technology to communicate, however, reduces the ability of geographically dispersed group members to convey ideas as effectively as their collocated counterparts. Geographically distributed group members experience less common ground and more difficulty in transferring knowledge, especially tacit knowledge, than their collocated counterparts.

Originality/value – We discuss how membership and geographic dispersion pose challenges to and provide opportunities for group learning. We suggest how learning within dispersed groups can be supported as well as what the future holds for the role of these groups in the new economy. The chapter concludes that although membership and geographic dispersion pose challenges to learning at the group level, these conditions enable learning at the level of the organization.

The purpose of this paper is to empirically examine the inequality perpetuated through social categories in accessing the social capital generated through the microfinance interventions in India as the country has pronounced economic inequality by social categories like many developing stratified societies.

The study uses survey data collected from 75 villages in rural India and tests whether the formation and maximization of social capital through self-help groups (SHGs) is dominated by social categories, e.g. high-caste groups, males and superior occupation classes. Using logistic regression framework, the study assesses the formation and maximization of social capital through multiple SHG membership.

The paper finds that the microfinance approach of empowering weaker sections is considerably limited in its success, in the sense that it provides them with the opportunity to the credit access and support through SHGs. But, the empirical model further indicates that social capital in form of these SHGs may fall prey to the dominant social categories, and thus, these institutions may potentially enhance inequality.

The paper is derived from the secondary data set, so it is unable to comment field reality qualitatively.

Microfinance policy makers will have an improved understanding of inherent social inequalities while implementing group-based programs in socially stratified societies.

Social capital, if treated as an outcome accumulated in form of groups, provides with an important framework to assess the unequal access through the microfinance interventions. Overlooking the inherent unequal access will deceive the purpose of social justice in the group-based interventions. The microfinance and other welfare policies engaged in group formation and generating the social capital need to be more sensitive to the disadvantageous sections while focusing on multiple group access by disadvantaged social groups.

Team composition research considers how configurations (e.g., team-level diversity) of team members’ attributes (e.g., personality, values, demographics) influence important outcomes. Our chapter describes key issues in understanding and effectively managing team composition over time.

We discuss how context shapes team composition. We review empirical research that examined relationships between team composition, and team processes and emergent properties over multiple time points. We review research that examined how composition can be effectively managed over the lifecycle of a team.

Context shapes the nature of team composition itself (e.g., dynamic composition). To the extent that membership change, fluid boundaries, and multiple team membership are present should be accounted for in research and practice. The research we reviewed indicated no, or fleeting effects for surface-level (e.g., demographics) composition on the development of team processes and emergent properties over time, although there were exceptions. Conversely, deep-level composition affected team processes and emergent properties early in a team’s lifespan as well as later. Team composition information can be used in staffing; it can also inform how to best leverage training, leadership, rewards, tasks, and technology to promote team effectiveness.

Teams are the building blocks of contemporary organizations. Understanding and effectively managing team composition over time can increase the likelihood of team.

Our chapter provides novel insights into key issues in understanding and effectively managing team composition over time.

This paper aims to explore the dynamics of critical problem-solving (CPS) project teams and creativity throughout a project’s duration, in a multiple-project environment with consideration of the project’s external factors, such as customer situations. In addition, behavioural elements of the CPS project – multiple team memberships, cross-understanding and the transactive memory system – will be investigated in a multiple-project environment.

This paper investigates the dynamics of a CPS project team and creativity in a global software support organisation by conducting semi-structured interviews in Japan and Germany. There were 53 interviewees in Japan and 51 in Germany. The results presented in this paper show the outcomes of a qualitative study, specifically focusing on the processes of CPS projects using thematic analysis. In the discussion section, propositions are given based on this research’s findings as well as existing literature to denote future research possibilities.

The results of this study suggest that creativity to resolve critical problems in a project team occurs by integrating diverse information and knowledge at multi-level organisational units. They suggest that managerial functions are crucial to determining project composition, and appropriate project environments are created by facilitating multiple team memberships at multi-level organisational units.

For the academic domain, the findings have contributed to the fields of project and human resource management, and team management in a multiple-project environment. To practitioners, this study shows the importance of managing multiple projects by considering human behaviour perspectives when solving critical problems.

The purpose of this paper is to assess whether multiple directorships have an influence on earnings management for Australian publicly listed firms. This paper attempts to determine whether boards with multiple directorships are effective monitors and are able to constrain earnings management activities.

The study adopts resource dependency theory on the relationship between multiple directorships and the extent of earnings management. Data analysis is based on publicly listed firms on Australian Stock Exchange utilising SIRCA database with a final pooled sample of 1,815 firm-year observations from 2008 to 2012.

Using different measures of multiple directorships, it is found that firms having board of directors with multiple directorships exhibit lower levels of earnings management. The results validate the applicability of resource dependency theory on the relationship between multiple directorships and the extent of earnings management suggesting that directors with multiple board seats by sharing experiences, skills, information and other resources limit the extent of earnings management by firms. Evidence also suggests that earnings management behaviour is more pronounced in larger firms compared to smaller firms and as predicted, industry audit specialists restrain earnings management activities.

This study introduces methodological enhancements to the literature as it measures the multiple directorships in a number of different ways. Firms may be encouraged to actively seek board members with diverse backgrounds, international exposure/experience and pertinent skill-sets with multiple board memberships. These benefits will assist firms to determine the optimal board composition that will enable it to function effectively.

Empirical studies on the association between multiple directorships and earnings management in Australia are scarce and this paper provides an update of the effect of multiple directorships on earnings quality in Australia.

Recent research finds that producers assigned to multiple categories receive less attention and legitimacy and have lower chances of success and survival. We argue that the effect of category spanning on the reception from the audience depends on the fuzziness of the categories. When a set of categories lacks contrast (have very fuzzy boundaries), spanning them does not cause much additional confusion for the audience, thus the penalties associated with spanning ought to be slight. But, when the contrasts of the categories spanned are high, audience members will have difficulty interpreting the producer, so spanning categories will be devalued more. We study these processes using data from an online-review web site. Results show that audience members devalue organizations that span high-contrast categories more than those that span low-contrast categories. These effects are weaker for more active reviewers.

As of 1982, federal credit unions were allowed to add select employee groups and thus create institutions with multiple-group common bonds. We examine the efficiency of single bond and multiple bond federal-chartered credit unions by using data envelopment analysis (DEA), a non-parametric, linear programming methodology. Results indicate that multiple bond credit unions have better pure technical efficiency than single bond credit unions. However, single bond credit unions appear to be more scale efficient than the multiple bond credit unions. Our results also indicate that members of multiple bond credit unions may derive greater wealth gains than members of single bond credit unions.

The growth of research on the cognitive origins of market performance has focused on the impact of categories as a primary cognitive mechanism by which exchange occurs. In this research, performance outcomes are typically reduced when firms and products fail to meet audiences’ expectations about membership into categories. The ensuing literature has focused on spanning categories as evidence of not meeting audience expectations while largely ignoring the specific study of expectations themselves. This chapter argues that expectations for market behavior are important in their own right, and can impact market outcomes even when categorical boundaries are respected. Using the market for engagement rings as a setting, I show how lack of adherence to expectations can both increase and decrease market value even as the engagement rings adhere to categorical boundaries. Rather than simply focusing on category spanning as evidence that audience expectations have not been met, the findings suggest that expectations should be considered explicitly, with implications for competitive strategy.
