Several comprehensive reviews are united in drawing the conclusion that the cumulative research evidence on work team diversity is equivocal. Rather than review the extant state of diversity research, in this paper we redirect attention to the context of workplace diversity as a possible explanation for these mixed findings. We discuss how diversity context may be conceptualized, specify various aspects of this context at multiple levels of analysis, and consider how contextual variables can shape the outcomes of work team diversity. We present findings from a literature review (1999–2006) to identify key trends and patterns of results reported in recent research as well as contextual factors that have received attention to date. This paper also considers how the non-significant, positive, negative, and curvilinear effects of diversity reported in studies can be explained by the contextual factors outlined. Implications for future research are also discussed.

Organizational creativity and innovation are inherently complex phenomena, and subject to a myriad of broad contextual and social influences. As the evidence grows for the link between innovation and organizational effectiveness and, ultimately, organizational survival, there is no doubting the need for theoretical and practical advances in our understanding. The complex nature of these constructs, however, requires that such efforts utilize a multi-level lens. This chapter discusses key aspects of creativity and innovation in organizations, including fundamental construct definition issues, which underscore the need for a multi-level perspective. It also reviews extant theoretical perspectives for their contributions to a multi-level understanding, and the research in two key areas of social influence – group factors and leadership – that have received substantial attention in the organizational literature. The review and discussion of these areas reveal not only numerous advances, but also substantial limitations that must be resolved through more complex and comprehensive (i.e., multi-level) approaches. The chapter concludes with several recommendations intended to guide and inform future work in the organizational creativity and innovation field.

Does staffing contribute to organizational effectiveness and sustained competitive advantage, or are many of staffing’s implications merely cross-level fallacies? This article provides a critical examination of staffing research and practice, and proposes a multilevel model of staffing that ties together micro (e.g. personnel selection), meso (e.g. team staffing), and macro (e.g. organizational strategy, Human Resources practices) theory, research, and practice. The model is both integrative and prescriptive, providing a basic organizing structure for examining staffing research within and across levels. The article begins with a review of multilevel theory, followed by a review and critique of the dominant staffing paradigms from a multilevel perspective. It is shown these single level paradigms cannot answer many of the primary questions of interest to staffing specialists. In contrast, the multilevel staffing model not only addresses these limitations, but also prompts a variety of new predictions that oftentimes run counter to prevailing wisdom. Staffing specialists are challenged to show how our science and practice contribute to better functioning organizations.

For the past several decades, the field of global leadership has made noteworthy theoretical and empirical progress. The role of a global follower, however, has not been addressed to date. This chapter focuses on global followers and global followership as vital elements of a global leadership process supporting a traditional followership view that “leadership can only occur if there is followership” (Uhl-Bien, Riggio, Lowe, & Carsten, 2014, p. 83). Two assumptions ground the arguments: global leaders and global followers are engaged in a partnering process of global leadership, and followers and global followers have distinctive characteristics influenced by their specific environments. To explore those assumptions, we start by introducing the followership theory and relevant followership characteristics. Subsequently, we address the role of context in global leader–follower dynamics, extrapolate global followership characteristics from relevant multidisciplinary literature, and offer an example of a global leader–follower partnership. Next, we examine mentions of global followers and global followership in academic and nonacademic literature, and define a global followership construct. The conceptual framework, global followership model, research agenda, and practical implications conclude the manuscript.

Part-time employment is a vital portion of the U.S. labor force, yet research to date has provided only limited insights into how to successfully create and manage this sector of the workforce. We propose that these limitations are due, at least in part, to an inadequate explication of the levels issues inherent in this area. In this article, we present a summary framework of constructs at the economic, industry, organization, individual, and work levels that influence part-time work arrangements. We then specify a cross-level moderator model that examines how the number of hours worked by employees influences their attitudes and behaviors. We posit that this relationship is moderated by a number of contextual effects at multiple levels. Using this sample model, we demonstrate the way in which researchers examining part-time work arrangements can effectively address levels issues. Our article concludes with a discussion of the implications that this summary framework has for researchers, practitioners, and policy makers.

To investigate the nature of investment expertise and factors affecting the information processing and performance of investment experts, this paper hypothesizes normative characteristics of investment expertise and compares such characteristics with actual characteristics documented in prior literature on the investment expert. Based on collective evidence from these sources, a model of investment expertise is proposed.

Results support the existence of investment expertise in (1) the nature of knowledge, (2) problem solving and information search, and (3) performance. A variety of factors that could influence the information processing and performance of the investment expert, including personal, cognitive, and contextual elements, are also discussed in the paper and included in the proposed model of investment expertise.
