Purpose – Criminal groups have long been central to explanations of crime and deviance. Yet, challenges in measuring their dynamic and transient nature meant that group-level explanations were often displaced in favor of individual-level ones. This chapter outlines how network methods provide a powerful tool for modeling the dynamic nature of criminal groups.

Approach – The chapter starts by providing a brief introduction to social network analysis, including key concepts and terminology. The chapter then focuses on the types of relational data available to study criminal groups, and how network methods can be used to delineate group boundaries. The chapter concludes by presenting a framework for understanding group dynamics from a network perspective, describing the contributions of network analysis to theories of group processes.

Findings – Network methods have provided meaningful advances to the study of group dynamics, leading scholars to revisit assumptions about the impact of group’ structure on delinquent behavior. Network studies of group dynamics have primarily focused on the cohesion–delinquency link (within-group structure) and the social contagion of conflict (between-group structure), highlighting important opportunities for the intersection of these two inquiries.

Value – Network methods provide a means to revisit and extend theories of crime and delinquency with a focus on social structure. The unique affinity between group dynamics and network methods highlights immense opportunities for expanding the knowledge of collective trajectories.

The phenomenon of the ethnically homogeneous middleman group (EHMG) or ethnic trade network – the Chinese merchants in Southeast Asia, the Gujarati-Indians merchants in East Africa, the Jewish merchants in medieval Europe, etc. – is ubiquitous in stateless societies, pre-industrial and in less-developed economies (Curtin, 1984). Neoclassical (Walrasian) theory of exchange cannot explain the existence of merchants let alone the phenomenon of the EHMG. This is because Neoclassical theory of exchange is a static theory of frictionless, perfectly competitive markets with the Walrasian auctioneer costlessly coordinating the plans of anonymous producers (sellers) and consumers (buyers) so as to achieve equilibrium. There is no role for merchants in the Neoclassical theory of exchange.

The study of the family firm has gained increased attention in recent years, judging by the number of articles and books published lately as well as the fact that a number of universities in the United States and elsewhere now emphasize a focused study of family business in higher education (Fletcher, 2002; Hoy & Verser, 1994; Litz, 1997). At the same time, the field of entrepreneurship has been enriched by perspectives from sociology and anthropology and has welcomed the study of ethnic business groups, especially in terms of their unique entrepreneurial tendencies as well as their organization and operations within a social order in which they remain a distinct minority (Aldrich & Waldinger, 1990; Light & Gold, 2000).

In today's knowledge-based economy, the ability to produce highly novel and practical ideas is critical to an organization's survival. This paper draws upon social perspectives of creativity (Perry-Smith & Shalley, 2003) and the vital role of recombinant information in creative development (Barron & Harrington, 1981; Hargadon, 2003) to explore information exchange probabilities; exchanges among group members who are deep-level similar fosters incremental creative potential while information exchanges among group members who are deep-level dissimilar fosters radical creative potential. The dynamics of attraction suggest group members are most likely to interact with people who are least likely to facilitate radical creativity. Using a computer simulation we examine how proximity may be used to facilitate information exchanges among deep-level diverse group members to increase the potential for radical creativity. Results suggest the use of proximity to create strong ties among deep-level dissimilar group members may facilitate radical creativity in groups.

Prior reports on theory and research focusing on describing and explaining national cultural influences on purchase and consumption behavior use a net effects approach (i.e., theory and analysis relying on main and interaction effects via statistical analysis). Theory and research in this chapter advances qualitative comparative analysis (QCA) of a configuration perspective of culture's consequences on consumption behavior. This research informs the view that national cultures represent causal recipes (conjunctions) of cultural values; the study of main and interaction effects offer meager representations of national culture's consequences in comparison to adopting a cultural configuration stance. The configuration research here includes transforming Hofstede's country cultural scores into fuzzy set values and applying Boolean algebra to estimate the relevancy of alternative cultural configurations for each of 14 nations to consuming experiences during visits to Australia. The findings support primary and additional hypotheses that specific cultural configurations are sufficient (but not necessary) for describing substantial culture's consequences on consuming tourism experiences. For example, the animus (i.e., Carl Jung's unconscious masculine personality-force) configuration — the combination of high power (P), high individualism (I), high masculine (M), and low uncertainty avoidance (∼U) (i.e., P·I·M·∼U) — is sufficient in indicating not-shopping-for-gifts while visiting Australia. Western national cultures (e.g., United States) have higher fuzzy set scores than Eastern national cultures (e.g., Japan) for the animus configuration.

This article takes stock of interdisciplinary research on Multinational Corporations (MNCs) by elucidating paradigmatic shifts in the world of MNCs in the new millennium and analysing more recent developments in the disciplines of International Business (IB) and Organization Theory (OT). The article also introduces the altogether 14 individual contributions of this 49th volume of the Research in the Sociology of Organizations series. It closes by looking into the questions of where interdisciplinary OT/IB research on MNCs is now and where it is likely to go in the future.
