Is social network analysis just measures and methods with no theory? We attempt to clarify some confusions, address some previous critiques and controversies surrounding the issues of structure, human agency, endogeneity, tie content, network change, and context, and add a few critiques of our own. We use these issues as an opportunity to discuss the fundamental characteristics of network theory and to provide our thoughts on opportunities for future research in social network analysis.

Social networks are not just patterns of interaction and sentiment in the real world; they are also cognitive (re)constructions of social relations, some real, some imagined. Focusing on networks as mental entities, our essay describes a new method that relies on stylized network images to gather quantitative data on how people “see” specific aspects of their social worlds. We discuss the logic of our approach, present several examples of “visual network scales,” discuss some preliminary findings, and identify some of the problems and prospects in this nascent line of work on the phenomenology of social networks.

We argue for a broadened approach to brokerage by distinguishing between brokerage emphasizing a particular structural pattern in which two otherwise disconnected alters are connected through a third party (“brokerage structure”) and the social behavior of third parties (“brokerage process”). We explore a processual view of brokerage by examining three fundamental strategic orientations toward brokerage: conduit, tertius gaudens, and tertius iungens that occur in many different forms and combinations. This processual view is especially relevant in increasingly complex and dynamic environments where brokerage behavior is highly varied, intense, and purposeful, and has theoretical implications for studying multiplexity, heterogeneity, and brokerage intensity.

This paper examines medical managers' beliefs about the impact reduced‐hour career paths for physicians has on organizational effectiveness. The findings of this exploratory inductive study of 17 medical managers at nine medical organizations in the Boston area suggest that managers believe the benefits of reduced‐hour physicians (RHPs) far outweigh the disadvantages. However, many of their reasons appear to be exploitative of RHPs. In particular, managers believe that employing RHPs results in increased managerial control and that RHPs should: work more than they are compensated for; do a disproportionate share of the undesirable work; and remain extra flexible and available to the organization. An interpretation of the findings based on psychological contract theory is offered, and may help to illuminate other results reported in the literature, including some controversial findings that reduced‐hour workers tend to have poor health outcomes.

The purpose of this paper is to reveal those attributes of owners and managers that influence knowledge flows between owners and managers in a tourism destination network. The research question relates to whether homogeneity and/or heterogeneity attributes of the owners and managers are associated with the flow of information within a knowledge network.

Owners and managers of tourism and hospitality businesses in the Bournemouth, Poole and Christchurch conurbation were surveyed regarding their receipt of information from each other. Social network analysis (SNA) was applied to understand how job position, type of business, gender and education attributes influence the information flows within a knowledge network.

It was revealed that the ties or flows of information were influenced through the heterogeneity of the type of education attribute of a business owner or manager. Other attributes such as type of business, job position or gender were not associated with the receipt of information.

The contribution of the paper relates to increasing the understanding of an underlying attribute that influences information flows between owners and managers of tourism and hospitality businesses within a tourism destination.

The paper contributes to the understanding of a heterogeneous attribute that influences the flow of information within a tourism destination network.
