Online crime has evolved from attention-seeking individuals into organized criminal enterprises. Researchers have documented the commodification of cybercrime services, with tasks becoming routine, specialized, and systematically managed. Computer scientists evaluating cybercrime have expanded their focus from purely technical analyses to include...

Online crime has evolved from the actions of individual hackers to highly organized criminal enterprises. In this work, we leverage classic organizational theories to better understanding such cybercriminal businesses. We specifically model organizational dimensions such as hierarchy, specialization and interpersonal relationships (authority, ment...

Research on sustainable people management has focused on the macro level, while overlooking methods to implement sustainability at the operational level, specifically, in its employee hiring processes. We argue that when hiring processes assess applicants' sustainability values and behaviors, they determine the degree of values alignment or person-...

This paper focuses on the ADVANCE project, “Advancing the Careers of Women in STEM at Predominantly Undergraduate Institutions (ASAP),” undertaken to support women STEM faculty by understanding and responding to the multi-level effects of gender on their careers in academic science. The goal of the project was to create an environment of formal and...

In this chapter, we develop a framework for understanding how multidimensional, multilevel data is most effectively conveyed in social network diagrams. We build on work begun in 1994, with a series of explorations of social network visualization with the theme of helping viewers make accurate judgments about network properties. In contrast to cont...

This study on informal support networks bridges the traditionally disparate disciplines of personality theory and social network theory, and examines the impact of extroversion on the structure of support networks, as well as the relative contribution of network structure versus extroversion to a critical element of network effectiveness: trust. Tw...

Although top managers must project an image of professionalism and strength, they still require networks of individuals they can trust. The development of trust depends on the degree to which the executives perceive the presence of three critical attributes - ability, benevolence and integrity - within their support networks, and on their ability t...

Within a framework of international strategy for multinational corporations, this chapter examines the important opportunities afforded by taking a more inclusive approach to the foreign subsidiary host country workforce (HCW). It argues that past international management writing and practice, with its expatriate bias, has neglected consideration o...

Scholars have recently argued for flatter, organic organizational structures that enable workers to deal more effectively with dynamic and uncertain environments. In a correlational study of 33 R&D teams, we find that although this network form is associated with more smooth coordination in collocated teams, the opposite is true for geographically...

Purpose The purpose of this article is to examine the nature and influence of entrepreneurs' advice networks on the innovative performance of their companies from both economic and social perspectives. Specifically, it aims to address three research questions: Does information typically flow both ways in advice dyads? How important is trust in thes...

There has been considerable debate about the apparent irrationality of end users in choosing with whom to share information, with much of the discourse crystallized in research on phishing. Designs for security technology in general, anti-spam technology, and anti-phishing technology has been targeted on specific problems with distinct methods of m...

A study of business student advice seeking behavior.

Understanding the overall network structure of organizations can help managers to support change. This article describes three different network theories of change, exploring the underlying assumptions and implications of each model. First, the E-I model predicts that cross-departmental friendship ties will help generate positive response to change...

This field interview study examined patterns and content of advice sharing networks among 20 software executives to provide a clearer understanding of how advice relationships are established, the types of advice that are shared and the role that relationships play in the support of information exchange and diffusion. Most advice relationships were...

In this study, we explore the combined effects of layout and motion on viewers' perceptions of social network data. We ask viewers to interpret the overall network and we ask domain specific questions about managing change within a departmental team to understand how network display influences viewers' overall perception of networks. We find that m...

The spatial arrangement of social network data in graphs can influence viewers' perceptions of structural characteristics such as prominence, bridging and grouping. To study the extent of this effect, we conducted an experiment with 80 graduate students. Each student viewed three of five different spatial arrangements of the same network. We found...

Social network analysis uses techniques from graph theory to analyze the structure of relationships among social actors such as individuals or groups. We investigate the effect of the layout of a social network on the inferences drawn by observers about the number of social groupings evident and the centrality of various actors in the network. We c...
