Expanding research on corporate corruption, management and organizations

In this special issue introduction, we briefly describe a variety of research paths researchers have followed to study the multifaceted phenomenon of corruption. Furthermore, we classify the papers included in this special issue according to their contribution to these research paths and briefly preview them. Finally, drawing on these four research paths and the papers included in this special issue, we propose a six-item agenda for future research on corruption

Traffic flow densities in large transport networks

We consider transport networks with nodes scattered at random in a large domain. At certain local rates, the nodes generate traffic flowing according to some navigation scheme in a given direction. In the thermodynamic limit of a growing domain, we present an asymptotic formula expressing the local traffic flow density at any given location in the domain in terms of three fundamental characteristics of the underlying network: the spatial intensity of the nodes together with their traffic generation rates, and of the links induced by the navigation. This formula holds for a general class of navigations satisfying a link-density and a sub-ballisticity condition. As a specific example, we verify these conditions for navigations arising from a directed spanning tree on a Poisson point process with inhomogeneous intensity function.Comment: 20 pages, 7 figure

Large deviations in relay-augmented wireless networks

We analyze a model of relay-augmented cellular wireless networks. The network users, who move according to a general mobility model based on a Poisson point process of continuous trajectories in a bounded domain, try to communicate with a base station located at the origin. Messages can be sent either directly or indirectly by relaying over a second user. We show that in a scenario of an increasing number of users, the probability that an atypically high number of users experiences bad quality of service over a certain amount of time, decays at an exponential speed. This speed is characterized via a constrained entropy minimization problem. Further, we provide simulation results indicating that solutions of this problem are potentially non-unique due to symmetry breaking. Also two general sources for bad quality of service can be detected, which we refer to as isolation and screening.Comment: 28 pages, 5 figures; corrected several misprint

Large-deviation principles for connectable receivers in wireless networks

We study large-deviation principles for a model of wireless networks consisting of Poisson point processes of transmitters and receivers, respectively. To each transmitter we associate a family of connectable receivers whose signal-to-interference-and-noise ratio is larger than a certain connectivity threshold. First, we show a large-deviation principle for the empirical measure of connectable receivers associated with transmitters in large boxes. Second, making use of the observation that the receivers connectable to the origin form a Cox point process, we derive a large-deviation principle for the rescaled process of these receivers as the connection threshold tends to zero. Finally, we show how these results can be used to develop importance-sampling algorithms that substantially reduce the variance for the estimation of probabilities of certain rare events such as users being unable to connectComment: 29 pages, 2 figure

Making space for environmental problem solving: a study of the role of "place" in boundary choices using Georgia's statewide planning process as a case

In this dissertation, the concept of "problem bounding," argued by Bryan Norton and colleagues to be an important but understudied aspect of environmental problem solving, is operationalized and empirically investigated. The empirical part of the work involves participant observation and survey research on how diverse individuals – all of whom were invited by a state agency to advise the development of an institutional framework for statewide water planning – engaged in problem bounding both conceptually and in their choice of a spatial structure for ongoing water management. My particular focus is on the multiple ways in which the "place" an individual views the problem from shapes the way they engage in problem bounding. Although more research is needed and there are significant limitations to the data, my findings indicate that place – particularly in terms of location on an upstream/downstream continuum and rural/urban self-identification – does play a role in problem bounding. The dissertation concludes with a review and discussion of the major findings, and implications for the development of institutional frameworks that are both responsive to ecological dynamics and representative of the relevant public(s).Ph.D.Committee Chair: Bryan Norton; Committee Member: Christopher Weible; Committee Member: Gail Cowie; Committee Member: Michael Chang; Committee Member: Michael Hoffman
