Understanding Employees' Behavioral Reactions To Aggression In Organizations, Marie Mitchell Jan 2006

Understanding Employees' Behavioral Reactions To Aggression In Organizations, Marie Mitchell

Electronic Theses and Dissertations

The purpose of this dissertation is to explore employees' behavioral reactions to the perceived aggression of others. Perceived aggression is defined as behavior that is perceived to be intentionally harmful by the intended target. A typology is developed that identifies two primary dimensions of behavioral reaction: (1) the form of the behavior (aggression/non-aggression) and (2) the direction of the behavior (toward the source of the harm/not toward the source of the harm). Based on these dimensions, the typology produces four categories of behavioral reactions: retaliatory aggression, displaced aggression, constructive problem-solving, and withdrawal. A model is then presented, which identifies various …

On The Use Of Variable Coherence In Inverse Scattering Problems, Erwan Baleine Jan 2006

On The Use Of Variable Coherence In Inverse Scattering Problems, Erwan Baleine

Electronic Theses and Dissertations

Even though most of the properties of optical fields, such as wavelength, polarization, wavefront curvature or angular spectrum, have been commonly manipulated in a variety of remote sensing procedures, controlling the degree of coherence of light did not find wide applications until recently. Since the emergence of optical coherence tomography, a growing number of scattering techniques have relied on temporal coherence gating which provides efficient target selectivity in a way achieved only by bulky short pulse measurements. The spatial counterpart of temporal coherence, however, has barely been exploited in sensing applications. This dissertation examines, in different scattering regimes, a variety …

Collaboration Enforcement In Mobile Ad Hoc Networks, Ning Jiang Jan 2006

Collaboration Enforcement In Mobile Ad Hoc Networks, Ning Jiang

Electronic Theses and Dissertations

Mobile Ad hoc NETworks (MANETs) have attracted great research interest in recent years. Among many issues, lack of motivation for participating nodes to collaborate forms a major obstacle to the adoption of MANETs. Many contemporary collaboration enforcement techniques employ reputation mechanisms for nodes to avoid and penalize malicious participants. Reputation information is propagated among participants and updated based on complicated trust relationships to thwart false accusation of benign nodes. The aforementioned strategy suffers from low scalability and is likely to be exploited by adversaries. To address these problems, we first propose a finite state model. With this technique, no reputation …
