An Examination Of An Antecedent And Consequences Of Supervisor Morally Questionable Expediency, Rebecca Greenbaum Jan 2009

An Examination Of An Antecedent And Consequences Of Supervisor Morally Questionable Expediency, Rebecca Greenbaum

Electronic Theses and Dissertations

Supervisor morally questionable expediency occurs when subordinates perceive that their supervisors engage in morally questionable behavior to expedite their work for self-serving purposes (Greenbaum & Folger, 2008). A supervisor's preoccupation with the bottom-line (Greenbaum, 2007; Greenbaum & Folger, 2008; Wolfe, 1988) is examined as an antecedent of morally questionable expediency. It was hypothesized that subordinates experience deontic reactions (Folger, 2001) in the form of a moral psychological contract violation. Consequently, subordinates were hypothesized to reduce performance, engage in antisocial behavior and supervisor-directed deviance. Survey data from 259 subordinate-supervisor dyads provided general support for this hypothesized model. However, post hoc analyses …

The Sheffer B-Type 1 Orthogonal Polynomial Sequences, Daniel Galiffa Jan 2009

The Sheffer B-Type 1 Orthogonal Polynomial Sequences, Daniel Galiffa

Electronic Theses and Dissertations

In 1939, I.M. Sheffer proved that every polynomial sequence belongs to one and only one type. Sheffer extensively developed properties of the B-Type 0 polynomial sequences and determined which sets are also orthogonal. He subsequently generalized his classification method to the case of arbitrary B-Type k by constructing the generalized generating function A(t)exp[xH1(t) + · · · + xk+1Hk(t)] = ∑∞n=0 Pn(x)tn, with Hi(t) = hi,iti + hi,i+1t i+1 + · · · , h1,1 ≠ 0. Although extensive research has been done on characterizing polynomial sequences, no analysis has yet been completed on sets of type one or higher …

Decoherence In Semiconductor Solid-State Quantum Computers, Diego Valente Jan 2009

Decoherence In Semiconductor Solid-State Quantum Computers, Diego Valente

Electronic Theses and Dissertations

In this dissertation we discuss decoherence in charge qubits formed by multiple lateral quantum dots in the framework of the spin-boson model and the Born-Markov approximation. We consider the intrinsic decoherence caused by the coupling to bulk phonon modes and electromagnetic environmental fluctuations. In the case of decoherence caused by phonon coupling, two distinct quantum dot configurations are studied and proposed as setups that mitigate its nocive effects : (i) Three quantum dots in a ring geometry with one excess electron in total and (ii) arrays of quantum dots where the computational basis states form multipole charge configurations.

Neurocognitive Correlates Of Body Image Disturbance, Elizabeth Frei Jan 2009

Neurocognitive Correlates Of Body Image Disturbance, Elizabeth Frei

Electronic Theses and Dissertations

Body image, broadly defined as an individual's general experience of his or her physical appearance, is a multidimensional phenomenon that has been found to affect functioning throughout the lifetime. Although some degree of dissatisfaction has been found to be a common aspect of the female experience, research suggests that a disturbance in body image can result in a number of clinical complications, particularly the development of an eating disorder (ED). Despite the relationship between body image and EDs, examinations of the cognitive underpinnings of the relationship between body image disturbance and EDs are relatively few and inconclusive. Research indicates that …
