The Effect Of Gender Beliefs On Self-Determined Motivation As Measured By Organizational Citizenship Behaviors And Workplace Deviant Behaviors, Ryan Jaramillo

Electronic Theses, Projects, and Dissertations

Employees are gauged by their motivation to complete their required job responsibilities, as losses in motivation can result in losses to organizations. Understanding motivation is necessary to achieving beneficial organizational outcomes such as organizational citizenship behaviors (OCBs) while reducing detrimental employee outcomes such as workplace deviant behaviors (WDBs). To this end, the present study analyzes motivation not through a dichotomy of intrinsic and extrinsic motivation, but through a spectrum of self-determination for its relationship to employee behaviors. Gender is a potential moderator that can have important moderating effects between motivation and subsequent outcomes in the workplace. The purpose of this …

Exploiting Randomness In Secret Sharing, Cailyn Bass

All Theses

Shamir's (k,n)-threshold scheme is a method for sharing a secret among n participants such that any group of k or more participants can recover the secret. Additionally, any group of participants with size less than k should learn nothing about the secret. The scheme works by distributing a share to each participant, where each share is a linear combination of the secret and k-1 random symbols. This allows any group of k or more participants to solve a linear system to compute the secret. Any group of less than k participants does not have enough to determine anything about the …

Bounding The Convex Hull Relaxation Of The Unit Commitment Problem With The Shapley-Folkman Theorem, Lauren Henderson

All Theses

The Unit Commitment (UC) problem finds an optimal schedule for a set of generators by minimizing the total operation cost subject to demand and operational constraints. The UC problem is often modeled with a mixed-integer linear program (MILP). We employ the Shapley-Folkman Theorem to provide a bound on the size of fractional solutions of its convex hull relaxation. This result is used to obtain a bound on the optimality gap between the MILP and the convex hull relaxation, which is further tightened using several problem-specific properties of UC. We conduct extensive numerical experiments to study the tightness of this threshold, …

Causality Analysis For Neural Network Security, Bing Sun

Dissertations and Theses Collection (Open Access)

While neural networks are demonstrating excellent performance in a wide range of applications, there has been a growing concern on their reliability and dependability.Similar to traditional decision-making programs, neural networks inevitably have defects that need to be identified and mitigated at times. Neural networks are usually inherently black-boxes and do not provide explanations on how and why decisions are made. As a result, these defects are more ``hidden" and more challenging to eliminate. It is thus crucial to develop systematic approaches to identify and mitigate defects in a neural network in a rigorous way.

In this dissertation, we focus on …

The Relationship Between A Transient Scientific Phenomenon And Local Journalism At The Beginning Of The Gilded Age, Thomas Hockey

Faculty Publications

In the United States, the nineteenth century was the halcyon era for local newspapers. These publications were the primary source of public information at a time when other periodicals and books had low circulation. The purpose of this paper is to explore how local journalism in the nineteenth-century United States dealt with an occasion outside the boundaries of the commonplace: an unfamiliar natural phenomenon. My example is the total solar eclipse of 7 August 1869. Editors and journalists of the time largely were unaccustomed to covering celestial events. Nevertheless, they sensed—correctly—an interest in the solar eclipse. Articles about the approaching …

The Pagan Reception Of Judaism From The Sibylline Oracles: Insights From Pseudo-Seneca’S Octavia Regarding The Creation And Circulation Of Oral Sibylline Oracles By The Plebs, Kenneth Atkinson

Faculty Publications

According to tradition, the original collection of Sibylline Books ac­quired by the Roman monarch Tarquinius Priscus, which were kept in the Temple of Jupiter in the capital, were lost in the fire of 83 BCE. In 76 BCE, the Senate ordered the college of the quindecimviri to travel to the traditional centers of Sibylline activity in the East to find Sibylline Oracles to replace those destroyed in the fire. According to Lactantius, these officials collected many Oracles from private individuals. This reference suggests that Sibylline Oracles circulated widely. However, based on the witnesses regarding their consultation, it appears that the …
