The Kiosk Culture: Reconciling The Performance Support Paradox In The Postmodern Age Of Machines, Thomas Cavanagh

Electronic Theses and Dissertations

Do you remember the first time you used an Automatic Teller Machine (ATM)? Or a pay-at-the-pump gas station? Or an airline e-ticket kiosk? How did you know what to do? Although you never received any formal instruction in how to interact with the self-service technology, you were likely able to accomplish your task (e.g., withdrawing or depositing money) as successfully as an experienced user. However, not so long ago, to accomplish that same task, you needed the direct mediation of a service professional who had been trained how to use the required complex technology. What has changed? In short, the …

External Cavity Multiwavelength Semiconductor Mode-Locked Laser Gain Dynamics, Luis Archundia-Berra

Electronic Theses and Dissertations

External cavity semiconductor mode-locked lasers can produce pulses of a few picoseconds. The pulses from these lasers are inherently chirped with a predominant linear chirp component that can be compensated resulting in sub-picosecond pulses. External cavity semiconductor mode-locked lasers can be configured as multiwavelength pulse sources and are good candidates for time and wavelength division multiplexing applications. The gain medium in external cavity semiconductor mode-locked lasers is a semiconductor optical amplifier (SOA), and passive and hybrid mode-locked operation are achieved by the introduction of a saturable absorber (SA) in the laser cavity. Pump-probe techniques were used to measure the intracavity …

Police Organizational Performance In The State Of Florida:Confirmatory Analysis Of The Relationship Of The Environment And Design Structure To Performance, Jeffrey Goltz

Electronic Theses and Dissertations

To date, police organizations have not been rigorously analyzed by organizational scholars and most analysis of these organizations has been captured through a single construct. The purpose of this study is to develop confirmatory police organizational analysis by validating a multi-dimensional conceptual framework that explains the relationships among three constructs: environmental constraints, the design structures of police organizations, and organizational performance indicators. The modeling is deeply rooted in contingency theory, and the influence of isomorphism and institutional theory on the covariance structure model are investigated. One hundred and thirteen local police organizations from the State of Florida are included in …

Three-Photon Absorption Process In Organic Dyes Enhanced By Surface Plasmon Resonance, Ion Cohanoschi

Electronic Theses and Dissertations

Multi-photon absorption processes have received significant attention from the scientific community during the last decade, mainly because of their potential applications in optical limiting, data storage and biomedical fields. Perhaps, one of the most investigated processes studied so far has been two-photon absorption (2PA). These investigations have resulted in successful applications in all the fields mentioned above. However, 2PA present some limitations in the biomedical field when pumping at typical 2PA wavelengths. In order to overcome these limitations, three-photon absorption (3PA) process has been proposed. However, 3PA in organic molecules has a disadvantage, typical values of σ3' are small (10-81 …

General Social Trust And Political Trust Within Social And Political Groups: A Case Study, Weylan Craig

Electronic Theses and Dissertations

People in society with high levels of generalized social trust and political trust are more likely to engage in civic activism and participation. Therefore, people involved in social and political groups will likely have higher levels of generalized social and political trust than the general public. What lacks in this realm of scholarship is a solid comparison of trust among people involved in social and political groups. This case-study analysis of generalized social trust and political trust among social and political groups shows the trust that is not only generated within each group, but also which types of groups are …

Effects Of Atmospheric Turbulence On The Propagation Of Flattened Gaussian Optical Beams, Doris Cowan

Electronic Theses and Dissertations

In an attempt to mitigate the effects of the atmosphere on the coherence of an optical (laser) beam, interest has recently been shown in changing the beam shape to determine if a different power distribution at the transmitter will reduce the effects of the random fluctuations in the refractive index. Here, a model is developed for the field of a flattened Gaussian beam as it propagates through atmospheric turbulence, and the resulting effects upon the scintillation of the beam and upon beam wander are determined. A comparison of these results is made with the like effects on a standard TEM00 …

The Construct Validity Of A Situational Judgment Test In A Maximum Performance Context, Kevin Stagl

Electronic Theses and Dissertations

A Predictor Response Process model (see Ployhart, 2006) and research findings were leveraged to formulate research questions about, and generate construct validity evidence for, a new situational judgment test (SJT) designed to measure declarative and strategic knowledge. The first question asked if SJT response instructions (i.e., 'Should Do', 'Would Do') moderated the validity of an SJT in a maximum performance context. The second question asked what the upper-bound criterion-related validity coefficient is for SJTs in talent selection contexts in which typical performance is the criterion of interest. The third question asked whether the SJT used in the present study was …

Engagement, Trust, And Reciprocity: Exploring The Relationship Between Social Captial And Participation In Nonprofit Organizations, Rebecca Feiler

Electronic Theses and Dissertations

This study examines the extent to which various forms of social capital impact participation in nonprofit organizations. Previous research has focused on the importance of trust and engagement among social and political networks to form strong community ties that can cultivate the growth of social capital and promote participation in nonprofit organizations. The data analyzed in this study were derived from the Central Florida Social Capital Benchmark survey, collected at the University of Central Florida's Institute for Social and Behavioral Sciences. To represent social capital, related variables from the survey are combined to create indices that represent civic engagement and …

Dynamic Entrepreneurial Networks: An Investigation Of Entrepreneurs, New Ventures And Their Networks, Diane Sullivan

Electronic Theses and Dissertations

Entrepreneurs need resources to organize new venture offerings into marketplace-acceptable forms. Entrepreneurs use others' assistance via networks to obtain these resources. Research indicates that firms face resource dependencies, that likely change over time, where they must respond to those controlling resources. Although some work has investigated implications of new ventures' networks at one time period, little work has investigated the dynamic nature and associated outcomes of networks as they change due to different resource requirements as the venture develops. This research examines the dynamic nature of networks, due different resource requirements over time, and how these changes impact entrepreneurial outcomes …

Benchmarking Community Health Centers; Efficiency: Multivariate Analysis, Shriram Marathe

Electronic Theses and Dissertations

Community Health Centers (CHCs), designed to provide accessible and affordable health care services to low-income families, were first funded by the Federal Government as part of the War on Poverty in the mid-1960s. Improving healthcare organizational performance efficiency is paramount. It is an especially pressing need for CHCs' because they carry a disproportionate burden of caring for the uninsured within limited budgets. Prior studies suffer from conceptual and methodological limitations. A longitudinal multivariate analysis of factors influencing the performance of CHCs is needed. The purpose of this study is to benchmark CHC performance in terms of technical and cost efficiency, …

High Birefringence And Low Viscosity Liquid Crystals, Chien-Hui Wen

Electronic Theses and Dissertations

In this dissertation, liquid crystal (LC) materials and devices are investigated in order to meet the challenges for photonics and displays applications. We have studied three kinds of liquid crystal materials: positive dielectric anisotropic LCs, negative dielectric anisotropic LCs, and dual- frequency LCs. For the positive dielectric anisotropic LCs, we have developed some high birefringence isothiocyanato tolane LC compounds with birefringence ~0.4, and super high birefringence isothiocyanato biphenyl-bistolane LC compounds with birefringence as high as ~0.7. Moreover, we have studied the photostability of several high birefringence LC compounds, mixtures, and LC alignment layers in order to determine the failure mechanism …

The Relationship Of Student Achievement To Prinicpals' Self-Reported Use Of The Four Frame Theory, Donna Poniatowski

Electronic Theses and Dissertations

This study was developed to provide information about the relationship of principals' use of Bolman and Deal's (1991) four frame model of leadership to student achievement. The collection and analysis of student Florida Comprehensive Assessment Testing (FCAT) data over a 2 year period served as a measure to indicate whether or not an increase in reading mean scale score occurred from 2004 to 2005. Comparative analysis of both sets of data using multiple regressions was used to determine if there was a relationship between the self-reported leadership orientations of the principals and student achievement. In addition, the study was intended …

Enhancing Science Education Through Engaging Visual Content, David Kavanagh

Theses

In recent years a decline in the number of Irish students choosing to study science, at second level and on into third level, has become potentially harmful to the desired creation of a science-based knowledge economy. A primary contributing factor towards this decline is a lack of interest in the subject within the classroom, as was established by The Task Force on the Physical Sciences in 2002.

The primary aim of this Masters research is to investigate the role of visualisation in making the study of science more accessible and engaging to students to counter this decline. To this end …
