Looking Inward: Higher Education Public Relations And Internal Communication, Kelly A. Campbell

Dissertations

There has been a decline in public good will toward institutions of higher education for nearly four decades. Resultantly, the public, media, and politicians call for greater transparency. It would be beneficial for institutions of higher education to utilize strategic means to communicate their stories, successes and brand directly to various publics. A critical, albeit often an overlooked public, are the employees of the university. They can serve as ambassadors for the university interacting with outside publics. In this capacity, not only do employees need to know information about their organization to function well at their positions, they also need …

Photoreception And Eye Regeneration Mechanisms In Planarians, Taylor R. Birkholz

Dissertations

Although humans lack the ability to regenerate complete organs and limbs following amputation or injury, there are many other species (both vertebrates and invertebrates) that can. Significant advances have been made in understanding the genetic mechanisms that regulate organ regeneration in these species, including regeneration of eye tissues such as the lens and retina. Planarians are an established historical model used to study regeneration due to their ability to regenerate any organ, including the eye. With recent advances in molecular genetic analyses, planarians are now an emerging model for the specific study of eye regeneration mechanisms. Furthermore, regeneration of the …

Concussion In Student Athletes: Prevention, Assessment, And Recovery, Miriam A. Carroll-Alfano

Dissertations

The research presented in this study examines concussion among athletes from the perspectives of prevention, assessment, and recovery. The first study examines concussion education for high school athletes by surveying 157 collegiate athletes, who primarily attended high school in Illinois and Indiana, about the previous concussion education, including whether they received mandated education, the methods and providers of education, and their ability to name a variety of concussion symptoms. This study finds that despite legislative mandates in these states, 20% of student-athletes continue to report not receiving concussion education in high school, with females more likely to report not receiving …

Towards Automated Domain-Oriented Lexicon Construction And Dimension Reduction For Arabic Sentiment Analysis, Hasan A. Alshahrani

Dissertations

Sentiment analysis is a type of text mining that uses Natural Language Processing (NLP) tools to identify and label opinionated text. There are two main approaches of sentiment analysis: lexicon-based, and statistical approach. In our research, we use the lexicon-based approach because the lexicon contains sentiment words and phrases which are the main linguistic units to express sentiments. More specifically, we work with domain-oriented lexicons as they are more efficient than general ones because the polarity is heavily driven by domains.

Arabic language has a degree of uniqueness that makes it hard to be processed with the available cross-language tools …

Evaluating Recommendations Versus Utilization Of Essential Components Of A Functional Analysis Procedure, Alissa Conway

Dissertations

Functional behavior assessment (FBA) has been identified as an essential process for behavior analytic practitioners to identify the variables maintaining challenging behaviors (BACB Professional and Ethical Compliance Code for Behavior Analysts (PECC), 3.01ab, 2014). FBAs include a range of strategies, including indirect measures (e.g., interviews and questionnaires) and direct measures of behavior (descriptive and experimental strategies). Functional analysis (FA) is typically considered the most sophisticated of the options subsumed under FBAs in that it involves both direct measures of behavior and experimental manipulation of hypothesized controlling variables to identify controlling variables for challenging behaviors. The results of FAs allow practitioners …

Integrated Compressive Sensing And Feature Descriptors- A Framework For Facial Recognition Systems, Ali Kadhem Jaber

Dissertations

Facial recognition is still a challenge in many applications, particularly in surveillance, security systems, and human-computer interactive (HCI) tools. The impact of real-world environmental variations on the performance of any facial recognition system can be significant. These variations may include illumination, facial expressions, poses, disguises (facial hair, glasses or cosmetics) and partial face occlusion. Furthermore, the number of images (samples) needed for facial recognition systems can be very large, much larger than what is typically required by an algorithm, and this is often made worse with expansion of the feature space dimensionality. Truly, the “curse of dimensionality” haunts any real-time …

Assessing Land Deformation And Sea Encroachment In The Nile Delta: A Radar Interferometric And Modeling Approach, Esayas Gebrekidan Gebremichael

Dissertations

Many of the deltas of the world are experiencing land deformation, subsidence or uplift of landmass, due to natural or anthropogenic causes, or a combination of both processes and causes. These deltaic settings are densely populated and border some of our world’s largest water bodies (oceans and seas). The land deformation, especially the subsidence component, when combined with the climate change-induced sea level rise, coastal erosion, and other anthropogenic drivers, will undoubtedly impact the population and economy of coastal areas of deltas. For the Nile Delta of Egypt, the land deformation processes and the factors that control the deformation processes …

A Systematic Comparison Of Functional Assessment Outcomes In Organizational Behavior Management, Nathan T. Bechtel

Dissertations

The primary purpose of this study was to compare the recommendation outcomes of two commonly utilized functional assessment tools in the field of Organizational Behavior Management (OBM): the Performance Diagnostic Checklist (PDC) and the Performance Flowchart. Recommendations made using these tools fell into one of three categories: antecedent-based, consequence-based, and uncategorized interventions. In order to assess the recommendations resulting from each of these tools, participants were trained to either (a) play the role of a manager with an organizational issue, or (b) play the role of a performance consultant. A between-groups design was utilized in which performance consultants used either …

The Place Of Art In Black Panther Party Revolutionary Thought And Practice: From Revolution To Reform, A Content Analysis, Michael James Macaluso

Dissertations

The Black Panther Intercommunal News Services (BPINS) was one of the most powerful black presses and a mechanism to build an imagined political community. Unfortunately, the scholarly and sociological literature examining the artwork of the Black Panther Party published in BPINS has been inadequate. Most work to date focuses solely on one artist, Emory Douglas, the Party’s Minister of Culture and primary editor of their press. Many other artists contributed to the collective endeavor of art and organization at large. The artwork of the Black Panther Party was a communal enterprise geared toward the promotion of political consciousness through visual …

Understanding The Experiences Of Students Re-Admitted After Academic Suspension As Part Of A University-Initiated Process: A Qualitative Study, Gary L. Versalle

Dissertations

Student persistence and retention continues to be a major issue facing most institutions of higher education. With ever more diverse student populations, researchers studied a multitude of groups and sub-groups of students based on ethnicity, sex, socioeconomic status, or age. These studies looked at how these various student groups can be supported and retained. Students who returned to school after having been academically dismissed are one group which has been consistently underreported. Reentry practices remained largely unchanged and still require the student to initiate the process. This phenomenological study examined the experiences of students accepted into the Reclaim the W …

Exploring The Impact Of Pretrained Bidirectional Language Models On Protein Secondary Structure Prediction, Dillon G. Daudert

Masters Theses

Protein secondary structure prediction (PSSP) involves determining the local conformations of the peptide backbone in a folded protein, and is often the first step in resolving a protein's global folded structure. Accurate structure prediction has important implications for understanding protein function and de novo protein design, with progress in recent years being driven by the application of deep learning methods such as convolutional and recurrent neural networks. Language models pretrained on large text corpora have been shown to learn useful representations for feature extraction and transfer learning across problem domains in natural language processing, most notably in instances where the …

The Effect Of Item Stem And Response Option Length On The Item Analysis Outcomes Of A Career And Technical Education Multiple Choice Assessment, Tina M. Koepf

Dissertations

Critical decisions in Career and Technical Education (CTE) can be based on assessment outcomes, requiring an essential focus on continuous improvement initiatives to provide increased multiple choice (MC) assessment validity. Previous research has determined that the presence of flawed test items negatively impacts student success; therefore, an MC taxonomy has been established and used in the assessment industry. While rigorous and successful Career and Technical Education (CTE) programs that enroll high-level academic students exist, many CTE programs enroll students with a wide spectrum of academic ability. Because many CTE students often have inferior reading skills, it is necessary to take …

The Determinants Of Affect, Emotional Arousal, And Autobiographical Memories On Music-Evoked Nostalgia, Alycia Sterenberg

Masters Theses

The purpose of this study is to further explore both person – level and context – level constructs established by Barrett et al. (2010) in relation to music-evoked nostalgia. This study also measures the strength of the relationship between self-reported arousal levels and electrodermal activity (EDA) as well as if they are good predictors of nostalgia. Methods include listening to personalized playlists to elicit feelings of nostalgia while electrodermal activity collects changes in arousal. Participants then answer questions of song familiarity, pleasure, arousal, and autobiographical salience to gather context – level constructs. Results indicate that both person – level and …

Optimization Of Analytical Inverse Heat Transfer Recovery Solution, Nathan Schick

Masters Theses

This thesis describes the different methods used when trying to solve inverse heat transfer problems, particularly those involving recovering heat flux. There are currently several techniques to measure the temperature history in an object subjected to heat transfer using various temperature sensors, however these types of sensors are gradually being replaced by Temperature Sensitive Paints (TSP), a technique that is more accurate and provides a better spatial resolution. TSP is a polymer that is applied on a base object. Changes in temperature in the polymer result in variations of the luminescence intensity in the paint. These variations can be captured …

A Structural And Stratigraphic Study Of The A-2 Carbonate In Southwest Michigan And Reservoir Characterization Of An A-2 Carbonate Gas Storage Field, Clayton Joupperi

Masters Theses

The Overisel and Salem gas storage fields of southwest Michigan annually store 34 Bcf of natural working gas in the upper dolomitized portion of the Silurian A-2 Carbonate. Porosity and permeability in these fields is thought to be enhanced by fracturing and dolomitization associated with the dissolution and collapse of underlying salt units. This study utilizes wire-line logs from 383 wells to explore the structural and stratigraphic controls on the deposition and diagenesis of the A-2 Carbonate in southwest Michigan. Core and thin sections from 4 wells serve as the primary data for investigating the depositional and diagenetic history of …

Stereotypic Repetitive Hand Flapping Movement Detector Children With Autism, Subodh Ashok Bansode

Masters Theses

The prevalence of Autism Spectrum Disorder (ASD) has increased at a significant rate in recent years, especially in developed nations such as the United States, Japan, and South Korea. Extensive research is being carried out to study the behavioral characteristics of the disease. Children affected with autism tend to exhibit a spectrum of symptoms depending on the severity of the disease. These behaviors are primarily repetitive, self-stimulatory, and stereotypic behaviors such as hand flapping (i.e., repeatedly shaking their hands), body rocking (i.e., swaying their body back and forth), drumming, walking around in a confined space, and walking with shortened steps …

Who Is In The “We”? Interrogating The African Union’S Agenda 2063 And Youth Political Participation., Job Shipululo Amupanda J.S

International Journal of African Development

Most analyses of the African Union (AU) focus on the politics of the state and presidents. There are very few analyses that focus on aspects such as youth development. This article departs from that tradition. It argues that although the youth were always part of important historical developments in Africa, they have remained on the periphery. In recent times, particularly since the transformation of the Organization of African Unity into the AU in the 2000s, the youth development agenda has begun to receive attention at the policy level. In 2015, the AU through Agenda 2063 went a step further by …

Does Inclusive Growth Matter For Regional Integration In Africa? An Empirical Assessment, Mohammed Shuaibu, Mamello Nchake

International Journal of African Development

Inclusive growth is an important channel through which African countries can foster higher regional integration especially through trade. This is because many African countries are characterized by exclusive growth, small and fragmented domestic markets that are landlocked and often prone to external shocks. Using an augmented gravity specification, this paper conducts an empirical investigation of the relationship between regional integration and inclusive growth in Africa. The adapted model is estimated using ordinary least squares, Pseudo Poisson maximum likelihood estimator and the Blundell-Bond system generalized method of moment estimator. The empirical results reveal that inclusive growth plays a vital role towards …

The Biopsychosocial Model: Application To Occupational Therapy Practice, Keith Gentry, Karen Snyder, Beth Barstow, Jordan Hamson-Utley

The Open Journal of Occupational Therapy

Despite the call for the profession to embrace a more integrated and holistic approach to practice, therapists may be faced with practical challenges, including issues relating to client caseloads, productivity demands, scheduling, entrenched practices, limitations on service imposed by payer sources, and staffing and budgetary restraints, to name but a few. Due to these limitations, current occupational therapy practice may be predisposed to adopt a more reductive approach to the evaluation and treatment of symptoms, underlying biological pathologies, and resulting impairments and disabilities. Therefore, psychological and social factors may be neglected, resulting in an unbalanced, fragmented, and incomplete approach to …
