Pathology, East Africa

A case of multifocal Langerhans cell histiocytosis in a two-year-old child is presented where fine needle aspiration was helpful in achieving a rapid and accurate diagnosis in an appropriate clinical and radiological setting. This can avoid unnecessary biopsy and guide the management especially where access to histopathology is limited. The highly characteristic common and rare cytological features are highlighted with focus on differential diagnoses and causes of pitfalls.

Body Image And Body Mass Index: An Investigation Of Preadolescent Low-Income, Urban Ethnic Minority Girls, Amanda K. Ward

Master's Theses

Utilizing a sample of low-income, urban preadolescent African American and Latina girls, this study examined ethnic differences in two aspects of body image (i.e., body dissatisfaction and weight descriptions), and determined if this relation varied as a function of age. This study also examined the relation between the body image variables and self-esteem and BMI and self-esteem, and determined if these relations differed depending on age or ethnicity. Participants were recruited from 3rd through 5th grade at five Chicago Public Schools, and completed measures of body dissatisfaction, weight descriptions, self-esteem, and had their anthropometric measurements taken. Results showed that Latina …

Who Plays? Who Pays?: A Chicago Case Study Of Racism, The Lottery, And Education, Kasey Henricks

Master's Theses

Many Chicagoans are getting shortchanged, particularly when it comes to the money-exchange process between the Illinois Lottery (IL) and the Illinois State Board of Education (ISBE). In Illinois, a significant portion of lottery-generated revenues is earmarked to finance public education. Because these revenues are not generated equally across Chicago, some communities contribute more to education via the lottery than others. When these revenues are distributed in such a way that transfers money from one community to another, one community's fiscal gain comes at another's expense. So the question stands: Who plays and who pays? To answer this question, I measure …

Emotional Exhaustion, Work-Family Conflict, And Marital Satisfaction Among Professional Psychologists., Alisha Oscharoff

Master's Theses

While a wealth of research has examined how the occupational role affects family domain functioning, there is limited research investigating these issues among mental health professionals. Using a sample of 160 professional psychologists, this study examined the relationships between emotional exhaustion at work, work-family conflict (WFC), and marital satisfaction as well as gender differences in the strengths of these relationships. Analyses indicated that increased emotional exhaustion was associated with increased WFC and that both emotional exhaustion and WFC were negatively associated with marital satisfaction. However, WFC did not emerge as a significant mediator of the relationship between emotional exhaustion and …

Systemic Barriers To The Implementation Of International Education Policy: A Comparative Analysis Of The United States And France, Zephranie Buetow

Master's Theses

This thesis will argue that systemic barriers hinder the implementation of international education laws designed to eliminate inequality. Discriminatory practices are frequently embedded in national views. These views present themselves in legislative choices despite the form of government. Further, embedded beliefs influence a nation's commitment or resistance to international human rights instruments. An analysis of state commitment and resistance to international education laws will serve as a guide for identifying and understanding the legislative barriers preventing the enactment of meaningful international education policy.

Analyses on this subject have been reductionist in nature. They have failed to sufficiently consider all relevant …

Indigenous Intercultural Universities In Latin America: Interpreting Interculturalism In Mexico And Bolivia, Luciano Pedota

Master's Theses

The newly created Indigenous Intercultural Universities in Latin America challenge the conventional conception of universities and their "universal" quality. Such universities seek to decolonize knowledge by generating knowledge that is relevant to the communities in which they are located. These intentions, however, do not necessarily exclude the knowledge and research methods imparted by long-established Western universities. Instead, they have been conceived as Intercultural institutions designed to train indigenous community leaders capable of hybridizing or carrying out a "dialogue of knowledges"(Mato, 2007) and research methods of what are ultimately two different, and often times, opposing and contentious paradigms, one stemming from …

Projects Of Identity Creation In English Languate Textbooks Aimed At Adult Immigrants: 1900 And 2000, Steven Herbert Fehr

Master's Theses

The purpose of this study is to investigate the temporal parallels and differences between adult immigrant education and latent identity projects intertwined with the textbooks being used in the classrooms. By analyzing a sample of textbooks from both the turn of the 20th and 21st century I attempt to find both similarities and differences between these two time periods. These two periods are similar in that they are when the largest number of immigrants arrived in America, but in many ways (global context, technology, and political environment) they are also very different. How the American educational system responded to these …

Constructing A "Good" Colonial Society: Representations Of Philippine Colonial Education At The 1887 Philippine Exposition In Madrid And The 1904 St. Louis World's Fair, Erin Hardacker

Master's Theses

World's fairs and expositions were major social, political, economic, and cultural events in the late nineteenth and early twentieth centuries. These events were places where colonial states could display their achievements in their colonies, as well as produce knowledge and organize people as part of / in aid of the colonial project. It is a generally agreed fact among historians that the colonial exhibits at world's fairs and expositions were often idealized representations, or even deliberate misrepresentations, of colonies and colonial projects. Examining world's fairs and expositions should shed light on how colonial states developed and displayed their colonial education …

Being In The Know: Punk, Confrontation, And The Process Of Validating Truth Claims, Christopher Richard Penna

Master's Theses

Since the birth of punk, it has been a harbinger of trends within both youth culture and what cultural theorist Theodor Adorno calls the "culture industry" (Adorno & Horkheimer, 1947; Adorno, 1971). However, punk has never been fully embraced by the culture industry, largely, by design. Punk arose as a response, borne out of the frustration of a stagnant world that values profit over people (Sabin, 1999, p. 3). Present within opposition is confrontation--which is the very nature of punk. This thesis seeks to exemplify how punk uses confrontation as the instrument through which punk comes to know truths. The …

Accountability And Political Tolerance: "Sober Second-Thought" Or Knee-Jerk?, Erika D. Price

Master's Theses

This thesis explores the cognitive underpinnings of political tolerance. Past research suggests that political elites are more tolerant than the general population, regardless of political orientation. Survey results suggest that political expertise, interest, and attention to politics foster increased political tolerance, regardless of ideology, party, or the extent to which tolerance is carefully considered by the respondent.

Prosocial Behavior And Teamwork In Online Computer Games, Julia Elizabeth Fredrickson

Master's Theses

The use of technology for training purposes is a growing field. Many of the traits for successful team building are shared by a variety of video games, overcoming the limitations of traditional team-building exercises. The goal of this research project was to study social and teamwork oriented behaviors within the settings of online computer games. One hundred and eighty-one individuals completed an online survey in which they were asked questions regarding team-work behaviors. These individuals also participated in a game scenario which measured their social orientation. The hypotheses for this research were that individuals who play online computer games will …

The Ends Determine The Means: Activated Goals Explain The Decision To Confront, Kala Jean Melchiori

Master's Theses

Women believe that they would confront perpetrators of sexual harassment, but when put in a sexually harassing situation they rarely confront (Woodzicka & LaFrance, 2001). Women may overestimate their likelihood of confronting because they think they would be concerned with fairness, but in actuality the need to belong strongly dissuades women from confronting harassers. I tested this idea by randomly assigning women to be primed with a belonging, fairness, or no goal, and then had them predict how they would respond to sexually harassing or surprising interview questions. Women who viewed the sexually harassing interview questions predicted more confrontational behavior …

An Attack On One Is An Attack On All: Factors That Influence Responses To Witnessing Discrimination, Hilary E. Slover

Master's Theses

Witnessing discrimination against a racial minority should be threatening to both racial minority and majority group members, but for different reasons. One's racial group membership and one's relationship with the perpetrator could both serve as sources of threat to a third party observer. Ninety-two participants identified as racial majority group members (i.e., White) and 48 identified as racial minority group members (i.e., Asian, Black, and other). Each participant was asked to report one instance of discrimination perpetrated by a close other and one by a distant other. Some differences between minority and majority group members' responses emerged. For example, compared …

Global Influences And Resistance Within: Inclusive Practices And South Africa's Apartheid Government, Jean Marie Fagin

Master's Theses

South Africa's racially segregating apartheid government officially lasted for over forty years, from 1948 to 1994. Black South Africans were the victims of established oppression resulting in poverty, poor health care, and limited educational opportunities. Black South Africans with disabilities faced even greater exclusion from society due to their physical and cognitive challenges. Education for black students was neither compulsory nor free, and few black students with disabilities received services.

During the apartheid regime (1948-1994), disability issues were being address globally. The United Nations issued declarations, conventions, and a programme of action devoted to people with disabilities. In the early …

Protein Kinase C Δ Is Critical For Nucleotide Excision Repair Of Cyclobutane Pyrimidine Dimers, Christopher Michael Negro

Master's Theses

Nucleotide excision repair (NER) is the process by which cells identify and repair bulky, helix-distorting DNA lesions such as ultraviolet (UV) radiation-induced cyclobutane pyrimidine dimers (CPD) and 6-4 photoproducts (6-4PP). NER in human cells is a complex biochemical process requiring several complementation groups. Defects in complementation group genes result in rare, autosomal recessive cancer syndromes such as xeroderma pigmentosum (XP), cockayne syndrome (CS), and trichothiodystrophy, supporting the tumor suppressive effects of NER. Protein Kinase C delta (PKCδ) expression is lost in squamous cell carcinomas where it functions as a tumor suppressor gene. Additionally, in response to UV radiation, PKCδ is …

The River Continuum Redux: Aquatic Insect Diets Reveal The Importance Of Autochthonous Resources In The Salmon River, Idaho, Kathryn Vallis

Master's Theses

Along a river network, changes in the physical characteristics of a stream - changes articulated by the River Continuum Concept (RCC) - have been predicted to influence stream food webs, particularly the resources supporting aquatic macroinvertebrates. Although diets of macroinvertebrates can track resource availability along the longitudinal gradient of streams, insect diets were not assessed in the original RCC study; rather, insects were grouped into functional feeding groups (FFGs). In addition, global climate change is increasing the frequency and spatial extent of wildfire and beetle outbreaks throughout the western United States and could affect riparian vegetation and the amount of …

Modularizing Crosscutting Concerns In Software, Nalin Saigal

USF Tampa Graduate Theses and Dissertations

Code modularization provides benefits throughout the software life cycle; however, the presence of crosscutting concerns (CCCs) in software hinders its complete modularization. Traditional modularization techniques work well under the assumption that code being modularized is functionally orthogonal to the rest of the code; as a result, software engineers try to separate code segments that are orthogonal in their functionality into distinct modules. However, in practice, software does not decompose neatly into modules with distinct, orthogonal functionality. In this thesis, we investigate the modularization of CCCs in software using two different techniques.

Firstly, we discuss IVCon, a GUI-based tool that provides …

Identification Of Patient Recovery Patterns After Cardiovascular Surgery Based On Laboratory Tests Results, Alcides Ricardo Santander Mercado

USF Tampa Graduate Theses and Dissertations

In this dissertation is proposed a methodology to identify patient's recovery patterns after cardiovascular surgery based on laboratory tests results. The main purpose is to enhance the understanding of the manifestations of postsurgical complications in patients who underwent cardiovascular surgery. The analysis of patients' recovery process is based on the relationship between plasma calcium, ionized calcium and platelet count over time.

Laboratory results from the James A. Haley Veterans' Hospital databases, related to patients admitted to the Surgical Intensive Care Unit (SICU) after cardiac surgery (coronary artery bypass, aortic value replacement and mitral valve replacement), are used. These databases contain …

The Effects Of Manipulating Conditioned Establishing Operations On The Acquisition Of Mands In Children With Autism Spectrum Disorders, Claudia Troconis

USF Tampa Graduate Theses and Dissertations

In Verbal Behavior, Skinner (1957) suggested that each verbal operant has independent response functions, in which acquiring one does not automatically result in the other, unless transfer between the verbal operants is directly trained. Although several researchers have shown that mands and tacts are functionally independent, more recent research has demonstrated that mands may emerge following tact training. However, this research has not clarified the influence of establishing operations on the emergence of pure mands following tact training. Therefore, the present study investigated the effects of tact training on the acquisition of impure and pure mands in children with autism …

Atrial Fibrillation Signal Analysis, Raja Sarath Chandra Prasad Vaizurs

USF Tampa Graduate Theses and Dissertations

Atrial fibrillation (AF) is the most common type of cardiac arrhythmia encountered in clinical practice and is associated with an increased mortality and morbidity. Identification of the sources of AF has been a goal of researchers for over 20 years. Current treatment procedures such as Cardio version, Radio Frequency Ablation, and multiple drugs have reduced the incidence of AF. Nevertheless, the success rate of these treatments is only 35-40% of the AF patients as they have limited effect in maintaining the patient in normal sinus rhythm. The problem stems from the fact that there are no methods developed to analyze …

Robotic Hand Evaluation Based On Task Specific Kinematic Requirements, Carlos Rafael Neninger

USF Tampa Graduate Theses and Dissertations

With the rise autonomous and robotic systems in field applications, the need for dexterous, highly adaptable end effectors has become a major research topic. Control mechanisms of robotics hands with a high number independent actuators is recognized as a complex, high dimensional problem, with exponentially complex algorithms. However, recent studies have shown that human hand motion possesses very high joint correlation which translates into a set of predefined postures, or synergies. The hand produces a motion using a complementing contribution of multiple joints, called synergies. The similarities place variables onto a common dimensional space, effectively reducing the number of independent …

An Analysis Of Remote Biometric Authentication With Windows, Brandy Marie Eyers

USF Tampa Graduate Theses and Dissertations

One thing that everyone seems to be worried about when it comes to his or her computer is security. If your computer is not secure then private information could be stolen. Many people now use passwords to protect themselves though they are discovering that using multi-factor authentication is much more secure. It allows you to use multiple different proofs of who you are. Biometrics is one of the ways to prove identity. Using it, you could log into a system with just a fingerprint, which is something that is very difficult to steal. We present a suite of software tools …

The desire is to provide low delay, cost effective …

Resource Allocation Methodologies With Fractional Reuse Partitioning In Cellular Networks, Hazar Aki

USF Tampa Graduate Theses and Dissertations

Conventional cellular systems have not taken full advantage of fractional frequency reuse and adaptive allocation due to the fixed cluster size and uniformed channel assignment procedures. This problem may cause more fatal consequences considering the cutting-edge 4G standards which have higher data rate requirements such as 3GPP-LTE and IEEE 802.16m (WiMAX). In this thesis, three different partitioning schemes for adaptive clustering with fractional frequency reuse were proposed and investigated. An overlaid cellular clustering scheme which uses adaptive fractional frequency reuse factors would provide a better end-user experience by exploiting the high level of signal to interference ratio (SIR). The proposed …

An Evaluation Of Booster Training Using Video Modeling With Foster Parents, Anna Katherine Caravello

USF Tampa Graduate Theses and Dissertations

In order for foster parents to be prepared to manage problem behavior and develop a positive relationship with a child in their home, local foster care agencies require these parents to attend parent training classes. Unfortunately, even foster care agencies that offer empirically validated parent training courses are unable to prevent the parents' performance from decreasing over time (Cowart, Iwata, & Poynter, 1984; Forehand & King, 1977; Mueller et al., 2003). However, researchers have created booster training sessions to counteract this issue. Booster training sessions allow participants to attend a brief refresher course on skills they have previously learned. Another …

The Impact Of Pharmacy Work Design On Pharmacist Productivity, Nicholas Allen Coblio

USF Tampa Graduate Theses and Dissertations

Healthcare costs in the United States continue to grow at an alarming rate. Concerning the cost of medications, there are a number of factors that drive these costs. While personnel costs are not the largest of these, they do contribute a significant portion. The cost of the cognitive component of order processing by pharmacists can range from three dollars to over six dollars per prescription depending on the production throughput of the pharmacist.

Studies at the organization which was the focus of the research, as well as reports in the literature, indicated that work disruption and other environmental factors could …

Mental Health Courts Effectiveness In Reducing Recidivism And Improving Clinical Outcomes: A Meta-Analysis, Brittany Cross

USF Tampa Graduate Theses and Dissertations

The present study is a review of mental health court literature assessing their effectiveness in reducing recidivism and improving clinical outcomes for participants using meta-analytic techniques. A total of 20 studies that included sufficient information to compute the standardized mean difference effect size, focused on adult populations, and were within the United States were included in the analysis. Only experimental and quasi-experimental research designs were obtained. Using Cohen’s d (1988) guidelines, mental health courts …

Analytical Methods To Support Risk Identification And Analysis In Healthcare Systems, Laila Nadime Cure Vellojin

USF Tampa Graduate Theses and Dissertations

Healthcare systems require continuous monitoring of risk to prevent adverse events. Risk analysis is a time consuming activity that depends on the background of analysts and available data. Patient safety data is often incomplete and biased. This research proposes systematic approaches to monitor risk in healthcare using available patient safety data. The methodologies combine traditional healthcare risk analysis methods with safety theory concepts, in an innovative manner, to allocate available evidence to potential risk sources throughout the system. We propose the use of data mining to analyze near-miss reports and guide the identification of risk sources. In addition, we propose …
