An Analysis Of The North Carolina Cooperative Extension Service's Role In Bridging The Digital Divide, Antoine J. Alston, Lashawn Hilton, Chastity Warren English, Chanda Elbert, Dexter Wakefield

Journal of Extension

The study reported here sought to determine the perception of North Carolina County Cooperative Extension directors in regard to the North Carolina Cooperative Extension Service's role in bridging the digital divide. It was perceived by respondents that variables such as income, education, gender, disability status, race/ethnicity, age, and geographic location (rural versus urban) are major factors in the digital divide. Recommendations are made regarding North Carolina Cooperative Extension forming partnerships in order to narrow the digital divide in its regions, in addition to developing educational programming efforts in this area for all clientele served.

Faculty Publications - College of Physical Therapy

Background and Purpose: Golf is a popular sport played by hundreds of thousands of individuals of all ages and of varying skill levels. An orthopedic or sports-related injury and/or surgery may limit an individual’s sport participation, require him/her to complete a course of rehabilitation, and initiate (or resume) a sportspecific training program. Unlike the availability of evidence to guide postsurgical rehabilitation and sportspecific training of athletes from sports other than golf, there have only been two reports describing outcomes after surgery and for golfers. The purpose of this case report is to present a post-rehabilitation return to sporttraining program for …

A Comparison Of Intensive Care Unit Mortality Prediction Models Through The Use Of Data Mining Techniques, Sujin Kim, Woojae Kim, Rae Woong Park

Institute for Biomedical Informatics Faculty Publications

OBJECTIVES: The intensive care environment generates a wealth of critical care data suited to developing a well-calibrated prediction tool. This study was done to develop an intensive care unit (ICU) mortality prediction model built on University of Kentucky Hospital (UKH)'s data and to assess whether the performance of various data mining techniques, such as the artificial neural network (ANN), support vector machine (SVM) and decision trees (DT), outperform the conventional logistic regression (LR) statistical model.

METHODS: The models were built on ICU data collected regarding 38,474 admissions to the UKH between January 1998 and September 2007. The first 24 hours …

Recent Rates Of Forest Harvest And Conversion In North America, Jeffrey G. Masek, Warren B. Cohen, Donald Leckie, Michael A. Wulder, Rodrigo Vargas, Ben De Jong, S. P. Healey, Beverly Law, Richard Birdsey, R. A. Houghton, David J. Mildrexler, Samuel Goward, W. Brad Smith

Numerical Terradynamic Simulation Group Publications

Incorporating ecological disturbance into biogeochemical models is critical for estimating current and future carbon stocks and fluxes. In particular, anthropogenic disturbances, such as forest conversion and wood harvest, strongly affect forest carbon dynamics within North America. This paper summarizes recent (2000–2008) rates of extraction, including both conversion and harvest, derived from national forest inventories for North America (the United States, Canada, and Mexico). During the 2000s, 6.1 million ha/yr were affected by harvest, another 1.0 million ha/yr were converted to other land uses through gross deforestation, and 0.4 million ha/yr were degraded. Thus about 1.0% of North America's forests experienced …

Genetic Monitoring For Managers: A New Online Resource, Jeffrey Brian Stetz, Katherine Kendall, Christina D. Vojta, Genetic Monitoring (Gem) Working Group

Wildlife Biology Faculty Publications

Monitoring our natural resources will increasingly rely on genetic tools in order to understand and respond to invasive species, habitat degradation, fragmentation, disease, or climate-related changes. In recent years, the rapidly evolving field of genetic monitoring has seen explosive growth in sampling methods, genetic markers, and analytical approaches designed to estimate a wide range of parameters from connectivity to population growth rates. Some of these methods have taken root and now dominate particular aspects of population assessment and monitoring, whereas others have seen less success in real-world applications. To aid managers and researchers with limited genetics experience, we developed a …

Entrepreneurial Illegality: Empirical Examination Of The Effects Of Bribery And Tax Evasion On Firm Performance, Nnaoke Ufere

Student Scholarship

We examined the nexus of entrepreneurial illegality and firm performance in an emerging market by investigating the extent to which antecedent conditions such as economic constraints, bureaucratic demands, institutional pressures and entrepreneurial agency increase the supply of illegal opportunities exploited by entrepreneurs for private gains. Using 2009 World Bank Enterprise Survey data of 2599 small and medium-sized entrepreneurial enterprises (SMEEs) in Nigeria, we demonstrate that illegal entrepreneurial behaviors in developing markets--specifically bribery and tax evasion--affect firm performance measured by sales and employment growth. Results show that illegal opportunities significantly increase with bureaucratic and regulatory intervention in entrepreneurial activities, suggesting current …

Maternal Separation Affects Dopamine Transporter Function In The Spontaneously Hypertensive Rat: An In Vivo Electrochemical Study, Jacqueline S. Womersley, Jennifer H. Hsieh, Lauriston A. Kellaway, Greg A. Gerhardt, Vivienne A. Russell

Neuroscience Faculty Publications

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a developmental disorder characterised by symptoms of inattention, impulsivity and hyperactivity. The spontaneously hypertensive rat (SHR) is a well-characterised model of this disorder and has been shown to exhibit dopamine dysregulation, one of the hypothesised causes of ADHD. Since stress experienced in the early stages of life can have long-lasting effects on behaviour, it was considered that early life stress may alter development of the dopaminergic system and thereby contribute to the behavioural characteristics of SHR. It was hypothesized that maternal separation would alter dopamine regulation by the transporter (DAT) in ways that distinguish SHR …

Property's Memories, Eduardo M. Peñalver

Cornell Law Faculty Publications

This short essay, presented at Fordham's conference on the social functions of property (and in an earlier form at a conference on law and memory at USC), explores the relationship between property and memory. It distinguishes between property as the object of memory ("memory of property") and property as a medium of memory ("memory in property"). With respect to both kinds of memory, the common law expresses a great deal of ambivalence towards memory. Unlimited memory is no less dangerous to a system of property than it is to an individual’s ability to think. Recent reforms of adverse possession, the …

Children’S Independent Mobility : And The Mobile Phone: 8 To 12 Year Olds, Catherine Underwood

Program monitoring and evaluation

Children who know how to use a mobile phone, as opposed to those who don’t, are more likely to move about their neighbourhood without adult supervision, research from the Australian Council for Educational Research (ACER) suggests. The study, by ACER Research Fellow Ms Catherine Underwood, examined the extent to which knowing how to use a mobile phone is correlated with children’s physical activity and ability to move through their neighbourhood without adult supervision, also known as independent mobility. More than 800 Victorian primary school children aged between 8 and 12 years participated in the research, of which 84 per cent …

Novel Amino Acid Transporter-Targeted Radiotracers For Breast Cancer Imaging, Fanlin Kong

Dissertations and Theses (Open Access)

Breast cancer is the most common malignancy among women in the world. Its 5-year survival rate ranges from 23.4% in patients with stage IV to 98% in stage I disease, highlighting the importance of early detection and diagnosis. ¹⁸F-2-Fluoro-2-deoxy-glucose (¹⁸F-FDG), using positron emission tomography (PET), is the most common functional imaging tool for breast cancer diagnosis currently. Unfortunately, ¹⁸F-FDG-PET has several limitations such as poorly differentiating tumor tissues from inflammatory and normal brain tissues. Therefore, ¹⁸F-labeled amino acid-based radiotracers have been reported as an alternative, which is based on the fact that tumor cells uptake …

Evaluation Of Deformable Image Registration For Improved 4d Ct-Derived Ventilation For Image Guided Radiotherapy, Richard Castillo

Dissertations and Theses (Open Access)

Recent treatment planning studies have demonstrated the use of physiologic images in radiation therapy treatment planning to identify regions for functional avoidance. This image-guided radiotherapy (IGRT) strategy may reduce the injury and/or functional loss following thoracic radiotherapy. 4D computed tomography (CT), developed for radiotherapy treatment planning, is a relatively new imaging technique that allows the acquisition of a time-varying sequence of 3D CT images of the patient's lungs through the respiratory cycle. Guerrero et al. developed a method to calculate ventilation imaging from 4D CT, which is potentially better suited and more broadly available for IGRT than the current standard …

Purinergic Signaling Regulates Filopodia-Induced Zippering, Jessica Lynn Bowser

Dissertations and Theses (Open Access)

The molecular mechanisms that mediate endometrial cancer invasion and metastasis remain poorly understood. This is a significant clinical problem, as there is no definitive cure for metastatic disease. The purinergic pathway’s generation of adenosine and its activation of the adenosine receptor A2B (A2BR) induces cell-cell adhesion to promote barrier function. This barrier function is known to be important in maintaining homeostasis during hypoxia, trauma, and sepsis. Loss of this epithelial barrier function provides a considerable advantage for carcinoma progression, as loss of cell-cell adhesions supports proliferation, aberrant signaling, epithelial-to-mesenchymal transition, invasion, and metastasis. The present work provides strong evidence that …

Comparing Cropping System Productivity Between Fixed Rotations And A Flexible Fallow System Using Modeling And Historical Weather Data In The Semi-Arid Central Great Plains, Juan Jose Miceli-Garcia

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

In the Central Great Plains, the predominant crop rotation is winter wheat (Triticum aestivum L.)-fallow. Producers are looking to add diversity and intensity to their cropping systems by adding summer crops, however, the elimination of summer fallow may increase crop production risk. The objective of this study was to use crop simulation modeling to compare the productivity of two fixed rotations [winter wheat-corn (Zea mays L.)-fallow and winter wheat-corn-spring triticale (X Triticosecale Wittmack)] with simulated flexible fallow rotations. The flexible fallow rotations made the decision to plant triticale or use summer fallow prior to winter wheat seeding based …

Cultural Orientation And Drinking Behaviors Among Chinese University Students, Shiyuan Wang

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study aimed to develop a cultural orientation instrument among Chinese university students and to investigate the relationship between cultural orientation and their drinking behaviors. Four research questions were raised regarding these two objectives. A sample of 1421 students from universities in Beijing, Kunming and Wuhan participated in this study. The final instrument included 67 items consisting of 10 factors that loaded on two second-order factors: Chinese and Western culture. Thus, four categories of cultural orientation (Traditional, Western, Bicultural and Marginal) emerged, confirming the applicability of Berry’s acculturation theory in cultural orientation. The result also indicated that traditional oriented group …

Effective Science Teachers’ Professional Development: A Multiple-Case Study Of District-Level Science Supervisors’ Perspectives, Chris J. Schaben

College of Education and Human Sciences: Dissertations, Theses, and Student Research

At its heart, science teachers’ professional development is about continual growth and improvement (Yager, 2005). Conducting research to understand what constitutes effective professional development is inherently complex (Hewson, 2007). The imperative to link research on professional development to student achievement (Fishman, Marx, Best, & Tal, 2003) increases complexity of research on the topic. These complexities require multiple research approaches and indicate that all stakeholders could provide insights to identify what constitutes effective professional development. District-level science supervisors’ voices are missing from the data on effective science teachers’ professional development and this provides a potential gap in the literature (Banilower, Heck, …

Inquiry, Art And Consummatory Experience: A Deweyan Account Of The Instrumental And Aesthetic Modes In Human Well-Being, Eric A. Evans

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This dissertation argues that a Deweyan reconstruction of philosophical theories of human well-being is needed. While philosophical interest about human well-being has existed for millennia, significant interest in such theories among philosophers has re-emerged during the past twenty-five years. During this same time there has been a resurgence of interest in the work of John Dewey. His critique of the “philosophical fallacy” is used to examine the legitimacy and value of the theories of human well-being offered by Plato and L.W. Sumner in which the target for evaluation is “happiness” and the criterion is, respectively, P-justice or preference fulfillment. It …

The findings in study 1 revealed six prominent categories that inform women’s alcohol expectancy. Findings in study 2 provided 7-subscales (α > 0.7) for the instrument’s reliability and validity. Additionally, there were significant differences in alcohol expectancy by genders. Implications related to expectancy theory …

Examining The Effect Of Medical Risk, Parental Stress, And Self-Efficacy On Parent Behaviors And The Home Environment Of Premature Children, Kathryn Woods

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of this study was to examine the relationship between medical risk and parenting stress and the extent to which parental self-efficacy moderates the relationship between medical risk, parenting stress, specific parenting behaviors (i.e., parental responsivity, acceptance of child, parental involvement) and the home environment (i.e., organization of environment, learning materials, variety in experience, and IT-HOME total score) of premature children. Participants included 72 parent-child dyads with premature children between the ages of 7 and 35 months corrected age. Measures included parent reports of medical risk, stress, self-efficacy, and the IT-HOME. Results show that medical risk was not significantly …

World Food Crisis: Imperfect Markets Starving Development, A Decomposition Of Recent Food Price Increases, Christine Costello

College of Business: Dissertations, Theses, and Student Research

The recent decade has experienced two rather substantial food price spikes. This thesis sets out to provide an in-depth look at the recent food price increases by achieving two goals: assessing the forces driving food prices, and determining the magnitude of those forces. These goals are reached by reviewing selected rhetoric on the recent food price increases, analyzing case studies, and lastly determining our modeling capabilities in decomposing food price changes. Additionally, this thesis will serve as a tool for stakeholder's to better address critical policy issues surrounding food, agriculture, and energy policies.
