Computer Simulation And Modeling Of Physical And Biological Processes Using Partial Differential Equations, Wensheng Shen

University of Kentucky Doctoral Dissertations

Scientific research in areas of physics, chemistry, and biology traditionally depends purely on experimental and theoretical methods. Recently numerical simulation is emerging as the third way of science discovery beyond the experimental and theoretical approaches. This work describes some general procedures in numerical computation, and presents several applications of numerical modeling in bioheat transfer and biomechanics, jet diffusion flame, and bio-molecular interactions of proteins in blood circulation.

A three-dimensional (3D) multilayer model based on the skin physical structure is developed to investigate the transient thermal response of human skin subject to external heating. The temperature distribution of the skin is …

Identification And Characterization Of Proteins That Interact With Agamous-Like 15 (Agl15), A Mads-Domain Transcription Factor That Preferentially Accumulates In The Plant Embryo, Kristine Hill

University of Kentucky Doctoral Dissertations

AGAMOUS-Like 15 (AGL15) encodes a MADS-domain transcription factor that is preferentially expressed in the plant embryo, and may function as a regulator in embryonic developmental programs. A number of direct downstream targets of AGL15 have been identified, and while some of these target genes are induced in response to AGL15, others are repressed. Additionally, direct target genes have been analyzed that exhibit strong association with AGL15 in vivo, yet in vitro, AGL15 binds only weakly. Taken together these data suggest that AGL15 may form heterodimers, or ternary complexes with other proteins, thus modulating the specificity and function of AGL15 in …

Polymorphism Of Four Enantiotropic Crystalline Systems Containing Ni(Ii), H2O, 15-Crown-5 And No3-, Maxime Andre Siegler

University of Kentucky Doctoral Dissertations

The series of compounds [M(H₂O)₂(15-crown-5)](NO₃)₂, M = Mg, Mn, Co, Cu and Zn, has been extended to include two new phases for M = Fe and two new phases for M = Ni. The system [M(H₂O)₂(15-crown-5)](NO₃)₂ is remarkable for having many high-Z’ phases (Z’ > 1) with similar packing and for having solid-solid phase transitions through which there is no significant loss of crystallinity. The synthesis of the analogous Ni complex was carried out. Single-crystal X-ray diffraction showed …

Modulation Of Endothelial Cell Activation By Omega-6 And Omega-3 Fatty Acids, Lei Wang

University of Kentucky Doctoral Dissertations

Endothelial activation is considered to be an early and critical event in the pathology of atherogenesis which can be modified by environmental factors such as diet, pollutants, and lifestyle habits. Dietary andamp;ugrave;-6 and andamp;ugrave;-3 fatty acids have been reported to either amplify or diminish inflammatory responses related to atherosclerosis development. However, the interactions of andamp;ugrave;-6 and andamp;ugrave;-3 fatty acids with inflammatory cytokines or organic pollutants on endothelial cell activation are not well understood. The studies presented in this dissertation tested the hypothesis that andamp;ugrave;-6 and andamp;ugrave;-3 fatty acids alone, or in varying ratios can differently modulate pro-atherogenic mediators and inflammatory …

Governing Catastrophes: Security, Health And Humanitarian Assistance, David P. Fidler

Articles by Maurer Faculty

Recent catastrophes, and predictions of an increasing potential for more, have stimulated thinking about the best policy responses to these threats. This article explores how security concepts influence catastrophe governance. The article considers how globalization affects thinking about catastrophes and describes ways in which catastrophes have been conceptualized as governance challenges, such as the human rights approach to the provision of health and humanitarian assistance. The article explains how health and humanitarian assistance experienced ‘‘securitization’’ in the post-cold war period, a development that challenges rights-based strategies and creates complex and controversial implications for the prevention, protection and response functions of …

Special Issues Raised By Rape Trials, Aviva A. Orenstein

Articles by Maurer Faculty

Rape cases reveal core conflicts in the space where evidence, law, and ethics intersect. Such conflicts include the tension between victim protection and the rights of the accused, the challenges attorneys face trying to negotiate the demands of sensitive and emotionally difficult cases, and the role of the law in counteracting stereotypes and bias.

In this essay, I will begin by presenting the cultural milieu surrounding rape allegations, briefly reviewing attitudes towards perpetrators and victims. Next, I will attempt to capture the legal zeitgeist concerning rape, focusing on two recent phenomena: the reversal of false rape convictions based on DNA …

A Turner Syndrome Neurocognitive Phenotype Maps To Xp22.3., Andrew R Zinn, David Roeltgen, Gerry Stefanatos, Purita Ramos, Frederick F Elder, Harvey Kushner, Karen Kowal, Judith L Ross

Department of Pediatrics Faculty Papers

BACKGROUND: Turner syndrome (TS) is associated with a neurocognitive phenotype that includes selective nonverbal deficits, e.g., impaired visual-spatial abilities. We previously reported evidence that this phenotype results from haploinsufficiency of one or more genes on distal Xp. This inference was based on genotype/phenotype comparisons of individual girls and women with partial Xp deletions, with the neurocognitive phenotype considered a dichotomous trait. We sought to confirm our findings in a large cohort (n = 47) of adult women with partial deletions of Xp or Xq, enriched for subjects with distal Xp deletions. METHODS: Subjects were recruited from North American genetics and …

Modeling Reservoir Storage Scenarios By Consensus, Susan Kelly

Law of the Rio Chama

Computer modeling is a powerful scientific tool used to simulate the behavior of systems under a variety of possible future scenarios. Many scientists are involved in simulating the Rio Grande in various conditions, both natural and manmade. This article describes a collaborative process for developing simulations that can be used to understand the probable effects of changed operations of the system of Rio Grande reservoirs. Participants learned that even developing hypothetical model runs can be controversial. It was difficult to achieve consensus among a diverse group of interested parties on how to model future scenarios for management of the reservoirs.

History Of The Minnow Litigation And Its Implications For The Future Of Reservoir Operations On The Rio Grande, Lara Katz

Law of the Rio Chama

At the intersection of the Endangered Species Act and the Rio Grande lies the silvery minnow. In 1996, this tiny endangered fish found itself at the heart of a drought-sparked battle over the Rio Grande between an array of interests that has resulted in a tangled morass of litigation. The history of the minnow litigation, the legislative response it provoked, and the attempts at collaborative solutions all show a system under stress. The issues brought out in the struggle between the endangered silvery minnow and the various water users along the Rio Grande go to the heart of the relationships …

The Impact Of Full And Beneficial Use Of San Juan-Chama Project Water By The City Of Albuquerque On New Mexico's Rio Grande Compact Obligations, Kevin G. Flanigan, Amy I. Haas

Law of the Rio Chama

In 2004, the New Mexico State Engineer approved a permit allowing the City of Albuquerque to divert from the Rio Grande the approximately 48,200 acre-feet per year of water it receives from the San Juan-Chama Project, a trans-basin diversion project that imports water from the Colorado River basin to the Rio Grande basin. Over the last 30 years, the City has consumed little of its San Juan-Chama water but rather has provided it to various third parties for their use. However, at the end of 2008, the City plans to commence surface diversion of its San Juan-Chama water and anticipates …

Project Camelot And Military Sponsorship Of Social Science Research: A Critical Discourse Analysis, Ryan Hunt

Electronic Theses and Dissertations

"Project Camelot" was an ambitious social science research project conceived and funded by the Army, one whose scope and level of funding was unprecedented as of its inception in 1964. It was created in order to examine the potential for "internal war" and insurgency in the "developing countries" of the world, and to identify actions that the U.S. and its allies could take to prevent or suppress such insurgencies. Historians have described the Project as an event of particular importance in the history of American social science, and have argued that it is related to significant changes in their structure …

Red Clover As A Living Mulch: Implications For Sustainable Agriculture And Environmental Conservation, Bill Errickson

Master's Theses and Capstones

This study evaluated the short-term effects of a red clover living mulch on soil physical, chemical and biological properties, in an organically managed tomato agroecosystern in New Hampshire. Four treatments were established, including bare ground with no black plastic (BGNP), bare ground with black plastic (BGBP), red clover with no plastic (LMNP), and red clover with black plastic (LMBP). The effects of these practices are discussed in relation to total soil C and N, N mineralization, microbial biomass, mycorrhizal root colonization, aggregation, bulk density, moisture, and pH. Tomato yield, plant N uptake, and weed emergence were also determined. Large macroaggregates …

African American Perceptions Of Childhood Behavioral Disorders And Mental Health Services, Chant Wellington

Electronic Theses and Dissertations

This dissertation investigated African American parents/caregivers perceptions of childhood psychopathology and psychological services. The four participants of this study were African American parents/caregivers of children who were suspected by their respective schools of having symptoms of emotional, cognitive and or behavioral disorders. The researcher of this study asked these participants to describe their lived experiences of their children's functioning that school based evaluators consider atypical.

Data were obtained in the form of an initial phone interview. At a later date a face to face follow-up interview was audio taped and transcribed in order to obtain situated and general narratives.

The Use Of Detached Kelp (Ecklonia Radiata) By Seagrass-Associated Mesograzers In Temperate South-Western Australia, Christopher Doropoulos

Theses : Honours

The movement of nutrients and organisms between habitats provide important spatial subsidies on local and regional scales, resulting in increased primary and secondary production, especially where inputs supplement habitats of relatively low levels of comparable resources. In coastal south-western Australia, the brown kelp, Ecklonia radiata, is produced in large quantities on offshore reefs from where it detaches and passes through neighbouring habitats. This allochthonous resource is present in large quantities in seagrass meadows and thereby potentially influences the trophic dynamics of this habitat, providing an additional food source for grazers to those produced in situ. This study investigated the effects …

Depression, Rumination And Dependency In Relation To Age And Gender, Alison J. Lee

Theses : Honours

Extensive research has been carried out in the field of depression and its relation to age and gender. This article reviews relevant literature in the field of depression, rumination and dependency and the relationships of these to age and gender. It has been shown in numerous studies that depression, rumination and dependency are related and exist in comorbidity with each other. This article also reviews some of the research that has been conducted on age and gender with relation to rumination and dependency. It has been found in relation to rumination, dependency and depression that women are more susceptible than …

Externalising Behaviour Problems And The Influence Of Classroom Environments In The Early School Years ; Student-Teacher Relationships And Teacher Discipline: Their Relation To The Externalising Behaviours Of Kindergarten To Year 1 Students, Emma Spencer

Theses : Honours

Some of the most influential people in a child's life are the teachers who aid them in their transition into the education system and the complex social environment that it brings (Blancher & Eisenhower, 2006). Children who display externalising behaviours early in childhood often experience greater difficulties than other children when entering school and throughout their education experience (Hinshaw, Lahey & Hart, 1993; Liu, 2004). The student-teacher relationship established within the classroom and the disciplinary measures utilized by the teachers can have a profound impact on the child's development both academically and socially (Galen & Underwood, 1997; Hamre & Pianta, …

An Investigation Of The Relationship Between Inhibitory Motor Control And Low And High Trait Impulsivity In Non-Clinical Adults, Lindsay Vibert

Theses : Honours

Impulsivity is generally thought to refer to rapid, spontaneous and inappropriate behaviour. One causal view of impulsivity is that of executive inhibitory dyscontrol. Inhibitory control requires the suppression of an implicit or explicit response and may be assessed with laboratory behavioural tasks. Executive inhibition includes cognitive inhibition, interference control and behavioural inhibition. Impulsivity is frequently measured using self-report personality-based inventories. Investigations of the relationship between inhibitory control and impulsivity are uncommon. It is further proposed that there is a significant inverse relationship between a self-report measure of impulsivity (the Barratt Impulsiveness Scale) (Patton, Stanford, & Barratt, 1995) and a behavioural …

The Human Rights And Social Justice Mandate Of Social Work: Environmental Health And Well-Being For The Yarloop Community, Steven Denton

Theses : Honours

Social work has a dual concern, focusing on individuals and on their environments; however the discourse of the profession tends to be limited to the social, interpersonal or familial environment. Given the prospect of the current 'ecological crisis' having significant impacts upon human well-being, this research sought to expand this conceptualisation of 'environment' to include the physical environment. This study aimed to explore whether citizens experiences of environmental problems could be understood as social justice and human rights issues. Using an unobtrusive form of qualitative research with various written and audio visual accounts from citizens from the community surrounding Yarloop …

A Comparison Of Edge Detection Methods For Segmentation Of Skin Lesions In Mobile-Phone-Quality Images, Khanh Linh Hua

Theses : Honours

The world is faced with a rapidly increasing number of skin cancers every year. Melanoma is the most deadly type of skin cancer though it can be treated if it has been detected at an early stage. However, there is a shortage of dermatologists in rural areas. The increasing number of camera phones, together with improved coverage in rural areas gives some potential for tele-dermatology, whereby people with no local access to a dermatologist can send images of suspicious skin lesions to an expert for assessment. Merely relaying images to a human expert solves only part of the problem, there …

An Other(Ed) Handmaid's Tale : Child Care Workers: Seen But Not Heard, Kathrine Alice Sarah Whitty

Theses : Honours

Child care workers seem to have been forever assigned the lowest rung on the career ladder. Their low status has been attributed to several intractable factors: the socially devalued 'caring' nature of the role; the relatively small, disparate and non-hierarchically structured workplace; intimate association with an increasingly more marginalized group - children in their early childhoods; and an assumed complicity with a pseudo-surrogacy role of mother rendering them transgressors within a pro-natalist landscape. The institution of exclusive maternal care, for children prior to school, holds fast against the inexorable call for women to paid work. This dilemma resonates strongly within …

Using Machine Learning Techniques To Create Ai Controlled Players For Video Games, Bhuman Soni

Theses : Honours

This study aims to achieve higher replay and entertainment value in a game through human-like AI behaviour in computer controlled characters called bats. In order to achieve that, an artificial intelligence system capable of learning from observation of human player play was developed. The artificial intelligence system makes use of machine learning capabilities to control the state change mechanism of the bot. The implemented system was tested by an audience of gamers and compared against bats controlled by static scripts. The data collected was focused on qualitative aspects of replay and entertainment value of the game and subjected to quantitative …

M/Others : One Lens, Multiple Maternities, Toni Wilkinson

Theses : Honours

This body of photographic portraits re/presents the maternal relationship as a significant one in a cultural economy than 'downgrades motherhood', and fails to adequately recognise the contribution of mothers to society, as they struggle to uphold self and family in contemporary life. Throughout this work, which fuses religious visual art principles and photographic documentary, a more complex, powerful maternal figure emerges than the singular, passive and restrictive example of motherhood, commonly portrayed in art history. I undertake a comparative analysis between traditional Madonna and child icons and contemporary female photographers involved with maternal themes, to highlight that certain photographs facilitate …

Resident Community Perceptions Of The Socio Cultural Impacts Of Tourism And Host Guest Relations In A Least Developed Country : An Exploratory Study Of Phnom Penh, Cambodia, Sotear Ellis

Theses : Honours

This exploratory study of community perceptions of tourism impacts and host guest relations in a Least Developed Country (LDC) was undertaken in the Boeung Keng Kang I region of Phnom Penh city, Cambodia. A mixed methodology approach, with quantitative questionnaires of the local community and semi structured interviews with both the community and key informants from stakeholder groups, was used to investigate the appropriateness of social exchange theory and economic dependency theory to the LDC sustainable tourism development agenda set by the World Tourism Organization (WTO). While the concept of sustainable tourism incorporates the economic, environmental and sociocultural aspects of …

Understanding Personal Carers' Experiences Of Caring For Older People In Pain, Kristi Holloway

Theses : Honours

Pain is a complex phenomenon that can be challenging for staff working in residential aged care facilities (RACFs) (Fisher et al., 2002; Twycross, 2002). A high prevalence of pain reported by older individuals has been reported and suggests that further study in this area is warranted (Higgins, Madjar & Walton, 2004). Research suggests that a significant barrier to effective pain management in the elderly is the provision of primary care by care staff who have little or no education about pain, pain assessment or pain management (Allcock, McGarry & Elkan, 2002). Studies have identified personal carers as being in a …
