From Herd Diversification To Livelihood Diversification As A Response To Poverty: The Case Of The Waso Boran Of Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Abdillahi A. Aboud

Environment and Society Faculty Publications

The Waso Boran of northern Kenya used to have large, mobile, and diverse herds of livestock that exploited equally large and diverse rangelands. Forty years of human population growth, drought, environmental change, and lack of relevant policies have altered this situation, however, with the majority of Waso Boran today being livestock poor and engaged in a variety of non-pastoral activities to diversify their livelihoods. One-third of 540 households we surveyed in Isiolo District now have ten head of cattle or less, and a larger census suggests that only 15 percent of households can currently be categorized as mobile pastoralists. The …

A Hairy Predicament: The Problem With Long Hair In The 1960s And 1970s, Andrew Robert Herrick

Graduate Theses, Dissertations, and Problem Reports (ETD)

By the mid-1970s long hair worn by much of the American youth evoked little comment and indeed was considered fashionable. But during much of the previous two decades male hair length was a contentious issue that divided the generations. The struggle over hair in many ways epitomized the sixties generation's challenge to authority and their claim to individual rights. During the era, the meaning of long hair changed dramatically from what it was during the fifties. It began as a symbol of youth culture rebellion linked to music. By the latter part of the sixties, however, it became associated with …

The Relationship Between Technical Support And Pedagogical Guidance Provided To Faculty And Student Satisfaction In Online Courses, Philip R. Ice

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined the relationship between levels of technical support and pedagogical guidance provided to faculty and student satisfaction in online courses. Online learning is a rapidly evolving area of education, yet compared to traditional face-to-face learning very little is known about pedagogical techniques and best practices. This study explores the relationships between two factors that have been demonstrated to influence faculty satisfaction, technical support and pedagogical guidance (the predictor variables), and student satisfaction (the criterion variable) in online courses. The study uses quantitative methods to determine if varying levels of predictor variable input are related to changes in the …

The Extrinsic Apoptotic Pathway In Aged Skeletal Muscle: Roles Of Tumor Necrosis Factor-Alpha And Interleukin-15, Emidio E. Pistilli

Graduate Theses, Dissertations, and Problem Reports (ETD)

Apoptosis is implicated in the loss of skeletal muscle mass following periods of reduced activity (i.e.-disuse) as well as during the normal aging process (i.e.-sarcopenia). Aging is also characterized by elevations in circulating cytokines, specifically TNF-alpha, which has been associated with the sarcopenic process. The specific signaling components that participate in the pro-apoptotic pathway downstream of the type I TNF receptor (i.e.-extrinsic apoptotic pathway) within skeletal muscle have not been clarified. Additionally, few studies have been performed with the aim of disrupting this apoptotic pathway, and thereby sparing muscle mass in the aged. Therefore, the purposes of this dissertation were …

A Model Of Stabilizer Roll Bearing For A Continuous Hot-Dip Galvanizing Line, Vishnu V. Rachamalla

Graduate Theses, Dissertations, and Problem Reports (ETD)

The short service life of the hardware inside the molten zinc pot is often the cause for the unscheduled shutdown of a galvanizing line. The lifetime of the hardware used in these lines is not only a function of materials used but also on factors such as line speed, sheet tension, bearing contact pressure, bearing alignment, zinc pot temperature, corrosion as a function of pot chemistry, and surface finish of the materials used. Dr. James Snider has developed a comprehensive data file on the wear rate and corrosion properties of currently available bearing materials. Dr. Snider's dissertation research as well …

Supplemental Forages For Grazing Beef Cattle In Appalachia, Evans Abenga Basweti

Graduate Theses, Dissertations, and Problem Reports (ETD)

growth and availability of forages. Cool-season perennial grasses are the basic source of feed for cow-calf production. Producers require information about incorporating annual forages into grazing systems during months of low productivity of the cool-season species. An experiment was conducted for two years (2004 and 2005) at Reedsville Experimental Farm, West Virginia University, to determine growth rate, herbage accumulation and quality of sudangrass, and pearl millet grown in summer and triticale and a mixture of annual ryegrass and turnips grown in the fall on the same land. Two methods of herbage control, burning and glyphosate, were used to kill existing …

Differential Binding Of Hnrnp K, L And A2/B1 To An Exonic Splicing Silencer Element Located Within Exon 12 Of Glucose -6 -Phosphate Dehydrogenase Mrna, Brian Nelson Griffith

Graduate Theses, Dissertations, and Problem Reports (ETD)

The expression of most lipogenic enzymes is regulated through the effects of dietary polyunsaturated fatty acids on transcription. However, we have observed that the regulation of Glucose-6-phosphate dehydrogenase (G6PD) by polyunsaturated fatty acids occurs through a novel posttranscriptional mechanism. RNA reporter assays were used to map the cis-acting element by measuring the regulation of each RNA reporter construct transfected into primary rat hepatocytes. All RNA reporter constructs were regulated by polyunsaturated fatty acids with the exception of RNA reporter constructs lacking exon 12. Therefore, polyunsaturated fatty acids regulate the constitutive splicing of G6PD mRNA through a cis-acting element located within …

Esterase Inhibition By Grapefruit Juice And Its Components Leads To Newly Identified Drug Interactions, Ping Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

Grapefruit juice (GFJ) is well known to be a potent inhibitor of the CYP3A enzyme leading to drug-drug interactions. This study describes a newly identified potential of GFJ in mediating pharmacokinetic drug-drug interactions due to its capability of esterase inhibition. The study demonstrates that GFJ inhibits purified porcine esterase activity towards para-nitrophenylacetate (PNPA) and the prodrugs lovastatin and enalapril. In rat and human hepatic or gut S9 fractions and rat gut lumen GFJ inhibited the hydrolysis of enalapril and lovastatin, which are known to be metabolized principally by esterases, with lovastatin metabolized also by CYP3A. In Caco-2 cells, permeability of …

Applying Stages Of Change Theory To An Acute Pain Situation: Development Of The Childbirth Stages Of Change Questionnaire (Csocq), Rebecca K. Widoe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Various self-management methods and pharmacological agents are available to relieve childbirth pain. Decisions about pain management during labor have medical, psychological, and sociological ramifications, yet research investigating the selection of childbirth pain management strategies is scarce. The purpose of the current study was to develop a self-report instrument, the Childbirth Stages of Change Questionnaire (CSOCQ), to assess a pregnant woman's readiness to self-manage childbirth pain. Items representative of five levels of readiness were generated by experts. Next, 3 pregnant women evaluated items for content validity. A pilot CSOCQ was administered to 536 undergraduate women. Factor analysis and item-reliabilities were conducted …

No One Flunks Museum: An Overview Of Learning Theory And Its Implementation In Formal And Informal History Education, Nichole D. Smith

Seton Hall University Dissertations and Theses (ETDs)

The transition of museums from institutions for the knowledgeable to places for those seeking knowledge has brought about a need for those educating in museums to better understand the ways in which people learn. This paper introduces and explains theories, psychological and educational, that are applicable to learning such as Constructivism, Multiple Intelligences, and the Contextual Model of Learning. Observations of informal and formal history and social studies lessons or programs presented to students ages 3-16 provide the framework for understanding how well these theories of learning are being implemented in the museum. Comparison of history museum programs (informal education) …

Software Application For Emergency Responders, Safer 2.0, Saritha Reddy Potula

Graduate Theses, Dissertations, and Problem Reports (ETD)

The SAFER 2.0 was developed as a web based information system for the First Responders involved in dealing with the hazardous materials incidents. The software tool enables First Responders to view and identify the substances involved in a hazard via a secure Internet connection. The tool also aids in identifying the unknown substances based on the physical description (color, odor, texture, gas/liquid, etc.), symptoms and other information available at the site of the incident. The system is based on the 2004 North American Emergency Response Guidebook (ERG2004) and NIOSH Pocket Guide (NPG). ERG2004 was developed for use by firefighters, police, …

Phytoformations Of Silver And Gold Nanoparticles, Brooke A. Fridley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Stevia and red beet suspension cultures were examined for uptake of silver from AgNO3 solution. Alfalfa and mung bean sprouts were also studied for silver accumulation when grown in AgNO3 solution. AA analysis confirmed the presence of silver in both sprouts and suspension cultures after exposure to AgNO3 solution, despite the toxic effects of silver on the living matter.;Extract from Pelargonium graveolens underwent reaction with both AgNO3 and KAuCl4 to form silver or gold nanoparticles. For the reaction with AgNO3, light was required to initiate the reaction. In contrast, reactions producing gold nanoparticles did not require light to react. Oxygen …

Afferent Regulation Of A15 Dopamine Neurons In The Ewe, Adrienne L. Bogusz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ovine reproduction is characterized by a breeding season and an anestrous season. Seasonal anestrus is induced by increased responsiveness of the GnRH neurosecretory system to estrogen (E) negative feedback. Previous studies have shown that inhibitory A15 dopamine neurons mediate this increased sensitivity to E, however, these neurons lack E receptors. In this thesis we performed three experiments. For experiment 1 we looked at the specific sites of actions that thyroid hormones act to cause neuronal plasticity of A15 DA neurons, utilizing dual-labeled immunocytochemistry. The results of this study demonstrated no change in dendrite morphology or the number of close contacts …

Development Of An Animal Model Of Choice Between Aversive Events, James W. Diller

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present study examined variables controlling choice between aversive events using pigeons as subjects. Initially, a titration procedure using variable-interval (VI) schedules of food and shock delivery contingent on keypecking was conducted to determine a moderately aversive shock intensity and duration. Subjects were then presented with a choice between food delivery followed by either a single shock or three shocks in a discrete-trials procedure. The change in context affected the aversiveness of the shock. In the VI condition, shock presentation resulted in 40-60% decrease in response rates. In the discrete-trials procedure, however, responding was "all-or-none." Thus, an attempt to redetermine …

Collective Action By Women’S Groups To Combat Drought And Poverty In Northern Kenya, D. Layne Coppock, Solomon Desta, Getachew Gebru, Adan Wako, Ibrahim Aden, Chachu Tadecha, Seyoum Tezera

Environment and Society Faculty Publications

Collective action can be an effective means of local development and risk reduction among rural people, but few examples have been documented in pastoral areas. We conducted extensive interviews for 16 women’s groups residing in northern Kenya. Our objectives were to understand how groups were formed, governed, and sustained and what activities they have pursued. The groups we interviewed were 10 years old, on average. Charter memberships averaged about 24 women, 20 of whom were illiterate. Half of the groups formed after facilitation by a development partner and half formed spontaneously. Groups are governed under detailed constitutional frameworks with elected …

Community Perceptions Concerning Key Ecological Resources At Risk In Baringo District, Kenya, D. Layne Coppock, Mark N. Mutinda, Abdillahi A. Aboud

Environment and Society Faculty Publications

Key ecological resources in arid and semi-arid lands are often characterized by small patches of seasonal grazing and important water points that lend critical support to entire production systems. When key resources are degraded or lost, production systems can be badly compromised. The Baringo District of north-central Kenya is well known for enduring decades of environmental degradation and food relief. As an initial part of an effort to map and characterize key ecological resources at risk in Baringo, we interviewed 136 resident leaders from pastoral and agro-pastoral areas. We asked them to identify and rank their most vulnerable ecological resources, …

Public Engagement To Prioritize The Pastoral Research Agenda At The Pastoral And Agro-Pastoral Research Center Of Oari In Ethiopia, D. Layne Coppock, Getachew Gebru, Lemma Gizachew, Sintayehu Mesele, Mohammed Hassena, Solomon Desta

Environment and Society Faculty Publications

The Oromia Agricultural Research Institute (OARI) has a mandate to conduct agricultural and livestock research throughout the Regional State of Oromia in Ethiopia. OARI has recently opened a facility near Yabello town on the Borana Plateau called the Pastoral and Agro-Pastoral Research Center. A meeting was held in August 2006 at Yabello that involved representatives from pastoral communities, the private sector, government, and non-governmental organizations. The aim was to engage stakeholders in a process of problem prioritization and set the stage to create new partnerships to better address pressing problems. The final priorities included: addressing a general decline in forage …

Duty In Tort Law: An Economic Approach, Keith N. Hylton

Faculty Scholarship

Theories of tort law have focused on the breach and causation components of negligence, saying little if anything about duty. This paper provides a positive economic theory of duty doctrine. The theory that best explains duty doctrines in tort law is the same as the theory that explains strict liability doctrine. The core function of both sets of doctrines is to regulate the frequency or scale of activities that have substantial external effects. Strict liability aims to suppress or tax activities that carry unusually large external costs. Duty doctrines, especially those relieving actors of a duty of care, serve several …

The Fading Of Reported Effectiveness. A Meta-Analysis Of Randomised Controlled Trials, Bt Gehr, C Weiss, F Porzsolt

More Faculty of Health Research

Abstract Background The "real" effect size of a medical therapy is constant over time. In contrast, the effect size reported in randomised controlled trials (RCTs) may change over time because the sum of all kinds of bias influencing the reported effectiveness is not necessarily constant. As this would affect the validity of meta-analyses, we tested the hypothesis that the reported effect size decreases over time. Furthermore, we tested three hypotheses that would explain a possible change. Methods Because of well established outcome measures, the lipid-lowering drugs Pravastatin and Atorvastatin (serum low-density lipoprotein cholesterol, LDL-C) and the anti-glaucoma drugs Timolol and …

Working Toward Democracy: Thurgood Marshall And The Constitution Of Kenya, Mary L. Dudziak

Duke Law Journal

This Article is a work of transnational legal history. Drawing upon new research in foreign archives, it sheds new light on the life of Thurgood Marshall, exploring for the first time an episode that he cared very deeply about. his work with African nationalists on an independence constitution for Kenya. The story is paradoxical, for Marshall, a civil rights legend in America, would seek to protect the rights of white landholders in Kenya who had gained their land through discriminatory land laws, but were soon to lose political power. In order to understand why Marshall would take pride in entrenching …

Combined Effects Of Aldehyde Dehydrogenase Variants And Maternal Mitochondrial Genes On Alcohol Consumption, Yedy Israel, Maria E. Quintanilla, Amalia Sapag, Lutske Tampier

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Two lines of rats bred to differ in their voluntary alcohol consumption — the alcohol-abstaining UChA rats and the alcohol-drinking UChB rats — differ in how effectively toxic acetaldehyde is removed during alcohol metabolism. UChB animals carry efficient variants of the aldehyde dehydrogenase 2 (ALDH2) genes and have active mitochondria, resulting in fast removal of acetaldehyde. UChA animals, in contrast, carry less efficient ALDH2 variants and less active mitochondria, which result in transient elevations of acetaldehyde levels after alcohol ingestion. Cross-breeding studies have demonstrated that the presence of active mitochondria inherited from UChB females can fully abolish the reduction of …

Androgen-Regulated Formation And Degradation Of Gap Junctions In Androgen-Responsive Human Prostate Cancer Cells., Shalini Mitra, Lakshmanan Annamalai, Souvik Chakraborty, Kristen E. Johnson, Xiao-Hong Song, Surinder K. Batra, Parmender P. Mehta

Journal Articles: Biochemistry & Molecular Biology

The constituent proteins of gap junctions, called connexins (Cxs), have a short half-life. Despite this, the physiological stimuli that control the assembly of Cxs into gap junctions and their degradation have remained poorly understood. We show here that in androgen-responsive human prostate cancer cells, androgens control the expression level of Cx32-and hence the extent of gap junction formation-post-translationally. In the absence of androgens, a major fraction of Cx32 is degraded presumably by endoplasmic reticulum-associated degradation, whereas in their presence, this fraction is rescued from degradation. We also show that Cx32 and Cx43 degrade by a similar mechanism. Thus, androgens regulate …

Race-Conscious Student Assignment Plans: Balkanization, Integration, And Individualized Consideration, Neil S. Siegel

Duke Law Journal

In deciding Meredith v. Jefferson County Board of Education and Parents Involved in Community Schools v. Seattle School District No. 1, the Supreme Court of the United States will likely confront a critical issue to emerge from the lower court opinions on voluntary integration plans: whether school districts that use race as a factor in student assignment must comply with a legal requirement of individualized consideration. The Court has imposed such a requirement in other contexts, but it has not clearly explained what the concept of individualized consideration means and why particular forms of it matter.

The Proteomics Of N-Terminal Methionine Cleavage, Frédéric Frottin, Aude Martinez, Philippe Peynot, Sanghamitra Mitra, Richard C. Holz, Carmela Giglione, Thierry Meinnel

Chemistry Faculty Research and Publications

Methionine aminopeptidase (MAP) is a ubiquitous, essential enzyme involved in protein N-terminal methionine excision. According to the generally accepted cleavage rules for MAP, this enzyme cleaves all proteins with small side chains on the residue in the second position (P1′), but many exceptions are known. The substrate specificity of Escherichia coli MAP1 was studied in vitro with a large (>120) coherent array of peptides mimicking the natural substrates and kinetically analyzed in detail. Peptides with Val or Thr at P1′ were much less efficiently cleaved than those with Ala, Cys, Gly, Pro, or Ser in this position. Certain residues …
