Career Trajectories, Gender Differences And Accumulated Health Disparities Over The Life Course, Li Zheng

Theses and Dissertations

Using longitudinal data from Panel Study of Income and Dynamic (PSID) and multivariate analyses, this dissertation examines the dynamic and longitudinal relationship between gender, occupational career and health among people of working age under the new economy. The major concern is whether there are gender differences in the health returns to occupation/employment resources across life course, whether the gendered health gap diverges with age, and whether health affect men' and women's employment transitions and occupational mobility differently. Results show that women experience significantly poorer health than men, but this health gap reduces with aging. The health disadvantages experienced by women …

Comparison Of Student Achievement Among Two Science Laboratory Types: Traditional And Virtual, Mary Celeste Reese

Theses and Dissertations

Technology has changed almost every aspect of our daily lives. It is not surprising then that technology has made its way into the classroom. More and more educators are utilizing technological resources in creative ways with the intent to enhance learning, including using virtual laboratories in the sciences in place of the “traditional” science laboratories. This has generated much discussion as to the influence on student achievement when online learning replaces the face-toace contact between instructor and student. The purpose of this study was to discern differences in achievement of two laboratory instruction types: virtual laboratory and a traditional laboratory. …

Blanching Optimization And The Effect Of Blanching On Functional Components Of Yacon (Smallanthus Sonchifoulius) Root Slices, Yu-Ting Chen

Theses and Dissertations

Yacon (Smallanthus sonchifolius) root products are susceptible to oxidation, reduced quality and functional properties. The optimum water blanching process for yacon root slices was determined through a central composite design with variable temperature (80-100 degrees Celsius), blanching time (2-6 min), and citric acid concentration (0.04-0.20%). Phenolics and fructooligosaccharides of yacon slices were also evaluated after blanching. Yacon slices (3-4 mm) blanched at 90 degrees Celsius, 3.9 to 4.1min, and 0.05% to 0.07% citric acid showed the lowest polyphenol oxidase activity, highest whiteness value, and the highest sensory appearance scores. A second experiment showed that blanching at 100 degrees Celsius with …

Antioxidative And Antimicrobial Activity Of Casein Hydrolyzate In Cheddar Whey-Based Edible Coatings, Yin Zhang

Theses and Dissertations

Hydrolysis of casein using chymotrypsin results in the formation of polypeptides (CH) with a hydrophobic aromatic amino acid on one end of the chain because the enzyme selectively cleaves the adjacent peptide-bond. Due to resonance of the aromatic micro-domain, thiols become redox-sensitive and actively participate in electron transfer. These types of amphipathic peptides also tend to be membrane-lytic. The two prong approach of this investigation was to, (1) assess antibacterial effect of the CH in beef steak, and (2), to determine its antioxidative efficacy as a constituent of Cheddar whey based edible coating mix. The edible coating prevented coliform growth …

Validation Study Of A Novel Detection Kit For Rapid Detection And Quantification Of Listeria Spp. In Food Samples, Mengying Jiang

Theses and Dissertations

A single tube detection kit was designed as a rapid, easy-to use and reliable test to detect Listeria spp.. Various food samples (vegetables and raw catfish fillets) were used in order to validate the performance of the detection kit. L. grayi was detected in one ready-to-eat (RTE) vegetables with the detection kit while no Listeria spp. was detected using the modified FDA-BAM method. In addition, both the detection kit and modified FDA-BAM method indicated that twelve catfish fillets were Listeria positive. The detection kit had 100% sensitivity and specificity in less detection time (24 h) than the modified FDA-BAM method …

Influence Of Temperature On Acid-Stress Adaptation In Listeria Monocytogenes, Qian Shen

Theses and Dissertations

Acid-stress adaptation in Listeria monocytogenes (Lm) serotype 4b and 1/2a occurred when cells were pre-exposed to pH 5.0 tryptic soy broth supplemented with yeast extract (TSB-YE) at 22°C or 37°C but not at 4°C. Prolonged time, varied sublethal acid pH, substitute of acidulants and addition of sodium chloride during 4°C mild acid pre-exposure still did not induce acid-stress adaptation in Lm. This finding was also validated using an acidic cheese, similar to what has seen for Gram-negative bacteria E. coli and Salmonella. Further investigation revealed that major cold shock protein in Lm CspL was not responsible for repressed acid-stress adaptation …

Influence Of Temperature On The Induction Of Alkali-Stress Adaptation And Its Stability In Listeria Monocytogenes Serotypes 1/2a And 4b, Pooja Pandare

Theses and Dissertations

The purpose of this study is to determine the effect of temperature on inducing an alkaline-tolerance response in L. monocytogenes (Lm) serotypes 1/2a and 4b. When Lm cells were pre-exposed to a sublethal alkali pH of 9.0 at different temperatures, two main patterns were observed: (1) Alkali-stress adaptation was readily induced in Lm when cells were pre-exposed to a sublethal alkali pH of 9.0 for 5-15 min at 37°C or 22°C; and (2) Alkali-stress adaptation was not induced in Lm when cells were pre-exposed to a sublethal alkali pH of 9.0 for 1 h at 4°C. However, exposure of Lm …

Allostatic Load Amplifies The Effect Of Blood Lead Levels On Elevated Blood Pressure Among Middle-Aged U.S. Adults: A Cross-Sectional Study, Ami R. Zota, Edmond R. Shenassa, Rachel Morello-Frosch

Environmental and Occupational Health Faculty Publications

Background

Scientists and regulators have sought to understand whether and how physiologic dysregulation due to chronic stress exposure may enhance vulnerability to the adverse health effects of toxicant exposures. We conducted a cross-sectional study to determine whether allostatic load (AL), a composite measure of physiologic response to chronic exposure to stress, amplifies the effect of lead exposure on blood pressure among middle-aged adults.

Methods

We analyzed associations between blood lead levels and blood pressure in a nationally representative sample of 8,194 U.S. adults (aged 40-65 years) participating in the National Health and Nutritional Examination Survey, 1999--2008. Outcomes were elevated systolic …

Dose- And Time-Dependent Neuroprotective Effects Of Pycnogenol® Following Traumatic Brain Injury, Mubeen A. Ansari, Kelly N. Roberts, Stephen W. Scheff

Sanders-Brown Center on Aging Faculty Publications

After traumatic brain injury (TBI), both primary and secondary injury cascades are initiated, leading to neuronal death and cognitive dysfunction. We have previously shown that the combinational bioflavonoid, Pycnogenol® (PYC), alters some secondary injury cascades and protects synaptic proteins when administered immediately following trauma. The purpose of the present study was to explore further the beneficial effects of PYC and to test whether it can be used in a more clinically relevant fashion. Young adult male Sprague-Dawley rats were subjected to a unilateral moderate/severe cortical contusion. Subjects received a single intravenous (i.v.) injection of PYC (1, 5, or 10 mg/kg) …

Survey Of Mycorrhizal Colonization In Native, Open-Pollinated And Introduced, Hybrid Maize In Villages Of Chiquimula, Guatemala, Jessica Hess, Dr. Von D. Jolley

Journal of Undergraduate Research

Mycorrhizae is a symbiotic association between certain species of soil fungi and the root systems of many land plants. Most economically important crops form this association. By colonizing plant roots, mycorrhizal fungi receive a carbon supply from photosynthesis in plant tissues. The plant, by reason of the fine, extracellular, hyphal network of the fungi, is lent a greatly improved access to soil nutrients (especially phosphorus), improves its water relations, and may receive some resistance to soil-borne diseases. Some scientists assert that optimal management of mycorrhizae is an essential part of sustainable agricultural systems (1).

Modified Á-Zeins Containing Lysine Inserts Will Interact With Ã-Zeins To Form Stable Protein Bodies In Transgenic Tobacco Endosperm, James Bird, Dr. Craig E. Coleman

Journal of Undergraduate Research

Maize is one of the most abundantly produced grains on earth and is widely used in human and livestock diets. 90% of maize protein is found in the endosperm portion of the seed in the form of small spherical aggregates called protein bodies. These protein bodies consist of four structurally distinct alcohol soluble proteins called á-, â-, ã-, and ä-zeins.1 Initial stages of protein body formation involve â- and ãzeins forming spherical accretions which later enlarge by the accumulation of á-zeins inside the â- and ãzein spheres.2 á-Zeins alone constitute 70% of the protein body and therefore make up a …

Bone Density In College Women: The First Phase Of A Two Phase Study Of The Early, Modifiable Markers Of Osteoporosis And The Effect Of Calcium And Magnesium Supplements, Jason Boyd, Dr. Bruce H. Woolley

Journal of Undergraduate Research

Peak bone mass of pre-menopausal women has been established as a major risk factor for postmenopausal osteoporosis and related bone fractures (4). Previous research evidence suggest that bone mass of both the peripheral and axial skeleton is stable for women before menopause (1,2). Teegarden et al.(3) established that peak Bone Mineral Content (BMC) is attained by age 26.2+/- 3.7 years. After peak BMC is obtained, mass of cortical and trabecular bone and BMC will decline at a rate of approximately 1.2% per year.

Value Blueprint And Service Design Space For Facilitating Value Creation, Steven Alter

Business Analytics and Information Systems

A new operational perspective on fundamental concepts related to customers, service, and value differs from service-dominant logic in its approach to service systems, value creation, value co-creation, service interactions, value facilitation, and value constellations. This perspective leads to two new tools for supporting service system design: 1) A “value blueprint” uses a swimlane representation to identify where value creation occurs, recognizing that parts of value creation may occur long after service providers have produced their contributions to customer value. 2) A multidimensional design space for value facilitation identifies design dimensions that can be used for characterizing current or proposed approaches …

Type 1 Diabetes And The Male Reproductive Axis, Erica Schoeller

Arts & Sciences Graduate Student Theses and Dissertations

Glucose regulation is important in both spermatogenesis as well as mature sperm function. The impact of diabetes on sperm function is becoming increasingly clear, though much work is still needed to elucidate the mechanism by which diabetes impairs spermatogenesis. Diabetes causes disruptions in the hypothalamic pituitary gonadal (HPG) axis, the regulatory system that controls reproduction. The HPG axis functions by secreting GnRH pulses from the hypothalamus, which bind to receptors on the pituitary and cause secretion of follicle stimulating hormone and luteinizing hormone, which then bind to receptors in the testes and facilitate spermatogenesis. Type 1 diabetes can severely impact …

Post-Translational Regulation Of Fas-Mediated Pparα Activation, Anne Patricia Louise Jensen-Urstad

Arts & Sciences Graduate Student Theses and Dissertations

The liver is a central organ to whole-body metabolism and mediates many of the adaptive responses to changes in nutrient availability, such that the appropriate energy sources are used and blood glucose levels maintained, whether directly after a meal or after a twelve-hour fast. The adaptive responses to fasting in liver are largely mediated by the nuclear receptor peroxisome proliferator-activated receptor α, or PPARα. PPARα can be activated by a de novo synthesized lipid ligand—16:0/18:1- glycerophosphocholine (16:0/18:1-GPC)—the synthesis of which is dependent on fatty acid synthase (FAS), but little is known about the regulation of this pathway. My thesis focused …

Articles

Background

Acrylamide as a possible carcinogen is known to form in heated carbohydrate-rich food such as potato chips. In this study, the effect of three potato varieties (Agria, Sante and Savalan) and two blanching conditions ((75˚C for 9 min and 83˚C for 2.5 min) on the concentration of precursors and acrylamide reduction in potato chips was investigated.

Results

Results revealed that potato variety and blanching time-temperature ere important parameters for acrylamide formation in potato chips. Acrylamide content in Sante variety potatoes, which contained the highest amount of reducing sugars, was found to be the highest (8825μg/kg). However, Savalan, containing …

Effectiveness Of An Information-Motivation-Behavioral Skills – Based Educational Intervention To Promote Gardasil Use Among Female Undergraduate Students, Giselle K. Perez Lougee

Doctoral Dissertations

Cervical cancer is a virally mediated disease with the majority of cases due to the human papillomavirus (HPV). HPV infections are the most prominent sexually transmitted diseases among college-aged women. Although HPV vaccines such as Gardasil afford women with a valuable method of cancer prevention, vaccination rates are often incomplete or inadequate. This study evaluated the effectiveness of an interactive, information-motivation-behavioral skills (IMB) based, multimodal program to promote Gardasil use among 62 undergraduate women enrolled at the University of Connecticut. Secondary aims targeted additional health behaviors, including risky sexual practices and Pap Screen utilization. Participants were randomly assigned to a …

Brand Kerala: Commodification Of Open Source Ayurveda, Chithprabha Kudlu

All Theses and Dissertations (ETDs)

This dissertation aimed to understand formal and informal ayurvedic knowledge and practice through the framework of commodification, in the context of the recent emergence of global ayurvedic tourism in Kerala, India. The objective was to understand how commodification, both old and new, have affected knowledges and livelihoods of actors constituting the ayurvedic commodity chain, with a focus on `social lives' of ayurvedic pharmaceuticals and select herb-ingredients. I argue that the trajectory of commodification in Kerala provides a stark contrast to the national mainstream with its focus on classical vis-à-vis proprietary medicines. This therapy-centric business model maintained the integrity of traditional …

Social Capital And Walkability As Social Aspects Of Sustainability, Shannon H. Rogers, Kevin H. Gardner, Cynthia H. Carlson

Civil & Environmental Engineering

The concepts of sustainability and sustainable development are frequently described as having three main components, sometimes referred to as the three pillars or the triple bottom line: environmental, economic, and social. Because of an historical focus in the sustainability field on correcting environmental problems, much consideration has been given to environmental issues, especially how they interface with economic ones. Frequently mentioned but rarely examined, the social aspects of sustainability have been considered the weakest and least described pillar. After a brief review of existing concepts and theories, this paper uses a case study approach to examine the third pillar more …
