Beliefs And Perceptions Of Millennials Pertaining To Climate Change And Sustainability, Rae Cade

Theses, Dissertations and Culminating Projects

The purpose of this qualitative multi-case study is to explore the beliefs and perceptions of millennials on the subjects of climate change and sustainability. Some millennials pursuing an undergraduate degree in a non-environmental science field may lack knowledge pertaining to climate change and sustainability. The conceptual framework for this qualitative explanatory multi-case study is grounded in contributions from Henri Lefebvre, Nicholson-Smith (1991), and Simpson (2014) who explore how the notion of space has evolved in recent years, as well as researchers who are quantitatively studying climate change and sustainability. I conducted semistructured focus groups and drafted field notes from two …

Estimating Parasitoid Wasp Assemblages On Fragmented Land : Do Habitat And Trap Type Matter?, Matthew Charles Christopher Havers

Theses, Dissertations and Culminating Projects

Parasitoid wasps are a hyper-diverse monophyletic group of Apocrita (Hymenoptera) that typically oviposit inside or on an arthropodal host, whereafter the wasp larvae obtain nutritional resources for development. Although some species are well-studied as agents in biological control, little is known about the biology of the less diverse and less abundant superfamilies; and even less about assemblages of parasitoid wasp taxa within a given habitat. The aim of the present study was twofold: to estimate parasitoid wasp assemblages within two habitats common in central and northern New Jersey, USA, and to develop a protocol to increase the yield and diversity …

Housing Stability And Diabetes Among People Living In New York City Public Housing, Sungwoo Lim, Sze Yan Liu, Melanie H. Jacobson, Eugenie Poirot, Aldo Crossa, Sean Locke, Jennifer Brite, Elizabeth Hamby, Zinzi Bailey, Stephanie Farquhar

Department of Public Health Scholarship and Creative Works

Public housing provides affordable housing and, potentially, housing stability for low-income families. Housing stability may be associated with lower incidence or prevalence and better management of a range of health conditions through many mechanisms. We aimed to test the hypotheses that public housing residency is associated with both housing stability and reduced risk of diabetes incidence, and the relationship between public housing and diabetes risk varies by levels of housing stability. Using 2004-16 World Trade Center Health Registry data, we compared outcomes (housing stability measured by sequence analysis of addresses, self-reported diabetes diagnoses) between 730 New York City public housing …

Life History And Metabolic Responses Of Daphnia Magna Exposed To Effluents Of Urban Origin Treated By Advanced Oxidation, Benjamin Z. Szczygiel

Biology Theses

Modern sewage treatment processes do not remove many chemicals that pass through the sewer system, including pharmaceuticals and personal care products that have been shown to have negative effects in ecosystems. New processes have been developed to remove these chemicals, known as advanced oxidation processes (AOPs). In this study, Daphnia magna are used to examine the effects of wastewater effluent treated conventionally compared to effluent treated with AOPs (Peracetic Acid/Ultraviolet Light and Hydrogen Peroxide/Ultraviolet Light). For this purpose, two sets of experiments were preformed: a five-day survivorship trial, and a 14-day life history experiment. Growth, survival, and reproduction of Daphnia …

Black soldier fly (BSF) (Hermetia illucens L.) is one of the most efficient bio-waste recyclers. Although, waste substrate amendments with biochar or gypsum during composting process are known to enhance nutrient retention, their impact on agro-industrial waste have not been documented. Hence, this study focuses on a comparative effect of agro-industrial waste amended with biochar and gypsum on BSF larval performance, waste degradation, and nitrogen (N) and potassium retention in frass fertilizer. Brewery spent grain was amended with biochar or gypsum at 0, 5, 10, 15 and 20% to determine the most effective rates of inclusion. Amending feedstock with 20% …

Role Of Cyp2b6 In Perfluorooctanesulfonic Acid (Pfos)-Induced Toxicity And Non Alcoholic Fatty Liver Disease (Nafld), Matthew C. Hamilton

All Theses

Perfluorooctanesulfonic acid (PFOS) is a persistent, toxic fluorosurfactant foam used in firefighting foams, textiles, and other industrial products. Human CYP2B6 is predominantly expressed in the liver and responsible for metabolizing xeno- and endobiotics. CYP2B is induced by PFOS and high-fat diets in rodents and therefore it was hypothesized that CYP2B contributed to PFOS-induced steatosis. Cyp2b-9/10/13-null (Cyp2b-null) and humanized CYP2B6-Tg (hCYP2B6-Tg) mice were treated with PFOS (0, 1, or 10 mg/kg/day) by oral gavage in mice fed either a typical chow diet (ND) or a high-fat diet (HFD). Our studies show human CYP2B6 is also inducible in vivo by PFOS. In …

Creating A Quality Improvement Toolkit To Identify & Address Gaps In The Care Of Older Adults With Hip Fracture, Amanda J. Covell

Doctoral Projects

Introduction: Traumatic hip fracture remains a major cause of disability, decline, and mortality for adults over 65. Gaps remain in the consistency of care and services hip fracture patients receive during hospitalization and post-discharge, leading to adverse outcomes, including MI, surgical site infection, poorly managed pain, and increased mortality. To help address these inconsistencies, the AAOS released updated clinical practice guidelines for management of hip fracture care in the elderly in 2014. These guidelines examine the entire hospitalization process for this population and set forth evidence-based standards to assist with improving outcomes for hip fracture patients.

Video Education For Improved Education Of Newly Diagnosed Multiple Sclerosis Patients, Theresa Mccrumb

Doctoral Projects

Anxiety and depression are prevalent in multiple sclerosis (MS) patients, especially those newly diagnosed. Receiving a diagnosis of MS can be overwhelming and impact patients in multiple areas including physical issues, cognitive changes and anxiety and depression (Kantor, Bright & Burtchell, 2017). This anxiety and depression can cause patients to be less engaged in their plan of care and thereby reduce their quality of life (Rieckmann, et al., 2015). According to the Multiple Sclerosis Association of America (MSAA), four of 10 MS patients are diagnosed with depression and anxiety, with the highest incidence at diagnosis (Multiple Sclerosis Association of America, …

From The Dinner Pot To Smoking Pot; How A Better Understanding Of Cannabidiol In Crayfish Could Alleviate Anxiety And Modulate Hunger, Christopher Michael Timmer

Masters Theses

Anxiety affects approximately 1/3 of the US population and presents in many different forms, ranging from social to panic disorders. It also presents with high comorbidity for other mental disorders. One treatment is Selective Serotonin Reuptake Inhibitors (SSRIs) which allow for increased activation of serotonin (5-HT) receptors. SSRIs come with an extensive list of side effects, which can fail to maintain quality of life. Cannabidiol (CBD) is a cannabis derived compound which has been shown to decrease anxiety by activation of multiple subtype 5-HT amine receptors. CBD has few side effects, is not psychoactive, and exhibits anti-psychotic properties. The current …

Local Food Prices And The Purchasing Power Of Snap Benefits, G. Christensen, Erin Todd Bronchetti

Economics Faculty Works

While the nominal value of Supplemental Nutrition Assistance Program (SNAP) benefits is fixed across states (except for Hawaii and Alaska), variation in food prices across the U.S. is dramatic. We provide new evidence describing geographic variation in the purchasing power of SNAP benefits, measured by the extent to which SNAP-recipient households are able to afford the Thrifty Food Plan (TFP), the U.S. Department of Agriculture (USDA) food plan on which legislated SNAP benefit levels are based. For more than one-quarter of SNAP households, SNAP benefits are too low to cover the cost of the TFP at the primary stores where …

Genes Involved In Nitrogen Assimilation In Ustilago Maydis., Sunita Khanal

Electronic Theses and Dissertations

U. maydis can utilize nitrate as a source of nitrogen from its environment, a process requiring a nitrate transporter to bring the nitrate inside the cell. This is followed by a two-step reduction of nitrate to ammonium. At first, nitrate reductase reduces nitrate into nitrite; in the second reaction, nitrite is reduced to ammonium by nitrite reductase. The goal of the study was to identify the nitrate transporter and nitrite reductase genes in U. maydis and characterize them based on their role in mating and virulence. The genes um03848 and um03849 were identified bioinformatically as encoding, respectively, the nitrite reductase …
