Residential Recycling Study, Richard Adams

Open Access Theses & Dissertations

The purpose of this study is to gain baseline performance figures and statistics for El Paso's curbside recycling program. With these baseline statistics the effectiveness of changes for promotion and outreach can be evaluated once implemented. In addition, operational changes such as to every other week recycling collection rather then every week or a "pay as you throw" system could be evaluated.

Drowning In The Depths Of Climate Change: An Exploration Of Polar Bear Rhetoric, Gloria Leticia Bebber

Open Access Theses & Dissertations

This study explored campaigns that used polar bears to bring awareness to the issue climate change. The study analyzed three environmental campaigns, two major corporations, and one non-profit organization. The campaigns were examined using a rhetorical criticism method. Findings show that although polar bears are symbolically a good representation of the effects of climate change, it is imperative to address the entire issue. The limitations that occurred during the study are addressed.

Altered Leptin Signaling On Dendritic Cells As A Potential Mechanism For Cancer Immunotherapy, Lorena Y. De Los Santos

Open Access Theses & Dissertations

Leptin is a pleiotropic hormone synthesized primarily by white adipocytes and its receptors are expressed in a variety of tissues and cells such as in the hypothalamus and cells of the immune system. Multiple cell types can produce a considerable amount of leptin such as skeletal muscle, placenta, and osteoblasts to name a few and its synthesis has been shown to be regulated by sex hormones and a broad range of inflammatory mediators. Although leptin has been shown to directly affect immune response, we are interested in how leptin affects dendritic cell function and their ability to induce a proper …

Incorporating Sustainability Into Urban Infrastructures: The Tension Between Bio-Cultural Aspects And Environmental Considerations, Shane Epting

Open Access Theses & Dissertations

The following arguments focus on how to think about sustainability as it relates to technology and the non-human world within an anthropocentric framework. We end up with a picture showing that humankind needs to change the ways in which we look at anthropocentric concerns. Secondly, the discussion that leads up to the final picture details the urgency that guides the thinking behind the implementation of sustainability. Because, as the West learns to live in an entirely new sense that is consistent with holding humankind's desire for existence as a permanent situation, one finds that this notion must be paramount for …

Comparison Of Two Environmental Health Education Methods To Reduce Exposure To Residential Pesticides In Hispanic, Patricia M. Juarez-Carrillo

Open Access Theses & Dissertations

ABSTRACT

Exposure to pesticides is associated with adverse health outcomes including poisonings, short-term signs and symptoms, and long-term adverse health outcomes including developmental and cognitive impairments, certain types of cancer, and damages to the endocrine, nervous, and reproductive systems. This study tested two educational methods aimed to help Hispanic, Spanish-speaking mothers living in the U.S.-México border make informed decisions about pesticides applied in their homes. 230 women were randomly allocated to a) a small group talk, b) a graphic booklet, or c) a control group. The outcomes were the knowledge level about the risks of pesticides and the pest prevention …

Bioprinting Oxygen Releasing Microparticles For Improved Cell Tissue Viability, Daniel Reyna

Open Access Theses & Dissertations

A major challenge in regenerative medicine/tissue engineering is the difficulty of providing adequate oxygen to all cells within implanted engineered tissues before full vascularization is achieved. To overcome this limitation, a variety of oxygen-releasing particles have been developed to improve cell and tissue survival. However, most of these particles are used in random mixtures within scaffolding materials, which usually leads to an uneven distribution of oxygen in bioengineered tissues. An ideal oxygen supply requires a precise depositing control of oxygen-releasing particles in scaffolds. Cell bioprinting is a novel tissue fabrication approach, in which the bio-printer can be programmed to deposit …

Assessment Of Intra-Urban Traffic-Related Air Pollution On Asthmatic Children's Exposure At Schools In The Paso Del Norte Region, Amit Ugamraj Raysoni

Open Access Theses & Dissertations

Traffic-related air pollution can be a major public health concern in any urban area. This problem is compounded in the Paso del Norte region that has experienced rapid economic growth, and a substantial number of people living in close vicinity of major roadways. The desert surroundings, arid weather, frequent temperature inversions, heavy border traffic at the international ports of entry between El Paso and Ciudad Juárez, and poorly maintained vehicle fleet further exacerbates this problem. A growing body of air quality and epidemiologic research has discerned the linkage between traffic emissions and respiratory disorders.

Initial health investigations in the Paso …

The Role Of Perceptual Processes In The Use Of And Willingness To Use Professional Health Care Services, Luis Omar Rivera

Open Access Theses & Dissertations

To better address ethnic health disparities, it is imperative that we understand the psychological processes that shape people's use of and willingness to use professional health care services. The current research proposes and tests a model in which people's attentional orientation toward context discourages them from seeking professional health care services because (a) attentional orientation toward context encourages people to attribute symptoms of illness to external/environmental factors and (b) attributing symptoms of illness to external/environmental factors is associated with less use of professional health care services. The results of two studies show mixed support for the proposed model. Consistent with …

The Role Of Cross-Language Activation In Syntactic Ambiguity, Li-Hao Yeh

Open Access Theses & Dissertations

There is much evidence demonstrating that bilinguals activate lexical representations from both of their languages in a non-selective manner even in sentence context. Comparatively less research has examined the extent to which bilingual lexical representations interacts with syntactic processing in sentence context. The purpose of this study is to examine whether bilinguals' cross-language lexical activation could influence their resolution of syntactic ambiguity (e.g. relative clause attachment). Proper attachment of relative clauses (RC) to noun phrases is critical for accurate interpretation of syntactically ambiguous sentences. For instance, the sentence The robber shot the secretary of my husband who goes to work …

Solutions And Open Challenges For The Symbol Grounding Problem, A Cangelosi

School of Engineering, Computing and Mathematics

This article discusses the current progress and solutions to the symbol grounding problem and specifically identifies which aspects of the problem have been addressed and issues and scientific challenges that still require investigation. In particular, the paper suggests that of the various aspects of the symbol grounding problem, the transition from indexical representations to symbol-symbol relationships requires the most research. This analysis initiated a debate and solicited commentaries from experts in the field to gather consensus on progress and achievements and identify the challenges still open in the symbol grounding problem.

Antioxidant And Antihypertensive Activities Of Rice Bran Peptides, Janika Hull, Arvind Kannan, Navam S. Hettiarachchy

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Protein isolates and peptide fractions from food sources (cereal grains), have been shown to exert bioactive properties including antiobesity, anticancer, antiangiogenic, etc. One such food source is rice bran, which is an underutilized co-product of rough rice milling. It contains 90% of the nutrients and nutraceuticals of value to health, including high quality protein. The high quality protein is a potential source to generate peptides that can reduce hypertension and oxidative stress, both being important risk factors for cardiovascular diseases. The objective of this study was to extract peptide hydrolysates from heat stabilized defatted rice bran by enzymatic hydrolysis, evaluate …
