Rare's Implementation Strategies Of Environmental Conservation In Indonesia, Alvaro Arvizo

Open Access Theses & Dissertations

Like most developing nations, Indonesia is at a crucial stage in its modern political and economic history. Opposing forces are constantly at work, a government struggling to make Indonesia a modern nation and the economic demands of a growing population. This presents the country with a multitude of problems. One of several is that nature's resources are exploited for personal economic gain with no regard for the long-term effects. This is a major concern for environmental conservation and non-profit government organizations (NGOs) worldwide. The American NGO Rare is at the forefront of this issue. Its aim is to meet community …

All The Things I'Ve Been, Richard Helmling

Open Access Theses & Dissertations

In The Postmodern Condition, Lyotard identifies narrative as a distinct type of knowledge created and reshaped by individuals as nodal points. The novel All the Things I've Been explores this paradigm in Postmodern thought by following a narrator disconnected from ostensible reality as he attempts to create a new explanatory narrative to excuse his own misdeeds. Living in a subterranean hole, he draws on elements of the literature he hoards about him to construct a plot that will account for a past he is unwilling or unable to confront.

El Paso, Texas, And Ciudad Juarez, Chihuahua, 1880-1930: A Material Culture Study Of Borderlands Interdependency, Gladys Arlene Hodges

Open Access Theses & Dissertations

ABSTRACT

Material culture theory informs this study of urban history and borderlands interdependency at El Paso, Texas, and Ciudad Juárez, Chihuahua, Mexico, from 1880-1930. Features incised into and structures built onto the natural environment by the first arriving colonists after the mid-seventeenth century endured for more than two centuries. Over that period, the humanly-created material environment, a social product, fed back into the development of social forms--institutions, rituals, practices, modes of interaction, activities, and beliefs. A significant number of these social forms endured into the late nineteenth century and beyond, even after mechanization and industrialization arrived in the region known …

Hydrological Characteristics Of A Large-Scale Flooding And Draining Experiment, Barrow, Alaska, Edith Jaurrieta De Velasco

Open Access Theses & Dissertations

The Arctic appears to be affected by climate change more so than any other region on Earth. Some of the most significant climate change impacts reported for the Arctic are associated with dramatic shifts in the hydrologic regime of terrestrial ecosystems. Understanding the hydrologic processes that are associated with different components of arctic terrestrial ecosystems is important because water in the form of snow or rain influences a range of properties and processes such as land-atmosphere energy and trace gas fluxes, nutrient cycling, ecosystem dynamics, biodiversity, periglacial processes and surface albedo. Furthermore, plants, animals, and native people of the Arctic …

Optimization Models For The Economic And Non-Economic Level Of Repair Analysis, Carlos Marco Ituarte-Villarreal

Open Access Theses & Dissertations

Every component, equipment or system will eventually fail. All failures produce a maintenance cost and, repair costs are especially hard to estimate ahead of time. Research shows that maintenance costs are the most substantial costs of development and use of equipment, reason why the cost of the product or equipment through its life is a major concern. Therefore, the main objective of this thesis is to provide a new optimization model to determine the minimum cost maintenance policy for complex systems.

Study Of Pbdes In Wastewater, Water And Sludge Of El Paso Del Norte Border Region Using Sbse Td/Gc-Ms, Beatriz Adriana Rocha-Gutierrez

Open Access Theses & Dissertations

Polybrominated diphenyl ethers (PBDEs) are a group of brominated compounds widely used as flame retardants. PBDEs are structurally similar to polychlorinated biphenyls (PCBs), and appear to act similarly in the environment. Due to their persistence and lipophilicity, PBDEs are found to be bioaccumulated and biomagnified in the food chain. Current research in PBDEs is focused on their occurrences, concentration, fate and transport in the environment, and the impact in the ecosystem and human health. Since PBDEs are not regulated in the USA, large amounts of these harmful chemicals are being dumped indiscriminately into the drainage system. As a result, these …

Preliminary Archaeological Investigations At The Sierra Diablo Cave Site: Paleoindian And Archaic Occupations In Hudspeth County, Texas, Jose Javier Vasquez

Open Access Theses & Dissertations

It is generally rare to find archaeological sites in the Southwest that retain the type of contextual integrity that the Sierra Diablo Cave exhibits. Often times, cave sites such as the one currently studied offer excellent preservation of cultural materials due to the general lack of moisture and isolation from wind and water erosion. The research aimed to determine when the site was occupied as well as the types of activities that were occurring during those occupations. It exhibits an extensive stratigraphic sequence that contains a well pronounced Late Archaic Period assemblage (Strata A and B) and a Late Pleistocene/Early …

Systematics Of The Genus Ptychadena Boulenger, 1917 (Anura: Ptychadenidae) From Democratic Republic Of The Congo, Katrina Marie Weber

Open Access Theses & Dissertations

This thesis increases the scope of previous phylogenetic analyses that revealed high levels of genetic differentiation within the anuran genus Ptychadena. Herein, I increase sampling of Central African populations of Ptychadena by over six times to examine their relationships to other African populations and to search for cryptic species. This study represents the most comprehensive molecular phylogeny of Ptychadena to date. A total of three mitochondrial (12S, 16S, and cyt b) and two nuclear (RAG1 and rhodopsin) genes were sequenced for 67 specimens of Ptychadena. Maximum parsimony, maximum likelihood, and Bayesian analyses were conducted. These analyses revealed …

Using Soil-Borne Polycyclic Aromatic Hydrocarbons (Pahs) And Organic Carbon In Soil For Projecting Pollution States Of Pahs In Ambient Air, Chika Yamaguchi

Open Access Theses & Dissertations

Polycyclic Aromatic Hydrocarbons (PAHs) are of environmental concern due to their ubiquitous nature, long-range transport, long half-lives, and toxicity. PAHs enter the environment as a consequence of incomplete combustion and cause adverse health effects. Because they are omnipresent pollutants, PAH distribution is not only a local issue, but also a global issue. Therefore, monitoring PAHs in ambient air and identifying their sources and distribution patterns have tremendous importance in assessing public health. However, sampling and analyzing airborne PAHs with conventional methods is time consuming and costly. In addition, an active sampling method remains unfeasible in many cases because it requires …

The Use Of Social Marketing As A Means Of Promoting Enviornmental Conservation: A Case Study Of Indonesian Biodiversity Campaigns, Alesia Za Gara

Open Access Theses & Dissertations

As a means of preserving Indonesia's natural allure and resources it is evident that there must be a conscious shift made wherein environmental conservation becomes top priority among the people of Indonesia and the world. Traditionally dealt with through a country's governmental facets, a new tread of social marketing is now being employed ENGOs in various countries such as Indonesia as a way to promote biodiversity conservation. For example, one such ENGO is Rare Conservation, an international organization that teaches social marketing tools to classes or cohorts of individuals around the world as a means of improving a variety of …

Observer-Dependent Model For Analyzing Subjective Parameters In Epidemiology, Milad Zarei

Open Access Theses & Dissertations

Although medical technologies for preventing the contagion and spread of infectious diseases have improved steadily throughout the last century, new infectious diseases are still emerging and spreading swiftly. The modeling of infectious disease spread is crucial in addressing the lack of predictive ability in epidemiology. Managing the spread of infectious diseases requires processing quantitative epidemiological data and the ability to capture the dynamics of the infectious disease in order to provide a measure of control.

In this thesis, I have introducing cognitive biases in diseases spread modeling. For the first time, to the author's knowledge, the human subjective experience has …

Atopy In Us-Mexico Border Elementary School Children: A Pilot Study, Julia Laura Alvarez

Open Access Theses & Dissertations

Background and Significance. Atopy is a hypersensitivity disorder that mainly affects the mucous membranes and the skin. It is reported to be the most prevalent type of clinical allergy syndrome. Persons who have atopy suffer from various combinations of asthma, rhino-conjunctivitis and/or eczema. Atopy is defined as an inherited predisposition to generate IgE against common environmental allergens. Atopy is a type I hypersensitivity condition mediated by IgE immune response, while allergy is any excessive immune response to a foreign antigen. Thus, all atopic disorders are allergic response but some allergic conditions are not atopic per se.

Identifying Influential Observations Through The Intraclass Correlation Coefficient, Angel De Jesus Davalos

Open Access Theses & Dissertations

In this thesis, we analyze the performance of adapting the DFBETA statistic for identifying influential observations on the intraclass correlation coefficient under the assumptions of the one-way random effects model. Additionally, we introduce an approach for transforming negative intraclass correlation coefficient estimation values using the method of moments estimator. We apply this method on a data set of repeated blood pressure measurements, after which we will investigate implications of identifying influential observations.

Causation And Circularity In Dispositionalism, Daniel Jacob Flores

Open Access Theses & Dissertations

I wish to present a narrow discussion of Bird's and Mumford's basic positions on their versions of dispositionalism. I think that they are correct to point to the threat of circularity and regress but I do not believe that they have successfully argued away the problem. I begin by offering a very brief account of dispositions and three general criticisms. The goal is to show that causation is central to a satisfactory account of dispositionalism. Next, I outline Mumford's and then Bird's general positions on dispositions. What this will show is the importance of the regress/circularity objection. Both philosophers understand …

The Sunk Cost Fallacy And Individual Differences In Health Decisions, Norma P. Fernandez

Open Access Theses & Dissertations

The Sunk Cost fallacy is a biased committed when individuals base their decisions to stop or continue a course of action solely on past irrecoverable invested costs (i.e., monetary or time-related). Individuals' susceptibility to the Sunk Cost fallacy has been justified as the need to try to avoid appearing wasteful, to avoid appearing inconsistent, to learn a lesson from and to punish self for a poorly made decision. A study by Bornstein and Chapman (1995) evaluated these justifications along with a normative response and found statistical differences among all justifications. However, the study of the Sunk Cost fallacy and these …

Ganglioside-Cytokine Interaction In The Induction Of Primary Brain Cell Death, John Charles Gorbet

Open Access Theses & Dissertations

Gangliosides have been implicated in multiple pathologies affecting the central nervous system (CNS) and recent research has implicated them in playing an active role in the pathogenesis of multiple sclerosis. Empirical studies and theoretical considerations have suggested the possibility of interactions between gangliosides, like GD3, and pro-inflammatory cytokines present in the nervous system. This study sought to investigate the possibility that either individual gangliosides acting alone or complexed with other species interact with the known immune response factor TNF&alpha to initiate or facilitate cell death in the CNS. I examined the cellular viability and gene expression in primary brain cell …

Developmental Variation In Children's Acquisition Of Metrical Structure: How Early Treatment Of Stressless Syllables Can Inform Phonological Theory, Clifford S. Jones

Open Access Theses & Dissertations

The present study uses 26 color photos to elicit a total of 14 words conforming to a very specific pattern: a stressless syllable word-initially, followed by a stressed syllable, and at most one more stressless syllable. This was found to be a particularly difficult metrical structure for the two- and three-year old participants to produce in an adult-like manner. Based on the findings that a fairly reliable (if language-particular) order of acquisition is observable for contrasts of both place and manner of articulation, the case is made for a system of six emergent features, which may be characterized as combinable …

Open Access Theses & Dissertations

Ti-6Al-4V lattice block structures manufactured through the electron beam melting (EBM) process are a promising field in design and research due to great advantages that the alloy, the process and the final product offer. Three lattice block structures were manufactured through the electron beam process using an ARCAM A2 machine. The structures were designed using the MATERIALIZE^TM software and were designed around different types of unit cells. Compression testing was performed and one unit cell was selected due to its anisotropic behavior for modified impact testing. The same unit cell was used and it was scaled up to add …

The Literary Fictioning Of John Gregory Bourke's Imperial Nostalgia, Toni K. Mcnair

Open Access Theses & Dissertations

Nineteenth-century Army Captain and American ethnographer John Gregory Bourke (b. 1846 - d. 1896) meticulously described and documented a vast amount of information on military life, geography, ecology, and people on both sides of the Mexican-American border, offering observations and opinions of American, Mexican, Mexican-American, Apache, Pueblo, Zuni and Plains Indian cultures. Because of his ethnographic studies of Mexican-Americans along the Rio Grande, cultural studies scholars, José E. Limón and José David Saldí­var have identified John Gregory Bourke as complicit in the U.S. government's imperialist project. Referring to Renato Rosaldo's anthropological theory of imperialist nostalgia, These authors declare Bourke's work …

The temperature coefficient of metabolism (Q10) averaged 2.8 between temperatures of 20°-30°C and 2.15 …

Embodied Cognition As Refutation To Langer's "Illusory Powers": "I Move, Therefore, I Know", Ruby Amanda Montana

Open Access Theses & Dissertations

Thesis Objective: To refute Susanne Langer's notion within her philosophy of dance which holds that emotional forces in dance are solely "virtual" and thus illusory. I plan to do so by means of the growing research in the branch of cognitive science known as Embodied Cognition.

In Brief: Susanne Langer, one of the most prominent philosophers of Aesthetics, contends that dance is able to express emotions as an external force, while creating what she calls a "primary illusion". Langer attributes gesture as the basic abstraction whereby the dance illusion is made and organized. Furthermore, she contends that dance is not …

A Revolution In Rhetoric: Recycling The Language Of Control Through Rhetorical Activism, Jerien Elizabeth Rausch

Open Access Theses & Dissertations

The English language, with its infinite space and possibility, is and can be recycled to recreate authority of voice and representations of the past. Where once language was used for creating and maintaining colonial control, now, with its careful study and critical (re)applications through fictions written as alternative versions of colonial events, it can be a source of power for the reclamations of identity, culture, religion, history, story, context, and imagination. This study (re)examines an iconic exploration and colonial narrative to highlight the rhetoric used to capture and create Indigenous Peoples and places. Additionally, this study explores how works of …
