Landing: On The Other Side, Marianita Escamilla

Theses and Dissertations - UTB/UTPA

Landing: On the Other Side a collection of essays that discuss one woman's struggle with the Chronic Fatigue Syndrome, Fibromyalgia (FM). The narratives are organized non-chronologically because the more pervasive effects of this chronic illness manifest in waves that do not follow a simple means of progression. Rather, FM's most powerful symptom is the highly variable pain strength coupled with its unpredictability.

The mass marketability of this text, as with other illness/disability narratives, lies in the universal message of prevailing against adversity. A person need not suffer from this illness or any ailment to comprehend the narrator's plight. While this …

Assessment And Treatment Of Elopement In Young Children With Autism, Ivette Andrade

Theses and Dissertations - UTB/UTPA

Elopement, leaving a caregivers side without permission or supervision, is a behavior that is more prevalent among children with autism as compared to their typically developing peers.

A Dynamic Stochastic Model For Converging Inbound Air Traffic, Jun Chen

Open Access Theses

Weather accounts for the majority of congestion in the National Airspace System which highlights the importance of addressing weather uncertainty to mitigate delays, and this paper presents an effort in this direction. Firstly, a new dynamic stochastic 0-1 Integer Programming (IP) model is proposed, which models the Single Airport Ground Holding Problem (SAGHP) with respect to uncertainty in the separation between flights instead of Airport Acceptance Rate (AAR) or landing capacity. Uncertainty in separation according to different weather conditions is represented through the scenario tree by using stochastic linear programming. Considering time separation constraints instead of AAR constraints, our model …

Competition Between Private Labels And National Brands: Empirical Evidence From Homescan Data On Fluid Milk Markets, Jeffrey S. Young

Open Access Theses

The purpose of this study is to empirically examine the nature of the pricing relationship between private labels (or "store brands") and national brands. To accomplish this, we control for the exogenous variation in the farm price of a commodity that serves as the main agricultural input common to both private labels and national brands (any shocks to this farm price will pass through to both retail prices - private label and retail). The product of choice is fluid milk, as the farm price of milk comprises a large share of producer and retailer cost.

Two examples of underlying theories …

Market Power Estimation In The Chilean Cattle Market, Rodirgo A. Vasquez Panizza

Open Access Theses

The cattle market in Chile is constituted by cattle slaughtering firms and farmers; the industry demands cattle but also demands beef imports. Based in antecedents of market concentration in this sector, I make a system of equations model based on the NEIO approach to determine market power for the period April 1993 - December 2008. The results show that there is no market power in the aggregated market as well as in the disaggregated market by sex and age type, which is explained because the special features of this market in Chile.

Capacity-Related Driver Behavior On Modern Roundabouts Built On High-Speed Roads, Shaikh Ahmad

Open Access Theses

The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of drivers as represented by critical headway (critical gap) and follow-up headway (follow-up time). The effects of heavy vehicles (single-unit truck, bus, and semi-trailer) and area type (rural or urban) on roundabout capacity were investigated by comparing the critical headways for roundabouts located on high-speed and low-speed roads. The effects of nighttime conditions (in the presence of street lighting) were also considered. Data were collected using the Purdue …

The Barriers To Adopting Composting Toilets Into Use In Urban And Suburban Locations In The United States, Julia Branstrator

Open Access Theses

The amount of fresh water available in the world is a finite resource. Large quantities of the fresh water are located in remote locations, while more accessible sources of fresh water are disproportionately distributed around the world. Some populations lack reliable access to clean water for daily life, making the routine use of potable water in toilets of upper-income countries a questionable practice in terms of resource responsibility, energy use, and sustainable infrastructure. The innovative nature of composting toilets offers potential solutions to the downfalls of conventional, waterborne toilets. However, the path to adoption of composting toilets has encountered barriers …

Faut-Il Obéir À La Loi ? – Les Pensées Politiques Des Femmes Dans La Littérature Épistolaire Et Les Mémoires Choisis À L’Époque De La Révolution Française, Justyna Czader

Open Access Theses

L'écriture est un témoin qui est difficilement corrompu-Montesquieu, L'esprit des lois. Mémoires and lettres de prisons take us to places we haven't been: prisons in bloody revolutionary Paris and the deadly Place de la Concorde. Women with different social backgrounds fought for their rights denied officially by the revolutionary authorities. They fought back was through plays, mémoires or letters. According to Philippe Lejeune, since the 18th century autobiography has become a phenomenon of civilization. I argue that the lettres de prison present not only a form of epistolary communication, but also as many personal testimonies, recollections of events and emotions …

Disrupting Infrastructure: Social Media And Accessing Digital Publics, Carolyn K. Grant

Open Access Theses

This thesis investigates infrastructural barriers to effecting change through social media participation. Though social media is said to hold "democratic potential" by enabling open access to the digital public sphere, in reality it is often still the most privileged voices that get heard. Even in success cases of the power of social media like the Arab Spring, situational contexts lead to particular infrastructural access points that are not universally transferable, and still tend to favor mainstream perspectives. Barriers to amplifying marginalized voices include inadequate systems for digital memory and sharing algorithms that promote the visibility of the already visible. These …

Uncertainty, Irreversibility, And Investment In Secondgeneration Biofuels, Tanner Joseph Mccarty

Open Access Theses

The present study formalizes and quantifies the importance of uncertainty for investment in a corn-stover based cellulosic biofuel plant. Using a real options model we recover prices of gasoline that would trigger entry into the market and calculate the portion of that entry trigger price required to cover cost and the portion that corresponds to risk premium. We then discuss the effect of managerial flexibility on the entry risk premium and the prices of gasoline that would trigger mothballing, reactivation, and exit. Results show that the risk premium required by plants to enter the second-generation biofuel market is likely to …
