The Biopsychosocial Approach to Understanding, Subtyping, and Treating Depression: Results from the National Comorbidity Survey - Replication.
The most effective and useful way to diagnose and subtype depression has been a long debated topic which even now does not have a definite answer. The biopsychosocial approach to diagnosis may be a solution to this problem by linking various etiologies to symptom presentation. The biopsychosocial model, in regard to depression, takes into account biological risk factors/contributors, psychological or cognitive risk factors/contributors, and social risk factors/contributors to depression when making diagnosis and subtyping determinations. However, the most effective way to use this model in the assessment, diagnosis, and treatment of depression is not yet clear. In this study, the utility of the biopsychosocial model as an effective approach to conceptualizing and treating depression was assessed by testing hypotheses that showed that etiological contributors are related to the presence and differential presentation of depression, and that these etiologically-based subtypes of depression respond differently to different forms of treatment. These hypotheses were tested using data from the National Comorbidity Survey - Replication (NCS-R). Results showed that the biopsychosocial model can effectively predict the presence, severity and chronicity of depression, and may inform specific biopsychosocially-based subtypes. No conclusions could be drawn regarding success in treatment based on the biopsychosocial model. Future directions for research based on the current study are discussed.
Bioresorbable Polymer Blend Scaffold for Tissue Engineering
Tissue engineering merges the disciplines of study like cell biology, materials science, engineering and surgery to enable growth of new living tissues on scaffolding constructed from implanted polymeric materials. One of the most important aspects of tissue engineering related to material science is design of the polymer scaffolds. The polymer scaffolds needs to have some specific mechanical strength over certain period of time. In this work bioresorbable aliphatic polymers (PCL and PLLA) were blended using extrusion and solution methods. These blends were then extruded and electrospun into fibers. The fibers were then subjected to FDA standard in vitro immersion degradation tests where its mechanical strength, water absorption, weight loss were observed during the eight weeks. The results indicate that the mechanical strength and rate of degradation can be tailored by changing the ratio of PCL and PLLA in the blend. Processing influences these parameters, with the loss of mechanical strength and rate of degradation being higher in electrospun fibers compared to those extruded. A second effort in this thesis addressed the potential separation of the scaffold from the tissue (loss of apposition) due to the differences in their low strain responses. This hypothesis that using knit with low tension will have better compliance was tested and confirmed.
Bipolar Disorder in the Family: Impact on Functioning and Adjustment to College
Bipolar disorder is a serious mental disorder, affecting anywhere from 2 to 4 percent of Americans. Though research has indicated that this disorder can be devastating for patients, less is known about how the disorder impacts family members. There is no research that has considered impacts on family members adjusting to college. The purpose of the current study was to determine the extent to which having a family member with bipolar disorder impacts adjustment to college, as well as factors that might account for worse functioning. Two groups were recruited: students with a bipolar family member (n = 25) and students with no family history of the disorder (n = 50). Participants were interviewed regarding their own histories of a mood disorder, as well as mood disorder histories in their immediate families. They then completed surveys assessing adjustment to college, functioning, caregiving burden, parental relationship, and attachment style. Students with a family history of bipolar disorder had significantly lower social adjustment scores, lower personal-emotional adjustment scores, and lower financial functioning scores than students without this history. Lower scores were found even after controlling for psychopathology. Avoidant attachment behaviors, anxious attachment behaviors, and aspects of the paternal relationship were identified as potential mediators. Caregiving burden was identified as a partial mediator. Implications for families and educational institutions are discussed.
"Black Reparations Film Project: Descendants of Slavery and Institutional Racism"
Black Reparations Film Project: Descendants of Slavery and Institutional Racism is a character driven film that sheds light on the consequences of slavery in the U.S. Through a personal narrative, the viewer comes to understand how these consequences support the argument for slavery reparations. The purpose of the film is to bridge the generational gap in awareness of reparation history. The film can be used to enlighten young Americans of all ethnicities to encourage them to find their purpose in this country, help build better race relations, and work towards building a true democracy.
BLE Controller Module for Wireless Sensor Networks
Sensors have been an integral part of our life since a long time. Traditionally, the transmit information to a data collection center through a physical wire. However, with the introduction of Bluetooth Low Energy (BLE) communication protocol, more research is being done into the field of wireless sensor networks (WSN). BLE was introduced to target low power applications. The CC2650 Launchpad designed by Texas Instruments (TI) can lead to a bulky final product. The aim was to design hardware for the CC2650 micro-controller with the aim of making it more compact for use in WSNs. A top-down approach was used wherein the available product is studied to identify the redundant and reverse engineer it to design a new product. A 2 layer printed circuit board (PCB) was designed which resulted in a 64 percent decrease in size compared to the Launchpad. Also, experiments were performed to test the proof of concept.
Blood and Earth: Indivisible Territory and Terrorist Group Longevity
The study of terrorism has been both broad in scope and varied in approach. Little work has been done, however, on the territorial aspects of terrorist groups. Most terrorist groups are revolutionary to one degree or another, seeking the control of a piece of territory; but for the supportive population of a terrorist group, how important is the issue of territory? Are the intangible qualities of territory more salient to a given population than other factors? Are territorially based terrorist groups more durable than their ideologically or religiously motivated cohorts? This paper aims to propose the validity of the territorial argument for the study of political terrorism.
Blood Brothers
Blood Brothers as a media project works as a diptych. There are two – seemingly identical – pieces of the project that must both be experienced to understand the project as a whole. The first piece of the project is the linear documentary. This part captures the experience as it exists in the past. It exists as a master copy of the original story of mine and my foster brother’s relationship. This version of the story will always exist in the past. The second part is the live-cinema documentary performance. In this version of the story, my foster brother and I are no longer only images on a screen; we are living, breathing, and emotional subjects in the present. Our presence alters how the audience consumes the material.
Blueline Concerto: Critical Essay
The purpose of this critical essay is two-fold. First, the essay presents a detailed critical analysis of my original composition, Blueline Concerto for bass trombone and wind ensemble. Second, using Blueline Concerto, the essay presents preliminary findings of my study to develop an approach to composing that takes into account the musicians' health, specifically regarding noise induced hearing loss (NIHL). Through various hypothesized composition- and orchestral-based approaches, I test effectiveness on changes in NIHL risk while also noting that artistic merit and compositional integrity is preserved.
Bodies and Other Firewood
The chakra system consists of seven energetic vortexes ascending up the spine that connect to every aspect of human existence. These vortexes become blocked and unblocked through the course of a life, these openings and closings have physiological and mental repercussions. Knowledge of these physical and mental manifestations, indicate where the chakra practitioner is in need, the practitioner can then manipulate their mind and body to create a desired outcome. These manipulations are based upon physical exercises and associative meditations for the purpose of expanding the human experience. As a poem can be thought of as the articulation of the human experience, and the chakra system can be thought of as a means to understand and enhance that experience, it is interesting and worthwhile leap to explore the how the chakras can develop and refresh the way we read and write poetry. This critical preface closely reads seven poems, one through each chakra, finding what the chakras unveil. Here, each chakra is considered for its dynamic creative capabilities and for its beneficial potentiality in the reading and writing process, finding each chakra provides tools: idea generators with the potential to free the poet from usual patterns of creativity while broadening vision and expressivity. In this collection of poetry poems are experiences chopped into consumable units that show and tell the constant negotiation between what is actually happening and the stories we tell ourselves about what is happening.
Bodies of Evidence: A Qualitative Analysis of the Lived Experiences of Female Central American and Mexican Asylum Seekers in Dallas
This work addresses the experiences of female asylum seekers from Central and Mexico currently living in Dallas, TX. The main purpose is to analyze how these women engage in the gendered processes of both migrating to and accessing legal resources and protection within the United States. As the women move through male-dominated spaces in their home country, the borderlands, and the asylum court they must challenge the patriarchal institutions that attempt to silence their narratives and criminalize their bodies. Their physical wounds become evidence in the courtroom, while outside of the courtroom their movements are monitored and tracked through multiple mechanisms of state control: ankle monitors, detention centers, ICE check-ins. They face intersectional discrimination as they are targeted as both women and immigrants. However, these female asylum seekers are not victims. They constantly display agency as they represent themselves in court, find solace in their faith, and form community with each other.
Body Dissatisfaction, Disordered Eating Behaviors and Body Image Quality of Life in African American Women with Hiv
The purpose of the current study was to further our understanding of the subjective experience of middle-age African American women who are HIV+ and on highly active antiretroviral therapy, particularly how self-reported lipodystrophy (LD), levels of body dissatisfaction, body image quality of life, and engagement in disordered eating behaviors are related. Multiple regression, MANOVA, MANCOVA, ANOVA, and chi-square were utilized to test hypotheses. Results revealed that HIV+ and HIV- women did not differ significantly on their levels of body dissatisfaction or drive for thinness. When HIV+ women were examined in more detail a pattern emerged: women who self-reported fat hypertrophy had significantly higher levels of body dissatisfaction, bingeing, but not purging, and dietary restriction and fear of weight gain compared to women who did not self-report LD. About 75% of the sample was overweight or obese, and when BMI was controlled for, these differences persisted for body dissatisfaction and disordered eating behaviors for fat hypertrophy, but not fat atrophy. Overall, the findings indicate that the type of LD, specifically hypertrophy, is more related to body dissatisfaction and disordered eating behaviors, than LD in general. Clinical implications and limitations of these findings are discussed.
Booty Calls, Rage, and Racialized/sexualized Subjects: Tmz's Coverage of Rihanna and Chris Brown
Internet-based celebrity gossip blog site, TMZ, is a growing cultural force. Employing critical rhetorical analytics, the author examines the TMZ coverage of Chris Brown's assault on his then-girlfriend, Rihanna. This project explicates TMZ's enthymematic invocation of dominant cultural ideologies surrounding race, sex, and domestic violence. Chapter 1 demonstrates the theoretical importance of both celebrities and gossip blogs, signaling the ideological importance of each. Chapter 2 critiques TMZ's reliance on historic myths regarding sex and race in their reporting on this case. Chapter 3 analyzes TMZ's humorous and affective strategies that bolster broader investments in colorblind ideologies. Chapter 4 concludes by examining the interplay of formal rhetorical elements that inform the project's findings. This research reveals that TMZ utilizes affective, enthymematic strategies that camouflage broader racist and sexist ideological impulses that perpetuate domestic violence myths.
Boron Nitride by Atomic Layer Deposition: A Template for Graphene Growth
The growth of single and multilayer BN films on several substrates was investigated. A typical atomic layer deposition (ALD) process was demonstrated on Si(111) substrate with a growth rate of 1.1 Å/cycle which showed good agreement with the literature value and a near stoichiometric B/N ratio. Boron nitride films were also deposited by ALD on Cu poly crystal and Cu(111) single crystal substrates for the first time, and a growth rate of ~1ML/ALD cycle was obtained with a B/N ratio of ~2. The realization of a h-BN/Cu heterojunction was the first step towards a graphene/h-BN/Cu structure which has potential application in gateable interconnects.
Bouncing Back: Resilience as a Moderator between Aggression and Depression in Older Gay Men and Lesbians Group Differences
Older gay men and lesbians may be at greater risk for depression than older sexual majority adults due to a lifetime of sexual minority stress. We hypothesize that aggression and being single are positively associated with depression. Resilience is negatively associated with depression. Aggression, being single and resilience account for a significant proportion of variance in depression. Resilience moderates the relationship between aggression and depression. Significant differences between older gay men and older lesbians' aggression, resilience and depression scores exist. For our older gay men and lesbian combined group, a moderation analysis indicated that in addition to aggression and resilience, being single significantly predicted depression accounting for approximately 57% of the variance in depression. Furthermore, resilience significantly moderated the relationship between aggression and depression in our model of older gay men and lesbians. For our older gay men-only group a moderation analysis (indicated that and resilience significantly predicted depression accounting for approximately 57% of the variance in depression. Furthermore, resilience significantly moderated the relationship between aggression and depression in our model, in our sample of older gay men. Four our lesbian-only group a moderation analysis indicated that being single and resilience significantly predicted depression accounting for approximately 54% of the variance in depression.
Brain Computer Interface (BCI) Applications: Privacy Threats and Countermeasures
In recent years, brain computer interfaces (BCIs) have gained popularity in non-medical domains such as the gaming, entertainment, personal health, and marketing industries. A growing number of companies offer various inexpensive consumer grade BCIs and some of these companies have recently introduced the concept of BCI "App stores" in order to facilitate the expansion of BCI applications and provide software development kits (SDKs) for other developers to create new applications for their devices. The BCI applications access to users' unique brainwave signals, which consequently allows them to make inferences about users' thoughts and mental processes. Since there are no specific standards that govern the development of BCI applications, its users are at the risk of privacy breaches. In this work, we perform first comprehensive analysis of BCI App stores including software development kits (SDKs), application programming interfaces (APIs), and BCI applications w.r.t privacy issues. The goal is to understand the way brainwave signals are handled by BCI applications and what threats to the privacy of users exist. Our findings show that most applications have unrestricted access to users' brainwave signals and can easily extract private information about their users without them even noticing. We discuss potential privacy threats posed by current practices used in BCI App stores and then describe some countermeasures that could be used to mitigate the privacy threats. Also, develop a prototype which gives the BCI app users a choice to restrict their brain signal dynamically.
Branded Content: Understanding the Mechanisms of Strategic Messaging in Entertainment Television Formats
Branded content as an advertising tactic is a growing phenomenon that is not widely researched and is generally ambiguous in nature. This study uses qualitative methods to explain how branded content is defined, how it functions, and how it can influence a brand. Case studies of IKEA and Chevrolet were compared alongside four interviews with branded content professionals. the data collected suggests that branded content in structure and substance is varied, however it comprises engagement, the brand, and financial transaction. the data collected also suggested that brands take a variety of stances when controlling content to support their brand, and that branded content generally supports the intangible aspects of a brand, as opposed to product features.
Brass Band History and Idiomatic Writing in Brass Music
The purpose of this research was to explore historical perspective of brass music. There is a brief history of brass bands in Britain. Furthermore, the paper examines the differences between two brass band pieces in the repertoire, A Western Fanfare by Eric Ewazen and Brass Symphony by Jan Koetsier. Both of these pieces were compared and contrasted against the author's newly composed work for brass, Two Companion Pieces for Brass Ensemble. The paper covers different techniques commonly used in brass writing and points these techniques out in all three pieces.
The Brazos Valley Groundwater Conservation District: A Case Study in Texas Groundwater Conservation
This thesis examines the history of groundwater management through the development of groundwater conservation districts in Texas. Political, economic, ideological, and scientific understandings of groundwater and its regulation varied across the state, as did the natural resource types and quantities, which created a diverse and complicated position for lawmakers and landowners. Groundwater was consistently interpreted as a private property right and case law protected unrestricted use for the majority of the twentieth-century even as groundwater resources crossed property and political boundaries, and water tables declined particularly during the second-half of the century. The case study of the Brazos Valley Groundwater Conservation District describes the complicated history of groundwater in Texas as the state attempted to balance natural resource legislation and private property rights and illuminate groundwater’s importance for the future.
Bread, Bullets, and Brotherhood: Masculine Ideologies in the Mid-Century Black Freedom Struggle, 1950-1975
This thesis examines the ways that African Americans in the mid-twentieth century thought about and practiced masculinity. Important contemporary events such as the struggle for civil rights and the Vietnam War influenced the ways that black Americans sought not only to construct masculine identities, but to use these identities to achieve a higher social purpose. The thesis argues that while mainstream American society had specific prescriptions for how men should behave, black Americans were able to select which of these prescriptions they valued and wanted to pursue while simultaneously rejecting those that they found untenable. Masculinity in the mid-century was not based on one thing, but rather was an amalgamation of different ideals that black men (and women) sought to utilize to achieve communal goals of equality, opportunity, and family.
Breaking Accidental Behavior Chains.
Accidental behavior chains are a common problem in dog training. Many handlers inadvertently reinforce undesirable behaviors. The behavior analytic literature already contains articles describing methods of breaking chains; however, those methods either are not used in dog training for practical purposes or are ineffective in dog training. This experiment investigated two ways to break a behavior chain, including extending the chain and introducing a delay into the chain. The results of extending the chain showed that it is possible to decrease the target behavior using this method, but it was not eliminated in this study. Adding a delay into the behavior chain resulted in a quick elimination of the target behavior.

brk1 and dcd1 Act Synergistically in Subsidiary Cell Formation in Zea mays
Subsidiary mother cell (SMC) divisions during stomatal complex formation in Zea mays are asymmetric generating a small subsidiary cell (SC) and a larger epidermal cell. Mutants with a high number of abnormally shaped subsidiary cells include the brick1 (brk1) and discordia1 (dcd1) mutants. BRK1 is homologous to HSPC300, an ARP2/3 complex activator, and is involved in actin nucleation while DCD1 is a regulatory subunit of the PP2A phosphatase needed for microtubule generation (Frank and Smith, 2002; Wright et al. 2009). Possible causes of the abnormal SCs in brk1 mutants include a failure of the SMC nucleus to polarize in advance of mitosis, no actin patch, and transverse and/or no PPBs (Gallagher and Smith, 2000; Panteris et al 2006). The abnormal subsidiary mother cell division in dcd1 is due to correctly localized, but disorganized preprophase bands (PPBs; Wright et al. 2009). The observation that brk1 has defects in PPB formation and that the dcd1 phenotype is enhanced by the application of actin inhibitors led us to examine the dcd1; brk1 double mutant (Gallagher and Smith, 1999). We found that dcd1; brk1 double mutants demonstrate a higher percentage of aberrant SCs than the single mutants combined suggesting that these two mutations have a synergistic and additive effect on SC formation. Our observations and results are intriguing and the future step will be to quantitate the abnormal PPBs and phragmoplasts in the double and single mutants using immunolocalization of tubulin and actin as well as observations of live cells expressing tubulin-YFP.
BSM Message and Video Streaming Quality Comparative Analysis Using Wave Short Message Protocol (WSMP)
Vehicular ad-hoc networks (VANETs) are used for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. The IEEE 802.11p/WAVE (Wireless Access in Vehicular Environment) and with WAVE Short Messaging Protocol (WSMP) has been proposed as the standard protocol for designing applications for VANETs. This communication protocol must be thoroughly tested before reliable and efficient applications can be built using its protocols. In this paper, we perform on-road experiments in a variety of scenarios to evaluate the performance of the standard. We use commercial VANET devices with 802.11p/WAVE compliant chipsets for both BSM (basic safety messages) as well as video streaming applications using WSMP as a communication protocol. We show that while the standard performs well for BSM application in lightly loaded conditions, the performance becomes inferior when traffic and other performance metric increases. Furthermore, we also show that the standard is not suitable for video streaming due to the bursty nature of traffic and the bandwidth throttling, which is a major shortcoming for V2X applications.
Building Relationships between a Free Clinic and Its Donors
This thesis presents qualitative research conducted in summer 2017 at the Finger Lakes Free Clinic, which provides free medical and holistic care to people without insurance in upstate New York. The primary goal of this research was to strengthen the relationship between a free clinic and its donors by gathering donor concerns and perceptions regarding federal healthcare policy. Data from 32 interviews with donors, staff, board members, and volunteers, along with 100 hours of participant observation revealed that donors to this clinic were concerned about the potential impact of Congressional healthcare reform yet did not consider federal policy a strong influence on their donations. Rather, donors cited dedication to local giving and personal connections with the clinic as their primary motivations. These motivations suggest the value of viewing the clinic-donor relationship as a relationship of reciprocity. From this framework, the research identifies opportunities for the clinic to reciprocate donor generosity while expanding services in response to a growing need. Insights from the research will guide the clinic's response to federal policy changes and support the clinic's vision of becoming a national model for integrative care.
The Burner Project: Privacy and Social Control in a Networked World
As mobile phones become increasingly ubiquitous in today’s world, academic and public audiences alike are curious about the interaction between mobile technologies and social norms. To investigate this phenomenon, I examined how individuals use technology to actively manage their communication behaviors. Through a three-month research project on usage patterns of Burner, a mobile application, this thesis explores the relationships among technology, culture, and privacy. Burner is a service that equips individuals with the means to create, maintain, and/or dissolve social ties by providing temporary, disposable numbers to customers. The application offers a way to communicate without relying on a user’s personal phone number. In other words, Burner acts as a “privacy layer” for mobile phones. It also provides a valuable platform to examine how customers use the application as a strategy for communication management. This thesis represents a marriage of practice and theory: (1) As an applied enterprise, the project was constructed as a customer needs assessment intending to examine how the service was situated in the lives of its users. The findings have successfully been applied to my client’s company strategy and have led to a more informed customer approach. (2) As an academic endeavor, this research contributes to existing scholarship in anthropology, computer-mediated communication, privacy, and design. The results provide rich fodder for discussions about the impact of mobile communication and services.
Burushaski Case Marking, Agreement and Implications: an Analysis of the Hunza Dialect
This thesis was written to explore the structural case patterns of the Burushaski sentence and to examine the different participant coding systems which appear between noun marking and verb agreement. Verb suffixes follow nominative alignment patterns of agreement, while the verb prefix agrees with the affected argument as determined by semantic relations, as opposed to syntactic ones. The agent noun phrase is directly marked when highly active or volitional, suggesting a system of agent marking on the noun phrase and nominative alignment on the verb suffix. Nominative alignment also allows for a less marked presence of passive voice. Burushaski's agent marking is not entirely consistent; however, its nominative alignment is consistent. The conclusion is that Burushaski is not an ergative language at all.
La Búsqueda de la Identidad Femenina en las Novelas de Dos Autoras Mexicanas
The novel is one means by which writers can provide examples of the possibilities for women in patriarchal societies to seek greater independence. Sabina Berman (1955- ) and Silvia Molina (1946- ) are modern day Mexican novelists whose writings support the betterment of the female condition in this Latin American society. This study focuses on these two authors and describes and analyzes several of their female protagonists who can be characterized as being in search of their self-identity and self-realization. The novels of interest are La Bobe (2006) and La Mujer que Buceó Dentro del Corazón del Mundo (2010) by Sabina Berman and La Mañana Debe Seguir Gris (1977) and El Amor Que Me Juraste (1998) by Silvia Molina. The theoretical framework used to analyze these novels is based on The Second Sex by Simone de Beauvoir and on the writings of the Mexican author Rosario Castellanos. These novels provide examples of how women can challenge patriarchal social norms in order to seek their identity as an individual and their self-realization. However, to do this, women must be willing to accept the risks and costs that may accompany this self-searching. By seeking identity women can satisfy their longings and desires, but at the same time this may also produce undesired results. Nevertheless, these novels show that women have the ability to seek their personal identity if they take the initiative to do so.
Caffeine’s Effects on Pausing During Alternating Work Requirements
There is a significant body of literature stating that caffeine is the most widely consumed drug in the world, yet its effects on operant behavior are little understood. Some of the current research on caffeine suggests that it may play a role in altering motivational states related to transitions between previous and upcoming work requirements. The purpose of the current study was to examine the effects of caffeine on postreinforcement pausing during transitions between small and large fixed ratio rudiments. Eight rats were exposed to five doses of caffeine and and a two-component multiple schedule. We found that caffeine does systematically alter the length of pausing during transitions between fixed ratio requirements, however the magnitude of the effect may be dependent on the baseline rate of responding.
“Campaigns Replete with Instruction”: Garnet Wolseley’s Civil War Observations and Their Effect on British Senior Staff College Training Prior to the Great War
This thesis addresses the importance of the American Civil War to nineteenth-century European military education, and its influence on British staff officer training prior to World War I. It focuses on Garnet Wolseley, a Civil War observer who eventually became Commander in Chief of the Forces of the British Army. In that position, he continued to write about the war he had observed a quarter-century earlier, and was instrumental in according the Civil War a key role in officer training. Indeed, he placed Stonewall Jackson historian G.F.R. Henderson in a key military professorship. The thesis examines Wolseley’s career and writings, as well as the extent to which the Civil War was studied at the Senior Staff College, in Camberly, after Wolseley’s influence had waned. Analysis of the curriculum from the College archives demonstrates that study of the Civil War diminished rapidly in the ten years prior to World War I.
Campania In-Felix (Unhappy Country)
This documentary film explores the damages produced by the illegal dumping of toxic waste in the environment and the rise in health concerns specific to the Campania region in Southern Italy. The management of waste material in the region is in the hands of the Camorra - a mafia organization with vast economic and political power. Through the narration of personal stories, the documentary reveals the broken emotional and cultural balance between the people from the region and their land.
Can Observing Behavior Predict Performance in Conditional Discriminations?
Prompts are implemented often in training procedures, to include conditional discriminations, and this can lead to prompt dependency. The current study extends a prior study that suggested that the effectiveness of supplementary visual stimuli displaying the sample and comparison was dependent on the timing in relation to the selection task, presented as a prompt or feedback, in a match-to-sample procedure. The current research examines if the differences in that effectiveness were due to differences in observing behavior in those two conditions. Measures of observing behavior were determined by making access to the individual visual stimuli contingent on clicking on the visual stimulus and keeping the cursor located on the stimulus. Participants viewed the sample comparison much less than the comparison stimulus in both the prompt and feedback conditions. Latency to select the comparison stimulus was much shorter for the prompt condition suggesting that the participants might have interacted differently with the selection task in the two conditions.
Can Positive Reinforcement Overcome Fear? An Investigation of Competing Contingencies
Escape maintained behavior in dogs is generally displayed by one of two behaviors-fleeing or aggression. Once aggression is negatively reinforced by the removal of the aversive stimulus, it is very difficult to eliminate from the organism's repertoire. Counterconditioning is the process of pairing a positive reinforcer with an aversive stimulus in the attempts that an organism will no longer exhibit fear responses in its presence. This process must be done gradually with small approximations. Many organisms have been trained to tolerate the presence of aversive stimuli via counterconditioning. However, this process can be time consuming and has inconsistent results. The purpose of this experiment was to monitor the effects of counter conditioning around an aversive stimulus while simultaneously training an identical behavior in the presence of a neutral stimulus. The results demonstrated that even though counterconditioning produced approach to the aversive stimulus the subject still exhibited numerous fear responses when results were compared to the control condition.
Capital Ships, Commerce, and Coalition: British Strategy in the Mediterranean Theater, 1793
In 1793, Great Britain embarked on a war against Revolutionary France to reestablish a balance of power in Europe. Traditional assessments among historians consider British war planning at the ministerial level during the First Coalition to be incompetent and haphazard. This work reassesses decision making of the leading strategists in the British Cabinet in the development of a theater in the Mediterranean by examining political, diplomatic, and military influences. William Pitt the Younger and his controlling ministers pursued a conservative strategy in the Mediterranean, reliant on Allies in the region to contain French armies and ideas inside the Alps and the Pyrenees. Dependent on British naval power, the Cabinet sought to weaken the French war effort by targeting trade in the region. Throughout the first half of 1793, the British government remained fixed on this conservative, traditional approach to France. However, with the fall of Toulon in August of 1793, decisions made by Admiral Samuel Hood in command of forces in the Mediterranean radicalized British policy towards the Revolution while undermining the construct of the Coalition. The inconsistencies in strategic thought political decisions created stagnation, wasting the opportunities gained by the Counter-revolutionary movements in southern France. As a result, reinvigorated French forces defeated Allied forces in detail in the fall of 1793.
The Captain of the People in Renaissance Florence
The Renaissance Florentine Captain of the People began as a court, which defended the common people or popolo from the magnates and tried crimes such as assault, murder and fraud. This study reveals how factionalism, economic stress and the rise of citizen magistrate courts eroded the jurisdiction and ended the Court of the Captain. The creation of the Captain in 1250 occurred during the external fight for dominance between the Holy Roman Emperor and the Pope and the struggle between the Guelfs and Ghibellines within the city of Florence. The rise of the Ciompi in 1379, worried the Florentine aristocracy who believed the Ciompi was a threat to their power and they created the Otto di Guardia, a citizen magistrate court. This court began as a way to manage gaps in jurisdiction not covered by the Captain and his fellow rectors. However, by 1433 the Otto eroded the power of the Captain and his fellow rectors. Historians have argued that the Roman law jurists in this period became the tool for the aristocracy but in fact, the citizen magistrate courts acted as a source of power for the aristocracy. In the 1430s, the Albizzi and Medici fought for power. The Albizzi utilized a government mandate, which had the case already carried out or a bullectini to exile Medici adherents. However, by 1433, the Medici triumphed and Cosimo de Medici returned to the city of Florence. He expanded the power of the Otto in order to utilize the bullectini to exile his enemies. The expansion of jurisdiction of the Otto further eroded the power of the Captain. Factionalism, economic stress and the rise of the citizen magistrate courts eroded the power of the Captain of the people.
Cardiovascular Response to a Behavioral Restraint Challenge: Urge Magnitude Influence in Men and Women
Agtarap, Wright, Mlynski, Hammad, and Blackledge took an initial step in providing support for the predictive validity of a new conceptual analysis concerned with behavioral restraint, defined as active resistance against a behavioral impulse or urge. The current study was designed to partially replicate and extend findings from their study, employing a common film protocol and a procedure for inducing low- and high levels of fatigue. Analyses on key data indicated that the fatigue manipulation was ineffective. On the other hand, they supported the suggestion that behavioral restraint should be proportional to the strength of an urge being resisted so long as success is perceived as possible and worthwhile. Analyses also provided evidence of gender differences for this behavioral restraint task. Women showed relatively enhanced CV responses to my manipulation of urge magnitude, performed less well, rated the behavioral restraint challenge as harder, and rated success on the more difficult behavioral restraint task as more important. A broad indication is that men and women can differ in the strength of impulses they experience in response to stimulus presentations as well as in the importance they place on resisting the impulses.
Caring for Cancer: Understanding the Access and Perceptions of Psychosocial Cancer Services in North Texas
It is estimated that nearly 14.5 million Americans are living with cancer today. A commonly overlooked component to quality cancer care, as defined by the Institute of Medicine, is the role of psychological and social support. Better known as psychosocial support, these needs reflect a broad spectrum of obstacles or assets in an individual’s personal life that may help or hinder their healing experience. Some psychosocial examples include coping skills, transportation to medical appointments, or appropriate knowledge to mitigate the physical impacts of the cancer process. Research has shown that by addressing these potential needs, a better health outcome may be achieved for cancer patients. Through participant observation at local psychosocial service establishments and through semi-structured interviews with service providers and adults diagnosed with cancer living in the Dallas-Fort Worth region, this thesis research seeks to explore how local cancer patients are learning of psychosocial services available to them, what barriers may exist in accessing these services, and what individuals may be doing to address their psychosocial needs, both formally or informally. Results yielded recommendations for local psychosocial providers to adjust their marketing of services and kinds of services offered as well as yielded recommendations for future academic research.
Carnaval, grotesco y dialogismo en las zarzuelas de Pablo Sorozábal
In the present study, the three principal theories of Russian theorist Mikhail Bakhtin--the carnavalesque, grotesque, and dialogical--are applied to the musical-theatre genre of the Spanish zarzuela. The focus of the study centers on the works of composer Pablo Sorozábal and the various librettists who collaborated with him, among them the renowned literary author Pío Baroja. Within this study, zarzuela is first analyzed on its own in terms of the academic debate surrounding the genre and its importance in terms of both literary and musical criticism. After establishing the particular capacity of the zarzuela to make important cultural contributions, the central theoretical framework of the thesis is established via Bakhtinian theory, and several links are drawn between this theory and the genre of the zarzuela, which is shown to be a body of work often capable of conveying subversive messages, both cultural and sociopolitical. With this critical lens, then, the specific sociopolitical context of Spain between 1931-1942 is analyzed and described in order to illustrate the various extratextual and intertextual elements at play in Sorozábal's zarzuelas. The three works ultimately studied are Katiuska (1931), Adiós a la bohemia (1933), and Black, el payaso (1942). By way of highlighting the Bakhtinian characteristics at play in these three zarzuelas, the composer's intention to challenge and criticize Spain's sociopolitical reality, including Francoist dictatorship, is revealed, illustrating the capacity of the zarzuela to challenge and transgress existing norms--an aspect that many critics have failed to recognize in the genre up to the present day.
Case Studies to Learn Human Mapping Strategies in a Variety of Coarse-Grained Reconfigurable Architectures
Computer hardware and algorithm design have seen significant progress over the years. It is also seen that there are several domains in which humans are more efficient than computers. For example in image recognition, image tagging, natural language understanding and processing, humans often find complicated algorithms quite easy to grasp. This thesis presents the different case studies to learn human mapping strategy to solve the mapping problem in the area of coarse-grained reconfigurable architectures (CGRAs). To achieve optimum level performance and consume less energy in CGRAs, place and route problem has always been a major concern. Making use of human characteristics can be helpful in problems as such, through pattern recognition and experience. Therefore to conduct the case studies a computer mapping game called UNTANGLED was analyzed as a medium to convey insights of human mapping strategies in a variety of architectures. The purpose of this research was to learn from humans so that we can come up with better algorithms to outperform the existing algorithms. We observed how human strategies vary as we present them with different architectures, different architectures with constraints, different visualization as well as how the quality of solution changes with experience. In this work all the case studies obtained from exploiting human strategies provide useful feedback that can improve upon existing algorithms. These insights can be adapted to find the best architectural solution for a particular domain and for future research directions for mapping onto mesh-and- stripe based CGRAs.
A Case Study of Tu and Vous Use in the French Dubbing and Subtitling in an American Film
Translation and subtitling has always been a complicated dimension of the motion picture industry for years. The problem of dealing with linguistic elements in films and conveying them to audiences of different languages across the globe encompasses many difficulties regarding forms and structures of other languages. One of the more highly researched topics in French linguistic studies has been the use of address pronouns and a range of aspects related to their use and interpretation. Many studies have been conducted over the last sixty years in order to determine and understand these variables. An analysis of several of these studies reveals the many complexities involved in second-person pronoun choice in the French language and the development of the idea of pronoun choice as an act of social identity. The focus of this study is to provide an analysis of the use of formal and informal address pronoun use in the French subtitling and dubbing of an American film, Maid in Manhattan, in order to add, on a broader level, a way to differentially examine perceived norms in a variety of contexts within this medium.
The Castle/Nikki Heat Phenomenon: A Detailed Examination of Female Representation in Entertainment Media
As entertainment reflects a culture's ideology, it is important for researchers to study its messages and subsequently its potential meanings. Entertainment has the power to inform and persuade, creating models for behavior with which the public interacts. The entertainment texts for the purpose of this study are the Castle television series and the Nikki Heat novels. Together, they create a unique multi-layer fictional world. By using postmodern, feminist, communication, and entertainment theories, the results of this study provide a tightly focused lens which views a narrow aspect of entertainment media. Each text was thoroughly examined using textual analysis, Feminist Poststructuralist Discourse Analysis, and conversation analysis. Contrary to expectations, the results indicated that the Castle and Nikki Heat texts support hegemonic ideology, particularly through the use of exaggerated stereotypes, strict gender roles, imagery, and narrative choices that help perpetuate rape culture. The discussion outlines how these results can be interpreted through the dominant messages presented in the texts. This research is intended to serve as a foundation for future research regarding entertainment media.
Catalytic Properties and Mechanical Behavior of Metallic Glass Powders
Lack of crystalline order and microstructural features such as grain/grain-boundary in metallic glasses results in a suite of remarkable attributes including very high strength, close to theoretical elasticity, high corrosion and wear resistance, and soft magnetic properties. By altering the morphology and tuning of composition, MGs may be transformed into high-performance catalytic materials. In this study, the catalytic properties of metallic glass powders were demonstrated in dissociating toxic organic chemicals such as AZO dye. BMG powders showed superior performance compared to state of the art crystalline iron because of their high catalytic activity, durability, and reusability. To enhance the catalytic properties, high energy mechanical milling was performed to increase the surface area and defect density. Iron-based bulk metallic glass (BMG) of composition Fe48Cr15Mo14Y2C15B6 was used because of its low cost and ability to make large surface area by high energy ball milling. AZO dye was degraded in less than 20 minutes for the 9 hours milled Fe-BMG. However, subsequent increase in ball milling time resulted in devitrification and loss of catalytic activity as measured using UV-Visible spectroscopy. Aluminum-based bulk metallic glass (Al-BMG) powder of composition Al82Fe3Ni8Y7 was synthesized by arc-melting the constituent elements followed by gas-atomization. The particle size and morphology were similar to Fe-BMG with a fully amorphous structure. A small percentage of transition metal constituents (Fe and Ni) in a mostly aluminum alloy showed high catalytic activity, with no toxic by-products and no change in surface characteristics. Al-alloy particles, being light-weight, were easily dispersed in aqueous medium and accelerated the redox reactions. The mechanism of dye dissociation was studied using Raman and Infrared (IR) spectroscopy. Breaking of -C-H- and - C-N- bonds of AZO dye was found to be the primary mechanism. Mechanical behavior of individual BMG particles was evaluated by in situ pico-indentation in a scanning electron …
Cattle Capitol: Misrepresented Environments, Nineteenth Century Symbols of Power, and the Construction of the Texas State House, 1879-1888
State officials, between 1882 and 1888, exchanged three million acres of Texas Panhandle property for construction of the monumental Capitol that continues to house Texas government today. The project and the land went to a Chicago syndicate led by men influential in business and politics. The red granite Austin State House is a recognizable symbol of Texas around the world. So too, the massive tract given in exchange for the building, what became the "fabulous" XIT Ranch, also has come to symbolize the height of the nineteenth century cattle industry. That eastern and foreign capital dominated the cattle business during this period is lesser known, absorbed by the mythology built around the Texas cattle-trail period - all but at an end in 1885. This study examines the interaction of Illinois Republicans and Texas Democrats in their actions and efforts to create what have become two of Texas's most treasured symbols.
Causes of the Jewish Diaspora Revolt in Alexandria: Regional Uprisings from the Margins of Greco-Roman Society, 115-117 CE
This thesis examines the progression from relatively peaceful relations between Alexandrians and Jews under the Ptolemies to the Diaspora Revolt under the Romans. A close analysis of the literature evidences that the transition from Ptolemaic to Roman Alexandria had critical effects on Jewish status in the Diaspora. One of the most far reaching consequences of the shift from the Ptolemies to Romans was forcing the Alexandrians to participate in the struggle for imperial patronage. Alexandrian involvement introduced a new element to the ongoing conflict among Egypt’s Jews and native Egyptians. The Alexandrian citizens consciously cut back privileges the Jews previously enjoyed under the Ptolemies and sought to block the Jews from advancing within the Roman system. Soon the Jews were confronted with rhetoric slandering their civility and culture. Faced with a choice, many Jews forsook Judaism and their traditions for more upwardly mobile life. After the outbreak of the First Jewish War Jewish life took a turn for the worse. Many Jews found themselves in a system that classified them according to their heritage and ancestry, limiting advancement even for apostates. With the resulting Jewish tax (fiscus Judaicus) Jews were becoming more economically and socially marginalized. The Alexandrian Jews were a literate society in their own right, and sought to reverse their diminishing prestige with a rhetoric of their own. This thesis analyzes Jewish writings and pagan writings about the Jews, which evidences their changing socio-political position in Greco-Roman society. Increasingly the Jews wrote with an urgent rhetoric in attempts to persuade their fellow Jews to remain loyal to Judaism and to seek their rights within the construct of the Roman system. Meanwhile, tensions between their community and the Alexandrian community grew. In less than 100 years, from 30 CE to 117 CE, the Alexandrians attacked the Jewish community on …
A Century of Overproduction in American Agriculture
American agriculture in the twentieth century underwent immense transformations. The triumphs in agriculture are emblematic of post-war American progress and expansion but do not accurately depict the evolution of American agriculture throughout an entire century of agricultural depression and economic failure. Some characteristics of this evolution are unprecedented efficiency in terms of output per capita, rapid industrialization and mechanization, the gradual slip of agriculture's portion of GNP, and an exodus of millions of farmers from agriculture leading to fewer and larger farms. The purpose of this thesis is to provide an environmental history and political ecology of overproduction, which has lead to constant surpluses, federal price and subsidy intervention, and environmental concerns about sustainability and food safety. This project explores the political economy of output maximization during these years, roughly from WWI through the present, studying various environmental, economic, and social effects of overproduction and output maximization. The complex eco system of modern agriculture is heavily impacted by the political and economic systems in which it is intrinsically embedded, obfuscating hopes of food and agricultural reforms on many different levels. Overproduction and surplus are central to modern agriculture and to the food that has fueled American bodies for decades. Studying overproduction, or operating at rapidly expanding levels of output maximization, will provide a unique lens through which to look at the profound impact that the previous century of technological advance and farm legislation has had on agriculture in America.

A Champion for the Chicano Community: Anita N. Martínez and Her Contributions to the City of Dallas, 1969-1973
Much has been published in Chicano studies over the past thirty to forty years; lacking in the historiography are the roles that Chicanas have played, specifically concerning politics in Dallas, Texas. How were Chicanas able to advance El Movimiento (the Mexican American civil rights movement)? Anita Martínez was the first woman to serve on the Dallas City Council and the first Mexican American woman to be elected to the city council in any major U.S. city. She served on the council from 1969 to 1973 and remained active on various state and local boards until 1984. Although the political system of Dallas has systematically marginalized Mexican American political voices and eradicated Mexican American barrios, some Mexican Americans fought the status quo and actively sought out the improvement of Mexican barrios and an increase in Mexican American political representation, Anita N. Martínez was one of these advocates. Long before she was elected to office, she began her activism with efforts to improve her children’s access to education and efforts to improve the safety of her community. Martinez was a champion for the Chicano community, especially for the youth. Her work for and with young Chicanos has earned her the moniker, “Defender of Dreams.” She created a chicano recreation center in Dallas, as well as various poverty programs and neighborhood beautification projects. Although she has remained relatively unknown, during her tenure on the Dallas City Council, between the years 1969 and 1973, Anita Martínez made invaluable, lasting contributions to the Chicano community in Dallas.
Changes in Gene Expression Levels of the Ecf Sigma Factor Bov1605 Under Ph Shift and Oxidative Stress in the Sheep Pathogen Brucella Ovis
Brucella ovis is a sexually transmitted, facultatively anaerobic, intracellular bacterial pathogen of sheep (Ovis aries) and red deer (Cervus elaphus). Brucella spp. infect primarily by penetrating the mucosa and are phagocytized by host macrophages, where survival and replication occurs. At least in some species, it has been shown that entry into stationary phase is necessary for successful infection. Brucella, like other alphaproteobacteria, lack the canonical stationary phase sigma factor ?s. Research on diverse members of this large phylogenetic group indicate the widespread presence of a conserved four-gene set including an alternative ECF sigma factor, an anti-sigma factor, a response regulator (RR), and a histidine kinase (HK). The first description of the system was made in Methylobacterium extorquens where the RR, named PhyR, was found to regulate the sigma factor activity by sequestering the anti-sigma factor in a process termed "sigma factor mimicry." These systems have been associated with various types of extracellular stress responses in a number of environmental bacteria. I hypothesized that homologous genetic sequences (Bov_1604-1607), which are similarly found among all Brucella species, may regulate survival functions during pathogenesis. To further explore the involvement of this system to conditions analogous to those occurring during infection, pure cultures of B. ovis cells were subjected to environments of pH (5 and 7) for 15, 30, and 45 minutes and oxidative (50mM H2O2) stress, or Spermine NONOate for 60 minutes. RNA was extracted and converted to cDNA andchanges in transcript levels of the sigma factor Bov1605 were measured using qPCR. Preliminary results indicate that under the exposure to Spermine NONOate there was little change in expression, but under oxidative stress expression of the sigma factor Bov1605 was 4.68-fold higher than that expressed under normal conditions. These results suggest that the sigma factor Bov1605 may be involved in oxidative stress defense during …
Characterization of Aprotic Solutes and Solvents Using Abraham Model Correlations
Experimental data were obtained for the computation of mole fraction solubilities of three dichloronitrobenzenes in organic solvents at 25oC, and solubility ratios were obtained from this data. Abraham model equations were developed for solutes in tributyl phosphate that describe experimental values to within 0.15 log units, and correlations were made to describe solute partitioning in systems that contain either "wet" or "dry" tributyl phosphate. Abraham model correlations have also been developed for solute transfer into anhydrous diisopropyl ether, and these correlations fit in well with those for other ethers. Abraham correlations for the solvation of enthalpy have been derived from experimental and literature data for mesitylene, p-xylene, chlorobenzene, and 1,2-dichlorobenzene at 298.15 K. In addition, the enthalpy contribution of hydrogen bonding between these solutes and acidic solvents were predicted by these correlations and were in agreement with an established method. Residual plots corresponding to Abraham models developed in all of these studies were analyzed for trends in error between experimental and calculated values.
Characterization of Arthrobacter Globiformis Aspartate Transcarbamylase Concentrations of Substrates
This thesis consists of one major section with two subsections. The first subsection investigates the activity of Arthrobacter globiformis aspartate transcarbamylase's specific activity with increasing concentrations of the enzyme's substrate. Dihydroorotase (DHOase) activity was also measured with increasing concentrations of the substrate dihydroorotate. The second subsection collected data in order to classify the enzyme, resulting in a classification into the category of class A ATCases with bifunctional ATCase-DHOase complexes. The thesis provides evidence to broaden understanding of the ATCase and DHOase enzymes for members of the family that Arthrobacter belongs to.
