The Strength Of Family Bonds: A Look Into The Lives Of A Family That Has Overcome Adversity And Marginality, Angelique Nevarez Maes

Open Access Theses & Dissertations

In the recent literature that entails the effectiveness of parent/child bonds in deterring children from crime and related deviant activities, little information is mentioned about the effectiveness of Kinship (extended family members) and its possible effectiveness in deterring an individual from crime and related deviant activities. Adverse events such as drug abuse, early death, prostitution and gang activity can plague a family and threaten its unity when parental bonds are absent or non-consistent during adolescence. Marginalities such as poverty and racism take the family unit to the edge of society only serve to further the extent of the damage that …

Experimental Study On The Fabrication Of Advanced Materials For Energy Applications Using High Energy Mechanical Milling, Ashvin Kumar Narayana Swamy

Open Access Theses & Dissertations

The reaction of aluminum (Al) powder with water has the potential for on demand hydrogen generation. Conventional Al powders, however, react with water slowly due to a highly protective oxide layer on the particle surface. Current methods for Al activation involve harmful and expensive materials. The nano-scale Al powders also remain very expensive and have problems such as a large amount of oxide on the surface. The use of aluminum in an energy generation cycle is also hindered by the fact that, although Al is the most abundant metal in the Earth's crust, its recovery from ore consumes a lot …

The Development And Validation Of A Domestic Violence Scale Administered To Ged Program Participants To Determine The Effect On Test Performance, Andres Muro

Open Access Theses & Dissertations

Overwhelming evidence shows that domestic violence is a very serious problem affecting women in the United States. Black et al. (2010) report that approximately 34 million women in the United States, or approximately 30%, have experienced some form of violence including rape, physical, violence, and/or stalking in their lifetimes. Twenty-two percent of the victims have experienced PTSD, 15% have been injured, and 8% have needed medical care. While these statistics show that domestic violence is a serious problem, there are virtually no statistics about the extent to which domestic violence is a barrier to the academic success of Latina immigrant …

An Econometric Approach For Modeling Population Change In Arkansas, David Alexandro Ramirez

Open Access Theses & Dissertations

This study models population in the state of Arkansas using a small econometric model, and is similar to a previous demographic model developed by Fullerton and Barraza de Anda (2008). The components of population change consist of births, deaths, and net migration. Births minus deaths equal natural increase, and population in the current period is population from the previous period plus natural increase plus net migration. Births and deaths are modeled as functions of a one period autoregressive lag as well as national trends. Net migration is also modeled as a one period lag of itself in addition to relative …

Genetic Diversity In Populations Of Epiphanes Chihuahuaensis (Rotifera: Monogononta) In The Northern Chihuahuan Desert, Diego E. Reyes

Open Access Theses & Dissertations

1. Cryptic speciation in zooplankton is a phenomenon that has been recently gaining much attention. This is due in part to advances in molecular techniques which help in the identification of morphologically indistinct species. Organisms that have been traditionally believed to have cosmopolitan distributions are being found to be composed of cryptic species complexes with high levels of genetic divergence among lineages.

2. Epiphanes chihuahuaensis is a member in the Epiphanes senta species complex. In a previous study by Schröder & Walsh (2007), genetic data, along with morphological and reproductive isolation data were employed to help delineate four species within …

Between-Language Repetition Priming In Antonym Generation: Examining Conceptual Encoding And Representation Of Adjectives, Randy Steven Taylor

Open Access Theses & Dissertations

Previous research has shown repetition priming effects between languages, suggesting that a bilingual's two languages share conceptual representation. However these studies have been conducted mainly utilizing concrete nouns as stimuli. In the present study, it was hypothesized that adjectives would produce significant between-language repetition priming. The experiment utilized a 4 (encoding task) X 2 (test language) within-subjects design in which participants (N = 64) encoded words in read only, translation English to Spanish and translation Spanish to English conditions and at test performed an antonym generation task in either Spanish or English. The results revealed that participants were significantly faster …

Effect Of Hafnium-Incorporation On The Microstructure And Dielectric Properties Of Cobalt Ferrite Ceramics, Stephen Josiah Wells

Open Access Theses & Dissertations

The effect of hafnium ion (Hf⁴⁺) incorporation in cobalt ferrite (CFO) was studied. Samples of Hf substituted CFO ceramic (CoFe_2-xHf_xO₄), were synthesized in the laboratory with hafnium concentrations ranging from x=0.000 to x=0.200. X-ray diffraction scans show that the Hafnium CFO crystalizes in the inverse spinel phase. Inclusion of hafnium causes lattice expansion, increasing the lattice parameter from 8.374 í? for pure CoFe2O4 to 8.391 í? for the highest concentration of hafnium tested (x=0.020). The dielectric properties of CFO are greatly enhanced by inclusion of hafnium. The enhancement is due to the …

Cjc: An Extensible Checker For The Cleanjava Annotation Language, Cesar Eduardo Yeep

Open Access Theses & Dissertations

Formal program verification can be used as a complementary technique to software testing. It allows checking the correctness of all the states of a program which may be impossible using only software testing as a verification technique. One software development process that relies on formal verification is Cleanroom Software Engineering. Cleanroom's main principles are to certify the software with respect to its specification and to produce zero-fault or near-zero-fault software. Cleanroom has being tested primarily in safety-critical systems that require a high level of correctness by development teams in places such as NASA and IBM, demonstrating lower fault rates and …

Specifically, its purpose was to gain insight on how enrollment, persistence, and success factors are experienced by female graduate engineering students at a Hispanic Serving Institution located on the U.S.-Mexico border. The topic of underrepresentation of female graduate engineering students is important for higher education practitioners because in spite of the numerous attempts to increase their enrollment in science, technology, engineering and mathematics, their underrepresentation has persisted. The current study is modeled after research conducted by Cordova-Wentling and Camacho (2006). The research question that guides the current study is: …

Comparative Characterization Of Ni-Base Superalloys Fabricated By Laser And Electron Beam Melting Technologies, Krista Amato

Open Access Theses & Dissertations

Nickel-base superalloys have been used in cast and wrought, and powder metallurgy forms for nearly four decades for industrial and automotive applications. One drawback of cast alloys is that upon solidification, there is minimal microstructural control. Another issue to be improved is to eliminate the limitations of shapes and forms of fabricated alloys.

Rapid prototyping is a new technology of additive manufacturing that shows to be promising for the freeform fabrication of novel superalloys, including nickel-base alloys. New rapid manufacturing technologies allow us to produce parts in any shape that can be designed by computer-aided design (CAD) software. Additionally, the …

Optimization Of Stress Wave-Based Nondestructive Methods In Identifying Deterioration In Concrete Structures, Hoda Azari

Open Access Theses & Dissertations

The transportation infrastructure across the United States is deteriorating and requires periodic inspection to predict the cost of repair and extent of maintenance activities, to remedy structural problems, and to ensure safety and serviceability. The use of nondestructive testing (NDT) methods in detecting and characterizing flaws in the infrastructure has become more common. Among different NDT methods, the stress wave-based methods, including ultrasonic surface waves (USW) and impact echo (IE) methods, are widely used to maintain concrete structures. In this dissertation, a complete literature review of seismic wave theory and wave propagation in plate like structures, and stress wave-based methods …

Operation New Dawn: Rhetoric Or Real Policy Change?, Josiah Thomas Barrett

Open Access Theses & Dissertations

Scholars have long explored questions concerning presidential foreign policy decision making as well as military performance in conducting operations. Studies have covered a wide variety of topics, including the organizational dynamics of the military bureaucracy, the effectiveness of military operations, how presidential rhetorical strategies influence the public agenda in foreign affairs, and, in turn, how public opinion influences presidential foreign policy decision-making. Despite these advances, there remains a notable gap in the literature with respect to the relationship between presidential foreign policy objectives and military bureaucratic responsiveness. In particular, when presidents use rhetoric to introduce key shifts in foreign policy …

Supply Chain Management: Impact Of Customer Relationship Marketing On Performance Under Cooperation And Competition Strategies, Maria Eugenia Barua

Open Access Theses & Dissertations

The dissertation investigation proposes a modified supply chain management model that is grounded on marketing theory and the concept of production sharing. Specifically, the model challenges the traditional cooperation-conflict continuum of strategic marketing management with a new managerial approach based on a cooperation-competition continuum. I investigate the significance of the new model in explaining behaviors in the supply chain management and its performance. In addition, I investigate whether the proposed managerial continuum (cooperation-competition) is consistent with other behaviors including power, conflict, trust, and customer relationship marketing such that coordination and supply chain performance is enhanced.

The data collection from manufacturers, …

Modeling The Human Gait Phases Using Granular Computing, Melaku Ayenew Bogale

Open Access Theses & Dissertations

Gait analysis is applied for the provision of diagnosis, evaluation, and for the design of therapeutic intervention for subjects suffering from neurological disorders. The benefits accruing from gait analysis are well established. People with neurological disorders like mild traumatic brain injury, Cerebral Palsy and Multiple Sclerosis, suffer associated functional gait problems. The symptoms and sign of these gait deficits are different from subject to subject and even for the same subject at different stage of the disease. Identifying these gait related abnormalities helps in the treatment planning and rehabilitation process.

The dynamic behavior of gait parameters is cyclic and the …

Size-Dependent Transitions In Grafted Polymer Brushes, Courtney Bosse

Open Access Theses & Dissertations

ABSTRACT

Finding probabilities in order to solve for the most likely configuration of a grafted polymer chain is easily calculated by solving a random walk problem, starting form a given point (the surface). A property of the random walk is used to describe the partition function of a polymer in terms of a sum over possible loops configurations, which simplifies tremendously the problem of calculating the partition function of the grafted polymer. Instead of solving the non-interacting random walk that has been well studied in the theory of the probability, the focus is on the problem of self-interacting random walks, …
