Biomechanical Comparison Of Lower Limb Unloading Between Common Modalities Of Ankle Foot Orthoses, Andrea Blake Wanamaker

Electronic Theses and Dissertations

Tibial stress fractures and other lower extremity injuries can be treated using an ankle foot orthosis (AFO). AFOs are popular because they allow the patient to ambulate somewhat naturally while reducing weight bearing on the injured limb. Despite their popularity, it is currently unclear how well AFOs reduce lower extremity weight bearing.

The first objective of this investigation was to examine the ability of three commonly used ankle foot orthoses to reduce weight bearing within the lower limb by comparing the ground reaction force measured from a force platform to the force measured from an insole pressure measurement device inside …

Emotion Regulation And Threat Estimation As Mediators Of The Relation Between Cognitive Functioning And Anxiety In Late Life, Caroline M. Ciliberti

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Rates of anxiety are generally thought to decline in typically aging older adults. Some theorize that this decline is a result of age-related improvements in emotion regulation. Emotion regulation may require the use of complex cognitive processes, however, which can be impacted by cognitive decline. Indeed, the prevalence of anxiety is high among older adults with cognitive impairment. The current study examined emotion regulation and threat perception as possible mediators in the relation between cognitive functioning and anxiety.;Methods: One hundred adults, aged 60 and older, were recruited from nursing homes, assisted living facilities, and the community. All were asked …

From Sinners To Saints: Emerging Agency In American Women's Novels Before The Civil War, Amy Howard Green

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study investigates the ways in which the narrative of salvation contributed to the development of female selfhood in American women's novels before the Civil War. Over time, protagonists of some of the most popular of these novels were transformed from victims of seduction (as in Charlotte Temple or The Coquette) into self-reliant agents of virtue (as in The Wide, Wide World or The Lamplighter). Such a depiction suggests that a similar shift in readers' imaginations of their own selfhood was also taking place, and it paralleled changes in the genre conventions of novels that have been traditionally identified as …

Effectiveness Of A Theory Based Comprehensive Sexual Education Program At A Baltimore City High School, Darlene Hinds

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background Sexual activity among adolescents can have lifelong consequences including teen pregnancy and sexually transmitted infections. The Youth Risk Behavior Surveillance Survey (YRBSS), reported 13.8% of high school students grades 9-12 admitted to having intercourse with four or more people and 34.2% report being sexually active (CDC, 2010b). Baltimore City has disproportionately high rates related to teen pregnancy, chlamydia and gonorrhea when compared to national statistics. In 2006, the rate of teen births among girls ages 15-19 in Baltimore City was 66.4 per 1,000, compared to Maryland's teen birth rate of 34.4 per 1,000 (Maryland Department of Health and Mental …

Development Of Synthetic Pathways For Carbon Nanohoops, Yiwei Huang

Graduate Theses, Dissertations, and Problem Reports (ETD)

A synthetic pathway was developed for the preparation of a precursor of a [6]cycloparaphenylene derivative, which represents the shortest repeating carbon nanohoop segment of an armchair (6,6) carbon nanotube. As a key intermediate of the synthetic sequence, trans,trans-1,4-di(4-bromophenyl)-1,3-butadiene was synthesized by using the Homer-Wadsworth-Emmons reaction between 4-bromocinnamaldehyde and diethyl 4-bromobenzylphosphonate reported in the literature. The use of BF3˙OEt2 as a Lewis acid for the Lewis acid-catalyzed Diels-Alder reaction between trans,trans-1 ,4- di(4-bromophenyl)-1,3-butadiene and 1,4-benzoquinone was successful in producing cis-5,8-di(4-bromophenyl)-5,8-dihydro-1 ,4-naphthalenediol. The Diels-Alder reaction ensures that the two 4-bromophenyl substituents are cis to each other in the sixmembered ring, which is …

Network Dynamics, Synchronization, And Self-Propelled Particles In Chemical Systems, Hua Ke

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neural networks are a class of biological networks of great importance. They are a key component of the central nervous system that coordinates body functions. The exploration of the detailed mechanism of biological neural networks remains extremely active. Inspired by the structure of biological neural networks, artificial neural networks have been designed to solve a variety of problems in pattern recognition, prediction, optimization and control. However, few studies have been reported that explore the dynamics of biological neural networks using chemical systems. As part of this thesis, an experimentally trainable network based on the photosensitive Belousov-Zhabotinsky reaction is developed, where …

Thrombelastography Parameters Versus Classical Coagulation Profile In Trauma Patients: A Retrospective Study, Abdulraouf Y. Lamoshi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The West Virginia University Guide to the Preparation of Masters Theses Abdulraouf Y. Lamoshi Thrombelastography Parameters versus Classical Coagulation Profile in Trauma Patients: a Retrospective Study Background: Thrombelastography (TEGTM, Hemoscope, Niles, IL) is increasingly utilized. As TEG depicts overall coagulation it may be more comprehensive and capable to detect any coagulation abnormalities in comparison to classical coagulation tests (CCT: PT, PTT, INR, platelets). Traumatic brain injury (TBI) is thought to contribute to coagulopathy. The primary aim was to compare TEG parameters of TBI vs. Non-TBI patients. The secondary aim was to identify TEG vs. CCT parameters associated with outcome (mortality, …

Characterization Of Late Postpartum Sleep Disturbance, Caffeine-Related Performance, And Daily Functioning, Kelsey K. Meekins

Graduate Theses, Dissertations, and Problem Reports (ETD)

The early postpartum period is marked by maternal sleep fragmentation and performance deficits. Although sleep gradually improves in postpartum women, reaction times gradually worsen. This performance deficit is seen beyond 6 weeks postpartum, when many women are expected to return to work, and it is unknown when (or if) new mothers' performance deficits fully recover. The current study used existing data to characterize the late postpartum period (6 months-3 years after the child was born) in terms of recovery from sleep disturbance by monitoring the behavior of mothers on both objective and subjective measures. The current study aimed to describe …

The study involves the analysis of engine and chassis dynamometer data collected from different engine technologies and chassis dynamometer test cycles in order compare the variability in gravimetric PM mass as well as the PM mass estimated by number-concentration.;PM and oxides of nitrogen (NOx) have …

The Influence Of Memory Enhancement Techniques On Source Monitoring, Ria M. Travers

Graduate Theses, Dissertations, and Problem Reports (ETD)

An important aspect of accurate eyewitness testimony is not only being able to recall the details of an event, but being able to trace that memory back to its source or origin (Johnson, Hashtroudi, & Lindsay, 1993). The current study examined the use of two memory enhancement interventions to improve the accuracy of source memory, or the correct attribution of a memory to its origin, and free recall. The first intervention, motivational instructions, informed participants that they are capable of recalling an event if they try their best. The second intervention, focused meditation, used a breathing exercise to focus individuals' …

Tuning The Electrical And Thermal Conductivities Of Thermoelectric Oxides Through Impurity Doping, Maria A. Torres Arango

Graduate Theses, Dissertations, and Problem Reports (ETD)

Waste heat and thermal gradients available at power plants can be harvested to power wireless networks and sensors by using thermoelectric (TE) generators that directly transform temperature differentials into electrical power. Oxide materials are promising for TE applications in harsh industrial environments for waste heat recovery at high temperatures in air, because they are lightweight, cheaply produced, highly efficient, and stable at high temperatures in air. Ca3Co4O9(CCO) with layered structure is a promising p-type thermoelectric oxide with extrapolated ZT value of 0.87 in single crystal form [1]. However the ZT values for the polycrystalline ceramics remain low of ∼0.1-0.3. In …

Investigating The Effect Of Humor Communication Skills Training On Pro-Social And Anti-Social Humor Styles, Cognitive Learning, Self-Efficacy, Motivation, And Humor Use, Lori E. Vela

Graduate Theses, Dissertations, and Problem Reports (ETD)

Humor is an important aspect of interpersonal interactions as it is linked to the development and maintenance of relationships (Merolla, 2006). The purpose of this dissertation was to test the effect of a humor communication skills training program on the ability to minimize anti-social humor (i.e., aggressive, self-defeating) and enhance pro-social humor (i.e., affiliative, self-enhancing) in interpersonal interactions. Working from the framework of Social Cognitive Theory (Bandura, 1986, 2001), the effect of the humor skills training on self-efficacy, motivation, positive and negative humor use, and cognitive learning were also examined. Data were collected at baseline, post-training, and at a two …

Evaluation Of The Effects Of Aggregate Gradation And Compaction Effort On The Voids In Mineral Aggregate In Asphalt Concrete, Logan Bessette

Graduate Theses, Dissertations, and Problem Reports (ETD)

Asphalt concrete should resist short-term rutting, provide resistance to thermal cracking, and maintain structural integrity through the design life of the structure. Balancing these factors is achieved by ensuring adequate asphalt binder in a strong aggregate structure. The design asphalt content is decreased by applying additional compaction effort in the form of increased gyrations in the Superpave Gyrator Compactor. The mixes that undergo increased compaction effort present decreased fatigue life, although they resist short-term rutting. Mixes that undergo less compaction effort contain more binder and have long fatigue lives, although they are susceptible to rutting.;Two hypotheses were tested to determine …

What Is The Meaning Of Like: The First Amendment Implications Of Social-Media Expression, Ira Robbins

Scholarly Articles in Law Reviews & Journals

Everywhere the Internet goes, new legal problems are sure to follow. As social media expands and infiltrates our daily lives, society must grapple with how to extend the law to modern situations. This problem becomes increasingly pressing as more and more of our social interactions take place online. For example, Facebook has become a colossal gathering place for friends, families, co-workers, frenemies, and others to disseminate their ideas and share information. Sometimes Facebook replaces old institutions; other times it augments them. Where once a neighbor would show allegiance to a political candidate by staking a sign on the front lawn, …

Reimagining The Law Of Self-Employment: A Comparative Perspective, Jayesh Rathod, Michal Skapski

Scholarly Articles in Law Reviews & Journals

U.S. employment law has traditionally disfavored bright-line rules to distinguish between traditional “employees” and independent contractors, instead relying on more flexible criteria, to be applied on a case-by-case basis. This fluidity has enabled employers to structure these relationships – and the corresponding bundle of worker rights and benefits – in ways that serve their own material and normative interests. Indeed, recent employment law literature has noted a dramatic shift towards independent contracting and contingent worker schemes in the U.S., even when the actual workplace dynamics are more akin to an employer-employee relationship. These same trends are now visible on the …

Informal Deference: A Historical, Empirical, And Normative Analysis Of Patent Claim Construction, Jonas Anderson, Peter S. Menell

Scholarly Articles in Law Reviews & Journals

Patent scope plays a central role in the operation of the patent system, making patent claim construction a critical aspect of just about every patent litigation. With the resurgence of patent jury trials in the 1980s, the allocation of responsibility for interpreting patent claims between trial judge and jury emerged as a salient issue. While the Supreme Court’s Markman decision usefully removed claim construction from the black box of jury deliberations notwithstanding its "mongrel" mixed fact/law character, the Federal Circuit's adherence to the view that claim construction is a pure question of law subject to de novo appellate review produced …

Economics And Politics: Perspectives On The Goals And Future Of Antitrust, Jonathan Baker

Scholarly Articles in Law Reviews & Journals

This article examines the roles of economics and politics in U.S. antitrust from several perspectives. It explains why the modern debate over the economic welfare standard that enforcers and courts should pursue is unsatisfying. It connects economics and politics by describing antitrust’s economic goals as the product of a mid-20th century political understanding about the nature of economic regulation that has continued in force to this day. To protect that understanding, it explains, antitrust rules should now be implemented using a qualified consumer welfare standard. The article also identifies contemporary political tensions that threaten to create regulatory gridlock, or even …

'No Body Left Behind': Re-Orienting School-Based Childhood Obesity Interventions, Lindsay Wiley

Scholarly Articles in Law Reviews & Journals

Although there are now laws on the books in virtually every jurisdiction aimed at addressing childhood obesity in K-12 schools, these efforts are inadequate and may even be misguided in important ways. Efforts aimed at health promotion - through healthier eating and increased physical activity - remain woefully underfunded even as they proliferate at every level of government. It is one thing to enact a requirement that all schools offer a minimum number of minutes of physical education each week or that school lunches include more fruits and vegetables. But it is quite another to make the budgetary commitment to …

Lessons From Personhood's Defeat: Abortion Restrictions And Side Effects On Women's Health, Maya Manian

Scholarly Articles in Law Reviews & Journals

State personhood laws pose a puzzle. These laws would establish fertilized eggs as persons and, by doing so, would ban all abortions. Many states have consistently supported laws restricting abortion care. Yet, thus far no personhood laws have passed. Why? This Article offers a possible explanation and draws lessons from that explanation for understanding and resisting abortion restrictions more broadly. I suggest that voters’ recognition of the implications of personhood legislation for health issues other than abortion may have led to personhood’s defeat. In other words, opponents of personhood proposals appear to have successfully reconnected abortion to pregnancy care, contraception, …

Law And Ethics For Autonomous Weapon Systems: Why A Ban Won't Work And How The Laws Of War Can, Kenneth Anderson, Matthew Waxman

Scholarly Articles in Law Reviews & Journals

Stanford University, The Hoover Institution (Jean Perkins Task Force on National Security and Law Essay Series) American University Washington College of Law Research Paper No. 2013-11 Columbia Public Law Research Paper 13-351 Abstract: Public debate is heating up over the future development of autonomous weapon systems. Some concerned critics portray that future, often invoking science-fiction imagery, as a plain choice between a world in which those systems are banned outright and a world of legal void and ethical collapse on the battlefield. Yet an outright ban on autonomous weapon systems, even if it could be made effective, trades whatever risks …

Ideology And Decision Making In School-Based Counseling, Michelle Klein Brenner

Dissertations, Theses, and Capstone Projects

The present study built on the design and results from the pilot study in an attempt to explore the relationship between psychologists' personal ideologies and the decisions they make in school-based counseling. Of particular interest was whether higher levels of self-reported ideology were related to support of relevant school policies. Participants included 166 psychologists who responded to an online survey that included questions related to personal and professional ideologies, attitudes toward school policies, training and preparedness in four areas of interest, and hypothetical scenarios. Consistency among responses in areas including theoretical orientation, political party, and training and preparedness in ethics …

Hypertension Knowledge, Expectation Of Care, Social Support, And Adherence To Prescribed Medications Of African Americans With Hypertension Framed By The Roy Adaptation Model, Andrea Maria Grant

Dissertations, Theses, and Capstone Projects

Hypertension (HTN) prevalence in African Americans contribute to higher rates of disabilities and deaths from stroke, myocardial infarction, and end stage renal disease than all other racial groups in the United States. The major reason documented for these poor health outcomes is related to lower HTN control rates among African Americans compared to other racial/ethnic groups. Though overall HTN awareness, pharmacological treatments and control have significantly improved for all populations, studies found that rates of HTN control and adherence with anti-hypertensive medications are lower for African Americans compared to other subgroups.

Energy Of The Quasi-Free Electron In Repulsive Atomic And Molecular Fluids, Yevgeniy Lushtak

Dissertations, Theses, and Capstone Projects

The ability to predict accurately the energy V₀(ρ) of the quasi-free electron along the entire density (ρ) range of a supercritical fluid has applications in determining the ideal thermodynamic conditions for chemical reactions involving charged species. The previously established field ionization method of extracting V₀(ρ) from the fluid density dependent shift Δ(ρ) in the ionization energy of a dopant molecule has led to the discovery of a novel effect on V₀(ρ) occurring near the critical isotherm of the fluid. Unfortunately this method has limitations in determining V₀(ρ) in fluids with low critical …

Neurophysiological Indices Of The Effect Of Cognates On Vowel Perception In Late Spanish-English Bilinguals, Carol A. Tessel

Dissertations, Theses, and Capstone Projects

The field of research in bilingualism and second language (L2) acquisition has yielded overwhelming evidence that acquiring a second language later in life will result in less accurate production and perception of consonants and vowels in the second language. These effects, in part, are a result of interference from the already formed phonetic categories shaped by early exposure to the L1 (Iverson, 2007). Phonetic categories from the L2 will, at least initially, be mapped onto phonetic categories from the L1 (Flege, 1995). Shared storage of similar lexical items from L1 and L2 may also take place resulting in differences in …

Cafeteria, Commissary And Cooking: Foodways And Negotiations Of Power And Identity In A Women’S Prison, Amy Brooks Smoyer

Dissertations, Theses, and Capstone Projects

This study uses foodways theory to build knowledge about the lived experience of incarceration by analyzing women’s narratives about prison food and eating. Semi-structured interviews were conducted with 30 formerly incarcerated women in New Haven, CT. The interviews were digitally recorded and transcribed. Findings explain the different ways that inmates collect, prepare, distribute and consume food, and the centrality of these activities to incarcerated life. By shedding light on these daily routines, the world of prison life comes into greater focus.

Thematic analysis of the data further illuminates the prison experience by suggesting the positive and negative ways that food …

(In)Justice On The Streets: The Long Housing Crisis In Hungary From Above And Below, Éva Tessza Udvarhelyi

Dissertations, Theses, and Capstone Projects

Hungary today is the only country in the world that has encoded in its constitution the possibility of penalizing homelessness in public spaces. The intensity of criminalization of homelessness in recent years has given rise to a tug-of-war between the ruling party and grassroots activists. This dissertation explores the politics of homelessness in Budapest from three interlocking perspectives, drawing on primary historical sources, social science literature in English and Hungarian, the secondary analysis of a participatory action research project as well as the author’s experiences as a housing rights activist. It will first examine how the state has addressed homelessness …

Script Fading For Children With Autism: Generalization Of Social Initiation Skills From School To Home, Alison Marie Wichnick

Dissertations, Theses, and Capstone Projects

A critical component of teaching social skills to people with autism is the generalization of behavior change across a variety of untrained situations during which social skills are appropriate. The script-fading procedure is an effective technology for teaching social skills to people with autism, but few researchers have established cues in the natural environment as the discriminative stimuli for social initiations. The purpose of this study was to use a script-fading procedure to teach young children with autism to initiate to one another across various activities in the school setting, and to program for generalization across untrained stimuli in the …

Uv-Visible Microscope Spectrophotometric Polarization And Dichroism With Increased Discrimination Power In Forensic Analysis, Dale Kevin Purcell

Dissertations, Theses, and Capstone Projects

Microanalysis of transfer (Trace) evidence is the application of a microscope and microscopical techniques for the collection, observation, documentation, examination, identification, and discrimination of micrometer sized particles or domains. Microscope spectrophotometry is the union of microscopy and spectroscopy for microanalysis. Analytical microspectroscopy is the science of studying the emission, reflection, transmission, and absorption of electromagnetic radiation to determine the structure or chemical composition of microscopic-size materials. Microscope spectrophotometry instrument designs have evolved from monochromatic illumination which transmitted through the microscope and sample and then is detected by a photometer detector (photomultiplier tube) to systems in which broad-band (white light) illumination …

Free From Jazz: The Jazz And Improvised Music Scene In Vienna After Ossiach (1971-2011), Thomas Albert Zlabinger

Dissertations, Theses, and Capstone Projects

Focusing on a diverse and eclectic scene that is under-documented, this dissertation investigates the historical, social, and cultural aspects of jazz and improvised music in Vienna over the last four decades. Through fieldwork, I have observed various characteristics and trends regarding the jazz and improvised music scene in Vienna and have subsequently organized the musicians and their recordings into seven fluid "fields": Traditional-U.S. Performance, Post-Tradition, DJ/Hip-Hop, Volk/Ethnic, Cabaret, Unclassified, and Abroad. One of the most striking aspects of the entire scene is the near-absence of a racialized discourse among musicians and critics and of stereotypical markers of "blackness" in performance. …
