Using ethnographic research in the form of an outcomes assessment, this project aims to unpack and evaluate the experiences of students and significance of the key concepts shared during the Live Algoma-Improvement Science course/and associated projects during the 2015-2016 and 2016-2017 school years. Through the use of evaluative techniques such as interviews, focus groups, and a survey, I endeavor to both strengthen and inform the work Live Algoma is doing and highlight to the community and other stakeholders the valuable impact of this initiative on the students. As part of the Improvement Science course, students from the Algoma School District were trained on key concepts such as failing forward, PDSA, and ways of being to empower them to better handle individual project management, life challenges, and goal setting. While this project was expansive in overall scope, this outcome evaluation sought to understand the retention and internalization by program participants of key concepts imparted from the Improvement Science course and related projects. The findings provide strategic and targeted insights into the success of the course and opportunities for refinements in future Improvement Science courses and school and community projects with Live Algoma and the Algoma School District.

The purpose of this study was to explore athletic identity, identity foreclosure, and career maturity in a sample of undergraduate college students currently enrolled in kinesiology and physical education classes at a university in the southern United States. Students were provided with an internet link that requested them to complete a demographic survey, the Athletic Identity Measurement Scale (AIMS), the foreclosure subscale of the Extended Objective Measure of Ego Identity Status, and the Attitude Scale (Form A-2) of the Career Maturity Inventory. Examination of the Pearson moment correlations indicated that the higher the sport participation during high school, the greater the athletic identity and identity foreclosure, and lower the career maturity attitudes. ANOVAs were performed to examine differences between males (n = 123) and females (n = 183), kinesiology (n = 181) and non-kinesiology majors (n = 125), and white (n = 144) and non-white students (n = 162) on athletic identity, identity foreclosure, and career maturity. Results showed that males scored significantly higher on athletic identity and identity foreclosure, and significantly lower on career maturity than females. Kinesiology students had scores significantly higher on athletic identity and identity foreclosure, and lower on career maturity. Finally, individuals that identified their …

This study examines changes over time in 40 different Sherlock Holmes films and 39 television series and movies spanning from 1900 to 2017. Quantitative observations were mixed with a qualitative examination. Perceptions of law enforcement became more positive over time, the types of crime did not vary, and representation of race and gender improved over time with incrementally positive changes in the representation of queer, mentally ill, and physically handicapped individuals. The exact nature of these trends is discussed. Additionally, the trends of different decades are explored and compared. Sherlock Holmes is mostly used as a vehicle for storytelling rather than for the salacious crimes that he solves, making the identification of perceptions of crime in different decades difficult. The reasons for why different Sherlock Holmes projects were created in different eras and for different purposes are discussed.

This investigation was a post-hoc, quantitative analysis of secondary academic performance and participation choices of Hispanic students. Three years of longitudinal student-level data was collected to examine the likelihood of college enrollment based on college and career readiness (CCR) factors. At the time of the study, CCR was defined as qualifying exam scores, credit for at least two advanced/dual enrollment courses, or enrollment in a career and technology education (CTE) coherent sequence of courses. Research participants (N = 803) consisted solely of Hispanic high school graduates from the 2014 cohort. Frequency statistics indicate 45.5% (n = 365) attended an institute of higher education (IHE) within 2 years of high school graduation. Findings reveal Hispanic females were more likely than Hispanic males to meet CCR indicators as well as postsecondary resiliency outcomes. Analysis of chi-square tests of independence suggests a moderately strong association exists between CCR indicators and postsecondary participation among high school graduates. Differences were found in terms of gender and postsecondary enrollment, x^2(6) = 24.538, p < .001. Differences were also found in terms of type of IHE and postsecondary resiliency, x^2(3) = 34.373, p < .001. More Hispanic CCR graduates enrolled at 2-year and 4-year IHE than expected …

Acrolein is produced endogenously after traumatic brain injury (TBI) and is considered a primary mechanism for secondary damage occurring after TBI. We are using frontal cortex networks derived from mouse embryos and grown on microelectrode arrays in vitro to monitor the spontaneous activity of networks and the changes that occur after acrolein application. Networks exposed to acrolein exhibit a biphasic response profile. An initial increase in network activity, followed by a decrease to 100% activity loss in applications ≥ 50 µM. In applications below 50 µM, acrolein was not toxic but generated activity instability with coordinated but irregular population busts lasting for up to 6 days. The increase in activity preceding toxicity may be linked to a decrease in free spermine, a free radical scavenger that modulates Na+, K+, Ca+ channels as well as NMDA, Kainate, and AMPA receptors. Action potential wave shape analysis after 20 and 30 µM acrolein application revealed a concentration-dependent 15-33% increase in peak to peak amplitude within minutes after exposure. For the same concentrations of acrolein (50 µM), the time required to reach 100% activity loss (IT100) was longer in serum-free medium than in medium with 5% serum, in which IT100 values were reduced by …

This research study is conducted to test Workman, Fiszman, Rindflesch and Nahl's information flow-serendipitous knowledge discovery (IF-SKD) model of information behavior, in a clinical care context. To date, there have been few attempts to model the serendipitous knowledge discovery of physicians. Due to the growth and complexity of the biomedical literature, as well as the increasingly specialized nature of medicine, there is a need for advanced systems that can quickly present information and assist physicians to discover new knowledge. The National Library of Medicine's (NLM) Lister Hill Center for Biocommunication's Semantic MEDLINE project is focused on identifying and visualizing semantic relationships in the biomedical literature to support knowledge discovery. This project led to the development of a new information discovery system, Spark. The aim of Spark is to promote serendipitous knowledge discovery by assisting users in maximizing the use of their conceptual short-term memory to iteratively search for, engage, clarify and evaluate information presented from the biomedical literature. Using Spark, this study analyzes the IF- SKD model by capturing and analyzing physician feedback. The McCay-Peet, Toms and Kelloway's Perception of Serendipity and Serendipitous Digital Environment (SDE) questionnaires are used. Results are evaluated to determine whether Spark contributes to physicians' serendipitous …

This study uses the predictive modeling program Sea-Levels Affecting Marshes Model (SLAMM) to evaluate sea-level rise hazards, such as erosion and inundation, on coastal archaeological sites with a vertical rise of sea level of .98 meters from 2006 to 2100. In total 177 archaeological site locations were collected and georeferenced over GIS outputs maps of wetlands, erosion presence, surface elevation, and accretion. Wetlands data can provide useful information about characteristics of the wetland classes, which make a difference in the ability for coastal archaeological sites to combat sea level rise. Additionally, the study evaluated predicted erosion of archaeological sites by presence or absence of active erosion on a cell-by-cell basis. Elevation map outputs relative to mean tide level allowed for a calculation of individual archaeological site datums to use NOAA tidal databases to identify the potential for their inundation. Accretion maps acquired from the SLAMM run determined the potential for the archaeological site locations to combat rising sea levels and potentially provide protection from wave effects. Results show that the most significant hazard predicted to affect coastal archaeological sites is inundation. Approximately 54% of the total archaeological sites are predicted to be inundated at least half the time by 2100. …

Auditions often require performance of orchestral excerpts as part of the screening process because orchestral literature contains a wealth of technical challenges at different levels of difficulty; however, many cello teachers still only use etudes, sonatas, and concertos for musical development and technical application and do not use orchestral excerpts as pedagogical tools or daily exercises. This dissertation, in an effort to standardize orchestral excerpts as part of common technical exercises, includes the ten most popular major excerpts selected from thirty audition lists from major orchestras in the United States. Analysis of each excerpt highlights different technical elements, provides short exercises to overcome these challenges, and discusses the aspects of cello playing that will benefit most from practicing orchestral excerpts. In this way, these selections can be played in preparation for auditions, as well as incorporated into daily practice routines.

How does state capacity affect the state's ability to intervene in events of communal violence? Communal violence is conflict that occurs between two non-state groups that share a communal identity. The state controls the monopoly on the use of force, so it should be expected that the state will control these violent events. Research on intervention has shown that a state's military is an important indication of their ability to intervene. The study of other elements of state capacity such as the bureaucracy and political institutions have been largely ignored as factors to explain intervention. This paper builds on these elements of state capacity to argue that intervention can be explained by the state's military, bureaucracy, and the institutions that are in place. This argument has support from an empirical analysis conducted through replication data in Sub-Saharan Africa from 1989 to 2010.

This thesis presents the implementation of some of the basic concepts of digital logic design in a fun and creative way with the help of paper electronics. This involves circuit building on paper using conductive tape or conductive ink and circuit components as electronics craft materials. Paper electronics toolkit called circuit sticker microcontroller which is deployed by a company named Chibitronics and AT89C51 microcontroller were used for the computational functioning of the circuits built on paper. This can be used to teach the fundamentals of digital logic design to the students in their early stage of studies in an attractive way and can help them them gain a better understanding. This thesis can also be helpful in grabbing the attention of high school students and motivate them towards choosing the engineering discipline for their higher studies.

The rapid advancement of web and mobile application technologies has recently posed numerous challenges to the Software Engineering community, including how to cost-effectively test applications that have complex event spaces. Many software testing techniques attempt to cost-effectively improve the quality of such software. This dissertation primarily focuses on that of hybrid test suite prioritization. The techniques utilize two or more criteria to perform test suite prioritization as it is often insufficient to use only a single criterion. The dissertation consists of the following contributions: (1) a weighted test suite prioritization technique that employs the distance between criteria as a weighting factor, (2) a coarse-to-fine grained test suite prioritization technique that uses a multilevel approach to increase the granularity of the criteria at each subsequent iteration, (3) the Caret-HM tool for Android user session-based testing that allows testers to record, replay, and create heat maps from user interactions with Android applications via a web browser, and (4) Android user session-based test suite prioritization techniques that utilize heuristics developed from user sessions created by Caret-HM. Each of the chapters empirically evaluate the respective techniques. The proposed techniques generally show improved or equally good performance when compared to the baselines, depending on an …

The Divine Coming of the Light is a memoir-in-essays that covers an experience, from 2007 to 2010, when I lived in Kosuge Village (population 900), nestled in the mountains of central Japan. I was the only foreigner there. My memoir uses these three years as a frame to investigate how landscape affects identity. The book profiles who I was before Japan (an evangelical and then wilderness guide), why I became obsessed with mountains, and the fall-out from mountain obsession to a humanistic outlook. The path my narrator takes is one of a mountain hike. I was born in tabletop-flat West Texas to conservative, Christian parents in the second most Republican county by votes in America. At 19, I made my first backpacking trip to the San Juan Mountains of western Colorado and was awed by their outer-planetary-like massiveness. However, two friends and I became lost in the wilderness for three days without cell phones. During this time, an obsession possessed me as we found our way back through the peaks to safety, a realization that I could die out there, yes, but amid previously unknown splendor. I developed an addiction to mountains that weakened my religious faith. Like the Romantic …

The aim of this study was to understand the processing – structure – property relationships in spark plasma sintered (SPS) boron carbide (B4C) and B4C-titanium diboride (TiB2) ceramic composites. SPS allowed for consolidation of both B4C and B4C-TiB2 composites without sintering additives, residual phases, e.g., graphite, and excessive grain growth due to long sintering times. A selection of composite compositions in 20% TiB2 feedstock powder increments from 0% to 100%, was sintered at 1900°C for 25 minutes hold time. A homogeneous B4C-TiB2 composite microstructure was determined with excellent distribution of TiB2 phase, while achieving ~99.5% theoretical density. An optimum B4C-23 vol.% TiB2 composite composition with low density of ~3.0 g/cm3 was determined that exhibited ~30-35% increase in hardness, fracture toughness, and flexural bend strength compared to commercial armor-grade B4C. This is a result of a) no residual graphitic carbon in the composites, b) interfacial microcrack toughening due to thermal expansion coefficient differences placing the B4C matrix in compression and TiB2 phase in tension, and c) TiB2 phase aids in crack deflection thereby increasing the amount of intergranular fracture. Collectively, the addition of TiB2 serves as a strengthening and toughening agent, and SPS shows promise for the manufacture of hybrid ceramic …

Soil moisture information can be used accurately in determining the timing and amount of irrigation applied to plants. Pan and Pan et al. proposed a robust and simple daily diagnostic equation for estimating daily soil moisture. The diagnostic equation evaluates the relationship between the soil moisture loss function and the summation weighted average of precipitation. The loss function uses the sinusoidal wave function which employs day of the year (DOY) to evaluate the seasonal variation in soil moisture loss for a given year. This was incorporated into the daily diagnostic equation to estimate the daily soil moisture for a location. Solar radiation is an energy source that drives the energy and water exchanges between vegetation and the atmosphere (i.e., evapotranspiration), and thus impacts the soil moisture dry-down. In this paper, two parameters (the actual solar radiation and the clear sky solar radiation) are introduced into loss function coefficient to improve the estimation of soil moisture. After the Introduction of the solar radiation data into soil moisture loss function, a slight improvement was observed in the estimated daily soil moisture. Pan observed that generally the correlation coefficient between the estimated and the observed soil moisture is above 0.75 and the root …

The purpose of this thesis is to examine idiomatic structures with ki in the ki-wo [transitive verb] and ki-ga [intransitive verb] constructions. It is argued that for Japanese language learners, it is crucial to be able to understand and produce ki idioms, because they are frequently used in everyday speech. There are often misconceptions regarding ki in the West for those who are fans of Japanese culture due to the influence of martial arts and anime, which paint ki as a spiritual energy that can be controlled and developed. However, upon examining the above mentioned idiomatic structures with ki, it is clear that ki can be expressed as both controllable by the subject of ki (transitive), as well as a thing that acts of its own accord and is spontaneous (intransitive). This thesis somewhat corroborates the studies of W. M. Jacobson, Zoe Pei Sui Luk , and Yoshihiko Ikegami by arguing that intransitive constructions are often used in Japanese, and examining both transitive and intransitive expressions with ki is significant to understanding the meanings produced in ki expressions. It is hoped that analyzing 37 transitive and intransitive idiomatic structures with ki will help Japanese language learners not only understand the …

Skeletal muscle satellite cells are important for muscle repairing and muscle mass growth. For a successful muscle regenerative process, satellite cells have to sequentially undergoing different stages of myogenic process, i.e. proliferative state and differentiation state. To support this process, the presence of different circulating factors, such as immune cells, cytokines, and hormones, at the appropriate time course is critical. Among these factors, hormones, such as testosterone, cortisol, and IGF-1, have shown to play an important role in satellite cell proliferation and differentiation. Studies investigated the effect of testosterone on satellite cell using a supraphysiological dose in human or in cell culture demonstrated that testosterone is critical in satellite cell myogenic process. Due to the anabolic effect of testosterone on muscle, studies had been focused on the physiological means to increase the circulating testosterone concentration in the body to maximize the muscle mass growth from resistance exercise. The acute and transient increase in testosterone has shown to be beneficial to muscle mass growth and strength gain; however, this change in physiological testosterone concentration on satellite cell myogenesis is not known. Therefore the purpose of this dissertation is to first determine the effect of acute change in exercise-induced hormones on satellite …

Isolating novel phages using Streptomyces azureus, which produces antibiotic thiostrepton, as a host, and characterizing the genomes may help us to find new tools that could be used to develop antibiotics in addition to contribute to the databases of phages and specifically, Streptomyces phages. Streptomyces phages Alsaber, Omar, Attoomi, Rowa, and ZamZam were isolated using during this study. They were isolated from enriched soil and sequenced by Illumina sequencing method. They were isolated from three different geographical regions. They are siphoviridae phages that create small clear plaques with a diameter of approximately 0.5-1 mm, except for Rowa which has cloudy plaques, and they have varied sizes of their heads and tails. ZamZam was not characterized at this time. The sequencing shows that they are circular genome with 3' sticky overhang and various genomes' sizes with high percentage of GC content with the average of 66%. Alsaber was classified under sub-cluster BD3, while Omar was categorized under sub-cluster BD2. They share the same cluster of Cluster BD. Rowa was placed in Cluster BL and Attoomi is currently a singleton that does not fit into an established cluster. Alsaber yields 76 putative genes with no tRNA, Omar 81 putative genes with 1 …

This dissertation attempts to answer how social and economic mechanisms operate in individual, community and state levels to impact volunteering. Both social processes and economic factors significantly impact the amount of volunteering. However, researchers have a tendency to explain volunteering only by one of these factors. As both theories are equally important in explaining volunteerism, the development of a coherent theory is necessary to combine economic and social theories. This dissertation suggested that, when evaluated together, the influences of the economic factors on volunteering diminish as individuals get more connected with the other members of the society. The three-level analysis of the volunteering largely supports the primary hypothesis of the dissertation that economic concerns for volunteering are crowded out when individuals or the society is highly connected. This finding can help practitioners design better strategies to enhance volunteering such as creating opportunities for the members of the society to interact with each other.

Understanding information technology and its related products and services is increasingly important because the everyday use of technology continues to expand and broaden. Despite this need for greater understanding, the extant theories that explore the dominant factors that drive intention to use a new technology are limited. The Technology Acceptancy Model (TAM) is the most popular model in explaining traditional technology adoption. The limitations of the TAM in grasping the overall evaluation of technology or service are one of motivations for developing new models in this dissertation. The two antecedents of the TAM- perceived usefulness and perceived ease of use- only capture partial utility of a service (or product). In addition, some researchers argued that key factors used in an initial acceptance model such as perceived usefulness and perceived ease of use are not strong predictors of future continuance intention of the service because they do not consider future switching intention in the later stage. Hence, one goal of this dissertation is to develop and test new models to predict factors that drive intention and continuance intention decisions of new technology related products or services. This research involves three studies that examine different aspects of adoption and continuance intention decisions …

A population survey was conducted on the mosquito species recorded in Denton, Texas for the years of 2005 to 2015. Data used in this project were obtained from an ongoing, long-term surveillance program led by the City of Denton and conducted through the University of North Texas. Research focused on the population dynamics and community structure of mosquitoes collected within urban areas of Denton, Texas in relation to certain environmental variables. A total of 80,837 female mosquitoes were captured and represented 38 species found under the following genera: Aedes, Anopheles, Coquillettidia, Culex, Culiseta, Mansonia, Orthopodomyia, Psorophora, Toxorhynchites, and Uranotaenia. Culex quinquefasciatus was the most abundant species followed by Aedes vexans. Seasonal patterns of the most abundant species revealed high variability throughout the study. Container breeders were most abundant in August and those that breed in floodwaters were most abundant in the months of May and September. Samples were tested for arbovirus presence through the Texas Department of State Health Services in Austin, Texas and multiple pools tested positive for West Nile virus throughout the study. Stepwise multiple regression and Spearman's rank correlation analyses were performed to examine the relationship between the mosquito community and environmental variables. Data revealed that temperature, …

We hypothesized that the formation of malevolent introjects undermines the development of self-compassion, which in turn produces greater feelings of shame. We hypothesized that these feelings of shame account for concurrent depressive symptoms in adulthood. To test these hypotheses, we proposed a multiple mediator mediation model in which our independent variable was childhood maltreatment. We modeled child maltreatment as negatively predicting our first mediator, self-compassion, which in turn positively predicted internalized shame. We modeled internalized shame as positively predicting scores on our dependent variable, adult depressive symptoms. Participants were 158 adults fluent in English who were community members and college students living in a southwestern American metroplex. The model accounted for 61.8% of the variance in depressive symptoms in adulthood. A significant indirect effect from child maltreatment passed through both our mediators and ended in depressive symptoms in adulthood. We discuss limitations and theoretical and clinical implications, and future directions.

The present study aims to examine which maladaptive and Big Five personality traits, as well as which lower order facets, are related to symptoms specific to PTSD (i.e., intrusions and avoidance). Unique effects were isolated by controlling for nonspecific general depression that occurs in the disorder but is not specific to it. 707 undergraduate students were administered a self-report online survey to assess their personality, trauma history, PTSD and mood symptoms. Additionally, data from 536 9/11 World Trade Center (WTC) responders who have been administered personality, PTSD, and mood surveys as part of a longitudinal study were analyzed. As expected, neuroticism was highly correlated with PTSD, but had fewer associations with PTSD dimensions after controlling for depression. Trust and agreeableness emerged as important, being negatively related to PTSD, while most maladaptive personality domains and facets were positively related to PTSD (perceptual dysregulation had the highest association). Other traits, such as antagonism and openness, were not significantly related to PTSD. There is growing evidence that clinical interventions can change personality traits; the present study provides new personality targets for intervention that are uniquely related to PTSD.

Zn-Mo coatings are very promising environment friendly anticorrosive coatings as replacement materials for cadmium and chromium (VI) based conversion layers. Electrodeposition has become a favorable technique in fabricating coatings due to its low cost, ease of use, and overall experimental control of coating quality. Very little research so far has been done for the electrodeposition of Zn-Mo coatings under alkaline conditions. In this work, Zn and Zn-Mo coatings were electrochemically deposited on stainless steel from an aqueous alkaline citrate solution. An organic compound, vanillin, was added to the electrolyte as a leveling agent for improving interlayer adherence and corrosion resistance of Zn-Mo coatings. Ni-Mo alloys have been known to possess high tensile strength and excellent corrosion protection of steels, and MoTe2 layers have a potential for the application in anticorrosive coatings due to their hydrophobic properties. In this study, MoTe2-Ni-Mo coatings were deposited on stainless steel using both sputtering and electrodeposition methods. These coatings with high corrosion resistance and other desirable properties are in demand in the oil and gas industry since they can protect and thus extend the lifetime of the underlying materials when exposed to aggressive environments. The Zn-Mo and MoTe2-Ni-Mo coatings were evaluated for chemical composition and …

Environmental stress conditions can drastically affect plant growth and productivity. In contrast to soil moisture or salinity that can gradually change over a period of days or weeks, changes in light intensity or temperature can occur very rapidly, sometimes over the course of minutes or seconds. So, in our study we have taken an metabolomics approach to identify the rapid response of plants to light stress. In the first part we have focused on the ultrafast (0-90 sec) metabolic response of local tissues to light stress and in the second part we analyzed the metabolic response associated with rapid systemic signaling (0-12 min). Analysis of the rapid response of Arabidopsis to light stress has revealed 111 metabolites that significantly alter in their level during the first 90 sec of light stress exposure. We further show that the levels of free and total glutathione accumulate rapidly during light stress in Arabidopsis and that the accumulation of total glutathione during light stress is dependent on an increase in nitric oxide (NO) levels. We further suggest that the increase in precursors for glutathione biosynthesis could be linked to alterations in photorespiration, and that phosphoenolpyruvate could represent a major energy and carbon source for …
