Show moreBackground: Breast cancer is the most common cancer in the world with approximately 1.7 million new cases diagnosed in 2012. While women with breast cancer are treated with a multitude of different therapies, these treatments can lead to long-term effects that impact quality of life (i.e. fatigue, pain, lymphedema, anxiety, depression, osteoporosis). With more people looking into complementary and alternative medicine (CAM), research on yoga�s effect on quality of life in breast cancer survivors is vital. Methods: This literature synthesis used PsychINFO, MEDLINE, and CINAHL explore current research on yoga's effects on quality of life in breast cancer survivors. Search terms included: breast cancer, survivor, quality of life, lifestyle, wellbeing, clinical trial, and controlled trial. Literature was excluded if it included men, women under cancer treatment and if yoga was included in a mindfulness intervention. Results: Eleven articles met the inclusion criteria. Yoga was shown to have a positive impact on fatigue, pain, anxiety, depression, and breast cancer survivors' quality of life. A majority of the studies measured quality of life using the FACT-B and FACT-G scale. Others used similar measurement tools and qualitative journal entries. Specific studies indicated improvements in aromatase-inhibitor associated arthralgia, diurnal salivary cortisol levels, and menopausal symptoms. Conclusions: Yoga appears to be beneficial in improving breast cancer survivor's quality of life. More research is needed. However, nurses can use this information to educate clients about the benefit of yoga in survivorship. This research may promote further utilization of CAM in improving quality of life.

Show moreMalaria is one of the most devastating infectious diseases causing 1-3 million fatalities a year. The majority of these cases occur amongst children in developing countries. Malarial strains in these areas are exhibiting increasing resistance to canonical treatments proving the importance of new drug targets for anti-malarials. Identification of new drug targets is dependent upon a better understanding of the molecular biology of the parasitic agent of malaria, Plasmodium. The regulation of Plasmodium's complex life cycle is still not well understood. Elucidation of signaling pathways involved in Plasmodium cell cycle regulation will provide insights into how the parasite thrives in human cells. A subset of kinases, referred to as cyclin-dependent kinases (CDKs), are crucial regulators of eukaryotic cell cycle progression. In silico studies show high homology between mammalian CDK's and a group of CDK-like Plasmodium kinases including PfPK5 (Plasmodium falciparum protein kinase 5). Plasmodium homologues to CDK regulators, cyclins, have also been identified. Understanding the role of PfPK5 in cell cycle regulation would require analysis of subcellular localization and cell cycle-dependent expression. Immunofluorescence assays demonstrate that PfPK5 is localized in the nucleus. PfPK5's expression profile, as determined by western blotting, shows highest expression in the schizont stage, the stage when the atypical multiple nucleated form of the parasite is observed. Possible PfPK5 interacting partners were detected by performing an anti-PfPK5 immunoprecipitation assay. Additionally, a hemagglutinin (HA)-tagged PfPK5 construct was made to increase the sensitivity of immunoprecipitation assay and identification of PfPK5 interacting partners. The characterization of PfPK5 and its interacting partners may prove useful in identification of novel drug targets in the future.

Show moreVirtual Worlds have become an attractive platform for work, play, and learning. Businesses, including the public sector and academia, are increasingly investing their time, money, and attention to understanding the value of virtual worlds as a productivity tool. For example, educators are leading the way with research in Second Life, one of the more popular virtual worlds, as a potentially powerful medium for creating and delivering instruction. Still, little is empirically known about the value of virtual worlds as viable learning platforms. This study examined the instructional potential of Second Life for creating engaging activities, and to investigate the relationship between Second Life and learning in educational settings. It was hypothesized that a positive relationship exists between a learner's level of engagement and achievement. Achievement was assessed as a learner's level of recognition and recall of factual content. It was also hypothesized that a positive relationship exists between a learner's level of engagement and their performance. Performance was assessed as a learner's level of participation, initiative and effort. Additionally, exploratory research was conducted to examine the factors that contributed to both performance and engagement. Lastly, the relationship between other demographic factors of age, Second Life skill level, and ethnicity, with engagement was explored. This research used an empirically tested unit of web-based instructional framework known as a WebQuest. A 3D version, named VWQuest, was created in Second Life. One hundred volunteers completed participation. Using role play, participants participated in a quest for information. While exploring, participants were asked to take photos as evidence of their experiences. Upon completion, they took a knowledge check multiple-choice quiz, and a survey which measured their perceived level of engagement during the activity. iii Regression analysis indicated no positive correlation between a participant's level of engagement and his or her achievement. However, a positive correlation was found between participants' level of engagement and their performance. Second Life skill level was significantly correlated to performance, and engagement was found to be a mediator between skill level and performance. Most significantly and unexpectedly, participants' performance varied so greatly, the performance rubric was revised four times before it comprehensively captured the diverse range of performances. This evidence suggests that open-ended and creative opportunities to perform yield levels of creativity, engagement, and innovation within immersive platforms, unexpected and far beyond that of traditional instructional settings. Investigating flow dimensions, engagement elements of user control and loss of time were found to be the most significant contributors to performance, and accounted for the greatest amount of variance in explaining performance. Confirmatory factor analysis showed that the flow factors of defined goals and feedback loaded the highest, suggesting a strong relationship between the two factors. Demographic analysis revealed no significant mean difference between gender and engagement, or between age and engagement. The majority of participants were between 40 and 50 and was instructors or educators, not students. For those interested in understanding appropriate and effective instruction in complex, immersive environments, this study brings together new important implications for all of them. Instructional designers may benefit from these findings in their creation of instructional content; instructors may benefit in their curriculum design and teaching methods; and researchers may understand specific facets with instructional potential – engagement factors, technologies, and instructional frameworks – worthy of further investigation.

Show moreGiven the growing population of aging adults, there is a need for research examining factors that enhance quality of life for older adults (QoL; Colby (&) Ortman, 2014). Changes in health, relationships, support systems, and social identity are inevitable throughout the lifespan. Therefore, research focused on lessening the negative effects of changes due to aging while also improving QoL is warranted. As such, the aim of the current research study was to examine the extent to which subjective age (SA; how old or young an individual feels), playfulness (PF; (")the ability to frame or reframe everyday situations to experience them as entertaining, intellectually stimulating, and/or personally interesting(") [Proyer, 2015, p. 93-94]), and depression (an emotional state ranging from mild discouragement to feelings of extreme despair [CDC, 2017; Corsini, 2002]) predict QoL ((")a person's sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important to him or her(") [Ferrans, 1985, p. 15]) among adults over the age of 55. Using convenience sampling with eligibility requirements, adults (N = 1,315) 55 and older and who spoke and read English were surveyed both face-to-face (F2F) and online (e.g., Amazon Mechanical Turk and a senior educational program). Standard multiple regression was utilized, and results identified a statistically significant model with the variable of depression predicting the largest unique contribution to the model, while PF predicted a small, statistically significant contribution. Subjective age did not statistically contribute to the prediction. Implications from the findings that relate to counselors, counselor educators, and researchers are provided. In addition, the findings provide guidance and a new perspective on variables associated with QoL and aging adults.

Show moreThe aim of the present study is to investigate the extent to which life partners understand the emotional impact stuttering has on their loved one who stutters. This was accomplished by administering the Speech Situation Checklist - Emotional Reaction (SSC-ER), a subtest of the Behavior Assessment Battery (BAB; Vanryckeghem (&) Brutten, 2018) via Qualtrics, an online survey software, to the participants who stutter and a modified version of the SSC-ER to their life partner. No significant differences and a positive correlation were observed between groups (people who stutter (PWS) and their life partner (LP) as it relates to total score on the SSC-ER. Gender, age, and duration of relationship, overall, were not confounding variables that affected the total score. Internal reliability was high across both the SSC-ER and its modified version. All items on the test correlated significantly with the total score with the exception of items 8 and 13 for PWS and items 6, 13, and 36 for LPs. Between-group item analysis revealed that the majority of test items did not differ significantly with the exception of six items: 3, 4, 13, 19, 26, and 27. The aforementioned items follow the construct pertaining to fixed sounds and/or words. The findings in this investigation provide evidence that LPs have a general understanding of the anxiety levels their partner who stutters experiences as it relates to communication situations.

Show moreEvolution on Earth is widely considered to be an effectively endless process. Though this phenomenon of open-ended evolution (OEE) has been a topic of interest in the artificial life communitysince its beginnings, the field still lacks an empirically validated theory of what exactly is necessary to reproduce the phenomenon in general (including in domains quite unlike Earth). Thisdissertation (1) enumerates a set of conditions hypothesized to be necessary for OEE in addition to (2) introducing an artificial life world called Chromaria that incorporates each of the hypothesizednecessary conditions. It then (3) describes a set of experiments with Chromaria designed to empirically validate the hypothesized necessary conditions. Thus, this dissertation describes the firstscientific endeavor to systematically test an OEE framework in an alife world and thereby make progress towards solving an open question not just for evolutionary computation and artificial life,but for science in general.

Show moreThe behavior of materials as they are subjected to combined thermal and mechanical fatigue loads is an area of research that carries great significance in a number of engineering applications. Power generation, petrochemical, and aerospace industries operate machinery with expensive components that undergo repeated applications of force while simultaneously being exposed to variable temperature working fluids. A case of considerable importance is found in steam turbines, which subject blades to cyclic loads from rotation as well as the passing of heated gases. The complex strain and temperature histories from this type of operation, combined with the geometric profile of the blades, make accurate prediction of service life for such components challenging. Development of a deterministic life prediction model backed by physical data would allow design and operation of turbines with higher efficiency and greater regard for reliability. The majority of thermomechanical fatigue (TMF) life prediction modeling research attempts to correlate basic material property data with simplistic strain and thermal histories. With the exception of very limited cases, these types of efforts have been insufficient and imprecise in their capabilities. Early researchers did not account for the multiple damage mechanisms that operate and interact within a material during TMF loads, and did not adequately address the extent of the relationship between smooth and notched parts. More recent research that adequately recognizes the multivariate nature of TMF develops models that handle life reduction through summation of constitutive damage terms. It is feasible that a modification to the damage-based approach can sufficiently include cases that involve complex geometry. The focus of this research is to construct an experimentally-backed extension of the damage-based approach that improves handling of geometric discontinuities. Smooth and notched specimens of Type 304 stainless steel were subjected to several types of idealized fatigue conditions to assemble a clear picture of the types of damage occurring in a steam turbine and similarly-loaded mechanical systems. These results were compared with a number of idealized TMF experiments, and supplemented by numerical simulation and microscopic observation. A non-uniform damage-summation constitutive model was developed primarily based on physical observations. An additional simplistic model was developed based on phenomenological effect. Findings from this study will be applicable to life prediction efforts in other similar material and load cases.

Sixcollege presidents participated in one-on-one semi structured interviews.The researcher incorporated Clark's Work-family border theory as the frameworkfor this study, which recognized that a working individual largely functions in twoseparate domains: work and family. The presidents' experiences were examined withinthis construct and addressed the research question that guided the study: How do malecollege presidents balance their work and life domains?This study represents a significant addition to the scholarly literature concerningwork-life balance experienced by male college presidents as little scholarship exists inthis area. The results led to recommendations and implications for college Boards ofTrustees, professional development associations, spouses, and partners.

This study presents a fourfold typology of respondents: (1) pro-choice, but not religious, (2) pro-choice and religious, (3) pro-life, but not religious, and (4) pro-life and religious. This study looks for characteristics of respondents in these categories. As previous research was examined on the relationship between religion and abortion attitudes, the question on what social characteristics make up the four categories of pro-choice and pro-life respondents was examined. Findings show that social characteristics of respondents vary across categories of subjective religiosity and attitudes toward legal abortion typology. Recommendations are made for future research to utilize this data to continue exploring the relationship between social attitudes towards abortion alongside a person's religiosity.

Show moreThis dissertation investigates the effect of education on the chances and age of marriage during the transition from adolescence into young adulthood among Kenyan women age 15-22. Women who receive more education are more likely to delay marriage. The literature suggests that occupation and age at sexual debut are also significantly associated with age of marriage. This study considers how these and other factors may possibly affect the life course of women in Kenya over a period of time and increases our understanding of marriage predictors. Data comes from the 2003 and 2008 Kenya Demographic and Health Surveys. Binary logistic and OLS regression models are used to analyze and compare the data. The results imply that while education has a statistically significant and strong positive effect on a woman's marital status as well as age of marriage, the effect of education on age of marriage has not changed since the introduction of Kenya's free primary education program.

Show moreThe purpose of this study was to examine the relationships between stigma, quality of life (QoL), and relationships satisfaction for prostate cancer (PCa) survivors and their intimate and/or romantic partners. The investigator tested a theoretical model that stigma (as measured by the Social Impact Scale [SIS; Fife (&) Wright, 2000]) influenced QoL (as measured by the Functional Assessment of Cancer Therapy (-) Prostate [FACT-P; Esper et al., 1997] and the Functional Assessment of Cancer Therapy (-) General Population [FACT-GP; Cella et al., 1993]) and relationship satisfaction (as measured by the Couples Satisfaction Index [CSI; Funk (&) Rogge, 2007]) for both PCa survivors and their partners (N = 72 couples). The investigator hypothesized that stigma would have a negative influence on both QoL and relationship satisfaction. Further, exploratory research questions pertained to the influence of race on stigma, QoL, and relationship satisfaction, as well as examining difference in experiences of stigma based on demographic variables (e.g., age and income).The results of the structural equation model analyses identified that stigma negatively influenced QoL (R2 = .84, p (<) .05) and relationship satisfaction (R2 = .19, p (<) .05) for both PCa survivors and their partners. Race did not have statistically significant (p (>) .05) relationships with stigma, QoL, or relationship satisfaction and stigma was not found to be statistically different (p (>) .05) based on demographic variables. Implications of the results of the study include (a) practical implications for PCa survivors and their partners; (b) strategies for effective individual, group, and couples-based counseling; (c) need for counselor educators to prepare counselors to work with medically ill populations and cancer survivors; (d) PCa stigma instrument development; and (e) the necessity to examine research with couples in a dyadic fashion.

Show moreAssessment Centers (ACs) are a fantastic method to measure behavioral indicators of job performance in multiple diverse scenarios. Based upon a thorough job analysis, ACs have traditionally demonstrated very strong content and criterion-related validity. However, researchers have been puzzled for over three decades with the lack of evidence concerning construct validity. ACs are designed to measure critical job dimensions throughout multiple situational exercises. However, research has consistently revealed that different behavioral ratings within these scenarios are more strongly related to one another (exercise effects) than the same dimension rating across scenarios (dimension effects). That is, results from ACs suggest that we are unsure of what these behavioral measures represent. Over the last three decades, researchers have sought to illuminate why same dimension ratings are inconsistent across scenarios. However, these investigations have been limited to changes influencing the source of the ratings (e.g., assessors, trained raters). No approach has been taken to change the structure of the AC. This study breaks with tradition and introduces a structurally different AC: A Day-In-The Life AC (DITLAC). A DITLAC structure is designed to mimic that of a normal day on the job. In the present study, the construct validity between a DITLAC and a traditionally structured AC is compared with the argument that the DITLAC will demonstrate stronger construct validity evidence. In several cases, this was found to be true.

Show moreThis dissertation aims to investigate the sustainability impacts of alternative vehicle technologies and develop comprehensive sustainability assessment frameworks to analyze potential impacts of these vehicles in the U.S. In order to assess sustainability impact of vehicle alternatives, life-cycle based models has been extensively used in the literature. Although life cycle-based models are often used for environmental impacts of alternative vehicles, analysis of social and economic impacts of these vehicles has gained a tremendous interest. In this regard, there is a growing interest among the international platform and academia to use the Life Cycle Sustainability Assessment framework to have more informed sustainable products, material and technology choices by considering the environmental, as well as social and economic impacts. The Life Cycle Sustainability Assessment framework is still under development and there is an ongoing research to advance it for future applications. In this dissertation, current and future needs of sustainability assessment frameworks and the U.S. transportation are identified and addressed. The major research gaps are identified as follows: (1) there has been small emphasis on effects of spatial and temporal variations on the sustainability impacts of alternative vehicle technologies, (2) no national research efforts as of now have been directed specifically toward understanding the fundamental relationship between the adoption of electric vehicles and water demand, (3) there has been a lack of understanding the dynamic complexity of transportation sustainability, encompassing feedback mechanisms, and interdependencies, for the environmental, social, and economic impacts of alternative vehicles, and (4) there is no emphasis on addressing uncertainties inherent to the U.S. transportation and its complex relationships with the environment, society, and economy.The environmental, economic, and social impacts of alternative vehicles are highly critical for truly assessing and understanding the long-term sustainability of vehicles and propose economically viable, socially acceptable, and environmentally-friendly transportation solutions for U.S. passenger transportation. This dissertation provides a more comprehensive sustainability assessment framework by realizing following objectives: (1) inclusion of spatial and temporal variations when quantifying carbon, energy, and water footprints of alternative vehicle technologies, (2) quantifying environmental, social, and economic impacts of alternative vehicle technologies, (3) capturing the dynamic relations among the parameters of U.S. transportation system, environment, society, and the economy, (4) dealing with uncertainties inherent to the U.S. transportation sector considering the complexity of the system and dynamic relationships. The results of this dissertation reveal that the results with consideration of uncertainties, temporal and spatial variations, and dynamic complex relationships among the system variables can be significantly different than those of without consideration of those. Therefore, when developing policies the robustness of proposed scenarios should be valuated with consideration of uncertainties, temporal and spatial variations as well as the dynamic feedback mechanisms. The outcomes of this study can pave the way for advancement in the state-of-the-art and state-of-the-practice in the sustainability research by presenting novel approaches to deal with uncertainties and complex systems.

Show moreThis purpose of the study is to examine the difference in the health-related quality of life (HRQOL) between individuals who suffer from physician-diagnosed arthritis compared with individuals who do not suffer from physician-diagnosed arthritis in a population of university students, faculty, and staff. The study sampled from a population of students, faculty, and staff at the University of Central Florida. Through the implantation of a cross-sectional ecological design, differences between the two groups were measured with a survey that measures health-related quality of life, such as the 36-Item Short Form Health Survey (SF-36). The SF-36 questionnaire was distributed to subjects through a campus-wide email system and was administered through Qualtrics, an online survey program. Literature suggests lower SF-36 scores for individuals suffering from arthritis, but is lacking in investigating the effect of arthritis on college-aged students, particularly within the 18-24 age group. The study aims to close this gap in the literature. SPSS software was used to analyze results through tests of association, like ANOVA, which measured differences in the SF-36 scores of subjects with physician-diagnosed arthritis and subjects without physician-diagnosed arthritis. Results showed a significant difference in the HR-QOL scores between individuals with arthritis and individuals without arthritis, as well as age, gender, ethnicity, and the presence of joint pain.
