Cost-Sensitive Learning-Based Methods For Imbalanced Classification Problems With Applications, Talayeh Razzaghi
Cost-Sensitive Learning-Based Methods For Imbalanced Classification Problems With Applications, Talayeh Razzaghi
Electronic Theses and Dissertations
Analysis and predictive modeling of massive datasets is an extremely significant problem that arises in many practical applications. The task of predictive modeling becomes even more challenging when data are imperfect or uncertain. The real data are frequently affected by outliers, uncertain labels, and uneven distribution of classes (imbalanced data). Such uncertainties create bias and make predictive modeling an even more difficult task. In the present work, we introduce a cost-sensitive learning method (CSL) to deal with the classification of imperfect data. Typically, most traditional approaches for classification demonstrate poor performance in an environment with imperfect data. We propose the …

Exploring Stereotype Threat In The Workplace With Sexual Minorities, Elizabeth Sanz
Exploring Stereotype Threat In The Workplace With Sexual Minorities, Elizabeth Sanz
Electronic Theses and Dissertations
Sexual minorities are the target of numerous negative stereotypes in the United States, and are sometimes perceived as deviant and devalued as compared to heterosexuals. Stereotype threat, the anxiety of confirming a negative stereotype about oneself or one's group, has been linked to perceived stress; and stress has been linked to low job satisfaction. Sexual minorities provide a unique test of stereotype threat theory because they may choose to conceal their minority status at work. Thus, this study also examines whether the visibility of the stigma is a necessary precursor to the experience of stereotype threat. Given the uniqueness of …

Decentralized Power Management And Transient Control In Hybrid Fuel Cell Ultra-Capacitor System, Seyed Omid Madani
Electronic Theses and Dissertations
Solid Oxide Fuel Cells (SOFCs) are considered suitable for alternative energy solutions due to advantages such as high efficiency, fuel flexibility, tolerance to impurities, and potential for combined cycle operations. One of the main operating constraints of SOFCs is fuel starvation, which can occur under fluctuating power demands. It leads to voltage loss and detrimental effects on cell integrity and longevity. In addition, reformer based SOFCs require sufficient steam for fuel reforming to avoid carbon deposition and catalyst degradation. Steam to carbon ratio (STCR) is an index indicating availability of the steam in the reformer. This work takes a holistic …

Home Nowhere: Assorted Prose, Rebecca Fortes
Home Nowhere: Assorted Prose, Rebecca Fortes
HIM 1990-2015
Oftentimes, the children of immigrants find themselves straddling two worlds. As Americanized minorities, we navigate torn psychological landscapes in which uneasy dichotomies are formed: living up to our parents' expectations, or fulfilling our own; embracing tradition, or birthing a new culture; admiring the lives of our family, but wanting different for ourselves. These tough decisions are further compounded by identifiers such as age, race, and gender. My creative thesis, a collection of fiction and nonfiction, examines these issues through three central characters. In fiction, they are the Latina sisters Mel and Nena; in nonfiction, it is myself. Through these stories, …
Imago Dei: Stories, Benjamin Langevin
Imago Dei: Stories, Benjamin Langevin
HIM 1990-2015
Translated from Latin, Imago Dei means the image of God. In the very beginning of the Torah, the writer says that God created humanity in Their own image. According to the text, woven in the fabric of who we are is God. In a post-secular society, the concept of God brings a lot of weight and baggage. Which God are we talking about? Can God be talked about it? Is God or thinking about God even relevant anymore? Hasn't science taken care of it? What good can discussions on faith bring us? These are the questions explored in Imago Dei: …
Design And Implementation Plan For The "I Am Potential" Financial Literacy Education Program, Tureka Louis
Design And Implementation Plan For The "I Am Potential" Financial Literacy Education Program, Tureka Louis
Electronic Theses and Dissertations
This Financial Literacy Program Model is a proposed solution to the problem of financial illiteracy among the working poor. Over 80 percent of adults in America are not financially literate, yet more than half believe themselves to be (OECD, 2005). No community is more adversely affected by this fallacy than the working poor. Earning income, yet living below the poverty line, this group is as deceived as any other by the misconception that increased income is their sole remedy rather than a small part of the complex equation greatly influenced by financial literacy. Drawing upon a review of related literature, …

Hope And Low Level Literacy Of Haitians In Petit-Goave: Implications For Hope Theory And Adult Literacy Education, Donita Grissom
Electronic Theses and Dissertations
This cross-sectional study extended Snyder's Hope Theory (1991) by analyzing the difference in trait hope levels, pathway thinking, and agency thinking of pre-literate (no prior access to literacy) and non-literate (access to literacy, but little or no prior literacy education) Haitian adults. The data were derived from archival records of 135 students enrolled in Haitian-Kreyol adult literacy classes in Petit-Goave, Haiti. Mann-Whitney U results indicated that there were no significant differences in trait hope, pathway thinking, or agency thinking between the pre-literate and non-literate Haitian adults. Both groups reported average trait hope, average pathway thinking, and low agency thinking. Potential …
