The Struggle For 'Appropriateness'-New Sources Of (Techno-) Stress, Stefan Schellhammer, Russell Haines, Stefan Klein

Information Technology & Decision Sciences Faculty Publications

Information and communication technologies are employed in every aspect of contemporary life. Facilitated by ICT, many innovations in the organization of work have taken hold. The effects of these developments on the quality of life are disputed. By referring to the phenomenon of ‘technostress,’ scholars’ caution against potentially harmful effects of ICT on workers’ health. This relatively new line of research roots the sources of stress for the individual in features of ICT. The present paper is motivated by the observation that ICT is also rooted in social relations. The way it is used is heavily influenced by social norms …

Microfinance: A Tool For Diminishing Food Insecurity, Ashley Armstrong

Miller Center Fellowship

Paraguay is one of the poorest countries in South America. Most Paraguayans fail to get the nutritional value they need with 25.5% of the adult population living under the minimum dietary consumption level (WHO, 2012). Food security in Paraguay is not primarily affected by food availability but rather by food access and food use, which are heavily influenced by poverty, education, culture, land tenure, and domestic agricultural production. Microfinance – the business of supplying financial services to poor people who are frequently excluded from the formal banking sector – is a viable vehicle for diminishing food insecurity in Paraguay by …

Contesting Neoliberalism Through Critical Pedagogy, Intersectional Reflexivity, And Personal Narrative: Queer Tales Of Academia, Richard G. Jones, Bernadette Marie Calafell

Critical Race and Ethnic Studies Faculty Scholarship

In this article, we use personal narrative to explore allies and alliance building between marginalized people working in and through higher education, with an eye toward interrogating the ways in which ideologies of neoliberalism work to maintain hierarchy through the legitimation of othering. Inspired by Conquergood (1985), who calls scholars to engage in intimate conversation rather than distanced observation, we offer our embodied experiences as a way to use the personal to reflect on the cultural, social, and political. Our narratives often recount being out of place, moments of incongruence, or our marked otherness. Through the sharing of these …

Middle School Special Education Reading Teachers' Experiences Utilizing Study Island Technology To Enhance Male Students' Literacy: An Exploratory Case Study, Roddran Grimes

All-Inclusive List of Electronic Theses and Dissertations

This mixed methods study examined the experiences that four middle school special education teachers had implementing an online education program called Study Island in their reading classes. The teachers wanted to increase their students' reading decoding and comprehension skills and also wanted to prepare their students for their state's standardized test. Many male students today are underachieving academically and lack motivation to excel in their studies. Because boys comprise the majority gender in most resource classes (i.e., only special education students), this study focused on the male population in order to determine whether an online education program with a game …

The Elephant In The Room: Gonduct, Groups, And Lawrence V. Texas, Elliot Wong

UC Law Constitutional Quarterly

In its landmark 2003 decision of Lawrence v. Texas, the United States Supreme Court articulated that a ban on homosexual sexual conduct had a meaningful and negative effect on the lives of homosexuals. So significant was the effect on homosexuals that ultimately the Court declared the ban on the underlying conduct unconstitutional.

Following Lawrence, courts and commentators have questioned the true effects of the Court's broad language. The Court's opinion relies heavily on the adverse practical effect the ban had on homosexual persons. But what exactly did Texas' unconstitutional law really target? Was it homosexuals as a group, was it …

The Role Of Bcl-2 Family In Clinical Response Of Chronic Lymphocytic Leukemia, Sayer Rashed Alharbi

ETD Archive

The anti-apoptotic Bcl-2 proteins regulate lymphocyte survival and are over-expressed in lymphoid malignancies, including chronic lymphocytic leukemia (CLL). The small molecule inhibitor ABT-737 binds with high affinity to Bcl-2, Bcl-xl, and Bcl-w but with low affinity to Mcl-1, Bfl-1, and Bcl-b. The active analog of ABT-737, navitoclax, has shown a high therapeutic index in lymphoid malignancies developing a predictive marker for it would be clinically valuable for patient selection or choice of drug combinations. We compared expression of anti-apoptotic Bcl-2 genes that are known to be targeted by ABT-737. Our findings reveal that the relative ratio of Mcl-1 and Bfl-1 …

Study Of The L13a Residues Required For Ribosomal Function, Priyanka Das

ETD Archive

Ribosome biogenesis, a fundamental process, occurs in the nucleolus. It involves incorporation and association of ribosomal proteins (r-proteins) in the ribosomal subunit. Despite its obligatory and critical role in cellular function, the explicit mechanism of incorporation of different r-proteins into the pre-ribosome is not well understood. Using mammalian cell and r-protein L13a as our model, this study addresses the function and mechanism of r-protein incorporation during ribosome maturation. Published results from our laboratory showed the requirement of the release of L13a from the 60S ribosome to silence a cohort of inflammatory proteins directly at the level of translation thus showing …

Same-Race Regulatory Resource Depletion;Obstacles Of Black High-Achievers, Shondale Deloach

ETD Archive

Researchers have long been interested in the academic underachievement and disengagement of many African American students. Fordham and Ogbu (1986) offered the acting White phenomenon as one way to understand the problem. Fordham (1996) found that, in order to avoid being accused of acting White, some Black high achievers limit their academic abilities, particularly around Black low achieving students. Black high achievers can also encounter psychological costs as a result of limiting their academic prowess. There is some evidence, according to regulatory resource depletion theory, that altering one's normal thoughts, actions, or feelings in order to serve present circumstances, as …

Modification Of Behavior Of Elastin-Like Polypeptides By Changing Molecular Architecture, Ali Ghoorchian

ETD Archive

Elastin-like polypeptides (ELP) are environmentally responsive polymers that exhibit phase separation in response to external stimuli such as temperature, pH, light, and ionic strength. It has been shown that the sequence of the pentapeptide, its length, and the solution concentration are very important in the transition of the molecules from soluble to insoluble, but there has not been any detailed study of the effect of molecular architecture on the behavior of ELPs.In this study we designed, synthesized and characterized ELPs with different architectures and chemical identities to probe the effect of molecular design on the microscopic and macroscopic behavior of …

A Survey Of The Structural Determinants Of Local Emergency Planning Committee Compliance And Proactivity;Towards An Applied Theory Of Precaution In Emergency Management, Erica M. Matheny

ETD Archive

Millions of factories, chemical facilities, and highways store or convey extremely hazardous substances (EHS) in proximity to populated residential and commercial areas. The proliferation of hazardous chemicals in manufacturing has led to thousands of facilities that store and utilize them throughout the United States. There is inherent risk to neighborhoods and populated areas located near facilities that use and store hazardous chemicals. Local Emergency Planning Committees (LEPCs) were created in 1987 as stakeholder based, primarily volunteer organizations that address hazardous chemical accident mitigation. In addition, LEPCs were mandated with the intent of engaging communities in the debate about hazardous materials. …

Rnase L Manipulates Macrophages In Innate Immunity And Tumor Growth, Xin Yi

ETD Archive

RNase L is one of the key enzymes in the 2-5A system of interferon (IFN) action against viral infection and cellular proliferation. Tissue distribution analysis has revealed that RNase L is highly expressed in the spleen, thymus, lung, testis, intestine and most of immune cells such as T, B cells and macrophages. However, the physiological role of RNase L in the immune system is largely unknown. My thesis thus focused on studying the possible physiological role of RNase L in macrophages. By using bone marrow-derived macrophages (BMMs) from RNase L+/+and -/- mice, we demonstrated that RNase L is involved in …

Purification And Characterization Of Blood Aspirin Hydrolases, Gang Zhou

ETD Archive

Aspirin prophylaxis suppresses major adverse cardiovascular events, but its turnover in blood is rapid, which limits its inhibitory effects on platelet cyclooxygenase and thrombosis. Inter-individual variability of platelet responses to aspirin clinically presents as treatment failure, and this increasing clinical phenomenon is frequently named aspirin "resistance". However, the molecular mechanisms behind this are unclear. Blood aspirin hydrolases are believed to control aspirin survival in vivo, but the identity of the circulating enzyme(s) that hydrolyzes aspirin remains unknown. In this thesis, blood aspirin hydrolases were identified and characterized. The relationship between blood aspirin hydrolases and aspirin efficacy was investigated. RP-HPLC analysis …

Myocardial T1 Mapping Techniques For Quantification Of Myocardial Fibrosis, Xiaopeng Zhou

ETD Archive

Identifying and quantifying diffuse myocardial fibrosis is important to provide insights into the relationship between myocardial fibrosis, diastolic and systolic dysfunction, as well as clinical outcomes. T1 mapping is a promising technique for noninvasively identifying diffuse myocardial fibrosis in heart failure. A quantitative T1 map provides sensitivity to the full range of T1 values and is advantageous over the traditional T1-weighted imaging by reducing the reliance on visual interpretation of the signal intensity in the myocardium. However, in-vivo myocardial T1 quantification is challenging because of cardiac and respiratory motion. During the past few years, a variety of T1 mapping techniques, …

Effects Of Magnesium Sulfate, Digestate And Other Inorganic Nutrients On The Phototrophic Growth Of The Green Microalga Scenedesmus Dimorphus, Jacob R. Schwenk

ETD Archive

The individual components of the growth media, notably magnesium, have a profound impact on the growth and lipid production of the green microalgae, Scenedesmus dimorphus. The goal of this work was to investigate these effects and explain the causes via multiple experiments. It is important to understand the aspects of algal growth because they have a significant impact on the commercial viability of microalgal lipids as a potential feedstock for biofuel production. Digestate, derived from bovine waste and a potential cost effective nutrient replacement for conventional media types, was found to maximize growth and lipid concentration in S. dimorphus at …

Effect Of Glucose Supplementation On Nighttime Biomass Loss And Productivity Of Microalgae Chlorella, Dhruvesh Shah

ETD Archive

Microalgae have been proven to be a promising source for the production of biofuel. It has higher oil yield than any other food crop. Oil yield from microalgae is 7 to 13 times higher than the best food crop. There are several issues to be addressed for economic production of biofuel from microalgae. One such issue is cultivation of microalgae. Algae can be cultivated photoautotrophically or heterotrophically. Algae grown photoautotrophically lose up to 35 of the biomass during nighttime. Heterotrophic cultivation of microalgae has been proven to be resulting in faster microalgae production compared to photoautotrophic growth, but requires use …

Characterization Of Elastic-Like Polypeptide Micelles Using Capillary Viscometry, Sumit H. Kambow

ETD Archive

Elastin-like polypeptides (ELPs) are a part of the family of responsive polymers. These polymers can be made to respond to a wide variety of stimuli, including temperature, pH, salt, concentration, light, and solvent. Elastin-like polypeptides are soluble in water at low temperatures but they become hydrophobic and insoluble above their transition temperature. Elastin-like polypeptides, (GVGVP)40-foldon and (GVGVP)60-foldon, were expressed in bacterial system. These ELPs above their transition temperature, Tt, at low salt (< 45mM) and high pH (> pH 10) assemble into micelles where the hydrophobic tails phase separate in the interior of the micelle as an immiscible coacervate phase. The oligomerization domain termed as …

The Effects Of Group Essence Survival On Group Morale, Mark R. Wojda

ETD Archive

Morale has been defined as, "the capacity of a group of people to pull together persistently and consistently in pursuit of a common purpose" (Leighton, 1949, p. 78). What is missing in our understanding of morale is knowing precisely what generates, increases, and decreases morale. One purpose of the current project is to explore these aspects of morale. Specifically, one factor that may boost or drive morale is the survival of the group's identity, or common purpose. The "essence" of a group includes their values, ideals, and identity that may live on even after current members of the group no …
