Item A comparison of the effects of mobile device display size and orientation, and text segmentation on learning, cognitive load, and user perception in a higher education chemistry course(2015-05) Karam, Angela Marie; Resta, Paul E.; Liu, Min; Hughes, Joan E.; Riegle-Crumb, Catherine; Matthew, EastinThis study aimed to understand the relationship between mobile device screen display size (laptops and smartphones) and text segmentation (continuous text, medium text segments, and small text segments) on learning outcomes, cognitive load, and user perception. This quantitative study occurred during the spring semester of 2015. Seven hundred and seventy-one chemistry students from a higher education university completed one of nine treatments in this 3x3 research design. Data collection took place over four class periods. The study revealed that learning outcomes were not affected by the mobile screen display size or orientation, nor was working memory. However, user perception was affected by the screen display size of the device, and results indicated that participants in the sample felt laptop screens were more acceptable for accessing the digital chemistry text than smartphone screens by a small margin. The study also found that neither learning outcomes, nor working memory was affected by the text segmentation viewed. Though user perception was generally not affected by text segmentation, the study found that for perceived ease of use, participants felt medium text segments were easier to learn from than either continuous or small test segments by a small margin. No interaction affects were found between mobile devices and text segmentation. These findings challenge the findings of some earlier studies that laptops may be better for learning than smartphones because of screen size, landscape orientation is better for learning than portrait orientation in small screen mobile devices, and meaningful text segments may be better for learning than non-meaningful, non-segmented, or overly segmented text. The results of this study suggest that customizing the design to the smartphone screen (as opposed to a one-size-fits-all approach) improves learning from smartphones, making them equal to learning from laptops in terms of learning outcomes and cognitive load, and in some cases, user perspective.Item Ordinary finance(2022-07-08) Yang, Nel; Stewart, Kathleen, 1953-; Handman, Courtney; Campbell, Craig; Seaver, NickIn the present of late capitalism, “finance” describes all manner of economic activity from the moneyed traders of Wall Street to banal activities of household budgeting and accounting. Financial institutions and, more recently, the wide accessibility of financial technologies like apps for banking, investment, commerce, and payment have made financial practice ubiquitous. The process by which financial logics, behaviors, and knowledges proliferate beyond their native realm of “high finance” (of exchanges, traders, and banks) has been called “financialization.” While financialization and its study has richly explained the development of “low finance” in ordinary life, it is less effective in describing activities that contradict narratives of economic rationality and accumulation. Here, I articulate a finance aesthetics to extend the social studies of finance. To do so, I bring together three fields of sociocultural phenomena: the erotic fetish-practice of financial domination (findom), the massive popularity of Taiwanese claw machines, and the industry and disciplinary field of user experience research. These seemingly disparate sociocultural contexts demonstrate the intricate relations between economic, political, technological, and sexual modes of life. In these in-betweens, value transformations (Munn 1986) occur on a plane of aesthetic and sensory experience. Rather than explaining these “non-rational” behaviors, like winning cute garbage or eroticizing monetary loss, the logic of quantities is coopted and repurposed in the exchange and circulation of qualities. The body of this text is organized in three major parts, each frame by a different mythology about contemporary finance (Barthes 1957): that finance capital is fictitious or speculative, that it requires and extracts modes of human attention, and that the finance industry scams the wider public of resources and value. Borrowing from the social studies of finance, conceptually and thematically, this study describes ordinary finance, not as an ordinary infiltrated by the financial, but as the emergence of aesthetic experiences in productive tension with financialization.Item Su voz, su decisión : data-driven system to support day laborers in making informed employment decisions(2016-08) Narya, Shrankhla; Gorman, Carma; Bias, Randolph; Park, Jiwon; Boggess, BethanyWage theft and worksite injury is a significant issue for day workers in Texas and across the nation. In Texas, where a majority of day laborers are undocumented and therefore more vulnerable, the most urgent issue that needs to be addressed is exploitation, which is often compounded by laborers’ lack of access to information about worker rights and employers’ reputations. In 2014 alone, 524 workers were documented to have been killed on their job site in Texas, while many deaths went unreported. And between 2010 and 2014, more than 40,000 Texan workers were victims of wage theft amounting to a total of more than $70 million. Operating in the field of ICT (Information and Communication Technology), I hypothesize that access to both English- and Spanish-language information about worker rights and potential employers’ labor violation-related records can empower workers to make informed employment decisions that will increase their safety and prosperity. At a time when the field of design and advanced digital technologies can skew toward serving the privileged and elite of the society, I am using technology to help members of marginalized/disadvantaged communities use information to improve their economic condition and quality of life: in short, to effect social justice from the bottom up. In my thesis project, Su Voz, Su Decisión, meaning your voice, your decision, I use the methodology of user-centered design to design a mobile app that provides a system of information access for day laborers in Austin. In this report, I will discuss the process of user experience (UX) design that I followed to design the solution, which is a mobile app for Android and iOS, and how I used physical data visualization to represent the data that helped me create the app.
