Towards An Economic Geography Of Fintech, Karen P. Y. Lai, Michael Samers

Geography Faculty Publications

In this paper, we identify the ways in which the existing literature has examined financial technology (FinTech). Using the frame of the ‘FinTech Cube’, we examine how FinTech unfolds through the intersections of key actors, technologies and institutions. We demonstrate the relevance of FinTech for two areas of geographical enquiry: i) the reshaping of global production and financial networks, and ii) financial inclusion and poverty reduction in poorer countries. In doing so, we accord particular attention to the significance of FinTech for theoretical and empirical research in economic geography.

Education Through Time: Representations Of U.S. Education On Time Magazine Covers, Dani Kachorsky, Stephanie F. Reid, Kathryn Chapman

Educational Leadership Studies Faculty Publications

This study examined how TIME Magazine has visually represented and communicated ideas about education from TIME Magazine’s inception in 1923 through 2019. Drawing on theories of visual culture and social semiotic approaches to multimodality, the researchers conducted a qualitative multimodal content analysis of 115 covers that featured content related to education and schooling. The findings included (a) names and places are used to suggest authority, power, or relevance in education circles; (b) learning and schooling are presented as having not changed over time; (c) overgeneralized and metonymic representations can stand for broad categories of education stakeholders; (d) schools are presented …

The Full Impact Of The Affordable Care Act On Political Participation, Charles J. Courtemanche, James Marton, Aaron Yelowitz

Economics Faculty Publications

This article examines the impact of both the Medicaid expansion and the private insurance-related components of the Affordable Care Act (ACA) on voter turnout and registration. We employ a difference-in-difference-in-differences identification strategy exploiting variation over time, state Medicaid expansion status, and within-state local area pre-ACA uninsured rates. Using data between 2006 and 2016 from the November Current Population Survey and the Census Bureau's Small Area Health Insurance Estimates, our results suggest little effect of the ACA on voter turnout or registration.

We Are Right, They Are Wrong: The Antagonistic Relationship Between Populism And Discourses Of (Un)Truthfulness, Michael Hameleers

disClosure: A Journal of Social Theory

Populism maintains a specific relationship with discourses of (un)truthfulness. Yet, although a growing body of research has explored the nature and effects of populist rhetoric, populism’s cultivation of reality and dishonesty has been under-theorized. In this paper, we explore three relationships between populism and (un)truthfulness: (1) the cultivation of a conspiracy theory in populist discourse; (2) populism’s denial or discrediting of expert knowledge or empirical information, and the legitimacy of journalism and mainstream sources of knowledge and (3) populist constructions of alternative truths that resonate with common sense and the experiences of the ordinary people. We further explore the effects …

Nationalpopulism, Right And Left: The Social-National Synthesis Today, Daniel Rueda

disClosure: A Journal of Social Theory

For most of the postwar period the idea of merging socialist (or popular) and nationalist elements was marginal in Europe. But in the last two decades we have been witnessing a new form of social-national synthesis: nationalpopulism. This article examines this resurgence by comparing right-wing nationalpopulism and left-wing nationalpopulism. In order to do so, it focuses on four European countries: France, Italy, Greece and Spain. While there are both policy and discursive similarities between these two forms of nationalpopulism, this article argues that they are fundamentally different and belong to antagonistic ideological factions.

Adorno’S Critique Of The New Right-Wing Extremism: How (Not) To Face The Past, Present, And Future, Harry F. Dahms

disClosure: A Journal of Social Theory

This paper serves three purposes relating to a lecture Adorno gave in 1967 on “the new right-wing extremism” that was on the rise then in West Germany; in 2019, the lecture was published in print for the first time in German, to wide acclaim, followed by an English translation that appeared in 2020. First, it is important to situate the lecture in its historical and political context, and to relate it to Adorno’s status as a critical theorist in West Germany. Secondly, Adorno’s diagnosis of the new right-wing extremism (and related forms of populism) and his conclusions about how to …

Covid-19 Is Spatial: Ensuring That Mobile Big Data Is Used For Social Good, Age Poom, Olle Järv, Matthew Zook, Tuuli Toivonen

Geography Faculty Publications

The mobility restrictions related to COVID-19 pandemic have resulted in the biggest disruption to individual mobilities in modern times. The crisis is clearly spatial in nature, and examining the geographical aspect is important in understanding the broad implications of the pandemic. The avalanche of mobile Big Data makes it possible to study the spatial effects of the crisis with spatiotemporal detail at the national and global scales. However, the current crisis also highlights serious limitations in the readiness to take the advantage of mobile Big Data for social good, both within and beyond the interests of health sector. We propose …

“You Cannot Slaughter Ideas”: Liberalism And The State Of Exception In Argentina, Arlo Elliott

disClosure: A Journal of Social Theory

Existing historiography of Latin America has highlighted the role of liberalism in the 19th century formation of modern states, but it is typically viewed as historically discontinuous with the subsequent violence of the 20th century. Narrowing the focus to Argentina, we see historians like Jeremy Adelman asserting that the promise and successes of the early liberal republics were historically isolated from the brutal military rule that would emerge following the Peronist era. More intellectual histories of Argentina like David Rock's Authoritarian Argentina also focus on the prominence of conservative nationalists in this period of violence. Incorporating the work of the …

Volume 29: Populism, Aimee Imlay, Matthew Wentz

disClosure: A Journal of Social Theory

The 2019-2020 disClosure collective is thrilled to present the 29th volume of disClosure: A Journal of Social Theory. This volume focuses on theories of populism and brings together a wide range of perspectives relating to the phenomenon, experience, and study of populism. The recent uptick in populism signals political, economic, and/or social unrest across the globe, yet, populism remains a phenomenon that is difficult to define. Our goal with this volume was not to define populism. Instead, this issue engages conversations about the various types and origins of populisms, as it is our belief that the development and definition …

Dynamic Modeling And Optimal Design For Net Zero Energy Houses Including Hybrid Electric And Thermal Energy Storage, Huangjie Gong, Vandana Rallabandi, Dan M. Ionel, Donald G. Colliver, Shaun Duerr, Cristinel Ababei

Power and Energy Institute of Kentucky Faculty Publications

Net zero energy (NZE) houses purchase zero net metered electricity from the grid over a year. Technical challenges brought forth by NZE homes are related to the intermittent nature of solar generation, and are due to the fact that peak solar generation and load are not coincident. This leads to a large rate of change of load, and in case of high PV penetration communities, often requires the installation of gas power plants to service this variability. This paper proposes a hybrid energy storage system including batteries and a variable power electric water heater which enables the NZE homes to …

Mobile Apps For Visual Research: Affordances And Challenges For Participant-Generated Photography, Sarah C. Barriage, Alison Hicks

The incorporation of participant-generated photography in research can be a powerful means of studying participants' perspectives and experiences. Approaches such as photovoice and photo-elicitation that incorporate participant-generated photography are increasingly being used in library and information science to study topics such as information needs, information seeking, and use of library space. This article describes two recent studies that used mobile apps (PixStori and EthOS) to facilitate participant-generated photography and photo-elicitation processes in research exploring the information practices of children and young adults, including the affordances, challenges and practical considerations identified by the researchers. Affordances of these apps within a research …

Patterns Of Inheritance Of Acylsugar Acyl Groups In Selected Interspecific Hybrids Of Genus Nicotiana, Antoaneta B. Mihaylova-Kroumova, Ivan Artiouchine, Victor D. Korenkov, George J. Wagner

Kentucky Tobacco Research and Development Center Faculty Publications

Glandular trichomes on the surface of Solanaceae species produce acyl sugars that are species-, and cultivar-specific. Acyl sugars are known to possess insecticidal, antibiotic, and hormone-like properties, and as such have great potential as a class of naturally occurring pesticides and antibiotics. The objective of this work was to analyze the acyl composition of acyl sugars in the leaf trichome exudate from selected Nicotiana species and to follow the inheritance of acyl content in their hybrids. Trichome exudates were collected, and the acyl profiles of acyl sugars were identified via GC–MS. The variations in acyl group inheritance in the hybrids …

Identifying Facets Of Reader-Generated Online Reviews Of Children’S Books Based On A Textual Analysis Approach, Yunseon Choi, Soohyung Joo

Information Science Faculty Publications

With the increasing popularity of social media, online reviews have become one of the primary information sources for book selection. Prior studies have analyzed online reviews, mostly in the domain of business. However, little research has examined the content of online book reviews of children’s books. Book reviews generated by book readers contain different aspects of information, such as opinions, feedback, or emotional responses, from the perspectives of readers. This study explores what aspects of the books are addressed in readers’ reviews, and then it intends to identify categorical features or facets of online book reviews of children’s books. We …
