Impaired Audiovisual Representation Of Phonemes In Children With Developmental Language Disorder, Natalya Kaganovich, Jennifer Schumaker, Sharon L. Christ

Purdue Center for Early Learning Faculty and Staff Publications

We examined whether children with developmental language disorder (DLD) differed from their peers with typical development (TD) in the degree to which they encode information about a talker’s mouth shape into long-term phonemic representations. Children watched a talker’s face and listened to rare changes from [i] to [u] or the reverse. In the neutral condition, the talker’s face had a closed mouth throughout. In the audiovisual violation condition, the mouth shape always matched the frequent vowel, even when the rare vowel was played. We hypothesized that in the neutral condition no long-term audiovisual memory traces for speech sounds would be …

Does Light Quality Influence Arabidopsis Thaliana Growth In Controlled Environments?, Nathan A. Deppe, Daniel A. Little, Kathleen K. Zapf

Purdue Methods for Arabidopsis Growth

This study examines the use of diverse lamp types, with inherently different spectral attributes, to determine light quality influence on Arabidopsis thaliana growth in controlled environments.

Changing The Process In Educational Field And Air Navigation Through Advances In Hologram Technology, Camilo Fernandez Sr.

Journal of Aviation Technology and Engineering

The objective of this piece is to propose reasons that change the way air traffic controllers and others learn and work in air navigation, but also how they can improve workloads, due to the implementation of holographic radar. This research also aims to describe how this could reduce the cognitive load of an operator, thanks to the improvement of visual perspective and capacity of analysis, in order to more easily control an aircraft.

Seeing that the visual facilitation is well known, radar is able to represent in three dimensions and in detail that which could not previously be perceived. This …

You Want Me To Teach Engineering? Impacts Of Recurring Experiences On K-12 Teachers’ Engineering Design Self-Efficacy, Familiarity With Engineering, And Confidence To Teach With Design-Based Learning Pedagogy, Shaunna Smith, Kimberly Talley, Araceli Ortiz, Vedaraman Sriraman

Journal of Pre-College Engineering Education Research (J-PEER)

This paper reports on findings from a group of ten teachers who were enrolled in a semester-long, graduate-level educational technology course that used design-based learning to explore the integration of making and the engineering design process into a variety of K-12 educational contexts. Using convergent mixed methods, this study examines how the course impacted teachers’ familiarity and confidence in teaching the engineering design process, as viewed through their pre- and post-semester engineering design self-efficacy scores and their weekly reflective journal entries. These measures are important factors for developing teacher experience and confidence in integrating engineering and design-based learning strategies within …

Possible Implications Of The European Carbon Border Adjustment Mechanism For Ukraine And Other Eu Trading Partners, Maksym Chepeliev

Department of Agricultural Economics Faculty Publications

This paper provides a quantitative assessment of the European Carbon Border Adjustment Mechanism (CBAM) implementation. We find limited impacts of the CBAM for most European Union (EU) trading partners. Ukraine is the most impacted country, with a per capita income change of -0.4% and reductions in domestic iron and steel production reaching 3.9%. Global exports of chemical products are impacted the most, with corresponding reductions exceeding 4% in some countries.

Provincializing New York: In And Out Of The Geopolitics Of Art After 1945, Béatrice Joyeux-Prunel

Artl@s Bulletin

In this article, I argue that the putative global centrality of New York in art after 1945 is a construct, as it is for Paris prior to 1945. Monographs and national approaches are unsuccessful in challenging such powerful myths as these. A global, transnational and comparative approach demonstrates that the struggle for centrality was a global phenomenon after 1945, a battle that New York does not win (depending on one’s point of view) until after 1964. Rather than considering centres and peripheries as a fixed category, I propose to consider them as a strategic notion which artists and their promoters …

Circulation Of Images, From Recognition To Erasure: An Artist’S Response, Lei Xie

Artl@s Bulletin

This article revolves around my practice, as an artist, which has an essential link with images and their circulation. In a subtle way, painting offers me a language allowing me to explore the polysemy of the chosen image, to experience a vocabulary both figurative and abstract. My practice could choose and process "ordinary" images, which are diffused but whose diffusion does not alter the subject, and has no consequence on the latter. It can also retain images whose strength is intrinsic to their circulation, to their popularization, to their controversy, images which will however ultimately generate paintings, and simultaneously erasing …

Un Mode D’Existence Équivoque Ce Que Touching Reality De Thomas Hirschhorn Dit De La Circulation Des Images., Pascale Borrel

Artl@s Bulletin

Les images en circulation que Thomas Hirschhorn utilise dans Touching Reality ont été trouvées sur Internet ; elles représentent des corps détruits dans le contexte de ce qui semble être les conflits au Moyen-Orient. Il s’agira de montrer comment l’œuvre reflète le mode d’existence initial de ces images : la manière dont elle les exhibe, dont elle les fait défiler laisse percevoir les conditions techniques dans lesquelles elles ont été faites et surtout le type de diffusion dont elles sont l’objet. La réalité qu’il s’agit de toucher est ici tributaire des opérations digitales produites sur la surface d’un écran ; …

Notes On The Circulation Of Epistemic Images, Nina Samuel

Artl@s Bulletin

Three cases of image circulation in the sciences, two from complex dynamics and one from microscopy, are discussed. The article deals with failed circulations, suspected errors, interdisciplinary communication, notebooks of scientists, the role of media shifts, mathematics and materiality, human perception, pictorial norms and conventions. It analyses how images circulate through different thought collectives and visual cultures. All three examples show different strategies of how images that break with visual traditions have been reintegrated into epistemic circulations and become “boundary objects” that are both robust and flexible.

Circularity And Visibility In Italian Art Periodicals (1968-1978), Denis Viva

Artl@s Bulletin

During the 1970s, at the apex of “dematerialized art”, the art magazines contributed a great deal to turn visibility (the photographic circulation of artworks, news on the artists, etc.) into an economic value. In a country like Italy, where museum validation was still lacking, neo-avantgarde periodicals such as Flash Art or Data introduced new communicative strategies (community building, indirect advertising, etc.) in order to provide a trans-national audience for Italian art. This study tries to enlighten the impact of advertising on art magazines’ preferences and their criteria of newsworthiness by analyzing some of their quantitative data.

To Let See. The Shocking Picture As A Social Mobilization Weapon, Beatriz Martínez Sosa

Artl@s Bulletin

This paper analyses the role that Emmett Till’s postmortem pictures had in the emergence of the modern civil rights movement. When they circulated in magazines, newspapers, and television in 1955, African Americans mobilized all over the U.S., so the pictures worked as a mobilization weapon. I intend to develop some hypotheses to explain this effect. To this end, the paper comprises four parts: an outline of the murder case; an analysis of the pictures’ formal and semantic features as well as the discourses and context where they were released; an examination of Till’s figure as a martyr through the effects …

How To Build A World Art: The Strategic Universalism Of Colour Reproductions And The Unesco Prize (1953-1968), Chiara Vitali

Artl@s Bulletin

What role did UNESCO play in the art world of the post-war era? This article makes use of published and archival sources in order to clarify the utopia of a “World Art” that shaped UNESCO and led to the “Archives of Colour Reproductions of Works of Art”, a project of worldwide collect and diffusion of images of “masterworks” inspired by Malraux’s “Museum without walls”. This case study focuses on one particular aspect of the project, the “UNESCO Prize”, conceived by the Brazilian art critic and Marxist intellectual Mario Pedrosa for the 1953 São Paulo Biennial.

The Copy & The Real Thing: Changing Perceptions Between The Rubens Centennials In 1877 And 1977, Griet Bonne

Artl@s Bulletin

In this paper I examine the changing relationship between mechanical reproductions and the original artwork in the context of the Rubens centennials in 1877 and 1977. Drawing on theorists such as Walter Benjamin, Dean MacCannell, Hans Belting and Boris Groys, I argue that the mechanism of copying generates a double logic of image perception: a simultaneous centrifugal and centripetal circulation of images that affects how people perceive art in modern society. I explore this perception dynamic by looking at two photo-exhibitions during the Rubens centennials.

Extensive And Intensive Iconography. Goethe’S Faust Outlined, Evanghelia Stead

Artl@s Bulletin

Drawing on a corpus of printed items between countries, compared first-hand, the article examines the mark left by Moritz Retzsch’s 26 outline etchings after Goethe’s Faust (1816) using the distinction between extensive and intensive iconography. In extensive iconography, copied or imitated images build a collective imagination, devaluing the original work, albeit contributing to the play’s aura. That view challenges Walter Benjamin’s influential essay on “The Work of Art in the Age of Mechanical Reproduction” (1935). In intensive iconography, inventive artists, inspired by Retzsch, rework images, granting a particular scene genuine reinterpretation. How then should we value multiples, copies and genuine …

Travelling Images In The Global Context: A Case Study Of The Short-Lived 18th Century Akita Ranga Painting School In Japan, Kuniko Abe

Artl@s Bulletin

By exploring early available travelling Western illustrations, image sources for the Akita Ranga painters in eighteenth century Japan, this article attempts to show how they developed, merging Japanese traditional Kano school aesthetics, new realistic Chinese trends for still-life images, and Western type illusionism, using Japanese traditional pictorial materials. The Akita Ranga school’s inventive compositional framework is the consequence of interaction with European models traced back to the famous Vesalius anatomy images with landscape, finally reaching Europe via Ukiyo-e prints, forming a full circle of the migration of images.

Sub Signo Capricorni. The Image Of Capricorn In Glyptics: Literary Sources, Gemstones, Impressions, Drawings, Alessandra Magni, Umberto Verdura, Gabriella Tassinari

Artl@s Bulletin

The relationship between glyptics and the circulation of images can be analysed from different perspectives, as seen in the case study of the image of Capricorn. The goat-fish monster entered the European collective imagination during Antiquity, when its image was spread on gems and coins. The popularity of this theme in the Augustan Age is unquestionable but, over time, the political meanings associated with Capricorn seemed to have faded, while others appeared. These meanings were fully recovered by 17^th century scholars through the analysis of famous cameos and lesser-known gems. However, the protective and magical value of gems with …

Behind The Circulations Of Images, Léa Saint-Raymond

Artl@s Bulletin

The history of images is nothing but a history of their mediums and a history of physical bodies. And hence, it is a history of circulation. As an introduction of this volume, this paper seeks to go "behind the circulations of images" by combining the fields of cultural, political and geopolitical studies, and by bringing together different methodologies from monographic and formal analysis to digital approaches (quantitative, cartographic, visual). These diversified case studies make it possible to answer three major questions: 1) How do images circulate? 2) Why do images circulate? 3) What does circulation do to an image and, …

Poro-Elastic Materials And The Control Of Low Frequency Sound, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

In the introductory sections of active noise control and metamaterial articles, it is often said that “conventional”, i.e., poro-elastic materials such as foams and fibrous media, do not work well at low frequencies. While that observation may be true for the simplest treatments, e.g., a single layer of a homogeneous, limp fibrous layer, there are many cases in which excellent weight and cost-effective acoustical treatments can be realized by using poro-elastic media. The first example involves the serendipitous discovery of a configuration that allows a 25 mm thick foam layer to provide effective absorption at 300 Hz, at a surface …

A Poro-Elastic Model For Activated Carbon Stacks, Zhuang Mo, Tongyang Shi, Seungkyu Lee, Yongbeom Seo, J. Stuart Bolton

Publications of the Ray W. Herrick Laboratories

Porous materials are widely applied in the field of noise control owing to their ability to attenuate transmission and/or reflection of sound. Among these materials, activated carbon is of increasing interest due to its excellent absorption performance at low frequencies. In 2016, a rigid, triple porosity model for granular activated carbon (GAC) was proposed by Venegas and Umnova. In the proposed model, a sorption process was introduced to account for the effect of the smallest scale pores, which is correlated with the high absorption at low frequencies. To extend that model to account for the finite frame stiffness of the …

Acoustical Investigation Of Aerogel Granules Modeled As A Layer Of Poroelastic Material, Yutong Xue, Amrutha Dasyam, J Stuart Bolton, Bhisham Sharma

Publications of the Ray W. Herrick Laboratories

Aerogels are defined as mesoporous materials obtained by replacing the liquid phase within a gel by a gaseous phase, typically air. This underlying mesoporous structure provides aerogels unique macrostructural properties such as ultralow density, high transparency, and low thermal conductivity. Given their ultralow density, aerogels are also an attractive, lightweight solution for noise control applications. Recent studies have shown that the acoustical properties of granular aerogels are very different from those observed for other granular media. In this presentation, we present results from our recent investigation of the acoustical behavior of Enova IC3100 aerogel granules. Manufactured and commercially sold by …

Information-Seeking On Coronavirus Disease 2019: Communication Factors Influencing Behavioral Intention, Seok Kang, Sophia Dave, Hyungjoon Kim

KAUPA Letters

This study examined how internal (uncertainty, susceptibility, severity, anxiety, and fear) and external motivators (descriptive norms, parasocial interaction, and identification) account for information seeking, message reception, and behavioral intentions to cope with COVID-19. A total of 500 U.S. adults’ responses were collected and analyzed. Results found that external motivators were significantly related to message reception whereas internal motivators were not. The finding that information seeking did not predict message reception implicates that both implicit and explicit confirmation processes are necessary to turn into behavioral intentions to cope with COVID-19.

Outdoor Adventure Practice In Kenya: Injuries, Illnesses, Non-Medical Concerns, And Evacuation Profiles On Mt. Kenya, Lucy Joy Wachira, Helen Nkatha Muthomi, Willy Shikuku Ooko

Journal of Human Performance in Extreme Environments

Background: Outdoor adventure is inevitably linked to risks that lead to injuries, psychological distress, illnesses, and even fatalities. Gathering detailed information on such occurrences and their contributing factors is a valuable component of risk management in outdoor programs. This study investigated the occurrence of injuries, illnesses, evacuation profiles, non-medical concerns, and near-miss events in outdoor adventure practice in Kenya.

Methods: A mixed-methods approach involving quantitative and qualitative methods was used to collect data from 136 outdoor adventure practitioners in Kenya. Questionnaires, key informant interviews, focus group discussions, and desk reviews were employed to collect data.

Results: The majority of injuries …

Applying Social Science To Bring Resident Stakeholders Into Pollution Governance: A Rural Environmental Justice Public Health Case Study, Sherrie M. Steiner, Jordan M. Marshall, Atefeh Mohammadpour, Aaron W. Thompson

Department of Horticulture & Landscape Architecture Faculty Publications

The purpose of this engaged public sociology study was to use social science to bring resident stakeholders into the process of governing pollution production in a rural community. The community has cancer clusters. Residents have concerns about direct exposure to pollution production in their neighborhood by a steel recycling plant that has been cited numerous times for environmental violations. The facility has been under voluntary remediation since 2009, but neighborhood residents were marginalized from the governance process. This case study details how social science was used to bring neighborhood residents’ concerns about direct exposure to toxic air pollution into remediation …

Pie/Decorative Pumpkin Cultivar Evaluation, Chris Smigell, John Strang, John Snyder, Emily Pfeufer, Bob Perry, Emily Dewitt

Midwest Vegetable Trial Reports

Fourteen pie and decorative pumpkin cultivars were evaluated in a replicated trial to determine their performance under Central Kentucky growing conditions. Plants were grown using standard commercial growing practices, using raised beds with trickle tube irrigation and fertigation, and covered with black plastic film. Fungicides and insecticides were applied following University of Kentucky Extension guidelines. Yields per-acre, fruit dimensions, weights and sugar contents were measured. Cultivars were also evaluated for visual attributes, such as size- and color uniformity and stem attractivness. Bisbee Gold’, ‘Baby Wrinkles’, ‘Darling’, ‘Fall Splendor Plus’, ‘Jack Sprat’, ‘Little Giant’ and ‘Cinnamon Girl’ were the best overall …

Nationalist Allegories In The Post-Human Era, Siqi Zhang

CLCWeb: Comparative Literature and Culture

As China’s expansion of influence now takes up the spotlight of the world stage, Chinese science fiction, a relatively little known genre, reaches a global audience. In 2015, Liu Cixin received the Hugo Award for Best Novel for his trilogy The Three-Body Problem, as the first Asian science fiction writer to receive the Hugo Award. A year later, Hao Jingfang’s Folding Beijing was awarded the 2016 Hugo Award for Best Novelette. The recent world-wide recognition of Chinese science fiction begins with English translation, U.S. publication and promotion. The New York Times cited The Three-Body Problem as having helped popularize Chinese …

Trans-Atlantic Interrogation: Fabienne Pasquet’S La Deuxième Mort De Toussaint Louverture, Mariana F. Past

CLCWeb: Comparative Literature and Culture

In “Trans-Atlantic Interrogation: Fabienne Pasquet’s La deuxième mort de Toussaint Louverture,” Mariana Past situates the Haitian-Swiss novelist’s understudied narrative within the context of Caribbean letters and the Haitian literary tradition, then discusses the broader, intertextual implications of Toussaint Louverture’s “second” death for Haiti and the trans-Atlantic world. To what end does Pasquet deploy the aged ghost of a Haitian revolutionary icon being invoked by German Romantic writer Heinrich von Kleist in the Fort de Joux castle-cum-prison within France’s remote, mountainous Jura region? What is at stake when the diasporic writer reincarnates a legendary German poet as protagonist, placing him …

From Franz Kafka To Franz Kafka Award Winner, Yan Lianke: Biopolitics And The Human Dilemma Of Shenshizhuyi In Liven And Dream Of Ding Village, Melinda Pirazzoli

CLCWeb: Comparative Literature and Culture

To date, many studies have exhaustively explained how and why Yan Lianke deals with both the intimate relationship between disease and biopolitics and the relationship between utopia and dystopia. These are certainly the most important themes in Liven (2004) and Dream of Ding Village (2006). However, biopolitical discourses cannot fully account for the complexity, depth and humanity of these novels, which in addition to exploring the complex and protean meaning of life also represent shenshizhuyi, an expression coined by Yan Lianke to describe his human dilemma in representing the complex relationship between shen 神 (soul, spirit, mind and myths) …

Hanay Geiogamah’S Body Indian And Foghorn As “Plays With A Purpose”, Danica Čerče

CLCWeb: Comparative Literature and Culture

In her article, “Hanay Geiogamah’s Body Indian and Foghorn as ‘Plays with a Purpose,’” written against the backdrop of critical whiteness studies, Danica Čerče discusses how Geiogamah’s theatrical rhetoric intervenes in the assumptions about whiteness as a static, privilege-granting category and system of dominance. By focusing on various techniques and strategies mobilized to define and affirm Native Americans’ authentic rather than imposed identities, the article shows that humor is one of the prime textual devices in Geiogamah’s plays to renegotiate what Walter Mignolo calls “the racist structure of power.”

Politics Of Evasion And Tales Of Abjection: Postmodern Demythologization In Angela Carter And Ghazaleh Alizadeh, Narges Montakhabi Bakhtvar, Hoda Niknezhad-Ferdos

CLCWeb: Comparative Literature and Culture

Angela Carter and Ghazaleh Alizadeh as the prophetesses of postmodern fairy tales in British and Persian literature re-narrativize these tales as a loophole from socio-political stagnation and cultural paralysis. Evading direct contact with the political jargons of their eras, they seek gender generativity via the fairy tale machine. Alizadeh finds refuge in modernizing Persian fairy tales. Carter chants her frustration at Thatcherism through gender subversion. Carter’s and Alizadeh’s revulsion at the politics of gender in their eras can be read via the duet between the abject and the chora in Kristeva’s thought. It is through the encounter with the external …

Strategies Of (In)Visibility And Resilience: Women Writers In A Digital Era, Miriam Borham-Puyal, Daniel Escandell-Montiel

CLCWeb: Comparative Literature and Culture

Women’s presence in literary history has been particularly conditioned by their place in society and by the limited spheres in which their production was expected to appear (e.g. the sentimental novel, romances or children’s literature). In today’s digital, open and connected society, women continue to face visibility problems in the publishing industry and in the online spaces that grant presence and agency. Their role in cultural creations is still hindered by vertical powers that operate as main censors. This circumstance takes place even in a rhizomatic and decentralized virtual space, where dissident discourses have highlighted it, although without enough discursive …
