“Hopes And Fears”: What Do Writing Center Administrators Think Of Merging With Or Converting Into A Learning Center?, Jenny Goransson Jan 2024

“Hopes And Fears”: What Do Writing Center Administrators Think Of Merging With Or Converting Into A Learning Center?, Jenny Goransson

The Writing Center Journal

This article shares findings from a survey study (n = 73) focused on writing center administrator (WCA) perceptions of two phenomena we see on many secondary and postsecondary campuses in recent years: writing centers expanding to become learning centers, and writing centers consolidating or merging with other tutoring services on campus. Through analysis of the qualitative, open-ended survey responses, the study revealed that WCAs’ views of these trends are greatly impacted by local conditions and levels of autonomy, as well as WCAs’ beliefs about expertise. Also, consolidation and expansion are seen by WCAs as shifting writing center identity in …

Slouching Towards Causality: Does Our Writing Center Tutoring Work?, Dennis Paoli, Jack Kenigsberg Jan 2024

Slouching Towards Causality: Does Our Writing Center Tutoring Work?, Dennis Paoli, Jack Kenigsberg

The Writing Center Journal

Replicable, aggregable, data-supported (RAD) research has become standard in writing center studies. Choice of research question is determined by local conditions and exigencies, often influenced by institutional assessment policy and national mandates. The methodology of choice in most writing center research is qualitative inquiry, though quasi-experimental quantitative studies, with their inherently difficult protocols and ethical problems, persist in their effort to address the question fundamental to writing center labor: Does writing center tutoring improve student writing? In a quasi-experiment applying propensity score matching to a sample of student users of the Rockowitz Writing Center at Hunter College of the City …

The Complexities Of Green Infrastructure, Troy Weber Dec 2023

The Complexities Of Green Infrastructure, Troy Weber

Purdue Journal of Service-Learning and International Engagement

The Wabash River is the most extensive river system in Indiana. The river drains two-thirds of Indiana’s 92 counties, which can have issues associated with stormwater runoff (Weist, 1981). As precipitation runs off impervious surfaces, it can carry high concentrations of pollutants, such as excess nitrogen and phosphorus, pet waste, and automobile fuel. Prior to impervious runoff entering the river, preexisting contaminants include industrial waste (acid mine drainage and oil field brines), municipal waste, and sediment (Weist, 1981). Thus, stormwater runoff can negatively impact the Wabash River watershed. On top of this pollution, Lafayette and West Lafayette have combined sewer …

If Men Can Do It, Then So Can A Woman: Inspiring Determination Through Service-Learning And Silent Movies, Kayla Vasilko

Purdue Journal of Service-Learning and International Engagement

In the American silent movie era, women were not associated with the ability to perform stunt work, drive an automobile without a man present, or be much more than a supporting face in a film, despite the fact that there were more female film writers, directors and producers than male in that era, the importance of “automotive citizenship,” and the added difficulty of women’s stunt work (women performed high risk stunts like jumping from buildings, etc., but they had to do it in gowns, and bikinis); today, women and minorities are highly under-represented in boardrooms, director’s chairs, and a startling …

Service-Learning In Action: Lafayette, Indiana, Rain Garden Installation, Elizabeth Mccleery

Purdue Journal of Service-Learning and International Engagement

Indiana’s Wabash River is being polluted with contaminated water runoff from precipitation events. A lack of pervious land cover has led to an accumulation of fertilizer, sediment, and waste in the river. Green infrastructure, a stormwater management practice that mimics the natural ecosystem, is one of the most effective ways to prevent pollution from stormwater runoff and benefit the community. This project consisted of a rain garden installation at the Lafayette Fueling Station, a site where frequent water drainage and water runoff into the Wabash occurs. The rain garden will allow on-site water infiltration during rain events and promote natural …

Resting-State Eeg Power Differences In Autism Spectrum Disorder: A Systematic Review And Meta-Analysis, Weisi Siong Neo, Dan Foti, Brandon Keehn, Bridgette Kelleher Dec 2023

Resting-State Eeg Power Differences In Autism Spectrum Disorder: A Systematic Review And Meta-Analysis, Weisi Siong Neo, Dan Foti, Brandon Keehn, Bridgette Kelleher

Purdue University Libraries Open Access Publishing Fund

Narrative reviews have described various resting-state EEG power differences in autism across all five canonical frequency bands, with increased power for low and high frequencies and reduced power for middle frequencies. However, these differences have yet to be quantified using effect sizes and probed robustly for consistency, which are critical next steps for clinical translation. Following PRISMA guidelines, we conducted a systematic review of published and gray literature on resting-state EEG power in autism. We performed 10 meta-analyses to synthesize and quantify differences in absolute and relative resting-state delta, theta, alpha, beta, and gamma EEG power in autism. We also …

Measuring Gas Discharge In Contact Electrification, Hongcheng Tao, James Gibert Dec 2023

Measuring Gas Discharge In Contact Electrification, Hongcheng Tao, James Gibert

Purdue University Libraries Open Access Publishing Fund

Contact electrification in a gas medium is usually followed by partial surface charge dissipation caused by dielectric breakdown of the gas triggered during separation of the surfaces. It is widely assumed that such discharge obeys the classical Paschen’s law, which describes the general dependence of the breakdown voltage on the product of gas pressure and gap distance. However, quantification of this relationship in contact electrification involving insulators is impeded by challenges in nondestructive in situ measurement of the gap voltage. The present work implements an electrode-free strategy for capturing discrete discharge events by monitoring the gap voltage via Coulomb force, …

Une Europe Par Les Arts ? Les Périodiques Illustrés Au-Delà Du Musée Imaginaire, Béatrice Joyeux-Prunel, Marie Barras, Nicola Carboni Dec 2023

Une Europe Par Les Arts ? Les Périodiques Illustrés Au-Delà Du Musée Imaginaire, Béatrice Joyeux-Prunel, Marie Barras, Nicola Carboni

Artl@s Bulletin

Existe-t- il un musée imaginaire européen ? Cet article aborde la question par le biais des illustrations de presse des années 1880-1960. Dans les périodiques illustrés de cette époque, les images d’art traversèrent mieux les frontières que les images non artistiques, en particulier en Europe. Mais plutôt que de conclure à un musée imaginaire européen, une étude multiscalaire plus fine incite à se pencher sur les facteurs sociaux, esthétiques, économiques et techniques de la circulation imprimée des images artistiques.

Mediatization Of The Early Automobile: A Visual Analysis Of The Illustrated Press In The Late 19th And Early 20th Century, Nicola Carboni Dec 2023

Mediatization Of The Early Automobile: A Visual Analysis Of The Illustrated Press In The Late 19th And Early 20th Century, Nicola Carboni

Artl@s Bulletin

The paper presents a digital analysis of automobile imagery in the early 20th-century press, examining the mediatization of the anti-car movement and the role images played in conveying and furthering the activist discourse. To investigate the phenomenon, the author compiled and analyzed over 5,000 images from in 185 journals published in 45 cities between 1891 and 1950. The analysis revealed a preponderance of positive representations of the automobile in the press, whilst evidence of negative sentiment towards the automobile, such as protests and accidents, was conspicuously absent, with the exception of satirical publications.

War And Peace. The Film Iconeme Of The Urban Square As Image Of Europe In Transition (1944-1948), Paolo Villa Dec 2023

War And Peace. The Film Iconeme Of The Urban Square As Image Of Europe In Transition (1944-1948), Paolo Villa

Artl@s Bulletin

A central feature of European urban landscapes, the square represents the public space par excellence. At the end of WW2 and in the immediate postwar time, the role of cinema in representing and reimagining urban squares was crucial. Through film images, they became the stage and the mirror of a Europe in transition. This contribution, examining Italian, French, German, and Czechoslovak cases, posits the square as an essential iconeme in postwar nonfiction cinema and visual culture, acting as a fil rouge to visually retrace the path of Europe from war to peace, and into new forms of political tension.

A Light On Europe. The International And Intermedial Trajectory Of A Medieval Chandelier At The Turn Of The Nineteenth Century, Eveline Deneer Dec 2023

A Light On Europe. The International And Intermedial Trajectory Of A Medieval Chandelier At The Turn Of The Nineteenth Century, Eveline Deneer

Artl@s Bulletin

This article investigates the shaping of European visual culture by tracing the international and intermedial trajectory of the visual motive of a chandelier from a 15th-century Burgundian manuscript in the decades around 1800. Passing from Brussels, Paris, Lyon, Mannheim, and Vienna to Coburg, and moving from illumination to drawing, archaeological illustration, painting, engraving to the applied arts, its trajectory exemplifies the historical conditions and cultural phenomena that animated the formation of a European visual culture, at a time when historical and national consciousness were developing on the continent.

The New World Debate And The 18th-Century Images Of America That Brought Europe Together, Catherine Dossin Dec 2023

The New World Debate And The 18th-Century Images Of America That Brought Europe Together, Catherine Dossin

Artl@s Bulletin

The New World Debate offers a privileged site to reconstruct and study Europe’s self-image in the 18th century. Taking on Buffon’s Histoire Naturelle, Rameau’s Les Indes Galantes, Voltaire’s Alzire et les Americains, and De Pauw’s Recherches philosophiques sur les Américains, this paper traces the process through which Europe elaborated a Eurocentric view of the world organization through a paternalistic, usually benevolent but always contemptuous, relation to America that would come to define Europe’s colonial expansion of the 19th century and make colonialism an essential, yet uncomfortable, dimension of Europe’s modern identity.

The Column And The Pediment: The Persistence Of Values?, Areti Adamopoulou Dec 2023

The Column And The Pediment: The Persistence Of Values?, Areti Adamopoulou

Artl@s Bulletin

There is one icon dispersed worldwide and historically associated with higher values: the façade of a columnated building capped by a pediment. This simple vertical, horizontal, and triangular formation runs through the ages and is firmly associated with values and ideas stemming from Europe. It survived centuries of use and abuse, and served revolutions, nation-states, democracies, colonialism, totalitarian regimes, and commercial culture. It even reached the world of computer graphic symbols and still inspires artists. In this paper, I discuss this icon in terms of its diffusion and persistency and comment upon its link to Europe.

Thinking Europe Visually. A Schizophrenic Certitude, Béatrice Joyeux-Prunel Dec 2023

Thinking Europe Visually. A Schizophrenic Certitude, Béatrice Joyeux-Prunel

Artl@s Bulletin

This article questions the existence of a shared European visual culture by examining how images circulated across the continent from the late nineteenth to the mid‑twentieth century. It revisits the post‑war concepts of Weltliteratur and Malraux’s Musée imaginaire, showing how they sought to ground European unity in culture despite their Western‑centric biases. Through the categories of witness images, constructed images, and circulating images, the text argues that visuals both reflect and shape European identities. Large‑scale analysis of illustrated press images (1880–1960) reveals that art images—especially religious motifs and reproductions—were the only visual content consistently circulating across Europe. The article …

A Critical Librarianship Approach For Teaching Patent Searching: Who Becomes An Inventor In America?, Dave Zwicky, Ilana Stonebraker Dec 2023

A Critical Librarianship Approach For Teaching Patent Searching: Who Becomes An Inventor In America?, Dave Zwicky, Ilana Stonebraker

Libraries Faculty and Staff Scholarship and Research

The ways in which a technology is invented, owned, and approved are strongly influenced by the same oppressive and exclusionary structures that critical librarianship interrogates. Patents, limited-term grants of rights to inventions, are issued to inventors in exchange for detailed specifications of the invention. This paper examines current practices used by business librarians in teaching students how to find patents and how these practices could be critically informed given the nature of the United States patent system as it exists today. An output of this work is a suggested lesson plan with recommended resources.

Organ-Specific Characteristics Govern The Relationship Between Histone Code Dynamics And Transcriptional Reprogramming During Nitrogen Response In Tomato, Russell Julian, Ryan M. Patrick, Ying Li Dec 2023

Organ-Specific Characteristics Govern The Relationship Between Histone Code Dynamics And Transcriptional Reprogramming During Nitrogen Response In Tomato, Russell Julian, Ryan M. Patrick, Ying Li

Purdue University Libraries Open Access Publishing Fund

Environmental stimuli trigger rapid transcriptional reprogramming of gene networks. These responses occur in the context of the local chromatin landscape, but the contribution of organ-specific dynamic chromatin modifications in responses to external signals remains largely unexplored. We treated tomato seedlings with a supply of nitrate and measured the genome-wide changes of four histone marks, the permissive marks H3K27ac, H3K4me3, and H3K36me3 and repressive mark H3K27me3, in shoots and roots separately, as well as H3K9me2 in shoots. Dynamic and organ-specific histone acetylation and methylation were observed at functionally relevant gene loci. Integration of transcriptomic and epigenomic datasets generated from the same …
