Flight Testing Gls Approaches Enabled By Wide Area Corrections In Kerkyra, Greece, Thomas Dautermann, Thomas Ludwig

Journal of Aviation Technology and Engineering

Many airports with a high value to commercial air traffic have spatial or budgetary constraints which prevent the installation of a precision approach system. We previously designed a low-cost precision approach system which combines the advantages of both ground-based and satellite-based augmentation systems by using a converter between them in order to allow GAST-A approach types. We installed, operated, and flight-tested such a system at Kerkyra Airport using an A320 aircraft. During these, we recorded data from a commercial multimode receiver as well as GPS raw data in order to prove the feasibility of the system. Data were analyzed using …

The electrochemical instability of ether-based electrolyte solutions hinders their practical applications in high-voltage Li metal batteries. To circumvent this issue, here, we propose a dilution strategy to lose the Li+/solvent interaction and use the dilute non-aqueous electrolyte solution in high-voltage lithium metal batteries. We demonstrate that in a non-polar dipropyl ether (DPE)-based electrolyte solution with lithium bis(fluorosulfonyl) imide salt, the decomposition order of solvated species can be adjusted to promote the Li+/salt-derived anion clusters decomposition over free ether solvent molecules. This selective mechanism favors the formation of a robust cathode electrolyte interphase (CEI) and a solvent-deficient electric double-layer structure at …

The Nazis, The Vatican, And The Jews Of Rome, Patrick J. Gallo

Purdue University Press Books

On October 16, 1943, the Jews of Rome were targeted for arrest and deportation. The Nazis, the Vatican, and the Jews of Rome examines why—and more importantly how—it could have been avoided, featuring new evidence and insight into the Vatican’s involvement. At the time, Rome was within reach of the Allies, but the overwhelming force of the Wehrmacht, Gestapo, and SS in Rome precluded direct confrontation. Moral condemnations would not have worked, nor would direct confrontation by the Italians, Jewish leadership, or even the Vatican.

Gallo underscores the necessity of determining what courses of actions most likely would have spared …

Covid-19 As A Magnifying Glass: Exploring The Importance Of Relationships As Education Students Learn And Teach Robotics Via Zoom, Jennifer Kidd, Krishnanand Kaipa, Kristie Gutierrez, Min Jung Lee, Pilar Pazos, Stacie I. Ringleb

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

Ed+gineering, an NSF-funded program, adapted hands-on robotics instruction for online delivery in response to the COVID-19 pandemic. This qualitative multiple case study shares the experiences of participating education students in spring 2021 as they collaborated virtually with engineering students and fifth graders to engineer bioinspired robots in an afterschool technology club adapted to be virtual. The online context reduced the education students’ interactions with people other than the engineering students and fifth graders on their team and thus positioned COVID-19 as a metaphorical magnifying glass amplifying the critical role that these relationships played in influencing the project’s outcomes. Through analyzing …

From In-Person To Virtual: A Case Study Of An Animal-Assisted Visiting Program In A Pediatric Setting, Whitney Romine

People and Animals: The International Journal of Research and Practice

This article focuses on the practical aspects of converting a successful in-person AAA program to a virtual program in a health care setting including human, canine, and physical resources; animal welfare considerations; training, infection control, and safety guidelines; and visit delivery procedures. In 1992, an interdisciplinary team at Akron Children’s Hospital founded the Doggie Brigade, an animal-assisted activities (AAA) program where volunteer therapy dogs and their handlers visit pediatric patients. The program has become a cornerstone of the hospital’s culture over its now 30-year tenure. In March 2020, the announcement of the COVID-19 pandemic forced health care organizations to suspend …

Interactions Between Humans And Dogs During The Covid-19 Pandemic: Recent Updates And Future Perspectives, Mohamed S. Kamel, Amr A. El-Sayed, Rachel A. Munds, Mohit S. Verma

Purdue University Libraries Open Access Publishing Fund

COVID-19 is one of the deadliest epidemics. This pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but the role of dogs in spreading the disease in human society is poorly understood. This review sheds light on the limited susceptibility of dogs to COVID-19 infections which is likely attributed to the relatively low levels of angiotensin-converting enzyme 2 (ACE2) in the respiratory tract and the phylogenetic distance of ACE2 in dogs from the human ACE2 receptor. The low levels of ACE2 affect the binding affinity between spike and ACE2 proteins resulting in it being uncommon for dogs to …

Understanding How Regulatory And Ethical Principles Mitigate The Spread And Propagation Of Harmful Health Information: A Successful Fulbright Scholar Award Narrative, Bethany S. Mcgowan

Libraries Faculty and Staff Creative Materials

I used a Fulbright Scholar Award to work with librarians, information studies scholars, and policymakers in Finland to investigate what policies or policy tools were available to help balance the need between propagating accurate information, curbing dis/misinformation, and ensuring human rights of access to information. This policy assessment helped me understand how regulatory and ethical principles can mitigate the spread and propagation of harmful health information.

Abrupt Shift Or Caught Off Guard: A Systematic Review Of K-12 Engineering And Stem Education’S Response To The Covid-19 Pandemic, Ibrahim Delen, Tugba Yuksel

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

In the past hundred years, there have been a number of pandemics that have affected the entire world, including the 1918 H1N1 influenza pandemic, the 1957 H2N2 influenza pandemic, and the 2009 H1N1 influenza pandemic. While responses to the most recent H1N1 influenza pandemic remained local, the COVID-19 pandemic, on the other hand, resulted in long-term school closures all around the world, prompting a sudden shift to distant education by compelling K-12 educators and students to do so. The purpose of this study is to find out how K-12 education studies reacted to the sudden shift in supporting engineering and …

“For The Moment, I Am Not F*Cking,” I Am Tweeting: Platforms Of / As Sexuality, Jacob Johanssen

CLCWeb: Comparative Literature and Culture

This article develops the argument that digital platforms are significantly infused with originary (and unconscious) residues of the sexual. Drawing on Laplancheian conceptualizations of sexuality, I argue that the digital has always been sexual(ised) in itself – a process that precedes and exceeds the erotic or pornographic. For Laplanche, sexuality is constitutive of the human subject as such. Infantile sexuality is shaped and transformed in an enigmatic relation with the caregiver. Drawing on this model as an analogy, I claim that users are drawn to platforms because they (unconsciously) desire to return to infantile sexuality and a holding environment but …

Amazon Web Services, The Lacanian Unconscious, And Digital Life, Marshall N. Armintor

CLCWeb: Comparative Literature and Culture

In late 2011, ex-Amazon developer Steve Yegge’s rant about his former company described Amazon’s rapid transformation from an online bookstore to a web-services entity with a ruthlessly unified platform, all guided by the idea that the company’s effort to streamline its internal efficiency could be monetized, and the resultant software products sold through Amazon Web Services. The media consumerism that fed Amazon’s early years funded a surveilling behemoth, one that everyone feared Microsoft would become. As such, AWS has become a manifestation of the internet’s Lacanian unconscious (even providing the services and hosting for Reddit), structured around the optimization of …

Purloined Significance: How Recidivism Algorithms Capture, Transform, And Automate Our Intersubjective Unconscious As Data, Macy Mcdonald

CLCWeb: Comparative Literature and Culture

Ever since ProPublica published their groundbreaking analysis of Northpointe’s Correctional Offender Management Profiling for Alternative Sanctions Core Risk and Needs Assessment software (COMPAS) in 2016, this web-based decision support system (DSS) has spawned a wide range of critiques and charges of racial bias. COMPAS provides a full suite of decision support applications to the US prison-industrial complex, including algorithmically derived recidivism predictions that increasingly guide parole decisions. The larger conversation surrounding COMPAS raises the question of how we analyze powerful, and yet opaque, data assemblages. In this article, I model an allegorical analysis of data assemblages. I argue the skills …

Community Despite Connection: Resisting The Digital Logics Of Optimization And Failure, Irina Kalinka

CLCWeb: Comparative Literature and Culture

If a certain brand of aspirational tech-utopian discourse is to be believed, those privileged enough to be plugged into digital information technology are living through a golden age of connection. Platforms claim to facilitate sharing and partaking, bring people together, and bestow upon them new and improved spaces to gather and build communities. While reality differs decidedly from such idealized conceptions, it is nonetheless crucial to ask what kind of guiding vision is being instituted through such representational efforts: namely, the figure of community made operational and optimizable. This project will reject such idealized visions of coherent communities drawn together …

The Social Sinthome, Ryan Engley

CLCWeb: Comparative Literature and Culture

Much of the critical discourse on social media misidentifies its problematic features as bugs, or problems to solve. Supposed solutions to these problems tend to focus on individual actions. We should delete the apps, own our own data, never click on recommended videos, and realize that we are the product. But if predatory algorithms succeed by individuating people—selling people “choice” and “options” as it harvests user data—then an entire online ecosystem arranged through the logic of that design can neither be meaningfully challenged nor effectively understood at the level of the individual alone. Transformative action addressing social media can only …

#Emotional: Exploitation & Burnout In Creator Culture, Sarah Thorne

CLCWeb: Comparative Literature and Culture

In recent years, a growing list of content creators have published videos announcing that they are leaving YouTube, taking a break, or reducing their upload schedule (Alexander). Many of these young creators state that their decision resulted from burnout, caused by a relentless schedule and obsession with YouTube’s algorithm and analytics— tools essential to success on this highly competitive creative platform (Srnicek). Its opaque algorithm, however, induces anxiety; an affect described as that which “arises when the subject is confronted by the desire of the Other and does not know what object he is for that desire” (Evans 12). Here, …

Everybody Wants To Be A Fascist Online: Psychoanalysis And The Digital Architecture Of Fascism, Anthony Faramelli, Imogen Piper

CLCWeb: Comparative Literature and Culture

Félix Guattari and Franco Berardi have both argued that media ecologies and psychic ecologies are intimately intertwined and as such, any exploration of the collective unconscious must engage with how the mind is formed with and through media. This understanding of networks of interdependence necessitates an exploration of how platformization has impacted users” collective psyche. Drawing from psychosocial theory, psychoanalysis and the work of Félix Guattari, this article analizes the micropolitics of desire of digital platforms, with an explicit focus on how algorithmic structures amplify extreme Right content, allowing fascisms to metastasis throughout digital spaces. It will first examine the …

“There Is No Pandemic”: On Memes, Algorithms And Other Interpassive Forms Of Right-Wing Disbelief, Scott Krzych

CLCWeb: Comparative Literature and Culture

This essay examines several prominent memes that have circulated on Right-wing social media during the Covid-19 pandemic. The memes coordinate what I describe as a mode of interpassive humor, which positions those who “believe” in the crisis as naïve dupes, infantilizing those subjects who have fallen prey to the idea that they should take the pandemic seriously, and thereby delegating fearfulness to the other so that reactionary Covid-19 denialists may continue with their lives unaffected. The essay thereby seeks to draw suggestive lines of affiliation between studies of digital memes, evolutionary mimetics, and psychoanalytic theory, pointing to the algorithmic …

“Love Thy Social Media!”: Hysteria And The Interpassive Subject, Jack Black

CLCWeb: Comparative Literature and Culture

According to the 2020 docudrama, The Social Dilemma, our very addiction to “social media” has, today, become encapsulated in the tensions between its facilitation as a mode of interpersonal communication and as an insidious conduit for machine learning, surveillance capitalism and manipulation. Amidst a variety of interviewees – many of whom are former employees of social media companies – the documentary finishes on a unanimous conclusion: something must change. By using the docudrama as a pertinent example of our “social media malaise,” and while remaining aware of the problems and unethical practices encompassing international digital/social media companies, this paper …

Lacan And The Algorithm, Clint Burnham

CLCWeb: Comparative Literature and Culture

Exploring the development of algorithms in Lacanian theory, specifically the "R schema" in the 1950s, I argue that psychoanalysis, read through contemporary debates about the "algorithmic cult" of Netflix and other avatars of popular culture, can be said to reveal the inhuman, machinic essence of subjectivity. The etiology of algorithms, mathemes, and other formulae and diagrams in Lacan’s oeuvre has been under-studied, in part because for some readers they are not as attractive as his more bravura flourishes of word play as exegetical excess, and in part because they derive largely from the ‘hard’ structuralist moment of his work in …

Towards Generalization Of Deep Learning-Based Plant Disease Identification Under Controlled And Field Conditions, Aanis Ahmad, Aly El Gamal, Dharmendra Saraswat

Purdue University Libraries Open Access Publishing Fund

Identifying corn diseases under field conditions is crucial for implementing effective disease management systems. Deep learning (DL)-based plant disease identification using deep neural networks (DNN) has been successfully implemented in recent years. Recent work suggests DL models trained on lab-acquired image data do not generalize to similar accuracy levels for identifying diseases in the field. Additionally, most studies have not evaluated the generalizability of DL models for identifying plant diseases from various datasets and diverse imaging conditions. This study evaluates how well DL models generalize across different datasets and environmental conditions for identifying plant diseases using five datasets consisting of …

Serving The Underserved Amid Covid-19: The Case Of A Virtual, Culturally Responsive Summer Engineering Camp, Tonisha B. Lane, Eugenia Vomvoridi-Ivanovic, Leia K. Cain, Selene Willis, Salam Ahmad, Jonathan Gaines

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

The societal disruptions due to the novel coronavirus (COVID-19) pandemic are well noted, especially in the context of science, technology, engineering, and mathematics (STEM) education. Absent a concerted effort to sustain hands-on learning opportunities in STEM amid the crisis, the consequences of COVID-19 may exacerbate existing inequities and racial disparities among youth of color further stratifying the STEM fields. In the current study, we applied a mixed-method descriptive case study design, using online learning theory and culturally responsive pedagogy as our conceptual framework, to describe how participants experienced this camp, held online due to disruptions of COVID-19, in the southeastern …

Ethylene-Triggered Subcellular Trafficking Of Ctr1 Enhances The Response To Ethylene Gas, Hye Lin Park, Dong Hye Seo, Han Yong Lee, Arkadipta Bakshi, Chanung Park, Yuan-Chi Chien, Joseph J. Kieber, Brad M. Binder, Gyeong Mee Yoon

Purdue University Libraries Open Access Publishing Fund

The phytohormone ethylene controls plant growth and stress responses. Ethylene-exposed dark-grown Arabidopsis seedlings exhibit dramatic growth reduction, yet the seedlings rapidly return to the basal growth rate when ethylene gas is removed. However, the underlying mechanism governing this acclimation of dark-grown seedlings to ethylene remains enigmatic. Here, we report that ethylene triggers the translocation of the Raf-like protein kinase CONSTITUTIVE TRIPLE RESPONSE1 (CTR1), a negative regulator of ethylene signaling, from the endoplasmic reticulum to the nucleus. Nuclear-localized CTR1 stabilizes the ETHYLENE-INSENSITIVE3 (EIN3) transcription factor by interacting with and inhibiting EIN3-BINDING F-box (EBF) proteins, thus enhancing the ethylene response and delaying …

Exploring Barriers To The Adoption Of Internet Of Things-Based Precision Agriculture Practices, Gaganpreet Singh Hundal, Chad Laux, Dennis R. Buckmaster, Mathias J. Sutton, Michael Langemeier

Computer Information Technology Faculty Publications

The production of row crops in the Midwestern (Indiana) region of the US has been facing environmental and economic sustainability issues. There has been an increase in trend for the application of fertilizers (nitrogen & phosphorus), farm machinery fuel costs and decreasing labor productivity leading to non-optimized usage of farm inputs. Literature describes how sustainable practices such as profitability (return on investments), operational cost reduction, hazardous waste reduction, delivery performance and overall productivity might be adopted in the context of precision agriculture technologies (variable rate irrigation, variable rate fertilization, cloud-based analytics, and telematics for farm machinery navigation). The literature review …

Moving Beyond Dosage And Adherence: A Protocol For Capturing Dimensions Of Active Child Engagement As A Measure Of Fidelity For Social-Emotional Learning Interventions, Brianna L. Devlin, Tanya M. Paes, Elyssa A. Geer, Lindsey M. Bryant, Tracy M. Zehner, Irem Korucu, Kathleen Morse, Robert Duncan, David J. Purpura, Sara A. Schmitt

Purdue Center for Early Learning Faculty and Staff Publications

Social-emotional competencies are important for school-readiness and can be supported through social-emotional learning (SEL) interventions in the preschool years. However, past research has demonstrated mixed efficacy of early SEL interventions across varied samples, highlighting a need to unpack the black box of which early interventions work, under what conditions, and for whom. In the present article we discuss the critical implementation component of active child engagement in an intervention as a potential point of disconnect between the intervention as designed and as implemented. Children who are physically present but unengaged during an intervention may lead to decreased average impacts of …

A Scoping Review Of Campus-Based Animal-Assisted Interactions Programs For College Student Mental Health, Tanya K. Bailey

People and Animals: The International Journal of Research and Practice

Background: People have long found support by interacting with animals, which has developed into a health care modality called animal-assisted interactions (AAI). In the past 10 years, AAI has increased as a way to support college students’ mental health; however, there is no comprehensive evidence on the effectiveness of these programs.
Method: A scoping review was conducted using the JBI and PRISMA-ScR criteria. Empirical articles were identified through Academic Search Premier (EBSCOhost), PsychINFO (Ovid), and Web of Science using three groups of keywords: AAI, college students, and mental health.
Results: Of the 1,195 publications identified, 37 met this study’s eligibility …
