Unsorted Significance: Examining Potential Pathways To Extreme Political Beliefs And Communities On Reddit, Marcus Mann, Diana Zulli, Jeremy Foote, Emily Ku, Emily Primm

Purdue University Libraries Open Access Publishing Fund

Violent political extremists often point to online communities as motivating their behavior. However, researchers studying online exposure to extremism through structural mechanisms such as algorithms have not found strong evidence of their influence. At the same time, models of offline radicalization processes emphasize the importance of personal motivations, such as desire for significance and community, but do not fully account for online contexts. The authors integrate these approaches, which are both interested in worsening political extremism, asking, (1) What are the pathways to extreme content and communities online? and (2) What are the perceptions of extremism in online communities? Through …

A Literary Survey On The Challenges Of Adopting Lean In Aerospace Production And Aviation Maintenance, Seanan C. Lee

Journal of Aviation Technology and Engineering

Lean production began as a new method for creating value through the elimination of waste, continuous process improvement by workers, and fostering respect for people. Despite its success in other industries, the significantly lower production volume, the substantially higher complexity, and the service-oriented nature of aviation maintenance demand significant adaptation of Lean principles to be effective. The lack of a holistic study on Lean adoption for aerospace production and aviation maintenance organizations hinders transformation as the two industries are intertwined in product and characteristics. Lean adoption in aerospace production is hindered by the lingering notion that it is an ‘‘automotive …

Automated Delineation Of Visual Area Boundaries And Eccentricities By A Cnn Using Functional, Anatomical, And Diffusion-Weighted Mri Data, Noah C. Benson, Bogeng Song, Toshikazu Miyata, Hiromasa Takemura, Jonathan Winawer

MODVIS Workshop

Delineating visual field maps and iso-eccentricities from fMRI data is an important but time-consuming task for many neuroimaging studies on the human visual cortex because the traditional methods of doing so using retinotopic mapping experiments require substantial expertise as well as scanner, computer, and human time. Automated methods based on gray-matter anatomy or a combination of anatomy and functional mapping can reduce these requirements but are less accurate than experts. Convolutional Neural Networks (CNNs) are powerful tools for automated medical image segmentation. We hypothesize that CNNs can define visual area boundaries with high accuracy. We trained U-Net CNNs with ResNet18 …

Simulating Electrified Powertrain Noise And Vibration Measurement Signals For Machine Learning Based Fault Diagnosis Applications, Joohyun Lee, Yangfan Liu, J Stuart Bolton, Patricia Davies

Publications of the Ray W. Herrick Laboratories

Machine learning classification is a common method for vehicle noise and vibration (N&V) fault diagnosis which helps improve vehicle safety, comfort, and reduce maintenance cost. To improve the accuracy of classification, the model requires sufficient training data which is often expensive and time-consuming to acquire. A possible solution to resolve this limitation is to extract representative features from measurement signals and generate realistic simulated signals based on a smaller set of high-quality N&V measurement signals. A method to simulate N&V measurement signals of rotating machineries such as electrified powertrains is proposed. In its feature extraction process, tonal and broadband components …

Downstream Effects: Impact Of Antibiotic Pollution On An Aquatic Host-Parasite Interaction, Hannah G. Melchiorre, Stephanie O. Gutierrez, Dennis J. Minchella, Jing Trevor Vannatta

Purdue University Libraries Open Access Publishing Fund

The global increase in antibiotic use has led to contamination of freshwater environments. Despite the identified impacts of antibiotics on humans and wildlife, the effect of antibiotics on host–parasite life cycles in freshwater is relatively unexplored. In the current study, we utilize the trematode parasite Schistosoma mansoni, and its snail intermediate host, Biomphalaria glabrata, to investigate the influence of an ecologically relevant antibiotic concentration on the life history characteristics of both parasite and host. Our results demonstrate that antibiotics not only accelerate parasite development time, but also increase host reproduction and delay parasite-induced host castration. Using a mathematical …

Coronal Mass Ejections, Alex Echeverria

American Journal of Rising Scholar Activities

The underlying dynamics of solar processes are a topic of considerable interest, because the events on the surface of the Sun directly affect the environment of our planet. Certain ‘storms’ that erupt in the outer layers of the Sun can propel masses of electrically charged plasma into the solar system. If the path of that material crosses Earth’s orbit, it can disrupt our societal electronic and satellite resources. Observing and analyzing these events is a first step toward predicting them and hardening our equipment against them. This work reviews how solar scientists collect and view this data on coronal mass …

U-No: U-Shaped Neural Operators, Md Ashiqur Rahman, Zachary E Ross, Kamyar Azizzadenesheli

Department of Computer Science Faculty Publications

Neural operators generalize classical neural networks to maps between infinite-dimensional spaces, e.g., function spaces. Prior works on neural operators proposed a series of novel methods to learn such maps and demonstrated unprecedented success in learning solution operators of partial differential equations. Due to their close proximity to fully connected architectures, these models mainly suffer from high memory usage and are generally limited to shallow deep learning models. In this paper, we propose U-shaped Neural Operator (U-NO), a U-shaped memory enhanced architecture that allows for deeper neural operators. U-NOs exploit the problem structures in function predictions and demonstrate fast training, data …

Acanthamoeba species, Naegleria fowleri, and Balamuthia mandrillaris are opportunistic pathogens that cause a range of brain, skin, eye, and disseminated diseases in humans and animals. These pathogenic free-living amoebae (pFLA) are commonly misdiagnosed and have sub-optimal treatment regimens which contribute to the extremely high mortality rates (>90%) when they infect the central nervous system. To address the unmet medical need for effective therapeutics, we screened kinase inhibitor chemotypes against three pFLA using phenotypic drug assays involving CellTiter-Glo 2.0. Herein, we report the activity of the compounds against the trophozoite stage of each of the three amoebae, ranging from …

Critical Nematic Correlations Throughout The Superconducting Doping Range In Bi2−Zpbzsr2−Ylaycuo6+X, Can-Li Song, Elizabeth J. Main, Forrest Simmons, Shuo Liu, Benjamin Phillabaum, Karin A. Dahmen, Eric W. Hudson, Jennifer E. Hoffman, Erica W. Carlson

Purdue University Libraries Open Access Publishing Fund

Charge modulations have been widely observed in cuprates, suggesting their centrality for understanding the high-Tc superconductivity in these materials. However, the dimensionality of these modulations remains controversial, including whether their wavevector is unidirectional or bidirectional, and also whether they extend seamlessly from the surface of the material into the bulk. Material disorder presents severe challenges to understanding the charge modulations through bulk scattering techniques. We use a local technique, scanning tunneling microscopy, to image the static charge modulations on Bi2−zPbzSr2−yLayCuO6+x. The ratio of the phase correlation length ξ …

Self-Aligned Single-Electrode Actuation Of Tangential And Wineglass Modes Using Pmn-Pt, Ozan Erturk, Kilian Shambaugh, Ha-Seong Park, Sang-Goo Lee, Sunil Ai Bhave

Purdue University Libraries Open Access Publishing Fund

Considering the evolution of rotation sensing and timing applications realized in micro-electro-mechanical systems (MEMS), flexural mode resonant shapes are outperformed by bulk acoustic wave (BAW) counterparts by achieving higher frequencies with both electrostatic and piezoelectric transduction. Within the 1–30 MHz range, which hosts BAW gyroscopes and timing references, piezoelectric and electrostatic MEMS have similar transduction efficiency. Although, when designed intelligently, electrostatic transduction allows self-alignment between electrodes and the resonator for various BAW modes, misalignment is inevitable regarding piezoelectric transduction of BAW modes that require electrode patterning. In this paper transverse piezoelectric actuation of [011] oriented single crystal lead magnesium niobate–lead …

Don’T “Just Google It”: Deweyan Perspectives On Participatory Learning With Online Tools, Eric Thomas Weber, Heather Cowherd, Mia Morales

Education and Culture

John Dewey argued that for education to be democratic, it is important for students to be not merely spectators but also participants in learning. Teachers sometimes find personal computing devices to be distracting or to contribute to passivity rather than activity in the classroom. In this essay we examine the question of whether a student’s Google search on a subject matter discussed in class is participatory or passive. We argue that with proper guidance students’ use of online searches and related tools can empower students democratically as sources of ideas, conceptualizations, information, and insight while emphasizing participation in deliberation and …

Information And Communications Technologies And Democratic Education: Lessons From John Dewey's Pragmatism, Jonathan Flowers

Education and Culture

This essay applies lessons from John Dewey’s theory of democracy and democratic education to the modern development of information communications technologies and the assertion that the development of such technologies will lead to a more open, more democratic society. Given the continuity of the technology and its applications with structures of oppression within modern society, any attempt to resolve or democratize technology through skills-based training is bound to fail, as this does not resolve the cultural habits that enable oppression through technology. To this end, what is necessary is democratic education that recognizes the unique contexts in which students become …

Challenges In Education: A Deweyan Assessment Of Ai Technologies In The Classroom, Ande Eitner

Education and Culture

Artificial intelligence is profoundly transforming the world in various spheres and already finding its way into educational institutions. This essay aims to examine whether the Deweyan ideal of education can be achieved through such digital means. By analyzing how both the aims and means of education, as defined by Dewey, can be understood in the context of learning with artificial intelligence, the inherent differences of both educational approaches are brought out. It becomes apparent that important concepts that characterize successful education for Dewey, such as intrinsic inquiry, experience-based schooling, and thinking as the method for learning, do not go hand …

Data And Growth In Education: A Deweyan Analysis, Kevin Taylor

Education and Culture

For Dewey, growth in the educative process means education that enriches and expands one’s experience as it prepares students for not only a vocation but also entry into and transaction with the world. In few places can we see growth, generally understood, to be occurring as fast as in big data technology. This essay begins with an overview of what big data is, specifically what big data looks like in education as understood through learning management system platforms but also data as understood generally on a college campus through dataveillance, or data surveillance understood as the monitoring or possibility of …

Transtrauma: Conceptualizing The Lived Experiences Of Vietnamese American Youth, Khánh Lê

Journal of Southeast Asian American Education and Advancement

Drawing on empirical data from qualitative research I conducted with eight Vietnamese American youth in the Fall of 2020, this paper forwards transtrauma, a new framework for conceptualizing and understanding the lived experiences of Vietnamese American youth. The concept of transtrauma goes beyond the pathologizing of individual trauma, to examine how structures of domination inflict and extend trauma in marginalized communities, such as that of Vietnamese American communities. Transtrauma transcends the overt and linear focus on trauma as a single experience and the examination of how institutionalized violence by nation states shapes the experiences of Vietnamese Americans. This conceptualization …

An Ethical Framework For Library Publishing Version 2.0, Tina Baich, Nina Collins, Jaime Ding, Abigail Gulya, Zoe Wake Hyde, Bernadette A. Lear, Joshua Neds-Fox, Charlotte Roh, Melanie Schlosser, Kate Shuttleworth, Christine Turner

LPC Publications

Conceived at the Library Publishing Forum in 2017, the Ethical Framework for Library Publishing was a first-of-its-kind document for the LPC and the library publishing community. But remarkable social upheaval in the ensuing years, along with the continued maturation of our discipline, prompted the LPC to convene a task force to update the Framework for our current environment. What the task force developed, to our surprise, looks very little like the original document. An Ethical Framework for Library Publishing Version 2.0 is a true framework to help library publishers set an ethical baseline for their programs and activities. Consisting of …

Global-To-Local-To-Global Interactions And Climate Change, Uris Baldos, Maksym Chepeliev, Brian Cultice, Matthew Huber, Sisi Meng, Alex C. Ruane, Shellye Suttles, Dominique Van Der Mensbrugghe

Department of Agricultural Economics Faculty Publications

Climate change by its very nature epitomizes the necessity and usefulness of the global-to-local-to-global (GLG) paradigm. It is a global problem with the potential to affect local communities and ecosystems. Accumulation of local impacts and responses to climate change feeds back to regional and global systems creating feedback loops. Understanding these complex impacts and interactions is key to developing more resilient adaptation measures and designing more efficient mitigation policies. To this date, however, GLG interactions have not yet been an integrative part of the decision-support toolkit. The typical approach either traces the impacts of global action on the local level …

Glioblastoma (GBM) is one of the most aggressive and lethal solid tumors in human. While efficacious therapeutics, such as emerging chimeric antigen receptor (CAR)-T cells and chemotherapeutics, have been developed to treat various cancers, their effectiveness in GBM treatment has been hindered largely by the blood-brain barrier and blood-brain-tumor barriers. Human neutrophils effectively cross physiological barriers and display effector immunity against pathogens but the short lifespan and resistance to genome editing of primary neutrophils have limited their broad application in immunotherapy. Here we genetically engineer human pluripotent stem cells with CRISPR/Cas9-mediated gene knock-in to express various anti-GBM CAR constructs with …
