Development And Validation Of An Integrated Stem Teacher Classroom Observation Protocol, Shuqi Zhou, Hillary E. Merzdorf, Kerrie A. Douglas, Tamara J. Moore

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

This study aimed to develop a K-12 classroom observation protocol to assess K-12 teachers’ implementation of science, technology, engineering, and mathematics (STEM) integration. The intended purpose of the observation protocol is for researchers to examine how K-12 teachers implement the STEM integrated curriculum. Based on research on STEM integration, the protocol covers eight categories: Define, Learn, Plan, Try, Test, Decide, Improve, and Instructional Strategies. The protocol was reviewed by a panel of integrated STEM education experts, engineering design experts, and educational assessment experts (n = 15) and revised accordingly. To test the reliability of using the protocol, two …

The Simon Effect Asymmetry For Left- And Right-Dominant Persons, Robert W. Proctor, Qi Zhong, Jing Chen

Purdue University Libraries Open Access Publishing Fund

When participants respond to a task-relevant stimulus attribute by pressing a left or right key with the respective index finger, reaction time is shorter if task-irrelevant left-right stimulus location corresponds to that of the response key than if it does not. For right-handers, this Simon effect is larger for right-located than left-located stimuli; for left-handers this Simon-effect asymmetry is reversed. A similar asymmetry has been found for right-footers pressing pedals with their feet. For analyses that separate stimulus- and response-location factors, these asymmetries appear as a main effect of response location, with responses being faster with the dominant effector. If …

An Intervention To Promote Growth Mindset And Stem Self-Efficacy Of High School Students: Exploring The Complexity Of Beliefs, Amy Kramer, Emily Dringenberg, Carter Morris, Darcy Mccarthy

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

The marginalization of women in engineering is a persistent problem. The overall goal of our collaborative project was to promote interest and participation in science, technology, engineering, and mathematics (STEM), particularly for high school girls. We took an action research approach with a local high school science teacher to develop, implement, and research the impact of a classroom-based intervention designed to encourage growth mindset and STEM self-efficacy beliefs using mixed methods. We analyzed pre- and postsurvey data collected using a control-treatment design to determine the impact of the intervention on high school boys’ and girls’ self-efficacy and mindset beliefs. We …

Recognition Of Design Failure By Fourth-Grade Students During An Engineering Design Challenge, Ron K. Skinner, Danielle B. Harlow

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

The practice of persisting and learning from design failures is essential to engineering design and offers unique ways of knowing and learning for K-12 students. To understand how students engage in the practice of persisting and learning from design failures, we must first understand how, if at all, they recognize that a design failure has occurred. We studied a classroom of fourth-grade students engaged in an engineering design challenge and examined the ways in which design failure occurred and how students recognized, neglected to recognize, or misinterpreted design failure. We found that, in addition to anticipating failure, conducting fair tests, …

Student Information Use During The Covid-19 Pandemic, Heather A. Howard, Annette Bochenek, Zoeanna A. Mayhook, Trena Trowbridge, Steven Lux

Libraries Faculty and Staff Scholarship and Research

Since early 2020, life for students has changed tremendously. It has been a time of stress, turmoil, and trauma for students. Researchers from a large Midwestern university wanted to determine how student information use has changed during the COVID-19 pandemic. This paper examines the results of a mixed-methods study undertaken in 2021 using surveys and follow-up focus groups to determine if and how student information use has changed. To answer this, we explored student use of news sources, social media sources, political affiliations, and information responses, coupled with to what extent these factors demonstrate or impact potential changes in information …

Data On Data: An Analysis Of Data Usage And Analytics In The Agricultural Supply Chain, Lourival Carmo Monaco Neto, Brady Brewer, Allan Gray

Department of Agricultural Economics Faculty Publications

The amount of data being collected throughout the agricultural supply chain has increased in both volume and velocity. All signs indicate that this will only increase as data collection technologies become more cost effective and prevalent throughout the supply chain. Previous work in this area has focused on data collection at the farm level. Our study focuses on data that originates at five different stages of the agricultural supply chain off the farm and how these stages view their firm's data collection and analysis efforts. We find that there is heterogeneity in the data collection efforts and analysis across the …

Bergson On Poetics: Philosophy, Literature And Science, Michel Dalissier

CLCWeb: Comparative Literature and Culture

In this paper, I analyze Henri Bergson’s insightful and contrasted vision of poetry. First, I show in what sense Bergson sympathizes with the idea that the poet must be credited to surpass the novelist in offering to us an unparalleled emotional apprehension of the world. Second, I nonetheless underline how Bergson grants the product of the poet, i.e., the poem itself, a problematic linguistic status, inasmuch as the focus of his analysis shifts from an intersubjective poetical apprehension of feelings to their individual poetic appreciation, or from the spiritual dimension of poetry to its material dimension. Third, I further suggest …

Language, Science And Literature, Hitoshi Oshima

CLCWeb: Comparative Literature and Culture

The creativity of language Chomsky puts so much importance on must be questioned because the same creativity has produced lethal weapons such as atomic bombs. Modern science developed by the power of language has certainly produced many beneficial things, but we should not overlook its destructive side. Besides, language capable of inventing a new reality leads us to believe in it blindly. Let us remember philosophers such as Wittgenstein or Nagarjuna who warned us not to believe in the construct called “reality” made up by language power.Now, is it better and safer then to use a metaphorical language that composes …

Orature: The Political Interpretation Of Performance Framework In Anthills Of The Savannah And Half Of A Yellow Sun, Jing Duan

CLCWeb: Comparative Literature and Culture

The focus of discussion in this paper lies in a perception that orature of African written literature is not innocent but a form of control. Operated through its performance framework, the concept of orature provides an angle to observe how African oral tradition penetrates written literature and cultivates an awareness of the political nature both of the material to be written and of the writing process itself. This paper explores the performance framework in two African novels — Achebe’s Anthills of the Savannah and Adichie’s Half of a Yellow Sun. Through such key concepts as event, narrative and self-reflexivity …

Political Orientation In Ecocriticism: National Allegory In Vietnamese Ecofiction By Trần Duy Phiên, Chi P. Pham

CLCWeb: Comparative Literature and Culture

Since the late 1990s, theories and practices of ecocriticism have tended to be more politically engaged than in its earliest phase, considering that “environmental problems cannot be solved without addressing issues of wealth and poverty, overconsumption, underdevelopment, and the notion of resource scarcity” (Heise 251-2). This paper engages with the political orientation in ecocriticism by examining presentations of humans and nature in three Vietnamese short stories – “Kiến và người” (The Ants and the Man, 1990), “Mối và người” (The Termite and the Man, 1992), and “Nhện và người” (The Spider and the Man, 2012) by Trần Duy Phiên (born …

Local, Regional, And Global Adaptations To A Compound Pandemic-Weather Stress Event, Iman Haqiqi, Danielle S. Grogan, Marziyeh Bahalou Horeh, Jing Liu, Uris Baldos, Richard Lammers, Thomas W. Hertel

Department of Agricultural Economics Faculty Publications

Global food security can be threatened by short-term extreme events that negatively impact food production, food purchasing power, and agricultural economic activity. At the same time, environmental pollutants like greenhouse gases (GHGs) can be reduced due to the same short-term extreme stressors. Stress events include pandemics like COVID-19 and widespread droughts like those experienced in 2015. Here we consider the question: what if COVID-19 had co-occurred with a 2015-like drought year? Using a coupled biophysical-economic modeling framework, we evaluate how this compound stress would alter both agricultural sector GHG emissions and change the number of undernourished people worldwide. We further …

Simplified Demonstration Of A New Perivascular Pump Mechanism For Glymphatic Flow Of Interstitial Fluid In The Brain, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

In a previous paper the author presented details of a new mechanism for the perivascular pump driving glymphatic flow—the brain’s waste removal system. The goal was to capture the essence of complex three-dimensional anatomy and physiology of the brain in a reduced order geometric model. The complexity required to make the model even approximately brain-like tended to obscure the most basic features of the perivascular pump. Here a bare-bones, “simplissimo” model of the perivascular pump is presented. It highlights only the most essential features of the pump mechanism. It also reveals components of brain anatomy and physiology that are not …

A Robust Stepwise Clustering Approach To Detect Individual Trees In Temperate Hardwood Plantations Using Airborne Lidar Data, Gang Shao, Songlin Fei, Guofan Shao

Purdue University Libraries Open Access Publishing Fund

Precise tree inventory plays a critical role in sustainable forest planting, restoration, and management. LiDAR-based individual tree detection algorithms often focus on finding individual treetops to discern tree positions. However, deliquescent tree forms (broad, flattened crowns) in deciduous forests can make these algorithms ineffective. In this study, we propose a stepwise tree detection approach, by first identifying individual trees using horizontal point density and then analyzing their vertical structure profiles. We first project LiDAR data onto a 2D horizontal plane and apply mean shift clustering to generate candidate tree clusters. Next, we apply a series of structure analyses on the …

A New Paradigm Of Reliable Sensing With Field-Deployed Electrochemical Sensors Integrating Data Redundancy And Source Credibility, Ajanta Saha, Sotoudeh Sedaghat, Sarath Gopalakrishnan, Jose Waimin, Aiganym Yermembetova, Nicholas Glassmaker, Charilaos Mousoulis, Ali Shakouri, Alexander Wei, Rahim Rahimi, Muhammad A. Alam

Department of Chemistry Faculty Publications

For a continuous healthcare or environmental monitoring system, it is essential to reliably sense the analyte concentration reported by electrochemical sensors. However, environmental perturbation, sensor drift, and power-constraint make reliable sensing with wearable and implantable sensors difficult. While most studies focus on improving sensor stability and precision by increasing the system’s complexity and cost, we aim to address this challenge using low-cost sensors. To obtain the desired accuracy from low-cost sensors, we borrow two fundamental concepts from communication theory and computer science. First, inspired by reliable data transmission over a noisy communication channel by incorporating redundancy, we propose to measure …

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 …

Non-Polar Ether-Based Electrolyte Solutions For Stable High-Voltage Non-Aqueous Lithium Metal Batteries, Zheng Li, Harsha Rao, Rasha Atwi, Bhuvaneswari M. Sivakumar, Bharat Gwalani, Scott Gray, Kee Sung Han, Thomas A. Everett, Tanvi A. Ajantiwalay, Vijayakumar Murugesan, Nav Nidhi Rajput, Vilas G. Pol

Purdue University Libraries Open Access Publishing Fund

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 …

Form Cdc14 Phosphatase Contributes To Cell Wall Integrity And Pathogenesis In Candida Albicans, Kedric L. Milholland, Ahmed Abdelkhalek, Kortany M. Baker, Smriti Hoda, Andrew G. Demarco, Noelle H. Naughton, Angela N. Koeberlein, Gabrielle R. Lorenz, Kartikan Anandasothy, Antonio Esperilla-Muñoz, Sanjeev K K. Narayanan, Jaime Correa-Bordes, Scott D. Briggs, Mark C. Hall

Purdue University Libraries Open Access Publishing Fund

The Cdc14 phosphatase family is highly conserved in fungi. In Saccharomyces cerevisiae, Cdc14 is essential for down-regulation of cyclin-dependent kinase activity at mitotic exit. However, this essential function is not broadly conserved and requires only a small fraction of normal Cdc14 activity. Here, we identified an invariant motif in the disordered C-terminal tail of fungal Cdc14 enzymes that is required for full enzyme activity. Mutation of this motif reduced Cdc14 catalytic rate and provided a tool for studying the biological significance of high Cdc14 activity. A S. cerevisiae strain expressing the reduced-activity hypomorphic mutant allele (cdc14hm ) as the …

Combating The Hydra: Violence And Resistance In The Habsburg Empire, 1500–1900, Stephan Steiner

Central European Studies

Combating the Hydra explores structural as well as occasion-specific state violence committed by the early modern Habsburg Empire. The book depicts and analyzes attacks on marginalized people “maladjusted” of all sorts, women “of ill repute,” “heretic” Protestants, and “Gypsies.” Previously uncharted archival records reveal the use of arbitrary imprisonment, coerced labor, and deportation. The case studies presented provide insights into the origins of modern state power from varied techniques of population control, but are also an investigation of resistance against oppression, persecution, and life-threatening assaults. The spectrum of fights against debasement is a touching attestation of the humanity of the …

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 …

Incentive Mechanisms To Exploit Intraseasonal Price Arbitrage Opportunities For Smallholder Farmers: Experimental Evidence From Malawi, Tabitha Nindi, Jacob Ricker-Gilbert, Jonathan Bauchet

Department of Agricultural Economics Faculty Publications

Seasonal commodity price fluctuations can potentially offer farmers arbitrage opportunities to increase their income. However, smallholder farmers in most of sub-Saharan Africa often do not exploit these opportunities to the fullest extent possible. To inform this issue, we conducted a randomized controlled trial among 1739 smallholder farmers in Malawi to estimate the impact of two key post-harvest constraints, lack of appropriate storage technology and commitment issues, on farmers' legume storage and sales decisions. The treated groups received (i) an improved storage technology in the form of two hermetic (airtight) bags, (ii) the same improved storage technology under the condition that …

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 …

Measuring Religiosity Of East Asians: Multiple Religious Belonging, Believing, And Practicing, Fenggang Yang, Brian Mcphail

Department of Sociology Faculty Publications

Social surveys normally assume that respondents adhere to a single religious faith in belonging, believing, and practicing congruently. Some surveys even take religious identity as the singular measure of religiosity and examine its relationship with other variables. This practice, however, fails to capture nonexclusive and hybrid religiosity, which is arguably the traditional and normal pattern in East Asia while becoming increasingly common in the West. We have developed a new set of survey questions and conducted a survey among East Asian international students at an American university. The findings show that multiple religious belonging, believing, and practicing are quite common, …
