Digital Fluency For Open Educational Resources: The Active Role Of Libraries In Establishing Oer In Germany's Higher Education Sector, Margaret Plank, Britta Beutnagel

Proceedings of the IATUL Conferences

Free access to education, information and knowledge is a declared educational policy goal that all state universities in Germany strive to achieve. Open Educational Resources (OER) make an important contribution to this, as their use is open to all teaching staff and learners. The development, use and distribution of OER is currently focused by several government funding grants, but still has not fully arrived in the country’s educational practices. Reasons for this include the fact that dealing with OER requires sound knowledge much of which relates to copyright and licensing law. In addition, for the technical design and provision of …

Weaving Open Dialogue Using Canada’S Open Science Roadmap Framework, Heather Cunningham, Christina S.Y. Kim

Proceedings of the IATUL Conferences

Open science (OS) as a movement has transformative potential in making the process of scientific research transparent and collaborative as well as the outputs freely accessible to all in society. However, these opportunities and challenges are subject to biases and entrenched in power disparities. In addition, the very broad nature of open science also invokes challenges in having meaningful discussions. In 2020, the Government of Canada unveiled a national framework, Roadmap to Open Science, which provided overarching principles and recommendations to allow federal science to be open to all. The University of Toronto (U of T) used this national open …

A Qualitative Study Of Emotions Experienced By First-Year Engineering Students During Programming Tasks, Zahra Atiq, Michael C. Loui

School of Engineering Education Faculty Publications

In introductory computer programming courses, students experience a range of emotions. Students often experience anxiety and frustration when they encounter difficulties in writing programs. Continued frustration can discourage students from pursuing engineering and computing careers. Although prior research has shown how emotions affect students’ motivation and learning, little is known about students’ emotions in programming courses. In this qualitative study of first-year engineering students taking an introductory programming course, we examined the emotions that these students experienced during programming tasks and the reasons for experiencing those emotions. Our study was grounded in the control-value theory of achievement emotions. Each research …

A Quantitative Model Of Volume Compensation As A Mechanism For Oscillatory Flow Of Cerebrospinal Fluid, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

Specifying the exact mechanism driving cyclic, oscillatory flows of cerebrospinal fluid (CSF) through the cerebral ventricles and subarachnoid spaces remains an open problem. Here is a new quantitative hypothesis describing how cyclic expansion and contraction of the cerebral blood volume moves CSF within the closed box of the cranium. As whole brain tissue expands with added blood, volume compensation is provided by partial collapse of the superior sagittal and transverse venous sinuses. The magnitude of the expansion and contraction of whole brain tissue volume can be estimated from the changes in intravascular volume, which in turn can be divided into …

Decisions Squared: A Deeper Look At Student Characteristics, Performance, And Writing Center Usage In A Multilingual Liberal Arts Program In Russia, L. Ashley Squires

The Writing Center Journal

This article contributes to the ongoing discussion of student characteristics and usage/nonusage patterns in the writing center. Using a sample of 107 economics students from a selective, bilingual liberal arts program in Russia, the author finds statistically significant relationships among GPA, gender, English-language proficiency, and writing center usage. Namely, writing center usage predicts higher GPA and closes two achievement gaps related to gender and English proficiency. These findings complicate the picture presented by Lori Salem (2016), whose research showed gender, low SAT score, and being an English language learner to be strong predictors of writing center usage and produced a …

Numerical Solutions Of A Gradient-Elastic Kirchhoff Plate Model On Convex And Concave Geometries Using Isogeometric Analysis, Yu Leng, Tianyi Hu, Sthavishtha R. Bhopalam, Hector Gomez

Purdue University Libraries Open Access Publishing Fund

In this work, we study numerical solutions of a gradient-elastic Kirchhoff plate model on convex and concave geometries. For a convex plate, we first show the well-posedness of the model. Then, we split the sixth-order partial differential equation (PDE) into a system of three second-order PDEs. The solution of the resulting system coincides with that of the original PDE. This is verified with convergence studies performed by solving the sixth-order PDE directly (direct method) using isogeometric analysis (IGA) and the system of second-order PDEs (split method) using both IGA and C⁰ finite elements. Next, we …

Copper(I)‒Pyrazolate Complexes As Solid-State Phosphors: Deep- Blue Emission Through A Remote Steric Effect, Yuichiro Watanabe, Benjamin M. Washer, Matthias Zeller, Sergei Savikhin, Lyudmila V. Slipchenko, Alexander Wei

Department of Chemistry Faculty Publications

We describe a novel manifestation of rigidochromic behavior in a series of tetranuclear Cu(I)–pyrazolate (Cu4pz4) macrocycles, with implications for solid-state luminescence at deep-blue wavelengths (<460 nm). The Cu4pz4 emissions are remarkably sensitive to structural effects far from the luminescent core: when 3,5-di-tert-butylpyrazoles are used as bridging ligands, adding a C4 substituent can induce a blue shift of more than 100 nm. X-ray crystal and computational analyses reveal that C4 units influence the conformational behavior of adjacent tert-butyl groups, with a subsequent impact on the global conformation of the Cu4pz4 complex. Emissions are mediated primarily through a cluster-centered triplet (3CC) state; compression of the Cu4 cluster into a nearly close-packed geometry prevents the reorganization of its excited-state structure and preserves the 3CC energy at a high level. The remote steric effect may thus offer alternative strategies toward the design of phosphors with rigid excited-state geometries.

Local Dynamics During Thinning And Rupture Of Liquid Sheets Of Power-Law Fluids, Vishrut Garg, Sumeet S. Thete, Christopher R. Anthony, Osman Basaran

School of Chemical Engineering Faculty Publications

Rupture of liquid sheets of power-law fluids surrounded by a gas is analysed under the competing influences of pressure due to van der Waals attraction, inertia, viscous stress and capillary pressure due to surface tension. Results of a combined theoretical and computational study are presented over the entire range of parameters governing the thinning of a power-law fluid of power-law exponent 00n=1n=1: Newtonian fluid) and Ohnesorge number 0≤Oh0≤Oh<∞0≤OhOh≡μ0/ρh0σ−−−−√Oh≡μ0/ρh0σ, and μ0,ρ,h0" role="presentation" style="box-sizing: border-box; margin: 0px; padding: 0px; border: 0px; font-variant: inherit; font-stretch: inherit; line-height: normal; font-family: inherit; vertical-align: baseline; display: inline-table; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; position: relative;">μ0,ρ,h0μ0,ρ,h0 and σ" role="presentation" style="box-sizing: border-box; margin: 0px; padding: 0px; border: 0px; font-variant: inherit; font-stretch: inherit; line-height: normal; font-family: inherit; vertical-align: baseline; display: inline-table; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; …

An Optimal Sizing Framework For Autonomous Photovoltaic/Hydrokinetic/Hydrogen Energy System Considering Cost, Reliability And Forced Outage Rate Using Horse Herd Optimization, Abdulaziz Alanazi, Mohana Alanazi, Saber Arabi Nowdeh, Almoataz Y. Abdelaziz, Adel El-Shahat

Purdue University Libraries Open Access Publishing Fund

The components outage of an energy system weakens its operation probability, which can affect the sizing of that system. An optimal sizing framework is presented for an autonomous hybrid photovoltaic/hydrokinetic/fuel cell (PV/HKT/FC) system with hydrogen storage to supply an annual load demand with forced outage rate (FOR) of the clean production resources based on real environmental information such as irradiance, temperature, and water flow. The sizing problem is implemented with the objective of cost of energy (COE) minimization and also satisfying probability of load supply (PLS) as a reliability constraint. The FOR effect of the photovoltaic and hydrokinetic resources is …

A Two-Layer Model Explains Higher-Order Feature Selectivity Of V2 Neurons, Timothy D. Oleskiw, Justin D. Lieber, J. Anthony Movshon, Eero P. Simoncelli

MODVIS Workshop

Neurons in cortical area V2 respond selectively to higher-order visual features, such as the quasi-periodic structure of natural texture. However, a functional account of how V2 neurons build selectivity for complex natural image features from their inputs – V1 neurons locally tuned for orientation and spatial frequency – remains elusive.

We made single-unit recordings in area V2 in two fixating rhesus macaques. We presented stimuli composed of multiple superimposed grating patches that localize contrast energy in space, orientation, and scale. V2 activity is modeled via a two-layer linear-nonlinear network, optimized to use a sparse combination of V1-like outputs to account …

Distribution-Oblivious Online Algorithms For Age-Of-Information Penalty Minimization, Cho-Hsin Tsai, Chih-Chun Wang

Department of Electrical and Computer Engineering Technical Reports

The ever-increasing needs of supporting real-time applications have spurred new studies on minimizing Age-of-Information (AoI), a novel metric characterizing the data freshness of the system. This work studies the single-queue information update system and strengthens the seminal results of Sun et al. on the following fronts: (i) When designing the optimal offline schemes with full knowledge of the delay distributions, a new fixed-point-based method is proposed with quadratic convergence rate, an order-of-magnitude improvement over the state-of-the-art; (ii) When the distributional knowledge is unavailable (which is the norm in practice), two new low-complexity online algorithms are proposed, which provably attain the …

One week apart, HST1 vs HST (11.0°C; 50%RH), as a reliability trial and HST3 in 31.0°C; 50%RH were completed. Then 90 min dehydration, STHA (no fluid intake), for 5 consecutive days (39.5^oC; 60%RH), using …

An Empirical Exploration Of Southeast Asian American Residential Patterns In The San Francisco Bay Area (2000–2019), Minh Q. Nguyen

Journal of Southeast Asian American Education and Advancement

This paper explores three methods of reporting residential patterns: (1) concentration profiles, (2) density maps, and (3) proximity profiles. I analyze U.S. Census data to map and evaluate the residential patterns for Southeast Asian Americans in the nine-county San Francisco Bay Area. Drawing from the field of urban planning, I report two measures of segregation and concentration (a) dissimilarity indices and (b) spatial proximity indices, and I discuss their limitations. Since mapping and spatial statistics are essential to understanding the histories, development, and advancement of Southeast Asian American communities, it is important to promote their broad usage. …

Climate Justice In Engineering Education, Tyler J. Morgan, Donna Riley, Caroline M. Camfield

Discovery Undergraduate Interdisciplinary Research Internship

The goal of this research is to design a learning module for Purdue first-year engineering (FYE) students to learn climate fundamentals, and the role of engineers in responding to climate justice challenges. There is a lack of climate material within these classes currently, leading to a lack of climate conscious engineers in the future. The project entailed reviewing and synthesizing a wide variety of previous research on climate change education in engineering, including key learning objectives and their assessment. Because one of the key foci of the first-year engineering sequence relates to data analysis and management, we focused our work …

Crowd-Machine Partnership On Road Infrastructure Quality Recognition And Resilience, Eric J. Thompson

Discovery Undergraduate Interdisciplinary Research Internship

Public roads are a vital component of modern-day society, as they are necessary for the transportation of people and capital; consequently, it is important that they are regularly and effectively maintained. Unfortunately, this maintenance is difficult to manage due to the sheer area that roads span. It is an arduous task to locate every instance of road damage, as well as to determine the urgency that each bit of damage necessitates. Repairing road damage has high costs in labor, time, and money. To provide a more efficient way to monitor road conditions, we are designing a mobile application that collects …

Hhl Algorithm On The Honeywell H1 Quantum Computer, Adrik B. Herbert, Eric A. F. Reinhardt

Discovery Undergraduate Interdisciplinary Research Internship

The quantum algorithm for linear systems of equations (HHL algorithm) provides an efficient tool for finding solutions to systems of functions with a large number of variables and low sensitivity to changes in inputs (i.e. low error rates). For complex problems, such as matrix inversion, HHL requires exponentially less computational time as compared with classical computation methods. HHL can be adapted to current quantum computing systems with limited numbers of qubits (quantum computation bits) but a high reusability rate such as the Honeywell H1 quantum computer. Some methods for improving HHL have been proposed through the combination of quantum and …

A Systems Approach To Studying Online Communities, Jeremy Foote

Purdue University Libraries Open Access Publishing Fund

Much early communication research was inspired by systems theory. This approach emphasizes that individuals and groups use communication to interact with and respond to their larger environment and attempts to outline the ways that dif‐ ferent levels interact with each other (e.g., work groups within departments within firms). Many concepts from systems theory—such as emergence and feedback loops—have become integral parts of communication theories. However, until recently, quantitative researchers have struggled to apply a systems approach. Large‐scale, multilevel trace data from online platforms combined with computational advances are enabling a turn back toward systems‐inspired research. I out‐ line four systems‐based …
