Hands-On for Whom?
Get PDFHands-on technology-enhanced pedagogies have been hailed as a panacea for engaging K–12 students in engineering. We unpack how the entanglement of the sociopolitical with the educational, namely how factors pertaining to resources and individual characteristics, impact engagement with such pedagogies. In particular, we expand upon how school funding, teacher preparation and support, access to out-of- school resources, and family background impact the in-and out-of- school resources students have access to. Further, we explain how characteristics such as a sense of belonging, pedagogical approaches, and assumptions and gatekeeping by adults impact students’ ability to engage with hands-on engineering education. In doing so, we make a case for rethinking hands-on and technology-enhanced engineering learning for just and inclusive education
Radiation-tolerant thin-film reference electrodes and potentiometric sensors
No full textThe integration of electronic sensors into single-use systems for bioprocessing is challenged by their sensitivity to sterilizing γ-irradiation. This challenge also applies to reference electrodes (REs), whose potentials may be destabilized upon ionization and drift over time. Here we evaluate the performance of thin-film Ag/AgCl REs over a two-month window following γ-ray sterilization using a 60Co source. γ-REs display a characteristic voltage decay function ascribed to the dissipation of radiation-induced charge defects, and exhibit long-term potentiometric stability when stored in phosphate-buffered saline (PBS) with a 95% confidence interval of 4 mV over 60 days. γ-REs have a mean insensitivity (inertness) of 0.6 mV/decade in pH buffers (4.5– 9.0) and/decade in the presence of organic solutes and ions at physiological ionic strength. γ-REs paired with thin-film working electrodes (WE) form sensors with near-Nernstian sensitivity, and irradiation of a thin-film pH sensor (γ-pH/WE plus γ-RE) produces a logarithmic voltage decay that is readily corrected by a single-point calibration function. The γ-irradiated sensor can monitor pH changes in sterile cell culture media over a 3-week period and produces readouts with a mean deviation below 0.04 pH units relative to a commercial meter (ground truth)
Santé, intimité, et identité dans la bande dessinée autobiographique de tradition franco-belge
No full textSanté, intimité, et identité dans la bande dessinée autobiographique de tradition franco-belge examines the ways different autobiographical comic books explore the theme of health, and its influence on identity construction. How do artists represent abstract feelings of pain? How do illnesses influence our sense of self? What is the role of others in our personal history? Our state of health, both physical and mental, has a profound effect on our identity, and how we perceive and tell stories about this dimension of our lives is crucial to forming a sense of self, particularly in a contemporary digitalized world that is now flooded with information and images once considered too private for public consumption. All the works studied exhibit a constant tension between the anxieties of revealing intimacy and vulnerability, and the desire to make suffering meaningful, which is a fundamental aspect of these authors’ quest to recover and to reconstitute a sense of self. Informed by the insights of intimacy studies, psychoanalysis, comics studies, and visual studies, this book shows how these works participate in the process of meaning-making, and how the comics genre allows them to do so in particularly inventive and contemporary ways.
Le livre Santé, intimité, et identité dans la bande dessinée autobiographique de tradition franco-belge examine les différentes manières dont les bandes dessinées autobiographiques explorent le thème de la santé, et son influence sur la construction identitaire. Comment les artistes représentent-ils le sentiment abstrait de la douleur ? Comment la maladie influence-t-elle l’image que nous avons de nous-mêmes ? Quel est le rôle de l’autre dans notre histoire personnelle ? Notre état de santé, à la fois physique et mental, a un effet profond sur notre sens de l’identité, et la façon dont nous nous percevons et racontons des histoires sur cette dimension de nous-mêmes est cruciale à la formation du moi, particulièrement dans un monde qui est de nos jours inondé avec d’informations et d’images autrefois considérées trop privées pour être partagées publiquement. Toutes les œuvres étudiées dans ce livre montrent une tension constante entre les anxiétés de révéler son intimité et sa vulnérabilité, et le désir de trouver un sens à la souffrance endurée, qui est un aspect fondamental dans la quête des auteurs de se retrouver. Basé sur les théories des études sur la littérature intime, de la psychanalyse, et des études sur les bandes dessinées et l’art visuel, ce livre analyse la manière dont ces œuvres participent au processus de fabrication du sens, et comment la bande dessinée leur permet de réaliser cela de façon particulièrement inventive et contemporaine.https://docs.lib.purdue.edu/psrl/1012/thumbnail.jp
Full-Scale Dynamic Wireless Power Transfer and Pilot Project Implementation
Get PDFConsidering the challenges hindering the widespread adoption of electric vehicles (EVs) and heavy-duty electric vehicles(HDEVs), the integration of dynamic wireless power transfer (DWPT) technology into roadways has gained interest. By embedding DWPT components into pavement, electrical power can be delivered to an EV or HDEV as they are in motion. Yet, large-scale implementation depends on further in-depth research, both to explore optimal construction methods and to understand the impact of embedment on the pavement’s resultant behavior. The objective of this project was trifold: (1) design and evaluate a transmitter-receiver topology for DWPT, (2) enhance the understanding of the interaction between the pavement and the embedded DWPT system, and (3) support the design and installation of a 230 kW DWPT system pilot for HDEVs on an existing INDOT roadway. A three-phase transmitter-receiver topology for DWPT was developed and validated, enabling the transmission of power across a wide range of vehicle classes while reducing the power oscillation that has been encountered in existing single-phase designs. To empirically evaluate the impact of DWPT on pavement, two pavement sections—one flexible and one rigid, were designed and constructed at an Accelerated Pavement Test (APT) facility. Following validation of the DWPT design through structural, thermal, and electromagnetic testing, Purdue University developed plans to establish a Dynamic Wireless Power Transfer Testbed (DWPTT) along ¼-mile of US-231 near West Lafayette. This testbed will serve as a critical platform for the transition of DWPT technology from APT sections to a practical roadway environment
A Strategic Alliance: Collaborating with Business Faculty for Information Literacy
No full textInformation literacy is essential for success in a business degree program and in any future career. Business librarians play a pivotal role in helping students learn to locate and ethically use high-quality data from reliable sources. By collaborating with business professors and engaging in classroom activities, librarians effectively connect students with crucial library resources, teaching them how to select and utilize the best tools.
I will highlight a successful partnership with business faculty who identified a skills gap and sought to introduce information literacy early in the undergraduate curriculum. Through over a decade of building relationships, we seized the opportunity to develop two modules in a mandatory undergraduate course, Introduction to Business. These modules teach students how to cite sources and effectively navigate databases and other search tools to find top-tier business information
Engaging China: Beckett’s Debt to Pound, Giles, and Laloy
Get PDFIn her article Engaging China: Beckett’s Debt to Pound, Giles, and Laloy, Lidan Lin examines Ezra Pound’s influence on Samuel Beckett. In their dealings with China, Pound and Beckett are both indebted to such sinologists and cultural transmitters as Ernest Fenollosa, H. A. Giles, Louis Laloy, and Laurence Binyon who introduced Chinese culture, literature, and arts to the Western world through translation and their writings about China. Lin situates the Pound-Beckett connection in the broad cultural context of the early 20th century. She argues that while modernism’s turn to China as a cultural paradigm was collectively brought about by writers, museum curators, and publishers, Beckett’s appropriation of China was part of this paradigm. In mapping this paradigm, she traces it to the 18th- and 19th-century phenomena of Chinoiserie and suggest their cultural and aesthetic continuity
Community College Writing Center Visitation and Outcomes: A RAD Approach to Assessing Writing Center Use and Student Success
Get PDFAs institutions cope with the difficult task of managing scarce resources to support student learning, college writing centers, like other student services, need to be able to articulate and, at times, quantify the benefits they offer the populations they serve. This study examined outcomes associated with visiting the writing center at one American community college in a southern town. Using binary logistic regression, the researchers compared the effects of writing center visitation on the probability of passing and/or earning an A for students enrolled in introductory English and psychology courses, while accounting for other student-level covariates including prior GPA, SES, and minority status. Results indicated that writing center visitors were significantly more likely to pass their English courses and were more likely to earn As in both subjects. Further, the level of visitation was a significant predictor of student outcomes, particularly in English courses, with students who visited the most frequently experiencing a significantly increased likelihood of both passing and earning As. Overall, these results suggested that writing center visitation was meaningfully associated with students’ success in these courses at this institution, after accounting for additional individual-level variables commonly identified as predictors of educational outcomes
Revisiting Articulation: An Approach to Listening and Thinking about Context in the Writing Center
Get PDFThis article offers articulation theory as a tool for listening and thinking about the culture in and around writing centers. After defining a method of articulation analysis that considers articulation, disarticulation, and rearticulation, as well as alignments, contradictions, and tensions within a context, the article performs an articulation analysis on contemporary writing center work. The analysis considers the writing center’s relationship to democracy, multiculturalism, neoliberalism, ethics, and social justice, as shaped by the Great Depression, the Vietnam War, and the 2008 financial crisis. The article concludes with a reflection on the results of the analysis and interventions that may open possibilities for systemic change, including approaches to communal justicing, modeling workplace culture, and training tutors in articulation analysis
