• Do I have to have a librarian come to my class? Power imbalances and power moves in library instruction

      Arteaga, Roberto; Moeller, Christine M. (The University of Arizona, 2020-09-08)
      The question, “Do I have to have a librarian come to my class,” may be familiar to academic teaching librarians. At first, this question may be frustrating in multiple ways, but a thorough examination of the context behind the question can help identify the root and the broader implications of such questions. These types of questions highlight the structures that impact library instruction and reveal the ways in which power imbalances affect the work and mission of teaching librarians. In this interactive presentation, attendees will engage in a series of activities and discussions centered around the structures and power imbalances that are deeply embedded within higher education. Participants will dissect, analyze, and interpret questions and situations familiar to teaching librarians in order to begin formulating pedagogically meaningful responses. Through this exploration, participants will be able to identify the root of power imbalances and determine ways to foster change.
    • Assessment Is Constructed and Contextual: A Faculty-Librarian Pilot to Explore Critical Approaches to Curriculum & Assessment

      Branch, Nicole; Pfeiffer, Loring; Voss, Julia; Santa Clara University (The University of Arizona, 2020-09-16)
      Students of color and marginalized-identifying students have more sophisticated critical information literacy skills across all dimensions compared to the comparison groups, reflecting greater cumulative awareness of: Journalistic/editorial best practices, Author expertise, Type of work (genre), Source research/evidence, Methods, Local sourcing, Diverse voices. Looking at specific dimensions of information literacy, Students of color and students who approach the research task as an opportunity to defend their own culture more frequently described the importance of including local voices in news reporting, compared to the comparison groups. Students of color and marginalized-identifying students more frequently critically evaluated the research/evidence of their sources than the comparison groups. Maginalized-identifying students more frequently considered authors' expertise when evaluating sources than mainstream-identifying students. Key Findings: 1. Students who self-identify as marginalized are better at critically assessing information than students who do not. Many approaches to assessment of student learning, even those that seek to operationalize critical approaches and an equity framework, persist in centering the deficiencies of marginalized students as a starting point, seeking to bring these learners “up” to what is perceived as “normative.” This finding reveals that marginalized students can also be the standard-bearers. 2. Interviews can be sites of meaning-making. Alternative assessment methods (in this case, interviews and grounded-theory methodologies) provide opportunities for educators and students to mutually engage in revealing assets of learners and meaning making that can help us (students and instructors) extend beyond/breakthrough academic conditioning. 3. Interviews offer opportunities for asset-based, anti-racist assessment. Alternative assessment methodologies may have particularly powerful implications for the development of learning outcomes that center the assets of students who are under-represented in the academy. The theme of “defending own culture” can be extrapolated to information literacy skills such as: Recognizing bias, Invoking one’s power as a producer of information, Countering stereotypical narratives.
    • An Appeal to Kairos: Building a Sustainable Assessment Practice

      García, Sheila; Grand Valley State University (The University of Arizona, 2020-09-14)
      Perhaps one of the most common narratives among librarians is the difficulty of saying "no" and scoping our work appropriately. Fobazi Ettarh's work on "Vocational Awe" examined the roots of this problem critically and has spurred continued discussion around dismantling the framing of the library profession as a "calling" and valuing individual well-being. This approach to the issue of burnout and the glorifying of unsustainable practices can be particularly impactful within Social Justice work and more so, for traditionally underrepresented communities. This session will focus on an individual journey to build a sustainable assessment practice that centers the needs of an underserved community. To break the cycle of assessment practices solely benefitting academic discourse, the concept of Kairos - the "right" and/or opportune time do something - should guide practice to ensure intentional sustainability of our work. This lightning talk will walk through the journey of a Diversity Alliance resident librarian and her initial capstone project that focused on the experience of undergraduate language brokers in academia in order to inform first-year information literacy instruction. Recognizing that a short-term position would almost guarantee that results of research do not directly benefit the community that is studied, the research practice was reframed accordingly to a multi-year collaborative project. Participants will leave the session with a deeper understanding of the use of Kairos to reframe their practice, moving toward critical practice and intentional sustainability of assessment practice. Additionally, this talk will highlight an area of need within librarianship that has not been discussed as deeply, which is the need to ensure that results of library assessment, particularly assessment that uses a social justice lens, not only benefits but is communicated back to the populations that are directly affected, an approach that necessitates a sustainable research practice.
    • Support beyond the studio: Critical pedagogy in art librarianship

      Jennings, Michele; Hunt, Courtney; Ohio University; The Ohio State University (The University of Arizona, 2020-09)
      This session grew out of conversations between two art librarians working in close proximity at different institutions, centered around the idea that while the needs for art and design students require a different type of academic support than others (Hemmig, 2009), this approach to learning and information lends itself to critical pedagogy and takeaways for other disciplines. Dismantling the paradigm that positions librarians in the role of the sage, critical pedagogy establishes more of a horizontal line of support from the student to the librarian. Those students whose academic work is rooted in creative practice operate on a continuum that does not culminate in a single research paper or study. Instead, they may work on a piece in their first year and continue to iterate until their thesis show. Therefore, it is critical to consider how we teach and support students that we work with holistically. Art and design students especially “need to learn how to find their voices, which in turn becomes liberating, allowing them to fully engage in their own intellectual and educational process” (Reale, 2012, p. 85). This session explores strategies for supporting students working in creative disciplines for the entirety of their academic stay and beyond, and what takeaways there may be for librarians working in other areas. For example, Grimm and Meeks (2017) address critlib and social justice in visual literacy—how library practitioners may address inequity and racism in representation, teaching students to look (and make) critically. While visual literacy naturally lends itself to art and design library users, it is equally vital that students in other areas gain the skills necessary to grapple with and decode the visual media that surrounds them inside and outside of the classroom. Centering the idea of holistic student support, these two librarians began to think about what it means to apply critical pedagogy to art librarianship. Studio art and design pedagogy align with the tactics and motivations of critical librarianship and pedagogy; by attempting to recreate the studio environment through activities emphasizing collaboration and critique, this session will demonstrate how librarians can critically engage with students in the long term in any discipline.

    • Extensions for Everyone: Syllabus Policies that Center Accessibility

      Wong, Melissa; University of Illinois at Urbana-Champaign (The University of Arizona, 2020-09-14)
      Instructors who embrace critical pedagogy work to create inclusive learning environments and dismantle barriers to education. Ironically, one such barrier can be the formal accommodations process that was created to ensure equitable access for student with disabilities (only a fraction of students with disabilities request needed accommodations). In order to better serve students with disabilities, many instructors have adopted Universal Design for Learning (UDL) and a proactive approach to accessible course design. Instructors implementing UDL often focus on the accessibility of course materials and using varied and inclusive pedagogical strategies. However, instructors may overlook the central role course policies play in accessibility. In fact, many common accommodations are a direct response to instructor policies. For example, instructors may be asked to grant an extension for a due date if a student experiences exacerbation of a chronic illness; however, this accommodation only exists as a standard accommodation because of instructors’ often inflexible policies around attendance and deadlines. In this talk, I identify course policies that create barriers for students with disabilities and show how instructors can adopt more flexible course policies that support inclusion and student success while decreasing the need for formal accommodations.

    • The library is not a restaurant: Reference appointments and neoliberal language

      Gardner, Carolyn Caffrey; Clarke, Maggie; California State University, Dominguez Hills (The University of Arizona, 2020-09-04)
      This presentation will detail research on “no-show” student research appointments with an eye towards how libraries can mitigate student perceptions of appointments as commercial transactions which have been reinforced by problematic language borrowed from other sectors (hospitality, medical). We will share survey results from a range of higher education institutions regarding their current attitudes and practices towards no-show appointments. We will present strategies we’ve used to encourage appointment attendance by fostering a sense of shared community of learners rather than using shame, financial penalty, or other punitive action to decrease no-shows. Finally, we’ll hear from students on their perceptions of taking up space in research appointments and analyze how research appointment practices can reward students who already have privilege. Participants will critically reflect on their own experiences and practices with research appointments through guided reflection and small group discussion in order to empower students.
    • Reimagining Peer Review

      Ford, Emily; Portland State University (The University of Arizona, 2020-09)
      As you may recall, the 2020 Critical Library and Pedagogy Symposium instituted an open peer review process—not masking submitters’ names and other identifying information—to review proposed sessions. This decision came after the committee noted a lack of diversity in accepted sessions using a closed review process. Using open peer review allowed the committee to balance accepted proposals and offer a diverse range of views and experiences among presenters. This hour-long facilitated discussion will examine bias and power structures inherent in peer review. It will be an interactive session that allows participants to critically examine their views and previous experiences with peer review, and begin to reimagine it. What can opening peer review do to create more equitable scholarly spaces? What problems does opening peer review improve, and what new challenges does it present? Note that this session will be interactive, and will use the Zoom breakout room feature as well as Google Docs for collaboration.
    • Beyond Self-Care and Standardization: Creating a Sustainable Teaching Practice through Engaged Pedagogy

      Arellano Douglas, Veronica; Deal, Emily; Hernandez, Carolina; University of Houston (The University of Arizona, 2020-09-16)
      Conversations around sustainable teaching practices either focus on self-care, placing responsibility for well-being on librarians; or program efficiency, which creates work environments that create business-like models for standardization of teaching programs. This framing of sustainability is reactive and harmful -- we are working within existing power structures and dynamics rather than imagining ways to share power and create space for engaged pedagogy. bell hooks introduces the concept of engaged pedagogy as a model of education that “does not seek to simply empower students… [but] will also be a place where teachers grow and are empowered by the [learning] process” (p. 21). It’s a feminist expansion of critical pedagogy that takes into account the personhood of the teacher as well as the student, creating a co-learning environment rooted in mutual respect where intellectual and personal development can flourish. This discussion session moves beyond typical sustainability conversations to develop ideas for positive change in library teaching programs with the goal of creating generative, healthy work practices

    • The Good, The Bad, and The Non-Circular Signals

      Bose, Tamal; Tsang, Stephanie D.; Samuel, Al; Univ Arizona, Dept Electrical and Computer Engineering (International Foundation for Telemetering, 2019-10)
      Second-order (SO) non-circularity is a statistical property that is used to classify signals. Signals with SO non-circularity are extensively used in communication and radar systems. The SO non-circularity property is generally useful in the application of array processing techniques for extending antenna apertures. Exploiting this non-circularity property for a multi-faceted set of communication-type and radar-type signals is the objective of this study. For a given type of signal, the circularity quotient and its properties are tested and evaluated in terms of parameters such as the modulus of its phase, complex covariance, pseudo-variance, the angle orientation of the ellipse, its eccentricity, and other relevant properties are calculated. A geometrical interpretation for the circularity quotient and the correlation coeficient is used to derive the bounds for circularity.
    • DOPPLER POWER SPECTRA FROM VEHICLE-TO-EVERYTHING PROPAGATION EXPERIMENTS

      Rice, Michael; Harrison, Willie K.; Norman, Kalin; Jensen, Benjamin; Brigham Young University, Dept Electrical and Computer Engineering (International Foundation for Telemetering, 2019-10)
      This paper presents the results of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) propagation experiments. The experimental results are summarized by Doppler power spectra. Our measurements indicate the need for a dynamic system that can handle the variable channels experienced in vehicle-to-everything communications.
    • JFLUTTER REAL TIME FLUTTER ANALYSIS IN FLIGHT TEST

      Rubio, Pedro; Coll, Francisca; AIRBUS DEFENCE & SPACE Flight Test (International Foundation for Telemetering, 2019-10)
      During the development of an aircraft it is mandatory to demonstrate that the aircraft is free from flutter within its operational flight envelope. This piece showcases JFlutter, a flutter analysis tool developed within Airbus Defence & Space Flight Test Analysis Tools. JFlutter allows the analysis of this phenomenon in real time monitoring and post flight mode. Using the FxS dataserver as data provider, a reliable data gathering mechanism has been used for this critical tool. As flutter means aero elastic instability, potentially dangerous, flight safety becomes a main requirement. For safety reasons and in order to reduce overall test program duration it is necessary to check predicted frequencies and damping in real time / monitoring.
    • HIGH-PERFORMANCE EXTENSIBLE SOQPSK (E-SOQPSK) MODULATION WAVEFORMS FOR AERONAUTICAL MOBILE TELEMETRY COMMUNICATIONS

      Lu, Cheng Y.; Argula, Rajeev; Sasvari, Gyorgy; Cook, Paul; Teletronics a Curtiss-Wright Company (International Foundation for Telemetering, 2019-10)
      To utilize the resilience to multipath and rapidly varying Doppler shifts offered by a multicarrier (MC) Orthogonal Frequency Division Multiplexed (OFDM) modulation waveform, and the high transmitter power efficiency offered by a single carrier (SC) Shaped Offset Quadrature Phase Shift Keying (SOQPSK) modulation waveform, we propose a novel Extensible Shaped Offset Quadrature Phase Shift Keying (E-SOQPSK) modulation waveform. E-SOQPSK is an OFDM structured single carrier modulation waveform, configurable to include OQPSK, SOQPSK, or mQAM. Preliminary laboratory results confirmed its low Peak-to-Average Power ratio (PAPR) and high spectrum efficiency. Preliminary simulations demonstrated multipath resilience of ESOQPSK waveform by utilizing OFDM structure based Frequency-Domain equalization at receiver.
    • APSK SYMBOL TIMING AND CARRIER PHASE SYNCHRONIZATION ON AN FPGA IN A C-BAND TELEMETRY RECEIVER

      Perrins, Erik; Baxter, Jason; Univ Kansas, Dept Electrical Engineering and Computer Science (International Foundation for Telemetering, 2019-10)
      This paper presents the implementation of a standard PLL-based timing and phase synchronization system on hardware usingan FPGA. The synchronization system is shown to successfully recover a 16-APSK signal despite off sets in phase and frequency between the transmitter and receiver local oscillators. Furthermore, it is shown that system performance, in terms of symbol times required to achieve lock, is comparable to double-precision floating point simulations despite using fixed point numbers with as few as 5 fractional bits for most computations.
    • Intelligent Monitoring Technology of Flight Test Based on Automatic Identification of Test Points

      Shenghu, Liu; Zhe, Yang; Bing, Ye; Chinese Flight Test Establishment (International Foundation for Telemetering, 2019-10)
      As the smallest component unit of the flight test task, test point defines the tasks and requirements to be completed by the test aircraft, which is the main basis for the flight effect evaluation. This article through in-depth analysis parameters variation characteristics of the testing aircraft in different test points, combined with the prior knowledge that the domain experts artificial recognize test points, extraction the key parameters of influencing test point identification, and their change rule. We constructed the knowledge base for test point identification, designed test point automatic identification algorithm. Combined with the flight test real-time task evaluation technology, we developed the real-time monitoring system for flight test based on the test point automatic identification and intelligent evaluation. It realized the change from the "intelligent security monitoring" to "intelligent task monitoring", and effectively improve the flight efficiency of the test aircraft.
    • Latest Development Status on the Commercial derivative aircraft Based Instrumentation Telemetry System (CBITS) Program

      Roudebush, J. Kyle; Hernandez, Jose; Kujiraoka, Scott; NAVAIR-Point Mugu; GBL Systems (International Foundation for Telemetering, 2019-10)
      The Commercial derivative aircraft Based Instrumentation Telemetry System (CBITS) project will provide an advanced airborne telemetry system and capability to support the test and evaluation (T&E) of current and future military weapons and defensive systems. In conjunction with the Range Support Aircraft (RSA) contracts, the CBITS project will provide an autonomous airborne T&E asset capable of supporting Major Range and Test Facility Base (MRTFB) government ranges and open-ocean testing worldwide. The project will develop an improved S-Band airborne telemetry (TM) capability and a new L- and C-Band telemetry capability as a result of frequency spectrum selloff issues. These improved telemetry capabilities, along with the existing airborne Flight Termination System/Command Destruct (FTS/CD) capability, existing radar for Range Surveillance (RS) and Range Clearance (RC), and range unique augmenting communication systems will be integrated into a Gulfstream G550 Airborne Early Warning (AEW) RSA which will be replacing the current NP-3D Remote Area Safety Aircraft (RASA). This paper will discuss the latest developmental status of the CBITS project.
    • VALIDATION PROTOCOL - THE MISSING PUZZLE PIECE

      Moskal, Jakub; Whittington, Austin; Morgan, Jon; Kokar, Mitch; Abbott, Ben; VIStology Inc; Southwest Research Institute; Edwards AFB (International Foundation for Telemetering, 2019-10)
      In multi-vendor T&E systems, a single hardware vendor cannot anticipate the dependencies on the settings from hardware manufactured by other vendors, or the systemic constraints that are specific to a particular customer. The T&E community has recognized the fact that MDL and TMATS XML are not sufficient to addresst his problem alone, and that there is a need for a separate, constraints language. Constraints written in such a language can be validated by a third party validation engine, without relying on any particular vendor’s software. To this end, we developed the concept of TACL, a candidate for the standard constraint language, and demonstrated it with a reference implementation of a TACL engine integrated with the iNET System Manager. In this paper, we argue that this integration should be standardized in the form of a Validation Protocol in order to turn the existing system into a loosely-coupled, standards-based architecture.
    • APPLICATIONS OF AUTONOMOUS NAVIGATION IN NEXT-GENERATION MARS ROVERS

      Kosbar, Kurt; Dlouhy, Sarah; Arneson, Ethan; Missouri University of Science and Technology (International Foundation for Telemetering, 2019-10)
      This paper describes a module used to provide autonomous navigation and obstacle avoidance to a teleoperated prototype Mars rover designed to compete in the 2019 University Rover Challenge. For the competition’s Autonomous Traversal task, the rover must be capable of traversing difficult desert terrain in search of visual waypoints. Our design uses a custom Navigation Board (NavBoard), a mobile robotics computer, and a sensor capable of producing a dense point cloud. NavBoard provides quaternion-based orientation data, distance measurements from a 1D LiDAR system, and GPS data over ethernet to a mobile robotics computer. This computer derives a 3D point cloud from a three-headed collinear stereoscopic camera then processes that data along with the data from NavBoard to determine the correct action to navigate through sparsely mapped terrain.
