Aporias, Transcendence and a Curriculum of Hospitality

Engaging in dynamic encounters with the other and otherness in education—an issue of creating an aperture that welcomes “a newcomer” either as a new idea or new practice—is important for the field of curriculum studies. Complicating aporias as “various forms of other and otherness,” this paper focuses on the encounters with other and otherness (as our understanding of transcendence or border crossing), in which transcendence (border crossing) becomes possible when a curriculum of hospitality is enacted. While culturally and historically informed, the curriculum of hospitality stresses the simultaneity of (1) ethical attentiveness to the encounters with other and otherness, (2) understanding the premise on which hospitality can be enacted—equality and humility and (3) autobiography as possible enacted form of the curriculum. As a curriculum counterpart (Pinar, 2011), curriculum of hospitality centralizes ethical attentiveness to encounters with other and otherness that makes transcendence (space carving) possible, the possible enactment of which is autobiography. It emphasizes the responsibility of educators for welcoming students into a particular world of ideas, knowledge, and skills that honors otherness with hospitality

Introduction to Confronting Teacher Preparation Epistemicide: Art, Poetry, and Teacher Resistance

In this special issue, we present different perspectives from a documentary project on curricular epistemicide. We view curriculum epistemicide —the annihilation of curriculum—as an embodied process. It limits ways of knowing, questioning, and envisioning the world, and it constricts multiplicity and erases identity and culture. Authors within this volume responded to two requests: 1) they examined some form of epistemicide; and 2) they did not reinforce current systems of power and inequity. Throughout the issue, poetry and photography weave through theoretical papers and empirical studies. A range of methodologies are considered within the articles

Reviving Knowledges through Play and Resistance: The Case of Navajo Conceptions of Space

The authors explore a possible cause of epistemicidal predispositions of the dominant Eurocentric curricula. They posit that one way to determine a plausible contributing factor of this increasing devastation is to consider epistemicide through the lens of intellectual development. To do this, the authors examine parallel patterns of behavior in the domains of developmental and cognitive psychology. The authors then discuss an alternative framework to the Western conception of space within formal K-12 education by presenting the Navajo conception of space and play. Throughout the paper, the authors argue that all students—and especially those living in poverty in commercially constructed, large urban areas—deserve, and need, an educational framework that expands rather than constricts their schema of space and facilitates their agency to renew and regenerate their environment

Adolescents\u27 Digital Literacies in Flux: Intersections of Voice, Empowerment, and Practices

This article features a collaborative autoethnographic examination of three adolescent-researchers’ digital literacies. The participatory design punctuates the role of the adolescent-researchers as they explored their meaning-making practices. Such collaborative research, which included three adolescents and their parents, not only resurfaces parent-inquiry, but also brings the adolescent-researcher voice to the forefront of literacy research. Two research questions guided the investigation: (a) What do adolescent-researchers tell us about their digital and nondigital literacy practices? and (b) In what ways do adolescent-researchers’ retrospective examinations of their own practices reveal their perspectives of these practices and the power (and power struggles) that underlie them? The research team engaged in two rounds of coding, embracing first dramaturgical coding and then versus coding. Results suggested that Perspective/Attitude was the most prevalent attribute in the adolescent-researchers’ discourse. Moreover, versus coding revealed strong relationships between “then versus now.” Overall, the voices of the adolescent-researchers offer ongoing authenticity to discussions of their practices, creating continued opportunities to rethink the implications and applications of digital and nondigital practices in adolescents’ lives

A multi-systems approach to human movement after ACL reconstruction: the musculoskeletal system

Several negative adaptations to the musculoskeletal system occur following anterior cruciate ligament (ACL) injury and ACL reconstruction (ACLR) such as arthrogenic muscle inhibition, decreased lower extremity muscle size, strength, power, as well as alterations to bone and cartilage. These changes have been associated with worse functional outcomes, altered biomechanics, and increased risk for re-injury and post-traumatic osteoarthritis. After ACL injury and subsequent ACLR, examination and evaluation of the musculoskeletal system is paramount to guiding clinical decision making during the rehabilitation and the return to sport process. The lack of access many clinicians have to devices necessary for gold standard assessment of muscle capacities and force profiles is often perceived as a significant barrier to best practices. Fortunately, testing for deficits can be accomplished with methods available to the clinician without access to costly equipment or time-intensive procedures. Interventions to address musculoskeletal system deficits can be implemented with a periodized program. This allows for restoration of physical capacities by adequately developing and emphasizing physical qualities beginning with mobility and movement, and progressing to work capacity and neuromuscular re-education, strength, explosive strength, and elastic or reactive strength. Additional considerations to aid in addressing strength deficits will be discussed such as neuromuscular electrical stimulation, volume and intensity, eccentric training, training to failure, cross-education, and biomechanical considerations. The American Physical Therapy Association adopted a new vision statement in 2013 which supported further development of the profession's identity by promoting the movement system, yet validation of the movement system has remained a challenge. Application of a multi-physiologic systems approach may offer a unique understanding of the musculoskeletal system and its integration with other body systems after ACLR. The purpose of this clinical commentary is to highlight important musculoskeletal system considerations within a multi-physiologic system approach to human movement following ACLR.

Chemical Doppelgangers in GALAH DR3: the Distinguishing Power of Neutron-Capture Elements Among Milky Way Disk Stars

The observed chemical diversity of Milky Way stars places important constraints on Galactic chemical evolution and the mixing processes that operate within the interstellar medium. Recent works have found that the chemical diversity of disk stars is low. For example, the APOGEE "chemical doppelganger rate," or the rate at which random pairs of field stars appear as chemically similar as stars born together, is high, and the chemical distributions of APOGEE stars in some Galactic populations are well-described by two-dimensional models. However, limited attention has been paid to the heavy elements (Z > 30) in this context. In this work, we probe the potential for neutron-capture elements to enhance the chemical diversity of stars by determining their effect on the chemical doppelganger rate. We measure the doppelganger rate in GALAH DR3, with abundances rederived using The Cannon, and find that considering the neutron-capture elements decreases the doppelganger rate from 2.2% to 0.4%, nearly a factor of 6, for stars with -0.1 < [Fe/H] < 0.1. While chemical similarity correlates with similarity in age and dynamics, including neutron-capture elements does not appear to select stars that are more similar in these characteristics. Our results highlight that the neutron-capture elements contain information that is distinct from that of the lighter elements and thus add at least one dimension to Milky Way abundance space. This work illustrates the importance of considering the neutron-capture elements when chemically characterizing stars and motivates ongoing work to improve their atomic data and measurements in spectroscopic surveys.Comment: 23 pages, 16 figures, 1 table.

APOGEE Kinematics I: Overview of the Kinematics of the Galactic Bulge as Mapped by APOGEE

We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky Way. APOGEE includes extensive coverage of the stellar populations of the bulge along the mid-plane and near-plane regions. From these data, we have produced kinematic maps of 10,000 stars across longitudes 0 deg < l < 65 deg, and primarily across latitudes of |b| < 5 deg in the bulge region. The APOGEE data reveal that the bulge is cylindrically rotating across all latitudes and is kinematically hottest at the very centre of the bulge, with the smallest gradients in both kinematic and chemical space inside the inner-most region (l,|b|) < (5,5) deg. The results from APOGEE show good agreement with data from other surveys at higher latitudes and a remarkable similarity to the rotation and dispersion maps of barred galaxies viewed edge on. The thin bar that is reported to be present in the inner disk within a narrow latitude range of |b| < 2 deg appears to have a corresponding signature in [Fe/H] and [alpha/Fe]. Stars with [Fe/H] > -0.5 have dispersion and rotation profiles that are similar to that of N-body models of boxy/peanut bulges. There is a smooth kinematic transition from the thin bar and boxy bulge (l,|b|) < (15,12) deg out into the disk for stars with [Fe/H] > -1.0, and the chemodynamics across (l,b) suggests the stars in the inner Galaxy with [Fe/H] > -1.0 have an origin in the disk.Comment: Accepted by ApJ 15 December 201
