Where image and text meet identity: Gifted studentsâ poetry comics and the crafting of ânerd identitiesâ
This article reports on a study of how a class of fifteen- and sixteen-year-old gifted high school students âmixedâ the media of poetry and comics to unveil and interrogate (what they called) their ânerd identities.â Both co-authors constructed and co-taught a class within a literature-based comics course that led students through various writing processes that focused on the visual and textual properties of poetry and comics. Researchers asked: How may gifted students use poetry and comics to write about identity? How can the mixing of poetry and comics contribute to media literacy education? Using their poetry comics to connect their ânerd identitiesâ to superheroes, students reported seeing parallels between the trials and tribulations of superhero origin stories and their own âgiftedâ identity
MEANS OF CONVEYANCE: SPOKEN WORD PEDAGOGY, HIP HOP LITERACIES, AND THE CHALLENGES OF FOSTERING POETRY SPACES
Thesis (Ph.D.) - Indiana University, School of Education, 2020This dissertation examined the relationships between teachers, students, and âteaching artistsâ (Graham, 2009) who use poetry as a vehicle for literacy learning. One popular practice is the use of âspoken word,â (Somers-Willett, 2009) a fiery brand of performative poetry popularized by artists from the hip hop music scene (Hill, 2009) and the competitive poetry slam circuit (Woods, 2008). A wealth of qualitative studies extol the virtues of âspoken word pedagogy,â (Kim, 2013; Low, 2011; Weinstein, 2010) noting its power when used as a vehicle for writers to construct literate identities (Fisher, 2007) and form critiques of socio-political issues (Jocson, 2008). To best understand how these dialogic communities operate in precarious times, this study explored the numerous, overlapping spaces where spoken word is used as a pedagogy for multiliteracies. This dissertation employed a practice that Prendergast (2009) called âpoetic inquiry,â a creative approach to qualitative inquiry where the researcher adopts the tools a poet uses to search for truth in the world. To explore critical issues in the global spoken word community, a new, hip-hop-infused version of poetic inquiry was created for this study, called â(re)mixed methods.â The findings of this four year study reveal that collaborative teams of poets often face concrete challenges sustaining educational poetry programs, which threaten the relationships necessary to hearten such communities. Findings also highlight that many participants use poetry to name these barriers that repress them, authoring striking narratives about issues such as economic inequality, the need for school reform, structural racism, gender discrimination, the school-to-prison pipeline, and the unmet mental health needs of students. The implications of these findings challenge stakeholders to consider how spoken word pedagogy ix serves as a conduit for intergenerational dialogue, and could be used to help collaborative learning communities envision a future beyond the challenges they face
Le souffle poétique
This special issue of JCACS amplifies and intersects multiple themes that challenge our capacity to access air. We invited research presented at the 2019 International Symposium on Poetic Inquiry, as well as new poetic inquiry that engages, plays with, ignites and challenges notions of action in a time of legislated inaction, work that counteracts silencing the breath inside our bones. We looked for oxygen where there was none. The editors of this special issue all use poetry as a form of inquiry in their lives and academic work, and we are delighted to share the work of our colleagues from the poetic inquiry community. We believe that this issue demonstrates the value of using poetic inquiry in academia to highlight the voices of those underrepresented and thus is a vital contribution to the research community.Ce numĂ©ro spĂ©cial de RACEC amplifie et croise de multiples thĂšmes qui remettent en question notre capacitĂ© Ă accĂ©der Ă l'air. Nous avons invitĂ© des recherches prĂ©sentĂ©es au Symposium international sur l'enquĂȘte poĂ©tique 2019, ainsi que des nouvelles enquĂȘtes poĂ©tiques qui engagent, jouent avec, enflamment et dĂ©fient les notions d'action Ă une Ă©poque d'inaction lĂ©gifĂ©rĂ©e, un travail qui contrecarre le silence du souffle Ă l'intĂ©rieur de nos os.

Nous pensons que ce numĂ©ro dĂ©montre la valeur de l'utilisation de l'enquĂȘte poĂ©tique dans le monde universitaire pour mettre en lumiĂšre les voix de ceux qui sont sous-reprĂ©sentĂ©s et constitue donc une contribution essentielle Ă la communautĂ© des chercheurs
K2-231 b: A sub-Neptune exoplanet transiting a solar twin in Ruprecht 147
We identify a sub-Neptune exoplanet ( R)
transiting a solar twin in the Ruprecht 147 star cluster (3 Gyr, 300 pc, [Fe/H]
= +0.1 dex). The ~81 day light curve for EPIC 219800881 (V = 12.71) from K2
Campaign 7 shows six transits with a period of 13.84 days, a depth of ~0.06%,
and a duration of ~4 hours. Based on our analysis of high-resolution MIKE
spectra, broadband optical and NIR photometry, the cluster parallax and
interstellar reddening, and isochrone models from PARSEC, Dartmouth, and MIST,
we estimate the following properties for the host star: M, R, and K. This star appears to be single, based on our modeling of the
photometry, the low radial velocity variability measured over nearly ten years,
and Keck/NIRC2 adaptive optics imaging and aperture-masking interferometry.
Applying a probabilistic mass-radius relation, we estimate that the mass of
this planet is M, which would cause a RV
semi-amplitude of m s that may be measurable with existing
precise RV facilities. After statistically validating this planet with BLENDER,
we now designate it K2-231 b, making it the second sub-stellar object to be
discovered in Ruprecht 147 and the first planet; it joins the small but growing
ranks of 23 other planets found in open clusters.Comment: 24 pages, 7 figures, light curve included as separate fil
Autologous humanized PDX modeling for immuno-oncology recapitulates features of the human tumor microenvironment.
BACKGROUND: Interactions between immune and tumor cells are critical to determining cancer progression and response. In addition, preclinical prediction of immune-related drug efficacy is limited by interspecies differences between human and mouse, as well as inter-person germline and somatic variation. To address these gaps, we developed an autologous system that models the tumor microenvironment (TME) from individual patients with solid tumors.
METHOD: With patient-derived bone marrow hematopoietic stem and progenitor cells (HSPCs), we engrafted a patient\u27s hematopoietic system in MISTRG6 mice, followed by transfer of patient-derived xenograft (PDX) tissue, providing a fully genetically matched model to recapitulate the individual\u27s TME. We used this system to prospectively study tumor-immune interactions in patients with solid tumor.
RESULTS: Autologous PDX mice generated innate and adaptive immune populations; these cells populated the TME; and tumors from autologously engrafted mice grew larger than tumors from non-engrafted littermate controls. Single-cell transcriptomics revealed a prominent vascular endothelial growth factor A (VEGFA) signature in TME myeloid cells, and inhibition of human VEGF-A abrogated enhanced growth.
CONCLUSIONS: Humanization of the interleukin 6 locus in MISTRG6 mice enhances HSPC engraftment, making it feasible to model tumor-immune interactions in an autologous manner from a bedside bone marrow aspirate. The TME from these autologous tumors display hallmarks of the human TME including innate and adaptive immune activation and provide a platform for preclinical drug testing
The TESS Grand Unified Hot Jupiter Survey. I. Ten TESS Planets
We report the discovery of ten short-period giant planets (TOI-2193A b,
TOI-2207 b, TOI-2236 b, TOI-2421 b, TOI-2567 b, TOI-2570 b, TOI-3331 b,
TOI-3540A b, TOI-3693 b, TOI-4137 b). All of the planets were identified as
planet candidates based on periodic flux dips observed by NASA's Transiting
Exoplanet Survey Satellite (TESS). The signals were confirmed to be from
transiting planets using ground-based time-series photometry, high angular
resolution imaging, and high-resolution spectroscopy coordinated with the TESS
Follow-up Observing Program. The ten newly discovered planets orbit relatively
bright F and G stars (,~ between 4800 and 6200 K).
The planets' orbital periods range from 2 to 10~days, and their masses range
from 0.2 to 2.2 Jupiter masses. TOI-2421 b is notable for being a Saturn-mass
planet and TOI-2567 b for being a ``sub-Saturn'', with masses of and Jupiter masses, respectively. In most cases, we
have little information about the orbital eccentricities. Two exceptions are
TOI-2207 b, which has an 8-day period and a detectably eccentric orbit (), and TOI-3693 b, a 9-day planet for which we can set an upper
limit of . The ten planets described here are the first new planets
resulting from an effort to use TESS data to unify and expand on the work of
previous ground-based transit surveys in order to create a large and
statistically useful sample of hot Jupiters.Comment: 44 pages, 15 tables, 21 figures; revised version submitted to A
TOI-1259Ab â a gas giant planet with 2.7 per cent deep transits and a bound white dwarf companion
We present TOI-1259Ab, a 1.0RJup gas giant planet transiting a 0.71Râ K-dwarf on a 3.48 d orbit. The system also contains a bound white dwarf companion TOI-1259B with a projected distance of âŒ1600 au from the planet host. Transits are observed in nine TESS sectors and are 2.7 per cent deep â among the deepest known â making TOI-1259Ab a promising target for atmospheric characterization. Our follow-up radial velocity measurements indicate a variability of semiamplitude , implying a planet mass of 0.44MJup. By fitting the spectral energy distribution of the white dwarf, we derive a total age of Gyr for the system. The K dwarfâs light curve reveals rotational variability with a period of 28 d, which implies a gyrochronology age broadly consistent with the white dwarfâs total age
