Reflections on (de)colonialism in language documentation

With origins in colonial logics and institutions, language documentation practices can reinforce colonial power hierarchies and norms in ways that work against the needs and values of Indigenous language communities. This paper highlights major patterns through which this occurs, along with their effects, and models how language documentation can be structured in ways that are more grounded in the experiences and perspectives of the communities that use it. I propose decolonial interventions that emerge from Indigenous research principles and perspectives, and illustrate how these practices can better support language community needs while also improving the scientific value of language documentation.National Foreign Language Resource Cente

Hear Our Languages, Hear Our Voices: Storywork as Theory and Praxis in Indigenous-Language Reclamation

Storywork provides an epistemic, pedagogical, and methodological lens through which to examine Indigenous language reclamation in practice. We theorize the meaning of language reclamation in diverse Indigenous communities based on firsthand narratives of Chickasaw, Mojave, Miami, Hopi, Mohawk, Navajo, and Native Hawaiian language reclamation. Language reclamation is not about preserving the abstract entity “language,” but is rather about voice, which encapsulates personal and communal agency and the expression of Indigenous identities, belonging, and responsibility to self and community. Storywork – firsthand narratives through which language reclamation is simultaneously described and practiced – shows that language reclamation simultaneously refuses the dispossession of Indigenous ways of knowing and refuses past, present, and future generations in projects of cultural continuance. Centering Indigenous experiences sheds light on Indigenous community concerns and offers larger lessons on the role of language in well-being, sustainable diversity, and social justice.Ye

Storying an interconnected web of relationships in Indigenous language reclamation work and scholarship

Indigenous language work is manifested in a diversity of community-led responses of resilience and persistence. Indigenous persons who are reclaiming their languages have entered academia with goals of contributing to community language reclamation efforts and broader resurgence movements. Adapting Archibald’s (2008) concept of storywork—experiential narratives that privilege a cultural lens—we take a dialogic approach for scholar-educators to story their Indigenous language work within a web of interrelated relationships. From our positionalities as Chikashsha, Hopisino, Kanaka Hawaiʻi, myaamia, and Brazilian scholars, we ask and reflect on the following questions: Who are we storying with and for? What does language work look like in our community contexts and academic collaborations? How do we define cultural praxis in our work? What principles inform and emerge from our collective work? How do we co-construct knowledge that will sustain our language work and relationships? This reflective and reflexive process engages and maintains a continual balance of the cumulative past and present toward the future. Foremost, we aspire to act and work consistently in ways that are good for our peoples and communities, which includes a view of the research we undertake as purposeful journeying (Hill & Wilkinson, 2014) within our academic contexts and scholarship.Ye

Patient complexity in quality comparisons for glycemic control: An observational study

<p>Abstract</p> <p>Background</p> <p>Patient complexity is not incorporated into quality of care comparisons for glycemic control. We developed a method to adjust hemoglobin A1c levels for patient characteristics that reflect complexity, and examined the effect of using adjusted A1c values on quality comparisons.</p> <p>Methods</p> <p>This cross-sectional observational study used 1999 national VA (US Department of Veterans Affairs) pharmacy, inpatient and outpatient utilization, and laboratory data on diabetic veterans. We adjusted individual A1c levels for available domains of complexity: age, social support (marital status), comorbid illnesses, and severity of disease (insulin use). We used adjusted A1c values to generate VA medical center level performance measures, and compared medical center ranks using adjusted versus unadjusted A1c levels across several thresholds of A1c (8.0%, 8.5%, 9.0%, and 9.5%).</p> <p>Results</p> <p>The adjustment model had R²= 8.3% with stable parameter estimates on thirty random 50% resamples. Adjustment for patient complexity resulted in the greatest rank differences in the best and worst performing deciles, with similar patterns across all tested thresholds.</p> <p>Conclusion</p> <p>Adjustment for complexity resulted in large differences in identified best and worst performers at all tested thresholds. Current performance measures of glycemic control may not be reliably identifying quality problems, and tying reimbursements to such measures may compromise the care of complex patients.</p

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
