    “Who We Are On Paper”: Celebrating Writing Identity and Diversity With High School Seniors in a Dialogic ELA Classroom

    Grounded in theory that views language and writing as inextricable from the social event within which it occurs, the purpose of this ethnographic study was to explore how the dialogue produced within the context of a detracked English Language Arts (ELA) classroom contributed to students’ perceptions of their writing identity. The class consisted of a racially, socioeconomically, and academically diverse group of 12th-grade students enrolled in a suburban, public high school. Findings illustrated that writing identity was enacted through multiple iterations of literacy processes embedded in a curriculum that was culturally responsive and implemented through dialogic methods. The analysis of the data from macro, meso, and micro perspectives uncovered two predominant aspects of writing identity. First, students developed understandings of their unique individuality over time that deepened their awareness of writing identity in the writing process, or “who you are on paper.” Second, and interwoven into the first finding, the role of the teacher-student and student-student dialogue through instructional tools, particularly the writer’s notebook and peer review, played an integral role in students’ literacy learning and became another important aspect of writing identity, or “the way you write.” Although research on effective writing methodologies is prolific and valuable, there is less empirical data supporting how students’ cultural backgrounds and educational histories shape their unique writing identities. Implications of this study’s findings suggest that writing identity is a fundamental element in writing development and should be included in existing curricula for the purpose of providing all students with access to effective and equitable writing instruction

    Trying On—Being In—Becoming: Four Women’s Journey(s) in Feminist Poststructural Theory

    Get PDF
    This is the narrative of four women in academia spanning a ten-year relational journey. As a performance collaborative autoethnography, it explores and presents theories of subjectivity and transitional space. Through journals, emails, and dialogue we are trying on, being in, and becoming feminist poststructural thinkers/inquirers/teacher educators. In our work, we explore: How has theory changed our subjectivity, lived experiences and relationships, and moved us from comfortable spaces of knowing to uncomfortable places of becoming? In a series of poetry and performance narratives, we chart our own linked journey(s) in pursuing these questions. As autoethnographers, we grapple with meanings and moments of loss, desire, guilt, and love as a practice of hypomnemata. This study represents a reflective mining of such treasures, capturing moments of rereading and meditation, and a pause, even if an illusionary one, in our intellectual, spiritual, emotional, and embodied journey(s). Our work illustrates how the self looks in transitional space: in motion, contemporaneous, simultaneously in the making and in relation to others. We continue this practice as a pedagogy for being and living out the fictions of our lives

    Formation of toxaphene-like contaminants during simulated paper pulp bleaching

    Toxaphene is a persistent pesticide which is highly toxic to a broad range of organisms including freshwater fish. The sources of Toxaphene are still not clearly understood. Atmospheric transport from the cotton growing districts of the southeastern United States is presently considered the most plausible hypothesis. This mechanism, however, does not adequately explain all of the data on Toxaphene concentrations in different geographical regions of the U.S. In particular, concentrations in the immediate vicinity of the Great Lakes have been increasing, whereas decreases have been observed at Midwestern sites not near these lakes. It is conceivable that environmental chlorination reactions, not involving the manufacture or application of Toxaphene at all, may be generating materials closely related to or indistinguishable from Toxaphene. The objective of our research was to simulate pulp bleaching conditions in the laboratory and determine if Toxaphene-like materials could be produced. The aqueous chlorination of the monoterpenes, camphene, limonene, apinene and 8-pinene produced complex polychlorinated product mixtures. The extent of chlorination was primarily dependent on pH and light conditions. At pH 2 and exposed to sunlight product mixtures were obtained that had striking similarities to Toxaphene. At higher pH or in the dark, less extensive but still substantial chlorination took place; these lower chlorinated compounds could be mistaken for biologically degraded Toxaphene in environmental samples. We conclude that Toxaphene-like mixtures may conceivably be formed under environmental conditions, but the actual extent of formation of such mixtures and the degree to which they may contribute to apparent Toxaphene in natural samples remain to be assessed.U.S. Department of the InteriorU.S. Geological SurveyOpe

The definitive version was published in Geochemistry, Geophysics, Geosystems 18 (2017): 75–92, doi:10.1002/2016GC006537.Tidal oscillations of venting temperature and chlorinity have been observed in the long-term time series data recorded by the Benthic and Resistivity Sensors (BARS) at the Grotto mound on the Juan de Fuca Ridge. In this study, we use a one-dimensional two-layer poroelastic model to conduct a preliminary investigation of three hypothetical scenarios in which seafloor tidal loading can modulate the venting temperature and chlorinity at Grotto through the mechanisms of subsurface tidal mixing and/or subsurface tidal pumping. For the first scenario, our results demonstrate that it is unlikely for subsurface tidal mixing to cause coupled tidal oscillations in venting temperature and chlorinity of the observed amplitudes. For the second scenario, the model results suggest that it is plausible that the tidal oscillations in venting temperature and chlorinity are decoupled with the former caused by subsurface tidal pumping and the latter caused by subsurface tidal mixing, although the mixing depth is not well constrained. For the third scenario, our results suggest that it is plausible for subsurface tidal pumping to cause coupled tidal oscillations in venting temperature and chlorinity. In this case, the observed tidal phase lag between venting temperature and chlorinity is close to the poroelastic model prediction if brine storage occurs throughout the upflow zone under the premise that layers 2A and 2B have similar crustal permeabilities. However, the predicted phase lag is poorly constrained if brine storage is limited to layer 2B as would be expected when its crustal permeability is much smaller than that of layer 2A.Woods Hole Oceanographic Institution; NOAA; National Science Foundation Grant Numbers: 9820105 , 0120392 , 0701196 , 0751868 , 08190042017-07-1

    Synthesis and characterization of La<sub>0.8</sub>Sr<sub>1.2</sub>Co<sub>0.5</sub>M<sub>0.5</sub>O<sub>4-?</sub> (M=Fe, Mn)

    The M4+-containing K2NiF4-type phases La0.8Sr1.2Co0.5Fe0.5O4 and La0.8Sr1.2Co0.5Mn0.5O4 have been synthesized by a sol-gel procedure and characterized by X-ray powder diffraction, thermal analysis, neutron powder diffraction and Mössbauer spectroscopy. Oxide ion vacancies are created in these materials via reduction of M4+ to M3+ and of Co3+ to Co2+. The vacancies are confined to the equatorial planes of the K2NiF4-type structure. A partial reduction of Mn3+ to Mn2+ also occurs to achieve the oxygen stoichiometry in La0.8Sr1.2Co0.5Mn0.5O3.6. La0.8Sr1.2Co0.5Fe0.5O3.65 contains Co2+ and Fe3+ ions which interact antiferromagnetically and result in noncollinear magnetic order consistent with the tetragonal symmetry. Competing ferromagnetic and antiferromagnetic interactions in La0.8Sr1.2Co0.5Fe0.5O4, La0.8Sr1.2Co0.5Mn0.5O4 and La0.8Sr1.2Co0.5Mn0.5O3.6 induce spin glass properties in these phases
