Structural Geology and Cenozoic Deformation: Western Northern Range, Trinidad
Full text linkThe Northern Range, Trinidad underwent deformation due to oblique collision of Caribbean plate with northern South America, which was then followed by transform plate motion. Deformation began in the late Miocene when sedimentary protoliths were ductility deformed and metamorphosed to greenschist facies; this event and subsequent transform deformation drove exhumation of these rocks to the surface and created their high topography. This project provides constraints of the structural history of the western Northern Range where bedrock mapping and structural analyses are most complete. Initial geologic mapping of Northern Range, which continued from the 1950s,1960s, and 1990s, focused on attempting to establish and map a protolith stratigraphy. Our new approach has been to simply map the observed metamorphic rock types. We supplement our new map with abundant mesoscopic structural fabric measurements collected from roadcut, streambed, and quarry exposures. We synthesized the new map and all structural data into a GIS geodatabase. The data were used to construct cross-sections and stereonets along a continuous N-S transect across the entire western Northern Range. Our analyses highlight three major phases of deformation in the western Northern Range. D1 (Early Miocene) produced a S1 foliation that completely transposed the original stratigraphy and dips south at an azimuth between 150-220°. D2 folded S1 into asymmetric trains of south-verging m- to dm-scale mesoscopic folds. D3 produced conjugate sets of NE-SW- and NW-SE-trending f3 folds. The timing of D2 is not well constrained. D3 is probably associated with Pliocene extension related to the local development of pull-apart basins. Our cross-section highlights: 1) range front domains of upright NW-SE trending folds, and 2) the range-bounding Arima Fault zone, a ~100m wide zone of young, but inactive (Plio-Pleistocene), ~E-W trending, sub-vertical (both N- and S-dipping), predominantly dip-slip, normal sense, faulting

Building Speech Pattern 7: Picture Stimuli
Full text linkBuilding Speech Pattern 7: Picture Stimuli is part 7 of 8 in the picture stimuli to accompany the Building Speech & Quantifying Complexity documents. To see the full series, visit: https://digitalcommons.augustana.edu/cgi/siteview.cgi/csdbuildingspeech
Building Speech & Quantifying Complexity is a dual approach to treating and evaluating articulatory complexity in child speech. It has two components: Building Speech and Quantifying Complexity. These two components can be used independently or together. When used together, the speech-language pathologist has a method for selecting goals and targets of varying levels of articulatory difficulty, plus a means for measuring changes in a child’s words, targeted and produced, at one point in time or over time.
The Building Speech & Quantifying Complexity materials include a manual, picture cards for each of the eight speech patterns, and worksheets for the Index of Phonetic Complexity. The manual provides speech-language pathologists with foundational information, so that they can individualize their assessments and interventions to meet the needs of the children on their caseloads with challenging speech sound disorders. It is not intended to be a lock-step program, but rather, an approach to be used creatively and flexibly by speech-language pathologists to address the needs of the individual children on their caseloads. Building Speech & Quantifying Complexity is designed to assess and treat speakers of American English, although the components can be adapted to fit the phonetics and phonology of other languages
Coming Out Culture and LGBTQ+ Teachers
Full text linkTeachers who are part of the LGBTQ+ community face unique circumstances when it comes to educating students about LGBTQ+ and other social issues, especially when they have multiple marginalized identities. Some teachers may not be safe or comfortable coming out, while others may feel pressured to come out in order to provide positive queer representation for students. The culture surrounding coming out in the U.S. may significantly contribute to this pressure. This essay analyzes non-binary teachers\u27 perspectives on coming out in the classroom. Through this analysis, insight is provided into the ways in which queer teachers may intentionally or unintentionally contribute to coming out culture, and other harmful generalizations about queer people, through their processes of coming out. Ultimately, this information helps to weigh the benefits and drawbacks of coming out in the classroom, on a personal and societal level
Augustana Seniors Fall 1885: Joel L. Haff
Full text linkJoel L. Haff was a senior at Augustana College, Rock Island, Illinois, in the fall of 1885. His name appears in the college catalog of 1885-1886, along with his birthplace, the year of his birth, and a few other facts. From this start, we researched the genealogy and family history of Joel L. Haff. This paper contains a short biography of Joel, a report on his ancestors, a report on his descendants, and some open questions for further research

crooked smile
Full text linkAs a songwriter, I love connecting my poetry to songs. There are so many similarities between life and music, and that is just beautiful to me. I wrote this poem about very real experiences I have had, about the idea of sugarcoating reality for the sake of what life really looks like under the surface. This is similar to my songs, when my melodies are seen as catchy but the lyrics are overlooked. As a queer woman, there have been many times where I have felt silenced, or where my pain has been overlooked and my lyrics haven\u27t been taken seriously. I wrote this poem for anyone who deals with unjust oppressions based off of their identities, so that they don\u27t feel alone in their struggle to sing out
