IMPACT: The Journal of the Center for Interdisciplinary Teaching and Learning. Volume 9, Issue 1, Winter 2020

Explicitly established to foreground interdisciplinary teaching and learning, Impact also welcomes evidence and discussion of experiential learning. Often the two – interdisciplinary teaching and experiential learning – co-exist. Yet even when they do not, both practices model how to think in myriad ways and to notice how knowledge is constructed. As our winter 2019 issue makes clear, interdisciplinary teaching and learning and experiential learning often begin with questions. Why does it matter that students grapple directly with archival material? What happens when undergraduates practice psychology by training dogs? Do students understand financial literacy? This issue also asks questions about students’ reading habits and faculty expectations of them as readers

A Daring Voice: Confessional Poetry of the 1970s from Argentina and the United States

Daring to confront difficult socio-political realities on the page, Argentine and United States poets writing in the late 1960s and early 1970s strove against systems of silence. Implementing direct and indirect poetics, each set of poets embodied, in differing and overlapping ways, elements of the confessionalist mode, at once relational and witnessing. Their poetry in collections from these particular years reflected the risk in their auto-positioning as subjects within their poems and with complex relationships with their audience, and in their usage of language, sometimes fragmented, protective, or urgent. They committed personal experience to the page, and in conveying their experience through narrative and lyric techniques, they opened their lines to provide access to masses of readers who had known the same difficult truths and shared in those realities. These poets, here represented by Juan Gelman, Olga Orozco, Francisco Paco Urondo, Elizabeth Bishop, Anne Sexton, and Adrienne Rich, conducted a risk-taking socio-political poetics of relation demanding awareness and change. In the United States, the experiences that Bishop, Rich, and Sexton wrote of in their work of this historical moment pertained to socially taboo issuesmental illness, alcoholism, abuse, marital strain, non-normative sexuality, and unequal gender treatmentan address of which that had been fought for in the protests and movements in the 1960s. In Argentina, Gelman, Orozco, and Urondo were writing of the increasing harms being committed by state military forces against citizens and that threatened their own lives as subversives working counter to the interests of their national government. These years constituted a time of darkening hope, as Argentina headed into successive military dictatorships. In response, Gelman and Urondo, along with other authors, developed a more pointed, witnessing, unmistakable, yet emotional and intimate style of writing that paralleled that of the United States poets. Differing from all four of these poets slightly, I also observe the indirect poetics of acknowledgment of Bishop and Orozco, who wrote concurrently with the others, yet communicated autobiographical and socio-political truths through more buried and protective technical means. This dissertation observes the literary commonalities and discrepancies in these national poetries that upheld the dual ethic of art and socio-political witness. I world the terms confessional, conversational, and testimonial, cross-applying them to the different national poetics and showing how each implemented aspects of the modes. I set forth with the assumption that confessionalism is relational and necessarily enacts vulnerability, skepticism, a critical stance, and risk in its very practice of communicating experience both personal and shared. The trajectories in American literature and through events affecting both nations as well as the globeincluding protest movements for identity rightsled these Argentine and United States poets to a fascinatingly common space despite their very disparate stakes for writing, which later in the decade would lead to exile and death in the country to the south. These brave writers harnessed devastating fact and made socio-political art by representing multitudes of others with a belief and insistence on the power of language, knowledge, and relation

Evidencia empírica del desarrollo sostenible: relación de causalidad entre el crecimiento económico y deterioro medio ambiental de Ecuador y América Latina y El Caribe

This article is an inductive argumentation and an empirical-analytical paradigm that evaluates the actual relationship between Gross Domestic Product (GDP) per capita and the Carbon Dioxide (CO2) in the case of Ecuador and to compare it with Latin America and the Caribbean within a period of analysis from 1960 to 2011. It was developed an Augmented Dickey-Fuller unit root (ADF), a Granger Causality Test and a Johansen Cointegration test. It was obtained a VAR model with two variables with a number of 14 lags – VAR2(14) which were tested for which were tested for causality by demonstrating a bidirectionality for Latin America and the Caribbean and a unidirectionality of GDP per capita to CO2 for the Ecuador.

Spring Tide Wait

These poems work the geography they possess, moving as fully as their peripheral vision permits; their area delineated by a quietly biding moment revealing the narrator's uncertainties and desires, and especially her romantic relationship. The visual efforts are detailed and many times drawn from the natural and/or the foreign, traveling from the New England coast to Spain and Argentina, while incorporating translated works from Latin American poets--Heberto Padilla and Dulce María Loynaz--, the wonder at the expansiveness of another place isolating and contrasting

Performance modelling and simulation of a 100km hybrid sounding rocket.

M.Sc.Eng. University of KwaZulu-Natal, Durban 2013.The University of KwaZulu-Natal (UKZN) Phoenix Hybrid Sounding Rocket Programme was established in 2010. The programme’s main objective is to develop a sounding rocket launch capability for the African scientific community, which currently lacks the ability to fly research payloads to the upper atmosphere. In this dissertation, UKZN’s in-house Hybrid Rocket Performance Simulator (HYROPS) software is used to improve the design of the Phoenix-2A vehicle, which is intended to deliver a 5 kg instrumentation payload to an apogee altitude of 100 km. As a benchmarking exercise, HYROPS was first validated by modelling the performance of existing sub-orbital sounding rockets similar in apogee to Phoenix-2A. The software was found to approximate the performance of the published flight data within 10%. A generic methodology was then proposed for applying HYROPS to the design of hybrid propellant sounding rockets. An initial vehicle configuration was developed and formed the base design on which parametric trade studies were conducted. The performance sensitivity for varying propulsion and aerodynamic parameters was investigated. The selection of parameters was based on improving performance, minimising cost, safety and ease of manufacturability. The purpose of these simulations was to form a foundation for the development of the Phoenix-2A vehicle as well as other large-scale hybrid rockets. Design chamber pressure, oxidiser-to-fuel ratio, nozzle design altitude, and fin geometry were some of the parameters investigated. The change in the rocket’s propellant mass fraction was the parameter which was found to have the largest effect on performance. The fin and oxidiser tank geometries were designed to avoid fin flutter and buckling respectively. The oxidiser mass flux was kept below 650 kg/m2s and the pressure drop across the injector relative to the chamber pressure was maintained above 15% to mitigate the presence of combustion instability. The trade studies resulted in an improved design of the Phoenix-2A rocket. The propellant mass of the final vehicle was 30 kg less than the initial conceptual design and the overall mass was reduced by 25 kg. The Phoenix-2A vehicle was 12 m in length with a total mass of 1006 kg. The fuel grain length of Phoenix-2A was 1.27 m which is approximately 3 times that of Phoenix-1A. The benefit of aluminised paraffin wax as a fuel was also investigated. The results indicated that more inert mass can be delivered to the target apogee of 100 km when using a 40% aluminised paraffin wax

Mentoring Fellows into Career Educators through a Multispecialty Clinician-Educator Course.

BACKGROUND: Subspecialty fellows are a unique group of trainees for whom there currently exist few opportunities to pursue formal training as clinician-educators, as singular fellowship programs often face significant obstacles to implementing such coursework. OBJECTIVE: To develop, implement, and assess a clinician-educator course for fellows from multiple subspecialty fellowships at a single large academic medical center. METHODS: Our course, entitled Fellow as Clinician-Educator, was initiated across numerous fellowship programs from August 2021 to April 2023 at University of California San Diego Health. The synchronous component of the curriculum included four half-day workshops targeting various clinician-educator subcompetencies. The course also included ongoing educational opportunities, longitudinal mentorship, and a medical education capstone project. Measures with pre and postcourse knowledge assessments and surveys were performed to evaluate the courses impact in this prospective observational cohort. RESULTS: Forty-six fellows enrolled in the course. Overall, there was statistically significant improvement in learners confidence across 16 of 18 clinician-educator skills surveyed (P < 0.05). Participants demonstrated improvement in nine core topics for clinician-educators, achieving statistical significance for feedback (P = 0.0058), lecture slide design (P = 0.0006), and multimedia design principles (P = 0.0416). The course facilitated medical education scholarship in the form of 4 grant submissions, 7 manuscripts, 27 presented abstracts, and 24 curricular innovations. CONCLUSION: Implementation of a multispecialty clinician-educator course for subspecialty fellows is feasible, effective, and facilitates academic scholarship in medical education. Such programs may also serve to circumnavigate many challenges that single fellowship programs face when attempting to pursue their own directed clinician-educator courses

Crowds as complex adaptive systems: strategic implications for law enforcement

Law enforcement attempts to control unruly crowds have come under increased scrutiny in light of recent unrest in Ferguson, Missouri; Baltimore, Maryland; and other locales across the United States. Resultant criticism is forcing law enforcement agencies nationwide to review their civil-unrest policies. Crowd behavior resulting from police actions is an important component of crowd control. Viewing crowds from a systems perspective, as done in this thesis, provides powerful new insights to help law enforcement assess potential crowd behaviors. Through this new awareness, this thesis makes recommendations regarding policies, training, and equipment that law enforcement can use to make better-informed decisions related to crowd control.http://archive.org/details/crowdsscomplexda1094548549Lieutenant, Massachusetts State PoliceApproved for public release; distribution is unlimited

Análisis de la distribución equitativa de cargas y beneficios en la gestión del suelo.

En el presente trabajo se incluye un “análisis de la distribución de cargas y beneficios en la gestión del suelo”, incorporando el “principio de equidad” y con la finalidad de adoptarlo como uno de los “instrumentos de la planificación urbanística”, conforme lo estipula la “Ley Orgánica de Ordenamiento Territorial Uso y Gestión de Suelo” (2016) y su “reglamento” (2019), pero su aplicación es incipiente en nuestro medio debido a la falta de “normas procedimentales” expedidas por los “Gobiernos Autónomos Descentralizados” del nivel municipal que tienen la “competencia exclusiva de regular y controlar la ocupación y el uso del suelo” en su clasificación urbano y rural; para ello es preciso estudiar la normativa extranjera y analizar su importación y adaptación a las ordenanzas que deben expedirse para su observancia en el cumplimiento de los “Planes de Desarrollo y Ordenamiento Territorial”, en adelante “PDOT” y “Planes de Uso y Gestión de Suelo”, en adelante “PUGS”, poniendo fin al libre arbitrio que prima en el “proceso de aprobación” de proyectos habitacionales ubicados especialmente en “suelo urbano no consolidado”, con el ánimo de que el proceso normado incorpore “espacios verdes, equipamientos y edificaciones urbanas” en “beneficio de la comunidad”, en correspondencia con el otorgamiento de la “facultad constructiva” que nace del “planeamiento urbanístico”, a favor del “promotor inmobiliario”; persiguiendo como fin, la incorporación del concepto de ciudades consolidadas y resilientes, donde sus gobiernos cantonales sean capaces de atender de forma eficiente la demanda de servicios municipales en sus jurisdicciones y que de forma ordenada coadyuven al desarrollo local.This work includes an "analysis of the distribution of burdens and benefits in land management", incorporating the "principle of equity" and adopting it as one of the "instruments of urban planning", which has been regulated in the "Law Organic of Land Use and Management of Land ”(2016) and its“ regulation ”(2019), but its application is incipient in our environment due to the lack of“ procedural norms ”issued by the“ Decentralized Autonomous Governments ”of the municipal level that they have the “exclusive competence to regulate and control the occupation and use of the land” in their urban and rural classification; For this, it is necessary to study foreign regulations and analyze their importation and adaptation to the ordinances that must be issued for their observance in compliance with the "Development Plans and Territorial Organization", hereinafter "PDOT" and "Plans for the Use and Management of Land ”, hereinafter“ PUGS ”, putting an end to the free will that prevails in the“ approval process ”of housing projects located especially on“ unconsolidated urban land ”, with the aim that the regulated process incorporates“ green spaces, facilities and urban buildings ”for the“ benefit of the community ”, in correspondence with the granting of the“ constructive power ”that arises from the“ urban planning ”, in favor of the“ real estate developer ”; pursuing as a goal, the incorporation of the concept of consolidated and resilient cities, where their cantonal governments are able to efficiently meet the demand for municipal services in their jurisdictions and that contribute to local development in an orderly manner
