Staying Connected – Interactive Student Learning during the COVID Transition to Remote Learning

Background. How can we transition courses in one week, while maintaining a similar experience for students? This was probably the initial response by faculty across universities as they transitioned to remote learning, mid-semester, in response to the SARS-CoV-2 pandemic. Our approach is supported by the ICAP framework which posits that “as activities move from passive to active to constructive to interactive, students undergo different knowledge-change processes and, as a result, learning will increase.” (Chi and Wylie, 2014) Purpose/Hypothesis. How we could foster students’ interactions with course material, instructors, and their peers using collaborative technology and course activities? It was hypothesized that a collaborative environment, coupled with appropriately designed activities, would promote the interactive learning described by the ICAP framework. Design/Method. Faculty members used Microsoft Teams (Teams) and Marquette University’s Learning Management System Desire2Learn (D2L) for their courses. Each instructor developed student groups to promote peer and instructor engagement via the Teams channel function. Results. Initial results from Likert 5-point scale responses support three positive findings to this approach: Finding 1 (Instructor Engagement and Student Confidence): Students had a positive reaction to the instructor engagement (4.67 ± 0.6) and student confidence (4.07 ± 1.1). Finding 2 (Consistent Coursework): Students reported the amount of work in courses with the interactive tools was consistent (3.90 ± 1.2) with the in-class experience. Finding 3 (Collaborative Technology): Using collaborative technology (3.84 ± 1.2) enabled the students to successfully interact with their peers. The survey also provided data on opportunities for improvement for future on-line courses: Opportunity 1 (Communication): Student communication (2.57 ± 1.5) is still a barrier with collaborative technology. Opportunity 2 (On-line Format): Students also reported an overall dislike (2.44 ± 1.4) of the on-line learning format. Conclusions. The use of Teams shows that instructor engagement contributes the most to the positive experiences for confidence, consistency, and use of collaborative technology. We believe there are opportunities to develop more advantages than traditional approaches and will provide students an easier transition to industry, which already use these remote communication tools

Biocultural conservation and urban and disturbed areas revegetation of Puerto Madryn, Chubut, Argentina

Las últimas décadas se han caracterizado por la pérdida de biodiversidad y de servicios ambientales y culturales, ante el avance sobre los ambientes naturales. La ciudad de Puerto Madryn se ubica entre playas y un ambiente semiárido de meseta en la provincia fitogeográfica del Monte. En el año 2020, el Jardín Botánico de la Patagonia Extraandina (JBPE) obtuvo financiamiento del Global Botanic Garden Fund (GBGF-45042) para el proyecto: “Producción de Condalia microphylla Cav. (piquillín), Hyalis argentea D. Don ex Hook. & Arn (olivillo) y Atriplex lampa (Moq.) D.Dietr. (zampa), para la conservación biocultural y revegetación urbana y de zonas disturbadas de Puerto Madryn, Chubut, Argentina”. El objetivo es revegetar espacios urbanos a fin de conservar la biodiversidad nativa. Para ello, se colectaron las semillas y los tratamientos pregerminativos fueron: lavados con agua corriente para la eliminación de sales y estratificación en frío (A. lampa), escarificación con ácido sulfúrico y lavados con agua destilada (C. microphylla) y sin tratamiento (H. argentea). Se sembraron en bolsas plásticas con mezcla de tierra fértil, monte y perlita, y se mantuvieron bajo riego manual según requerimiento 100 plántulas de cada especie. La interdisciplinaridad del proyecto y sus etapas (producción, replantación y transferencia a través de talleres participativos educativos) promoverán el valor etnobotánico, ecológico, biocultural y uso responsable de los recursos vegetales.Fil: Duro, Veronica Nidia.

Q’UMARA

El concepto de vida saludable es cada vez más común entre los jóvenes y adultos en el Perú, lo cual va relacionada con una mejor alimentación. Según estudios que se realizaron en las puertas de clínicas, muchas personas que siguen este estilo de vida buscan evitar una gran enfermedad, el Cáncer. A pesar que esta no es la primera causa de muerte, sino los paros cardiacos, el tratamiento es doloroso y conllevarlo es difícil, por lo cual muchas personas buscan formas sobre cómo evitarlo. De esta forma, los autores de este proyecto investigaron que los frutos oscuros y el yogurt mitigan la aparición de células cancerígenas. Por ello, se creó el emprendimiento de Q’umara, el cual ofrece un yogurt natural con toppings de frutos oscuros totalmente orgánicos. En el presente informe se detallarán el público objetivo y los planes que se llevarán al cabo para que la realización de este proyecto sea exitosa. Se necesitará un capital de 44690 nuevos soles y levantar fondos por 25940 nuevos soles para completar la inversión. Cabe resaltar que los indicadores de este proyecto son llamativos; por ejemplo, el VAN es de 46163 nuevos soles. Por otra parte, el periodo de recupero será en el mes 21.20. Además, el indicador de beneficio costo será de 4.39. Por ello, esperamos convencer a los inversionistas con esta gran idea de negocio.This project was born from the idea that healthy lifestyle is becoming more popular in Peru, which is related to healthy food. According to results of studies that were carried out at the doors of clinics, many people who follow this lifestyle seek to avoid a major disease, Cancer. Although this is not the first cause of death, the treatments are very painful and ruins quality of life This is where 5 students from Universidad Peruana de Ciencias Aplicadas realized that people seek to prevent cancer through their diet. So, they researched about what kind of food could prevent this disease and the results were thar dark fruits and yogurt mitigate the appearance of cancer cells. For this reason, Q’umara was created, which offers a natural yogurt with totally organic dark fruit toppings. This report will detail the target and the plans that will be carried out to make this project successful. A capital of 44690 nuevos soles will be needed. However, as shareholders, a part of these will be placed, but it will be necessary to raise funds for 25,940 nuevos soles to complete the investment. Indicators of this project are very attractive. For example, the Net Present Value discounted with the WACC is 46163 nuevos soles. On the other hand, the recovery period will be in month 21.20. In addition, the cost benefit indicator is 4.39. With these indicators we want to show the potential of this project.Trabajo de investigació

Utilization of mechanical power and associations with clinical outcomes in brain injured patients. a secondary analysis of the extubation strategies in neuro-intensive care unit patients and associations with outcome (ENIO) trial

BackgroundThere is insufficient evidence to guide ventilatory targets in acute brain injury (ABI). Recent studies have shown associations between mechanical power (MP) and mortality in critical care populations. We aimed to describe MP in ventilated patients with ABI, and evaluate associations between MP and clinical outcomes.MethodsIn this preplanned, secondary analysis of a prospective, multi-center, observational cohort study (ENIO, NCT03400904), we included adult patients with ABI (Glasgow Coma Scale <= 12 before intubation) who required mechanical ventilation (MV) >= 24 h. Using multivariable log binomial regressions, we separately assessed associations between MP on hospital day (HD)1, HD3, HD7 and clinical outcomes: hospital mortality, need for reintubation, tracheostomy placement, and development of acute respiratory distress syndrome (ARDS).ResultsWe included 1217 patients (mean age 51.2 years [SD 18.1], 66% male, mean body mass index [BMI] 26.3 [SD 5.18]) hospitalized at 62 intensive care units in 18 countries. Hospital mortality was 11% (n = 139), 44% (n = 536) were extubated by HD7 of which 20% (107/536) required reintubation, 28% (n = 340) underwent tracheostomy placement, and 9% (n = 114) developed ARDS. The median MP on HD1, HD3, and HD7 was 11.9 J/min [IQR 9.2-15.1], 13 J/min [IQR 10-17], and 14 J/min [IQR 11-20], respectively. MP was overall higher in patients with ARDS, especially those with higher ARDS severity. After controlling for same-day pressure of arterial oxygen/fraction of inspired oxygen (P/F ratio), BMI, and neurological severity, MP at HD1, HD3, and HD7 was independently associated with hospital mortality, reintubation and tracheostomy placement. The adjusted relative risk (aRR) was greater at higher MP, and strongest for: mortality on HD1 (compared to the HD1 median MP 11.9 J/min, aRR at 17 J/min was 1.22, 95% CI 1.14-1.30) and HD3 (1.38, 95% CI 1.23-1.53), reintubation on HD1 (1.64; 95% CI 1.57-1.72), and tracheostomy on HD7 (1.53; 95%CI 1.18-1.99). MP was associated with the development of moderate-severe ARDS on HD1 (2.07; 95% CI 1.56-2.78) and HD3 (1.76; 95% CI 1.41-2.22).ConclusionsExposure to high MP during the first week of MV is associated with poor clinical outcomes in ABI, independent of P/F ratio and neurological severity. Potential benefits of optimizing ventilator settings to limit MP warrant further investigation

Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago

Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.
