UNIDADES DE ANÁLISIS PARA EL ESTUDIO DE PARTICIPACIONES DE ALUMNOS DE EDUCACIÓN A DISTANCIA

La aplicación de las Tecnologías de la Información y la Comunicación (TICs) en el ámbito de la educación, ha dado lugar al surgimiento de nuevos escenarios para el desarrollo de la misión docente propia de las instituciones universitarias. En los foros de discusión, los alumnos pueden ver la participación de sus compañeros de clase y el profesor puede enriquecer con comentarios a medida que el diálogo progresa (Scagnoli, 2000).A pesar de que existen diversos estudios sobre los análisis de contenido en los foros de discusión, algunas revisiones recientes llaman la atención sobre la falta de rigor metodológico. Entre estas fallas se encuentra la falta de marcos teóricos que sustenten la aproximación empírica y de procedimientos claros en la elección de la unidad de análisis y en la segmentación de las contribuciones.Desde esta perspectiva, en el presente trabajo se propone el uso de la palabra como unidad de análisis, así como las medidas de análisis de type/token pues se ha considerado como un indicador de contenido ya que el número de palabras diferentes refleja la riqueza y complejidad del repertorio del vocabulario del hablante.Las unidades de análisis propuestas en este trabajo se exhiben como novedosas en el estudio de los contenidos virtuales generados por estudiantes de educación a distancia.

Eliciting Complex Thinking through Open Educational Resource Projects

Since the COVID-19 pandemic, the use of Open Educational Resources (OERs) has increased due to its advantages for academic activities and educational quality. Hence, Higher Education Institutions (HEIs) have sought to develop strategies to promote curricular and extracurricular activities that favor developing disciplinary and transversal competencies such as complex thinking and its meta-competencies: critical, systemic, scientific, and innovative thinking, oriented to favor problem-solving among students and the academic community. The main objective of this study was to analyze how using OERs in virtual education can promote the development of complex thinking as a transversal competency in higher education. We analyzed the content of 65 educational projects in a webinar aimed at promoting the adoption of OERs in the professional practice of the educational community. Each project had to comply with specific requirements, from the project's identification and description to measuring and evaluating the results and its impact and added value. Once all the projects were reviewed, the responses were classified into defined categories for better presentation; the sub-competency of complex thinking promoted by each project element was identified qualitatively. The results highlight how an OER can, through concrete activities, elicit complex thinking and its sub-competencies in higher education. The present study adds new evidence to the literature regarding boosting OERs as a tool to develop competencies aligned with UNESCO recommendations and contribute to fulfilling the Sustainable Development Goals in education

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Critical Thinking and Student Well-Being: An Approach in University Students

Human well-being is a dynamic and changing concept as it depends on personal, social, cultural, and political factors and varies over time according to individual circumstances. Therefore, it is essential to address this issue from a comprehensive and multidisciplinary approach, seeking that individuals, from an early age, manage to develop skills and attitudes that allow them to achieve a balance in their lives. This article presents the results of the measurement of students’ perceived achievement of the competence of complex thinking in a subject focused on human development. Specifically, the research sought to identify whether there is a relationship between the level of critical thinking and the acquisition of skills associated with human well-being. The selection of critical thinking is based on the fact that this cognitive ability is one of the subcompetencies included in complex thinking. The sample was a group of university students from different disciplines and educational levels. Methodologically, descriptive analyses were made on the means of students’ responses to a validated instrument measuring the perceived achievement of complex thinking competency and its subcompetencies and the final evaluations of the students’ course. In conclusion, an improvement in the perception of achievement of complex thinking competency and its subcompetencies is demonstrated in the students, with critical thinking that achieved the best means, its increase being significant for the whole group and for women but not for men. In this sense, although it was not possible to demonstrate a statistically significant relationship between the development of this subcompetency and the acquisition of tools associated with well-being, data showing a possible association between these elements were obtained

Examining the level of perceived achievement of complex thinking competency in health sciences students and its relevance to the graduate profile

This article presents the findings of a study conducted on health sciences students in their last semester of training regarding their perceived achievement of the complex thinking competency and its sub-competencies. The objective was to gain insight into how these students perceive the cognitive competencies and skills acquired during their university career as relevant to meet the challenges of their future professions. This study contrasts the perception of achievement of complex thinking competence by gender of the participants, as well as compared to students from other disciplines, with the intention of identifying significant differences. This competency's selection lies in its relevance to decision-making when facing problems, which is fundamental for any contemporary professional. This study relied on a representative convenience sample of graduating candidates from a university in western Mexico. Methodologically, the researchers used descriptive analyses and a validated instrument. The results indicated that the sample students' perceived achievement was very high and balanced, i.e., no significant differences existed by gender or the perception of their sub-competencies. This study revealed a significant difference compared to other disciplinary areas; the medical and health sciences graduate candidates' perceived achievement of competency development was higher

Social Entrepreneurship, Complex Thinking, and Entrepreneurial Self-Efficacy: Correlational Study in a Sample of Mexican Students

This article presents the results of a study conducted on a sample population of students attending a technological university in western Mexico. The development of the entrepreneurial self-efficacy competency was evaluated within a process of ideation of social entrepreneurship projects to develop social entrepreneurship and complex thinking competencies. A multivariate descriptive analysis was implemented to demonstrate possible statistically significant correlations between the competencies of social entrepreneurship, complex thinking, and entrepreneurial self-efficacy. The results confirm the correlations between the competencies of social entrepreneurship, complex thinking, and entrepreneurial self-efficacy, concluding that there is statistically significant information to indicate that the complex thinking competency positively impacts not only the process of generating social entrepreneurship projects but also the scaling of entrepreneurs’ perceptions about their capabilities at the time of entrepreneurship. At a practical level, this study presents results that argue for the need to develop complex thinking in students in social entrepreneurship programs, both in universities and in organizations that promote entrepreneurship. It confirms that complex thinking is a valuable competency in the ideation and generation of entrepreneurial proposals

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

© 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
