Análise de pôsteres realizados durante uma atividade de ensino de física com enfoque CTS

Este trabalho apresenta a análise de alguns pôsteres confeccionados por estudantes do Ensino Médio durante uma atividade de ensino de Física com enfoque CTS que explorou a temática da produção de movimento por alguns meios de transporte. O objetivo da pesquisa é buscar elementos nestes materiais que permitam inferir como o enfoque CTS da atividade repercutiu nas produções dos estudantes. A metodologia da pesquisa é qualitativa, do tipo documental e utiliza procedimentos analíticos da análise de conteúdo. A amostra consistiu em 14 pôsteres que representavam explicações para o movimento de vários meios de transporte, como bicicleta, avião, skate, etc., e em anotações realizadas pelo pesquisador no momento de apresentação dos trabalhos. Como resultado, percebeu-se que as produções valorizaram os aspectos tecnológicos prioritariamente, seguidos por considerações de aspectos históricos e sociais vincula-dos aos meios de transporte escolhidos. Paralelamente, percebeu-se indícios de que o enfoque CTS da atividade provocou nos estu-dantes a necessidade de ampliação do conhecimento acerca de aspectos mais fundamentais de ciência e tecnologia

Twenty-three unsolved problems in hydrology (UPH) – a community perspective

This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through on-line media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focussed on process-based understanding of hydrological variability and causality at all space and time scales. Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come

ESHRE good practice recommendations for add- ons in reproductive medicine

The draft of the paper “ESHRE Good practice recommendations for add-ons in reproductive medicine” was published for public review for 4 weeks, between 1 November and 1 December 2022. This report summarizes all reviewers, their comments and the reply of the working group and is published on the ESHRE website as supporting documentation to the paper. During the stakeholder review, a total of 274 comments (including 24 duplicates) were received from 46 reviewers. Reviewers included professionals and representatives of donor-conceived offspring organisations. The comments were focussed on the content of the guideline (209 comments), language and style (31 comments), or were remarks that did not require a reply (10 comments). All comments to the language and format were checked and corrected where relevant. The comments to the content of the paper (n=209) were assessed by the working group and where relevant, adaptations were made in the paper (n=94; 45%). Adaptations included revisions and/or clarifications of the text, and amendments to the recommendations. For a number of comments, the working group considered them outside the scope of the paper or not appropriate/relevant (n=115; 55%).peer-reviewe

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Dimensões ambientais em uma sequência de ensino de Física CTSA

The present work presents an analysis which is based on some results from a teaching expe­rience involving the issue of mass transportation. Such activity integrated a lesson sequence of Physics with a STSE approach (Science, Technology, Society and Environment) whose theme was ‘Transport Phenomena’. The main objective of the work is to contribute to the de­bate regarding the potential of scientific education in promoting citizenship education linked to environmental issues. Sixty students from a high school integrated with professional education participated in the study. The data consisted of the written productions by the students during the investigation of the presented problem. The collected data were analyzed through content analysis. The results highlighted the fact that the students considered broad dimensions of the issue in focus, giving evidence of the production of understandings that took into account several perspectives of the complex relationship between humanity and the environment.Este trabalho apresenta uma análise que tem como base alguns resultados advindos de uma atividade de ensino que envolvia a problemática dos transportes em massa.
