Introdução ao estudo do movimento e análise de gráficos mediada por um jogo virtual de tabuleiro

Technological advances in the last decades have demanded new ways of teaching at different levels. In this way, we present, analyze and discuss the possibilities in applying a proposal of didactic material that we developed to be used with students in the final years of elementary school II and high school. The material is composed of a virtual board game and software developed in Python that allows the organization and analysis of the game’s data. The material, of a ludic and technological nature, allows study concepts related to the movement of an object, such as position, classification of its movement velocity. This study is executed through the analysis of the data generated by each student in the board game and plotted in graphs of position and velocity, both versus time. The platform is intuitive, relatively simple to use and shows the potential to contribute to the teaching process in a more meaningful context, allowing students to be more engaged and concreteness about the topic.Os avanços tecnológicos observado nas últimas décadas têm demandado novas formas de se praticar o ensino em seus diferentes níveis. Nessa linha, apresentamos, analisamos e discutimos as possibilidades de aplicação em sala de aula de uma proposta de material didático que desenvolvemos e que pode ser usado junto a estudantes dos anos finais do ensino fundamental II e do ensino médio. O material é composto por um jogo de tabuleiro virtual e um software desenvolvido em Python que permite a organização e análise dos dados obtidos à medida que o jogo acontece. O material, de cunho lúdico e tecnológico, permite que sejam explorados junto aos estudantes conceitos relacionados ao movimento de um corpo como, por exemplo, posição, classificação do movimento e velocidade média. Esse estudo é realizado através da análise dos dados relacionados ao desempenho de cada estudante no jogo de tabuleiro a partir de gráficos da posição e da velocidade média entre duas jogadas consecutivas, ambos versus o tempo. A plataforma proposta é intuitiva, de relativa simples utilização e tem potencial para contribuir para com o processo de ensino do tópico aqui explorado em um contexto de maior significação, permitindo aos estudantes maior engajamento e concretização acerca do tema

Literature overview highlights lack of paediatric donation protocols but identifies common themes that could guide their development

Aim: Paediatric donation is a unique and extremely sensitive process that requires specific knowledge and competencies. Most countries use protocols for organ and tissue donation to ensure optimal care for the donor and family, but these mainly focus on adults. However, the donation process for children differs from adults in many ways. An overview of the literature was performed to identify protocols for the paediatric population. Methods: PubMed, Web of Science, EMBASE and the Internet were searched up to March 2016 for papers or other sources in English related to specific organ and tissue donation protocols for children and neonates. This comprised title, abstract and then full-text screening of relevant data. Results: We included 12 papers and two electronic sources that were mainly from North America and Europe. Most discussed donations after cardiac death. The recurring themes included identifying potential donors, approaching parents, palliative care and collaboration with organ procurement organisations. Most papers called for paediatric donation policies to be standardised. Conclusion: Scientific publications in English on paediatric donation protocols are very scarce. No comprehensive paediatric donation protocol was found. We identified several recurring themes in the literature that could be used to develop such protocols

Evolving and Sustaining Ocean Best Practices to Enable Interoperability in the UN Decade of Ocean Science for Sustainable Development

The UN Decade of Ocean Science for Sustainable Development (Ocean Decade) challenges marine science to better inform and stimulate social and economic development while conserving marine ecosystems. To achieve these objectives, we must make our diverse methodologies more comparable and interoperable, expanding global participation and foster capacity development in ocean science through a new and coherent approach to best practice development. We present perspectives on this issue gleaned from the ongoing development of the UNESCO Intergovernmental Oceanographic Commission (IOC) Ocean Best Practices System (OBPS). The OBPS is collaborating with individuals and programs around the world to transform the way ocean methodologies are managed, in strong alignment with the outcomes envisioned for the Ocean Decade. However, significant challenges remain, including: (1) the haphazard management of methodologies across their lifecycle, (2) the ambiguous endorsement of what is "best" and when and where one method may be applicable vs. another, and (3) the inconsistent access to methodological knowledge across disciplines and cultures. To help address these challenges, we recommend that sponsors and leaders in ocean science and education promote consistent documentation and convergence of methodologies to: create and improve context-dependent best practices; incorporate contextualized best practices into Ocean Decade Actions; clarify who endorses which method and why; create a global network of complementary ocean practices systems; and ensure broader consistency and flexibility in international capacity development

Relative effectiveness and safety of pharmacotherapeutic agents for patent ductus arteriosus (PDA) in preterm infants: A protocol for a multicentre comparative effectiveness study (CANRxPDA)

Introduction Patent ductus arteriosus (PDA) is the most common cardiovascular problem that develops in preterm infants and evidence regarding the best treatment approach is lacking. Currently available medical options to treat a PDA include indomethacin, ibuprofen or acetaminophen. Wide variation exists in PDA treatment practices across Canada. In view of this large practice variation across Canadian neonatal intensive care units (NICUs), we plan to conduct a comparative effectiveness study of the different pharmacotherapeutic agents used to treat the PDA in preterm infants. Methods and analysis A multicentre prospective observational comparative-effectiveness research study of extremely preterm infants born 29 weeks gestational age with an echocardiography confirmed PDA will be conducted. All participating sites will self-select and adhere to one of the following primary pharmacotherapy protocols for all preterm babies who are deemed to require treatment. Standard dose ibuprofen (10 mg/kg followed by two doses of 5 mg/kg at 24 hours intervals) irrespective of postnatal age (oral/intravenous). Adjustable dose ibuprofen (oral/intravenous) (10 mg/kg followed by two doses of 5 mg/kg at 24 hours intervals if treated within the first 7 days after birth. Higher doses of ibuprofen up to 20 mg/kg followed by two doses of 10 mg/kg at 24 hours intervals if treated after the postnatal age cut-off for lower dose as per the local centre policy). Acetaminophen (oral/intravenous) (15 mg/kg every 6 hours) for 3-7 days. Intravenous indomethacin (0.1-0.3 mg/kg intravenous every 12-24 hours for a total of three doses). Outcomes The primary outcome is failure of primary pharmacotherapy (defined as need for further medical and/or surgical/interventional treatment following an initial course of pharmacotherapy). The secondary outcomes include components of the primary outcome as well as clinical outcomes related to response to treatment or adverse effects of treatment. Sites and sample size The study will be conducted in 22 NICUs across Canada with an anticipated enrollment of 1350 extremely preterm infants over 3 years. Analysis To examine the relative effectiveness of the four treatment strategies, the primary outcome will be compared pairwise between the treatment groups using χ 2 test. Secondary outcomes will be compared pairwise between the treatment groups using χ 2 test, Student\u27s t-test or Wilcoxon rank sum test as appropriate. To further examine differences in the primary and secondary outcomes between the four groups, multiple logistic or linear regression models will be applied for each outcome on the treatment groups, adjusted for potential confounders using generalised estimating equations to account for within-unit-clustering. As a sensitivity analysis, the difference in the primary and secondary outcomes between the treatment groups will also be examined using propensity score method with inverse probability weighting approach. Ethics and dissemination The study has been approved by the IWK Research Ethics Board (#1025627) as well as the respective institutional review boards of the participating centres. © 2021 Author(s).

Effects of exercise on stress : a meta-analysis

Physical exercise is frequently prescribed by clinicians and researchers as an effective stress reduction technique. There has been some research to support this assertion, however the research has been varied in its methodological rigor. The design problems, variations in exercise programs, and the use of a wide range of psychological measures have made results difficult to interpret. Additionally, the psychological benefits and underlying change processes have not been clearly delineated. The purpose of this study was to conduct a meta-analysis of the research in this area in an attempt to answer specific questions regarding the role of exercise in stress reduction. This meta-analytic approach was chosen because it permits the quantitative integration of findings of several studies and consideration of the variables that may influence the variance in study outcomes. The effectiveness of exercise as a treatment for stress, the type of exercise that was most beneficial, and the type of individual who gained the most from the exercise intervention was examined. The 61 effect sizes, which were calculated from 24 studies included in the meta-analysis, were coded along with other variables considered important. Study components such as design type, stress level, type of exercise program, program length, frequency of exercise sessions, attrition rate, psychological measure, composition of sample, gender, and study type were coded as independent variables. Effect size was the dependent variable. Analysis of variance revealed that exercise was an effective stress reducer, stressed people gained a greater stress reduction effect than minimally stressed people, and there were no differences between trait and state anxiety reduction from pre- to post-exercise program. In addition, a one-way ANOVA indicated that there was a significant difference between program lengths. Examination of the means revealed that an 8- to 12-week program was most effective in reducing stress. Although there was a greater effect size for unpublished studies than published studies, the pattern of change for each study type was similar. The significance of these results and recommendations for future studies are discussed.Education, Faculty ofCurriculum and Pedagogy (EDCP), Department ofGraduat

Shifting Gears : Stadium Road Neighbourhood as a Leader in Connectivity

The University of British Columbia is a leading institution in creating a place where students, faculty, and staff can live, work, play, learn, and interact. With their vision of creating a sustainable campus that promotes both community and environmental health, transportation is one of the key elements that needs to be addressed to meet their listed targets and goals. UBC is a proven regional trendsetter in sustainable transportation, which makes the university responsible for moving the agenda forward. As a result, the Shifting Gears provides a prime opportunity to plan a neighbourhood that supports the university’s existing values through a transportation and connectivity lens. Transportation and connectivity in this project entails fostering safe, efficient, and innovative connections that promote active and public modes of transportation to, from, and within the Stadium Road Neighbourhood. As a neighbourhood that is in its initial planning stages, this project was approached in a way to present comprehensive recommendations that respond to the campus’ existing conditions and needs. Therefore, this project includes a thorough review of existing campus policies and existing transportation conditions that led to the creation of a needs assessment to respond to the existing gaps in campus transportation. Given the scope of the project, these needs were addressed in four main focus areas near or within the site where interventions for transportation and connectivity can have the biggest impact. These areas include East Mall, West 16th, parking for the site, and neighbourhood movement design. Several different interventions were evaluated based on the project objectives, and the best performing intervention for each focus area was chosen and presented as our final recommendation. These recommendations support the current transportation values and behaviours of the potential SRN users while also promoting and accommodating a future where innovative and sustainable transportation technologies and designs become the norm at UBC.

Effects of mixing alcohol with energy drink on objective and subjective intoxication : Results from a Dutch on-premise study

Background: The purpose of this on-premise study was to determine if alcohol mixed with energy drink (AMED) consumption masks the subjective feelings of intoxication when compared to consuming alcohol only. Methods: The study was conducted on five nights in the city center of Utrecht. N∈=∈997 people leaving bars were interviewed about their alcohol consumption with and without energy drinks, for that particular evening and for other occasions. People reporting drug and medication use were excluded (N∈=∈84). Subjective intoxication was rated on a 10-point scale. Objective intoxication (breath alcohol concentration, BrAC) was determined with a breath alcohol test. Three groups were identified: (1) the AMED-tonight group (N∈=∈185, 20.2 %), (2) the AMED-other-nights group (N∈=∈246, 27.1 %), and (3) the no-AMED group (N∈=∈482, 52.7 %). Results: Objective intoxication (BrAC) did not significantly differ (p∈=∈0.94) between the AMED-tonight group (0.074 %∈±∈0.05), AMED-other-nights group (0.073 %∈±∈0.05), and the no-AMED group (0.074 %∈±∈0.05). In line, subjective intoxication was not significantly different (p∈=∈0.96) between the AMED-tonight group (4.5∈±∈2.2), AMED-other-nights group (4.6∈±∈2.3), and no-AMED group (4.6∈±∈2.2). Within-subjects comparisons revealed no significant differences in total alcohol consumption between AMED occasions and alcohol only occasions. Regression analyses showed that "gender" (beta∈=∈0.078, p∈=∈0.016), "time of testing" (beta∈=∈0.085, p∈=∈0.009,) and "BrAC" (beta∈=∈0.574, p∈=∈0.0001) together explained 37.7 % of variance of subjective intoxication scores (Cohen's f 2∈=∈0.605). Whether or not subjects consumed energy drinks did not predict subjective intoxication scores. Conclusion: The data suggests that mixing alcohol with energy drink does not mask subjective intoxication
