Challenges and Opportunities in Data Visualization Education: A Call to Action.

This paper is a call to action for research and discussion on data visualization education. As visualization evolves and spreads through our professional and personal lives, we need to understand how to support and empower a broad and diverse community of learners in visualization. Data Visualization is a diverse and dynamic discipline that combines knowledge from different fields, is tailored to suit diverse audiences and contexts, and frequently incorporates tacit knowledge. This complex nature leads to a series of interrelated challenges for data visualization education. Driven by a lack of consolidated knowledge, overview, and orientation for visualization education, the 21 authors of this paper-educators and researchers in data visualization-identify and describe 19 challenges informed by our collective practical experience. We organize these challenges around seven themes People, Goals & Assessment, Environment, Motivation, Methods, Materials, and Change. Across these themes, we formulate 43 research questions to address these challenges. As part of our call to action, we then conclude with 5 cross-cutting opportunities and respective action items: embrace DIVERSITY+INCLUSION, build COMMUNITIES, conduct RESEARCH, act AGILE, and relish RESPONSIBILITY. We aim to inspire researchers, educators and learners to drive visualization education forward and discuss why, how, who and where we educate, as we learn to use visualization to address challenges across many scales and many domains in a rapidly changing world: viseducationchallenges.github.io.

Pentaclethra macroloba: A Review of the Biological, Pharmacological, Phytochemical, Cosmetic, Nutritional and Biofuel Potential of this Amazonian Plant.

Pracaxi (Penthaclethra macroloba (Willd.) Kuntze) is an Amazonian plant, traditionally used by the native population to treat health disorders such as inflammation, erysipelas, wound healing, muscle pain, ear pain, diarrhea, snake and insect bites as well as for cancer treatment. Other common uses include using the oil for frying, skin and hair beautification, and as an alternative source of energy. This review is focused on highlighting its taxonomy, occurrence and botanical origins, popular uses, pharmacology and biological activities, cytotoxicity, biofuel activity and phytochemistry in order to explore future therapeutic use and other applications. Pracaxi contains triterpene saponins, sterols, tannins, oleanolic acid, unsaturated fatty acids and long-chain fatty acids, with a high behenic acid value, which may serve for incorporation into drug delivery systems as well for the development of new drugs. These components are correlated with its anti-inflammatory, antimicrobial, healing, anti-hemolytic, anti-hemorrhagic, antiophidic, and larvicidal activities against Aedes aegypti and Helicorverpa zea, which ratify the popular/traditional uses. The species is nitrogen fixing; it is easy to propagate in floodplains and the terra firma, and it can be used for the reforestation of degraded areas. Additionally, the oil extracted from the seeds can leverage the bioeconomy of the region based on sustainable exploration.

Showing Data About People: A Design Space of Anthropographics.

When showing data about people, visualization designers and data journalists often use design strategies that presumably help the audience relate to those people. The term anthropographics has been recently coined to refer to this practice and the resulting visualizations. Anthropographics is a rich and growing area, but the work so far has remained scattered. Despite preliminary empirical work and a few web essays written by practitioners, there is a lack of clear language for thinking about and communicating about anthropographics. We address this gap by introducing a conceptual framework and a design space for anthropographics. Our design space consists of seven elementary design dimensions that can be reasonably hypothesized to have some effect on prosocial feelings or behavior. It extends a previous design space and is informed by an analysis of 105 visualizations collected from newspapers, websites, and research articles. We use our conceptual framework and design space to discuss trade-offs, common design strategies, as well as future opportunities for design and research in the area of anthropographics.

Physicochemical characterization, fatty acid composition, and thermal analysis of Bertholletia excelsa HBK oil.

The present study aimed at characterizing the oil extracted from Bertholletia excelsa H.B.K. almond, a native species from the Amazon region. Analytical methods used for oils and fats were employed through pharmacopoeia assays, AOCS (American Oil Chemists Society) standard methods as well as those recommended by ANVISA (National Health Surveillance Agency) such as acidity, peroxide value, saponification index, iodine value and refractive index, pH and relative density, and also thermoanalytical analyses (thermogravimetry, differential thermogravimetry and differential thermal analysis) as well as chromatographic analysis (gas chromatography). The characterization assessments of B. excelsa oil showed results indicating that the oil contains polyunsaturated fatty acids in large proportion. The termoanalytical tests indicated that B.excelsa oil showed thermal stability up to 220 °C, These results showed that the oil extracted from B. excelsa has acceptable characteristics and is of good quality.

Extração líquido-líquido de compostos presentes na própolis / Liquid-liquid extraction of propolis compounds

Uma amostra de própolis produzida pela abelha do tipo apis mellifera foi submetida a um processo para extração de alguns compostos farmacologicamente ativos presentes na própolis. Usou-se um extrator líquido-líquido para separação dos compostos, os quais foram identificados por cromatografia líquida de alta eficiência (CLAE). Os compostos analisados foram ácidos fenólicos (p-cumárico e derivados), um flavonóide e um derivado de canferol. O processo de extração permitiu isolar o ácido 3-prenil-4-hidroxicinâmico e o ácido 3,5-diprenil-4-hidroxicinâmico para a fase aquosa ou orgânica, respectivamente.

Cisto peritoneal: relato de um caso / Peritoneal cyst: report of a case

Os autores apresentam um caso de cisto peritonial que ocupava o espaço retroperitonial em um adulto internado no H.U. da UFJF no ano de l986. Destacam a história e incidência, patologia, etiologia e classificaçäo, o diagnóstico, o diagnóstico deferencial, tratamento e prognóstico dessa rara patologia

Proteçäo do miocárdio em cirurgia cardíaca: estudo em parada anóxica e com diferentes soluçöes cardioplégicas / Myocardial protection in cardiac surgery study with anoxic arrest and with different cardioplegic solutions

Os autores realizaram estudo das alteraçöes miocárdicas em cirurgia cardíaca com circulaçäo extracorpórea, sob o aspecto ultraestrutural. Foram estudados 18 cäes, divididos em 3 grupos de 6 animais: Grupo I, parada anóxica hipotérmica; Grupo II, soluçäo de St. Thomas; Grupo III, Soluçäo de Gomes. Os cäes foram anestesiados e submetidos à cirurgia cardíaca com circulaçäo extracorpórea. A técnica empregada foi a usual, com perfusäo hipotérmica e após o clampeamento da aorta no grupo I, manteve-se apenas a parada anóxica e, nos demais, foi infundida a soluçäo cardioplégica de St. Thomas, grupo II, e de Gomes, grupo III. As biópsias foram coletadas em cada cäo, antes e após a parada cardíaca e, após 30 minutos de perfusäo, e enviadas para o Laboratório de Microscopia Eletrônica da UFSM. Os resultados mostraram, no grupo I, severas alteraçöes a nível ultraestrutural com edema intra e extracelular, rotura de miofibrilas e depleçäo de glicogênio. No grupo II observou-se apenas discreto edema intracelular e leve depleçäo de glicogênio, que melhorou após a reperfusäo. No grupo III houve apenas muito leve edema intracelular e depleçäo do glicogênio que regrediram totalmente após a reperfusäo. Os resultados permitiram concluir que as alteraçöes produzidas pela parada anóxica ocorreram mesmo sob hipotermia moderada e foram muito atenuadas pelas soluçöes cardioplégicas, sendo que a de Gomes se revelou um pouco melhor que a de St. Thomas
