“O que é de mulher e o que é de homem”:
Authors: Vieira Norma , Siqueira Deis , Paolo Darcy Di 
Published: April 2020

Este artigo pretende visibilizar a divisão sexual do trabalho e as relações de gênero em diferentes ambientes (terra, água, mangue) utilizados na pesca artesanal em uma comunidade da costa nordeste paraense. O texto ancora-se em entrevistas parcialmente estruturadas, observação participativa e grupos focais. identificou-se uma nítida, mas não inflexível divisão sexual do trabalho e uma rigidez dos lugares de gênero, ou seja, o que é de homem e o que é de mulher. Há trânsitos de ambos entre as atividades, espaços e recursos naturais, mas o que é de homem é sempre mais valorizado na hierarquia das atividades. E há uma inflexibilidade de gênero constituinte: o doméstico é das mulheres. As relações de gênero se ancoram na menor valorização do que é do feminino e no princípio da maternidade e da reprodução como destino das mulheres.

Este artigo analisa alguns casos de devoções não-canônicas no Brasil, Argentina, Chile e Venezuela, com o objetivo de compreender os diversos mecanismos de reparação post-mortem, requisitos para a consagração dos santos populares. Apresenta-se aqui um segmento dos resultados de uma pesquisa etnográfica que originalmente abordou as práticas devocionais e votivas na América do Sul e localizou, entre outras taxonomias, um vigoroso complexo de motivações sociais fundadas na comoção coletiva ante uma morte que, em dada medida, viole ou acentue os vínculos de coesão social. Como resultado, foi possível estabelecer um quadro de referência dinâmico que, ao modo esquemático do “martirológio romano”, situa as motivações devocionais em dois grandes grupos: o de exaltação de virtudes e o da reparação de martírios, lato sensu. Concluiu-se que a matriz religiosa católica, de decisivo impacto na formação da moral sulamericana, imprimiu um modelo de produção de crenças e práticas livremente interpretado pelas populações, e que se renova de acordo com as demandas de cada tempo e espaço.

Internet Programming to Reduce Loneliness and Social Isolation in Aging
Authors: Mullins Lindsay B. , Skemp Lisa , Reed David , Emerson Myra 
Published: April 2020

Loneliness and social isolation in older adults carry mortality risks similar to cigarette smoking. The study aim was to use a Culturally Informed Healthy Aging (CIHA) assessment process in Housing and Urban Development (HUD) communities of older adults (
N
= 262). Through the CIHA assessment process, older adults identified pertinent health problems and the study team developed a health intervention, an Internet Information Station (IIS). The IIS pilot study included computer lesson participation (
n
= 261), written feedback (
n
= 42), and the revised University of California, Los Angeles (R-UCLA) Loneliness Scale (
n
= 11). Increased confidence with technology and connectedness were reported, and a significant difference in “There is no one I can turn to” was observed (IIS compared to non-IIS). The IIS remains an active site for interaction 1-year post intervention. These pilot results supplement the research on older adult engagement in problem identification, intervention design, and outcomes measurement.

Target:
Older adults living in HUD communities.

Intervention Description:
Through CIHA assessment, health problems were identified, and the IIS was developed and implemented.

Mechanisms of Action:
Lessons were developed (e.g., computer basics, connecting with technology, open forum) and evaluated. Pre and post lesson, the R-UCLA Loneliness Scale measured social isolation and loneliness.

Outcomes:
Older adults were engaged in problem identification, program development, and implementation. Feelings of connectedness improved; however, program evaluation with the R-UCLA scale was difficult to obtain.

Trainee and Program Director Perspectives on Meaningful Patient Attribution and Clinical Outcomes Data
Authors: Rosenbluth Glenn , Tong Michelle S. , Montes Shivany Y. Condor , Boscardin Christy 
Published: April 2020

ABSTRACT

Background
The Accreditation Council for Graduate Medical Education specifies that trainees must receive clinical outcomes and quality benchmark data at specific levels related to institutional patient populations. Program directors (PDs) are challenged to identify meaningful data and provide them in formats acceptable to trainees.

Objective
We sought to understand what types of patients, data/metrics, and data delivery systems trainees and PDs prefer for supplying trainees with clinical outcomes data.

Methods
Trainees (n = 21) and PDs (n = 12) from multiple specialties participated in focus groups during academic year 2017–2018. They described key themes for providing clinical outcomes data to trainees.

Results
Trainees and PDs differed in how they identified patients for clinical outcomes data for trainees. Trainees were interested in encounters where they felt a sense of responsibility or had autonomy/independent decision-making opportunities, continuity, or learned something new; PDs used broader criteria including all patients cared for by their trainees. Both groups thought trainees should be given trainee-level metrics and consistently highlighted the importance of comparison to peers and/or benchmarks. Both groups found value in “push” and “pull” data systems, although trainees wanted both, while PDs wanted one or the other. Both groups agreed that trainees should review data with specific faculty. Trainees expressed concern about being judged based on their patients' clinical outcomes.

Conclusions
Trainee and PD perspectives on which patients they would like outcomes data for differed, but they overlapped for types of metrics, formats, and review processes for the data.
Disdrometer measurements under Sense-City rainfall simulator

Published: April 2020

Abstract. The Hydrology, Meteorology and Complexity Laboratory of École des Ponts ParisTech (http://hmco.enpc.fr, last access: 24 March 2020) and the Sense-City consortium (http://sense-city.ifsttar.fr/, last access: 24 March 2020) made available a dataset of optical disdrometer measurements stemming from a campaign that took place in September 2017 under the rainfall simulator of the Sense-City climatic chamber, which is located near Paris. Two OTT Parsivel2 disdrometers were used. The size and velocity of drops falling through the sampling area of the devices of roughly a few tens of square centimetres are computed by disdrometers. This enables the estimation of the drop size distribution and the further study of rainfall microphysics or kinetic energy for example. Raw data – basically a matrix containing a number of drops according to classes of size and velocity, along with more aggregated ones such as rain rate and drop size distribution with filtering – are available. The dataset is publicly available at https://doi.org/10.5281/zenodo.3347051(Gires et al., 2019).
The Matter of Facts
Authors: Leng Gareth , Leng Rhodri Ivor 
Published: April 2020

How biases, the desire for a good narrative, reliance on citation metrics, and other problems undermine confidence in modern science.
Modern science is built on experimental evidence, yet scientists are often very selective in deciding what evidence to use and tend to disagree about how to interpret it. In The Matter of Facts, Gareth and Rhodri Leng explore how scientists produce and use evidence. They do so to contextualize an array of problems confronting modern science that have raised concerns about its reliability: the widespread use of inappropriate statistical tests, a shortage of replication studies, and a bias in both publishing and citing “positive” results. Before these problems can be addressed meaningfully, the authors argue, we must understand what makes science work and what leads it astray.
The myth of science is that scientists constantly challenge their own thinking. But in reality, all scientists are in the business of persuading other scientists of the importance of their own ideas, and they do so by combining reason with rhetoric. Often, they look for evidence that will support their ideas, not for evidence that might contradict them; often, they present evidence in a way that makes it appear to be supportive; and often, they ignore inconvenient evidence.
In a series of essays focusing on controversies, disputes, and discoveries, the authors vividly portray science as a human activity, driven by passion as well as by reason. By analyzing the fluidity of scientific concepts and the dynamic and unpredictable development of scientific fields, the authors paint a picture of modern science and the pressures it faces.
Keep Calm and Log On
Authors: Andrews Gillian "Gus" 
Published: April 2020

How to survive the digital revolution without getting trampled: your guide to online mindfulness, digital self-empowerment, cybersecurity, creepy ads, trustworthy information, and more.
Feeling overwhelmed by an avalanche of online content? Anxious about identity theft? Unsettled by the proliferation of fake news? Welcome to the digital revolution. Wait—wasn't the digital revolution supposed to make our lives better? It was going to be fun and put the world at our fingertips. What happened? Keep Calm and Log On is a survival handbook that will help you achieve online mindfulness and overcome online helplessness—the feeling that tech is out of your control—with tips for handling cybersecurity, creepy ads, untrustworthy information, and much more.
Taking a cue from the famous World War II morale-boosting slogan (“Keep Calm and Carry On”), Gus Andrews shows us how to adapt the techniques our ancestors used to survive hard times, so we can live our best lives online. She explains why media and technology stress us out, and offers empowering tools for coping. Mindfulness practices can help us stay calm and conserve our attention purposefully. Andrews shares the secret of understanding our own opinions'' “family trees” in order to identify misleading “fake news.” She provides tools for unplugging occasionally, overcoming feelings that we are “bad at technology,” and taking charge of our security and privacy. Andrews explains how social media algorithms keep us from information we need and why “creepy ads” seem to follow us online. Most importantly, she urges us to work to rebuild the trust in our communities that the internet has broken.

Published: April 2020

Background
Medulloblastoma (MB) is the most common intracranial malignant tumor in children. The genes and pathways involved in the pathogenesis of MB are relatively unknown. We aimed to identify potential biomarkers and small-molecule drugs for MB.

Methods
Gene expression profile data sets were obtained from the Gene Expression Omnibus (GEO) database and the differentially expressed genes (DEGs) were identified using the Limma package in R. Functional annotation, and cell signaling pathway analysis of DEGs was carried out using DAVID and Kobas. A protein-protein interaction network was generated using STRING. Potential small-molecule drugs were identified using CMap.

Result
We identified 104 DEGs (29 upregulated; 75 downregulated). Gene ontology analysis showed enrichment in the mitotic cell cycle, cell cycle, spindle, and DNA binding. Cell signaling pathway analysis identified cell cycle, HIF-1 signaling pathway, and phospholipase D signaling pathway as key pathways. SYN1, CNTN2, FAIM2, MT3, and SH3GL2 were the prominent hub genes and their expression level were verified by RT-qPCR. Vorinostat, resveratrol, trichostatin A, pyrvinium, and prochlorperazine were identified as potential drugs for MB. The five hub genes may be targets for diagnosis and treatment of MB, and the small-molecule compounds are promising drugs for effective treatment of MB.

Conclusion
In this study we obtained five hub genes of MB, SYN1, CNTN2, FAIM2, MT3, and SH3GL2 were confirmed as hub genes. Meanwhile, Vorinostat, resveratrol, trichostatin A, pyrvinium, and prochlorperazine were identified as potential drugs for MB.
