Abstract
BackgroundDespite a significant shortage of psychiatrists in China, an ever-increasing amount of psychiatrists in China are experiencing burnout and job dissatisfaction and considering leaving their jobs. Yet, to our knowledge, there have been no nationwide studies to date that examined both burnout and job dissatisfaction of psychiatrists in China. Therefore, this study evaluated burnout and job dissatisfaction of psychiatrists in China, and identified relevant characteristics. MethodsWe conducted a nationwide, cross-sectional survey in March 2019. Psychiatrists from all tertiary psychiatric hospitals in China were invited to participate. The Maslach Burnout Inventory-Human Service Survey and the short version of the Minnesota Satisfaction Questionnaire were used to measure burnout and job satisfaction. Data on socio-demographic and occupational characteristics were collected. Multivariate logistic regression was conducted to identify socio-demographic and occupational characteristics associated with burnout and job satisfaction.ResultsIn total, 4520 psychiatrists from tertiary psychiatric hospitals in China completed the questionnaire. Overall, 38.4% of respondents met the criteria for burnout and 35.6% were dissatisfied with their jobs. Being male, more years of practice, having no leadership role, and longer working hours per week were significantly associated with burnout and job dissatisfaction. Lower monthly pay was significantly associated with job dissatisfaction but not burnout. Moreover, burnout was significantly associated with job dissatisfaction.ConclusionsOur data suggest a high rate of burnout and job dissatisfaction among psychiatrists in China. In order to preserve and strengthen the mental health workforce, proactive measures are urgently needed to improve job morale of psychiatrists in China.

Abstract
Core-shell structured NiCo2S4@NiMoO4 is considered to be one of the most promising electrode materials for supercapacitors due to its high specific capacitance and excellent cycle performance. In this work, we report NiCo2S4@NiMoO4 nanosheets on Ni foam by two-step fabricated method. The as-obtained product has high capacitance of 1102.5 F g− 1 at 1 A g− 1. The as-assembled supercapacitor has also a high energy density of 37.6 W h kg− 1 and superior cycle performance with 85% capacitance retention. The electrode materials reported here might exhibits potential applications in future energy storage devices.
Simulating the global economic ripples after a major hurricane — the case of Hurricane Sandy

Published: June 2021

Abstract
Tropical cyclones range among the most severe disasters on Earth. Their economic repercussions along the supply and trade network also affect remote economies that are not directly affected. To find these repercussions in data is challenging due to the strong volatility of economic interactions. Numerical simulations can help to identify these ripples by approaching the problem from an exploratory angle isolating the effect of interest. We here simulate possible global repercussions for the example case of Hurricane Sandy (2012) using the shock-propagation model Acclimate. It models the behaviour of over 7,000 regional economic sectors, interlinked through about 1.8 million trade relations. The modeled shock yields a global three-phase ripple: an initial demand reduction and price decrease, followed by a supply shortage with increasing prices, and finally a recovery phase. Regions with strong trade relations to the US experience stronger magnitudes of the ripple. A dominating demand reduction or supply shortage leads to overall consumption gains or losses of a region, respectively. Throughout the three phases the model suggests overall a global consumption loss (~ 0.03%) with the strongest impact onto the US itself (~ 0.14%).

Abstract
There are no published data on the detection of tube agglutination (TA) 37°C-onJy antibodies by solid-phase (SP) red celi adherence assays using anti-IgG-coated indicator red cells. Thirteen examples of TA 37°C-only antibodies were tested by conventional SP methods. Four TA 37°C-only antibodies failed to react by SP. Three were anti-Lea considered clinically insignificant, and one was anti-E, an antibody of potential clinical significance. The remaining nine TA 37°C-only antibodies reacted by SP, including three anti-c, two anti-D, two anti-E, one anti-N. and one anti-M. The anti-M reacted with indicator red cells that lacked the red cell antigen and failed to react with IgG-coated indicator red cells whose anti-IgG component had been neutralized, indicating the antibody contained an IgG component. Two anti-D and one anti-c continued to react in an SP test using neutralized anti-IgG antigen-positive indicator red cells, i.e., indicator binding independent of antiglobulin, suggesting an IgM nature to these antibodies. Therefore, many TA 37°C-oniy antibodies can be detected by SP either through detection of an IgG component by the anti-IgG of the indicator red cells, or through IgM crosslinking of antigen-positive indicator red cells to antigen-positive SP reagent red cell membranes.

Published: June 2021

Abstract
Extraction of eggs of Meloidogyne spp. in sodium hypochlorite (NaOCl) is a helpful procedure to assess the population levels and to obtain inoculum. In this sense, laboratory and greenhouse experiments were done to evaluate the effect of the NaOCl concentration on the viability of M. enterolobii eggs. Additionally, the objective of this investigation was to corroborate the preferable treatments to count populations in cucumber galled roots or to obtain inoculum of M. enterolobii. It was shown that the effect of the NaOCl concentration on the viability of M. enterolobii eggs is potentially detrimental. The NaOCl concentration caused a higher hatching, which in turn, resulted in non-infective larvae. Therefore, the best treatments to obtain inoculum of eggs of M. enterolobii included the 0.75% NaOCl (with 8-min stirring), 0.5% NaOCl (with stirring for 8, 12, and 16 min), and 0.3% NaOCl concentration (with stirring for 8, 12, 16, and 20 min). For a correct estimate of the egg population in roots, we show by several treatments that a concentration of 0.5% NaOCl (with stirring for 8, 12, and 16 min) and 0.75% NaOCl (with 8-min stirring) give the highest results.

Published: June 2021

Esta investigação tem o objetivo de analisar se as tomadas de decisões nas execuções orçamentárias no município de São Paulo, no período de 2002 a 2019, foram realizadas com base em processos incrementais (estabilidade) ou pontuados com o suporte da Teoria do Equilíbrio Pontuado (PET). As análises foram realizadas com os dados atualizados para o dia 31 de março de 2020. Os Testes de Kolmogorov-Smirnov e Shapiro-Wilk foram utilizados para testar a normalidade ou não das variações das execuções orçamentárias. Os resultados apontaram que as tomadas de decisões nas execuções orçamentárias no município de São Paulo da receita e despesa total ocorreram com base em processos incrementais (estabilidade). A execução das despesas por funções de governo (Legislativa, Judiciária, Administração, Educação, Saúde etc.) ocorreram com base em processos pontuados (atípicos). O estudo corrobora com a utilização do suporte da Teoria do Equilíbrio Pontuado (PET) nas análises da política orçamentária nos municípios brasileiros. Conclui-se que os orçamentos da Prefeitura de São Paulo são elaborados de forma incremental, mas suas execuções têm padrão de estabilidade com interrupções (pontuações). A pesquisa contribui para o avanço da literatura nas análises sobre a execução da política orçamentária de forma teórica e prática. A abordagem metodológica poderá ser utilizada por outros pesquisadores como orientação e estímulo para outras pesquisas similares. Pode-se afirmar que, do ponto de vista social, os resultados desta investigação podem ser utilizados pelos formuladores de política orçamentária e como forma de reduzir as assimetrias de informação sobre a gestão orçamentária para os cidadãos.
Estimation of COVID-19 Period Prevalence and the Undiagnosed Population in Canadian Provinces: Model-Based Analysis

Published: June 2021

Background
The development of a successful COVID-19 control strategy requires a thorough understanding of the trends in geographic and demographic distributions of disease burden. In terms of the estimation of the population prevalence, this includes the crucial process of unravelling the number of patients who remain undiagnosed.

Objective
This study estimates the period prevalence of COVID-19 between March 1, 2020, and November 30, 2020, and the proportion of the infected population that remained undiagnosed in the Canadian provinces of Quebec, Ontario, Alberta, and British Columbia.

Methods
A model-based mathematical framework based on a disease progression and transmission model was developed to estimate the historical prevalence of COVID-19 using provincial-level statistics reporting seroprevalence, diagnoses, and deaths resulting from COVID-19. The framework was applied to three different age cohorts (< 30; 30-69; and ≥70 years) in each of the provinces studied.

Results
The estimates of COVID-19 period prevalence between March 1, 2020, and November 30, 2020, were 4.73% (95% CI 4.42%-4.99%) for Quebec, 2.88% (95% CI 2.75%-3.02%) for Ontario, 3.27% (95% CI 2.72%-3.70%) for Alberta, and 2.95% (95% CI 2.77%-3.15%) for British Columbia. Among the cohorts considered in this study, the estimated total number of infections ranged from 2-fold the number of diagnoses (among Quebecers, aged ≥70 years: 26,476/53,549, 49.44%) to 6-fold the number of diagnoses (among British Columbians aged ≥70 years: 3108/18,147, 17.12%).

Conclusions
Our estimates indicate that a high proportion of the population infected between March 1 and November 30, 2020, remained undiagnosed. Knowledge of COVID-19 period prevalence and the undiagnosed population can provide vital evidence that policy makers can consider when planning COVID-19 control interventions and vaccination programs.
Forecasting the COVID-19 Epidemic By Integrating Symptom Search Behavior Into Predictive Models: Infoveillance Study
Authors: Rabiolo Alessandro , Alladio Eugenio , Morales Esteban , McNaught Andrew Ian , Bandello Francesco , Afifi Abdelmonem A , Marchese Alessandro 
Published: June 2021

Background
Previous studies have suggested associations between trends of web searches and COVID-19 traditional metrics. It remains unclear whether models incorporating trends of digital searches lead to better predictions.

Objective
The aim of this study is to investigate the relationship between Google Trends searches of symptoms associated with COVID-19 and confirmed COVID-19 cases and deaths. We aim to develop predictive models to forecast the COVID-19 epidemic based on a combination of Google Trends searches of symptoms and conventional COVID-19 metrics.

Methods
An open-access web application was developed to evaluate Google Trends and traditional COVID-19 metrics via an interactive framework based on principal component analysis (PCA) and time series modeling. The application facilitates the analysis of symptom search behavior associated with COVID-19 disease in 188 countries. In this study, we selected the data of nine countries as case studies to represent all continents. PCA was used to perform data dimensionality reduction, and three different time series models (error, trend, seasonality; autoregressive integrated moving average; and feed-forward neural network autoregression) were used to predict COVID-19 metrics in the upcoming 14 days. The models were compared in terms of prediction ability using the root mean square error (RMSE) of the first principal component (PC1). The predictive abilities of models generated with both Google Trends data and conventional COVID-19 metrics were compared with those fitted with conventional COVID-19 metrics only.

Results
The degree of correlation and the best time lag varied as a function of the selected country and topic searched; in general, the optimal time lag was within 15 days. Overall, predictions of PC1 based on both search terms and COVID-19 traditional metrics performed better than those not including Google searches (median 1.56, IQR 0.90-2.49 versus median 1.87, IQR 1.09-2.95, respectively), but the improvement in prediction varied as a function of the selected country and time frame. The best model varied as a function of country, time range, and period of time selected. Models based on a 7-day moving average led to considerably smaller RMSE values as opposed to those calculated with raw data (median 0.90, IQR 0.50-1.53 versus median 2.27, IQR 1.62-3.74, respectively).

Conclusions
The inclusion of digital online searches in statistical models may improve the nowcasting and forecasting of the COVID-19 epidemic and could be used as one of the surveillance systems of COVID-19 disease. We provide a free web application operating with nearly real-time data that anyone can use to make predictions of outbreaks, improve estimates of the dynamics of ongoing epidemics, and predict future or rebound waves.

Published: June 2021

Electric and magnetic fields (EMFs) are indefinable regions of energy that are often referred to as Radiation and are linked to the use of electricity as well as various natural and man-made phenomena. Due to continuous exposure to Unexplained and negative EMF, people experienced stress, anxiety, Hypoxia, and even long-term exposure result in Cancer to patients. On the other hand, Rudraksha seeds are globally known as electromagnetic seeds due to their positive electromagnetic healing effect. This research was conducted to find the consequence of the Negative EMF effect on human pulse rate and Oxygen carrying capacity in blood and the use of Rudraksha to study cut off harmful effect of negative EMF by this Electromagnetic property. This topic constitutes a new domain with the largely unstudied potential of Rudraksha seeds shielding effect on Unexplained Negative Electromagnetic Radiation.

Authors: Shuster Shirley , Vlasschaert Caitlyn , Awad Sara 
Published: June 2021

Thyrotoxic periodic paralysis (TPP) is characterized by muscle weakness, areflexia, and hypokalemia in the setting of thyrotoxicosis. We present the case of a 32-year-old male with multiple presentations to the emergency department for lower limb weakness, tremors, diaphoresis, and tachycardia. His initial blood work revealed T3-toxicosis and hypokalemia, and he was treated for TPP with intravenous fluids and potassium supplementation. He had been ingesting weight loss supplements containing iodine, kelp, licorice, and likely undeclared thyroid hormones or mimics. Following discontinuation of supplements, all laboratory investigations normalized and thyrotoxicosis symptoms resolved. This case illustrates that ingestion of thyroid hormone-based nutraceuticals should be considered as a cause of thyrotoxicosis and TPP.
RésuméLa paralysie périodique thyréotoxique (PPT) se caractérise par de la faiblesse musculaire, une aréflexie et une hypokaliémie dans le contexte de la thyréotoxicose. Nous exposons le cas d’un homme de 32 ans qui s’est présenté au service des urgences pour de multiples symptômes, soit une faiblesse des membres inférieurs, des tremblements, une diaphorèse et une tachycardie. Son bilan sanguin initial a révélé une toxicose-T3 et une hypokaliémie, et il a été traité contre la PPT par des solutés intraveineux et une recharge en potassium. Il ingérait des suppléments pour la perte de poids contenant de l’iode, de la laminaire, de la réglisse et probablement des hormones thyroïdiennes ou leurs analogues non déclarés. Après l’arrêt des suppléments, tous les examens de laboratoire sont revenus à la normale et les symptômes de thyréotoxicose ont disparu. Ce cas montre que l’ingestion de nutraceutiques à base d’hormones thyroïdiennes devrait être considérée comme une cause de la thyréotoxicose et de la PPT.
O Ruído que Brota dos Muros do Porto: Ensaio visual sobre o direito à habitação
Authors: Barbosa Inês 
Published: June 2021

Enquadrado numa sociologia visual e andante, este ensaio apresenta e discute uma seleção de fotografias de protesto pelo direito à habitação, capturadas nas paredes do Porto, Portugal, nos últimos dois anos. As imagens dão conta das tensões e contradições associadas aos processos de gentrificação e turistificação. Desse conjunto, salienta-se a diversidade de agentes, linguagens, destinatários ou estratégias discursivas, bem como o potencial de disseminação que estas mensagens possuem, ao serem transpostas para outros contextos, como as mobilizações coletivas ou as redes sociais. Destaca-se ainda o seu carácter duplo de inscrição no espaço público: são memória de reivindicações passadas e incentivo para lutas futuras. Sendo aparentemente silenciosas, estas contra-visualidades produzem ruído, modificando a paisagem urbana e provocando transformações sociais e políticas.Palavras-chave: fotografia, protesto, gentrificação Framed in a visual and walking sociology, this essay presents and discusses a selection of photographs of protest for the right to housing, captured on the walls of Porto, Portugal, in the last two years. The images show the tensions and contradictions associated with the processes of gentrification and tourism. Of this set, we highlight the diversity of agents, languages, recipients or discursive strategies, as well as the potential for dissemination that these messages have, when transposed to other contexts, such as collective mobilizations or social networks. The double character of registration in the public space is also noteworthy: they are a memory of past claims and an incentive for future struggles. Being apparently silent, these counter-visualities produce noise, changing the urban landscape and driving social and political transformations.Keywords: photography, protest, gentrification
