Background The COVID-19 pandemic threatens access to sexual and reproductive health and rights. With global health emergencies, there is often a total reversal of priorities and sexual and reproductive health rights services may become challenging. The aim of this study was to establish the challenges to sexual and reproductive health and rights among Ugandan youth during the lockdown due to COVID-19 pandemic. Methods This was an online cross-sectional study carried out from April 2020 to May 2020 in Uganda. An online questionnaire was used and participants aged 18 to 30 years recruited using the snowballing approach. The statistical analysis was done using STATA version 14.Results Out of 724 participants, 203 (28%) reported not having information and/or education concerning sexual and reproductive health (SRH). About a quarter of the participants (26.5%) reported not having testing and treatment services of Sexual transmitted Infections available during the lockdown. Lack of transport means was the commonest (68.7%) limiting factor to access to SRH services during the lockdown followed by the long distance from home to health facility where to get the services (55.2%), cost of services (42.2%) and curfew (39.1%). Sexually transmitted diseases were the commonest (40.4%) challenge relating to SRH during this lockdown followed by unwanted pregnancy (32.4%) and sexual abuses (32.4%). The Multivariate Regression Analysis shows that challenges were more prevalent among the co-habiting youth [APR: 2.3 (1.6 - 3.29), p<0.001] followed by unemployed (Volunteer or unpaid) [APR: 1.6 (1.03 - 2.64), p: 0.037] than others participants. Conclusions The findings of this study show that Ugandan youths have challenges to access to SRHR information and services during lockdown due to COVID-19. Cohabiting and unemployed participants were mostly affected among Ugandan youths. Lack of transport means and cost of services were the limiting factors to access SRHR services among youths. Therefore, effective measures should be put in place to ensure access and availability of SRHR for Ugandan youths during the COVID-19 lockdown.

Background Global health education partnerships should be collaborative and reciprocal to ensure mutual benefit. Utilisation of digital technologies can overcome geographic boundaries and facilitate collaborative global health learning. Global Health Classroom (GHCR) is a collaborative global health learning model involving medical students from different countries learning about each other’s health systems, cultures, and determinants of health via videoconference. Principles of reciprocity and inter-institutional partnership informed the development of GHCR. This study explores learning outcomes and experiences in GHCR between students from New Zealand and Samoa. Methods The study used a mixed methods approach employing post-GHCR questionnaires and semi-structured face-to-face interviews to explore self-reported learning and experiences among medical students in GHCR. The GHCR collaboration studied was between the medical schools at the University of Otago, New Zealand and the National University of Samoa, Samoa.ResultsQuestionnaire response rate was 85% (74/87). Nineteen interviews were conducted among New Zealand and Samoan students. Students reported acquiring the intended learning outcomes relating to patient care, health systems, culture, and determinants of health with regards to their partner country. There was evidence of attitudinal changes including cultural curiosity and humility. Some reported a vision for progress regarding their own health system. Students reported that interacting with their international peers in the virtual classroom made learning about global health real and tangible. Mutual benefit to students from both countries indicated reciprocity.Conclusions The study demonstrates GHCR to be a promising model for collaborative and reciprocal global health learning using a student-led format and employing digital technology to create a virtual classroom. The self-reported learning outcomes align favourably with those recommended in the literature. In view of our positive findings, we present GHCR as an adaptable model for equitable, collaborative global health learning between students in internationally partnered institutions.

Published: July 2020

Background: Low levels of serum magnesium (Mg) perturb renal tubular cell function and, lymphocyte resulting in renal deterioration and an imbalance in mononuclear cells. Here, we investigated the influence of hypomagnesaemia in patients with connective tissue disease (CTD). Methods: We retrospectively evaluated CTD patients who visited our hospital during 2019 with available serum Mg levels. Patients were divided into two groups, those with or without hypomagnesemia (<1.8 mg/dL) and compared by rate of hospitalization for severe infection and cumulative renal deterioration. They were also compared by fractions of lymphocytes, and natural killer (NK) and dendritic cell (DC) subsets as measured by fluorescence-activated cell sorting (FACS) analysis.Results: Among 284 patients, hypomagnesemia was detected in 63 (22.2%). Multivariate analysis revealed that use of proton-pump inhibitors (PPIs) (OR 1.48, p=0.01) and tacrolimus (TAC) (OR 6.14, p<0.01) was independently associated with hypomagnesaemia. Renal deterioration rate was significantly higher in TAC and/or PPI users with hypomagnesemia (p=0.01). Hospitalization rate for severe infection was also higher in patients with hypomagnesaemia (p=0.04). FACS analysis showed lower counts for CD8+ T cells, CD19+ B cells, NK cells, and DC in hypomagnesaemia (p=0.03, p=0.02, p=0.02, and p=0.03, respectively). Conclusions: Use of TAC and PPIs may be associated with hypomagnesaemia and lead to poor renal outcomes and severe infection in CTD.

Background: The development of thrombotic coagulopathy is frequent in COVID-19 patients, but the timing after infection, cerebral venous system involvement, treatment and outcome are uncertain.Case Presentation: We report a case of massive cerebral venous thrombosis occurring in the late phase of COVID-19 infection. Mild respiratory symptoms, without fever, started three weeks before headache and acute neurological deficits. She had no dyspnea, although she was hypoxic and with typical COVID-19 associated interstitial pneumonia. Brain CT scan showed a left parietal hypodense lesion with associated sulcal subarachnoid haemorrhage. CT angiography showed a massive cerebral vein thrombosis. An asymptomatic concomitant right internal iliac vein thrombosis was found. Both cerebral venous thrombosis and deep venous thrombosis were effectively treated with unfractionated heparin started on the day of admission, then shifted to low molecular weight heparin, with a favorable clinical course. Nasopharyngel swab, repeated twice, tested negative for SARS-CoV-2. Serological tests confirmed SARS-CoV-2 infection. Conclusions: Our case supports active surveillance and prevention of thrombotic complications associated with COVID-19, which may affect both peripheral and cerebral venous system. Early initiation of unfractionated heparin may lead to good neurological outcome.

Published: July 2020

We present a set of equations expressing the parameters of the magnetic interactions of an electronic system. This allows to establish a mapping between the initial electronic system and a spin model including up to quadratic interactions between the effective spins, with a general interaction (exchange) tensor that accounts for anisotropic exchange, Dzyaloshinskii–Moriya interaction and other symmetric terms such as dipole–dipole interaction. We present the formulas in a format that can be used for computations via Dynamical Mean Field Theory algorithms.
Finansowanie mezzanine jako interesująca alternatywa pozyskiwania kapitału
Authors: Włodarczyk Adam
Published: July 2020

Finansowanie mezzanine należy do niekonwencjonalnych metod finansowania. Wykorzystuje instrumenty hybrydowe i może przybierać różnorakie formy. W jego ramach występuje zarówno element dłużny, jak i kapitałowy. Charakterystyczne dla niego jest podporządkowanie wierzytelnościom głównym, dzięki czemu podmiot finansowany nie pogarsza swojej zdolności do zaciągania innych długów. Ta okoliczność wiąże się jednak z większym ryzykiem ponoszonym przez inwestora, który w zamian za to, dzięki tzw. equity kicker, będzie oczekiwał naturalnie wyższej stopy zwrotu niż przy tradycyjnych metodach finansowania. Adresatami finansowania mezzanine są podmioty rozwijające się bądź w trudnej sytuacji finansowej, które posiadają potencjał do wypracowywania zysków w przyszłości. Mezzanie zalicza się do rodzaju private equity. Rozwiązanie to przewiduje wiele korzyści dla partycypujących stron, w tym także podatkowe, wynikające ze strategii rule shopping. Może znaleźć zastosowanie w wielu branżach, m.in. w bankowości. Główną motywacją do skorzystania z niego może być chęć obniżenia kuponu odsetkowego towarzyszącego innym metodom finansowania.

Fighting Diabetes Mellitus: Pharmacological and Non-pharmacological Approaches
Authors: Wang Xin , Kang Jinhong , Liu Qing , Tong Tao , Quan Helong
Published: July 2020

Background:

The increasing worldwide prevalence of diabetes mellitus confers heavy public health
issues and points to a large medical need for effective and novel anti-diabetic approaches with negligible adverse
effects. Developing effective and novel anti-diabetic approaches to curb diabetes is one of the most foremost
scientific challenges.

Objectives:

This article aims to provide an overview of current pharmacological and non-pharmacological approaches
available for the management of diabetes mellitus.

Methods:

Research articles that focused on pharmacological and non-pharmacological interventions for diabetes
were collected from various search engines such as Science Direct and Scopus, using keywords like diabetes,
glucagon-like peptide-1, glucose homeostasis, etc.

Results:

We review in detail several key pathways and pharmacological targets (e.g., the G protein-coupled receptors-
cyclic adenosine monophosphate, 5′-adenosine monophosphate-activated protein kinase, sodium-glucose
cotransporters 2, and peroxisome proliferator activated-receptor gamma signaling pathways) that are vital in the
regulation of glucose homeostasis. The currently approved diabetes medications, the pharmacological potentials
of naturally occurring compounds as promising interventions for diabetes, and the non-pharmacological methods
designed to mitigate diabetes are summarized and discussed.

Conclusion:

Pharmacological-based approaches such as insulin, metformin, sodium-glucose cotransporters 2
inhibitor, sulfonylureas, glucagon-like peptide-1 receptor agonists, and dipeptidyl peptidase IV inhibitors represent
the most important strategies in diabetes management. These approved diabetes medications work via targeting
the central signaling pathways related to the etiology of diabetes. Non-pharmacological approaches, including
dietary modification, increased physical activity, and microbiota-based therapy are the other cornerstones for
diabetes treatment. Pharmacological-based approaches may be incorporated when lifestyle modification alone is
insufficient to achieve positive outcomes.

Curcumin is a major curcuminoid present in turmeric. The compound is attributed to various therapeutic
properties, which include anti-oxidant, anti-inflammatory, anti-bacterial, anti-malarial, and neuroprotection.
Due to its therapeutic potential, curcumin has been employed for centuries in treating different ailments. Curcumin
has been investigated lately as a novel therapeutic agent in the treatment of cancer. However, the mechanisms
by which curcumin exerts its cytotoxic effects on malignant cells are still not fully understood. One of the
main limiting factors in the clinical use of curcumin is its poor bioavailability and rapid elimination. Advancements
in drug delivery systems such as nanoparticle-based vesicular drug delivery platforms have improved several
parameters, namely, drug bioavailability, solubility, stability, and controlled release properties. The use of
curcumin-encapsulated niosomes to improve the physical and pharmacokinetic properties of curcumin is one such
approach. This review provides an up-to-date summary of nanoparticle-based vesicular drug carriers and their
therapeutic applications. Specifically, we focus on niosomes as novel drug delivery formulations and their potential
in improving the delivery of challenging small molecules, including curcumin. Overall, the applications of
such carriers will provide a new direction for novel pharmaceutical drug delivery, as well as for biotechnology,
nutraceutical, and functional food industries.
Arctium Lappa and Management of Liver Functions to Detoxify the Bloodstream
Authors: Mahboubi Mohaddese
Published: July 2020

Arctium lappa or burdock (Compositae family) is a perennial plant, native to Europe,
Northern Asia, and North America. Burdock roots are known as detoxifying herb to clear toxins
from the bloodstream. It seems that its effects are on the liver functions as it is main part of the
body for detoxifying the bloodstream. The aim of this review article was to evaluate the potency of
burdock in the management of liver functions in detoxifying the bloodstream. The information was
extracted from electronic resources (Google scholar, Science Direct, Springer, Magiran). The results
of the investigation exhibited that the studies are limited to animals, but the results of investigations
showed that burdock roots detoxify the liver against ethanol, carbon tetrachloride (CCL4),
acetaminophen, cadmium, and zinc oxide by improving the functions of liver enzymes. The anti-
oxidant, anti-inflammatory, and prebiotic effects of burdock roots may be involved in its effects
on liver enzymes and detoxifying the blood. Large clinical studies are required to confirm its efficacy
on liver functions and detoxifying the liver.

By transmission electron microscopy are studied two buffer structures based on AlGaN alloys doped with silicon and don't. The structures were grown on (111) orientated Si substrates by metal-organic vapour-phase epitaxy with consistently decreasing Al content. It is found that noticeable threading dislocation density reduction took place in intermediate layers at changing Al concentration from 32 to 23%. A phase decay and a composition modulation in growth direction in AlGaN layers with Al content 32, 23, 12 and 4% are observed. A model of the layers structure in the composition modulation area is proposed.
Client Satisfaction and Experience With Telepsychiatry: Development and Validation of a Survey Using Clinical Quality Domains
Authors: Serhal Eva , Kirvan Anne , Sanches Marcos , Crawford Allison
Published: July 2020

Background

Telepsychiatry is an increasingly used model of mental health care that connects patients with psychiatrists at a distance via videoconference. Telepsychiatry is an effective clinical intervention that improves access to quality care in regions with limited resources or in clinical situations where in-person care is unavailable.

Objective

This study aims to develop a validated survey tool to measure patient experience and satisfaction with telepsychiatry based on the quality of care domains. This study also seeks to understand which health service outcomes were most strongly correlated with overall satisfaction in the context of telepsychiatry.

Methods

The survey created in this study was developed and validated with a panel of subject matter and process experts and was piloted with 274 patients who received clinical consultations through the TeleMental Health Program at the Centre for Addiction and Mental Health. Factor analysis was used to determine correlations between questions and quality of care domains and was also used to assess model fit.

Results

The study provides a validated survey to measure patient satisfaction and experience with telepsychiatry across 4 domains: access and timeliness, appropriateness, effectiveness, and safety. Both safety and access and timeliness were found to be statistically significant predictors of satisfaction in our sample.

Conclusions

By situating patient satisfaction and experience within this framework, the survey facilitates patient data collection and interpretation through a clinical quality lens.
Patterns of Use and Key Predictors for the Use of Wearable Health Care Devices by US Adults: Insights from a National Survey
Authors: Chandrasekaran Ranganathan , Katthula Vipanchi , Moustakas Evangelos
Published: July 2020

Background

Despite the growing popularity of wearable health care devices (from fitness trackes such as Fitbit to smartwatches such as Apple Watch and more sophisticated devices that can collect information on metrics such as blood pressure, glucose levels, and oxygen levels), we have a limited understanding about the actual use and key factors affecting the use of these devices by US adults.

Objective

The main objective of this study was to examine the use of wearable health care devices and the key predictors of wearable use by US adults.

Methods

Using a national survey of 4551 respondents, we examined the usage patterns of wearable health care devices (use of wearables, frequency of their use, and willingness to share health data from a wearable with a provider) and a set of predictors that pertain to personal demographics (age, gender, race, education, marital status, and household income), individual health (general health, presence of chronic conditions, weight perceptions, frequency of provider visits, and attitude towards exercise), and technology self-efficacy using logistic regression analysis.

Results

About 30% (1266/4551) of US adults use wearable health care devices. Among the users, nearly half (47.33%) use the devices every day, with a majority (82.38% weighted) willing to share the health data from wearables with their care providers. Women (16.25%), White individuals (19.74%), adults aged 18-50 years (19.52%), those with some level of college education or college graduates (25.60%), and those with annual household incomes greater than US $75,000 (17.66%) were most likely to report using wearable health care devices. We found that the use of wearables declines with age: Adults aged >50 years were less likely to use wearables compared to those aged 18-34 years (odds ratios [OR] 0.46-0.57). Women (OR 1.26, 95% CI 0.96-1.65), White individuals (OR 1.65, 95% CI 0.97-2.79), college graduates (OR 1.05, 95% CI 0.31-3.51), and those with annual household incomes greater than US $75,000 (OR 2.6, 95% CI 1.39-4.86) were more likely to use wearables. US adults who reported feeling healthier (OR 1.17, 95% CI 0.98-1.39), were overweight (OR 1.16, 95% CI 1.06-1.27), enjoyed exercise (OR 1.23, 95% CI 1.06-1.43), and reported higher levels of technology self-efficacy (OR 1.33, 95% CI 1.21-1.46) were more likely to adopt and use wearables for tracking or monitoring their health.

Conclusions

The potential of wearable health care devices is under-realized, with less than one-third of US adults actively using these devices. With only younger, healthier, wealthier, more educated, technoliterate adults using wearables, other groups have been left behind. More concentrated efforts by clinicians, device makers, and health care policy makers are needed to bridge this divide and improve the use of wearable devices among larger sections of American society.

Published: July 2020

BACKGROUND

Essential workers have been shown to present a higher prevalence of positive screenings for anxiety and depression during the COVID-19 pandemic. Individuals from countries with socioeconomic inequalities may be at increased risk for mental health disorders.

OBJECTIVE

We aimed to assess the prevalence and predictors of depression, anxiety, and their comorbidity among essential workers in Brazil and Spain during the COVID-19 pandemic.

METHODS

A web survey was conducted between April and May 2020 in both countries. The main outcome was a positive screening for depression only, anxiety only, or both. Lifestyle was measured using a lifestyle multidimensional scale adapted for the COVID-19 pandemic (Short Multidimensional Inventory Lifestyle Evaluation–Confinement). A multinomial logistic regression model was performed to evaluate the factors associated with depression, anxiety, and the presence of both conditions.

RESULTS

From the 22,786 individuals included in the web survey, 3745 self-reported to be essential workers. Overall, 8.3% (n=311), 11.6% (n=434), and 27.4% (n=1027) presented positive screenings for depression, anxiety, and both, respectively. After adjusting for confounding factors, the multinomial model showed that an unhealthy lifestyle increased the likelihood of depression (adjusted odds ratio [AOR] 4.00, 95% CI 2.72-5.87), anxiety (AOR 2.39, 95% CI 1.80-3.20), and both anxiety and depression (AOR 8.30, 95% CI 5.90-11.7). Living in Brazil was associated with increased odds of depression (AOR 2.89, 95% CI 2.07-4.06), anxiety (AOR 2.81, 95%CI 2.11-3.74), and both conditions (AOR 5.99, 95% CI 4.53-7.91).

CONCLUSIONS

Interventions addressing lifestyle may be useful in dealing with symptoms of common mental disorders during the strain imposed among essential workers by the COVID-19 pandemic. Essential workers who live in middle-income countries with higher rates of inequality may face additional challenges. Ensuring equitable treatment and support may be an important challenge ahead, considering the possible syndemic effect of the social determinants of health.

Published: July 2020

Investigations of the angled ballistic impact behavior on Carbon Kevlar® Hybrid fabrics with assorted volumes of carbon nanotubes (CNTs) into epoxy are presented. The ballistic impact behavior of the epoxy composites with/without CNTs is compared. Individual impact studies are conducted on the composite plate made-up of Carbon Kevlar Hybrid fabrics with diverse volumes of CNTs. The plate was fabricated with eight layers of equal thickness arranged in different percentages of CNTs. A conical steel projectile is considered for a high velocity impact. The projectile is placed very close to the plate, at the centre and impacted with sundry speeds. The variation of the kinetic energy, the increase in the internal energy of the laminate and the decrease in the velocity of the projectile with disparate angles are also studied. Based on the results, the percentage of CNTs for the ballistic impact of each angle is suggested.  The solution is based on the target material properties at high ballistic impact resistance, the inclined impact and the CNT volumes. Using the ballistic limit velocity, contact duration at ballistic limit, surface thickness of target and the size of the damaged zone are predicted for fabric composites.

Published: July 2020

Mammary adenocarcinomas with metastases are more common in dogs than in cats. Their incidence is 1 in every 4,000 cats. In routine veterinary practice, laboratory exams for diagnosis of these neoplasms are nonspecific and scarcely used. Even though invasive procedure, biopsy, and histopathological findings are the gold standards that define the clinical approach, the clinical evaluation, and image assessment lead the way to the proper treatment, especially when surgical intervention is a possibility. This study describes the clinical signs, histopathological aspects, radiological and scintigraphic findings of a cat with mammary adenocarcinoma and metastases evaluated one hour after intravenous administration of 99mTc-thymine. Our focus was not to discuss the pathological aspects of the disease but the Nuclear Medicine role in metastases detection. Metastases, when lesser than 4mm, could go unnoticed by radiological exams, whereas scintigraphy may detect them. Using 99mTc-thymine scintigraphy, we successfully detected unsuspected metastases in the lungs, liver, and right kidney. Early diagnosis is the key to a better rate of survival due to the given treatment and prognostic. Hence, we strongly recommend the use of 99mTc-thymine scintigraphy as a complementary tool for breast cancer diagnosis in veterinary care.

Sociology as a science has a variety of paradigms born of social scientists. Some of these are the sociology paradigm according to George Ritzer (which consists of a social facts paradigm, a social definition paradigm, a social behavior paradigm), and a sociology paradigm according to Margaret M. Poloma (consisting of a naturalistic / positivistic paradigm, a humanistic / interpretative paradigm, and a paradigm evaluative). This article aims to integrate between the sociology paradigm according to Ritzer and the sociology paradigm according to Poloma through comparative analysis that refers to paradigm elements consisting of ontological, epistemological, methodological, and axiological dimensions

BODY PAINTING: CORPOS CENOGRÁFICOS
Authors: Magalhães Mona Ferreira
Published: July 2020

Este ensaio foi apresentado na 14ª Prague Quadrennial of Performance Design and Space – PQ2019, no PQ talks - mesa Expanding Scenography . Trata-se da body painting como linguagem artística com potencial para produzir interferência urbana, na qual os corpos podem se camuflar, fundindo-se com o ambiente em que vivem, ou destacando-se do espaço da cidade e do ambiente social, provocando efeitos extracotidianos em ações puramente performativas . Assim, temos um plano de expressão que se articula com um plano de conteúdo, materializado em enunciados pintados no corpo de um sujeito historicamente localizado em um espaço e tempo definidos, compondo, portanto, conforme Patrice Pavis (1999, p. 232), um "cenário de ambulante", capaz de ser um "elemento estético totalizante da encenação". A pintura corporal é dotada de um plano de expressão visual, no qual cores, formas, topologia e matéria se fundem, no suporte corporal, para criar códigos socialmente interpretáveis pelo hábito ou para produzir sentidos inesperados. Existe uma correspondência entre conteúdos que oscilam em relação ao plano de expressão, produzindo desde os sentidos usuais até os surpreendentes. Como um "cenário ambulante", o corpo sob a pintura pode ser recuado ou visível, deformado ou invertido, em um espaço e tempo operados na dimensão do ato discursivo, isto é, aqui e agora. Assim, declarações pintadas podem definir o corpo como um contraponto e / ou uma reiteração em relação à cidade (Espaço / aqui). A sensação ou ilusão de ótica de um corpo ausente nas pinturas corporais libera, portanto, esse corpo dos sentidos sociais enraizados culturalmente sob a pele, deixando-o livre para provocar novos sentidos e criar outros espaços. Palavras-chavesBody painting.

A MOSTRA DAS ESCOLAS NA QUADRIENAL DE PRAGA-TERRITÓRIO FÉRTIL
Authors: Viana Fausto Roberto Poço
Published: July 2020

O objetivo principal deste artigo é mostrar como alunos e professores podem ter uma atividade pedagógica sem igual ao participar da preparação para a Mostra das Escolas de Cenografia que acontece na República Tcheca de quatro em quatro anos, a Quadrienal de Praga. Ao privilegiar o processo didático e não a disputa para a seleção para a exposição no stand em Praga, no processo curatorial de 2011 é possível perceber que o processual, o desenvolvimento e a preparação podem ser tão ou mais significativos que o resultado a ser visto pelo público. O artigo apresenta ainda dados estatísticos sobre os alunos que participaram daquela edição e de como está a carreira de cada um deles hoje. Palavras-chavesMostra dos Estudantes. Cenografia.

O FIGURINO COMO INSTRUMENTO POLÍTICO: A IMPORTÂNCIA DA ARTE QUESTIONADORA
Authors: Xavier Mariana Carvalho , Muniz Rosane
Published: July 2020

Os movimentos políticos, econômicos e sociais que ocorrem em cada país e ao redor do mundo podem ser temas e/ou influências na concepção da linguagem de uma obra artística. Este artigo objetiva compreender um dos elementos da cena, o figurino, enquanto um instrumento político, um manifesto, investigando se é possível manifestar estas influências criadoras também em uma autoria dos trajes elaborados para uma performance, de forma a compor a dramaturgia. Três trajes de cena, em três contextos políticos diferentes, são analisados neste estudo: da violência política mexicana à polarização do Brasil durante as eleições de 2018, passando pela crise dos refugiados que marcou e marca a história mundial. Palavras-chavesFigurino. Política. Performance. Cultura. Revolução.

METÁFORAS DO PENSAMENTO EM CENA: A ESPETACULARIDADE COTIDIANA DE UM TERRITÓRIO EXTRAORDINÁRIO OCUPADO POR PESSOAS EM RESTRIÇÃO DE LIBERDADE
Authors: Veloso Jorge , Porto João Timótheo Maciel
Published: July 2020

Trata-se este trabalho de uma reflexão sobre as relações estabelecidas nos espaços de restrição de liberdade, a partir de observações no sistema prisional do Distrito Federal. Ali, homens e mulheres transformam suas regras, contrarregras, interditos e metáforas, criadas para, a partir de seu estar juntos, em estetizações produzidas para, de alguma maneira, territorializar seus lugares de convivência. Sustentando-se nos pressupostos da Etnocenologia para as noções de espetacularidade e teatralidade, este estudo privilegia os diálogos com os estudos da linguagem, nas analogias das Metáforas da vida Cotidiana, propostos por George Lakoff e Mark Johnson e com as formulações de territorialidades e não-lugares, de Marc Augé. Parte de anotações sobre comportamentos corporais e linguísticos de pessoas em conflito com a Lei, observados, prioritariamente em penitenciárias, onde um dos autores, como membro do corpo sócio-educativo, é professor de Artes Cênicas. Palavras-chavesEtnocenologia.

Da avaliação em larga escala ao furor avaliativo
Authors: Passone Eric Ferdinando Kanai
Published: July 2020

Este artigo aporta uma reflexão acerca dos efeitos das políticas educacionais de avaliação da educação básica associadas às políticas de responsabilização escolar, enquanto dispositivo da nova gestão pública. A partir do aporte teórico dos estudos de politicas públicas de educação e de fundamentos do campo de pesquisa em psicanálise e educação, apresentam-se os resultados de uma investigação de pós-doutoramento, de cunho qualitativo e exploratório, que investigou as práticas discursivas em relação ao uso dos resultados das avaliações externas como meio de gestão e responsabilização escolar. Por meio de pesquisa bibliográfica e pesquisa de campo foram entrevistados dez profissionais, entre diretores, coordenadores pedagógicos e professores, da rede estadual de São Paulo. A análise de tais discursos revela o furor avaliativo como uma saída perversa à educação escolar, o qual conduz à paixão instrumental e tende à degradação do ato educativo.
Sobre as Bases Videográficas (ou Cinematográficas) da Língua Brasileira de Sinais
Authors: Santos Marcelo
Published: July 2020

Este artigo sugere que a noção de cinematografia, concebida por Sergei Eisenstein como “montagem”, a combinação de cenas que são representativas, de significado único e neutras em conteúdo, em contextos e séries intelectuais, através das quais se consegue produzir um “cinema intelectual”, talvez seja base para pensar não apenas o cinema em seus próprios termos, mas também as línguas de sinais, cujo princípio semiótico, eis a hipótese de trabalho, é o mesmo do cinema eisensteiniano. Inicialmente, examina-se a noção de ideograma, signos figurativos não fonéticos criados para representar existentes ou ideias. Na sequência, fala-se do ideograma como base do cinema de Eisenstein e de como este mesmo alicerce parece importante para se refletir sobre a Língua Brasileira de Sinais, inclusive sobre o seu registro.
Conceitos junguianos aplicados à análise fílmica
Authors: Lunardelli Fatimarlei , Pimenta Maria Alzira de Almeida
Published: July 2020

O cinema é um produto da criação humana que desafia a ser decifrado. Vários são os instrumentos usados na tarefa de análise das relações que um filme suscita com outros universos de vivência do ser humano. Este artigo apresenta a análise do filme A História sem Fim (The Neverending Story) - uma produção alemã de 1984, dirigido por Wolfgang Petersen, a partir de conceitos da Teoria Junguiana. Como resultado, o processo de individuação, essencial e complexo para qualquer pessoa, vai sendo desvelado na análise dos mitos, dos símbolos e dos personagens que perpassam as cenas poéticas dessa obra de arte atemporal.
