Published: July 2020

Abstract. Analysis of short sediment cores collected in Grand Lake, Labrador, revealed that this lake is an excellent candidate for the preservation of laminated sediments record. The great depth of Grand Lake, the availability of fine sediments along its tributaries, and its important seasonal river inflow have favored the formation of a 160 years-long clastic varved sequence. Each varve represents one hydrological year. Varve formation is mainly related to spring discharge conditions with minor contributions from summer and autumn rainfall events. The statistically significant relation between varve parameters and the Naskaupi river discharge observations provided the opportunity to develop local hydrological reconstructions beyond the instrumental period. Mean detrital layer thickness and the grain-size (99th percentile) series extracted from each varve yields the strongest correlations with instrumental data (r = 0.69 and 0.76) and have been used to reconstruct Naskaupi River mean and maximum annual discharges, respectively, over the 1856–2016 period. The reconstructed Q-mean series suggest that high Q-mean years occurred during the 1925–1960 period and a slight decrease in Q-mean take place during the second half of the 20th century. Independent reconstructions based on rainfall-runoff modeling of the watershed from historical reanalysis of global geopotential height fields display a significant correlation with the reconstructed Naskaupi River discharge based on varve physical parameters. The Grand Lake varved sequence contains a regional hydroclimatic signal as suggested by the statistically significant relation between mean detrital layer thickness series and the observed Labrador region Q-mean series extracted from five watersheds of different size and location.
A two-stage Bayesian multi-model framework for improving
multidimensional drought risk projections over China
Authors: Zhang Boen , Wang Shuo , Zhu Jinxin
Published: July 2020

Abstract. Understanding future drought risk is a prerequisite for developing climate change adaptation strategies and for enhancing disaster resilience. In this study, we develop multi-model probabilistic projections of multidimensional drought risks under two representative emission scenarios (RCP4.5 and RCP8.5) through a copula-based Bayesian framework. An ensemble of five regional climate simulations, including four from the CORDEX East Asia experiment and one from the Providing REgional Climate Impacts for Studies (PRECIS) simulation, is used to project future changes in hydroclimatic regimes over China. A new Bayesian copula approach is introduced to uncover underlying interactions of drought characteristics and associated uncertainties over 10 climate divisions of China. The proposed Bayesian framework explicitly addresses the cascade of uncertainty in high-resolution projections of multidimensional drought risks. Our findings reveal that precipitation and potential evapotranspiration (PET) are projected to increase for most areas of China, while increasing radiative forcing is expected to amplify the increase in PET but does not cause significant changes in the precipitation projection. In addition, the drought duration and severity are projected to substantially increase for most areas of China. The estimated drought risks in China are expected to become more than double under both emission scenarios. The extreme droughts are projected to intensify in terms of frequency and associated risks as the radiative forcing increases.
Manifest Heritages of Family and Nation: Embodying “All the Ancestors” in Guyanese Komfa
Authors: Peretz Jeremy Jacob
Published: July 2020

This article offers comparative ethnographic exploration of Komfa ritual engaged to “entertain the ancestors” that is central to the way of life of Spiritualists in Guyana. Practiced primarily by Guyanese of African descent and considered an Africa-derived tradition, Komfa worldview nonetheless draws on cultural inheritances of various Guyanese backgrounds. Embracing Komfa worlds serves as historical and genealogical inquiry into often indistinct, polysemous pasts wherein spirit guides lead devotees through emancipatory journeys of familial and personal (re)discovery. Komfa can best be understood through comparative analyses foregrounding “adjacent” Black Atlantic religious idioms. Frameworks developed in interrogating practices at the “margins” of Candomblé, Lukumí, and Vodou situate Komfa and the spectrum that African-inspired religions encompass. In particular, existing ethnographic literature on Espiritismo as practiced in Cuba and elsewhere furnishes critical perspectives through which to understand Komfa that are more adequate than the bodies of scholarship consulted by researchers studying Komfa thus far.
The Art of Sweeping Sickness and Catching Death: Babalú Aye, Materiality, and Mortality in Lukumí Religious Practice
Authors: Tsang Martin
Published: July 2020

This article explores the ritual act of sweeping away sickness from the body as associated with Babalú Aye, the deity of healing and miracles. Babalú Aye is worshipped by adherents of Yorùbá and Dahomean groups and their descendants worldwide, and this article focuses on the curative arts and articulations of this orisha/fodun in Cuba's Afro-Atlantic religious complex. Babalú Aye's materiality and rites encompass unique vernaculars of space, performativity, and materiality within Lukumí religion; I show how the deity crosses borders and boundaries unlike any other in the pantheon. Through an examination and focus on Babalú Aye's broom, and associated ritual and medicinal technologies his priests and devotees employ in his healing rites, I posit that Babalú Aye's aesthetics and ceremonies reorder and equilibrate the body, removing death and sickness. Sweeping and carefully choreographed actions that are designed to detach, catch, and remove Ikú/death and Arun/sickness are the means by which his priests restore health, acts that comprise a Lukumí response to the need for a spiritually aligned system of healthcare. By extension, the modalities of divination, initiation, offerings, sacrifice, herbalism, music, dance, and prayer are composite strategies that form part of Babalú Aye's healing repertoire—they are the foundational elements of practice that are ultimately employed to restore health and to promote and prolong life in Lukumí worship.

Published: July 2020

Background: The work environment of nurses is characterized by physical and mental hazards liable to cause exhaustion and lead them to take psychoactive substances as coping strategy. Objective: To investigate nurses’ perception of the work environment influence on psychoactive substance intake. Methods: Exploratory, descriptive and qualitative study with 14 nurses in two public hospitals. Data were collected through semi-structured interviews and subjected to content analysis. Results: Staff and material shortages, submission, lack of autonomy, conflict in interpersonal relationships and power struggles were the main reasons for nurses to take psychoactive substances. Conclusion: Nurses are exposed to stressors in the workplace, including understaffing, power struggles, interpersonal conflict and lack of autonomy, which may lead them to take legal or illegal drugs.

Authors: Silva Luvanor Santana , Lima Isael João , Filho Edil Albuquerque , Santos Ravi Marinho , Porto Solange Magalhães , Oliveira Saulo Fernandes
Published: July 2020

Background: Health care workers are exposed to a high workload, resulting in an increase of job tasks and reduced physical activity, with consequent impairment of their quality of life. Physical activity is essential to improve motor skills and performance at work, and contributes to a healthy lifestyle. Objective: To analyze the relationship between quality of life and physical activity among Family Health Support Unit (FHSU) workers. Methods: We analyzed 19 FHSU workers aged 31.05±6.63 years old at the three FHSUs in Vitória de Santo Antão, Pernambuco, Brazil. For data collection we administered WHOQOL-BREF and Baecke’s questionnaire. Normality was investigated by means of the Shapiro-Wilk test and data were subjected to the Pearson correlation. Results: We found positive correlation between the global score on physical activity and the scores on exercise and active leisure (r=0.852, p<0.001) and work/school activity (r=0.611, p<0.001) domains and between quality of life physical health domain and the global score on usual physical activity (r=0.520, p<0.05). We further found significant correlation between years in the job and the physical activity exercise and active leisure domain (r=-0.649, p<0.001) and physical activity at work (r=-0.559, p<0.05). Conclusion: The results evidence significant correlation between physical activity and quality of life. Physical activity is essential to ensure continuity in job tasks, in addition to beneficial effects on social aspects.
Presenteeism among health care workers: literature review
Authors: Homrich Paulo Henrique Poti , Dantas-Filho Fabio Fernandes , Martins Laura Luna , Marcon Emilian Rejane
Published: July 2020

Presenteeism is an occupational and psychosocial phenomenon with negative impact on the work environment. In addition to causing losses in productivity losses, it also has implications for the state of health of workers. Therefore, presenteeism is likely to become a serious public health problem. The aim of the present study was to discuss the implications, means for evaluation and impact of presenteeism on the health and work of health care workers. We performed a literature search in database PubMed using keywords presenteeism, absenteeism, nurse presenteeism, physician presenteeism, sickness presenteeism, physician health organization, and working sick. We conclude that adequate assessment, raising the health managers’ awareness about the risks and harms associated with this phenomenon, and developing management tools will contribute to reduce the impact of presenteeism. This seems to be the proper path to make this problem more visible and hinder its growth.
Work-related disorders among employees of a federal public university in southern Brazil
Authors: Andersen Cristine Scattolin , Lobato Marcos Antônio de Oliveira Lobato
Published: July 2020

Background: Work-related disorders have considerable impact on the health of workers at a high cost for national budgets. Yet these conditions are globally underreported, less than 8% in Brazil. Shortcomings in health policies and records hinder attempts at establishing the health profile of civil servants in Brazil, who represent 8% of the local workforce. Objective: To establish the profile of federal civil servants with work-related disorders and relate it to diagnoses recorded in Civil Servant Work Accident Reports (CS/WAR) issued at a federal public university in southern Brazil. Methods: We analyzed 166 CS/WAR; 79.52% corresponded to women, average age 46.46 (SD=10.06), ≥21 years in the job (34.9%), workers at the university hospital (64.46%) and medium- or technical level health care workers (45.78%). Mean duration of sick leave spells was 11.89 (SD=21.33) days. About 41.57% of CS/ WAR did not provide an ICD-10 code; 82.5% of the rest corresponded to work accidents, mainly lower extremity injury (31.5%) and 17.50% to occupational diseases, most commonly low back injury and infectious diseases (17.7% each). Conclusion: The results reinforce the need to improve the record system in public service facilities to enable strategies targeting the main health problems exhibited by this population of workers.
Licenciamento voluntário de patentes e acesso a medicamentos: o caso do sofosbuvir
Authors: Chein Feres Marcos Vinício , Da Silva Sant'Anna Leonardo , Silva Alan Rossi
Published: July 2020

O presente artigo visa a investigar empiricamente se o licenciamento voluntário do sofosbuvir pode ser considerado uma estratégia adequada para a ampliação do acesso a este medicamento. Esta pesquisa foi construída com base em um estudo de caso único, holístico e descritivo sobre o tema, de acordo com asdefinições elaboradas por Robert Yin e com as proposições teóricas formuladas por Susan Sell. Como resultado principal, foi possível inferir que o licenciamento voluntário parece não ser uma estratégia capaz de ampliar efetivamente o acesso ao sofosbuvir, podendo servir até mesmo a objetivos contrários a este,como a limitação da concorrência e a maximização da exclusividade conferida pela patente da licenciante. Ademais, também foi possível concluir que, em qualquer caso, esta estratégia não pode ser considerada automaticamente adequada para a ampliação do acesso a medicamentos protegidos por patentes.

Da transnacionalidade financeira de Bretton Woods às moedas digitais
Authors: Piffer Carla , Cruz Paulo Márcio , Teixeira Alessandra Vanessa
Published: July 2020

Este artigo versa sobre a transnacionalidade financeira a partir do encontro de Breeton Woods e sua evolução até a criação das moedas digitais. Seu objetivo é demostrar que a transnacionalização da moeda evidencia o início de uma nova identidade monetária transnacional, para a qual os Estados, na condição deentes soberanos dotados de poder político e jurídico, não estão preparados. A fim de alcançar tal objetivo, o estudo analisa o surgimento da transnacionalização da economia e sua evolução. Na sequência, aborda-se acriação e o desenvolvimento as moedas, até aquelas criadas na era digital transnacionalizada, com devida ênfase às criptomoedas e aos bitcoins para, ao final, sopesar sobre a relativização da soberania estatal frente o novo paradigma monetário, de caráter transnacional, desterritorializado no universo virtual.
Movimento, teoria e institucionalização feminista na primeira onda de protagonismo político das mulheres

Este trabalho tem o objetivo de fazer uma genealogia histórica dos movimentos e das teorizações surgidos das demandas das mulheres, bem como das institucionalizações políticas daí decorrentes, originando o que hoje se costuma chamar de ‘Primeira Onda do Movimento Feminista’, tanto no Brasil quanto internacionalmente. O método utilizado é o fenomenológico, pois o que se pretende é uma aproximação ao fenômeno, de modo a poder demonstrar diretamente e não a partir de postulados de outros fenômenos ou de doutrinas tradicionais.
A recepção neoconservadora estadunidense da crítica de Leo Strauss ao projeto moderno weberiano de uma ciência livre de valores
Authors: Coelho de Azevedo Bussinguer Elda , Bisi Leonel Wilton
Published: July 2020

O propósito deste artigo é identificar a crítica de Leo Strauss à proposta de Max Weber de fundação de uma Ciência Social moderna axiologicamente neutra, além de tecer considerações sobre a influência dessa avaliação straussiana no pensamento neoconservador estadunidense. Pretende-se demonstrar que aconsequência mais profunda produzida pela Ciência Social Moderna - calcada na distinção entre fatos e valores enquanto critério fundamental para engendrar conhecimento social objetivo - é a descrença (ou até mesmo a própria recusa) dos princípios fundamentais que informam a civilização ocidental, a saber: arazão, a moral e a paz. A fim de atingir o objetivo central de pesquisa, este artigo apresenta a crítica straussiana ao projeto weberiano da Ciência Social antecedida por uma sintética contextualização do pensamento de Leo Strauss e sucedida por ponderações que indicam a influência de Strauss na constituição do pensamento neoconservador estadunidense.
HISTORIAS ORALES COMO HERRAMIENTA PARA LA CONVIVENCIALIDAD

Published: July 2020

Son numerosas las formas de investigación en las que se utilizan fuentes orales, algunas de las cuales se denominan epistemológicas, otras metodológicas y otras técnicas o herramientas. Presentamos un estudio comparativo entre once proyectos de investigación trabajados con y desde la gente, realizados a lo largo de 25 años, entre los cuales, en seis se ha trabajado con la herramienta historias orales y en cinco, no. Primeramente, hemos aclarado nuestra posición epistemológica y hemos contrastado la herramienta historias orales con las historias de vida y la historia oral. Como resultados principales de este contraste, destacamos la importancia de comprender todos estos dispositivos como herramientas, que no son inocuas. La herramienta historias orales sirve para la dinamización comunitaria solo si es adecuada para el contexto y el momento de la comunidad en la que se utiliza. Añadimos algunas reflexiones sobre las culturas populares y la dinamización comunitaria.
UMA PERSPECTIVA DE GÊNERO SOBRE A PARTICIPAÇÃO DAS MULHERES NOS PROCESSOS DE PAZ
Authors: Pereira Pacheco Maria Luiza
Published: July 2020

Por muito tempo, a paz, a violência e a segurança foram termos associados ao Estado. Na década de 1980, no entanto, os movimentos acadêmicos para a incorporação da mulher nos estudos de Relações Internacionais foram sendo desenvolvidos a partir das teorias pós-positivistas, incluindo as Teorias Feministas de R.I. Neste contexto, questionamentos sobre as marginalizações feminina, as violências, o militarismo e as relações de poder nos níveis pessoal e internacional passaram a incorporar uma nova abordagem de segurança vinculada ao gênero como categoria de análise. Assim, tendo como pressuposto a importância dos processos de paz para o desenraizamento das violências e a construção das pazes, este artigo propõe investigar os avanços e desafios da participação das mulheres nos processos de resolução de conflitos, no peacekeeping como militares, no peacemaking como negociadoras, mediadoras e signatárias, e no peacebuilding como civis. Nesta lógica exploratória, utiliza-se a Resolução 1325 sobre Mulheres, Paz e Segurança do Conselho de Segurança das Nações Unidas como o objeto de análise a fim de compreender a sua representação como instrumento político e suas consequências para as questões de gênero, no que permeia a prioridade e o esforço para a participação das mulheres na construção da paz e da segurança.
As exigências da política nacional de habitação e a sua operacionalidade na cidade de Cajazeiras (PB)
Authors: Moares Sharlene Dantas , Cruz Lindalva Alves , De Oliveira Andréia Braga
Published: July 2020

Este artigo é parte do trabalho de conclusão do curso de Serviço Social na Faculdade Santa Maria, Cajazeiras - PB no ano de 2017. Aqui, foi analisado a operacionalidade da Política Nacional de Habitação (PNH) no Conjunto Habitacional Recreio na cidade de Cajazeiras na Paraíba, e se a construção contemplou as exigências da produção de habitação de interesse social, sendo esse direcionado para a população de baixa renda. Enfatizou-se a implementação da Política Nacional de Habitação (2004) através do programa Minha Casa Minha Vida, priorizando o subsistema de interesse social. Os procedimentos metodológicos foram de caráter qualitativo, com pesquisa documental e de campo. Para coleta dos dados, adotou-se a observação em campo, e a entrevista. Os resultados revelaram que a operacionalidade da Política Nacional de Habitação (PNH) aconteceu de forma conflituosa, pois foram identificadas falhas no processo que envolveu o Conjunto Habitacional Recreio referente aos critérios de qualidade e conforto das famílias, bem como a não concessão da documentação definitiva, além de infraestrutura incompleta. Apesar disso, é inquestionável a importância dessa política para o acesso à moradia. Hoje, diferente dos últimos governos, enfrenta-se o verdadeiro desmonte da Política Nacional de habitação.

No presente artigo expõe-se, de forma aproximativa, os resultados de uma pesquisa realizada sobre o Serviço Social na Atenção Primária à Saúde, com ênfase para a atuação profissional nos Núcleos de Apoio à Saúde da Família (NASFs) no Distrito Federal. A arguição, de base qualitativa, objetivou conhecer as atribuições, competências e condições laborais de assistentes sociais neste espaço sócio- ocupacional, tendo como ponto de partida os processos de intensificação e precarização do exercício profissional, especialmente, em um contexto de ofensiva neoliberal, medidas de austeridade e ajuste fiscal, com adoção de políticas minimalistas, focalizadas e assistencialistas no trato das expressões da “questão social”.
Economia popular solidária e seu programa social
Authors: Goerck Caroline
Published: July 2020

Este artigo objetiva demonstrar os resultados de uma pesquisa que averiguou a contribuição do extinto Programa de Economia Solidária em Desenvolvimento para a viabilidade das experiências coletivas de geração de trabalho e renda no Rio Grande do Sul. Este programa social foi criado em 2003, pelo governo federal, com vistas a fortalecer os empreendimentos de geração de trabalho e renda, juntamente com a Secretaria de Economia Solidária – Senaes – que foi extinta em 2016. A operacionalização do mencionado Programa ocorreu por meio de parcerias estabelecidas entre o estado (Secretaria Nacional de Economia Solidária – Senaes), instituições da sociedade civil, outros setores governamentais e incubadoras universitárias. Partiu-se do pressuposto que o Programa se constituiu como elemento potencializador de geração de renda para os sujeitos que estavam à margem do mercado formal de trabalho, especialmente os menos qualificados, mas que, contraditoriamente, também se configurou em mecanismos de regulação do capitalismo, para atenuar os conflitos de classe e reproduzir o sistema. Constatou-se, que, tanto o estado, por meio do Programa, em parceria com instituições da sociedade civil, outros setores governamentais, incluindo as incubadoras universitárias podiam, mesmo que de forma incipiente, potencialmente viabilizar as experiências de Economia Popular Solidária.
Intervenções do Cejusc sobre a violência doméstica contra a mulher na Comarca de União da Vitória - PR
Authors: Milani Maria Luiza , Amarantes Lucimara Dayane
Published: July 2020

Objetiva-se, com o presente artigo, explicar a violência doméstica como problema de múltiplas dimensões, que atinge as vítimas silenciosamente e não obedece a nenhuma regra rígida (nível social, econômico e cultural): tem tendência de impedir ou dificultar o desenvolvimento físico e mental das vítimas e agressores. Representa carga econômica em termos de produtividade, aumento do uso de serviços sociais e interferência na dignidade humana. Incide no desenvolvimento de uma nação, estado e região. Na comarca de União da Vitória, observou-se que a violência é mais expressiva que os dados manifestados. O estudo foi produzido pela pesquisa bibliográfica e documental na instituição CEJUSC e o seu papel inovador no Poder Judiciário e nos setores de serviços que deveriam constituir a rede socioassistencial. Daí a importância da pesquisa que trouxe para discussão este tema e sustentou proposições, estratégias e intervenções mais definitivas, tanto para prevenção como para uma possível erradicação da violência doméstica.
Interest in STEM disciplines and teaching methodologies. Perception of secondary school students and preservice teachers
Authors: Hernández-Serrano María José , Muñoz-Rodríguez José Manuel
Published: July 2020

The paper addresses the lack of interest that Secondary Education students display towards the academic disciplines of Science, Technology, Engineering and Mathematics (STEM). From the pedagogical standpoint, the origin of this problem may lie largely in the way these subjects have predominantly been taught, i.e. using expository strategies. The aim of this paper is twofold: first, to examine the retrospective perception that preservice teachers recall about the methodologies used for teaching STEM disciplines, coupled with analysis of the value these teachers give to a number of innovative activities used to encourage interest among their future students. A second objective was to compare those perceptions with a sample of high school students’ assessment of the actual activities their teachers used in STEM disciplines. Our results revealed the predominance of traditional teaching activities in both teachers and students, although the perception of this is slightly lower among students. Practical and applied activities in laboratories and first-hand knowledge of technoscientific work were perceived as the most interesting activities, although teachers used these less frequently than other activities. Conclusions are aligned with the achievement of a range of varied and innovate learning opportunities seeking a more engaging way of teaching STEM.

Published: July 2020

La Agenda 2030 establece un marco de acción y de cambio para el conjunto de la ciudadanía. El reto de integrar dicha agenda en todos los ámbitos educativos nos lleva a cuestionarnos cómo podemos abordarlos desde la universidad. Por ello, la finalidad del presente artículo es evaluar el impacto que ha ejercido el único máster oficial que se imparte en España en Educación para el Desarrollo cuando se cumplen diez años de su implantación en nuestro país. Debe tenerse en cuenta que dichos estudios persiguen un cambio integral en el alumnado desde el enfoque de la ciudadanía crítica y el empoderamiento en la sociedad en red. Así, presentamos un análisis realizado tomando como población de estudio a los 221 estudiantes que lo han cursado hasta ahora. Los resultados se centran en las tres dimensiones esenciales: progreso académico; empleabilidad, y generación de valores y compromiso. De los datos se concluye que la evolución natural del máster ha alcanzado los tres grandes objetivos inicialmente planteados: formaciónintervención, concienciación-compromiso y acción por el cambio global.
A method for photo-identification of turtles of the Phrynops williamsi species
Authors: Bertoldi Guilherme , Hoppe Aurélio
Published: July 2020

This paper presents a method for photo-identification of Phrynops williamsi turtles. This identification is performed using shape descriptors which computationally represent the horseshoe-shaped and circular-shaped bands that can be found on the ventral surface of the turtle's head. The input image is converted to grayscale, binarized, filtered with morphologic operations, segmented based on the contours of the object and the components are selected based on their geometric characteristics. With the extraction of these characteristics, the method calculates de Fourier Descriptors and create a unique identifier used to identify the turtle from the input image. Results show that the presented method has reached a success rate of 85.71% in intra-class comparison and 85.17% in inter-class comparison.

Experimental tests of static friction coefficient for selected material combinations of expanded graphite - steel used in sealing nodes
Authors: Rewolińska Aleksandra Magdalena
Published: July 2020

The paper presents the results of static friction coefficient tests of selected material sets used in sealing nodes. Four graphite materials were tested - pure expanded graphite, expanded graphite with the addition of PTFE plastic of different densities (1.4 and 1.8 [g/cm3]) and expanded graphite laminated with austenitic steel foil - matching the steel surface. The combinations operated in a reciprocal movement. The measurements were made at different unit pressures (0.5, 2 and 5 MPa) and for different work cycles (0, 500, 1500 and 3000). On the basis of the results obtained, it was found that both the load and the number of work cycles have a significant influence on the value of the static friction coefficient of the tested materials. Not without significance is also the density of selected graphite materials. It was found that expanded graphite with PTFE and density of 1.8 g/cm3 was characterized by the lowest static friction coefficient in comparison with other materials. It is also worth noting the fact of a layer on the steel surface of combination which promotes the formation of stick-slip phenomenon.

Correction of microtia with constriction features using a superficial temporal fascial flap combined with a rib cartilage graft
Authors: Lee Joon Seok , Kim Jong Seong , Lee Jeong Woo , Choi Kang Young , Yang Jung Dug , Chung Ho Yun , Cho Byung Chae
Published: July 2020

Background Microtia with constricted features is characterized by a short helical length of variable severity, upper antihelical or scaphal deficiency, and a downfolded upper ear. No consensus has been reached regarding the most appropriate surgical method for this condition. In this study, we aimed to introduce a simple and safe surgical method for the correction or reconstruction of upper helix ear deformities.

Methods Between February 2011 and June 2014, eight patients with microtia with constricted upper helix ear deformity underwent reconstruction of the ear deformity. The upper ear helical framework was constructed by carving and curving the eighth rib cartilage harvested from the ipsilateral chest wall, covering this cartilage with a superficial temporal fascial flap, and adjusting the skin graft to align with the ear contour. To evaluate their satisfaction, patients were asked to complete a questionnaire regarding ear shape, symmetry, position, color, and overall outcome scored on a 5-point scale at 12 months postoperatively.

Results None of the patients experienced severe complications in the reconstructed ear. The preoperative and postoperative vertical ear length ratios were 0.88 and 1.02, respectively. And the mean patient satisfaction scores for shape, symmetry, position, color, and overall outcome were 4.2, 4.5, 4.7, 4.4, and 4.6 out of 5 points, respectively. All patients expressed a high level of satisfaction at 12 months postoperatively.

Conclusions Our technique provides a good alternative method for the reconstruction of moderate constricted upper helix ear deformities in patients who meet the surgical indications with satisfactory outcomes and few complications.
Use of magnetic resonance imaging for evaluation of therapeutic response in breast cancer-related lymphedema: A systematic review
Authors: Forte Antonio Jorge , Boczar Daniel , Kassis Salam , Huayllani Maria T. , McLaughlin Sarah A.
Published: July 2020

Breast cancer treatment-related lymphedema (BCRL) is a common comorbidity in breast cancer survivors. Although magnetic resonance imaging (MRI) is widely used to evaluate therapeutic response of patients with various medical conditions, it is not routinely used to evaluate lymphedema patients. We conducted a systematic review of the literature to identify studies on the use of MRI to evaluate therapy for BCRL. We hypothesized that MRI could provide information otherwise not possible through other examinations. On October 21, 2019, we conducted a systematic review on the PubMed/MEDLINE and Scopus databases, without time frame or language limitations, to identify studies on the use of MRI to evaluate therapy for BCRL. We excluded studies that investigated other applications of MRI, such as lymphedema diagnosis and surgical planning. Of 63 potential articles identified with the search, three case series fulfilled the eligibility criteria. In total, 53 patients with BCRL were included and quantitatively evaluated with MRI before and after manual lymphatic drainage. Authors used MRI or MR lymphagiography to investigate factors such as lymphatic vessel cross-sectional area, tissue water relaxation time (T2), and chemical exchange saturation transfer. The only study that compared MRI measurement with standard examinations reported that MRI added information to the therapy evaluation. MRI seems to be a promising tool for quantitative measurement of therapeutic response in patients with BCRL. However, the identified studies focused on only manual lymphatic drainage and were limited by the small numbers of patients. More studies are necessary to shed light on the topic.
Basic rheology of dermal filler

Published: July 2020

Dermal injectables are the most popular material for facial enhancement, including volumizing and wrinkle correction. However, although hyaluronic acid is the most common component of dermal injectables, the character of hyaluronic acid products is quite variable. These materials can be described in terms of their viscoelastic properties using four parameters. In this article, the author would like to describe these properties in detail. Although many physicians consider this material to be convoluted, thoroughly understanding the characteristics of various injectables enables us to tailor procedures accordingly and to enhance the final results.
L’évolution du droit international des eaux transfrontalières en Amérique du Nord
Authors: Vega Cárdenas Yenny
Published: July 2020

Les problèmes liés à la disponibilité de l’eau douce se sont intensifiés dans les dernières années. L’importance de concevoir des modèles politico-juridiques innovateurs pour la gestion et gouvernance des ressources au niveau national et international est de nos jours un enjeu majeur. C’est dans ce contexte que nous analyserons l’évolution du droit international des eaux transfrontalières en Amérique du Nord, notamment par rapport à l’évolution des relations entre le Canada et les États-Unis ainsi qu’entre les États-Unis et le Mexique. Nous observerons que les tensions, négociations et solutions retenues pour la distribution de l’eau diffèrent fortement au sein même du continent, des réalités qui reflètent la double rationalité concernant la gestion des ressources hydriques partagées. Nous présenterons plus précisément l’opposition entre ceux en faveur de la création de nouveaux marchés de l’eau et ceux qui encouragent la préservation de l’eau et de l’environnement.

Published: July 2020

Despite the many reconstructions of fossil material that have recently appeared in the literature, dinosaur eggshells have never been reconstructed using computing techniques. Using the EMAC 3-D modelling methodology, we reconstruct a section of the Late Cretaceous Megaloolithus siruguei eggshell, which has a particularly complex pore system, exhibiting an intricate network of vertical, oblique, and horizontal pores
Conohyus simorrensis (Lartet, 1851) (Suidae, Mammalia) from the Middle Miocene of Carpetana (Madrid, Spain)
Authors: Pickford Martin
Published: July 2020

Fossil suid remains excavated from Middle Miocene deposits at Carpetana, Madrid, comprise mandibles and isolated teeth of the tetraconodont suid, Conohyus simorrensis (Lartet, 1851). The Carpetana mandible is the most complete specimen known for the genus and throws a great deal of light on the morphology of the anterior dentition. Heavy wear on all the teeth, including deciduous ones in the sample, indicates a diet of abrasive or durable food items such as nuts

One of the most important contributions of Nieves López Martínez in Palaeobiogeography is the study of the ‘centre of origin of species’ concept and the proposal of the ‘Asymmetric Time Model’ as an alternative to the ‘Symmetric Time Model’, a key concept in dispersalist Historical Biogeography. As a consequence of these ideas, she discussed the methodology to establish biostratigraphic scales, pointing out that the higher number of ‘First Appearance Datum’ (FADs) over that of ‘Last Appearance Datum’ (LADs) in the fossil record supports the Asymmetrical Time Model. In this study we analyse the middle Miocene micromammal appearance and extinction events (FADs and LADs) based on well-calibrated local biostratigraphic scales from different European basins, in order to determine which of the proposed biogeographical models better fits the Miocene European micromammal record. The results support that the Asymmetric Time Model of palaeobiogeography is only applicable in rare cases. The analysed fossil record only shows one event of occurrence and one of extinction that can be considered synchronous at continental level. Finally, the implications of the biogeographic models in the proposition of biochronologic continental scales are also discussed, pointing out that palaeobiogeographic frameworks need robust biochronologies based on extensive local biostratigraphic data with independent temporal correlation
Neural dynamics of perceptual inference and its reversal during imagery
Authors: Dijkstra Nadine , Ambrogioni Luca , Vidaurre Diego , van Gerven Marcel
Published: July 2020

After the presentation of a visual stimulus, neural processing cascades from low-level sensory areas to increasingly abstract representations in higher-level areas. It is often hypothesised that a reversal in neural processing underlies the generation of mental images as abstract representations are used to construct sensory representations in the absence of sensory input. According to predictive processing theories, such reversed processing also plays a central role in later stages of perception. Direct experimental evidence of reversals in neural information flow has been missing. Here, we used a combination of machine learning and magnetoencephalography to characterise neural dynamics in humans. We provide direct evidence for a reversal of the perceptual feed-forward cascade during imagery and show that, during perception, such reversals alternate with feed-forward processing in an 11 Hz oscillatory pattern. Together, these results show how common feedback processes support both veridical perception and mental imagery.

Cannabinoid CB2 receptor (CB2) agonists are potential analgesics void of psychotropic effects. Peripheral immune cells, neurons and glia express CB2; however, the involvement of CB2 from these cells in neuropathic pain remains unresolved. We explored spontaneous neuropathic pain through on-demand self-administration of the selective CB2 agonist JWH133 in wild-type and knockout mice lacking CB2 in neurons, monocytes or constitutively. Operant self-administration reflected drug-taking to alleviate spontaneous pain, nociceptive and affective manifestations. While constitutive deletion of CB2 disrupted JWH133-taking behavior, this behavior was not modified in monocyte-specific CB2 knockouts and was increased in mice defective in neuronal CB2 knockouts suggestive of increased spontaneous pain. Interestingly, CB2-positive lymphocytes infiltrated the injured nerve and possible CB2transfer from immune cells to neurons was found. Lymphocyte CB2depletion also exacerbated JWH133 self-administration and inhibited antinociception. This work identifies a simultaneous activity of neuronal and lymphoid CB2that protects against spontaneous and evoked neuropathic pain.
Persistent firing in LEC III neurons is differentially modulated by learning and aging

Published: July 2020

Whether and how persistent firing in lateral entorhinal cortex layer III (LEC III) supports temporal associative learning is still unknown. In this study, persistent firing was evoked in vitro from LEC III neurons from young and aged rats that were behaviorally naive or trained on trace eyeblink conditioning. Persistent firing ability from neurons from behaviorally naive aged rats was lower compared to neurons from young rats. Neurons from learning impaired aged animals also exhibited reduced persistent firing capacity, which may contribute to aging-related learning impairments. Successful acquisition of the trace eyeblink task, however, increased persistent firing ability in both young and aged rats. These changes in persistent firing ability are due to changes to the afterdepolarization, which may in turn be modulated by the postburst afterhyperpolarization. Together, these data indicate that successful learning increases persistent firing ability and decreases in persistent firing ability contribute to learning impairments in aging.

Hippocampal firing is organized in theta sequences controlled by internal memory processes and by external sensory cues, but how these computations are coordinated is not fully understood. Although theta activity is commonly studied as a unique coherent oscillation, it is the result of complex interactions between different rhythm generators. Here, by separating hippocampal theta activity in three different current generators, we found epochs with variable theta frequency and phase coupling, suggesting flexible interactions between theta generators. We found that epochs of highly synchronized theta rhythmicity preferentially occurred during behavioral tasks requiring coordination between internal memory representations and incoming sensory information. In addition, we found that gamma oscillations were associated with specific theta generators and the strength of theta-gamma coupling predicted the synchronization between theta generators. We propose a mechanism for segregating or integrating hippocampal computations based on the flexible coordination of different theta frameworks to accommodate the cognitive needs.

Foxp3+ regulatory T cells (Tregs) are potent suppressor cells, essential for the maintenance of immune homeostasis. Most Tregs develop in the thymus and are then released into the immune periphery. However, some Tregs populate the thymus and constitute a major subset of yet poorly understood cells. Here we describe a subset of thymus recirculating IL18R+ Tregs with molecular characteristics highly reminiscent of tissue-resident effector Tregs. Moreover, we show that IL18R+ Tregs are endowed with higher capacity to populate the thymus than their IL18R– or IL18R–/– counterparts, highlighting the key role of IL18R in this process. Finally, we demonstrate that IL18 signaling is critical for the induction of the key thymus-homing chemokine receptor – CCR6 on Tregs. Collectively, this study provides a detailed characterization of the mature Treg subsets in the mouse thymus and identifies a key role of IL18 signaling in controlling the CCR6-CCL20-dependent migration of Tregs into the thymus.
