Published: December 2020

O estudo aqui apresentado guarda relação com a temática estatística e educação e está circunscrito no campo da história da educação profissional, pois se situa no contexto da Lei 5.692/1971, que transformou em profissional o ensino secundário no Brasil. Este estudo tem como objetivo fazer análise do referencial epistemológico, teórico e metodológico nas fontes nominadas Mensagens Presidenciais ao Congresso Nacional, refletindo sobre as estatísticas do ensino de 2° grau no Brasil. A intenção é demonstrar a utilização de um discurso em que os números tratados de maneira naturalizada servem como manutenção da ferramenta de manipulação social. A metodologia utilizada foi a revisão bibliográfica e análise documental. Para compreender o objeto de estudo, questionamos: Qual a relação entre a epistemologia e as estatísticas educacionais? Como as estatísticas do ensino de 2º grau são apresentadas nas Mensagens Presidenciais ao Congresso Nacional. Na intenção de compreendermos esses aspectos, fazemos uso de conceitos como obstáculo epistemológico de Gaston Bachelard (1996), História política de René Rémond (2003), História Serial de Pierre Chaunu (1976) e José D’Assunção Barros (2004). Também refletimos acerca da construção da história da ciência numa perspectiva histórica e sobre relações de poder, baseadas em autores como Michel Foucault (2002), Thomas Kuhn (1987) e Gaston Bachelard (1996). Os resultados obtidos demonstram que o uso das estatísticas educacionais se apresenta, nas fontes estudadas, de maneira que o leitor não questione as informações, mesmo que divirjam ou demonstrem dados que fujam da realidade, pois existe um discurso que dificulta essas indagações.

Authors: Brito Leonardo Leonidas
Published: December 2020

O artigo em tela apresenta-se como uma primeira possibilidade, no campo de estudos da Educação profissional e tecnológica (EPT), de diálogo e reflexão estritamente teórica acerca da questão da politecnia da aprendizagem e da centralidade do trabalho a partir da tradição inaugurada pelos socialistas libertários em meados do século XIX. Especificamente, tomando como referência os escritos do filósofo social francês Pierre Joseph Proudhon, que inaugurou, a partir de 1840, o que se convencionou chamar de anarquismo. Corrente do movimento socialista dos trabalhadores europeus no século XIX marcada por original, radical e consistente crítica às formas de dominação erigidas pelo modelo capitalista industrial advindo das transformações disruptivas históricas ocorridas no século XVIII.

Objectives: To examine the effect of two aging protocols on the chemical and phase composition as well as the surface state of monolithic translucent zirconia ceramics. Material and Methods: Translucent zirconia ceramics KATANA-Zirconia STML with different surface treatments (no treatment, K1, K2; glazed, G1-G8; polished, P1-P8) underwent testing in order to examine how the two aging protocols (three-hour hydrothermal degradation in an autoclave at 134 °C and 2 bars: G1-G4, P1-P4, and sixteen-hour chemical degradation in four-percent acetic acid at 80 °C (ISO 6872): G5-G8, P5-P8) affect chemical composition, particularly the share of stabilizing yttrium oxide (Energy Dispersive XRay Fluorescence – EDXRF), phase composition (X-ray diffraction – XRD) and surface state in terms of roughness and gloss. Results: Aging protocols did not affect the tested chemical composition stability of specimens and a high share of stabilizing yttrium-oxide (≥10% of total content), which correlates with the absence of monoclinic phase. A decrease in gloss on all specimens is statistically significant. Chemical degradation substantially increased the surface roughness of tested specimens. Conclusions: Translucent monolithic zirconia demonstrated a stable chemical composition and resistance to tetragonal-to-monoclinic transformation. Surface gloss was significantly reduced, especially in polished specimens. Contrary to glazed specimens, the tested polished specimens manifested an increase in surface roughness. Glazing the surface of translucent monolithic zirconia produces better esthetic, tribological and hygienic effects than polishing.

Published: December 2020

ABSTRACT Background: Colorectal cancer (CRC) is one of the most common types of cancer in the world. Over time, intestinal epithelial cells undergo mutations that may lead to proliferative advantage and the emergence of cancer. Mutations in the beta-catenin pathway are amongst those described in the development of CRC. Aim: To verify the existence of a relation between the presence of Wnt3, beta-catenin and CDX2 in colorectal cancer samples and clinical outcomes such as disease progression or death. Method: Wnt3a, beta-catenin and CDX2 immunohistochemistry was performed on CRC tissue microarray samples (n=122), and analysis regarding the relation between biomarker expression and disease progression or death was performed. Results: No significant difference was found between the presence or absence of CDX2, beta-catenin or Wnt3a expression and clinical stage, tumor grade, disease progression or death. Conclusion: CDX2, beta-catenin and Wnt3a are not useful to predict prognosis in patients with CRC.

Authors: LIMA Agnaldo Soares , PEREIRA Bárbara Buitrago , JUNGMANN Sven , MACHADO Carla Jorge , CORREIA Maria Isabel Toulson Davison
Published: December 2020

ABSTRACT Background - Biliary complications (BC) represent the most frequent complication after liver transplantation, up to 34% of cases. Aim: To identify modifiable risk factors to biliary complications after liver transplantation, essential to decrease morbidity. Method: Clinical data, anatomical characteristics of recipient and donors, and transplant operation features of 306 transplants with full arterial patency were collected to identify risk factors associated with BC. Results: BC occurred in 22.9% after 126 days (median) post-transplantation. In univariate analyses group 1 (without BC, n=236) and group 2 patients (with BC, n=70) did not differ on their general characteristics. BC were related to recipient age under 40y (p=0.029), CMV infection (p=0.021), biliary disease as transplant indication (p=0.018), lower pre-transplant INR (p=0.009), and bile duct diameter <3 mm (p=0.033). CMV infections occurred sooner in patients with postoperative biliary complications vs. control (p=0.07). In a multivariate analysis, only CMV infection, lower INR, and shorter bile duct diameter correlated with BC. Positive CMV antigenemia correlated with biliary complications, even when titers lied below the treatment threshold. Conclusions: Biliary complications after liver transplantation correlated with low recipient INR before operation, bile duct diameter <3 mm, and positive antigenemia for CMV or disease manifestation. As the only modifiable risk factor, routine preemptive CMV inhibition is suggested to diminish biliary morbidity after liver transplant.

Published: December 2020

Resumo Baseando-se na perspectiva teórica da transferência de conhecimento interorganizacional, este estudo teve como objetivo analisar o papel dos mecanismos no desempenho da transferência de conhecimento entre uma instituição brasileira de pesquisa pública e suas empresas licenciadas. Em termos metodológicos, foi realizada pesquisa de natureza qualitativa com base no método de estudo de caso aplicado na maior instituição pública de pesquisa agropecuária do Brasil. Os resultados do estudo apontam que, a despeito da diversidade de mecanismos disponíveis, a transferência de conhecimento entre a instituição de pesquisa e as empresas licenciadas é caracterizada pelo uso intensivo de mecanismos de codificação ao invés de mecanismos de personalização, os quais são fundamentais na transferência de conhecimento tácito. Tais achados convergem com estudos na área que sinalizam que o compartilhamento de conhecimento tácito requer o uso de mecanismos de personalização e que, na ausência de mecanismos adequados, a transferência tecnológica tende a enfrentar desafios consideráveis, como a emergência de conflitos relacionais entre as partes e a dificuldade de aplicação da tecnologia pelas empresas receptoras, inibindo o potencial de inovação do processo. Portanto uma implicação relevante é a de que a transferência de conhecimento interorganizacional deve ser concebida como um processo relacional que requer aprendizagem conjunta, sobretudo, quando o tipo de conhecimento envolvido possui natureza complexa.

UM NARRADOR DO SEGUNDO ESCALÃO
Authors: BOUCINHAS ANDRÉ DUTRA
Published: December 2020

Resumo No artigo, identifica-se o perfil socioeconômico do conselheiro Aires, personagem que "escreveu" os diários que se transformaram no romance Memorial de Aires e que serviram de base para a narrativa, também composta por Aires, publicada com o título Esaú e Jacó. A partir dessa identificação, evidencia-se como a escolha de um funcionário de segundo escalão da burocracia imperial, para suposto autor dessas obras, serviu ao propósito de Machado de Assis de criticar a ausência de mudanças sociais significativas ocorridas no período republicano e a manutenção de uma estrutura de poder excludente semelhante à existente durante a Monarquia.
Shear friction capacity of self-consolidating concrete
Authors: Savaris Gustavo , Pinto Roberto Caldas de Andrade
Published: December 2020

Abstract An experimental research was developed to evaluate shear transfer in self-consolidating. Three concrete mixes were prepared, one conventional and two self-consolidating, differing on the proportion of the coarse and fine aggregate used. Nine push-off specimens, containing steel reinforcement passing through the shear plane, were tested, to evaluate the ultimate shear stress and shear plane displacements. Shear strength of self-consolidating concrete specimens were higher than conventionally vibrated concrete. The experimental results were compared to the shear strength estimated by literature and code based equations, yielding conservative results of these equations for both types of concrete, especially the models that disregard the compressive strength of concretes.
Numerical analysis of the influence of block geometry on the behavior of piled foundations
Authors: Garcia Jean Rodrigo , Albuquerque Paulo José Rocha de
Published: December 2020

abstract: In recent years, engineering has significantly increased the use of numerical modeling, mainly applied in studies of solutions and analysis of the behavior of the soil - structure and foundation element interaction. In this sense, this paper analyzes the behavior of blocks foundations made up of one, two, three and four piles with 25 cm in diameter (d) and 5 m in length (L) and with unusual spacing between the piles, equal to 5d in a three-dimensional finite element numerical model (MEF-3D). The results of the numerical analyzes demonstrated an average contribution of 36% due to the block-to-ground contact in relation to the total capacity of the system. The geometry of the block influences the response in terms of load capacity and stiffness of the foundation element. These results demonstrate an opportunity to reevaluate traditional calculation requirements, with the aim of rationalizing the design of foundations, thus improving the safety of the structural system.
Geographic Patterns In Pollen Production In The Plant Ring SpeciesEuphorbia tithymaloidesIn The Caribbean
Authors: Cacho N. Ivalú , José-Zacatula Daniel
Published: December 2020

Abstract—We examine investment in male function in the context of geography and floral morphology in the plant ring speciesEuphorbia tithymaloides, which colonized the Caribbean from Mexico/Guatemala along two fronts that roughly correspond to the Greater and the Lesser Antilles and that meet in the vicinity of the Anegada Passage. Our results on investment in pollen relative to ovule production are consistent withE. tithymaloidesrelying on pollinators for reproduction across its range in the Caribbean. We document a geographic pattern of reduction in anther number and pollen:ovule ratios in populations ofE. tithymaloidestowards the Anegada Passage, which is consistent with a possible geographic transition towards a mixed breeding system where selfing has increased importance in this area where its two expansion fronts meet. The reduction in pollen production is correlated with inflorescence morphology, which converges to relatively shorter cyathia towards the Anegada Passage along both fronts. We discuss alternative scenarios and potential drivers of the patterns we document.

Authors: Cervantes Angélica , Rojas-Martínez Cecilia , Flores-Olvera Hilda , Ochoterena Helga
Published: December 2020

Abstract—The recent rediscovery of Jatropha riojae, which was considered as probably extinct, led to a taxonomic re-evaluation of the species due to its problematic circumscription with respect to morphologically similar species of Jatropha section Loureira
subsect. Loureira. Based on our study, J. riojae is accepted, taxonomic clarifications are made, including the designation of a lectotype for the name, a complete description of vegetative and reproductive structures is provided, and the species is illustrated and compared to
others with which it has been confused. The geographical distribution of J. riojae is clarified as endemic to the municipality of Acatlán, Puebla, Mexico in the south of the Balsas River Basin. To determine the conservation status of the species, the risk assessment method of
the Mexican Red List (NOM 059-SEMARNAT-2010) was applied, indicating that J. riojae should be assigned to the “Endangered” category. A re-evaluation of the species under the IUCN criteria indicated that it should be assigned in the “Critically Endangered”
(CR) category.

The Portrait of a Scientist in the Light of Synergetics
Authors: Budjakova Tatyana , Goricheva Vlasta
Published: December 2020

The article is devoted to an outstanding Russian criminologist Yuri Vladimirovich Golik. Yu.V. Golik, being a creative person, drew attention to one of the trends of modern world science - synergetics - at the beginning of his scientific career. The synergetic approach means a fundamentally new view of the development of nature and society, in contrast to classical paradigms in science. The young scientist was attracted by the interdisciplinary character of synergetics. Later, in his work «Synergetics and Crime», he singled out the main parameters of the synergetic approach important for criminology: interaction that generates a new quality; self-organization of open systems with nonlinear feedbacks, including understanding of crime in the light of synergetic approach as an open self-organizing system, etc. The main stages of the life of Yu.V. Golik are indirectly related to synergistic principles in one way or another. His graduation thesis, and then his Ph.D. thesis, are devoted to the problem of an accidental criminal. Accidentality was considered by the author from a synergetic point of view as a way of comprehending internally hidden regularities. Engaging in the fight against corruption, Yu.V. Golik also draws attention to a need for non-traditional approaches, both to study it and to eradicate it. In a monograph written in co-authorship with V.I. Karasev, «Corruption as a Mechanism of Social Degradation», a paradoxical conclusion is made, in a spirit of synergetics, that a change in legal reality not only mobilizes socially-organized population to solve radically new global problems, but also objectively contributes to socially dangerous behavior. Such a warning is important for developing adequate means of crime prevention even at the stage of designing legal reforms. Synergetic principles were applied by Yu.V. Golik in his doctoral dissertation «Positive stimuli in criminal law (concept, content, prospects)». Yuriy Vladimirovich publically discussed such unusual law regulation issues as the consequences of positive incentives, the «boundlessness» of positive incentives in contrast to the limited nature of negative incentives, etc. Against the backdrop of doubts raised by some scholars about the appropriateness of the synergetic approach in social sciences and, in particular, in law, it should be noted that the synergy of Yu.V. Golik was justifiably applied in those times when a new unconventional understanding of social and legal reality was required.
From Extraordinary Law to “Revolutionary Legality”: Formation of the Concept of Revolutionary Law in the Soviet Legal Doctrine
Authors:   Tambov State Technical University, Tambov, Russia, Nikulin V. V.
Published: December 2020

The main provisions of the concept of “revolutionary legality” in the Soviet legal doctrine are analyzed; theoretical and practical aspects of its formation, factors that influenced its content are considered. It is argued that the defining function of the concept of “revolutionary legality” is the function of achieving the political goals of the state by legal means. It is concluded that the concept of “revolutionary legality” was a special system of law, adapted to the ideological tasks of socialist construction. It embodied the gap between formal law and the actual functioning of Soviet legal institutions, which constantly existed in the Soviet legal system. It is concluded that the concept of “revolutionary legality” was not a complete condemnatory legal construction, but a modification of the previously existing one-sided orientation of law to a political doctrine, which made it possible to interpret “revolutionary legality” in a variety of ways in practical legal activity, giving and strengthening certain aspects necessary for solving ideological and practical problems.
Forms of Prosecutor’s Work in Ruling of Criminal Case Termination (Criminal Prosecution)
Authors:   Saratov State Law Academy, Saratov, Russia, Lavnov M. A.
Published: December 2020

Using the accumulated international research experience, as well as developments related to criminal procedure law branches, the article examines a number of issues related to the implementation of one of the forms of resolving a criminal legal conflict, namely, the criminal case termination (criminal prosecution). The problem is analyzed through the prism of the model of Prosecutor's work as the central subject of criminal prosecution, while protecting the legality and ensuring the rights of an individual in criminal proceedings. The lack of a unified concept and the lack of agreement on “reformative” transformations of criminal proceedings directly affect both the procedural status of the Prosecutor and all institutions of criminal procedure law. The research revealed the incomplete status of the Prosecutor and indicate the prospects for building an effective procedural model of Prosecutor's work in criminal proceedings.

Mastitis, somatic cell count, and its impact on dairy-product quality… An omission in Colombia?: A review
Authors: Riveros-Galán David S , Obando-Chaves Mónica
Published: December 2020

Mastitis is the most common disease in dairy herds and the main cause of economic losses in milk production worldwide. This inflammatory reaction of the mammary gland affects the quantity, composition and quality of milk produced and its suitability for the dairy industry. Despite of its importance, Colombia has no regulations on somatic cell count (SCC); that is, no official upper limits have been established for the dairy industry. The current quality-based payment system for raw milk does not encourage local producers to reduce the level of somatic cells. Consequently, Colombia is at a disadvantage compared to countries that include this parameter in their payment schemes and subscribe to international free trade agreements, affecting the competitiveness of the Colombian dairy sector. This article reviews the types of somatic cells, the microbiology of mastitis, its etiology and diagnosis, the changes that generate the composition of milk, and the impact of high SCCs on the quality of dairy products, such as yogurt, cheese, and milk powder. The final section offers a reflection on the problem of high SCCs in Colombia and the lack of regulations in this regard.

Background: The use of pequi by-product as animal feed is an appealing alternative to reduce overall production costs. However, little is known regarding its effects on animal performance as well as the ideal inclusion level in the diet. Objective: To evaluate performance, intake, and digestibility of confined lambs receiving diets containing different levels of pequi byproduct as a partial substitute for corn silage. Methods: The experiment was conducted in Curvelo, Brazil, using twenty-five crossbred Santa Inês male lambs (17.83 ± 1.73 kg) aged six months for 92 days. Increasing levels of pequi by-product (0, 6, 12, 18, and 24%) replacing corn silage were evaluated in a completely randomized design. Analysis of variance and regression were performed, with 5% significance level. Results: Inclusion of pequi by-product did not influence (p>0.05) average daily gain, total weight gain, or feed conversion ratio. No effect (p>0.05) was also observed on intake of dry matter, organic matter, ether extract, crude protein, neutral detergent fiber, total carbohydrates, and total digestible nutrients. However, a linear decrease was observed (p<0.05) in the apparent digestibility of dry matter, organic matter, ether extract, crude protein, neutral detergent fiber, total carbohydrates, and total digestible nutrients with increasing inclusion of pequi by-product. Conclusion: Pequi by-product is a potential substitute for corn silage in lamb diets because it does not influence animal performance and feed intake. However, digestibility decreases with increasing dietary inclusion levels of pequi by-product.
Effective Morphological Transformation and Sub-pixel Classification of Clustered Images
Authors: Rajesh B. Naga
Published: December 2020

The main aim of this research work is to perform the morphological operations with reduced time complexity and area complexity. Morphological operation is the key element in any image processing. Finding the maximum and minimum using a window of defined size will imply to the morphological dilation and erosion respectively. So the proposed algorithm should be fast in the comparison and sorting, this way the time complexity could be reduced. It’s believed that the anchor concept will fetch this cause. The idea behind this is it fixes a pixel and setting it as the center pixel all the surrounding pixels will be processed. Moreover this is now been implemented for rectangular structuring element. This paper attempts the same for flat and 3D structuring elements. Hyper-spectral Imaging is a developing zone of remote detecting applications. Hyper-spectral pictures incorporate more extravagant and better otherworldly data than the multi-spectral pictures got previously. Hyper-otherworldly pictures are described by an exchange off between the unearthly and spatial resolution. The principle issue of the hyper-ghostly information is the generally low spatial goal. For arrangement, the serious issue brought about by low spatial goal is the blended pixels. Blended pixels alluded to the pixels which are involved by more than one land spread class. In the proposed procedure another strategy is utilized to address the issue of blended pixels and to get a better spatial goal of the land spread characterization maps. The strategy misuses the upsides of both picture bunching methods and phantom dimming calculations, so as to decide the fragmentary plenitudes of the classes at a sub-pixel scale. Spatial regularization by Flank planning method is at last performed to spatially find the got classes at sub-pixel level.
Clima, salud pública y sociedad: causas, gestión y efectos de la fiebre amarilla en la Barcelona de 1821
Authors: Pometti Benítez Kevin
Published: December 2020

RESUMENLa epidemia de fiebre amarilla que tuvo lugar en Barcelona en 1821 estuvo condicionada por la confluencia de causas endógenas y exógenas, ambientales y humanas, que fueron favorables al arraigo de una epidemia importada que generó serias repercusiones sobre la sociedad de su época. Por este motivo, en este artículo analizamos las particularidades del contexto ambiental que precedieron al inicio de la epidemia y que imperaron marcando las pautas propicias tanto para su desarrollo como para su progresiva extinción atendiendo, además, a lascondiciones de insalubridad que imperaban en la urbe. Por otra parte, centramos nuestra atención en las medidas que se implementaron en materia de salud pública para la gestión epidémica tanto para detectar su efectividad como sus repercusiones a nivel social, institucional, económico. Otro punto de interés reside en contrastar las condicionesambientales con las defunciones registradas en los puntos de observación habilitados para la contención de las personas infectadas por la fiebre amarilla.PALABRAS CLAVEFiebre amarilla, Barcelona, enfermedades vectoriales, salud pública, epidemias, clima. TITLEClimate, public health and society: causes, management and effects of Yellow Fever epidemic in Barcelona in 1821ABSTRACTThe Yellow Fever epidemic that took place in Barcelona in 1821 was a consequence of the confluence of endogenous and exogenous factors, human and environmental causes, which were favourable for the development of an imported disease that had deleterious effects over the society at that time. Because of that, in this paper we analyse the particularities of the environmental context that preceded the start of the epidemic and during its prevalence. Attending also to the insalubrity causes that characterized the city. Moreover, we centre our attention into analysing the sanitation politics applied by the authorities and medical institutions to evaluate the effectivity of those measures and to detect the repercussions over the society, the institutions and the economy. Another point of interest resides in to contrast the environmental conditions with the dead reports recovered from the observation points fitted out by authorities to contain the people affected by the epidemic.KEY WORDSYellow Fever, Barcelona, Vector Diseases, Public Health, Epidemics, Climate.
Por el bien de la patria: la obra del magistrado José de Olmeda y León (1740-1805) y su percepción de España
Authors: Soriano Muñoz Núria
Published: December 2020

RESUMENEste artículo analiza la obra del jurista madrileño José de Olmeda y León (1740-1805). Sus aportaciones, analizadas por la historiografía desde el punto de vista del derecho, se interpretan como contribución a la construcción del imaginario nacional y la configuración de una memoria cultural de España. El magistrado —colegial mayor de Salamanca, oficial de la Audiencia de Sevilla desde 1778 y miembro de la Real Sociedad de Madrid desde 1779— dedicó su vida a la escritura de traducciones y tratados, siendo los «Elementos del derecho público» (1771) su publicación más célebre. Tras realizar un repaso por su trayectoria biográfica y situar su escritura en el debate sobre los «caracteres nacionales» y la defensa de España, mi objetivo es analizar cómo el autor percibe el pasado y fija su valor como reconocimiento identitario. Su aportación individual, vinculada otros textos —como el de José de Cadalso— permite comprender la complejidad de las diversas perspectivas que integran el movimiento apologético y crítico de España en la segunda mitad del siglo.PALABRAS CLAVEJosé de Olmeda y León, nación, pasado, memoria cultural, representaciones, identidad nacional. TITLEFor the good of the fatherland: The work of magistrate José Olmeda y León (1740-1805) and his perception of SpainABSTRACTThis article analyzes the work of the jurist José Olmeda y León (1740-1805). The magistrate —official of the Audience of Seville since 1778 and member of the Royal Society of Madrid since 1779— dedicated his life to the writing of translations and treaties, being «Elementos del derecho público» (1771) its publication most celebrated. His contributions, mainly analyzed by historiography from the point of view of law, are interpreted as a contribution to the construction of the national imaginary and the configuration of a shared cultural memory. After reviewing his biographical trajectory and contextualizing his writing, my objective is to analyze how the author perceives the past and fixes its value as an identity recognition. His individual contribution, linked to other texts, such as that of his colleague José de Cadalso, allows us to understand the complexity and breadth of the diverse perspectives that make up the apologetic movement of the second half of the 18th century.KEY WORDSJosé de Olmeda y León, nation, past, cultural memory, representations, national identity.

Resumo: O artigo se propõe a analisar o romance Mar morto (1936), do escritor brasileiro de origem baiana Jorge Amado, e a obra Le gang des Antillais (1985), do autor francês de origem martinicana Loïc Léry. Leitor de Amado, Léry compartilha com o mesmo o apreço por temáticas sociais, pela escrita engajada, pela militância política e a experiência do exílio e do encarceramento. No âmbito literário, os livros dos autores, a despeito de distintas envergaduras literárias, apresentam imaginários convergentes na leitura do binômio ‘vulnerabilidade social’ e ‘banditismo’ e apontam para a criminalidade como ápice de opressões sociais e históricas que fragilizam seres marginais.Palavras-chave: Jorge Amado; Loïc Léry; literatura comparada; vulnerabilidade social; criminalidade.Abstract: The article aims to analyze the novel Sea of Death (1936) by the Brazilian writer, of Bahian origin, Jorge Amado and the work Le gang des Antillais (1985), by the French author, of Martinican origin, Loïc Léry. Reader of Amado, Léry shares with him the appreciation for social themes, the engaged writing, the political militancy and the experience of exile and incarceration. In the literary sphere, their books, despite different literary wingspans, present convergent imaginaries in the reading of the binomial ‘social vulnerability’ and ‘banditism’ and point to crime as the apex of social and historical oppressions that weaken marginal beings.Keywords: Jorge Amado; Loïc Léry; comparative literature; social vulnerability; criminality.

Published: December 2020

Resumo: O presente artigo tem por objetivo analisar a relevância do Vodu na obra País sem chapéu, de Dany Laferrière, publicada em 1996, no Quebec. Essa obra retrata a história do personagem Vieux Os que retorna ao seu país natal, após vinte anos de exílio, com a intenção de escrever um livro. A partir de um forte estranhamento inicial, Vieux Os propõe uma série de reflexões sobre a vida cotidiana e o imaginário cultural, com a intenção de trabalhar e problematizar a identidade espiritual ancestral de seu país. Vamos investigar em que medida esse reencontro do narrador-personagem com seu país natal é revelador quanto à importância do Vodu em sua própria vida e no mundo social haitiano. Para alcançar o nosso objetivo, estabeleceremos um diálogo entre País sem chapéu (1996), Dany Laferrière: autobiografia, ficção ou autoficção? (2007) de Eurídice Figueiredo e Vodu no Haiti – Candomblé no Brasil: Identidades culturais e sistemas religiosos como concepções de mundo afro-latino americano (2010) de Handerson Joseph.Palavras-chave: Dany Laferrière; País sem chapéu; Vodu; romance.Abstract: This article intends to analyze the relevance of the Voodoo in Dany Laferrière’s work País sem chapéu, published in 1996 in Quebec. This work portrays the story of Vieux Os who returns to his home country after twenty years of exile with the intention of writing a book. From a strong initial strangeness, Vieux Os proposes a series of reflections about daily life and the cultural imaginary with the intention of discussing and problematizing the country’s ancestral spiritual identity. We are going to investigate to what extent this reunion of the first-person narrator with his native country is revealing the importance of the Voodoo in his own life and in the Haitian’s social world. To achieve our goal, we are going to establish a dialogue between País sem chapéu (1996), Dany Laferrière: autobiografia, ficção ou autoficção? (2007) by Eurídice Figueiredo and Vodu no Haiti – Candomblé no Brasil: identidades culturais e sistemas religiosos como concepções de mundo afro-latino americano (2010) by Handerson Joseph.Keywords: Dany Laferrière; País sem chapéu; Voodoo; novel.
Inequality and female labour force participation in West Africa

This study examined the impact of income inequality on female labour force participation in West Africa for the period 2004 to 2016. The study employed the Gini coefficient, the Atkinson index and the Palma ratio as measures of income inequality. For robustness, the study also utilises female employment and female unemployment as measures of female labour force participation. The study employed the instrumental variable fixed effects model with Driscoll and Kraay standard errors to account for simultaneity/reverse causality, serial correlation, groupwise heteroskedasticity and cross-sectional dependence. The empirical results reveal that the three measures of income inequality significantly reduce the participation of women in the labour force in West Africa. The study also revealed that domestic credit, remittances and female education are positively associated with female labour force participation in the sub-region. Further findings reveal that economic development reduces the participation of women in the labour force in West Africa with the U-shaped feminisation theory not valid for the West African region. The study, however, revealed an inverted U-shaped relationship between inequality and female unemployment. Policy recommendations based on these findings are discussed.

Low- and middle-income countries have limited health resources, which contribute to high morbidity and mortality from non-communicable diseases, such as diabetes and hypertension. As the prevalence of diabetes and hypertension is expected to increase globally, sub-Saharan African countries, such as Nigeria, will be most affected. Medical missions can play a critical role in achieving non-governmental organizations’ goal of ensuring healthy lives by improving healthcare access for vulnerable populations. Medical missions are defined as travel by trained medical professionals, including nurses, to foreign countries, with a specific medical purpose for a designated period of time, ranging from one week to years, depending on the organization. Using a narrative inquiry approach, we describe a collaborative, community-engaged medical mission in rural southeastern Nigeria aimed at increasing access to care for non-communicable diseases and improving self-management. Through annual intensive medical missions (lasting one to three days each year) from 2004-2018, we provided 39 service days for 7,376 children and adults (male = 1,636; females = 4,802) from 23 surrounding communities. This included conducting 50 cataract surgeries, distributing 3000 reading glasses, and providing follow-up care as needed. The prevalence of diabetes and hypertension was high. Other common health conditions included malaria, osteoarthritis, and eye diseases. Our medical missions addressed unmet health needs for non-communicable diseases and maintained year-round, weekly, follow-up clinics. Community engagement and stakeholder involvement contributed to the sustainability of our medical mission project. Additional work is needed to monitor health outcomes prospectively, evaluate the impact of our medical mission, and create a cost-effective and sustainable model to improve the health of this population.

Pursuing Peace Amidst the Mass Incarceration of Black Males
Authors: Wallace James
Published: December 2020

There can be no peace in this nation without first addressing the crisis of massincarceration among Black males. To address this concern, it is necessary toexplore the experiences of those affected through community engaged research andinvolve these individuals in developing solutions to address this problem. I am agraduate student in the IU School of Education at IUPUI pursuing a doctorate inUrban Studies. I am studying about the impacts on communities when Black boysare poorly educated in leaky K-12 pipelines and grow up to be disproportionatelyincarcerated. My research asks, what were the motivations, barriers and resourcesimpacting the experiences of African American males who were incarcerated andthen decide to pursue an education after they have been released into ourcommunities. I want to know in what ways does achieving more education, gettinga high school diploma or a bachelor’s degree, affect their lives and ourcommunities? Community engaged and community based participatoryresearchers need to ask questions about the effects of this phenomenon.
Breve 20: Planes de beneficios en salud y financiamiento basado en resultados: Dos aliados para la cobertura universal y efectiva en salud
Authors: Sabignoso Martín
Published: December 2020

El presente Breve repasa la experiencia latinoamericana en la utilización combinada de los Planes de Beneficios en Salud (PBS) y el Financiamiento Basado en Resultados (FBR) e intenta responder a las siguientes preguntas: ¿por qué es clave una vinculación directa y explícita entre el PBS y el FBR?, ¿cómo pueden potenciarse recíprocamente?, ¿por qué ambos instrumentos son fundamentales para el desarrollo de la poco aprovechada función de “compra estratégica” de servicios de salud? Y, por último, ¿cuáles son las oportunidades y los retos que se presentan para un uso coherente de estas poderosas palancas de transformación de los sistemas de salud?
