A geometria nos anos finais do Ensino Fundamental: uma análise de referenciais curriculares sob a perspectiva do enfoque ontossemiótico
Authors: Heck Miriam Ferrazza , Kaiber Carmen Teresa
Published: May 2020

Apresenta-se, neste artigo, uma análise em referenciais curriculares no que se refere aos conhecimentos geométricos a serem desenvolvidos nos anos finais do Ensino Fundamental. É parte integrante de uma pesquisa que está em andamento que tem como objetivo investigar possibilidades da constituição de um currículo para a Geometria nos anos finais do Ensino Fundamental, na região de abrangência da 36ª Coordenadoria Regional de Educação (CRE) do Estado do Rio Grande do Sul, tomando como referência os constructos do Enfoque Ontossemiótico do Conhecimento e da Instrução Matemática (EOS). A análise toma como suporte elementos da Análise Textual Discursiva e como referência a Idoneidade Epistêmica do EOS. Inicialmente se destaca a análise epistêmica produzida no documento que apresenta a Base Nacional Comum Curricular- BNCC, no que se refere aos conhecimentos geométricos e, em seguida, a análise realizada no documento que apresenta a proposta curricular de um município pertencente a 36ª CRE, tomando como referência a BNCC. Resultados apontam a presença, na BNCC, de modo equitativo, dos componentes epistêmicos situações-problemas, linguagem, regras, argumentos e relações. Na Proposta Curricular analisada foi possível perceber o encaminhamento de um trabalho com a Geometria focada em situações envolvendo grandezas e medidas, com pouca ênfase em situações envolvendo os objetos geométricos e suas propriedades. Ademais, a BNCC aponta para um trabalho com a geometria das transformações, além de aspectos formais de estudo dos objetos geométricos, que não estão presentes na Proposta Curricular. Destaca-se que o documento analisado se encontra em processo de reestruturação.
Percepção dos alunos de ciências contábeis sobre a estrutura conceitual básica da contabilidade
Authors: Schlup Daiani , Soschinski Caroline Keidann , Klann Roberto Carlos
Published: May 2020

Objetivou-se analisar o entendimento dos alunos do curso de ciências contábeis sobre o conceito e a utilidade da estrutura conceitual no ensino de contabilidade. Para o levantamento de dados, foi utilizado um questionário estruturado, aplicado presencialmente no período de maio e junho de 2017, em acadêmicos do cursos de ciências contábeis de duas universidades de Santa Catarina, uma de caráter público e outra comunitária. Os dados dos 134 respondentes foram analisados considerando a diferença entre as universidades, gênero, experiência profissional e também o fato do respondente ter cursado, ou não, a disciplina de Teoria da Contabilidade. Os resultados apontam que a qualidade da informação contábil é o aspecto da estrutura conceitual que os acadêmicos têm menor domínio, sendo que os alunos da universidade pública tem mais dificuldade no assunto relativo ao valor justo, enquanto os da universidade comunitária apresentam maior dificuldade em relação ao objetivo da contabilidade. Como contribuições, aponta-se que diante das maiores dificuldades dos alunos, as universidades e professores podem modificar seus planos de ensino, procurando enfatizar tais temas. Também demonstra-se que os conceitos aprendidos no decorrer da disciplina são em parte “perdidos” na sequência, o que pode indicar a necessidade de alterações na didática utilizada pelos professores.

Published: May 2020

Este estudo tem por objetivo analisar o processo de institucionalização da auditoria interna em uma universidade federal, na perspectiva de auditores e gestores. O estudo é desenvolvido à luz da Teoria Institucional, com apoio do modelo de análise proposto por Tolbert e Zucker (1998). No que diz respeito aos aspectos metodológicos, a pesquisa é de natureza qualitativa e assume a forma de estudo de caso único. Para coletar os dados, foram realizadas entrevistas com auditores e gestores da alta administração e análise de documental. Os resultados indicam baixa aderência ao estágio de habitualização e moderada aos estágios de objetificação e sedimentação do processo de institucionalização. Verifica-se que a auditoria interna em estudo: conta com boa estrutura física; mantém os procedimentos organizados; acompanhou o processo de modernização da atividade e que há apoio e reconhecimento por parte da alta gestão. Por outro lado, os resultados indicam que há necessidade de esclarecer as finalidades e a forma de atuação do setor na Universidade, de incrementar o processo de acompanhamento das recomendações emitidas e de ampliar o acesso a programas e sistemas de informação.

Authors: Soares Sandro Vieira , Lima Filho Raimundo Nonato , Casa Nova Silvia Pereira de Castro
Published: May 2020

Este artigo tem por objetivo identificar se o Google Acadêmico é uma opção para análise de citações dos artigos publicados nos periódicos brasileiros de contabilidade. Para isto, foram coletadas as citações de 1.810 artigos publicados entre 2007 e 2012 por quinze revistas brasileiras de contabilidade; a coleta foi feita via Google Scholar nos meses de abril anos de 2014, 2015 e 2016. O percentual de artigos não encontrados pelo Google Acadêmico apresentou uma tendência de queda ao longo do período: de 2,8% em abril de 2014 para 0,9% em abril de 2016. A frequência de artigos cuja contagem de citações caiu entre 2014 e 2016 foi de 1,6% da amostra. O coeficiente de correlação de postos de Spearman entre o Fator de Impacto de 5 anos do Spell e a média de citações dos artigos publicados entre 2008 e 2012 por revista é de rs = 0,918, embora o Google Acadêmico tenha recuperado um número de citações de 3 a 9 vezes maior por revista do que o Spell. A contribuição deste artigo permite que os pesquisadores e instituições conheçam as limitações e possibilidades do uso do Google Acadêmico nas pesquisas de análise de citações de artigos brasileiros e na análise do impacto das pesquisas.

Published: May 2020

O cenário do ambiente organizacional das Instituições de Ensino Superior privadas (IESP) no Brasil vêm se alterando com a formação de grandes grupos educacionais, por meio de fusões e incorporações e do desenho de um novo contexto da educação superior, diante de um ambiente de alta competição, pautado pela busca de vantagens competitivas e pela diferenciação. Nesse contexto, o objetivo dessa pesquisa foi o de analisar as competências utilizadas pelos coordenadores de curso para responderem às novas demandas estratégicas em uma IES privada que sofreu um processo de aquisição, passando a fazer parte de um grande grupo econômico da área educacional. Quanto à metodologia, trata-se de uma investigação qualitativa, exploratória, de amostra não-probabilística. Os resultados indicaram que o papel dos coordenadores de cursos vem sofrendo mudanças, sendo que alguns desses profissionais que já possuem experiência em gestão, adaptam-se mais facilmente; enquanto outros, sem experiência gerencial, através do sensemaking atribuem novo sentido às tarefas para serem capazes de desempenhar as funções. Concluiu-se que o cenário de alta competitividade das IESP tem impactado na atuação dos coordenadores, diminuindo a sua atuação acadêmica e o uso de competências para o gerenciamento do curso como uma unidade de negócios.
Rebuilding the Ba'thist State: Party, Tribe, and Administrative Control in Authoritarian Iraq, 1991–1996
Authors: Blaydes Lisa
Published: May 2020

How do authoritarian states establish control in the wake of regime threatening shocks? The 1991 Uprisings—anti-regime protests across Iraqi provinces—were a turning point for Saddam Hussein and the Ba'th Party. I discuss two strategies deployed by the Ba'thist regime to
reconsolidate political authority after the rebellion, both influenced by concerns about extending control to geographically-challenging locations. First, the regime collaborated with tribal intermediaries to outsource monitoring and social control of rural areas, particularly in border regions.
Second, the regime expanded Ba'th Party influence in Iraq's "second cities," like Basra and Mosul, major population centers located near the border of rival states Iran and Turkey. These findings suggest weak states seek to increase their strength through investment in local political actors
and in ways that are geographically differentiated across regions.

Abstract. Despite the numerous studies investigating haze formation mechanism in China, it is still puzzling that intensive haze episodes could form within hours directly following relatively clean periods. Haze has been suggested to be initiated by the variation of meteorological parameters and then to be substantially enhanced by aerosol-radiation-boundary layer feedback. However, knowledge on the detailed chemical processes and the driving factors for extensive aerosol mass accumulation during the feedback is still scarce. Here, the dependency of the aerosol number size distribution, mass concentration and chemical composition on the daytime mixing layer height (MLH) in urban Beijing is investigated. The size distribution and chemical composition-resolved dry aerosol light extinction is also explored. The results indicate that the aerosol mass concentration and fraction of nitrate increased dramatically when the MLH decreased from high to low conditions, corresponding to relatively clean and polluted conditions, respectively. Particles having their dry diameters in the size of ~ 400–700 nm, and especially particle-phase ammonium nitrate and liquid water, contributed greatly to visibility degradation during the winter haze periods. The dependency of aerosol composition on the MLH revealed that ammonium nitrate and aerosol water content increased the most during low MLH conditions, which may have further triggered enhanced formation of sulphate and organic aerosol via heterogeneous reactions. As a result, more sulphate, nitrate and water soluble organics were formed, leading to an enhanced water uptake ability and increased light extinction by the aerosols. The results of this study contribute towards a more detailed understanding of the aerosol-chemistry-radiation-boundary layer feedback that is likely to be responsible for explosive aerosol mass growth events in urban Beijing.

Abstract. Iceland is a highly active source of natural dust. Icelandic dust has the potential to affect directly the climate via dust-radiation interaction, and indirectly via dust-cloud interaction, snow/ice albedo effect and impacts on biogeochemical cycles. The impacts of Icelandic dust depend on its mineralogical and chemical composition. However, lack of data has prevented an accurate assessment of the role of Icelandic dust in the Earth system. Here, we collected surface sediment samples from five major Icelandic dust hotspots. Dust aerosols were generated and suspended in atmospheric chambers, and PM10 and PM20 fractions were collected for further analysis. We found that the dust samples primarily consist of amorphous basaltic material ranging from 8 wt% (from the Hagavatn hotspot) to 60–90 wt% (other hotspots). Samples had relatively high total Fe content (10–13 wt%). Sequential extraction of Fe to determine its chemical form shows that dithionite Fe (Fe oxides such as hematite and goethite) and ascorbate Fe (amorphous Fe) contribute respectively 1–6 %, and 0.3–1.4 % of the total Fe in Icelandic dust. The magnetite fraction is 7–15 % of total Fe and 1–2 wt% of PM10, which is orders of magnitude higher than in mineral dust from North Africa. Nevertheless, about 80–90 % of the Fe is contained in pyroxene and amorphous glass. The initial Fe solubility (ammonium acetate extraction at pH 4.7) is from 0.08–0.6 %, which is comparable to low latitude dust such as that from North Africa. The Fe solubility at low pH (i.e., 2) is significantly higher than typical low latitude dust (up to 30 % at pH 2 after 72 hrs). Our results revealed the fundamental differences in composition and mineralogy of Icelandic dust from low latitude dust. We attribute these differences to the low degree of chemical weathering, the basaltic composition of the parent sediments, and glacial processes. Icelandic dust contributes to the atmospheric deposition of soluble Fe and can impact primary productivity in the North Atlantic Ocean. The distinct chemical and mineralogical composition, particularly the high magnetite content (1–2 wt%), indicates a potentially significant impact of Icelandic dust on the radiation balance in the sub-polar and polar regions.
Model-based climatology of diurnal variability in stratospheric ozone as a data analysis tool

Published: May 2020

Abstract. Observational studies of stratospheric ozone often
involve data from multiple instruments that measure the ozone at different
times of day. There has been an increased awareness of the potential impact
of the diurnal cycle when interpreting measurements of stratospheric ozone
at altitudes in the mid- to upper stratosphere. To address this issue, we
present a climatological representation of diurnal variations in ozone with
a 30 min temporal resolution as a function of latitude, pressure and
month, based on output from the Goddard Earth Observing System (GEOS)
general circulation model coupled to the NASA Global Modeling Initiative
(GMI) chemistry package (known as the GEOS-GMI chemistry model). This
climatology can be applied to a wide range of ozone data analyses, including
data intercomparisons, data merging and the analysis of data from a single
platform in a non-sun-synchronous orbit. We evaluate the diurnal climatology
by comparing mean differences between ozone measurements made at different
local solar times to the differences predicted by the diurnal model. The
ozone diurnal cycle is a complicated function of latitude, pressure and
season, with variations of less than 5 % in the tropics and subtropics,
increasing to more than 15 % near the polar day terminator in the upper
stratosphere. These results compare well with previous modeling simulations
and are supported by similar size variations in satellite observations. We
present several example applications of the climatology in currently
relevant data studies. We also compare this diurnal climatology to the
diurnal signal from a previous iteration of the free-running GEOS Chemistry
Climate Model (GEOSCCM) and to the ensemble runs of GEOS-GMI to test the
sensitivity of the model diurnal cycle to changes in model formulation and
simulated time period.
A powerful lidar system capable of one-hour measurements of water vapour in the troposphere and the lower stratosphere as well as the temperature in the upper stratosphere and mesosphere

Published: May 2020

Abstract. A high-power Raman lidar system has been installed at the high-altitude research station Schneefernerhaus (Garmisch-Partenkirchen, Germany) at 2675 m a.s.l., at the side of an existing wide-range differential-absorption lidar (DIAL). An industrial XeCl laser was modified for linearly polarized single-line operation at an average power of about 180 W. This high power and a 1.5-m-diameter receiver allow us to extend the operating range for water-vapour sounding to 20 km within one hour, at an uncertainty level of the mixing ratio of 1 to 2 ppm. This was achieved for a vertical resolution varied between just 0.2 and 0.6 km in the stratosphere and could be improved for stronger smoothing. The lidar was successfully validated with a balloon-borne cryogenic frost-point hygrometer (CFH). In addition, temperature measurements to altitudes around 87 km were demonstrated for one hour of signal averaging. The system has been calibrated with the DIAL, the CFH and radiosondes.

Este artículo estudia la posibilidad de aplicar la teoría de grafos o redes al análisis de la progresión temática y la cohesión textual. Para ello, se analizan seis textos de divulgación científica: tres sobre el mismo tema, el aceite de palma, otro sobre el aceite de oliva y dos de control; uno creado por la unión de dos textos de temas diferentes y el otro por párrafos con distintas temáticas seleccionados aleatoriamente. Se ha creado, de cada texto, un grafo no dirigido y pesado de coocurrencias con ventana 5 gram. En primer lugar, se han analizado las medidas globales del grafo para conocer su topología; en segundo lugar, se ha empleado el grado de intermediación de los lemas para conocer los temas de cada texto y se ha estudiado como estos evolucionan; en tercer lugar, a través de la modularidad del grafo, se ha analizado en qué párrafos aparecen los diferentes temas y cómo ha evolucionado.
“Nadie le quite, pena de excomunión mayor”. Escritura expuesta y confesionalización en Córdoba del Tucumán durante la Colonia
Authors: Benito Moya Silvano G. A.
Published: May 2020

Se estudian, a través de la cultura escrita, aspectos del proceso de disciplinamiento social en Córdoba del Tucumán durante los siglos XVII y XVIII.Dentro del paradigma de la confesionalización observamos cómo la escritura sirvió al poder monárquico y eclesiástico para buscar legitimación social con la generación de dispositivos eficaces que aquí analizamos: concretamente, los edictos de la Inquisición y las tablillas de excomunión. En Córdoba, los agentes considerados en el estudio son variados, desde el gobernador y el obispo hasta curas y regidores, pasando por alcaldes y provisores en sede vacante.En la llamada “pedagogía del miedo”, la escritura fue un contundente vehículo utilizado por ambos poderes —a veces en pugna—, para disciplinar tanto a elites como a sectores populares, alfabetizados o analfabetos, para uniformar y poner conformidad religiosa a los habitantes; proceso imposible de llevar a cabo sin visibilidad y presencia en el espacio público. Es allí donde la escritura expuesta tuvo un papel central.

Published: May 2020

This study aims to identify the key points of the FELDA land inheritance issues and their possible solutions. Land (Group Settlement Areas) Act 1960 was analyzed as it is the main act that regulates FELDA land management. This study discovered that Section 14 limits the land holding to not more than two holders while Section 15 prohibits subdividing or partitioning over FELDA land holding. An administrator is appointed to manage the land on behalf of other heirs and this practice poses risk as the administrator may fail to execute the trust. Hence, inter vivos gift is proposed to address this problem. It was also found that status of FELDA land holding is considered as ‘Conditional Holding’ since it limits the number of registered holders and authorisation to inherit the FELDA land to the second FELDA settlers generation This study concluded that inter vivos gift is legal and this is evidenced from the Section 215, National Land Code 1965 which demonstrates that FELDA land holding can be transferred to the second generation via ‘Form 14A’ at the land offices with the consent from the State Authority and FELDA management as specified in the Land (Group Settlement Areas) Act 1960.

Published: May 2020

Objective: Endometrial fibrosis, the primary pathological feature of intrauterine adhesion, may lead to disruption of endometrial tissue structure, menstrual abnormalities, infertility, and recurrent pregnancy loss. At present, no ideal therapeutic strategy exists for this fibrotic disease. Eupatilin, a major pharmacologically active flavone from Artemisia, has been previously reported to act as a potent inducer of dedifferentiation of fibrotic tissue in the liver and lung. However, the effects of eupatilin on endometrial fibrosis have not yet been investigated. In this study, we present the first report on the impact of eupatilin treatment on transforming growth factor beta (TGF-β)-induced endometrial fibrosis.Methods: The efficacy of eupatilin on TGF-β–induced endometrial fibrosis was assessed by examining changes in morphology and the expression levels of fibrosis markers using immunofluorescence staining and quantitative real-time reverse-transcription polymerase chain reaction.Results: Eupatilin treatment significantly reduced the fibrotic activity of TGF-β–induced endometrial fibrosis in Ishikawa cells, which displayed more circular shapes and formed more colonies. Additionally, the effects of eupatilin on fibrotic markers including alpha-smooth muscle actin, hypoxia-inducible factor 1 alpha, collagen type I alpha 1 chain, and matrix metalloproteinase-2, were evaluated in TGF-β–induced endometrial fibrosis. The expression of these markers was highly upregulated by TGF-β pretreatment and recovered to the levels of control cells in response to eupatilin treatment.Conclusion: Our findings suggest that suppression of TGF-β–induced signaling by eupatilin might be an effective therapeutic strategy for the treatment of endometrial fibrosis.
Digestate: The Coproduct of Biofuel Production in a Circular Economy, and New Results for Cassava Peeling Residue Digestate
Authors: N. Aso Sammy
Published: May 2020

Circular economic paradigm applies residue from one process as input material for another, fostering sustainable benefits for humanity. Anaerobic digestion (AD) is an attractive technology for biogas production in a circular economy. Digestate is the residual organic matter generated as coproduct of biogas. Because digestate is nutrient rich and largely stabilized, it has varied management options. Digestate is suitable for direct use as bio-fertilizer and is a good amendment material to improve soil physical properties. However, the quality, safety, and utility of digestate are dependent upon the characteristics of feedstock, digester process, pre- and post- digestion treatments. Digestates emanating from AD of animal manure, energy crops, food processing residues, and other feedstocks have been reported in published literature. On the other hand, there is dearth of reports on digestate emanating from AD process that utilized cassava peeling residue (CPR) as sole feedstock. This chapter presents relevant information on digestates including production, feedstock, quality and safety requirements, processing and treatment technologies, regulatory aspects, applications management options, cost implications, as well as challenges and opportunities. In addition, new results of nitrogen (N), phosphorus (P), and potassium (K) compositions of liquid fraction of CPR digestate are reported.
Twist Tetrahedral-Tilting Structure Built from Photoluminescent Cadmium Chalcogenide Clusters
Authors: Wu Wen-Chia , Yang Chung-Sung , Xu Yan
Published: May 2020

The newly synthesized cadmium chalcogenide ternary cluster is composed by six [S3Se]2− tetrahedron units, coordinated with six Cd2+ cations. The potential cavity, calculated by the PLATON program, occupied 38.1% of crystal cell volume. The charge of unit cell is neutral. Therefore, the unit cell formula is determinate as [Cd6S18Se6]. Two strong solid-state luminescence peaks, centered at 450 nm and 498 nm, were observed from the ternary [Cd6S18Se6] clusters by λ = 370 nm radiation. The 450 nm peak is due to the porosity property of cadmium chalcogenide clusters. However, the 498 nm peak has not been reported for the cadmium chalcogenide clusters before. In this study, we demonstrate that the 498 nm peak is attributed to the embedded Se atoms confined in the [S3Se]2− unit of [Cd6S18Se6] cluster. The luminescent output from the ternary [Cd8S18Se6] cluster is stable in room temperature for more than 6 months.
Electromagnetic Levitation of Metal Melts
Authors: Glebovsky Vadim
Published: May 2020

The main advantage that attracted the attention of researchers was the lack of contact of liquid metal with refractory lining, which ensured the elimination of one of the main sources of metal contamination by such a harmful impurity, such as oxygen. This is especially important for melting refractory and highly reactive metals and semiconductors. Compared to other melting methods, which also ensured the absence of contact of liquid metal with the crucible (vacuum arc, electron beam floating zone, cold crucible, plasma, etc.), EML of metal melts has a number of significant advantages. Among all types of noncontact technologies, only EML has the functions of levitation and heating.

Exploring the Factors Hindering the Use of Green Architecture in Nigeria
Authors: Faisal Koko Auwalu , Bello Muhammed
Published: May 2020

The construction industry in Nigeria has continuously witnessed rapid development as a result of massive investments in infrastructural projects such as housing. The continuous growth of this industry and the conventional approach to construction practices in Nigeria have negatively affected the environment and the wellbeing of the populace. Therefore, the concept of green architecture, also known as sustainable architecture, is a new approach in Nigeria’s construction industry that strives to achieve environmental sustainability. However, various factors have hindered its adoption and utilisation. This study, therefore, examined the various factors hindering the use of green architecture through various literature reviewed and administered questionnaires to built environment professionals in Nigeria to ascertain their perception of those identified factors. Data gathered from the questionnaires were analysed using descriptive statistical tools and ranked according to each factor’s mean index score and relative importance index. The results of the study revealed the most prominent factors hindering the utilisation of green architecture in Nigeria. Hence, findings from this study suggest that more efforts such as public enlightenment and the provisions of incentives are needed to be done by the government, built environment professionals, and other stakeholders in Nigeria’s construction industry for the promotion of green architecture.

Published: May 2020

This study will briefly explain the production of 103Pd via cyclotron for brachytherapy use. The excitation functions of 103Rh(p,n)103Pd and 103Rh(d,2n)103Pd reactions were calculated using ALICE/91, ALICE/ASH, and TALYS-1.2 codes and compared with published data. Production of 103Pd was done via 103Rh(p,n)103Pd nuclear reaction. The target was bombarded with 18 MeV protons at 200 μA beam current for 15 h. After irradiation and radiochemical separation of the electroplated rhodium target, at the optimum condition, 103Pd was absorbed into Amberlite®IR-93 resin. The preparation of the brachytherapy seed, which is loaded by the resin beads, has also been presented. At least, the method to determine the dosimetric parameters for the seed by experimental measurement has been presented.

El presente trabajo tiene por objetivo demostrar cómo la inacción de las instituciones responsables de conservar la fuente han conducido a su ruina. Para ello se relata el proceso por el que la fuente de agua minero-medicinal de Troncoso, bien cultural y patrimonio minero, se ha ido degradando hasta llegar a un estado ruinoso agravado en 2019 cuando se hundió parcialmente la techumbre del edificio que la alberga. Las medidas previstas para atajar dicha degradación desde el año 2002 hasta el presente, casi nunca llevadas a la práctica, no han resuelto el problema demostrándose una ineficaz gestión cultural tanto de los propietarios como de las administraciones públicas. Determinados compromisos institucionales parecen apuntar a la rehabilitación de la fuente, pero están pendientes de ciertos trámites burocráticos que suelen ser muy lentos. Mientras tanto, los vecinos, hartos de la ineficacia de unos y otros, han decidido tomar la iniciativa por su cuenta y, en la medida de sus posibilidades, adecentar y cuidar tan emblemático bien patrimonial por su cuenta. El trabajo se ha documentado en base a estudios previos y a la consulta sistemática de los medios de comunicación que han dado noticia de los hechos.

This paper has the aim of showing how inactivity of responsible institutions for preserving the fountain have led it to collapse. For that, it describes the process by which the mineral water spring of Troncoso, a cultural and mining heritage, has deteriorated to its present dilapidated condition worsened in 2019 when the roof of the building that houses partially sank. The measures envisaged to prevent degradation since 2002 to the present, almost never put into practice, they have not solved the problem proving ineffective cultural management both owners and public administrations. Certain institutional commitments seem to point to the rehabilitation of the source but are pending certain bureaucratic procedures that can be very slow. Meanwhile, neighbours, fed up with the inefficiency of each other, have decided to take the initiative to clean up and care as emblematic heritage site on their own. This paper has considered prior studies and the notices of news media that have notified the facts.
Legado mineiro da Bacia Carbonífera do Douro: permanências de um Sistema em transformação
Authors: Alves Ribeiro Daniela
Published: May 2020

A identificação do legado mineiro da Bacia Carbonífera do Douro levanta questões face aos paradigmas de reconhecimento patrimonial e da intervenção sobre as marcas de uma actividade económica estritamente ligada ao território que transforma e que hoje nos chegam. No território transformado pelo Sistema Carbonífero do Douro (SCD) o actual enquadramento patrimonial identifica “fragmentos” que não permitem a sua leitura como integrante de um sistema sociotécnico. Como alternativa, é apresentado um entendimento de como o Sistema se vai territorializando, sedimentando uma “paisagem antropogeográfica”. De um exclusivo reconhecimento das “construções resistentes” hoje existentes, propomos a identificação do conjunto de relações temporal e espacialmente transversais que, assumindo formas distintas em função do contexto integrado, foram determinando as morfologias do SCD, imputando-lhes a dimensão identitária inerente a um sistema produtivo motor de aculturação, possibilitando ler o Sistema como tal. Face à capacidade de representação dos valores que estabelecem vínculos entre o presente e o passado sobre a qual deverá incidir a condição patrimonial, identifica-se neste conjunto de relações as regras para a transformação futura do território que o SCD moldou, procurando-se veicular um entendimento prospectivo de património, então potenciador de uma requalificação territorial integrada e dotada de significado.

The recognition of the mining legacy of Douro Coal Basin raises issues regarding the paradigms of heritage recognition and of intervention on the present marks of an economic activity strictly linked to the territory, so transformed by it. In the territory transformed by the Carboniferous System of Douro (SCD) the current heritage context identifies only “fragments”, which don’t allow their understanding as an integrated part of a sociotechnical system. As an alternative, it is proposed the understanding of how the SCD was being territorialized and settling an “anthropogeographic landscape”. This paper identifies temporal and spatial correlations that supported SCD territorialisation. These correlations assumed distinct forms according to the surrounding context and determined SCD morphologies, attributing to them the identity inherent to a productive system that enhanced acculturation and allowing its perception as a system. The evaluation of heritage condition and future interventions should consider values and needs that result from the links between present and past. Under this assumption, a group of intervention principles for the transformation of the SCD territory are identified. The goal is to move closer to a prospective understanding of heritage, enabling an integrated and meaningful territory requalification.
Buenas prácticas aplicadas en la actividad extractiva de lignito: restauracions respetuosas con el medio ambiente que modifican el paisaje minero del Val de Ariño (Teruel)
Authors: Pizarro Losilla Antonio
Published: May 2020

La explotación de lignito en la provincia de Teruel ha sido una actividad industrial de primera magnitud y generadora de riqueza durante un periodo importante de nuestra historia más reciente. Así en la denominada Cuenca Oliete Norte o también conocida como Cuenca Andorra-Alloza-Ariño, se encuentra el Val de Ariño, enun territorio donde confluyen un conjunto de características del subsuelo y de la corteza terrestre, que definen una geología de unos terrenos especiales que configuran un yacimiento de lignito de grandes proporciones. Hoy observamos un paisaje antrópico, modificado por la actividad humana, que ha sido modelado, estructurado, recuperado, restaurado, donde hubo una actividad extractiva frenética. Un paisajeplagado de minas, tanto de interior como a cielo abierto, de aquí que el carbón ha grabado su impronta en el paisaje. Restos de minas y las restauraciones realizadas, dibujan escenografías y vertientes policromas donde no falta ningún color. En el Plan Nacional de Patrimonio Industrial de 2011, en su anexo V, se recoge un catálogomínimo, en el que se relacionan una serie de elementos o lugares a preservar, seleccionados por TICCIH-España. Entre ellos figura: “Las minas de carbón y el paisaje minero del Val de Ariño”, de manera que este lugar se contempla como un conjunto patrimonial excepcional, de vital importancia para el futuro de la zona.

The exploitation of lignite in the province of Teruel, has been an industrial activity of first magnitude and generator of wealth during an important period of our recent history. Thus,the so called Cuenca Oliete Norte, also known as Cuenca Andorra-Alloza-Ariño, is home to the Val de Ariño, a territory where the special characteristics of the subsoil and the terrestrial crust define a geology of special terrains that form a deposit of lignite of great proportions. Today we observe an anthropic landscape, modified by the human activity, that has been modeled, structured, recovered, restored, where a frenzied extraction took place, plagued by subterranean and open-airmining activity. From here the coal has engraved its imprint on the landscape, as well as remains of the mines and the restorations carried out, drawings and polychromatic slopes. In the catalogue of elements or sites to be preserved selected by TICCIH-Spain, contained in the Annex V of the 2011 National Industrial Heritage Plan, the next reference is found: "The coal mines and themining landscape of the Val de Ariño". That is a proof that the place is already considered to be of exceptional heritage value and of vital importance for the future of the area.
Neofidia Strother, a new name for Fidia Baly, 1863 and redescription of Fidia kanaraensis (Jacoby, 1895) with a new host record and notes on natural history (Coleoptera, Chrysomelidae, Eumolpinae)

Neofidia Strother nom. nov., is proposed as the replacement name for Fidia Baly, 1863, a junior homonym of Fidia Motschulsky, 1861 (not 1860, Griffin 1936). A list of the included species of Neofidia Strother nom. nov. and Fidia Motschulsky, 1861 is provided for clarity. Fidia medvedevi nom. nov. is the new replacement name proposed for Lypesthes vietnamicus Medvedev, 2015. Fidia kanaraensis (Jacoby, 1895) is redescribed and habitus, male and female genitalia are figured. Cashew (Anacardium occidentale L.) is reported as a new host of F. kanaraensis and partial information on the life history is provided. Eggs are laid singly on the surface of soil, and are covered with excreta and soil. Larvae tunnel into the tender roots. Adults are nocturnal and feed on tender leaves.

Background: Association between endocan and nontraditional anthropometric indices, as distinct cardiovascular disease risk factors, has not been examined in previous studies. Endocan is a novel inflammation biomarker with its higher levels involved in cardiometabolic diseases development. Taking into consideration that obesity is an independent risk factor for many cardiometabolic diseases, we aimed to explore the relationship between endocan levels and novel anthropometric indices i.e., body adiposity index (BAI), cardiometabolic index (CMI), a body shape index, body roundness index, conicity index, lipid accumulation product index and visceral adiposity index and traditional ones i.e., waist circumference, hip circumference, body mass index, waist-to-height ratio and waist-to-hip ratio in adult population. Methods: A total of 177 participants were included. Anthropometric indices and biochemical parametres were measured. Results: Univariate regression analysis demonstrated positive correlations of endocan and almost all anthropometric data. To explore independent associations of endocan and anthropometric parameters, the Model which fulfilled criteria for ordinal regression testing was created. Adjusted odds for BAI given in the Model (OR=1.120, 95% CI 1.036-1.212, P=0.004), demonstrated that a rise in BAI by 1 unit increased the probability of higher endocan concentration by 12%. As well, a rise in CMI for 1 unit, increased the probability for higher endocan levels for 2.6 times (OR=2.599, 95% CI 1.006-6.712, P=0.049). A total of 20.1% of variation in endocan levels could be explained by this Model. Conclusions: Non-traditional obesity indices, BAI and CMI independently correlated with higher serum endocan levels in adult population.
Dedicaciones de exámenes en escuelas primarias y colegios de la Ciudad de México y Veracruz (1824-1868)
Authors: Martínez Carmona Pablo
Published: May 2020

The dedication of examinations to religious, patriotic, heroic and civil characters and images was part of the ceremonial educational world in nineteenth-century Mexico. These school practices were related to a transmission of feelings of devotion to hierarchies and paternalism. This article reviews the meaning of these dedications in fundamental aspects, such as schooling, citizenship and national identity. The article is structured in two sections that refer, on the one hand, to the use of these dedications in elementary education and, on the other hand, in the higher education given in colleges and institutes. The analysis is based on Mijail Bajtin´s discourse genres and the concept of construction of Maurice Agulhon's idealizations; the notions of paternalism, construction of the hero and the formation of political loyalties are also used. The time frame covers from the emergence of First Federal Republic in 1824 until the dawn of the Restored Republic in1868. The focus of the study is Mexico City, the capital of the country, which  had the greatest concentration of educational establishments. For the purpose of regional comparison, the cases of two cities in the eastern state of Veracruz,  Xalapa, the capital, and Veracruz, the republic's main port, are also reviewed.
A invisibilidade da imigração galega e a produção de uma identidade social hibrida nas novas terras (São Paulo, 1880-1910)
Authors: Biccas Maurilane De Souza , Vidal Diana Gonçalves
Published: May 2020

The article explores the characteristics of Galician emigration to Brazil between the late 19th and early 20th centuries, focusing on the São Paulo region. It is organized into two complementary parts. In the first one, it deals with the historiography on the subject, inquiring statistics and trying to examine the profile of the Galician migrant who seeks the ocean crossing. In the same section, it discusses what we consider the double invisibility of Galician immigration, mixed with the Portuguese from the northern Portugal or with the generality of Spanish immigration in the official records of entry into the country. In the second section, the Centro Español de Santos and the school created by it are the subject of analysis in order to understand how the Galician immigrants produced a hybrid social identity from an associative practice. In the Final Comments, some questions are asked about the denomination of the entity.
