Auto-filtering validation in citizen science biodiversity monitoring: a case study
Authors: Lotfian Maryam , Ingensand Jens , Ertz Olivier , Oulevay Simon , Chassin Thibaud
Published: July 2019

Abstract. Data quality is the primary concern for researchers working on citizen science projects. The collected data by citizen science participants are heterogeneous and therefore must be validated. There are several validation approaches depending on the theme and objective of the citizen science project, but the most common approach is the expert review. While expert validation is essential in citizen science projects, considering it as the only validation approach can be very difficult and complicated for the experts. In addition, volunteers can get demotivated to contribute if they do not receive any feedback regarding their submissions. This project aims at introducing an automatic filtering mechanism for a biodiversity citizen science project. The goals of this project are to first use an available historical database of the local species to filter out the unusual ones, and second to use machine learning and image recognition techniques to verify if the observation image corresponds with the right species type. The submissions that does not successfully pass the automatic filtering will be flagged as unusual and goes through expert review. The objective is on the one hand to simplify validation task by the experts, and on the other hand to increase participants’ motivation by giving them real-time feedback on their submissions. Finally, the flagged observations will be classified as valid, valid but uncommon, and invalid, and the observation outliers (rare species) can be identified for each specific region.
Research and implementation of big data visualization based on WebGIS

Published: July 2019

Abstract. With the development of geographic information technology, the way to get geographical information is constantly, and the data of space-time is exploding, and more and more scholars have started to develop a field of data processing and space and time analysis. In this, the traditional data visualization technology is high in popularity and simple and easy to understand, through simple pie chart and histogram, which can reveal and analyze the characteristics of the data itself, but still cannot combine with the map better to display the hidden time and space information to exert its application value. How to fully explore the spatiotemporal information contained in massive data and accurately explore the spatial distribution and variation rules of geographical things and phenomena is a key research problem at present. Based on this, this paper designed and constructed a universal thematic data visual analysis system that supports the full functions of data warehousing, data management, data analysis and data visualization. In this paper, Weifang city is taken as the research area, starting from the aspects of rainfall interpolation analysis and population comprehensive analysis of Weifang, etc., the author realizes the fast and efficient display under the big data set, and fully displays the characteristics of spatial and temporal data through the visualization effect of thematic data. At the same time, Cassandra distributed database is adopted in this research, which can also store, manage and analyze big data. To a certain extent, it reduces the pressure of front-end map drawing, and has good query analysis efficiency and fast processing ability.
Initiative aiming to introduce children to maps in Kenya
Authors: Njore Catherine M. , Kimari Charles Mwangi , Thiong’o Kuria
Published: July 2019

Abstract. The age at which one is introduced to cartography and map making skills has been identified as a major factor in creating interest and awareness in mapping, more so when incorporated in the education system. Additionally, participation of children in various cartographic arts and maps competitions develops their cognitive knowledge and skills. Despite this information, Kenya continues to lag behind in the incorporation of qualified cartographic products into the education curriculum. The objective of this project therefore was to sensitize the various education stakeholders in the country on the need to develop childrens’ cognitive skills and abilities at an early stage in their life. The project, which is at its initial stage, formulated under a book club called “ThinkWords” mainly targets primary school children (4–10 years) and is currently working with one of the schools based in Nyeri County, Kenya as a pilot project. The children are engaged in various activities which include maps and their uses. Currently the “ThinkWords” club has a membership of 50, which is inclusive of children and their teachers. The ultimate goal of the project is to convince the relevant education stakeholders in the country on the importance of introducing cartography in schools, by sharing the children’s work with the relevant government authorities and stakeholders on need of children themed maps in terms of symbology. The project is then envisioned to be rolled out to other parts of the country and eventually lead to the inclusion of cartographic training skills into the education system.
City maps: Dreams, Art, Cartography, Planning
Authors: Palagiano Cosimo
Published: July 2019

Abstract. The importance of cities becomes ever greater not only for the modification of the landscape, but also for the distribution of social classes. Poets, philosophers and artists have imagined ideal cities that could satisfy the need for a good quality of life for citizens. Since the most ancient civilizations poets and philosophers have imagined ideal cities, with road plots corresponding to the various social classes. In the final text I will describe some examples of ideal cities presented by Homer, especially in the description of the shield of Achilles, from Plato in the description of his Atlantis, etc. Atlantis (Ἀτλαντὶς νῆσος, "island of Atlas") is a fictional island mentioned in Plato's works Timaeus and Critias, where Plato represents the ideal state imagined in The Republic. The city depicted in the Homeric shield of Achilles, as an ideal form, centred and circular, competes with the other city scheme based on an orthogonal plan and linear structures. The form of the Homeric city has exerted a paradigmatic function for other cities in Greece and Rome. Among the best known images of ideal cities I will consider the Città del Sole (City of the Sun) by Tommaso Campanella and Utopia by Thomas More. There are many books of collection of paintings of cities (G Braun and F Hogenberg, 1966).The most complete and interesting is that of Caspar van Wittel or Gaspar van Wittel (1652 or 1653, Amersfoort – September 13, 1736, Rome). He was a Dutch painter who played a remarkable role in the development of the veduta. He is credited with turning city topography into a painterly specialism in Italian art (G Briganti, 1996). A rich collection of maps of Rome in the books by Amato Pietro Frutaz. The city "liquid dimension" represents the complexities and contradictions of civic communities increasingly characterized by fragmentation and social unease.
Modern Archeological Mapping: Towards Immersive VR Use in Archeology
Authors: Pettitt Alisa , Fuhrmann Sven
Published: July 2019

Abstract. Detailed mapping is essential to systematic archeological practice and is conducted in five stages: identification, evaluation and excavation, site preservation and documentation, analysis and interpretation, and education. As archeological mapping evolves the five stages remain the same, enhanced by the integration of new geoinformation technologies to better record archeological information. Even with technological advances essential spatial data and mapping products are often overlooked when archeological information reaches the education stage. This disconnect occurs when artefacts are exhibited without considering communicating spatial context, i.e. presented behind glass cabinets. This is a critical concern as understanding spatial context is essential to grasping heritage site histories. As a solution to this wide-reaching issue in geovisualization and the digital humanities, this research proposes a framework for developing immersive virtual reality heritage site applications that preserve the spatial context of archeological mapping. Applying the framework, this research produced the heritage site application “VR Riverbend”, which successfully relinks archeological materials with essential spatial context. Thus, VR Riverbend connects archeological data with place, remedying issues of artefact/context disconnect inherent in traditional exhibits. Developing immersive VR heritage site applications following the introduced framework provides a solution towards effective spatial and often multi-layered archeological heritage site education.
Lógicas de funcionamento do Tinder. Uma análise da aplicação e das perceções dos utilizadores.
Authors: Sepúlveda Rita , Vieira Jorge
Published: July 2019

O número de aplicações de mobile dating tem vindo a aumentar, mas o Tinder goza de um reconhecimento por parte dos utilizadores e de uma visibilidade mediática e estudo científico que o distingue das demais. Porém, ainda não é claro como os diferentes agentes em jogo interagem, nem como as informações dos utilizadores são tratadas e combinadas através da ação dos algoritmos. Na procura de elucidar esses aspetos, este artigo explora como o design, arquitetura e affordances da plataforma estruturam as ações dos utilizadores e, consequentemente, moldam a utilização, questionando de seguida, como as informações e utilização geram determinados resultados através da ação do algoritmo. Para tal, recorreu-se a uma metodologia qualitativa, combinando duas técnicas de recolha de dados o que permitiu, por um lado, uma análise crítica através da identificação das diferentes possibilidades de funcionamento do Tinder e de como é imposto um fluxo de utilização e, por outro, através dos discursos dos utilizadores, compreender como estes interpretam as affordances da aplicação no decorrer da sua utilização.

Como principais resultados, verificou-se que parte dos utilizadores não pareciam estar conscientes da presença e ação do algoritmo. Indicaram também que as suas ações estavam condicionadas em diversos momentos da utilização, porém contornavam (alguns) (d)esses condicionantes encontrando novas formas de uso.

Symptom Burden in Long-Term Survivors of Head and Neck Cancer: Patient-Reported
Versus Clinical Data
Authors: Pocobelli Gaia , Ziebell Rebecca , Fujii Monica , Hutcheson Katherine A. , Chang Steven , McClure Jennifer B. , Chubak Jessica
Published: July 2019

Introduction: The symptom burden faced by long-term head and neck cancer survivors
is not well understood. In addition, the accuracy of clinical data sources for symptom
ascertainment is not clear.Objective: To 1) describe the prevalence of symptoms in
5-year survivors of head and neck cancer, and 2) to evaluate agreement between symptoms
obtained via self-report and symptoms obtained from clinical data sources.Methods: We
recruited 5-year survivors of head and neck cancer enrolled at Kaiser Permanente
Washington (n = 54). Symptoms were assessed using the MD Anderson Symptom Inventory head
and neck cancer module. For each symptom, we assessed the agreement of the patient’s
survey response (“gold standard”) with the 1) medical chart and 2) administrative health
care claims data. We computed the sensitivity, specificity, positive predictive value
(PPV), and negative predictive value, along with their 95 percent confidence intervals,
for each clinical data source.Results: Eighty percent of patients responded. Nearly all
participants (95 percent) reported experiencing at least one symptom from the MDASI-HN,
and 93 percent reported two or more symptoms. Among patients reporting a given symptom,
there was generally no evidence of the symptom from either clinical data source (i.e.,
sensitivity was generally no greater than 40 percent). The specificity and PPV of the
clinical data sources were generally higher than the sensitivity.Conclusion: Relying
only on medical chart review and/or administrative health data would substantially
underestimate symptom burden in long-term head and neck cancer survivors.
Classifiers, partitions, and measurements: Exploring the syntax and semantics of sortal classifiers
Authors: Bale Alan , Coon Jessica , Arcos Nicholás
Published: July 2019

In many languages, measure terms like item and kilo, as in two items of furniture and two kilos of rice, can be used either to partition the nominal denotation into countable units, or to measure a denotation without inducing a partition. These two types of measurements are associated with two different syntactic structures: a partition-structure where the measure term forms a constituent with the noun independent of the numeral, and a measure-structure where the measure term forms a constituent with the numeral. Some researchers have claimed that in classifier languages, sortal classifiers are (most often) used in a partition-structure—hence the classifier forms a constituent with the noun independent of the numeral. In contrast, non-sortal classifiers (i.e., measure classifiers) are often used in a measure-structure—the classifier forms a constituent with the numeral and this constituent modifies the noun. Contrary to these claims, we demonstrate that in Ch’ol (Mayan) all classifiers, sortal and non-sortal alike, are used in a measure-structure independent of the types of readings that are available with respect to the measure term. As a result, the correlation between partitioned meanings and partition-structures is not universal. We review several diagnostics that support this claim. These diagnostics can be used as a template to test the constituency structure in other classifier languages.
The LaRonde Penna Au-Rich Volcanogenic Massive Sulfide Deposit
Authors: Mercier-Langevin Patrick , Dubé Benoît , Blanchet François , Pitre David , Laberge Annie
Published: July 2019

The 2698 Ma LaRonde Penna deposit, with over 71 Mt of ore at 3.9 g/t Au (280 t Au or ~9 Moz Au), is the second largest Au-rich volcanogenic massive sulfide (VMS) deposit in the world. It is part of the Doyon-Bousquet-LaRonde mining camp in the eastern part of the Blake River Group.

The deposits of the Doyon-Bousquet-LaRonde mining camp are hosted by the volcanic rocks of the Hébé-court (base) and Bousquet (top) formations that form a southward-younging homoclinal sequence, with nearly vertical dips due to a north-south compressional event responsible for the development of an E-W–trending, steeply S-dipping, penetrative schistosity under prograde, upper greenschist to lower amphibolite facies meta-morphism. The E-trending, steeply S-dipping schistosity is associated with strong flattening, transposition, and minor folding of the volcanic rocks, alteration zones, and sulfide lenses.

The ore lenses at LaRonde Penna, which are stacked in the upper half of the Bousquet Formation, are characterized by semimassive to massive sulfides or narrow intervals of transposed sulfide veins and veinlets. The synvolcanic hydrothermal alteration at LaRonde Penna now corresponds to mappable upper greenschist-lower amphibolites-grade metamorphic assemblages.

In the upper part of the deposit, the 20 North lens comprises a transposed pyrite-chalcopyrite (Au-Cu) stockwork (20N Au zone) overlain by a pyrite-sphalerite-galena-chalcopyrite-pyrrhotite (Zn-Ag-Pb) massive sulfide lens (20N Zn zone). The 20 North lens (20N Au and 20N Zn zones) is underlain by a large, semiconformable alteration zone that comprises a proximal quartz-Mn-garnet-biotite-muscovite alteration assemblage. The 20N Zn zone tapers with depth in the deposit and gives way to the 20N Au zone. At depth in the deposit, the 20N Au zone consists of semimassive sulfides (Au-rich pyrite and chalcopyrite) enclosed by a large aluminous alteration assemblage interpreted to be the metamorphic equivalent of an advanced argillic alteration zone.

At LaRonde Penna, the presence of sulfide lenses characterized by Au-rich portions and base metal-rich portions demonstrates that a VMS system can generate mineralization styles that gradually evolve, both in space and time, from neutral (Au-Cu-Zn-Ag-Pb ore), to transitional, to acidic (advanced argillic alteration and Au ± Cu-rich ore) in response to the evolving local geologic setting.
Ants Correctly Locate the Zero in a Continuous Series of Numbers
Authors: Cammaerts Marie-Claire , Cammaerts Roger
Published: July 2019

Knowing that the workers of the ant Myrmica sabuleti have a concrete notion of zero, and that they can expect the time and the place of the next delivery of food, we experimentally examined if these ants could locate the zero at its due cardinal place. The ants were visually trained step by step to a continuous decreasing series of two amounts of elements differing by one unit, and of which, at each step, either the lower or the higher amount was associated with food. The ants were tested at each step of the decreasing series, and each time essentially reacted to the amount of elements which would be associated with the following food delivery. This showed that the ants could distinguish amounts of elements as being lesser or higher by one element, up to and including the absence of element (the zero). At the end of the series, the ants perceived the zero as being ‘1 element less 1’ as well as 1 element as being ‘0 element plus 1’. They thus correctly located the zero at its due cardinal place.
El papel de las mujeres en los rituales religiosos y las performances políticas entre los nahuas en la época precortesiana y colonial
Authors: Szoblik Katarzyna
Published: July 2019

El presente trabajo parte de los estudios más amplios acerca del lugar de la mujer en la oralidad nahua y se enfoca en uno de los aspectos concretos de este tema, es decir, en la variedad de papeles desempeñados por los personajes femeninos en la manifestación artística inscrita en los contextos religiosos y políticos. El análisis de los papeles de la mujer en los cantos-bailes (en nahuatl: cuicatl) registrados en varios manuscritos coloniales y en los mitos indígenas lleva a las conclusiones importantes acerca de la conceptualización idealizada de lo femenino en la cultura estudiada.

La reelaboración del mito como apropiación de la memoria andina en Baladas peruanas de González Prada
Authors: Huarcaya Gutierrez Evelyn Isamar
Published: July 2019

En este artículo, se tiene como hipótesis que a partir de la implementación  del elemento del mito dentro de la composición de las piezas poéticas de Baladas peruanas, se produce una apropiación de la memoria andina. Es decir, a través de las estrategias de textualización como la dedicatoria, la cita pórtico y el epígrafe, Prada legitima en Baladas peruanas una forma mítica de pensar el mundo y lo inserta dentro de un contexto de mayor  raigambre como el europeo-occidental. Para lo cual se establecen primero vasos comunicantes entre Comentarios reales del Inca Garcilaso de la Vega y propiamente Baladas peruanas, a partir del cual  se rescata el elemento del mito, se  le reutiliza y recrea de una manera plástica,  nueva y autónoma, conservando la matriz de los mitos prehispánicos. De esta manera, el sujeto textual se apropia de elementos de la cultura andina y su forma de ver el mundo a nivel estructural y semántico lo que deviene en una autentificación e universalización de una manera válida y diferente de concebir la historia
Las transfiguraciones reveladoras: metamorfosis clásicas y mitos prehispánicos en la literatura peruana
Authors: Usandizaga Lleonart Helena
Published: July 2019

Se estudia la coexistencia y el diálogo entre la mitología andina y la mitología clásica en tres autores peruanos del siglo XX: Gamaliel Churata, Edgardo Rivera Martínez y Laura Riesco. En los tres, se activa el significado de las transformaciones míticas en su dimensión material, que desvela la sacralidad y belleza de la materia sin oponerla a lo divino y sublime. En Churata, las transformaciones andinas y clásicas muestran la importancia de la naturaleza y la animalidad en la construcción de lo humano, y por otro lado el enunciador discute la visión dicotómica de Platón respecto a materia y espíritu. En Rivera Martínez, la confluencia de lo andino y lo clásico conduce a una percepción compleja de la belleza y la armonía, mientras que en Riesco permite entender la formación de una conciencia que incluye a lo otro y lo propio en un espacio creativo, germen de la escritura.
Desangrar. Violencia y relaciones inter-étnicas en algunos relatos de la Amazonía peruana
Authors: Pau Stefano
Published: July 2019

La región amazónica peruana es el escenario en el que vive y actúa una terrorífica figura que se conoce como sacacara, pelacara o sacaojos. Este personaje “mítico”, percibido por los habitantes de la región como una realidad simbólica alternativa, tiene algunas características propias de su manera de obrar que lo conectan con el tigre negro o yanapuma, protagonista de otros cuentos de la tradición oral, cuya difusión se hizo más frecuente a partir de la época del llamado “boom” del caucho. En el artículo, a partir de algunos relatos orales y de algunas referencias de literatura escrita, se abordará el tema de la explotación y de las desequilibradas relaciones de poder entre poblaciones autóctonas y occidentales, sintetizadas en el paralelismo entre la extracción de la savia de los árboles de goma y la práctica del desangramiento, extraño modus occidendidel tigre negro.
Nuevas formas de hibridación de imaginarios míticos en la literatura contemporánea mexicana
Authors: Remón-Raillard Margarita
Published: July 2019

La interrelación entre mito, Historia y producción cultural constituye un engranaje sumamente complejo. Los especialistas han recurrido a metáforas de movimiento para describirlo. Se realizará un análisis diacrónico de un corpus de textos pertenecientes a la literatura mexicana contemporánea: Elena Garro, Carlos Fuentes, José Emilio Pacheco (segunda mitad del siglo XX); Yuri Herrera y Alberto Chimal (siglo XXI). Se estudiará la permanencia o las variaciones de ciertos arquetipos míticos así como las modalidades de reescritura de cosmogonías, siempre desde una óptica que privilegia el hibridismo que se produce entre los mitos prehispánicos y clásicos.
La mexicanidad de Xólotl/Axolotl: Maravilla de la literatura y la gastronomía.
Authors: Holguin Fdo. Valerio
Published: July 2019

Para los aztecas, los axólotls eran animales divinos, ya que representaban al dios Xólotl, quien escapó convirtiéndose en maíz, maguey y, luego, en axolotl, para evitar el sacrificio, pero, finalmente, fue atrapado y sacrificado. Varios escritores mexicanos han recuperado tanto a Xólotl como a Axolotl en sus textos literarios y ensayísticos. Salvador Elizondo escribe “Ambystoma trigrinum”, texto que forma parte del libro El grafógrafo. Así también Juan José Arreola publica “El ajolote”, que después sería incluido en su Bestiario. Octavio Paz recupera el sustrato mitológico del dios Xólotl en Salamandra, así como también lo hace José Emilio Pacheco en El reposo del fuego. Mi propósito en este ensayo consiste en analizar cómo el dios azteca Xólotl y su representación anfibia Axólotl han sido objeto de estudio en la imaginación científica, cultural y literaria en el México contemporáneo.
“La mujer en fragmentos”: una lectura de un mito pipil
Authors: Jossa Emanuela
Published: July 2019

La mitología de los Pipiles, una de las civilizaciones precolombinas mesoamericanas, no es muy conocida. No hay códices prehispánicos ni crónicas de la época colonial que recojan sus mitos. En 1930 Schultze-Jena recopiló los mitos en la lengua pipil y en años recientes Rafael Lara Martínez no solamente los tradujo al castellano, sino también investigó la cosmovisión pipil. De esta forma, hay un corpus de mitos que, a través de este estudio, yo quisiera contribuir a que se conozca. Después de una breve introducción, orientada a ubicar geográfica e históricamente a los Pipiles, se analiza la relación entre el dispositivo cultural hegemónico y la cultura indígena. Luego se ofrece una lectura del mito “la mujer en fragmentos”, subrayando su especificidad en el ámbito de las culturas mesoamericanas y mostrando, escuetamente, su continuidad, más que su reescritura, en una novela contemporánea de la escritora salvadoreña Claudia Hernández.

Microhistoria del relato policial. Modulaciones políticas del detective latinoamericano
Authors: Garí Barceló Bernat
Published: July 2019

La figura del detective literario adopta distintas formas y declinaciones políticas a lo largo de su historia. La narrativa policial decimonónica ―o relato enigma― se inscribe en una matriz biopolítica y es el producto madurado de una reflexión teórica y social sobre las nuevas dinámicas del hombre moderno en el contexto de la gran ciudad. Su variante brutalizada ―el hard-boiled bosquejado por Hammet y Chandler y las distintas reformulaciones que suscita― da cuenta de un patrón reformista, agotados los presupuestos del marxismo ortodoxo y la posibilidad de una ruptura total. Finalmente, en el contexto de la posmodernidad, el metapolicial despliega una línea experimental y despolitizada. Trataré de exponerlo sumariamente en las líneas que siguen a través de algunos ejemplos seleccionados aleatoriamente.

Soil degradation is characterized by a decline in quality and decrease in ecosystems goods and it is unfavorable phenomenon. Soil is a non-renewable resource and its vulnerability to degradation depends on complex interactions between processes, factors and causes occurring at spatial and temporal scales. Both natural and antropogenic factors and processes are listed as possible causes of soil degradation. Erosion, depletion of the soil organic carbon, loss of soil fertility and biodiversity as well as acidification are particularly fast and noticeable among the major soil degradation processes.
Rozhodovanie podľa zásad spravodlivosti v prípadoch dotknutých korupciou v medzinárodnej obchodnej arbitráži

Published: July 2019

Rozhodovanie podľa zásad spravodlivosti v medzinárodnej obchodnej arbitráži sa stáva pomerne častým javom. Striktnosť národných pravidiel neumožňuje stranám flexibilitu v sporoch, ktorú vzhľadom na dlhotrvajúce obchodné vzťahy potrebujú. To, že sa v rozhodcovskom konaní neaplikujú národné právne predpisy neznamená, že by rozhodcovia nemali v rukách nástroje, ktoré môžu použiť v prípadoch, keď odhalia korupčné konanie strán priamo súvisiace s predmetným sporom. Rozhodcovia síce nemôžu prekročiť svoje právomoci, ale stále majú povinnosť skúmať a aplikovať verejný poriadok. Týmto sa musia riadiť aj v prípadoch, keď rozhodujú podľa zásad spravodlivosti.
Experimental Approaches to Alleviating Gender Dysphoria in Children
Authors: Hruz Paul W. ,   The National Catholic Bioethics Center
Published: July 2019

Clinical guidelines now recommend hormonal and surgical interven­tions together with social affirmation for children who experience a gender identity that is discordant with their biological sex. However, fundamental questions regarding the safety, efficacy, and ethics of these approaches remain unanswered. There is an urgent need for high-quality research to establish the overall risks and benefits of the current treatment paradigm. While acknowledging the complexity of the problem, competing interests, and logistical challenges, ethical imperatives and acceptable boundaries for scientific investigation can be set by considering the ultimate good of both the individual person and society as a whole. Within established guidelines for human experimentation, alternative approaches to treatment of gender dysphoria in children can be explored without compromising the dignity and bodily integrity of affected individuals.
Filosofia, Pedagogia e Teatro – relatos e experimentos em territórios da educação
Authors: Da Silva Diego José , Cilento Angela Zamora Guimarães
Published: July 2019

Nosso relato de experiência partiu da curiosidade de entendermos as questões "como ensinar?" e "o que pode ser ensinado em filosofia”? Após algumas experiências e estudos sistemáticos assumimos posições teóricas acerca da perspectiva educacional, bem como sua avaliação. Tais experiências estão indissoluvelmente relacionadas ao PIBID: uma nova visão sobre o ensinar que se atualiza a todo instante. Isso nos permitiu tratar de noções cognitivas, emocionais e físicas que interferiram diretamente no corpo do sujeito/aluno, provocando gradualmente mudança qualitativa nos corpos e no ambiente da sala de aula com a prática teatral. Objetivamos aqui apresentar e reforçar a importância dessa prática na sala de aula, pois percebemos que todo esse movimento nos ofereceu perspectivas excitantes: além do ensino rigoroso dos conceitos, contemplou-se a plasticidade no ensino de filosofia; mais do que a apreensão cognitiva e conceitual, o aluno descobriu em si mesmo potencialidades até então latentes.
O ensino de Filosofia em tempos hipermodernos: Desafios do amanhã.
Authors: Alves Mauricio Silva
Published: July 2019

A sociedade hipermoderna  tem suas estruturas fundadas na lógica do imediatismo, hedonismo, consumismo bem como no fascínio estético que torna uma sociedade alicerçada no espetáculo, este não dá subsídios que permitam o homem distinguir o que é real do que é irreal, deste modo, constitui-se um indivíduo que se imagina eterno e que não precisa cultivar a atitude  perguntante diante dos aparatos inovadores e sedutores da hipermodernidade, é por assim dizer uma traição, pois fascinado pelo imediatismo, e por todos os padrões espetaculares, porém superficiais que lhe são oferecidos, é incapaz de lidar com seus problemas existenciais. A filosofia deve permanecer à margem para garantir o seu espaço como disciplina? A proposta desse trabalho é que se busque a interdisciplinaridade que se coloca como possibilidade de efetivar uma nova maneira de ensinar a Filosofia por meio da reconsideração do discurso das disciplinas do currículo e do modo como elas se articulam sobre uma mesma temática. Nesse sentido, desenvolver um Ensino de Filosofia eficaz, nesses tempos hipermodernos, pressupõe não só a utilização dos textos clássicos dos filósofos de maneira a construir uma exegese filosófica no ensino médio, mas como um distintivo que possibilite o desenvolvimento da criticidade dos alunos do Ensino Médio por meio da interdisciplinaridade.
O DESENHO DE MODA E A EDUCAÇÃO PELO SENSÍVEL: ANÁLISE DE UMA PRÁTICA PEDAGÓGICA
Authors:   Universidade do Estado de Santa Catarina (Udesc), Rosa Lucas da , Babinski Júnior Valdecir , Silveira Icléia
Published: July 2019

O presente artigo constitui-se como análise de uma prática pedagógica aplicada na unidade curricular “Ilustração de Moda”, disciplina do quarto módulo do Curso Técnico subsequente em Produção e Design de Moda, do Instituto Federal de Santa Catarina (IFSC), Campus Jaraguá do Sul – Centro. Relata-se a prática realizada a partir de etapas subdivididas nas seguintes ações e atividades: (1) Refletir; (1.1) Coletar; (1.2) Categorizar; (1.3) Caracterizar; e (2) Desmistificar. Para tanto, pela metodologia empregada, este artigo apresenta-se como aplicado, descritivo, qualitativo e de campo. Quanto aos procedimentos técnicos envolvidos, entende-se o como bibliográfico e como pesquisa participativa. A análise da experiência relatada utiliza os fundamentos teóricos abordados por Head (1958), Duarte-Júnior (1981), Pineau (2000), Pillotto (2007) e Alexandroff (2010), quanto à educação pelo sensível, por meio de seis categorias: (i) “Experiência humana”; (ii) “Imagem da memória”; (iii) “Lógica e racionalidade”; (iv) “Comunicação sensível”; (v) “Ato criador”; e (vi) “Percepção”. Infere-se que a prática pedagógica relatada teve assertividade quanto à sensibilização dos estudantes da turma para com o desenho de moda, mas manteve-se em grande parte do tempo no campo da racionalidade e da lógica. Ainda que estas não sejam negadas na educação pelo sensível, a entrada de sensações foi limitada pelo uso de sentidos específicos: visão e audição.
Diagnóstico da qualidade da água de açudes utilizados na dessedentação animal do Vale do Taquari/RS

Published: July 2019

A água de boa qualidade é essencial para o desenvolvimento e sobrevivência dos seres vivos. No meio rural a principal forma de abastecimento ocorre por poços próprios e nascentes. A água destinada ao consumo humano deve atender ao padrão de potabilidade estipulado pela legislação, e quando destinada à dessedentação animal deve atender aos requisitos de qualidade estabelecidos em lei. O estudo objetivou avaliar as características físico-químicas e microbiológicas da água de açude destinada ao consumo animal de propriedades rurais com produção leiteira da região na região do Vale do Taquari, Rio Grande do Sul, Brasil. Do total de 104 propriedades rurais, foram coletadas amostras de 19 açudes em diversos municípios do Vale do Taquari, destinados ao abastecimento de gado leiteiro. Foram coletadas e analisadas amostras de água por meio de parâmetros físico-químicos e microbiológicos com o uso do Kit de Potabilidade Alfakit® e equipamento de rápida leitura. Os parâmetros cloreto e ferro enquadram-se nos valores permitidos pela legislação e os demais, como oxigênio dissolvido, pH, turbidez, cor, sólidos dissolvidos totais e coliformes termotolerantes estão em desacordo. Conclui-se assim que, quase todas as amostras de água analisadas (n=14) não estão de acordo com os valores estipulados pela legislação consultada. Desse modo, há a necessidade de melhor manejo e monitoramento dos açudes, bem como a elaboração e execução de um programa de educação ambiental, para capacitar e conscientizar os produtores rurais

Working memory performance is thought to depend on both striatal dopamine 2/3 receptors (D2/3Rs) and task-induced functional organisation in key cortical brain networks. Here, we combine functional magnetic resonance imaging and D2/3R positron emission tomography in 51 healthy volunteers, to investigate the relationship between working memory performance, task-induced default mode network (DMN) functional connectivity changes, and striatal D2/3R availability. Increasing working memory load was associated with reduced DMN functional connectivity, which was itself associated with poorer task performance. Crucially, the magnitude of the DMN connectivity reduction correlated with striatal D2/3R availability, particularly in the caudate, and this relationship mediated the relationship between striatal D2/3R availability and task performance. These results inform our understanding of natural variation in working memory performance, and have implications for understanding age-related cognitive decline and cognitive impairments in neuropsychiatric disorders where dopamine signalling is altered.

The bacterial Sec translocon is a multi-protein complex responsible for translocating diverse proteins across the plasma membrane. For post-translational protein translocation, the Sec-channel – SecYEG – associates with the motor protein SecA to mediate the ATP-dependent transport of pre-proteins across the membrane. Previously, a diffusional-based Brownian ratchet mechanism for protein secretion has been proposed; the structural dynamics required to facilitate this mechanism remain unknown. Here, we employ hydrogen-deuterium exchange mass spectrometry (HDX-MS) to reveal striking nucleotide-dependent conformational changes in the Sec protein-channel from Escherichia coli. In addition to the ATP-dependent opening of SecY, reported previously, we observe a counteracting, and ATP-dependent, constriction of SecA around the pre-protein. ATP binding causes SecY to open and SecA to close; while, ADP produced by hydrolysis, has the opposite effect. This alternating behaviour could help impose the directionality of the Brownian ratchet for protein transport through the Sec machinery.

Background

Forage production in the saline-sodic soil of the western Songnen Plain Northeast China depends on irrigation. Therefore, the water use efficiency (WUE) and soil chemical properties are key factors in the overall forage productivity in this water scarce region. Improving forage yield, WUE, and soil properties under irrigation are very important for food and ecological security in this water-deficient region. Additionally, a suitable irrigation schedule for this region is necessary.

Methods

A field experiment was conducted between 2015 and 2018 to evaluate the effects of irrigation on artificial grassland productivity and the changes in soil chemical properties as well as to plan a reliable irrigation schedule for the western Songnen Plain. Eight irrigation treatments were designed, which depended on the three growth stages of alfalfa. The shoot height (SH), the chlorophyll content (SPAD), the dry yield (DM), the ratio of stem to leaves (SLR), the WUE, the changes in the chemical properties of the soil, and precipitation and evaporation were investigated.

Results

The SH, DM, WUE, and SLR were significantly increased by irrigation (P< 0.01). However, the SPAD resulting from irrigation was not significantly higher than the SPAD of CK (no irrigation) (P< 0.05). In addition, the soil chemical properties at the depth of 0–100 cm were significantly decreased by irrigationP(0.05). For example, the soil electrical conductivity, sodium absorption ratio, and total alkalization were reduced 182–345 μS cm−1, 8.95–9.00 (mmolc/L)1/2, and 3.29–4.65 mmolcL−1by different irrigation treatments, respectively. Finally, considering the highest WUE of I5 (irrigation at branch stage) (2.50 kg m−3), relative high DM of I5 (787.00 g m−2), the precipitation, the evaporation, the water resources, and the changes of the soil’s chemical properties, 236.50 mm of irrigation water was recommended at the branching stage of alfalfa for the western Songnen Plain, Northeast China.

Agricultural intensification has resulted in severe soil nutrient depletion in Africa.  Alternative agricultural practices have been promoted to restore and sustain soil fertility. Use of mineral fertilizer alongside different cropping systems has been particularly promising. This study was conducted in the Guinea savannah zone of Ghana during the 2015 and 2016 cropping season (July to November) to assess the performance of soybean and maize in a rotation system. In season one, using randomized complete block design the treatments were, soybean (without treatment), inoculated soybean, soybean with phosphorus application, inoculated soybean with phosphorus application and maize. During the second season, the first season experimental plots served as main-plots and divided into four sub-plots on which maize planted and treated with four nitrogen rates in a split plot design. The results show that soybean production leads to significant increase in residual soil nitrogen content of about 16kg/ha to 55kg/ha, which is about 28 folds higher than that observed in maize fields. The level of Residual N was enhanced with inoculation. Phosphorus application during the first season of maize cultivation led to increases in residual P levels, which had a positive impact on yield of soybean in the second season. Grain yield of maize that followed soybean in a rotation system performed better than maize that followed maize at various fertilizer rates. This shows that, the residual N and P helps maize and soybean respectively in a rotation system which makes it highly economical.

The efficiency of isolates from entomopathogenic fungus Beauveria bassiana, Lecanicillium muscarium and Metarhizium rileyi in the control of eggs and third-instar nymphs of whitefly, Bemisia tabaci biotype B, was evaluated by pathogenicity and virulence tests, under laboratory conditions. For the pathogenicity tests, five leaflets of bean (Phaseolus vulgaris) plants containing 20 nymphs or 20 eggs of B. tabaci biotype B were used. The leaflets were immersed in suspension containing a concentration of 108 conidia/ml of each fungus isolate. Nymph mortality and egg viability were evaluated after seven days. The isolates that caused nymph mortality and egg viability above 80% were submitted to virulence tests, in order to estimate the lethal concentration (LC50) of each isolate. All isolates were pathogenic to eggs and third-instar nymphs of B. tabaci Biotype B. JAB07 of B. bassiana and LCMAP3790 of L. muscarium isolates presented the best results, with nymphs mortality of 96.68 ± 2.25% and 97.74 ± 1.56%, respectively. Additionally, JAB07 was the most virulent isolate, both for eggs and third-instar nymphs, with LC50 estimated of 0.012 and 0.006 × 103 conidia/ml, respectively. We suggest, future field trials are required in order to analyze the real efficiency of this isolate in the control of eggs and nymphs of B. tabaci biotype B in field conditions.
An Analysis of Human Survival Strategies in Difficult Environments: A Case Study of the Kom Highlands in Cameroon

Published: July 2019

Mountainous regions and other difficult terrains, the world over, present significant challenges to communities as they strive to carry out their daily activities. In spite of these difficulties, strategies have been employed by communities to cope with such difficulties, yielding diverse outcomes. The extent and outcomes of survival strategies employed by communities, still beg for scientific and policy edification, in the context of the Western Highlands of Cameroon. This paper contributes to bridge the knowledge gap, by examining the survival strategies employed by locals in the Kom Highlands to confront the challenges presented by the harsh physical environment. 10 key informant interviews were conducted accompanied by a representative survey of 60 farming household heads, drawn from 5 villages in Fundong. The data were analyzed using both descriptive and inferential statistical tools, including the Chi-square analysis. The results reveal that Kom displays a plethora of harsh physical environmental characteristics, prominent among them are the hilly and difficult terrain, the poor soil quality and the generally cold weather conditions witnessed here. Faced with these challenges, the population employed a number of survival strategies in the agricultural sector, housing and transport. These strategies are unfortunately inadequate and such inadequacy is accounted for by their low level of technology, poverty, ignorance and other cultural factors, among others. The study therefore recommends the need to improve and modernize agriculture through the provision of fertilizers at subsidized rates to the farming population, the encouragement of effective slope stabilization and terracing and also for rigorous government intervention in terms of road and fly over constructions.
Regulation of the ER‐bound transcription factor Luman/CREB3 in HEK293 cells

Published: July 2019

CREB3 is a transcription factor localized to the ER. Here, we investigated endogenous CREB3 expression in HEK293 cells using pharmacological and genome editing approaches. Full‐length CREB3 detected under resting conditions disappeared following treatment with tunicamycin, brefeldin A and nigericin. Treatment with cycloheximide and MG132 indicated that endogenous CREB3 is a proteasome substrate. Using cells deficient for the ER‐associated protein degradation (ERAD) factors SEL1L and Herp, we demonstrate that SEL1L, but not Herp, plays a crucial role in the posttranslational regulation of full‐length CREB3 expression. In addition, kifunensine, an α‐mannosidase inhibitor, remarkably increased full‐length CREB3 expression. Our study suggests that endogenous full‐length CREB3 is a novel substrate for ERAD and identifies unique cellular signals distinct from those in canonical ER stress.

We report the case of a patient suffering from cortical blindness following bilateral occipital stroke, who recovered normal vision in his right visual field following injection of the local anesthetic mepivacaïne. The effect was transient but reproducible, allowing the patient to lead a normal life. Effect duration increased after adjunction of paroxetine. We provide anatomical and functional brain imaging correlates of this improvement, showing particularly how functional connectivity is restored between intact perilesional cortex and distant brain regions. This serendipitous finding may potentially benefit patients suffering from visual but also nonvisual handicap following brain lesions.
Design of 2‐hydroxyethyl methacrylate‐functional macromonomer dispersants by semi‐batch cobalt chain transfer polymerization
Authors: Van Steenberge Paul H. M. , Hutchinson Robin A.
Published: July 2019

Acrylic resins for automotive coatings are produced in nonaqueous dispersions (NAD) of nanometer size. These must be sterically stabilized by oligomeric dispersants, which are complex reactive oligomers possessing vinyl and hydroxyl functionalities, controlling the size of the nanocolloid. Hence, we have developed a kinetic Monte Carlo (kMC) model to improve the molecular structure of 2‐hydroxyethyl methacrylate‐functionalized poly (butyl methacrylate) (pBMA) dispersants of ca. 6,000 g/mol produced via semi‐batch cobalt chain transfer polymerization (CCTP). The kMC‐predicted degree of functionalization is benchmarked against a novel analytic expression suitable for oligomers. Stepwise adjustment of the semi‐batch feed program illustrates the successive improvement in molecular structure of the dispersant product, finally arriving at a functionalization degree close to the theoretical maximum for CCTP.
