Classifying Skarns and Quantifying Metasomatism at the Antamina Deposit, Peru: Insights from Whole-Rock Geochemistry
Authors: Mrozek Stephanie A. , Chang Zhaoshan , Spandler Carl , Windle Steve , Raraz Cesar , Paz Alberto
Published: December 2019

At the Antamina deposit, Peru, accurate classification of exoskarns and endoskarns can be problematic when textures are mottled. In this study, we use whole-rock geochemical compositions (62 elements) of 221 samples to differentiate texturally similar endoskarns and exoskarns by comparing their compositions to least altered precursors (wall rocks and intrusive rocks). We present a simple method for discriminating these skarn types using immobile element bivariate plots. The most effective discriminators partition endoskarn and exoskarn into distinct domains defined by the composition of each precursor; these include Al2O3 versus heavy rare earth elements and some high field strength elements. Using these geochemical parameters, undifferentiated skarn samples can be more reliably classified as endoskarn or exoskarn. The effectiveness of these element pairs is attributed to their significantly different initial concentrations in wall rocks versus igneous precursors and their immobility during skarn formation. While immobile elements can differentiate the skarns, mobile element gains and losses (quantified using isocon analysis) provide insight on the bulk mineralogical and mass changes that take place during skarn formation.

Published: December 2019

This study evaluated the relationship between IPSAS adoption and financial reporting quality in South West, Nigeria. Specifically, it analysed the effect of IPSAS adoption on credibility and comparability of financial statements. Additionally; salient factors influencing IPSAS implementation were investigated. Primary data collected from one hundred and eighty accountants in South West Nigeria were analysed using tabulation, graphs, factor analysis, and Goodman and Kruskal’s gamma statistics.The empirical results indicated that IPSAS adoption exerted significant and positive relationships with financial reporting quality, credibility and comparability of financial statements. Decisively, discoveries from this study reflect that implementation cost, staff training, technological factor, IPSAS knowledge and awareness and availability of expertise significantly affect IPSAS implementation. However, findings further revealed that IPSAS implementation is not significantly influenced by institutional commitment, cultural, sociological, legal, political and environmental factors. Based on these findings, the authors recommend that considerable amount of money should be set aside for full adoption and implementation of IPSAS in Nigeria.
Trade Policy, Infrastructure and Agricultural Output in Nigeria
Authors: Effiom Lionel , Ebi Bassey
Published: December 2019

The collapse of the international price of crude oil in 2015 and its attendant negative consequences on government fiscal capacity and development efforts re-echoed the need for Nigerians to return to agriculture as the surest means of conserving foreign exchange and revamping productive capacity. Within this context, this paper deploys the autoregressive distributed lag (ARDL) econometric methodology to investigate the impact of Nigeria’s trade policy and infrastructural development on agricultural value added. Findings show that in the long run Nigeria’s trade liberalization policy is a disincentive to the growth of the agricultural sector value added, while key components of infrastructure (roads, telecommunications, and electricity consumption) had a significant relationship with the agricultural sector. We advocate guided trade liberalization wherein, while embracing the principles of conventional trade deregulation, the government properly articulates the weakness of the economy’s productive structure and encourage farmers and local producers to attain maturity. Specifically, the current ban on some selected food items should be consolidated, without which Nigeria would continue to be a net food importer. Goveronment might consider studying and implementing the African Development Bank’s Infrastructure Action Plan for Nigeria.
The Influence of Guttural Consonants /χ/, /ħ/, and /h/ on Vowel /a/ in Saudi Arabic
Authors: Alsager Haroon N.
Published: December 2019

This paper presents a comparative study which investigates the influence of Saudi Arabic guttural consonants /χ/, /ħ/ and /h/ on the vowel /a/ when they are adjacent and in the same syllable. Cohn (2007, 2009), Flemming (2001), and Keating (1996) discuss a unified model in which phonology and phonetics are treated as two distinct elements of one domain where each element has an effect on the other to some degree. McCarthy (1991, 1994), Rose (1996), Zawaydeh (1999, 2004), and BinMuqbil (2006) presented phonological studies on gutturals, as well as discussions on gutturals as a natural class, which uphold the phonological aspect of Cohn’s (2009) unified model. The aim of this study is to address the phonetic aspect of Cohn’s (2009) unified model by analyzing the phonetic effects of guttural-vowel coarticulation. An acoustic analysis method was used as a framework for this investigation to extract first formant frequency (F1) and second formant frequency (F2) to measure the influence in the coarticulation. For the purpose of this study, seven native Saudi Arabic speakers were recorded pronouncing 70 Saudi Arabic words. The results showed that guttural consonants have an influence on the vowel /a/ by lowering and backing it when they are adjacent and in the same syllable, while the vowel /a/ in the nonguttural consonants is raising and fronting their adjacent vowel /a/ in the same syllable in comparison with the vowel /a/ in the guttural environment.
An Ethnographic Study of Linguistic Landscapes at China-and-Vietnam Border
Authors: Li Jia , Yan Ying , Hou Fuhuan , Dong Juan
Published: December 2019

Along with China’s Belt and Road Initiative, China is engaging itself with its neighboring countries and many border cities have been strategically positioned as trading nodes linking China to the outside world. This is particularly true with Hekou, a minority-centered border town between China and Vietnam where local minority languages, Chinese, Vietnamese and English are displayed at various spaces. Adopting a critical sociolinguistic ethnography (Heller, 2006; Li, 2017), this study focuses on the intersection of language practices and ideologies by examining the language use and language choices displayed both in public and private signs. Data were collected through linguistic signs displayed at Hekou and individual interviews with local people. Findings indicate that Chinese as China’s official language enjoys the most visibility, and English, though considered as a lingua franca, only acquires symbolic value rather than being used for daily communication at the border town. In contrast, Vietnamese, as a newly emerged foreign language, is acquiring cultural and economic capitals for the local people’ educational and employment opportunities. As a minority-centered border town, the visibility of minority languages on cultural events stands both for tourism boom and for border integrity. The study provides a new context for understanding multilingual practices and China’s border language planning and management in the context of China’s cooperation with Southeast Asian countries.
Humor as Monotony Breaker in Funny Ads: A Multi-Modal Discourse Analysis of Ads of Pakistani Ufone & Jazz Cellular Companies

Published: December 2019

The present study explores and analyzes the role of humor in the advertisement as the message in advertisements keeps a pivotal value constructing and promoting the idea of promotional activity by any company. So, the companies and promoters of products utilize and employ various distinctive and discursive strategies to promote their products focusing on the interests of their consumers. The research concludes that Pakistan is the one amongst other countries, in which, advertisers and promotors utilize humor as an important feature in advertainments at a huge level. Along with entertainment, the promoters promote the text and its discourse through humor which influences the decision-buying process of consumers. However, they often try to utilize humor neutralizing the social or personal values. Recent studies prove that intelligent and sensible use of humor by the companies can lead them to success if it is more relevant to the products’ nature and function. A Multi-Modal Approach, employing Fairclough’s (1989) 3D model along with Kress and van Leeuwen’s (1996) grammar of visual design, is employed to analyze data. The findings of the study suggest that the humor if handled properly, can play a vital role in captivating consumers’ interest towards the product as it takes them away from the tensions of life and makes the product more appealing. Moreover, humor as a monotony breaker makes the ad more attractive that ultimately adds to the promotion of the product.
Enhancing Intrinsic Motivation to Learn in Adults: Empowering ESL Students
Authors: Hassan Hamid , Hariri Nisrin A. , Khan Khushnoor
Published: December 2019

The apex in the acquisition of a second language is dependent upon motivation and attitude coupled and nurtured in a formal language learning milieu. Adult learners of English as a Second Language (ESL) can be motivated intrinsically in numerous ways. The types of motivation, whether intrinsic or extrinsic, are not categorically different; instead, they lie in the same transition of self-determination. Direction relative to one’s surroundings serves as a long-range goal and sustains students’ motivation to learn a second language. The decision to learn in many cases comes from within. Internalizing the reasons for language learning are internalized, students feel more insistency, comfort, and ease. Teachers should strive to promote positive self-talk and guided self-evaluation within students, along with emphasizing mastery of specific goals. Setting higher but attainable goals for an ESL learner activates endeavors and influences performance. Instructors should reveal intrinsic attractions latent in every subject as the appeal-laden lessons have a high quality to attract most students. Knowing and assimilating a target language’s culture contributes positively to a learner’s development. An ESL classroom should be a welcoming, positive place where communication needs are met and where language anxiety is minimum, and the student seems to enjoy many of the practice opportunities. Instructors should create a stimulating, supportive ambiance that fosters self-esteem and interest in learning. Repeated readings in small groups develop expertise in verbal skills. Further, it encourages curiosity, which is of paramount significance for creating motivation and making ESL learning fun. Present research will be a harbinger of further research in Middle Eastern educational milieu and will open new vistas for academicians and practitioners involved in teaching as a foreign language.

Objective: to evaluate the effect of the implementation of an instrument based on diagnostic standardized language systems, interventions and results on the quality ofnurses' records. Methods: a quasi-experimental study that compared the quality of nurses' records through the Quality of Diagnosis, Interventions and Outcomes in medical records of patients hospitalized in cardiovascular units before and after the implementation of astandardized instrument. Results: there was a significant improvement in the quality of records after the use of the instrument in the "diagnosis as a process" (p=0.018), "diagnosis as a product" (p=0.019) and "Nursing outcomes" (p<0.001) dimensions. The "Nursingintervention" dimension showed no statistically significant difference, but obtained an increase in the score at post-intervention time. Despite the improvement in the qualityof the records, the mean of the total score remained low after implementation of the instrument (14.8±5.7 vs. 29.0±10.5; p=0.003). Conclusion: the use of an instrument based on diagnosis standardized language systems, interventions and results has improved the quality of nurses' records in cardiovascular units and should be considered an important tool for improving the documentation on patient records.

Esta recuperación material puede ser interpretada como la culminación de un proceso iniciado a finales del siglo XVIII, sustentado por la ideología romántica y la reivindicación del medievalismo. Gracias al análisis de los libros de viajes, como nuevo género literario, y los testimonios de los periodistas románticos comprendemos la génesis de la recuperación y puesta en valor de un indudable monumento histórico-artístico.AbstractAfter many years of abandonment and in a state of ruin, the castle of Guadamur (Toledo) was restored between 1887 and 1900 by Carlos Morenés and Tord, IV Baron de Cuatro Torres, VI Count of Asalto, under the supervision of Jerónimo López de Ayala. This material recovery can be interpreted as the culmination of a process that begun in the late eighteenth century and that was supported by the romantic ideology and the medieval revival. Thanks to the analysis of travel books, as a new literary genre, and testimonies of romantic journalists, we understand the genesis of the recovery and enhancement of an undoubted historical-artistic monument.
La recuperación de dos repuestos de pólvora del siglo XVIII en Melilla: análisis y restauración = Recovery of two Spare Gunpowder Warehouses from the XVIIIth Century in Melilla: Analysis and Restoration
Authors: Ramírez González Sergio , Bravo Nieto Antonio , Bellver Garrido Juan Antonio
Published: December 2019

Los repuestos de pólvora construidos en las fortificaciones de la Edad Moderna pertenecen a una tipología arquitectónica escasamente estudiada. Como derivación de los polvorines en su reducida dimensión, tales repuestos cumplían la función de almacenaje de municiones para una batería o zona concreta del recinto, facilitando su rápido y cómodo abastecimiento. A través del presente trabajo abordaremos el análisis de varios de ellos como parte integrante de la estructura fortificada de Melilla, en el caso del almacén de Florentina y los repuestos de la Batería Real y del fuerte de Victoria Grande, estos dos últimos realizados por el ingeniero Juan Martín Zermeño en el primer tercio del siglo XVIII. Su restauración, hace escasos años, puso de manifiesto la necesidad del trabajo de historiadores y arqueólogos para poder interpretarlos en sus distintas variables. Con ello, se consiguió una correcta recuperación de los espacios al sacar a la luz sus principales elementos.      AbstractThe spare gunpowder warehouses built in the fortresses of the Modern Age belong to an architectural layout scarcely studied. As for the reduced dimensions of the tinderboxes, such gunpowder warehouses fulfilled the function of ammunition depot for a battery, or specific area in the enclosure, thus facilitating its quick and convenient supply. Throughout the present work we will address the analysis of some of them as integral part of the fortified structure of Melilla, as is the case in Florentina‘s warehouse, and the spare gunpowder warehouse in the Royal Battery, as well as Victoria Grande‘s fortress, the last two work undertaken by the engineer Juan Martín Zermeño in the first third of the 18th century. Its recent restoration revealed the need for historians and archaeologists in order to interpret them in their various variables. By doing so, it was achieved the right spaces recovery shedding light on their main elements.
Ojos curiosos y capital: sobre el turismo visual decimonónico = Curious Eyes and Capital: About Nineteenth-Century Visual Tourism
Authors: Fernández Polanco Aurora
Published: December 2019

Tomaré la bubble vision («visión burbuja») –el paradigma acuñado por Hito Steyerl con el que alude a la globalización neoliberal– como punto de partida para trazar (desde «el hoy») una incursión en la construcción estética del ojo moderno y su pulsión escópica: paseante, viajero, burgués ocioso y, sobre todo, curioso. Un paseo por la inmersión, la curiosidad y la pulsión escópica del turismo visual decimonónico dictado por el capital. Intentaré mostrar cómo ese mundo de divertimento que florecía alrededor de los aparatos de visión suponía, ya entonces, algo más que simples cambios tecnológicos en las formas de entretenimiento de masas. Lo entenderé como una forma de adiestramiento para aprender a vivir en la lógica del capital.AbstractFrom the bubble vision –the paradigm proposed by Hito Steyerl to make reference to  neoliberal globalization– as started point I would trace (from «today») an incursion in the aesthetic construction of the modern eye and its scopic drive: walker, traveler, idle bourgeois; and, above all, curious. A walk by the immersion, curiosity and the scopic drive of nineteenth-century visual tourism promoted by capital. I aim to show how the world of entertainment that flourished around the viewing devices meant, already then, much more than just technological changes in the forms of mass entertainment. I will suggest that it was a form of training how to live in the logic of capital.

La dimensión espacial del «ser usuario de museo»: reflexiones sobre la construcción social de un espacio expositivo inclusivo = The Space Dimension of «Being A Museum User»: Reflections on the Social Construction of an Inclusive Exhibition Space
Authors: Mouratidis Ioannis
Published: December 2019

Partiendo de algunas perspectivas teóricas sobre la construcción social del espacio y teniendo presentes los estudios que vinculan el arte actual y ese nuevo concepto espacial, este artículo investiga las posibles articulaciones entre espacio social, arte y forma de exposición de ese arte. Con la ayuda de dos propuestas artísticas de la última edición de documenta, se reflexiona acerca de la construcción social del espacio expositivo. Documenta 14 se entiende como el resultado de unos cambios políticos y sociales más generalizados. Su propuesta expositiva sigue una tendencia que viene consolidándose los últimos años. En el presente artículo sirve como ejemplo de creación de un nuevo espacio relacional, ampliado hacia lo temporal y lo social, como medio de representación de una sociedad inclusiva en un entorno social adverso.AbstractBased on some theoretical perspectives on the social construction of space and bearing in mind the studies that link current art and this new spatial concept, this article investigates the possible articulations between social space, art and ways of exhibition of that art. With the help of two artistic proposals from the latest edition of documenta, we reflect on the social construction of the exhibition space. Documenta 14 is understood as the result of more generalized political and social changes. Its expository proposal follows a trend that has been consolidated in recent years. In this article serves as an example of creating a new relational space extended to temporal and social dimensions, as a way of representing an inclusive society in an adverse social environment.
El arte del Egipto predinástico. Ritual, significado y función = Predynastic Art in Egypt. Ritual, Sense and Function
Authors: Pérez Largacha Antonio
Published: December 2019

El arte del período predinástico se ha estudiado y entendido como característico de unas culturas neolíticas que precedieron a la unificación de Egipto y el comienzo de la I dinastía. Sin embargo, las investigaciones y excavaciones realizadas en los últimos años revelan que el arte faraónico tuvo algunos de sus precedentes en este período.En este artículo analizaremos la evolución del arte y su intencionalidad a lo largo de dicho período, al tiempo que estudiaremos las manifestaciones artísticas desde la óptica de la antropología cultural para entender el arte del Egipto predinástico en su contexto cultural y social, en especial en el ámbito de los rituales y en el proceso de creación de una memoria cultural.AbstractThe art of the Predynastic period has been studied and understood as a cultural manifestation of the Neolithic cultures preceeding to the unification of Egypt and the beginning of the 1st dynasty. However, the investigations and excavations carried out in recent years have showed that Pharaonic art had some of its origin in this period.In this article we will analyse the evolution of art and its intentionality throughout this period, while we will be studying the artistic manifestations from the perspective of cultural anthropology, looking for new ways of asking a work of art to understand it in its cultural and social context.
Due quæstiones vitruviane riconosciute: la base attica e il capitello composito nel terzo libro del De prospectiva pingendi di Piero della Francesca e un plagio conclamato di Luca Pacioli = Two Recognized Vitruvian Problems: The Attic Base and the Composite Capital in the Third Book of De Prospectiva Pingendi by Piero della Francesca and an Evident Plagiarism by Luca Pacioli
Authors: Di Teodoro Francesco P.
Published: December 2019

Il saggio prende in considerazione due problemi vitruviano-pierfrancescani rimasti sino a oggi senza spiegazione e neppure riconosciuti come tali dai moderni esegeti del De prospectiva pingendi: la lunghezza del plinto della base attica (Libro III, propositio sexta) e la dimensione della concavità dell’abaco del capitello composito (Libro III, propositio septima).In ambedue i casi i dati numerici danno conto dell’obbligata impossibilità di Piero nell’offrire soluzioni ai passi guasti dei codici vitruviani, tutti con numerosi errori. La condizione di Piero è la stessa di Leon Battista Alberti: nessuno dei due è un filologo. Lo studio rende ragione anche delle oscillazioni dimensionali proposte da Alberti per il lato del plinto.Il saggio è occasione per «smascherare» un plagio di Luca Pacioli proprio in relazione ai due temi principali dell’intervento.AbstractThe essay takes into consideration two problems related to Vitruvius and Piero della Francesca that have remained unexplained up to now and are not even recognized as such by the modern exegetes of De prospectiva pingendi: the length of the plinth of the Attic base (Book III, propositio sexta) and the size of the concavity of the abacus of the composite capital (Book III, propositio septima). In both cases the numerical data reveal Piero’s impossibility to offer solutions to faulty passages of the Vitruvian codes, all with numerous errors. Piero’s condition is the same as Leon Battista Alberti: neither is a philologist. The study also explains the dimensional oscillations proposed by Alberti for the plinth side.The essay is an opportunity to «unmask» a plagiarism by Luca Pacioli precisely in relation to the two main themes examined here.
Introduzione. La prospettiva come tema vitruviano = Introduction. Perspective as a Vitruvian Theme
Authors: Camerota Filippo
Published: December 2019

Con la diffusione della prospettiva lineare, l’architettura divenne uno dei principali temi di studio degli artisti rinascimentali. La necessità di rappresentare architetture credibili impose ai pittori di imparare a disegnare come gli architetti, combinando piante e alzati e applicando le regole proporzionali e morfologiche tramandate da Vitruvio. I trattati di prospettiva accolsero sistematicamente mirate istruzioni sul disegno degli edifici, così come i trattati di architettura dedicarono spazio alla rappresentazione prospettica, considerandola come una disciplina corrispondente a ciò che Vitruvio chiamava «scaenographia». A sancire lo stretto legame tra la prospettiva dei pittori e la scenografia vitruviana fu principalmente Daniele Barbaro che compose il suo celebre trattato di prospettiva come approfondimento del tema che tanto lo aveva impegnato nel suo altrettanto celebre commento a Vitruvio.AbstractWith the spread of linear perspective, architecture became one of the main disciplines studied by Renaissance artists. The need to represent credible architecture forced painters to learn how to draw like architects, combining plans and elevations and applying the proportional and morphological rules handed down by Vitruvius. The treatises of perspective systematically welcomed instructions on the design of buildings, just as the architectural treatises dedicated space to perspective representation, considering it as a discipline corresponding to what Vitruvius called «scaenographia». To establish the close link between the perspective of painters and the Vitruvian scenography was mainly Daniele Barbaro who composed his famous treatise on perspective as a deepening of the theme that had so busy him in his equally famous commentary on Vitruvius.
Instâncias da relação entre teatro e público: o espectador como participante do ato teatral
Authors: Desgranges Flávio
Published: December 2019

Neste artigo, o autor aborda a relação entre teatro e público a partir de duas instâncias, que podem ser pensadas em tensão produtiva. Por um lado, a importância da colaboração do público no movimento teatral, partindo da noção de que não há alteração na arte que possa ocorrer sem a efetiva participação dos espectadores. E, por outro, o necessário engajamento do público-participante para a realização do evento teatral, tendo em vista que o fato artístico não se efetiva sem o ato criativo do espectador.
Levante Artístico - diverso e disperso
Authors: Rocha Gustavo Falabella
Published: December 2019

O artigo analisa o trabalho da Zona de Arte da Periferia - ZAP 18, de Belo Horizonte em sua sede, no bairro Serrano. Com pesquisa voltada para teatro e realidade(s), a ZAP 18 leva à cena questões de interesse coletivo, como a criminalidade, a história do Brasil, o transporte público, as relações humanas e capitalistas, a paixão pelo futebol, entre outras. Para mais, com as dificuldades para manutenção de seu espaço e de seus integrantes, o grupo encontrou uma forma criativa de se manter ativo, por meio da construção do “levante artístico”, conceito edificado em torno de relações artísticas temporárias, que se dão mais em virtude do espaço do que pela relação enraizada de seus integrantes.

Para tanto, recorreu-se à literatura específica, tal como experiências de outros países latino-americanos a fim de problematizar como o teatro tem auxiliado no desenvolvimento de habilidades sociais, imprescindíveis ao convívio escolar. Em uma sociedade que cada vez mais estimula o êxito individual, o teatro na escola se mantém como um lugar de resistência, pois além de enriquecer a expressão e a comunicação, gera um sentimento de grupo e desenvolve a compreensão nas relações com o outro, enriquecendo as capacidades sociais de cada um, tão necessárias à formação integral da pessoa e à vida em sociedade.
Pela linha do trem: a pedagogia do teatro na rede pública de ensino do Rio de Janeiro
Authors: Trotta Rosyane , Morais Andreia , Rangel Luiza , Mangeth Ana
Published: December 2019

O artigo se desenvolve a partir de relatos de experiência de três professoras de artes cênicas da Rede Municipal de Ensino do Rio de Janeiro em áreas conflagradas da cidade. A prática pedagógica das autoras cria uma área comum entre a realidade social, a cultura local, a história de vida dos alunos e o olhar do artista-docente, de modo a refletir sobre a função e as possibilidades do ensino de artes nesses contextos. A pesquisa evidencia a necessidade de conexão entre o panorama histórico-geográfico, as condições de trabalho do professor e o objetivo de manter o enfoque metodológico no potencial transformador do teatro na educação básica.
Teatro, ciência e divulgação científica para uma educação sensível e plural
Authors: Lopes Thelma , Dahmouche Monica Santos
Published: December 2019

O momento em que vivemos tem sido marcado por profundos retrocessos em vários campos da atuação humana e em diferentes partes do globo, especialmente na América Latina. Em tempos nos quais direitos básicos são ignorados, as artes, erroneamente, são vistas como supérfluas e atacadas frontalmente. A despeito do cenário desfavorável, há iniciativas que se fortalecem na busca de ambientes alternativos aos espaços tradicionais de criação artística e no diálogo colaborativo entre múltiplas áreas do conhecimento. O principal objetivo deste artigo é estimular a discussão acerca do intercâmbio entre teatro, ciência e cidadania, tendo como pano de fundo as ações desenvolvidas no Museu Ciência e Vida.

Authors: Sertori Rafael Henrique Viana
Published: December 2019

A escrita desse artigo tem por objetivo apresentar algumas discussões em torno da formação e da atuação do intérprete de dança, considerando a multiplicidade de contextos artísticos e pedagógicos nos quais a dança se estrutura. Além disso, defende-se o uso do termo intérprete de dança, na tentativa de descrever e refletir sobre suas especificidades de criação e atuação nessa linguagem artística. O artigo ainda apresenta trechos de entrevistas realizadas com duas artistas-pedagogas que atuam na cidade de São Paulo, a fim de contribuir com a discussão sobre o intérprete na atualidade.
Uma revisão do teatro infantil: entre o teatro escolar e o espetáculo de arte
Authors: Gomes Sidmar Silveira
Published: December 2019

O presente artigo propõe uma revisão histórica do teatro infantil brasileiro, debruçando-se principalmente sobre a produção dramatúrgica voltada à criança na primeira metade do século XX. Tem-se como fito inventariar um marcante acontecimento referente a essa história, a saber, a ramificação da ideia de teatro infantil em duas práticas: o teatro infantil escolar, realizado por crianças em contextos educativos, e o teatro infantil de arte, espetáculos para crianças representados em contextos profissionais e comerciais por artistas adultos. Atrelado a isso, está o interesse em analisar os ecos contemporâneos dessa cisão.

Published: December 2019

A rastreabilidade no setor de rações reside nos aspectos da segurança alimentar, éticos e de responsabilidade comercial. Este trabalho responde a seguinte pergunta:“como propor um método de rastreabilidade em um sistema que possui muitas vulnerabilidades em seus processos?”. Através do conhecimento do processo, foi possível mapeá-lo e identificar as vulnerabilidade nele existentes, e com isso definir um plano de contigência para minimizar e/ou sanar os eventos de riscos identificados. Após realizadas as melhorias, foi proposta uma abordagem de rastreabilidade.

The growth of transition metal dichalcogenide (TMDC) alloys provides an
opportunity to experimentally access information elucidating how optical properties
change with gradual substitutions in the lattice compared with their pure
compositions. In this work, we performed growths of alloyed crystals with
stoichiometric compositions between pure forms of NbSe2 and WSe2, followed by an
optical analysis of those alloys by utilizing Raman spectroscopy and spectroscopic
ellipsometry.
GENIUS LOCI: CITY PLACE IMMUNITY

Published: December 2019

Complex social changes, mobility, progressive information and communication technological advancement, as global achievements of the modern era, lead to the transformation of space at the local level and change of the identity patterns of a place. Starting from the problem of loss of identity features of a place or inability to identify them in the contemporary context, through an extensive review of theoretical sources, the paper seeks to understand the meaning of both the spirit of place and the spirit of time. The model presented in the paper as a synthesis of theoretical research and the preferred approach to the resuscitation of the spirit of place, introduces new layers of meaning and interpretation of the spirit of place in a modern context, and is based on three key principles: assimilation, acculturation and adaptation.
Antagonism between parasites within snail hosts impacts the transmission of human schistosomiasis

Published: December 2019

Human disease agents exist within complex environments that have underappreciated effects on transmission, especially for parasites with multi-host life cycles. We examined the impact of multiple host and parasite species on transmission of the human parasite Schistosoma mansoni in Kenya. We show S. mansoni is impacted by cattle and wild vertebrates because of their role in supporting trematode parasites, the larvae of which have antagonistic interactions with S. mansoni in their shared Biomphalaria vector snails. We discovered the abundant cattle trematode, Calicophoron sukari, fails to develop in Biomphalaria pfeifferi unless S. mansoni larvae are present in the same snail. Further development of S. mansoni is subsequently prevented by C. sukari’s presence. Modeling indicated that removal of C. sukari would increase S. mansoni-infected snails by two-fold. Predictable exploitation of aquatic habitats by humans and their cattle enable C. sukari to exploit S. mansoni, thereby limiting transmission of this human pathogen.
Opioids modulate an emergent rhythmogenic process to depress breathing

Published: December 2019

How mammalian neural circuits generate rhythmic activity in motor behaviors, such as breathing, walking, and chewing, remains elusive. For breathing, rhythm generation is localized to a brainstem nucleus, the preBötzinger Complex (preBötC). Rhythmic preBötC population activity consists of strong inspiratory bursts, which drive motoneuronal activity, and weaker burstlets, which we hypothesize reflect an emergent rhythmogenic process. If burstlets underlie inspiratory rhythmogenesis, respiratory depressants, such as opioids, should reduce burstlet frequency. Indeed, in medullary slices from neonatal mice, the μ-opioid receptor (μOR) agonist DAMGO slowed burstlet generation. Genetic deletion of μORs in a glutamatergic preBötC subpopulation abolished opioid-mediated depression, and the neuropeptide Substance P, but not blockade of inhibitory synaptic transmission, reduced opioidergic effects. We conclude that inspiratory rhythmogenesis is an emergent process, modulated by opioids, that does not rely on strong bursts of activity associated with motor output. These findings also point to strategies for ameliorating opioid-induced depression of breathing.

Machine learning of symbolic compositional rules with genetic programming: dissonance treatment in Palestrina
Authors: Anders Torsten , Inden Benjamin
Published: December 2019

We describe a method for automatically extracting symbolic compositional rules from music corpora. Resulting rules are expressed by a combination of logic and numeric relations, and they can therefore be studied by humans. These rules can also be used for algorithmic composition, where they can be combined with each other and with manually programmed rules. We chose genetic programming (GP) as our machine learning technique, because it is capable of learning formulas consisting of both logic and numeric relations. GP was never used for this purpose to our knowledge. We therefore investigate a well understood case in this study: dissonance treatment in Palestrina’s music. We label dissonances with a custom algorithm, automatically cluster melodic fragments with labelled dissonances into different dissonance categories (passing tone, suspension etc.) with the DBSCAN algorithm, and then learn rules describing the dissonance treatment of each category with GP. Learning is based on the requirement that rules must be broad enough to cover positive examples, but narrow enough to exclude negative examples. Dissonances from a given category are used as positive examples, while dissonances from other categories, melodic fragments without dissonances, purely random melodic fragments, and slight random transformations of positive examples, are used as negative examples.
