The “Aidification” of National Experiences: Swedish-Supported Correspondence Education in Tanzania, ca 1960–1975
Authors: Glover Nikolas
Published: October 2019

This article deals with the foundational juncture in a 60-year long (and counting) relationship between Swedish and Tanzanian adult educators. It analyses how Swedish correspondence education methods and objectives were adapted as they entered the emerging field of foreign aid. Two educational institutions in Tanzania, in which Swedish funds and personnel played a central role are studied: the Nordic-funded Co-operative Educational Centre in Moshi founded in 1964, and the Swedish-funded National Correspondence Institute in Dar es Salaam (1971–). The analysis shows how international NGOs and individual policy entrepreneurs created the initial arenas for policy transfer. It emphasises how the ideal of creating an equal partnership affected the policies that were being lent and borrowed. The article argues that the concept of aidification can be used to capture the ways in which transnational policy areas such as education were transformed in the wake of decolonisation.

Foram identificados os sorovares de Salmonella isolados de materiais avícolas, provenientes de diferentes áreas· geográficas, durante o período de 1994 a 1999. Isolaram-se 73 sorovares no total, com reconhecimento de 21 sorovares diferentes, distribuídos em nove sorogrupos. O sorovar de maior incidência com 46,52% foi o enteritidis, proveniente de órgãos de frangos de corte, poedeiras e matrizes pesadas, embora não tenha sido isolado de ração, cama e nas farinhas de carne, de vísceras ou de peixe. O segundo sorovar de maior incidência foi o anatum com 6,84%, sendo que 80% do seu isolamento ocorreu em farinha de carne. AS. pullorum representou 2,73% dos isolamentos, ocorridos 100% em poedeiras vermelhas, confirmando sua maior susceptibilidade em relação à infecção por este sorovar. Frango de corte e farinha de carne foram os materiais analisados em que mais se encontraram Salmonella spp., com 41,09 e 30,13%, respectivamente, dos diferentes sorovares. Entre os sorovares isolados de frangos de corte, 83,34% corresponderam ao enteriridis, enquanto em farinha de carne este mesmo sorovar não foi detectado. A área geográfica responsável pelo maior isolamento de Salmonella spp. foi o Estado de São Paulo com 82,19%, seguido seqüencialmente pelo Estado do Maranhão com 8,21 %. O Estado de São Paulo foi responsável por 79,41% do isolamento de S. enteritidis. Apesar de o sorogrupo 0:9,12 apresentar o maior número de isolamentos justamente por nele estar inserido o sorovar de maior prevalência, o enteritidis, foi o sorogrupo 0:6,7 que apresentou a maior variação de sorovares. Demonstramos a importância do rastreamento epidemiológico da Salmonella em relação a indústria avícola, em virtude da importante posição das aves dentro da cadeia alimentar e do ciclo de propagação desta bactéria, envolvendo não só a sanidade avícola, mas também a saúde pública.

"مُعَدَّلات انتشار السلوك العدواني لدى عينة من تلاميذ المرحلة الابتدائية
في مدينة مصراتة"
Authors: النعاس عمر مصطفي , الطـــالب سالــمة أحمد
Published: October 2019

المدرسة هي البيت الثاني للتلميذ الذي يكون فيه علاقات اجتماعية بزملائه التلاميذ؛ بالإضافة إلى التعلم فيها, كما تعتبر المدرسة الأرض الخصبة أو المكان المناسب الذي يفرغ فيه الطفل طاقاته وشحناته, وما يحس به وما يؤثر على نفسيته, وخاصة بعد أن عاش الأطفال ظروف نفسية سيئة خلال فترة التحرير, مما اثر سلباً على قدراتهم وثقتهم بأنفسهم وشعورهم بالأمن مما أحسسهم بالإحباط, مما يدور حولهم وإدخالهم في بعض المشاكل النفسية ومن هذه المشاكل السلوك العدواني, ويقصد به الهجوم الصريح على الذات أو الآخرين, ويأخذ عدة أشكال منها اللفظي والبدني والمادي وقد يكون السلوك العدواني مباشر أو غير مباشر, كما أن له العديد من الأنماط لدى الأطفال في المرحلة الابتدائية. (إيهاب البيلاوي، 2004،22)
و إنَّه من الميسور دائماً الحكم على البالغين بالاضطراب وعدم النضوج عندما نلاحظ تقارباً بين أنواع ما يصدر منهم من سلوك وما يصدر عن الطفل، ففي مثل هذه الحالات نصفهم بعدم النضوج والاضطرابات بسبب صفاتهم الطفوليَّة، لكن عندما تصدر مثل هذه التصرُّفات من الطفل فإنَّها قد تكون مقبولة ومناسبة لعمره ومتطلَّبات النمو التي يمرُّ بها وما تتطلَّبه هذه المرحلة من تغيُّرات فكريَّة وانفعاليَّة واجتماعيَّة، لهذا يحذِر علماء العلاج النفسيِّ – السلوكي من الاندفاع في وصف طفل معيَّن بالاضطراب. ومن ثمَّ وجب على المعلِّم أن يكون ملمّاً بخصائص النمو وتطوُّر الطفولة ليسهل عليه معرفة ما يحتاج من سلوك الأطفال إلى تدخُّل بسبب شذوذه وعدم ملاءمته لمتطلَّبات النمو، أو ما يحتاج إلى التجاهل أو حتَّى التشجيع بسبب انسجامه مع تلك المتطلَّبات. (خالد خليل الشيخلي،2005،76).
إنَّ كثيراً من الاضطرابات كالعدوان والتحطيم والبكاء وهي المشكلات التي تسبِّب إزعاجاً للأسرة وللمعلِّمين قد تكون لدى كثير من الأطفال تعبيراً يتناسب مع الفترة الزمنيَّة التي يمرُّ بها الطفل، ومن ثمَّ فإنَّه لا يجوز وصفها بالشذوذ أو المرض أو المشاكسة، وبالمقابل فإنَّ كثيراً من المشكلات التي تصدر عن بعض الأطفال لا تكون مطلباً من مطالب النمو ولا تنسجم مع التطوُّر الزمنيِّ للطفل وما يصحبه من تطوُّر انفعالي أو عقلي أو اجتماعي ومثل هذه المشكلات قد يتفاقم بعضها لدرجة يمكن معها وصفها بالاضطراب. (خولة أحمد يحيى،2012،87).
والمدارس في مدينة مصراتة مثل أغلب المدارس في ليبيا تعاني من انتشار مظاهر السلوك العدواني وإن كانت لم تبلغ الحدود القصوى في العدوان, غير أن أهمية هذا السلوك تكمن في الآثار السلبية الناتجة عنه التي تطال التلاميذ وتهدد تماسك الأسرة والعلاقات بين الجماعات في المدرسة بين التلاميذ أنفسهم وبينهم وبين المعلمين. وقد توصلت دراسة قوس (2011) إلى وجود فروق دالة إحصائياً في مستوى العنف بين الطلبة والطالبات وأن مستوى العنف لدى الطلبة أعلى من مستوى العنف لدى الطالبات. ومن خلال ملاحظة الباحث لتلاميذ المرحلة الابتدائية يرى الباحث أن السلوك العدواني لتلاميذ المرحلة الابتدائية أصبح منتشراً في المدارس بشكل واضح من بعد حرب التحرير كنتيجة حتمية لما يواجها التلميذ من احباطات متكررة من البيئة المحيطة به من تهميش أو ظلم أو لامبالاة.
ومن هذا المنطلق قامت الباحث بإجراء البحث على أنماط السلوك العدواني الشائعة لدى تلاميذ المرحلة الابتدائية بمدينة مصراتة.

Risks assessment model for the sustainable built environment of finishing construction works
Authors: Tamošaitienė Jolanta , Lapeikytė Miglė
Published: October 2019

Construction works are among the riskiest activities in Lithuania. To develop a sustainable environment at a construction
site, risk factors must be first identified and then eliminated. Each case of a construction site, construction conditions and the project
environment is unique. Thus, risks must be individually assessed considering distinguishing features of the construction works and
the environmental conditions. Consequently, preconditions exist for the development of a new risk assessment model comprising risk
assessment norms, the construction project and conditions of the construction processes. Expert evaluation and the TODIM method
were used for the risk assessment of finishing works. Two construction sites were used to assess construction risks related to
finishing works. The article presents risk assessment results based on the riskiest job at a construction site of finishing works as well
as the line of priorities of the riskiest workplace.
Medium-band Photometry Reverberation Mapping of Nearby Active Galactic Nuclei
Authors: Kim Joonho , Im Myungshin , Choi Changsu , Hwang Sungyong
Published: October 2019

Reverberation mapping (RM) is one of the most efficient ways to investigate the broad-line region around the central supermassive black holes of active galactic nuclei (AGNs). A common way of performing the RM is to perform a long term spectroscopic monitoring of AGNs, but the spectroscopic monitoring campaign of a large number of AGNs requires an extensive amount of observing time of medium to large size telescopes. As an alternative way, we present the results of photometric RM with medium-band photometry. As the widths of medium-band filters match well with the widths of AGN broad emission lines, the medium-band observation with small telescopes can be a cost-effective way to perform RM. We monitored five nearby AGNs with available spectroscopic RM results showing days to weeks scale variability. Observations were performed for ∼3 months with an average of 3 days cadence using three medium-band filters on a 0.43 m telescope. The time lags between the continuum and the Hα emission line light curves are calculated using the JAVELIN software and the discrete correlation function. We find time lags of 1.5–15.9 days for these AGNs, which are consistent with the time lags derived from previous spectroscopic RM measurements. This result demonstrates that even a 0.5 m class telescope can perform RM with medium-bands. Furthermore, we show that RM for tens of thousands AGNs is possible with a dedicated 1 m class telescope.
The Inside-out Growth of the Galactic Disk

Published: October 2019

We quantify the inside-out growth of the Milky Way’s low-α stellar disk, modeling the ages, metallicities, and Galactocentric radii of APOGEE red clump stars with 6 kpc < R < 13 kpc. The current stellar distribution differs significantly from that expected from the star formation history due to the redistribution of stars through radial orbit mixing. We propose and fit a global model for the Milky Way disk, specified by an inside-out star formation history, radial orbit mixing, and an empirical, parametric model for its chemical evolution. We account for the spatially complex survey selection function, and find that the model fits all data well. We find distinct inside-out growth of the Milky Way disk; the best-fit model implies that the half-mass radius of the Milky Way disk has grown by 43% over the last 7 Gyr. Yet, such inside-out growth still results in a present-day age gradient weaker than 0.1 Gyr kpc−1. Our model predicts the half-mass and half-light sizes of the Galactic disk at earlier epochs, which can be compared to the observed redshift–size relations of disk galaxies. We show that radial orbit migration can reconcile the distinct disk-size evolution with redshift, also expected from cosmological simulations, with the modest present-day age gradients seen in the Milky Way and other galaxies.
A Particle Module for the PLUTO Code. III. Dust
Authors: Mignone A. , Flock M. , Vaidya B.
Published: October 2019

Implementation of a new particle module describing the physics of dust grains coupled to a gas via drag forces is the subject of this work. The proposed particle–gas hybrid scheme has been designed to work in Cartesian as well as in cylindrical and spherical geometries. The numerical method relies on a Godunov-type second-order scheme for the fluid and an exponential midpoint rule for dust particles, which overcomes the stiffness introduced by the linear coupling term. Besides being time-reversible and globally second-order accurate in time, the exponential integrator provides energy errors that are always bounded, and it remains stable in the limit of arbitrarily small particle stopping times, yielding the correct asymptotic solution. Such properties make this method preferable to the more widely used semi-implicit or fully implicit schemes at a very modest increase in computational cost. Coupling between particles and grid quantities is achieved through particle deposition and field-weighting techniques borrowed from particle-in-cell simulation methods. In this respect, we derive new weight factors in curvilinear coordinates that are more accurate than traditional volume or area weighting. A comprehensive suite of numerical benchmarks is presented to assess the accuracy and robustness of the algorithm in Cartesian, cylindrical, and spherical coordinates. Particular attention is devoted to the streaming instability, which is analyzed in both local and global disk models. The module is part of the PLUTO code for astrophysical gas dynamics, and it is mainly intended for the numerical modeling of protoplanetary disks in which solid and gas interact via aerodynamic drag.
Puffy Accretion Disks: Sub-Eddington, Optically Thick, and Stable

Published: October 2019

We report on a new class of solutions of black hole accretion disks that we have found through three-dimensional, global, radiative magnetohydrodynamic simulations in general relativity. It combines features of the canonical thin, slim, and thick disk models but differs in crucial respects from each of them. We expect these new solutions to provide a more realistic description of black hole disks than the slim disk model. We are presenting a disk solution for a nonspinning black hole at a sub-Eddington mass accretion rate,

. By the density scale-height measure the disk appears to be thin, having a high density core near the equatorial plane of height

, but most of the inflow occurs through a highly advective, turbulent, optically thick, Keplerian region that sandwiches the core and has a substantial geometrical thickness comparable to the radius, H ∼ r. The accreting fluid is supported above the midplane in large part by the magnetic field, with the gas and radiation to magnetic pressure ratio β ∼ 1, this makes the disk thermally stable, even though the radiation pressure strongly dominates over gas pressure. A significant part of the radiation emerging from the disk is captured by the black hole, so the disk is less luminous than a thin disk would be at the same accretion rate.

Published: October 2019

Introduction: Over the past decades, prevalence of biofilm-forming Staphylococcus aureus strains has significantly increased in urinary tract infections. The aim of this study was to investigate prevalence of biofilm forming and adhesion encoding genes and to analyze distribution of different agr and spa types in S. aureus isolates.

Methodology: In the present study, 75 S. aureus isolates obtained from patients with urinary tract infections were examined for susceptibility to antimicrobial agents. Adhesion, biofilm, and spa encoding genes were detected by PCR screening; agr types were determined using multiplex PCR.

Results: Among the 75 isolates, 72% were biofilm producers and 28% were non-biofilm producers. Notably, the ability to produce biofilm was higher among MRSA strains ompared to MSSA strains. The most prevalent biofilm forming gene was icaD (77.3%), followed by icaA (76%), icaB (57.3%) and icaC (50.7%). Adhesion genes clfA, clfB, fnbB, can, fnbA, ebp and bap were detected in 94.7%, 92%, 68%, 64%, 64%, 60% and 5.3% of the isolates, respectively. The spa types t426 and t7789 were found among the non-MDR isolates. It was found that t790, t084, t7789 and t325 spa types were biofilm producers, while t426 and t1339 spa types were non-biofilm producers.

Conclusion: Biofilm encoding genes icaD and spa type t790 and agr type III were the most prevalent factors among MDR biofilm producer isolates. The study emphasized that identification of genes and characterization of molecular types involved in biofilm formation should be considered.

Saxifraga damingshanensis (Saxifragaceae), a new species from Damingshan Nature Reserve in Guangxi Province, is described and illustrated. A morphological comparison between the new species and its putative relatives, S. mengtzeana and S. luoxiaoensis, is presented. The new species is morphologically similar to S. mengtzeana, but it can be easily distinguished by its non-peltate leaf, both surfaces of mature leaf blade covered with white glandular trichome, petals 3-veined and margin entire. Phylogenetic analysis, based on two chloroplast DNA regions (matK and psbA-trnH), confirmed that the new species belongs to S. sect. Irregulares. The new species is currently only known from Damingshan, Guangxi and we assign it an IUCN Red List preliminary status as Data Deficient.
Studygrammers: Learning influencers

Published: October 2019

Present learning ecologies are diverse and change quickly, which demands a similar observation of the phenomenon. This paper is focused on the youth emerging informal learning communities and the study’s object is to discover and characterize a new figure in this landscape, the Studygrammer. With surveys (N=256), focus groups carried out through the Philips 66 technique and analyze with Atlas ti software (thematic analysis) we analyze: practices of academic social media use amongst Communication students and apart of the institutional enviroment, plus their opinions regarding the #Studygram community, #Studygrammer profiles from different degrees are also analyzed. Main results help us to concrete a definition for Studygrammer: a student that performs a mentoring (coach-leader) role amongst peers using Instagram, not only sharing notes (highly performed) but also tips, inspiration and experiences. They have the DNA of an influencer using the same visual code and monetizating their practices but the academic goal adds some peculiarities: the visual code works as lingua franca between different knowledge areas (students of a certain degree follow studygrammers which study different degrees, because they are also interested on the know-how learning process) and in the followers’ adhesion criteria we find more rational than emotional reasons.

Las actuales ecologías de aprendizaje destacan por su variedad, dinamismo y mutabilidad, lo que requiere una observación análoga de las mismas. Este trabajo se centra en las culturas de aprendizaje informal juvenil emergentes, tomando como objetivo principal reconocer y caracterizar una nueva figura en medios sociales en línea: el estudigramer. Empleando cuestionarios (N=256), grupos de discusión organizados mediante Philips 66 (N=56) y Atlas.ti (análisis temático), y observación participante, se analizan: prácticas de uso académico en redes sociales por parte de estudiantes de Comunicación al margen del entorno institucional, la opinión sobre la comunidad #Studigram, y el análisis de perfiles. Los principales resultados se concentran en una propuesta de definición del estudigramer: véase aquel estudiante que ejerce la labor de mentor y líder entre pares del ámbito académico en Instagram. Este perfil no solo comparte apuntes (que sobresalen por su orden y detallada estética), sino que también transmite consejos, apoyo y experiencias. De hecho, el estudigramer mantiene la genética influencer al priorizar la estética y monetización en sus publicaciones. Se concluye que el fin académico añade características exclusivas a la comunidad, donde el código visual funciona como lengua franca entre ámbitos de estudio. En efecto, los estudigramers cuentan con seguidores de diversos grados académicos que buscan el «saber hacer» (gestión y planificación del aprendizaje), así como una adhesión fundamentalmente racional.
SELF-RIGHTING CRAFT – BASIC PRINCIPLES AND DESIGN REQUIREMENTS
Authors: Thatcher K C
Published: October 2019

Records show that the naval architecture of self-righting has been known and understood for at least two hundred years. For much of this time its application was limited to small, shore based, rescue boats, but the past few decades have seen the provision of self-righting capability widen into a diverse range of craft from offshore standby vessels to trans-ocean rowing boats. Whatever the size and use, the aim is always the same – to provide safe refuge for the crew by incorporating a mechanism whereby the vessel will return upright following a knockdown or capsize.

Despite this growing popularity, self-righting vessel design is still viewed by some naval architects with suspicion. The purpose of this paper is to provide a background to self-righting methods and basic guidance on design, testing and outfit requirements. Although much of the content has been based on the author’s experience with rescue craft, it should be noted that the principles and techniques described are applicable to all types of vessel.

Published: October 2019

In this article, a cognitive framework for observing learning activities based on human-computer coupling is proposed. The observation is based on the vectorization of a learning situation along with human-computer interaction factors. An evolutionary high-dimensional topology of learning cognitive flow is introduced for human-computer interaction. In addition, the authors have selected a tree topology as the topological structure of a low-dimensional learning space to process the observations for online learning. Furthermore, the mechanism for the BSM (brain cognitive body-situation of coupling-manifold of information) the coupling morphism is presented. The principle for the coupled observation of objects in a cognitive or learning manifold is proposed. Finally, a special system for teaching and learning is programmed to observe and evaluate learning and mental arithmetic training processes. This system not only provides students with a new ergonomic learning model but also records the students' learning processes. Thus, the teachers can summarize the knowledge points automatically rather than manually.

Authors: Shen Huajie , Liu Teng , Zhang Yueqin
Published: October 2019

This study aims to create learning path navigation for target learners by discovering the correlation among micro-learning units. In this study, the learning path is defined as a sequence of learning units used to realize a learning goal, and a period used for realizing the learning goal is regarded as a learning cycle. Furthermore, the learning unit datasets are extracted according to the learning cycle. In order to discover the correlations of learning units, we proposed an algorithm named Bayesian Network Association Rule (BNAR), which is used to establish a dynamic learning path according to the learning history of reference learners group who achieved learning goals. Based on the successful learning history, the dynamic learning path navigation will help target learners to improve learning efficiency.
Improving the Performance of kNN in the MapReduce Framework Using Locality Sensitive Hashing
Authors: Bagui Sikha , Mondal Arup Kumar , Bagui Subhash
Published: October 2019

In this work the authors present a parallel k nearest neighbor (kNN) algorithm using locality sensitive hashing to preprocess the data before it is classified using kNN in Hadoop's MapReduce framework. This is compared with the sequential (conventional) implementation. Using locality sensitive hashing's similarity measure with kNN, the iterative procedure to classify a data object is performed within a hash bucket rather than the whole data set, greatly reducing the computation time needed for classification. Several experiments were run that showed that the parallel implementation performed better than the sequential implementation on very large datasets. The study also experimented with a few map and reduce side optimization features for the parallel implementation and presented some optimum map and reduce side parameters. Among the map side parameters, the block size and input split size were varied, and among the reduce side parameters, the number of planes were varied, and their effects were studied.

Published: October 2019

The Ambient Assisted Living (AAL) domain aims to support the daily life activities of elders, patients with chronic conditions, and disabled people. Several AAL platforms have been developed over the last two decades. Hence, there is a need to identify Quality Criteria (QC) and make it well defined in order to achieve the AAL system purposes. To be able to convince all stakeholders including both technologies and end users of AAL systems, high quality must be guaranteed. The goal of this article is to obtain a set of data quality characteristics that would be applicable to AAL system, and have its performance evaluated using sensors' data. To this end, this work uses the ISO/IEC 25012 and ISO/IEC 25010 standards to extract the most relevant criteria that are apt for AAL systems. As a result, an evaluation approach on an indoor localization platform was made, and an evaluation procedure has been established. This is done by first generating a hierarchical data quality model, and have it evaluated using the metrics, based on the sensors data and the concept of fuzzy logic.
Predictors of the Continued Adoption of WECHAT Mobile Payment
Authors: Mensah Isaac Kofi
Published: October 2019

This research article integrates the technology acceptance model and diffusion of innovation theory to explore the factors predicting the continuance intention to use WECHAT mobile payment services in China. The results showed that perceived usefulness, perceived ease of use, perceived service quality, social influence, internet self-efficacy, relative advantage, compatibility, and complexity of were all significant predictor of the continued intention to use WECHAT mobile payment services. However, trust in the internet was not significant determinants of the continued intention to use. The results also demonstrated that internet self-efficacy is a predictor of perceived ease of use, relative advantage, compatibility and complexity of mobile payment services. Again, perceived ease of use and social influence were found to have a significant impact on the perceived service quality of WECHAT mobile payment. The implications of these findings on the adoption of mobile payments are discussed.

Despite the existence of architectural models that can be used as references to build AAL systems, their selection for new AAL projects is a difficult task. In this work, the authors present the state of the art on Reference Architectures (RA) and Reference Models (RM) found through the conduction of a systematic literature review. The authors identified, analyzed, and assessed 24 existing RA&RM for AAL domain, and, as result, the authors spotted interesting research directions that should be further explored to improve existing and future RA&RM and software systems for that domain.

Authors: Abburu Sunitha
Published: October 2019

The research aims at design and develop a special semantic query engine “CityGML Spatial Semantic Web Client (CSSWC)” that facilitates ontology-based multicriteria queries on CityGML data in OGC standard. Presently, there is no spatial method, spatial information infrastructure or any tool to establish the spatial semantic relationship between the 3D city objects in CityGML model. The present work establishes the spatial and semantic relationships between the 3DCityObjects and facilitates ontology-driven spatial semantic query engine on 3D city objects, class with multiple attributes, spatial semantic relations like crosses, nearby, etc., with all other city objects. This is a novel and original work practically implemented generic product for any 3D CityGML model on the globe. A user-friendly form-based interface is designed to compose effective ontology based GeoSPARQL query. CSSWC enhances CityGML applications performance through effective and efficient querying system.

Para instruir a mocidade: lógica e moral em lições no compêndio de filosofia, de José Soriano de Souza
Authors: Santos Anderson , Teixeira Corrêa Rosa Lydia
Published: October 2019

Neste trabalho temos como objetivo apresentar algumas considerações sobre duas lições presentes no compêndio Lições de philosophia elementar racional e moral, de José Soriano de Souza, publicado em 1871 na cidade do Recife. Ele destinou a maior parte da sua vida às atividades intelectuais e públicas. Seus estudos básicos ocorreram no Lyceu Provincial da Parahyba do Norte. Em seguida formou-se em medicina na Faculdade de Medicina do Rio de Janeiro (1860), e, por fim, em filosofia (1866), pela Universidade de Louvain, na Bélgica. Foi lente catedrático da Faculdade de Direito do Recife onde lecionou as disciplinas direito público e constitucional, direito natural e direito romano. Após movimentado concurso (1867), obteve a cadeira de filosofia do Gymnásio Pernambucanona qual teve como concorrente Tobias Barreto, uma figura já conhecida naquela época. A partir dessa obra, temos como objetivo analisar entre as lições presentes no compêndio, duas, sendo uma delas sobre lógica e a outra sobre a moral. Com isso, observamos que o autor participou da produção de saberes por meio de prescrições contidas nas lições que analisamos, interferindo na cultura escolar inerente à instituição na qual lecionava.
Histórias dos conservatórios brasileiros de canto orfeônico: consonâncias e dissonâncias nos cursos de formação do professorado de música
Authors: Souza dos Santos Elias , Ferronato Cristiano de Jesus , Mecenas Ane
Published: October 2019

Este artigo objetiva apresentar e analisar alguns aspectos das histórias dos conservatórios brasileiros de canto orfeônico, instituições responsáveis pela formação, em nível superior, do professorado de música das escolas públicas e particulares. A pesquisa, de caráter histórico, bibliográfico e oral, está ancorada nos conceitos de ‘instituições educativas’ e ‘currículo’. As trajetórias dessas escolas se apresentaram, por um lado, de forma diversificada e, por outro, denotaram o controle do Estado ante as diretrizes nacionais, tanto na formação do(as) docentes quanto na organização dos conteúdos programáticos da disciplina canto orfeônico. A investigação destaca a importância e o pioneirismo dessas instituições no processo de formação dos primeiros docentes de música voltados ao ensino da educação musical escolar no Brasil. Os percursos históricos de alguns conservatórios evidenciaram silêncios e ausência de produção acadêmica, apesar dos esforços de pesquisadores na publicização de trabalhos acadêmicos em eventos no país.

Authors: Pereira Alisson José da Silva Esteves , Musial Gilvanice Da Silva
Published: October 2019

Neste artigo analisaremos as táticas produzidas na localidade Vera Cruz – Pindahybas para a permanência da escola de instrução primária, após a lei 281 de 1899, bem como o trabalho de Maria Estephania de Macedo, professora da cadeira entre 1901 e 1909. Analisaremos, ainda, aspectos referentes ao ensino e observaremos que todo o processo escolar organizado na cadeira primária de Maria Estephania de Macedo foi fundamental para a não supressão da cadeira na localidade. Para a realização deste trabalho, utilizaremos a legislação mineira, relatórios da Secretaria do Interior, dentre outros. E, para trabalhar com estas fontes, utilizamos os conceitos de estratégias e táticas de Michel de Certeau para compreendermos as táticas locais que auxiliaram na permanência dessa escola e as estratégias políticas que visavam suprimir as escolas rurais e distritais mineiras.

Authors: Silva Juan Carlo Cruz , Medeiro Neta Olívia Morais
Published: October 2019

No presente trabalho realizamos uma análise historiográfica da obra História do ensino industrial no Brasil, de autoria do educador-engenheiro Celso Suckow da Fonseca (1905-1966). Utilizamos o método histórico, conforme descrito por Rüsen (2015), buscando compreender os pressupostos teórico-metodológicos que nortearam a obra. Os entendimentos de intelectual, lugar social e escrita da história são referenciais para a análise da fonte. Diante da sua atuação em diversos papéis no campo da educação profissional no Brasil, Suckow apresenta indícios de sua escrita engajada.  A partir das matrizes interpretativas, propostas por Xavier (2011), apontamos elementos da matriz político-institucional na obra analisada, mas concomitantemente às matrizes sociológica e político-ideológicas.

È morto Ippocrate, lunga vita a Ippocrate. Per una rivalutazione del paradigma medico ippocratico
Authors: Mingardo Letizia
Published: October 2019

Nel panorama bioetico contemporaneo trova credito l’idea per cui la tradizione ippocratica sarebbe ormai irrimediabilmente anacronistica ed inevitabilmente superata, come, ad esempio, sostengono autori quali Veatch, Riha, Heubel e Mori. Le ragioni profonde di questa ostilità rimandano al divieto di pratiche abortive e di atti finalizzati a provocare la morte, contenuti nel Giuramento di Ippocrate, nonché, più in generale, alla commistione con l’etica cristiana che la storia dell’ippocratismo racconta. Nel presente contributo intendo mostrare come il movimento anti-ippocratico contemporaneo si nutra di una nozione di ippocratismo affetta da una certa stereotipia, e così ricostruita allo scopo di accreditare l’opposto paradigma pro-choice. Il mio intento finale è quello di offrire alcuni spunti per una riconsiderazione del paradigma medico ippocratico, alla luce dell’apprezzamento di quelli fra suoi elementi costitutivi che possono definirsi “classici”. Dopo un breve ritorno alle origini storiche dell’ippocratismo, mi soffermerò sul primo Aforisma di Ippocrate, in quanto manifesto epistemologico della medicina ippocratica, e sul Giuramento, in quanto manifesto deontologico della professione medica ippocratica. A traghettarmi dall’Aforisma al Giuramento, a cavallo tra epistemologia e deontologia, sarà una specifica riflessione sulla concezione ippocratica del rapporto tra medico e paziente, così come emergente anche da altre fonti antiche. Nel compiere questo percorso, sarò supportata da autorevoli voci, che, nell’odierno panorama nazionale e internazionale, contribuiscono ad alimentare una sempre più attenta rivalutazione della tradizione ippocratica, sotto il profilo etico e deontologico.
Clinical Spectrum of Cutaneous Adverse Drug Reactions
Authors: Agrawal Ankita , Ghate Smita , Gupta Abhishek Kumar , Dhurat Rachita
Published: October 2019

Background:

Cutaneous adverse drug reactions (CADRs) are common, comprising 10%–30% of all reported adverse drug reactions (ADRs) and its incidence in hospitalized patients is 2%–3%.

Aims:

The aim is to study the different clinical spectrum of CADRs in outpatient and inpatient and to find out the offending drug.

Settings and Design:

A prospective observational, nonrandomized hospital-based study was conducted at a tertiary care hospital over a period of 12 months.

Materials and Methods:

Patients presenting with suspected drug-related cutaneous lesions were included if drug identity could be ascertained. Clinical profiling was done. The severity of the reaction was assessed using modified Hartwig and Siegel ADR severity assessment scale.

Statistical Analysis Used:

Data were analyzed using Stata Version 13.

Results:

Out of the total study population, most commonly observed cutaneous ADRs were fixed drug reaction in 28.75%, followed by maculopapular drug rash in 26.3%, and urticarial rash in 20.6%. Few less frequently observed CADRs were a lichenoid eruption, acneiform eruption, and baboon syndrome, generalized pruritus, pityriasis rosea, and vasculitis. Antimicrobials accounted for 37.5% of the total followed by nonsteroidal anti-inflammatory drugs 25%, anti-epileptics 12.5%, and antifungal 6.25%. Anti-retroviral therapy contributed 3.125%, whereas 1.875% were due to Anti-Koch's therapy. About 28.1% of patients were taking monotherapy, whereas 71.9% of patients were received polytherapy.

Conclusions:

Wide spectrums of drug reaction were observed in this study. Sound knowledge of these drug eruptions may help the clinician to diagnose and effectively manage their cases. Polypharmacy is a well-known predictor of ADRs in children and adults.
A Hospital-Based Observational Study on the Frequency of Different Skin Diseases and Patterns of Topical Steroid Misuse
Authors: Ahmed Ghazal , Mishra Dharmendra Kumar
Published: October 2019

Background:

Over-the-counter (OTC), unlabeled steroids are widely available as cosmetics and have been a recent area of interest in research and clinical practice due to the side effects. However, less is known about OTC-labeled steroid misuse for various cutaneous diseases at a primary care or community level.

Objective:

The present study was aimed to assess the frequency of different skin diseases and patterns of topical steroid (TS) misuse in them.

Materials and Methods:

All new patients attending dermatology outpatient department (OPD) on 6 random OPD days in November 2016 for skin diseases were inquired about the use of any unsupervised steroid-containing medication on their skin lesions. The diagnosis and the prescription of the chief consultant/faculty for the disease were also screened in the context of steroid prescription. Data were presented in absolute number and percentage scale, and risk of misuse was analyzed using INSTAT software.

Results:

A total of 463 patients with a mean age of 27.01 ± 14.57 years (range 3 months to 92 years) were included. The majority (66.09%) were male. The most common disease was infectious in nature (933.19%) of which tinea infection was the most common (22.69%). A total of 119 (25.70%) patients had used unsupervised and OTC TSs; 4.20% presented with steroid dermatitis. Misuse was highest in photodermatitis and melasma (60 and 50%, respectively). TS misuse was more common in 15–40 years' age group and in diseases affecting face (relative risk 1.64 and 1.70, respectively; P < 0.01). Gender was not a risk factor.

Conclusion:

TS misuse is rampant (25.70%), and steroid dermatitis is a frequent complication. Patients aged 15–40 years and those with diseases affecting face are at risk of misusing it.
