El potencial de las aplicaciones educativas en el proceso de evaluación formativa
Authors: Lustosa de Oliveira Mayara , Vega Garzón Juan Carlos , Silva Thanuci , Galembeck Eduardo
Published: December 2017

El debate sobre los objetivos reales de la evaluación no es nuevo. Sin embargo, todavía predominan aspectos como la excesiva valoración de la memoria, lo que refleja una visión tradicional y limitada. Es necesario superar el uso exclusivo de la evaluación tradicional con el fin de adoptar una evaluación formativa, modalidad que busca identificar las fallas y necesidades de los estudiantes durante el proceso educativo con el fin de recibir retroalimentación para tomar las medidas necesarias que permitan mejorar la enseñanza y el aprendizaje. Siguiendo esta necesidad, y buscando ayudar a los profesores en la aplicación de una evaluación formativa, algunos recursos tecnológicos han sido desarrollados. El presente trabajo tiene como objetivo describir el potencial de tres aplicaciones (Armet, The Cell y 3DClass) en el proceso de evaluación formativa usando las bases de datos asociadas a cada aplicación. Los resultados muestran que estas aplicaciones proporcionan métricas de evaluación más transparentes, coherentes y que permiten al profesor sistematizar criterios e indicadores, lo que reduce la subjetividad del proceso de evaluación formativa y el tiempo necesario para la preparación, tabulación y análisis de datos. Gracias a que con esta tecnología es posible verificar en tiempo real el número de errores totales y por pregunta preguntas con el mayor número de errores recurrentes, preguntas con el mayor y menor índice de aciertos y el tiempo que los alumnos emplean para desarrollar la actividad, es posible determinar el progreso de los alumnos a lo largo del tiempo e identificar puntualmente dónde ocurren los errores; esto permite una investigación minuciosa sobre sus posibles causas. Esta información facilita la retroalimentación para los alumnos, ya sea como intervenciones puntuales o direccionadas por parte del profesor.
Adaptación del instrumento metodológico de la representación del contenido (ReCo) al marco teórico del CTPC
Authors: Candela Boris Fernando
Published: December 2017

Desde mediados de la década de los ochenta, la comunidad de educación en ciencias se ha interesado en que los profesores identifiquen y desarrollen el conocimiento pedagógico del contenido (CPC). Para ello, se han diseñado programas de educación desde una perspectiva por “orientación reflexiva”, estructurados a partir de un conjunto de actividades de formación cuyas tareas se centran en la práctica del diseño de ambientes de aprendizaje de contenidos específicos, en los cuales el instrumento metodológico de la representación del contenido (ReCo) ha jugado un papel crítico. La estructura lógica de este brinda la posibilidad a los profesores de tomar conciencia de los elementos teóricos y metodológicos que fundamentan el CPC. Por otro lado, con la emergencia al primer plano de las tecnologías digitales como instrumento de representación de los contenidos y gestión efectiva del aula, se genera la necesidad de transformar el constructo del conocimiento pedagógico del contenido (CPC) a conocimiento tecnológico y pedagógico del contenido (CTPC). En este sentido, resulta pertinente adaptar la estructura epistemológica de la ReCo al marco teórico del emergente constructo del CTPC, con el fin de que este instrumento continúe siendo utilizado como una heurística clave en los programas de educación donde la práctica del diseño de ambientes de aprendizaje resulta importante para el desarrollo profesional de los profesores. Desde luego, la adaptación de la ReCo a la perspectiva del CTPC viene acompañada por una conceptualización de cad uno de los 12 ítems que la configuran con el fin de ilustrar a los enseñantes durant el desarrollo de estos.

Authors: Silva Edilaine Almeida Oliveira , Baptista Geilsa Costa Santos
Published: December 2017

Se presentan los resultados de un estudio colaborativo realizado con una profesora de un colegio público del estado de Bahía (nordeste de Brasil). El objetivo central del trabajo era elaborar un recurso didáctico que pudiera ser utilizado en la enseñanza de la biología basada en el diálogo intercultural entre los saberes que circulan en la vida cotidiana y los saberes adquiridos mediante formación escolar. Dicho de otro modo, esta didáctica de la biología vincula el conocimiento heredado culturalmente de los estudiantes con el conocimiento escolar sobre temas del área, en este caso, los hongos. La primera fase del estudio consintió en aplicar un cuestionario a los estudiantes de este colegio y, a partir de la información allí recopilada, se elaboraron tablas de cognición comparada. En estas fueron puntuadas relaciones de semejanza y diferencia entre los conocimientos previos de los estudiantes y el conocimiento biológico escolar. Los resultados de esta comparación revelaron relaciones entre estas dos formas de conocimiento, siendo imperativas las relaciones de semejanza, las cuales fueron importantes para el planeamiento y la construcción de un juego didáctico. La siguiente fase del estudio, consistió en aplicar el recurso didáctico diseñado en las aulas de la profesora participante para analizar su viabilidad en intervenciones pedagógicas basadas en el diálogo intercultural, entre las concepciones previas de los estudiantes y el conocimiento científico escolar sobre los hongos.

A contemporary approach to performance evaluation: Teacher portfolios
Performans değerlendirmesinde çağdaş bir yaklaşım: Öğretmen dosya değerlendirmesi
Authors: Toptaş Burcu
Published: December 2017

The aim of this study is discussing teacher portfolio’s areas of usage, purposes, benefits and limits as audit approach. This study is a review article and it helps analyzing the evaluation of teacher portfolio. In this direction, the areas of usage of teacher portfolio has been examined and its benefits and limits has been tried to determined as a result of literature review.  Portfolio is considered to be an approach used for the evaluation of only students. However, in many world countries, teacher portfolio is benefited from for the evaluation of teacher candidates in higher education. As a matter of fact, teacher file evaluation has a wide range of usage pre-service and in service. On the other hand, it is observed that this application is not common in terms of higher education in Turkey and enough amount of research has not been conducted on the application. Although this kind of attempts on the evalution of teacher candidates exist by Ministry of National Education, but effectiveness of it has not been evaluated. Therefore, it is crucial to determine in which situations teacher portfolio should be used, what evaluation criterion, benefits and limits are. It has been suggested that researchs should be conducted in order to be determined the efficiency in use of the approach applied by MoNE, and to be made improvements in this direction.Extended English abstract is in the end of Full Text PDF (TURKISH) file. ÖzetBu çalışmanın amacı, öğretmen dosya değerlendirmesinin (portfolyo) bir denetim yaklaşımı olarak kullanım alanlarını, amacını, faydaları ve sınırlılıklarını tartışmaktır.

Bu doğrultuda öğretmen dosya değerlendirmesinin kullanım alanları incelenmiş, faydaları ve sınırlılıkları alanyazın taraması neticesinde tespit edilmeye çalışılmıştır. Dosya değerlendirmesi, yalnızca öğrencilerin değerlendirilmesinde kullanılan bir yaklaşım olarak düşünülmektedir. Ancak dünyanın birçok ülkesinde, yükseköğretimde öğretmen adaylarının değerlendirilmesinde dosya değerlendirmesinden yararlanılmaktadır.  Nitekim öğretmen dosya değerlendirmesinin hizmet öncesi ve içinde çok yaygın bir kullanım alanı bulunmaktadır. Buna karşın Türkiye’de yükseköğretim açısından bu uygulamanın yaygın olmadığı ve uygulama ile ilgili yeterli araştırmanın yapılmadığı görülmektedir. Aday öğretmenlerin değerlendirilmesinde ise Milli Eğitim Bakanlığının bu tür bir çalışmasının olduğu görülse de henüz etkililiği değerlendirilmemiştir. Bu nedenle öğretmen dosya değerlendirmesinin hangi durumlarda kullanılacağının, değerlendirme ölçütlerinin neler olduğunun, fayda ve sınırlılıklarının belirlenmesi önemli görülmektedir. Bakanlık tarafından uygulanan bu yaklaşımının uygulamadaki etkililiğinin tespit edilmesi için araştırmaların yürütülmesi ve bu doğrultuda uygulamanın geliştirilmesi önerilmektedir.
Snorkel

Published: December 2017

Labeling training data is increasingly the largest bottleneck in deploying machine learning systems. We present Snorkel, a first-of-its-kind system that enables users to train state-of-the-art models without hand labeling any training data. Instead, users write labeling functions that express arbitrary heuristics, which can have unknown accuracies and correlations. Snorkel denoises their outputs without access to ground truth by incorporating the first end-to-end implementation of our recently proposed machine learning paradigm, data programming. We present a flexible interface layer for writing labeling functions based on our experience over the past year collaborating with companies, agencies, and research labs. In a user study, subject matter experts build models 2.8X faster and increase predictive performance an average 45.5% versus seven hours of hand labeling. We study the modeling tradeoffs in this new setting and propose an optimizer for automating tradeoff decisions that gives up to 1.8X speedup per pipeline execution. In two collaborations, with the U.S. Department of Veterans Affairs and the U.S. Food and Drug Administration, and on four open-source text and image data sets representative of other deployments, Snorkel provides 132% average improvements to predictive performance over prior heuristic approaches and comes within an average 3.60% of the predictive performance of large hand-curated training sets.
PVD Coatings on Bearing Steels for Aerospace Applications
Authors: Mueller Dieter , Kukla Holger , Schlosser Fabian , Hruby Hynek , Lartz Marcus , Voss Eckard
Published: December 2017

Physical vapor deposition (PVD) coating processes are used in many industrial fields to improve the surface properties of metallic components and tools. Due to the high hardness and low friction values obtained by PVD coatings, the reduction of wear rates and the protection against fretting and sliding fatigue are the main drivers for the application of this kind of technology. The current paper will point out the importance of PVD coatings for rolling bearings being used in the aerospace industry. High-speed rolling bearings are part of turbine engines. In these bearings, two different applications of PVD coatings are applied for the generation of suitable surfaces. Titanium nitride, as a hard, wear-protecting coating, is applied on the land-riding surface of rolling bearings to give enhanced reliability against fretting and severe damage in the case of bearing failure. Coatings with good friction properties are often demanded on rolling elements of aerospace bearings. Examples for these kinds of coatings are diamond-like carbon and molybdenum disulfide-based coatings. The coating techniques that are primarily used—arc evaporation and magnetron sputtering—are described in the paper as well as the obtained properties of the coatings.
Assessment of Advanced Aerospace Bearing Steel RCF Performances Using a Discriminating Multicontact Test

Published: December 2017

“Flat-washer” or “Unisteel” testing is a well-known technique applied to the basic selection of aircraft bearing materials and their heat treatment prior to, or as an alternative to, full-scale testing. Over the last decade, the continuous decrease of the development cycle time has constrained the aerospace bearing industry to revise its testing means. A simple, rapid, and reproducible test to assess material performance is then crucial, and many testing developments have been made. A history of this elemental screening method is presented to highlight its virtues and its shortcomings. The conclusions of these past developments have been used to design an enhanced version of this material test method called the multicontact test (MCT). A performance comparison is made with previously presented devices to bring out the discriminating power of the MCT concept and its capacity to obtain a statistically significant quantity of data relatively quickly and economically. A typical study is described in this paper to illustrate the performance of the MCT. The study shows the influence of the hardness change of a powder-metallurgy steel on rolling contact fatigue life.
High-Performance Bearing Steels: A New Approach in Alloy Development
Authors: Clausen Brigitte , Karsch Torben , Zoch Hans-Werner
Published: December 2017

A joint research project of the Institute of Ferrous Metallurgy, RWTH Aachen University; the Institute of Materials Science and Engineering, Kaiserslautern; the Gear Research Centre, Munich; and the Foundation Institute of Materials Science (IWT), Bremen, named “HiPerComp: High Performance Components,” resulted in new damage-tolerant steels for rolling bearing and gear applications. The main target of the project was the introduction of strengthening mechanisms and localized plasticity to common through-hardening bearing and case carburizing grades. These microstructural-based mechanisms were expected to reduce the sensitivity against nonmetallic inclusions and by that increase the bearing life. For a 52100 bearing steel, an aluminum addition of up to 2 mass% should develop the capability of transformation-induced plasticity effects as well as a further strength increase by k-carbides. For case-hardening grades such as ISO 18CrNiMo7-6 (comparable to AISI 4820), a copper addition was investigated, which can lead to the formation of coherent copper clusters, thus increasing the strength. Although the new alloys were developed at the Institute of Ferrous Metallurgy, the new heat treatments were investigated at IWT. At the Institute of Materials Science and Engineering, a new approach in high throughput fatigue testing methods (“Phybal”) was evaluated in these material conditions to discover the most promising combinations. The gear grades finally were tested as real gears at the Gear Research Centre while the most favorable bearing steels were tested as deep groove ball bearing inner rings at IWT. This paper will cover the investigations on 52100 bearing steel. At high loads, the new alloys showed equivalent lifetimes compared to industrial bearings. Yet the improved damage tolerance was revealed in testing conditions with lower loads (2,800 MPa Hertzian stress) with artificially damaged inner raceways. The best alloy and heat treatment combination of aluminum-alloyed 52100 steel achieved a 16 times longer life.
Divorced Eutectoid Transformation in the Spheroidization of Bearing Steels
Authors: Sherif Mohamed Y. , Huang Hanzheng
Published: December 2017

Using dilatometry, it was possible to follow the various phase transformations encountered while spheroidizing-annealing bearing steels. A steel with 0.67 wt% carbon has been considered in the present study, as an example, where the starting microstructure was tough-tempered martensite. In addition, the widely used bearing steel 100Cr6 was investigated as a reference. The aim of the work was to focus on the austenite transformation into divorced pearlite in an attempt to optimize currently employed spheroidizing-annealing heat treatment schedules.

Published: December 2017

A near-eutectoid lower-carbon vanadium-alloyed steel has been under consideration for bearing steel components where improved toughness, and therefore better micro-defect tolerance, is required. Due to the steel’s relatively lower concentration of carbon—that is, compared with a typical approximately 1 wt.% C through-hardened bearing steel, the hardenability was found to be higher. The steel design and heat treatment concepts have been investigated experimentally using, for example, dilatometry and transmission electron microscopy characterizing small-scale lab melts. The novel steel has been designed with a particular focus on continuous casting as a suitable process.
Microstructural Changes in Aerospace Bearing Steels under Accelerated Rolling Contact Fatigue Life Testing
Authors: Kirsch Mathew , Trivedi Hitesh
Published: December 2017

Operating in the extreme environment of a turbine engine, aerospace bearings must endure high thrust loads and very high rotational speeds. Subsurface fatigue damage is often observed as stressed zones, dark etching regions, light etching regions, and white etching regions. American Iron and Steel Institute (AISI) 52100 bearing steel is widely studied for microstructural changes and has been reported in the literature. Microstructural changes in a large test matrix of advanced materials for aerospace applications have not been studied. In this study, one through-hardened (VIM-VAR AISI M50) and four case-hardened materials (M50 NiL, M50 NiL Nitrided, Pyrowear® 675 High Temperature Temper, and Pyrowear® 675 Low Temperature Temper) were tested with silicon nitride balls under accelerated life conditions on a ball-on-rod rolling contact fatigue bench tester. Microstructural changes were characterized by light optical microscopy and scanning electron microscopy in radial and axial cross-section views. White etching cracks and white etching regions were observed in M50, M50-NiL, and M50-NiL (N) with shorter average fatigue lives as compared to either version of Pyrowear® 675.
Improvement of Fatigue Life Caused by Surface-Initiated Flaking in Rolling and Sliding Contact Condition by Modification of Subsurface Microstructure
Authors: Maruyama Takashi , Fujimatsu Takeshi , Tsunekage Norimasa
Published: December 2017

The most common failure in bearings under well-controlled lubricating conditions is internal-originated flaking. In contrast, surface-originated flaking, such as pitting, occurs in bearings and gears under rolling contact fatigue (RCF) with sliding contact. The friction force between steel parts in sliding contact causes surface damage. As a result, the parts’ flaking initiation is changed from the inside to the surface. Nowadays, due to the two following changes in global environmental issues, steel parts are expected to endure more serious conditions. (1) To suit the needs for reduction in size and weight, the allowable stress of steel parts tends to increase. (2) To improve power-transmission efficiency, viscosity of lubricant oil tends to decrease. In order to respond to these changes, clarification of the flaking mechanism is very important. However, under RCF with sliding contact, surface conditions such as texture and roughness change from moment to moment. These changes make it difficult to clarify the mechanism of surface-originated flaking. In the present work, the influence of subsurface microstructure of carburized steel on surface-originated flaking life was investigated under RCF with sliding contact. Chemical compositions of steel were varied to transform the subsurface microstructure after gas carburizing. Surface-originated flaking life was changed depending on the subsurface microstructure, which consists of intergranular oxide and incomplete quenching structure. Some RCF tests were interrupted and the wear of raceway and cross-sectional microstructure around the surface cracks was observed. The results indicated that the surface-originated flaking life can be improved by suppression of harmful surface cracks originating from intergranular oxides.
Behavioral Changes in Mice Lacking Interleukin-33

Published: December 2017

Interleukin (IL)-33 is a member of the IL-1 family of cytokines. IL-33 is expressed in nuclei and secreted as alarmin upon cellular damage to deliver a danger signal to the surrounding cells. Previous studies showed that IL-33 is expressed in the brain and that it is involved in neuroinflammatory and neurodegenerative processes in both humans and rodents. Nevertheless, the role of IL-33 in physiological brain function and behavior remains unclear. Here, we have investigated the behaviors of mice lacking IL-33 (Il33−/−mice). IL-33 is constitutively expressed throughout the adult mouse brain, mainly in oligodendrocyte-lineage cells and astrocytes. Notably,Il33−/−mice exhibited reduced anxiety-like behaviors in the elevated plus maze (EPM) and the open field test (OFT), as well as deficits in social novelty recognition, despite their intact sociability, in the three-chamber social interaction test. The immunoreactivity of c-Fos proteins, an indicator of neuronal activity, was altered in several brain regions implicated in anxiety-related behaviors, such as the medial prefrontal cortex (mPFC), amygdala, and piriform cortex (PCX), inIl33−/−mice after the EPM. Altered c-Fos immunoreactivity inIl33−/−mice was not correlated with IL-33 expression in wild-type (WT) mice nor was IL-33 expression affected by the EPM in WT mice. Thus, our study has revealed thatIl33−/−mice exhibit multiple behavioral deficits, such as reduced anxiety and impaired social recognition. Our findings also indicate that IL-33 may regulate the development and/or maturation of neuronal circuits, rather than control neuronal activities in adult brains.
Boosting of Thalamic D2 Dopaminergic Transmission: A Potential Strategy for Drug-Seeking Attenuation
Authors: Do-Monte Fabricio H. , Kirouac Gilbert J.
Published: December 2017

This commentary focuses on novel findings by Clark et al. (2017) published ineNeuro, which show that dopamine D2 receptors (D2Rs) in the paraventricular nucleus of the thalamus (PVT) are involved in cocaine sensitization. We extend the discussion on how their findings contribute to our understanding of the role of the PVT in drug seeking by providing new insight on the role of the PVT in the regulation of food-seeking and fear responses. We also consider the significance of the neuroanatomical findings reported by Clark et al., that the PVT is reciprocally connected with areas of the brain involved in addiction and discuss the implications associated with the source and type of dopaminergic fibers innervating this area of the thalamus.
Combinatorial Inputs to the Ventral Striatum from the Temporal Cortex, Frontal Cortex, and Amygdala: Implications for Segmenting the Striatum
Authors: Choi Eun Young , Ding Song-Lin , Haber Suzanne N.
Published: December 2017

The canonical striatal map, based predominantly on frontal corticostriatal projections, divides the striatum into ventromedial-limbic, central-association, and dorsolateral-motor territories. While this has been a useful heuristic, recent studies indicate that the striatum has a more complex topography when considering converging frontal and nonfrontal inputs from distributed cortical networks. The ventral striatum (VS) in particular is often ascribed a “limbic” role, but it receives diverse information, including motivation and emotion from deep brain structures, cognition from frontal cortex, and polysensory and mnemonic signals from temporal cortex. Using anatomical tract-tracing in 17 male adult monkeys (Macaca nemestrina,Macaca fascicularis,Macaca mulatta), we build upon this striatal map by systematically mapping inputs from frontal cortex, amygdala, temporal pole, and medial temporal cortex. We find that the VS contains heterogeneous subregions that become apparent when considering both the identities and strengths of inputs. We parcellated the VS into a ventromedial sector receiving motivation and emotion-related information from regions including area TG, ventromedial PFC, ACC, and amygdala; and a more functionally diverse dorsolateral sector that receives this information coupled to cognitive and sensorimotor information from dorsolateral PFC, ventrolateral PFC, premotor cortex, area TAr, and area TEr. Each sector was further parcellated into smaller regions that had different proportions of these inputs. Together, the striatum contains complex, selective input combinations, providing substrates for myriad associations. This VS parcellation provides a map that can guide and interpret functional interactions in healthy individuals and those with psychiatric disorders, and may be useful in targeting treatments for specific psychiatric conditions.

Remarks on the etymology of Old Turkic yutuz
Authors: Sağol Yüksekkaya Gülden
Published: December 2017

Language, which is the main carrier of culture, and culture are two things that complement each other. The language of an individual is shaped under the influence of the society and community the person lives in as a part of it. The feelings and mentality of people of former periods have left their imprint on and are reflected in the language. Bearing this in mind, in the present study an attempt is made to explain and elucidate the etymology of the Old Turkic word yutuz ‘wife, woman’.

Despite the problems presented by lexical errors in second language (L2) communication, most computer assisted language learning (CALL) programs tend to focus on the acquisition of grammar points rather than on the development of the L2 lexicon. In addition, CALL vocabulary tasks are typically limited in scope and mechanical in nature, covering mostly basic lexical meanings and ignoring many implications of language-related research that points out the need to focus on the layers of meanings associated with lexical items in various cultural contexts. This article brings together findings from research in various research fields related to Spanish SLA (e.g., cognitive psychology, psycholinguistics, and sociolinguistics) in order to propose 10 design features (DFs) of CALL software that would apply these insights to the creation of various types of computer-based lexical acquisition activities. As the authors propose these principles, they review several examples of Spanish CALL lexical materials in terms of their application of current theory (SLA and related fields) to practice (the design of the software activities to teach vocabulary). To conclude, the authors discuss logistical barriers that complicate and inhibit the application of theory and empirical research to practice in the creation of Spanish CALL lexical materials.
Task Design in Videoconferencing-supported Distance Language Learning
Authors: Wang Yuping
Published: December 2017

This article addresses a pervasive need in the area of videoconference-supported distance language learning: task design. On the basis of Chapelle's (2001) criteria for CALL task appropriateness, this article proposes a set of criteria for evaluating videoconferencing-based tasks which examine such aspects of a task as practicality, language-learning potential, learner fit, authenticity, and positive impact. These criteria were then tested with language learners who completed various tasks using a videoconferencing tool called NetMeeting. Upon examination of the findings in regard to each of these criteria, issues in videoconferencing task design and performance are recommended for further study.
Numerical investigation of railway transition zones stiffened with auxiliary rails
Authors: Esmaeili Morteza , Heydari-Noghabi Hamidreza , Kamali Mehdi
Published: December 2017

Culverts and bridges are the most common areas on railway lines where abrupt changes of track stiffness can occur. Using auxiliary rails in the transition zone is one option for gradually increasing track stiffness. The study reported in this paper investigated this issue by means of finite-element modelling. A ballasted track with a concrete culvert on the Tehran–Isfahan high-speed railway line in Iran was modelled and the effect of installing auxiliary rails in the transition zone was investigated. The ballasted track and its components – including railpads, ballast and subgrade – were modelled as a series of mass–spring–damper systems, while the sleepers and culvert were simulated using Euler–Bernoulli beam elements. The dynamic behaviour of the track and its components was investigated by simulating loads moving at different speeds. The results indicated there was a reduced variation in rail deflections, track accelerations and railpad forces, demonstrating that auxiliary rails improve the dynamic performance and behaviour of transition zones.

Edward Said, la periferia y el humanismo o tácticas para trascender el postmodernismo
Authors: Figueroa José Antonio
Published: December 2017

En este artículo se busca proponer una indagación en torno al valor del humanismo en la obra de Edward Said. Se intenta realizar esta indagación a través del recorrido por ciertas rutas intelectuales que nos llevan a situar a Said en las antí-podas del postmodernismo. Para esto se mostrará cómo en la obra de Said encontramos una paradoja intelectual y política que podría arrojar frutos insospechados en el diseño de agendas académicas y políticas en países sometidos a densas experiencias coloniales como sucede con los países latinoamericanos.
Jama, caleta y camello
Authors: Pachano Simón
Published: December 2017

Uno de los agujeros negros de la ciencia política latinoamericana se encuentra en el estudio de los que, parafraseando a Lechner, podrían considerarse como los patios interiores de los partidos políticos. La cantidad y calidad de los estudios de sistemas de partidos, de las condiciones de la competencia electoral o de la tensión entre liderazgos personalistas e instituciones, no se encuentra cuando se pretende caminar por ese lado oscuro de la vida de las organizaciones políticas. Por una serie de razones se ha privilegiado el análisis de la competencia y del desempeño público, mientras se ha relegado a un plano muy secundario la investigación de lo que sucede adentro de ellos. Un gran déficit de conocimiento de sus características intrínsecas y por lo tanto de su capacidad organizativa y de sus potencialidades, es el resultado final de este sesgo.
De empleada a ministra! : despatriarcalización en Bolivia
Authors: Díaz Carrasco Marianela Agar
Published: December 2017

Este artículo analiza el proceso de interpelación a los imaginarios de servilismo establecidos como horizontes de posibilidad para las mujeres indígenas aymaras y quechuas, a partir de la ocupación de cargos jerárquicos en los órganos del Estado Plurinacional de Bolivia. Espacios que han sido históricamente restringidos para las mujeres indígenas debido al colonialismo interno y a las relaciones de subalternización existentes. Se contextualiza dicho proceso en la historia reciente, desde el proceso constituyente que deviene en la propuesta de despatriarcalización, la misma que genera diversas, aunque aún iniciales, discusiones teóricas en torno al tema.
Proceso organizativo del campesinado en el sur de Manabí y desarrollo rural
Authors: Guerrero C. Fernando
Published: December 2017

Este artículo aborda el proceso organizativo del campesinado en el marco general del desarrollo rural de los últimos treinta años en la microregión del sur de Manabí, MSM. Se constata que a lo largo de las últimas décadas –del setenta en adelante– los campesinos de dicha microregión, a través de sus organizaciones de base y de segundo grado, han demostrado una gran capacidad de adaptación a los cambios económicos y, por otra parte, cierto margen de respuesta e incluso de resistencia ante los procesos de “intervención del desarrollo”. Las organizaciones campesinas manabitas, ante la crisis de la producción y exportación del café acudieron a la diversificación de las fincas, al cultivo de ciclo corto, a la pluriactividad y a la emigración, así como a la conformación de organizaciones e instituciones como un recurso, no solo de representación, sino también como instancias de mediación entre el campesinado y las entidades de desarrollo públicas y privadas.

O estándar galego nas novas xeracións: entre o afastamento e a necesidade
Authors: Iglesias Álvarez Ana , Álvarez García Xosé , Díaz Muñiz Salomé
Published: December 2017

Neste artigo abordamos a análise da percepción do estándar galego por parte das novas xeracións, en concreto, alumnado de cuarto da ESO, procedente de diferentes tipos de hábitat (rural, vilego e urbano). Na fase de produción dos datos recorremos á técnica cualitativa do grupo de discusión. Realizamos sete grupos formados por sete ou oito participantes cada un deles, de xeito que traballamos en total con 52 informantes. Estudamos en primeiro lugar como conciben o estándar e autoavalían a súa competencia nesta variedade, tanto a nivel oral como escrito. Ao descubrir que entenden o estándar, polo menos no caso do galego, como unha variedade estilística ou situacional, profundamos nesta cuestión no sentido da súa valoración sobre o uso: en que contextos consideran adecuado utilizar o estándar e en cales non e por que. Para finalizar, analizamos se as críticas tradicionais que recibía o estándar manteñen ou non a súa vixencia.
Por outras palavras e digamos: marcadores de reformulación?
Authors: Macário Lopes Ana Cristina , Carapinha Conceição
Published: December 2017

Este contributo ten como obxectivo dar continuidade ao estudo dos marcadores de reformulación en PEC (Lopes 2014). Deste modo, descríbese o funcionamento sintáctico e semántico-pragmático dos marcadores discursivos por outras palabras e digamos, a partir de datos empíricos recolhidos no CETEMPúblico e no subcorpus oral espontáneo do CRPC, e conclúese que, a pesar de que ambos poden ser incluídos no paradigma dos reformuladores, digamos non é un exemplar de todo prototípico, dada a súa especial produtividade como indicador de dúbida na reformuación do discurso e marcador de atenuación discursiva.
Influência do tempo máximo de mistura e transporte especificado pela ABNT NBR 7212:2012 na resistência a compressão de concretos usinados
Authors: Barboza Lucas Da Silva , Gonçalves Eliseu Cunha , Dos Santos Tarcila Malena Souza , Sartorti Artur Lenz
Published: December 2017

A ABNT NBR 7212:2012, estipula o tempo máximo para a entrega e lançamento total do concreto em 150 minutos; porém, na prática por vários fatores como logística, congestionamento, problemas com caminhão, entre outros, o tempo limite é extrapolado. Geralmente, por falta de conhecimento técnico, adiciona-se água ao concreto como forma de alterar sua consistência dando a trabalhabilidade desejada, a fim de facilitar o lançamento e obter adequado acabamento do concreto. Este artigo tem como objetivo principal avaliar, em situação real, a variação da consistência do concreto e a percentagem de perda de sua resistência à compressão, no decorrer de um período de 6 horas após o início da hidratação do cimento Portland, ocasionado pela adição de água para correção da fluidez perdida. Os resultados, como esperados, mostram uma redução na trabalhabilidade do concreto com o passar do tempo, obtendo-se, já nas 2 primeiras horas de mistura, um abatimento médio de 105 mm, ou seja, 11,54% inferior ao abatimento médio encontrado no tempo T(0) de 118,7 mm. A correção do abatimento do concreto através da adição de água, no tempo T(6), resultou no aumento do fator água/cimento ocasionando perda de 57,47% de resistência à compressão, quando comparada com as amostras do tempo T(0), aos 28 dias. As soluções oferecidas para este problema são: instruir os funcionários relacionados à concretagem; melhora da logística e utilização de aditivos, garantindo a resistência à compressão prevista na dosagem do concreto.
Análise do desempenho térmico, lumínico e de ventilação natural de projeto padrão de edifício escolar do FNDE de acordo com os requisitos de normas e referenciais nacionais e internacionais nas 8 zonas bioclimáticas brasileiras
Authors: Babick Cláudia Silva , Torres Maurício Carvalho Ayres
Published: December 2017

Buscando reduzir o déficit de vagas nas creches da rede pública, o Governo Federal brasileiro criou, em 2007, o programa Proinfância, o qual disponibilizou recursos para a implantação de escolas de educação infantil e quatro projetos padrão, que desde então vêm sendo construídos em todo o país. Levando em conta estudos que demonstram a ampla relação entre a qualidade das edificações com o desempenho na aprendizagem, este artigo tem o objetivo de verificar se o projeto Padrão Tipo-C, desenvolvido pelo FNDE, é adequado para a utilização nas 8 zonas bioclimáticas brasileiras no que se refere a iluminação, ventilação e conforto térmico. O projeto foi analisado e contrastado às exigências das normas e referenciais técnicos brasileiros e internacionais sobre os temas, verificando se possui as características necessárias para atingir o desempenho requerido em cada requisito. Foi constado que o projeto não contempla todas as variáveis de estratégias de projeto necessárias para um bom desempenho em todas as zonas bioclimáticas brasileiras, o que pode implicar em maior consumo energético para alcançar requisitos mínimos de conforto para os usuários.
La moda y los productos de lujo en los mercados online: una mirada desde la perspectiva del derecho marcario
Authors: Salas Brenda
Published: December 2017

La comercialización de la moda y de los productos de lujo tradicionalmente se ha hecho en grandes superficies, boutiques o en tiendas. Sin embargo, la moda quiere expandirse a los mercados online. Diferentes inquietudes surgen respecto de estos, a saber, la definición de la responsabilidad por las infracciones a los derechos marcarios y el rol de los sujetos que participan en la distribución online, es decir, del infractor directo y del prestador e-commerce. La industria de la moda y de los productos de lujo no es ajena a este cuestionamiento, es más, se trata de uno de los sectores que han sido afectados por la piratería y el contrabando en Internet. El propósito de este artículo es identificar la respuesta ofrecida en distintos regímenes jurídicos, como el estadounidense, el europeo y el colombiano.
