Authors: Hernández de la Torre Elena , Medina Herasme Raulina 
Published: January 2019

Este estudio pretende indagar en los dilemas y controversias de un centro de secundaria que influyen en el desarrollo de procesos de planificación y gestión a partir de un trabajo colaborativo que propicie el progreso y la mejora. Para ello se han utilizado técnicas biográfico-narrativas en tres momentos: entrevistas individuales y grupales y observaciones de reuniones, grabaciones de sesiones de un Programa de Formación y discusión de temas a debate y entrevistas individuales finales a miembros observadores inmersos en el proceso del estudio. En este estudio han participado profesores, alumnos, orientador, equipo directivo, coordinador del grupo de trabajo así como alumno en prácticas durante un curso escolar. Los resultados muestran datos respecto a una variedad de conflictos y dilemas de índole contextual y estratégica que impiden el establecimiento de un trabajo colaborativo en el centro que potencie una filosofía de trabajo basada en la equidad y el aprendizaje para todos.
The aim of this study is to analyze the issues and controversies that arise in a secondary school that affect the development of planning and management procedures based on cooperation, aiming to progress and improvement. The methodology of the study consists of biographical and narrative techniques applied in three phases: individual and group interviews, analysis of meetings, recordings from sessions of a Training Program and discussions of several topics; and final individual interviews to monitoring members involved in the analysis. The study includes the participation of teachers, students, the school counselor, the executive board, the coordinator of the working group and a student who was working in the school as part of an internship during the academic year. The results show several issues and conflicts of a contextual and strategic nature that prevent the development of cooperative work with a philosophy based on equity and general development.

Authors: Ibarra Saiz María Soledad , Rodríguez Gómez Gregorio 
Published: January 2019

El uso de modalidades participativas de evaluación es una de las principales líneas de investigación e innovación en la educación superior. Esta investigación se planteó con el objetivo de analizar la percepción que el profesorado y los estudiantes universitarios manifiestan respecto a la utilización de la autoevaluación, evaluación entre iguales y coevaluación. Para ello se diseñaron dos cuestionarios, profesorado y estudiantes, a través de los cuales se recogieron las percepciones de 3.459 estudiantes y 424 profesores en siete universidades, iberoamericanas y españolas, pertenecientes a seis países. Como conclusión se evidencia, en primer lugar, un acuerdo sobre el escaso uso de modalidades participativas de evaluación en las universidades y, en segundo lugar, se resalta la necesidad de establecer procesos formativos, tanto para profesorado como para estudiantes, que incidan en el conocimiento y puesta en práctica de dichas modalidades con el fin de mejorar en los estudiantes un aprendizaje autónomo y estratégico.
The use of participatory assessment methods is one of the main lines of research and innovation in higher education. The aim of this research was to analyse the perception of both university teaching staff and students regarding the use of self-assessment, peer-assessment and co-assessment. Two questionnaires were designed for this purpose, one for the lecturers and one for the students, by means of which the perceptions of 3,459 students and 424 lecturers of seven Latin American and Spanish universities from six different countries were measured. In conclusion, there is, in the first place, evidence of an agreement regarding the scant use of participatory assessment methods in universities and, secondly, there is an emphasis on the need to establish training processes for both teaching staff and students in order to disseminate information concerning these methods and put them into practice in order to improve students´ independent and strategic learning.
Estados emocionales contrapuestos como predictores del rendimiento académico en secundaria
Authors: Pulido Acosta Federico , Herrera Clavero Francisco 
Published: January 2019

Este trabajo tiene como objetivo fundamental analizar los predictores de Ansiedad, Felicidad y Rendimiento Académico, considerando la edad, género, cultura y estrato socioeconómico, así como contemplar las relaciones que se pudieran dar entre las variables, para una población adolescente multicultural. Para ello, se ha contado con 811 participantes, de seis centros en los que se imparte formación perteneciente a la Etapa Secundaria. Considerando la cultura, el grupo mayoritario es el de participantes pertenecientes a la cultura-religión musulmana. Estos constituyen el 71.6% de la muestra, mientras que el 28.4% de la misma pertenecía a la culturareligión cristiana, siendo el 46.1% varones y el resto de la muestra (53.9%) mujeres. Como instrumentos de evaluación se han empleado el Inventario de Ansiedad Estado-Rasgo para Niños (STAIC, Spielberger, 2001), un cuestionario elaborado para evaluar la Felicidad junto con las calificaciones de los estudiantes. Los resultados reflejan que los predictores de la Ansiedad son la Edad y el Género. Para la Felicidad aparecen todas las variables sociodemográficas: Edad, Cultura, Estatus y Género. Se ha halló una fuerte relación inversa entre Ansiedad y Felicidad, actuando cada una como principal predictora de la otra. En Rendimiento Académico los predictores son el estatus, la cultura/religión y la edad. No se ha halló relación estadísticamente significativa entre Ansiedad y Rendimiento Académico, pero sí en el caso de la Felicidad.
This work has as main objective to analyze the predictors of Anxiety, Happiness and Academic Achievement, according to age, gender, culture and socioeconomic stratum as well as the relationships that could be given between all the variables, for a multicultural adolescent sample. To make it possible we focused on 811 participants from six educational centre; 71.6% of the total were Muslims and 28.4% belonged to the Christian religion, 46.1% were male and 53.9% female. The techniques used in this survey were the State-Trait Anxiety Inventory for Children (STAIC, Spielberger, 2001), a Happiness questionnaire, as well as the students’ grades. The results reflect that the predictors of Anxiety are Age and Gender. For Happiness, all the sociodemographics variables act as predictors: They are Age, Culture, Socioeconomic stratum and Gender. We found a strong and inverse relationship between Anxiety and Happiness. Each one act as the main predictor of the other. Academic Achievement predictors’ are the sociodemographic factors of status, culture and age. There is no statistically significant relationship between Anxiety and Academic Achievement, but we found it between Academic Achievement and Happiness.

Gernikaren itzalpean: Propaganda, Appropriation, and Depoliticisation of Basque Art Music
Authors: Besada José L. , Zubizarreta Ainara 
Published: January 2019

The Bombing of Guernica stands as the best-known war crime during the Spanish Civil War. The town symbolically representing the Basque essences was destroyed by a German-Italian air raid lasting over three hours, and almost two hundred people were killed. Unfortunately, this abominable event remains contentious among disparate political factions, sometimes upholding its memory by means of tailor-made interpretations.As music often performs a political role within conflicts, particularly those involving violence, it is not surprising that the Bombing of Guernica has inspired several compositions of art music. Among them, we study three works by Basque composers, namely Pablo Sorozábal, Francisco Escudero, and Ramon Lazkano. Each case study respectively stands, politically speaking, as a propagandistic event, a musical appropriation, and a collateral depoliticization of the vivid memories around the war crime.
« C’est devant YHWH que j’ai dansé »
Authors: Bellavance Éric 
Published: January 2019

Le comportement du roi David « devant YHWH », alors que l’arche de Dieu est transportée vers Jérusalem, dans un premier temps, puis dans Jérusalem, dans un deuxième temps, a fait couler beaucoup d’encre. De quelle nature est la danse qui y est décrite ? Pourquoi le roi agit-il de la sorte ? Et pourquoi sa femme Mikal, la fille de l’ancien roi Saül, est-elle choquée au point de le mépriser et de lui reprocher de s’être comporté comme un homme sans valeur ? Nous sommes d’avis que la femme du roi réagit négativement parce que David a eu une conduite qui s’apparente à celle d’un prophète extatique. L’hypothèse que nous avançons pour expliquer pourquoi David adopte une attitude semblable aux prophètes extatiques est inédite : le roi danse en présence non seulement de l’arche, mais d’une représentation de YHWH, possiblement sous forme de statue.
Une théologie de l’altérité : Michel de Certeau
Authors: Hervieux Lucie 
Published: January 2019

La question de l’altérité chez Michel de Certeau est au coeur de sa (dé)-marche théologique et noue inséparablement la question d’un sujet en quête de son désir et en ce qu’il se reconnaît comme manque à être. Quelques repères nous permettent d’étayer l’état de la question. Il semble que pour Certeau, la théologie, s’il en est une, se fait autrement. Depuis la modernité, quelque chose s’est rompu, le « dire » et le « faire » théologiques ne font plus consensus, ni sur les pavés des Églises, ni dans l’ordre des discours relatif à l’éveil des sciences humaines. Un socle s’est rompu. La rupture même fait office de lieu théologique, elle porte une coupure épistémologique : le travail théologique ne peut en aucun temps être fixé une fois pour toutes et figé dans des énoncés évidés de leur fondement, c’est-à-dire qui évacuent l’expérience même d’une rencontre de l’autre et de l’Autre. Il ne s’agit pas pour Michel de Certeau de poser un savoir sur Dieu ni de lui imposer un lieu mais de reconnaître l’(in)-appropriable d’un « non-lieu ». L’acte théologique pose désormais l’acte d’un sujet qui se met en mouvement, entamant une marche incessante, en travail de désir d’autre et en la rencontre de l’Autre. Le discours théologique porte le produit langagier de cette rencontre dans son (im)-possibilité d’en tenir lieu. La théologie devient ainsi elle-même acte d’énonciation.
Naftas produktu tranzīta stacijas “Ilūkste” teritorijas reālo sanācijas rezultātu salīdzinājums ar 1997. gada datorprognozi

Published: January 2019

Naftas produktu tranzīta stacija “Ilūkste” (turpmāk TS) nodrošina naftas produkta (turpmāk NP) dīzeļdegvielas plūsmu cauruļvadā no Baltkrievijas līdz Ventspilij. No 1970. gada līdz 1996. gadam TS veica arī NP iepildīšanu dzelzceļa cisternās. Tad notika NP noplūdes zem un pie dzelzceļa estakādes. Izveidojās pazemes ūdens piesārņojums ar NP, kas kā peldošs slānis (turpmāk NPPS) sasniedza Ilūkstes upes stāvo krastu. Lai novērstu NP iekļūšanu upē, te tika izrakts NP savākšanas dīķis, no kura varēja aizvākt NP. Piesārņotās teritorijas sanācija sākās 1996. gadā, un tā turpinās arī šobrīd. Kā īpašnieks šos darbus finansē un uzrauga SIA “LatRosTrans”. Kopš 2000. gada sanācijas darbus veic a/s “VentEko”. Šobrīd, pateicoties abu organizāciju sekmīgai ilgstošai sadarbībai un efektīvu NP savākšanas ierīču izmantošanai, piesārņotajā teritorijā praktiski nav NPPS. Diemžēl vēl ilgu laiku piesārņojumu, šķīstot ūdenī, radīs nekustīgā NP daļa gruntī. Rīgas Tehniskās universitātes (RTU) zinātnieki 1997. gadā izveidoja piesārņotās teritorijas hidroģeoloģisko modeli. Izmantojot šo modeli un programmatūru “ARMOS”, izdevās atrast galvenās NP noplūdes avotu. Modelēšana prognozēja, ka pašnotecē 25 gadu laikā NP var ieplūst savākšanas dīķī. RTU 2018. gadā novērtēja sanācijas rezultātus un konstatēja, ka tie visumā atbilst 1997. gada prognozei. Galvenās atšķirības skaidrojamas ar atkārtotām NP noplūdēm. Pieredze, kas iegūta TS “Ilūkste” teritorijas sanācijas gaitā, apstiprina modelēšanas metožu izmantošanas lietderību, uzsākot vides atveseļošanas pasākumu īstenošanu.

The Ilukste oil transit station pipelines ensure the flow of diesel fuel from Belarus to the town Ventspils in Latvia. In 1970–1996, the station also filled fuel (oil) in railway tanks, which resulted in oil leakages. Due to this, the groundwater under the railway terminal routes was contaminated. The groundwater flow enters the nearby Ilukste river. Fortunately, oil discharged over the ground from a steep bank before the river. To prevent the oil inflow into the river, a special pond was dug for its intercepting. Later, in order to divert the oil discharge underground, the horizontal drain for catching oil was installed before the pond.In 1996, remediation of the oil-contaminated station area started, which is followed up until now. The work was supervised and financed by the station owner “LatRosTrans” Ltd. Since 2000, the site sanitation was performed by the company “VentEko”.
PEDAGOGIA HISTÓRICO-CRÍTICA E PSICOLOGIA HISTÓRICO CULTURAL: INFERÊNCIAS PARA A FORMAÇÃO E O TRABALHO DE PROFESSORES

<div class="column"><p><span style="font-size: 11.000000pt; font-family: 'Garamond';">Este artigo apresenta a pedagogia histórico crítica e a psicologia histórico cultural, ensaia, ainda, fazer inferências para a formação de professores no Brasil. Para tanto, buscou-se a fundamentação teórica em autores como Dermeval Saviani, Newton Duarte, Vigotski, Leontiev, Lígia Márcia Martins, Marilda Facci, Marta Sforni. A pedagogia histórico crítica postula que o ato educativo caracteriza-se pela intencionalidade, tendo como objetivo a apropriação do conhecimento sistematizado pelo aluno. Nesse mesmo sentido, a psicologia histórico cultural compreende que a aprendizagem dos conhecimentos escolares são fundamentais para o desenvolvimento das funções psicológicas superiores. O bom ensino nessa perspectiva é aquele que promove o desenvolvimento do indivíduo que é sempre um desenvolvimento social e histórico. Estas abordagens fazem o enfrentamento e a superação das pedagogias do aprender a aprender que encontram seus fundamentos no construtivismo e que apregoam que mais importante do que ensinar ou aprender é levar o aluno a encontrar caminhos para o aprender a aprender. O trabalho do professor, segundo essas pedagogias, seria o de um facilitador da aprendizagem, o que tem levado a um esvaziamento de sua função acarretando sérias consequências para o processo do ensino aprendizagem dos alunos em sala de aula. Finalmente, este artigo aponta segundo a perspectiva marxista a defesa da formação omnilateral dos professores como elemento imprescindível para o avanço rumo à consolidação de um ensino público de qualidade.</span><span style="font-family: Garamond; font-size: 11pt;"> </span></p></div>
Micellar‐Mediated Block Copolymer Ordering Dynamics Revealed by In Situ Grazing Incidence Small‐Angle X‐Ray Scattering during Spin Coating
Authors: Fleury Guillaume , Hermida‐Merino Daniel , Jingjin Dong , Aissou Karim , Bytchkov Aleksei , Portale Giuseppe 
Published: January 2019

AbstractSpin coating is one of the most versatile methods to generate nanostructured block copolymer (BCP) thin films which are highly desired for many applications such as nanolithography or organic electronics. The self‐assembly pathways through phase separation, both in solvent and in bulk, strongly influence the final BCP structure obtained after spin coating. As a demonstration, the formation of highly ordered in‐plane lamellae is elucidated herein by using in situ grazing incidence small‐angle X‐ray scattering. A key step in this complex fast organization process is the formation of intermediate micellar phases triggered by solvent affinity toward one of the block. Indeed, directional coalescence of a short‐lived intermediate hexagonal structure of cylindrical micelles enables the development of a final highly ordered lamellar structure, predominantly oriented parallel to the substrate surface. These results suggest that the existence of such transient micellar phases is a crucial process in order to produce highly ordered structures with a specific orientation directly after the BCP thin film deposition; and should be the focus of further optimization for the directed self‐assembly and, more generally, in the bottom‐up nanostructure fabrication.
Tumor‐Specific Drug Release and Reactive Oxygen Species Generation for Cancer Chemo/Chemodynamic Combination Therapy

AbstractThe combination of chemotherapeutic drugs and reactive oxygen species (ROS) is a promising strategy to achieve improved anticancer effect. Herein, a nanomedicine (LaCIONPs) that can achieve tumor‐specific chemotherapeutic drug release and ROS generation is developed for cancer chemo/chemodynamic combination therapy. The LaCIONPs are constructed by encapsulation of iron oxide nanoparticles (IONPs) and β‐lapachone (La) in nanostructure assembled by hydrogen peroxide (H2O2)‐responsive polyprodrug and pH‐responsive polymer. Through the enhanced permeability and retention effect, the nanosized LaCIONPs can accumulate in tumor tissue. After the LaCIONPs are internalized by tumor cells, the structure of LaCIONPs is disintegrated in acidic intracellular environment, leading to rapid release of La and iron ions. Then the released La generates massive H2O2 through tumor specific catalysis. On the one hand, H2O2 further reacts with iron ions to produce highly toxic hydroxyl radicals for chemodynamic therapy. On the other hand, H2O2 also activates the release of camptothecin from the polyprodrug for chemotherapy. The potent antitumor effect of the LaCIONPs is demonstrated by both in vitro and in vivo results. Therefore, the LaCIONP is a promising nanomedicine for tumor‐specific chemo/chemodynamic combination therapy.
New Floating Gate Memory with Excellent Retention Characteristics

Published: January 2019

AbstractIn current flash memory, there is an inevitable tradeoff between the operation voltage and the retention time due to the incorporation of very thin tunneling layer in the device structure. In this work, a new type of robust floating gate nonvolatile memory based on 2D materials is introduced to reduce the operation voltage and promote the data retention time. By taking the advantage of a dual‐gate structure, as‐fabricated devices exhibit excellent performance with low operation voltage (as low as 5 V even the tunneling layer t
BN ≥ 10 nm), long retention time (on/off ratio with negligible degeneration over 105 s), and ultralow off‐leakage current (10−13 A, which is very attractive for ultralow‐power applications). Charges trapped in the top gate originated from the capacitive coupling between the back and top gates are found to be responsible for the nonvolatile behavior. The new charge trapping mechanism, which is distinguished from that in the conventional single‐gate memory devices, enables charge tunneling through a thicker tunneling layer at a low operation voltage. The achieved MoS2 nonvolatile memory with outstanding performances has great potentials for future information storage.
Cellulose Nanopaper with Monolithically Integrated Conductive Micropatterns

Published: January 2019

AbstractThis work presents a route to fabricate micropatterned conductive structures where the conductors are monolithically integrated with nanocellulose‐based paper. To fabricate conductive features, microstructures are patterned on filter papers using wax‐printing, followed by vacuum filtration of carbon nanotubes (CNTs) or silver nanowires (AgNWs) dispersed in aqueous cellulose nanofibrils (CNFs). These patterns are then laminated onto a pure CNF substrate (both in gel‐state) and dried to form cellulose nanopapers with integrated conductive micropatterns. Resolutions of the conductive features are shown down to 400 µm wide, 250 nm thick, and with conductivity values of 115 ± 5 S cm−1 for the CNF–CNT and 3770 ± 230 S cm−1 for the CNF–AgNW micropatterns. The nanopaper and the conductive patterns both constitute random fibrous networks, and they display similar ductility and swelling behavior in water. Thus, the integrated conductive micropatterns can withstand folding, as well as wetting cycles. This stability of the micropatterns makes them useful in various devices based on nanocellulose substrates. As an example, an electroanalytical nanopaper device that operates in wet conditions is demonstrated.
Silicosis prevalence and incidence among Medicare beneficiaries
Authors: Casey Megan L. , Mazurek Jacek M. 
Published: January 2019

IntroductionExisting epidemiologic information on silicosis relies on mortality data.MethodsWe analyzed health insurance claims and enrollment information from 49 923 987 fee‐for‐service (FFS) Medicare beneficiaries aged ≥65 from 1999 to 2014. Three different definitions were developed to identify silicosis cases and results are presented as ranges of values for the three definitions.ResultsAmong FFS beneficiaries, 10 026‐19 696 fit the silicosis case definitions (16‐year prevalence: 20.1‐39.5 per 100 000) with the highest prevalence among North American Natives (87.2‐213.6 per 100 000) and those in New Mexico (83.9‐203.4 per 100 000). The annual average prevalence had a significant (P < 0.05) 2‐5% annual decline from 2005 to 2014. The average annual number of incident cases had a significant 3‐16% annual decline from 2007 to 2014.ConclusionsSilicosis is a prevalent disease among Medicare beneficiaries aged ≥65, with variation across the country. Morbidity data from health insurance claims can provide a more complete picture of silicosis burden.
