Produtos educacionais do Mestrado Profissional em Ensino da UTFPR – Londrina: estudo preliminar das contribuições
Authors: Freire Gabriel Gonçalves , Rocha Zenaide de Fatima Dante Correia , Guerrini Daniel 
Published: May 2018

A qualidade da educação escolarizada requer o engajamento dos profissionais nas escolas em um processo formativo contínuo em que o Mestrado Profissional em Ensino se apresenta como um possível percurso. Nessa perspectiva formativa, os produtos educacionais são apresentados
como elementos relevantes para a qualidade das práticas pedagógicas em que são inseridos e para o próprio processo formativo do pesquisador. O problema, diante disso, refere-se às contribuições que um produto educacional pode trazer para a qualidade da prática pedagógica.
Com base na problemática, o objetivo do estudo foi identificar quais contribuições os produtos educacionais do Mestrado Profissional em Ensino (PPGEN) oferecem para as práticas pedagógicas. Tratou-se de uma pesquisa qualitativa, descritiva, de caráter bibliográfico, na qual se contemplou quatorze produtos educacionais e dissertações de pós-graduação defendidas no ano de 2015. Verificou-se que as contribuições para as práticas pedagógicas relacionam-se à tipologia do produto educacional, à temática abordada em cada um, ao público-alvo e ao
processo formativo dos pesquisadores que elaboraram cada produto. Devem ser incentivados estudos dessa natureza que, além da abordagem sobre as contribuições pedagógicas, analisem o processo de divulgação dos produtos educacionais e a democratização do ensino a partir deles.

Quando uma professora de Matemática do CAP-UERJ resolve produzir escritas de si: autoformação?
Authors: Brião Gabriela Félix 
Published: May 2018

Este trabalho é um breve relato sobre uma pesquisa (auto)biográfica de uma professora de matemática em busca de compreensão de suas práticas e formação docentes. De forma a tentar descortinar práticas ora insubordinadas criativas, ora contraditórias, com suas próprias crenças sobre o que é a matemática, a autora tenta transportar o leitor para um lugar de reflexão, por vezes, desconfortável. De todo modo, é desta forma que a jornada se apresenta, em meio a diversos conceitos da Educação Matemática, mas também se aproximando da literatura. Como contribuição direta destes escritos podemos citar a produção de conhecimento ao
redimensionar saberes implícitos, sobre como um professor de matemática vê as suas práticas e formação, o catapultando para a visibilidade no que há de mais corriqueiro no seu dia a dia profissional, sua prática em sala de aula.

La función de Gobierno en la Constitución española, cuarenta años después
Authors: Porras Nadales Antonio 
Published: May 2018

Resumen:El modelo constitucional español expresa una apuesta por la gobernabilidad que nace del contexto histórico propio del parlamentarismo racionalizado y se fundamenta sobre un sistema electoral establecido desde 1977. Sin embargo tanto la configuración orgánica del ejecutivo como la puesta en práctica de la función de gobierno han tenido un desarrollo bastante limitado en la práctica, y algunas tareas centrales como la orientación estratégica, la programación de políticas públicas o la coordinación general del sistema se han reducido a puras inercias.Abstract:The Spanish constitutional model express a commitment to gobernability that is born from the historical context of «rationalized parlamentarism» and is based on an electoral system established since 1977.

La revocación de senadores de designación autonómica (la Ley valenciana 10/2016 y la STC 123/2017)
Authors: Navarro Marchante Vicente 
Published: May 2018

Resumen:La Comunidad Autónoma Valenciana aprobó a finales del pasado año la Ley 10/2016 que modificaba varios aspectos de la ley territorial que regulaba diferentes aspectos en torno a la designación de senadores en representación de la Comunidad Autónoma. La nueva norma introduce, de forma novedosa en nuestro derecho, la posibilidad de revocación del senador designado por el parlamento autonómico, además de establecer la obligatoriedad del senador de comparecencia ante la cámara designante como forma de rendición de cuentas. La posibilidad de revocación del senador por pérdida de confianza de la cámara autonómica planteaba dudas de constitucionalidad por, entre otros, posible vulneración de la prohibición de mandato imperativo de los miembros de las Cortes Generales, ya resueltas por la STC 123/2017. El presente artículo, al hilo del análisis de la norma valenciana y su encaje constitucional, reflexiona sobre la naturaleza del mandato representativo y la peculiar función de la cámara derepresentación territorial.Abstract:The Valencian Autonomous Community approved at the end of last year the Law 10/2016 that modified several aspects of the territorial law that regulated different aspects about the appointment of senators in representation of the Autonomous Community. The new norm introduces, in a novel way in our right, the possibility of revocation of the senator appointed by the autonomic parliament, in addition to establishing the mandatory of the senator of appearance in the designating chamber as a form of accountability. The possibility of revocation of the senator due to loss of confidence of the autonomous chamber raises doubts of constitutionality by, among others, possible violation of the prohibition of imperative mandate of the members of the Cortes Generales, already resolved by STC 123/2017. This article, along the lines of the analysis of the Valencian norm and its constitutional reserve, reflects over the nature of the representative mandate and the peculiar function of the chamber of territorial representation.

La ejecución de las resoluciones del Tribunal Constitucional. ¿Un cambio de modelo de justicia constitucional?
Authors: Álvarez Conde Enrique 
Published: May 2018

Resumen:La reforma, en 2015, de la LOTC ha supuesto importantes consecuencias jurídicas y políticas. En cuanto a las primeras se refiere, la reforma ha puesto en tela de juicio nuestro modelo de justicia constitucional así como la propia posición del Tribunal en relación con los demás poderes del Estado. Desde el punto de vista político, la reforma, aprobada precipitadamente y al final de la legislatura, esta concebida únicamente para resolver el problema soberanista catalán, situando en sede jurisdiccional decisiones políticas que nunca corresponden a un órgano de Justicia Constitucional. Como señaló la propia Comisión de Venecia, en su informe de marzo del 2017, y pese a haber sido declarada constitucional la reforma realizada, no es recomendable que estas competencias de ejecución sean atribuidas al Tribunal Constitucional.Abstract:The Spanish Constitutional Court Organization Act reform of 2015 has had significant legal and political repercussions. From a legal perspective, the reform has called into question both our constitutional justice model and the Court’s role in relation to other State powers. From a political point of view, the unwisely rush in adopting said reform at the end of the parliamentary term, was solely intended to resolve the Catalan sovereignty issue, thus placing political decisions at the hands of a Constitutional Court that should not be deciding on such matters. As pointed out by the Venice Commission itself, in its report of March 2017, and despite the reform´s constitutionality, attributing such enforcement powers to the Constitutional Court is not recommended. Summary:I. General remarks. II. Theoretical issues raised: A) The likely disruption of the Constitutional Justice model. B) The notion of Constitutional Review. C) Enforcement as a constituent element of the jurisdictional function. III. New measures for enforcing Constitutional Court decisions: A) The nature of the sentences. B) The default rules. C) The position of the Court in relation to the implementation of its decisions. D) The imposition of fines. E) Suspension of duties. F) Execution of alternative measures. G) Adoption of other necessary measures. IV. Implementation of the corresponding enforcement measures.
Topique et poétique du sublime. La leçon du laconisme quignardien
Authors: Declercq Gilles 
Published: May 2018

Une affinité stellaire lie Pascal Quignard à l’auteur du Traité du sublime. Est donc ici étudiée la topique commune au sublime longinien et quignardien (energeia du transport pathétique ; court-circuit de la raison par le raptus esthétique ; emprise impérieuse du sensible sans logos). Ce sublime prend chez Quignard la forme verbale du laconisme, forme-sens qui confère au style le statut d’une arme de survie qui permet au lecteur, à l’écrivain et au penseur de tenir face aux forces prédatrices sous-jacentes au langage. Cette poïétique du style soustractif propre à la sentence foudroyante s’arrime au versant narratif de l’oeuvre par la ligature discrète de l’argumentation paradigmatique où l’assertion, thèse spéculative, trouve son argument dans l’essor même du récit.
Pascal Quignard : du monument à la ruine, de la ruine au vivant
Authors: Vuong Léa 
Published: May 2018

Si la ruine est un motif omniprésent chez Pascal Quignard, l’auteur semble aussi poursuivre une ambition monumentale, celle du Dernier royaume, commencée en 2002 et qu’il poursuit toujours aujourd’hui. Cet article explore l’hésitation entre l’élaboration d’un monument littéraire et l’esthétique des ruines qui irrigue les textes de Quignard. Il donne une place privilégiée à des ouvrages récents, comme Sur l’idée d’une communauté de solitaires (2015), et aux dialogues avec d’autres arts tels que la musique, la danse et l’art visuel. Cette étude s’intéresse également aux fragments de textes et aux figures obscures, parfois dissimulées, qui nourrissent et influencent l’oeuvre : Roland Barthes, Walter Benjamin, mais aussi les artistes Carlotta Ikeda et Pierre Skira. Cet article montre d’abord les ruines comme des supports solides qui soutiennent la construction de monuments littéraires où Quignard commémore le souvenir d’êtres disparus. Puis, en s’appuyant sur la notion de « ruinophilie » développée par Svetlana Boym, cette étude expose la porosité des ruines quignardiennes, et s’intéresse à la manière dont elles laissent filtrer d’autres motifs, celui de la nature et du corps, à travers lesquels l’écrivain élabore, dans son écriture, de nouvelles manières de vivre dans le temps et dans l’espace.
Robust control and data‐driven tuning of a hybrid integrator‐gain system with applications to wafer scanners
Authors: Heertjes M.F. , Irigoyen Perdiguero N. , Deenen D.A. 
Published: May 2018

SummaryA hybrid integrator‐gain system is discussed that aims for improved low‐frequency disturbance rejection, while, at the same time, does not deteriorate overshoot and settling times when compared with a linear integrator. The hybrid integrator has similar phase advantages as the well‐known Clegg integrator but without inducing the discontinuous behavior resulting from resetting system state values. Optimal tuning of the controller parameters of the hybrid integrator is strongly influenced by machine‐specific properties and therefore favors a data‐driven optimization approach. However, as a time‐domain optimization algorithm can easily lead to nonrobust solutions in the sense of large peaking of the closed‐loop frequency response functions, frequency‐domain robustness constraints will be imposed. By means of an adaptive weighting filter design, the parameter updates are penalized upon violation of said robustness constraints. Posed in an unconstrained problem formulation, this is subsequently solved by applying a Gauss‐Newton–based parameter update scheme. Closed‐loop stability of the linear time‐invariant plant and controller in feedback connection with a hybrid integrator‐gain system element follows from a circle‐criterion‐like analysis, which is based on evaluating (measured) frequency response data. Measurement results obtained from an industrial wafer scanner demonstrate the effectiveness of the approach.
Low‐Bandgap Polymers for High‐Performance Photodiodes with Maximal EQE near 1200 nm and Broad Spectral Response from 300 to 1700 nm
Authors: Han Jinfeng , Yang Dezhi , Ma Dongge , Qiao Wenqiang , Wang Zhi Yuan 
Published: May 2018

AbstractPolymer photodiodes with broad spectral response above 1500 nm can be used for imaging in the near‐infrared window of the atmosphere. Three low‐bandgap polymers based on 3,6‐dithiophen‐2‐yl‐2,5‐dihydropyrrolo[3,4‐c]pyrrole‐1,4‐dione (DPP), [1,2,5]thiadiazolo[3,4‐g]quinoxaline (TQ), benzobisthiadiazole (BBT), and dithienopyrrole (DTP) are designed and synthesized. No‐gain and gain polymer photodiodes with polymers:PC71BM as active layer materials and with aluminum doped ZnO nanoparticles:2,9‐bis(3‐(dimethylamino)propyl)anthra[2,1,9‐def:6,5,10‐d′e′f′]diisoquinoline‐1,3,8,10(2H,9H)‐tetraone (AZO:PDIN), MoO3, and 2,9‐dimethyl‐4,7‐diphenyl‐1,10‐phenanthroline (BCP) as interlayer materials are prepared. No‐gain photodiodes based on polymer P1 exhibit the external quantum efficiency (EQE) of 7.8% at 1200 nm, which is among the best values of polymer photodiodes known to date. Gain photodiodes based on P1 and P3 also exhibit a maximal EQE near 1200 nm. In addition, gain photodiodes based on P1 have a specific detectivity over 1013 Jones in 300–1360 nm and spectral response in the region of 300–1700 nm.
Single Plasmonic Oligomer Chiral Spectroscopy

Published: May 2018

AbstractChirality plays a crucial role in our everyday lives. Many biomolecules are handed and the associated biological processes rely on their handedness. Thus, chirality is investigated intensely, also because of the fundamental and inherent interest in the concept of chirality. However, virtually all studies are performed on large ensembles of chiral objects, which obstructs the contribution of the individual particle. Hence, it is highly desirable to study individual chiral objects. Here, it is shown how to measure chiroptical spectra in the visible spectral range of left‐ and right‐handed C4 symmetric single plasmonic nanoantenna ensembles, which are termed oligomers. The two‐layered oligomers are fabricated by top‐down electron beam lithography to offer a high degree of structural control. Dark‐field scattering spectroscopy as well as correlative scanning electron microscopy are utilized to study the influence of structural arrangement and individual shape on the optical properties of a single plasmonic oligomer. Even minute structural differences, which cannot be resolved in scanning electron microscopy, manifest themselves in clear differences in the chiroptical response. The results play an important role for further investigations and optimizations in design, fabrication, and measurements of single plasmonic enantiomers but also on the way toward single chiral object sensing.

Published: May 2018

AbstractStilbenes are important and useful structural moieties, but methods for their preparation typically possess numerous inefficiencies. Presented here is a methodology for the two‐step, one pot preparation of unsymmetrical stilbenes via sequential Heck reactions. The first Heck reaction with ethylene gas was analysed as a function of temperature and pressure for electronically differentiated naphthyl bromides and model‐aided reaction optimization was utilized to define the system. In addition, reactNMR was utilized to determine ethylene solubility in common organic solvents useful for Heck reactions. Finally, an optimized sequential Heck reaction process was developed and applied to a range of substrates allowing for efficient preparation of unsymmetrical stilbenes, including the natural antioxidant, pterostilbene.magnified image
Neue Methoden und Designprinzipien für zellgängige Peptide
Authors: Peraro Leila , Kritzer Joshua A. 
Published: May 2018

AbstractBiomoleküle, wie Antikörper, Proteine und Peptide, sind wichtige Werkzeuge in der chemischen Biologie und Ansatzpunkte für die Wirkstoffentwicklung. Sie wurden erfolgreich verwendet, um eine Reihe von extrazellulären Proteinen zu inhibieren, allerdings stellt die Interaktion mit intrazellulären Proteinen eine weit größere Herausforderung dar. In dieser Aufsatz diskutieren wir unterschiedliche chemische Ansätze, die zu zellgängigen Peptiden geführt haben, und identifizieren drei eigenständige Vorgehensweisen: die Maskierung von Rückgratamiden, die Strukturierung von Guanidingruppen und die amphipathische Strukturierung. Wir fassen zusammen, wie anhand großer Datensätze, die in steigendem Maße entstehen, spezifischere Designprinzipien für jede dieser Strategien abgeleitet werden können. Wir beschreiben außerdem Vor‐ und Nachteile gängiger Methoden zur Quantifizierung der Zellpenetration. Abschließend geben wir eine Übersicht über die vielversprechendsten Ansätze für die Anwendung dieser neuen Methoden und Designprinzipien zur Optimierung der zytosolischen Penetration eines bioaktiven Peptids.
Dipole Effects on Electron Transfer are Enormous

AbstractMolecular dipoles present important, but underutilized, methods for guiding electron transfer (ET) processes. While dipoles generate fields of Gigavolts per meter in their vicinity, reported differences between rates of ET along versus against dipoles are often small or undetectable. Herein we show unprecedentedly large dipole effects on ET. Depending on their orientation, dipoles either ensure picosecond ET, or turn ET completely off. Furthermore, favorable dipole orientation makes ET possible even in lipophilic medium, which appears counterintuitive for non‐charged donor–acceptor systems. Our analysis reveals that dipoles can substantially alter the ET driving force for low solvent polarity, which accounts for these unique trends. This discovery opens doors for guiding forward ET processes while suppressing undesired backward electron transduction, which is one of the holy grails of photophysics and energy science.
