ORIENTATIONS D’ACCULTURATION DES QUÉBÉCOIS FRANCOPHONES À L’ÉGARD DES ITALIENS « VALORISÉS » ET DES MAFIEUX « DÉVALORISÉS »
Authors: Bourhis Richard Y. , Bosset David-Alexandre , Sioufi Rana 
Published: May 2018

Cette étude porte sur les orientations d’acculturation des Québécois francophones à l’égard des immigrants italiens « valorisés » et des immigrants mafieux « dévalorisés ». Un groupe d’étudiants québécois francophones (N = 217) a complété l’Échelle d’Acculturation de la Communauté d’Accueil (ÉACA) envers ces deux groupes cibles. Les résultats ont démontré que les répondants endossaient l’intégrationnisme, l’intégrationnisme de transformation, l’individualisme et le ségrégationnisme davantage envers les Italiens qu’envers les mafieux. En revanche, ils endossaient davantage l’assimilationnisme et l’exclusionnisme envers les mafieux qu’envers les Italiens, soutenant ainsi l’hypothèse que les Québécois francophones distinguent bien les Italiens « valorisés » des Italiens mafieux « dévalorisés » plutôt que de faire l’amalgame de ces deux groupes.
Le traitement et la diffusion du fonds Armand-Frappier (ou comment être opportuniste en huit leçons)
Authors: CARTIER FRANÇOIS 
Published: May 2018

Cet article nous relate les différentes étapes qui ont mené à la diffusion du Fonds Armand-Frappier. Ce fonds, déposé aux archives de l’Institut national de la recherche scientifique (INRS, une constituante du réseau de l’Université du Québec), illustre le parcours de cet homme qui eut une influence importante sur l’évolution des sciences au Québec. C’est le 25e anniversaire du décès du Dr Frappier qui a fourni le prétexte à ce projet de diffusion qui a finalement compris une exposition virtuelle et un programme de conférence. Pour arriver à leurs fins, l’équipe du service des archives de l’INRS a fait preuve de créativité et d’opportunisme afin d’aller chercher ressources et financement. Le projet a demandé dans un premier temps un nouveau traitement du fonds et a fait surgir de nombreuses questions quant au passage d’un format de description à un autre ainsi que sur les outils technologiques à utiliser.
L’auteur aura retenu huit leçons au cours de ce projet. Il nous les livre ici par la description de sa mise en oeuvre. Ces leçons concernent, entre autres, la capacité de vendre notre idée, celle de saisir les opportunités et la nécessité de bien choisir ses collaborateurs et partenaires. Il revient également sur certains éléments de gestion, tels que l’évaluation du temps requis et l’utilité du plan B. Il nous incite finalement à réaliser la richesse de nos fonds et de l’intérêt qu’ils suscitent chez les jeunes. Cet article nous démontre qu’avec de l’initiative et la maximisation des programmes à notre disposition, il est possible de réaliser des projets qui deviennent des réussites.
Les perceptions d’enseignants du primaire et le programme « Éthique et culture religieuse » : une analyse qualitative
Authors: Duclos Anne-Marie , Poellhuber Bruno 
Published: May 2018

L’implantation du programme de formationÉthique et culture religieuse(Ministère de l’Éducation, du Loisir et du Sport, 2008) entraine un « changement profond » au regard de notre système d’enseignement (Conseil supérieur de l’éducation, 2008). Les perceptions des agents d’implantation par rapport à une innovation éducative peuvent affecter non seulement sa mise en oeuvre, mais ses résultats (Fullan, 2007). Afin de mieux comprendre les perceptions des enseignants du primaire face au programme d’ÉCR, une entrevue exploratoire semi-dirigée a permis d’explorer les perceptions des répondants par rapport au programme et à sa mise en oeuvre. Les résultats obtenus des thèmes émergents sont plutôt négatifs, et ce, peu importe le niveau d’expertise des enseignants par rapport à l’utilisation du programme.

The new species is characterized by: SVL 11.7–14.6 mm in males, 14.0–16.7 mm in females; body slender; fingertips knobbed, with a central groove; hindlimbs short; abdominal fold complete; arytenoid cartilages wide; prepollex with base and two segments; prehallux with base and one segment; frontoparietal fontanelle partially exposed; advertisement call with one note composed of two isolated pulses per call; call dominant frequency ranging 4,380–4,884 Hz; diploid chromosome number 22; and Ag-NORs on 8q subterminal. In addition, its 16S rDNA sequence shows high genetic distances when compared to sequences of related species, which provides strong evidence that the new species is an independent lineage.
Contribution from different domains for creativity management in the context of innovation
Authors: Wielewicki Patrícia , Roda Rui Ferreira 
Published: May 2018

Creativity is an ever-increasing theme of interest in the context of management due to its importance for the innovation process. Current literature suggests that the interaction between the concepts of innovation and creativity is not clear. Both phenomena are cognitive and nebulous concepts and therefore are difficult to access by traditional research approaches. Considering creativity management in the scope of innovation processes faced by organizations, this study aims at contributing for the clarifying the relation between creativity and innovation by analyzing it under the point of view of the three domains: design, haute cuisine and art. That research strategy is based on the need for a systemic view of creativity, standing out the growing interest in the field of creativity for the study of processes in different domains. The study articulates two investigation methods structured in two parts: (i) literature review and (ii) systematic literature review. Both methods are bound to the construction of a theoretical framework which points out contributes of the studied domains for the optimization of creative processes in the organizational context. The study suggests the existence of three integrated models of creativity management in the context of innovation, each one referring to a given domain analyzed. The framework presented is featured as a contribute for enterprises in the search for new creativity management models for innovation, as well as a starting point for the conception of a more robust theoretical body for the study of different creative processes in different domains in the context of innovation.

ObjectiveDiverticulosis is extremely common in western society. A recent study has shown that outpatient, nonantibiotic management of acute uncomplicated diverticulitis may be a feasible and safe option. However, the ability to identify these patients is still difficult. This study explores the ability of white cell count, C-reactive protein, and bilirubin in differentiating patients with complicated and uncomplicated diverticulitis, as well as progression to surgical intervention.MethodsThis is a retrospective study of patients admitted with acute diverticulitis over a 5-year period (2009–2014) at a single institution in Australia. Patients were classified into 3 groups; uncomplicated diverticulitis, complicated diverticulitis without surgery, and complicated diverticulitis with surgery. Analysis of variance (ANOVA) and Bonferroni's post hoc analyses were used to compare markers across the groups.ResultsA total of 541 patients met the inclusion criteria for this study. One-way ANOVA showed a significant difference in white cell count (P &lt; 0.0001), C-reactive protein (P &lt; 0.0001), and bilirubin (P = 0.0006) between all 3 groups. Post hoc analyses showed a significant difference in white cell count, C-reactive protein, and bilirubin when comparing uncomplicated diverticulitis against complicated diverticulitis without surgery (P &lt; 0.05) and complicated diverticulitis with surgery (P &lt; 0.05). White cell count also showed a significant difference when comparing complicated diverticulitis without surgery and complicated diverticulitis with surgery (P &lt; 0.05).ConclusionsWhite cell count, C-reactive protein, and bilirubin can distinguish between uncomplicated and complicated diverticulitis.
Estudo in vitro da lisura superficial em resinas compostas, após imersão em café e Coca-Cola®
Authors: Figueredo Carlos Marcelo S. , Sampaio Filho Hélio Rodrigues , Paes Paula Nunes Guimarães 
Published: May 2018

O objetivo deste trabalho foi analisar a diferença na rugosidade superficial de três resinas compostas submetidas a ciclos de imersão em três soluções pigmentantes. A amostra foi dividida em 4 grupos, de acordo com o tipo de solução de imersão: no Grupo I, saliva artificial (controle); no Grupo II, café; no Grupo III, Coca-Cola®; e, no Grupo IV, café seguido de Coca-Cola®. Cada grupo foi dividido em 3 subgrupos (N=9) de cada tipo de resina. Os corpos-de-prova foram levados à estufa a 37ºC (±1ºC), mergulhados em saliva artificial e estocados por uma semana. Após esse procedimento, todas as amostras sofreram três ciclos diários de imersão durante um período de 30 dias, após o qual tiveram sua lisura superficial avaliada no rugosímetro (Ra). Após a análise dos resultados pôde-se concluir que as imersões em Coca-Cola® e em Café e Coca-Cola® diminuem significativamente a rugosidade em todos os materiais, e a imersão em Café aumentou a rugosidade na Durafil® e na Esthet X®. A corrosão pode ter sido o processo responsável pelo aumento na sua lisura superficial, conferido aos materiais após a imersão em Coca-Cola®.
Ocorrência de Klebsiella pneumoniae e outros coliformes em sabão neutro líquido utilizado em um berçário de hospital
Authors: Moreira Ana Cristina Azevedo , Carvalho José Luiz Moreira de 
Published: May 2018

Foi constatado, no berçário de um hospital da rede pública de Salvador, um surto de infecção hospitalar causado por Klebsiella pneumoniae. Para detectar a origem da infecção, foram realizadas análises microbiológicas em diversas possíveis fontes de contaminação exógenas. Verificou-se, na água com sabão, utilizada no banho dos recém-nascidos, a presença de Klebsiella pneumoniae e outros coliformes. Não tendo sido constatada contaminação na água que servia ao berçário, foram examinadas várias amostras do sabão neutro líquido utilizado, sendo nelas isolados Klebsiella pneumoniae, Enterobacter cloacae e outros coliformes. Amostras de sabão de diferentes lotes foram então analisadas, constatando-se contaminação apenas no lote enviado ao hospital. O fabricante atribuiu a contaminação desse lote ao uso de água não tratada, de procedência desconhecida, no processo de fabricação do sabão. Os resultados obtidos nessa investigação apontam o sabão neutro líquido como uma possível fonte de infecção hospitalar, normalmente não considerada como tal, e mostram os riscos que a não observância de boas práticas de fabricação podem acarretar para os usuários de produtos de higiene e limpeza.
Ampli: A Construction Set for Paperfluidic Systems

Published: May 2018

AbstractThe design and fabrication of reconfigurable, modular paperfluidics driven by a prefabricated reusable block library, asynchronous modular paperfluidic linear instrument‐free (Ampli) block, are reported. The blocks are inspired by the plug‐and‐play modularity of electronic breadboards that lower prototyping barriers in circuit design. The resulting biochemical breadboard is a paperfluidic construction set that can be functionalized with chemical, biological, and electrical elements. Ampli blocks can form standard paperfluidic devices without any external instrumentation. Furthermore, their modular nature enhances fluidics in ways that fixed devices cannot. The blocks' ability to start, stop, modify, and reverse reaction flows, reagents, and rates in real time is demonstrated. These enhancements allow users to increase colorimetric signals, fine tune reaction times, and counter check multiplexed diagnostics for false positives or negatives. The modular construction demonstrates that field‐ready, distributed fabrication of paper analytical systems can be standardized without requiring the “black box” of craft and technique inherent in paper‐based systems. Ampli assembly and point‐of‐care redesign extends the usability of paper analytical systems and invites user‐driven prototyping beyond the lab setting demonstrating “Design for Hack” in diagnostics.
Ultrafast Water Permeation in Graphene Nanostructures Anomalously Enhances Two‐Phase Heat Transfer

Published: May 2018

AbstractThe unique property of ultrafast water transport in graphene nanoplatelets (GNPs) coating is attributed to the frictionless interaction between the smooth hydrophobic carbon nanostructures and the well‐ordered hydrogen bonds of water molecules, whereas the driving force originates from the randomly distributed hydrophilic functionalities. The anomalous two‐phase heat transfer enhancement that results from this distinctive property of GNPs‐coating is investigated. The fast water permeation property of graphene enables the formation of ultrathin water film that synergizes the evaporation and the circulation of water in a two‐phase closed thermosyphon (TPCT). In addition, the GNPs‐coating which performs as a hydrophilic surface, improves the droplet nucleation during condensation and its fast water permeation property augments the circulation of condensate back to the evaporator. Ultimately, the ultrafast water permeation property of GNPs‐coating enhances the efficiencies of all the three main processes taking place in a TPCT, namely, evaporation, condensation, and circulation of condensate, leading to a maximum enhancement of 80.7% in the effective thermal conductance and 116.3% in the evaporative heat transfer coefficient. The experimental results are supported by the molecular dynamics simulations. A great potential for the application of GNPs‐coating in the phase‐change heat transfer devices is envisaged.
Reduction‐Triggered Transformation of Disulfide‐Containing Micelles at Chemically Tunable Rates

Published: May 2018

AbstractA dilemma exists between the circulation stability and cargo release/mass diffusion at desired sites when designing delivery nanocarriers and in vivo nanoreactors. Reported herein are disulfide‐crosslinked (DCL) micelles exhibiting reduction‐triggered switching of crosslinking modules and synchronized hydrophobic‐to‐hydrophilic transition. Tumor cell targeted DCL micelles undergo cytoplasmic milieu triggered disulfide cleavage and self‐immolative decaging reactions at chemically adjustable rates, generating primary amine moieties. Extensive amidation reactions with neighboring ester moieties then occur because of the high local concentration and suppression of the apparent amine pKa value within the hydrophobic cores, thus leading to the transformation of crosslinking modules and formation of tracelessly crosslinked (TCL) micelles, with hydrophilic cores, inside live cells. We further integrate this design principle with theranostic nanocarriers for selective intracellular drug transport guided by enhanced magnetic resonance (MR) imaging performance.
Ultra‐Narrow‐Band Blue‐Emitting Oxoberyllates AELi2[Be4O6]:Eu2+ (AE=Sr,Ba) Paving the Way to Efficient RGB pc‐LEDs
Authors: Strobel Philipp , Maak Christian , Weiler Volker , Schmidt Peter J. , Schnick Wolfgang 
Published: May 2018

AbstractHighly efficient phosphor‐converted light‐emitting diodes (pc‐LEDs) are popular in lighting and high‐tech electronics applications. The main goals of present LED research are increasing light quality, preserving color point stability and reducing energy consumption. For those purposes excellent phosphors in all spectral regions are required. Here, we report on ultra‐narrow band blue emitting oxoberyllates AELi2[Be4O6]:Eu2+ (AE=Sr,Ba) exhibiting a rigid covalent network isotypic to the nitridoalumosilicate BaLi2[(Al2Si2)N6]:Eu2+. The oxoberyllates’ extremely small Stokes shift and unprecedented ultra‐narrow band blue emission with fwhm ≈25 nm (≈1200 cm−1) at λem=454–456 nm result from its rigid, highly condensed tetrahedra network. AELi2[Be4O6]:Eu2+ allows for using short‐wavelength blue LEDs (λem<440 nm) for efficient excitation of the ultra‐narrow band blue phosphor, for application in violet pumped white RGB phosphor LEDs with improved color point stability, excellent color rendering, and high energy efficiency.

Published: May 2018

AbstractSoybean is a major source of oil for food, feed, and biofuel production. Mutagenesis is a tool for creating unique traits useful in breeding programs. The aim of this study is to use nonhypothesis statistical testing methods to make decisions about a mutagenic population. To this end, a total of 1037 mutation lines and 28 wild‐type lines were analyzed for fatty‐acid composition and protein content. Principal component analysis (PCA) was used to analyze the fatty acid profile, multivariate analysis of variance (MANOVA) to build a selection model for seed weight per plant and weight per 10 seeds, and clustering in conjunction with power analysis to determine the minimum number of individuals needed to create a MANOVA selection model for the oil to protein content. Five of the 35 possible entries were identified by PCA analysis for stearic acid and four of 16 possible entries for oleic acid. Interestingly, most of the selected mutants were validated genetically. In fact, selected mutants with high seed stearic acid or high seed oleic acid contents were verified to carry mutations on GmFAD2‐1A, GmFAD2‐1B, and GmSACPD‐C genes. This shows a promising method of identifying smaller portion of the population to screen for desired mutations.

Published: May 2018

AbstractA variety of alkyl peresters and alkyl diacyl peroxides, which are readily accessible from carboxylic acids, are utilized as general primary, secondary, and tertiary alkylating reagents for iron‐catalyzed vinylic C−H alkylation of vinyl arenes, dienes, and 1,3‐enynes. This transformation affords olefinic products in up to 98 % yield with high E/Z values. A broad range of functionalities, including carboxyl, boronic acid, methoxy, ester, amino, and halides, are tolerated. This protocol provides a facile approach to some olefins that are difficult to access, and hence, offers an alternative to existing systems. The synthetic utility of this method is demonstrated by late‐stage functionalization of selected natural‐product derivatives.

Authors: Wilhelm Sebastian , Curbach Manfred 
Published: May 2018

AbstractDer vorliegende Artikel beschreibt die Entwicklung von Druckgehäusen aus ultrahochfestem Beton für Tiefseeanwendungen im Rahmen der Helmholtz Allianz ROBEX. Neben grundlegenden Untersuchungen zum Materialverhalten von UHPC, wie zeitabhängige oder mehraxiale Druckfestigkeit und E‐Modul, Bruchdehnung, Größeneffekt, Einfluss von Wärmebehandlung und Salzwasserlagerung oder Porositätsmessungen, wurden auch diverse Studien zu Konstruktionsgrundsätzen für wiederverschließbare Druckgehäuse durchgeführt. Die Experimente wurden begleitend numerisch simuliert und das nichtlineare Materialmodell multiPlas in ANSYS anhand der gewonnenen experimentellen Daten kalibriert. Neben einer Vielzahl an Druck‐ und Implosionsversuchen von Betongehäusen im Labor wurden zwei je einjährige Feldstudien in der Arktis in 2500 m Tiefe erfolgreich absolviert, um die Dauerhaftigkeit der Betongehäuse und den Einfluss der maritimen Umgebung auf UHPC zu untersuchen. Dabei konnten Ergebnisse zum Kriechen von UHPC unter hoher Dauerlast, zur Diffusionsdichtheit und zum Einfluss der Calcit‐Kompensationstiefe gewonnen werden. Die gewonnenen Erkenntnisse wurden in Bemessungsempfehlungen zusammengefasst.
Rosenstein‐Pavillon

Published: May 2018

AbstractDer Rosenstein‐Pavillon ist eine funktional gradierte Betonschale, die für die Sonderausstellung „baubionik – biologie beflügelt architektur“ im Stuttgarter Schloss Rosenstein entworfen und gebaut wurde. Die dort präsentierten Exponate zeigen die Forschungsergebnisse des Sonderforschungsbereichs TRR 141 „Biological Design and Integrative Structures“, in dem biologische Vorbilder im Hinblick auf eine mögliche Abstraktion von Wirkprinzipien und deren Übertragung auf Objekte und Technologien des Bauwesens untersucht werden. Der Pavillon ist ein Prototyp der Implementierung eines Konstruktionsprinzips leichter, aber starker Strukturen, die anhand struktureller Biomaterialien als Inspirationsquelle für gewichtsoptimierte Tragsysteme entwickelt wurden. Im Zentrum der Forschung stand das bionische Prinzip der Strukturoptimierung durch die lokale Anpassung von mechanischen Eigenschaften an äußere und innere Gegebenheiten. In den technischen Disziplinen ist dieses Prinzip auch als funktionale Gradierung bekannt und wird in den Materialwissenschaften, der Medizin, dem Maschinenbau und dem Bauingenieurwesen in großer Breite angewendet – Voraussetzung hierfür ist die Entwicklung von Werkstoffen und Strukturen mit Eigenschaften, die lokal an statische, mechanische, physikalische oder sonstige funktionelle Anforderungen angepasst werden können.Im vorliegenden Beitrag wird vorgeschlagen, das Prinzip der Gradierung auf den Bereich des Designs und der Architektur auszudehnen – die Material‐ und Energieeffizienz des Gebäudes soll als ebenso wichtig angesehen werden wie andere Entwurfsfaktoren. Dies ist insbesondere im Hinblick auf die zunehmende Verknappung der natürlichen Ressourcen im Kontrast zu einer stetig wachsenden Bevölkerung von besonderer Bedeutung.
