Authors: Campanella Carlo Edoardo , Cuccovillo Antonello , Campanella Clarissa , Yurt Abdulkadir , Passaro Vittorio M. N.
Published: September 2018

Fibre Bragg grating (FBG) strain sensors are not only a very well-established research field, but they are also acquiring a bigger market share due to their sensitivity and low costs. In this paper we review FBG strain sensors with high focus on the underlying physical principles, the interrogation, and the read-out techniques. Particular emphasis is given to recent advances in highly-performing, single head FBG, a category FBG strain sensors belong to. Different sensing schemes are described, including FBG strain sensors based on mode splitting. Their operation principle and performance are reported and compared with the conventional architectures. In conclusion, some advanced applications and key sectors the global fibre-optic strain sensors market are envisaged, as well as the main market players acting in this field.
Thermomechanical Noise Characterization in Fully Monolithic CMOS-MEMS Resonators
Authors: Perelló-Roig Rafel , Verd Jaume , Bota Sebastià , Segura Jaume
Published: September 2018

We analyzed experimentally the noise characteristics of fully integrated CMOS-MEMS resonators to determine the overall thermomechanical noise and its impact on the limit of detection at the system level. Measurements from four MEMS resonator geometries designed for ultrasensitive detection operating between 2-MHz and 8-MHz monolithically integrated with a low-noise CMOS capacitive readout circuit were analyzed and used to determine the resolution achieved in terms of displacement and capacitance variation. The CMOS-MEMS system provides unprecedented detection resolution of 11 yF·Hz−1/2 equivalent to a minimum detectable displacement (MDD) of 13 fm·Hz−1/2, enabling noise characterization that is experimentally demonstrated by thermomechanical noise detection and compared to theoretical model values.
Design and Implementation of a Stereo Vision System on an Innovative 6DOF Single-Edge Machining Device for Tool Tip Localization and Path Correction
Authors: López-Estrada Luis , Fajardo-Pruna Marcelo , Sánchez-González Lidia , Pérez Hilde , Fernández-Robles Laura , Vizán Antonio
Published: September 2018

In the current meso cutting technology industry, the demand for more advanced, accurate and cheaper devices capable of creating a wide range surfaces and geometries is rising. To fulfill this demand, an alternative single point cutting device with 6 degrees of freedom (6DOF) was developed. Its main advantage compared to milling has been the need for simpler cutting tools that require an easier development. To obtain accurate and precise geometries, the tool tip must be monitored to compensate its position and make the proper corrections on the computer numerical control (CNC). For this, a stereo vision system was carried out as a different approach to the modern available technologies in the industry. In this paper, the artificial intelligence technologies required for implementing such vision system are explored and discussed. The vision system was compared with commercial measurement software Dino Capture, and a dedicated metrological microscope system TESA V-200GL. Experimental analysis were carried out and results were measured in terms of accuracy. The proposed vision system yielded an error equal to ±3 µm in the measurement.
Driving among Adolescents with Autism Spectrum Disorder and Attention-Deficit Hyperactivity Disorder
Authors: Bishop Haley , Boe Logan , Stavrinos Despina , Mirman Jessica
Published: September 2018

Over the past several decades there has been a surge of research on the contextual, biological, and psychological factors associated with transportation safety in adolescence. However, we know much less about the factors contributing to transportation safety among adolescents who do not follow a typical developmental trajectory. Adolescents with developmental disabilities (DD) such as Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) have a wide range of behavioral and psychological deficits that may make the complex task of driving even more challenging. Because these adolescents often retain characteristic symptoms of their disorder into adulthood, it may impede their ability to achieve important milestones during the developmental transition from adolescent to adult. As the motivating force behind autonomous living and employment, the capacity for independent transportation is paramount to an adolescent’s overall success. This critical review will draw from the current body of literature on adolescent drivers with developmental disabilities to determine (1) areas of impairment; (2) safety risk factors; and (3) effective interventions for improving driving safety in this vulnerable population of adolescent drivers between the ages of 15–22. This review will also identify important unanswered research questions, and summarize the current state of the literature.
L’acceptation et l’appropriation des ENT (Espaces Numériques de Travail) par les enseignants du primaire
Authors: Codreanu Elena , Michel Christine , Bobillier-Chaumon Marc-Eric , Vigneau Olivier
Published: September 2018

FRE: Cet article présente une évaluation des conditions d’usage d’un ENT (appelé ONE) par des enseignants du primaire. Elle est réalisée à travers deux études utilisant la théorie de l’activité comme cadre d’analyse. La première évalue les activités réelles effectuées par les enseignants sur l’ENT en analysant thématiquement le contenu des publications faites sur l’ENT, afin de comprendre comment les utilisateurs s’approprient l’outil. La seconde évalue les facteurs d’acceptation et de refus de la technologie, en décrivant la manière dont les enseignants vivent et perçoivent le rôle que l’ENT peut jouer sur l’évolution de leurs pratiques professionnelles (en les maintenant, les transformant ou les restreignant). Ces études ont permis de montrer que l’appropriation de ONE s’est produite notamment à travers les activités pédagogiques et de communication avec les parents d’élèves. L’acceptation favorable de cet ENT est due à la facilité d’usage et l’adéquation de l’interface aux enseignants et jeunes enfants.
Abstraction des fonctionnalités d'une plateforme de formation pour la mise en oeuvre de langages de scénarisation
Authors: Loiseau Esteban , Laforcade Pierre , El mawas Nour , Iksal Sébastien
Published: September 2018

The GraphiT project aims to help teachers in specifying of pedagogically sound learning scenarios that can be executed for automatically setting-up the related Learning Management System course. We intend to provide teachers with LMS-specific instructional design languages and editors. To achieve this goal, we have to raise the LMS semantics in order to enrich the pedagogical expressiveness of the produced models. We propose a specific LMScentered approach for abstracting the low-level concepts and turning these semantics into higher-level pedagogical building blocks. We present and illustrate our propositions focused on the Moodle LMS.

Published: September 2018

Cet article a trait à l’apprentissage collectif mis en place dans le cadre d’activités de programmation du robot de sol Bee-Bot réalisées en contexte scolaire. Nous y proposons une méthode d’analyse des comportements sociaux de jeunes enfants amenés à collaborer au sein de groupes de travail de taille restreinte. Cette méthode a été mise en oeuvre dans le cadre d’une observation participante dont l’objet était d’analyser l’investissement personnel de chacun des 21 élèves du primaire âgés de 5 à 6 ans et de déterminer la manière dont la collaboration intra-groupe s’opère. Les résultats de la recherche ont permis de déterminer cinq types de profils : les comportements de compétiteurs, de leaders, de conciliants, de suiveurs et de désinvestis ainsi que de mettre en évidence des dynamiques collectives en fonction de la combinaison des profils.

MOOC : un mot, plusieurs facettes. Pour une caractérisation systématique des MOOC orientée ingénierie pédagogique
Authors: Ortoleva Giulia , Peltier Claire , Bétrancourt Mireille
Published: September 2018

Although the term MOOC is prevalent in the media coverage and in the scientific literature, the actual courses offer a wide spectrum of variation, leading to a large number of initiatives proposing classifications and typologies in the last two years. This paper describes a complementary approach of systematic characterisation that consists of identifying the dimensions according to which the specificity of MOOC and their variation can be best described. Deliberately focused on instructional design issues, the model proposes seven dimensions of characterisation whose relevance is assessed through the analysis of four examples of MOOC.
L’adhésion des étudiants à la classe inversée : une approche par le style d’apprentissage
Authors: Thobois-Jacob Laëtitia , Christoffel Éric , Marquet Pascal
Published: September 2018

Les étudiants peuvent être plus ou moins favorables à la démarche de la classe inversée (Chevalier et Adjedj, 2014) et, par conséquent, s’engager dans les tâches proposées à distance de façon très inégale. Afin de mieux comprendre ce phénomène, nous avons mobilisé les styles et les modes d’apprentissage issus du cycle de l’apprentissage expérientiel de Kolb (1984) pour étudier comment, selon leur style et leur mode d’apprentissage, les étudiants perçoivent les capsules vidéo (que nous appellerons «vidéo-cours » ) consultées à distance et les activités menées en présentiel. Nos résultats montrent que les étudiants qui apprennent par «conceptualisation abstraite » sont les plus critiques envers la classe inversée ; en revanche ceux qui apprennent principalement par «expérimentation active » ont une perception plus positive des effets de la classe inversée sur leur apprentissage.
The Type I Superluminous Supernova PS16aqv: Lightcurve Complexity and Deep Limits on Radioactive Ejecta in a Fast Event
Authors: Blanchard P. K. , Nicholl M. , Berger E. , Chornock R. , Margutti R. , Milisavljevic D. , Fong W. , MacLeod C. , Bhirombhakdi K.
Published: September 2018

We present UV/optical observations of PS16aqv (SN 2016ard), a fast-evolving Type I superluminous supernova (SLSN-I) that reached a peak absolute magnitude of M

r
 ≈ −22.1. The lightcurves exhibit a significant undulation at 30 rest-frame days after peak, with a behavior similar to undulations seen in the slowly fading SLSN-I SN 2015bn. This similarity strengthens the case that fast and slow SLSNe-I form a continuum with a common origin. At ≈80 days after peak, the lightcurves exhibit a transition to a slow decline, followed by significant steepening, indicative of a plateau phase or a second significant undulation. Deep limits at ≈280 days after peak imply a tight constraint on the nickel mass, M
Ni ≲ 0.35 M
⊙ (lower than for previous SLSNe-I), and indicate that some SLSNe-I do not produce significantly more nickel than normal Type Ic SNe. Using MOSFiT, we model the lightcurve with a magnetar central engine model and find P
spin ≈ 0.9 ms, B ≈ 1.5 × 1014 G, and M
ej ≈ 16 M
⊙. The implied rapid spin-down time and large reservoir of available energy coupled with the high ejecta mass may account for the fast lightcurve and slow spectroscopic evolution. We also study PS16aqv’s location within its host galaxy and find that it occurred at an offset of 2.46 ± 0.21 kpc from the central star-forming region. Aside from high extinction, the host properties are similar to most other SLSN-I host galaxies. The complexity in the lightcurves of PS16aqv and other events highlights the importance of obtaining well-sampled lightcurves for exploring deviations from a uniform decline.

Objective.

To identify clinical features that define disease activity in pediatric localized scleroderma (LS), and determine their specificity and importance.

Methods.

We conducted a multicenter prospective study of patients with active and inactive LS skin lesions. A standardized evaluation of a single designated study lesion per subject was performed at 3 visits. We evaluated the pattern and correlation between assessed features and physician’s global assessments of activity (PGA-A).

Results.

Ninety of 103 subjects had evaluable data; 66 had active and 24 inactive disease. Subjects had similar age of onset, sex, and disease patterns. Linear scleroderma was the most common subtype. Features specific for active disease included erythema, violaceous color, tactile warmth, abnormal skin texture, and disease extension. Scores for these variables changed over time and correlated with PGA-A of the lesion. Active and inactive lesions could not be distinguished by the presence or level of skin thickening, either of lesion edge or center. However, in active lesions, skin thickening scores did correlate with PGA–A scores. Regression analysis identified the combination of erythema, disease extension, violaceous color, skin thickening, and abnormal texture as predictive of PGA-A at study entry. Damage features were common irrespective of activity status.

Conclusion.

We identified variables strongly associated with disease activity, expanding upon those used in current measures, and determined their relative importance in physician activity scoring. Skin thickening was found to lack specificity for disease activity. These results will help guide development of a sensitive, responsive activity tool to improve care of patients with LS.
De l’intérêt des serious games comme méthode de restitution des apprentissages, sous stress aigu, en crise

En situation de crise, le comportement d’un décideur est inévitablement influencé par les contraintes de son environnement. Une étude empirique, reposant sur un serious game , menée auprès de 72 individus, démontre que la performance et la capacité de restitution des compétences acquises par les individus dépendent de leur niveau de stress aigu, des stratégies de prévention mises en place et du degré de transformation des savoirs et savoir-faire en routines.
Politique d’innovation et ses facteurs
Authors: Lewis Jenny M. , Ricard Lykke Margot , Klijn Erik Hans
Published: September 2018

Le besoin de comprendre l’innovation dans le cadre du secteur public se fait de plus en plus sentir. Il y a aussi la nécessité de développer la théorie, de la tester de manière empirique et de comparer les choses d’un pays à l’autre. Avec le présent article, notre intention est de comprendre les facteurs qui ont une influence sur la capacité d’innovation. Nous y examinons la capacité d’innovation autoproclamée de trois gouvernements municipaux européens (Barcelone, Copenhague et Rotterdam) sur le plan des facteurs d’innovation (structures, processus et facteurs contextuels), du réseautage externe (niveaux de communication en dehors de la municipalité) et des qualités de leadership. Nous nous sommes servis des résultats d’une enquête en ligne menée auprès d’administrateurs de haut niveau dans les villes ( n = 323) pour analyser de manière empirique les relations entre ceux-ci au moyen d’une modélisation par équation structurelle. Le leadership a une influence plus forte que les facteurs d’innovation et le réseautage externe sur la capacité d’innovation autoproclamée pour ces trois gouvernements municipaux. Remarques à l’intention des praticiens L’innovation dans le secteur public est une thématique très importante pour les gestionnaires publics étant donné que l’on attend de plus en plus des organes gouvernementaux. La capacité d’innovation est liée aux facteurs d’innovation et aux obstacles à l’innovation, à l’ampleur des contacts qu’entretiennent les individus avec des personnes en dehors de leur organisation et au leadership. La présente étude empirique menée auprès de trois villes indique que le leadership a une influence plus grande sur la capacité d’innovation que les structures, les processus et les facteurs contextuels qui favorisent l’innovation, de même que l’ampleur des contacts extérieurs qu’entretiennent les gestionnaires publics en dehors de leurs organisations. Par ailleurs, pour Barcelone et Copenhague, le type de gouvernance du réseau et les types transformationnels sont les facteurs qui ont le plus d’influence sur l’innovation, alors que pour Rotterdam, c’est le type entrepreneurial, suivi du type de la gouvernance du réseau.
Règles du jeu dans la coopération transfrontalière : différences juridico-administratives dans la prévention de la criminalité entre la Finlande et la Russie
Authors: Heusala Anna-Liisa , Koistinen Jarmo
Published: September 2018

Le présent article illustre la dynamique de la coopération transfrontalière bilatérale entre deux partenaires juridico-administratifs très différents. L’analyse s’appuie sur les résultats empiriques d’une étude de cas concernant la coopération bilatérale entre la Finlande et la Russie en matière de prévention de la criminalité. À l’heure actuelle, les différences entre les législations nationales, ainsi que l’évolution rapide de l’environnement administratif, rendent cette coopération difficile. L’étude de cas a montré que la coopération bilatérale, qui est la forme dominante de coopération entre les États membres de l’UE et la Russie, est actuellement affectée par des structures multilatérales et bilatérales disjointes voire concurrentes, des différences en matière de droit pénal et de procédure pénale, des écarts entre les traités internationaux et la législation nationale, des variations locales et régionales des pratiques, une confiance institutionnelle faible et des changements soudains de politique. Les résultats indiquent que l’efficacité des réseaux transfrontaliers ne peut être évaluée strictement en termes de résultats quantitatifs. Le développement à long terme de la coopération exige à la fois une compréhension réaliste des contraintes juridico-administratives et un engagement fort au niveau politique national et supranational. Remarques à l’intention des praticiens Le développement futur à long terme de la coopération transfrontalière en matière de prévention de la criminalité entre les États membres de l’UE et la Fédération de Russie nécessite des instruments de prévention de la criminalité plus souples et l’institutionnalisation d’équipes communes d’enquête. Le modèle optimal d’enquêtes criminelles conjointes avec les autorités russes pourrait être un modèle où les preuves du protocole d’enquête préliminaire pourraient être acquises par le biais de connexions régionales directes entre les autorités. Concrètement, cela nécessite une confiance pratique beaucoup plus forte entre les différents niveaux d’autorités des États membres de l’UE et de la Fédération de Russie, la réconciliation des différences dans les législations nationales et un engagement politique à long terme au plus haut niveau.
Le post-nouveau management public : un nouveau paradigme administratif pour la Chine ?
Authors: Christensen Tom , Fan Yongmao
Published: September 2018

En partant de trois perspectives théoriques – instrumentale, culturelle et mythique –, le présent article analyse les raisons de l’émergence mondiale des réformes post-nouveau management public et résume les caractéristiques typiques de ces mesures. Plus spécifiquement, il explore le lien entre le post-nouveau management public et les réformes du secteur public en Chine, et soutient que les réformes en cours en Chine, comme la réforme du super-ministère, la réglementation de l’industrie, la politique de logement abordable, les réformes sociales et de soins de santé, ainsi que la campagne de lutte contre la corruption, ont mis en lumière divers aspects des mesures post-nouveau management public. Cependant, étant donné que les systèmes administratifs publics complexes de la Chine sont plus centralisés que dans de nombreux pays occidentaux, elle est confrontée à de grands défis pour décider des réformes et les mettre en œuvre. Remarques à l’intention des praticiens Les réformes administratives examinées démontrent que la Chine imite les réformes post-nouveau management public et les adapte aux traditions culturelles chinoises. Le cas de la Chine révèle que le secteur public est une combinaison complexe d’éléments de nouveau management public et de réformes post-nouveau management public dans un processus où de nouveaux éléments de réforme sont continuellement ajoutés aux anciens. Les réformes de la Chine sont toujours en cours ; ces dernières années, le pays s’est davantage concentré sur la réforme économique, la décentralisation et l’efficacité ; mais aujourd’hui, ses réformes se tournent vers la stabilité sociale, l’ordre politique et le contrôle central.
Patients With Valgus Alignment and Patients With Varus Alignment Are Not Mere Opposites of Each Other Prior to Total Knee Arthroplasty
Authors: Schexnayder Stuart , Arnaud Ethan , Schexnayder Lyndsey , Patel Vikas , Leonardi Claudia , Dasa Vinod
Published: September 2018

Although it is common practice to assess alignment prior to total knee arthroplasty, preoperative knee alignment and its effect on patient-reported outcomes (PROs) postoperatively has not been well studied. The purpose of this retrospective study was to determine if there are differences in PROs between patients with valgus deformities and patients with varus deformities. Further, this study assessed the baseline differences between these 2 groups preoperatively. Patients were placed into either the valgus or the varus group. Data collected included age, sex, race, height, weight, body mass index, knee alignment, Kellgren–Lawrence grade, and 2 PRO measures. Patient-reported outcomes were assessed preoperatively and at 5 scheduled follow-up visits during the first year postoperatively. The authors found that a higher percentage of female patients had a valgus deformity (84.9%). The varus group tended to have a higher body mass index. Radiographs revealed differences in tibia and femur deformities. The overall deformity was less in patients with a valgus deformity than in patients with a varus deformity (mean, 6.6° [SD, 4.4°] vs 8.6° [SD, 4.8°],
P
=.010). Preoperative Knee injury and Osteoarthritis Outcome Score symptoms were significantly worse in the valgus group (
P
=.033). After adjusting for the significant baseline differences, all patients reported improved PROs during the postoperative period (
P
<.0001). Preoperatively, patients with valgus deformities and patients with varus deformities do not appear to be mere opposites of one another. The groups differed by sex, Knee injury and Osteoarthritis Outcome Score symptoms, and tibia, fibula, and overall deformity. Postoperatively, there were no significant differences in PROs during and up to 1 year. [

Short-Segment Fixation With Percutaneous Pedicle Screws in the Treatment of Unstable Thoracolumbar Vertebral Body Fractures
Authors: Sahai Nikhil , Faloon Michael J. , Dunn Conor J. , Issa Kimona , Sinha Kumar , Hwang Ki Soo , Emami Arash
Published: September 2018

Clinical care of patients with unstable thoracolumbar vertebral body fractures may be challenging, especially in the setting of polytrauma patients who require other acute intervention. Compared with the traditional open approach, percutaneous short-segment fixation constructs place less surgical burden on patients regarding operative time and blood loss. Between 2008 and 2012, 32 patients with a mean age of 49 years (range, 19–80 years) underwent percutaneous short-segment fixation at the authors' institution and had a minimum of 6 months of complete clinical and radiographic follow-up. Load-sharing classification scores were determined. Outcomes evaluated included anterior body height, posterior body height, local kyphosis, regional kyphosis, thoracolumbar junctional kyphosis, mean operative time, and total blood loss. Standard binomial and categorical comparative analyses were performed. All load-sharing classification scores were 7 or less, and 11 of the 32 patients were polytrauma patients requiring surgery. No difference was seen between preoperative and late measurements of anterior body height, posterior body height, local kyphosis, regional kyphosis, or thoracolumbar junctional kyphosis. There were no complications, revisions, or anterior corpectomies. Only 2 patients (6%) underwent elective removal of hardware at 1 year. Mean operative time was 43 minutes (range, 33–56 minutes), and mean estimated blood loss was less than 50 mL. Percutaneous short-segment fixation prevented loss of vertebral body height and progression of kyphosis in the treatment of unstable thoracolumbar fractures with load-sharing classification scores of 7 or less. This study shows that these fractures with a load-sharing classification score of 6 and 7 may be stabilized using fewer screws than traditional methods in some patients and allow polytrauma patients to undergo other acute treatment.

Le présent article situe l’œuvre de la Péruvienne Julia Codesido dans l’indigénisme aux débuts de ce mouvement culturel et social, alors que Codesido comme Sabogal, comme Daniel Hernández reviennent d’Europe au Pérou. Le cheminement inverse du Pérou vers la France est réalisé par Elena Izcue et Carmen Saco dans les années 1920. La revue Amauta dirigée par José Carlos Mariátegui est le fer de lance de l’activité indigéniste à Lima. Plusieurs reproductions de tableaux de Codesido sont publiées correspondant à l’engagement du mensuel. Après avoir présenté ces œuvres, l’article évoque l’évolution de Codesido en reliant l’épuration plastique des années 40-50 à l’activité au sein de l’Institut d’Art Péruvien fondé par José Sabogal.
Idiosyncrasie de l’indigénisme en Amérique latine. Pluralité des sources et des appropriations extra-latino-américaines
Authors: Greet Michele , Luna Anahí , Vaudry Élodie
Published: September 2018

Ce numéro 12 d'Artelogie rassemble des articles traitant des sources extra-latino-américaines de l'indigénisme dans une approche diachronique et transdisciplinaire et invite à analyser cette thématique sous l'angle des transferts culturels, des processus d'appropriations intellectuelles et plastiques ou bien des refus d'adoptions de modèles politiques et artistiques.La « négociation » entre nationalisme et internationalisme est au cœur de la problématique de ce numéro qui propose de questionner un tel processus comme une stratégie de transculturation entre l’Amérique latine et le reste du monde. Jusqu’alors majoritairement étudié comme un mouvement centripète à cette aire géographique, il convient ici d’appréhender l’indigénisme comme un phénomène centrifuge, pluriséculaire et transculturel.
Offre et fréquentation des transports publics bruxellois de 1950 à 2017
Authors: Carton Vincent
Published: September 2018

S’appuyant sur les statistiques de la STIB depuis 1950, cet article analyse les choix faits en matière d’offre de transport en commun. D’un réseau basé quasi exclusivement sur le tram, on est passé progressivement à une offre métro-tram-bus retrouvant aujourd’hui son intensité en km parcourus de 1950. Si le métro a rapidement fait consensus, il n’a pas permis de compenser les réductions de l’offre engendrées par les économies sur l’exploitation du réseau dans les années 1980. Mettre l’essentiel des moyens sur un seul mode, en particulier si sa couverture territoriale est limitée, n’est pas suffisant. Même si la relation entre l’amélioration de l’offre et le gain de clientèle n’est pas automatique, une conclusion apparaît : en 68 ans, la STIB a attiré plus d’usagers à trois reprises lorsqu’elle a amélioré l’offre sur l’ensemble du réseau, surtout les fréquences des trams et des bus, les fréquences du métro ayant toujours été élevées. L’étude éclaire le débat sur les choix possibles : faut-il investir dans une ligne de métro entre Albert et Bordet ou investir dans le réseau de surface (extension au moyen de lignes à « haut niveau de service », protection des trams et bus vis-à-vis du trafic et amélioration des fréquences) ?
Optimal duration of anticoagulant therapy in patients with venous thromboembolism
Authors: Palareti Gualtiero
Published: September 2018

Venous thromboembolism (VTE), a frequent and severe disease, has clinically important early and late complications and a strong tendency to recur. Anticoagulant therapy is the mainstay of treatment, performed by immediate administration of: a) parenteral anticoagulants followed by vitamin K antagonists (VKAs), either dabigatran or edoxaban, two direct oral anticoagulants (DOACs); or b) direct rivaroxaban or apixaban, two DOACs that can be used as single-drug approach. Treatment should last no less than 3 months in all patients though how long it should last thereafter is a more complex issue. The risk of recurrence results from several event- or patient-associated factors. Some patients have low risk and may be treated for 3 to 6 months only. Others (the majority), have a high risk of recurrence (approximately 50% in 10 years). Unfortunately, the protective effect of anticoagulation against recurrence is present only during treatment and is lost when therapy is stopped. For this reason, international guidelines recommend there be no pre-definite period of anticoagulation (e.g. 1 or 2 years, and so on) in patients at high risk and suggest instead indefinite (extended) anticoagulation, provided there is no high risk of bleeding. When the decision is difficult, adjunctive criteria may be adopted, such as male sex and abnormal Ddimer assessed after anticoagulation is stopped, to identify patients at high risk who need indefinite therapy. The use of DOACs, especially at lower doses with a lower risk of bleeding, may make indefinite anticoagulation for patients easier.
The Revelatory Text and the prologue of the Gospel of Luke
Authors: Welzen Huub
Published: September 2018

The first print of the book of Sandra Schneiders, The Revelatory Text, appeared more than 25 years ago. With the help of the hermeneutic theories of Gadamer and Ricoeur, she proposes a kind of exegesis that integrates scholarly methods and spiritual reading. In this article we investigate how the model of Sandra Schneiders is congruent with the old intuition of the lectio divina. We compare the model of Schneiders with the systematisation of the lectio divina by Guigo II, the Carthusian. As a result, we see in the text of Guigo the pre-understanding of the Carthusian spiritual life at work. And as a result we also recognise Schneiders’ transformative understanding of the subject matter of the text in the phase of the oratio and the comtemplatio. In the model of Guigo, there is also room for critical analysis in the phase of the meditation. We investigate also if the Bible itself gives indications for the kind of exegesis Schneiders proposes. What Schneiders says about pre-understanding is present in the prologue of the Gospel of Luke. Luke considers the story he tells as a history guided by God. What Luke tells about the genesis of his text belongs to the world behind the text. The world of the text is present as a well-ordered world. Luke speaks also about the transformation of the reader. In this, we recognise what Schneiders says about the world before the text and the transformative understanding of the subject matter of the text. We conclude that the model of Schneiders is innovative in relation of common academic exegesis. It is rooted in the tradition of Christian spiritual reading, and it is present in those biblical texts which indicate how to read.
Spaces for local voices? A discourse analysis of the decisions of the Convention on Biological Diversity
Authors: Parks Louisa
Published: September 2018

This article discusses the existence and shape of a discursive space for local and indigenous voices in the arena of the Convention on Biological Diversity (CBD). Critical literature on global environmental governance argues that dominant or hegemonic discourses shape international-level decision making on environmental protection, and delimit the boundaries of possible policy choices. These discourses are identified by such scholarship as reflecting a dominant worldview stemming from a capitalist view of value and a dichotomous view of nature as separate from culture, which precludes discursive spaces for worldviews based on different conceptions of value and more holistic views of nature as inextricably bound up with culture. Such worldviews are often held by indigenous peoples and local communities considered to be crucial in protecting the environment and natural resources. The present article aims to contribute to this debate by looking in detail at decisions of the parties to the CBD, which is an arena argued by some to be more open to local and indigenous voices. The article presents a discourse analysis of the CBD's decisions since its creation and up to its most recent meetings held in late 2016. The analysis applies the arguments of the critical literature to the decisions of the CBD in order to investigate how far they conform to the critical view of them, or whether, and if so to what extent, they host spaces for local and indigenous voices.

Abstract. Exposure dating has substantially improved our knowledge
about glacier advances during the Younger Dryas (YD) and the early Holocene.
The glacier development after the Last Glacial Maximum (LGM) and the timing
of morphologically evidenced, earlier Lateglacial re-advances is, however,
still widely unknown. In this study we used 10Be surface exposure and
radiocarbon dating to address these phases and corresponding landforms in
the catchment of the former Reussgletscher (central Swiss Alps). We obtained
clear indication for moraine deposition prior to the YD. The oldest samples
predate the Bølling–Allerød interstadial (>14.6 ka).
Morphostratigraphically even older lateral moraines, probably corresponding
to terminal positions in the Lake Lucerne, could not be dated conclusively.
Due to the geomorphological constraints of the sampling environment, the
establishment of a local pre-YD chronology remains a challenge: moraines
with adequate numbers of datable boulders were rarely preserved, and age
attributions based on few samples are complicated by outliers.

The Rupture as Ethical Imperative: Reading thePhaedrusthrough Levinas's Ethics
Authors: Musgrave Kevin
Published: September 2018

Reading the Phaedrus through Levinas's ethics for the other, I argue that the dialogic rupture in the Phaedrus offers an ethical imperative for rhetoric to respect alterity. Following James Kastely, I suggest that attempts to create a unified understanding of the dialogues within the Phaedrus miss the way in which the thematic discontinuity of the text functions philosophically and performatively. This rupture, I posit, signifies an ethical stance toward alterity that forgoes the possibility of violence and respects plurality. Such an ethical stance offers an imperative for a rhetorical ethic of listening in dialogue and suggests that rhetorical scholars return to Plato as a valuable resource for theorizing rhetorical ethics.
The Effect of Director's Individual and Family Shareholdings on Firm Performance
Authors: Wu Tsung-Che , Huang Ming-hsiang
Published: September 2018

The relation between firm performance and shareholding is a critical issue in corporate governance. In this paper, we examine if significant associations exist between firm performance and (1) directors’ shareholdings or (2) directors’ family shareholdings among Taiwanese listed firms. After addressing for possible endogeneity and controlling for firm specific variables, we find a positive association between executive director’s shareholding and firm performance. Consistent with incentive effect in agency theory, this result indicates that executive directors have incentive to maximize firms’ value. Also, we find that executive directors’ family shareholding is positively related to firm performance, which implies that executive directors may be motivated by their family members to improve firm value. The results also imply that the majority-minority agency problem can be mitigated when director’s family welfare is at stake. In addition, we divide research sample into subsets to accommodate the effect of mandatory independent director regulation in Taiwan since 2007.
Effect of designing a nursing educational protocol on frequency of epileptic attacks

Published: September 2018

Background and objective: Educating the epileptic patient represents a critical part of quality care and is considered a therapeutic outcome for those patients. This study aimed to determine epileptic patients' knowledge regarding the disease and frequency of seizure attacks prior to the implementation of the educational protocol and to evaluate the effect of an educational protocol on epileptic patient's knowledge and frequency of seizure attacks.Methods: Design: A quasi-experimental (pre-posttest) design was submit to meet the aim of the study. Patients: Sixty convenient male and female adult seizure patients were their age ranged between 18-64 years. Setting: This study was carried out in Neurological department and neurology out-patient clinic at Minia University Hospital.  Tools of data collection: Four tools were utilized; Pre/posttest questionnaire sheet, Perceived Stress Scale, Epworth Sleepiness Scale, and patient teaching booklet.Results: About 86.7% of the study sample has an unsatisfactory level of knowledge about seizures and 13.3% have satisfactory knowledge about seizures before the implementation of the protocol. While in posttest II it was noticed that 90.0% have satisfactory knowledge about seizures. There was a high positive significant correlation between perceived stress scale and frequency of attacks among the study subjects.Conclusions: An improvement in seizure patients’ knowledge after the implementation of the educational protocol. An improvement in patient’s knowledge positively reflected on minimization and control frequency of seizure attacks. Recommendation: An educational and training protocol should be planned in a continuous manner and offered on regular basis to seizure patients.
Remaining gaps in open source software for Big Spatial Data
Authors: de Sousa Luís Moreira
Published: September 2018

The volume and coverage of spatial data has increased dramatically in recent years, with Earth observation programmes producing dozens of GB of data on a daily basis. The term Big Spatial Data is now applied to data sets that impose real challenges to researchers and practitioners alike. The difficulties are partly related to a lack of tools supporting appropriate Coordinate Reference Systems (CRS). As rule, these data are provided in highly irregular geodesic grids, defined along equal intervals of latitude and longitude. Compounding the problem, users of such data end up taking geodesic coordinates in these grids as a Cartesian system, implicitly applying Marinus of Tyre's projection. A first approach towards the compactness of global geo-spatial data is to work in a Cartesian system produced by an equal-area projection. There are a good number to choose from, but those commonly supported by GIS software invariably relate to the sinusoidal or pseudo-cylindrical families, that impose important distortions of shape and distance. The land masses of Antarctica, Alaska, Canada, Greenland and Russia are particularly distorted with such projections. A more effective approach is to store and work with data in modern cartographic projections, in particular those defined with the Platonic and Archimedean solids. In spite of various attempts at open source software supporting these projections, in practice they remain today largely out of reach to GIS practitioners. This communication reviews persisting difficulties in working with worldwide big spatial data, current strategies to address such difficulties, the compromises they impose and the remaining gaps in open source software.
A Relevance Theoretical Reading of Wole Soyinka’s The Lion and the Jewel
Authors: Igwedibia Adaoma
Published: September 2018

There would be no communication, business transactions or propagation of culture and beliefs but for the existence of language. Language is the most important tool for communication. The utterances human beings make are being governed by situation, event or occurrences at a given point in time. Meaning is derived based on the context in which the utterances occur and this is the essence of pragmatics. This paper seeks to carry out an analysis of some extracts in Wole Soyinka’s The Lion and the Jewel using the relevance theory in pragmatics. Relevance theory as propounded by Sperber and Wilson (1986) claims to provide a logical and cognitive account of relevance in communication. The theory tends to explain communication that takes into account implicit inference. It argues that the hearer or reader will search for meaning in any given communication situation and having found meaning that fits his expectation of relevance meaning, he will stop processing. This is in effect is what this paper attempts to explore using The Lion and the Jewel. Speakers and writers often mean much more than they say or write and expect their hearers or readers to understand them. They will generally assume that some aspects of meanings that are not expressed in words are deducible from the context. This assumption is based on their shared environment, values, social conventions, words or grammatical structures.
Phonological Development and Phonological Processes in the Speech of an English-Arabic Bilin-gual Child
Authors: Asaad Daana Hana
Published: September 2018

This research traces the phonological development and the phonological processes in the speech of a bilingual child acquiring Jordanian Arabic and English. This trace is carried out through a thorough description of the phonological development of segments in Jordanian Arabic and English. It is also carried out through discussing the phonological processes resorted to by the child in order to simplify the production of segments in both languages. This study is the first of its kind to compare and contrast phonological processes in the speech of a bilingual child whose two first languages descend from two different linguistic families. The study also scrutinizes evidence of any influence of one language over the other. Evidence for either the Separate Development Hypothesis or the Fusion Hypothesis is also investigated. The data used in this paper are collected by the author from her own child acquiring Arabic and English simultaneously between the ages of 7 and 20 months. The child’s sound segment development showed consistency with universal trends. Phonological processes such as regressive and progressive assimilation, substitution and metathesis were found in the child’s production of English and Arabic sounds. The study provides limited evidence for the occurrence of interlanguage interference. On the other hand, the study provides strong supportive evidence for the Separate Development Hypothesis.

This study aims at investigating EFL the fourth-year students’ level of speaking anxiety. Also, the study investigates the main three factors (communication apprehension, fear of negative evaluation and low self-confidence) that contribute to increasing speaking anxiety among EFL learners. The Foreign Language Speaking Anxiety Scale (FLSAS) has been adapted to collect quantitative data and specifically measure speaking anxiety. The sample of this study was 300 fourth-year English department students at three universities in Libya. The findings of this study revealed that students experienced a moderate to high level of EFL speaking anxiety. Additionally, the findings of the study revealed that the low self-confidence factor received the highest average followed by fear of negative evaluation, and communication apprehension factors.
From indigenous education to indigenising mainstream education
Authors: Gjerpe Kajsa Kemi
Published: September 2018

The purpose of this article is to discuss the concept of “indigenous education” in Norway and Aotearoa New Zealand. The point of departure is that both states face a common challenge with regard to indigenous education: Valuable resources are used on indigenous schools, but the majority of indigenous students attend mainstream schools. The article claims that the emphasis on indigenous schools has been necessary and important as part of the indigenous political movement. Nevertheless, in order to achieve culturally appropriate education for all indigenous pupils, this article argues that there is a need to indigenise mainstream education.
