Cation-induced ring-opening and oxidation reaction of photoreluctant spirooxazine–quinolizinium conjugates
Authors: Pithan Phil M , Steup Sören , Ihmels Heiko
Published: May 2020

Two new spiroindolinonaphthoxazine derivatives with an electron-accepting styrylquinolizinium or styrylcoralyne unit, respectively, were synthesized, and the influence of such an arylvinyl substituent on the chemical and photochemical properties of the compounds was investigated. Specifically, these spirooxazines turned out to be resistant towards the photoinduced merocyanine formation, and the irradiation with light mainly led to photodegradation of the substrates. However, it was shown by colorimetric and fluorimetric screening assays as well as by detailed NMR spectroscopic and mass spectrometric studies that the addition of particular metal ions (Cu2+, Fe3+, and to a certain extent Hg2+) initially induced a ring-opening reaction that was irreversibly followed by a fast ring closure–deprotonation–oxidation sequence to give styryl-substituted naphthoxazole derivatives as the products quantitatively. For the quinolizinium-substituted spirooxazine derivative, the formation of the respective oxidation product caused the development of a broad absorption band between 425 nm and 500 nm and a new emission band at λfl = 628 nm, so that it may be employed as a selective chemosensor or chemodosimeter for the colorimetric and fluorimetric detection of Cu2+ and Fe3+.

Amauroderma s.lat. has been defined mainly by the morphological features of non-truncate and double-walled basidiospores with a distinctly ornamented endospore wall. In this work, taxonomic and phylogenetic studies on species of Amauroderma s.lat. are carried out by morphological
examination together with ultrastructural observations, and molecular phylogenetic analyses of multiple loci including the internal transcribed spacer regions (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), the largest subunit of RNA polymerase II (RPB1) and the second
largest subunit of RNA polymerase II (RPB2), the translation elongation factor 1-α gene (TEF) and the β-tubulin gene (TUB). The results demonstrate that species of Ganodermataceae formed ten clades. Species previously placed in Amauroderma s.lat.
are divided into four clades: Amauroderma s.str., Foraminispora, Furtadoa and a new genus Sanguinoderma. The classification of Amauroderma s. lat. is thus revised, six new species are described and illustrated, and eight new combinations are proposed. SEM
micrographs of basidiospores of Foraminispora and Sanguinoderma are provided, and the importance of SEM in delimitation of taxa in this study is briefly discussed. Keys to species of Amauroderma s.str., Foraminispora, Furtadoa, and Sanguinoderma are
also provided.
BENIGN AND MALICIOUS ENVY SCALE: AN ASSESSMENT OF ITS FACTOR STRUCTURE AND PSYCHOMETRIC PROPERTIES
Authors: Fam Jia Yuin , Yap Caroline Yu Li , Murugan Sri Bala , Lee Tziyun
Published: May 2020

Recent theorizing and research have proposed two subtypes of envy, namely benign envy, and malicious envy. However, many of the existing measures have mainly focused on the malicious dimension of envy. The Benign and Malicious Envy Scale (BeMaS) appears to be an appealing measure to fulfill this research need. The current study aims to evaluate the psychometric properties of BeMaS in terms of its factorial validity, construct validity, and reliability. The current study recruited two samples of university students for this purpose (N1 = 500; N2 = 356). As hypothesized, exploratory factor analysis in Study 1 yielded a two-factor structure of BeMaS (47% variance explained), which is further supported with confirmatory factor analysis in Study 2 (TLI = .919, CFI = .940, RMSEA = .078, χ2/df = 4.039). Both subtypes of envy significantly correlated with other psychological (depression, anxiety, and stress) and behavioral problems (conspicuous consumption orientation), evidencing the construct validity of BeMaS. Benign envy scale and malicious envy scale demonstrated good internal consistency in both samples. In conclusion, the psychometric assessments provided strong evidence for BeMaS as a valid and reliable measure of envy.
EMPIRICAL STUDY OF PERSONALITY AND WELL-BEING
Authors: Angelova Sofiya Georgieva
Published: May 2020

Nowadays, in psychological science, health is regarded as a multidimensional construct, which comprises not only the negative aspects of human existence but also the positive mental functioning and well-being of human being. In this context, the article herein aims at exploring the interrelationship of temperament and character with the subjective well-being of Bulgarians. The results obtained in the presented study of 443 persons from Bulgaria (men and women aged 18 to 65 M = 34.35, SD = 5.046) indicated that there was a statistically significant influence of the predictors: Self-Direction, Self-Transcendence, Positive and Negative Affect on Life Satisfaction. A significant influence was found about some predictors as Novelty Seeking, Harm Avoidance, Persistence, Self-Directedness, and Self-Transcendence on Positive Affect. Finally, a significant influence was found of the predictors: Harm Avoidance, Self-Directedness, and Self-Transcendence on Negative Affect.
Exploring culturally sustaining practice for indigenous learners in initial teacher education in Aotearoa New Zealand
Authors: Averill Robin , McRae Hiria
Published: May 2020

Culturally sustaining practices are advocated for enhancing learning experiences of Indigenous learners. Developing the use of culturally sustaining practice is challenging, in part as many educators do not have Indigenous heritage and have not themselves experienced such teaching. Here we discuss an investigation into how we develop student teacher understanding of practice culturally sustaining for Indigenous Māori learners in our initial mathematics teacher education courses. We show how a four-dimension framework (accommodation, reformation, transformation, and representation) can expose strengths and opportunities for improvement in course content and approaches towards developing culturally sustaining practices. Factors considered include education policy, resources, course development and content. Affordances (e.g., ease of use) and challenges (e.g., contextal factors) of using the framework are discussed. We demonstrate that the framework can be a useful tool for teacher educators working to strengthen their focus on developing culturally sustaining teacher practice to enhance educational opportunities of Indigenous learners.

The Galactic Center contains some of the most extreme conditions for star formation in our Galaxy, as well as many other phenomena that are unique to this region. Given our relative proximity to the Galactic Center, we are able to study details of physical processes to a level that is simply not yet possible for more distant galaxies, yielding an otherwise inaccessible view of the nuclear region of a galaxy. We recently carried out a targeted imaging survey of mid-infrared bright portions of the Galactic Center at 25 and 37 μm using the FORCAST instrument on the Stratospheric Observatory for Infrared Astronomy (SOFIA). This survey was one of the inaugural Legacy Programs from SOFIA cycle 7, observing a total area of 403 arcmin2 (2180 pc2), including the Sgr A, B, and C complexes. Here we present an overview of the survey strategy, observations, and data reduction as an accompaniment to the initial public release of the survey data. We discuss interesting regions and features within the data, including extended features near the circumnuclear disk, structures in the Arched Filaments and Sickle H ii regions, and signs of embedded star formation in Sgr B2 and Sgr C. We also feature a handful of less well studied mid-infrared sources located between Sgr A and Sgr C that could be sites of relatively isolated star formation activity. Last, we discuss plans for subsequent publications and future data releases from the survey.
Searching for Molecular Outflows with Support Vector Machines: The Dark Cloud Complex in Cygnus

Published: May 2020

We present a survey of molecular outflows across the dark cloud complex in the Cygnus region, based on a 46.75 deg2 field of CO isotopologue data from the Milky Way Imaging Scroll Painting survey. A supervised machine-learning algorithm, the support vector machine, is introduced to accelerate our visual assessment of outflow features in the data cube of 12CO and 13CO J = 1−0 emission. A total of 130 outflow candidates are identified, 77 of which show bipolar structures and 118 are new detections. Spatially, these outflows are located inside dense molecular clouds, and some of them are found in clusters or in elongated linear structures tracing the underlying gas filament morphology. Along the line of sight, 97, 31, and 2 candidates reside in the Local, Perseus, and Outer Arms, respectively. Young stellar objects as outflow drivers are found near most outflows, while 36 candidates show no associated source. The clusters of outflows that we detect are inhomogeneous in their properties; nevertheless, we show that the outflows cannot inject turbulent energy on cloud scales. Instead, at best, they are restricted to affecting the so-called “clump” and “core” scales, and only on short (∼0.3 Myr) estimated timescales. Combined with outflow samples in the literature, our work shows a tight outflow mass–size correlation.
Prediction of the Dst Index with Bagging Ensemble-learning Algorithm

Published: May 2020

The Dst index is a commonly geomagnetic index used to measure the strength of geomagnetic activity. The accurate prediction of the Dst index is one of the main subjects of space weather studies. In this study, we use the Bagging ensemble-learning algorithm, which combines three algorithms—the artificial neural network, support vector regression, and long short-term memory network—to predict the Dst index 1–6 hr in advance. Taking solar wind parameters (including the interplanetary total magnetic field, magnetic field B

z
component, total electric field, solar wind speed, plasma temperature, and proton pressure) as inputs, we establish the Dst index models and complete not only the point prediction but also the interval prediction in forecasting the Dst index. The results show that the root mean square error (rmse) of the point prediction is always lower than 8.0936 nT, the correlation coefficient (R) is always higher than 0.8572 and the accuracy of interval prediction is always higher than 90%, implying that our model can improve the accuracy of point prediction and significantly promote the accuracy of interval prediction. In addition, an new proposed metric shows that the Bagging algorithm brings better stability to the model. Our model was also used to predicate a magnetic storm event from 2016 October 12–17. The most accurate prediction of this storm event is the 1 hr ahead prediction, which holds a result with the rmse of 3.7327 nT, the correlation coefficient of 0.9928, and the interval prediction accuracy of 96.69%. Moreover, we also discuss the balance in the Bagging ensemble model in this paper.
Prospects for the In Situ detection of Comet C/2019 Y4 ATLAS by Solar Orbiter
Authors: Jones Geraint H. , Afghan Qasim , Price Oliver
Published: May 2020

The European Space Agency’s Solar Orbiter spacecraft will pass approximately downstream of the position of comet C/2019 Y4 (ATLAS) in late May and early June 2020. We predict that the spacecraft may encounter the comet’s ion tail around 2020 May 31—June 1, and that the comet’s dust tail may be crossed on 2020 June 6. We outline the solar wind features and dust grain collisions that the spacecraft’s instruments may detect when crossing the comet’s two tails. Solar Orbiter will also pass close to the orbital path of C/2020 F8 (SWAN) on 2020 May 22, but we believe that it is unlikely to detect any material associated with that comet.

Background

This study investigated survival in people living with HIV being followed-up from 5 and 10 years after antiretroviral therapy (ART) initiation in a multi-country Asian cohort.

Methods

We included patients in follow-up >5 years after ART initiation. Factors associated with mortality beyond 5 and 10 years on ART were analysed using competing risk regression with time-updated variables.

Results

Of 13,495 patients retained after 5 years on ART, 279 subsequently died (0.56/100 person-years). Increased mortality was associated with age >50 years (sub-hazard ratio [sHR] 2.24, 95% CI 1.58, 3.15, compared with ≤40 years), HIV exposure through injecting drug use (sHR 2.17, 95% CI 1.32, 3.56), HIV viral load ≥1,000 copies/ml: sHR 1.52, 95% CI 1.05, 2.21, compared with <400), regimen (second-line regimen: sHR 2.11, 95% CI 1.52, 2.94, and third-line regimen: sHR 2.82, 95% CI 2.00, 3.98, compared with first-line regimen), HBV coinfection (sHR 2.23, 95% CI 1.49, 3.33), fasting plasma glucose ≥126 mg/dl (sHR 1.98, 95% CI 1.22, 3.21, compared with <100 mg/dl) and estimated glomerular filtration rate <60 ml/min/1.73 m2 (sHR 2.57, 95% CI 1.56, 4.22). Decreased mortality was associated with transmission through male-to-male sexual contact (sHR 0.44, 95% CI 0.22, 0.88, compared with heterosexual transmission) and higher CD4+ T-cell count (200–349 cells/μl: sHR 0.27, 95% CI 0.20, 0.38, 350–499 cells/μl: sHR 0.10, 95% CI 0.07, 0.16 and ≥500 cells/μl: sHR 0.09, 95% CI 0.06, 0.13, compared with <200 cells/μl). Results after 10 years were similar, but most associations were weaker due to limited power.

Conclusions

Next to preventing ART failure, HIV programmes should carefully monitor and treat comorbidi-ties, including hepatitis, kidney disease and diabetes, to optimize survival after long-term ART exposure.
Troubles du neurodéveloppement : aspects cliniques
Authors: Des Portes Vincent
Published: May 2020

Les troubles du neurodéveloppement ( tnd ) correspondent à un défaut de développement d’une ou plusieurs compétences cognitives attendues lors du développement psychomoteur et socio-affectif de l’enfant, qui entraîne un retentissement important sur le fonctionnement adaptatif scolaire, familial et social. Si chaque tnd présente des spécificités qu’il convient de repérer et prendre en compte, tous les tnd présentent des points communs qui justifient une approche décloisonnée de repérage, diagnostic, interventions et accompagnement personnalisé. Le concept de tnd est scientifiquement et cliniquement pertinent pour les raisons suivantes : plusieurs troubles coexistent souvent chez un même enfant ; certains mécanismes neurobiologiques et génétiques sont communs à plusieurs tnd  ; chez le nourrisson et le petit enfant, plusieurs types de tnd peuvent se présenter sous la forme d’un retard global de développement ; quel que soit le tnd , une intervention précoce est recommandée, fondée sur l’évaluation des souhaits, des compétences, des fragilités et des besoins de soutien de l’enfant ou de l’adulte. Cet article précise le cadre nosographique des tnd , leur prévalence, la démarche de repérage, de diagnostic et d’évaluation fonctionnelle multidimensionnelle, décrit la variété des causes et altérations neurobiologiques structurelles ou fonctionnelles, et esquisse très brièvement les principes d’intervention.
Psychopathologie et troubles neurodéveloppementaux : complémentaires ?
Authors: Ouss Lisa
Published: May 2020

Parler de psychopathologie et de troubles neurodéveloppementaux peut paraître incompatible. Le terme de neurodéveloppement réfère au fait que des troubles mentaux qui émaillent le développement de l’enfant sont le fruit de dysfonctionnements de processus cérébraux, il implique donc une dimension causale. La psychopathologie étudie des conduites humaines pathologiques. Le fossé apparent entre les deux : caractérisation basée sur des principes neuroscientifiques « objectifs », et démarche qui relèverait d’une approximation non basée sur l’évidence, mais sur l’appréciation du clinicien pour l’autre. Ce qui sépare neurodéveloppement et psychopathologie – la démarche diagnostique et la question de la causalité – peut pourtant aussi les rapprocher, pour peu qu’on puisse avoir une démarche de compatibilité et complémentarité. L’approche psychopathologique est non seulement possible, mais indispensable, tant au niveau de l’identification et la caractérisation des tnd , que de leur accompagnement. Deux déclinaisons cliniques illustrent cette position.

Le soutien à l’autodétermination des personnes présentant une déficience intellectuelle constitue un enjeu majeur au cœur des pratiques d’accompagnement. Toutefois, si tous s’accordent sur l’importance de promouvoir ce droit en contexte inclusif, des interrogations demeurent quant aux moyens à utiliser pour contribuer effectivement à l’épanouissement personnel. À la lumière du modèle fonctionnel de l’autodétermination, notre article vise à dresser le portrait de défis posés par le changement de paradigme en vigueur et par la promotion de l’autodétermination en particulier. Notre revue littéraire, critique et réflexive soulève des questionnements que nous étayerons par des pistes de pratiques tirées de nos expériences pédagogiques et scientifiques.
Le trouble déficit d’attention hyperactivité (TDAH) dans les troubles du neurodéveloppement (TND)
Authors: Purper-Ouakil Diane
Published: May 2020

Les troubles du neurodéveloppement ( tnd ) partagent un certain nombre de caractéristiques dont un début précoce et une évolution au long cours, des anomalies de structure et de fonction du développement cérébral et une implication de facteurs génétiques. Cet article propose une approche développementale du trouble déficit d’attention hyperactivité ( tdah) à partir de la clinique illustrée par l’évolution de l’expression des symptômes avec l’âge et à partir des principales données neurobiologiques qui relient le tdah à la catégorie des tnd . Nous ferons un point sur les questions soulevées par d’éventuelles formes à début tardif et finirons par évoquer des enjeux sociaux tels que la stigmatisation et l’auto-stigmatisation liées à ce trouble qu’il faut espérer voir évoluer avec une meilleure connaissance de ses aspects développementaux.
Les échelles de comportement adaptatif Vineland II dans le domaine du neurodéveloppement : les exemples du TSA et du TDAH
Authors: Desquenne Gwendoline , Cappe Émilie
Published: May 2020

Les troubles neurodéveloppementaux sont caractérisés par un déficit, un excès, ou un retard de certains aspects du développement. Ils entraînent une altération du fonctionnement psychique, social et scolaire ou professionnel, en fonction de l’âge de l’individu. Ils s’accompagnent d’une altération des comportements adaptatifs. L’objectif du présent article est de mettre en avant l’importance de leur évaluation dans la population concernée et en particulier l’intérêt des échelles de comportement adaptatif Vineland II au travers des exemples du tsa et du tdah . Quelques échelles d’évaluation des comportements adaptatifs sont présentées afin de mettre en avant l’existence d’une diversité d’outils, avant d’aborder les spécificités de la Vineland II. Cet outil est tout d’abord intéressant par sa validation à la fois en population générale et en population clinique, notamment celle présentant des troubles neurodéveloppementaux. Il est utile pour participer à la démarche de diagnostic et de diagnostic différentiel, ainsi qu’à la mise en place de prises en charge adaptées à la personne et à son trouble spécifique. Par ailleurs, l’adaptabilité de la Vineland II en fait un outil approprié pour une variété de situations importante à la fois aux niveaux individuel et familial. Enfin, au-delà de la personne évaluée elle-même, les proches et les professionnels peuvent bénéficier de la passation qui aide au consensus et à l’élaboration d’une base commune de prise en charge et de compréhension du trouble.
L’autisme, un trouble du neurodéveloppement
Authors: Barthélémy Catherine
Published: May 2020

L’autisme est un trouble du neurodéveloppement qui altère dès les premiers mois de vie de l’enfant ses fonctions de communication sociale et d’adaptation à l’environnement. Grâce à des pratiques cliniques d’observation à l’aide de technologies d’analyse dynamique du comportement du bébé (vidéo, eye-tracking), il est possible de déceler très tôt des anomalies fines des ajustements réciproques chez le bébé autiste. Celles-ci seraient liées à des anomalies, anténatales, du développement et du fonctionnement de base des réseaux nerveux du « cerveau social ». Ces systèmes neuronaux sont, avant l’âge de 4 ans, doués d’une « plasticité » maximale. Le médecin de famille et les professionnels de la petite enfance ont un rôle majeur dans la détection précoce du trouble pour orienter l’enfant et sa famille vers des équipes pluridisciplinaires spécialisées et la mise en route rapide d’un programme d’interventions individualisées, globales et coordonnées.
L’après d’une violation des contrats tacites : une proposition de modèle à partir du cas des pilotes Air France
Authors: Moreau-Grefe Gwenaëlle , Peyrat-Guillard Dominique
Published: May 2020

Les changements économiques qui traversent les organisations bousculent le contenu des contrats psychologiques et sociaux tissés avec les employés. Dans ce contexte, nous proposons d’étudier la rupture et la violation des contrats tacites des membres d’une profession. L’objet de la recherche, qui s’inscrit en comportement organisationnel, est d’éclairer la temporalité des ruptures et des violations entre les différents niveaux de contrats tacites peu étudiés du point de vue de leur articulation. Ce travail prend en compte d’abord les possibilités de contamination ou de protection d’un contrat sur l’autre, puis de recomposition des contrats violés. Ce faisant, l’après d’une violation est interrogé en reliant les formes de prises de parole aux types de recomposition de contrats. Les résultats apportent ainsi une contribution aux travaux de recherche sur le processus de reconstruction post-rupture et violation, reconnus comme embryonnaires dans la littérature. La partie empirique de cette recherche s’appuie sur une étude de cas dans le secteur aérien qui a connu des changements structurels inédits à l’origine d’une nouvelle donne qui bouleverse le contenu des contrats tacites du personnel navigant technique. La grève initiale qui a opposé les pilotes de la compagnie aérienne Air France à sa direction, à partir de l’automne 2014, qualifiée d’historique par la presse, offre le cadre d’une double violation des contrats (psychologiques et social) à partir duquel étudier les suites. L’analyse repose à la fois sur plusieurs corpus documentaires (articles de presse, tracts syndicaux, supports de communication de la Direction à l’intention des pilotes), sur une phase d’observation et sur 35 entretiens conduits auprès de pilotes et managers Air France et permet de développer un modèle intégré post-violations à partir des deux dimensions (la désirabilité et l’activité) nécessaires pour requalifier avec plus de précision la théorie de l’échange social.
Stratégies de gestion des paradoxes de la professionnalisation : le cas d’une association d’aide à domicile
Authors: Ndiaye Adama
Published: May 2020

Les premières associations d’aide à domicile ont été créées dans les années 1940 permettant de rendre visible l’activité domestique, de participer à la reconnaissance des salariés et des emplois du secteur (Puissant, 2012). La forte croissance de l’aide à domicile a toutefois créé de multiples paradoxes témoignant d’un passage de la qualification à la professionnalisation du secteur. Cet article s’intéresse aux stratégies mobilisées par les acteurs d’une association d’aide à domicile pour faire face aux paradoxes de la professionnalisation. À partir d’une étude de cas d’une association d’aide à domicile, nous mobilisons une méthodologie qualitative. Les résultats montrent que le passage d’une qualification à une professionnalisation crée des paradoxes. Les résultats mettent en exergue le rôle majeur joué par les stratégies mobilisées par les acteurs. Toutefois, la mobilisation des stratégies reste fragile puisque qu’au-delà de cette professionnalisation, les acteurs témoignent de contraintes temporelles, physiques et psychologiques. Les résultats permettent d’alimenter la littérature portant sur les paradoxes du social et du médico-social, sur la nature des stratégies développées par les acteurs et sur le rôle des espaces de discussion comme lieu de conversation stratégique.
Psychopharmacological Treatment of Pediatric PTSD
Authors: Naveed Sadiq , Shaik Sabeeha Naazneen , Faquih Amber Ehsan , Kumar Vinod , Motiwala Fatima
Published: May 2020

Early recognition and treatment of posttraumatic stress disorder (PTSD) in youth are critical. This article provides a comprehensive overview of the up-to-date evidence for pharmacological options for children with PTSD. Eight electronic databases were searched and a manual search of the full text of included articles was performed. Two independent reviewers performed screening of the articles using the predetermined eligibility criteria. The data were extracted by two independent reviewers. The search generated 32 articles with a total patient population of 833. The pharmacological options were antidepressants, antipsychotics, mood stabilizers, alpha-adrenergic agents, beta-blockers, serotonin and histamine antagonists, and opioid agonists. The mood stabilizers and second-generation antipsychotics should be reserved for patients with significant safety concerns or aggressive behaviors because of their side-effect profile. Alpha-adrenergic agonists can be used in patients who are re-experiencing symptoms of PTSD and without safety concerns.

Approach to the Diagnosis of Schizoaffective Disorder
Authors: Beckmann David , Schnitzer Kristina , Freudenreich Oliver
Published: May 2020

Diagnosing schizoaffective disorder poses unique challenges due to both its history as a “catch-all” diagnosis and recent changes to the diagnostic criteria. The
Diagnostic and Statistical Manual of Mental Disorder
s, fifth edition, helps to clarify the diagnosis, but issues related to validity and reliability remain. The fundamental approach to diagnosis must be done positively (as opposed to being a diagnosis of exclusion), looking at each feature of a patient's presentation and ensuring that criteria for schizoaffective disorder are met, without symptoms being better explained by a phenomenologically similar yet different psychiatric conditions (and assuming that no medical or toxic condition is responsible). This article presents a straightforward approach to generating and critically assessing a differential diagnosis when schizoaffective disorder is suspected.

Inference in nonparametric/semiparametric moment equality models with shape restrictions
Authors: Zhu Yu
Published: May 2020

This paper studies the inference problem of an infinite‐dimensional parameter with a shape restriction. This parameter is identified by arbitrarily many unconditional moment equalities. The shape restriction leads to a convex restriction set. I propose a test of the shape restriction, which controls size uniformly and applies to both point‐identified and partially identified models. The test can be inverted to construct confidence sets after imposing the shape restriction. Monte Carlo experiments show the finite‐sample properties of this method. In an empirical illustration, I apply the method to ascending auctions held by the US Forest Service and show that imposing shape restrictions can significantly improve inference.
A competing risks model with time‐varying heterogeneity and simultaneous failure
Authors: Liu Ruixuan
Published: May 2020

This paper proposes a new bivariate competing risks model in which both durations are the first passage times of dependent Lévy subordinators with exponential thresholds and multiplicative covariates effects. Our specification extends the mixed proportional hazards model, as it allows for the time‐varying heterogeneity represented by the unobservable Lévy processes and it generates the simultaneous termination of both durations with positive probability. We obtain nonparametric identification of all model primitives given competing risks data. A flexible semiparametric estimation procedure is provided and illustrated through the analysis of a real dataset.
Cluster robust covariance matrix estimation in panel quantile regression with individual fixed effects
Authors: Yoon Jungmo , Galvao Antonio F.
Published: May 2020

This study develops cluster robust inference methods for panel quantile regression (QR) models with individual fixed effects, allowing for temporal correlation within each individual. The conventional QR standard errors can seriously underestimate the uncertainty of estimators and, therefore, overestimate the significance of effects, when outcomes are serially correlated. Thus, we propose a clustered covariance matrix (CCM) estimator to solve this problem. The CCM estimator is an extension of the heteroskedasticity and autocorrelation consistent covariance matrix estimator for QR models with fixed effects. The autocovariance element in the CCM estimator can be substantially biased, due to the incidental parameter problem. Thus, we develop a bias‐correction method for the CCM estimator. We derive an optimal bandwidth formula that minimizes the asymptotic mean squared errors, and propose a data‐driven bandwidth selection rule. We also propose two cluster robust tests, and establish their asymptotic properties. We then illustrate the practical usefulness of the proposed methods using an empirical application.

Published: May 2020

Mathematics is of fundamental importance to any natural sciences program (be-cause it provides analytical and approximate results that can be simulated and modeled) and perhaps to other areas of human knowledge. Ordinary differential equations are especially of fundamental importance to engineering programs be-cause the modeling of all phenomena of interest for these programs involves Or-dinary differential equations solutions; at the same time, students experience diffi-culties when learning Ordinary differential equations and about their applications to real physical scenarios. In this study, the problem-based learning method was used to study a group of mechanical engineering students at the SENAI CIMATEC University Center. The study analyzes the effectiveness of Ordinary differential equations instruction given through this program using the specified methodology. To consolidate the study, Conceptual Field Theory is used together with an evaluation of the results to observe student behaviors and attitudes in re-lation to actions arising from the method. At the end of the study, a questionnaire was completed by the students, with which they evaluated the effectiveness of the teaching methodology employed.
The Attractiveness of Reversing Teaching Forms – Feedback on an Electrical Engineering Course
Authors: Jacques Sébastien , Lequeu Thierry
Published: May 2020

The transformation of teaching practices in universities remains necessary to better motivate, involve and promote the success of increasingly "connected" students. These new practices can be off-putting to teachers because of the complexity of their implementation. New practices, such as those in the in-verted/flipped classroom model, which consists of reversing the nature of in-classroom and out-of-class activities, are well documented in the pedagogical literature; however, few empirical studies are available that allow us to objec-tively analyze their effect on student learning. As such, university teachers are not being encouraged to change their traditional pedagogical practices. This manuscript proposes a rather simple method, which draws on but is not directly equivalent to the inverted classroom model. The aim here is to re-verse the traditional pedagogical sequence of “Lectures; Tutorials; then Prac-tical work”. This mode of teaching is still very popular in the university sys-tem, particularly in France. More precisely, in the proposed model, teaching begins with practical work, followed by tutorials and finishing with lectures that offer time for questions and debates. This method places much more importance on collaborative working and the consolidation of students’ knowledge and skills. An online course platform called Celene has been widely used to support student learning and to maximize teacher-learner in-teractions. The proposed approach was tested with students of an electrical engineering course in their final year of engineering school. A full six-year feedback period is discussed to demonstrate the interactivity and effective-ness of the approach. The results of the various experiments carried out show that this method “smooths” out some of the difference in student competence. In particular, it is a powerful remediation approach to restore energy to students, who sometimes feel overwhelmed by the traditional ap-proach, which is very transmissive. As a result, the proposed method signifi-cantly reduces failure rates.

The positive effect of Sc,Zr-addition on mechanical properties in Al-based alloys preferred for automotive manufacture to produce lightweight vehicles is generally known. Microstructure, mechanical, electrical and thermal properties of the conventionally cast and homogenized (475 °C/60 min) Al-5.4wt.%Zn-3.1wt.%Mg-1.5wt.%Cu (7075) and Al-5.2wt.%Zn-3.0wt.%Mg-1.4wt.%Cu-0.2wt.%Sc-0.1wt.%Zr (7075-ScZr) alloys during isochronal annealing were characterized. Precipitation reactions were studied by microhardness, electrical resistivity and conductivity measurements, differential scanning calorimetry and positron annihilation spectroscopy. Microstructure observation by scanning and transmission electron microscopy proved the Zn,Mg,Cu-containing eutectic phase at grain boundaries in the alloys. The melting of this eutectic phase was observed at ~ 481 °C for the both alloys. The distinct changes in microhardness and electrical resistivity isochronal curves as well as in heat flow of the alloys studied are mainly caused by dissolution of the clusters/Guinier-Preston (GP) zones and by formation of the metastable phase particles of the Al–Zn–Mg–Cu system. Clusters/GP zones were formed during the cooling and/or in the course of the storage at room temperature. These clusters/GP zones were formed predominantly by Mg and Zn alloying elements. Hardening effect after isochronal annealing at temperatures above ~ 300 °C reflects the Sc,Zr-addition in both states of the 7075-ScZr alloy. Probably precipitation of the T-phase (Al2Zn3Mg3) and S-phase (Al2CuMg) particles took place during the annealing. The Sc,Zr-addition does not significantly influence precipitation of the particles formed in the Al–Zn–Mg–Cu system.

Authors: Srirachya Nuttida , Nido Aduena
Published: May 2020

In this study cellulose fibrils were successfully prepared from oil palm leaf stalk fibers by treated with water. The oil palm leaf stalk fibers were treated with water at 80 °C for 8 hours and bleached with 10% NaOCl at room temperature for 2 hours. The treated fibers showed a light-yellow color and had % yield around 76.50 wt.%. The fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA) indicated the removal of lignin and hemicellulose. The FT-IR peaked around 1725 cm-1, that indicated that the peak of lignin and hemicellulose disappeared when the oil palm fibers were treated with water. Moreover, the scanning electron microscope (SEM) micrograph showed a grooved surface due to the removal of lignin and hemicellulose from the outer surface of the oil palm fibers.

Published: May 2020

The porous nanostructured hydroxyapatite (HA) has the high specific surface area and loading capacity that is useful for enhancing bioactivity, sinterability, densification, and the capacity for loading the drug, protein, heavy metals, etc. For the first time, the bipolar membrane in electrochemical method was developed for the synthesis of hydroxyapatite nanosheet-assembled porous structures. The bipolar membrane was installed in the electrolysis cell to separate the cell into two chambers. The bipolar membrane prevented the OH- ions to move away from the cathode chamber and the H+ ions to go to the cathode chamber. In this condition, HA was formed in the cathode chamber while the other calcium phosphate was formed in the anode chamber. The pH increase of solution rapidly leads to more effective the formation of the nanostructured HA. The higher the electrolysis time and the current density the greater the tendency of nanostructured HA formation. The mechanism of HA hydroxyapatite nanosheet-assembled porous structures formation includes the agglomeration formation of the spherical-like particles, the formation of agglomeration nanosheet structures, and the formation of HA hydroxyapatite nanosheet-assembled porous structures.

Published: May 2020

The paper investigates experimentally the usability of ultra-high-strength stainless steel and abrasion resistant steel in laser-welded sandwich structures. The fatigue and shear strength of laser joints were investigated using lap joints that were welded using two very different energy inputs. Also the effect of multiple weld tracks was investigated. The properties of separate laser welds were characterized by hardness testing and optical microscopy. Results of the hardness measurements showed that there was softened area at heat-affected-zone and weld metal of the ultra-high-strength stainless steel welds. AR steels weld metal was harder than base metal and there was softened zone in heat-affected-zone of the weld. The shear strength of tested single weld joints of the ultra-high-strength stainless steel was higher compared abrasion resistant steel single weld joints, but stronger joint can be made with multiple weld seams for abrasion resistant steel. Fatigue strength of investigated ultra-high-strength stainless steel lap joint was lower than fatigue strength of abrasion resistant steel lap joint in the low-cycle regime, but there was no practical difference in fatigue limit (10e7 cycles).

This research focus on catalytic hydrotreating of Jatropha Bio-oil derived fast pyrolysis into biofuel was investigated to determine the effects of the supported type (Al2O3 TiO2 and Al2O3-TiO2 mix-oxide) and of the variables temperature (300-340 °C). The synthesized catalysts were prepared by sol-gel method for support and wet-impregnation with solution promoter on support, and characterization by BET NH3-TPD XRD and NO-TPD for active site analysis of catalysts. The reaction was carried out in a Parr batch reactor under H2 atmosphere about 50 bar for 2 h. The catalytic activity was evaluated for % fatty acid conversion (%FFA), %HDO, %selective to paraffin/olefin products. The results showed that the CMA gave the %FFA is highest, but low selective products, then the CMT gave the % HDO high than CMA, while the mixed-oxide were proving the %HDO, %FFA conversion and % selective is increasing because the TiO2 incorporated with Al2O3 effect to increase the amount of rim site, it’s active site for HYD partway.
