Published: November 2018

La présence de neige et de glaces pérennes dans les gouffres du Moncodeno est connue depuis longtemps, et pourtant aucune étude détaillée ne leur a jusqu'ici été consacrée.

Trois carottes de neige et de glace ont été prélevées dans ces cavités, et des analyses chimiques, isotopiques, cristallographiques ont été menées, ainsi que des études sur leur texture. En croisant ces observations avec les données morphologiques, stratigraphiques et structurelles des accumulations nivo-glaciaires, et avec les enregistrements climatologiques en surface et sous terre, il a été possible de caractériser les processus d'accumulation et de fournir une fourchette (une limite haute et plusieurs limites basses) sur l'âge de ces dépôts. L'échantillon le plus intéressant, prélevé à environ 80 m de profondeur entre deux puits du gouffre "sul margine dell'Alto Bregai" montre, sur plus de 15 m d'épaisseur, une succession de strates de glace transparente. La situation de ce glacier suspendu, éloigné de l'orifice, fait que les chutes de neige ne peuvent l'alimenter. La texture et la cristallographie, associées aux données chimiques et isotopiques, indiquent qu'il s'agit là d'une glace de lac.

Mais on n'observe plus aujourd'hui d'accumulation, et le niveau de la glace a baissé d'au moins trois mètres en 30 ans. Le puits sous-jacent, parfois déglacé dans le passé sous l'action des circulations d'air, draine les eaux de fonte si bien que le lac souterrain ne peut plus se former. L'étude de la stratigraphie et de la glacio-tectonique démontre l'existence d'au minimum trois cycles d'accumulation et d'ablation. Si on les compare aux précipitations locales actuelles et aux évolutions publiées dans la littérature, la composition chimique de la glace et les valeurs du δ180 montrent que cette glace doit être postérieure à la dernière période glaciaire mais a dû précéder les débuts de l'activité industrielle.
Un karst sous la glace de l'Antarctide ?

Are there karstic landforms under Antarctic icecap ?

A new bedrock map of the Dome C area based on all radar data collected during Italian Antarctic Expeditions in 1995, 1997, 1999 and 2001 is presented. The map can clearly distinguish the Dome C plateau, along with some valleys and ridges develop.

The plateau develops at three different altimetric levels and its morphology is characterised by hills and closed depressions. There are no visible features which can be ascribed to glacial erosion or deposition.

The major valley is 15 km wide and 500 m deep ; its axis is parallel to that of other valleys and ridges in the plateau. The valley bottom is not flat, but contains a saddle in its centre. The morphology of the major valley could be considered as a relict one which was not modified by the overlying ice cap. Two big ridges, characterised by hills, saddles and depressions, lie near the boundaries of the area.

The hill and depression landscape may be the result of two different processes : the weathering of granitic rocks, with the development of a "demi-oranges" and inselberg landscape, or the karstification of limestones, and development of a cone karst. The karstic hypothesis should be the more suitable, but it is impossible to exclude the granitic rock wheathering. Both proposed genetic hypotheses call for a warm, humid climate and a long period of stability in a continental environment. Consequently, the ice cap did not largely modify the landscape.

Subterranean mollusks of the karstic network of Padirac (France, Lot) and micro-distribution of Bythinella padiraci Locard, 1903 (Mollusca, Caenogastropoda, Rissooidea).

During a Padirac expedition in November 2003, about ten biological samplings were carried out in the deep karstic network. The first aim of this biospeological mission was to update the data on stygobites mollusks in this subterranean ecosystem. The results show that Bythinella padiraci Locard, 1903, species listed as vulnerable in the 2004 IV CN world Red List of threatened animals, although absent in the upstream part of the Padirac subterranean river, is present in its downstream part after the Déversoir and in the De Joly affluent. An hydrobioid belonging to the genus Islamia was recorded as a component of the stygobiontic biocenose of Padirac as well as Moitessieria rolandiana Bourguignat, 1863. In addition,

3 epigean freshwaters mollusks were observed alive in the deep network, Potamopyrgus antipodarum, Ancylus fluviatilis, Pisidium sp. as well as a terrestrial mollusk, Discus rotundatus.

A la suite des travaux établissant l'âge mésolithique des empreintes de pas humains de l'étage Cathala de la grotte d'Aldène et l'antériorité des fréquentations animales (ours, hyènes) dans ces mêmes galeries [Ambert et al., 2000], les recherches se sont plus spécialement portées sur l'étude sédimentologique et géochronologique (essentiellement par datations isotopiques Uranium/Thorium des concrétions) des remplissages de la cavité. Elles ont notamment précisé l'âge des dernières incursions animales du second étage d'Aldène, entre 41 500 ans B.P. et 25 000 ans B.P. L'analyse détaillée du chaos de blocs interstratifiés de planchers stalagmitiques obstruant l'entrée préhistorique de cette galerie a révélé les modalités et les chronologies de fermeture progressive de cet accès.

Trois phases au moins peuvent être distinguées : deux effondrements de voûte, largement tributaires de l'instabilité lithologique locale, le premier au Pléistocène moyen, le second, et dernier, à l'Holocène ; entre ces deux épisodes, au Pléistocène supérieur, le responsable du colmatage de la galerie principale semble être un apport de cailloutis issus de la gélifraction du porche d'entrée. Les fragments carbonisés de torches ont permis de reconnaître l'ultime et étroit passage emprunté par les hommes du Mésolithique avant le dernier effondrement scellant définitivement cette entrée.
Etat des lieux du tourisme souterrain en France : la fin d'un cycle ?
Authors: Biot Vincent , Gauchon Christophe
Published: November 2018

L'objet de la géographie du tourisme et des loisirs est d'analyser où, comment et pourquoi les activités récréatives s'inscrivent dans l'espace, quelles sont les interrelations entre leurs composants spécifiques et leur milieu d'accueil, naturel et socioéconomique. De ce point de vue, le tourisme souterrain est un bon révélateur des représentations et des pratiques. Après un siècle d'essor souvent spectaculaire qui a mené la France au premier rang des pays européens, le tourisme souterrain paraît aujourd'hui traverser une phase de profond déclin qu'il s'agit ici d'analyser tant dans ses causes, dans ses effets que dans les moyens de stopper ou d'inverser cette évolution. Les théories sur l'invention des sites touristiques et sur les cycles de vie des lieux touristiques sont interrogées pour rendre compte de cette évolution : dans quelle mesure ces modèles théoriques peuvent-ils s'appliquer ici ? Et dans quelle mesure les grottes et les gouffres peuvent-ils aider à la compréhension des dynamiques spatiales du tourisme ?
La sécheresse 2003 et les mesures de température au Trou qui Souffle de Méaudre : rôle du flux géothermique
Authors: Lismonde Baudouin
Published: November 2018

L'équipement d'une galerie profonde du Trou qui Souffle (Vercors, France) permet de suivre en continu, au moyen d'un Luirographe, l'évolution des hauteurs d'eau et des températures : il apparaît ainsi que la sécheresse de 2003 s'est accompagnée d'une montée de 1°C de la température de l'air. L'automne et l'hiver 2003-2004 montrent une chronique de crues d'importance variable accompagnées de baisses des températures. Ces mesures ont permis de mettre en évidence des hétérogénéités thermiques dans le massif, que nous attribuons au flux géothermique. Un modèle théorique, exposé dans un article précédent propose une interprétation des phénomènes observés : c'est la focalisation du flux géothermique qui justifie les fortes vitesses de changement de la température profonde.
Copper(I)-catalyzed tandem reaction: synthesis of 1,4-disubstituted 1,2,3-triazoles from alkyl diacyl peroxides, azidotrimethylsilane, and alkynes
Authors: Israr Muhammad , Ye Changqing , Muhammad Munira Taj , Li Yajun , Bao Hongli
Published: November 2018

A copper-catalyzed azide–alkyne cycloaddition (CuAAC) reaction for the synthesis of 1,4-disubstituted 1,2,3-triazoles from alkyl diacyl peroxides, azidotrimethylsilane, and terminal alkynes is reported. The alkyl carboxylic acids is for the first time being used as the alkyl azide precursors in the form of alkyl diacyl peroxides. This method avoids the necessity to handle organic azides, as they are generated in situ, making this protocol operationally simple. The Cu(I) catalyst not only participates in the alkyl diacyl peroxides decomposition to afford alkyl azides but also catalyzes the subsequent CuAAC reaction to produce the 1,2,3-triazoles.
La physiologie, la table et la modernité : de Brillat-Savarin au « Père Goriot »
Authors: Matsumura Hiroshi
Published: November 2018

Dans cet article, nous allons tenter de repérer les éléments de modernité dans les écrits de notre auteur, ainsi que dans les textes de ses contemporains jusqu’aux années 1830. Cette époque est marquée par un grand bouleversement des habitudes alimentaires, qui se reflète dans divers textes depuis la Physiologie du goût de Brillat-Savarin jusqu’aux premiers écrits journalistiques de Balzac. Dans la scène de banquet de La Peau de chagrin , Balzac représente la restructuration sociale qui caractérise la société d’après 1830. Cette fonction en explique la récurrence dans les romans balzaciens ultérieurs, jusqu’au tableau complet de la société française contemporaine que contient le repas dans Le Père Goriot .
Observation de la « Chronique de Paris » (janvier-juillet 1836)
Authors: Lascar Alex
Published: November 2018

Les lecteurs de Balzac savent quel terrible échec, personnel et financier, fut pour lui la Chronique de Paris . Mais aussi bien la revue elle-même est-elle peu connue, sans être inconnue. On se propose simplement d’examiner avec précision comment on passa de celle de Duckett à celle de Balzac, quels furent ses contenus et ses tendances. Elle fut encyclopédique et pratique, soucieuse d’informer son lecteur avec la plus grande véracité. Journal littéraire, elle sut être exigeante dans ses jugements, en laissant à chacun sa liberté. Et elle fut éclectique, rendant compte aussi bien d’œuvres majeures que d’œuvres mineures. Ce fut encore son honneur de publier non seulement des œuvres de M. de Balzac mais aussi pour finir l’admirable récit de Gautier, La Morte amoureuse . Sa partie politique, malgré son opposition agressive et sans nuances au régime, eut de la tenue. Balzac ne put y traiter de la politique intérieure. Il s’empara de l’« Extérieur » et s’y distingua par le sérieux de son information, la défense de l’alliance russe (et non pas anglaise), et par une mise en texte brillante. Sur un plan général, la politique que prônait réellement la Chronique était moins autocratique que résolument conservatrice et plutôt modérée. Devaient y participer légitimistes fidèles à eux-mêmes et centristes les acceptant comme ils étaient. Elle ne fut agréée ni par les uns ni par les autres. Vrai légitimiste, fondamentalement, Balzac n’était pas un homme de parti. En tout cas en juillet 1836, après un tel fiasco, il n’y a plus pour lui de carrière politique.
The perils of hybridity in 19th-century Java: Ronggawarsita’s reputation, animated debates in Bramartani, and the probable origins of Javanese acrostics; with a postscript on Purwalĕlana
Authors: Ricklefs M.C.
Published: November 2018

n 1866-1867, a controversy in the Javanese newspaper Bramartani raised questions as to whether the writer Ronggawarsita was really a great Javanese pujongga (poet). The correspondents – all from Java’s tiny literate class – stooped to extraordinary rudeness towards each other in the midst of withering criticism of Ronggawarsita, until the newspaper’s editor brought the correspondence to an end. This lively correspondence revealed not only divisions about what, in the new colonial age in Java, constituted good literature, but also about what, in the pages of the new medium of a newspaper, constituted proper manners. It probably also suggests how the Javanese use of acrostics may have found its origins in a popular Dutch song. With Ronggawarsita’s reputation under attack – which occurred again in his final year of life, 1873 – the very different experience of the innovative writer Purwalĕlana is also considered.
Jeux de lumière et zones d’ombre : le droit pénal face aux illégalismes de droits
Authors: Baudrihaye-Gérard Laure , Nagels Carla
Published: November 2018

Les recherches menées sur le traitement particulier réservé par la justice pénale aux illégalismes de droits et à leurs auteurs n’aboutissent pas à des conclusions univoques. Dans cet article, il s’agit d’analyser les ambiguïtés de la réaction pénale et ainsi donner consistance à ce qu’A. Spire et K. Weidenfeld appellent un inconscient d’institution, c’est-à-dire les mécanismes sociaux et institutionnels qui font que le système pénal a du mal à s’en saisir. Pour ce faire, l’article s’appuie sur deux dispositifs méthodologiques. Les entretiens avec des magistrats « financiers » et l’observation au tribunal correctionnel montrent que c’est l’enchevêtrement entre une matière spécifique, des acteurs particuliers et la scène pénale, qui en rend le mieux compte.
Why Are There So Many Different Continuous Improvement Models?
Authors: Galli Brian J.
Published: November 2018

This article examines the implementation of continuous improvement patterns and the various continuous improvement (CI) models used in an organization. Despite the size of an organization, the goal is to achieve the maximum profit by pursuing continuous improvement. There are certain models and theories used in organizations for this reason, which include total quality management, business process re-engineering, Six Sigma, and Lean manufacturing methodology. These models are not only concerned with customer retention and profit maximization, but they are also equally effective for the employee's wellbeing. Different methodologies used in continuous improvement processes will help industrial engineers simplify complex tasks by applying CI tools to different situations. However, the key is to understand what tools and models are appropriate for each application.
Social Media Strategies and Students' Satisfaction at Egyptian Universities
Authors: Easa Nasser Fathi
Published: November 2018

This article aims to investigate the impact of social media strategies on student satisfaction at Egyptian universities. The research employed four social media strategies (the Predictive Practitioner, Creative Experimenter, Social Media Champion and Social Media Transformer). A survey was posted to students Facebook groups in different universities. 530 students from the universities of Alexandria, Tanta Damanhour, Kafrelsheikh, Damietta, and Suez responded to the survey. It was noted that Facebook was the most common social media platform used. The Predictive Practitioner, Creative Experimenter, and Social Media Champion strategies were not clearly implemented, as opposed to the Social Media Transformer. It was noted that there was a lack of satisfaction of students with the information reliability, responsiveness and privacy faculties unusually posted on Facebook. It has been found that the four social media strategies account for positively influencing student satisfaction at Egyptian universities.
The Impact of Customer Churn Factors (CCF) on Customer's Loyalty
Authors: Ahmed Hussein Moselhy Syead
Published: November 2018

This article analyzes the impact of customer churn factors on improving the customer loyalty towards telecommunication service providers in Egypt. To accomplish this, a descriptive method is used. 1500 unique e-mails of customers of telecommunication service providers who have used telecommunication services of these providers were randomly selected. With a 25.6% response rate, the questionnaires were distributed through email and self-administered for data collection. Linear regression analysis was used on the responses. The results showed that there is a statistically significant relationship between customer churn factors and customer loyalty to improve factors and increase loyalty achievement to the telecommunication service providers in Egypt, The implications of the study are that the providers should better manage their relationships with the customers as a competitive policy in the telecommunication service marketplace. It can do that by customer churn management to decrease churn rate and increase customer loyalty.

Published: November 2018

Internet of things is a network of objects mainly supported by electronic devices and electronic components such as sensors and electronic cards. These objects can be physical and virtual devices, sensors or actuators, are autonomous and have their own intelligence characteristics. On the other hand, smart environments are those in which sensors and actuators have been integrated, to react to events and to adapt to those present. The environment acquires intelligence through its intelligent components, or through the intelligence resulting from its interaction with other components. Our contribution is a proposal of Cognitive IoT (CIoT) devices structure by adding an agent layer to the device. Such layer provides the device with agent characteristics (intelligence, autonomy, cooperation and organization).
Overlap Function Based Fuzzified Aquatic Behaviour Information Extracted Tsunami Prediction Model
Authors: Jain Nikita , Virmani Deepali , Abraham Ajith
Published: November 2018

Past natural hazards have produced numerous biological and physical indicators that can be used to predict similar instances in the future. These indicators can be sensed dynamically underwater or on land to generate real time alerts. This article proposes the first validated fuzzified system to predict tsunamis (FABETP) using an overlap-based algorithm. This proposed algorithm can predict seismicity based on underwater marine animal's anomalous behavior, characterized and implemented as biological indicators (i.e., aquatic animal behavioral attributes). Relevant information is extracted from these attributes and used to design fuzzy rules that generate opinion-based alerts. More precisely, the proposed algorithm, Overlap-based Fuzzified rated Marine Behavior, (OBF_MB), derives alert rules when executed on a sea turtle behavior dataset obtained from an online repository. The deployed underwater sensor-collected dataset includes the following measurements: induced electromagnetic field, undersea turtle count, and angle of deviation (in terms of the turtles' navigation direction formulated per month and per day). These values are used as the inputs to the proposed system. To generate an opinion, an information gain-based opinion score is used to calculate the opinion deviations from the generated opinions of the default rule. For future data values, 2004 is used here as the default opinion year and the scenarios is the default rule. This paper formulates three classes of opinions using the proposed algorithm: Alert, Pre-Alert and No-Alert. These opinions can be used in the future to generate real-time alerts based on aquatic animal behavior.
A QoS-Enhanced Model for Inter-Site Backup Operations in Cloud SDN
Authors: AlSous Ammar , Gómez Jorge Marx
Published: November 2018

Data centers backup using a cloud service is a significant operation that saves the data from being lost. It reduces the costs and optimize the hardware provisioning level. Software defined networking (SDN) is a growing network paradigm which divides the usual monolithic control and data plane found in the classical network paradigm. It improves and simplifies the network management process. This research addresses a specific problem in SDNs regarding Quality of Service (QoS) target achievement in backup operations between data centers (inter-site). This fundamental backup activity has special QoS requirements. The aim of this article is to provide a new cost-efficient inter-site backup model for cloud networks using the SDN technique. It helps in choosing a path to perform the backup in the current network according to customer's and provider's requirements, while taking the QoS parameters into consideration simultaneously, in order to achieve an efficient-cost solution.

“There you feel the warmth of foreign life”: Pacifistic Epistolary Novel by Zofka Kveder (1878–1926)
Authors: Samide Irena
Published: November 2018

The present paper addresses the novel Hanka written by Slovene writer Zofka Kveder, published in Croatian in 1917 and translated into Slovene in 1938. The paper shows that this little-known war novel differs substantially from other war narratives and that it can be ranked among the eminent pacifistic literary works of the first two decades of the 20th century. At the same time, the paper questions the role of the texts of Slovenian authors written in a foreign language, and stands up for the view that the national literary sciences should consider the more appropriate placement of these texts in the literary canon.

The Passage from the Oral to the Written Tradition in Récits des hommes libres, Hamadi
Authors: Tomšič Maja
Published: November 2018

The article presents the process of writing and the historical significance of Récits des hommes libres by Hamadi, a collection of Berber traditional tales. Before addressing the characteristics of this collection, we’ll explain a close connection between the Berber literature and its cultural question. The modern Berber literature struggles to preserve its cultural heritage. Furthermore, the Berber tales, as part of a long oral tradition, depend above all on the memory of local storytellers and their audience. When writing down Berber tales, that Hamadi had collected in northern Morocco, he translated them from a Berber language to French. Récits des hommes libres reflect a certain orality, characteristics of the Berber storytelling tradition and Hamadi’s creativity. Thanks to a rich poetic expression, these tales, adapted to our modern times, transmit the emotion probably evoked by the original storytelling in Berber language.
Editing the Translation of Ovid's Metamorphoses by Dr Joža Lovrenčič: New Evidence
Authors: Movrin David
Published: November 2018

Editing the Slovenian translation of Ovid's Metamorphoses by Joža Lovrenčič (1890–1952), left as an unpublished manuscript, has led to the discovery of two original poetry collections by Lovrenčič, which had remained unpublished in the family archives after his death. The first collection, written in 1949, is titled No-one Nothing / in sad songs with a joyful accent / which he was singing about himself in third person / for fun and entertainment / when he went to Parnassus on foot. The other, Brother Honoratus: A Chronicle (1950), is a poetic rendering of a folk story heard by Lovrenčič in prison in August 1945, written in ten chapters. Both collections explore the position of inner exile.
Symbolist Ideas in the Scripts of Gubpolitprosvet
Authors: Braginskaya Nina V.
Published: November 2018

During the period of the so-called Silver age of Russian culture, three outstanding translators of the Greek tragedy, Tadeusz Zieliński, Innokentiy Annensky and Vyacheslav Ivanov, put forward the idea of the third, Slavonic Renaissance – the new rebirth of Antiquity, with the leading role of the Slavic peoples, particularly the Russians. They claimed that while the first Renaissance was Romanesque and the second German (in the era of Winckelmann, Goethe and German classical philology), the third one was supposed to be Slavonic. In the early Soviet period, the idea of Slavonic Renaissance brought about some unexpected results, first of all precisely in the sphere of theater. The paper focuses on how symbolist ideas got to be expressed in the performances of classical tragedies. Ivanov authored the expression “creative self-performance” that later, in the Soviet era, acquired the meaning of “non-professional performance,” such as comedies staged by “sailors and the Red Army soldiers,” Adrian Piotrovsky’s “amateur theatre,” and the pioneer reconstruction of the scenic performance of Aristophanes’ comedies done by Sergey Radlov, Adrian Piotrovsky, and others.

In the Realm of Politics, Nonsense, and the Absurd
Authors: Jensterle-Doležal Alenka
Published: November 2018

The myth of Antigone remained relevant in the twentieth century, and new plays inspired by this myth appeared not only in the West but also in Slavonic drama during and after WW2. Oppressed societies, abuses of power, persecution and execution of political and ideological opponents create a fertile ground for a creative return to the Sophoclean tragedy. Some of the new plays have roots in the trauma of WW2, others in post-war Soviet domination. Significantly, these plays attach growing importance to the character of Creon. Among the discussed playwrights are two Serbs, Jovan Hristić and Oto Bihajli-Merin, two Croats, Marijan Matković and Drago Ivanišević, and the Slovene, Dominik Smole; four Poles, Artur Marya Swinarski, Krystyna Berwińska, Nora Szczepańska, and Roman Brandstaetter; one Slovak, Peter Karvaš, and one Czech, Milan Uhde.

Understanding Aerosol-Cloud-Radiation Interactions Using Local Meteorology and Cloud State Constraints
Authors: Douglas Alyson , L'Ecuyer Tristan
Published: November 2018

Abstract. While many studies have tried to quantify the sign and the magnitude of the warm cloud response to aerosol loading, both remain uncertain owing to the multitude of factors that modulate microphysical and thermodynamic processes within the cloud. Constraining aerosol-cloud interactions using the local meteorology and cloud liquid water may offer a way to account for covarying influences, potentially increasing our confidence in observational estimates of warm cloud indirect effects. Four years of collocated satellite observations from the NASA A-Train constellation, combined with reanalaysis from MERRA-2, are used to partition warm clouds into regimes based on stability, the free atmospheric relative humidity, and liquid water path. Organizing the sizable number of satellite observations into regimes is shown to minimize the covariance between the environment or liquid water path and the indirect effect. Controlling for local meteorology and cloud state mitigates artificial signals and reveals substantial variance in both the sign and magnitude of the cloud radiative response, including regions where clouds become systematically darker with increased aerosol concentration in dry, unstable environments. The reverse Twomey effect, as it has been called, is evident even under the most stringent of constraints, confirming it is not an artificial signal or an isolated phenomenon. These results suggest it is not meaningful to report a single global sensitivity of cloud radiative effect to aerosol. To the contrary, we find the sensitivity can range from −.46 to .11 W m−2ln(AI) regionally.
Geomorphic regulation of floodplain soil organic carbon concentration in watersheds of the Rocky and Cascade Mountains, USA
Authors: Scott Daniel N. , Wohl Ellen E.
Published: November 2018

Abstract. Mountain rivers have the potential to retain OC-rich soil
and store large quantities of organic carbon (OC) in floodplain soils. We
characterize valley bottom morphology, floodplain soil, and vegetation in
two disparate mountain river basins: the Middle Fork Snoqualmie in the
Cascade Mountains and the Big Sandy in the Wind River Range of the Rocky
Mountains. We use this dataset to examine variability in OC concentration
between these basins as well as within them at multiple spatial scales. We
find that although there are some differences between basins, much of the
variability in OC concentration is due to local factors, such as soil
moisture and valley bottom geometry. From this, we conclude that local
factors likely play a dominant role in regulating OC concentration in valley
bottoms and that interbasin differences in climate or vegetation
characteristics may not translate directly into differences in OC storage. We
also use an analysis of OC concentration and soil texture by depth to infer
that OC is input to floodplain soils mainly by decaying vegetation, not
overbank deposition of fine, OC-bearing sediment. Geomorphology and
hydrology play strong roles in determining the spatial distribution of soil
OC in mountain river corridors.
The impact of lightning and radar data assimilation on the performance of very short term rainfall forecast for two case studies in Italy

Published: November 2018

Abstract. In this paper, we study the impact of lightning and radar reflectivity factor data assimilation on the precipitation VSF (Very Short-term Forecast, 3 hours in this study) for two relevant case studies occurred over Italy. The first case refers to a moderate localised rainfall over Central Italy happened on 16 September 2017. The second case, occurred on 09 and 10 September 2017, was very intense and caused damages in several parts of Italy, while nine people died around Livorno, in Tuscany. The first case study was missed by most operational forecasts over Italy, including that performed by the model used in this paper, while the Livorno case was partially predicted by operational models. We use the RAMS@ISAC model (Regional Atmospheric Modelling System at Institute for Atmospheric Sciences and Climate of the Italian National Research Council), whose 3D-Var extension to the assimilation of RADAR reflectivity factor is shown in this paper. Results for the two cases show that the assimilation of lightning and radar reflectivity factor, especially when used together, have a significant and positive impact on the precipitation forecast. The improvement compared to the control model, not assimilating lightning and radar reflectivity factor, is systematic because occurs for all the Very Short-term Forecast (VSF, 3h) of the events considered. For specific time intervals, the data assimilation is of practical importance for Civil Protection purposes because it transforms a missed forecast of intense precipitation (> 40 mm/3h) in a correct forecast. While there is an improvement of the rainfall VSF thanks to the lightning and radar reflectivity factor data assimilation, its impact is reduced by the increase of the false alarms in the forecast assimilating both types of data.
Control of increased sedimentation on orogenic fold-and-thrust belt structure – Insights into the evolution of the Western Alps
Authors: Erdős Zoltán , Huismans Ritske S. , van der Beek Peter
Published: November 2018

Abstract. We use two-dimensional thermo-mechanical models to investigate the potential role of rapid filling of foreland basins in the development of orogenic foreland fold-and-thrust belts. We focus on the extensively studied example of the Western European Alps, where a sudden increase in foreland sedimentation rate is well documented during the mid-Oligocene. Our model results indicate that such an increase in sedimentation rate will temporarily disrupt the formation of an otherwise regular, outward-propagating basement thrust-sheet sequence. The basement thrust active at the time of a sudden increase in sedimentation rate remains active for a longer time and accommodates more shortening than the previous thrusts. As the propagation of deformation into the foreland fold-and-thrust belt is strongly connected to basement deformation, this transient phase appears as a period of slow migration of the distal edge of foreland deformation. The predicted pattern of foreland-basin and thrust-front propagation is strikingly similar to that observed in the North Alpine Foreland Basin and provides an explanation for the coeval mid-Oligocene filling of the Swiss Molasse Basin, due to increased sediment input from the Alpine orogen, and a marked decrease in thrust-front propagation rate. We also compare our results to predictions from critical-taper theory and we conclude, that they are broadly consistent, although, when sedimentation is included, critical-taper theory cannot be used to predict the timing and location of the formation of new basement thrusts. The evolution scenario explored here is common in orogenic foreland basins; hence our results have broad implications for orogenic belts other than the Western Alps.
Facilitating Sustained Attention: Is Mere Presence Sufficient?
Authors: Claypoole Victoria L. , Szalma James L.
Published: November 2018

Research on sustained attention regularly reports declines in task performance as a function of time on task, a phenomenon commonly called the vigilance decrement. Therefore, previous work from theoretical and applied fields has focused on attenuating this performance decrement. Recently, aspects of social facilitation have been used to attain this goal. Social facilitation, or improving task performance through the social presence of an individual, has been found to improve performance on sustained attention tasks. However, the extent to which the forms of social facilitation can mitigate performance are unclear. Thus, the impetus of the present research was to explore the effects of two prevalent forms of social facilitation (i.e., mere presence and evaluative presence) on a sustained attention (i.e., vigilance) task. In sum, 132 observers completed a 24-min cognitive-based vigilance task. The results indicated that an evaluative presence produced the strongest effects on performance, such that the proportion of false alarms was significantly reduced relative to no social presence. Moreover, the mere presence of an individual did not significantly improve vigilance task performance. The results of the present experiment suggest that an evaluative context may be necessary for social presence to improve detection performance on tasks that require sustained attention.

We investigated potential correlations between underlying electroencephalogram (EEG) spectral power and aggressive or nonaggressive antisocial behavior. Frontal and parietal EEG spectral properties were calculated for 3 different ranges (theta, 4–8 Hz; alpha, 8–10.5 Hz; and beta, 10.5–30 Hz) in 900 twins in an open-eyed resting state during 2 stages of development: ages 9–10 and ages 14–15. In multilevel regression modeling, relationships emerged between EEG spectral power properties and measures of antisocial behavior at age 14–15 years but not at the concurrent age of 9–10 years, providing support for neurodevelopmental underpinnings for adolescent-onset antisocial behavior. For boys, frontal alpha power, frontal beta power, and parietal beta power were correlated with aggressive antisocial behavior. For girls, parietal alpha power was anticorrelated with nonaggressive antisocial behavior, raising questions about differing neurobiological profiles for antisocial behavior between sexes. These results also support a distinction between aggressive and nonaggressive antisocial behavior.
Individual Differences and the “Selfish” Connection Between Empathy and Disgust
Authors: White Theresa L. , Cunningham Caitlin , Herz Rachel S.
Published: November 2018

In 2 studies, we investigated the proposition that empathy and disgust are related at a “self”-involved level. In Study 1, 42 undergraduates completed 5 personality questionnaires. Their responses were examined to assess the relationship between dispositional empathy and disgust sensitivity, in contrast to dispositional happiness. Results showed that disgust sensitivity was positively related to a “self-focused” measure of empathy and that in particular, the core disgust and animal reminder subscales of the Disgust Scale—Revised (DS-R) were positively associated with this empathy measure. When the data were examined by sex, all findings became stronger among women and statistically unreliable among men. Study 2 focused on further investigating these findings with 64 female undergraduates. Individual differences in self-focused dimensions of emotional empathy replicated and extended the relationships with the core and animal reminder subscales of the DS-R that were found in Study 1. In both studies some associations between cognitive empathy and happiness were also observed. Our results support the novel proposition that “selfishness” reflects an underlying mechanism through which empathy and disgust are connected and that certain aspects of disgust may involve empathizing with the self.
The Long History of Big Data in Psychology
Authors: Young Jacy L.
Published: November 2018

Big data is a commanding presence in psychology today, yet it also has an extensive history within the discipline. This article outlines shifting frameworks of big data from the earliest years of scientific psychology. From the 1880s, American Psychological Association founder G. Stanley Hall’s extensive undertakings with questionnaires were a key means of collecting mass data. Although these efforts produced descriptive data that were difficult to manage, later innovations in scaled questionnaires by psychologists L. L. Thurstone and Rensis Likert rendered mass data numerical and therefore more amenable to synthesis. In the context of ongoing and ever more massive big data initiatives in psychology, this article raises questions about the historical and current place of the individual in big data.
Studying the Effect of Stakeholders on the Disclosure of Corporate Social Responsibility by Banks: Evidence from Egypt
Authors: El Hawary Engy Mohsen , Arafa Iman Mamdouh
Published: November 2018

Stakeholders have become more attentive to community and social information worldwide. However, their influence on the CSR disclosure is highly contextual and contingent upon several institutional factors. Therefore, this study pursues to identify the stakeholders’ group which has the most powerful effect on the CSR disclosure. The researchers examined the CSR disclosure provided by 38 banks operating in Egypt for the year 2015. Two main indices have been developed; one measures the extent of the CSR disclosure and denoted as as the CSR quantitative index. The other measures the qualitative aspects and denoted as the CSR qualitative index. In addition, five sub-indices have been developed to measure the CSR disclosure as recommened by the GRI. The relationship between these two main indices and the sub-indices and the seven groups of stakeholders have been examined using the OLS regression models. The non-parametric tests are also used to enhance the robustness of our findings and to identify the differences between the stakeholders for each index. Concerning the stakeholder effect, the Egyptian Stock exchange, audit committee and big audit firms are found to have the most powerful impact in our case. On contrary, independent directors, bank’s clients and bank specialty show insignificant results. Generally, the quality and extent of CSR disclosure by the banking sector still undeveloped, particularly for the national banks. Accordingly, the Egyptian Stock Exchange and the Central bank of Egypt need to issue vigorous guidelines and regulations to raise harmonization in the CSR disclosure and to empower their supervisory role in this respect.
Paměťový test učení - recenze metody
Authors: Stehlíková Jolana
Published: November 2018

Paměťový test učení představuje jednu z nejpoužívanějších metod určenou k měření různých aspektů paměti využitelnou v řadě oblastí aplikované psychologie. Tato skutečnost spolu s jednoduchostí a rychlostí administrace PTU patří mezi klady metody.České vydání nicméně trpí některými nedostatky. Předně jsou české normy v manuálu dostupné pouze pro děti ve věku 9-14 let a pro zbylou populaci jsou normy orientační, převzaté ze zahraničí. Tyto normy se liší v mnoha parametrech (věk, pohlaví, množství zahrnutých aspektů testu apod.) a je tedy poměrně obtížné posoudit jejich kvalitu a vybrat normu pro interpretaci výsledků konkrétního probanda. Autor pro tento výběr nezmiňuje žádný postup. Fakt, že již 4 roky existují normy pro českou populaci ve věku 20-85 let zatím v manuálu není reflektován, jelikož od vydání v roce 1999 nedošlo k jeho oficiálnímu přepracování.Další nevýhodou je neuspokojivý popis důkazů o validitě a reliabilitě, které sice lze najít v zahraniční literatuře, nicméně tyto zdroje nemusí být pro běžného uživatele testu dobře dostupné
Le tableau, espace de coconstruction multimodale d’une identité de scripteur chez des élèves allophones
Authors: Azaoui Brahim , Matheu Nathalie
Published: November 2018

À travers l’analyse multimodale d’un rituel quotidien de coécriture mené avec des élèves allophones, ce travail montre comment le support matériel de l’écrit (ici le tableau) peut déclencher et/ou s’inscrire dans un ensemble de représentations de la part des acteurs. L’espace du tableau ainsi que celui situé devant et autour de ce support devient un lieu de mise en scène de soi et de rapport à l’écrit et aux normes. Il est également un espace à territorialiser pour permettre à l’élève d’affirmer, au sein du groupe-classe, son identité d’élève et de scripteur en français.
Rapport à l’écrit et postures de formateurs dans l’accompagnement d’étudiants engagés dans un portfolio certificatif
Authors: Colognesi Stéphane , Célis Sandrine , De Jemeppe Xavier , Van Nieuwenhoven Catherine
Published: November 2018

Notre recherche s’inscrit dans le cadre de l’enseignement universitaire et plus précisément dans le cadre du Certificat d’Aptitude pédagogique approprié à l’Enseignement supérieur (CAPAES) dispensé en Belgique francophone. Il s’agit de tenter de comprendre comment et en quoi le rapport à l’écrit des formateurs universitaires influence la posture d’accompagnement qu’ils proposent à leurs étudiants, que ce soit lors des séminaires consacrés à l’écriture du portfolio certificatif ou lors des entretiens de supervision qu’ils gèrent en face à face avec un étudiant. L’objectif est d’identifier les relations qu’entretiennent les formateurs avec l’écrit(ure) et de voir comment ces relations se traduisent dans l’accompagnement qu’ils proposent aux étudiants. Pour ce faire, la recherche a convoqué plusieurs cadres théoriques dont celui de Leclercq et Oudart (2011) qui ont mis en évidence et documenté trois postures d’accompagnement: normative, dialogique et spéculative. Concernant le champ du rapport à l’écrit, nous nous sommes appuyés sur Blaser (2011) et Barré-de Miniac (2008). La collecte de données s’est réalisée par étapes: entretiens semi-directifs avec les dix accompagnateurs de séminaires, sélection de quatre profils représentatifs de l’ensemble de l’équipe pour un travail complété par l’observation des séminaires, enregistrement d’un entretien de superviseur, lecture de commentaires écrits et interviews finales. Il ressort de l’étude que chaque formateur, inscrit dans un cadre commun, présente des spécificités liées à ses logiques d’accompagnement.
Lorsque l’image parle

Published: November 2018

Cet article retrace l’essence d’une démarche de terrain effectuée dans des contextes principalement autochtones en enseignement des arts. Ce projet a conduit à l’expérimentation en classe de situations d’apprentissage élaborées à partir de capsules numériques réalisées auprès d’artistes autochtones dont la pratique artistique se situe dans le champ de l’art contemporain. L’originalité de ces capsules repose sur l’utilisation du « récit de création » où l’oralité est le moyen pédagogique qui fait naître chez les élèves le désir de créer tout en développant leur estime de soi, leur fierté et leur appartenance identitaires. Un regard critique est également posé sur les enjeux fondamentaux sous-jacents à cette démarche. Ces enjeux découlent de la pertinence d’enseigner les arts afin de pallier l’urgence de la situation sociale liée, non seulement à la question identitaire des jeunes, mais aussi au pouvoir de l’art comme mode de connaissance.
Le cinéma comme fabrique d’images et d’identités
Authors: Bellemare Denis
Published: November 2018

Le travail de l’image et du son agit comme révélateur en termes de relation, de connexion et de transmission culturelle par et au-delà des identités. Les étapes d’archivage et de documentation offrent non seulement un riche potentiel de recherche mais aussi une base perceptive et sensible essentielle à l’atteinte d’une expression visuelle articulée et engagée. La formation en vidéo et cinéma n’est pas une recette ni une simple question de procédés techniques, elle est avant tout un espace relationnel. Filmer engage toute la communauté et est un outil de transmission de savoir et de mémoire comme nous l’expriment les cinéastes autochtones. Cet espace est un entre-lieu saisissant les vues culturelles des participants et ouvrant par la voie de la créativité une pensée visuelle propre aux individus et à leur communauté. Cette créativité se joue autant du côté du formateur que des participants en un continuel processus de participation, de collaboration, de concertation que l’on décrit comme recherche-action par la création.
