Photoluminescence of CdSe/ZnS quantum dots in nematic liquid crystals in electric fields
Authors: Kurochkina Margarita A , Konshina Elena A , Khmelevskaia Daria
Published: May 2018

We have experimentally investigated the effect of the reorientation of a nematic liquid crystal (LC) in an electric field on the photoluminescence (PL) of CdSe/ZnS semiconductor quantum dots (QDs). To the LC with positive dielectric anisotropy, 1 wt % QDs with a core diameter of 5 nm was added. We compared the change of PL intensity and decay times of QDs in LC cells with initially planar or vertically orientated molecules, i.e., in active or passive LC matrices. The PL intensity of the QDs increases four-fold in the active LC matrix and only 1.6-fold in the passive LC matrix without reorientation of the LC molecules. With increasing electric field strength, the quenching of QDs luminescence occurred in the active LC matrix, while the PL intensity did not change in the passive LC matrix. The change in the decay time with increasing electric field strength was similar to the behavior of the PL intensity. The observed buildup in the QDs luminescence can be associated with the transfer of energy from LC molecules to QDs. In a confocal microscope, we observed the increase of particle size and the redistribution of particles in the active LC matrix with the change of the electric field strength. At the same time, no significant changes occurred in the passive LC matrix. With the reorientation of LC molecules from the planar in vertical position in the LC active matrix, quenching of QD luminescence and an increase of the ion current took place simultaneously. The obtained results are interesting for controlling the PL intensity of semiconductor QDs in liquid crystals by the application of electric fields.
Are dispersion corrections accurate outside equilibrium? A case study on benzene
Authors: Gould Tim , Johnson Erin R , Tawfik Sherif Abdulkader
Published: May 2018

Modern approaches to modelling dispersion forces are becoming increasingly accurate, and can predict accurate binding distances and energies. However, it is possible that these successes reflect a fortuitous cancellation of errors at equilibrium. Thus, in this work we investigate whether a selection of modern dispersion methods agree with benchmark calculations across several potential-energy curves of the benzene dimer to determine if they are capable of describing forces and energies outside equilibrium. We find the exchange-hole dipole moment (XDM) model describes most cases with the highest overall agreement with reference data for energies and forces, with many-body dispersion (MBD) and its fractionally ionic (FI) variant performing essentially as well. Popular approaches, such as Grimme-D and van der Waals density functional approximations (vdW-DFAs) underperform on our tests. The meta-GGA M06-L is surprisingly good for a method without explicit dispersion corrections. Some problems with SCAN+rVV10 are uncovered and briefly discussed.
Interferometric Imaging of Titan’s HC3N, H13CCCN, and HCCC15N

We present the first maps of cyanoacetylene isotopologues in Titan’s atmosphere, including H13CCCN and HCCC15N, detected in the 0.9 mm band using the Atacama Large Millimeter/submillimeter array (ALMA) around the time of Titan’s (southern winter) solstice in 2017 May. The first high-resolution map of HC3N in its v
7 = 1 vibrationally excited state is also presented, revealing a unique snapshot of the global HC3N distribution, free from the strong optical depth effects that adversely impact the ground-state (v = 0) map. The HC3N emission is found to be strongly enhanced over Titan’s south pole (by a factor of 5.7 compared to the north pole), consistent with rapid photochemical loss of HC3N from the summer hemisphere combined with production and transport to the winter pole since the 2015 April ALMA observations. The H13CCCN/HCCC15N flux ratio is derived at the southern HC3N peak, and implies an HC3N/HCCC15N ratio of 67 ± 14. This represents a significant enrichment in 15N compared with Titan’s main molecular nitrogen reservoir, which has a 14N/15N ratio of 167, and confirms the importance of photochemistry in determining the nitrogen isotopic ratio in Titan’s organic inventory.

In this Letter, we make use of sophisticated 3D numerical simulations to assess the extent of atmospheric ion and photochemical losses from Mars over time. We demonstrate that the atmospheric ion escape rates were significantly higher (by more than two orders of magnitude) in the past at ∼4 Ga compared to the present-day value owing to the stronger solar wind and higher ultraviolet fluxes from the young Sun. We found that the photochemical loss of atomic hot oxygen dominates over the total ion loss at the current epoch, while the atmospheric ion loss is likely much more important at ancient times. We briefly discuss the ensuing implications of high atmospheric ion escape rates in the context of ancient Mars, and exoplanets with similar atmospheric compositions around young solar-type stars and M-dwarfs.
Dating the Tidal Disruption of Globular Clusters with GAIA Data on Their Stellar Streams
Authors: Bose Sownak , Ginsburg Idan , Loeb Abraham
Published: May 2018

The Gaia mission promises to deliver precision astrometry at an unprecedented level, heralding a new era for discerning the kinematic and spatial coordinates of stars in our Galaxy. Here, we present a new technique for estimating the age of tidally disrupted globular cluster streams using the proper motions and parallaxes of tracer stars. We evolve the collisional dynamics of globular clusters within the evolving potential of a Milky Way-like halo extracted from a cosmological ΛCDM simulation and analyze the resultant streams as they would be observed by Gaia. The simulations sample a variety of globular cluster orbits, and account for stellar evolution and the gravitational influence of the disk of the Milky Way. We show that a characteristic timescale, obtained from the dispersion of the proper motions and parallaxes of stars within the stream, is a good indicator for the time elapsed since the stream has been freely expanding away due to the tidal disruption of the globular cluster. This timescale, in turn, places a lower limit on the age of the cluster. The age can be deduced from astrometry using a modest number of stars, with the error on this estimate depending on the proximity of the stream and the number of tracer stars used.
RIG-I Enhances Interferon-α Response by Promoting Antiviral Protein Expression in Patients with Chronic Hepatitis B
Authors: Wu Shu , Lin Jinpiao , Fu Ya , Ou Qishui
Published: May 2018

Background

Interferon (IFN)-α is widely used for the treatment of chronic hepatitis B (CHB) infection due to the high rate of hepatitis B surface antigen (HBsAg) seroconversion. However, IFN-α treatment has a number of side effects. Thus, identification of molecular biomarkers to predict IFN-α therapeutic effect would be useful in the clinic. In this study, we aimed to investigate the role of retinoic acid-inducible gene-I (RIG-I) in prediction of IFN-α curative effect of CHB patients.

Methods

A total of 65 CHB patients treated with pegylated IFN-α weekly for 48 weeks were enrolled. Realtime PCR was performed for detection of RIG-I and IFN-stimulated gene (ISG) expression. In vitro, the HepG2 cells were transfected with siRNA and levels of RIG-I and anti-HBV proteins were detected by western blot. The P-values were calculated in SPSS 18.0. The statistical significance level was accepted as P<0.05.

Results

In this study, we found RIG-I expression in peripheral blood mononuclear cells was higher in responder than non-responder CHB patients treated with IFN-α therapy. In HBV-transfected HepG2 and Huh7 cells, RIG-I enhanced IFN-α response by promoting anti-HBV protein expression such as double-stranded RNA-dependent protein kinase (PKR), oligoadenylate synthetase (OAS), adenosine deaminase (ADAR1) and Mx protein. Knocking down of RIG-I could downregulate the expression of these proteins. Inhibited RIG-I expression by RIG-I siRNA deceased STAT1 phosphorylation.

Conclusions

Our results revealed RIG-I enhanced IFN-α response by promoting antiviral protein expression via the STAT1 pathway. RIG-I may be a new predictive factor for prediction of IFN-α efficacy in CHB patients.
Checklist of Sphagnum-dwelling testate amoebae in Bulgaria
Authors: Bankov Nikola , Todorov Milcho , Ganeva Anna
Published: May 2018

Until now, a complete checklist of Sphagnum-dwelling testate amoebae in Bulgaria has never been published. Records for species diversity and distribution in the country were scattered in many faunistic and ecological publications. The aim of the present study is to summarise all data for the species distribution at the level of country by reviewing the existing literature and by additional data obtained in our research over the past two years.

The checklist comprises 171 species, classified into 43 genera, 20 families, three orders, three classes and three phyla. We present data for 16 new Sphagnum-dwelling testate amoebae in Bulgaria and new distribution data for 134 species. Of them, 99 species are recorded from Stara Planina Mt., for which there was no available data to date. Additionally are recorded 69 new species for Pirin Mt., 21 for Vitosha Mt. and 18 for Rila Mt. Thirty six species are synonymised according to the latest taxonomic changes. Two misidentified taxa (Euglypha brachiata Penard, 1902 and Difflugia compressa var. africana Gauthier-Lièvre et Thomas, 1958) are transferred into valid species E. acanthophora and Zivkovicia compressa, respectively. Three of the recorded species have not been included in the checklist, because they are currently not refering to testate amoebae (Cochliopodium bilimbosum (Auerbach 1856) and Cochliopodium echinatum Korotneef, 1879 are gymnamoebae (naked amoebae) and Microgromia elegantula (Penard 1904) = Paralieberkuehnia elegantula (Penard 1904) is freshwater foraminifera).
Deep Learning for Forest Species Identification Based on Macroscopic Images
Authors: Mata-Montero Erick , Arias-Aguilar Dagoberto , Figueroa-Mata Geovanni , Valverde Juan Carlos
Published: May 2018

The fast and accurate identification of forest species is critical to support their sustainable management, to combat illegal logging, and ultimately to conserve them. Traditionally, the anatomical identification of forest species is a manual process that requires a human expert with a high level of knowledge to observe and differentiate certain anatomical structures present in a wood sample (Wiedenhoeft (2011)).

In recent years, deep learning techniques have drastically improved the state of the art in many areas such as speech recognition, visual object recognition, and image and music information retrieval, among others (LeCun et al. (2015)). In the context of the automatic identification of plants, these techniques have recently been applied with great success (Carranza-Rojas et al. (2017)) and even mobile apps such as Pl@ntNet have been developed to identify a species from images captured on-the-fly (Joly et al. (2014)). In contrast to conventional machine learning techniques, deep learning techniques extract and learn by themselves the relevant features from large datasets.

One of the main limitations for the application of deep learning techniques to forest species identification is the lack of comprehensive datasets for the training and testing of convolutional neural network (CNN) models. For this work, we used a dataset developed at the Federal University of Parana (UFPR) in Curitiba, Brazil, that comprises 2939 images in JPG format without compression and a resolution of 3.264 x 2.448 pixels. It includes 41 different forest species of the Brazilian flora that were cataloged by the Laboratory of Wood Anatomy at UFPR (Paula Filho et al. (2014)). Due to the lack of comprehensive datasets world wide, this has become a benchmark dataset in previous research (Paula Filho et al. (2014), Hafemann et al. (2014)).

In this work, we propose and demonstrate the power of deep CNNs to identify forest species based on macroscopic images. We use a pre-trained model which is built from the resnet50 model and uses weights pre-trained on ImageNet. We apply fine-tuning by first truncating the top layer (softmax layer) of the pre-trained network and replacing it with a new softmax layer. Then we train again the model with the dataset of macroscopic images of species of the Brazilian flora used in (Hafemann et al. (2014), Paula Filho et al. (2014)).

Using the proposed model we achieve a top-1 98% accuracy which is better than the 95.77% reported in (Hafemann et al. (2014) )using the same data set. In addition, our result is slightly better than the reported in (Paula Filho et al. (2014)) of 97.77% which was obtained by combining several conventional techniques of computer vision.
Best Practices for using Cloud Services for Digital Data Archive and Disaster Recovery
Authors: Gerbracht Jeff , Kelling Steve
Published: May 2018

Managing digital data for long-term archival and disaster recovery is a key component of our collective responsibility in managing digital data and metadata. As more and more data are collected digitally and as the metadata for traditional museum collections becomes both digitized and more comprehensive, the need to ensure that these data are safe and accessible in the long term becomes essential. Unfortunately, disasters do occur and many irreplaceable datasets on biodiversity have been permanently lost. Maintaining a long-term archive and putting in place reliable disaster recovery processes can be prohibitively expensive, both in the cost of hardware and software as well as the costs of personnel to manage and maintain an archival system. Traditionally, storing digital data for the long term and ensuring the data are loss-less, safe and completely recoverable when a disaster occurs has been managed on-premises with a combination of on-site and off-site storage. This requires complex data workflows to ensure that all data are securely and redundantly stored in multiple highly dispersed locations to minimize the threat of data loss due to local or regional disasters. Files are often moved multiple times across operating systems and media types on their way to and from a deep archive, increasing the risk of file integrity issues. With the recent advent of an array of Cloud Services from organizations such as Amazon, Microsoft and Google to more focused offerings from Iron Mountain, Atempo and others, we have a number of options for long term archival of digital data. Deep archive solutions, storage where retrieval expected only in the case of a disaster, are offered by many of these organizations at a rate substantially less than their normal data storage fees.

The most basic requirement for an archival system is storing multiple replicates of the data in geographically isolated locations with a mechanism for guaranteeing file integrity, usually using a checksum algorithm. Additional components that are integral to a robust archive include a simple metadata search and reliable retrieval.

In this presentation, we’ll discuss the need for long term archive and disaster recovery capabilities, detail the current best practices of data archival systems and review a variety of archival options that have become available with Cloud Services.
Two novel species of Neoaquastroma (Parabambusicolaceae, Pleosporales) with their phoma-like asexual morphs
Authors: Phukhamsakda Chayanard , Bhat Darbhe J. , Hongsanan Sinang , Xu Jian-Chu , Stadler Marc , Hyde Kevin D.
Published: May 2018

The monotypic genus Neoaquastroma (Parabambusicolaceae, Pleosporales) was introduced for a microfungus isolated from a collection of dried stems of a dicotyledonous plant in Thailand. In this paper, we introduce two novel species, N.bauhiniae and N.krabiense, in this genus. Their asexual morphs comprise conidiomata with aseptate and hyaline conidia. Neoaquastromabauhiniae has ascomata, asci and ascospores that are smaller than those of N.krabiense. Descriptions and illustrations of N.bauhiniae and N.krabiense are provided and the two species compared with the type species of the genus, N.guttulatum. Evidence for the introduction of the new taxa is also provided from phylogenetic analysis of a combined dataset of partial LSU, SSU, ITS and tef1 sequence data. The phylogenetic analysis revealed a distinct lineage for N.bauhiniae and N.krabiense within the family Parabambusicolaceae.
Mapping the expansion of coyotes (Canis latrans) across North and Central America
Authors: Hody James W. , Kays Roland
Published: May 2018

The geographic distribution of coyotes (Canislatrans) has dramatically expanded since 1900, spreading across much of North America in a period when most other mammal species have been declining. Although this considerable expansion has been well documented at the state/provincial scale, continent-wide descriptions of coyote spread have portrayed conflicting distributions for coyotes prior to the 1900s, with popularly referenced anecdotal accounts showing them restricted to the great plains, and more obscure, but data-rich accounts suggesting they ranged across the arid west. To provide a scientifically credible map of the coyote’s historical range (10,000–300 BP) and describe their range expansion from 1900 to 2016, we synthesized archaeological and fossil records, museum specimens, peer-reviewed reports, and records from wildlife management agencies. Museum specimens confirm that coyotes have been present in the arid west and California throughout the Holocene, well before European colonization. Their range in the late 1800s was undistinguishable from earlier periods, and matched the distribution of non-forest habitat in the region. Coyote expansion began around 1900 as they moved north into taiga forests, east into deciduous forests, west into costal temperate rain forests, and south into tropical rainforests. Forest fragmentation and the extirpation of larger predators probably enabled these expansions. In addition, hybridization with wolves (C.lupus,C.lycaon, and/orC.rufus) and/or domestic dogs has been documented in the east, and suspected in the south. Our detailed account of the original range of coyotes and their subsequent expansion provides the core description of a large scale ecological experiment that can help us better understand the predator-prey interactions, as well as evolution through hybridization.
Le perceur d’enveloppes. De la violence sonore à l’adolescence
Authors: Brault Anthony
Published: May 2018

Par le présent article, l’auteur souhaite mettre en lumière la place et la fonction du sonore et de la musique au sein du processus d’adolescence. Après une discussion théorique de la notion « d’enveloppe sonore » de Didier Anzieu, l’auteur illustre par une articulation théorico-clinique dans quelle mesure l’enveloppe sonore est attaquée au temps de l’adolescence et comment elle peut y résister, tout en se remaniant, grâce à la musique. Enfin l’auteur dresse l’hypothèse selon laquelle l’émergence de l’écoute plurivocale à l’adolescence implique un réaménagement de l’intériorisation du « Groupe Vocal Familial » (E. Lecourt) nécessaire pour que le sujet puisse faire le deuil de ses objets internes parentaux. Cette hypothèse est illustrée par la vignette clinique d’une adolescente de 16 ans inscrite au sein d’un dispositif de « musicothérapie analytique de groupe », permettant ainsi de témoigner d’une proposition thérapeutique face aux achoppements de ces réaménagements pubertaires.
Silence, dynamiques de survie et engagement du travail psychothérapeutique du traumatisme psychique grave dans l’exemple de patients en demande d’asile
Authors: Jan Olivier
Published: May 2018

De nombreux demandeurs d’asile présentent des traumatismes cumulatifs, associant les chocs ayant déterminé leur départ, ceux du voyage et de l’arrivée. Le silence fait partie des défenses prégnantes pour qui a été plongé en dynamique de survie. Le sujet serait inféodé, pour se défendre psychiquement, à l’hypervigilance et la répression, les contenus traumatiques exerçant contre ce rempart une poussée constante. Insistance est faite sur les modalités d’accueil à réserver, sur l’engagement personnel requis, respectant le mutisme des patients mais faisant usage de verbalisations « éclairées » du thérapeute, de ses facultés psychiques et mnémoniques pour contenir, d’une part, et, d’autre part, pour relancer la possibilité de mentalisation, d’abord par l’intellect. Les non-dits des patients sur la souffrance psychique en France sont mentionnés, réserves à faire émerger dans l’optique de plus de liberté d’exister et de penser.
« Entreprise libérée » et sociopsychanalyse. Les obstacles à l’intervention
Authors: Prades Jean-Luc , Escanes Jean-David , Morin Philippe
Published: May 2018

La sociopsychanalyse s’interroge sur les évolutions du contexte de ses interventions. Elle se demande si ces évolutions ne seraient pas en mesure de les empêcher. « L’entreprise libérée », en tant qu’elle représente une nouvelle forme de management, s’imposerait comme objet particulièrement pertinent de cette réflexion. Pour ce faire, ce texte décrit les principales caractéristiques de ce néo-management. Il explicite les conceptions de l’individu et de la liberté et objective les principales caractéristiques de l’ el (entreprise libérée) faisant obstacle à l’introduction d’un Dispositif Institutionnel Mendel ( dim ) en son sein. Les auteurs sont ainsi amenés à interroger l’organisation du travail, la question de l’autorité (et de l’auto-autorité) et à montrer la place prépondérante du leader-libérateur.
Interrogations sur les femmes d’alcooliques : (dé)fondation du couple
Authors: Dudaczyk Delphine , Cloës Claude
Published: May 2018

Ce travail interroge la place occupée par l’alcool au sein du couple conjugal. Contrairement aux idées reçues, les auteurs soutiennent que l’alcool ne constitue pas un facilitateur de rupture du lien mais s’envisage plus comme un intercalaire venant prévenir le couple de la fusion. Pour chacun des membres du couple, l’alcool revêt une fonction dans l’économie psychique et c’est souvent à l’occasion de la séparation conjugale que se révèlent les fantasmes nouant les sujets entre eux. Le récit de la cure de Simone vient souligner que de tels couples peuvent s’instituer à partir du défaut d’élaboration de chaque sujet de la « solitude sereine ». Progressivement, le travail thérapeutique aura pour objet de permettre au sujet de découvrir sa « capacité à être seul », créatrice d’un nouveau lien à l’autre.
La fragmentation du genre dans l’Irak post-invasion
Authors: Ali Zahra
Published: May 2018

Cet article s’intéresse à l’évolution des questions et des mobilisations liées aux femmes et au genre en Irak depuis l’instauration du Code du statut personnel en 1959 et explore l’actuelle fragmentation ethno-confessionnelle des droits des femmes. L’auteure propose de comprendre l’évolution des droits des femmes irakiennes et de leurs conditions de vie en insistant sur l’importance d’adopter une approche complexe, intersectionnelle et historique. Elle se situe ainsi en rupture avec une approche qui se limiterait à analyser la situation des femmes irakiennes à travers un islam indifférencié ou une violence genrée supposée ancestrale. Dans cette perspective, l’article montre que les questions de genre sont imbriquées aux questions d’identité ethnique et confessionnelle, de nationalisme, de religion, à la nature des régimes politiques et aux développements sociaux et économiques qui marquent le pays depuis l’établissement de la République irakienne en 1958. L’auteure examine d’abord les débats et les mobilisations autour des droits juridiques des femmes en Irak. Elle propose ensuite une analyse de la violence politique, économique et militaire qui structure la violence genrée et la définition des normes et des relations de genre depuis les années 1980. Enfin, elle analyse la spécificité de la fragmentation ethno-confessionnelle qui influe sur la vie et les mobilisations des femmes irakiennes depuis 2003.
Déjà papa
Authors: Linou Claire
Published: May 2018

L’haptonomie périnatale amène un couple à rencontrer très tôt son enfant dans le giron de la mère, et l’aide à déployer le lien affectif qui les unit tous les trois. Le père, par sa présence, soutenue par la mère, les inscrit dans une triangulation précoce et ressentie. Dans ces moments tendres, le père accompagne la mère et l’enfant qui développe une sécurité de base. En se familiarisant avec cette approche, en acceptant l’intime de ces rencontres, en développant leur présence, les pères transforment leur manière d’être et, sans en être toujours conscients, se déploient dans leur être-père.
Là où ça peine à avoir un papa, il y a de la peine
Authors: Herbin Andrée
Published: May 2018

Les façons de « faire un enfant » deviennent biotechniques, des formes nouvelles de famille apparaissent. Est-ce pour autant que ce qui fait l’humanité se déliterait ? L’écoute des patients enseigne que la structure est étonnamment préexistante, y compris dans les failles et les manques. Comme un appel possible au père/à la parole. Là où les fonctions paternelle et maternelle peuvent être soutenues par quiconque s’y propose, être un papa demande qu’un homme s’engage concrètement à élever un enfant. S’il n’est pas là, c’est une privation qui demande à être reconnue pour que le chagrin de l’enfant soit consolé et qu’il puisse ensuite, le cas échéant, se laisser adopter par un autre qui le désirerait. La valeur du récit, d’une parole qui prenne acte de la situation réelle, est ici essentielle et redonne à un enfant son histoire singulière.
Représenter ‘V.’ : récit de soi, récit de l’autre, récit d’un « nous »
Authors: Abdelmoumen Mélikah
Published: May 2018

Il y a cinq ans, j’ai rencontré des familles roms de Roumanie vivant dans un bidonville de la région lyonnaise. C’était la première fois que je pénétrais dans un tel endroit (mais c’était loin d’être la dernière), et que je me retrouvais face à des personnes qui vivent dans des conditions aussi inhumaines, tout en étant les victimes d’une discrimination dont je n’avais jamais vu l’équivalent. Je suis écrivaine, et chercheuse. Mon réflexe – tout en nouant des liens avec V., une mère de famille nombreuse, et en tentant d’apprendre à la soutenir de la bonne façon (c’est-à-dire de la façon qui lui convienne, à elle, selon ses choix et ses valeurs) – a été de rendre compte non seulement de ce dont j’étais témoin, mais de ma propre position, moi, gadji, privilégiée (qui pouvais perdre ce privilège du jour au lendemain, comme nous tous), mais également immigrée, et appartenant à un groupe (les « Arabes ») dont la position dans la société française actuelle n’est pas non plus anodine. Ce texte raconte donc le parcours de la femme, de l’immigrée, de la citoyenne et de l’autrice que je suis, en réfléchissant également aux problèmes qu’a pu poser au fil du temps et que pose encore le choix d’écrire au sujet de ces personnes auxquelles je suis personnellement liée, attachée, et de les représenter.
Une ethnographie réciproque
Authors: Gay y Blasco Paloma , de la Cruz Liria
Published: May 2018

La plupart des représentations universitaires des femmes roms sont produites par des non-Roms et, le plus souvent, les vies des premières sont étudiées indépendamment de celles des femmes gadjias. Dans cet article, nous (Liria, vendeuse de rue gitane, et Paloma, anthropologue paya ) discutons notre tentative d’écrire ensemble une histoire de vie réciproque, soit une monographie anthropologique dans laquelle nous explorons nos trajectoires, à la fois très différentes et entrelacées, en tant que femmes espagnoles. Nous analysons notre expérience de rencontre, en tant que collaboratrices et amies, de part et d’autre de lignes de partage à la fois universitaire et ethnique. Dans cette double perspective, nous soulignons des défis que posent à une analyse féministe la vie des femmes roms, en nous interrogeant sur la manière dont elles devraient être représentées dans les textes universitaires, par qui, et avec quelles approches. Nous suggérons qu’un type de collaboration comme celui auquel nous nous sommes essayées dans cet article pourrait servir de modèle pour une coopération universitaire et peut-être même pour une solidarité entre Roms et non-Roms au-delà du monde universitaire.

Accumulation, destruction et hybridation chez Gustave Moreau : rêver pour ou contre l’histoire
Authors: Fauriac Lilie
Published: May 2018

La rémanence du passé visite et tourmente l’œuvre de Gustave Moreau qui est « tatouée » d’une empreinte historique indéniable. Célébré par le xix e  siècle, l’éclectisme des arts est observé activement par le peintre curieux et sensible à « l’air du temps ». Dans un processus d’accumulation, l’artiste réceptionne, fragmente et violente l’histoire et les arts qu’il observe au musée et dans les livres. Dans ses toiles, les histoires se rencontrent et donnent naissance à une vision chimérique inédite. L’abondance ornementale, l’hybridation des mythes, l’étreinte des passés se transforment en des ailleurs qui déforment l’histoire. Cette distorsion semble tout autant étrange que symptomatique d’un siècle marqué par la brutalité des changements politiques et sociaux. Moreau use d’un imaginaire affranchi des limites du présent, préférant ainsi le rêve à son histoire cauchemardesque.
Voir le passé dans les ruines romantiques : une histoire politique et littéraire
Authors: Lyon-Caen Judith
Published: May 2018

Cet article propose une histoire de l’expérience qui consiste à voir et éprouver la présence du passé dans les ruines médiévales mises au goût du jour par les romantiques. Il ne s’agit pas d’une histoire, culturelle, de la diffusion de la « sensibilité romantique », mais d’une enquête sur l’efficace politique de la publication d’images et de textes de littérature aptes à faire voir du passé aux lecteurs du xix e  siècle. De l’entreprise éditoriale lancée sous la Restauration par Charles Nodier et Justin Taylor, les Voyages pittoresques et romantiques dans l’Ancienne France, aux premiers dispositifs touristiques à Jumièges, au début des années 1830, il s’agit de suivre l’effacement d’un usage politico-religieux des ruines sous la Restauration, dont les Voyages portent la trace discrète, au profit d’un usage patrimonial, destiné à traverser le temps.
Normalizing difference: Emotional intelligence and diversity management competence in healthcare managers
Authors: Oyewunmi Adebukola E.
Published: May 2018

Purpose: Diversity is synonymous with difference. The diverse workforce presents an array of complexities which necessitates the deployment of specific managerial competencies. Empirical evidences have indicated the role of emotional intelligence in the enhancement of abilities. Thus, this study investigated the relationship between emotional intelligence and diversity management competency amongst healthcare managers in Southwest Nigeria. Design: The descriptive survey method was adopted for the study. A total of 360 respondents completed the structured questionnaire titled Emotional Intelligence and Diversity Management Competency Questionnaire (EIDMCQ). Data was analyzed using descriptive and inferential statistics such as, Multiple Regression Analyses and Pearson Product Moment Correlation Statistical methods. Findings: A positive correlation was found between emotional intelligence and diversity management competency. Gender, ethnicity, and age, did not moderate the relationship between emotional intelligence and diversity management competency. Practical Implications: As difference is the reality of modern organizations, it is important to conceptualize it as normal and positive. Emotional intelligence is recommended as a critical tool to normalize the individual perceptions of difference. The re-assessment of the functions of managers must be followed by total commitment to capacity building in emotional intelligence, as well as the re-engineering of organizational and national cultures to promote equal opportunities, inclusion and diversity leveraging. Originality/value: This study pioneers research on emotional intelligence and diversity management competency in Nigeria’s public healthcare sector. It conceptualizes diversity management on an individual- managerial level. Practical interventions are provided to enhance the application of specific competencies to optimize a diverse workplace.
Challenges and Opportunities in Vehicular Cloud Computing
Authors: Ahmed Zeinab E. , Saeed Rashid A. , Mukherjee Amitava
Published: May 2018

Vehicular ad-hoc networks (VANET) have become an important research area due to their ability to allow sharing resources among the users to carry out their application and provide services of transport and traffic management. VANET communication allows exchange of sensitive information among nearby vehicles such as condition of weather and road accidents in order to improve vehicle traffic efficiency through Intelligent Transportation Systems (ITS). Many technologies have been developed to enhance ITS. Recently, vehicular cloud computing (VCC) has been developed in order to overcome the drawbacks VANET. VCC technology provides low-cost services to vehicles and capable of managing road traffic efficiently by using the vehicular sources (such as internet) to make decisions and for storage. VCC is considered as the basis for improving and developing intelligent transportation systems.

Vehicular ad hoc networks are relied upon to essentially enhance movement security and transportation productivity. Accessible correspondence, stockpiling, and calculation assets of the associated vehicles are not well used to meet the administration necessities of canny transportation frameworks. Vehicular cloud computing (VCC) is a promising methodology that makes utilization of the preferences of distributed computing and applies them to vehicular systems. Vehicles have turned out to be prepared with different sensors and assets, making them competent to convey, to share assets, and to carry on helpfully. VC can be depicted from the point of view of uses and administrations offered by vehicles that have a place with a vehicular ad hoc network (VANET) due to the impediment of calculation, stockpiling, and data transfer capacity assets for complex in-vehicle sight and sound amusement applications.

Authors: Jinila Y. Bevish , Komathy K.
Published: May 2018

There are rapid technological advancements in the field of transportation. Vehicles cooperate among themselves and establish an intelligent transportation system to fulfill the needs on traffic management. To make this possible, the vehicles are equipped with on board unit which shares information regarding the condition of roads, traffic, and management. Such information is stored in cloud server to be accessed by the vehicles at any time. During the message communication, the origin of the message is checked for its authenticity by the receiver. During signature verification, to preserve the privacy of the user, it is required that the ID of the vehicle should not be revealed. Security and privacy of the information stored in the cloud is a challenging task. The privacy of the vehicle user and the information should be secured from the threats. The solutions in the existing literature do not fulfill the requirements of security and privacy. In this chapter, a secured and dynamic privacy preserving scheme is proposed for vehicular cloud computing. Analysis on the proposed privacy scheme is done based on anonymity and un-linkability. The analysis shows that the proposed dynamic scheme provides better privacy compared to static schemes.

Authors: Poonia Ramesh C. , Raja Linesh
Published: May 2018

In vehicular cloud computing systems (VCC), the overlapping transmission range of each vehicle ensures a unified and common channel for communication among the vehicles. The flexibility of VCC systems opens the door to myriad applications that contribute to the safety and comfort of the passengers. They are distributed, self-organizing communication networks built up by moving vehicles, and are thus characterized by very high node mobility and limited degrees of freedom in mobility patterns. Such particular features often make the standard networking protocol inefficient or unusable, hence the growing effort in the development of communication protocols, which are specific to vehicular networks. Routing protocols should be selected carefully after carrying out literature review. This chapter has investigated different on-demand routing protocols and focused to identify the efficient on-demand routing protocol that can give better performance in realistic environments of vehicular cloud computing systems.
Vehicular Fog Computing Paradigm
Authors: Grover Jyoti
Published: May 2018

The main objective of vehicular ad hoc networks (VANETs) is to improve driver safety and traffic efficiency. Most VANET applications are based on periodic exchange of safety messages between nearby vehicles and between vehicles and nearby road side communication units (e.g., traffic lights, road-side lights, etc.). This periodic communication generates huge amount of data that have typical storage, computation, and communication resources needs. In recent years, there has been huge developments in automotive industry, computing, and communication technologies. This has led to vehicular cloud computing (VCC) as a solution to satisfy the requirements of VANETs such as computing, storage, and networking resources. Vehicular fog computing (VFC) is a standard that comprehends cloud computing and related services to the proximity of a network. Since VANET applications have special mobility, low latency, and location awareness requirements, fog computing plays a significant role in VANET applications and services. In urban cities, vehicles parked at shopping malls, offices and similar other places are under-utilized. These can offer great opportunity and value to implement applications of VFC by utilizing vehicles as an infrastructure. In this chapter, we present real time scenarios and applications of VANET that can be implemented using VFC. VANET applications and quality of service can be enhanced by aggregating the resources of these vehicles. We discuss different types of scenarios of moving and parked vehicles as computational, communication, storage and network infrastructures. We have also discussed the challenges and open problems to implement VFC system. This chapter provides the thorough understanding of novel research paradigm and about vehicular communication infrastructures.
Location-Based Advertising Using Location-Aware Data Mining
Authors: Hu Wen-Chen , Kaabouch Naima , Guo Hongyu , ElSaid AbdElRahman Ahmed
Published: May 2018

This chapter describes how mobile advertisements are critical for both mobile users and businesses as people spend more time on mobile devices than on PCs. However, how to send relevant advertisements and avoid unnecessary ones to specific mobile users is always a challenge. For example, a concert-goer may like to visit restaurants or parks before the concert and may not like the advertisements of grocery stores or farmers' markets. This research tries to overcome the challenge by using the methods of location-aware data mining. Furthermore, privacy is always a great concern for location-based advertising (LBA) users because their location information has to be shared in order to receive the services. This chapter also takes the concern into serious consideration, so the user privacy will not be compromised. Preliminary experiment results show the proposed methods are effective and user-privacy is rigorously preserved.

Published: May 2018

This chapter analyzes the case study of Kanlidere watershed in Cyprus to explore a potential “reintroducing” of the river to its surrounding residential communities (and, on a broader level, to society), in an effective protection and restoration approach of the environment. The Kanlidere (Pedios) is Cyprus' longest river where its watershed has considerable importance for the environmental sustainability of Northern Cyprus. There has been waste, vegetation, and other materials accumulated in the riverbed over many years of neglect, which led to thick vegetation growth and water pooling. This chapter examines the site in order to preserve its overall ecological health, facilitating the improvement of the communities in the future.
The Cycles of Impermanent Alterity in Nazaré
Authors: Silva Cidália Ferreira , Fernandes Marisa Carvalho
Published: May 2018

What happens when a small city expands from 15,000 to 100,000 inhabitants in the summertime? How do temporary inhabitants of Nazaré (Portugal) change the rhythms of its everyday life? How does large-scale tourism change their supporting economic activities or even replace activities such as fishing? Is this seemingly rigid urban fabric elastic enough to expand and adapt to these exponential “others”? The “impermanent alterity” explains the result of the relationship established between land and water, between the “I” and the “other” that come to Nazaré to step onto the warm sand during the summer days. There is a visible cycle of summer-winter change, which the network of lived time interconnections can be found in simple things like the gray pavement line organizing uses, as a device that adapts matter to the cycles of change. Time is the operator of this “impermanent alterity,” and the residents and outsiders alike make it visible.
Ransomware
Authors: Chaurasia Rajashree
Published: May 2018

“Ransomware” is a type of malware that tries to extort money from its victims by hijacking the victim's computer in some way and holding it to ransom. It renders the computer unusable until a ransom amount is paid to the extortionist. And it is very unfortunate that, in many cases, even after the ransom is paid, the victim's computer is not released. Ransomware, as we know it, is gaining popularity at an immense rate among the most notorious cyber-criminals of the world. It isn't just a virus, it's a damned good game plan to becoming a millionaire in a matter of months! This chapter details what ransomware is, how it originated, which families of attacks it falls under, how ransomware is classified, the impact of ransomware on a global scale, the life cycle of a typical ransomware attack, mitigation and containment strategies, trending strains of 2017, and future trends in ransomware attacks. In future, these attack types will dominate our industries and wreak havoc, destroying life and property, if left unchecked.
