We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and PS1 provide multi-band photometry in optical/near-infrared wavelengths over ∼80% of the sky. Our search for satellite galaxies targets ∼25,000 deg2 of the high-Galactic-latitude sky reaching a 10σ point-source depth of ≳22.5 mag in the g and r bands. While satellite galaxy searches have been performed independently on DES and PS1 before, this is the first time that a self-consistent search is performed across both data sets. We do not detect any new high-significance satellite galaxy candidates, recovering the majority of satellites previously detected in surveys of comparable depth. We characterize the sensitivity of our search using a large set of simulated satellites injected into the survey data. We use these simulations to derive both analytic and machine-learning models that accurately predict the detectability of Milky Way satellites as a function of their distance, size, luminosity, and location on the sky. To demonstrate the utility of this observational selection function, we calculate the luminosity function of Milky Way satellite galaxies, assuming that the known population of satellite galaxies is representative of the underlying distribution. We provide access to our observational selection function to facilitate comparisons with cosmological models of galaxy formation and evolution.
A Subsolar Metallicity Progenitor for Cassiopeia A, the Remnant of a Type IIb Supernova

Published: April 2020

We report the detection of the Mn-Kα line in the SN-IIb remnant, Cassiopeia A. Manganese (55Mn after decay of 55Co), a neutron-rich element, together with chromium (52Cr after decay of 52Fe), is mainly synthesized in core-collapse supernovae at the explosive incomplete Si-burning regime. Therefore, the Mn/Cr mass ratio with its neutron excess reflects the neutronization at the relevant burning layer during the explosion. Chandra's deep archival X-ray data of Cassiopeia A indicate a low Mn/Cr mass ratio with values in the range 0.10–0.66, which, when compared to one-dimensional SN explosion models, requires that the electron fraction be 0.4990 ≲ Y
e ≲ 0.5 at the incomplete Si-burning layer. An explosion model assuming a solar-metallicity progenitor with a typical explosion energy (1 × 1051 erg) fails to reproduce such a high electron fraction. We can satisfy the observed Mn/Cr mass ratio if the explosive Si-burning regime was to extend into the O/Ne hydrostatic layer, which has a higher Y
e. This would require an energetic (>2 × 1051 erg) and/or asymmetric explosion of a subsolar-metallicity progenitor (Z ≲ 0.5Z
⊙) for Cassiopeia A. The low initial metallicity can be used to rule out a single-star progenitor, leaving the possibility of a binary progenitor with a compact companion. We discuss the detectability of X-rays from Bondi accretion onto such a compact companion around the explosion site. We also discuss other possible mass-loss scenarios for the progenitor system of Cassiopeia A.

Information on demographic and life-history traits of endangered vertebrate species, such as sea turtles, is crucial for planning management and conservation actions. We applied skeletochronology of phalanges to estimate the age of loggerhead turtles, Caretta caretta, found dead stranded along the beaches of Campania (western Mediterranean) from 2013 to 2017. To obtain maturity data, we examined gonads from a subsample of 7 males and 11 females. Overall, curved carapace length (CCL) ranged from 5.6 to 90.8 cm, but for most turtles (89%) it was 50–79.9 cm. Predominance of stranded females (62%) was recorded. Ten out of the eighteen histologically examined gonads allowed estimating maturity. Based on the lines of arrested growth counting, the estimated age of the examined specimens ranged from 0 (hatchling) to 26 years. The modal age was 14 years for males and 17 years for females. The smallest male with spermatogenetic activity had a CCL of 65 cm and was estimated to be 16 years old. The smallest female with follicular development stage, characterising the transition towards adulthood, had a CCL of 69.5 cm and was estimated to be 20 years old. Anthropogenic factors were responsible for 36% of the mortality of individuals, followed by parasitic/infective pathologies (20%).

Published: April 2020

A new species of green pit vipers of the genus Trimeresurus Lacépède, 1804 is described from the lowlands of western Arunachal Pradesh state of India. The new species, Trimeresurus salazar, is a member of the subgenus Trimeresurus, a relationship deduced contingent on two mitochondrial genes, 16S and ND4, and recovered as sister to Trimeresurus septentrionalis Kramer, 1977. The new species differs from the latter in bearing an orange to reddish stripe running from the lower border of the eye to the posterior part of the head in males, higher number of pterygoid and dentary teeth, and a short, bilobed hemipenis. Description of the new species and T. arunachalensis Captain, Deepak, Pandit, Bhatt & Athreya, 2019 from northeastern India in a span of less than one year highlights the need for dedicated surveys to document biodiversity across northeastern India.
Childhood use of mobile devices: Influence of mothers’ socio-educational level
Authors: Jiménez-Morales Mònika , Montaña Mireia , Medina-Bravo Pilar
Published: April 2020

The presence and variety of mobile devices in Spanish homes, regardless of the social and economic con-text, has been widespread for years. Several studies focus on parental mediation in children's consumption of smart devices, however, there is a lack of scientific evidence about how the educational level and the professional profile of parents affect children’s digital media consumption. This study analyzes the influence of the socio-educational level of families on the consumption of digital screens. The study deepens the understanding on the educational level of parents, as well as their professional category. A quantitative methodology was applied on a sample of 792 primary school children, between 5 and 9 years of age, in three Spanish cities. The consumption of television, smartphones, tablets, computers and videogames was analyzed. Results indicate that, the lower the level of education and professional category of the mother, the greater the consumption of content through smart devices by children. The study demonstrates, there-fore, the importance of considering the educational and professional levels of mothers and fathers for a better understanding of the consumption of digital screens and, at the same time, as an opportunity for designing family strategies that encourage critical thinking and digital media education.

La presencia y la variedad de dispositivos móviles en los hogares españoles, con independencia del contexto social y económico, es una realidad normalizada desde hace años. Diversos estudios se centran en la mediación parental en el consumo infantil de pantallas inteligentes, aunque existe una falta de evidencia científica sobre cómo el nivel de formación y el perfil profesional de las madres y de los padres inciden en las formas de consumo mediático digital de los menores. Este estudio analiza la influencia del nivel socioeducativo de las familias en el consumo de pantallas inteligentes. La investigación profundiza en el nivel de estudios de madres y padres, así como en su categoría profesional. Para ello se utiliza una metodología cuantitativa a partir de una muestra de 792 niños y niñas de primaria, de entre 5 y 9 años, de tres ciudades españolas. Se analiza el consumo de televisión, teléfonos móviles, tabletas, ordenadores y videojuegos. Los resultados señalan que, a menor nivel de estudios y menor categoría profesional de la madre, mayor es el consumo de contenidos a través de dispositivos móviles por parte de los menores. El estudio demuestra la importancia de considerar el nivel educativo y profesional de las madres y de los padres como oportunidad para entender mejor el consumo de pantallas inteligentes y para diseñar estrategias familiares que fomenten el pensamiento crítico y la educación mediática digital.
Karl Löwith et la question de l’anthropologie
Authors: Berner Christian
Published: April 2020

Cette contribution se propose d’étudier l’anthropologie philosophique de Karl Löwith en partant de sa thèse d’habilitation, Das Individuum in der Rolle des Mitmenschen (1928). L’étude de cet ouvrage, dont Löwith nous dit qu’il est « pensé de manière anthropologique », permettra de poser le cadre initial de son anthropologie dont nous montrerons que la visée est éthique. C’est là sans doute, comme nous le montrerons en passant par la lecture de Löwith par Gadamer, que se joue la véritable distanciation avec l’ontologie heideggérienne, même lorsque la pensée de Löwith cherchera à expurger son anthropologie de tout anthropocentrisme.
Schelling et l’architecture
Authors: Galland-Szymkowiak Mildred
Published: April 2020

L’article analyse le sens que prend l’architecture dans la philosophie de Schelling vers 1802/05. On montre comment ce dernier subvertit la thèse de l’architecture-art comme imitation de la simple construction, pour finalement définir l’art architectural par sa capacité à présenter, dans l’inorganique, des allégories de l’organique. On illustre pour finir concrètement différents niveaux de compréhension de cette caractérisation, d’une part avec des exemples tirés de Schelling, d’autre part avec des édifices architecturaux récents relevant à divers titres de la bioinspiration.
Amitié et solidarité
Authors: Gama Luis Eduardo
Published: April 2020

La philosophie herméneutique est présentée en général comme une phénoménologie de la compréhension et une ontologie de l’existence et du langage humains. En cela, son potentiel analytique et critique de la réalité sociale et politique est limité. Néanmoins, certains des textes tardifs de Hans-Georg Gadamer tentent de traduire ces approches ontologiques en réflexions concrètes sur la praxis humaine dans nos sociétés contemporaines. Ils construisent alors les bases d’une véritable philosophie sociale et politique à vocation éminemment critique. À travers les notions d’amitié et de solidarité que l’auteur développe dans ses dernières années, cet article examine ce tournant politique de l’herméneutique.
Sport et handicap psychique
Authors: Bellitto Marc
Published: April 2020

Arthur est autiste et champion valide des Yvelines 2016 en épreuve de durée et en relais 4x400m. Il pratique également de nombreuses autres disciplines en Sport Adapté. Si l’autisme a contribué à façonner son esprit et son corps d’athlète, il constitue aussi un handicap très lourd au quotidien, pour sa pratique sportive comme pour l’ensemble de ses activités. Ce récit, qui débute aux Etats-Unis et se poursuit en France, illustre de quelle manière la pratique sportive a accompagné Arthur dans ses phases de développement, et a véritablement agi en complément des thérapies scolaires, comportementales, et biomédicales. Le projet sportif est même devenu, pour Arthur, synonyme d’une chance supplémentaire d’intégration sociale.

Published: April 2020

La visite à domicile (VAD) est une modalité d’intervention préventive reconnue. La littérature a documenté les meilleures conditions de sa mise en œuvre. Les programmes de VAD recourent fréquemment aux visiteurs para-professionnels. Cependant, peu de recommandations ont été formulées par rapport aux compétences relationnelles, à la formation à la VAD ou à la supervision à apporter à ces intervenants. Cette étude de portée met en avant les principales caractéristiques des interventions recourant à des para-professionnels en VAD. Les résultats portent sur le détail des formations et des supervisions, et mettent en évidence le moindre intérêt porté par les auteurs des interventions sur les compétences interpersonnelles de ces visiteurs à domicile.
Les violences faites aux femmes dans le monde : une pandémie ?
Authors: Dequiré Anne-Françoise
Published: April 2020

Dans le monde, les femmes sont les premières victimes de violences : violences physiques, sexuelles, psychologiques, verbales, économiques. Ces multiples formes de violences ont en commun d’instaurer ou de maintenir une relation de domination, de contrôle, les privant de toute autonomie, niant leurs désirs et leurs droits élémentaires. Cet article se propose de faire un état des lieux des violences faites aux femmes dans le monde, d’en présenter les différentes formes puis d’exposer les causes de ces violences, notamment les causes structurelles et institutionnelles.
Creating rapid test for timely CAN syndrome diagnostics

Published: April 2020

L’objectif de cet article est de faire le point sur le processus de création et de validation d’un test rapide pour quatre formes de base du syndrome CAN (Child Abuse and Neglect, Négligences et abus sur enfants ). La base théorique pour la création du test consiste en une approche intégrée mettant l’accent sur l’approche socio-interactive (Bentowim, 1998 ; Gjuričová, 2000 ; Vlčková, 2001 ; Šramová, 2004 ; Fuchsová, 2009 ; et al. ). Les principales méthodes appliquées lors de la création du test comprenaient l’analyse de contenu de textes spécialisés, la méthode Delphi et la technique du groupe nominal. Les résultats obtenus ont été traités après une application répétée du test dans la pratique. Les résultats des tests ont montré que les groupes de jeunes enfants sont les plus problématiques en termes de diagnostic, que de nombreux enfants testés se trouvent dans le spectre à haut risque, et que les estimations des chercheurs sont beaucoup plus optimistes que la réalité.
Entre respect et non-respect des règles en CHRS : les pratiques des travailleurs sociaux en tension
Authors: Liénard Laure
Published: April 2020

La violence est un fait récurrent dans les centres d’hébergement accueillant des personnes sans domicile fixe. Proscrite par le règlement, elle fait l’objet de sanctions pouvant aller jusqu’à un éloignement, temporaire ou définitif, de l’institution. Ces sanctions sont appréciées en équipe et font jouer de multiples niveaux de valeurs et perceptions ; mais c’est l’adhésion de l’usager et la qualité du lien qui sont évaluées en premier lieu.
Ségrégation résidentielle et mixité sociale dans les quartiers pauvres et stigmatisés en Allemagne, France et Suisse
Authors: Blanc Maurice , Guhl Jutta
Published: April 2020

Le Rhin supérieur est une région européenne à cheval sur l’ Allemagne, la France et la Suisse. Dans le cadre du projet MARGE (2017-2019), financé par le programme de coopération transfrontalière INTERREG V de l’Union européenne, les auteurs ont comparé les politiques de logement des pauvres et des étrangers. Ils soulignent de grandes ambiguïtés qui sont présentes sous des formes un peu différentes : 1. L’accès au logement social est difficile pour les pauvres et les étrangers. Au début, ils passent souvent par le logement privé dégradé. « Le marché de l’insalubre » est très lucratif. 2. Il faut éviter deux types de confusions : d’abord entre mixité sociale (riches et pauvres) et mixité ethnique (nationaux et étrangers) ; ensuite entre mixité spatiale (on réside au même endroit) et mixité sociale (on échange) : la première ne débouche pas toujours sur la seconde et elles peuvent produire des violences, tant institutionnelles qu’interpersonnelles.
Aux origines des Grandes Chroniques de France
Authors: Brix Antoine
Published: April 2020

Cet article propose de refonder l’étude de la fortune littéraire des Grandes Chroniques de France aux xiv e  et xv e  siècles sur des bases nouvelles. Cette histoire des rois de France, l’un des ouvrages français les plus largement diffusés du Moyen Âge, gagne à n’être pas considérée comme un vecteur de la propagande royale en faveur de l’affermissement du sentiment national et de la construction d’un État unitaire. Œuvre née à l’abbaye de Saint-Denis et véhicule d’une vision de l’histoire propre à cette institution, les Grandes Chroniques apparaissent, à l’aune de l’étude d’un échantillon de manuscrits de prestige, supports de réceptions diverses et témoins de lectures parfois critiques, comme un ouvrage dont les rois ne firent jamais la promotion. Aucun exemplaire manuscrit des Grandes Chroniques ne se rencontre d’ailleurs dans les collections royales entre la saisie de la librairie du Louvre et la confiscation des livres de Charles de Bourbon par François I er . Œuvre appréciée des princes et des aristocrates qui s’en transmettaient les copies comme des symboles de leur appartenance sociale et familiale, les Grandes Chroniques ont trouvé des voies de diffusion vers le nord comme vers le sud du royaume. Tant l’élaboration que la diffusion et la réception des Grandes Chroniques sont donc à réécrire, à partir du texte tel qu’il s’est réellement transmis et des manuscrits tels qu’ils ont effectivement été reçus.
Pour en finir avec le despotisme. L’image de Méhémet-Ali dans l’opinion publique franco-britannique
Authors: Figeac Jean-François
Published: April 2020

Méhémet-Ali occupe une place à part entière dans la galerie de portraits des souverains orientaux. Associé au stéréotype orientaliste du despote oriental au début de son gouvernement sur l’Égypte, il fut progressivement représenté comme le modèle de l’homme d’État réformiste influencé par la civilisation européenne. Il fit donc l’objet d’une véritable admiration en France et même dans une partie de la société anglaise. Cette nouvelle image ne se construisit pas ex nihilo mais grâce à une politique d’influence que le vice-roi mena en France et en Angleterre par le biais de son conseiller et médecin Clot-Bey ainsi que par des voyages qu’accomplirent plusieurs jeunes membres de l’élite égyptienne. Son objectif était de pouvoir devenir une alternative crédible au sultan ottoman au cas où celui-ci aurait été renversé par les Russes. Cette stratégie paya au cours de la crise de 1839-1840 qui vit le pacha d’Égypte défier une seconde fois Mahmoud II qui cherchait à récupérer la Syrie. L’opinion publique française défendit dans son immense majorité Méhémet-Ali tandis que la presse anglaise versa dans la francophobie, tout en épargnant le pacha soutenu par la France. Considéré en France comme l’instrument de la revanche contre la coalition qui conduisit au congrès de Vienne, Méhémet-Ali devait rester du point de vue anglais un allié pour pérenniser de la route des Indes. Produit d’une lutte d’influence en Orient, de la mise en place de réseaux pro-égyptiens et de la réception par un public pétri d’orientalisme, la fascination pour Méhémet-Ali nous permet de comprendre les dessous de la rivalité franco-britannique dans cette région du monde, rivalité qui ne trouva une solution qu’avec le percement du canal de Suez.
Liens transnationaux avec la famille élargie africaine dans les familles mixtes en Italie
Authors: Lajus Claire
Published: April 2020

Le maintien des liens avec la famille d’origine représente un enjeu central pour la transmission du sens d’appartenance familiale des enfants lorsqu’un seul des parents est migrant. L’article porte sur les liens intergénérationnels transnationaux entretenus par des familles mixtes en contexte postcolonial. À partir d’une enquête réalisée en Italie entre 2016 et 2017 auprès de couples formés par un parent italien et un parent venu d’Afrique subsaharienne, nous examinons leurs perceptions des liens avec la famille africaine au regard du sens d’appartenance de l’enfant. L’article s’intéresse aux pratiques de maintien des liens, à distance et en présence, ainsi qu’aux contraintes perçues par les parents pour les conserver. L’analyse des résultats met à jour le rôle du contexte migratoire, des conditions économiques, des préjugés et du genre dans les dynamiques familiales.
Les relations intergénérationnelles au sein des familles migrantes. Filiation et affiliation pour les jeunes nés dans le pays d’arrivée
Authors: Dusi Paola , González Falcón Inmaculada
Published: April 2020

Alors qu’assumer les fonctions parentales dans un contexte d’immigration devient toujours plus difficile, les enfants eux doivent se charger du rôle ingrat de réparer la fracture symbolique qui fragilise leur nouvelle identité. Comment les nouvelles générations font-elles face à ce défi ? Quelles formes adopte le rapport parents-enfants ? Quelles perceptions les enfants nés ici de parents migrants ont-ils d’eux-mêmes ? Afin d’examiner ce qu’il advient aux jeunes de ‘seconde génération’ et à leurs familles dans le contexte italien, des entretiens semi-structurés ont été réalisés avec des jeunes nés et élevés ici, par des parents venus d’ailleurs. L’article s’appuie sur l’analyse des données recueillies grâce à 47 entretiens auprès de jeunes de différentes nationalités, âgés de 18 à 30 ans. L’analyse des données s’appuie sur l’approche phénoménologique et le processus de codification ouverte guidé par le principe de la fidélité au phénomène.
Le rôle des oncles et des tantes auprès des familles dont les parents ont présenté des épisodes de négligence. Une étude de cas cliniques
Authors: Maréchal Cindy , Scali Thérèse
Published: April 2020

L’insuffisance et la saturation des services d’aide en matière de négligence parentale sont devenues des préoccupations d’ordre politique. Ainsi, il devient essentiel de pouvoir réactiver les ressources intrafamiliales des familles. L’objectif de cette étude est de mieux comprendre le rôle que les oncles et les tantes peuvent prendre auprès des différents membres du système familial ayant présenté des épisodes de négligence. La présente recherche met en lumière l’expérience de deux familles, à travers l’étude de cas et l’utilisation d’outils cliniques variés (génogramme et FAST). L’analyse des résultats a permis de mettre en évidence le fait que les oncles et/ou tantes qui maintiennent un contact chaleureux avec les parents peuvent être une source de soutien aussi bien pour ces derniers que pour leurs enfants, et agir comme tuteurs de résilience. Cependant, l’étude souligne également un sentiment d’ambivalence des sujets quant à la perception de ce soutien. Différentes hypothèses explicatives sont discutées. La présente recherche contribue ainsi à une meilleure compréhension du soutien des oncles et des tantes et permet de réfléchir sur l’utilité clinique de travailler avec ce sous-système familial.

More than ten million deaths make influenza virus one of the deadliest of history. About half a million sever illnesses are annually reported consequent of influenza. Influenza is a parasite which needs the host cellular machinery to replicate its genome. To reach the host, viral proteins need to interact with the host proteins. Therefore, identification of host-virus protein interaction network (HVIN) is one of the crucial steps in treating viral diseases. Being expensive, time-consuming and laborious of HVIN experimental identification, force the researches to use computational methods instead of experimental ones to obtain a better understanding of HVIN. In this study, several features are extracted from physicochemical properties of amino acids, combined with different centralities of human protein-protein interaction network (HPPIN) to predict protein-protein interactions between human proteins and Alphainfluenzavirus proteins (HI-PPIs). Ensemble learning methods were used to predict such PPIs. Our model reached 0.93 accuracy, 0.91 sensitivity and 0.95 specificity. Moreover, a database including 694522 new PPIs was constructed by prediction results of the model. Further analysis showed that HPPIN centralities, gene ontology semantic similarity and conjoint triad of virus proteins are the most important features to predict HI-PPIs.
Preliminary study on the upcycle of non-structural construction and demolition waste for waste cleaning
Authors: Chen P. , Chen X. , Wang Y. , Wang P.
Published: April 2020

This study proposes a method to convert non-structural calcium-rich construction and demoli­tion waste fines into adsorbents of heavy metal ions by mixing waste fines with diammonium hydrogen phos­phate solution to produce hydroxyapatite, which has high surface areas and excellent ion-exchange capacity with heavy metal ions. As a result, environmental polluting waste is converted into environmentally cleaning material. Waste putty powders was chosen as the representative waste to investigate the detailed formation process of hydroxyapatite and the key reaction parameters of the reaction. Results showed that hydroxyapatite can be pro­duced on waste putty particles. Higher ageing temperatures or longer ageing duration are beneficial to the yield and crystallinity of the produced hydroxyapatite. Adsorption testing confirmed that Ni2+ can replace Ca2+ in the hydroxyapatite lattice, leading to the formation of a new crystal, arupite (Ni3(PO4)2•8H2O), and contributing to a modest adsorption capacity for Ni2+ (15 mg/g) for the hydroxyapatite-containing waste putty.
El romancillo de El bonetero, Juan de Mena y la tradición oral
Authors: Pedrosa José Manuel
Published: April 2020

La fábula de un caballo cojimanco, tropezador y vendido engañosamente a una persona cuya casta social se satiriza, informa unas Coplas de arte menor compuestas por Juan de Mena en el siglo XV y un romancillo hexasílabo documentado en la tradición oral desde el siglo XVII hasta la actualidad. Sus coincidencias formulísticas, argumentales y de intención social sugieren, aunque no prueban definitivamente, su conexión poética. Un epistolario apócrifo del siglo XVII que confunde involuntariamente ambos tipos de textos, el literario y el oral, refuerza también su posible relación poética.

Canciones de boda en la provincia de Guadalajara. Su proceso de creación y la dinámica de cambio
Authors: Lizarazu de Mesa M.ª Asunción
Published: April 2020

A través de una colección concreta de canciones de boda recogidas en la provincia de Guadalajara analizamos la visión del ritual de la boda, de la sociedad que las produce y las admite como propias, y la evolución de su mentalidad, pues son cantos ocasionales que se crean para cada circunstancia específica. Al mismo tiempo se observa la repercusión que los cambios sociales pueden tener en la música. Tanto los textos como los factores que intervienen en las diferentes fases del proceso musical (compositores, intérpretes y audiencia) ponen en evidencia una dinámica de cambio, que, en el caso concreto aquí tratado, consiste en pequeñas modificaciones o variantes tanto textuales como musicales que pueden conducir a cambios de estilo, mientras el repertorio continúa en vigencia, pero también manifiestan cambios más radicales que llegan a sustituir un sistema musical por otro, produciendo la extinción no sólo de repertorios antiguos sino además la transformación del concepto mismo de música y su significación cultural.
COMPUTER-AIDED DIAGNOSTIC SYSTEM FOR FEATURE-BASED CLASSIFICATION USING HEART RATE VARIABILITY
Authors: Tripath Kirti , Sohal Harsh , Jain Shruti
Published: April 2020

This article proposes a computer-aided diagnostic system for feature-based selection classification (CAD-FSC) to detect arrhythmia, atrial fibrillation and normal sinus rhythm. The CAD-FSC methodology encompasses of ECG signal processing phases: ECG pre-processing, R-peak detection, feature extraction, feature selection and ECG classification. Digital filters are used to pre-process the ECG signal and the R-peak is detected by using the Pan-Tompkin’s algorithm. The heart rate variability (HRV) features are extracted in time and frequency domains. Among them, the prominent features are selected with analysis of variance (ANOVA) using Statistical Package for the Social Sciences (SPSS) tool. Cubic support vector machine (C-SVM), coarse Gaussian support vector machine (CG-SVM), cubic k-nearest neighbor (C-kNN) and weighted k-nearest neighbor (W-kNN) classifiers are utilized to validate the CAD-FSC system for three-stage classification. The C-SVM outperforms all other classifiers by giving higher overall accuracy of 98.4% after feature selection of time domain and frequency domain.
MULTIPLE CLASSIFICATION TECHNIQUES TOWARD A ROBUST AND RELIABLE P300 BCI SYSTEM
Authors: Labib Fatma EL-Zahraa M. , Fouad Islam A. , Mabrouk Mai S. , Sharawy Amr A.
Published: April 2020

A brain–computer interface (BCI) can be used for people with severe physical disabilities such as ALS or amyotrophic lateral sclerosis. BCI can allow these individuals to communicate again by creating a new communication channel directly from the brain to an output device. BCI technology can allow paralyzed people to share their intent with others, and thereby demonstrate that direct communication from the brain to the external world is possible and that it might serve useful functions. BCI systems include machine learning algorithms (MLAs). Their performance depends on the feature extraction and classification techniques employed. In this paper, we propose a system to exploit the P300 signal in the brain, a positive deflection in event-related potentials. The P300 signal can be incorporated into a spelling device. There are two benefits behind this kind of research. First of all, this work presents the research status and the advantages of communication via a BCI system, especially the P300 BCI system for disordered people, and the related literature review is presented. Secondly, the paper discusses the performance of different machine learning algorithms. Two different datasets are presented: the first dataset 2004 and the second dataset 2019. A preprocessing step is introduced to the subjects in both datasets first to extract the important features before applying the proposed machine learning methods: linear discriminant analysis (LDA I and LDA II), support vector machine (SVM I, SVM II, SVM III, and SVM IV), linear regression (LREG), Bayesian linear discriminant analysis (BLDA), and twin support vector machine (TSVM). By comparing the performance of the different machine learning systems, in the first dataset it is found that BLDA and SVMIV classifiers yield the highest performance for both subjects “A” and “B”. BLDA yields 98% and 66% for 15th and 5th sequences, respectively, whereas SVMIV yields 98% and 54.4% for 15th and 5th sequences, respectively. While in the second dataset, it is obvious that BLDA classifier yields the highest performance for both subjects “1” and “2”, it achieves 90.115%. The paper summarizes the P300 BCI system for the two introduced datasets. It discusses the proposed system, compares the classification methods performances, and considers some aspects for the future work to be handled. The results show high accuracy and less computational time which makes the system more applicable for online applications.
Disruptive Technology Adoption in Developing Countries
Authors: Budu Joseph
Published: April 2020

The purpose of this study is to explore the factors that inform a consumer's behavioural intention to adopt disruptive information technologies. This study uses an inductive reasoning approach to collect qualitative data which is analysed using interpretive analysis guidelines. The outcome of the analysis is the discovery of three new variables, namely, understanding of technology, meta-price value, and perceived need. The knowledge of technology refers to what a consumer knows about disruptive information technology. The meta-price value refers to a consumer's perception of the benefits to be gained from disruptive information technology as compared to those of the disrupted technology. The perceived need refers to a consumer's realisation of the extent to which disruptive information technology is the sole provider for a fundamental requirement. This study is, arguably, the first to propose a different model to explain the adoption of disruptive information technologies.
Understanding Privacy-Focused Technology Use Among Generation Y
Authors: Agozie Divine Quase , Nat Muesser , Edu Sampson Abeeku
Published: April 2020

This chapter examines privacy-focused technology use among Generation Y cohorts and its impact on their intentions and actual use of social commerce. The study employs a partial least squares SEM to evaluate hypothesized relationships stated. Four hundred eighty-seven responses were used for the analysis. Results show that privacy-focused technology use fails to influence behavioural intentions. By inference, knowledge of privacy risks influences the behavioural intentions of Generation Y, but actual use is impacted where the risk is perceived to be beyond control. This empirical analysis provides insights into key behavioural and technical aspects, offering organizations insights into developing effective social commerce strategies.

Authors: Preko Mansah , Osei-Boateng Richard , Durosinmi Adekunle Ezekiel
Published: April 2020

There is an increasing demand for the healthcare industry in developing economies to reform their existing fragmented paper-based systems to take advantage of the several opportunities that digitalisation brings. However, the existence of specific contextual factors constrains the process of digitalisation in most developing economies. Underpinned by the concepts of installed base and cultivation, this chapter adopts a qualitative multiple-case study approach to examine the contextual factors that influence the development, implementation, and adoption of digital health systems in the Ghanaian and Nigerian contexts. Results of this chapter reveal 13 key challenges and their corresponding mitigating strategies that were adopted in specific instances to facilitate digitalisation in both contexts. A comparison of findings for the two contexts is also discussed.
Resources and Value Co-Creation in Social Commerce
Authors: Entee Edward
Published: April 2020

Social media (SM) is fundamentally changing the way firms conduct business and, in the process, destroying existing business models (BM). Therefore, businesses need to have a BM adaptable to social commerce (SC), which is commerce utilizing social networking services. This viewpoint for future research has questions on the types of SC BM, the value co-created by these models, and the required resources. The study proposes a framework to explore potential BM associated with social media based on their requirements and evaluate the performance of these BM. On the tenets of the study, this viewpoint argues for the need to develop BM for SC and how value is co-created and the resources underpinning this co-creation.
Nanotechnology Safety and Security
Authors: Alba Janette , Roupcova Petra , Klouda Karel
Published: April 2020

Because of their unique characteristics, research and development of new nanomaterials is one of the major disciplines of the twenty-first century, and examining their special properties, especially toxicity, is therefore necessary. As well as their benefits (technological improvements, specific material properties, improved resistance to natural effects), new materials also bring new risks requiring assessment in terms of occupational health and safety and their abuse as potential biological carriers or other materials. The study presents general information about nanoparticles and their distribution and properties in relation to entering aquatic, soil, and atmospheric environments. The study describes and cites examples of measurements conducted on the exposure of different nanomaterials to the work environment. Risk assessments of nanomaterials according to the available methodologies, measures to protect against nanoparticles, and importantly, the abuse of nanoparticles as a potential threat to the CZ population are also described.
Televised Sporting Events
Authors: Marín-Montín Joaquín
Published: April 2020

The second screen has become a new resource for accessing information in addition to what you can see on television. This allows for an enhanced viewing experience through the generation of new services, apps, and changes in the production of content. Sporting events, especially large ones that are broadcast live, have especially developed this innovation. This chapter examines the distinctive features that the second screen contributes to televised sporting events, considering the type of production as well as the effects that are generated in the reception of the content and the alteration to the way the treatment the audiovisual content may receive. To achieve this, real cases from the Spanish context are studied, such as two major cycling events: La Vuelta 2017 (rtve.es) and the Tour de France 2019 (rtve.es and Eurosport Player App).
The Poetics of Videogames
Authors: Navarrete-Cardero Luis
Published: April 2020

The poetic processes that underlie the production of narrative and literary works, film or television screenplays are adapted to transtextual and intertextual logic, which facilitates the transition of the text from its sense to its meaning. All narrative production generates its own sense in the act of linear reading by the reader and/or the spectator. However, the access to the sphere of meaning can only be found in the within the whole of the relationships that a given work maintains with other works that are absent. From this point of view, we propose to apply the logic of the poetics of sense and meaning to the realm of the videogame. Our goal is to prove that such a logic may exist. Yet, videogames have certain rules which regulate their lending and borrowing, thus a legal framework replaces a discursive influence.
Symbolic Consumption in the Online World
Authors: Gordillo-Rodriguez Maria-Teresa , Sanz-Marcos Paloma
Published: April 2020

Symbolic consumption is defined as a process by which people use symbols—products and brands—to construct and communicate ideas about themselves; to transmit identity on the social stage. With this in mind, it is interesting to consider the phenomenon of fashion influencers for a deeper understanding of the concept of symbolic consumption; a phenomenon that has not received the attention it deserves. Fashion influencers share their outfits, purchases and ideas online and they inspire other people to imitate the way they dress and therefore drive the way their followers consume. Influencers participate in symbolic consumption because they select brands that coincide with the images they have of themselves or that they wish to convey to their followers. Fashion influencers offer themselves as sources of inspiration for followers who aspire to be like them by buying and consuming the same brands and products. To support our thesis, we rely on a case study of Chiara Ferragni, who won the number one place on the Forbes list of fashion influencers.
“A Narrative of Impending Tyranny”
Authors: Pineda Antonio , Sánchez-Gutiérrez Bianca
Published: April 2020

Communication and the media count among the means political movements employ in order to influence public opinion. This chapter focuses on the use of internet communication by the Tea Party, a radical movement that re-energized the American right-wing. The authors aim to shed light on the ideological discourse of the Tea Party and its strategic use of online media. The analysis of the Tea Party's discourse is performed in light of the specific ideological tenets and the reactionary narrative that inspire the movement. The study indicates that a consistently “on-message” anti-government libertarianism has found a new outlet on the internet.

GIS and E-Governance for Urban Local Bodies in India
Authors: Mukherjee Falguni
Published: April 2020

Critical GIS recognizes that GIS technology is socially constructed and emphasizes the key role of socio-political and institutional contexts in shaping GIS use. This chapter focuses on the use of GIS for e-governance by urban local bodies (ULB) in the southern state of India and reflects on the status of the project. In recent years the massive proliferation of ICTs in India has led to a transformation from traditional governance to e – governance. Several planning projects have been launched under the rubric of e-governance. The theoretical framework used in this study draws from the Critical GIS body of literature that calls for taking a holistic approach to GIS examination by coupling the internal contexts with the external contextual environment shaping GIS use. To achieve this goal qualitative methods of inquiry are adopted to investigate a GIS based municipal e-governance project initiated by the Government of Karnataka to address issues of urban development.
Enhancing Urban Resilience
Authors: Doyle Aoife , Hynes William , Purcell Stephen M.
Published: April 2020

‘Urban resilience' is a ‘fuzzy' concept which has gained increasing public, political, and academic interest over the past two decades. Yet, despite the increasing ubiquity of the resilience concept, its exact meaning and measurement remains contested. In particular, there remains ongoing debate around how the concept can be operationalised within planning policy and practice This chapter presents updated findings from two EU funded projects - HARMONISE and RESILENS - which both explored the development of e-tools and processes to equip urban planners with capabilities to assess and enhance the resilience of existing and future urban development projects. To date, the widespread development and optimisation of such tools have been relatively limited in practice due to a poor understanding of resilience as a concept, and differing conceptualisations of 'resilience' across borders, disciplines, and professions. This chapter discusses key issues and opportunities in this respect and seeks to chart a pathway forward for more holistic, integrated approaches to urban resilience enhancement.

Authors: Salem Shehab , Fraňa Karel , Nová Iva
Published: April 2020

Nowadays, much effort is directed towards solving the energy crisis resulting from depletion of fossil fuel. This has resulted in new approaches in energy industry like developing new sources of energy and harvesting already wasted energy. One of the commonly wasted forms of energy is the vibrational energy existing in noise produced from daily life activities. The goal of this work is to put a design for an Acoustic Energy Harvesting unit that is based on a Piezo-Electric transducer that can convert sound energy of noise into electric energy. The design process followed an experimental approach. It included open circuit as well as closed circuit experiments. The open circuit experiment aimed at finding a good initial guess for incident sound frequency for optimum energy harvesting while the closed circuit experiment aimed at finding the suitable circuit electrical impedance that would maximise energy harvesting at the frequency obtained from the initial guess. The proposed design can harvest power of 0.043 μW, with voltage of 21 mV and current of 2.05 μA, at power harvesting density of 2.8x . These results are achieved at incident sound of sound pressure level (SPL) of 118 dB and frequency of 466.2 Hz.
