Priming Effect of a Morning Meal on Hepatic Glucose Disposition Later in the Day
Authors: Moore Mary Courtney , Smith Marta S. , Farmer Ben , Kraft Guillaume , Shiota Masakazu , Williams Phillip E. , Cherrington Alan D.
Published: February 2017

We used hepatic balance and tracer ([3H]glucose) techniques to examine the impact of “breakfast” on hepatic glucose metabolism later in the same day. From 0–240 min, 2 groups of conscious dogs (n = 9 dogs/group) received a duodenal infusion of glucose (GLC) or saline (SAL), then were fasted from 240–360 min. Three dogs from each group were euthanized and tissue collected at 360 min. From 360–600 min, the remaining dogs underwent a hyperinsulinemic (4× basal) hyperglycemic clamp (arterial blood glucose 146 ± 2 mg/dL) with portal GLC infusion. The total GLC infusion rate was 14% greater in dogs infused with GLC than in those receiving SAL (AUC360–600min 2,979 ± 296 vs. 2,597 ± 277 mg/kg, respectively). The rates of hepatic glucose uptake (5.8 ± 0.8 vs. 3.2 ± 0.3 mg ⋅ kg−1 ⋅ min−1) and glycogen storage (4.7 ± 0.6 vs. 2.9 ± 0.3 mg ⋅ kg−1 ⋅ min−1) during the clamp were markedly greater in dogs receiving GLC compared with those receiving SAL. Hepatic glycogen content was ∼50% greater, glycogen synthase activity was ∼50% greater, glycogen phosphorylase activity was ∼50% lower, and the amount of phosphorylated glycogen synthase was 34% lower, indicating activation of the enzyme, in dogs receiving GLC compared with those receiving SAL. Thus, morning GLC primed the liver to extract and store more glucose in the presence of hyperinsulinemic hyperglycemia later in the same day, indicating that breakfast enhances the liver’s role in glucose disposal in subsequent same-day meals.
The Effects of Post-Katrina Gasoline Price Regulations: The Contrast between New Brunswick and Nova Scotia
Authors: Erutku Can
Published: February 2017

I test for the effects on retail gasoline prices of a price regulation introduced in Nova Scotia and New Brunswick in July 2006. Using a difference-in-differences empirical model, I find that prices decreased (relative to the control group) only in New Brunswick after the regulation's introduction. Further analysis suggests that prices could also have decreased in Nova Scotia if the regulation in that province had been better designed.
Environmental Policy Convergence in Canada's Fossil Fuel Provinces? Regulatory Streamlining, Impediments, and Drift
Authors: Carter Angela V. , Fraser Gail S. , Zalik Anna
Published: February 2017

This article identifies notable trends in environmental policy surrounding oil and gas development in Canada's leading producing provinces (Alberta, British Columbia, Newfoundland and Labrador, and Saskatchewan) in the period from 2009 to 2014: environmental policy streamlining in particular via the consolidation of environmental policymaking in development-oriented agencies, the continuation and raising of barriers to public involvement in decisions on oil and gas activity, and the avoidance of cumulative impact assessment. These trends signal policy convergence facilitating oil and gas development during a period of accelerating extraction and weakening federal environmental policy. More broadly, this confirms a pattern of conventional politics in energy-dependent subnational governments.
Les armes d’Achille : prolongement de la mémoire héroïque ?
Authors: Perez Isabelle
Published: February 2017

Achilles’s weapons : a prolongation of the memory of the hero ?

Achilles’ fame, archetypal hero of the Greek mythology, is closely linked to its fabulous weapons. Don of the gods, they are the keystone of the heroic identity value for the members of the Greek and Roman elite. The written sources and the figurative directory which put forward these fabulous objects, convey the transmission of the memory of a legendary past on which the Greek and Roman societies lean. The two figurative episodes of the legend which represent weapons on the paintings of Pompeii’s houses are Thetis in forges of Hephaestus and the Discovery to Scyros. This article insists on the reception and symbolism of the Achilles’s weapons, then on the role of the symbolism of the shield in the universe of Roman creation of the first century A. D.
L’antico potere dell’«aurea spada»: da attributo funzionale a personificazione di potenza. Contesti mitopoietici e finalità antropopoietiche di un arma non convenzionale (tra tradizione greca e tradizione mesopotamica)
Authors: Viscardi Giuseppina Paola
Published: February 2017

L’epiteto chrysaoros è generalmente attestato, nell’epica omerica e nell’innografia pseudomerica, per Apollo e Demetra, ma compare anche come attributo di Orfeo in Pindaro e in riferimento a Zeus Chrysaoreus nel culto cario di Stratonicea (antica Chrysaoris). Partendo dall’indagine etimologica dell’aggettivo (composto da chrysos

e aor) e considerati i contesti in cui l’epiteto diventa qualificante, si vuole ricostruire lo specifico valore simbolico e sacrale della corta spada aurea che sembra associare alla funzione sacrificale del coltello il principio di regalità rappresentato dall’oro. Nell’ambito del discorso mitopoietico va altresì tenuto conto che l’aurea spada, menzionata nella forma aggettivale come attributo funzionale del dio, doveva anche evocare nell’immaginario greco arcaico la potenza terrifica personificata dal megas Chrysaor di stirpe titanica noto dalla tradizione cosmogonica esiodea come figlio di Medusa. Come personificazione di potenza, il grande Chrysaor troverebbe peraltro un interessante parallelismo in Šarur, l’arma ipostatica di Ninurta, investita da En-lil del potere di tenere gli occhi aperti sul Kur (la Montagna, la periferia estrema), nel mito sumerico del Lugal-e.
Animali magici e prodigiosi strumenti di caccia: il cane Lailaps e il giavellotto infallibile
Authors: Brancaccio Ida
Published: February 2017

Fra le diverse varianti del mito di Cefalo e Procri elemento costante è la presenza di due strumenti magici, dotati di poteri straordinari : un cane, a cui nessuna preda può sfuggire, e l’infallibile giavellotto, che non manca mai il bersaglio. Sebbene la tradizione antica non sia concorde rispetto alla provenienza di questi «strumenti » di caccia (due le varianti principali : sono proprietà di Minosse re di Creta o della dea Artemide), la dinamica di appropriazione è sempre la stessa : vengono prima donati a Procri e successivamente passano nelle mani di Cefalo. In apparenza si presentano come innocui oggetti di caccia, in realtà in essi è riconoscibile una natura ambigua e contraddittoria che li rende portatori di una forza estremamente sovversiva, capace di minare il rapporto matrimoniale dei due eroi.
Objects of Torture in Hades. A Literary and Iconographic Study
Authors: Painesi Anastasia
Published: February 2017

Greek mythology features a certain number of myths where objects of various natures and origins play an important role as means of torture in Hades. The significance of these objects is indicated by frequent references in ancient texts as well as their iconographic popularity. Sometimes the object of a hybrist’s underworld punishment becomes so legendary that it constitutes a recurrent leitmotiv in ancient authors’ and artists’ repertoire (Oknos’ rope, Ixion’s wheel). The possibility to adapt these myths to the dominant socio-political conditions of various eras (Classical, Hellenistic and Roman) and places (Greece, Italy) resulted in their wide diffusion. The present article aims to determine the origin of myths featuring objects as torture devices. It also seeks to establish the nature of these themes (apotropaic, occult) and their evolution through time. It finally aims to analyse the symbolic meanings with which the objects of torture in Hades were invested in ancient societies.
La rhabdos di Circe. Esegesi di un oggetto magico tra mito e immagine
Authors: Pilo Chiara
Published: February 2017

Nell’Odissea Circe trasforma in maiali i compagni di Odisseo toccandoli con una

rhabdos, termine che designa una verga liscia e flessibile e che nella trasposizione iconografica del mito trova riscontro nel lungo e sottile bastone tenuto in mano dalla dea su alcune raffigurazioni vascolari attiche e sulla Tabula odysseaca «Rondanini » . Attraverso l’esame delle fonti letterarie e iconografiche il presente contributo indaga le valenze di questo oggetto magico che catalizza la potenza di chi lo impugna, proponendone l’accostamento simbolico con il serpente e con l’elemento fallico. Una breve incursione nell’ambito delle fiabe folkloristiche e delle pratiche magiche offre alcuni suggestivi spunti che sembrano supportare questa tesi.
Persée armé de pied en cap : réécritures lyrique et parodique sur la scène française (XVIIe-XVIIIe siècles)
Authors: Beaucé Pauline , Thévenet Lucie
Published: February 2017

Les objets ont une place de taille dans le déroulement narratif des mythes, souvent nourrie par un arrière-plan rituel et symbolique, et leur utilisation se voit revivifiée par la scène de la tragédie lyrique française aux XVIIe-XVIIIe siècle, tout en trouvant une résonance dans les parodies qui foisonnent après chaque représentation. L’exemple du mythe de Persée, dans lequel plusieurs objets sont nécessaires (sandales ailées, bouclier, casque d’invisibilité, épée, besace) est à ce titre éclairant. Après avoir examiné les sources antiques déjà très hétérogènes sur ce point, on étudiera leur réemploi dans l’opéra Persée de Lully / Quinault (1682), ainsi que leur écho dans les parodies : Arlequin Persée, de Louis Fuzelier (1722), Le Mariage en l’air (1737), et Polichinelle Persée, de Denis Carolet (1737). Si l’opéra entame un retour vers une valeur rituelle et symbolique forte des objets, en particulier dans le rapport à la royauté, ce sont paradoxalement les parodistes qui la mettent véritablement en lumière, même sur un mode comique, et ce par une fidélité plus grande aux sources antiques.
De l’Iliade comme accomplissement artistique : poésie et religion
Authors: Aubriot Danièle
Published: February 2017

Considérer l’Iliade sous l’angle de certains procédés poétiques (évolution de l’emploi de quelques termes, nuances dans les variations des comparaisons, récurrence de certaines expressions, utilisation de thèmes conducteurs, échos à travers tout le poème…) amène à mettre en évidence un véritable accomplissement artistique dont la cohérence n’est pas sans résonance théologique.
The First Odysseus: Iliad, Odyssey, and the Ideology of Kingship
Authors: Cairns Douglas l.
Published: February 2017

Apart from the Doloneia in book X, the extended scene in book XI where he is wounded, and the Funeral Games in book XXIII, Odysseus’ major exploits in the Iliad are to be found in books II, XIX, XIV, and XIX, where he functions very largely as a source of perspective on the questionable leadership qualities of Agamemnon (and also, to some extent, on Achilles’ lack of concern for the community to which he belongs). In any discussion of the norms and ideals of leadership in Homer, Odysseus inevitably looms large ; though his role, for much of the poem, is as able advisor and lieutenant, his qualities all shed light on the ideals of leadership and kingship that the poem presents to its audiences. These are ideals that in turn inform both the kingship ideology of the Odyssey and later Greek and Roman responses to Homeric kingship.
Reconsidering ‘Good’ Speakers: Speech-Act Theory, Agamemnon and the Diapeira of Iliad, II
Authors: Christensen Joel P.
Published: February 2017

Nouvelles considérations sur les «bons » orateurs : théorie des actes de langage, Agamemnon et la diapeira du chant II de l’Iliade.

Cet article applique la théorie des actes de langage à la diapeira («le test ») de l’Iliade, II. En mettant l’accent sur le contenu, les intentions déclarées et les divers résultats du test, l’article soutient que, plutôt que dépeindre Agamemnon comme subissant un échec, la scène le décrit en pleine utilisation effective de la rhétorique dans une situation en fin de compte incontrôlable. Au lieu de cela, l’ «échec » de cette scène à répondre aux attentes du public est une invitation à explorer les limites du discours et l’impossibilité de deviner l’intention. Par conséquent, la diapeira est à la fois un exemple de caractérisation complexe et une preuve sophistiquée des difficultés de l’interprétation.
L’oratore dimenticato. Strategie di persuasione nell’Odissea
Authors: Dentice di Accadia Ammone Stefano
Published: February 2017

The Forgotten Speaker. Strategies of Persuasions in the Odyssey.

Ancient critics recognised in the society represented in the Homeric poems the presence of a well consolidated rhetorical practice. Modern commentators of the Iliad and the Odyssey have in reverse shown little attention to this topic. In this paper I will examine the strategies of persuasion in some of the speeches of Ulysses in the Odyssey. From my analysis it will be evident that the Poet had a good degree of consciousness of rhetorical devices, which were used in order to persuade someone of an idea or an action. Homer sometimes even reflected upon the effects of the spoken word and thus outlined an ante litteram rhetoric.
Imagination versus Necessity in the Homeric Hymn to Apollo
Authors: Heiden Bruce
Published: February 2017

The Homeric Hymn to Apollo presents the Olympians as thinking agents who transform material facts by imagining future projects. Each tale narrates how Olympian planning enabled naturally impoverished places to become wealthy and honored mortal communities. The hymnist’s descriptions of festivities at Delos and on Olympus illustrate how the naturally determined aspects of mortal existence are ameliorated by the Muses’ gift of wisdom. The hymn’s tales of Olympian projects and actions in the past offer mortals a pedagogy in imagination and planning the future.
L’énigme de Calchas : un étonnement fatal (Hésiode, fragment 278 M-W )
Authors: Hunzinger Christine
Published: February 2017

Calchas’ Riddle : A Wonder that Proved to be Fatal (Hesiod, Fragment 278 M-W). This article deals with the Hesiodic fragment narrating Calchas’ death. Parallels between the mantic contest of Calchas and Mopsos and the traditional form of the riddle contest are first developed. The function of wonder (θαῦμα) in the contest is then analysed, a fatal wonder which coheres with the Hesiodic representation of θαῦμα.
Pindar’s Other Sources: Catalogue and Advice Poetry
Authors: Hernández Pura Nieto
Published: February 2017

Les autres sources de Pindare – la poésie de catalogue et d’admonition.

Cet article examine les points de rencontre entre la mythologie et la mythographie dans la poésie grecque archaïque en prenant la Neuvième Pythique de Pindare comme cas d’étude. La poésie de Pindare a des liens particuliers avec des traditions quasi mythographiques, comme la poésie de catalogue et d’admonition, représentées ici par le Catalogue des Femmes et les Leçons de Chiron du pseudo-Hésiode. La façon dont Pindare choisit, reprend et systématise les matériaux qui lui conviennent opère de façon assez proche de celle que l’on trouve dans les oeuvres des mythographes postérieurs, même si les oeuvres finales ont des projets et des effets très différents.

Published: February 2017

“ Hector Killer of Men” or “ Hector Tamer of Horses” : Formulaic Artistry and Narrative in the Iliad.

The coexistence of Ἕκτορος ἀνδροφόνοιο / Ἕκτορος ἱπποδάμοιο, two equivalent formulas, is generally considered as a breach in the economy of the formulaic system. The study of the two epithets’ distribution within the Iliad reveals their role in the characterization of Hector and the narrative function of the pair they are forming, for it is closely linked to the evolution of Hector’s and Achilles’ relationship.
L’anthropologie homérique au cœur de la polémique anti-chrysippéenne dans le De placitis Hippocratis et Platonis de Galien
Authors: Lacore Michelle
Published: February 2017

Homeric Anthropology at the Core of Galen’s anti-Chrysippean Polemic in the De placitis Hippocratis et Platonis.

With a view to both disproving the Chrysippean unitarian rationalistic anthropology and demonstrating the validity of the Hippocratic and Platonician tripartition of the soul into rational, spirited and desiderative part, with a specific bodily organ where each of them belongs, Galen points out how Chrysippus abusively quotes poetic examples especially the Homeric ones he uses instead of conclusive proofs, piling them up among inconsistencies. Galen sets against that disreputable method the Platonic one in which poetic examples are found only after a rigourous demonstration has been achieved. Galen’s personal quotations are mainly aimed at challenging the Stoicians by means of medical exegesis, according to which the Homeric myth of Tityos foreshadows the liver’s psychological function, as lust’s seat.
Aidôs. Ce qu’Homère apprend au philosophe contemporain
Authors: Wersinger Anne Gabrièle
Published: February 2017

Aidôs. What Homer Teaches to the Contemporary Philosopher.

In Homer, aidôs cannot be translated exactly, because it oscillates between conflicting emotions (courage and fear). Then which mechanism prevents this heterogeneity from diluting ? Explanations have been proposed but it has been objected that aidôs resists beeing theorized and Homer ssems to gives a rather problematic picture of aidôs, going so far as suggesting that aidôs has a power of self-refuting, what makes it an equivalent of consciousness.

Aidôs engages trust and faith in a way different from oath. It is a performative which differs from the performative you find in oath which Homer shows to be deceptive. While oath tends to exercise some control, aidôs proves itself capable of generating trust because it is disinterested. The Homeric aidôs opens the way to a culture of scruple that challenges the contemporary philosopher.

Helen as an Allegory : From Homer to Plato.

This paper focuses on Helen of Troy as an allegory and tries to show how her ambivalence, and even her splitting into two Helens in Euripides’ version, has led the main Greek authors to investigate both the characteristics of erotic desire and the power of sign as a substitute for reality.
Weeping in Heliodoros’ Aithiopika

Published: February 2017

«Pleurer » dans les Éthiopiques d’Héliodore.

Héliodore, comme les romanciers antérieurs, décrit souvent les pleurs des hommes et femmes, et les postures, gestes, expressions faciales et sons paraverbaux pour rendre l’angoisse ressentie. Les larmes expriment le chagrin mais parfois aussi la joie et la surprise. Elles manipulent quelquefois les personnes présentes et même des observateurs. Une étude des larmes et des conduites associées dans les Éthiopiques

montre en ce qui concerne la façon d’intégrer les émotions à sa fiction la variété et l’habileté de cet auteur tardif, dérivées en partie de ses précurseurs épiques et romanciers.
Flore et végétation vasculaire de la réserve naturelle volontaire de l'étang de Haute-Jarrie (Isère, Alpes du Dauphiné, France)

Créée en 1984 dans la proche région grenobloise, la réserve naturelle volontaire de l'étang de Haute-Jarrie comprend 6 grands groupements végétaux bien typés et représentatifs des différentes phases de la dynamique végétale. 160 espèces végétales ont été inventoriées et réparties dans 60 familles ; mais trois espèces végétales protégées (Gratiola officinalis L., Salix daphnoides Vill. et Pulicaria vulgaris Gaertn.), jadis citées dans l'étang, n'ont pas été retrouvées.

Un tel milieu, avec ses aménagements pédagogiques légers et intégrés au site, est susceptible d'initier le public à la composition et au fonctionnement d'une phytocénose palustre.
Innovations from the “ivory tower”: Wilhelm Barthlott and the paradigm shift in surface science
Authors: Neinhuis Christoph
Published: February 2017

This article is mainly about borders that have tremendous influence on our daily life, although many of them exist and act mostly unrecognized. In this article the first objective will be to address more generally the relation between university and society or industry, borders within universities, borders in thinking and the huge amount of misunderstandings and losses resulting from these obvious or hidden borders. In the second part and in more detail, the article will highlight the impact of the research conducted by Wilhelm Barthlott throughout his scientific career during which not only one border was removed, shifted or became more penetrable. Among the various fields of interest not mentioned here (e.g., systematics of Cactaceae, diversity and evolution of epiphytes, the unique natural history of isolated rocky outcrops called inselbergs, or the global distribution of biodiversity), plant surfaces and especially the tremendous diversity of minute structures on leaves, fruits, seeds and other parts of plants represent a common thread through 40 years of scientific career of Wilhelm Barthlott. Based on research that was regarded already old-fashioned in the 1970s and 1980s, systematic botany, results and knowledge were accumulated that, some 20 years later, initiated a fundamental turnover in how surfaces were recognized not only in biology, but even more evident in materials science.
UTILIZATION OF FACEBOOK BY SCHOOL CHILDREN IN THE APPRENTICESHIP SEEKING PROCESS
Authors: SANDER Tom , TEH Phoey Lee , SLOKA Biruta
Published: February 2017

The search for a practical apprenticeship place can be the first step in the business world for German students. The students have to apply for this placement, as Companies require applicants. Facebook is one of the most often used social networks among the younger generation in Germany, which can provide a direct communication channel between businesses and candidates. The research evaluates the reasons to use Facebook to identify a solid apprenticeship training platform for German students. Research methods applied: scientific publication analysis, survey (by paper-based questionnaire) of German students of the ninth and tenth grade. Analysis of survey data by main indicators of descriptive statistics: arithmetic mean, mode, median, and standard deviations to get an impression of evaluations on analysed aspects by survey respondents. Analysis of variance – ANOVA – is applied to study the difference of the assessments between female and male school children and the differences between the ninth and tenth classes. The existence of correlations between the intensity of use of social network sites (SNS) and the apprenticeship seeking process have been investigated. The results of the research have shown that there are differences in evaluations, on analysed aspects, between female and male school children in the analysed classes on the occasion career entry by the apprenticeship.
FORMATION OF AN INTEGRATED STOCK PRICE FORECAST MODEL IN LITHUANIA
Authors: DZIKEVIČIUS Audrius
Published: February 2017

Technical and fundamental analyses are widely used to forecast stock prices due to lack of knowledge of other modern models and methods such as Residual Income Model, ANN-APGARCH, Support Vector Machine, Probabilistic Neural Network and Genetic Fuzzy Systems. Although stock price forecast models integrating both technical and fundamental analyses are currently used widely, their integration is not justified comprehensively enough. This paper discusses theoretical one-factor and multi-factor stock price forecast models already applied by investors at a global level and determines possibility to create and apply practically a stock price forecast model which integrates fundamental and technical analysis with the reference to the Lithuanian stock market. The research is aimed to determine the relationship between stock prices of the 14 Lithuanian companies listed in the Main List by the Nasdaq OMX Baltic and various fundamental variables. Based on correlation and regression analysis results and application of c-Squared Test, ANOVA method, a general stock price forecast model is generated. This paper discusses practical implications how the developed model can be used to forecast stock prices by individual investors and suggests additional check measures.

We explored the implication of the association (or lack of it) of 6.7 GHz class II methanol (CH3OH) masers with massive dense cores (MDCs) detected (within a sample of ATLASGAL selected infrared quiet massive clumps) at 0.9 mm with Atacama Large Millimeter/submillimeter array. We found 42 out of the 112 cores (37.5%) detected with the Atacama Compact Array (ACA) to be associated with 6.7 GHz CH3OH masers. The lowest mass core with CH3OH maser association is

. The angular offsets of the ACA cores from the 6.7 GHz CH3OH maser peak positions range from 0.″17 to 4.″79, with a median value of 2.″19. We found a weak correlation between the 0.9 mm continuum (MDCs) peak fluxes and the peak fluxes of their associated methanol multibeam (MMB) 6.7 GHz CH3OH masers. About 90% of the cores associated with 6.7 GHz CH3OH masers have masses of >40 M
⊙. The CH3OH maser containing cores are candidates for embedded high-mass protostellar objects in their earliest evolutionary stages. With our ACA 0.9 continuum data compared with the MMB 6.7 GHz CH3OH maser survey, we have constrained the cores already housing massive protostars based on their association with the radiatively pumped 6.7 GHz CH3OH masers.

We present 90 mas (37 pc) resolution ALMA imaging of Arp 220 in the CO (1-0) line and continuum at

. The internal gas distribution and kinematics of both galactic nuclei are well resolved for the first time. In the west nucleus, the major gas and dust emission extends out to 0.″2 radius (74 pc); the central resolution element shows a strong peak in the dust emission but a factor of 3 dip in the CO line emission. In this nucleus, the dust is apparently optically thick (

) at

with a dust brightness temperature of ∼147 K. The column of interstellar matter at this nucleus is

cm−2, corresponding to ∼900 gr cm−2. The east nucleus is more elongated with radial extent 0.″3 or ∼111 pc. The derived kinematics of the nuclear disks provide a good fit to the line profiles, yielding the emissivity distributions, the rotation curves, and velocity dispersions. In the west nucleus, there is evidence of a central Keplerian component requiring a central mass of 8 × 108

. The intrinsic widths of the emission lines are

(west) and 120 (east) km s−1. Given the very short dissipation timescales for turbulence (≲105 years), we suggest that the line widths may be due to semicoherent motions within the nuclear disks. The symmetry of the nuclear disk structures is impressive, implying the merger timescale is significantly longer than the rotation period of the disks.
Effects of Bulk Composition on the Atmospheric Dynamics on Close-in Exoplanets
Authors: Zhang Xi , Showman Adam P.
Published: February 2017

Super Earths and mini Neptunes likely have a wide range of atmospheric compositions, ranging from low molecular mass atmospheres of H2 to higher molecular atmospheres of water, CO2, N2, or other species. Here we systematically investigate the effects of atmospheric bulk compositions on temperature and wind distributions for tidally locked sub-Jupiter-sized planets, using an idealized 3D general circulation model (GCM). The bulk composition effects are characterized in the framework of two independent variables: molecular weight and molar heat capacity. The effect of molecular weight dominates. As the molecular weight increases, the atmosphere tends to have a larger day–night temperature contrast, a smaller eastward phase shift in the thermal phase curve, and a smaller zonal wind speed. The width of the equatorial super-rotating jet also becomes narrower, and the “jet core” region, where the zonal-mean jet speed maximizes, moves to a greater pressure level. The zonal-mean zonal wind is more prone to exhibit a latitudinally alternating pattern in a higher molecular weight atmosphere. We also present analytical theories that quantitatively explain the above trends and shed light on the underlying dynamical mechanisms. Those trends might be used to indirectly determine the atmospheric compositions on tidally locked sub-Jupiter-sized planets. The effects of the molar heat capacity are generally small. But if the vertical temperature profile is close to adiabatic, molar heat capacity will play a significant role in controlling the transition from a divergent flow in the upper atmosphere to a jet-dominated flow in the lower atmosphere.

Published: February 2017

We present RCSED, the value-added Reference Catalog of Spectral Energy Distributions of galaxies, which contains homogenized spectrophotometric data for 800,299 low- and intermediate-redshift galaxies (

) selected from the Sloan Digital Sky Survey spectroscopic sample. Accessible from the Virtual Observatory (VO) and complemented with detailed information on galaxy properties obtained with state-of-the-art data analysis, RCSED enables direct studies of galaxy formation and evolution over the last 5 Gyr. We provide tabulated color transformations for galaxies of different morphologies and luminosities, and analytic expressions for the red sequence shape in different colors. RCSED comprises integrated k-corrected photometry in up to 11 ultraviolet, optical, and near-infrared bands published by the GALEX, SDSS, and UKIDSS wide-field imaging surveys; results of the stellar population fitting of SDSS spectra including best-fitting templates, velocity dispersions, parameterized star formation histories, and stellar metallicities computed for instantaneous starburst and exponentially declining star formation models; parametric and non-parametric emission line fluxes and profiles; and gas phase metallicities. We link RCSED to the Galaxy Zoo morphological classification and galaxy bulge+disk decomposition results of Simard et al. We construct the color–magnitude, Faber–Jackson, and mass–metallicity relations; compare them with the literature; and discuss systematic errors of the galaxy properties presented in our catalog. RCSED is accessible from the project web site and via VO simple spectrum access and table access services using VO-compliant applications. We describe several examples of SQL queries to the database. Finally, we briefly discuss existing and future scientific applications of RCSED and prospective catalog extensions to higher redshifts and different wavelengths.
Rassembler, regrouper, embarquer... Les trois missions logistiques de l’armée de terre française au cours de l’ Opération Dynamo
Authors: Vermesch Olivier
Published: February 2017

La percée de la Wehrmacht à Sedan entraîne, deux semaines après, l’isolement non seulement de l’armée britannique mais aussi d’une grande partie de l’armée française. Cette dernière, après avoir compris l’impossibilité de tenir un camp retranché classique, se trouve le dos à la mer. L’article reprend à la lumière d’enquêtes sur le terrain, la chronologie détaillée des huit jours qui ont permis le sauvetage de 124 000 soldats français. La question des liaisons franco-anglaises fut vitale. Contrairement à l’image bien ancrée de troupes débandées, l’état-major français réussit à organiser correctement une véritable chaîne de rembarquement malgré d’inévitables dysfonctionnements comme celui de la nuit du 2 au 3 juin, qui expliquent en partie la capture de 40 000 hommes le 4 juin.

Le Recueil sur le thé dhy ā nique , jadis faussement attribué à Rinzai Takuan Sōhō (1573-1645) mais publié dans sa version définitive en 1818, ici traduit en français, établit une série de liens entre le thé et la vie spirituelle selon le bouddhisme. Il y est question de la culture et de l’art du thé (ch. II), de la cérémonie du thé avec ses variantes, mais surtout des rapports entre le maître-invitant et son invité. Au terme de ces « raffinements » (chap. VII) et de ce « dépouillement » (chap. V), on aboutit à un moment (ch. X) où il est question d’un « thé sans invité ni maître ».
Eschatologies philosophiques du temps présent
Authors: Millischer Laurent
Published: February 2017

Trois ouvrages récents entreprennent l’analyse philosophique du dénouement actuel de l’histoire. Dans Les Cinq Époques de l’histoire, Alain Juranville entend démontrer la nécessité structurale de la fin actuelle de l’histoire comme achèvement de la vérité philosophique. Avec La Démoralisation, Christian Godin associe la crise morale contemporaine à l’exténuation du sens qu’impose le monde capitaliste organisé par la techno-science. Rémi Brague, dans Le Règne de l’homme, déplie une généalogie du projet moderne comme « anthropologie sans contexte » produisant un humanisme de la domination, dont l’échec s’avère inévitable. Ces essais ouvrent ainsi trois voies d’élaboration d’une eschatologie philosophique du temps présent.
Certains ne dispose-t-il que d’une lecture forte ?
Authors: Kupferman Lucien
Published: February 2017

Une lecture faible d’un quantifieur installe un sous-ensemble de l’ensemble notionnel. Une lecture forte installe un sous-ensemble d’un ensemble réel (= repéré indépendamment du contenu de la proposition). On veut montrer que le quantifieur certains a une lecture faible en plus de sa lecture forte. Pour ce faire, sept propriétés sont rappelées ou bien mises en évidence pour les deux types de lecture des quantifieurs en général, qui départagent, dans un sens positif ou négatif, et appliquées à certain en particulier qui est : 1) potentiellement présent dans la portée d’un opérateur négatif ; 2) présent dans des arguments de prédicats de niveau de phase ou d’individu ; 3) dans une position d’arguments de prédicats existentiels 4) dans des arguments de prédicats à sujet non thématique 5) face à des objets détachés à droite ; 6) face à des extrapositions de relatives restrictive ; 7) à des extrapositions de génitif. La conclusion veut aussi très brièvement élargir le propos et inscrire certains dans un carré lexical, adapté de Gondret [1976], sous le double paramètre de quantitatif / distinctif et discréisant / compactant, en contraste avec plusieurs , quelques , et divers / différents .
Interprétons-nous de la même manière les expressions deux pommes et deux pommes et demie ?
Authors: Nicolas David
Published: February 2017

Interprétons-nous de la même manière les expressions deux pommes et deux pommes et demie  ? Étudiant leurs équivalents anglais two apples et two and a half apples , Liebesman (2015) a récemment proposé que l’interprétation des deux expressions implique une forme de mesure, distincte du simple compte. Je commence par présenter les arguments de Liebesman concernant l’anglais. Puis j’analyse le cas du français. Je défends les thèses suivantes : l’interprétation de deux pommes implique bien le compte usuel avec les nombres entiers, tandis que l’interprétation de l’expression deux pommes et demie implique une forme d’ellipse et, dans certains cas, une réinterprétation du nom pomme .
Hubert Curien à la DGRST
Authors: Sevin Jacques
Published: February 2017

De 1973 à 1976, Hubert Curien a exercé les fonctions de Délégué général à la recherche scientifique et technique. À la tête de la DGRST qui préparait et coordonnait la politique scientifique et le budget annuel de la recherche publique, il était au cœur de la machine gouvernementale. On évoquera les temps forts du mandat d’Hubert Curien : volonté gouvernementale de relance et structuration de la recherche publique, mise en place sous son leadership d’une nouvelle organisation de la formation des jeunes chercheurs, période cruciale de l’Europe spatiale où Hubert Curien allait, par la suite, jouer un rôle clé.
Hubert Curien à la présidence du Cnes
Authors: Arnould Jacques
Published: February 2017

Président du Centre national d’études spatiales (Cnes) de juillet 1976 à juillet 1984, Hubert Curien a soutenu le programme du lanceur Ariane, avec le succès inaugural de décembre 1979, puis la création de la société Arianespace. Il est aussi à l’origine du programme d’observation spatiale Spot (Système probatoire d’observation de la Terre puis Satellite pour l’observation de la Terre). Au Cnes comme à l’Agence spatiale européenne (ESA) qu’il a présidée avec une grande diplomatie, puis au ministère de la Recherche, il a eu à cœur de mettre la science au centre de programmes spatiaux internationaux ambitieux (avec les USA et l’URSS en particulier), sans jamais oublier la dimension éducative de l’espace.
La science en fête
Authors: Ledur Marie-Claude
Published: February 2017

Hubert Curien a créé La science en fête en 1992 pour faire connaître à tous les Français le monde de la recherche et susciter des vocations chez les plus jeunes. Les directeurs d’organismes furent sollicités et, rapidement, des animations furent organisées par les laboratoires à Paris et dans toutes les régions. Les centres de culture scientifique et les musées s’associèrent à l’initiative avec enthousiasme. Le bilan sur toute la France dépassa toutes les espérances : plus de 500 000 personnes participèrent à l’évènement. Le ministre évoqua la science en fête à Bruxelles, lors d’un conseil de la recherche. Trente ans plus tard la science en fête existe toujours et touche un public de plus en plus nombreux. En 2015, dix autres pays ont également fêté la science.

Dans la continuité de l’article « Lascaux II : où l’art rencontre la science » nous avons souhaité, justement pour faire le lien entre l’artiste et le chercheur, rencontrer et interviewer Denis Vialou, préhistorien et professeur au Muséum d’histoire naturelle. Il nous livre sa réflexion sur les rapports entre l’art et la science et nous donne son opinion sur la réalisation des facsimilés de grottes ornées dont Lascaux II a été le précurseur. Ce texte est la transcription de nos échanges recueillis le 16 février 2016 au Museum.
The Impact of the Mode of Data Representation for the Result Quality of the Detection and Filtering of Spam
Authors: Hamou Reda Mohamed , Amine Abdelmalek , Tahar Moulay
Published: February 2017

Spam is now of phenomenal proportions since it represents a high percentage of total emails exchanged on the Internet. In the fight against spam, we are using this article to develop a hybrid algorithm based primarily on the probabilistic model in this case, Naïve Bayes, for weighting the terms of the matrix term -category and second place used an algorithm of unsupervised learning (K-means) to filter two classes, namely spam and ham (legitimate email). To determine the sensitive parameters that make up the classifications we are interested in studying the content of the messages by using a representation of messages using the n-gram words and characters independent of languages (because a message may be received in any language) to later decide what representation to use to get a good classification. We have chosen several metrics as evaluation to validate our results.
Modelling Design of OIS Ontology
Authors: Sawsaa Ahlam F. , Lu Joan
Published: February 2017

This chapter presents the development of OIS ontology and the main elements that formalised in OWL-DL. The OIS ontology followed Methontology as a general framework of methodology. The main result will be introduced, namely, the modelling design of OIS ontology which follows the description of the activities involved in designing the OIS ontology model. The OIS ontology model identifies the terms and definitions in the IS domain. Also, designing the ontocop system and how it can be a useful platform for supporting and assessing the OIS ontology. It starts by introducing OIS designing methodology. At the end of this chapter we will discuss how this tool will help to develop the OIS ontology to be modelled in a comprehensive and consistent manner.
Findings for Ontology in IS and Discussion
Authors: Sawsaa Ahlam F. , Lu Joan
Published: February 2017

Ontology development is meaningful and useful for both users and IR; therefore, it needs to be evaluated. In this chapter, we are going to test and evaluate the results produced in the research, which is the development of the OIS ontology life cycle. It describes the testing and validation which was applied to the whole model from the initial implementation to ensure consistency of modelled knowledge. The evaluation objective was to collect feedback on OIS ontology by using our evaluation system. The Ontocop system is a platform that has been implemented to get feedback from the IS community. The feedback is assessing and eliciting further details that support the ontology development. The evaluation and discussion will be at two levels based on Gòmez-Pérez's view.

Published: February 2017

With the standardization of ultra-high-definition formats and their increasing adoption within the multimedia industry, it has become vital to investigate how such a resolution could impact the quality of experience with respect to mission-critical communication systems. While this standardization enables improved perceptual quality of video content, how it can be used in mission-critical communications remains a challenge, with the main challenge being processing. This chapter discusses the challenges and potential solutions for the deployment of ultra-high-definition video transmission for mission-critical applications. In addition, it examines the state-of-the-art solutions for video processing and explores potential solutions. Finally, the authors predict future research directions in this area.
QoE-Driven Efficient Resource Utilisation for Video Over Critical Communication Systems
Authors: Danish Emad Abdullah , Alshamrani Mazin I.
Published: February 2017

Research in network resource utilisation introduced several techniques for more efficient power and bandwidth consumption. The majority of these techniques, however, were based on Quality of Service (QoS) and network parameters. Therefore, in this study a different approach is taken to investigate the possibility of a more efficient resource utilisation if resources are distributed based on users' Quality of Experience (QoE), in the context of 3D video transmission over WiMAX access networks. In particular, this study suggests a QoE-driven technique to identify the operational regions (bounds) for Modulation and Coding Schemes (MCS). A mobile 3D video transmission is simulated, through which the correlation between receiver's Signal-to-Noise Ratio (SNR) and perceived video quality is identified. The main conclusions drawn from the study demonstrate that a considerable saving in signal power and bandwidth can be achieved in comparison to QoS-based techniques.

Authors: El Makhtari Salima , Moussaoui Mohamed , El Oualkadi Ahmed , Samadi Hassan
Published: February 2017

This chapter provides background about Hybrid Automatic Repeat reQuest (HARQ) protocols. First, the critical situations that may be faced by wireless communication systems especially cellular mobile technologies in case of very noisy radio channels are introduced. Particularly, the chapter introduces the HARQ protocols, their main constituent components as well as some related application areas. Then, the state-of-the-art of HARQ protocols is presented. The next section explains the three basic ARQ protocols. Then, the different HARQ types are detailed. Then, a mathematical model of type II HARQ based on Rayleigh fading channel is provided. This analytical analysis is followed by a discussion of the throughput which is one of the most interesting metrics used to measure the performance of HARQ systems. The readers can find in the next section a description of the HARQ systems architecture where 3GPP LTE is used to illustrate and explain how such systems operate. Finally, the last section concludes the chapter.
Civic Responsibility Development Among College Students
Authors: Kim Young K. , Carter Jennifer L. , Armstrong Cameron L.
Published: February 2017

Using a statewide college student dataset, this chapter examines how the patterns in and predictors of civic responsibility development differ by students' racial background. Findings reveal that the level of civic responsibility does vary by student race. Results showed that Asian American students reported the lowest self-assessment of civic responsibility both at the point of college entry and in their junior or senior years, whereas African American students indicated the highest levels of civic responsibility both points of time. Findings also identify unique predictors of civic responsibility development for each racial group.
The Need for Promoting and Developing Cultural Competency in Future Teachers
Authors: Laffier Jennifer , Petrarca Diana , Hughes Janette M.
Published: February 2017

This chapter discusses the importance of promoting and developing cultural competency in future teachers. As many countries face changing demographics and student populations in schools it is essential that future teachers understand and respect different cultures, especially the role of equity and inclusion in supporting student success. The chapter provides a review of cultural competency, why teachers today need to have cultural competency, and ways in which this competency can be developed for beginning teachers. Methods of promoting and developing cultural competency for pre-service teachers are highlighted based on the experiences from a four-semester pre-service teacher program in Ontario, Canada. The ways in which cultural competency is addressed in different courses such as Digital Literacies, Human development, Mental health in Schools, and the “Foundations” series of courses (fundamentals of teaching, learning, planning and assessment) are presented. Recommendations for teacher preparation and professional development are provided.
