Authors: Ahmed Zulfiqar , Vohra Muhammad Sufyan , Khan Muhammad Noman , Ahmed Ayaz , Khan Taseer Ahmed
Published: February 2019

Introduction: The emergence of antimicrobial resistance among bacterial community resulted in a ban on drugs as the growth promoter in poultry feed. This situation demands to explore alternatives as food supplements with health benefit to poultry. Therefore, probiotic microorganisms, which are considered as safe and possess various health benefits can be a choice. Present study was designed to explore the probiotic potential of the isolated lactobacillus species in chickens.

Methodology: Out of 220 samples, 100 Lactobacillus species were isolated from various regions of chicken intestine. They were further characterized on the basis of morphology, staining and catalase test. Species-level identification was made by amplifying Lactobacillus specific 16S rRNA gene. Out of 100 isolates, 21 were selected for sequencing on the basis of band intensity.

Results: Among 21 sequences, 16 were identified as L. paracasei (n = 6), L. salivarius (n = 3), L. johnsonii (n = 3), and L. agilis, L. fermentum, L. sakei, and L. curvatus (n = 1 each). These strains were found to be significantly acid-tolerant with 81.68 - 85.01% survival rate at pH 2)and bile-tolerant with 81.96 -84.65% survival rate at 0.3% bile. Except three; all strains showed salt tolerance to 2% and 4% NaCl. Among 21 Lactobacillus strains, 6 showed good antimicrobial activities against S. aureus, Salmonella Typhimurium and E. coli.

Conclusion: Lactobacillus species with probiotic property can be used in poultry feed formulation for their health benefit to combat gastrointestinal infections.
Hepatic/splenic abscess and/or skin and soft tissue infection as predictors of melioidosis in children
Authors: Chanvitan Supatjaree , Geater Alan , Laoprasopwattana Kamolwish
Published: February 2019

Introduction: Melioidosis can have multiple organ involvement which can then mimic other infections. The aim of this study was to determine if there are any factors significantly associated with melioidosis which can inform diagnostic evaluations before receiving the results of confirming laboratory testing.

Methodology: The charts of patients aged < 16 years admitted to Songklanagarind Hospital during 2002-2014 with a clinical presentation suspicious of melioidosis were reviewed.

Results: Of the 145 suspected cases, 27 patients had a confirmed diagnosis of melioidosis by either serology and/or culture. The melioidosis group had a higher proportion of patients with liver or splenic abscess (44.4% vs. 11.9%, p < 0.01) and were less likely to have splenomegaly by physical examination (3.7% vs. 22.9%, p = 0.02) than patients without melioidosis. Logistic regression analysis found that patients suspected of melioidosis who had (a) hepatic abscess or (b) splenic abscess or (c) skin or soft tissue infection were more likely to have melioidosis with likelihood ratios of 5.6, 4.0, and 2.2 respectively, and specificities of 0.94, 0.89, and 0.68 respectively. Suspected patients who did not have hepatic abscess, splenic abscess, or soft tissue infection were unlikely to have melioidosis with negative predictive value of 0.90.

Conclusion: patients who have clinically suspected melioidosis without skin or soft tissue infection should have hepatic-splenic ultrasonography performed, and suspected patients who have one of these 3 findings should be treated initially as melioidosis while waiting for culture or serologic test results.
Senecio carhuanishoensis H.Beltrán & J.Calvo sp. nov. (Asteraceae, Senecioneae), a new species from central Peru
Authors: Beltrán Hamilton , Calvo Joel
Published: February 2019

A new species of Senecio L. from the central Andes of Peru, S. carhuanishoensis H.Beltrán & J.Calvo sp. nov., only known from the Laraos District (Yauyos, Lima), is described and illustrated. It is a suffrutescent, rupicolous plant with the stems rather appressed to the rocks. It is characterized by its greyish-lanate indumentum covering the stem, leaves, and involucre, by having leaves oblanceolate to oblong, short-pedunculate, terminal, solitary, discoid capitula, and by displaying short glandular trichomes between the throat and the tube of the florets. It strictly grows in limestone rock crevices. Its morphology is compared with those of S. evacoides Sch.Bip. and S. ishcaivilcanus Cuatrec.
A Community of Workers in Leonidas of Tarentum
Authors: Nardone Claire-Emmanuelle
Published: February 2019

The hellenistic epigrammatist Leonidas of Tarentum inherited the representation of workers which was shaped by archaic and classical greek culture and poetry, especially by Homer. This representation included clearly distinct and separated categories of workers and a specific status of the worker in the oikos and in society. However, as this epigrammatist reshapes literary traditions by representing humble characters as a class of individuals, he creates a new representation of a community of workers. This paper will focus on two aspects of this representation, which are distinct from their Homeric model but allow the epigrammatist to allude to it: the presence in Leonidas of allusions to networks of persons who practise the same profession and the fact these networks are part of a larger community of workers, which transcends traditional, professional and/or gender boundaries.
La construction en terre crue au Néolithique
Authors: Sénépart Ingrid , Wattez Julia , Jallot Luc , Hamon Tony , Onfray Marylise
Published: February 2019

Depuis une vingtaine d’années, plusieurs découvertes d’architectures en terre crue datées du Néolithique ou de l’âge du Bronze et effectuées dans le cadre d’opérations préventives et programmées en France amènent au constat suivant : la terre massive ou bauge est employée dans la construction de murs où elle assume un rôle porteur et dans l’aménagement de sols d’habitat dès le Néolithique ancien. À partir du Néolithique moyen, son usage est récurrent, des rives de la Méditerranée au littoral de la Manche et jusque dans le Centre de la France. Les premières découvertes en Provence et en Languedoc, dès les années 1990, puis dans le reste de l’Hexagone, ont ainsi modifié le schéma d’apparition des techniques constructives en terre crue jusque-là attribuées au Bronze final. Ces faits contribuent à faire évoluer notre conception de l’habitat durant la Préhistoire récente. L’article se propose de faire un bilan des dernières découvertes en la matière et d’ouvrir quelques perspectives de recherche sur le sujet.
Les « terrains vagues » de l’âge du Fer
Authors: Nicolai Caroline von
Published: February 2019

Au cours du iie et du ier siècle avant notre ère, à la fin de l’âge du Fer, les premières villes font leur apparition dans le monde celtique. Ces sites, appelés généralement oppida, se distinguent des habitats et des fortifications de l’âge de Bronze et du Premier âge du Fer, notamment par leur énorme surface. L’occupation à l’intérieur des oppida étant souvent clairsemée, il est peu surprenant que beaucoup d’entre eux comportent des terrains vagues dont les fonctions varient sensiblement d’un site à l’autre : places publiques, zones utilisées comme champs, pâturages ou sites d’extraction de matières premières.
Du pré de la Cercle aux bains lavoirs publics de Caen

Published: February 2019

L'article se propose de croiser les données historiques et archéologiques afin d'illustrer les différents aménagements de « la Cercle », une presqu’île marécageuse touchant l'enceinte sud-ouest de la ville de Caen. Quelle qu’elle ait pu être au cours des siècles – pré exploité par les religieux du Moyen Âge au xvie siècle, bastion et foire royale du xvie au xviiie siècle, taudis, puis bains lavoirs publics au xixe siècle – l'utilisation de ce terrain renvoie tant à la question de son intégration dans le territoire urbanisé qu’à celle des moyens utilisés par les pouvoirs publics pour y parvenir, malgré des problématiques ou des nécessités différentes.
Un objet prophylactique ?
Authors: Fort Bérangère
Published: February 2019

La fouille à Mandeure, en 2012, d’un îlot urbain mêlant activités artisanales et habitations a permis la découverte, au sein d’une forge en activité jusqu’au début du iiie siècle de notre ère, d’une pièce exceptionnelle, une intaille magique en argent. Ce matériau luxueux possède, selon Pline l’Ancien, des vertus protectrices et cicatrisantes.Présentant la morphologie classique des intailles en pierre ou en verre, cette pièce est gravée sur les deux faces. La face supérieure est ornée d’un motif figuratif qui demeure obscur bien que connu sur plus d’une dizaine d’intailles : un personnage ailé chevauchant un lion en marche qui piétine un personnage masculin à terre. Le félin fait face à un personnage féminin, situé à gauche, portant le bras droit vers son visage. Un croissant de lune et une étoile à huit rayons surmontent la scène. Au revers, une inscription est grec est gravée sur trois lignes. On lit l’invocation d’origine hébraïque Iaô Abraxas.Le contexte de découverte permet d’affiner la datation de ces intailles magiques dont les gravures semblent faire écho au développement des cultes à mystères venus d’Orient dans le courant des iie et iiie siècles.
Au fil de Sirona… la déesse de Mediolanum/Mâlain
Authors: Widehen Marie-Agnès , Kasprzyk Michel
Published: February 2019

En 2014, la réalisation d’un diagnostic à Mâlain (Côte-d’Or) a offert l’opportunité de mieux connaître le site du sanctuaire occidental de Mediolanum, agglomération antique méridionale de la cité des Lingons. Dans ce grand complexe religieux, des trouvailles anciennes avaient montré l’existence d’un culte rendu à Mars Cicolluis et à Litavis/Bellona. Les recherches récentes montrent qu’au sein du sanctuaire, les fidèles s’adressaient également au dieu Apollon Mogetimarus et à la déesse Sirona pour des besoins de guérison. En effet, deux inscriptions et la mise au jour de sept ex-voto anatomiques illustrent de manière exceptionnelle un culte rendu à ce couple de divinités guérisseuses déjà attesté par le groupe de statuettes découvert à Mâlain en 1977. La sculpture exhumée lors du diagnostic figure la déesse à demi-vêtue telle une nymphe. Cette représentation est fidèle à l’image de la statuette et ce type iconographique apparaît comme isolé dans le corpus bien identifié de ce personnage divin. Les sculptures provenant notamment des sanctuaires d’Alésia (Côte-d’Or) et d’Hoscheid (Rhénanie-Palatinat) montrent Sirona habillée d’une longue tunique. En compagnie du serpent, la déesse de Mâlain n’est cependant pas sans évoquer une sculpture découverte à Cologne identifiée comme une représentation d’Hygie. Déesse à l’origine celtique dotée d’une identité bien marquée, Sirona semble avoir joui d’une faveur particulière en Gaule romaine et en Germanie pour son rôle salutaire.
Les procédés de façonnage des potiers gaulois en Cambrésis
Authors: Bardel David , Capt Pierre-Alain
Published: February 2019

Les corpus céramiques des contextes funéraires d’époque gauloise (La Tène C et D) récemment découverts dans le Cambrésis se prêtent à une étude des traces de façonnage et à une reconnaissance des procédés de montages. Ils ont également fourni l’occasion de reconstituer certains gestes techniques dans une démarche d’expérimentation conduite par le potier P.-A. Capt. Cette approche liminaire permet ainsi de considérer les savoir-faire céramiques et leur évolution, soulignant notamment la poursuite de procédés traditionnels, mais aussi l’existence de procédés mixtes originaux utilisant des dispositifs de tournage, alors même que l’usage du montage au tour n’apparaîtra que tardivement avec la romanisation.
Les transferts de techniques potières
Authors: Willems Sonja , Borgers Barbara
Published: February 2019

Les ateliers antiques de Bavay, Pont-sur-Sambre et Famars forment un groupe dont les productions sont difficiles à distinguer, car cruches et mortiers cuits en mode A sont tous tournés à partir d’argiles calcaires. Il est nécessaire pour différencier les trois officines de croiser les données typologiques et chronologiques avec une approche intégrant analyses macroscopiques, pétrographiques et chimiques. Ces dernières mettent en évidence la similarité des productions et livrent des informations complémentaires. Elles prouvent le mouvement des potiers d’une officine à l’autre, de même que le transfert de leurs techniques transmises de génération en génération. L’échantillonnage, par four et par type, montre que la production à base d’argiles calcaires évolue peu dans le temps. Les mélanges sont adaptés et ne varient que légèrement pendant trois siècles, traduisant une signature caractéristique d’un groupe de potiers.

La céramique produite par les artisans potiers de Chaillon entre la première moitié du xie siècle et la seconde moitié du xiie siècle a pu être étudiée grâce à 49 803 restes, trouvés en position secondaire dans deux fours probablement transformés en dépotoir ainsi que dans deux fosses « tessonnières » et dans des zones d’épandage très denses en céramique. Les pâtes produites se répartissent dans deux groupes techniques, caractérisés, l’un par une pâte à inclusions de calcaire coquillier, et l’autre par une pâte fine. Il s’agit d’une production homogène avec seulement cinq types de formes produits correspondant à des pots, des pots à col haut, des cruches, des poêlons et des jattes.

Published: February 2019

Un diagnostic archéologique, réalisé par l’Inrap en 2011 à Lille, a permis la découverte d’un important rejet de production d’une faïencerie. La présence d’un nombre important de pernettes, de fragments de cazettes ou plus rarement de piliers d’échappade sont des indices précieux pour appréhender les modes de cuisson de cette production. Une comparaison avec l’encyclopédie de Diderot et d’Alembert permet de documenter et de comprendre techniquement ces différents systèmes. La présence de nombreux rebuts de cuisson (biscuits, biscuits peints, céramiques glaçurées collées les unes aux autres) permet de distinguer chaque étape de la chaîne opératoire de cette manufacture. Ces données archéologiques sont confrontées à celles des archives. Certains documents, tout à fait exceptionnels, relatent en effet la provenance des matières premières, l’organisation de l’atelier ou la quantification des pièces produites. Cet article vise à caractériser la production lilloise, encore méconnue, à cause du rayonnement des deux grands centres de production que sont Delft et Rouen.

Las transformaciones de la serranilla entre Edad Media y Renacimiento
Authors: Alonso Álvaro
Published: February 2019

El propósito de este trabajo es analizar cómo evoluciona la serranilla entre 1490 y 1540. Desde el punto de vista estructural, las novedades más significativas son dos: la tendencia a suprimir la parte narrativa de la pastorela medieval, y la recuperación del modelo de la pastorela compostelana, de la que no hay ejemplos claros en la Edad Media castellana. Desde el punto de vista temático aparecen situaciones y actitudes psicológicas nuevas, como la complicidad entre el caballero y el pastor enamorados. En cambio, sigue sin aparecer en las composiciones líricas la relación caballero-pastora-pastor, típica de muchos textos franceses.

Published: February 2019

Resin transfer molding (RTM) is one technique that has been used to produce polymer composites, which consists in injecting a thermoset pre-catalysed resin into a closed mold containing a dry fiber preform. In this sense, this study aims to investigate the effect of the calcium carbonate content (CaCO3) in the polyester resin during the RTM process. Several experiments were conducted using glass fiber mat molded in a RTM system with cavity dimensions 320 x 150 x 3.6 mm, at room temperature, and different injection pressure (0.75 bar) and CaCO3content (0, 10, 20, 30 and 40%). Results of the physical parameters such as viscosity, permeability, and mobility, and flow front position of the resin into the mold along the RTM process are presented and analyzed. From the results was concluded that the higher the injection pressure and lower CaCO3content into the resin, the lower filling time.
Heat Transfer in Packed Bed Elliptic-Cylindrical Reactor: The Geometry Effect

Published: February 2019

This work aims to develop a transient three-dimensional mathematical model to predict the temperature distribution in a fixed-bed elliptical cylindrical reactor to different geometric aspect ratio (L2/L1=1.5, 2.0 and 3.0). The model considers variable thermo-physical properties, a flat temperature profile at the fluid inlet, as well as a variable porosity model. The governing equation is solved using the finite volume method, coupled with WUDS interpolation scheme and fully implicit method. Results of the temperature profile along the reactor are presented and discussed at different times. As results, it was found that the maximum rate of heat transfer within the reactor occurs near the minor half-axis region of the ellipse (cross-section area of the reactor) and it intensifies over time and that the dimensionless temperature profile is practically unchanged with the aspect ratio.
The impact of power, benefits, and risk reduction on the performance of supply chain of Sri Lankan apparel and food & beverages industries
Authors: Gallage Harsha Prabashini , Endagamage Dileepa M.
Published: February 2019

Supply chain performance (SCP) can be determined through many factors such as technical factors and relationship factors. The relationship factors mainly focus on the supply chain linkages (SCLs) created with the upstream and downstream supply chain partners. Therefore, the SCLs such as Power, Benefits, and Risk Reduction are important to any industry to enhance their SCP. This paper examines the level of impact of the Power, Benefits, and Risk Reduction on the SCP. The SCLs and the SCP are analyzed and compared using two types of industries as Apparel (AI), and Food & Beverages (F&BI) that established in Free Trade Zones in Western Province Sri Lanka. A total of 138 Managers in the fields of Supply Chain (SC) related activities were surveyed (88-AI, 50- F&BI) through a self-administrative questionnaire. Risk Reduction and Power together demonstrate a significant influence on the SCP in manufacturing sector in Sri Lanka. Further, 'Industry type' moderates the relationships of Power to SCP and Risk Reduction to SCP but not the Benefits to SCP. In F&BI, the Power, Benefits, and Risk Reduction demonstrate significant (5% level) relationships with SCP but, the Power is not showing significant (5% level) relationship with SCP in AI. In F&BI, Risk Reduction and Benefits together demonstrate significant influence on SCP. But in AI, Benefits with the Power demonstrate significant influence on SCP. AI shows higher level of SCP than the F&BI, when the same level of Power and Risk Reduction apply to their own Supply Chain.
An experimental study on feature engineering and learning approaches for aggression detection in social media
Authors: Tommasel Antonela , Rodriguez Juan Manuel , Godoy Daniela
Published: February 2019

With the widespread of modern technologies and social media networks, a new form of bullying occurring anytime and anywhere has emerged. This new phenomenon, known as cyberaggression or cyberbullying, refers to aggressive and intentional acts aiming at repeatedly causing harm to other person involving rude, insulting, offensive, teasing or demoralising comments through online social media. As these aggressions represent a threatening experience to Internet users, especially kids and teens who are still shaping their identities, social relations and well-being, it is crucial to understand how cyberbullying occurs to prevent it from escalating. Considering the massive information on the Web, the developing of intelligent techniques for automatically detecting harmful content is gaining importance, allowing the monitoring of large-scale social media and the early detection of unwanted and aggressive situations. Even though several approaches have been developed over the last few years based both on traditional and deep learning techniques, several concerns arise over the duplication of research and the difficulty of comparing results. Moreover, there is no agreement regarding neither which type of technique is better suited for the task, nor the type of features in which learning should be based. The goal of this work is to shed some light on the effects of learning paradigms and feature engineering approaches for detecting aggressions in social media texts. In this context, this work provides an evaluation of diverse traditional and deep learning techniques based on diverse sets of features, across multiple social media sites.

Те же результаты получены для процесса с запаздыванием, в котором распределение $(\xi(1),\eta(1))$ отличается от распределения остальных шагов. На основе этих результатов получены локальные предельные теоремы для процессов с регенерацией и для аддитивных функционалов от конечных цепей Маркова, включающие нормальные, умеренные и большие уклонения.

Published: February 2019

La borréliose de Lyme est une pathologie infectieuse liée à des bactéries du genre Borreliella, récemment séparé taxonomiquement des Borrelia. Son diagnostic associe des critères épidémiologiques, anamnestiques, cliniques et biologiques compatibles avec une borréliose de Lyme. La manifestation clinique la plus fréquente est l’érythème migrant. Les pathogènes peuvent ensuite disséminer vers les différents tissus et organes, incluant principalement le système nerveux, les articulations, et la peau. Les tests biologiques, principalement basés sur la sérologie, sont essentiels au diagnostic de la maladie, à l’exception de l’érythème migrant dont le diagnostic reste exclusivement clinique. La recherche directe de Borrelia ou de Borreliella par culture ou par PCR reste l’apanage de laboratoires spécialisés, mais représente une aide précieuse pour le diagnostic des formes atypiques de la maladie ou lorsque les données cliniques n’ont pas permis d’établir de façon certaine le diagnostic étiologique.
Goodman e o projeto de uma definição construtiva de “indução válida”
Authors: Carvalho Eros Moreira de
Published: February 2019

In Fact, Fiction and Forecast, Nelson Goodman claims that the problem of justifying induction is not something over and above the problem of describing valid induction. Such claim seems to open up the possibility that the new riddle of induction could be addressed empirically. Discoveries about psychological preferences for projecting certain classes of objects could function as a criterion for determining which predicates are after all projectible. In this paper, I argue that Goodman’s claim must be construed within his project for constructional definitions, which is methodologically oriented by reflective equilibrium. The description of inductive practice is committed to the articulation of the extension of the class selected by the predicate ‘valid induction’. The mutual adjustment between theoretical considerations and inductive practice involved in the proposal of a definition of ‘valid induction’ must preserve that practice as much as possible, there is no way to get rid of entrenchment. Empirical discoveries about the psychological mechanism that underlies projections may help that adjustment but they cannot substitute the role played by the entrenchment of predicates.

Published: February 2019

As Instituições Públicas de Ensino Superior podem ser entendidas como grandes consumidoras de bens e serviços, no caso do Brasil. Para diminuir os impactos negativos desse consumo, essas entidades possuem função primordial na difusão e implantação de ideias sustentáveis. Assim, esse estudo investigou  as práticas sustentáveis adotadas pelos técnicos administrativos da Universidade Federal Rural de Pernambuco – Unidade Acadêmica de Garanhuns (UFRPE/UAG), observando os eixos da Agenda Ambiental da Administração Pública (A3P), bem como o grau de conhecimento desses servidores sobre temáticas de sustentabilidade na Administração Pública. Utilizou-se como metodologia de abordagem o estudo de caso, sendo a pesquisa classificada como descritiva, de natureza qualitativa. Para o levantamento de dados, aplicou-se um questionário junto aos técnicos administrativos da Unidade e uma entrevista semiestruturada com o Diretor Administrativo. Os resultados demonstraram que na UFRPE/UAG existem várias iniciativas de ações sustentáveis, porém, não se percebeu nenhuma política institucional que vise o desenvolvimento sustentável da organização. Observou-se ainda que, os técnicos possuem conhecimento limitado sobre instrumentos de implantação de práticas sustentáveis, podendo acarretar dificuldades futuras para o estabelecimento dessas ações na Unidade estudada. A partir desses resultados, conclui-se que as medidas de sustentabilidade preconizadas pela A3P ainda não se encontram consolidadas na instituição.
Early Identification of Sensory Processing Difficulties in High-Risk Infants
Authors: Flanagan Joanne E. , Schoen Sarah , Miller Lucy Jane
Published: February 2019

OBJECTIVE. Our objective was to determine the extent to which young children at high risk for sensory processing difficulties differed from those who were at low risk.

METHOD. We compared high- versus low-risk young children using standardized measures. High-risk participants had older siblings identified as having sensory processing difficulties after a comprehensive occupational therapy evaluation (n = 13); low-risk participants (n = 16) had typically developing siblings and no family history of sensory or other neurological disorders.

RESULTS. High-risk infants scored significantly lower on the Language and Cognitive scales of the Bayley Scales of Infant and Toddler Development–Third Edition. The high-risk group presented with more atypical positions on the Toddler and Infant Motor Evaluation and fewer sensation-seeking behaviors on the Toddler Sensory Profile–2.

CONCLUSION. Results suggest that sensory, motor, cognitive, and language dimensions may be associated with sensory processing difficulties. Implications exist for the design of future studies and for early intervention.
Aerosol effects on deep convection: the propagation of aerosol perturbations through convective cloud microphysics
Authors: Heikenfeld Max , White Bethan , Labbouz Laurent , Stier Philip
Published: February 2019

Abstract. The impact of aerosols on ice- and mixed-phase processes in deep convective
clouds remains highly uncertain, and the wide range of interacting
microphysical processes is still poorly understood. To understand these
processes, we analyse diagnostic output of all individual microphysical
process rates for two bulk microphysics schemes in the Weather and Research
Forecasting model (WRF). We investigate the response of individual processes
to changes in aerosol conditions and the propagation of perturbations through
the microphysics all the way to the macrophysical development of the
convective clouds. We perform simulations for two different cases of
idealised supercells using two double-moment bulk microphysics
schemes and a bin microphysics scheme. The simulations cover a comprehensive
range of values for cloud droplet number concentration (CDNC) and cloud
condensation nuclei (CCN) concentration as a proxy for aerosol effects on
convective clouds. We have developed a new cloud tracking algorithm to
analyse the morphology and time evolution of individually tracked convective
cells in the simulations and their response to the aerosol perturbations. This analysis confirms an expected decrease in warm rain formation processes
due to autoconversion and accretion for more polluted conditions. There is no
evidence of a significant increase in the total amount of latent heat, as
changes to the individual components of the integrated latent heating in the
cloud compensate each other. The latent heating from freezing and riming
processes is shifted to a higher altitude in the cloud, but there is no
significant change to the integrated latent heat from freezing. Different
choices in the treatment of deposition and sublimation processes between the
microphysics schemes lead to strong differences including feedbacks onto
condensation and evaporation. These changes in the microphysical processes
explain some of the response in cloud mass and the altitude of the cloud
centre of gravity. However, there remain some contrasts in the development of
the bulk cloud parameters between the microphysics schemes and the two
simulated cases.
Physical-biogeochemical regional ocean model uncertainties stemming from stochastic parameterizations and potential impact on data assimilation

Published: February 2019

Abstract. We generate ocean biogeochemical model ensembles including several kinds of stochastic parameterizations. The NEMO stochastic modules are complemented by integrating a subroutine to calculate variable anisotropic spatial scales, which are of particular importance in high-resolution coastal configurations. The domain covers the Bay of Biscay at 1/36° resolution, as a case study for open-ocean and coastal shelf dynamics. At first, we identify uncertainties from assumptions subject to erroneous atmospheric forcing, ocean model improper parameterizations and ecosystem state uncertainties. The error regimes are found to be mainly driven by the wind forcing, with the rest of the perturbed tendencies locally augmenting the ensemble spread. Biogeochemical uncertainties arise from inborn ecosystem model errors and from errors in the physical state. Model errors in physics are found to have larger impact on chlorophyll spread than those of the ecosystem. In a second step, the ensembles undergo verification with respect to observations, focusing on upper-ocean properties. We investigate the statistical consistency of prior model errors and observation estimates, in view of joint uncertainty vicinities, associated with both sources of information. OSTIA-SST L4 distribution appears to be compatible with ensembles perturbing physics, since vicinities overlap, enabling data assimilation. The most consistent configuration for SLA along-track L3 data is in the Abyssal plain, where the spread is increased due to mesoscale eddy decorrelation. The largest statistical SLA biases are observed in coastal regions, sometimes to the point that vicinities become disjoint. Missing error processes in relation to SLA hint at the presence of high-frequency error sources currently unaccounted for, potentially leading to ill-posed assimilation problems. Ecosystem model-data samples with respect to Ocean Colour L4 appear to be compatible with each other only at times, with data assimilation being marginally well-posed. In a third step, we illustrate the potential influence of those uncertainties on data assimilation impact exercise, by means of multivariate representers and EnKF-type incremental analysis for a few members. Corrections on physical properties are associated with large-scale biases between model and data, with diverse characteristics in the open-ocean and the shelves. The increments are often characteristic of the underlying mesoscale features, chlorophyll included due to the vertical velocity field. Small scale local corrections are visible over the shelves. Chlorophyll information seems to have a very measurable potential impact on physical variables.

Abstract. This study presents the first detailed calcareous nannofossil assemblage data from the Late Cretaceous succession of the subsurface Aruma Basin, north Oman. The taxonomic description and documentation of assemblage composition are based on extensive quantitative analysis of ditch cuttings and side-wall samples from eight hydrocarbon exploration wells across north Oman. The samples studied from those wells cover the Coniacian to earliest Maastrichtian deep marine shales and marls of the subsurface Fiqa Formation. These fine-grained siliciclastic deposits often yield moderately to well-preserved nannofossil assemblages, especially in the Campanian intervals. Consequently, diverse assemblages have been recorded from the Fiqa Formation, with a total diversity of ∼200 species, including two new species, Staurolithites ormae sp. nov. and Chiastozygus fahudensis sp. nov., which are illustrated and described. Extensive imaging of this diversity is provided here, as are stratigraphic distributions of the main components from a key reference well in north Oman, W-4. Poorly described groups such as Staurolithites are closely investigated and their utility for stratigraphic applications is highlighted. Relative abundances of nannofossil taxa with strong palaeoenvironmental preferences have revealed new insights into the palaeo-productivity of the basin. High-fertility species like Discorhabdus ignotus, Biscutum constans and Zeugrhabdotus erectus show substantial variations in abundance throughout the Fiqa Formation, reflecting long-term shifts in the productivity conditions of the basin. This is supported by abundance patterns of Watznaueria barnesiae and Micula staurophora that show a broadly inverse correlation with the high-fertility species. The Fiqa Formation represents a key regional seal unit for the Cretaceous hydrocarbon reservoirs of Oman, as well as being a productive unit elsewhere in the Arabian Peninsula. Beyond the Aruma Basin of Oman, this study will provide a key reference point for future biostratigraphic or palaeoenvironmental analyses of the Late Cretaceous calcareous nannofossil assemblages across the Middle East and other southern Tethyan areas.
Buying into the Ideal Performance of Womanhood: Gendered Marketing in the Recontextualization of “She’s Always a Woman” for John Lewis’ Advertising Campaign
Authors: Doherty Emma
Published: February 2019

This paper investigates the role of Fyfe Dangerfield’s cover of “She’s Always a Woman” by Billy Joel, within the presentation of heteronormative gender roles in John Lewis’ 2010 advertising campaign. After outlining the narrative of the advertisement and the ways in which the female protagonist is gendered from girlhood to womanhood, this paper draws upon the work of feminist scholar Judith Butler to problematize John Lewis’s portrayal of gender to show how it perpetuates heteronormative stereotypes. Then, drawing on theories of popular music surrounding identity and the importance of lyrics, John Lewis’ use of Fyfe Dangerfield’s cover is analyzed, outlining the way in which the music strengthens a simplistic narrative of ideal girlhood and womanhood, as well as how it encourages potential customers to identify with the brand. The paper then questions whether John Lewis is able to challenge heteronormativity due to their established brand identity or whether the responsibility falls upon the society, and concludes that it is essential to challenge the function of gender and music within advertisements.
Performing Ritual: Physical and Musical Gesture in Benjamin Britten’s Curlew River
Authors: Tucker Helen
Published: February 2019

Benjamin Britten’s Curlew River (1964) defies traditional genre labels, exhibiting characteristics of opera, Japanese Noh drama, and religious ritual. Set in medieval England and given a Christian theme, Curlew River is based on the Noh play Sumidagawa and uses a unique language of physical gesture inspired by Noh traditions. The integration of these physical gestures with the music is one of the ways in which Curlew River projects an atmosphere of ritual. In this paper I examine two passages from Curlew River, each of which demonstrates a close connection between the development of individual musical gestures and the progression of physical actions performed at the same time. In the arietta “Near the Black Mountains,” sung by the character of the Madwoman, the subtle development of a single musical figure is linked to the gradual transformation of the actor’s posture. A similar relationship is present in the Ferryman’s introductory scene, in which physical movements act as punctuation for a sequence of musical statements. In both instances, musical and physical gesture are integrated into a unified form of expression, the intensity and focus of which lend Curlew River its ritual quality.
Less is More, and More is Less, More or Less: The Historical Progression, Aesthetic Characteristics, and Physical Limitations of Minimalism
Authors: Boer Sam
Published: February 2019

Since its emergence as an aesthetic category in the mid-twentieth century, minimalism has been contentious amongst scholars of all forms of art. It has been alternately celebrated, questioned, and condemned by not only its critics, but also the artists whose works have been given the historical title “minimalist.” This article explores the emergence of minimalist music, examining its relation to the earlier “avant-garde” works of John Cage and other eclectic influences, such as jazz and Eastern music. In doing so, this article attempts to establish a broad understanding of the elements integral to minimalist music, with a special focus on the composers La Monte Young, Terry Riley, and Steve Reich. The works of Riley and Reich are compared to the works of visual artists Barnett Newman and Sol LeWitt in order to highlight the pivotal elements of the minimalist aesthetic, including repetition, simplicity, and, to borrow Cage’s term, “Unfixity.” This article concludes that the minimalist compositions of the aforementioned composers ultimately demonstrate the integral characteristics of minimalism better than their visual counterparts, due to the temporal nature of music. However, the article seeks to demonstrate the importance of contemplating visual and musical interpretations of minimalism together, as they are complimentary windows into this modern movement.
Lustmord or Liebestod? Death in Ernst Krenek and Oskar Kokoschka's Orpheus und Eurydike
Authors: Harrington Leo
Published: February 2019

In 1923, Ernst Krenek composed an operatic setting of Orpheus und Eurydike, a drama by painter and occasional playwright Oskar Kokoschka. Because musicologists and opera houses alike have overlooked this work, credit afforded to Krenek for his role in Weimar modernity is often confined to the Zeitoper vein of 1920s European culture: the cosmopolitan, jazz-inspired, contemporary aesthetic of Krenek’s 1927 Jonny Spielt Auf. This article, the first English-language study devoted to Orpheus und Eurydike, explores Krenek’s contribution to another crucial facet of Weimar culture: the Austro-German identity crisis provoked by defeat in World War I and social upheaval.
After tracing the opera’s rich genealogy and situating it in the lives of its creators (Alma and Gustav Mahler, among others, influenced Kokoschka's original play), this paper focuses on the drama’s multiple death scenes. Drawing on scholar Maria Tatar’s study of the Weimar obsession with sexually-tinged female death, I argue through score and libretto analysis that Krenek and Kokoschka synthesize aspects of the contemporary Lustmord (sexual murder) trope with elements of the Wagnerian Liebestod (love death) archetype. Rather than reconcile them with their artistic predecessors, however, this synthesis fleshes out the Lustmord latent in any Liebestod. With its first performance in 1926, this opera joined the ranks of “progressive” works by male artists who used aesthetic violence against women to navigate the Weimar identity crisis—in many ways, a crisis of masculinity. Paying Orpheus und Eurydike the attention it deserves underscores Krenek’s seminal but underappreciated role in both the glittering and dark sides of Weimar culture, and reveals just how interrelated those two sides are. Though it retells a well-worn classical myth, this Orpheus is as much an “opera of its time” as Jonny.
Performing Feminine Aging: The Marschallin’s Body in Der Rosenkavalier
Authors: Krawetz Alexandra
Published: February 2019

This paper applies theories from gerontology to analyze the music and text from Richard Strauss and Hugo von Hofmannsthal’s Der Rosenkavalier (1911) in order to examine the Marschallin’s attitude towards her aging female body. After illustrating the signifiers that code the Marschallin’s body as feminine, this paper incorporates Chris Gilleard’s idea from gerontology, that embracing feminine sexuality prevents the desexualizing process of aging, to examine the Marschallin’s sexual escapism. Then, with the incorporation of biographical accounts discussing reflection on past experiences and Marja Saarenheimo’s gerontological theory that memories are embodied processes, the paper analyzes how aspects of nostalgia relate to the Marschallin’s process of remembering her younger body through musical and textual repetition. The paper concludes with a brief examination of the extra-musical connotations of the waltz and an investigation of the Marschallin and waltz tempi through the lens of gerontology, which revisits the topics of sexual escapism and nostalgia. At the end of the opera, this analysis of the Marschallin shows that she accepts her aging body and exerts control over her own life.
Zarlino, Anamorphosis, and Cinquecento Italy
Authors: Li Edwin
Published: February 2019

This paper examines the relationship between Gioseffo Zarlino’s personal considerations and the socio-cultural circumstances in Cinquecento Italy on the basis of anamorphosis—the idea that an object can be understood from multiple angles. Arguably one of the most important theorists of the sixteenth century, Zarlino, although cognizant of chords as vertical constructs, deliberately disguised tonality as modality. This prompts a myriad of questions as to why he did not further develop his theory into a major-minor schema, given that he had already emphasized the Ionian and Aeolian modes in Le Istitutioni Harmoniche. This paper explores the reasons behind his conservatism, arguing that Zarlino’s religious posts and the tumultuous religious-cultural-political climate of late-sixteenth-century Venice influenced his anamorphic inclinations. The paper also attributes his constraint to the prevalent Renaissance concept of the imitation of nature. By looking into the essential qualities of nature, notably eternality, this paper claims that the imitation of nature can explain both the perpetuation of modality and Zarlino’s adoption of tonality. The paper concludes that Zarlino’s belief in God can be seen as an overarching force in his theoretical formulation, positing a hierarchical relationship among the factors discussed.
The Turkish Bağlama: A Sacred Symbol of Alevi Identity
Authors: Adams Rashid Epstein
Published: February 2019

For the Alevi, the bağlama has become a powerful symbol of group identity. This paper discusses the important role that this Turkish folk instrument has in Alevi musical traditions and practices by first contextualizing the historical position of the Alevi in Turkish society, and then by examining the role of the bağlama in traditional ceremonial performance contexts. Finally, this paper examines the role Arif Sağ, a popular bağlama musician, played in cultural revival and how the sphere of his influence contributed directly to the bağlama becoming a sacred symbol of Alevi identity.
