Autozooids in regular series in basal layer, losing orientation in successive layers. Rectangular to irregularly shaped in successive layers, separated by fine raised sutures. Frontal shield flat, covered by small rounded nodules, those near the orifice forming a weak proximolateral peristomial ridge. Frontal shield evenly perforated by small, circular pseudopores; marginal pores elongate and more conspicuous in older zooids. Uniporous septula. Primary orifice with the same characters as <i>S. ochracea</i> but larger. Large central avicularium, semielliptical to rounded-rectangular or subtriangular, in almost every zooid; placed in a central depression; crossbar complete, oval palatal foramen; mandible proximally directed. Gigantic avicularia lacking. Ovicell globular, frontally flattened, subimmersed. A wide, flat, circular area of ectooecium with rounded, elongate or irregular pseudopores, these larger at the periphery; secondary calcification of distal zooid forming a crown of prominent conical nodules encircling the exposed ectooecial area, frequently interrupted just over the orifice, showing a fine longitudinal suture; ovicell can also become covered by secondary calcification encroaching from adjacent zooids. Primary orifice of ovicellate zooids dimorphic, wider than orifice in non-ovicellate zooids and with smaller sinus; concealed by the concave proximal margin of the ovicell that extends to the proximolateral corners of the orifice; ovicell cleithral. Ancestrula unknown.</p> <p>SD, Standard deviation; N, number of measurements.</p> <p> <b>Remarks.</b> <i>Stephanotheca monoecensis</i> was described by Calvet (1927) as a variety of <i>Schizoporella ambita</i> (= <i>S. watersi</i>), from material collected off Monaco. The original label has ‘ var. <i>monaecensis</i> ’, which would be the logical name; however, when published, it appeared as <i>monoecensis</i>, which is therefore the valid spelling. Later, Gautier (1962) raised the variety to species level, placing it in the genus <i>Schizomavella</i>. This author also added new data characterizing the species, but considered that its orifice is similar to <i>S. rudis</i> (= <i>S. watersi</i>) and could instead be a variety of this species. We have revised Calvet’s (1927) original material held in MOM and MNHN and have chosen a lectotype and paralectotypes. SEM proves that the primary orifice of <i>S. monoecensis</i> and <i>S. watersi</i> are actually very different. In contrast, the primary orifice of the type material of <i>S. monoecensis</i> is similar that observed in the type material of <i>S. ochracea</i>, except for its larger size. However, the position, shape and size of the suboral avicularium are different in both species. In the holotype of <i>S. ochracea</i> it is small, oval to lanceolate and placed near the orifice, and is sometimes substituted by a gigantic avicularium; in the type material of <i>S. monoecensis</i> it is larger, subrectangular, placed in a depression in the centre of the zooid, and never gigantic. However, the shape of the avicularium in this species seems to vary considerably, from that exhibited in the types to others that are subtriangular, rounded or even oval. In a photograph of material collected in the area of Marseille (Fig. 47), sent to us by J.-G. Harmelin, two avicularia of a noticeably different size in two contiguous zooids can be seen, one of them being closer to the type of <i>monoecensis</i> and another more similar to the type of <i>ochracea</i>. Also, in the record by Zabala (1986) the avicularia are noticeably smaller than in the type material. Finally, in the material illustrated in the Synopsis of the British Fauna (Hayward & Ryland 1999), actually from Capri (P.J. Hayward, pers. comm.), the avicularium is smaller and oval. Ovicell characters are equivocal. The holotype of <i>S. ochracea</i> has only one ovicell, globular and prominent, while in the material cited by López de la Cuadra (1991) the ovicell is rather immersed. Similar variation also appears in different material of <i>S. monoecensis</i>. Finally, zooids and primary orifices are clearly larger in <i>S. monoecensis</i>.</p> <p> <i>Stephanotheca barrosoi</i>, a species also exhibiting multilaminar colonies, differs from <i>S. monoecensis</i> in its oval primary orifice, the small avicularium close to the orifice, and the sporadic presence of vicarious avicularia.</p>Published as part of <i>Reverter-Gil, Oscar, Souto, Javier & Fernández-Pulpeiro, Eugenio, 2012, A new genus of Lanceoporidae (Bryozoa, Cheilostomata), pp. 1-29 in Zootaxa 3339</i> on pages 19-22, DOI: <a href="http://zenodo.org/record/212993">10.5281/zenodo.212993</a>
Le plurilinguisme à Canton
No full textCalvet Louis-Jean, "Plurilingualisim in Canton".
The plurilingual situation in Canton is described through observing commercial transactions in two local markets and analyzing the answers of university students to a questionnaire. This study also had a pedagogic function, since the author organized these observations in collaboration with Chinese academics as an initiation to the problems of sociolinguistics. The quantitative data as to the languages used in interactions, and as to the mother and expression languages of both sellers ans students are examined in terms of language planning.Pour donner une description de la situation plurilingue à Canton, l'article s'appuie sur l'observation des transactions commerciales sur deux marchés de la ville et sur le dépouillement d'un questionnaire auprès des étudiants de l'université. Cette étude avait aussi une fonction pédagogique, l'auteur, invité à l'université, ayant mené ces observations en collaboration avec un groupe d'universitaires chinois dans le cadre d'une initiation aux problématiques de la sociolinguistique. Les données quantitatives sur les langues employées dans les interactions, et sur les langues d'origine et d'expression des marchands et des étudiants sont commentées et interprétées en fonction de considérations de politique linguistique.Calvet Louis-Jean.

Blanchard: Before & After
No full textTreballs Finals del Grau d'Economia, Facultat d'Economia i Empresa, Universitat de Barcelona, Curs: 2017-2018 , Tutor: Josep González Calvet(cast) En este texto se analizan los cambios experimentados en la enseñanza de la macroeconomía intermedia antes y después de la crisis según el manual de un autor tan significativo como Olivier Blanchard, economista jefe del FMI durante la crisis.
Para ello se revisan los tres modelos macroeconómicos más importantes del corto plazo, el modelo ISLM, el modelo OADA y el modelo macroeconómico de 3 ecuaciones simplificado, ISLMPC.
Analizaremos cómo se desarrollaban estos modelos antes de la crisis y cómo se explican después, identificando sus fortalezas y debilidades. Veremos cómo nuestro autor reconoce que esos modelos no pueden explicar la realidad de la crisis y que necesitan cambios fundamentales. Y veremos cómo introduce esos cambios para abordar la trampa de la liquidez, el límite inferior cero, la trampa de la deflación y la nueva política monetaria.
El cambio más importante que adopta Blanchard es la supresión del modelo OADA por su incapacidad de incorporar todas esas novedades sin perder la simplicidad intuitiva del modelo. En sustitución propone el modelo ISLMPC, una versión simplificada del modelo macroeconómico dinámico de 3 ecuaciones. Dicho modelo tiene un grado reducido de complejidad, es mucho más realista que el viejo OADA y, además, tiene la ventaja de poder ser simulado numéricamente con datos directos de la economía real.
Finalmente, también discutiremos la utilidad de esos modelos para explicar el comportamiento de la economía real y, en consecuencia, su utilidad en la enseñanza de las nuevas generaciones de profesionales.(eng) This text analyzes the changes experienced in the teaching of intermediate macroeconomics before and after the crisis according to the manual of a leading autor, Olivier Blanchard, chief economist of the IMF during the crisis.
To this end, the three most important macroeconomic models of the short term are reviewed, the ISLM model, the ASAD model and the simplified 3-equation macromodel, ISLMPC.
We will analyze how these models were developed before the crisis and how they are explained later, identifying their strengths and weaknesses. We will see how our author recognizes that these models cannot explain the reality of the crisis and that they need fundamental changes. And we'll see how he introduces those changes to address the liquidity trap, the zero lower bound, the deflation trap and the new monetary policy.

The most important change adopted by Blanchard is the suppression of the ASAD model due to its inability to incorporate all these novelties without losing the intuitive simplicity of the model. In substitution the author proposes the ISLMPC model, a simplified version of the dynamic 3-equation macroeconomic model. This model has a reduced degree of complexity, is much more realistic than the old ASAD and, in addition, has the advantage of being numerically simulable with direct data of the real economy.
Finally, we will also discuss the usefulness of these models to explain the behavior of the real economy and, consequently, its usefulness for teaching new generations of professionals
Pas de la Masculinitat Hegemònica a les Noves Masculinitats: evolució de les masculinitats des de la mirada de les dones
No full textTreballs Finals del Grau de Sociologia, Facultat d'Economia i Empresa, Universitat de Barcelona, Curs: 2016-2017 , Tutor: Clara Camps Calvet(cat) En aquest estudi s’investiga l’evolució de la masculinitat hegemònica a les noves masculinitats i les preferències de masculinitats dins del marc heteronormatiu a partir de la percepció de les dones que es defineixen com a heterosexuals i bisexuals del barri de Sants de Barcelona. Per aconseguir-ho es realitza una recerca bibliogràfica per tal de trobar els indicadors adequats per abordar el tema, i per conèixer les corrents teòriques que existeixen sobre el tema, tant pel que fa al canvi de masculinitats, com de creació de les mateixes. L’estudi inclou l’anàlisi d’uns resultats que són fruit d’un treball de camp a partir d’una enquesta ideada per l’investigador, amb la qual es coneix si les dones perceben que existeix o no la transformació de la masculinitat i si elles desitgen noves masculinitats. Els principals resultats mostren una evolució de les masculinitats, segons la percepció de les dones. Les dones més grans perceben que els homes de les seves edats corresponen a identitats més properes a les masculinitats hegemòniques, mentre que les joves perceben que els homes de la seva edat, corresponen a identitats lligades a les noves masculinitats. De la mateixa manera, s’observa que les preferències de les dones van per la mateixa via en cada edat, és a dir, com major edat té la dona enquestada, més hegemònica serà la masculinitat que prefereix, mentre que com més jove sigui la mateixa, més a favor estarà de les noves masculinitats, i més les preferirà.(eng) In this study, research is done regarding the evolution of the hegemonic masculinity to the new masculinities and the preferences of masculinities within the heteronormative framework through the perception of self-defined heterosexual and bisexual women from the Sants neighbourhood of Barcelona. To achieve it, a literature review is carried out with the aim of finding the adequate indicators to address the issue and to know the theoretical strands that exist on the topic, both on the masculinities change and on their creation. The study includes the analysis of the results of a field work, which is conducted through a survey created by the author, with which it is known if the women perceive or not the masculinity transformation and if they want new masculinities. The main results show an evolution of the masculinities according to the women's perception. The older women perceive that men their age correspond to identities which are closer to the hegemonic masculinities, while the younger ones perceive that men their age correspond to identities linked to the new masculinities. In the same manner, it is observed that the women’s preferences follow the same path in each age, that is to say, the older the surveyed woman is, the more hegemonic will be the masculinity which she prefers, while the younger she is, the more she will be in favour of the new masculinities, and the more she will prefer them
Risk maps of Lassa fever in West Africa
No full textBackground: Lassa fever is caused by a viral haemorrhagic arenavirus that affects two to three million people in West Africa, causing a mortality of between 5,000 and 10,000 each year. The natural reservoir of Lassa virus is the multi-mammate rat Mastomys natalensis, which lives in houses and surrounding fields. With the aim of gaining more information to control this
disease, we here carry out a spatial analysis of Lassa fever data from human cases and infected rodent hosts covering the period 1965–2007. Information on contemporary environmental conditions (temperature, rainfall, vegetation) was derived from NASA Terra MODIS satellite sensor data and other sources and for elevation from the GTOPO30 surface for the region from Senegal to the Congo. All multi-temporal data were analysed using temporal Fourier techniques to generate images of means, amplitudes and phases which were used as the predictor variables in the models. In addition, meteorological rainfall data collected between 1951 and 1989 were used to generate a synoptic rainfall surface for the same region.
Methodology/Principal Findings: Three different analyses (models) are presented, one superimposing Lassa fever outbreaks on the mean rainfall surface (Model 1) and the other two using non-linear discriminant analytical techniques. Model 2 selected variables in a step-wise inclusive fashion, and Model 3 used an information-theoretic approach in which many different random combinations of 10 variables were fitted to the Lassa fever data. Three combinations of absence:presence clusters were used in each of Models 2 and 3, the 2 absence:1 presence cluster combination giving what appeared to be the best result. Model 1 showed that the recorded outbreaks of Lassa fever in human populations occurred in zones receiving between 1,500 and 3,000 mm rainfall annually. Rainfall, and to a much lesser extent temperature
variables, were most strongly selected in both Models 2 and 3, and neither vegetation nor altitude seemed particularly important. Both Models 2 and 3 produced mean kappa values in excess of 0.91 (Model 2) or 0.86 (Model 3), making them ‘Excellent’.
Conclusion/Significance: The Lassa fever areas predicted by the models cover approximately 80% of each of Sierra Leone and Liberia, 50% of Guinea, 40% of Nigeria, 30% of each of Coˆ te d’Ivoire, Togo and Benin, and 10% of Ghana.Citation: Fichet-Calvet, E. & Rogers, D.

No full textA microscopic model of the Tian-Calvet microcalorimeter, cell design for a faster response, and measurement by a continuous procedure
No full textThe transient heat conduction equation was used as the microscopic model of the Tian-Calvet microcalorimeter. It was verified by comparing simulated and experimental calorimetric curves and used to guide sample cell design for a faster response time, for which it gave the guidelines to minimize the heat flow distance and use a heat flux that is uniform and onto the whole face of the thermopile sensor. The resulting sample cell was disc-shaped with the sample powder placed in it as a thin 0.2 mm layer on a stainless steel base with a wall thickness of 0.5 mm that covered the whole face of the thermopile on which it was placed. The rise time of the heat response curve to a step change in sample temperature, which is the response time for measuring the differential heat released, was 45 s. The response curve from a gas dose returned to the baseline within 400 s, which is the time needed to measure the integrated heat in a pulsed dosage. The accuracy of the heats measured by the calorimeter was verified by comparison with data in the literature on the adsorption of ethanol and ammonia on HZSM-5 and adsorption of methanol and ammonia on SAPO-34. The differential heat of methanol adsorption on SAPO-34 at 333 K and ammonia adsorption on HZSM-5 at 423 K were measured by both the conventional discontinuous procedure and a new continuous procedure. In the continuous procedure, gas was continuously dosed at a very slow flow rate that was kept slow enough for the gas and adsorbate to reach quasi-equilibrium. The continuous procedure has the advantages of high resolution results and a simpler experimental procedure, and a calorimetric curve could be measured within 3 h.

Testing protoplanetary disc dispersal with radio emission
No full textWe consider continuum free–free radio emission from the upper atmosphere of protoplanetary discs as a probe of the ionized luminosity impinging upon the disc. Making use of previously computed hydrodynamic models of disc photoevaporation within the framework of extreme-ultraviolet (EUV) and X-ray irradiation, we use radiative transfer post-processing techniques to predict the expected free–free emission from protoplanetary discs. In general, the free–free luminosity scales roughly linearly with ionizing luminosity in both EUV- and X-ray-driven scenarios, where the emission dominates over the dust tail of the disc and is partial optically thin at cm wavelengths. We perform a test observation of GM Aur at 14–18?GHz and detect an excess of radio emission above the dust tail to a very high level of confidence. The observed flux density and spectral index are consistent with free–free emission from the ionized disc in either the EUV- or the X-ray-driven scenario. Finally, we suggest a possible route to testing the EUV- and X-ray-driven dispersal model of protoplanetary discs, by combining observed free–free flux densities with measurements of mass-accretion rates. On the point of disc dispersal one would expect to find an M?2? scaling with free–free flux in the case of EUV-driven disc dispersal or an ?* scaling in the case of X-ray-driven disc dispersa
