Last glacial ice sheet dynamics offshore NE Greenland – a case study from Store Koldewey Trough
Authors: Olsen Ingrid Leirvik , Rydningen Tom Arne , Forwick Matthias , Laberg Jan Sverre , Husum Katrine 
Published: December 2020

Abstract. The presence of a grounded Greenland Ice Sheet on the northeastern part of
the Greenland continental shelf during the Last Glacial Maximum is supported
by new swath bathymetry and high-resolution seismic data, supplemented with
multi-proxy analyses of sediment gravity cores from Store Koldewey Trough.
Subglacial till fills the trough, with an overlying drape of maximum 2.5 m
thick glacier-proximal and glacier-distal sediment. The presence of
mega-scale glacial lineations and a grounding zone wedge in the outer part
of the trough, comprising subglacial till, provides evidence of the
expansion of fast-flowing, grounded ice, probably originating from the area
presently covered with the Storstrømmen ice stream and thereby previously
flowing across Store Koldewey Island and Germania Land. Grounding zone
wedges and recessional moraines provide evidence that multiple halts and/or
readvances interrupted the deglaciation. The formation of the grounding zone
wedges is estimated to be at least 130 years, while distances between the
recessional moraines indicate that the grounding line locally retreated
between 80 and 400 m yr−1 during the deglaciation, assuming that the
moraines formed annually. The complex geomorphology in Store Koldewey Trough
is attributed to the trough shallowing and narrowing towards the coast. At a
late stage of the deglaciation, the ice stream flowed around the topography
on Store Koldewey Island and Germania Land, terminating the sediment input
from this sector of the Greenland Ice Sheet to Store Koldewey Trough.
El sexismo de la revista satírica El Papus (1973-1987). La lacra que cuestiona su papel liberador en la Transición española
Authors: Gómez Mompart Josep Lluís , Iranzo Cabrera María 
Published: December 2020

Se investiga el papel de la revista satírica El Papus, contrapoder informativo durante la Transición española, en la detracción de la lacra social del machismo. Para ello se ha llevado a cabo el análisis cuantitativo y cualitativo de los comentarios y roles asignados a la mujer en una muestra de 4.661 piezas publicadas en todo su periplo (1973-1987) y registradas en una base de datos relacional. Por un lado, esta visión androcéntrica fue fruto de una redacción mayoritariamente formada y dirigida por hombres que tratan de satisfacer las necesidades de un público constituido por hombres (80%) reprimidos sexualmente; y, por otro lado, buscó también la provocación de los represores poderes fácticos, que, aunque persiguieron gubernamental y judicialmente el ataque a la moral de muchas de las piezas sexistas, no cuestionaron en general el uso explotador de la mujer como recurso
Expresiones de machismo y violencia en los personajes masculinos del cine de Pedro Almodóvar: una revisión cronológica
Authors: Garrido Lora Manuel , Ramírez Alvarado María del Mar 
Published: December 2020

Esta investigación se centra en los personajes masculinos del director de cine Pedro Almodóvar. En primer lugar, analiza la presencia recurrente del nacionalismo en sus tramas a través de la figura del “macho ibérico” que se nutre del cine español del tardofranquismo y de la Transición, y definido mediante los valores del hombre español tradicional, así como por la conexión con lo sexual, el humor y la creación de identidades disidentes. En segundo término, se estudian las representaciones de la violencia en el cine de Almodóvar como un rasgo de ejercicio del poder característico del machismo español tradicional, expresada unas veces mediante la postura, la gestualidad o el control del espacio-tiempo; otras, de forma explícita, mediante la verbalización y la pura agresión física

Les dynamiques démographiques dans l’espace francophone face aux enjeux de l’immigration internationale de langue française au Québec et au Canada
Authors: Marcoux Richard , Richard Laurent 
Published: December 2020

L’importance de l’immigration internationale est assurément un enjeu sociopolitique central au Québec. Elle pose des défis tout aussi considérables pour les communautés francophones minoritaires réparties à travers le Canada. Dans les deux cas, des efforts sont menés afin de favoriser les candidats à l’immigration qui maîtrisent la langue française. Une question importante demeure : d’où proviendront ces francophones ? Après avoir dressé un portrait d’ensemble du vaste espace francophone mondial, à partir de tendances passées et futures, nous examinons les principaux éléments qui permettent de comprendre la phénoménale croissance du nombre de francophones liée particulièrement aux dynamiques sociodémographiques observées sur le continent africain.
Migrations franco-yukonnaises : la mise en récit par l’art d’une identité nordique
Authors: Comeau Marie-Hélène 
Published: December 2020

Cet article porte sur l’identité franco-yukonnaise marquée par la migration qui se révèle à travers la création artistique et le récit. Menée dans une perspective de recherche-action, cette démarche a pour but de faire émerger par un projet d’art le sens que donnent des membres de la communauté franco-yukonnaise à leur identité construite entre le lieu d’origine et celui de résidence qu’est le Yukon. À partir de concepts propres à l’expérience identitaire dans la création, la recherche s’attarde au parcours migratoire raconté par des Franco-Yukonnaises selon la modalité de deux mises en récit de leur histoire : 1) par la création d’un projet d’art axé sur le thème de leur histoire migratoire ; et 2) par la parole avec le récit de vie. Ce témoignage émergeant d’une intervention en art s’inscrit dans une approche plus large de la recherche-action visant la compréhension d’un phénomène social.
La Suite manitobaine de Roger Auger : sociolectes, médiations linguistiques et institutionnelles
Authors: Valenti Jean 
Published: December 2020

Journalistes, directeurs de théâtre et critiques littéraires insistent sur l’importance de la langue, du réalisme et de la représentation sociale dans le théâtre franco-manitobain des années 1970. Chacun à sa manière, ils poursuivent une réflexion sur la mise en récit des codes linguistiques en usage dans la communauté franco-manitobaine. Ils signalent aussi qu’un dénominateur commun se profile au-delà des effets stylistiques qu’occasionne l’usage d’une variété du français canadien : le franglais. Cet article met en relief quelques aspects caractéristiques de cette problématique sociolinguistique en prenant comme corpus de référence la Suite manitobaine de Roger Auger : prises de position sur le français et l’anglais, rapports entre ces langues et la littérature dramatique, émergence et autonomisation d’une dramaturgie franco-manitobaine. L’auteur les explique dans la perspective des relations complémentaires qu’entretiennent deux types de médiations sémiotiques (linguistique et institutionnel) et du sociolecte de la langue française auquel celles-ci donnent lieu.
Travers et traversées de la langue française remixée au Canada : du joual de Michel Tremblay, au chiac de France Daigle, au franglais de Marc Prescott et de Stéphane Oystryk
Authors: Gaboury-Diallo Lise 
Published: December 2020

Le contact continu entre l’anglais et le français au Canada a favorisé le développement de langues vernaculaires distinctes : le joual au Québec, le chiac en Acadie et lefranglaisau Manitoba français. Le succès littéraire de Michel Tremblay et de France Daigle, qui ont choisi le joual et le chiac respectivement, illustre comment l’hétérolinguisme peut être exploité comme vecteur de création. Au Manitoba, Marc Prescott et Stéphane Oystryk ont choisi d’écrire enfranglais : le premier dans la représentation théâtrale deSex, lies et les Franco-Manitobains(1993), le second dans son long métrageFM Youth(2014). Cette langue familière sert de tremplin pour sonder la prise de « conscience altéritaire de minoritaire » (Émir Delic) et agit comme prisme où se réfracte une dynamique conflictuelle complexe. Centrée sur des enjeux idéologiques, la rhétorique « remixée » de cette jeunesse, doublement marginalisée, révèle un repositionnement épistémologique important, celui d’une altérité assumée.
Analysis of Rice Productivity among Beneficiaries of Anchor Borrowers Programme in Adamawa State, Nigeria: Data Envelopment Analysis Approach
Authors: Bitrus A. , Sulumbe I. M. , Ibrahim A. 
Published: December 2020

Rice production in Nigeria has always been dominated by small scale farmers using traditional crude methods which are inefficient, resulting in low yield. Various measures have been taken by the government to improve rice production with the view of achieving self-sufficiency in rice production for consumption as well as export. Despite these measures, rice has not been sufficiently produced to meet the demand of the growing population in Adamawa State. So many problems might have contributed to this, which could be due to lack of adaptable rice varieties and low level of productivity of resources used by the rice farmers among others. Recently, the federal government introduced the anchor borrowers programme (ABP) with the goal of helping rice farmers to achieve desired output using improved production resources. This paper examined rice productivity and factors affecting rice farmers’ productivity among beneficiaries of anchor borrowers programme in Adamawa State, Nigeria. A multistage random sampling procedure was used in selecting the respondents. A structured questionnaire is administered to 139 farmers spread across 3 Local Government Areas to obtain information on farmer’s socio-economic variables, inputs used and output obtained in rice production. The objectives were analyzed using descriptive statistics, data envelopment analysis and OLS regression. The DEA result for level of productivity revealed that the average technical efficiency of 0.71, a minimum of 0.02 and a maximum of 1.0, indicating that the inefficient farmers could decrease their levels of input usage by 29% to produce the same levels of outputs to be at the same level with the frontier farmers. The results showed that the double log functional form gave the best line of fit. R2 value was about 86% and statistically significant at 1% level. Seed (0.882), family labour (0.712), hired labour (0.109), herbicide (0.548), fertilizer (0.200) and land (0.211) were positively and significantly related to productivity at different probability levels. Based on the findings, the study concluded that the mean technical efficiency (productivity) score was 0.71 indicating a high level of productivity. The study also found that all the production factors used by rice farmers among anchor borrower’s beneficiaries had a positive influence on the productivity levels of the rice farmers. Hence, productivity among rice farmers depends largely on their production factors.

Authors: Sergio Magos Ramírez , Sarai Murillo Cuevas Damarix , Avatar Flores Gutiérrez , Varun Thautam , Juan Serrano Arellano 
Published: December 2020

Aims: Analyze the thermal quality provided by the building elements of Huichol vernacular housing concerning the climatic conditions of San Andrés Cohamiata, Jalisco.
Study Design: The analysis was performed through a simulation of computer housing, for which the characteristics of the materials and EPW (Energy Plus Weather) data of 2018 from the study area were applied to the model, analyzed in programs such as 2D Sun-Path, 3D Sun-Path and Opaque.
Place and Duration of Study: Universidad Autónoma de Querétaro, Graduate of Architecture, Faculty of Engineering, between January and March 2019.
Methodology: First, a bibliographic and field study was carried out to verify the materials and construction processes of Huichol housing. The computer housing model was designed to apply the characteristics of the materials, as well as the location and orientation handled by the Huichol ethnic group. Subsequently, EPW (Energy Plus Weather) data from the study area were introduced to opaque software to perform thermal analysis of the house and various factors are studied such as thermal mass and insulation, heat gain/loss, direct radiation, diffuse, dry bulb temperature, among others. Also, in software such as 2D Sun-Path and 3D Sun-Path, the study of sunbathing and shadows of the house was carried out.
Results: The orientation of the house allows them to make better use of solar radiation at different times of the year. Its construction elements (wall thickness, material, and ceiling structure) decrease the overheating of the space in summer. Adobe walls have a thermal delay of 4 hours, and internal conditions are optimal to maintain thermal comfort in summer and winter. Internal temperatures during the year range from 20 to 25°C.
Conclusions: Huichol culture has important knowledge in the construction with natural materials, as these allow positive thermal behaviour in the face of the climatic conditions of the area throughout the year. These housing characteristics may apply to other ethnic groups in the region with limited economic resources, to improve their living conditions.

AbstractThe heart is the first organ to develop in the human embryo through a series of complex chronological processes, many of which critically rely on the interplay between cells and the dynamic microenvironment. Tight spatiotemporal regulation of these interactions is key in heart development and diseases. Due to suboptimal experimental models, however, little is known about the role of microenvironmental cues in the heart development. This study investigates the use of 3D bioprinting and perfusion bioreactor technologies to create bioartificial constructs that can serve as high‐fidelity models of the developing human heart. Bioprinted hydrogel‐based, anatomically accurate models of the human embryonic heart tube (e‐HT, day 22) and fetal left ventricle (f‐LV, week 33) are perfused and analyzed both computationally and experimentally using ultrasound and magnetic resonance imaging. Results demonstrate comparable flow hemodynamic patterns within the 3D space. We demonstrate endothelial cell growth and function within the bioprinted e‐HT and f‐LV constructs, which varied significantly in varying cardiac geometries and flow. This study introduces the first generation of anatomically accurate, 3D functional models of developing human heart. This platform enables precise tuning of microenvironmental factors, such as flow and geometry, thus allowing the study of normal developmental processes and underlying diseases.

AbstractIn this work, the covalent attachment of an amine functionalized metal‐organic framework (UiO‐66‐NH2 = Zr6O4(OH)4(bdc‐NH2)6; bdc‐NH2 = 2‐amino‐1,4‐benzenedicarboxylate) (UiO‐Universitetet i Oslo) to the basal‐plane of carboxylate functionalized graphene (graphene acid = GA) via amide bonds is reported. The resultant GA@UiO‐66‐NH2 hybrid displayed a large specific surface area, hierarchical pores and an interconnected conductive network. The electrochemical characterizations demonstrated that the hybrid GA@UiO‐66‐NH2 acts as an effective charge storing material with a capacitance of up to 651 F g−1, significantly higher than traditional graphene‐based materials. The results suggest that the amide linkage plays a key role in the formation of a π‐conjugated structure, which facilitates charge transfer and consequently offers good capacitance and cycling stability. Furthermore, to realize the practical feasibility, an asymmetric supercapacitor using a GA@UiO‐66‐NH2 positive electrode with Ti3C2TX MXene as the opposing electrode has been constructed. The cell is able to deliver a power density of up to 16 kW kg−1 and an energy density of up to 73 Wh kg−1, which are comparable to several commercial devices such as Pb‐acid and Ni/MH batteries. Under an intermediate level of loading, the device retained 88% of its initial capacitance after 10 000 cycles.
Continuous High‐Throughput Fabrication of Architected Micromaterials via In‐Air Photopolymerization

Published: December 2020

AbstractRecent advances in optical coding, drug delivery, diagnostics, tissue engineering, shear‐induced gelation, and functionally engineered rheology crucially depend on microparticles and microfibers with tunable shape, size, and composition. However, scalable manufacturing of the required complex micromaterials remains a long‐standing challenge. Here in‐air polymerization of liquid jets is demonstrated as a novel platform to produce microparticles and microfibers with tunable size, shape, and composition at high throughput (>100 mL h−1 per nozzle). The polymerization kinetics is quantitatively investigated and modeled as a function of the ink composition, the UV light intensity, and the velocity of the liquid jet, enabling engineering of complex micromaterials in jetting regimes. The size, morphology, and local chemistry of micromaterials are independently controlled, as highlighted by producing micromaterials using 5 different photopolymers as well as multi‐material composites. Simultaneous optimization of these control parameters yields rapid fabrication of stimuli‐responsive Janus fibers that function as soft actuators. Finally, in‐air photopolymerization enables control over the curvature of printed droplets, as highlighted by high‐throughput printing of microlenses with tunable focal distance. The combination of rapid processing and tunability in composition and architecture opens a new route toward applications of tailored micromaterials in soft matter, medicine, pharmacy, and optics.
Allopatry, hybridization, and reproductive isolation in Arctostaphylos

Published: December 2020

PREMISEHybridization plays a key role in introgressive adaptation, speciation, and adaptive radiation as a source of evolutionary innovation. Hybridization is considered common in Arctostaphylos, yet species boundaries are retained in stands containing multiple species. Arctostaphylos contains diploids and tetraploids, and recent phylogenies indicate two clades; we hypothesize combinations of these traits limit or promote hybridization rates.METHODSWe statistically analyzed co‐occurrence patterns of species by clade membership and ploidy level from 87 random 0.1 ha plots. We sampled multiple sites to analyze for percent hybridization based on morphology. Finally, phenophases were analyzed by scoring herbarium sheets for a large number of taxa from both clades as well as tetraploids, and second, surveying three field sites over two years for divergence in phenological stages between co‐occurring taxa.RESULTSMost taxa in Arctostaphylos are allopatric relative to other congenerics. When two taxa co‐occur, the patterns are a diploid with a tetraploid, or two diploids from different clades. When three taxa co‐occur, the pattern is two diploids from different clades and a tetraploid. Field and herbarium data both indicate flowering phenology is displaced between diploids from the two clades; one of the diploid clades and tetraploids overlap considerably.CONCLUSIONSThe two deep clades in Arctostaphylos are genetically distant, with hybrids rare or non‐existent when taxa co‐occur. Reproductive isolation between clades is enhanced by displaced flowering phenology for co‐occurring species. Within clades, taxa appear to have few reproductive barriers other than an allopatric distribution or different ploidy levels.
Lack of a relationship between vitamin D status and resting metabolic rate in Iranian adults

AbstractObjectivesStudies suggest a positive relationship between 25‐hydroxy vitamin D (25(OH)D)) and resting metabolic rate (RMR). We aimed to determine whether this relationship was also true of populations with very low vitamin D status.MethodsFat mass (FM) and fat free mass (FFM) were determined from multifrequency bioimpedance analysis (InBody 720, Korea). RMR was based on indirect calorimetry (Cortex Metalyser 3B, Germany). Fasting blood measurements of 25(OH)D concentration, glucose and triglycerides were measured. Data were analyzed separately on men and women by tertile of vitamin D status and multiple linear regression analysis.ResultsTwo hundred and sixty‐three subjects (115 males; 148 females) with a mean age of 37 years and mean %body fat of 30.5% were studied. In women but not men, age, body weight, waist circumference, FM, and FFM increased significantly across tertiles of 25(OH)D. However, there was no difference in unadjusted or adjusted RMR across tertiles of 25OHD in both women and men. Stepwise forward regression analysis showed that age and FFM in men, age and FM in women but not by 25(OH)D, were determinants of RMR. In addition, RMR adjusted for age, sex, FM, FFM and triglyceride‐glucose index did not relate to 25(OH)D when linear (r = 0, P = .98), quadratic (r = 0.008, P = .34), or cubic (r = 0.010, P = .43) relationships were tested.ConclusionsResidual variation in RMR did not relate to vitamin D status in a group of Iranian adults with very low vitamin D status. Future studies could examine whether such a relationship holds true, after the normalization of vitamin D status.
