Primeros estudios arqueológicos y sedimentológicos de un contexto estratigráfico en el interior entrerriano. El sitio Laguna del Negro 1.
Authors: Apolinaire Eduardo , Castiñeira Latorre Carola
Published: February 2020

Los sitios arqueológicos detectados hasta el momento en las tierras altas de Entre Ríos se ubican principalmente en las fajas aluviales de los principales cursos fluviales que drenan el interior de la provincia. La mayor parte de estos sitios corresponden a contextos superficiales compuestos principalmente de restos de alfarería y algunos fragmentos líticos. En este trabajo se presentan las investigaciones geoarqueológicas llevadas a cabo en un contexto en estratigrafía del interior entrerriano, el sitio Laguna del Negro 1. A través de estos estudios fue posible explorar la vinculación de los asentamientos prehispánicos con la dinámica fluvial de los grandes cursos de agua de llanura. Además, se presenta aquí el análisis de un amplio conjunto cerámico, que ha permitido delinear las cadenas operativas de producción de alfarería en el área de estudio, así como contextualizar los hallazgos superficiales de este tipo de materiales.

En el río Uruguay inferior en la provincia de Entre Ríos (Argentina) los estudios arqueológicos de alta resolución sobre el origen y la evolución de los montículos o “cerritos” son muy recientes. En este marco se presentan y discuten los resultados de los estudios geoarqueológicos y cronológicos realizados en la localidad arqueológica Cerros de Boari, conformada por tres montículos: Cerro de Boari 1, 2 y 3, emplazados sobre un albardón paralelo a la margen izquierda del río Gualeguaychú. El análisis de la secuencia estratigráfica de los montículos permitió identificar dos sistemas depositacionales con caracteres texturales y composicionales claramente distinguibles. Un sistema natural de depositación fluvial que generó el albardón, constituido por depósitos Areno fangosos, Areno limosos a Limo arenosos y arqueológicamente estériles; y otro sistema de origen y evolución antrópica constituido por una sucesión de depósitos Areno fangosos ligeramente gravillosos con alto contenido de materia orgánica e innumerables vestigios arqueológicos. Los resultados cronológicos obtenidos para los depósitos basales del sistema depositacional antrópico permitieron reconocer que en la localidad arqueológica Cerros de Boari la arquitectura en tierra con fines domésticos y funerarios data de aproximadamente 2000 años AP, constituyendo uno de los registros más tempranos para el Nordeste argentino.
Análisis integral del sistema tecnológico cerámico del sitio arqueológico Guayacas (Paysandú, Uruguay)
Authors: Capdepont Caffa1 Irina
Published: February 2020

En el presente trabajo se exponen los estudios realizados sobre el material cerámico proveniente del sitio Guayacas. El sitio se encuentra ubicado en una lomada sobre el río Daymán (Paysandú – Uruguay). El registro arqueológico recuperado evidencia distintos tipos de actividades domésticas desarrolladas en un campamento residencial. Centrando el estudio en la alfarería, se profundiza en el conocimiento de la cadena técnica operativa, en los modos de aprovisionamiento y explotación de los recursos empleados en la manufactura, así como también en el uso y reciclado de las vasijas durante el Holoceno tardío. Los análisis tecnológicos, morfológicos, funcionales, estilísticos y cronológicos de la cerámica han permitido reconocer la historia de vida de las vasijas. La obtención de la materia prima ha sido local, encontrándose en áreas fuentes próximas al campamento. La técnica de manufactura correspondió, mayoritariamente, a la elaboración por rodete y la cocción se realizó a cielo abierto. Los análisis morfológicos y biocomposicionales permiten discriminar la variabilidad funcional de la alfarería en cuanto al tratamiento de alimentos vegetales para su preparación, cocción y consumo. Las decisiones técnicas y estilísticas implementadas hace aproximadamente 500 años atrás por parte de grupos cazadores, recolectores, pescadores y horticultores ribereños que ocuparon el sitio Guayacas, comparten caracteres con la alfarería de otros grupos de las tierras bajas sudamericanas.
Reconstrucción de vasijas asociadas al contexto funerario del sitio Los Tres Cerros 1 (Delta Superior del Río Paraná).
Authors: Castro Canela
Published: February 2020

En este trabajo se presentan los resultados derivados de la reconstrucción de formas y el análisis de huellas de uso y alteración de las vasijas asociadas a los entierros del sitio arqueológico Los Tres Cerros 1 (LTC1). LTC1 es una estructura monticular de origen antrópico, denominada regionalmente como “cerrito”, que fue habitada por grupos cazadores, recolectores, pescadores y horticultores a pequeña escala entre circa 1227 y 560 años AP. En el sitio se identificaron dos sectores: la cima del montículo donde se desarrollaron diversas actividades relacionadas con la ocupación de la estructura y un núcleo de inhumación de entierros humanos en la ladera este del montículo, en la intersección con la planicie. Con los objetivos de reconstruir los artefactos originalmente manipulados por los ceramistas e identificar las funciones desempeñadas por la alfarería en contextos domésticos y funerarios, se realizaron remontajes y se relevaron patrones de distribución de las huellas producidas por el uso de los contenedores. Estos estudios fueron complementados con el análisis de las partículas biosilíceas adheridas a las paredes de los recipientes como proxies reconocidos en la literatura arqueológica regional para el establecimiento de estrategias de manufactura y uso de las vasijas. La integración de los resultados de estas líneas de evidencia permitió inferir que las vasijas fueron utilizadas en actividades domésticas (cocción y servicio de alimentos), pero que en los últimos momentos de sus historias de vida adquirieron una función funeraria, al ser depositadas y fragmentadas en asociación con entierros humanos.
Marcadores de etnicidad y agencia en las pautas alimenticias. Su abordaje desde la Zooarqueología Histórica
Authors: Colasurdo María Belén
Published: February 2020

A partir del análisis de los restos óseos de fauna en sitios históricos se pueden indagar diferentes temas de investigación relacionadas con la alimentación,  como etnicidad, interacción entre poblaciones nativas e inmigrantes y agencia. El objetivo de este trabajo es presentar las inferencias realizadas en cuatro sitios arqueológicos de la ciudad de Rosario, correspondientes a los siglos XVIII y XIX: Casa Parroquial, Juan Manuel de Rosas, La Basurita y Arenales. La particularidad de los mismos radica en que corresponden cronológicamente con la masiva llegada de inmigrantes hacia mediados del siglo XIX y el consiguiente crecimiento de la ciudad con el pasaje de los siglos. La hipótesis es que estos cambios se reflejaron en el registro arqueológico, tanto en las especies preferidas para el consumo como en las formas de prepararlos. Si bien la evidencia no es concluyente, ya que se deben atender a otros factores, algunas inferencias como la mayor presencia de consumo de ovejas por sobre el de vacas para el final del período, la diversificación de los tipos de platos preparados, nos hablan de la interacción entre pobladores de distintos orígenes que puede haber permitido una síntesis de pautas alimentarias.

Published: February 2020

El asentamiento español de Sancti Spiritus se estableció en algún momento indeterminado entre mayo y agosto de 1527 en la confluencia de los ríos Carcarañá y Coronda, cuando arribó una expedición al mando de Sebastián Caboto. Este sitio arqueológico marca el inicio de la presencia europea en la región y con ello la introducción de nuevas especies vegetales. Los resultados obtenidos a partir del análisis de los fitolitos y los carbones arqueológicos del sitio contribuyen con información novedosa debido a que en ambos casos se identificaron vegetales introducidos en un contexto hispano-indígena de principios del siglo XVI. Los carbones debieron ser introducidos por los colonizadores, dado que fueron asignados a gimnospermas afines a pino silvestre (Pinus sylvestris) y tejo (Taxus baccata). La presencia de gimnospermas en un sitio arqueológico argentino representa la evidencia material más antigua de maderas de origen exótico en  momentos históricos. Las asociaciones fitolíticas identificadas responden a vegetales afines a gramíneas locales (Maideae y Oryzoideae) y un tipo de vegetal introducido, como es el caso de las formas afines a trigo (Triticeae). Los análisis arqueobotánicos aportan información que sumada a los registros históricos, proporcionan elementos para la reconstrucción de este acontecimiento relevante para la historia hispanoamericana.

Internal Structure and CO2 Reservoirs of Habitable Water Worlds
Authors: Marounina Nadejda , Rogers Leslie A.
Published: February 2020

Water worlds are water-rich (>1 wt% H2O) exoplanets. The classical models of water worlds considered layered structures determined by the phase boundaries of pure water. However, water worlds are likely to possess comet-like compositions, with between ∼3 and 30 mol% CO2 relative to water. In this study, we build an interior structure model of habitable (i.e., surface liquid ocean–bearing) water worlds using the latest results from experimental data on the CO2–H2O system to explore the CO2 budget and localize the main CO2 reservoirs inside of these planets. We show that CO2 dissolved in the ocean and trapped inside of a clathrate layer cannot accommodate a cometary amount of CO2 if the planet accretes more than 11 wt% of volatiles (CO2 + H2O) during its formation. If the atmosphere holds more than a negligible amount of the CO2 (>0.01% of the planet mass), the planet will not have a habitable surface temperature. We propose a new, potentially dominant, CO2 reservoir for water worlds: CO2 buried inside of the high-pressure water ice mantle as CO2 ices or (H2CO3 · H2O), the monohydrate of carbonic acid. If insufficient amounts of CO2 are sequestered in either this reservoir or the planet’s iron core, habitable-zone water worlds could generically be stalled in their cooling before liquid oceans have a chance to condense.
Interplanetary Coronal Mass Ejections as the Driver of Non-recurrent Forbush Decreases

Published: February 2020

Interplanetary coronal mass ejections (ICMEs) are the counterparts of coronal mass ejections (CMEs) that extend in the interplanetary (IP) space and interact with the underlying solar wind (SW). ICMEs and their corresponding shocks can sweep out galactic cosmic rays (GCRs) and thus modulate their intensity, resulting in non-recurrent Forbush decreases (FDs). In this work, we selected all FDs that were associated with a sudden storm commencement (SSC) at Earth, and a solar driver (e.g., CME) was clearly identified as the ICME’s source. We introduce and employ the tH
parameter, which is the time delay (in hours) of the maximum strength of the interplanetary magnetic field from the FD onset (as is marked via the SSC), and consequently derive three groups of FD events (i.e., the early, medium, and late ones). For each of these we examine the mean characteristics of the FDs and the associated IP variations per group, as well as the resulting correlations. In addition, we demonstrate the outputs of a superposed epoch analysis, which led to an average time profile of the resulting FDs and the corresponding IP variations, per group. Finally, we interpret our results based on the theoretical expectations for the FD phenomenon. We find that both the shock sheath and the ejecta are necessary for deep GCR depressions and that the FD amplitude (A0) is larger for faster-propagating ICMEs. Additionally, we note the importance of the turbulent shock-sheath region across all groups. Finally, we present empirical relations connecting A0 to SW properties.
GW170817A as a Hierarchical Black Hole Merger

Published: February 2020

Despite the rapidly growing number of stellar-mass binary black hole mergers discovered through gravitational waves, the origin of these binaries is still not known. In galactic centers, black holes can be brought to each others’ proximity by dynamical processes, resulting in mergers. It is also possible that black holes formed in previous mergers encounter new black holes, resulting in so-called hierarchical mergers. Hierarchical events carry signatures such as higher-than-usual black hole mass and spin. Here we show that the recently reported gravitational-wave candidate, GW170817A, could be the result of such a hierarchical merger. In particular, its chirp mass ∼40 M
⊙ and effective spin of χ
eff ∼ 0.5 are the typically expected values from hierarchical mergers within the disks of active galactic nuclei. We find that the reconstructed parameters of GW170817A strongly favor a hierarchical merger origin over having been produced by an isolated binary origin (with an odds ratio of > 103).
Antibacterial Activity of Mucoadhesive Gastroretentive Drug Delivery System of Alginate Beads Containing Turmeric Extract - PVP Solid Dispersion
Authors: Bangun Hakim , Arianto Anayanti , Bangun Yuni Sari , Nainggolan Marline
Published: February 2020

BACKGROUND: Turmeric extract is less effective because the main ingredient of curcumin has a low solubility. Therefore, it is necessary to convert turmeric extract into a solid dispersion form to increase the dissolution of curcumin.
AIM: To determine the antibacterial activity of mucoadhesive gastroretentive drug delivery system of alginate beads containing solid dispersion of turmeric extract.
METHODS: Turmeric powder was macerated with 96% ethanol for 8 days. The macerate was evaporated with a rotary evaporator at 50°C to obtain concentrated extract. Solid dispersion of turmeric extract was prepared by solvent method by using polyvinylpyrrolidone (PVP) K30 with a ratio of 1: 1 and 1: 2. The solid dispersion of turmeric extract was encapsulated with alginate gel by gelation method. The antibacterial of alginate beads containing solid dispersion of turmeric extract was tested by using hole agar plate diffusion method against Staphylococcus aureus and Escherichia coli as bacterial models.
RESULTS: The size of alginate beads containing turmeric extract-PVP solid dispersion was about 1.3 mm. Antibacterial activity test against Staphylococcus aureus and Escherichia coli showed that alginate beads containing turmeric extract-PVP solid dispersion gave stronger antibacterial activity than those containing turmeric extract without solid dispersion. The antibacterial activity of alginate beads turmeric extract-PVP (1: 2) solid dispersion was stronger than those containing turmeric-extract (1: 1) solid dispersion.
CONCLUSION: Based on the results of this study it can be concluded that alginate beads containing turmeric extract-PVP solid dispersion gives the stronger antibacterial activity than those containing turmeric extract without solid dispersion.

Published: February 2020

The orchid tribe Tropidieae comprises three genera, Tropidia, Corymborkis and Kalimantanorchis. There are three fully mycoheterotrophic species within Tropidieae: Tropidia saprophytica, T. connata and Kalimantanorchis nagamasui. A previous phylogenetic study of K. nagamasui, based only on plastid matK data, placed K. nagamasui outside the clade of Tropidia and Corymborkis without support. In this study, we performed phylogenetic analyses using a nuclear ribosomal DNA spacer (ITS1-5.8S-ITS2), a low-copy nuclear coding gene (Xdh) and a mitochondrial intron (nad1b-c intron) to study the phylogenetic relationships within Tropidieae. We included six photosynthetic and all three fully mycoheterotrophic Tropidieae species. The resulting phylogenetic trees placed these fully mycoheterotrophic species inside the Tropidia clade with high support. In our trees, these three species do not form a monophyletic group together, because the photosynthetic T. graminea is nested amongst them. Our results also suggest that the loss of photosynthetic ability occurred at least twice in Tropidia.
Le marché des bovins de trait dans un bourg de la Castille moderne :
Authors: Poujade Patrice
Published: February 2020

Almodóvar del Pinar, bourg de Nouvelle-Castille, accueille à l’époque moderne une bonne proportion de charretiers parmi ses habitants. Cette activité de transport y avait généré de nombreux échanges de bovins de trait dont les sources notariales ont enregistré les traces. En premier lieu, il s’agit de jeunes animaux, des novillos , mais aussi des paires de bœufs, le plus souvent avec leurs charrettes, qui changeaient de mains. Si, au xvii e  siècle, le marché est localement très animé particulièrement durant les mois d’août, il s’essouffle dès les premières décennies du xviii e  siècle. Cette évolution est matière à interrogation car, dans le même temps, l’activité des charretiers ne s’interrompt pas pour autant. La provenance des animaux met en lumière des spécialisations régionales bien marquées qui, en quelques mots, opposent nettement les zones, plus éloignées, fournissant les novillos , et celles, bien plus proches géographiquement, d’où viennent les bœufs, un peu comme si deux marchés distincts fonctionnaient en parallèle.
Le progrès agricole par l’exemple
Authors: Vulliod François
Published: February 2020

Avant le développement de l’enseignement agricole et la création d’organismes professionnels, la diffusion du savoir agronomique et des innovations reposait, pour la plupart des exploitants agricoles, sur l’imitation des progrès réalisés par ceux d’entre eux qui disposaient de moyens suffisants pour apprendre et expérimenter. Nous évoquons dans cet article trois très grands propriétaires de la Manche qui, entre  1820 et  1835 , reprirent en faire-valoir direct tout ou partie de leurs terres, afin d’y développer les pratiques agricoles innovantes que leurs lectures et leurs voyages d’étude avaient pu leur inspirer. L’un d’entre eux développa une exploitation hors du commun, en procédant à une transformation de ses productions végétales de façon à accroître la valeur ajoutée de ses produits et à disposer de résidus lui permettant de développer son cheptel. Ils se donnèrent l’objectif de diffuser le progrès autour d’eux par l’exemple, en évitant à leurs fermiers ou à leurs voisins d’avoir à supporter les coûts d’expérimentation. Ils rédigèrent dans ce but des notices destinées à faire largement connaître les pratiques qu’ils avaient développées.
A multivariate statistical analysis to determine catch intention in the pink cusk-eel (Genypterus blacodes) longline fishery in southern Chile

Published: February 2020

The definition of catch intention in multispecies fisheries is a key step toward building abundance indexes based on commercial fishing data. Previous analysis to determine catch intention in the pink cusk-eel (Genypterus blacodes) has been based on the idea that fishing tactics remain constant over time (static fishing tactics). We propose a statistical procedure to determine the catch intention of each haul in the industrial longline fisheries in southern Chile, where fishing tactics may vary over time. This procedure is based on principal component analysis and agglomerative hierarchical analysis of the catch composition, and relaxes the assumption of static fishing tactics by selecting a subset of data that is informative for fishing intention (target versus by-catch) every year. Sensitivity analyses were conducted to assess the robustness of variable fishing tactics on the nominal catch rates in pink cusk-eel. Targeted and by-catch time series of nominal catch rates showed a different trend, so determining the catch intention became relevant. Sensitivity analyses showed that trends in targeted catch rates are robust to the variations of fishing tactic per year. We recommend the use of variable fishing tactics for further use in effort standardization and stock assessment of the pink cusk-eel fishery in southern Chile.

Authors: Seya Keisuke , Kobayashi Nobuyuki , Shirasaka Seiko
Published: February 2020

The need to learn emerging technologies such as artificial intelligence is increasingly important not only for technical people but also for non-technical people. Previous studies showed the effectiveness of a story-based teaching method for both technical and non-technical people who want to learn emerging technologies. However, the difference between the story-building methods for technical people and non-technical people is not revealed. The purpose of this research is to pro-pose perspectives that reveal the differences in the stories used for emerging technology education and identify the effective story features suited for non-technical adult learners by comparing the different story-building methods used for technical people and non-technical people. In this study, we classified the story types into two perspectives: "past to present" and "present to future" and compared the two story-building methods in these perspectives. The novelty of this research is that the proposal of perspectives that reveal the differences in the stories used for emerging technology education and that we have identified the features of one of the effective stories suited for non-technical adult learners. We al-so examined the possibility of leveraging such differences in solving the issues that a class of non-technical people called conversational programmers is facing.

Authors: Aznar-Díaz Inmaculada , Hinojo-Lucena Francisco-Javier , Cáceres-Reche María-Pilar , Romero-Rodríguez José-María
Published: February 2020

Dialogical learning and teamwork have become the principles demanded by the knowledge society, given that we are currently living in a completely globalised world that requires skilled citizens to collaborate on a social, pro-fessional and academic level. Likewise, creativity is another key element re-quested by organisations to solve problems. Against this background, some student-centred teaching methods like flipped classrooms are appearing. Therefore, this paper aimed to analyse the implementation of the flipped classroom method as a factor to develop dialogical learning and creativity. To this regard, a quantitative method was used, applying a survey prepared ad hoc to a sample of 308 students from Spain and Colombia, in order to know whether implementing the flipped classroom truly enhances the develop-ment of such skills. According to the results obtained, it is stated that devel-oping the flipped classroom method promotes a team-based work dynamic, which generates dialogical learning among students. It also enhances creativ-ity, since it provides students with autonomy to carry out their tasks. Final-ly, the flipped classroom pedagogical approach is a teaching method with numerous advantages and benefits for students to adapt to the competencies required by the knowledge society.

Authors: Lim Chee Leong , Ab Jalil Habibah , Ma'rof Aini Marina , Saad Wan Zuhainis
Published: February 2020

The ability for students to self-regulate their learning and to learn effectively with peers become two distinctive competencies in the era of the 4th Industrial Revolution. These competencies also affect academic achievement, an important variable used to measure attainment of learning outcomes. Therefore, this study was conducted to determine the influence of peer learning and self-regulated learning (SRL) strategies on students’ academic achievement. Of the 409 respondents, only 347 were valid for data analysis, forming a usable case of 84.84%. The instruments used was an online questionnaire, which was adapted from pre-existing reliable multi-item instruments. Structural Equation Model (SEM) analysis was used to examine the relationship between the constructs in the hypothesised model. Given that the structural model exhibited a good fit to the data (χ2/df = 1.697; CFI = 0.916; IFI = 0.917; TFI = 0.912; and RMSEA = 0.045), the results unveiled that students’ ability to learn with peers were found to have a positive and significant effect on academic achievement (β = 0.478, C.R. = 3.628, p = 0.000), and significantly influenced students’ SRL strategies (β = 0.793; C.R. = 6.991; p = 0.000). This study also discusses the practical implications to facilitate the development of students’ self-regulated learning (SRL) and peer learning competencies in blended learning courses.
A Probe into Spoken English Recognition in English Education Based on Computer-Aided Comprehensive Analysis
Authors: Wang Yongjuan , Zhao Peng
Published: February 2020

At present, computer-aided spoken English learning is becoming increasingly popular among learners. The computer-aided comprehensive analysis tech-nology can evaluate and correct learner's spoken pronunciation, thereby im-proving their pronunciation. Based on computer-aided comprehensive analy-sis, this paper aims to explore the automatic recognition and scoring methods of spoken English in English education. For this, it studies the effective matching of the feedback information with the known pronunciation scoring results, and then develops a computer evaluation plug-in consisting of dif-ferent modules such as user login, English spoken speech acquisition and recognition, voice evaluation, speech broadcast, and spoken dialogue. The research results show that the computer evaluation plug-in matches and compares the extracted feature parameters of input speech with the standard features, scores the spoken language input by the learner, and gives the cor-rect pronunciation so that the learner can get feedback in time. For different stages of English learning, the focus of recognition technology and the spo-ken recognition algorithms applied also vary. The research findings provide theoretical and technical support for oral English recognition, error correction and scoring.

Published: February 2020

The concept of Higher-Order Thinking Skills (HOTS) is one of the highlighted aspects in producing human capital of high quality. However, the level of HOTS among students in Malaysia is still at a lower stage. Among the causes of this problem is the learning strategy used in classroom, which is less effective in creating and enhancing HOTS optimally. Therefore, the main focus in this study was to investigate the potential role of an inductive reasoning strategy using Geogebra in increasing the students’ level of HOTS. Besides, it also aimed to identify the relationship between HOTS and students’ inductive reasoning for the topic of Graphs of Functions II. The design of study was quasi-experimental which involved 94 form-four students from a secondary school in Johor. The sample of this study was divided into three groups: (1) Treatment Group 1 (inductive reasoning strategy using Geogebra); Treatment Group 2 (inductive reasoning strategy); and (3) a control group (conventional). The instrument of the study comprised a set of HOTS questions and a worksheet based on an inductive reasoning strategy using Geogebra. Using the Multivariate Analysis of Variance (MANOVA), it was found that the overall HOTS level of the students, which included applying, analysing, evaluating and creating skills, could be enhanced through this strategy. The findings also show that there was a positive relationship between HOTS and inductive reasoning. In conclusion, an inductive reasoning strategy can provide positive impacts on students’ HOTS in the topic of Graphs of Functions II
Engagement militant et phénomènes de radicalisation chez les Kurdes de Turquie
Authors: Dorronsoro Gilles , Grojean Olivier
Published: February 2020

Why and how do people engage in a radical movement? To answer this question, this paper analyses two Kurdish movements in Turkey, the PKK and the Hizbullah, under three different aspects. First, the constitution of radical groups is explained as a way for political entrepreneurs without social and economic capital to mobilize ressources. Radicalisation is also results of the competition with others groups belonging to the same political field. Secondly, personal dispositions are actualised during the process of adhesion. Here, the first group of militants linked by strong and multiple links has to be distinguished from the second generation, more likely to be made up by isolated individuals. Finally, the paper analyses two ways to bridge the old values of the primary socialization and the new world of the party: values such as charism and honor (namus) work in both universes and biographies (or autobiographies) allow individuals to recreate a coherence in their self-perception.
Qu’est-ce qu’un Turc ? (Égypte, Syrie, xvie siècle)
Authors: Lellouch Benjamin
Published: February 2020

L’article étudie les occurrences du mot « Turc » dans les sources arabes et turques, tout particulièrement les chroniques, écrites en Égypte et en Syrie ottomanes au xvie siècle. Il examine ce qu’elles définissent comme « turc » : les individus portant le nom « Le Turc », les réalités « turques » ou relevant des « Turcs », les qualités morales des « Turcs ». Puis il se penche sur les termes dont le contexte montre qu’ils désignent des groupes distincts des « Turcs », ou qu’au contraire ils se confondent avec ces derniers. Il en ressort que le « Turc » est un non-« Arabe », militaire ou plus généralement membre de la gent d’État (askeri), donc un Ottoman, même si « Turc » est beaucoup plus rare que « Roum ». Le mot a un accent élitaire, alors que comme on le sait, il désigne avant tout un rustre en Anatolie et dans les Balkans ; cette opposition n’est pas surprenante si l’on songe que déjà au Moyen-Âge les usages du terme étaient soit spécifiques, soit génériques, et les représentations des « Turcs » largement contradictoires. Des références comparatives à Alger et au Yémen laissent penser que la distinction d’avec les « Arabes » fut déterminante dans la construction de l’identité « turque » dans les provinces arabes de l’Empire ottoman.
Two Oriental Images of Istanbul: Robbe-Grillet’s L’Immortelle and Erksan’s Time to Love
Authors: Daldal Aslı
Published: February 2020

This essay aims at comparing Alain Robbe-Grillet’s L’Immortelle (1963) and Metin Erksan’s Time to Love (1966) in terms of their depiction of Istanbul that holds a central place within both films’ plots. Both films have been made in the aftermath of the 1960 coup d’état in Turkey which repositioned the ‘power’ of the capital city of Ankara and the modernist aspirations of the neo-Kemalist elites. So both Erksan and Robbe-Grillet are recreating the Ottoman past (as opposed to the aspirations of the neo-Kemalists) in peculiar Orientalist tropes. While the image they develop for the city is basically an ‘Oriental image’ that excludes the documentary, realistic aspects, their orientalism diverges greatly. Erksan wishes to retreat from the westernized modern life of Istanbul and thus sublimates old Eastern philosophical traditions to find some Platonic ‘truthfulness’ within the old imperial city. Robbe-Grillet, on the other hand, in search of the immortal passion and exoticism, recreates the Oriental ‘myth’ of Istanbul within a modernist guise. Robbe-Grillet’s parallel depiction of the femme fatale Leila with the mysterious city also contrasts to Erksan’s ‘Occidentalist’ emphasis upon the ‘nobility’ and ‘naivety’ of the lovers within the ‘sublimated’ image of the old imperial city, Istanbul or Dersaadet [the door of happiness].
Assimilation of the Muslim communities in the first decade of the Turkish Republic (1923-1934)
Authors: Ülker Erol
Published: February 2020

The aim of this paper is to demonstrate how immigration-settlement policies were employed by post-Lausanne Turkey to create a homogenous nation-state. Focusing on the incorporation of immigrants in the period of 1923-1934, the paper argues that the state policies of migration and settlement pursued two primary objectives that were closely connected with the nationalizing measures. They were carried out for the assimilation of non-Turkish-speaking Muslims on the one hand, and for the Turkification of Kurdish-populated eastern provinces on the other.
Explosive Boiling of Water on a Hot Copper Plate: A Molecular Dynamics Simulation Study
Authors: Bin Shahadat Muhammad Rubayat , Morshed A.K.M.M.
Published: February 2020

Non-equilibrium molecular dynamics simulations have been employed to study the explosive boiling phenomena of water over a hot copper plate. The molecular system was comprised of three sections: solid copper wall, liquid water, and water vapor. A few layers of the liquid water were placed on the solid Cu surface. The rest of the simulation box was filled with water vapor. Initially, the water molecules were equilibrated by using Berendsen thermostat at 298 K. Then heat was given to the copper plate at different temperatures so that explosive boiling occurs. After achieving the equilibrium by performing the previous two steps, the liquid water at 298 K is suddenly dropped on the hot plate. NVE ensemble was used in the simulation and the temperature of the copper plate was controlled to different temperatures with phantom atom thermostat. Four temperatures (400K, 500K, 650 K and 1000K) were taken to study the explosive boiling. The simulation results show that, the explosive boiling temperature of water on Cu plate is 500 K temperature. At this point, the energy flux was found 1.79x108 J/m3 which is very promising with the experimental results. Moreover, if the temperature of the surface was increased the explosive boiling occurred at a faster rate. The simulation results also show that explosive boiling occurs earlier for the hydrophilic surface than hydrophobic surface as for the hydrophilic surface the water attracted the Cu plate more than the hydrophobic surface and so the amount of energy transfer is more for the hydrophilic surface.
A Comprehensive Analysis and Review on Electrical Machines in Wind Energy Conversion Systems

Published: February 2020

Wind energy conversion systems (WECS) have developed rapidly in recent years in terms of capacity and wind turbines design. This development led to improve power quality, to reduce the costs and increase the energy yield. WECS are expected to be reliable, effective and more cost-competitive. A comprehensive analysis and review on electrical machines in WECS (viz., wind turbine generators) has been presented in this paper. Design, (dis) advantages, and market penetration of different wind turbine generators are analyzed and discussed. Some comparisons have been made on the permanent-magnet (PM) synchronous machines, promising generator for future wind turbines, especially offshore wind turbines.

Conceptualising social accountability as an attribute of medical education
Authors: Clithero-Eridon Amy , Albright Danielle , Ross Andrew
Published: February 2020

Background: Health professionals need to be both person- and community oriented to improve population health. For educators to create socially accountable physicians, they must move learners from understanding social accountability as an expectation to embracing and incorporating it as an aspect of professional identity that informs medical practice.Aim: The aim of this article was to assess the degree to which medical students, preceptors and community mentors understand the concept of social accountability.Setting: The setting is the KwaZulu-Natal Province in Durban, South Africa.Methods: Using an observational design, we surveyed 332 participants, including the first- and sixth-year medical students, physician preceptors and community mentors.Results: Whilst most respondents understood social accountability as requiring an action or set of actions, it was defined by some as simply the awareness one must have about the needs of their patients, community or society at large. Some respondents defined social accountability as multi-dimensional, but these definitions were the exception, not the rule. Finally, most respondents did not identify to whom the accountable party should answer.Conclusion: Whilst the development of professional identity is seen as a process of ‘becoming’, the ability to define and understand what it means to be socially accountable is not a linear process. Assessment of this progress may start with comprehending how social accountability is understood by students when they begin their education and when they are graduating, as well as in knowing how their educators, both clinical and community, define it.
On the Mechanism of Cathodic Protection and Its Implications on Criteria Including AC and DC Interference Conditions
Authors: Büchler Markus
Published: February 2020

In recent years, a wide agreement with respect to the processes associated with cathodic protection (CP) has been reached within the CP industry. The increase of the pH value at the steel surface and the generation of passivating conditions as a result of the CP current are widely accepted as the relevant underlying mechanism. Based on this understanding it was possible to identify the relevant processes with respect to AC and DC interference and explain the empirical observations. This led to the development of ISO 18086 and has significantly influenced the work on ISO/DIS 21857. This paper summarizes present state of knowledge, the more recent developments, and their implications with respect to the CP criteria. It summarizes the relevant aspects in association with interference conditions and highlights possible future approaches with respect to the assessment of the effectiveness of CP.
Applying Linguistics in Illness and Healthcare Contexts
Authors: Demjén Zsófia
Published: February 2020

All aspects of illness and healthcare are mediated by language: experiences of illness, death and healthcare provision are talked and written about (face-to-face or online), while medical consultations, research interviews, public health communications and even some diagnostic instruments are all inherently linguistic in nature. How we talk to, about and for each other in such a sensitive context has consequences for our relationships, our sense of self, how we understand and reason about our health, as well as for the quality care we receive. Yet, linguistic analysis has been conspicuously absent from the mainstream of medical education, health communication training and even the medical or health humanities.

The chapters in this volume bring together applied linguistic work using discourse analysis, corpus methods, conversation analysis, metaphor analysis, cognitive linguistics, multiculturalism research, interactional sociolinguistics, narrative analysis, and (im)politeness to make sense of a variety of international healthcare contexts and situations. These include:

-clinician-patient interactions

-receptionist-patient interactions

-online support forums

-online counselling

-public health communication

-media representations

-medical accounts

-diagnostic tools and definitions

-research interviews with doctors and patients

The volume demonstrates how linguistic analysis can not only improve understandings of the lived-experience of different illnesses, but also has implications for communications training, disease prevention, treatment and self-management, the effectiveness of public health messaging, access to appropriate care, professional mobility and professional terminology, among others..
Shameful Bodies
Authors: Lelwica Michelle Mary
Published: February 2020

What happens when your body doesn’t look how it’s supposed to look, or feel how it’s supposed to feel, or do what it’s supposed to do? Who or what defines the ideals behind these expectations? How can we challenge them and live more peacefully in our bodies?

Shameful Bodies: Religion and the Culture of Physical Improvement explores these questions by examining how traditional religious narratives and modern philosophical assumptions come together in the construction and pursuit of a better body in contemporary western societies. Drawing on examples from popular culture such as self-help books, magazines, and advertisements, Michelle Mary Lelwica shows how these narratives and assumptions encourage us to go to war against our bodies—to fight fat, triumph over disability, conquer chronic pain and illness, and defy aging. Through an ethic of conquest and conformity, the culture of physical improvement trains us not only to believe that all bodily processes are under our control, but to feel ashamed about those parts of our flesh that refuse to comply with the cultural ideal. Lelwica argues that such shame is not a natural response to being fat, physically impaired, chronically sick, or old. Rather, body shame is a religiously and culturally conditioned reaction to a commercially-fabricated fantasy of physical perfection.

While Shameful Bodies critiques the religious and cultural norms and narratives that perpetuate external and internalized judgment and aggression toward “shameful” bodies, it also engages the resources of religions, especially feminist theologies and Buddhist thought/practice, to construct a more affirming approach to health and healing—an approach that affirms the diversity, fragility, interdependence, and impermanence of embodied life.
