LET’S HEAR IT ONCE MORE FOR THE UNSUNG COACH: ON THE EFFICIENCY OF COACHING FOR THE UNIFIED STATE EXAM
Authors: Nurieva L. M. , Kiselev S. G. 
Published: November 2018

Introduction. With the introduction of a new attestation procedure of school graduates in the form of the Unified State Examination (USE), coaching has gained widespread acceptance in Russia. By some estimates, between a quarter and a half of school graduates have recourse to one-to-one coaching when preparing for the USE. However, the question of the efficiency of such lessons remains open. Recently, various publications in professional periodicals and the media have begun to appear, which cast doubt on the benefits of coaching. The authors of these publications are specialists of the Higher School of Economics (HSE). According to their studies, additional lessons in preparing for the USE, including those with coaches, have a very little effect. Theaimof the research was to discuss the validity of the HSE specialists’ arguments concerning the low efficiency of coaching activities.Methodology and research methods. In the course of studying the problem, a comprehensive research methodology was applied, including approaches for comparative and statistical analysis of data and materials published by the HSE, Federal Institute of Pedagogical Measurements (FIPI) and Federal Testing Centre.Results and scientific novelty. An analysis of scientific works published by the HSE specialists showed that their conclusions with regard to the claimed low efficiency of additional lessons in preparation for the USE are unsubstantiated due to the presence of gross methodological errors in the calculations. Firstly, the students’ initial level of knowledge prior to lessons with a coach was miscalculated, with the final school grades in Russian language and mathematics being taken as the initial level instead of the average score of the certificate. Secondly, the specialists ignored the fact that the final grade “two” does not exist in the school attestation system. In this regard, the models used by the HSE specialists’ did not allow the progress in training from the school grade “three” to the USE “three” evaluation to be adequately recognised. Thirdly, the determination of the efficiency of coaching was made without taking the specific character of different teaching disciplines into account. Thus, the reliance on formal mathematical procedures to the detriment of content problem analysis led the specialists of the HSE to snap judgements that do not reflect the true situation.Practical significance.The authors believe that the observations provided in this paper will help education specialists to adjust approaches when determining the efficiency of additional lessons during USE preparation.
Origen y evolución arquitectónica de los conventos cordobeses de Madres Dominicas
Authors: Carmona Carmona Francisco Manuel 
Published: October 2018

A partir del análisis de la abundante información inédita que nos ofrecen tanto archivos como fondos con documentación conventual, en esta investigación hemos intentado destacar las distintas vías de origen y evolución arquitectónica de los claustros cordobeses de dominicas. Si tradicionalmente se ha venido vinculando únicamente la actividad fundadora y constructiva a determinadas clases privilegiadas, este estudio deja patente que el impulso de la comunidad femenina en las estructuras edilicias que permiten su reunión ha quedado olvidado o silenciado. Así, nos proponemos el triple objetivo de evidenciar el desconocimiento sobre las vías de origen, formación, desarrollo y defensa de las edificaciones conventuales; ponderar la importancia del impulso femenino para con ello; así como destacar el potencial de la documentación conventual para la Historia del Arte.
CORMAC McCARTHY’NİN İHTİYARLARA YER YOK ADLI ROMANINDA HETEROTOPİK MEKAN OLARAK SINIR BÖLGESİ
Authors: KOÇSOY F.gül 
Published: October 2018

Michel
Foucault (1926-1984) “Başka Mekanlara Dair” (1967) adlı konferans/makalesinde
Batı’daki mekan kavramının evrimini anlatır ve ütopya ile distopyadan farklı
olarak, varlığının tam anlamıyla anlaşılmadığı ve tanımlanmadığı ya da
yanılsamalı olarak anlaşıldığı yerleri heterotopya olarak nitelendirir. Foucault’ya göre toplumsal düzenin/anlayışın
bir arada olmasına izin vermediği öğelerin bir arada olduğu yerler olan
heterotopyalar, aslında aldatıcı bir düzen ve mantık hissi verirler. Örneğin
sınırlar, ideal anlamda oluşturulmuş yerleşim, hak ve düzen alanlarının
başlangıcını ve sonunu tanımlarlar; ancak gerçek anlamda geçirgendirler ve söz
konusu düzenin sürekli ihlal edildiği yerlerdir. Göreceli bir düzen imajı
sunmalarının yanı sıra, politik, kültürel ve etik düzenin sorgulanıp
yargılanmasına olanak tanıyan güçlerinden dolayı sınırlar heterotopik
yerlerdir.

Cormac
McCarthy‘nin (1933-) İhtiyarlara Yer Yok (2005) adlı romanı, Amerika Birleşik
Devletleri-Meksika sınırında geçer. Romanda, postmodern dönemde sınırların
artık devletler arasındaki hukuku belirleyici temel ya da ütopik niteliklerini
kaybettikleri ve distopya olmadan Foucault’nun deyimiyle heterotopya, yani
bunların dışındaki ‘başka’ mekanlara dönüştükleri ortaya çıkar.
Motivos para o Perfeccionismo e Intolerância à Frustração nos Estudantes de Medicina da Universidade de Coimbra

Published: October 2018

Introdução: O perfeccionismo e a intolerância à frustração são os principais fatores de vulnerabilidade ao stress psicológico nos estudantes do Mestrado Integrado em Medicina da Faculdade de Medicina da Universidade de Coimbra. Este estudo procurou investigar a causalidade dos mesmos para sua prevenção.Material e Métodos: Estudo observacional em triangulação, qualitativo-quantitativo, com inventariação dos principais motivos em painel de alunos, sendo a listagem obtida organizada e colocada em questionário complementado com inquérito epidemiológico, aplicado online a todos os alunos do Mestrado Integrado em Medicina da Faculdade de Medicina da Universidade de Coimbra, seguindo-se análise estatística.Resultados: Estudou-se amostra representativa, de n = 368, 77,7% do sexo feminino. Os principais motivos para perfeccionismo e intolerância à frustração são ’fatores intrínsecos‘ e ’exigências da profissão médica‘, com, respetivamente, 91,1% e 91,8% de respostas 'importante’ / ’muito importante‘; ’pressão ambiental‘ é o menos importante, com 68,2% em tais classificações. Alunos satisfeitos com a vida curricular atribuem menor importância à ’pressão ambiental‘ (p = 0,004), ‘insegurança quanto à formação profissional’ (p = 0,017), ‘métodos de avaliação curricular’ (p = 0,002) e ’exigências curriculares do Mestrado Integrado em Medicina‘ (p = 0,002); o sexo feminino dá maior importância às ’exigências curriculares do Mestrado Integrado em Medicina‘ (p = 0,001); alunos inseridos em atividade extracurricular, consideram menos importante a ’pressão ambiental‘ (p = 0,007).Discussão: Nesta amostra a vulnerabilidade ao stress psicológico por perfeccionismo e intolerância à frustração depende essencialmente da personalidade auto-exigente. Outro importante fator corresponde à insegurança relativamente às exigências profissionais, com sofrimento por antecipação e ausência de perspetiva profissional.Conclusão: O suporte psicológico, o envolvimento em atividades extracurriculares específicas e a reestruturação curricular parecem ser formas de diminuir a vulnerabilidade ao stress nos estudantes de medicina.
Special Issue on the Development of Disaster Statistics
Authors: Ono Yuichi , Sasaki Daisuke 
Published: October 2018

This special issue presents the findings obtained so far by the relevant studies that have been conducted mainly at the Global Centre for Disaster Statistics (GCDS), which is affiliated with the International Research Institute of Disaster Science (IRIDeS) at Tohoku University, Japan.
The establishment of the GCDS was jointly announced by the United Nations Development Program (UNDP) and the IRIDeS in March 2015 during the Third UN World Conference on Disaster Risk Reduction (UNWCDRR) in Sendai, Japan. The Centre is expected to contribute greatly to sustainable development, based on risk-informed policy making, through the following activities: providing scientific analyses and technical advice based on their disaster loss and damage data, supporting the United Nations International Strategy for Disaster Reduction (UNISDR) and individual countries in the work of monitoring the progress of the Sendai Framework for Disaster Risk Reduction (SFDRR) and the 2030 Agenda for Sustainable Development, and providing policy advice to build the capacities of national/local governments, based on their demands.
In this context, the guest editors of this special issue are pleased to publish valuable academic articles closely related to the GCDS’ activities that contribute to the development of disaster statistics. As Sasaki and Ono (2018) observed, there exist three major categories of research questions that contribute to the development of disaster statistics: investigation into disaster statistics and/or global disaster-related databases, development of the existing discipline-based research, and analysis of various issues through questionnaire surveys.
Last but not least, it is our hope that this special issue contributes to the literature of disaster statistics and accelerates its development.

Reservoir and Fracture-Flow Characterization Using Novel Diagnostic Plots

Published: November 2018

SummaryMultistage hydraulically fractured horizontal wells provide an effective means to exploit unconventional reservoirs. The current industry practice in the interpretation of field response often uses empirical decline-curve analysis or pressure-transient analysis/rate-transient analysis (PTA/RTA) for characterization of these reservoirs and fractures. These analytical tools depend on simplifying assumptions and do not provide a detailed description of the evolving reservoir-drainage volume accessed from a well. Understanding of the transient-drainage volume is essential for unconventional-reservoir and fracture assessment and optimization.In our previous study (Yang et al. 2015), we developed a “data-driven” methodology for the production rate and pressure analysis of shale-gas and shale-oil reservoirs. There are no underlying assumptions of fracture geometry, reservoir homogeneity, and flow regimes in the method proposed in our previous study. This approach depends on the high-frequency asymptotic solution of the diffusivity equation in heterogeneous reservoirs. It allows us to determine the well-drainage volume and the instantaneous recovery ratio (IRR), which is the ratio of the produced volume to the drainage volume, directly from the production data. In addition, a new w(τ) plot has been proposed to provide better insight into the depletion mechanisms and the fracture geometry. w(τ) is the derivative of pore volume with respect to τ.In this paper, we build upon our previous approach to propose a novel diagnostic tool for the interpretation of the characteristics of (potentially) complex fracture systems and drainage volume. We have used the w(τ) and IRR plots for the identification of characteristic signatures that imply complex fracture geometry, formation linear flow, partial reservoir completions, and fracture-interference/compaction effects during production. The w(τ) analysis gives us the fracture surface area and formation diffusivity, while the IRR analysis provides additional information on fracture conductivity. In addition, quantitative analysis is conducted using the novel w(τ) plot to interpret fracture-interference time, formation permeability, total fracture surface area, and stimulated reservoir volume (SRV).The major advantages of this current approach are the model-free analysis without assuming planar fractures, homogeneous formation properties, and specific flow regimes. In addition, the w(τ) plot captures high-resolution flow patterns not observed in traditional PTA/RTA analysis. The analysis leads to a simple and intuitive understanding of the transient-drainage volume and fracture conductivity. The results of the analysis are useful for hydraulic-fracturing-design optimization and matrix- and fracture-parameter estimation.
Calibration of a dynamic Eulerian-lagrangian model for the computation of wood cylinders transport in shallow water flow
Authors: Persi Elisabetta , Petaccia Gabriella , Sibilla Stefano , Brufau Pilar , García-Navarro Pilar 
Published: November 2018

Abstract
A computational Eulerian–Lagrangian model (ORSA2D_WT) is used for modelling the movement of floating rigid bodies on the water surface. The two-dimensional transport is computed with a dynamic approach, modifying existing formulations for the transport of bodies within fluid flows for the case of floating bodies, by adopting suitable added mass, drag and side coefficients. An original formulation for planar rotation is proposed, which includes the effect of the hydrodynamic torque and a resistance term, named added inertia, based on the difference between the angular velocity of the flow and that of the body. The value of the added inertia coefficient is calibrated against experiments made on purpose, involving the transport of a cylinder in a flume with two side obstacles. The calibrated code is applied to a slightly larger set of experiments for its preliminary evaluation. The outcome of the simulations shows that the streamwise and transversal displacements are well modelled, while some inaccuracies arise when considering the cylinder orientation. The effects of the initial conditions on the cylinders' trajectory and rotation are discussed, showing their influence on the evolution of the rotation angles.
Impacts of operational conditions on oxygen transfer rate, mixing characteristics and residence time distribution in a pilot scale high rate algal pond

Published: October 2018

AbstractDifferent combinations of operational parameters including water level, paddle rotational speed and influent flow rate were applied to investigate their impacts on mixing characteristics, residence time distribution and gas transfer rate in a pilot-scale high rate algal pond. In closed condition, the paddle rotational speed had a positive correlation with the Bodenstein number (Bo), water velocity and oxygen volumetric mass transfer coefficient (kLaO2) while increasing water level generated a negative impact on these parameters, although the impact of water level on water linear velocity was small. The amplification effect of water level and paddle rotational speed on the sensitivity of Bo and kLaO2 should be noticed. Moreover, paddle rotational speed had more impact on kLaO2 than on Bo. The study in open condition indicated that effective volume fraction had a positive correlation with inlet flow rate and negative correlation with paddle rotation, while the opposite was observed in the case of Peclet number. The impact of water level variation on these parameters was unclear. Both water level and paddle rotational speed had negative impacts on the short-circuiting index, while no correlation was observed when varying inlet flow rate. In this study, the optimal operational conditions included low water level (0.1 m) and medium paddle rotational speed (11.6 rpm).
Transport of chromium(III) from mixtures of chromium ions by CTA- and PVC-based inclusion membranes
Authors: Rajewski J. 
Published: October 2018

Abstract
The author analysed the stability of cellulose triacetate (CTA)- and poly(vinyl chloride) (PVC)-based polymer inclusion membranes (PIMs) containing bis(2-ethylhexyl) phosphoric acid (D2EHPA) as a carrier for chromium(III) separation from mixtures of Cr(III)/Cr(VI) ions. He also studied the influence of carrier (D2EHPA) concentration in PVC- and CTA-based PIMs on chromium(III) ion transport, at different initial concentrations of the Cr(III) ions. Based on the results, the optimum range of carrier concentration in both membranes guaranteeing the fastest process was found. Moreover, PIMs with D2EHPA as the carrier worked as selective barriers for Cr(VI) ions. However, in the case of CTA/PIM, the increase in Cr(VI) concentration above 0.005 mol/dm3 negatively influenced Cr(III) transport, which was caused by the degradation of the polymer matrix. The PVC/PIM was not influenced by the Cr(VI) ions, thus PVC was definitely a better polymer for the synthesis of PIM for the separation of Cr(III/VI) ions. It was also demonstrated that both membranes were not stable over a long process time. The results reported in this study suggest that the factor that determines the stability of PIMs with D2EHPA is the presence of water in the membrane and the formation of unstable micellar structures.
