Global database of oceanic particulate organic carbon to 234Th ratios: Improving estimates of the biological carbon pump
Authors: Puigcorbé Viena , Masqué Pere , Le Moigne Fréderic A. C.
Published: February 2020

Abstract. The ocean's biological carbon pump (BCP) plays a major role in the global earth carbon cycle. A fraction of the photosynthetically fixed organic carbon produced in surface waters is exported below the sunlit layer in the form of settling particles (e.g. marine snow). Since the seminal works on the BCP, global estimates of the global strength of the BCP have improved but large uncertainties remain (from 5 to 20 GtC yr−1 exported below the euphotic zone or mixed layer depth). The 234Th technique is widely used to measure the downward export of particulate organic carbon (POC). This technique has the advantage to allow a downward flux to be determined by integrating the deficit of 234Th in the upper water column and coupling it to an estimate of the POC/234Th ratio in sinking matter. However, the factors controlling the regional, temporal and depth variations of POC/234Th ratios are poorly understood. We present a database of 9110 measurements of the POC/234Th ratio in the ocean, from the surface down to > 5500 m, sampled on three size fractions (~ > 0.7 μm, ~ 1–50 μm, ~ > 50 μm), collected with in situ pumps and bottles, and also from bulk particles collected with sediment traps. The dataset is archived on the data repository PANGAEA® (https://www.pangaea.de/) under https://doi.pangaea.de/10.1594/PANGAEA.902103 (Puigcorbé, 2019). The samples presented in this dataset were collected between 1989 and 2016 and the data have been obtained from published papers and open datasets available online. Unpublished data has also been included. Most of the open ocean provinces are represented by multiple measurements. However, there is an uneven distribution of the data, with some areas highly sampled (e.g, China Sea, Bermuda Atlantic Time Series station) compared to some others that are not well represented, such as the southeastern Atlantic, the south Pacific and the south Indian oceans. Some costal areas, although in a much smaller number, are also included in this global compilation. Globally, based on different depths horizons and climate zones, the median POC/234Th ratios have a wide range, from 0.6 to 18 μmol dpm-1.
Assessing global water mass transfers from continents to oceans over the period 1948–2016
Authors: Cáceres Denise , Marzeion Ben , Malles Jan Hendrik , Gutknecht Benjamin , Müller Schmied Hannes , Döll Petra
Published: February 2020

Abstract. Continental water mass change affects ocean mass change (OMC). Assessing the net contribution, however, remains a challenge. We present an integrated version of the WaterGAP global hydrological model that is able to simulate total continental water storage anomalies (TWSA) over the global continental area (except Greenland and Antarctica) consistently by integrating the output from the global glacier model of Marzeion et al. (2012) as an input to WaterGAP. Monthly time series of global mean TWSA obtained with an ensemble of four variants of the integrated model, corresponding to different precipitation input and irrigation water use assumptions, were validated against an ensemble of four TWSA solutions based on GRACE satellite gravimetry over January 2003 to August 2016. The overall fit to GRACE, measured by the Nash–Sutcliffe efficiency (NSE) coefficient, was found to be 0.87. By decomposing the original TWSA signal into its seasonal, linear trend and inter-annual components, we find that the seasonal amplitude and phase are very well reproduced (NSE = 0.88), the linear trend is overestimated by 30–50 % (NSE = 0.65) and inter-annual variability is captured to a certain extent (NSE = 0.57) by the integrated model. During the period 1948–2016, we find that continents lost 34–41 mm of sea level equivalent (SLE) to the oceans, with global glacier mass loss accounting for 81 % of the cumulated mass loss and glacier-free land water storage anomalies (LWSA) accounting for the remaining 19 %. Over 1948–2016, the mass gain on land from impoundment of water in man-made reservoirs, equivalent to 8 mm SLE, was offset by the mass loss from water abstractions, amounting to 15–21 mm SLE and reflecting a cumulated groundwater depletion of 13–19 mm SLE. Climate-driven LWSA are highly sensitive to precipitation input and correlate with El Niño Southern Oscillation multi-year modulations. Significant uncertainty remains in trends of modelled LWSA, which are highly sensitive to simulation of irrigation water use and man-made reservoirs.
Geospatial Analysis and Simulation of Glacial Lake Outburst Flood
Hazard in Hunza and Shyok Basins of Upper Indus Basin
Authors: Abbas Gilany Syed Naseem , Iqbal Javed , Hussain Ejaz
Published: February 2020

Abstract. The UIB (Upper Indus Basin) is prone to GLOFs (Glacial Lake Outburst Floods). Physical monitoring of such a large area on regular basis is a challenging task especially when the temporal and spatial extent of the hazard is highly variable. The purpose of this study was to map the potentially dangerous glacial lakes and simulate the associated hazard in the downward settlements using HEC-RAS in the GIS environment using Landsat 7 remote sensing data. The study was conducted in Hunza and Shyok sub-basins of UIB where there are several human settlements which are endangered due to the GLOF hazard. Sudden breaches in the unstable moraine dams adjoining receding glaciers may occur because of rapid and huge accumulation of turbulent water in the glacial lakes. The ASTER DEM (Digital Elevation Model) is utilized to detect flow accumulation of glacial hazard involving slope, elevation, and orientation of the mountain glaciers. The study results revealed that settlements of Hunza and Shyok basins are threatened by the GLOFs hazard. Keeping in view the seasonal growth of the potentially dangerous glacial lakes of Hunza basin, a low discharge of 3500 m3/s from potentially dangerous glacial lake can affect 40 %, whereas, a moderate discharge of 5000 m3/s can affect 60% and a high discharge of 7000 m3/s can affect 80 % of the Shimshal village habitat. In Shyok basin, a low discharge of 100 m3/s from both lakes can affect 20 %, whereas, a moderate discharge of 300 m3/s can affect 30 % and a high discharge of 500 m3/s can affect 40 % of the Barah village habitat. The results of the study can provide a platform for the establishment of an early warning and monitoring system to minimize the impact of future GLOFs. Accurate and comprehensive knowledge of potentially dangerous GLOFs is of utmost importance for risk management. A digital repository of GLOFs can enhance the ability to inform policy makers on the vulnerability, risk mitigation and action/adaptation measures.

El Mercado accionario en Honduras
Authors: Romero Pedro
Published: February 2020

El desarrollo del mercado accionario puede llevarse a cabo por fases con la participación de inversionistas institucionales en las primeras etapas y el mercado accionario en la más avanzada. De igual forma, el mercado accionario debe tener ciertas características para ser eficiente, estas son profundidad, liquidez y acceso. Por otro lado, algunos determinantes del mercado accionario son legales, regulatorios, impositivos y macroeconómicos. De esta forma, el trabajo trata de abordar el por qué aún no se ha desarrollado el mercado accionario en Honduras y la problemática actual en el mercado bursátil.

Se concluye que en Honduras no existe un mercado accionario y el actual mercado bursátil es poco desarrollado, esto debido a un mercado bursátil dominado por títulos de deuda pública, inversores institucionales que son demandantes de los títulos públicos y un marco regulatorio prudencial, que prioriza el riesgo por sobre el desarrollo de mercados financieros. A pesar de la existencia de inversores institucionales, se encontró que estos han limitado la creación de un mercado accionario interno principalmente por una fuerte regulación sobre el que, como y cuanto invertir.
Ante un esquema dolarizado para Honduras
Authors: Flores Silva Jorge
Published: February 2020

Solo la economía puede fortalecer la moneda, la dolarización no oficial pero tolerada es un reflejo de la desconfianza que hay en la política cambiaria y monetaria que se ejecuta en el país. La incertidumbre por la devaluación genera desconfianza en la moneda nacional, es aquí cuando empresarios, comerciantes y otros sectores económicos empiezan a cotizar y a dolarizar bienes y servicios. Es por la desconfianza que se sustituye la moneda doméstica por la extranjera, en nuestro caso por el dólar, en la que distintas transacciones financieras que realiza la gente para obtener productos financieros, bienes o servicios tales como compras, alquileres, pago de colegiaturas, depósitos bancarios y otras operaciones se realizan en dólares. Cuando el fenómeno de la dolarización se somete al debate siempre se aborda única y exclusivamente desde la óptica financiera y monetaria, así se rehúye resaltar la visión estructural que hace ver la pérdida de valor de la moneda nacional como efecto de la débil economía. En la medida que se toquen y ataquen los aspectos que dan lugar a un aparato productivo débil y una estructura comercial distorsionada se podrá también fortalecer la moneda doméstica, y al mismo tiempo permitirá comprender más objetivamente la relación existente entre producción y función monetaria.

Authors: Sánchez Aguirre Flor De María , Cóndor Mendoza Verónica , Uribe Hernández Yrene Cecilia , Camones Gonzales Fernando César
Published: February 2020

En la práctica pedagógica el nivel de educación inicial, asume el privilegio de centrar su opción preferencial por los infantes, los cuales son motivados por sus maestras en la formación humana, el presente esbozo de investigación tuvo como finalidad determinar el efecto del programa educativo “protagonizando el cuento” en la internalización de los valores morales infantiles en niños de 5 años. Se entiende que los cuentos definidos por Martin (2006) son agentes motivadores que despiertan la curiosidad en los niños y niñas, donde lo quimérico aparece en lo real, de esta manera el niño asume protagonizar personajes, con fantasía, imaginación, originalidad e involucra promover la resolución de problemas desde su nivel de maduración. Cada cuento recrea la internalización de un valor moral que el sujeto del aprendizaje ira vivenciando y asimilando en la práctica del valor. El tipo de estudio fue aplicado, con un diseño pre experimental, método hipotético deductivo, de tipo censo, contando con 16 infantes, se utilizó la lista de cotejo que mide las dimensiones: disciplina, solidaridad, respeto mutuo y amistad. En la conclusión general se percibe que el p-valor o significancia bilateral (0,000) es menor al nivel de significancia establecido (0,05) rechazándose la hipótesis nula y aceptando la hipótesis alterna, por tanto, el programa educativo “protagonizando el cuento” mejora los valores infantiles en los niños de 5 años de una institución educativa pública.

The Effect of Flipped Classroom Instruction on Developing Saudi EFL Learners’ Comprehension of Conversational Implicatures
Authors: AlSmari Nuha Abdullah
Published: February 2020

While pragmatic instruction has received considerable attention from researchers of interlanguage pragmatics over the last three decades, its effective implementation in the EFL classroom remains an unresolved question. The flipped classroom model is a recently developed teaching method that constitutes a role change for teachers and learners, inverting the front-of-class instruction paradigm in favor of active and collaborative classroom learning. To potentially take advantage of this promising trend, the present study seeks to explore the effectiveness of the flipped classroom for developing Saudi EFL undergraduates’ pragmatic competence and language proficiency by focusing on the comprehension of conversational implicatures during one academic semester. A total of 100 students, assigned to flipped teaching group (n=50) and traditional teaching group (n=50), participated in the study. To elicit the required data, the Oxford Placement Test, a discourse completion test, and reflective e-portfolios were used. A post-test revealed that pragmatic competence significantly increased in the case of the flipped group. The mean score of the flipped group (M=18.48) was considerably higher than that of the traditional group (M=14.68). In following the flipped model of instruction, this progress was influenced by effective out-of-class preparation and appropriate manipulation of in-class time.
Prediction of Standardized Tests and English Competence for Saudi Medical Students’ Performance in an Introductory Physics Course
Authors: Althewini Abdulaziz
Published: February 2020

The following study tested the relationship between admission criteria and college students’ performance in an introductory physics course. For this study, I analyzed the performance of 250 students based on two college admission standardized tests (i.e., General Aptitude Test (GAT), Scholastic Achievement Admission Test (SAAT)), and English competence performance (i.e., average English course grades and reading and communication proficiency test). Based on this analysis, GAT and SAAT, along with English competence, are significant individual predictors for students’ performance in physics. Reading proficiency tests were the best individual predictors in simple linear regression analysis with 19.6% variance. The combined methods, with multivariate regression analysis, explained only 29.3% of physics course grade variance. This low variance of Saudi admission criteria for a single physics course should motivate Saudi policymakers to conduct a national study that includes an increased number of participants. Through such a national study, more evidence-based conclusions regarding the college admission system can be made to improve the admission process for Saudi students.
Teaching Arabic Machine Translation to EFL Student Translators: A Case Study of Omani Translation Undergraduates
Authors: Sabtan Yasser Muhammad Naguib
Published: February 2020

The present paper describes a machine translation (MT) course taught to undergraduate students in the Department of English Language and Literature at Dhofar University in Oman. The course is one of the major requirements for BA in Translation. Fifteen EFL translation students who were in their third year of study were enrolled in the course. The author presents both the theoretical and practical parts of the course. In the theoretical part, the topics covered in the course are outlined. As for the practical part, it focuses on the translation students’ post-editing of online MT output. This is beneficial to the students as free online MT systems can potentially be used as a means for improving student translators’ training and EFL learning. This is achieved through subjecting MT output to analysis or post-editing by the students so that they can focus on the differences between the source and target languages. With this goal in mind, assignments were given to the students to post-edit the Arabic and English MT output of three free online MT systems (Systran, Babylon and Google Translate), discuss the linguistic problems that they spot for each system and choose the one that has the fewest number of errors. The results show that the students, with varying degrees of success, have managed to identify some linguistic errors with the MT output for each MT system and thus produced a better human translation. The paper concludes that there is a need to incorporate MT courses in translation departments in the Arab world, as integrating technology into translation curricula will have great effect on student translators’ training for their future career as professional translators.
Acoustic Study of Tone 3 Sandhi in Beijing and Taiwan Mandarin
Authors: Yin Hui
Published: February 2020

Studies on Mandarin tone sandhi have focused on Beijing Mandarin. Taiwan has been politically separated from mainland China since 1949, but it is not known if tone sandhi in Taiwan Mandarin displays different patterns or characteristics. However, there has been no comparative study to investigate if Beijing Mandarin and Taiwan Mandarin display the same tone sandhi pattern. This study aims to fill this gap by comparing Beijing and Taiwan Mandarin through a productive experiment to examine acoustic differences between sandhied tone 3 and lexical tone 2. The results indicate that tone 3 sandhi among Mandarin dialects is not a homogeneous category, but displays a graded phenomenon of a categorical change and tonal reduction. The experimental evidence shows that acoustic difference between sandhied tone 3 and lexical tone 2 is larger in Beijing Mandarin than that in Taiwan Mandarin. Gender effects are also detected and acoustic difference in female samples is consistently larger than that in male samples across Beijing and Taiwan Mandarin. The findings suggest that the third tone sandhi in Beijing Mandarin is more like a categorical change (i.e., changed to lexical tone 2) whereas the sandhi in Taiwan Mandarin is more like a tonal reduction.
A cor, a arte e a metáfora visual: um relato de experiência de revitalização urbanística
Authors: Tenorio Morgana Andreia Medeiros , Cavalcante Sandra Maria Silva , Machado Edileine
Published: February 2020

O presente artigo inicia-se por reflexões sobre os impactos e a transformação na vida de duas comunidades revitalizadas por intervenções socioculturais promovidas pelo uso de cores, na forma de arte visual, mais especificamente, as cidades de Medellín, na Colômbia, e Santa Catarina de Palopó, na Guatemala.  A partir desse enquadramento geral, o artigo apresenta um relato de experiência do início de um projeto de recuperação de uma região da cidade de Maceió (Alagoas), mais precisamente a comunidade “Vila Redenção”. O projeto, intitulado “Intervenções urbanas no Polígono do CESMAC”, é desenvolvido por estudantes e professores do curso de Arquitetura e Urbanismo do Centro Universitário CESMAC e conta com a participação efetiva da comunidade local e de uma empresa parceira. A iniciativa focaliza o uso de heurísticas nas produções desenvolvidas, estimulando a capacidade criativa e inventiva dos estudantes. Essa capacidade, manifestada em expressões artísticas visuais, essencialmente metafóricas, é compreendida, neste artigo, à luz do conceito de blending, ou integração conceptual (FAUCONNIER & TURNER, 2002). O artigo constitui-se, em síntese, na sistematização do relato de uma experiência, em andamento, que institui-se como o campo de pesquisa para a autora.
Bluesman – Baco Exu Do Blues: pela criação de novas narrativas possíveis para o sujeito negro
Authors: Oliveira Juliane Ferraz
Published: February 2020

Este trabalho parte da compreensão do sujeito negro como aquele que, dentro da sociedade brasileira, se enquadra na parcela da população que se reconhece como preta ou parda. Nesse sentido, ser negro é construir-se e ser construído identitariamente como pertencente a uma parcela da população que fora durante muito tempo marginalizada. Por reconhecer a complexidade de definição do sujeito negro e a importância de ouvir essas vozes que foram durante muito tempo dissidentes, disponho-me a investigar o processo de perspectivação de si, enquanto pessoa negra, na canção Bluesman do rapper Baco Exu do Blues. Mais precisamente, o estudo visa compreender, em uma perspectiva discursivo-cognitiva, esse processo de perspectivação e encenação da experiência do sujeito negro na narrativa construída por Baco Exu do Blues na música Bluesman. Compreendo que a perspectivação cognitiva é uma operação básica constitutiva da capacidade narrativa humana e que essa pode ser flagrada e descrita na dinâmica de encenação enunciativa das narrativas analisadas. Assumo como hipóteses que: i) na base da construção identitária como “pessoa negra” do sujeito em estudo está o processo de perspectivação da experiência de (re)construção de narrativas sobre si; e ii) esse processo implica referenciar-se enquanto negro com base na co-construção de metáforas multimodais. Como forma de atingir o objetivo assumido, utilizarei como referencial teórico Forceville (2016), por sua importância na interpretação de objetos de ordem multimodal; Brandt (2004), que permite a construção de uma análise ancorada na teoria dos níveis de integração; e Lakoff (1980), por compreender sua relevância para qualquer pesquisa que se proponha a estudar o processo de metaforização.
Gender, Performativity, and Agency in Virginia Woolf: A Butlerian Reading of Orlando
Authors: Sadjadi Bakhtiar , Hojabri Sirwe
Published: February 2020

The present paper attempts to closely study Virginia Woolf’s Orlando in terms of Judith
Butler’s concepts of gender, performativity, and agency. Woolf examines women, their
struggles and positions in literary history, and their needs for independence. Themes in her works consist of gender relations, class hierarchy, and the consequences of war. In most of her novels, she moves away from the use of plot and character and, instead, emphasizes the psychological aspects of her characters. In Orlando, the protagonist lives through centuries and Woolf allows her character to transform into a female halfway during the novel. The novel is directly engaged in the women’s position and mentality through the lines, dialogues, and events. The principal question of the present study focuses on the perspectives through which gender is presented and the way it could be observed in relation to Butler’s theory of gender as performance. The current survey is further concerned with the angles through which the novel reflects gender troubles and identity crisis of the women, conventionally defined as a minor category, according to Judith Butler’s poststructuralist approach to the analysis of identity. Consequently, there is a confluence between the development of Woolf’s female characters in the novel and Butler’s critical notion concerning the subject’s attempts to present performativity in the form of an active agent.

Algunes qüestions sobre l'anomenat "problema dels joves i l'habitatge"

Published: February 2020

Les dificultats que els joves tenen actualment per accedir al mercat de l’habitatge

semblen haver arribat a un punt extrem. De fet, l’edat d’emancipació de la població jove s’ha

anat endarrerint successivament en els darrers vint anys, la qual cosa ha repercutit en les

relacions familiars, la demanda d’habitatge, els índexs de natalitat i la construcció dels itineraris

Young people’s difficulties in gaining access to the housing market seem to have reached an extreme point. In fact, the emancipation age has been increasing progressively over the last twenty years, which has had repercussions in family relationships, housing demand, the birth rate and the construction of life paths. To carry out diagnoses and suggest miraculous remedies based upon the average of averages is always a bold and reductionistic resort, especially when dealing with such a heterogeneous group of people integrating multiple casuistries. In spite of all this, the global magnitudes do not offer particularly optimistic indications relating to the insertion of young people within the labour and housing markets.

Emancipación y estrategias residenciales de los jóvenes en Madrid
Authors: Martínez Goytre Elena
Published: February 2020

Los cambios experimentados en el mercado de vivienda durante los últimos años

en Madrid han contribuido a reconsiderar tanto el funcionamiento del propio mercado como las

consecuencias sociales, económicas y políticas que plantea.

El impacto de esos cambios sobre los grupos sociales no es homogéneo, siendo de destacar el

diferente efecto que tiene sobre los grupos de edad. Mientras que los propietarios de una

vivienda contemplan el incremento de valor de su patrimonio inmobiliario, los que viven en

alquiler, y especialmente los que acceden por primera vez al mercado, se encuentran con que

acceder a un bien básico como es la vivienda se convierte en una empresa cada vez más

difícil. Se trata, por tanto, de analizar lo que supone para los jóvenes madrileños el acceso a la

vivienda y los efectos sobre sus proyectos vitales.

The changes experienced in the housing market over the last few years in Madrid have contributed to reconsider the operation of the market, as much as its social, economical and political consequences.

The impact of these changes on social groups is not uniform, especially amongst different age groups. While house owners enjoy an increase in the value of their property, those in the rental sector, and especially those renting for the first time, find that the access to a primary need becomes ever increasingly more difficult. This article seeks to analyse the impact which this situation creates on young people in Madrid and the effects upon their future life path.

Els canvis experimentats en el mercat de l’habitatge durant els últims anys a Madrid han contribuït a reconsiderar tant el funcionament del propi mercat com les conseqüències socials, econòmiques i polítiques que planteja.

L’impacte d’aquests canvis sobre els grups socials no és homogeni, essent destacable el diferent efecte que té sobre els grups d’edat. Mentre que els propietaris d’un habitatge contemplen l’increment de valor del seu patrimoni immobiliari, els que viuen de lloguer, i especialment els que accedeixen per primera vegada al mercat, troben que accedir a un bé bàsic com és l’habitatge es converteix en una empresa cada vegada més difícil. Es tracta, per tant, d’analitzar què suposa pels joves madrilenys l’accés a l’habitatge i els efectes sobre els seus projectes vitals.

Una política de vivienda innovadora: la experiencia de Cataluña
Authors: Clavell Nadal Dolors
Published: February 2020

Las principales víctimas de la llamada crisis de inaccesibilidad a la vivienda que se

sufre en España y Cataluña en los últimos años son las personas jóvenes en edad de

emancipación, las personas mayores que viven de alquiler y no pueden afrontar los

incrementos de renta, las familias monoparentales y los/las inmigrantes. Lo primero que creo

interesante señalar es que son víctimas pero a mi juicio no deben ser revictimizadas con un

discurso asistencial y plañidero. Al contrario, en especial las personas jóvenes deben

convertirse en agentes activos en la lucha contra una situación que les perjudica, y por ello

estas notas tienen como objetivo mostrar algunas claves para construir un discurso alternativo

que permita un efectivo cambio en la política de vivienda tradicionalmente aplicada en nuestro

país.

The principal victims of the so-called crisis of accessibility to housing that Spain and Catalonia have been undergoing in recent years are young people in the emancipation age range, elderly people in rental housing unable to meet the increase in rents, and single-parent and immigrant families. The first aspect which should be emphasised is that while they are victims, they should not be re-victimised using a welfare and plaintive discourse. On the contrary, young people especially need to become active agents in the fight against a situation which causes them harm. For this reason the article seeks to highlight some key points, in order to build an alternative discourse allowing for an effective change in the housing policy traditionally applied in Catalonia.

Les principals víctimes de l’anomenada crisi d’inaccessibilitat a l’habitatge que es pateix a Espanya i Catalunya els darrers anys són les persones joves en edat d’emancipació, les persones grans que viuen de lloguer i no poden fer front als increments de renda, les famílies monoparentals i els/les immigrants. El primer que crec interessant assenyalar és que són víctimes però al meu judici no han de ser revictimizades amb un discurs assistencial i planyent. Al contrari, en especial les persones joves han de convertir-se en agents actius en la lluita contra una situació que els perjudica, i per això aquestes notes tenen com a objectiu mostrar algunes claus per construir un discurs alternatiu que permeti un efectiu canvi en la política d’habitatge tradicionalment aplicada al nostre país.
El impacto de la inmigración extranjera en la estructura demográfica de las ciudades. El caso de la ciudad de Barcelona y su región metropolitana
Authors: Bayona Jordi
Published: February 2020

La última década, caracterizada por la aceleración de la llegada de inmigrantes

internacionales, ha significado para la mayoría de ciudades españolas un brusco cambio de

tendencia en la evolución de su población, recuperando residentes después de un intervalo de

decrecimiento y desconcentración. El objetivo de este texto es analizar los cambios acaecidos

en la ciudad de Barcelona, centrando la atención en la estructura demográfica de su población,

en los principales fenómenos demográficos y en la movilidad de la población a escala

metropolitana, para concluir observando el efecto de estos cambios a nivel inframunicipal y, en

especial, sobre la distribución de la población de nacionalidad extranjera en la ciudad.

L’última dècada, caracteritzada per l’acceleració de l’arribada d’immigrants internacionals, ha significat per la majoria de ciutats espanyoles un brusc canvi de tendència en l’evolució de la seva població, recuperant residents després d’un interval de decreixement i desconcentració. L’objectiu d’aquest text és analitzar els canvis succeïts a la ciutat de Barcelona, centrant l’atenció en l’estructura demogràfica de la seva població, en els principals fenòmens demogràfics i en la mobilitat de la població a escala metropolitana, per concloure observant l’efecte d’aquests canvis a nivell inframunicipal i, en especial, sobre la distribució de la població de nacionalitat estrangera a la ciutat

The last decade has been dominated by the acceleration of international immigration flows; this

process has produced, in the majority of Spanish cities, an important change in the

demographic evolution of their population, recovering in this way residents after a period of

decreasing and deconcentration. The aim of this paper is to analyze the main changes on the

demographic structure of Metropolitan Barcelona, with special emphasis on the demographic

phenomena and mobility. The paper ends analyzing these processes at infra-municipal level for

the residents with foreigner nationality.
Situationism and the Virtues of Business
Authors: Spino Joseph ,   Philosophy Documentation Center
Published: February 2020

Many ethicists endorse a character-based approach to business ethics (CBE). This approach includes a focus on the development of particular traits of character amenable to virtuous business practices. Situationists claim, however, that traditional understandings of character are challenged by various findings in empirical psychology. While defenders of CBE have responded this claim, these responses are very similar to those made in defense of a more general virtue ethical theory against situationist arguments. I argue that whatever promise such responses to situationism have in defending a general virtue ethical theory, they are not up to the task of defending CBE. As a result, CBE is in need of novel responses to situationism or significant revision.
The Pragmatist’s Call to Democratic Activism in Higher Education
Authors: Weber Eric Thomas ,   Philosophy Documentation Center
Published: February 2020

This essay defends the Pragmatist’s call to activism in higher education, understanding it as a necessary development of good democratic inquiry. Some criticisms of activism have merit, but I distinguish crass or uncritical activism from judicious activism. I then argue that judicious activism in higher education and in philosophy is not only defensible, but both called for implicitly in the task of democratic education as well as an aspect of what John Dewey has articulated as the supreme intellectual obligation, namely to ensure that inquiry is put to use for the benefit of life.
Correlating the Relationship Between U.S. News & World Report Rankings and Social Media Efficiency of the Top 10 Ranked Private Universities at the State Level (Massachusetts), the United States and the World (U.S. News & World Report, 2019)
Authors: Goncalves Patrick R.
Published: February 2020

This analysis will provide an overview of the top 10 ranked (U.S. News 2019) universities at the state level (Massachusetts), U.S. national, and the world. For each of the universities being analyzed in this study, data will be collected from university-centralized social media accounts. The following types of social media channels will be represented: Facebook, Twitter and Instagram. This study will report on the gross number of followers for each of these channels along with total institutional operating expense. The rationale is to establish a baseline for return on investment (ROI) pertaining to social media efficiency/influence by drawing correlations to current (2019) university rankings by U.S. News & World Report. For the state level assessment, Massachusetts was selected simply based upon the proximity to where the study was being conducted, Boston College.
Los cimerios homéricos (Od. XI 11-19) y su presencia en la literatura grecolatina
Authors: Linares Sánchez Jorge J.
Published: February 2020

En el canto XI de la Odisea se incluye por primera vez una descripción del pueblo de los cimerios en el marco del relato de un viaje al mundo de los muertos. En este artículo realizamos un análisis comparativo del pasaje homérico y de diversos textos de la literatura grecolatina a fin de mostrar cómo, a partir de Homero, los cimerios se convirtieron en un elemento tradicional del tema. Para ello, explicamos las semejanzas y diferencias en cuanto a la presencia, denominación, características y ubicación de este pueblo mítico en cada texto con respecto al modelo homérico.

In canto Odyssey XI a description of the Cimmerian people is included for the first time as part of a journey to the netherworld’s narrative. In this paper a comparative analysis of the Homeric passage and of various texts from Greek and Latin literature is carried out in order to show how, since Homer, the Cimmerians became a traditional motive of this theme. For that purpose, the similarities and differences produced in terms of the presence, name, characteristics and location of this mythical town have been explained in each text regarding the Homeric model.
Relato (διήγημα) y écfrasis (ἔκφρασις) en la novela griega
Authors: Fernández Garrido Regla
Published: February 2020

En las cinco novelas griegas conservadas completas se amplifican con frecuencia algunos de los elementos que constituyen los relatos en ellas contenidos (persona, hecho, circunstancia, lugar y modo) hasta constituir écfrasis retóricas como se describen en los Progymnasmata. Se analizan aquí dichas écfrasis, su función y sus rasgos formales y de estilo.

In the five extant Greek novels some of the elements of narrative (person, event, time, place and manner) are often amplified in order to become rhetorical ekphraseis as described in the Progymnasmata. In this paper these ekphraseis, their function and their formal and stylistic characteristics are analysed.
Fedro e Aviano presenze ‘fantasma’ nella Spagna medievale
Authors: Mordeglia Caterina
Published: February 2020

L’analisi della diffusione manoscritta delle favole di Fedro e Aviano e dei loro rifacimenti mediolatini nella Spagna medievale rivela una pressoché totale assenza di testimonianze che contrasta con il resto d’Europa. Si registrano solo timidi tentativi di penetrazione del genere attraverso i contatti culturali con il Sud della Francia, di cui l’esempio più significativo è offerto da due favole contenute nel ms. Madrid, RHA, 39 (s. XI), qui riportate con testo critico rivisto e la prima traduzione italiana. Tuttavia una presenza ‘sommersa’ del genere, precedente alla diffusione delle prime edizioni a stampa – anch’esse ricollegabili ad ambienti culturali italiani e nord-europei – è comprovata dalle reminiscenze favolistiche classiche nella Disciplina clericalis di Pietro Alfonsi (s. XII) e nel Libro de los gatos (s. XIV), versificazione in castigliano delle Fabulae di Oddone di Cheriton.

The analysis of the manuscripts’ spread of Phaedrus and Avianus’ fables and their Latin rewritings in Spain during the Middle Ages reveals an almost total absence of witnesses, contrary to the rest of Europe. There are only shy  attempts of penetration of the genre through the cultural contacts with Southern France. The main example is offered by two fables transmitted by the ms. Madrid, RAH, 39 (s. XI), here presented in a new critical edition with the first Italian translation. Anyway a ‘ghost’ presence of the Latin fables before their first printed editions – also due to the Italian and North-European cultural contacts – is confirmed by their tracks in the Petrus Alfonsi’s Disciplina clericalis (XIIth century) and the Libros de los gatos, a rhytmical translation in Castilian language of Odo of Cheriton’s Latin fables (XIVth century).
EVALUATION OF THE USE OF BOF SLAGS FOR PREPARING SURFACE BY BLASTING
Authors: DIAZ PILOÑETA MARINA , ORTEGA FERNANDEZ FRANCISCO , MESA FERNÁNDEZ JOSÉ MANUEL , MORAN PALACIOS HENAR
Published: February 2020

ABSTRACT:
Approximately 400 million tons of steel slags are generated annually worldwide. For each ton of steel, between 130 and 100 kg of slags are produced depending on the process and the composition. Although efforts have been made to recycle this slag, a significant part still ends up in the landfill, Therefore, it is necessary to look for new alternatives of use. One of the possibilities is its use in the surface preparation of building materials surfaces. Blasting has many applications in different industries, but the associated environmental problems imply a low number of research works developed in this field. Although BF (Blast furnace) slag is regulated by the standard UNE-EN ISO 8504-2:2002, BOF (Basic Oxygen Furnace) slag is not. The aim of this paper is to analyze the possible application of these wastes as a substitute for traditional abrasives. The results show that it is possible to use BOF slag both for surface cleaning. However, a more in-depth investigation is needed.

Key Words: circular economy; slags; civil engineering; abrasive blasting.
