"Efecto invasión". Populismo e ideología en el discurso político español sobre los refugiados. El caso de Vox
Authors: Sosinski Marcin , Sánchez García Francisco José
Published: January 2025

El presente trabajo se centra en el análisis de los rasgos lingüísticos del discurso de Vox, partido ultraderechista que ha desembarcado en la escena política española revitalizando la polarización ideológica del eje izquierda-derecha (tras décadas de homogeneización “bipartidista”), de la que resulta un lenguaje político fuertemente ideologizado. Es sabido que los líderes populistas se sirven de ciertos conceptos metafóricos para “enmarcar” eficazmente, es decir, de manera persuasiva. Aquí pondremos el foco en los frames que conceptualizan la inmigración como un problema, especialmente relevantes en las intervenciones de Vox. El corpus de estudio está compuesto por una selección de entradas en la red social Twitter de los principales líderes de la formación política ultraderechista, para analizar pormenorizadamente los marcos conceptuales (Lakoff, 2007) que predominan en dichos tuits, así como el índice de las palabras más frecuentes. Para ello, nos centraremos específicamente en las reacciones de los líderes de Vox a la toma de Kabul por el régimen talibán y la posterior llegada de refugiados afganos a España. Los resultados obtenidos evidencian que los marcos de Twitter a propósito de los migrantes llegados a nuestro país retroalimentan el argumentario del partido difundido a través de los medios de comunicación y reproducen los estereotipos del discurso de odio, característico de los partidos populistas de ultraderecha.
Reconfiguración del discurso sobre refugio en el contexto sudamericano: integración y autosuficiencia como solución duradera
Authors: Gil Araujo Sandra , Clavijo Padilla Janneth
Published: January 2025

Este artículo indaga los modos en que el refugio es pensado y problematizado en el actual contexto sudamericano, así como las políticas e instrumentos propuestos para su intervención. Nuestro análisis se enmarca en los estudios críticos del refugio, y desde la perspectiva de la gubernamentalidad apunta a colaborar en el rastreo de los contenidos discursivos de las racionalidades políticas y tecnologías de gobierno a través de las cuales las poblaciones en necesidad de protección internacional son gobernadas en el marco del neoliberalismo o liberalismo avanzado En particular, examinamos cómo ACNUR, con la colaboración de otros actores, operacionaliza su mandato de protección vinculando la solución duradera de permanencia con el paradigma de la integración y la activación de las poblaciones refugiadas como sujetos autosuficientes, autónomos, participativos y responsables de su propio destino. Esta indagación se sustenta en una metodología cualitativa basada en el análisis de un corpus documental cuya recopilación contempló materiales producidos por diversos actores, y espacios interinstitucionales, involucrados en el tratamiento político de la cuestión del refugio. Concluimos que el gobierno del refugio es una de las formas concretas que ha adquirido el gobierno de lo social en la gubernamentalidad globalizada.

Los candidatos de la crisis. Ethos y legitimidad en las elecciones presidenciales argentinas de 2003
Authors: Cané Mariana
Published: January 2025

Los discursos de los candidatos a la presidencia argentina en el año 2003 constituyeron un mojón clave en el proceso de redefinición de la legitimidad de la política que se desarrolló luego de los episodios de diciembre de 2001. La disputa por esa definición marcó las elecciones presidenciales del 2003, que se realizaron en un contexto de signado por la desconfianza ciudadana respecto de “los políticos” y por la fragmentación del mapa político-partidario. El objetivo de este trabajo es dar cuenta de los modos en los cuales los principales candidatos se posicionaron en tanto actores de la política en un contexto de cuestionamiento de la legitimidad de la política misma y, por tanto, de su representatividad como tales. Para ello, se analiza un corpus conformado por discursos públicos y spots de campaña de los y las candidatas que más votos obtuvieron (Carlos Menem, Néstor Kirchner, Ricardo López Murphy, Adolfo Rodríguez Saá y Elisa Carrió) desde una perspectiva ethica, es decir, centrada en los ethos discursivos proyectados por cada candidato. Una de las principales hipótesis de trabajo ha sido que en y por esos ethè los candidatos no sólo construyeron una imagen de sí con vistas a alcanzar la presidencia, sino que también se resignificó la política como conjunto de discursos, prácticas, actores, instituciones en los que se disputa y define lo común de la comunidad. Los disímiles modos de presentación de sí de cada candidato -en tanto actores de la política- contribuyeron a redefinir los límites de esa misma superficie de inscripción en la que emergieron.
Estrategias de polarización en el discurso político de Unidos Podemos: el estado español y los conservadores como alteridad antidemocrática
Authors: González Gómez Carmen
Published: January 2025

Este trabajo aborda el discurso parlamentario de Unidos Podemos durante la XII legislatura (2016-2019) en relación con el conflicto catalán. La postura de la formación respecto a la crisis territorial ha sido tildada en ocasiones de “equidistante” por oponerse al proceso independentista y por rechazar al mismo tiempo la aplicación del artículo 155 de la Constitución en Cataluña. No obstante, las estrategias difundidas por el partido en el Congreso de los Diputados han dejado entrever una tendencia a la polarización discursiva. Muchas de ellas han ido encaminadas a reforzar la idea de una alteridad antidemocrática identificada con el estado español que respondía de manera represiva a las demandas del pueblo catalán. Este estudio pretende identificar en qué consisten estas estrategias y cómo repercuten en la selección léxica de su discurso.
La construcción del personaje mediático: Donald Trump en el discurso periodístico
Authors: Vellón Lahoz Francisco Javier
Published: January 2025

El artículo estudia las estrategias discursivas para la creación del personaje mediático en el relato informativo periodístico. Para ello se centra en los mecanismos lingüísticos y textuales a partir de un corpus formado por 45 crónicas de El País y de ABC, comprendidas entre agosto y octubre de 2020, en plena campaña electoral por la presidencia de Estados Unidos, y protagonizadas por Donald Trump. El análisis demuestra que existen recursos de índole narrativa que contribuyen a la caracterización del personaje: enunciados que determinan el modelo de agentividad del sujeto; la selección léxica; las voces del discurso a través del estilo directo; construcciones de contraste, contraargumentativas e incisos valorativos. Por otra parte, la comparación entre los artículos de los medios citados revela que, más allá de las coincidencias, el factor ideológico y el relacionado con el estilo comunicativo son relevantes en relación al tipo de personaje configurado.
La construcción de la evidencia en el reporte de violación a los derechos humanos: el rol de la modalidad
Authors: Castro Claudia
Published: January 2025

El objetivo de este artículo es explorar el rol de la modalidad en el reporte de la violación a los derechos humanos durante la dictadura de Pinochet en Chile (1973-1990), tal como es presentado en el Informe Rettig (1991). En particular, se aborda la forma en que los autores recurren a recursos modales para presentar la evidencia que sustenta su investigación y sus resultados. Desde la perspectiva teórico-metodológica de la Lingüística Sistémico-funcional, la modalidad se estudia considerando el tipo (modalización y modulación), la orientación (objetiva o subjetiva) y la forma de realización (congruente o metafórica). El análisis considera también los posicionamientos interpersonales y las valoraciones presentadas en el texto, de acuerdo con el sistema de la VALORACIÓN. Los resultados muestran que los significados de modalidad juegan un rol fundamental en la presentación y validación de los resultados por parte de la Comisión, en conjunto con la utilización de fuentes externas y el relato de antecedentes y circunstancias que participan en los eventos reportados. Estos recursos operan en el marco del complejo contexto de publicación del informe, en tanto primer documento oficial concerniente a la violación sistemática de derechos humanos en Chile.
Análisis comparado del discurso político outsider en Marruecos: el boicot a las elecciones legislativas de 2016
Authors: Macías Amoretti Juan A.
Published: January 2025

Desde la teoría de la sociología del poder y utilizando el marco teórico-metodológico del análisis ideológico del discurso propuesto por Teun van Dijk, el presente artículo relaciona los conceptos de discurso y sociedad en la representación narrativa de un hecho político trascendente como unas elecciones legislativas. Para ello, se analiza el discurso político emitido por dos organizaciones políticas y sociales de Marruecos que conforman opciones contestatarias al régimen político e institucional vigente: al-‘Adl wa-l-Iḥsān (Justicia y Espiritualidad), desde el islam político, y al-Nahŷ al-Dīmuqrāṭī (La Vía Democrática), desde la izquierda marxista revolucionaria. Ambas formaciones, concebidas como movimientos sociales y políticos, reaccionaron planteando un boicot a las elecciones legislativas de octubre de 2016 por razones diferentes, pero relacionadas con su respectiva posición en la competición política y con su respaldo social. El interés de este análisis se basa en una concepción moral de la acción política democrática, que supone, por una parte, la utilización de la ideología como recurso de poder y, por otra, la utilización de conceptos ideológicos que son especialmente relevantes en la representación simbólica del “otro” en relación con la construcción de la identidad social y política “democrática” y el cambio social.
¿Es correcto decir toque de queda, nueva normalidad o confinamiento? Recursos valorativos sobre el léxico de la pandemia en las Columnas sobre la lengua (CSL)
Authors: Melero Carnero Laura
Published: January 2025

Con la llegada de la pandemia a nivel global, la población no sólo ha sido testigo de la crisis económica y social, sino que también lo han sido de la incorporación de términos relacionados con este fenómeno sanitario, que han pasado a formar parte de su lenguaje cotidiano. En este último aspecto, el lingüístico, las “columnas sobre la lengua” se han encargado de mostrar a sus lectores estas novedades y si estas nuevas palabras son viables en la lengua española. En el marco teórico de la Teoría de la Valoración, el presente trabajo analiza los recursos valorativos utilizados por los columnistas para evaluar estos neologismos pandémicos. Se ha creado un corpus que incluyen aquellas columnas sobre el COVID-19 y los columnistas que han tratado esa cuestión. Los resultados han permitido revelar varios aspectos lingüísticos: 1) la presencia de las normas establecidas por la Real Academia Española cuando se evalúan estos neologismos, 2) la constante evolución de la lengua española y 3) un cierto grado de purismo lingüístico con la llegada de neologismos al español.
Representación de la pandemia en titulares de prensa. Análisis multimodal de El Espectador y El Tiempo
Authors: Prada Penagos Rodolfo , Ladino Marín Paola Consuelo , Adán Díaz Óscar Eduardo
Published: January 2025

Este artículo presenta los resultados de un análisis de discurso multimodal aplicado a titulares de los diarios colombianos El Tiempo y El Espectador para identificar la representación que construyeron de la pandemia. El estudio se basó en las propuestas teórico-metodológicas para el análisis de artefactos multimodales formuladas a partir de la Lingüística Sistémica Funcional. Aunque los procesos intersemióticos no son similares en los diarios analizados, en ambos la fotografía es portadora de gran parte del significado y aumenta las posibilidades interpretativas, especialmente en relación con estructuras léxico-gramaticales exofóricas. Los textos tienden a presentar los eventos (hacinamiento, pobreza, desarraigo, riesgo de contagio), en tanto que las imágenes a los participantes (poblaciones vulnerables), borrando al Estado como agente de las acciones.
Arriba y adelante: La metáfora del movimiento en los lemas de campaña y gobierno presidencial en México de 1934 a 2018
Authors: Salgado López Melanie , Gómez Gordillo Luis Ángel
Published: January 2025

El objetivo de este trabajo es analizar los lemas o eslóganes de campaña y de gobierno de los candidatos presidenciales que ganaron la elección en México (desde el gobierno de Lázaro Cárdenas 1934-1940 hasta el de Andrés Manuel López Obrador 2018-2024), todo a la luz de la configuración metafórica que se hace de la contienda electoral y del periodo de gobierno presidencial como un movimiento. Para ello, retomamos el marco de las metáforas abordado por Lakoff y Johnson (1980) y utilizamos conceptos del aspecto léxico verbal (Talmy, 1985; Van Valin y Randy, 1997) que nos permitan vincular el empaquetamiento sintáctico de las expresiones para relacionarlas con su forma metafórica. Así pues, comenzamos explicando la metáfora como un proceso mental de comprensión de la realidad y algunos elementos básicos con respecto a los verbos de movimiento y las locuciones que codifican dirección en el español. En seguida abordamos la metodología de la constitución del corpus y del análisis que se aplicó para esta investigación. Finalmente se ofrecen los resultados del estudio acompañados de una discusión con la cual se pretende aportar una reflexión sobre las prácticas comunicativas de los presidentes mexicanos durante la campaña y cómo estas cambian una vez que se ha ganado la presidencia.
Uneven Impact of Covid-19 on Sex Workers in Spain
Authors: Meneses-Falcón Carmen , Rúa-Vieites Antonio , García-Vázquez Olaya
Published: January 2025

The coronavirus pandemic has had major impacts on sex workers, with notable differences in bargaining power, coercion, and health. Therefore, the aim of this research is to describe the different impacts of the Covid-19 pandemic on paid sex workers. For this purpose, we conducted a comparative analysis using questionnaires collected from 605 individuals representing two segments of sex industry: one socio-economically lower (415) and the other middle-income (190). In both cases, a sociological questionnaire was used. In S1, it was conducted in person with intentional sampling, while in S2, it was conducted online using social media. Regarding the results, there were significant differences between the two groups, with the lower segment being more vulnerable and facing worse conditions: more difficulties with their documents, lower level of education, less support network, more clients, more insecurity in the place where they work (streets, industrial estates or roads), younger age of starting prostitution, more coercion or need to start (most reported reasons to start in prostitution were economic need, lack of documentation, family responsibilities and debts), less possibilities of health insurance, worse physical and mental health, more food insecurity, and lower income. The middle sector showed: more autonomy, was less impacted by the Covid-19 pandemic, had been in Spain for longer, often holding a residence permit, having more protection measures, having a higher level of education, having a greater support network, having started prostitution at an older age, and were less likely to have been coerced into it. In conclusion, it is important not to homogenise all people in sex work, as there are different sectors and needs within the sex market in Spain, which require different or more targeted policies and interventions.
Rítuselméletek az európai őskor írással nem rendelkező társadalmai vallásának vizsgálatakor
Authors: Hegedüs Gabriella
Published: January 2025

Az elmúlt két évtized egyik legdinamikusabb és legtöbb vitát kiváltó régészeti diskurzusa a rítust helyezi kutatásai középpontjába. Ennek ellenére az európai ősrégészet mind a mai napig nem rendelkezik megfelelő elméleti keretrendszerrel a korszak rituális gyakorlatainak azonosítására, elemzésére és értelmezésére. Így – meghatározások hiányában – a rítusok azonosításának és értelmezésének nehézségei a kortárs archeológia egyik legnagyobb problémáivá váltak. Dolgozatomban a rituálé fogalmával összefüggésbe hozható definíciós és egyéb problémák, a különböző rítuselméletek, valamint a régészeti esettanulmányok alapján igyekszem igazolni ezt a feltevésemet. Amennyiben sikerül igazolnom, miért éppen azok a vallásra, illetve a rítusra vonatkozó teóriák kerültek előtérbe, amelyek napjaink vizsgálatait túlnyomórészt meghatározzák, megnyílik az út, hogy felvázoljam és elemezzem azt a két irányvonalat, melyek meghatározónak tartok a kortárs elméleti kutatások között. Régészeti esettanulmányok mutatják be a kognitív kutatási irányzat, valamint a gyakorlat elméletet felhasználó vizsgálatok előnyeit és problémáit. Ezáltal lehetőségem nyílik, hogy felvázoljam, a rítusrégészet jelenlegi trendjei milyen interpretációs előnyökkel és hátrányokkal járnak a vallás, valamint a rituálé kifejezések aspektusából. Véleményem szerint megalapozottan tudok érvelni amellett, hogy a kortárs európai ősrégészet rítusokkal kapcsolatos kutatásai fordulóponthoz érkeztek, melynek következtében az archeológiai elemzések egy részéből vagy eltűnik a vallás az őskori társadalmak életéből vagy a rituálék felfogásának egyik elméleti vonulatát ki kell vonnunk a vallásrégészet témaköréből.
Anarchia és rend

Dolgozatomban az esztétikát normatív, előíró gyakorlatként, a művészet szabályrendszereinek kétségkívül elfogult, de racionális argumentációt alkalmazó megalkotójaként ábrázolom. Ennek segítségével vagyok képes arra magyarázatot adni, hogy művészet és szabadság összefonódása hogyan lehet úgy az esztétikai tapasztalat lehetséges formája, hogy közben azt nem ontológiai vagy pszichológiai tények, hanem egy történetileg kialakult beszédmód alkotta meg. E narratíva megszületését az ízlés korai filozófiája és a felvilágosodás emancipációfelfogásának találkozásával magyarázom, majd bemutatom reneszánszát a XX. századi nyugati marxista esztétikák elemzése során. Végül amellett érvelek, hogy a hagyományos esztétika gyakorlatai jelentős kritikai potenciával bírhatnak ma is, ám nem a kultúra építőiként, hanem a kulturális-politikai valóság megszakítóiként, ami ezt a megszakítást leginkább saját céljaira, nem pedig kézzelfogható politikai-kulturális programok megvalósítására képes használni.

The Effect of Tip Clearance Kaplan Ducted Propeller in Offshore Supply Vessel (OSV) on Hydrodynamics
Authors: Winarno Arif , Sakti Gedhe Angkoso Nur Sofa , Sugianto Erik
Published: January 2025

A ducted propeller is a modification of a propeller by adding a duct or nozzle. The purpose of using a ducted propeller is to increase thrust, increase propeller efficiency, and encourage better ship movement. This is suitable for Offshore Supply Vessel (OSV) vessels operating on offshore platforms to support oil drilling activities. In designing a kort nozzle, one of the most important components is the tip clearance, the distance between the edge of the propeller and the inner nozzle. The diameter of the kort nozzle can affect the thrust efficiency of the propeller. Due to the blade momentum theory for ducted propellers, the volume of water passing through the propeller should be as large as possible, with the smallest possible flow velocity. In this study, numerical simulations using the Computational Fluid Dynamics (CFD) method were carried out to determine the effect of tip clearance on thrust and torque on a ducted propeller with a MARIN foil 19A nozzle type and tip clearance of 10 mm, 20 mm, and 30 mm. From all models, the highest thrust and torque values were obtained from the nozzle 19A tip clearance 10 mm model with thrust 367,413 kN and torque 315,338 kNm. The relationship between tip clearance and thrust is inversely proportional; the greater the tip clearance, the smaller the value of thrust, and the same is true with torque.
Assessment of Aerodynamic Performance of Darrieus H-Rotor Wind Turbine Using Realizable k–ε Turbulence Model Approach
Authors: Ariefianto Rizki Mendung , Fridayana Elyas Nur , Wardhana Wisnu
Published: January 2025

Wind energy extraction gains more attractiveness as the development of renewable energy progresses and the reduction of fossil fuel usage becomes imperative. Consequently, numerous efforts have been made to enhance turbine performance, such as with the Darrieus H-Rotor type, through numerical studies. Computational Fluid Dynamics (CFD) has become a prevalent tool for these studies, utilizing various approaches, including the eddy viscosity model based on the Boussinesq hypothesis, which underpins turbulence models. This research evaluates the performance of the Darrieus H-Rotor Wind Turbine via 2D CFD modeling using the Realizable k–ε turbulence model. The study also considers simulations with the Double Multiple Streamtube (DMST) model and other turbulence models applied to similar turbine geometries, with experimental data serving as validation benchmarks. Approximately 140,000 cells were utilized in the meshing process to balance simulation duration and the accuracy of the Cp value. The results indicate that the Realizable k–ε turbulence model performs satisfactorily, particularly in producing accurate Cp values in the pre-stall region. The comparison of average Cp values against experimental data across eight tip speed ratio points further supports the effectiveness of the Realizable k–ε turbulence model in simulating the aerodynamic performance of the Darrieus H-Rotor Wind Turbine. Nonetheless, the Realizable k–ε turbulence model fails to enable the Darrieus H-Rotor Wind Turbine to achieve positive Cm values across the entire azimuthal angle at lower tip speed ratios, thus not reaching effective self-starting conditions.
The Effect of Capital Types and Social Networks on the Labor Force Participation Process of Syrian Migrants: The Case of Istanbul
Authors: Karabulut Nail Gökhan
Published: January 2025

This research examines the impact of social and human capital on the labor market participation and mobility of the Syrian migrants in the case of Istanbul. Immigrants are participated in the labor market as a part of active or reserve labor force for reasons such as survival, desperation and urgency in the migrated country. In this process, they give a new topic added to the existing employment problems of the city where they live. In this study, employment mobility of Syrian immigrants in the labor market as a heterogeneous group is discussed by making use of the capital concepts defined by Bourdieu sociology and the theory of social network. The effectiveness of the use, reproduction and transition of social and human capital in labor market and mobility (occupational) has been questioned. In Istanbul, as a study case area, academic interest in examining the situation of the Syrian labor force in the labor market in terms of a specific sector and/or the perception of the domestic labor force has increased recent years. However, there is lack of academic studies which focus on the social and human capital of Syrian immigrants which is more unknown and more interesting area and examines the process in the labor market. The aim of the study is to contribute to this gap in the literature. 35 interviews were conducted within the scope of the research, which was handled with an exploratory, qualitative method based on in-depth interviews. The findings revealed that the role of social networks as a component of social capital is effective for labor participation. It has been observed that the use of existing social ties and the involvement in new social networks provide an advantage in accessing to job. Although there is a positive correlation between spatial location and job finding, it has been determined that access to first job is concentrated in regions where labor is cheap and insecure. A differentiation has been observed in vocational mobility appropriate to its qualifications according to human capital components such as language skills, experience and education.
On the syntax of light-headed noun phrases in the Old Irish glosses: dealing with missing data in corpus linguistics
Authors: Garcia Castillero Carlos
Published: January 2025

The Old Irish glosses in contemporary manuscripts are the most reliable evidence for Old Irish syntax. These glosses convey discontinuous utterances that depend on the Latin text to which they are attached. One of the most obvious consequences of this discontinuous and textually dependent character is that the glosses very often convey what we could consider incomplete utterances, i.e. linguistic units that do not have the status of an independent clause or sentence.When it comes to the study of NPs and their syntax, we face cases in which a gloss consists only of a bare NP. This paper deals with these isolated NPs, in particular, with those that are introduced by the light heads intí, aní and a N, and defends the idea that these NPs constitute utterances that may be considered as complete, as against the initial impression, and therefore, that they may be considered for an inquiry on the syntax of Old Irish NPs.This paper covers the following points: a basic quantitative description of the distribution of isolated light-headed NPs and the introduction of the notion of ‘missing data’ (cf. Osborne 2013: 128‒129); a discussion of the notion of ‘free NPs’, i.e. apparently incomplete but meaningful linguistic units; an overview of the linguistic features of isolated NPs, in particular animacy, which is a statistically significant factor explaining the difference between isolated/dislocated light-headed NPs, which are more often animate, and intraclausal light-headed NPs, which are more often neuter; an outline of a wider investigation of all OIr. NPs in order to check if the above-mentioned statistical skew is in fact more general, i.e. that animate NPs are more likely in general to appear as free NPs.

Assessing the Outcomes of Digital Soil Science Curricula for Agricultural Undergraduates in the Global South
Authors: Rico Heidy , de la Puente Mario , de Oro Carlos , Navarro Daniela , Lambis Juan , Londoño Guillermo
Published: January 2025

This academic inquiry examines the efficacy of virtual reality (VR)-based pedagogy for higher learning, specifically analyzing immersive digital instruction for rural agriculture undergraduates studying soil science in Colombia. The investigation tests two hypotheses: first, simulated learning situations improve academic achievement and student investment compared to conventional in-person lectures; and second, modern modalities cultivate affirmative perspectives of the material. Employing a meticulous investigative blueprint across three Colombian university campuses situated in pastoral communities, the assessment involved 89 volunteers separated into experimental and control groups over 14 weeks analyzing soil nutrient administration. Scholastic aptitude, student absorption, and viewpoint appraisals were conducted before and after the module. Statistical calculations including independent sample examinations, variance examinations, effect magnitude, and association analyses were utilized to validate the hypotheses. The results endorse both hypotheses, evidencing augmented academic performance, student engagement, and affirmative attitudes toward soil science among participants experiencing VR-based coursework. This inspection lends valuable discernment into advanced technology’s potential to address rural student challenges, elevating educational outcomes and furthering constructive pedagogical encounters in the developing world.
Teaching Work and Inequality in Argentina: Heterogeneity and Dynamism in Educational Research
Authors: Vassiliades Alejandro
Published: January 2025

The issue of the multiple links between teachers’ work, schooling processes, and social inequalities has been one of the greatest concerns in the field of educational research in Argentina in recent decades. The way in which the task of teaching and the problem of inequality are related and configured has integrated the agendas of the different traditions and areas of knowledge with which the field of pedagogy has established articulations. This article aims to carry out a critical and systematic analysis of scientific production on the links between teaching work, schooling, and inequality in the period 1985–2024. That approach identifies the main conceptual and theoretical–methodological debates, reconstructing three cores of meaning: the way inequality has been signified, the forms of interpreting the multiple links between schooling and teaching in contexts of impoverishment, and the relationships between educational institutions and the environment that surrounds them.
RAFT-mediated polymerization-induced self-assembly of poly(ionic liquid) block copolymers in a green solvent
Authors: Yang Yongqi , Ren Zekai , Li Xiawei , Zhao Enhao , Luo Xin , Yan Youjun , Gao Hongyan , Feng Lijuan
Published: January 2025

Here, we report a novel method for regulating the morphology of block copolymer assemblies through the use of reversible addition–fragmentation chain transfer dispersion polymerization in ethanol. In this method, poly(N,N-dimethylacrylamide) is used as a macromolecular chain transfer agent, and the side chain length of the ionic liquid monomer is modified. A notable change in the morphology of the alkyl-imidazole monomer (1-alkyl-3-(4-vinylbenzyl) imidazolium tetrafluoroborate) was observed when the side chain length was modified from methyl to butyl. This phenomenon can be attributed to a structural change in the alkyl imidazole monomers, which resulted in enhanced solvent-phobic properties. The polymerization kinetics and glass transition temperatures of the block polymers were investigated. These results demonstrated that the polymerization rate increased with increasing number of side chains, whereas the glass transition temperature of the block polymers decreased. It provides a novel approach for the synthesis and utilization of poly(ionic liquid) block polymers with higher-order morphologies.
On the kernel of actions on asymptotic cones
Authors: Baik Hyungryul , Jang Wonyong
Published: January 2025

Any finitely generated group 𝐺 acts on its asymptotic cones in natural ways.
The purpose of this paper is to calculate the kernel of such actions.
First, we show that, when 𝐺 is acylindrically hyperbolic, the kernel of the natural action on every asymptotic cone coincides with the unique maximal finite normal subgroup

K

K(G)

of 𝐺.
Secondly, we use this equivalence to interpret the kernel of the actions on asymptotic cones as the kernel of the actions on many spaces at “infinity”.
For instance, if

G

M

G\curvearrowright M

is a non-elementary convergence group, then we show that the kernel of actions on the limit set

L(G)

coincides with the kernel of the action on asymptotic cones.
Similar results can also be established for the non-trivial Floyd boundary and the

groups with the visual boundary, contracting boundary, and sublinearly Morse boundary.
Additionally, the results are extended to another action on asymptotic cones, called Paulin’s construction.
In the last section, we calculate the kernel on asymptotic cones for various groups, and as an application, we show that the cardinality of the kernel can determine whether the group admits a non-elementary action under some mild assumptions.
Yeah, but how? Operationalizing the functions of the discourse-pragmatic marker yeah
Authors: Gibb-Reid Ben , Diskin-Holdaway Chloé
Published: January 2025

Discourse-pragmatic markers (DPMs) such as yeah are known for their multifunctionality, leading to challenges in coding for function in quantitative analyses. We provide an account of the incremental creation of a functional taxonomy for the DPM yeah using a decision tree and multilevel inter-rater reliability testing. Author 1 and rater 1 initially achieved a low agreement rate of 51 %, but upon consultation and adaptation of the taxonomy, came to an agreement of 95 %. Rater 2 used the revised taxonomy and achieved an agreement rate of 81 % (for primary [P] functions) and 91 % (for P and secondary [S] functions). Rater 3 achieved an agreement rate of 56 % (P) and 67 % (P + S) with author 1 + rater 1, but a higher agreement rate with rater 2 of 74 % (P) and 83 % (P + S). We draw on top-down and bottom-up, data-driven approaches, and discuss the future of DPM operationalization.

This paper presents the friction and wear behavior of alkali-treated corn husk fiber reinforced polyester composites. In this research, prepared the alkali treated corn husk fiber reinforced polyester composite through hand layup technique and investigated the physical, mechanical, and wear behavior of the composites. Prepared composite exhibited good hardness, impact, and tensile strength of 65.87, 9.25 J, and 48.52 MPa, respectively. Then, studied the friction and wear behavior by changing the applied load (30, 40, 50 N), sliding distance (500, 750, 1,000 m), and sliding velocity (2, 3, 4 m/s) using L9 Taguchi technique in pin-on-disk apparatus as per ASTM G-99. From the results, it is observed that, applied load has influenced more on wear and friction followed by sliding velocity and sliding distance. Increases in applied load and sliding distance led to increase the wear and friction. A decrease in sliding velocity led to a reduction in friction and wear. Further, analyzed the wear and friction using contour plot. Wear mechanism has been studied through SEM analysis.
Sensual Environmental Robots: Entanglements of Speculative Realist Ideas with Design Theory and Practice
Authors: Santer Steven C.
Published: January 2025

In response to this issue’s theme of Can robots be sensual? two propositions are discussed from a design researcher’s perspective. Four devices across two speculative projects Habitat Robots and Soil Protector Robots are presented. Speculative Realist ideas provide reasoning for design approaches to metaphorise sensed environmental data into multi-sensorial performances that the devices embody. Facilitated through the projects are philosophy of design concerns, such as asymmetrical relations, the nature of data, and language about the devices prefiguring sensorial expectations. The performative behaviours of these multi-sensorial robots evoke a sense of things by removing the truthiness of data and thereby emancipating language from privilege and expertise, subverting expectations of technology, and notions of urban Nature. Through Harman’s Quadruple Object, we speculate on asymmetricality within object relations, including between the devices and the practices of design itself. Thereby, allowing ontological design implications to be reviewed – where acts of designing in turn design us; design processes are not only entwined prefiguratively, but are companion output artefacts of these technological ecology interfaces. The devices bring together and physicalise questions of contextual boundaries and politics between humans, technology, and Nature.

Melt ponds are a common feature of the Arctic sea-ice environment during summer, and they play an important role in the exchange of heat and water vapor between the ocean and the atmosphere. We report the results of a time-series study of the CO2 dynamics within melt ponds (and nearby lead) and related fluxes with the atmosphere during the summer-to-autumn transition in the central Arctic Ocean during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. In late summer 2020, low-salinity meltwater was distributed throughout the melt ponds, and undersaturation of pCO2 in the meltwater drove a net influx of CO2 from the atmosphere. The meltwater layer subsequently thinned due to seawater influx, and a strong gradient in salinity and low-pCO2 water was observed at the interface between meltwater and seawater at the beginning of September. Mixing between meltwater and underlying seawater drives a significant drawdown of pCO2 as a result of the non-linearities in carbonate chemistry. By the middle of September, the strong stratification within the meltwater had dissipated. Subsequent freezing then began, and cooling and wind-induced drifting of ice floes caused mixing and an influx of seawater through the bottom of the melt pond. The pCO2 in the melt pond reached 300 µatm as a result of exchanging melt pond water with the underlying seawater. However, gas exchange was impeded by the formation of impermeable freshwater ice on the surface of the melt pond, and the net flux of CO2 was nearly zero into the pond, which was no longer a sink for atmospheric CO2. Overall, the melt ponds in this Arctic sea-ice area (both melt ponds and lead water) act as moderate sinks for atmospheric CO2.

Authors: Wexell Machado Luis Eduardo , Canese Valentina
Published: January 2025

In this article we examine the integration of artificial intelligence (AI) into language teaching at the Instituto Superior de Lenguas (ISL) of the Universidad Nacional de Asunción (UNA), Paraguay. We explore both the benefits and ethical challenges that emerge with the use of AI in educational contexts. Methodologically, this research is exploratory and follows a qualitative approach. Our sample includes eighty-eight ISL teachers, and we used a questionnaire to collect information on how AI is applied in teaching, learning, and assessment processes. The findings indicate that AI enhances educational efficiency by providing immediate feedback, customizing content to student levels, and enabling interactive activities. However, our study also reveals ethical concerns among teachers, especially regarding excessive reliance on AI, the potential reduction in human interaction during teaching, and issues of fairness in assessment. We conclude by emphasizing the importance of balancing AI usage with human critical judgment to ensure that technological tools effectively complement the teacher’s role in instruction and evaluation.

Aim: To investigate the changes in liver stiffness and immune-inflammatory markers associated with
obesity and the degree of hepatic steatosis in obese children and adolescents. Methods: A total of 76
obese children and adolescents aged 6–18 years, with body mass index percentiles >95th, were included
in the study. Patients with metabolic syndrome, diabetes mellitus, and chronic liver disease were excluded.
A control group of 44 patients of healthy and normal-weight children was included. Laboratory values from
the past month were analyzed using patient records. Shear wave elastography and ultrasound examinations
were performed on a single device by the same experienced radiologist. Results: The systemic immuneinflammation
index and pan-immune inflammation values were significantly higher in obese patients with
hepatic steatosis compared to obese patients without hepatic steatosis (p <0.001). Liver stiffness values
were significantly higher in steatotic patients compared to nonsteatotic patients (p <0.001). A significant
difference was observed between hepatic steatosis grades in terms of immune-inflammation index and
pan-immune inflammation value values (p <0.001). There was a strong, positive, statistically significant
correlation between liver stiffness and immune-inflammation index and pan-immune inflammation value
(p <0.05). Conclusions: Immune-inflammatory biomarkers and shear wave elastography may provide
valuable insights into the diagnosis and follow-up of inflammation and fibrosis in the evaluation of hepatic
steatosis in obese children and adolescents.
