Hunger, monstrosity, and race in Helen Oyeyemi’s White is for witching
Authors: STOICA LAURA-VICTORIA
Published: February 2025

Helen Oyeyemi is a British-Nigerian writer whose works explore fluid articulations of ethnicity, race, and identity. In her third
novel, White is for Witching (2009), a White British girl, Miranda,
and her Black British friend Oreare are “devoured” by the cycle
of oppression and consumption enacted by Miranda’s forefathers
upon their Black servants. Thus, the difficulty of upholding racial
and ethnical binary oppositions becomes the main recurrent
theme in Oyeyemi’s novels and short fiction. By extensively using
folklore and mythology, Oyeyemi delves into the human psyche
to explore the universal fear of the Other, and the construction
of identity. Most importantly, her novels seek to find out whether
globalization and the readily available access to other cultures have
facilitated or hindered genuine communication. Focusing on intercultural hybridity and communication, her novels strongly encourage a postcolonial interpretation. White is for Witching tackles
borders and the construction of borders as part of racial and national identity. This article will seek to analyze and deconstruct the
consumption of the Black Body as a representation of racial an -
xi e ties and transgenerational trauma, while also looking into the
transformations performed by Helen Oyeyemi on the Gothic
genre in an attempt to accommodate postcolonial narratives. In
trying to tread the fine line between fiction and reality, the personal
and the collective, Miranda and Ore’s story will be explored in
order to reinforce the issue of liminality and the novel’s articulation of the “transatlantic Gothic” (Porter, 2013: 23). The article
will call into question the relationship between race and its representations, while also highlighting the role of imagination in the
delineation of group identity.
Victor Hugo and John Keats: A Psychological Landscape for Poetic Dreams
Authors: HOBBI RANDA
Published: February 2025

This paper addresses poetic dreams from a psychological viewpoint by comparing two Romantic poets, John Keats and Victor
Hugo. The study proceeds through the analysis of three major elements that are significant in the creation of Romantic identity, that
is: memories, sleep and dreams. Throughout the poetic example, we
attempt at a psychological reading of the depicted images and expressions that conceal symbolic meaning, mainly those in relating to natural elements. The examples analysed in this paper also raise the
question of the collective unconscious as a way of joining human
thoughts and needs through poetic representations of dream codes.
This objective is accomplished by highlighting two psychological components: the conscious and the unconscious, as defined by Freud and
Jung. The paper hence demonstrates the tension that both aspects of
the psychological self can generate within the poetic extracts through
deconstructing and constructing the self itself. The search for the
reconciliation of each side helps define a new poetic Self.
Organizational Commitment and Turnover Intention of Southland College Employees
Authors: Taquiso Elwin L.
Published: February 2025

Organizational Commitment refers to the bond between the employee and the organization where he/she feels fit in and has understood the organizational goals and objectives thereby contributing actively to its attainment. Turnover Intention refers to the plan or resolution of the employee to leave the organization at a specific time. The purpose of the study was to determine the organizational commitment and turnover intention of Southland College employees. Employing a quantitative research design, the study used 165 stayers and leavers. They answered a validated self-made questionnaire with a Likert scale. Statistical techniques used were the mean and multiple regression analysis and dominance analysis. Findings revealed that employees have normative commitment who feel obligated to the organization although they are no longer happy with the roles they perform while turnover intention is strongly correlated to conflict of interest, confidentiality, and promotion among the factors under organizational loyalty. The study concludes that organizational commitment is the primary reason why employees chose to stay and among the variables, the structural variables affecting turnover, work environment, independence, and communication are among the top three (3) reasons for quit thought.

Challenges of Family-School Communication at Zibo Zhangdian District No. 5 Middle School, Zibo City, China
Authors: Hui Yu , Balinas Jesse
Published: February 2025

This study aimed to explore the challenges of family-school communication at Zibo Zhangdian District No. 5 Middle School in Zibo City, China. Using a descriptive qualitative method, the research sought to identify the barriers to effective communication between parents and teachers. The study specifically aimed to describe the challenges faced by parents in communicating with teachers, the difficulties teachers encounter when interacting with parents, and to propose an intervention plan to improve these communication practices. The analysis revealed that a significant barrier is the perceived lack of teacher responsiveness, contributing to feelings of disempowerment among parents. Additionally, the lack of timely and detailed communication highlighted the need to bridge communication gaps and offer more opportunities for open dialogue. Misalignment between digital communication preferences and parents’ ability to navigate these tools further exacerbated the issue. The study also found that communication challenges were influenced by socio-cultural norms and expectations, making clear, timely, and reciprocal communication vital for student success. The findings emphasized the need for a balanced, inclusive, and strategic approach to family-school communication, where both teachers and parents share responsibility in addressing students’ needs.

Air pollution in Nigeria’s urban areas, driven by rapid urbanization, industrialization, and human activities, poses significant public health and environmental challenges. This review discusses the sources, trends, and impacts of air pollution across the country, highlighting the seasonal and regional variations in air quality. Major sources of pollutants, including industrial emissions, vehicular exhaust, biomass burning, and waste management practices, are examined, along with their contribution to particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), sulfur oxides (SOx), and 1-nitropyrene (1-NP) levels. The health impacts of air pollution are profound, affecting respiratory, cardiovascular, reproductive, and neurological systems. Vulnerable groups, including children and pregnant women, are particularly at risk. Furthermore, air pollution contributes to environmental degradation, economic losses, and reduced life expectancy. The review emphasizes the need for effective policies and interventions to mitigate air pollution and improve public health. Addressing these issues is crucial for safeguarding the well-being of Nigeria’s growing urban population and ensuring sustainable development. The urgent need for comprehensive air quality management strategies and public awareness initiatives is underscored to prevent the long-term consequences of air pollution on health and the environment. By implementing effective policies, embracing cleaner technologies, and raising public awareness, Nigeria can tackle air pollution and protect the well being of its growing urban population. A commitment to these measures will not only improve air quality but also contribute to sustainable development and a healthier future for all.

Published: February 2025

El camote (Ipomoea batatas L.) es un cultivo de mucha importancia por su valor nutricional y agrícola. Sin embargo, existe una carencia de información específica sobre la fertilización para optimizar su producción. Este estudio tuvo como objetivo evaluar el comportamiento agronómico de la variedad introducida de camote INIAP Toquecita bajo diferentes tipos de fertilización química. La investigación se realizó en La Pipona, cantón Rocafuerte, Manabí, empleando un Diseño de Bloques Completamente al Azar (DBCA) con tres repeticiones y ocho tratamientos (siete formulaciones químicas y un testigo). Se evaluaron variables como porcentaje de prendimiento, índice de clorofila, número de guías por planta, rendimiento foliar, número de raíces comerciales y rendimiento. El análisis estadístico se efectuó mediante ANOVA utilizando el software InfoStat 2020, complementado con la prueba de Tukey (p≤0,05) para la comparación de medias. Los resultados demostraron un efecto significativo de la fertilización química en el desarrollo y productividad del camote. El tratamiento 2 (N 80 Kg/ha; P 20 Kg/ha) tuvo mayor rendimiento con 18,33 t.ha⁻¹ de raíces comerciales, superando al testigo y demás tratamientos. Esto sugiere que la formulación del tratamiento 2 da buenos resultados con la variedad de camote INIAP Toquecita.

Luxury Real Estate and Climate Resilience: A Qualitative Analysis of Sustainable Practices and Tangible Impacts
Authors: Gabelaia Ioseb , Boyce Joseph
Published: February 2025

This research explored luxury real estate and its growing commitment to sustainable practices in response to the global climate crisis. Existing research on vertical green systems lacks evidence of long-term economic feasibility. Today, developers are pioneering vertical green cities, incorporating rooftop gardens and sustainable materials to reduce energy consumption and promote biodiversity in dense urban settings. The authors explored how luxury developments can reduce carbon footprints while maintaining appeal and highlight efforts to impact more comprehensive urban planning. With qualitative methodology, the authors intended to reveal the effectiveness of sustainable practices in luxury real estate, assessing their real-world impact on carbon reduction, resource preservation, and urban biodiversity. The interviews were grounded in a literature review to demonstrate trustworthy results and add reliability. Besides, the authors acknowledge limitations such as potential self-report bias. The results offered insights into luxury real estate to redefine urban living through sustainable innovations and support the global movement toward net-zero emissions and climate-resilient cities. One of the significant results of this research was accepting the need for sustainable approaches; however, resistance was driven by not having sustainable reports on luxury real estate.
Circular Economy Model for The Use of Recyclable Waste in Tropical Countries
Authors: Segura Osuna Jenny Alexandra , Rodríguez Miranda Juan Pablo
Published: February 2025

In every economy in its productive processes there are wastes that can be but are not used, hence models such as those proposed by the circular economy, allow to reduce the amount of waste that ends up in landfills and that become polluting agents of the environment. This article proposes a model for the use of inorganic waste for countries located in tropical areas, where activities related to tourism and crafts are carried out, taking into account the precepts of the circular economy and the orange economy. This model is very useful since it not only contributes to the economy and the generation of income for vulnerable populations, but also contributes to the sustainability of the resources of one of these tropical countries.

Convection-generated gravity waves in the tropical lower stratosphere from Aeolus wind profiling, GNSS-RO and ERA5 reanalysis
Authors: Ratynski Mathieu , Khaykin Sergey , Hauchecorne Alain , Alexander Joan , Mariaccia Alexis , Keckhut Philippe , Mangin Antoine
Published: February 2025

Abstract. The European Space Agency's Aeolus satellite, equipped with the Atmospheric LAser Doppler INstrument (ALADIN), provides global provides near-global wind profiles from the surface to about 30 km altitude. These wind measurements enable the investigation of atmospheric dynamics, including gravity waves (GWs) in the upper troposphere and lower stratosphere (UTLS). This study analyzes ALADIN wind observations and ERA5 reanalysis, by deriving GWs kinetic energy (Ek) distributions, examining their temporal and spatial variability throughout the tropical UTLS. A prominent hotspot of enhanced GW activity is identified by Aeolus, migrating from the Indian Ocean in Boreal Summer to the Maritime Continent in Boreal Winter, closely matching outgoing longwave radiation minima and thus highlighting convective origins. Results show that ERA5 consistently underestimates Ek in convective regions, especially over the Indian Ocean, where conventional wind measurements are sparse. Additional comparisons with Global Navigation Satellite System Radio Occultation (GNSS-RO) measurements of GW potential energy (Ep) corroborate these findings and suggest significant underrepresentation of convection-driven wave activity in reanalyses. A multi-instrumental exploratory analysis also allows to verify the empirical grounding of the established Ek to Ep ratio, as well as the wavelength of the waves retrieved by Aeolus. By filling critical wind data gaps, Aeolus emerges as a key tool for improving the representation of GWs, particularly in remote tropical regions. When combined with GNSS-RO measurements, Aeolus data provides new insights into how convective processes drive GW generation, revealing opportunities to refine reanalysis products and model parameterizations, as well as improving the energy ratio.

Abstract. Nitryl chloride (ClNO2) is a reservoir species of chlorine atoms and nitrogen oxides, both of which play important roles in atmospheric chemistry. To date, all ambient ClNO2 observations have been obtained by chemical ionization mass spectrometry (CIMS). In this work, Thermal Dissociation Tunable Infrared Laser Differential Absorption Spectrometer (TD-TILDAS) is shown to be a viable method for quantifying ClNO2 in laboratory and field settings. This technique relies on the thermal dissociation of ClNO2 to create chlorine radicals, which undergo fast reactions with hydrocarbons to produce hydrogen chloride (HCl) that is detectable by the TILDAS instrument. Complete quantitative conversion of ClNO2 to HCl was achieved at temperatures > 400 °C, achieving 1 Hz measurement precision of 11 ± 1 pptv (3σ limits of detection of 34 ± 2 pptv) during laboratory comparisons with other ClNO2 detection methods. After blank- and line loss-corrections, method accuracy is estimated to be within ± 5 %. Performance metrics of TD-TILDAS during ambient sampling were a 1 Hz precision of 19 ± 1 pptv and 3σ limits of detection of 57 ± 3 pptv), which is directly comparable to previously reported ClNO2 detection by quadrupole CIMS. Thus, TD-TILDAS can provide an alternative analytical approach for a direct measurement of ClNO2 that can complement existing datasets and future studies. The quantitative nature of TD-TILDAS also makes it a potentially useful tool for the calibration of CIMS instruments. However, interpretation of ambient data may be potentially complicated by interference from unaccounted-for sources of thermolabile chlorine.
Rethinking antibiotic prophylaxis in orthopaedic oncology: insights from a cohort study of endoprosthetic infections
Authors: Azamgarhi Tariq , Gerrand Craig , Warren Simon
Published: February 2025

Abstract. Introduction: Endoprosthetic replacement (EPR) is the preferred limb salvage method for musculoskeletal tumours involving bone; however, infection rates range from 8 % to 12 %. We investigated the impact of antibiotic prophylaxis at primary implantation on the development of prosthetic joint infection (PJI). Methods: We conducted a retrospective analysis of patients who underwent primary EPRs between 2010 and 2021. Prosthetic joint infections were identified and classified according to criteria from the European Bone and Joint Infection Society (EBJIS). The follow-up period extended until an infection was identified, subsequent surgery for non-infectious reasons occurred or the last known follow-up was conducted. For all primary procedures, we collected details of postoperative complications at the surgical site, including superficial wound infections, delayed wound healing and wound dehiscence. PJIs were divided into two groups. The first group included patients with an uncomplicated postoperative course, while the second comprised those with either postoperative wound problems or infections from an identifiable source. Results: Out of 1064 patients, 73 (6.9 %) developed PJI within a median follow-up of 25.6 months (IQR 8.8–52.7). A total of 26 % of PJIs were attributed to primary implantation, while 74 % of PJIs were due to secondary causes, with 47 % having wound complications and 27 % presenting acutely. The microbiological profiles between groups differed significantly, with infections from skin flora related to primary implantation and a high proportion of other bacteria (Gram-negatives and enterococci) linked to secondary infections. Conclusions: Skin flora are likely responsible for infections related to the primary procedure, and antibiotic prophylaxis should be optimised accordingly. Additional measures are needed to prevent secondary infections.

Abstract. Reconstructions of palaeo-ice-stream activity provide insight into the processes governing ice stream evolution over millennial timescales. The northwestern sector of the Laurentide Ice Sheet experienced a period of rapid retreat driven by warming during the Bølling–Allerød (14.7–12.9 ka) that may have contributed significantly to global mean sea level rise during this time. Therefore, the northwestern Laurentide Ice Sheet provides an opportunity to investigate ice sheet dynamics during a phase of rapid ice sheet retreat. Here, we classify coherent groups of ice-flow-parallel lineations into 326 flowsets and then categorise them as ice stream, deglacial, inferred deglacial or event flowsets. Combined with ice-marginal landforms and a new ice margin chronology (Dalton et al., 2023), we present the first reconstruction of ice flow dynamics of the northwestern Laurentide Ice Sheet at 500-year time steps through the last deglaciation (17.5–10.5 ka). At the local Last Glacial Maximum (17.5 ka), the ice stream network was dominated by large, marine-terminating ice streams (> 1000 km long) that were fed by the Cordilleran–Laurentide ice saddle to the south and the Keewatin Dome to the east. As the ice margin retreated onshore, the drainage network was characterised by shorter, land-terminating ice streams (< 200 km long), with the exception of the Bear Lake and Great Slave Lake ice streams (∼ 600 km long) that terminated in large glacial lakes. Rapid reorganisation of the ice drainage network, from predominantly northerly ice flow to westerly ice flow, occurred over ∼ 2000 years, coinciding with a period of rapid ice sheet surface lowering in the ice saddle region. We note a peak in ice stream activity during the Bølling–Allerød that we suggest is a result of increased ablation and a steepening of the ice surface slope in ice stream onset zones and the increase in driving stresses that contributed to rapid ice drawdown. The subsequent cessation of ice stream activity by the end of the Bølling–Allerød was a result of ice drawdown lowering the ice surface profile, reducing driving stresses and leading to widespread ice stream shutdown.

VAMPIRES AND STAR-CROSSED LOVERS: SECONDARY TEACHERS’ REASONING ABOUT THE CONNECTIONS BETWEEN MULTIVARIATE DATA AND VISUALIZATION
Authors: LEGACY CHELSEY , ZIEFFLER ANDREW , RAO VIMAL , DelMAS ROBERT
Published: February 2025

As ideas from data science become more prevalent in secondary curricula, it is important to understand secondary teachers’ content knowledge and reasoning about complex data structures and modern visualizations. The purpose of this case study is to explore how secondary teachers make sense of mappings between data and visualizations, especially depictions of multivariate relationships. The participants were 14 in-service secondary teachers who were video recorded as they worked through three sets of activities. In these activities, participants created a visualization (network graph) from multivariate data, encoded raw data for several attributes from visualizations depicting multivariate relationships, and structured data into a tidy format. With minimal instruction, participants were able to create visualizations when given data representing multivariate relationships. They were also able to structure non-tidy data into a tidy format with some scaffolding and discussion. Notably, creating data tables from visualizations, especially relational tables, seemed more challenging for them. These results provide insight into secondary teachers’ reasoning about connections between multivariate data and visualization.

El periodismo de datos es una de las especialidades con mayor proyección en los medios de comunicación, pero también una de las que mayores exigencias técnicas conlleva. Los lenguajes de programación y las herramientas digitales adquieren aquí un protagonismo especial e implican mayores esfuerzos en la formación de periodistas. Para analizar la evolución del uso de la programación y de las herramientas digitales en españa, se ha llevado a cabo un trabajo de campo longitudinal en dos etapas. Primero, se entrevistó a un profesional de cada medio de comunicación que contara con un equipo consolidado de periodismo de datos.  Se consiguieron diez entrevistas en 2021. Este proceso se repitió en 2024 con un total de ocho profesionales de ocho medios para comprobar su evolución durante esos tres años. Los resultados muestran que R, Python y JavaScript son los lenguajes más utilizados en las redacciones españolas para la realización de las piezas periodísticas con datos, mientras que Excel, Google SpreadSheets, Datawrapper y Flourish son las herramientas mejor valoradas para la obtención, limpieza, análisis y visualización de los datos. POr otra parte, se observa además que la inteligencia artificial es una tecnología en auge que, aunque los periodistas utilizan con cautela, se emplea principalmente en la creación y curación de código, al no conseguir resultados totalmente fiables en las pruebas que han realizado para el análisis de datos.
Cobertura del suicidio en medios iberoamericanos: Análisis de contenido y encuadre informativo

La cobertura informativa sobre el suicidio debe tener especial tratamiento por parte de periodistas y medios de comunicación. Estudios previos confirman que la narrativa puede desencadenar imitadores e incluso pensamientos suicidas en personas con trastornos de salud mental. En este sentido, la Organización Mundial de la Salud (OMS) y la Organización Panamericana de la Salud (OPS) han brindado varias directrices para la cobertura de este tema. Esta investigación analiza la cobertura del suicidio en los principales medios de comunicación de 20 países iberoamericanos a partir de un análisis de contenido y de encuadre informativo de diseño cuanti-cualitativo. Los resultados arrojan que la explicación al suicidio más común es multicausal seguida por la ambiental o de contexto. En línea con las recomendaciones de la OMS-OPS, la mayoría de informaciones intentan educar al público, aunque todavía sigue siendo una materia pendiente indicar en las notas sobre cómo y dónde buscar ayuda. Se observó que en general la mayoría de las informaciones utilizan fuentes mixtas, tanto de expertos como familiares/amigos de las víctimas. Sin embargo, del análisis cualitativo se extrae que algunos encuadres están salpicados de tópicos y lugares comunes, recayendo en coberturas que se alejan de las directrices, informando sobre detalles del hecho o estableciendo relaciones causa-efecto imposibles de verificar. En los casos que se evidenciaron enfoques constructivos pesó más el tono narrativo explicativo, aportando datos con los que hacerse una idea clara de la complejidad del tema.
La evolución de los debates televisivos de la Transición (1975-1982): fórmulas de emisión, programas clave y legado

Published: February 2025

Este artículo analiza la evolución de los programas de debate en Televisión Española (TVE) durante la Transición española (1975-1982), un periodo crucial en el que España se adaptaba a la democracia tras la dictadura franquista. Los programas de debate se transformaron significativamente, pues incorporaron formatos que promovían la diversidad de opiniones y técnicas de moderación mejoradas. La presencia de invitados con múltiples orientaciones políticas y la superación de las restricciones de censura franquista permitieron discutir temas sensibles y reconfigurar narrativas históricas, al tiempo que contribuían a formar una opinión pública más crítica y plural. La metodología de estudio destaca por utilizar tanto fuentes primarias como secundarias que incluyen materiales de archivo de RTVE y fuentes hemerográficas, corporativas e institucionales. Esto subraya la importancia de un enfoque comprehensivo para entender el impacto social de estos programas. Además, el presente trabajo desglosa la evolución de los programas en varias etapas, desde los formatos iniciales más controlados hasta debates más dinámicos y polémicos que reflejaban una sociedad y una televisión en transformación. Aquellos cambios no solo ilustraron la adaptación de los formatos de debate a un entorno democrático emergente, sino que también pusieron de manifiesto cómo la televisión pública pudo influir activamente en el proceso de democratización. Finalmente, la contribución de los programas de debate a la democracia española se evalúa en cómo facilitaron un foro para la discusión pública y permitieron la expresión de una amplia gama de opiniones y la participación ciudadana, factores fundamentales para fortalecer el tejido social y cívico del país.
Estrategias de polarización discursiva de los medios digitales (ultra)conservadores españoles en noticias sobre feminismo
Authors: Arrieta Castillo Carolina
Published: February 2025

El periodismo sirve de caja de resonancia de las ideas políticas y permite fijar el debate público. El feminismo y el cuestionamiento que de él hacen los partidos de ultraderecha es uno de los temas que protagonizan ese debate. En este artículo se analiza el tratamiento que cinco medios digitales (ultra)conservadores de ámbito español dan al tema del feminismo, con el propósito de comprender si este ecosistema mediático contribuye a la difusión de antifeminismo y misoginia digital en el debate público. Se realiza un análisis de contenido y discursivo de carácter mixto, cualitativo y cuantitativo, de 200 piezas periodísticas de los diarios La Razón, Libertad Digital, Okdiario, The Objective y Vozpópuli. La recolección de la muestra se realizó en orden inverso a partir del 31 de diciembre de 2023, con el objetivo de seleccionar 40 piezas periodísticas de cada medio. La ficha de codificación incluye categorías como el tipo de representación, temas y lugares comunes de la manosfera y del feminismo y convenciones y prácticas periodísticas. Los resultados indican un escenario de representación no positiva del feminismo en el cual los medios –a excepción de The Objective– ofrecen una aproximación mayor a los argumentos de la manosfera que a los temas de la agenda feminista. Todos hacen un despliegue de estrategias periodísticas y discursivas –como la inclusión de fuentes poco relevantes, los titulares valorativos o la utilización de lenguaje vejatorio– próximas a las prácticas pseudoperiodísticas. Las estrategias de polarización discursiva son recurrentes en las noticias de medios digitales (ultra)conservadores a la hora de difundir agenda antifeminista.
La radio en España ante la Transición Ecosocial: temáticas, puntos de vista narrativos, carencias y retos
Authors: Peralta-García Lida , Sanz-Hernando Clara
Published: February 2025

Esta investigación propone un mapeo y categorización de la programación radiofónica española vinculada a la Transición Ecosocial (T.E.), entendida como un proceso que da cabida a iniciativas y proyectos de transición hacia sociedades más ecológicas, solidarias, justas, equitativas, inclusivas, diversas y feministas. El marco teórico propone una aproximación a los conceptos de Información-Diagnóstico (I.D.) e Información-Antídoto (I.A.). Esta última forma de comunicación va más allá de la visibilización de los problemas y la búsqueda de causalidades. Propone alternativas y fomenta la participación activa de la audiencia. El análisis pretende poner en valor aquellos programas radiofónicos que ofrecen claves para comprender la importancia de actuar bajo el foco de los beneficios de adoptar la T.E. en su multitud de formas y posibilidades. Mediante el empleo de las metodologías cuantitativa y cualitativa, se analizan 110 programas radiofónicos de 21 emisoras españolas, categorizados según una subdivisión temática. Las hipótesis asumen un compromiso de la radio con la Transición Ecosocial, así como un predominio del abordaje de contenidos más cercanos al diagnóstico que al antídoto. Los resultados confirman los presupuestos de partida y muestran que RNE Radio 5, con 32 programas relacionados con la T.E. (29,1 %), se sitúa a la cabeza de las emisoras comprometidas con temáticas propias de Transición Ecosocial.  La categoría Calidad de vida ocupa el mayor espacio programático, frente a la Migración y al colectivo LGBTI+, que acaparan el menor número de programas especializados.
Más allá de la paridad de género en el politainment: cuando la información política se convierte en espectáculo televisivo, el androcentrismo persiste
Authors: Pecino Isaac , Gómez-Puertas Lorena
Published: February 2025

En un contexto donde la televisión aún es clave como medio de influencia en la opinión pública, y desde un posicionamiento crítico feminista, este estudio explora la perpetuación de los sesgos de género en la comunicación política que se desarrolla en formatos de infoentretenimiento. El objetivo general es evaluar los roles y las funciones de las personas participantes en los debates de actualidad del politainment desde una perspectiva de género. Para ello se adapta un diseño de análisis de contenido a una muestra no probabilística del período comprendido entre enero y mayo de 2024 (más de 35 horas) que cubre tres debates de actualidad política televisiva de formato, contenidos, franja de emisión y cuota de pantalla similar durante la temporada 2023/24: La hora de La 1 (La 1, Corporación Radio Televisión Española, 11,5 % share), La mirada crítica (Telecinco, Mediaset España, 12,3 % share) y Al rojo vivo (La Sexta, Atresmedia, 11,5 % share). El análisis permite detectar la relevancia de las mujeres presentes en estos espacios de debate, dependiendo del rol que ejercen (moderador, tertuliano, relator, fuente, experto, reportero, corresponsal, o especialista). Los principales hallazgos señalan la infrarrepresentación de la mujer en roles clave como el de experta (8,51 %), frente a la feminización de otros como el de relatora, (63,16 %) sin voz propia en el debate político espectacularizado. Esta desigual distribución en las funciones ejercidas por las mujeres reproduce su exclusión de la esfera pública también en los formatos de politainment, donde la mirada androcéntrica se impone a su participación efectiva como sujetos políticos.
