Published: January 2024

Los procesos de consultoría tienen relación con la prestación de servicios profesionales no normalizados, es decir, cuyas características o especificaciones técnicas no pueden ser reguladas o aprobadas; por tanto, estas características o especificaciones no llegarán a ser homogéneas y comparables en las mismas condiciones. Esta clase de procedimientos tienen por objeto identificar, auditar, planificar, elaborar o evaluar estudios y proyectos de desarrollo, en sus niveles de pre factibilidad, factibilidad, diseño u operación. Los objetivos del presente trabajo es analizar y determinar la importancia de la legalidad -como principio aplicable del Derecho Administrativo- en la práctica de la contratación pública, en cumplimiento de las disposiciones legales. Para ello se utilizó una metodología basada en una investigación no experimental, se basó en la observación de una o más características, bajo una modalidad cuali- cuantitativa porque ofrece una mejor recopilación de información de ambas modalidades; cualitativa, porque trata de la adquisición de datos no numéricos para entender todo tipo de conceptos, opiniones o experiencias que se han vivido; y, cuantitativa, debido a que se recopilan datos numéricos y estadísticos. Los resultados del estudio arrojaron la necesidad de cumplir con la obligación de adecuar los pliegos y demás instrumentos técnicos, a las disposiciones legales establecidas por la normativa aplicable a la contratación pública, por parte del Servicio Nacional de Contratación Pública (SERCOP). Esto fue considerado para determinar que el principio de legalidad debe ser el pilar fundamental para el ejercicio del Derecho Administrativo en la contratación pública en el Ecuador, para evitar arbitrariedades y abusos por parte de las partes que forman parte del acuerdo.

Su origen se remonta al año 2018, cuando se creó el Boletín Crusamtino, medio de divulgación, en formato impreso. Se propone en el año 2021 una renovación y cambio. El tipo de investigación es cualitativa descriptiva, la metodología utilizada fue desarrollada en dos fases: mediante una encuesta (PreTest) a una muestra de noventa y ocho (98) personas de la comunidad del CRUSAM para identificar los cambios y mejoras que podrían hacerse;  recomendaron un cambio de imagen del Boletín Crusamtino. En la segunda fase, (PosTest) la muestra de personas encuestadas, seleccionados de manera aleatoria, aseguraban la viabilidad, comunicación, estética y eficacia de la nueva conexiones CRUSAM, como medio de divulgación, gracias al sondeo de la primera encuesta, se concluye que la gran mayoría escogió el nombre de conexiones CRUSAM, y se aplicaron grandes cambios en cuanto a cuerpo editorial, diseño, línea gráfica, estética, segmentos, proceso de digitalización, diagramación y comunicación en base a las recomendaciones recibidas.
Problemas orais em residentes rurais: perspetiva autopercebida
Authors: Jesus Ana Catarina , Bizarra Fátima
Published: January 2024

Introdução: Residentes em meios rurais apresentam maior prevalência de cárie dentária, depósitos de cálculo, perda dentária e dor associada à cavidade oral (Barbato et al., 2007). A autoperceção que cada um tem da doença é influenciada, entre outros fatores, pelo contexto sociocultural em que o indivíduo está inserido (Andersen et al., 2005). Em Portugal, a falta de perceção da necessidade de tratamentos dentários é uma das principais razões para não consultar um profissional de saúde oral (Melo et al., 2017). Objetivo: O objetivo deste estudo foi determinar a existência de problemas orais autopercebidos numa população adulta residente num meio rural. Materiais e Métodos: A amostra deste estudo observacional transversal foi constituída por 364 indivídos do concelho de Mértola, sendo considerada estatisticamente significativa tendo em conta o tamanho da população. Foi estratificada por sexo, grupo etário e freguesia de residência, permitindo alcançar a representatividade e a extrapolação dos resultados para toda a população mertolense. Durante janeiro e março de 2022, os participantes responderam a um questionário constituído por nove questões de escolha múltipla, sobre hábitos e comportamentos em SO. Os dados foram analisados no software SPSS® (versão 26.0), considerando um nível de significância de 0,05. Resultados: A idade média foi 53,2 (±19,02) anos, sendo que 49,7% (180) são mulheres. Somente 9,1% (33) têm formação superior. Cerca de 29,3% afirma não ter uma cavidade oral saudável. A maioria (92,8%) relatou ter pelo menos um problema oral atual, como hemorragia gengival (45%), xerostomia (36,2%) e dor no momento da entrevista (21,5%). Quase metade (48,6%) refere ter sensibilidade dentária, maioritariamente as mulheres (p=0,027). A maioria já perdeu dois ou mais dentes (75,4%), porém, apenas 37,8% os substitui através de reabilitação oral. Quanto mais velho é o grupo etário, mais os participantes relatam ter problema orais (p<0,001), como cálculo (p=0,043), xerostomia (p<0,001), mobilidade (p<0,001) e/ou perda dentária (p<0,001). Quanto mais jovem é o grupo, mais referem sensibilidade (p=0,002) e/ou gengivite (p<0,001). Conclusão: Estes dados refletem a falta de perceção da necessidade de tratamento, que influencia diretamente a saúde oral desta população. Sugere-se a realização de observação oral futura, para avaliação da condição oral destes indivíduos.
A manipulação segura de medicamentos citotóxicos por profissionais de Farmácia através da implementação de programas de formação: revisão sistemática das diretrizes internacionais
Authors: Moreira Fernando , Pinho Cláudia , Santos Marlene , Serdoura Mélanie , Jesus Ângelo
Published: January 2024

Introdução: A manipulação de medicamentos citotóxicos constitui uma série de procedimentos que exigem o cumprimento rigoroso das diretrizes estabelecidas, por forma a limitar a exposição ocupacional por parte dos profissionais de saúde. Uma das principais barreiras comummente identificadas para a manipulação segura de medicamentos citotóxicos é o fraco investimento nas competências e conhecimentos dos profissionais envolvidos nestas tarefas (Fazel et al., 2021). Objetivos: Este estudo tem como objetivo realizar uma revisão sistemática para identificar a formação técnica e científica específica mais relevante para os profissionais de farmácia que realizam ou pretendem realizar a preparação de medicamentos citotóxicos, bem como os momentos mais críticos para a sua realização. Material e Métodos: Foi efetuada uma pesquisa nas bases de dados PubMed, Cochrane e Lilacs sobre diretrizes internacionais que abordassem a manipulação de medicamentos citotóxicos, publicadas entre 2004 e 2022. Foram incluídos documentos escritos em inglês, espanhol ou português que abordassem a formação em manipulação de citotóxicos para profissionais de farmácia. A seleção, análise e tratamento dos resultados obtidos decorreu de acordo com os princípios PRISMA. As diretrizes selecionadas foram avaliadas com a ferramenta AGREE-II e sintetizadas quanto aos seus conteúdos específicos e momentos recomendados para a formação e avaliação. Resultados: Foram incluídas 18 diretrizes na presente revisão sistemática. A pontuação total mediana da ferramenta AGREE II para as diretrizes foi de 91 pontos (em 168), com uma qualidade global mediana de 49% (IQR, 41%-63%). Sete diretrizes obtiveram uma pontuação global inferior a 45% e apenas uma diretriz obteve uma pontuação global superior a 70% (International Society of Oncology Pharmacy Practitioners, 2022). Treze diretrizes recomendavam a formação antes de se iniciar a preparação de citotóxicos e regularmente, após a iniciação em funções. Os conteúdos específicos mais frequentemente referidos como cruciais nos programas de formação foram a gestão de derrames (n=11) e a utilização de equipamento de proteção individual (n=9). Conclusões: Foi possível reconhecer a importância da realização de programas educacionais para os profissionais de farmácia que preparam ou pretendem preparar medicamentos citotóxicos. A combinação de aprendizagem teórica e prática é aconselhável, sendo também recomendada a simulação de práticas de manipulação, sob supervisão.

A Qualitative Study into the Experiences and Motivation of Filipino Healthcare Professionals in Pre- and Post-COVID-19 Pandemic
Authors: Bueno Alfred Anthony , Buhisan Angel May M. , Nayal Kayle Erika Shayne P. , Manaois Jason O.
Published: January 2024

Motivation is among the core components of work performance among individuals and organizations, particularly for workers facing challenging and complex work environments. The Self-Determination Theory analyzes the key elements of one’s motivation, focusing on intrinsic and extrinsic motivational patterns. Healthcare workers face specialized tasks (e.g., providing patient care) and daily challenges (e.g., weighty workloads) that test their motivation to pursue their chosen profession. In this article, the self-determination theory is applied to clarify both (a) experiences and (b) challenges of these healthcare workers employed in Cagayan de Oro City. The current study utilized an online qualitative survey to obtain responses from the target sample. The data were coded and thematically analyzed. Results indicate that participants experience both ends of the motivational continuum; some experience a personal inherent desire for continued learning and professional development, while others are motivated in their profession for increased financial compensation and benefits. These workers’ challenges include workload challenges, conflicts with colleagues, changes in the workplace environment, and difficulties encountered through patient interaction. Policymakers should focus on providing a balance between boosting healthcare workers’ monetary compensation, providing further growth and development in their field, and enhancing workplace conditions; improvements in their motivation level can be anticipated to increase.
Oduduwa: Through the Eyes of a Wood Carver
Authors: Oligbinde Samuel Rotimi
Published: January 2024

History is the chronological and integrated account of relationship between man, event, person, time and places. The Yoruba history has long been at the mercy of the West due to the disinterest of the Yoruba people in the preservation and propagation of their Tradition, Culture and Religion. This has led to the publication of volumes of misinterpretations, flawed and shallow analysis of Yoruba religion for which the Yoruba could only be grateful. Oduduwa is one of the most important Yoruba Progenitor in the history of the Yoruba tribe in Nigeria. He was a powerful leader under whom the nucleus of the Yoruba race migrated into this land from their original home in Ile-Ife. He was a man of great leadership skills, understanding and repute. He is one of the most discussed Yoruba Deity with different point of view because various scholars have not come to a conclusion of who he was. Unfortunately, from our oral Yoruba traditional history there is no descriptive analysis of how Oduduwa looked like but, however, a sculptor in person of Lamidi Fakeye, a traditional wood carver, carried out a commissioned work of Oduduwa in wood carving, describing what he looks like through a story which surrounds the creation of the world. The paper intends to discuss the life of Oduduwa and a conceptual analysis of the wood carving executed in his form. The background data for this paper came largely from textbooks, articles, field work, documentation, archival records, and observation of physical artefacts.

The Influence of Corporate Governance on Market Capitalization: Evidence from Listed Firms of DSE
Authors: Uddin Dr. Md. Hasan
Published: January 2024

This study examines the relationship between the corporate governance (CG) mechanisms related to board size (BS), board independence (BI), board committees (BC), ownership structure (OS), and the market capitalization of companies listed in the Dhaka stock exchange (DSE). Secondary data from 41 listed firms in Dhaka Stock Exchange during the period of 2015 to 2022 is utilized in this study. The ordinary least square, regression techniques were applied on the panel data collated to estimate the model. The findings reveal a significant positive impact of board committees and board independence on the market capitalization of the companies, while ownership structure shows a significant negative effect on the market capitalization of the companies. Thus, the results suggest that board committees and board independence have a crucial role in determining the market capitalization of firms. This finding supports the hypothesis that corporate governance adds value to companies and that investments in effective governance systems have a net positive benefit and should be pursued.

Exploring the ENSO modulation of the QBO periods with GISS E2.2 models
Authors: Zhou Tiehan , DallaSanta Kevin J. , Orbe Clara , Rind David H. , Jonas Jeffrey A. , Nazarenko Larissa , Schmidt Gavin A. , Russell Gary
Published: January 2024

Abstract. Observational studies have shown that the El Niño–Southern Oscillation (ENSO) exerts an influence on the Quasi-Biennial Oscillation (QBO). The downward propagation of the QBO tends to speed up and slow down during El Niño and La Niña, respectively. Recent results from general circulation models have indicated that the ENSO modulation of the QBO requires a relatively high horizontal resolution, and that it does not show up in the climate models with parameterized but temporally constant gravity wave sources. Here, we demonstrate that the NASA Goddard Institute for Space Studies (GISS) E2.2 models can capture the observed ENSO modulation of the QBO period with a horizontal resolution of 2∘ latitude by 2.5∘ longitude but with its gravity wave sources being parameterized interactively. This is because El Niño events lead to more vigorous gravity wave sources generating more absolute momentum fluxes over the equatorial belt, as well as less filtering of these waves into the tropical lower stratosphere through a weakening of the Walker circulation. Various components of the ENSO system, such as the sea surface temperatures, the convective activities, and the Walker circulation, are intimately involved in the generation and propagation of parameterized gravity waves, through which ENSO modulates the QBO period in GISS E2.2 models.
Drone CO2 Measurements During the Tajogaite Volcanic Eruption
Authors: Ericksen John , Fischer Tobias , Fricke G. Matthew , Nowicki Scott , Pérez Nemesio , Hernández Pérez Pedro , Padrón González Eleazar , Moses Melanie
Published: January 2024

Abstract. We report in-plume carbon dioxide (CO2) concentrations and isotope ratios during an active eruption of the Tajogaite Volcano. CO2 measurements inform our understanding of volcanic contributions to the global climate carbon cycle, and the role of CO2 in eruptions. Traditional ground-based methods of CO2 collection are difficult and dangerous, as a result only 5 % of volcanoes have been surveyed. We demonstrate that Unpiloted Aerial System (UAS) surveys allow for fast and relatively safe measurements. Using CO2 concentration profiles we estimate total flux to be 1.19 × 106 to 2.80 × 107 t day−1. Isotope ratios indicated a deep magmatic source, consistent with the intensity of the eruption. Our work demonstrates the feasibility of UASs for CO2 surveys during active volcanic eruptions, particularly in calculating plume characteristics.

Abstract. Science communication is an important part of research, including in the geosciences, as it can benefit society, science, and make science more publicly accountable. However, much of this work takes place in “shadowlands” that are neither fully seen nor understood. These shadowlands are spaces, aspects, and practices of science communication which are not clearly defined and may be harmful with respect to the science being communicated or for the science communicators themselves. With the increasing expectation in academia that researchers should participate in science communication, there is a need to address some of the major issues that lurk in these shadowlands. Here the editorial team of Geoscience Communication seeks to shine a light on the shadowlands of geoscience communication and suggest some solutions and examples of effective practice. The issues broadly fall under three categories: 1) harmful or unclear objectives; 2) poor quality and lack of rigor; and 3) exploitation of science communicators working within academia. Ameliorating these will require: 1) clarifying objectives and audiences; 2) adequately training science communicators; and 3) giving science communication equivalent recognition to other professional activities. By shining a light on the shadowlands of science communication in academia and proposing potential remedies, our aim is to cultivate a more transparent and responsible landscape for geoscience communication—a transformation that will ultimately benefit the progress of science, the welfare of scientists, and more broadly society at large.
Quantifying the potential of using SMAP soil moisture variability to predict subsurface water dynamics
Authors: Nayak Aruna Kumar , Xu Xiaoyong , Frey Steven K. , Khader Omar , Erler Andre R. , Lapen David R. , Russell Hazen A. J. , Sudicky Edward A.
Published: January 2024

Abstract. Advances in satellite Earth observation have opened up new opportunities for a global monitoring of soil moisture (SM) at fine to medium resolution, but satellite remote sensing can only measure the near-surface soil moisture (SSM). As such, it is critically important to examine the potential of satellite SSM measurements to derive the water resource variations in deeper subsurface. This study compares the SSM variability captured by the Soil Moisture Active and Passive (SMAP) satellite and the Soil Water Index (SWI) derived from SMAP SSM with subsurface SM and groundwater (GW) dynamics simulated by a high resolution fully-integrated surface water - groundwater model over an agriculturally-dominated watershed in eastern Canada across two spatial scales, namely SMAP product grid (9 km) and watershed (~4000 km2). SMAP measurements compare well with the hydrologic simulations in terms of SSM variability at both scales. Simulated subsurface SM and GW storage show lagged and smoother characteristics relative to SMAP SSM variability with an optimal delay of ~1 days for the 25‒50 cm SM, ~6 days for the 50‒100 cm SM, and ~11 days for the GW storage for both scales. Modelled subsurface SM dynamics agree well with the SWI derived from SMAP SSM using the classic characteristic time lengths (15 days for the 0‒25 cm layer and 20 days for the 0‒100 cm layer). The simulated GW storage showed a slightly delayed variation relative to the derived SWI. The quantified optimal characteristic time length Topt for SWI estimation (by matching the variations in SMAP-derived SWI and modeled root zone SM) is comparable to Topt obtained in other agricultural regions around the world. This work demonstrates SMAP SM measurements as a potentially useful aid when predicting root zone SM and GW dynamics and validating fully integrated hydrologic models across different spatial scales. This study also provides insights into the dynamics of near surface–subsurface water interaction and the capabilities and approaches of satellite-based SM monitoring and high resolution fully-integrated hydrologic modelling.
Perspectives on the misconception of levitating soil aggregates
Authors: Garland Gina , Koestel John , Johannes Alice , Heller Olivier , Doetterl Sebastian , Or Dani , Keller Thomas
Published: January 2024

Abstract. Soil aggregation is an important process in nearly all soils across the globe. Aggregates develop over time through a series of abiotic and biotic processes and interactions, including plant growth and decay, microbial activity, plant and microbial exudation, bioturbation, and physicochemical stabilization processes, and are greatly influenced by soil management practices. Together, and through feedback with organic matter and primary soil particles, these processes form dynamic soil aggregates and pore spaces, which jointly constitute a soil's structure and contribute to overall soil functioning. Nevertheless, the concept of soil aggregates is hotly debated, leading to confusion about their function or relevancy to soil processes. We argue here that the opposition to the concept of soil aggregation likely stems from the fact that the methods for the characterization of soil aggregates have largely been developed in the context of arable soils, where tillage promotes the formation of distinct soil aggregates that are easily visible in the topsoil. We propose that the widespread use of conceptual figures showing detached and isolated aggregates can be misleading and has contributed to the skepticism towards soil aggregates. However, the fact that we do not always see discrete aggregates within soils in situ does not mean that aggregates do not exist or are not relevant to the study of soil processes. Given that, by definition, soil aggregates consist of any group of soil particles that cohere more strongly to each other than neighboring particles, aggregates may, but do not necessarily need to be, bordered by pore space. Here, we illustrate how aggregates can form and dissipate within the context of undisturbed, intact soils, highlighting the point that aggregates do not necessarily need to have a discrete physical boundary and can exist seamlessly embedded in the soil. We hope that our contribution helps the debate on soil aggregates and supports the foundation of a shared understanding on the characterization and function of soil structure.
On the importance of the humidity flux for the surface mass balance in the accumulation zone of the Greenland Ice Sheet
Authors: Dietrich Laura J. , Steen-Larsen Hans Christian , Wahl Sonja , Faber Anne-Katrine , Fettweis Xavier
Published: January 2024

Abstract. It is highly uncertain how the humidity flux between the snow surface and the atmosphere contributes to the surface mass balance (SMB) of the interior Greenland Ice Sheet (GrIS). Due to sparse observations, evaluations of the simulated humidity flux are limited. Model-based estimates of the humidity flux contribution to the SMB are, therefore, unconstrained and even disagree in magnitude and sign. In this study, we evaluate the regional climate model MAR at the EGRIP (East Greenland Ice-Core Project) site in the accumulation zone of the GrIS. We use a combined dataset of continuous one-level bulk estimates of the humidity flux covering the period of May 2016–August 2019 and eddy-resolving eddy-covariance humidity flux measurements from all four summer seasons. In summer, we document a bias of too little sublimation (−1.3 W m−2, −1.65 mm w.e.) caused by a cold bias in both air and surface temperature, leading to a reduced humidity gradient. In winter, MAR overestimates vapor deposition by about 1 order of magnitude. This is a consequence of an overestimated temperature gradient in too stable atmospheric conditions compared to observations. Both systematic errors cause a large discrepancy in the annual net humidity flux between the model and observations of −9 mm w.e. yr−1. Remarkably, the simulated net annual humidity flux contributes positively to the SMB, contrary to observations documenting a net sublimation flux. We correct the systematic errors by applying a simple but effective correction function to the simulated latent heat flux. Using this correction, we find that 5.1 % of the annual mass gain at the EGRIP site sublimates again, and 4.3 % of the total mass gain is deposited vapor from the near-surface air. The estimated net humidity flux contribution to the annual SMB is about −1 % (net sublimation) compared to +5.6 % for the uncorrected simulation. In summer, the corrected MAR simulation shows that vapor deposition accounts for 9.6 % of the total mass gain and that 31 % of the total mass gain at the EGRIP site sublimates again. The net fluxes contribute to −32 % of the summer SMB. These results demonstrate that the humidity flux is a major driver of the summer SMB in the accumulation zone of the GrIS and highlight that even small changes could increase its importance for the annual SMB in a warming climate.
Non-proportionality analysis of multiaxial fatigue stress histories in trailing edge adhesive joints of wind turbine rotor blades
Authors: Balzani Claudio , Noever Castelos Pablo
Published: January 2024

Abstract. Wind turbine rotor blades are exposed to complex multiaxial stress states due to the aero-(hydro-)servo-elastic behaviour of the turbine. The dynamic response of rotor blades can result in non-proportional stress histories in the adhesive joints. These are not properly considered in current design guidelines and standards. However, knowledge about the degree of non-proportionality is crucial for choosing an appropriate fatigue analysis framework. This paper investigates the degree of non-proportionality of three-dimensional stress histories in trailing edge adhesive joints of wind turbine rotor blades. For the quantification of non-proportionality, the concept of so-called non-proportionality factors is utilized. Existing approaches show weaknesses for the application to adhesives. Hence, a novel non-proportionality factor is introduced in this work that combines two formulations from literature. After a concise verification, it is applied to analyze the trailing edge adhesive joints of three different blade designs in the framework of a numerical comparative study. The results do not reveal any correlation between the degree of non-proportionality and the blade size. General conclusions are hard to draw, as the blade response does not only depend on the turbine size, but also on the blade design philosophy. However, each blade shows significant degrees of non-proportionality that should not be neglected in fatigue damage analyses.
Developing a Research Design based on the distinction of History from the Social Sciences

Published: January 2024

The issues of methodology are mainly associated with the concept of authenticity and verification of knowledge which is a key element of epistemology. Since antiquity, various solutions have been proposed and methods were evolved in order to ensure accuracy and truthfulness of the knowledge gained. As far as history was concerned, its methods were evolved in its own epistemological framework in ancient and medieval times. However after the development of philosophy of science in the west, the discipline of history had to face severe methodological crisis. Some major philosophers of history after an evolutionary process rejected the methods of sciences; however the discipline is still somehow related with the social sciences. The present research argues that history is even different, ancient and unique from the social sciences. Thus the methods of research in history are entirely different and building a research design in history is a completely different task. The present research has evaluated the evolution of development of methods in the social sciences as well as in history in order to draw a distinction of social sciences from history. The study further proposed a historical research design which is based on the traditional methods of research in history; and which also ensures maximum authenticity by using tools of reliability. The study will help the historians to highlight the actual methodological nature of their discipline and to justify the claims of their researches as authentic and different from the rest of the social sciences at the same time.
The Rise of Militant Non-State Actors in the Middle East: Consequences for the Statehood
Authors: Dr. Syed Qandil Abbas  , Naqvi Syed Fraz Hussain
Published: January 2024

In the great power rivalries, the state employs various tactics to enforce their agenda at the regional scale. It involves conducting the intelligence based operations, limited strikes or fostering partnerships with the non-state actors. However, by forming the alliance with the non-state actors, the great powers often neglects the statehood of the parent state which results in the empowering of non-state actors. In the contemporary global order, militant non-state actors have generated a lot of attention owing to their increasingly transnational objectives. However, these non-state actors have also managed to evade the label of terrorism by integrating into the state structure of their parent states. In certain cases, where the integration was not feasible, the militant non-state actors have developed their social base through the incentives of social services. Under such circumstances, the state’s integrity is compromised which have led to the new debates of conceptualizing the role of militant non-state actors around the globe. This study would debate on these factors by limiting the focus in the Middle East and would highlight the sponsorship of foreign states in the rise of militant non-state actors.

Concerned Citizen: Narrativas Homonacionalistas en el Cine Queer
Authors: Vaz Magda
Published: January 2024

Partiendo de la idea de queer como ruptura y cuestionamiento de las normas de género y orientación sexual, es posible discernir una de las tensiones existentes entre el cine queer y el cine mainstream. La divergencia ocurre en la asimilación de sujetos de la comunidad LGBTIQA+ por parte del cine mainstream, incorporando personajes y tramas que se rigen y reproducen bajo lógicas y narrativas heteronormativas y occidentales. La película dirigida por Idan Haguel, Concerned Citizen, habita dicha tensión presentando una pareja gay israelí que vive en Tel Aviv en un barrio multicultural en proceso de gentrificación donde planean convertirse en padres. Teniendo en cuenta dicha tensión, se llevará a cabo un análisis tanto del contexto de producción así como de la significativa recepción y recorrido de festivales. Esto nos llevará a entender mejor el contexto sociopolítico en el que se inscribe la película y la función que desempeñan las instituciones cinematográficas dentro de este. A su vez, se utilizará una metodología híbrida entre el análisis hermenéutico y la semiótica visual, analizando desde los estudios culturales y de género la repetición de las estructuras narrativas y el desarrollo del protagonista. A través de dicho análisis se pretende llegar a la identificación del habitus homonormativo en la política y sus posibles brechas dentro de la película. A su vez, la evolución del Ben, el personaje principal, arrojará luz a la relación del binarismo víctima-opresor dentro de un contexto de homonacionalización.

Cine queer revisitado por la narrativa transmedia: el álbum visual Montero de Lil Nas X
Authors: Balbuena Morilla Ana , Sedeño-Valdellos Ana
Published: January 2024

El queer cinema y el black queer cinema han dejado su influencia en figuras, motivos, temáticas y modos de narrar que son de alguna manera reapropiados por ciertos textos visuales contemporáneos procedentes de las empresas de la industria mediática, como los videoclips. La transmedialidad es una herramienta de promoción para los artistas de música popular con objetivos comerciales y de generación de un universo, un mensaje de reivindicación y de cambio social con toda su obra. Este trabajo tiene como objetivo realizar un acercamiento al cine queer, en su vertiente black queer cinema, reflexionando sobre su legado en un proyecto transmedia y contemporáneo, el álbum visual del artista Lil Nas X, Montero, con quince videoclips. El planteamiento enfoca el disco como un proyecto de creación de storytelling, que construye una narrativa personal en torno a una serie de temáticas, figuras y motivos visuales recurrente que dibujan un mensaje general, fundan una personalidad artística. La metodología incluye el análisis textual y descriptivo de naturaleza cualitativa, de letras y imagen secuencial en movimiento, análisis iconográfico y en busca de elementos de continuidad y de citas a otras obras y a sus comentarios en redes sociales. Las conclusiones reafirman la transmedialidad e intertextualidad del álbum, analizan los leitmotivs visuales, objetos, tipos de figuración y simbología que permiten hablar de una continuidad narrativa visual y un discurso de empoderamiento y catarsis individual.
