MAR-YOLOv9: A multi-dataset object detection method for agricultural fields based on YOLOv9
Authors: Lu Dunlu , Wang Yangxu
Published: October 2024

With the development of deep learning technology, object detection has been widely applied in various fields. However, in cross-dataset object detection, conventional deep learning models often face performance degradation issues. This is particularly true in the agricultural field, where there is a multitude of crop types and a complex and variable environment. Existing technologies still face performance bottlenecks when dealing with diverse scenarios. To address these issues, this study proposes a lightweight, cross-dataset enhanced object detection method for the agricultural domain based on YOLOv9, named Multi-Adapt Recognition-YOLOv9 (MAR-YOLOv9). The traditional 32x downsampling Backbone network has been optimized, and a 16x downsampling Backbone network has been innovatively designed. A more streamlined and lightweight Main Neck structure has been introduced, along with innovative methods for feature extraction, up-sampling, and Concat connection. The hybrid connection strategy allows the model to flexibly utilize features from different levels. This solves the issues of increased training time and redundant weights caused by the detection neck and auxiliary branch structures in traditional YOLOv9, enabling MAR-YOLOv9 to maintain high performance while reducing the model’s computational complexity and improving detection speed, making it more suitable for real-time detection tasks. In comparative experiments on four plant datasets, MAR-YOLOv9 improved the mAP@0.5 accuracy by 39.18% compared to seven mainstream object detection algorithms, and by 1.28% compared to the YOLOv9 model. At the same time, the model size was reduced by 9.3%, and the number of model layers was decreased, reducing computational costs and storage requirements. Additionally, MAR-YOLOv9 demonstrated significant advantages in detecting complex agricultural images, providing an efficient, lightweight, and adaptable solution for object detection tasks in the agricultural field.

Published: October 2024

Background

Undernutrition is a significant challenge for adolescent girls globally due to biological, social, and cultural factors. The consequences of undernutrition for adolescent girls are extensive, impacting their cognitive abilities, reproductive health, susceptibility to chronic diseases in later life, and the economies of nations. However, there needs to be a more comprehensive understanding of the nutritional status of adolescent girls in the Diga district, Ethiopia.

Objective

This study aimed to assess the prevalence of undernutrition and its associated factors among adolescent girls in the Diga District, East Wollega Zone, Ethiopia.

Methods

The study employed a community-based cross-sectional study design in Diga District, Ethiopia. Data was gathered from 651 study participants using a systematic random sampling technique, from July 10th to August 10th, 2023. Data analysis involved using Epi-Data 4.6 and SPSS version 26 for data entry and statistical analysis, respectively. The Body Mass Index (BMI) and Height-for-age (HFA) Z-score are generated using WHO AnthroPlus version 1.0.4 software. Descriptive statistics and binary logistic regressions were used for data summarization and analysis, with significance testing at a p-value <0.05.

Results

In this study, 16.3% (95% CI: 13.5–19.3) of adolescent girls were stunted, while 18.5% (95% CI: 15.4–21.5) were thin. Lack of access to health and nutrition information (AOR = 3.36, 95% CI: 1.38–8.23), limited crop variety within household’s crops (AOR = 1.66, 95% CI: 1.03–2.65), and household food insecurity (AOR = 2.76, 95% CI: 1.49–5.11) were factors associated with stunting. Poor dietary diversity scores (AOR = 7.52, 95% 95% CI: 2.92–19.39) and household food insecurity (AOR = 3.69, 95% CI: 1.96–6.93) were significantly associated with thinness.

Conclusion

Conclusively, there was a low prevalence of stunting and thinness among adolescent girls in the Diga district, Ethiopia. Interventions aimed at enhancing household-level crop diversity, improving food security, providing adequate health and nutrition information, and promoting income-generating activities for adolescent girls can play a crucial role in improving their access to nutritious foods and healthcare, ultimately leading to better nutritional outcomes.
Defining the molecular response to ischemia-reperfusion injury and remote ischemic preconditioning in human kidney transplantation

Published: October 2024

Background

Ischemia-reperfusion injury (IRI) inevitably occurs during kidney transplantation and extended ischemia is associated with delayed graft function and poor outcomes. Remote ischemic preconditioning (RIPC) is a simple, noninvasive procedure aimed at reducing IRI and improving graft function. Experimental studies have implicated the kynurenine pathway as a protective mechanism behind RIPC.

Methods

First, paired biopsies from 11 living kidney donors were analyzed to characterize the acute transcriptomic response to IRI. Second, 16 living kidney donors were subjected to either RIPC (n = 9) or no pretreatment (n = 7) to evaluate the impact of RIPC on the transcriptomic response to IRI. Finally, the effect of RIPC on plasma metabolites was analyzed in 49 healthy subjects.

Results

There was a robust immediate response to IRI in the renal transcriptomes of living-donor kidney transplantation, including activation of the mitogen-activated protein kinase (MAPK) and epidermal growth factor receptor (EGFR) pathways. Preconditioning with RIPC did not significantly alter the transcriptomic response to IRI or the concentration of plasma metabolites.

Conclusions

The present data validate living-donor kidney transplantation as a suitable model for mechanistic studies of IRI in human kidneys. The failure of RIPC to alter transcriptomic responses or metabolites in the kynurenine pathway raises the question of the robustness of the standard procedure used to induce RIPC, and might explain the mixed results in clinical trials evaluating RIPC as a method to attenuate IRI.
Canine courtship: Zoomorphism in Japanese Boys Love Omegaverse manga
Authors: Sarracino Callum Hew
Published: October 2024

In 2010, in the English-language kink fanfiction community of the American television show Supernatural (2005–20), the Omegaverse genre emerged. In this universe, humans have canine-like sexual characteristics and society is structured around a sexual hierarchy stratified by whether one is an alpha, a beta or an omega. In the years since, the genre has spread globally, finding particular popularity in Japanese Boys Love (BL) media. The Omegaverse represents one part of a global boom in zoomorphism, the depiction of humans with animal-like characteristics, for representing and understanding human societal norms. Through a textual and discourse analysis of three Japanese Omegaverse BL manga series and associated reviews from BL fan site Chill Chill, this article discusses the appeal of zoomorphism, its boom in popularity and the reasons for its global spread. Drawing on animal studies, I highlight how the Omegaverse provides a space to critique and explore issues surrounding relationships in the real world, arguing that this suggests that the global appeal of zoomorphism is in how the animal can reflect what it means to be human.
How Much Land Does a Man Need?: Indian theatre as inspiration and Kathakali in performing Lev Tolstoy
Authors: Boldea Sorin-Dan
Published: October 2024

Indian theatre is currently studied at a theoretical level in Romanian academic theatre institutes, including both state and private universities. Particularly, one of the Indian theatre forms, Kathakali, is studied with an emphasis on the actor’s physicality in the play; however, the use of specific acting techniques from Kathakali is highly encouraged in the construction of new performances that the students create. Even if it is a highly coded form of theatre and difficult to understand if one does not have the required training, there are students who opt to use several performative elements of the theatre form in their productions to create a valuable intercultural dialogue with diverse cultural and artistic references. Throughout this article, I propose a concise analysis of how I elected to use some elements of the theatre form in the composition of a role within the university. The understanding of these cultural choices and how studying even theoretical forms of theatre or dance-theatre, even if they are conceptually distanced from us, can help us expand our creative area – an important matter for many European creators.
The masculinized feminine body: The body politics and the construction of female identity in Mohiniyattam
Authors: Mangalath Swetha
Published: October 2024

The article explores the sociocultural construction of aesthetic identities and the ways in which the dominant ideologies have perpetuated specific narratives of the development of Mohiniyattam. Drawing on Michel Foucault’s concept of ‘episteme’ and Judith Butler’s theory of gender performativity, the study examines the femininity embodied in Mohiniyattam and argues that the dance form has been a tool for patriarchal ideologies, transmitted through generations of dancers manifested in their performance practice. The analysis extends to the contemporary scope of Mohiniyattam, questioning the rigid notion of femininity that has defined the dance form through erotic expressions of the dancer and exploring how innovative choreographies and performative interpretations can challenge such norms. The study uses oral histories and case studies to present a multifaceted view of Mohiniyattam’s historical evolution as a dance form. The revival of Mohiniyattam at different times reflects the dominant epistemes, marked by an embedded male gaze on the female dancing body. The performers’ own initiatives reframed the concept of femininity and its portrayal by exploring the potential of the trained dancing body.
Unbecoming of a unified religion: A Foucauldian reading of Girish Karnad’s Tale-danda and the Lingayat plight
Authors: Nouman Abdullah , Sharma Vibha
Published: October 2024

Based on the theme of caste conflict in Girish Karnad’s play Tale-danda, this article aims to delineate how a sub-sect of a majoritarian (Hindu) community endeavoured to establish itself as a distinct religious group (Lingayatism), failed miserably in its mission, and how it is forced to ultimately merge itself into the larger community. The article will explore the reasons for its failure from the events of Karnad’s play Tale-danda, written against the backdrop of the actual events of the Lingayat Movement led by the poet–saint Basavanna in the twelfth-century CE Karnataka. In the play, Karnad depicts many instances of caste consciousness and caste conflicts among the characters. The main objective of the study will be to analyse these sites of conflict as depicted by Karnad in his play Tale-danda, in light of the French philosopher Michel Foucault’s concepts of power/knowledge and discourse. This article will also highlight how sometimes intra-caste conflicts are more prominent than inter-caste conflicts.

Based on the results obtained, neutralization strategies were developed, consisting of a list of activities aimed at reducing greenhouse gas emissions. Finally, the conclusions of this research are presented.
Research on the Constructed-Wetland/Regulation-Tank System at Pontificia Universidad Javeriana's Bogotá Campus
Authors: Torres Andres , Galarza-Molina Sandra , Lara-Borrero Jaime , Forero Javier
Published: October 2024

The stormwater harvesting (SWH) project at Pontificia Universidad Javeriana (Bogotá) began in 2007, initiated by the Water and Environmental Engineering research group (Ciencia e Ingeniería del Agua y el Ambiente), as part of PUJB's Environmental Management Plan and in collaboration with the University's Office of Physical Resources. This process included assessments of water supply and demand, rainwater quality, and financial and construction considerations. The system—a constructed wetland/regulation tank (CWRT)—collects rainwater runoff from the university's parking building (3,776 m²), the soccer field, and surrounding areas (14,816 m²). Beyond its hydrological performance, especially during periods of water scarcity, the system also functions as a full-scale laboratory to study biodiversity and ecological impacts in hydrological and hydraulic processes. The monitoring program, focused on changes in rainwater quantity and quality, has inspired several master's and doctoral research projects. These studies explore critical topics in urban hydrology, including stormwater harvesting, urban sediment management, real-time decision-making systems, and environmental and human health. This paper outlines the development of the stormwater harvesting system, shares the main findings from research projects, and discusses ongoing projects.

Landscape in change – place in uncertainty. A case study of detachment
Authors: Markuszewska Iwona
Published: October 2024

This paper discusses place-oriented values via actions against unwanted landscape changes reported by the community affected. The case study was based on a post-mining area in the city of Poznań (Poland), now functioning as a naturally valuable ecosystem. The relationships between landscape changes and the local community’s perception of these changes were studied. The results showed that a landscape transformation which is not accepted by the local community can stimulate a sense of loss, specifically, a feeling of detachment from the emotionally valued landscape. Based on this, a conceptual framework of detachment from a place was constructed. In this regard, the findings fill the gap in the case of experiences of solastalgia and topophobia. Different qualitative methods supported the analytical proceedings, such as content analysis, in-depth interviews, case study visits, community observation, field study and exploratory analysis.

Moving (the focus) from denial to dialogue: The recommended directions for communicating climate change to non-expert audiences based on the analysis of climate scientists’ communicative experiences
Authors: Mytych Jagoda
Published: October 2024

The article’s topic reflects climate scientists’ presence and communication in the public sphere, while the main focus is on the two ways a society may respond to the climate scientists’ communicative efforts: by denying the scientific messaging (climate change denial) and by engaging in relation-building communication (climate change dialogue). Those aspects were explored from the point of view of American and Polish climate scientists through the method of in-depth interviewing. According to the scientists, as the study results show, the most effective way to enhance science-society dialogue on climate change is to detangle from unproductive denial narratives and truly embrace the dialogic model of science communication by opening it to feedback, including honest societal scepticism.
In the past, winter was winter, and summer was summer: Climate change in the eyes of older adults from Poland
Authors: Budziszewska Magdalena
Published: October 2024

Older adults have a long-time perspective when it comes to the perception of changes in local climate and are uniquely vulnerable to these developments in terms of health. The discussed in-depth, qualitative study is based on interviews with people from the age group over 65 years (N = 10; five females), who live in different regions of Poland, concerning their views on climate change and its mitigation. Reflexive thematic analysis was used to create a map of their observations and attitudes. Results indicate the importance of perceiving climate change in specific and local categories as well as show frequent identification of this issue with traditional environmentalism focussed on pollution and littering. This foregrounds difficulties in understanding invisible greenhouse gases and how they work. In terms of mitigation, the study has revealed little faith in climate action undertaken by fellow citizens and the government, as well as a sense of limited agency, which is also disproportionally projected onto children and young adults. However, through everyday observations, older adults appear to be profoundly aware of how climate change impacts the environment. Contrary to stereotypes, they also declare high emotional engagement in this issue. Consequently, despite being overlooked with respect to this subject, older adults can play an important role in promoting climate awareness and climate-friendly policies.

Published: October 2024

Calcium homeostasis is correlated closely with the occurrence and development of various cancers. The role of calcium homeostasis in prostate cancer has remained unclear. The present study aimed to investigate the relationship between transmembrane and crimp-crimp domain 1 (TMCO1) and calreticulin (CALR) in the pathological characteristics of prostate cancer and the mechanism of action on prostate cancer metastasis. Effects of CALR recombinant protein and TMCO1 knockdown on prostate cancer cells were investigated using following methods: cell cloning, Transwell, wound scratch assay, JC-1 assay, Fluo-4 Assay, endoplasmic reticulum (ER) fluorescent probe, mitochondrial fluorescence probe, Western blot and Immunofluorescence. TMCO1 and CALR are overexpressed in prostate cancer and knockdown of TMCO1 significantly inhibited the invasion, migration and cell proliferation. Furthermore, knocking down TMCO1 modulated the intensity of ER probes and mitochondrial fluorescence probes, and affected the levels of intracellular calcium ion and mitochondrial membrane potential. In addition, CALR recombinant protein upregulated the expression of epithelial-mesenchymal transition marker, Vimentin, Conversely, knockout of TMCO1 significantly reduced the expression of CALR and Vimentin. Knockout of TMCO1 can reverse the effect of CALR recombinant protein, elucidating the pivotal roles of TMCO1 and CALR in the regulation of prostate cancer metastasis through modulation of calcium homeostasis.

At present, digital media art and environmental design industries are rising in various fields, making art design a popular major. In the era of artificial intelligence (AI), the establishment of public cloud Internet of things in universities and improving the security of design information will help the integration of digital media art and environmental art design, and improve the efficiency of digital media art and environmental design. This article first explains the principles and existing problems of virtual reality (VR) technology, digital media art, and environmental design, then uses AI algorithm to integrate digital media art and environmental design, and finally analyzes the impact of the integration of digital media art and environmental design based on VR technology. The results show that the satisfaction of the integration of digital media art and environmental design based on VR technology has increased by 8.77%. In addition, VR technology also improves the speed of integration of digital multimedia art and environmental design, as well as the added value and design quality of design works. In short, the use of VR technology can better promote the integration of digital multimedia art and environmental design.
Min-max theory for capillary surfaces
Authors: Li Chao , Zhou Xin , Zhu Jonathan J.
Published: October 2024

We develop a min-max theory for the construction of capillary surfaces in 3-manifolds with smooth boundary.
In particular, for a generic set of ambient metrics, we prove the existence of nontrivial, smooth, almost properly embedded surfaces with any given constant mean curvature 𝑐, and with smooth boundary contacting at any given constant angle 𝜃.
Moreover, if 𝑐 is nonzero and 𝜃 is not

π

\frac{\pi}{2}

, then our min-max solution always has multiplicity one.
We also establish a stable Bernstein theorem for minimal hypersurfaces with certain contact angles in higher dimensions.
Geometry at infinity of the space of Kähler potentials and asymptotic properties of filtrations
Authors: Finski Siarhei
Published: October 2024

The main goal of this article is to describe a relation between the asymptotic properties of filtrations on section rings and the geometry at infinity of the space of Kähler potentials.
More precisely, for a polarized projective manifold and an ample test configuration, Phong and Sturm associated a geodesic ray of plurisubharmonic metrics on the polarizing line bundle.
On the other hand, for the same data, Witt Nyström associated a filtration on the section ring of the polarized manifold.
In this article, we establish a folklore conjecture that the pluripotential chordal distance between the geodesic rays associated with two ample test configurations coincides with the spectral distance between the associated filtrations on the section ring.
This gives an algebraic description of the boundary at infinity of the space of positive metrics, viewed – as it is usually done for spaces of negative curvature – through geodesic rays.

Published: October 2024

Artificial Intelligence (AI) is transforming different aspects of the economy and society of countries. There are diverse effects when comparing the impact in developed versus developing countries. In the educational sector, efforts to incorporate AI have largely ignored the input from those directly impacted by it. This document presents results from a survey about AI to university students in Latin America. The information presented comes from a survey conducted in November 2023 to college students with ages between 18 and 25 years in four Latin American countries: Mexico, Argentina, Peru, and Ecuador. The results indicate that, in general, youth have a positive view about the potential of AI, though limited knowledge in the topic. Moreover, university students in the region do not want to be passive recipients of AI. They want to participate directly in conversations about this very current topic and have concerns about different aspects of AI implementation in the region. These findings highlight the need for universities, governments, civil society and international organizations and the private sector to work together to create spaces for inclusive dialogue where the youth could directly participate in conversations that crucially matter for their lives.

Convergence analysis of non-matching finite elements for a linear monotone additive Schwarz scheme for semi-linear elliptic problems
Authors: Al Farei Qais , Boulbrachene Messaoud
Published: October 2024

In this article, we are interested in the standard finite element approximation method of linear additive Schwarz iterations for a class of semi-linear elliptic problems, for two subdomains, in the context of non-matching grids. More precisely, by means of a uniform convergence result from the study by Lui and a fundamental lemma consisting of estimating, at each iteration, the gap between the continuous and the finite element Schwarz iterates, we prove that the discrete Schwarz sequences converge, in the maximum norm, to the true solution. Moreover, we also give numerical results to support the theoretical findings.
Raging Ennui: On Boredom, History, and the Collapse of Liberal Time
Authors: Dikovich Albert
Published: October 2024

This article aims to outline a theory of political boredom based on the concept of theliberal temporal dispositive. According to this concept, modern politics is characterized by the reduction of political time consumption to enable the growing temporal autonomy of the individual. However, individuals may experience considerable stress in their pursuit to utilize this free time effectively. Boredom arises when individuals fail to “fill” their available time with meaningful actions. Political crises of boredom occur as attempts by individuals to relieve the pressures accompanying temporal autonomy, sometimes restarting political temporality on a new, massive scale. Furthermore, the article examines modern political philosophy as inherently rooted in the liberal temporal dispositive. Through several historical examples, it is discussed how political philosophy may either contribute to imbuing politics with a desire for meaning or abstain from it in an attitude of serene resignation. It is proposed that liberal democracy requires a temporal ethics based on the latter.

Függetlenségük elnyerését követően a nagyhatalmak nem fordítottak különösebb figyelmet a közép-ázsiai térségre, a régió országai tulajdonképpen külső befolyásoktól mentesen kezdték államukat és nemzetüket építeni. Napjaink Közép-Ázsiájának egyik legfontosabb jellemzője a változás; a régió országai komoly átalakuláson mennek keresztül. A világpolitika és -gazdaság változásai közepette a közép-ázsiai országokban erős a fejlődés, a modernizáció és a konnektivitás iránti vágy. Az összes nagy- és középhatalom aktív Közép-Ázsiában, köztük Kína, Oroszország, az Egyesült Államok, Európa, de Törökország és India is. Geopolitikai és stratégiai befolyás tekintetében kétségtelenül Kína, Oroszország és az Egyesült Államok tekinthető a legfontosabbnak. A nagyhatalmak közötti kapcsolatok bonyolult jellege által is inspirálva, külpolitikai téren a többvektorú diplomácia a közép-ázsiai országok közös jellemzője. A Kína, az Egyesült Államok, Oroszország és Európa közötti feszültségek ellenére a közép-ázsiai országok mindegyikükkel stratégiai partnerséget vagy stratégiai együttműködést alakítottak ki. A pragmatizmus a közép-ázsiai államok diplomáciájának is fontos jellemzője, amely azon az elven alapul, hogy valódi hasznot tudjanak realizálni az országuk számára.
Old cities, new pathways: approaches to Roman urbanism in Italy
Authors: Hoffelinck Adeline
Published: October 2024

Throughout the twentieth century, considerable research has been dedicated to understanding the rise, development and end of ancient cities. In recent years, there has been a remarkable upsurge of new methodological and theoretical approaches applied in urbanism studies, which enables us to improve, validate or question our knowledge about ancient urban life. The three books reviewed here concern the development, transformation and experience of ancient Roman cities; leading experts in urban history and archaeology discussing the potential of new technologies and conceptual frameworks for analysing Roman urban space.

Neonatal hypoxia (Hx) causes white matter (WM) injury, particularly in the cerebellum. We previously demonstrated that Hx-induced reduction of cerebellar Purkinje cell (PC) activity results in locomotor deficits. Yet, the mechanism of Hx-induced cerebellar WM injury and associated locomotor abnormalities remains undetermined. Here, we show that the cerebellar WM injury and linked locomotor deficits are driven by PC activity and are reversed when PC activity is restored. Using optogenetics and multielectrode array recordings, we manipulated PC activity and captured the resulting cellular responses in WM oligodendrocyte precursor cells and GABAergic interneurons. To emulate the effects of Hx, we used light-activated halorhodopsin targeted specifically to the PC layer of normal mice. Suppression of PC firing activity at P13 and P21 phenocopied the locomotor deficits observed in Hx. Moreover, histopathologic analysis of the developing cerebellar WM following PC inhibition (P21) revealed a corresponding reduction in oligodendrocyte maturation and myelination, akin to our findings in Hx mice. Conversely, PC stimulation restored PC activity, promoted oligodendrocyte maturation, and enhanced myelination, resulting in reversed Hx-induced locomotor deficits. Our findings highlight the crucial role of PC activity in cerebellar WM development and locomotor performance following neonatal injury.
Four Self-Replications to Assess the Robustness of Recent Lab Findings: Replications of Studies From Cheek and Ward (2019), Cheek, Schwartz, and Shafir (2023), Cheek and Murray (2023), and Cheek (2023)
Authors: Cheek Nathan , Yao Ziqi
Published: October 2024

This paper reports four preregistered replications (total N = 2,008) of previously published studies from our lab. The first study replicates Cheek and Ward (2019) Study 3, which found that people want more options when adopting a maximizing goal of making the best possible choice compared to a satisficing goal of making a “good enough” choice. The second study replicates Cheek, Schwartz, and Shafir (2023) Study 2, which found that larger choice sets make choices feel more self-expressive even when they do not afford better preference matching. The third study replicates Cheek and Murray (2023) Supplemental Study 5, which found that people’s intuitions about adaptation to psychophysical experiences are associated with their intuitions about adaptation to life hardship. The final study replicates Cheek (2023) Study 4, which found that an informational intervention can reduce the biased belief that individuals in poverty are less vulnerable to harm than higher-income individuals. We successfully replicated all of the original effects, increasing confidence in the earlier findings.
Una historia conceptual de los desastres. El conocimiento metafórico como posibilidad en la gestión del riesgo de inundaciones en El Valle La Estrella, Limón, Costa Rica
Authors: Coto-Cedeño Wainer Ignacio , Centeno-Morales Jacqueline
Published: October 2024

This article has got two objectives. The first analyzes, from history perspective, the experiences of population's El Valle La Estrella and their relationship with floods, territory and the Comité Comunal de Emergencias de El Valle La Estrella [CCEVE]. The second analyzes the member experiences of disaster risk management. The investigation was built based on interdisciplinary strategy; said strategy connected methods and techniques of anthropology, sociology, linguistics, and history. Specifically, the investigation used to oral history, ethnography, pragmatics, speech analysis and content analysis. Also, it was used to interviews to collect testimonials. The main conclusion is that metaphorical knowledge shows an unfinished hydro-social cycle where citizen and territorial management acts as a trigger for social disputes
Julià Nofre y la escultura del gótico internacional florentino en la Corona de Aragón
Authors: Valero Molina Joan
Published: October 2024

Entre los años 1418 y 1424, un escultor florentino trabaja en los relieves del trascoro de la catedral de Valencia. Este escultor, mencionado por la documentación como "Julià Florentí", ha sido tradicionalmente identificado con Giuliano di Giovanni da Poggibonsi, discípulo de Ghiberti. Unos años después, entre 1431 y 1434, otro escultor florentino, Julià Nofre, realiza ciertos trabajos en la catedral de Barcelona. La confrontación estilística de las obras valencianas y barcelonesas permitirá proponer la hipótesis sobre la identificación de Julià Florentí valenciano con Julià Nofre.
La adopción literaria del "nuevo cine español"
Authors: Bravo Laura
Published: October 2024

Las adaptaciones literarias que realizan los directores del Nuevo Cine Español de los años 60, que se presentaba como un movimiento joven y renovador, reflejan una vista atrás hacia obras neorrealistas de los 50 y hacia consagradas figuras de la "Generación del 98". Sin embargo, estas adaptaciones, que pretendían adecuarse a la política de ayudas del Régimen franquista para el cine a través del prestigio literario, consiguen trasladar sibilinamente obras de concretas referencias históricas en nítidos retratos de las condiciones sociales y culturales que se vivían en la década de los 60.Por otro lado, contra la línea tradicional que sigue esta rama del Nuevo Cine, la de la Escuela de Barcelona, representada por Gonzalo Suárez escritor o director de sus adaptaciones, va a mostrar un cine de carácter más innovador, casi revolucionario, aunque menos apoyado políticamente y sin el respaldo del público.
La planta centralizada en la Castilla bajomedieval: Entre la tradición martirial y la qubba islámica. Un nuevo capítulo de particularismo hispano
Authors: Ruiz Souza Juan Carlos
Published: October 2024

En este artículo estudiamos la pervivencia de la arquitectura de planta centralizada en la Corona de Castilla durante la Baja Edad Media. Ello constituye un capítulo singular dentro de la arquitectura medieval hispana, el cual puede explicarse gracias a la influencia que ejerció la arquitectura andalusí, donde la construcción de edificios centralizados fue una constante. El estudio de estas circunstancias unido a la llegada de nuevos lenguajes constructivos procedentes del gótico final europeo, explica la excepcionalidad de algunos edificios hispanos, sin ejemplos comparables en el Continente, de los siglos XIV-XVI.
El cuerpo muerto del rey Juan II, Gil de Siloé, y la imaginación escatológica. (Observaciones sobre el lenguaje de la escultura en la alta Edad Moderna)
Authors: Pereda Espeso Felipe
Published: October 2024

El sepulcro de los padres de la Reina Isabel la Católica en la Cartuja de Miraflores (Burgos) es una de las empresas artísticas en las que la implicación personal de la reina fue más profunda. Su original tipología en forma de estrella, y su imaginería andrófaga, son analizadas en este artículo en el contexto de la escatología escolástica, de acuerdo a dos argumentos complementarios. En primer lugar, la importancia que en la presentación de la resurrección de la carne tuvo la "metáfora de la escultura". En segundo lugar, la representación de los cuerpos celestes de los resucitados en el imaginario de este periodo. Sobre esta base, la peculiar solución de Gil de Siloé aparece como una personal aportación a la relación cuerpo-escultura del arte funerario, así como a la forma de experimentarlo.
Los triunfos andaluces: Un singular de la escultura barroca española
Authors: Novero Plaza Raquel
Published: October 2024

El presente artículo se centra en el estudio sistemático de los Triunfos como obras singulares de la escultura andaluza en el barroco español. Sin embargo, estos monumentos no son exclusivos de España sino que podemos encontrar diversos ejemplos en Nápoles, Viena y Munich. Los Triunfos se advocan principalmente a la Inmaculada Concepción, a San Rafael o al santo al que se tiene devoción en la ciudad.
Paragone entre pintura y escultura en el siglo XIX español
Authors: Reyero Carlos
Published: October 2024

El "Paragone" entre pintura y escultura, en la España del siglo XIX, nos permite conocer como la escultura fue considerada en desventaja como expresión artística, especialmente en lo que se refiere dos funciones principales del arte en ese siglo; persuadir y narrar. Este trabajo presenta opiniones contemporáneas de este problema, que afectó muy de cerca de los críticos de arte.
El debate sobre la imagen en la España del siglo XV: judíos, cristianos y conversos

Published: October 2024

Este artículo analiza la polémica de la imagen religiosa en la España del siglo XV y edita dos textos fundamentales para su reconstrucción: sendos capítulos apologéticos de las obras del fray Alonso de Espina y del converso Pablo de Santa María, los cuales demuestran la ausencia de un criterio homogéneo en un momento en el que las imágenes jugaron un papel importante en el enfrentamiento religioso.

"Obras... que hazer para entretenerse". La arquitectura en la cultura nobiliario-cortesana del Siglo de Oro: a propósito del marqués de Velada y Francisco de Mora
Authors: Martínez Hernández Santiago
Published: October 2024

El propósito de este artículo es ofrecer un primer acercamiento a la significación alcanzada por la arquitectura como parte esencial de los usos culturales de la nobleza cortesana española durante los siglos XVI y XVII. El ejemplo que representa el marqués de Velada como caballero virtuoso, que se relaciona con arquitectos como Francisco de Mora y se interesa e interviene en los proyectos que patrocina, permite conocer el valor que esa nobleza otorgó a la práctica arquitectónica. Parte destacada de la aristocracia cortesana incluyó la arquitectura y otros estudios de ciencias dentro de su propio aprendizaje caballeresco haciendo de estos saberes un elemento indispensable de su formación como futuros servidores de la Monarquía Hispánica, al tiempo que los asumieron como aficiones en las que entretenían su valioso tiempo.
