Bonding as a spatial practice: Bonding through drawing
Authors: Avanoğlu İpek
Published: December 2024

Based on a personal bonding experience I had with a roof beam during a temporary residency in Brussels, I look into possibilities of bonding as a practice through drawing. Bonding with a roof beam describes a particular process through which I gradually meet the surroundings in tactile proximities. I discuss that this process suggests an interplay between emotive and material aspects of bonding. Evolving through a series of experiments of drawing and three-dimensional studies, this paper presents three sets of works: the drawing of the roof beam reveals a corporeal presence, preparatory bonding and drawing of the preparatory bonding no 1. These works elaborate on this interplay by seeking embodied relations between materials, tools and techniques of drawing with regard to tactile proximities, suggesting embodied spatio-temporalities and in-between spaces. I discuss that each individual work reconfigures the space of the drawing, as well as the experience of drawing, engaging in a discussion on matter, materiality and corporeality. Through the experiments, I argue that this drawing practice offers a liminal space of possibilities within the artefactual works by which a drafter finds a way to approach space by desire for an embodied materiality. In relation, I suggest that the bonding process becomes tactical in a state of transience as it offers ways to relate oneself to a place by desire.
Energiapiaci trendek a közelmúltbeli események tükrében

Az Európai Unió (EU) az energiaátmenet felé irányuló
törekvését ambiciózus kezdeményezésekkel kívánja elősegíteni,
amelyek célja a megújuló energiaforrásokra való fokozott
támaszkodás növelése, a klímaváltozás kezelése és a tiszta energia
előállításának támogatása. Ugyanakkor, a megújuló energiaforrások,
például a szél- és napenergia integrálása az energiamixbe
átalakítja a piaci dinamikákat. E tanulmány célja az elmúlt
évtized nagykereskedelmi villamosenergia-árak alakulásának és a
megújuló energiák trendjeinek bemutatása, a nagykereskedelmi
villamosenergia-piac áttekintése és a villamosenergia-árakat
befolyásoló kulcsfontosságú tényezők beazonosítása. Az EU
villamosenergia-piacain ún. merit order mechanizmus működik, ahol
az erőművek által termelt források igénybevétele a határköltségek
növekvő sorrendje alapján történik. Ezt a mechanizmust jelentősen
befolyásolja az alacsony határköltségű megújuló energia növekvő
aránya, ami potenciálisan csökkentheti a nagykereskedelmi
villamosenergia-árakat. Azonban a megújuló energiaforrások,
melyeknek termelési hatékonysága nagyban függ az időjárási
körülményektől volatilitást is eredményeznek, ami rugalmasan
kezelhető tartalék kapacitás kiépítését teszi szükségessé. Ezt
gyakran gáztüzelésű erőművek szolgáltatják, amely viszont
befolyásolja a gázkeresletet és -árat is. A 2020-as évek eleje,
amelyet világjárvány és háború jellemzett, szemlélteti az ilyen
jellegű válságoknak az energiapiacokra gyakorolt mélyreható
hatásait, kiemelve a globális energiarendszerek egymástól való
függőségét és az EU gázimporttal kapcsolatos sebezhetőségét, az
áringadozások pedig mind a piaci stabilitásra, mind a fogyasztói
megfizethetőségre nézve kihívásokat generálnak. Ilyen válságokkal
teli időkben az energiatrilemma problémaköre – azaz a
fenntarthatóság, a megfizethetőség és az ellátásbiztonság közötti
egyensúly megteremtése – egyre nehezebben megoldhatóvá válik.
Annak ellenére, hogy ez az energiaátmenet egy összetett folyamat,
elengedhetetlen a bolygónk és a jövő generációk jólétének
megőrzése érdekében.

Management of patients with cognitive impairment in old age
Authors: Grishina D. A. , Lokshina A. B. , Sokolov E. A.
Published: December 2024

Cognitive impairment (CI) is one of the most common disorders in elderly. As the population ages, the prevalence of cognitive impairment CI is also increasing. The importance of early identification of individuals with mild CI (MCI) lies in the fact that timely diagnosis of these disorders increases the potential for secondary prevention and therapeutic intervention, which can delay or even prevent the onset of occupational and social maladaptation due to the development of dementia. The current principles of classification of the MCI and the criteria for its diagnosis are presented. Current approaches to the treatment of patients with CI are discussed. It is shown that treatment should start as early as possible and include both non-pharmacological and pharmacological approaches to improve cognitive abilities and prevent CI progression. The possibilities of modern neuroprotective and symptomatic therapy of MCI and the role of choline alfoscerate in the treatment of MCI and dementia are presented. The results of the multicenter placebo-controlled ASCOMALVA study are discussed, in which the addition of choline alfoscerate to donepezil therapy in patients with Alzheimer's disease and cerebrovascular disease helped to slow the progression of CI, reduce the severity of the disease, and had a positive effect on the behavioral functions and emotional status of both patients and their caregivers. In addition, a decrease in the progression of cerebral atrophy was observed. A new form of choline alfoscerate (Cerpechol) for oral administration is reported that may increase patients' compliance and can be used in patients with dysphagia.

Cerebral small vessel disease (CSVD) associated with age and vascular risk factors has a high prevalence and social significance. Psychoemotional changes are an early manifestation of CSVD that require methods for their correction. Objective: to evaluate and compare the efficacy of biofeedback (BF) at infra-low frequencies and alpha waves frequencies in correcting emotional changes in patients with early CSVD. Material and methods. The study included 71 patients (85% women; mean age 52.8±6.3 years) with early CSVD and 21 healthy volunteers (71% women; mean age 53.2±4.8 years). Patients were randomized into three groups using the envelope method with double-blind placebo control: BF-neurotraining at infra-low frequencies (n=25), alpha waves (n=22) and imitation of BF based on electroencephalography parameters (placebo; n=24). Fifteen 30-minute individual sessions were conducted 2–5 times per week. Clinical symptoms, brain MRI data and psychoemotional status were assessed in all participants before and immediately after the BF course and 6–8 weeks later. Results. Patients with early-stage CSVD were characterized by an medium level of situational and a high level of personal anxiety, mild symptoms of depression and an medium level of alexithymia. Infra-low frequencies and alpha waves BF-neurotrainings were comparable in terms of their efficacy in reducing personal anxiety. Alpha waves training also showed an effect in reducing situational anxiety in the long term. Infralow frequencies training also reduced the level of depression. Placebo training had no effect on the parameters studied. Conclusion. In patients with early CSVD, BF-neurotraining at infra-low frequencies and alpha waves may be one of the methods for correcting the emotional changes associated with CSVD.

Authors: Grishina D. A. , Starchina Yu. A. , Sokolov E. A. , Parfenov V. A.
Published: December 2024

Chronic cerebrovascular diseases (CVD) and neurodegenerative diseases (NDD) are the most common causes of cognitive impairment (CI). The development of dementia is preceded by mild CI (MCI) over several years.

Objective: to investigat the effect of inhaled nitric oxide therapy on cognitive function (CF) in patients with MCI due to CVD and NDD.

Material and methods. The study included 94 patients (25 men and 69 women aged 50 to 76 years, mean age 65.3±8.9 years) with MCI due to CVD and/or NDD of the brain. The patients were randomized into two groups: the main group (therapy) and the control group. The control group comprised 22 patients with MCI (5 men and 17 women aged 50 to 76 years, mean age 62.3±8.5 years) who received standard therapy (antihypertensive, antithrombotic and other agents). The main group comprised 72 patients (20 men and 52 women aged 50 to 76 years, mean age 66.2±8.0 years) who additionally inhaled a nitric oxide-enriched air mixture for 30 minutes daily using the Tianox device. Each patient had from 7 to 10 inhalation sessions (the first trial session lasted 20 minutes, the following sessions 30 minutes). Neuropsychological tests, emotional state and sleep quality were examined at the beginning and 3 and 6 months after the end of treatment. Results. In the main group, after 3 and 6 months, a significant (p<0.05) improvement in CF was found according the Montreal Cognitive Assessment (MoCA-test), Frontal Assessment Battery, the Digit Forward and Backward Span Test, the Digit Symbol Substitution Test, the Munsterberg Test, the Literal Association Test and the 12-word Delayed Free Recall Test. A significant (p<0.05) decrease in anxiety and depression according to the Hospital Anxiety and Depression Scale, the Beck Depression Inventory and the Spielberger Anxiety Scale as well as an improvement in sleep quality according to the Insomnia Severity Index were also observed. The therapy was well tolerated, and no serious adverse events occurred. No significant improvement in CF, emotional state or sleep was observed in the control group.

Conclusion. Brief therapy (7–10 sessions) with inhaled nitric oxide improves the CF and emotional state of patients with MCI on a background of CVD and NDD. Further studies on inhaled nitric oxide therapy in patients with MCI in a multicenter randomized trial with sham treatment are needed.

Regulation of blood nitric oxide (NO) levels is an essential component of maintaining cerebrovascular and cardiovascular blood flow. The production of NO in the vascular endothelium is influenced by numerous factors, including the supply of macro- and micronutrients. This article presents the results of systematization of data on the relationship between NO metabolism and nutrient factors. Particular attention is paid to the effect of group B vitamins (folates, vitamins B1, B2, B7 and B12) and the microbiome on vascular endothelial function, NO synthase activity and the prevention of oxidative-nitrosative stress. The correction of deficiencies in these vitamins (group B, A, C, E, D3), magnesium and calcium is an important part of the prevention of stress and a variety of diseases of the nervous system associated with endothelial dysfunction.

CD8+ T-Cell Signatures as Prognostic and Immunotherapy Response Predictors in Non-Small Cell Lung Cancer
Authors: Zhao Tienan , Dhillon Sarinder Kaur
Published: December 2024

Non-small cell lung carcinoma (NSCLC) represents the majority of lung cancer cases, comprising approximately 85 % of the total. The five-year survival rate for NSCLC patients remains discouragingly low. Recently, immunotherapy has emerged as a promising approach. Nevertheless, only a minority of patients experience considerable benefits from these treatments. This highlights the critical need for effective biomarkers that can predict both patient prognosis and response to immunotherapy. CD8+ T cells play a crucial role in cancer immunotherapy. Their presence within tumours is generally indicative of a favourable prognosis and increased efficacy of immunotherapy. This study was undertaken to identify and authenticate a novel biomarker signature based on CD8+ T-cell marker genes, to prognosticate therapeutic responses in individuals afflicted with NSCLC. This in-depth study was based on a total of 1,200 samples, which included four NSCLC specimens analysed through single-cell RNA sequencing (scRNA-seq), 1,000 NSCLC samples obtained from The Cancer Genome Atlas (TCGA) and 196 NSCLC specimens collected from the GSE37745 cohort. In patients with NSCLC, those presenting a favourable risk profile demonstrated notable elevations in specific immune cells while concurrently exhibiting reductions in other types. CD8+ T cells, with their established role in inducing apoptosis in cancer cells, have emerged as crucial predictors and modulators of treatment strategies for NSCLC patients. The combination of single-cell and bulk RNA sequencing has produced a biomarker signature, emphasizing the CD8+ T cells’ crucial role in NSCLC prognosis and treatment.
La inteligencia artificial generativa en la música y el derecho de autor colombiano

Published: December 2024

Por primera vez en la literatura, a través de una investigación de corte cualitativo y documental con aplicación de un método sistemático e inductivo, el presente artículo aborda la interacción del derecho de autor colombiano y los derechos conexos a las nuevas realidades que trae la inteligencia artificial (IA) generativa al sector de la música, tales como la generación autónoma de obras musicales, interpretaciones y fonogramas, al igual que la imitación de estilos musicales y de voces de cantantes. El presente artículo concluye que, bajo la normativa autoral colombiana, (1) las obras musicales generadas en un 100 % por inteligencia artificial no tienen un autor protegido y que las interpretaciones creadas por IA no están protegidas por los derechos conexos; no obstante, los fonogramas generados por IA sí podrían obtener protección; (2) realizar obras por medio de un algoritmo de IA con base en obras existentes, por medio de un proceso de minería de datos, no constituirá una infracción siempre y cuando se realice dentro de los supuestos de la excepción de domicilio privado y copias temporales; (3) finalmente, la imitación de estilos y de voces de artistas por parte de la IA no es de protección del derecho de autor o de los derechos conexos. Sin embargo, al tratarse de una tecnología de rápida y constante evolución, requiere de un seguimiento y adaptación constantes por parte del derecho de autor.

Głównym celem niniejszego artykułu jest przeanalizowanie stosunków Armenii, Azerbejdżanu oraz Gruzji z Izraelem w kontekście ataku Hamasu z 7 października 2023 r. Mimo iż Armenia, Azerbejdżan oraz Gruzja nie są zaliczane do regionu Bliskiego Wschodu (a do tzw. obszaru byłego ZSRR), to jednak bardzo uważnie obserwują procesy zachodzące na sąsiadującym obszarze. Zbadanie postawy trzech państw zakaukaskich wynika z chęci poszukania odpowiedzi na pytanie, czy władze wszystkich trzech wymienionych wyżej krajów podobnie zareagowały na kolejne rozmrożenie konfliktu izraelsko-palestyńskiego, czy może jednak występowały w tym zakresie pewne różnice. Pozwoli to określić, jak współcześnie wyglądają relacje pomiędzy Izraelem a Armenią, Azerbejdżanem oraz Gruzją, a także to, czy którąś z republik Kaukazu Południowego można nazwać lojalnym sojusznikiem Izraela w tym regionie.

Authors: Akhtar Md. Amir Khusru , Kumar Mohit , Verma Sahil , Cengiz Korhan , Verma Pawan Kumar , Khurma Ruba Abu , Alazab Moutaz
Published: December 2024

The electromagnetic-gravity optimization (EMGO) framework is a novel optimization technique that integrates the fine-structure constant and leverages electromagnetism and gravity principles to achieve efficient and robust optimization solutions. Through comprehensive performance evaluation and comparative analyses against state-of-the-art optimization techniques, EMGO demonstrates superior convergence speed and solution quality. Its unique balance between exploration and exploitation, enabled by the interplay of electromagnetic and gravity forces, makes it a powerful tool for finding optimal or near-optimal solutions in complex problem landscapes. The research contributes by introducing EMGO as a promising optimization approach with diverse applications in engineering, decision support systems, machine learning, data mining, and financial optimization. EMGO’s potential to revolutionize optimization methodologies, handle real-world problems effectively, and balance global exploration and local exploitation establishes its significance. Future research opportunities include exploring adaptive mechanisms, hybrid approaches, handling high-dimensional problems, and integrating machine learning techniques to enhance its capabilities further. EMGO gives a novel approach to optimization, and its efficacy, advantages, and potential for extensive adoption open new paths for advancing optimization in many scientific, engineering, and real-world domains.
Effects of chemical environment on softwood kraft pulp: exploring beyond conventional washing methods
Authors: Senthilkumar Eashwara Raju , Henriksson Gunnar , Lindström Mikael E. , Vikström Tomas , Sevastyanova Olena
Published: December 2024

Brownstock washing, a critical process in cleansing kraft pulp, removes dissolved lignin residues from the pulp after it has passed through the cooking digester. It plays a significant role in kraft pulp mills by enhancing economic efficiency and environmental sustainability. Improved washing efficiency leads to better pulp quality and more effective recovery of cooking chemicals. Our study aimed to better understand the impact of different chemical compositions in washing liquors on washing performance. We tested a range of washing liquors, including neutral solutions (deionized water, 1M NaCl, 3M NaCl, 1M Na2SO4) and alkaline solutions (tap water, washing liquor composed of 0.35M NaOH and 1M Na2SO4, and white liquor with 50 g[OH]/l and 8.77 g[HS]/l). These liquors were evaluated for their efficacy in maximizing lignin extraction. Our findings suggest that salt solutions generally reduce washing efficiency. Deionized water and white liquor proved to be the most efficient washing agents, while high-concentration salts and those with high ionic strength negatively impacted washing efficiency. This suggests that brownstock washing may not be operating at its full potential.

Kraft lignin has high dispersity and low reactivity. This study aimed to obtain more homogeneous and modified chemical fractions from the application of fractionation methods using organic solvents and acid precipitation. Organic solvents used were ethyl acetate, ethanol, methanol and acetone. The pHs tested were 9, 7, 5, 3 and 1, by adding hydrochloric acid. The fractions were characterized of acid-soluble and insoluble lignin, carbohydrates, ashes, elemental analysis and by Py-GC/MS. All fractions obtained in both fractionation methods showed higher carbon contents, higher purity and lower S/G ratio than the corresponding initial materials, characteristics that are very favorable for the application in biorefinery. Acetone-soluble (sequential) and pH 1 (one-step) precipitated fractions are the most promising for carbon fiber production. Fractions soluble in ethyl acetate (one-step) and insoluble at pH 3 and 1 (sequential) appear to be the most appropriate for applications that require good oxidative properties. The fractions soluble in ethanol (one-step), methanol (one-step), acetone (one-step) and precipitated at pH 9 (one-step) and pH 5 (sequential) are the ones that allow better chemical substitution in obtaining bioproducts. Fractions soluble in ethanol (sequential) and precipitated at pHs 5 and 1 (sequential) are not of commercial interest due to their low yield.
Experimental and numerical investigations on the mechanical properties of overmolded hybrid fiber reinforced thermoplastic composites
Authors: Tan Pingyang , Zhai Zhanyu , Liu Ningfeng , Shi Wuping
Published: December 2024

In this work, an anti-collision beam was manufactured through a thermoplastic composite overmolding (TCO) process. This process includes thermoforming of continuous glass fiber reinforced thermoplastic composite (CGFR-PP) and overmolding of short glass fiber reinforced thermoplastic composite (SGFR-PP). Double cantilever beam (DCB) and end-notched flexure (ENF) tests were performed to obtain the interfacial bonding fracture toughness between CGFR-PP and SGFR-PP, which was then used to establish a cohesive zone model (CZM). A continuum damage model (CDM) based on Tsai-Wu criterion was established to simulate the damage behavior of CGFR-PP. Tensile and bending tests on CGFR-PP and single lap shear (SLS) tests were conducted to verify the validity of the CDM and CZM. At last, the finite element model was used to predict the bending properties of the anti-collision beam, and the error of maximum load is approximately 5 %. Results reveal that the simulation results demonstrated a good agreement with the experimentally obtained force-displacement curves in terms of stiffness and maximum load.

The Children in Need in Postwar Macedonia (1944–1950)
Authors: Miovska-Spaseva Suzana
Published: December 2024

The article examines the educational and social needs of children in the devastated and impoverished People’s Republic of Macedonia (Narodna Republika Makedonija – NRM) as one of the constituent units of the yugoslav Federation (Federativna Narodna Republika yugoslavia – FNRJ) in the first years after the end of World War II. The focus is primarily given on the measures and activities that the Macedonian policy makers undertook in the areas of education and social protection of children and the changes their implementation brought in children’s life. Based on the study of a large number of legal acts and other primary sources, the various aspects of the democratization of education and social care in the new postwar political context are examined: expansion of the school network, access to educational and social institutions and services for all children, recognition of the right to education in the mother tongue, establishment of pre-school education, special education and the protection of vulnerable children. The research interest is also focused on the needs of a large number of children refugees, mostly Macedonians, who were evacuated during the civil war in Greece from its northern parts and sent to the socialist states in the Balkans and in Eastern Europe. Most of them were housed in yugoslavia and especially in Macedonia, which in 1948 became the largest transit center and shelter for thousands of children in need. Based largely on archival material and testimonies of child refugees, the article sheds light on the process of evacuation of children, their life in children’s homes throughout Macedonia and the endeavors of the state to meet their needs for shelter, food, education and normal life.
“Every City Dweller is, if not Ill, at Least in Need of Recovery.”1 The Schullandheim (Rural School Hostel) in the Context of Crisis and Reform after the First World War
Authors: Berner Esther
Published: December 2024

Rural school hostels have hardly been the subject of interest in educational history to date. This is despite the fact that after the First World War an actual rural school hostel movement was formed in Germany and corresponding institutions still exist today. The founding of rural school hostels can be placed in the post-war context, which was characterised by crises. At the same time, their success is fuelled by a multitude of intersecting and mutually reinforcing discourses whose origins go back further. These are reconstructed in this article under keywords such as urbanisation, hygiene and community education. While the hygienic objectives (health, nutrition, architecture, etc.) followed a logic of objectification and standardisation, the ideal of a personalised close relationship between teacher and pupils was guided by modes of subjectivity and individualisation. The combination of these two tendencies merged sometimes into ideas of pedagogical omnipotence. Moreover, the focus on the individual child was always framed by an overarching collectivising idea of community, which was to take on increasingly totalitarian traits at the transition to and during National Socialism.

This article analyses the phenomenon of pedagogization in relation to the implementation of a new school subject. The aforementioned subject is called “Wirtschaft / Berufs- und Studienorientierung” within the German federal state of Baden-Württemberg and was instituted in 2016. Even before the launch, a huge media dispute about the role of economic knowledge in schools ensued. Politicians, the scientific community and foundations weighed in on the design of the school subject. The article presents these actors and their view on the matter as a phenomenon of pedagogization, as the subject was continuously described as a rudimental contribution to solve a multitude of societal problems.
Sovietization in Poland and its Impact on Education and Pedagogy
Authors: Kostkiewicz Janina
Published: December 2024

The purpose of this article is to identify the roots of the phenomenon known as Sovietization, and to explore its implementation in Polish education and pedagogy. In Poland (and other countries of Central and Eastern Europe), which was left in Stalin’s sphere of influence as a result of the conferences at yalta (February 4–11, 1945) and Potsdam (July 17, 1945 – August 2, 1945), Sovietization is a painful page of history. Understood as the imposition of economic, social, and cultural solutions modeled on Soviet Russia and then the USSR, combined with communist indoctrination, it had negative consequences for education and pedagogy. These effects resulted from the anthropological and cultural assumptions of Sovietization, which were implemented in education by the creation of a new paradigm of knowledge about education – socialist pedagogy. The history of Sovietization in Poland had two politically distinct stages. It operated 1) during the period of Polish independence (1918/20 – 1939) and 2) during the period of communist enslavement (1945–1989). In the first period, the influence of communism was limited. The second stage, which represents an interesting and at the same time cruel experience of the Poles, demands greater attention from historians.

Chemotherapeutic agents result in the loss of growing follicles, which can manifest as amenorrhoea. Alkylating chemotherapy (AC) is known to be more gonadotoxic than non-alkylating chemotherapy (NAC). Anti-Müllerian hormone (AMH), an indirect marker of ovarian reserve, and age have been investigated as predictors of ovarian function after chemotherapy; however, little is known about the time to return of menses. This study aimed to assess how patient age and baseline serum AMH levels at cancer diagnosis affect the time to return of menses post-chemotherapy. This retrospective cohort study examined oncology patients (n = 67) who underwent chemotherapy and were treated through the Reproductive Services Unit of two institutions in Melbourne, Australia. Primary outcomes included the correlation between age and baseline AMH with time to return of menses after chemotherapy. Secondary outcomes include the change in AMH levels at 6- and 12-months post-completion of chemotherapy. Pairwise correlation of the pre-chemotherapy AMH level and time to return of menses demonstrated statistical significance (Spearman’s coefficient, ρ = −0.40) for patients who underwent AC. This analysis in breast cancer patients who underwent AC displayed a negative correlation but was not statistically significant. No association was found between age and time to return of menses for all cancer (NAC or AC) or breast cancer patients who underwent AC. Higher AMH levels prior to AC were associated with an earlier return of menses after chemotherapy. Age at the commencement of chemotherapy was not associated with return of menses. Further prospective research is required to assess post-chemotherapy recovery of AMH.

Lay summary

Chemotherapy, used to treat cancer, is known to damage women’s ovaries, with certain types having a more toxic effect than others. This may result in a temporary loss of periods while undergoing chemotherapy. AMH is a hormone produced by the ovaries and gives an indication of their level of function. This study looks at whether an individual's AMH or age when beginning chemotherapy can predict the time before the resumption of periods after completing chemotherapy. This study found that for cancer patients who underwent the chemotherapy type known to be more toxic to ovaries, the higher their AMH level was before beginning chemotherapy, the more rapidly their periods would return after completing chemotherapy. Age was not found to accurately predict how rapidly periods would return after completing chemotherapy. This information can be used to inform patients before treatment of the chances of periods returning and, consequentially, pregnancy after the completion of their chemotherapy.
Working with all nations and all relatives in feeding the future
Authors: Shukla Shaileshkumar
Published: December 2024

Most unprecedented changes and challenges to planetary health that include earth and human health, are attributed to short-sighted policies and systemic barriers. Standardized and top-down approaches of development that often dominate through limited, persuasive, and extractive euro-centric perspectives often dominate in Turtle Island and most colonial regions of the world. Food and food-sustaining relatives (land, water, plants, animals, micro-habitats) which are central to planetary health, are negatively impacted and threatened by these human pressures, which have severe implications for our ability to feed current and future generations (FAO et al., 2023; Planetary Health Alliance, n.d.). Many international agencies (including those affiliated with the United Nations), food systems scholars, grassroots organizations, and community members are grappling with the very imminent challenges of addressing the alarmingly high level of food insecurity in Turtle Island (Council of Canadian Academics, 2014; Fieldhouse & Thompson, 2012) and the global South (Kuhnlein et al., 2013).
Notas sobre evolución y paleoantropología en el Nachlaß blumenberguiano
Authors: Ros Velasco Josefa
Published: December 2024

Hans Blumenberg escribió, en un manuscrito inédito titulado “Ein Betrug? / Der böse Dämon” (UNF 532–534), que “el mundo entero y la inteligencia humana estaban escondidos bajo la tierra, en la que reposan las reliquias de los precursores de la vida”. El filósofo alemán no era paleoantropólogo en el sentido estricto de la palabra, pero dedicó gran parte de su vida a excavar en la tierra en busca de respuestas a las grandes preguntas por la condición humana. Este artículo es el resultado de un trabajo de compilación y clasificación de una serie de inéditos sobre paleoantropología que pueden encontrarse dispersos en el Nachlaß de Blumenberg. El objetivo es mostrar el interés que disciplinas como la paleoantropología despertaron en este pensador y que su conocimiento en la materia, reflejado en parte en sus tesis antropológico-filosóficas, está por sistematizar.
Una reinterpretación naturalista de la función compensatoria de la metáfora y el mito en la filosofía de Hans Blumenberg
Authors: Zorita Arroyo Diego
Published: December 2024

La reflexión sobre la función compensatoria del mito y las metáforas absolutas está presente ya en los Paradigmas para una metaforología. Sin embargo, los presupuestos antropológicos en que dicha función se basa son expuestos por Blumenberg en Trabajo sobre el mito y sistematizados en la obra póstuma Descripción del ser humano. En este artículo repaso estas tres obras en relación con la función compensatoria del mito y las metáforas absolutas, expongo críticamente los presupuestos antropológicos en que se funda —que Blumenberg extrae de la antropología filosófica alemana— y propongo una fundamentación alternativa en la que basar la función compensatoria de estas representaciones imaginarias.
Presencias del absoluto. Variaciones sobre un tema blumenberguiano
Authors: Durán Guerra Luis
Published: December 2024

De todos los absolutismos a los que se ha referido Hans Blumenberg, el de la realidad es el más importante —aunque no fuera el primero en ser formulado— en la medida en que, en virtud de su impronta antropológica, redimensiona y acaba otorgando a los demás valores del término un sentido meramente derivado o, cuanto menos, específico. No me ocuparé en este artículo de todos los absolutismos blumenberguianos ni tampoco de las respuestas que generan como desafíos presentados al ser humano en su devenir histórico, sino que me limitaré a ilustrar con algunos ejemplos tres tipos de absolutismo fundamentales para entender el pensamiento de Blumenberg: el absolutismo teológico, el absolutismo de la realidad y el absolutismo del libro.
Las fronteras y las murallas de la pobreza
Authors: Espinosa Antón Francisco Javier
Published: December 2024

Cuando la gente oye hablar de las fronteras de la pobreza se imagina unas líneas espaciales que dividen el mundo entre los países en situación de pobreza y los países en situación de riqueza: son las murallas que dificultan la inmigración. Hay otras murallas más imperceptibles, pero no por ello menos importantes. Las personas en situación de pobreza severa en el mundo no pueden ver el futuro porque la muralla de su presente desolador se interpone. Por otra parte, la compasión nos encierra en una muralla que nos impide acceder a la humanidad de las personas en situación de pobreza. Nuestro nacionalismo, además, nos pone una muralla que nos cierra el paso a la construcción de una justicia global. Finalmente, las fronteras del mercado encierran al periodismo que trata de la pobreza a través de unas murallas de injusticia. Como se ve, aunque nos parezca paradójico, somos nosotros los que tenemos más fronteras y murallas.
La ciudadanía y el derecho a la libertad de movimiento: tensiones y privilegios
Authors: Ortiz Gala Irene
Published: December 2024

Este artículo aborda las tensiones que se producen entre el estatus jurídico de la ciudadanía de cada individuo y el derecho fundamental a la libertad de movimiento. Se examinan varios problemas presentes en conciliar el igualitarismo jurídico con el derecho soberano de cada Estado a limitar la libre circulación en función de la ciudadanía que ostente un sujeto. Finalmente, se sugieren algunas líneas de fuga que se han propuesto desde la filosofía política para apostar por una defensa radical de la libre circulación.
El fondo de precariedad como negatividad inherente al neoliberalismo: una crítica a la dialéctica binomial de Byung-Chul Han
Authors: Morán Roa Alberto
Published: December 2024

Byung-Chul Han plantea que neoliberalismo opera de modo que los sujetos constituidos dentro de su marco de acciones se explotan libremente a sí mismos. Así, plantea una diferencia entre la forma de poder contemporánea, basada en la positividad, y las del pasado, basadas en la negatividad del castigo y la coerción. Sin embargo, ¿es así? En este artículo se planteará que Han omite el papel de la negatividad en el neoliberalismo: desde su dimensión punitiva a su fondo de precariedad. Su esquema dialéctico, en exceso binomial, pasa por alto el papel constitutivo de la negatividad, su papel irreductible.
La igualdad de oportunidades en disputa. Igualitarismo y meritocracia en el postneoliberalismo
Authors: Rendueles César
Published: December 2024

En los últimos quince años los problemas teóricos y prácticos relacionadas con la desigualdad social han cobrado una visibilidad pública, tanto en los medios de comunicación como en las investigaciones académicas, apenas imaginable antes del inicio de la Gran Recesión. Sin embargo, ese renovado interés por la estratificación social se ha enfrentado sistemáticamente al vigor consensual del paradigma meritocrático de la igualdad de oportunidades, que a menudo es percibido como el único horizonte igualitarista compatible con una democracia moderna y una sociedad compleja. Este artículo emplea un bagaje metodológico interdisciplinar para rastrear las transformaciones de los espacios sociales y morales en los que ese sentido común meritocrático está arraigado y explora, a su vez, la potencia de otras posiciones más profundamente igualitaristas.
La consulta filosófica y la crítica de la normalización social
Authors: Barrientos Rastrojo José
Published: December 2024

La consulta filosofía ha sido criticada al considerarse como una actividad normalizadora y adaptadora al sistema social. Si así fuera, esta disciplina se desacreditaría filosóficamente, al entrar en liza con una de las bases de la filosofía: sus dimensiones críticas. La crítica implica la capacidad de poner en duda las bases del sistema ideológico y, así, evitar quedar alienado; de hecho, el individuo alienado aceptará sin cuestionamiento alguno la realidad dada. Este artículo explora la validez de esta argumentación recriminatoria hacia la consulta filosofía partiendo de la teoría, los textos y las prácticas de los principales representantes de la disciplina a nivel nacional e internacional.
Reconocimiento recíproco en Habermas, Honneth y Cortina: de lo justo, lo bueno y lo cordial
Authors: Calvo Patrici
Published: December 2024

Recientes estudios han destacado el componente emocional y moral de la cooperación humana. Más allá de los beneficios extrínsecos esperables tras la satisfacción de un objetivo común, el reconocimiento recíproco entre las partes implicadas y afectadas se entiende hoy como un prerrequisito o condición de posibilidad para establecer, fortalecer y proyectar relaciones colaborativas. Este estudio busca profundizar en la base ética y afectiva de la cooperación humana a través de la teoría del reconocimiento recíproco mediante de las aportaciones de Jürgen Habermas, Axel Honneth y Adela Cortina.
Signos y símbolos en la filosofía de San Agustín: una aproximación desde la hermenéutica de Paul Ricoeur
Authors: Soto Rangel Laura Alicia
Published: December 2024

El siguiente trabajo analiza la importancia del signo y el símbolo en la hermenéutica contemporánea de Paul Ricoeur en diálogo con la hermenéutica de San Agustín. A través de una comparación entre las teorías hermenéuticas de ambos filósofos, se examinan textos clave como De Doctrina Christiana (395 d.C.) de San Agustín, y se contrastan con la interpretación del símbolo en la hermenéutica de Ricoeur. El objetivo es demostrar cómo la problematización del lenguaje propuesta por San Agustín ofrece una perspectiva valiosa en las teorías hermenéuticas actuales
