Authors: Supianawati Aflahannadwayoanprayoga , Desti Puswati
Published: February 2025

The Elderly Posyandu is a community-based health service aimed at improving the health and quality of life of the elderly. In the Puskesmas Melur area, Pekanbaru City, only 21.3% of 2,925 elderly individuals visited the Posyandu in 2023, and just 5% were active as of September 2024, far below the 80% target. Factors contributing to low attendance include limited activity variations, lack of family support, and low motivation. Many elderly individuals feel bored as activities are limited to weighing and blood pressure checks. This study aims to identify factors associated with low elderly attendance at Posyandu in the of Puskesmas Melur. This quantitative study used a cross-sectional design conducted in the Puskesmas Melur from October to December 2024. The study involved 93 elderly individuals selected using accidental sampling. Research instruments included questionnaires measuring family support, the role of cadres, and elderly knowledge. Data were analyzed using univariate and bivariate analysis (chi-square test, p<0.05). Results showed that most respondents had low family support (53.8%), unsupportive cadre roles (58.1%), and low knowledge (52.7%). The analysis revealed significant relationships between family support (p=0.000), cadre roles (p=0.013), and knowledge (p=0.000) with elderly attendance at Posyandu. This study recommends strengthening health education, optimizing the role of Puskesmas Melur and Posyandu cadres through training and socialization, enhancing family support, and encouraging further research to increase elderly participation in Posyandu.

Authors:   National University of Science and Technology POLITEHNICA Bucharest, POPESCU Liviu
Published: February 2025

One of the simplest ways to rapidly obtain the main characteristics of an EV (Electric Vehicle) powertrain is by calculating the requested values from resistant forces acting on the vehicle. A powertrain covering the operation area of the vehicle can give satisfaction. The autonomy is sustained by the on-board energy source (battery) and the maximum speed and acceleration performances come from the possibility of establishing and maintaining a maximum current through the battery, power electronics, and electric motor. In this context, the present paper is focused on a possible methodology achieved using a computer-aided conception. After determining the characteristics of each powertrain component using calculation and simulation, the behavior of the EV is analyzed under a complete simulation of the powertrain.

Nanostructured Garcinia mangostana Extract Modulates RANKL Signaling and Calcium Homeostasis to Enhance Fracture Healing in Diabetic Bone: A Systematic Review of In Vivo Evidence
Authors: Adhimas Wicaksono  , Yuriz Bakthiar  , MI Widiastuti
Published: February 2025

Background: Diabetic fracture healing is often impaired due to chronic hyperglycemia, oxidative stress, and inflammation, leading to dysregulation of bone remodeling. Receptor activator of nuclear factor kappa-Β ligand (RANKL) and calcium homeostasis are critical regulators of this process. Garcinia mangostana (mangosteen) extract, particularly in nanostructured form, has shown promise in modulating these pathways. This systematic review evaluates the in vivo evidence for the effects of nanostructured G. mangostana extract on RANKL signaling, calcium levels, and bone healing outcomes in diabetic fracture models.
Methods: A systematic search was conducted in PubMed, Scopus, Web of Science, and Embase databases from January 2013 to May 2024. Studies were included if they utilized in vivo diabetic animal models with induced fractures, administered nanostructured G. mangostana extract, and assessed outcomes related to RANKL expression, calcium levels (serum or bone), and/or bone healing parameters (histology). Risk of bias was assessed using the SYRCLE's tool. Data were extracted and synthesized narratively.
Results: Seven studies met the inclusion criteria. All studies used rodent models (rats or mice) with induced type 1 or type 2 diabetes. Nanostructured G. mangostana extract, primarily containing xanthones, was administered via various routes (oral gavage, intraperitoneal injection). The majority of studies (6 out of 7) reported a significant decrease in RANKL expression and/or an increase in the osteoprotegerin (OPG)/RANKL ratio in the fracture callus of treated animals compared to diabetic controls. Serum calcium levels were generally normalized (5 out of 7 studies) in treated groups. Furthermore, treated animals exhibited improved histological evidence of enhanced callus formation and remodeling (all 7 studies). Risk of bias varied across studies, with some limitations in blinding and allocation concealment.
Conclusion: Nanostructured G. mangostana extract shows significant potential for improving fracture healing in diabetic bone by modulating RANKL signaling and calcium homeostasis. Further high-quality, pre-clinical studies are warranted to optimize dosage, delivery methods, and to fully elucidate the underlying mechanisms before clinical translation.
Assessment Of The Implementation Of The Provisions Of The Istanbul Convention In Ukraine
Authors:   Yuriy Fedkovych Chernivtsi National University, MEDINA Tetiana
Published: February 2025

The article is devoted to studying the state of implementation of the provisions of the Istanbul Convention in Ukraine, which is an important stage in combating gender-based and domestic violence. The study is based on the materials of focus groups covering key participants in combating violence in the Chernivtsi region. The level of awareness among participants involved in preventing and responding to violence cases including social workers, police officers, representatives of religious communities, and those responsible for the territorial communities was analysed. It was determined that the ratification of the Istanbul Convention contributed to increasing attention to the problem of violence and the development of the appropriate infrastructure to combat fierceness. However, the general level of awareness of participants regarding the standards of the Convention remains low which complicates the effective implementation of its provisions. Numerous problems were identified including a lack of coordination between participants and a low level of trust of victims in the police, a lack of programs for working with perpetrators, a stereotypical perception of the violence in society, staff shortages and turnover, and low effectiveness of protective orders. To improve the implementation of the Istanbul Convention, it is proposed that additional resources be attracted, employee motivation should be increased, and professional training programs should be developed. An important direction is the involvement of religious organizations in educational work, victim support initiatives, and spiritual guidance which will contribute to strengthening public support and changes in attitudes towards the problem of violence. The article outlines the prospects for further research in the field of analysing the implementation of state and regional action plans. It also studies the experience of victims and the influence of international organizations on the implementation of the Convention. The results can be used to improve mechanisms for combating violence and develop new approaches in social and legal practice.

STYLISTIC SYNTAX AND STRUCTURE OF AUTHORʼS NOTES IN THE WORKS OF OLНA KOBYLІANSKA
Authors: STRUK Ivanna
Published: February 2025

The article analyzes the syntactic status and structure of authorʼs notes, peculiar insertions-remarks in the texts of Olha Kobylianskaʼs prose works. The main groups of remarks that characterize the speech of the characters, explain their non-verbal behavior, describe the feelings, thoughts, experiences of the characters and the narrator are highlighted. Certain stylistic features of replicas in the writer’s prose texts, which represent O. Kobylianska’s creative individuality, have been revealed.
The use of remarks in O. Kobylianska’s prose texts is not accidental. The possibilities of remark constructions satisfy the author’s need to “intervene” in the immediate narrative with additional messages or favorable comments. Therefore, they are an important element of the authorʼs style. It is in the remarkable construction that the author acts as the subject of speech, whose consciousness forms not only his own thoughts and views, but also encompasses the world of the hero of the work of art. In this way, the remark acts as a kind of mediator in the communicative act between the hero (the subject of speech, the addressee) and the reader (the subject of perception, the addressee).
Introductory and accompanying remarks in O. Kobylianskaʼs prose works are valuable material for linguistic observations, they make it possible to generalize information about the original manner of storytelling of the writer. In the introductory remarks, the author names the place and time of the action, introduces the acting characters, gives their characteristics, indicates what they are busy with at the initial moment of the action. Accompanying remarks penetrate the dialogues or accompany the lines of the heroes, contribute to the promotion of the development of actions.
O. DOVZHENKO’S MASTERY IN VERBALIZING GENDER IMAGES IN THE WRITER’S DIARY TEXT
Authors: KOSMEDA Tetyana
Published: February 2025

The scientific study is conducted within the paradigm of diary studies, gender linguistics, linguistic personology, and linguistic stylistics. These research perspectives allowed for a multifaceted portrayal of O. Dovzhenko as a refined Ukrainian linguistic personality, which manifests in his unique verbalization of national images of жінка / дівчина (woman / girl) in all their roles (матір, дружина, сестра, дочка (mother, wife, sister, daughter)), juxtaposed with the masculine images of Ukrainian чоловік / парубoк (man / young man). To verbalize these images, the writer activates nationally colored meanings and creates a system of national figurative linguistic means (expressive epithets, individual comparisons, refined metaphors, affective-diminutive forms, and precedent national names). Dovzhenko, as a diarist, reveals the sincerity of his feelings, demonstrates his intentions, and models intimating meanings.
In the text of the examined diary, there is frequent use of female designations by profession and occupation with the activation of specifically feminine forms, contrasted with masculine forms, which indicates that the use of feminine forms has a long-standing tradition.
Female images are contrasted with male ones, taking into account the context of the war and post-war period, when the widow bore a heavy burden. It is presented by modeling unique individual-author figurative nominations, also projected onto the image of a girl who could not marry due to the lack of men. The contrast between the old man and the old woman is also drawn. Following national tradition, O. Dovzhenko verbalizes patriarchal male consciousness, depicting a negative image of the old woman.
O. Dovzhenko critiques certain trends in the upbringing of girls and naming practices that do not correspond to Ukrainian traditions, as well as a new level of relationships between girls and young men, employing irony.
A FILM PORTRAIT OF AN ELITE LINGUISTIC PERSONALITY: LINGUISTIC AND STYLISTIC RECEPTION (BASED ON DOCUMENTARY FILMS ABOUT O. DOVZHENKO)
Authors: GANZHA Anhelina
Published: February 2025

The study attempts to make a linguistic and stylistic reception of two documentary film portraits of Oleksandr Dovzhenko: “Oleksandr Dovzhenko. Odesa Dawn” (2014) and “Oleksandr Dovzhenko. Lost Love” (2020). Both media products were created by professional teams of authors and highlight different facets of the writer’s fate and talent.
The documentary “Oleksandr Dovzhenko. Odesa Dawn” is not very informative about the specifics of the linguistic portrait of the protagonist, a prominent Ukrainian filmmaker, but the film clearly represents the arsenal of tools for creating a film portrait of an elite linguistic personality.
The documentary “Oleksandr Dovzhenko. Lost Love” forms an idea of the linguistic portrait of the film’s protagonist, which emerges from Dovzhenko’s quotes, the host’s comments and the voiceover text. This media product correlates elitist linguistic personalities – the protagonist of the film Oleksandr Dovzhenko and the host of the TV series “The Game of Fate” Natalia Sopit.
The concept of an elite linguistic personality implies a perfect command of the norms of the literary language and all its functional styles; the ability to create and understand texts of varying complexity; possession of skills of influence, persuasion, and attention-getting; and the use of effective strategies and tactics in various types of communication. When it comes to an artist, a creative personality, this list should include the ability to accumulate, multiply and transmit national linguistic culture; a high level of linguistic awareness and linguistic stability. Understanding the specifics of creating a film portrait of an elite linguistic personality allows us to use tools that will ensure the proper level of quality of this requested type of film production and, accordingly, the appropriate level of predictable impact on the formation of the target audience’s value orientations.

Multiband Polarization Profile Analysis of Three-component Radio Pulsars by Implementing a Relativistic Phase-shift Method
Authors: Roy Tridib , Surnis Mayuresh , Das Ramkrishna
Published: February 2025

In this paper, we show the estimation of the emission altitude of pulsars PSRs B0329+54, B0450-18, B2045-16, J1909+0007, and J0337+1715 for both core and conal components at multiple radio bands by implementing a relativistic phase-shift method, which is constrained based on the plethora of standard radio emission geometry. Using the information of pulse longitudes for each component, coupled with a dipolar field geometry, we obtain a rough estimation of the height and transverse location of the emitting cones for these pulsars, i.e., footpoint location of the pulse edge, normalized with the last open magnetic field line constant. We also analyzed the profile of a well-known millisecond pulsar J0337+1715 at 1250 MHz, which has an asymmetric core-cone structure for both the main pulse and interpulse. This is the first time such a case has been analyzed to probe emission height by implementing the relativistic phase-shift method. We discuss the implications of our findings in the context of the pulsar's emission geometry to reach a consensus on the existing emission mechanism of pulsars.

GRB 230812B, detected by the Gamma-Ray Integrated Detectors constellation mission, is an exceptionally bright gamma-ray burst (GRB) with a duration of only 3 s. Sitting near the traditional boundary (∼2 s) between long and short GRBs, GRB 230812B is notably associated with a supernova, indicating a massive star progenitor. This makes it a rare example of a short-duration GRB resulting from stellar collapse. Our analysis, using a time-evolving synchrotron model, suggests that the burst has an emission radius of approximately 1014.5 cm. We propose that the short duration of GRB 230812B is due to the combined effects of the central engine's activity time and the time required for the jet to break through the stellar envelope. Our findings provide another case that challenges the conventional view that short-duration GRBs originate exclusively from compact object mergers, demonstrating that a broader range of durations exists for GRBs arising from the collapse of massive stars.
Universal Constants in Self-organized Criticality Systems
Authors: Aschwanden Markus J.
Published: February 2025

The occurrence frequency distributions of fluxes (F) and fluences or energies (E) observed in the majority (in 18 out of 23 cases) of astrophysical phenomena are found to be consistent with the predictions of the fractal-diffusive self-organized criticality (FD-SOC) model, which predicts power-law slopes with universal constants of α

F
 = (9/5) = 1.80 for the flux and α

E
 = (5/3) ≈ 1.67 for the fluence. The theoretical FD-SOC model is based on the fractal dimension, the flux-volume proportionality, and classical diffusion. The universal scaling laws predict the size distributions of numerous astrophysical phenomena, such as solar flares, stellar flares, coronal mass ejections, auroras, blazars, active galactic nuclei, black hole systems, galactic fast radio bursts, gamma-ray bursts, and soft gamma-ray repeaters. In contrast, we identify five outliers of astrophysical phenomena, i.e., coherent solar radio bursts, random solar radio bursts, solar energetic particles, cosmic rays, and pulsar glitches, which are not consistent with the standard FD-SOC model, and thus require different physical mechanisms.
Unraveling the Nature of HAWC J1844–034 with Fermi-LAT Data Analysis and Multiwavelength Modeling
Authors: Boxi Sovan , Ghosh Saptarshi , Gupta Nayantara
Published: February 2025

The extended ultra-high-energy (UHE) gamma-ray source HAWC J1844–034 is closely associated with two other sources, HAWC J1843–032 and HWC J1846–025. Moreover, other gamma-ray observatories like HESS, LHAASO, and Tibet AS
γ
have detected UHE gamma-ray sources whose spatial positions coincide with the position of HAWC J1844–034. The UHE gamma-ray data from several observatories aid analysis of the spectral features of this source in detail at teraelectronvolt energies. Of the four pulsars near HAWC J1844–034, PSR J1844–0346 is closest to it and possibly supplies the cosmic-ray leptons to power this source. We have analyzed the Fermi–Large Area Telescope (LAT) data to explore this source’s morphology and identify its spectral features in the Fermi-LAT energy band. After removing the contribution of the pulsar to the gamma-ray spectral energy distribution (SED) by pulsar-phased analysis, we obtained upper limits on the photon flux and identified the gigaelectronvolt counterpart PS J1844.2–0342 in the Fermi-LAT energy band with more than 5σ significance, which may be a pulsar wind nebula (PWN). Finally, the multiwavelength SED is modeled, assuming HAWC J1844–034 is a PWN.

Published: February 2025

The light curves of old G dwarfs obtained in the visible and near-infrared wavelength ranges are highly irregular. This significantly complicates the detectability of the rotation periods of stars similar to the Sun in large photometric surveys, such as Kepler and TESS. In this study, we show that light curves collected in the ultraviolet (UV) wavelength range are much more suitable for measuring rotation periods. Motivated by the observation that the Sun’s rotational period is clearly discernible in the UV part of the spectrum, we study the wavelength dependence of the rotational period detectability. We employ the Spectral and Total Irradiance Reconstructions model to characterize the detectability of the solar rotation period across various wavelengths using the autocorrelation technique. We find that at wavelengths above 400 nm, the probability of detecting the rotation period of the Sun observed at a random phase of its activity cycle is approximately 20%. The probability increases to 80% at wavelengths shorter than 400 nm. These findings underscore the importance of UV stellar photometry.

The odd-scaled snake genus Achalinus, which is widely distributed in northern Vietnam, China and Japan, is a poorly-known group of snakes. Numerous species within this genus have been described based on few specimens or only a single type specimen. Achalinus hunanensis Ma, Shi, Xiang, Shu & Jiang, 2023 was described based on only two male specimens from Huaihua City and Changsha City, Hunan Province, China. To date, this species has only been recorded in Hunan Province and the information on females is not available. During our herpetological surveys in 2024, two Achalinus specimens were collected from Guizhou Province, China. We compared morphology and mitochondrial DNA sequence data of these two specimens with all the species of the genus Achalinus. Both datasets strongly supported classification of the adult female specimen from Dushan County to A. hunanensis and the adult male specimen from Xifeng County to A. yunkaiensis.

In this study, we describe the first female specimen of A. hunanensis in detail and provide revised diagnoses of this species based on newly-collected and examined specimens and update the distribution of A. hunanensis and A. yunkaiensis.

Daedaleopsis sinensis is a crucial wood-decaying fungus with significant lignocellulose-degrading ability, which plays a vital role in the material cycle and energy flow of forest ecosystems. However, the mitochondrial genome of D. sinensis has not yet been revealed. In the present study, the complete mitochondrial genome of D. sinensis was assembled and compared with related species. The mitochondrial genome spans 69,155 bp and has a GC content of 25.0%. It comprises 15 protein-coding genes (PCGs), 26 transfer RNA genes, two ribosomal RNA genes and one DNA polymerase gene (dpo). Herein, we characterised and analysed the codon preferences, variation and evolution of PCGs, repeats, intron dynamics, as well as RNA editing events in the D. sinensis mitochondrial genome. Further, a phylogenetic analysis of D. sinensis and the other 86 Basidiomycota species was performed using mitochondrial genome data. The results revealed that four species, D. confragosa, D. sinensis, D. nitida and Fomes fomentarius, were grouped in a closely-related cluster with high support values, indicating that a close phylogenetic relationship existed between Daedaleopsis and Fomes. This study reported on the initial assembly and annotation of the mitochondrial genome of D. sinensis, which greatly improved the knowledge of the fungus. These results contribute to the limited understanding of the mitochondrial repository of wood-decaying fungi, thereby laying the foundation for subsequent research on fungal evolution and ecological functions.

Published: February 2025

Background: Herbal medicine has been an integral part of Bulgarian life and culture for centuries. However, incorrect use, resulting from a lack of adequate or false understanding of medicinal plants’ therapeutic properties, poses serious health risks for patients.

Objectives: The main goal is to determine the sources of information about herbal medicine. Secondary objectives include identifying the most commonly used medicinal plants, the ways to obtain them, and assessing whether herbs are used correctly by respondents.

Methods: A pilot, observational, prospective, cross-sectional online survey was conducted from 19 June 2023 to 31 July 2023. A specific questionnaire with four sections was developed. Statistical analysis was performed using MedCalc software, including descriptive statistics, frequency and graphical analysis, Fisher’s exact test, and chi-squared tests.

Results: The number of respondents was 59, with a predominance of individuals aged 18–30 (57.6%), women (72.8%), and university graduates (64.4%). About 31% suffer from chronic diseases, with the most common being related to the digestive system (n = 3), the nervous system (n = 3), and allergies (n = 3). Herbal medicine is considered an effective therapy by 81.4% (p < 0.0001). For acute diseases, herbs are preferred by 22 patients, while for chronic diseases, by 6. The most widely used herbs are Mentha sp. (n = 18) and Thymus sp. (n = 14) from the Lamiaceae family and Matricaria chamomilla (n = 15) from the Asteraceae family. There is a predominance of herbs reported to be used correctly (n = 123 vs. n = 22, p < 0.0001). Most respondents (70.4%) buy herbs from a herbal pharmacy or drugstore (p = 0.0004). The preferred sources of information are medical professionals (n = 51) and the Internet (n = 31) (p = 0.1080).

Conclusion: A significant number of respondents obtain information from the Internet, which can lead to misinformation. Efforts are needed to develop a reliable online source of information.
Parler de la mort auprès de patients en fin de vie et de leurs familles, entre contexte socioculturel et économique, réseau d’interactions institutionnelles et subjectivité des acteurs
Authors: Alexopoulos de Girard Christina
Published: February 2025

En prenant appui sur une longue expérience clinique en cancérologie et dans la clinique de la fin de vie, ce texte retrace différentes manières d’évoquer et de traiter psychiquement la perspective de la mort auprès des patients et de leurs familles. Il s’y attelle en s’intéressant au contexte collectif, socioculturel et économique dans lequel évolue l’hôpital, au réseau d’interactions institutionnelles qui en régit le mode de fonctionnement, et à la subjectivité des acteurs impliqués, en relation avec leur histoire personnelle, leurs angoisses et leurs modes de défense. Le caractère traumatique de l’annonce de la mort, l’accompagnement difficile de la fin de vie, la gestion du trépas mettent à l’épreuve tant les soignants que les patients et leur famille, en les confrontant à la « détresse du nourrisson », à l’impuissance ou à la culpabilité. Différents modes d’accompagnement sont alors mobilisés, en relation avec les ressources des personnes concernées, leurs valeurs culturelles et socioprofessionnelles, mais aussi des considérations plus pragmatiques, souvent incompatibles avec une prise en soin respectueuse du sujet et de son désir. Les différents positionnements des acteurs sont tributaires du travail d’élaboration de leurs enjeux inconscients aux niveaux individuel et groupal, mais aussi d’injonctions économiques et idéologiques qui nécessiteraient également un travail de déconstruction. Prendre conscience de différents déterminismes qui agissent sur son travail de soignant est une condition sine qua non pour s’en dégager et réussir à mieux accompagner les patients dans leur singularité.

Parkinson’s disease (PD) is a neurological condition that affects approximately 10 million individuals globally and is ranked as the second most prevalent neurodegenerative condition after Alzheimer’s disease. Vocal disorders can be identified in approximately 90% of PD patients in the early stages of the disease. In this study, 19 machine learning (ML) algorithms were applied to a database of voice recordings of healthy individuals and individuals with PD obtained from a public repository. Different feature selection (FS) and hyperparameter optimization techniques were applied to all models for training, testing, and validation data. Among the ML algorithms, support vector machine with radial kernel, Naïve Bayes (NB), and Gaussian process classifier (GPC) yielded promising results when considering all features. Linear discriminant analysis, K neighbors classifier (KNN), extra trees classifier, GPC, and NB demonstrated excellent performance on the testing data after employing FS techniques. Decision tree classifier, KNN, and GPC emerged as the top performers when applied to the validation dataset. Our findings, derived from an extensive and chronological review of studies utilizing the same dataset, which surpass previous benchmarks, provide a comprehensive understanding of ML’s application in voice analysis to support accurate clinical decision-making.
Development of GLCM Method in Calculate Entropy Value for Digital Visualization in Identifying Childhood Pneumonia Based on Chest X-Ray Images
Authors: Rianti Eva , Fitri Iskandar , Sumijan  , Fitry Yani Finny
Published: February 2025

Pneumonia can affect people of all ages, especially children. One way to identify pneumonia is by using medical equipment through radiological examinations such as chest X-rays. This study proposes the development of an entropy formula found in the gray level co-occurrence matrix (GLCM) texture extraction method to automatically detect pediatric chest X-ray results in identifying pneumonia. The pre-processing stage is tested with several steps, including converting RGB to grayscale, adaptive histogram equalization (AHE), filtering, Otsu thresholding, image inversion, and automatic image cropping. After preprocessing is the segmentation stage that conducted by processing the image from the cropping results. The testing process in the segmentation stage includes contrast enhancement, Otsu multi-thresholding, border clearing, and image segmentation. The results from the segmentation process are then followed by the extraction stage. The extraction stage focuses on developing the entropy value found in GLCM, referred to as the entropy value algorithm with gray level co-occurrence matrix (EVAGLCM). The key contributions of this study lie in the advancement of digital image processing methods for the accurate identification of childhood pneumonia through improved texture feature extraction. This study compares the developed entropy value with several previous studies. The development of this entropy value is then followed by the classification stage using a support vector machine (SVM). The accuracy achieved in this study was 97.5%, meaning it was able to accurately detect 390 images out of 400 images. This indicates that the entropy value calculation using the EVA-GLCM formula and classification using SVM can provide more accurate output with a higher accuracy rate.
La métaphysique par-delà l’ontologie et l’esthétique
Authors: Moulin Isabelle
Published: February 2025

L’article cherche à montrer que la métaphysique ne suit pas une évolution historique linéaire mais hélicoïdale et que l’oubli de l’être ne signifie pas la fin de la métaphysique. Une telle science, « toujours recherchée » est ainsi « toujours manquante » et ne peut se circonscrire dans une temporalité déterminée. La fin de l’ontologie et de l’esthétique ne signe pas l’arrêt de la métaphysique. Pour l’établir, l’autrice montre comment la métaphysique traditionnelle est pétrie d’attributivisme et comment le cheminement qualitatif de la beauté y échappe ; ce qui lui permet, dans un second temps, d’introduire une dimension dynamique dans la substance qui doit s’entendre de manière auto-créatrice dans un processus d’ontogenèse. La dernière partie trace les grandes lignes, les outils et les éléments fondateurs de ce que pourrait être une métaphysique qui ne se réduit ni à une ontologie stricte, ni à une esthétique, mais une métaphysique du « beau », qui redéfinit la substance de manière dynamique, ainsi que ses cadres spatio-temporels.
The Hard Material Challenges of Extreme Poverty, Destitution and Housing to Wellbeing in the United Kingdom
Authors: Sowels Nicholas
Published: February 2025

This article1 explores the interaction between inequality, poverty and wellbeing in the UK, particularly in recent years – post-Covid and Brexit – noting that the decades-long decline in absolute poverty in the UK has levelled off since the global financial crisis (2007 to 2009). This is a major change, reflecting the fact that British society today is no longer becoming better-off. Ironically, at the same time, income inequality and relative poverty levels have been fairly stable since the 1990s (following big rises during the Thatcher years of the 1980s), though the “Top 1%” of income owners have continued to pull away. The article points out that some significant policies – notably the efforts to tackle child policy by New Labour (1997 to 2010) and the widespread support for household incomes during the Covid pandemic – did temporarily alleviate some aspects of poverty. However, subsequent phases of public spending control and/or a shift to more conventional policies led to the return to pre-existing conditions: most worryingly, there has been a notable increase in “destitution” since the late 2010s. The article also examines trends in housing costs, which are uniquely taken into consideration in British income inequality and poverty statistics, pointing to some structural trends in housing that strongly undermine household wellbeing.
