Purpose: To conduct a quantitative analysis of the quality of irradiation planning for patients with metastatic lesions of the spine, to assess the dose load on critical organs for this category of patients, to establish the relationship between patient survival and the homogeneity index.Material and methods: A quantitative analysis of stereotactic irradiation plans for 65 treated patients with simultaneous integrated boost (SIB) was performed. Plans (not implemented) were simulated for a group of patients with an increased prescribed dose to the affected vertebra, including an invisible expected zone of microscopic spread of malignant cells. Dose loads in critical organs for irradiation plans using IMRT and VMAT technology with metastatic lesions of the spine were estimated for both groups. Homogeneity indices were calculated.Results: The results of the quantitative analysis of the plans for stereotactic irradiation of patients showed that the doses in critical organs in the simulated irradiation plans slightly exceed the same doses, but, nevertheless, are comparable with the characteristics of the integrated boost (SIB) technique and fit into the tolerable dose values in accordance with international criteria. The characteristics are also comparable in terms of the homogeneity index. The hypothesis of the effect on the life expectancy of patients after RT, including the value of the homogeneity index as one of the factors affecting survival times, was not statistically confirmed. The simulated irradiation plans for patients with an increased prescribed dose to the affected vertebra, including an invisible expected zone of microscopic spread of malignant cells, can be applied to the implementation and treatment of patients with metastatic lesions of the spine. Homogeneity indices H I were calculated. It was shown that the survival time for patients with a dose to the PTV of 25 Gy with HI ≥ 0.15 is limited to 18 months, and for HI ≤ 0.15 it increases to 29 months with a statistical significance level of p = 0.647. Similarly, the survival time for patients with a dose to the PTV of 30 Gy with HI ≥ 0.15 is limited to 16 months, and for HI ≤ 0.15 it increases to 29 months with a statistical significance level of p = 0.936, which reflects the absence of differences between the groups.Conclusions: The obtained results indicate that the hypothesis about the influence of the homogeneity index on life expectancy is not confirmed. For final conclusions, it is necessary to continue the study, possibly with an increase in the sample or the inclusion of additional influencing factors.

Published: January 2025

Purpose: To investigate the structure of adverse post-radiation reactions occurring after radiosurgical treatment of cavernous malformations (CMs) and to identify factors influencing their frequency.Material and methods: Between September 2005 and September 2020, 123 patients with single CMs of the brain (a total of 123 CMs) were irradiated at the center. The final analysis included 67 patients. Dose distribution data were subjected to regression analysis.Results: Nineteen cases of post-radiation edema (28.3 %) and two cases of post-radiation necrosis (2.9 %) were identified. During the observation period, ten patients experienced hemorrhage from the irradiated CM (14.9 %). The dose received by 50 % of the target volume (including the planning target volume) was determined to be the most significant predictor of post-radiation edema development in patients after radiosurgery for single cavernomas.Conclusion: In cases of deep-seated CMs, microsurgical removal is associated with a high risk of complications. In such cases, radiosurgery can be offered as a safe alternative to microsurgery.
Conversational Regulators in American Sign Language Students
Authors: Mcdermid Campbell , Lipps Jacob
Published: January 2025

Language proficiency can be framed as grammatical, sociolinguistic and strategic competency. Historically, the grammatical strategies of hearing students who study American Sign Language (ASL) have been emphasized. To address this gap, a Discourse Completion Task was designed to look at a little explored area, conversational regulators, in 14 hearing students who had taken ASL 1 (one semester) as compared to 14 hearing students who reported taking no ASL classes. Participants watched and responded to 11 videotaped contexts in ASL. The findings indicate that the ASL1 students had learned various ASL conversational regulators, such as frowns (* p = .00) and hand waving (the HEY sign in ASL) (* p= .00). They followed Deaf culture norms for not talking and gesturing at the same time (* p = .00). They also demonstrated reduced use of miming compared to the non-ASL students (* p = .00). The findings are discussed within the context of existing literature, and recommendations are offered for future research and practice.

Modified Hughes Tarsoconjunctival Flap Procedure for Lower Eyelid Defect: A Case Series
Authors: Aulia  , Hendriati
Published: January 2025

Background: The Hughes procedure, or tarsoconjunctival flap, is a technique used in reconstructing full-thickness lower eyelid defects involving >50% of the eyelid margin to restore anatomical integrity, function, and cosmesis of the eyelid. The modified Hughes procedure spares the marginal upper lid tarsus and removes the levator muscle aponeurosis from the tarsoconjunctival flap. This study reports a case series of patients who underwent a modified Hughes procedure after basal cell carcinoma excision.
Case presentation: Two patients underwent lower eyelid reconstruction using the modified Hughes procedure. After a wide excision of the tumor, a tarsoconjunctival flap was created to reconstruct the posterior lamella of the eyelid. Subsequently, the anterior lamella of the eyelid was reconstructed using a full-thickness skin graft and an advancement flap, respectively. Both patients underwent a second surgery, tarsus flap release, 6-8 weeks after the first surgery. Postoperatively, tarsal flap apposition, skin flap/graft, and stitches were intact. After the tarsus flap release, wound healing was good. A tumor biopsy showed basal cell carcinoma.
Conclusion: The modified Hughes procedure is a treatment of choice in reconstructing full-thickness lower eyelid defects involving >50% of the eyelid margin. Full-thickness skin graft and advancement flap to reconstruct the anterior lamella of the eyelid are chosen after considering skin color, texture similarity, and the laxity of the eyelid and cheek.

В статье приведены результаты исследования гинекологических патологии, наиболее распространенными среди которых были патологии матки до 50%, в том числе клинически выраженного эндометрита до 30%, субклинического эндометрта – до 13%, субинволюции матки – до 12%.  После первого осеменения до 30-40-го дня после отёла, стельными оказались до 20,0% животных, что приблизительно в 2 раза ниже, чем в более поздние сроки.
До настоящего времени бесплоди причиняет большой  экономический ущерб  животноводству РК . Бесплодие — это лишь признак или следствие какого-либо состояния (в том числе болезни), в результате которого нарушается воспроизводство стад. Это нарушение воспроизводства маточного стада и ремонтного молодняка как результат воздействия стресс-факторов (алиментарного, климатического и др.), погрешностей в искусственном или естественном осеменении, болезней репродуктивных органов, иммунных реакций. Таким образом, бесплодной следует считать корову не осеменённую либо осеменённую, но не оплодотворившуюся в течение двух месяцев после отёла (или спустя 1 месяц после завершения физиологических сроков инволюции половых органов).
Восстановительные процессы в матке протекали медленнее, но достигаемая за счёт овариостимуляции стабилизация функциональной деятельности яичников ускоряли восстановительные процессы в матке. В последующих  работах  мы поставили задачу провести   акушерско-гинекологическую дипансеризацию маточного поголовья в послеродовом периоде и выявить наиболее распространеные патологий половых органов у коров и разработать эффективные методы лечения  с целью восстановления  функций половых органов, таким образом нами   выявлены в  данном хозяйстве  до 30% бесплодных коров и  основным видом  бесплодия коров было симптоматическое бесплодие , что составляло  67%  это такие патологий как – гнойно-катаральное восполение матки,  патологии яичников  и их функциональное нарушение,  вагиниты, вестибуловагиниты, среди гинекологических патологий самым распространеным были гнойно-катаралбные  эндометриты, поэтому  мы решили применить  для лечения этой патологии , опрабированные нами методы  лечения  и обследовать биохимические  и гематологические  покозателей сыворотки крови коров  при гнойно-катаральном эндометрите до лечения  и после лечения, все  данные результатов  биохимических и гематологических изменений в сыворотке крови коров  обсуждены  в этой статье  и сделаны соответствующие выводы по ним.

Бүгінгі таңда Қазақстан аумағында ең маңызды проблемалардың бірі мал арасында паразиттік аурулардың көп болуы, атап айтқанда мониезиоздың таралуы болып табылады. Мақалада Алматы облысы аймағында қой мониезиозын зерттеу және қой шаруашылығында кездесетін гельминттердің түрлерін анықтау нәтижелері берілген. Зерттеу жұмыстары күзгі кезеңде жүргізілді және  «Нұрай» жеке шаруашылығында 40 бас малдың нәжіс сынамалары зерттелінді. Сынамаларды Дарлинг, Фюллебон және Г.А. Котельников және В.М. Хренов әдістерімен Қазақ Ұлттық аграрлық зерттеу университетінің биологиялық қауіпсіздік кафедрасына қарасты зертханада балау әдістері қойылып, паразиттердің түрлік құрамы, инвазияның қарқындылығы (ИИ) және инвазияның экстенсивтілігі (ИЭ) және паразитоценоз түрлерінің құрамдас бөліктерін зерттедік.
Қойларда кездесетін паразитоздарды копрологиялық әдістермен зерттегенде, аноплоцефалаттар инвазиясы моноинвазиялар және аралас инвазиялар түрінде анықталған. Қойдың ішек-қарын жолында кездесетін паразитоздарды копрологиялық әдістермен зерттеген уақытта 4 гельминт кездесті: Dictyocaulus filarial, Moniezia expansa, Thysaniezia giardi және Avitellina centripunctata.
Айта кету керек, ауруға шалдыққан қойлардың диктиокаулезбен (Dictyocaulus filarial) жалпы залалдануы 12,5% (5 бас) құрады, бір көру аймағында инвазия қарқындылығы 1-ден 14 жұмыртқаға дейін залалданған, ал  Moniezia expansa 40 қойдың 12 бас 30 % залалданған. Сондай-ақ Thysaniezia giardi 8 қой жұқтырды (ИЭ 20,0%, ИИ 1-2 жұмыртқа) және Avitellina centripunctata 2 қой (ИЭ 5,0%, ИИ 1). Осылайша, Moniezia expansa инвазиясының жоғары қарқындылығы байқалды. Инвазия интенсивтілігі жоғары, микроскоптың 1 көру алаңында 1-14 жұмыртқа. Инвазия интенсивтілігі төмен, микроскоптың 1 көру алаңында 1-6 жұмыртқа анықталды.
Values of the Land: Kinships as Climate Solutions in ‘The Honorable Harvest’ and ‘Land as Pedagogy.’
Authors: Morton-Wilcox Abigail
Published: January 2025

Potawatomi scholar Kyle Powys Whyte’s concept of kinship time promotes responses to the climate crisis grounded in kinships and responsibilities. This article explores the land-based relationships and kinships within the essays ‘The Honorable Harvest’ by Potawatomi scholar Robin Wall Kimmerer and the essay ‘Land as Pedagogy’ by Michi Saagiig Nishnaabeg scholar Leanne Betasamosake Simpson in the context of Whyte’s kinship time theory. I centre my analysis of these essays around four values: care, consent, respect, and reciprocity. These values underpin the kinships with the natural world presented by Kimmerer and Simpson and relate to the responsibilities which Whyte identifies as foundational to kinship time. I argue that reading these texts alongside one another reveals the ways in which the kinships with the land presented by Kimmerer and Simpson are integral solutions to the climate crisis. Fundamentally, Kimmerer and Simpson reject and oppose the oppressive and exploitative systems at the centre of the climate emergency: settler colonialism and extractive capitalism, whilst simultaneously providing kinships with the living world as ways of mitigating such crises.

A star's spin–orbit angle can give us insight into a system's formation and dynamical history. In this paper, we use MAROON-X observations of the Rossiter–McLaughlin effect to measure the projected obliquity of the LP 261-75 (also known as TOI-1779) system, focusing on the fully convective M dwarf LP 261-75A and the transiting brown dwarf LP 261-75C. This is the first obliquity constraint of a brown dwarf orbiting an M dwarf and the seventh obliquity constraint of a brown dwarf overall. We measure a projected obliquity of

degrees for the system, meaning that the system is well aligned and that the star is rotating very nearly edge-on, with an inclination of 90° ±  11°. The system thus follows along with the trends observed in transiting brown dwarfs around hotter stars, which typically have low obliquities. The tendency for brown dwarfs to be aligned may point to some enhanced obliquity damping in brown dwarf systems, but there is also a possibility that the LP 261-75 system was simply formed aligned. In addition, we note that the brown dwarf's radius (R

C
 =  0.9 R
J) is not consistent with the youth of the system or radius trends observed in other brown dwarfs, indicating that LP 261-75C may have an unusual formation history.
The Effect of Galaxy Interactions on Starbursts in Milky Way-mass Galaxies in FIRE Simulations

Published: January 2025

Simulations and observations suggest that galaxy interactions may enhance the star formation rate (SFR) in merging galaxies. One proposed mechanism is the torque exerted on the gas and stars in the larger galaxy by the smaller galaxy. We analyze the interaction torques and star formation activity on six galaxies from the FIRE-2 simulation suite with masses comparable to the Milky Way galaxy at redshift z = 0. We trace the halos from z = 3.6 to z = 0, calculating the torque exerted by the nearby galaxies on the gas in the central galaxy. We calculate the correlation between the torque and the SFR across the simulations for various mass ratios. For near-equal-stellar-mass-ratio interactions in the galaxy sample, occurring between z = 1.2−3.6, there is a positive and statistically significant correlation between the torque from nearby galaxies on the gas of the central galaxies and the SFR. For all other samples, no statistically significant correlation is found between the torque and the SFR. Our analysis shows that some, but not all, major interactions cause starbursts in the simulated Milky Way-mass galaxies, and that most starbursts are not caused by galaxy interactions. The transition from “bursty” at high redshift (z ≳ 1) to “steady” star formation state at later times is independent of the interaction history of the galaxies, and most of the interactions do not leave significant imprints on the overall trend of the star formation history of the galaxies.
On the Existence of Long-period Decayless Oscillations in Short Active Region Loops

Published: January 2025

Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (<50 s) decayless oscillations have been detected in short loops (< 50 Mm) within active regions. Nevertheless, long-period decayless oscillations in these loops remain relatively unexplored and crucial for understanding the wave modes and excitation mechanisms of decayless oscillations. We present the statistical analysis of decayless oscillations from two active regions observed by the Extreme Ultraviolet Imager onboard Solar Orbiter. The average loop length and period of the detected oscillations are 19 Mm and 151 s, respectively. We find 82 long-period and 23 short-period oscillations in these loops. We do not obtain a significant correlation between loop length and period. We discuss the possibility of different wave modes in short loops, although standing waves cannot be excluded from possible wave modes. Furthermore, a different branch exists for active region short loops in the loop length versus period relation, similar to decayless waves in short loops in the quiet Sun and coronal holes. The magnetic fields derived from MHD seismology, based on standing kink modes, show lower values for multiple oscillations compared to previous estimates for long loops in active regions. Additionally, the comparison of period distributions in short loops across different coronal regions indicates that different excitation mechanisms may trigger short-period kink oscillations in active regions compared to the quiet Sun and coronal holes.
A uGMRT and MeerKAT Study of Radio Relics in the Low-mass Merging Cluster PSZ2 G200.95−28.16
Authors: Pal Arpan , Kale Ruta , Wang Qian H. S. , Wik Daniel R.
Published: January 2025

Diffuse radio sources known as radio relics are direct tracers of shocks in the outskirts of merging galaxy clusters. PSZ2 G200.95–28.16, a low-mass merging cluster (M
500 = (2.7 ± 0.2) × 1014
M
⊙), features a prominent radio relic, first identified by R. Kale et al. We name this relic as the Seahorse. The MeerKAT Galaxy Cluster Legacy Survey has confirmed two additional radio relics, R2 and R3, in this cluster. We present new observations of this cluster with the upgraded Giant Metrewave Radio Telescope (uGMRT) at 400 and 650 MHz, paired with Chandra X-ray data. The largest linear sizes for the three relics are 1.53 Mpc, 1.12 kpc, and 340 kpc. All three radio relics are polarized at 1283 MHz. Assuming the diffusive shock acceleration model, the spectral indices of the relics imply shock Mach Numbers of 3.1 ± 0.8 and 2.8 ± 0.9 for the Seahorse and R2, respectively. The Chandra X-ray surface brightness map shows two prominent subclusters, but the relics are not perpendicular to the likely merger axis, as typically observed; no shocks are detected at the locations of the relics. We discuss possible merger scenarios in light of the low mass of the cluster and the radio and X-ray properties of the relics. The relic R2 follows the correlation known in the radio relic power and cluster-mass plane, but the Seahorse and R3 relics are outliers. We have also discovered a radio ring in our 650 MHz uGMRT image that could be an Odd Radio Circle candidate.
The Blue Lurker WOCS 14020: A Long-period Post-common-envelope Binary in M67 Originating from a Merger in a Triple System

We present Hubble Space Telescope far-ultraviolet (FUV) spectra of a blue lurker–white dwarf (BL–WD) binary system in the 4 Gyr open cluster M67. We fit the FUV spectrum of the WD, determining it is a C/O WD with a mass of

M
⊙ and a cooling age of ~400 Myr. This requires a WD progenitor of ~3 M
⊙, significantly larger than the current cluster turnoff mass of 1.3 M
⊙. We suggest the WD progenitor star formed several hundred megayears ago via the merger of two stars near the turnoff of the cluster. In this scenario, the original progenitor system was a hierarchical triple consisting of a close, near-equal-mass inner binary, with a tertiary companion with an orbit of a few thousand days. The WD is descended from the merged inner binary, and the original tertiary is now the observed BL. The likely formation scenario involves a common envelope while the WD progenitor is on the AGB, and thus the observed orbital period of 359 days requires an efficient common envelope ejection. The rapid rotation of the BL indicates it accreted some material during its evolution, perhaps via a wind prior to the common envelope. This system will likely undergo a second common envelope in the future and thus could result in a short-period double WD binary or merger of a 0.72 M
⊙ C/O WD and a 0.38 M

We present JWST Near Infrared Spectrograph (NIRSpec) measurements of the three largest low-albedo main-belt asteroids: (1) Ceres, (2) Pallas, and (10) Hygiea. Their reflectance spectra all have very similar absorptions centered near 2.72 μm attributed to Mg–OH in minerals. Within this band, Pallas also shows evidence of a sharper, deeper band, also centered near 2.72 μm. These band positions are similar to those seen in the most aqueously altered carbonaceous chondrites and samples from Ryugu and Bennu. Absorptions in the 2.7–2.9 μm region due to other cation–OH combinations are weak, if present. The NIRSpec spectrum of Ceres is consistent with the global average spectrum of Dawn, and the similarity between Ceres and Hygiea seen in other wavelength regions continues into the 2.5–2.8 μm region. This similarity in spectral properties, and thus in interpretations of surface composition, implies that the two bodies may have had similar processes occur and similar histories. This suggests that Hygiea, similar to Ceres, may be associated with the “ocean worlds” despite its relatively small mass. Quantitative estimates of the hydrogen concentrations on the surfaces suggest hydrogen concentrations of roughly 0.5–1 wt%, consistent with CM chondrites. Additional absorptions attributed to ammoniated minerals are seen in Ceres’s and Hygiea’s spectra, as has been reported by others, but are not seen in Pallas’s spectrum. Absorptions are also seen in the 2.5–2.7 μm region in all three asteroids, likely due to OH combination bands, and from roughly 3.9 to 4.3 μm in Hygiea, which could be due to carbonates plus an unidentified constituent.
Improved region-based active contour segmentation through divergence and convolution techniques
Authors: Shi Ming , Hussain Ibrar
Published: January 2025

In this paper, we present a novel approach to improve the robustness of region-based active contour models for image segmentation, particularly in the presence of noise. Traditional active contour methods often struggle with noise sensitivity and intensity variations within the image. To overcome these limitations, we propose an enhanced segmentation model that integrates the average convolution with entropy-based mean gray level values. Our method leverages the local statistical information by introducing a local similarity factor and local region relative entropy to build a robust energy functional. This energy functional balances the intensity differences between neighboring pixels and regions within the local window, while reducing the impact of noise. By incorporating convolution and entropy into the energy formulation, our model distinguishes between the interior and exterior regions of an image more effectively, thus leading to more accurate segmentation results. We demonstrate the numerical implementation of the proposed model, along with its convexity properties, to ensure stability and reliability. The experimental results show that our method significantly improves the segmentation performance, even in challenging scenarios with varying noise levels. This advancement has the potential to improve image analyses in fields such as medical imaging, object detection, and texture classification.
Single wave solutions of the fractional Landau-Ginzburg-Higgs equation in space-time with accuracy via the beta derivative and mEDAM approach
Authors: Ullah Ikram , Bilal Muhammad , Iqbal Javed , Bulut Hasan , Turk Funda
Published: January 2025

The nonlinear wave behavior in the tropical and mid-latitude troposphere has been simulated using the space-time fractional Landau-Ginzburg-Higgs model. These waves are the consequence of interactions between equatorial and mid-latitude waves, fluid flow in dynamic systems, weak scattering, and extended linkages. The mEDAM method has been used to obtain new and extended closed-form solitary wave solutions of the previously published nonlinear fractional partial differential equation via the beta derivative. A wave transformation converts the fractional-order equation into an ordinary differential equation. Several soliton, single, kink, double, triple, anti-kink, and other soliton types are examples of known conventional wave shapes. The answers are displayed using the latest Python code, which enhances the usage of 2D and 3D plotlines, as well as contour plotlines, to emphasise the tangible utility of the solutions. The results of the study are clear, flexible, and easier to replicate.

Integration of Mobile Interaction Technology in the Tourism Industry and Its Impact on Tourism Consumption Patterns
Authors: Jin Huihui
Published: January 2025

The introduction of mobile interaction technology has fundamentally transformed the delivery of tourism services, enabling travelers to access real-time information, engage in online interactions, and enjoy personalized services through smart devices. This innovative consumption model not only enhances tourist engagement and satisfaction but also drives innovation and transformation in the tourism industry. However, despite existing studies exploring the impact of technology on tourism, most research focuses primarily on the technology itself, lacking a systematic analysis of its deeper implications for reshaping consumption patterns, enhancing industry resilience, and addressing market uncertainties. Current studies are predominantly centered on applications related to big data and consumer behavior analysis, often overlooking how to measure the resilience of tourism consumption patterns through specific indicators and failing to investigate the long-term sustainability of consumption models transformed by interactive technologies. To address these research gaps, this study introduces a novel perspective by constructing a mobile interaction network model, defining resilience indicators for tourism consumption patterns, and systematically evaluating them using a comprehensive assessment approach. This study aims to provide a new theoretical framework for the digital transformation of the tourism industry and practical guidance for enhancing industry resilience and improving risk resistance capabilities.
Les grammaires italiennes dans la deuxième moitié du xixe siècle : entre théorie(s), histoire et société
Authors: Stancati Claudia
Published: January 2025

L’auteure présente une esquisse historique des grammaires de
l’italien entre le moment de l’unification nationale (1861) et le début du xxe siècle afin de vérifier la
présence de différentes orientations théoriques et les liens de la recherche
linguistique italienne avec les diverses écoles européennes. Les textes
scientifiques montrent que l’italien présente plus d’une spécificité par rapport
aux langues romanes. En effet, il est considéré comme la langue la plus proche
du latin ; le nombre et le poids de ses dialectes, également pratiqués par les
personnes instruites, sont remarquables ; enfin, la langue écrite et la langue
littéraire sont davantage considérées que la langue parlée, cela en raison d’une
division politique vieille de plusieurs siècles. Dans un pays qui, pour la
première fois de son histoire, cherche enfin à bâtir une institution scolaire
nationale, tous ces nœuds théoriques influencent aussi les grammaires scolaires.
Ils répondent à la nécessité sociale et politique de traduire la questione della lingua en une didactique capable
d’enseigner la langue nationale à des usagers dialectophones dont la pratique
langagière est souvent très éloignée de cette langue commune qui vient d’être
fixée au prix de grandes discussions.
From Historical to Synchronic Linguistics in Greece: The Critical Decade of 1970s in Its Socio-Historical and Ideological Context
Authors: Giannaris Thanasis , Intzidis Evangelos , Karantzola Eleni
Published: January 2025

Cet article est consacré à l’étude de l’introduction de la linguistique synchronique en Grèce dans les années 1970 et de la réorganisation de la discipline dans les universités grecques. En s’appuyant sur des sources jusqu’à présent peu étudiées (archives universitaires, annuaires, programmes d’étude, etc.) ainsi que sur des entretiens que nous avons conduits, nous décrivons en détail le passage de la linguistique historique à la linguistique synchronique. Nous soutenons, en outre, que ce changement a été influencé par les conditions socio-historiques et les idéologies qui prévalaient au cours de cette période. Enfin, étant donné qu’en 1976 la « question de la langue » est résolue, nous explorons comment la réorientation de la linguistique grecque vers l’état actuel du grec moderne interagit avec les idéologies langagières robustes des deux universités principales (d’Athènes et de Thessalonique).
Wüster/Carnap: Vienna School/Vienna Circle
Authors: Savatovsky Dan
Published: January 2025

Cette contribution vise à mettre en évidence certaines des affinités théoriques entre la terminologie wüstérienne et la philosophie du langage du positivisme logique. Après avoir succinctement indiqué les raisons pour lesquelles la plupart des linguistes du vingtième siècle ont été réticents à « recevoir » la théorie de Wüster en raison de ses présupposés philosophiques, on s’efforce d’étudier quelques-uns de ces présupposés en mettant en regard les conceptions de l’école de Vienne de terminologie et celles du Cercle de Vienne (de Carnap, principalement). On examine tour à tour le recours au principe de parcimonie, la question du nominalisme et le problème de la définition réelle. On termine sur les conditions d’une culture matérielle, telles qu’elles se dégagent d’une terminologie/ontologie des objets techniques à la Wüster.
La Linguistic Society of America et ses effets sur la pratique de la linguistique aux États-Unis
Authors: Newmeyer Frederick J.
Published: January 2025

Cet article se propose de comprendre comment la pratique des linguistes américains a été influencée au fil des ans par les traditions institutionnelles présentes aux États-Unis, en particulier par la politique de l’organisation principale du domaine, la Linguistic Society of America (LSA). Pendant les quinze premières années d’existence de la LSA, une lutte constante a eu lieu entre les défenseurs d’une conception de la linguistique comme science pure et les défenseurs d’une approche liée à la littérature et à la culture. Au début des années 1940, grâce aux efforts concertés de Leonard Bloomfield, Edward Sapir, et d’autres, les linguistes « scientifiques » ont gagné.
Les débuts de la Société pour l’étude des langues romanes de Montpellier
Authors: Boutan Pierre
Published: January 2025

Sur un sujet déjà l’objet de nombreux travaux, l’article vise à en faire une synthèse. Il utilise quelques éléments nouveaux, qui confirment l’originalité de la Société pour l’étude des langues romanes de Montpellier. Malgré les réticences d’une bonne partie des cercles savants parisiens, traitant de haut des érudits provinciaux, ses thèses finiront par s’imposer dans le paysage scientifique, en étant à l’origine des études dialectologiques contemporaines. Les soutiens locaux, la liaison avec le Félibrige et Mistral, peuvent expliquer sa pérennité. Mais il faut essentiellement souligner l’ardeur et la constance de ses fondateurs, autour des figures centrales d’Anatole Boucherie, de Camille Chabaneau et de Charles de Tourtoulon.
Eine evolutionäre Deutung der Theorie der Terminologie von Wüster
Authors: Oeser Erhard
Published: January 2025

In diesem Aufsatz wird eine Verbindung hergestellt zwischen Eugen Wüsters Begriffstheorie und sein semiotisches Wortmodell auf der einen Seite mit der evolutionären und neurobiologischen Kognitionstheorie sowie mit der Evolutionären Erkenntnistheorie der Geschichte der menschlichen Kultur, der Kommunikation und der wissenschaftlichen Theorien. Eine solche evolutionäre Erklärung und Rekonstruktion der Allgemeinen Terminologielehre kann Wüsters Hypothese rechtfertigen, wonach allgemeine Begriffe als Denkeinheiten autonom und unabhängig sind von Wörtern, Zeichen und Benennungen als Kommunikationseinheiten, und diese Rekonstruktion verwandelt sein vierteiliges Wortmodell zusammen mit seiner Unterscheidung zwischen deskriptiver und präskriptiver Terminologiearbeit in ein wirkmächtiges Modell einer kontrollierten Begriffsdynamik.
Les réseaux du style : une double méprise
Authors: Jollin-Bertocchi Sophie , Saint-Gerand Jacques-Philippe
Published: January 2025

La réflexion sur le style comme expression spirituelle de l’art d’écrire développée en Allemagne à la fin du xviiie siècle, à laquelle renvoie le terme Stilistik, a été dévoyée en français sous la dénomination trompeuse de stylistique, qui – faux-ami – accrédite une conception matérialiste de l’application de procédés rhétoriques et grammaticaux. L’objectif du présent article est de montrer pourquoi et comment cette consciente méprise initiale a engendré au sein même de l’Université française des dernières décennies une seconde équivoque plus insidieuse au sujet de l’objet du style. Les travaux de Spitzer, Bally, Bruneau, Cressot, Riffaterre, Eco, Molinié, Bordas, Macé, montrent la nécessité de distinguer entre étude(s) de style et stylistique, mais cette dernière, devenue épreuve imposée des concours de recrutement de l’enseignement secondaire, a vu se démultiplier la publication d’innombrables manuels d’application aux fondements théoriques – grammaticaux, rhétoriques, linguistiques – largement hétérogènes. Ces ouvrages, que justifie la nécessité d’occuper une place du marché éditorial, ne concourent guère à l’approfondissement épistémique du style, notion susceptible de s’appliquer – hors de l’écriture – à bien des secteurs des activités humaines et des pratiques artistiques, mais manifestent l’existence d’un réseau d’intérêts pratiques et économiques dont la recherche ne tire malheureusement aucun bénéfice.
« Faire école » en grammaire : aperçu des données sanskrites (2)
Authors: Aussant Émilie
Published: January 2025

Cet article présente les données relatives aux écoles de grammaire sanskrite de l’Inde pré-moderne recueillies dans plusieurs sources primaires et secondaires, en les articulant à deux questions centrales : 1) que faut-il pour « faire école » ? et 2) sur quels critères se fonde-t-on pour distinguer une école d’une autre ? L’étude montre que c’est principalement autour de ce qui fait (ou non) autorité que le débat se cristallise et que l’affiliation à une école de grammaire se décrète, que l’agent du décret soit l’auteur lui-même, ses disciples ou ses opposants.
L’occupation française de l’Autriche, 1945-1955 : état des lieux historiographique
Authors: Vincent Marie-Bénédicte
Published: January 2025

La zone d’occupation française en Autriche a été moins étudiée comparativement que son homologue en Allemagne. L’article présente un essai de bilan historiographique. Ce faisant, il interroge la spécificité du Tyrol et du Vorarlberg d’une part par rapport à la zone française en Allemagne (qui mobilise plus de personnel mais aussi plus de moyens), d’autre part par rapport aux autres zones d’occupation occidentales en Autriche : dans quelle mesure les Français se sont-ils particulièrement investis dans le champ culturel ? La mémoire collective de la période 1945-1955 est aussi abordée : pourquoi est-elle peu présente tant en France qu’en Autriche aujourd’hui ?
Assessment of Depression and Quality of Life among Elderly in a Rural Area of Goa, India
Authors: Mendes Jennifer , Shah Hemangini K
Published: January 2025

Background:

By 2025, disability-adjusted life years attributable to depression are projected to rise by about 2.6 million (22.5%) due to population growth and aging. Assessing depression and analyzing the quality of life (QoL) among this vulnerable population are vital so that necessary measures to promote healthy aging can be implemented at the community level. Hence, our study was proposed to estimate the prevalence of depression and assess associated factors and QoL among the rural elderly population.

Materials and Methods:

A cross-sectional study was conducted among the elderly population of a rural area in Goa, India, over 1 year. Data were collected using a semi-structured questionnaire, including sociodemographic details, lifestyle factors, and medical history. Depression and QoL were assessed using the Geriatric Depression Scale-15 and short form-12 scale, respectively. Data were analyzed using SPSS version 22.

Results:

The total number of participants enrolled in the study was 384, of which majority, 60.2%, were in the age group of 60–69 years. The prevalence of depression in the current study was 29.2%. There was a statistically significant association between depression and the following variables: sex, self-reported insomnia, marital status, presence of major stressors, living arrangement, and physical activity. Among the study participants, 35.2% and 21.6% had low (<50) physical component summary and mental component summary scores, respectively. The association of depression and QoL was found to be statistically significant.

Conclusion:

Recognizing depressive symptoms among the elderly at an early stage is crucial for managing depression and providing timely remedial measures to improve their QoL.
