Foreclosure on a Share in the Ownership of Real Estate if the Creditor and Co-Owner Coincide in one Person
Authors:   Far Eastern Branch, Russian State University of Justice, Khabarovsk, Russia, Pevtsova Irina E. , Litovchenko Tatyana A.
Published: April 2024

This study is devoted to the specifics of foreclosure on a share in the ownership of real estate in situations where the creditor is simultaneously a co-owner of a share in the right to this property, and accordingly has a preferential right to purchase the debtor's share. Some issues still remain unresolved at the legislative level, which causes difficulties in considering cases of this category. In judicial practice, there is no unified approach to the methodology for determining the market value of the share in the ownership right to which foreclosure is taking place. It is unclear how the plaintiff's demands for foreclosure on the debtor's share should sound with recognition of ownership of the share for the recoverer in terms of payment of funds by the plaintiff to the defendant. The authors propose to change the procedure for foreclosing on a share in the ownership of a real estate object if the co-owner and the recoverer coincide in one person: foreclosure will be carried out through bidding, after determining the winner, co-owners will be offered to purchase a share at a price determined as a result of bidding. This procedure will allow you to determine the actual market value of the share for which foreclosure is taking place, while respecting the pre-emptive right of purchase.
The Рrocedural and Legal Nature of the Competition of Claims
Authors:   Russian State University of Justice, Moscow, Russia, Poskrebnev Maksim E.
Published: April 2024

In the article, the author examined the main features of competition of claims in order to identify their procedural and legal nature. To achieve this goal, the author mainly used the historical method, as well as methods of comparison and analysis. As a result of the study, the author formulated general conclusions that are placed in the conclusion: 1) although competition begins with the choice of a method of defense, its final formalization lies in the concept of a claim addressed to the court, which must select a competing claim, i. e., qualify an offense; 2) the common purpose of competing claims lies in the factual basis of the claim, in circumstances that are the same for the competing claims. However, the unifying feature of competition claims does not include a legal component. It is different for competing claims and stems from different norms of civil law, and therefore entails confrontation between these claims; 3) the termination of other competing claims by the award of the first claim is a key feature of the competition of the claim, indicating the procedural and legal nature of the competition.

Authors:   Korea Real Estate Society, Yoo Jong Kiun , Kim Chan Ho , Lee Chang Soo
Published: April 2024

This study aimed to analyze the similarities and differences in retirement location preferences among Baby Boomers, Generation X, and the Echo Generation. An empirical analysis was conducted on 211 residents of the Seoul metropolitan area for this purpose. The findings revealed that, regardless of generation, the most preferred area for retirement housing were small and medium-sized cities in Gyeonggi-do. Additionally, Baby Boomers and Generation X preferred large cities in Gyeonggi-do, whereas the Echo Generation favored Seoul. Residents of Seoul, irrespective of their generation, showed a strong preference for Seoul, followed by large cities in Gyeonggi-do for Generation X and small to medium-sized cities in Gyeonggi-do for the Echo Generation. Those living in Gyeonggi-do, regardless of their generation, also preferred smaller cities within the region, followed by the larger cities. Among individuals wishing to reside in the metropolitan area post-retirement, the eastern and southern regions of Gyeonggi were the most favored areas across all generations. Regarding the type of area they preferred to move to after retirement, Baby Boomers had a preference for purely urban areas, while Generation X showed a preference for a combination of urban and rural areas. The Echo Generation, on the other hand, exhibited similar preferences for mixed urban and rural areas and purely urban areas. On the other hand, in the case of the echo generation, preferences for mixed urban and rural areas and urban areas were similar. In terms of selecting a post-retirement residence, transportation access was the top priority for Baby Boomers and Generation X, whereas living convenience was paramount for the Echo Generation. The study concluded with academic and practical implications based on these findings.

Published: April 2024

The purpose of this study is to make a model to forecasting apartment trade price and household rent price in apartment housing market using ARIMA model. On the basis of those models, I tried to forecast the fluctuations of short-term apartment trade price and household rent price in Seoul apartment market. To analyze the ARIMA model, quarterly data during 2011 1/4∼2023 4/4 are used for identification, estimation, diagnosis, and prediction of the ARIMA model. Using ARIMA model, the outcome ARIMA(1,1,0) model is applied to Sepol apartment trade price in the rate of apartment trade price forecasting model, and ARIMA(1,1,1) model is applied to Seoul apartment household rent price in the rate of apartment rent price. According to the forecast results of Seoul apartment trade price and apartment household rent price in the ARIMA model, looking at the quarterly rate of change in Seoul apartment sales prices, it appears that they will continue to go up the 2024 1/4, and will continue to rise but without significant fluctuations. Looking at the quarterly trend of Seoul apartment rental prices on the 2024 1/4 and continue until the 2024 4/4, and the upward trend will be larger than Seoul apt sale price. While the government's housing policy is sluggish, Seoul apartment sales prices and Jeonse prices are expected to be affected by a decrease in apartment supply and interest rates due to a decrease in permits and occupancy this year.

Authors:   Korea Real Estate Society, Jun han bo me , Koo ja hoon
Published: April 2024

It will be useful information to analyze using past housing market’s data can be predicted future direction. It will be very interesting information for market participants if the direction of prices and transaction volume can be predicted. Therefore, the purpose of this study is to identify the housing circulation phase by dividing it by period, focusing on the Seoul housing market, which is the center of price fluctuations in the current housing market, and to compare and analyze the correlation between housing prices and trading in each circulation phase. To analyze the correlation between the two variables, Granger causality test, vector autoregression model (VAR), and impulse response analysis were used. As a result of the study, the housing circulation phase is subdivided into four phases, and the direction of prices and transaction volume is analyzed differently for each phase. There is a positive correlation between price and trading and prices affect transaction volume in the short term, but the influence of transaction volume on prices is insignificant. However, it has been proven that one of the two variables has predictive power for the other. Although there is a limitation in that it is not possible to analyze the direct factors affecting the variables, it is believed that it can be used as useful information for housing participants and government policy officials.
A Study on the User Satisfaction with Information on Real Estate Brokerage Platforms: Applying the Expectancy-Disconfirmation Theory
Authors:   Korea Real Estate Society, Hyun Chang Ho , Kim Ji Hyun
Published: April 2024

This study examines how user expectation influence satisfaction on real estate brokerage platforms applying the expectancy-disconfirmation theory. It operationalized and measured variables such as user expectations, perceived performance, expectancy-discrepancy, satisfaction, and subsequent behavioral intentions based on prior research. Hypotheses were developed for empirical analysis, and data from 272 responses collected via a 5-point likert scale survey were analyzed. Structural equation modeling(SEM) was employed to validate relationships among variables and analyze direct and indirect effects. The results indicate that user expectations significantly affect performance but not expectancy-discrepancy or satisfaction directly. However, expectations indirectly impact satisfaction through expectancydiscrepancy, acting as a criterion for satisfaction before direct user experience. Performance influences expectancy-discrepancy but not satisfaction directly. Expectancy-discrepancy positively influences satisfaction, leading to subsequent behavioral intentions like revisiting or recommending the platform. In summary, although user expectations do not directly influence satisfaction, their indirect effect through expectancy-discrepancy underscores the dynamic interplay between expectations and satisfaction.
Beyond the Marketing Hype: Analysis of Communication Campaigns of Electric Vehicles Eco-Friendly Image and Battery Waste Concerns
Authors: Putra Aziz Sandy , Fatimah Yasmin Zein  , Rizal B. D. Herdian
Published: April 2024

Electric Vehicles (EVs) are gaining widespread attention for their environmentally friendly nature and potential to reduce air pollution. As non-renewable fossil fuels deplete, the need for sustainable alternatives like EVs becomes imperative. The EV market emphasizes the cost-effectiveness of electric fuel and extended travel range, despite the initial higher cost of purchasing an EV. In Indonesia, the government encourages EV adoption through subsidies and improved electric refuelling infrastructure, including exempting EV users from the odd-even vehicle license plate rule in Jakarta.

To promote EV adoption, brands employ diverse marketing strategies, urging customers to embrace EVs as agents of environmental change. However, the lack of transparency in how EV brands handle nickel-based battery waste, with a limited lifespan, raises environmental concerns. The accumulation of unusable batteries could pose soil pollution risks as EV usage grows. This research aims to explore the environmental implications of battery waste from EVs in Indonesia and analyze how EV brands address these concerns in their marketing communication campaigns.

Adopting a cybernetic approach, the study examines the interconnectedness of marketing communication and consumer buying decisions. Qualitative research is utilized, drawing on various EV studies, facts about EV brand communication, and interviews with experts to provide a comprehensive analysis. Although battery waste might not be a pressing issue in Indonesia currently, inadequate waste handling raises potential future concerns about soil and water contamination. Addressing battery waste responsibly is crucial for promoting sustainable EV adoption.
Public Relations in a Digital Era: Localising the Global Corporations’ Activities and Social Media Uses in Tanzania
Authors: Mohamed ISSA Hassan
Published: April 2024

Public Relations concepts and practice in different democracies vary according to the nature of their political, cultural, social, and the level of technological orientation or advancement. With the digital age and the increasing trend in globalization, Global or Multinational Corporations have both challenges and opportunities towards meeting their business goals as to win hearts and minds of customers/publics in a diverse environment. Public Relations in Digital Age: Localising Global Corporations Activities and Social Media Uses in Tanzania, using Standard Chartered Bank, Coca Cola Company, and Barrick (Acacia) Mines, as case, has investigated the activities done by the Corporations, social media engagement, Corporate Social Responsibility activities and comparing local and global activities of the Corporations. The three Corporations’ profiles were surveyed to grasp their natures - activities and new media uses while a three- year content analysis was done through Corporations’ social networking sites (SNS) – Facebook, Twitter and You Tube to understand their uses of SNS in enhancing their roles through Public Relations. The findings show that despite their differences in nature, they all use their global business experiences in dealing with local activities. They have been responding to silent calls for glocalisation by identifying the basic needs of their customers/publics, for example, localizing the brand (Coca Cola to Coca Cola Kwanza), changing the brand name altogether (Barrick to Acacia), as well as stretching their Corporate Social Responsibility activities in health, education, environment and sports and entertainment while strengthening their ties with the government by not only responding to legal obligations like paying taxes but also supporting communication and health sectors. However, more glocalisation process is still in need as compared to what has been done in other countries in responding to cultural-centric and polycentric PR approaches. Moreover, the MNCs use both asymmetric and symmetric communication through Facebook, Twitter and You Tube. Twitter has been the mostly used SN especially in a symmetrical communication followed by Facebook. It has been also observed that the sensitivity of Corporation’s activities increases the engagement in CSR activities. Since, the area has not been extensively researched, the researcher calls for more studies on glocalisation of MNCs and new media uses in developing countries and Tanzania in particular in attempt to exploit the potentials of Public Relations.

Authors: Erick Fungameza Edward , Hahmed Salim Salim
Published: April 2024

his study researched on issues influencing performance management of public organizations in Tanzania was done at Medical Store Department (MSD) Headquarter Dar es Salaam and 75 respondents participated. The general objective was to explore issues influencing performance management of public organisations in Tanzania. Specific objectives were; to determine the influence of leadership in the performance of public organisations and to determine the influence of strategic plan in the performance of public organisations. The study used a qualitative research approach and used both primary and secondary data. Primary data collected through key informant interview and secondary data collected through documentary review. The study revealed that organisations which have leaders with good leadership skills, well-structured and cooperative strategic plan are likely to have good performance management. Moreover the study found that good leadership is the major influence of performance management in any organisation. Organisations might have structured and cooperative strategic plan but without having good leaders with high leadership skills it will not work out. Furthermore, the study exposed that there are other issues like motivation and personal attitudes which can influence organization performance management. The study recommends that MSD should have a leaders’ succession plan and conduct several leadership skills trainings so as to empower leaders with important skills to carry out their day to day errands in an effective and efficient manner. Also they have to make sure that their strategic plan is communicated to all level of employees for easy implementation. Not all that but also employees should be motivated and encouraged to have good attitudes which have positive relationship with organisation performance.

THE ROLE OF ADAPTIVE RESILIENCE IN THE RELATIONSHIP BETWEEN TRANSFORMATIONAL LEADERSHIP, AFFECTIVE COMMITMENT AND TURNOVER INTENTION IN THE POST COVID-19 ERA: A CASE OF VIETNAM
Authors: Ha Minh Thi Phuong , Ho Dung Tien , Nguyen Long Ngoc
Published: April 2024

This study investigates the direct or indirect impact of transformational leadership and adaptive resilience on affective commitment and turnover intention. Qualitative research was conducted to validate the concepts and the research model and quantitative research was carried out to analyze data from 310 employees selected via convenient sampling in Vietnam. The results reveal that transformational leadership does not only directly affect adaptive resilience and turnover intention, but also indirectly and fully affects affective commitment via adaptive resilience, and indirectly and partially affects turnover intention via affective commitment and adaptive resilience. Furthermore, adaptive resilience significantly impacts turnover intention via affective commitment. There is no proof in the research that adaptive resilience directly affects turnover intention. This research has documented valuable experiences related to the adaptive resilience of organizations following social crises in the relationship between leadership and turnover for scholars and managers in the future.

⊙

and a half-light radius of 3 ± 1 pc, it is either the darkest galaxy ever discovered or the faintest self-gravitating star cluster known to orbit the Galaxy. Its line-of-sight velocity dispersion suggests the presence of dark matter, although current measurements are inconclusive because of the unknown contribution to the dispersion of potential binary stars. We use N-body simulations to show that, if self-gravitating, the system could not survive in the Milky Way tidal field for much longer than a single orbit (roughly 0.4 Gyr), which strongly suggests that the system is stabilized by the presence of large amounts of dark matter. If UMa3/U1 formed at the center of a ∼109
M
⊙ cuspy LCDM halo, its velocity dispersion would be predicted to be of order ∼1 km s−1. This is roughly consistent with the current estimate, which, neglecting binaries, places σ
los in the range 1–4 km s−1. Because of its dense cusp, such a halo should be able to survive the Milky Way tidal field, keeping UMa3/U1 relatively unscathed until the present time. This implies that UMa3/U1 is plausibly the faintest and densest dwarf galaxy satellite of the Milky Way, with important implications for alternative dark matter models and for the minimum halo mass threshold for luminous galaxy formation in the LCDM cosmology. Our results call for multi-epoch high-resolution spectroscopic follow-up to confirm the dark matter content of this extraordinary system.

Published: April 2024

The far-infrared (FIR) opacity of dust in dark clouds within the Ophiuchus molecular cloud is investigated through multiwavelength infrared observations from UKIDSS, Spitzer, and Herschel. Employing the infrared color excess technique with both near-infrared and mid-infrared photometric data, a high-resolution extinction map in the K band (A

K
) is constructed for three dark clouds: L1689, L1709, and L1712. The derived extinction map has a resolution of

and reaches a depth of A

K
∼ 3 mag. The FIR optical depths τ
250 at a reference wavelength of 250 μm are obtained by fitting the Herschel PACS and SPIRE continuum data at 100, 160, 250, 350, and 500 μm using a modified blackbody model. The average dust opacity per unit gas mass at 250 μm, r
κ
250, is determined through a pixel-by-pixel correlation of τ
250 with A

K
, yielding a value of approximately 0.09 cm2 g−1, which is about 2–3 times higher than the typical value in the diffuse interstellar medium. Additionally, an independent analysis across 16 subregions within the Ophiuchus cloud indicates spatial variations in dust opacity, with values ranging from 0.07 to 0.12 cm2 g−1. Although the observed trend of increasing dust opacity with higher extinction implies grain growth, our findings indicate that rapid grain growth has clearly not yet occurred in the dark clouds studied in this work.
Giant Biconical Dust Filaments in the Starburst Galaxy NGC 1808
Authors: Kane Rohan , Veilleux Sylvain
Published: April 2024

We present the results from an analysis of multiwavelength archival data on the multiphase outflow in the starburst galaxy NGC 1808. We report the detection at 70 and 100 μm of dust filaments that extend up to ∼13 kpc from the galactic midplane and trace an edge-brightened biconical structure along the minor axis of the galaxy. The inner filaments are roughly cospatial with previously identified optical dust filaments, extraplanar polycyclic aromatic hydrocarbon emission, and neutral and ionized gaseous outflows. The 70/160 μm flux ratio, a proxy for the dust temperature, is elevated along the edges of the cones, indicating that the dusty medium has been driven out of the central regions of these cones and is possibly shock-heated by a large-scale outflow. We establish lower limits on the extraplanar dust mass and mean height above the stellar disk of

and ∣ z ∣ ∼ 5 kpc. The energy requirement of (5.1–9.6) × 1056 erg needed to lift the dusty material, assuming a Milky Way–like dust-to-gas ratio, can be supplied by the current starburst, with a measured star formation rate of 3.5–5.4 M

Published: April 2024

In this Letter, we examine the relationship between 3D magnetic free energy (MFE) and flaring activity using 83 major solar flares (M-class and X-class) in nine solar active regions (ARs). For this, we use 998 nonlinear force-free field extrapolations compiled by the “Institute for Space-Earth Environmental Research Database” at Nagoya University. These ARs produced at least three major flares with distinct rising and peak phases of 3D MFE. For each phase, the solar flare occurrence rate (FOR) is calculated as a ratio of the number of flares to the duration. The major results from this study are summarized as follows. First, there is no clear linear correlation (CC = 0.15) between 3D MFE and flare peak flux. Second, the FOR (3.4 day−1) of the rising phase is a little higher than that (3.1 day−1) of the peak phase, depending on AR. Third, for several flares, there are noticeable decreases in 3D MFE, which correspond to the typical energy of a major flare (about 1032 erg). Fourth, it is interesting to note that there are noticeable enhancements in FORs at several local maxima of 3D MFE, which may be associated with flux emergence and/or shearing motions. Fifth, the flare index rates, which are defined as the summation of flaring activity divided by the duration, of rising and peak phases are 151 day−1 and 314 day−1, respectively. Our results imply that the traditional and simple “storage and release” model does not apply to flare activities, and the random perturbation may be important for triggering flares.
JWST Near-infrared Spectroscopy of the Lucy Jupiter Trojan Flyby Targets: Evidence for OH Absorption, Aliphatic Organics, and CO2

Published: April 2024

We present observations obtained with the Near Infrared Spectrograph on JWST of the five Jupiter Trojans that will be visited by the Lucy spacecraft—the Patroclus–Menoetius binary, Eurybates, Orus, Leucus, and Polymele. The measured 1.7–5.3 μm reflectance spectra, which provide increased wavelength coverage, spatial resolution, and signal-to-noise ratio over previous ground-based spectroscopy, reveal several distinct absorption features. We detect a broad OH band centered at 3 μm that is most prominent on the less-red objects Eurybates, Patroclus–Menoetius, and Polymele. An additional absorption feature at 3.3–3.6 μm, indicative of aliphatic organics, is systematically deeper on the red objects Orus and Leucus. The collisional fragment Eurybates is unique in displaying an absorption band at 4.25 μm that we attribute to bound or trapped CO2. Comparisons with other solar system small bodies reveal broad similarities in the 2.7–3.6 μm bands with analogous features on Centaurs, Kuiper Belt objects (KBOs), and the active asteroid 238P. In the context of recent solar system evolution models, which posit that the Trojans initially formed in the outer solar system, the significant attenuation of the 2.7–3.6 μm absorption features on Trojans relative to KBOs may be the result of secondary thermal processing of the Trojans’ surfaces at the higher temperatures of the Jupiter region. The CO2 band manifested on the surface of Eurybates suggests that CO2 may be a major constituent in the bulk composition of Trojans, but resides in the subsurface or deeper interior and is largely obscured by refractory material that formed from the thermophysical processes that were activated during their inward migration.
Effects of Adding Dexamethasone Plus Ketamine to Bupivacaine for Ultrasound-guided Serratus Plane Block as Analgesia in Major Breast Surgery: A Randomized, Double-blind Trial
Authors: Bakeer Ahmed Hussein , Abdou Ahmed Fakher , Abdelhaleem Jehan Mohamed , Abdou Doaa Abdeltawab
Published: April 2024

BACKGROUND: Post-operative pain after mastectomy is associated with poor recovery, prolonged hospital stays, and increased liability for chronic persistent pain.
AIM: This work aimed to test the analgesic efficacy of adding ketamine to a dexamethasone bupivacaine combination in ultrasound-guided serratus anterior plane block (SAPB) in patients undergoing modified radical mastectomy (MRM).
METHODS: This randomized, double-blind trial included 60 females aged 20–60 undergoing MRM. They were randomized into two groups: Group DB (n = 30) received SAPB using 30 ml of bupivacaine 0.25% and dexamethasone 4 mg. Group KD (n = 30) received the same block with the addition of ketamine 50 mg.
RESULTS: The time to the first analgesic request was significantly delayed in Group KD than in Group DB (p < 0.001). The number of patients requiring morphine and its total consumption during the first 24 post-operative hours in Group KD were significantly less than in Group DB (p = 0.001 and p < 0.001, respectively). Visual Analog Scale scores at rest and movement at 4, 6, 8, 10, 12, and 18 h were significantly lower in Group KD than in Group DB.
CONCLUSIONS: Adding ketamine to bupivacaine plus dexamethasone in ultrasound-guided SAPB is associated with better analgesic outcomes in patients undergoing MRM, including prolonged duration of analgesia and decreased post-operative morphine consumption and pain scores at rest and movement.

Published: April 2024

Cet article s’appuie sur la littérature relative à l’adoption des nouvelles technologies et sur des études empiriques portant sur l’adoption des médias sociaux dans le secteur public pour analyser le cas des municipalités belges. Notre objectif est triple : (a) proposer une nouvelle approche pour évaluer l’adoption des plateformes de médias sociaux par les gouvernements, (b) décrire la situation en Belgique à travers le concept d’« adoption active » et (c) déterminer les principaux facteurs liés à l’adoption de Facebook dans les communes belges de plus de 10 000 habitants. Pour atteindre ces objectifs, nous avons utilisé un logiciel pour récupérer des données quantitatives concernant l’adoption et l’institutionnalisation de Facebook. Nos résultats révèlent que la taille de la commune, l’âge médian et la longévité sur la plateforme sont positivement associés à l’adoption de Facebook. En revanche, le revenu médian est, étonnamment, associé négativement à plusieurs dimensions de l’adoption active. Ces résultats contribuent à la littérature sur les facteurs liés à l’utilisation des médias sociaux. En outre, les nouvelles façons de comprendre les modèles d’adoption et d’institutionnalisation offrent une approche conceptuelle solide et des pistes intéressantes de recherche. Pour les praticiens, notre étude offre aux municipalités un nouveau modèle d’évaluation de l’adoption des réseaux sociaux, soulignant la différence fondamentale entre l’inscription et « l’adoption active ». Remarques à l’intention des praticiens Cet article propose une nouvelle approche pour évaluer l’adoption des médias sociaux et les modèles d’institutionnalisation dans les organisations publiques. Il offre un cadre d’évaluation de l’adoption des réseaux sociaux, soulignant la différence fondamentale entre l’inscription et « l’adoption active ». Il identifie également les principaux facteurs liés à l’adoption de Facebook dans les communes belges de plus de 10 000 habitants : la taille de la population, l’âge médian, le revenu médian et les variables liées aux réseaux sociaux – c’est-à-dire l’activité sur Twitter et Instagram – ainsi que la longévité sur la plateforme.

De nombreux pays ont adopté diverses mesures pour freiner la propagation de la pandémie de COVID-19. Les mesures réglementaires de confinement ont entraîné des changements dans la confiance politique du public envers le gouvernement (y compris dans sa compétence, sa bienveillance et son intégrité). L’information influence les opinions et les valeurs des résidents ; ce document vise à étudier l’effet d’un confinement sur la confiance politique et l’effet modérateur de la qualité de l’information partagée par le gouvernement. Du 12 mars au 31 mai 2022, Shanghai a mis en place des mesures strictes de confinement. Dans cette étude, nous avons échantillonné au hasard les informations de participation de 1063 participants. L’analyse de régression basée sur les données montre que le confinement a eu un impact négatif sur toutes les sous-catégories de confiance politique. Cependant, les informations opportunes et précises affaiblissent cet effet négatif. L’exactitude de l’information modère la relation entre le confinement et la confiance politique dans la compétence et l’intégrité, tandis qu’une quantité suffisante d’informations modère la relation entre le confinement et la confiance politique dans la bienveillance. Remarques à l’intention des praticiens Cette étude explore comment les différentes dimensions de la qualité de l’information affectent la confiance politique de chaque composante publique, et incite ainsi les praticiens à améliorer stratégiquement la communication de l’information en cas de crise.
Adaptive fractional physical information neural network based on PQI scheme for solving time-fractional partial differential equations
Authors: Yang Ziqing , Niu Ruiping , Chen Miaomiao , Jia Hongen , Li Shengli
Published: April 2024

In this paper, an accurate fractional physical information neural network with an adaptive learning rate (adaptive-fPINN-PQI) was first proposed for solving fractional partial differential equations. First, piecewise quadratic interpolation (PQI) in the sense of the Hadamard finite-part integral was introduced in the neural network to discretize the time-fractional derivative in the Caputo sense. Second, the adaptive learning rate residual network was constructed to keep the network from being stuck in the locally optimal solution, which automatically adjusts the weights of different loss terms, significantly balancing their gradients. Additionally, different from the traditional physical information neural networks, this neural network employs a new composite activation function based on the principle of Fourier transform instead of a single activation function, which significantly enhances the network's accuracy. Finally, numerous time-fractional diffusion and time-fractional phase-field equations were solved using the proposed adaptive-fPINN-PQI to demonstrate its high precision and efficiency.
FAGRec: Alleviating data sparsity in POI recommendations via the feature-aware graph learning
Authors: Liu Xia , Wu Liwan
Published: April 2024

Point-of-interest (POI) recommendation has attracted great attention in the field of recommender systems over the past decade. Various techniques, such as those based on matrix factorization and deep neural networks, have demonstrated outstanding performance. However, these methods are susceptible to the impact of data sparsity. Data sparsity is a significant characteristic of POI recommendation, where some POIs have limited interaction records and, in extreme cases, become cold-start POIs with no interaction history. To alleviate the influence of data sparsity on model performance, this paper introduced FAGRec, a POI-recommendation model based on the feature-aware graph. The key idea was to construct an interaction graph between POIs and their initial features. This allows the transformation of POI features into a weighted aggregation of initial features. Different POIs can share the learned representations of initial features, thereby mitigating the issue of data sparsity. Furthermore, we proposed attention-based graph neural networks and a user preference estimation method based on delayed time factors for learning representations of POIs and users, contributing to the generation of recommendations. Experimental results on two real-world datasets demonstrate the effectiveness of FAGRec in the task of POI recommendation.
Labellisation et fabrique urbaine
Authors: Rotolo Marina
Published: April 2024

Depuis plusieurs années, de plus en plus de villes rivalisent d’ingéniosité pour obtenir le titre de « Capitale européenne de la culture ». Ce label a en effet été synonyme d’un renouveau économique et d’une politique de régénération urbaine pour des villes comme Glasgow (1990), Lille (2004) ou Liverpool (2008). En s’appuyant sur le cas singulier de Matera, ville moyenne d’Italie méridionale doublement labellisée (patrimoine mondial de l’Unesco en 1993 et Capitale européenne de la culture en 2019), cette étude entraîne le lecteur dans les coulisses du processus de labellisation. L’arrière-scène est ici analysée sous un triple aspect : les jeux d’acteurs, les représentations urbaines et les projets de transformation de la ville. Animée par l’envie de « suivre à la trace » les interactions et les jeux de pouvoir à l’œuvre dans ce processus de labellisation, Marina Rotolo propose une approche originale permettant de dépasser les études déjà parues sur le sujet, traditionnellement axées sur l’évaluation des impacts du label culturel. Cet ouvrage richement illustré convoque plusieurs disciplines (architecture, histoire urbaine, anthropologie) et mobilise des sources inédites et variées. Dans une ère définie par la compétition internationale et une concurrence accrue entre les villes, où les métropoles dominent, il questionne plus globalement les effets de la labellisation sur la fabrique urbaine des villes moyennes, à l’image de Bourges, récemment désignée Capitale européenne de la culture 2028.
Pêche à l’hameçon
Authors: Mazet Albane
Published: April 2024

L’étude techno-fonctionnelle d’hameçons en os mésolithiques retrouvés dans les fjords et sur la côte de l’ouest de la Norvège permet de renseigner la pratique de la pêche et son évolution (8 000-4 000 BC). Bien que l’analyse de la chaîne opératoire indique une continuité dans la tradition technique, des hameçons typologiquement différents semblent se succéder au cours du Mésolithique. Les différences morphologiques observées (répartition des volumes, localisation des encoches, dimensions) sont questionnées en couplant une étude statistique morphométrique et une analyse technologique des hameçons. Les transformations observées sur l’outillage sont corrélées à des évolutions dans la pratique de la pêche, avec une intensification de l’exploitation des ressources aquatiques.
Trames urbaines au fil de l’eau
Authors: Houdas Alexandre
Published: April 2024

Au cours du IIIe millénaire av. J.-C., la civilisation de l’Indus est à l’origine de l’apparition et du développement des premières villes d’Asie du Sud. Ces dernières sont notamment caractérisées par de nombreuses structures hydrauliques (puits, salles d’eau, puisards, canalisations, égouts collecteurs et réservoirs) qui sont intégrées dans un tissu urbain planifié. Ces structures s’avèrent souvent mieux préservées que le reste des architectures, majoritairement bâties en brique crue. Par conséquent, leur étude aide les archéologues à restituer les trames urbaines des sites. Enfin, ces aménagements apportent de précieux indices sur la chronologie et le développement des villes tout en éclairant leur organisation spatiale, économique et sociale.
Traverser la péninsule Arabique aux débuts de l’Islam
Authors: Chung-To Guillaume
Published: April 2024

Cet article aborde la question de la gestion de la ressource en eau le long des itinéraires caravaniers de la péninsule Arabique aux débuts de l’Islam et plus particulièrement à partir de la seconde moitié du viiie siècle. S’appuyant principalement sur les données produites dans les années 1980-1990 par des chercheurs saoudiens, il présente les limites de ces approches archéologiques mais également ce qu’elles apportent à notre connaissance des structures hydrauliques le long de ces routes. Cet article explore les aspects fonctionnels de ces haltes dans leur rapport à l’eau, abordant les questions d’approvisionnement, de gestion et de contrôle de l’eau.
Le rôle du réseau hydrique dans le paysage agraire et son exploitation dans les Memnoneia (Louxor, Égypte) à l’époque hellénistique
Authors: Nicatore Giulia
Published: April 2024

Depuis l’Antiquité, la relation de la civilisation égyptienne avec le Nil est mise en avant comme un facteur essentiel dans la formation et le développement de l’État pharaonique. Il existait d’autres voies d’eau en dehors du lit principal du fleuve, utilisées principalement pour la vie quotidienne et l’agriculture. Il est possible de reconnaître dans le paysage actuel, à partir d’images satellites, quelques traces de canaux ou de paléo-bras du Nil. L’analyse papyrologique permet également de visualiser le paléo-paysage. La relecture environnementale d’un groupe de documents démotiques (iiie-ier siècle av. J.-C.), contextualisés dans la campagne des Memnoneia (rive ouest de l’actuelle ville de Louxor) démontre la richesse des éléments topographiques liés à l’eau dans la région. L’analyse des termes démotiques, utilisés pour qualifier les types de terres en relation avec la présence d’eau, témoigne de la perception que les agriculteurs avaient des différents sols.
Évolution de l’eau dans la préfecture des Gaules
Authors: Gentile Ilenia
Published: April 2024

L’eau a été un élément fondamental dans le développement de formes complexes d’agrégation socio-économique chez les premières populations chrétiennes, qui lui ont notamment attribué des propriétés miraculeuses dans la guérison physique et spirituelle. La présente recherche se base sur l’analyse croisée des données issues de sources littéraires et archéologiques. Les textes hagiographiques donnent souvent des informations sommaires sur les événements et sur les lieux mais, malheureusement, il n’est pas toujours facile de trouver une correspondance avec les données archéologiques. En réalité, de nombreuses structures mentionnées dans les sources écrites ont disparu ou ont été réutilisées à des époques postérieures. Cette étude est centrée sur le lien entre eau, santé et guérison dans la société de l’Antiquité tardive de la préfecture des Gaules, dans le contexte de la longue et complexe phase de christianisation.
Redesigning Local Welfare between Social Innovation and Multi-stakeholder Governance: The Case of the Municipality of Parma in Pandemic Times
Authors: Maino Franca , Tommaso Celestina Valeria De
Published: April 2024

To cope with increasing endogenous pressure (e.g., population aging and the emergence of new social risks) and scarce resources, Italian local welfare actors have had to reshuffle their economic, ideational, and human resources to deliver tailor-made responses to a wider range of beneficiaries through co-management. The Covid-19 pandemic further enabled the processes mentioned above. It contributed to a catalyzation of solutions from local hybrid organizations (a “welfare mix” or “collaborative governance”) to cope with the disruptive socio-economic consequences of the crisis and to foster social innovation processes. Considering these transformations, this article addresses the following research question: How have public actors strengthened their capacity to foster policy change through innovative and collaborative processes? This research aims to analyze the development of policy change at a local level with a view to carrying out an in-depth analysis of policy adaptation dynamics.
