This study provides an innovative collaborative spatial decision support system (SDSS) that aims to ensure an equitable spatial distribution of healthcare services. Evaluating the equality of access to health services across different geographical areas is important, as it requires the analysis of various criteria such as the proximity of health centres and hospitals (HCHs), the quality of services offered, connectivity to primary roads, the availability of public transportation hubs, and the density and distribution patterns of HCHs. This purpose is accomplished via the use of geographic information systems (GIS) and multi-criteria decision analysis (MCDA) methods. The proposed model includes the weights of the criteria, which are determined through the ordered weighted average (OWA) and evaluated based on their ORness, which ranges from 0 to 1. Furthermore, this model is improved by the best–worst fuzzy method (F-BWM). This approach produces a spatial map that clearly shows the equity of healthcare systems in urban environments. The findings show that the maximum score observed in this study was 0.38% (with an ORness value of 1), whilst the minimum score recorded was 0.28%. In the most severe scenario (ORness = 0), over 70% of the region shows different degrees of fairness, ranging from moderate to suitable and very suitable conditions. Governments and health authorities can use this information strategically to allocate resources and address inequities in access to healthcare facilities.
Assessing Wet and Dry Periods Using Standardized Precipitation Index Fractal (SPIF) and Polygons: A Novel Approach
Authors: Şen Zekâi
Published: February 2024

In the open literature, there are numerous studies on the normal and extreme (flood and drought) behavior of wet and dry periods based on the understanding of the standard precipitation index (SPI), which provides a series of categorizations by considering the standard normal (Gaussian) probability distribution function (PDF). The numerical meaning of each categorization assessment is quite lacking in terms of future predictions of wet and dry period duration based on historical records. This paper presents a new approach for calculating possible formations of future wet and dry period durations based on historical records through an effective fractal geometric forecasting approach. The essence of the proposed methodology is based on the number of dry periods (steps) of non-overlapping monthly duration along consecutive broken line paths in the SPI classification for wet and dry period durations. It has been observed that the plot of periods on double logarithmic paper falls along a straight line against the number of such periods, implying a power function, which is the essence of fractal geometry. Extending the empirically derived straight line provides the number of periods that may occur in the future over a range of SPI levels. This methodology is referred to as SPI fractal (SPIF), and the classic SPI classification is converted into SPIF wet and dry polygons, which provide additional information about the drought period number within a valid polygonal area, compared to the classic SPI results. The wet and dry period features of any hydro-meteorology time series are constrained in SPIF polygons. The application of the methodology was carried out on monthly rainfall records on the European side of the Istanbul Florya meteorological station in Turkey.

Published: February 2024

Seawater turbidity is a common water quality indicator measured in situ and estimated from space on a regular basis. However, it is rarely correlated with the inherent optical properties of seawater, which convey information about seawater composition. In this study, we show a simple application of the turbidimeter’s weighting function in the estimation of the backscattering coefficient of a model inorganic suspension in seawater. First, we introduce a method to measure the instrument’s weighting function which describes the sensor’s angular response in terms of scattering angles. The determination of the sensor-specific weighting function led us to characterize its angular sensitivity to the presence of suspended particles. The highest sensitivity for the Seapoint turbidimeter is in the range of 114°–128° (containing 25% of the total signal). Next, we describe the correlations between turbidity and the scattering and backscattering coefficients on the example of the model of inorganic particle suspension using the calculations based on Mie theory. The correlations are analyzed for narrow size fractions of the particle size distribution of silica in the range of 0.59–190 µm. We established that there is a good linear correlation (characterized by the coefficient of determination r2 = 0.979) between the part of the scattering coefficient measured by the turbidimeter and the backscattering coefficient of all size fractions of the model inorganic suspension.

Published: February 2024

The potential environmental impact and increased operational costs associated with the upgrading and renovation of sewage treatment plants are acknowledged. This study employs the upgrading and expansion project of a municipal sewage plant in Dongguan City, Guangdong Province, as a case study. Utilizing the principles and methods of the Life Cycle Assessment (LCA), a comprehensive assessment of the environmental benefits during the upgrading and renovation process of the sewage treatment plant, is conducted and targeted solutions are proposed. The research findings indicate that upgrading and renovating sewage treatment plants can significantly augment the adverse environmental effects of such facilities. Therefore, this study strategically proposes measures such as the utilization of clean energy, sludge resource utilization, and recycled water use as carbon emission reduction pathways. Through calculations, it is demonstrated that the utilization of clean energy and sludge resource can respectively reduce electricity consumption by 12.41% and 59.06%. Concurrently, recycled water use can lead to a reduction of 68.65% in carbon emissions, thereby markedly enhancing positive environmental outcomes.

Published: February 2024

Satellite precipitation products (SPPs) are undeniably subject to uncertainty due to retrieval algorithms and sampling issues. Many research efforts have concentrated on merging SPPs to create high-quality merged precipitation datasets (MPDs) in order to reduce these uncertainties. This study investigates the efficacy of dynamically weighted MPDs in contrast to those using static weights. The analysis focuses on comparing MPDs generated using the “dynamic clustered Bayesian averaging (DCBA)” approach with those utilizing the “regional principal component analysis (RPCA)” under fixed-weight conditions. These MPDs were merged from SPPs and reanalysis precipitation data, including TRMM (Tropical Rainfall Measurement Mission) Multi-satellite Precipitation Analysis (TMPA) 3B42V7, PERSIANN-CDR, CMORPH, and the ERA-Interim reanalysis precipitation data. The performance of these datasets was evaluated in Pakistan’s diverse climatic zones—glacial, humid, arid, and hyper-arid—employing data from 102 rain gauge stations. The effectiveness of the DCBA model was quantified using Theil’s U statistic, demonstrating its superiority over the RPCA model and other individual merging methods in the study area The comparative performances of DCBA and RPCA in these regions, as measured by Theil’s U, are 0.49 to 0.53, 0.38 to 0.45, 0.37 to 0.42, and 0.36 to 0.43 in glacial, humid, arid, and hyper-arid zones, respectively. The evaluation of DCBA and RPCA compared with SPPs at different elevations showed poorer performance at high altitudes (>4000 m). The comparison of MPDs with the best performance of SPP (i.e., TMPA) showed significant improvement of DCBA even at altitudes above 4000 m. The improvements are reported as 49.83% for mean absolute error (MAE), 42.31% for root-mean-square error (RMSE), 27.94% for correlation coefficient (CC), 40.15% for standard deviation (SD), and 13.21% for Theil’s U. Relatively smaller improvements are observed for RPCA at 13.04%, 1.56%, 10.91%, 1.67%, and 5.66% in the above indices, respectively. Overall, this study demonstrated the superiority of DCBA over RPCA with static weight. Therefore, it is strongly recommended to use dynamic variation of weights in the development of MPDs.

Published: February 2024

As one of the most significant disturbance sources in the upper marine environment of the South China Sea, tropical cyclones (typhoons) serve as a typical research subject for investigating the energy transfer process between the ocean and atmosphere. Utilizing satellite remote sensing data and focusing on Typhoon Rey No. 22’s transit event in 2021, this study quantitatively analyzes typhoon-induced energy input through heat pumping and cold suction at both surface and subsurface levels of the ocean. Additionally, it explores the response characteristics and feedback mechanisms of sea surface temperature (SST) and chlorophyll-a concentration (Chl-a) in the South China Sea to typhoon events. The research results show that the SST variation along the typhoon track displayed an asymmetric pattern, with a more pronounced warming on the right side and a cold anomaly lasting for 3–5 days on the left side. The subsurface warm anomaly dominated on the right side, showing a maximum temperature difference of 1.54 °C, whereas Ekman suction-induced upwelling led to cooling effects both at the subsurface and surface level on the left side, resulting in a maximum temperature difference of −3.28 °C. During the typhoon event, there was a significant decrease in sea surface heat flux, reaching 323.36 W/m2, accompanied by corresponding changes in SST due to processes such as upwelling, seawater mixing, and air–sea heat transfer dynamics where anomalies arising from oceanic dynamic processes and exchange through sea surface heat flux contributed equally. Furthermore, strong suction-induced upwelling during the typhoon influenced chlorophyll concentration within the central and western regions of the South China Sea (13.5° N–16.5° N, 111° E–112.5° E), resulting in significant enhancement and reaching its peak value at approximately 0.65 mg/L. The average chlorophyll concentration increased by approximately 0.31 mg/L.

Published: February 2024

The use of various advanced oxidation methods in the treatment of wastewater has become the subject of many studies published in recent years. In particular, it is exceedingly significant to compare these treatment methods for industrial wastewater to reduce environmental effects and optimize plant operations and economics. The present study is the first to deal with the treatability of real epoxy paint wastewater (EPW) using MW- and UV-assisted Fenton processes within an optimization framework. A three-factor, three-level Box–Behnken experimental design combined with response surface methodology (RSM) was conducted for maximizing the chemical oxygen demand (COD) and color removal efficiencies of ultraviolet (UV)/Fenton and microwave (MW)/Fenton processes in the treatment of the real epoxy paint wastewater (EPW, initial COD = 4600 ± 90 mg/L, initial color = 114 ± 4 Pt-Co), based on 15 different experimental runs. Three independent variables (reaction time ranging from 20 to 60 min (UV) and from 5 to 15 min (MW), power ranging from 20 to 40 W (UV) and from 300 to 600 W (MW), and H2O2/Fe2+ ratio ranging from 0.2 to 0.6 (for both UV and MW)) were consecutively coded as A, B, and C at three levels (−1, 0, and 1), and four second-order polynomial regression equations were then derived to estimate the responses (COD and color removals) of two distinct systems. The significance of the independent model components and their interrelations were appraised by means of a variance analysis with 99% confidence limits (α = 0.01). The standardized differences of the independent variables and the consistency between the actual and predicted values were also investigated by preparing normal probability residual plots and experiment-model plots for all processes. The optimal operating conditions were attained by solving the quadratic regression models and analyzing the surface and contour plots. UV/Fenton and MW/Fenton processes, which constitute combined Fenton processes, were performed using advanced oxidation methods, while Fenton processes were utilized as the standard method for wastewater treatment. When UV/Fenton and MW/Fenton processes were applied separately, the COD removal efficiencies were determined to be 96.4% and 95.3%, respectively. For the color parameter, the removal efficiencies after the application of both processes were found to exceed 97.5%. While these efficiencies were achieved in 1 h with a 38 W UV unit, they were achieved in 15 min with a MW power of 570 W. According to the RSM-based regression analysis results, the R2 values for both processes were greater than 0.97 and p values were less than 0.003.

Published: February 2024

River water-level prediction is crucial for mitigating flood damage caused by torrential rainfall. In this paper, we attempt to predict river water levels using a deep learning model based on radar rainfall data instead of data from upstream hydrological stations. A prediction model incorporating a two-dimensional convolutional neural network (2D-CNN) and long short-term memory (LSTM) is constructed to exploit geographical and temporal features of radar rainfall data, and a transfer learning method using a newly defined flow–distance matrix is presented. The results of our evaluation of the Oyodo River basin in Japan show that the presented transfer learning model using radar rainfall instead of upstream measurements has a good prediction accuracy in the case of torrential rain, with a Nash–Sutcliffe efficiency (NSE) value of 0.86 and a Kling–Gupta efficiency (KGE) of 0.83 for 6-h-ahead forecast for the top-four peak water-level height cases, which is comparable to the conventional model using upstream measurements (NSE = 0.84 and KGE = 0.83). It is also confirmed that the transfer learning model maintains its performance even when the amount of training data for the prediction site is reduced; values of NSE = 0.82 and KGE = 0.82 were achieved when reducing the training torrential-rain-period data from 12 to 3 periods (with 105 periods of data from other rivers for transfer learning). The results demonstrate that radar rainfall data and a few torrential rain measurements at the prediction location potentially enable us to predict river water levels even if hydrological stations have not been installed at the prediction location.

Published: February 2024

This study developed a coupled atmospheric–marine model using the COAWST model system for the Harima Nada area between spring 2010 and winter 2011 to evaluate the seasonal influence of the Kako River’s discharge in the sea. The Kako River is one of the largest rivers in southwest Japan, contributing almost half of the freshwater discharged in the Harima Nada region in the Seto Inland Sea. Validation was conducted for the entire period, showing a good performance for the atmospheric and marine variables selected. Multiple experiments injecting an inert tracer in the Kako River estuary were performed to simulate the seasonal river water distribution from the estuary into the sea and to analyze the seasonal differences in concentration patterns and mean residence times in Harima Nada. Because the study area is shallow, the results were evaluated at the surface and 10 m depth layers and showed significant seasonal differences in tracer distribution, circulation patterns, and mean residence times for the region. On the other hand, differences seemed to not be significant during the same season at different depths. The obtained results also agreed with the area’s natural water circulation, showing that the Kako River waters tend to distribute towards the west coast of Harima Nada in the warmer seasons but shift towards the east in winter. The influence of the Kako River in the center of the study area is seasonal and strongly dependent on the direction of the horizontal velocities more than their magnitude. The mean residence times varied seasonally from approximately 30 days in spring to 12 days in fall. The magnitude of the horizontal velocity was found to be maximum during summer when circulation patterns at the surface and 10 m depth in the central part of Harima Nada also seem to promote the strongest horizontal and vertical mixes.

Published: February 2024

Accurately assessing the risk of flash floods is a fundamental prerequisite for defending against flash flood disasters. The existing methods for assessing flash flood risk are constrained by unclear key factors and challenges in elucidating disaster mechanisms, resulting in less-than-ideal early warning effectiveness. This article is based on official statistics of flash flood disaster data from 2017 to 2021. It selects eight categories of driving factors influencing flash floods, such as rainfall, underlying surface conditions, and human activities. Subsequently, a geographical detector is utilized to analyze the explanatory power of each driving factor in flash flood disasters, quantifying the contribution of each factor to the initiation of flash flood; the flash flood potential index (FFPI) was introduced to assess the risk of flash flood disasters in China, leading to the construction of a comprehensive assessment framework for flash flood risk. The results indicate that (1) Flash floods are generally triggered by multiple factors, with rainfall being the most influential factor, directly causing flash floods. Soil type is the second most influential factor, and the combined effects of multiple factors intensify the risk of flash floods. (2) The southeastern, southern, and southwestern regions of China are considered high-risk areas for flash floods, with a high danger level, whereas the northwestern, northern, and northeastern plain regions exhibit a lower danger level. The above research results provide reference and guidance for the prevention and control of flash flood disasters.

The energy inside the Earth can not only be released outward through earthquakes and volcanoes but also can be used by humans in the form of geothermal energy. Is there a correlation between different forms of energy release? In this contribution, we perform detailed seismic and geothermal research in the Beijing area. The results show that the geothermal resources in Beijing belong to typical medium-low temperature geothermal resources of the sedimentary basin, and some areas are controlled by deep fault activities (e.g., Xiji geothermal well (No. 17)). The heat sources are upper mantle heat, radioactive heat in granite, and residual heat from magma cooling. The high overlap of earthquakes and geothermal field locations and the positive correlation between the injection water and earthquakes indicate that the exploitation and injection water will promote the release of the earth’s energy. The energy releases are partitioned into multiple microearthquakes, avoiding damaging earthquakes (ML ≥ 5) due to excessive energy accumulation. Therefore, the exploitation of geothermal resources may be one way to reduce destructive earthquakes. Furthermore, the use of geothermal resources can also reduce the burning of fossil energy, which is of great significance in dealing with global warming.

Published: February 2024

It is essential to monitor the dynamics of vegetation at different scales in space and time to promote the sustainable development of terrestrial ecosystems. We used the Google Earth Engine (GEE) cloud platform to perform a comprehensive analysis of the changes in normalized difference vegetation index (NDVI) Mann-Kendall (MK) + Sen trend in the hinterland region of the Maowusu sandland in China over the last two decades. We performed bias-correlation studies using soil and climate data. Furthermore, we performed a partial Mantel test to analyze the spatial and temporal fluctuations of vegetation health-related indices. Additionally, we developed a logistic dual model of the phenology index using the Lenvenberg–Marquardt technique. The objective was to uncover the factors contributing to the regional shifts in vegetation dynamics. We provide a comprehensive analytic method designed to monitor vegetation over some time and forecast its future recovery. The findings indicate that over the past 20 years, more than 90% of the regional NDVI in the study area has exhibited a consistent and significant upward trend. This trend is primarily influenced by the adverse impact of temperature and the beneficial impact of precipitation. Additionally, long-term phenological indicators in the study area reveal that the vegetation’s growth cycle commences on the 125th day of the year and concludes on the 267th day of the year. This suggests that the shorter duration of the vegetation’s growth season may be attributed to the local climate and unfavorable groundwater depth conditions. levated temperatures throughout the next spring and autumn seasons would significantly affect the wellbeing of plants, with soil moisture being a crucial determinant of plant development in the examined region. This study presents a wide range of analytical tools for monitoring vegetation over a long period and predicting its future recovery. It considers factors such as vegetation health, phenology, and climatic influences. The study establishes a solid scientific foundation for understanding the reasons behind regional vegetation changes in the future.

Published: February 2024

Traditional hydrodynamic models face the significant challenge of balancing the demands of long prediction spans and precise boundary conditions, large computational areas, and low computational costs when attempting to rapidly and accurately predict the nonlinear spatial and temporal characteristics of fluids at the basin scale. To tackle this obstacle, this study constructed a novel deep learning framework with a hydrodynamic model for the rapid spatiotemporal prediction of hydrodynamics at the basin scale, named U-Net-ConvLSTM. A validated high-fidelity hydrodynamic mechanistic model was utilized to build a 20-year hydrodynamic indicator dataset of the middle and lower reaches of the Han River for the training and validation of U-Net-ConvLSTM. The findings indicate that the R2 value of the model surpassed 0.99 when comparing the single-step prediction results with the target values. Additionally, the required computing time fell by 62.08% compared with the hydrodynamic model. The ablation tests demonstrate that the U-Net-ConvLSTM framework outperforms other frameworks in terms of accuracy for basin-scale hydrodynamic prediction. In the multi-step-ahead prediction scenarios, the prediction interval increased from 1 day to 5 days, while consistently maintaining an R2 value above 0.7, which demonstrates the effectiveness of the model in the missing boundary conditions scenario. In summary, the U-Net-ConvLSTM framework is capable of making precise spatiotemporal predictions in hydrodynamics, which may be considered a high-performance computational solution for predicting hydrodynamics at the basin scale.

Published: February 2024

Soil-water characteristic curve (SWCC) is an essential parameter in unsaturated soil mechanics, and it plays a significant role in geotechnical engineering to enhance theoretical analysis and numerical calculations. This study investigated the effects of key factors, such as the percentage of sand, initial degree of saturation, and initial dry unit weight, on the SWCC of expansive soil by measuring the matric suction using a pressure apparatus method. The empirical equation of SWCC was obtained using the Van Genuchten and Fredlung Xing models, and the processing of experimental data checks the fitting of the two empirical models. The findings revealed that the Fredlung Xing model fit the relationship between matric suction and volumetric water content of expansive soil better than the Van Genuchten model, indicating that the pressure apparatus approach’s experimental data are correct and acceptable. The study also found that the matric suction increased with decreasing percentage of added sand at the same volumetric moisture content, and the increase in initial dry unit weight increased the matric suction, with the water retention capacity decreasing significantly after adding 20% sand. Moreover, as the initial degree of saturation increased, the volumetric water content decreased, and the characteristic curves became identical when the initial saturation degree reached 90%. Finally, to minimize the water retention capacity of expansive soils, the study recommended adding a percentage of sand not less than 30% to the expansive clay sample.

An experiment was conducted during the year 2020 to investigate the comparative effect of hydro and halopriming on seed germination and seedling growth of Ipil Ipil. The seeds of Ipil Ipil were primed in various solutions for 30 hours. The seeds were soaked in priming solutions viz. distilled water, luke warm water, NaCl solution @ 1% and 2%. The unprimed seeds were taken as control. The data was recorded for seed germination percentage, mean germination time (MGT), germination index (GI), seedling vigor index (SVI), fresh biomass of shoot, fresh biomass of roots, dry biomass of shoot, dry biomass of roots, quality index of the seedlings, sturdiness quotient and leakage of the electrolytes. The results revealed that all the observed parameters studied in the present study were significantly (P<0.05) influenced by various seed priming treatments. The results of seed priming depict that seed germination (90.00%), germination index (0.43), germination time (5.22 days) and seedling vigor index (1498.0) were observed better in response to the luke warm water. While the seeds primed with NaCl @ 1% had better results for fresh biomass of shoot (5.58 g), root (1.44 g), dry biomass of shoot (1.57 g) and root (0.29 g). Quality index of the seedlings and sturdiness quotient had better result from NaCl treatment. The quality of the seedlings was measured in terms of sturdiness quotient, quality index of the seedlings and leakage of the electrolytes. The sturdiness quotient (0.98), quality index of the seedling (24.85) was also better in response to the halo (NaCl) seed priming @ 1%. The only leakage of the electrolytes had no significant of seed priming. It is concluded from the present study that all seed germination related parameters are greatly affected by the lukewarm water treatment. However, parameters related with the seedling growth are affected by the NaCl treatment @ 1%.

L’insémination artificielle des reines d’abeilles mellifères (Apis mellifera) est pratiquée de manière efficace par les sélectionneurs depuis les années 60 grâce à un matériel de précision comprenant une chambre d’anesthésie, des crochets et une seringue micrométrique. Aujourd’hui, grâce à un matériel peu encombrant, éprouvé et perfectionné avec le temps, l’insémination d’Apis mellifera est fiable, rapide, facile d’accès et ne nécessite pas un entrainement trop long. L’opération se déroule dans des conditions d’asepsie stricte, sous une loupe binoculaire au grossissement 16. La technique consiste à maintenir ouverte la chambre de l’aiguillon de la reine préalablement anesthésiée au CO2 et maintenue dans une chambre d’anesthésie. Ensuite on récline la valvule génitale et on injecte en partie distale environ huit millions de spermatozoïdes dans la chambre antérieure, sous la valvule. La semence entrera ensuite passivement dans la spermathèque. Une reine peut être fécondée une seule fois pour ses cinq années de vie. Mots-Clés : Insémination artificielle, abeilles, Apis mellifera

De nombreuses études sur modèles animaux montrent que le microbiote intestinal affecte les réponses émotionnelles au stress. Dans ce contexte, nous avons étudié les effets d’un métabolite produit par le microbiote intestinal à partir du tryptophane, l’indole. Chez des modèles animaux dont nous avons manipulé le microbiote pour qu’il produise ou non de l’indole, nous avons montré que cette molécule intensifie les comportements de type anxieux et dépressif. Son action s’exercerait par une activation du nerf vague et l’imprégnation du cerveau par des dérivés secondaires de l’indole, produits par le foie. Dans une cohorte humaine destinée à étudier les relations nutrition-santé, nous avons montré une association positive entre symptômes dépressifs et production d’indole par le microbiote. Ces travaux illustrent l’importance de prendre en compte les activités métaboliques du microbiote intestinal dans la physiopathologie des troubles anxieux et de l’humeur. Mots-Clés : microbiote ; indole ; 3-indoxylsulfate ; stress ; nerf vague
La gestion des populations de rats et la résistance aux anticoagulants raticides
Authors: Lattard Virginie
Published: February 2024

La gestion des rongeurs repose sur une boîte à outils incluant des mesures préventives sanitaires, architecturales, agricoles et écologiques complétées par des mesures curatives qui peuvent être physiques ou chimiques. Les solutions chimiques applicables à large échelle sont peu nombreuses en raison du besoin de disposer de molécules à effet différé permettant de contourner l’aversion alimentaire des rongeurs, et en particulier du rat brun. Parmi ces solutions, les anticoagulants antivitamine K sont les plus largement utilisés dans le monde entier. En Europe, leur utilisation est encadrée par une règlementation stricte en raison des nombreux enjeux associés à leur utilisation. Après un aperçu des connaissances essentielles à la compréhension de l’action des anticoagulants rodenticides, cet article présente l’ensemble des enjeux liés à leur utilisation et les actions prises pour répondre à ces enjeux, en insistant sur les phénomènes de résistance impactant l’efficacité des gestions de rongeurs. Mots-clés : rongeurs, gestion, anticoagulants rodenticides, résistance, Vitamine K époxyde réductase, mutations

Les enfants malformés et handicapés à Rome sous le Principat
Authors: Allély Annie
Published: February 2024

L'étude consacrée aux enfants anormaux à Rome sous le Principat fait ressortir l'existence de deux sphères distinctes. La première sphère est publique et religieuse, et elle concerne, comme à l'époque républicaine, les prodigia qui sont toujours pris en compte par les haruspices. La seconde sphère est juridique et privée et c'est le paterfamilias, dans le cadre de sa patria potestas, qui décide ou pas de garder puis d'élever un enfant handicapé. Enfin, la condition de ces enfants, quelle que soit leur origine sociale, reste douloureuse à vivre au quotidien.
Dion Chrysostome et Euripide : de l’usage pédagogique d’un auteur tragique
Authors: Gangloff Anne
Published: February 2024

Dionus Chrysostomes's resort to Euripides's tragedies brings to light a certain amount of specificities which become more understandable once one studies how his dramatic work is perceived. It is considered rather ambivalent : both popular and close to philosophy. The political aspect of Euripides's eloquence and more particularly the aptness of his mode of expressing himself are both highlighted. These qualities demonstrate that the tragedies were made use of by Dionus to build up an educational type of eloquence with political, moral and philosophical aims, likely to make an impression on a large audience.
Denys lecteur des Phénomènes d’Aratos
Authors: Khan Yumna
Published: February 2024

Cette étude explore la relation existant entre la Périégèse de Denys et les Phénomènes d'Aratos. Ces deux poèmes présentent des similitudes évidentes en terme de longueur, de thème, de langue et de style ainsi qu'une allusion faite par Denys au texte d'Aratos. L'acrostiche de la Periégèse v. 307-311 dont la ressemblance par la forme avec celle de Phénomènes v. 783-787 a déjà été démontrée par Patrick Counillon, semble relier explicitement les poèmes. De toute évidence, il y a également des différences fondamentales entre ces deux poèmes telles que celles qui apparaissent dans leur structure bien distincte. Celles-ci sont également étudiées à la lumière des similarités discutées.
L. Aufidius L. F. Aem. Vinicianus Epagatinus (CIL., XII, 4357, Narbo) et Narbonne
Authors: Mathieu Nicolas
Published: February 2024

A Narbonne est connue l’inscription funéraire d’un chevalier originaire de Fundi , L. Aufidius Vinicianus Epagatinus, inscrit dans la tribu Aemilia, et de son épouse Olia Nice, une affranchie.

Grâce à une enquête onomastique, on envisage des connexions familiales possibles et on essaie de situer les origines sociales du couple, ses relations socio-économiques en Italie et en Narbonnaise au début de l’Empire au Ier s. ap. J.-C. Sont ainsi illustrées la mobilité et l’ascension sociale sur ces deux rives de la Méditerranée.
Isocrate, Xénophon ou le politique transfiguré
Authors: Azoulay Vincent
Published: February 2024

In traditional historiography politics are often defined in a narrow institutional manner. The analysis of the works of Isocrates and Xenophon tend however to demonstrate that such an approach is not the only relevant one. In the definition they give of the ideal politeia, their mores (tropoi or epitêdeumata) play a much more important role than do strictly judicial rules. These mores must also be guaranteed by the presence of a chief whose power relies not on a legal basis but on charismatic pratices -evergetism being first and foremost. By refusing the usual institutional frameworks, such a theoretical redefinition of politics foreshadows, in a certain way, the mutations of the hellenistic period.
L'Ionie à l'époque mycénienne. Essai de bilan historique
Authors: Zurbach Julien
Published: February 2024

Cette étude tente de s’appuyer sur l’ensemble des sources disponibles (toutes catégories de matériel archéologique, textes hittites, mycéniens ou égyptiens) pour esquisser une synthèse de l’histoire de l’Ionie au Bronze récent. On ne peut guère parler d’unité régionale mais la diversité qui caractérise cette région est le reflet de sa situation au contact de deux systèmes. L’intérêt considérable des textes hittites pour l’histoire égéenne est évident.
Sur une concordance textuelle entre Épicure et la collection Hippocratique
Authors: Giovacchini Julie
Published: February 2024

Certains textes du philosophe Épicure soulèvent de grandes difficultés d’interprétation, du fait de leur concision et de leur technicité. C’est le cas d’une phrase importante du § 75 de la Lettre à Hérodote , portant sur l’action réciproque de la «nature », des « réalités » et du « raisonnement ». Or, on retrouve cette sentence, sous une forme quasi identique, dans le traité déontologique de la Collection Hippocratique intitulé Préceptes. Comment expliquer cette concordance ? Quel arrière-plan philosophique, quel fond intellectuel commun peut-elle nous amener à esquisser, entre deux corpus en apparence si éloignés l’un de l’autre ?
Les émissions de monnaies d'homonoia et les crises alimentaires en Asie sous Marc-Aurèle
Authors: Kirbihler François
Published: February 2024

Different literary, epigraphic, numismatic, and papyrologie sources attest the presence of food crises at Ephesos and in Asia Minor (Mysia, Ionia, Lydia, Phrygia) between 165 and 170/1. The context was also tragic for the Roman Empire, because of barbarian attacks, the event of a great plague (smallpox ?), and bad harvests in Egypt.
Book Review: Social Justice Fallacies
Authors: Amos Charles
Published: February 2024

At the heart of _Social Justice Fallacies_ is a refutation of the verdicts of Progressives on the moral status of inequalities between the races, sexes and classes, on their own grounds. Following from this is a criticism of the state interventions proposed to correct these inequalities. Sowell considers three themes throughout the book to make his case, these being, the unchosen background of people, the different tastes of people, and, the responses which people make to Progressive policies to “fix” inequalities. By showing how a majority of the inequality between groups is due to these three factors, he defeats the central idea of the social justice movement, namely, ‘disparities are evidence or proof of the effects of such human vices as exploitation and discrimination’ (2). This is a good book grounded in plenty of empirical evidence and solid arguments. This review summarizes its three themes, outlines its secondary concerns, and offers minor criticism towards the end.

Suatu peristiwa kecelakaan lalu lintas sangat beragam baik dari proses kejadiannya maupun faktor penyebabnya. Untuk kepentingan penanggulangannya di perlukan adanya suatu pola yang dapat menggambarkan karakteristik proses kejadian suatu kecelakaan lalu lintas, agar dapat di simpulkan faktor penyebabnya supaya dapat dirumuskan pula upaya penanggulangannya. Dari hasil penelitian didapati indikator penyebab kecelakaan lalulintas yang terjadi menunjukkan bahwa faktor manusia 56,67%, faktor kendaraan 31,25%, faktor jalan dan lingkungan 15,63%. Kondisi permukaan jalan terdapat lebih dari satu kerusakan yaitu retak kulit buaya, retak pinggir, distorsi atau perubahan bentuk, jalan lubang-lubang, stripping atau pengelupasan lapisan permukaan, dan jalan bergelombang. Jalan yang digenangi air, adanya pasir di permukaan jalan, dan jalan yang mengalami penyempitan. Kondisi fasilitas jalan (rambu dan marka jalan) tidak adanya rambu yang seharusnya ada yaitu rambu pemberitahuan bahwa adanya persimpangan kanan, tidak adanya rambu pemberitahuan bahwa di depan ada penurunan, tidak terdapat lampu penerangan jalan, tidak terdapat marka tepi (kiri dan kanan) dan tidak di lengkapi mata kucing. Perbaikan serta pembersihan permukaan jalan yang mengalami kerusakan pada beberapa titik dan perlunya perbaikan dan penambahan fasilitas jalan (rambu dan marka jalan).
