Published: December 2021

Investment is an important element in modernizing agriculture. However, the studied industry is characterized by features that lead to risky activities. The purpose of the article is to study the problem of investing in the agricultural sector of Ukraine's economy and determine the degree of risks of this process in the context of modernization.

Studies show that investment is a necessary part of modernizing the agricultural sector of the economy. The specifics of investment in the agricultural sector of the economy, primarily due to the characteristics of the industry, ie depends on a variety of climatic, social, economic, financial and other factors. A key component of the investment process is to identify effective sources of funding. The analysis shows that 90% of the total investment in agriculture in Ukraine is the own funds of enterprises and organizations. In second place - loans in the form of loans and other loans (8.6%). Investment resources of the state and local budgets are extremely low – 0, 3 and 0.1%, respectively. All risk factors of the industry can be divided into internal and external.

Agriculture is an important sector of the economy, on the development of which depends the food security of the population. Economic analysis of the industry has shown the need for its modernization. One of the directions of modernization of agricultural production is the intensification of investment activity, which is at a low level of development due to the riskiness of the industry.
The analysis of the digital transformation trends in the Ukrainian economy
Authors: Snopenko Hanna , Balueva Olga , Tanchyk Olena
Published: December 2021

The consistent evolution of technology around the world creates new production tools and opportunities for different economic agents. As a result, new economic structures are emerging as a result of industrial revolutions. Today, the digital economy is seen as the backbone of the fourth industrial revolution, as there is a clear shift in the underlying technology and signs of a technological and economic paradigm shift. The current stage of the industrial revolution is associated with the Internet communication technologies development, which has significantly changed the technology of business processes and has been called "digitalisation". Thus, the fourth industrial revolution and the third wave of globalisation are based on the digital economy. The article explores trends in the development of the Ukrainian economy under the influence of ubiquitous digitalisation. Digital transformation changes traditional business models of organisations, allowing them to occupy profitable niches in global markets, raising the prestige of business and the state as a whole. In today's environment, the level of digitalisation illustrates the degree of companies' competitiveness and is a determining factor in development strategy. To analyse the processes of digitalisation and determine the place of Ukraine in the digital world, the article identifies and describes four zones of digital transformation, which are particular to the world economies. It is determined that Ukraine has fallen into a zone of prospective economies, where digital infrastructure is limited. Still, digital development is accelerating, indicating the potential for digitalisation to flourish, which will benefit economic recovery from the COVID-19 pandemic and long-term transformation. Ukraine's integral digital transformation index score is placed at 2.81 out of a possible 5 in 2021. It was determined that the main barriers to the digital transformation development in Ukrainian business include ineffective legislation, insufficient funding and low digital literacy of the population. However, the highest score among the index components was given to companies' overall level of digital transformation. A positive result of the survey is confirmation of increased investment in the digital technologies development in Ukraine: priority investments in this area include customer interaction, data analytics and HR management.
The consequences of ageing for the Polish economy

Published: December 2021

The ageing of population, as well as the expected decline resulting from the demographic changes, may have a negative effect on the economy, burdening national budgets. Poland has been among 30 demographically old countries in the world for years, and the ageing of the population has already begun in the early 1970s (Majdzińska A., 2015). The subject of the study is the economic effects of ageing society in Poland. The aim of the article is to present the economic consequences of ageing in Poland. The data from the Central Statistical Office on the demographic situation in Poland are used in the article. The ageing of the population is perceived as the dominant demographic process reflecting changes in the age structure of the population and the growth in the general elderly population. Therefore, the task of the state policy is to ensure the most optimal development for ageing population. The ageing of society imposes many tasks for social policy, including pension deficits, increase in healthcare service costs and care for the elderly, as well as slowing down in economic growth in the context of increasing social costs (P. Błędowski, 2012). Human ageing is a natural process, and at the same time, it has become a subject of interest among researchers working in various scientific environments. Therefore, it is necessary to regularly observe changes and undertake extensive discussions in this regard. It goes without saying that the course of aging process and its consequences require increased attention from experts and politicians. It is necessary to take up-to-date actions that will mitigate the negative effects in the future.

Published: December 2021

In this article we study the thermodynamic limit of the form factors of the XXX Heisenberg spin chain using the algebraic Bethe ansatz approach. Our main goal is to express the form factors for the low-lying excited states as determinants of matrices that remain finite dimensional in the thermodynamic limit. We show how to treat all types of the complex roots of the Bethe equations within this framework. In particular we demonstrate that the Gaudin determinant for the higher level Bethe equations arises naturally from the algebraic Bethe ansatz.
ZINC CONTAMINATION IS AN UNDERESTIMATED RISK TO AMPHIBIANS: TOXICITY EVALUATION IN TADPOLES OF FEJERVARYA LIMNOCHARIS
Authors: Patar Arabinda , Das Indranil , Giri Sarbani , Giri Anirudha
Published: December 2021

Aquatic environments are often contaminated with zinc. Amphibian tadpoles are likely to be exposed to high concentrations of zinc present in these environments. We determined the acute and sub-chronic toxicity of ZnCl2 on Fejervarya limnocharis tadpoles under laboratory conditions. The LC50 values of ZnCl2 were found to be 5.81, 4.32, 3.79 and 3.61 mg/L at 24, 48, 72 and 96 h of exposure respectively. Long-term exposure to sub-lethal concentrations of ZnCl2 induced significant mortality in concentration and time dependent manner. Sub-lethal ZnCl2 exposure significantly altered survival, body length and body weight at metamorphosis. Micronucleus test and comet assay indicated the genotoxic potential of ZnCl2. Significant increase in DNA strand break was observed following ZnCl2 exposure equivalent to 1% of the of 24 h LC50 value. The findings indicate possible adverse to tadpoles inhabiting aquatic environments contaminated with zinc. In addition, the findings may be extrapolated to aquatic organisms of similar torphic status.

Published: December 2021

Urban taxi services have been developing year on year, playing an increasingly important role in the economy and the transportation markets of each city. This increases interest in measuring their performance. This paper analysed the relationship among the four stakeholders (including administrative department, operational companies, taxi drivers and customers) for urban taxi passenger transport system in China, and applied System Dynamics (SD) model to explore the dynamic characteristics of urban taxi price system. The main achievements of this paper are as follows, firstly, this paper adopted stakeholder mapping to describe the relationships among the four stakeholders. Then analysed the causal flow diagrams and the different variables of urban taxi passenger transport system operation, and presented the SD model, which considers factors that affect the taxi operation. With the combination of taxi operation data of Harbin city, we simulated eleven urban taxi operation scenarios and proposed kinds of suggestions to improve urban taxi passenger transport system operation, which can provide a good basis for recommending policy decisions for urban taxi market.
On the Properties of Spectroscopically Confirmed Ultra-diffuse Galaxies across Environments

Published: December 2021

We present new redshift measurements for 19 candidate ultra-diffuse galaxies (UDGs) from the Systematically Measuring Ultra-Diffuse Galaxies (SMUDGes) survey after conducting a long-slit spectroscopic follow-up campaign on 23 candidates with the Large Binocular Telescope. We combine these results with redshift measurements from other sources for 29 SMUDGes and 20 non-SMUDGes candidate UDGs. Together, this sample yields 44 spectroscopically confirmed UDGs (r

e
≥ 1.5 kpc and μ

g
(0) ≥ 24 mag arcsec−2 within uncertainties) and spans cluster and field environments, with all but one projected on the Coma cluster and environs. We find no statistically significant differences in the structural parameters of cluster and noncluster confirmed UDGs, although there are hints of differences among the axis ratio distributions. Similarly, we find no significant structural differences among those in locally dense or sparse environments. However, we observe a significant difference in color with respect to projected clustercentric radius, confirming trends observed previously in statistical UDG samples. This trend strengthens further when considering whether UDGs reside in either cluster or locally dense environments, suggesting starkly different star formation histories for UDGs residing in high- and low-density environments. Of the 16 large (r

e
≥ 3.5 kpc) UDGs in our sample, only one is a field galaxy that falls near the early-type galaxy red sequence. No other field UDGs found in low-density environments fall near the red sequence. This finding, in combination with our detection of Galaxy Evolution Explorer NUV flux in nearly half of the UDGs in sparse environments, suggests that field UDGs are a population of slowly evolving galaxies.

We present estimates for the number of shadow-resolved supermassive black hole (SMBH) systems that can be detected using radio interferometers, as a function of angular resolution, flux density sensitivity, and observing frequency. Accounting for the distribution of SMBHs across mass, redshift, and accretion rate, we use a new semianalytic spectral energy distribution model to derive the number of SMBHs with detectable and optically thin horizon-scale emission. We demonstrate that (sub)millimeter interferometric observations with ∼0.1 μas resolution and ∼1 μJy sensitivity could access >106 SMBH shadows. We then further decompose the shadow source counts into the number of black holes for which we could expect to observe the first- and second-order lensed photon rings. Accessing the bulk population of first-order photon rings requires ≲2 μas resolution and ≲0.5 mJy sensitivity, whereas doing the same for second-order photon rings requires ≲0.1 μas resolution and ≲5 μJy sensitivity. Our model predicts that with modest improvements to sensitivity, as many as ∼5 additional horizon-resolved sources should become accessible to the current Event Horizon Telescope (EHT), whereas a next-generation EHT observing at 345 GHz should have access to ∼3 times as many sources. More generally, our results can help guide enhancements of current arrays and specifications for future interferometric experiments that aim to spatially resolve a large population of SMBH shadows or higher-order photon rings.
On the Mass Loading of AGN-driven Outflows in Elliptical Galaxies and Clusters

Published: December 2021

Outflows driven by active galactic nuclei (AGNs) are an important channel for accreting supermassive black holes (SMBHs) to interact with their host galaxies and clusters. Properties of the outflows are however poorly constrained due to the lack of kinetically resolved data of the hot plasma that permeates the circumgalactic and intracluster space. In this work, we use a single parameter, outflow-to-accretion mass-loading factor

m

, to characterize the outflows that mediate the interaction between SMBHs and their hosts. By modeling both M87 and Perseus, and comparing the simulated thermal profiles with the X-ray observations of these two systems, we demonstrate that m can be constrained between 200 and 500. This parameter corresponds to a bulk flow speed between 4000 and 7000 km s−1 at around 1 kpc, and a thermalized outflow temperature between 108.7 and 109 K. Our results indicate that the dominant outflow speeds in giant elliptical galaxies and clusters are much lower than in the close vicinity of the SMBH, signaling an efficient coupling with and deceleration by the surrounding medium on length scales below 1 kpc. Consequently, AGNs may be efficient at launching outflows ∼10 times more massive than previously uncovered by measurements of cold, obscuring material. We also examine the mass and velocity distribution of the cold gas, which ultimately forms a rotationally supported disk in simulated clusters. The rarity of such disks in observations indicates that further investigations are needed to understand the evolution of the cold gas after it forms.

The ejecta velocities of Type Ia supernovae (SNe Ia), as measured by the Si ii
λ6355 line, have been shown to correlate with other supernova properties, including color and standardized luminosity. We investigate these results using the Foundation Supernova Survey, with a spectroscopic data release presented here, and photometry analyzed with the SALT2 light-curve fitter. We find that the Foundation data do not show significant evidence for an offset in color between SNe Ia with high and normal photospheric velocities, with Δc = 0.004 ± 0.015. Our SALT2 analysis does show evidence for redder high-velocity SNe Ia in other samples, including objects from the Carnegie Supernova Project, with a combined sample yielding Δc = 0.018 ± 0.008. When split on velocity, the Foundation SNe Ia also do not show a significant difference in Hubble diagram residual, ΔHR = 0.015 ± 0.049 mag. Intriguingly, we find that SN Ia ejecta velocity information may be gleaned from photometry, particularly in redder optical bands. For high-redshift SNe Ia, these rest-frame red wavelengths will be observed by the Nancy Grace Roman Space Telescope. Our results are in line with previous work that suggests SN Ia host-galaxy stellar mass is correlated with ejecta velocity: high-velocity SNe Ia are found nearly exclusively in high-stellar-mass hosts. However, host-galaxy properties alone do not explain velocity-dependent differences in supernova colors and luminosities across samples. Measuring and understanding the connection between intrinsic explosion properties and supernova environments, across cosmic time, will be important for precision cosmology with SNe Ia.
Shock-wave Radio Probing of Solar Wind Sources in Coronal Magnetic Fields

Published: December 2021

The space weather effects in the near-Earth environment as well as in atmospheres of other terrestrial planets arise by corpuscular radiation from the Sun, known as the solar wind. The solar magnetic fields govern the solar corona structure. Magnetic-field strength values in the solar wind sources—key information for modeling and forecasting the space weather climate—are derived from various solar space- and ground-based observations, but so far not accounting for specific types of radio bursts. These are “fractured” type II radio bursts attributed to collisions of shock waves with coronal structures emitting the solar wind. Here, we report on radio observations of two “fractured” type II bursts to demonstrate a novel tool for probing of magnetic-field variations in the solar wind sources. These results have a direct impact on interpretations of this class of bursts and contribute to the current studies of the solar wind emitters.
Amoeba: Automated Molecular Excitation Bayesian Line-fitting Algorithm
Authors: Hafner Anita , Dawson J. R. , Wardle Mark
Published: December 2021

The hyperfine transitions of the ground-rotational state of the hydroxyl radical (OH) have emerged as a versatile tracer of the diffuse molecular interstellar medium. We present a novel automated Gaussian decomposition algorithm designed specifically for the analysis of the paired on-source and off-source optical depth and emission spectra of these OH transitions. In contrast to existing automated Gaussian decomposition algorithms, Amoeba (Automated Molecular Excitation Bayesian line-fitting Algorithm) employs a Bayesian approach to model selection, fitting all four optical-depth and four emission spectra simultaneously. Amoeba assumes that a given spectral feature can be described by a single centroid velocity and full width at half maximum, with peak values in the individual optical-depth and emission spectra then described uniquely by the column density in each of the four levels of the ground-rotational state, thus naturally including the real physical constraints on these parameters. Additionally, the Bayesian approach includes informed priors on individual parameters that the user can modify to suit different data sets. Here we describe Amoeba and establish its validity and reliability in identifying and fitting synthetic spectra with known (but hidden) parameters, finding that the code performs very well in a series of practical tests. Amoeba’s core algorithm could be adapted to the analysis of other species with multiple transitions interconnecting shared levels (e.g., the 700 MHz lines of the first excited rotational state of CH). Users are encouraged to adapt and modify Amoeba to suit their own use cases.

Previous observations have shown that the ≲10 au, ≳400 K hot inner disk of the archetypal accretion outburst young stellar object, FU Ori, is dominated by viscous heating. To constrain dust properties in this region, we have performed radio observations toward this disk using the Karl G. Jansky Very Large Array in 2020 June–July, September, and November. We also performed complementary optical photometric monitoring observations. We found that the dust thermal emission from the hot inner disk mid-plane of FU Ori has been approximately stationary and the maximum dust grain size is ≳1.6 mm in this region. If the hot inner disk of FU Ori, which is inward of the 150–170 K water snowline, is turbulent (e.g., corresponding to a Sunyaev & Shakura viscous α

t
≳ 0.1), or if the actual maximum grain size is still larger than the lower limit we presently constrain, then as suggested by the recent analytical calculations and the laboratory measurements, water-ice-free dust grains may be stickier than water-ice-coated dust grains in protoplanetary disks. Additionally, we find that the free–free emission and the Johnson B- and V-band magnitudes of these binary stars were brightening in 2016–2020. The optical and radio variability might be related to the dynamically evolving protostellar- or disk-accretion activities. Our results highlight that the hot inner disks of outbursting objects are important laboratories for testing models of dust grain growth. Given the active nature of such systems, to robustly diagnose the maximum dust grain sizes, it is important to carry out coordinated multiwavelength radio observations.
Cardiovascular Diseases Healthy Diet Related Knowledge among a Sample of the General Population in Egypt
Authors: Zein Marwa M. , Mahmoud Ahmed Taher , El Hawary Ahmed Sallam , Hegazy Nelly
Published: December 2021

BACKGROUND: Little is known about the extent of Egyptians’ awareness regarding the relationship between nutrition and cardiovascular health.

AIM: This study seeks to evaluate people’s awareness through an online cross-sectional survey to determine the knowledge gaps.

METHODS: This cross-sectional study was conducted through an online survey using a convenience sampling technique. The participation required being an adult Egyptian (≥18 years old). A pre-tested electronic-questionnaire included three sections: Socio-demographic data, a self-reported history of chronic and cardiac diseases, and 15 questions addressing dietary risk factors and protective factors. Six hundred and thirty-two participants completed the questionnaire.

RESULTS: The mean age was 28 ± 8 years. More than 80% of the participants were males. Of 632 participants, 233 had poor awareness. The median knowledge percent score was 62 with interquartile range (52, 71). About 85.4% of the participants were ready to change their eating habits and follow a healthy diet to maintain their health. The participants were interested in knowing more about healthy food and how to prepare healthy balanced meals (71.7% and 62.2%, respectively). Females, university-educated, employed, and Upper Egypt residents demonstrated deep awareness (p-value = 0.02, 0.011, 0.05, and 0.012, respectively). Intriguingly, friends and social media were the primary sources of nutritional knowledge.

CONCLUSION: The participants’ knowledge is poor regarding the relation between nutrition and cardiovascular health. This study emphasizes the urgent need to raise public awareness as a precaution against cardiovascular diseases.

Published: December 2021

The recent decades saw a steady growth of obesity incidence worldwide. Obesity is an independent risk factor for cardiovascular diseases (CVDs) and type 2 diabetes mellitus and is also associated with a shorter life expectancy. Not only hemodynamic but also hormone metabolic processes, arising from excessive accumulation of adipose tissue in human body, underlie the development of CVDs. Adipose tissue has now been proved to be a hormone-active substrate. Studies of the influence of adipokines will bring us closer to understanding cardiovascular pathogenesis and help personalize prophylactic strategies.
Cardiovascular Risk in Patients with COPD: Cardiovascular Comorbidities in Patients with COPD Increase CAT and mMRC Dyspnea Scores
Authors: Stojkovic Jagoda , Antova Emilija , Stojkovikj Dragana
Published: December 2021

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with a number of different comorbidities. Cardiovascular diseases (CVD) are the most frequent comorbidities in COPD. The economic burden associated with cardiovascular comorbidity (CVC) in this population of patients is considerable. The COPD patients are related to the increased systemic inflammation, reduced capacity for physical activity, and airflow obstruction.

AIM: The aim of our investigation was to evaluate the dyspnea as a disabling symptom in COPD patients with cardiovascular comorbidity (CVC) especially heart failure. The main aim of this study is to evaluate its intensity in patients with COPD in stages II according to GOLD.

METHODS: The investigation was conducted from December 2019 to January 2020, on pulmonology and allergology clinic and cardiology clinic of medical faculty in Skopje. We investigated 65 outpatients with COPD, 44 with different type of CVD, Group I, and 21 without CVD, Group II. All patients were with partial chronic respiratory failure (In type 1 respiratory failure hypoxemic). Patients, according GOLD initiative, were in COPD stadium II, 70% < forced expiratory volume in 1 s (FEV1)>50%. Heart condition was diagnosed on the basis of clinical examination, electrocardiography, and echocardiography of the heart. Included patients with CVD were with ejection fraction (EF) <65%. Dyspnea was measured with modified MRC (mMRC) dyspnea scale.

RESULTS: The forced vital capacity and forced expiratory volume in 1 s were statically significantly higher in Group II with CVD. Dyspnea measured with Modified Medical Research Council (MRC) dyspnea scale showed statistically significantly higher values in Group I COPD patients with CVC (2.9 ± 1.4) versus Group II without CVC (1.7 ± 1.4), (p < 0.05). The perception of the higher dyspnea in Group I was associated with increased COPD assessment test-scores, in Group I: Group I (19.8 ± 9.1) versus Group II: (9.8 ± 9.1), (p < 0.001). The number of exacerbations and what is more important the number of severe exacerbation leading to hospitalizations was statistically higher in patients of Group I with CVC than in Group II without CVC (3.0 ± 1.1 vs. 1.0 ± 2.1), (p < 0.001) and the number of hospitalizations (1.0 ± 1.1 vs. 0.3 ± 2.1) (p < 0.001).

CONCLUSION: We can conclude that patients with COPD who have CVC have an increased risk of high symptoms, which mean poor quality of life and increased morbidity.

Published: December 2021

Cet article vise à décrire la possibilité de travailler en institution de manière groupale avec une famille d’accueil et un enfant placé au long cours. En s’appuyant sur le suivi thérapeutique d’une enfant et de son assistante familiale, l’auteur privilégie l’aspect clinique. Les concepts présentés traitent de l’affiliation en tant que potentiel recours à la résolution d’un trauma sur les origines. Le cadre thérapeutique correspond au néo-groupe, sa contenance et l’émergence progressive de souvenirs, travaillés par des médiations. Les chaînes associatives groupales sont fonction du transfert et du contretransfert au sein d’une structure médico-sociale. L’article passe en revue différentes temporalités thérapeutiques jusqu’à l’étape d’un assouplissement de certains mécanismes de défense. Le réel des faits est cependant toujours resté hors champ.
Évolutions théoriques et méthodologiques des thérapies psychanalytiques en couple
Authors: Lemaire Jean-Georges
Published: December 2021

Les thérapies psychanalytiques auprès des couples apportent un bénéfice thérapeutique personnel à chacun des patients et, souvent, à leur lien douloureux ambivalent, comme en témoigne une méta-analyse comparative des approches thérapeutiques anciennes ou contemporaines. Une compréhension psychanalytique plus groupale s’impose aujourd’hui pour mieux saisir les problématiques identitaires mises en jeu par les processus inconscients qui structurent tout groupe humain, mais aussi la spécificité groupale transgénérationnelle des familles et des couples, laquelle donne à leur vie émotionnelle et affective une si grande intensité.
The Villa of Diomedes
Authors: Dessales Hélène
Published: December 2021

Ancrer la fabrique de la Villa de Diomède dans celle de la cité constituait le premier enjeu de notre recherche. Différentes hypothèses sur les dynamiques urbanistiques dans le secteur nord-ouest de Pompéi sont ici développées, en cherchant à identifier des opérations d’organisation du territoire et d’urbanisme. Quatre types de carroyages distincts, correspondant chacun à des structures de même orientation, permettent de rendre compte de la totalité des éléments bâtis à l’extérieur de la Porta Ercolano . Ce raisonnement sur l’orientation des bâtiments s’appuie sur la définition d’une série de grilles orthonormées, ce qui nous a conduits à préciser les unités de référence de chacune de ces organisations, en nous inspirant du carroyage observable dans la Regio VI, ce dernier fondé sur des îlots de 120 pieds osques 3 . Ainsi, un même système orthonormé concerne la Regio VI intra muros et les villas au nord-ouest des murailles, parmi lesquelles la Villa de Diomède. L’ensemble des éléments recueillis corroborent l’appartenance d’une série de propriétés à une organisation rationnelle du territoire remontant à la période samnite. Par ailleurs, il s’agissait d’envisager la relation spatiale et chronologique entre la Villa de Diomède et la Via delle Tombe et de reprendre une interrogation centrale abordée par Fausto Zevi 4 , développant la belle hypothèse selon laquelle l’ouverture de la Via delle Tombe , au moment de la déduction de la colonie, aurait entaillé l’entrée originelle de la Villa de Diomède, à l’origine de son plan actuel quelque peu tronqué. L’appel à des sources textuelles, en particulier celles que constitue le corpus des arpenteurs romains, permet d’aborder ce questionnement selon un angle de vue plus large, en distinguant clairement deux objets et deux niveaux de réflexion : le terrain et la construction. Enfin, l’existence d’un état originel de la villa, transformé lors de l’aménagement successif de la Via delle Tombe , semble confirmée par les données archéologiques : l’analyse stratigraphique, la typologie des techniques de construction, principalement murs et ouvertures, mais aussi l’interprétation des prospections géophysiques 5  permettent de restituer le premier plan du bâtiment. Précisons que dans sa planimétrie même et de par sa situation périurbaine, ce que nous appelons par convention « villa » pourrait fort bien avoir joué le rôle d’une domus , y compris dans ses usages sociaux et politiques. Si la datation de cette phase initiale reste très conjecturelle, la typologie des techniques de construction et l’identification des éléments liés au développement de la zone de la Porta Ercolano convergent vers un horizon chronologique de la seconde moitié du ii e  siècle av. n.è., cadre que nous proposons de retenir ici pour l’implantation de villa, sans qu’il ne soit possible de l’affiner en l’état actuel de nos connaissances.

De ce point de vue, la Villa de Diomède correspond aussi parfaitement à la définition d’un palimpseste architectural, issu de chantiers successifs, comme autant de calques venus se superposer. Il apparaît très nettement que les différentes transformations du bâtiment entreprises à la suite du projet originel en ont permis une bien plus grande extension vers l’ouest et vers le sud, à supposer, comme nous venons le voir plus avant, que son état initial ait été partiellement entaillé par l’aménagement de la Via delle Tombe . Au total, cinq grands aménagements successifs ont été déterminés. Le premier (chantier 1), caractérisé par des indices très ténus, semble correspondre à un seul chantier de construction, peut-être lié à une phase transitoire de restructuration du bâtiment suite à l’implantation de la Via delle Tombe . Le deuxième (chantier 2) se décompose en quatre chantiers successifs, dont le déroulement a pu se faire sur un temps assez long, dans le courant du i er  siècle av. J.-C. Le troisième (chantier 3), de toute aussi grande ampleur que le précédent, se décompose en quatre chantiers de construction, sur un temps peut-être un peu plus resserré, avec un achèvement à l’époque julio-claudienne. Le quatrième (chantier 4), organisé en deux chantiers distincts, fait suite au tremblement de terre de 62/63 apr. J.-C. Pour le cinquième (chantier 5), il n’a pas été possible d’individualiser différentes étapes de construction, dans la mesure où il s’agit d’interventions très ponctuelles à l’échelle du bâtiment, probablement successives à un ordre épisode sismique et de peu antérieures à 79. De fait, au moment de l’éruption du Vésuve, la villa semblait encore en cours de travaux. La priorité a donc été donnée à la détermination des chantiers de construction, mais aussi de décoration, afin de retracer avec précision la fabrique et la « refabrique » constante de cette grande villa à l’époque antique. Restons toutefois conscients que la temporalité de ces chantiers nous échappe en grande partie et que les éléments de datation proposés s’en tiennent principalement à l’état final des réalisations.

Question à la planétarité apeurée
Authors: Querrien Anne
Published: December 2021

La référence à la planétarité (et à ses prédictions computationnelles) n’est-elle pas un opérateur d’abstraction, qui nous angoisse en nous coupant des rapports de proximité, de familiarité et d’improvisation qui font le ressort de nos pratiques effectives sur nos terrains concrets d’existence ?
Lettre sur la planétarité vue depuis ma fenêtre
Authors: Dubacq Marianne
Published: December 2021

Comment penser le rapport entre nos discours de planétarité et les gestes qui définissent notre quotidien ? Nos gestes (prétendument) écologiques sont-ils autre chose que des spectacles rituels nous aidant à mettre à distance les réalités de nos existences ? Cette brève lettre à un ami anonyme pose plus de questions qu’elle n’en résout.

Empire, Race, Climat
Authors: Amer Meziane Mohamed

Une dizaine de thèses contre la liquidation sommaire des « religions » opérée par les descendants de Feuerbach aident à réinterpréter l’Anthropocène comme étant un Sécularocène. Et si le Ciel qui menace désormais de brûler notre planète était celui-là même que nous avons cru pouvoir enterrer trop insolemment ? Et si le rapport actuel de la République à l’islam illustrait dramatiquement cette insolence ?
La planète est-elle un complot ?
Authors: Rasmi Jacopo
Published: December 2021

C’est en regardant le portrait aberrant de la planétarité reflétée sur le miroir des complotismes environnementaux que la difficulté collective d’assumer cette échelle écologique se dévoile impitoyablement. Un tel malaise n’est pas seulement lié à une incapacité humaine et individuelle d’accepter la complexité de la crise planétaire. Elle émane de l’ensemble des rapports socio-politiques (verticaux, élitistes) que nous entretenons avec les méditations techniques qui permettent la perception, mais aussi la réparation, de notre planète.

À quoi ressembleront nos réveils en 2040, selon que nous aurons su – ou non – nous mobiliser politiquement à l’échelle planétaire pour limiter et mitiger la présence de CO 2 dans l’atmosphère de la seule Terre où nous puissions vivre ?
Empire et la gauche brésilienne
Authors: Cocco Giuseppe , De Roo Priscilla
Published: December 2021

Deux décennies après la publication d’ Empire par Antonio Negri et Michael Hardt le bilan est nuancé. Un point de vue brésilien et ami permet d’appréhender à la fois ce qui s’est confirmé au cours de ces années et ce qui au contraire nécessite un nouvel effort d’analyse. L’épuisement de l’expérience des gouvernements progressistes d’Amérique du Sud et la réflexion autobiographique demandent une révision des notions de gauche, de révolution, de luttes, de rapports entre processus constituants et logiques de pouvoir. L’article termine par une évaluation critique de la loyauté de Negri envers la gauche – active pour le « lulisme », passive pour le « chavisme ».

L’esthétique contre l’esthétisation : Lyotard et la tautégorie de l’œuvre d’art
Authors: Sevastyanov Aleksey
Published: December 2021

Le projet lyotardien de « réécrire la modernité » se construit à partir de la division kantienne entre le jugement déterminant et le jugement réfléchissant esthétique. La seule voie, pour l’œuvre d’art, de ne pas retomber dans une représentation, serait de devenir le témoin du « désastre » sublime, ou, autrement, d’une incompatibilité principielle entre le mode logique et le mode esthétique. Cependant cette projection du caractère tautégorique du jugement réfléchissant sur une œuvre d’art s’avère, d’une part, problématique car il s’agit d’un concept extra-artistique et, d’autre part, potentiellement contradictoire car elle semble reproduire – sur un niveau diffèrent, certes – la logique de la représentation (dans le sens où il s’agit de représenter le « désastre » sublime par le moyen de la peinture par exemple).
Le saint et le héros : une pierre d’achoppement pour la philosophie morale ?
Authors: Biancu Stefano
Published: December 2021

À partir de l’article « Saints and Heros » de James Urmson (1958), les catégories de saint, de héros et de surérogatoire sont entrées de plein droit dans le vocabulaire de la philosophie morale de langue anglaise, après l’exclusion qu’en avait faite la tradition. Récemment, dans le contexte de ce qu’on appelle «  Heroism science  », certains proposent cependant de séparer le saint et l’héroïque au sens moral, en soutenant le caractère extra-moral de l’héroïsme dans l’intention explicite d’en encourager la diffusion dans les sociétés contemporaines. À partir des réflexions sur le héros de Maurice Merleau-Ponty et d’Henri Bergson, on cherche à montrer dans cet article que l’héroïsme est en tout point un phénomène moral correspondant à la dynamique de la liberté humaine et constituant l’objet d’une obligation surérogatoire non exigible.
Les moines de Tibhirine ou le martyre au quotidien
Authors: Routhier Gilles
Published: December 2021

Alors que, dans les deux camps, les martyrs étaient nombreux dans l’Algérie soumise aux convulsions de la violence aveugle, Christian de Chergé réfléchit à la réalité du martyre. Non pas que cette réalité le fascine et l’attire, mais pour approfondir le choix qu’ont fait les moines de demeurer en Algérie, malgré ce climat de terreur qui les cernait. La notion de « martyre de l’amour » qui décrit le don de la vie au quotidien, dans le coude à coude et le goutte-à-goutte, finit par s’imposer. Le martyr, c’est celui qui donne sa vie à travers ce qui est le plus ordinaire, tout au long de ses jours. C’est celui qui consent à vivre sa Pâques, assumant la dimension eschatologique de sa propre existence.
L’héroïsme éthique selon Kierkegaard : être fidèle à soi
Authors: Collin Dominique
Published: December 2021

Qui est le héros chrétien ? Kierkegaard répond : celui dont l’immense tâche et non moins immense responsabilité est de devenir entièrement soi. Il en va d’une exigence éthique – être soi – qui ne s’adresse pas uniquement aux « singularités exceptionnelles » mais concerne chacun. Mais comment répondre à cette exigence ? En suivant les modèles de Job, de la prophétesse Anne et de Jean le Précurseur que Kierkegaard, dans les Dix-huit Discours édifiants de 1843-44, présente comme les figures de la fidélité à l’amour, nous les montrant comme de véritables « héros de l’espérance ». Le lecteur découvre ainsi une voie d’accomplissement éthique qui n’exige rien d’autre de lui que de renoncer à la part maudite de son moi afin de pouvoir faire la part de l’autre .
L’enseignement de Nietzsche à l’épreuve du Feu
Authors: Beltran-Vidal Danièle
Published: December 2021

Il est possible de trouver dans l’œuvre de Nietzsche des définitions de la « culture » qui permettent d’éclairer la notion de « culture de guerre » employée par certains historiens. Sur le front naissent nécessairement de nouvelles valeurs. Certains soldats retirèrent de leur expérience terrible et traumatisante une « vérité » difficilement transmissible par la suite à leurs compatriotes. Ils continuèrent de voir dans le sacrifice de leurs camarades une manifestation de « l’idéal ascétique ». Nietzsche condamne quant à lui avec force l’idéal ascétique : il tente d’en dévoiler la nocivité mettant en danger, à ses yeux, le « devenir ». En s’appuyant sur les écrits, en particulier, de Georges Bernanos, Ernst Jünger et Pierre Teilhard de Chardin, on voit que non seulement, ce ne fut pas le cas, mais que ce fut même le contraire.
