Tourism is considered by local inhabitants and businesses as an activity that could bring economic development to a very isolated and underdeveloped area such as the Danube Delta, UNESCO protected natural wetland. The aim of this study is to propose the Tourism Impact Model (TIM) as a tool that could be used by local and regional authorities in managing tourism in such fragile ecosystems so that to maximise its positive effects while the honeypot sites of the delta to attract tourists without provoking irreparable damage to the environment. The results of the TIM analysis applied for Sfântu Gheorghe commune evidence that the Danube Delta is under tourism pressure and at high risk of surpassing its human carrying capacity. The conclusions of the analysis show that TIM could be a very useful administrative and policy supporting tool in sustainable development governance if data collection improves in the future.
ANALYSIS OF LANDSCAPE TRANSFORMATIONS IN THE URBAN-RURAL GRADIENT OF THE METROPOLITAN DISTRICT OF QUITO
Authors: ORTIZ-BÁEZ Paola , CABRERA-BARONA Pablo , BOGAERT Jan
Published: July 2022

In contexts of globalization, economic restructuring and information and communication revolution, the relocation of services in peripheries and new urban expansion patterns have drastically altered periurban landscapes. However, due to its transformation speed, there is limited knowledge regarding the spatiotemporal changes of these interstitial territories. Calculating landscape metrics in high resolution satellite images, this research analyses spatiotemporal transformations in the Metropolitan District of Quito urban-rural gradient, testing a novel and accurate method to identify urbanization tendencies. The results evidence the main role that new road-infrastructures have had in the urban expansion. Also, the analyses identify significant changes in agricultural coverages (related to rural lots subdivision) and the processes of vegetation fragmentation, evidencing the environmental fragility of these territories in transformation. Finally, the Markov chains modelling technique was applied, exploring the landscape change probabilities in the following years. This methodology can be particularly useful in land-use planning policies since it provides precise knowledge about the main tendencies of urbanization.

Published: July 2022

This study aims to determine the level of household food security in coastal communities. The research was carried out in 2020 in Lantagi Village, Kulisusu District, North Buton Regency. Samples were taken by simple random sampling with a total sample of 35 people. The data analysis used is descriptive quantitative and analysis of food security status using the household food security module developed by the United States Development of Agriculture. The results showed that the level of household food security status of coastal communities was low. This is because most of the fishermen in the research location are classified as poor, and their source of income only relies on fishing activities. Where fishing activities in the sea are also very dependent on traditional fishing gear, sea conditions, waves, weather/seasons. The steps usually taken by fishermen when facing low-income situations so that household food availability remains adequate are buying cheaper food, reducing food consumption, and sometimes borrowing money from family or neighbors.
A heuristic approach to optimizing the loading of homogeneous marine cargo
Authors: Bernardelli Michał
Published: July 2022

In this article, the optimal loading of homogeneous marine cargo is considered. A mathematical formulation in terms of a mixed-integer linear program can be given. Still, the level of complexity turns out to be too high to perform full-scale computations. On the one hand, the reasons for this are the multitude of variables and constraints. On the other hand, feasible solutions to such problems may often be economically unacceptable or simply empty. Therefore, a heuristic is presented, according to which the relaxation of the limiting conditions influencing the solution’s feasibility and its economic profitability was parametrized. Under this heuristic, shifting the deadlines of selected orders is allowed. Also, the assignment of orders to vessels is separated from the allocation of vessels to piers in loading and unloading ports. The solution presented can be easily generalized by adding additional restrictions or features like indirect vessels, founding cost, or differentiation between materials.

Published: July 2022

We develop a model for asset liability management of pension funds, which is solved by stochastic programming techniques. Using data provided by the Bank of Uganda Defined Benefits Scheme, which is closed to new members, we obtain the optimal investment policies. Randomly sampled scenario trees using the mean and covariance structure of the return distribution are used for generating the coefficients of the stochastic program. Liabilities are modelled by remaining years of life expectancy and guaranteed period for monthly pension. We obtain the funding situation of the scheme at each stage, and the terminal cash injection by the sponsor required to meet all future benefit payments, in absence of contributing members.
Afrofuturism and Quest for Black Redemption in Nnedi Okorafor’s The Book of Phoenix
Authors: Sum Robert Kipkoech , Makokha Justus Kizito Siboe , Ndege Speranza
Published: July 2022

Nnedi Okorafor’s The Book of Phoenix follows the trajectory of many Afrofuturist texts in the exploration of the Black fortunes in the contested futuristic space. Using science fiction, fantasy, and speculative fiction, Okorafor appropriate futuristic space as a locale for negotiating the redemption of black bodies. She also contextualises the experiences of Africans or people of African origin in known world history. This, apparently, show that the futuristic space is neither detached from the past nor the contemporary period but rather it is an opportunity to map an optimistic future through a keen reappraisal of history from an Afrocentric perspective. This article uses a close reading of Nnedi Okorafor’s novel The Book of Phoenix to examine how prosthetically enhanced future is appropriated to re-enact the black struggle for redemption and relevance in the face of ruthless oppression through exploitation, dehumanisation, and slavery. The analysis is also guided by postulations of some prominent Afrofuturists like Mark Dery and Ytasha L. Womack. Data has been analysed using content and thematic analysis. This article finds that Afrofuturism can indeed portend optimism for black people in the sense that it utilises futuristic space to reconstruct the past and contemporary tribulations facing the black people in order to implement an ultimate solution and initiate the process of redemption. It can thus be concluded that The Book of Phoenix indeed lives up to Afrofuturist and Afro-optimist spirit by not only illuminating black challenges but also highlighting positive aspects of blackness like strength, resilience, humanity, and longevity. This article could benefit scholars in the field of postcolonial and diasporic studies by exposing the complex and dynamic nature of race, exploitation, and technology. It benefits the African/ Afro-diasporic literary studies as Afrofuturism is creating an impact in the domain of sci-fi which has traditionally been dominated by the West

La actuación de los ayuntamientos tras la declaración de inconstitucionalidad de la plusvalía municipal
Authors: Marín-Barnuevo Fabo Diego
Published: July 2022

La STC 182/2021 ha declarado la inconstitucionalidad del Impuesto sobre el Incremento de Valor de los Terrenos de Naturaleza Urbana (IIVTNU) con un controvertido fallo que no ha satisfecho prácticamente a nadie y que seguirá generando una gran litigiosidad.
Hasta el momento se han publicado muchos artículos en los que se analiza la sentencia desde la perspectiva de los contribuyentes, pero no se ha publicado prácticamente nada desde la perspectiva de la Administración local, que soportará los costes económicos de la declaración de inconstitucionalidad y los costes de gestión de los nuevos recursos y reclamaciones interpuestos.
En el presente trabajo realizamos un análisis de la situación desde la perspectiva de los ayuntamientos. Analizamos sus posibilidades de actuación tras la declaración de inconstitucionalidad de la plusvalía y la aprobación del Real Decreto-ley 26/2021, de 8 de noviembre, y planteamos los principales problemas a los que se enfrentan: los efectos de la declaración de inconstitucionalidad; el modo de resolver las reclamaciones en curso; el modo de resolver nuevos recursos que ignoran la limitación de efectos de la sentencia; la viabilidad de nuevas vías de impugnación que hasta ahora parecían improcedentes; y, finalmente, los problemas de interpretación y aplicación de la nueva regulación contenida en el Real Decreto-ley 26/2021.

Background. Women are commonly diagnosed with multiple sclerosis during reproductive age. There is need for disease control management during pregnancy, taking into consideration potential maternal and fetal risks. This review article aims to summarize what is acknowledged so far regarding treatment options of multiple sclerosis and outcomes in pregnancy, providing up-to-date information. Methods. In order to write this review a comprehensive literature electronic search for journal articles and guidelines regarding multiple sclerosis during pregnancy was undertaken. Results and conclusion. Multiple sclerosis management in pregnancy is a challenging issue. The use of disease-modifying drugs has improved both the course of the disease and the attitude towards pregnancy in patients living with multiple sclerosis. Pregnancy appears to have a protective effect on disease activity, particularly during the third trimester.

Moyamoya disease (MMD) is a chronic vasculopathy characterized by progressive bilateral stenosis and occlusion of the terminal portion of the internal carotid artery (ICA) and the presence of an abnormal vascular network at the base of the brain, termed Moyamoya vessels (MMV). The main presentations of MMD are ischemia and hemorrhage, and diagnosis is done via angiography. Cerebral events were reported in 5.1% of pregnancies of MMD diagnosed mothers, in Japan. In the case of MMD diagnosis due to cerebrovascular events during gestation, 34.7% of patients presented with an ischemic event, while 69.5% suffered from hemorrhage. During gestation, hemorrhagic events were found to occur mostly antepartum, after 24 weeks of gestation, while cerebral infarction peaked 3-7 days after delivery. No treatment has been found to halt or reverse the progress of the disease. Interventions focus on reducing the risk of stroke and cognitive disfunction as a result of ischemia. In the case of pregnant women suffering hemorrhage due to MMD, conservative treatment, as well as ventricle puncture and drainage were to be efficient, and did not severely impact the child. When diagnosed before pregnancy occurs, MMD under treatment does not pose a significantly increased risk of complications, compared to pregnancies in unaffected women. No evidence suggests that MMD is a contraindication for pregnancy.

Background and objective. Changes in grey matter of cortex and other parts of brain leads to increased pain perception in chronic low back pain (CLBP) patients which could be reduced by electrical application on these areas. The objective of the present review was to evaluate the efficacy of transcranial direct current stimulation (tDCS) alone as well as tDCS in combination with other interventions on pain in chronic low back pain patients. Method. PubMed and Cochrane search engines was used to locate the literature. The eligibility criterion for the study includes articles published in English language, published till March 2020 and the application of tDCS alone as well as in combination with other interventions on CLBP patients. Pain intensity was measured by visual analogue scale (VAS), numeric rating scale (NRS) or defense and veteran pain rating scale (DVPRS). Mean difference with 95% CI for the active tDCS, sham tDCS and tDCS in combination with other interventions was calculated. Result. 7 articles, with 427 patients, were included in the quantitative meta-analysis. The result showed statistically significant reduction in pain in tDCS alone as compared to sham tDCS Z= 1.93. P= 0.05 and insignificant reduction in pain in tDCS when used in combination with other intervention as compared to sham tDCS, Z= 0.72, P= 0.47 with heterogeneity of 84 % in the included studies. Conclusion. It can be concluded that there is significant reduction of pain in patients of chronic low back pain when tDCS is applied in isolation.

We present the power spectrum methodology used for the first-season COMAP analysis, and assess the quality of the current data set. The main results are derived through the Feed–Feed Pseudo-Cross-Spectrum (FPXS) method, which is a robust estimator with respect to both noise modeling errors and experimental systematics. We use effective transfer functions to take into account the effects of instrumental beam smoothing and various filter operations applied during the low-level data processing. The power spectra estimated in this way have allowed us to identify a systematic error associated with one of our two scanning strategies, believed to be due to residual ground or atmospheric contamination. We omit these data from our analysis and no longer use this scanning technique for observations. We present the power spectra from our first season of observing, and demonstrate that the uncertainties are integrating as expected for uncorrelated noise, with any residual systematics suppressed to a level below the noise. Using the FPXS method, and combining data on scales k = 0.051–0.62 Mpc−1, we estimate P
CO(k) = −2. 7 ± 1.7 × 104
μK2 Mpc3, the first direct 3D constraint on the clustering component of the CO(1–0) power spectrum in the literature.
Merger Rates of Intermediate-mass Black Hole Binaries in Nuclear Star Clusters
Authors: Fragione Giacomo , Loeb Abraham , Kocsis Bence , Rasio Frederic A.
Published: July 2022

Repeated mergers of stellar-mass black holes in dense star clusters can produce intermediate-mass black holes (IMBHs). In particular, nuclear star clusters at the centers of galaxies have deep enough potential wells to retain most of the black hole (BH) merger products, in spite of the significant recoil kicks due to anisotropic emission of gravitational radiation. These events can be detected in gravitational waves, which represent an unprecedented opportunity to reveal IMBHs. In this paper, we analyze the statistical results of a wide range of numerical simulations, which encompass different cluster metallicities, initial BH seed masses, and initial BH spins, and we compute the merger rate of IMBH binaries. We find that merger rates are in the range 0.01–10 Gpc−3 yr−1 depending on IMBH masses. We also compute the number of multiband detections in ground-based and space-based observatories. Our model predicts that a few merger events per year should be detectable with LISA, DECIGO, Einstein Telescope (ET), and LIGO for IMBHs with masses ≲1000 M
⊙, and a few tens of merger events per year with DECIGO, ET, and LIGO only.
On the Transmission of Turbulent Structures across the Earth’s Bow Shock

Published: July 2022

Collisionless shocks and plasma turbulence are crucial ingredients for a broad range of astrophysical systems. The shock–turbulence interaction, and in particular the transmission of fully developed turbulence across the quasi-perpendicular Earth’s bow shock, is here addressed using a combination of spacecraft observations and local numerical simulations. An alignment between the Wind (upstream) and Magnetospheric Multiscale (downstream) spacecraft is used to study the transmission of turbulent structures across the shock, revealing an increase of their magnetic helicity content in its downstream. Local kinetic simulations, in which the dynamics of turbulent structures are followed through their transmission across a perpendicular shock, confirm this scenario, revealing that the observed magnetic helicity increase is associated with the compression of turbulent structures at the shock front.
Are the Magnetic Field Directions of Surrounding Loops a Key Parameter for Confining a Solar Filament Eruption?
Authors: Ding Tao , Zhang Jun , Hong Junchao
Published: July 2022

Using high-resolution Hα data from the 1 m New Vacuum Solar Telescope, combined with multiband Atmospheric Imaging Assembly extreme ultraviolet observations and Helioseismic and Magnetic Imager light-of-sight magnetograms from the Solar Dynamical Observatory, we study a quiet-Sun filament eruption on 2019 November 1. During the erupting process, the filament was blocked by at least three sets of surrounding loops (L1–L3). The magnetic field direction of L2 is opposite to that of the top segment of the erupting filament. While the top segment contacted L2, a current sheet formed between L2 and the top segment. Then, magnetic reconnection took place, resulting in the destruction of L2 and the filament. On the other hand, the magnetic field direction of L1 is the same as that of the left leg of the erupting filament, and that of L3 is the same as that of the right leg. The left leg expanded eastward and met L1, then it stopped. The right leg expanded westward and collided with L3. It rebounded and finally stopped at the interaction region. These observations imply that the magnetic field directions of the surrounding magnetic structures are a key parameter for confining a filament eruption. While the field direction of a surrounding structure is the same as that of an eruptive filament, the filament is confined.

As part of the International Asteroid Warning Network's observational exercises, we conducted a campaign to observe near-Earth asteroid 2019 XS around its close approach to Earth on 2021 November 9. The goal of the campaign was to characterize errors in the observation times reported to the Minor Planet Center, which become an increasingly important consideration as astrometric accuracy improves and more fast-moving asteroids are observed. As part of the exercise, a total of 957 astrometric observations of 2019 XS during the encounter were reported and subsequently were analyzed to obtain the corresponding residuals. While the timing errors are typically smaller than 1 s, the reported times appear to be negatively biased, i.e., they are generally earlier than they should be. We also compared the observer-provided position uncertainty with the cross-track residuals, which are independent of timing errors. A large fraction of the estimated uncertainties appear to be optimistic, especially when <0.″2. We compiled individual reports for each observer to help identify and remove the root cause of any possible timing error and improve the uncertainty quantification process. We suggest possible sources of timing errors and describe a simple procedure to derive reliable, conservative position uncertainties.
Le processus d’implantation d’une nouvelle norme comptable : le cas de l’IFRS 15
Authors: Herriau Christophe , Lenormand Gaëlle , Touchais Lionel
Published: July 2022

Cet article analyse le processus d’implantation d’une nouvelle norme comptable à l’aune de la théorie des conventions. Des entretiens réalisés auprès de 18 groupes français soulignent l’importance de trois processus complémentaires dans la construction des pratiques comptables locales issues du déploiement de l’IFRS 15 : un processus d’interprétation de la norme, un processus d’imitation grâce auquel les acteurs convergent vers des pratiques communes via des logiques de place et via leurs pratiques opérationnelles et un processus de renforcement avec une volonté d’industrialisation des nouvelles règles. Cette recherche montre également que les conventions comptables sont fortement contraintes par les coûts d’implantation liés au déploiement d’une nouvelle norme comptable.
Repenser l’universel face aux identitarismes concurrents. Le cas de la compétition entre combats contre l’antisémitisme et contre l’islamophobie dans la France d’aujourd’hui
Authors: Corcuff Philippe
Published: July 2022

Pour commencer à reproblématiser la question de l’universel, cet article confronte une théorie politique critique à indices empiriques au terrain de la compétition entre la lutte contre l’antisémitisme et la lutte contre l’islamophobie dans la France du premier quart du XXI e  siècle. Après cette première polarisation manichéenne observée dans les débats publics français, il est conduit à traiter d’une autre opposition manichéenne : entre un identitarisme national-républicain et son double inversé « décolonial ». Ce qui permet de nourrir, finalement, la perspective d’un déplacement de l’universel en universalisable, en s’aidant notamment d’Hannah Arendt et de Judith Butler.
De la créolisation : questions ouvertes
Authors: Bistolfi Robert
Published: July 2022

Édouard Glissant, philosophe et poète, a célébré une créolisation depuis toujours active dans les sociétés humaines. Le passage d’un constat de l’inventivité passée des métissages culturels à une proposition politique pensée et motrice pour la société d’aujourd’hui est profondément novateur. En prenant place dans les débats de société, la créolisation-projet appelle une explicitation sur divers points. Ce qui se veut projet de sortie par le haut des impasses identitaires touche en effet à des sujets plus que sensibles. Cet article s’attache à identifier quelques-unes des questions qui sont à affronter : approche de l’Universel, conception de la laïcité, modalités d’intégration de la mouvance musulmane, fonction de l’espace public, organisation des luttes sociales pour l’émancipation, etc.
Du sentiment d’injustice aux processus de radicalisation. Réflexions sur les transformations des formes multiples de contestations politiques dans les « quartiers »
Authors: Marlière Éric
Published: July 2022

Cet article a pour objectif l’appréhension des répertoires de mobilisations politiques des jeunes dits « des cités ». Pour cela, il faut nous intéresser aux modes de vie de ces jeunes structurés depuis plus de trente ans, autour du chômage et de la précarité et des nouvelles formes de ségrégation. Cette situation engendre chez les jeunes une certaine frustration sociale se manifestant sous la forme d’un sentiment d’injustice plus ou moins diffus. Désormais en rupture de confiance avec les médias, les institutions et les politiques en général, certains jeunes adultes des quartiers populaires ont ainsi mobilisé des ressources nouvelles sur internet pour contrecarrer les discours médiatiques les disqualifiant en écoutant des personnages qui élaborent une rhétorique le plus souvent antisioniste, raciste, antiélitiste et « antisystème ». Des conférenciers et youtubeurs qui souhaitent renverser à terme les institutions en orientant un discours susceptible d’être entendu par les jeunes des classes moyennes en déclin et des jeunes des classes populaires éduquées mais marginalisées par les mutations de production.
Quand une radicalisation en cache une autre : sociologie des mouvances d’ultra-droite française
Authors: Settoul Elyamine , Bertout Emmanuelle
Published: July 2022

Si les phénomènes de radicalisation jihadiste ont fait l’objet d’une production scientifique exponentielle au cours de la dernière décennie, force est de constater que les courants d’ultra-droite constituent à l’inverse un champ d’étude relativement inexploré. Ce contraste est d’autant plus surprenant que la plupart des spécialistes s’accordent à affirmer que ces mouvances seraient en pleine expansion dans la plupart des pays occidentaux. Notre proposition vise à dresser une cartographie de ces tendances en soulignant leur diversité interne, leurs particularités idéologiques ainsi que leurs registres discursifs et communicationnels. Il s’agira notamment de mettre en lumière leur rapport au fait musulman ainsi que certains dénominateurs communs qu’ils peuvent entretenir avec les mouvances radicales d’inspiration jihadiste.

La propagande en faveur de la politique anti-palestinienne d’Israël a toujours fait feu de tout bois. Elle privilégie toutefois le chantage à l’antisémitisme. À l’en croire, l’antisionisme aussi serait une forme de haine des juifs. En France, depuis 2010, les inconditionnels de la droite israélienne ont ainsi essayé de mette hors la loi la campagne Boycott-Désinvestissement-Sanctions (BDS) : l’arrêt de la Cour européenne des droits de l’homme (CEDH) du 11 juin 2020 a porté un coup sévère à cette tentative. Entre 2017 et 2019, ils se sont livrés à une manœuvre politique plus ambitieuse : criminaliser l’antisionisme en tant que tel par le biais d’une loi. Elle a échoué. Pourquoi ?
Le heurt dans le catch ou le plaisir pris aux limites de la fiction
Authors: Morisset Thomas
Published: July 2022

Cet article propose une réflexion sur la spécificité de cet art en marge qu’est le catch. Prenant le contre-pied du célèbre article de Roland Barthes, son ambition est de penser une part sadique de l’appréciation de cet art qui ne se résume pas à la recherche de sensations fortes, mais qui constitue un véritable approfondissement sensible. L’objet de cette appréciation est le heurt, c’est-à-dire l’irruption d’une douleur factuelle dans un cadre fictionnel, déclenchant un jeu plaisant entre factualité et fictionnalité, rendu possible par la grande perméabilité de la structure fictionnelle du catch. L’article distingue trois types de heurts : la chute, les marques sur le corps et le sang.
L’esthétique des produits dérivés
Authors: Quilici Antoine
Published: July 2022

Des magasins Disney aux boutiques de musées, les produits dérivés sont désormais incontournables. En réutilisant une grande variété de formes et de volumes, ces phénomènes marketing semblent se faire l’écho d’une situation culturelle particulière pour laquelle un personnage de bande dessinée et un tableau de maître peuvent être imprimés sur un mug ou un carnet sans aucune distinction. Malgré ces goûts éclectiques, les produits dérivés semblent dessiner un savoir-faire spécifique, motivé à première vue par des raisons commerciales. Quelle est l’histoire des produits dérivés et comment pouvons-nous les définir ? En regardant les pratiques des concepteurs de produits dérivés et en les replaçant dans leurs contextes de vente, nous comprenons que la reproduction n’est pas la seule raison de leur succès. Une motivation décorative fait également partie intégrante de leur nature. Cet aspect des produits dérivés, qui appartient plus au champ esthétique qu’économique, nous offre des informations sur la place des arts appliqués dans notre société et sur leur traduction par le capitalisme contemporain.
Le conflit des normes à l’opéra
Authors: Pouradier Maud
Published: July 2022

L’opéra est un art né sous l’égide de deux idéaux concurrents : l’idéal de la musique grecque et l’idéal de la tragédie grecque. Cette ambiguïté originelle conduit à de fréquents conflits de normes sur le plan théorique, artistique et esthétique. Ce n’est pas la même chose de mettre en scène une œuvre musicale n’ayant qu’une relation analogique au livret représenté sur scène, et de mettre en scène une œuvre pleinement fictionnelle et théâtrale. Les critères d’évaluation d’une bonne interprétation vocale sont eux-mêmes conflictuels : faut-il privilégier des critères strictement musicaux, ou des défauts musicaux sont-ils admis au nom de l’interprétation théâtrale ? L’expérience esthétique de l’opéra est sans cesse sur le fil d’une hiérarchie indécise entre le registre visuel et le registre sonore. Sur un plan plus théorique se pose le problème du statut du chant opératique : fait-il partie du médium musical, ou a-t-il un statut fictionnel ?
Vivre avec l’architecture. Miterleben , corps propre et historicité des formes chez le premier Wölfflin
Authors: Gailhac Quentin
Published: July 2022

L’analogie classique entre les proportions du corps humain et celles des formes spatiales de l’architecture reçoit chez le premier Wölfflin une inflexion particulière que l’article s’attache à penser à partir de la dimension corporelle du concept de Miterleben , dans la mesure où le corps, au lieu d’être pensé comme une simple structure de proportions, est considéré dans sa dimension vitale, subjective et historique. Le corps propre ( Leib ) devient ainsi, non seulement ce qui rend possible l’expressivité des formes, mais aussi l’élément depuis lequel leur historicité doit être explicitée, celle-là même qui imprime, dans les formes mêmes, les représentations que les hommes d’une certaine époque se font de leur bien-être corporel et des conditions de leur épanouissement vital.
Wittgenstein : éthique et religion. De la « valeur » à « Dieu »
Authors: Halais Emmanuel
Published: July 2022

L’éthique de Wittgenstein, bien que difficile à saisir, est essentielle à sa philosophie. Afin de la comprendre, nous devons réfléchir tant à la valeur qu’au langage visant à exprimer, tandis que ce dernier échoue dans son entreprise même. Selon Wittgenstein, l’éthique est « surnaturelle » : une pleine saisie de la signification de ce terme exige une compréhension du caractère « accidentel » de tout ce qui est, i.e. qui tout ce qui appartient au monde. Nous verrons aussi comment Wittgenstein utilise la notion de « solipsisme », pour signifier l’intrication entre l’individu et la réalité en tant que tout. En ce qui concerne le langage, l’impossibilité de propositions éthiques, centrale dans le Tractatus logico-philosophicus , initie, dans la Conférence sur l’éthique , un regard réflexif sur la tendance à « affronter les murs de notre cage ». Ce n’est que sur cet arrière-plan éthique que nous pouvons comprendre la place de la religion chez Wittgenstein: Dieu (comme la valeur) réside en dehors du monde et il y a une identité entre « bon » et « divin ».
Generalized (edge-)connectivity of join, corona and cluster graphs
Authors: Wei Meiqin , Zhang He , Wang Zhao , Mao Yaping
Published: July 2022

The generalized $ k $-connectivity $ \kappa_k(G) $ of a graph $ G $, introduced by Hager in 1985, is a natural generalization of the classical connectivity. As a natural counterpart, Li et al. proposed the concept of generalized $ k $-edge-connectivity $ \lambda_k(G) $. In this paper, we obtain exact values or sharp upper and lower bounds of $ \kappa_k(G) $ and $ \lambda_k(G) $ for join, corona and cluster graphs.
Double decoupled network for imbalanced obstetric intelligent diagnosis
Authors: Zhang Kunli , Zhang Shuai , Song Yu , Cai Linkun , Hu Bin
Published: July 2022

Electronic Medical Record (EMR) is the data basis of intelligent diagnosis. The diagnosis results of an EMR are multi-disease, including normal diagnosis, pathological diagnosis and complications, so intelligent diagnosis can be treated as multi-label classification problem. The distribution of diagnostic results in EMRs is imbalanced. And the diagnostic results in one EMR have a high coupling degree. The traditional rebalancing methods does not function effectively on highly coupled imbalanced datasets. This paper proposes Double Decoupled Network (DDN) based intelligent diagnosis model, which decouples representation learning and classifier learning. In the representation learning stage, Convolutional Neural Networks (CNN) is used to learn the original features of the data. In the classifier learning stage, a Decoupled and Rebalancing highly Imbalanced Labels (DRIL) algorithm is proposed to decouple the highly coupled diagnostic results and rebalance the datasets, and then the balanced datasets is used to train the classifier. This paper evaluates the proposed DDN using Chinese Obstetric EMR (COEMR) datasets, and verifies the effectiveness and universality of the model on two benchmark multi-label text classification datasets: Arxiv Academic Papers Datasets (AAPD) and Reuters Corpus1 (RCV1). Demonstrating the effectiveness of the proposed methods is an imbalanced obstetric EMRs. The accuracy of DDN model on COEMR, AAPD and RCV1 datasets is 84.17, 86.35 and 93.87% respectively, which is higher than the current optimal experimental results.
Progressive participation
Authors: Bergemann Dirk , Strack Philipp
Published: July 2022

A single seller faces a sequence of buyers with unit demand. The buyers are forward‐looking and long‐lived. Each buyer has private information about his arrival time
and valuation where the latter evolves according to a geometric Brownian motion. Any incentive‐compatible mechanism has to induce truth‐telling about the arrival time and the evolution of the valuation.

We establish that the optimal stationary allocation policy can be implemented by a simple posted price. The truth‐telling constraint regarding the arrival time can be represented as an optimal stopping problem that determines the first time at which the buyer participates in the mechanism. The optimal mechanism thus induces progressive participation by each buyer: he either participates immediately or at a future random time.
Arquitectura y decoración de los monumentos funerarios de la necrópolis septentrional de Segobriga (provincia de Cuenca, Hispania citerior)
Authors: Cebrián Fernández Rosario , Trunk Markus , Hortelano Uceda Ignacio
Published: July 2022

Por primera vez, las excavaciones arqueológicas que se llevan a cabo en un sector de la necrópolis septentrional de Segobriga han documentado la disposición contigua de varios monumentos funerarios en uno de los costados de la vía principal de entrada a la ciudad. Los más antiguos se construyeron en época de Claudio y adoptaron formas arquitectónicas de raigambre itálica, entre las que destaca el tipo de aedicula sobre podio con las estatuas del difunto y los comitentes. Se aborda en este trabajo el proceso de monumentalización de las áreas cementeriales urbanas y la configuración de viae sepulcrales, que se desarrolló de manera simultánea al experimentado por la ciudad.
Respeto a las personas: un nuevo enfoque
Authors: Delgado Mansilla María Aurelia
Published: July 2022

Este artículo abordará el concepto kantiano de respeto a las personas desde la aproximación constructivista de la filósofa Carla Bagnoli. Su propuesta es una inspiradora y elaborada actualización del concepto, pero algunos aspectos sugieren dificultades. Se argumentará que estas tendrían que ver con puntos que necesitarían aclararse y con algunas tensiones, entendidas como derivadas de ciertas interpretaciones y redefiniciones, que también plantearían la necesidad de considerar una revisión de lo que constituye el estatus de una persona. Se señalará que estas tensiones atañen simultáneamente a la idea de agencialidad.
Kant y Rawls a la luz del ius ad bellum: razones para un debate en torno al cosmopolitismo
Authors: Díaz Anabitarte Aitor , Rincón González Manel
Published: July 2022

Con el fin de clarificar si Rawls es tanto o menos cosmopolita que Kant, realizamos un análisis comparado entre sus propuestas generales de ordenamiento de las relaciones internacionales. Asimismo, buscando aclarar la distancia exacta del cosmopolitismo respecto del pacifismo y del ius internacionalismo en el contexto del debate sobre la justificación de la guerra y de la paz, se analizan particularmente las propuestas de ius ad bellum de ambos autores. De un lado, fruto del primer análisis, se destacan ciertas coincidencias lógicas comúnmente inadvertidas entre los postulados de Kant y Rawls. Del otro, tras las conclusiones del segundo análisis y tomando como criterio las causas que ambos autores admiten como justas para la guerra, se aporta también una propuesta de tipo ideal de ius ad bellum cosmopolita.
