Authors: Pliego Zoghbi Ana
Published: July 2024

El teatro, más allá de un sentido artístico y de entretenimiento, genera espacios de libertad y de cambio de la realidad en ámbitos y situaciones donde uno mismo no se espera que esta disciplina artística tenga cabida; como es el caso del Centro Penitenciario Madrid III, en Valdemoro. El objetivo de la presente investigación cualitativa fue analizar el impacto del teatro en las habilidades sociales, la autoestima y las emociones en el grupo de hombres que convive en el módulo 4, o terapéutico, del Centro Penitenciario Madrid III, a través del proyecto educativo LÓVA (La Ópera, un Vehículo de Aprendizaje). Y, además, poner en valor la importancia de actividades terapéuticas y culturales en la reinserción de los internos para adquirir herramientas que les sean útiles para vivir en sociedad. Tras dicha investigación, se pudo afirmar que el teatro, como herramienta transformadora, tiene un impacto positivo a nivel individual, y en consecuencia a nivel grupal, incidiendo significativamente en las habilidades sociales, la autoestima y las emociones de los hombres del módulo terapéutico del Centro Penitenciario Madrid III.

Changes in people's lifestyles have led to an increasing demand for a comfortable residential environment. This includes the availability of open space that is able to become a space for interaction between residents in a residential environment. In line with that, the need for green open space is also felt necessary to create a more natural and healthy living environment. In the residential environment of RT.003 / RW.034 Kel.Belian, the availability of open space or public facilities (fasum) has not been managed in an integrated manner.  Each fasum area is only in the form of empty land, pavilion area or field that does not have a clear allocation of use so that it cannot provide maximum benefits for the residents of the housing complex. Mentoring activities are carried out in formulating the management of public facilities so that they can function as community interaction spaces and green open spaces. The mentoring method is carried out by means of interviews, discussions, observations and social participation (Participatory Action Research/PAR) in which the proposer is part of the action, does not separate himself and melts into the situation of the community being assisted and works with residents in carrying out formulating the management of existing fasum land. This aims to empower the potential of the community and maintain the character of mutual cooperation between residents. As a result of the mentoring process, a new fasum management was formulated in which one fasum was designated as a green open space, one fasum that already had a pavilion was rejuvenated and built sports facilities and one fasum was used as a jogging track area and children's playground.

Mental disorders are a serious health problem because the number of illnesses continues to increase, including chronic illnesses such as schizophrenia which affect the thinking processes of sufferers. As a result, schizophrenic sufferers have difficulty thinking, managing emotions, and socializing with other people. Schizophrenia is a chronic, severe, and disabling disease, a brain disorder characterized by chaotic thinking, delusions, delusions, hallucinations, and strange or catatonic behavior. Hallucinations are one of the symptoms of mental disorders in which clients experience changes in sensory perception, feeling false sensations in the form of sound, sight, taste, touch, or smell. The aim is to analyze the results of the implementation of nursing care with interventions implementing strategies for implementing sensory perception disorders: auditory hallucinations in patients with schizophrenia. This KIAN aims to provide an overview of nursing care for schizophrenic patients with nursing problems of sensory perception disorders: auditory hallucinations and the nursing intervention carried out by implementing implementation strategies (SP). The implementation strategy is the implementation of nursing care standards applied to patients to reduce the mental nursing problems being handled. The aim of providing implementation strategies (SP) for sensory perception disorders: auditory hallucinations is for the patient to recognize the hallucinations they are experiencing, control them, and follow the treatment program optimally.

Authors: Nurhafizah Nasution  , Antonio Jaya Putra Pratama
Published: July 2024

Stunting is a condition where children under five fail to grow and appear short compared to their age. In Batam, the incidence of stunting in 2022 will still be high, namely 2.42%. This figure still needs to be reduced to reach the target of zero stunting by 2024. Many factors cause stunting, one of which is that families are not able to care for children under five independently due to lack of exposure to health information. One management that can be done is by providing health education. Nurses are expected to be able to make families independent through providing health education. The aim of this research is to analyze cases managed by providing health education to family members of stunting toddlers to increase family independence in the working area of the Kabil Puskesmas, Batam City in 2023.

Approximate Square and Square Root Calculation without Multiplication or Division for DSP Applications
Authors: Dina Mohamed Ellaithy
Published: July 2024

Square and square root functions are a fundamental step in many real-time digital signal processing applications such as image processing, signal processing, and filtering. The evaluation performance of these applications depends on the hardware algorithm used in the implementation of the square and square-root calculation. In this paper, we present an efficient algorithm that is capable of performing square and square root calculations without multiplication or division. Multiplier-less circuitry is introduced throughout the architecture to avoid the use of costly multipliers and dividers. The proposed square and square-root design exhibit good performance according to accuracy, latency, and power dissipation. Implementation and synthesis using Synopsys Design Compiler with a 90 nm CMOS process, 1.0 V supply voltage standard cell library, demonstrates that the proposed architecture leads to a 45% reduction in power dissipation while achieving higher accuracy when compared to the state-of-the-art approximate architectures. In addition, the proposed architecture is able to process the square and square-root calculation in 3 ns.

Published: July 2024

It is impossible to imagine our lives without the internet, but it has also meant that malicious acts such as phishing can be carried out anonymously. Phishers use social engineering or fake websites to trick their victims into giving them personal information such as credit card numbers, bank passwords and other sensitive information. However, the number of phishing attacks has increased significantly in the last year and current methods of detecting phishing are ineffective. This study focuses on identifying features of phishing websites, evaluating the best dataset and method for applying machine learning classification algorithms, and developing a prototype phishing detection system using the best classification algorithm model. In this study, the decision tree, logistic regression, and machine learning classification algorithm (k-nearest neighbours) were investigated. In this study, the waterfall methodology of system development life cycle (SDLC) was used. All approaches, strategies, tools and relevant theories were explored to provide an overview and understanding for this study. An extensive literature review was conducted to develop the model and problem statement. Data was collected through an open-source licenced website. In addition, the data was pre-processed before training and building the model to ensure that no noisy data was present. The parameters of the three models, K-nearest neighbours, decision tree and logistic regression, were adjusted to obtain the best possible model result. The models were then evaluated against the confusion matrix, accuracy, precision, recall, f1 score and decision tree to determine the best classification model for phishing and legitimate websites. The models are fine-tuned with the best parameters for each to achieve an optimal result for phishing detection. After evaluating each model, the decision trees were found to be the most accurate in classifying phishing websites with an accuracy of 95%. In the future, the system can be improved through different approaches such as Deep Learning and a fully developed web-based system that can be used in the real world.

Published: July 2024

In recent years, the market trends and acceptance of Energy Performance Contracting (EPC) have caught the attention of international specialists, especially in energy management fields. EPC projects are widely acknowledged as among the most efficient global strategies for improving Energy Efficiency (EE). However, EPC projects are plagued by numerous uncertainties, which increase project risk. The impact of risk factors and categories on EPC projects can influence the effectiveness and success of implementation in EPC projects. This paper applied the pre-recording systematic reviews and meta-analysis (PRISMA) approach to determine the primary data based on a few keywords, such as “risk or uncertainty and Energy Performance Contracting or Energy Performance Contracting project”. Based on advanced searching on SCOPUS and Web of Science (WOS), we found 32 selected articles (n=32). Expert scholars decided to develop three themes, which are (1) risk categories in EPC projects, (2) risk factors and categories in EPC projects, as well as (3) risk assessment methods in EPC projects. Here, the results summarise that the 19 risk factors were obtained and classified into six categories. In addition, risk assessment methods in EPC projects have been summarised. Consequently, the research findings can benefit academics and industrial practitioners in EPC projects.

In this study, we have described creating and deploying an online application designed to support university systems that promote healthy lifestyles. Based on the findings of small sample trials, several participants said they could easily access the program on their computer, tablet, or smartphone. Additionally, the participants stated that they extensively used the application's capabilities. Although participants' satisfaction ratings with the app were moderate, they expressed greater optimism over the program's overall potential for intervention. According to the results of our focus groups, users should receive further instruction on how to utilize the app to maximize their efficacy in subsequent research. The technical difficulties the research team encountered also emphasize how crucial it is to give appropriate time for large-scale trial studies. It is unclear whether eHealth interventions will contribute to the global physical activity pandemic in a timely and suitable manner, even though they have the potential to change particular participants' behavior. Physical exercise is a complicated behavior that can take place in a range of settings and be impacted by a number of environmental, social, and psychological elements. mental elements. It is recommended that future studies investigate the potential of technology-based intervention strategies to identify the most effective approach for bolstering university health-promoting systems, with the ultimate goal of influencing global community behavior.

Published: July 2024

The aim of this research is to minimize the travel time costs for transport cars starting from the warehouse in the sub-district, and delivering rice to 6 sub-districts in Pekanbaru only once and the transport car returning to the warehouse location. Minimizing travel time costs is carried out using the Hungarian method and the Branch and Bound method to solve the traveling salesman problem in interval numbers. The traveling salesman problem has interval costs because it depends on several obstacles experienced by the salesman, for example travel traffic constraints, transportation conditions, weather, and other costs. Then convert the interval numbers into trapezoidal fuzzy numbers using the fuzzification method. The results of the analysis show that using the Hungarian method and the Branch and Bound method to solve the traveling salesman problem at interval numbers can provide an optimal travel route for visiting 6 sub-districts in Pekanbaru using rice transport cars. This optimal route is expected to minimize costs and also save transportation time in rice distribution activities to the 6 sub-districts.

Published: July 2024

This work deals with a novel high step-up isolated DC-DC boost converter proposed with the help of a couple of inductors. At present, eco-friendly vehicles like Electric-Vehicles (EVs), Hybrid Electric Vehicles (HEVs), and Plug-In Electric Vehicles (PEVs) are effectively used as a feasible solution for achieving high efficiency over fossil-fuel operated vehicles, releases low emissions, global warming, noise-less, low maintenance, so on. In general, the vehicles like Internal Combustion Vehicles (ICE) are propelled by using fossil fuels like petrol, diesel, gasoline, and so on. But the efficiency is very low in this system because of the usage of hydraulic and mechanical components which requires more maintenance, high fuel consumption, toxic emissions, and so on. To overcome these challenges a novel Isolated DC-DC converter has been proposed adopted from Zeta converter with slight modifications. The proposed isolated DC-DC boost converters are used in many applications, due to high step-up gains, low duty ratios, high efficiency, low EMI loss, and low switch stress, so on. It has high power capacity, greater reliable features, and a modular, compact size best suitable for vehicular applications. Employing the high turns ratio of coupled inductor attains high voltage step-up gain as well as the secondary winding is in series with a switched capacitor for obtaining increased voltage level. Following is a detailed description of the proposed Isolated DC-DC converter: (a) The energy in connected inductor leaky inductors may be recycled, increasing overall system efficiency and reducing voltage spikes. (b) Using linked capacitor and switched capacitor methods maximizes the conversion gain ratio. (c) Creates an isolation channel while the solar PV arrays are not working, preventing electric risks to humans. The performance of the system is studied in the simulation environment.

The radio transient ASKAP J173608.2–321635, at the position (ℓ, b) = (356.°0872, −0.°0390), was serendipitously observed by The H i/OH/Recombination line survey of the Galactic center at three epochs in 2020 March, 2020 April, and 2021 February. The source was detected only on 2020 April 11 with a flux density of 20.6 ± 1.1 mJy at 1.23 GHz and in-band spectral index of α = −3.1 ± 0.2. The commensal Very Large Array Low-band Ionsophere and Transient Experiment simultaneously detected the source at 339 MHz with a flux density of 122.6 ± 20.4 mJy, indicating a spectral break below 1 GHz. The rotation measure (RM) in 2020 April was 63.9 ± 0.3 rad m−2, which almost triples the range of the variable RM observed by Wang et al. to ∼130 rad m−2. The polarization angle, corrected for Faraday rotation, was 97° ± 6°. The 1.23 GHz linear polarization was 76.7% ± 3.9% with wavelength-dependent depolarization, indicating a Faraday depth dispersion of

Big Bang Nucleosynthesis with f(R) Gravity Scalarons and Astrophysical Consequences
Authors: Talukdar Abhijit , Kalita Sanjeev
Published: July 2024

f(R) gravity is one of the serious alternatives of general relativity with a large range of astronomical consequences. In this work, we study Big Bang nucleosynthesis (BBN) in f(R) gravity theory. We consider a modification to gravity due to the existence of primordial black holes (PBHs) in the radiation era that introduce additional degrees of freedom known as scalarons. We calculate the light element abundances by using the BBN code PArthENoPE. It is found that for a range of scalaron mass (2.2 − 3.5) × 104 eV, the abundance of lithium is lowered by 3−4 times the value predicted by general relativistic BBN, which is a level desired to address the cosmological lithium problem. For the above scalaron mass range, the helium abundance is within the observed bound. However, the deuterium abundance is found to be increased by 3−6 times the observed primordial abundance. It calls for a high efficiency of stellar formation and evolution processes for the destruction of primordial deuterium, which is suggested as possible in scalaron gravity. A novel relation between scalaron mass and black hole mass has been used to show that the above scalaron mass range corresponds to PBHs of subplanetary mass (∼1019 g) serving as one of the potential candidates of nonbaryonic dark matter. We infer Big Bang equivalence of power-law f(R) gravity with PBHs that are detectable with upcoming gravitational wave detectors.
Determinants of astaxanthin industrial-scale production under stress caused by light photoperiod management of Haematococcus pluvialis cultivation
Authors: Bas Tomas Gabriel , Rengel José , Contreras Angela , Oliu Carolina Alejandra , Abarca Alejandro
Published: July 2024

Haematococcus pluvialis (Chlorophyta) is a microalga with the greatest capacity to generate pure natural astaxanthin with powerful antioxidant properties, through special cysts, in response to disruptions caused by stress conditions. This research tested the design of a prototype for applying artificial light photoperiods controlled by light-emitting diodes on an industrial scale for generating forced stress in H. pluvialis cells during two seasons of the year (winter and spring 2019) in the Coquimbo region in Chile. Three different culture structures were used for the four stages of the alga production cycle. Two containers, A and B, were used for the first and second culture stages, while a raceway (large pool) was used for the third and fourth culture stages. Experiments with four different photoperiods (PP) that represent hours of light:darkness were conducted in two trials (spring 16:8 and winter 18:6) and two for control (spring 11:13 and winter 10:14). In the experiment, an exponential increase of β-carotenoid was achieved, used in human and animal food for its health properties and as a natural colorant in the salmonids industry. Biomass and astaxanthin production under forced stress were measured with physical and chemical variables such as light intensity, temperature, pH, and dissolved oxygen. Results show that the spring culture showed a considerable increase of cysts and, therefore, of astaxanthin reservoirs, reaching a pigment production density of 276 g m-3, with the consequent increase in density of up to 22% more than the control PP.
Réflexions sur la polysémie et la relativité de la notion de contributivité en droit de la protection sociale
Authors: Isidro Lola
Published: July 2024

Centrale dans le champ de la protection sociale, la contributivité reste une notion peu étudiée en droit. L’analyse des références à la notion et des usages qui en sont faits en droit de la protection sociale aussi bien interne, européen qu’international révèle la polysémie et la grande relativité de la notion de contributivité. Au niveau interne, il s’en dégage une conception bien souvent restrictive conduisant à des oppositions trop tranchées, comme celle entre assurance et solidarité ou entre contributivité et universalité. L’observation du droit international et européen donne à voir une approche plus souple de la contributivité qui n’est pas sans avoir été source de tensions avec le droit français.
La problématique de la contributivité dans l’indemnisation du chômage
Authors: Freyssinet Jacques
Published: July 2024

La question de la contributivité n’est pas au centre de l’histoire de l’indemnisation du chômage. Les débats principaux ont porté sur d’autres enjeux avec d’autres concepts. Cependant, à certains moments, certains acteurs ou certains experts ont mobilisé le registre de la contributivité pour justifier des propositions de réforme tantôt au nom de l’équité, tantôt au nom de l’efficacité. Il est intéressant de comprendre quand et pourquoi la contributivité est invoquée. Le débat peut porter sur les contributions respectives des salariés, des employeurs et de l’État. Il peut concerner le rapport entre les durées et les taux de cotisation d’une part, les durées et les niveaux des droits à prestations d’autre part. Il peut aussi s’agir de tracer une frontière entre des prestations dites contributives ou non contributives. Le flou engendré par la polysémie de la notion ne doit pas faire ignorer la réalité des conflits à l’occasion desquels elle est mobilisée.
Les prestations familiales et leur financement jusqu’aux années 1940 : construction d’une assurance sociale singulière
Authors: Math Antoine
Published: July 2024

Revisiter l’histoire de la mise en place du système des prestations familiales permet de revenir sur son origine salariale et de s’interroger sur sa construction en tant qu’assurance sociale ou encore sur ses dimensions contributives. Ce détour montre qu’il n’est pas incohérent de financer des prestations familiales par des cotisations. Un système bâti sur la solidarité professionnelle peut viser explicitement la généralisation au-delà des seules personnes en emploi. Le développement du système des prestations a permis à une part de plus en plus importante des ressources des travailleurs d’être déconnectée du pouvoir discrétionnaire de l’employeur notamment à partir des années 1940. Ce « second salaire » et les cotisations sociales bénéficient d’une très forte acceptation, non pas malgré l’effacement du lien du droit aux prestations avec l’occupation d’un emploi, mais bien parce que ce droit est rapidement étendu au-delà des cotisants.
L’évolution de la politique familiale depuis 1950 revisitée à travers le rôle joué par son financement
Authors: Math Antoine
Published: July 2024

L’évolution du système des prestations familiales depuis 1950 est réexaminée à travers le rôle joué par son financement, et en particulier l’importance de recettes dynamiques affectées à un budget autonome générant des excédents comptables. Trois grandes périodes peuvent être distinguées à travers la façon dont les excédents de la branche famille de la Sécurité sociale ont été utilisés ou évités. Jusqu’au milieu des années 1970, les marges dégagées ont surtout servi à diminuer le taux des cotisations affectées à la branche famille au profit d’autres assurances sociales. Ensuite, et jusqu’à 2014, la branche s’est vue garantir des ressources évoluant de façon remarquable au même rythme que la croissance, y compris après la substitution d’une partie des cotisations par des recettes fiscales à partir du début des années 1990. La période entamée en 2014 marque une rupture avec, pour la première fois depuis quatre décennies, un très fort décrochage de la part des recettes dans le PIB et, concomitamment, une diminution sans précédent des dépenses.

Les réponses reposent sur un héritage historique et des considérations pratiques que l’on ne doit pas ignorer et suggèrent des évolutions pour que cet enseignement réponde aux besoins de formation des juristes d’aujourd’hui.
L’accès à l’enseignement en Afrique du Sud après l’apartheid
Authors: Philippe Xavier
Published: July 2024

La fin du régime d’apartheid en 1994 annonçait la consécration constitutionnelle des droits fondamentaux au nombre desquels le droit à l’éducation, l’égalité et les droits de l’enfant figuraient comme des droits à réalisation immédiate. La nouvelle démocratie sud-africaine s’appuyait sur un constitutionnalisme transformatif dont l’accès à l’enseignement constituait un principe matriciel pour la réalisation d’autres droits économiques et sociaux. Pourtant, malgré cette consécration, l’accès à l’éducation dans l’Afrique du Sud postapartheid semble avoir été insuffisamment au centre des politiques publiques menées depuis 1994. Si certaines avancées ont indéniablement été réalisées, le bilan d’ensemble reste sombre car les promesses d’un égal accès à l’enseignement et l’éducation n’ont pas touché suffisamment les plus défavorisés. Les conditions d’accès à l’enseignement mais également les capacités d’une majorité de Sud-Africains à pouvoir bénéficier réellement d’un statut leur permettant de participer à la vie politique, économique et sociale demeurent encore assez largement une illusion.
La Cour constitutionnelle fédérale allemande vue de France – quelques perspectives
Authors: Gaillet Aurore
Published: July 2024

Alors que la Cour constitutionnelle fédérale allemande fêtera bientôt ses soixante-quinze ans, son prestige et son rayonnement sont considérés comme sans pareil en Europe. L’article s’interroge sur sa perception « vue de France », en s’appuyant sur les regards de la doctrine, et en intégrant le résultat d’entretiens menés auprès de juges, d’anciens membres et de membres actuels du Conseil constitutionnel. Ces « vues de France » permettent de s’interroger sur les différences et rapprochements possibles entre ces deux institutions dont les spécificités structurelles se comprennent à la lumière du contexte historique de leur création et des cultures juridiques respectives. La perspective est en outre développée dans une direction européenne plus large : dans le cadre du « réseau européen des cours constitutionnelles », le rôle de la Cour constitutionnelle fédérale allemande est assurément considéré comme fondamental, pour sa jurisprudence – tour à tour saluée et critiquée – comme pour sa qualité de partenaire, avec laquelle le développement de relations étroites est particulièrement précieux, en nos temps de crise de l’État de droit.
Les femmes condamnées à mort par les tribunaux militaires allemands en France occupée (1940-1944)
Authors: Eismann Gaël
Published: July 2024

Les condamnations à mort de femmes ayant contrevenu à l’ordre allemand en France occupée représentent un phénomène genré minoritaire mais un fait social et politique majeur. Les différences sexuées qui le caractérisent s’expliquent par les spécificités de l’engagement féminin contre l’occupant, la stratégie allemande de préservation des relations avec les populations occupées et la permanence des normes de genre. Avérée, l’indulgence relative à l’égard des femmes est cependant sélective. Lorsque celles-ci transgressent radicalement leurs assignations traditionnelles ou que pèse sur elles le spectre de l’ennemi judéo-bolchevique, les juges militaires allemands ne les épargnent pas.

Using Unmanned Aerial Vehicles Equipped with Thermal Cameras to Survey a Known Population of White-Tailed Deer
Authors: Pfeffer Deanna G. , Foster Justin A. , Kinsey John C.
Published: July 2024

New technologies are emerging that may have potential for yielding more reliable population estimates for white-tailed deer Odocoileus virginianus than traditional manned aerial surveys. In a study conducted in a 116.55-ha enclosure in the Edwards Plateau ecoregion of Texas, USA, we tested the accuracy and precision of population counts by using an unmanned aerial vehicle equipped with a dual thermal–red green blue (heat detection and color video) camera to conduct a complete area count of a known, closed population of white-tailed deer. We flew surveys during 2–4 December 2019 in preprogrammed transects and replicated them three times, in both the morning and afternoon. Detection was higher during morning surveys, when we detected almost all deer that were present, compared with afternoon surveys. The accuracy and precision of morning surveys reported herein justify further research into the development of a method using this equipment for surveying large mammal populations in certain habitats.
Intersexual relationships in mandrills: dominance, sexual conflict and the influence of social integration
Authors: Smit Nikolaos
Published: July 2024

The conflict of evolutionary interests between the sexes is commonly imprinted in social dynamics and physical asymmetries between the sexes. In species that live in polygynandrous groups, male-biased sexual size dimorphism often allows males to socially dominate and sexually coerce females. Yet, smaller female size might allow females to escape from males and female philopatry might promote female-female social support allowing females to resist or retaliate against males. The study of such intersexual conflicts is highly relevant in mandrills (Mandrillus sphinx) as they form large polygynandrous groups and exhibit extreme male-biased sexual dimorphism in size and ornaments, higher social integration of females than males, and female coalitions against males. The set up of Mandrillus Project over a decade ago has offered a unique opportunity to study intersexual relationships of mandrills in their natural habitat. Here, I present a synthesis of some recent studies that used the long-term behavioural and life-history dataset of Mandrillus Project and documented patterns of sexual coercion and intersexual dominance in mandrills. These studies show that male mandrills are generally dominant over females and use sexual coercion to increase their mating success. However, female social bonds and social integration permit females to occasionally outrank certain males. Finally, and surprisingly, higher-ranking and more socially integrated females receive higher rates of male sexual coercion, highlighting the need for future research to shed light on the trade-offs between costs and benefits of mandrill sociality.
Miguel de Molina dans Ésta es mi vida (1952) de Román Viñoly Barreto : le cinéma, de concert avec la musique, ou les multiples possibles du vrai et du faux
Authors: Le Vagueresse Emmanuel
Published: July 2024

Nous souhaitons montrer ici comment le long-métrage de fiction argentin Ésta es mi vida de Román Viñoly Barreto (1952) est l’exemple d’une mise en scène filmique spécifique, inventive et sophistiquée, de l’art musical transsubstantié sur grand écran, coïncidant aussi avec la seconde carrière du chanteur espagnol de coplas (chanson et genre musical populaire espagnol, influencés principalement par le flamenco) Miguel Frías de Molina (Málaga, 1908–Buenos Aires, 1993), après des moments très difficiles vécus par ce dernier. C’est ce qui donne à l’écran un résultat à la fois étonnant et passionnant, et pas seulement pour les libertés prises par ce musical à propos de la biographie « réelle » de l’artiste. Des libertés que n’importe quel art a le droit de prendre, bien entendu, vis-à-vis de « la vraie vie ». On remarquera aussi qu’avec un tel film, on parvient à une sorte de « spectacle total », un peu comme Wagner le souhaitait avec ses opéras à Bayreuth, suivant en cela le projet de Gesamtkunstwerk – « œuvre d’art totale », justement, en allemand – élaboré par les romantiques allemands au xixe siècle. Ainsi, entre musique (et chant, danse) et cinéma, mais aussi jeu (voir les occurrences du jeu dans le film) sur les genres, Ésta es mi vida est une sorte de film hybride, entre miroirs ou reflets plus ou moins fidèles et mises en abyme de la même eau, à la limite de l’intermédialité, pour notre plus grand plaisir, et de spectateur et de chercheur.
Quand les textes et les sols se taisent : le cas de Cencelle (Tarquinia, Italie, ixe-xve siècles)
Authors: Stasolla Francesca Romana , Nardi Combescure Sara
Published: July 2024

Les résultats des fouilles archéologiques, comparés à l’iconographie et aux textes médiévaux, fournissent de multiples croisements permettant de mieux cerner la civilisation matérielle, dans la perspective d’obtenir une vision globale et évolutive. Si l’historien et l’archéologue ont longtemps minoré « les illustrations », ces dernières sont aujourd’hui prises en compte comme des sources documentaires à part entière. Une étude intégrant textes, images et résultats de fouilles s’avère nécessaire dans le cas de Cencelle, cité médiévale italienne. Cencelle fait l’objet de fouilles depuis plus de trente ans, et nous a fourni un nombre important de données archéologiques relatives à la vie quotidienne de ses habitants. Le Moyen Âge italien est notamment riche en sources iconographiques, qui renvoient aux différents aspects de la vie urbaine, ce qui fait de Cencelle un cas d’étude particulièrement intéressant. Le recours à l’iconographie nous permet ainsi de mieux cerner certains aspects liés au contexte social et économique de la cité, comme ses loisirs ou ses croyances. À titre d’exemple, les croyances liées aux rites funéraires seront évoquées à la fin de cet article.
Les écrits de Cratès de Thèbes selon Diogène Laërce
Authors: Gugliermina Isabelle
Published: July 2024

Pourquoi Diogène Laërce ne rend-il pas compte de toute la produc­tion littéraire de Cratès et en traite-t-il autrement qu’il ne le fait pour Antisthène et Diogène ? Plusieurs réponses s’avèrent plausibles : soucieux d’équilibrer les différentes parties de son ouvrage, il omet volontairement des textes qui consti­tueraient des redites par rapport à ceux qu’il a déjà cités ; choisissant Antisthène comme fondateur du cynisme, il passe sciemment sous silence des textes de Cra­tès qui, le rapprochant davantage de Diogène, mettraient en relief la place pré­pondérante de ce dernier au sein du mouvement cynique ; enfin, cherchant à produire un nouvel ouvrage d’historiographie de la philosophie, c’est à dessein qu’il néglige les sources étrangères à cette discipline.
