Restoring the morphology and functionality of dental arches affected by carious lesions and/or edentations using fixed prosthetic restorations has been a continuous challenge for dentists. Porcelain fused to metal prosthetic restorations using lost wax technique or modern digital methods have proven to be a useful tool in restoring aesthetics and mastication, aspects that lead to the social reintegration of patients. The natural aspect of the prosthetic restoration depends on the talent and inspiration of the dental technician as the art of layering of ceramic masses cannot be surpassed by new emerging technologies.

O ex-presidente Jair Bolsonaro colocou em palavras o projeto político prevalente durante o seu governo, que pode ser traduzido como liberal-conservador-autoritário. Este texto busca compreender se e de que forma esse projeto político se fez presente, considerando práticas amplamente consolidadas da democracia-participativa, fruto de projetos políticos anteriores. Neste estudo, o foco está nos sistemas existentes na política de assistência social – Conselho Nacional de Assistência Social (CNAS), conferências nacionais e Comissão Intergestores Tripartite (CIT) –, devido à relevância que esses fóruns apresentam para a implementação e a estruturação dessa política. Como framework analítico, foram utilizadas categorias propostas por Charles Tilly (2013) para se analisarem processos de democratização/desdemocratização: amplitude, igualdade, proteção e caráter mutuamente vinculantes das consultas. Acrescentou-se a esse modelo a dimensão formal e informal em que as mudanças ocorreram, bem como a pandemia de covid-19 como interveniente relevante em todo o processo. A conclusão aponta que, apesar de não ter consigo alterar as regras formais que formatam o sistema de participação, houve um processo de desdemocratização do campo, com perda relativa dos mecanismos de participação e coordenação federativa durante o governo em análise.

Neste artigo investigam-se os impactos socioeconômicos do desemprego em diferentes grupos de indivíduos e, de maneira especial, aborda-se a circulação familiar de bens e serviços durante a procura por trabalho. Para isso, examinam-se os vocabulários de 245 trabalhadores em entrevistas semiestruturadas realizadas pelo Instituto de Pesquisa Econômica Aplicada (Ipea) entre 2015 e 2016, no âmbito do projeto Radiografia do Brasil Contemporâneo. Os dados foram submetidos a uma técnica estatística denominada Classificação Hierárquica Descendente, produzindo quatro classes lexicais. Já uma análise fatorial de correspondência inseriu os léxicos em um plano cartesiano, evidenciando duas cisões, uma temática e outra pelo montante de recursos envolvidos. Os resultados opõem as experiências de trabalhadores empobrecidos, para os quais o desemprego vincula-se à disputa por necessidades básicas, e de grupos com acesso consolidado a recursos, cujos repertórios familiares voltam-se à prospecção por melhores empregos. A análise contrasta uma inserção laboral precária e outra que ocorre em trajetórias mais estáveis. Finalmente, testes qui-quadrado associaram essas classes lexicais a indicadores de sexo, raça e escolaridade.

Este estudo analisou a dinâmica da cadeia produtiva da soja brasileira, com o intuito de entender o posicionamento dos produtores/exportadores do setor, no que tange à produção, ao mercado externo e ao meio ambiente. Além disso, foram agregados à discussão o processo de certificação da soja por meio da adesão às normas voluntárias de sustentabilidade (NVS) e a relevância dessa nova forma de regulamentação de mercado. Realizou-se uma revisão bibliográfica sobre o tema. Assim, iniciou-se tal revisão com o mapeamento da cadeia produtiva da soja brasileira e a posição do Brasil no cenário internacional. Após isso, relacionou-se o papel das certificações no gerenciamento dos efeitos da produção sobre o meio ambiente. Para essa segunda etapa, foram coletadas informações relevantes de produtores, exportadores e empresas que certificam a soja brasileira. Salienta-se que apenas duas certificações se destacam nessa cadeia produtiva: a ProTerra e, principalmente, a Mesa Redonda da Soja Responsável (RTRS – em inglês, Round Table Responsible Soy). Os resultados trazem a importância da criação da moratória da soja no Brasil, que tem como foco a preservação da Amazônia, refletida pelo compromisso de não comercializar ou financiar soja produzida em áreas desmatadas nessa região. No que se refere à certificação, as entrevistas com produtores, certificadoras e associações demonstraram que esses agentes estão cientes da necessidade de adotar os certificados e da diversidade de opções disponíveis no mercado. Ademais, elucidam a importância de possuir a certificação, tanto para a preservação ambiental, quanto para acessar os mercados mais exigentes, como é o caso da União Europeia, e, com isso, conseguir obter um preço mais alto para seu produto.

Neste trabalho, visamos a aprofundar o debate sobre a inserção do Brasil no regime internacional de investimentos, realizando uma análise comparada entre o Acordo de Cooperação e Facilitação de Investimentos (ACFI) do Brasil e os tratados bilaterais de investimentos (TBIs) de China, África do Sul, Rússia e Índia (demais países do BRICS) com países africanos. Iniciamos com um panorama sobre as relações político-econômicas desses quatro países com os africanos. Logo, discorremos sobre a inserção de cada país do BRICS no regime internacional de investimentos e apresentamos as características dos modelos de TBIs utilizados com países no continente africano. Realizamos um levantamento quantitativo e uma análise qualitativa dos textos dos acordos, para identificar suas principais características. Adicionalmente, apresentamos a atuação desses quatro países do BRICS no sistema internacional de arbitragem e analisamos os casos envolvendo os países africanos e os países do bloco. Ao final, resgatamos as principais características dos ACFIs e realizamos uma análise comparativa entre os modelos utilizados pelos demais países do BRICS, apontando suas diferenças e semelhanças. Concluímos que, apesar de os países do BRICS impulsionarem reformas no regime internacional de investimentos, posicionando-se criticamente sobre os TBIs tradicionais, normalmente estabelecidos por países do Norte global no que tange às relações com países africanos, os quatro países do BRICS aqui analisados utilizam o modelo tradicional de TBI, reforçando suas regras e princípios. Nesse sentido, acabam por reproduzir tratados entre economias assimétricas, que garantem direitos ao investidor estrangeiro em detrimento do interesse público em áreas fundamentais para as sociedades, como meio ambiente, saúde, trabalho e estabilidade macroeconômica. Apenas o ACFI traz um modelo de acordo diferenciado, porém, ele ainda não foi realmente colocado em prática, para que seja testado, aperfeiçoado ou mesmo questionado quanto sua necessidade. Em nossa análise, o Brasil tem um caminho a percorrer e deve buscar promover investimentos com países africanos de forma equilibrada, garantindo que esses investimentos efetivamente contribuam ao desenvolvimento econômico, social e ambiental para as partes envolvidas.
A Proof of Concept Using BLE to Optimize Patients Turnaround Time (PTAT) in Health Care
Authors: Muthu Arumugam Ganes Raj , Muthaiyah Saravanan , Muthu Anbananthen Kalaiarasi Sonai
Published: July 2024

In 2022, Malaysia's Ministry of Health (MOH) acknowledged that government hospitals continue to face challenges in delivering high-quality patient care. A significant issue is the absence of a Real-Time Patient Location Monitoring and Tracking Solution, which prevents doctors from efficiently tracking patients within medical facilities. This lack of real-time tracking contributes to a decline in service quality, creating an urgent need for optimization in patient monitoring and tracking solutions. Implementing an effective tracking system can significantly enhance patient care quality, improve resource utilization management, and boost staff productivity, ultimately saving costs, time, and resources for hospitals. One critical area for improvement is the Patient Turnaround Time (PTAT), which refers to the duration a patient spends being processed at a hospital before being discharged. PTAT is currently prolonged in many hospitals due to the complex processes involved and patients becoming untraceable while waiting for their turn. To address these challenges, we have developed an Internet of Things (IoT) solution utilizing Bluetooth Low Energy (BLE) technology to optimize PTAT. This solution enables hospital staff to track patient movements and localize them in real-time. By using wearable devices, the system measures the distance from patients to various Access Points (AP) spread throughout the hospital based on the dBm value. This paper presents comprehensive experimentation for the Proof of Concept (POC) and pilot testing of this BLE-based solution. The results demonstrate the accuracy of using the Received Signal Strength Indicator (RSSI) to optimize patient turnaround times in hospitals. By implementing this BLE solution, hospitals can reduce the time patients spend waiting for treatment, thereby improving overall patient satisfaction and hospital efficiency. The ability to monitor patient locations in real-time will ensure that patients receive timely care, reducing the likelihood of them wandering off and becoming untraceable. This technology represents a significant step forward in modernizing patient care and streamlining hospital operations in Malaysia.
Students experience stories as lenses for sense-making of the transition to higher education
Authors: Lees Deborah , Van Zyl Andre
Published: July 2024

This study explored the experiences of seven first-year university students in Johannesburg, South Africa. Recognising storytelling as a lens to reveal identity, this study focused on student experience narratives as a tool to better understand their transition from school to university. It examined the narrated experiences of these students as a means to reveal their student identities. The qualitative study utilised a case study design type to address the research question: “What do first-year students’ transition narratives reveal about their emerging student identities?” This paper focuses on athematic analysis that was used as a tool to analyse participants’ narrated experiences. The analysis resulted in five broad themes, namely that student identities in their first-year journeys were formed and influenced by interpersonal experiences, intrapersonal experiences, pre-commencement institutional experiences, experiences of formal learning, and learning experiences beyond the classroom. Despite encountering multiple challenges in their new environment, the students derived benefit through capitalising on their personal strengths as tools to adjust to the demands of their new institution. These tools were crucial resources used by participants to adjust to and ultimately flourish in their first year.
Pedagogy with a heartbeat: The transformative potential of citizen science in education
Authors: Goldin Jacqueline , Suransky Carolina
Published: July 2024

Over the past few years, we have worked together in a citizen science project called Diamonds on the Soles of our Feet (see also Goldin et al. 2021, Goldin et al., 2023). In this project we engaged with 420 young learners in the Limpopo Province of South Africa. We came to see participating schools as collaborative ecosystems where young citizens become entangled with water through experiential encounters that make science alive and relevant. Through our engagement with citizen science, we experienced the transformative power of affect and the relevance of emotions in education as a social and political project. In our pedagogy we depart from the idea that human beings are separate from the biosphere, thus recognising the interdependency of all life forms on earth. We believe that keeping science education in laboratories and libraries affirms what Bozalek and Zemblyas (2023) call “privileged irresponsibility”. We propose that citizen science and its transformative potential can be one way to redress such irresponsibility. Through impactful encounters with human – nonhuman entanglement and the emotions which are evoked in this process, citizen science can create opportunities for responseability (Bozalek & Zemblyas, 2023), through teaching and learning with the heart. Such entanglement also resonates with relationality as the currency of care theorists. In the context of our citizen science work, caring for unfamiliar others is a form of non-humancentred care with unfamiliar water bodies in which the binary of inside-outside learning becomes porous as the geographies of water penetrate the classroom walls. In Diamonds on the Soles of our Feet, we noted how watery spaces and images move back and forth caring-with and through human bodies – waterbodies to school, school to waterbodies. The entanglement with the nonhuman resonates with Massumi’s (2015) notion of becoming where there is an unrolling of an event that is a becoming of two together.

The Effect of Age and Stellar Model Choice on Globular Cluster Color-to-metallicity Conversions
Authors: Hartman Kate , Harris William E.
Published: July 2024

The photometric colors of globular clusters (GCs) act as effective proxies for metallicity, since all normally used optical/IR color indices exhibit a nonlinear but monotonic relation between their integrated color and their metallicity. One color index, (g − z) or (F475W–F850LP), has been spectroscopically calibrated in several studies, providing leverage to define color-to-metallicity conversions for other indices. In this paper, building on the work of Hartman et al., we study the GC color-metallicity relation in more detail by testing the dependence of the relations on different suites of stellar models and different assumed GC ages. Though noticeable differences between models exist, we find that the net effect on the derived GCS metallicity distributions is small.
Carbon Isotope Fractionation of Complex Organic Molecules in Star-forming Cores
Authors: Ichimura Ryota , Nomura Hideko , Furuya Kenji
Published: July 2024

Recent high-resolution and sensitivity Atacama Large Millimeter/submillimeter Array observations have unveiled the carbon isotope ratios (12C/13C) of complex organic molecules (COMs) in a low-mass protostellar source. To understand the 12C/13C ratios of COMs, we investigated the carbon isotope fractionation of COMs from prestellar cores to protostellar cores with a gas-grain chemical network model. We confirmed that the 12C/13C ratios of small molecules are bimodal in the prestellar phase: CO and species formed from CO (e.g., CH3OH) are slightly enriched in 13C compared to the local interstellar medium (by ∼10%), while those from C and C+ are depleted in 13C owing to isotope exchange reactions. COMs are mainly formed on the grain surface and in the hot gas (> 100 K) in the protostellar phase. The 12C/13C ratios of COMs depend on which molecules the COMs are formed from. In our base model, some COMs in the hot gas are depleted in 13C compared to the observations. Thus, we additionally incorporate reactions between gaseous atomic C and H2O ice or CO ice on the grain surface to form H2CO ice or C2O ice, as suggested by recent laboratory studies. The direct C-atom addition reactions open pathways to form 13C-enriched COMs from atomic C and CO ice. We find that these direct C-atom addition reactions mitigate 13C-depletion of COMs, and the model with the direct C-atom addition reactions better reproduces the observations than our base model. We also discuss the impact of the cosmic-ray ionization rate on the 12C/13C ratio of COMs.
Fleeting but Not Forgotten: The Imprint of Escaping Hydrogen Atmospheres on Super-Earth Interiors
Authors: Rogers James G. , Schlichting Hilke E. , Young Edward D.
Published: July 2024

Small, close-in exoplanets are divided into two subpopulations: super-Earths and sub-Neptunes. Most super-Earths are thought to have lost their primordially accreted hydrogen-dominated atmospheres via thermally driven winds. We consider the global chemical equilibrium of super-Earths and the lasting impacts of their fleeting hydrogen atmospheres. We find that hydrogen is efficiently sequestered into the interior, oxidizing iron and endogenously producing ∼0.5%–1.0% water by mass. As the atmospheres of super-Earths are continuously sculpted by mass loss and chemical equilibration, they remain hydrogen-dominated by mole (number) fraction but become steam-dominated by mass, which may be observable with JWST for planets transitioning across the radius valley. One of the main effects of efficient sequestration of hydrogen into the interior is to produce an underdense bulk interior compared to that of Earth. We predict bulk densities of super-Earths to be ∼5.0 g cm−3 for a 1M
⊕ planet, which is consistent with high-precision mass measurements and also population-level inference analyses from atmospheric escape models.
A Model for Pair Production Limit Cycles in Pulsar Magnetospheres
Authors: Okawa Takuya , Chen Alexander Y.
Published: July 2024

It was recently proposed that the electric field oscillation as a result of self-consistent e
± pair production may be the source of coherent radio emission from pulsars. Direct particle-in-cell simulations of this process have shown that the screening of the parallel electric field by this pair cascade manifests as a limit cycle, as the parallel electric field is recurrently induced when pairs produced in the cascade escape from the gap region. In this work, we develop a simplified time-dependent kinetic model of e
± pair cascades in pulsar magnetospheres that can reproduce the limit-cycle behavior of pair production and electric field screening. This model includes the effects of a magnetospheric current, the escape of e
±, as well as the dynamic dependence of pair production rate on the plasma density and energy. Using this simple theoretical model, we show that the power spectrum of electric field oscillations averaged over many limit cycles is compatible with the observed pulsar radio spectrum.

Or, en cinquante ans, le contexte a considérablement changé, que ce soit dans la nature de l’information elle-même, dans les méthodes de gestion et d’accès, dans les outils qui mettent en œuvre ces méthodes, ainsi que dans les pratiques et les usages. Face aux mutations de leur écosystème, les compétences des professionnels doivent donc constamment s’ajuster. Bernard Jacquemin et Stéphane Chaudiron identifient cinq défis à relever : la mouvance Open Science , l’ouverture des données, l’IA, le web social, l’engagement éthique.

Modèle d’analyse de la place des femmes dans les métiers du digital et du numérique : l’influence du genre
Authors: Cornet Annie , Collet Isabelle , Wuidar Simon
Published: July 2024

Les femmes restent minoritaires dans les filières des STEM (Sciences, Technologie, Engineering, Mathématiques), notamment en informatique (10 % de femmes) * . Elles sont également largement sous-représentées dans les métiers liés aux technologies de l’information, au numérique et au digital. Notre communication propose un modèle pour analyser le positionnement des femmes dans les STEM et dans les emplois liés au digital. Le modèle élaboré se base sur deux axes d’analyse. Le premier axe dissocie les courants basés sur l’égalité et la non-différenciation F/H de ceux qui partent de l’hypothèse qu’il existe des différences genrées. Le deuxième axe porte un focus soit sur les impacts au niveau individuel (niveau micro), soit aux niveaux organisationnels et sociétaux (niveau macro). Le modèle proposé a été construit à partir d’une revue de la littérature managériale et scientifique, de l’analyse d’interviews ** de plus de 40 femmes impliquées des métiers du numérique et du digital, de l’analyse des politiques organisationnelles à partir de rencontres avec une dizaine de managers des services IT et de 10 études de cas d’entreprises. Nous proposons pour conclure, un tour d’horizon des bonnes pratiques menées à l’étranger et en Belgique et des actions menées par les entreprises et les pouvoirs publics dans de nombreux pays.
Crossing cubic Lie algebras
Authors: Al-Masarwah Anas , Kdaisat Nadeen , Abuqamar Majdoleen , Alsager Kholood
Published: July 2024

An interval-valued fuzziness structure is an effective approach addressing ambiguity and for expressing people's hesitation in everyday situations. An $ \mathcal{N} $-structure is a novel technique for solving practical problems. This is beneficial for resolving a variety of issues, and a lot of progress is being made right now. In order to develop crossing cubic structures ($ \mathcal{CCS}s $), Jun et al. amalgamate interval-valued fuzziness and $ \mathcal{N} $-structures. In this manuscript, our main contribution is to originate the concepts of crossing cubic ($ \mathcal{CC} $) Lie algebra, $ \mathcal{CC} $ Lie sub-algebra, ideal, and homomorphism. We investigate some properties of these concepts. In a Lie algebra, the construction of a quotient Lie algebra via the $ \mathcal{CC} $ Lie ideal is provided. Furthermore, the $ \mathcal{CC} $ isomorphism theorems are presented.
Notes on the generalized Perron complements involving inverse $ {{N}_{0}} $-matrices
Authors: Zhong Qin , Li Ling
Published: July 2024

In the context of inverse $ {{N}_{0}} $-matrices, this study focuses on the closure of generalized Perron complements by utilizing the characteristics of $ M $-matrices, nonnegative matrices, and inverse $ {{N}_{0}} $-matrices. In particular, we illustrate that the inverse $ {{N}_{0}} $-matrix and its Perron complement matrix possess the same spectral radius. Furthermore, we present certain general inequalities concerning generalized Perron complements, Perron complements, and submatrices of inverse $ {{N}_{0}} $-matrices. Finally, we provide specific examples to verify our findings.
Some zero product preserving additive mappings of operator algebras
Authors: Huang Wenbo , Li Jiankui , Pan Shaoze
Published: July 2024

Let $ \mathcal{M} $ be a von Neumann algebra without direct commutative summands, and let $ \mathcal{A} $ be an arbitrary subalgebra of $ LS(\mathcal{M}) $ containing $ \mathcal{M}, $ where $ LS(\mathcal{M}) $ is the $ ^{\ast} $-algebra of all locally measurable operators with respect to $ \mathcal{M} $. Suppose $ \delta $ is an additive mapping from $ \mathcal{A} $ to $ LS(\mathcal{M}) $ that satisfies the condition $ \delta(A)B^{\ast}+A\delta(B)+\delta(B)A^{\ast}+B\delta(A) = 0 $ whenever $ AB = BA = 0. $ In this paper, we prove that there exists an element $ Y $ in $ LS(\mathcal{M}) $ such that $ \delta(X) = XY-YX^{\ast}, $ for every $ X $ in $ \mathcal{A}. $
A topical VAEGAN-IHMM approach for automatic story segmentation
Authors: Yu Jia , Peng Huiling , Wang Guoqiang , Shi Nianfeng
Published: July 2024

Feature representations with rich topic information can greatly improve the performance of story segmentation tasks. VAEGAN offers distinct advantages in feature learning by combining variational autoencoder (VAE) and generative adversarial network (GAN), which not only captures intricate data representations through VAE's probabilistic encoding and decoding mechanism but also enhances feature diversity and quality via GAN's adversarial training. To better learn topical domain representation, we used a topical classifier to supervise the training process of VAEGAN. Based on the learned feature, a segmentor splits the document into shorter ones with different topics. Hidden Markov model (HMM) is a popular approach for story segmentation, in which stories are viewed as instances of topics (hidden states). The number of states has to be set manually but it is often unknown in real scenarios. To solve this problem, we proposed an infinite HMM (IHMM) approach which utilized an HDP prior on transition matrices over countably infinite state spaces to automatically infer the state's number from the data. Given a running text, a Blocked Gibbis sampler labeled the states with topic classes. The position where the topic changes was a story boundary. Experimental results on the TDT2 corpus demonstrated that the proposed topical VAEGAN-IHMM approach was significantly better than the traditional HMM method in story segmentation tasks and achieved state-of-the-art performance.

Published: July 2024

Diabetic eye detection has become a major concern across the globe, which could be effectively addressed by automated detection using a deep convolutional neural network (DCNN). CNN models have better detection and classification accuracy than other state-of-theart models. In this paper, a differential evolution (DE)-optimized CNN has been proposed for the single-step classification of diabetic retinopathy (DR) and glaucoma images. DE has been used to find out the optimized values of four hyper-parameters of CNN, i.e., the number of filters in the first layer, the filter size, the number. of convolution layers, and the number of strides. Simulation has been done using three publicly available datasets, and the accuracy obtained is 87.8%, 92.3%, and 88.7%, respectively, which outperforms other models. No other state-of-the-art model has used DE for hyper-parameter tuning in CNN models. Also, no other additional segmentation approach or handcrafted features have been used. The model has been kept simple to reduce computational costs.
Considerazioni sulle ville marittime dell’Istria meridionale
Authors: Bulić Davor , Matijašić Robert
Published: July 2024

Si analizzano i dati disponibili sulle ville marittime nell'Istria meridionale, che in termini quantitativi forniscono una base soddisfacente per la loro categorizzazione tipologica rispetto allo scopo dell'edificio, vale a dire la correlazione di pars rustica/fructuaria e pars urbana, ma anche per l'elaborazione delle tipologie di ville marittime secondo la planimetria, in parte condizionata dal loro contenuto, cioè dalla funzione. Esempi provenienti dall'Istria meridionale indicano anche che le ville marittime con contenuto residenziale predominante rappresentano spesso il centro del podere a cui appartengono anche edifici specializzati nella produzione di determinati prodotti, alcuni dei quali possono anche essere classificati come ville marittime.
Le devenir des villas maritimes dans l’Antiquité tardive : le cas de l’Étrurie méridionale
Authors: Lafon Xavier
Published: July 2024

Les villas maritimes, du moins certaines d’entre elles, font certainement plus que d’autres l’objet d’une occupation qui déborde largement les limites du Haut-Empire et se prolonge au moins jusqu’au Ve siècle. Le littoral de l’Étrurie méridionale, entre le Tibre et Civitavecchia, offre un cadre propice pour l’analyse du devenir de ces villas car on dispose pour cette zone de restes archéologiques conséquents, en particulier les deux villas d’Alsium qui font l’objet d’une attention particulière, même s’ils n’ont pas encore fait l’objet d’une enquête approfondie, et de documents littéraires, à commencer par le poème de Rutilius Namatianus, De reditu suo, qui témoigne vers 416 d’une poursuite d’activités. Les questions que l’on peut se poser portent sur la ou les fonctions nouvelles assumées (auberge, monastère etc.) par ces complexes de grandes tailles qui ont ainsi survécu alors que des entités plus petites avaient déjà disparu depuis longtemps mais aussi sur le maintien d’une certaine forme de villegiatura.
Port-la-Nautique (Narbonne, France) : une villa maritime en contexte portuaire
Authors: Sanchez Corinne , Carayon Nicolas , Cavero Julien , Andersch Goodfellow Patrick , Mathé Vivien
Published: July 2024

Le site de Port-la-Nautique, à 4 km au sud de Narbonne, au bord des étangs, est connu de longue date comme un des avant-ports de Narbonne antique. Les nombreuses découvertes subaquatiques témoignent de l’importance des échanges qui s’y déroulaient. À partir de 2011 de nouvelles recherches dans une dépression marécageuse permirent de vérifier la présence d’un vivier. Il s’avère être par son plan (bassin circulaire avec salle à manger centrale) et ses proportions (67 m de diamètre) l’un des plus importants du monde romain. Il correspond aux modèles de viviers d’agrément associés aux riches villae connues sur la côte tyrrhénienne. Ce vivier exceptionnel amène à considérer l’habitat exploré anciennement sur le plateau au-dessus du port de la Nautique comme une villa maritime. Des prospections géophysiques ont permis d’en établir un premier plan et les opérations de fouilles sont en cours.
Fuori da antichi stereotipi e moderne visioni
Authors: Federico Eduardo
Published: July 2024

In età augusto-tiberiana furono costruite sull’isola di Capri 12 villae, ognuna dedicata a una divinità dell’Olimpo. Villae così numerose e imponenti furono costruite su un’isola con un territorio molto piccolo, privo di spazi litoranei e facili approdi. Solo la villa di Palazzo a Mare presenta un quartiere marittimo, le altre furono costruite su colline e altipiani. Paradossalmente le villae dell’isola di Capri sono tutte maritimae, perché affacciate sul mare, ma solo una, Palazzo a Mare, ha contatto con l’acqua. Il caso delle villae di Capri mostra che molti dei pregiudizi antichi furono generati per la loro costruzione su alture, non sul mare, mentre non si ritrovano, tranne in un caso, gli elementi classici della villa maritima, come la piscina.
