Efficient reliable scheduling and load balancing framework for cloud computing using Metaheuristic technique
Authors: Reddy Palle Ranadeep
Published: January 2024

Efficient load balancing and scheduling are crucial for effectively managing resources in cloud computing. Imagine a busy highway where we need to ensure that traffic is spread out evenly among different lanes to prevent any single lane from getting jammed. In a similar vein, we want to avoid overloading any one server in cloud computing by evenly distributing computational tasks and network traffic among multiple servers. This guarantees a smooth and solid activity of the cloud framework. This method makes things happen faster, increases the amount of work that can be done, and improves how resources are used. In cloud frameworks, ensuring things are accessible and can deal with blunders well depends a ton on spreading the responsibility successfully among various pieces of the framework. In spite of the fact that there are numerous ways of dividing the responsibility between servers or virtual machines, these strategies frequently face troubles in overseeing when errands are planned, how rapidly they finish, how much work can be taken care of, and how well mistakes are dealt with. In distributed computing, it's truly critical to fan out client demands uniformly among various pieces of the framework to ensure everything chugs along as expected. An effective method for dividing the responsibility between servers is significant for ensuring errands are done proficiently and assets are utilized well. The objective is to move things along quickly and make the most of available resources. A comprehensive yet adaptable strategy for balancing workload and task management in cloud computing is presented in this study. It utilizes a shrewd method to deal with the difficulties that accompany this interaction. The proposed strategy utilizes a changed Newton reconciliation method to deal with responsibility adjusting issues in the cloud. Likewise, it presents an exceptional sort of brain network called a multi-wavelet brain organization to plan undertakings dependably in distributed computing settings. The viability of this arrangement, tried utilizing Cloud Sim, will be contrasted with laid out benchmarks from the most recent examination.

Authors: RAUTARAY S K , SINHABABU D P
Published: January 2024

Field trials were conducted during 2003–07 to find out suitable rice varieties for rice-fish farming under organic nutrition in rainfed medium deepwater ecology at the experimental farm of Regional Rainfed Lowland Rice Research Station, Gerua, Assam. Among the rice varieties, highest grain yield (3.96 tonnes/ha) was recorded in Ranjit, followed by Durga, Piolee and Sarala. The combined direct and residual effect of kharif varieties on kharif rice-rabi rice sequence in terms of equivalent yield also revealed Ranjit as the best variety for kharif season followed by Durga and Piolee. In rabi season, long-duration variety Rupsundari performed better over the short-duration Vandana. Piolee showed better tolerance to natural submergence, which occurred for 10 days in 2004. Grain yield was highest (4.64 tonnes/ha) in the flood year due to inflow of nutrients (silt) with flood water. The fish yield was 472 kg/ha/10 months.
Estimation of genetic variability and implications of direct and indirect effects of different traits on leaf yield in bathua (Chenopodium album)
Authors: PARKASH CHANDER
Published: January 2024

The present investigations were undertaken to study variability and analyze the inter-relationship among five quantitative characters in 60 indigenous and exotic germplasm lines of bathua (Chenopodium album). All the traits revealed a considerable amount of variation among the germplasm lines. The extent of variation ranged from 12.4–435.3 g/plant for leaf yield. The phenotypic coefficients of variation were higher than genotypic coefficients of variation for all the characters. The estimates of genotypic coefficient of variation were higher for number of leaves/plant (46.75%), followed by leaf width (47.07%) and leaf yield/plant (46.43%). Heritability estimates (H2) were high (>80%) for all the five characters. In spite of high heritability values for all the traits, the expected genetic advance as per cent of mean ranged from 35.86 to 95.01. The genotypic correlation coefficients were in general higher in magnitude than the corresponding phenotypic correlation coefficients. All the characters were positively correlated with leaf yield but significant and positive correlation with leaf yield were shown only by plant height and number of leaves/plant. Path coefficient analysis revealed that number of leaves had highest direct effect (0.6279) on leaf yield, followed by leaf length (0.1728) and direct selection could be made for these characters for improving leaf yield. Plant height showed maximum positive indirect effect (0.2084) via number of leaves towards leaf yield hence simultaneous selection for number of leaves/plant and plant height can be made for the improvement of leaf yield in bathua.

Public health is a crucial issue in any society, and Argentina is no exception. Through the implementation of effective policies and programs, it seeks to promote and protect the health of the entire population, prevent diseases and improve the quality of life of citizens. This paper will analyze the importance of public health, a central theme in the movie "Sólo Gente". The plot of the movie takes place in a dystopian future where society is highly controlled and people live under constant surveillance. Through this futuristic setting, the film indirectly addresses several aspects related to public health. In the film, the government has exceptional control over people's health and uses advanced technology to monitor and control their physical and mental well-being. This depiction raises ethical and social questions about privacy and free will. It also highlights the importance of people having autonomy over their bodies and health decisions. In the context of public health, the film also shows how the state can use its power to prioritize certain aspects of health over others; another important aspect is the importance of equitable access to health care and how exclusion from the system can lead to negative consequences for those who do not have access to health services. In conclusion, the film "Just People" addresses several issues related to public health, such as privacy, individual liberty, health prioritization, health care systems, and equity in access to health services

Published: January 2024

Winter wheat is one of the most important crops in Ukraine, and modern varieties have the potential to produce high yields under favourable conditions. The realisation of the genetic yield potential of a variety is the result of a complex interaction of genotype and environmental variables. In order to find effective sources of resistance, a collection of winter wheat accessions of different ecological and geographical origin was studied. The research was conducted in 2017-2019 in the Right-Bank Forest-Steppe, and the analysis of plant resistance of the winter wheat collection of the National Centre of Plant Genetic Resources of Ukraine was tested against a synthetic infectious background of septoria, brown rust and smut as opposed to the natural background of powdery mildew, leaf yellowing (pyrenophorosis) and other root rot. The collection of 32 varieties was represented by 9 countries, most of them of Ukrainian origin. In the field, on artificial and natural infectious backgrounds, we identified varieties characterised by group resistance to pathogens of major diseases. The studies of adult plant resistance under conditions of infectious natural background and the use of the method of artificial complex infectious background have established that it is possible to investigate and identify sources of resistance to both individual pathogens and a complex of pathogens. As a result, no accessions were found to possess group resistance against the six pathogens presented. The selected varieties, Zdoba Kyivska, Vykhovanka Odeska and Feonia, can be used as sources of group resistance, which allows for excellent breeding efforts leading to the development of resistant wheat varieties. The selected sources are suitable for inclusion in breeding programmes as starting material for the development of modern high-yielding winter durum wheat varieties resistant to diseases and other environmental factors
Improving the Lease Deposit Guarantee System to Stabilizer the Lease Market
Authors:   Korea Real Estate Industry Society, Huh Ji Haeng
Published: January 2024

Despite the expiry of the lease contract, cases where lessee fails to get back the deposit or lease deposits from the landlord on time are increasing every year despite the expiration of the contract period. In particular, when the housing market is in a recession, disputes between lessors and lessees over the return of deposits are increasing, making the lease market uneasy. In contrast, the Housing Lease Protection Act protects the lessee by prescribing counter-force and preferential right to payment, and on the other hand, it allows the deposit money to be returned promptly by subscribing to a deposit refund guarantee through a guarantor institution. However, recently, while owning a house through gap investment, the non-return of the deposit due to the economic recession has increased rapidly, and fraud using the lease has occurred, revealing the limitations of the existing tenant protection system. Accordingly, this study examines the current deposit protection system and cases of deposit damage, and examines institutional limitation and problem that guarantee the return of deposit money. I would like to propose an improved deposit guarantee system. This study is one of the various improvement methods related to lease, and it is hoped that more improved plans will be derived through in-depth and diverse research.

Authors:   Korea Real Estate Industry Society, Moon Junghyun , Rhim Byeongjun
Published: January 2024

Some of the previous real estate generated due to the transfer of public institutes to provincial regions have not been sold yet, in spite of ongoing efforts to sell them since 2009. Based on such background, this study examined the restricting factors and means of dealing with previous real estate experiencing difficulties in sales. It was determined that controversy arising from the special benefits of easing the regulations on the use of the land can be coped with by reverting the increased portion of the asset values thereof to the local autonomous government based on the past incidents. In addition, the means of utilization of previous real estate for which the sales is restricted for qualitative reasons of the institutes can be sought by linking it with national policy projects and, since there existed such cases in the past, they were deduced as means that require review. Moreover, administration procedure of changing the plan for handling of such real estate mentioned the need for policy support through revision of relevant regulations such as new establishment of provision within the follow-up management methods, etc.

Published: January 2024

The occurrence of Benzotriazole UV Stabilizer-328 (UV-328) in different environmental and natural systems is of fast regular concern these days. In this current paper, we assessed the renotoxicity of UV-328 in zebrafish kidney tissues to know the chore of oxidative devilry in kidney and to recuperate the renotoxicity utilizing Dimethoxy curcumin (DiMC) supplementation. Grown-up zebrafish were exposed 55µg/L of UV-328 and DiMC supplemented through diet at 50mg/kg BW. Close to the completion of 28 days, renal tissues were examined for the responses of oxidative pressure, antioxidant status and histopathological changes. The results demonstrated that antioxidant enzymes such as, Glutathione (GSH) levels and the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione-S-transferase (GST) were all reduced in zebra fish kidneys treated with UV-328. Renal malondialdehyde (MDA) levels was brought prominently up in the UV-328 treated fish. All of the altered variables significantly returned to near-normal levels in the DiMC-supplemented group. Histopathological lesions, viz., hypertrophied glomerulus, cytoplasmic and nuclear degeneration, cytoplasmic vacuolization, degeneration of renal tubules were seen in UV-328 treated kidney of zebrafish which were actually reinforced in the DiMC treated fish. From our outcomes, it has been proposed that even at the low-level convergence of UV-328 exposure is malicious and to provoke oxidative insult, cell reinforcement exhaustion and kidney neurotic devilry in zebrafish and remediation with DiMC has been ended up being the better choice to conquer the harmful oppression prompted by UV-328.

Aşırı satın alma davranışı geçmişte daha çok tüketici araştırmalarında ele alınsa da, günümüzde psikolojik bir sorun olarak kabul görmektedir. Önceleri tüketici araştırmaları arasında daha çok yer bulan aşırı alışveriş davranışının psikolojik bir sorun olarak nasıl isimlendirileceği ve hangi sınıflandırma içinde yer alacağı konusuna dair tartışmalar alanyazında devam etmektedir. Bu sorunun bir dürtü kontrol bozukluğu, Obsesif Kompulsif Bozukluk (OKB) ve ilişkili bozukluklar ya da davranışsal bir bağımlılık olarak ele alınması seçenekler arasındadır. Geçmişte çeşitli isimlerle anılan bu sorun günümüzde alanyazında daha çok kompulsif satın alma ve alışveriş bağımlılığı olarak yer bulmaktadır. Fikir birliği olmayan diğer bir konu ise bu davranışın nasıl ölçüleceğidir. Sorunun hangi bağlamda ele alındığına bağlı olarak ölçüm aracının davranışın hangi boyutlarını ele aldığı da değişmektedir. Bu gözden geçirme çalışmasının amacı aşırı satın alma davranışının sınıflandırması, ölçümü ve ele alındığı bağlama göre geliştirilen ölçüm araçlarının özelliklerini incelemektir. Böylece klinikte ve satın alma davranışı araştırmalarında hangi ölçüm aracının tercih edilebileceğine ve buna bağlı olarak tedavi planının nasıl şekilleneceğine dair bir bakış sağlanmış olacaktır. Sonuç olarak aşırı satın alma davranışının doğasının ve hangi bağlamda gerçekleştiğinin ayrıntılı değerlendirilmesi gerektiği ve davranışın farklı bağlamlara göre farklı sınıflamalar içinde yer alabileceği söylenebilir.
Comprendre la notion d'engagement à travers le prisme de l'approche enactive
Authors: Martin Gaëlle , Nicolas Perrin , David Piot
Published: January 2024

L’engagement des apprenant·e·s est souvent pensé à l’aide d’approches nous invitant à comprendre cette notion en isolant certaines variables afin de déterminer les relations qu’elles entretiennent entre elles. Dans le cadre de cet article, nous proposons de l’approcher de façon systémique afin d’étudier les éléments favorisant un engagement générant des apprentissages à la fois significatifs pour les apprenant·e·s et les enseignant·e·s. Nous adoptons l’approche enactive (Varela et al., 1993) car cette dernière nous permet à la fois d’étudier la notion d’engagement du point de vue de l’acteur·trice et de ne pas mettre l’accent uniquement sur l’individu ou sur l’environnement, mais de comprendre l’unité qu’ils forment (De Jaegher & Di Paolo, 2008). Nous nous intéressons alors à ce qu’une conception enactive de l’engagement implique dans un contexte d’enseignement-apprentissage et réfléchissons particulièrement à la question de la responsabilité de l’engagement des apprenant·e·s. Puis, nous abordons la notion d’espaces d’actions encouragées (Durand, 2001, 2008) afin de réfléchir aux conditions favorisant, dans une perspective enactive, la construction d’apprentissages significatifs non seulement pour les apprenant·e·s, mais aussi pour les enseignant·e·s.

Published: January 2024

Os diferentes paradigmas de programação existentes se fazem necessários para resolução de problemas distintos, onde cada paradigma tem sua principal área de aplicação e suas vantagens e desvantagens ao ser aplicado na área em questão. Mas, ao unirmos dois paradigmas em um mesmo programa, obtemos uma maior flexibilidade e uma maior capacidade de resolução de problemas, pois podemos utilizar as vantagens de cada paradigma em conjunto, e não apenas um deles isoladamente. Nesse trabalho, foi desenvolvido uma DSL (linguagem de domínio especifico) em Haskell, para interpretação de programas Prolog, utilizando dois paradigmas de programação, o lógico e o funcional, mas que pertencem ao mesmo estilo de programação, o declarativo. Deste modo, tentamos minimizar as desvantagens de utilizar os paradigmas em conjunto, e espera-se maximizar as vantagens.

Published: January 2024

O Interferômetro de Mach-Zehnder (IMZ) é um dispositivo óptico que utiliza divisores de feixe e espelhos para criar interferência entre caminhos de luz ou partículas quânticas. A interpretação do IMZ usando o framework Qiskit da IBM envolve a modelagem e simulação desse interferômetro em um circuito quântico usando a biblioteca de programação de computação quântica. Nesse contexto, cada caminho do interferômetro é representado por um qubit, e os divisores de feixe e espelhos são modelados por portas quânticas que manipulam esses qubits. Neste trabalho analisamos 3 estudos de casos. A partir dos resultados das medições, pode-se analisar os padrões de interferência e obter informações sobre a diferença de fase entre os caminhos do interferômetro. Essa informação pode ser utilizada para medir deslocamentos de fase muito pequenos e para realizar experimentos de interferometria quântica.

Authors: Costa João Pedro de S. J. da , Dantas Mário A. R. , David José Maria N. , Silva Fernando de Almeida
Published: January 2024

Interoperability and data reduction have been proven beneficial to health and medical applications that deal with large datasets. Still, the conflicts between these qualities turned out to be a problem for their conciliation. This paper presents an edge-fog-cloud architecture that offers functionalities as a service. These functionalities can guarantee certain qualities depending on the necessities of the client, such as, in our case, interoperability and data reduction. With the use of context simulators, we found that it was possible to significantly increase the output of data delivered to the servers, and decrease the size of the data that transitions in the network and is stored in the servers’ databases, without interfering with the syntactic interoperability.

Published: January 2024

Este trabalho teve como objetivo analisar o desempenho do modelo de previsão numérica do tempo BRAMS em execução em um cluster AWS criado com o AWS ParallelCluster em diferentes mercados de instâncias, comparandoo com a execução no supercomputador Santos Dumont. Foi proposta uma metodologia para executar uma versão tolerante a falhas do BRAMS no mercado de Spot, onde as instâncias podem ser revogadas, embora ofereçam custos mais baixos. Os tempos de execução na nuvem foram satisfatórios quando comparados ao Santos Dumont. Em geral, a solução Spot reduziu o custo financeiro quando comparado ao uso de instâncias regulares On-Demand. Apenas em um cenário com muitas revogações, o que consequentemente aumenta o tempo de execução e o custo, a opção de usar o mercado On-Demand foi mais adequada.

Published: January 2024

O Alinhamento Múltiplo de Sequências genéticas é essencial para a área de bioinformática. Devido à sua complexidade exponencial, heurísticas são utilizadas. A mais popular é o Alinhamento Progressivo, com inúmeras ferramentas desenvolvidas ao longo dos anos. Entretanto, nenhuma consegue gerar sempre o melhor alinhamento, nem se sobressair. Assim, os cientistas são obrigados a escolher e utilizar mais de uma ferramenta. Ao invés de desenvolver uma nova heurística, este trabalho apresenta uma metaferramenta que avalia novas combinações de técnicas extraídas de outras ferramentas e coordena suas execuções eficientemente. A abordagem é capaz de alcançar speedups superlineares, mantendo, e por vezes melhorando, a qualidade dos alinhamentos.
Explorando a Variabilidade de Processo para Otimizar a Eficiência Energética em Servidores de Nuvem
Authors: Gonçalves Thiago dos S. , Beck Antonio Carlos S. , Lorenzon Arthur F.
Published: January 2024

O número crescente de núcleos em um único chip permite que servidores em nuvem mais poderosos explorem melhor o paralelismo no nível de requisições. No entanto, isso também leva a problemas imprevistos de potência, que podem acelerar o envelhecimento dos componentes de hardware e causar erros suaves ou até mesmo falhas. Portanto, o gerenciamento inteligente da dissipação de potência tornou-se crítico e imprevisível devido à variabilidade inerente do processo - uma vez que a potência máxima varia entre os núcleos, independentemente de operarem na mesma frequência operacional. Com base nisso, propomos PowerSaver, uma abordagem para otimizar a eficiência energética dos servidores em nuvem. PowerSaver distribui automaticamente a carga de trabalho entre os núcleos e aplica ajuste dinâmico de frequência dos domínios de core e uncore com base no comportamento das tarefas e na carga dos sistemas para reduzir a potência dissipada. Resultados em quatro arquiteturas multicore idênticas mostram que PowerSaver reduz a potência de pico em até 25.6% em relação ao escalonador padrão do Sistema Operacional Linux e em até 20.3% comparado ao HiMap, uma estratégia do estado da arte, com mínimo impacto no desempenho.

Published: January 2024

Seismic imaging applications are computationally costly, and the industry’s demand is continuously increasing due to the availability of better data, larger data, and the need for better resolution images. It means that the computational capacity needed tends to increase both in terms of FLOPS calculation and memory. Nowadays, many HPC clusters have nodes with multiple GPUs (e.g., 2, 4, and 8). In this paper, we investigate mechanisms and strategies for the data exchange (of the halo zones) of a finite differences grid of a wave simulator implemented in OpenMP. We compare the performance and programming effort of four data mapping mechanisms supported by OpenMP and CUDA. Our best strategy has achieved speedups of 3.87 on four V100 GPUs with NVLink.

Published: January 2024

Blockchain can be seen as a data distribution tool that guarantees immutability. As its use continues to expand across various sectors, it becomes increasingly important to investigate Blockchain’s performance concerning its different components and data originating from diverse application domains. This study explores the blockchain ecosystem, focusing on block creation, validation, network size, and partition processes. The chosen methodology involves utilizing Hyperledger Fabric for sharing medical information. To assess performance, Hyperledger Caliper was employed to collect throughput and latency. Among the key findings, we show that segregating the network into channels impacts the performance of Blockchain, mainly when the number of participating nodes increases. Sizes and timeouts to create new blocks influence the system’s performance. This paper contributes to developers by highlighting factors impacting blockchain-based applications’ performance.

A linguagem C++ recebeu novas abstrações de paralelismo com a definição das políticas de execução dos algoritmos da biblioteca padrão. Entretanto, a adequabilidade e o desempenho dessa alternativa ainda necessita ser estudado em comparação com outras alternativas bem estabelecidas. Portanto, o objetivo deste trabalho foi explorar a vasta gama de opções de recursos da biblioteca padrão C++ para avaliar a aplicabilidade e desempenho a partir de cinco kernels do NPB. Através dos experimentos em um ambiente multithreaded, foi constatado que a incorporação de estruturas de dados da biblioteca padrão, assim como a abstração para acesso multidimensional criada, não apresentam impacto notável no tempo de execução. Já os algoritmos com políticas de execução paralela demonstraram uma perda de desempenho estatisticamente significativa.

Approximate computing (AC) offers techniques ranging from application to circuit levels. AC techniques offer better performance at the cost of inaccurate results. A widely used software AC technique is loop perforation (LP). This paper presents an Instruction-Level LP (ILLP) approach that relies on approximate hardware instructions. We extended the ACCEPT compiler and SPIKE simulator workflows to generate and simulate applications with ILLP. We evaluated the technique comparing the results of precision, number of instructions, cycles, and energy consumption. ILLP achieves a 74.61% reduction in the number of instructions for the PI application, a 51.40% reduction in the number of cycles for the FFT, and an energy saving of 74.49% for the PI.
Securing Cities in the Global War on Terrorism: The Case of Oslo
Authors: Haugdal Jore Sissel , Lid Stian
Published: January 2024

In the global war on terrorism, cities worldwide have implemented a multiplicity of urban counterterrorism measures to protect buildings, public spaces, and citizens against terrorism. Since few previous studies have examined the historical development of urban counterterrorism measures in a concrete city, we examine the development of urban counterterrorism measures in Norway’s capital Oslo from 1993 to 2023. This chapter contributes with knowledge of the exogenous and endogenous factors that influence implementation of urban counterterrorism. Five different periods of urban counterterrorism are identified, which are associated with different potential targets and different forms of attack modus. During each period, new layers of urban security measures have been added while those already implemented persist. The conclusion is that there is a dissonance between the aims and realities of urban counterterrorism measures that impact the security and freedom of citizens. Future research should further investigate the impacts of urban counterterrorism on cities.
Exploring Host Factors of the Human Metabolism as Promising Targets for Dengue Treatment

Published: January 2024

The absence of specific therapy and the challenges posed by currently available palliative drugs, such as paracetamol, underscore the urgent need for targeting medications against dengue. Extensive research in the field of antiviral therapies has primarily focused on investigating viral proteins as potential targets. However, despite these efforts, finding an effective therapy for dengue fever remains a daunting task. Importantly, like all viruses, Dengue virus relies on human host proteins to enable infection. Recognizing this fact has prompted the consideration of host factors as viable targets for intervention strategies to combat the infection. This chapter aims to provide an overview of host-virus interactions during Dengue virus infection, emphasizing the importance of metabolic pathways, as well as molecular and cellular processes such as lipid metabolism, autophagy, apoptosis, and the immune system, which are critical for virus propagation. The main goal here is to expand the list of human factors that could serve as potential drug targets. Additionally, molecules that interact with these factors are explored for their therapeutic potential. This comprehensive exploration of host-virus interactions lays the groundwork for more effective dengue treatments. The molecules highlighted here hold promise as antiviral agents, and their inclusion in repurposing research could expedite the development of therapies for dengue fever.

The purpose of this study is to examine the effect of a music counseling program on the self-expression of elementary school students. One of the three fifth grade classes of D Elementary School in Y-gun, Jeollanam-do (a total of 23 students, 9 males and 14 females) was selected as the experimental group, and the other homogeneous class (a total of 22 students, 9 males and 13 females) was selected as the control group. The self-expression test was used as the test instrument. The experimental group received a total of 10 sessions of the music counseling program, while the control group received regular educational activities. To verify the effectiveness of the program, a t-test was conducted, and the students' reflections after each session and the researcher's observations were analyzed. The results showed that the post-test mean overall score of self-expression of the experimental group participating in the music counseling program was significantly higher than that of the control group, and the mean of the experimental group was significantly different from that of the control group in all three subdomains of self-expression (content expression, verbal expression, and nonverbal expression). In addition, the subjects' reflections and the researcher's observations after each session confirmed that the program had a positive effect on improving the self-expression of the experimental group. These results indicate that the music counseling program is effective in improving children's self-expression. This study is meaningful to veryfy that the music counseling program is effective in improving self-expression for general elementary school students, not just for special cases such as maladjustment, low-income class, and multi-culturalism.
Du commun et de l’universel ? L’expérience du texte utopique au siècle des Lumières dans le recueil des Voyages Imaginaires
Authors: Jacques Martine
Published: January 2024

En s’appuyant sur l’étude de quatre textes présentés dans Les Voyages imaginaires, somme éditoriale publiée par Charles Garnier entre 1787 et 1789, l’article s’interroge sur la représentation et la conception du commun et de l’universel qui s’en dégage pour le lecteur abonné. Il montre que si les textes semblent d’abord présenter comme idéal un modèle patriarcal classique, ils contribuent également à le mettre en question voire à le miner en inscrivant leur récit dans des structures narratives polygénériques. Le modèle utopique est alors confronté à l’histoire et à l’expansion coloniale autant qu’à la montée en puissance des libéralismes politiques et économiques. Inscrits dans chacun des textes, les débats fondamentaux sont également relayés par la structure même de l’anthologie qui les accueille. Si la somme ne propose finalement aucune définition figée du commun et de l’universel, rendant ainsi parfaitement compte des tensions internes aux Lumières, elle devient en revanche elle-même une utopie fondée sur l’acquis d’une lecture partagée qui modélise et permet d’expérimenter un en-commun qui, comme tous les autres, est à construire et reconstruire perpétuellement.
