Dinámica de la cosmovisión y raíces culturales, del pueblo Q’eqchi’ (Qanawom, Q’eqchi’)
Authors:   Universidad de San Carlos de Guatemala, Tzoc Choc Juan de Jesús
Published: November 2023

La investigación en el paradigma del pensamiento complejo permite ver las realidades culturales de los pueblos desde categorías complejas, sistémicas, fractales y hologramáticas, asumiendo la cosmovisión como conocimientos con significados metafóricos que han permanecido en la tradición oral y en las construcciones ideológicas y significativas de que dispone el pueblo Q’eqchi’. Esta complejidad se refiere a la existencia de una estructura y organización del pensamiento ancestral, que es sistémico, de orden indivisible por ser un interfaz que muestra la realidad subjetiva e intersubjetiva como una dinámica viva, propia y auténtica. Hablar del método para abordar la cosmovisión ancestral, es tener la capacidad de ver más allá de lo que el ojo humano puede ver, es poder identificar, experimentar, comprender y describir mediante la hermenéutica y la argumentación teórica, la relación: humano – naturaleza – cosmos, unido a la práctica, la vivencia diaria de los conocimientos y saberes ancestrales, sustentados en los manuscritos y en la tradición oral de las comunidades. Este estudio muestra a la comunidad científica, que la cosmovisión es un modelo de pensamiento complejo y transdisciplinario, que aporta conocimientos importantes a los pueblos, además de proponer probabilidades de interpretación de la realidad para mejorar las visiones y los espacios de discusión, reflexión y enseñanza. La cosmovisión puede ser reconocida como una filosofía nativa, con grandes aportes que se ha mal interpretado desde las ciencias deterministas y reduccionistas con su rigor científico.

Authors: Khoirunnisa Novia , Rasji
Published: November 2023

This paper examines the consequences of the post-merger regime in Law No. 5/1999 concerning the Prohibition of Monopolistic Practices and Business Competition. This research uses the normative juridical method and comparative approach, comparing the American Antitrust Law which has successfully implemented the pre-merger notification with the Indonesian Business Competition Law which implements the post-merger notification. The results of this study indicate that the importance of implementing the Pre Merger Notification in the Law Concerning Prohibition of Monopolistic Practices and Unfair Business Competition is viewed in a comparison with the success of the Antitrust Law America and supported by the dynamics of globalization of the Industrial Revolution 4.0 which became a challenge for the Business Association Supervisory Commission. Thus, the regime change from Post Merger Notification to Pre Merger Notification is the right step in implementing a merger in Indonesia because Pre Merger Notification provides legal certainty and is also more efficient for business actors and KPPU as a preventive effort with the aim that the implementation of Pre Merger Notification will be carried out optimally in achieving the goal of fair business competition.

Authors: Adagba Terlumun , Abubakar Aliyu , Sabo Baba Abubakar
Published: November 2023

Concrete has a limited ductile range, poor tensile strength, and low crack resistance. Therefore, for concrete to function at its best, reinforcing is needed to compensate for these weaknesses. The aim of the study is to assess how the inclusion of baobab stem fibre affects the mechanical characteristics of concrete. Additionally, it sought to investigate the correlation between compressive and flexural strengths when baobab stem fibre is utilised as a reinforcement material. Concrete mixed with baobab stem fibre at volumes of 0.5%, 1.0%, 1.5%, and 2.0%, each with a fibre length of 50mm, was produced using a mix ratio of 1:2:3. The concrete had a constant water/cement ratio of 0.50 and was cured for the periods of 7, 14, 28, 60, and 90 days before testing. Test are carried out to determine how the inclusion of baobab fibre as reinforcement influences workability, compressive strength, and flexural strength. The findings indicated that higher volume fraction of baobab fibre in the concrete influence negatively its workability and compressive strength, but had a positive impact on flexural strength. The flexural and compressive strength results were analysed using Analysis of Variance (ANOVA) with Minitab 19 software. The results revealed coefficients of variation, with R2 values of 97.42% and 93.41% regarding the correlation between flexural and compressive strength, respectively, considering the percentage of baobab fibre volume and curing period. indicating, the percentage baobab fibre volume and curing age are useful predictors of the generated models. The results show that adding baobab fibres to concrete can enhance its performance, especially in terms of flexural strength.

Published: November 2023

The process of financial decentralization has had a significant impact on local budgets, making them independent of the state budget. This has created new opportunities for the development of territories through the implementation of specific projects that meet the needs of the community. However, the success of the viability of territorial communities depends most of all on the economic aspect. The introduction of martial law in Ukraine in February 2022 has significantly changed the living conditions of society as a whole. These conditions generate new challenges and tasks for the public and territories. It is important to find ways to adapt to new conditions, develop effective development strategies, and ensure economic sustainability. The implementation of real projects and economic initiatives aimed at supporting and developing the territories is becoming especially important. The article aims to substantiate the main problems in the financial resilience of territorial communities and to identify the main areas for improving the efficiency of attracting and using financial resources. The article argues that financial resources are the basis for the effective development and functioning of a territorial community. The authors examine the factors influencing the creation and operation of territorial communities and identify reserves of financial resilience of communities in the future. Theoretical studies related to the process of formation and development of territorial communities are analyzed. The article characterizes the capabilities of territorial communities, in particular, in terms of determining the investment attractiveness of objects on the territory, accounting for available resources and the possibility of their capitalization, use of labor resources, as well as the use of opportunities arising in the process of relocation of enterprises due to active hostilities in a large territory of the country. The authors prove the impact of migration processes on the possibilities of community development and functioning. The essence of submitting project applications for various competitions to attract additional funds to the community budget and thus form its financial resilience is substantiated. The main changes in the local budget process that arose under martial law and its impact on the development of territorial communities are outlined.

Sungai Balok, Pahang is one of the rivers that has been impacted by anthropogenic pollution in the surrounding area that contributes to increase the level of river pollution. The purpose of the study was to estimate the pollution levels using sediment indices include pollution load index (PLI), Enrichment Factor (EF) and Index of Geo-accumulation (Igeo). The sediment core samples were taken from five sampling points along Sungai Balok from upstream to downstream towards coastal area. The sediment samples were sliced into 2 cm aggregates from surface down to bottom of the sediment core. Then, the samples were oven dried, pulverized and digested using acid digestion prior to analyze using Inductively Coupled Plasma - Mass Spectrometry (ICP-MS). The average concentration of the elements in sediment core which are shows in the following order: As > Pb > Zn> Cr > Mn. It was found that the elements concentrations distribution varied between the vertical layer. The assessment of the degree of pollutant in sediment were done based on sediment pollution indices.
Citizen science expanding knowledge: a new record of the lizard Heterodactylus imbricatus (Squamata, Gymnophthalmidae) in south-eastern Brazil
Authors: Zocca Cássio , Barreto-Lima André , Daleprane Dulce , Ghilardi-Lopes Natalia
Published: November 2023

Through citizen science projects, like Projeto Bromélias, community members contribute valuable data on species diversity, notably those with low detectability like theHeterodactylus imbricatuslizard. A recent observation in the State of Espírito Santo (south-eastern Brazil), amidst coffee and eucalyptus crops, highlights the utility of widespread technology use in tracking and documenting wildlife. Such initiatives are especially beneficial for mapping the distribution of rare, endemic or endangered reptiles. Therefore, we advocate for more citizen science initiatives near protected areas, involving local communities.

We provide a new record for the speciesHeterodactylus imbricatus, a microteiid lizard of low detectability from the Atlantic Forest of south-eastern Brazil.Heterodactylus imbricatus(Rio de Janeiro Teiid) was recorded near the protected area "Reserva Biológica Augusto Ruschi" by a citizen volunteer who contributes herpetofauna records to the Bromelias Project (https://www.inaturalist.org/projects/projeto-bromelias).Heterodactylus imbricatusis a very poorly-known species in the localities where it occurs, probably due to its fossorial habit, genera's restricted occurrence range, habitat specificity and the absence of proper survey methods fitted to fossorial species, such as the utilisation of pitfall traps. By publishing the records of volunteer citizens, we hope that more people will contribute to increase the knowledge of biodiversity in the mountainous region of Espírito Santo State and expand our collective knowledge.

European islands are hotspots of biological and cultural diversity, which, compared to mainland, are more vulnerable to climate change, tourism development, uncontrolled land-use changes and the consequences of financial crisis. These drivers of change have increasingly resulted in severe impacts on socio-economic and environmental parameters. Projected climate, land-use and socio-economic change will impact on islands’ biodiversity, ecosystem services and, in turn, on the quality of life of island inhabitants. Even if the existing methods can adequately predict the abovementioned changes of the larger islands, this is not the case for small and medium-size islands, where there is a need for refinement. Although ecosystem services (ES) assessments have been carried out worldwide in different geographical areas, islands are still under-represented. Despite the recognised islands’ importance and vulnerability, efforts to date have focused solely on the pressures they face. Still, we know little about ES supply, flow and demand and their spatio-temporal variability, whilst integrated approaches that consider ES cross-island realms (terrestrial, marine and their interface) remain scarce. Even more under-represented are studies that explore the telecoupled relationship amongst islands and their mainland counterparts. Moreover, the current conceptual approaches guiding ES mapping and assessment need further refinement to account for the complex manifestations of nature and culture arising from peoples’ interaction with island spaces. This paper discusses the creation of a platform for coordinated interdisciplinary research on several aspects of mapping and assessment of ES in small and medium European islands in order to synthesise and strengthen the knowledge base for conservation of island realms and contribute to their sustainable development.
Syntaxonomic ranks, biogeography and typological inflation
Authors: Loidi Javier
Published: November 2023

To reduce the typological inflation observed in some territories where intensive phytosociological studies have been carried out and numerous descriptive papers have been published, an outline of the biogeographical amplitude of the different syntaxonomic ranks is proposed. Phytosociological classes are divided into five main vegetation clusters: 1. Zonal vegetation, determined mainly by climatic conditions; 2. Azonal coastal and saline vegetation; 3. Azonal rocky vegetation; 4. Azonal wetland and aquatic vegetation; 5. Highly disturbed anthropogenic vegetation. In each of these, the various ranks (class, order, alliance, association and subassociation) have a particular range which is expressed by the biogeographical territory in which they most likely occur. This area can refer to different respective categories: kingdom, region, province, sector and district. Some additional comments about typological inflation are made in order to focus on two phenomena: desire for fame and geographic drift.
The Digital Markets Act (DMA) and the Future of Transatlantic Relations
Authors: Tzogopoulos George N.
Published: November 2023

Le 1 er  novembre 2022, la loi sur les marchés numériques (DMA) est entrée en vigueur. Elle avait été proposée par la Commission européenne en décembre 2020 et approuvée par le Parlement européen et le Conseil en mars 2022. La loi sur les marchés numériques fait écho à la détermination de l’UE à façonner la nouvelle économie mondiale et à mettre en œuvre concrètement le concept de souveraineté numérique en proposant une réglementation renforcée qui affecte le fonctionnement des entreprises « Big Tech ». Cependant, elle crée également des défis dans une période où les États-Unis et l’UE intensifient leur dialogue sur les questions technologiques. Si les critiques américaines à l’égard du DMA sont relevées dans l’UE, l’ambition générale d’autonomie stratégique européenne, qui évolue dans la sphère numérique, n’ébranle pas l’unité transatlantique.
The European Union’s Governance Approach to Tackling Disinformation – protection of democracy, foreign influence, and the quest for digital sovereignty
Authors: Kachelmann Matthias , Reiners Wulf
Published: November 2023

Cet article présente une vue d’ensemble des caractéristiques de la désinformation à l’ère numérique, décrit l’évolution des efforts déployés par l’UE pour lutter contre la désinformation et fournit une analyse globale de l’approche de sa gouvernance en termes de politiques, d’acteurs et d’instruments politiques. Sur cette base, nous analysons sa compatibilité avec la quête de souveraineté numérique de l’UE. Les principales conclusions sont que l’UE a maintenu une approche particulièrement stable en combinant des instruments souples et fermes dans un cadre de corégulation qui implique des acteurs privés et publics. Nous concluons que l’interaction entre la nature de la désinformation, la configuration des grandes plateformes en ligne, la réglementation de l’UE et l’exposition aux influences étrangères crée un ensemble complexe de facteurs concurrents qui facilitent et brident la souveraineté numérique.

Published: November 2023

La Transition numérique verte et la gouvernance des données sont des composantes essentielles du développement soutenable, tant au Nord qu’au Sud. Cet article met en lumière l’importance de ces concepts et leurs implications pour la soutenabilité environnementale et le développement équitable. La Transition numérique verte fait référence à l’intégration des technologies numériques et des pratiques durables pour relever les défis environnementaux. Elle englobe des initiatives telles que l’intégration des énergies renouvelables, les réseaux intelligents, l’économie circulaire et la planification urbaine soutenable. La gouvernance des données, quant à elle, se concentre sur la gestion des données de manière responsable, sécurisée et transparente. Elle implique la collecte, le stockage, le partage et l’utilisation des données dans le respect de la vie privée et des considérations éthiques. Le Nord et le Sud sont confrontés à des défis et des opportunités distinctes dans la mise en œuvre de ces concepts. Le Nord possède une infrastructure numérique avancée, mais doit faire face à des préoccupations concernant la confidentialité et la sécurité des données. En revanche, le Sud est confronté à des limitations en matière d’infrastructures, mais peut dépasser les modèles de développement traditionnels en adoptant des technologies numériques soutenables. Il est essentiel de combler le fossé numérique et de garantir un accès équitable à la technologie et aux mécanismes de gouvernance des données. La collaboration entre le Nord et le Sud peut favoriser l’échange de connaissances, le renforcement des capacités et l’harmonisation des politiques. Une approche holistique intégrant la Transition numérique verte et la gouvernance des données est essentielle pour parvenir à un développement soutenable et inclusif à l’échelle mondiale.

L’échelle d’Heinrich dans sa version à 7 items a permis l’évaluation de la qualité de vie objective. Résultats : L’étude a été menée auprès de 107 patients. La prévalence de l’altération de la qualité de vie était de 32,7 %. Au terme de l’analyse multivariée, les facteurs protecteurs contre l’altération de la qualité de vie objective étaient le fait d’avoir une occupation et de résider en milieu urbain. Les facteurs de risques d’altération de la qualité de vie étaient la stigmatisation et les symptômes résiduels. Conclusion : les plaintes des patients sur leur mal être n’est pas à négligée lors des consultations. Il est important d’insister sur la psychoéducation des patients et famille, et de développer les dispositifs de réhabilitation psychosociale.

Diagnostics critiques. Maladies et pathologies sociales dans la Théorie critique de l’École de Francfort
Authors: Genel Katia
Published: November 2023

« On tend à définir aujourd’hui la Théorie critique de l’École de Francfort comme une philosophie sociale proposant un “diagnostic” portant sur des “pathologies sociales”. Or ces termes recouvrent en réalité une pluralité de démarches. Le propos de l’article est d’en interroger la continuité, depuis la position de Horkheimer et Adorno pour lesquels le mal social est plutôt identifié à la barbarie ou à l’irrationalité, les maladies psychiques de l’individu étant l’indice d’un tout social malade, jusqu’à l’analyse par Honneth des évolutions pathologiques ou manquées du social, qui font état d’obstacles à l’intégration sociale, en passant par l’analyse habermassienne des pathologies. L’article étudie plus précisément deux variantes très différentes de l’analyse du rapport entre le normal et le pathologique, selon que la pathologie est prise en un sens métaphorique ou plus littéral. Dans chaque cas, la question de la thérapeutique se pose différemment. »

La problématique de l’environnement-santé n’est pas nouvelle. De très nombreux auteurs (Beelen et al., 2014 ; DGS 2020 ; Zanobetti et al., 2008) se sont intéressés à l’effet – à plus ou moins long terme – sur la survenue de pathologies. Bien souvent, ces études travaillent à une échelle géographique nationale. Nous avons pris le parti de regarder les liens entre trois polluants atmosphériques à savoir le dioxyde d’azote, l’ozone et les particules (PM10) sur la survenue d’une exacerbation de bronchopneumopathies chroniques obstructives (BPCO) dans la ville de Nice, sur la période allant de janvier 2012 à décembre 2018, soulignant ainsi une accentuation des fragilités des humains évoluant sur ces territoires. Pour ce faire, nous nous sommes appuyés d’une part sur les données du PMSI et d’autre part sur des données recueillies par les différentes stations de surveillance de la qualité de l’air, provenant du réseau de surveillance de la qualité de l’air AtmoSud. Pour étudier ce lien statistique et ses conséquences, nous avons utilisé un modèle de régression de Poisson basé sur un modèle linéaire généralisé. Ce modèle a été essentiellement alimenté par deux indicateurs que nous avons construits. Le modèle de régression permet ainsi d’estimer le coefficient associé à notre variable explicative et de calculer un risque relatif. Ainsi, nous avons pu mettre en évidence un lien significatif entre deux de nos polluants et notre évènement sanitaire, à savoir la survenue d’une exacerbation de BPCO.
High Temperature Tensile Properties and Microstructure of Ni20Cr Alloy Fabricated by Laser Powder Bed Fusion

Additive Manufacturing (AM) brings about an array of modifications in microstructure with respect to conventional routes transforming mechanical performances. These new microstructure features depend on process parameters and especially on volume energy-density delivered by the laser on powder layer. Among the different alloys manufactured by AM, Ni-alloys exhibit high-strength at elevated temperature opening the way of fabrication of gas turbines and jet-engine parts. Ni-superalloys experience precipitation hardening due to the formation of γ′ and γ′′ phases leading to complex microstructures. To better study the influence of the AM microstructure on Ni-alloys mechanical properties, in particular at elevated temperatures, a theoretically monophasic and binary Ni20Cr-alloy manufactured by laser powder-bed fusion was studied in this work. Remarkable Yield Strength (400 MPa) and Ultimate Tensile Strength (UTS) (600 MPa) were observed at 500°C with hardly any loss of properties from room temperature, owing to the thermal stability of cellular dendrites till 700°C. Ductility drop was reported at 700°C due to anomalous brittle behaviour of Ni-alloys. Hardening behaviour vanished at 900°C signifying the deletion of dendrites, disappearance of dislocations, diffusion of Cr from dendritic walls and growth of oxides.

This study aims to investigate the influence of isothermal annealing on the residual stresses and fatigue properties of a 316L austenitic stainless steel, manufactured by the laser powder-bed fusion (LPBF), possessing a high density of 99.98%. Residual stresses were evaluated using the X-ray diffraction techniques. High-cycle fatigue tests were performed on cylindrical samples manufactured in both horizontal and vertical orientations, subjected to force-controlled axial fully reversed loading. Following fabrication, the samples underwent isothermal annealing in a furnace either at 600 °C for 120 minutes or at 900 °C for 30 minutes. Subsequently, the samples were machined to their final dimensions and electropolished to a mirror surface finish. Preliminary findings revealed that increasing the annealing temperature effectively reduced the surface residual stresses. However, this reduction did not lead to an improvement in the fatigue resistance of this nearly fully dense material in the high-cycle fatigue regime. Interestingly, the structure annealed at 600 °C exhibited a higher fatigue strength compared to the structure annealed at 900 °C, with no discernible difference between the printing directions. Fracture surfaces and microstructural features examined using light and electron microscopy revealed that cracking was primarily initiated at surface defects or slip bands. These results highlight the complex interplay between residual stresses, microstructure, strength, and fatigue behaviour of LPBF 316L austenitic stainless steel. Further analysis and investigations are required to fully understand the underlying mechanisms and develop strategies for enhancing the fatigue performance of additive manufactured components.

An overview of the additive/subtractive hybrid manufacturing (ASHM) research on three heat resisting materials – 18Ni-300 maraging steel, 316L stainless steel, and Inconel 718 (hereinafter 18Ni-300, 316L and IN718) – is provided to bridge key knowledge gaps and establish the respective process-microstructure-property relationships. The results examine validating the final surface roughness properties in the as-built and machined conditions in terms of the linear and areal parameters. Microscopic observations are also detailed to identify the influence of dry machining intermittent passes and/or laser conditions on microstructural features, as well as the bulk density. Mechanical stability assessment involved hardness measurement and tensile testing to evaluate the mechanical response of the materials built by in-envelope ASHM.

Metamaterials, including materials with regularly distributed porous structures, are currently a very intensively developing area of the technology industry. They bring a number of advantages compared to components produced in the classic way. The primary focus of such porous structures is to lighten the product and at the same time preserve its physical or mechanical properties, which subsequently conveys benefits in the form of saving material for the production of the device, and when used in aeroplanes or cars, they also save the amount of fuel consumed, so it can be said that such products and equipment are more user-friendly and environmentally friendly. There are many types of structures with different configurations, different types of basic cells, and different distributions of pores or their topology, so it is very important for the designer to know and decide which type of structure is most advantageous to use in the proposed product that will be subjected to a specific load. The article deals with the investigation of the mechanical properties of porous structures produced by the Direct Laser Metal Sintering (DLMS) method. It is focused on experimentally tested samples made of AlSi10Mg alloy with the Neovius structure, which were produced with four different relative weights. Results of quasi-static pressure testing at a crossbar speed of 10 mm/min (testing machine 250 kN Instron 8802 servo-hydraulic machine) point out that the trend of the influence of the relative weights on the First Peak Local Maximum best described by a second-order polynomial function.
