Authors: Tejada Silvia , Cohen-Sánchez Amanda , Valencia Cruz José María , Box Centeno Antonio , Gil Vives Llorenç , Pinya Fernández Samuel , Sureda Antoni
Published: February 2025

Global change has a deep impact on the distribution and prevalence of diseases in fish, leading to the emergence of new pathogens. A recent observation on Ibiza Island in the Balearic Islands highlighted the presence of black spot disease linked to a digenean fluke belonging to the genus Scaphanocephalus in Xyrichthys novacula specimens. The study aimed at assessing the antioxidant and immune responses in mucus and spleen of X. novacula, that are infected by Scaphanocephalus sp. Two sites were selected, one devoid of the parasite and other with its presence. Fish were divided by severity of infection (low or high). Weight and size were measured, and mucus and spleen samples were obtained. As the infection was increased, the body index was worst and antioxidant enzymes activities and immunological parameters in mucus increased. However, the systems could not prevent lipid peroxidation. Also increases in immunological determinations were observed in the spleen. In conclusion, Scaphanocephalus sp. in X. novacula triggers an immune response and oxidative stress in the mucus as the infection is more severe. These changes are accompanied by a decrease in their body condition.
From a lovely coast to a designated bathing beach: steps, challenges, legislative framework
Authors: Efstratiou Maria Adamantia
Published: February 2025

Offering good quality bathing beaches to the public is a necessity faced by Local and Tourist Authorities of coastal areas. Recreation by the sea or inland waters provides multiple benefits to local communities: health, physical and social activities, the local economy through the attraction of tourists. The increase of population in the coastal zone has caused an increase in the demand of recreational spaces.These days a multitude of coasts used (or with a potential to be used) for recreational purposes are not designated beaches. The benefits of their inclusion in the lists of designated bathing waters are substantial, because the regular microbiological monitoring safeguards public health. Additionally designated, monitored beaches become visible to international tourists through the relevant sites (i.e. in Europe through the European Environment Agency). To cover this emerging need for new monitored beaches we set a framework of actions necessary to transform a coastal recreation area to a designated bathing beach, suited for use with no health concerns. In this systematic, analytical, step by step Coastal Zone Management approach, we guide and support the competent authorities to design and develop a listed bathing beach.
Economic valuation of coastal blue carbon stock’s dynamics. An study in NW Spain using land cover transitions and InVEST
Authors: Herves-Pardavila David , Loureiro Maria
Published: February 2025

Economic valuation of ecosystem services stands as a critical element in comprehending the benefits derived from natural capital and guiding policymakers worldwide. Among these services, the regulation of CO2 fluxes is paramount for climate adaptation and mitigation, prominently observable within Coastal Blue Carbon habitats as salt marshes. We conducted a case study of sea level rise impacts on Galician (NW Spain) salt marshes and their carbon pools from present day to 2050. First, we compute the physical damage from flooding, using a rule-based model to identify land cover transitions. Secondly, Coastal Blue Carbon model of InVEST software is deployed to quantify impacts on carbon sequestration and apply economic valuation through the social cost of carbon. Our results indicate that the consequences of sea-level rise are limited when compared with other processes as erosion, which need to be better understood and modelled. 11 tons of CO2 would be emitted to the atmosphere by 2050 due to sea-level rise, with damages valuated in 37 thousand €. Our approximation is useful for including the monetization of regulating services for cost-benefit analysis and coastal protection.
Coastal Landscape and “Disappearing” Territories
Authors: Ivona Antonietta , Privitera Donatella
Published: February 2025

The relationship between climate and tourism is very close, and this connection is even more evident for tourism in coastal areas. The various impacts of climate change have long been obvious in many destinations. In addition, like all sectors, also tourism contributes to the production and emission of greenhouse gases, with devastating consequences for certain areas. Through a case study, this contribution aims to reflect on territories that are disappearing due to climate change combined with excessive tourism. A new form of tourism, known as last chance tourism, has emerged as a result. In recent decades, warming in the Mediterranean has been much faster than in the rest of the world, causing serious territorial and economic consequences. Entire areas traditionally dedicated to tourism today have to deal with a drastic decrease in the number of tourists or, in some cases, an excessive increase in them to visit places with an uncertain future..
Visibility analysis in wetland protection processes
Authors: Martelliano Vito , Denaro Nicoletta
Published: February 2025

The environmental and ecosystem values of wetland are maintained through standardized methods, monitoring ecological ed ecosystems aspects like quality of water bodies, the presence or abundance of species and so on. However, protection initiatives sometimes prove to be insufficient in effectively reducing anthropogenic pressures like intensive agricultural areas, infrastructure, urban settlements and industrial sites. Their presence affects effectively and from a perceptive point of view the landscape of the wetlands. In order to reduce visibility fragmentations of wetlands landscapes, the introduction of the perception analysis in wetland conservation processes could guarantee the integral protection of unique value of wetlands landscape. The visibility analysis method is based on the visual perception: intervisibility maps are created using GIS tools the proposed methodology has been applied to the case study of the southeastern Sicilian wetlands, whose landscape value is highly threatened by human actions.
Sea level rise projections: risk and impacts on populations in the mediterranean basin
Authors: Martellozzo Federico , Randelli Filippo , Dalle Vaglie Matteo , Falaguasta Carolina
Published: February 2025

Extreme Sea Level Rise (ESLR) refers to the significant elevation in ocean levels driven by climate change and other anthropogenic and geophysical factors. This phenomenon poses a substantial threat to coastal populations, particularly as climate change accelerates the rate of sea level rise. Reducing greenhouse gas emissions and addressing climate change causes are essential to slowing ESLR and minimizing its impacts on coastal communities. However, achieving significant global reductions in GHG emissions is a complex, long-term endeavor. As a result, many coastal regions, and even some inland areas, will inevitably face the impacts of ESLR sooner or later, with certain areas being more vulnerable due to their land use and topography. Currently, numerous institutions have modelled ocean volume expansion at various geographical scales. This study aims to create geographically detailed datasets that depict the inland extent of ESLR impacts under future climate change conditions, focusing on the Atlantic coast of Europe and the Euro-Mediterranean basin. By integrating ESLR projections under IPCC 4.5 and 8.5 scenarios, our estimates reveal that ESLR poses a significant threat to coastal populations. The study identifies that between 2050 and 2100, ESLR could affect areas where millions reside, emphasizing the urgent need for adaptive strategies to protect vulnerable populations and mitigate the adverse effects of rising sea levels.
The European Charter for Sustainable Tourism (ECST) as a model of best practices and participatory governance. The case study of the Asinara National Park
Authors: Masia Mario Gesuino , Gazale Vittorio , Malvica Sonia , Pinna Nicoletta , Carboni Donatella
Published: February 2025

The European Charter for Sustainable Tourism (ECST) represents a voluntary management tool for protected areas that promotes the implementation of sustainable tourism for both the environment and local communities, as well as for all the stakeholders (e.g., firms, tourists); its principles emerge as an essential guide for designing policies respecting the environment and actively involving the local community. The present work focuses on the Asinara National Park (Porto Torres, Sardinia-Italy) as a case study of the ongoing application of the ECST (i.e., renewal phase of Phase I and initiation of Phase II). The aims were: (1) to identify the strengths and weaknesses related to confirming Phase I; (2) to isolate the motivations leading a firm to obtain the ECST certificate. Through a methodology involving official documentation analysis and the Park’s entrepreneurial landscape, results suggested a systemic vision of stakeholder engagement in creating a model for best practices to qualify the socio-economic network. Promoting participatory and inclusive governance could ensure a balance between sustainable tourism and environmental conservation on the Asinara island.
Fishing tourism in Tuscany: current situation and future developments
Authors: Massaro Andrea , Sartini Marina , De Carlo Francesco , Rossetti Ilaria
Published: February 2025

Professional fishery plays a crucial role in the development of the Tuscan economy. Currently, this sector involves more than 1500 people and 583 boats, producing around 11000 tonnes/year of seafood products. Fishery in Tuscany is a multifaceted sector with a solid cultural baseline that over the years has changed its own relationship with the sea. In the last decade, fishermen and consumers have become aware of dangers that threaten the marine environment and in particular fish stocks. For this reason, fishermen and their associations, assisted by fishery biologists, have decreased fishing effort and invested in other activities to integrate their income. Fishing tourism, for example, is a diversification of fishing activities and represent a sustainable activity for artisanal fishermen, combining environmental protection, maritime culture, an alternative profitability and a connection between fisheries and tourism. There are currently 47 active fishing tourism licenses distributed along the entire Tuscany coast (including islands), mainly concentrated in the ports of Livorno and Viareggio. These are principally small-medium sized boats operating with passive gear followed by trawlers. From interviews carried out with fishermen, fishing tourism is considered an important activity to reduce fishing effort without compromising income and to create new opportunities and networks.
Ecosystem services as support tool of urban planning activities in coastal areas
Authors: Palermo Annunziata , Chieffallo Lucia , Rispoli Natalia
Published: February 2025

In coastal areas, increased climatic and anthropogenic pressures contribute to the reduction of ecosystem services related to the biodiversity of natural capital. These dynamics make the coastal areas one of the most complex contexts in which to combine the needs of environmental protection and those that characterize the government of the territory. Given these assumptions, this research activity intends to define the “Blue Community” model. It is aimed at directing planning processes in the definition of the rules of local resources’ use increasing coastal ecosystem services. In order to guide this research, a Systematic Literature Review (SLR) on the role of ecosystem services in urban planning was conducted. The paper presents the first results of the SLR. In particular, quantitative analysis has made it possible to derive information relating to sources, authors and keywords, highlighting the growing recent interest the research topic. Instead, the qualitative analysis based on the adoption of a technique of cluster analysis has favoured the study of the interrelations between planning activities of the coastal settlements and the ecosystem services.

Monitoring Transformations of Urban and Natural Landscape in Mediterranean Cities by Promoting Landscape Setting Archetypes
Authors: Sopina Ana , Bojanic Obad Scitaroci Bojanna
Published: February 2025

The research phenomenon of the ‘urban and natural landscape relation’ as landscape setting of cities, testifies to 25 centuries of urban culture in the Mediterranean. The holistic understanding of the landscape relation as a multidimensional phenomenon and changeability process presents a challenge in application to spatial planning. The research hypothesis introduces landscape archetypes as a conceptualisation principle that integrate various research fields and embody landscape reality, representation, and change. The applied research method of literature review sets spatial planning, collective psychology, and art photography as the main research fields for establishing landscape setting and landscape transformation archetypes. These landscape archetypes are verified by comparing the Mediterranean cases of Livorno, Ancona, and Dubrovnik. The landscape archetypes aid in dealing with the complex nature of landscape relations by acknowledging the values found in every landscape. Spatial planning, collective psychology, and art photography contribute to raising collective and individual landscape consciousness and foster a holistic approach to monitoring landscape transformations.
The quarries in the coastal municipalities of western Liguria: reflections on landscape protection with a view to their recovery
Authors: Comino Lorenza , Lanza Simona Giovanna
Published: February 2025

The coastal landscape, of western Liguria, constitutes one of the most delicate territorial areas that has undergone the greatest transformations. The coastal processes of industrialisation and urbanisation, linked above all to seaside tourism, have induced radical transformations, linked to the railway development, which in the 19th century drew a strongly built coastal landscape, and allowed the development of industrial and commercial settlements. Among these activities, such as open-cast quarries, has contributed to the transformation of the landscape, due to its strong impact on the morphology of the territory. What we often read today as 'wounds' of the territory, have fed strategic sectors for the national economy (construction, infrastructure etc.) with motives that are no longer sustainable from an environmental point of view, and need to be 'healed'. In western Liguria, out of 224 disused quarries, 78 are currently reused for tertiary or industrial or artisan purposes, 64 are spontaneously renaturalised, 11 are restored to their natural state and 71 are abandoned without plans. Through the analysis of some case studies, , such as the Ghigliazza quarries in Finale Ligure, this work aims to draw attention to the role that landscape protection can play in governing and directing the choices of reuse of delicate situations from a landscape, environmental and economic point of view.
Archaeological markers below the lagoon waters
Authors: Costa Elisa , Lucarini Carlotta
Published: February 2025

This paper focusses on the documentation of some archaeological case studies in the northern part of the Venice lagoon, an extreme and at the same time vulnerable ecosystem. The study emphasises the challenges of working underwater in this environment and the necessity of incorporating both traditional and modern digital techniques. Through the use of different technologies, such as Multibeam Echo Sounder, topographic surveys with the total station and DGPS, and photogrammetry, it is possible to reach a high level of detail in the documentation and analysis of the archaeological contexts. The data management with GIS software allows an efficient and easier consultation and the effective dissemination of the research results. Thanks to the synergic use of these tools, it is possible to produce an entire overview of underwater archaeological sites, which implies enormous advantages for their understanding and analysis of archaeological markers. The methodology we tested in this highly complex environment turned out to be crucial also in monitoring the state of conservation and degradation of underwater archaeological heritage.
The Latium coast from Ostia to Circeo: settlement dynamics in a peculiar context
Authors: Jaia Alessandro Maria , Ebanista Laura
Published: February 2025

The contribution aims to investigate the settlement dynamics of the Latium coastal stretch of approximately 100 kilometres between Ostia and Circeo. This is a strip characterized by peculiar geomorphological and hydrographic features which have determined the outcomes of settlement dynamics starting from prehistoric times. After the protohistoric settlement process, also defined by the presence of watercourses and basins, the Latin cities developed in the coastal and para-coastal strip and found their economic basis on the control of the landings. Coastal basins and their landing places and watercourses are fundamental elements in the definition of economic processes and territorial control. The fundamental caesura of the settlement process for this area is 338 BC. The Roman conquest determined a series of dynamics that will be highlighted in the contribution proposed in the light of the relationships of the urban centres with Rome and with each other. Finally, an example on the settlement dynamics of the southernmost district is presented. It is the area historically known as Palus Pontina characterized by a greater thinning out of settlements and by peculiar dynamics.

Authors: Karadöller Beril , İmren Caner , Koçel-Erdem Zeynep
Published: February 2025

The ancient city of Perinthos (Marmaraereglisi/Tekirdag/Istanbul), where researched with a systematic multidisciplinary archaeological project were initiated by the Ministry of Culture and Tourism in 2021, has the potential to accommodate both marine and land-based multidiscipline studies in a comprehensive approach. To investigate the traces of archaeological remains, an integrated geophysical survey was designed. As part of the project, a comprehensive multi-beam bathymetry study was carried out in the city's offshore zones, while geophysical studies were carried out on land. The bathymetry study aims to model and investigate the detailed seafloor morphology of the coast of the Perinthos. The seafloor morphology modelled using high-precision data gave us a unique opportunity to investigate the mysteries of the ancient city of Perinthos. Multi-beam bathymetry data in over 1000 hectare acquired with 400 and 700 kHz central frequency sensors. Throughout the data processing procedure, the ¨International Hydrographic Organization Standards for Hydrographic Survey¨ were adhered to. Finally, morphological imagery of the seafloor was obtained. The resolution of these images, varies between 10 cm and 1 meter depending on the depth. This study is a significant contribution to the high-resolution identification of ancient cultural heritage through the multi-beam bathymetry in marine archaeological sites.

Authors: Di Paola Gianluigi , Dilauro Grazia , Caporizzo Claudia , Rosskopf Carmen M.
Published: February 2025

Coastal areas characterized by sandy shorelines are among the most dynamic environments and subject to deep and rapid changes over time under the influence of natural and anthropic factors. Therefore, reconstructing the geomorphological and anthropogenic evolution, current state and possible near-future trends of a sandy beach is essential for deepening the understanding of its potential future development and better outlining measures for its sustainable management. Therefore we have examined the coast of the Molise Italy, which is predominantly made of sandy shorelines and characterized by widespread anthropogenic impact mainly due to tourism and the presence of hard defense structures. This coastline has been continuously monitored. Field measurements mainly concerned shoreline and dune front positions along with sedimentary and morpho-topographic features of the backshore/foreshore zones and the submerged beach up to the closure depth. Drone survey campaigns in 2019-24, carried out the creation of digital terrain models and detailed evaluations of recent morpho-topographic changes of the beach-dune systems. The combination of all validated field survey methodologies, along with the planned campaigns for the future, represent the monitoring plan outlined for the Molise coast aimed at defining future action strategies to support its sustainable development and the mitigation of the effects associated with the ongoing climate change

Coastal dune systems have been significantly altered due to erosion from environmental and human factors, and nature-based solutions have become important in restoring these ecosystems in the face of climate change. The el Cortal de la Devesa beach (Gulf of Roses, NE Spain) has been the focus of such nature-based solutions with the installation of sand fences. Two campsites along this beach have implemented contrasting integration strategies over time. The Northern campsite has defined its boundaries and regulated beach access, while the Southern campsite did not. This study aimed to develop high-resolution (10 cm) digital elevation models to quantify changes in sediment retention and dune height both pre and post construction of the fences, to assess differences between the campsites. Results indicated the Northern site had higher overall values in average height, maximum height and volume of sand dunes than in the Southern site. Also, a porosity of 50-60% proved 85% efficient in this context. This study contributes objective data that highlights the potential role that tourist-recreational sites play along coastlines in climate change resilience.
Cliff Failure Processes and Longshore Dispersal of Sediments, Vrgada Island (Croatia): Input from SFM Photogrammetryand Sediment Characteristics
Authors: Pikelj Kristina , Furcic Nina , Marković Frane
Published: February 2025

The coastal cliff on the Vrgada island is developed in Pleistocene aeolian-alluvial deposits which are subject to constant erosion. Digital Structure-from-Motion photogrammetry has been used to record and monitor the erosion of the cliff most of which occurs in the form of rockfalls. As a result, an L-shaped beach has formed. The eroded material is reworked and partially washed away by rain and waves. The prevailing waves are generated by the Scirocco wind (SE, and they transport the eroded material from the eastern to the north-western part of the beach. This transport direction is confirmed by heavy mineral analysis, including grain size, and by the carbonate content of the beach sediments. It is expected that the local input of terrigenous sediment may affect seagrass meadows and waterways. Continued erosion of the Vrgada cliff could jeopardize anthropogenic infrastructure and alter the island's coastline in the future.
AI and Machine Learning to extend Meteo-Marine Station Observations into the Future
Authors: Azzopardi Joel
Published: February 2025

The real-time availability of data from coastal meteo-marine stations is crucial for various stakeholders, including port authorities, government agencies, researchers, and the general public. While observation data is fundamental, short-term forecasts can significantly enhance planning and decision-making processes. This study explores the application of Machine Learning (ML) techniques to predict hourly values of air temperature, wind speed, atmospheric pressure, and humidity for the next 24 hours. We evaluate three ML models: Long Short-Term Memory Network (LSTM), Random Forest (RF), and Multivariate Linear Regression (LR). The models were trained using Python libraries and Optuna for hyperparameter tuning on datasets of varying lengths from stations in the Malta-Sicily channel. Additionally, we investigated transfer learning with the ERA5 dataset, which provides hourly values over an 83-year period, to address the challenge of limited data availability. The results show that models trained on longer datasets generally achieve better performance. Furthermore, the models demonstrated considerable generalizability, particularly across nearby stations, allowing models trained at one station to be effectively used for predictions at other proximate stations. To support further research and practical application, we have made our models and tools publicly available.
Modeling the high-impact-low-probability oil spills in the Mediterranean
Authors: Liubartseva Svitlana , Coppini Giovanni , Daniel Pierre , Hoxhaj Megi
Published: February 2025

Despite considerable efforts to improve scientific understanding and risk management, governments and businesses remain insufficiently prepared to confront large oil spills considered to be the so called ‘high-impact low-probability’ disasters. To alleviate this problem, we focus on the historical HAVEN oil spill (off the Port of Genoa, 1991) recognized not only as the largest shipwreck in the European waters, but also as one of the worst oil pollution cases in the Med. We reconstruct this spill with the Lagrangian oil spill model MEDSLIK-II forced by the to-date high resolution meteo-oceanographic datasets. Moreover, we run the HAVEN oil spill scenario stochastically sampling virtual spills randomly in space and time. The results are presented as the pollution hazard indices in probabilistic terms, which is supposed to be a representative indicator of future accidents. The highest indices are found in the Alboran Sea, Algerian and Liguro-Provençal subbasins, and in the center of the Ionian Sea. Conversely, the southern part of the Ionian, the areas east of Sardinia and west of Corsica, the Gulf of Lion, the northern Adriatic, and north-eastern Aegean Sea do not reveal high hazards.

Published: February 2025

Marine and coastal data management is crucial for scientific research, economic activities, and environmental monitoring. Marine data is collected from different sources using various tools and methodologies. There are several methods used for formatting marine data, but to put them in a standardized form takes time, effort and knowledge. To overcome the technical difficulties involved in submitting data, a group of 41 international organizations, led by HCMR (Greece) and MARIS (The Netherlands), is active in the EMODnet Data Ingestion project. Their goal is to simplify the process of data acquisition and transformation, ensuring data becomes interoperable and increasing the availability of marine data. By providing a structured platform for the submission, management, and dissemination of marine datasets, the project fosters an environment where data can be easily accessed, shared, and utilized by a wide range of stakeholders, including researchers, policymakers, and public. This paper presents EMODnet Data Ingestion services within the framework of the broader EMODnet. Examples of data sharing and important aspects of the EMODnet Data portal are delivered.
Monitoring the phenomenon of seawater intrusion in the estuary area of the river Magra and in the alluvial plain of the lower Val di Magra (SP)
Authors: Sabattini Marco , Ronchetti Francesco , Arosio Diego , Brozzo Gianpiero , Panzani Andrea
Published: February 2025

Seawater Intrusion (SI) is a critical problem as a consequence of climate change. The progression of the salt wedge inland compromises the quality and quantity of groundwater, seriously damaging agriculture and gradually desertifying the territory. The alluvial aquifer of the Lower Val Magra (LVM) is one of the most important in Liguria (Italy). It supplies drinking water to the city of La Spezia. The main objective of this research is to determine the severity of the SI phenomenon in the LVM aquifer and in the River Magra estuary. Data from different databases (ACAM, Aral, Ispra) and new original data were used for this purpose. The analytical methods focused on multivariate statistics (HAC, PCA and PLS). It was found that the migration pattern of SI along the estuary is mainly controlled by river discharge and wind speed. The weir in Romito (8.5 km from the sea coast) is the current limit of the SI in the R. Magra. About the groundwater, the most salinized wells are concentrated in the Marinella plain. For the other part of the LVM, aquifer water quality is good, but will be deteriorate in the next years as a consequence of climate change.
Towards a Guide for Building Digital Twins of Port Infrastructure
Authors: Tsaimou Christina N. , Tsoukala Vasiliki K.
Published: February 2025

Ports are critical infrastructure assets with a pivotal role in functional and spatial activities associated with maritime transportation. In an era of intense pressures on the digitalization of every part of the economy, building Digital Twins (DTs) of port systems has become increasingly important aiming at solving problems before they occur. Although port DTs are mostly used for logistics and operational purposes, DT technologies can also support lifetime performance management of port infrastructure by investigating the in-service structures’ behavior against potential degradation threats. To this end, the present work conceptualizes a guide for building DTs of port infrastructure based on Structural Health Monitoring (SHM) applications. The guide includes sensors mounted on Unmanned Aerial Vehicles, Geographic Information Systems tools, automation techniques, and structural condition assessments combined to assist in computer-aided twinning. To examine the effectiveness of the guide, a pilot DT was applied for the waterfront facilities of a Greek port, namely Lavrio port. The real-time replicas proved promising in searching for smart maintenance actions.
Adaptation of the coastal protection system at Marina di Pisa, to extreme sea conditions: experimental analysis of the submerged breakwater and gravel beach
Authors: Zannella Amanda , Esposito Andrea , Simonetti Irene , Cappietti Lorenzo
Published: February 2025

The coast of Marina di Pisa has been subjected to strong erosion for decades. The current protective system comprises a large rubble-mound seawall, 6 emerged rubble-mound breakwaters, and 4 cells made up of a submerged breakwater and an artificial gravel beach framed by two groynes at the extremities. One of these cells experiences large amounts of water and gravel overtop onto the promenade and its two main components are studied through three design parameters: gravel nourishment width, gravel nourishment height, and width of the submerged breakwater crest. Fifteen configurations based on the design parameters were experimentally tested under the same wave motion and sea level. Three main outputs were analyzed: gravel overtopping, water overtopping, and final equilibrium profile which included the height and distance from the promenade of the crest formed due to wave action. The results also showed that an optimization between the increase in gravel nourishment width and breakwater width must be found as a large increase in one minimizes the effectiveness of the other. Additional observations on the amount of gravel added and the classification of gravel beaches are also made.
Christoph Pfautz as a Reviewer for the Acta Eruditorum: the Invention of a German Tradition in the Sciences
Authors: Brancato Mattia
Published: February 2025

In 1682, Otto Mencke and Christoph Pfautz founded the Acta Eruditorum, the first fully-fledged German scientific journal. In this paper, I argue that this journal had a fundamental role in shaping the narrative on the rise of the new science in the 17th century, placing Germany as the ideal intermediary between tradition and innovation. In particular, Pfautz’s review of Newton’s Principia in the Acta Eruditorum initiated the Leibniz-Newton controversy, which forced the German tradition to reconsider its role and reshape its philosophical foundations to appeal to a wider international audience.
COMPREENSÃO DA CRIATIVIDADE E DA APRENDIZAGEM EM PROFESSORES DE EDUCAÇÃO FÍSICA
Authors: Rodrigues Natálie dos Reis , Becker Maria Luiza Rheingantz , Mallmann Maria Luiza
Published: February 2025

Conforme a Epistemologia Genética, a aprendizagem está relacionada ao desenvolvimento, ou seja, o desenvolvimento é o processo essencial para a construção do conhecimento pelo sujeito, e cada novo elemento de aprendizagem é uma função de um todo estrutural mais amplo. Enquanto a aprendizagem é provocada por situações, o desenvolvimento é espontâneo. No processo de desenvolvimento da aprendizagem, o sujeito explora ativamente o objeto de conhecimento, podendo criar ou modificar as estruturas internas a partir dessas ações que fazem com que ele conheça o mundo de forma cada vez mais objetiva e diferenciada, por meio da equilibrações majorantes. O objetivo deste artigo é identificar como os professores participantes de pesquisa compreendem os conceitos de criatividade, de aprendizagem e seus desdobramentos. A pesquisa de cunho qualitativo, foi realizada por meio de um estudo de caso integrado e teve como instrumento a entrevista semiestruturada inspirada no Método Clínico de Piaget. Participaram deste estudo 10 professores de Educação Física de escolas de Porto Alegre e Região Metropolitana que aderiram ao Programa Trajetórias Criativas. Os resultados evidenciaram três grupos de resposta baseados nos níveis de tomada de consciência sobre o conceito criatividade. As respostas classificadas no terceiro grupo são as que conseguem explicar os fenômenos estudados de maneira mais aprofundada, referindo aos processos internos cognitivos e afetivos. Quanto ao conceito de criatividade, os professores desse grupo fizeram alusão à construção, à transformação, à interação com o outro, sem citar a necessidade de originalidade. Mas, ao mesmo tempo, ainda com relação à criatividade, pareceram sobrevalorizar os aspectos afetivos relacionados à ludicidade. A criatividade do professor está em focalizar o despertar emoções nos alunos por meio de atividades pedagógicas diferenciadas, que geram interesse e compreensão. Para tanto ele precisa valorizar a participação dos alunos em atividades, debates, pesquisas, sugestões. O conceito de aprendizagem considera a atividade do aluno sobre o objeto de conhecimento como centro do processo de desenvolvimento. Especificamente na disciplina de Educação Física, esses professores citam características estruturais da disciplina que contribuem para aprendizagem do aluno, tais como: o fato de ter uma maior horizontalidade entre professor e aluno e a questão de se trabalhar com o corpo. Conclui-se que os professores do grupo pesquisado compreendem os conceitos de criatividade, aprendizagem e seus desdobramentos de forma que a reflexão sobre a própria prática docente eleva o seu nível de tomada de consciência e a sua compreensão sobre o processo educativo que são condições necessárias para a elaboração de estratégias docentes mais eficazes.

OBJETIVO: Estudiar los axiomas históricos que determinan la evolución de la Constitución y la fundamentación de la teoría. MÉTODO: cualitativo, mediante la dogmática y deóntica jurídica. RESULTADOS: La Constitución, es un texto que organiza políticamente al Estado imponiéndole límites con el respecto de los derechos y libertades. Aunque, Francia e Inglaterra proponen los primeros axiomas de la teoría, Estados Unidos de América consolida y realiza la mejora de ese Estado de Derecho, con la determinación de la teoría de los frenos y contrapesos, permitiendo un difícil equilibrio entre la independencia y autonomía de cada uno de los poderes; así como, la coordinación para hacer posible un gobierno unido y auto controlado. Como aquel sistema panóptico donde la Constitución funciona como vigilante. CONCLUSIÓN: La teoría de la Constitución es la base sólida para el buen funcionamiento de un ordenamiento jurídico dentro de un Estado de derecho; por ende, su estudio establece los criterios para que toda persona pueda comprender los principios que constituyen los pilares de una Constitución para su correcta interpretación. En ese sentido, es determinante que la evolución de su texto es propio de su contexto cultural, social, económico existente en la época que se interpreta; por ende, pueden ser debatidos, pero nunca evadidos, porque sobre esos axiomas se consolida la lucha histórica del valor jurídico de su texto, que si acepta mayor protección, pero, nunca restricción de los mismos Derechos.
