Triassic to Lower Jurassic deposits known as the Silves Group in the Algarve, southern Portugal, have been studied for over 150 years. However, many of this unit’s sedimentological, stratigraphical, and palaeontological aspects remain poorly documented. Here, we present novel observations on sedimentology, stratigraphy, taphonomy, and fauna at the Rocha da Pena site, located in the central part of the Algarve Basin. The investigated sequence is established to correspond to the upper part of the Silves Group. The mudstone, calcrete, and palustrine carbonate facies comprise most of the sequence thickness and are interpreted as having been deposited within coastal alluvial mudflats to palustrine settings under semi-arid and seasonal climates. The overlying siltstone and sandstone facies indicate an environmental shift towards tidally influenced environments, subsequently covered by the latest Triassic to earliest Jurassic volcaniclastics and basaltic lava flows. Furthermore, novel faunal elements, including actinopterygian and unionoid bivalves, are described from mudstone layers. New fossiliferous beds are identified within palustrine facies that yield numerous but poorly preserved materials assigned to cyamodontoid placodonts, hybodont sharks, and actinopterygians. The poor preservation of the remains is attributed to the pedogenetic processes prevalent in the palustrine depositional setting. A distinct faunal composition between the mudstone and palustrine facies is observed. It is preliminarily hypothesized to be likely linked with salinity fluctuations, but sampling bias cannot currently be excluded. The recovered vertebrate fauna aligns most closely with the Carnian and, to a lesser extent, the Norian fossil record. Nonetheless, the precise age of the fossil-bearing levels remains uncertain and can currently be reliably constrained to the upper Carnian–Rhaetian interval. Consequently, this work provides new insights into the palaeoenvironmental evolution of the western Tethys margin during the Late Triassic and highlights the relevance of the Silves Group in reconstructing coastal-continental ecosystem dynamics in southwestern Iberia.Triassic to Lower Jurassic deposits known as the Silves Group in the Algarve, southern Portugal, have been studied for over 150 years.

The integration of digital technology to promote mathematical learning remains challenging for teachers. The continuous difficulty in fully achieving technology’s potential highlights the need to further examine and develop models addressing teachers’ knowledge in relation to technology. In this Research Forum, we analyse existing technology-related knowledge models, exploring similarities and differences. We also consider how these models have been used in research, highlighting tensions driven by emerging technologies, and resulting extensions of the models. Finally, we discuss possible integrations across frameworks and the potential to include dimensions beyond knowledge. This discussion aims to deepen understanding of current models and suggest directions and a research agenda for future development.

Technology integration although highly recommended has proved to be complex. This study aims to characterize the perceptions of secondary mathematics teachers (grades 7th to 12th), from Portugal (Braga region) and Brazil (Campinas region), regarding the teaching of Functions and the use of technology. We also intend to consider the context of the two countries, reflecting on justifications for the differences identified (if any). The study adopts a mixed methodology based on a questionnaire applied to 129 Portuguese teachers in Braga region and 136 Brazilian teachers in Campinas region (quantitative dimension) and on an interview to six Portuguese teachers and six Brazilian teachers (qualitative dimension). The results point to similarities between teachers from Portugal and Brazil, but also to some differences. Technology potential is recognized by teacher from both countries, however teachers from Brazil tend to assume a more traditional use of technology, based on showing and more teacher-centered. This difference can be related to the Portuguese curriculum, valuing a relevant use of technology for more than three decades.

National geoheritage inventories constitute fundamental tools for geoconservation, providing the scientific basis for the identification, assessment, management, and protection of geological heritage. In Portugal, two independent national inventories were developed during the last two decades by the University of Minho (UMinho) and by the Portuguese Geological Survey (LNEG), resulting in partially overlapping databases with different structures and territorial coverage. This paper presents the development of a unified National Inventory of Geological Heritage (NIGH), created through the merging, harmonisation, and expansion of these two previous initiatives. The methodology involved a comparative analysis of both inventories, the development of a relational database, the standardisation of data fields, GIS-based georeferencing, and the implementation of an online dissemination platform within the LNEG GeoPortal. The resulting inventory currently comprises approximately 400 geosites distributed across mainland Portugal and the two Autonomous Regions of the Azores and Madeira, organised into 26 geological frameworks representative of the country’s geodiversity and its geological evolution. The database stores detailed information on geological characteristics, scientific relevance, conservation status, vulnerability, and management requirements, while ensuring ongoing updating through the participation of experts coordinating the different geological frameworks. The NIGH represents the most comprehensive national geoheritage database developed in Portugal to date and provides an essential tool for geoconservation, spatial planning, environmental management, research, education, and geotourism. Remaining challenges include geosite delimitation, legal protection, institutional integration within conservation policies, and the long-term sustainability of the inventory. The NIGH establishes a robust foundation for the future development of proactive geoconservation strategies in Portugal.

Industrial robots are increasingly integrated into manufacturing workspaces, leading to significant changes in work design and altering workers’ framing of work and technology. Even without anthropomorphic design or autonomous features, employees may treat industrial robots as more than mere tools, attributing human-like qualities to them. Yet, prior research typically considers technology either as a tool or as an occasion for altering work relationships between humans, overlooking how relationships with technology itself are crafted. Drawing on 133 interviews across multiple organizations—including robot users, robot producers, and solution providers, we show that mind perceptions (attributions of agency and experience to industrial robots) catalyze relational job crafting with robots. We identify four co-evolving practices—crafting responsibilities, crafting hierarchies, crafting collaboration, and crafting emotional connection—that help workers regain control and regulate daily stress levels, thereby linking relational crafting to both performance and well-being outcomes. Our study extends relational job crafting theory by theorizing mind perceptions as the trigger of human-robot relationality and shifts attention from agentic/anthropomorphic design of technologies to workers’ perceptions of these technologies as core drivers of human-robot-interaction and technology adoption in organizations.
