Boavida, Nuno, Maria Rosário do Jorge, Marta Candeias, António B. Moniz, and Célia Costa da Cabral A contratação coletiva portuguesa com referências à transição sustentável e justa no setor dos transportes e no setor público. Lisboa: CICS.NOVA, 2024. Abstract

Este relatório pretende fazer uma revisão da literatura sobre a negociação coletiva portuguesa com referências à transição sustentável e justa no setor dos transportes e no setor público.
Portugal tem sido dos países que iniciou já o seu caminho de transição e encerrou as centrais a carvão. Mas em países do Leste europeu, por exemplo, existe muita indústria associada à produção de electricidade a partir do carvão, e onde o encerramento levanta sérias questões sociais. Nestes casos, em particular, é necessário um processo gradual que inclua medidas de apoio à formação e reconversão dos trabalhadores envolvidos.

Burigo, André, and Octávio Mateus. "Allosaurus europaeus (Theropoda: Allosauroidea) Revisited and Taxonomy of the Genus." Diversity. 17.1 (2024): 29. Abstractburigo__mateus_2024_diversity-17-00029.pdfWebsite

Allosaurus is one of the most famous theropod dinosaurs, but the validity and relationships between the different species have been confusing and often questioned. Portugal is relevant to the understanding of the genus in light of the discovery of A. europaeus ML415 from the Early Tithonian of Lourinhã and Allosaurus MNHNUL/AND.001 from Andrés. However, the exact classification and validity of these two specimens has always been controversial. The presence of Allosaurus in Portugal is strong evidence for a North America–Europe Late Jurassic dispersal, later supported by other taxa. A detailed cranial description and specimen-based phylogeny were performed and resolved many of the open questions: (1) The diversity of Allosaurus is limited to three named species: A. fragilis, A. europaeus, and A. jimmadseni. (2) Nine autapomorphies were found in A. europaeus, confirming the validity of the species. (3) Phylogenetic analyses place both Portuguese specimens in the genus Allosaurus, based on the following synapomorphies: jugal bone lateral view, relative heights of quadratojugal prongs, the dorsal prong is equal in height, the jugal bone in lateral view shows shallow accessory pneumatization of the antorbital fossa, the palatine pneumatic recess shape is small, and lacrimal horn morphology has a triangular horn. (4) The Andrés specimen is placed with the A. europaeus and they are considered here to be the same species, which is paleo-geographically and biochronologically congruent. (5) A. europaeus and A. jimmadseni are sister taxa and closer to each other than to A. fragilis. The genus is distributed in occurrences from the United States, Germany, and Portugal, and from the Late Kimmeridgian to the Late Tithonian, while the Cenomanian report from Japan is reidentified as Segnosaurus.

Candeias, Marta, and António B. Moniz. "Artificial Intelligence and Democracy: Portugal." Artificial Intelligence and Democracy. Oslo: EPTA, 2024. 111-117. Abstractepta_report_on_ai_and_democracy_final.pdf

As mentioned in the introduction to this volume, artificial intelligence (AI) functionalities are swiftly becoming integral to knowledge work and digital services. They are, however, also applied in all areas of human work. That is making the public services in Portugal more accessible and efficient. Since mid-90s, with the national strategy towards the Information Society (Missão para a Sociedade da Informação), a wide program for the promotion and development of public digital services have started. In the last decades, and with the definition of this national strategy, successive governments and the national parliament have contributed to stimulate democratic participation, and support decision-making and policy development.

Moniz, António B., and Bettina-Johanna Krings. "Assessing technologies in industrial production: from old to recent controversies." Handbook of Technology Assessment. Ed. Armin Grunwald. London: Edward Elgar, 2024. 151-161. Abstract

This chapter deals with the role of technology in industrial production. Hereby, the enabling character of technology will be strengthened from the perspective of Technology Assessment (TA) in various countries and epochs. Besides the remarkable evolution of technological progress in this sector, the interrelationship of technology with human labor, the creation of specific institutional settings as well as the innovation circles by capital investments must be considered when assessing industrial production. The argumentation line of the article is based on the hypothesis, that the increase of TA studies in the last three decades on industrial production indicates the societal problem orientation of these technological innovations and its impact on employment and job qualification. TA expertise raised awareness of the positive and negative impact of technologies in industry which brings together a variety of options for the decision makers. Furthermore, discourses on ethical values on the future of (industrial) work are highlighted by TA.

Lefint, Jérémy, and António Brandão Moniz. "Assessment of Exoskeletons for Work Activities: The Dilemma behind the Product." Applied Sciences. 14.16 (2024): 7108. AbstractWebsite

The introduction of exoskeletons by many companies has often resulted in potential users not wanting to wear them. Evaluations of the exoskeleton reveal benefits of use, including ergonomic advantages and a reduction of work-related musculoskeletal disorders. How can this contradiction be explained? By searching the available literature, we can identify the methods used to develop these devices and the methods employed to evaluate their acceptance and benefit. By looking at the product from different viewpoints and involving different disciplines, we will get to the root of this discrepancy. Our findings indicate that the product definition, development focus, and evaluation methods do not sufficiently and adequately address the primary goal of exoskeletons. The development of such devices should be prioritized not only for the delivery of support but also for the motivation of the user. Finally, we put forward the proposal to discuss the establishment of a novel development method for the prospective elaboration of exoskeletons.

In this note, we aim to correct some of the results presented in [1]. Namely, the statements of Proposition 2.1, Corollary 2.2, Corollary 2.3, Theorem 2.4 and Theorem 2.6, concerning only the monoids OP_n and POP_n, have to exclude transformations of rank two. All other results of [1], as well as those mentioned above but for the monoids OR_n and POR_n, do not require correction.

de Gomes, Gabriel Jesus, Valter José Guia da Lúcio, and Corneliu Cismasiu. "Development of a high-performance blast energy-absorbing system for building structures." International Journal of Protective Structures. 15.3 (2024): 484-508. AbstractWebsite

Shock absorbers have been widely used in the automotive and aeronautical industries for many years. Inspired on these devices, the paper presents an analytical and numerical assessment of a high performance protective system for building structures against blast loads, which is composed of a shielding element connected to the main structure, at the floor levels, through ductile Energy Absorbing Connectors (EACs). The EACs exploit the external tube inversion mechanism to absorb a significant part of the imparted kinetic energy from the blast wave. While the system prototype has been developed in laboratory, it was characterized and tested in a full-scale blast testing campaign. A validated finite element model was used next to analyze its performance in a more demanding design scenario. The introduction of EACs notably reduces the peak horizontal loads and the kinetic energy transferred to the protected structure, being expected a significant reduction of the stresses in the supporting vertical elements, in addition to the protection of structural and non-structural members. These results encourage further studies of the presented protective system that can be potentially employed for a large variety of blast threat scenarios, especially when increasing the stand-off is not a possible/viable option and sensitive facilities have to be protected.

In this paper, we characterize the monoid of endomorphisms of the semigroup of all monotone full transformations of a finite chain, as well as the monoids of endomorphisms of the semigroup of all monotone partial transformations and of the semigroup of all monotone partial permutations of a finite chain.

Coelho, T., and H. Rocha Forging interdisciplinary paths: Teachers' professional knowledge on disciplinary articulation - Trilhando caminhos interdisciplinares: Conhecimento profissional dos professores sobre a articulação disciplinar. SIEM 2024. Caldas da Rainha: APM, 2024. Abstract2024_siem_coelho_rocha.pdf

The challenges of disciplinary integration in teaching practice, especially in the implementation of tasks that promote interdisciplinary approaches, highlight the importance of teachers' professional knowledge in this process. Using a naturalistic approach, this study aims to characterize the professional knowledge of a physics teacher when adopting an interdisciplinary approach using technology. The results of the research revealed that the teacher mobilizes different types of knowledge, showing a differentiated knowledge of the most appropriate mathematical application to teach a given piece of content, and knowledge of how pedagogical strategies can be aided through different applications using technology.

Rotatori, Filippo Maria, Mattia Quaranta, Filippo Bertozzo, Tom Hübner, Bruno Camilo, Octávio Mateus, and Miguel Moreno-Azanza. "Hadrosaur-like vascularisation in the dentary of an early diverging iguanodontian dinosaur." Historical Biology. 36.10 (2024): 1979-1984. AbstractWebsite

ABSTRACTVirtual palaeontology is a growing field, leading palaeontologists to better understand the microanatomy of many extinct species. The application of techniques such as CT and μCT-scanning allows the researchers to study micro-anatomical features in a non-invasive way and make inferences on the palaeobiology of animals. Dinosaurs have been extensively studied using these techniques, with particular focus on the microanatomy of the cranium, whereas relatively little is known of other cranial elements, such as the lower jaw. Here, we aim to fill this gap, describing the microanatomy of the specimen ML 768, an isolated dentary belonging to a dryosaurid iguanodontian dinosaur from the Upper Jurassic of Lourinhã Fm. The dentary ML 768 was subjected to μCT-scanning, and subsequently the data were segmented in Avizo and rendered in Blender. We identified functional and replacement teeth, recognising remnants of old replacement cycles. Furthermore, we mapped a rich neurovascular network present in the dentary and compared it with reference literature. We found that the high vascularisation is shared with other cerapodan dinosaurs with high tooth replacement rates, although homoeostasis may have also played a role in the development of this condition. Further evidence is needed to appreciate the macroevolutionary significance of these findings.

Carvalho, Fernanda, Ana Nunes, Ana Pagará, Isabel Costeira, Teresa Pereira da Silva, Maria Margarida Rolim Augusto Lima, and João Pedro Veiga. "Historical lime-based flooring mortars from the Church of Santa Maria de Alcobaça monastery (12th century), Portugal: A multi-analytical approach." Archaeometry. n/a (2024). AbstractWebsite

Abstract The Monastery of Alcobaça houses in reserve the ceramic tiles that adorned the floor of the church's apse. These tiles were removed during rehabilitation works and many preserve part of their original fixing mortars. A comprehensive analysis of 21 samples was conducted using a multi-analytical approach (X-ray fluorescence, X-ray diffraction, scanning electron microscopy–energy-dispersive X-ray spectroscopy, μ-Raman spectroscopy, thermogravimetry–differential thermal analysis, optical microscopy, and colorimetry). Results suggest compositional variations in the samples from the back and sides of the ceramic tiles; however, the mineralogy and general characteristics of the aggregates remained consistent between the samples and are coherent with the local geology, suggesting a shared historical origin.

Farham, Babak, Flávio Craveiro, António Brandão Moniz, and Andreas Seebacher Impact of Urban Morphology on Energy Consumption: An Approach Towards Sustainability. Proceedings of the 3rd International Conference on Water Energy Food and Sustainability (ICoWEFS 2023). Cham: Springer Proceedings in Earth and Environmental Sciences, 2024. Abstract

Political and economic crises and issues such as global warming, decreased fossil fuel reserves, environmental pollutions and acid rains are just some of the problems caused by improper energy consumption. Energy efficiency optimization with the right policy and definition of accurate scientific methods proven in energy consumption includes planning, enforcement, organizing permanent control, and continuously reviewing technology upgrades. Additionally, developing legal solutions to implement these programs prevents the destruction and waste of energy resources and reduces the side effects of improper energy consumption. The shape of the city and its components can affect the city’s quality and its spaces, as well as the air quality change, creating a particular climate in their area, causing phenomena such as heat islands, dust, rain, albedo, atmospheric inversion, and some others. By making changes in the shape of the city, both on a large scale and a micro-scale, atmospheric currents and, consequently, air quality in cities can be improved. Urban morphological indicators, including building height, building type, occupancy level, segmentation, block size, block shape, density, and urban green, can affect the weather and climate conditions outside and inside the building and, thus, the energy demand in the areas. By creating effective reforms in the model of configuration of the urban regions, including the pattern of land fragmentation, the physical characteristics of buildings, the network of passages and open spaces, it is possible to increase the energy efficiency of buildings in the long term in the regional(synoptic) climatic conditions of the city and the neighbourhood.
