The managerial strategies towards Industry 4.0 were coupled with the emergent normativity on incentive policies to enable automation improvements and industry realignment for new automotive value chains. In other words, the national framework to support company incentives for the concept of Industry 4.0 initiatives has pushed automotive industry managers to establish strategies of new investment on automation and repositioning in the global value chain.
Similarly, the scarcity of available qualifications for Industry 4.0, makes the share of "high road" jobs stable. The qualification process in the automotive industry has increased in parallel with the investment on automation.
An important contribution to this increase on job skills is significantly based on existing vocational training policies, which enable the incoming of higher skilled young job seekers, and a lifelong training and requalification of workers in the automotive sector. We have studied the training offer on “mechatronics” for the automotive sector, including both the manufacturing and repair activities. Data indicates a trend of increase of demand for mechatronic trained technicians with higher skills and preparedness for tasks related to automation, programming, maintenance and production control.
How about compensation? short- and long-term job stability? The young professionals that are seeking for a job in an OEM of the automotive sector, or even in a component provider in this sector, have higher probability and expectations of have better wage income and longer-term job stability due to his specialized skills. We have confirmed these results in our preliminary interviews with vocational training centres and company managers.
The managerial jobs are still privileged in the process realignment of industry, even in those case where the electrification technology tends to replace the ICE one. However, these cases are very limited in Portugal. Only Caetanobus and Mitsubishi-Daimler Fuso are producing electrical vehicles. The other OEMs are in a slower process of technological modernization. The choices over the application of principles of Industry 4.0 concept in their premises implied the recruitment of more jobs with the qualification on mechatronics, and managerial jobs to coordinate and control this technological transformation. In this sense, results do not support the conclusion that these managerial jobs are being eroded.
In parallel, there is an evolution of skills for specialized work clusters (automation, robotics, engine electrification). In our research we verified that the mechatronic trained young professionals are occupying jobs related to automation and robotics. But the skills related to the propulsion technologies based on electrification have a different requirement. Although, mechatronics is mostly related to Industry 4.0 strategy, it is expected that the energy transition will induce changes in the training contents of mechatronic. Some interviews also confirmed this trend. Thus, we can expect the emergence of two work clusters around a) Industry 4.0 competences and b) powertrain electrification.

ABSTRACT Modern birds are typified by the presence of feathers, complex evolutionary innovations that were already widespread in the group of theropod dinosaurs (Maniraptoriformes) that include crown Aves. Squamous or scaly reptilian-like skin is, however, considered the plesiomorphic condition for theropods and dinosaurs more broadly. Here, we review the morphology and distribution of non-feathered integumentary structures in non-avialan theropods, covering squamous skin and naked skin as well as dermal ossifications. The integumentary record of non-averostran theropods is limited to tracks, which ubiquitously show a covering of tiny reticulate scales on the plantar surface of the pes. This is consistent also with younger averostran body fossils, which confirm an arthral arrangement of the digital pads. Among averostrans, squamous skin is confirmed in Ceratosauria (Carnotaurus), Allosauroidea (Allosaurus, Concavenator, Lourinhanosaurus), Compsognathidae (Juravenator), and Tyrannosauroidea (Santanaraptor, Albertosaurus, Daspletosaurus, Gorgosaurus, Tarbosaurus, Tyrannosaurus), whereas dermal ossifications consisting of sagittate and mosaic osteoderms are restricted to Ceratosaurus. Naked, non-scale bearing skin is found in the contentious tetanuran Sciurumimus, ornithomimosaurians (Ornithomimus) and possibly tyrannosauroids (Santanaraptor), and also on the patagia of scansoriopterygids (Ambopteryx, Yi). Scales are surprisingly conservative among non-avialan theropods compared to some dinosaurian groups (e.g. hadrosaurids); however, the limited preservation of tegument on most specimens hinders further interrogation. Scale patterns vary among and/or within body regions in Carnotaurus, Concavenator and Juravenator, and include polarised, snake-like ventral scales on the tail of the latter two genera. Unusual but more uniformly distributed patterning also occurs in Tyrannosaurus, whereas feature scales are present only in Albertosaurus and Carnotaurus. Few theropods currently show compelling evidence for the co-occurrence of scales and feathers (e.g. Juravenator, Sinornithosaurus), although reticulate scales were probably retained on the mani and pedes of many theropods with a heavy plumage. Feathers and filamentous structures appear to have replaced widespread scaly integuments in maniraptorans. Theropod skin, and that of dinosaurs more broadly, remains a virtually untapped area of study and the appropriation of commonly used techniques in other palaeontological fields to the study of skin holds great promise for future insights into the biology, taphonomy and relationships of these extinct animals.

ABSTRACTCrocodylomorph eggs and eggshells are known as old as the Late Jurassic and are frequent components of most multiootaxic eggshell assemblages. Classified within the oofamily Krokolithidae, thei histo- and ultrastructures are conservative throughout geological time, characterised by inverted-trapezoid-shaped shell units that grow from highly spaced basal knobs and present a diagnostic tabular ultrastructure. Here, we report 327 eggshell fragments from a new fossil site from the Maastrichtian of the Southern Pyrenees, Veracruz 1, and erect a new oogenus and oospecies, Pachykrokolithus excavatum oogen. et oosp. nov. characterised by crocodyloid morphotype and a prominent rugosocavate ornamentation. Eggshells from the slightly older locality of Blasi 2b, previously reported as aff. Krokolithidae, are also assigned to this new ootaxon. Different crocodylomorph taxa coexisted during the Late Cretaceous of the Tremp Basin, hindering the attribution of Pachykrokolithus excavatum oogen. et oosp. nov. to a single clade. Nevertheless, allodaposuchid eusuchians were dominant in this ecosystem, and are the most probable producers of Pachykrokolithus excavatum oogen. et oosp. nov. eggs.

O trabalho em plataformas digitais é uma nova forma de trabalho que, em Portugal, não tem ainda definido um modelo regulado de relações de trabalho. Este artigo analisa os perfis de trabalhadores de várias plataformas digitais de trabalho e a sua representação coletiva em Portugal. A diversidade encontrada nos estudos de caso dos perfis dos trabalhadores de cada plataforma explica, em parte, a falta de interesse de movimentos laborais em os representar. O tipo de tarefas e o local de trabalho contribuem para o desinteresse na procura de representantes coletivos, e demonstra os (des)alinhamentos que ocorreram entre trabalhadores e possíveis representantes. Observa-se ainda potencial para outros alinhamentos entre os interesses de diferentes trabalhadores, movimentos sindicais e associações de representação alternativa.

Teachers are central to the choice of tasks proposed to the students. And the teachers’ knowledge is one of the important elements guiding these choices. Despite the different models that conceptualize the teachers’ knowledge to integrate technology in their practices, research has focused essentially on the integration of a single technology. Little is known about how the work with different technologies can contribute to promote the development of the professional knowledge of pre-service teachers (PTs) or how the use of different technologies mobilizes different domains of the PTs’ knowledge. The main goal of this study is to deepen the understanding about the relation between the PTs’ Knowledge for Teaching Mathematics with Technology (KTMT) and their choice of tasks. The study adopts a qualitative and in-terpretative methodology based on one case study. The main conclusions suggest a strong impact of the PTs’ Learning and Teaching Technology Knowledge (a knowledge related to the impact of technology on the teaching and learning process) and a not so strong impact of their Mathematical and Technological Knowledge (a knowledge related to the impact of technology on the mathematical knowledge). The conclusions also point to the potential of the work with different technologies to deepen the PTs reflections and analysis of tasks.
