- Work-family policies and perceived organisational support as drivers of well-being and satisfaction among employees in the tourism industryPublication . Biedma-Ferrer, José María; Medina-Garrido, José Aurelio; Bogren, Maria; RODRIGUES GUITA ALMEIDA, MARIA HELENAThis study investigated the effects of accessible work-family policies (WFP) and organisational support on job satisfaction mediated by employee well-being. Furthermore, it examined whether these relationships differed depending on employees' gender and family responsibilities. The study involved 568 participants employed in the Spanish tourism industry, including front-line workers and managerial staff, with a similar proportion of male and female employees, nearly half of whom had family responsibilities. The valid questionnaires were analyzed using the PLS-SEM technique. The results highlighted the importance of organisational support and the accessibility of WFP in determining satisfaction in the workplace. While WFP accessibility had a residual effect, organisational support had a more substantial impact on overall satisfaction. Moreover, emotional and physical well-being (EWB, PWB) were crucial factors that directly influenced job satisfaction and mediated the relationship. The study revealed that family responsibilities and gender significantly shaped the relationships between organisational support, WFP accessibility, EWB, and PWB.
- Examining the distribution of middle paleolithic nubian cores relative to chert quality in southern (Nejd, Dhofar) and south‐central (Duqm, Al Wusta) OmanPublication . Eren, Metin I.; Bebber, Michelle R.; Singer, David; Pearson, Chloe; Ortiz, Joseph D.; Buchanan, Briggs; Beshkani, Amir; Chlachula, Dominik; Dellmour, Rudolf; Garba, Roman; Marks, Anthony E.; Usyk, Vitaly; Rose, Jeffrey IanLithic raw material properties are often invoked to explain the presence, absence, form, or ontogeny of Paleolithic stone tools. Here, we explore whether the frequency of the Middle Paleolithic Nubian core form and core-reduction systems co-varies with toolstone quality in two neighboring regions in Oman: the southern region of Nejd, Dhofar, and the south-central region of Duqm, Al Wusta. Specifically, we predicted that if raw material differences were influencing the distribution of Nubian cores, the chert would be of higher quality in the southern region, where Nubian cores were frequent, and of lower quality in the south-central region, where they were scarce. We tested this prediction by collecting 124 chert samples from 22 outcrops and then quantitatively assessed two geochemical variables that are widely thought to influence knapping: impurity amount and silica content. We also examined the mineralogical composition, and the crystallite size and lattice strain for quartz (crystalline alpha-SiO2) of representative chert samples. Our results suggest that the cherts in the two regions are similar, which is not consistent with the hypothesis that lithic raw material quality contributed to Nubian core spatial distribution in Oman. We discuss potential alternative hypotheses to explain Nubian core geographic patterning, and provisionally suggest that the scarcity of Nubian cores in south-central Oman may be due to a concomitant scarcity of toolmakers, given a lack of water availability.
- A necrópole da gruta da Verdelha dos Ruivos (Vila Franca de Xira) e a génese do Complexo Campaniforme na região da foz do Tejo (Portugal)Publication . Cardoso, João Luis; Leitão, M.; Ferreira, O. da Veiga; Zbyszewski, G.; North, C. T.; Norton, J.The Verdelha dos Ruivos cave, located around 20 km NNE of Lisbon, is the only necropolis of the Bell Beaker Complex identified in Portugal to date in which it was possible to isolate in a stratigraphic sequence, single burials and reconstruct the original position of the corpses. The cave was occasionally identified in 1973, during the inspection of a Cretaceous limestone quarry, whose exploration front sectioned the cavity, leaving only the distal part of it. The excavation was carried out by a team from the Geological Service of Portugal led by O. da Veiga Ferreira, which included a medicine doctor, which constituted an obvious added value for characterizing the composition of the population and knowledge of the methods of inhumation used. The small crypt that remained of the primitive natural cavity, whose brown filling contrasted with the color of the limestone, was completely emptied by an hardened carbonate breccia, with abundant limestone blocks, containing archaeological remains. The hardness of this very consolidated filling made it difficult to carry out the excavation, which began in October 1973 and ended only in May 1974. Three main levels were identified, consisting of successive individual tombs in dorsal decubitus, on the left or right side, with the body retracted, in the uterine position. It was possible to identify the position of 11 graves, some related with limestone slabs, which constituted the base or covering of the graves. The archaeological remains included all the items considered characteristic of Bell Beaker Complex: sperm whale tooth buttons, gold spirals, a Palmela point, a fragment of a wristguard and ceramics, of which the decorated ones belong exclusively to the Bell Beker Complex, which leads to the conclusion that the funerary use of the cave is exclusively from a community related to this cultural “circle”. The absolute dating carried out allowed us to place the beginning of this necropolis between 2700 and 2600 years BC, extending into the second half of the 3rd millennium BC. These results are consistent with the antiquity of the emergence of the Bell Beaker Complex in the Tagus estuary region, as was demonstrated by the results obtained at the prehistoric settlement of Leceia, located approximately 30 km to the SW, a reality that will be also valued and discussed.
- Estratégias alimentares dos animais domésticos do povoado de Leceia (Oeiras, Portugal) durante a transição do 4.º para o 3.º milénio a.C.: uma abordagem a partir dos isótopos estáveisPublication . Navarrete, Vanessa; Cardoso, João Luis; Dias, Cristina Barrocas; Detry, Cleia; Curto, Ana; Waterman, Anna J.; Wright, Elizabeth; Maurer, Anne‑FranceIn this article, we analyse faunal samples from the Late Neolithic (Layer 4) and Early Chalcolithic (Layer 3) levels of the fortified settlement of Leceia (Oeiras, Portugal) in order to understand the management of the feeding of domestic animals recovered in these excavations. Through the analyses of stable isotopes of δ13C and δ15N in bone collagen, we aim to characterise the grazing systems and the maintenance strategies of the livestock that were consumed and raised in Leceia, in an attempt to obtain a further perspective on the economic complexity of the fortified settlements that emerged during the 3rd millennium in Portuguese Extremadura. The results show the possible use of forage to feed the animals and also seem to indicate the use of fertilised fields. This demonstrates that animal production is already based on intentional practices of animal and land management, as well as on complex exchange networks.
- Estudo petroarqueológico de proveniência de materiais siliciosos de Leceia, Barotas e Monte do Castelo (Oeiras, Portugal)Publication . Jordão, Patrícia; Cardoso, João Luis; João LuísThe aim of this petroarchaeological study was to identify, from a diachronic perspective, between the Late Neolithic and the Middle/Late Chalcolithic, the types of flint used for the manufacture of lithic products in the prehistoric settlement of Leceia, based on the remains found during excavations carried out between 1983 and 2002, and the types of flint observed in the two workshops located in the vicinity of Leceia – Monte do Castelo and Barotas. The construction of a local geological reference of flint has contributed to a more detailed knowledge of the siliceous microfacies of the Bica Formation (Cenomanian) on the Lisbon Peninsula. The correlation of flint samples from archaeological materials with the raw material from potential supply areas, at local and regional level, made it possible to configure a territory of direct supply of flint, collected in local source areas, in primary and secondary formations (alluvium of the Barcarena stream), and also in the form of debitage products produced in Barotas and Monte do Castelo. Leceia would have played a role as an aggregation site, especially from the Early Chalcolithic onwards, with influence on the specialised sites of Barotas and Monte do Castelo, which would have operated in its dependency. In addition to local networks, regional supply networks have been identified, both to the north‑northeast and to the south‑southeast of the peninsula, where finished objects – blades and/or arrowheads – circulated and arrived at Leceia, probably in exchange for local raw materials. Leceia’s involvement in long‑distance exchange networks is confirmed by the presence of exogenous objects, such as oolitic flint blades from Andalusia.
- Contributo para o corpus artefactual metálico do Bronze Final em território português: a pregariaPublication . Melo, Ana Ávila; Cardoso, João LuisIn this article the authors present for the first time two types of nails with long stems from two Late Bronze Age sites in Estremadura, western Portugal. More recently another nail with long stem and a gold conic head was found in a site in southern Portugal of the same age. The rarity of this type of artifacts justified its characterization, which has now been realized.
- Os ouros calcolíticos do povoado pré‑histórico muralhado do Outeiro Redondo (Sesimbra) e da gruta funerária campaniforme da Verdelha dos Ruivos (Vila Franca de Xira)Publication . Cardoso, João Luis; Bottaini, CarloThe paper discusses a group of five gold artifacts originating from Central Portugal, dating back to the latter half of the 3rd millennium BC. One of these artifacts was discovered in the fortified settlement of Outeiro Redondo in Sesimbra, while the remaining four were found in the natural cave of Verdelha dos Ruivos in Vila Franca de Xira which served as a collective burial site associated with the Bell Beaker culture. The study primarily focuses on a typological analysis of the artefacts aimed at comparing these specific gold implements with similar artifacts found elsewhere on the Iberian Peninsula. Additionally, we conducted a non‑invasive analysis using a portable X‑ray fluorescence spectrometer, which determined that they are composed of over 90% gold with varying amounts of silver and copper. Such a composition is consistent with other findings from the same period and geographical region, suggesting a commonality in the sourcing of gold from alluvial deposits along the Tagus River. Overall, the findings contribute to our understanding of metallurgical practices, material culture, and social dynamics during the Chalcolithic in Iberia, particularly within the context of the Bell Beaker phenomenon.

- A influência do olfato no comportamento do consumidor num restaurante de fine dining: o caso check-inPublication . Encarnação, Miguel Baião da; Agapito, Dora Lúcia Miguel; Pereira, Luís Miguel Soares Nobre de Noronha eO marketing sensorial e, em especial o marketing olfativo, tem vindo a tornar-se parte fundamental das estratégias de marketing de muitas empresas. Esta abordagem permite diferenciação e pode impactar o comportamento do consumidor. Apesar de se encontrar bastante literatura ligada ao marketing sensorial, existem muito poucos estudos experimentais realizados em ambiente real na indústria da restauração que se foquem na investigação da aplicação de técnicas de marketing olfativo e a existência de algum efeito no comportamento dos consumidores. O principal objetivo deste estudo é entender se existe uma relação causal entre um estímulo olfativo com aroma a chocolate e a escolha e intenção de compra, por parte dos clientes de um restaurante, da sobremesa com sabor a chocolate. O processo de pesquisa deste trabalho foi elaborado a partir de um desenho experimental clássico, com uma experiência realizada num restaurante de fine dining. O desenho experimental foi formado por um grupo de teste e um grupo de controlo, sendo que o grupo de teste foi exposto a um aroma a chocolate, enquanto o grupo de controlo apenas aos aromas presentes normalmente no restaurante. Este estudo adota uma abordagem quantitativa, tendo a recolha de dados sido realizada através da aplicação de um questionário a uma amostra de 152 clientes do restaurante. Estes dados foram posteriormente analisados através de análises descritivas e testes de hipóteses. Os resultados obtidos apontam para a existência de uma relação causal entre a exposição ao aroma a chocolate e a escolha da sobremesa de chocolate no final da refeição. A escolha da sobremesa de chocolate destacou-se claramente no grupo de teste, quando comparado com o grupo de controlo, onde não foi a primeira opção dos clientes. Apesar dos resultados apontarem que a exposição ao aroma não aumenta o apetite por chocolate, estes demonstram que a presença do estímulo olfativo tem influência direta na escolha da sobremesa de chocolate e na existência de uma sobremesa dominante.
