Title: Caracterização e avaliação do Fenómeno Associado a Lugares Altos na população portuguesa Authors: Diamantino, Margarida Loureiro Resende Reis Abstract: Os objetivos desta investigação foram validar uma breve escala (HPPI) para avaliar o High Place Phenomenon e caracterizá-lo numa amostra de adultos portugueses, composta por 204 adultos da comunidade, com idades compreendidas entre os 18 e os 65 anos, avaliando a sua relação com um conjunto de variáveis sociodemográficas, clínicas e psicológicas relevantes. Verificou-se que os indivíduos com risco suicidário obtiveram resultados significativamente mais elevados no HPPI do que o grupo sem risco. Participou também uma amostra de 60 saltadores de paraquedas, não se tendo verificado diferenças estatisticamente significativas com a amostra comunitária, após o controlo de covariáveis, no modelo da ANCOVA. Através de um modelo de Regressão Linear Múltipla Hierárquica, quatro variáveis sociodemográficas (ser homem, estar desempregado, ter alguma religião, ter diagnóstico de doença psiquiátrica) e três variáveis psicológicas (busca de sensações, comportamentos suicidários e dimensão de evitamento na vinculação) deram um contributo significativo para explicar variância no HPPI; - Characterization and assessment of the High Place Phenomenon in the Portuguese population Abstract: The aims of this research were to validate a short scale (HPPI) to assess the High Place Phenomenon and characterize it in a sample of Portuguese adults, consisting of 204 community adults, aged between 18 and 65 years old, evaluating its relationship with a set of relevant sociodemographic, clinical and psychological variables. It was found that individuals at risk of suicide scored significantly higher on the HPPI than the group without risk. A sample of 60 skydivers also participated, and no statistically significant differences were found compared to the community sample, after controlling for covariates in the ANCOVA model. Using a Hierarchical Multiple Linear Regression model, four sociodemographic variables (being male, being unemployed, having a religion, having a psychiatric disorder diagnosis) and three psychological variables (sensation seeking, suicidal behaviors, and the avoidance dimension in attachment) made a significant contribution to explaining variance in the HPPI.

Title: Comparative study of pozzolanic mortars of the imperial roman period: examples from italy, Portugal, and Greece Authors: Abitbol, Jochanan Abstract: This study offers a comparative archaeometric investigation of pozzolanic mortars from three Imperial Roman contexts — a taberna in Ostia Antica (Italy), Villa Santa Suzana (Portugal) and the Villa of Herodes Atticus close to Doliana (Greece) — aiming to link technological choices to local resources and function inside a structure. A total of nine samples were characterized through complementary methods: macroscopic and stereomicroscopic description, granulometry, X-ray diffraction (XRD) for mineralogy, SEM-EDS for microstructure and elemental composition, Atomic Absorption Spectroscopy and Loss on Ignition for bulk chemistry, ion chromatography for soluble salts, and multivariate statistics (PCA, PERMANOVA, hierarchical clustering, correlation analysis) to synthesise trends. The results demonstrate a consistent technological intention to produce pozzolanic mortars across all sites, though achieved through different material strategies. Analytical data show that Ostian mortars employ natural volcanic pozzolana, whereas those from Villa Santa Suzana and the Villa of Herodes Atticus achieve hydraulic properties through artificial pozzolana, crushed bricks and tiles. Variations in granulometry, porosity, and binder-to-aggregate ratios align with functional roles inside the structures, distinguishing plasters, structural mortars, and pavements. Multivariate statistics reinforce these patterns, revealing standardized practices within each site and marked compositional contrasts between them. These findings illustrate how Roman builders balanced empire-wide technological knowledge with pragmatic adaptations to local resources. These results underscore the interplay between shared Roman technological knowledge and regionally adapted practices. The study highlights the value of multi-method archaeometric approaches for understanding ancient construction technologies and provides a basis for future provenance research and conservation strategies.

Title: Análise dos hábitos alimentares do lobo-ibérico numa área do núcleo populacional Peneda-Gerês: efeitos dos fatores ecológicos e antropogénicos Authors: Oliveira, Beatriz Araújo Abstract: Em Portugal, o lobo-ibérico encontra-se atualmente restrito a zonas montanhosas do centro e norte, devido à degradação do habitat, escassez de presas silvestres e perseguição direta associada a conflitos com atividades humana, nomeadamente à predação do gado. Este estudo analisou os fatores ecológicos, antropogénicos, temporais e individuais que influenciam a dieta do lobo numa área do núcleo populacional Peneda/Gerês. A identificação de pelos e a aplicação de modelos de regressão logística multinomial revelaram uma dieta dominada por ungulados domésticos (66,48%). A densidade de ovinos e as áreas agrícolas estiveram associadas a uma redução significativa na predação da cabra e javali. As restantes variáveis refletiram padrões consistentes com o comportamento oportunista do predador. As comparações entre sexos e alcateias não evidenciaram diferenças significativas, porém foram encontradas variações sazonais. Este estudo contribui para a compreensão da ecologia trófica deste predador e para desenvolver medidas de conservação e mitigação de conflitos; - Analysis oh the feeding habits of the Iberian wolf in an area of the core population Peneda/Gerês: effects of ecological and anthropogenic factors Abstract: In Portugal, the Iberian wolf is currently restricted to mountainous areas in the central and northern regions, due to habitat degradation, scarcity of wild prey, and direct persecution associated with conflicts with human activities, particularly livestock depredation. This study analyzed the ecological, anthropogenic, seasonal, and individual factors influencing wolf diet in an area of the Peneda/Gerês population nucleus. Hair identification and the application of multinomial logistic regression models revealed a diet dominated by domestic ungulates (66.48%). Sheep density and agricultural areas were associated with a significant reduction in the predation of goats and wild boar. The remaining variables reflected patterns consistent with the opportunistic behavior of this predator. Comparisons between sexes and packs showed no significant differences, whereas seasonal variations were detected. This study contributes to a better understanding of the trophic ecology of the Iberian wolf and supports the development of conservation and conflict mitigation measures.
