- Contrast affects stimulus detection in natural scenesPublication . Lopes, Gabriel; Tavares, Mara; Mendonça, CatarinaHow can we predict if a brief stimulus will be detected or perceived when embedded in a dynamic natural scene, such as those we encounter in our daily lives? This is a complex problem, with several approaches to it. Here, we were interested in determining the minimum luminance contrast to the background scene required to achieve detection and shape perception. To investigate this, we used natural videos with briefly appearing natural events, varying in timing of appearance, shape, position, and contrast. We found that there is an interplay between the timing of the event, its position, and the contrast needed for detection. However, for correct shape perception, timing was not a relevant variable. A lower contrast was required for event detection than for correct shape perception. We conclude that contrast alone can affect stimulus detection, but other parameters might interact with it in this task.
- Healthy school, healthy teachers: mediating effect of optimismPublication . Borralho, Liberata; Candeias, Adelinda Araújo; Neves de Jesus, Saúl; Viseu, JoãoIn recent years, the relationship between teachers’ health and organizational health in schools has attracted growing interest in educational research. The studies by Borralho et al. (2020) and Bagdziuniene et al. (2023) indicate that a positive organizational environment—characterized by a supportive climate, effective leadership, and strong interpersonal relationships—has a significant impact on teachers’ physical and mental health, influencing aspects such as professional wellbeing, exhaustion, cognitive disorders, musculoskeletal issues, and voice alterations. Research also highlights that fostering a positive organizational culture through interventions aimed at improving teachers’ well-being can lead to enhanced job satisfaction and resilience, ultimately benefiting both educators and students (Van Woerkom, 2021).
- The origins and spread of the opium poppy ( Papaver somniferum L.) revealed by genomics and seed morphometricsPublication . Machado, Rui; Bonhomme, Vincent; Soteras, Raül; Jeanty, Angele; Bouby, Laurent; Evin, Allowen; Fernandes Martins, Maria João; Gonçalves, Sandra; Antolín, Ferran; Salavert, Aurélie; Oliveira, HugoThe opium poppy (Papaver somniferum L.) is one of the most important plants in human history. It is the main source of opiates used as analgesic medicines or psychotropic drugs, the latter related to addiction problems, illegal trafficking and geopolitical issues. Poppyseed is also used in cooking. The prehistoric origins, domestication and cultivation spread of the opium poppy remain unresolved. Traditionally, Papaver setigerum has been considered the wild ancestor with early cultivation presumed to have occurred in the Western Mediterranean region, where setigerum is autochthonous. Other theories suggest that somniferum may have been introduced by Southwest Asian early farmers as a weed. To investigate these hypotheses, we analysed 190 accessions from 15 Papaver species using genotype-by-sequencing and geometric morphometric (GMM) techniques. Our analysis revealed that setigerum is the only taxa genetically close to somniferum and can be better described as a subspecies. The domesticated plants are, however, distinct from setigerum. Additionally, GMM analysis of seeds also revealed morphological differences between setigerum and somniferum. Some phenotypically wild setigerum accessions exhibited intermediate genetic features, suggesting introgression events. Two major populations were found in somniferum and, to some extent, these correspond to differences in seed form. These two populations may reflect recent attempts to breed varieties rich in opiates, as opposed to varieties used for poppyseed production. This study supports the idea that opium poppy cultivation began in the Western Mediterranean, with setigerum as the wild progenitor, although some wild varieties are likely to be feral forms, which can confound domestication studies.This article is part of the theme issue 'Unravelling domestication: multi-disciplinary perspectives on human and non-human relationships in the past, present and future'.

- The genomics of t’ef and finger millet domestication and spreadPublication . Mekonnen, Degsew; Gomes, Ana; Machado, Rui; Oliveira, HugoThe Northern Highlands of Ethiopia and Eritrea (NHE) were a centre for food production in Africa, hosting one of the earliest agriculture-based complex societies on the continent. The NHE's geographical connections with the Arabian Peninsula, and Nilotic cultures led to the cultivation of southwest Asian crops and African native domesticates in its territory. Additionally, the NHE were also the domestication centre for crops like t'ef (Eragrostis tef (Zucc.) Trotter) and finger millet (Eleusine coracana L. Gaertn L.), after well-adapted local wild plants. Considering the paucity of the archaeobotanical record in the region and food remains' preservation issues, in this study, we aim to investigate the domestication and spread of t'ef and finger millet using genomics and interpreting the results in the light of archaeological proxies. Our data confirmed Eragrostis pilosa and Eleusine coracana subsp. africana as the sole wild progenitors of t'ef and finger millet, respectively. T'ef was initially domesticated in the NHE before spreading into southern Ethiopia and eastwards into southern Arabia. Finger millet spread followed two routes: one leading eastwards through the Red Sea to India, and the other southwards, through Kenya and Uganda, reaching southern Africa.This article is part of the theme issue 'Unravelling domestication: multi-disciplinary perspectives on human and non-human relationships in the past, present and future'.
- Canali, Mauro. The Matteotti murder and Mussolini. The anatomy of a fascist crimePublication . Abreu Colombri, José AntonioMauro Canali’s work is the result of a long cycle of sorting out sources on the fascist system and Mussolini’s political career. Th is editorial project took shape in the months leading up to the centenary of the crime against the multi-talented Giacomo Matteotti through the assembly of various aca demic papers and publications in Italian. From a long list, by thematic spe cialization, the following works stand out: La scoperta dell’Italia. Il fascismo raccontato dai corrispondenti americani, published in Venice (2017), and Il delitto Matteotti, revised and republished in Bologna (2024). Th e diff erent chapters of Th e Matteotti Murder and Mussolini. Th e Anatomy of a Fas cist Crime are grouped into four thematic blocks: “Anatomy of a Policital Crime,” “Mussolini´s Responsabilities,” “Mussolini´s Defenders” and “Af ter.” Th e analytical models focus on the study of public administration doc uments and journalistic publications about a crime that acquired a strong international resonance and shocked large sectors of Italian society.
- The volunteer functions inventory (VFI): adaptation and psychometric properties among a portuguese sample of volunteersPublication . Martins, Cátia; Silva, José Tomás da; Neves de Jesus, Saúl; Ribeiro, Conceição; Estêvão, Maria Dulce da Mota Antunes de Oliveira ; Baptista, Ricardo; Carmo, Cláudia; Brás, Marta; Santos, Rita; Nunes, CristinaThe Volunteer Functions Inventory (VFI) is an instrument widely used to assess volunteers’ motivation based on the Functionalist Model of Omoto and Snyder. It assesses six factors that reflect several motivational functions. The VFI has been translated into various languages and validated in different cultural contexts, but some studies have reported different factor structures (e.g., five or four factors). In the Portuguese context, previous studies have also shown inconsistent results. The aim of this study was to adapt and validate the VFI for Portuguese volunteers, testing several alternative models (nine models) using confirmatory factor analysis. The sample comprised 468 volunteers (76.3% women), aged from 13 to 81 years (M = 36.66, SD = 14.93). The results support the original interrelated six-factor model as the best-fitting one. The VFI showed good internal consistency and convergent validity. Significant correlations were found between the VFI factors, organizational commitment, and volunteers’ satisfaction. Overall, the six-factor VFI is a valid and reliable tool for measuring the motivational functions of Portuguese volunteers, with implications for practice and research in the volunteering field.
- Motivación para el aprendizaje en niños: revisión sistemática de instrumentos de evaluaciónPublication . Ratinho, Elias; dos Santos, Rita Alexandra Mendes; BELÉM MOCHO ALCAPARRA, HELENA SOFIA; Nunes, Cristina; Santos, Andreia; Martins, CátiaGiven the inherent complexity of assessing motivation in educational contexts, the use of theoretically grounded and psychometrically validated instruments is essential to ensure accurate measurement. This systematic review aims to identify and analyze the assessment tools and their psychometric properties used to evaluate learning motivation in children aged 6 to 12 years. Following PRISMA guidelines, searches were conducted in databases such as B-on, ERIC, and PsycINFO, identifying 473 articles published between 2010 and 2024. After applying exclusion criteria, 54 studies were included, revealing 44 distinct instruments based on six predominant theoretical models, Goal Theory. Most instruments demonstrated strong internal consistency, and a wide range of validity indicators-such as criterion, discriminant, and external validity- were frequently reported. The review offers a comprehensive synthesis of validated tools for measuring motivation in elementary education, providing practical guidance for educators and psychologists to enhance motivational assessments in school settings
- Too dense to comprehend—or perfectly packed? the divergent effects of propositional density on levels of text memoryPublication . Harrag, Chaimae; Sabil, Abdelkader; Radvansky, Gabriel A.; Conceição, Manuel CélioPropositional density, a semantic index, calculates the number of idea units within a sentence. While research has shown that propositional density can influence comprehension, its effects on different levels of memory representation, namely, the surface form, textbase, and situation model, remain unexplored. The current study examined how varying levels of propositional density of the context on which target sentences were embedded affected memory at these different levels of representation. A sample of 120 native English speakers read historical texts with either low or high propositional density and then completed recognition tasks targeting each level. Our results indicated that lower propositional density improved memory for the surface form, while higher density enhanced memory for the textbase. Propositional density had no meaningful effect on the situation model level. These findings suggest a complex relationship between propositional density and memory: Higher density appears to impair memory at the surface form level but may create a desirable difficulty to strengthen memory at the textbase level. However, comprehension, as reflected by the situation model level, remains largely unaffected, suggesting that global comprehension relies more on coherence-building and prior knowledge integration than on local semantic density. These findings inform models of discourse processing and have implications for text design, instructional strategies, and cognitive load management in reading comprehension.
- Child-mother relationships and childhood dietary patterns in the Iberian Peninsula uncovered by bayesian isotopic approachesPublication . Toso, Alice; Casimiro, Silvia; Oxborough, Charlotte; Schifano, Simona; García-Collado, Maite I.; Cardoso, Francisca Alves; Soares, Joaquina; Valente, Maria João; Santos, Raquel; Filipe, Vanessa; Gonçalves, Maria José da Silva; Neto, Nuno; Rebelo, Paulo; Silva, Rodrigo Banha da; Filipe, Anabela Novais de Castro; Alexander, MichelleThis study examines trends in infant diet, breastfeeding and weaning in Portugal through time in Roman, Medieval Muslim and Christian skeletal assemblages (1st to the 15th century CE). New stable carbon (delta 13C) and nitrogen (delta 15N) measurements were collected from 143 non-adults and 46 adults that are analysed alongside comparative published datasets from contemporaneous Iberian populations. A statistical package was used to model bone collagen nitrogen isotope data of individuals, quantitatively estimating weaning onset and completion across diverse historical sites. Nutritional intake from infancy to adolescence was reconstructed via Bayesian modelling supported by the OsteoBioR platform using incremental dentine-collagen isotope ratio analysis in six adult individuals. Childhood diets in historical Portugal showed a prolonged weaning time while weaning food included varying degrees of high trophic level protein during both the Roman and Medieval periods. The Bayesian statistical approach offers a comprehensive perspective on child-rearing practices through the lens of diet, including breastfeeding, weaning and nutritional intake during childhood in historical Portugal. The results highlight the variability and complexity of childhood diets over time and between different locations. Overall, the study informs debates about child nutrition practices globally while also offering unique insights into infant nutrition in Iberia over nearly 1500 years.
