GPT-4.1 Sets the Standard in Automated Experiment Design Using Novel Python Lib...
Fachada, Nuno; Fernandes, Daniel; Fernandes, Carlos M.; Ferreira-Saraiva, Bruno D.; Matos-Carvalho, João P.Large Language Models (LLMs) have advanced rapidly as tools for automating code generation in scientific research, yet their ability to interpret and use unfamiliar Python APIs for complex computational experiments remains poorly characterized. This study systematically benchmarks a selection of state-of-the-art LLMs in generating functional Python code for two increasingly challenging scenarios: conversational...
Cycles of inequality in the marketplace: insights from macro, marketer, and con...
Thompson, Debora V.; Kirmani, Amna; Hamilton, Rebecca; Li, Andy; du Plessis, Christilene; Fernandes, Daniel; Johnson, Guillaume; McFerran, BrentSeeking inequality via differentiation is a fundamental theme in the marketing literature: consumers derive utility from products that convey socially valued attributes, and marketers target consumers by giving them opportunities to differentiate on socially valued attributes. However, as a large body of evidence shows, inequality can reduce consumer well-being and limit economic growth. In this paper, we take ...
Financial scarcity and cognitive performance: a meta-analysis
Almeida, Filipa de; Scott, Ian J.; Soro, Jerônimo C.; Fernandes, Daniel; Amaral, André R.; Catarino, Mafalda L.; Arêde, André; Ferreira, Mário B.Whereas several studies find that financial scarcity has a detrimental impact on cognitive functioning, some studies find no relationship and others even report beneficial effects. To shed light on this issue we conducted a meta-analysis on the relationship between financial scarcity and cognitive functioning. We went beyond testing the direct relationship between these two concepts and looked at potential mode...

Density separation of petrous bone powders for optimized ancient DNA yields
Fernandes, Daniel; Sirak, Kendra A.; Cheronet, Olivia; Novak, Mario; Brück, Florian; Zelger, Evelyn; Llanos-Lizcano, Alejandro; Wagner, AnnaDensity separation is a process routinely used to segregate minerals, organic matter, and even microplastics, from soils and sediments. Here we apply density separation to archaeological bone powders before DNA extraction to increase endogenous DNA recovery relative to a standard control extraction of the same powders. Using nontoxic heavy liquid solutions, we separated powders from the petrous bones of 10 indi...
A genetic history of continuity and mobility in the Iron Age central Mediterranean
Moots, Hannah M.; Antonio, Margaret; Sawyer, Susanna; Spence, Jeffrey P.; Oberreiter, Victoria; Weiß, Clemens L.; Lucci, MichaelaThe Iron Age was a dynamic period in central Mediterranean history, with the expansion of Greek and Phoenician colonies and the growth of Carthage into the dominant maritime power of the Mediterranean. These events were facilitated by the ease of long-distance travel following major advances in seafaring. We know from the archaeological record that trade goods and materials were moving across great distances in...
Looking up or down on the social ladder: how socioeconomic comparisons shape ju...
Demczuk, Rafael; Mantovani, Danielle; Fernandes, DanielThe increasing inequality rate within countries worldwide makes social comparisons more evident. In seven experiments, we demonstrate that people comparing themselves to others in a superior socioeconomic position (upward comparison) judge that wealthier others should donate more time and money to charity. However, social comparison to others in an inferior position (downward comparison) does not always increas...

Dias, Vanessa; Encarnação, Gisela; Quintino Arias, Yuliet; Fernandes, Daniel; Franco, Filipe; Pinhasi, Ron; Conejo Delgado, Noé; Oliveira, CésarTendo por base vários procedimentos científicos, tais como, a análise antropológica e arqueológica pormenorizada, a leitura do genoma a partir das análises de ADN antigo preservado e a datação pelo método de radiocarbono, a ilustração anatómica do rosto foi ganhando forma, revelando uma mulher entre os 35 e os 45 anos de idade, com cabelos claros e pele ligeiramente morena que, como a cronologia e proximidade s...
The quality of local democracy: an institutional analysis
Sousa, Luis de; da Cruz, Nuno F.; Fernandes, DanielMuch of the literature on quality of democracy is case study-oriented and focused on nation states. Theoretical work and, in particular, comparative empirical research on the quality of local democracy are less advanced. This paper contributes to our understanding of how democracy works from below. It develops a conceptual framing and employs a multidimensional index of the quality of democracy across all 278 m...
Genomes from Verteba cave suggest diversity within the Trypillians in Ukraine
Gelabert, Pere; Schmidt, Ryan W; Fernandes, Daniel; Karsten, Jordan K; Harper, Thomas K; Madden, Gwyn D; Ledogar, Sarah H; Sokhatsky, MykhailoThe transition to agriculture occurred relatively late in Eastern Europe, leading researchers to debate whether it was a gradual, interactive process or a colonisation event. In the forest and forest-steppe regions of Ukraine, farming appeared during the fifth millennium BCE, associated with the Cucuteni-Trypillia cultural complex (CTCC, ~ 5000-3000 BCE). Across Europe, the Neolithisation process was highly var...
