Inteligência artificial e o impacto na gestão da informação
Pereira, Julio; Freitas, Pedro; Teixeira, CatarinaA inteligência artificial (IA) está a revolucionar a gestão da informação, proporcionando novas formas de recolher, analisar e interpretar dados. As tecnologias de IA permitem às organizações automatizar tarefas repetitivas, melhorar a precisão dos dados e obter insights valiosos de grandes volumes de informação. A aplicação da IA na gestão da informação impacta diversas áreas, como a classificação de documento...
Dynamics and spatial variability of Arctic and Subarctic thermokarst lakes and ...
Freitas, PedroThe rapidly thawing permafrost in the Arctic and Subarctic regions poses a complex scientific problem, with its mechanisms defying traditional climate modeling. Unlike gradual thaw, abrupt permafrost thaw processes, such as thermokarst lake and pond formation, depend on intricate local geological and environmental interactions, rendering them extremely challenging to integrate into Earth System Models (ESM). Th...
Diagnosis of Chronic Kidney Disease in Adults in Portugal: Practical Recommenda...
Malheiro, Jorge; Birne, Rita; Biscaia, André; Almeida, Edgar; Nobre, João; Capela, Nuno; Azinheira, Jorge; Nunes Oliveira, Jorge; Lebre, LuísA doença renal crónica representa um problema de saúde pública significativo, afetando cerca de 9,8% da população adulta em Portugal. Pese embora este número, o diagnóstico precoce desta doença nos grupos de alto risco é reduzido. Apesar de serem apenas dois os parâmetros cruciais para o seu diagnóstico – a taxa de filtração glomerular estimada (TFGe) e a albuminúria – em Portugal, mais de 50% dos doentes em es...
Correction to the Article "Diagnosis of Chronic Kidney Disease in Adults in Por...
Malheiro, Jorge; Birne , Rita; Biscaia , André; Almeida , Edgar; Nobre, João; Capela, Nuno; Azinheira, Jorge; Nunes Oliveira, Jorge; Lebre, LuísFollowing publication of the original article, the authors identified an error in the content. The corrected text is presented in the PDF. The original article has also been corrected. Chronic kidney disease represents a significant public health issue, affecting approximately 9.8% of the adult population in Portugal. Despite this figure, early diagnosis of this disease in high-risk groups remains limited. Alth...
What Matters for the Decision to Study Abroad? A Lab-in-the-Field Experiment in...
Batista, Catia; Costa, David M.; Freitas, Pedro; Lima, Gonçalo; Balcão Reis, AnaStudy abroad migration is the fastest growing international migration flow. However, the college completion rates of students from low-income countries are often modest in OECD countries, raising the hypothesis that these migrants are poorly informed about the costs and benefits of their decision. Our work tests this hypothesis by running a lab-in-the-field experiment where graduating high school students in Ca...
Diversity of lakes and ponds in the forest-tundra ecozone: from limnicity to li...
Freitas, Pedro; Vieira, Gonçalo; Martins, Diana; Canário, João; Pina, Pedro; Heim, Birgit; Juhls, Bennet; Couture, Raoul-Marie; Vincent, Warwick F.Arctic and subarctic landscapes have unique hydrological and limnological features and are now experiencing rapid change due to climate warming and permafrost thaw. The highly abundant lakes, ponds, and rivers across these landscapes play an increasingly important role in global biogeochemical cycles and are sentinels of environmental changes. However, studying these remote waters poses challenges for both in s...
Pulmonary arterial hypertension with features of venous involvement: a detectiv...
Cazeiro, Daniel; Plácido, Rui; Azaredo Raposo, Miguel; Brito, Joana; Borba, Alexandra; Guimarães, Tatiana; Pinto, Eugénia; Freitas, PedroPulmonary veno-occlusive disease (PVOD) and pulmonary capillary hemangiomatosis are rare types of histopathological substrates within the spectrum of pulmonary arterial hypertension (PAH) with a very poor prognosis. They are characterized by a widespread fibroproliferative process of the small caliber veins and/or capillaries with sparing of the larger veins, resulting in a pre-capillary pulmonary hypertension ...
A trained Mask R-CNN model over PlanetScope imagery for very-high resolution su...
Freitas, Pedro; Vieira, Gonçalo; Canário, João; Vincent, Warwick F.; Pina, Pedro; Mora, CarlaSmall water bodies (< 0.01 km2) showing diverse limnological properties occur in great abundance across the boreal forest and tundra landscapes of the Arctic and Subarctic. However, their classification, geographical distribution and collective importance for water, heat, nutrient, contaminant and carbon cycles are still poorly constrained. One important step for better understanding the role and evolution of s...
The heterogeneous effects of teacher turnover on student achievement: Evidence ...
Gomes, Sofia; Nunes, Luis Catela; Freitas, PedroThis paper contributes to the literature on the effect of teacher turnover on student achievement. We study an educational system characterized by a centralized teacher allocation model and estimate the causal effects of teacher turnover on students’ exam scores. A small but statistically significant negative effect is found, which is mainly attributed to organizational disruption at the school level and seems ...
