Through the eyes of the viewer : colour, emotion, and genre recognition in movie marketing
Publication . Duarte, Paulo; Pais, Henrique Teles; Filipe, Sara Brito
ABSTRACT: This study investigates how colour influences audience perception in film advertising, particularly through movie posters. Integrating theoretical insights from colour psychology and cultural semiotics, the research addresses a gap in the literature regarding the empirical association between colour palettes, film genres, and emotional responses. Using biometric eye-tracking technology, two experimental within-subjects studies were conducted with 41 participants aged 18 to 40. One study examined colour associations with five film genres (action, animation, romantic comedy, science fiction, and horror), while the other explored emotional responses to monochrome posters based on Plutchik’s wheel of emotions. Results reveal both alignment and divergence from traditional colour-genre conventions, such as the unexpected association of green with sadness and orange with trust, highlighting the role of context and design composition in visual interpretation. Findings also confirm central fixation bias, underscoring the influence of spatial placement on visual attention. The study makes a theoretical contribution to chromatic semiotics in film promotion and offers practical insights for designers and marketers seeking to optimize audience engagement.
The changing landscape of urinary tract infections: Epidemiology, pathogen distribution and antimicrobial resistance over six years
Publication . Lopes, Sara; Coelho, Patricia; Chaves , Catarina; Mateus, Sónia; Metello, João; Rodrigues, Francisco
Background: Urinary tract infections (UTIs) are among the most common bacterial infections worldwide and remain a major cause of antimicrobial prescribing in both Community and hospital settings. Continuous epidemiological surveillance is essential to monitor changes in uropathogen distribution and antimicrobial resistance, particularly in aging populations.
Methods: A retrospective observational study was conducted using urine culture data from a Portuguese tertiary healthcare network between January 2020 and December 2025. Demographic, microbiological, and antimicrobial susceptibility data were extracted from the laboratory information system. After applying predefined exclusion criteria, 44,596 positive urine cultures corresponding to distinct infectious episodes were included. Pathogen distribution, temporal trends, polymicrobial infections and antimicrobial susceptibility patterns were analyzed according to age, sex, and healthcare setting.
Results: During the study period, 165,269 urine samples were processed, yielding 44,596 positive urine cultures. Women accounted for most infections, while individuals aged ≥65 years represented the largest patient group. Of all positive cultures, 41,555 (93.2%) were monomicrobial and 3041 (6.8%) were polymicrobial. Escherichia coli was the predominant uropathogen (49.6%), followed by Klebsiella pneumoniae (17.4%), Proteus mirabilis (7.0%), Enterococcus faecalis (5.3%), and Pseudomonas aeruginosa (5.1%). The overall microbiological profile remained relatively stable throughout the six-year period. Antimicrobial susceptibility testing demonstrated preserved activity of fosfomycin against the principal Enterobacterales, whereas resistance to fluoroquinolones and trimethoprim–sulfamethoxazole remained substantial. Polymicrobial infections occurred predominantly among older and hospitalized patients.
Conclusions: This large-scale six-year surveillance study provides a comprehensive overview of the epidemiology of urinary tract infections within a Portuguese tertiary healthcare network. The findings confirm the continued predominance of Escherichia coli, highlight the growing burden of UTIs among older adults, and emphasize the importance of continuous local microbiological surveillance to support empirical antimicrobial therapy, antimicrobial stewardship, and future public health strategies.
Georreferenciação do Esboço Geomorfológico da Quinta Senhora de Mércules
Publication . Roque, Natália
A compatibilização espacial dos dados sem informação geométrica nativa, executou-se a georreferenciação em ambiente de Sistemas de Informação Geográfica (SIG). O fluxo de trabalho consistiu na importação da imagem, através de rasterização, adquirida com ScanStation (Context HDUltra X,Mod. 4290 de 42”), e na posterior recolha e distribuição homogénea de pontos de controlo geográficos, vinculando feições identificáveis da imagem de origem a coordenadas homólogas da camada de referência. O ajuste espacial foi refinado com base na minimização do erro residual individual e global (RMS Error). O resultado final foi consolidado e exportado como um novo ficheiro matricial georreferenciado, garantindo a integridade métrica necessária para análises espaciais subsequentes.

Industry digitalization technological developments in forest machines towards forestry 4.0
Publication . Sampaio, Carlos; Torres, Pedro; Farinha, Luís
This paper describes a case study, where the applicability of digital tools helps an SME to implement the concepts of Industry Digitization, reinforcing its entrepreneurial activity. We adopted a qualitative research methodology, through a case study, involving a research project for the digitization of the industry and technological developments in forest machines towards forestry 4.0. The case study reveals an example of technological improvements that solve a concrete problem and open the doors of a product to new markets, new customer demands , opening new market horizons through digitally based entrepreneurial practices.
