- Art education: two decades of creation, evaluation and application of an interdisciplinary method of artistic literacyPublication . Leonido, Levi; Pereira, Antonino; Mendes, Liliana; Rodrigues, João Bartolomeu; Morgado, Elsa Maria GabrielThe Interdisciplinary Method of Musical Literacy, Education and Artistic Awareness (MILMESA) is developed and applied essentially in higher education (artistic, cultural and teacher training courses), promoting effective endogenous (interarts) and exogenous interconnection (artistic and other non-artistic areas) of an inter and pluridisciplinary matrix, as well as assuming itself as a privileged vehicle of relationship and extension to the community in the frame of the making of artistic-cultural and pedagogical-didactic events in the European, Luso-Brazilian, Luso-African and Hispanic American territories. It was created, tested and evaluated in five consecutive quadrennia (2002–2023), being regularly adapted, adapted and added to according to the observed realities, evolving into the deepening of new concepts and models of intervention in these domains (e.g., Expressive and Proximal Didactics). Using the ethnographic method and the case study, and having the source of data collection as the document analysis of written and iconographic or visual sources (n = 1386) and participant observation, this study aimed to describe and analyse the application and evolution of MILMESA in terms of education and extension to the community. It was concluded that there was a need to promote, with greater regularity and scope, greater technological interaction via digital platforms and social networks, within the framework of the participation of external specialists (e-DEP) and the very experience of MILMESA’s experiences and initiatives, giving it a more meaningful and participatory range.
- Correlation between suicidal ideation and addiction to various social media platforms in a sample of young adults: the benefits of physical activityPublication . Mendes, Liliana; Leonido, Levi; Morgado, ElsaThe rise in suicide death rates has become a major public health concern, which has led to increased addiction to internet and social media platforms. Despite the limited research available on the relationship between suicidal ideation and addiction to social media such as Instagram and TikTok, this study aims to examine this connection. The study design is cross-sectional, quantitative, comparative, and correlational, with a quasi-experimental approach. The sample includes 315 young adults aged 20 to 30 who were surveyed through the administration of the Suicidal Ideation Questionnaire (SIQ) and the Social Media Disorder Scale-Short Form (SMDS-SF) surveys. The results showed differences in addiction levels based on the type of social media, specifically between TikTok and other social media platforms. The study found that female participants who engage in physical activity (PA) four times a week had lower levels of suicidal ideation than those who did not; there were no differences compared to male participants. This suggests that PA may be a potential strategy for preventing and reducing suicide-related phenomena. The results also indicate that addiction to social media was a statistically significant predictor of suicidal ideation, after controlling for gender and PA.
- Effects of theta-binaural beats auditory stimulation on creativity, psychological well-being and mood states of university students: pilot studyPublication . Mendes, Liliana; Leonido, Levi; Pereira, Antonino; Morgado, Elsa GabrielThis study investigates the impact of theta-frequency binaural beats (BB) on creativity, mood, and psychological well-being in university students, addressing the growing interest and controversy surrounding this auditory stimulation technique. A quantitative, correlational, quasi-experimental design was employed, involving 26 university students aged 18–54 (96.2% female, 3.8% male). Participants listened to theta BB (6-Hz beat frequency on a 250 Hz carrier) for 20 minutes daily using the Binaural Beats App. Instruments included a sociodemographic questionnaire, the reduced Creative Personality Scale (EPC), the short Profile of Mood States Questionnaire (POMS), and the Psychological Well-Being Manifestation Scale (EMMBEP). Results revealed significant improvements in creativity, psychological well-being, and reduced total mood disturbance after exposure to theta BB. Significant differences in total mood disturbance across assessment moments highlighted the intervention's time-sensitive benefits. The study highlights the potential of theta-frequency BB to enhance psychological well-being, mood, and creativity among university students. These findings contribute to the growing body of evidence supporting the utility of BB as a non-invasive tool for improving mental and emotional states. Theta BB may serve as an accessible and cost-effective method for promoting mental health and fostering creativity in educational and therapeutic settings.
- Evaluation of the effectiveness of a quaternary ammonium-based coating in preventing salmonella cross-contaminationPublication . Mendes, Liliana; Barbosa, Joana; Teixeira, PaulaThousands of outbreaks caused by contaminated water or food are reported every year In Europe, it is estimated that in 2019 40 5 of the outbreaks occurred in the home environment[ 1 Domestic kitchens plays an important role in the transfer of foodborne disease causing agents[ 2 since most consumers use contaminated surfaces and equipment in food preparation[ 3 Campylobacter spp Salmonella spp Listeria monocytogenes and Escherichia coli are pathogens that are commonly found on these surfaces, as they are transmitted by food, mainly of animal origin Food contact with these surfaces is a frequent source of cross contamination[ 4 The occurrence of cross contamination is still very common because when cells adhere to kitchen surfaces, they are not easily removed by common cleaning products 5 This difficulty in eliminating pathogens from surfaces in order to prevent contamination, together with the lack of consumer knowledge regarding correct food handling techniques, further increases the risk of cross contamination Household cleaning products have been incorporating antimicrobial agents ( chlorine dioxide, peracetic acid and aldehydes derived from glutamine) in their composition for several decades and have gained the trust of consumers, as they have a great ability to inactivate microorganisms through chemical oxidation However, these cleaning products are only in contact with microbial contaminants on surfaces shortly after application[ 6 One solution to get longer lasting protection is through antimicrobial surface coatings
- Psychometric validation of the Passive and Active Use Measure (PAUM) for Facebook and Instagram among a Portuguese samplePublication . Mendes, Liliana; Leonido, Levi; Pereira, Natércia; Morgado, Elsa GabrielIntroduction. The advent of social media has fundamentally transformed how people interact, bridging the divide between passive digital consumption and active engagement. Objective. This study aims to validate the Passive and Active Use Measure (PAUM) for Facebook and Instagram in a Portuguese sample, exploring distinct interaction modes encompassing Active Social, Active Non-social, Active, and Passive. Methods. Two descriptive, cross-sectional, and quantitative studies were conducted, involving a total of 606 participants (N=198 for study 1, N=408 for study 2), spanning ages 17 to 67. Results. The factor structure of both scales was analyzed, as well as their convergent and discriminant validity and reliability. Both scales–PAUM-Facebook (study 1) and PAUM-Instagram (study 2)–demonstrated robust factorial structures, underscored by sound validity and reliability indicators. Comprising ten and seven items, respectively, these scales are organized into two dimensions: Active and Passive. Conclusion. This study establishes that the PAUM instruments possess strong psychometric properties, rendering them valuable tools for evaluating Facebook and Instagram usage patterns in Portuguese populations, with broader applicability in future research within the field of psychology.
- Social inclusion of transgender people in intercollegiate sports — a scoping reviewPublication . Mendes, Liliana; Morgado, Elsa Gabriel; Leonido, LeviTransgender individuals face discrimination and exclusion in various areas of society, including sports. Notably, intercollegiate athletics suffer criticism for their lack of inclusivity towards transgender athletes. Despite the increasing visibility of transgender individuals and ongoing efforts towards greater inclusivity, there is a significant lack of research on their social integration within college sports. This scoping review aimed to explore the then-current state of research on the social integration of transgender individuals in intercollegiate athletics, identify gaps in the literature, and suggest areas for further investigation. The study examined articles published between 2013 and 2023, using databases such as PubMed, ERIC, and EBSCO Essentials, as well as relevant citations from selected articles. The inclusion criteria for articles were their focus on the social integration of transgender individuals in sports events, publication in English, and relevance to the research question. A standardized technique based on the PRISMA flow diagram 2020 was used to locate, assess, and extract information from eligible research. The results of the study are expected to inform policy and strategy in transgender participation in college sports and promote greater inclusivity for transgender individuals in sports institutions and groups.
