  • Cognitive, affective and behavioural repercussions of perceived quality in tourism vocational education: insights from self-determination theory
    Publication . Silva, Rejane Santana da; Souki, Gustavo; Oliveira, Alessandro Silva de; Vieira, Luís Sérgio; Dionísio Serra, Manuel António
    Purpose This study aimed to investigate the influence of the perceived quality by students regarding their experiences in vocational schools in tourism, hospitality and food service on cognitive and affective responses (satisfaction, self-efficacy expectations and self-regulation strategies of motivation for learning - SRSML) and commitment (behavioural response). Design/methodology/approach A cross-sectional survey was conducted with 454 students from twelve Turismo de Portugal IP-affiliated schools. The theoretical framework was rooted in Self-Determination Theory (SDT) and PLS-SEM, using ADANCO 2.3 software to test the proposed model. Findings Perceived quality by students concerning their school experiences are socio-contextual factors that directly influence their satisfaction and self-efficacy expectations (cognitive and affective responses). Satisfaction and self-efficacy expectations positively affected SRSML. Finally, satisfaction and the SRSML positively impacted the students` commitment to schools (behavioural response). Originality/value This study contributes to academia by comprehensively addressing 16 perceived quality dimensions within vocational education. It aligns with SDT, revealing that socio-contextual factors affect students’ cognitive, affective, and behavioural responses. Additionally, it demonstrates positive relationships between student satisfaction, self-efficacy expectations, SRSML, and students’ commitment to vocational education institutions. This study emphasises the multidimensional nature of perceived quality, urging educational institutions to address tangible and intangible dimensions to develop strategies to provide high-quality experiences, increasing students` satisfaction, self-efficacy expectations, motivation, and commitment.
  • Mediterranean Diet gastronomic experiences using olive oil and goat cheese
    Publication . Ratao, Isabel; Nunes Cabrita, Patrícia; Silva, Beatriz; Viegas, Carina; Dionísio Serra, Manuel António; Quintas, Célia
    The present study aims to develop three food formulations, spreadable olive oil, goat cream cheese, and a cold dessert made of carob and goat cheese, using local elements of the Mediterranean diet (MD), namely, olive oil, fresh goat cheese, and carob derivatives in addition to hydrocolloids. The final products, with the best spread- ability, texture and consistency, were obtained using: a) methylcellulose 6% (w/v) for the spreadable olive oil; b) Locust Bean Gum (LBG) (0.5% w/w) for goat cream cheese; and c) Goat cream cheese (43.4%), carob flour (8.7%), glucose syrup (26.1%), olive oil (14.6%), powdered goat milk (3.8%), chia seeds (0.5%), LBG (0.7%), and cinnamon for the cold dessert. Subsequently, foods were refrigerated until evaluated by a consumer panel of 101 untrained tasters aged between 15 and 49 years. All the attributes were assessed on a scale from 1 to 5. The products were well accepted by the tasters with no significant differences registered among the different age groups regarding the food attributes, except for the sweetness of the dessert. The goat cream cheese obtained the highest acceptability (4.09 f 1.16-3.88 f 0.86) and creaminess (4.22 f 0.80-4.33 f 0.65) among the youngest consumers (<30 years), while the acceptability of spreadable olive oil was evaluated with values of 3.24 f 1.33-3.17 f 1.14 by the same age group, indicating the need to add seasonings, as salt substitutes, to improve the attributes flavour and aroma. The results highlight the potential of the three formulations to expand the range of food products and processing strategies in the hospitality, catering, and food industry, as well as to provide alternative foods associated with the MD food pattern.
