- The moderating effect of health orientation and subjective norms on the relationship between personal values and organic food purchase intentionPublication . Oliveira, Alessandro Silva de; Campos, Rita de Cássia Leal; Quiroga Souki, Gustavo; Boas, Luiz Henrique de Barros VilasUnderstanding how organic food consumers' (OFCs) values influence their organic food purchase intention (OFPI) is paramount. This study examines the impact of OFCs ' values on OFPI and the moderating role of health orientation and subjective norms in this relationship. This study involved 307 OFCs who filled out an online form regarding attributes, consequences, and values (A-C-V), OFPI, health orientation, and subjective norms related to organic food consumption. Using PLS-SEM and the Means-End Chain Theory, results indicate that OFCs' values positively influence OFPI. Health orientation positively moderates the relationship between values and OFPI, while subjective norms negatively moderate it.
- Cognitive, affective and behavioural repercussions of perceived quality in tourism vocational education: insights from self-determination theoryPublication . Silva, Rejane Santana da; Quiroga Souki, Gustavo; Oliveira, Alessandro Silva de; Vieira, Luís Sérgio; Dionísio Serra, Manuel AntónioPurpose – 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.
- Does guests-perceived value for money affect WOM and eWOM? The impact of consumer engagement on SNS on eWOMPublication . Quiroga Souki, Gustavo; Oliveira, Alessandro Silva de; Barcelos, Marco Túlio Correa; Martins Guerreiro, Maria Manuela; da Costa Mendes, Júlio; Moura, Luiz Rodrigo CunhaPurpose – Hotels provide high-quality guest experiences to generate perceived value for money (PVM), positively influencing word-of-mouth (WOM) and electronic word-of-mouth (eWOM) communication. This study aims to (1) verify the impacts of the perceived quality by the guests about their experiences in hotels on their PVM; (2) inspect the influence of guests’ perception of hotel prices on PVM; (3) examine the impacts of guest PVM on their hotel experiences on WOM and eWOM and (4) investigate the consequences of the hotel guests’ behavioural engagement on social networking sites (HGBE-SNS) on eWOM. Design/methodology/approach – This quantitative and descriptive study consists of a survey with 371 guests who evaluated their experiences at three hotels in Brazil. PLS-SEM tested the hypothetical model that resorted to the stimulus-organism-response theory (S-O-R), proposed by Mehrabian and Russell (1974). Cluster Analysis compared the PVM, WOM and eWOM of groups of hotel guests with different levels of social media engagement. Findings – Perceived quality by hotel guests positively impacts PVM. Perceived price negatively influences PVM. PVM had a positive and robust impact on WOM. PVM impacts and explains weakly eWOM. In contrast, HGBE-SNS affects and better explains eWOM than PVM. Originality/value – This unprecedented investigation concomitantly exhibits the relationships between perceived quality, price, PVM, WOM, eWOM and HGBE-SNS. Hotels must offer high perceived quality experiences to influence PVM and WOM positively. PVM is unable to stimulate eWOM strongly. HGBE-SNS is pivotal for guests to share their hotel experiences through eWOM. This study suggests marketing strategies for hospitality companies to amplify customer engagement on SNS.
- Organic food-buying intention drivers: a study based on means-end chain theoryPublication . Oliveira, Alessandro Silva de; Quiroga Souki, Gustavo; Boas, Luiz Henrique de Barros VilasPurpose – Understanding how attributes, consequences and values (A-C-V) influence the predisposition to purchase and buying intention of organic food consumers (OFC) is crucial for its stakeholders. This study aims to (1) investigate whether OFC perceptions of the A-C-V impact their predisposition to purchase and buying intention; (2) examine the mediating effect of predisposition to purchase on the relationship between OFC personal values and their buying intentions and (3) verify whether consumers with distinct levels of organic food-buying intention perceive differently of the A-C-V, predisposition to purchase and consumption frequency. Design/methodology/approach – This quantitative study comprised 307 consumers who filled out a form about their perceptions of organic foods’ A-C-V and their consumption frequency, purchasing predisposition and buying intention. Partial least squares strutural equation modelling (PLS-SEM) tested the hypotheticalmodel that resorted to themeans-end chain (MEC) theory (Gutman, 1982). Cluster analysis based on OFC’s buying intentions compared their perceptions of the A-C-V, purchasing predisposition and consumption frequency. Findings – The OFC’s perception of the attributes of these foods impacts the consequences of their consumption and values. Such values positively influence their purchase predisposition and buying intention. Predisposition to purchase measured the relationship between OFC values and purchase intention. Three OFC clusters were identified according to their buying intentions. Such groups perceive the A-C-V singularly and have different purchasing predispositions and consumption frequencies. Originality/value – OFC values directly influence buying intentions. However, the predisposition to purchase strongly mediates the relationship between values and buying intentions, producing an indirect impact more notable than a direct one. It brings academic and managerial contributions to organic food stakeholders.
