This study aims to verify, through the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2), the factors involved in the process of adoption and intention to use the Airbnb platform by Brazilian users. This study, which is characterized as a quantitative research study of the survey type, was applied to 263 individuals who knew the platform; for the data analysis, Partial Least Squares Structural Equation Modeling (PLS-SEM) was used. The results show that the constructs: Performance Expectancy, Effort Expectancy, Social Influence and Habit, have an impact on the intentions of individuals. By highlighting these factors, this study contributes to the identification of consumer motivation and the expansion of Airbnb in Brazil. It also extends the use of the UTAUT2 model to the context of shared economy. RESUMO:A multiplicação de modelos de hospedagem compartilhada no turismo e o crescimento da plataforma Airbnb têm impactado a indústria de turismo. O objetivo desse artigo foi verificar, por meio do Modelo de Aceitação de Tecnologia Estendido (UTAUT2), os fatores envolvidos no processo de adoção e intenção de uso da plataforma Airbnb pelos usuários brasileiros. Caracteriza-se como uma pesquisa quantitativa do tipo survey, aplicada a 263 indivíduos que conheciam a plataforma. Como técnica de análise, utilizou-se a Modelagem de Equações Estruturais de Mínimos Quadrados Parciais (PLS-SEM). Os resultados apontam que os construtos expectativa de desempenho, expectativa de esforço, influência social e hábito, têm impacto sob a intenção de uso dos indivíduos. Ao ressaltar tais fatores, o estudo contribui para a identificação da motivação dos consumidores e da expansão do Airbnb no Brasil. Além disso, amplia o uso do modelo UTAUT2 para o contexto da economia compartilhada. PALAVRAS-CHAVE:Hospedagem compartilhada, Airbnb, UTAUT2.

Objectives: investigate the association between breastfeeding duration and the incidence of severe caries in preschoolers. Methods: a cohort study was conducted with 132 pairs of mothers and children in the city of Diamantina, Brazil. Data collection was performed in 2 moments: when the children were between two and three years of age (baseline- 2013/2014) and after three years (T1-2016/2017). In both moments, children were evaluated for dental caries (International Caries Detection and Assessment System - ICDAS) and a questionnaire was administered to the mothers addressing socioeconomic aspects and thee habits of children. The outcome evaluated was the incidence of severe caries (Dentin caries - ICDAS Codes 5 and 6). Data analysis involved descriptive statistics, chi-squared test and Poisson hierarchical regression with robust variance. Results: children who breastfed for more than 24 months (RR = 2.24 CI95%= 1.23-4.08), those whose parents were separated (RR = 1.73 CI95%= 1.11-2.69), and those with estab-lished/severe caries (RR = 2.74 CI95%= 1.37-5.49) at baseline were at greater risk of incidence of severe caries after three years. Conclusion: breastfeeding for more than 24 months is a risk factor for incidence of severe caries. In addition, family structure and established or severe baseline caries were associated.

Resumo Normas sociais de papel de gênero influenciam comportamentos e afirmam identidades e pertencimento a determinados grupos. Mesmo que alterem-se conforme padrões éticos, sociais e culturais, vão existir normativas dominantes. Este estudo validou para a realidade brasileira o Inventário de Conformidade com Normas Masculinas (CMNI-29) e buscou indícios da sua aplicabilidade a fatores específicos do consumo de bebidas alcoólicas de jovens universitários. Foram coletados dados de 341 homens, entre 19 e 25 anos, residentes em Minas Gerais e São Paulo. Os participantes completaram o CMNI-29 e perguntas sobre seu consumo de álcool. Mesmo com as adaptações realizadas para a adequação ao contexto, o inventário foi considerado válido. De maneira geral, os dados de confiabilidade se mostraram satisfatórios e atingiu-se validade convergente e discriminante para todas as dimensões da masculinidade. O CMNI-29 mostrou-se uma medida útil para compreender as múltiplas dimensões da masculinidade no comportamento. Além disso, indícios de influência das normas sobre a frequência de consumo de álcool foram encontrados. O uso da escala amplia o escopo de pesquisa de gênero no país, e possibilita a busca de seu efeito com outras variáveis e comportamentos de saúde que atingem esta população.

Purpose This study aims to understand the extent to which packaging influences Brazilian parents' purchasing willingness based on children's food preferences for unhealthy food products. Design/methodology/approach Parents, with children up to 12 years old, answered questions about the positive influence of the packaging on the children, the preferences of the children in their willingness to buy and the propensity to give in to the desires of the children. Data analysis was performed with the statistical software SPSS and Stata used for structural equations modeling. Findings The results back the outlined hypotheses and point out that the characteristics of the packaging positively influence children's preferences as well as parents’ who are prone to give in to such influences. In some relationships, there was a minute moderating effect of social desirability and social class. Research limitations/implications The research presents as a limitation the nature of the sample, parents, to the extent that the influences of the packages on the children were analyzed from their perspectives. Practical implications Findings from the research can be used to think about preventive public policies to protect children as highly vulnerable subjects. Another practical implication is that the same marketing strategies that are used for unhealthy foods can also be used for healthy foods, improving their linkage to the children once there are evidences that packaging can positively influence their preferences. Originality/value The originality of this study is to focus on children's food preferences for unhealthy products and in parents with children up to 12 years old, which is not often investigated by researchers.
