Volunteering for a Lifetime? Volunteers’ Intention to Stay in Portuguese Hospitals

The current study aims to study Hospital volunteers’ intention to stay in an organization through understanding motivation, management factors, and satisfaction. A total of 304 Hospital volunteers, mainly women, completed a questionnaire measuring motivations, management factors, satisfaction, and intention to stay. In this study, structural equation modeling was used. Results demonstrate that there is a positive relationship between (a) motivation and satisfaction, (b) management factors and satisfaction, (c) satisfaction and intention to stay, and (d) motivation and management factors. These results present important outcomes that should be reflected in the way organizations operate. This research indicates aspects which are most valued by volunteers and allows NPOs to design and establish appropriate and assertive management policies.

Marketing experiencial, emoções, satisfação e lealdade

O marketing transacional apresenta-se nos dias de hoje insuficiente para fazer face às exigências de um consumidor mais participativo, seletivo e crítico. No mercado global, industrializado e em constante evolução tecnológica, é, cada vez mais, difícil obter um grau de diferenciação assente apenas nos benefícios funcionais e racionais. O marketing transacional evoluiu para o marketing relacional, constituindo o cliente o centro do processo de trocas. A economia das experiências alterou a forma como as marcas trabalham o mercado, introduzindo o conceito de experiências, o que por sua vez conceptualizou o marketing experiencial, orientado para a gestão da experiência do cliente, transformando o ato de consumo em algo memorável, cheio de estímulos sensoriais e emocionais, convertendo-se, por vezes, no próprio produto, seja ele de âmbito industrial, desportivo ou mesmo cultural. Este grau de envolvimento do cliente com a marca é elemento gerador de emoção, de satisfação, de lealdade e de valor. Este trabalho pretendeu analisar a importância e os componentes estimuladores do marketing experiencial e a sua relação com as emoções, satisfação e a lealdade dos consumidores no evento cultural “Serralves em festa 2013”. Para tal, utilizamos uma metodologia de investigação quantitativa, com recurso a análise de equações estruturais, suportada por uma pesquisa teórica. O estudo empírico realizado, baseado num inquérito por questionário, possibilitou obter uma amostra de 264 respostas válidas. Após a validação e melhoria das escalas de medida dos conceitos, os resultados destas e do modelo estrutural demonstraram valores adequados. Estudaram-se e comprovaram-se as relações previstas nas hipóteses, nomeadamente, a relação positiva do impacto das experiências no comportamento do consumidor, designadamente, na sua emoção e satisfação e o impacto destas na sua lealdade. Entre as variáveis estudadas foram obtidos interessantes níveis de correlação e capacidades preditivas.

Análise das determinantes da e-lealdade no comércio eletrónico

Objetivo – O objetivo deste trabalho é analisar e medir os determinantes da e-lealdade de um cliente no comércio eletrónico em Portugal. Metodologia – Foi realizado um estudo quantitativo empírico confirmatório e explicativo, a partir da identificação de um modelo teórico, suportado pelo levantamento bibliográfico sobre variáveis latentes, suscetível de investigar as relações entre os determinantes da e-lealdade. Os dados foram recolhidos através de um instrumento de medida, disponível online, o qual, permitiu obter uma amostra válida de 394 respondentes. As hipóteses foram testadas através de um modelo de equações estruturais. Resultados e conclusões – Estudaram-se e comprovaram-se a maioria das relações previstas e hipóteses, nomeadamente, a relação positiva das várias dimensões da e-confiança, e-satisfação e da e-qualidade de serviço na e-lealdade. A e-satisfação e a e-qualidade de serviço apresentam, também, um contributo interessante para a e-confiança que os consumidores têm nos produtos/serviços online. Quanto à e-satisfação dos consumidores foi possível verificar que a mesma apresenta uma variação, de acordo com a e-qualidade de serviço e a e-confiança, por parte dos consumidores online. Foi cumprida a validade convergente e discriminante das escalas de medida e a boa qualidade psicométrica das variáveis. Estas evidenciaram bons níveis de correlação e capacidades preditivas. Limitações/implicações – Os resultados obtidos precisam ser analisados com toda a precaução, não podendo ser objeto de generalizações, face ao uso de uma amostra de conveniência. O facto de os inquiridos avaliarem um website que estão já familiarizados pode constituir uma outra limitação. A ausência de estudos nacionais homólogos teve algumas implicações na discussão dos resultados. Originalidade/valor – O principal contributo deste estudo é constituir o primeiro realizado em Portugal, à data, onde se investigou e estimou um modelo proposto sobre os determinantes e antecedentes da e-lealdade no comércio eletrónico.

Impact of oral health on health-related quality of life : A cross-sectional study

Background: Despite the consensus regarding the existence of a relationship between “impacts on oral health” and “health-related quality of life”, this relationship, considering the latent nature of these variables, is still poorly investigated. Thus, we performed this study in order to determine the magnitude of the impacts of oral health, demographic and symptom/clinical variables on the health-related quality of life in a Brazilian sample of dental patients. Methods: A total of 1,007 adult subjects enrolled in the School of Dentistry of São Paulo State University (UNESP) - Araraquara Campus for dentistry care between September/2012 and April/2013, participated. 72.4 % were female. The mean age was 45.7 (SD = 12.5) years. The Oral Health Impact Profile (OHIP-14) and the Short Form Health Survey (SF-36) were used. The demographic and symptom/clinical variables collected were gender, age, economic status, presence of pain and chronic disease. The impact of studied variables on health-related quality of life were evaluated with a structural equation model, considering the factor “Health” as the central construct. The fit of the model was first analyzed by the evaluation of the goodness of fit indices (χ 2 /df ≤ 2.0, CFI and TLI ≥ 0.90 and RMSEA < 0.10) and the evaluation of the variables’ impact over health-related quality of life was based on the statistical significance of causal paths (β), evaluated by z tests, for a significance level of 5 %. Results: We observed adequate fit of the model to the data (χ 2 /df = 3.55; CFI = 0.95; TLI = 0.94; RMSEA = 0.05). The impacts on oral health explained 28.0 % of the variability of the health-related quality of life construct, while the total variance explained of the model was 39.0 %. For the demographic and symptom/clinical variables, only age, presence of pain and chronic disease showed significant impacts (p < 0.05). Conclusion: The oral health, age, presence of pain and chronic disease of individuals had significant influence on health-related quality of life.

Family relationship and parenting practices: a pathway to adolesents’ collectivist and individualist values?

Adolescents’ perceptions of parenting and family relationships are important variables for identifying mechanisms involved in how children acquire values and how these values are transmitted through families. In a sample of 515 adolescents, we investigated whether perceptions of the quality of parental practices would predict adolescents’ collectivist and individualist values. We hypothesized that perceived quality of family relations would mediate the relationship between the quality of parental practices and collectivist values but not of individualist values. The results of structural equation modeling suggested that perception of the quality of parental practices predicted adolescents’ both collectivist and individualist values. The predicted mediation effect was found for collectivist values, but not for individualist values. The results point to different functions of parenting and family relations on value acquisition. Implications for practice, such as the development and implementation of interventions to improve the formation of adolescents’ values by enhancing the quality of parenting and family relationships are discussed.

Adolescent parents’ values: the role played by retrospective perceptions of the family-of-origin

Family-of-origin is an important system in individual’s lives, and its influence is extensive over the life cycle. The aim of this study was to investigate, in a sample of adolescents’ parents, whether their retrospective perceptions of parenting and relationship qualities within their families-of-origin during adolescence predicted their current collectivist and individualist values. Participants included 110 Portuguese adults with a mean age of 46.86 years old. The results of structural equation modeling supported that retrospective perceptions of parenting and relationship qualities in the family-of-origin predicted the adults’ collectivist values but not their individualist values. This study highlights the importance of retrospective perceptions of supporting and non-rejecting parenting for value acquisition. The results also suggest that values that preserve and protect family connections and collaborations are more likely to be socialized by families. Implications for practice and for the theories on parenting, values, family-of-origin influences and family intergenerational transmission are discussed.

Desenvolvimento de talentos no desporto : aspectos psicológicos

A presente investigação tem como principal objetivo compreender a relevância de diversos fatores sociodemográficos e psicossociais inerentes ao desenvolvimento do talento em contexto desportivo, numa perspectiva multidimensional. Procedeu-se a uma avaliação quantitativa de jogadores de futebol, integrados num clube de elite, com idades compreendidas entre os 13 e os 19 anos. No sentido de avaliar os construtos psicológicos considerados no presente estudo (motivação, perfecionismo, suporte parental, resiliencia, coping e compromisso) foram utilizados os seguintes questionários: Sport Motivation Scale - SMS (Pelletier et al., 1995); Multidimensional Perfectionism Scale – MPS (Frost, Marten, Lahart, & Rosenblate, 1990); Own Memories of Parental Rearing – EMBU (Perris, Jacobson, Lindstörm, Von Knorring, & Perris, 1980); Resilience Scale – RS (Wagnild & Young, 1993); Athletic Coping Skills – ACSI 28 (Smith, Schutz, Smoll, & Ptacek, 1995); e Elite Athlete Commitment Scale – EACS (Ramadas, Serpa, Rosado, Gouveia & Maroco, 2013). A significância da variável nível de prestação (elite/sub-elite; dispensados/retidos) sobre os diversos constructos psicológicos foi avaliada através da análise da covariância multivariada (MANCOVA), da análise de equações estruturais (CBSEM) e da técnica de míninos quadrados parciais (PLS). Os jogadores mais bem sucedidos (jogadores de elite e jogadores retidos) percecionaram maior suporte parental, demonstraram níveis mais elevados de compromisso, resiliência, autodeterminação, capacidade de adaptação e confronto, assim como um perfeccionismo ajustado. No que concerne às variáveis sociodemográficas, constatou-se que os jogadores retidos jogam predominantemente no segundo ano do respetivo grupo de idade e têm uma idade inferior aos jogadores dispensados. Os resultados obtidos poderão constituir um relevante suporte para futuros programas educacionais que incidam sobre temáticas relacionadas com os compromissos necessários à prossecução e manutenção de níveis de elite, estratégias de coping, gestão da rotina diária, e o papel dos pais no processo de formação do jovem desportista.

Entrepreneurial intention, cognitive social capital and culture: empirical anaylisis for Spain and Taiwan

The main purpose of this paper is building a research model to integrate the socioeconomic concept of social capital within intentional models of new firm creation. Nevertheless, some researchers have found cultural differences between countries and regions to have an effect on economic development. Therefore, a second objective of this study is exploring whether those cultural differences affect entrepreneurial cognitions. Research design and methodology: Two samples of last year university students from Spain and Taiwan are studied through an Entrepreneurial Intention Questionnaire (EIQ). Structural equation models (Partial Least Squares) are used to test the hypotheses. The possible existence of differences between both sub-samples is also empirically explored through a multigroup analysis. Main outcomes and results: The proposed model explains 54.5% of the variance in entrepreneurial intention. Besides, there are some significant differences between both subsamples that could be attributed to cultural diversity. Conclusions: This paper has shown the relevance of cognitive social capital in shaping individuals’ entrepreneurial intentions across different countries. Furthermore, it suggests that national culture could be shaping entrepreneurial perceptions, but not cognitive social capital. Therefore, both cognitive social capital and culture (made up essentially of values and beliefs), may act together to reinforce the entrepreneurial intention.

Poor and Sick: Estimating the relationship between Household Income and Health

This study evaluates the effect of the individual‘s household income on their health at the later stages of working life. A structural equation model is utilised in order to derive a composite and continuous index of the latent health status from qualitative health status indicators. The endogenous relationship between health status and household income status is taken into account by using IV estimators. The findings reveal a significant effect of individual household income on health before and after endogeneity is taken into account and after a host of other factors which is known to influence health, including hereditary factors and the individual‘s locus of control. Importantly, it is also shown that the childhood socioeconomic position of the individual has long lasting effects on health as it appears to play a significant role in determining health during the later stages of working life.

The role of career adaptability and work conditions on general and professional well-being.

This study, conducted with a representative sample of employed and unemployed adults living in Switzerland (N = 2002), focuses on work conditions (in terms of professional insecurity and job demands), career adaptability, and professional and general well-being. Analyses of covariance highlighted that both unemployed and employed participants with low job insecurity reported higher scores on career adaptability and several dimensions (notably on control) than employed participants with high job insecurity. Moreover, structural equation modeling for employed participants showed that, independent of work conditions, adaptability resources were positively associated both with general and professional well-being. As expected professional outcomes were strongly related to job strain and professional insecurity, emphasizing the central role of the work environment. Finally, career adaptability partially mediated the relationship between job strain and professional insecurity, and the outcome well-being.
