“…Several authors have pointed out that there are perceived negative features which limit the purchase of green products, including price, quality, performance, availability, and convenience (D'Souza et al, 2007;Wagner, 1997). These factors may also be significant as mediators or moderators of the relationships between the variables of a model (Abbad & Torres, 2002;Shrout & Bolger, 2002;Vieira, 2009). This could explain why environmental intentions might not lead to green product purchase behavior.…”

ANDRES RODRIGUEZ VELOSO 13ABSTRACT Purpose: 1. to investigate if a difference is found between university students of both countries. 2. to provide an analysis of the attitudes, intentions, and behavior of Brazilian and Canadian university students regarding the purchase of green products. Originality/value: The relevance includes a cross-cultural study between Brazil and Canada and its possible use as a tool for educators in the Business area seeking to develop curricula that will prepare students for future roles in management. The study may also stimulate other research on green product markets. Moreover, it should be useful to managers in developing corporate environmental management systems in large and small organizations, as well as to professionals seeking to develop marketing strategies based on the behavior of their consumers. Design/methodology/approach: Data analyses were conducted using confirmatory factor analysis and structural equation modeling. Findings: The study demonstrated the positive and direct relationship between intention and behavior. The literature notes incentives and stimuli to promote purchase behavior through features, such as quality, price, and availability. These are key factors in the relationship between intention and purchase behavior. KEYWORDSConsumer behavior. Purchase intention. Green products. Brazil. Canada.

“…This means the proposition of a moderation ratio and multiple regressions can be used to identify moderating variables. To test the proposed moderation, Abbad and Torres (2002) stated that it must be observed, if A is a good predictor of C. If so, it checks if A and B predict C, and the interaction between A and B, calculated by the product A × B, also predicts C. If the interaction is a statistically significant predictor of C, B is a moderating variable. In this research, it can be assumed that the variables "well-being at work", "job satisfaction", and personal and professional variables assumed the role of A, the variable "individual job performance" assumed the role of C, and variable "components of organizational structure" assumed the role of B.…”

The hypothesis "happy productive worker" states that happy employees, whose needs are satisfied in their workplace, have greater performance than unhappy employees. Therefore, the purpose of this research is to examine empirically the effects that job satisfaction and well-being at work generate on the individual job performance, investigating the moderating role that the components of the organizational structure play in this relationship. To achieve the main objective, some secondary objectives were proposed: (1) test the predictive effect of well-being, satisfaction, personal, and professional variables on individual performance; and (2) test the moderating effect of the components of the organizational structure in the relationship among well-being, satisfaction, and individual job performance. This research originates of a consolidated statement for the business society, but very few empirical studies. This way, the hypothesis consisted in the components of the organizational structure will positively enhance the relationship among well-being at work, job satisfaction, and individual job performance. The final sample consisted of 134 participants, of a clinical laboratory and of federal court of justice.For the development of the questionnaire, four instruments were used; one for each construct. The proposal has four relationship variables and the statistical procedure used to test this hypothesis was multiple linear regressions.Considering the hypothetical theoretical model presented, personal and professional variables are predictors of job performance; thus, these variables were also included as independent variables. The results of the regression model showed that the variables "age", "well-being at work", "job satisfaction", and "components of organizational structure" are responsible for explaining 64% of the variance of the variable criteria and individual job performance.The moderating role of the variable "components of organizational structure" was also observed, because its inclusion increased the explained variance of the dependent variable. After all the discussions developed, the two main contributions appear: (1) the predictive effect of well-being at work in relation to performance and (2) identifying the moderating effect of the components of the organizational structure.

“…Somehow this effect could be latent in EI, IE and POE response, not allowing the achieving of conjectured results. Another effect that attention should be given in these circumstances is the redundancy effect [65]. As can be verified in Table 2, EI and IE exhibit a strong positive correlation (r = 0.278, p < 0.01), leading to as stated by Reference [65] the loss of parsimony in difference explanation between IE and POE.…”

“…In the second step was added the potential moderator variable EI, and the multiplicative term in the third step, in order to capture the interaction between EI and IE (EI × IE) according to Reference [64], Reference [63]. The tests to analyze moderators' effects are usually performed through hierarchical regressions [65]. The difference between IE and POE reports was calculated by the indicator (IE-POE), used as dependent variable in the moderated regression analysis.…”
