This study used a trait-state-occasion (TSO) model to isolate stable trait variance, occasion-specific state variance, and shared method related variance in a measure for leisure satisfaction in a Dutch nationally representative nine-year panel study. Findings indicate that satisfaction with leisure time is a consistently stronger indicator of overall leisure satisfaction than satisfaction with leisure activities. About half of the variance in leisure satisfaction is stable trait variance, with the remaining variance being mostly occasion-specific and to a lesser extent attributable to shared method variance and error. However, these findings depend on the age group we consider.Several socio-demographic variables relate directly to the trait aspect of leisure satisfaction. Our study underscores the importance of recognizing that over time leisure satisfaction measurements have considerable stable and more volatile elements and that one should control for shared method effects.

Obesity and other lifestyle-related diseases are, amongst others, the result of an unbalanced diet and lifestyle. Excessive intake of energy, salt, saturated fat and sugar are leading to increased risk of chronic diseases, such as cardiovascular diseases, cancer and diabetes (WHO/FAO). Therefore, a healthier food intake (diet) is needed. But when is a food product healthier? From a nutritional perspective it is clear: the lower the levels of nutrients with a negative public health impact, the better the product fits in a healthy diet. However, when it comes to improving the health impact of the food supply through reformulation, other aspects are important as well. This article describes the ‘framework for product reformulation’, which integrates four essential disciplines: Nutrition & health, Foodtechnology, Legislation and Consumer perspective.

Learning teams in higher education executing a collaborative assignment are not always effective. To remedy this, there is a need to determine and understand the variables that influence team effectiveness. This study aimed at developing a conceptual framework, based on research in various contexts on team effectiveness and specifically team and task awareness. Core aspects of the framework were tested to establish its value for future experiments on influencing team effectiveness. Results confirmed the importance of shared mental models, and to some extent mutual performance monitoring for learning teams to become effective, but also of interpersonal trust as being conditional for building adequate shared mental models. Apart from the importance of team and task awareness for team effectiveness it showed that learning teams in higher education tend to be pragmatic by focusing primarily on task aspects of performance and not team aspects. Further steps have to be taken to validate this conceptual framework on team effectiveness.
