Children do not choose what to eat based on health issues alone, and the high availability of non‐nutritious food in the environment can be a barrier to the consumption of healthy foods. Brazilian children are consuming processed, savoury, rich in fat, sodium and refined carbohydrates rather than more nutrient‐dense foods. Foods offered in public school meals and those sold in private school canteens in Brazil are subject to regulation, but not the snacks brought from home. This study identified the suggestions of public and private school students about the characteristics that a snack should present in order to be considered both healthy and palatable. A qualitative exploratory study using focus groups was conducted with 128 primary school students aged 7–10 years old. Interviews were transcribed and content analysis was conducted, generating three categories: (1) foods actually consumed during snack breaks; (2) examples of foods considered healthy and/or tasty for consumption during snack breaks; and (3) desired characteristics of a healthy and tasty snack. Foods of high energy density and low nutritional value were mentioned as the most consumed snacks, usually brought from home or purchased within/near the schools. Consumption of meals offered by the National School Meal Program was reported by only one‐third of the public school students. Fruits, natural juices and vegetables were considered healthy foods; sweet‐tasting preparations containing fruits were considered tasty; while fruits and natural fruit juices were considered both healthy and tasty. Sweet‐tasting preparations containing fruits were mentioned as examples of snacks with the desired healthy/tasty characteristics. The disparity between what was actually consumed and what was reported as ideal leads us to question the availability in retail stores of healthy yet palatable foods that meet this population's desires.  相似文献

The purpose of this study was to revisit Lewin's gatekeeper theory to observe current food role patterns (cooking experience, recipe sources, and both daily food consumption choices and eating out) with contemporary groups of college students (n = 292) and of nutrition educators (n = 26). Male college students equalled female students in cooking ability, use of family as a prime recipe source, and frequency of eating out, while exhibiting different food consumption excesses and deficiencies. Package labels and the Internet were most frequently identified as recipe sources by college students. Nutritionists surpassed both male and female college students in most attributes.  相似文献

Over the past several decades, there have been some significant advances in psychological science, specifically in our knowledge about important questions to address with respect to the development and use of assessment tools. This article focuses on developments in research and guidelines for practice in five selected areas that, if applied, will lead to more informed use of assessment tools. The five areas that we discuss are validity generalization, statistical significance testing, criterion measures, cutoff scores, and cross‐validation. © 2005 Wiley Periodicals, Inc.  相似文献

This article shows how to predict counterfactual discrete choice behavior when the presumed behavioral model partially identifies choice probabilities. The simple, general approach uses observable choice probabilities to partially infer the distribution of types in the population and then applies the results to predict behavior in unrealized choice settings. Two illustrative applications are given. One assumes only that persons have strict preferences. The other assumes strict preferences and utility functions that are linear in attribute bundles, with no restrictions on the shape of the distribution of preference parameters.  相似文献

Work in the US and Canada has found the flypaper effect to be evident at the national as well as the sub-national government level. This paper uses the methodology developed by Robert R. Logan (1986) to examine how the payment of inter-governmental grants has affected government expenditure in Australia. The analysis is of both the recipient and payee governments.  相似文献

Abstract

This investigation replicates Beltramini's (1992) study of the effectiveness of business gifts, and extends the research to include actual marketplace sales response. A company's customers'perceived satisfaction and intention to continue repurchasing are surveyed both before and after being sent a more expensive gift, a less expensive gift, or no gift at all, and customers'actual sales are longitudinally tracked. The results indicate business gift-giving represents an effective part of a marketer's overall marketing communications strategy, and both limitations and implications are discussed.  相似文献
