This research documents a “light = healthy” intuition, such that consumers perceive foods that weigh less are healthier than their heavier counterparts with the same serving size. Subsequently, consumers consume a larger quantity of lighter-weight foods. The intuition is based on a coactivation of two meanings of the word “light”: light in physical weight and light in calorie content. An implicit attitude test finds support for this association between physical weight and food healthiness. ​Subsequently, physically lighter foods are perceived to be healthier because they are assumed to contain fewer calories. In line with the proposed coactivation mechanism, the intuition is bidirectional, where consumers also expect healthier foods to weigh less. Consequently, they discredit health claims issued for heavier foods. Finally, it was found that activating a competing intuition is effective at debiasing the “light = healthy” intuition.  相似文献

IntroductionPersonality traits can give a fuller understanding for eating behaviors, such as food choice, (un)healhty eating.ObjectiveTo examine eating styles with a multidimensional perspective considering cognitive, affective and conative (or behavioral) components of eating styles in emerging adulthood, and how they may be related to the Big Five and impulsivity traits.MethodsSelf-reported questionnaires were used to explore the association between the eating styles, Big five traits and facets of impulsivity among young French adults (n = 450; Mean Age = 20.84 years; SD = 2.4, with 79.6% of women).ResultsOn the basis of cluster analysis, six eating styles were identified: Healthier, Uninhibited, Dysregulated, Stress-related, Restrictive and Ethical restraint eaters. Results suggest that Uninhibited eaters reported lower scores on Conscientiousness and higher scores on Negative and Positive urgency. The Dysregulated group had lower scores on Extraversion, and high scores on Neuroticism, Negative urgency and Lack of premeditation. Restrictive eaters showed low levels of Openness and Lack of premeditation. The Ethical restraint style was characterized by low scores on Agreeableness and Positive urgency. The ability or inability to cope with both emotional distress and positive and negative impulsive behaviors was related to young adult's eating cognitions and behaviors.ConclusionConsidering the existence of subtypes of eaters and separate associated personality-related traits, an individual differences perspective (e.g., age, gender, disposition to control one's emotional experiences) should be incorporated.  相似文献

Abstract: The evolution of the U.S. war on terrorism is on a path that poses a substantial probability of losing to it, although not necessarily of a victory by its declared targets. That conclusion follows from the definition presented of terrorism and thus central questions about the merits of responses justified by an objective of reducing it. Likely American responses to 9/11 are suggested by a review of well‐known policy‐making tendencies from past scholarship and experience, tendencies well‐established prior to 9/11 and by no means unique to the Bush II presidency. The expectations those tendencies suggest have been born out by what the United States has done and not done. Well‐established criteria and their implied rules of practice for security enhancing great‐power statecraft are presented, and the chosen U.S. program of action is found to be counter‐productive in their light.  相似文献

Human trafficking is a critical social issue characterized by chronic trauma among victims, and frequently preceded by traumatic experiences that contribute to risk of victimization. Therefore, the research‐based practice of trauma‐informed care is a highly appropriate lens for both prevention and intervention. This work examines federal legislation in the United States related to human trafficking for references to trauma, as well as how the use of research could implicitly direct public policy responses toward trauma‐informed approaches. Legislation on human trafficking has risen substantially since 1989, and the use of research and trauma language within these policies has also observed substantial increases. While the use of trauma language was associated with limited progression in the policy process, legislation using research language was more likely to pass out of Committee and become enacted. Moreover, legislation may leverage research in ways that have the potential to bolster trauma‐informed practice among human trafficking victims. Specifically, research can be used to describe the problem and causal mechanisms (e.g., impact of trauma), guide “best practice” for service delivery, and generate knowledge through studies and evaluations that guide future policy. Therefore, human trafficking legislation that implicitly guides trauma‐informed practice via the use of research may be particularly promising for the field.  相似文献

Peter Hall introduced the concept of paradigm shifts into the public policy discourse. His account explains the seismic transition the world experienced in the 1980s. With this neoliberal paradigm the former social contract between the public leadership and the people unraveled and the future of humanity has been put at risk. To steer humanity back in the direction of a sustainable future, the author argues for a participatory public policy paradigm instituted as a reinvention of Rousseau’s social contract theory with tree distinct features that respond to the complexity of life in modern times.  相似文献

Children and youth in neighborhood contexts   总被引:3,自引:0,他引:3  
Neighborhoods are increasingly studied as a context where children and youth develop; however, the extent of neighborhoods' impact remains debatable because it is difficult to disentangle this impact from that of the family context, in part because families have some choice as to where they live. Evidence from randomized experiments, studies using advanced statistical models, and longitudinal studies that control for family characteristics indicates that neighborhoods do matter. In nonexperimental studies, small to moderate associations were found, suggesting that children and adolescents living in high-income neighborhoods had higher cognitive ability and school achievement than those living in middle-income neighborhoods, and children and adolescents living in low-income neighborhoods had more mental and physical health problems than those living in middle-income neighborhoods. The home environment has been shown to be partly responsible for the link between neighborhood and children's development. For adolescents, neighborhood effects are partially accounted for by community social control. Experimental studies in which families were randomly assigned to move to low-poverty neighborhoods from housing projects found larger neighborhood effects than nonexperi-mental research, particularly for boys' outcomes. Additional issues reviewed are relevant neighborhood characteristics, theoretical models explaining the pathways underlying neighborhood effects, methods for research assessing neighborhood processes, and policy implications.  相似文献

The Cornell Institute for Research on Children (CIRC) is an intellectual infrastructure funded by the National Science Foundation under the aegis of the Children's Research Initiative, which was spearheaded by Rodney R. Cocking. Cocking's vision of integrated developmental science is an integral part of CIRC's philosophy. CIRC aims to integrate knowledge and paradigms from a variety of fields (e.g., developmental psychology, economics, neuroscience, and pediatrics), which take different perspectives on similar issues (e.g., the effects of toxins on cognitive development), making it explicitly interdisciplinary. The object of CIRC studies is to apply research findings to social policy. To accomplish this, CIRC provides resources to enable teams of scholars from diverse fields to collaborate on policy-relevant questions. CIRC's approach begins by asking policy-makers to define questions for researchers to address, then shepherds the process by which scholars from various relevant disciplines are commissioned to work as a team to answer such questions. To demonstrate the strengths of this approach we describe the six components that comprise CIRC and provide an actual example of a project that CIRC has commissioned as well as a hypothetical example of a project that CIRC could undertake. This article is a progress report, written in an effort to disseminate information about CIRC's agenda.  相似文献

The primary goal of this study was to examine the applicability of preference‐based segmentation for a broad array of meals in the context of teenagers. A representative sample of 1,168 Norwegian schoolchildren provided an evaluation of 20 common dinner meals in terms of preference (liking). Cluster analysis was used to establish four distinct preference‐based food segments. These four segments were termed Food Lovers, Fish Haters, Fish Lovers and Dislikers. The relationship between these four preference‐based segments and demographic, consumption, attitude and lifestyle variables was finally modelled using a multinomial logit analysis. The results highlight the fact that social and family‐related attitude and lifestyle variables have a greater ability to profile the segments and explain segment membership than demographic variables. The findings indicate that there are distinct and interesting differences between these segments. The findings have some implications for marketers within the industry in terms of effectively targeting the different market segments. Copyright © 2004 Henry Stewart Publications Ltd.  相似文献

The essay starts by presenting two accounts of begging the question, John Biro's epistemic account and David Sanford's doxastic account. After briefly comparing these accounts, the essay will study an argument suspected of begging the question and subsequently apply the epistemic and doxastic accounts to this test case. It is found that the accounts of Biro and Sanford do not analyse the test case adequately, therefore a new account is developed using the idea of a knowledge-base.  相似文献
