Eating problems are highly prevalent and seem to show continuity in children. Nevertheless, the effect of different maternal and paternal feeding practices on changes in these problems is not fully understood yet. This study examines short-term continuity in primary school children’s overeating, loss of control (over eating), restraint and concerns (about eating, body shape and weight) and the predictive value of parental feeding strategies on change in these eating problems. Children (8–12 years, n = 613, 46.5 % girls) completed the Child Eating Disorder Examination Questionnaire (ChEDE-Q) twice with the second measurement (T2) taking place 6 months after the first (T1). Parents (n = 714, 57.7 % mothers) completed the Child Feeding Questionnaire (CFQ) at T1 to assess the level of controlling feeding strategies. More overeating, restraint and concerns at T1 predicted higher levels of the same eating problems 6 months later, whereas more of loss of control at T1 predicted lower levels of loss of control 6 months later. Additionally, the interaction between maternal pressure and the gender of the child was predictive for increases in overeating, whereas the interaction between paternal monitoring and gender of the child was a marginally significant predictor for decreases in overeating. These findings point to the possible negative and positive effects of parental feeding practices as well as to the possible larger influence of mothers on their daughters’ and of fathers on their sons’ eating behaviors. The importance of studying mothers and fathers, as well as daughters and sons, and of including different feeding strategies and eating problems is discussed.  相似文献

The construct of autonomy has a rich, though quite controversial, history in adolescent psychology. The present investigation aimed to clarify the meaning and measurement of adolescent autonomy in the family. Based on theory and previous research, we examined whether two dimensions would underlie a wide range of autonomy-related measures, using data from two adolescent samples (N = 707, 51 % girls, and N = 783, 59 % girls, age range = 14–21 years). Clear evidence was found for a two-dimensional structure, with the first dimension reflecting “volition versus pressure”, that is, the degree to which adolescents experience a sense of volition and choice as opposed to feelings of pressure and coercion in the parent–adolescent relationship. The second dimension reflected “distance versus proximity”, which involves the degree of interpersonal distance in the parent-adolescent relationship. Whereas volition related to higher well-being, less problem behavior and a secure attachment style, distance was associated mainly with more problem behavior and an avoidant attachment style. These associations were not moderated by age. The discussion focuses on the meaning of adolescent autonomy and on the broader implications of the current findings.  相似文献

Adolescents are exposed to images depicting the thin or muscular ideal almost on a daily basis. When the body perfect ideal is adopted, adolescents are at increased risk for developing unhealthy and disordered eating behaviors. The aim of the current 3-wave longitudinal study among adolescents (N = 418; 54 % girls) was to investigate whether different styles of identity exploration (i.e., information-oriented, normative, and diffuse-avoidant) are associated differentially with changes in adoption of the body perfect ideal, which, in turn, would relate to changes in appearance-focused and health-focused eating regulation. Results indicated that the information-oriented style predicted decreases and the normative style predicted increases in adoption of the body perfect ideal. In turn, adoption of the body perfect ideal predicted significant increases in appearance-focused eating regulation but not in health-focused eating regulation. A diffuse-avoidant style was unrelated to changes in adoption of the body perfect, yet directly predicted decreases in health-focused eating regulation. Theoretical and clinical implications of these findings are discussed.  相似文献

Previous research highlights what managers perceive to be the purposes of public involvement in public-private partnerships (PPPs) and the need for addressing stakeholder concerns unique to PPPs. Yet, we have little evidence of how particular modes of participation benefit particular goals of participation in this context. Through canonical correlation analysis (CCA) of survey data collected in the U.S., this study examines the modes and sequencing of 14 public involvement activities in respect to 10 goals of public involvement in this context. The results indicate that selections among modes of participation are contingent upon when they are introduced. Respondents prefer widening stakeholder involvement early in the project development phase and during the contract implementation phase, but not during the later phases of contract design. Respondents also assign more value to engaging local citizens than their respective political leaders, particularly at mature stages of the PPP’s implementation phase.  相似文献

This article seeks to explain South Africa's ostensible emergence as a middle power. It makes the case for the use of a Coxian-based critical theory perspective, which relates the interrelationship between change at the level of world order, the nature of production and the social forces operative in the middle power's state-societal complex to explain South Africa's increasingly active role in international affairs. Playing a mediatory role helps the South African state make diverse foreign policy goals more compatible and it also goes some way in thwarting criticism levelled at its foreign policy in the state-societal domain. Contrary to earlier theorising about middle powers, this article supports a more recent contention that middle powers act in their own (ie dominant societal) interests. The value of such a perspective is illustrated in the light of current debates about the apparent incongruity of South African foreign policy.  相似文献

Public organizations face a multitude of challenges that force them to innovate existing processes, policies, programs, and products. Indeed, in recent years, innovation has become a core topic of study in public administration. However, the vast majority of the public sector innovation literature stems from the United States and Western Europe. The lack of Asia-Pacific studies is particularly striking given that countries like Australia, China, Japan, New Zealand, South Korea, Singapore, and Taiwan consistently rank high on public sector innovation. This special issue brings together state of the art empirical research on public sector innovation in the Asia-Pacific region that examines a range of drivers and outcomes of innovation, including studies comparing Asia-Pacific countries and countries in the East and the West. The findings show that public sector employees in the studied countries all seek opportunities to innovate, whereas cultural norms and values either constrain or enable innovative behaviour and affect the extent to which employees experience leadership support for displaying such behaviour.  相似文献

ABSTRACT

This article addresses the need for critical approaches to social media by bridging the focus on language and other semiotic resources that characterises discourse studies with the broader perspective on social media as social, cultural, economic and technological constructs that dominates media and cultural studies. Specifically, we propose a model for analysing how social media as semiotic technologies, that is, technologies designed to enable and constrain meaning-making, may transform social practices. By incorporating Van Leeuwen’s [2008. Discourse and Practice: New Tools for Critical Analysis. London: Oxford University Press] framework for the critical analysis of discourse and social practice, the model extends the social semiotic approach developed in recent critical multimodal studies of software such as PowerPoint to social media, which function primarily to provide platforms for and commodify social practices, rather than to offer rich arrays of semiotic resources for creating multimodal texts and artefacts. Using the academic social network site ResearchGate and the practice of research peer review, we illustrate the model’s capacity to account for the ways the design of social media platforms – through the semiotic resources they make available and the ways these are presented – enables and constrains their users’ ability to perform key social practices and has the potential to transform these practices.  相似文献
