A high prevalence of youth is overweight or obese, and a frequent lack of monitoring of their weight control strategies is observed. Consequently, this paper compares the eating habits and physical activities of male and female dieters and non-dieters. Data are obtained from the large cross-national WHO collaborative study “Health Behavior in School-aged Children 2010”. The current sample consists of 9,444 students aged 11, 13 and 15 years from England and Spain. Participants are asked about dieting, vigorous and moderate-to-vigorous physical activity, breakfast frequency and fruit, vegetable, sweet and soft drink consumption. A logistic regression is used to examine the differences between dieters and non-dieters with regard to the aforementioned eating and physical activity habits. Differences between genders, countries, and those associated with BMI (body mass index) are also considered. The results suggest that the reality of weight control differs from the major health promotion recommendations during adolescence.  相似文献

Recently, the first ever estimate of the number of children living poverty in developing countries was undertaken. The incidence of child poverty was estimated by establishing how many children suffer severe deprivation in at least one out of seven indicators which are internationally recognized as their rights as well as constitutive of poverty. This is a major step forward in the analysis of poverty. In this paper, we generalize these findings on the incidence of children living in poverty by exploring how to estimate the depth and severity of child poverty. Two countries can have the same proportion of children living in poverty, however, the actual plight of children could be very different depending on how many deprivations, on average, children suffer. In addition, even if they suffer from the same average number of deprivations, these deprivation could be the same for all children or be very unevenly distributed. We show how these considerations can be used to estimate the depth and severity of poverty. We use regional data to provide applied examples of this methodology. The method proposed in this paper is similar to the one used to estimate the incidence, depth and severity of income poverty. The paper also offers some possible generalizations and ways forward for future research.  相似文献

This study aimed to examine the gender-related differences in demographics, gambling measures, psychological functioning, and motivation for therapy in an outpatient sample of pathological gamblers seeking treatment. Participants in this multisite study included 103 adult outpatients (51 women and 52 men) meeting current DSM-IV-TR criteria for PG. Logistic regression was used to examine if gender was related together to categorical and continuous independent variables. Female gamblers were older than men and more likely to be divorced or widowed and to have a lower annual income. Women became more dependent on bingo and men on slot machines. Gambling motivation and the course of illness for both sexes were also different. Female gamblers were more anxious and with a poorer self-esteem than male gamblers and more affected by depressive symptoms; in turn, men were more impulsive and higher sensation seekers than women and more affected by drug/alcohol abuse. The 68.6% of female gamblers reported being victims of intimate partner violence. There were no gender differences about the motivation for treatment. Future research should examine gambling behaviors and psychological functioning and suggest treatment approaches to address specific goals according to these gender-related differences.  相似文献

Within the general frame of proposals for an adequate management of business ethics, this paper is based on the vision of corporate culture as a pattern to achieve such purpose. If we consider ethics as a specific value of corporate culture, we may resort to the mechanism of cultural change and implementation in order to manage ethics. Despite the difficulties it entails in terms of time and money investment, this procedure is one of the safest ways to reach ethical values which are known, shared and then practiced by all the members of a corporation, whatever the category. From this central standpoint, and basing ourselves on our own proposal for the management of culture, we shall describe which specific steps must be taken in order to achieve a set of ethical values which are both realistic and furthermore shared by all collaborators of an organization.  相似文献

We prove weak and strong laws of large numbers for coherent lower previsions, where the lower prevision of a random variable is given a behavioural interpretation as a subject's supremum acceptable price for buying it. Our laws are a consequence of the rationality criterion of coherence, and they can be proven under assumptions that are surprisingly weak when compared to the standard formulation of the laws in more classical approaches to probability theory.  相似文献

A number of studies have investigated infants' abilities to extract and discriminate number from multimodal events. These results have been mixed for several possible reasons, including aspects of the experimental design that provide perceptual cues that are unrelated to number, and are known to influence looking preferences. This experiment used a preferential looking paradigm to investigate whether 6‐ to 9‐month‐old infants can extract the amodal property of number from an arbitrarily related multimodal event sequence when nonnumerical confounds are removed. Results demonstrate that female infants discriminate number from a multimodal presentation by 6 months, whereas males do so by 8 months. Further, the study underscores the importance of controlling for low‐level perceptual cues in looking time experiments aimed at examining infants' cognitive abilities.  相似文献

In the context of the reform of defined benefit pension systems under population ageing, we focus on the introduction of automatic adjustment mechanisms linked to life expectancy. Our goal is to establish a relationship between changes in the key parameters of the pension system and changes in life expectancy, applying the principle of intergenerational actuarial neutrality. For a defined benefit pension scheme, we first obtain the fundamental adjustment equation and then, for particular cases, we derive different designs of automatic adjustment mechanisms depending on the involved parameter. We include a numerical application only for illustrative purposes.  相似文献

Some nonprofits evolve from small into large international organizations. For years, “structure follows strategy” (Chandler) has been the dictum to explain organizational strategic changes like the ones in nonprofits. But scholars also recognized organization structure to be a precondition to carry out certain strategies. Nevertheless, research on structure and strategy in nonprofits is limited. This paper explores the mutual influence of organization structure and strategy in high-performing nonprofits in Iberoamerica based on a secondary analysis of 20 unpublished research cases of the Social Enterprise Knowledge Network. It follows the research question: Which organizations’ strategies and structures characterize high-performing nonprofits over time? Four types of organizing patterns emerged: starting-up, professionalizing, decentralizing, and conglomerating.  相似文献
