There is a serious misconception on the part of the public as well as amongst a great number of professionals to equate the problem of flatfoot with excessively pronated feet in growing children. This is a matter of grave concern since flatness of the arch of the foot can be a normal or abnormal finding in foot posture, whereas the excessively pronated foot is flattened as part of a pathological structural malposition. This inherent biomechanical defect is commonly present in the great majority of human children and is the basic reason for most postural pathology of the lower extremity.Excessive pronation of the feet in children should in no way be interpreted as a normal condition to be automatically outgrown. As a matter of fact, Whitman, the famous Orthopaedic Surgeon, noted in 1917 in his text Orthopaedic Surgery that pronation of the feet commonly seen in children is more likely to worsen than improve over the years. This paper presents the probable cause of the condition, treatment and prevention of the problem and recommendations for the future.The deforming foot posture known as excessive pronation is familiar to Podiatric Medicine and to Medicine generally. Yet, in spite of this familiarity, only an insignificant number of the millions of children in our country receive the simple available help required to minimize the problem.The Podiatric profession has within its grasp the wherewithal to correct this situation, through education and counseling of parents, through cooperation with pediatricians and other professionals and by utilizing technological advances in children's footgear and orthotics. It is the intention of this paper to provide an overview of the literature and history associated with the problem of excessive pronation in children, as well as to suggest some simple techniques for improving this situation.Dr. Tax is an international renowned consultant to many Podiatric Hospital amon which is the Veterans Administration in New Jersey, New York College of Podiatric Medicine, Ohio College of Podiatric Medicine. He has written and lectured extensively on the subject of children and problems with their feet. 相似文献

The authors consider the correlation between two arbitrary functions of the data and a parameter when the parameter is regarded as a random variable with given prior distribution. They show how to compute such a correlation and use closed form expressions to assess the dependence between parameters and various classical or robust estimators thereof, as well as between p‐values and posterior probabilities of the null hypothesis in the one‐sided testing problem. Other applications involve the Dirichlet process and stationary Gaussian processes. Using this approach, the authors also derive a general nonparametric upper bound on Bayes risks. 相似文献

Two types of bivariate models for categorical response variables are introduced to deal with special categories such as ‘unsure’ or ‘unknown’ in combination with other ordinal categories, while taking additional hierarchical data structures into account. The latter is achieved by the use of different covariance structures for a trivariate random effect. The models are applied to data from the INSIDA survey, where interest goes to the effect of covariates on the association between HIV risk perception (quadrinomial with an ‘unknown risk’ category) and HIV infection status (binary). The final model combines continuation-ratio with cumulative link logits for the risk perception, together with partly correlated and partly shared trivariate random effects for the household level. The results indicate that only age has a significant effect on the association between HIV risk perception and infection status. The proposed models may be useful in various fields of application such as social and biomedical sciences, epidemiology and public health. 相似文献

Cultural capital or relative risk aversion? Two mechanisms for educational inequality compared1 总被引:2,自引:0,他引:2
In this paper we empirically examined two explanatory mechanisms for educational inequality: cultural reproduction and relative risk aversion, using survey data taken from secondary school pupils in Amsterdam. Cultural reproduction theory seeks to explain class variations in schooling by cultural differences between social classes. Relative risk aversion theory argues that educational inequalities can be understood by between-class variation in the necessity of pursuing education at branching points in order to avoid downward mobility. We showed that class variations in early demonstrated ability are for a substantial part cultural: cultural capital - measured by parental involvement in highbrow culture - affected school performance at the primary and secondary level. However, relative risk aversion - operationalized by being concerned with downward mobility - strongly affects schooling ambitions, whereas cultural capital had no effect. Thus, we conclude that 'primary effects' of social origin on schooling outcomes are manifested through cultural capital and not through relative risk aversion (in addition to other potential sources of class variations such as genetics). Relative risk aversion, and not cultural capital, affects schooling ambitions, which is relevant for our understanding of secondary effects. 相似文献

In this article, we propose a weighted simulated integrated conditional moment (WSICM) test of the validity of parametric specifications of conditional distribution models for stationary time series data, by combining the weighted integrated conditional moment (ICM) test of Bierens (1984) for time series regression models with the simulated ICM test of Bierens and Wang (2012) of conditional distribution models for cross-section data. To the best of our knowledge, no other consistent test for parametric conditional time series distributions has been proposed yet in the literature, despite consistency claims made by some authors. 相似文献

Previous research suggests that when there is a high level of inequality, there is a low rate of participation. Two arguments are generally offered: First, inequality depresses participation because people from different status groups have fewer opportunities to share common goals. Second, people may participate more in civic and social life when they have more resources. However, until now, these explanations have not been separated empirically. Using EU-SILC data for 24 European countries, we analyze how income inequality is related to civic and social participation. Our results indicate that the main effects of inequality manifest via resources at the individual and societal level. However, independent of these resources, higher inequality is associated with lower civic participation. Furthermore, inequality magnifies the relationship between income and participation. This finding is in line with the view that inter-individual processes explain why inequality diminishes participation. 相似文献

A Harvey Wallbanger is an alcoholic drink composed of three ingredients: orange juice, vodka, and Galliano. One of the authors (Sahrmann), a connoisseur of the libation, was perplexed upon discovering that different bartender handbooks listed different recipes for the drink. Determined to shed some light on this irksome problem, he issued invitations for an evening workshop session (party) to former and current attendees of an experimental-design training course taught within his company. A mixture experiment was designed and data collected using the class participants. This article describes the experimental design and the analysis of the data. The results of the experiment indicate that reducing the proportion of vodka produces better-flavored drinks. The results of the experiment were not entirely conclusive, however, so recommendations are made for future experimentation. 相似文献
