Variation in the timing of pubertal maturation may result in behavioral differences among early, mid-, and late maturers. Using data from the National Health Examination Survey, a national probability sample of children and youth aged 12–17, we investigated the relationships between maturational timing and body image, school behavior, and deviance. In terms of body image, the early maturing boys were the group most satisfied with height and weight. The early maturing girls were most dissatisfied with weight, with 69% wishing to be thinner. This great dissatisfaction with weight reported by early maturing girls is probably not an affect of early maturation, but a concomitant of maturation in general. The majority of girls became dissatisfied with their weight as they matured, and females from the higher social groups were more likely to want to be thinner than females from lower groups. Thus, a normal developmental process is being viewed negatively by females and positively by males. Male early maturers more often had deviant behavior, but there were no consistent findings for girls. There was no effect of maturational timing on teacher reports of school absence, adjustment, popularity, need for discipline, or grade repetition.This research was supported by the Stanford Center for the Study of Youth Development and by the Robert Wood Johnson Foundation.Received M.D. from The Medical College of Pennsylvania.Received Ph.D. in anthropology from Stanford University.Received Ph.D. in sociology from the University of Chicago.Received M.D. from Columbia College of Physicians and Surgeons.Received Ph.D. in psychology from Harvard University.  相似文献

Regulating private actors’ participation in policy‐making is key to democratic governance. Across political systems, targeted transparency is used to regulate lobbying activities. We examine the extent to which primary regulatory targets (organizations with frequent access to policy‐makers) support the architecture of lobbying regulation regimes set up as voluntary transparency clubs. Our empirical testing ground is the European Union. We conceptualize the EU Transparency Register as a Voluntary Transparency Club, elaborate on its club goods, and derive a set of theoretical expectations about its members’ evaluations of the club's transparency standards, membership size, and monitoring and enforcement mechanisms. We find significant differences between members’ and non‐members’ assessment regarding the regulatory performance of this transparency club. Members with frequent access to executive policy‐makers criticize the club's transparency standards and do not consider the Register a useful regulatory instrument. Yet, they support expanding its regulatory remit and increasing the club membership.  相似文献

Fragmentation and specialization—two characteristics of governance—have increased the number and variety of actors involved in the governing process, which can influence policy outcomes and legitimacy. To date, studies on governance or policy networks usually focus on one policy field and one moment in time. In this article, we analyse the dynamic aspect, thus how governance networks change over time, and examine whether the fragmentation and specialization of the governance system is mirrored in the circulation of public officials. Our case is the urban governance system of the Paris region, which is characterized by high fragmentation along policy fields and territory. The data show that Paris is governed by three sub‐systems that largely correspond to the different territorial levels of governance, but also to different types of organizations. Generally, territorial fragmentation seems to be stronger than policy field fragmentation. This structure is quite stable across time.  相似文献
