The role and continued relevance of state telecommunications regulators have been challenged by the development of competition, the introduction of new technologies, and the increasing dominance of federal authority. An important role that state utility commissions can play in the current telecommunications environment is to provide consumer education and information about consumer protection, competition, and universal service. Commissions can use their Web sites as effective tools in educating and informing consumers. This study analyzes the consumer-related telecommunications information included on the Web sites of the commissions in the 50 states and the District of Columbia to determine whether, and how well, state commissions are using their Web sites to educate and inform. 相似文献

Interest in promoting positive development among children and adolescents has always been a focus of developmental science. Historically, many researchers framed this interest using a deficit model that sought to optimize positive development by reducing problems. In the context of the articles in this special section, the author discuss a different conception of positive youth development that has emerged across the past 25 years, one that capitalizes on human plasticity and tests a strength‐based model (instead of a deficit one). This model seeks to identify the process that could enhance the attributes of young people that are valued by them and others (e.g., parents, peers, teachers, mentors, coaches, and faith leaders), as compared to processes that reduce or prevent undesirable characteristics. 相似文献
