While nature center’s missions often point to connecting people to nature in various ways, their potential to provide a broader array of services to their communities remains largely unexplored. To better understand the values local community members hold for nature centers, we conducted survey research around 16 centers in the United States. Exploratory factor analysis identified four underlying values: environmental connection, leisure provision, community resilience, and civic engagement. Our limited sample of community respondents felt these values to be important and well-provided by local centers, suggesting centers may play broader roles in communities than inferred from their mission statements. The identification of these distinct value sets provides centers with food for thought regarding not only the services they provide, but also how they might communicate their roles to various constituencies in their communities. The values also provide clear conceptual categories for future research on the values of diverse community institutions.  相似文献

Role models may be essential in helping students develop environmental literacy and characteristics associated with positive youth development (PYD). We examine the identities of middle school students’ self-reported role models before, immediately after, and three months following an immersive 5-day residential environmental education (EE) experience that targets environmental responsibility, character development and leadership, and attitudes toward school as programmatic outcomes. We explore whether students who identified different types of role models score differently on these factors. Students who identified parents, teachers, and pastors as role models scored higher on each of these outcomes. Moreover, who students identified as role models changed significantly after the EE program. We discuss the potential influence of the program on role model development and implications for EE and PYD programs.  相似文献

Film has become a popular form of entertainment among teenagers and provides images from which teens model behaviors and form attitudes. This study addresses the understudied area of the portrayal of teen and adult sexual behaviors over nearly three decades in the top-grossing teen-centered films from 1980 to 2007. This study analyzes the frequency, nature, character portrayals, and consequences of sexual behavior. The results show that teen-centered films are replete with passionate kissing and sexual dialogue yet contain a modicum of implied intercourse and intimate touching. Moreover, the frequency of such occurrences has remained surprisingly constant over the last three decades. This research also reveals that teen-centered films, as a source for sexual socialization, are relatively impoverished when it comes to responsible messages dealing with abstinence, safe sex practices, and the health risks associated with sex.  相似文献

ABSTRACT

Prisoner reentry is an important and timely topic which can be challenging to research because it is so wide-reaching and includes so many subtopics. The aim of this guide is to outline the basic sources and necessary strategies to begin study in this area. The main part of this guide is a list of materials limited to those that have appeared since 2000. The second part of the guide gives direction to those who want to learn more, by recommending strategies including keywords and phrases which have been found to be of use. The issues related to prisoner reentry affect all of us. Public policy, legislative changes, and community survival require a knowledgeable citizenry. This guide can direct users to the information necessary to make meaningful decisions about these sometimes controversial issues.  相似文献

This paper reports on a project that grew out of observations and conversations undertaken by two faculty members at LaGuardia Community College/CUNY interested in exploring the connection between research skills and transfer knowledge. Stern and Macheski posited that if students were able to connect research acquisition skills to the transfer application process, each skill would enhance the other. The outcomes from this small cohort, while not conclusive, lead the authors to be optimistic that their approach improves both understanding of authentic research and its connection to personal goals. National conversations in recent years about the changing role of community colleges inform this inquiry.  相似文献
