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

Organization and use of the mental lexicon by deaf and hearing individuals   总被引:7,自引:0,他引:7  
Two experiments explored the taxonomic organization of mental lexicons in deaf and hearing college students. Experiment 1 used a single-word association task to examine relations between categories and their members. Results indicated that both groups' lexical knowledge is similar in terms of overall organization, with associations between category names and exemplars stronger for hearing students; only the deaf students showed asymmetrical exemplar-category relations. Experiment 2 used verbal analogies to explore the application of taxonomic knowledge in an academically relevant task. Significant differences between deaf and hearing students were obtained for six types of analogies, although deaf students who were better readers displayed response patterns more like hearing students'. Hearing students' responses reflected their lexical organization; deaf students' did not. These findings implicate the interaction of word knowledge, world knowledge, and literacy skills, emphasizing the need to adapt instructional methods to student knowledge in educational contexts.  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

Responses to an unfamiliar adult were examined in infants of mothers with social phobia ( N = 79) and infants of nonanxious comparison mothers ( N = 77) at 10 and 14 months in a social referencing paradigm. On each occasion, a female stranger first interacted with the mother and then approached and interacted with the infant. Over time, infants of mothers with social phobia showed increasing avoidance of the stranger, particularly when they were behaviorally inhibited. In boys, maternal social phobia was associated with increasing fearful responses. Infant avoidance was predicted by expressed maternal anxiety and low levels of encouragement to interact with the stranger. The findings are discussed in relation to theories concerning the intergenerational transmission of social anxiety.  相似文献

The California State University (CSU) system has a history of consortial purchasing of electronic resources. Its most recent endeavor is consortial Patron Driven Acquisition (PDA) of e-books. Two PDA e-book pilots, funded by the CSU Chancellor's Office, were conducted in 2011 and 2012. The aim of the pilots was to reduce duplication of e-books on CSU campuses, and determine if consortial PDA is appropriate for the CSU. This article provides an overview of CSU's cooperative collection development efforts, results from both pilots, and addresses how a consortial PDA program affects collection development locally on one CSU campus.  相似文献
