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

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

Major findings from the Canadian incidence study of reported child abuse and neglect 总被引:1,自引:0,他引:1
OBJECTIVE: To present key findings from the Canadian Incidence Study of Reported Child Maltreatment (CIS) in sufficient detail to provide a basis for international comparisons in terms of forms and severity of maltreatment and the age and sex of victims. METHOD: A survey conducted in a random sample of 51 child welfare service areas across Canada tracked child maltreatment investigations conducted during the months of October to December 1998, produced a national sample of 7672 child maltreatment investigations. Information was collected directly from investigating workers on child and family background, perpetrator characteristics, severity and types of maltreatment and service and court outcomes of investigations. RESULTS: Forty-five percent of investigations were substantiated and in a further 22% of investigations maltreatment remained suspected. Primary reasons for investigation were physical abuse (31%), sexual abuse (11%), neglect (40%), and emotional maltreatment (19%). A larger proportion of physical abuse cases are isolated incidents involving older children and are more likely to lead to injuries. Sexual abuse, neglect and emotional maltreatment involve more chronic situations with children showing signs of emotional harm. Rates of investigated and substantiated maltreatment are lower in Canada compared to the United States, but are higher than rates reported in Australia. CONCLUSIONS: The CIS provides much needed information for developing a better understanding of the profile and needs of children and families investigated by child welfare authorities in Canada. The study also serves as a point from which international comparisons can be made. 相似文献

Social and emotional learning (SEL) is the process of integrating cognition, emotion, and behavior in our lives. In school settings, it involves systemic practices to incorporate SEL into leading, teaching, learning such that adults and children build self- and social awareness, learn to manage their own and other’s emotions and behavior, make responsible decisions, and build positive relationships. Here, we describe RULER, a systemic evidence-based approach to SEL, including its Theory of Change, and key theories that are foundational to the approach. RULER’s implementation model also is described, which involves training for school leaders, educators, and staff; integrating SEL into the curriculum across grade levels; infusing SEL into schoolwide practices and policies; and engaging families and the broader community. RULER’s current and expected outcomes for children and adults are reviewed, including both proximal (e.g., more developed emotion skills and enhanced classroom climate) and distal (e.g., reduced teacher stress and burnout and greater academic performance) outcomes. RULER’s future directions also are discussed. 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
