Ecological research can augment restoration practice in urban areas degraded by invasive species—examples from Chicago Wilderness 总被引:1,自引:1,他引:0

Urban biodiversity conservation needs a firm scientific foundation, one that draws upon active and regionally calibrated research
programs. Until recently this foundation has not existed. In this paper we examine the way in which the emerging discipline
of restoration ecology in an urban context can learn from the experiences of ongoing restoration projects and in turn how
novel insights from research of urban soils can help these projects define and reach their goals. Limitations on collaboration
between academic researchers and practitioners continues be problematic. We discuss a model whereby this impediment may be
removed. A case study of Rhamnus cathartica, an invader of Midwestern woodlands which modifies some important soil ecosystem properties will be used to illustrate the
potential for engagement between research and practice. 相似文献

This paper critically reviews recent research exploring risk and protective factors for the development of problematic substance use in populations of young people. Specific populations of young people who are most vulnerable to developing problematic patterns of use are identified, and alterations to methods of data collection which would improve the ability of local authorities to monitor these populations and more efficiently target them for early preventative interventions are highlighted. It is argued that social‐psychological research techniques and approaches should be used to complement a risk and protection‐focused approach in order to improve the design and evaluation of interventions, and provide decision‐aids for practitioners when assessing the needs of vulnerable young people. Examples are provided to demonstrate the utility of social psychology in this regard, and the paper concludes with specific recommendations for future research and services.

In this longitudinal study we examined whether two components of effortful control, behavioral control, and executive function moderated the relation between temperament and conscience development. Temperament was assessed when participants were two years of age, and three temperament groups were formed: inhibited, exuberant, and low reactive. At 4.5 years of age, children's behavioral control and executive function were assessed. Moral behavior, emotionality during an empathy film, and false-belief understanding were measured at 5.5 years of age as components of conscience. Results indicate that inhibited children may benefit most from higher levels of effortful control. Inhibited children with higher levels of behavioral control performed better on false-belief understanding tasks whereas inhibited children who scored higher on executive function tests reported less emotional response to the evocative film. Finally, as a group, inhibited children exhibited more moral behavior than exuberant and low reactive children. 相似文献

Research suggests that non-linguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a three-location spatiotemporal sequence of multi-colored geometric shapes. Early language skills were assessed using the MacArthur-Bates CDI. Analyses of children's reaction times to the stimuli suggest that the extent to which infants demonstrated learning was significantly correlated with their vocabulary comprehension at the time of test and with their gestural comprehension abilities 5 months later. These findings suggest that visual sequence learning may have both domain-general and domain-specific associations with language learning. 相似文献

ABSTRACT The purpose of this study is to evaluate the potential of college towns as retirement communities. The uniqueness of college towns as potential retirement communities are identified and discussed. Differences between college towns and Sunbelt state retirement destinations regarding the factors that are most concerned by retiree migrants in their decision-making for relocation were compared. The results showed no differences between the college towns and the Sunbelt state retirement cities. Only a few differences existed among the college town subgroups. The findings are of value to the senior living industry, local government and chamber of commerce in their efforts in marketing college towns as prospective retirement communities. 相似文献
