Designing nature reserves: adapting ecology to real-world problems   总被引:1,自引:0,他引:1  
Kingsland S 《Endeavour》2002,26(1):9-14
Establishing nature reserves is the foundation of regional conservation strategies. The science of nature reserve design is relatively new, having emerged alongside the interdisciplinary field of conservation biology over the past three or four decades. Its goal is to apply scientific ideas and methods to the selection and design of nature reserves and to related problems, such as deciding what kinds of buffer zones should surround reserves or how to establish corridors to link reserves and allow organisms to move from one area to another. As in other areas of conservation biology, designing nature reserves is a 'crisis' science, whose practitioners are driven by an acute sense of urgency over the need to stem the loss of species caused by human population growth.  相似文献

Abstract

Considerable research evidence supports the provision of explicit instruction for students at risk for reading difficulties; however, one of the most widely implemented approaches to early reading instruction is Guided Reading (GR; Fountas & Pinnel, 1996), which deemphasizes explicit instruction and practice of reading skills in favor of extended time reading text. This study evaluated the two approaches in the context of supplemental intervention for at-risk readers at the end of Grade 1. Students (n = 218) were randomly assigned to receive GR intervention, explicit intervention (EX), or typical school instruction (TSI). Both intervention groups performed significantly better than TSI on untimed word identification. Significant effects favored EX over TSI on phonemic decoding and one measure of comprehension. Outcomes for the intervention groups did not differ significantly from each other; however, an analysis of the added value of providing each intervention relative to expected growth with typical instruction indicated that EX is more likely to substantially accelerate student progress in phonemic decoding, text reading fluency, and reading comprehension than GR. Implications for selection of Tier 2 interventions within a response-to-intervention format are discussed.  相似文献

The number of educators, administrators, and institutions that utilize social networking has increased dramatically. Many have adopted social networking in order to be up-to-date and connected with their students’ learning beyond the boundaries of the classroom. However, this increase in the use of social networking in academia presents many potential issues. In this paper, we address the growing prevalence of social networking in education and some of the issues. Next, we use social role theory to explore some pitfalls for educators using social networking. Finally, we suggest that foundational ethical principles from the field of psychology can provide a basis for developing guiding principles for use of social networking in education.  相似文献

This article reports on a study of the awareness, perceptions and use of e-books by academic staff in Further Education (FE) colleges throughout Northern Ireland (NI). It is the first comprehensive study of e-book use by FE faculty in NI and fills a significant gap in the research literature on e-books in education, which has tended to focus on Higher Education and the university setting. Data was collected through an online survey which was distributed to FE faculty across NI. The findings show that although FE academic staff are receptive to e-books and welcome them as a resource, poor reading experience and lack of awareness of relevant titles have had an impact. In particular, the research found that 40% of academic staff, in post less than five years, had not used e-books. Greater availability of titles, promotion, and better integration within teaching and learning emerge as key requisites for effective service delivery and enhancement of e-books within FE, as does the need for better targeted instruction and training aimed at academic staff. Understanding patrons' views, awareness, needs, habits and expectations in relation to e-books is crucial to help direct collection content while budgets remain tight and physical space limited.  相似文献

This article describes a half-day preconference that focused on the library as publisher. It examined how the movement from print to online publication has impacted the roles of libraries and their ability to take on new roles as publishers. The session explored the benefits of libraries becoming publishers, and discussed Open Access, what it is and is not and its importance to libraries and scholarly communication. A detailed case study of the publishing operations of the University Library System at the University of Pittsburgh was presented as an example of a successful library publishing program. The session provided an opportunity for participants to discover ways that libraries can be involved in publishing.  相似文献
