This article addresses the important questions that higher education institutions ask concerning their impact on their students’ sustainability-related attributes ‘How do our students’ worldviews change as they experience higher education with us?’ The process of monitoring such a dynamic entity is fraught with statistical complexity but may not be impossible for an institution willing to ask whether or not its educational efforts in ‘education for sustainability’, ‘education for sustainable development’ or ‘environmental education’, and campus sustainability developments, are paralleled by changes in the attitudes of its students. We describe here a longitudinal survey process based on the revised New Ecological Paradigm scale, with two cohorts of students, in three programmes of study, operating over four years, with multiple survey inputs by each student. We implemented the longitudinal analysis using a linear mixed-effects model and describe here the development and testing of this model. We conclude that higher education institutions can benchmark the sustainability attributes of their students and monitor changes, if they are minded to. We invite higher education practitioners worldwide to join us in further developing suitable research instruments, processes and statistical models, and in further analysing the assumptions that link higher education to sustainability and to global citizenship. 相似文献

Recent controversies surrounding privacy have sparked a move by regulators toward the idea of privacy by design (PbD), a concept pioneered by Ontario Information and Privacy Commissioner Ann Cavoukian. Industry has also started to recognize the importance of taking privacy seriously, with various PbD corporate initiatives currently underway. However, some commentators have criticized PbD for being too vague. Using three case studies and a range of best practice examples of PbD, privacy impact assessments (PIAs), and privacy-enhancing technologies (PETs), this article addresses the gap between the abstract principles of PbD and their operationalization into more concrete implementation guidelines for software engineers. 相似文献

Creating value in ecosystems: Crossing the chasm between knowledge and business ecosystems 总被引:1,自引:0,他引:1
Policy makers take initiatives to stimulate knowledge ecosystems in technology hotspots. It is implicitly assumed that these ecosystems will lead to value networks through which the participating companies can realize a competitive advantage. Value networks refer to business ecosystems where the value proposition is offered by a group of companies which are mutually complementary. The strategy literature suggests that business ecosystems lead to competitive advantages for each of the partners in the ecosystem. Based on a unique hand-collected database of 138 innovative start-ups in the region of Flanders, we analyze the knowledge and business ecosystem and the financial support network. We find that the knowledge ecosystem is well structured and concentrated around a number of central actors while the business ecosystem is almost non-existent at the local level. Further, we find that the financial support network is almost 100% publicly backed and fails to bridge the knowledge and business ecosystem. The implications for policy makers who tend to focus on the development of local ecosystems are discussed. 相似文献

OBJECTIVE: This study compares homeless women who had childhood histories of foster care or other out-of-home placement to those who have not. METHOD: A countywide probability sample of homeless women (n = 179) received structured interviews. RESULTS: One-third of homeless women reported being raised apart from their parents. Among women with children under age 18, most (61.5%) had children who had lived in foster care or other out-of-home placements. Variables associated with homeless mothers' children living in foster care or other out-of-home placements were: Child was school-age, mother was age 35 or older, mother had a current alcohol or drug use disorder, mother experienced childhood sexual abuse, and mother ran away from home (when under age 18). CONCLUSIONS: Parenting is difficult for homeless mothers who may need to place their children with others to facilitate school attendance. Parent-child interaction may be problematic in family shelters where privacy is rare. Thus, programs promoting family preservation for homeless mothers should provide parenting support as well as permanent housing. 相似文献

Jannet A. Wright and Myra Kersner, senior lecturers in the Department of Human Communication Science, University College London, consider the practical implications of recent policies for teachers and speech and language therapists working together in inclusive settings. Their conclusions complement McCartney's ideas in the previous article. 相似文献

Caroline Coles, Headteacher of Horton Lodge School in Staffordshire, and Liz Zsargo, Lecturer in Conductive Education at Keele University, consider the development of Conductive Education (CE) in the UK, and place it in the context of some of the sociological analyses of disability. They argue that CE can provide the basis for an educational model of disability (in which disability is seen as a result of a complex interaction between the environment and the individual), that all children have the right to an education suitable for their needs, and that a lack of access to an appropriate education can be a disabling factor. 相似文献
