Processes of designing for systemic innovation for sustainable development (SD) through the lens of three long-term case studies are reported. All case studies, which originated from the SLIM (Social Learning for the Integrated Management and Sustainable Use of Water at Catchment Scale) Project, funded within the EU Fifth Framework Program (2001–2004), constitute inquiry pathways that are explored using a critical incident approach. The initial starting conditions for each inquiry pathway are compared; significant pathway dependencies are identified which foster the development of social learning processes locally, but constrain their uptake and embedding across the wider system of interest. In the first case study, in England & Wales, promising developments in the application of social learning approaches to river basin planning over an initial 3-year period were subsequently marginalised, only to resurface towards the end of the 10-year period of study. In the second, South African case study, significant spaces for social learning and innovation in integrated water resources management were opened up over a five year period but closed down again, primarily as the result of lack of policy support by national government. The third, Italian, case study was designed to assess options for adapting to climate change by opening up new learning spaces between researchers, stakeholders and policy makers. A case for investing in local level systemic innovation through social-learning praxis design approaches and in learning processes around well contextualised case-studies is supported. However, concomitant investment by policy makers in social learning as an alternative, but complementary, governance mechanism for systemic innovation for SD is needed.  相似文献

Knowledge spillover occurs when recipient firms combine the knowledge of an originating firm with other knowledge. When recipient firms combine the originating firm's knowledge with knowledge that is unfamiliar to the originating firm, the recipient firms potentially provide insight to the originating firm on the viability of exploring such knowledge. By mimicking its recipient firms, the originating firm reduces the challenge and uncertainty of exploring unfamiliar knowledge domains. We examine the exploration activities of 87 telecommunications equipment manufacturers over a ten-year time period. We argue that those firms that operate in competitive and dynamic market environments promoting conservative risk-taking behavior will value such uncertainty reduction more highly and thus rely to a greater extent on their recipient firms for guidance on where to explore for new expertise. In contrast, firms in high-growth market environments are more likely to look beyond the activities of recipient firms when exploring new technological domains and rely less on mimicking their recipient firms.  相似文献

Recent simulations by Chen and Dorfman [Electrophoresis 35, 405–411 (2014)] suggested that “tilting” the electric field with respect to the lattice vectors of a hexagonal post array would lead to a substantial improvement in electrophoretic DNA separations therein. We constructed such an array where the electric field is applied at an angle equidistant between the two lattice vectors. This tilted array leads to (i) baseline resolution of 20 kbp DNA and λ DNA (48.5 kbp) in a 4 mm channel and (ii) measurable separation resolutions for electric fields up to 50 V/cm, both of which are improvements over untilted post arrays of the same post density. The predicted time required to reach a resolution of unity is approximately 5 min, independent of electric field. The separations are more reproducible at higher fields.  相似文献

Numerous studies have confirmed direct health effects of interventions with a physical activity component on students without providing sufficient information on the contents or the degree to which the programs have been carried out. The empirical evidence of the indirect health effects of physical education is weaker. In this article the focus is placed on the evaluation of the indirect health effects, such as the enhancement of physical activity and its psychological determinants (e.g. motivation, attitudes, self-efficacy and knowledge) of the health promotion program HealthyPEP, using a quasi-experimental design with 516 sixth grade students. When taking into account the contents of HealthyPEP and the degree of implementation, it was clear that the program had different effects on the two genders whereby girls evaluated HealthyPEP in a more positive way compared to boys. In girls, positive tendencies were observed on rational cognitive determinants (e.g. knowledge and attitudes towards sports). The contents of HealthyPEP must be further optimized in the future to achieve positive indirect health effects also on boys.  相似文献

Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2‐year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but not changes therein, and was not associated with fluid ability. Furthermore, IE predicted change in school grades in language but not in mathematics grades or in standardized tests. These findings suggest that IE is not a major predictor of knowledge acquisition in adolescence, where degree of self‐determination in intellectual behaviors may be relatively limited. Open questions for future research are addressed, including reciprocal longitudinal associations between IE and academic and cognitive development.  相似文献

Fungi are non-chlorophyllus microorganisms, which constitutes the main source of outdoor and indoor allergens. The antigens present in the spores and fragments of hyphae induce allergic responses in sensitized patients. The frequently recognized fungi associated with asthma include Alternaria, Cladosporium, Aspergillus, and Penicillium. With the advent of molecular biology techniques a number of fungal genes encoding relevant allergens have been cloned and the expressed allergens purified and characterized. In this review, we have presented the recent developments, where recombinant allergens have been used in the precise diagnosis of fungal allergy. We have also discussed the role played by these allergens and the T- and B-cell epitopes in the immune mechanism in fungal allergy.  相似文献

This paper attempts to apply historical methods to help understand the relationship between the philosophy espoused in the works of Laozi or Tao De Ching and educational leadership. The objective is to study the thought of Laozi regarding leadership, to identify ideas and solutions that can be applied in modern educational management, as well as to provide a new definition and values to the ideas of Laozi. Laozi lived in ancient times, meaning that the works describing his thought are difficult to understand. The present study is primarily based on English sources written on Laozi by Ju-Chou Yang and on the commentary on Laozi by Bi Wang. Additionally, this article also refers to and compares other comments on the ideas of Laozi regarding management. This study finds that Laozi had varied ideas on management and philosophy. Laozi ’s views regarding organization are still relevant today. He stressed flexibility and the importance of adapting to the environment. As regards leadership, Laozi emphasized non-action, softness, humility, calmness and the elimination of desire. Furthermore, in his art of employment, Laozi insisted that leaders must overcome their personal likes and dislikes in relation to individuals to ensure the full utilization of their potential.  相似文献

Lesbian, gay, bisexual, transgender, and questioning or queer (LGBTQ) students at evangelical Christian colleges are a population frequently overlooked in the literature on the spiritual lives of college students. The author used qualitative content analysis within a phenomenological tradition to examine blog posts by such students, who face multiple identity challenges and official sanctions on campuses. Findings indicate these students want to be recognized as both LGBTQ and evangelical Christian by their colleges. Included are implications for counseling professionals and college administrators.  相似文献

Access arrangements are the way in which awarding bodies for public examinations in England, such as the General Certificate of Secondary Education, make reasonable adjustments for students with special educational needs and disabilities. SENCos have expressed concerns about the onerous nature of managing requirements for access arrangements, both administratively and practically, but there has been little explanation of why an apparently straightforward process proves so challenging. In this study, the development of a whole-school system to improve the administrative and practical management of access arrangements is used to seek to understand how the requirements set (and re-set) annually interact with school systems and processes to render the administration of access arrangements potentially complex, time-consuming and unpredictable. Scotland's flexible, school-led framework of requirements for the management of public examination assessment arrangements is highlighted as potentially more fit-for-purpose for the organisation of statutory reasonable adjustments for educational assessment.  相似文献
