The transitions literature emphasises the role of niches, defined as a protective space for path-breaking innovations. Surprisingly, the concept of protection has not been systematically interrogated. Our analysis identifies effective protection as having three properties in wider transition processes: shielding, nurturing and empowerment. Empowerment is considered the least developed in current niche literature. It can be understood as either processes that make niche innovations competitive within unchanged selection environments (fit-and-conform) or as processes that contribute to changes in mainstream selection environments in ways favourable to a path-breaking niche innovation (stretch-and-transform). Adopting a more constructivist perspective, we subsequently argue that analysis of these properties needs to be complemented with particular attention for the politics involved in their construction. Attention to empowerment confirms the view that niche actors need to link to wider processes of social change, and suggests how this arises. The paper ends with an outlook upon two promising research avenues: (1) the reconstruction of niche development in light of the present framework; (2) analyses of the diverse (political) narratives seeking to empower niches across time and space. 相似文献

If a museum faces a price inelastic demand and twin targets of a minimum number of visits and a minimum revenue, those targets need not be compatible. This paper explores the implications of such targets and shows that their compatibility depends critically on the admission price-elasticity. If the targets are incompatible it may be possible to engineer compatibility by shifting the demand curve. However, if the demand shift (eg resulting from advertising or improving the quality of the visitor experience) requires resourcing and is to be self-financing, it may or may not be possible to bring about compatibility. 相似文献

Governments in Latin America appear to have reached the limits of public subsidy of higher education and they are searching for funding alternatives. Tuition is viewed as one of the means of diversifying support and thereby of reducing the financial pressures on the budgets of these countries. In addition to the economic rationale, advocates of tuition base their arguments on the inequities of public subsidy, on the concept of ‘the ability to pay’, and the need to redirect public subsidy to the elementary and secondary levels. Opposition to tuition is led by the students, with support from faculty and administration in higher education. Opposition is based on the ideology of ‘free’ education, which views higher education as a basic societal obligation and fears the ‘privatization’ of universities if governments do not fulfill their obligations. Tuition is much more than an economic issue and reflects a traditional distrust of government motives within higher education. Without additional sources of funds, however, it is likely that opportunity for higher education will be denied large numbers of students. It is ironic that expansion of opportunity may depend on the implementation of tuition as one method of raising financial support. 相似文献

In 2003, Deakin University implemented a centralised learning management system (LMS) under the banner of Deakin Studies Online (DSO), as well as implementing policies requiring all its units of study to have at least a basic online presence from 2004. Given the scope of the university's commitment to online education, it was considered essential to evaluate the effectiveness of this investment. Based on more than 5400 responses obtained from students in 2004 and 2005 as part of the DSO evaluation survey, the analysis presented here identifies those elements of the online learning environment (OLE) that are most used and valued by students, those elements of the OLE that students most want to see improved, and, those factors that most contribute to students' perceptions that use of the OLE enhanced their learning experience. The most used and valued elements were core LMS functions, including accessing unit information, accessing lecture/tute/lab notes, interacting with unit learning resources, reading online discussions, contacting lecturers/tutors and submitting assignments online. The OLE elements identified as most needing attention were receiving feedback on assignments; viewing my marks; and reviewing unit progress. Students felt that using DSO enhanced their learning experience when they were adequately supported by unit teachers and technical support services; when they were able to find and use unit information; and when they were able to read the online contributions of other unit members. The retrospective analysis of data collected in the period 2004–2005 has been shaped by a forward-looking agenda. The array of elements available within, and in association with, traditional LMSs which has emerged since that time raises the future challenge of how to maximise and evidence educational value through the optimal combination of elements from the portfolio of e-learning technologies increasingly available to educators. 相似文献

Does the discussion help? The impact of a formally assessed online discussion on final student results 总被引:1,自引:0,他引:1

While there is agreement that participation in online asynchronous discussions can enhance student learning, it has also been identified that there is a need to investigate the impact of participation in online discussions on student course performance. This paper presents a case study based on an undergraduate engineering management unit employing a formally assessed online discussion area. It was observed that while many students read a significant number of discussion postings, generally, the posting of new and reply messages occurred at the minimum level required to qualify for the assignment marks. Based on correlation and multiple regression analysis, it was observed that two variables were significantly related to a student's final unit mark—prior academic ability and the number of new postings made to the online discussion. Each new posting contributed three times as much to the final unit mark as its nominal assessment value, suggesting that the work in preparing their new discussion postings assisted students in the completion of a range of assessable tasks for the unit. The number of postings read was not significantly correlated with the final unit mark, suggesting that passive lurking in this online discussion did not significantly contribute to student learning outcomes. 相似文献

Gender differences associated with the development of adolescents' sense of general self-concept (confidence and self-worth) and emotional stability (calmness, freedom from anxiety, and depression) were investigated using a sample of 655 adolescents (mean age 16 years). Relationships with parents were important for males' emotional stability but not females' and so this finding challenges the belief that adolescent males are more concerned with establishing independence from parents than females. The research also challenges the notion that adolescent boys are less interested in close personal peer relationships than girls. Same sex and opposite sex peer relationships were more influential in the formation of adolescents' emotional stability than parental relationships. A reciprocal relationship was revealed between general self-concept and emotional stability. Comparing these results with results obtained on the same students 18 months previously (aged 14.5 years), demonstrates that adolescents increasingly transfer their emotional attachment from parents to peers in a process called individuation. 相似文献

Very little prior research has examined public perceptions of research funding and the life chances associated with various fields of study. In the present task, 315 members of the Austrian general public rated 34 higher-education courses in terms of funding cuts or increases, and the perceived life chances of graduates, respectively. The results showed a high degree of correspondence in the ratings of both questionnaires. Overall, professional and biological stream courses were rated the most favourably, whereas arts and humanities courses were rated the least favourably. Participants’ demographic variables had little influence on their decisions. The implications of these findings for the way higher education is managed and organised are discussed. 相似文献

Positive behavioral interventions and support (PBIS) is a multitiered framework for behavioral support that is being increasingly implemented in schools. Although research has linked PBIS to improved student outcomes, less research is longitudinal and considers both academic and behavioral outcomes. This study examined the relationships between changes in school‐wide (i.e., Tier I) PBIS implementation level and changes in disciplinary and achievement outcomes over a 2‐year period. Participants included 85 Ohio schools with data on PBIS implementation fidelity (from the tiered fidelity inventory, or TFI), out‐of‐school suspensions (OSSs), and statewide achievement tests for the 2015–2016 and 2016–2017 school years. Linear regressions were conducted to examine the degree to which changes in TFI Tier I scores predicted changes in OSS and achievement scores when controlling for school‐level demographic variables that also were related to the outcome variables. Changes in TFI Tier I scores was found to significantly predict changes in OSS per 100 students but not changes in achievement scores. 相似文献
