In search of systemic innovation for sustainable development: A design praxis emerging from a decade of social learning inquiry

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.     

Beyond Useful Knowledge: Developing the Subjective Self

While not underestimating the value of useful knowledge and skills, it is suggested that education should also develop the subjective self of the learner. A distinction is drawn between an ‘additive’ view of education which simply furnishes the individual with knowledge and skills and a ‘transformative’ concept which concerns itself with changes to more central parts of the learner's self. In developing a concept of the subjective self, reference is made to the Enlightenment notion of the autonomous rational self and the interpersonal or cultural self of the Symbolic Interactionists and Communitarians. Particular attention, however, is given to Heidegger's three categories of entities experienced by the phenomenological self: the ‘present at hand’, the ‘ready to hand’ and those entities with whom we share the experience of ‘being with’. An attempt is made to interpret important aspects of education in terms of the development of learners' growing knowledge and deepening understanding of these three kinds of entity and the relation in which they stand to them.     

Effect of time of day on perceived exertion at work rates above and below the ventilatory threshold

The effect of time of day on ratings of perceived exertion (RPE) at various intensities of cycling exercise, both below and above the ventilatory threshold, was studied in 32 subjects, 18 to 35 years of age. The ventilatory threshold occurred at the same (p greater than .05) mean (+/- SD) work rate in the morning (110.6 +/- 27.0 watts) and in the afternoon (111.9 +/- 23.9 watts) and was perceived as equally strenuous (p greater than .05) in the morning (RPE = 13.8 +/- 2.4) and in the afternoon (RPE = 13.6 +/- 2.8). At intensities below the ventilatory threshold, RPE was the same (p greater than .05) in the morning and in the afternoon; above the ventilatory threshold, RPE was lower (p less than .05) in the morning. We conclude that, during incremental submaximal cycling exercise above the ventilatory threshold, a particular work rate is perceived as less strenuous in the morning than in the afternoon. About 20% of this difference in RPE is explained by lower ventilatory demands in the morning.
