This paper seeks to bridge the gap between socio-material and complex adaptive systems approaches in conceptualizing the politics of transformation. Our contribution in particular is a further clarification of the relational nature of power, and the role of non-humans in transitional dynamics of complex adaptive systems. We explore and operationalize the role of non-humans and relationality in (1) agency and (2) power, and the implications thereof for processes of (3) powering, through which power relations shape resource distributions and associated macro-scale dynamics. We consider agency as an embedded and temporal capacity for reorientation. This also entails attributing agency to entangled networks of humans and non-humans. Such a capacitive conception of agency follows from our understanding that agents and structures consist of comparable ontological building blocks, both being (networks of) components in complex adaptive systems. Power we understand as a productive and relational phenomenon that emerges from interactions between components and that structures their agency. We argue that such a ‘force-field’ understanding of power enables the observation of different types of power relations. Finally, we consider six different mechanisms through which power relations can result in a (re)distribution of resources and with that, contribute to self-reproducing or transformative systemic dynamics. With this conceptualization, we hope to advance the debate on the different facets of the politics of transformation, and to help further urgently needed transitions towards a more sustainable future. 相似文献

Over time, researchers have acknowledged the importance of understanding the users’ strategies in the design of search systems. However, when involving users in the comparison of search systems, methodological challenges still exist as researchers are pondering on how to handle the variability that human participants bring to the comparisons. This paper present methods for controlling the complexity of user-centered evaluations of search user interfaces through within-subjects designs, balanced task sets, time limitations, pre-formulated queries, cached result pages, and through limiting the users’ access to result documents. Additionally, we will present our experiences in using three measures – search speed, qualified search speed, and immediate accuracy – to facilitate the comparison of different search systems over studies. 相似文献

The present study investigated the role of teacher-rated likeability as a mediator of the relation between low academic competence and depressive symptoms in elementary-aged children. Analyses focused on a sample of children at risk for child maltreatment living in Hawaii (n = 380). Structural equation modeling supported the hypothesized negative relations between academic competence in first grade and depressive symptoms in third grade controlling for correlated constructs (e.g., baseline social avoidance, parenting stress, externalizing problems, and internalizing symptoms). Teacher-rated likeability in second grade negatively mediated the effect of academic competence on depressive symptoms. Implications for understanding the role of early academic skill deficits and social judgments on risk for depressive symptoms as well as recommendations for interventions and prevention strategies are discussed. 相似文献

Members of the Somerset Inclusion Project and Gary Thomas (professor and reader in education at the University of the West of England, Bristol) discuss the need for schools to become more inclusive in response to the Government's recent Green Paper (DfEE, 1997), which emphasises that special schools need to work in different ways and to provide services to local mainstream schools. The notion that inclusion is right and segregation is wrong led the staff to convert the Princess Margaret School (PMS) in Taunton, Somerset to an inclusion service. 相似文献

The Medical School Learning Environment Survey (MSLES) was used with a sample of 311 undergraduate medical students in British Columbia, Canada, to assess the seven scales of Medical Breadth of Interest, Personal Breadth of Interest, Emotional Climate, Flexibility, Meaningful Learning Experience, Organization, Nurturance and Student–Student Interaction. Confirmatory factor analysis was used to support the validity of the MSLES when used with this sample. 相似文献
