In this article, we consider the formation of responsible research relationships with Inuit communities from an “outsider” researcher perspective. Cautious not to prescribe what counts as responsible, we draw on research experiences in several Nunavut communities to introduce and explain “engaged acclimatization.” This neologism refers to embodied and relational methodological processes for fostering responsible research partnerships, and is inspired by the significance of preliminary fieldwork in orienting the lead author's doctoral thesis. As a complement to community‐based participatory methodologies, engaged acclimatization facilitates endogenous research by enacting ethics as a lived experience, initiating and nurturing relationships as a central component of research, and centring methods on circumstances within participating communities. After we locate engaged acclimatization within resonant literature and details of interrelated research projects, our article sketches out four aspects of engaged acclimatization: crafting relations, learning, immersion, and activism. In our discussion of each, we integrate specific insights derived from field notes, observations, photographs, critical reflections, and literature that have brought us to this understanding. The four aspects provide conceptual and methodological tools for readers to apply in the contexts of their own research programs or in guidelines for establishing partnerships with Inuit or Aboriginal communities. The value of this article lies in the extent to which it encourages readers to situate engaged acclimatization in their own research and further develop it as a process.  相似文献

In this introduction to the Policy Study Journal's special issue on punctuated equilibrium, we provide an overview of the approach, how it evolved, some of the major critiques directed at it, and some of the major developments it has spawned. We argue that the most important aspect of a theory or framework is not whether it is right or wrong, but the extent to which it is fruitful; that is, the extent to which it stimulated further research. Finally, we review the articles in this issue and put them in context.  相似文献

Hub-and-Spoke Networks in Air Transportation: An Analytical Review   总被引:16,自引:0,他引:16  
In this review we survey advances in analysis of the hub location problem and its variants. In the course of the review opportunities for enhanced analysis become apparent. We emphasize the most pressing areas for further work. We found that first, research needs to be devoted to developing more reliable heuristics for the multiple assignment model and its extensions and second, that additional research is needed to understand the conditions under which the model will tend to have integer solutions. Research in this area will contribute to the solution of a longstanding puzzle in economics about the allocation of indivisible resources.  相似文献

Although a tremendous amount of analytical research is being conducted on the hub location problem, few models exist that extend the number of characteristics found in actual hub-and-spoke networks. Four extensions are presented in this paper: (1) a capacitated network model; (2) a minimum threshold model; (3) a model that endogenously determines the number of open hubs for the network; and (4) a model that incorporates a flow-dependent cost function for the spokes as well as the interhub links. Both the capacitated and the minimum threshold models drop the assumption of a completely interconnected network commonly found in hub location models. Numerical results show that total network costs are often minimized by closing a few interhub links. The third extension is the first known hub location model to determine the optimal number of hubs based on the needs of the network. In this model, the number of open hubs depends on the distribution of flows in the network and how cost effectively the flows can be moved across the network. Previous models that endogenously determined the number of open hubs utilized a fixed cost for establishing each hub in order to limit the number of hubs in the network. The final extension recognizes the potential of all links to amalgamate flows and includes a separate flow-dependent cost function for the spokes in addition to the one for the interhub links. Numerical results are shown for all four models.  相似文献
