The Reflective Learning Continuum: Reflecting on Reflection

Abstract: The importance of reflection to marketing educators is increasingly recognized. However, there is a lack of empirical research that considers reflection within the context of both the marketing and...

Growth and Hölder conditions for the sample paths of Feller processes

Abstract: Let (A,D(A)) be the infinitesimal generator of a Feller semigroup such that Cc∞(ℝn)⊂D(A) and A|Cc∞(ℝn) is a pseudo-differential operator with symbol −p(x,ξ) satisfying |p(•,ξ)|∞≤c(1+|ξ|2) and |Imp(x,ξ)|≤c0Rep(x,ξ). We show that the associated Feller process {Xt}t≥0 on ℝn is a semimartingale, even a homogeneous diffusion with jumps (in the sense of [21]), and characterize the limiting behaviour of its trajectories as t→0 and ∞. To this end, we introduce various indices, e.g., β∞x:={λ>0:lim|ξ|→∞|x−y|≤2/|ξ||p(y,ξ)|/|ξ|λ=0} or δ∞x:={λ>0:liminf|ξ|→∞|x−y|≤2/|ξ||e|≤1|p(y,|ξ|e)|/|ξ|λ=0}, and obtain a.s. (ℙx) that lim t→0t−1/λs≤t|Xs−x|=0 or ∞ according to λ>β∞x or λ<δ∞x. Similar statements hold for the limit inferior and superior, and also for t→∞. Our results extend the constant-coefficient (i.e., Levy) case considered by W. Pruitt [27].

Environmental performance and policy regimes: Explaining variations in 18 OECD-countries

Abstract: Although we are witnessing an increasing interest in the comparative study of environmental pollution in the social sciences, there is sharp disagreement over how the state of the environment and the changes in recent decades should be assessed. Furthermore, the debate on environmental policy has no conceptual focus on societal development. Therefore, the article presents, on the one hand, an index of environmental pollution that integrates the levels of pollution in 1990 and their changes in the 1980s, and, on the other hand, an index that incorporates the ideological aspects of social development. Using this distinction it is possible to identify different paths of societal development in 18 OECD countries. The final part of the article explores various structural, economic, institutional and political characteristics which may be used to explain the different outcomes. The results show that institutional factors are important for a successful environmental performance. However, when it comes to change in policy regime the degree of mobilization of ecological movements and parties is essential.
