Nonlinear Multivariate Spatial Modeling Using NLPCA and Pair‐Copulas

A novel geostatistical modeling approach is developed to model nonlinear multivariate spatial dependence using nonlinear principal component analysis (NLPCA) and pair‐copulas. In spatial studies, multivariate measurements are frequently collected at each location. The dependence between such measurements can be complex. In this article, a multivariate geostatistical model is developed that can capture both nonlinear spatial dependence across locations and nonlinear dependence between measurements at a particular location. Nonlinear multivariate dependence between spatial variables is removed using NLPCA. Subsequently, a pair‐copula based model is fitted to each transformed variable to model the univariate nonlinear spatial dependencies. NLPCA and pair‐copulas, within the proposed model, are compared with stepwise conditional transformation (SCT) and conventional kriging. The results show that, for the two case studies presented, the proposed model that utilizes NLPCA and pair‐copulas reproduces nonlinear multivariate structures and univariate distributions better than existing methods based on SCT and kriging.     

Wicked game of smart specialization: a player’s handbook

The objective of this article is to explore the theoretical foundations of a wicked game. The theoretical part is based on the notion of wicked problems, which is developed further. It is also illustrated that the latest innovation strategy of the European Union, called smart specialization, resembles a wicked game. Comparison between the two revealed several similarities gives new insights into the theory of wicked problems and into the process of smart specialization.     

Wandering intellectuals: establishing a research agenda on gender,walking, and thinking

Building on a study of three women who practice walking-for-thinking as a part of their intellectual work, the analysis identifies potential themes for a future research agenda on gender, walking, and thinking. A particular focus is the subtle, daily, management of gendered expectations and ways in which walking, for these women, is a contribution to such management. We name this ‘walking away from expectations’ and identify three themes: walking away from others’ gaze, walking away from restlessness and domestic responsibility, and walking away as belonging. Walking emerges as a skilful way of creating the conditions to do one’s intellectual work and manage gendered expectations. Further, the meanings of silences about gender in the context of intellectual work and walking is discussed and questions for future research agenda are suggested.     

‘Musicking’ children from the Bohemian lands: nurtured and hidden musical practices on both sides of the Iron Curtain

Based on an analysis of musical childhood memories from over 80 Germans from the Bohemian lands and historical evidence, this article investigates processes of social and political integration and assimilation of German children and young adults who, in the aftermath of the Second World War, were either expelled to Germany or remained in their Bohemian homelands. Memories of Germans expelled to West Germany disclose the various ways in which musical repertoire and musical practices are able to mitigate both the loss of the homeland and the distressing overall effects of expulsion, as well as reveal how music facilitates the building of a new sense of belonging in the face of geographic displacement and material dispossession. The study further highlights how the reframing and even silencing of musical practices on the other side of the Iron Curtain in Czechoslovakia affected processes of social-identity reconstruction until and after the 1989 fall of Communism. Results of this study foreground that individual musical experiences reveal new historical narratives of how German expellees used and still use musical practices to negotiate intercultural power relationships and rebuild a sense of belonging in their respective post-war environment in West Germany or Czechoslovakia/Czech Republic.
