Resumo: As divisões do mundo pautadas por marcos culturais têm uma longa tradição na geografia germanófona. Até os dias de hoje, a cultura é conceitualizada como totalidade, o que leva conseqüentemente a que cada divisão absolutize as diferenças culturais. O artigo descreve esta problemática com base nos conceitos clássicos desde os primórdios da geografia até a geografia do presente. Também para a discussão atual pode-se constatar que a idéia de um conceito holístico de cultura ainda permanece usual e até agora não foi substituída por uma regionalização alternativa. O artigo conclui com uma sugestão de como esta regionalização alternativa poderia ser na era da globalização. Culture as holism: large-scale classification of the world in German-speaking geography Abstract: Divisions of the world using culture as the defining trait have had a long history in German geography. Until this day, culture is being conceptionalized as a whole, with the consequence that each division poses cultural differences as absolutes. This essay aims to describe the problem by using traditional concepts from the beginning of geography up to the present. Even in the current debate, as will be shown, the idea of a holistic concept of culture is still in use and has not been replaced yet by an alternative form of regionalisation. The article will conclude with a suggestion of what this would look like in the age of globalisation. Keywords: Culture, division of the world, holism, globalisation, German classics

SummaryIon channel models are the building blocks of computational neuron models. Their biological fidelity is therefore crucial for the interpretability of simulations. However, the number of published models, and the lack of standardization, make the comparison of models with one another and with experimental data difficult. Here, we present a framework for the automated large-scale classification of ion channel models. Using annotated metadata and model responses to a set of voltage-clamp protocols, we assigned 2378 models of voltage- and calcium-gated ion channels coded in NEURON to 211 clusters. The IonChannelGenealogy web interface provides an interactive resource for the categorization of new and existing models and experimental recordings. It enables quantitative comparisons of simulated and/or measured ion channel kinetics, and facilitates field-wide standardization of experimentally-constrained modeling.
