Modulus and Poincaré Inequalities on Non-Self-Similar Sierpiński Carpets

A carpet is a metric space homeomorphic to the Sierpiński carpet. We characterize, within a certain class of examples, non-self-similar carpets supporting curve families of nontrivial modulus and supporting Poincaré inequalities. Our results yield new examples of compact doubling metric measure spaces supporting Poincaré inequalities: these examples have no manifold points, yet embed isometrically as subsets of Euclidean space.

Small town sustainability: economic, social, and environmental innovation. 2. überarb. Aufl.

In an age where the globalization process is threatening the uniqueness and vitality of small towns, and where most urban planning discourse is directed at topics such as metropol-regions or mega-regions and world cities, the authors here emphasize the need to critically reflect on the potential of small towns. The second edition is expanded to cover the intensive development of small towns in China and Korea. In addition, the authors examine the impact of the economic crisis on small towns and the recent development of the Slow City movement.

Quantitative 3D strain analysis in analogue experiments: Integration of X-ray computed tomography and digital volume correlation techniques

The combination of scaled analogue experiments, material mechanics, X-ray computed tomography (XRCT) and Digital Volume Correlation techniques (DVC) is a powerful new tool not only to examine the 3 dimensional structure and kinematic evolution of complex deformation structures in scaled analogue experiments, but also to fully quantify their spatial strain distribution and complete strain history. Digital image correlation (DIC) is an important advance in quantitative physical modelling and helps to understand non-linear deformation processes. Optical non-intrusive (DIC) techniques enable the quantification of localised and distributed deformation in analogue experiments based either on images taken through transparent sidewalls (2D DIC) or on surface views (3D DIC). X-ray computed tomography (XRCT) analysis permits the non-destructive visualisation of the internal structure and kinematic evolution of scaled analogue experiments simulating tectonic evolution of complex geological structures. The combination of XRCT sectional image data of analogue experiments with 2D DIC only allows quantification of 2D displacement and strain components in section direction. This completely omits the potential of CT experiments for full 3D strain analysis of complex, non-cylindrical deformation structures. In this study, we apply digital volume correlation (DVC) techniques on XRCT scan data of “solid” analogue experiments to fully quantify the internal displacement and strain in 3 dimensions over time. Our first results indicate that the application of DVC techniques on XRCT volume data can successfully be used to quantify the 3D spatial and temporal strain patterns inside analogue experiments. We demonstrate the potential of combining DVC techniques and XRCT volume imaging for 3D strain analysis of a contractional experiment simulating the development of a non-cylindrical pop-up structure. Furthermore, we discuss various options for optimisation of granular materials, pattern generation, and data acquisition for increased resolution and accuracy of the strain results. Three-dimensional strain analysis of analogue models is of particular interest for geological and seismic interpretations of complex, non-cylindrical geological structures. The volume strain data enable the analysis of the large-scale and small-scale strain history of geological structures.

Social and cognitive predictors of fruit and vegetable intake among adolescents: The context of changes in body weight

Two studies investigated differences in the relationships between adolescents' fruit and vegetable intake (FVI) and the predictors specified in the Health Action Process Approach and Social-Cognitive Theory. Retrospective (Study 1; N = 502) and prospective (Study 2; N = 668) designs were applied. Among adolescents with overweight/obesity, intention was cross-sectionally associated with FVI (Study 1); no social or cognitive predictors explained FVI at 14-month follow-up (Study 2). The planning - FVI and self-efficacy - FVI relationships were stronger among adolescents who reduced their body weight to normal, compared to effects observed among those who maintained their body weight (Studies 1 and 2).

Copying, emergence, and digital reproduction

This talk combines concepts of the copying of manuscripts in the age before mechanical reproduction (as described in W. Benjamin’s famous Artwork-essay), of the emergence of non-vertical evolution (as to be found in textual ‘contamination’ and in horizontal gene transfer alike), and of the electronic reproduction of such phenomena (as presented in scholarly digital editions and phylogenetic trees). The guiding idea is that ‘copying’, ‘emergence’, and ‘(digital) reproduction’ enable variation depending on particular physical or biological forms, on contextual or environmental conditions, as well as on user habits or receptive fields. – Is it possible to develop a theory of copying and reproduction on this base? The material of the talk will be drawn from the Parzival-Project, a critical electronic edition of an Arthurian romance, composed by the German poet Wolfram von Eschenbach shortly after 1200 and transmitted in over eighty witnesses.

Widows may have fewer social and financial problems than in the past (Interview von Shereen Lehman mit Prof. Pasqualina Perrig-Chiello zu finanziellen und sozialen Problemen von Verwitweten)

(Reuters Health) – - A new Swiss study says that widows and widowers still mourn their spouses as much as ever, but compared to 35 years ago, everyday life is easier, especially for women. Widows, at least in Switzerland, have fewer financial troubles and more social connections than their counterparts in 1979, but widowers still complain of loneliness, researchers found.

Performing ‘Readings’: The Interplay of Theatre And Digital Comics In Tezuka

The article investigates the intriguing interplay of digital comics and live-action elements in a detailed performance analysis of TeZukA (2011) by choreographer Sidi Larbi Cherkaoui. This dance theatre production enacts the life story of Osamu Tezuka and some of his famous manga characters, interweaving performers and musicians with large-scale projections of the mangaka’s digitised comics. During the show, the dancers perform different ‘readings’ of the projected manga imagery: e.g. they swipe panels as if using portable touchscreen displays, move synchronously to animated speed lines, and create the illusion of being drawn into the stories depicted on the screen. The main argument is that TeZukA makes visible, demonstrates and reflects upon different ways of delivering, reading and interacting with digital comics. In order to verify this argument, the paper uses ideas developed in comics and theatre studies to draw more specifically on the use of digital comics in this particular performance.
