What Might Have Been Lost

This article examines the role of “independent” folk music (indie-folk) in personal identity formation. It builds upon Paul Ricoeur’s theory of narrative identity, which argues (i) that it is through the mechanism of narrative that people build a more or less coherent life-story, and (ii) emphasizes the role of art (most notably literary fiction and poetry) as a mediator in the comprehension and regulation of transitory life experiences. This article aims to apply these insights to studying the role of indie-folk, a narrative art form adhering to the traditional understanding of folk music as a genre rooted in oral tradition, in the construction of personal identity. Studying the daily use of indie-folk songs by audience members through in-depth interviewing, it shows that (i) the reception of indie-folk music results in ritualistic listening behavior aimed at coping with the experience of accelerating social time; (ii) that respondents use indie-folk narratives as resources for reading the self, and (iii) that indie-folk songs provide healing images that are effective in coping with the experience of narrated time as discordant. In arguing for the central role of narrative in identity formation, this article aims to contribute to existing research on music as a “technology of the self” (DeNora). It specifically emphasizes how narrative particles are tools and building blocks in identity construction, a process characterized by the oscillation between narrative coherence and disruption

Benefits of protected areas for nonbreeding waterbirds adjusting their distributions under climate warming

Climate warming is driving changes in species distributions and community composition. Many species have a so-called climatic debt, that is, shifts in range lag behind shifts in temperature isoclines. Inside protected areas (PAs), community changes in response to climate warming can be facilitated by greater colonization rates by warm-dwelling species, but also mitigated by lowering extirpation rates of cold-dwelling species. An evaluation of the relative importance of colonization-extirpation processes is important to inform conservation strategies that aim for both climate debt reduction and species conservation. We assessed the colonization-extirpation dynamics involved in community changes in response to climate inside and outside PAs. To do so, we used 25 years of occurrence data of nonbreeding waterbirds in the western Palearctic (97 species, 7071 sites, 39 countries, 1993-2017). We used a community temperature index (CTI) framework based on species thermal affinities to investigate species turnover induced by temperature increase. We determined whether thermal community adjustment was associated with colonization by warm-dwelling species or extirpation of cold-dwelling species by modeling change in standard deviation of the CTI (CTISD). Using linear mixed-effects models, we investigated whether communities in PAs had lower climatic debt and different patterns of community change than communities outside PAs. For CTI and CTISD combined, communities inside PAs had more species, higher colonization, lower extirpation, and lower climatic debt (16%) than communities outside PAs. Thus, our results suggest that PAs facilitate 2 independent processes that shape community dynamics and maintain biodiversity. The community adjustment was, however, not sufficiently fast to keep pace with the large temperature increases in the central and northeastern western Palearctic. Our results underline the potential of combining CTI and CTISD metrics to improve understanding of the colonization-extirpation patterns driven by climate warming

Virtual Building Lifecycle - Giving architects access to the future of buildings by visualizing lifecycle data

Today's software for architects and civil engineers is lacking support for the evaluation and improvement of building lifecycles. Facility Management Systems and 4D-CAD try to integrate lifecycle data and make them better accessible, but miss the investigation of the development of the structure itself. Much money is inappropriately spent when materials with different life expectancies are combined in the wrong way and building parts are repaired or replaced too early or too late. With the methods of scientific visualization and real-time 3Dgraphics these deficiencies can be eliminated. The project “Virtual Building Lifecycle” (short VBLC, [W-VBLC]) connects 3D geometrical information to research data such as life expectancy and emissions and to standard database information like prices. The automated visualization of critical points of the structure in the past, presence and future is a huge advantage and helps engineers to improve the duration of the lifecycle and reduce the costs

KAMEDIN: a telemedicine system for computer supported cooperative work and remote image analysis in radiology

The siftware systen JAMEDIN (Kooperatives Arbeiten und MEdizinische Diagnostik auf Innovativen Netzen) is a multimedia telemedicine system for exchange, cooperative diagnostics, and remote analysis of digital medical image data. It provides components for visualisation, processing, and sychronised audio-visual discussion of medical images. Techniques of computer supported cooperative work (CSCW) synchronise user interactions during a teleconference. Vsisibility of both local and remote cursor on the conference workstations facilitates telepointing and reinforces the conference partner's telepresence. Audio communication during teleconferences is supported by an integrated audio component. Furthermore, brain tissue segmentation with artificaial neural networks can be performed on an external supercomputer as a remote image analysis procedure. KAMEDIN is designed as a low cost CSCW tool for ISDN based telecommunication. However it can be used on any TCP/IP supporting network. In a field test, KAMEDIN was installed in 15 clinics and medical departments to validate the systems' usability. The telemedicine system KAMEDIN has been developed, tested, and evaluated within a research project sponsored by German Telekom
