The Aesthetic Motives in the Philosophical Anthropology of Arnold Gehlen
No full textThe author of the article reconstructs the aesthetic motives in Arnold Gehlen’s project of philosophical anthropology. The first part of the essay presents the process of emerging of artistic creativity from ritual-presenting actions. In the second part author elaborates the conception of abstract art, which Gehlen treats as a specific laboratory in which artists explore the possibilities of deep, previously undiscovered layers of human perception.The author of the article reconstructs the aesthetic motives in Arnold Gehlen’s project of philosophical anthropology.

Reflections around the idea of man as a deficient being: Ortega, Gehlen and Sloterdijk
No full textEn este artículo se realiza un recorrido a la concepción del hombre
como ser carencial, una idea presente en la tradición filosófica desde Platón
pero que tuvo un importante repunte entre los siglos XIX y XX en el contexto
del surgimiento en Alemania de la antropología filosófica. En primer lugar,
expondremos la apropiación de esta concepción del ser humano como ser deficitario
en Ortega y Gehlen, para pasar, en segundo lugar, a su crítica por parte
de Sloterdijk. Acabaremos con una propuesta en la que se armonizan estas
reflexiones con los últimos datos aportados por la ciencia paleoantropológica.In this paper we carry out a review to the notion of man as a deficient
being, an idea that can be located back in Plato, but one that had an important
upsurge in the 19th and 20th centuries in the context of the emergency in Germany
of the Philosophical Anthropology. In the first place, we will expose the
interpretation of this notion by Ortega and Gehlen, to then turn, in the second
place, to Sloterdijk´s critique of this idea. We will finish with a proposal that
harmonizes this reflections with the last data provided by paleoanthropology
Totemismo e raffigurazione imitativa. Su alcuni aspetti della “teoria delle istituzioni” di Arnold Gehlen
No full textDalla duplice via della ricostruzione interna alla sua opera e del raffronto su singoli aspetti con pensatori come Hans Blumenberg, Claude Lévi-Strauss, Jürgen Habermas, Helmut Schelsky o René Girard, emerge la rilevanza del plesso tematico della mimesis nel pensiero di Arnold Gehlen. Oltre al peso nella costituzione del legame sociale, in termini genetici e in termini di sostegno permanente (insieme alla relativa distinzione tra imitazione diretta e mediata), l’imitazione ha mostrato di svolgere un ruolo decisivo sia nello sviluppo infantile e nell’apprendimento (ontogenesi) sia nel processo di ominazione attraverso la raffigurazione imitativa, l’oggettivazione e il trasporsi in altro del totemismo e il sorgere delle istituzioni (filogenesi). All’imitazione fanno poi capo una serie di lemmi e snodi descrittivi o concettuali legati al comportamento raffigurativo (la scansione e la danza ritmiche e mimiche, il comportamento responsivo, la raffigurazione mimica “in vivo” e “in materia”, l’imitazione reciproca tra i membri di un gruppo e l’imitazione di qualcosa di esterno al gruppo stesso, il contagio sociale, il carattere linguistico-espressivo dell’azione ritmica stilizzata, la raffigurazione in immagine e il rito davanti all’immagine di culto, la configurazione culturale dei principi vitali, l’identificazione e la differenziazione di sé e altro, la metamorfosi che ne consegue e la rende possibile) che sconsigliano di assumere la nozione di imitazione come pura costruzione provvisoria, per quanto fondamentale, da ritenersi superata nello sviluppo della storia umana, e ne fanno una connotazione permanente, una sorta di costante antropologica nella visione gehleniana, che svolge una funzione non surrogabile nel sostegno delle “finzioni istituzionali” e delle formazioni simboliche. Tutti motivi che portano non solo a raccomandare la portata euristica del “totem” e della “caverna” gehleniani per la discussione di una gamma di problemi della teoria sociale, della filosofia politica, e della riflessione filosofica e morale tout court, che va – come pure si è visto – dal rapporto tra concetti e immagini, alle istituzioni del senso, alle forme simbolico-espressive della raffigurazione e della ritualità nella sfera pubblica, alle ragioni della potenza dell’impotenza, fino alla concezione dell’uomo e dei rapporti tra natura e storia, ma anche, richiamando infine l’angolo visuale più specifico che ha orientato l’intera esposizione, alla ridefinizione del campo di interesse per la mimesis

Epoxy-coated reinforcement in concrete structures: results of a Swiss pilot project after 24 years of field exposure
No full textReinforced concrete is the most common construction material of civil infrastructure. In severe environment, e.g. chloride exposure, concrete deterioration can occur with consequences on the durability of the structure. The use of epoxy-coated reinforcement is a strategy to control chloride induced reinforcement corrosion, particular by prolonging the initiation and propagation phase. The epoxy-coating acts as a physical barrier to chlorides and the electrolyte concrete. However, the effectiveness of the strategy in chloride environment and the corrosion performance of ECR in presence of coating defects is investigated by condition assessment of a Swiss pilot project after 24 years of field exposure
Projected pH reductions by 2100 might put deep North Atlantic biodiversity at risk
No full textThis study aims to evaluate the potential for impacts of ocean acidification on North Atlantic deep-sea ecosystems in response to IPCC AR5 Representative Concentration Pathways (RCPs). Deep-sea biota is likely highly vulnerable to changes in seawater chemistry and sensitive to moderate excursions in pH. Here we show, from seven fully coupled Earth system models, that for three out of four RCPs over 17% of the seafloor area below 500 m depth in the North Atlantic sector will experience pH reductions exceeding −0.2 units by 2100. Increased stratification in response to climate change partially alleviates the impact of ocean acidification on deep benthic environments. We report on major pH reductions over the deep North Atlantic seafloor (depth >500 m) and at important deep-sea features, such as seamounts and canyons. By 2100, and under the high CO2 scenario RCP8.5, pH reductions exceeding −0.2 (−0.3) units are projected in close to 23% (~15%) of North Atlantic deep-sea canyons and ~8% (3%) of seamounts – including seamounts proposed as sites of marine protected areas. The spatial pattern of impacts reflects the depth of the pH perturbation and does not scale linearly with atmospheric CO2 concentration. Impacts may cause negative changes of the same magnitude or exceeding the current target of 10% of preservation of marine biomes set by the convention on biological diversity, implying that ocean acidification may offset benefits from conservation/management strategies relying on the regulation of resource exploitation
Interaction-controlled Brownian motion in a tilted periodic potential
No full textEvstigneev M, von Gehlen S, Reimann P. Interaction-controlled Brownian motion in a tilted periodic potential. Physical Review E. 2009;79(1): 011116.The drift and diffusion of a few interacting, overdamped Brownian particles in a tilted periodic potential are studied analytically and numerically. Both quantities exhibit a complex multipeaked structure as a function of the equilibrium interparticle separation. Upon variation of the interaction strength, both drift and diffusion may exhibit a nonmonotonic, resonancelike behavior
Uncovering the big players of the web
No full textIn this paper we aim at observing how today the Internet large organizations deliver web content to end users. Using one-week long data sets collected at three vantage points aggregating more than 30,000 Internet customers, we characterize the offered services precisely quantifying and comparing the performance of different players. Results show that today 65% of the web traffic is handled by the top 10 organiza- tions. We observe that, while all of them serve the same type of content, different server architectures have been adopted considering load bal- ancing schemes, servers number and location: some organizations handle thousands of servers with the closest being few milliseconds far away from the end user, while others manage few data centers. Despite this, the performance of bulk transfer rate offered to end users are typically good, but impairment can arise when content is not readily available at the server and has to be retrieved from the CDN back-en
Enhancing the Digital Backchannel Backstage on the Basis of a Formative User Study
No full textContemporary higher education with its large audiences suffers from passivity of students. Enhancing the classroom with a digital backchannel can contribute to establishing and fostering active participation of and collaboration among students in the lecture. Therefore, we conceived the digital backchannel Backstage specifically tailored for the use in large classes. At an early phase of development we tested its core functionalities in a small-scale user study. The aim of the study was to gain first impressions of its adoption, and also to form a basis for further steps in the conception of Backstage. Regarding adoption we particularly focused on how Backstage influences the participants' questioning behavior, a salient aspect in learning. We observed that during the study much more questions were uttered on Backstage than being asked without backchannel support. Regarding the further development of Backstage we capitalized on the participants' usability feedback. The key of the refinement is the integration of presentation slides in Backstage, which leads to an interesting reconsideration of the user interactions of Backstage
