the aesthetic dimension of howard barkers art: a frankfurtian approach to scenes from an execution and no end of blame
رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
Fluff-thieving birds sabotage seed dispersal
Characterizing many species interactions as mutualisms can be misleading because some members of the interaction derive greater fitness benefits at the expense of other members. We provide detailed natural history data on a suspected bird-plant mutualism in South Africa where many species of birds use fluffy Eriocephalus seed material to construct their nests, potentially dispersing seeds for t...
متن کاملSaturn’s Mysterious Arc-embedded Moons: Recycled Fluff?
Introduction: The satellites of Saturn less than 150 km radius occupy several dynamical niches: within rings (Pan, Daphnis, Atlas, Prometheus, Pandora), Coorbiting (Janus and Epimetheus), orbiting among faint rings or in ring arcs (Aegaeon, Methone, Anthe, Pallene) [1], and populating libration regions of larger moons (Telesto, Calypso, Polydeuces, and Helene). Hyperion orbits between Titan and...
متن کاملThe Local Bubble, Local Fluff, and Heliosphere
The properties of the Local Bubble, Local Fluff complex of nearby interstellar clouds, and the heliosphere are mutually constrained by data and theory. Observations and models of the diffuse radiation field, interstellar ionization, pick-up ion and anomalous cosmic-ray populations, and interstellar dust link the physics of these regions. The differences between the one-asymmetric-superbubble an...
متن کاملBi-directional Static Load Testing – State of the Art
The use of static load testing in optimising design and providing verification of suitability and constructability continues to be unsurpassed in the foundation industry. The utilisation of top load reaction testing appears to be that with which most European engineers are familiar, but a variation on this, which has become just as conventional in some parts of the world, is the use of bi-direc...
