The Dialectics of Identity of the Modern and Postmodern Art

Ako pojam identiteta shvatimo u hegelijanskom smislu kao iskustvo što ga svijest stječe o sebi, onda se taj pojam nameće kao ključan u razmatranju (vizualne) umjetnosti XX. stoljeća. Prema Hegelu, moderna umjetnost transcendira mogućnost adekvatnog izražavanja svoga duhovnog sadržaja pukom osjetilnom reprezentacijom (koja je kao takvu određuje) te stoga zahtijeva pojmovnu refleksiju. Budući da je umjetnost uvijek i dio stvarnosti i o stvarnosti, propitivanje njezina vlastita pojma ide ruku pod ruku s ontološkom problematikom. Epistemološke promjene koje konstituiraju i modernu i postmodernu odražavaju se tako u dijalektici pojma moderne i postmoderne umjetnosti. Prema nekim autorima ta je dijalektika određena značajnim promjenama u teoriji subjekta, kulturalnim razlikama i tehnologiji.If the notion of identity is considered in the Hegelian sense as the experience of the consciousness about itself, then this notion becomes of key importance in reflecting upon the 20th-century (visual) art. Modern art, in Hegel’s view, transcends the possibility of an adequate expression of its spiritual content by its merely sensuous representation (that defines it as such) and hence calls for a reflection on its notion. Since art has always been both part of and about reality, the questioning of its own notion goes hand in hand with the ontological problematics. The epistemological changes that constitute both Modernism and Postmodernism thus reflect themselves in the dialectics of the notion of modern and postmodern art. According to some authors, such dialectics is determined by important changes which took place in the theory of the subject, in cultural differences as well as in technology

The reinforcing property of ethanol in the rhesus monkey

Rhesus monkeys received intravenous injections of ethanol during daily sessions contingent on their presses on an available lever. Under the standard conditions, when each response on the lever during a 3-h period each day resulted in an i.v. injection of 0.1 g/kg ethanol, the monkeys made between 30 and 50 responses/session and developed blood ethanol levels of approximately 400 mg%. Under this and other conditions of response-contingent delivery of ethanol, a negatively accelerated pattern of self-injection within sessions was demonstrated. Variations in the dose per injection (0.05–0.2 g/kg/injection) resulted in changes in the rate of lever-pressing; the number of self-injections was inversely related to dose. Ethanol intake increased only slightly with increased dose per injection. Noncontingent administration of various doses of i.v. ethanol immediately prior to a daily session decreased the number of responses; the total amount of ethanol administered (contingent plus noncontingent), however, remained constant over a pretreatment dose range of 1 to 3 g/kg. When access time to ethanol was increased from 3 to 6 h/day, the total amount of ethanol taken increased slightly. However, the blood ethanol levels at the end of a 6-h session closely approximated those obtained following 3-h sessions, indicating that during the last 3–4 h of the 6-h sessions, the rate of ethanol intake closely matched the rate of ethanol elimination.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46404/1/213_2004_Article_BF00426785.pd

Scrapheap Challenge: A novel bulk-bone metabarcoding method to investigate ancient DNA in faunal assemblages

Highly fragmented and morphologically indistinct fossil bone is common in archaeological and paleontological deposits but unfortunately it is of little use in compiling faunal assemblages. The development of a cost-effective methodology to taxonomically identify bulk bone is therefore a key challenge. Here, an ancient DNA methodology using high-throughput sequencing is developed to survey and analyse thousands of archaeological bones from southwest Australia. Fossils were collectively ground together depending on which of fifteen stratigraphical layers they were excavated from. By generating fifteen synthetic blends of bulk bone powder, each corresponding to a chronologically distinct layer, samples could be collectively analysed in an efficient manner. A diverse range of taxa, including endemic, extirpated and hitherto unrecorded taxa, dating back to c.46,000 years BP was characterized. The method is a novel, cost-effective use for unidentifiable bone fragments and a powerful molecular tool for surveying fossils that otherwise end up on the taxonomic “scrapheap”
