Identity Crisis: Experimental Film and Artistic Expansion∗

Abstract: OCTOBER 137, Summer 2011, pp. 23–50. © 2011 October Magazine, Ltd. and Massachusetts Institute of Technology. The radical transformations that took place in the arts after the Second World War reached a crescendo in the 1960s. The nature and possibilities of each art form were fundamentally rethought, while the idea that these art forms could be clearly distinguished from one another gave way to intensive experimentation with cross-fertilization and mixing. Recall Allan Kaprow’s statement, “The young artist of today need no longer say ‘I am a painter,’ or ‘I am a dancer.’ He is simply an ‘artist.’”1 Or this definition by Joseph Kosuth:

Laser ablation production of Ba, Ca, Dy, Er, La, Lu, and Yb ions

Abstract: We use a pulsed nitrogen laser to produce atomic ions by laser ablation, measuring the relative ion yield for several elements, including some that have only recently been proposed for use in cold trapped ion experiments. For barium, we monitor the ion yield as a function of the number of applied ablation pulses for different substrates. We also investigate the ion production as a function of the pulse energy, and the efficiency of loading an ion trap as a function of radiofrequency voltage.

Effects of Salinity on Survivorship of Wood Frog (Rana sylvatica) Tadpoles

Abstract: We examined the survivorship of wood frog (Rana sylvatica) tadpoles when exposed continuously to various concentrations of sodium chloride, a common component of road salt. A high environmental concentration of NaC1 (5.6 g L−1) resulted in decreased survivorship within a short period of time compared to controls; lower concentrations of NaC1 also decreased survivorship, but the effect took longer to appear. These results indicate that environmental salinization, as results from road salt run-off, will have negative consequences for the wood frog.

Temperature-related biodiversity change across temperate marine and terrestrial systems

Abstract: Climate change is reshaping global biodiversity as species respond to changing temperatures. However, the net effects of climate-driven species redistribution on local assemblage diversity remain unknown. Here, we relate trends in species richness and abundance from 21,500 terrestrial and marine assemblage time series across temperate regions (23.5-60.0°) to changes in air or sea surface temperature. We find a strong coupling between biodiversity and temperature changes in the marine realm, which is conditional on the baseline climate. We detect increases in species richness with increasing temperature that is twice as pronounced in warmer locations, while abundance declines with warming in the warmest marine locations. In contrast, we did not detect systematic temperature-related richness or abundance trends on land, despite a greater magnitude of warming. We also found no evidence for an interaction between biodiversity change and latitude, further emphasizing the importance of baseline climate in structuring assemblages. As the world is committed to further warming, significant challenges remain in maintaining local biodiversity amongst the non-uniform inflow and outflow of “climate migrants” across distinct regions, especially in the ocean.
