The Twice-Killed: Imagining Protest Suicide

The inspiration I take from J. M. Coetzee's book Elizabeth Costello (2003) is his advocacy of imagining as an alternative to rational thought. Imagining, as I understand him, is mindwork that engages the body as an experiential and metaphorical site. I apply this notion of imagining to suicides conducted in the service of political protest: The fatal hunger strike of ten prisoners in Northern Ireland in 1981 and Jan Palach's self-immolation in Prague in 1969. Three questions direct the exploration of their trajectories: What feeds the hope for the effectiveness of protest suicides? How do they use the body as a performance site? Do such suicides call for an ethics of attentiveness?     

An apparatus for the continuous culture of bacteria at constant generation times

Summary An apparatus for continuous culture of bacteria at constant generation times is described, analogous toNovick andSzilard's “chemostat” and the apparatus ofMonod. Detailed instructions for the use of the apparatus are given and a method for the determination of the vessel constant is described. The theory and the interesting possibilities of the apparatus for a number of fundamental problems in bacteriology are shortly discussed.     

Scanning electron microscope study of the palar pegs of three species of Corixidae (Hemiptera)

Scanning electron microscope studies were performed on the palar pegs of male forelegs of Trichocorixa sexcincta, Sigara alternata and Hesperocorixa interrupta. The studies showed the pegs to be basically conical and chevron-ridged, with a wide base that tapered of to a narrow apex. Clear species differences were apparent with respect to the size of the peg, the number of ridges on an individual peg, and the number and arrangement of the pegs on the pala. The possible behavioural and evolutionary significance of the palar pegs is discussed in relation to mating.     

Tiefsee-Aktinien der Familie Actinoscyphiidae aus dem IMordatlantik (Actiniaria, Mesomyaria)

Actinoscyphia saginata (Verrill, 1882; type species) and Actinoscyphia aurelia (Stephenson, 1918) are redescribed with special reference to characters of diagnostic significance in order to differentiate the two species both inhabiting the 2000 m slope region of the North Atlantic. In situ photograph of A. aurelia off the North West African coast shows it to display a novel life form type in expanding its bi-lobed tentacular disc like a Venus-fly-trap and standing on the muddy sediment with a small, non-adhesive base penetrating just below the surface of the sediment. The peculiar nematocyst equipment found in both species makes it necessary to rehabilitate the family Actinoscyphiidae Stephenson, 1920. The systematic position of the family is discussed and eventually the Actinoscyphiidae is considered as sister group (sensu Hennig) of the Hormathiidae. Because of the loss of acontia in the Actinoscyphiidae, this taxon is considered to be the more advanced one. Chondrodactis japonica Wassilieff, 1908, is found to belong to the genus Actinoscyphia.     

Ecology of migrant Black-necked Grebes Podiceps nigricollis at Mono Lake, California

Autumnal migrant Black-necked or Eared Grebes Podiceps nigricollis begin arriving in large numbers at Mono Lake, California, in August. Juveniles appear to arrive later than adults, and the number of grebes at Mono Lake peaks in September and October. The grebes leave by November or December. Stomachs of 73 grebes collected in the Autumns of 1980 and 1981 reveal that brine shrimp Artemia monica comprise over 90% of the diet. The remainder of the diet is composed of the larvae, pupariaand adults of a brine fly Ephydra hians and small numbers of shore bugs Saldula arenicola and 5. opiparia and other terrestrial arthropods. The grebes do not feed at night but rest instead in large nocturnal aggregations over deep water. Grebe fat stores and total body-weight increase from August to October, and adults moult their regimes in August and September. In late autumn brine shrimp densities decline dramatically and the grebes leave the lake.
