In this project, contemporary theater and performance art is examined in four cities in ex-Yugoslavia. War has pervaded all of the sites in some way, interrupting a sense of normalcy, altering the city physically as well as ideologically. For that reason, interaction with urban space becomes a central element in performances—whether it serves to preserve the city’s identity amidst destruction, to cleanse the city from the shame of official exploits, to break from the insular legacy of nationalism that flooded the streets, or to gather the city together in a process of collective healing.

Concern over sediment toxicity has increased the need for toxicity test information with organisms that inhabit sediments. Oligochaetes are exposed to toxicants through feeding and direct body contact with aquatic sediments. Chronic testing with oligochaetes has historically focused on tubificids with test lengths of one year or more to encompass several generations. Most naidid oligochaetes have generation times of three to seven days and could provide chronic information in a matter of weeks. The cosmopolitan distributed naidid, Pristina leidyi, was evaluated for use as a toxicity test organism. Results of research conducted includes culture methods, effects of temperature on reproduction, growth rates in a reference sediment, acute toxicity tests, and chronic toxicity tests.
