Population dynamics of minimally cognitive individuals. Part I: Introducing knowledge into the dynamics

Description: The author presents a new approach for modeling the dynamics of collections of objects with internal structure. Based on the fact that the behavior of an individual in a population is modified by its knowledge of other individuals, a procedure for accounting for knowledge in a population of interacting objects is presented. It is assumed that each object has partial (or complete) knowledge of some (or all) other objects in the population. The dynamical equations for the objects are then modifie… more

Proc. Agent 2004 Conf. on Social Dynamics : Interaction, Reflexivity and Emergence

Description: I'd like to welcome you to the Agent 2004 conference. As most of you are aware, this conference is the fifth in a series of meetings that began in 1999. A conference followed the next year in 2000. The 2001 conference was skipped because of some conflicts with other conferences, and the conferences have proceeded annually since then. We have the proceedings of the previous conferences available here on CDs. One CD has the proceedings from 1999, 2000, and 2002; the other contains last year's pro… more

Impact of power plants on aquatic systems: a social perspective

Description: Topics discussed are: aquatic effects of thermal electric power stations; legal aspects of water pollution; EPA provisions for levels of thermal discharges to assure protection and propagation of a balanced, indigenous population of shellfish, fish, and wildlife in a body of water; cost benefit analysis of steam electric power effluents; cooling systems and siting of power plants; simulation modeling of population dynamics; and sociological aspects of water pollution.

Studying the incommensurability that unites us: persuasion across discourse communities, persuasion via boundary objects

Description: In the science studies literature the theoretical construct of boundary objects has been developed to explain how diverse communities clustered around a scientific subject area cooperate to advance that area. Boundary objects are 'scientific objects that inhabit several intersecting social worlds . . . and satisfy the informational requirements of each of them' (Star and Griesemer 393). Star and Griesemer's foundational article showed that these objects can be shared by communities ranging from… more

In Situ Tracer method for establishing the presence and predicting the activity of heavy metal-reducing microbes in the subsurface. Final Report

Description: Tracer method to establish presence and distribution of chromium reducing microbes. The primary objective of this research was to establish an in situ tracer method for detecting the presence. distribution. and activity of subsurface heavy metal-reducing microorganisms. Research focused on microbial systems responsible for the reduction of chromium and a suite of biotracers coupled to the reduction process. The tracer method developed may be used to characterize sites contaminated with chromium… more

Manpower assessment brief: May 1995, No. 31

Description: The Health Physics/Radiation Protection Enrollments and Degrees, 1994 survey consisted of 53 institutions offering a major in health physics/radiation protection or radiation health, or an option program equivalent to a major (for example, in radiobiology or biophysics). Of the 53 programs, 1 program was new to the survey, 4 programs were suspended, allowing the students to complete their degrees, and 1 undergraduate program was suspended and reported the last degrees in 1994. As in previous ye… more

A QUICK KEY TO THE SUBFAMILIES AND GENERA OF ANTS OF THE SAVANNAH RIVER SITE

Description: This taxonomic key was devised to support development of a Rapid Bioassessment Protocol using ants at the Savannah River Site. The emphasis is on 'rapid' and, because the available keys contained a very large number of genera not known to occur at the Savannah River Site, we found that the available keys were unwieldy. Because these keys contained many more genera than we would ever encounter and because this larger number of genera required more couplets in the key and often required examinati… more

CHARACTERIZATION OF WILD PIG VEHICLE COLLISIONS

Description: Wild pig (Sus scrofa) collisions with vehicles are known to occur in the United States, but only minimal information describing these accidents has been reported. In an effort to better characterize these accidents, data were collected from 179 wild pig-vehicle collisions from a location in west central South Carolina. Data included accident parameters pertaining to the animals involved, time, location, and human impacts. The age structure of the animals involved was significantly older than th… more
