This paper explores the critical role of conversational threads in facilitating the ongoing,
distributed work of one virtual organization. In studying the electronic mail exchanges
of organizational members during one year, we found that they engaged in a range of
threading activity to establish and maintain continuity, coherence, and coordination in
their collaborative work over time. In particular, we found that organizational members
relied on simple threads to focus their attention and action on a particular topic over a
short period of time, concurrent threads to enable their participation in multiple topics
at the sa...
This is a partial theory of thinking, combining a number of classical and modern concepts from psychology, linguistics, and AI. Whenever one encounters a new situation (or makes a substantial change in one's viewpoint) he selects from memory a structure called a frame, a remembered framework to be adopted to fit reality by changing details as necessary. A frame is a data-structure for representing a stereotyped situation, like being in a certain kind of living room, or going to a child's birthday party. Attached to each frame are several kinds of information. Some of this information is about how to use the frame. Some is about what one can expect to happen next. Some is about what to do if these expectations are not confirmed. The "top levels" of a frame are fixed, and represent things that are always true about the ...

Amphiphilic self-assembling peptides are functional materials, which, depending on the amino acid sequence, the peptide length, and the physicochemical conditions, form a variety of nanostructures including nanovesicles, nanotubes, and nanovalves. We designed lipid-like peptides with an aspartic acid or lysine hydrophilic head and a hydrophobic tail composed of six alanines (i.e., ac-A[subscript 6]K-CONH[subscript 2], KA[subscript 6]-CONH[subscript 2], ac-A[subscript 6]D-COOH, and DA[subscript 6]-COOH). The resulting novel peptides have a length similar to biological lipids and form nanovesicles at physiological conditions. AFM microscopy and light scattering analyses of the positively charged lipid-like ac-A[subscript 6]K-CONH[subscript 2], KA[subscript 6]-CONH[subscript 2] peptide formulations showed individual nanovesicles. The nega...
This course introduces students to probability and random variables. Topics include distribution functions, binomial, geometric, hypergeometric, and Poisson distributions. The other topics covered are uniform, exponential, normal, gamma and beta distributions; conditional probability; Bayes theorem; joint distributions; Chebyshev inequality; law of large numbers; and central limit theorem.
This subject examines the ways in which we read. It introduces some of the different strategies of reading, comprehending and engaging with literary texts developed in the twentieth century, paying special attention to post-structuralist theories and their legacy. (What poststructuralism means will be discussed often in this course, so don't worry if you don't know what it means right now!) The course is organized around specific theoretical paradigms. In general, we will: (1) work through selected readings in order to see how they determine or define the task of literary interpretation; (2) locate the limits of each particular approach; and (3) trace the emergence of subsequent theoretical paradigms as responses to the achievements and limitations of what came before. The literary texts and films accompanying the theoretical material ...
