Supplementary work on individual or group basis. Registration subject to prior arrangement for subject matter and supervision by staff. From the course home page: Millions of people are on-line today and the number is rapidly growing - yet this virtual crowd is often invisible. In this course we will examine ways of visualizing people, their activities and their interactions. Students will study the cognitive and cultural basis for social visualization through readings drawn from sociology, psychology and interface design and they will explore new ways of depicting virtual crowds and mapping electronic spaces through a series of design exercises.

This course is a graduate reading seminar, in which historical and contemporary studies are used to explore the interaction of technology with social and political values.

Examples are drawn from the technologies of war, transportation, communication, production, and reproduction.

This course is an introduction to the theory that tries to explain how minds are made from collections of simpler processes. It treats such aspects of thinking as vision, language, learning, reasoning, memory, consciousness, ideals, emotions, and personality. It incorporates ideas from psychology, artificial intelligence, and computer science to resolve theoretical issues such as wholes vs. parts, structural vs. functional descriptions, declarative vs. procedural representations, symbolic vs. connectionist models, and logical vs. common-sense theories of learning.

This seminar provides an introduction to scholarship in a growing research community: the sociologists and sociologically-inclined organization theorists who study issues that relate, at least in a broad sense, to the interdisciplinary field of inquiry that is known as "strategy" or "strategic management" research. The course is not designed to survey the field of strategy. Rather, the focus is on getting a closer understanding of the recent work by sociologists and sociologically-oriented organization theorists that investigates central questions in strategic management. In particular, we will be concerned with identifying and assessing sociological work that aims to shed light on: (a) relative firm performance; (b) the nature of competition and market interaction; (c) organizational capabilities; (d) the beginnings of industries and firms; (e) the diffusion of transfer of ideas and practices across firms; and (f) strategic change.

Students are provided with an understanding of sound and light waves through a "sunken treasure" theme a continuous storyline throughout the lessons. In the first five lessons, students learn about sound, and in the rest of the lessons, they explore light concepts. To begin, students are introduced to the concepts of longitudinal and transverse waves. Then they learn about wavelength and amplitude in transverse waves. In the third lesson, students learn about sound through the introduction of frequency and how it applies to musical sounds. Next, they learn all about echolocation what it is and how engineers use it to "see" things in the dark or deep underwater. The last of the five sound lessons introduces acoustics; students learn how different materials reflect and absorb sound.
