15.676 Work, Employment, and Industrial Relations Theory (MIT)
This seminar will cover the multi-disciplinary theoretical and empirical foundations of research on work, employment, labor markets, and industrial relations. We begin by tracing the historical development of theory and research in the field, paying special attention to how the normative premises, concepts, and methodological traditions of industrial relations compare to those of other disciplines that contribute to the study of work and employment relations. Then we will review a number of curr

The Herd Mentality: Uncertain Returns Raise Questions About the Payback for Cleantech Investment
Using tax credits, low-interest loans and grants, the Obama Administration reportedly plans to invest more than $50 billion in electric vehicles, renewable energy and a host of other clean technology -- or "cleantech" -- ventures by the end of next year. But to what extent is today's fast-paced investment in cleantech a victim of irrational exuberance and the herd mentality often associated with venture capitalism? Quite a lot, say experts at Wharton and in the larger investment community.

21A.850J The Anthropology of Cybercultures (MIT)
This course explores a range of contemporary scholarship oriented to the study of 'cybercultures,' with a focus on research inspired by ethnographic and more broadly anthropological perspectives. Taking anthropology as a resource for cultural critique, the course will be organized through a set of readings chosen to illustrate central topics concerning the cultural and material practices that comprise digital technologies. We'll examine social histories of automata and automation; the trope of t

Introduction

In this unit you will consider key developments in the English language from the end of the fifteenth century to the nineteenth century. You will study how the social and political changes of this period affected the English language as well as the development of new tools and ways of thinking about language.

Firstly, however, some useful ‘tools of the trade’ – you'll take a look at some vital foundations of English grammar.

9 Summary

In this unit you have found out that:

  • The sensation of pain is caused by the release of a chemical (prostaglandin) that stimulates the nerve endings and sends an electrical message to the brain.

  • Pain can be reduced if the formation of prostaglandin can be inhibited.

  • Prostaglandin is formed, from arachidonic acid, in a cavity in the active site of the enzyme cyclooxygenase (COX).

  • Geometrical isomerism can be

Crowd Simulation for Urban Planning
This paper presents a semi-automatic visualization method for the evaluation of urban environments that is based on artificial intelligence. It proposes the use of agent-based crowd simulation software on a mid-scale urban planning level for design evaluation. The information on agents? movements is noted in standard raster images. The results are maps that are easy to understand. These maps show movement paths of the agents and density and give further conclusion on bottlenecks in planning cont

A Closer Look at Black Holes: Part 1
Several new techniques are currently being employed to probe the strong gravitational field in the vicinity of black holes. Long baseline interferometry at sub-millimeter wavelengths sets constraints on the silhouette of the black holes in the Galactic Center (SgrA*) and M87. Stars which get tidally disrupted as they orbit too close to a single black hole are being discovered at cosmological distances. Electromagnetic counterparts of black hole binaries in galaxy mergers are being identified,
