Filling a House with Meaning: The Construction of a Chicago Housing Cooperative

A housing cooperative is a non-profit form of housing tenure that has been a feature of American university campuses since the 1930s. Living in a co-op allows members the benefits of low rent, a close-knit social group, and democratic control of their living space. Unlike communes, however, members do not typically share income or unite around a particular ideology. This paper is the result of ethnographic research of one such house, Haymarket House of Qumbya Housing Cooperative in Hyde Park, Chicago. In 1988 the founders of Haymarket established its methods of structuring everyday life on principles of socialism, egalitarianism, and environmentalism. Since then, as residents have come and gone, the community has shifted away from its politically-charged origins, though members are still conscious of the political implications of their everyday life. This article seeks to understand the character of people’s lived experience with co-op living and the relationships of the people of Haymarket to the ideologies “built in” to their everyday practices. Though ethnographic research revealed that members differ in their attitudes about the concepts of utopia and intentional community, they share a desire to live differently than their neighbors, and Haymarket allows them a space to imagine alternatives

Multiple crossings of a very thin plasma sheet in the Earth's magnetotail

High resolution magnetic field, plasma and energetic particle data from the IMP-8 spacecraft were studied for multiple crossings of the Earth's magnetotail plasma sheet when it becomes thin during magnetospheric substorms. Traversals recur on a time scale of several minutes and they are associated with high velocity plasma flows that are usually directed tailward but are occasionally directed earthward for brief intervals. Observations are explained by rapid oscillations of a plasma sheet that is only a few thousand km thick, a dimension comparable to the gyroradius of energetic protons. Differences in the angular distributions of the two energies indicate that the higher energy protons are preferentially located on field lines deeper in the tail lobe. A neutral line acceleration model is supported tailward streaming energetic electrons which are occasionally present at the lobe plasma sheet interface

Multiple-satellite studies of magnetospheric substorms: Plasma sheet recovery and the poleward leap of auroral-zone activity

Particle observations from pairs of satellites (Ogo 5, Vela 4A and 5B, Imp 3) during the recovery of plasma sheet thickness late in substorms were examined. Six of the nine events occurred within about 5 min in locations near the estimated position of the neutral sheet, but over wide ranges of east-west and radial separations. The time of occurrence and spatial extent of the recovery were related to the onset (defined by ground Pi 2 pulsations) and approximate location (estimated from ground mid-latitude magnetic signatures) of substorm expansions. It was found that the plasma sheet recovery occurred 10 - 30 min after the last in a series of Pi bursts, which were interpreted to indicate that the recovery was not due directly to a late, high latitude substorm expansion. The recovery was also observed to occur after the substorm current wedge had moved into the evening sector and to extend far to the east of the center of the last preceding substorm expansion

Simultaneous measurements of magnetotail dynamics by IMP spacecraft

Changes in tail energy density during substorms in the magnetotail are given. In addition to plasma sheet thinnings seen prior to substorm onsets, a gradual decrease in plasma beta was detected in the deep tail which precedes onset and the more prominent plasma disappearance that typically accompanies it. The frequency of thinnings and the regions over which they occurred indicate that drastic changes in plasma sheet thickness are common features of substorms which occur at all locations across the tail
