This work has undergone a double-blind review by a minimum of two faculty members from institutions of higher learning from around the world. The faculty reviewers have expertise in disciplines closely related to those represented by this work. If possible, the work was also reviewed by undergraduates in collaboration with the faculty reviewers. Theories suggest that humans may respond to stressful situations by engaging in certain social behaviors aimed at minimizing the effects of stress. Though these social responses during stress have been investigated in many ways, this study adds to the literature by using a standardized Q-sort technique to examine them. When participants characterized situations as more stressful, they reported a greater tendency to distance themselves from others and lesser expressions of warmth. For female participants only, when situations were described as more anxiety-inducing, participants reported greater seeking of assurance. Though male and female participants did not differ with respect to their reports of the stressfulness of situations, they did differ with respect to their reported behaviors in those situations, with female participants reporting more expressing of

Governments often promote inward foreign investment to encourage technology “spillovers” from foreign to domestic firms. Using panel data on Venezuelan plants, we find that foreign equity participation is positively correlated with plant produc-tivity (the “own-plant” effect), but this relationship is only robust for small enter-prises. We then test for spillovers from joint ventures to plants with no foreign investment. Foreign investment negatively affects the productivity of domestically owned plants. The net impact of foreign investment, taking into account these two offsetting effects, is quite small. The gains from foreign investment appear to be entirely captured by joint ventures.

functions is also common to organizations like large professional partnerships, financial mutuals and nonprofits. We contend that separation of decision and risk bearing functions survives in these organizations in part because of the benefits of specialization of management and risk bearing but also

Large-scale Internet applications can benefit from an ability to predict round-trip times to other hosts without having to contact them first. Explicit measurements are often unattractive because the cost of measurement can outweigh the benefits of exploiting proximity information. Vivaldi is a

Software engineers are faced with a dilemma. They want to write general and wellstructured programs that are flexible and easy to maintain. On the other hand, generality has a price: efficiency. A specialized program solving a particular problem is often significantly faster than a general program
