Family, Food, Nation, and Economy: Attachment to China and the Return (or Not) of Chinese Graduate Students in the Sciences and Engineering
For our project we sought to identify the meanings that male graduate students in the sciences and engineering mobilize when making plans for after they graduate. We conducted eight interviews and found that these students considered aspects such as family, food, nation, and economy when formulating their future plans. In particular, it appears that, now that China's economy is more similar to that of the United States, these students are allowed to reconsider values they have long held but were unable to make their priority. Furthermore, it also appears that there may be two groups among male graduate students in the sciences and engineering, if not graduate students in general -- those who return to China because they are attached to it and those who stay in the United States because they are not.unpublishe
Line Sources in Brans-Dicke Theory of Gravity
We investigate how the gravitational field generated by line sources can be
characterized in Brans-Dicke theory of gravity. Adapting an approach previously
developed by Israel who solved the same problem in general relativity we show
that in Brans-Dicke theory's case it is possible to work out the field
equations which relate the energy-momentum tensor of the source to the scalar
field, the coupling constant and the extrinsic curvature of a tube of
constant geodesic radius centered on the line in the limit when the radius
shrinks to zero. In this new scenario two examples are considered and an
account of the Gundlach and Ortiz solution is included. Finally, a brief
discussion of how to treat thin shells in Brans-Dicke theory is given.Comment: 21 pages, RevTex; added a discussion on the Gundlach and Ortiz

Gravitomagnetic time delay and the Lense-Thirring effect in Brans-Dicke theory of gravity
We discuss the gravitomagnetic time delay and the Lense-Thirring effect in
the context of Brans-Dicke theory of gravity. We compare the theoretical
results obtained with those predicted by general relativity. We show that
within the accuracy of experiments designed to measure these effects both
theories predict essentially the same result.Comment: 10 pages Typeset using REVTE
