Abstract
This paper presents a new finite element (FE) approach to modeling edge effects in beam sandwich structures. The approach is based on a mixed 2D and beam formulation conjuncted by means of a penalty function method. Several results from analysis of sandwich beams and frames bending with different boundary conditions and laminate properties are solved in order to demonstrate the accuracy of the algorithms and software developed. The influence of the penalty factor on the spectral condition number of the stiffness matrix and on the residual norm of the solution is also investigated for different isotropic and sandwich structures. The FE analysis of complex sandwich beam joint is subsequently presented. Results of this analysis show the advantages of the developed approach for large problems.

Abstract
From one angle, abortion law appears to confirm the regime politics account of the Supreme Court; after all, the Reagan/Bush coalition succeeded in significantly curtailing the constitutional protection of abortion rights. From another angle, however, it is puzzling that the Reagan/Bush Court repeatedly refused to overturn Roe v. Wade. We argue that time and again electoral considerations led Republican elites to back away from a forceful assertion of their agenda for constitutional change. As a result, the justices generally acted within the range of possibilities acceptable to the governing regime but still typically had multiple doctrinal options from which to choose.

Abstract
Ramp meters in the Twin Cities were turned off for 8 weeks in the Fall of 2000. This paper analyzes traffic data collected in this experiment on travel time variability with and without ramp metering for several representative freeways during the afternoon peak period. Travel time variability is generally reduced with metering. However, it is found that ramp meters are particularly helpful for long trips relative to short trips. The annual benefits from reducing travel time variability with meters are estimated to be $33.1 million, compared to the annual ramp metering costs of $2.6 million in the Twin Cities metro area. Thus, the impact on travel time variability should be captured in future ramp metering benefit/cost analysis.

Abstract
SOME popular journals have, for some time now, been publishing a short list of books which are selling successfully. Books and Bookmen has a feature of the best‐selling titles from two or three bookshops in town and the provinces; Time and Tide publishes a list compiled with the assistance of the National Book League: Time in its “Time Listings” enumerates the top twenty best sellers (of America) and similar lists no doubt appear in other journals. The outstanding characteristic of these lists is the remarkably high quality of the books mentioned. Rare indeed is a title which would not deserve a place on the shelves on any public library. Most of the titles are, of course, new, although it is interesting to note how really outstanding titles retain a place on the lists for many weeks. Thus in the last “Time Listing”, Dr. Zhivago, Breakfast at Tiffany's, and Aku Aku among others, have all been published for some months.

Abstract
This study challenges contentions that rights are limiting through an analysis of grassroots rights talk in the LGBTQ (Lesbian, Gay, Bisexual, Trans, and Queer) community in the 1980s. I argue that rights talk can be an important source of constructing community within local, nonmainstream, noninstitutional spaces through a discourse analysis of a forum for LGBTQ community-building in the past: the letters to the editor columns in Gay Community News. This study enhances law and social movement scholarship on the role of rights in social movements by exploring how rights discourse is employed by everyday people in a noninstitutional community-building venue rarely addressed in contemporary research.
