Contrasting roles: Eastern and Western European womenRoles en contrast: Femme d'Europe de l'est et de l'ouestRoles contrastantes: Las mujeres orientales y occidentales

The article presents an overview of the status of women in Western and Eastern Europe during the last decade. Relevant research in English is reviewed. Four indicators of women's status are treated: (1) equality before the law, (2) educational opportunities for women, (3) position in the labor force, and (4) level of leadership in social institutions. Successes and shortcomings in each division are cited; problem areas with presently incomplete information are indicated. The paper makes several recommendations for further research and better dissemination of information.     

The effects of individual and group contingencies on reading performance of special education students

The effects of individual and group contingencies on the reading performance of 10 special education students were examined in a counterbalanced multiple-baseline design with experimental manipulations introduced at random. During the Baseline condition no consequences for accuracy in programmed reading were in effect. With the Group Contingency, pupils earned points based on accuracy and exchanged them for activity backup reinforcers based on the average performance of the group. During the Individual Contingency arrangement, the same point totals were awarded by yoking pupils to the group behavioral criteria. The results indicated superior accuracy (from 2 to 25%) with the Group Contingency by all 10 pupils. Student preferences as to the two contingency arrangements indicated a slight preference for the Group Contingency phase. A lack of negative peer comments was noted over the duration of the experiment. Results were also discussed in terms of ease of implementation of the group contingencies within an ongoing token economy in a classroom setting. Tentative reasons for the differing results of the present study and others were presented.

The Impact of NIH Postdoctoral Training Grants on Scientific Productivity

In this paper, we estimate the impact of receiving an NIH postdoctoral training grant on subsequent publications and citations. Our sample consists of all applications for NIH postdoctoral training grants (unsuccessful as well as successful) from 1980 to 2000. Both ordinary least squares and regression discontinuity estimates show that receipt of an NIH postdoctoral fellowship leads to about one additional publication over the next five years, which reflects a 20% increase in research productivity.
