    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    The Dynamics of Part-Time Work

    This paper uses 14 years of data from the PSID to explore dynamic labor supply choices among adult women between full-time, part-time, or no labor market work. A variety of models indicate that past choices should be important in predicting current labor supply choices. This paper compares the effectiveness of several estimation strategies which require more or less historical information. The results indicate that past history in labor supply choices among adult women is very important in predicting current labor supply; given the lack of such data in many cases, the paper explores how much is lost when limited or no longitudinal information is available. In addition, the paper explores the substantive question of the role of part-time work in the labor market. Part-time workers are a very heterogeneous group; different part-time workers are in the midst of very different labor supply patterns. Most women use part-time work as a temporary alternative to full-time work or to being out of the labor market; few women use it as a transitional step into full-time employment. Simulations suggest the potential impact on future labor supply of mandating that low-skilled women who are out of the labor market enter part-time work.
