Without his help, the completion of this thesis would be impossible. His friendship and advices are precious to my professional and personal growth and will help me overcome many difficulties in my future career. I would like to take the opportunity to thank Prof. David J.W. Grant, who was my advisor during the first three years in graduate school and led me into the research area of physical pharmacy. It was my great honor to have worked for him, and he will always live as a role model in my life. Many thanks to Dr. Zheng Jane Li at Boehringer Ingelheim Pharmaceuticals (BI) for her invaluable advice as an industrial mentor and also for agreeing to serve on my committee. I sincerely appreciate her helpful discussions, revision of the manuscripts, and supervision of my research. I also want to thank her for providing me the internship opportunity at BI. I thank Dr. Timothy S. Wiedmann and Dr. Theodore P. Labuza for serving on my committee and for critically reviewing my thesis. I also want to thank Dr. Timothy S. Wiedmann for allowing me the use of the HPLC instruments in his lab and also for his advice as the Director of Graduate Studies.

  • Citation Success Index – an Intuitive Pair- Wise Journal Comparison Metric
    Citation success index – An intuitive pair- wise journal comparison metric Staša Milojević1, Filippo Radicchi1 and Judit Bar-Ilan2 1School of Informatics and Computing, Indiana University, Bloomington, USA 2Department of Information Science, Bar-Ilan University, Ramat Gan, 5290002, Israel In this paper we present “citation success index”, a metric for comparing the citation capacity of pairs of journals. Citation success index is the probability that a random paper in one journal has more citations than a random paper in another journal (50% means the two journals do equally well). Unlike the journal impact factor (IF), the citation success index depends on the broadness and the shape of citation distributions. Also, it is insensitive to sporadic highly-cited papers that skew the IF. Nevertheless, we show, based on 16,000 journals containing ~2.4 million articles, that the citation success index is a relatively tight function of the ratio of IFs of journals being compared, due to the fact that journals with same IF have quite similar citation distributions. The citation success index grows slowly as a function of IF ratio. It is substantial (>90%) only when the ratio of IFs exceeds ~6, whereas a factor of two difference in IF values translates into a modest advantage for the journal with higher IF (index of ~70%). We facilitate the wider adoption of this metric by providing an online calculator that takes as input parameters only the IFs of the pair of journals. 1. Introduction Most authors of research articles, whether in teams or as individuals, ultimately aim to maximize the impact of their publications, even when this goal is expressed as a desire to reach the widest possible audience (Gordon, 1984; Luukkonen, 1992).

In gaining this listing, we were advised at various points along the way by David Eisenberg, and also received help from Stephen Burley, Hans Deisenhofer and Brian Matthews, who wrote letters of support for our application. We thank David, Stephen, Hans and Brian for their time and help in making the application successful. In the last month, the entire first volume has been sent to the National Library of Medicine so that Acta Cryst. F will be accessible via PubMed from the first issue on and, confirming our own experiences, we have begun to hear from interested authors and others that their attempts at PubMed access have been successful. In addition to indexing by Medline, the journal has been accredited by the Institute for Scientific Information, leading to inclusion of articles in the Science Citation Index.
