Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Derivatives of 1-(3-methoxy-4-acetoxyphenyl)-2,6-dicarbethoxy-cyclohexanedione-3,5
No full textPapadakis has synthesized the following substances: 1-(p-Acetoxyphenyl)-2,6-dicarbethoxy-cyclohexanedione-3,5 (I), 4-Hydroxphenyl-cyclohexanedione-3,5 (II), l-(p-Acetoxyphenyl)-2,6-dicarbethoxy-4-carbethoxymethyl-cyclohexanedione-3,5 (III), which are good starting materials for the further synthesis of substitutes for cardiac glycosides (IV) and hormones because they have the necessary functional groups in proper locations.|Papadakis and Scigliano have also synthesized 1-(3-Methoxy-4-acetoxyphenyl)-2,6-dioarbethoxy-cyclohexane- dione-3,5 (VII). They reacted vanillin with diethyl malonate to form Ethyl- (3-Methoxy-4-hydroxy)-benzalmalonate (v). (V) was acetylated to form Ethyl-(3-Methoxy-4-acetoxy)-benzalmalonate (V). (V) was reacted with acetoacetic ester and sodium ethoxide to give (VII). The object of this investigation is to prepare derivatives of (VII) which may be of physiological importance. In this research the preparation of a dye and a sulfone gives a beginning to further research in the two fields of dyes and sulfones. It is known that some dyes are of pharmaceutical as well as industrial importance, such as prontosil. Lately sulfones have attracted more attention since 4,4'-diamino-diphenylsulfone has been shown to have effect against tuberculosis and leprosy.RAL Thesis 1949 A37Adrian_M-1949-MS.pd
