Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

No full textA photograph of Pacific University athletic coach, Archie Hahn. The photograph appears to be cut out of the Heart of Oak, the Pacific University yearbook. Coach Hahn came to Pacific University in 1906. This photograph appears in a scrapbook compiled by Frances B. Clapp, a 1908 Pacific University graduate
Pavetta trichardtensis var. jabulanii N. Hahn 2022, var. nov.
No full textPavetta trichardtensis var. jabulanii N. Hahn, var. nov. (Fig. 1–3) Type:— SOUTH AFRICA. Limpopo: Hanglip, 6 December 2019, N . Hahn 3129 (holotype ZPB!; isotypes PRE!, PRU!) Diagnosis:— Pavetta trichardtensis var. jabulanii is easily distinguished from the typical variety by its glabrous, shiny dark green leaves with sunken bacterial nodules above and glabrous calyx opposed to pubescent thinly textured leaves with bacterial nodules not prominent above and pubescent calyx (Fig. 2). In addition, var. jabulanii has on average smaller leaves (1.8–)3.5–6.8(–8.7) × (0.9–)1.7–2.9(–3.5) cm and petioles (0.3–)0.3–0.9(–1.4) cm long opposed to (2.6–)4.4–8.3(–8.9) × (1.4–)1.9–3.8(–5.3) cm and petioles (0.4–)0.6–1.2(–1.5) cm long for var. trichardtensis. Distribution:—Soutpansberg, Blouberg and possibly Houtbosch [Woodbush] (Fig. 1). The specimen, Houtbosch, Rehmann 6016 (K) cited under the description of P. zoutpansbergensis (Bremekamp 1934) was not examined. Rehmann 6016 is presently the only specimen of P. trichardtensis var. jabulanii recorded south of the Soutpansberg and Blouberg (Fig. 1). Conservation status:— Least Concern (LC). Pavetta trichardtensis var. jabulanii encompasses an EOO of approximately 8891 km 2 and an AOO at a 2 km cell width of 88 km 2 or AOO at a 5 km cell width of 525 km 2. This variant was possibly collected south of the Soutpansberg in 1875. Even though var. jabulanii EOO and AOO would fall under the Vulnerable category, the Soutpansberg and Blouberg communities seem to be quite stable and therefore do not fulfil any of the additional criteria for such listing. This variety does not qualify for any of the threatened categories and is therefore assigned a conservation status of Least Concern. Eponymy:—I have the honour of dedicating the specific epithet to Jabulani Linden, long standing friend and naturalist par excellence who has assisted and collaborated with me over many years to the conservation and natural history of the Soutpansberg. Jabulani is a fitting epitaph which has its origin from the isiZulu word meaning “rejoice” as this is a joyous occasion, finally having resolved the identity of the glabrous variant of Pavetta trichardtensis.
