Sialis jianfengensis Yang, Yang & Hu
No full textSialis jianfengensis Yang, Yang & Hu (Figs. 2 & 10) Sialis jianfengensis Yang, Yang & Hu, 2002: 275. Diagnosis. Head orange with frons and clypeus black; pronotum yellowish brown with anterior margin dark; wings narrow, 1 / 3 of length. Female. Forewing length about 14–18 mm, hindwing length 13–16 mm. Head orange, vertex somewhat brown, frons and clypeus black. Compound eyes brown. Antenna black. Mouthparts black. Thorax black; pronotum yellowish brown with anterior margin blackish brown. Legs black. Wings narrow, 1 / 3 of length, grayish brown, forewings proximally darkened; veins dark brown. Abdomen black. Seventh sternite with posterior margin slightly elevated. Eighth sternite broad, subquadrate, moderately sclerotized except for a narrow median area. Ninth abdominal segement separated with a pair of membranous plates. Male. Unknown. Material examined. Holotype Ψ, CHINA: Hainan, Jianfengling, 1982. II. 22 / 26, H.Q. Chen & K.Z. Yun. Paratypes: 2 ΨΨ, same data as holotype. Distribution. China (Hainan). Remarks. This species distinctly differs from all the other Sialis species by the body coloration and the narrow wings. It seems to be related to some Protosialis species. In Protosialis species, the costal regions of the forewings are weakly dilated, and R 2 + 3 is only bifurcated. The lack of the male makes it difficult to determine the exact generic and specific status of this species. However, it is herein considered to be a true Sialis species by the distinctly dilated costal regions of the forewings and the four branched R 2 + 3.Published as part of Liu, Xingyue & Yang, Ding, 2006, Revision of the genus Sialis from Oriental China (Megaloptera: Sialidae), pp. 23-35 in Zootaxa 1108 on pages 27-29, DOI: 10.5281/zenodo.17149
Transformation of the Yang Hu "Inscription of Shed Tears" Narrative
Full text linkThough the stories of Jing Gong 景公 of the Qi 齊 weeping atop Mt. Niu 牛山 and Yang Hu 羊祜 of the Western Jin 西晉 weeping atop Mt. Xian 峴山 are similar in structure, they also differ in fundeamental ways. These differences serve to illustrate a transformation from ancient to medieval mentalities. Jing Gong's ascent is in keeping with the ancient incantatory practice of a ruler blessing his dominion; Yang Hu's tends more toward a medieval appreciation of natural beauty. In the former story Jing Gong's fear of death is ridiculed by a laughing Anzi 晏子; Yang Hu's narrative accords the transience of life with a sentimental lyricism without any counterpoint. During the Six Dynasties there was a proliferation of the Yang Hu-inspired banquets at which paticipants mourned the evanescence of life. It continued into the Tang, though increasingly the emphasis shifted away from grief focused upon the limitations of an individual's life span and toward a broader concept of death as a shered fate among men of all ages. During the Song Dynasty Yang Hu still received high marks as a statesman, but his lamentation of death lost its appeal, because of the growing popularity of new life-affirming ideas
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
