共享领导胜任力构念与测量

共享领导作为一种不同于传统垂直型领导的新型领导不断受到研究者的关注。来自团队成员的共享领导行为,不仅需要团队成员具有共享领导的意愿,更需要团队成员具有共享领导的能力。为此,基于国内外学者关于共享领导相关研究文献回顾及访谈研究,探讨了共享领导胜任力构念及测量。研究提出共享领导胜任力由参与能力、激励能力和影响能力三维度构成,并对共享领导胜任力测量的有效性进行检验。共享领导胜任力的研究对团队有效提升共享领导具有一定的实践意义。

地图线状符号空间关系的处理

地图线状符号的空间关系的处理一般是解决由线状地理要素符号化后所带来的目标要素间在视觉上的冲突,尤其是当地图比例尺缩小时,所带来的冲突更加严重,但要处理此类空间关系就比较复杂。笔者提出了一些地图线状符号空间关系的处理方法并通过Visual C+6.0语言的编程进行了实验。

Australian species of Sinella (Coecobrya) Yosii, 1956 (Collembola: Entomobryidae)

The Australian members of the subgenus, Sinella (Coecobrya) Yosii, are revised. A new species from Western Australia, Queensland, and the Northern Territory, Sinella (Coecobrya) tropicalis sp. nov., is described, Sinella (Coecobrya) tenebricosa Folsom, 1902 is recorded from Australia for the first time, and new records of Sinella (Coecobrya) communis Chen and Christiansen, 1997 Chen, J‐X. and Christiansen, K. A. 1997. Subgenus Coecobrya of the genus Sinella (Collembola: Entomobryidae) with special reference to the species of China.. Annals of the American Society of Entomology, 90: 1–19.  [Google Scholar] are documented. Sinella (Coecobrya) caeca Schött, 1896 is considered a dubious record from Australia. A key is provided to the three known Australian species and a summary given of all dorsal and lateral chaetal patterns found on the fourth abdominal segment of subgenera Sinella Brook, 1882 Brook, G. 1882. On a new genus of Collembola (Sinella) allied to Degeeria Nicolet.. Journal of the Linnean Society of London (Zoology), 16: 541–545.  [Google Scholar] and Coecobrya Yosii, 1956 Yosii, R. 1956. Hohlencollembolen Japans II.. Japanese Journal of Zoology, 11(5): 609–627.  [Google Scholar]. The biogeography of the subgenus is described.     

A revision of Monocotyle Taschenberg, 1878 (Monogenea: Monocotylidae) with descriptions of three new species from Australia

Monocotyle is revised and three new species are proposed. Monocotyle corali sp. nov. is described from the gills of the cowtail ray, Pastinachus sephen (Forsskål) (Dasyatididae), and is distinguished from other members of Monocotyle by the large hamuli with a distinct tail on the guard and by the male copulatory organ with three loops and a wing-like accessory piece at the distal end. Monocotyle jordani sp. nov. from the gills of the southern eagle ray, Myliobatis australis Macleay (Myliobatididae), is differentiated by the male copulatory organ with a large, unique accessory piece. Monocotyle youngi sp. nov., from the gills of Himantura fai Jordan and Seale (Dasyatididae), has marginal haptoral papillae armed with 12 to 15 sclerites, a male copulatory organ with 20 loops and a unique accessory piece at the distal end. Monocotyle trygoni (Venkatanarsaiah and Kulkarni, 1980) Timofeeva, 1985 is synonymized with M. spirophallus Tripathi, 1959 and M. spirophallus is redescribed fully. There are now 16 valid species of Monocotyle and a key to species is presented. Additional data and illustrations of important taxonomic characters are provided. The developmental sequence of the male copulatory organ of M. spiremae Measures, Beverley-Burton and Williams, 1990 from juvenile to adult is described. The anterior glands and the type of secretion they contain are also documented for several species of Monocotyle.
