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
Four new species of Russula subsect. Cyanoxanthinae from China (Russulales, Russulaceae)
No full textFour new species of Russula subsect. Cyanoxanthinae, viz. Russula atrochermesina Y.L. Chen & J.F. Liang, R. lavandula Y.L. Chen, B. Chen & J.F. Liang, R. lilaceofusca Y.L. Chen & J.F. Liang and R. perviridis Y.L. Chen, B. Chen & J.F. Liang, from China are proposed, based on morphological and molecular evidence. Russula atrochermesina can be distinguished by its violet pileus with tuberculate-striate margin, distant lamellae that stain greyish-yellow when bruised, basidiospores ornamented by isolated warts, wide hymenial cystidia on lamellae edges, cystidia content negative reaction in sulphovanillin and branched subterminal cells in pileipellis. Russula lavandula has a purplish-white to violet red pileus with a yellow centre, frequently present lamellulae and furcations, stipe often with pale yellow near the base, isolated basidiospores ornamentation and unbranched cuticular hyphal terminations, while R. lilaceofusca is characterised by its lilac brown to dark brown pileus, crowded lamellae with lamellulae and furcations, stipe often turning reddish-yellow when bruised, subreticulate basidiospores ornamentation and clavate hymenial cystidia often with capitate appendage whose contents that change to reddish-black in sulphovanillin. Russula perviridis is characterised by its large basidiomata, smooth pileus surface, frequently present lamellulae and furcations, stipe with yellow-brown tinge, globose to broadly ellipsoid basidiospores with subreticulate ornamentation, long hymenial cystidia that turn greyish-black in sulphovanillin and symbiotic with Quercus semecarpifolia. Phylogenetic analyses, based on multi-gene ITS+LSU+mtSSU+rpb2, indicate that R. atrochermesina, R. lavandula, R. lilaceofusca and R. perviridis are closely related to R. pallidirosea and R. purpureorosea, R. banwatchanensis, R. lakhanpalii and R. nigrovirens, respectively

Diagnosis. Ichneumenoptera gryphus sp. nov. is similar to I. punicea Gorbunov & Arita 2000, which was described from northern Vietnam. I. gryphus. may be distinguished from I. punicea by having an additional yellow medial line in mesothorax. An orange band edged with yellow is present posteriad on each tergite of A 2 to A 7 in I. gryphus, whereas only a yellow bar is found in I. punicea. Distal end of saccus is rounded in I. gryphus, but truncated in I. punicea. Etymology. Specific name refers to an creature from Greek mythology, gryphus = gryphon. Biology. Adults was observed active during the day in June. The larva bores into the trunks of 2−8 cm in diameter of trees in the genus Machilus (Lauraceae) and feeds on callus, creating shallow galleries up to 2.5 cm long between the bark and the cambium layer covered with silk, debris, and frass. The larvae pupate in the following spring, but they clear the frass out of the tunnel and work their way to near the exit. Before the adult moth emerges, the pupa wriggles so that it projects from the entrance hole so that adult moth may stretch wings open emergence from pupal cases. Distribution. Known only from Taiwan.Published as part of Liang, Jia-Yuan & Hsu, Yu-Feng, 2015, A review of clearwing moths in the tribe Synanthedonini, with descriptions of six new species from Taiwan (Lepidoptera: Sesiidae), pp. 535-555 in Zootaxa 4044 (4) on pages 543-544, DOI: 10.11646/zootaxa.4044.4.4, http://zenodo.org/record/24356

Beatty, J.F., and the Law of Manslaughter
No full textIn this article, the author argues that the recent Supreme Court of Canada decisions in R. v. Beatty and R. v. J.F. have clarified several of the issues that have plagued the increasingly complicated offence of manslaughter. In particular, the decisions address the redundancy among the many manslaughter provisions in the Criminal Code, the need to define a clear separation between actus reus and mens rea, and the need to establish distinct categories of objective fault for different types of manslaughter offences. The author examines the legal background of these decisions as well as the current state of the law. He concludes by identifying emerging issues relating to the offence of manslaughter, arguing that the law remains convoluted and in need of urgent reform despite the progress made in the Beatty and J.F. decisions

No full textDe afgelopen jaren (2010 - 2015) zijn er in Nederland vele in het oog springende waterbouwkundige projecten gerealiseerd. Aansprekende voorbeelden betreffen onder meer Maasvlakte 2, de Zandmotor, de ontpoldering van de Noordwaard en de omlegging van de Zuid-Willemsvaart. Ook in de lokale watersystemen zijn diverse interessante projecten gebouwd. Veel van deze projecten hebben zich aangemeld voor de prof. dr. ir. J.F. Agemaprijs, dé prijs voor het beste en meest innovatieve waterbouwkundige project dat daadwerkelijk gebouwd is. Dit boek toont foto’s en projectinformatie, en bevat achtergrondinformatie over de Agemaprijs en essays van experts. De verschillende projecten geven een fraai beeld van de veelzijdigheid en innovativiteit van de Nederlandse (water)bouwers. Het boek geeft inzicht in de huidige en toekomstige manier waarop deltagebieden kunnen worden ingericht.Delft University of Technolog
