Prionocerus viridiflavus Geiser 2007
No full textPrionocerus viridiflavus Geiser, 2007 Prionocerus viridiflavus Geiser, 2007: 168. Type material examined: Holotype 3 and 2 paratypes 3 and Ƥ, NHMB, see Geiser, 2007 for details. This species was described in a recent paper, so there is no need to repeat all details of the description here. A photograph of the habitus is given in fig. 39 (3), a drawing of the last male abdominal sternite in fig. 25. Differential diagnosis: Very easily recognizable by uniformously green pronotum and large yellow humeral patches on the elytra, as well as by the distinctive shape of the elytra (narrowed in the middle, slightly dilated subapically). The last abdominal sternite in males is smallest of all Prionocerus, the aedeagus somewhat similar to P. coeruleipennis. Distribution (fig. 45): So far known only from three localities on the island of Sumatra, Indonesia. It seems to be endemic to this island.Published as part of Geiser, Michael, 2010, Studies on Prionoceridae (Coleoptera: Cleroidea). II.

Carl Friedrich Geiser and Ferdinand Rudio : the men behind the first International Congress of Mathematicians
No full textThe first International Congress of Mathematicians (ICM) was held in Zurich in 1897, setting the standards for all future ICMs. Whilst giving an overview of the congress itself, this thesis focuses on the Swiss organisers, who were predominantly university professors and secondary school teachers. As this thesis aims to offer some insight into their lives, it includes their biographies, highlighting their individual contributions to the congress. Furthermore, it explains why Zurich was chosen as the first host city and how the committee proceeded with the congress organisation.
Two of the main organisers were the Swiss geometers Carl Friedrich Geiser (1843-1934) and Ferdinand Rudio (1856-1929). In addition to the congress, they also made valuable contributions to mathematical education, and in Rudio’s case, the history of mathematics. Therefore, this thesis focuses primarily on these two mathematicians.
As for Geiser, the relationship to his great-uncle Jakob Steiner is explained in more detail. Furthermore, his contributions to the administration of the Swiss Federal Institute of Technology are summarised. Due to the overarching theme of mathematical education and collaborations in this thesis, Geiser’s schoolbook "Einleitung in die synthetische Geometrie" is considered in more detail and Geiser’s methods are highlighted.
A selection of Rudio’s contributions to the history of mathematics is studied as well. His book "Archimedes, Huygens, Lambert, Legendre" is analysed and compared to E W Hobson’s treatise "Squaring the Circle". Furthermore, Rudio’s papers relating to the commentary of Simplicius on quadratures by Antiphon and Hippocrates are considered, focusing on Rudio’s translation of the commentary and on "Die Möndchen des Hippokrates". The thesis concludes with an analysis of Rudio’s popular lectures "Leonhard Euler" and "Über den Antheil der mathematischen Wissenschaften an der Kultur der Renaissance", which are prime examples of his approach to the history of mathematics

Decentralisation meets local complexity: conceptual entry points, field-level findings and insights gained
No full textThis article summarises and discusses eight case studies from Mexico, Argentina, Bolivia, Pakistan, India and Nepal that focus on the everyday realities of decentralisation. It recalls the mainstream arguments favouring decentralisation as a basic human right (i.e. to be able to participate in decision-making) and in a more utilitarian sense (i.e. decentralisation for development). The eight case studies support aspects of the mainstream; however, they also present new insights. To position these insights, the article deconstructs mainstream decentralisation discourses as based on a functionalist ontology, often leading to rather managerial and mechanistic approaches. To contrast such a functionalist position, three critical social science perspectives are introduced: the neo-Marxist view of the hegemonic state (including the notion of subalterns), Scott’s simplifying state techniques, and Midgal’s state-in-society approach. A reading of the case studies in this context highlights that decentralisation programmes often follow standardised procedures that encounter social, political, economic and ecological local complexities. Dimensions of these complexities are: already
ongoing contestations among social groups; conflicting expectations upon, and interpretations of, the meaning of decentralisation; and strategic handling of decentralisation as a resource – highlighting the importance of agency. The article concludes with the proposition that decentralisation is not primarily a managerial challenge (i.e. to introduce improved governance
mechanisms), but is inherently political, influenced by interests and agency, and thus contingent. The challenge for researchers and practitioners is to support adequate social processes that allow decentralisation to give local
complexities more room, without fuelling local competition over the scarce resources offered by decentralisation

Brancucci” [white printed label]. “ Holotype Lamellipalpus longipalpis n.sp. Brancucci & Geiser 08” [red printed label]. 13 paratype (NHMB): “Chivo Busty, 21.IV. 1985, India, Darjeeling D., Narayan B. 13 paratype (NHMB): “Umg. Kalimpong, Darjeeling Distr., India, Bhakta B., 11.IV. 1979 ”. Both paratypes labelled as follows: “ Paratype Lamellipalpus longipalpis n.sp. Brancucci & Geiser 08” [red printed label]. Etymology: The name was selected for this species because of the remarkably long palpi. Remarks: The 2 paratypes differ in some minute features from the holotype. The specimen from Umg. Kalimpong has the same head configuration and similar long palpi, whilst the specimen from Chivo Busty has shorter palpi and a larger head with more widely separated eyes. Furthermore, both specimens are of smaller size, 6.5 mm against 8.0 mm, but the colour of the elytra is almost identical to that of the holotype. Affinities: This species can be distinguished from all other known species by the testaceous brown elytra with an oblique dark brown band, by the suparallel body, and by the larger head and extremely long maxillary and labial palpi.
