Cryptopeniculus nigrosetus Philips, new species
No full textCryptopeniculus nigrosetus Philips, new species (Figs. 1–16) DIAGNOSIS. This species can be recognized by the two elongate pronotal crests consisting of flocculant setae covered by combs of darker elongate but thick setae with their tips converging dorsally (Figs 1, 3). The crests are separated most widely anteriorly and converge posteriorly, becoming fused near the pronotal base. Additionally, the smooth, globular shape of the elytra (Fig. 1), the constriction and short longitudinal ridges at the elytral bases (Fig. 6), the ratio of ventrite lengths (Fig. 8), and the pronounced antennal fossae (Fig. 4) extending laterally from the antennal insertions should help differentiate this species from the other known African taxa. DESCRIPTION. Holotype. Sex not determined. Length from anterior edge of pronotum to apex of elytra 2.10 mm. Color light to dark reddish black (Figs 1–2). Head (Fig. 4): surface covered with scattered usually appressed short stout setae, those on frons above antennal fossae more erect, vertex surface adjacent to pronotum rough, frons distinctly smoother; antennal fossae separated by a ridge about 2 / 3 the maximum scape width, laterally with deep groove; clypeus crescent shaped with a pronounced posterior margin forming a ridge; labrum slightly emarginate, anterior margin with row of dense setae; labial and maxillary palps fusiform (Figs 12–13), mentum equilateral triangular shape (Fig. 14), mandible inner surface with indistinct tooth near middle (Fig. 15); eyes small and slightly projecting especially posteriorly, maximum length about as long as fourth antennomere, approximately 12 ommatidia at maximum length, 9 ommatidia at maximum width; antennae after scape gradually expanding in diameter to apex, second through 10 th antennomeres subequal, ultimate about 50 % longer than penultimate. Pronotum (Figs 1–3): setal clumps forming two crests in very broad “V” shape arising at anterior 1 / 5 at edge of abrupt chitinous triangular shaped ridge on either side of middle, lateral edges curving gradually posteriorly converging through to posterior 1 / 3 with setal crests continuing to posterior margin; crests formed of tightly spaced, juxtaposed, overlapping, long, brown to nearly black narrow setae, setal origins visible as projections around perimeter of crests, angled towards middle of crest, apical portion of setae strongly curved, tips converging at crest peak; basally setae angled anterioobliquely medially; beneath elongate setae a layer of paler colored flocculant setae in shape of broad “U”; anterior edge lined with erect setae similar to those forming external covering of crests, setae continuing onto lateral edge but not restricted, clump of setae laterally also forming loose tuft with setal tips converging dorsally to height below crest; lateroventrally pronotum covered with white or light colored closely appressed setae obscuring surface, setae extending along lateral posterior edge; perimeter of pronotum with large deep punctures approximately in a row, others more scattered, setae arising from conical projections producing distinctly uneven surface, medially a distinct narrow longitudinal groove between crests with setal inserts on either side. Elytra (Figs 1, 6): Surface glabrous except for very small widely spaced puncture rows, more visible laterally; punctures sometimes with small, short, usually appressed setae, sometimes more numerous near elytral apices, occasionally at base between grooves with thicker, erect, white appressed setae; laterally with single row of small brown recumbent overlapping setae extending from near base to about midpoint, a second row below of similarly located and spaced, appressed white setae more obliquely aligned, a third row extending along epipleura to about midpoint of white, closely appressed, very dense, obliquely aligned setae; near apex along suture with oblique parallel fine wrinkles. Ve nt r al surface (Figs. 5, 7– 8): Prothoracic process elongate, parallel sided, truncate at apex, extending posterior of procoxae into mesosternal groove, surface obscured with recumbent light or white colored setae, scattered recumbent setae; meso and metasternum with moderately dense appressed white setae, large, scattered, setose round punctures with posteriorly recumbent white setae; ventrites with some appressed white setae mainly around the perimeter although some extending medially along ventrite sutures, surface with scattered setose punctures smaller than those on metasternum and sometimes slightly less rounded, recumbent setae similar to those on metasternum; also with very fine punctures and fine regular reticular texture mainly along apices and fifth ventrite except at middle; ratio of ventrite lengths at middle starting anteriorly 16: 18: 14: 13: 26. Legs (Figs 1–2): With scattered white recumbent setae, apices of femora with stouter brown setae, femora approximately parallel sided, expanding to club about middle on pro and mesolegs, at apical 3 / 5 on metalegs; first metatarsomere slightly longer than fifth, second through fourth shorter and equal in length, covered with scattered white and brown recumbent setae. Genitalia: Male parameres (Figs 9–10) gradually decreasing in width towards apex, tips curved inwards, blunt, apical half with scattered setae; median lobe gradually narrowed to apex. Female genitalic coxites elongate (Fig. 11); stylus apex broad, slightly excavated; baculum elongate; spermatheca unsclerotized, not apparent. Sexual dimorphism. No consistent external differences between the sexes have been found. TYPE SERIES. Data on separate labels on the pins is indicated by the “/” and is as follows: Holotype: S. Afr.

Holotype and paratypes are deposited in the Museum of Natural History, Northern Flagship Institution (formerly the Transvaal Museum). Additional paratypes are deposited in the following collections: Canadian Museum of Nature, Gatineau, Quebec (CMNC), Natural History Museum, London (NHMC), United States National Museum, Washington D.C. (USNM), Muséum national d'Histoire naturelle, Paris (MNHN), Xavier Bellés collection and the T.K. Philips collection (TKPC). VARIATION. Length from anterior edge of pronotum to apex of elytra averages 1.97 0.16 mm (n = 25). Specimens from the most northern site have more pronounced carinae along the lateral margins of the interantennal space. They are also slightly darker, have two widely spaced long erect setal rows on the dorsal surface of the elytra, and the legs are slightly stouter. ETYMOLOGY. Based on the Latin adjective for black and noun for hair in reference to the coarse black setae on the pronotum. DISTRIBUTION. This monotypic genus ranges from about 10 km north of Lambert’s Bay in the Western Cape Province northwards through to near Nariep (approximately 30 km southwest of Garies) in the Northern Cape Province (Fig. 16). BIOLOGY. This species may be associated with coastal hummocks, vegetated dunes and other sandy habitats where it is undoubtedly scavenging on organic matter, most likely dung or other accumulated detritus. It has been captured with pitfalls usually set for 60 days and baited with faeces, fermenting bananas, and meat. Like most ptinines in these habitats, individuals are opportunistic and will feed on and attempt to breed in a wide variety of potential food sources.Published as part of Philips, T.

First Maltese record of Stephanopachys quadricollis (Marseul, 1879) (Coleoptera, Bostrichidae)
No full textThree specimens of Stephanopachys quadricollis (Marseul, 1878) were recently found in Malta in UV light
traps and represent the first record of this species for this country. Although S. quadricollis is native to
the Mediterranean basin, it is not yet clear if these Maltese records are due to a natural population or to
an interception. Distributional, nomenclatural and biological data on this species are summarized, and a
new synonymy is established: Stephanopachys quadricollis (Marseul, 1879) = Stephanopachys quadraticollis

T.K. Cureton's Tip: How the Kinesiology Department Founder and Professor at the University of Illinois Led Roger Bannister to Break the Four Minute Mile
No full textThis project investigates the events leading up to Roger Bannister???s record-breaking four minute mile in 1954. It focuses on the role of T.K. Cureton, founder of the kinesiology department and professor of physical education at the University of Illinois, who conducted research on training habits of athletic champions. On the basis of literature, internet, and archival research, the study finds that Cureton advised Bannister to train the whole body rather than sport specific areas during their meeting in London, which was the tip leading to Bannister???s record. The author further discusses the careers of these two men, the context of their meeting, and the myth of the impossible.unpublishedU of I OnlyRequested by Student

Versatile London: Water resilient urban design in fast changing conditions
No full textThe main goal of this graduation project - based on the desire to create a resilient urban environment -is to prevent the city of London from flooding, retrench the pressure in existing areas and to reduce the need for the «super sewer». Moreover the phases of transformation from existing space to a new form, function, or facilities are investigated. In this case the aim is to illustrate how adaptable existing urban fabric can be. This adaptive urban fabric contributes to more attractive and vibrant street life, therefore the project makes the city not only resilient, but also an even more interesting place. The adaptive character of urban environment can be best compared with a water park - some elements are used to transport water, others are used to store water, but they work as one system.Design of the Urban FabricUrbanismArchitecture and The Built Environmen
Nieuwe fusietoets scholen overbodig
No full textIn het basis- en voortgezet onderwijs zijn fusies aan de orde van de dag. Fusies die soms eindigen in megalomane grotestructuren. Om de fusiedrang te beteugelen, heeft het ministerie van OCW in 2011 een tamelijk bureaucratische fusietoetsingesteld. Die fusietoets wil de minister nu veranderen. Volgens Jos Blank en Thomas Niaounakis is die nieuwe toets een stap in de goede richting. Echter voor de grote risicovolle fusies is deze toets ineffectief en daardoor overbodig. Grote besturen opereren vaak al onder schaal nadelen. De minister kan beter heldere criteria opstellen om een duidelijke grens te trekken in plaats van de deur voor te grote structuren alsnog op een kier te zetten.Economics of Technology and Innovatio
