Exploiting tacit knowledge through knowledge management technologies
No full textThe purpose of this paper is to examine the contributions and suitability of the available knowledge management (KM) technologies, including the Web 2.0 for exploiting tacit knowledge. It proposes an integrated framework for extracting tacit knowledge in organisations, which includes Web 2.0 technologies, KM tools, organisational learning (OL) and Community of Practice (CoP). It reviews a comprehensive literature covering overview of KM theories, KM technologies and OL and identifies the current state of knowledge relating to tacit knowledge exploitation. The outcomes of the paper indicate that Internet and Web 2.0 technologies have stunning prospects for creating learning communities where tacit knowledge can be extracted from people. The author recommends that organisations should design procedures and embed them in their Web 2.0 collaborative platforms persuading employees to record their ideas and share them with other members. It is also recommended that no idea should be taken for granted in a learning community where tacit knowledge exploitation is pursued. It is envisaged that future research should adopt empirical approach involving Complex Adaptive Model for Tacit Knowledge Exploitation (CAMTaKE) and the Theory of Deferred Action in examining the effectiveness of KM technologies including Web 2.0 tools for tacit knowledge exploitation

Murphy; 1 ♂, 1 ♀ Northern Zambia, 40 km SE Mbala, S 09º09' E 31 º 27 ', 1565 m, 0 7.10. 2009, J. Lenz. The above paratypes are deposited in DNMNH and CUK. External characters. Frons smooth, covered by tightly appressed greyish-brown scales. Palpi brown, short, equal to eye diameter, straight, slightly pointed to apex. Antennae slender, light-brown. Thorax and tegulae lightgrey. Wingspan 12-14 mm (14 mm in the holotype). Forewing brownish-grey. Costal edge of first lobe light, with spots of dark scales. Base of bifurcation with small dark-brown spot, often weakly-developed. Fringes greyishbrown inside bifurcation. Hindwing uniform light-brown. Fringes also light-brown on all three lobes. Legs lightyellow. Male genitalia. Valvae asymmetrical. Harpe on left valva shorter than on right, broad in basal part then sharply arcuated at nearly right angle and directed posterad. Harpe on right valva long, сrescent-shaped. Uncus rather long, pointed at apex. Aedeagus long, stout, nearly straight. The distal part ends with a spine bearing a small pointed cornutus. Female genitalia. Papilla analis short, weakly developed. Ostium in shape of broad ring and positioned to right side. Distal part of sternum VIII with anterior apophyses with broad angular shape, left apophysis smaller than right. Posterior apophyses reduced. Diagnosis. External characters and genitalia of the new species are similar to Gypsochares londti Ustjuzhanin & Kovtunovich, 2010. However, the new species differs from the latter by shape of harpes. The new species has a long crescent-shaped right harpe, while Gypsochares londti has short spicular harpe. The two species also differ in the asymmetrical anterior apophyses of the female genitalia. Flight period: August—October, December, January. Distribution: Malawi, Zambia. Etymology. The new species is named in honour of the explorer of the entomofauna of Malawi, Raymond Murphy.Published as part of Kovtunovich, V., Ustjuzhanin, P. & Murphy, R., 2014, Plume moths of Malawi (Lepidoptera: Pterophoridae), pp. 451-494 in Zootaxa 3847 (4) on page 481, DOI: 10.11646/zootaxa.3847.4.1, http://zenodo.org/record/25005

Distinct and complementary functions of MDA5 and TLR3 in poly(I:C)-mediated activation of mouse NK cells.
No full textThe double-stranded RNA (dsRNA) analogue poly(I:C) is a promising adjuvant for cancer vaccines because it activates both dendritic cells (DCs) and natural killer (NK) cells, concurrently promoting adaptive and innate anticancer responses. Poly(I:C) acts through two dsRNA sensors, Toll-like receptor 3 (TLR3) and melanoma differentiation-associated protein-5 (MDA5). Here, we investigated the relative contributions of MDA5 and TLR3 to poly(I:C)-mediated NK cell activation using MDA5(-/-), TLR3(-/-), and MDA5(-/-)TLR3(-/-) mice. MDA5 was crucial for NK cell activation, whereas TLR3 had a minor impact most evident in the absence of MDA5. MDA5 and TLR3 activated NK cells indirectly through accessory cells and induced the distinct stimulatory cytokines interferon-alpha and interleukin-12, respectively. To identify the relevant accessory cells in vivo, we generated bone marrow chimeras between either wild-type (WT) and MDA5(-/-) or WT and TLR3(-/-) mice. Interestingly, multiple accessory cells were implicated, with MDA5 acting primarily in stromal cells and TLR3 predominantly in hematopoietic cells. Furthermore, poly(I:C)-mediated NK cell activation was not notably impaired in mice lacking CD8alpha DCs, providing further evidence that poly(I:C) acts through diverse accessory cells rather than solely through DCs. These results demonstrate distinct yet complementary roles for MDA5 and TLR3 in poly(I:C)-mediated NK cell activation
Tikuna bilineata Needham & Murphy, comb. n.
No full textTikuna bilineata (Needham & Murphy) comb. n. Choroterpes bilineata Needham & Murphy 1924: 48; Traver 1947: 156. The genus Tikuna was established by Savage et al. (2005) and Choroterpes atramentum Traver, 1947, was designated as the type species. Following this publication, two species from South and Central America remain incorrectly placed in Choroterpes. The first, Choroterpes bilineata Needham & Murphy, 1924, originally described from female imagos and male subimagos from La Chorrera, Putumayo Dist., Peru (now a part of Colombia), also belongs to the genus Tikuna, requiring the new combination Tikuna bilineata. The holotype and paratypes (Cornell University) were studied by one of us (H.M. Savage); additional specimens deposited at the U. S. National Museum of Natural History, Florida A&M University, and the Zoologische Sammlung des Bayerischen Staates were recorded from Brazil, Ecuador, Surinam, and Venezuela.

Onderzoek naar oorzaak schade dijkvak Westhoek - Zwarte Haan (km 13,000 - km 19,800) te Friesland
No full textIn 2004 is er schade geconstateerd aan de asfaltbekleding op de dijk tussen Westhoek en Zwarte Haan. Deze schade heeft zich in het afgelopen jaar progressief voortgezet. De asfaltdijkbekleding op de dijk tussen Westhoek en Zwarte Haan is aangelegd in 1972 - 1973. De lengte van het tracé bedraagt 6,8 km. De ligging van het onderzochte dijktraject (km 13,000 - 19,800) is in bijlage 1 weergegeven. De bekleding sluit aan de onderzijde aan op een bekleding van los gestorte klinkers die gepenetreerd zijn met asfaltmastiek. De bekleding heeft een dikte van circa 0,25 m en loopt in de onderste 2 m in een scheg naar een dikte van circa 0,50 m. Het asfaltbeton is aangelegd op een onderlaag van zand. Onder het zand bevindt zich de oorspronkelijke dijkkern van slecht doorlatende grond.Asfaltbekledinge
Investigation of Dempster Highway Sinkholes: km 82 and Two Moose Lake
No full textThis report presents the results of a project that aims to understand and, if possible, recommend actions to remediate the issues caused by the formation of sinkholes at km 82 and km 102-103 of the Dempster Highway. At km 82, this has resulted in sudden collapse of the
right-hand side driving surface of the highway. Major sinkholes have been repaired at this location on at least two occasions (June 2014 and Aug 2014) and the culvert at the site was replaced in October 2014. Undated photos suggest earlier sinkholes have formed at this location (SRK Consulting, 2014). Subsidence was also repaired in August 2015. At km 102-103, there has been general subsidence and sinkhole formation along the left-hand side of the road. Subsidence between km 102 and 103 has been regularly repaired as part of routine highway
maintenance and is therefore not documented. At this site, Two-Moose Lake is now encroaching on the road embankment.Repor
