Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

p53 convergently activates Dux/DUX4 in embryonic stem cells and in facioscapulohumeral muscular dystrophy cell models
No full textp53 activates Dux in mouse embryos and embryonic stem cells, as well as DUX4 in human facioscapulohumeral muscular dystrophy cell models.In mammalian embryos, proper zygotic genome activation (ZGA) underlies totipotent development. Double homeobox (DUX)-family factors participate in ZGA, and mouse Dux is required for forming cultured two-cell (2C)-like cells. Remarkably, in mouse embryonic stem cells, Dux is activated by the tumor suppressor p53, and Dux expression promotes differentiation into expanded-fate cell types. Long-read sequencing and assembly of the mouse Dux locus reveals its complex chromatin regulation including putative positive and negative feedback loops. We show that the p53-DUX/DUX4 regulatory axis is conserved in humans. Furthermore, we demonstrate that cells derived from patients with facioscapulohumeral muscular dystrophy (FSHD) activate human DUX4 during p53 signaling via a p53-binding site in a primate-specific subtelomeric long terminal repeat (LTR)10C element. In summary, our work shows that p53 activation convergently evolved to couple p53 to Dux/DUX4 activation in embryonic stem cells, embryos and cells from patients with FSHD, potentially uniting the developmental and disease regulation of DUX-family factors and identifying evidence-based therapeutic opportunities for FSHD.Molecular Technology and Informatics for Personalised Medicine and HealthFunctional Genomics of Muscle, Nerve and Brain Disorder
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
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

Comments. The distinguishing feature for B. dux is its distinct semi-circular ridge on the dorso-lateral propodeum. Baeus leai is the only other species to possess a similar structure. However, the two species are very different in many other characters, namely, the shape of the gena, sculpturing of the dorsal mesosomal, and smaller body and eye size. Baeus dux has been collected from south-eastern Queensland (Fig. 15A) and Philip Island near Norfolk Island. The habitats from which some specimens were collected include a suburban garden and a potato crop, indicating that the host(s) are tolerant of, or may prefer, heavily disturbed sites.Published as part of Stevens, N.

A process evaluation of the City of Cape Town Business Support Voucher Programme
No full textIncludes bibliographical references (leaves 74-78).This dissertation focuses on a process evaluation of the City of Cape Town (CoCT) Business Support Voucher Programme (BSVP) which assessed whether this programme was implemented as intended. The BSVP aims to provide access to quality business support services and products to entrepreneurs in order to empower them to develop and grow their businesses. The target beneficiaries of the BSVP are the over 35 year old age group (including women, youth and the disabled) who are potential or start-up entrepreneurs or who own/run existing small businesses. A service utilisation flow chart was used to review the services provided by the allocating agents and the business development service providers. Data providers included the project sponsors, the implementation agent, the allocating agents and a convenience sample of beneficiaries and service providers. Additional materials used included check lists during site visits and a review of records. The findings suggested that whilst the programme was largely implemented as planned, there could be improvements to the definition of the programme targets, the consistency of the implementation across the programme and putting monitoring and reporting systems in place. The dissertation includes selected recommendations for implementation improvement, sustainability and future outcomes and impacts

SAMA R 60725 adult male with nuptial pads and vocal slits, calling when collected, Yuwong Village, Huon Peninsula, Morobe Province, Papua New Guinea, (5 ° 51.263 'S, 146 ° 44.057 'E, ~ 400 m asl) collected by Stephen Richards on 13 th Jan 2003. Paratypes. UPNG 9986 adult male with nuptial pads and vocal slits, collected on 15 January 2003, SAMA R 60726, adult female with eggs, collected 16 January 2003, both with same collection data as holotype. Diagnosis Litoria dux sp. nov. can be distinguished from all congeners by the following combination of characters 1) green dorsal colouration 2) large adult size (two mature males with nuptial pads 67.0 and 70.3 mm, a female 75.0 mm SV) 3) prominent white dermal folds on the arms and legs 4) absence of white labial stripe 5) hands extensively webbed 6) iris red and white, without mottling or black pigmentation 7) sclera of eye black and 8) edge of upper eyelid lacking a white edge. Description of holotype Adult male with following measurements (mm) SVL 70.3; EN 6.7; HW 24.1; EYE 7.6; TL 37.7; IN 6.2; HL 24.4; EAR 4.5; 4 TD 4.6; 4 TP 3.7; 3 FD 5.4; 3 FP 3.4. Habitus moderately slender; head marginally wider than long (HW/HL 1.029), not wider than body in dorsal view; snout truncate in dorsal and lateral view; labial region slightly flared; loreal region steeply sloping, marginally concave; canthus rostralis moderately distinct, curved; nares much closer to tip of snout than to eyes, oriented laterally and only marginally visible in both dorsal and anterior views. Choanae large, roughly circular, separated by a distance approximately three times their width; prominent clumps of about ten very low triangular vomerine teeth positioned along the posterior ridge of two triangular, posteriorly directed elevations located medially to choanae. Eyes moderately small but prominent (EYE/SVL 0.108), clearly visible in both dorsal and lateral views, pupil horizontal, thin band of dense small white pigment flecks extends across dorsal edge of nictitating membrane, very sparse scattered pigment flecks elsewhere on membrane, especially around anterior corner. Tympanum moderate (E AR/SVL 0.046), annulus distinct, dorsal edge obscured by thick, fleshy, curved supratympanic fold that runs from posterior edge of eye to axillary junction. In preservative skin on dorsal surfaces of body and limbs smooth; ventrally throat, forelimbs and most of hindlimbs smooth, abdomen and lateral edge of femur coarsely granular. Arms robust; prominent white dermal fold extends from penultimate phalanx of finger IV along upper arm to elbow; relative lengths of fingers III>IV>II>I; terminal discs of all fingers significantly wider than penultimate phalanx (3 FP/ 3 FD 0.630), with circummarginal grooves; subarticular tubercles prominent, conical; two tubercles on digits I and II, three tubercles (medial tubercle distinctly larger) on digits III and IV; one rounded supranumerary tubercle on digit I, three or more on digits II to IV; a single large (one third length of digit I), ovoid inner metacarpal tubercle and a small rounded nuptial excresence at base of digit I. All digits webbed, webbing extends to level of proximal subarticular tubercle between digits I and II, and on both sides of digit III; and to disc on outer side of digit two and inner side of digit IV. Legs moderately long (TL/SVL = 0.537); prominent white dermal fold along tarsus extends from lateral edge of toe V to heel. Relative lengths of toes IV>V>III>II> 1; discs expanded, with circummarginal grooves (4 TP/ 4 TD = 0.804), subarticular tubercles prominent, rounded or conical, two tubercles on digits I and II, three on digits III and V, and four on digit IV; numerous small round supranumerary tubercles on basal phalanges of digits IIV; inner metatarsal tubercle small, oval shaped. All digits webbed, webbing extends halfway along penultimate phalanx on both sides of digit IV, and to base of disc on all other digits. In life dorsum and dorsal surfaces of arms and legs pale leaf green with scattered faint patches of yellowish green. Ventral surfaces, including hidden surfaces of both limbs, yellow to yellowish white. Yellowishgreen horseshoe shaped marking on the tympanic membrane. Dorsal surfaces of outer toes and fingers leaf green; of inner toes and webbing yellow. Prominent offwhite dermal ridges on outer edge of arms and legs. Pupil horizontal, iris with distinctive outer red rim surrounding inner ring of grey around pupil, a further thin reddish line is present just above the pupil; sclera black. In preservative dorsal surfaces pale slate blue with widely scattered very small patches of darker slate blue; ventral surfaces offwhite, abdomen with very slight brownish tinge. Dorsal surface of legs, lower arms, finger IV and toe V largely slate blue. Remaining digits largely white with varying levels of faint brown spotting, especially toe IV and finger III which appear faintly tinted with brown. Tympanic membrane with distinct area of clear skin in the shape of an inverted horseshoe. Dermal ridge on edge of legs and arms white. Nuptial excresence very faint brown. Va r i a t i o n The type series is rather uniform. The male UPNG 9986 is the smallest specimen and is significantly darker than the other types, especially in the anterior dorsal region. The single female paratype (SAMA R 60726) is the largest specimen (SVL 75.0 mm) but this size difference is not unusual for Litoria species (e.g, Tyler 1968). Both paratypes have slightly more brown spotting on the hands and feet than the holotype. Comparison with other species Litoria dux differs from all New Guinean Litoria except L. graminea and L. sauroni in the characters used to diagnose L. graminea (above). It differs from L. graminea in having a narrower head (0.34 Vs 0.380.40), an iris without extensive black and orange reticulations and in having a small round (vs elongate) nuptial pad. It is most similar to L. sauroni but differs notably in a number of characters related to eye colouration, including iris without extensive and heavy black and red pigmentation, sclera black (vs blue), and pigment flecking largely restricted to a band across the dorsal edge of the nictitating membrane (vs dense stippling across membrane). It can also be distinguished from both the species mentioned above by the absence of a white distal edge to the upper eyelid. Etymology From the Latin dux, meaning leader, alluding to the bright colouration and impressive appearance of the species (particularly the red iris) which make it prominent within a genus that is already replete with spectacular species. Natural history Litoria dux were calling from high in the canopy on ridges adjacent to the Tarona River during January 2003. One specimen was in a tree adjacent to a forest garden and two specimens were collected from primary rainforest in trees overhanging puddles that had formed in a previously dry rocky creek bed after torrential rain. One male descended to within three metres of the pools during observation, suggesting that this species may breed in pools on the forest floor. Descending to the ground after torrential rain to breed is a behaviour typical of several groups of unrelated tropical arboreal frogs e.g Rhacophorus (Inger & Stuebing 1997) and Agalychnis (Savage 2002)). Female specimens for all L.graminea complex species are very rarely collected. SAMA R 60726 is larger than the two male L. dux, and contains small, pigmented eggs. FIGURE 9. Advertisement calls of A.
