Time trends in the prevalence of peanut allergy: three cohorts of children from the same geographical location in the UK.
No full textBackground: This article investigated the prevalence of peanut allergy in three cohorts of children born in the same geographical location, Isle of Wight, UK and seeks to determine whether the prevalence of peanut allergy has changed between 1994 and 2004. Methods: Three cohorts of children (age 3-4 years) born on the Isle of Wight, were assessed for peanut allergy and the outcomes compared: Cohort A: Born in 1989; reviewed at 4 years of age (n = 2181). Cohort B: Born between 1994 and 1996; reviewed between 3 and 4 years of age (n = 1273). Cohort C: Born between 2001 and 2002; reviewed at 3 years of age (n = 891). Results: Peanut sensitization increased significantly from 1.3% in Cohort A to 3.3% (P = 0.003) in Cohort B before falling back to 2.0% in Cohort C (P = 0.145). Similarly, clinical peanut allergy increased significantly from 0.5% in Cohort A to 1.4% (P = 0.023) in Cohort B, with a subsequent fall to 1.2% in Cohort C (P = 0.850). Conclusions: Our data from three cohorts of 3- to 4-year-old children born in the same geographical area shows that peanut allergy prevalence has changed over time. Peanut sensitization and reported allergy in children born in 1994-1996 increased from 1989 but seems to have stabilized or slightly decreased since the late 1990s, although not significant

Raphionacme chimanimaniana (Periplocaceae), a new species from Zimbabwe
No full textRaphionacme chimanimaniana Venter & Verhoeven, a new species from Zimbabwe is described. It is recognized by its erect stems, linear-lanceolate leaves which are hirsute and glandular, few-flowered inflorescences and magenta to white flowers. Plants inhabit scrubby veld at high altitude in the Chimanimani Mountains. R. chimanimaniana resembles R. brownii Scott Elliot and R. pulchella Venter & Verhoeven. All three species erect with linear leaves and white to purple flowers. R. chimanimaniana is distinguished from R. brownii and R. pulchella by the few-flowered inflorescences with large flowers, its columnar corona bases and glandular hirsute indumentum
Raphionacme moyalicus (Periplocaceae), a new species from Kenya
No full textRaphionacme moyalicus Venter & R.L. Verh., a new species from Moyale, Northern Frontier Province, Kenya, is described and figured. A map with its known distribution is also provided. R. moyalicus shows affinity with R. michelii De Wild., R. borenensis Venter & M.G. Gilbert and R. arabica A,G. Mill. & Biagi. These species all have in common filiform corona lobes and stamens with fleshy, laterally dilated filament bases. All are erect to spreading, single- or few-stemmed, geophytic herbs. R. moyalicus is distinguished by its long corona lobes, twice as long as the corolla lobes, the small flowers and the dense, scaberulous indumentum
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
Raphionacme elsana (Periplocaceae), a new species from Natal, South Africa
No full textRaphionacme elsana Venter & Verhoeven, a new species from northern Zululand, in Natal, is described and illustrated, and a map showing its known distribution is provided. R. elsana appears to be closely related to R. velutina Schltr. and is vegetatively identical; however, in its bicoloured corona with green lateral segments and the central segment of the lobes much broadened at the base and deep violet in colour, the new species is easily distinguished when in flower, while in fruit it differs significantly in its keel-shaped, much shorter and stout follicles (in R. velutina very narrowly ovoid). In this latter character R. elsana appears also to be related to R. madiensis S. Moore, from Central Africa, and R. namibiana Venter & Verhoeven, from South West Africa/Namibia
"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.
