The 9th meeting of the African Society of Human Genetics, in partnership with the Senegalese Cancer Research and Study Group and the Human Heredity and Health in Africa (H3Africa) Consortium, was held in Dakar, Senegal. The theme was Strengthening Human Genetics Research in Africa. The 210 delegates came from 21 African countries and from France, Switzerland, UK, UAE, Canada and the USA. The goal was to highlight genetic and genomic science across the African continent with the ultimate goal of improving the health of Africans and those across the globe, and to promote the careers of young African scientists in the field. A session on the sustainability of genomic research in Africa brought to light innovative and practical approaches to supporting research in resource-limited settings and the importance of promoting genetics in academic, research funding, governmental and private sectors. This meeting led to the formation of the Senegalese Society for Human Genetics.

We documented one of the most species-rich assemblages of tropical rain-forest Auchenorrhyncha, comprising 402 phloem- and xylem-feeding species, by sampling adults from forest vegetation. Further, we reared 106 species from larvae sampled on 14 plant species. Both xylem- and phloem-feeding guilds exhibited wide host-plant ranges, as 74% of species fed on more than one plant family. In comparison, using data extracted from the temperate-zone literature, phloem-feeders exhibited lower host specificity in Papua New Guinea than in Germany, because in Papua New Guinea they were dominated by generalist Fulgoroidea while in Germany by specialist Membracoidea. The similarity of Auchenorrhyncha assemblages from different plant species was unrelated to the phylogenetic distance between their hosts. Host specificity, abundance and species composition of Auchenorrhyncha assemblages were unrelated to the optimum of their host plant species on succession gradient from secondary to primary forest. Higher host specificity did not lead to greater species richness in Auchenorrhyncha assemblages feeding on different plant species, but the number of species feeding on a particular plant species was a strong predictor of the Auchenorrhyncha abundance on that plant. These patterns suggest that Auchenorrhyncha assemblages on these plant species are not saturated with species and determined by division of limited resources among competitors, but instead are dependent on the number of colonizers from the regional species pool.

This article provides a comprehensive theoretical model for analysing the influence of European party federations (Europarties) on their Central and Eastern European (CEE) partner parties. It draws on the concepts of Europeanization and party change and is, in principle, applicable to similar processes of party enlargement elsewhere. In the process of their Eastern enlargement, Europarties have searched for suitable CEE partner parties on which they have tried to exert influence. Thus far, little is known about the precise mechanisms involved and the actual impact of these processes. We argue that Europarty influence leads to party change on the side of the CEE partners, which brings about ‘West-Europeanization’. Europarties are expected to apply a double strategy that consists of a process of political exchange based on a largely asymmetric power relationship in favour of Europarties and a socialization strategy in which Europarties try to socialize their partners and convince them of the appropriateness of change. We present the theoretical and analytical tools for the analysis of the arguably largest extension of transnational party organizations, which provides ample testing ground for more general theories on party change. Furthermore, we present preliminary empirical evidence on the two most important cases, namely the European People's Party and the Party of European Socialists, which indicates that Europarties played an important role in the development of CEE parties and party systems in general.

This study examines associations between quality of life and multiple indicators of socio-economic position among people aged 50 or more years in 10 European countries, and analyses whether the relative importance of the socio-economic measures vary by age. The data are from the Survey of Health, Ageing and Retirement in Europe (SHARE) in 2004. 15,080 cases were analysed. Quality of life was measured by a short version of the CASP-19 questionnaire, which represents quality of life as comprising four conceptual domains of individual needs that are particularly relevant in later life: control (C), autonomy (A), self-realisation (S) and pleasure (P). The short version has 12 items (three for each domain). Five indicators of socio-economic position were used: income, education, home ownership, net worth, and car ownership. A multiple logistic regression showed that quality of life was associated with socio-economic position, but that the associations varied by country. Relatively small socio-economic differences in quality of life were observed for Switzerland, but comparatively large differences in Germany. Education, income, net worth, and car ownership consistently related to quality of life, but the association of home ownership was less consistent. There was no indication that the socio-economic differences in quality of life diminished after retirement (i.e. from 65+ years). Conventional measures of socio-economic position (education and income), as well as alternative indicators (car ownership and household net worth), usefully identified the differential risks of poor quality of life among older people before and after the conventional retirement age.

A lower bound on the number of points that can be placed in a square of side $\sigma$ such that no two points are within unit distance from each other is proven. The result is constructive, and the series of packings obtained contains many conjecturally optimal packings.

Par le fait que nous ne dépouillons qu'une fois par trimestre el en vue du Bulletin international les périodiques qui nous arrivent da toutes parts, ce n'est que ces jours derniers que nous avons appris le bel anniversaire que vous avez célébré le mois passé, et nous regrettons de ne l'avoir pas su plus tôt pour nous associer à temps aux nombreux témoignages d'estime et de reconnaissance qui vous out été exprimés de tous côtés.
