Farmer-to-farmer extension: opportunities for enhancing performance of volunteer farmer trainers in Kenya

Farmer-to-farmer extension (FFE) is playing a complementary role to formal extension services in facilitating the spread of agricultural technologies and improving farmers’ capacities. The effectiveness and sustainability of such programmes depend on volunteer farmer trainers (VFTs) having technical skills and overcoming process-related challenges that hinder them from achieving the desired outcomes. This article uses quantitative and qualitative data collected from seven sites to explore the challenges experienced by VFTs as they share their knowledge on livestock feed innovations in a dairy development project in Kenya. Sustainable opportunities for enhancing VFTs’ performance are discussed.

Theorien mittlerer Reichweite

Merton’s concept of “middle range theories” has been widely accepted as one of his most influential contributions to sociological terminology, even if there is no conclusive understanding of its semantic and methodological meaning. The article proposes to ignore the term. On the one hand, it cannot be logically clarified and, on the other, it restrains an appropriate judgement of the merits of Merton’s research programme.     

Population genetic data of 15 tetrameric short tandem repeats (STRs) in Berbers from Morocco

The allele frequency distribution of 15 short tandem repeats (STR) loci contained in the AmpFlSTR Identifiler PCR Amplification Kit (Applied Biosystems), was determined in two Berber populations from Asni and Bouhria, in Central and Eastern Morocco, respectively. A total of 209 individuals were typed. No deviations from the Hardy-Weinberg equilibrium were observed for Asni at the 15 STRs loci whereas for the Bouhria samples, two loci (D5S818 and TH01) showed significant departures from Hardy-Weinberg expectations (after Bonferroni's correction). All loci are highly polymorphic and population differentiation tests showed that the Moroccan samples from Asni and Bouhria have significant differences in 4 out of 15 loci (D21S11, D7S820, D16S539 and TPOX). The aim of the study was to obtain accurate allele frequencies relevant for forensic applications. Comparative analyses between our population data and other population samples gathered from the literature are also presented.
