African language books for children: issues for authors

Growing interest in bilingual education in sub-Saharan Africa has highlighted an urgent need for reading material in African languages. In this paper, we focus on authors, one of several groups of stakeholders with responsibility for meeting this demand. We address three main issues: the nature and extent of African language publishing for children; the challenges for authors; and the available support. Our analysis is based on interviews and focus group discussions with publishers, authors, translators, educationalists, and representatives of book promotion organisations from nine African countries and documentary data on children's books in African languages in South Africa. Although there is evidence of a growing interest in producing books in local languages, the number of titles is constrained by funding. The challenges for authors include the need to understand the ingredients for successful children's books and for the sensitivity necessary to negotiate the linguistic challenges associated with a newly emergent genre in African languages. Support, in the form of competitions and workshops, relies on external funding and expertise and offers only temporary solutions. We finish with suggestions for more sustainable ways forward.

Multiscale evolving complex network model of functional connectivity in neuronal cultures

Cultures of cortical neurons grown on multielectrode arrays exhibit spontaneous, robust and recurrent patterns of highly synchronous activity called bursts. These bursts play a crucial role in the development and topological selforganization of neuronal networks. Thus, understanding the evolution of synchrony within these bursts could give insight into network growth and the functional processes involved in learning and memory. Functional connectivity networks can be constructed by observing patterns of synchrony that evolve during bursts. To capture this evolution, a modelling approach is adopted using a framework of emergent evolving complex networks and, through taking advantage of the multiple time scales of the system, aims to show the importance of sequential and ordered synchronization in network function.

Investigating the phytotoxicity of the graminicide fluazifop-P-butyl against native UK wildflower species

BACKGROUND: The selective graminicide fluazifop-P-butyl is used for the control of grass weeds in dicotyledonous crops, and commonly applied in amenity areas to reduce grass productivity and promote wildflower establishment. However, evidence suggests that fluazifop-P-butylmight also have phytotoxic effects on somenon-target plants. This study investigates the effects of fluazifop-P-butyl on the emergence, phytotoxicity and above-ground biomass of nine perennial wildflower species and two grass species, following pre- and post-emergent applications at half, full and double label rates in a series of glasshouse experiments. RESULTS: While pre- and post-emergent applications of fluazifop-P-butyl caused reductions in seedling emergence and increased phytotoxicity on native wildflower and grass species, these effects were temporary for the majority of wildflower species tested, and generally only occurred at the double application rate. No differences in biomass were observed at any of the rates, suggesting good selectivity and no long-term effects of fluazifop-P-butyl application on the wildflower species from either pre-emergent or post-emergent applications. CONCLUSION: These results have direct relevance to the management of amenity areas for biodiversity, as they confirm the suitability of these wildflower species for inclusion in seed mixtures where fluazifop-P-butyl is to be applied to control grass productivity.

The functional neuroanatomy of the evolving parent-infant relationship

Infant survival and the development of secure and cooperative relationships are central to the future of the species. In humans, this relies heavily on the evolving early parent–infant social and affective relationship. While much is known about the behavioural and psychological components of this relationship, relatively little is known about the underlying functional neuroanatomy. Affective and social neuroscience has helped to describe the main adult brain networks involved, but has so far engaged very little with developmental findings. In this review, we seek to highlight future avenues for research by providing a coherent framework for describing the parent–infant relationship over the first 18 months. We provide an outline of the evolving nature of the relationship, starting with basic orienting and recognition processes, and culminating in the infant's attainment of higher socio-emotional and cognitive capacities. Key social and affective interactions, such as communication, cooperative play and the establishment of specific attachments propel the development of the parent–infant relationship. We summarise our current knowledge of the developing infant brain in terms of structure and function, and how these relate to the emergent abilities necessary for the formation of a secure and cooperative relationship with parents or other caregivers. Important roles have been found for brain regions including the orbitofrontal, cingulate, and insular cortices in parent–infant interactions, but it has become clear that much more information is needed about the developmental time course and connectivity of these regions.

Letter processing and font information during reading: beyond distinctiveness, where vision meets design

Letter identification is a critical front end of the reading process. In general, conceptualizations of the identification process have emphasized arbitrary sets of distinctive features. However, a richer view of letter processing incorporates principles from the field of type design, including an emphasis on uniformities across letters within a font. The importance of uniformities is supported by a small body of research indicating that consistency of font increases letter identification efficiency. We review design concepts and the relevant literature, with the goal of stimulating further thinking about letter processing during reading.

What An Collins was reading

An Collins’s 1653 collection of poems, Divine Songs and Meditacions, contain all that we know about the writer. But in these poems she tells us much about the books that she had read, and about her indebtedness to the catechetical works of the Elizabethan puritan theologian William Perkins in particular.
