A Cortical Region Consisting Entirely of Face-Selective Cells

Face perception is a skill crucial to primates. In both humans and macaque monkeys, functional magnetic resonance imaging (fMRI) reveals a system of cortical regions that show increased blood flow when the subject views images of faces, compared with images of objects. However, the stimulus selectivity of single neurons within these fMRI-identified regions has not been studied. We used fMRI to identify and target the largest face-selective region in two macaques for single-unit recording. Almost all (97%) of the visually responsive neurons in this region were strongly face selective, indicating that a dedicated cortical area exists to support face processing in the macaque

Exploring Prosopis Management and Policy Options in the Greater Horn of Africa: Proceedings of a Regional Conference, Addis Ababa, November 2014

Prosopis and the challenge itis posing has become a serious issue in most IGAD countries, affecting the livelihoods of farmers, agro-pastoral and pastoral communities. It has taken over farmland, browse and pasture, as well as reduced the water supply for people and for livestock in affected areas. Some governments have opted for expensive physical eradication methods which, however, are not proving effective. Others are trying alternative approaches which consider Prosopis an underutilised resource, rather than just an ecological menace

Hard, soft and thin governance spaces in land-use change: comparing office-to-residential conversions in England, Scotland and the Netherlands

In recent years, converting office buildings to residential use became a high-profile issue in the UK and in the Netherlands. There has, however, been differentiation in the policy response between England and Scotland (planning policy being devolved within the UK), and the Netherlands. We conceptualize this differentiation through the lens of variegated neoliberalism in the forms of hard, soft and thin governance spaces. England, where planning deregulation is more strongly adopted, represents a thin governance space. Scotland, where there has been little policy change, illustrates a hard governance space. The Netherlands represents a soft governance space, where proactive partnerships between government and developers predominate. This paper characterizes these distinct governance spaces and explores their impact on housing delivery and place-making, and the impact of underlying ideologies and planning culture(s) in governing office-to-residential conversions in the three countries. Drawing on national government assessments and statistics, interviews with stakeholders, and case study data from three cities: Leeds, Glasgow and Rotterdam, we conclude that while both hard and soft governance spaces, to different degrees and with different merits, are environments that enable planning, thin governance spaces – being driven more by ideology than notions of good governance – imply weak planning and place-making

Who gave whom hemoglobin S: The use of restriction site haplotype variation for the interpretation of the evolution of the Β S -globin gene

The hypothesis that three separate mutations to the Β S -globin gene have occurred in Africa in challenged. The distributions of the Β S and other Β-globin haplotypes and a simulation of the diffusion of the Β S gene are presented and argued to be more in accord with the rapid diffusion of a single mutant that by recombination and gene conversion now occurs on several different haplotypes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38540/1/1310010309_ftp.pd

Genetic drift and polygenic inheritance

The interaction of random gene drift and selection was studied by computer simulation for two quantitative traits, which were considered to approximate stature and skin color differences in human populations. The expected effects of gene drift, fixation of alleles and reduction of genotypic and phenotypic variances, were found in the simulation. Stabilizing selection, which seems to be the type of selection operating on these traits, was found to increase the effects of gene drift. Since there seems to be no evidence of reduction in phenotypic and presumably genotypic variability in small human populations, the applicability of these simple genetic models to human traits raises problems for which several possible solutions exist.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37525/1/1330370115_ftp.pd
