Nurturing lifelong learning in communities through the National University of Lesotho: prospects and challenges

This paper analyses one aspect of a pan-African action research project called ITMUA (Implementing the Third Mission of Universities in Africa). This particular paper draws on the data from that project to explore the National University of Lesotho’s contribution to lifelong learning in its communities. It provides background information on the ITMUA initiative and analyses interview and focus group responses to two case studies in terms of their contribution to lifelong learning. It uses, as its analytical framework, a modified version of Mbigi’s African perspective on the four De Lors’ ‘pillars’, by adding a fifth pillar, courtesy of Torres. The paper argues that community engagement is a two-way process between universities and their wider constituencies with opportunities for mutual lifelong learning. But there are also challenges of understanding and process which must be addressed if the full range of these lifelong learning pillars is to be accommodated within African contexts. The paper provides an introduction to the history of community engagement in Africa as a university mission, followed by a brief discussion of lifelong learning within African perspectives. After describing the particular context of Lesotho, the concept of community service and community engagement in contemporary African contexts introduces the action research project and the case studies. The final part of the paper presents and discusses the research findings

Mutations in TITF-1 are associated with benign hereditary chorea

Benign hereditary chorea (BHC) (MIM 118700) is an autosomal dominant movement disorder. The early onset of symptoms (usually before the age of 5 years) and the observation that in some BHC families the symptoms tend to decrease in adulthood suggests that the disorder results from a developmental disturbance of the brain. In contrast to Huntington disease (MIM 143100), BHC is non-progressive and patients have normal or slightly below normal intelligence. There is considerable inter- and intrafamilial variability, including dysarthria, axial dystonia and gait disturbances. Previously, we identified a locus for BHC on chromosome 14 and subsequently identified additional independent families linked to the same locus. Recombination analysis of all chromosome 14-linked families resulted initially in a reduction of the critical interval for the BHC gene to 8.4 cM between markers D14S49 and D14S278. More detailed analysis of the critical region in a small BHC family revealed a de novo deletion of 1.2 Mb harboring the TITF-1 gene, a homeodomain-containing transcription factor essential for the organogenesis of the lung, thyroid and the basal ganglia. Here we report evidence that mutations in TITF-1 are associated with BHC

Clinical and genetic heterogeneity in benign hereditary chorea.

Item does not contain fulltextBACKGROUND: Benign hereditary chorea (BHC) is an autosomal dominant disorder that can be distinguished from Huntington disease by its early onset, stable or only slightly progressive course, and absence of mental deterioration. The variation in clinical features is such that its very existence has been doubted. The authors recently described the localization of a gene responsible for BHC on chromosome 14q in a large Dutch family. OBJECTIVE: To report results of extensive clinical and linkage analyses for this Dutch family and six other families with BHC. RESULTS: Three of the seven families had linkage to a region on chromosome 14q13.1-q21.1. HOMOG analysis showed odds of 10 x 10(11) in favor of locus heterogeneity. Haplotype analyses for the linked families resulted in a reduction of the critical interval for the BHC gene to 8.4 cM between marker D14S49 and marker D14S278. Clinically, these three families had a homogeneous picture with early-onset chorea, sometimes accompanied by slight ataxia in walking, but without dystonia, myoclonic jerks, or dysarthria. The severity of the choreatic movements tended to abate in adolescence or early adulthood. In the unlinked families, symptoms and signs were more heterogeneous as to age at onset and the occurrence of myoclonic jerks or dystonia. CONCLUSIONS: BHC is a clinically and genetically heterogeneous disorder, with one well-defined clinical syndrome mapping to chromosome 14q

The use of chemical and visual cues in female choice in the butterfly Bicyclus anynana

Investigating the relative importance of multiple cues for mate choice within a species may highlight possible mechanisms that led to the diversification of closely related species in the past. Here, we investigate the importance of close-range pheromones produced by male Bicyclus anynana butterflies and determine the relative importance of these chemical cues versus visual cues in sexual selection by female choice. We first blocked putative androconial organs on the fore- and hindwings of males, while also manipulating the ability of females to perceive chemical signals via their antenna. We found that male chemical signals were emitted by both fore- and hindwing pairs and that they play an important role in female choice. We subsequently tested the relative importance of these chemical cues versus visual cues, previously identified for this species, and found that they play an equally important role in female choice in our laboratory setting. In addition, females will mate with males with only one signal present and blocking both androconial organs on males seems to interfere with male to male recognition. We discuss the possible functions of these signals and how this bimodal system may be used in intra- and interspecific mate evaluation

Did globalisation aid industrial development in colonial India? A study of knowledge transfer in the iron industry

The article explores the link between international economic integration and technological capability in colonial India. The example of the iron industry shows that many new ideas and skills flowed into India from Europe, but not all met with commercial success. The essay suggests a reason why. In those fields in which the costs of complementary factors were relatively low, the chance of success was higher. This condition was present in the craft of the blacksmith, in which the main complementary input was abundant craftsmanship. The condition was slow to develop in iron-smelting, where the costs of fuel, labour, capital and carriage of ore were initially high
