Informalilty in the Social and Culture Life in the City Centre of Nairobi

We live in a world of advanced technology, stiff global competition and rapid transformation of all facets of life and as a result architecture has not been spared. These transformations affect the social relations, cultural consumption and political economy that have influenced the manner in which people perform in and out of space in the city centres. The residents have adopted strategies for negotiating through the spaces sanitized by authorities and other agents. The public spaces provide the background materials for informal urban practices that are sometimes deemed illegal yet are necessary for animating the city spaces. Cities market themselves ecstatically beyond the baroque with a more visible presence of the contending parties through trademarks, public relations invasively advertised in streets, monuments (signature buildings or projects), and language. This paper comes out of a research carried out in Nairobi in February and March 2007. It examined how the notions of globalisation are reflected in the life in the city centre; the impacts on the quality of life of users of the city centre and how informal urbanism has developed as copying strategy to deal with the transformations due to liberalization and globalization.

Contact and Culture: Mechanisms of Reconciliation in Northern Ireland and Israel

In Northern Ireland and Israel schools have long been recognised as key sites for addressing the problems of poor intergroup relations (see Dunn, 1990; Murray, 1985). The developments of integrated schools which welcome members of the main communities have been regarded as a key development which is likely to be instrumental in promoting more harmonious relations. Although the schools have been regarded in the media as a ‘good news story’ the qualitative processes through which teachers within these schools foster reconciliation is not always clear. The purpose of this chapter is thus to explore this question by drawing on contact theory and interviews with teachers in Northern Ireland and Israel.

A fish bradykinin (Arg0; Trp5; Leu8-bradykinin) from the defensive skin secretion of the European edible frog; Pelophylax kl. esculentus: structural characterization; molecular cloning of skin kininogen cDNA and pharmacological effects on mammalian smooth muscle

Extensive studies on bradykinin-related peptides (BRPs) generated from plasma kininogens in representative species of various vertebrate taxa, have confirmed that many amphibian skin BRPs reflect those present in putative vertebrate predators. For example, the (Val1, Thr6)-bradykinin, present in the defensive skin secretions of many ranids and phyllomedusines, can be generated from plasma kininogens in colubrid snakes - common predators of these frogs. Here, we report the presence of (Arg0, Trp5, Leu8)-bradykinin in the skin secretion of the European edible frog, Pelophylax kl. esculentus, and have found it to be encoded in single copy by a kininogen with an open-reading frame of 68 amino acid residues. This peptide is the archetypal bony fish bradykinin that has been generated from plasma kininogens of the bowfin (Amia calva), the long-nosed gar (Lepisosteus oseus) and the rainbow trout (Onchorhynchus mykiss). More recently, this peptide has been shown to be encoded within cloned kininogens of the Atlantic cod (Gadus morhua) spotted wolf-fish (Anarichas minor), zebrafish (Danio rerio), pufferfish (Tetraodon nigroviridis) and Northern pike (Esox lucius). The latter species is regarded as a major predator of P. kl. esculentus. Synthetic (Arg0, Trp5, Leu8)-bradykinin was previously reported as having multiphasic effects on arterial blood pressure in conscious trout and here we have demonstrated that it can antagonize the relaxation in rat arterial smooth muscle induced by canonical mammalian bradykinin. The discovery of (Arg0, Trp5, Leu8)-bradykinin in the defensive skin secretion of this amphibian completes the spectrum of vertebrate taxon-specific BRPs identified from this source.
