Formal and Informal Seed Systems in Kenya: Supporting Indigenous Vegetable Seed Quality

Indigenous vegetables play an important role in Kenyan food security, but production is limited by poor seed quality. Traditionally, seeds have been traded through informal networks, but a new formal seed sector is emerging. This study assessed the relative potential for formal or informal seed systems to meet the need for high-quality indigenous vegetable seed. By evaluating determinants of farmers’ seed purchasing behaviour, we conclude that informal seed systems have greater potential to meet this need and should be strengthened. This study suggests that policy-makers should use context-specific data to guide decisions on seed policy.     

Correlates of Childhood vs. Adolescence Internalizing Symptomatology from Infancy to Young Adulthood

In light of its associations with child and adolescent health and well-being, there remains a need to better understand the etiological underpinnings and developmental course of internalizing symptomatology in children and adolescents. This study leveraged intensive longitudinal data (N?=?959; 49.6?% females) to test the hypothesis that internalizing symptoms in childhood may be driven more strongly by family experiences whereas internalizing symptoms in adolescence may derive more uniquely from familial loading for affective disorders (i.e., maternal depression). We evaluated the relative contributions of (a) family experiences (b) maternal depression, and (c) peer influences in testing this hypothesis. The results indicated that family predictors were more strongly correlated with childhood (relative to adolescent) internalizing symptoms. In contrast to previous findings, maternal depression also exhibited stronger associations with childhood internalizing symptoms. Although often overlooked in theories concerning potential differential origins of childhood vs. adolescent internalizing symptomatology, peer experiences explained unique variation in both childhood and adolescent internalizing problems.     

drones,swarms and becoming-insect: feminist utopias and posthuman politics

Insects and ‘the swarm’ as metaphors and objects of research have inspired works in the genres of science fiction and horror; social and political theorists; and the development of war-fighting technologies such as ‘drone swarms’, which function as robot/insect hybrids. Contemporary developments suggest that the future of warfare will not be ‘robots’ as technological, individualised substitutions for idealised (masculine) warfighters, but warfighters understood as swarms: insect metaphors for non-centrally organised problem-solvers that will become technologies of racialisation. As such, contemporary feminist analysis requires an analysis of the politics of life and death in the insect and the swarm, which, following Braidotti (2002), cannot be assumed to be a mere metaphor or representation of political life, but an animating materialist logic. The swarm is not only a metaphor but also a central mode of biopolitical and necropolitical war, with the ‘terrorist’ enemy represented as swarm-like as well. In analysing the relations of assemblage and antagonism in the war ontologies of the drone swarm, I seek inspiration from what Hayles (1999, p. 47) describes as a double vision that ‘looks simultaneously at the power of simulation and at the materialities that produce it’. I discuss various representations and manifestations of swarms and insect life in science/speculative fiction, from various presentations of the ‘Borg’ in Star Trek (1987–1994, 1995–2001, 1996), Alien (1979) and The Fly (1958, 1986) to more positive representations of the ‘becoming-insect’ as possible feminist utopia in Gilman’s Herland (2015 [1915]) and Tiptree’s Houston, Houston, Do You Read? (1989 [1976]). Posthuman warfare also contains the possibilities of both appropriating and rewriting antagonisms of masculine and feminine in the embodiment of the subject of war in the swarm. This piece seeks to analyse new ways of feminist theorising of the relations of power and violence in the embodiment of war as the swarm.     

Identifying Spatial Efficiency–Equity Trade-offs in Territorial Development Policies: Evidence from Uganda

Abstract

We contribute to the debate on the spatial allocation of infrastructure investments by examining where these investments generate the highest economic return (‘spatial efficiency’), and identifying trade-offs when infrastructure coverage is made more equitable across regions (‘spatial equity’). We estimate models of firm location choice in Uganda, drawing on insights from the new economic geography literature. The main findings show that manufacturing firms gain from being in areas that offer a diverse mix of economic activities. Public infrastructure investments in other locations are likely to attract fewer private investors, and will pose a spatial efficiency–equity trade-off.
