Improving the Quality of Women’s Gold in Mali, West Africa: The Case of Shea
No full textThe collection, primary processing, and subsequent sale of shea-based products make an important contribution to rural women’s cash income in many of Mali’s shea producing areas. Internationally, shea has recently become popular in high-valued cosmetics thanks to its therapeutic properties— a deviation away from its historic use as a cheap cocoa-butter substitute. For these reasons, international development actors have targeted the Malian shea value chain as part of their private-sector-development and rural-poverty-alleviation programs and strategies. Information asymmetry in the production and marketing of shea has led to a “Market for Lemons” scenario much like that described by Akerlof (1970), thereby compromising the subsector’s potential to serve as a powerful source of rural income growth and poverty alleviation. A combination of tools is used to describe the Malian shea value chain, including the “Structure, Conduct, Performance” framework borrowed from the industrial organization literature and the “Subsector Studies” approach popular in current export-led international development strategies. Analogies from subsectors historically plagued by adverse selection and moral hazard are used to identify potential leverage points and intervention strategies for stakeholders to help improve shea quality and returns to primary producers. The analysis suggests the Malian government has the potential to play an important role in this process as a coordinating body and channel captain, with donors and private enterprises playing complementary roles.Information asymmetry, karité, Mali, rural development, shea, women’s income, Agribusiness, Institutional and Behavioral Economics, International Development, Marketing, Q13, Q23, L15, L24, 013, O17,
Tree Tenure in Agroforestry Parklands: Implications for the Management, Utilisation and Ecology of Shea and Locust Bean Trees in Northern Ghana
No full textThe management and utilisation of resources in agroforestry systems are influenced by both land and tree tenure systems, especially where land and tree tenure are distinct, and rights to one do not necessarily lead to rights over the other. Most academic research has examined the impact of land tenure on management and productivity in these landscapes. This thesis investigates the impact of tree tenure alongside other socioeconomic factors through the research question: 'how do local institutional arrangements affect the management, utilisation and ecology of indigenous economic trees in agroforestry parklands?' Shea and locust bean trees, two of the most economically, culturally and ecologically important indigenous agroforestry species in Northern Ghana, are chosen for the case study. This multidisciplinary study utilises several methodologies of data collection and analysis to assess individual and household behaviour in the management of shea and locust bean trees, and the impact on the ecology of these species. The analysis of incentives (and constraints) stemming from differing tenure arrangements reveals differing attitudes among the households to the preservation and planting of these trees on their farmlands. Women, who are primary gatherers of non-timber products from these trees and hence the main beneficiaries, have differing access to these trees, depending both upon the status of their household within the community and the tenure rules in place. Econometric modelling of shea and locust bean tree densities reveals the socioeconomic and institutional determinants of these tree densities on the farmland, highlighting the importance of economic and institutional incentives and constraints in shaping the management practices, and subsequently the ecology of these indigenous economic species. The findings demonstrate that the vagaries of the resource-use dynamics should be taken into consideration by any policy targeted towards promoting sustainable management and utilisation of these valuable parkland species
Cyber Security for Nuclear Power Plants
No full textCyber Security for Nuclear Power Plants by Thomas Shea and Sandro Gaycken and Maurizio Martellini is a meticulous analysis of the current situation regarding the security of Nuclear Power Plants. It describes the current stage, outlining the motivations of potential cyberattacks and how they could be carried out.
It proceeds in presenting an all-comprehensive security circle that provides opportunities for engagement and collaboration to deal with cyberissues at various levels.
Since this paper was presented at the Seoul Nuclear Security Summit of 2012, it ends with useful recommended action for the Summit to take, in order to ensure that the peaceful use of nuclear energy is not vulnerable to cyberattacks

Cancellocochlea Shea & Colgan & Stanisic 2012, n. gen.
No full textCancellocochlea n. gen. Diagnosis. Shell very small, orange brown, biconcave or discoidal/planate with tightly coiled whorls, the last inflated. Protoconch sculpture reticulate (coolongolook) to spiral (heatherae); teleoconch with few sinuate radial ribs; microsculpture cancellate consisting of prominent microradial ribs and low microspiral cords, beaded at their intersection. Aperture narrowly to broadly ovately-lunate. Umbilicus wide U-shaped to wide cup-shaped. Penis tubular with an apical verge that has a lateral pore; longitudinal ridge shaped pilasters present. Epiphallus shorter than penis. Range and habitat. From the Port Stephens area northward to the Manning River drainage basin, NSW; found in rainforest on volcanics, living under logs and rocks. Remarks. Cancellocochlea coolongolook n. sp. and Ca. heatherae n. sp. display significant differences in protoconch sculpture. The protoconch sculpture of Ca. coolongolook has similarities to both Planorbacochlea parriwiensis and P. yessabahensis (both reticulate) while the beaded spiral pattern of Ca. heatherae links it to the Hunter/Port Stephens Planorbacochlea group.Published as part of Shea, M., Colgan, D.

Barringtonica Shea & Colgan & Stanisic 2012, n. gen.
No full textBarringtonica n. gen. Type species. Barringtonica polblue n. sp. –here designated. Etymology. For the Barrington Tops. Diagnosis. Shell very small, silky golden brown weakly planispiral to bi-concave with tightly coiled whorls the last inflated, spire slightly to strongly depressed. Protoconch sculpture spiral consisting of low, flattened, broad spiral cords, with distinct radial growth ripples developing near teleoconch junction; teleoconch with numerous prominent radial ribs; microsculpture cancellate with prominent microradial ribs and low microspiral cords. Aperture broadly ovately-lunate. Umbilicus U shaped to wide, cup-shaped. Penis with an expanded apical portion becoming tubular distally. Verge absent, no pilaster formation observed. Distribution and habitat. Known from the volcanics of the western Barrington Tops rainforest massif off the Scone-Gloucester road and in upper Moonan Brook valley, east of Scone, NSW; found in sub-alpine woodland and vine thicket, living under logs and rocks. Remarks. Barringtonica n. gen. is distinguished by the protoconch sculpture of numerous low flattened spiral cords and radial ridges which become prominent on the latter parts of the protoconch. Comboynea n. gen. has similar low spiral cords that are generally fewer in number, and indistinct underlying radial ridges. Anatomically it differs from both Cumberlandica and Planorbacochlea (most species) chiefly by the lack of a penial verge. The absence of any pilaster formation would seem to indicate that the male reproductive system in the material studied was either immature or seasonally under-developed.Published as part of Shea, M., Colgan, D.
