Transnational reflections on transnational research projects on men, boys and gender relations

This article reflects on the research project, ‘Engaging South African and Finnish youth towards new traditions of non-violence, equality and social well-being’, funded by the Finnish and South African national research councils, in the context of wider debates on research, projects and transnational processes. The project is located within a broader analysis of research projects and projectization (the reduction of research to separate projects), and the increasing tendencies for research to be framed within and as projects, with their own specific temporal and organizational characteristics. This approach is developed further in terms of different understandings of research across borders: international, comparative, multinational and transnational. Special attention is given to differences between research projects that are in the Europe and the EU, and projects that are between the global North and the global South. The theoretical, political and practical challenges of the North-South research project are discussed

Country Concepts and the Rational Actor Trap: Limitations to Strategic Management of International NGOs

Growing criticism of inefficient development aid demanded new planning instruments of donors, including international NGOs (INGOs). A reorientation from isolated project-planning towards holistic country concepts and the increasing rationality of a result-orientated planning process were seen as answer. However, whether these country concepts - newly introduced by major INGOs too - have increased the efficiency of development cooperation is open to question. Firstly, there have been counteracting external factors, like the globalization of the aid business, that demanded structural changes in the composition of INGO portfolios towards growing short-term humanitarian aid; this was hardly compatible with the requirements of medium-term country planning. Secondly, the underlying vision of rationality as a remedy for the major ills of development aid was in itself a fallacy. A major change in the methodology of planning, closely connected with a shift of emphasis in the approach to development cooperation, away from project planning and service delivery, towards supporting the socio-cultural and political environment of the recipient communities, demands a reorientation of aid management: The most urgent change needed is by donors, away from the blinkers of result-orientated planning towards participative organizational cultures of learning.Des critiques croissantes de l'aide au développement inefficace exigent de nouveaux instruments de planification des bailleurs de fonds, y compris les ONG internationales (ONGI). Une réorientation de la planification des projets isolés vers des concepts holistiques de la planification de l’aide par pays ainsi que la rationalité croissante d'un processus de planification orientée vers les résultats ont été considérés comme réponse. Toutefois, si ces concepts de pays - nouvellement introduites par les grandes OING eux aussi - ont augmenté l'efficacité de la coopération au développement est ouvert à la question. Tout d'abord, il y a eu l’impact des facteurs externes, comme la mondialisation de l'entreprise de l'aide, qui a exigé des changements structurels dans la composition des portefeuilles des OING vers la croissance de l'aide humanitaire à court terme. Cela était difficilement compatible avec les exigences de l'aménagement du territoire à moyen terme. Deuxièmement, la vision sous-jacente de la rationalité accrue de la planification, concentré sur les resultats, comme un remède pour les grands maux de l'aide au développement était en soi une erreur. Un changement majeur dans la méthodologie de la planification, étroitement liée à un changement d'orientation dans l'approche de la coopération au développement, qui n’est pas concentrer sur planification du projet et la prestation de services, mais qui soutienne l'environnement socio-culturel et politique des communautés bénéficiaires, exige une réorientation de la gestion de l’aide: Le changement le plus urgent est un changement par les donateurs eux-mêmes, qui devrait implanter des cultures de collaboration étroit avec les partenaires et la population locale

Crucial role of conserved lysine 277 in the fidelity of tRNA aminoacylation by Escherichia coli valyl-tRNA synthetase.

International audienceValyl-tRNA synthetase (ValRS) from Escherichia coli undergoes covalent valylation by a donor valyl adenylate synthesized by the enzyme itself. ValRS could also be modified, although to a lesser extent, by the noncognate isosteric substrate L-threonine from a donor threonyl adenylate synthesized by the synthetase itself, or by the nonsubstrate methionine from methionyl adenylate produced by catalytic amounts of methionyl-tRNA synthetase. MALDI mass spectrometry analysis designated lysines 154, 162, 170, 533, 554, 593, 894, 930, and 940 of ValRS as the target residues for the attachment of valine. Following autothreonylation, lysines 162, 170, 178, 277, 291, 554, 580, 593, 861, 894, and 930 were found to be modified. Finally, L-Met-labeled residues were lysines 118, 162, 170, 178, 277, and 938. Alignment of the available ValRS amino acid sequences showed that lysines 277 and 554 are strictly conserved (with the exception concerning replacement of Lys-277 with a methionine or a tyrosine in archaebacteria), suggesting that these residues might be functionally significant. Indeed, lysine 554 of ValRS is the first lysine of the Lys-Met-Ser-Lys-Ser signature of the catalytic site of class I aminoacyl-tRNA synthetases. Lys-277 which is labeled by L-threonine or L-methionine, and not by L-valine, is located at or near the editing site, in the three-dimensional structure of ValRS. The role of lysine 277 was evaluated by site-directed mutagenesis. The Lys277Ala mutant (K277A) exhibited a posttransfer Thr-tRNA(Val) editing rate that was significantly lower than that observed for the wild-type enzyme. In addition, the K277A substitution altered amino acid discrimination in the editing site, resulting in hydrolysis of the correctly charged cognate Val-tRNA(Val). Finally, significant amounts of mischarged Thr-tRNA(Val) were produced by the K277A mutant, and not by wild-type ValRS. Altogether, our results designate Lys-277 as a likely candidate for nucleophilic attack of misacylated tRNA in the editing site of ValRS

Saharan dust impacts on air quality: What are the potential health risks in West Africa?

Despite the proximity of the Sahara, very few studies about dust impact on air quality and human health have been conducted in West Africa. The lack of data is a major constraint on our understanding of the impacts on human health in this area. We analyzed PM10 concentrations and horizontal visibility recorded in four West African stations. The pollution levels often exceed the standards defined by many countries/regulatory authorities and have been associated with serious health risks outside Africa. Over the Sahelian stations, 45.6% of the days between November 2006 and March 2007 were likely to impact human health and the studied Sudanian population was exposed to potential health effects every 5 days
