Development Aid to Water Management in Mali: The Actors, ‘Global’ Paradigms, and ‘Local’ Translations

Development aid involves a complex network of numerous and extremely heterogeneous actors. Nevertheless, all actors seem to speak the same ‘development jargon’ and to display a congruence that extends from the donor over the professional consultant to the village chief. And although the ideas about what counts as ‘good’ and ‘bad’ aid have constantly changed over time —with new paradigms and policies sprouting every few years— the apparent congruence between actors more or less remains unchanged. How can this be explained? Is it a strategy of all actors to get into the pocket of the donor, or are the social dynamics in development aid more complex? When a new development paradigm appears, where does it come from and how does it gain support? Is this support really homogeneous? To answer the questions, a multi-sited ethnography was conducted in the sector of water-related development aid, with a focus on 3 paradigms that are currently hegemonic in this sector: Integrated Water Resources Management, Capacity Building, and Adaptation to Climate Change. The sites of inquiry were: the headquarters of a multilateral organization, the headquarters of a development NGO, and the Inner Niger Delta in Mali. The research shows that paradigm shifts do not happen overnight but that new paradigms have long lines of descent. Moreover, they require a lot of work from actors in order to become hegemonic; the actors need to create a tight network of support. Each actor, however, interprets the paradigms in a slightly different way, depending on the position in the network. They implant their own interests in their interpretation of the paradigm (the actors ‘translate’ their interests), regardless of whether they constitute the donor, a mediator, or the aid recipient. These translations are necessary to cement and reproduce the network.

Demography in eusocial Hymenoptera

In my doctoral thesis I investigated the evolution of demographic traits within eusocial Hymenoptera. In the social bees, wasps and ants, eusociality has a unique effect on life span evolution as female larvae with the same genetic background can develop through phenotypic plasticity to a queen or a worker with vastly diverging life-history traits. Ant queens belong to the longest-lived insect species, while workers in most species live only a fraction of the queen’s life span. The average colony size of a species is positively correlated with social complexity, division of labor and diverging morphological female phenotypes all of which also affect life span. Therefore the demographic traits of interest in this thesis were life span and colony size. To understand the evolution of worker life span I applied a trade-off model that includes both hierarchical levels important in eusocial systems, namely the colony- and the individual-level. I showed that the evolution of worker life span may be an adaptive trait on the colony level to optimize resource allocation and therefore fitness in response to different levels of extrinsic mortality. A shorter worker life span as a result of reduced resource investments under high levels of extrinsic mortality increases colony fitness. In a further study I showed that Lasius niger colonies produce different aging phenotypes throughout colony development. Smaller colonies which apply a different foraging strategy than larger colonies produced smaller workers, which in turn have a longer life span as compared to larger workers produced in larger colonies. With the switch to cooperative foraging in growing colonies individual workers become less important for the colony caused by their increasing redundancy. Alternatively a trade of between growth and life span may lead to the results found in this study. A further comparative analysis to study the effect of colony size on life span showed a correlation between queen and worker life span when colony size is taken into account. While neither worker nor queen life span was associated with colony size, the differences between queen and worker life span increase with larger average colony sizes across all eusocial Hymenoptera. As colony size affects both queen and worker life span, I aimed to understand which factors lead to the small colony sizes displayed by some ant species. I therefore analyzed per-capita productivity at different colony sizes of eight cavity dwelling ant species. Most colonies of the study species grew larger than optimal productivity predicted. Larger colony size was shown to increase colony homeostasis, the predictability of future productivity and in turn the survival probability of the colony. I also showed that species that deploy an individual foraging mode may circumvent the density dependent decline in foraging success by splitting the colony to several nest sites.

Woher kommen die Infixe im Isu (Kameruner Grasland)?

Die westliche Ring-Sprache Isu (Süd-Bantoid) des Kameruner Graslands setzt ein palatales Infix zum Ausdruck einer Reihe verwandter verbaler Funktionen – imperfektiver Aspekt, Pluraktional, Kausativ – ein. Damit hebt sie sich deutlich vom engeren Bantu- und weiteren Benue-Kongo-Habitus ab, der sich dadurch auszeichnet, Kategorien dieser Art entweder durch verbale Suffixe oder durch Periphrase mithilfe von Hilfsverben zu kodieren. Morphologische Distributionsanalyse, interne Rekonstruktion und externer Vergleich innerhalb der Ring-Gruppe ermöglichen es, die historischen Ursprünge dieses palatalen Infixes einzukreisen und es als Abbauprodukt einer Hochvokal-Reduplikation (ursprünglich in Progressivfunktion) zu identifizieren, wie sie (a) in anderen Niger-Kongo-Sprachen nicht unüblich ist, und (b) wie sie sogar als kognate Vorläuferkonstruktion in der Süd-Ring-Sprache Babungo nachgewiesen werden kann. Funktional-diachron gesehen, wurde im Isu ein vormaliger Progressiv in zunehmendem Maße als Imperfektiv grammatikalisiert und ist damit in die Domäne der älteren Imperfektiv-Strategie -ə (< *-a) eingedrungen. Auf diese Art fügen sich das Isu und seine nächsten Verwandten trotz dieser eigentümlichen Infix-Phänomene sauber in das Gesamtbild westafrikanischer Sprachen ein.

On genitive linking in Songhay

Die Songhaysprachen verwenden unterschiedliche Konstruktionen, um Genitivbeziehungen auszudrücken. In den hier 'Mainstream' genannten Songhaysprachen findet sich vornehmlich eine Konstruktion ohne weitere Verbindungselemente mit dem Possessor an erster Stellung. In den so genannten nördlichen Songhaysprachen findet sich die gleiche Reihenfolge von Possessor und Possessum, dort werden sie jedoch durch eine Adposition n getrennt. Die Forschung hat bisher meistens die Ansicht vertreten, dieses n sei aus dem Tuareg entlehnt worden, wo man ja eine Genitivpräposition n hat. Diese Ableitung ist jedoch problematisch, da im Tuareg der Possessor dem Possessum folgt, also eine umgekehrte Reihenfolge wie im Songhay vorliegt. In diesem Artikel werde ich versuchen, für eine songhay-interne Ableitung von n zu argumentieren. Zwei verschiedene Lösungen werden vorgeschlagen. Der erste An¬satz geht davon aus, dass es sich um das Relikt einer alten Genitivpartikel, ánè, handelt, die sich noch im Pronomen wane 'der von' finden lässt. Im zweiten Ansatz wird angenommen, dass n ursprünglich die Trennung von zwei NPs markierte. Im Mainstream Songhay hätte sich dieses Element zum Transitivmarkierer im Perfektiv entwickelt, im nördlichen Songhay dagegen zum Markierer von Genetivkonstruktionen haben.

'Balance of Terror' -- Rival Militias and Vigilantes in Nigeria

Militias and vigilantes that assume public authority by fighting crime reject the laws of the state, yet they have no other set of rules to regulate their activities. Many of them claim to be accountable to their ethnic or religious community on whose behalf they operate. But their communities have found no means to institutionalise control over them. Moreover, there are no institutions to settle conflicts between different militias and vigilantes. On a local level, rival groups have reached informal arrangements. However, these compromises are unstable, as they reflect fragile alliances and shifting balances of power. Leaders of militias and other 'self-determination groups' have suggested organising a conference of all ethnic nationalities in Nigeria in order to design a new constitution that would give militias and vigilantes a legal role and define their authority. But the groups compared in this article – Oodua People's Congress, Sharia Vigilantes, Bakassi Boys, MASSOB, and Niger Delta militias – pursue very divergent interests, and they are far from reaching a consensus on how to contain violence between them.

Geochemical and isotopic characterization of the Bodélé Depression dust source and implications for transatlantic dust transport to the Amazon Basin

The Bodélé Depression (Chad) in the central Sahara/Sahel region of Northern Africa is the most important source of mineral dust to the atmosphere globally. The Bodélé Depression is purportedly the largest source of Saharan dust reaching the Amazon Basin by transatlantic transport. Here, we have undertaken a comprehensive study of surface sediments from the Bodélé Depression and dust deposits (Chad, Niger) in order to characterize geochemically and isotopically (Sr, Nd and Pb isotopes) this dust source, and evaluate its importance in present and past African dust records. We similarly analyzed sedimentary deposits from the Amazonian lowlands in order to assess postulated accumulation of African mineral dust in the Amazon Basin, as well as its possible impact in fertilizing the Amazon rainforest. Our results identify distinct sources of different ages and provenance in the Bodélé Depression versus the Amazon Basin, effectively ruling out an origin for the Amazonian deposits, such as the Belterra Clay Layer, by long-term deposition of Bodélé Depression material. Similarly, no evidence for contributions from other potential source areas is provided by existing isotope data (Sr, Nd) on Saharan dusts. Instead, the composition of these Amazonian deposits is entirely consistent with derivation from in-situ weathering and erosion of the Precambrian Amazonian craton, with little, if any, Andean contribution. In the Amazon Basin, the mass accumulation rate of eolian dust is only around one-third of the vertical erosion rate in shield areas, suggesting that Saharan dust is “consumed” by tropical weathering, contributing nutrients and stimulating plant growth, but never accumulates as such in the Amazon Basin. The chemical and isotope compositions found in the Bodélé Depression are varied at the local scale, and have contrasting signatures in the “silica-rich” dry lake-bed sediments and in the “calcium-rich” mixed diatomites and surrounding sand material. This unexpected finding implies that the Bodélé Depression material is not “pre-mixed” at the source to provide a homogeneous source of dust. Rather, different isotope signatures can be emitted depending on subtle vagaries of dust-producing events. Our characterization of the Bodélé Depression components indicate that the Bodélé “calcium-rich” component, identified here, is most likely released via eolian processes of sand grain saltation and abrasion and may be significant in the overall global budget of dusts carried out by the Harmattan low-level jet during the winter.

New copper(II) complexes with isoconazole: Synthesis, structures and biological properties

There is an increasing demand for novel metal-based complexes with biologically relevant molecules in technology and medicine. Three new Cu(II) coordination compounds with antifungal agent isoconazole (L), namely mononuclear complexes CuCl2(L)(2) (1), and Cu(O2CMe)(2)(L)(2)center dot 2H(2)O (2) and coordination polymer Cu(pht)(L)(2)(n) (3) (where H(2)pht - o-phthalic acid) were synthesized and characterized by IR spectroscopy, thermogravimetric analysis and X-ray crystallography. X-ray analysis showed that in all complexes, the isoconazole is coordinated to Cu(II) centres by a N atom of the imidazole fragment. In complex I, the square-planar environment of Cu(II) atoms is completed by two N atoms of isoconazole and two chloride ligands, whereas the Cu(II) atoms are coordinated by two N atoms from two isoconazole ligands and two O atoms from the different carboxylate residues: acetate in 2 and phthalate in 3. The formation of an infinite chain through the bridging phthalate ligand is observed in 3. The biosynthetic ability of micromycetes Aspergillus niger CNMN FD 10 in the presence of the prepared complexes 1-3 as well as the antifungal drug isoconazole were studied. Complexes 2 and 3 accelerate the biosynthesis of enzymes (beta-glucosidase, xylanase and endoglucanase) by this fungus. Moreover, a simplified and improved method for the preparation of isoconazole nitrate was developed.
