Plan's CCCD approach - Country study PLAN-Kenya

The field study for Kenya, a part of the strategic formative evaluation on CCCD, was carried out August 16-23, 2009. This country study aimed at studying CCCD as an approach for development and how it was applied by Plan Kenya. The executive summary covers the main findings and recommendations of the field study in Kenya. Detailed findings and recommendations concerning Plan Kenya are described in this report. Findings and recommendations when relevant are incorporated in the synthesis report: Strategic Evaluation Study on CCCD for Plan NLNO. After the introduction the report starts with an overview on the country context and Plan Kenya. The third chapter presents how Plan staff and partners view CCCD, fourth chapter is on how CCCD works in practice, chapter 5 looks in more detail on partnerships. The report ends with a summary of the findings and recommendations. CCCD was introduced in Kenya in 2004. Programmes undertaken by Plan Kenya do take child centredness and community development as their main point of departure

Indirect Dark Matter Searches in the Light of ATIC, FERMI, EGRET and PAMELA

Recently, new data on antiprotons and positrons from PAMELA, e- + e+ spectra from ATIC, FERMI and HESS up to TeV energies all indicate deviations from expectations, which has caused an interesting mix of new explanations, ranging from background, standard astrophysical sources to signals from dark matter (DM) annihilation. Unfortunately, the excess in positrons is not matched with obvious excesses in antiprotons or gamma rays, so a new class of DM scenarios with leptophilic WIMP candidates have been invoked. On the other hand, the increase in the positron fraction, which could have had any spectral shape for new physics, matches well the shape expected from proton background.Comment: Invited talk at SUSY09, the 17th International Conference on Supersymmetry and the Unification of Fundamental Interactions, Boston, 200

Large N Elliptic Genus and AdS/CFT Correspondence

According to one of Maldacena's dualities, type IIB string theory on AdS_3 X S^3 X K3 is equivalent to a certain N=(4,4) superconformal field theory. In this note we compute the elliptic genus of the boundary theory in the supergravity approximation. A finite quantity is obtained once we introduce a particular exclusion principle. In the regime where the supergravity approximation is reliable, we find exact agreement with the elliptic genus of a sigma model with target space K3^N/S_N.Comment: 13 pages, LaTe

First record of a white rough-toothed dolphin (Steno bredanensis) off West Africa including notes on rough-toothed dolphin surface behaviour

In June 2009, a white rough-toothed dolphin (Steno bredanensis) calf was photographed in a group of at least 50 dolphins in the southern Gulf of Guinea, 95 nauticol miles off the Gabon coast (01°45'S 007°29'E), West Africa. Reports of unusually pigmented cetaceans are infrequent and this record represents the first of an all-white rough-toothed dolphin. Furthermore, there is little documentation concerning rough-toothed dolphins and this note contributes to the knowledge of this species in tropical West African water

Perspectives on the detection of supersymmetric Dark Matter

Up to now searches for Dark Matter (DM) detection have not been successful, either because our paradigm in how DM signals should look like are wrong or the detector sensitivity is still too low in spite of the large progress made in recent years. We discuss both possibilities starting with what we know about DM from cosmology and why Supersymmetry provides such an interesting paradigm for cosmology and particle physics in order to appreciate what it means to give up this paradigm. In addition, we compare the predicted cross sections for direct and indirect DM detection with observations with emphasis on the latest developments. Especially, we discuss the possible origins of the two hotly debated candidates for a DM annihilation signal, namely the positron excess and the Fermi GeV excess, which are unfortunately incompatible with each other and more mundane astrophysical explanations exist.Comment: 18 pages, 12 figures.
