Oxfam GB: Accountability Starter Pack
This guide is for those staff who would like to learn more about how to implement activities that are accountable to people and communities. It is primarily aimed at country-level staff responsible for implementing development or humanitarian projects and programmes. The pack begins with an introduction to Oxfam GB's approach to accountability. This is followed by Oxfam International's Accountability Matrix. The Matrix shows the commitments to accountability found within Oxfam International's Programme Standards, and the different levels programmes can achieve in each area. Following this is an explanation of Oxfam GB's Minimum Standards on Accountability.The rest of the pack is divided into four sections - one for each of the four Standards that Oxfam GB is focussing on. For each Standard, there is a brief explanation as to why this Standard is important, then some 'How-To' Guidelines and a Good Practice example from one of Oxfam's programmes. We have also added an extra section on how to improve greater financial transparency as we have had so many requests for guidance specifically on this
The experimental degradation of archaeological human bone by anaerobic bacteria and the implications for recovery of ancient DNA
DNA recovery from human bone has been key to the developing science and
technology of ancient DNA studies. The recovery of macromolecules from bone
however, does not correlate well with recognisable parameters of preservation and
predicting DNA recovery rates from ancient bone can be very difficult. The extent of
degradation of buried bones often depends on environmental taphonomy and can vary
from virtually none to complete and rapid destruction. Although soil or related
microbes are undoubtedly responsible for the majority of this structural degradation
over time, exceptionally little is known of the mechanisms or specific bacteria
involved. Fungi were previously thought to be responsible for destructive processes
(tunnelling) within bone but over the last 30 years the role of bacteria has been
increasingly recognised. Our aim was to develop a less complex in vitro model of the
destructive effects of microbes on bone which might allow a better understanding of
the recovery of mitochondrial or pathogen DNA over time
Lifting the veil of kindness: 'friendship' and settler colonialism in Argentina's Welsh Patagonia
The peaceable impulse of the Welsh in a global context of colonial brutality stands out as a beacon of generosity, yet even this 'friendship' served to reinforce, not undermine, the colonising project in Argentina and beyond, writes Lucy Taylor (Aberystwyth University)
Lead Contamination: Environmental Geochemistry of Gold Mining Villages in Northwest Nigeria
In summer of 2012, dust and processed ore were collected from ~54 villages by U.S. CDC and Nigerian colleagues after the discovery of widespread lead poisoning in northwest Nigeria, and provided to the Environmental Research Laboratory at GSU. Various geochemical analyses were conducted to assess the magnitude of Pb exposure. ICP-AES determined Pb concentrations as high as 61,000 ppm. SEM-EDS and XRD analyses of high concentration samples (\u3e400 ppm) revealed the presence of gold, galena, and cerussite. XRD Cluster Analysis revealed one outlier and 3 clusters. Samples with Pb\u3e400ppm Pb had a strong correlation between Pb and S. GIS Kriging maps illustrate geochemical spatial distribution. Carbonate combustion analysis found TIC has a negative correlation to Pb. Approximately 3% of samples contained \u3e400ppm of Pb (U.S. EPA RSSL). Discovery of galena (PbS) and it’s secondary weathering product cerussite (PbCO3), a highly bioavailable Pb-bearing phase, were discovered in these high Pb samples, indicating a continuing threat to human health
The formation of helium lines in the spectrum of COM J1740-5340
The He I 5876A absorption line recently discovered in the spectrum of the
companion to the millisecond pulsar PSR J1740-5340 is tentatively attributed to
electron impact excitations due to the irradiation of its atmosphere by
gamma-rays emitted by the pulsar's magnetosphere. Numerical calculations,
similar to those carried out previously for Type Ib SNe, indicate that a pulsar
beam with photon energies ~ 1 MeV gives rise to a 5876A line of the observed
strength if the beam's spin-down conversion efficiency approaches 1%. However,
a significant difficulty for the proposed mechanism is the strength of the
singlet line at 6678A. Compared to the corresponding triplets, singlet lines
are weak because of the loss of excitation when photons emitted in decays to
the ground state ionize hydrogen atoms, an effect absent in the hydrogen-free
atmospheres of Type Ib SNe.Comment: Accepted for publication in A&
