Elections mean little when people trust armed groups more than peacekeepers or the state

Elections may be imminent in the Central African Republic, but the prospective polls are failing to inspire any hope in refugees who fled to neighbouring Cameroon, discovers Veronique Barbelet

Grain Analysis of Pliocene-Pleistocene Sediments from the Chatham Rise

Southern Ocean, sea ice, and ice sheet interactions play an important role in the formation and export of deep water into the adjacent ocean basins. This process of deep ocean circulation has an important consequence on Earth’s meridional distribution and transport of heat, salts, and gases. Ocean Drilling Program (ODP) Site 1123 sits in the path of the southwest Pacific Deep Western Boundary Current (DWBC), where the largest inflow of deep Southern Ocean water enters into any of the ocean basins. Here we present a multi-proxy mid-Pliocene to early Pleistocene (3.5-2.5 Ma) study examining how changes in the inflow of deepwater coincided with Late Pliocene Southern Ocean cooling at 3.3 Ma. Our benthic δ18O record is consistent with the globally integrated stack, LR04. Our benthic δ13C data covaries with X-ray diffraction (XRD) redox proxies (e.g., Mn/Fe and Mn/Al), indicating changes in deep ocean ventilation over glacial-interglacial cycles. Initial grain size data examining the size sorting of silt (sortable silt) implies a potential increase in deep water inflow into the Pacific after 3.3 Ma, as a consequence of sea ice development around the Antarctic margin that is characterized by relatively low δ13C composition, reflecting the enhanced contribution of Circumpolar Deep Water (CDW) with a relatively strong southern sourced signature. Future research will focus on the development of a complement 3.5 to 2.5 Ma grain size record in order to examine the relationship between changes in sediment supply, size sorting of sediment and deep ocean ventilation changes.https://orb.binghamton.edu/research_days_posters_2022/1138/thumbnail.jp

Inclusion and exclusion in humanitarian action: findings from a three-year study

In recent years, the humanitarian sector has started paying more attention to those it leaves behind, such as people with disabilities, older people and speakers of minority languages. Since their needs are so often sidelined amid efforts to serve as many people as quickly as possible, this development is both welcome and overdue. In practice, however, translating attention to inclusion into action remains an uphill struggle. This report seeks to explain why, and to suggest what to do about it. It draws on findings from a three-year research project by the Humanitarian Policy Group (HPG) focused on understanding the dynamics of inclusion and exclusion in humanitarian action, including case studies in north-east Nigeria; the Rohingya refugee response in Cox’s Bazar, Bangladesh; the urban refugee response in Jordan; and the complex mix of post-conflict recovery and natural-hazard-related disasters in Mindanao, the Philippines

Inclusion and exclusion in the north-east Nigeria crisis

The humanitarian response in north-east Nigeria is an important opportunity to examine barriers to more inclusive humanitarian action in large-scale, complex and protracted displacement crises. Acknowledging the immense operational challenges facing humanitarian actors, this study found that the response is not systematically inclusive, which has led to the exclusion of entire communities, therefore undermining its relevance, effectiveness and impartiality

Towards more inclusive, effective and impartial humanitarian action

Failing to include people who are marginalised and discriminated against is not a failure of inclusion but a failure of humanitarian action. Humanitarian actors’ commitment to impartiality requires a focus on prioritising the most urgent cases and non-discrimination. Evidence shows that humanitarian responses often fail to effectively assist and protect those most urgent cases. They can also further exacerbate existing marginalisation and discrimination. Based on a three-year study on inclusion and exclusion in humanitarian action, this policy brief outlines the changes and steps necessary to move towards more inclusive, impartial and effective humanitarian responses. It calls for recentring humanitarian action on effectiveness, relevance and impartiality by adopting a strategic vision for tracking exclusion and supporting more inclusive humanitarian action

Benefits of High Performance Computing applied to the numerical simulation of forged parts

International audienceThe use of numerical simulation in the forging and more generally in the forming industry has been continuously growing and spreading over the past fifteen years. From pure R&D tools in the 1980s and 1990s, these software packages are now used at the designer's level on a daily basis in an industrial and highly competitive environment. This has been achieved through ongoing software development in order to fully benefit from continuously faster computer hardware. Since the end of the 1990s the software package FORGE from Mines ParisTech CEMEF has been designed to support parallel processing. The benefits of this technology using today's multi-core systems are numerous, including drastically reducing computation times, simulating new challenging forming processes, using automatic optimization methods and investigating micro-structural aspects
