Abstract:
The advent of global navigation satellite systems, and especially GPS, signified a new era in navigation. Although GPS tends to be a panacea in terms of positioning and tracking, there are still cases whereby severe problems can render navigation virtually impossible. Difficult GNSS environments such as forests, heavy canopy covered areas, or urban canyons can have a negative impact on the propagation of satellite signal and introduce large errors in positioning due to signal attenuation. Several techniques have been developed to deal with this issue, e.g. integrated GNSS/INS navigation config

Abstract:
Aid for Trade (AfT), first launched in 2005, has come a long way over the last fifteen years and has undeniably made an important contribution to overcoming the many constraints holding developing countries back from greater participation in international trade, and thus from reaping many of its benefits. This paper first examines which AfT initiatives have sought to enable greater participation by developing countries in digital trade specifically, while also seeking to distil some of the more valuable lessons learned in this process. By way of four case studies, it examines some recent succe

Abstract:
The humanitarian sector is shifting from in-kind aid to digital cash assistance, which promises benefits like efficiency and transparency. However, digital payments need regulation, infrastructure, and user readiness, making them challenging in conflict zones. In Afghanistan and Sudan, pilot projects showed potential but faced obstacles, emphasising adaptability. Digital assets like cryptocurrencies offer solutions but have limitations. Ultimately, aid delivery should be context-specific, prioritising beneficiary needs and flexibility between digital and non-digital methods based on evidence a

BASIC Research focuses on the intersection between social protection and humanitarian approaches in providing assistance in protracted crises. Digital systems can offer benefits in these contexts, but can also increase vulnerabilities. Delivering cash and voucher assistance (CVA) at scale using digital tools in challenging contexts is complex. A lack of digital and financial infrastructure, and the digital exclusion experienced by intended beneficiaries from marginalised communities, are critical issues.

Poliovirus is the causative agent of poliomyelitis, a potentially debilitating disease that is a target for global eradication. Vaccination against poliomyelitis is an important tool in the eradication effort, but one of the available vaccines, the oral poliovirus vaccine, contains live, attenuated strains that can revert to virulent forms. Community transmission of so-called vaccine-derived polioviruses (VDPVs) can contribute to outbreaks, including in areas with no recently reported poliomyelitis cases.
