Capture of Leptophilic Dark Matter in Neutron Stars

Dark matter particles will be captured in neutron stars if they undergo scattering interactions with nucleons or leptons. These collisions transfer the dark matter kinetic energy to the star, resulting in appreciable heating that is potentially observable by forthcoming infrared telescopes. While previous work considered scattering only on nucleons, neutron stars contain small abundances of other particle species, including electrons and muons. We perform a detailed analysis of the neutron star kinetic heating constraints on leptophilic dark matter. We also estimate the size of loop induced couplings to quarks, arising from the exchange of photons and Z bosons. Despite having relatively small lepton abundances, we find that an observation of an old, cold, neutron star would provide very strong limits on dark matter interactions with leptons, with the greatest reach arising from scattering off muons. The projected sensitivity is orders of magnitude more powerful than current dark matter-electron scattering bounds from terrestrial direct detection experiments.Comment: 26 pages, 8 figures, 3 tables, 2 appendices.

Value and effectiveness of National Immunization Technical Advisory Groups in low- and middle-income countries : A qualitative study of global and national perspectives

© The Author(s) 2019. Published by Oxford University Press in association with The London School of Hygiene and Tropical Medicine.The Global Vaccine Action Plan proposes that every country establish or have access to a National Immunization Technical Advisory Group (NITAG) by 2020. The NITAG role is to produce evidence-informed recommendations that incorporate local context, to guide national immunization policies and practice. This study aimed to explore the value and effectiveness of NITAGs in low- and middle-income countries (LMICs), identifying areas in which NITAGs may require further support to improve their functionality and potential barriers to global investment. A multi-methods study design was used, comprising 134 semi-structured interviews and 82 literature review sources that included 38 countries. Interviews were conducted with 53 global/regional and 81 country-level participants able to provide insight into NITAG effectiveness, including NITAG members, national immunization programme staff, and global agency representatives (e.g. the World Health Organisation, the Bill and Melinda Gates Foundation, Gavi the Vaccine Alliance). The review, including published and unpublished sources on NITAGs in LMICs, was conducted to supplement and corroborate interview findings. Data were analysed thematically. NITAGs were described as valuable in promoting evidence-informed vaccination decision-making, with NITAG involvement enhancing national immunization programme strength and sustainability. Challenges to NITAG effectiveness included: (1) unreliable funding; (2) insufficient diversity of member expertise; (3) inadequate conflicts of interest management procedures; (4) insufficient capacity to access and use evidence; (5) lack of transparency; and (6) limited integration with national decision-making processes that reduced the recognition and incorporation of NITAG recommendations. LMIC NITAGs have developed significantly in the past decade. Well-functioning NITAGs were trusted national resources that enhanced country ownership of immunization provision. However, many LMIC NITAGs require additional technical and funding support to strengthen quality and effectiveness, while maintaining impartiality and ensuring sufficient integration with national decision-making processes. Barriers to sustainable global support need to be addressed for LMIC NITAGs to both continue and develop further.Peer reviewedFinal Published versio

Religious Silence: British Quakerism and British Buddhism Compared

In this paper we explore the communicative function of silence among British Quakers and British Theraviida Buddhists. Both examples link silence to stillness with the implication that non-activity is a means of evoking sacred presence. It is proposed that such an evocation is achieved through attaching aesthetic and ethical value to the performance of stillness and silence. Furthermore, we suggest that the identity of each of these religious communities is, in many respects, defined through the emphasis that is placed on the existential and moral significance of silence

At the London School of Hygiene and Tropical Medicine, we are conducting a study to explore vaccination uptake and health service access amongst Polish and Romanian communities in England. In this summary, we provide the rationale for conducting this research and an overview of the study design

Menstrual hygiene management in disasters: the concerns, needs, and preferences of women and girls in Vanuatu

In disaster settings, women and girls face additional challenges in safely managing menstruation with confidence and dignity. Assessing women’s and girls’ needs and preferences at country level prior to a disaster assists Red Cross National Societies with preparedness planning and development of local menstrual hygiene management (MHM) kits for pre-positioning. This study, conducted in Vanuatu, examined the experiences, concerns, needs, and preferences of women and girls in managing menstruation in disasters. Participants trialled one of four different sanitary products included in a MHM kit. Absorbency, security of fit, and odour were the main determinants of product acceptability. Water supply and safe disposal options influenced the preference for either reusable or disposable products. Access to sanitary products, distribution processes, water supply, and privacy were key concerns. Detailed recommendations within this paper will support the Vanuatu Red Cross in decision making and programming for MHM in disaster preparedness and response

The role of National Immunisation Technical Advisory Groups (NITAGs) in strengthening national vaccine decision-making: A comparative case study of Armenia, Ghana, Indonesia, Nigeria, Senegal and Uganda.

INTRODUCTION: Improving evidence informed decision-making in immunisation is a global health priority and many low and middle-income countries have established National Immunisation Technical Advisory Groups (NITAGs) as independent technical advisory bodies for this purpose. NITAG development and strengthening has received financial and technical support over the past decade, but relatively little evaluation. This study examined NITAGs in six low and middle-income countries (i.e. Armenia, Ghana, Indonesia, Nigeria, Senegal, Uganda), to examine functionality, quality of recommendation development, and integration with national decision-making bodies and processes. METHODS: A mixed-method case-series design, used semi-structured interviews, NITAG meeting observations, and document review. Data were analysed thematically. RESULTS: Five NITAGs had been legally established with terms of reference and appeared well functioning, with Ghana's in development. All NITAGs had standard operating procedures and nomination procedures to ensure a range of expertise, generally comprising 10-15 core, 1-5 secretariat, and several ex-officio members. Aside from economics, NITAGs reported a wide range of member expertise. Newer NITAGs had particular concerns about funding. Four used formal conflict of interest procedures, although some commented that implications were not always understood. NITAGs valued local data, and limited evidence suggested NITAG presence might reinforce data production through surveillance and local research studies. All observed meetings demonstrated due process and evidence-based decision-making processes were generally followed, with a critical role played by working-group data syntheses and assessments. NITAGs were seen as well integrated with ministry of health (MoH) decision-making and MoH interviewees were positive about NITAG contributions, indicating NITAGs had an important role. Collaboration with other bodies was more limited, but mitigated by NITAG members' cross-membership in other bodies. CONCLUSIONS: NITAGs have an important and valued role within national immunisation decision-making. However, their position remains insecure, with the need for sustainable technical and financial support
