In southeast Tanzania, ten canvas huts raised on wooden foundations occupy a plot of cleared rice field. Designed to simulate malaria transmission on the domestic scale, the experimental hut is constructed in the fashion of indigenous homes (complete with villagers, paid to spend the night), but is structurally modified to render mosquito behaviours visible. The experiment's domestic camouflage provides the setting for multiple, and reciprocal, hostings: between parasite, mosquito, and human, and between villagers, volunteers, and scientists. This paper explores the valences of hospitality when the 'home' becomes a site of experimentation, and the cosmopolitan encounters these experiments entail.RésuméDans le sud‐est de la Tanzanie, dix cases en toile dressées sur des fondations en bois occupent une parcelle de rizière dégagée. Conçue pour simuler la transmission du paludisme à l'échelle domestique, la case expérimentale est construite à la manière des maisons indigènes (avec même des villageois, payés pour y passer la nuit), mais sa structure est modifiée de façon à rendre le comportement des moustiques visible. Le camouflage domestique de l'expérience crée le cadre de multiples hébergements réciproques : entre le parasite, le moustique et l'homme, entre villageois, bénévoles et scientifiques. Le présent article explore les valences de l'hospitalité quand « la maison » devient un lieu d'expérimentation, ainsi que les rencontres cosmopolites qu'impliquent ces expériences.

What are the epistemological and political contours of evidence today? This introduction to the Special Issue on Global Evidence lays out key shifts in the contemporary politics of knowledge and describes the collective contribution of the five papers as an articulation of what we describe as a 'new empiricism', exploring how earlier historical appeals to evidence to defend political power and decision-making both chime with and differ from those of the contemporary era. We outline some emerging empirical frontiers in the study of instruments of calculation, from the evolution of the randomised controlled trial (RCT) to the growing importance of big data, and explore how these methodological transformations intersect with the alleged crisis of expertise in the 'post-truth' era. In so doing, we suggest that the ambiguity of evidence can be a powerful tool in itself, and we relate this ambiguity to the ideological commitment and moral fervour that is elicited through appeals to, and the performance of, evaluation.

Over the past decades, infectious disease epidemics have come to increasingly pose major global health challenges to humanity. The Anthropology of Epidemics approaches epidemics as total social phenomena: processes and events which encompass and exercise a transformational impact on social life whilst at the same time functioning as catalysts of shifts and ruptures as regards human/non-human relations. Bearing a particular mark on subject areas and questions which have recently come to shape developments in anthropological thinking, the volume brings epidemics to the forefront of anthropological debate, as an exemplary arena for social scientific study and analysis.

Today, malaria prevention hinges upon two domestic interventions: insecticide-treated bed nets and indoor residual spraying. As mosquitoes grow resistant to these tools, however, novel approaches to vector control have become a priority area of malaria research and development. Spatial repellency, a volumetric mode of action that seeks to reduce disease transmission by creating an atmosphere inimical to mosquitoes, represents one way forward. Drawing from research that sought to develop new repellent chemicals in conversation with users from sub-Saharan Africa and the United States, we consider the implications of a non-insecticidal paradigm of vector control for how we understand the political ecology of malaria.

Strong leadership capabilities are essential for effective health services, yet definitions of leadership remain contested. Despite the acknowledged contextual specificity of leadership styles, most leadership theories draw heavily from Western conceptualizations. This cultural bias may attenuate the effectiveness of programmes intended to transform healthcare practice in Sub-Saharan Africa, where few empirical studies on health leadership have been conducted. This paper examines how effective leadership by doctors was perceived by stakeholders in one particular context, Sierra Leone. Drawing together extensive experience of in-country healthcare provision with a series of in-depth interviews with 27 Sierra Leonean doctors, we extended a grounded-theory approach to come to grips with the reach and relevance of contemporary leadership models in capturing the local experiences and relevance of leadership. We found that participants conceptualized leadership according to established leadership models, such as transformational and relational theories. However, participants also pointed to distinctive challenges attendant to healthcare provision in Sierra Leone that required specific leadership capabilities. Context-specific factors included health system breakdown, politicization in the health sector and lack of accountability, placing importance on skills such as persistence, role modelling and taking initiative. Participants also described pressure to behave in ways they deemed antithetical to their personal and professional values and also necessary in order to continue a career in the public sector. The challenge of navigating such ethical dilemmas was a defining feature of leadership in Sierra Leone. Our research demonstrates that while international leadership models were relevant in this context, there is strong emphasis on contingent or situational leadership theories. We further contribute to policy and practice by informing design of leadership development programmes and the establishment of a more ...

Following the 2013–2016 outbreak of Ebola virus disease (EVD) in West Africa, governments across the region imposed a ban on the hunting and consumption of meat from wild animals. This injunction was accompanied by public health messages emphasising the infectious potential of wild meat, or 'bushmeat.' Using a qualitative methodology, we examine the local reception and impact of these interventions. Fieldwork was focused in 9 villages in the Eastern and Southern provinces of Sierra Leone between August and December 2015. We conducted 47 semi-structured interviews, coordinated 12 informal group discussions, and conducted direct observations throughout. We also draw from research undertaken in Sierra Leone immediately before the outbreak, and from our participation in the EVD response in Guinea and Sierra Leone. Our findings underscore the social and political reverberations of hunting proscriptions. Messaging that unilaterally stressed the health risk posed by wild meat contradicted the experiences of target publics, who consume wild meat without incident. This epistemic dissonance radically undercut the effectiveness of the ban, which merely served to proliferate informal networks of wild animal trade and sale—rendering the development of acceptable, evidence-based surveillance and mitigation strategies for zoonotic spillovers almost impossible. Further, the criminalisation of wild meat consumption fuelled fears and rumours within communities under considerable strain from the health, social, and economic effects of the epidemic, entrenching distrust towards outbreak responders and exacerbating pre-existing tensions within villages. These unintended consequences are instructive for public health emergency response and preparedness. While wild meat is a risk for zoonotic infection, mitigating those risks entails interventions that fully take into account the local significances of hunting—including a communicative engagement that is designed, validated, and continually refined before emergency situations. Ultimately, our research questions the value of legal sanctions as a means of behavioural change in an emergency context.
