A well-formulated research question should incorporate the components of a ‘problem’, an ‘intervention’, a ‘control’, and an ‘outcome’—at least according to the PICO mnemonic. The utility of this format, however, has been said to be limited to clinical studies that pose ‘which’ questions demanding correlational study designs. In contrast, its suitability for descriptive approaches outside of clinical investigations has been doubted. This paper disagrees with the alleged limitations of PICO. Instead, it argues that the scheme can be used universally for every scientific endeavour in any discipline with all study designs. This argument draws from four abstract components common to every research, namely, a research object, a theory/method, a (null) hypothesis, and the goal of knowledge generation. Various examples of how highly heterogenous studies from different disciplines can be grounded in the single scheme of PICO are offered. The finding implies that PICO is indeed a universal technique that can be used for teaching academic writing in any discipline, beyond clinical settings, regardless of a preferred study design.
International exchange programmes have been previously conceptualised based on the ‘opinion leader model’. It expects participants to form positive attitudes towards the host country, and to become influential back home. However, the micro-processes through which this goal can be achieved remain undertheorised. Drawing from Interaction Ritual Theory, this article argues that international exchanges consist of a chain of rituals. They strategically immerse targeted individuals into personal experiences with a shared focus on the host country, transforming the latter into a symbol charged with emotional energy and (strategically devisable) cognitive content. The symbol (now affectively and cognitively laden) is then recurrently invoked to re-circulate through the networks of the participants. A case study of a programme in which the symbol ‘Poland’ became systematically charged with the content of ‘multiculturality’ illustrates this proposition. Practical and theoretical implications (e.g. for the literature on socialisation, norm-diffusion, and face-to-face diplomacy) in international relations are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
