Current research on data in policy has primarily focused on street-level bureaucrats, neglecting the changes in the work of policy advisors. This research fills this gap by presenting an explorative theoretical understanding of the integration of data, local knowledge and professional expertise in the work of policy advisors. The theoretical perspective we develop builds upon Vickers’s (1995, The Art of Judgment: A Study of Policy Making, Centenary Edition, SAGE) judgments in policymaking. Empirically, we present a case study of a Dutch law enforcement network for preventing and reducing organized crime. Based on interviews, observations, and documents collected in a 13-month ethnographic fieldwork period, we study how policy advisors within this network make their judgments. In contrast with the idea of data as a rationalizing force, our study reveals that how data sources are selected and analyzed for judgments is very much shaped by the existing local and expert knowledge of policy advisors. The weight given to data is highly situational: we found that policy advisors welcome data in scoping the policy issue, but for judgments more closely connected to actual policy interventions, data are given limited value.

In spite of renewed attention for practices in tourism studies, the analysis of practices is often isolated from theories of practice. This theoretical paper identifies the main strands of practice theory and their relevance and application to tourism research, and develops a new approach to applying practice theory in the study of tourism participation. We propose a conceptual model of tourism practices based on the work of Collins (2004), which emphasises the role of rituals in generating emotional responses. This integrated approach can focus on individuals interacting in groups, as well as explaining why people join and leave specific practices. Charting the shifting of individuals between practices could help to illuminate the dynamics and complexity of tourism systems.
