- Pedestal modelling is crucial to predict the performance of future fusion devices. Current modelling efforts suffer either from a lack of kinetic physics, or an excess of computational complexity. To ameliorate these problems, we take a first-principles multiscale approach to the pedestal. We will present three separate sets of equations, covering the dynamics of edge localised modes (ELMs), the inter-ELM pedestal and pedestal turbulence, respectively. Precisely how these equations should be coupled to each other is covered in detail. This framework is completely self-consistent; it is derived from first principles by means of an asymptotic expansion of the fundamental Vlasov-Landau-Maxwell system in appropriate small parameters. The derivation exploits the narrowness of the pedestal region, the smallness of the thermal gyroradius and the low plasma beta (the ratio of thermal to magnetic pressures) typical of current pedestal operation to achieve its simplifications. The relationship between this framework and gyrokinetics is analysed, and possibilities to directly match our systems of equations onto multiscale gyrokinetics are explored. A detailed comparison between our model and other models in the literature is performed. Finally, the potential for matching this framework onto an open-field-line region is briefly discussed.

- Guided group activities, where tourists consume with other tourists, are common and important. Although the tourism and services literature suggests customer-employee rapport impacts customer satisfaction, the composition and impact of tourist-tourist rapport in guided group activities have received minimal attention. We use a three-study mixed method approach to conceptualize and examine tourist-tourist rapport in guided group activities. Study 1 identifies two recognized dyadic dimensions of tourist-tourist rapport (enjoyable interaction and personal connection) and two new group-based dimensions (group attentiveness and service congruity). Study 2 (video experiment) and Study 3 (field experiment) find that enjoyable interaction and personal connection mediate the relationship between group attentiveness and service congruity with satisfaction. Thus, touristtourist rapport in a group context is more multidimensional and complex than previously conceptualized for customer-employee rapport and non-group contexts. Further, we find tourist-tourist rapport is a critical service factor such that high levels satisfy, while low levels dissatisfy.
