On the analysis of masonry structures without box behavior
Assessment of the seismic performance of structures is still challenge. Historic masonry structures exhibit peculiar properties (low tensile strength and lack of box behavior) that make the task of the analyst even more difficult. It seems that traditional design and assessment methods, similar to the ones currently used for reinforced concrete structures, are not applicable.
This paper provides a review of the seismic analysis of masonry structures without box behavior. Different methods of structural analysis are discussed and a comparison is made between pushover methods and non-linear dynamic analysis with time integration. Three cases studies (S. Torcato church, Qutb Minar and “Gaioleiros” buildings) were used and the results show that traditional, adaptive or modal pushover analyses are not totally in agreement with non-linear dynamic analysis or experimental observations, namely cycle and rigid block behavior (rocking) and the out-of-plane behavior.The present work is partly funded by FCT (Portuguese Foundation for Science and Technology), through project POCI/ECM/61671/2004, "Seismic vulnerability reduction of old masonry buildings" and project PTDC-ECM-68188-2006, "Innovative solutions for non-load bearing masonry infills"

Pokémon GO is serious leisure that increases the touristic engagement, physical activity and sense of happiness of players
© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. This study investigates Pokémon Go as a form of serious leisure including its impact on the touristic engagement, physical activity and sense of happiness of players. This location-aware augmented reality mobile game continues to be played by millions of people every day. Based on an online survey identifying 438 Pokémon GO players from 34 countries the present study examines if playing Pokémon GO sends people to locations, cities and countries beyond their normal sphere of activity and makes them feel happier and more successful. Descriptive statistics, factor analysis and regression were used to analyze data. Results show that playing the networked game on a mobile device increases visitation to local tourism attractions, and motivates people to spend more time outdoors and walking. It also sends them to cities and countries they might not otherwise visit and acts as an alternative to spending time indoors playing computer games. Surveyed players feel happier and more successful after playing the game. Pokémon GO might have value as the center of a tourism product for those players. The opportunity to acquire Pokémon and encounter others involved in the game across a destination, or in a single attraction, could pull players to that place. These are the attributes of people in pursuit of serious leisure
