- Wine tourist profiling in the Porto wine cellars: segmentation based on wine product involvementPublication . Santos, Vasco; Ramos, Paulo; Almeida, Nuno; Marôco, João; Santos-Pavón, EnriqueThis paper segments a sample of 918 Porto wine cellars visitors based on their wine product involvement. A segmentation methodology was applied to the wine product involvement of wine tourists. Three clusters were identified with high, medium and low wine product involvement levels. The relevant theoretical contribution of this study was to provide new evidence of segmentation based on product involvement studies in the wine tourism market field in an area were empirical studies still remain scarce. The findings offer managerial implications regarding the wine tourists’ identification and how to better adapt the visits. This is also the first study demonstrating wine tourist profiling and segmentation specifically applied to involvement with the Porto wine product.
- Database synchronization model for mobile devicesPublication . Domingos, João; Simões, Nuno; Pereira, Paulo; Silva, Catarina; Marcelino, LuisWith the increasing number of mobile devices it is necessary to create adapted solutions for this type of devices that respect their limited processing capacities, memory and bandwidth. We propose a synchronization model based on message digests to synchronize relational databases between mobile devices and a server, in order to minimize the data transferred between the device and the server and to minimize the processing done by the mobile device. The approach consists in a synchronization model where the amount of data to be exchanged has been reduced to the minimum. In order to achieve the model above a registry is done in the device with the new, the modified or removed content, which purpose is to send only the essential data for synchronization from the device to the server. Regarding the synchronization from the server to the device, the modifications are calculated and sent to the device. This model is independent of proprietary solutions and can be adapted to any system or platform, often involving software development to the mobile application and the application server. The results of testing the model show that the proposed model can achieve better synchronization times than the competitor models, while always fulfilling the set objectives.
