- Early Neolithic settlement and graves in Lisbon’s Historic CentrePublication . Cardoso, João Luís; Martins, FilipeIn recent years, information regarding the human presence during the Early Neolithic period in the Historic Center of Lisbon has increased, as a result of numerous preventive archaeological excavations carried out within the scope of mitigating impacts resulting from the recovery of old buildings or the construction of new ones. Such work, carried out by several Archeology companies that have worked in areas considered to be of greatest archaeological sensitivity within the city of Lisbon, have led to results of exceptional relevance for the knowledge of the first producing societies that occupied this territory from the last quarter of the 6th millennium BC. Thus, not only large settlements were identified, such as Encosta de Sant’Ana and Bairro Alto, integrating several loci, such as Palácio Ludovice. The first structured graves known in Portuguese territory at this time were also identified, in close association with the inhabited spaces, corresponding to individual depositions in the fetal position carried out at the bottom of small graves excavated in the geological substrate. The importance of these discoveries justified the presentation of this synthesis, which summarizes all the information published to date.
- A multi‐objective model for publicly funded festival planningPublication . Almeida, Luís Alçada; Sousa, Nuno; Rodrigues, João CoutinhoThis article proposes a multi-objective mixed-integer linear programming model to assist event managers in obtaining and evaluating non-dominated solutions to the problem of selecting a daily lineup of shows and activities for a festival – be it cultural, sports, ceremonial or any other kind. The model, which is especially adequate for designing festivals with public funding, has five objectives, relating to financial, logistical and how renowned the festival artists or acts are. It includes support for multiple days, multiple stages and differ- ent types of shows, all subject to constraints imposed by the intrinsic nature of the festival itself. The output of the model is a set of optimized daily lineups for the activities that constitute the festival, each correspond- ing to a particular compromise between the five objectives. The approach is demonstrated with a case study for a 5-day festival, for which non-dominated solutions are derived, presented and discussed. Results show that the model can provide a good variety of solutions while ensuring the persistence of the more desirable shows. The model is a novel decision support tool to assist in designing festival lineups that provide optimal audience experience, a key factor in attracting spectators, tourists and increasing comeback value.
