- Cultural heritage visits supported on visitors' preferences and mobile devicesPublication . Cardoso, Pedro; Rodrigues, Joao; Pereira, Joao; Nogin, Sergey; Lessa, Joana; Ramos, Celia; Bajireanu, Roman; Gomes, Miguel; Bica, PauloMonuments, museums and cities are great places to feel and experience neat and interesting things. But cultural heritage is experienced differently by different visitors. The more erudite may know beforehand what they intend to explore, while the least literate usually know and are capable of expressing some of their preferences but do not exactly realize what to see and explore. This paper proposes the use of a mobile application to set an itinerary where you can move at your own pace and, at the same time, have all the complementary information you need about each of the points of interest. The application is designed in face of an adaptive user interface where the routing and augmented reality are connected to acknowledge the needs of different user categories, such as elders, kids, experts or general users
- Exploring the meaning of social innovation: a categorisation scheme based on the level of policy intervention, profit orientation and geographical scalePublication . Baptista, Nuno; Pereira, Joao; Moreira, Antonio Carrizo; Matos, NelsonThere has been a growing interest in academia regarding the term 'social innovation', including in disciplines such as sociology, administration, history, management, psychology, and economics. The literature highlights the lack of scientific clarity in the use of the term, and some scholars argue that the term is no more than a 'buzzword' or a 'fad'. This article focusses on the analysis of the conceptualizations of social innovation, contrasting sociological and economical approaches, and adopts an integrative approach to propose a categorization scheme of social innovation projects based on three distinct variables, namely the level of policy support, the profit orientation and the geographical scale. We argue that government support and the scalability of social innovations should be carefully pondered depending on the characteristics of the social innovation initiatives. We conclude that policy support should privilege social innovation initiatives that, while having the potential to deliver social good, are constrained by market failures. In addition, we also argue in favour of policy support for small bottom-up initiatives that have a profit-logic but are not sufficiently robust to survive on their own due to the liabilities of smallness and newness. Finally, we advise caution in public policies supporting scale-up strategies and highlighted the inherent challenges.
- Integrated monitoring of mola mola behaviour in space and timePublication . Sousa, Lara L.; Lopez-Castejon, Francisco; Gilabert, Javier; Relvas, Paulo; Couto, Ana; Queiroz, Nuno; Caldas, Renato; Dias, Paulo Sousa; Dias, Hugo; Faria, Margarida; Ferreira, Filipe; Ferreira, Antonio Sergio; Fortuna, Joao; Gomes, Ricardo Joel; Loureiro, Bruno; Martins, Ricardo; Madureira, Luis; Neiva, Jorge; Oliveira, Marina; Pereira, Joao; Pinto, Jose; Py, Frederic; Queiros, Hugo; Silva, Daniel; Sujit, P. B.; Zolich, Artur; Johansen, Tor Arne; de Sousa, Joao Borges; Rajan, KannaOver the last decade, ocean sunfish movements have been monitored worldwide using various satellite tracking methods. This study reports the near-real time monitoring of finescale (< 10 m) behaviour of sunfish. The study was conducted in southern Portugal in May 2014 and involved satellite tags and underwater and surface robotic vehicles to measure both the movements and the contextual environment of the fish. A total of four individuals were tracked using custom-made GPS satellite tags providing geolocation estimates of fine-scale resolution. These accurate positions further informed sunfish areas of restricted search (ARS), which were directly correlated to steep thermal frontal zones. Simultaneously, and for two different occasions, an Autonomous Underwater Vehicle (AUV) videorecorded the path of the tracked fish and detected buoyant particles in the water column. Importantly, the densities of these particles were also directly correlated to steep thermal gradients. Thus, both sunfish foraging behaviour (ARS) and possibly prey densities, were found to be influenced by analogous environmental conditions. In addition, the dynamic structure of the water transited by the tracked individuals was described by a Lagrangian modelling approach. The model informed the distribution of zooplankton in the region, both horizontally and in the water column, and the resultant simulated densities positively correlated with sunfish ARS behaviour estimator (r(s) = 0.184, p < 0.001). The model also revealed that tracked fish opportunistically displace with respect to subsurface current flow. Thus, we show how physical forcing and current structure provide a rationale for a predator's finescale behaviour observed over a two weeks in May 2014.
- Research and management priorities for Atlantic marine recreational fisheries in Southern EuropePublication . Pita, Pablo; Artetxe, Inaqui; Diogo, Hugo; Gomes, Pedro; Gordoa, Ana; Hyder, Kieran; Pereira, Joao; Pita, Cristina; Rangel, Mafalda; Garcia-Rodrigues, Joao; Sague, Oscar; Veiga, Pedro; Vingada, Jose; Villasante, SebastianMarine Recreational Fishing (MRF) is an important activity in Europe, with 9 million fishers and generating annually 6 billion in direct expenditures. However, there is a lack of data and understanding of MRF in Europe, particularly in Southern countries, which prevents a number of fish stocks from being effectively assessed and managed. In November 2016, a participatory workshop on MRF was held in Vigo (Spain) to identify challenges and opportunities for data collection, and to diagnose key research gaps and management issues for MRF in the Southern European Atlantic. Experts from a wide range of disciplines (researchers, policy makers, fisheries managers and commercial and recreational fishers) highlighted that the management of MRF is a challenge due to complex and dispersed legal frameworks, with multiple administrations involved, and overlapping uses of space with commercial fishing, aquaculture, navigation and tourism, among others. The lack of strong and representative fishing associations hampers research and management initiatives. Effective communication between recreational fishers, researchers and fisheries managers is also lacking. Despite the ecological, social and economic relevance of MRF, there is no systematic and comprehensive collection of information on fishing effort, recreational catches, expenses, social profile and access conditions of European recreational fishers. These data would be useful to avoid biases in the assessment of recreational fisheries due to the great diversity of ecosystems, species and typologies of users. Strategic recommendations and research priorities were also identified to address knowledge gaps and are discussed in the context of the management of MRF across Europe.
