The facility location problem with capacity transfers
2020
Abstract This paper explores the concept of capacity transfer in the context of capacitated facility location problems. This is accomplished by assuming that facilities with surplus capacity/production can cooperate with those facing shortage by transferring part of that capacity/production. Such a transfer incurs a cost that nonetheless may be compensated by savings both in the installation costs and in the distribution costs. Mixed-integer mathematical programming models are proposed for the problem. A distinction is made between the case in which the triangle inequality holds for the transfer costs and the case in which it does not. We present compact models, which are enhanced with vali…
‘Tool port’ to ‘landlord port’: a game theory approach to analyse gains from governance model transformation
2018
This study investigates potential port users’ surplus and terminal operators’ profits due to transforming port governance from the ‘tool port’ model to the ‘landlord port’ model. Although the landl...
Videogames and Inclusive Education project in Palermo Secondary School
2017
Attempting to support videogames for education and learning purposes has prompted considerable attention over the last years. The great variety of digital games available has provided much for educators and researchers to explore, resulting in intense disputes that many games have benefits both in and out of the classroom for learners of secondary school. Many games have been revealed as strong educational tools for their design as well as their effective implementation in the classroom. Thus far, research on the impact and outcomes of this pedagogy is somewhat limited, but promising. Further projects and evaluations are required to provide the support needed in order to encourage more teac…
Commentary: ethnography, critique and the state. Some thoughts on “fiscal anthropological insights into the heart of contemporary statehood”1
2018
This commentary explores the assets and liabilities of anthropology for the study of core functions of statehood (such as taxation) that increasingly become a matter of transnational negotiation an...
Other-Repetition as a Resource for Participation in the Activity of Playing a Video Game
2009
This article offers an empirically based contribution to the growing body of studies using Conversation Analysis (CA) as a tool for analyzing second/foreign language learning in and through interaction. Building on a sociointeractional view of learning as grounded in the structures of participation in social activities, we apply CA methods to examine the affordances offered by interaction during the activity of playing a video game for additional language learning. We focus on one type of interactional practice, lexical and prosodic repetition, as a recurring resource through which players attend to the game and collaboratively build their understanding and experience of game events. We arg…
Collaborative Game‐play as a Site for Participation and Situated Learning of a Second Language
2009
This paper addresses additional language learning as rooted in participation in the social activity of collaborative game‐play. Building on a social‐interactional view of learning, it analyses some of the detailed practices through which players attend to a video game as the material and semiotic structure that shapes play and creates affordances for additional language learning. We describe how players engage with the language resources offered by the game, drawing on the vocabulary, constructions, prosodic features and utterances modelled on game dialogue, in building their own actions during collaborative play. With these resources, the players display their ongoing engagement with the g…
Fishing pressure impacts the abundance gradient of European lobsters across the borders of a newly established marine protected area
2019
Marine protected areas (MPAs) are considered viable fisheries management tools due to their potential benefits of adult spillover and recruitment subsidy to nearby fisheries. However, before–after control–impact studies that explore the biological and fishery effects of MPAs to surrounding fisheries are scarce. We present results from a fine-scale spatial gradient study conducted before and after the implementation of a 5 km 2 lobster MPA in southern Norway. A significant nonlinear response in lobster abundance, estimated as catch-per-unit-effort (CPUE) from experimental fishing, was detected within 2 years of protection. After 4 years, CPUE values inside the MPA had increased by a magnitu…
Lobster and cod benefit from small-scale northern marine protected areas: inference from an empirical before - after control-impact study
2013
Published version of an article from the journal: Proceedings of the Royal Society B-Biological Sciences. Alsop available from the Royal Society: http://dx.doi.org/10.1098/rspb.2012.2679 Open Access Marine protected areas (MPAs) are increasingly implemented as tools to conserve and manage fisheries and target species. Because there are opportunity costs to conservation, there is a need for science-based assessment of MPAs. Here, we present one of the northernmost documentations of MPA effects to date, demonstrated by a replicated before-after control-impact (BACI) approach. In 2006, MPAs were implemented along the Norwegian Skagerrak coast offering complete protection to shellfish and parti…
Gamma interferon blocks gammaherpesvirus reactivation from latency in a cell type-specific manner
2007
Gammaherpesviruses are important pathogens whose lifelong survival in the host depends critically on their capacity to establish and reactivate from latency, processes regulated by both viral genes and the host immune response. Previous work has demonstrated that gamma interferon (IFN-gamma) is a key regulator of chronic infection with murine gammaherpesvirus 68 (gammaHV68), a virus that establishes latent infection in B lymphocytes, macrophages, and dendritic cells. In mice deficient in IFN-gamma or the IFN-gamma receptor, gammaHV68 gene expression is altered during chronic infection, and peritoneal cells explanted from these mice reactivate more efficiently ex vivo than cells derived from…
