Private–Public Partnerships as Strategic Alliances
2008
A new approach to the design of concession contracts of port infrastructures that adapts some of the methods used in the design and start-up of strategic alliances is presented. From a cost–benefit analysis of the project, based on the industry benchmarks, a revenue-sharing model dependent on the investment interest and the risk undertaken or transferred by each partner was formulated. This model aids in the calculation of the amount of the canons (lease and royalty charges) that should be stated in the contract. Also, to avoid complicated renegotiations and undesired deadlock situations, methods are presented for the dynamic actualization of such canons according to changes that might occ…

Moving closer? Comparing regional adjustments to shocks in EMU and the United States
2020
Highlights • Interstate migration is the main adjustment channel to labor demand shocks for the US. • EMU countries adjust through changes in labor force participation and unemployment. • Price flexibility is more important as a shock absorber for EMU. • Risk-sharing mechanisms have been more effective in the US than in the EMU. • The strength of these channels has increased for EMU ad declined for the United States.
Video sharing application for educational use: Usability and impacts of participation modes
2014
For the past few years, the use of video lectures in universities has been on the increase. Production of video lectures will bring flexibility that is needed for study and enable the utilization of pedagogical solutions based on new videos. On the other hand, applications for the sharing and use of lecture videos clearly designed for educational requirements are not available. This article introduces an application for the sharing and use of videos. The application was designed and implemented for educational purposes, and it has been in use already for two years. The article examines, with the help of a SUS survey, students' and lecturer's satisfaction with the application and its usabili…
Automatic ontology-based user profile learning from heterogeneous web resources in a big data context
2013
The Web has developed to the biggest source of information and entertainment in the world. By its size, its adaptability and flexibility, it challenged our current paradigms on information sharing in several areas. By offering everybody the opportunity to release own contents in a fast and cheap way, the Web already led to a revolution of the traditional publishing world and just now, it commences to change the perspective on advertisements. With the possibility to adapt the contents displayed on a page dynamically based on the viewer's context, campaigns launched to target rough customer groups will become an element of the past. However, this new ecosystem, that relates advertisements wit…
The forager's dilemma: food sharing and food defense as risk-sensitive foraging options.
2003
Although many variants of the hawk-dove game predict the frequency at which group foraging animals should compete aggressively, none of them can explain why a large number of group foraging animals share food clumps without any overt aggression. One reason for this shortcoming is that hawk-dove games typically consider only a single contest, while most group foraging situations involve opponents that interact repeatedly over discovered food clumps. The present iterated hawk-dove game predicts that in situations that are analogous to a prisoner's dilemma, animals should share the resources without aggression, provided that the number of simultaneously available food clumps is sufficiently la…
Analysis of HLA-DQA, HLA-DQB frequencies in a group of Sardinian centenarians
2006
Human leukocyte antigen (HLA) alleles, regulating type and intensity of the immune response, might influence life expectancy. In previous case-control studies the authors have demonstrated that both HLA-DR and -DQ alleles are not associated with longevity in the Sardinian population. On the other hand, association studies are subjected (as part of the homogeneity of the population in terms of geographic origin) to a number of possible confounding factors. Therefore, the authors typed the HLA-DQA1 and HLA-DQB1 alleles in 24 sibs (age range 85 to 97) of 17 centenarians by PCR-SSP. Sib pair analysis showed non-significant differences between the observed and expected percentage of DQA* or DQB1…
Sustainable Infrastructure Projects: Systemic versus Traditional Delivery Models
2021
Sustainability involves multiple environmental, technical, social and economic factors, and such complex analysis requires systemic solutions. Delivery models are key to achieving system benefits and enhancing sustainable development in infrastructure investments. They define the phases of a project, incentive structures, risk sharing and the relationships among the actors in it. They are usually developed early in the project and determine the project dynamics and outcomes. We compared traditional delivery models with systemic ones. We identified and illustrated elements that differ between them through two cases. The contribution is an increased understanding of how systemic infrastructur…
Indication for social interaction during the Central European Late Upper Palaeolithic: Evidence from the Magdalenian site of Oelknitz, Structure 1 (T…
2012
Abstract The current paper reports on the faunal assemblage from Structure 1 at the German Magdalenian site of Oelknitz. The composition of the fauna is characterised by a dominance of horse. The horses were exploited for meat and marrow. A strict spatial separation of carcass parts is obvious, also observed at other Magdalenian sites, where the evidence was interpreted in terms of social interaction and food sharing. This is discussed against the contextual background of the site of Oelknitz. It is suggested that the way in which Magdalenians interacted socially is independent of site function.
Exploring Public Sector’s Roles in Collaborative Consumption – A Research Agenda
2018
Part 2: Digital Collaboration and Social Media; International audience; Motivated by the growing significance of sharing economy within our society, we here discuss which role the public sector may have within collaborative consumption (CC). CC refers to a business model grounded on peer-to-peer based sharing of goods and services through community-based online services. While public sector to a large extent has transformed from formalised bureaucratic structures into more hybrid organisations, focusing on the co-creation between public and private stakeholders, public sector’s role within the sharing economy is still in need for further investigation. We reflect on the need for studying ho…
