The Role of Public Entity in Coopetiotion and Convergence
2007
We investigate upon the strategic impact of the public entity to catalyze coalition formation among competitors around an essential facility. The public entity is usually represented as if moved by mere political scopes. However, the presence of a publicly-owned asset or infrastructure, which can be termed an essential facility, gives leeway to shed the opportunity to satisfy potentially new and different type of demand or consumer cluster needs. The increase in value stemming from a renewal in the utilization of the facility might loosen up political restraints against the involvement in the management of the facility of a multiplicity of actors. This allows us to add a new dimension to th…
Science and technology parks : measuring their contribution to society through social accounting
2020
Science and Technology Parks (STPs) have made a positive contribution to regional development in the last decades. In general, the assessment of their level of performance has been based on two major variables: number of new companies and number of new jobs created. In this paper we propose the use of social accounting to measure the social value (SV) generated by STPs as an additional tool to assess the level of contribution of STPs to social development. Social accounting could be of interest for policy makers and regional governments in order to evaluate regional STPs and their social performance. In addition, in this paper we present an innovative methodology for calculating SV. Instead…
The dynamic interactive pattern of assimilation and contrast: Accounting for standard extremity in comparative evaluations
2021
Abstract Social judgments are often influenced by comparison to some standard in the environment, either moving the judgment closer (assimilating) to or away (contrasting) from this standard. Which direction this effect will take depends heavily on the relative standing of these standards on the judgment dimension compared to the target of the judgment. In previous research, items and comparison standards were often selected arbitrarily, ignoring or simplifying their influence substantially. The current work takes a fine-grained holistic curve fitting approach to measure response patterns across a wide range of standard extremities, showing that a narrower approach can pose limits to the ge…
Final Considerations and Open Scenarios
2016
European river contract experiences demonstrate a growing integration between these contractual agreements and the other instruments of water resources management, and urban and territorial planning. Therefore, river contracts represent innovative places for a new governance of river ecosystems and territories, also in compliance with subsidiarity principle. The twofold nature of these contractual agreements—technical dimension and concertative approach—together with their expected wide evolution, allow to identify river contracts not only as sectoral tools for water resource protection and management, but also as catalysts of a new culture of water, recalling the deep interrelationships ex…
Towards Graphical Query Notation for Semantic Databases
2015
We describe a notation and a tool for schema-enabled visual/diagrammatic creation of SPARQL queries over RDF databases. The notation and the tool support both the standard basic query pattern comprising a main query class and possibly linked condition classes and means for aggregate query definition and placing conditions over aggregates including also aggregation of aggregate results. We discuss the applicability of the tool for ad-hoc query formulation in practical use cases.
Wine Tourism and On-Site Wine Sales
2013
The concept of oenotourism first appeared in the 1980s and was really developed in the 1990s although action relating to this type of tourism and vineyard visits had already begun to take place in several viticultural regions. One dimension of wine tourism is linked with the organisation of trips and the reception of visitors. In this aspect, France became a pioneer when the first Route des Vins was created in 1934 in Burgundy, followed by the Routes des Vins (wine roads) of Alsace and Champagne in 1953. This model was adopted and enhanced in Europe, followed by other great viticultural regions of the world, in particular the United States (Robert Mondavi’s objective was to educate the publ…
Keynote Paper: Data Mining Researcher, Who is Your Customer? Some Issues Inspired by the Information Systems Field
2006
Data mining as an applied research field is still causing great expectations among organizations which want to raise the utility they are getting from their huge databases and data warehouses. There exist too few success stories about organizations having managed to satisfy even some of those expectations. This situation is very similar to the one inside the information systems (IS) field, especially earlier but even currently. The recent lively debate about the identity of the IS discipline included also the analysis concerning the customers of IS research. Inspired by IS researchers' insights related to the topic, we ask the question "who is our customer?" as data mining researchers. With…
Towards Introducing User Preferences in OLAP Reporting Tool
2012
This paper presents an OLAP reporting tool and an approach for determining and processing user OLAP preferences, which are useful for generating recommendations on potentially interesting reports. We discuss the metadata layers of the reporting tool including our proposed OLAP preferences metamodel, which supports various scenarios of formulating preferences of two different types: schema-specific and report-specific. The process of semantic metadata usage at the stage of formulating user preferences is also considered. The methods for processing schema-specific and report-specific OLAP preferences are outlined.
Semantic-based Merging of RSS Items
2009
Merging XML documents can be of key importance in several applications. For instance, merging the RSS news from same or different sources and providers can be beneficial for end-users in various scenarios. In this paper, we address this issue and explore the relatedness measure between RSS elements. We show here how to define and compute exclusive relations between any two elements and provide several predefined merging operators that can be extended and adapted to human needs. We also provide a set of experiments conducted to validate our approach. © Springer Science+Business Media, LLC 2009.
Relating RSS News/Items
2009
Merging related RSS news (coming from one or different sources) is beneficial for end-users with different backgrounds (journalists, economists, etc.), particularly those accessing similar information. In this paper, we provide a practical approach to both: measure the relatedness, and identify relationships between RSS elements. Our approach is based on the concepts of semantic neighborhood and vector space model, and considers the content and structure of RSS news items. © 2009 Springer Berlin Heidelberg.
