Research Directions of OLAP Personalizaton
2011
In this paper we have highlighted five existing approaches for introducing personalization in OLAP: preference constructors, dynamic personalization, visual OLAP, recommendations with user session analysis and recommendations with user profile analysis and have analyzed research papers within these directions. We have provided an evaluation in order to point out (i) personalization options, described in these approaches, and its applicability to OLAP schema elements, aggregate functions, OLAP operations, (ii) the type of constraints (hard, soft or other), used in each approach, (iii) the methods for obtaining user preferences and collecting user information. The goal of our paper is to syst…
OLAP Personalization with User-Describing Profiles
2010
In this paper we have highlighted five existing approaches for introducing personalization in OLAP: preference constructors, dynamic personalization, visual OLAP, recommendations with user session analysis and recommendations with user profile analysis and have analyzed research papers within these directions. We have pointed out applicability of personalization to OLAP schema elements in these approaches. The comparative analysis has been made in order to highlight a certain personalization approach. A new method has been proposed, which provides exhaustive description of interaction between user and data warehouse, using the concept of Zachman Framework [1, 2], according to which a set of…
The Unbalanced Linguistic Aggregation Operator in Group Decision Making
2012
Published version of an article in the journal: Mathematical problems in engineering. Also available from Hindawi: http://dx.doi.org/10.1155/2012/619162 Many linguistic aggregation methods have been proposed and applied in the linguistic decision- making problems. In practice, experts need to assess a number of values in a side of reference domain higher than in the other one; that is, experts use unbalanced linguistic values to express their evaluation for problems. In this paper, we propose a new linguistic aggregation operator to deal with unbalanced linguistic values in group decision making, we adopt 2-tuple representation model of linguistic values and linguistic hierarchies to expres…
THE THEORETICAL ASPECTS OF WELL-BEING IN THE CONTEXT OF LIFELONG LEARNING
2017
In 2006 the European Parliament and European Union Council has defined eight key competences for lifelong learning, necessary for personal fulfillment and development, active citizenship, social inclusion and employment. Since the economic crisis of 2008, the world is looking for new ways and methods to ensure the well-fare and reformulate the value of human life. Currently at EU level, one of the most important debates closely connected with the basic context of lifelong learning is on the dimensions of life quality.

Conceptualizing the European multilevel administrative order: capturing variation in the European administrative system
2015
Acknowledging that both analysts and practitioners face problems of meaningful categorization of social order in general, and the European political-administrative system in particular, this article suggests a conceptual frame through which European administrative order may be understood. Providing such a frame is important, because the catalogue of categories of the European Union (EU) polity developed so far fails to acknowledge its administrative dimension. Given that the ongoing political transformation in the EU implies ever more administrative interaction between political levels in order to coordinate, manage and implement policies, this administrative dimension becomes ever more imp…
Conceptualizing Online Discussion Value: A Multidimensional Framework for Analyzing User Comments on Mass-Media Websites
2013
This chapter provides a micro-framework for analyzing the quantity and quality of online user comments on mass-media websites. On one dimension, news factors of news items and discussion factors of existing user comments are assumed to indicate the relevance of participating in online discussions. On a second dimension, specific motivational, social, and design factors are influential when reconstructing users’ decisions to participate in online discussions and when analyzing the content of online user comments. The two dimensions in combination describe the discussion value of news items. Potential applications of this framework on other forms of interpersonal communication are discussed.
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…
