Semantic Mappings in Description Logics for Spatio-temporal Database Schema Integration
2005
International audience; The interoperability problem arises in heterogeneous systems where different data sources coexist and there is a need for meaningful information sharing. One of the most representive realms of diversity of data representation is the spatio-temporal domain. Spatio-temporal data are most often described according to multiple and greatly diverse perceptions or viewpoints, using different terms and with heterogeneous levels of detail. Reconciling this heterogeneity to build a fully integrated database is known to be a complex and currently unresolved problem, and few formal approaches exist for the integration of spatio-temporal databases. The paper discusses the interope…
Are Facebook brand community members truly loyal to the brand?
2015
Investigates two Facebook brand communities and their relationship with loyalty.Community commitment is associated with community promotion behavior and loyalty.Community promotion behavior is associated with different types of loyalty.User activity in Facebook has little or no effect on brand loyalty. This study examines members of Facebook brand communities and tests the relationships between their commitment to the community and brand loyalty. A conceptual model on the linkages between brand community commitment, community promotion behavior and brand loyalty including attitudinal loyalty, repurchase intention and positive word-of-mouth (WOM) is developed and tested with two samples. Dat…
Application d’un modèle conceptuel à l’analyse de la dynamique hydrométéorologique des crues dans un bassin-versant en milieu tropical humide : cas d…

7 pages; International audience; Application of a conceptual model to analysis of dynamic hydrometeorological flood in a pool - side in tropicalmoist environment : the case of Mono river. The objective of this study is to analyze the dynamics of the basinhydrometeorological and distribution of incoming flood dam Nangbéto to assess the risk of flooding in the lower valley of theriver. The data used are: daily flows of Mono (m3.s-1) and Nangbéto Athiémé, evapotranspiration (mm / day, calculatedaccording to the method Oudin et al., 2005) and the average precipitation over the basin (mm / day) covering the period1988- 2010. The method of spatial interpolation of rainfall tested is that of ordin…
Improving Smart City Design : A Conceptual Model for Governing Complex Smart City Ecosystems
2018
Smart city concept is a viable nominee to solve the dilemmas urbanization creates globally. By means of digital technologies like Internet-of-Things, artificial intelligence and data analytics cities aim to optimize city performances like mobility, environment, security, health care and social services. Furthermore, cities actively endorse usage of digital technologies to foster digitalization and new business innovation to nurture local economy and social well-being. Smart city market is growing, but simultaneously fragmented smart city markets and initiatives face challenges with governance, ecosystem orchestration and continuity. Transformation to smart city is a complex long-term proces…
Modeling Vaccine Allocations in the COVID-19 Pandemic: A Case Study in Australia
2020
Timely allocation and distribution of COVID-19 vaccines on a large scale is a highly complex, dynamic, and context-specific task. The focus of this research on optimizing vaccine allocation is on the downstream part of a COVID-19 vaccine supply chain. Previous research on vaccine supply chains and pandemic supply chains has not fully incorporated the multitude of factors and underlying constraints affecting a vaccine supply chain which can be optimized to mitigate the risk of infection. An effective model is needed to conceptualize the process of the downstream vaccine supply chain to ensure efficient coordination and timely distribution of vaccines to the population. This paper develops a …
Manoeuvring between regulations to achieve locally accepted results : analysis of school meals in Latvia and Finland
2018
Rather than having a consistent food policy, countries often tend to regulate food from the margins of other policy domains such as agricultural, environmental, welfare or educational policies. Regulatory interventions perceive food as an instrument rather than a domain with its own specific set of policy issues and view food provision as an activity to achieve certain economic, social and environmental objectives. This fragments the food policy into disintegrated points of interventions from various policy areas and leaves unregulated voids that can be exploited either to improve or to reduce the effectiveness of the interventions. This article explores interlinkages between fragmented pol…
The formation of dominant voice in issue arenas
2011
Abstract The aim of the present study was to map out required changes to current stakeholder thinking in public relations (PR) research and practice for a better suited model for PR professionals. The concept of issue arenas (Luoma-aho & Vos 2009) was adopted for the future direction of stakeholder thinking. Further, a central aspect of PR management on issue arenas is the division of voice – or indirect power – of different players. It was suggested that gaining a dominant voice in an issue arena would facilitate the attainment of organizational goals. Meaning was considered cental in this process. This thesis, focused, on the formation of dominant voice in issue arenas. Two research quest…
Towards a Great Design of Conceptual Modelling
2020
Humankind faces a most crucial mission; we must endeavour, on a global scale, to restore and improve our natural and social environments. This is a big challenge for global information systems development and for their modelling. In this paper, we discuss on different aspects of conceptual modelling in global environmental context. The paper is the summary of the panel session “The Future of Conceptual Modelling” in the 29th International Conference on Information Modelling and Knowledge Bases. peerReviewed
DEVELOPING A 3D ROAD CADASTRAL SYSTEM: COMPARING LEGAL REQUIREMENTS AND USER NEEDS
2018
Abstract. Road transport has always played an important role in a country’s growth and, in order to manage road networks and ensure a high standard of road performance (e.g. durability, efficiency and safety), both public and private road inventories have been implemented using databases and Geographical Information Systems. They enable registering and managing significant amounts of different road information, but to date do not focus on 3D road information, data integration and interoperability. In an increasingly complex 3D urban environment, and in the age of smart cities, however, applications including intelligent transport systems, mobility and traffic management, road maintenance an…
Adding ‘Sense’ to Conceptual Modeling : An Interdisciplinary Approach
2019
In this paper, our aim is to widen the prevailing foundations of conceptual modeling theories and practices, particularly in the context of information systems development. The approach shifts the focus from the link between a model and the modelled reality to the link between human cognition and the model. Our approach combines theoretical issues of different disciplines relevant to conceptual modeling. We shall make an explicit distinction between individual conceptions and interpersonal concepts and show how this distinction could be utilized to have conceptual models of a better consistency. We wish that this article could also serve as a starting point for a profound scientific discuss…
