Navigating high-choice European political information environments : a comparative analysis of news user profiles and political knowledge
2021
The transition from low- to high-choice media environments has had far-reaching implications for citizens’ media use and its relationship with political knowledge. However, there is still a lack of comparative research on how citizens combine the usage of different media and how that is related to political knowledge. To fill this void, we use a unique cross-national survey about the online and offline media use habits of more than 28,000 individuals in 17 European countries. Our aim is to (i) profile different types of news consumers and (ii) understand how each user profile is linked to political knowledge acquisition. Our results show that five user profiles – news minimalists, social m…
Ontological levels in the knowledge management field
2013
The purpose of this study is to examine the relationship between knowledge and reality in the field of management, highlighting the importance of ontological support in the formation of knowledge. The empirical study establishes those ontological levels in large Spanish firms. The article underlines the importance of ontological support and of practice carried out in forming knowledge, and reviews different approaches. The empirical study identifies, via an exploratory factor analysis, the ontological supports of knowledge in large Spanish firms, going on to apply a confirmatory factor analysis that shows the fit of the factors obtained from the sample. The discussion carried out suggests t…
Semantics driven interaction using natural language in students tutoring
2007
The aim of this work is to introduce a semantic integration between an ontology and a chatbot in an Intelligent Tutoring Systems (ITS) to interact with students using natural language. The interaction process is driven by the use of a purposely defined ontology. In the ontology two types of conceptual relations are defined. Besides the usual relations, which are used to define the domain's structure, another type of relation is used to define the navigation schema inside the ontology according to the need of managing uncertainty. Uncertainty level is related to student knowledge level about the involved concepts. In this work we propose an ITS for the Java programming language called TutorJ…
Traitement 3D de nuages de points basé sur la connaissance
2013
The modeling of real-world scenes through capturing 3D digital data has proven to be both useful andapplicable in a variety of industrial and surveying applications. Entire scenes are generally capturedby laser scanners and represented by large unorganized point clouds possibly along with additionalphotogrammetric data. A typical challenge in processing such point clouds and data lies in detectingand classifying objects that are present in the scene. In addition to the presence of noise, occlusionsand missing data, such tasks are often hindered by the irregularity of the capturing conditions bothwithin the same dataset and from one data set to another. Given the complexity of the underlying…
Transparency-by-design: What is the role of open data portals?
2021
Abstract Transparency in the public sector is one of the most important topics of the current debates on accountable, participatory, and responsive governance. An open government addresses these major topics and aims to encourage the relationships and flows of information between involved stakeholders. This article explores the role of open data portals in supporting these efforts and provides findings regarding the features in the design of these data infrastructures. On the basis of evidence from the concept of transparency-by-design, we argue that transparency is facilitated by open data portals and their features enabling to work with datasets. We therefore propose the list of the categ…
What Is Regional in Regional Clusters? The Case of the Globally Oriented Oil and Gas Cluster in Agder, Norway
2012
This paper focuses on the question to what extent knowledge sources in regional clusters stimulate the innovation activity of cluster firms. In doing so we contribute to the literature by combining two analytical approaches: by (1) distinguishing firms dominated by different innovation modes; and (2) differentiating between inter-organizational linkages and open knowledge environments as two distinct knowledge sources. Based on data from the Agder equipment supplier industry we demonstrate that mobility of labour, local buzz and inter-organizational linkages are key regional knowledge sources, but clearly more so for some types of firms than others.
Diversification and performance in the mobile app market: The role of the platform ecosystem
2019
Abstract We examine the effect of app developers' product line diversification decision on their performance and shed light on whether the type of platform ecosystem (open versus closed) where they commercialize apps influences this effect. We compare the revenue performance of diversified and specialized developers in Apple's App Store and Google Play. We show that in the Apple's App Store (closed platform) diversified developers always display lower performance than their specialized counterparts. In Google Play (open platform) diversification is beneficial in categories where diversified developers have predominant market share, whereas it is detrimental in categories dominated by specia…
The Open Innovation in Science research field: a collaborative conceptualisation approach
2020
Openness and collaboration in scientific research are attracting increasing attention from scholars and practitioners alike. However, a common understanding of these phenomena is hindered by disciplinary boundaries and disconnected research streams. We link dispersed knowledge on Open Innovation, Open Science, and related concepts such as Responsible Research and Innovation by proposing a unifying Open Innovation in Science (OIS) Research Framework. This framework captures the antecedents, contingencies, and consequences of open and collaborative practices along the entire process of generating and disseminating scientific insights and translating them into innovation. Moreover, it elucidat…
OWL Orthogonal Extension
2012
It is critical for knowledge bases to capture the reality in direct and intuitive way. OWL ontology language was designed for this goal. In this paper we study the limitations of the OWL open world semantics for the task of knowledge capture and retrieval. We propose a new mechanism based on the closed world semantics that alleviates part of the limitations. Further we describe a system where both OWL and the new mechanisms interoperate together. Finally, we outline some immediate applications and further research directions.
Ambidextrous Leadership, Social Entrepreneurial Orientation, and Operational Performance
2019
In the knowledge era, new forms of organizing and managing firms emerge to adapt to new situations. One such new form of organizational management is ambidextrous leadership. Ambidextrous leadership combines opening leader behaviors, such as promoting creativity, and closing leader behaviors, such as accomplishing objectives and adhering to norms. Thus, the aim is to demonstrate that a social orientation is not at odds with measures of operational performance other than profitability. The purpose of this study is to examine how ambidextrous leadership is linked to social entrepreneurial orientation and how this in turn affects operational performance. This is done through a rigorous review …
