Media and Information in Times of Crisis: The Case of the COVID-19 Infodemic
2021
Media play an important role in informing the public about issues on the political agenda, different opinions, and public statements, thereby establishing and bringing forth new spaces of information flow. One of the media’s main roles in democratic societies is to give publicity to central issues on the political and public agenda, especially in times of crisis. Nevertheless, studies have found that, in times of crisis, the public and the media tend to “rally ’round the flag,” leading to significant decreases in their criticality, alongside (almost) unreserved support for nation(al) or region(al) leaders. This paper aims to bridge the gap between both media and communication studies and ge…
Geometric and conceptual knowledge representation within a generative model of visual perception
1989
A representation scheme of knowledge at both the geometric and conceptual levels is offered which extends a generative theory of visual perception. According to this theory, the perception process proceeds through different scene representations at various levels of abstraction. The geometric domain is modeled following the CSG (constructive solid geometry) approach, taking advantage of the geometric modelling scheme proposed by A. Pentland, based on superquadrics as representation primitives. Recursive Boolean combinations and deformations are considered in order to enlarge the scope of the representation scheme and to allow for the construction of real-world scenes. In the conceptual doma…
Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach
2020
Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empi…
Towards More Efficient Incentives for Agri-environment Measures in Degraded and Eroded Vineyards
2015
Evaluating the economic damage caused by soil erosion is important. In addition to increasing the awareness of the problem among farmers and policy makers, evaluation of the economic damage caused by erosion can promote the implementation of more sustainable soil management practices. In the present study, we describe a new approach to evaluate incentives for the adoption of agri-environment measure (AEM) in degraded and eroded vineyards. To estimate this incentive, the replacement cost (RC) and the loss of income are calculated when the vineyard is managed with conventional tillage versus a cover crop (AEM). Our findings show that the incentive could range from the loss of income due to AE…
Facebook brand community bonding: The direct and moderating effect of value creation behaviour
2019
Abstract The present research deepens in the understanding of brand bonding in Facebook brand communities, drawing on value creation behaviours, the parasocial interaction paradigm and the attachment theory. Building up on these theories, our proposed conceptual model posits a direct relationship between value creation behaviour and brand community bonding, resulting from users’ interactions with other community members. The study also examines the moderating role of value co-creation behaviour on community members’ predispositions to develop emotionally based relationships with brands. The sample of the study consisted of 370 followers of brand Facebook pages and the model was assessed usi…
How to learn a conceptual space
2005
the experiments proposed in the article by steels & belpaeme (s&b) can be considered as a starting point toward a general methodology for the automatic learning of conceptual spaces.
Evaluation to support stakeholder centered design and continuous quality improvement in higher education services
2014
Abstract: Evaluation and self-evaluation procedures are commonly used in educational institutions to measure education services and research performance. This chapter describes the main opportunities that evaluation-based approaches can produce to support processes of design and continuous quality improvement in higher education institutions in the light of recent normative measures in Italy to address quality aspects of education services. Subsequently, a new approach – based on the ServQual conceptual model – that evaluates education services is used to carry out a strategic analysis of education services at the management engineering program at the University of Palermo, Italy.
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…
Incompleteness in Conceptual Data Modelling
2013
Although conceptual data modelers can ”get creative” when designing entities and relationships to meet business requirements, they are highly constrained by the business rules which determine the details of how the entities and relationships combine. Typically, there is a delay in realising which business rules might be relevant and a further delay in obtaining an authoritative statement of these rules. We identify circumstances under which viable database designs can be constructed from conceptual data models which are incomplete in the sense that they lack this “infrastructural” detail normally obtained from the business rules. As such detail becomes available, our approach allows the con…
A consumer-based measurement of tourism innovation
2006
SUMMARY The present paper reviews the innovation literature related to tourism and examines the twin problems of operational definitions and measurement of innovation in the tourism sector. A conceptual model is then proposed by which the most relevant aspects of innovation and the most relevant aspects of the “tourism experience” can be integrated conceptually, and which can guide the development of related operational definitions and measurements and lead to a standardization of, and therefore an ability to aggregate, tourism innovation statistics across products, providers, markets and geopolitical regions. The model first categorizes innovations along two dimensions: an “invention-adopt…
