Analysing Intercultural Dialogue Through Conceptual Densities
2020
In this chapter, we exemplify our methodological approach to analysing ‘densities’ of interrelated concepts in European education policy documents. We scrutinize instances where many of the core concepts of intercultural dialogue appear in the documents at the same time. Four core educational themes and four longer excerpts from the selected policy documents are examined in more detail. The chosen documents deal especially with multilingualism, migration, history teaching, and lifelong learning. The analysis of the conceptual densities in the chosen excerpts indicates how the meanings of intercultural dialogue are constructed through the conceptual frameworks and co-occurrences of their cor…
On the rhetoric and relevance of IS research paradigms: a conceptual framework and some propositions
2003
This paper discusses the relevance of IS research with respect to the rhetoric associated with three IS research paradigms in use - positivism, constructivism/interpretivism and critical research. The discussion is framed in terms of the following dimensions: ontological, epistemological and methodological assumptions, relationship between theory and practice, and the role of the researcher in the research process. Based on this discussion, the authors propose a theoretical framework to study the relationship of the espoused assumptions of a researcher's perspective with the degree of relevance of their knowledge claims to various stakeholders. In conclusion, some key propositions are eluci…
@DMOs Promote Hotel Occupancy in Tourist Destinations: An Abstract
2017
Destination marketing organizations (DMOs) are aware of Twitter’s relevance, and they have now integrated Twitter into their own websites (Luna-Nevarez and Hyman 2012). Because of their growing practical importance, social media have become strong allies for tourism destinations. Social media are used by both tourists and providers (Leung et al. 2013), so research is needed to show social media’s direct contribution to the tourism sector. To improve our knowledge of the effect of social media in tourism, this study examines how DMOs’ use of Twitter affects hotel occupancy in tourist destinations. Our conceptual framework presents a model of the links between predictors of tourist occupancy …
A qualidade do intercâmbio líder-membro (LMX) e o clima psicológico: Uma análise longitudinal das suas relações recíprocas
2014
Although the relationship between climate and leadership has been taken into account from different research and theoretical approaches, there is a lack of effort in the development of conceptual framework to understand the relationship between the development processes in both constructs. Grounding on the interactionist approach to the formation of climate and the Leader Member Exchange in leadership, Kozlowski and Doherty (1989) developed a conceptual framework that specifies the theoretical mechanisms linking both constructs. The lack of longitudinal designs hinders the possibility to test causal relationship between both constructs. The main objective of the present paper was to test a …
Innovation capabilities: What are their characteristics and how can they be conceptualized?
2017
Purpose – It has been argued that firms may utilize their resources and capabilities through the development of innovations in the form of new products, services or processes, and empirical research has confirmed that there is a positive relationship between the implementation of innovation activities and future performance of firms. Some firms prove to be better at reproducing innovation success than other firms, and the capacity to do so can be framed as an innovation capability. However, the term innovation capability is ambiguously treated in extant literature. There exist several different definitions of the concept and the distinction between innovation capabilities and other types of…
An algebra for the manipulation of conceptual spaces in cognitive agents
2013
According to Gärdenfors, the theory of conceptual spaces describes a level of representation present in some cognitive agents between a sub-conceptual and a symbolic level of representation. In contrast to a large part of contemporary philosophical speculation on these matters for which concepts and conceptual content are propositional, conceptual spaces provide a geometric framework for the representation of concepts. In this paper we introduce an algebra for the manipulation of different conceptual spaces in order to formalise the process whereby an artificial agent rearranges its internal conceptual representations as a consequence of its perceptions, which are here rendered in terms of …
Seismic Performance of Earthquake-Resilient RC Frames Made with HSTC Beams and Friction Damper Devices
2021
Seismic behavior of RC frames with hybrid steel-trussed concrete beams is affected by panel zone damage due to a large amount of longitudinal reinforcement. Here the seismic efficiency of innovative frames characterized by friction damper devices (FDDs) at beam-to-column connections is compared against traditional frame. Three configurations are investigated: FDDs alone; FDDs with column-to-foundation connections having preloaded threaded bars and disk springs; FDDs with self-centering friction devices. Non-linear analyses show that FDDs alone prevent plastic hinge formation at beam ends and beam–column joint damage. FDDs with self-centering friction devices effectively limit both peak and …
Effects of pressure on the local atomic structure of CaWO4 and YLiF4: mechanism of the scheelite-to-wolframite and scheelite-to-fergusonite transitio…
2003
The pressure response of the scheelite phase of CaWO4 (YLiF4) and the occurrence of the pressure induced scheelite-to-wolframite (M-fergusonite) transition are reviewed and discussed. It is shown that the change of the axial parameters under compression is related with the different pressure dependence of the W-O (Li-F) and Ca-O (Y-F) interatomic bonds. Phase transition mechanisms for both compounds are proposed. Furthermore, a systematic study of the phase transition in 16 different scheelite ABX4 compounds indicates that the transition pressure increases as the packing ratio of the anionic BX4 units around the A cations increases.
Automated detection of patient movement during a CBCT scan based on the projection data.
2015
Objectives To develop an automated procedure to detect patient motion on the projection images acquired during a cone beam computed tomography (CBCT) scan and to evaluate the method's feasibility on small real-world CBCT images in relation to visual assessment. Methods Based on optical flow theory, software was developed using the sequence of the projection images of a CBCT machine for automated detection of patient motion. Averaged acceleration vectors were used as measurement data and compared with visual assessment of the projection images displayed as video. Seventy-nine CBCT data sets (small field-of-view: 40 mm) from our patient database were selected in a sequential fashion and evalu…
Elementary Newtonian Mechanics
2010
This chapter deals with the kinematics and the dynamics of a finite number of mass points that are subject to internal, and possibly external, forces, but whose motions are not further constrained by additional conditions on the coordinates. Constraints such as requiring some mass points to follow given curves in space, to keep their relative distance fixed, or the like, are introduced in Chap. 2. Unconstrained mechanical systems can be studied directly by means of Newton’s equations and do not require the introduction of new, generalized coordinates that incorporate the constraints and are dynamically independent. This is what is meant by “elementary” in the heading of this chapter — thoug…
