Populated Places and Conspicuous Consumption: High Population Density Cues Predict Consumers’ Luxury-Linked Brand Attitudes

2021

Population density has been identified as an ecological factor with considerable behavioral implications. The present research aimed to examine whether the mere perception of more (vs. less) populated places can change consumers’ luxury-linked brand attitudes. To this end, we experimentally manipulated consumers’ perceptions of population density using pictorial exposure to high (vs. low) population density cues. The results revealed a significant interaction between manipulated population density and perceived brand luxury on brand attitudes. Specifically, exposure to high rather than low population density cues resulted in more positive (negative) attitudes toward brands deemed to be more…

Task Contexts in Dutch Mathematics Education

2020

This chapter offers a description of task contexts in mathematics education in the Netherlands. International comparative studies show that the Dutch average percentage of mathematics tasks with real-life connections per lesson exceeds any other country by far. This tradition goes back more than 500 years, when the earliest mathematics textbooks in the Dutch language consisted entirely of tasks, in which mathematics was put to use in commercial contexts. In this chapter characteristics of contexts in mathematics tasks in the Netherlands are studied. Underlying frame is the notion of usefulness, which is a perception by students on future practices outside school. A distinction is made betwe…

Relationships between leadership and professionals' job attitudes and perceptions: Comparison of two leadership models

1996

Abstract The aim of this study was to investigate the power of the Average Leadership Style (ALS) and Vertical Dyad Linkage (VDL) models of leadership in explaining relationships between leader's initiating structure behaviour and consideration behaviour, and subordinates' attitudes and perceptions. The considered dependent variables were five facets of job satisfaction, two role stress variables (role conflict and ambiguity), one role strain indicator (job tension), and four dimensions of workteam climate. The relationships were investigated in two occupational samples comprising 127 family physicians and 155 nurses working in 28 Primary Health Care Teams. Within and between analysis (WABA…

Support Vector Machines for Crop Classification Using Hyperspectral Data

2003

In this communication, we propose the use of Support Vector Machines (SVM) for crop classification using hyperspectral images. SVM are benchmarked to well–known neural networks such as multilayer perceptrons (MLP), Radial Basis Functions (RBF) and Co-Active Neural Fuzzy Inference Systems (CANFIS). Models are analyzed in terms of efficiency and robustness, which is tested according to their suitability to real–time working conditions whenever a preprocessing stage is not possible. This can be simulated by considering models with and without a preprocessing stage. Four scenarios (128, 6, 3 and 2 bands) are thus evaluated. Several conclusions are drawn: (1) SVM yield better outcomes than neura…

Abstract This article contains intensity and aversiveness ratings of electrical stimuli and data on electrodermal activity (skin conductance level and skin conductance response) during an implicit conditioning procedure. Further, answers from a questionnaire on contingency awareness are provided. The experiment consisted of three phases. In the acquisition, two types of visual stimuli (CS+ and CS-) were coupled to weakly and moderately painful electrical stimuli presented to the participants’ (N = 48) dominant hand. In the test phase, after both CS+ and CS- only the weakly painful electrical stimuli were presented. In the contingency test phase, no more electrical stimuli were presented and…

Contingent Valuation Measurement for Staging the Olympic Games: The Failed Bid to Host the 2018 Winter Games in Munich

2020

In the past decade, well-planned bids for hosting Olympic Games failed due to a sudden lack of a support by the population. Therefore, we study both the determinants of people’s willingness to pay (WTP) to host the 2018 Winter Olympic Games in Munich and the changes of respondents’ attitudes and WTP over time. The results from three surveys in 2009, 2010 and 2011 demonstrate that both the perception of the public benefit of the Olympic Games and the general interest in sport have a positive influence on WTP. Moreover, attitudes vary over time, indicating that external factors influence the population’s evaluations of, and appreciation for, hosting of Olympic Games (e.g. media reports). In c…

The functional-psychological continuum in the cognitive image of a destination: A confirmatory analysis

2009

Abstract This paper analyses the cognitive component of the image of a destination from a dual perspective. Firstly, we study its composition by positing three positions on a continuum: functional, mixed and psychological, which are analysed using confirmatory factor analysis. Secondly, we study the influence of these components on tourists' overall image of the destination and on their future behaviour intentions, using structural equation analysis. The results show that the psychological and functional components exercise the greatest influence on the overall image of the destination. Overall image was found to influence future behaviour intentions consistently, while the functional compo…

Contrast perception in digitized panoramic radiographs compared with their film-based origin

2002

Abstract Objectives. We sought to compare the visual image quality of film-based and digitized panoramic radiographs through use of a hole-containing test wedge. Study Design. An aluminum wedge containing 100 cells, of which 90 were given shallow holes, was exposed in the film-based Orthophos CD panoramic unit. Two radiographs subjectively exhibiting optimum contrast were selected. Films were digitized with a charge-coupled device flatbed scanner at 300 dpi. Films and digitized images were rated cellwise by 2 similar groups of 50 observers each with respect to spot perception. Results. The mean sensitivity was 0.26 ± 0.09 for film and 0.20 ± 0.07 for digitized images (P =.000), with a prono…

On Activity and Passivity in Perception: Aristotle, Philoponus, and Pseudo-Simplicius

2014

Ancient and late ancient theories of perception are often described by a generalisation according to which Aristotle held a passive theory whereas Plato, the Platonists and the Neoplatonists supposed perception to be something active. I shall argue that, despite this general difference, there are important points of convergence in the theories of Aristotle and his Neoplatonic commentators. First, the notion of activity is important for Aristotle’s theory as well. Perception not only is an activity (energeia) for Aristotle. It is a perfect activity, the perfection of which is the activity itself and is thus not dependent on an external product. Further, the reception of forms without matter …

How Physical Education Teachers’ Interpersonal Behaviour is Related to Students’ Health-Related Quality of Life

2019

Grounded in self-determination theory (SDT), this cross-sectional study tested relations of students’ perceptions of autonomy-supportive and controlling behaviour from teachers in physical education with students’ health-related quality of life (HRQoL), and the potential role of students’ perceived need satisfaction and need frustration as a mediator of these relationships. School students (N = 1031) completed self-report measures of perceived autonomy support, perceived teachers’ controlling behaviour, students’ need satisfaction and need frustration, and HRQoL. Results indicated that students’ perceptions of autonomy support from teachers was positively associated with HRQoL through need …
