Conceptualizing and Measuring the Perceived Value of an Arts Venue as Applied to Live Performance
2008
International audience; This paper mobilizes the concept of value to investigate the influence of physical surroundings on artistic experiences. First the literature on value is reviewed to ascertain just how useful the concept is for understanding the physical environment. The use of the concept supplements other research perspectives on the issue of physical surroundings (sensorial marketing, appropriation). There follows a presentation of the various stages in constructing a scale of perceived value applied to live performances. The paper concludes with a discussion of results (contributions, management implications, research limits, and avenues for further inquiry).
The inter-rater and intra-rater reliability of the Actual Aquatic Skills Test (AAST) for assessing young children’s motor competence in the water
2021
As children’s actual aquatic skills are important for the prevention of drowning as well as their engagement in lifelong aquatic physical activity, researchers and practitioners should be able to assess this vital concept accurately and reliably. Therefore, this study aimed to investigate the inter-rater and intra-rater reliability of the Actual Aquatic Skills Test (AAST), consisting of 17 different test items for the assessment of young children’s motor competence in the water. Six raters received a training and evaluation session on scoring the AAST, after which five of them assessed four test videos (of various children (n = 38) performing the test items) twice, with one to t…
Galaxy clustering: a point process
2016
El 'clustering' de galàxies és l'agregació de galàxies en l'universe produida per la força de la gravetat. Les galàxies tendeixen a formar estructures de major tamany tal com 'clusters' o filaments que formen la xarxa còsmica ('Cosmic Web'). Aquesta Estructura a Gran Escala de l'Univers es pot entendre com el resultat de la distribució de galàxies, un procés en el qual totes les galàxies estan subjectes a forces comuns i comparteixen propietats universals. L'anàlisis d'aquesta distribució es pot realitzar amb técniques de processos puntuals, l'estudi de configuracions de punts sobre un marc. En aquesta tesi fem servir aquesta branca de la estadística en tres approximacions diferents: els es…
L'Oscillation de Madden-Julian et la variabilité pluviométrique régionale en Afrique Subsaharienne
2007
The role of the Madden-Julian Oscillation ("MJO") on rainfall variability in Sub-Saharan Africa is examined, based on daily rain-gauge records and the NCEP-DOE AMIP-II reanalyses. The convective and dynamical signal associated with the MJO is extracted using two differing methodologies, the BMRC daily indices (Wheeler & Hendon 2004) on the one hand, and a Local Mode Analysis ("LMA", Goulet & Duvel 2000) on the other hand. The temporal variability of the MJO (in terms of period, amplitude, seasonality and location of the convective anomalies) is first analysed. Though the overall amplitude of the signal is not related to El Niño, the oscillations occurring under El Niño (La Niña) conditions …
The 1-way on-line coupled atmospheric chemistry model system MECO(n) – Part 2: On-line coupling with the Multi-Model-Driver (MMD)
2012
A new, highly flexible model system for the seamless dynamical down-scaling of meteorological and chemical processes from the global to the meso-γ scale is presented. A global model and a cascade of an arbitrary number of limited-area model instances run concurrently in the same parallel environment, in which the coarser grained instances provide the boundary data for the finer grained instances. Thus, disk-space intensive and time consuming intermediate and pre-processing steps are entirely avoided and the time interpolation errors of common off-line nesting approaches are minimised. More specifically, the regional model COSMO of the German Weather Service (DWD) is nested on-line into the …
Attitudes toward and motivation for PE: who collects the benefits of the subject?
2014
Background and purpose: Due to attitudinal and motivational aims in the national curriculum, and to lack of research on adolescents' experiences with physical education (PE) in Norway, the purposes of this study were to (1) attain data on attitudes toward PE and self-determined motivation for PE among a representative sample of adolescents (N = 2010) in middle school (grade 8–10/age 13–15) and high school (grade 11–13/age 16–19) in Norway, and (2) to explore the relationship between involvement in movement activities outside school and self-determined motivation in PE. Findings: The results showed that 43% of the adolescents were not happy with how PE is taught in Norwegian schools, and tha…
Interpersonal forgiveness and meaning in life in older adults: The mediating and moderating roles of the religious meaning system
2021
Forgiving others may play an important role in achieving meaning in life as it offers a valuable platform for deliberate moral acts of acceptance of positive affect, behaviour, and cognition towards a transgressor. The aim of this paper was to analyse the relationship between forgiveness and presence, and the search for meaning in life, as well as the mediating role of the religious meaning system in this relationship among older adults. A total of 205 older adults, 112 women and 93 men, participated in the study. The mean age was 72.59. The Transgression-Related Interpersonal Motivations Scale, the Meaning in Life Questionnaire, and the Religious Meaning System Questionnaire were employed …
The b-chromatic number of power graphs
2003
The b-chromatic number of a graph G is defined as the maximum number k of colors that can be used to color the vertices of G, such that we obtain a proper coloring and each color i, with 1 ≤ i≤ k, has at least one representant x_i adjacent to a vertex of every color j, 1 ≤ j ≠ i ≤ k. In this paper, we discuss the b-chromatic number of some power graphs. We give the exact value of the b-chromatic number of power paths and power complete binary trees, and we bound the b-chromatic number of power cycles.
Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV
2018
Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…
Coupling two radar backscattering models to assess soil roughness and surface water content at farm scale
2013
Remote sensing techniques are useful for agro-hydrological monitoring at the farm scale because the availability of spatially and temporally distributed data improves agricultural models for irrigation and crop yield optimization under water scarcity conditions. This research focuses on the surface water content retrieval using active microwave data. Two semi-empirical models were chosen as these showed the best performances in simulating cross and co-polarized backscatter. Thus, these models were coupled to obtain reliable assessments of both soil water content and soil roughness. The use of the coupled model enables one to avoid using roughness measured in situ. Remote sensing images and …
