Exploiting system fluctuations. Differential training in physical prevention and rehabilitation programs for health and exercise

2010

Background. Traditional causal modeling of health interventions tends to be linear in nature and lacks multidisciplinarity. Consequently, strategies for exercise prescription in health maintenance are typically group based and focused on the role of a common optimal health status template toward which all individuals should aspire. Materials and methods. In this paper, we discuss inherent weaknesses of traditional methods and introduce an approach exercise training based on neurobiological system variability. The significance of neurobiological system variability in differential learning and training was highlighted. Results. Our theoretical analysis revealed differential training as a meth…

Impact of cause‐related marketing on consumer advocacy and cause participation: A causal model based on self‐reports and eye‐tracking measures

Cognitive and Affective Causes of Consumer Dissatisfaction With the Hospitality Encounter

2009

Causality attributions, equity, and affection used to explain satisfaction have received special attention in the literature on dissatisfaction and complaining behavior. In this study we examine the contribution these three antecedents make to consumer dissatisfaction. A causal model has been constructed to examine the effect of these variables on dissatisfaction in a sample of 345 individuals who have had an unsatisfactory experience in a restaurant. The results show that attributions, inequity, and negative affections have a significant, direct and positive influence on the level of dissatisfaction, with attribution as the most influential explanatory variable.

Using a brief questionnaire to assess the overall perception of basketball spectators

2014

Purpose – The purpose of this paper is twofold. The first aim is to obtain a valid and reliable instrument for the holistic analysis of sporting events, and the second is to test a causal model in which future intentions depend on spectators’ perceptions of quality, satisfaction, and value of these events. Design/methodology/approach – A total of 493 spectators of a professional basketball team in the Spanish ACB league responded to a survey to measure the overall performance of the sporting event service. Exploratory factor analysis and further confirmatory factor analysis using structural equation models provides the methodology for testing the reliability and validity of the instrument.…

Value antecedents in relationship between tourism companies

2014

Purpose – In the context of relationship marketing, identifying the elements that contribute to creating value for companies has become essential for managing customer satisfaction and retention. The literature has focused on business-to-end consumer relationships and there are few contributions in the business-to-business context, especially in the tourism industry. The aim of this study is to analyze the process of relationship value creation between tourism companies from the more relevant antecedents proposed in the literature: relationship benefits, long-term orientation and attitude towards the main provider. Design/methodology/approach – A survey was conducted with 309 travel agency…

Using meta-analytic path analysis to test theoretical predictions in health behavior: An illustration based on meta-analyses of the theory of planned…

2016

Abstract Objective Synthesizing research on social cognitive theories applied to health behavior is an important step in the development of an evidence base of psychological factors as targets for effective behavioral interventions. However, few meta-analyses of research on social cognitive theories in health contexts have conducted simultaneous tests of theoretically-stipulated pattern effects using path analysis. We argue that conducting path analyses of meta-analytic effects among constructs from social cognitive theories is important to test nomological validity, account for mediation effects, and evaluate unique effects of theory constructs independent of past behavior. We illustrate o…

Extended causal modeling to assess Partial Directed Coherence in multiple time series with significant instantaneous interactions.

2010

The Partial Directed Coherence (PDC) and its generalized formulation (gPDC) are popular tools for investigating, in the frequency domain, the concept of Granger causality among multivariate (MV) time series. PDC and gPDC are formalized in terms of the coefficients of an MV autoregressive (MVAR) model which describes only the lagged effects among the time series and forsakes instantaneous effects. However, instantaneous effects are known to affect linear parametric modeling, and are likely to occur in experimental time series. In this study, we investigate the impact on the assessment of frequency domain causality of excluding instantaneous effects from the model underlying PDC evaluation. M…

Conceptualización y medición del valor percibido: consensos y controversias

2019

[ES] Estudiar el concepto Valor resulta ser necesario y útil en Marketing por ser un concepto endémico para la disciplina y relevante para la profesión. Sin embargo, a pesar de décadas de investigación, la doctrina se lamenta de un cierto círculo vicioso sobre las dificultades conceptuales y de medición del Valor. Este trabajo revisa estas dificultades y las categoriza en torno a acuerdos y controversias, evidenciando sus efectos en la compleja red nomológica construida a lo largo de los años en torno al Valor. Además, explora empíricamente tres modelos causales de relaciones entre dimensiones de Valor, Satisfacción y Lealtad, testados con PLS sobre una muestra de 340 clientes de hotel. Los…

Characterizing the Theory of Mind Network in Schizophrenia Reveals a Sparser Network Structure

2021

AbstractImpaired social functioning is a hallmark of schizophrenia and altered functional integration between distant brain regions are expected to account for signs and symptoms of the disorder. The functional neuroarchitecture of a network relevant for social functioning, the mentalizing network, is however poorly understood. In this study we examined dysfunctions of the mentalizing network in patients with schizophrenia compared to healthy controls via dynamic causal modelling and an interactive social decision-making game. Network characteristics were analyzed on a single subject basis whereas graph theoretic metrics such as in-degree, out-degree and edge-connectivity per network node w…

Conflicto familia-trabajo, autoeficacia y cansancio emocional: un análisis de los efectos longitudinales

2015

A partir del modelo revisado Demandas-Recursos Laborales (2008) este artículo pone a prueba dos objetivos: primero, analizar la relación entre el conflicto trabajo-familia y el agotamiento emocional a través del tiempo y, segundo, identificar el papel de la autoeficacia profesional en esta relación. Se trata deun estudio longitudinal con dos recogidas de datos separados por un año en una muestra de militaresespañoles (n = 242). Se ponen a prueba tres modelos sobre la relación longitudinal entre el conflicto trabajo-familia y el cansancio emocional: el modelo causal normal, el modelo causal reverso y el modelo causal recíproco. A su vez, para probar el papel de la eficacia profesional en la …
