Different drinking motives, different adverse consequences? Evidence among adolescents from 10 European countries
2017
INTRODUCTION AND AIM: This study, which builds on previous research demonstrating that drinking motives are associated with adverse consequences, investigates the associations between drinking motives and non-alcohol-attributed adverse consequences and disentangles alcohol-related and direct effects. DESIGN AND METHOD: On the basis of a sample of 22 841 alcohol-using 13- to 16-year-olds (50.6% female) from Belgium, Denmark, Estonia, Finland, Ireland, Portugal, Scotland, Slovakia, Switzerland and Wales, structural equation models were used to estimate direct and indirect effects. Additionally, differences across countries were tested in a multigroup analysis. RESULTS: The indirect effect (vi…
Foreign sourcing and exporting
2020
The aim in this paper is analysing the role of sourcing intermediate inputs internationally on export decisions, distinguishing whether intermediate are sourced from firms belonging to the same business group or from independent suppliers. To analyse firm’s export decision, we use a specification that also accounts for sunk costs and the accumulated experience in export markets (i.e., foreign markets learning). We consider that importing intermediates might have direct and indirect effects (operating through productivity) on the export participation decision. The direct effects on exporting are isolated once we control for productivity and the effects of belonging to an international group.…
Renal and neurologic effects of cadmium, lead, mercury, and arsenic in children: evidence of early effects and multiple interactions at environmental…
2006
We read with great interest the article by de Burbure et al. (2006) on health effects in children who live near nonferrous smelters in France, the Czech Republic, and Poland. We were especially interested in the inverse relationship found between levels of urinary mercury and serum prolactin. We found a similar result in an Italian multicenter crosssectional survey with adult subjects (Alessio et al. 2002) using a different statistical approach based on regression analysis with mixed linear models. We found that serum prolactin decreased as a function of both urinary mercury and occupational exposure to inorganic mercury (Lucchini et al. 2003). In another study (Carta et al. 2003), our grou…
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…
Interacción entre el Monzón de África Occidental y el clima Mediterráneo en verano: Artículo de revisión
2014
Although in the framework of the global climate research the Mediterranean climate variability and the West African Monsoon (WAM) dynamics have been considered for a long time as “passive” systems, i.e., prone to the influence of large scale ocean and atmospheric variability, over the last decade many studies have been dedicated to the WAM-Mediterranean interaction and the active role of these climate systems has been highlighted. This article presents the WAM-Mediterranean teleconnection through an overview of the recent literature, describing the observational evidences and the dynamical mechanisms underlying this climate teleconnection. The influence of the Mediterranean Sea thermal anom…
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…
The Importance of Recovery from Work in Intensified Working Life
2021
This chapter focuses on intensified working life via the intensified job demands (IJDs) model from the perspective of recovery from work by paying particular attention to the potentially mediating and buffering roles of recovery in the linkages between IJDs and their consequences. In empirical analyses, we examined the buffering role of psychological detachment from work during off-job time in the relationship between intensified job demands and job performance and meaning of work. We found that high psychological detachment, as a recovery experience, buffered against work intensification over time in relation to job performance and meaning of work. Thus, good detachment from work during of…
Uptake of Acetylcholine by Bean Hypocotyl Hooks
1978
Summary The uptake of acetylcholine by etiolated hypocotyl hooks of beans ( Phaseolus vulgaris L.) is influenced by light and the pH-value of the incubation medium. Acetylcholine is hydrolysed up to 90 % during the uptake. The hydrolysis is inhibited by pH-value lower than 6.0 and by eserine, an inhibitor of the acetylcholinesterase. The high amount of hydrolysis is a serious problem in experiments involving acetylcholine and necessitates the inclusions of adequate controls without which direct effects of acetylcholine cannot be distinguished from reactions of its metabolic products.
Linking Economic Stress to Marital Quality Among Finnish Marital Couples
1998
Structural equation modeling was used to test the mediators of economic circumstances on marital quality using a sample of married or cohabiting 36-year-old Finnish men ( n = 133) and women ( n = 117). The model tested was an adapted version of the model presented by Conger, Ge, and Lorenz. For the men, the results were consistent with the proposed model: Poor employment status caused economic strain and affected the lives of the men to the extent that current economic strain increased expected financial strain, leading to greater depression and greater hostility in the marriage, both of which, in turn, predicted poor marital quality. For the women, poor economic circumstances and, in part…
Internet banking loyalty: evaluating the role of trust, satisfaction, perceived risk and frequency of use
2011
This paper analyses the role of satisfaction, trust, frequency of use and perceived risk as antecedents of consumer loyalty to banking websites. While the literature usually focuses on the direct effects of these variables, special attention is paid here to evaluate their moderating effects on the relationship between satisfaction and loyalty. The results from a sample of 254 Spanish users of Internet banking services show that while satisfaction correlates positively with loyalty, the effect is significantly less intense with high levels of perceived risk. The results are similar for trust, which correlates more positively with high levels of perceived risk, but also when Internet banking …
