Emotional Intelligence and Social Support: Two Key Factors in Preventing Occupational Stress during COVID-19
2021
Emotional intelligence (EI) and social support are among the most investigated hypothesized variables that affect stress at work. The current study aims to evaluate the direct association between EI and occupational stress and its indirect relationship mediated by three sources of social support during the spread of the COVID-19. The total sample was composed of 367 individuals (53.7% males), aged from 20 to 68 (M = 37.84, SD = 10.39), who filled out an online questionnaire. A mediation analysis was performed to test the hypothesized relationships. Our findings showed that EI has a direct effect on psychological effects and an indirect effect on almost all the facets of occupational stress.…
Life satisfaction and the mediating role of character strengths and gains in informal caregivers
2021
WHAT IS KNOWN ON THE SUBJECT?: The role of informal caregiver can have both negative and positive consequences for a person's well-being. The main theoretical framework for explaining these consequences is the stress process model, which considers contextual variables, stressors and mediating/moderating factors. The latter are psychosocial factors such as coping strategies, personal mastery, social support or beliefs and values which may influence caregiver well-being. The perception of gains in caregiving has also been proposed as a mediating variable since it may act as a coping strategy. However, few studies have examined values and perceived gains as mediating variables with life satisf…
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…
Theoretical Study of Catalytic Efficiency of a Diels–Alderase Catalytic Antibody: An Indirect Effect Produced During the Maturation Process
2007
The Diels–Alder reaction is one of the most important and versatile transformations available to organic chemists for the construction of complex natural products, therapeutics agents, and synthetic materials. Given the lack of efficient enzymes capable of catalyzing this kind of reaction, it is of interest to ask whether a biological catalyst could be designed from an antibody-combining site. In the present work, a theoretical study of the different behavior of a germline catalytic antibody (CA) and its matured form, 39 A-11, that catalyze a Diels–Alder reaction has been carried out. A free-energy perturbation technique based on a hybrid quantum-mechanics/molecular-mechanics scheme, togeth…
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…
Trade and Interlegality
2019
The idea that the WTO legal system and its institutional bodies (especially the judicial branch) have developed a single-sided ides of what is good and would attempt to impose a deep-rooted liberalization agenda on the rest of world is hardly corroborated by an empirical analysis. Quite the contrary, recourse to a series of legal techniques has made it possible to leave open a space for reciprocal understanding and debate with other circuits of legality.
Self-Selection into Exports: Productivity and/or Innovation?
2009
Abstract Recent research has related the firm decision to export with firm innovation activities and productivity. The aim of this paper is to disentangle the direct and indirect links through which self-selection into exports, coming both from productivity and innovation, may operate. For this purpose we use Spanish manufacturing firm data for the period 1990–2000, drawn from the Encuesta sobre Estrategias Empresariales. The main results we obtain can be summarized as follows. First, there is a self-selection into exports direct effect coming from productivity. Second, there is also a self-selection indirect effect into exports stemming from productivity to the probability of exporting thr…
The role of self-compassion in the relationship between attachment, depression, and quality of life.
2019
Abstract Background Self-compassion may be shaped by early attachment experiences, and has been linked to mental health and well-being. This study examined the role of two distinct features of self-compassion, self-warmth and self-coldness, in the relationship between attachment insecurity and depression as well as quality of life in a general population sample in Germany. Methods Participants (N = 2,253; 53.4% female, Mage 50 years) completed the Self-Compassion Scale (SCS), Adult Attachment Scale (AAS), Beck Depression Inventory-Fast Screen (BDI-FS), and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Mediation analysis was used to…
