Personality, social support and affective states during simulated microgravity in healthy women
2009
This study investigated the time-course of stress and recovery states and their relations to social support and personality traits in healthy women during a long-term head-down tilt bed rest. Personality, social support and affective states were assessed in 16 women exposed to simulated microgravity for a 60-day duration involving three stages: a 20-day baseline control period (BDC), a 60-day head-down tilt bed rest (HDT) and a 20-day post-HDT ambulatory recovery period (R+). Participants were divided into two groups: an exercise (Exe, n = 8) and a control group (Ctl, n = 8). All the participants experienced significantly more stress during the HDT period. But exercise did not improve the i…
Are You Able to Trust Me? Analysis of the Relationships Between Personality Traits and the Assessment of Attractiveness and Trust
2021
Behavioral and neuroimaging studies show that people trust and collaborate with others based on a quick assessment of the facial appearance. Based on the morphological characteristics of the face, i.e., features, shape, or color, it is possible to determine health, attractiveness, trust, and some personality traits. The study attempts to indicate the features influencing the perception of attractiveness and trust. In order to select individual factors, a model of backward stepwise logistic regression was used, analyzing the results of the psychological tests and the attractiveness and trust survey. Statistical analysis made it possible to select the most important personality traits related…
The moderator role of followers’ personality traits in the relations between leadership styles, two types of task performance and work result satisfa…
2014
Authentic leadership is changing our understanding of what makes good leadership. However, few studies have explored how followers’ individual differences and the nature of the task they perform affect its relation to followers’ work outcomes. We examine the moderator role of two core task types (intellective vs. generative) and two personality traits (conscientiousness and emotional stability) in the relationship between two leadership feedback styles (authentic vs. transactional) and task performance or work result satisfaction in a two-wave experiment. The sample consisted of 228 participants enrolled in an organizational psychology course, 34% of whom had work experience. Our results sh…
Efectos de la inteligencia emocional sobre la intención y la autoeficacia emprendedora
2014
Past studies associated emotional intelligence with positive workplace outcomes, such as job performance and job satisfaction. However, to date, the relationship between emotional intelligence and individual differences in entrepreneurship has been scarcely examined. In this study, the contribution of emotional intelligence dimensions to entrepreneurial potential is explored, controlling for the influence of personality traits and demographic variables. Using a sample of 394 participants, it has been tested, by means of multiple hierarchical regression analyses, the mediating role of entrepreneurial self-efficacy in the relationship between emotional intelligence dimensions and the intentio…
Effects of emotional intelligence on entrepreneurial intention and self-efficacy
2014
Estudios previos relacionan la inteligencia emocional con resultados positivos en el puesto de trabajo, tales como el desempeño y la satisfacción laboral. Sin embargo, la relación entre la inteligencia emocional y las diferencias individuales en emprendimiento han sido escasamente examinadas. En el presente estudio se analiza el efecto de las dimensiones de la inteligencia emocional sobre el potencial emprendedor, tras controlar la influencia de los rasgos de personalidad y variables demográficas. Concretamente, con una muestra de 394 participantes, por medio de análisis de regresión jerárquica, se pone a prueba el rol mediador de la auto-eficacia emprendedora en la relación entre las dimen…
Evidence for a conserved queen-worker genetic toolkit across slave-making ants and their ant hosts
2021
AbstractThe ecological success of social Hymenoptera (ants, bees, wasps) depends on the division of labour between the queen and workers. Each caste is highly specialised in its respective function in morphology, behaviour and life-history traits, such as lifespan and fecundity. Despite strong defences against alien intruders, insect societies are vulnerable to social parasites, such as workerless inquilines or slave-making (dulotic) ants. Here, we investigate whether gene expression varies in parallel ways between lifestyles (slave-making versus host ants) across five independent origins of ant slavery in the “Formicoxenus-group” of the ant tribe Crematogastrini. As caste differences are o…
Effects of microplastics on the functional traits of aquatic benthic organisms: A global-scale meta-analysis
2021
Microplastics are widespread in the aquatic environment and thus available for many organisms at different trophic levels. Many scientific papers focus their attention on the study of the effects of microplastics on different species at individual level. Here we performed a global scale meta-analysis focusing our work on the study of the effect of microplastics on the functional traits of aquatic benthic organisms. Overall, microplastics showed a moderate negative effect on the examined functional traits of benthic organisms. Our results show that some crucial functional traits, such as those linked to behaviour and feeding, appear to be unaffected by microplastics. In contrast, traits rela…
QUALITATIVE AND QUANTITATIVE BEHAVIORAL TRAITS IN A COMMUNITY OF FURCOCERCARIAE TREMATODES: TOOLS FOR SPECIES SEPARATION?
2008
Many trematode cercariae show distinct behavioral features, which have commonly been used in species identification in combination with morphological characteristics. However, information regarding cercariae behavior has often not been quantified in detail, or it is scattered in the literature, which is why the appropriate level of precision in behavioral identity, particularly in groups of cercariae species showing considerable morphological overlap, has not been properly established. In this study, we investigated one such group, the furcocercariae trematodes, by studying their behavior in a community consisting of 8 species (Diplostomum pseudospathaceum, Ichthyocotylurus variegatus, Coty…
Diuron environmental levels effects on marine nematodes: Assessment of ecological indices, taxonomic diversity, and functional traits
2021
Abstract Coastal marine systems are the most sensitive zones to emerging pollutants. The present study aims to investigate the effect of Diuron on the meiofaunal assemblages, collected from the Bizerte channel (Tunisia). Microcosm experiments were set up using four increasing Diuron concentrations [D1 (10 ng g−1 dry weight (DW)), D2 (50 ng g−1 DW), D3 (250 ng g−1 DW) and (1250 ng g−1 DW)] compared to non-contaminated sediments (controls) and all plots were incubated for 30 days. Our results show that Diuron-supplemented sediments provoked the significant decrease of meiofaunal abundance as well as a change in nematodes' diversity and structure composition. All univariate indices, as well as…
The Role of Motivation, Cognition, and Conscientiousness for Academic Achievement
2013
Based on a cognitive motivational process model of learning, the impact of studying behavior on learning outcome is investigated. First-year students ( N = 488) participated in the study. Two research questions were addressed: (1) Can cognitive-motivational variables and objective study behavior predict individual learning? (2) Which factors drive studying behavior? Results show low to moderate correlations between cognitive-motivational variables and performance. A cluster analysis yielded three profiles: (1) interested learners with high academic self-concept and effort investment; (2) low interest learners with high academic self-concept and low effort investment; and (3) interested lear…
