The Different Role of Mothers' and Fathers' Beliefs in the Development of Adolescents' Mathematics and Literacy Task Values

2015

This study examined how interest and importance values concerning mathematics and literacy develop from grade 7 to grade 9 in comprehensive school and to what extent gender, in addition to mothers’ and fathers’ beliefs about the abilities of individual children, predicts the level of and changes in these values. A total of 206 Finnish students (100 girls, 106 boys) were followed from grade 7 to grade 9, just before an important transition from compulsory comprehensive school to secondary education occurs in the Finnish context. Students’ parents participated in the study when the students were in grade 7. The results of multivariate latent change models showed that interest and importance v…

Supervisor leadership style, employee regulatory focus, and leadership performance: A perspectivism approach

2019

[EN] Drawing on regulatory focus theory, this research proposes that transformational leadership performance depends on followers' circumstances. The analysis of 125 people from two Spanish service firms reveals that, apart from transformational leadership, the presence of academic education, intrinsic job satisfaction and high customer contact, and the absence of family responsibilities, are core conditions for the presence of high leadership performance. The first contribution of this study is the direct inference of follower's regulatory focus from the observation of individuals' circumstances. The second contribution is that leaders should consider followers' circumstances to adopt a su…

The role of parents' and teachers' beliefs in children's self-concept development

2016

This study examined to what extent parents' and teachers' beliefs about children's abilities predict children's self-concept of math and reading ability development during the first grade, and whether these predictions depend on the child's gender and level of performance. One hundred fifty-two children and their parents and teachers were followed across first grade. The results showed, first, that the associations between teachers' beliefs and children's subsequent self-concept of ability depended on the level of the children's performance. Among high-performers, the higher the teachers' beliefs about their students' abilities in reading or in math, the higher the subsequent level of self-…

Religiosity and meditation practice : Exploring their explanatory power on psychological adjustment

2019

There has been increased interest in the relationships between religiosity, meditation practice and well-being, but there is lack of understanding as to how specific religious components and distinct meditation practices could influence different positive and negative psychological adjustment outcomes. The aim of this study was to assess the explanatory power of religious beliefs and the practice of prayer, focused attention (FA), open monitoring (OM), and compassion meditation (CM) on psychological adjustment, taking into consideration a number of practice-related variables such as session length, frequency of practice and lifetime practice. Psychological adjustment was assessed by means o…

Data from: Life history differences in age-dependent expressions of multiple ornaments and behaviors in a lekking bird

2014

Age is a major factor explaining variation in life-history traits among individuals with typical patterns of increasing trait values early in life, maximum trait expression, and senescence. However, age-dependent variation in the expressions of sexually selected traits has received less attention, although such variation underpins differences in male competitive abilities and female preference, which are central to sexual selection. In contrast to previous studies focusing on single traits, we used repeated measures of seven sexually selected morphological and behavioral traits in male black grouse (Tetrao tetrix) to quantify the effects of age and life span on their expressions and quantif…

Data from: Aging parasites produce offspring with poor fitness prospects

2017

Senescing individuals have poor survival prospects and low fecundity. They can also produce offspring with reduced survival and reproductive success. We tested the effect of parental age on the performance of descendants in the nematode Heligmosomoides polygyrus, an intestinal parasite of rodents. We found that offspring of senescing worms had reduced within-host survival and reduced egg shedding over the first month post-infection compared with offspring produced by young parents. These results suggest that declining offspring quality is a component of senescence in parasitic nematodes and might have evolutionary consequences for the optimal schedule of age-dependent investment into reprod…

Data from: Experimental evolution of an emerging plant virus in host genotypes that differ in their susceptibility to infection

2014

This study evaluates the extent to which genetic differences among host individuals from the same species conditions the evolution of a plant RNA virus. We performed a three-fold replicated evolution experiment in which Tobacco etch potyvirus isolate At17b (TEV-At17b), adapted to Arabidopsis thaliana ecotype Ler-0, was serially passaged in five genetically heterogeneous ecotypes of A. thaliana. After 15 passages we found that evolved viruses improved their fitness, showed higher infectivity and stronger virulence in their local host ecotypes. The genome of evolved lineages was sequenced and putative adaptive mutations identified. Host-driven convergent mutations have been identified. Eviden…

Data from: Inbreeding-related trade-offs in stress-resistance in the ant Formica exsecta

2014

Inbred individuals and populations are predicted to suffer from inbreeding depression, especially in times of stress. Under natural conditions, organisms are exposed to more than one stressor at any one time, highlighting the importance of stress resistance traits. We studied how inbreeding- and immunity-related traits are correlated under different dietary conditions in the ant Formica exsecta. Its natural diet varies in the amount and nature of plant secondary compounds and the level of free radicals, all of which require detoxification to maintain organismal homeostasis. We found that inbreeding decreased general antibacterial activity under dietary stress, suggesting inbreeding-related …

Data from: Multiple aspects of plasticity in clutch size vary among populations of a globally distributed songbird

2014

1. Plasticity in life-history characteristics can influence many ecological and evolutionary phenomena, including how invading organisms cope with novel conditions in new locations or how environmental change affects organisms in native locations. Variation in reaction norm attributes is a critical element to understanding plasticity in life history, yet we know relatively little about the ways in which reaction norms vary within and among populations. 2. We amassed data on clutch size from marked females in eight populations of house sparrows (Passer domesticus) from North America and Europe. We exploited repeated measures of clutch size to assess both the extent of within-individual pheno…
