Biology of the sauropod dinosaurs: the evolution of gigantism
2010
The herbivorous sauropod dinosaurs of the Jurassic and Cretaceous periods were the largest terrestrial animals ever, surpassing the largest herbivorous mammals by an order of magnitude in body mass. Several evolutionary lineages among Sauropoda produced giants with body masses in excess of 50 metric tonnes by conservative estimates. With body mass increase driven by the selective advantages of large body size, animal lineages will increase in body size until they reach the limit determined by the interplay of bauplan, biology, and resource availability. There is no evidence, however, that resource availability and global physicochemical parameters were different enough in the Mesozoic to ha…
Long-Term COVID: Case Report and Methodological Proposals for Return to Work
2022
Almost two years after the beginning of the SARS-CoV-2 pandemic, the knowledge of which in the infectious and therapeutic spheres is constantly evolving, attention paid to the medicolegal aspects linked to this emergency phenomenon has mainly focused on the liability implications falling on healthcare personnel. With regard to the medicolegal assessment of the outcomes of COVID-19 illness, although it is a procedure that is commonly used, and although references in the assessment tables in force have been adhered to, a specific assessment protocol has not been standardized that takes into account, from an objective point of view, the degree of severity of the long-term residual outcomes and…
Dopamine Related Genes Differentially Affect Declarative Long-Term Memory in Healthy Humans
2020
In humans, monetary reward can promote behavioral performance including response times, accuracy, and subsequent recognition memory. Recent studies have shown that the dopaminergic system plays an essential role here, but the link to interindividual differences remains unclear. To further investigate this issue, we focused on previously described polymorphisms of genes affecting dopaminergic neurotransmission: DAT1 40 base pair (bp), DAT1 30 bp, DRD4 48 bp, and cannabinoid receptor type 1 (CNR1). Specifically, 669 healthy humans participated in a delayed recognition memory paradigm on two consecutive days. On the first day, male vs. female faces served as cues predicting an immediate moneta…
Unveiling the Mysteries of Dyslexia-Lessons Learned from the Prospective Jyväskylä Longitudinal Study of Dyslexia.
2021
This paper reviews the observations of the Jyväskylä Longitudinal Study of Dyslexia (JLD). The JLD is a prospective family risk study in which the development of children with familial risk for dyslexia (N = 108) due to parental dyslexia and controls without dyslexia risk (N = 92) were followed from birth to adulthood. The JLD revealed that the likelihood of at-risk children performing poorly in reading and spelling tasks was fourfold compared to the controls. Auditory insensitivity of newborns observed during the first week of life using brain event-related potentials (ERPs) was shown to be the first precursor of dyslexia. ERPs measured at six months of age related to phoneme length identi…

The longitudinal development of employee well-being: a systematic review
2016
This article reports a systematic review of findings on the long-term development of employee well-being, taking into account the effects of time lag, age, and job change. High-quality quantitative empirical studies focusing on employee affective well-being based on the circumplex model and utilizing measurements at more than two points in time were searched from eight databases. The systematic analysis of the 40 studies revealed that the level of employee well-being was generally high but not fixed – instead changes in mean levels over time were typical. In addition, the stability of well-being was found to be relatively low, as the explained variances were below 50%. Age and change of job…
Social Competence and Moderate to Vigorous Physical Activity of School-Aged Children through a Creative Physical Education Intervention
2019
Traditional school physical education focuses on physical skills or strategies with an expectation that learning these skills lead to healthier lifestyle outside physical education classes, while children’s overall moderate to vigorous physical activity (MVPA) is widely decreasing. Creative Physical Education (CPE) understands physical education more holistically, as the central pedagogical element of movement is social learning. The current study examined the development of social competence in school physical education (PE) and total moderate to vigorous physical activity (MVPA) participation through a CPE-based intervention. Participants were 363 (177 intervention, 186 control) children …
The energy and identification continua of burnout and work engagement : Developmental profiles over eight years
2017
Abstract Understanding of the mutual developmental dynamics between burnout and work engagement is limited due to the lack of longitudinal studies with long follow-ups and multi-wave data. This study sought to identify subgroups of employees characterized by long-term exhaustion-vigor (energy continuum) and cynicism-dedication (identification continuum). A further important aim was to investigate differences between the identified subgroups in their experiences of progress in their personal work goals. Five-wave, eight-year follow-up data among Finnish white-collar professionals ( n = 168) were studied using Latent Profile Analysis (LPA). The analysis yielded three exhaustion-vigor subgrou…
Literacy Skill Development of Children With Familial Risk for Dyslexia Through Grades 2, 3, and 8
2015
This study followed the development of reading speed, reading accuracy, and spelling in transparent Finnish orthography in children through Grades 2, 3, and 8. We compared 2 groups of children with familial risk for dyslexia—1 group with dyslexia (Dys_FR, n = 35) and 1 group without (NoDys_FR, n = 66) in Grade 2—with a group of children without familial risk for dyslexia (controls, n = 72). The Dys_FR group showed persistent deficiency, especially in reading speed, and, to a minor extent, in reading and spelling accuracy. The Dys_FR children, contrary to the other 2 groups, relied heavily on letter-by-letter decoding in Grades 2 and 3. In children not fulfilling the criteria for dyslexia in…
Online Research and Comprehension Performance Profiles Among Sixth-Grade Students, Including Those with Reading Difficulties and/or Attention and Exe…
2022
This study identified online research and comprehension (ORC) performance profiles of 436 sixth-grade students (206 girls) aged 12–13 years. We included learner groups with different learning-related difficulties and explored how students’ reading habits were represented in various performance profiles. First, students’ ORC performance was examined with a validated web-based assessment measuring their skills in locating, evaluating, synthesizing, and communicating information. Second, reading fluency and teacher-rated attention and executive function (EF) difficulty scores were used to form learner groups: (1) students with reading difficulties, (2) students with attention and EF difficulti…
