Aging and longevity: An evolutionary approach
2021
Abstract In the chapter, first of all, the definition of aging, longevity, and the various types of aging are discussed. Then, analyzing various theories of aging, it is recalled how evolution teaches us that there should be no genes selected to promote aging. Aging is not planned but derives from the accumulation of physical damage, due to limited investments in maintenance and repair as well as from the epigenetic changes. After sufficient time has passed, the increasing levels of these defects interfere with the performance of tissues and organs, resulting in a breakdown of self-organizing system and a reduced ability to adapt to the environment.
Models of Immune Aging
2018
Abstract Biochemical changes, impaired immune responses to new antigens, and inflammation-based disorders are commonly found in aged individuals. Thus, many studies have addressed the immune system of healthy elderly, including centenarians, since a well-preserved immune system appears to be a major factor of longevity. Longitudinal studies in humans are complicated, as most immune changes associated with aging develop slowly. Human models of accelerated immune aging in clinical conditions allow exploring the age-related changes in the human immune system and the mechanisms of accelerated aging in chronic infections and autoimmunity. Even if they do not perfectly mimic immune function and i…
The relationships between school belonging and students’ motivational, social-emotional, behavioural, and academic outcomes in secondary education: a…
2019
This meta-analytic review examines the relationships between students' sense of school belonging and students' motivational, social-emotional, behavioural, and academic functioning in secondary education. Moreover, it examines to what extent these relationships differ between different student groups (grade level, SES), measurement instruments, and region. The meta-analysis included 82 correlational studies, published in peer-reviewed journals between 2000 and 2018. Results revealed, on average, a small positive correlation with academic achievement, and small to moderate positive correlations with motivational outcomes such as mastery goal orientations; with social-emotional outcomes such …
Home Literacy Activities and Children’s Reading Skills, Independent Reading, and Interest in Literacy Activities From Kindergarten to Grade 2
2020
According to the Home Literacy Model (Sénéchal and LeFevre, 2002, 2014), young children can be exposed to two distinct types of literacy activities at home. First, meaning-related literacy activities are those where print is present but is not the focus of the parent–child interaction, for example, when parents read storybooks to their children. In contrast, code-related literacy activities focus on the print, for example, activities such as when parents teach their children the names and sounds of letters or to read words. The present study was conducted to expand the Home Literacy Model by examining its relation with children’s engagement in literacy activities at home and at school as Fi…
Comorbid Fluency Difficulties in Reading and Math: Longitudinal Stability Across Early Grades
2018
We examined the prevalence of comorbidity of dysfluent reading and math skills longitudinally in a representative sample ( N = 1,928) and the stability of comorbid and single difficulties from first to fourth grades. The findings indicated that half the children who showed very low performance in one skill also evidenced low or very low performance in the other. Comorbid difficulties had somewhat higher prevalence in third and fourth graders than in first and second graders. The stability of comorbid difficulties was found to be established from Grade 2 onward, but the stability of single difficulties increased steadily across grades. Overall, the findings emphasize the relatively strong s…
Care Poverty Within the Home Space: Exploring the Emotional Experiences of Unmet Care Needs
2021
Older adults face inequalities in care. The concept of care poverty has been developed to point out how unmet care needs are not just an individual issue but a phenomenon linked to social and economic disadvantage and societal inequality. In this paper, we approach the question of care poverty by focusing on its intertwinement with emotions and the home space. We analyze how the presence, or more commonly absence, of care shapes interviewees’ descriptions of emotional experiences tied to the home space. Our data consists of 12 semi-structured interviews conducted in 2019 and 2020 with customers of outreach work for older adults in Finland. These customers typically face a situation that can…
Longitudinal Associations of First-grade Teaching with Reading in Early Primary School
2019
The present study examined the longitudinal associations between first-grade teaching practices and children's reading skills development from Grade 1 to Grade 3. Using the Early Childhood Classroom Observation Measure (ECCOM), the teaching practices of 32 Finnish teachers were observed in Grade 1. Students' (N = 359) word recognition and sentence reading skills were assessed yearly from Grade 1 to Grade 3. The person-oriented analysis identified three profiles of teaching practices in Grade 1: child-centred teaching style, teacher-directed teaching style, and a mixed child-centred and teacher-directed teaching style. Furthermore, the results showed that children whose Grade 1 teachers used…
Standardised functional assessment in long-term care for older people: perspective of Finnish care workers
2021
Objective measures and documentation are increasingly used in the care for older people to promote efficiency and productivity. A standardised assessment of functional capacity is one such measure. In this study, we examined the meanings given to standardised functional assessment by care workers who provide long-term care for older people. Gathered from eight Finnish long-term care facilities, the data consisted of one-on-one interviews with practical and registered nurses (n = 24). In the data analysis, we employed the discursive approach. We identified three discourses in the care workers’ talks that differed in the meaning given to standardised functional assessment in the process of ca…
Vocational teachers’ pathways in the course of a curriculum reform
2011
Teachers face continuous changes, many of which significantly influence their professional identities and work practices. This study investigates Finnish vocational teachers’ pathways in the course of a curriculum reform. The data were obtained by interviewing 14 vocational teachers twice, i.e. at the initial and later stages of the reform. This study used a narrative approach to analyse the interviews as whole and also to illustrate variations between teachers. The teachers were found to exhibit distinctive pathways through the reform: an empowerment pathway, a critical but adaptive pathway, an open and expectant pathway, a successful transformation pathway, and a struggling pathway. The p…
Data from: Demographic responses of a site-faithful and territorial predator to its fluctuating prey: long-tailed skuas and arctic lemmings
2013
1. Environmental variability, through interannual variation in food availability or climatic variables, is usually detrimental to population growth. It can even select for constancy in key life-history traits, though some exceptions are known. Changes in the level of environmental variability are therefore important to predict population growth or life-history evolution. Recently, several cyclic vole and lemming populations have shown large dynamical changes, that might affect rodent predator demography or life histories. 2. Skuas constitute an important case study among rodent predators, because of their strongly saturating breeding productivity (they lay only two eggs) and high degree of …
