The effects of book exposure and reading interest on oral language skills of children with and without a familial risk of dyslexia
2020
The potential role of home literacy environment (HLE) in children's language development has been widely studied. However, data on the HLE of children with familial risk (FR) of dyslexia are limited. In this longitudinal study, we examined (a) whether amount of book exposure and reading interest at age 4 were different in samples of Norwegian FR and no FR‐children, respectively, (b) whether these home literacy‐related factors exerted different effects depending on family‐risk status on vocabulary and grammar skills at school entry age (6 years) and (c) whether they contributed independently to language outcomes at age 6, after controlling for the 4;6‐year language skills. Results showed no …
Sociodemographic Correlates of Parental Co-Participation in Digital Media Use and Physical Play of Preschool-Age Children
2021
Young children’s digital media use and physical activity have gained attention in recent research. Parental co-participation has a major impact on children’s health consequences. This study addressed a gap in the research by investigating daily parental co-participation in children’s digital media use and physical play, using the family ecological model theoretical framework. The participants in this nationally representative cross-sectional study were 2512 Finnish parents with two- to six-year-old children. Parents completed a questionnaire. Sociodemographic correlates of co-participation and of the awareness of guidelines regarding co-participation and correlation between co-participation…
Rational Choice Theory and the Environment: Variants, Applications, and New Trends
2010
Rational choice theory (RCT) is a research paradigm based on methodological individualism. Collective phenomena are explained by assumptions about the behavior of (subjectively) rational individual or corporate actors. In environmental research, RCT is used to predict ecological perceptions, attitudes and behavior on the micro level, and to shed light on environmental outcomes on the macro level. The most fundamental insight from RCT is that environmental problems are often the result of a social dilemma, that is, individuals’ purposive action leads to unintended negative collective consequences. This chapter addresses variants of RCT including game theory, shows applications in the field o…

Positive gender congruency effects on shopper responses:Field evidence from a gender egalitarian culture
2021
National audience; This field study examined how customer-employee interactions are affected by the congruency between an employee's gender and the perceived gender image of the consumption context in one of the most gender equal cultures in the world (Scandinavia). Mystery shoppers had a service encounter with an employee across a set of physical commercial settings that were classified according to their gender image. The mystery shoppers noted the gender of the employee, provided employee evaluations, and indicated word-of-mouth (WOM) ratings. Shoppers who had a gender congruent service encounter (e.g., a female employee in a “feminine” consumption context) reported more favorable employ…
Atomic-force microscopy imaging of plasma membranes purified from spinach leaves
2000
Summary: Plasma membranes purified from spinach leaves by aqueous two-phase partitioning were examined by atomic-force microscopy (AFM) in phosphate buffer, and details on their structure were reported at nanometric scale. Examination of the fresh membrane preparation deposited on mica revealed a complex organization of the surface. It appeared composed of a first layer of material, about 8 nm in thickness, that practically covered all the mica surface and on which stand structures highly heterogeneous in shape and size. High-resolution imaging showed that the surface of the first layer appeared relatively smooth in some regions, whereas different characteristic features were observed in ot…
Decomposition of Microbial Necromass Is Divergent at the Individual Taxonomic Level in Soil
2021
The turnover of microbial biomass plays an important part in providing a significant source of carbon (C) to soil organic C. However, whether the decomposition of microbial necromass (non-living microbial biomass) in the soil varies at the individual taxa level remains largely unknown. To fill up these gaps, we compared the necromass decomposition of bacterial and archaeal taxa by separating live microbial biomass with 18O-stable isotope probing from dead microbial biomass in soil. Our results showed that most of the microbial necromass at the operational taxonomic unit level (88.51%), which mainly belong to Acidobacteria, Actinobacteria, Gemmatimonadetes, and Proteobacteria, decomposed sig…
Endocytosis in skeletal muscle fibers.
1999
Defining the organization of endocytic pathway in multinucleated skeletal myofibers is crucial to understand the routing of membrane proteins, such as receptors and glucose transporters, through this system. Here we analyzed the organization of the endocytic trafficking pathways in isolated rat myofibers. We found that sarcolemmal-coated pits and transferrin receptors were concentrated in the I band areas. Fluid phase markers were taken up into vesicles in the same areas along the whole length of the fibers and were then delivered into structures around and between the nuclei. These markers also accumulated beneath the neuromuscular and myotendinous junctions. The recycling compartment, lab…
Aidòs. Percorsi di etica del limite
2022
Come già Platone intuì con il mito di Protagora, la tecnica è figlia della finitezza. C’è tecnica, infatti, lì dove c’è bisogno di migliorare; ma lo stesso bisogno di migliorare è segno che non c’è ancora compimento. Nel crescente darsi da fare della tecnologia per strappare alla vita la sua imperfezione si nasconde così uno strano paradosso: lo scopo della tecnica non può che essere il proprio togliersi. Solo lì dove non ci sarà più tecnica, infatti, potrà esserci quella pienezza a cui l’uomo, tramite la tecnica, aspira. Ne consegue che il progresso qualitativo e quantitativo della tecnologia, lungi dall’avvicinarci gradualmente a un ultimo limite che sarà finalmente superato, è cifra di u…
