Use of Bacillus thuringiensis toxins for control of the cotton pest earias insulana (Boisd.) (Lepidoptera: Noctuidae)
2006
ABSTRACT Thirteen of the most common lepidopteran-specific Cry proteins of Bacillus thuringiensis have been tested for their efficacy against newly hatched larvae of two populations of the spiny bollworm, Earias insulana . At a concentration of 100 μg of toxin per milliliter of artificial diet, six Cry toxins (Cry1Ca, Cry1Ea, Cry1Fa, Cry1Ja, Cry2Aa, and Cry2Ab) were not toxic at all. Cry1Aa, Cry1Ja, and Cry2Aa did not cause mortality but caused significant inhibition of growth. The other Cry toxins (Cry1Ab, Cry1Ac, Cry1Ba, Cry1Da, Cry1Ia, and Cry9Ca) were toxic to E. insulana larvae. The 50% lethal concentration values of these toxins ranged from 0.39 to 21.13 μg/ml (for Cry9Ca and Cry1Ia, …
Primary culture of avian embryonic heart forming region cells to study the regulation of vertebrate early heart morphogenesis by vitamin A
2014
Background: Important knowledge about the role of vitamin A in vertebrate heart development has been obtained using the vitamin A-deficient avian in ovo model which enables the in vivo examination of very early stages of vertebrate heart morphogenesis. These studies have revealed the critical role of the vitamin A-active form, retinoic acid (RA) in the regulation of several developmental genes, including the important growth regulatory factor, transforming growth factor-beta2 (TGFβ2), involved in early events of heart morphogenesis. However, this in ovo model is not readily available for elucidating details of molecular mechanisms determining RA activity, thus limiting further examination o…
Adaptation and implementation of the German social-emotional learning programme Papilio in Finland : A pilot study
2019
This study investigated the cross‐national adaptation and implementation of Papilio, a German social–emotional learning programme, in Finnish early childhood education and care (ECEC) centres. Papilio is a developmentally focused, scientifically based intervention programme focused on preventing behavioural problems and fostering social–emotional competence in children aged 3–7. The aim of this study was to investigate and evaluate the cross‐national adaptation and cross‐cultural adaptation and implementation of Papilio in the Finnish ECEC context. Results from qualitative interviews with one Finnish Papilio trainer, 11 early childhood education (ECE) teachers, two ECE special education tea…
Rationalising public support for private early childhood education and care: the case of Finland
2019
In Finland, early childhood education and care (ECEC) is traditionally publicly provided. However, private ECEC provision has increased during the past decade, largely as a result of financial support from the public sector. Drawing on qualitative interviews with municipal decision-makers, this article identifies three frames within which publicly subsidised private ECEC provision and marketisation are rationalised: the pragmatic frame, the government frame and the choice frame. The results show that even though market logics and tendencies seem to have gained a strong foothold in local policies, there is a keen interest in universalism and maintaining public control over local ECEC provisi…
The involvement of autistic children in early childhood education
2023
Research on the involvement of autistic children in daily activities in inclusive early childhood education is scarce. In Finland, all children, including autistic children, under the age of seven (before basic education) are entitled to participate in early childhood education and care. Children also attend compulsory, free-of-charge pre-primary education during the year before their basic education begins. Furthermore, attending early childhood education and care is not dependent whether a child requires day care because of their parents’ work. Autistic children attend early childhood education in inclusive day care centres. Thus, in this study, we examined the involvement of autistic chi…
Entre théorie et pratique en ecdotique galloromane
2015
Ce chapitre traite du conditionnement réciproque entre théorie et pratique éditoriales en philologie galloromane (ancien français et ancien provençal) dans une perspective historique, depuis l’introduction de la méthode dite lachmannienne jusqu’à nos jours. On a essayé d’illustrer, d’une part, comment l’expérience éditoriale des philologues ait influencé leur propositions de méthode, et, d’autre part, comment une application trop rigide ou bien peu contrôlée de ces méthodes ait parfois produit des éditions critiques insatisfaisantes sous certains aspects, ou bien elle ait causé des défaillances au niveau de la reconstruction textuelle. À travers la leçon des maîtres de différentes écoles ph…
Differences in parasite community composition support ecological differentiation in a freshwater gadoid fish
2022
Several northern freshwater fishes have gone through rapid adaptive radiation after the last glacial period, resulting in new species or intraspecific morphs with distinct life histories. Parasite infections can promote adaptive radiations and spatiotemporal differences in patterns of infections can potentially reveal incipient or ongoing speciation processes. We investigated intraspecific differentiation in a freshwater gadoid fish, burbot (Lota lota), by exploring differences in parasite infections between two potential life-history morphs in Lake Konnevesi, Central-Finland, one reproducing species characteristically in shallow littoral waters in February and the other possibly in deep pr…
The nature of self-employment: how does gender matter?
2010
This paper analyses female and male entrepreneurship and the differences between them in Finland. The female self-employment rate is clearly lower than that of male self-employment in Finland. The paper shows that differing behaviour accounts for differing rates of self-employment between females and males. The predicted earnings differential between self-employment and paid employment has a divergent effect on the probabilities of self-employment. For males, it is positive (as expected). For females, it has no effect, which accentuates the other motives they have for self-employment. Both spouse and family are found to have bigger effects on female self-employment than on male self-employm…
Il dovere di riservatezza dei dipendenti delle organizzazioni internazionali
2021
Apesar das diferenças estruturais e regulatórias que caracterizam as organizações internacionais individuais, a doutrina de hoje é unânime em afirmar a capacidade de cada organização de criar seu próprio sistema jurídico interno. A relação de trabalho dentro dessas organizações reproduz claramente muitas das características da relação de trabalho internas a um Estado e, embora haja uma falta de regras internacionais uniformes sobre o emprego, e cada organização internacional tenha absoluta autonomia jurídica e administrativa, é possível identificar certas obrigações e direitos dos funcionários internacionais que se replicam, de forma ampla e homogênea, na maioria das organizações. O artigo …
More skilled, better paid : labour-market returns to postsecondary vocational education
2017
Outside the USA, relatively little is known about the labour-market returns to postsecondary vocational (or polytechnic) education. Yet, polytechnics in Europe are distinct from US community colleges. This paper focuses on the labour-market returns to polytechnic attendance in Finland, where polytechnics are representative of many European countries. Using matching methods and longitudinal administrative data, we find that, compared to individuals with no postsecondary education, students who attend polytechnics have higher annual earnings of €3,300 to €3,700 and employment gains of 2.5 to 6.6 percentage points 10 years after the entry decision. However, the returns vary by personal charact…
