Macroalgae production in Northern Europe: Business and government perspectives on how to regulate a novel blue bioeconomy
2022
Macroalgae biomass production, understood as cultivation and harvesting, is a minor industry in Europe at present, but the sector is recognized as having substantial growth potential. Here, we framed the environmental license as a boundary object between business and authorities and investigated the details of macroalgal licensing procedures in seven Northern European countries (Finland, Estonia, Sweden, Germany, Norway, Iceland, and Scotland). We conducted surveys and interviews with macroalgae companies and licensing authorities to understand the challenges faced by both sides. Generally, macroalgae production in Northern European countries is regulated by environmental and water laws and…
Acquisition of Mathematical and Linguistic Skills in Children With Learning Difficulties
2021
Comorbid learning difficulties in linguistic and mathematical skills often emerge in primary school age. The cause of coinciding of both learning difficulties during children’s development spanning pre- and primary-school age is not yet well understood. To address this research gap, we used data from the German National Educational Panel Study (NEPS; n = 301) of four groups of children which were categorized according to their skill levels in pre-school age: children with learning difficulties isolated in linguistic skills (LD), children with learning difficulties isolated in mathematical skills (MD), children with learning difficulties combined in linguistic and mathematical skills (MD/LD)…
Mathematics Skills of Kosovar Primary School Children: A Special View on Children with Mathematical Learning Difficulties
2018
The present study examined the development of mathematics skills of Kosovar primary school children in terms of their gender, living area, socio-economic status, and achievement level. A special emphasis was placed on longitudinal investigations of the development of mathemat-ics skills in children with learning difficulties in mathematics over a 2-year and 4-month period. Participants were 553 fourth-graders, 85 of whom identified with mathematical learning difficulties were classified into two subgroups: children with low mathematics achievement and children with limited mathematics ability. Results have shown that there were no gender differences in mathematics achievement. Children’s li…
Influence of cultivation techniques and use of two nutritive solution with different electrical conductivity on the production and quality of cucumbe…
2009
The most suitable techniques and use of F1 hybrids enable greenhouse production to achieve high yields, with crops all year round. In Sicily, greenhouse production of cucumber is for fresh use (slicers), producing large fruit. The cultivation technique most suited to greenhouses is the vertical single stem. However, an innovative technique being proposed is of cultivation on a trellis, eliminating lower branches, and training the remaining branches upwards (vertical shoot positioning, VSP). Cucumbers in the south of Italy are grown as the main crop or as a catch crop between 2 main crops. The crop should be rotated on the same soil only after 3-4 years with another crop, unless the land is …
Special Education Teachers’ Identification of Students’ Reading Difficulties in Grade 6
2020
his study investigated special educational needs (SEN) teachers’ (n = 29) assessment practices and the accuracy of their ratings of the students’ (M age = 12.75 years, n = 55) skill levels in reading fluency and reading comprehension. Teachers rated their sixth grade students’ fluency and comprehension on a three-point scale, and the students were also tested in group tests. Results showed that SEN teachers used several assessment practices simultaneously but mostly relied on observations. The correlations between the teacher ratings and the test scores were significant but moderate in fluency and weak in comprehension. Only two thirds of low-performing students having difficulties in fluen…
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…
GraphoGame – a catalyst for multi-level promotion of literacy in diverse contexts
2015
GraphoGame (GG) is originally a technology-based intervention method for supporting children with reading difficulties. It is now known that children who face problems in reading acquisition have difficulties in learning to differentiate and manipulate speech sounds and consequently, in connecting these sounds to corresponding letters. GG was developed to provide intensive training in matching speech sounds and larger units of speech to their written counterparts. GG has been shown to benefit children with reading difficulties and the game is now available for all Finnish school children for literacy support. Presently millions of children in Africa fail to learn to read despite years of pr…
What is individual in individualised instruction? Five storylines of meeting individual needs at school
2015
Abstract The purpose of this narrative case study was to examine the meanings and practices of individualised instruction narrated by two seventh-grade Finnish pupils with mild learning difficulties, their mothers, their special education teacher and researchers. The data comprise narrative interviews and field notes. The analysis showed that the narrators had various, even conflicting, experiences of individualisation, which was narrated through five storylines: individual needs as difficulties and limitations; individualisation as the ideal principle for inclusive education; individualisation as a bureaucratic procedure; individualised instruction as making room for emotions, and individu…
The role of stress in the onset of depressive disorders
2002
Background: We conducted the present study to evaluate the impact of stressful events on the onset of depressive disorders in a Spanish clinical sample, compared to a control group matched for age, sex, civil status and social class. We compared our results with those of other studies carried out with samples that were both clinically and culturally similar to ours. Method: Fifty depressed patients that were diagnosed with a depressive episode in the 6 months prior to the interview and 50 healthy controls were included in the study. Both groups were compared on the “Life Events and Difficulties Schedule” (LEDS). Results: Of the depressive patients, 68 % compared to only 18 % of the control …
Inhibition of growth of measles virus by mycoplasma in cell-cultures and the restoring effect of arginine
1970
Presence of mycoplasma in MK cell cultures caused an inhibition of measles virus, as revealed by a lower plating efficiency. When arginine is supplemented to the cell-system, mycoplasma contaminated cells yield plaque titers as high as those of uncontaminated cells. The essential role of arginine for plaque formation of measles virus is suggested also by experiments in which arginine added to the agar overlay restored the plating efficiency of measles virus in cultures maintained in a minimal nutrient medium.
