Central Region Upgrade for the Jyväskylä K130 Cyclotron
2020
The Jyväskylä K130 cyclotron has been in operation for more than 25 years providing beams from H to Au with energies ranging from 1 to 80 MeV/u for nuclear physics research and applications. At the typical energies around 5 MeV/u used for the nuclear physics program the injection voltage used is about 10 kV. The low voltage limits the beam intensity especially from the 18 GHz ECRIS HIISI. To increase the beam intensities the central region of the K130 cyclotron is being upgraded by increasing the injection voltage by a factor of 2. The new central region with spiral inflectors for harmonics 1-3 has been designed. The new central region shows better transmission in simulations than the origi…
The Simpson paradox of school grading in Italy
2009
Abstract Data from the 2003 OECD-PISA Survey for Italy reveal a striking difference in the relationship between students’ competence (as measured by PISA score in Mathematics) and school grades across regions: a competence level granting bare sufficiency in the North yields excellence grades in the South. This has spurred a lively debate on education policy in the country, based on the inference drawn from this evidence that grading practices are excessively different in the two areas. We show in this note that this inference overlooks a Simpson paradox hidden in the data. After a more careful analysis, the above inference is seen to be wrong. The crucial omitted variable is the school-leve…
The role of individual processes and learning environment in the prediction of grades in a sample of Norwegian students
2018
Student grades are traditionally used to evaluate academic achievement in higher education. A review of previous research indicates a relatively clear tendency to adopt either an individual or contextual approach in exploring this subject. The present study represents an attempt to simultaneously examine effects of individual variables and learning environment on academic achievements as measured in grades. The study adopts a quantitative approach and reports data collected from students enrolled in early childhood education in a mid-sized university in Norway. Results of a stepwise hierarchical regression demonstrate that individual variables (e.g. nonmandatory school attendance, self-effi…
Cross-lagged relations between math-related interest, performance goals and skills in groups of children with different general abilities
2015
Abstract This study examined the longitudinal relations among math-related interest, performance goals, and math skills in different ability groups. The participants were 790 Estonian children who were assessed at Grade 2 and Grade 3. The results of SEM analysis showed that previous math skills predicted positively math interest and negatively performance-avoidance goals at Grade 3. Also, Grade 2 performance-avoidance goals were negatively related to subsequent interest towards math. Comparing low-ability students with other students indicated that Grade 3 interest was positively predicted by previous skills, and negatively by performance-approach and -avoidance goals specifically in low-ab…
Rapid malignant progression of an intraparenchymal choroid plexus papillomas
2018
Background: Choroid plexus tumors (CPTs) are rare neoplasms accounting for only 0.3-0.6% of all brain tumors in adults and 2-5% in children. The World Health Organization (WHO) classification describes three histological grades: grade I is choroid plexus papilloma (CPP), grade II is atypical papilloma, and grade III is the malignant form of carcinoma. In adults, CPTs rarely have a supratentorial localization. Case Description: Here we report a very rare case of an intraparenchymal parietal CPP with a rapid histological transition from grade I to grade III WHO in a 67-year-old man, in <7 months. Conclusion: Because of the rarity of these oncotypes, descriptions of each new case are useful…
Lett å få 5, nesten umulig å få 6 : En kvalitativ studie av videregående elevers opplevelser med vurdering i kroppsøving
2019
Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 Background:There is little research knowledge on how students experience being evaluated in physical education. I however find this to be an engaging subjectfor both teachers and students. Therefore, based on this, I wish to investigatethis subject further. Purpose:The purpose of this study is to investigatehow high school students experience being evaluated in physical education. Thesis statement:“How do high school students experience being evaluated?” Method:Two schools from Vest-Agder have helpedshed light on this issue through qualitative semi structured research group interviews.Analytical terminologydeveloped by Pierre…
Polish Adolescents’ Perceptions of English and Their Desire to Learn It
2016
In the process of foreign language learning the way in which students perceive the language may have a strong facilitative impact on their language acquisition process, especially when this perception is positive (Despagne, 2010). Unfortunately, it has not yet been clearly established whether the relationship between perceptions and foreign language achievement can be explained by the moderating power of the student’s desire to learn the foreign language. For the purpose of this paper it is hypothesized that the learner’s perception of the foreign language is strongly related to the desire to learn it, leading to higher achievement in cases of positive perception. In order to corroborate th…
Perceived teacher support and language anxiety in Polish secondary school EFL learners
2011
The teacher’s role is vital, both in respect to achieving academic goals, and with regard to the regulation of emotional and social processes. Positive perceptions of teacher support can endorse psychological wellness, and help maintain students’ academic interests, higher academic achievement and more positive peer relationships. The teacher who shows understanding, empathy and consistency in their behavior helps students start forming an identity, which will assist them in coping with stress and anxiety directly connected with the foreign language learning process (language anxiety). The main aim of this research is to investigate the relationship between teacher support and language anxi…
School grading and institutional contexts
2011
We study how the relationship between students' cognitive ability and their school grades depends on institutional contexts. In a simple abstract model, we show that unless competence standards are set at above-school level or the variation of competence across schools is low, students' competence valuation will be heterogeneous, with weaker schools inflating grades or flattening their dependence on competence, therefore reducing the information content and comparability of school grades. Using data from the OECD-PISA 2003 Survey, the model is applied to a sample of four countries, namely Australia, Germany, Italy, and the Netherlands. We find that in Australia, schools' heterogeneity does …
A New Species of the Genus Crenubiotus (Tardigrada: Eutardigrada: Adorybiotidae) from Salt Spring Island, Strait of Georgia, British Columbia (Canada)
2022
Currently, the recently erected genus Crenubiotus (Adorybiotidae, Macrobiotoidea) includes only three species, all of which are characterised by dentate lunulae and cuticular tubercules organised in the band in the dorso-caudal part of the body. By means of integrative taxonomy, we describe a fourth species of the genus: Crenubiotus salishani sp. nov., from Salt Spring Island in British Columbia, Canada. The new species has been found in the moss growing on rock and differs from the other species in the genus due to the presence of a median anterior mucrone in the third band of the oral cavity armature (OCA) and by the presence of evident thickenings on the eggshell connecting the neighbour…
