Mobility and transition of pedagogical expertise in Finland

2015

Mobility and transition of pedagogical expertise in Finland is a publication based on the project “Mobility among pedagogical experts”, which was funded by the European Social Fund. The project was carried out in 2010–2013 in collaboration with the Finnish Institute for Educational Research, Finnish National Board of Education and the Vocational Teacher Education College, Jyväskylä University of Applied Sciences. The publication gives an overall view of the teacher mobility and transition in the Finnish education system and discusses the key findings from the report on Mobility among pedagogical experts. Data for the above-mentioned project was collected by an online questionnaire (n = 4500…

Evidence for differential and redundant function of the Sox genes Dichaete and SoxN during CNS development in Drosophila.

2002

Group B Sox-domain proteins encompass a class of conserved DNA-binding proteins expressed from the earliest stages of metazoan CNS development. In all higher organisms studied to date, related Group B Sox proteins are co-expressed in the developing CNS; in vertebrates there are three (Sox1, Sox2 and Sox3) and in Drosophila there are two (SoxNeuro and Dichaete). It has been suggested there may be a degree of functional redundancy in Sox function during CNS development. We describe the CNS phenotype of a null mutation in the Drosophila SoxNeuro gene and provide the first direct evidence for both redundant and differential Sox function during CNS development in Drosophila. In the lateral neuro…

Functional characterization of the sea urchin sns chromatin insulator in erythroid cells.

2005

Abstract Chromatin insulators are regulatory elements that determine domains of genetic functions. We have previously described the characterization of a 265 bp insulator element, termed sns, localized at the 3′ end of the early histone H2A gene of the sea urchin Paracentrotus lividus. This sequence contains three cis-acting elements (Box A, Box B, and Box C + T) all needed for the enhancer-blocking activity in both sea urchin and human cells. The goal of this study was to further characterize the sea urchin sns insulator in the erythroid environment. We employed colony assays in human (K562) and mouse (MEL) erythroid cell lines. We tested the capability of sns to interfere with the communi…

PUBLIC TRANSPORT IN THE ERA OF AUTOMATISATION AND SHARING ECONOMY

2019

Background. Over half of the world's population lives in urbanized areas, cities emit over 75 % of global greenhouse gases [1]. One of the sources of pollution is transport. Therefore, striving for the development of sustainable transport systems in cities is crucial. Observing global trends in mobility allows noting the development of economy, automation and electrification of the automobile. These tendencies seem to have enormous potential to improve the functioning of transport systems and to maximize economic and environmental effects. Therefore, the aim of this article is to identify the benefits of using low-carbon autonomous vehicles, to spread the sharing mobility and to identify po…

A cross-country configurational approach to international academic mobility: exploring mobility effects on academics’ career progression in EU countr…

2022

This study takes a novel perspective on mobility as career script compliance to explore the factors that might influence how mobile academics in a country perceive the impact of international mobility on their overall academic career progression and job options. We conduct a country-level qualitative comparative analysis on a sample of 24 European Union (EU) countries, based on data from European Commission’s MORE3 indicator tool. We find that these perceptions about the impact are shaped by the dominant patterns of mobility in that country, and the general perception of academics in that particular country that international mobility is rewarded in the institutional promotion schemes. This…

Polymer solar cells based on diphenylmethanofullerenes with reduced sidechain length

2011

Diphenylmethanofullerenes (DPMs) show interesting properties as acceptors in polymer bulk heterojunction solar cells due to the high open circuit voltages they generate compared to their energy levels. Here we investigate the effect of reducing the alkane sidechain length of the DPMs from C12 to C6 in the properties of the solar cell. This change leads to an increase in the electron mobility, thus allowing for a lower fullerene content, which in turn results in an increase in the short circuit current and, finally, in an increase in the efficiency of the device (from 2.3 to 2.6%) due to the higher concentration of the more absorbing polymer in the film. Atomic force microscopy images and ex…

Naphthalenediimide Polymers with Finely Tuned In-Chain π-Conjugation: Electronic Structure, Film Microstructure, and Charge Transport Properties

2016

Naphthalenediimide-based random copolymers (PNDI-TVTx) with different π-conjugated dithienylvinylene (TVT) versus π-nonconjugated dithienylethane (TET) unit ratios (x = 100→0%) are investigated. The PNDI-TVTx-transistor electron/hole mobilities are affected differently, a result rationalized by molecular orbital topologies and energies, with hole mobility vanishing but electron mobility decreasing only by ≈2.5 times when going from x = 100% to 40%.

Growth and characterization of GdxHg1−xSe crystals

2008

Abstract The growth of GdxHg1−xSe crystals by the vertical Bridgman method was studied in the composition range 0⩽x⩽0.1. The structural and electronic properties of GdxHg1−xSe crystals were investigated as a function of composition. It was found that an increase in gadolinium content up to x=0.01 results in a decrease of structural defects and an increase in electron mobility up to the maximum value of μ77≈2.8×105 cm2/V s. Structural defects start to increase at x>0.01, and the formation of Gd2Se3 amorphous phase takes place at x>0.03. On the base of the electron-spin resonance investigation, it was shown that the Gd incorporates into the HgSe host in Gd3+ charge state at the concentration …

Electrospray ion mobility mass spectrometry of positively charged sodium bis[2-ethythexyl)sulfosuccinate aggregates.

2014

Collision cross-sections (CCS) of positively singly and multiply charged aggregates of the surfactant sodium bis(2-ethylhexyl)sulfosuccinate (AOTNa) in the gas phase have been measured by quadrupole ion mobility time-of-flight mass spectrometry. Calibration of the observed drift times to the CCS of the AOTNa non-covalent aggregates was achieved by collecting, under the same experimental conditions, the drift times of a range of singly and multiply charged polyalanine peptides whose CCS had been obtained by conventional ion mobility spectrometry. Together with an obvious increase of the aggregate cross-section with the aggregation number, it was found that the aggregate cross-section increa…
