    Abstract Information and communication technology (ICT) has made higher education available to many students in a new way. The role of online learning in higher education institutions (HEIs) has grown to an unprecedented scale due to the COVID-19 pandemic. The diversity of higher education students has increased, and accessible solutions are needed. New European and national regulations support these trends. The research reported in this paper was conducted in Finland, which is one of the leading European countries in terms of high technology and digitalisation. The aim of this research is to explore the accessibility of all Finnish HEIs' (

    Abstract Trust-based e-assessment systems are increasingly important in the digital age for both academic institutions and students, including students with special educational needs and disabilities (SEND). Recent literature indicates a growing number of studies about e-authentication and authorship verification for quality assurance with more flexible modes of assessment. Yet understanding the acceptability of e-authentication systems among SEND students is underexplored. This study examines SEND students' views about the use of e-authentication systems, including perceived advantages and disadvantages of new technology-enhanced assessment. This study aims to shed light on this area by examining the attitudes of 267 SEND students who used, or were aware of, an authentication system known as adaptive trust-based e-assessment system for learning (TeSLA). The results suggest a broadly positive acceptability of these e-authentication technologies by SEND students. In the view of these students, the key advantages are the ability of proving the originality of their work, and trust-based e-assessment results; the key disadvantages are the possibility that the technology might not work or present wrong outputs in terms of cheating.

    Abstract The cryopreservation of dormant buds can be a feasible method for preserving germplasm of cold-tolerant woody plants. In the present study, we evaluated the effects of pre-desiccation, thawing method, and the rehydration of bud sections on the post-cryopreservation recovery of dormant blackcurrant buds in vitro. The estimated recovery of small- and medium-sized buds was 80.1 and 62.7% respectively for desiccated buds and 67.8 and 72.3% respectively for non-desiccated buds. The pre-desiccation of bud sections enhanced the number of the shoots regenerated from vegetative buds (2.3 vs. 4.7). The estimated recovery of fast-thawed buds was better after 14-day than after 7-day rehydration (85 vs. 59%). In slowly thawed buds the difference between 14-day and 7-day rehydration was not significant (73 vs. 62%). The estimated recovery of vegetative and flower buds was 77.7 and 41.1% respectively after 7-day rehydration, and 95.2 and 43.6% respectively after a 14-day rehydration period. The rehydration of bud sections was not necessary for the in vitro recovery of non-desiccated, fast-thawed buds. Of the 23 blackcurrant cultivars cryopreserved using non-desiccated dormant buds collected from a greenhouse, the estimated recovery of 22 cultivars ranged between 42 and 90%.

    Abstract The aim of plant gene banks is to preserve genetic resources selected based on their phenotypic, agronomic, historical or other cultural values for future utilization. In the present study the modified PVS2 droplet vitrification technique was tested and optimized for cryopreservation of a large diversity of blackcurrant (R. nigrum L.) accessions propagated in vitro and selected into a national gene bank core collection. Out of four accessions tested to optimize the method, three recovered and regenerated by 89–97% on average, but one recalcitrant in vitro line only by 25%. The tested post-cryopreservation recovery media with different macronutrient and growth regulator levels showed no generalized effect on regenerated shoots, but the effect of recovery media was different between cultivars. When the whole regeneration chain from cryopreservation via micropropagation to greenhouse conditions was tested, shoots at least 1 cm in length were found necessary for successful transfer ex vitro. The long-term cryopreservation of 22 blackcurrant accessions was finally conducted, with practices slightly modified from the tested protocol. The estimated recovery of shoot tips after 9 weeks in vitro was 17–94% with at least 75% recovery in seven accessions and at least 40% recovery in 19 out of 22 accessions. Only one accession had no cryopreservation success. The results demonstrated that the modified droplet vitrification technique is appropriate for a large diversity of blackcurrant accessions. However, cultivar-related differences and recovery procedures are to be considered for success in regeneration and ex vitro adaptation.

    Abstract Background: At present there exists no overview of the range of evidence currently available regarding the effectiveness of occupational health interventions (OHI).
    Methods: Articles published in 2000 and 2001 in 16 general and specialized biomedical journals were searched for evaluations of OHI studies.
    Results: Out of 8,687 articles searched there were 148 OHI studies. In 21% of the studies the study design was a randomized controlled trial, in 28% it was a controlled trial, an interrupted time-series in 7% and a different design in 44%. The occupational health outcome was exposure in 27% of the studies, worker behavior in 12%, disease symptoms in 30%, disability or sickness absence in 24%, injuries in 4%, and quality of care in 3%.
    Conclusions: High quality evaluation studies are conducted in all areas of occupational health. However, it is clear that more are needed and the methodology used could be improved.
