Understanding the influence of context in technology integration from teacher educators’ perspective
2021
The perspective of teachers is important for advancing the use of technology in classrooms. A considerable number of research studies have explained context in ways that have narrowed the understanding of its impact on successful technology integration. This study employs the Technological Pedagogical and Content Knowledge (TPACK) model as a lens in understanding factors influencing teachers’ integration of technology in classrooms. Data were collected using focused interviews of 19 teacher educators of three colleges of education from the southern part of Nigeria. The results reveal that among the level contexts, the meso level presented the most challenges to teachers’ efforts at integrat…
Guidance Provided by Teacher and Simulation for Inquiry-Based Learning: a Case Study
2016
Current research indicates that inquiry-based learning should be guided in order to achieve optimal learning outcomes. The need for guidance is even greater when simulations are used because of their high information content and the difficulty of extracting information from them. Previous research on guidance for learning with simulations has concentrated on guidance provided by the simulation. Little research has been done on the role of the teacher in guiding learners with inquiry-based activities using simulations. This descriptive study focuses on guidance provided during small group investigations; pre-service teachers (n = 8) guided third and fifth graders using a particular simulatio…
The CDIO Syllabus 3.0 - An Updated Statement of Goals
2022
The CDIO Initiative is going through a process of reconsidering and updating the CDIO approach for engineering education development. Previous work resulted in substantial updates of the twelve CDIO standards and the introduction of “optional” CDIO standards. This paper reports on a similar review and update of the CDIO Syllabus to version 3.0. It has been developed by a working group consisting of four sub-groups and iterated and refined guided by feedback from the whole CDIO community. There are mainly three external drivers that 18 Proceedings of the 18th International CDIO Conference, hosted by Reykjavik University, Reykjavik Iceland, June 13-15, 2022. motivate the changes: sustainabili…
Parvovirus induced alterations in nuclear architecture and dynamics.
2009
The nucleus of interphase eukaryotic cell is a highly compartmentalized structure containing the three-dimensional network of chromatin and numerous proteinaceous subcompartments. DNA viruses induce profound changes in the intranuclear structures of their host cells. We are applying a combination of confocal imaging including photobleaching microscopy and computational methods to analyze the modifications of nuclear architecture and dynamics in parvovirus infected cells. Upon canine parvovirus infection, expansion of the viral replication compartment is accompanied by chromatin marginalization to the vicinity of the nuclear membrane. Dextran microinjection and fluorescence recovery after ph…
Seasonal gene expression kinetics between diapause phases in Drosophila virilis group species and overwintering differences between diapausing and no…
2015
AbstractMost northern insect species experience a period of developmental arrest, diapause, which enables them to survive over the winter and postpone reproduction until favorable conditions. We studied the timing of reproductive diapause and its long-term effects on the cold tolerance of Drosophila montana, D. littoralis and D. ezoana females in seasonally varying environmental conditions. At the same time we traced expression levels of 219 genes in D. montana using a custom-made microarray. We show that the seasonal switch to reproductive diapause occurs over a short time period and that overwintering in reproductive diapause has long-lasting effects on cold tolerance. Some genes, such as…
Dielectric breakdown strength of epoxy bimodal-polymer-brush-grafted core functionalized silica nanocomposites
2014
The central goal of dielectric nanocomposite design is to create a large interfacial area between the matrix polymer and nanofillers and to use it to tailor the properties of the composite. The interface can create sites for trapping electrons leading to increased dielectric breakdown strength (DBS). Nanoparticles with a bimodal population of covalently anchored molecules were created using ligand engineering. Electrically active short molecules (oligothiophene or ferrocene) and matrix compatible long poly(glycidyl methacrylate) (PGMA) chains comprise the bimodal brush. The dielectric breakdown strength was evaluated from recessed samples and dielectric spectroscopy was used to study the di…
Is Complexity of Daily Activity Associated with Physical Function and Life Space Mobility among Older Adults?
2022
Purpose Information about mobility, and physical function may be encoded in the complexity of daily activity pattern. Therefore, daily activity pattern complexity metrics could provide novel insight regarding the relationship between daily activity behaviour and health. The purpose of the present study was to examine the association between the complexity of daily activity behaviour, and mobility and physical function among community-dwelling older adults aged 75, 80, and 85 years-of-age. Methods A total of 309 participants wore accelerometers concurrently on the thigh and the trunk for at least 3 consecutive days. Five activity states (lying, sitting, standing, walking, or activity other t…
Immateriaalioikeuksien hallinta pilvipalveluissa teknologian ja pilvipalveluiden ominaispiirteiden näkökulmasta
2016
Pilvipalvelut tarjoavat yksityisille kuluttajille ja organisaatioille mahdollisuuden kasvattaa tehokkuutta. Vaikka pilvipalvelut tarjoavat etuja, on niihin liittyviä omistus- ja immateriaalioikeuksia käsitelty alan kirjallisuudessa joko vähän tai niitä on käsitelty muun tietoturvan ohella. Tässä tutkielmassa pyritään löytämään niitä pilvipalveluille ominaisia piirteitä, jotka vaikuttavat immateriaali- ja omistusoikeuksien määräytymiseen kirjallisuuskatsauksen avulla ja vastaamaan mitä pilvipalvelun potentiaalisen asiakkaan tulisi tehdä pitääkseen nämä omistus- ja immateriaalioikeudet itsellään. Tutkielman tuloksia ovat kirjallisuuskatsauksen avulla tehty pilvipalveluiden ominaispiirteiden j…
Pohjoismainen työmarkkinamalli digipaniikin aikakaudella
2017
Työn tulevaisuudesta käytävissä keskusteluissa muutosta pidetään vääjäämättö mänä ja deterministisenä erityisesti silloin, kun on kyse teknologian vaikutuksesta työhön ja työllisyyteen. Kuitenkin vertailevat tutkimukset osoittavat, että työ markkinoiden rakennemuutoksen polarisaatiokehitys eli jakautuminen ”hyviin” ja ”huonoihin” töihin on ollut Pohjoismaissa muuta Eurooppaa lievempää. Teknologiseen determinismiin liittyvä vääjäämättömyyden retoriikka epäpolitisoi muutoksen. Teknologian kehitystä, käyttöönottoa ja seurauksia on pyritty poliittisesti hallitsemaan. Pohjoismaisen työmarkkinamallin rakentuminen on tästä mainio esimerkki. Työn tulevaisuutta koskevissa keskusteluissa tulisikin …
Technology management, networking positions and work/life boundaries among working adult students
2021
In this digitalised world, crossing boundaries between life domains is becoming increasingly easy. We are constantly faced with the need to define whether we are online or offline, and technology management is now an integral part of daily life. Technology management, which is affected by the individual's networking position, has different components: connectivity management, online self-presentation and privacy management. The objective of this study is to explore technology management strategies among working adult students. The study identifies three networking positions: socio-affective enthusiasts, context-contingent pragmatists and pragmatic avoiders. These three groups have specific …
