Patterns of action transitions in online collaborative problem solving : A network analysis approach
2022
AbstractIn today’s digital society, computer-supported collaborative learning (CSCL) and collaborative problem solving (CPS) have received increasing attention. CPS studies have often emphasized outcomes such as skill levels of CPS, whereas the action transitions in the paths to solve the problems related to these outcomes have been scarcely studied. The patterns within action transitions are able to capture the mutual influence of actions conducted by pairs and demonstrate the productivity of students’ CPS. The purpose of the study presented in this paper is to examine Finnish sixth graders’ (N = 166) patterns of action transitions during CPS in a computer-based assessment environment in w…
Liiketoimintaverkostoon vaikuttavat tekijät - teknologinen näkökulma
2013
Tutkielmassa tutkitaan liiketoimintaverkostoja ja siihen vaikuttavia tekijöitä, erityisesti teknologian näkökannalta. Liiketoimintaverkostolla tarkoitetaan verkostoa jossa toimii useampi yritys ja joita sitoo toisiinsa erilaiset suhteet. Teknologialla tarkoitetaan tutkielmassa kaikkea teknologiaa jota käytetään muun muassa informaation eri muotojen luomiseen, tallennukseen, kommunikointiin ja käyttöön. Tarkemmin on tarkasteltu internettiä ja sitä hyödyntäviä teknologioita kuten sähköpostia, videoneuvottelua ja erilaisia IOS-järjestelmiä sekä digitalisaatiota. Tutkielman tutkimuskysymyksiä tarkasteltiin liiketoimintaverkoston kolmen myytin ja kolmen paradoksin teorioiden kautta. Tutkimuksen …
Value Co-creation for Smart Villages: The Institutionalization of Regional Service Ecosystems
2020
Building a versatile portfolio of public and private digital-enabled services is vital in rural and sparsely populated regions, where traditional market mechanisms alone cannot guarantee the availability of essential services. However, contemporary services tend to build on prevalent institutions, often governed by decisions based on market mechanisms, such as economies of scale – service-by-service and village-by-village. A shift is suggested towards networks of smart villages co-creating value as regional service ecosystems. We draw from institutional theory and employ the Service-dominant logic (SDL) framework in investigating value co-creation in rural villages in Sweden. Analyzing 53 l…
Stability of social support during school transitions: Associations with truancy and not completing upper secondary education in normative time
2022
Not completing upper secondary education is often presignaled by truancy from school. Student-perceived social support from family, peers, and teachers can prevent truancy and the risk of not completing education. However, prior studies have not focused on the stability of social support across school transitions. This longitudinal study of 1901 Finnish students examined the extent to which social support was stable or specific to primary, lower secondary, and upper secondary schools. Moreover, we examined whether support was associated with not completing upper secondary education in normative time and whether truancy mediated the relationship between support and not completing education. …
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…
Performance analysis of Latvian zenith camera
2018
Since finalizing of design in 2016, the digital zenith camera of the University of Latvia was involved in a number of test observations as well as field observations at about 70 different sites. The paper presents analysis of observation results, estimation of instrument’s performance and accuracy. Random and systematic error sources are outlined. Impact of anomalous refraction on vertical deflection determination is discussed. Results of adaptation of GAIA reference star catalog for astrometric data reduction are reported.
Structure and dynamics in liquid bismuth and Bin clusters: A density functional study
2014
Density functional/molecular dynamics simulations with more than 500 atoms have been performed on liquid bismuth at 573, 773, 923, and 1023 K and on neutral Bi clusters with up to 14 atoms. There are similar structural patterns (coordination numbers, bond angles, and ring patterns) in the liquid and the clusters, with significant differences from the rhombohedral crystalline form. We study the details of the structure (structure factor, pair, and cavity distribution functions) and dynamical properties (vibration frequencies, diffusion constants, power spectra), and compare with experimental results where available. While the three short covalent bonds typical to pnictogens are characteristi…
Transcriptomic analysis of host-pathogen relationship in Vibrio vulnificus
2020
Vibrio vulnificus es un patógeno bacteriano que habita en ecosistemas costeros de salinidades intermedias localizados en zonas del planeta templadas y cálidas. Esta especie es una de las más sensibles al calentamiento global habiendo experimentado una expansión en su distribución geográfica hacia zonas costeras de aguas frías como las que rodean países tan próximos al círculo polar como como Noruega y Groenlandia, de las que se aísla en las épocas cálidas del año. En su medio natural la bacteria puede encontrarse en un estado metabólico inactivo, conocido como estado VBNC (viable but not culturable) que es inducido en circunstancias ambientales adversas (temperaturas por debajo de 10ºC, sal…
