<p><strong>SEM study of species of <em>Oswaldella</em> Stechow, 1919 (Cnidaria, Hydrozoa, </strong><br /><stro…
2015
Oswaldella is the most speciose genus, and one of the most characteristic, of hydrozoans inhabiting the Antarctic benthic marine ecosystem. Its species have relatively many important taxonomic characters allowing for their identification. Some of them, however, are difficult to study properly with a compound microscope. With the aim of improving scientific knowledge concerning species of the genus, a SEM survey of species of Oswaldella was carried out to study key morphological characters. Fourteen out of the 27 known nominal species were considered. The study has revealed unknown important characters, such as the presence of nematothecae associated with the nematophores at the cauline apop…
Coordinating collaborative writing in an online environment
2018
This study investigated how university students (n = 28) coordinated their collaborative online writing and what kinds of coordination profiles were found among the students. Further, the study examined the quality of the essays produced by groups of students varying in their combinations of coordination profiles. Students’ written comments on their writing processes (n = 583) were divided into episodes focusing on coordination. Eight different categories of collaborative activities during online collaboration were found. The students’ joint essays (n = 9) were evaluated as high, moderate and low according to the number of topics, key concepts, and integration of Internet sources in the ess…
University Students´ Knowledge Construction during Face to Face Collaborative Writing
2014
Collaborative writing combines social processes of writing with cognitive knowledge construction processes, and thus may lead to deeper learning than individual working. This study examined students’ knowledge construction during face-to-face collaborative writing. University students (n = 21) prepared themselves for the collaborative task by reading about developmental theories in a course book and writing individual summaries of them. In small groups, the students discussed each others’ summaries and wrote a joint essay on one of the theories. The data comprise the students’ individual summaries (n = 21), the students’ discussions during the essay writing (8177 speech turns), and the stud…
Therapeutic metaphors and personal meanings in group poetry therapy for people with schizophrenia
2021
This article concerns the therapeutic potential of metaphor in group poetry therapy, concentrating on the poetry therapy process of people diagnosed with schizophrenia. The data was collected in a one-year poetry therapy group. The main questions were: (1) What kind of therapeutic potential can metaphors offer in group poetry therapy? (2) What are the personal meanings and evaluations that the participants give to the therapy process and its effects on their lives? (3) What are the most significant elements in poetry therapy from the viewpoint of the client? The analysis was based on the Grounded theory method. The results showed that the most significant therapeutic factors of the process …
Kirkman's tetrahedron and the fifteen schoolgirl problem
2011
We give a visual construction of two solutions to Kirkman's fifteen schoolgirl problem by combining the fifteen simplicial elements of a tetrahedron. Furthermore, we show that the two solutions are nonisomorphic by introducing a new combinatorial algorithm. It turns out that the two solutions are precisely the two nonisomorphic arrangements of the 35 projective lines of PG(3,2) into seven classes of five mutually skew lines. Finally, we show that the two solutions are interchanged by the canonical duality of the projective space.
Efficient formulation of a two-noded geometrically exact curved beam element
2021
The article extends the formulation of a 2D geometrically exact beam element proposed by Jirasek et al. (2021) to curved elastic beams. This formulation is based on equilibrium equations in their integrated form, combined with the kinematic relations and sectional equations that link the internal forces to sectional deformation variables. The resulting first-order differential equations are approximated by the finite difference scheme and the boundary value problem is converted to an initial value problem using the shooting method. The article develops the theoretical framework based on the Navier-Bernoulli hypothesis, with a possible extension to shear-flexible beams. Numerical procedures …
Spelling in Finnish : the case of the double consonant
2021
Because of its regularity, it is relatively easy to learn to read and spell in Finnish. However, a specific hurdle in spelling acquisition seems to be the doubling of consonant letters. In this study on consonant letter doubling spelling in Finnish children (91 Grade 1 and 191 Grade 2 children), we asked two questions. First, are items with double consonant letters (e.g., “kissa” [ˈkisːɑ] ‘cat’) indeed harder to spell than single consonant items (e.g., “kisa” [ˈkisɑ] ‘contest’)? Second, is consonant doubling harder for stop consonants (e.g., “takki” [ˈtɑkːi] ‘coat’) than for continuant consonants (e.g., “kissa&rdq…
Variable exponent p(x)-Kirchhoff type problem with convection
2022
Abstract We study a nonlinear p ( x ) -Kirchhoff type problem with Dirichlet boundary condition, in the case of a reaction term depending also on the gradient (convection). Using a topological approach based on the Galerkin method, we discuss the existence of two notions of solutions: strong generalized solution and weak solution. Strengthening the bound on the Kirchhoff type term (positivity condition), we establish existence of weak solution, this time using the theory of operators of monotone type.
The case of literacy motivation : Playful 3D immersive learning environments and problem-focused education for blended digital storytelling
2018
The University of Patras' Library Services designed and offered to primary and secondary schools the pilot educational program “From the Ancient to the Modern Tablets”, featuring immersive multimedia learning experiences about the book history. The pilot program consisted of three stages: a playful library tour, followed by an interactive game-based digital storytelling activity with game elements, and a collaborative creative reflective hands-on activity. Utilizing the avatar psychology power, the visualization and simulation affordances of 3D immersive learning environments and the appeal of storytelling and game-based learning, the “gamified” blended narrative on the book evolution enabl…
Scripting as a pedagogical method to guide collaborative writing : university students' reflections
2020
A collaboration script is a set of instructions used to improve collaborative learning among students in technology-enhanced environments. Previously, university students’ perspective has been under-represented in the study on collaboration scripts. In this article, we focus on understanding students’ experiences in a scripted collaborative writing task, especially from the perspective of following the script. The study was conducted among undergraduate students (N = 91) taking a master-level educational science course at one university each in Finland and Belgium. Divided into 25 groups, each with three to five members, the students worked on collaborative writing tasks. During their share…
