What causes the large extensions of red-supergiant atmospheres? Comparisons of interferometric observations with 1-D hydrostatic, 3-D convection, and…
2015
We present the atmospheric structure and the fundamental parameters of three red supergiants, increasing the sample of RSGs observed by near-infrared spectro-interferometry. Additionally, we test possible mechanisms that may explain the large observed atmospheric extensions of RSGs. We carried out spectro-interferometric observations of 3 RSGs in the near-infrared K-band with the VLTI/AMBER instrument at medium spectral resolution. To comprehend the extended atmospheres, we compared our observational results to predictions by available hydrostatic PHOENIX, available 3-D convection, and new 1-D self-excited pulsation models of RSGs. Our near-infrared flux spectra are well reproduced by the P…
Traditional studying for examination versus constructivist learning tasks: Do learning outcomes differ?
1998
ABSTRACT Students' learning outcomes on an educational psychology course which involved studying three textbooks were compared between a constructivist class without a final examination and a traditional class concluding with an examination. The constructivist group (n = 16) studied the coursebooks with the help of writing assignments, discussed their assignments in groups and wrote an essay. The control group (n = 23) read the books on their own, attended lectures and took an examination. Learning outcomes were investigated (1) as the students' subjective learning experiences; (2) as changes in the students' learning conceptions; and (3) as measured by a traditional examination in which th…
Teaching and learning business ethics in a multicultural group
2017
Building on a constructivist learning theory and a case teaching method, this article suggests a mixed learning approach for teaching business ethics in a multicultural group. The purpose is to present the objectives and implementation of the mixed learning approach in a case course with a multicultural group. Based on the students' feedback, we also analyse and discuss the effects of the mixed learning approach on students' learning experiences. The article contributes to the growing stream of literature on business ethics teaching in higher education by presenting an approach that allows teachers and students to join in constructive knowledge creation in a multicultural group. In so doing…
Theoretical and pedagogical perspectives on orchestrating creativity and collaborative learning
2011
The role of teacher is increasingly related to designing and arranging collaborative learning situations in which fruitful and creative group work may occur. This thematic review presents recent studies on creativity and collaborative learning from the perspective of the teacher as conductor of learning processes. The precondition for the design and orchestration of these kinds of learning situations is analysing and understanding of creative and collaborative processes and their contextual adaption. Thus, the first section of this review focuses on the theoretical vantage points of creativity and collaborative learning mainly from socio-cultural perspective. Based on this theoretical groun…
Blogging as a research and educational tool: a three years experience
2008
Abstract Blogging can be also used to share knowledge in research and education. We have been using many blogs with the following purposes. One goal has been to raise awareness about research methods in the information technology field by supporting information exchange, collaboration, and cooperation between researchers. We have been using a common blog for 3 years to share inter- and intra disciplinary knowledge among us. We have also collected stories and interviewed colleagues and friends. An other goal is the use of blogs during our teaching experience as an instrument to support the exchange of knowledge with students. A comparison of the use of blogging is presented with positive and…
Robust coordinated control algorithm for multiple marine vessels with external disturbances
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/597195 Open Access The problem of coordinated control for multiple marine vessels in the presence of external disturbances is considered in this paper. A robust coordinated control algorithm is proposed for multiple marine vessels. The proposed robust coordinated control algorithm is divided into two parts. The first part develops an extended state observer to estimate the disturbances of marine vessels. The second part presents a robust coordinated control algorithm based on the output of the extended state observer. Furthermore, the rob…
Teacher coping profiles in relation to teacher well-being : a mixed method approach
2021
The aim was to investigate teachers’ coping profiles and their relations to teacher well-being. Questionnaire data was collected from 107 Finnish teachers. Theory-driven content analysis of teachers’ responses revealed three coping categories: problem-focused, emotion-focused and mixed problem- and emotion-focused. Next, teachers were categorized into four coping profiles by using latent profile analysis: Low-coping users (21%), Problem-focused-coping users (15%), High-coping users (12%) and Emotion-focused-coping users (52%). Low-coping-user teachers reported less stress and fewer depressive symptoms and sleep problems compared to Emotion-focused-coping users. Using a compact amount of cop…
“Art as a Way to Life”: Bereavement and the Healing Power of Arts and Writing
2003
Reading, writing, music, and fine arts are widely acknowledged to have therapeutic value to those bereaved. Narratives of coping with the help of arts are commonly told. Yet, the experiences of bereavement and the healing powers of arts and writing are rarely discussed and analyzed in social sciences. In this article, I search for a way to study the therapeutic power of arts and writing on a personal level. Using empathy as a metaphorical tool, I read an unpublished autobiography about a mother's grief and coping process through my own experiences of bereavement. I strive for emotional verisimilitude and apply a poetic form when citing the autobiography to highlight the evocative tone of t…
Italian multicenter, prospective study to evaluate the negative predictive value of 16- and 64-slice MDCT imaging in patients scheduled for coronary …
2009
This was a prospective, multicenter study designed to evaluate the utility of MDCT in the diagnosis of coronary artery disease (CAD) in patients scheduled for elective coronary angiography (CA) using different MDCT systems from different manufacturers. Twenty national sites prospectively enrolled 367 patients between July 2004 and June 2006. Computed tomography (CT) was performed using a standardized/optimized scan protocol for each type of MDCT system (> or =16 slices) and compared with quantitative CA performed within 2 weeks of MDCT. A total of 284 patients (81%) were studied by 16-slice MDCT systems, while 66 patients (19%) by 64-slice MDCT scanners. The primary analysis was on-site/off…
Integrated Simulation and Formal Verification of a Simple Autonomous Vehicle
2018
This paper presents a proof-of-concept application of an approach to system development based on the integration of formal verification and co-simulation. A simple autonomous vehicle has the task of reaching an assigned straight path and then follow it, and it can be controlled by varying its turning speed. The correctness of the proposed control law has been formalized and verified by interactive theorem proving with the Prototype Verification System. Concurrently, the system has been co-simulated using the Prototype Verification System and the MathWorks Simulink tool: The vehicle kinematics have been simulated in Simulink, whereas the controller has been modeled in the logic language of t…
