Modal and Structural FEM Analysis of a 50 ft Pleasure Yacht
2012
In this paper a structural Finite Element analysis of a 50 ft pleasure vessel is presented. The study is performed under different loads conditions: modal analyses have been done in order to find the natural frequencies of the vessel, structural analyses to verify the strength of the vessel to design loads. The design loads for the vessel considered are computed according to RINA rules for the construction and classification of pleasure vessels [1]. Two different composites are used for the lamination: one is a monolithic sequence of short fibre and balanced glass lamina, used for the bottom of the vessel and for structural reinforcements, the other is a sandwich made of glass fibre composi…
Insights into the agency, positioning and development of professional Finnish language skills of international nursing students
2016
This article focuses on international students studying in an English-mediated nursing degree program in Finland. From sociocognitive and ecological perspectives, this study examines the development of the students’ professional Finnish language skills and agency during their practical training. In addition, this article explores how students are positioned as capable workers. To shed light on the students’ professional language skills, agency, and positionings, interviews with vocational teachers, head nurses, and two international nursing students are examined using narrative analysis. The findings suggest that due to their lack of Finnish language skills, international students are posit…

Licensing policies for a new product
2005
This paper studies licensing policies for the owner of a new product and addresses their welfare impact in the assessment of market failures. We show that the best licensing policy for the patent holder is fixed fee licensing with an exclusive territory clause. Consumers are also better off with fixed fees but do not prefer the exclusive territory clause. Social welfare is higher under exclusive territories when fixed costs are not too large. As for efficiency, the number of licences in the private market equilibrium falls short of the socially optimal solution. Our analysis discloses that (i) any policy measures aimed at enhancing the diffusion of technology, in terms of the number of lice…
Video sharing application for educational use: Usability and impacts of participation modes
2014
For the past few years, the use of video lectures in universities has been on the increase. Production of video lectures will bring flexibility that is needed for study and enable the utilization of pedagogical solutions based on new videos. On the other hand, applications for the sharing and use of lecture videos clearly designed for educational requirements are not available. This article introduces an application for the sharing and use of videos. The application was designed and implemented for educational purposes, and it has been in use already for two years. The article examines, with the help of a SUS survey, students' and lecturer's satisfaction with the application and its usabili…
Search forBs0→μ+μ−andB0→μ+μ−Decays with CDF II
2011
A search has been performed for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -} decays using 7 fb{sup -1} of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. The observed number of B{sup 0} candidates is consistent with background-only expectations and yields an upper limit on the branching fraction of {Beta}(B{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 6.0 x 10{sup -9} at 95% confidence level. We observe an excess of B{sub s}{sup 0} candidates. The probability that the background processes alone could produce such an excess or larger is 0.27%. The probability that the combination of background and the expe…
Dialogue through the eyes: Exploring teachers’ focus of attention during educational dialogue
2020
Abstract This study explored teachers’ focus of attention during educational dialogue. Teachers’ focus of attention was recorded in 54 Grade 1 classrooms using Tobii Pro Glasses 2 mobile eye-tracking device. From the video recordings, episodes of educational dialogue were identified and categorised by quality. Teacher’s focus of attention on students was examined during the dialogue episodes. Results showed that teachers allocated their attention relatively unevenly among the students. More students got visual attention during high-quality educational dialogue than during moderate-quality dialogue. This study provides insight into the quality of educational dialogue by combining assessment …
On Human–Computer Interaction in Brain–Computer Interfaces
2014
In this chapter, theoretical reflections on human–computer interaction in brain–computer interfaces (BCIs) are combined with the results of an empirical investigation concerning non-invasive EEG-based BCI users’ experiences with this technology. After a short overview of transhumanist visions in the field of neurotechnology this text discusses some anthropological positions concerning interaction between man and technical devices. The focus will be on the concept of “transparency”. Then some empirical results of a pilot study which investigated BCI users’ experiences concerning human–computer interaction in BCI use are presented and discussed against the anthropological background.
Interim Report on Survey of Teaching Practices In Developing Countries
2013
This paper illustrates a research method appropriate for researchers examining teaching practices and teacher training in poor countries. The method of research described here does not compare with large scale studies in terms of sample size, scientific rigor, and sophisticated statistical analysis. We believe, however, that it can, provide valid information sufficient in accuracy for policy making. Most importantly, we believe, this method offers a feasible way for national researchers to explore why teachers teach as they do in their country. A fundamental assumption is that once in the classroom most teachers learn little more about teaching. In the absence of any systematic feedback or …

This case study examined teachers’ on-the-fly formative assessment conversations, that is, how teachers collect information from students’ thinking and use that information to support their learnin...
