Path Following in Non-Visual Conditions.
2018
Path-following tasks have been investigated mostly under visual conditions, that is when subjects are able to see both the path and the tool, or limb, used for navigation. Moreover, only basic path shapes are usually adopted. In the present experiment, participants must rely exclusively on continuous, non-speech, and ecological auditory and vibrotactile cues to follow a path on a flat surface. Two different, asymmetric path shapes were tested. Participants navigated by moving their index finger over a surface sensing position and force. Results show that the different non-visual feedback modes did not affect the task's accuracy, yet they affected its speed, with vibrotactile feedback causin…
‘Ain't nothin' like the real thing’. Motivation and study processes on a work-based project course in information systems design
2007
Background. Advocates of the project method claim that project-based learning inspires student learning. However, it has been claimed that project-based learning environments demand quite a bit of self-regulation on the part of the learner. Aims. Consequently, it was tested whether students scoring low in self-regulation of learning experienced ‘friction’, an incompatibility between student self-regulation and the demands posed by the learning environment. This would be manifest in cognitive processing and motivation. Samples. The target group consisted of 58 mainly third-year Finnish university students taking a mandatory project course in information systems design. During the project cou…
Health science student teachers' perceptions of teacher competence: A qualitative study.
2019
Abstract Background Health science teacher competence is multifaceted and continuously changing according to national and international healthcare standards. Organizational restructuring and emphasis on cost effectiveness is changing the scope of health science teachers' practical work and their role in healthcare (worldwide). Aim This study aimed to describe student teachers' perceptions of the competencies needed to work as an educator in the healthcare field. Objective of study was to gain new knowledge which can be used in the development of teacher education programs in nursing science and to define a broader definition of the health science educators. Methods A qualitative study was c…
Nursing Education in Catalonia: Novice Professionals’ Appraisal of Its Quality and Usefulness. Does Mobility Play a Role?
2020
The present study aimed to examine the relationship between the quality of undergraduate education perceived by novice nurses and their retrospective satisfaction with their education. It also studied the relationships between the perceived usefulness of their education for their current jobs and the quality of the jobs held by novice nursing professionals. The moderator role of mobility in this relationship was also analyzed, as it reflects a boundary condition in which additional preparation or job opportunities may occur. The study used data from the graduates’ survey carried out by the Agència per a la Qualitat del Sistema Universitari de Catalunya (AQU) in 2017. The analysis of data fr…
High-Speed Imaging Analysis of Register Transitions in Classically and Jazz-Trained Male Voices
2014
<b><i>Background:</i></b> Little data are available concerning register functions in different styles of singing such as classically or jazz-trained voices. Differences between registers seem to be much more audible in jazz singing than classical singing, and so we hypothesized that classically trained singers exhibit a smoother register transition, stemming from more regular vocal fold oscillation patterns. <b><i>Methods:</i></b> High-speed digital imaging (HSDI) was used for 19 male singers (10 jazz-trained singers, 9 classically trained) who performed a glissando from modal to falsetto register across the register transition. Vocal fold osc…
Qualitative study of social and healthcare educators’ perceptions of their competence in education
2019
Competent educators are needed to ensure that social and healthcare professionals are effective and highly competent. However, there is too little evidence-based knowledge of current and required enhancements of educators' competences in this field. The aim of this study was to describe social and healthcare educators' perceptions of their competence in education. The study had a qualitative design, based on interviews with educators and rooted in critical realism. Forty-eight participants were recruited from seven universities of applied sciences and two vocational colleges in Finland, with the assistance of contact persons nominated by the institutions. The inclusion criterion for partici…
Temporal Structure of Human Gaze Dynamics Is Invariant During Free Viewing.
2015
We investigate the dynamic structure of human gaze and present an experimental study of the frequency components of the change in gaze position over time during free viewing of computer-generated fractal images. We show that changes in gaze position are scale-invariant in time with statistical properties that are characteristic of a random walk process. We quantify and track changes in the temporal structure using a well-defined scaling parameter called the Hurst exponent, H. We find H is robust regardless of the spatial complexity generated by the fractal images. In addition, we find the Hurst exponent is invariant across all participants, including those with distinct changes to higher or…
Continued Multidisciplinary Project-based Learning – Implementation in Health Informatics
2008
Summary Objectives: Problem- and project-based learning are approved methods to train students, graduates and post-graduates in scientific and other professional skills. The students are trained on realistic scenarios in a broader context. For students specializing in health informatics we introduced continued multidisciplinary project-based learning (CM-PBL) at a department of medical informatics. The training approach addresses both students of medicine and students of computer science. Methods: The students are full members of an ongoing research project and develop a project-related application or module, or explore or evaluate a sub-project. Two teachers guide and review the students’ …
Professional Qualification of German Physicians in Medical Informatics
1994
Abstract:In addition to the medical education in the Federal Republic of Germany which includes a compulsory Medical Informatics course there exists a formal program for professional qualification of physicians in Medical Informatics. After two years of clinical practice and 1.5 years of professional training at an authorized institution, a physician may receive in addition to the medical degree a “supplement Medical Informatics”. The qualification requirements are described in detail. Physicians with the additional Medical Informatics qualification perform responsible tasks in their medical domain and serve as partners for fully specialized Medical Informatics ex-’ perts in the solution of…
Evaluation of aging behavior under salt-fog spray conditions of green sandwich structures
2018
In this paper, the aging resistance of sandwich structures made with cork agglomerate as core and flax-reinforced polymeric laminates as face sheets was investigated for the first time. In order to evaluate their durability in a hostile environment, a sandwich plate was manufactured by vacuum bagging technique and aged under salt-fog spray conditions, according to ASTM B 117 standard. The evolution of the sandwich mechanical properties during the aging exposition was analyzed by carrying out quasi-static flexural tests and Charpy impact tests both on unaged specimens and on specimens aged for 10, 25, and 60 days, respectively. The quasi-static experimental results showed that despite the sa…
