Abstract in German Web-basierte Trainings werfen viele Fragen auf bezüglich des zu erwartenden Nutzungsverhaltens von Kursteilnehmenden. Bisher liegen nur wenige Studien mit wenigen Aussagen darüber vor, wie Web-basierte Trainings im Rahmen berufsbegleitender Weiterbildungsmaßnahmen genutzt werden. Auf Basis einer Analyse des Nutzungsverhaltens von Studenten des Studienganges WINFOLine macht der v

The socio-technical design of a library and information science collaboratory

The aim of this research is to design a collaboratory that is a socio-technical platform to support sharing research data collection instruments in a social science discipline, in particular library and information science. A socio-technical approach to design that includes a literature review, an empirical study and use cases, are used to create specifications for a collaboratory prototype. Futur

Fire Design of Wooden Structures

The paper describes and discusses the state of the art concerning the possibilities of an analytical prediction of the real fire behaviour of wooden structures and structural members. The principles of a probability based design are outlined with reference to a physical model according to Fig. 2, connected to a natxral compartment fire exposure. The design procedure is exemplified by a Swedish met

Time Domain Characterization of Circular Polarization Selective Structures

This paper investigates how typical frequency domain concepts such as circular polarization and axial ratio can be given a useful meaning in the time domain. The relationship between the linear polarizations of a circularly polarized time dependent signal is shown to be the Hilbert transform, and the instantaneous axial ratio can be computed from envelope functions, obtained from corresponding ana

Can we tell what we said when we hear ourselves saying something else? - Real-time speech manipulation as a new instrument for the testing of verbal intentions and self monitoring

It is commonly assumed that speech production is initiated and guided by clear pre-verbal intentions. These intentions are moreover supposed to function as a standard of accuracy against which actual performance can be measured. Alternative positions to such a centrally governed process have been offered, but very few empirical attempts have been made to explore the issue. We aimed to remedy this

Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

Popular Abstract in Swedish Mörkerseendet är en mycket känslig nervfunktion och mycket känsligare för låg syrgastillförsel än högre mentala funktioner. Mörkerseendet är kraftigt reducerat hos patienter med två kliniskt sett så olika tillstånd som förträngd halspulsåder (carotisstenos) och "trögflytande blod" (polycytämi). Gemensamt för båda patientgrupperna är en under lång tid störd blodcirculatiPurpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans. Methods: Repeated automatic dark adaptometry was recorded monocularly in 21 c

Experimental characterisation of shear and compaction band mechanisms in porous sandstone by a combination of AE and 3D-DIC

Shear and compaction bands represent two fundamental failure modes in sandstones. The identification of these features in both the natural outcrops and the laboratory scale yields useful insights into the mechanisms of localised deformation. Several conventional and advanced experimental full-field methods have been developed in order to shed light into the processes involved, as well as qualify a

Epidemiological dental indices and self-perceived oral health in adolescents: ecological aspects

The aim of this study was to investigate the correlations between epidemiological indices (objective) and self-perceived oral health (subjective) in adolescents at school level, and to study gender differences in epidemiological indices and in self-perceived oral health. The study comprised two sets of data from Skaraborg County, Sweden: 1. Self-reported questionnaires answered by adolescents at a
