Does ICT Usage Erode Routine Occupations at the Firm Level?
2019
We present decompositions and regression analyses that evaluate the routinization hypothesis and occupational polarization at the firm level. We establish two important facts. First, the results for the increasing abstract and declining routine occupation shares of total wage bill are consistent with the routinization hypothesis at the firm level. Second, the observed changes coincide with the usage of ICT in firms. This implies that disappearing middle-level (routine) work can be traced to firm-level technological change. Peer reviewed
Vocational teachers’ pathways in the course of a curriculum reform
2011
Teachers face continuous changes, many of which significantly influence their professional identities and work practices. This study investigates Finnish vocational teachers’ pathways in the course of a curriculum reform. The data were obtained by interviewing 14 vocational teachers twice, i.e. at the initial and later stages of the reform. This study used a narrative approach to analyse the interviews as whole and also to illustrate variations between teachers. The teachers were found to exhibit distinctive pathways through the reform: an empowerment pathway, a critical but adaptive pathway, an open and expectant pathway, a successful transformation pathway, and a struggling pathway. The p…

Yläkoulun oppilaiden ja opettajien käsityksiä uusmedian hyödyntämisestä opetuksessa
2011
Tutkimuksessa selvitetään yhdeksäsluokkalaisten oppilaiden sekä yläkoulun äidinkielen ja kirjallisuuden opettajien käsityksiä uusmedioista, niiden käytöstä nuorten vapaa-ajalla ja koulussa sekä niiden pedagogisista mahdollisuuksista opetuksessa. Aineistona on viisi oppilashaastattelua sekä viisi opettajahaastattelua. Aineisto analysoitiin ensin sisällönanalyysin keinoin ja sen jälkeen analyysia syvennettiin diskurssianalyysillä. Tutkimuksessa selvisi, että uusmediat ovat opettajien vapaa-ajalla niin kutsutussa hyötykäytössä: he etsivät internetistä tietoa tai hyödyntävät sitä tuntien suunnittelussa. Haastatellut oppilaat sen sijaan käyttävät internetiä lähinnä ajanvietteen takia, mikä tosin…
Breathing woodwinds : music therapy for asthma and COPD rehabilitation
2014
Filhan(2010) arvion mukaan hengityssairaudet koskettavat vuosittain miljoonaa suomalaista. Tutkimus tarjoaa vaihtoehdon potilaan omaa vastuuta korostavaan kuntoutukseen. Astmaryhmälle, kaksi lasta ja aikuinen, sekä keuhkoahtaumapotilaalle annettiin 12 viikkoa puhallinsoittimiin painottuvaa musiikkiterapiaa. Hengitysharjoituksia ja puhallinsoittimien soittoa käytettiin hengityselinten vahvistamiseksi musiikin tuodessa harjoitteluun motivaatiota. Voiko puhallinsoittimia painottava musiikkiterapia normaalihoitoon lisättynä vaikuttaa myönteisesti hengityssairauksista kärsivän elämänlaatuun? Kahdentoista viikon tuloksissa kvalitatiivinen materiaali antoi tuloksia. PEF lukemat pysyivät samoina, m…
Data from: There is no general model for occlusal kinematics in conodonts
2015
Knowledge of conodont element function is based largely on analysis of morphologically similar P1 elements of few comparatively closely related species known from abundant articulated remains. From these, a stereotypical pattern of rotational occlusion has been inferred, leading to the suggestion that this may represent a general model for ozarkodinin P1 elements at the very least. We test the generality of this occlusal model through functional analysis of Pseudofurnishius murcianus P1 elements which, though superficially similar to homologous elements in gnathodids, evolved their platform morphology independently, through a different mode of morphogenesis, and in a different topological p…
19F-MRI of perflubron for measurement of oxygen partial pressure in porcine lungs during partial liquid ventilation
2001
A method for in vivo measurement of oxygen partial pressure (pO2) in porcine lungs during partial liquid ventilation (PLV) with perflubron (PFOB) was developed. A pulse sequence for high-resolution MRI of the distribution of PFOB in the lung after intratracheal administration was developed as well. Moreover, quantitative measurements of longitudinal relaxation time T(1) of (19)F resonances for assessment of regional pO2 are described. Due to the need to acquire data during a single expiratory breathhold, only low SNRs were achieved in vivo. Therefore, simulations were performed to investigate the influence of background noise on T(1) values calculated from data with low SNR. Based on these …
Suppression of phase ambiguity in digital holography by using partial coherence or specimen rotation
2008
In this paper we present two approaches for extracting the surface profile as well as obtaining 3D imaging of near field objects by usage of partial coherence and digital holography. In the first approach a light source with given temporal partial coherence is used to illuminate a near field object. The reflected light is interfered with the reference source. By computing the local contrast of the generated fringes one may estimate the 3D topography and the profile of the object. This approach extracts the 3D information from a single image, and its accuracy does not depend on triangulation angle like in fringe projection methods. The second approach is tomography based. There we illuminate…
GPCALMA: An Italian mammographic database of digitized images for research
2006
In this work the implementation of a database of digitized mammograms is described. The digitized images were collected since 1999 by a community of physicists in collaboration with radiologists in several Italian hospitals, as a first step in order to develop and implement a Computer Aided Detection (CAD) system. 3369 mammograms were collected from 967 patients; they were classified according to the type and the morphology of the lesions, the type of the breast tissue and the type of pathologies. A dedicated Graphical User Interface was developed for mammography visualization and processing, in order to support the medical diagnosis directly on a high-resolution screen. The database has be…
Image Processors for Digital Angiography Algorithms and Architectures
1986
After a period of experimental and clinical development,(1–9) digital processing of angiographic X-ray video image sequences is now routinely applied in clinical and research work. The clinical advantages offered by this approach have been discussed in several reports.(10–12) The primary application is the improved visualization of regions of the heart and circulation opacified by X-ray contrast material during angiographic and angiocardiographic examinations. More complex techniques are being developed for improved functional analysis based on digitized angiograms. Technically, the digital techniques also potentially offer improved means of acquiring, storing, and handling images when comp…
