Actual and Potential Pedagogical Use of Tablets in Schools
2013
This study reviews the potential of tablet technology for teaching and learning. In autumn 2012, we conducted a focused survey comprising quantitative and qualitative questions with Finnish teachers (N = 171, from 54 schools). We focused on perceived pedagogical opportunities and the actualized pedagogical potential of tablets at schools. The survey results indicate that the actual usefulness of tablets in schools was significantly less than what teachers perceived as the pedagogical potential. However, the results demonstrate the positive impact these devices are having on teaching and learning, as well as prompting changes in pedagogical perspectives. Teachers stated that tablets can dive…
Silver-loaded nanoparticles affect ex-vivo mechanical behavior and mineralization of dentin
2019
Background: The aim was to evaluate the effect of silver loaded nanoparticles (NPs) application on the triboscopic, crystallographic and viscoelastic properties of demineralized dentin. Polymethylmetacrylate-based NPs and Ag loaded NPs were applied on demineralized dentin. Material and Methods: Treated and untreated surfaces were probed by a nanoindenter to test viscoelasticity, and by atomic force microscopy to test nanoroughness and collagen fibril diameter. X-ray diffraction and transmission electron microscopy through selected area diffraction and bright-field imaging were also used. Results: Dentin treated with Ag-NPs attained the lowest complex modulus, and the highest tan delta value…
P056 Occupational exposure to metals and risk of breast, chronic lymphocytic leukaemia, colorectal, prostate, and stomach cancer in the MCC-spain cas…
2016
Arsenic, cadmium, chromium, and nickel are classified by IARC as human carcinogens (Group 1), while lead as a probable/possible carcinogen to humans (Group 2A). We explored associations between occupational exposure to metals and breast, chronic lymphocytic leukaemia (CLL), colorectal, prostate, and stomach cancer in the MCC-Spain population based case-control study. Methods The analyses were based on 3047 controls, and 1499 breast, 1539 colorectal, 332 CLL, 1070 prostate, and 382 stomach cancer cases. Occupational exposure to arsenic, cadmium, chromium, iron, lead and nickel was assessed using the MatEmEsp job-exposure matrix. Logistic regression models accounting for education, sex, geogr…
Birefringent porous silicon membranes for optical sensing
2012
In this work anisotropic porous silicon is investigated as a material for optical sensing. Birefringence and sensitivity of the anisotropic porous silicon membranes are thoroughly studied in the framework of Bruggeman model which is extended to incorporate the influence of environment effects, such as silicon oxidation. The membranes were also characterized optically demonstrating sensitivity as high as 1245 nm/RIU at 1500 nm. This experimental value only agrees with the theory when it takes into consideration the effect of silicon oxidation. Furthermore we demonstrate that oxidized porous silicon membranes have optical parameters with long term stability. Finally, we developed a new model …
Institutional logics and social enterprises: Entry mode choices of foreign hospitals in China
2020
When social enterprises, being defined by their social mission and profitability, internationalize, they need to\ud respond to institutional logics in the host country. By juxtaposing institutional logic and entry mode choice\ud literature, this paper shows how social enterprises accommodate different institutional logics when they enter\ud foreign markets. We collected data on Chinese healthcare reform, governmental policies and their changes, and\ud conducted 36 in-depth interviews and three expert group meetings. By analyzing five non-Chinese hospitals\ud entering China, we show how social enterprises, as hybrid organizations, respond to governmental, commercial,\ud and social institutio…
Investigation of insulin resistance in narcoleptic patients: dependent or independent of body mass index?

Alice Engel1,2, Jana Helfrich1, Nina Manderscheid1, Petra B Musholt3, Thomas Forst3, Andreas Pfützner3, Norbert Dahmen1,21Department of Psychiatry, University of Mainz, Germany; 2Fachklinik Katzenelnbogen, Katzenelnbogen, Germany; 3IKFE, Institute for Clinical Research and Development, Mainz, GermanyBackground: Narcolepsy is a severe sleep-wake cycle disorder resulting in most cases from a lack of orexin, the energy balance-regulating hormone. Narcoleptic patients have been reported to suffer from an excess morbidity of Type 2 diabetes, even after correction for their often elevated body mass index.Methods: To explore whether narcolepsy is specifically associated with a propensity …
Octave Spanning Supercontinuum in Titanium Dioxide Waveguides
2018
International audience; We report on the experimental generation of an octave-spanning supercontinuum in a 2.2 cm-long titanium dioxide optical waveguide with two zero dispersion wavelengths. The resulting on-chip supercontinuum reaches the visible wavelength range as well as the mid-infrared region by using a femtosecond fiber laser pump at 1.64 µm.
Semi-blind Source Extraction Methods: Application to the measurement of non-contact physiological signs
2018
Non-contact physiological measurements are highlydesirable in many biomedical fields such asdiagnosis of infants, geriartic patients, patients withextreme physical trauma, and fitness and well-being.Remote photoplethysmography is increasingly beingused for non-contact measurement of heart rate fromvideos which is one of the most common biomedicalproperty required for most medical diagnosis. Oneof the common techniques for performing remotephotoplethysmography involves using Blind SourceSeparation (BSS) methods to extract the cardiacsignal from video data.In this context, the objective of this thesis is todevelop different methods in the field of extractionand separation of sources by improv…
Sporta stunda kā 7.-8.klašu skolēnu veselīga uztura paradumu izvēles ierosinātājs
2017
Mūsdienās jauniešiem tiek sniegtas plašas iespējas kā pavadīt savu ikdienu, jāatzīst ka pie visām 21. gadsimta iespējam, tehnoloģijām vairums no viņiem izvēlas mazkustīgu dzīvesveidu, neievēro pareizus uztura paradumus, kas savukārt rada svara problēmas, kas var ietekmēt vispārējo veselību. Vairāku gadu garumā par to tiek runāts un veikti pētījumu taču situācija diemžēl neuzlabojas tieši otrādi statistika ar vien pieaug, tā tiek skaidrota ar informētības trūkumu, ar sociālekonomiskajiem apstākļiem ar pašas sabiedrības uzskatiem. Pētījuma mērķis ir novērot kādi ir Tukuma 2. Vidusskolas 7., 8. klašu skolēnu ķermeņa masas indekss, fizisko aktivitāšu un uztura paradumi, kā tos ietekmē pāri iela…
Moving from intention to behaviour: a randomised controlled trial protocol for an app-based physical activity intervention (i2be).
2022
IntroductionEfficacy tests of physical activity interventions indicate that many have limited or short-term efficacy, principally because they do not sufficiently build on theory-based processes that determine behaviour. The current study aims to address this limitation.Methods and analysisThe efficacy of the 8-week intervention will be tested using a three-condition randomised controlled trial delivered through an app, in women with a prior hypertensive pregnancy disorder. The intervention is based on the integrated behaviour change model, which outlines the motivational, volitional and automatic processes that lead to physical activity. The mechanisms by which the behaviour change techniq…
