Im Artikel wird anhand der internationalen Diskussion über Lehrerausbildung und mithilfe des Ansatzes der Phänomenographie ein Konzept zur Integration von Schülerlaboren in die Informatiklehramtsbildung vorgestellt, um so die Praxisbezüge der ersten Phase der Lehrerausbildung zu stärken. Gleichzeitig werden Grundlagen gelegt, um durch einen ‚forschenden Blick„ auf Unterricht Kompetenzen zur Pla...

In 1979 oral rehydration therapy (ORT) using oral rehydration salts (ORS) solution became the cornerstone of the global effort, initiated by WHO, to reduce deaths of young children from diarrhoea, then estimated at 4.6 million annually (1). National programmes to control diarrhoeal diseases (CDD) were eventually developed in more than 110 countries. These gave priority to ensuring an adequate s...

I estimate a dynamic model in which a board of directors and a CEO interact to set the levels of CEO incentives and e¤ort. The intent is to understand the e¤ect that CEO incentives have on …rm value. In the model incentive levels are the result of CEO risk aversion, the cost of CEO e¤ort, the e¤ect of CEO e¤ort on …rm value, the volatility of shocks to …rm value, and the preference a board has ...

Purpose. To evaluate the relationship between macular microstructures and visual function in retinitis pigmentosa (RP). Method. Fourier domain optical coherence tomography (FD-OCT) and Goldmann perimetry were used to examine 100 eyes of 100 RP patients. The preserved photoreceptor outer segment (PROS) length was measured at the horizontal and vertical high definition line scans. The PROS area w...

OBJECTIVES The purpose of this study was to determine whether the response to ventricular pacing during tachycardia is useful for differentiating atypical atrioventricular node re-entrant tachycardia (AVNRT) from orthodromic reciprocating tachycardia (ORT) using a septal accessory pathway. BACKGROUND Although it is usually possible to differentiate atypical AVNRT from ORT using a septal acces...

The impact of oral rehydration therapy (ORT) on the recent decline in diarrhoea mortality in the northeast of Brazil was studied. Proportionate infant mortality fell from 32% in 1980 to 17% in 1989 and infant deaths attributed to diarrhoea dropped from 41% to 25%, resulting in an overall reduction of 57%. Similar decreases were observed for children aged 1-4 years. Diarrhoea admissions also fel...

Two sources of workers’pro-social motivation have been considered in the literature: actionoriented altruism and output-oriented altruism. This paper presents evidence from a …eld experiment, which aims to identify and quantify them. The idea behind our experimental design is to measure in a precise way the level of e¤ort exerted in an environment that elicits purely sel…sh behavior and compare...

PURPOSE To compare optical coherence tomography (OCT) and histology of outer retinal tubulation (ORT) secondary to advanced age-related macular degeneration in patients and in postmortem specimens, with particular attention to the basis of the hyperreflective border of ORT. METHOD A private referral practice (imaging) and an academic research laboratory (histology) collaborated on two retrosp...
