This paper looks at the nature of second language immersion learning and instruction through the lens of situated learning theory. This theory has strong relevance for language immersion practice and research. An emerging research program is introduced that is focused on the overlap of immersion learning and situated learning theory, and an initial study is discussed that explored how learners ...

The role of aldosterone suppression in mediating the natriuresis of water immersion was assessed in six normal male subjects. All subjects were studied on four occasions while they were in balance on a diet containing 150 mEq of sodium and 100 mEq of potassium daily: during a control period, following deoxycorticosterone acetate (DOCA) treatment for 24 hours (Cont+ DOCA), during water immersion...

To examine how repeated cooling of fingers with a rest pause schedule at work affects cold-induced vasodilatation (CIVD), pain and cold sensation in fingers, six healthy men aged 21 to 23 years immersed their left index fingers six times in stirred water at 10 degrees C for 10 minutes. After each cold-water immersion of the fingers, 5-minute rest pause was taken to observe the recovery process ...

A theory of diffraction-limited spot size is developed for infinity-corrected microscope optics. Previously reported formulae were originally derived using a single-lens system. In addition, the previously reported relationship between f -number and numerical aperture assumed a paraxial approximation and was limited to air-immersion lenses. Here, a new relationship between f -number and numeric...

Dual-language immersion programs have received a great deal of attention from parents, researchers, and policymakers. The supporters of dual-language immersion see the promise ofprovidingfirst-language instruction for children with nonEnglish-speaking backgrounds, while simultaneously offering monolingual children access to non-English languages. In this article, Guadalupe Vaidés concentrates o...

Whether spray or immersion fixation results in higher adequacy rates for thyroid fine-needle aspiration is not known. I compared 1-year adequacy rates, number of cells, and atypia rates for immersion fixation with split spray fixation and immersion. Adequacy rates increased from 71.9% (289/402) for complete immersion to 78.1% (332/425) with spray fixation of half of the slides (P = .02). The sp...

Despite the word's common usage by gamers and reviewers alike, it is still not clear what immersion means. This paper explores immersion further by investigating whether immersion can be defined quantitatively, describing three experiments in total. The first experiment investigated participants' abilities to switch from an immersive to a non-immersive task. The second experiment investigated w...

PURPOSE To compare 2 methods of axial length measurement, immersion ultrasonography and partial coherence interferometry, and to elucidate surgical outcomes based on immersion measurements. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS Axial length measurements in 50 cataractous eyes were obtained by optical biometry (IOLMaster, Zeiss Humphrey Systems) and immersion ultrasound ...

Given previous studies indicating a significant correlation between anxiety and presence, the purpose of this investigation was to explore the direction of the causal relationship between them. The sample consisted of 31 adults suffering from snake phobia. The study featured a randomized within-between design with two conditions and three counterbalanced immersions: (a) a baseline control immer...
