Young children, 3 to 6 years’ old, were observed in two situations: (1) a traffic model, where they used dolls to enact the movements of two children on the way to and from day care; and (2) as they crossed a lightly trafficked, minor road in a situation analogous to that in the model. Atotal of 131 children participated. All were tested in the model situation (a), both on understanding of safety

This research focuses on representations of mobilities and their role in social networking on Facebook. Based on an ethnographic research design embedded in a grounded theory approach, the study investigates the mobility patterns of one Generation Y network. The analysis of 50 profiles in this network, including texts, photographs, photo albums and check-ins, suggests that Facebook fosters corpore

Characterization of directed differentiation of pluripotent stem cells towards therapeutically relevant cell types, including pancreatic beta-cells and hepatocytes, depends on molecular markers and assays that resolve the signature of individual cells. Pancreas and liver both have a common origin of anterior definitive endoderm (DE). Here, we differentiated human embryonic stem cells towards DE us

The authors have previously shown that one-particle calculations of X-ray spectra in simple metals give very different results depending on whether the core hole is taken into account or not. Guided by experiment and the dynamical theory of X-ray spectra developed by Nozieres and DeDominicis (ND) (1969) the authors have, however, also established the rule that rather realistic spectra can be obtai

Using delayed-coincidence techniques we have measured the natural radiative lifetimes of several S and D states in Rb and Cs. The states were excited by a pulsed dye laser from the first P state, populated using an rf discharge lamp.

Between knowledge and nonsense – the mysterious churches of Bornholm: A critical discussion of two books by Erling Haagensen, where he postulate a sacred geometry on Bornholm and a treasure hidden by the Templars in the round church of Österlars – or somewhere else.

Abstract in UndeterminedComplex stimuli and tasks elicit particular eye movement sequences. Previous research has focused on comparing between these scanpaths, particularly in memory and imagery research where it has been proposed that observers reproduce their eye movements when recognizing or imagining a stimulus. However, it is not clear whether scanpath similarity is related to memory performa

Risk of human papillomavirus (HPV) transmission during laser vaporisation of genital warts or loop electrode excision procedure is controversial. An oral rinse, a nasal swabs, history of HPV-related diseases and data on HPV exposure were collected from 287 employees at departments of dermato-venerology and gynaecology in Denmark. A mucosal HPV type was found among 5.8% of employees with experience

BACKGROUND: The importance of voltage-dependent conductances in sensory information processing is well-established in insect photoreceptors. Here we present the characterization of electrical properties in photoreceptors of the cockroach (Periplaneta americana), a nocturnal insect with a visual system adapted for dim light. RESULTS: Whole-cell patch-clamped photoreceptors had high capacitances and

Many insects use the pattern of polarized light in the sky for spatial orientation and navigation. We have investigated the polarization vision system in the desert locust. To create a common platform for anatomical studies on polarization vision pathways, Kurylas et al. (2008) have generated a three-dimensional (3D) standard brain from confocal microscopy image stacks of 10 male brains, using two

Why has multilateral cooperation developed in the intelligence field? Prior research has deemed such cooperation unlikely, irrelevant or even dangerous due to low gains and high risks. However, multilateral intelligence cooperation both exists and seems to be on the increase. This study aims to explain this puzzling development. Drawing on institutional theory, the author advances a model of inter
