Recently there has been growing interest in and debate about the relation between cognitive neuroscience and education. Our goal is to advance the debate beyond both recitation of potentially education-related cognitive neuroscience findings and the claim that a bridge between fields is chimerical. In an attempt to begin a dialogue about mechanisms among students, educators, researchers and pra...

Over the past decade, education reform and teacher training projects have spent a great deal of effort to create and support sustainable, scalable online communities of education professionals. For the most part, those communities have been created in isolation from the existing local professional communities within which the teachers practice. We argue that focusing on online technology solely...

Schools today face ever-increasing demands in their attempts to ensure that students are well equipped to enter the workforce and navigate a complex world. Research indicates that computer technology can help support learning, and that it is especially useful in developing the higher-order skills of critical thinking, analysis, and scientific inquiry. But the mere presence of computers in the c...

Schools play a key role in transmitting attitudes towards sexual diversity. Many studies stress the importance of teachers' and other professionals' attitudes towards gay men and/or lesbian women. This study evaluates attitudes and prejudices toward homosexuality in a sample of 254 elementary and high school teachers in Barcelona and its surrounding area. The results obtained using a scale of o...

High-reflective coatings are indispensable in order to manufacture mirrors with highest possible reflectivity. The maximum reflectivity can be achieved by all-dielectric coatings; however, the spectral bandwidth of these mirrors is limited. For astronomical applications metal based coatings (Al, Au, Ag) are commonly applied, as they allow high reflectivity and at the same time a broad spectral ...

Sea ice is an essential component of the global climate system since it influences and is influenced by changes and variations in the global energy balance and water cycle. In the context of decreasing SIE over the Arctic and an increasing area covered by the seasonal ice, spatial and temporal variations in thin ice especially its thickness are important research questions. The brightness tempe...

The limit sensitivity of interferometric gravitational wave antennas is set by the thermal noise in the dielectric mirror coatings. These are currently made of alternating quarter-wavelength high/low index material layers with low mechanical losses. The quarter-wavelength design yields the maximum reflectivity for a fixed number of layers, but not the lowest noise for a prescribed reflectivity....

Undoped, thin silicon films have been deposited at different temperatures on fused quartz substrates by low-pressure chemical vapor deposition. The heating of these films by continuous wave, argon-ion laser beam irradiation has been studied. In situ, normal incidence reflectivity measurements have been obtained at specified locations in the semiconductor films. Melting and recrystallization phe...

Airborne cloud radar and cloud microphysical data, collected in summertime stratus clouds off the Oregon coast, are analyzed to obtain an empirical threshold radar reflectivity above which drizzle can be expected in warm marine stratus. Such clouds, which are prevalent over the eastern subtropical oceans, have a profound impact on global climate. This study finds that the threshold reflectivity...
