Direct visualization of defect density waves in 2D.

A scanning tunneling microscopy investigation of the 1/3 of a monolayer alpha phase of Sn on Si(111) reveals a new low temperature phase, which is electronic and not structural. This phase consists of a one-dimensional incommensurate electronic wave that coincides with a periodic modulation of the population of the substitutional Si defects, i.e., a defect density wave.

[A methodological contribution to the knowledge on psychosocial alienation].

A methodological approach to the study of alienation at a psychological level is discussed. Owing to the methodological purpose of the research at stake, researchers paid attention to the fact that the questionnaire items had been written in the first person singular--a fact that encouraged researchers to work anew, on the hypothesis of the personal implication of subjects with the items contents. A conclusion was thus reached that an item written in first person singular dissuades subjects from telling what they think or feel actually, inducing subjects to produce social desirability-oriented answers.
