SiOx nanowire emission with changes in the vapor pressure of Sn metal results in a screw motion of SiOx nanowires in a closed system consisting of Sn and SiOx. A convoluted flouncing-off process is elucidated here, in which the elementary particles are not electrons, but nanowires. In order to understand the unprecedented synthetic phenomena, the system that emits SiOx nanowires is compared with tungsten electron gun by comparing the component, functionalization, and theoretical background of both the techniques. The results so obtained, which are the first of its kind, open the way not only to produce three-dimensional micro- and nano-structures from one-dimensional nanostructures without requiring any additional artificial manipulation process but also to focus them onto a desired small region for elaborate deposition.

The synaptic connections in cat retina that link photoreceptors to ganglion cells have been analyzed quantitatively. Our approach has been to prepare serial, ultrathin sections and photograph en montage at low magnification (˜2000X) in the electron microscope. Six series, 100-300 sections long, have been prepared over the last decade. They derive from different cats but always from the same region of retina, about one degree from the center of the visual axis. The material has been analyzed by reconstructing adjacent neurons in each array and then identifying systematically the synaptic connections between arrays. Most reconstructions were done manually by tracing the outlines of processes in successive sections onto acetate sheets aligned on a cartoonist's jig. The tracings were then digitized, stacked by computer, and printed with the hidden lines removed. The results have provided rather than the usual one-dimensional account of pathways, a three-dimensional account of circuits. From this has emerged insight into the functional architecture.

The relation between authoritarianism and social dominance orientation was analyzed, with authoritarianism measured using a three-dimensional scale. The implicit multidimensional structure (authoritarian submission, conventionalism, authoritarian aggression) of Altemeyer’s (1981, 1988) conceptualization of authoritarianism is inconsistent with its one-dimensional methodological operationalization. The dimensionality of authoritarianism was investigated using confirmatory factor analysis in a sample of 713 university students. As hypothesized, the three-factor model fit the data significantly better than the one-factor model. Regression analyses revealed that only authoritarian aggression was related to social dominance orientation. That is, only intolerance of deviance was related to high social dominance, whereas submissiveness was not.
