Undergraduate Occupational Images and their Relationship to Selection of Academic Majors

The term stereotype was coined by columnist Walter Lippman who used it originally to refer to rigid and standardized pictures in the minds of people which persist because they provide the individual with a consistent picture of the world in which he lives and to which he must adjust; any effort to change the stereotype thus became an attack upon the world of the individual to be resisted with emotional intensity. Since its inception the term has come to be utilized in a variety of contexts but there is a tendency for each user to redefine it in relation to his own requirements. In the Dictionary of Sociology it is defined as a group-accepted image or idea, usually verbalized and charged with emotion. Simplified, even caricatured, conception of a character, personality, aspect of social structure, or social program which stands in place of accurate images in our minds

Continuum-plasma solution surrounding nonemitting spherical bodies

The classical problem of the interaction of a nonemitting spherical body with a zero mean-free-path continuum plasma is solved numerically in the full range of physically allowed free parameters (electron Debye length to body radius ratio, ion to electron temperature ratio, and body bias), and analytically in rigorously defined asymptotic regimes (weak and strong bias, weak and strong shielding, thin and thick sheath). Results include current-voltage characteristics as well as floating potential and capacitance, for both continuum and collisionless electrons. Our numerical computations show that for most combinations of physical parameters, there exists a closest asymptotic regime whose analytic solutions are accurate to 15% or better

THGEM operation in Ne and Ne/CH4

The operation of Thick Gaseous Electron Multipliers (THGEM) in Ne and Ne/CH4 mixtures, features high multiplication factors at relatively low operation potentials, in both single- and double-THGEM configurations. We present some systematic data measured with UV-photons and soft x-rays, in various Ne mixtures. It includes gain dependence on hole diameter and gas purity, photoelectron extraction efficiency from CsI photocathodes into the gas, long-term gain stability and pulse rise-time. Position resolution of a 100x100 mm^2 X-rays imaging detector is presented. Possible applications are discussed.Comment: Submitted to JINST, 25 pages, 33 figure
