Measuring specialty indecision among career-decided students
Increasing numbers of career-decided students in professional and graduate schools have difficulty choosing a specialty. To begin to examine this problem, a measure of specialty indecision was devised by changing the Career Decision Scale items to deal with specialty indecision rather than career indecision. The scale was then administered to 567 medical students along with measures of vocational development and exploratory behavior. Initial evaluation of the psychometric properties of the Specialty Indecision Scale indicate that it is internally consistent, relates more to specialty choice than to career choice, and inversely relates to both vocational development and exploratory behavior. A factor analysis of the scale items extracted four factors that reflect cognitive, conative, criterion, and implementation restraints on the decision-making process. The Specialty Indecision Scale seems to be useful for diagnostic and research purposes in the study and treatment of specialty indecision.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25480/1/0000020.pd
Probing liquid surface waves, liquid properties and liquid films with light diffraction
Surface waves on liquids act as a dynamical phase grating for incident light.
In this article, we revisit the classical method of probing such waves
(wavelengths of the order of mm) as well as inherent properties of liquids and
liquid films on liquids, using optical diffraction. A combination of simulation
and experiment is proposed to trace out the surface wave profiles in various
situations (\emph{eg.} for one or more vertical, slightly immersed,
electrically driven exciters). Subsequently, the surface tension and the
spatial damping coefficient (related to viscosity) of a variety of liquids are
measured carefully in order to gauge the efficiency of measuring liquid
properties using this optical probe. The final set of results deal with liquid
films where dispersion relations, surface and interface modes, interfacial
tension and related issues are investigated in some detail, both theoretically
and experimentally. On the whole, our observations and analyses seem to support
the claim that this simple, low--cost apparatus is capable of providing a
wealth of information on liquids and liquid surface waves in a non--destructive
way.Comment: 25 pages, 12 figures, to appear in Measurement Science and Technology
