3. Philosophic Orientation, Logical Consistency, and Teaching Attitudes of Urban and Suburban Teachers.

Author

Weinstock, H. R. and Turner, H. E.

Abstract

Increased interest in the problems associated with lower socio-economic urban schools has suggested possible differences between urban and suburban teachers. A Study was therefore undertaken to contrast the philosophic orientation, logical consistency, and teaching attitudes of elementary and secondary school teachers in two St. Louis school districts--one lower socio-economic and urban, the other, middle socio-economic and suburban. A total of 318 teachers responded to the GNC Scale of Logical Consistency in Ideas about Education and the Minnesota Teacher Attitude Inventory. Multivariate analyses of variance were used to ascertain differences between and with the two districts according to sex, age, degree, and teaching level. As a group, the suburban teachers were more logically consistent in relating their theoretical ideas to their practical views about education. The highest level was demonstrated by the suburban 20-29 age group. No differences were found between the districts in the maintenance of prescribed teaching attitudes by teachers. Results indicate that if logical consistency in educational ideas is desirable, more of the type of young teachers currently aspiring for suburban teaching should instead be encouraged to teach in urban schools.

12. Nondestructive evaluation of wires using high-temperature SQUIDs

Author

Weinstock, H., Tralshawala, N., and Claycomb, J.R.

Subjects
High temperature superconductors -- Research, Non-destructive testing -- Usage, Superconducting quantum interference devices -- Research, Business, Electronics, Electronics and electrical industries
Abstract

Research was conducted to evaluate the defects during the fabrication of single and multi-strand wire, particularly superconductive NbTi/Cu wire. An approach using superconducting quantum interference device magnetometry and low-frequency current injection was developed for the study. Results illustrate that it is not practical to detect inclusions that may be present during the drawing process. It is not clear, however, at what stage of the process the observed nonlinear behavior is introduced.

13. Magnetomechanical behavior of steel via SQUID magnetometry

Author

Subjects

Abstract

A direct current superconducting quantum interference device (SQUID) second-order magnetometer is used in studying the magnetomechanical behavior of steel bars subjected to stress-strain hysteretic cycles. The vertical component of the magnetic field above the bars are recorded using the SQUID magnetometer. Results indicate the presence of Barkhausen noise due to micromechanical hysteresis initiated by increasing stress.

14. Passive nondestructive evaluation of ferromagnetic materials during deformation using SQUID gradiometers

Author

Abstract

A method for the passive analysis of ferromagnetic materials subjected to tensile deformation is presented. The method uses a three-axes first order superconducting quantum interference device gradiometer to monitor the effects of tensile loading on the magnetic field and response of the ferromagnetic materials. The applicability of the proposed method was validated through an experiment involving cold-rolled steel specimens.
