Socialization forces and the stability of work values from late adolescence to early adulthood.

The present report is of findings from a longitudinal study of work values. The findings relate to four important areas, (a) the significance of parental socialization in the formation of intrinsic and extrinsic work values, (b) the effect of early employment on intrinsic and extrinsic work values, respectively, (c) the differential effects of these social experiences across ethnic and gender groups, (d) and the stability of intrinsic and extrinsic work values from late adolescence to the early years of adulthood. In a sample of 3290 African American and Caucasian students, young people consistently placed greater emphasis on intrinsic than on extrinsic work values. There was a decline in extrinsic work values between adolescence and the early years of adulthood. When parents held high aspirations, their children placed greater emphasis on work orientations. Race had a more significant influence on work values than either socioeconomic status or employment experience.

Triple-head SPECT with 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG): initial evaluation in oncology and comparison with FDG PET.

PURPOSE: In patients with cancer, performance was assessed of a commercially available triple-head gamma camera fitted with ultra-high energy parallel-hole collimators performing single photon emission computed tomography (SPECT) with 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG). Results were compared with those of positron emission tomography (PET) with FDG. MATERIALS AND METHODS: Performance characteristics were first determined in phantom studies for FDG PET and triple-head gamma camera SPECT systems. In 13 patients with malignancies, FDG PET was followed by SPECT of the same region, and imaging results were independently assessed. RESULTS: Sensitivity of the PET and SPECT systems was 58.3 counts/MBq/min and 4.5 counts/MBq/min, respectively. Reconstructed spatial resolution was approximately 7 mm for PET and 20 mm for SPECT. All known cancer foci were detected at PET. SPECT depicted 11 of the 22 lesions detected at PET, but only five of the 14 lesions less than 3 cm in diameter. CONCLUSION: FDG SPECT performed with a specially collimated triple-head gamma camera depicted some cancers but had an unacceptably low sensitivity compared with PET for lesions less than 3 cm in diameter. PET is preferable for detecting small cancers.

Note on assessing a mentor program.

To clarify the literature on mentor programs, self-esteem and grade point average after such a program were assessed for 30 boys and 46 girls in Grade 11 from 2 high schools. Mixed findings were discussed in terms of possible influences.
