Inflammatory sacroiliac joint pathology: evaluation of radiologic assessment techniques.

Recognition of sacroiliac disease has been integral to arthritis diagnostic approaches. However, intra- and inter-observer variation have been recognized as limiting factors in radiologic assessment of the sacroiliac joint. The assumption that such irregularly shaped joints can be radiologically assessed of the sacroiliac joint.

A simple method for converting point coordinates into along/away values for use in brachytherapy calculations.

Brachytherapy, the use of radioactive sources for the treatment of tumors, is an important tool in radiation oncology. Accurate calculations of the dose delivered to malignant and normal tissues are the responsibility of the medical physics staff. Independent calculations, to verify the results of a commercial treatment planning system, are an important part of a good quality-management system for brachytherapy, a Nuclear Regulatory Commission requirement.

Influence of day care experiences and demographic variables on social behavior in kindergarten.

Investigation of teacher ratings of kindergarten behavior indicated more negative scores for children who had attended day care. When demographic variables were included in the analysis, however, the relationship between day care and behavior was not significant. The need to consider children's ecological context in determining day care influence on developing social behavior is discussed.

Psychometric properties of the Wife Abuse Inventory.

It is estimated that approximately 50% of all married couples experience violence during their relationship (Lewis, 1985). The present study (N = 305) investigated the psychometric properties of the Wife Abuse Inventory (WAI), which was designed to identify women at risk for abuse. The WAI was found to be internally consistent, and evidence was obtained for the validity of the WAI as an indicator of the potential for being abused by one's spouse.
