The techniques which have been employed for inversion of IR heterodyne measurements for remote sounding of stratospheric trace constituents usually rely on either geometric effects based on limb-scan observations (i.e., onion peel techniques) or spectral effects by using weighting functions corresponding to different frequencies of an IR spectral line. An experimental approach and inversion technique are discussed which optimize the retrieval of concentration profiles by combining the geometric and the spectral effects in an IR heterodyne receiver. The results of inversions of some synthetic ClO spectral lines corresponding to solar occultation limb scans of the stratosphere are presented, indicating considerable improvement in the accuracy of the retrieved profiles. The effects of noise on the accuracy of retrievals are discussed for realistic situations.

A young female orangutan that was maintained in a home-rearedlfree-ranging environment acquired 37 signs (Ameslan) after 19 months of training. Analysis and qualitative comparison of the initially produced signs revealed that an orangutan developed a vocabulary of signs in a manner similar to that of a chimpanzee and gorilla. This substantiates the general pongid ability to acquire manual signs.

PROBLEM This study assessed existing child-rearing attitudes in a sample population of licensed, full-time foster home mothers of Los Angeles County by comparing their attitudes with those of a comparable sample of biological mothers in a Well-Baby Clinic.METHOD Procedure. The instrument selected for assessing such attitudes was the Parent Attitude Research Instrument (PARI). The maternal form of the PARI wm selected for its value in assessing a wide variety of parental attitudes in a manner that allowed for straightforward statistical analysis and interpretation. Easily administered and consisting of 115 items that measure 23 different child-rearing attitudes, a tot,al raw score was calculated for every S on each of the 23 PARI attitude sub-scales. Means and standard deviations were calculated for each of the 23 scales and t-tests of difference between uncorrelated means for both the experimental group (foster mothers) and the control group ( Well-Baby Clinic mothers) were performed.
