“…Preliminary analysis was also done with the subjects meeting one, two, or three of the factors in the specific aptitude battery but it did not differ particularly from the final computation. The findings are consistent with the great majority of studies and research that has been done involving testing and the disadvantaged (Culhane, 1965, Somerfield and Fotzinger, 1969, and Mathis, 1969. They are not consistent if one assumes the disadvantaged or culturally different person to be the same as the norming sample but this, by definition, is not so.…”

A study was undertaken to attempt to relate selected defined factors to success in a Manpower Development Training Center program. Subjects were disadvantaged or culturally deprived adults who were referred to a nurse aide‐orderly training course that consisted of both vocational and remedial education phases. Factors studied were an evaluation by the referring counselor in the stated interest of an individual taking the training, previous employment history (compiled by both type and duration), formal educational level, age when completing the course, expressed attitudes toward the course while enrolled, and aptitude test results.

“…The extinction coefficient values for p-carotene and lycopene can be compared with the value obtained by Mathis [35] for lutein, a molecule similar to p-carotene. The value of emax was 4.0 X lo5 I/mole cm at 5 18 nm.…”

Abstract— –Pulse radiolysis has been used to excite the triplet states of β‐carotene (τ# 9μ sec) and lycopene (τ= 8μsec) in hexane solution, both in the presence and absence of naphthalene as a triplet sensitiser. The absorption spectra of both triplets have been measured in the range 430–550 nm and have thus been extended into the region of the corresponding singlet absorptions. The overlap of the triplet and singlet spectra is discussed in relation to in vivo studies. Extinction coefficients of 1.3±0.1 × 105 l/mole cm for β‐carotene triplet 515 nm and 3.9±0.2 × 105 l/mole cm for lycopene triplet at 525 nm were obtained. Isomerisation of the all‐trans polyenes used was detected and preliminary measurements indicate that the yield of isomerisation was greater than the triplet yield. The rate of triplet energy transfer from naphthalene to β‐carotene was estimated to be 1.5 × 1010 l/mole sec. The corresponding value for lycopene was 1.4× 1010 l/mole sec. The measured efficient quenching of triplet β‐carotene by oxygen may occur by an energy transfer mechanism, leading to the formation of singlet oxygen (1Δg. This would suggest that the triplet energy level of β‐carotene lies between 121 and 94 kJ mole‐1.

“…Similarly, inferences about aptitude should be clarified in light of behaviors used to define them. Mathis (1969) has described how aptitude tests can be real barriers for the disadvantaged if they are interpreted as abstract causes of behavior. In communicating test information, counselors need to teach clients to clarify the differences between observations and inferences when using constructs.…”
