    Notes: This paper compares two job classification methods for showing the appropriateness of cognitive tests in settings that were not involved in supplying data for a validity generalization analysis. One approach was an elaborate quantitative procedure that involved a lengthy job inventory and a multivariate item analysis. This approach was shown to be highly successful when applied to the responses from 1179 job inventories collected in 54 petroleum-petrochemical plants from 30 different companies. The other procedure involved simple job classification judgments by supervisors and incumbents. This latter approach was shown to be as effective, but was much less time consuming and costly. Professional and legal implications of these findings are discussed.

    Notes: The situational specificity hypothesis of selection procedure validity makes two predictions. The first is that variation in observed validities across settings is caused by real differences in what constitutes job performance. Validity generalization studies to date have provided disconfirming evidence for this prediction by showing that the observed variation is due to statistical and measurement artifacts. The second prediction is that if the situation (i.e., the organization, the setting, the job, the test and the criterion) is held constant, then validity findings will not vary from study to study. This article tests this prediction empirically using data from a unique series of studies reported by Bender and Loveless (1958). The results are contrary to the situational specificity hypothesis and consistent with the hypothesis that variation in observed validities is due to statistical and measurement artifacts that are unrelated to situations and settings. It is concluded that both major predictions of the situational specificity hypothesis have now been empirically disconfirmed.

    Description / Table of Contents: Azaborolinyl Complexes, X1). Synthesis and Properties of (1-tert-Butyl-2-methyl-η-1,2-azaborolinyl)carbonylmanganese and-molybdenum Complexes1-tert-Butyl-2-methyl-1,2-azaborolinyllithium (1) reacts with [CH3CN)3Mn(CO)3]PF6 to give (1-tert-butyl-2-methyl-η-1,2-azaborolinyl)tricarbonylmanganese (2). Neutral 1-tert-butyl-2-methyl-1,2-azaboroline (3) and Mo(CO)6 form π-ally(1-tert-butyl-2-methyl-η-1,2-azaborolinyl)-dicarbonylmolybdenum (4). The formation of the allyl group is due to the decomposition of an azaborolinyl ring under the reaction conditions. 2 and 4 are characterized by mass, IR, and NMR spectra. 4 could be investigated by X-ray analysis. Orthorhombic, space group Pbca, Z = 8, a = 1697.4(9), b = 1441.8(5), c = 1219.4(7) pm. The chirality of the azaborolinyl ring causes the formation of enantiomers which exist as a racemate in the crystal.
    Notes: 1-tert-Butyl-2-methyl-1,2-azaborolinyllithium (1) reagiert mit [(CH3CN)3Mn(CO)3]PF6 zum (1-tert-Butyl-2-methyl-η-1,2-azaborolinyl)tricarbonylmangan (2). Neutrales 1-tert-Butyl-2-methyl-1,2-azaborolin (3) und Mo(CO)6 bilden π-Allyl(1-tert-butyl-2-methyl-η-1,2-azaborolinyl)-dicarbonylmolybdän (4). Die Bildung der Allygruppe ist auf den Zerfall eines Azaborolin-Ringes unter den Reaktionsbedingungen zurückzuführen. 2 und 4 werden durch Massen-, IR- und NMR-Spektren charakterisiert. Von 4 konnte eine Röntgenstrukturanalyse durchgeführt werden: orthorhombisch, Raumgruppe Pbca, Z = 8, a = 1697.4(9), b = 1441.8(5), c = 1219.4(7) pm. Die Chiralität des Azaborolinyl-Ringes bedingt die Bildung von Enantiomeren, die im Kristall als Racemat vorliegen.
