Women in hospitality organizations are moving up the corporate ladder at a pace significantly outdistancing their colleagues of a few decades ago, but women managers selectively perceive overt and covert discriminatory resistance, from chauvinism to carefully-contrived covert prejudicial treatment constructed to insure a no-win situation. The authors attempted to determine if these discriminatory practices against equally well-trained, qualified, and experienced hospitality women middle managers do affect their perception of their career growth as compared to male counterparts

Jewish organization executive. Primarily autographs, photos, writings, speeches, and biographical material, collected by Bisno, relating to ca. 120 Jews who have attained prominence in American public life; together with papers (1923-32) from Congregation Talmud Torah of Los Angeles, letters (1928-37) relating to other Jewish organizations in Los Angeles, and 3 letters of Stephen S. Wise, dealing with the general Jewish situation in Europe in 1933 and with the question of Jewish participation in the 1936 Olympic games. Persons represented include Benjamin N. Cardozo, Abe Fortas, Felix Frankfurter, Henry Horner, Herbert H. Lehman, and Lewis L. Strauss.

We report on Raman and Ni K-edge x-ray absorption investigations of a NiS2-xSex (with x = 0.00, 0.50/0.55, 0.60, and 1.20) pyrite family. The Ni K-edge absorption edge shows a systematic shift going from an insulating phase (x = 0.00 and 0.50) to a metallic phase (x = 0.60 and 1.20). The near-edge absorption features show a clear evolution with Se doping. The extended x-ray absorption fine structure data reveal the evolution of the local structure with Se doping which mainly governs the local disorder. We also describe the decomposition of the NiS2-xSex Raman spectra and investigate the weights of various phonon modes using Gaussian and Lorentzian profiles. The effectiveness of the fitting models in describing the data is evaluated by means of Bayes factor estimation. The Raman analysis clearly demonstrates the disorder effects due to Se alloying in describing the phonon spectra of NiS2-xSex pyrites.

The synthesis of iodonium salts of the general formula [Cb>6b>Hb>5b>IR]+X-, where R is an alkyl group and x- is a stabilizing anion, was attempted. For the choice of R three groups were selected, whose derivatives are known to be sluggish in Sb>Nb>1 and Sb>Nb>2 substitutions: cyclopropyl, 7, 7 -dimethyl-1-norbornyl, and 9 -triptycyl. The synthetic routes followed along classical lines which have been exploited in recent years by Beringer and students. Ultimately, the object of the present study was to study the reactions of the above salts with nucleophiles. In none of the three cases, however, was it possible to isolate a stable salt. A thermodynamic argument suggests that this must be due to kinetic instability rather than thermodynamic instability. Only iodocyclopropane and 1-iodoapocamphane formed isolable iododichlorides.

Several methylated 2, 2-difluoronorbornanes were prepared with the intent of correlating fluorine -19 chemical shifts with geometric features in a rigid system. The effect of a methyl group on the shielding of a β -fluorine is dependent upon the dihedral angle; the maximum effect (an upfield shift of the resonance) occurs at 0° and 180°, whereas almost no effect is felt at a dihedral angle of 120°. The effect of a methyl group on a γ -fluorine is to strongly shift the resonance downfield when fluorine and methyl group are in a 1, 3 - diaxial-like relationship. Molecular orbital calculations of fluorine shielding in a variety of molecules were carried out using the formalism developed by Pople; the results are, at best, in modest agreement with experiment.

Radiolarian number and/or flux rates extracted from Holocene and fossil sediments are used to help detect the presence of, type of (weak or strong), and exact location of the depocenter under an El Niño. These data, along with known provenances of certain radiolarians, support an earlier model that suggests a weak El Niño is a northern and coupled expression of a more southerly strong component dominated by eastern tropical Pacific water underlain by California current and gyre water.

Government of Sri Lanka initiated a project for conducting a experimental skipjack fishery using modern pole and line method and an experimental fishery for live bait and small pelagic fish using purse seine and lampara nets, with the, assistance of UNDP and FAO. Accordingly, the survey for small pelagic fish varieties using the purse seine and lampara nets commenced in April, 1972 and will continue until the end of 1975. This paper is a preliminary report on the results of the survey carried out between Septernber 1972 to October 1978.
