    Electronic structure and optical spectra of YBa2Cu3O7−δ thin films in the infrared and UV region (1992)
    Springer
    Applied physics 55 (1992), S. 192-195 
    Details
    ISSN: 1432-0630
    Keywords: 78.65.Ez ; 78.20.Ci ; 74.75.+t

    Notes: Abstract Optical reflectance of YBa2Cu3O7-δ thin films grown by laser ablation is measured within photon energies of 0.1 eV to 3.5 eV at room temperature. The spectra can be fit congruently with the anisotropic dielectric constants which take account of the intraband free carrier transition and interband transition. The anisotropic plasma frequencies are simulated to be ħεpl=2.18 eV and ħεch=2.80 eV contributed from free carriers on the plane and in the chain, respectively. The interband transition occurs near 2.5 eV and is pertinent to a rather broad line width.

    Indirect photometric detection of inorganic anions by microcolumn liquid chromatography using anthraquinone-disulfonate as visualization agent (1995)
    Springer
    Chromatographia 40 (1995), S. 379-381 
    Details
    ISSN: 1612-1112
    Keywords: Column liquid chromatography ; Indirect photometric detection ; Anthraquinone-disulfonate ion ; Inorganic anions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Disodium salts of several anthraquinone-disulfonic acids, which possess large molar absorptivity, were employed as the visualization agent for microcolumn ion chromatography with indirect photometric detection. Detection limits of inorganic anions were improved, e.g., concentration detection limits of chloride, nitrate and sulfate were 0.91–1.6 μmol L−1 at S/N=3, corresponding to mass detection limits of 18–32 fmol. The present system was applied to the determination of inorganic anions in tap water.

    Bile acids as stationary phase in liquid chromatography (1998)
    Springer
    Chromatographia 47 (1998), S. 183-188 
    Details
    ISSN: 1612-1112
    Keywords: Column liquid chromatography ; Bile acid aggregates as stationary phase ; Enantiomeric separation ; 1,1′-Binaphthyl-2,2′-diyl-hydrogenphosphate enantiomers ; Dansyl amino acids
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Bile acids chemically bonded onto aminopropylsilica have been employed as stationary phases in liquid chromatography. Bile acid aggregates were dynamically formed around molecules chemically anchored on the supports when the eluent contained bile salts. The bile salt aggregates achieved the separation of 1,1′-binaphthyl-2,2′-diyl-hydrogenphosphate enantiomers and dansyl amino acids.

    The Impact of Vocational Schooling on Human Capital Development in Developing Countries: Evidence from China (2016)
    Oxford University Press
    Details
    Publication Date: 2016-01-19
    Description: A number of developing countries are currently promoting vocational education and training (VET) as a way to build human capital and strengthen economic growth. The primary aim of this study is to understand whether VET at the high school level contributes to human capital development in one of those countries—China. To fulfill this aim, we draw on longitudinal data on more than 10,000 students in vocational high school (in the most popular major, computing) and academic high school from two provinces of China. First, estimates from instrumental variables and matching analyses show that attending vocational high school (relative to academic high school) substantially reduces math skills and does not improve computing skills. Second, heterogeneous effect estimates also show that attending vocational high school increases dropout, especially among disadvantaged (low-income or low-ability) students. Third, we use vertically scaled (equated) baseline and follow-up test scores to measure gains in math and computing skills among the students. We find that students who attend vocational high school experience absolute reductions in math skills. Taken together, our findings suggest that the rapid expansion of vocational schooling as a substitute for academic schooling can have detrimental consequences for building human capital in developing countries such as China.
