    Notes: On lowering the chemical potential of diatomic oxygen, the compound YBa2Cu4O8 was found to decompose into a mixture of YBa2Cu3O6+x and CuO. The equilibrium oxygen potential corresponding to this decomposition has been measured from 870 to 1150 K using a solid-state cell incorporating yttria-stabilized zirconia as the solid electrolyte and pure oxygen at a pressure of 1.01×105 Pa as the reference electrode: Pt, O'2||YBa2Cu4O8+YBa2Cu3O6+x+CuO(parallel)(Y2O3) ZrO2(parallel)O2(1.01×105 Pa), Pt. The low oxygen potential boundary for the stability of YBa2Cu4O8 can be represented by ΔμO2=−238 900+207.7 T(±800) J mol−1. At the standard pressure of oxygen (1.01×105 Pa) the decomposition occurs at 1150 K.

    Notes: This paper analyses the differences between private and public sector organisations in Denmark in relation to the penetration of holistic management models, how companies achieve excellent results and the empirical weight structure of the European Foundation for Quality Management (EFQM) excellence model. The results show that the penetration of holistic management models is greater among public organisations. Furthermore private and public organisations do not achieve excellent results in the same way. Private companies put higher emphasis on the systems dimension whereas public organisations put higher emphasis on the people dimension. In relation to the empirical weight structure of the EFQM excellence model two significant differences were found. Private companies put higher emphasis on the criteria "leadership" and "policy and strategy" than public organisations.

    Measuring employee assets - The Nordic Employee Index (2004)
    Bradford : Emerald
    Business process management journal 10 (2004), S. 537-550

    Topics: Economics
    Notes: Based on a review of the literature within the field of job satisfaction and organizational commitment this paper proposes a generic model for measuring employee perceptions. The model consists of seven latent constructs operationalised through 29 manifest indicators. This model is subsequently tested on data from a questionnaire survey to which approximately 9,600 employees from the Nordic countries responded. The statistical technique applied for this analysis is partial least squares (PLS), which is well suited for structural equation modelling when the focus is on prediction. The results support the structure of the suggested generic model but reveals differences between the Nordic countries with regard to strength of the relationships as well as the average case value of the seven latent constructs.

    Topics: Economics
    Notes: This paper studies differences in job satisfaction and intrinsic work motivation between employees with different characteristics. Based on a study of the literature assumptions regarding these differences are developed and tested on data from a survey in the Nordic countries. In this survey 9,623 employees from randomly selected households in the Nordic countries participated. Among the findings are that Danish workers were found to be the most satisfied and that there is no difference between the genders with respect to job satisfaction in the Nordic countries.

    The criterion weights of the EFQM excellence model (2001)

    Notes: This paper examines the weight structure of the EFQM excellence model. This is done through a survey among 756 chief executive officers from Danish companies who responded to a self-assessment questionnaire. The data from this survey have been analysed through factor score regression based on confirmatory factor analysis on 5,000 bootstrapped samples. The analysis shows that the perceived criterion weights vary from the current allocation in the EFQM excellence model. This deviation is so substantial that the allocation of weights between the enabler and the result block vary considerably from the actual allocation in the EFQM excellence model. Furthermore, it seems as if Danish companies perceive the enabler criteria as equally important but this is not the case for the result criteria.

    Trends in EFQM criterion weights; the case of Denmark 1998-2001 (2002)

    Notes: This paper examines the criterion weights of the EFQM excellence model. More and more research indicates that the official criterion weights from EFQM do not correspond with the way companies are working. This, of course, raises the question whether or not it makes any sense to compare companies according to an arbitrary weight structure, which has never been empirically tested? In this paper the criterion weights are estimated through the use of a factor scores regression based on confirmatory factor analysis of a number of bootstrapped samples. This estimation procedure is applied on data collected among Danish companies which responded to a self-assessment questionnaire covering the EFQM excellence model in each of the years 1998-2001. The overall conclusions are that the allocation of weights is fairly stable for most of the criteria except for one. The weight allocated to "People results" is significantly lower in 2001 than in 1999 and 1998.

    The mobility of oxygen ions in CaF2 (1990)
    Springer
    Journal of applied electrochemistry 20 (1990), S. 294-300 
    Details
    ISSN: 1572-8838

    Notes: Abstract The a.c. conductivity of CaF2 samples containing a fine dispersion of CaO particles has been measured in the temperature range 630 to 1100 K. The conductivity of the dispersed solid electrolyte is two orders of magnitude higher than that for pure polycrystalline CaF2 in the middle of the temperature range. Transport measurements on pure single crystals of CaF2 and polycrystalline samples, with and without CaO dispersion, using Fe+FeO and pure Fe as electrodes, clearly indicate that fluorine ions are the only migrating ionic species with a transport number of almost unity, contrary to the suggestion of Chou and Rapp [1, 2]. The enhanced conductivity of the dispersed solid electrolyte probably arises from two effects. A small solubility of oxygen in CaF2 results in an increase in the fluorine vacancy concentration and conductivity. Adsorption of fluorine ions on the surface of the dispersed particles of CaO results in a space charge region around each particle with enhanced conductivity. Measurements on a galvanic cell incorporating CaF2 as the solid electrolyte and oxide electrodes show that the e.m.f. is a function of the activity of CaO at the electrode/electrolyte interface. The response to an oxygen potential gradient is, therefore, through an exchange reaction, which establishes an equivalent fluorine potential at the electrode/electrolyte interface.

    Use of the Nasicon/Na2SO4 couple in a solid state sensor for SO x (x=2,3) (1988)

    Notes: Abstract The e.m.f. of a concentration cell for SO x (x=2,3)-O2 incorporating Nasicon as the main solid electrolyte has been measured in the temperature range 720 to 1080 K. The cell arrangement can be represented as, $$Pt, O'_2 + SO'_2 + SO'_3 \left| {Na_2 SO_4 \left\| {\left. {Nasicon} \right\|} \right.} \right.\left. {Na_2 SO_4 } \right|SO''_3 + SO''_2 + O''_2 , Pt$$ The Na2SO4 acts both as an auxiliary electrode, converting chemical potentials of SO x and O2 to equivalent sodium potentials, and as an electrolyte. The presence of Na2SO4 provides partial protection of Nasicon from chemical reaction with gas mixtures containing SO x . The open circuit e.m.f. of the cell is in close agreement with values given by the Nernst equation. For certain fixed inlet gas compositions of SO2+O2, the e.m.f. varies non-linearly with temperature. The intrinsic response time of the cell to step changes in gas composition is estimated to vary from ∼2.0 ksec at 723K to ∼ 0.2 ksec at 1077K. The cell functions well for large differences in partial pressures of SO3(p″SO 3/p′SO 3≈104) at the electrodes.

    Notes: Abstract The open circuit potentials of the galvanic cell,Pt (or Au)¦(Ar + H2S + H2)′∥CaS + ZrO2(CaO)∥ (Ar + H2S+ H2)″£t (or Au) has been measured in the temperature range 1000 to 1660 K and PH2S:PH 2 ratios from 1.73×10−5 to 2.65×10−1. The solid electrolyte consists of a dispersion of calcium sulphide in a matrix of calcia-stabilized zirconia. The surface of the electrolyte is coated with a thin layer of calcium sulphide to prevent the formation of water vapour by reaction of hydrogen sulphide with calcium oxide or zirconia present in the electrolyte. The use of a ‘point electrode’ with a catalytically active tip was necessary to obtain steady emfs. At low temperatures and high sulphur potentials the emfs agreed with the Nernst equation. Deviations were observed at high temperatures and low sulphur potentials, probably due to the onset of significant electronic conduction in the oxide matrix of the electrolyte. The values of oxygen and sulphur potentials at which the electronic conductivity is equal to ionic conductivity in the two-phase electrolyte have been evaluated from the emf response of the cell. The sulphide-oxide electrolyte is unsuitable for sulphur potential measurements in atmospheres with high oxygen potentials, where oxidation of calcium sulphide may be expected.

    Notes: Abstract Single phase sodiumβ-alumina solid electrolyte was found to undergo isothermal phase separation in electrochemical cells, where a large oxygen potential gradient was imposed across the electrolyte and electrodes, not reversible to sodium ions, were short circuited. The experimental conditions and evidence of decomposition are outlined and a thermodynamic explanation for the phenomenon is given. This finding may lead to new methods for making multi-layered ceramic materials involving ionic conductors.
