Faced with a sluggish economy, car sales have been disappointing in recent years. Given this situation, it is critical that auto-dealerships shift the focus of their sales and marketing activities from attracting new customers to keeping the customers they already have. To develop advanced TMS, this move can be expected not only to reduce sales costs, but also contribute to healthy profits. To strengthen auto-dealerships, therefore, the author proceeds with researching customer satisfaction (CS) and customer loyalty (CL) as a way of boosting marketing effectiveness by using covariance structure analysis/structural equation modeling (SEM), clarifying the key factors that comprise CL, and help improve the marketing strategy. Then, as the application examples, the author focuses on the development and effectiveness for CS and CL by employing video unites customer behavior and maker's designing intentions (VUCMIN) and total direct mail management model (TDMMM).

With an interest to quest for transition metal-based halogenated double perovskites AB′B″X6 as high performance semiconducting materials for optoelectronics, this study theoretically examined the electronic structures, stability, electronic (density of states and band structures), transport (effective masses of charge carriers), and optical properties (dielectric function and absorption coefficients, etc.) of the series A2AgCrBr6 (A = K, Rb, Cs) using SCAN + rVV10. Our results showed that A2AgCrBr6 (A = Rb, Cs), but not K2AgCrBr6, has a stable perovskite structure, which was revealed using various traditionally recommended geometry-based indices. Despite this reservation, all the three systems were shown to have similar band structures, density of states, and carrier effective masses of conducting holes and electrons, as well as the nature of the real and imaginary parts of their dielectric function, absorption coefficient, refractive index, and photoconductivity spectra. The small changes observed in any specific property of the series A2AgCrBr6 were due to the changes in the lattice properties driven by alkali substitution at the A site. A comparison with the corresponding properties of Cs2AgCrX6 (X = Cl, I) suggested that halogen substitution at the X-site can not only significantly shift the position of the onset of optical absorption found of the dielectric function, absorption coefficient and refractive spectra of Cs2AgCrCl6 and Cs2AgCrI6 toward the high- and low-energy infrared regions, respectively; but that it is also responsible in modifying their stability, electronic, transport, and optical absorption preferences. The large value of the high frequency dielectric constants—together with the appreciable magnitude of absorption coefficients and refractive indices, small values of effective masses of conducting electrons and holes, and the indirect nature of the bandgap transitions, among others—suggested that cubic A2AgCrBr6 (A = Rb, Cs) and Cs2AgCrCl6 may likely be a set of optoelectronic materials for subsequent experimental characterizations.

A8Tl11 (A = alkali metal) compounds have been known since the investigations of Corbett et al. in 1995 and are still a matter of current discussions as the compound includes one extra electron referred to the charge of the Tl117− cluster. Attempts to substitute this additional electron by incorporation of a halide atom succeeded in the preparation of single crystals for the lightest triel homologue of the group, Cs8Ga11Cl, and powder diffraction experiments for the heavier homologues also suggested the formation of analogous compounds. However, X-Ray single crystal studies on A8Tl11X to prove this substitution and to provide a deeper insight into the influence on the thallide substructure have not yet been performed, probably due to severe absorption combined with air and moisture sensitivity for this class of compounds. Here, we present single crystal X-Ray structure analyses of the new compounds Cs8Tl11Cl0.8, Cs8Tl11Br0.9, Cs5Rb3Tl11Cl0.5, Cs5.7K2.3Tl11Cl0.6 and K4Rb4Tl11Cl0.1. It is shown that a (partial) incorporation of halide can also be indirectly determined by examination of the Tl-Tl distances, thereby the newly introduced cdd/cdav ratio allows to evaluate the degree of distortion of Tl117− clusters.

AbstractSingle crystals of α‐Cs3KBi2Mn4 (PO4)6Cl (I), β‐Cs3KBi2Mn4 (PO4)6Cl (II), and α‐Cs3KBi2Fe4 (PO4)6Cl (III) are synthesized in reactive CsCl/KCl molten‐salt media from Bi2O3, Mn2O3 (Fe2O3), and P4O10 in a molar ratio of 1:1:1 (I) or 2:1:1 (II) (800 °C, 4 d, 10—30% yield).

AbstractDas magnetische Verhalten von Cs2NaTmF6, Cs2KTmF6, Cs2RbTmF6 Cs2KTmCl6 und Cs2KTmBr6 wird im Temperaturbereich von 2, 9 bis 251, 3 K untersucht. Die magnetischen Daten werden mit einem früher entwickelten Modell interpretiert, bei dem der Einfluß des Kristallfeldes theoretisch durch das Angular‐Overlap‐Modell beschrieben ist. Die erhaltenen Werte des Angular‐Overlap‐Parameters eσ (R) für die einzelnen Verbindungen werden untereinander verglichen und diskutiert Die Energiewerte der Kristallfeldniveaus des 3H6‐Grundzustandes werden berechnet.
