Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formulate a unified model that integrates elements across the eight models, and (4) empirically validate the unified model. The eight models reviewed are the theory of reasoned action, the technology acceptance model, the motivational...

A Fair Test Of The Effect Of A Shadow-Incompatible Luminance Gradient On The Simultaneous Lightness Contrast. Comment

P. Bressan & A. D. Logvinenko
Shadow-compatibility of simultaneous lightness contrast is discussed by Alexander D Logvinenko and Paola Bressan, with examples claiming to provide a test of the hypothesis.

Polymer-bound haloate(I) anions by iodine(III)-mediated oxidation ofpolymer-bound iodide: Synthetic utility in natural product transformations

Andreas Kirschning, Eike Kunst, Monika Ries, Lars Rose, Andreas Schönberger & Rudolf Wartchow
A set of polymer-attached hypervalent iodate(I) complexes were prepared from polymer-bound iodide anion by ligand transfer of acetate and trifluoro acetate present in the corresponding iodine(III) reagents onto the iodide anion. The synthetic versatility of these polymer-bound reagents in terms of efficacy and ease of workup is demonstrated for selected examples in natural product synthesis and natural product derivatization. Thus, iodoacetoxylation of glycals is the initial step for the preparation of two deoxygenated disaccharides which...

GOCE gradients in various reference frames and their accuracies

Jürgen Müller
The objective of GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) is the determination of the Earth's gravity field with high spatial resolution. The main science sensor (the gradiometer) measures differential accelerations, from which the gravitational gradients, i.e. the matrix of the second derivatives of the gravitational potential, are derived. Some of them (the diagonal components of the gravitational tensor) are observed with highest accuracy, 4 mE/?Hz in a frequency range from 5 mHz to...

Restructuring of the Ge(100) surface by Na chains

Wolfgang Ernst, K.-L. Jonas, V. Von Oeynhausen, Christoph Tegenkamp & Herbert Pfnür
The Na-induced surface structures on Ge(100) at concentrations below 0.1 monolayer (ML) have been investigated with low-energy electron diffraction and with scanning tunneling microscopy (STM). Annealing and partial desorption of higher coverages at temperatures between 650 and 680 K lead to the formation of characteristic chain structures, alternating between uncovered Ge dimer or double dimer rows and Na chains. The Na atoms have a preferential distance of three Ge lattice constants along the chains, but...

Formation of surface color centers at differently coordinated sites: MgO/Ag(1,1,19)

J. Kramer, Christoph Tegenkamp & Herbert Pfnür
In order to find criteria for discrimination between surface color centers at terraces and steps, and bulk color centers, the characteristic losses of these centers have been investigated by electron energy loss spectroscopy on an epitaxial MgO film grown on a Ag (1,1,19) surface. This film contains a significantly higher step density compared with a film grown on Ag(100). The generation of four distinct losses at 2.0, 2.4, 2.8, and 3.4 eV and a broad...
