text: The frequency-dependent dielectric function and the second-order polarizability
tensor of ferroelectric LiNbO3 are calculated from first principles. The calculations
are based on the electronic structure obtained from density-functional theory.
The subsequent application of the GW approximation to account for quasiparticle
effects and the solution of the Bethe-Salpeter equation for the stoichiometric
material yield a dielectric function that slightly overestimates the absorption
onset and the oscillator strength in comparison with experimental measurements.
Calculations at the level of the independent-particle approximation indicate that
these deficiencies are, at least, partially related to the neglect of intrinsic
defects typical for the congruent material. The second-order polarizability calculated
within the independent-particle approximation predicts strong nonlinear coefficients
for photon energies above 1.5 eV. The comparison with measured data suggests that
the inclusion of self-energy effects in the nonlinear optical response leads to
a better agreement with experiments. The intrinsic defects of congruent samples
reduce the optical nonlinearities, in particular, for the 21 and 31 tensor components,
further improving the agreement between experiments and theory.

text: We investigate the band dispersion and relevant electronic properties of rubrene
single crystals within the GW approximation. Due to the self-energy correction,
the dispersion of the highest occupied molecular orbital (HOMO) band increases
by 0.10 eV compared to the dispersion of the Kohn-Sham eigenvalues within the
generalized gradient approximation, and the effective hole mass consequently decreases.
The resulting value of 0.90 times the electron rest mass along the Γ-Y direction
in the Brillouin zone is closer to experimental measurements than that obtained
from density-functional theory. The enhanced bandwidth is explained in terms of
the intermolecular hybridization of the HOMO(Y) wave function along the stacking
direction of the molecules. Overall, our results support the bandlike interpretation
of charge-carrier transport in rubrene.

text: The GW approximation for the electronic self-energy is an important tool for
the quantitative prediction of excited states in solids, but its mathematical
exploration is hampered by the fact that it must, in general, be evaluated numerically
even for very simple systems. In this paper I describe a nontrivial model consisting
of two electrons on the surface of a sphere, interacting with the normal long-range
Coulomb potential, and show that the GW self-energy, in the absence of self-consistency,
can in fact be derived completely analytically in this case. The resulting expression
is subsequently used to analyze the convergence of the energy gap between the
highest occupied and the lowest unoccupied quasiparticle orbital with respect
to the total number of states included in the spectral summations. The asymptotic
formula for the truncation error obtained in this way, whose dominant contribution
is proportional to the cutoff energy to the power −3/2, may be adapted to extrapolate
energy gaps in other systems.

text: This study examines the relevance of financial and non-financial information
for the valuation of venture capital (VC) investments. Based on a hand-collected
data set on venture-backed start-ups in Germany, we investigate the internal due
diligence documents of over 200 investment rounds. We document that balance sheet
and income statement items capture as much economic content as verifiable non-financial
information (e.g. team experience or the number of patents) while controlling
for several deal characteristics (e.g. industry, investment round, or yearly VC
fund inflows). In addition, we show that valuations based on accounting and non-accounting
information yield a level of valuation accuracy that is comparable to that of
publicly traded firms. Further analyses show that the industry-specific total
asset multiples outperform the popular revenue multiples but lead to significantly
less accurate results than those obtained from the more comprehensive valuation
models. Overall, our findings might inform researchers and standard-setters of
the usefulness of accounting information for investment companies and provide
additional evidence to gauge the overall valuation accuracy in VC settings.

text: For the valuation of fast growing innovative firms Schwartz and Moon (Financ
Anal J 56:62–75, 2000), (Financ Rev 36:7–26, 2001) develop a fundamental valuation
model where key parameters follow stochastic processes. While prior research shows
promising potential for this model, it has never been tested on a large scale
dataset. Thus, guided by economic theory, this paper is the first to design a
large-scale applicable implementation on around 30,000 technology firm quarter
observations from 1992 to 2009 for the US to assess this model. Evaluating the
feasibility and performance of the Schwartz-Moon model reveals that it is comparably
accurate to the traditional sales multiple with key advantages in valuing small
and non-listed firms. Most importantly, however, the model is able to indicate
severe market over- or undervaluation from a fundamental perspective. We demonstrate
that a trading strategy based on our implementation has significant investment
value. Consequently, the model seems suitable for detecting misvaluations as the
dot-com bubble.

text: 'Standard equity valuation approaches (i.e., DDM, RIM, and DCF model) are
derived under the assumption of ideal conditions, such as infinite payoffs and
clean surplus accounting. Because these conditions are hardly ever met, we extend
the standard approaches, based on the fundamental principle of financial statement
articulation. The extended models are then tested empirically by employing two
sets of forecasts: (1) analyst forecasts provided by Value Line and (2) forecasts
generated by cross-sectional regression models. The main result is that our extended
models yield considerably smaller valuation errors. Moreover, by construction,
identical value estimates are obtained across the extended models. By reestablishing
empirical equivalence under non-ideal conditions, our approach provides a benchmark
that enables us to quantify the errors resulting from individual deviations from
ideal conditions, and thus, to analyze the robustness of the standard approaches.
Finally, by providing a level playing field for the different valuation approaches,
our findings have implications for other empirical settings, for example, estimating
the implied cost of capital. '

text: This article examines and extends research on the relation between the capital
asset pricing model market beta, accounting risk measures and macroeconomic risk
factors. We employ a beta decomposition approach that nests competing models with
different business risk proxies and allows to frame cross-model comparison. Because
model tests require estimated independent variables resulting in measurement error,
we empirically estimate three comparable model specifications with instrumental
variable estimators and for the first time provide thorough instrument diagnostics
in this setting. Correcting for the heretofore neglected weak instruments problem
we find that growth risk (i.e., the risk of firm sales variations that are inconsistent
with the market wide trends), is the business risk that explains cross-sectional
variations in market beta best.

text: Modelle Allgemeiner Didaktik sind in der Regel weder empirisch fundiert noch
ist ihr Verhältnis zum realen Planungshandeln von Lehrerinnen und Lehrern geklärt.
Theoretische Basis für empirische Studien zur Unterrichtsplanung sind selten allgemeindidaktische
Modelle, sondern eher psychologische Theorien. Auch die Forschungzu Aufgaben ist
bislang eher kognitionspsychologisch orientiert. Vor diesem Hintergrund knüpft
der vorliegende Beitrag an die allgemeindidaktische Aufgabenforschung an. Allerdings
erwies sich der Begriff der Aufgabe im Laufe des Forschungsprozesses als zu eng
bzw. voraussetzungsvoll und wurde daher zugunsten des Konzepts der Schüleraktivitäten
erweitert. Die zentrale Frage der explorativen Studie lautet demnach, wie Lehrerinnen
und Lehrer Schüleraktivitäten planen. Die Überlegungen wurden dabei mit der Methode
des Lauten Denkens erfasst und qualitativ inhaltsanalytisch ausgewertet. Erste
Ergebnisse zeigen, dass Lehrerinnen und Lehrer zwar implizit in ihrer Planung
einige der Dimensionen berücksichtigen, die mit allgemeindidaktischen Modellen
in Einklang stehen, dass aber noch ungenügend erforscht wurde, wie Schüleraktivitäten
in den subjektiven Planungsüberlegungen vorkommen.
