We develop a theoretical framework explaining why and how business owning families (BOF) engage in impact investing. Despite its exponential growth, the burgeoning field investing is still subject to competing interpretations varying practices. Building on proposed by Nason et al. (2019b), we argue that BOF’s frame of reference (backward vs. forward looking internally externally oriented) const...

The recirculation fraction of intramyocardial Ca(2+) (RF) has conventionally been obtained from the monotonic decay of postextrasystolic potentiation (PESP). The used assumption is that the decay is exponential. However, we have found that PESP usually decays in alternans even at spontaneous heart rates (>100 beats/min) in excised, cross-circulated canine heart preparations under normal coronar...

We discuss the relationship between the statistical embedding curvature [1, 2] and the logarithmic regret [11] (regret for short) of the Bayesian prediction strategy (or coding strategy) for curved exponential families and Markov models. The regret of a strategy is defined as the difference of the logarithmic loss (code length) incurred by the strategy and that of the best strategy for each dat...

A new sigmoid growth equation is presented for curve-fitting, analysis and simulation of growth curves. Like the logistic growth equation, it increases monotonically, with both upper and lower asymptotes. Like the Richards growth equation, it can have its maximum slope at any value between its minimum and maximum. The new sigmoid equation is unique because it always tends towards exponential gr...

microalgal growth curve, after the exponential phase, shows a stationary phase where algalbiomass production is inhibited and remains constant by some factors such as nutrientdepletion and intrinsic behavior. the present study is concerned with evaluating effects ofthe culture medium condition and intrinsic behavior on biomass production by dunaliellatertiolecta. to this end, effect of ph, nutr...

BACKGROUND Data on body composition in infancy may improve the understanding of the relation between variability in fetal and infant growth and disease risk through the life course. Although new assessment techniques have recently become available, body composition is rarely described in infants from low-income settings. OBJECTIVE The aim of this study was to provide reference data for fat ma...

Exponential interpolation is a problem in mathematics which can have very useful results in many areas. One area which is particularly of interest here is using exponential interpolation to model human chorionic gonadotropin (hCG) levels in women with gestational trophoblastic disease as it has been previously reported that the hCG measurements in these women follow an exponential curve.

Our interest is to characterize the spline-like integer-shift-invariant bases capable of reproducing exponential polynomial curves. We prove that any compact-support function that reproduces a subspace of the exponential polynomials can be expressed as the convolution of an exponential B-spline with a compact-support distribution. As a direct consequence of this factorization theorem, we show t...
