Retraction: Sensing risk, fearing uncertainty: systems science approach to change
- BusinessFront. Comput. Neurosci.
There are two attributes of systems science that are especially relevant to this research: one—it offers a method for creating a structural context with a guiding path to pragmatic knowledge; and, two—it gives pre-eminence to sensory input capable to register, evaluate, and react to change.
The Efficient Market Hypothesis and the Fractal Market Hypothesis: Interfluves, Fusions, and Evolutions
- BusinessSAGE Open
The fractal market hypothesis (FMH) is one of the frontier theories of emerging finance and nonlinear science. The relationship between the FMH and the efficient market hypothesis (EMH) is easy to be…
Sensing Risk, Fearing Uncertainty: Systems Science Approach to Change
Change is dynamic, ever-present, never isolated, and of variable impact; it reflects innumerable relationships among contextual systems; change can be perceived as risk or uncertainty depending upon how the assessment is made.
Investment Horizon Dependent CAPM: Adjusting Beta for Long-Term Dependence
Financial basics and intuition stresses the importance of investment horizon for risk management and asset allocation. However, the beta parameter of the Capital Asset Pricing Model (CAPM) is…
ii From Gaussian to Paretian Thinking : Causes and Implications of Power Laws in Organizations
While normal distributions and related current quantitative methods are still relevant for some organizational research, the growing ubiquity of power laws signifies that Pareto rank/frequency…
Beyond Gaussian averages: redirecting international business and management research toward extreme events and power laws
Practicing managers live in a world of ‘extremes’, but international business and management research is based on Gaussian statistics that rule out such extremes. On occasion, positive feedback…
Four Ways to Scale Up: Smart, Dumb, Forced, and Fumbled
Modularity and speed are the answer to effective delivery – whether you are a small startup or Elon Musk trying to grow Tesla and SpaceX or Jeff Bezos scaling up Amazon – or you are the US, UK, Chinese, or other government trying to increase power production, expand your infrastructure, or make your health, education, and social services work better.
Generalized heat diffusion equations with variable coefficients and their fractalization from the Black-Scholes equation
- Physics, MathematicsCommunications in Theoretical Physics
In this study, we prove that modified diffusion equations, including the generalized Burgers’ equation with variable coefficients, can be derived from the Black-Scholes equation with a time-dependent…

This study aims to introduce a new theoretical framework for capital markets understanding, reconciling findings from various disciplines such as anthropology, psychology, biology, statistics and…
Exploring the scaling law of geographical space: Gaussian versus Paretian thinking
- Environmental ScienceEuropean Journal of Soil Science
A debate has occurred concerning the laws of scale and the fractal nature of geographical space. Biodiversity and pedodiversity studies show the emergence of fractal structures such as taxa‐area…
