This paper proposes a novel theoretical framework to model the dynamics of organizational mortality. The main theoretical contribution is a clarification of the relations between organizational fitness, endowment, organizational capital and mortality hazard. If the mortality hazard is a function of the stock of organizational capital, and the rate of accumulation of organizational capital is a ...

Default probability distributions are often defined in terms of their conditional default probability distribution, or their hazard rate. By their definition, they imply a unique probability density function. The applications of default probability distributions are varied, including the risk premium model used to price default bonds, reliability measurement models, insurance, etc. Fractional p...

We calculate the coefficient of bulk viscosity by considering the non-leptonic weak interactions in the cores of hybrid stars with both hyperons and quarks. We first determine the dependence of the production rate of neutrons on the reaction rate of quarks in the non-leptonic processes, that is Γn = KsΓs + ΓΛ + 2ΓΣ− . The conversion rate, Ks in our scenario is a complicated function of baryon n...

Fires will become an increasingly frequent perturbation even under the conditions of mild climate zone and interfere with agricultural landscape. Fire is a natural phenomenon, depending on ecosystems, vegetation may develop contribute to occurrence spread fire. Vegetation sour cherry orchard located in climatically dry South Moravian Region, Czech Republic (CR), was evaluated. assessment perfor...

The objective of this study was to examine the properties of Bayes estimators of the parameter, reliability function and hazard rate under the symmetric and asymmetric loss functions for the inverted exponential model. The Bayes predictive interval and the Bayes estimate of shift point are also determined. A simulation study was carried out to study the properties of the Bayes estimators. Intro...

This paper proposes a discrete-time hazard regression approach based on the relation between hazard rate models and excess over threshold models, which are frequently encountered in extreme value modelling. The proposed duration model employs a exible link function and incorporates the grouped-duration analogue of the wellknown Cox proportional hazards model and the proportional odds model as s...
