Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study investigates how companies across different industries emphasize themes within Integrated Reporting (IR), as promoted by the International Integrated Reporting Council (IIRC). As IR gains relevance for advancing Corporate Social Responsibility (CSR) and Environmental, Social, and Governance (ESG) disclosure, understanding sectoral ...

Distributions of Functionals of the two Parameter Poisson-Dirichlet Process [PDF]
The present paper provides exact expressions for the probability distribution of linear functionals of the two–parameter Poisson–Dirichlet process. Distributional results that follow from the application of an inversion formula for a (generalized) Cauchy–

Hierarchical Double Dirichlet Process Mixture of Gaussian Processes
, 2021 We consider an infinite mixture model of Gaussian processes that share mixture components between non-local clusters in data. Meeds and Osindero (2006) use a single Dirichlet process prior to specify a mixture of Gaussian processes using an infinite ...

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations
Contributions to Plasma Physics, EarlyView.ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

Target Tracking Method Based on Adaptive Prior Appearance Model
工程科学与技术, 2013 :To solve the drifting problem of a varying target object during target tracking, an adaptive prior appearance model was presented. The hierarchical Dirichlet process evolutionary clustering model and online boosting learning were combined into a ...

Bayesian cluster geographically weighted regression for spatial heterogeneous data
Royal Society Open ScienceSpatial statistical models are commonly used in geographical scenarios to ensure spatial variation is captured effectively. However, spatial models and cluster algorithms can be complicated and expensive.

On the Bayesian analysis of species sampling mixture models for density estimation [PDF]
, 2006 The mixture of normals model has been extensively applied to density estimation problems. This paper proposes an alternative parameterisation that naturally leads to new forms of prior distribution.
