KONA Powder and Particle Journal, 2014 A statistical model of the distribution of the contact number for a binary mixture in an incompletely mixed state is introduced. The model is derived from the beta-binomial model proposed by Yoshizawa and Shindo3 ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines climate change risk disclosure in the global energy sector, where firms face intense stakeholder scrutiny and legitimacy pressures. We develop a novel domain‐specific textual analysis measure to capture climate change risk disclosures, improving on prior approaches based on generic environmental terminology.

A note on empirical sample distribution of journal impact factors in major discipline groups [PDF]
What type of statistical distribution do the Journal Impact Factors follow? In the past, researchers have hypothesized various types of statistical distributions underlying the generation mechanism of journal impact factors. These are: lognormal, normal,

Journal of Consumer Behaviour, EarlyView.ABSTRACT This research examines how the disclosure of production cues interacts with corporate social responsibility cues to influence social media engagement in luxury fashion. Two complementary field studies analyse marketer‐generated Facebook posts from luxury fashion brands, providing large‐scale empirical evidence of a real‐world impact on ...

Restricted Tweedie stochastic block models
Canadian Journal of Statistics, EarlyView.Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

A goodness‐of‐fit test for regression models with discrete outcomes
Canadian Journal of Statistics, EarlyView.Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.
