Decomposing venture evaluation: Learning about belief formation
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Evaluating early‐stage ventures is difficult because observable signals of future quality are weak and noisy. How closely are evaluators' assessments related to venture quality, and do their subjective judgments add to the information already available about a venture?

Safety Science and Technology, EarlyView.By integrating game theory‐based combined weighting with a system dynamics model, this study systematically reveals the dominant role of agility and adaptability in the resilience of post‐disaster emergency material supply chains. ABSTRACT In light of the intricate dynamics and uncertain risk parameters inherent in the emergency materials supply chains,

Spatial circular matrices, with applications [PDF]
The cumulants of the quadratic forms associated to the so-called spatial design matrices are often needed for inference in the context of isotropic processes on uniform grids.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization
CAAI Transactions on Intelligence Technology, EarlyView.Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

, 2020 Large complex systems tend to develop universal patterns that often represent their essential characteristics. For example, the cumulative effects of independent or weakly dependent random variables often yield the Gaussian universality class via the ...

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.

Social and emotional pathways to shame reduction: An RCT with preservice teachers
British Journal of Educational Psychology, EarlyView.Abstract Background Shame is an unpleasant, activating emotion that has been shown to undermine learners' motivation and achievement and identity development in mathematics education. Recent studies have implemented positive psychology interventions (PPIs) to reduce preservice teachers' shame in mathematics, with promising quantitative outcomes ...

, 2023 We define a random commuting $d$-tuple of $n$-by-$n$ matrices to be a random variable that takes values in the set of commuting $d$-tuples and has a distribution that is a rapidly decaying continuous weight on this algebraic set.
