To be or not to be? About the copula system in Buli (Gur) [PDF]

open access: yes, 2008
This talk concerns the copula system in Buli, a Ghanaian language which has also been attested in Bahia (Rodrigues 1935, Zwernemann 1968). Special focus will be put on the categorization of two copula-reminiscent elements for which I will propose a ...

Effects of extreme heat events on crop revenues for U.S. corn and soybeans

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Extreme weather events have nuanced implications for crop producers. While they can reduce local yields, widespread production losses often drive price increases. This study presents a panel approach that accounts for the price–yield correlation to assess the impact of such events on crop revenues, focusing on U.S. corn and soybeans.

Copula–entropy theory for multivariate stochastic modeling in water engineering

open access: yesGeoscience Letters, 2018
The copula–entropy theory combines the entropy theory and the copula theory. The entropy theory has been extensively applied to derive the most probable univariate distribution subject to specified constraints by applying the principle of maximum entropy.

NLP‐enabled automated assessment of scientific explanations: Towards eliminating linguistic discrimination

open access: yesBritish Journal of Educational Technology, EarlyView.
Abstract As use of artificial intelligence (AI) has increased, concerns about AI bias and discrimination have been growing. This paper discusses an application called PyrEval in which natural language processing (NLP) was used to automate assessment and provide feedback on middle school science writing without linguistic discrimination.

Unravelling the Impact of Ideological Diversity on Stock Returns Amidst Uncertainty

open access: yesFinancial Markets, Institutions &Instruments, EarlyView.
ABSTRACT Recently, the Covid‐19 uncertainties have raised interest in identifying factors that influence firms’ resilience. Existing Covid‐19 research primarily focused on market reactions and lockdown impacts, overlooking the influence of ideological diversity of firms’ directors on resilience. To address this gap, we examine personal contributions to

Alternative Approaches for Estimating Highest‐Density Regions

open access: yesInternational Statistical Review, EarlyView.
Summary Among the variety of statistical intervals, highest‐density regions (HDRs) stand out for their ability to effectively summarise a distribution or sample, unveiling its distinctive and salient features. An HDR represents the minimum size set that satisfies a certain probability coverage, and current methods for their computation require ...

A genetic algorithm simheuristic for solving the stochastic project portfolio selection problem with portfolio reliability constraints

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract In response to the increasing complexity of modern products, dynamic markets, and intensified competition, project‐based organizations are actively seeking methodologies to efficiently manage their expanding project portfolios. This paper analyzes the project portfolio selection problem in uncertain environments. Despite recent advances in the

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

open access: yesJournal of Anatomy, EarlyView.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Integrating Entropy and Copula Theories for Hydrologic Modeling and Analysis

open access: yesEntropy, 2015
Entropy is a measure of uncertainty and has been commonly used for various applications, including probability inferences in hydrology. Copula has been widely used for constructing joint distributions to model the dependence structure of multivariate ...
