When Collaboration Bridges or Breaks: A Systematic Review of Emerging Trends in Supply Chain Resilience and Sustainability

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Widespread digital adoption has challenged our understanding of how these tools reshape collaboration, trust and sustainability outcomes across different institutional and network contexts. As networks now pursue resilience and sustainable development in parallel, we map emerging research directions and identify how collaboration and ...

Investigating Streamless Sets [PDF]

open access: yes, 2015
In this paper we look at streamless sets, recently investigated by Coquand and Spiwack. A set is streamless if every stream over that set contain a duplicate.

Rank‐based estimation of propensity score weights via subclassification

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

A partial envelope approach for modelling multivariate spatial‐temporal data

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.

Classical consequences of constructive systems

open access: yes, 2023
This is a survey of formal axiomatic systems for the three main varieties of constructive analysis, in a common language and with intuitionistic logic, which are as nearly as possible compatible with classical analysis and with one another.

The Synthesis of Logic Programs from Inductive Proofs [PDF]

open access: yes, 1990
We describe a technique for synthesising logic (Prolog) programs from non-executable specifications. This technique is adapted from one for synthesising functional programs as total functions. Logic programs, on the other hand, define predicates.

What Do We Know About How Companies Manage Waste? The Effect of Tenure and Diversity of Directors on Disclosures

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper aims to analyze the effect of board tenure on firms' waste management disclosure and explore whether this effect is amplified by board gender and cultural diversity. The analysis is based on data from 832 large firms worldwide from 2011 to 2020.

Behavioral economics: science or exoticism?

open access: yesМир новой экономики, 2018
While studying economics as a science and an active sphere of human activity, scientists aim to give consistency to their knowledge, ensure that they are adequate and constructive.
