Cluster Analysis of Circular Economy and Industrial Symbiosis Practices and Their Impact on Sustainability Performance in the Plastics Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...

Eigenvalues assignment in uncontrollable linear systems

open access: yesBulletin of the Polish Academy of Sciences Technical Sciences, 2022
It is shown that in uncontrollable linear system ẋ = Ax + Bu it is possible to assign arbitrarily the eigenvalues of the closed-loop system with state feedbacks u = Kx, K ∈ ℜn⨉m if rank [A B] = n. The design procedure consists in two steps. In the step 1 a nonsingular matrix  M ∈ ℜn⨉m is chosen so that the pair (MA,MB) is controllable. In step

Remarks on the Cayley Representation of Orthogonal Matrices and on Perturbing the Diagonal of a Matrix to Make it Invertible [PDF]

open access: yes, 2013
This note contains two remarks. The first remark concerns the extension of the well-known Cayley representation of rotation matrices by skew symmetric matrices to rotation matrices admitting -1 as an eigenvalue and then to all orthogonal matrices.

Controlling for individual heterogeneity in longitudinal models, with applications to student achievement

open access: yes, 2007
Longitudinal data tracking repeated measurements on individuals are highly valued for research because they offer controls for unmeasured individual heterogeneity that might otherwise bias results.

Supply Chain Network, ESG Scores and Financial Performance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper provides novel evidence on the role of supply chain networks in influencing firms' environmental, social and governance (ESG) scores and financial performance. Our analysis employs financial, board, ESG and supply chain data, resulting in an unbalanced panel of over 16,000 firm‐year observations from 3028 publicly traded US firms ...

Aggregating distributed energy resources for grid flexibility services: A distributed game theoretic approach

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Eigenvalue Placement and Stabilization by Constrained Optimization [PDF]

open access: yes, 1985
A pole placement algorithm is proposed which uses constrained nonlinear optimization techniques on a finite dimensional model of a linear n degree of freedom system. Low order feedback control is assumed where r poles may be assigned; r being the rank of

Measuring Consumer Aversion Toward AI in Marketing Communication and Assessing Its Relationship to Brand Perceptions and Purchase Intention

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT Some consumers exhibit aversion toward artificial intelligence (AI), particularly when it is embedded in persuasive marketing communication (MarCom). Here, we developed and validated a measure of consumer aversion to AI in MarCom and examined its downstream consequences for brand perceptions and purchase intention.

Stability robustness improvement of direct eigenspace assignment based feedback systems using singular value sensitivities [PDF]

open access: yes
A methodology to improve the stability robustness of feedback control systems designed using direct eigenspace assignment techniques is presented. The method consists of considering the sensitivity of the minimum singular value of the return difference ...

Hydrogen Atom Transfer: An Intramolecular Main‐Group Metal‐Ligand Cooperative Biradical Pathway

open access: yesChinese Journal of Chemistry, EarlyView.
The molecular system consisting of a main‐group metal and a redox‐active ligand, ((2,6‐iPr2C6H3)NC(Me))2AlCl(THF), has been shown to react with azides and diazomethanes, yielding products through both a biradical intermediate and a hydrogen atom transfer process.
