Characteristics, Motivators, and Enablers of Educators Who Earn Many Micro‐Credentials
Future in Educational Research, EarlyView.ABSTRACT This study explores the characteristics, motivators, and enablers of US educators, who earned more than ten micro‐credentials. Although research exists on attitudes and motivators associated with educators newly engaging with micro‐credentials, it lacks insights into learners earning many micro‐credentials.

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver
International Journal for Numerical Methods in Fluids, EarlyView.A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Numerical enclosure for each eigenvalue in generalized eigenvalue problem
Journal of Computational and Applied Mathematics, 2012 The paper presents an algorithm for enclosing all eigenvalues in the generalized eigenvalue problem \[ Ax=\lambda Bx,\;A,B\in {\mathbb C}^{n\times n},\;\lambda\in{\mathbb C},\;x\in{\mathbb C}^n\tag{1} \] where \(\lambda\) is the eigenvalue and \(x\neq 0\) is an eigenvector corresponding to \(\lambda.\) This algorithm is applicable even if \(A\in ...

A Deep Learning Framework for Forecasting Medium‐Term Covariance in Multiasset Portfolios
Journal of Forecasting, EarlyView.ABSTRACT Forecasting the covariance matrix of asset returns is central to portfolio construction, risk management, and asset pricing. However, most existing models struggle at medium‐term horizons, several weeks to months, where shifting market regimes and slower dynamics prevail.

International 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

Love of the Job: What It Is, How to Measure It, and Why It Matters for Work Outcomes
Human Resource Management, EarlyView.ABSTRACT Employee retention, motivation, performance, and well‐being remain enduring priorities in human resource management, yet existing constructs such as engagement, commitment, and satisfaction do not fully capture the depth of emotional attachment that some employees feel towards their jobs.

Evolutionary dynamics on a regular networked structured and unstructured multi‐population
International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.
