International Statistical Review, EarlyView.Summary Defining a ‘hat‐matrix’ for a model is essential in many model diagnostic procedures, as it acts as an orthogonal projector from the observation space to the model space. In this paper, we introduce a unique Hat‐matrix for the class of hierarchical generalised linear models (HGLMs), which includes, as a special case, the subclass of generalised

Multi‐objective maritime vessel routing with safety considerations
International Transactions in Operational Research, EarlyView.Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

A spectral analysis extension to DEMATEL for strategic leverage points identification
International Transactions in Operational Research, EarlyView.Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

Journal of Management Studies, EarlyView.Abstract Can institutional logics be damaging for the same category of actors they are presumed to benefit? Can firms prevent or reduce this detrimental effect? This study integrates the institutional logics perspective with category research to examine these questions in the context of community banks.

ON THE INVERSE EIGENVALUE PROBLEM OF A EULER BERNOULLI BEAM UNDER DISTRIBUTED LOADS
Academy Journal of Science and EngineeringThe problem of posing and solving an inverse eigenvalue problem of a Euler Bernoulli steel beam under distributed loads is studied in this paper. The governing equations are tackled using finite Fourier Sine transform for the simple support end condition

Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary By integrating artificial intelligence (AI) platforms into their processes, firms aim to enhance their strategic capabilities and gain a competitive advantage. This study investigates the impact of such platforms on value generation within solution‐based strategies, proposing two connected mechanisms.
