Unraveling The Connectedness Between Non-Fungible Tokens, Decentralized Finance, And Green Assets During Turbulent Times, Rija Anwar, Syed Ali Raza

Business Review

Green assets during the Bitcoin plummet-2018, COVID-2019, worldwide decline in oil demand-2020, and the Russia-Ukraine Conflict. The quantile connectedness approach, combined with the extreme tail of distribution technique (Ando et al., 2021), has been employed. According to static quantile connectedness, NFTs and DeFi assets perform the role of spillover transmitters; in contrast, green assets receive spillovers across three distinctive market settings. Additionally, the dynamic time-varying net directional connectedness estimates reveal that during normal market condition, the connectedness degree between NFTs, DeFi assets, and green assets remains low relative to extreme events at different point in time. Moreover, it provides valuable …

The Push-Pull Model's Function In Understanding Public Sector Workers' Inter-Organisational Labour Mobility: The Views Of The Herzberg Two-Factor Theory, Rosemary Selestine Massae

Business Management Review

In the modern world, one of the challenges managers have in maintaining their talented staff is labour mobility. Inter-organisational labour mobility (ILM) has been found to be significantly influenced by co-worker relationships, work-family conflict, monetary compensation, and training and development. The pull-push paradigm was inspired by human migration. Since migration not only symbolises movement across physical locations but also encompasses other routine duties, theory is essential to comprehending ILM.

Consistency-Based Computing Of Fuzzy Eigenvalues And Fuzzy Eigenvectors: Method And Application, Kamala. R. Aliyeva Prof., Nihad Mehdiyev, Shamil Mehdi

Chemical Technology, Control and Management

The computation of eigenvalues and eigenvectors under uncertainty is a fundamental problem in fuzzy linear algebra and decision analysis. When matrix elements are represented by fuzzy numbers, classical spectral methods cannot be directly applied due to nonlinearity, ambiguity in ordering, and the propagation of uncertainty. Moreover, in many practical applications, particularly those involving pairwise comparison matrices, the reliability of eigenvalue-based results strongly depends on the consistency of the underlying data. This paper proposes a consistency-based framework for computing fuzzy eigenvalues and fuzzy eigenvectors that explicitly integrates consistency analysis into the spectral derivation process. The proposed method preserves the fuzzy structure …
