Business Strategy and the Environment, EarlyView.ABSTRACT Building upon the upper echelons theory, this study investigates the effects of CEO characteristics—in terms of age, gender, and human capital (legal background, educational level, and industry expertise)—on CSR reporting assurance. Using a combination of GMM and logistic regression, it analyzes a sample of non‐financial Italian publicly ...

The conical K\"ahler-Ricci flow on Fano manifolds [PDF]
, 2015 In this paper, we study the long-term behavior of the conical K\"ahler-Ricci flow on Fano manifold $M$. First, based on our work of locally uniform regularity for the twisted K\"ahler-Ricci flows, we obtain a long-time solution to the conical K\"ahler ...

RICCI LOWER BOUND FOR KÄHLER–RICCI FLOW [PDF]
Communications in Contemporary Mathematics, 2014 We provide general discussion on the lower bound of Ricci curvature along Kähler–Ricci flows over closed manifolds. The main result is the non-existence of Ricci lower bound for flows with finite time singularities and non-collapsed global volume. As an application, we give examples showing that positivity of Ricci curvature would not be preserved by ...

From the Ricci flow evolution equation to vanishing theorems for Ricci solitons [PDF]
arXiv, 2020 In the paper, we study evolution equations of the scalar and Ricci curvatures under the Hamilton's Ricci flow on a closed manifold and on a complete noncompact manifold. In particular, we study conditions when the Ricci flow is trivial and the Ricci soliton is Ricci flat or Einstein.

European Journal of Organic Chemistry, Accepted Article.The growing interest towards biopolymers application in amphiphilic conditions prompted us to explore the preparation of fluorinated cellulosic materials. Cellulose (CE) and carboxymethylcellulose (CMC) were functionalized with highly fluorinated pendants, through a nucleophilic aromatic substitution on 3‐pentadecafluoroheptyl‐5‐pentafluorophenyl‐1,2,4‐

Forecasting Digital Asset Return: An Application of Machine Learning Model
International Journal of Finance &Economics, EarlyView.ABSTRACT In this study, we aim to identify the machine learning model that can overcome the limitations of traditional statistical modelling techniques in forecasting Bitcoin prices. Also, we outline the necessary conditions that make the model suitable.

International Journal of Finance &Economics, EarlyView.ABSTRACT Banks within the MENA regions serve as pivotal agents in fostering economic growth through extensive lending to businesses, individuals and corporations, thereby amplifying employment within the banking sector. A pressing concern affecting these banks is the proliferation of NPLs, which not only diminishes net earnings but also escalates ...
