When Aviation CSR Efforts Are Not Enough: How Do We Inspire Airline Passengers to Offset Their Travel Footprints?

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Voluntary carbon offsetting programs (VCOPs) are available for airline passengers who want to take action and offset their scope 3 emissions. Yet, their uptake is very limited. In this study, we propose an integrated theoretical model involving the norm activation theory and protection motivation theory to understand airline passengers ...

An Arnoldi Method for Nonlinear Eigenvalue Problems [PDF]

open access: yesBIT Numerical Mathematics, 2004
For the nonlinear eigenvalue problem T(lambda)x = 0 we propose an iterative projection method for computing a few eigenvalues close to a given parameter. The current search space is expanded by a generalization of the shift-and-invert Arnoldi method. The resulting projected eigenproblems of small dimension are solved by inverse iteration. The method is

CSR Disclosure Tone and Investor Signaling in IPO Prospectuses: A Textual Sentiment Analysis in U.S. Capital Markets

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines whether corporate social responsibility (CSR) disclosure in IPO prospectuses functions as a credible sustainability signal and how its credibility influences investor responses in U.S. capital markets. Drawing on a sample of 681 IPOs conducted between 2019 and 2023, we employ textual content analysis to construct a ...

Positive solutions and nonlinear multipoint conjugate eigenvalue problems

open access: yesElectronic Journal of Differential Equations, 1997
Values of $lambda$ are determined for which there exist solutions in a cone of the $n^{th}$ order nonlinear differential equation, $$u^{(n)} = lambda a(t) f(u),,quad 0 < t < 1,,$$ satisfying the multipoint boundary conditions, $$u^{(j)}(a_i) = 0,,quad ...

Structured pseudospectra for nonlinear eigenvalue problems [PDF]

open access: yes, 2008
In this paper we introduce structured pseudospectra for nonlinear eigenvalue problems and derive computable formulae. The results are applied to the sensitivity analysis of the eigenvalues of a second-order system arising from structural dynamics and of ...

A Novel Text‐Based Framework for Forecasting Carbon Prices

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This study proposes a text‐based framework for predicting EU carbon prices. Using weekly data from 2020 to 2024, we construct a multivariate dataset combining financial indicators, commodity prices, Google Trends measures, and news‐based sentiment extracted using FinBERT.

The Sector Liquidity Timing Ability of Bond Mutual Funds

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate whether bond mutual fund managers exhibit market liquidity timing skills in the U.S. corporate bond market. At the portfolio level, we find only weak evidence that bond funds adjust their overall market exposure in anticipation of changes in corporate bond market liquidity.

A Hardy Inequality with Remainder Terms in the Heisenberg Group and the Weighted Eigenvalue Problem

open access: yesJournal of Inequalities and Applications, 2007
Based on properties of vector fields, we prove Hardy inequalities with remainder terms in the Heisenberg group and a compact embedding in weighted Sobolev spaces. The best constants in Hardy inequalities are determined.
