Oxygen Abundances in Two Metal-Poor Subgiants from the Analysis of the 6300 A Forbidden O I Line

open access: yes, 1999
Recent LTE analyses (Israelian et al. 1998 and Bosegaard et al. 1999) of the OH bands in the optical-ultraviolet spectra of nearby metal-poor subdwarfs indicate that oxygen abundances are generally higher than those previously determined.

CEO Overconfidence and Corporate Social Responsibility: A Micro‐CSR Perspective

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Although research on micro‐level CSR has increasingly emphasized individual‐level antecedents, the role of CEO overconfidence has not been systematically integrated into the literature. To address this gap, a systematic literature review was undertaken of 62 studies on CEO overconfidence and CSR, revealing a mixed picture of positive, negative,

Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Does a More Functionally Diverse Top Management Team Make the Financial Statements More Comparable?

open access: yesJournal of Corporate Accounting &Finance, EarlyView.
ABSTRACT We examine whether top management team (TMT) functional diversity affects financial statement comparability. Drawing upon upper echelons theory and the information sharing perspective in diversity research, we argue that TMT functional diversity produces more comparable financial statements due to better information sharing and integration ...
