Modified F‐tests for assessing tree radial growth under linear‐circular regression models with correlated errors: A comprehensive toolbox rooted in G. E. P. Box's theorems

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Annual tree growth is a complex biological process. Modelling radial growth in the trunk by linear‐circular regression with one mode and correlated errors has allowed the definition and assessment of a preferred direction for 1 and 2 years. Here, modified F$$ F $$‐tests are presented for 3 years, 1 mode/year; 1 year, 2 modes for possible main ...

Mapping Corporate Environment, Social, and Governance Discourses: Analysis of Korean Companies' Sustainability Reports (2014–2024)

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporations increasingly use Environmental, Social, and Governance (ESG) reports to articulate their commitments, priorities, and performance in sustainability governance. This study examines how Korean firms have configured and reconfigured their sustainability discourses across industries and time using 634 sustainability reports (2014–2024)

CEO Age and Corporate Environmental Performance: Evidence From French Listed Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates the impact of CEO age on corporate environmental performance in the case of France, a country characterized by a strong commitment to sustainable development, emphasis on gender diversity, and elitism in the selection of corporate leaders. Using a sample of French firms listed on Euronext Paris between 2006 and 2024, we

Regeneration failure, fire, topography, and climate interact to drive temperate wet forest landscapes into fire traps

open access: yesEcography, EarlyView.
Where early successional forests are more flammable than old‐growth forests, forested landscapes are vulnerable to shifting into ‘fire traps' through positive feedbacks, where fire leads to more fire. These feedbacks are amplified by increased flammability driven by climate change, the presence of non‐native flammable plant species, and slowed ...

Combining paleoecology and modeling to explore cascading disturbances in forest ecosystems

open access: yesEcography, EarlyView.
Climate‐induced cascading disturbance interactions pose a major challenge to the sustainable provision of forest ecosystem services to society. Developing a deeper understanding and enhanced capacity to simulate these interactions is essential for identifying disturbance‐induced tipping points in forest ecosystems, and for improving management in ...

Lattice‐Strained Cu2O‐Ni/NiO Heterostructure Enables Selective Electrocatalytic C–C Coupling of Alcohols to Cinnamaldehyde in Aqueous Medium

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved the selective oxidation C–C coupling of PhCH2OH with EtOH to form cinnamaldehyde (CAL) on a designed Cu2O‐Ni/NiO heterojunction catalyst. By employing a salt precipitation strategy to balance the pH and cation concentration, an 86% conversion rate of PhCH2OH and a 67% high selectivity for CAL were realized.

The thickness of bark and bark per dm² of Cinchona.

open access: yesNetherlands Journal of Agricultural Science, 1953
An analysis of yielding capacity in stands of C. ledgeriana at Buitenzorg, Java, revealed a low correlation (r = +0.208) between bark thickness and yield of dry bark per tree. Relationship between amount of dry bark per dm.2 and bark thickness showed variability, both from clone to clone and within each clone.

Nested Institutions and Overlapping Mandates: A Policy Analysis of Mangrove Governance in Ghana, Tanzania Mainland, and Zanzibar

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Mangroves are critical resources in sustaining coastal communities by providing essential ecosystem goods and services. Occurring within the interface of land and sea, they serve as critical ecological zones shaped by dynamic interactions between terrestrial and marine systems.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...
