Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Advancing Theory and Practice Concerning CO2e Emissions: A Time‐Based Tool for Organisations

Business Strategy and the Environment, EarlyView.
ABSTRACT Although organisations are increasingly scrutinised on their CO2e emissions, economic growth is frequently encouraged. Eco‐efficiency–based initiatives—‘doing more with less’—could be a solution. The problem is that many organisations (e.g., smaller enterprises without access to specialist knowledge) have difficulties in gauging the impact of ...

Hydraulic analysis of a compound weir (triangular-rectangular) simulated with computational fluid dynamics (CFD)

Tecnología y ciencias del agua, 2021
To make an efficient delivery of water to irrigation users, it is necessary to have accurate dispositive to measure flow rates. These dispositive include triangular and rectangular weirs for measured flow rates ranges between 30 and 200 l s-1.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

CEO Characteristics and CSR Governance Quality: Evidence From Europe

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Leveraging a sample of European listed firms, we investigate whether CEO duality, CEO tenure, and CEO membership in the CSR board committee are associated with the quality of corporate social responsibility (CSR) governance. Our findings indicate that CEO duality is negatively associated with CSR governance quality, whereas CEO membership on ...
