Generation of entropy in spark ignition engines

, 2007
Recent engine development has focused mainly on the improvement of engine efficiency and output emissions. The improvements in efficiency are being made by friction reduction, combustion improvement and thermodynamic cycle modification. New technologies such as Variable Valve Timing (VVT) or Variable Compression Ratio (VCR) are important for the latter.

Corruption Control and Corporate Hazardous Waste Emissions: Cross‐Country Evidence and the Moderating Role of Agenda 2030

Business Strategy and the Environment, EarlyView.
ABSTRACT The aim of this study is to examine the impact of corruption control, as a public institutional mechanism, on hazardous waste emissions of private sector entities. We also examine the extent to which Agenda 2030 moderates the relationship. We analyse data from the top 500 global companies.

The Grey Zone of Stakeholder Engagement: Misalignment as a Manifestation of Greyness in Stakeholder Collaboration

Business Strategy and the Environment, EarlyView.
ABSTRACT This study identifies and conceptualises the grey zone of stakeholder engagement and explores how it manifests in a collaborative context related to the promotion of a circular economy. While prior research on stakeholder engagement has highlighted the positive, value‐creating bright side or the harmful dark side of stakeholder engagement, we ...

Decoding the Circular Economy Job Market in the EU: A Quantitative and Comparative Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT The circular economy (CE) is increasingly promoted as a pathway to sustainable development, yet systematic evidence on the structure of the CE labor market remains limited. Little is known about how CE‐related job opportunities are distributed across countries, which job characteristics dominate this market, and how such patterns compare with ...
