Circular Innovations in Complex Systems: A Blueprint of Four Design Archetypes

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular innovations (CI), defined as the redesign of products, services or practices to minimise waste, reduce resource use and regenerate natural systems, are essential for advancing the circular economy. Despite growing recognition, their deployment in systems of linked parts with unpredictable interactions (complex systems) remains limited

Rotation of the Mass Donors in High-mass X-ray Binaries and Symbiotic Stars

Acta Polytechnica CTU Proceedings, 2015
Our aim is to investigate the tidal interaction in High-mass X-ray Binaries and Symbiotic stars in order to determine in which objects the rotation of the mass donors is synchronized or pseudosynchronized with the orbital motion of the compact companion.

Environmental Sustainability, Health and Social Wellbeing and Agility in Industry 4.0 to Society 5.0 Transition

Business Strategy and the Environment, EarlyView.
ABSTRACT Industry 4.0 is pushing the triple bottom line toward a necessary evolution: Society 5.0. Achieving this agile future depends on environmental sustainability, health and social wellbeing (H&SW). Therefore, this study,examines how environmental, social and governance (ESG) strategies operationalise the psychological, social and physical ...

The Impact of Wind Accretion in Evolving Symbiotic Systems

The Astrophysical Journal
We investigate the impact of geometric corrections to the Bondi–Hoyle–Lyttleton (BHL) accretion scheme applied to evolving symbiotic systems. We model systems where 0.7 and 1 M _⊙ white dwarfs (WDs) accrete material from solar-like stars with initial ...

Advancing Circular Economy Measurement in Agri‐Food: An Updated Dashboard of Indicators

Business Strategy and the Environment, EarlyView.
ABSTRACT The increasing relevance of the circular economy in the agri‐food sector highlights the need for systematic tools to assess environmental, economic and social performance. Despite the proliferation of studies, literature still presents fragmentation and lacks comprehensive sets of indicators across certain thematic areas.

Exploring the Long-term Temporal Variability in Polarization through Multiepoch Optical Spectropolarimetry. II. A Sample of Symbiotic and Red Giant Stars

The Astronomical Journal
Measuring polarization and its temporal variability in the continuum and across emission features provides a powerful probe of the small-scale circumstellar environments of astrophysical sources, on spatial scales otherwise inaccessible to direct imaging

Mass Transfer in Mira-Type Binaries

Open Astronomy, 2012
Detached, symbiotic binaries are generally assumed to interact via Bondi-Hoyle-Littleton (BHL) wind accretion. However, the accretion rates and outflow geometries that result from this mass-transfer mechanism cannot adequately explain the observations of

Supersoft sources inXMM-NewtonSmall Magellanic Cloud fields [PDF]

Astronomy & Astrophysics, 2006
We report the detection and study of two faint ROSAT supersoft X-ray sources in the SMC field withXMM-Newton, RX J0059.1−7505 and RX J0059.4−7118. Due to the larger eff ective area ofXMM-Newton we can constrain the X-ray spectra of both sources. RX J0059.1−7505 is optically identified with the symbiotic LIN 358 in the SMC.

Beyond Participation: A Multitheoretical Framework for Stakeholder Relationship Management in Circular Economy Initiatives

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Circular economy (CE) initiatives require coordination among stakeholders whose roles, resources, and interests are often unevenly distributed across value networks. Existing CSR, ESG, and stakeholder engagement frameworks offer useful starting points, but they do not fully explain how these relationships are governed during circular ...
