Socioeconomic status, parenting factors and academic achievement among Chinese adolescents aged 12–13: How do they relate?

British Educational Research Journal, EarlyView.
Abstract Extensive research has shown that students from higher socioeconomic status (SES) backgrounds generally outperform their lower SES peers. Nevertheless, some low SES students succeed, albeit it ‘against the odds.’ Coleman's (1988) theory of social capital in the family suggests that financial capital, human capital and social capital all affect

Global phase portraits of quadratic systems with a complex ellipse as invariant algebraic curve

, 2021
In this paper we study a new class of quadratic systems and classify all its phase portraits. More precisely, we characterize the class of all quadratic polynomial differential systems in the plane having a complex ellipse x^2 y^2 1=0 as invariant ...

Stakeholder Engagement as a Design Principle: Orchestrating a Digital Platform for the Safety and Sustainability of the Nanomaterials Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The governance of chemicals and nanomaterials presents a critical challenge, as significant uncertainties regarding safety and sustainability match their innovation potential. This creates a “knowledge‐to‐action” gap, hindering the practical implementation of safety and sustainability by design (SSbD) principles.
