Algebra and technology: Emerging issues [PDF]

open access: yes, 2001
Although there are a number of technologies related to school algebra, it is only the personal technology of the graphics calculator that seems likely to be available widely enough to influence curriculum design and implementation on a large scale.

Nonprofit Governance and Financial Stability: A Study of Government‐Funded Social Services

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT Nonprofit social service providers are essential in delivering vital services, often with public funding. This study adopts a contingency perspective to explore the relationship between organizational governance and financial stability in publicly funded nonprofit organizations. We use a combination of comparative multilevel analysis (CMA) and

CSRcalculator: A reproducible framework for understanding plant ecological strategies

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants respond to environmental change is essential for conserving biodiversity and managing ecosystems under climate change. We developed CSRcalculator, an open‐source platform that brings together major competitor, stress‐tolerator, ruderal (CSR) models to make ecological strategy classification accessible, reproducible and scalable.

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

open access: yesResponsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Unified Treatment of a Class of Spherically Symmetric Potentials: Quasi-Exact Solution

open access: yesAdvances in High Energy Physics, 2016
We investigate the Schrödinger equation for a class of spherically symmetric potentials in a simple and unified manner using the Lie algebraic approach within the framework of quasi-exact solvability.

High‐Speed Rail and Spatial Equity: Unpacking the Sustainability Paradox of Land Use and Fiscal Pressure in County‐Level Cities

open access: yesSustainable Development, EarlyView.
ABSTRACT Infrastructure‐led development in rapidly urbanizing economies often generates accessibility gains that fail to translate into balanced urban outcomes, particularly when local fiscal institutions redirect those gains toward revenue‐generating land uses. Filling this gap, especially in fiscally constrained county‐level cities where land finance

Koszul homomorphisms and universal resolutions in local algebra

open access: yesForum of Mathematics, Sigma
We define a local homomorphism $(Q,k)\to (R,\ell )$ to be Koszul if its derived fiber $R\otimes ^{\mathsf {L}}_Q k$ is formal, and if $\operatorname {Tor}^{Q}(R,k)$ is Koszul in the classical sense.

The Mitigating Role of Managerial Ability in ESG Decoupling

open access: yesSustainable Development, EarlyView.
ABSTRACT Does managerial competence widen or bridge the gap between environmental, social, and governance (ESG) disclosures and actual performance? This paper explores the relationship between CEO ability and corporate decoupling regarding sustainability issues.
