Ultracool Subdwarfs: Metal-poor Stars and Brown Dwarfs Extending into the Late-type M, L and T Dwarf Regimes

open access: yes, 2004
Recent discoveries from red optical proper motion and wide-field near-infrared surveys have uncovered a new population of ultracool subdwarfs -- metal-poor stars and brown dwarfs extending into the late-type M, L and possibly T spectral classes. These objects are among the first low-mass stars and brown dwarfs formed in the Galaxy, and are valuable ...

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Goal Displacement and Goal Conflicts in Circular Innovation Initiatives: Types and Mitigation Practices

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Many firms set ambitious sustainability goals but these are frequently “displaced” by proxy goals that are easier to track and measure. However, the specific types of goal conflicts that follow from this displacement are poorly understood. We conducted a case study of circular innovation initiatives at a global MedTech company and identified ...

Reporting What Matters, or Reporting What Looks Good? Materiality and Balance in Post–Rana Plaza Apparel Sustainability Disclosure

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Sustainability reports (SRs) are widely criticized for vague disclosures and selective emphasis on positive outcomes, yet systematic research on two core SR challenges remains limited: materiality (whether disclosed content is relevant) and balance (whether both achievements and challenges are reported).

A Possible Correlation between Metallicity and Near-IR Color for Late-M and L Dwarfs

open access: yesThe Astrophysical Journal
We examine the relationship between metallicity and J − K color for 64 benchmark late-M and L dwarfs, all of which are wide companions to higher-mass stars, and six of which are new discoveries.

A magnetic study of spotted UV Ceti flare stars and related late-type dwarfs

open access: yesThe Astrophysical Journal, 1980
A multichannel photoelectric Zeeman analyzer has been used to investigate the magnetic nature of the spotted UV Ceti flare stars. Magnetic observations were obtained on a sample of 19 program objects, of which 5 were currently spotted dKe-dMe stars, 7 were normal dK-dM stars, 7 were UV Ceti flare stars, and 1 was a possible post-T Tauri star.

Sustainable Development Goals' Discourse in the Accounting and Business Literature: A Rhetorical Lens

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The role of academia in shaping the Sustainable Development Goals (SDGs) remains insufficiently understood. This study examines how SDG discourse is constructed within accounting and business research by integrating bibliometric analysis with a systematic review of 731 peer‐reviewed articles published between 2020 and 2024.

Market and Nonmarket Strategies in Focus: How Entrepreneurs Tackling the Grand Challenge of Waste Management Navigate Institutional and Market Adversity in Ghana

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Waste management remains a critical grand challenge in African countries. While entrepreneurship has been a viable strategy for addressing this challenge, it is fraught with constraints. This study investigates the strategies orchestrated by entrepreneurs to navigate adversity in Waste management and ensure the social and economic viability of
