Green Budgeting in South Korea: Issue Ownership and Ministerial Leadership

Public Administration Review, EarlyView.
ABSTRACT As climate governance gains urgency, green budgeting has emerged as a vital policy tool to align fiscal systems with environmental goals. Yet, institutional and leadership factors shaping its success remain underexplored. This study examines how issue ownership and ministerial leadership jointly influence green budgeting outcomes in South ...

Two-dimensional multi-beam steering for parallel free-space optical communication based on a silicon nitride optical phase array

APL Photonics
We propose and demonstrate a broadband two-dimensional multi-beam optical phased array (MOPA) with four beams based on a Butler matrix on a silicon nitride (Si3N4) platform. A beamforming network utilizing cascaded Butler matrix splitting arrays has been

Drivers of planted seedling survival and growth in a Mediterranean‐climate woodland restoration experiment

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of degraded ecosystems is an important means of promoting and conserving biodiversity. However, restoration projects on average fail to reach target biodiversity levels within the time frames they are studied. Competition from non‐native groundlayer grasses and forbs, potential facilitative effects of plant–plant ...

Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

Restoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

The Politics of Social Care in Japan: How Central–Local Interactions Shaped Child Allowances and Elderly Medical Care

Social Policy &Administration, EarlyView.
ABSTRACT This study examines why Japan's social care reforms of the early 1970s led to a generous elderly care system but only modest and narrowly targeted support for children. Although child allowances and free medical care for the elderly were introduced almost simultaneously, they followed sharply divergent paths.
