Obligation, Exemption and Remission: The Multi‐Layered Functioning of the Poll Tax (Cizye) in Ottoman Governance during the Long Eighteenth Century

History, EarlyView.
Abstract This article examines the poll tax (Ottoman Turkish cizye; Arabic jizya) levied on non‐Muslim subjects of the Ottoman Empire, not as a fixed, one‐dimensional tax item within the Ottoman fiscal system but as a multi‐layered administrative instrument organized around obligation, exemption and remission.

Lunar Trailblazer Spacecraft Tracking and Mission Recovery Attempt: Characterization of Status and Behavior of a Non‐Cooperative Object in Cis‐Lunar Space

Earth and Space Science
Unexpectedly following launch, the Lunar Trailblazer mission experienced software anomalies that led it to orient solar panels away from the sun and lose communication with Earth. This paper describes efforts to determine the spacecraft state and attempt

The Momentum of ‘Developed’: Bodies of Water, Aging Bodies and Malta's Interventions at the UN

History, EarlyView.
Abstract Histories of major powers continue to shape how many scholars conceptualize internationalism. By focusing on Malta's interventions at the UN challenges, this article challenges such narrative. In particular, it examines Arvid Pardo's 1967 petition that the seabed be reconceived and protected as the ‘common heritage of mankind’ and Vincent ...

STRATIFIED ADAPTATION: Infrastructure, Elevation, and Cascading Floods in the Urban Mekong Delta

International Journal of Urban and Regional Research, EarlyView.
Abstract Flood‐prone cities in the global South are increasingly the target of infrastructure projects aimed at building climate ‘resilience’. At the same time, residents of these cities take adaptation to flooding into their own hands. In this article we examine the interrelationship between household‐scale and urban‐scale flood mitigation projects in

Strategies and prospects for energy storage in future lunar base

Advances in Mechanical Engineering
Lunar energy storage systems face critical challenges from extreme thermal cycling (−173°C to 127°C) and prolonged darkness periods (354-hour nights). This study systematically evaluates three categories of lunar-compatible technologies: Electrochemical ...

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions

Integrative Zoology, EarlyView.
For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

The temporal environmental correlates of spotted hyena (Crocuta crocuta) encounters with livestock enclosures: Insights from central Kenya

Conservation Science and Practice, EarlyView.
We studied spotted hyena (Crocuta crocuta) encounters with livestock enclosures, an important but understudied stage of the livestock depredation process. Using camera traps, we examined how encounter probability and timing varied with rainfall, moonlight, and temperature. Our findings deepen our understanding of hyena behavior around livestock and may

We Don't Settle: Decolonizing the Heritage Sector by Empowering Young People of Color

Curator: The Museum Journal, EarlyView.
ABSTRACT Decolonizing the heritage sector has taken center stage since the murder of George Floyd and the subsequent Black Lives Matter protests. There have been efforts for decades to make the sector address institutional racism and be more inclusive to racialized minorities.
