First disk-resolved spectroscopy of (4) Vesta

, 2009
Vesta, the second largest Main Belt asteroid, will be the first to be explored in 2011 by NASA's Dawn mission. It is a dry, likely differentiated body with spectrum suggesting that is has been resurfaced by basaltic lava flows, not too different from the

Adapting to Changing Rainfall and Developing Off‐Farm Employment: Implications for the Adoption of Direct Seeding in Rice Production

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Rice is the main staple food for more than half of the world's population and the income from rice is an essential source for livelihoods of millions of households. We examine whether direct seed in rice production is an adaptation of rice farmers to rainfall changes and farm labor scarcity.

Temperature Sensitivity and Adaptation of Cereal Yields: Empirical Evidence From Italy

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper investigates the evolving temperature sensitivity and climate adaptation of cereal yields in Italy from 1952 to 2023, using province‐level data for maize, common wheat, and durum wheat. Employing panel data econometric methods, we estimate yield responses to heat exposure, changes in sensitivity over time, and adaptation to climate ...

The Sediments in the Beibu Gulf Reveal Dramatic Paleoenvironmental Changes and Climate Events over the Past ~20,000 Years

Journal of Marine Science and Engineering
The geochemical characteristics of a 2.1 m BBW25 core, collected from the Beibu Gulf, have been investigated in terms of the major and trace elements, organic matter, and CaCO3 and AMS 14C dating by XRF, ICP-OES, ICP-MS, and more.

Why Didn't I Get a Payout? Understanding Farmer Choices, Index Insurance, and Basis Risk

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Index insurance, while heralded as a potential solution to alleviate poverty and food insecurity among agricultural households, has its own set of challenges, notably basis risk. Basis risk is the discrepancy between the insurance payout and losses incurred, posing a significant deterrent to the adoption of index insurance.

Intense Embodiment and Women’s ‘Weather Work’ in Motorcycling

Cultural Studies ↔ Critical Methodologies
This article aims to develop the underexamined lived experiences of ‘weather work’ via the motorcycling ‘weather world’, addressing the embodied and sensorial learning ways of knowing. Drawing on a phenomenologically inspired approach, I explore the haptic senses of heat and cold via heightening understandings of weather work, aiming to provide key ...

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...

Integration of Geochemical and Geophysical Data to Characterize and Map Lateritic Regolith: An Example in the Brazilian Amazon

Geochemistry, Geophysics, Geosystems, 2018
In tropical regions like the Amazon, there are extensive lateritic covers that have not been properly mapped, despite their economic‐bearing minerals and their importance related to denudation and regolith landscape studies.
