Lost in aggregation? On the importance of local food price data for food poverty estimates
American Journal of Agricultural Economics, EarlyView.Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

American Journal of Agricultural Economics, EarlyView.Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

American Journal of Botany, EarlyView.Abstract Premise The optimal timing of reproduction depends on the relative risk and benefit of continued growth. These risks and benefits depend on the local environment, which varies seasonally. While temperature and water availability are well‐studied selective agents on reproductive timing, less is known about other seasonally variable factors ...

Foliar salt spray exclusion and tissue tolerance underlie local adaptation to oceanic salt spray
American Journal of Botany, EarlyView.Abstract Premise Surviving the effects of oceanic salt spray is critical for plants in coastal ecosystems, yet the mechanisms of coastal plant resilience to salt spray are not well understood. We investigated mechanisms of salt spray adaptation by comparing five latitudinal pairs of yellow monkeyflower accessions locally adapted to coastal and inland ...

Model error space and data assimilation in the Mediterranean Sea and nested models
, 2007 In this work, we implemented the GHER hydrodynamic model in the Gulf of Lions (resolution 1/100 °). This model is nested interactively in another model covering the North-Western basin of the Mediterranean Sea (resolution 1/20°), itself nested in a model covering the whole basin (1/4 °).

American Journal of Community Psychology, EarlyView.Abstract The current study seeks to explore the reciprocal associations between mentor–mentee relationship strength and relationships with parents and peers across 2 years of mentoring. It is a secondary analysis of data collected by a national mentoring organization from youth (N = 1368; M age = 11.5 years; 59% female; White [n = 629], 30% Black [n ...
