Farm labor scarcity and its uneven impacts on crop producers in the United States

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Open space for a new urbanity

open access: yes, 2009
'Open space' is a term used to qualify all unbuilt spaces with rural and natural characteristics, located within large urban areas. Although this expression is being abandoned in North America, it is getting growing interest in Europe. This tendency comes from difficulties in identifying the great diversity of unbuilt spaces, but also from the fact ...

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Internet use and adolescent development: A conceptual model integrating behavioral and contextual theories

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract In the digital era, adolescent development is deeply embedded in the cyber environment. Despite ongoing debate on the benefits and/or risks that Internet use brings to adolescents in empirical studies, conceptual and theoretical discussion on the influences of the intensity and modalities of Internet use is peripheral.

An X‑Shaped Chiral Non‑Fullerene n‐Type Semiconductor: Application in Perovskite Solar Cells and Chirality‑Induced Spin Selectivity

open access: yesAngewandte Chemie, EarlyView.
A highly electron‑accepting derivative of cyclobisbiphenylenecarbonyl (CBBC‐TIC) is reported. CBBC‐TIC functions as an electron‐transport layer for perovskite solar cells, achieving a power conversion efficiency of 20.6%. Furthermore, the enantiomers of CBBC‐TIC exhibited spin‐selective electron transport with high enantiospecific magnetic conductance ...
