Replication Data for: Cities as Lobbyists

Hye Young You & Rebecca Goldstein
Individual cities are active interest groups in lobbying the federal government, and yet the dynamics of this intergovernmental lobbying are poorly understood. We argue that preference incongruence between city and its parent state government leads to under-provision of public goods, and cities need to appeal to the federal government for additional resources. We provide evidence for this theory using a dataset of over 13,800 lobbying disclosures filed by cities with populations over 25,000 between 1999...

CCAFS Gender Survey – Northern Uganda

CIAT & IFPRI
The purpose of this survey is to gather gender-disaggregated data on agricultural activities, decision-making, weather information, risk-perception and values from rural households. In Phase 2, the gender survey was adapted and implemented in other sites. It was adapted to include some of the production information from IMPACT-Lite since that survey has not been implemented in the new sites. This intra-household survey collects information related to household characteristics, farm production, decision-making, CSA adoption, access to agro-climate...

To complement field studies, a greenhouse study was conducted using plastic cylinders with soil inserted into PVC pipes, to determine the relationship between grain yield obtained under field conditions with...

Replication Data for:Biological nitrification inhibition by Brachiaria grasses mitigates soil nitrous oxide emissions from bovine urine patches

Ryan C. Byrnes, Jonathan Núñez, Laura Arenas, Idupulapati M Rao, Catalina Trujillo, Carolina Alvarez, Jacobo Arango, Frank Rasche & Ngonidzashe Chirinda
High nitrogen (N) concentration in bovine urine, which generally exceeds plant N uptake rates, results in the formation of hotspots of N loss when bovine urine is deposited on grazed pasture soils. High spatial variability in the distribution of urine patches in grazed pastures poses a major challenge to mitigate N losses. Some exudates from the roots of several tropical forage grasses were shown to inhibit the activity of soil nitrifiers; a process known as...

Replication Data for: Phytoplasma infection of a tropical root crop triggers bottom-up cascades by favoring generalist over specialist herbivores

Kris A. Wyckhuys
We tested the hypothesis that a Candidatus Phytoplasma causing cassava witches’ broom (CWB) on cassava (Manihot esculenta Grantz) is altering species composition of invasive herbivores and their associated parasitic hymenopterans. We conducted observational studies in cassava fields in eastern Cambodia to assess the effect of CWB infection on abundance of specialist and generalist mealybugs (Homoptera: Pseudococcidae), and associated primary and hyper-parasitoid species. Fields were selected as follows: Chetborey, Changchrong (12.58275°, 106.07681°), Chetborey, Sambuk (12.64369°, 106.06290°),...

Replication Data for: Audience Costs and the Dynamics of War and Peace

Casey Crisman-Cox & Michael Gibilisco
We estimate audience costs and examine their substantive effects on the evolution of interstate disputes by using an infinitely repeated and dynamic game of crisis escalation. Unlike past efforts, our approach estimates country-specific audience cost parameters without replying on proxy variables, e.g., democracy measures. Contrary to intuition, increases in a country's audience costs encourage it to initiate disputes in equilibrium, because the costs serve as a commitment device during the subsequent crisis, incentivizing the country...
