Other Direct Costs – This is a budget “catch-all” for miscellaneous costs, such as human subject costs, animal costs, per diems, publication costs, participant costs, tuition and fees.
The budget should break out each particular type of charge. For example, page charges – $500/month; phone charges for collaborators' conference calls – $200/month; animal per diems – $500/month; independent lab assay analyses – $100/month.
