The purpose of the NCI Pathway to Independence Award for Early-Stage Postdoctoral Researchers (K99/R00) program is to increase and maintain a strong cohort of new and talented, NCI-supported, independent investigators. This program is designed for postdoctoral fellows with research and/or clinical doctoral degrees who do not require an extended period of mentored research training beyond their doctoral degrees. The objective of this award is to facilitate a timely transition of these fellows from their mentored, postdoctoral research positions to independent tenure-track (or equivalent) faculty positions. The program will provide independent NCI research support during this transition to help awardees to launch competitive, independent research careers. Researchers in the scientific areas of cancer control, cancer prevention and cancer data sciences are especially encouraged to work with their institutions to apply.This notice of funding opportunity (NOFO) is for basic science experimental studies involving humans, referred to in NOT-OD-18-212 as prospective basic science studies involving human participants. These studies fall within the NIH definition of a clinical trial and also meet the definition of basic research.

REQUEST FOR EXPRESSIONS OF INTEREST (CONSULTING SERVICES – Individual Consultants) Country: Grenada Name of Projects: Caribbean Regional Connectivity and Logistics MPA Assignment Title: Consultant for technical assistance for business processing reengineering and definition of digital systems in the port ecosystem, and establishment of an institutional governance framework for port ecosystem digitalization. Reference No.: GD-MIT-537771-CS-INDV Background The Government of Grenada, in collaboration with the World Bank Group, is embarking on a transformative journey toward a digitally empowered future. The Caribbean region faces persistent connectivity and logistics challenges, including high transport costs, fragmented infrastructure, and limited inter-island connectivity, which constrain trade, economic growth, and regional integration. Outdated port and airport systems and heavy reliance on maritime transport further contribute to inefficiencies and supply chain vulnerabilities. In response, the World Bank is supporting the preparation of the Caribbean Connectivity and Logistics Regional Program (MPA), a multi-phase initiative aimed at enhancing the efficiency, sustainabil... |
