The Star Planet Activity Research CubeSat (SPARCS) will be a 6U CubeSat devoted to photometric monitoring of M dwarfs in the far-ultraviolet (FUV) and near-ultraviolet (NUV) (160 and 280 nm respectively), measuring the time-dependent spectral slope, intensity and evolution of M dwarf stellar UV radiation. The delta-doped detectors baselined for SPARCS have demonstrated more than five times the in-band quantum efficiency of the detectors of GALEX. Given that red:UV photon emission from cool, low-mass stars can be million:one, UV observation of thes stars are susceptible to red light contamination. In addition to the high efficiency delta-doped detectors, SPARCS will include red-rejection filters to help minimize red leak. Even so, careful red-rejection and photometric calibration is needed. As was done for GALEX, white dwarfs are used for photometric calibration in the UV. We find that the use of white dwarfs to calibrate the observations of red stars leads to significant errors in the reported flux, due to the differences in white dwarf and red dwarf spectra. Here we discuss the planned SPARCS calibration model and the color correction, and demonstrate the importance of this correction when recording UV measurements of M stars taken by SPARCS.
An Examination of the Partnerships Between Western Nonprofits and Nonprofits in Developing Countries
This project outlines an examination of partnerships between Western-based nonprofit organizations and local nonprofits in developing nations. While these partnerships have the potential to address issues of cultural sensitivity and community empowerment, little is known about their best practices and potential pitfalls. This project aims to address this gap by using a case study approach and qualitative methods to examine partnerships between a Western-based nonprofit organization and local nonprofits in Southeast Asia. The project involved semi-structured interviews with staff and board members of all organizations and a review of organizational documents such as annual reports and communication efforts.
