A holistic approach to enhance the use of neglected and underutilized species: the case of Andean grains in Bolivia and Peru
The IFAD-NUS project, implemented over the course of a decade in two phases, represents the first UN-supported global effort on neglected and underutilized species (NUS). This initiative, deployed and tested a holistic and innovative value chain framework using multi-stakeholder, participatory, inter-disciplinary, pro-poor gender- and nutrition-sensitive approaches. The project has been linking aspects often dealt with separately by R&D, such as genetic diversity, selection, cultivation, harvest, value addition, marketing, and final use, with the goal to contribute to conservation, better incomes, and improved nutrition and strengthened livelihood resilience. The project contributed to the greater conservation of Andean grains and their associated indigenous knowledge, through promoting wider use of their diversity by value chain actors, adoption of best cultivation practices, development of improved varieties, dissemination of high quality seed, and capacity development. Reduced drudgery in harvest and postharvest operations, and increased food safety were achieved through technological innovations. Development of innovative food products and inclusion of Andean grains in school meal programs is projected to have had a positive nutrition outcome for targeted communities. Increased income was recorded for all value chain actors, along with strengthened networking skills and self-reliance in marketing. The holistic approach taken in this study is advocated as an effective strategy to enhance the use of other neglected and underutilized species for conservation and livelihood benefits
Education Equity for Undocumented Graduate Students and the Key Role of My Undocumented Life
An estimated 454,000 undocumented students are enrolled in higher education, with ten percent of these students (45,400 students) studying in graduate school. While the field of higher education has worked to develop equitable policy and practice for undocumented students at the undergraduate level, a focus on graduate school is imperative. In this article, we reflect on what we have learned working with undocumented students in graduate school through our work with My Undocumented Life (MUL), a website with almost two million views that provides up to date information and resources for undocumented immigrants. We discuss the challenges that undocumented students face in pursuing graduate school, such as charting pathways to graduate school in isolation, seeking information specific to undocumented students, decisions around whether to disclose one’s immigration status, and lack of financial aid opportunities. We also provide recommendations for universities to build programs specifically for undocumented students in graduate school

Two spatially separated phases in semiconducting RbFeS
We report neutron scattering and transport measurements on semiconducting
RbFeS, a compound isostructural and isoelectronic to the
well-studied FeSe K, Rb, Cs, Tl/K) superconducting
systems. Both resistivity and DC susceptibility measurements reveal a magnetic
phase transition at K. Neutron diffraction studies show that the 275 K
transition originates from a phase with rhombic iron vacancy order which
exhibits an in-plane stripe antiferromagnetic ordering below 275 K. In
addition, interdigitated mesoscopically with the rhombic phase is an ubiquitous
phase with iron vacancy order. This phase has a
magnetic transition at K and an iron vacancy order-disorder
transition at K. These two different structural phases are closely
similar to those observed in the isomorphous Se materials. Based on the close
similarities of the in-plane antiferromagnetic structures, moments sizes, and
ordering temperatures in semiconducting RbFeS and
KFeSe, we argue that the in-plane antiferromagnetic order
arises from strong coupling between local moments. Superconductivity,
previously observed in the FeSeS system, is absent
in RbFeS, which has a semiconducting ground state. The
implied relationship between stripe/block antiferromagnetism and
superconductivity in these materials as well as a strategy for further
investigation is discussed in this paper.Comment: 7 pages, 5 figure
