  • A longitudinal study of the effect of integrated literacy and basic education programs on women's participation in social and economic development in Nepal
    Burchfield, S.; Hua, H.; Baral, D.; Rocha, V. (Washington, DC: WID, USAID, 2002)
    The Girls' and Women's Education Policy Research Activity in Nepal investigated the impact of women's literacy programs by examining measures of socio-economic status, as well as indicators of women's social and economic development, including: 1) literacy and education, 2) children's education, 3) family and reproductive health, 4) participation in income-earning activities, 5) community participation, and 6) political participation. The study examined two integrated literacy programs: the Basic and Primary Education Project (BPEP) and the Health Education and Adult Literacy (HEAL) program. This study tested three hypotheses concerning the impact of integrated literacy programs on development. These hypotheses focused on respondents' awareness (knowledge and attitudes) and behavior (practice and skills). The hypotheses were; Women who participate in women's integrated literacy programs:

    New Ediacara fossils preserved in marine limestone and their ecological implications
    Chen, Z.; Zhou, C.; Xiao, S.; Wang, W.; Guan, C.; Hua, H.; Yuan, X. (Nature Publishing Group, 2014-02-25)
    Ediacara fossils are central to our understanding of animal evolution on the eve of the Cambrian explosion, because some of them likely represent stem-group marine animals. However, some of the iconic Ediacara fossils have also been interpreted as terrestrial lichens or microbial colonies. Our ability to test these hypotheses is limited by a taphonomic bias that most Ediacara fossils are preserved in sandstones and siltstones. Here we report several iconic Ediacara fossils and an annulated tubular fossil (reconstructed as an erect epibenthic organism with uniserial arranged modular units), from marine limestone of the 551-541 Ma Dengying Formation in South China. These fossils significantly expand the ecological ranges of several key Ediacara taxa and support that they are marine organisms rather than terrestrial lichens or microbial colonies. Their close association with abundant bilaterian burrows also indicates that they could tolerate and may have survived moderate levels of bioturbation.
