    Plans to reintroduce Atlantic salmon in Lake Ontario tributaries consists of stocking hatchery-reared fish yearly which will help to achieve a self-sustaining population. The issue with reintroduction remains in understanding the distribution of fishes after stocking. Environmental DNA (eDNA) provides a sensitive approach for monitoring that can offer inferences into fish distribution. I determined the distribution of stocked Atlantic salmon downstream from stocking sites using qRT-PCR and metabarcoding. I found that Atlantic salmon eDNA detection was more sensitive using qRT-PCR (51%) versus metabarcoding HTS (18.3%). However, metabarcoding provided data on fish community assemblages, which can help to monitor ecological interactions. I also found that eDNA and microsatellite markers genotyped and assigned an estimate number of individuals to 68.3% of the positive Atlantic salmon NGS data. This data indicates that eDNA and microsatellites can be used as a non-invasive method to quantify and monitor communities

    The response to iron supplementation of pregnant women with the haemoglobin genotype AA or AS

    The influence of haemoglobin genotype on the response to iron supplementation was studied in a randomized, double blind, placebo-controlled trial involving 497 multigravid pregnant women from a rural area of The Gambia. Women were randomly allocated to receive either oral iron (60mg elemental iron per day) or placebo. At 36 weeks of pregnancy, women who had received oral iron during pregnancy had higher mean haemoglobin, packed cell volume, plasma iron and ferritin levels than did women who received placebo. Iron supplementation of pregnant women with the AA haemoglobin genotype also resulted in increases in the packed cell volume (PCV) and haemoglobin level measured after delivery, and in the birth weight of the infant. However, in AS women PCV and haemoglobin level at delivery were lower in the supplemented group and supplementation was also associated with reduced birth weights. In malaria endemic areas, pregnant women with the haemoglobin genotype AS may not benefit from iron supplementation during pregnanc

    Making the Grade through the Front Door: Evaluation and Innovation in a Registered Practical Nurse to Bachelor of Science in Nursing Program

    Background: Education of nurses from a diploma to a degree is a global phenomenon. However, bridging is often seen as a ‘backdoor’ route to becoming a Registered Nurse and very little evaluation data exists to challenge this notion. Objectives: This research project was undertaken to explore student characteristics, academic performance, outcomes, and experiences in an RPN-to-BScN Bridging Program. Design: A mixed method design was employed. Student admission and registrarial data were examined in relation to student characteristics and academic performance. Secondary data analysis was conducted on focus group interviews with 110 students that explored their perceptions of the impact of the program on their lives. Setting: Data was collected through University databases and face to face focus groups. Participants: Admission and registrarial data for all students admitted to a nursing bridging program in Ontario, Canada, from 2005-2011 were analyzed. Participants in the qualitative focus group interviews included 110 students across all years of the program. Methods: Descriptive and analytical statistics provide insight into student performance and characteristics. Qualitative data analysis was conducted using NVivo 9 with multi-member teams. Results: Data analysis reveals important insights into student academic performance, including exploration of relevant variables such as ongoing and cumulative GPA, entrance GPA, and program completion. Qualitative analysis provides insight into how studying in the program affects students’ lives. Conclusions: RPN-to-BScN education is not a “back door” to a nursing degree. Rather, it is a front door, as rigorous and as personally and professionally transformative as we expect a 4-year BScN Degree to be

    Neoliberalism and University Education in Sub-Saharan Africa

    Get PDF
    This article reviews the history of university development in Sub-Saharan Africa (SSA) and discusses the impact of neoliberal policies. This will be followed by an examination of the problems facing universities in the region. The following questions will be explored: (a) Are the existing universities in SSA serving the development needs of the region? (b) Are these universities up to the task of moving SSA out of the predicaments it faces such as famine, HIV/AIDS, poverty, diseases, debt, and human rights abuses? Finally, the article argues that for universities to play a role in the development of the region, a new paradigm that makes university education a public good should be established

    Historical Missionary Activity, Schooling, and the Reversal of Fortunes: Evidence from Nigeria

    Get PDF
    This paper shows that historical missionary activity has had a persistent effect on schooling outcomes, and contributed to a reversal of fortunes wherein historically richer ethnic groups are poorer today. Combining contemporary individual-level data with a newly constructed dataset on mission stations in Nigeria, we find that individuals whose ancestors were exposed to greater missionary activity have higher levels of schooling. This effect is robust to omitted heterogeneity, ethnicity fixed effects, and reverse causation. We find inter-generational factors and the persistence of early advantages in educational infrastructure to be key channels through which the effect has persisted. Consistent with theory, the effect of missions on current schooling is larger for population subgroups that have historically suffered disadvantages in access to education
