    A Case Study of Makerere University in Uganda through the Lens of U.S. Land-Grant Higher Education

    This case study examines Makerere University through the lens of U.S. land-grant ideal and normative domains in order to provide a deeper understanding of global higher education. A case study uses multiple types of data to create a holistic perspective. As well as interviewing Makerere stakeholders representing diverse sectors, numerous documents and different types of media were analyzed enabling a triangulation of data. Six major themes emerged focusing on Makerere’s aspiration to be a research-led institution, the impact of neoliberalism, challenges in undergraduate education, the importance of reputation and saga, the ever-present role of the Ugandan government, and the continuing effects of colonialism. These findings are discussed in relationship to the land-grant domains, in particular the tensions and contradictions which can result in university instability

    Framing females in sport: The pictorial and written coverage of female athletes in Sports Illustrated from 1996-2005

    Current research reveals that mass media framing techniques used in sports media result in a lack of coverage for female athletes, a perception of “socially acceptable” sports for women, and the feminization of sports. Due to the historical sports victories occurring after 1996, such as the 1996 Olympics, the formation of the WNBA, and the US World Cup victory, there is a perceived and actual change in the popularity and participation in female sports. This study sought to determine whether these sports victories for women have been reflected in volume and in quality on the cover photographs and cover articles of Sports Illustrated from 1996 - 2005. A content analysis of 641 depicted subjects revealed significant differences between the photographic coverage o f male and female athletes and story content related to gender. Further, this study revealed that media framing is occurring through more subtleties and that it is often packaged under the label of female progress. These differences have implications in our understanding of female athletes, as well as in the future involvement of females in sports

    E-cigarette use among women of reproductive age: Impulsivity, cigarette smoking status, and other risk factors.

    INTRODUCTION: The study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant. METHOD: Survey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44years from the US. Half (n=400) reported current, daily smoking and half (n=400) reported smokingsociodemographics, tobacco/nicotine use, and impulsivity (i.e., delay discounting & Barratt Impulsiveness Scale). Predictors of smoking and e-cigarette use were examined using logistic regression. RESULTS: Daily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it was associated with greater impulsivity and illegal drug use. E-cigarette use was associated with hookah use, and for never smokers only with use of cigars and other nicotine products. CONCLUSIONS: E-cigarette use among women of reproductive age varies by smoking status, with use among current smokers reflecting attempts to quit smoking whereas among non-smokers use may be a marker of a more impulsive repertoire that includes greater use of alternative tobacco products and illegal drugs

    Inclusion of seasonal variation in river system microbial communities and phototroph activity increases environmental relevance of laboratory chemical persistence tests

    Regulatory tests assess crop protection product environmental fate and toxicity before approval for commercial use. Although globally applied laboratory tests can assess biodegradation, they lack environmental complexity. Microbial communities are subject to temporal and spatial variation, but there is little consideration of these microbial dynamics in the laboratory. Here, we investigated seasonal variation in the microbial composition of water and sediment from a UK river across a two-year time course and determined its effect on the outcome of water-sediment (OECD 308) and water-only (OECD 309) biodegradation tests, using the fungicide isopyrazam. These OECD tests are performed under dark conditions, so test systems incubated under non-UV light:dark cycles were also included to determine the impact on both inoculum characteristics and biodegradation. Isopyrazam degradation was faster when incubated under non-UV light at all collection times in water-sediment microcosms, suggesting that phototrophic communities can metabolise isopyrazam throughout the year. Degradation rate varied seasonally between inoculum collection times only in microcosms incubated in the light, but isopyrazam mineralisation to 14CO2 varied seasonally under both light and dark conditions, suggesting that heterotrophic communities may also play a role in degradation. Bacterial and phototroph communities varied across time, but there was no clear link between water or sediment microbial composition and variation in degradation rate. During the test period, inoculum microbial community composition changed, particularly in non-UV light incubated microcosms. Overall, we show that regulatory test outcome is not influenced by temporal variation in microbial community structure; however, biodegradation rates from higher tier studies with improved environmental realism, e.g. through addition of non-UV light, may be more variable. These data suggest that standardised OECD tests can provide a conservative estimate of pesticide persistence end points and that additional tests including non-UV light could help bridge the gap between standard tests and field studies

    Laser spot welding of laser textured steel to aluminium

    Get PDF
    Laser welding of dissimilar metals (steel and aluminium) was investigated with the aim to increase the maximum tensile shear load of the Fe-Al joints. The increase was achieved by texturing the surface of steel prior to the laser spot welding process which was performed in a lap-joint configuration with the steel positioned on top of the aluminium and with a texture faced down to the aluminium surface. This configuration enabled an increase of the bonding area of the joints, because the molten aluminium filled in the gaps of the texture, without the need of increasing the process energy which typically leads to the growth of the intermetallic compounds. Different textures (containing hexagonally arranged craters, parallel lines, grid and spiral patterns) were tested with different laser welding parameters. The Fe-Al joints obtained with the textured steel were found to have up to 25% higher maximum tensile-shear load than the joints obtained with the untextured steel
