Westminster College is a private, residential, undergraduate college with a curriculum based on the liberal arts. Located in Fulton, Missouri, the College was established in 1851 as Fulton College. The National Churchill Museum is a national historic site located on campus and includes the Church of St Mary, Aldermanbury. The church, designed by Sir Christopher Wren in 1667, was rebuilt on the campus to commemorate Sir Winston Churchill, who made his famous "Iron Curtain" speech at the college gymnasium in 1946. Mikhail Gorbachev gave a speech there in 1992, declaring the end of the Cold War. Wikipedia.

Agroforestry Systems | Year: 2013

Vegetative filter strips (VFS) have long been promoted as a soil conservation practice that yields many additional environmental benefits. Most previous studies have focused primarily on the role of vegetation and/or soil physical properties in these ecosystem services. Few studies have investigated the soil microbial community of VFS. Therefore, we examined potential differences in soil microbial community characteristics of claypan soil planted to VFS with differing vegetation and a traditional row-crop system in a maize-soybean rotation. Samples were tested for soil microbial function and community structure using dehydrogenase and fluorescein diacetate (FDA) hydrolysis enzyme assays and phospholipid fatty acid (PLFA) analysis, respectively. The grass VFS soil exhibited the greatest dehydrogenase activity levels and FDA activity was greater in the grass and agroforestry (i. e., tree-grass) VFS soils relative to the cropland soil. The PLFA analysis revealed community structural differences underlying these functional differences. The agroforestry VFS soil was characterized by a greater proportion of total bacteria, gram-negative bacteria, anaerobic bacteria and mycorrhizal fungi than the cropland soil. The grass VFS soil shared some characteristics with the cropland soils; but the grass VFS supported greater mycorrhizal fungi and protozoa populations. This work highlights differences in soil microbial function and community structure in VFS relative to cropland soil 12 years post VFS establishment. It also enhances our fundamental knowledge regarding soil microorganisms in VFS, which may aid in explaining some ecosystem services provided by VFS (e. g., decomposition of organic agrichemicals). © 2012 Springer Science+Business Media B.V.

National Identities | Year: 2010

This article explores the relationship between regionalism and fascism in interwar Alsace. Although fascism is usually characterized as hypernationalist, the relationship between regionalism and fascism in Alsace suggests something more complex. On the one hand, French and German fascist movements sought local legitimacy by co-opting issues of regional identity. Hypernationalism would have fallen on deaf ears. On the other hand, the Alsatian Bauernbund, a regionally based fascist movement, adapted fascist principles to strictly regional aims. The goal of fascism, in this case, was not necessarily national. A better way to understand the range of fascist interaction with regional identity is to see fascism as aggressively espousing the politics of spatial identity in a political environment that generally downplayed ethnic, regional or national sensitivities. Fascism offered a hierarchy of identity or belonging that embraced the socially powerful relationships of family, region and nation. 2010 Taylor & Francis.

Noise that masks communication signals can affect the evolution of signal form and decisions about when and where to communicate. For the many invertebrates that communicate using plant-borne vibrations, wind is considered to be the major source of environmental noise. However, the influence of wind-induced vibrations on signaling behavior has not been experimentally tested. We tested the hypothesis that wind-induced noise influences signaling behavior in a plant-feeding insect (the treehopper, Enchenopa binotata 'Ptelea') in which mating is preceded by a vibrational duet between females and mate-searching males. We first characterized the diel signaling patterns of males in the field to identify the wind conditions under which signaling typically takes place. We then experimentally tested two predictions of the hypothesis: (1) that males use gap detection to initiate signaling during relatively wind-free periods; and (2)that females respond less to signals given in the presence of wind-induced vibrations. Both predictions were met, indicating that wind-induced noise is an important influence on the behavior of insects that use plant-borne vibrations. © 2010 Springer-Verlag.

This is a quantitative study of 493 undergraduate engineering majors' intentions to persist in their engineering program. Using a multiple analysis of variance analysis, men and women had one common predictor for their intentions to persist, engineering career outcome expectations. However, the best sociocognitive predictor for men's persistence was not the same for women. Men's persistence in undergraduate engineering was predicted by their abilities to complete the required coursework. Women's persistence in undergraduate engineering depended upon their beliefs in getting good grades (A or a B). In brief, women's intentions to persist in undergraduate engineering were dependent upon higher academic standards compared to men. © 2009 Springer Science+Business Media, LLC.

In this study, we examined 96 undergraduate non-science majors' conceptions of stem cells, stem cell research, and cloning. This study was performed at a large, Midwest, research extensive university. Participants in the study were asked to answer 23 questions relating to stem cells, stem cell research, and cloning in an on-line assessment before and after instruction. Two goals of the instruction were to: (1) help students construct accurate scientific ideas, and (2) enhance their reasoning about socioscientific issues. The course structure included interactive lectures, case discussions, hands-on activities, and independent projects. Overall, students' understandings of stem cells, stem cell research, and cloning increased from pre-test to post-test. For example, on the post-test, students gained knowledge concerning the age of an organism related to the type of stem cell it possesses. However, we found that some incorrect ideas that were evident on the pre-test persisted after instruction. For example, before and after instruction several students maintained the idea that stem cells can currently be used to produce organs. © 2009 Springer Science+Business Media, LLC.
