Anti-Americanism and the Cold War : on the DEFA Berlin films

Sustained by well-established anti-American stereotypes and clichés, the romance between German and American culture has been a key ingredient of German cinema since its inception. The encounter with American mass culture produced compelling stories of infatuation and seduction, but also of conquest and surrender

Interactive-engagement vs traditional methods: A six-thousand-student survey of mechanics test data for introductory physics courses

The complete report from Richard Hake's long-term study of interactive engagement (IE) techniques and their effect on the understanding of physics by non-physics majors. The study analyzed diverse student populations in high schools, colleges, and universities and used pre- and post-instruction testing to determine the gains in each group. IE techniques were shown to improve student's understanding at a significantly higher rate than traditional instruction. Additionally, these IE techniques are applicable to teaching a wide range of topics. Educational levels: Graduate or professional

Colorful worlds : the West German revue film of the 1950s

On the following pages you will meet a strange cast of characters: field slaves from Mississippi, steel bands from Trinidad, sheriffs from Puerto Rieo. Mexican campesinos and senioritas, and, of course, the European musical stars who performed these American stereotypes in one of the most disparaged genres of German cinema, the 1950s West German revue film

Genetic, evolutionary and plant breeding insights from the domestication of maize.

The natural history of maize began nine thousand years ago when Mexican farmers started to collect the seeds of the wild grass, teosinte. Invaluable as a food source, maize permeated Mexican culture and religion. Its domestication eventually led to its adoption as a model organism, aided in large part by its large chromosomes, ease of pollination and growing agricultural importance. Genome comparisons between varieties of maize, teosinte and other grasses are beginning to identify the genes responsible for the domestication of modern maize and are also providing ideas for the breeding of more hardy varieties

A Panel Data Analysis on FDI and Exports

The present paper investigates the link between exports and the outward FDI stock using a panel of industries and seven EU countries for the period 1973-2004. In particular, we use the panel causality tests developed by Holtz-Eakin, Newey, and Rosen (1988). Estimates using system GMM estimators show that exports cause FDI but not vice versa. The long-run elasticity of the outward FDI stock with respect to exports is 0.78 and highly significant. Separate estimates by destination country yields the same result that exports cause outward FDI but the effect is only significant for the CEE countries and other developed countries (i.e. United States, Japan, Canada, Switzerland, Norway, etc.).exports, FDI, dynamic panel data methods

Topological Symmetry Groups of Complete Bipartite Graphs

The symmetries of complex molecular structures can be modeled by the {\em topological symmetry group} of the underlying embedded graph. It is therefore important to understand which topological symmetry groups can be realized by particular abstract graphs. This question has been answered for complete graphs; it is natural next to consider complete bipartite graphs. In previous work we classified the complete bipartite graphs that can realize topological symmetry groups isomorphic to $A_4$, $S_4$ or $A_5$; in this paper we determine which complete bipartite graphs have an embedding in $S^3$ whose topological symmetry group is isomorphic to $\mathbb{Z}_m$, $D_m$, $\mathbb{Z}_r \times \mathbb{Z}_s$ or $(\mathbb{Z}_r \times \mathbb{Z}_s) \ltimes \mathbb{Z}_2$.Comment: 26 pages, minor revisions; this is the final version accepted by Tokyo Journal of Mathematic

Persistence in Mathematics by Underrepresented Students: Experiences of a Math Excel Program

Success in mathematics by underrepresented and nontraditional college students is measured not only by academic performance (grades), but also by the continued participation and persistence of these students in mathematics coursework. The Math Excel program at Oregon State University attempts to build learning communities with a sharp academic focus in support of students concurrently taking introductory level mathematics courses. The Math Excel program is based heavily on Uri Treisman\u27s Emerging Scholars Workshop model of collaborative problem solving. In this article, we examine the experience of minority students in the Educational Opportunities Program participating in the Math Excel program. While the program had appeared successful in terms of improving academic performance in the concurrent mathematics course, the continued participation and persistence of these students in mathematics was disappointing. On a trial basis, structural changes were made to build a much stronger identification of the Math Excel learning community with a section of College Algebra. In the next term, there was a much higher incidence of participation in the subsequent Precalculus using the same Math Excel structure. While the collaborative problem solving activity provided in Math Excel was crucial to students\u27 successful academic performance, these results suggest that subtle issues related to students\u27 recognition of and identification with a learning community may be critically important to underrepresented and nontraditional students\u27 continued persistence in mathematics
