No full textIn January 2008 the Eritrean capital of Asmara witnessed a theatre production that did not sit easily with the cultural imaginary of the country. Performed by a group of university graduates rather than the well-versed artists in government employ, Beyene Haile's Weg'i Libi, or Heart-to-Heart Talk, caused a stir among the local art-loving community in that it defied common strands of Eritrean theatre arts. Difficult to understand, with no clear plot or clear-cut message, it nonetheless drew crowds during the two weeks of its performance, largely because, as Christine Matzke suggests in this article, it allowed audiences to participate in the intellectual flânerie presented on stage. Basing her article on material collected in autumn 2008 and spring 2010, the author here provides an interpretation of the play and an outline and contextualization of its production process. Christine Matzke has spent well over a decade researching Eritrean theatre arts and cultural production. Her publications include the co-edited African Theatre 8: Diasporas (2009) and Postcolonial Postmortems (2006) on transcultural crime fiction. She teaches at the University of Bayreuth.</jats:p
Direct, high-resolution measurement of furrow stiffening during division of adherent cells
No full textIt is unclear whether cell division is driven by cortical relaxation outside the equatorial region or cortical contractility within the developing furrow alone. To approach this question, a technique is required that can monitor spatially-resolved changes in cortical stiffness with good time resolution. We employed atomic force microscopy (AFM), in force-mapping mode, to track dynamic changes in the stiffness of the cortex of adherent cultured cells along a single scan-line during M phase, from metaphase to cytokinesis. Video microscopy, which we used to correlate the AFM data with mitotic events identified by light microscopy, indicated that the AFM force-mapping technique does not perturb dividing cells. Here we show that cortical stiffening occurs over the equatorial region about 160 seconds before any furrow appears, and that this stiffening markedly increases as the furrow starts. By contrast, polar relaxation of cells does not seem to be an obligatory event for cell division to occur

Estimating the impact of community use of the Mavuradonha Wilderness in Zimbabwe
No full textLegislated wilderness, first created in the United States with the Wilderness
Act of 1964, is being more widely established internationally. The Mavuradonha Wilderness
Area in Zimbabwe is the first wilderness set up to be managed by the local community.
Because of the importance of both conservation and rural development goals in this context,
community use of the wilderness is a contentious issue in the development of a management
strategy. The purpose of this study is to estimate the impacts of community use of the area.
Measurements of several environmental variables were taken along random transects and
cattle trails extending into the wilderness. Results indicate that a buffer zone of generally one
kilometer is being lightly impacted, and the author suggests that allowing the community
continued access to resources and cattle grazing in the area will result in little environmental
impact and much local support of the wilderness
Hardboiled Feminism: Laura as an Interrogation of the Detective Genre
No full textLaura holds a privileged place in detective fiction and film noir, yet Vera Caspary’s novel has received little critical attention. This paper asserts that Caspary’s novel, written within a context of a hypermasculine culture, constitutes a significant feminist revision of the genre that disrupts the hardboiled/scientific binary. By self-reflexively reworking the tropes of the hardboiled detective and using a casebook format associated with scientific detectives, the author crafts a narrative free from the strictures of a male-centered genre, creating a noir novel that boldly breaks from its hardboiled contemporaries
