More on assessment

This paper calls attention to the difficulties of broaching issues of 'race' and 'sex' in the classroom in the context of nation-wide institutional calls for multiculturalism. I argue that critical multicultural objectives can only be successful if: (1) faculty who take curricular and pedagogical risks are able to count on strong support from colleagues, departmental chairs and university administrators; (2) classroom realities of homophobia, sexism and racism are acknowledged at an institutional structural level to be societal in reach and global in scale; (3) we engage in evaluative strategies that are educative about the learning process; and (4) we stress to students the emotional realities and practical skills involved in learning about, and working through, social conflict and difference.     

Monuments on a migrating Nile

River courses migrate, but many Egyptologists plot the present-day River Nile on maps of the valley in archaeological times. This may have misled interpretations of ancient monuments and settlements. We show a river migrating rapidly on historical timescales in the Luxor region, sweeping > 5 km across the valley at rates on the order of 2–3 km per 1000 years. Satellite elevation data (SRTM), processed by a novel method, and Landsat imagery are used to trace ancient river levees and extend trends present in 200 years of archive maps thousands of years into the past. This supplements observations by Ptolemy (121–141 AD) and places local geo-archaeological studies in a wider spatial and temporal context. Satellite data are demonstrated to be a relatively quick and easy constraint upon ancient river courses, and a basis for investigations along the Egyptian Nile, even in logistically inaccessible regions.     

明清时期漳河平原段的河道变迁及其与“引漳济运”的关系

漳河是海河水系重要的支流。历史时期,在自然环境与人为因素的共同作用下,漳河平原段具有易淤、易决与易徙等特征。本文以明清(1368-1911年)为研究时段,对漳河的变迁过程进行了尽可能具体、详细的复原和定位。并在此基础上,探讨了漳河变迁的特点与规律。     

Cutting its coat according to the cloth: the Canadian Militia and staff training before the Great War

In 1909, Canada established the Militia Staff Course (MSC) to provide reserve officers with the basic staff skills they would need upon mobilization. At the time, the Militia severely lacked properly trained staff officers to run formations and draft mobilization plans. Although the course provided only elementary staff training, it reinforced the latent command and staff potential of a generation of officers, as later suggested by their effective and often exceptional service in the First World War. The MSC ultimately proved the first step towards developing a tradition of formal command and staff training in the Canadian Army.
