Bridging the divide between studies on disaster risk reduction education and child-centred disaster risk reduction: a critical review

There has been a recent increase in the body of knowledge related to children and disasters. These studies converge into three main fields of research: the impact of disasters on children and their psychological recovery, the integration of disaster risk reduction (DRR) into the education sectors and children’s participation in DRR. This article provides a literature review of the two latter fields of research where the focus is on reducing disaster losses and building resilience prior to a disaster. Overall, 48 studies are critically reviewed and compared in relation to the strengths and weaknesses of their aims, methods, locations of research, impact, and outcomes. The review identified a number of differences between the two fields and significant opportunities for linking the two approaches, sharing lessons and knowledge. Based on the review, recommendations for further research are outlined.     

暗潮汹涌的“大汉贵州军政府”

武昌起义后贵州各界仓促应变,携手组成大汉贵州军政府。新政府中的各实力派因宗旨不同。渊源各异,而各行其是,由此导致军政府的最终解体。本文围绕组成大汉贵州军政府的自治学社、宪政预备会、新军三大力量之间的政治互动,重新审视这一问题,以期进一步梳理大汉贵州军政府的兴衰历程。     

Parameters in the use of pXRF for archaeological site prospection: a case study at the Reaume Fort Site,Central Minnesota

Field portable/hand-held x-ray fluorescence (pXRF) analyzers have been characterized as potentially useful for archaeological site prospection, but little has been published on the parameters of their use in this manner. The purpose of this study is to explore whether the variability of surface geochemistry as characterized with a pXRF analyzer corresponds with subsurface archaeological features at a site subsequently excavated, and what conditions influence the success of this endeavor, including feature depths, soil moisture, and sample processing. A 520 m² within-site area was systematically surveyed on a 2 m interval, within which several types of archaeological features were excavated (chimney bases, wall trenches, and a bonebed of faunal waste), taking readings in situ and collecting samples for ex situ testing (undried, dried but not powdered, and dried/powdered). The four different tests of each grid location, analyzed through univariate and multivariate tests, showed that the pXRF surface data does correspond with some types of subsurface features when those features are very shallow (within 5 cm of surface level) and are associated with clayey fills. Further, the data from the subsurface samples provides excellent distinction of feature fills from other sediments, regardless of sample preparation. In situ surface survey with pXRF analyzers may however be adequate for sites with a thorough baseline geochemical database.     

Using a Web-based Resource to Prepare Students for Fieldwork: Evaluating the Dark Peak Virtual Tour

This paper reports on development of a Dark Peak website and its use to prepare first-year geography students for a one-day physical geography field course in the south Pennines. The Virtual Tour (VT) component of the website is the main focus of this paper. Pre- and post-fieldwork evaluations of the first version of the VT by 195 students are presented with the revisions undertaken as a result of this feedback. Recommendations for the design and implementation of virtual fieldwork websites are made. The current version is available at http://www.art.man.ac.uk/Geog/fieldwork/     

Advice and reflections for a university teacher beginning an academic career

Although graduate programs typically prepare university students well for research activity, many have been less successful in educating for other aspects of academic careers. This article discusses Iain Hay's “Letter to a New University Teacher,” which has been used internationally to help new lecturers beginning their career. Prepared as an autoethnographic account for a recent graduate, “The Letter” distils principles held to underpin a successful academic career. Five university teachers and academic managers discuss critically the content and their applications of “The Letter” and make some suggestions for its use in continuously transforming higher education contexts.     

Characterisation and blind testing of radiocarbon dating of cremated bone

The success of radiocarbon dating of burned or cremated bones depends on the exposed temperature during burning and the degree of re-crystallisation of the inorganic bone matrix. We present a method for characterisation of likely cremated bones by employing visual inspection, infrared spectrometry and carbon stable isotope analysis on the bio-apatite fraction. The method of radiocarbon dating of cremated bones was tested by dating paired samples of bone and associated context materials such as pitch, charcoal and a dendrochronologically dated oak coffin. The dating of these paired test samples were largely performed as blind tests and showed excellent agreement between pitch and bone. The weighted mean age difference of all test samples is observed to −9 ± 60 ¹⁴C yr. To test the indicators and the effects of the degree of burning, a Late-Neolithic human individual has been studied, as this individual exhibits the full spectrum from low temperature burning (charred) to high temperature (“cremated”) from one end of a single bone to the other. This is reflected as a marked step in numerous parameters as well as in a significant difference in ¹⁴C age between the charred and the cremated bone samples.     

Comparison of rapid preparation methods for Pb isotope analysis of high-Pb ceramic glazes: A case study of late medieval Besztercebánya/Banská Bystrica-type stove tiles

This study identified the provenance of Pb flux used in the production of the glaze of unique, high-quality late medieval stove tiles from the northern part of the Carpathian Basin, and elaborated and evaluated a fast preparation process to measure Pb isotope ratios in high-Pb glazes. We compared three different methods of preparation. Method 1 consisted of the dissolution of bulk chips of glaze, dilution of the solution and mass spectrometric analysis without Pb purification. Method 2 collected the Pb from the surface of the glaze with acid-impregnated swabs, subsequent dilution and direct analysis of the sample solution. Method 3 used solutions from method 1, extraction of Pb by ion-exchange chromatography and analysis of the purified Pb. Each preparation method produced a similar Pb isotope ratio. The majority of the Pb isotope ratios fall into one group and indicate that lead imported from the Krakow–Silesia mining region was mainly used for production of the glazes of the stove tiles made by different workshops.     

Producing Web Pages for Assessment

This paper provides a review of the practices and tensions informing approaches to professional development for early career academic geographers who are teaching in higher education. We offer examples from Britain, Canada, Nigeria and the USA. The tensions include: institutional and departmental cultures; models that offer generic and discipline-specific approaches; the credibility of alternative settings for professional development in teaching and learning; the valuing of professional development and of teaching in academic systems of reward and recognition; and the challenges of balancing professional and personal life. We summarize concepts of good practice and suggest opportunities for future research.     

Improving the preparation for fieldwork with ‘IT’: Two examples from physical geography

Abstract

Two potential roles for information technology (IT) to enhance the preparation phase for fieldwork are investigated. In the first initiative, a prototype geographical information system (GIS) is developed to support local fieldwork activity. The second initiative develops computer‐based briefing tutorials to prepare students for residential field classes. By enhancing the preparatory phase of fieldwork, students are more quickly acclimatised once they arrive at the field site, they are better able to focus on the key issues, and valuable time in the field can be utilised more effectively.
