ABSTRACT.  It is common in empirical regional economics to use total employment as an explanatory variable while investigating issues such as the level and distribution of income and migration. This paper argues that sector-specific changes in employment and labor market performance can have different effects on economic growth, the collection of tax revenue, migration, and the level and distribution of household income. As such, it is important to model sectors separately. We find that expansions in employment opportunities for a high-wage sector such as computer manufacturing or bioengineering, a medium-wage sector manufacturing, and the lower-wage sector of retailing have differing economic consequences for a small city. We use a data intensive computable general equilibrium model to obtain these results.  相似文献

Although geography has long associated itself with photography, the rapid advancement of technology has created a clear divide between the visual practices regularly used in wider society and the way photography is utilized by critical geographers in their teaching. We suggest the door is ajar for new modes of (geo)photographic thinking, and one visual tool at our disposal is social media applications that allow images to be instantly shared, analysed, and discussed. This article critically reflects on the use of Instagram to enhance student participation, engagement, and learning on a geography field course in Berlin. Based on interviews with students, their field journals, and our own critical reflections, this paper looks at some advantages of using Instagram in teaching geography, but also promotes caution and presents drawbacks to relying on instant visual digital methods.  相似文献

Video recording is increasingly becoming a favourable medium in archaeological research, particularly as an unconventional documentation tool that captures the elusive processes of ongoing interpretation in an audiovisual format. Our research forms part of the Personal Architectonics Through INteraction with Artefacts (PATINA) project, a project focused on the design of technologies for supporting research. Archaeological fieldwork is one of the research environments being studied by the project, and one of our primary concerns was to observe and record current research practices in the wild and to examine the influence of new technologies on those practices. This research brings together well-established and advanced observation techniques used in social sciences and computing fields such as human–computer interaction with archaeological research and presents the deployment of an off-the-shelf wearable camcorder as a recording interface in archaeological fieldwork. The article discusses the user evaluation methodology and the results, while addressing long-standing and timely theoretical discussions on the role of video recording in archaeological research.  相似文献

W. J. Thoms establisted a folklore column in The Athenaeum, a precursor to the one in Notes and Queries. It ran to thirty-five columns with eighty-seven separate contributions appearing intermittently between 1846 and 1849. These columns have not been examined in detail before. Presented here, after an initial discussion, is a listing, column by column, of the contributions to Thoms's column followed by a bibliography of all the pieces that appeared. Due to the use of ciphers and initials, very few of the contributors, save a small number, to this new discipline of folklore can be clearly identified.  相似文献

Excavation in and around a Medieval church in Gammertingen, Germany, revealed the skeletal remains of eight individuals dating to the 10th and 11th century AD. Archaeologists hypothesized that the individuals were the first members of a family later known as the Counts of Gammertingen, a medieval high nobility family. In an interdisciplinary approach, Strontium isotope and ancient DNA techniques were performed in order to test the hypothesis that the church was used as a family burial site and to investigate the provenance of family members. Seven of the eight individuals can be placed in a three-generation genealogy. The isotope analyses establish that the eighth individual had a different birthplace and possibly became a member of the Counts of Gammertingen through marriage. Further, genetic data revealed that distant relatives of the paternal lineage are still present in this area today. Thus, the combined results lead to a very detailed knowledge about a 1000-year old noble family.  相似文献

This article summarises the archaeological evidence for the existence of Evagoras' naval harbour at Salamis in North Cyprus, which ancient texts credit him with building c.410–400 BC. Based on a critical examination of previous surveys and his own on‐site observations, the author concludes there is indicative evidence of a constructed harbour c.800 m long, which was divided into two basins by a stone jetty, separated from the city by a stone wall and with some evidence of ship‐sheds at its north end. © 2012 The Author  相似文献
