This study investigates preferences of visitors to the Discovery Museum (in North East England) with respect to opportunities to develop social capital. The extent to which museums generate social capital is largely unknown, but museums have potential opportunities to develop this type of capital. This study uses a stated preference choice experiment (CE) technique to estimate museum visitor preferences towards social capital opportunities. The findings indicate that visitors have a preference for visiting a museum with another individual(s); and that the provision of participatory activities, extended opening hours and locally related displays would generate more social capital among visitors and in society. 相似文献

The Seoul National University Nanoelectronics Institute (SNI) was established in 1996 by an interdisciplinary team of university researchers working together to develop a practical fabrication method for ‘tera-level’ single-electron semiconductor devices. The technical and organizational experiment of the SNI ended abruptly with the Asian financial crisis of 1997 as LG Semiconductor, SNI's patron, faced difficulties. This paper places this episode within the historical context of the development of science and technology in post-liberation South Korea as it coped with the overwhelming forces of globalization since the late 1970s. As the global high-tech trade war escalated in the 1980s, the South Korean government pursued the ‘technology drive policy,’ which emphasized the importance of directed basic research in university laboratories. The increased public and private support for university research transformed a few elite universities from teaching-oriented to research-focused institutions, especially in engineering and science. The new generation of research-intensive academics spearheaded the new national strategy of leapfrogging into the cutting-edge of global technology for the first time in the nation’s modern history. 相似文献

The power tiller was central to the modernization of agricultural practices in East Asia during the latter part of the twentieth century. The small-scale, two-wheeled, walking-type power tiller was adapted from the European garden tractors by Japanese farmer-inventors in the 1920s, and then imported to South Korea in the early 1960s. This article traces the global technology circuit for power tillers, as well as their troublesome entry into the South Korean socioeconomic landscape in the 1960s and 1970s. Once the South Korean manufacturing industry for power tillers established itself, the agricultural machine was embroiled in a controversial political debate over landownership structures, which had profound implications for the very place of agriculture in modern South Korea. In the process of this extended debate, the social meaning of the power tiller itself went through significant change. 相似文献

A Reexamination of Output Convergence in the U.S. States: Toward Which Level(s) are they Converging?
ChiYoung Choi 《Journal of regional science》2004,44(4):713-741
Abstract. This paper reexamines the issue of output convergence among the 48 states in the continental United States. Implementing multiple panel data techniques to state per capita output during the period 1929–2001 reveals little evidence of stochastic convergence in all 48 states, but some evidence among collections of states at the regional level. This observation may suggest that output convergence in the United States has proceeded among geographically neighboring states rather than among distant states, notwithstanding the nearly complete integration of product and factor markets. Our findings appear to be robust to a subsample analysis, although the intensity of convergence varies with the choice of output measure and deflator. Industrial structures and geographic proximity are considered as potential explanations for the regional pattern of output growth dynamics. 相似文献

Intra-European family migration has extended the realm in which families live and work in Europe. This paper joins a limited number of recent attempts to analyse family migration using a children-in-families approach [Bushin, N. 2009. Researching Family Migration Decision-Making: A Children-in-Families Approach.” Population, Space and Place, 15: 429–443]. In contrast to existing studies on this theme, our focus is on children's migration decision-making, experiences of step-migration and experiences of separation from parents during processes of intra-European family migration. Little is known about children's views and experiences of step-migration and separation from their parent(s) during family migration. Such experiences have implications for the spatial and temporal construction of family and childhood in Europe, where transnational mobility is increasing. This paper discusses children's experiences of separation in two research contexts, Scotland and the Republic of Ireland, to illustrate common features of the phenomena. The paper analyses family relationships relevant to migration decisions and explains their effects on children's agency, as well as on family integrity itself. 相似文献

The article develops a new method that compares activity‐travel patterns in both terms of the sequential order of activities and the shape of activity‐travel trajectory in time and space. The similarity of the list of activities and their order between activity‐travel patterns are computed by a sequence alignment method. The shape of activity‐travel trajectory is compared between the patterns using a path similarity technique that captures the direction and speed of a movement from the current location and the duration of staying at each location. The comparison results, therefore capture how people move around in three‐dimensional space–time choreography that indicates how people conduct which activities in what order. A total of 1,000 individuals are sampled from the data of 2016 Household Travel Survey, South Korea. The data provide the information of individual activity‐travel behavior and personal characteristics. The suggested method computes the pairwise distance matrix, and Ward clustering algorithm segments the pattern groups of similar activity sequences and space–time trajectories. A CHAID analysis then associates personal and household characteristics with the pattern groups to identify important factors for the segmentation. The analysis provides a significant implication in both terms of research and practice in transportation. 相似文献

This study presents an algorithm for measuring the time‐distance accessibility based on the flow data of actual transportation networks and examines resulting accessibility distributions. Specifically, we construct an extended graph of the transportation network to take into account not only the average speed and transfer time extracted from the data set but also various possible trajectories taken via transfers. Employing the modified Floyd algorithm which finds the shortest time distance, we compute the time‐distance accessibility of every bus stop in the Seoul bus system, which yields distinctive skew distributions. We then introduce a time‐distance cutoff to focus on effective connections and probe the emergent spatial distributions as the cutoff is varied. Revealed are the characteristic scales as well as spatial structures of the system. It is suggested that the time‐distance accessibility can serve as a significant measure to describe and predict the urban land use pattern. 相似文献

The semi-domestic status of the European fallow deer (Dama dama dama) renders its ancient biogeography a reflection of human activity with the potential to provide important insights into the movement, trade patterns and ideology of past societies. Given this potential, fallow deer have received surprisingly little attention from scientists within the fields of archaeology, biology and zoology. Here we present new AMS radiocarbon dates, stable carbon and nitrogen isotope data and genetic evidence (the first ancient DNA sequences for the species) resulting from the analysis of a set of remains recovered from the Roman settlement at Monkton on the Isle of Thanet, Kent, UK. By viewing our results against the very limited available comparative data, this paper provides new information for the establishment and management of fallow deer in Britain. We argue that much more could be achieved with even a slight increase in sample sizes and a plea is made for greater research into this culturally significant species. 相似文献

Although all of the Korean medieval mummies found up to the present time have shown relatively well‐preserved brains, relevant biomedical information has been difficult to acquire owing to the obstacles to obtaining permission to conduct invasive investigations. However, recently we were able to secure permission to investigate, through various forms of examination including dissection, a well‐preserved brain found in a lime‐soil mixture barrier (LSMB) tomb in Yongin, Korea, because the remains found within the tomb were mostly skeletal. As in the cases of mummified brains from tombs found in other countries, the current Yongin case showed well‐preserved grey and white matter within well demarcated brain lobes, on which sulci and gyri could be identified. On histological examination, we found that the remaining brain tissue was composed mainly of lipids, which seems to correspond to the preserved myelin sheath. The present paper is the first report on the general preservation status of a mummified brain found in Korea. Moreover, because mummified brains are found quite frequently in LSMB medieval tombs, this study could provide a good basis upon which further such palaeo‐neuropathological studies can be progressed.
