ABSTRACT

The aim of the article is to determine what a local Digital Agenda (DA) implies for ICT development at the local level and how such a policy can be realised in practice. The topic is discussed in relation to the EU and Swedish Digital Agendas, which have motivated the definition of a local DA for the examined Swedish municipality of Linköping. An analytical model is used both to examine the balance of supply-side and demand-side policies of the local DA, and in an attempt to determine what a local DA implies for local ICT development. The empirical material shows that local policy focused on supply-side strategies towards households and businesses, while demand-side policy was present to a greater extent in the management of the municipality’s own operations. The local authority has provided a major expansion in broadband infrastructure to rural areas of the municipality. This complies with mandates from local authorities to manage local infrastructure development and services to the local population. The authors conclude that the policy implications of the results suggest that although operations through the local DA are substantial, complementary measures to support increasing demands across households and businesses are important when dealing with challenges of uneven access and underutilisation of the large investments for ICT infrastructure.  相似文献

A combination of pollen and macrofossil analyses from six lakes at altitudes between 370 and 999 m above sea level (a.s.l.) in the Torneträsk area reflect the Holocene vegetation history. The main field study area has been the Abisko valley at altitudes around 400 m a.s.l. The largest lake, Vuolep Njakajaure has annually laminated (varved) sediments. The chronology and sedimentation rates in the pollen-influx calculations are based on varve yrs in this lake and on radiocarbon dated terrestrial plant macrofossils in the other lakes. A strong increase of mountain birch (Betula pubescens ssp. tortuosa) during the early Holocene with a tree-line c. 300 m above the present, indicates that the summer temperature was c. 1.5 °C higher than today, assuming that the land uplift has been 100 m since then. Scattered stands of pine (Pinus sylvestris) may have been growing in the area immediately after the deglaciation but a forest consisting of pine and mountain birch expanded first at low elevations and reached the eastern parts of the Torneträsk area at c. 8300 cal BP and the western parts at c. 7600 cal BP. The highest pine-birch forest limit was not reached until 6300 cal BP (110 m above present pine limit). Warm and dry conditions during the pine forest maximum led to lowering of the water level documented in Lake Badsjön in the Abisko valley about 1-1.5 m lower than today. Pine and mountain birch were growing at the maximum altitude until c. 4500 cal BP. Assuming that land uplift has been in the range of 20-40 m since the mid-Holocene, this implies that the temperature was then c. 1.5-2 °C higher than today. Rising lake-levels and lowering limits of pine and mountain birch since c. 4500 cal BP indicate a more humid and cool climate during the late Holocene.  相似文献

Research on small cities has begun to attract the attention of scholars who argue that contemporary urban scholarship, in its preoccupation with the largest and most advanced world-class cities, have largely ignored small to medium-sized cities. In China, although much attention has been paid to economically advanced urban centers, there actually has been a steady stream of work on small cities. This article profiles how a comparatively smaller city in western China attempts to market itself by selectively placing itself within various social–spatial and political–economic realities. Through Jinghong, we illustrate how local officials and planners attempt to center the city as a gateway to Southeast Asia. By activating, often discursively, multiscalar transborder strategies, local officials in Jinghong not only mobilize ethnic imaginaries, but they also adopt forms of entrepreneurial tactics to promote growth. Developmental strategies of Jinghong not only vacillate between (and draw on) both rural and urban resources; they are furthermore expected to alleviate rural poverty. Through highlighting the agency of small cities like Jinghong in China, this article speaks to the broader developmentalist critique of third- and fourth-world cities as an unfortunate footnote in global urban restructuring, often depicted as places of uniform marginalization and structural irrelevance. Indeed, by focusing on the geography of small cities and giving due attention to their size and proximity to rural spaces, case studies like Jinghong might yet point empathetically to different ways and imperatives of “being urban” where the weight that they carry can also be duly recognized.  相似文献

This article seeks to understand China’s new urban space production and associated state space rescaling through a microscopic investigation of urban investment and development corporations (UIDCs), based on a case study of Shanghai’s Songjiang New Town Development Corporation (SNTDC). It argues that the introduction of UIDCs as both developers and managers of designated urban regions is a creation of institutional reformation to accomplish customized place- and scale-specific spatial projects under the state strategy of new urban spatial development, playing an essential part in the rescaling of state space. UIDCs are economically independent of other social groups, politically bonded with the local government, and assume entrepreneurial and administrative functions within designated areas, acting as intermediary agents to enable local states greater capacity in governing new urban space production, engineering social change, and propelling economic development.  相似文献

The article examines the relationship between selective traditions in geographical education, what middle school teachers choose to emphasise in geographical education, and student achievement. The study, conducted in Sweden, is based on observations made by students in teacher training programmes, interviews with teachers, and analyses of a test administered to middle school students. It shows that selective traditions in geographical education are strong, resulting in a focus on country-related knowledge and map-reading skills. Both teachers and students seem unclear about what other subject-specific skills geography teaching provides. Furthermore, students have difficulty achieving a high level of geographic reasoning. The authors argue that a subject-specific language in geography is important in both teaching and assessment. They stress that students need more practice in geographic reasoning, since this is required by the new curriculum and in the national test in geography for Year 6 (i.e. pupils in the age range 12–13 years). The study adds to earlier research by highlighting Swedish middle school teaching, which is a neglected field within curriculum studies, and by using a combination of methods to analyse the impact of selective traditions.  相似文献

Clout, H. D. 1974. Agricultural plot consolidation in the Auvergne region of Central France. Norsk geografisk Tidsskr. 28, 181–194.

Plot consolidation has made great progress in the Paris Basin and has accentuated the agricultural contrast between northern innovation and southern backwardness. The Auvergne contains a wide range of agrarian structures, with environmental conditions being most favourable for farming in the lowland Limagnes. Detailed examination of Puy-de-Dôme département shows that most of the Limagnes have been consolidated, but little has been done in the uplands, which require other forms of structural change, including enlargement and re-afforestation. Plot consolidation is not a revolutionizing process since it cannot change land ownership, which is the ultimate constraint on its success.  相似文献

Recent studies focused on Canadian metropolitan areas suggest that growing income inequality underlies problems of housing affordability for low- and moderate-income earners. This article investigates how unprecedented commodity-led economic growth between 1991 and 2011 has impacted housing affordability in five resource-driven agglomerations in Canada. Housing affordability is analyzed across income quintiles, looking at income, housing costs, tenure, housing quality, and housing debt. Using Statistics Canada Census microdata, we find that low- to mid-income earners faced the fastest relative increase in housing costs between 1991 and 2011, combined with small income gains over that period. Homeowners in the lowest income quintiles seem particularly vulnerable when carrying a mortgage, with economic volatility engendering greater risks of housing market contractions or job loss over time. Whereas previous literature has emphasized housing vulnerability in large metropolitan areas, the results highlight new patterns of risk-laden housing-related vulnerability in resource-driven regions in Canada.  相似文献

In this article, we first replicate and then adapt an existing index of social vulnerability to hazard developed for the United States to a non-U.S. context. We construct indexes for Norwegian municipalities, describe the adjustment process, and compare the replicated and adapted assessments. Our results indicate only a moderate correlation between the replicated and adapted vulnerability indexes and for several municipalities the difference between the indexes is considerable. This demonstrates that context matters and that indexes of vulnerability need to be adapted rather than replicated. To facilitate such adaption processes, we identify three types of accommodation: conceptual, technical, and geographic.  相似文献

Abstract

Between 1990 and 2000 the U.S. Hispanic population increased by 14 million, which is the largest decadal population rise in United States history. This increase was not spread evenly throughout the United States, nor was it isolated to locations that already had large Hispanic populations. On the contrary, areas that previously had a relatively small Hispanic population experienced large percentage increases. In this article the regional variability in Hispanic population growth is explored, along with an emphasis on the economic pull factors driving those demographic changes. This analysis illustrates how restructuring in the meatpacking industry, and the associated economic impacts, have created a dependence on a low wage, illegal labor force that has shaped the recent demographic trend in the South and Midwest.  相似文献

The antiquated and undemocratic rules operating in the United Nations Security Council do not reflect and serve today’s integrated global society, nor does the institution adequately represent the diversity of member states. Despite General Assembly discussions that have lasted a quarter-century, no result has materialized on the expansion issue. The author concludes that regional rivalries, the veto, the onerous Charter amendment process, and the failure to devise a truly representative model are responsible for the lack of progress. A model with eighteen rotating seats, based on population, area, and regional position, and four elected seats deserves consideration as an alternative. Key Words: metageography, political geography, population and area ratings, United Nations Security Council.  相似文献

As they increase in popularity, social media are regarded as important sources of information on geographical phenomena. Studies have also shown that people rely on social media to communicate during disasters and emergency situation, and that the exchanged messages can be used to get an insight into the situation. Spatial data mining techniques are one way to extract relevant information from social media. In this article, our aim is to contribute to this field by investigating how graph clustering can be applied to support the detection of geo-located communities in Twitter in disaster situations. For this purpose, we have enhanced the fast-greedy optimization of modularity (FGM) clustering algorithm with semantic similarity so that it can deal with the complex social graphs extracted from Twitter. Then, we have coupled the enhanced FGM with the varied density-based spatial clustering of applications with noise spatial clustering algorithm to obtain spatial clusters at different temporal snapshots. The method was experimented with a case study on typhoon Haiyan in the Philippines, and Twitter’s different interaction modes were compared to create the graph of users and to detect communities. The experiments show that communities that are relevant to identify areas where disaster-related incidents were reported can be extracted, and that the enhanced algorithm outperforms the generic one in this task.  相似文献

Changing racial/ethnic diversity along with economic growth have also drawn renewed public attention to growing income inequality and lack of economic well-being in the American society. This paper investigates one element of contemporary inequality – the income divide between the richest and the poorest population groups in the metropolises of the U.S. Southeast. This paper examines income divide across southern U.S. metropolises in 2000 and 2014, their change during 2000–2014, their variation across major races/ethnicities, and their relationships with important metropolitan characteristics such as diversity, intermixing, socio-economic status and built-environment attributes. Cartographic, ranking/matrix, and correlations analyses suggest that the largest, most diverse, most segregated, and those with a greater presence of better educated are the most income divided metropolises, whereas the small-to-mid-sized metropolises, with lesser educated population are less divided. The income divide has increased during 2000–2014 in a majority of these metropolises, and for all races/ethnicities, even though Whites and Asians are relatively better-off compared to overall population whereas Blacks and Hispanics lag behind.  相似文献

Web 2.0 has yielded a wealth of publicly available data, largely through the popularization of social media and the proliferation of user-generated content (UGC). Thus, the data void in social science research is diminishing as these new data sources are exploited. The discipline of geography, in particular, stands to benefit considerably from geotagged UGC or volunteered geographic information (VGI). In this article, we utilize a form of UGC—restaurant reviews—to evaluate the geography of Web 2.0 in Franklin County, Ohio. We find that restaurant reviews are largely concentrated in relatively few areas of the city, indicating that the impacts of Web 2.0 have not touched down evenly within the central county of the Columbus metropolitan statistical area. We argue that an intraurban digital divide is still apparent and might even be exacerbated by Web 2.0.  相似文献

Zhejiang Province, located in the Yangtze River Delta region, is representative of China's economically developed areas. It enjoys superior natural conditions and a long history of agriculture, and is a comprehensive agricultural area with integrated development of agriculture, forestry, animal husbandry and fishery. It has nurtured the farming culture represented by Hemudu culture and Liangzhu culture, which have given rise to numerous precious Agricultural Heritage Systems. At present, Zhejiang Province has three of the world’s Globally Important Agricultural Heritage Systems (GIAHS) and 12 China Nationally Important Agricultural Heritage Systems (China-NIAHS), so it not only has the largest number of heritages in China, but it has also attained remarkable achievements in heritage conservation. Taking Zhejiang Province as an example in combination with the rural revitalization strategy, this paper summarizes the achievements in the protection of Important Agricultural Heritage Systems (IAHS) in Zhejiang Province during the past 15 years from the aspects of increasing farmers’ income, cultural Inheritance and industrial upgrading, as well as the conservation experiences in government promotion, community initiative, enterprise participation, technology driving and social linkage. Further, in view of the problems that exist in the current heritage protection,such as imperfect management of heritage sites, low participation of community residents, lack of special protection funds, and imperfect provincial management system,the following countermeasures and suggestions are put forward: (1) Improve the management mechanism for the conservation and development of Agricultural Heritage Systems; (2) Develop regional public branding of agricultural products in Agricultural Heritage System sites; (3) Increase the Agricultural Heritage System science education as well as cultural and creative product development; (4) Carry out the evaluation and recognition of IAHS at the provincial level; and (5) Provide substantial support and input to the conservation and utilization of IAHS. This study can provide some guidance for the conservation of IAHS in Zhejiang Province and it provides important reference for IAHS in the economically developed areas in China.  相似文献
