The study focuses on the analysis of manufacturing industry in Saudi Arabia by examining development, structure and spatial distribution. The analysis has shown that Saudi manufacturing is basically of recent development and is highly capital- and energy-intensive, particularly the hydrocarbon-based groups. Perhaps the most conspicuous weakness of Saudi industrialization is the almost total dependence on expatriate labour. Foreign capital and expertise share in the building and development of the industrial sector by providing technical, managerial, and marketing skills. Saudi industry is heavily subsidized by the government, and the public sector plays a commanding role in industrial development. Large-scale basic industries are owned and run by the government, while light manufacturing of the import-substitution type is dominated by the private sector. One of the main characteristics of manufacturing industry is that it is scantily diversified, modestly concentrated and remarkably linked geographically but not functionally or structurally. Although the authorities are exerting tremendous efforts to achieve a regional balance in industrial development, Saudi manufacturing industry is significantly polarized, urban-oriented and highly associated with the major axes of population scatter. Like all developing countries beginning to industrialize, Saudi manufacturing industry faces certain problems which have to be resolved so as to lay the foundations for a sound and prosperous industrial future. The paper goes on to indicate problems and to suggest solutions.  相似文献

The Cascadia subduction zone fault lies just off the Pacific coast of the USA and Canada. Although this fault has been seismically inactive over the written history of the Cascadia region, it has the potential to produce catastrophic earthquakes and tsunamis. A variety of dating methods have been used to show that the most recent Cascadia earthquake occurred in 1700. Among these methods is an informal analysis of oral traditions handed down by Native American peoples that appear to refer to a major earthquake in this region. A central difficulty in analyzing these narratives quantitatively is their use of a generation and other qualitative measures of time that have no fixed lengths. Here, these narratives are analyzed under an explicit statistical model of the lengths of these measures. The results raise a question about the previous conclusion that these narratives all refer to the most recent Cascadia earthquake.

According to many researchers, the use of inter-firm collaborative practices as a new industrial production strategy is increasing as a response to industrial restructuring and changing environmental conditions. The adoption of these practices is thought to be particularly critical for small firms, and consequently governments in most industrialized countries have designed specific policies aimed at encouraging inter-firm relationships. The few empirical studies have focused on the experiences of model industrial districts to support claims about the ubiquity of collaborative relations. The present study of a more typical urban area examines three interrelated issues: the incidence of inter-firm relations, the motivations and forms of collaboration, and the influence of public policies on inter-firm relationships. Information was collected from 191 small electronics firms in the Greater Toronto Area (GTA). The results suggest that inter-firm collaboration is moderately common but not the norm. The incidence of collaborative activities is likely to increase with company size. While motives for inter-firm activities vary slightly with firm size, the nature and forms of agreements are largely similar among various sizes of firms. The paper notes that public policies and programs within the GTA have not had the desired impact of creating cooperative attitudes among small electronics firms. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

For nearly twenty years the South African government has engaged in a policy of attracting industry to its internal ‘black states’, the bantustans. This case study of the Ciskei bantustan seeks to show that this politically motivated programme has been costly and ineffectual, both as regards its political objectives and economic development, however broadly defined.  相似文献

Historically, political struggles to define the geographical scale at which labour relations and collective bargaining will be conducted have been of crucial significance to the labour movement. Today, workers and their unions face very difficult challenges. In many manufacturing industries changes in the organizational structure of production at different geographical scales have undermined the effectiveness of the organizing and collective bargaining strategies associated with traditional industrial unionism. This paper focuses on collective bargaining strategies developed by North American autoworkers’ unions to respond to the extensive restructuring of the automotive industry that took place during the 1990s. These strategies include innovations in the structure and content of collective bargaining and efforts to redefine the scale at which collective bargaining takes place. Following a brief discussion of the challenge posed by the integration of Mexico into a continent-wide production system, the analysis focuses on the strategies devised by the Canadian Auto Workers (CAW) union during the 1996 and 1999 rounds of collective bargaining to address issues raised by outsourcing and modular manufacturing. With outsourcing, the automakers are not so much eliminating jobs as they are deciding who gets to do them, at what price, and under what working conditions. With modular manufacturing, the organizational boundaries between firms are blurring and the terms and conditions of work in one firm arguably are becoming dependent upon management decisions made in another firm. The CAW’s response has been to develop new collective bargaining strategies including the concepts of ‘work ownership’ and ‘satellite bargaining’ which involves redefining the traditional geographical extent of the bargaining unit. While the empirical focus is on the North American automobile industry, the general issues related to the re-scaling of production, and especially outsourcing and modular manufacturing, are common across a range of manufacturing industries.  相似文献

The position of the United Kingdom as a host country for foreign direct investment in manufacturing is examined in the European context. Several trends are identified which suggest that the United Kingdom's relative position is changing. In particular, the balance of United States manufacturing investment has been shifting away from the United Kingdom and towards mainland Europe while the United Kingdom's membership of the EEC enables European countries to serve the United Kingdom market by exporting rather than by direct investment. As yet, the volume of Japanese investment in United Kingdom and European manufacturing is small. In the competition between nations for internationally mobile investment. Ireland has captured a good deal of new manufacturing investment, some of which may have been ‘diverted’ from the United Kingdom. The apparent decline in the attractiveness of the United Kingdom as a host country for foreign manufacturing investment could have serious consequences for employment in the peripheral regions of the United Kingdom particularly in the light of developments in the organization of multinational enterprise and the impending enlargement of the EEC.  相似文献

The Moon: A Taylor perspective   总被引:1,自引:0,他引:1  
We address several current lunar problems. The data suggest that the Moon likely possesses an Fe-rich metallic core a few percent of lunar volume, although definitive proof is lacking. Refractory elements appear to be enriched relative both to the composition of the primordial solar nebula (CI) and the Earth. Very volatile elements appear to be depleted uniformly at high levels. We adopt the single-impact hypothesis for lunar origin, which formed a high-temperature silicate vapor disk, mostly of metal-poor silicate material from an impactor (Theia) that was already depleted in volatiles. We speculate that the curious lunar bulk-composition resulted from condensation from high-temperature vapor at around a few Earth radii. This could produce an enriched refractory-element composition that cut off below 1000 K, producing a uniform depletion in very volatile elements.  相似文献

This article focuses on the Holocene tree line (Pinus sylvestris) and climate change in the Swedish Scandes. A composite of three previously independently published data sets of megafossil tree remains (trunks, stumps and roots) from sites above today's tree line is analysed. Calibration of ages, adjustment for glacio-isostatic land uplift and a larger sample provide new and more conclusive insights. The tree-line altitude peaked about 11 200 cal. yr BP, 425 m higher than the position about a century ago, when it was at its Holocene low. At the millennial-centennial scale, tree-line retraction has been a smooth process, following a linear trend, which largely conforms to the Milankovitch model of orbital forcing of summer temperature evolution. Shorter excursions from this trend cannot be ruled out, as these are beyond the resolution of the analytical approach. During the earliest Holocene, summers may have been about 2.5°C warmer than by the late-19th century. Projection of the 20th-century maximum tree-line rise by 150-190 m upon the entire Holocene tree-line chronology indicates that present-day tree lines may be higher than ever during the past 5000 or even 7000 years. Indirectly, this might reflect an anomalous modern climatic regime for which there is supporting evidence from retreating mountain glaciers and recent evolution of the alpine plant cover and its zonation patterns. With this background, the evolution of the tree-line ecotone in the case of continued warming is considered. Pine is likely to regain the dominant position held in the early Holocene. Its tree line may shift at least 400 m above its present position. Small outlier stands of mountain birch will establish in sheltered, moderately snow-rich habitats high above the new pine tree line, but an overall alpine character of the landscape will prevail above the tree line of pine. Exotic tree species, mainly belonging to the genus Pinus may profit from a new climatic regime and establish in the tree-line ecotone.  相似文献

Isotopic data have established that, compared to estimated bulk earth abundances, the sources of oceanic basaltic lavas have been depleted in large ion lithophile elements for at least several billions of years. Various data on the Tertiary-Mesozoic Gorgona komatiite and Cretaceous Oka carbonatite show that those rocks also sample depleted mantle sources. This information is used by analogy to compare Pb isotopic data from 2.6 billion year old komatiite and carbonatite from the Suomussalmi belt of eastern Finland and Munro Township, Ontario that are with associated granitic rocks and ores that should contain marked crustal components. Within experimental error no differences are detected in the isotopic composition of initial Pb in either of the rock suites. These observations agree closely with Sr and Nd data from other laboratories showing that depleted mantle could not have originated in those areas more than a few tenths of billions of years before the rocks were emplaced. On a world-wide basis the Pb isotope data are consistent with production of depleted mantle by continuous differentiation processes acting over approximately the past 3 billion years. The data show that Pb evolution is more complex than the simpler models derived from the Rb-Sr and Sm-Nd systems. The nature of the complexity is still poorly understood.  相似文献

Landslides represent a major threat to human life, property and the environment. Landslide hazard and risk assessments seek to inform the policy and practice of landslide hazard risk management, for example, by identifying high-risk areas so that appropriate policy and private actions could be taken in terms of preventive and mitigative measures. We examine whether a decentralized risk assessment system leads to better assessment outcomes compared to a centralized risk assessment system. The paper is based on a comparative study of two countries??India and Italy??and their responses to landslide risk. Our results indicate a causal relationship between decentralization and three outcomes. First, decentralization appears to be conducive to the more rapid and more complete assessment of risks in local places, through mapping at an appropriate scale. Second, decentralization appears to foster greater and more transparent communication of risk assessment products, such as maps. Third, decentralization appears to lead to a more open, and at times contentious, public discourse over how to interpret and respond to the information contained in the risk assessments and maps. However, in practice, decentralization faces serious institutional resistance. Our analysis does not preclude other risk assessment outcomes or competing explanations for differences in risk assessment and management outcomes. Rather, it provides an understanding of the direction in which the institutional change may be driven for bringing about more effective risk assessments and their use.  相似文献

As Nigeria experiences the major thrust of urban growth, urban poverty has become the most intractable phenomenon attracting the attention of concerned observers. Because Calabar Municipality lacks solid economic base it cannot easily absorb its burgeoning population into productive medium and high income occupations. A wide range of interrelated variables, including the people's annual income, their educational level, occupational distribution, residential status and even psychological factors, explain the structure of poverty in Calabar. As a result the poor in Calabar are seen to fall within a wide spectrum of deprivation, ranging from the poor of hope who are capable of moving on their own across the poverty line, to the hopeless poor who require assistance for survival. Thus the study suggests that since a mix lot of factors are involved in the structure of urban poverty the phenomenon calls for a systems approach which takes into consideration the interacting characteristics of the diverse parameters of the whole urban system, in the formulation of anti-poverty measures. Admittedly, any war against poverty in this city is destined to be one of the longest wars in human history. However, it is possible to substantially reduce the yawning gap between the rich and the poor which is the crux of the problem facing policymakers in this city.  相似文献

This paper highlights the importance of analysis of the microgeographies of occupation, and the spatially-differentiated means that the Israeli Occupation Forces use to maintain the occupation and create spaces of graduated incarceration for Palestinians. Using the examples of the hinterlands of Qalqiliyah and the old city of Al-Khalil (Hebron) in the occupied West Bank, this paper exposes the microgeographical differentiation the occupation mobilizes in its attempt to enact a panoptic sovereignty over the population, in the process of dispossession. This study challenges geopolitical formations of the state as primary actor, and focuses instead on narratives of Palestinians describing their own experiences of occupation by a hostile state. By relying on popular media, semi-structured interviews, and participant observation, this paper seeks to incorporate a Palestinian vision of life under occupation to challenge traditional geopolitical visions of the Palestinian Israeli conflict, in effect creating a subaltern geopolitical narrative.  相似文献

The challenge of peripheral ports: an Asian perspective   总被引:3,自引:0,他引:3  
The growth of ports peripheral to the dominant container hubs has been well documented in North America and Europe, and has led to the elaboration of several theoretical models. This paper applies these models to the situation in South East Asia where much of the growth in containerisation is taking place. While confirming the emergence of several peripheral ports that are mounting challenges to the major hubs, we demonstrate that the factors behind the challenges are different to those postulated in the literature. Issues of governance arising out of the complex restructuring of the global ports industry are singled out. We suggest that a new geography of container terminals based on management and operational strategies of private and public bodies involved in the port industry needs to be fashioned.  相似文献
