The dominating form of analysis in the transport sector is cost–benefit analysis (CBA). This study investigates the purpose and use of an alternative analysis intended to complement CBA in the Swedish high-speed rail project. According to CBA calculations, the project is heavily unprofitable. While some politicians called for project termination, the project leadership launched an alternative benefit analysis that calculated only benefits (disregarding costs). This was intended to be a basis for decision making on station localization and financing agreements, but it was quickly downplayed due to its methodological inconsistencies. However, the project leadership still used the identified benefits opportunistically as a counterweight to the negative CBA results. They also engaged local-level civil servants and politicians in making the reports. This built political momentum and made the local-level civil servants and politicians adopt the mindset of the project. This study shows how a methodologically flawed analysis is used for political manoeuvring. From a scientific CBA perspective, this is alarming, but from a political perspective it is not surprising. The findings echo earlier research showing that analysis for decision making is often used for political purposes. The results suggest that future research should consider how opportunism in alternative benefit analysis can be limited.  相似文献

This paper estimates China’s future population and labour force by developing a novel forecasting model for population. It combines information about age-specific parameters on fertility and mortality for both rural and urban areas using information about rural–urban migration and the transformation of rural areas into urban ones. This model takes into account the effects of urbanisation on changes in the age structure of the Chinese population; and provides separate projections on the rural and urban populations. Our findings show that (i) the shares of people aged 65 and over, in China’s rural and urban populations, will double between 2010 and 2030; this implies that the ageing problem in rural areas will continue to be more serious than in urban areas; (ii) the rural labour force will shrink by 45 per cent, between 2010 and 2030, while the urban labour force will grow by 34 per cent; and (iii) China’s urbanisation rate will increase to 71 per cent by 2030.  相似文献

The Homo erectus cranium found at Gongwangling, near Lantian, China, and dated to ≈1.2 ma BP has been analyzed with respect to its evolutionary position. However, the remains, and especially the internal and external surfaces of the neurocranium, present a series of marked abnormalities. These irregularities consist principally of a pronounced cresting and scalloping of the external surface of the frontal bone and anterior parietal bone and a similar alteration of the internal surface of a mid transverse section of parietal bone that connects with the fossilization break across the anterior parietal bone. There is no obvious exposure of diploë on the surfaces. Woo (Vertebrata PalAsiatica 10:1–16, 1966) briefly ascribed these abnormalities to postmortem erosion, and Caspari (Am. J. Phys. Anthropol. 102:565–568, 1997) has attributed the irregularities of the right supraorbital torus to antemortem trauma. It has been suggested that the pervasive neurocranial alterations might be pathological. Computerized tomography (CT) analysis of the frontal and parietal bones revealed complete radiopacity of the anterior half of the fossil; it is possible to distinguish large frontal sinuses but other details, including in the area of the purported traumatic lesion, are invisible. However, in the posterior frontal bone and preserved portions of the parietal bone the diploë and tables are discernible. Externally on the frontoparietal section and internally on the transverse parietal piece, there are clear erosional lacunae in the associated table, combined with a thin layer of matrix which obscures the eroded diploë externally. The superficial irregularities are therefore due to postmortem taphonomic alterations of the bone and not pathological processes. In addition, it is apparent that the two pieces were embedded in the matrix at different angles, resulting in their differential erosion.  相似文献

The Pêcheurs cave is a unique example of a Middle Palaeolithic site with three kinds of accumulations: (1) ibex that died in a natural trap, (2) carnivores that died within the cavity, and, (3) a series of short-term occupations by humans who left a few artifacts and a hearth area. Biological patterns of ibex remains (skeletal parts, age) show a homogeneous structure, related to natural death inside the cave. The Chassezac valley is narrow and sinuous, bordered by steep cliffs occupied by well-adapted hoofed-species (Caprinae). Moreover, Les Pêcheurs is a shallow cave, pit-like, and in its deepest part (Sector 4) provided both man and animals with shelter. The presence of a fire place (in the middle of the sequence of Sector 4) firmly indicates the presence of an in situ occupation by a small group of hominids. According to the stratigraphical patterns and the analysis of the lithic assemblages, artifacts do not seem to have been introduced into sediments. The lithic assemblages (technically homogeneous) indicate that small mobile human groups inhabited a cave that offered, by virtue of its morphology, a natural shelter against the cold winds blowing in the Chassezac valley and the plateaus of the south-eastern borders of the Massif Central Mountains. The exploitation of biotopes such as this rocky area constitutes a specific case of human subsistence behavior and settlement strategy. The deepest layer is characterized by a lithic assemblage mostly made of local raw material (quartz) implying a low investment in lithic production. Few flakes made from non-local flints attest to the mobility of the human occupants who moved across these areas and perhaps found in the valleys, short-term refuge.  相似文献

This paper summarizes the theoretical insights drawn from a study of thirteen large–scale urban development projects (UDPs) in twelve European Union countries. The project focused on the way in which globalization and liberalization articulate with the emergence of new forms of governance, on the formation of a new scalar gestalt of governing and on the relationship between large–scale urban development and political, social and economic power relations in the city. Among the most important conclusions, we found that: ?Large–scale UDPs have increasingly been used as a vehicle to establish exceptionality measures in planning and policy procedures. This is part of a neoliberal “New Urban Policy” approach and its selective “middle — and upper–class” democracy. It is associated with new forms of “governing” urban interventions, characterized by less democratic and more elite–driven priorities. ?Local democratic participation mechanisms are not respected or are applied in a very “formalist” way, resulting in a new choreography of elite power. However, grassroots movements occasionally manage to turn the course of events in favor of local participation and of modest social returns for deprived social groups. ?The UDPs are poorly integrated at best into the wider urban process and planning system. As a consequence, their impact on a city as a whole and on the areas where the projects are located remains ambiguous. ?Most UDPs accentuate socioeconomic polarization through the working of real–estate markets (price rises and displacement of social or low–income housing), changes in the priorities of public budgets that are increasingly redirected from social objectives to investments in the built environment and the restructuring of the labor market. ?The UDPs reflect and embody a series of processes that are associated with changing spatial scales of governance; these changes, in turn, reflect a shifting geometry of power in the governing of urbanization.  相似文献

Environmental change has a human dimension, and has had so for at least the last 10 000 years. The prehistoric impact of people on the Arctic landscape has occasionally left visible traces, such as house and field structures. More often than not, however, the only evidence available is at the microscopic or geochemical level, such as fossil insect and seed assemblages or changes in the physical and chemical properties of soils and sediments. These records are the subject of SEAD, a multidisciplinary database and software project currently underway at Umeå University, Sweden, which aims to create an online database and set of tools for investigating these traces, as part of an international research infrastructure for palaeoecology and environmental archaeology.  相似文献

Cardinal Richelieu's commercial projects have long been seenas a part of his early efforts to reform the French state. Thispaper argues that Richelieu's commercial activity can more profitablybe viewed in the context of his thinking about relations betweenFrance and its neighbours and of a pan-European movement toreconsider the connections among commerce, governance and sovereigntyspawned by the Dutch war with Spain. Specifically, it examinesRichelieu's relations with the Dutch jurist Hugo Grotius. In1626 the cardinal attempted to hire Grotius as a commercialexpert, consulting with him on several occasions. Although Grotiusdeclined, the cardinal was deeply influenced by Grotius’arguments about the freedom of commerce and trade. Richelieuadapted these arguments to suit French needs and his own Catholicvision of the state.  相似文献

There have been a number of important efforts to map out the languages of Iran, but until now no language atlas, or even a comprehensive and detailed country-level language map, has been produced. One of the recent initiatives which aims to fill this gap is the online Atlas of the Languages of Iran (ALI) (http://iranatlas.net). This article delineates objectives of the ALI research programme, atlas architecture, research methodology, and preliminary results that have been generated. Specific topics of interest are the structure and content of the linguistic data questionnaire; the handling of contrasting perspectives about the status of “languages” and “dialects” through a flexible multi-dimensional classification web; and the role of ongoing comparisons between language distribution assessments and hard linguistic data.  相似文献
