The purpose of this paper is to test the differential urbanisation theory for the Turkish case during the 42 years between 1955–97. The theory is first tested for the country as a whole, and subsequently for each of its three major regions with differing development levels. The findings for Turkey, in general, are consistent with the theory of differential urbanisation. The country and all its regions are found to be at the ‘early medium city’ stage (i.e. the first phase of polarisation reversal). The timing of the stages in three regions was consistent with their respective level of development. The special characteristics of the Turkish case and their effects are discussed. 相似文献

Echinochloa was an important prehistoric food crop of early agriculture in Asia. Macro-remains can be used to identify Echinochloa. However, when few macro-remains are available, phytolith analysis can be performed. In this study, we examined the phytolith morphology of the glumes, lemmas, and paleas from the inflorescence bracts of nine Echinochloa species from different regions of China and obtained diagnostic, morphological, and morphometric characteristics for Echinochloa. Phytoliths in Echinochloa are different from those in most known crops except those in Setaria italica and Panicum miliaceum. We found the following two diagnostic features within an epidermal silica layer that can be used to distinguish Echinochloa sp. from S. italica and P. miliaceum: (1) the β-type undulated patterns with constricted top of the undulation amplitude and (2) the discriminant functions based on the morphometric data of the β-type undulated patterns, which suggested that 94.9 % of the cross-validated data were correctly classified into Echinochloa, S. italica, and P. miliaceum. Thus, we established the phytolith identification criteria for Echinochloa; this could have important implications in plant taxonomy, archaeobotany, and plant domestication. 相似文献

ABSTRACTThis article explores the predictors of children’s satisfaction with mass housing, which were built in the context of squatter housing regeneration. The results are based on a survey of 186 nine-to-twelve-year-old children living in four mass housing sites in Ankara, Turkey. They show the specific features of the dwelling and neighborhood that were critical in predicting children’s residential satisfaction: dwelling location and size; appearance of interior design elements provided by the authority; views from the windows; proximity, quality and quantity of public open spaces; quantity of greenery; building types in the mass housing estate; external appearance of buildings in the neighborhood; safety of street crossings; the continuity, width and comfort of sidewalks; the quality of municipal services; and the number of liked people in the neighborhood. These findings are important as they help planners and designers to consider and incorporate components that contribute to an improved residential satisfaction among children. 相似文献

This study assesses the spatio-temporal impact of vaccination efforts on Covid-19 incidence growth in Turkey. Incorporating geographical features of SARS-CoV-2 transmission, we adopt a spatial Susceptible–Infected–Recovered (SIR) model that serves as a guide of our empirical specification. Using provincial weekly panel data, we estimate a dynamic spatial autoregressive (SAR) model to elucidate the short- and the long-run impact of vaccination on Covid-19 incidence growth after controlling for temporal and spatio-temporal diffusion, testing capacity, social distancing behavior and unobserved space-varying confounders. Results show that vaccination growth reduces Covid-19 incidence growth rate directly and indirectly by creating a positive externality over space. The significant association between vaccination and Covid-19 incidence is robust to a host of spatial weight matrix specifications. Conspicuous spatial and temporal diffusion effects of Covid-19 incidence growth were found across all specifications: the former being a severer threat to the containment of the pandemic than the latter. 相似文献

This article discusses two aspects of heritage – entanglement and transformation – that became clear during a recent cultural heritage project in Yucatan, Mexico. Regarding entanglement, heritage becomes relevant only when coupled with other concerns, ranging from politics to livelihood to personal biographies. An unpredictable array of entanglements came into being during the project and these entanglements elevated the impact and visibility of local heritage to an unanticipated degree. Transformation refers to the claim that heritage is not frozen in the past. Instead, it is in motion and subject to change. The transformations of heritage discussed in this paper are examined from the perspective of a mobilities paradigm and understood, in part, as resulting from the experience of performing heritage for outsiders for the first time. In so far as the heritage project precipitated changes in identity, this paper explores what is meant by Maya identity and argues that it is a fluid construct that can be both anchored in the past and negotiated in the present. This perspective makes sense of an event in which contemporary people anchored their identity in a spectacular 1000-year-old ruin, but falls short of explaining the uneven recognition of smaller ruins. 相似文献

To resolve the dilemma among a shortage of high-end talents, low level of scientific research and a huge brain drain in western universities in China, we proposes a way out by building an intelligence-alliance innovation team—a new interregional and multiagent cooperation mode. We identify major disagreements that hamper a fruitful collaboration, and then analyze reasons of such poor coordination. Given diversified backgrounds and different preferences of intelligence-alliance innovation teams, we suggest multiagent group decision-making as a method of seeking task coordination for participants in conflict and their problem-solvers. Finally, a specific case is given to prove that this method can improve task coordination of intelligence-alliance innovation teams, and that holistic feedback coordination may be the best scheme of task coordination for intelligence-alliance innovation teams. 相似文献
