This work concerns the stability of unreinforced masonry slender circular cross-sectional columns subjected to their own weight and eccentric vertical load. Cantilever columns are examined, considering that the material has infinitely linear elastic behavior in compression and has no tensile strength. For the analysis, an existing numerical model and solution procedure developed for the stability analysis of masonry elements with rectangular cross-section are utilized and adapted to the circular columns. For the instability of the columns, an appropriate criterion that relates the top lateral deflection to the intensity of the applied eccentric vertical load is employed. By considering a reference column, critical buckling load is obtained, behavior of the column interpreted and efficiency of the numerical model emphasized. Performing a nonlinear buckling analysis using a general purpose software on this reference column, obtained results are compared with those of the adapted procedure of the present study. Implementing parametric analyses on reference column, effects of the column slenderness, eccentricity of vertical load, elastic modulus, and self-weight on the buckling load are investigated. Presented calculation procedure provides a useful tool in order to calculate the critical loads or to check the stability of masonry circular columns.  相似文献

Cities are considered to be the major drivers of the global economy for many reasons, including their creative and innovative potential in generating sustainable economic growth. Istanbul is one of the global cities searching for a long-term growth strategy. This paper starts with a modest effort of composing an index to be used in the evaluation of the creative potential of cities. Our proposed index, “global creative index”, consists of five main criteria: (1) creativeness, (2) innovativeness, (3) intellectual development, (4) global network connectivity and (5) world cityness emphasizing multinational corporate economy, international division of labour and high intensity of producer and financial services. The use of the index is illustrated through the comparison of nine cities: Hong Kong, Istanbul, London, Los Angeles, Moscow, New York, Shanghai, Singapore and Toronto. The analysis of these nine cities shows that Istanbul is building an innovation environment, but it still lacks research and development infrastructure, technical support and investment in higher education. This comparison offers guidelines for policy-makers to sketch the growth of Istanbul along the lines of creativity and innovativeness.  相似文献

The paper investigates the patterns of technology and knowledge of the regions. The first aim of the paper is to determine cluster templates at the national level. The second aim of the paper is to investigate the technology and knowledge composition of the regional highpoint clusters. The paper identifies patterns of industrial linkages to define cluster templates and regional highpoints. The second part uncovers regional distributions of technology and knowledge. The data comes from Turkey’s 2012 input–output table. The location quotients use industrial employment statistics from the Turkish Statistical Institute. The technological and knowledge intensity classification follows Eurostat. The findings reveal 10 cluster templates in Turkey. Spatial distribution of the highpoint clusters reveals that most regions contain highpoint clusters with low technology and low knowledge-intensive sectors. The results reveal that highpoint clusters in Turkey’s regions contain industries whose technologies do not demand high skills, knowledge and sophistication. Limited existence of high-tech industries and low knowledge intensity in Turkey’s industry composition is a limiting factor for transition to high value-added manufacturing. Special emphasis should be directed towards constructing regional advantage, given the current levels of technology and knowledge intensity.  相似文献

Abstract

This study is an analysis of the narratives of Turkish Cypriot women in the north of Cyprus who were displaced during the ethnic conflict between the 1950s and 1974. We have conducted 21 interviews with Turkish Cypriot women who were living in different parts of Northern Cyprus. We used oral history, both as a method and as an epistemological stance to re-phrase the near past of Cyprus and the Cyprus issue from the perspective of gender/women’s studies. The study follows the traces of modernity, patriarchy, and nationalism in women’s narratives, about the place, home, belonging and homelessness. The narratives describe Turkish Cypriot women’s experiences of being a woman in conflict and displacement (‘göçmen olmak’ in daily talk in Turkish) making a home out of a house and undertaking daily routines for their families. The study also reveals that ethnic conflict and displacement have empowered women to a certain degree.  相似文献

Within the Near Eastern research canon, the transition to more sedentary lifestyles during the Neolithic is often framed as an economic necessity, linked to plant and animal domestication, climatic change and population stress. In such a framework, an increasingly complex social structure, arising in response to the increasingly complex relations of agricultural production, is presumed. For example, some researchers would argue that feasting-based rituals became an arena of social control and an increasingly complex society began to emerge around ritual leadership and monumental ritual architecture. Yet the research projects conducted at many Near Eastern sites indicate neither that sedentism can be directly linked to the requirements of agriculture, nor that the presence of monumental architecture can be successfully associated with social control based on unequal redistribution of agricultural surplus. While ritual activity appears to be central during the Neolithic, two important questions remain to be explored: (1) what exactly did the rituals control, given that the societies under consideration are commonly perceived to have an ‘egalitarian’ ethos?; and (2) what happened to the ritual control in the second half of the PPNB, when ritual architecture completely disappears from the archaeological record at a time of increased reliance on agriculture? Through a critical review of the use of terms like ‘sedentism’, ‘egalitarianism’ and ‘ritual’, I argue that the architecture of the Early Neolithic is related to the management of social relationships through symbolic place-making activities. Based on a comparative review of burial activity, building continuity and the use of symbolic imagery, I examine the symbolic construction of some of the earliest examples of long-term occupational focus in southeast Anatolia, such as Hallan Çemi, Demirköy, Körtik Tepe, Hasankeyf Höyük, Gusir Höyük, Göbekli Tepe, Çayönü and Neval? Çori, in an attempt to understand the social factors behind the emergence and demise of Early Neolithic monumental architecture. The evidence from the above-mentioned sites suggests that Early Neolithic place-making reflects community formation at a variety of scales, at the center of which lay the continuous reinvention of kinship concepts. While some sites, with concentrations of burials, may have become the locus for construction of more intimate local place-based networks, other sites, such as Göbekli Tepe, may have integrated the extended networks. Arguably, the formation of large scale networks during the PPNA posed a threat to local groups. Thus, a focus on local group formation and close control of social exchanges may have begun during the early PPNB, and the places such as Göbekli Tepe may have fallen out of use during this process. In the context of the symbolism and figurine evidence, I further argue that sex and gender may have become important issues, both in the formation of place-communities during the late PPNA—early PPNB, and in the emergence of autonomous households during the later PPNB.  相似文献

High tourism growth in single-asset tourism cities is often associated with a standardization of supply of products and services by tourism entrepreneurs. However, and in contrast to this common-sense view, tourism growth in specific urban tourism milieus in the ‘sun-sea-sand’ tourism city of Antalya has stimulated tourism entrepreneurs to differentiate their products. Contrary to most economic-geography literature on spatial clusters, evolutionary economic geographers argue that inter-industry relations of (un)related variety are crucial in inter-firm differentiation. The aim of the paper is to define the factors that influence tourism-firm differentiation in the single-asset tourism city of Antalya. The empirical research is theoretically informed by evolutionary economic-geography literature, and pays much attention to the role different urban sub-milieus play in tourism-firm differentiation. It is the first research on the relation between (un)related variety and tourism-firm differentiation in tourism studies. The empirical research is based on primary data collected by a firm-level survey (hotels, restaurants, jewellery- and retail-trade firms) in the city of Antalya. The factors that influence tourism-firm differentiation are explored by using quantitative methods of analysis (an econometric logit-regression model and a correspondence analysis). The main result of the empirical research is that investments in firms in related sectors, in our case jewellery companies and hotels, are positively and significantly related to tourism-firm differentiation. In addition, the location tourism firms in areas visited by a mix of consumers (tourists and locals) also is positively and significantly related to inter-firm differentiation whereas urban milieus visited by locals only have a negative effect.  相似文献

Investment is an important decision for economic development, balanced growth and public welfare. There are many factors influencing investment. Thus, investment must be evaluated with multidimensional methods. Using taxonomy and principal component analysis this study attempts to determine appropriate investment areas in planned provinces in the Black Sea Region. Analyses were based on a number of demographic, economic, health, education, employment and cultural indicators. Results indicated that provinces were grouped into four clusters. Gümü?hane and Bayburt were determined to have the highest priority for investment in the manufacturing industry.  相似文献

Changes in resource use over time can provide insight into technological choice and the extent of long-term stability in cultural practices. In this paper we re-evaluate the evidence for a marked demographic shift at the inception of the Early Iron Age at Troy by applying a robust macroscale analysis of changing ceramic resource use over the Late Bronze and Iron Age. We use a combination of new and legacy analytical datasets (NAA and XRF), from excavated ceramics, to evaluate the potential compositional range of local resources (based on comparisons with sediments from within a 10 km site radius). Results show a clear distinction between sediment-defined local and non-local ceramic compositional groups. Two discrete local ceramic resources have been previously identified and we confirm a third local resource for a major class of EIA handmade wares and cooking pots. This third source appears to derive from a residual resource on the Troy peninsula (rather than adjacent alluvial valleys). The presence of a group of large and heavy pithoi among the non-local groups raises questions about their regional or maritime origin.  相似文献
