Most studies on the impact of China’s urbanization on local climate focus on developed coastal cities, with little attention paid to inland developing cities. In the present study, we selected three representative and neighboring developing cities (Nanchang, Jiujiang and De’an) in East China to examine, through comparative analyses, local climate changes in inland developing cities with varying sizes during the past 45 years, based on homogenized datasets (1967-2012) released by the National Ground Meteorological Station, taking local economic, demographic, etc. factors into account. Our findings are as follows: The speed of urbanization in these three inland developing cities is correlated to their respective status and sizes - the bigger the city, the faster the urbanization occurring in said city. The pace of the urbanization has a clear impact on the local temperature variability. For the past 45 years, the warming rate in Nanchang (large city) was approximately 0.27 /decade while that in Jiujiang (middle-size city) was approximately  0.23 /decade and that in De’an (small town) was approximately 0.20 /decade. The warming rate was observed to rise in line with city size. The number of high temperature days (HTDs) increased significantly in all three cities over the course of the past 45 years. During the period of 2003 to 2012, HTDs in Nanchang, Jiujiang and De’an increased by 9.8, 5.1 and 1.3 days, respectively, compared with the period of 1967-1976. The larger the city, the more significant the increase in HTDs was observed.

This paper focuses on the new approach studying variations in city size and the impact that the Silk Road had on the structure of cities, demonstrated through the study of economic aspects of the Bukhara oasis. We use archaeological data, compare the ancient economy to modern ones, use modern economic theory and methods to understand ancient society, and use what we have learned about the ancient economy to understand modern economies better. In sum, we explore the past through the present and the latter through the former. Our main finding is the generation of models able to answer to the city-size distribution in different territories, comparing them between the past and the present. This study first revealed that, through Zipf's Law, we found similarities between modern post-Industrial Revolution and medieval economics. Secondly, we also found that in ancient times the structure of the city was linked with the local economic demand. We have demonstrated this through the study of cities along the Silk Road.

The city of Johannesburg offers insights into urban governance and the interesting interplay between managing the pressures in a rapidly urbanizing context, with the political imperatives that are enduring challenges. The metropolitan municipality of Johannesburg (hereafter Johannesburg), as it is known today, represents one of the most diverse cities in the African continent. That urbanization, however, came up hard against the power of the past. Areas zoned by race had been carved into the landscape, with natural and manufactured boundaries to keep formerly white areas ‘safe’ from those zoned for other races. Highways, light industrial plant, rivers and streams, all combined to ensure the Johannesburg landscape are spatially disfigured, and precisely because it is built into the landscape, the impact of apartheid has proved remarkably durable. Urban growth is concentrated in Johannesburg’s townships and much of it is class driven: the middle class (of all races) is increasingly being found in cluster and complexes in the north Johannesburg, while poor and working-class African and coloured communities in particular are densifying in the south. The racial and spatial divisions of the city continue to pose fundamental challenges in terms of governance, fiscal management and spatially driven service delivery.

While statistical information on certain sectors of the British theatre is slowly becoming available – notably from the Arts Council and the Society of West End Theatre, as also from researchers in the Department of Arts Administration at the City University – few attempts have yet been made to draw useful conclusions from these figures, or to deduce how they might be helpful in terms of forward-planning and projections. In the following article. Paul Huntington examines the relationship between theatre revenue and total consumer expenditure, in the context of published figures which illustrate the changing national economic picture of the past decade. He examines not only the way in which these figures tend, naturally enough, to confirm certain expectations – for example, concerning the impact of tourism on the theatre – but also less expected findings, such as the relative upsurge in the fortunes of the regional theatres at a time of slump in the commercial sector of the West End.

Abstract Methods of reducing damage to the environment during construction, territorial planning, as well as measures for the improvement of territories aimed at its restoration are considered. The environmental problems of a large city and the assessment of the impact of urban planning objects on the environment have been studied in detail. The paper shows the need to revise the traditional principles of the formation of the urban framework. The paper rightly notes that if earlier much attention was paid to the formation of a technogenic framework of the city – a life support system consisting of transport and engineering infrastructures of the city, today the formation of the ecological framework of the city is becoming increasingly important. The high importance of the ecological (water-green) frame of the city as a system is determined by the fact that water bodies and adjacent territories, “green open” spaces can significantly affect the quality and state of the urban environment, and with careful thought-out, the formation of the ecological frame will help to ensure the integrity of the entire natural and technical urban system.

Based on historical-genetic and comparative research methods, the article reveals the determinants of formation and development of the city commemorative culture. This issue is relevant because of the increasing influence of the memory of the past on modern sociocultural processes. The scientific novelty of the article lies in the study of poorly studied issues of the impact of commemorative culture on the development of culture in general; the opportunities of regulating the nature and distribution of memorial forms; the factors determining the formation of the city commemorative culture in the context of the historical and sociocultural dynamics of applicable societies of the civilizations of the past and present. The article uses an integrated approach, which determines the interdisciplinary nature of scientific research, allowing analyzing the aspects of the origin, interpretation of the features of the history and existence of monuments in different cultures. There are provided examples of commemoration practices in the post-Soviet countries, including the Republic of Belarus. The article concludes that the content of commemorative culture is determined primarily by religious traditions and state priorities. The creation of monuments and places of memory is used as an agitation and manipulative resource making an emotional impact; as an ideological tool shaping the perception of history in accordance with the state ideology. Commemorative practices take on special significance during the formation of nations, influencing the subject’s identification with the nation, and the awareness of national solidity. In this case, the monument represents a universal form of embodying and conveying the national idea.

During the past three decades worldwide dairy policies have been implemented to promote the consumption of milk and milk products in urban areas and the production from rural areas close to big cities (Alderman et al., 1987). Bolivia and the city of Santa Cruz de la Sierra have been influenced by these worldwide directives and this current study examines the impact of policies on the demand and supply side of the sector, but with particular emphasis on smallholder milk producers and poor urban consumers. The current research is part of a multi-country study on the supply, demand and impact of dairy and other policies over a 10 to 15 year period (1985 to 2000) of the milk sectors of Santa Cruz, Bolivia; Nairobi, Kenya; and Kathmandu, Nepal.

Abstract The diversity of active surfaces in urban environment is an alarming element of microclimatic conditions at the time of positive energy balance. The accumulation of solar and reflected radiation are forming local climate - microclimate. Vegetation areas in the urban environment have the capability to eliminate extreme demostrations of local climate. The impact of transpiration causes an increase in the relative air humidity, reducing the effect of solar radiation. The result is the elimination of surface temperature in vegetation. The aim of this study is to evaluate the potentiality of accumulation of solar radiation depending on the vegetation structure and the type of surface in research areas A1-B1-C1, A2-B2-C2 between intervals 6:30 a.m.-12:30 p.m., 12:30 p.m.-9:30 p.m. The legwork ran in summer period June-August 2013 in residential area Chrenova 1 in the city Nitra.

Modern Ukrainian historical science faces many challenges that require a scientific solution. Exploring the life and work of famous people and the history of individual regions of Ukraine are among them. The end of 19th - the beginning of 20th centuries in the history of Ukraine is characterized by a general revolutionary exaltation that was caused by sharp contradictions, national oppression, political disenfranchisement of the population. It is a time when new creators of history enter the political scene.  Nowadays, the critical task is to rethink the role of the individual in history, to explore creative people, to fill the historical process with energetic, working people, to make this process anthropocentric. It is necessary not only to revive the forgotten names but to determine a place for each personality in the history of Ukraine. The article aims to show the features of the pre-revolutionary past of Kherson city from the perspective of Leonid Solovyov, indigenous inhabitant, engineer, the qualified worker of Kherson seaport and brilliant memoirist. In his memoirs, he described the city in pre-revolutionary times and showed the changes of Kherson during Soviet power. Memoirs (memories) are a special kind of written historical sources that reflect the author’s understanding of past reality and historical consciousness of the personality of their creator. They are about the past based mostly on a personal the memory of the author and his own impressions of those events in which he participated or which he watched by himself. In his memoirs, we see the dualistic nature of historical sources, because, on the one hand, they record information about the past and, therefore, it is its reflection. On the other hand, memoirs are part of the period in which they came on. Today Mr Solovyov’s memoirs are unexplored, and this article is the first attempt to show the role of this personality. Pre-revolutionary Kherson had a number of its features. It was a small, quiet, calm, provincial town. Mr Solovyov remembers the city since 1914. He was always interested in the history of his native city. The comparison of pre-revolutionary and Soviet Kherson from the perspective of an ordinary citizen of Kherson is particularly useful. Most of Kherson citizens worked as merchants, officials, entrepreneurs and small haggler. The workers were a minority, lived mainly in the suburbs and had their property, farm. It was a typical and traditional demonstration of the usual Ukrainian way of life. The result of long and hard work of Mr. Solovyov as an ethnographer is a significant number of photo albums, including “Kherson seaport”, “Flood in Kherson”, extracts from books, magazines, newspapers about ports of Kherson, Skadovsk, Khorly, and, of course, memoirs about his native city and the port which contains unvalued layer of interesting information about the history of our city. It is shown the role of the individual in history and the impact of circumstances and the environment in the formation of his worldview and future activities from Mr Solovyov example. It is the first time when the researcher is depicted as a citizen whose life was dedicated to the service of society. The results of his work played a significant role in today’s economic and cultural potential of our city. Mr Solovyov’s great experience in the organization of productive work in the port, the realization of his interests in studying historical characteristics of the land has not lost its practical value and is useful today.
