The dynamic urbanization process of China has stimulated a massive growth of urban settlements in the past few decades. With the development of remote sensing technology and the release of the long-time Landsat archive, spatial characteristics of urban settlement are gradually analyzed on a large scale, and various patterns are developed for describing and analyzing it. However, the urban settlement patterns were mainly quantified by the landscape metrics in existing studies, the underlying features shaping urban settlement pattern were always neglected. In this study, we establish a systematic and comprehensive ‘urban development index system’ for describing China’s urban settlement pattern and its evolutions during the end of the 1980s through to 2010 by using a series of statistical methods. Results show that (1) urban settlement pattern in 2010 is quantified comparatively simpler and more completely than in the end of the 1980s; (2) urban settlements in western and eastern regions present integrated pattern and homogeneous attributes, while urban settlements in central and northeastern regions present relatively complex pattern and various attributes; (3) urban settlements with the most variable pattern are accompanied by the most dynamic population and economic capacity, followed by landscape dispersion. Topographic complexity of urban settlements generally remained unchanged or with slight fluctuations, therefore, it has limited influence on settlement pattern evolution.

Informal Urban Settlements

ABSTRACTOld Fadama in Accra, Ghana, is a vast informal settlement. A legalistic approach by successive governments has meant a near-absence of statutory institutions and the emergence of alternative public authorities. These endeavour to provide the area with a range of basic public services to solve the area's serious developmental challenges. Through processes of informal negotiation residents establish rights and social contracts that underpin and define what will constitute ideas of state and law. At the same time, self-governance emerges while relations with statutory institutions shift back and forth between vilification, tacit acceptance, and productive cooperation. The article contributes to studies of governance in informal urban settlements on two fronts. First, it shows how informal arrangements lead to the provision of basic public services and influence the workings of formal institutions of government. Second, it challenges facile understandings of large-scale informal settlements as generally chaotic, lawless or subversive.

Cruel and inhumane acts that harm human life and health, as well as humiliate the dignity, are prohibited in most countries of the world, and Russia is no exception in this issue. The article presents an analysis of the institution of responsibility for torture in the Russian Federation. The author comes to the conclusion that the current criminal law of Russia superficially and fragmentally regulates liability for torture, in connection with which the author formulated the proposals to define such act as an independent crime. In the frame of modern globalization, the world community pays special attention to the protection of human rights, in connection with which large-scale international standards have been created a long time ago. The Universal Declaration of Human Rights and other international acts enshrine prohibitions of cruel and inhumane acts that harm human life and health, as well as degrade the dignity.Considering the historical experience of the past, these standards focus on the prohibition of any kind of torture, regardless of the purpose of their implementation.

The article assesses the intensity of transformation of settlement pattern in Yakutia, the largest northern region of Russia, based on an analysis of 1939-2010 censuses and contemporary statistics. Scope of the work includes the following: to assess key socio-economic results of rural and urban settlement pattern transformation in the 20th century, to determine the most persistent primary units of settlement pattern, and to identify current trends in the settlement pattern of Yakutia. The research database was built based on digitization of Federal State Statistics Service in the Sakha Republic (Yakutia) population censuses archives. The period under review shows a trend toward larger size of settlements due to two parallel processes: urbanization as a result of industrial development, and compression of rural settlement system due to amalgamation of rural settlements. From 1939 to the present time, Yakutia’s settlement system has been evolving from dispersed type to large settlement type. There were two major waves in the structuring of space in Yakutia. During the first one, caused by industrialization and complete collectivization, shrinking of rural settlement system was accompanied by setup of rural and urban settlements; it started in the 1930s and lasted until late 1950s. The second wave, concurrent with controlled compression of rural settlement pattern as part of elimination of unpromising sovkhoz state farms, was associated with a full-scale development of urban settlement pattern under planned Soviet deployment. Starting from 2002, market mechanisms have changed the direction of development of settlement system and spatial structure of economic activity. Despite several constraints, which include high transportation costs, focal development, key role of mining and resource sector, distinctive features of traditional economies and agriculture, agglomeration processes have gained momentum in the region. Spatial concentration of population is taking place at relatively high rates, primarily in the core of the system - Yakutsk agglomeration. Compression capacity of settlement system in the region is far from being exhausted, as evidenced by behavior of Theil and Herfindahl-Hirschman indices, as well as by average population density of settlements.

AbstractFor a long time, since China’s opening to the outside world in the late 1970s, admiration for foreign socioeconomic prosperity and quality of life characterized much of the Chinese society, which contributed to dissatisfaction with the country’s development and government and a large-scale exodus of students and emigrants to foreign countries. More recently, however, overestimating China’s standing and popularity in the world has become a more conspicuous feature of Chinese public opinion and the social backdrop of the country’s overreach in global affairs in the last few years. This essay discusses the effects of these misperceptions about the world, their potential sources, and the outcomes of correcting misperceptions. It concludes that while the world should get China right and not misinterpret China’s intentions and actions, China should also get the world right and have a more balanced understanding of its relationship with the world.

The Stability

The global economy continues to grow, albeit mainly due to large-scale support measures from governments and regulators. Moreover, the latter are not sure about the prospects for such development, since the economies do not demonstrate the potential for independent growth. As a result, in order to stimulate it, regulators are forced to expand the range of their tools, mechanisms, approaches, otherwise the risks to the stability of the global financial and economic system increase. All this is happening against the background of negative rates, which have become virtually ubiquitous and persist for a long time. New growth records are being set in the stock markets, and their gap from the real economy is growing. A number of sectors are beginning to dominate, forming distortions and bubbles in the markets. In such conditions, the importance of digital money, ecosystems, etc. increases. Moreover, the faster and more efficiently regulators can integrate into these formats, the more successful business, the population, and the economy as a whole will be.

- The article explores megastructures in relation to their impact on local transport networks and nodes. The area examined is Portugal, where the recent construction of giant shopping malls, industrial estates and logistics centres has in turn led to large-scale infrastructures that have been superimposed on a settlement pattern consisting, in many cases, of urban agglomerations serviced by rural roads. The resulting landscape reveals a juxtaposition of completely different elements in terms of both scale and impact, often the outcome of urban zoning projects intruding on fragmented urbanisation. The resulting image is one of scattered settlement patterns. Behind these phenomena one can see the effects of splintering urbanism. The difficulty in coordinating, in time and space, the decisions made and actions taken by a wide variety of individuals and institutions is becoming increasingly more complex.

The K-means algorithm is one of the ten classic algorithms in the area of data mining and has been studied by researchers in numerous fields for a long time. However, the value of the clustering number k in the K-means algorithm is not always easy to be determined, and the selection of the initial centers is vulnerable to outliers. This paper proposes an improved K-means clustering algorithm called the covering K-means algorithm (C-K-means). The C-K-means algorithm can not only acquire efficient and accurate clustering results but also self-adaptively provide a reasonable numbers of clusters based on the data features. It includes two phases: the initialization of the covering algorithm (CA) and the Lloyd iteration of the K-means. The first phase executes the CA. CA self-organizes and recognizes the number of clusters k based on the similarities in the data, and it requires neither the number of clusters to be prespecified nor the initial centers to be manually selected. Therefore, it has a “blind” feature, that is, k is not preselected. The second phase performs the Lloyd iteration based on the results of the first phase. The C-K-means algorithm combines the advantages of CA and K-means. Experiments are carried out on the Spark platform, and the results verify the good scalability of the C-K-means algorithm. This algorithm can effectively solve the problem of large-scale data clustering. Extensive experiments on real data sets show that the accuracy and efficiency of the C-K-means algorithm outperforms the existing algorithms under both sequential and parallel conditions.

A New Technique

There are now several large scale deployments of differential privacy used to collect statistical information about users. However, these deployments periodically recollect the data and recompute the statistics using algorithms designed for a single use. As a result, these systems do not provide meaningful privacy guarantees over long time scales. Moreover, existing techniques to mitigate this effect do not apply in the “local model” of differential privacy that these systems use. In this paper, we introduce a new technique for local differential privacy that makes it possible to maintain up-to-date statistics over time, with privacy guarantees that degrade only in the number of changes in the underlying distribution rather than the number of collection periods. We use our technique for tracking a changing statistic in the setting where users are partitioned into an unknown collection of groups, and at every time period each user draws a single bit from a common (but changing) group-specific distribution. We also provide an application to frequency and heavy-hitter estimation.

The paper assesses the determinants of intentional PE and VC monetary experts' ownership in the post-IPO period. I show that these monetary masters hold offers to direct potential managerial seizure of outside financial specialists, yet their support fondness depends basically on the focal characteristics of IPO, PE and VC firms, adventure, and divestment power of different pre-IPO speculators. I find that the financial benefactors' required holding is in a general sense greater in US than in UK IPOs. The assessment of the affiliate's trade execution, considering the timetable time approach, reveals strong negative ordinary month to month irregular returns for game plan of upheld IPOs over various holding periods, anyway the association between PE/VC purposeful ownership and the since a long time prior run execution is curved, prescribing that solitary colossal property make regard.
