Бродвей в разрезе:профильное районирование как методика полевого исследования
Broadway is the most famous street of New York City. It follows the island of Manhattan along its whole length and through many of its vernacular regions. Field research of functional, social-economic, architectural and mental differentiation of the street from Bowling Green to 142 Street in Spanish Harlem shaped the methods of linear zoning and revealed 16 unique regions in the researched segment. These regions turned out to be functional, but their borders and composition are based on the vernacular regions of Manhattan. It appears that Broadway, as a major trade and social thruway, forms the surrounding urban landscape. But the role of vernacular regions, through which street passes, remains important and sometimes even crucial.
Scientists and politicians are absolutely sure that we require a professional approach to solving such problems as generation and diffusion of innovations; that is why many universities nowadays offer new degree programs in this field. The author explains why companies need innovation managers. Also, he propones a method for conducting express assessment of company’s innovation activity which will allow to assess its organization and to define functions and tasks of innovation staff. Some recommendations on innovation staff training are given.
This article discusses spatial changes in the ethnic territories of Native Siberians from the late nineteenth century to the early twenty-first century. A Geographic Information System (GIS) was developed to model and observe these changes. The GIS also features resource-oriented economic activities, major waterways and railroads. Analysis of the model, textual sources and statistical data made it possible to determine what factors constituted Siberia’s ethnographical pattern of the early twentieth century and led to its changes in the ensuing decades and what impact on the indigenous peoples these changes had. Four special maps showing Siberia in the 1900s–10s, 1930s–40s, 1970s–80s and 2000s–10s were produced from the GIS and are included in the article. The current legal status of the indigenous peoples’ territories was also examined. This article presents an interdisciplinary macroscale case study.
The Baikal region in Siberia had long been a zone of interactions between various European, Asian and global actors. Numerous relational spaces which were produced by the interactions were reconstructed in a geographic information system (GIS) and analysed jointly. The fall of the Qing and Russian empires resulted in energetic attempts to redraw administrative and international boundaries. Between 1917 and 1919 several disentanglement projects were developed and implemented by different actors, including indigenous intellectuals and Buddhist monks. These were the Buryat Autonomy proclaimed in 1917; the Buddhist theocracy created by a dissident Buddhist monk Lubsan Samdan Tsydenov; and the pan-Mongolian federation of Inner, Outer, Hulunbuir and Buryat Mongolia supported by Japanese officers and a regional Cossack leader Grigory Semenov. Each project underlined a certain group identity and claimed particular relational spaces. The article explored how the conflicts between overlapping identities were resolved, and why all three projects failed.
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
The Handbook of CO₂ in Power Systems' objective is to include the state-of-the-art developments that occurred in power systems taking CO₂ emission into account. The book includes power systems operation modeling with CO₂ emissions considerations, CO₂ market mechanism modeling, CO₂ regulation policy modeling, carbon price forecasting, and carbon capture modeling. For each of the subjects, at least one article authored by a world specialist on the specific domain is included.
