Examination of the real estate market shows that implementing innovations in this field is a very difficult task. This prompts the question of the necessity of digitalizing the real estate business and of the demand for online integration platforms in this field.Aim. The presented study aims to assess the demand for online integration platforms in the real estate business.Tasks. The authors compare the online integration platforms in the real estate market with the online integration platforms in the hospitality sector and the individual passenger transport market in terms of the share of user profits that integrators receive for their services on the online platform; compare the share of user profits that integrators receive for their services on the online platform with the equivalent indicator in various other global economic activities; assess the value of the services provided by an online integration platform using the methodology proposed by G. G. Azgaldov and N. N. Karpova.Methods. The data were acquired from public Internet sources and personal interviews with the directors of companies that represent or employ the services of online integration platforms in St. Petersburg. The interviews and work with Internet sources were conducted in November 2019.Results. An integrator in the real estate market receives a share of profits of their service users that is comparable to that of the integrators in the hospitality sector and the individual passenger transport market. The share of profits of a Russian integrator in the real estate market is significantly higher than that in such industries as entertainment, fashion, or sports. The value of an online integration platform can be defined as highly valuable, since the expected value of this indicator is 1.5 times higher than the maximum table value.Conclusions. The performed analysis shows a high demand for online integration platforms in the real estate business. Market participants are willing to pay for the ability to use new digital technologies.

Using spatial econometric techniques and local spatial statistics, this study explores the relationships between the real estate values in Tuscany with the individual perception of satisfaction by landscape types. The analysis includes the usual territorial variables such as proximity to urban centres and roads. The landscape values are measured through a sample of respondents who expressed their aesthetic-visual perceptions of different types of land use. Results from a multivariate local Geary highlight that house prices are not spatial independent and that between the variables included in the analysis there is mainly a positive correlation. Specifically, the findings demonstrate a significant spatial dependence in real estate prices. The aesthetic values influence the real estate price throughout more a spatial indirect effect rather than the direct effect. Practically, house prices in specific areas are more influenced by aspects such as proximity to essential services. The results seem to show to live close to highly aesthetic environments not in these environments. The results relating to the distance from the main roads, however, seem counterintuitive. This result probably depends on the evidence that these areas suffer from greater traffic jam or pollution or they are preferred for alternative uses such as for locating industrial plants or big shopping centres rather than residential use. Therefore, these effects decrease house prices.

Data Processing Method

With the wide application of intelligent sensors and internet of things (IoT) in the smart job shop, a large number of real-time production data is collected. Accurate analysis of the collected data can help producers to make effective decisions. Compared with the traditional data processing methods, artificial intelligence, as the main big data analysis method, is more and more applied to the manufacturing industry. However, the ability of different AI models to process real-time data of smart job shop production is also different. Based on this, a real-time big data processing method for the job shop production process based on Long Short-Term Memory (LSTM) and Gate Recurrent Unit (GRU) is proposed. This method uses the historical production data extracted by the IoT job shop as the original data set, and after data preprocessing, uses the LSTM and GRU model to train and predict the real-time data of the job shop. Through the description and implementation of the model, it is compared with KNN, DT and traditional neural network model. The results show that in the real-time big data processing of production process, the performance of the LSTM and GRU models is superior to the traditional neural network, K nearest neighbor (KNN), decision tree (DT). When the performance is similar to LSTM, the training time of GRU is much lower than LSTM model.

Angesichts des markanten Aufstiegs des Rechtspopulismus in den vergangenen Jahren drängt sich die Frage immer wieder auf, ob oder inwiefern das Parlament den eigentlichen Volkswillen (noch) vertreten kann, und wie im Zeitalter der Globalisierung und Digitalisierung der eigentliche Volkswille überhaupt festzustellen und effektiv durchzusetzen ist. In dieser Hinsicht steht das Vertrauen in die Fähigkeit des Parlaments, den wahren Volkswillen herauszubilden und zu artikulieren, erneut vor großen Herausforderungen. Durch eine vergleichende Analyse zwischen den Demokratietheorien Böckenfördes und Kelsens zeigt der vorliegende Beitrag, weshalb und inwiefern das weitverbreitete Verständnis des Volkswillens und dessen Rolle in der parlamentarischen Demokratie gerade vor dem heutigen Hintergrund eine kritische Besinnung verdient. Es wird argumentiert, dass gerade in demokratischer Hinsicht nicht die Suche nach dem „wahren Volkswillen“, sondern nach wie vor die Gewährleistung der Menschen- bzw. Grundrechte der Einzelnen und insbesondere der Minderheiten von zentraler Bedeutung sein soll. In view of the spread of right-wing populism in recent years, the question as to how the will of the people is to be ascertained and expressed has attracted much attention in constitutional scholarship. In particular, the issue of whether or to what extent the parliament is (still) capable of representing and demonstrating the will of the people has been repeatedly discussed and debated. Through a comparative analysis of Böckenförde’s und Kelsen’s democratic theories, this article critically examines the problems of the widespread understanding of the will of the people as a real-empirical existence and its significance for the realization of democracy. Accordingly, it points out why and in what sense the reference to the so-called real will of the people would undermine rather than promote democracy. This article concludes by arguing that, precisely for the sake of democracy, what is crucial is not to determine what the “real will of the people” is, but rather to guarantee the freedom of the individual and especially of the minorities.
