Некоторые аспекты использования информации, доступной в Интернете, для моделирования спроса
Internet Studies is an interdisciplinary and multidisciplinary field of fundamental and applied research that integrate different research disciplines with a common object, that is the Internet. This review article gives a definition and a brief description of the structure of Internet Studies as part of the social sciences and introduces research agenda of this field, including most cutting edge research issues. The agenda of Internet Studies related to classical sociological issues are analyzed in more detail: inequality, online communities and social capital as well as topics related to the study of transformations in different spheres of society - politics, public health and medicine, education. Two main theoretical approaches are briefly described, within which the influence of the Internet on society is interpreted: the network society theory and critical theory of the Internet and society. We conclude that the present directions of Internet research have many intersections with each other, and the perspective of a more complete study of the mechanisms, that mediate social changes related to the Internet and connect online and offline sociality into a single space, opens at these intersections.
Study is aimed to estimate the relation between producer effect from employing a downsizing strategy and the number of such producers. For this purpose we train sales prediction model on the actual sales data from a large retail grocery chain and estimate the average effect from implementing downsizing strategy under different market conditions
In the year of 2018, the Internet is no more a wholesome phenomenon, but when recognised as a subject of studies, becomes similar to a teenager having already gained a certain independence. It understands its communication with other people but still wants to change the whole interaction system in order to nd its own place. At least, this is exactly the impression we receive: the impres sion of an ambitious object of study, of a misunderstood one. In this issue we offer you an occasion to think about different scenarios of the relationship between studies on the Internet and classic social sciences approaches. We do not focus on methodological issues, but on the Internet in its being an object of studies and a scienti c problem. We focus on studies on the Internet that accumulate knowlege about the Internet as a social phenomenon, being also an internation al and indisciplinar area of research. So cial sciences are represented in this case by sociology and anthropology, as well as other ones such as mediastudies, stud ies on sciences and technologies (STS), social geography etc.
This article contains a prediction model for the demand for the consumer commodities. I consider the classical model of the consumer utility function maximization in a given budget constraint where there are two products: the first one for which the demand is being estimated, and the rest of the consumption bundle which is the second product. The utility function is introduced as multiattributive utility function with an unidentified number of attributes. An approach to estimate the exact number of attributes and the parameters of the model in a given class of utility functions for each attribute was proposed. The estimation is derived through the optimization of corrected Akaike information criterion, where the parameters of the utility function are continuous and the number of attributes is integer and positive. This model was tested on the prediction of the homogenous product demand with the Giffen effect.
