The authors propose the informative and formal description of Structure Dynamics Control Task of Cyber-physical Systems (CPS). The main advantage of proposed poly-model multicriterion approach for the structure dynamics control tasks decision is that, in comparison with previously developed control models oriented on CPS simulation, proposed models allow to increase the efﬁ ciency, validity and, in general, the quality of the SD control CPS due to the original combination of their static and dynamic models
This paper uses representative student data from St. Petersburg, Russia to
analyze school segregation by parental socioeconomic status and student
academic performance. The proposed systematic segregation indices
account for ordinal variables and take expected segregation into
account. We decompose segregation by school type, school, and classes
and compare the results to results obtained from PISA for urban areas in
Russia and six European countries. Segregation by socioeconomic status
is moderate in St. Petersburg and Russia, as compared to other
European countries. Segregation between schools and school types
reflects parental choice, whereas within-school segregation along the
lines of student performance reflects school policies.
Tourism products’ variety engenders a correspondingly large number of approaches to their promotion. One popular angle for promotion, applicable in a handful of cities, draws on the destination's imperial heritage. However, the patterns of using the imperial theme for tourism marketing vary in different capitals. This study is the first in a larger project aiming to study the former imperial capitals (St. Petersburg, Istanbul, Berlin, and Vienna). Our overall goal is to understand, first, how city representatives and travel agencies narrate the “imperial” past and turn it into a competitive advantage for the city, and second, how tourists react to such narratives. To collect and analyze the data, we used web scraping and text mining techniques. In this article, we present the first results of our study using the case of St. Petersburg.
Despite the fact that user-generated data are widely used in medical informatics in general and for revealing side-effects of various pharmaceuticals in particular, recent studies have focused merely on methods of extracting information on side effects from unstructured or semi-structured reviews of specific medications without linking side effects to any outcomes.
In this study we demonstrate how user-generated online content on side effects experienced by patients while taking a pharmaceutical product can be used to do research after the drug has been introduced to the market, thus allowing to complement the results of official clinical studies and market research. In particular, we concentrate on revealing the contribution of various side effects to reported customer satisfaction with Tamiflu, a popular antiviral drug.
Publicly available data from an online platform with reviews from patients are used as an input to the analysis that applies statistical and machine learning methods (multivariate logit models and classification trees) to investigate the relationships of side effects to demographic characteristics and to the overall satisfaction with the medication.
We prioritized side effects of Tamiflu based on the significance of their association with patient’s ratings published at one of the well-known drug discussion forums. Among all types of side effects used in our study, the neuropsychiatric symptoms and body pain are the most influential, followed by skin problems. Specific combinations of side-effects that are associated with low satisfaction were detected.
The proposed analytical approach can help pharmaceutical companies to improve their products and/or medical guidelines associated with their products and figure out fighting which adverse effects should be given a priority from the customer satisfaction perspective.
Stock-out – an inventory shortage, is a situation which periodically or constantly
retailers, networks of retail trade (and other commercial organizations connected
with replenishment and stocks expenditure) face worldwide. Numerous publications
of foreign authors proposing practical solutions for such organizations is
a vivid example of it. Some retail chain stores and enterprises even issue guidebooks
to handle stock-out.
In domestic literature, there are publications describing various stock-out
forms, as well as recommendations associated with the decision-making on them.
Nevertheless, the experience connected with the prevention and struggle
against the stock-out consequences is uncoordinated, lacks common structure, and
sequence of actions. An enterprise facing stock-out receives only fragmentary data
on the nature of this phenomenon, necessary instruments of influence and the sequence
To give an idea of the existing spectrum of analytical approaches and possible
practical solutions, is one of the main objectives of this article. At the same time,
issues related directly to determining the stock volume and other parameters of a
company's inventory management system are considered. Based on the analysis
of the issues described above, a possible algorithm of actions an organization can
follow in the event of a stock-out, is presented. The possible development of an approach
to manage the most complex stock-out case – «with a lost demand» is also
The book presents classic works on the nature of interest rate and its regulation: John Locke's pamphlet "Some considerations about the consequences of lowering interest rates and increasing the value of money" (1691) and a series of letters to Jeremy Bentham "In defense of usury" (1789). Both works, first translated in Russian, have had a significant impact on the evolution of the understanding of interest rate and the problems of its regulation. In addition, the collection includes articles by Russian authors on the development of usury, the scientific heritage of John Locke and J. Bentham, as well as a modern look at the ethical component of interest regulation.
The objectives of the study were (a) to identify the reasons and concerns of those public administrators and marketing scholars who do not accept the usefulness of marketing in the public sector; (b) to deconstruct, comprehend, interpret, and critically appraise the current conceptualization of public sector marketing from the viewpoint of negativists identified in step (a); and (c) to reconstruct, redefine, reinterpret, and reoperationalize the current controversial conceptualization of public sector marketing into a new conceptualization in the context of park and recreation services. The critical theory approach to the study primary used non-empirical procedures data collection and analytic procedures which included investigative research, negative case analysis, and theoretical triangulation. These procedures were supplemented with empirical data collected from in-depth interviews with five scholars and with three parks and recreation managers. Results of the non-empirical procedures revealed the biased selective nature of the current conceptualization of public park and recreation marketing and the existence of alternative conceptualizations which have been ignored. The existing and alternative models were discussed with scholars and park and recreation managers. Support was found for the alternative models. From these data an alternative conceptualization of public park and recreation marketing was developed and named the concept of administered marketing. Implications for park and recreation managers are discussed. Directions for future research into the administratively managed park and recreation marketing concept are suggested.
This article explores the relationship between educational outcomes and anti-school attitudes at different levels of social organization in schools. Data were collected in St. Petersburg, Russia (104 schools, 7300 students) and analyzed using multi-level regression models that included three levels: individual, clique of friends and school. A clique is defined as a tight group of friends in a school class; we used social network analysis software Kliquefinder for clique identification. We demonstrate that friends’ attitudes are strongly related to the educational outcomes of a student (net of person’s individual attitudes and socio-demographic characteristics). In contrast, school-level effects disappear in the multi-level model when individual characteristics are included. The results of the study clearly demonstrate that the socio-economic and curricular differentiation of schools does not always lead to the polarization of ‘school academic cultures’. A school social environment is sufficiently heterogeneous, and different value systems in small peer groups may coexist.
Client satisfaction is a critical element that equally affects firms’ competitiveness in manufacturing and service industries. The competitiveness is highly dependent on the mediating role that client satisfaction plays on consumers’ loyalty, and this is especially relevant in the turbulent periods lived after the financial crisis of 2008. A simple glimpse at the growing number of publications on client satisfaction shows the relevance of the topic. The aim of this paper is to analyze the evolution of articles published by Russian and non-Russian authors to see whether the experience of the former Soviet Union autocracy and the transition from this regime to market economy has played a significant role explaining the differences in approaches and topics under analysis as well as the rate of convergence between these two once separating worlds. The analysis is based on a systematic literature review of a first set of 1685 articles on client satisfaction in the Scopus and eLIBRARY databases. A further step based on only 200 relevant articles is made to find that the breach between these two worlds has been reduced, but there are still some differences regarding the social and economic components of the relevant literature. Some avenues for the future research that can advance a better understanding on the client satisfaction and the effects on the firms’ competitiveness after the existing new political agenda are briefly introduced.
This book suggests that normative ethics should be developed as a social science, and that this will improve its reputation in business and society. Storchevoy defines four criteria of a good scientific method (clear definitions, correct logic, empirical verification, accurate measurement) and demonstrates how normative ethics can make use of them. He provides a historical review of the methodological evolution of normative ethics and outlines how it was moving in a nonlinear way towards this scientific development by the 16th century. A Scientific Approach to Ethics challenges the reputation of ethics among many within business and business schools as unscientific and argues that it can come to be seen as a scientific discipline able to reveal universal moral truth.
The purpose of this article is an attempt to apply media review method to consumer behavior problematic situations using examples from the comedy movie "Heartbreakers". The short plot, two marketing cases, and their analysis with lessons are presented. Results suggest that service recovery strategies developed by marketers are not enough to deal with problematic customers.
Purpose – The purpose of this paper is to analyse the demand for tickets in the Brazilian State
Championships focussing in the impact generated by the brand teams as well as the play-off matches in the
demand for tickets and, consequently, in the match day revenues.
Design/methodology/approach – An equations system by three-stage least square estimator is
employed. The data set comprises 1,114 matches from Mineiro, Carioca and Paulista Championships over the
Findings – All explanatory variables increase both attendance and match day revenues. However, the most
important goal is the distribution of wealth found. The presence of brand teams in those championships
provides a financial aid for smaller teams.
Practical implications – The proposals from the mass media to exclude the brand teams and design those
championships exclusively in play-off stages should not be implemented by the policymakers. On the
contrary, rearranging the design of the competition with more matches between small teams and brand teams
may help to all of them.
Originality/value – The paper contributes to introduce the Brazilian State Championships in the sport
economics literature as well as evidences the redistribution effect of wealth among clubs.
The book considers how to make the methodology of business ethics more scientific, especially its normative branch. Storchevoy explores the attempts of economic theory to contribute to the scientific normative analysis of economic behavior, particularly the welfare economics of 1910-1950 and methodological discussions of economics and ethics from 1980-2015. He then examines the development of the methodological structure of business ethics in general since the 1980s and the scientific validity of normative business ethics, including stakeholder theory, the separation thesis, integral social contract theory, corporate social responsibility, virtue ethics and other frameworks. He concludes by suggesting an additional step to make business ethics a more systematic discipline by developing a typology of moral issues and dilemmas. Business Ethics as a Science will be a thought-provoking resource for students and practitioners of business ethics and economists alike.
Crowdfunding platforms develop as a valuable business model in sharing economy. Through intensive market development, a question arises: what it takes for a crowdfunding project to succeed. This paper aims to identify the features of crowdfunding projects influencing the outcome. The country‐of‐origin effect is taken into account to compare the outcomes in Russian crowdfunding platform and the worldwide known Kickstarter platform. Machine learning methods are applied to primary data regarding projects on these two platforms to determine and to compare the influence of factors. The results show that there is a difference in strength of factors’ influence on the Russian platform as compared to Kickstarter.
Telecommunication enterprises in Russia have to constantly update their own material and technical base in order to maintain their competitive positions in the market. Uninterrupted performance at the brink of the capacity of modern technologies causes a steady demand for equipment and hardware components that include a great share of innovative parts, and the vast majority of them are not produced in the domestic market. Advanced currency risk management as an integral part of the enterprise risk management system can deliver the best options for purchases policy and free capital allocation in the money market, thus it can significantly improve the overall corporate efficiency in high-tech enterprises.
Although research and writing for publication are seen as important responsibilities for most graduate students and faculty, many struggle to understand the process and to succeed. Unfortunately, writing centers at most universities do not cater to these kinds of needs, but rather to course-specific needs of undergraduate students. This chapter describes a writing center, The Office of Academic Writing and Publication Support, at Florida International University, USA that was specifically designed to aid the scholarly writing endeavors of graduate students. First, the authors review literature on how individual instructors and programs assist graduate students in improving their writing skills. Then they provide a history of university writing centers and examine the evolution of their purpose. In the second half of the chapter, the authors share their experiences envisioning and building this writing center and creating, implementing, and improving its services. In doing so, they also reflect on successes and missteps along the way. The authors hope this chapter may be especially helpful to educators who seek to create similar centers or services at their own institutions
The carried out studies show that from the point of view of the issue of efficiency increase of logistical systems, there are several key aspects. Firstly, choice of methods for managing the triad of logistics functions ‘inventory management - warehousing – transportation’, where the inventory management issues are considered as the most relevant ones. Secondly, there is recognized the need to move the studies of multi-level systems within the framework of the concept of supply chain management.
Nowadays, supply chains, which are represented by the distribution system, are widespread in practice. The most common of them are two-level ones with a central supplier at the second level and a certain number of companies at the first level; and multi-level systems of the distribution configuration network in which multi-nomenclature stocks are located. The article is devoted to the design and enhancement of analytical platform for inventory management in such distribution systems.
