Securing mobile devices: malware mitigation methods
As it is generally known, market of cutting edge technological devices (smartphones, tabs, etc.) is one of the most dynamic, competitive and knowledge intensive market in world. Thanks to that, market leaders always have to chase the latest tendencies and trends, in order to be in sync with consumers’ preferences. In this article authors present their study, conducted in 2016 year and focused on consumers’ preferences in Moscow smartphone market. In order to obtain information about such preferences, authors used Google Forms platform. This platform, being able to conduct audience survey, provided authors with reliable information, answering the three types of questions: social-demographic; questions focused on respondents’ consumer attitude to smartphones and their intended use and cluster allowing to simulate the optimal combination of smartphone characteristics when choosing its model by a consumer.
Generally, this audience survey, designed by authors as a questionnaire, divides all the questions, described above, into two following blocks: first block contains general social-demographic questions such as respondent’s sex, age, marital status, professional specialty and work experience, while the second block includes respondents’ individual preferences in smartphones’ choice. Using both parts of the survey, authors made a full processing of the data obtained and then conducted conjoint analysis of consumers’ choice. The conducted study allowed to identify the most influential factors on the Muscovites’ choice of smartphones’ functions and their target use. For instance, for 73% of respondents questioned camera was the most valuable function of a smartphone, while 64% of them permanently use their smartphones for Internet communications. The authors also found the statistically proven dependence between the frequency and length of smartphone’s use and social-demographic factors. In addition to the abovementioned analysis, authors presented and described the structure of respondents’ preferences.
In the course of this study the authors managed to gather a large amount of source data that allows comprehensive analysis of the target field. In conclusion, it is necessary to add that the obtained results may be useful for market players of cutting edge technological devices and for anyone, interested in information technologies development in modern society.
Modern corporate culture in the context of Bauman’s liquid modernity is greatly defined by the level of freedom, in particular, flexibility, mobility, new technologies and mass communications. Staying connected 24/7 both in professional and private life known as ‘hyperconnectivity’ becomes commonplace. Hyperconnectivity entails not only positive but also negative consequences regarding the effectiveness of an individual’s work as well as the work of entire organizations. The purpose of the article is to consider the negative aspects of the use of mobile devices as a way to establish work-life balance in the context of modern liquidity. Individual’s ‘right to disconnect’ minimizing the adverse effects of hyperconnectivity is essential to the analysis of the issue. The right to disconnect is a new addition to the list of labor rights allowing an individual to disconnect from the work primarily by switching off email or disabling workrelated messages during nonworking hours. To study the need to introduce ‘the right to disconnect’ and to achieve a better work-life balance the authors examine the labor practices in South Korea and two European countries (Germany and France).
The work carried out research and development of methods for the dynamic configuration of the smart thing's interfaces on the mobile devices with limited resources. This article describes a mathematical model of the environment for dynamic reconfigurable interfaces of smart things on mobile devices with limited resources, the method of assigning a set of basic interface elements to reconfigure interface of smart things and heuristic algorithm for dynamic smart thing's interface reconfiguration.
Mobile Ecosystems have been related to products, or to a community of developers around a product and gives the certain advantages to the platform owners and participants of the ecosystem. The paper answers the question -- what are the existing approaches to build mobile ecosystems, who are the participants and what are their benefits?
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.
