Асимметричность информационных потоков: причины, возможности управленческого воздействия

Subject. This work is devoted to the study of the asymmetry of information flows. To identify the causes of asymmetry and the possibility of managerial influence on the asymmetry of information flows. Goal. The study of the concept of "asymmetry of information flows", identification of the causes and possibilities of managerial influence on this process. A method or methodology. The research methodology is based on the application of methods of analysis and synthesis, induction and deduction, comparison, a systematic and logical approach, the method of analogies and grouping. The results of the work. Information asymmetry is a situation in which some market participants have information, but it is not available to other interested parties. There are two types of information asymmetry: hidden characteristics and hidden actions. The reasons for the asymmetry of information flows are related to resource costs, obsolescence of information, lack of opportunity or knowledge and skills to evaluate the available information in full. One of the consequences of information asymmetry is a sharp drop in the level of public welfare. Incompleteness of information is an integral part of economic life, which in turn affects the conditions and features of the markets and causes additional transaction costs. Conclusions. Information asymmetry is an intrinsic feature of the market, its impact on the functioning of the market is always multifaceted and depends only on the degree of asymmetry. It affects both consumer behavior and firm strategy, as well as competition.

Analysis of mobile edge computer networks based on a specialized framework

A framework is presented as a set of programs designed to analyze various computer networks of edge computing. It includes special classes for describing mobile units, servers, as well as workloads – streams of tasks to be solved. The framework allows you to simulate the characteristics of the terrain on which the network nodes are located. The work with the framework is demonstrated when analyzing such parameters as the amount of information obsolescence due to delays in solving problems and the time of active functioning of peripheral nodes in random walk models. The results of the analysis are presented as dependency plots.

Data obsolescence detection in the light of newly acquired valid observations

The information describing the conditions of a system or a person is constantly evolving and may become obsolete and contradict other information. A database, therefore, must be consistently updated upon the acquisition of new valid observations that contradict obsolete ones contained in the database. In this paper, we propose a novel approach for dealing with the information obsolescence problem. Our approach aims to detect, in real-time, contradictions between observations and then identify the obsolete ones, given a representation model. Since we work within an uncertain environment characterized by the lack of information, we choose to use a Bayesian network as our representation model and propose a new approximate concept, $\epsilon$-Contradiction. The new concept is parameterised by a confidence level of having a contradiction in a set of observations. We propose a polynomial-time algorithm for detecting obsolete information. We show that the resulting obsolete information is better represented by an AND-OR tree than a simple set of observations. Finally, we demonstrate the effectiveness of our approach on a real elderly fall-prevention database and showcase how this tree can be used to give reliable recommendations to doctors. Our experiments give systematically and substantially very good results.

W11. GENOME-WIDE ANALYSIS OF THE ANXIETY DISORDER SPECTRUM

The information describing a person is constantly evolving and may become obsolete and contradict other information. A personal database, therefore, must be consistently updated upon the acquisition of new valid observations that contradict obsolete ones contained in the database. This study focuses on proposing a novel approach for dealing with the information obsolescence problem in the elderly-fall prevention context. Our approach aims to continuously monitor elderly information in order to detect the change in the behavior of an elderly person and to prevent him from falls. It consists of detecting contradictions between newly acquired information about a single elderly and what we already know about that person, then identifying among his observations those that have become obsolete and need to be updated. We propose a new approximate concept,£-Contradiction, which represents the confidence level of having a contradiction in a set of observations when a causal Bayesian network is our representation model. We propose a polynomial-time algorithm for detecting obsolete information and show that the resulting obsolete observations are given as an explanation AND-OR tree.

Contemporary status of topographic mapping in Ukraine

Abstract The fundamentals and contemporary status of topographic mapping of Ukraine’s territory has been studied. Prior to declaration of Ukraine’s independence, its territory was covered with 1:10,000 to 1:1,000,000 scale topographic maps made by sub-divisions of the Chief Department of Geodesy and Cartography affiliated with the Council of Ministers of the USSR (GUGK USSR) and sub-divisions of the Military Topographic Service (MTS) of the USSR Armed Forces. Topographic mapping related cooperation between these institutions has been described. Topographic study of Ukraine’s territory as at 1991 has been subject to close analysis, with due consideration of the coordinate systems used for topographic maps. During the first years after Ukraine’s independence declaration topographic maps in Ukraine were made according to the previously effective Soviet instructions in the 1942 coordinate systems and 1977 Baltic height system. Since mid 1990s, Ukraine enjoyed transition from analog technology of making topographic maps to digital one. The contemporary legal and statutory support of topographic mapping in Ukraine has been studied; the implementation since 1 January 2007 of the UCS-2000 national geodetic reference coordinate system and the height system measurement works have been analyzed. Focus has been made on obsolescence of information of contemporary topographic maps and on extensive deprivation of secrecy for topographic maps in 2000s. Critical for the development of topographic mapping in Ukraine is now the Law of Ukraine “On National Geospatial Data Infrastructure” adopted in 2020. The Topographic Service of the Armed Forces (TS AF) of Ukraine carried out big scopes of works to update the topographic maps related to Russia’s military operations against Ukraine.

Improving access to health of Migrants in France. Qualitative assessment of a national guide

Abstract The National Public Health Agency and the Committee for the healthcare of persons in exile are providing, in the service of professionals, a Practical Guide for the care and the accompaniment of Migrants Foreigners living in precarious conditions, in France. The 2015 edition of this guide has been subjected to qualitative assessment in order to gather information regarding its use, the way it is perceived by its users, as well as their subsequent expectations, in order to design a new version that is more adapted to their needs. The study was carried out in December 2018 by an independent market research institute with the following design: 24 face-to-face interviews, whose duration was 1h30min, involving current users or past users: 6 working in structures specialised in accommodation for migrants, 6 in health care facilities, 6 in municipal or departmental social service facilities.3 focus groups, of 7-8 people, whose duration was 2H30min, involving potential future users of the guide. The recruitment of the participants took place in 3 cities as well as the overseas departments. The findings show: the legitimacy of this guide which is co-produced by an official national agency and an association recognized for its expertise.the interest of a transversal and multi-professional approach which allows to better grasp the social, legal and medical support and carethe need for information and operational resources This assessment underlines the relevance of the content and the symbolic importance of this guide which ’materializes’ the needs in terms of access to the rights and health of migrant people, often overlooked by professionals and administrations. It is thus a vehicle of vocational training and advocacy on this subject. The study provides concrete ways of optimization, particularly via digitalization, in order to cope with the rapid obsolescence of information, the availability of local directories and the need for exchange of professional practices. Key messages A national guide co written by a national agency and an association is a relevant tool to draw attention to migrants needs. Qualitative assessment highlighted the operationnal and symbolic role of this guide to foster cross professionnal work.

THE IMPLEMENTATION OF TECHNICAL INTEROPERABILITY MODELS IN LARAS VERSION 1.0 DIGITAL LIBRARY APPLICATIONS:A CASE STUDY IN THE CENTER FOR SCIENTIFIC DOCUMENTATION AND INFORMATION – INDONESIAN INSTITUTE OF SCIENCES

This study aims to find out models implementation of the technical interoperability applied and developed on the Digital Library Applications of the Library and Archive Analysis System version 1.0 (LARAS v 1.0) by the Center for Scientific Documentation and Information-Indonesian Institute of Sciences (PDII-LIPI). The other goal of this study is to determine why PDII-LIPI tries to develop LARAS v 1.0 and has changed the previous application of WINISIS. This study was done by using a case study method with qualitative approach. Data was collected by documents analyses and in-depth interviews. This result of the study shows that LARAS v 1.0 was created by developers at PDII-LIPI to avoid the obsolescence of information and technology communication (ITC), in this case, is the digital library application. In fact, the conflicts between the developers and the librarians in developing LARAS v 1.0 still exist. Models implementation of technical interoperability applied to LARAS is a combination of several levels of Level of Information System Interoperability (LISI) model. Nevertheless, in practice, LARAS v 1.0 is still not perfect, especially from the point of view of system development of metadata, encoding, communication protocol, databases, and indexing.

Estimating the crisis information coverage model in the internet communities

PurposeIn this study, the process of crisis information communication is viewed as a systems-based concept. An integrated and systematic three-phase model has been constructed to describe the process of crisis information coverage on the internet. By analyzing factors in the three stages that affect the coverage ratio and speed, this study aims to explore the law of information communication in this process and provide useful evidence for crisis managers to make informed decisions.Design/methodology/approachA complete information communication model has been constructed including the following three stages: crisis information release, crisis information diffusion and crisis information reception. The effects of important factors and variables in the model have been studied, including the crisis information release quantity, crisis information release mode, crisis information diffusion speed and crisis information obsolescence speed.FindingsThe quantitative analysis shows that crisis information release quantity and diffusion speed are positively correlated with coverage ratio; crisis information obsolescence speed is negatively correlated with coverage ratio; and crisis information release mode affects the speed of coverage but does not affect the final coverage ratio.Originality/valueTheoretical value: from the perspective of systems thinking, a detailed, systematic and coupled information coverage model has been constructed. Application value: this study finds the most efficient methods to regulate coverage speed and final rate, knowledge of which may play an important role in guiding the practice of crisis communication management.

A remarkable example in three-dimensional informetrics. The geometric law: Distribution of use or distribution of structure?

This article offers a mathematical model that is in line with three-dimensional informet- rics. We show that the geometric distribution – often found in informetric processes of use to model the distributions of book loans in libraries, of citations, or of journals downloads in scientific databases – plays a surprising role. To show this, we infer the existence of another distribution, which we have called “distribution of structure”. Distributions of use and distributions of structure are the two key processes in our three-dimensional IPP (Infor- mation Production Process). Furthermore, we indirectly introduce the time dependence of these distributions through the concept of information obsolescence. To demonstrate the theorems, we use the properties of probability-generating functions (PGF).

Pedagogical Maintenance of Future Teachers’ Practice-oriented Training

In modern world momentous events took place in the field of education due to the general processes of globalization and democratization. The European Higher Education Open Space was created. Through understanding of shared values and belonging to a common social and cultural space “A Europe of Knowledge” became not only an irreplaceable factor for social and human development, but a necessary component to consolidate and enrich the European citizenship. At the same time, education in Russia is also going through a difficult period of reassessment of social, moral and cultural values, and defines a new vector of the theoretical and practical orientation of the future teacher’s training. The refusal of knowledge-paradigm is taking place; this paradigm was lying for many years at the heart of the Russian fundamental education and was unable to solve the problem of the separating knowledge from skills to apply them. The current social situation has caused an acute shortage of qualified practice-oriented staff experienced by the real economy in spite of the large number of specialists with higher education. One of the causes resulting in the crisis of the traditional paradigm is the rapid information obsolescence which led to a change in a key orientation of education: from “teacher’s translating the required stock of knowledge to the students” to “education throughout life” (lifelong learning). In addition, the labor market was in need for not the knowledge as such, but the specialist’s ability to acquire and put it into practice by performing certain professional and social functions. That is why in today’s society there is a need for teachers of the new sociocultural type, capable of ensuring the training of professionals of another level (practitioners rather than theorists). The innovative style of the scientific and pedagogical thinking, the willingness to take creative solutions and create new values, the individual style of pedagogical activity, capacity for reflection, the need for continuous self-education and commitment thereto must be integral features of the modern teacher. According to the provisions of the Federal National Educational Standards of basic general education, the transition from subject-based learning to learning implementing a system-activity approach involving the training of students for professional and social life is required. In this regard, one of the important issues of the would-be teacher training in Russia is the lack of their practical preparation for professional activities. The article describes the experience of Elabuga Institute of Kazan (Volga) Federal University on the implementation of the model for updating the content of pedagogical cycle disciplines, and enhancing their practical orientation. The author, one of the developers of the content module “Disciplines of professional cycle of basic educational program: design and implementation of educational processes”, presented the experience of its approbation.

Map-Aided Evidential Grids for Driving Scene Understanding

Evidential grids have recently been shown to have interesting properties for mobile object perception. Possessing only partial information is a frequent situation when driving in complex urban areas, and by making use of the Dempster-Shafer framework, evidential grids are able to handle partial information efficiently. This article deals with a lidar perception scheme that is enhanced by geo-referenced maps used as an additional source of information in a multi-grid fusion framework. The paper looks at the key stages of such a data fusion process and presents an adaptation of the conjunctive combination rule for refining the analysis of conflicting information. This method relies on temporal accumulation to distinguish between stationary and moving objects, and applies contextual discounting for modeling information obsolescence. As a result, the method is able to better characterize the state of the occupied cells by differentiating moving objects, parked cars, urban infrastructure and buildings. Another advantage of this approach is its ability to separate the drivable from the non-drivable free space. Experiments carried out in real traffic conditions with a specially equipped car illustrate the performance of this approach.

Automation of information decision support to improve e-learning resources quality

Purpose. In conditions of active development of e-learning the high quality of e-learning resources is very important. Providing the high quality of e-learning resources in situation with mass higher education and rapid obsolescence of information requires the automation of information decision support for improving the quality of e-learning resources by development of decision support system. Methodology. The problem is solved by methods of artificial intelligence. The knowledge base of information structure of decision support system that is based on frame model of knowledge representation and inference production rules are developed. Findings. According to the results of the analysis of life cycle processes and requirements to the e-learning resources quality the information model of the structure of the knowledge base of the decision support system, the inference rules for the automatically generating of recommendations and the software implementation are developed. Practical value. It is established that the basic requirements for quality are performance, validity, reliability and manufacturability. It is shown that the using of a software implementation of decision support system for researched courses gives a growth of the quality according to the complex quality criteria. The information structure of a knowledge base system to support decision-making and rules of inference can be used by methodologists and content developers of learning systems.

Analysis of the joint use of the proactive and reactive methods of the topology information dissemination in ad-hoc wireless networks

A number of routing protocols for wireless ad-hoc (self-organizing) networks selects routes according to the topology information obtained by the station. Hence, the method of these protocols used to disseminate topology information strongly affects the network performance. An unsuccessful choice of the method can lead to a large amount of traffic and the information obsolescence. These factors diminish the network performance and make it impossible to meet quality of service requirements in transmitting realtime multimedia data, which is a topical problem. The routing protocol combining the proactive and reactive methods of the topology information dissemination has been proposed. It is demonstrated that this protocol is efficient in a wide range of scenarios applied to the exchange of real-time multimedia data.

Modular approach to modelling of higher education in information technology

In this paper, a modular approach is investigated – an educational response to the fundamental characteristics and requirements of the new era, whose main determinants are globalisation and networking, rapid technological development, information-based economy and the rapid obsolescence of information and knowledge. Education is one of the most important factors responsible for the development of society and its adaptation to changes brought by the information age is very important. In order to successfully achieve this adjustment, it is not enough to only change and update the content. It is equally important to make changes in teaching forms and methods. Modern education requires a new model of learning – active learning based on real-world information resources.

Towards a Logic of Perishable Propositions

Reasoning with uncertain information is a central issue for Artificial Intelligence and Information Systems. Consequently, a vast amount of studies and results devoted to this issue can be found in the literature. Curiously, reasoning with information whose uncertaintyvaries along time cannot be found so much in the literature. Dynamic reliability is a feature found rather frequently in many problems, e.g. in financial markets, meteorology and demographics. In this article we consider propositions whose information about truth evaluation is gradually lost with time. Our motivation has come from the information system under development within the project SIDAM--Distributed Information Systems for Mobile Agents (supported by FAPESP, grant 98/06138-2)--to provide citizens with information about urban automotive traffic in a large city. We propose functions of loss of information, and show how they can be used to characterize the obsolescence of propositional information in a logical system.

Matching intermediaries for information goods in the presence of direct search: an examination of switching costs and obsolescence of information

This paper investigates patterns of revenues earned by an intermediary that matches buyers and sellers in the presence of direct search markets. We develop a theoretical structure and a computer simulation model of such a marketplace where vendors are horizontally differentiated, and an intermediary matches clients to the optimal vendor for a fee. The model is applicable to information services such as application service providers (ASPs). The contribution of this paper is the identification of scenarios under which intermediaries that match clients and vendors are likely to be profitable considering switching costs and obsolescence of information.
