RETHINKING OF ENTREPRENEURSHIP: TOWARDS SOCIAL RESPONSIBILITY
No full textSocial entrepreneurship is highlighted as a result of general entrepreneurship development because the traditional entrepreneurial factors are accomplished with the social aspects of common good. Entrepreneur's responsibility in choosing the main business activity within an industry increases if the way he conducts his activities is considered. Institutional support for social entrepreneurship is achieved by generating many business activities in order to fulfil different kinds of social needs. Social entrepreneurship is possible if both entrepreneur’s initiative and institutional support for small and medium sized enterprises (SME) are included in performing for traditionally non-profit activities. Allowing private initiative to fulfil the real needs of different users in social, educational, cultural and other non-profit fields is a good way to support SMEs. However, the institutional control should still remain in place in order to protect the minimum performing standards.The development of social entrepreneurship in transition countries is important for general economic development, but also for the supporting values of ethics in business activities
PRIORITISATION OF E-LEARNING FORMS BASED ON PAIR-WISE COMPARISONS
No full textThere are different forms of teaching using ICT, and they differ according to the level of technological support, the role and tasks of the participants, the level of students’ participation, the physical location of the participants and their interaction. Distance learning is the common name for the process of obtaining knowledge and skills with the assistance of ICT and other forms of distance study. E-learning is a special form of such teaching. In terms of the teaching materials’ specific qualities, and the recommendation of teaching methods for successful teaching, there are different options for applying e-learning in teaching. E-learning can be used either as an independent form of teaching, or as a support to the already established systems of education, or even as their addition. The problem that is being solved in this paper is the prioritisation of e-learning forms for the specific teaching unit, subject, group of subjects, or the whole teaching programme. All this should be done regarding the context, which is characterised by the quality and innovative teaching, available professionals, equipment, possibility of students’ approach to technology, organization of teaching, and rules and regulations. This problem was solved with the assistance of AHP models developed in the process of group decision making supported by sw TeamEC2000
IDENTIFICATION OF THE FREQUENCY AND THE INTENSITY OF THE THREATS IN THE FUNCTION OF DEVELOPMENT OF THE INFORMATION SYSTEM
No full textIn the process of development of the security system of the information system, the risk assessment is the foundation for selection of the security measures. The reduction of the level of risk and the amount of costs depend upon the adequate selection of the security measures. The quality of the risk assessment depends upon the adequate assessment of the form and the intensity of the threats. If the forms of threats are not monitored in the business system, it should make its own threat assessment, or use experience of others. The best, but also the most time-consuming solution is to develop own security system, while the fastest way is to use experience of others. However, there is the problem of migration of some other solution to our own system. Depending upon the question whether we are adopting the experiences of domestic or foreign business systems, the question of the applicability to the system from the different business environment becomes relevant. This happens because of the significant differences in the form and intensity of threats in certain local environments or different branches of industry
EVALUATION OF ARIS AND ZACHMAN FRAMEWORKS AS ENTERPRISE ARCHITECTURES
No full textThe significance of integral business systems based on closer alignment of information technology to business processes has grown over the last ten years. Comprehensive business frameworks are necessary to capture the entire complexity of such systems. These frameworks called enterprise architectures can provide the conceptual foundation necessary for building and managing the integral business system and all its components. The goal of this paper was to analyze the Architecture of Integrated Information Systems (ARIS) and the Zachman frameworks, to define the criteria for comparison and evaluation of these approaches, and determine their level of complement. Furthermore, the contents of the paper define the generic model of business system management supported by said concepts (frameworks) and analyzes their orientation towards value
A SURVEY OF THE PROPERTIES OF AGENTS
No full textIn the past decade agent systems were considered to be as one of the major fields of study in Artificial Intelligence (AI) field. Many different definitions of agents were presented and several different approaches describing agency can be distinguished. While some authors have tried to define “what” an agent really is, others have tried to identify agents by means of properties which they should possess. Most authors agree on these properties (at least basic set of properties) which are intrinsic to agents. Since agent's definitions are not consistent, we are going to give an overview and list the properties intrinsic to an agent. Many different adjectives were attached to the term agent as well and many different kinds of agents and different architectures emerged too. The aim of this paper it go give an overview of what was going on in the field while taking into consideration main streams and projects. We will also present some guidelines important when modelling agent systems and say something about security issues. Also, some existing problems which restrict the wider usage of agents will be mentioned too
REASONING ABOUT THE GAME „CLUE“ BY USING OTTER
No full textIn this article the possibilities of reasoning about the card version of the game Clue by using OTTER - system for automatic theorem proving have been presented. The game Clue, as game based on knowledge have been modelled by PVETO logic - propositional multi-modal epistemic logic with temporal parameter adapted for reasoning with OTTER. PVETO logic is an extension of S5m logic and it’s most important characteristics are the introduction of special derivation predicates for every participant in the card game and introduction of temporal parameter. Temporal parameter refers to the moment of time in which we follow the truthfulness of the epistemic formulae
THE MODEL OF THE DOCUMENT MANAGEMENT SYSTEM IN THE PUBLIC SECTOR
No full textModern solutions regarding the use of unstructured information are based on the concept of Content Management (CM), [08] and [09]. This is a good solution for those document contents that will be generated once the CM is in place, but the question remains of what to do with hundreds of millions of documents that have been generated over the course of many years in the public sector. This article analyzes some of the features of the existing document systems in the public sector, and then discusses the needs of business processes reengineering, which are concerned with generating official decisions of relevance for both individual and business end-users. Furthermore, we propose a practically feasible model for the Document Management Systems (DMS) design, based on modern information and communication technologies that can manage and support the use of documents already in the system. In the end, this article takes a look at a general model for the calculation of costs and benefits associated with an introducton of a new DMS
SELECTING NEURAL NETWORK ARCHITECTURE FOR INVESTMENT PROFITABILITY PREDICTIONS
No full textIn this paper we present a modified neural network architecture and an algorithm that enables neural networks to learn vectors in accordance to user designed sequences or graph structures. This enables us to use the modified network algorithm to identify, generate or complete specified patterns that are learned in the training phase. The algorithm is based on the idea that neural networks in the human neurocortex represent a distributed memory of sequences that are stored in invariant hierarchical form with associative access. The algorithm was tested on our custom built simulator that supports the usage of our ADT neural network with standard backpropagation and our custom built training algorithms, and it proved to be useful and successful in modelling graphs
HOW TO CALCULATE INFORMATION VALUE FOR EFFECTIVE SECURITY RISK ASSESSMENT
No full textThe actual problem of information security (infosec) risk assessment is determining the value of information property or asset. This is particularly manifested through the use of quantitative methodology in which it is necessary to state the information value in quantitative sizes. The aim of this paper is to describe the evaluation possibilities of business information values, and the criteria needed for determining importance of information. For this purpose, the dimensions of information values will be determined and the ways used to present the importance of information contents will be studied. There are two basic approaches that can be used in evaluation: qualitative and quantitative. Often they are combined to determine forms of information content. The proposed criterion is the three-dimension model, which combines the existing experiences (i.e. possible solutions for information value assessment) with our own criteria. An attempt for structuring information value in a business environment will be made as well
IMPROVED VIRTUAL CIRCUIT ROUTING ALGORITHM FOR WIRELESS SENSOR NETWORKS UNDER THE ASPECT OF POWER AWARENESS
No full textRouting algorithms have shown their importance in the power aware wireless micro-sensor networks. In this paper first we present virtual circuit algorithm (VCRA), a routing algorithm for wireless sensor networks. We analyze the power utilized by nodes to lengthen the battery life and thus improving the lifetime of wireless sensor network. We discuss VCRA in comparison with the Multihoprouter, an algorithm developed by UC Berkeley. Then we present Improved Virtual Circuit Routing Algorithm (IVCRA) which is an improved form of VCRA. In IVCRA node failure detection and path repairing scheme has been implemented. We also present the energy analysis of IVCRA and prove that IVCRA is the best choice. We first implement our routing algorithms in simulator TOSSIM and then on real hardware of mica2 mote-sensor network platform and prove the reliable routing of the data packets from different nodes to the base station. The motes used as nodes in our mote-sensor network are from Berkeley USA. By using simulator POWERTOSSIM, we estimate and present the energy utilized by different nodes of the network. At the end we present a comparison of our work with the network layer of Zigbee/IEEE 802.15.4, which is an emerging standard for wireless sensor networks and then compare its energy efficiency with the packet size chosen for our algorithm
