"ETHICS BY MOVIE". AN ALTERNATIVE ETHICS TRAINING METHOD FOR FUTURE PROFESSIONALS. A PILOT STUDY AMONG ROMANIAN STUDENTS

Author(s): Daniela Tatiana AGHEORGHIESEI (CORODEANU),Vladimir POROCH / Language(s): English / Issue: 53/2016

The paper presents the results of an empirical research that explored the opinion of Romanian students from four different professional Master’s Degree programs, on the impact of applying the method that we have called “Ethics by Movie” (creating the students’ own video scenarios on an ethical topic in teams) on substantiating ethical knowledge, ethical attitude and ethical behavior. The final sample consisted of 395 respondents. The students appreciate several advantages of the above mentioned teaching and learning method (”an ideal practice for understanding a theoretical concept”, ”an interactive method of learning” that helped them ”to acquire ethical concepts more easily or to reflect more deeply on the importance which must be given to ethical behavior, on the consequences of unethical behavior”, etc). Our study might prove to be useful due to the fact that it revives attention to a complementary teaching method that can contribute to increasing awareness of the ethical issues around us, to learning ethical concepts in a more substantiated manner, to the need to solve the ethical dilemmas related to the fact that we must be solidarity in the fight against unethical actions and that, through everything we do, we can send out own ethical message.

#domovina, czyli hashtagowanie ojczyzny

Author(s): Ewa Wróblewska-Trochimiuk / Language(s): Polish / Issue: 1/2017

Hashtags, originally introduced in Internet Relay Chat, then popularized in Twitter, have become the most used way to tag short messages in social networks. They are also used on Instagram since this facilitates searching, classification and clustering over visual materials. The text focuses on the hashtag domovina (homeland) and shows how Croatian users of Instagram understand and visualize the idea of homeland. I distinguished main strategies of understanding of homeland: by connecting it with national symbols, confession, landscape, cuisine and – unexpectedly – selfie. I find that Instagram group using the hashtag domovina is a new type of political community. In the last part of the text I state that images containing tag domovina create the thematic collection and that they form a new type of image that I called modern polyptych.

(MULTI)MEDIA LITERACY – PERSPECTIVES IN SERBIA

Author(s): Dejan Pralica / Language(s): English / Issue: 02/2016

The aim of this paper is to analyze the effects of media literacy in Serbia five years after "The Strategy for the Development of the Public Information System in the Republic of Serbia" came into force. Among other things, the "Strategy" proclaimed the introduction of new ICTs in order to contribute to better informing and education for children and youth. "Medijska koalicija" ("Media coalition") and US Agency for International Development (USAID), with the help of Serbian Ministry of Education and Science, started the project in order to encourage and support the democratization of the society via promotion of media literacy and responsible journalism in the Republic of Serbia. The target groups of the project were both teachers and secondary school students, as well as journalists. The project resulted in many seminars as well as a web-site which provide permanent support for the establishment of critical understanding of media messages using the most up-to-date learning models such as webinars and other multimedia tools.

A 3-FACTOR MODEL RELATING COMMUNICATION TO RISK MITIGATION OF EXTENDED INFORMATION SYSTEM FAILOVER

Author(s): Athanasios Podaras / Language(s): English / Issue: 2/2015

This paper aims to analyse the relation between timely and effective communication and risk mitigation of late recovery after an unexpected information system outage in enterprises. An unforeseen information system failure in modern enterprise units, may result to significant operational and financial damage. In such a critical incident, effective communication between the team leaders and the recovery team involved, can minimize or even eliminate this negative impact. An extended information system outage can be perceived as a time deviation from the Maximum Accepted Outage (ΜΑΟ) timeframe, proposed by the business continuity management, according to the value of which dependent business functions may be interrupted without any serious effects to the company. The paper examines the relation between 3 basic factors and the efficient communication between team members. The factors are: timely information distribution, staff availability and network availability. Through the current paper, the author proposes a risk analysis model, based on the Composite Risk Index theory of Risk Management, which can significantly diminish the possibility of an extended information system outage, as well as calculate the extended time required to recover a system when the aforementioned factors emerge in their worst form. The precise calculation of recovery time can be achieved via the execution of business continuity tests which include scenarios, according to which an unexpected system outage coexists with delayed information distribution as well as low staff and network availability.

A BLENDED-LEARNING APPROACH TO ESP TEACHING: DESIGNING A VIRTUAL PLATFORM

Author(s): Lorena Mihaes,Anda Dimitriu,Irina BOCIANU / Language(s): English / Issue: 03/2016

The demand for English courses particularly tailored to specific needs is ever growing in today’s higher education system. We teach a generation of undergraduate students who will most likely use English as a medium of instruction for their master’s degree, whether they decide to apply for one in Romania (the University of Bucharest offers 20 such programmes) or abroad. A greater emphasis, therefore, should be laid on meeting the competence standards required by the Common European Framework of Reference for Languages, so that, upon graduation, the student will be an independent user of general English and have a good mastery of the terminology of his field of study. Since the undergraduate English course spans anywhere from two to five or six semesters, during which time the instructors have the task of bringing students with various language levels up to the same proficiency par - when they would ideally be able to apply for the abovementioned postgraduate programmes, a solution to the problem is offered by digital technologies, which can complement the traditional teaching methods already in use. Based on students’ answers to a questionnaire which led us to conclude that not only are they conversant with the new technologies, but they also consider that their language skills would improve, should the virtual medium be used during the in-class activities, we have devised a rough draft of an online platform specifically designed to facilitate the students’ access to and assimilation of information through online applications.

A Business Analytics Shell for Teaching Corporate Decision Making

Author(s): Vladimir Zlatev / Language(s): English / Issue: 1/2014

This paper presents a new approach to the emerging educational curricula of big data business analytics and the needs to teach students how to use data effectively to drive rapid, precise, and profitable analytics-based decisions. The framework consists of interlinked data-inputs, analytics models, and decision-support tools integrated within a proprietary business analytics shell. We demonstrate the capabilities of the system on examples from different functional areas of the enterprise. The objective is to teach students how decision making is enhanced through analytic methods that integrate the volume, velocity, variety, and veracity of the internal and external information into analytics-based decisions. The business analytics shell uses Power BI, a cloud based Add-Ins, that works with Microsoft Excel 2013 and allows users to share, collaborate, and contribute to complex projects and business reports from anywhere on any devices. All analytics models are fully integrated within the business analytics shell. The decision-support tool is presented as a dynamic business simulation called ’Strategies and Decision Support in Organizations’, designed to illustrate the decision- making process on business and functional levels. The results from this approach allow participants in graduate management courses to better understand how managers measure and evaluate critical functions of their business and prepare them to participate and contribute in a more efficient way to the new challenges and opportunities facing the modern enterprise.

A Comparative Analysis of University Information Systems within the Scope of the Information Security Risks

Author(s): Rustu Yilmaz,Yildiray Yalman / Language(s): English / Issue: 2/2016

Universities are the leading institutions that are the sources of educated human population who both produce information and ensure to develop new products and new services by using information effectively, and who are needed in every area. Therefore, universities are expected to be institutions where information and information management are used efficiently. In the present study, the topics such as infrastructure, operation, application, information, policy and human-based information security at universities were examined within the scope of the information security standards which are highly required and intended to be available at each university today, and then a comparative analysis was conducted specific to Turkey. Within the present study, the Microsoft Security Assessment Tool developed by Microsoft was used as the risk analysis tool. The analyses aim to enable the universities to compare their information systems with the information systems of other universities within the scope of the information security awareness, and to make suggestions in this regard.

A conceptual model for data quality management in a data system on the World Wide Web

Author(s): Adam Czerwinski / Language(s): English / Issue: 4/2014

The article presents a conceptual model for data quality management treated as the usability or the compliance of the data product with its specification. The proposed model refers to the well-known TDQM model of Wang based on the Deming's quality improvement cycle. However, the TDQM model does not take into account the impact of the Internet environment on the quality of the data provided by the systems on the Web. The author's model presented in this article takes into account the impact of the Internet on all aspects resulting from data functions in society and organizations. Therefore, it takes into consideration the aspect of promoting data quality management processes, the communication aspect and the aspect of enrichment of individual and collective knowledge. The model also takes into account the fact that the impact of the known properties of the Internet (defined with the acronym MEDIA for example) refers primarily to the contextual quality characteristics of the data on the Web and, only to a small degree, it concerns the internal quality of information pieces described by such features as accuracy, consistency, complexity and precision.

A CRITICAL OVERVIEW OF THE DIGITAL KNOWLEDGE COMMONS FROM A MARXIST PERSPECTIVE

Author(s): FAITH AGOSTINONE-WILSON / Language(s): English / Issue: 6/2016

Going beyond a traditional understanding of commons as land and resources, a knowledge commons involves collective, cumulative informal experience, scientific research, the arts, and procedural, practical information, often with economic implications. However, much confusion exists around the terminology of today’s knowledge commons. This article clarifies the differences between open source and free software movements and provides an examination of copyleft and what it means for academics and activists. The author connects these movements to a Marxian vision of a knowledge commons for all.

A Data Pre-Processing Model for the TOPSIS Method

Author(s): Andrzej Kobryn,Joanna Prystrom / Language(s): English / Issue: 2/2016

TOPSIS is one of the most popular methods of multi-criteria decision making (MCDM). Its fundamental role is the establishment of chosen alternatives ranking based on their distance from the ideal and negativeideal solution. There are three primary versions of the TOPSIS method distinguished: classical, interval and fuzzy, where calculation algorithms are adjusted to the character of input rating decision-making alternatives (real numbers, interval data or fuzzy numbers). Various, specialist publications present descriptions on the use of particular versions of the TOPSIS method in the decision-making process, particularly popular is the fuzzy version. However, it should be noticed, that depending on the character of accepted criteria – rating of alternatives can have a heterogeneous character. The present paper suggests the means of proceeding in the situation when the set of criteria covers characteristic criteria for each of the mentioned versions of TOPSIS, as a result of which the rating of the alternatives is vague. The calculation procedure has been illustrated by an adequate numerical example.

A Dimensioning Methodology for a Natural Draft Wet Cooling Tower

Author(s): Ioana Opris,Victor-Eduard Cenu?a,George Darie / Language(s): English / Issue: 2/2017

The paper proposes a methodology for thedimensioning of a natural draft wet cooling tower. Themain geometrical dimensions depend on the packingtype, the cooling and the weather conditions. The studyis based on splitting the tower in three main zones: thespray and packing zone, the rain zone and the naturaldraft zone. The methodology is developed on modularbases, by using block-modules both for the three mainzones of the cooling tower and for the inlet/outlet airproperties. It is useful in explaining to the students thecomplex physical phenomena within the cooling towerbut also for the development of a computer program tobe used in engineering, management and education.

A Distributed Rule Mining Algorithm Based on Fp-Tree

Author(s): Jae Young Lee / Language(s): English / Issue: 1/2009

Mining global association rules from a distributed system is a challenging task. A solution must be not only computationally efficient but also scalable to potentially very large distributed systems. There have been some distributed association rule mining algorithms reported in the literature, all of which are based on Apriori. Using these algorithms, the communication overhead increases as the number of local databases increases. In this paper we propose a scalable algorithm, called DFPT, which is based on FP-tree. One important characteristic of DFPT is that communication cost scales primarily with the size of local databases and not with the number of local databases. So, increasing the number of local databases in the whole system does not significantly increase the communication cost. DFPT is especially suitable for a system that consists of a very large number of local databases, each of which is of moderate size, such as a network of a large number of small computers or a peer-to-peer system.

A Family of Two-Weight Ring Codes and Strongly Regular Graphs

Author(s): Ivan Landjev,Stoyan Boev / Language(s): English / Issue: 1/2009

It has been proved by Byrne, Greferath and Honold that a linear code over a finite Frobenius ring having exactly two homogeneous weights gives rise to a strongly regular graph. Up to now, only three infinite families of such codes are known. In this paper, we construct a new family of (homogeneous) two-weight linear codes over arbitrary chain rings of nilpotency index 2. These codes are defined geometrically as sets of points in certain projective Hjelmslev geometries. They provide a new example of an infinite class of two-weight codes over finite chain rings and produce an infinite family of strongly regular graphs.

A Fingerprint-Based Scheme for ATM User Authentication

Author(s): Gabriel B. IWASOKUN / Language(s): English / Issue: 2/2016

Presently, ATM users rely on the card-based information for authorization. This approach is confronted with challenges of card swallowing, misplacement, damage and expiration as well as Personal Identification Number (PIN) forgetfulness and theft. With a view to addressing these challenges, a fingerprint-based scheme for ATM user authentication is proposed in this paper. The scheme comprises of different components for fingerprint enrollment, database and verification. The verification component handles fingerprint enhancement, feature extraction and matching (based on suitable mathematical models). Validation experiments based on False Rejection Rate (FRR), False Acceptance Rate (FAR), Average Matching Time (AMT), Receiver Operating Characteristic (ROC) curve and Equal Error Rate (ERR) were conducted using FVC2000, FVC2002 and FVC2004 standard fingerprint databases. Comparative analysis of the experimental results with those obtained from three other schemes shows the superiority, adequacy and practicality of the proposed scheme.
