3D KARAKTER MODELLEMESİ VE ANİMASYONU AŞAMALARI

Author(s): Can Sahin / Language(s): Turkish / Issue: 55/2019

Technological developments, the computer and the products offered on the Digital Platform and the number of people using them are continuously increased. The power and impact of design are more effective in daily life than in the past, and their impact on individuals and societies is sharpening. Other materials, such as the computer we use in digital environments, should be considered as tools that help the designer to demonstrate their creative skills in the environments that they create. When a well thought-out idea is being digitized, the subject may become unwarranted due to the lack of technical skills, inability to dominate the technical equipment to be used, and the lack of cultural and ethical skills. It is important to note that the creative thinking and idea development of the work is also essential in the study area. Those who possess the power of technology and design can reach people and societies in different geographies to the extent they can control the rapid growth of this system. All people in every age group can be loaded with instantly accessible systems, especially with cartoon technology and desired cultural elements. We aim to consciously consume the individuals and societies with their analytical ideas about their own values.

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 Behavioral Economics Approach to Digitalisation – The Case of a Principles-based Taxonomy

Author(s): Julia M. Puaschunder,Dirk Beerbaum / Language(s): English / Publication Year: 0

A growing body of academic research in the field of behavioural economics, political science and psychology demonstrate how an invisible hand can nudge people’s decisions towards a preferred option. Contrary to the assumptions of the neoclassical economics, supporters of nudging argue that people have problems coping with a complex world, because of their limited knowledge and their restricted rationality. Technological improvement in the age of information has increased the possibilities to control the innocent social media users or penalise private investors and reap the benefits of their existence in hidden persuasion and discrimination. Nudging enables nudgers to plunder the simple uneducated and uninformed citizen and investor, who is neither aware of the nudging strategies nor able to oversee the tactics used by the nudgers (Puaschunder 2017a, b; 2018a, b). The nudgers are thereby legally protected by democratically assigned positions they hold. The law of motion of the nudging societies holds an unequal concentration of power of those who have access to compiled data and coding rules, relevant for political power and influencing the investor’s decision usefulness (Puaschunder 2017a, b; 2018a, b). This paper takes as a case the “transparency technology XBRL (eXtensible Business Reporting Language)” (Sunstein 2013, 20), which should make data more accessible as well as usable for private investors. It is part of the choice architecture on regulation by governments (Sunstein 2013). However, XBRL is bounded to a taxonomy (Piechocki and Felden 2007). Considering theoretical literature and field research, a representation issue (Beerbaum, Piechocki and Weber 2017) for principles-based accounting taxonomies exists, which intelligent machines applying Artificial Intelligence (AI) (Mwilu, Prat and Comyn-Wattiau 2015) nudge to facilitate decision usefulness. This paper conceptualizes ethical questions arising from the taxonomy engineering based on machine learning systems: Should the objective of the coding rule be to support or to influence human decision making or rational artificiality? This paper therefore advocates for a democratisation of information, education and transparency about nudges and coding rules (Puaschunder 2017a, b; 2018a, b).

A big data lehetséges szerepe a pártpreferencia-becslésekben magyarországi pártok és politikusok Facebook-oldalainak adatai alapján. Módszertani kísérlet

Author(s): Júlia Anna Koltai,Ádám Stefkovics / Language(s): Hungarian / Issue: 2/2018

Over the past few years, elections have shown worldwide that social media plays an increasingly important role in political life, both in politics and in the political activity of voters. Social media sites have become a new domain for the measurement of public opinion, offering many new opportunities. Discourses (such as tweets) and acts (such as likes) can form the basis for an election prediction. Compared to traditional prediction methods, big data-based research can be considerably cheaper and faster and can provide real-time tracking of public opinion. The aim of our paper is to gather international examples and showcase the success and failure of implementing them on Hungarian Facebook data and thus provide researchers with a basis for further investigations. In our analysis we examined whether there is a correlation between the number of likes that Hungarian parties and party leaders get on Facebook and the political poll results conducted in the same time period. The average number of likes per post proved to be the most appropriate indicator for party preferences, showing fairly good correlations in 7 of the measured 12 months. Beside this the indicator is quite volatile, and correlations differ between parties and party leaders.

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

Author(s): Lorena Clara 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 brief report on the relationship between self-control, video game addiction and academic achievement in normal and ADHD students

Author(s): Maryam Haghbin,Fatemeh Shaterian,Davood Hosseinzadeh,Mark D. Griffiths / Language(s): English / Issue: 4/2013

Over the last two decades, research into video game addiction has grown increasingly. The present research aimed to examine the relationship between video game addiction, self-control, and academic achievement of normal and ADHD high school students. Based on previous research it was hypothesized that (i) there would be a relationship between video game addiction, self-control and academic achievement (ii) video game addiction, self-control and academic achievement would differ between male and female students, and (iii) the relationship between video game addiction, self-control and academic achievement would differ between normal students and ADHD students. Methods: The research population comprised first grade high school students of Khomeini-Shahr (a city in the central part of Iran). From this population, a sample group of 339 students participated in the study. The survey included the Game Addiction Scale (Lemmens, Valkenburg & Peter, 2009), the Self-Control Scale (Tangney, Baumeister & Boone, 2004) and the ADHD Diagnostic checklist (Kessler et al., 2007). In addition to questions relating to basic demographic information, students’ Grade Point Average (GPA) for two terms was used for measuring their academic achievement. These hypotheses were examined using a regression analysis. Results: Among Iranian students, the relationship between video game addiction, self-control, and academic achievement differed between male and female students. However, the relationship between video game addiction, self-control, academic achievement, and type of student was not statistically significant. Conclusions: Although the results cannot demonstrate a causal relationship between video game use, video game addiction, and academic achievement, they suggest that high involvement in playing video games leaves less time for engaging in academic work.

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 Case Study of Software Product Line for Business Applications Changeability Prediction

Author(s): Zdravko Roško,Vjeran Strahonja / Language(s): English / Issue: 2/2014

The changeability, a sub-characteristic of maintainability, refers to the level of effort which is required to do modifications to a software product line (SPL) application component. Assuming dependencies between SPL application components and reference architecture implementation (a platform), this paper empirically investigates the relationship between 7 design metrics and changeability of 46 server components of a product line for business applications. In addition, we investigated the usefulness of Platform Responsibility (PR) metric as an indicator of product line component changeability. The results show that most of the design metrics are strongly related to the changeability of server component and also indicate statistically significant correlation between Maintainability Index (MI) and PR metric. The assessment is based on a case study of the implementation of the product line for business applications in a financial institution. The results show that PR metric can be used as good predictor of changeability in the software product line environment.

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 computer-based test item bank using a Rasch model

Author(s): Neil Jones / Language(s): English / Issue: 24/1990

This chapter describes a computer-based test item bank which I am developing for use in the English Language Centre of the University of Poznań. The system depends on a statistical analysis using a Rasch model, or Latent Trait theory. This is a recent and still relatively little-known approach to statistical analysis, and this paper will thus include an introduction to the probabilistic principles upon which it is based, and a brief discussion of the advantages claimed for it. Various computer programmes have been described for fitting the Rasch model to data. The item bank described uses a computerised version of a procedure for hand-working called PROX. Readers interested in actually using the statistics would need more guidance than the limited space here allows (e.g. Henning 1987). Therefore only the background to the statistics is described in this chapter.

A Conceptual Framework for Facility Management in Higher Education Institutions in Saudi Arabia

Author(s): Abdulaziz Alsayyari,Adel Alblawi,Mohammad Nawab,Ahmed Alosaimi / Language(s): English / Issue: 1/2019

A utilization of facility management (FM) practices may greatly simplify the process of managing and operating the facilities of higher education institutions. Thus, this paper presents a conceptual framework for effective and efficient operation and management of facilities of these institutions in the Kingdom of Saudi Arabia (KSA). This field of research is significant given that the top management at the Ministry of Education level in the KSA is concerned about the high cost of operational expenditures and cleaning contracts of universities. As a result, 8% percent of the financial support has been reduced in last two years. Yet, more reduction in the support is expected in the coming years, which necessitates a reconsideration of practices and restructuring of responsible departments. The ministry’s set of actions in this context is justified by the stringent goals mandated by the Saudi 2030 Vision and the National Transformation Program (NTP) to rationalize the expenditures of all government sectors. Therefore, this paper summarizes the current practices of FM in universities and identifies the opportunities and challenges they typically face. Given the common structure and regulations of the public universities in Saudi Arabia, this study takes Shaqra University (SU) as a sample study. Therefore, SU’s facilities were assessed through data collection and analysis.Additionally, interviews were conducted with the property and maintenance departments’ teams to understand the current management and operations practices being implemented at the university. The results show that SU professionals do not comply with the correct practices of FM. Practical implications of this work include setting up good practices for managing and operating higher education facilities, where the adaptation of the correct FM rules will improve the liability of the educational infrastructure.

A Conceptual Framework to Represent the Theoretical Domain of “Innovation Capability” in Organizations

Author(s): RamonB. Narcizo,Alberto G. Canen,Iara Tammela / Language(s): English / Issue: 1/2017

The term ‘innovation capability’ has been used recurrently in the innovation literature, but there is still considerable divergence about its meaning and implication to organizations. A consensus exists that, to innovate, organizations must possess innovation capability, and that the ownership of this feature is not a binary process, but rather an evolutionary level process. This evolutionary logic is analogous to the basic structure of organizational maturity models. However, the literature integrating innovation capability into a maturity perspective is still limited. Considering these premises, from a broad bibliographical research, this article presents a framework of reference to represent the entire theoretical domain of innovation capability. Its purpose is to classify the main types of models about this construct available in the reference literature. It is organized at increasing levels of complexity, so that each level creates the conceptual conditions for the construction of more comprehensive models. Similar to the main use cases for maturity models, there are three basic levels for the framework: descriptive; comparative; and, finally, prescriptive models of innovation capability. Considering this cumulative framework, the authors argue that, to be fully understood, innovation capability should be studied using the perspective of maturity models.

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 (32)/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.
