Syntactic Method for Vehicles Movement Description and Analysis
No full textThe syntactic primitives and the description language can be used for assignment and analysis of vehicles movement. The paper introduces a method that allows spotting vehicles’ manoeuvres on and between traffic lanes, observing images, registered by a video camera. The analysis algorithms of the vehicles’ movement trajectories were considered in this paper as well
Theoretical difference between impact factor and influence factor
No full textBibliometric constructions of "knowledge maps" and "cognitive structures of science" do not differentiate between impact and influence factors. The difference can be constructedaccording to different meaning and interpretation of the terms reference and citation. Reference is "acknowledgment which one author gives to another", whereas citation is "acknowledgment which one document receives from another". Development of Information Science according to period and subject area is analyzed on the corpus of citation literature retrieved from doctoral dissertations in Information Science from 1978 to 2007 at Croatian universities. The research aim is to indicate the difference between document impact factor and author's influence factor (i.e. reference ability to produce effects on actions, behavior, and opinions of authors of doctoral theses). The influence factor serves to distinguish the key role of cited authors in time and according to the duration of the influence (the average age for cited papers of dominant authors in different periods is between eight and ten years). The difference between linear and interactive communication seems vital for the interpretation of cited half-life, i.e. the attitude of one science community towards used information resources and cognitive heritage. The analyzed corpus of 22,210 citations can be divided into three communication phases according to influence factor criteria: in the phase of dialogue and interactive communication 25% of bibliographic units are cited in the first four years; in the second phase another 25% of units are cited from the fifth to the ninth year; after ten years, in the dominant linear communication phase, approximately 30% of units are cited
eTourism: A comparison of online and offline bookings and the importance of hotel attributes
No full textInternet is an important tool for information searching and purchasing of products especially in tourism. This paper investigates the impact of demographic and travel characteristics of hotel guests on online and offline reservations. It also examines the importance of hotel attributes in selecting a hotel and the differences in priorities between guests who book their accommodation online and offline. Data was collected by surveys of guests in three hotels in Dubrovnik. The results of the study showed that the method of booking mostly depends on the nature of travel, and that the importance of hotel attributes does not differ much between different groups of guests
From the Editor
No full textDear authors, readers and future authors,I proudly introduce to you a new issue of JIOS, the Journal of Information and Organizational Sciences, volume 34, Issue 2. The Journal’s primary goal is to present current research in the field of information and organizational sciences, as well as on theoretical developments in the fields that impact information, computer and organizational sciences.The importance of JIOS is rising and it is being increasingly seen as a relevant journal in the eld of information sciences and applied information and communication technology. Speaking in favour of this statement is the fact that JIOS has been included into two new databases: Scopus and EBSCO. We are particularly satised with the Journal’s inclusion in Scopus since it is the largest abstract and citation database containing both peer-reviewed research literature and quality web sources.In this issue of JIOS a selection of four original scientic papers and one preliminary communication paper have been included that cover the following topics: approach to optical network design using a general heuristic optimization framework (Lackovic, M.), improving e-learning eciency, intelligence and adapted teaching materials (Kalpic, D. & Zuc, J.), online privacy (Mekovec, R.) and social network analysis of Eureka project partnership in Central and South-Eastern European regions (Divjak, B., Peharda P., Begicevic N.). We hope you will nd these papers interesting and challenging for your own research.I would hereby invite all the interested colleagues to submit a paper and hence contribute to the improvement and development of JIOS. You can submit your papers at jios.foi.hr, where you can also express your comments, recommendations or critical remarks regarding the papers published in previous issues
Fuzzy Linguistic Optimization on Multi-Attribute Machining
No full textMost existing multi-attribute optimization researches for the modern CNC (computer numerical control) turning industry were either accomplished within certain manufacturing circumstances, or achieved through numerous equipment operations. Therefore, a general deduction optimization scheme proposed is deemed to be necessary for the industry. In this paper, four parameters (cutting depth, feed rate, speed, tool nose runoff) with three levels (low, medium, high) are considered to optimize the multi-attribute (surface roughness, tool wear, and material removal rate) finish turning. Through FAHP (Fuzzy Analytic Hierarchy Process) with eighty intervals for each attribute, the weight of each attribute is evaluated from the paired comparison matrix constructed by the expert judgment. Additionally, twenty-seven fuzzy control rules using trapezoid membership function with respective to seventeen linguistic grades for each attribute are constructed. Considering thirty input and eighty output intervals, the defuzzifierion using center of gravity is thus completed. The TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is moreover utilized to integrate and evaluate the multiple machining attributes for the Taguchi experiment, and thus the optimum general deduction parameters can then be received. The confirmation experiment for optimum general deduction parameters is furthermore performed on an ECOCA-3807 CNC lathe. It is shown that the attributes from the fuzzy linguistic optimization parameters are all significantly advanced comparing to those from benchmark. This paper not only proposes a general deduction optimization scheme using orthogonal array, but also contributes the satisfactory fuzzy linguistic approach for multiple CNC turning attributes with profound insight
Personal Efficacy and Factors of Effective Learning Environment in Higher Education: Croatian and American Students
No full textSuccessful learning in higher education incorporates various factors related to knowledge, skills, habits, and motivation. Additionally, students’ personalities and self-efficacy may contribute to their adjustment, planning of activities, and achieving success. The objective of this paper is to analyze students’ needs for support services, which enhance the effectiveness of their learning environment at higher education institutions. Answers received from a sample of undergraduate freshmen at one American University and one Croatian University were analyzed and compared. The students from both countries agree that there is a need for developing self-reliance and personal responsibility in using support services, as well as for the timely and accurate information on availability of these services. Students’ suggestions and their desire to enhance effectiveness of their learning environment may be used in creating and improving support services in higher education institutions as well as training their staff
Strategic Analysis and Model Construction on Conflict Resolution with Motion Game Theory
No full textThis research uses the “Participating Observation Method” to observe the interaction between manufacturer and distributor negotiation strategies, determine the preference and expectation of participants, and establish a framework for this type of research. Then it sets up the “analysis framework of negotiation strategies” between the manufacturer and the distributor based on an analysis of the respective conditions, advantages, and disadvantages of the manufacturer and distributor. Thirdly, this study sets up a reward matrix of the strategy action game between the manufacturer and the distributor. Then establishes a set of feasible “negotiation models” based on the reward matrix of the strategy game between the both parties to observe how the manufacturer and the distributor make their own bargaining decisions in the situation of information asymmetry or exterior opportunity/threat. Finally, this study establishes a “multi-agent strategy game protocol system model” to solve the conflict resulting from the self-strategizing of both parties for their own interests, and to achieve the utmost efficiency in the negotiation
Generic icons – yes or no?
No full textThe information society has become increasingly dependant on programs that are subjected to frequent evolutive, basic and logical changes for a variety of reasons whereas the visual design of the program/program interface mostly remains the same or gets slightly modified. The development of technology has become to such an extent a commonplace that the use of redesigned programs implies icons that are visually acceptable although representing obsolete technologies and that are eventually hard to change due to the habits developed by the program users. The research presents a study into the personal preference as to a particular icon, “Save” for example, and into the perception of the visual identities of today's programs under the circumstance of program icons being not compliant with the technological state-of-the-art. Based on the obtained results, the survey that included students attending web design and media technician courses and ECDL course participants who come in contact with computers and programming tools for the first time should enlighten both teachers and designers of programming interfaces about the way of linking the formal knowledge with a constructivist approach to designing and redesigning programs
