This article analyses the relation between job insecurity, job satisfaction and organizational commitment among employees of companies working in the tourism sector in Novi Sad, Serbia. The article aims to discover whether and to what extent there is a relation between these three variables, drawing on theoretical approaches and a questionnaire conducted in Novi Sad in 2012/2013 on a sample of 149 respondents in companies involved in tourism (hotels, tourist agencies and restaurants). The results indicate that there are strong positive correlations between organizational commitment and the variables which measure job satisfaction, while job insecurity correlates negatively with the variables which describe job satisfaction and organizational commitment.

The accelerated development of Information and Communications Technology has had a profound impact on the education system, both online and offline. In a South East European country such as Serbia, new technologies shape information, communication, and collaboration dynamics while contributing to a persistent digital divide regarding the skills necessary to obtain, process, evaluate, and communicate information. In this article, we explore digital divides between students and teachers in higher education with a focus on tensions surrounding digital literacy and collaboration. We apply Weber's theory of stratification to an empirical case study of the digital divide in higher education in Serbia. We draw upon international indicators, secondary statistical sources, and primary semistructured interviews with students and teachers in higher education. Through this analysis, we illustrate how forms of stratification intervene when trying to integrate new technologies and technology-oriented practices into the classroom. We consider stratification in terms of the traditional digital divide of access as well as stratification along lines of status, politics, and motivations. We interpret educators' reluctance to adopt new technology as a reaction to the technology's capacity to challenge the educators' legitimacy, expertise, and preferred teaching materials. Students compound this situation with both greater familiarity and yet less focus on source credibility.

Manufacturers have to look constantly for new strategies and tools to improve processes, decrease cost and increase productivity and efficiency. Production scheduling is one of the crucial elements in manufacturing and has an impact on delivery deadlines and also on the production process in terms of its utilization. On the other hand, the value stream optimization is very important for lean manufacturing efforts. This paper is aimed to research the impact of job shop scheduling on value stream optimization and decreasing of cost-time investment. Value stream mapping represents a very efficient tool for visualization of activities within production flow focused on activity duration with the purpose to eliminate non-value added activities. Value stream costing is based on value stream and eliminates the need for overhead allocation and calculation. Cost-time profile is a powerful tool for visualization and calculation of cost accumulation during the time across the entire manufacturing flow. Software tools used in this paper are: Lekin scheduling system for constructing the schedules based on four different dispatching rules and Cost-Time Profiler software for simulating the impact of different schedules on total production cost and cost-time investment (representing the time value of money), which is proposed as a new scheduling objective function.

PurposeThis research aimed to explore whether different project management approaches (traditional, agile or hybrid) differentiate concerning their impact on project success, taking project success as multidimensional phenomena. In addition to this, the authors wanted to explore if specific project characteristics moderate these effects.Design/methodology/approachThe authors empirically addressed these on a sample of 227 project professionals worldwide. The exploratory factor analysis (EFA) of project success dimensions was done to validate these factors' constitution concerning their manifest variables. The K-means cluster method was used to distinguish respondents' profiles among agile, hybrid and traditional project management approaches. To test the significance among research groups, the research hypotheses were tested with ANOVA tests.FindingsThe authors evidenced that the agile approach has a more significant positive impact concerning the two out of five dimensions of project success, under analysis in this research (impact on the team and preparing for the future), over the traditional approach.Practical implicationsThe research is relevant for project management practitioners to tailor the success-oriented project management approach and for academics to develop project management contingency theory.Originality/valueThe authors constructed a research framework to test the impact and effectiveness of different project management approaches (traditional, agile, hybrid) on the dimensions of project success in different contextual conditions (organization industry, project type, novelty, technology, complexity and pace). The paper's main contribution is to expand data on the impact of these approaches on project success and compare them with relevant results and findings of previous research.
