This tool allows near real-time analysis and visualization of online social environments. We propose that with automated methods an instructor can better evaluate the evolving social dynamics of an online classroom and intervene if necessary. In our design, we have two major approaches: The analysis of the social network using mathematical methods, which is based on existing research on SNA, and the design of an automated analysis and visualization tool. In this tool we combine both of these approaches into one fully automated workflow that downloads, processes and visualizes the SNA results.","PeriodicalId":316788,"journal":{"name":"International Conference on Computer Systems and Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114325252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After reviewing the currently predominant programming paradigms adopted in introductory programming courses and describing our approach based on decades of teaching practice, we present our recent experience in changing the first programming language from Modula-2 to Java. The question we focus on is whether there are any significant differences in student success between the most recent generation taught in Java, and previous Modula-2 generations. Statistical analysis of collected scores and grades can provide insight into the effects of the change of language since there were not many other factors distinguishing the generations. Comparisons involving two non-parametric statistical tests showed that there are no statistically significant differences between the considered generations with respect to success in passing the exam. This result suggests that the choice of the introductory programming language does not matter if we use students' performance as the criterion of suitability.","PeriodicalId":316788,"journal":{"name":"International Conference on Computer Systems and Technologies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122669814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although in recent years the business intelligence and analytics has gained an increasing amount of interest among researchers and practitioners, there is a little available academic literature available related on MBI's specific topic. We suppose that the importance and benefits of using mobile business intelligence systems are not recognized in small and medium enterprises (SME) in Croatia and the main obstacle for their adoption is the lack of funds and knowledge of the executives and users. The aim of this research is to explore the level of mobile business intelligence systems adoption in SME in Croatia, compare the obtained results with those founded in existing literature and to explore the ways that the executives perceive the specificities of MBI.","PeriodicalId":316788,"journal":{"name":"International Conference on Computer Systems and Technologies","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115919906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is often said that many of these have a poor reputation with many sections of academia and industry. Whilst there may be many publicized business advantages of using standards, standardization is an often-neglected route for exploiting academic and commercial research. Often researchers have little experience of standardization to plan, implement and exploit their research utilizing standards. Involvement with standards development organizations in your research can positively increase international recognition and highlight in a world stage your research and enhance your international reputation. This keynote address examined the benefits of being directly involved in the standards community for both industry and academia and specifically how standards can inform your research. Based upon personal experience as Ireland Head of Delegation to ISO's Software and Systems Engineering group and that of being an ISO standards editor, this keynote will examine the issues and benefits of becoming actively involved inside the standardization community and how this can be translated into your personal research agenda.","PeriodicalId":316788,"journal":{"name":"International Conference on Computer Systems and Technologies","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123036995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
