Despite its many advantages, it is still in the early stage of implementation in Hong Kong. This may be due to the potential challenges such as learners’ limited participation and adaptation problems. The purpose of this article is to discuss the challenges based on Brame’s (2013) four key elements of the flipped classroom – exposure, incentive, assess, and activities. Particularly, we put emphasis on how teachers from Hong Kong higher education address the four aspects of challenges in their flipped classroom planning and design. Teachers of twenty-six courses in five universities in Hong Kong were invited to complete a teaching profile for their coming flipped courses which they were asked to elaborate their teaching goals and how they would execute the course. The teaching profiles revealed that the teachers devised a wealth of different strategies in implementing flipped classroom. We generalized their careful planning into eleven tips that can be seen as the collective wisdom of the teachers, as well as potential solutions to the flipped classroom challenges. This article summarizes the first phase of our study that eventually will examine the success factors of the flipped classroom approach in Hong Kong higher education.","PeriodicalId":245560,"journal":{"name":"IADIS INTERNATIONAL JOURNAL ON WWW/INTERNET","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123800083","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}

In comparing the data sets, the findings suggest that overall females were more likely to engage in online self-paced coding education, particularly when they had no background or previous study in an IT discipline. This contrasted strongly with females having an existing IT qualification. When looking at ethnicity, the research identified that those students who identify as an ethnic minority were more likely to undertake formal tertiary education in IT, rather than engage in online coding study. The research also confirmed that the average age was higher, and diversity of age groups was larger for those undertaking online study, when compared with those undertaking formal tertiary study. The practical implications of this analysis to diversity in Information Technology disciplines such as computer science, and more broadly with STEM-related disciplines are discussed.","PeriodicalId":245560,"journal":{"name":"IADIS INTERNATIONAL JOURNAL ON WWW/INTERNET","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132822713","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}

Many strategies have been proposed and implemented, however, the sophistication and rate of deployment of bot accounts is increasing rapidly. This impedes and limits the capabilities of detecting bot strategies. Various features broadly related to account profiles, tweet content, network and temporal patterns have been utilised in detection systems. Tweet content has been proven instrumental in this process, but limited to the terms and entities occurring. Given a set of tweets with no obvious pattern, can we distinguish contents produced by social bots from those of humans? What constitutes engagement on Twitter and how can we measure the intensity of engagement among Twitter users? Can we distinguish between bot and human accounts based on engagement intensity? These are important questions whose answer will improve how detection systems operate to combat malicious activities by effectively distinguishing between human and social bot accounts on Twitter. This study attempts to answer these questions by analysing the engagement intensity and lexical richness of tweets produced by human and social bot accounts using large, diverse datasets. Our results show a clear margin between the two classes in terms of engagement intensity and lexical richness. We found that it is extremely rare for a social bot to engage meaningfully with other users and that lexical features significantly improve the performance of classifying both account types. These are important dimensions to explore toward improving the effectiveness of detection systems in combating the menace of social bot accounts on Twitter.","PeriodicalId":245560,"journal":{"name":"IADIS INTERNATIONAL JOURNAL ON WWW/INTERNET","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127541610","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}

This lack of EHR integration prevents patients and physicians to have a unified view of medical records, which are often stored in different health organizations. Recent studies have proposed using Blockchain technology in distributed architectures due to its security and integration properties. In this context, this article proposes an application architecture using Blockchain technology for distributed EHR integration, which is called UniRec (Unified Medical Records). In the proposed model we seek to understand its effectivity, performance and applicability, using a case study methodology. We developed a prototype, which is evaluated using a test scenario. The prototype proved to be effective for distributed EHR integration, allowing one healthcare institution to view an EHR previously added by different providers, after being granted permission. During the test scenario execution, we obtained an average response time of 2.77 seconds, 961.6 MiB of memory consumption, 21.5% CPU usage and a total disk usage of 34.6 MB. The results reinforce the potential and feasibility of employing Blockchain for managing and storing medical data.","PeriodicalId":245560,"journal":{"name":"IADIS INTERNATIONAL JOURNAL ON WWW/INTERNET","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122184945","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}

However, the focus of existing research has not primarily been on the employees’ energy consumption behavior, albeit its potential impact on workplace energy efficiency. Aiming to affect employee energy behavior change towards more conscious consumption patterns, we have adopted gamification, a contemporary instrument that, when carefully utilized can lead to employee behavior change. Furthermore, we have followed an Iterative & Incremental Agile User Centered Design (UCD) approach towards designing a gamified IoT-enabled mobile app that provides energy consumption-related feedback to employees at their workplace. We present the characteristics of the designed app, as well as explain the rationale behind their choice. Usability results derived from employees in 3 workplaces at 3 different EU countries indicate that through our approach we designed a prototype gamified solution very well perceived and engaging to our target audience, scoring high in both usability, as well as user experience aspects. We further enhanced the app with additional functionality, according to the test users’ feedback, towards producing the first integrated version. Initial results from testing this revised first integrated version of the app, revealed even more enhanced usability and user experience results, compared to the previous version. Overall, our derived evidence suggests that, by following an Iterative & Incremental Agile UCD approach within our field of application, we have derived a gamified app for energy-saving at the workplace that is conceived of as highly usable and provides for a positive user experience.","PeriodicalId":245560,"journal":{"name":"IADIS INTERNATIONAL JOURNAL ON WWW/INTERNET","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123953649","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}
