Despite the potential benefits of using an eModerate system in terms of optimising examination procedures, the implementation and application of such online moderation systems in the South African context is limited. Various factors could be contributing towards the resistance to the implementation and adoption of eModerate systems in higher education institutions. These factors include human factors as well as technical and organisational resistance to change. This study focuses on the human factors involved in eModeration (user experience) and attempts to answer the following research question: How can the User Experience Evaluation Framework for eModeration be utilised within the context of higher education institutions in South Africa? The research used a Design Science Research methodology, which included the design, development as well as testing of the User Experience Evaluation Framework for eModeration. This paper will report on identified issues pertaining to the User Experience Evaluation Framework for eModeration during the evaluation phase. The research was conducted at Midrand Graduate Institute (MGI), now trading as Pearson Institute of Higher Education, a private higher education institute in South Africa. The data generation methods included interviews with eModerators from different faculties within a private higher education institution. This paper makes a theoretical contribution to this area of study by identifying the problems that users might have with the implementation of the User Experience Evaluation Framework for eModeration as well as providing some insights into the user experience of eModerators.","PeriodicalId":256906,"journal":{"name":"2017 Conference on Information Communication Technology and Society (ICTAS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116305741","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}

Patients are encouraged to manage and control their own health data and information through the use of personal electronic health records (PEHRs). However, as this is a new type of electronic health record, there are concerns that must be addressed before patients make use of the technology. One of these concerns relate to using mobile devices to manage PEHRs, as patients fear that their health data may be breached due to the mobility and security concerns of these devices. The purpose of this paper is to investigate the information security controls that health care providers must put in place to protect PEHRs accessed from a mobile device. An inductive research approach was used which included an extensive literature review, while a thematic analysis of the data was used in identifying, analysing and reporting patterns within the data. The conceptual m-Health privacy framework was used to identify the 10 privacy principles for the mobile health platform and compared with the three distinct information security threats for the mobile platform. The study found that the data in transit was not as well protected by the framework, while the individual and database of the health care organisation was better regulated. The recommendation of the study is to improve the framework through the inclusion of specific information security controls to protect a patient's privacy whilst in transit when using PEHRs.","PeriodicalId":256906,"journal":{"name":"2017 Conference on Information Communication Technology and Society (ICTAS)","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122766447","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}

The present study investigates one category of bullies referred to as mobile bully-victims, looking at the evolution of adolescent mobile bully-victims across different ages in different schools which are in different geographical locations around Cape Town. Bully-victim behavior is prevalent during the adolescent stage; this is an era of transitioning and is said to be a stressful period which sees individuals developing impulsive behavior and constant changes in emotions. Structural Equation modelling was used to analyze how the mobile bully-victim pathways are formed. 407 mobile bully-victims, aged 14–18 years were surveyed. 107 of these bully-victims are from schools in low risk safety areas, 114 from moderate and the other 186 from schools in high safety risk areas. The results reveal declining mobile bully-victim behavior across the schools in the different areas, that is, schools in high safety risk zones have a higher rate of mobile bully-victims and those in low risk safety zones have lower rates. The results reveal that in low safety risk schools, previous traditional bullying only influences technology at ages 17 and above, which then leads to bully-victim behavior. In moderate to high safety risk areas, previous traditional bullying experience strongly predicts mobile bully-victim behavior as children grow. These findings are contrary to previous research, which shows that technology advancement in low safety risk areas would encourage more technology use among children thus resulting in irregular usage. The results also reveal that previous traditional bullying experience influences the lack of self-control and the tendency to retaliate which result in mobile bully-victim behavior across all ages in all three of the safety risk zones.","PeriodicalId":256906,"journal":{"name":"2017 Conference on Information Communication Technology and Society (ICTAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130939277","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, their batteries discharge quickly, even if they are not being used mainly because of the heavy computation tasks required by the multimedia applications that run on them. The quick turnover time on the battery life is problematic as frequent charging is required to keep the device operational. This is a major bottleneck because of the current energy optimization crisis, user inconvenience due to constant charging of battery and erratic nature of the electricity supply in some areas. In the current research project, the primary aspiration is to explore the energy harvesting technology innovation of radio frequency to wirelessly recharge the batteries of mobile devices. This implies an alternative way of charging the batteries of mobile devices without the need for a physical charger to connect to an electrical outlet. Energy harvesting, which involves making use of “free energy” from the atmosphere is the most innovative energy-efficient wireless charging technology because mobile devices are constantly transmitting radio signals. At first, radio signals are received from the atmosphere via an antenna. Thereafter, these signals are converted with a rectifier from alternating current into direct current that is then utilized to recharge the battery of a mobile device. The outcome of this phase of the research project is intended to successfully build a radio frequency harvesting circuit that can store a minimum load of 5mV that is required to charge the battery of a mobile device.","PeriodicalId":256906,"journal":{"name":"2017 Conference on Information Communication Technology and Society (ICTAS)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130502913","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}

People have used different types of currencies at different times throughout history. Commodity currencies represented items which are either mined from the Earth or produced by agriculture such as gold or salt. Fiat currencies are created by decree by a sovereign nation or groups of nations. Complementary currencies have been created by much smaller groups of people to solve problems which cannot be solved by commodity currencies or fiat currencies. For example, in times of economic depression when people attempt to hoard money (store wealth) there is often not enough currency to accommodate a means of exchange. With the advent of blockchains and crypto-currencies, it is now possible to easily create complementary currencies to attempt to solve problems which can not be solved using commodity currencies or fiat currencies. This paper discusses and compares two different architectures which are being used in two independent projects in South Africa to create complementary currencies by using the Ethereum blockchain and crypto-currency in order to encourage corporate excellence. It is important to note that this paper is not about the underlying success or failure of the complementary currencies created by the architectures. The paper is about the architectures themselves.","PeriodicalId":256906,"journal":{"name":"2017 Conference on Information Communication Technology and Society (ICTAS)","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121032363","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}

Adversely, the security and Defence role-players in developing countries, such as South Africa, are short of the required capacity and capability to adequately defend and protect the national cyberspace against these fast moving and persistent threats and attacks. Be that as it may, the South African cyberspace still requires national attention and protection by the mandated role-players, such as the Defence force and its industry partners. Thus, within the cyber domain, the various Defence force role-players can no longer rely on traditional solutions to detect, defend, and respond to the forever changing cyber threats and cyberattacks. In order to reduce cybersecurity risks and strengthen cyber resilience of the nation, strategic cybersecurity information sharing in the Defence environment is becoming a necessity. Thus, the contribution from this paper is a systematic discussion and demonstration of a conceptual cyber threat intelligence sharing model and platform that could stimulate and enable different stakeholders within the Defence environment to seamlessly and collaboratively aggregate, analyse, and timely share contextual and actionable cyber-threat intelligence that could lead to a resilient cybersecurity posture and better protection of the national cyberspace.","PeriodicalId":256906,"journal":{"name":"2017 Conference on Information Communication Technology and Society (ICTAS)","volume":"06 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130504562","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}
