The group we focus on here is composed of the elderly in developing countries. To inform specialised design, researchers produce and refine sets of tailored guidelines. In this case there is surprisingly little empirical evidence attesting to the value or efficacy of such guidelines. Corroborating evidence, in the form of endorsements of designs that have resulted from their implementation, would constitute such evidence. The aim of this paper is to evaluate existing mobile interface design guidelines for the elderly in developing countries by means of implementation. Guided by the design science research methodology, published guidelines were used to design and implement a mobile phone interface tailored to the needs of elderly South Africans. The resulting prototype was evaluated with two groups of South African elderly mobile phone users. Besides validating and refining the guidelines, the challenges experienced in implementing guidelines were noted together with some conclusions about the viability and usefulness of the specific guidelines, as well as mobile interface design guidelines in general. The unique contribution of this paper lies in the reflection on crossing the research-action divide by also considering the challenges of the developers in implementing the guidelines.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114215668","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}

Findings reveal that norms of email use, facilitated by the capabilities of this medium, exacerbate existing issues within the organisation such as conflict between management and operational level officers, and the view that bureaucracy related to increasing levels of accountability leads to feelings of overload and stress, and prevents officers from carrying out 'real police work'.\u0000 The paper reflects on the maintenance of social norms, even in conditions where the behaviour may not be considered appropriate by all members of the group, with implications for further research in this area. The paper argues that norms of email use are perceived as inappropriate by the officers, but that these officers are constrained by and maintain these norms despite this. Results show the importance of considering the interaction between media capabilities, organisational conditions and social norms of use in understanding the consequences of email use within organisational contexts.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121885264","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 growth has been evidenced by organisations continually aligning project activities with business strategy to achieve their strategic goals and create value for their organisations. Some of these initiatives are managed as IT projects. In 2016 the global information technology (IT) spend is forecast to total US$3.54 trillion. Despite this growth in IT investment, IT projects still fail at an alarming rate. These failed IT projects have resulted in organisations not achieving their strategic objectives and goals, in addition to costing them huge amounts of money. Many factors contribute to IT projects failing, such as a poorly defined project scope, insufficient human resources, cost overruns, poor communication among project stakeholders, project auditing practices not being followed, inadequate practices in project risk management and lack of correct auditing of processes in IT projects. The majority of project audits are based on ad hoc management requests rather than systematic auditing processes throughout the project life cycle. Project managers are still challenged on managing IT projects to successful delivery. The problem addressed in this article is the lack of IT project auditing processes throughout the project life cycle to ensure IT project success. A conceptual framework is proposed for IT project auditing assurance throughout the project life cycle. The framework introduces high-level and detailed IT project assurance processes in each assurance review gate. These processes can be tailored to ensure the successful delivery of an IT project. The benefits of this article are its contribution to the body of knowledge with regard to project auditing. Secondly, practitioners and project managers can use this framework to audit IT projects to ensure successful completion of IT projects.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121347291","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}

These overlapping issues highlight a disconnect in the perspectives held between health scientists' focus on the application of behaviour change theories and components of interventions, and the information systems designers' focus on the application of persuasive design principles as software design features intended to motivate, facilitate and support individuals through the behaviour change process. A review of the current status and some examples of these different perspectives is presented, leading to the identification of the main issues associated with this disconnection. The main behaviour change technique issues identified are concerned with: the fragmented integration of techniques, hindrances in successful use, diversity of user needs and preferences, and the informational flow and presentation. The main persuasive design issues identified are associated with: the fragmented application of persuasive design principles, hindrances in successful usage, diversity of user needs and preferences, informational flow and presentation, the lack of pragmatic guidance for application designers, and the maintenance of immersive user interactions and engagements. Given the common overlap across four of the identified issues, it is concluded that a methodological approach for integrating these two perspectives, and their associated issues, into a consolidated framework is necessary to address the apparent disconnect between these two independently-established, yet complementary fields.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117225129","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, many components require the services of other components to provide their functionality. In order to decouple the component being tested from its dependencies, one commonly uses mock objects. Mocking frameworks which are currently used in industry use dynamic mock object generation with the mocking behaviour specified where the mocking is required, e.g. within unit tests. There is no guarantee that the mocking behaviour is consistent with the behaviour required from the component being mocked. Furthermore, these mock objects are not reused across unit tests and other areas where mocking is required.\u0000 We consider an alternative approach to mocking where the mock object is specified against the contract being mocked and reused across unit tests and other code where mocking is required. These mock objects are tested against the component contracts for the components they are mocking. Furthermore, using dependency injection one is able to reuse the functional tests across unit tests (injecting mock objects for the dependencies) and integration tests (injecting actual components for the dependencies). Even though this approach does require more code to be developed for specifying mocking behaviour, this is offset by the mock object being reused across unit tests for components with the same dependency as well as across integration tests.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116675643","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}

While ICT has demonstrated a potential of curbing corruption, the factors influencing its efficiency have not been validated empirically. This study investigates the factors influencing ICT efficiency in curbing corruption in 52 African countries over a period from 2005 to 2014. Using Data Envelopment Analysis and Regression Analysis, technical efficiency scores were used as a dependent variable of corruption. Unlike other traditional regressions, the present study adopted a bootstrap method which corrects the inherent dependence among Decision Making Units' efficiency scores. The results indicate that gross domestic product (GDP) per capita and education are significant factors influencing ICT efficiency in curbing corruption while press freedom is not a significant factor. The findings suggest that using ICT to fight corruption in Africa should be implemented parallel with strategies that improve GDP and education if ICT has to successfully reduce corruption.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126187263","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 information displayed on indoor signs and notice boards is of no use to them. In order to assist them with this challenge, we propose a real time system that can recognise a selection of indoor navigational signs placed over clear backgrounds. The selection of signs will consist of common samples from several different types of indoor signs. Given a captured image, the approach is to use image processing techniques to find the region of interest(ROI) that contains the sign and then extract this region for classification. Using sliding windows for searching the ROI can be time consuming and can lead to many false classifications, hence we used a more explicit approach that is faster and more reliable. We first segment the signs by colour, and then by shape recognition. The sign-type classification is done using a tree search structure that enables the use of iterative contour descriptors like the speeded-up-robust-features(SURF). Once a sign has been detected, this information is communicated to the user via stereo headsets. To evaluate the system's performance, several random pictures with and without signs were used to determine the system's detection rate. The user-feedback performance was evaluated by testing the system's usability score with volunteers.","PeriodicalId":269578,"journal":{"name":"Research Conference of the South African Institute of Computer Scientists and Information Technologists","volume":"37 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132738063","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}
