Making Use of Scenarios for Achieving Effective Use in Community Computing Contexts

The concept of effective use is gaining currency as a way of thinking about usability in community informatics. Broadly defined, effective use is the opportunity and capacity of a community group to leverage information communications technologies (ICTs) in order to achieve their goals. Although effective use is a worthy goal, a process for achieving effective use is not clearly defined. This paper combines the concept of scenarios from human-computer interaction (HCI) and participatory design (PD) in order to identify a design process to enhance participation and technological decision making in community information systems design projects. Our process for achieving effective use focuses first on the efficacy of scenarios as a tool to encourage and support participatory design, and second as an anchoring and adjustment heuristic. This study concludes with future research on effective use in community informatics

Shifting towards community-building in opening up FabLabs for non-expert users

In the early days of Fablabs and other digital fabrication spaces (e.g. hackerspaces, makerspaces), these community spaces that offer public, shared access to high-end manufacturing equipment (e.g. 3D-printers, laser cutters) were often described as having the democratizing potential to empower everyone as future makers. However, research showed that non-expert users are often impeded to engage in such spaces due to various challenges (among other things, the unfamiliarity of available tools and machines, a lack of skills and experience). By describing a case study in which we elucidate different strategies that were used to engage non-expert users in FabLab [anonymized], this paper focuses on the mediating role of the design researchers who be

The Role of Feedback: Metalinguistic and Elicitation on Pronunciation Achievement of Iranian Intermediate EFL Learners

The main goal of this thesis is to investigate the extent to which metalinguistic information and elicitation feedback affect Iranian EFL students to improve their pronunciation achievement. Participants are Iranian students with Intermediate level of proficiency. KET (Key English Test) test was conducted to acknowledge their level of proficiency. Quantitative research was used for the purpose of this study. This study had Meta-linguistic and Elicitation group for six months. Pre-test Post-test design was conducted in order to statistically compare means of both Meta-linguistic and Elicitation groups before and after treatment. The result of data analysis showed that there is a significant difference between means of Meta-linguistic and Elicitation groups. It was concluded that getting metalinguistic information feedback in Meta-linguistic group as a treatment effects on student’s pronunciation achievement but getting elicitation feedback in Elicitation group does not have a significant effect on student’s pronunciation achievement. Keywords: Metalinguistic- Elicitation- Pronunciatio

AMCIS 2002 Panels and Workshops I: Human-Computer Interaction Research in the MIS Discipline

Human Computer Interaction (HCI)or Human Factors studies in MIS are concerned with the ways humans interact with information, technologies, and tasks, especially in business, managerial, organizational, and cultural contexts. This article describes the existence and importance of HCI research in the MIS discipline, its historical development, some of its characteristics, publication opportunities, and future research directions. It is believed that HCI is the subject of a strong research stream in MIS, and will continue to be strong in the foreseeable future. It is hoped that HCI studies can provide the evolution of the human centered technology development that enhances our work/job, our various needs, our organizations, our societies, and ourselves

The fidelity of prototype and testing environment in usability tests

This doctoral thesis investigated what setup of a usability test can best support valid test outcomes. Several aspects of contextual fidelity were manipulated in experimental usability studies, to examine their impact on test results. The first study demonstrated that the medium of prototype presentation has effects on test outcomes, which have not been found in previous research. Using a more hypothesis-driven approach, it was shown that participants exhibited more reading activity when using a paper-based as compared to a computer prototype presented on screen. This resulted in better performance, if task success required reading a short paragraph of text. Consequently, the medium of prototype presentation needs to be considered to avoid that respective usability problems go undetected. A second study demonstrated that additional observers may cause stress for test participants, which can be measured at the physiological level. Some performance indicators were affected, but only in interaction with perceived developmental stage of the test system. A third study investigated the effects of a work or leisure context on the outcome of a usability test. No effects were found for the type of usage context, but even short response time delays proved to be relevant for performance and emotions. Relevant factors for the validity of usability test outcomes were identified and theoretical and practical implications are discussed. Keywords: Usability test; paper prototype; fidelity; observer presence; work and leisure domain; system response time; heart rate variability; validity

Facebook usage in political communication in Ghana: the case of two political parties.

Doctoral Degree. University of KwaZulu-Natal, Durban.The emergence and spread of social media are changing activities in many walks of life. These technologies have ushered in a digital era that has transformed communication, engagements and relationships. Social media have revolutionised how political communication and politics, particularly electoral processes are also done. This study is centred in Ghana and investigated how Facebook is used in intra-party elections by New Patriotic Party and National Democratic Congress. Since the New Patriotic Party took over the reign of political power in 2017, there has been a considerable rise in political vigilantism in Ghana, which some have attributed to lack of direct access to parties and officials due to limited time given to stakeholders during “phone-in” segments on political programmes in traditional media. There are also debates as to whether social media have improved political communication and participation in Africa. More so, studies conducted on political use of social media in Ghana have not explored their appropriation in intra-party elections. The purpose of this study is to shed new light on the debate regarding social media usage in political communication in Africa, examining how Facebook is appropriated by political parties in Ghana. The study employed qualitative and quantitative techniques (mixed methods approach) in sequential triangulation of interviews and content analysis. Underpinned by interpretative and pragmatic paradigms, this study conducted interviews with communication officials of New Patriotic Party and National Democratic Congress. Contents of Facebook posts of the parties were analysed to corroborate or dispute data collected from interviews. Observations were also made from visits and activities of parties during data collection. The transcribed data was thematically organised for the study to analyse and present in narrative forms. Data from content analysis of Facebook was also coded and put into figures, numbers and tabular formats. This study anchored on the theories of technology appropriation, relationship management, and agenda setting. Generally, this study indicated that political parties in Ghana particularly New Patriotic Party and National Democratic Congress use social media especially Facebook in political communication and intra-party elections. However, the parties were particularly using Facebook for public information purposes instead of establishing mutually beneficial relationships through interactive engagements and two-way symmetrical communication on the social networking site, or perhaps not making good use of Facebook especially in internal elections. Parties considered and delivered social media communication on ad-hoc value without concerted efforts and political public relations strategies to maximise potentials. Inasmuch as political parties in Ghana demonstrated the desire to establish relationships by creating pages on vii Facebook to get closer to stakeholders and the public, they could not achieve this. They have focused their attention on passive traditional communication without reconsidering their activities to improve social media use especially “Facebooking” for interactions and mutually beneficial engagements and relationships. This study suggests that political parties improve interactions and conversations with stakeholders. Parties need to create political public relations units of communication professionals with expertise and skills to advice and manage social media engagements as specialised activities to extend mutually beneficial relationships. Communication officials of parties have to be trained in political public relations and social media for more knowledge and understanding of the opportunities and challenges associated with these new forms of communication technologies to harness their utility
