Although Affordance Theory has become increasingly influential in the Information Systems (IS) literature, the exact process through which the affordances of IT are actualised is less studied. In ...this paper, we build on a realist ontology of affordance and an interpretive epistemology of how affordances are perceived and actualised to trace the process of actualisation. On the basis of insights drawn from a case study of a telemedicine project in a remote mountainous region of Nepal, we develop a concept, which we call the “Trajectory of Affordances.” Trajectory of Affordances captures the complex relations between affordances of IT and the role of goal‐oriented actors who perceive and then play a vital role in actualising them, using capabilities that are enabled by facilitating conditions to take the necessary action. Trajectory of Affordances shows that the affordances of IT can travel from perception to actualisation through multiple paths, sometimes clustering together, and in the process, often lead to the emergence of new affordances.
The concept of affordances has become central in information systems literature. However, existing perspectives fall short in providing details on the relational aspect of affordances, which can ...influence actors' perception of them. To increase granularity and specificity in this regard, researchers have suggested that it be supplemented with other concepts or theories. In this article, we argue that the Heideggerian concepts of ‘familiarity’ and ‘referential totality’ are well suited for increasing our understanding of the relational aspects of affordances in information systems research. To explore this idea, we conducted a case study of a project concerning the development of a digital twin (i.e., digital representation of a physical asset) in the Norwegian grid sector. We found that users' familiarity with the digital twin totality enabled them to perceive digital twin affordances, and that without this familiarity, affordances remained latent for the users. Through our study, we offer a nuanced perspective on the relational aspect of affordance perception, contributing to affordance theory in that regard. Further, we contribute to practice and information systems research by providing valuable insights into how digital twins are understood and applied in practice.
In this paper, we explore how the combination of Information and Communication Technologies (ICT) and self‐organised study circles improves rural communities' ability to enhance their economic ...opportunities. We present the case study of an adult study‐circle project in the Kwale County of Kenya with the objective of providing rural communities with viable and sustainable livelihoods. Study circles can be seen as a democratic and emancipatory method for learning, where community groups regularly meet for participatory discussions to educate themselves on a variety of topics of their own interest. The main goal of the study‐circle members was to increase economic opportunities using ICT and, more specifically, to start micro‐businesses, improve production efficacy and methods, and obtain employment. Using the capability approach and affordances as theoretical lenses, our analysis of the explorative case study shows that the outcomes of the study circle were dependent on various conversion factors and facilitating conditions, such as resources, skills, socio‐cultural norms, and infrastructure. The main contributions from our work are represented by the five practical lessons learned from the study‐circle members' goals (starting micro‐businesses, product efficiency, and obtaining employment) from the self‐organised training approach (study circles) and from our theoretical approach (combining the capability approach and affordances).
The objective of this paper is to detect speech forgery using digital audio watermarking and pattern recovery techniques. A digital watermark pattern has been attached with the speech signal to ...detect three kinds of alterations or forgeries such as substitution, insertion, and removal. The watermark pattern will be modified if some changes have been made to the speech contents. Modification and forgery can be measured and detected by pattern recovery. The proposed method uses the cyclic pattern embedding to overcome synchronizing problems of previous detection techniques. In addition, pattern recovery enhances the robustness to compression. This method has been tested and verified using six recording devices, which was used for collecting verbal data. The speech signals were sampled at the rate of 8
kHz and digitized at 16
bits resolution. Randomly chosen regions were substituted, removed, and compressed in MP3 at the rate of 16
kbps as well as in CELP at the rate of 11.5
kbps. The experiment shows the perfect detection for three kinds of forgeries and it proved the validity of the proposed method.
Questions such as ‘What is ICT?’ and ‘What is development?’ are relatively well‐answered and well‐documented in literature but work connecting the two has been limited. Existing ICT4D studies tend to ...be descriptive or prescriptive in nature, and hence the explanation of how and why ICT works in the contexts of developing countries needs further investigation. ICT cannot by itself lead to development: it has to be deployed by actors in a given social, political, cultural, and technical context, under conditions at the time of deployment. The interplay of the above‐mentioned elements in any given development situation relies on underlying mechanisms that may explain how and why ICT leads to development. Therefore, it is important to investigate questions like “What mechanisms link ICT and development?” and “How do we identify these mechanisms?”. To research and answer these questions, we propose a critical realism‐based four‐step methodological approach. The core idea of the critical realism‐based approach suggested in this study is to identify the underlying mechanism (s), particularly in ICT4D contexts, to explain how and why ICT leads to development. We illustrate the proposed methodology by applying it in a case study from Nepal.
Abstract Although Affordance Theory has become increasingly influential in the Information Systems (IS) literature, the exact process through which the affordances of IT are actualised is less ...studied. In this paper, we build on a realist ontology of affordance and an interpretive epistemology of how affordances are perceived and actualised to trace the process of actualisation. On the basis of insights drawn from a case study of a telemedicine project in a remote mountainous region of Nepal, we develop a concept, which we call the “Trajectory of Affordances.” Trajectory of Affordances captures the complex relations between affordances of IT and the role of goal‐oriented actors who perceive and then play a vital role in actualising them, using capabilities that are enabled by facilitating conditions to take the necessary action. Trajectory of Affordances shows that the affordances of IT can travel from perception to actualisation through multiple paths, sometimes clustering together, and in the process, often lead to the emergence of new affordances.
The role of ICT actors in the formation and extension of ICT4D projects is important. The actors through their extended network and aligned interest can enhance the effectiveness of the project which ...in turn enables socioeconomic development opportunities. However, few studies have been conducted to understand the role of these central players. The objective of this paper, therefore, is to address this knowledge gap by conducting a qualitative case study in the Myagdi district in the mountain region of Nepal. In this study we explored the Nepal Wireless Networking Project (NWNP) and examined how an activist started it from one mountain village and gradually extended across more than 150 villages. The formation and extension of information and communication technology for development (ICT4D) projects goes through different phases of identification of relevant ICT actors, roles, negotiations, and their interest alignment. To understand the various phases, we employed Actor‐Network Theory (ANT) and explored how a social activist, in the midst of challenges, initiates the wireless project to facilitate educational and healthcare services to the mountain regions. In continuum, the study found how the activist identified relevant actors and enrolled them to form a network of aligned interest. The study also identified several challenges such as high illiteracy rate, over dependency on focal actor, and poor physical infrastructure that may impede the network building process. Furthermore, we identify some implications for research and practice based on insights from the case study.
While many theories have guided research Information and Communication Technologies for Development (ICT4D), we are yet to construct a clear and coherent narrative that would help us answer the ...question of how ICT fosters development in underdeveloped communities. In this paper, we argue that one of the main reasons for this is that our holistic understanding of ICT4D is seldom grounded in theories to understand the core areas that define the field, namely, ICT, Development, and, '4' which are the transformative processes that link the two. Through a brief literature review, we list theories that have informed ICT4D research in each of these areas. We present examples of theories, namely, Capability Approach, Affordances, and Actor-Network Theory together with Social Capital and illustrate how we have used them in our research. Building on this holistic perspective on theoretical foundation, we propose five agendas for ICT4D research.
