Although, Information and Communication Technology (ICT) practitioners is not capable mitigate the identified risk systematically due to the high magnitude of loss caused by operational, technical and strategic risk. The ICT practitioners need to improve their ability to identify and mitigate the risks to ICT infrastructures. Besides that ICT practitioners in organization find it difficult to mitigate risks if they don’t utilize completely their knowledge. There is need for ICT practitioner to codify knowledge, especially through the development of policies and practices to guide decision makers in mitigate risk in their organizations. The aim of this paper is to develop a process model for capturing, storing, disseminating and utilizing risk knowledge of knowledge-based supporting ICT practitioners to make decisions.

However, the integration of prosumers in the smart grid to facilitate bidirectional flows of energy and information depends on intelligent operations of energy systems and flexible structures of the existing energy markets. But existing energy trading mechanisms are faced with issues of trust, privacy, security, and energy pricing determination. Also, there are fewer studies based on a citizen-centric prosumer approach. Thus, there is need to provide reliable solutions that addresses the aforementioned challenges faced by prosumers in LEC. Advancements in disruptive technologies, such as Distributed Ledger Technologies (DLT), Artificial Intelligence (AI), and the Internet of Things (IoT) have transformed a broad spectrum of intelligent systems in smart cities. Therefore, this study examines the integration of AI and IoT as AIoT and DLT towards a citizen-centric prosumer approach for decentralized energy markets trading. Additionally, this article develops an architectural model for energy prosumption in LEC using design science approach based on a user-centred design method that shows a possible implementation concept to support energy sharing and trading in LEC. The architectural model supports trust, data privacy, security, and energy pricing determination using AI and smart contracts to provides real-time energy trading monitoring, easy access, control, and immutable logs to unearth underlying energy demand and supply patterns thereby supporting citizen-centric prosumer approach. Finally, a use case scenario of DLT and AIoT for prosumption operations is presented.

ICV offers promising tool to address the increasing mobility accessibility challenge faced by older people. Yet, irrespective of the increased ageing population, studies that employed ICV to improve the mobility, walkability, and wayfinding of older people are scarce. This is because the development of ICV in the mobility domain presents several designs, technical, and linguistic challenges. A systematic literature review was adopted grounded on secondary data from the literature and descriptive analysis was employed. Grounded on user-centred design perspective based on the "ability-based design framework" and "ISO 9241-110 framework for ergonomics of human-system interaction." Therefore, this study describes the requirement specifications needed to design an ICV suitable for supporting the mobility behavior of older people. Findings from this paper identifies the perceived factors that influences the use of ICV by older people. Additionally, findings from this study discusses how ICV that simulates human-like behavior can provide personalized mobility, walkability, and wayfinding guide when older people walk in cities. This study provides recommendations for the implementation of a user-centred ICV for safe, independent, accessible mobility for older people in urban environment.

But, irrespective of the mobility and walkability challenges faced by the aging population, studies that employed Artificial Intelligence (AI)-based voice-assistants to reduce risks faced by older people when they use public transportation and walk in built environment are scarce. This is because the development of AI-based voice-assistants suitable for the mobility domain presents several techno–social challenges. Accordingly, this study aims to identify user-centered service design and functional requirements, techno–social factors, and further design an architectural model for an AI-based voice-assistants that provide personalized recommendation to reduce falls, injuries, and accidents faced by older people. Accordingly, a scoping review of the literature grounded on secondary data from 59 studies was conducted and descriptive analysis of the literature and content-related analysis of the literature was carried out. Findings from this study presents the perceived techno-socio factors that may influences older people use of AI-based voice-assistants. More importantly, this study presents user-centred service design and functional requirements needed to be considered in developing voice assistants suitable for older people. Implications from this study provides AI techniques for implementing voice-assistants that provide safe mobility, walkability, and wayfinding for older people in urban areas

In addition, a case study approach was adopted to verify the proposed framework based on data collected from open-ended interviews and sustainability report documents from two government-based institutions in Malaysia. Furthermore, the collected data were analyzed based on content analysis using descriptive and narrative method to present the findings of Green IT components adopted in the selected case studies.FindingsFindings show that sustainability considerations are increasingly being deliberated in institutions. Moreover, finding from the analyzed data also indicates that there is an increased interest towards implementation of Green IT initiatives for developing, operating and usage by practitioners and staff within government-based institutions.Research limitations/implicationsFindings from this study suggest that the Green policy framework components have implications to support only government-based institutions address environmental, social and economic-related issues.Practical implicationsThe developed Green IT components serve as robust indicators or constructs to measure management of Green IT initiatives currently being implemented and thereby provide a framework for sustainability committee members to benchmark their current Green IT practice.Social implicationsThis study provides an agenda to guide government-based institutions achieve sustainability goals. Accordingly, government-based institutions can adopt the framework’s components to evaluate their progress, hence improving their target of attaining sustainability. Besides, this research provides an approach for assessing current practices adopted in government-based institutions against the Green IT components.Originality/valueThe originality of this study is attributed to the fact that this study presents Green IT policy framework to be considered by government-based institutions in achieving sustainability. The framework provides an agenda to simultaneously consider all three dimensions of sustainability the people, planet and profit (social, environment and economic).

These risks should be identified, measured and mitigated. Risk mitigation gives an opportunity to IT practitioners and management to compute risks and develop suitable strategies to treat the risk.Risk mitigation in organizations provides a disciplinary environment for decision making to measure and treat potential risk continuously. Existing model and frameworks provides inadequate support to practitioners in making risk decision pertaining risk mitigation. This is due to the fact that existing models or frameworks lacks the capabilities to support practitioners. In order to address this challenge, this research identifies the processes and components of risk mitigation in organization’s and proposes a framework of risk decision for mitigating both technical and operational risk using software agents and knowledge mapping as techniques.

Presently ICT is seen as an enabler to resolve high energy, cost issues and bring greater efficiency. This is referred as Green ICT which involves energy conservation and cost reduction of ICT usage. Various countries have already applied Green ICT initiatives to reduce CO2 emissions. Greening ICT strategies in enterprise can decrease these negative impacts. Thus Green ICT aimed at influencing not only technology but also competitive strategy and even the legitimacy of some business strategic options in enterprise. Current findings suggest that although ICT Professionals are already concerns about climate change and power consumption of ICT, there is still a lack of a model that can reduce the time taken to implement Green strategies in enhancing business value in enterprise. Therefore this paper utilized secondary research by reviewing literature on Green ICT and developed a Green ICT model fo...
