    ABSTRACT The advantages and challenges of cloud computing services adoption by Small and Medium Size Enterprises (SMEs) in the Kumasi Metropolis are examined in this paper. SMEs in Ghana lack adequate information technology skills for record keeping and information management, marketing and processing. It will be beneficial for SMEs in Ghana to use cloud conjugating for enable productivity, dependability, cost savings, and corporate cooperation. Although, the benefits of cloud computing are enormous, due to a number of obstacles, the widespread implementation of cloud computing among SMEs is slow and discouraging. The impact of the use of cloud computing on the performance of the organization has also been thoroughly explored in this study. Using a combination of methods. the study gathered quantitative data using questionnaires. whereas interview guides were used to gather qualitative data. In assessing the effects of the use of cloud computing on the firm\u27s performance, a simple linear regression was used to ascertain the correlation between them. The findings establish that cloud computing has a major influence on business performance. Data were gathered in the Kumasi Metropolitan Area

It provides information to CIOs and CTOs about big data by: (a) identifying business examples, (b) describing the relationship to data-intensive computing, (c) exploring opportunities and limitations, and (d) identifying cost factors

    On the effect of exploiting gpus for a more Eco-sustainable lease of life

    It has been estimated that about 2% of global carbon dioxide emissions can be attributed to IT systems. Green (or sustainable) computing refers to supporting business critical computing needs with the least possible amount of power. This phenomenon changes the priorities in the design of new software systems and in the way companies handle existing ones. In this paper, we present the results of a research project aimed to develop a migration strategy to give an existing software system a new and more eco-sustainable lease of life. We applied a strategy for migrating a subject system that performs intensive and massive computation to a target architecture based on a Graphics Processing Unit (GPU). We validated our solution on a system for path finding robot simulations. An analysis on execution time and energy consumption indicated that: (i) the execution time of the migrated system is less than the execution time of the original system; and (ii) the migrated system reduces energy waste, so suggesting that it is more eco-sustainable than its original version. Our findings improve the body of knowledge on the effect of using the GPU in green computing. © 2015 World Scientific Publishing Company

    The problem researched was small business leaders\u27 early and limited adoption of cloud computing. Business leaders that do not use cloud computing may forfeit the benefits of its lower capital costs and ubiquitous accessibility. Anchored in a diffusion of innovation theory, the purpose of this quantitative cross-sectional survey study was to examine if there is a relationship between small business leaders\u27 view of cloud-computing attributes of compatibility, complexity, observability, relative advantage, results demonstrable, trialability, and voluntariness and intent to use cloud computing. The central research question involved understanding the extent to which each cloud-computing attribute relate to small business leaders\u27 intent to use cloud computing. A sample of 3,897 small business leaders were selected from a commerce authority e-mail list yielding 151 completed surveys that were analyzed using regression. Significant correlations were found for the relationships between the independent variables of compatibility, complexity, observability, relative advantage, and results demonstrable and the dependent variable intent to use cloud computing. However, no significant correlation was found between the independent variable voluntariness and intent to use. The findings might provide new insights relating to cloud-computing deployment and commercialization strategies for small business leaders. Implications for positive social change include the need to prepare for new skills for workers affected by cloud computing adoption and cloud-computing ecosystem\u27s reduced environmental consequences and policies

    Cloud-based technology, which is now well established, helps reducing costs and providing accessibility, reliability and flexibility. However, the Yemen Higher educational system has not yet embraced cloud computing due to security and privacy concerns, lack of trust, negative cultural attitudes (i.e. tribalism), and most importantly, little digital devices experience in educational settings as well as lack of knowledge and technical know-how. Thus, this study proposes a conceptual model of cloud computing (CC) adoption in Yemen HEIs by investigating the influence of Technology, Organization and Environment (TOE) factors. In addition, this study investigates the moderating effect of tribalism culture in the relationships between the identified factors and CC adoption. The study employed both qualitative and quantitative approaches. A preliminary study through semi-structured interviews with ten (10) participants from top management of HEIs to refine and confirm the proposed model. The quantitative approach was used to determine the factors that influence CC adoption in Yemen HEIs through a questionnaire survey. Data were collected from 328 respondents in 38 HEIs and analyzed using Partial Least Square (PLS) Structural Equation Modelling (SEM). The results showed that relative advantage, reliability, compatibility, security, technology readiness, top management support, regulatory policy and competitive pressure have a positive significant impact on CC adoption. However, tribalism culture has a negative significant impact towards CC adoption. The study also found that tribalism culture moderates the relationship between compatibility, reliability, security, relative advantage, regulatory policy and CC adoption. This study contributes to TOE model adoption by including the cultural factor as a moderator towards CC adoption in Yemen HEIs. The study also provides a model and insights for HEIs, technology consultants, vendors and policy makers in better understanding of the factors that influence CC adoption in least developed countries (LDCs), specifically, Yemen

    A framework for enhancing government service delivery using mobile technologies: an African countries context

    Get PDF
    Electronic government (e-government) is how the providers of public services interact with the citizen and business via electronic means. The internet is the most commonly used electronic channel. E-government can provide major benefits to citizens and businesses by making the delivery of public services more efficient and effective. However, recent advances in mobile technology have offered the potential to support government services at various levels. This has made it possible to deliver services to the citizens who have no convenient physical access to government services, for example, people living in rural areas and those who are continually on the move, such as business professionals. This study explores the possibilities of effectiveness, resistance, opportunities and issues related to supporting government services delivery through using mobile cellular technologies. This research study focused on the South African and Nigerian contexts. The focus was to explore various ways that the government can use mobile technologies to improve the provision of government services. A major output of this research work is a conceptual framework to guide mobile government implementation as a vehicle for delivery of government services. Literature from both academic and professional domains were consulted throughout the study. Furthermore, a case study research was conducted in two organisations, which are different in terms of cultural and transformative settings (one in South Africa and another in Nigeria). The study followed an interpretive research approach, and collected data through semi-structured interviews in the two organizations. The data gathered were relevant to the implementation of m-government systems. The study relied on two underpinning theoretical frameworks, namely Structuration Theory and Actor Network Theory to understand the socio-technical factors affecting the implementation of m-government systems in government organisations. The perspective of duality of structure and moments of translation from both Structuration Theory and Actor Network Theory were adopted to analyse the data collected in the case study organisations
