<p>The mobile industry in recent years has been growing at a speedy pace where the use of cell phone is no longer limited to conventional usage like the voice communication, but has enriched the customer experiences with mobile internet services and other value added services. Along with the growing mobile industry, technology behind it is also changing accordingly. However, the user acceptance of technology depends on various factors that lead to either user acceptance or rejection. This study thus aims to identify the major determining factors that influence the user to use the 3G mobile internet and examines the interrelation among the determinants along with effect of the demographic variable limited to Kathmandu Valley users. The conceptual framework of this study is based on the extended version of Davis (1989)’s technology acceptance model using variables social influence, price perception, perceived usefulness, perceived ease of use, attitude to use and behavior intention. The primary survey is conducted using a set of questionnaire, which produced 180 valid responses from the mobile users in Kathmandu Valley. The reliability of the data from questionnaire is verified with factor analysis and Cronbach’s alpha. The result shows that social influence has significant influence on perceived ease of use while it has no significant influence on perceived usefulness. Price perception, on the other hand, influences the perceived usefulness. Similarly, perceived usefulness and perceived ease of use influence the attitude of use, which finally influences the behavioral intention. Along with this, social influence is also found to be the extended factors that can influence the attitude of the users, which in turn affects the behavioral intention. Demographic variables, however in this study, have shown no significant influence on the behavioral intentions. On the whole, the usage of 3G mobile internet service is not seen to be satisfying from the study. The major reasons as surveyed from the users themselves for this lower utilization seems to be higher data costs, presence of cheaper alternatives for internet like Wi-Fi internet, quick drainage of battery and slow mobile internet service provided by the mobile service providers. Thus, for mobile service providers, internet service providers are their direct competitors for 3G mobile internet services. This paper enhances understanding of user acceptance of 3G mobile internet services.</p><p>Journal of Business and Social Sciences Research, Vol. 1, No. 2, pp. 135-152</p>

AbstractRecently, the Internet-of-Things technique is believed to play an important role as the foundation of the coming Artificial Intelligence age for its capability to sense and collect real-time context information of the world, and the concept Artificial Intelligence of Things (AIoT) is developed to summarize this vision. However, in typical centralized architecture, the increasing of device links and massive data will bring huge congestion to the network, so that the latency brought by unstable and time-consuming long-distance network transmission limits its development. The multi-access edge computing (MEC) technique is now regarded as the key tool to solve this problem. By establishing a MEC-based AIoT service system at the edge of the network, the latency can be reduced with the help of corresponding AIoT services deployed on nearby edge servers. However, as the edge servers are resource-constrained and energy-intensive, we should be more careful in deploying the related AIoT services, especially when they can be composed to make complex applications. In this paper, we modeled complex AIoT applications using directed acyclic graphs (DAGs), and investigated the relationship between the AIoT application performance and the energy cost in the MEC-based service system by translating it into a multi-objective optimization problem, namely the CA$$^3$$ 3 D problem — the optimization problem was efficiently solved with the help of heuristic algorithm. Besides, with the actual simple or complex workflow data set like the Alibaba Cloud and the Montage project, we conducted comprehensive experiments to evaluate the results of our approach. The results showed that the proposed approach can effectively obtain balanced solutions, and the factors that may impact the results were also adequately explored.

The Government

The Australian Broadcasting Corporation is in the midst of significant change as a result of budgetary pressures from the government and the challenge of the oncoming digital age. Lack of funding and dwindling resources have forced the ABC to shut down many of its regional services and to outsource many of its formerly in-house productions. However, there do appear some ways in which the ABC might meet, as the rhetoric goes, "the challenge of the digital era". Traditionally, the role of the ABC has included the provision of comprehensive coverage of, and service for, the whole of Australia, including regions that would be economically unfeasible for commercial operations to penetrate. Recently, however, budgetary cuts have eroded this role substantially, with the axing of state based current affairs and the cessation of Radio Triple J's planned expansion into regional Australia. The Internet has provided a potential, if problematic, stop-gap solution, through the launch of the ABC's online news service. Internet based news solutions have few of the production-end overheads of the television service. There are no expensive studio set ups, no presenters, no cameras, just text that can be quickly keyed into the system and formatted for instantaneous, non-linear delivery. I should note at this point that currently, this "delivery" is in the passive sense of the word: users must search out the content and download it onto their machines. In Internet jargon, this is called "pull" technology. New technologies being developed promise to "push" the content automatically and directly to a user's computer. The ABC's implementation, taking advantage of all these benefits, is text-based, comprehensive, updated constantly, and easy to use. Currently, however, delivery of Internet-based content is tied to the existing phone network, and with most Internet service providers based in state capitals, regional Internet access is hindered by the cost of long-distance calls. The potential exists, nonetheless, for the ABC to achieve truly national coverage by methods that bypass existing structures. The planned shift by Australian TV networks to digital transmission has the potential to enable new possibilities for public broadcasting. A digital infrastructure could allow information and programming to be cheaply produced at the local level, then recompiled centrally and redistributed across the country. The convergence of computer and television will enable a greater variety of content to be sent to the home -- and, possibly, sent back out again in an altered form. Such a transformation of the way we experience television may well alter the concept of public broadcasting beyond recognition, if not render it obsolete. However, these possibilities, although reasonable given projected advances in technology, so far largely remain fantasy due to the debate over regulation between the Federal government and the commercial networks. It remains to be seen whether the ABC will be able to take advantage of the new opportunities. Citation reference for this article MLA style: Nick Caldwell.

Internet Service

This study surveyed mobile users in the United States and Korea to determine the key differences between the two countries. Survey questions, developed in two languages, were presented in each country to explore the influences of informativeness, entertainment, interactivity, and availability on mobile user dimensions. The study design methods were based on the revision of a uses and gratifications approach, and a relational model of antecedents and consequences was tested with a structural equation modeling approach. Mobile Internet service uses and gratifications were analyzed cross-nationally in a comparative fashion focusing on the differences in the composition of motives in the two countries. Based on the results of this study, practical implications for marketing strategies in mobile service markets and theoretical implications for cross-country studies are recommended accordingly.
