Cloud computing, which refers to an emerging computing model where machines in large data centers can be used to deliver services in a scalable manner, has become popular for corporations in need of inexpensive, large scale computing. Recently, the United States government has begun to utilize cloud computing architectures, platforms, and applications to deliver services and meet the needs of their constituents. Surrounding the use of cloud computing are many risks that can have major impacts on the information and services supported by this technology. This paper discusses the current use of cloud computing in government, and the risks–tangible and intangible–associated with its use. Examining specific cases of government cloud computing, this paper explores the level of understanding of the risks by the departments and agencies that implement this technology. This paper argues that a defined risk management program focused on cloud computing is an essential part of the government IT environment. 相似文献

This study examines the acceptance of cloud computing services in government agencies by focusing on the key characteristics that affect behavioral intent. The study expanded upon the technology acceptance model by incorporating contextual factors such as availability, access, security, and reliability. The research model was empirically verified by investigating the perception of users working in public institutions. Modeling results showed that user intentions and behaviors were largely influenced by the perceived features of cloud services. Also these features were found to be the significant antecedents of cloud computing usefulness and ease of use. The findings should guide governments' promotion of cloud public services to increase user awareness by enhancing usability and appeal and ensuring security. 相似文献

This study examines the adoption of centralized customer service systems in local governments in the United States. Survey data is used to show the relationship between different factors of E-Government adoption and the implementation of this information technology (IT). The results of this study show that the adoption of a centralized customer service system was related to the form of government that the local government had and being located in a central city. The results also indicated that the sophistication of the local government's website was related to the adoption of a centralized customer service system. The results of this study did not support the claim that larger cities are more likely to be adopters of this type of IT. Other results indicate that only 15% of local governments have adopted this IT. These information systems are well-integrated with existing online communication methods such as email and the internet. The information from this IT is commonly used by local governments for performance management and budget development. 相似文献

The effects of e-Government cloud assimilation on public value creation: An empirical study of China
《Government Information Quarterly》2019,36(4):101397
Cloud computing applications have entered the stage of popularization and wide adoption as part of e-Government. Improving the implementation and assimilation of e-Government cloud applications (e-Gov cloud) to create public value has become an important issue. Based on theories of information technology (IT) assimilation, IT value, and organizational ambidexterity, this study develops a model of e-Gov cloud assimilation and explores the individual and joint effects of the depth and breadth dimensions of e-Gov cloud assimilation on public value. The model was tested with partial least squares structural equation modeling (PLS-SEM) using a survey of local government agencies in China. The empirical results show that the two dimensions of e-Gov cloud assimilation - depth and breadth - have significantly positive effects: (1) directly on operational public value and (2) indirectly on strategic public value through operational public value. Moreover, the complementary fit strategy of the depth and breadth of e-Gov cloud has a significantly positive effect on strategic public value, while the balanced fit strategy has no significant effect. These findings contribute to both academic research and practical implications, advancing our understandings of e-Government cloud assimilation on public value creation. 相似文献

Information technology (IT) applications in local government have been mostly used to advance the technical capacity of localities in delivering public services. As decision making responsibility moves from the U.S. federal government to local governments, academic researchers should address the need for developing intuitive decision support systems (DSS) for government managers and senior decision makers. The task-specific models of Web-based information systems (IS) discussed in this study can help local government managers capture information in multimedia format and facilitate information sharing between their department and other agencies without dependency on specific platforms, time differences, or locations in a cost-effective manner. Consequently, research should be encouraged to develop methods that respond to questions of training in the new IS environment and to provide solutions to facilitate service and system integration despite the environmental and political complexity surrounding local governments. 相似文献

Around the world, governments turn to information technology (IT) training programs to enhance equitable delivery of online public services to citizens. However, the effectiveness of these citizen training programs has gone unexplored. This study is motivated by two objectives: 1) To evaluate whether citizen participation in government training programs is associated with greater e-government use among participants, and 2) To assess whether the strength of this relationship varies according to whether a citizen is elderly, disabled, or not – those who are elderly or disabled tend to use e-government the least. We use data from South Korean to examine these objectives. Findings indicate citizen participation in government IT training programs is positively associated with e-government use and that this relationship is stronger for citizens who are elderly or disabled. These findings highlight the potential of government IT training programs to mitigate the digital divide. Implications for research and practice are discussed. 相似文献

The U.S. Government's role as overseer of the World War II airwaves was significant, given the government's task of establishing a supervisory mechanism for the radio industry that would serve the need of national security and, at the same time, minimize the need for bureaucratic intrusion into program decision making. A mechanism also was needed to police the domestic airwaves for unlicensed intruders and to monitor the international airwaves for enemy propaganda. To accomplish these tasks, the government enlisted the services of three agencies: the Federal Communications Commission, the Defense Communications Board, and the Office of Censorship. This paper examines the structure, operation, and contribution of each. 相似文献

This study examines the potential of application service providers (ASPs) to transform electronic government (e-government) services at the local level. The ASP model helps local governments overcome barriers to offering next wave e-government services such as a shortage of skilled IT staff and limited financial resources. The realization of full potential, however, requires first the adoption of an ASP model. Five conditions that favor the decision to use an ASP are (1) strong top management support, (2) promise of large efficiency gains, (3) enough IT capability on the part of the government unit to identify key piece of technology, (4) less burdensome outsourcing rules and procedures, and (5) a variety of high quality and reliable ASPs from which to choose locally. To ensure the success of an ASP project, local governments need to build in-house IT capability to evaluate an ASP and to develop proper performance measures. Management should focus on serving citizens and businesses and develop the capability to negotiate as well as manage service-level contracts with ASPs. Continual top management support is necessary for dealing with possible initial resistance and ensuring interdepartmental communication and cooperation. 相似文献

How well do governments comply with their own transparency statutes? Alarmingly, answers to this question are in short supply because of patchy comparative data. This study begins to address this gap by analyzing an exhaustive compilation of 265 transparency compliance evaluations (i.e. audits) authored by NGOs, academics, and government oversight authorities across Latin America between 2003 and 2018. Aggregating data on patterns of evaluation and public sector compliance with transparency statutes, we find modest increases in compliance over time, strikingly low compliance with passive transparency compliance (i.e. governmental responses to citizen requests) at the local versus national levels of government, and significantly higher compliance scores when government oversight agencies act as evaluators. Our data also reveal worrying gaps in evaluation efforts. Evaluators tend to focus far more on active transparency (i.e. website-based disclosure) than passive transparency, more on national level governments than subnational governments, and preponderantly on the executive as opposed to legislative or judicial branches of government. Textual analyses show that education is the most evaluated policy theme, with financial policies and social services close behind. In presenting the first large-scale cross-national assessment of transparency compliance, the current study brings to light trends in the effectiveness of transparency regimes and patterns of transparency evaluation across Latin America. 相似文献
