The purpose of this paper is to analyze the influence of Technology Providers, Public Administrations and R&D Institutions on Cloud Computing adoption. This research also considers Killer Applications and Success Cases as other environmental factors.

Factorial analyses and structural equation models were used on a sample of high-technology firms located in technological parks in Southern Europe, with more than ten employees and sustained investments in R&D.

Results show that Technology Providers and Success Cases are determinant in Cloud Computing adoption. Moreover, Killer Applications are a forerunner for Success Cases.

An appropriate fit between the tools and resources provided by suppliers and the internal resources of the company is needed to create competitive advantages. Firms should evaluate Technology Providers, identify Success Cases to Cloud Computing adoption and implement technological benchmarking.

This study contributes to Cloud Computing adoption literature because it includes Technology Providers, Public Administrations and R&D Institutions simultaneously as well as other variables as Killer Applications and Success Cases. The importance of the external agents on information technology (IT) adoption, especially when the technologies to be adopted are new and in an emergent stage, together with the lack of prior investigations focusing on specific environmental factors affecting the adoption of these new, emerging IT, justify the value of this research.

This paper aims to develop a model and measurement to investigate the factors influencing cloud computing adoption as a part of developing countries’ alternatives to implement e-government services.

This study proposes a theoretical model based on the literature of technology adoption models. It constructs scale measurements for the proposed model constructs by extracting and adapting the items from the literature. The authors verify the scales’ content validity and reliability by applying face validity, pre-testing and pilot study. For the pilot study, the authors collect the data from 26 information technology staff in five public organizations in Yemen. The authors test the reliability of the scales using Cronbach’s alpha criterion, and then conduct exploratory factor analysis to evaluate the validity of the scales.

The results show that the scale measurements meet the conventional criteria of reliability and validity.

Theoretically, this paper provides an integrated model for examining cloud computing adoption for e-government implementation in developing countries. In addition, it develops an instrument to empirically investigate the influencing factors of cloud computing adoption in the context of developing countries’ e-government initiatives.

Cloud computing originated in central data centers that are connected to the backbone of the Internet. The network transport to and from a distant data center incurs long latencies that hinder modern low-latency applications. In order to flexibly support the computing demands of users, cloud computing is evolving toward a continuum of cloud computing resources that are distributed between the end users and a distant data center. The purpose of this review paper is to concisely summarize the state-of-the-art in the evolving cloud computing field and to outline research imperatives.

The authors identify two main dimensions (or axes) of development of cloud computing: the trend toward flexibility of scaling computing resources, which the authors denote as Flex-Cloud, and the trend toward ubiquitous cloud computing, which the authors denote as Ubi-Cloud. Along these two axes of Flex-Cloud and Ubi-Cloud, the authors review the existing research and development and identify pressing open problems.

The authors find that extensive research and development efforts have addressed some Ubi-Cloud and Flex-Cloud challenges resulting in exciting advances to date. However, a wide array of research challenges remains open, thus providing a fertile field for future research and development.

This review paper is the first to define the concept of the Ubi-Flex-Cloud as the two-dimensional research and design space for cloud computing research and development. The Ubi-Flex-Cloud concept can serve as a foundation and reference framework for planning and positioning future cloud computing research and development efforts.

Switching to public cloud enterprise resource planning (ERP) systems not only provides financial and functional benefits to organizations, but also results in sunk costs of incumbent systems and uncertainty costs of cloud systems. The purpose of this study is to investigate the enablers and inhibitors concerning switching to cloud ERP systems at the organizational level.

Data were collected from 212 top managers and owners of the enterprises in Taiwan, and 10 hypotheses were examined using structural equation modeling.

Technological (system quality), organizational (financial advantage), and environmental contexts (industry pressure) are found to be the antecedents of switching benefits. Perceived risk of cloud ERP systems and satisfaction with and breadth of use of incumbent ERP systems are found to be the predictors of switching costs. Switching benefits positively affect switching intention, but switching costs negatively affect switching intention.

This study develops a theoretical model grounded in a set of theoretical foundations, including two-factor theory, technology-organization-environment (TOE) framework, information systems (IS) success model, and expectation confirmation theory (ECT). Two-factor theory is used to characterize switching benefits and costs that affect switching intention. Technological factors come from IS success model, and the factors affecting benefits are organized based on TOE framework. Sunk costs of incumbent ERP systems are developed based on ECT.

Different from previous studies on cloud computing adoption, this study provides insights into switching intention to cloud computing. The study also proposes an integrated model grounded in multiple perspectives to explain organizations' decisions to switch to cloud ERP systems. These findings help cloud service providers better understand how to promote cloud ERP adoption from technical, organizational, and environmental perspectives.

This study aims to explore the influence of contingent factors on the assimilation of the cloud enterprises resources plan (ERP) system in the UAE’s public sector. It explains the relationship between institutional logics and institutional work while implementing ERP-based cloud computing (CC) to transform the government.

This study uses qualitative methods and an interpretive approach to provide an in-depth explanation for a detailed case study in the public sector. The institutional logics framework has been used to inform the integration between ERP system and CC in the public sector case.

Findings show that the UAE public sector could align institutional work processes with the inbuilt logics of ERP-based CC, resulting in successful assimilation of the cloud version. This study concludes that institutional pressures in highly institutionalized environments will generate organizational responses, but those responses are dependent upon and influenced by aspects of organizational culture. This study found that the organizational culture has led to a radical change by implementing the cloud ERP system and institutionalizing its usage toward transforming government. Moreover, ERP assimilation is the extent to which an organization has developed from understanding the ERP system’s functionalities to mastering and deploying them in their processes.

This study has important implications and contributions to the literature in three ways. First, this study examines an understudied topic, the interaction between CC and institutional logics. Second, this study contributes to the public sector research by providing a fine-tuned interpretation of the organization’s strategic behavior in response to a new information technology (IT) trend. Finally, this study also focuses on this new trend of CC which can influence the global IT industry, and it is worthy of being considered.

Explanatory case study research has a value to the public sector that one might be discovering new phenomena while analyzing the public sector case. The implementation of cloud ERP is one of the best methods of integrating technology with the public sector’s organizational, technical, economic, social, cultural and other environmental domains.

Modern technological solutions are rapidly changing the information landscape in library and information establishments. One such innovative solution that is gaining momentum in information centers is cloud computing. The purpose of this paper is to explore and compare opportunities and challenges of “cloud computing paradigm” in handling and supporting delivery of information services in university libraries in the face of the present hard economic situation and limited financial budgets.

The study is based on current academic literature, document analysis, several editorials and articles on the potential and challenges of cloud computing paradigm in university library and information centers.

Cloud computing is proving as the best management practice of salvaging information services in university libraries due to numerous competing challenges and issues in institutions of higher education. University libraries in developing countries face many challenges of inadequate information infrastructure, limited financial budgets, manpower issues and rapid changes in technological systems. In the context of hard economic times, cloud computing is critical in adding value as well as advancing the goals and objectives of modern university libraries. Cloud computing is the “best technology practice” that is poised to play crucial roles in enhancing quality provision and delivery of information services in university library and information centers. There are many competing challenges and claims, but potential benefits count more.

The study is based on the ideas of cloud services conceptualized from reading academic literature, document analysis, several editorials, articles and professional work experience. The paper identifies that cloud computing paradigm is useful in achieving the goals and objectives of university libraries in this hard economic situation facing institutions of higher learning.

The paper provides practical insights that cloud computing is the “must have technology” for modern university library and information centers already burdened with the demand to develop effective and efficient technological solutions due to subsequent changing needs of the digital information environment. This study is useful for university libraries, information professionals, information communication technology professionals and university management.

Cloud computing paradigm provides university libraries with the business opportunity to use comprehensive technological solutions with reduced capital expenditure and safe methods of data storage. This eases the inconveniences normally caused by the need to develop and own such comprehensive technological solutions.

This research looks at the potential of the emerging trend of “cloud computing paradigm” in enhancing quality provision and delivery of information services in university library and information centers in the context of limited financial budgets. Cloud computing has been gaining momentum in Kenya, especially in business organizations as compared to library and information establishments.

This paper seeks to present a methodology for measuring the outcomes of public access computing as well as presenting and comparing the main results of baseline studies conducted in Lithuania and Latvia.

Both baseline studies use a combination of quantitative and qualitative methods and both include multi‐perspective, longitudinal design and nation‐wide samples.

The benefits that users can gain from using PAC in public libraries include access to ICT, technology training and assistance, expanded employment opportunities, conducting commercial transactions, access to and assistance with local, state and federal government electronic services, and support for learning, communication and personal identity.

Since these are two baseline‐studies, they do not yet offer scope for comparisons over time, although these will be addressed in both countries. The main problem of impact‐focused research is that it is very tightly linked to influences on individuals, so it is difficult to trace changes and improvements back to the library. The paper shows methods that are currently being tested and used.

The paper reports on the baseline stage of systematic impact assessment programmes being conducted in Latvia and Lithuania as part of their public access computing in public libraries development work, supported by their respective governments and part‐funded by the Bill and Melinda Gates Foundation.

Recent spacecraft attitude control systems tend to use wireless communication for cost-saving and distributed mission purposes while encountering limited communication resources and data exposure issues. This paper aims to study the attitude control problem with low communication frequency under the sampled-data.

The authors propose constructive control system structures based on quantization and event-triggered methods for intra-spacecraft and multi-spacecraft systems, and they also provide potential solutions to shield the control system's data security. The proposed control architectures can effectively save communication resources for both intra-spacecraft and multi-spacecraft systems.

The proposed control architectures no longer require sensors with trigger-ing mechanism and can achieve distributed control schemes. This paper also provides proposals of employing the public key encryption to secure the data in control-loop, which is transmitted by the event-triggered control mechanism.

Spacecraft attempts to use wireless communication, yet the attitude control system does not follow up promptly to accommodate these variations. Compared with existing approaches, the proposed control structures can save communication resources of control-loop in multi-sections effectively, and systematically, by rationally configuring the location of quantization and event-triggered mechanisms.

This paper presents several new control schemes and a necessary condition for the employment of encryption algorithms for control systems based on event-based communication.

In recent years it has become common to hear about the virtues and benefits of the so‐called “cloud” for the use of corporate software. Although the use of the cloud in the business environment has already transformed the concept of data storage and resource management, its use in the field of libraries and information centers is somewhat less widespread. This article aims to outline its benefits and drawbacks.

The article describes the features of cloud computing, how it can be used in a professional environment, and its benefits and drawbacks,

Cloud computing is a highly scalable platform promising quick access to hardware and software over the internet, in addition to easy management and access by non‐expert users. It relies on technologies such as virtualization, programming techniques such as multi‐tenancy and/or scalability, load balancing and optimal performance, to ensure that resources are offered quickly and easily.

In the case of public clouds, the techniques generate economies of scale arising from the efficient use of hardware and human resources. These economies of scale, in turn, have an effect on the price the customer pays, which is of great interest to any institution in current times. There are several commercial suppliers already offering various adaptations of their products which make the use of the cloud possible to a lesser or greater extent. However, many of these are not really systems designed by and for cloud computing but rather adjustments of their commercial developments that enable them to continue selling their traditional products.

The article focuses on cloud computing and its use in a professional library environment.

The purpose of this paper is to propose a model to map the on-premise computing system of the university with cloud computing for achieving an effective and reliable university e-governance (e-gov) system.

The proposed model incorporates the university’s internal e-gov system with cloud computing in order to achieve better reliability, accessibility and availability of e-gov services while keeping the recurring expenditure low. This model has been implemented (and tested on a university e-gov system) in the University of Kashmir (UOK); case study of this implementation has been chosen as the research methodology to discuss and demonstrate the proposed model.

According to the results based on practical implementation, the proposed model is ideal for e-governed systems as it provided adequate cost savings and high availability (HA) with operational ease, apart from continuing to have the necessary security in place to maintain confidential information such as student details, grades, etc.

The implication of this study is to achieve HA and to reduce the cost from using external clouds, mapping internal IT servers of the university with the external cloud computing services.

Because no established mapping model for universities has been provided for effective, low-cost, highly available university e-gov system, the proposed mapping model through this paper closes this gap and provides guidelines to implement a hybrid-mapped e-gov model for universities while keeping the recurring expenditure on cloud computing minimal. The paper provides the perceptions of its adoption at UOK for achieving high reliability, accessibility and uptime of its e-gov applications while keeping the recurring expenditure on cloud computing minimal.
