Determining the role of e-government in providing the kind of services that are especially needed has become particularly rele- vant during COVID-19. This paper aims to assess the progress and current state of research on the role of e-government during or in the aftermath of catastrophic events. The purpose of this research is twofold: one, to benefit scholars by providing directions and a basis for further research, and two, to offer guidance to decision-makers involved with disaster management. Design/methodology/approach – The methodology used in this study is a systematic literature review. Multiple databases, including EBSCO, Elsevier, Emerald, JSTOR, Google Scholar, SAGE, ScienceDirect, Scopus, Springer, Taylor and Francis, and Wiley Online Library were searched for ap...

Data envelopment analysis (DEA) is used to construct the Malmquist index (MI) for the growth in productivity, which is then decomposed into two components, change in efficiency (EC) and change in technology (TC). Results from structural equation modeling (SEM) indicate that while all 18 TEs exhibit relationships between investments in telecoms and the TC component, only a subset of the TEs shows a relationship between telecom investments and the EC component.

As object oriented programming languages are becoming more and more widely used, metrics specifically designed for object oriented software are required. In recent years there has been an explosion of new, object oriented software metrics proposed in the literature. Unfortunately, many or most of these proposed metrics have not been validated to measure what they claim to measure. In fact, an analysis of many of these metrics shows that they do not satisfy basic properties of measurement theory, and thus their application has to be suspect. In this paper ten improved metrics are proposed and validated. 1 Introduction In the early days of computer applications, software development was best described as art, rather than science. The absence of design guidelines often resulted in spaghetti code that was unintelligible to those charged with maintaining t...

The objective of this paper is to direct attention to this apparent gap and provide an overview of the issues related to information systems (IS) and IT specifically in developing and emerging economies. Business and social conditions specific to developing and emerging economies and their potential effects on IS/IT implementations are discussed. After a brief review of papers presented at previous AMCIS conferences, some research areas that seem particularly in need of more attention are identified.

Since society has become highly dependent on effective and efficient information systems (IS), understanding how outbreaks may impact IS is critical. By looking at existing literature, problems associated with sustaining reliable IS services, as well as changing needs for IS caused by the new circumstances are explored, and new opportunities for IS after the outbreak are discussed.

Common understanding has been that extensive user involvement is not only important, but absolutely essential to system success. However, earlier studies trying to link user involvement to system success have shown mixed results. In this paper we review 28 empirical research studies that investigate the significance of user involvement. From our results we conclude that user involvement in the systems development process is indeed important to system success. We further identify several key points pertinent to making user involvement effective.

Software development project failures using conventional SDLC are often attributed to project delays, resulting in budget overruns. On the other hand, a well

For example, a business generally produces not a single product, but a portfolio of products, and a project is tackled not by a single individual, but by a team of individuals. Unfortunately, the portfolio selection problem has been largely neglected in the literature. Though many specific problem environments have been discussed using heuristic, ad hoc methods, no general methodology or theory has been developed. This paper proposes an object-oriented framework to provide a theoretical foundation for future research on the portfolio selection problem.

In this paper, based on the published literature, a framework is developed that shows the key factors that affect decision outcomes and data quality management in organizations. These factors are differentiated according to their specific impacts: data quality information and process metadata enhance the awareness in the decision maker about the data used in decisionmaking; TDQM (total data quality management), management experience, and commitment are important factors for overseeing the data; and visualization mitigates information overload for the decision maker.

As the IT workforce is becoming increasingly global and diverse, graduate education must respond. To maintain relevance within this changing environment and to meet new market demands, master’s programs in information systems, geared especially towards working professionals, are becoming more evident. New integrated formats for learning, with a focus on IT leadership and management, have been emerging in the past ten years. However, the IS/IT education research and literature seem to not have caught on to this new trend yet.

Rather than being restricted to ancillary (clerical and accounting-related) activities, they are increasingly relied on to support mainline operational functions. This is most evident among those firms now undertaking transitions from traditionally disaggregated (function-unit specific) MIS-type structures to fully-integrated information system architectures (i.e., Enterprise-Wide Management Support Systems. This suggests the need for a corresponding transition from disaggregated to integrated information system security structures. It is the procedural and mechanical provisions that underlie this complementary transition that are the primary focus of this dissertation. As things now stand, what appears to be the best guide, albeit a bit indirectly, as to what an integrated information system security structure might look like is the ...

As object oriented programming languages have become more widely used, metrics designed specifically for object-oriented software are required. Recently a large number of new metrics for object- oriented software has appeared in the literature. Unfortunately, many of these proposed metrics have not been validated to measure what they purport to measure. In this paper fifty (50) of these metrics are analyzed.

Common understanding has been that extensive user participation is not only important, but absolutely essential to system success. However, earlier studies trying to link user participation to system success have shown mixed results. In this paper, we analyze fourteen more recently published, empirical research studies that investigate the significance of user participation. From our results we conclude that user participation in the systems development process is indeed critical to system success. Common themes are identified.

A first step toward a better comprehension of software measurement is the categorization of software measures by some meaningful taxonomy. The most worthwhile taxonomy would capture the fundamental nature of the object-oriented (O-O) space. The principal characteristics of object-oriented software offer a starting point for such a categorization of measures. This paper introduces a taxonomy of measures based upon fourteen characteristics of object-oriented software gathered from the literature. This taxonomy allows us to easily see gaps or redundancies in the existing O-O measures. The taxonomy also clearly differentiates among taxa so that there is no ambiguity as to the taxon to which a measure belongs. The taxonomy has been populated with measures taken from the literature.

Thus, it is essential that those charged with IT governance pay particular attention to which users may initiate, authorize, process, store, and report transactions. Periodic user access attestations, authorizing appropriate employee use of IT artifacts, are a means of ensuring that proper controls are maintained. Cost-efficient applications to support managing appropriate IT user access are needed to ensure regulatory compliance. This research maps the COBIT 5 framework to the systems development lifecycle (SDLC) to develop a user access attestation system using widely available in-house tools.
