On The Origins Of Advance Fee Fraud Electronic Mails: A Technical Investigation Using Internet Protocol Address Tracers, Olumide Longe, Adenike Osofisan

The African Journal of Information Systems

One issue that is concerning to the web security community is the correct identification of the origins of advance fee fraud mails. This has serious implications for directing concerted efforts towards mitigating the malaise in the right direction. Although previous research (Cuckier et al, 2007, Gbenga, 2007; Igwe, 2007; Progame, 2007) opined that these mails originate mainly from Nigeria and other West African Countries, research is warranted using available tracking tools to validate previously held notions about the issue of advance fee e-fraud mails. We harvested in real-time aggregated advance fraud e-mails over a two year period using the sinkhole …

Confidence Weighted Mean Reversion Strategy For On-Line Portfolio Selection, Bin Li, Steven C. H. Hoi, Peilin Zhao, Vivek Gopalkrishnan

Research Collection School Of Computing and Information Systems

On-line portfolio selection has been attracting increasing attention from the data mining and machine learning communities. All existing on-line portfolio selection strategies focus on the first order information of a portfolio vector, though the second order information may also be beneficial to a strategy. Moreover, empirical evidences show that the stock price relatives may follow the mean reversion property, which has not been fully exploited by existing strategies. This article proposes a novel on-line portfolio selection strategy named ``Confidence Weighted Mean Reversion'' (CWMR). Inspired by the mean reversion principle in finance and confidence weighted online learning technique in machine learning, …

The Effect Of Employee Engagement On Continuance And Normative Commitment To The Organization, Wai Kwan (Elaine) Lau

Management Faculty Research

A positive relationship between employee engagement and affective commitment is already documented in the literature. However, we do not adequately know how engagement is associated with continuance and normative commitment. Using survey methodology we find that while engagement has a non-significant positive association with continuance commitment, it has a positive association with normative commitment. No negative association was found between engagement and continuance commitment. This study’s results support recent critiques to Allen and Meyer’s three-dimensional model of organizational commitment.

How Information Management Capability Influences Firm Performance, Sunil Mithas, Narayan Ramasubbu, V. Sambamurthy

Research Collection School Of Computing and Information Systems

How do information technology capabilities contribute to firm performance? This study develops a conceptual model linking IT-enabled information management capability with three important organizational capabilities (customer management capability, process management capability, and performance management capability). We argue that these three capabilities mediate the relationship between information management capability and firm performance. To test our conceptual model, we use a rare archival data set that contains actual scores from multidimensional and high-quality assessments of firms and intraorganizational units of a conglomerate business group that had adopted a model of performance excellence for organizational transformation based on the Baldrige criteria. This research …

The Effects Of Decision Aid Structural Restrictiveness On Decision-Making Outcomes, Poh Sun Seow

Research Collection School Of Accountancy

Decision aids are often designed to direct decision-makers' attention to potential problems or solutions prompted by the decision aid; but in most instances, it is impossible to prompt all possible issues that should be considered in making a decision. Decision aids can induce decision-making biases whereby users focus only on the issues identified by the decision aid and fail to adequately consider other issues that are not identified by the decision aid. The purpose of this study is to investigate whether restricting how users interact with computerized decision aids affects their performance by limiting their ability to consider other possible …

Accounting Information Systems Research Over The Past Decade: Past And Future Trends, Colin Ferguson, Poh Sun Seow

Research Collection School Of Accountancy

This article reviews the extant accounting information systems (AIS) literature by conducting an analysis of AIS articles published in 18 leading accounting, management information systems, and computer science journals from 1999 to 2009 with a view to identifying whether or not the focus of AIS research has changed, and if so how it has changed, since the Poston and Grabski’s (2000) review of AIS research from 1982 to 1998. We also report our insights into where AIS research is likely to be heading in the future. We analyse each of the 395 articles identified as reporting AIS research to identify …

Making A Science Of Service Systems Practical: Seeking Usefulness And Understandability While Avoiding Unnecessary Assumptions And Restrictions, Steven Alter

Business Analytics and Information Systems

This book’s theme is “The Science of Service Systems,” yet there is substantial question about whether the definition and nature of service systems have been articulated adequately. This paper examines definitions of service and service system that could frame or otherwise influence future developments in service science and could have implications for what should and should not be included within service science. It argues that the initial development of service science should use straightforward definitions that are understandable, useful, broadly applicable, and teachable. It proposes a definition of service system that is different from the definition proposed in this book’s …

Extending A Systems Analysis Method For Business Professionals, Steven Alter

Business Analytics and Information Systems

Despite having been explored, described, theorized, and measured in hundreds of IS research articles, frequent difficulties related to user participation and business/IT communication persist in relation to project management, specification of requirements, implementation in organizations, business/IT alignment, and IS failures. We report on an extension of a long term design sci-ence research project that previously demonstrated a possible path toward ad-dressing these longstanding problems by empowering business professionals to analyze systems in business terms rather than in formalisms for IT specialists. Previous research demonstrated that most of 75 working business professionals with extensive business experience were able to use the …

Using Work System Theory To Achieve Greater Business Value From Erp By Exploring Alternative Design Spaces, Steven Alter

Business Analytics and Information Systems

This paper explains how various aspects of work system theory (WST) can be applied to achieve greater business value from ERP by assuming that the underlying "design spaces" encompass much more than the features, configuration, and limitations of ERP software. It uses WST concepts to identify directions for achieving business value that might not be considered thoroughly in ERP implementations that focus primarily on converting from legacy software to ERP software.

This paper starts by summarizing basic premises concerning the relationship between work systems and ERP. Focusing on the context of ERP usage, it explains the elements of the two …

Effects Of Perceiver / Target Gender And Social Networking Presence On Web-Based Impression Formation, Timothy R. Hill, Leslie J. Albert, Shailaja Venkatsubramanyan

Faculty Publications, Information Systems & Technology

As the Web has expanded in its use and utility it has fundamentally changed the way in which individuals gather and use information. This paper suggests that those changes give rise to tangible and significant effects in the impressions people form of others using Web-based information. This study explores the impacts of perceiver gender, target gender, and social networking presence on subjects’ perceptions of potential teammates otherwise unknown to them as revealed by ratings they assign based only on search engine results. Experiments reveal differences in how male and female perceivers view others’ social networking activity in general and suggest …

How Cios Overcome The Competing Values Challenge: Irish Cios’ Perspectives, Harvey Enns, Dean B. Mcfarlin, Paul B. Sweeney

MIS/OM/DS Faculty Publications

Competing values are a fact of organizational life. However, there are gaps in our understanding about how these opposing beliefs hinder influence processes. This article draws on interview data to demonstrate how Irish Chief Information Officers (CIOs) are able to convince their colleagues to support new projects within their firms in the face of competing values. Focused interviews were used to explore the influence process and the competing values phenomenon, since this type of research is at an early stage and qualitative methods and analysis serve as a rich source of theory development.

The data showed that the CIOs who …

Faculty Publications, Information Systems & Technology

As a case example for the design and implementation of a public decision support site, a variety of free Google tools are applied to supporting deer management decisions. A large number of communities throughout the country are engaged in what is often described as one of the most contentious decisions facing local governments. These decision makers routinely look to the internet for decision support, but information can be contradictory and difficult to find. To determine issues and requirements, data was collected using Google Search, Google keyword data, and a Google Alert was set up to retrieve news and information on …

Reconciling The Social/Human And Technical/Material In Is Research Without Trying Too Hard, Steven Alter

Business Analytics and Information Systems

This contribution to the SIGPHIL workshop on reconciling the social and technical in IS research proposes a sociotechnical approach that addresses many issues related to the long-standing duality of the social/human versus the technical/material. It shows that a sociotechnical approach based on work system concepts 1) highlights and potentially bypasses extremely basic ontological stumbling blocks in IS research, 2) incorporates many of the topics and concerns of the original sociotechnical school, 3) illuminates issues related to the duality of the social/human versus the technical/material, and 4) addresses these topics using concepts and terminology that are much easier to understand than …
