Selected AbstractsModeling software evolution defects: a time series approachJOURNAL OF SOFTWARE MAINTENANCE AND EVOLUTION: RESEARCH AND PRACTICE, Issue 1 2009Uzma Raja Abstract The Department of Information Systems, Statistics and Management Science, prediction of software defects and defect patterns is and will continue to be a critically important software evolution research topic. This study presents a time series analysis of multi-organizational multi-project defects reported during ongoing software evolution efforts. Using data from monthly defect reports for eight open source software projects over five years, this study builds and tests time series models for each sampled project. The resulting model accounts for the ripple effects of defect detection and correction by modeling the autocorrelation of code defect data. The autoregressive integrated moving average model (0,1,1) was found to hold for all sampled projects and thus provide a basis for both descriptive and predictive software defect analysis that is computationally efficient, comprehensible, and easy to apply. The model may be used to evaluate and compare the reliability of candidate software solutions, and to facilitate planning for software evolution budget and time allocation.

Copyright © 2002 Society of Chemical Industry [source] Martin K. Starr: A Visionary Proponent for System Integration, Modular Production, and Catastrophe AvoidancePRODUCTION AND OPERATIONS MANAGEMENT, Issue 1 2007Sushil Gupta Martin K. Starr facilitated the creation of an identity for production and operations management (POM) as an academic discipline. This paper aims to summarize Starr's substantial contributions to scholarly inquiry on system integration and interfunctional coordination, modular production, and catastrophe avoidance. Even after four decades, we describe how his legacy in these areas continues to define several major drivers of operations and supply chain management research and practice. Starr has influenced several generations of students, professors, and executives with his writings, teaching, and leadership roles in the POM community that include 32 years on the faculty of the Columbia School of Business, 15 years as Editor-in-Chief of Management Science, and presidency of the Production and Operations Management Society. [source] A distance learning approach to teaching management science and statisticsINTERNATIONAL TRANSACTIONS IN OPERATIONAL RESEARCH, Issue 2 2003John Lawrence Although there is no universal approach for offering distance learning courses over the Internet, nonetheless distance learning has emerged as a formidable way to offer instruction for many types of courses. One approach that has been successfully used for teaching introductory statistics and management science/operations research courses in a College of Business is discussed. [source] Realizing the Potential of Real Options: Does Theory Meet Practice?JOURNAL OF APPLIED CORPORATE FINANCE, Issue 2 2005Alexander Triantis The idea of viewing corporate investment opportunities as "real options" has been around for over 25 years. Real options concepts and techniques now routinely appear in academic research in finance and economics, and have begun to influence scholarly work in virtually every business discipline, including strategy, organizations, management science, operations management, information systems, accounting, and marketing. Real options concepts have also made considerable headway in practice. Corporate managers are more likely to recognize options in their strategic planning process, and have become more proactive in designing flexibility into projects and contracts, frequently using real options vocabulary in their discussions. Thanks in part to the spread of real options thinking, today's strategic planners are more likely than their predecessors to recognize the "option" value of actions like the following: , dividing up large projects into a number of stages; , investing in the acquisition or production of information; , introducing "modularity" in manufacturing and design; , developing competing prototypes for new products; and , investing in overseas markets. But if real options has clearly succeeded as a way of thinking, the application of real options valuation methods has been limited to companies in relatively few industries and has thus failed to live up to expectations created in the mid- to late-1990s. Increased corporate acceptance and implementations of real options valuation techniques will require several changes coming together. On the theory side, we need more realistic models that better reflect differences between financial and real options, simple heuristic methods that can be more easily implemented (but that have been carefully benchmarked against more precise models), and better guidance on implementation issues such as the estimation of discount rates for the "optionless" underlying projects. On the practitioner side, we need user-friendly real options software, more senior-level buy-in, more deliberate diffusion of real options knowledge throughout organizations, better alignment of managerial incentives with long-term shareholder value, and better-designed contracts to correct the misalignment of incentives across the value chain. If these challenges can be met, there will continue to be a steady if gradual diffusion of real options analysis throughout organizations over the next few decades, with real options eventually becoming not only a standard part of corporate strategic planning, but also the primary valuation tool for assessing the expected shareholder effect of large capital investment projects. [source] ON SOCIAL NETWORK ANALYSIS IN A SUPPLY CHAIN CONTEXT,JOURNAL OF SUPPLY CHAIN MANAGEMENT, Issue 2 2009STEPHEN P. BORGATTI The network perspective is rapidly becoming a lingua franca across virtually all of the sciences from anthropology to physics. In this paper, we provide supply chain researchers with an overview of social network analysis, covering both specific concepts (such as structural holes or betweenness centrality) and the generic explanatory mechanisms that network theorists often invoke to relate network variables to outcomes of interest. One reason for discussing mechanisms is to facilitate appropriate translation and context-specific modification of concepts rather than blind copying. We have also taken care to apply network concepts to both "hard" types of ties (e.g., materials and money flows) and "soft" types of ties (e.g., friendships and sharing-of-information), as both are crucial (and mutually embedded) in the supply chain context. Another aim of the review is to point to areas in other fields that we think are particularly suitable for supply chain management (SCM) to draw network concepts from, such as sociology, ecology, input,output research and even the study of romantic networks. We believe the portability of many network concepts provides a potential for unifying many fields, and a consequence of this for SCM may be to decrease the distance between SCM and other branches of management science. [source] Superperformance: A new theory for optimizationPERFORMANCE IMPROVEMENT, Issue 5 2008Dave Guerra This article examines a new framework for managing and leading that provides an astonishingly simple path forward through today's complex world of work, introducing a new paradigm for optimizing both organizations and individuals. Superperformance emerges when process and passion merge to become one. The discovery of superperformance points to the incontrovertible need for a new management science. [source] Twenty Years of the Journal of Product Innovation Management: History, Participants, and Knowledge Stock and FlowsTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 3 2007Wim Biemans The Journal of Product Innovation Management (JPIM) serves as a marketplace for science-based, innovative ideas that are produced and consumed by scholars and businesspeople. Now that JPIM has existed for 20 years, two intriguing questions emerge: (1) How has the journal evolved over time in terms of knowledge stock, that is, what are the characteristics of the growing stock of knowledge published by JPIM over the years; and (2) how has the journal evolved in knowledge flow, that is, how is JPIM influenced by other scientific publications and what is its impact on other journals? In terms of knowledge stock, over 35% of the articles published over the 20 years investigate processes and metrics for performance management. The next most frequently published area was strategy, planning, and decision making (20%), followed by customer and market research (17%). The dominant research method used was a cross-sectional large-sample survey, and the focus most usually is at the project level of the firm. The large majority of JPIM authors (60%) have a marketing background, with the remaining 40% representing numerous functional domains. Academics at all levels publish in JPIM, and though most authors hail from North America, the Dutch are a significant second group. JPIM was analyzed from a knowledge-flow perspective by looking at the scientific sources used by JPIM authors to develop their ideas and articles. To this end a bibliometric analysis was performed by analyzing all references in articles published in JPIM. During 1984,2003 JPIM published 488 articles, containing 10,314 references to journals and 6,533 references to other sources. Some 20% of these references (2,020) were self-references to JPIM articles. The remaining 8,294 journal references were to articles in 287 journals in the fields of management (25%), marketing (24%), and management of technology (14%). However, it should be pointed out that many domains were dominated by a limited number of journals. The second component of knowledge flow concerns the extent to which the ideas developed in JPIM are consumed by other authors. Again, bibliometric analysis was used to analyze data from the Social Sciences Citation Index (SSCI) about citations to JPIM in other journals. For the period 1984,2005, the SSCI registered 7,773 citations to JPIM in 2,067 articles published in 278 journals (including the 2,020 self-citations in JPIM). The functional areas most frequently citing JPIM are management of technology (25%), marketing (15%), management (14%), and operations management and management science (9%). Again, several domains were found to be dominated by a limited number of journals. At the level of individual journals the analysis shows a growing impact of JPIM on management of technology journals. The knowledge-flow analysis demonstrates how JPIM functions as a bridge between the knowledge from various domains and the body of knowledge on management of technology. It suggests a growing specialization of the field of technology innovation management, with JPIM being firmly entrenched as the acknowledged leading journal. [source] Identifying impediments to SRI in Europe: a review of the practitioner and academic literatureBUSINESS ETHICS: A EUROPEAN REVIEW, Issue 3 2008Carmen Juravle For more than 15 years, the investment community and the academic community have written extensively on socially responsible investment (SRI). Despite the abundance of SRI thought, the adoption of SRI practices among institutional investors is a comparative rarity. This paper endeavours to achieve two goals. First, by integrating the practitioner and academic literature on the topic, the paper attempts to identify the many impediments to SRI in Europe from an institutional investor's perspective. Second, the paper proposes a unitary framework to conceptually organize the impediments to SRI by using insights from different relevant research perspectives: behavioural finance, organizational behaviour, institutional theory, economic sociology, management science and finance. The paper concludes by presenting the main shortcomings within both the academic and the practitioner literature on SRI and by providing conceptual and methodological recommendations for further research. [source] Is There Conceptual Convergence in Entrepreneurship Research?ENTREPRENEURSHIP THEORY AND PRACTICE, Issue 3 2006A Co-Citation Analysis of Frontiers of Entrepreneurship Research Conceptual convergence is often seen as a holy grail in entrepreneurship research. Yet little empirical research has focused specifically on the extent and nature of this convergence. We address this issue by content-analyzing the networks of co-citation emerging from the 20,184 references listed in the 960 full-length articles published in the Frontiers of Entrepreneurship Research series between 1981 and 2004. Our results provide evidence for the varying levels of convergence that have characterized entrepreneurship research over the years, as well as the evolution of the conceptual themes that have attracted scholars' attention in different periods. In addition, we provide evidence that the field relies increasingly on its own literature, something that points toward the unique contribution that it makes to the management sciences. [source] From Polychronicity to Multitasking: The Warping of Time Across Disciplinary BoundariesANTHROPOLOGY OF WORK REVIEW, Issue 2 2009Amy Todd Abstract Anthropologist Edward T. Hall's contrast between polychronic and monochronic orientations toward time has stimulated research in the business and management sciences. While Hall's approach to time is ethnographic, the business and management sciences measure polychronicity with a survey instrument, the Inventory of Polychronic Values (IPV). An examination of the IPV and the results it has yielded, however, indicate that it is not measuring polychronicity in the ethnographic sense. The IPV remains firmly within monochronic time and thus fails to seriously engage cultural difference. The transformation of the ethnographic meaning of polychronic to a conceptual one raises methodological and analytical questions of general relevance to the cross-cultural study of work.
