Abstract: This study investigates the relationship between strategic leader language (as embodied in Motivating Language Theory) and employee absenteeism. Structural equation modeling measured two perspectives for the impact of leader spoken language: employee absenteeism attitudes and actual attendance. Results suggest that leader language does in fact have a positive, significant relationship with work attendance. However, no similar effect was reported for employee attitudes towards absenteeism.
Abstract: Markets with a highly diverse customer base provide the context within which we assess firms’ ability to develop absorptive capacity. Within this context, we discuss a conceptual model that shows theory-derived relationships between components of absorptive capacity and various aspects of diversity. Theoretical concepts from the diversity-related literature and elements of resource-based theory, upper echelons theory, and learning theory are used to support propositions derived from the model.

Using information from the matrix, a new customer-oriented IB Major in Business and Economic School programme will be designed.
Abstract: Ethical decision making was investigated in various disciplines. However, with the growing popularity of the Internet, new ethical challenges emerge. A framework was developed for students’ ethical decision making based on their familiarity with code of conduct, their academic experience, and their experience with the use of technology. Results of nearly 360 records show that familiarity with code of conduct and academic experience are significant predictors of ethical decision making.
Abstract: Access control is one of the most important methods for securing information storing and sharing among various RFID systems. However, there are usually many complicated RFID data types and time-dependent relationships between the data need to be considered. In this paper, we propose a policy-based access control mechanism for RFID information services. We also provide ten access control policies according to the typical access control requirements as examples for RFID-enabled businesses.

Abstract: A field study of an e-commerce project revealed patterns of IT resource adaptations used to deal with a rapidly changing business environment. The study followed managerial teams as they attempted to adapt IT resources to cope with market and partnership changes.
A genetic algorithm simulation model was then applied to help explore the field study findings and to investigate the dynamic nature of IT adaptations.
Abstract: IT-business alignment is a persistent information management concern. The Strategic Alignment Maturity (SAM) assessment instrument was used to assess maturity of management practices and strategic choices to facilitate alignment. Discriminant function equations were developed to estimate the impact of each of the SAM factors on respondents knowing their IT and business objectives. Communications and Governance Maturity were the most prominent predictors of employees knowing their objectives.
Abstract: This paper proposes a conceptual framework to examine the effects of IT infrastructure and business intelligence technologies on a firm’s information acquisition, assimilation, and exploitation processes. We posit that IT infrastructure flexibility and use of business intelligence technologies act as technological enablers to enhance absorptive capacity, which would lead to improved ambidextrous innovation competence, and consequently resulting in sustained competitive advantage.
Abstract: It may not be surprising that some different distributions of n observations across J categories yield the same value for a given measure of dispersion, i.e., the value is ambiguous. Surprisingly, though, different measures of qualitative dispersion vary markedly in their ambiguity.
Abstract: The method used to analyze data depends on the source of the data. In the process of teaching students to analyze data – not simply perform calculations – it is necessary to show them a variety of tools. This paper presents the decision tree and a format for analyzing its outputs.
Abstract: Legislative initiatives, including the Clean Water Act and the state-level Nutrient Management Act, provide a rich portfolio of policies to improve Delaware’s water quality. Yet, waters continue to be impaired. Are new policies needed or should existing policies be changed? Landowners supply water quality through their land-use behaviors in ways that do not necessarily correspond to policy designs. This paper uses AHP to assess landowners’ perceptions of the policy environment.
Abstract: We shall address the issue of the U.S. national debt and how it should be reduced. Can the U.S. federal government continue to expect its revenues to rise to the occasion? Will the retirement of seventy million baby boomers result in diminished federal revenue and increased federal expenditures? Will the changing tax structure increase federal revenues? Will these circumstances lead to an incapacity of our federal government to service its burgeoning national debt?

Abstract: New insights and questions have been generated from the reactions to the recent dissemination of a decision-making model that considers the expected positive and negative impacts of overbooking clinical appointments to compensate for patient no-shows. We examine data from 1,769 appointments in 18 outpatient clinics and develop practical recommendations for expanding service capacity and improving the service experience.
Abstract: Although there are exact equations for calculating the performance measures of some queuing models, finding the optimum number of servers is usually done through trial and error that is especially cumbersome for large service centers. This paper proposes an approximate method for finding the optimum number of servers based on the cost of servers and the cost of customer waiting. The proposed approximate model is highly accurate and, at the same time, convenient to use.
Abstract: In this exploratory research we examine the potential of archetype patterns for ontology development in health information systems (HIS) and develop initial archetype patterns. Archetype patterns are based on the integration of the concepts of archetypes and design patterns. The UML provides the underlying modeling support. Domain ontologies for intra- and inter-enterprise applications can be articulated based on archetype patterns. The patterns, in turn, can provide a foundation for semantic interoperability across HCIS applications.
Abstract: We test the random walk hypothesis in daily stock returns by a unit root test and the development of an ARIMA model for prediction. The results show that the time series of daily stock returns of firms listed on the Frankfurt exchange exhibit unit roots and have predictable components.
Abstract: Using a selection of “hot” IT topics drawn from developments in Web 2.0 and Web 3.0, we have attempted to quantify the amount of time which elapses between the publication of articles about a topic in the trade press and the appearance of articles about the same topic in peer-reviewed proceedings. We accomplish this by comparing time series data using cross correlation techniques.
Abstract: In 2006, the US Secretary of Education called for much higher levels of transparency and accountability on our campuses. This has led to many new campus wide assessment programs. At the same time, research uses computer self-efficacy to assess computer users and faculty assign grades to student work. This study applies all three of these techniques to the same body of student work. By comparing these three approaches, we hope to gain further insight into the assessment process.
Abstract: Currently, there is no formal method for measuring effectiveness of instructions. Majority of institution use the student opinion survey of a course to evaluate both an instructor and a course. There is no sound foundation to show that the method actually measures effectiveness of a course. This paper defines constructs for teaching effectiveness, and proposes a multidimensional model for measuring effectiveness. The result is a mono-number for qualitative constructs
Abstract: A common problem that many universities face, especially with their specialized programs, is coordinating faculty availability and class offerings. The schedule is usually developed using paper and pencil after numerous iterations. As a result, the objectives of the program, such as course integration, length of course and student workload, are most likely compromised in lieu of faculty availability. This paper will describe a multiple criteria approach to this class assignment problem that considers the program’s objectives and faculty preferences. The results of applying this class assignment model to an Executive MBA (EMBA) program are presented.
Abstract: The author employs a “lean” analogy to evaluate the associative data model as a potential lean database solution. The associative model of data has been proposed as a “small footprint” alternative to the highly dominant relational database model. The author presents a simple illustration of an associative data representation and evaluates it in the context of lean philosophy.
Abstract: A supply chain model involving one supplier and one dominant retailer is developed. Supply chain contracts under asymmetric information in centralized and decentralized control settings are proposed with and without disruptions. Our research shows that the supply chain contracts in centralized control setting are more optimal instruments for channel coordination.
Abstract: This paper investigates the competition of hedge fund compensation under asymmetric information on fund manager's skill by game theoretic approach. Our results provide a framework for high skilled-type hedge fund managers
to differentiate themselves through performance compensation. We evaluate the conditions when they use incentive associated with high-water mark as their type signal. We find support by analyzing 4,390 hedge funds over the period 1990-2005.
Abstract: This study focuses on the effect of evaluation mode (evaluating conjoint stimulus, either jointly or separately) and attribute-task comparability (comparable attributes and enriched attributes) on the validity of conjoint analysis. In particular, the authors argue that consumers’ preference reverse phenomena arise when they apply the heuristic evaluation strategies (the within-attribute strategy or the across-attribute strategy). This is a problem because the preference reverse will seriously (truncated -- too long)

Abstract: By investigating the Bertrand's paradox, we have found out that the paradox is just a "puzzle" rather than a "paradox", because of lacking definition of uniformly distributed straight lines. In this paper, we analyze the specious assumptions and arguments in the Bertrand's paradox, and characterize the uniform distribution of lines in a two-dimensional plane, which not only solves Bertrand's paradox but also enhances the probability theory and information theory.
Abstract: In this paper, we developed a modified Conflict Style Inventory- Preferred Conflict-Handling Mode (PCHM) to explain how individuals deal with situations in which their desires are in conflict with another individual or group. The two variables in the PCHM model are Assertiveness and Cooperativeness. Two additional interacting, independent variables were posited to affect a sudden change in subject action under situations wherein there are different views of recommended decisions.
Abstract: A discrete bilevel optimization model is presented for hierarchy decision-making in biofuel production. Government determines tax credits to encourage biofuel production in the upper level problem, while the farms allocate lands to various usages in the lower level problem.

Abstract: This study explores the relevant dimensions of organizational slack in SMEs and investigates their impact on adoption of different types of information technology innovations. Using recent data from a representative sample of 2,307 U.S. SMEs, we find that slack-innovation relationships previously uncovered in larger firms do not hold well for SMEs. Our results show that the linearity and direction of slack effects changes depending on the type of innovation and the type of slack.
Abstract: Build-to-order Supply Chain (BOSC) is viewed by many researchers as an effective way to achieve high customer value. It can be achieved through supplier partnership practices. A buyer’s structural solutions (i.e., supply chain alignment) perceived by the supplier can increase the frequency and range of supplier partnership practices. The 208 responses were collected from in North America and China. SEM is used to analyze those data. Two hypotheses are significant with high effect sizes.

Abstract: Virtual worlds such as Second Life have blossomed in recent years. Avatars of Second Life can create and trade virtual goods which have three levels of copy rights: Resell, Copy and Modify. We study the optimal pricing of copyright permissions using a two-stage game theory model under monopoly. We find that: (1) Under no-resale case, providing “Modify” and “Copy” is optimal for the monopolist; (2) Resell will not benefit the monopolist but the total welfare if the resale rate is more than 1/4.
Abstract: In spite of all the efforts of researchers to untangle the diversification-performance relationship milieu, there is still much confusion. One potential source of confusion centers on the type of diversification being pursued. It has been assumed that diversification is a one-dimensional construct. Separating diversification into two major types, product and international, the present study employs an international sample (U.S., Japan, and EEC firms).

Abstract: As lean management becomes more widely adopted, researchers and practitioners have begun to look at traditional costing systems (TCS) and its potential to undermine lean management initiatives. Meanwhile, the management accounting literature has focused on alternatives to TCS such as Activity-Based Costing (ABC) and, more recently, Resource Consumption Accounting (RCA). This paper looks to define "Lean Accounting" and examine the impact of TCS, ABC, and RCA on lean management practices.
Abstract: Although there are exact equations for calculating the performance measures of some queuing models, finding the optimum number of servers is usually done through trial and error that is especially cumbersome for large service centers. This paper proposes an approximate method for finding the optimum number of servers based on the cost of servers and the cost of customer waiting. The proposed approximate model is highly accurate and, at the same time, convenient to use.
Abstract: The minimal growth in the industry plus the over saturation, financial institutions and other sectors competing for the traditional banking products has forced banks to look at ways to control their costs to reach the profitability levels that are necessary to appease their stakeholders. ABC provides bank managers a greater understanding of the true cost and profitability of all transactions in daily processes in the bank. Our research study shows the profitability of the same loans under ABC (truncated -- too long)

Abstract: A creative environment perceptions scale is presented. The scale has good measurement properties, is brief enough for easy administration, and can be used on a wide range of “garden variety creativity” workers. Structural equation model testing indicates 3 significantly inter-related latent variables – creativity support, work characteristics, and creativity blocks. This finding indicates that managers must improve all creative environment aspects to maximize worker creative output.
Abstract: In 1997 Goldratt proposed Critical Chain as a superior alternative to PERT/CPM for managing projects in multi project environments. Several vendors have incorporated his ideas into software packages for industry use. In spite of using such systems companies continue to face the challenge of completing projects on-time and within budget. This paper extends Goldratt’s model by proposing a 2-dimensional model and a new metric that we found useful at a local company.

Abstract: In software reliability applications, research cites Ross’1985 work as a useful procedure in estimating the future error rate of software after discovered bugs are removed. The problem is:“What is the rate of occurrences of the sum of remaining Poisson random variables after variables having large enough values are removed? Or What is the reliability of a software package after bugs having a certain level of occurrence are removed? A generalization of Ross’ estimator is derived.
Abstract: In this paper, we developed a modified Conflict Style Inventory- Preferred Conflict-Handling Mode (PCHM) to explain how individuals deal with situations in which their desires are in conflict with another individual or group. The two variables in the PCHM model are Assertiveness and Cooperativeness. Two additional interacting, independent variables were posited to affect a sudden change in subject action under situations wherein there are different views of recommended decisions.
Abstract: This article presents the results of an investigation undertaken on 259 Brazilian IS/IT professionals. This exploratory study aims to familiarize researchers with the profile of these professionals by referring to their levels of hierarchical and decision-making that obey a standard hierarchical logic, namely: Operational, Tactical and Strategic. Based on the data acquired in the investigation, we sought to itemize the various aspects concerning decision-making and hierarchical issues.
Abstract: This study examines the link between leader communication and worker decision making. Results show that leader communication (as measured by the motivating language scale) is significantly and positively related to worker decision making. Structural equation model results indicate a 2.5% improvement in worker decision making for every 10% increase in leader language use. These results are useful to managers since motivating language can be easily applied to improve employee decision making.
Abstract: Students struggle with the concepts of uncertainty & variability; in project management it is critical that students can identify, understand, and manage project risk.

Abstract: Our research provides a decision supporting system for the make-to-order supply chain to facilitate the sourcing process using information about their sourcing partners’ cost and processing time. For a desired service level, a range of sourcing alternatives instead of a single optimal sourcing solution. The portfolio allows the manufacturer to make trade-offs between cost and probability to finish the job on time.
Abstract: Frequently in data analysis competing models arise from a single dataset. Choosing between model subsets is a non-trivial problem for decision-makers. In decision trees that use discretized datasets model subsets occur in two ways. Competing discretization methods create model subsets, and methods that can create different numbers of categories also create model subsets. We present an information criterion for choosing among resulting model subsets within decision trees.

Abstract: We formulate a model to examine the mix of dedicated and flexible maintenance technicians (servers) required when total delay cost is a non-linear function of mean delay time. Non-linear delay costs appear to increase the level of cross training required compared to previous research using linear costs where a small proportion of flexible servers was sufficient. This has important implications for service system designers in regard to the amount of cross training that might be appropriate.
Abstract: This paper presents a framework for analyzing load damages in a supply chain network.

Studies that have analyzed the diversification-performance relationship have shown that related diversification positively affects performance, whereas unrelated ones discounts firm performance. In this paper, we revisit the issue and argue that a mix of related and unrelated firm diversification is essential for sustainable competitive advantage.
Abstract: Markets with a highly diverse customer base provide the context within which we assess firms’ ability to develop absorptive capacity. Within this context, we discuss a conceptual model that shows theory-derived relationships between components of absorptive capacity and various aspects of diversity. Theoretical concepts from the diversity-related literature and elements of resource-based theory, upper echelons theory, and learning theory are used to support propositions derived from the model.
Abstract: We propose an inspection model that deal with three related problems: how often to inspect items, how to conduct the search, and when to stop the search process. Based on various cost factors, the problem of optimal inspection interval, optimal search process, and optimal stopping rule is formulated as a profit-maximization model via a dynamic programming approach. For the production process with a unknown failure rate, we also propose Bayesian methods of estimating the process failure rate.

Abstract: As the field of Management Information Systems matures, researchers are transitioning from models and conceptual research methods to empirical-based research techniques. One of these empirical based research techniques utilizes questionnaires to collect data from respondents. Questionnaire based empirical research techniques have been observed to exhibit many advantages especially so, when the inherent rules are implemented properly. However, there are some specific issues that, when not addressed properly may lead to misleading statistical-based results. One of these key issues pertains to how issues of missing data in the returned questionnaires are addressed. Hence, this paper aims at evaluating empirical research articles in major information systems journals in order to find out how researchers are handling issues of missing data.

Abstract: This study aims to assess the current status of entrepreneurship course offerings Colleges and Universities in Sub-Saharan Africa. The results of the study demonstrate that the majority of higher education institutions offer a course in entrepreneurship and/or small business management. Few institutions offer a specialization in the area of entrepreneurship. The promotion of entrepreneurial activities through entrepreneurship centers is not supported in most institutions.
Abstract: Many organizations have found that a by-product of lean principles is enhanced “green” or environmental performance, even when lean activities were not initiated for environmental reasons. Typically, environmental savings are not often part of the financial justification for lean improvement activities. This paper proposes a new lean principle, “sustainability.”
Abstract: Under an uncertain environment, two manufacturing strategies emerged: manufacturing system automation and manufacturing system integration. Existing case studies indicate that firms should adopt manufacturing integration first and then automate the manufacturing system to improve manufacturing performance. This study empirically supports this proposition using 303 responses from manufacturing managers.
Abstract: An active learning exercise (Case) is examined. This Case gave students an opportunity to experience teamwork, prepare written reports, make oral presentations, and evaluate peers. There was a significant difference of p = .05 between the mean scores on Exam II (before Case) and on the Final Exam (after Case). The students strongly agreed or agreed that this case increased their understanding of the financial statement analysis topics.
Abstract: Using a Hybrid Radial/NonRadial DEA approach and organizational level ecological modernization theory as our basic theoretical foundation we evaluate whether innovations in organizational practices and technological solutions achieve joint technical and environmental performance (efficiency) scores of these facilities.
Abstract: The theory and practice of Total Quality Management (TQM) have evolved over the last three decades from the technical aspects of quality control and employee training to a supply-chain-wide delivery of excellent products and services. These organizations have made tied sustainability reporting toimproved organizational performance as their primary strategic goals and objectives. The Dow Jones Sustainability Indexes (DJSI) were established to track and monitor their performance.
Abstract: If some consumers are willing to wait for inventory of a particular product to become available, sellers may be able to increase their profits by offering these consumers a price discount. Diverting the demand of customers who are willing to wait can enable the seller to reserve units of goods in short supply for those customers who are not willing to wait. This enables the seller to satisfy a larger portion of demand, and we show that this increases firm profitability in some cases.
Abstract: This study empirically investigated the role and implications of industrial maintenance in the maquiladora industry. The response rate was 86% constituting 131 usable questionnaires. Additionally, several in-depth field interviews with experts of maquiladoras were conducted in order to gain insight into the results of the survey.
Abstract: Much of Southern California was stricken by wildfires in October 2007. Subsequently, bare soil on slopes was subject to extensive erosion. The region had above normal rainfall in the following months. This paper makes the case that the fire and the resultant erosion, are a single tax disaster that straddles the calendar year end, the tax loss being deductible in the year the casualty ends.
Abstract: SAP-University Alliance Program enabled a Business School to revise the business curriculum in incorporating ERP concepts. Every student in the College of Business is exposed to SAP R/3 through an incremental integration approach. The paper describes the approach and presents some results of SAP R/3 implementation.
Abstract: Past research indicates that most firms face problems in successfully implementing their ERP systems. In this paper, we suggest that the above could be due to a lack of “systemic” understanding of ERP system deployments. To address this issue, we use a theoretical framework, adapted from literature, to discuss the systemic perspective that underlies the ERP system. The approach to ERP developed here provides insights for both research and practice.
Abstract: ERP is a critical strategic tool to achieve business goals. To prevent ERP failures, proper adoption processes and selection criteria should be considered. This paper suggests a conceptual framework including antecedents of ERP adoption and attitude and intention toward it. To validate the model, five ERP failure cases were examined.

Abstract: This case examines the consequences of an early morning pre-season, bar-room altercation between two professional athletes, which left one player with career threatening injuries. It can be used to explore issues of ethical and moral behavior at multiple levels relating to individual athletes, team management, and franchise and national body governance. It may also be used to explore issues of risk, crisis and media management.
Abstract: Ethical decision making was investigated in various disciplines. However, with the growing popularity of the Internet, new ethical challenges emerge. A framework was developed for students’ ethical decision making based on their familiarity with code of conduct, their academic experience, and their experience with the use of technology. Results of nearly 360 records show that familiarity with code of conduct and academic experience are significant predictors of ethical decision making.
Abstract: The ethics of tax evasion has been discussed in the theological/philosophical literature for at least 500 years. Martin Crowe wrote a thesis in 1944 that reviewed this literature. But the business ethics literature has paid scant attention to this issue. This paper reports survey results of business students in Utah and New Jersey to determine their agreement with the 15 arguments that Crowe identified plus three more recent ones. Responses were ranked and scores were compared between samples.
Abstract: The objective of this study is to investigate the strategic approaches utilized by Portuguese manufacturing organizations in response to the competitive pressures in the European and global markets. Based on the results of the analysis, it appears that the sampled organizations are following hybrid strategic orientations. These strategic orientations appear to be motivated by well-defined mixed strategies. The strategic elements of e-business are detected in these mixed strategies.
Abstract: This study focuses on the effect of evaluation mode (evaluating conjoint stimulus, either jointly or separately) and attribute-task comparability (comparable attributes and enriched attributes) on the validity of conjoint analysis. In particular, the authors argue that consumers’ preference reverse phenomena arise when they apply the heuristic evaluation strategies (the within-attribute strategy or the across-attribute strategy). This is a problem because the preference reverse will seriously (truncated -- too long)
Abstract: Currently, there is no formal method for measuring effectiveness of instructions. Majority of institution use the student opinion survey of a course to evaluate both an instructor and a course. There is no sound foundation to show that the method actually measures effectiveness of a course. This paper defines constructs for teaching effectiveness, and proposes a multidimensional model for measuring effectiveness. The result is a mono-number for qualitative constructs
Abstract: Despite the growing recognition of the importance of IS security quality, the financial benefits of IS security quality are being questioned by cost-cutting executives. Interestingly little effort has been made to examine the relationship between IS security quality and firm performance. In this study we investigate the relationship by examining the effect of IS security incidents on long-term and short-term firm performances after controlling for a variety of industry and firm-specific factors.
Abstract: This article explores the theories of exceedances and extreme values and their application to sports. The material deviates from that taught in introductory statistics courses as it concentrates on the frequency and values of extremes and the situations where extremes are of greater concern than averages. It is hoped the instructors of statistics will find this article of some value for teaching statistics and for its focus on a popular motivating theme, sports.
Abstract: Hong and Hayya [1] developed an Excel model with VBA to find an optimal transportation scheme for a practical transportation model, which assumes unrestricted shipments between supply or demand points and assumes that a fixed cost is incurred every time a shipment from a supply point to another supply point or a demand point is made. In the present paper, we now apply the set-covering model using Excel with VBA and develop a heuristic to solve the transportation problem in [1].
Abstract: About half of IS studies employ a measure of experience as part of the research model, as a descriptor of the sample of participants, or as a qualitative limitation on subject selection. This research discusses the notion of experience as a latent construct, and reviews a number of important issues that need be considered in future uses of the concept.

Abstract: This study examines the relationships between HR, market orientation and manufacturing strategies, and competitive strategy and their impact on performance. We examine these relationships for family and nonfamily firms in a developing economy. An HR participation strategy is closely associated with both cost leadership and differentiation strategies for family firms. Family firms are more likley to gain sales growth and profitability benefits if they emphasize a delivery strategy.
Abstract: As a result of intense competition fast-food restaurants are increasingly recognizing the importance to continuously improve their service quality to attract and retain customers. This study explores the potential dimensions of service quality, and examines the relationships among service quality, food quality, price/value, customer satisfaction and behavioral intentions in fast-food restaurants (FFRs) in China.
Abstract: We shall address the issue of the U.S. national debt and how it should be reduced. Can the U.S. federal government continue to expect its revenues to rise to the occasion? Will the retirement of seventy million baby boomers result in diminished federal revenue and increased federal expenditures? Will the changing tax structure increase federal revenues? Will these circumstances lead to an incapacity of our federal government to service its burgeoning national debt?
Abstract: We extend Ryan et al.'s (1983) study on the interaction between feedback and reward to a DSS context. Our findings indicate a differential effect from their study when feedback is provided through a DSS and the focus is on decision performance rather than the precursor condition of intrinsic motivation.
Abstract: As IS researchers, we are interested in exploring the possibilities of rebuilding trust and relationships through a good fit between technology and management processes. With increased level of richness and reach of information facilitated by technology in the domain of ecommerce, the rectifications, which were earlier very difficult, are now becoming achievable. Policies once thought not viable by e-commerce organizations, due to technology constraints are now increasingly being adopted. The fi(truncated -- too long)
Abstract: We formulate a model to examine the mix of dedicated and flexible maintenance technicians (servers) required when total delay cost is a non-linear function of mean delay time. Non-linear delay costs appear to increase the level of cross training required compared to previous research using linear costs where a small proportion of flexible servers was sufficient. This has important implications for service system designers in regard to the amount of cross training that might be appropriate.
Abstract: Computer-based multitasking behavior has become commonplace, however its effiacy in face-to-face meetings is disputed. We conceptualize and operationalize multitasking use behavior in terms of on-task and off-task uses. Our research objective is to examine a provisioning system’s effectiveness with respect to restraining off-task uses while leaving on-task uses unaffected.
Abstract: This study investigates the influence of R&D expenditure on the corporate value of Japanese manufacturing industry. DEA-DA is the methodology for the study. This research finds that the R&D expenditure is important for the Japanese manufacturing industries to be competitive in a global market. However, the importance of R&D expenditure depends upon the type of industry.
Abstract: The problem of estimating an unknown change-point in the parameters of a sequence of independent d-dimensional time-series valued random variables from a general parametric family of distributions is considered. Adapting the estimation methodology of abrupt changes, we develop theory for deriving the asymptotic distribution of the MLE of the change-point under the contiguity condition. We apply the methodology to estimate the change-point for the daily log-returns of stocks from the NYSE.
Abstract: In this paper, we illustrate the use of data envelopment analysis, an operations research technique, to analyze financial statements of financial services firms by benchmarking financial ratios of a firm against its peers as well as against the industry averages. Data envelopment analysis clearly brings out the firms that are operating more efficiently in comparison to other firms in the industry, and points out the areas in which poorly performing firms need to improve.
Abstract: Governments are not required to present an aggregated amount for current assets in the statements of net assets. The authors believe this disclosure is essential to assess the liquidity component of a government’s financial position. This article presents a case for the GASB to revisit the current asset disclosure requirements.
Abstract: The present study proposes and tests a model explaining the relationship between organizational characteristics and the presence of champions using a survey of senior executives in the healthcare industry. The result reveals that organizational technology knowledge is a major determinant of the presence of champions.

Abstract: This study examines the relationships between HR, market orientation and manufacturing strategies, and competitive strategy and their impact on performance. We examine these relationships for family and nonfamily firms in a developing economy. An HR participation strategy is closely associated with both cost leadership and differentiation strategies for family firms. Family firms are more likley to gain sales growth and profitability benefits if they emphasize a delivery strategy.
Abstract: A theoretical model of the impact of several workforce management practices on workforce agility is developed and tested. Plants that emphasized process-focused training, provided greater on-the-job training through rotation practices, maintained better labor climate and designed a positive reward structure experienced higher workforce agility. Plants with higher workforce agility were more likely to transfer their employees to temporary bottleneck areas, resulting in improved plant performance.
Abstract: Maintaining an adequate supply of graduates is a pressing concern for the accountingfield and identifying ways of improving student persistence is one method that should be explored. One reason that students do not persist in completing the degree may be that they are not satisfied with their experience. Flexible grading allows students to make choices regarding the type of assignments they will complete. This study examined students’ satisfaction with flexible grading schemes.

Abstract: We apply three smoothing techniques – weighted moving average, simple exponential smoothing, Syntetos-Boylan approximation – and neural network modeling to 24 time series of products exhibiting lumpy demand. For the weighted moving average technique, we determined optimal weights for each of the 24 series using standardized ordinary least squares regression applied to five lagged period demands as predictor variables. We compared forecasting methods using three accuracy measures.
Abstract: In software reliability applications, research cites Ross’1985 work as a useful procedure in estimating the future error rate of software after discovered bugs are removed. The problem is:“What is the rate of occurrences of the sum of remaining Poisson random variables after variables having large enough values are removed? Or What is the reliability of a software package after bugs having a certain level of occurrence are removed? A generalization of Ross’ estimator is derived.
Abstract: Among the business processes used for sustainability is reuse. A key component of reuse is remanufacturing. We consider a manufacturer/remanufacturer, and develop a generalized forecasting approach to determine the returns of used products, as well as integrate with an inventory model to enable production planning and control.
Abstract: The hotel industry has a history of employing revenue management to enhance profits. Hotel managers’ performance is measured by revenue, cost, and quality. Hotel managers set availability restrictions and price for hotel rooms but have little control of costs. Our research focuses on forecasting in hotel revenue management.
Abstract: This paper describes the development and relevance of the coefficient of prediction, P2. The coefficient of prediction is independent from the quality of fit. This paper shows evidence of the gain in accuracy and precision in the estimate of the quality of prediction when using P2.
Abstract: This paper investigates decision factors that affect the forecasting accuracy of airline seat demand. Of particular interest are the aggregation levels of demand across fare classes and time horizons. Several traditional forecasting methods are evaluated in addition to a new method. Results suggest that differences in demand are not relevant to forecasting accuracy and that a finely disaggregated fare class system enhances accuracy. Future research directions based on these findings include enhanced focus on lost demand and cancelled reservations that capture these dynamics.
Abstract: Most new product forecasting models require the estimation of parameters for their use. In this paper, we evaluate 3 techniques to determine the parameters of the Bass diffusion model.

Abstract: Devices that integrate multiple functions (fusion products) are popular in consumer electronic markets. In this paper, we investigate the manufacturer's fusion product design decision. The results demonstrate that the manufacturer should select only a subset of fusion and single-function products to satisfy the market's multi-dimension needs.
Abstract: We examined the volatility persistence feature in high-frequency returns and test the Mixture-of-Distribution Hypothesis using transaction data of the Japanese Government Bond futures. Both time-domain and frequency-domain methods show that the degrees of volatility persistence are very similar across various frequencies, which supports the hypothesis.
Abstract: This paper proposes an application of fuzzy non- linear goal programming (FNLGP) model for inventory management decision-making using tolerance allowance fuzzy goal programming (TFGP) technique to determine the economic order quantity (EOQ) in a multi-item inventory problem. The proposed model is derived based on fuzzy goals such as budget, warehouse space and amount of investment which are critical to a decision-making process. In TGFP modeling, these goals are converted in to deterministic goa(truncated -- too long)
Abstract: Virtual worlds such as Second Life have blossomed in recent years. Avatars of Second Life can create and trade virtual goods which have three levels of copy rights: Resell, Copy and Modify. We study the optimal pricing of copyright permissions using a two-stage game theory model under monopoly. We find that: (1) Under no-resale case, providing “Modify” and “Copy” is optimal for the monopolist; (2) Resell will not benefit the monopolist but the total welfare if the resale rate is more than 1/4.
Abstract: Drop-shipping is an arrangement whereby an e-tailer, who does hold inventories, processes orders and requests a manufacturer/distributor to ship products directly to the customers. This research studies the efficiency of the drop-shipping channel compared to the traditional channel. We identify conditions under which the drop-shipping channel outperforms the traditional channel.
Abstract: The supply network, as a more practical extension of supply chain, comprises of multiple interconnected supply chains.

Abstract: In this exploratory research we examine the potential of archetype patterns for ontology development in health information systems (HIS) and develop initial archetype patterns. Archetype patterns are based on the integration of the concepts of archetypes and design patterns. The UML provides the underlying modeling support. Domain ontologies for intra- and inter-enterprise applications can be articulated based on archetype patterns. The patterns, in turn, can provide a foundation for semantic interoperability across HCIS applications.
Abstract: This paper develops a technique to compare capacities of different types of resources within a hospital system so that appropriate system capacity can be derived in order to improve system efficiencies and add value of care provided. Overall, the techniques presented in this paper would help hospitals increase efficiency of healthcare delivery (increase throughput) and reduce waste (underutilization of resources), while not compromising with quality of care, safety and access.
Abstract: Strategic alliances in the form of interorganizational networks continue to receive attention in service industries as a potential form of competitive advantage.

Abstract: We present a method for a single machines with sequence dependent setups where the objective is to minimize the total setup time. We illustrate the method for an industrial problem. Hierarchical Composition Heuristic is a two-stage method that takes advantage of the natural product families. It should be a valuable scheduling tool for environments that manufacture families of items.
The simplicity, and quickness of the solution procedure should make it appealing for industrial applications.
Abstract: Hong and Hayya [1] developed an Excel model with VBA to find an optimal transportation scheme for a practical transportation model, which assumes unrestricted shipments between supply or demand points and assumes that a fixed cost is incurred every time a shipment from a supply point to another supply point or a demand point is made. In the present paper, we now apply the set-covering model using Excel with VBA and develop a heuristic to solve the transportation problem in [1].

The results of the test show that the existing heuristics are inconsistent and the genetic algorith is better.
Abstract: Of the three heuristics (policies) Naddor has developed, we test the performance of his (s,S) policy on the spare parts problem. His (t,Z)and (s,q)heuristics are also discussed since they are essential in understanding the (s,S)policy. We compare the performance of his (s,S) policy with the optimal solutions to the problem obtained by the Archibald- Silver algorithm. The data used were collected from a Fortune 500 Company. Further sensitivity analysis is done by varying some of the parameters in the data. Our research extends Naddor’s preliminary comparisons in 1975, which were limited in nature.
Abstract: An iterative, matrix-analytic heuristic is proposed for dynamically allocating additional resources to tasks in a project network at various points in the project's evolution so as to provide time buffers in order to maximize the probability of timely project completion.
Abstract: In this paper we address the problems of developing inventory policies for supply chain members (Manufacturer-Distributor-Retailer: M-D-R) in a stochastic Bi-level retail demand environment. Considering all relevant tradeoffs, we develop three ordering policies, namely, Moving Average (MAP), Target Inventory Level (TILP), and Complete Cooperation (CCP), suitably modified for each member of the supply chain. We used simulation to estimate the relative performance of policies & report our findings
Abstract: Legislative initiatives, including the Clean Water Act and the state-level Nutrient Management Act, provide a rich portfolio of policies to improve Delaware’s water quality. Yet, waters continue to be impaired. Are new policies needed or should existing policies be changed? Landowners supply water quality through their land-use behaviors in ways that do not necessarily correspond to policy designs. This paper uses AHP to assess landowners’ perceptions of the policy environment.

Using logistic regression model, results indicate that CSE and UI were significant predictor on implementation success.
Abstract: As the field of Management Information Systems matures, researchers are transitioning from models and conceptual research methods to empirical-based research techniques. One of these empirical based research techniques utilizes questionnaires to collect data from respondents. Questionnaire based empirical research techniques have been observed to exhibit many advantages especially so, when the inherent rules are implemented properly. However, there are some specific issues that, when not addressed properly may lead to misleading statistical-based results. One of these key issues pertains to how issues of missing data in the returned questionnaires are addressed. Hence, this paper aims at evaluating empirical research articles in major information systems journals in order to find out how researchers are handling issues of missing data.

Abstract: We propose an inspection model that deal with three related problems: how often to inspect items, how to conduct the search, and when to stop the search process. Based on various cost factors, the problem of optimal inspection interval, optimal search process, and optimal stopping rule is formulated as a profit-maximization model via a dynamic programming approach. For the production process with a unknown failure rate, we also propose Bayesian methods of estimating the process failure rate.

Abstract: Of the three heuristics (policies) Naddor has developed, we test the performance of his (s,S) policy on the spare parts problem. His (t,Z)and (s,q)heuristics are also discussed since they are essential in understanding the (s,S)policy. We compare the performance of his (s,S) policy with the optimal solutions to the problem obtained by the Archibald- Silver algorithm. The data used were collected from a Fortune 500 Company. Further sensitivity analysis is done by varying some of the parameters in the data. Our research extends Naddor’s preliminary comparisons in 1975, which were limited in nature.
Abstract: Drop-shipping is an arrangement whereby an e-tailer, who does hold inventories, processes orders and requests a manufacturer/distributor to ship products directly to the customers. This research studies the efficiency of the drop-shipping channel compared to the traditional channel. We identify conditions under which the drop-shipping channel outperforms the traditional channel.
Abstract: If some consumers are willing to wait for inventory of a particular product to become available, sellers may be able to increase their profits by offering these consumers a price discount. Diverting the demand of customers who are willing to wait can enable the seller to reserve units of goods in short supply for those customers who are not willing to wait. This enables the seller to satisfy a larger portion of demand, and we show that this increases firm profitability in some cases.

Abstract: From a supplier’s perspective, this paper explores electronic collaboration based on IOIS implemented by a dominant buyer, and key factors to increase levels of relational orientation and firm performance in vertical buyer-supplier relationships. A set of 178 data from SMEs(Small Medium Enterprises) transacting with a dominant buyer in Korea was used for SEM analysis. Results show that e-collaboration is affected by the existing off-line relationships like relationship-specific investments.
Abstract: A challenge to successfully implement a selective outsourcing is to ensure that IS infrastructure (or some parts of it) and associated business processes could be reliably outsourced and then at the same time smoothly and seamlessly integrated with other outsourced or in-sourced IS and business components. To meet this challenge, we propose that IS architecture planning can play the role of enabling both reliable outsourcing and seamless integration of outsourced and in-sourced IS/business components to ensure IS outsourcing effectiveness.
Abstract: Despite the growing recognition of the importance of IS security quality, the financial benefits of IS security quality are being questioned by cost-cutting executives. Interestingly little effort has been made to examine the relationship between IS security quality and firm performance. In this study we investigate the relationship by examining the effect of IS security incidents on long-term and short-term firm performances after controlling for a variety of industry and firm-specific factors.

Abstract: This paper identified risk factors inherent in each phase of the IS outsourcing life cycle. Any company conducting IS outsourcing must recognize the success and risk factors, conduct risks analysis, and implement quality control process during outsourcing life cycle to make it a successful one.
Abstract: A challenge to successfully implement a selective outsourcing is to ensure that IS infrastructure (or some parts of it) and associated business processes could be reliably outsourced and then at the same time smoothly and seamlessly integrated with other outsourced or in-sourced IS and business components. To meet this challenge, we propose that IS architecture planning can play the role of enabling both reliable outsourcing and seamless integration of outsourced and in-sourced IS/business components to ensure IS outsourcing effectiveness.
Abstract: Despite the growing recognition of the importance of IS security quality, the financial benefits of IS security quality are being questioned by cost-cutting executives.

Abstract: A theoretical model of the impact of several workforce management practices on workforce agility is developed and tested. Plants that emphasized process-focused training, provided greater on-the-job training through rotation practices, maintained better labor climate and designed a positive reward structure experienced higher workforce agility. Plants with higher workforce agility were more likely to transfer their employees to temporary bottleneck areas, resulting in improved plant performance.
Abstract: Cross-trained workers can provide two important advantages for service delivery systems: improved robustness and increased worker utilization. However, these insights arose from studies of service delivery environments where all workers begin and end their shifts at the same time, and never call in sick. This research examines cross-training policies for service environments with uncertain demand, unreliable workers and scheduling flexibility options such as overlapping shifts.
Abstract: We consider the change-point problem in which a change occurs in the mean only of an independent Gaussian sequence. As a sequel to Hinkley’s asymptotic approach, we derive an exact computable expression for the asymptotic distribution of the maximum likelihood estimate of the unknown change-point. The derivation is based on ladder heights of Gaussian random walks hitting the half-line.
Abstract: We embed the change-point problem into a stochastic system in which the input process is Poisson by allowing the underlying inter-arrival exponential rates to change subsequent to an unknown index of time. Adapting Hinkley’s set up of the change-point problem, we derive explicit computable expressions for the asymptotic distribution of the maximum likelihood estimate of the unknown change-point. The analytical approach is based on application of the theory of random walks hitting the half-line.
Abstract: The study attempts to find out the nature of attributes, consequences and consumer values in the multi-channel shopping (MCS) context. It constructs a value-driven hierarchical model for MCS. In this study, we review literature pertaining to MCS and consumer values to derive a means-end model for MCS. Two studies are designed to explore and construct the value-driven hierarchy of MCS. Finally, managerial implications, research directions and limitations are discussed.
Abstract: Using a selection of “hot” IT topics drawn from developments in Web 2.0 and Web 3.0, we have attempted to quantify the amount of time which elapses between the publication of articles about a topic in the trade press and the appearance of articles about the same topic in peer-reviewed proceedings. We accomplish this by comparing time series data using cross correlation techniques.
Abstract: Although there are exact equations for calculating the performance measures of some queuing models, finding the optimum number of servers is usually done through trial and error that is especially cumbersome for large service centers. This paper proposes an approximate method for finding the optimum number of servers based on the cost of servers and the cost of customer waiting. The proposed approximate model is highly accurate and, at the same time, convenient to use.

Abstract: This study examines the link between leader communication and worker decision making. Results show that leader communication (as measured by the motivating language scale) is significantly and positively related to worker decision making. Structural equation model results indicate a 2.5% improvement in worker decision making for every 10% increase in leader language use. These results are useful to managers since motivating language can be easily applied to improve employee decision making.
Abstract: This study investigates the relationship between strategic leader language (as embodied in Motivating Language Theory) and employee absenteeism. Structural equation modeling measured two perspectives for the impact of leader spoken language: employee absenteeism attitudes and actual attendance. Results suggest that leader language does in fact have a positive, significant relationship with work attendance. However, no similar effect was reported for employee attitudes towards absenteeism.
Abstract: This paper attempts to explore the key antecedents (KAs)of service offshoring deriving from outsourcing literatures. In addition, how top management will form the attitude/norms that are critical for the offshoring decision, how these will affect intention and behavior to decision-making for service offshoring will be examined using Theory of Reasoned Action. Finally, three regulatory factors (i.e., moderating factor that will affect the relationship between KAs and decision)will be presented.
Abstract: Many organizations have found that a by-product of lean principles is enhanced “green” or environmental performance, even when lean activities were not initiated for environmental reasons. Typically, environmental savings are not often part of the financial justification for lean improvement activities. This paper proposes a new lean principle, “sustainability.”
Abstract: The author employs a “lean” analogy to evaluate the associative data model as a potential lean database solution.

Abstract: This paper investigates decision factors that affect the forecasting accuracy of airline seat demand. Of particular interest are the aggregation levels of demand across fare classes and time horizons. Several traditional forecasting methods are evaluated in addition to a new method. Results suggest that differences in demand are not relevant to forecasting accuracy and that a finely disaggregated fare class system enhances accuracy. Future research directions based on these findings include enhanced focus on lost demand and cancelled reservations that capture these dynamics.

Abstract: A common problem that many universities face, especially with their specialized programs, is coordinating faculty availability and class offerings. The schedule is usually developed using paper and pencil after numerous iterations. As a result, the objectives of the program, such as course integration, length of course and student workload, are most likely compromised in lieu of faculty availability. This paper will describe a multiple criteria approach to this class assignment problem that considers the program’s objectives and faculty preferences. The results of applying this class assignment model to an Executive MBA (EMBA) program are presented.
Abstract: The problem of estimating an unknown change-point in the parameters of a sequence of independent d-dimensional time-series valued random variables from a general parametric family of distributions is considered. Adapting the estimation methodology of abrupt changes, we develop theory for deriving the asymptotic distribution of the MLE of the change-point under the contiguity condition. We apply the methodology to estimate the change-point for the daily log-returns of stocks from the NYSE.
Abstract: We consider the change-point problem in which a change occurs in the mean only of an independent Gaussian sequence. As a sequel to Hinkley’s asymptotic approach, we derive an exact computable expression for the asymptotic distribution of the maximum likelihood estimate of the unknown change-point. The derivation is based on ladder heights of Gaussian random walks hitting the half-line.
Abstract: We embed the change-point problem into a stochastic system in which the input process is Poisson by allowing the underlying inter-arrival exponential rates to change subsequent to an unknown index of time. Adapting Hinkley’s set up of the change-point problem, we derive explicit computable expressions for the asymptotic distribution of the maximum likelihood estimate of the unknown change-point. The analytical approach is based on application of the theory of random walks hitting the half-line.

Abstract: As the field of Management Information Systems matures, researchers are transitioning from models and conceptual research methods to empirical-based research techniques. One of these empirical based research techniques utilizes questionnaires to collect data from respondents. Questionnaire based empirical research techniques have been observed to exhibit many advantages especially so, when the inherent rules are implemented properly. However, there are some specific issues that, when not addressed properly may lead to misleading statistical-based results. One of these key issues pertains to how issues of missing data in the returned questionnaires are addressed. Hence, this paper aims at evaluating empirical research articles in major information systems journals in order to find out how researchers are handling issues of missing data.

Abstract: Frequently in data analysis competing models arise from a single dataset. Choosing between model subsets is a non-trivial problem for decision-makers. In decision trees that use discretized datasets model subsets occur in two ways. Competing discretization methods create model subsets, and methods that can create different numbers of categories also create model subsets. We present an information criterion for choosing among resulting model subsets within decision trees.
Abstract: We develop the model for optimal determination of service capacity. Assuming poisson arrivals and exponential service, model minimizes the total cost which is sum of inventory holding and service capacity cost. From sensitivity analysis results we found that underestimation of arrival rate is costlier than overestimation. Still in both cases cost penalty is convex. Thus our model is simple, easy to use, robust with respect to estimation errors, and is of practical significance.
Abstract: This paper develops a size moderated stakeholder model and applies it to a facility’s adoption of proactive environmental practices (PEP). Using international empirical data, we support the idea that stakeholder pressures are positively related with the adoption PEPs. However, smaller facilities are more responsive to internal, societal and regulatory stakeholder pressures. Researchers therefore should be cautious about associating stakeholder pressures directly with environmental strategy.
Abstract: The purpose of this paper is to forward a conceptualization of information technology (IT) infrastructure as a portfolio of IT infrastructure services that can be dynamically reconfigured and rebalanced to adapt to evolving opportunities.

Abstract: This study examines the link between leader communication and worker decision making. Results show that leader communication (as measured by the motivating language scale) is significantly and positively related to worker decision making. Structural equation model results indicate a 2.5% improvement in worker decision making for every 10% increase in leader language use. These results are useful to managers since motivating language can be easily applied to improve employee decision making.
Abstract: This study investigates the relationship between strategic leader language (as embodied in Motivating Language Theory) and employee absenteeism. Structural equation modeling measured two perspectives for the impact of leader spoken language: employee absenteeism attitudes and actual attendance. Results suggest that leader language does in fact have a positive, significant relationship with work attendance. However, no similar effect was reported for employee attitudes towards absenteeism.
Abstract: This article describes an idea for motivating students in an introductory probability and statistics course.

Then, we look at some applications of new media in selected disciplines. This overview provides a framework for scholars working in this field of study.
Abstract: In the corporate world, with its global, competitive environment, many firms have become learning organizations in order to survive and thrive. Similarly, 21st century universities that succeed will be lean, flexible, and nimble; Peter Drucker once asserted that in the not-so-distant future “big universities will be relics” and will not survive. This paper explains how universities can use the new media technologies to transform themselves into true learning organizations.

Abstract: This paper outlines a unique and very successful student internship experience for students in information systems programs. This internship is an onshore alternative for companies looking for alternatives to offshore outsourcing of IS projects. The unique feature of this model is the partnership formed between a university and its industry partner. The industry partner uses the university and students as an “outsourcing” agent to complete both software testing and software development tasks.
Abstract: The evolution of offshore outsourcing has led many organizations to examine the productivity of offshore vendors. It is important for organizations to easily identify which projects should be offshored, and which should be completed by in-house development staffs. This paper reviews the history of offshore outsourcing, advantages of sending projects offshore, current issues of offshoring, and then proposes a framework to assist organizations in determining which projects should be offshored.
Abstract: This preliminary empirical study, using data from 131 offshored IS projects over a period of time and using a matched pair technique with non-offshored IS projects based on project size and other criteria, finds that work efforts expanded for offshored and non-offshored projects vary in different stages of the project.
