INFORMATION CHANNEL DISPOSITION AND USE*
Decision Sciences - Tập 18 Số 1 - Trang 131-145 - 1987
E. Burton Swanson
ABSTRACTThe use of information channels by individuals in organizations is substantially discretionary. Although much studied, variation in patterns of discretionary use has yet to be explained adequately in terms of an accepted integrative theory validated across varieties of channel types and organizational settings. In a step toward the development of such a theory, the present paper proposes a... hiện toàn bộ
Decision Making in an Automated Environment: The Effects of Anonymity and Proximity with a Group Decision Support System*
Decision Sciences - Tập 22 Số 2 - Trang 266-279 - 1991
Leonard M. Jessup, David A. Tansik
Recent advances in information systems technology have made it possible to support the work of interacting groups using networked personal computers. A laboratory experiment was conducted using a group decision support system to evaluate effects of anonymity and proximity on group process in automated group problem solving. Twenty groups of four persons each performed an idea‐generating task using... hiện toàn bộ
Interorganizational Governance Value Creation: Coordinating for Information Visibility and Flexibility in Supply Chains*
Decision Sciences - Tập 38 Số 4 - Trang 647-674 - 2007
Eric T.G. Wang, Hsiao Lan Wei
ABSTRACTMore thoroughly understanding how interorganizational governance value can be created by information technology and other governance mechanisms is critical for supply chain management. Based primarily on transaction‐cost economics and supplemented by the resource‐based view, this study investigates how interorganizational governance (i.e., relational governance and virtual integration) can... hiện toàn bộ
Supply Management Under High Goal Incongruence: An Empirical Examination of Disintermediation in the Aerospace Supply Chain
Decision Sciences - Tập 39 Số 3 - Trang 507-540 - 2008
Christian L. Rossetti, Thomas Y. Choi
ABSTRACTAftermarket sales and profits are becoming an increasingly important part of an original equipment manufacturer's (OEM) business model. Because replacement parts often do not require further manufacturing, OEMs act as intermediaries in the aftermarket. As with any intermediary, the OEM must concern itself with suppliers disintermediating its supply chain selling replacement parts directly ... hiện toàn bộ
Sequential and Simultaneous Decision Making for Optimizing Health Care Resource Flexibilities
Decision Sciences - Tập 40 Số 2 - Trang 295-326 - 2009
Adelina Gnanlet, Wendell Gilland
ABSTRACTHealth care administrators commonly employ two types of resource flexibilities (demand upgrades and staffing flexibility) to efficiently coordinate two critical internal resources, nursing staff and beds, and an external resource (contract nurses) to satisfy stochastic patient demand. Under demand upgrades, when beds are unavailable for patients in a less acute unit, patients are upgraded ... hiện toàn bộ
Reexamining the Nurse Scheduling Problem: Staffing Ratios and Nursing Shortages*
Decision Sciences - Tập 37 Số 1 - Trang 39-70 - 2006
P. Daniel Wright, Kurt M. Bretthauer, Murray J. Côté
ABSTRACTLegislators at the state and national levels are addressing renewed concerns over the adequacy of hospital nurse staffing to provide quality care and ensure patient safety. At the same time, the well‐known nursing shortage remains an ongoing problem. To address these issues, we reexamine the nurse scheduling problem and consider how recent health care legislation impacts nursing workforce ... hiện toàn bộ
Capacity Management in Health Care Services: Review and Future Research Directions*
Decision Sciences - Tập 19 Số 4 - Trang 889-919 - 1988
Vicki L. Smith‐Daniels, Sharon Schweikhart, Dwight E. Smith‐Daniels
ABSTRACTHealth care has undergone a number of radical changes during the past five years. These include increased competition, fixed‐rate reimbursement systems, declining hospital occupancy rates, and growth in health maintenance organizations and preferred provider organizations. Given these changes in the manner in which health care is provided, contracted, and paid for, it is appropriate to rev... hiện toàn bộ
Testing the Interaction Effects of Task Complexity in Computer Training Using the Social Cognitive Model
Decision Sciences - Tập 32 Số 1 - Trang 1-20 - 2001
Melesa Altizer Bolt, Larry N. Killough, Hian Chye Koh
AbstractUsing a Modified Social Cognitive Theory framework, this study examines the behavior modeling and lecture‐based training approaches to computer training. It extends the existing Social Cognitive Model for computer training by adding the task complexity construct to training method, prior performance, computer self‐efficacy, outcome expectations, and performance. A sample of 249 students fr... hiện toàn bộ
Impact of Service‐Dominant Orientation on the Innovation Performance of Technology Firms: Roles of Knowledge Sharing and Relationship Learning
Decision Sciences - Tập 51 Số 3 - Trang 620-654 - 2020
Hing Leung Yiu, Eric W.T. Ngai, Chun Lei
ABSTRACTAlthough the adoption of service‐dominant logic contributes to the innovativeness of organizations, the relationship between service‐dominant logic and innovation performance has seldom been empirically investigated. To fill this literature gap, this study used relationship learning theory to examine the effects of service‐dominant orientation (SDO), knowledge sharing, and external network... hiện toàn bộ
APPLICATION OF AN EXPECTED COVERING MODEL TO EMERGENCY MEDICAL SERVICE SYSTEM DESIGN*
Decision Sciences - Tập 13 Số 3 - Trang 416-439 - 1982
Mark S. Daskin
ABSTRACTThe Emergency Medical Service (EMS) Act specifies the fraction of all demands for service that must be reached in a given amount of time for urban and rural areas. The conditions have traditionally been interpreted to apply to the case in which all EMS vehicles are available to respond to demands. A model that considers the probability of a vehicle being busy is formulated and model proper... hiện toàn bộ
