Recent work suggests that fluctuations in dopamine delivery at target structures represent an evaluation of future events that can be used to direct learning and decision-making. To examine the behavioral consequences of this interpretation, we gave simple decision-making tasks to 66 human subjects and to a network based on a predictive model of mesencephalic dopamine systems. The human subject...

E-service involves the delivery of useful services through information technology based service delivery channels such as the Internet. A distinguishing feature of e-service is the active and significant participation of customers in the service co-production process. With increasing customer participation in the e-service co-production process, it is important to incorporate customers’ needs b...

OBJECTIVE To assess neonatologists' attitudes and practices regarding treatment of extremely preterm infants in the delivery room, particularly in response to parental wishes. STUDY DESIGN Cross-sectional survey of all neonatologists in Sweden registered with the Swedish Pediatric Society. RESULTS The response rate was 71% (88 of 124 neonatologists). At 24[1/7] to 24[6/7] weeks of gestation...

Hospitals often retain inadequate systems because they are concerned about the organisational and financial cost of IT investments that do not clearly lead to increased revenue. Previous work has not carefully examined the health care, organisational and business process issues caused by widespread under-investment in Health Information Systems, leading to compromised decision making. Methods: ...

The management of a patient presenting with unsatisfactory labor epidural analgesia poses a severe challenge for the anesthetist wanting to provide safe anesthetic care for a cesarean delivery. Early recognition of unsatisfactory labor analgesia allows for replacement of the epidural catheter. The decision to convert labor epidural analgesia to anesthesia for cesarean delivery is based on the u...

To increase the efficiency of delivery operations in small package shipping (SPS), numerous optimization models for route and location planning decisions have been proposed. This "operations research view" of defining independent problems has two major shortcomings: First, most models from literature neglect crucial real-world characteristics, thus making them useless for small package shippers...

Postal logistics has a complex transportation network for efficient mail delivery. Therefore, a postal logistics network consists of various functional sites with a hybrid hub-and-spoke structure. More specifically, there are multiple Delivery & Pickup Stations (D&PSs), multiple Mail Processing Centers (MPCs), and one Exchange Center (EC). In this paper, we develop two mathematical models with ...

One can find enough evidence in the IS development (ISD) literature supporting the significance of method adaptation for the realization of an effective ISD. Method adaptation involves a decision making process through which the agent(s) modifies the project situation, including the method and the project context, at hand. This paper aims at exploring how a better delivery of guidance and advic...
