PURPOSE Prior to the implementation of arterial spin labeling (ASL) in clinical multi-center studies, it is important to establish its status quo inter-vendor reproducibility. This study evaluates and compares the intra- and inter-vendor reproducibility of pseudo-continuous ASL (pCASL) as clinically implemented by GE and Philips. MATERIAL AND METHODS 22 healthy volunteers were scanned twice o...

In this paper, we consider a dual-channel vendor-buyer system consisting of a buyer and two vendor-owned facilities: a central distribution center (DC) and a regional DC. Orders for a single item are delivered through two distinct channels: an indirect channel, comprising the central DC, the regional DC and the buyer; and a direct channel, comprising the central DC and the buyer, bypassing the ...

--In this paper, we consider an integrated inventory model with one vendor and multiple retailers. In this three-tier supply chain system, the vendor purchases raw material produces into finished products, and delivers finished products to the retailers. We assume that the production (at the vendor) and the replenishment (at all the retailers) of the finished products share the common cycle tim...

This study of international information systems (IS) offshoring highlights the idea that project success or failure is often in the eye of the beholder and that proper attention needs to be provided to both client and vendor perspectives. This research contributes by identifying noteworthy IS offshoring challenges faced by client and vendor stakeholders. This research synthesizes key findings f...

We analyze the effect of buyer, contract, and vendor characteristics on abnormal stock returns among firms that have announced large scale Information Technology (IT) and Business Process outsourcing (BPO) contracts. We draw upon a comprehensive dataset on outsourcing announcements, augmented with data from public sources. Salient buyer factors examined include use of a wide range of organizati...

We investigate the effect of exploitative and exploratory learning activities on ITO vendor profitability. We present a mixed-method strategy to iteratively inform our research with an unprecedented data set of both qualitative and quantitative data on projects of the ERP service vendor OMEGA. In this paper, we report on initial quantitative findings, which show that exploitative activities hav...

Abstract Prior studies show that coordinating supply chain inventories with common replenishment epochs (CRE) provides benefit for vendor and buyers. Coordination using selective discount (SD) strategy allows some buyers to participate in the coordination scheme while other buyers continue to order as earlier. This can reduce the vendor’s total cost more than that of all buyers participating an...
