This paper studies the impact of competition on a firm's choice of technology (product-flexible or product-dedicated) and capacity investment decisions. Specifically, we model two firms competing with each other in two markets characterized by price-dependent and uncertain demand. The firms make three decisions in the following sequence: choice of(More)
We analyze volume flexibility — the ability to produce above/below the installed capacity for a product — under endogenous pricing in a two-product setting. We discover that the value of volume flexibility is a function of demand correlation between products, an outcome which cannot be explained by classical risk-pooling arguments. Furthermore, while the(More)
The importance of material flow management for a profit-maximizing firm has been well-articulated in the supply chain literature. We demonstrate in our analytical model that a firm must also actively manage information flows within the supply chain, which translates to controlling what it knows, as well as what its competitors and suppliers know. In our(More)
Product launch – an event when a new product debuts for production in a plant – is an important phase in product development. But launches disrupt manufacturing operations resulting in productivity losses. Using data from North-American automotive plants from years 1999-2007, we estimate that a product launch entails an average productivity loss of 12-15%(More)
BACKGROUND Shoulder subluxation is a frequent occurrence in individuals following a stroke. Although various methods of treatment are available, none of them address all possible consequences of the subluxation pain, limited range of motion, the subluxation, and decreased functional use of the arm. AIMS The purpose of this study was to evaluate the(More)
Background: Neural mobilization techniques leads to facilitation of nerve gliding, reduction of nerve adherence , dispersion of noxious fluids, increased neural vascularity and improvement of axoplasmic flow. It has pronounced effects on monosynaptic H-reflex, which is an electrically induced reflex analogous to mechanically induced spinal stretch reflex.(More)
AIMS Pregnancies achieved by in vitro fertilization (IVF) are at increased risk of adverse outcome. The main objective of this study was to evaluate the predictive value of β-human chorionic gonadotrophin (β-HCG) and age of the patient for the successful outcome in IVF. MATERIALS AND METHODS A retrospective study was done in 139 pregnancies after IVF at(More)
OBJECTIVES To compare the efficacy of letrozole and clomiphene citrate (CC) in patients of anovulatory polycystic ovarian syndrome (PCOS) with infertility. MATERIALS AND METHODS This prospective randomized clinical trial included 204 patients of PCOS. 98 patients (294 cycles) received 2.5-5 mg of letrozole; 106 patients (318 cycles) received 50-100 mg of(More)
