T paper develops a framework for measuring “tipping”—the increase in a firm’s market share dominance caused by indirect network effects. Our measure compares the expected concentration in a market to the hypothetical expected concentration that would arise in the absence of indirect network effects. In practice, this measure requires a model that can predict the counterfactual market concentrat...

This paper examines strategies of standard software vendors, in view of the existence of network effects on standard software markets. In particular, we analyze if and under which conditions penetration pricing can be considered as a promising strategy. Our work is based on a simulation model, which provides the opportunity to examine the impact of alternative pricing strategies on the distribu...

www.onk.ns.ac.rs/Archive Vol 21, No. 3-4, December 2013 INTRODUCTION Cervical carcinoma represents one of the major problems in developing countries where the cervical population-screening program is still not developed (1). Approximately 45% of surgically treated stage IB cancers occur in women under the age of 40 years (2). However, in developed countries, screening enables the detection of c...

BACKGROUND Free jejunal transfer has become the standard technique for reconstruction of the pharynx and hypopharynx, especially with proximal neoplastic lesions, whereas gastric tube interposition is the technique of choice for reconstruction of the hypopharynx and cervical esophagus when resection extends below the thoracic inlet. HYPOTHESIS Surgical ablation is a viable option for advanced...

Conventional drilling of rock, in most mining applications, uses the mechanical impact of a metal tool to create the advancing hole. This technique, which has gradually increased in power and thus penetration rate has, however, certain inherent disadvantages. These range from the overall weight of the equipment which must be located at the free face of the hole to the maintenance of alignment o...

In this study, we explore the global effect of the Internet on democracy over the period of 1992 to 2002 by observing the relationships between measures related to democracy and Internet prevalence. Our findings suggest that while Internet usage was not a very powerful predictor of democracy when examining full panel data from 1992 to 2002, it was a stronger predictor when we study data from ju...

The need for a drying stress indicator has previously been stated with some research in the past to this means. Given the recent successes in achieving this goal through monitoring shrinkage, the refinement and further understanding of the process was needed, specifically, the influence that penetration of the mount-foot had on the shrinkage data. Four different LVDTmounts were investigated in ...
