This paper constructs a structural model of title-specific saturation in demand that controls for a shrinking consumer base. The estimates of the partial reduced form of this model show that saturation is a significant phenomenon in theatrical exhibition of the domestic motion picture industry, while the estimates of the structural...
This paper considers theory and evidence from the domestic theatrical movie industry regarding biases in estimation that arise when saturation in demand is ignored or approximated with a product's age. The underlying structural model and resulting partial reduced form model can both be readily generalized for other applications. Results indicate...
From its beginning in 1998, New Dominion, L.L.C. NDL has been focused on producing high-water-saturation reservoirs, such as the Hunton limestone in central Oklahoma. Wells in this environment had been conventionally produced and typically abandoned, or bypassed entirely, because of high water production and the economic factors associated with the...
Despite interest in measurement of central venous oxygen saturation (ScvO2), there are no published data describing the pattern of ScvO2 changes after major general surgery or any relationship with outcome. The paper depicts that significant fluctuations in ScvO2 occur in the immediate post-operative period. These fluctuations are not always associated...
Measuring arterial oxygen saturation with pulse oximetry is an integral component of the Sleep Laboratory evaluation for Sleep-Disordered Breathing. Indeed, in a recent Position Paper, the American Academy of Sleep Medicine AASM proposed new criteria for the diagnosis of hypopnea in adult patients. Due to these new guidelines, and an...
The kinetics of calcium sulfate dihydrate spontaneous precipitation in super saturation solutions for temperatures ranging between 20 and 70°C was investigated. The quartz microbalance technique QMC was used. From measurements of the induction period for gypsum nucleation, interfacial tension was found to be 48.5 and 46.2 mJ.m² at 20 and...
Hypothermia causes peripheral hypoperfusion, which, if sustained, produces localized hypoxemia. Sustained low perfusion increases the arterial-venous O2 difference so that with motion the detection of pulsating non-arterial blood produces pulse peaks that do not correspond with arterial saturation and are entered into the display of SpO2. The lower and more...
Monitoring arterial oxygen saturation with pulse oximetry has become standard of care in the Operating Room OR and Post Anesthesia Care Unit PACU. Patient movement occurs frequently in the PACU and in the OR, especially during pediatric induction and emergence. Conventional pulse oximeters do not perform well in motion especially...
During a prospective study of the impact of improved oximetry on clinical practice, the researchers found that caregivers more rapidly weaned cardiac surgery patients from a high FiO2 while obtaining fewer ABGs, when the clinicians had access to data from a Masimo SET oximeter. The MSO had a smaller bias...
Chris Krasowski submits: The deal, which is reported to be valued at $28.1 Billion certainly isn't a drop in the bucket for Verizon VZ, but it does show just how aggressive the mobile space will be in the years to come. With an estimated 3 Billion people with...
The paper mentions that by-passed hydrocarbons are best located using a variety of reservoir characterization techniques and technologies. Well-defined petrophysical properties are fundamental to understanding fluid saturation and distribution in reservoirs. New techniques such as Moving Domain and recent advances in accurate 3-D geologic modeling and nonparametric statistics can significantly...
Cellular mobile will remain the dominant mobile and wireless technology in 2005. By the end of the year, there will be nearly 2 billion subscriptions worldwide. The report depicts that as the mobile market approaches saturation, segmentation strategies will become far more important and sophisticated. Services and pricing will increasingly...
The product life cycle has been part of marketing strategy since the late 50's. People are either intuitively or intellectually aware of its five stages of introduction, growth, maturity, saturation and decline. Yet, this classic model now faces the same inevitability it predicted for brands and market segments. Everyone faces...
During cardiopulmonary bypass CPB, oxygenation is often only intermittently monitored via arterial blood gas analysis ABG. CPB may not generate sufficient pulsations for pulse oximetry to work continuously. These researchers studied the use of external oscillations to produce accurate SpO2 measurements during CPB. Sampling of ABG every 30 minutes is...
The article highlights that while many providers of broadband access have fallen on hard timesùDirecTV in the United States is only the latest to exit the businessùbroadband itself is gaining popularity. As broadband moves into the mainstream, it is reshaping the telecommunications, cable, and Internet access industries. So far, there...
The momentum of information technology IT advancement defines the way society operates. The healthcare industry has been a wary adopter of technology. But, the healthcare industry's medical and regulatory complexity and the financial burden associated with IT have precluded the rapid saturation of integrated technology solutions into hospital operations. The...
Companies in the telecommunications industry face a number of challenges as market saturation, slow uptake of new services, and the economic downturn increase pressures to cut costs and improve efficiency. Industry deregulation has led to intense competition and rising customer expectations. To succeed in this environment, telecommunications companies require solutions...
In their pursuit of customer revenues, wireless operators have become "accidental retailers," building networks of single-brand, single-product stores that collectively cover over 6,000 locations in the U.S. alone. Despite some signs of saturation, operators in the U.S. have continued to add stores - primarily driven by the expectation that company...
Every day retailers are confronted with new challenges to face in this changing world. From industry consolidation and retrenchment, new competitive threats and a slowing economy, retailers are forced to rethink how they run their operations to maximize shareholder value. Within this climate of market saturation, a retailer's internal weaknesses...
The paper reveals that wireline logging tools have come a long way since the original spontaneous potential and resistivity tools became available decades ago. Today wireline logging tools provide basic reservoir data to operators and play a fundamental role in determining stratigraphic correlations, lithology, wellbore conditions, fluid type and saturation,...
