Haptophytes are recognized as seminal players in aquatic ecosystem function. These algae are important in global carbon sequestration, form destructive harmful blooms, and given their rich fatty acid content, serve as a highly nutritive food source to a broad range of eco-cohorts. Haptophyte dominance in both fresh and marine waters is supported by the mixotrophic nature of many taxa. Despite t...
This paper investigates-on the basis of the Cont-Bouchaud model-whether a Tobin tax can stabilize foreign exchange markets. Compared to earlier studies, this paper explicitly recognizes that a transaction tax-induced reduction in market depth may increase the price responsiveness of a given order. We find that the imposition of a transaction tax may still achieve a triple dividend: (1) exchange...
Many issues that were traditionally analyzed using the Baumol-Tobin model can also be analyzed, perhaps more easily, using the Lucas (1980) cash-in-advance model where money serves both as a medium of exchange and as a store of value. This is illustrated by three examples (implications) of the Lucas model: (i) the velocity of money is time varying, volatile, and ination-dependent; (ii) transit...
چکیده شاخص توپولوژیکی یک گراف عددی است که نسبت به یکریختی گراف ها پایاست و نشان دهنده ویژگی خاصی از آن گراف است. شاخص های توپولوژیکی بسیاری وجود دارد که کاربردهای زیادی در شیمی نظری پیدا کرده اند. دسته ای از شاخص های توپولوژیکی که اخیرا مورد توجه قرار گرفته اند شاخص های extended connectivity هستند، شاخص هایی که بر اساس یالهای گراف تعریف می شوند. به عنوان مثال می توان از شاخص هندسی-عددی که با ...
To study the effectiveness of the Tobin tax, we develop a model of heterogeneous interacting agents. Traders either speculate on the basis of technical or fundamental analysis, or abstain from the market, a decision which depends on profit considerations, as well as communication between agents. Simulations generate stylized facts such as unit roots in exchange rates, fat tails for returns, or ...
36 IN A RECENT paper entitled “On the Potential of a Chemical Bonds: Possible Effects of Steroids on Home Run Production in Baseball,”1 physicist Roger Tobin develops a systematic analysis showing how performance-enhancing drugs (PEDs) taken by an already highly skilled player could produce a dramatic increase in home-run production. Tobin starts by looking statistically at home-run production ...
BACKGROUND AND OBJECTIVES The predictive index for discontinuing mechanical ventilation is a prognostic parameter. The objective of this study was to evaluate the use of the Tobin index before tracheal extubation in patients undergoing general anesthesia. METHODS Eighty patients, 40 (50%) men and 40 (50%) women undergoing cholecystectomy under general anesthesia were analyzed. The mean age of...
