This research examines the duration effect and interaction effect of advertising and performance in the mutual fund industry. And we examine these effects by using the method of ordinary least squares to know how advertising and performance influence the fund investors¡¦ investment strategies. Our empirical study of the mutual fund industry shows that there is a duration effect between advertising and fund inflows, and this effect lags two periods. We also find that the interaction effect of advertising and performance is significant, with no significant effect for advertising. This result refers that there is a complement relationship between advertising and performance. Furthermore, it indicates that advertising likes a catalyst to convey the information about fund performance in attracting investors, and the performance is a major factor to construct advertising reliability.

In this paper, we propose a novel thin film MOSFET with source/drain tie and discontinuously block oxide layers. Improving process is very important, when the gate length of SOI MOSFET is reduced. To overcome the misalignment problem, we use self-aligned technology to fabricate this device. In addition, the device has discontinuously block oxide layers; they can improve short channel effects, reduce the parasitic capacitance, and decrease the leakage current cause by P-N junction between source/drain and body regions. They also supply two pass ways to eliminate carriers and heat which generated by impact ionization resulting in suppression of floating-body effect and self-heating effect. In addition, these two pass ways can be seen as the parallel equivalent resistance results in a reduced series resistance and an increased drain saturation current. According to the ISE TCAD 10.0 simulation results, the discontinuously block oxide layers can not only improve the short channel effects, but also eliminate the floating-body effect and diminish the self-heating effect because of the pass ways.

The work in this dissertation aims to describe a simple new test for odor-recognition memory in rats that can be readily performed and results in an easily observable and lasting form of memory. This test has allowed for the demonstration of ethanol-induced retrograde memory impairments in rats when ethanol is administered during both the consolidation and reconsolidation phases of memory encoding. The observation that a high-dose of ethanol can cause retrograde memory impairments when administered immediately or within hours after learning has taken place is an original finding that may have implications for understanding human blackouts. Furthermore, the finding that ethanol can disrupt the reconsolidation of a previously consolidated memory has not been previously established. It is also demonstrated that caffeine can prevent ethanol’s memory impairing effects, a result that contributes a new piece of evidence for caffeine’s effects on the learning and memory process. This effect has been further investigated mechanistically and attributed to caffeine’s dual role as a phosphodiesterase type 5 inhibitor and adenosine A2A antagonist. Neither of these mechanisms alone appear to be sufficient enough to prevent the retrograde memory impairments seen with ethanol. It is hoped that this test and our findings will prove useful for future investigations into the effects of ethanol on learning and memory and the human phenomenon of alcohol-induced blackouts. / text

Part I. In order to determine the effect of dose size on the bioavailability of phenytoin (Dilantinᴿ), a single intravenous dose of 15 mg/kg, single oral doses of 400, 800, 1600 mg, and 1600 mg in divided doses (i.e. 400 mg every three hours) were administered to six healthy male subjects. Values of V(max) and K(m) obtained from the intravenous dose were used to determine the extent of absorption from the oral doses. Although no statistically significant difference in extent of phenytoin absorption was observed, the time to reach maximum phenytoin serum concentrations increased significantly from 8.4 hours for the 400 mg dose and 13.2 hours for the 800 mg dose to 31.5 hours for the 1600 mg dose. Peak serum concentrations of 3.9, 5.7, 10.7, and 15.3 mg/1 were observed after the 400, 800, 1600 and 1600 mg divided doses, respectively. It is suggested that the prolonged, but complete, absorption of large phenytoin doses is due to a slow dissolution and continued absorption from the colon. Owing to the prolonged absorption of phenytoin, it may be necessary to use a larger oral than intravenous loading dose to produce similar maximum phenytoin serum concentrations. Part II. The effects of age and obesity on the pharmacokinetics of thiopental were studied in 7 morbidly obese (aged 25 to 46 years) and 22 lean patients (aged 25 to 83 years), who were primarily undergoing abdominal surgery. In all 29 patients, serum thiopental concentrations were determined by gas-liquid chromatography using a nitrogen-selective detector. Based upon total (bound+free) thiopental concentrations, the average (±S.E.) volumes of distribution (Vᵦ and V(ss)) were significantly larger in the obese (7.94 ± 1.72 1/kg and 4.72 ± 1.03 1/kg, respectively) than in the age-matched lean patients (1.95 ± 0.22 1/kg and 1.40 ± 0.16 1/kg, respectively). Clearance based on total thiopental concentrations normalized to total body weight (TBW) was not significantly different between the obese (0.18 ± 0.03 1/hr/kg) and lean patients (0.21 ± 0.02 1/hr/kg). However, total body clearance not normalized to TBW was significantly larger in the obese (24.98 ± 5.62 1/hr) than in the lean patients (11.86 ± 1.29 1/hr). The half-life of thiopental was significantly larger in the obese (31.87 ± 4.53 hours) than in the lean patients (6.61 ± 0.52 hours) and was primarily a function of the larger apparent volume of distribution for thiopental. The unbound fraction of thiopental in serum (range, 17.8% to 27.6%) did not depend on the degree of obesity, but was found to be greater with advancing age. The apparent volumes of distribution, Vᵦ and V(ss), were also related to age. No significant relationship was found between total body clearance with increasing age. Thus, the half-life of thiopental was positively correlated with age, and as in the obese study, was found to be primarily influenced by the apparent volume of distribution.
