This article addresses two important questions. First, do US firms investing in the Pacific Rim region earn significant excess returns? It is found that they do in fact earn small, positive abnormal ...returns for the twenty-seven-year period ending in 1998. Second, what are the transaction-, firm-, and target country-specific characteristics that contribute to these returns? Later acquisitions by US multinationals moving into new lines of business benefited from these gains. Acquisitions made in countries characterized by less restrictive tax environment open banking climates, and lower levels of target government regulation also generated positive returns.

The parents of 289 children performed bacteriuria screening with a self-administered dip-strip culture, which was inoculated, incubated and interpreted in the home. Simultaneous pour-plate ...quantitative cultures and laboratory tested dip-strip cultures were done on the same urine specimen that had been tested at home. The dip-strip culture was reliable (89 percent) in detecting significant bacteriuria with home administration and interpretation. Only 1.6 percent falsely positive results occurred in the home testing. The dip-strip home cultures are an effective way to screen or followup patients with bacteriuria.
For applications in which a thyratron must function as an accurately controlling device, rather precise grid control is required. Frequently, the desired precision of firing is obtained by applying ...peaked voltage pulses to the grid of the thyratron. Satisfactory operation of the thyratron and its associated grid-control circuit usually requires an external grid-cathode capacitance and a current-limiting grid resistance. For a given pulse shape supplied by the grid signal generator, the grid resistance and capacitance can alter materially the wave form of the voltage which appears on the grid. This paper presents, in the form of curves, an analysis of the influence of the grid-circuit components upon the grid response for several commonly used grid signal pulses. Advantages of peaked wave-form grid control are discussed, and an example is worked out to illustrate the use of the curves in evaluating the grid response to a typical signal pulse.
One of the most interesting applications of sensor networks is the localization and tracking of moving objects. The cricket location-support system (CLS), originally developed at MIT and now ...distributed by Crossbow Technologies, tracks a moving object using time-difference-of-arrival (TDOA) between radio frequency (RF) and ultrasonic signals. In this work we evaluate the ability of CLS to track people with various levels of mobility within a 2-dimensional space. The results presented here are preliminary results in a larger effort to determine whether or not CLS can be used to track people in a smart assistive technology living space
A 25-year-old man with a chronically implanted stimulating electrode placed in the region of the locus coeruleus (LC) was monitored for 5 nights in a sleep laboratory to study the role of the LC in ...sleep. Sleep patterns were compared between the 2 nights in which the stimulation was applied periodically every 90 min and the 2 nights in which no stimulation was applied. In contrast to the normal sleep patterns that occurred during the 2 nonstimulation nights, electrical stimulation of the LC produced a profound disruption of sleep and significant reductions in the total amounts of NREM sleep, REM sleep, REM sleep as a percent of total sleep (NREM + REM sleep), and total sleep. Results suggest that the LC has a role in maintaining normal sleep patterns.
Beam-target double-spin asymmetries and target single-spin asymmetries were measured for the exclusive \(\pi^+\) electroproduction reaction \(\gamma^* p \to n \pi^+\). The results were obtained from ...scattering of 6 GeV longitudinally polarized electrons off longitudinally polarized protons using the CEBAF Large Acceptance Spectrometer at Jefferson Lab. The kinematic range covered is \(1.1<W<3\) GeV and \(1<Q^2<6\) GeV\(^2\). Results were obtained for about 6000 bins in \(W\), \(Q^2\), \(\cos(\theta^*)\), and \(\phi^*\). Except at forward angles, very large target-spin asymmetries are observed over the entire \(W\) region. Reasonable agreement is found with phenomenological fits to previous data for \(W<1.6\) GeV, but very large differences are seen at higher values of \(W\). A GPD-based model is in poor agreement with the data. When combined with cross section measurements, the present results provide powerful constraints on nucleon resonance amplitudes at moderate and large values of \(Q^2\), for resonances with masses as high as 2.4 GeV.
