    Notizen: To compare direct tests for detecting determinism in chaotic time series, data from Hénon, Lorenz, and Mackey–Glass equations were contaminated with various levels of additive colored noise. These data were analyzed with a variety of recently developed tests for determinism, and the results compared. © 1995 American Institute of Physics.

    Notizen: We present grazing-incidence measurements of polarized electroabsorption spectra in p–i–n solar cells based on hydrogenated amorphous silicon (a-Si:H). We find a significantly stronger polarization dependence in the present measurements compared with earlier work based on electroabsorption detected using coplanar electrodes on a-Si:H thin films. We do not find any significant dependence of the polarized electroabsorption upon light soaking, although this effect was found in previous work with coplanar electrodes. © 1998 American Institute of Physics.

    Notizen: We present a technique for using modulated electroabsorption measurements to determine the built-in potential in semiconductor heterojunction devices. The technique exploits a simple relationship between the second-harmonic electroabsorption signal and the capacitance of such devices. We apply this technique to hydrogenated amorphous silicon (a-Si:H)-based solar cells incorporating microcrystalline Si p+ layers. For one set of cells with a conventional plasma-deposited intrinsic (i) layer we obtain a built-in potential of 0.98±0.04 V; for cells with an i layer deposited using strong hydrogen dilution we obtain 1.25±0.04 V. We speculate that interface dipoles between the p+ and i layers significantly influence the built-in potential. © 1996 American Institute of Physics.

    Notizen: Objective To determine the safety and efficacy of intramuscular oxytocin plus ergometrine compared to intravenous oxytocin for prevention of postpartum haemorrhage, and the significance of administration at the end of the second stage of labour compared with that after the third stage.Design A prospective cohort study.Setting A university affiliated tertiary medical centre.Participants Two thousand one hundred and eighty–nine women delivering singletons during 40 consecutive weeks.Main outcome measures Postpartum haemorrhage (〉 500 ml), prolonged third stage (〉 30 min), retained placenta (〉60min), elevated blood pressure (systolic 〉 150 mmHg, diastolic 〉 100 mmHg).Results The rate of postpartum haemorrhage was not significantly different for oxytocinergometrine compared with oxytocin, when administered at the end of the second stage of labour (odds ratio 1.10, 95% confidence interval (CI) 0.75–1.61) or after the third stage (odds ratio 0.95, 95% CI 0.68–1.34). The patients receiving oxytocics at the end of the second stage of labour had significantly lower rates of postparturn haemorrhage, for both oxytocinergometrine (odds ratio 0.69, 95% CI 0.49–0.98) and oxytocin (odds ratio 0.60, 95% CI 0.41–0.87), compared with those treated after the third stage.Conclusion Administration of oxytocin alone is as effective as the use of oxytocin plus ergometrine in the prevention of postpartum haemorrhage, but associated with a significantly lower rate of unpleasant maternal side effects. Oxytocics administered after delivery of the fetal head compared with after the placental expulsion are associated with a significantly lower rate of postpartum haemorrhage.

    Notizen: In 1974, the Securities and Exchange Commission (SEC) noted that an increasing number of companies were capitalizing interest costs, and that this practice was not being adequately disclosed (FASB, 1979, par. 26). In light of the alternative practices concerning the accounting for interest and lack of adequate disclosure by companies that were already capitalizing interest, the SEC recommended that the Financial Accounting Standards Board (FASB) consider the issue of accounting for interest cost. As a result of the SEC's initiative, in 1979 the FASB issued Statement of Financial Accounting Standards [SFAS] No. 34, Capitalization of Interest Cost, which mandated uniform interest capitalization rules in accounting for interest costs associated with the acquisition of qualifying non-current assets.The purpose of this article is to examine SFAS 34 in terms of its financial statement impact, the congruence of its assumptions with economic behaviour, its effect on subsequent standards related to interest capitalization, and its implications on financial accounting standard setting.To explore these issues we first illustrate the extent to which interest capitalization affects financial statements. We then empirically analyse the measure employed in SFAS 34 for the capitalization of interest cost in cases where debt is not directly linked with the acquisition of qualifying non-current assets. In addition, we critically examine the treatment accorded interest cost in subsequent FASB standards. Our research suggests that SFAS 34′s rationale for interest capitalization is incompatible with firm behaviour, and that the rules for interest capitalization as reflected in various accounting standards are inconsistent. These findings suggest that in the case of interest capitalization the benefits of comparability in financial reporting are not realized. A policy recommendation is then offered to alleviate some of these difficulties. The recommendation is to disallow the capitalization of interest cost in the absence of a direct link between the debt and the acquisition of qualifying assets.

    Notizen: : Background: Adequate prenatal care is important for ensuring a good outcome for pregnant women and their children, and its initiation in the first trimester is a major component. We investigated barriers and motivators for women receiving early versus late prenatal care. Methods: A self-administered questionnaire was distributed to 205 women who began prenatal care at the University of New Mexico Hospital Obstetrics Clinic in Albuquerque, New Mexico. The questionnaire assessed demographic information, insurance status, feelings about the pregnancy, health behaviors, and barriers and motivators to initiating prenatal care. The participants were Hispanic (41%) and non-Hispanic white (46%), low-income women with Medicaid (42%) or no health insurance (41%). They were divided into early (1st trimester 67%) and late (after 1st trimester 33%) care groups. Results: Ethnicity, education, income, and age did not predict initiation of prenatal care. Late initiators cited financial problems (26%), not being aware of the pregnancy (15%), and dislike of going to doctors (14%) as reasons for the delay in seeking prenatal care. Over two-thirds of the pregnancies were unplanned, but 82 percent of the women felt positive about the pregnancy. Conclusions: Our study documents the continuing need for public health efforts to encourage women to seek early prenatal care. Specific attention should be directed toward women's perceived reasons for not initiating early care.
