    A hybrid computer solution of the swing equation

    Get PDF
    Models for the governor and exciter control systems are presented and the development of a hybrid computing system including these models is described. A technique for including the governor and exciter effects into the solution of the power system swing equation is also discussed. A hybrid computing system consisting of an SCC 650 digital computer, hybrid interface, and an EAI-TR-48 analog computer is used to study five test cases. The test cases involve basically the same example system with different values for fault clearing times and machine inertias. The results of each test case are briefly discussed with relevance to the importance of the inclusion of the control system effects. The advantages and disadvantages of a hybrid computing system are also discussed --Abstract, page ii

    Fatigue and Crack-Growth in 7050-T7451 Aluminum Alloy under Constant- and Variable-Amplitude Loading

    Fatigue and crack-growth tests were conducted on 7050-T7451 aluminum alloy under a wide range of loading conditions. Crack-growth tests were conducted on compact, C(T), specimens under constant-amplitude loading, single-spike overloads, and a simulated aircraft spectrum loading. Fatigue tests were also conducted on single-edge-notch bend, SEN(B), specimens under constant-amplitude loading and three aircraft load spectra. The FASTRAN, life-prediction code, was used to make crack-growth predictions on the C(T) specimens; and to make fatigue-life calculations using a 12-micrometer initial flaw size at the center of the edge-notch on the SEN(B) specimens. The predictions agreed fairly well with most of the tests, except the model was unconservative on the single-spike overload tests and the severe spectrum Mini-TWIST+ Level 1 tests. The discrepancy was suspected to be caused by a low constraint factor and/or crack paths meandering around overload plastic zones. A roughness- and plasticity-induced crack-closure model would be needed to improve the model

    The Impact of the Repeal of the Stock-for-Debt Exception on Corporate Bankruptcy Restructurings

    This paper investigates the effect repeal of the stock-for-debt exception on corporate bankruptcy restructurings. This exception permitted corporations to exclude cancellation of indebtedness income from gross income provided they exchanged their own common equity for debt while in Chapter 11. Consistent with claims made by Easton (1994), it is found that the change in tax law imposed significant explicit tax costs on bankruptcy filers. Despite these costs, it is found that many of these firms altered their debt restructure method to preserve net operating losses and reduce their cost of equity. Almost half of the sample firms issued significant levels of debt while in Chapter 11. Additionally, approximately a third of these firms responded to the change in tax law to preserve NOLs by electing an alternative provision available under the ownership change rule bankruptcy exception that allows for a one-time reduction in NOL tax attributes. It is also shown that the remaining firms were precluded from changing their debt restructure method, despite the loss of all of their NOL tax attributes, because the financial reporting marginal costs of doing so exceeded any marginal tax benefits that might have been generated

    Discontinued Operations Recognition, Initial Provisions, And Subsequent Adjustments

    This study extends our understanding of why firms choose to take discretionary write-offs and identifies factors that influence the measurement of the charges taken. We focus on segment disposals, initial provisions recorded upon discontinuance of those segments, and adjustments to initial provisions that accompany the segment disposals. We partition our sample into those disposals that were substantially completed at the time of recognition (nondiscretionary disposals) and those that were recognized prior to disposal completion (discretionary disposals). With respect to motivations for taking discretionary rather than nondiscretionary disposals, we find that firms electing discretionary disposals discontinue segments that experience sharp declines in earnings and that require more negative initial provisions; the continuing portion of these firms are less profitable and are in weaker financial condition when compared to firms recognizing disposals upon completion. Further, they are more likely to announce the disposal in the fourth quarter, and they are more likely to underestimate the cost of disposal. With respect to measurement issues, we find that subsequent adjustments to initial provisions for discretionary disposals relate both to firms’ abilities to estimate losses on disposal at the plan date and to management incentives to manage disclosures. In contrast, subsequent adjustments accompanying nondiscretionary disposals relate primarily to uncertainties contained in the disposal agreement

    Auditor-provided Tax Services and Clients’ Tax Avoidance: Do Auditors Draw a Line in the Sand for Tax Advisory Services?

    Get PDF
    In this study, we empirically examine the upper bound of the relationship between auditor-provided tax services (APTS) and clients’ level of tax avoidance. This question is of significant interests for regulators because recent incidents of audit firms’ involvement in clients’ tax aggressive activities have reignited concerns about the extent to which non-audit services could impair auditor independence and audit quality. Using quadratic and linear-log regressions, we document a negative association between tax fees paid and clients’ effective tax rates, but the association diminishes as clients become more tax aggressive. Interestingly, using quartile regressions, we find evidence that for the most tax aggressive firms (firms in the lowest quartile of ETR), the association between APTS and ETR turns positive. This positive association is consistent with audit firms reducing their level of tax service engagement when clients become more tax aggressive, possibly due to regulatory, reputational, or litigation concerns. These results are consistent with audit firms adhering to PCAOB’s Rule 3522, which prohibits the provision of tax aggressive services to public clients. In cross-sectional analyses, we find some evidence that large clients influence audit firms to be more tax aggressive, consistent with economic bonding between these parties. These results should be informative to policymakers and regulators in their review of non-audit services

    Valuation and Classification of Company Issued Cash and Share-Puts

    Get PDF
    This paper examines whether investors’ valuations of cash and share-put warrants are influenced by their potential differential effect on firm solvency. It is motivated by the enactment of SFAS 150, which requires that all contingent put warrant obligations be classified as balance sheet liabilities regardless of put type. Consistent with the critics of SFAS150, we show that market participants differentially value cash and share-puts based on their solvency characteristics beyond the firm’s recorded assets and liabilities. Our results add to existing capital structure literature by suggesting that complex financial instruments (such as cash and share-puts) be reported separately from each other on a firm’s balance sheet

    The neighbourhood environment and profiles of the metabolic syndrome

    Get PDF
    Background: There is a dearth of studies on how neighbourhood environmental attributes relate to the metabolic syndrome (MetS) and profiles of MetS components. We examined the associations of interrelated aspects of the neighbourhood environment, including air pollution, with MetS status and profiles of MetS components. Methods: We used socio-demographic and MetS-related data from 3681 urban adults who participated in the 3rd wave of the Australian Diabetes, Obesity and Lifestyle Study. Neighbourhood environmental attributes included area socio-economic status (SES), population density, street intersection density, non-commercial land use mix, percentages of commercial land, parkland and blue space. Annual average concentrations of NO2 and PM2.5 were estimated using satellite-based land-use regression models. Latent class analysis (LCA) identified homogenous groups (latent classes) of participants based on MetS components data. Participants were then classified into five metabolic profiles according to their MetS-components latent class and MetS status. Generalised additive mixed models were used to estimate relationships of environmental attributes with MetS status and metabolic profiles. Results: LCA yielded three latent classes, one including only participants without MetS ("Lower probability of MetS components" profile). The other two classes/profiles, consisting of participants with and without MetS, were "Medium-to-high probability of high fasting blood glucose, waist circumference and blood pressure" and "Higher probability of MetS components". Area SES was the only significant predictor of MetS status: participants from high SES areas were less likely to have MetS. Area SES, percentage of commercial land and NO2 were associated with the odds of membership to healthier metabolic profiles without MetS, while annual average concentration of PM2.5 was associated with unhealthier metabolic profiles with MetS. Conclusions: This study supports the utility of operationalising MetS as a combination of latent classes of MetS components and MetS status in studies of environmental correlates. Higher socio-economic advantage, good access to commercial services and low air pollution levels appear to independently contribute to different facets of metabolic health. Future research needs to consider conducting longitudinal studies using fine-grained environmental measures that more accurately characterise the neighbourhood environment in relation to behaviours or other mechanisms related to MetS and its components

    Impact of Age and Estimated Glomerular Filtration Rate on the Glycemic Efficacy and Safety of Canagliflozin: A Pooled Analysis of Clinical Studies.

    AbstractObjectiveReduced efficacy has been reported in the elderly; it may be a consequence of an age-dependent decline in estimated glomerular filtration rate (eGFR) rather than ageing per se. We sought to determine the impact of these 2 parameters, as well as sex and baseline body mass index (BMI), on the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in people with type 2 diabetes.MethodsData were pooled from 6 randomized, double-blind, placebo-controlled studies (18 or 26 weeks; N=4053). Changes in glycated hemoglobin (A1C) and systolic blood pressure (BP) from baseline with canagliflozin 100 mg and 300 mg and placebo were evaluated in subgroups by sex, baseline BMI, baseline age and baseline eGFR. Safety was assessed by reports of adverse events.ResultsPlacebo-subtracted reductions in A1C with canagliflozin 100 mg and 300 mg were similar in men and women. A1C reductions with canagliflozin were seen across BMI subgroups and in participants aged <65 years and ≄65 years. Significantly greater placebo-subtracted reductions in A1C were seen with both canagliflozin doses in participants with higher baseline eGFR (≄90 mL/min/1.73 m2). Reductions in systolic BP were seen with canagliflozin across subgroups of sex, BMI, age and eGFR. A1C reductions with canagliflozin were similar for participants aged <65 or ≄65 years who had baseline eGFR ≄60 mL/min/1.73 m2 and were smaller in older than in younger participants with baseline eGFR 45 to <60 mL/min/1.73 m2. The overall incidence of adverse events was similar across treatment groups regardless of sex, baseline BMI, baseline age or baseline eGFR.ConclusionsCanagliflozin improved glycemic control, reduced BP and was generally well tolerated in people with type 2 diabetes across a range of ages, BMIs and renal functions

    The group purchasing process : an investigation into the influence of the facilitator in alpine tourism

    Full text link
    Group travel is a common feature of all tourism markets and can vary from the familiar peer group/common purpose associations of the football and cricket followers to the non-familiar co-operative travel group of the under 35 year olds bus adventures throughout Europe. This study investigates the nature of social group travel in alpine tourism. It specifically examines the phenomena of the &quot;group facilitator&quot;; the person within the group who takes a major role in the travel decisions and organisation on rehalf of all the other members in the travel party. The specific activities of this &quot;group facilitator&quot; and the role of opinion leadership, information search, organisation process, previous experience, relationship ties between the group members are examined. The \u27facilitator\u27 also influences other individuals\u27 decision to participate who delegate selection of destination to this person as well. The \u27facilitator\u27 has many of the characteristics of an opinion leader and was recognised by group participants as a major source of information about the destination. The findings of the study have important implications for tourism marketers as they highlight an opportunity to reach many potential travellers by directly targeting one key influencer and decision maker.<br /
