    Literature Review and suggested protocol for managing ultrasound soft markers for Down syndrome: Thickened nuchal fold, echogenic bowel, shortened femur, shortened humerus, pyelectasis and absent or hypoplastic nasal bone

    JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2007
    Article first published online: 10 MAY 200, M Bethune
    Summary Mid-trimester soft markers have been linked with Down syndrome and other aneuploidies. There are many other prenatal screening tests available with better detection rates for Down syndrome than the mid-trimester ultrasound. Many patients confronted with the diagnosis of a soft marker become anxious and may request a diagnostic test (amniocentesis) despite the associated risk of miscarriage. This is also despite the fact that most fetuses with an isolated soft marker are chromosomally normal. The management of a pregnancy with a soft marker must therefore be planned in a manner designed to minimize patient anxiety. Likelihood ratios can be used to modify a patient's ,prior risk' (based on age or prior screening tests) and create a new risk. This calculation may help identify a subset of patients suitable for further investigation. It has been proposed that ,negative' likelihood ratios can be used to reduce a patient's risk if no soft marker is found at a mid-trimester ultrasound. There remain concerns about this approach and further research is required before this approach enters common practice. The published work surrounding the management of thickened nuchal fold, echogenic bowel, shortened femur, shortened humerus, pyelectasis (renal pelvis dilatation) and hypoplastic nasal bone is reviewed. Each soft marker has different associations and individual management plans for each of these soft markers are presented. Although isolated single umbilical artery is not usually considered a soft marker of aneuploidy, a management plan for this common finding is also included. [source]

    Optimal timing to invest in e-commerce

    PSYCHOLOGY & MARKETING, Issue 4 2006
    Jow-Ran Chang
    The timing of investment in e-commerce remains hotly debated in both the academic and investment communities. This study develops a framework for analyzing the optimal timing for a company to invest in e-commerce for conducting its business-to-business (B2B) or business-to-consumer (B2C) transactions. This study applies a real option theory to assess a new risk,reward dynamic for investing in e-commerce. The numerical results demonstrate that the optimal timing of investment in e-commerce depends on uncertainties regarding future cash flows and the opportunity costs associated with e-commerce. Implications with regard to the behavior of Internet companies from a financial perspective are discussed. © 2006 Wiley Periodicals, Inc. [source]

    Minimum variance cross hedging under mean-reverting spreads, stochastic convenience yields, and jumps: Application to the airline industry

    THE JOURNAL OF FUTURES MARKETS, Issue 8 2009
    Mark Bertus
    Exchange traded futures contracts often are not written on the specific asset that is a source of risk to a firm. The firm may attempt to manage this risk using futures contracts written on a related asset. This cross hedge exposes the firm to a new risk, the spread between the asset underlying the futures contract and the asset that the firm wants to hedge. Using the specific case of the airline industry as motivation, we derive the minimum variance cross hedge assuming a two-factor diffusion model for the underlying asset and a stochastic, mean-reverting spread. The result is a time-varying hedge ratio that can be applied to any hedging horizon. We also consider the effect of jumps in the underlying asset. We use simulations and empirical tests of crude oil, jet fuel cross hedges to demonstrate the hedging effectiveness of the model. © 2009 Wiley Periodicals, Inc.

    Greece: How can companies manage the new risks?

    JOURNAL OF CORPORATE ACCOUNTING & FINANCE, Issue 6 2010
    Bento J. Lobo
    CEOs and CFOs must understand that political risk can have a significant impact on a company's profitability. The current situation in Greece is a prime example of this. But how does the risk of Greece's default affect U.S. firms doing business with Greek companies? The authors examine the impact on two kinds of U.S. firms: those exporting to Greece and those importing from Greece. The authors then look at ways to manage the impact of sovereign risk of default. © 2010 Wiley Periodicals, Inc. [source]

    Handling Weather Related Risks Through the Financial Markets: Considerations of Credit Risk, Basis Risk, and Hedging

    JOURNAL OF RISK AND INSURANCE, Issue 2 2007
    Linda L. Golden
    The profits of many businesses are strongly affected by weather related events, and insurance against weather related risks (acts of God) has been a traditional domain for transfer of (certain) of these risks. Recent innovations in the capital market have now provided financial instruments to transfer and hedge some of these risks. Unlike insurance solutions, however, using these financial derivative instruments creates a situation in which the return to the purchaser of the instrument is no longer perfectly correlated with the loss experienced. Such a mismatch creates new risks which must be examined and evaluated as part of ascertaining cost effective risk management plans. Two newly engendered risks, basis risk (the risk created by the fact that the return from the financial derivative is a function of weather at a prespecified geographical location which may not be identical to the location of the firm) and credit risk (the risk that the counterparty to the derivative contract may not perform), are analyzed in this article. Using custom tailored derivatives from the over the counter market can decrease basis risk, but increases credit risk. Using standardized exchange traded derivatives decreases credit risk but increases basis risk. Here also the effectiveness of using hedging methods involving forwards and futures having linear payoffs (linear hedging) and methods using derivatives having nonlinear payoffs such as those involving options (nonlinear hedging) for the purpose of hedging basis risk are examined jointly with credit risk.

    A Global Review of New Social Risks and Responses for Children and their Families

    ASIAN SOCIAL WORK AND POLICY REVIEW, Issue 1 2009
    Shirley Gatenio Gabel
    Given global demographic and social trends, the need for new policy and program responses is essential. This article identifies and describes new and traditional social risks affecting children and their families in both industrialized and developing countries by region. Traditional risks continue in the developing as well as the industrialized countries but the extent and scale are very different and the problems are far more severe in developing countries. In addition, new risks are now evident and new policy responses are emerging. Attention to the new risks is increasing, with growing investment in services and policies facilitating the reconciliation of work and family life and non-traditional families. The citizens of many developing countries experience new risks as well, but their capacity to confront and address these risks is also more limited. [source]

    Guidance on Safety/Health for Process Intensification Including MS Design.

    CHEMICAL ENGINEERING & TECHNOLOGY (CET), Issue 3 2010
    III: Risk Analysis
    Abstract The new technology of process intensification by multiscale equipment can significantly contribute to achieve a safer design by going from batch/semi-batch to continuous operation combined with a reduction of inventory of hazardous substances in critical stages. On the other hand, the shift to higher space-time-yields comprises new risks such as runaway reactions with hot spot formation, described in Part,I, and handling an explosive atmosphere in the presence of potential permanent ignition sources, described in Part,II. A tool was developed for preliminary risk assessments, called HAZOP-LIKE study, to cover the characteristic features of micro-designed equipment that are relatively unimportant when handling conventional equipment. Two generic cases concerning liquid/liquid and gas/gas reactions were studied to demonstrate the method. [source]

    Guidance on Safety/Health for Process Intensification including MS Design; Part I: Reaction Hazards

    CHEMICAL ENGINEERING & TECHNOLOGY (CET), Issue 11 2009
    O. Klais
    Abstract The implementation of process intensification by multiscale equipment will have a profound impact on the way chemicals are produced. The shift to higher space-time yields, higher temperatures, and a confined reaction volume comprises new risks, such as runaway reactions, decomposition, and incomplete conversion of reactants. Simplified spreadsheet calculations enable an estimation of the expected temperature profiles, conversion rates, and consequences of potential malfunction based on the reaction kinetics. The analysis illustrates that the range of optimal reaction conditions is almost congruent with the danger of an uncontrolled reaction. The risk of a spontaneous reaction with hot spots can be presumed if strong exothermic reactions are carried out in micro-designed reactors. At worst, decomposition follows the runaway reaction with the release of noncondensable gases. Calculations prove that a microreactor is not at risk in terms of overpressure as long as at least one end of the reactor is not blocked. [source]

    Changing Definitions of Risk and Responsibility in French Political Scandals

    JOURNAL OF LAW AND SOCIETY, Issue 3 2002
    Violaine Roussel
    In the 1990s in France, a large number of political scandals developed and many political actors were prosecuted. This process of making politicians responsible related, in particular, to the rise of ,new risks' regarding public health and security. In this paper, I analyse the diffusion and the crystallization of discourses linking public risk and political responsibility. First, I point to some of the social and cognitive bases in which the recent uses of the notions of risk and responsibility are rooted. Second, I focus on the mechanisms through which the notions were mobilized and invested with new definitions in the course of the scandal hearings. Third, I explore some of the effects of the changes which occurred during the 1990s: new perception frames in terms of risk and responsibility are consolidated and are progressively appropriated by social actors located in various professional spheres.
