People with medical conditions that limit their ability to work tend to receive short-term disability benefits initially and may then move to long-term and eventually to permanent disability benefits. The progression of older workers (those aged 55 to 64) along that continuum of benefits is documented here with data from a large disability insurance company. The data show that older workers who receive short-term medical disability benefits are three times as likely as younger workers to progress to receipt of Social Security Disability Insurance (SSDI) benefits, although a slight reversal of that trend occurs as workers pass age 62. Musculoskeletal conditions are the most frequent basis of short-term disability claims among older workers, with circulatory conditions running a close second. Furthermore, although all medical conditions are more likely to lead to SSDI benefits among older workers, circulatory conditions do so most frequently. This article discusses industry standards for the management of disability claims at each level of severity. It also addresses common and emerging disability management practices that may reduce the likelihood of impaired workers developing long-term or permanent financial dependence on disability benefits programs.  相似文献

The most relevant question for any joint venture is, when does the relationship become a jointventure and not simply a price-fixing cartel? With respect to this question, this Article juxtaposes Texaco, Inc. v. Dagher, 126 S. Ct. 1276 (2006), against years of contrary precedent. In Dagher, the Court altered the seemingly settled foundation of antitrust law by changing its view on past holdings and abandoning the ancillary effects doctrine. The Article provides an outline of key holdings prior to Dagher, as well as a discussion of the issues that can arise as joint ventures are formed. Additionally, the authors examine how the decision altered the foundation of joint venture law in the United States. In particular, the Article exposes several important antitrust concerns relating to joint ventures that the Supreme Court did not address in Dagher. Perhaps the most perplexing issue of Dagher is whether the venture at issue would have survived analysis under the Federal Trade Commission's "continuum" approach.  相似文献

Pharmacogenomics, applied as an aspect of molecular autopsy, may be used as an adjunct for certifying methadone fatalities. Methadone is metabolized by cytochrome P-450 (CYP) 1A2, 3A4, and 2D6. We hypothesized that methadone toxicity may be partially due to CYP 2D6 *3, *4, and *5 variant alleles, resulting in poor drug metabolism. A retrospective analysis was performed on covariables and risk factors of 21 methadone cases from the Milwaukee County Medical Examiner's Office (1998-2000). PCR genotyping showed: one heterozygous for 2D6*3, two homozygous for 2D6*4, five heterozygous for 2D6*4, and one heterozygous for both 2D6*3 and *4. This limited number of cases showed that the prevalence of poor metabolizer was higher but not significantly different from that of a control group (n = 23) (P > 0.05, Fisher Exact Test). Thus, CYP 2D6 mutations may not yet be directly associated with methadone toxicity. However, pharmacogenomics, complementing other case findings, served as an adjunct in interpreting methadone toxicity of poor and intermediate metabolizers.  相似文献

The combination of photographs taken at two or three wavelengths at and bracketing an absorbance peak indicative of a particular compound can lead to an image with enhanced visualization of the compound. This procedure works best for compounds with absorbance bands that are narrow compared with "average" chromophores. If necessary, the photographs can be taken with different exposure times to ensure that sufficient light from the substrate is detected at all three wavelengths. The combination of images is readily performed if the images are obtained with a digital camera and are then processed using an image processing program. Best results are obtained if linear images at the peak maximum, at a slightly shorter wavelength, and at a slightly longer wavelength are used. However, acceptable results can also be obtained under many conditions if non-linear photographs are used or if only two wavelengths (one of which is at the peak maximum) are combined. These latter conditions are more achievable by many "mid-range" digital cameras. Wavelength selection can either be by controlling the illumination (e.g., by using an alternate light source) or by use of narrow bandpass filters. The technique is illustrated using blood as the target analyte, using bands of light centered at 395, 415, and 435 nm. The extension of the method to detection of blood by fluorescence quenching is also described.  相似文献

While the concept of power has always been a concern to students of political science and public administration, it has been examined only peripherally in the last few years. Recent work by McClelland has indicated that power may be a very important variable in explaining managerial behavior and organizational effectiveness. Starting with a definition of power provided by McClelland, this paper develops a conceptual framework for analyzing power-related behavior in an organizational setting. The framework is then applied to a problem area of particular interest to the authors--the question of whether or not women managers can be expected to behave differently than their male counterparts because of possible differences in their orientations toward power. We conclude that differences in power needs will not impede the effectiveness of female managers, but women may be at a disadvantage in the work environment due to possible differences in the way they express these needs.  相似文献

Why do people practice citizenship in a partisan rather than in a deliberative fashion? We argue that they are not intractably disposed to one type of citizenship, but instead adopt one of two different modes depending on the strategic character of current circumstances. While some situations prompt partisan solidarity, other situations encourage people to engage in open‐minded deliberation. We argue that the type of citizenship practiced depends on the engagement of the emotions of anxiety and aversion. Recurring conflict with familiar foes over familiar issues evokes aversion. These angry reactions prepare people for the defense of convictions, solidarity with allies, and opposition to accommodation. Unfamiliar circumstances generate anxiety. Rather than defend priors, this anxiety promotes the consideration of opposing viewpoints and a willingness to compromise. In this way, emotions help people negotiate politics and regulate the kinds of citizenship they practice.  相似文献
