The riskiness of state employee pension plan portfolios varies across states. We investigate whether this variation is related to how public employees and taxpayers share actuarial surpluses of pension accounts. We focus on two determinants of a plan’s asset mix: the relative influence of public employees to taxpayers; and whether a surplus-sharing contract is specified. Our theoretical model demonstrates that the effect of public employee influence on the asset mix is ambiguous. Our empirical results corroborate this complex theoretical result. In our theoretical and empirical analyses, if a surplus sharing rule is specified, plans adopt a more aggressive investment allocation.  相似文献

Among the best-known theorems of fiscal federalism is the presumed allocative and distributive equivalence between a lump-sum grant to a collectivity and a set of lump sum grants to the members of a collectivity. Interestingly, the simple elegance of the theorem is at odds with observed behavior. Grants to governments produce greater public spending than does tax reduction. Explanations of this "flypaper effect" range from misspecified econometric modeling to presumed behavior based on fiscal illusion. In this paper we show that theoretical equivalence exists in a model that recognizes only one tax share, the citizen voter's local tax share. When the model is expanded to include voters' federal tax shares as well as local taxes, non-equivalence and the flypaper effect become the rule, not the exception.  相似文献

Accidental hypothermia has been described in the forensic literature but reports of occurrence in hospitalized patients are rare. Associated anatomic lesions include acute hemorrhagic pancreatitis and characteristic acute gastric ulcers termed Wischnewski ulcers. We report here two patients with cirrhosis and ascites; one also had hepatocellular carcinoma. Portal vein thrombosis, acute hemorrhagic pancreatitis and Wischnewski ulcers were present in both. The clinical records documented hypothermia that progressed over several days. Temperature nadirs of 31.0 degrees C (87.8 degrees F) and 32.2 degrees C (90.0 degrees F) were recorded in each patient, respectively, one day before death, although each transiently reached temperatures that did not register on standard monitoring devices. This is the first report that chronicles antemortem body temperatures in hypothermic patients with Wischnewski ulcers and pancreatitis at autopsy. Also, the association of these findings with portal vein thrombosis and cirrhosis has not been previously described. We discuss this constellation of findings with regard to possible mechanistic interrelations.  相似文献

There are a number of forensic cases in which the identification of the epithelial cell type from which DNA originated would provide important probative evidence. This study aimed to develop a technique using histological staining of fixed cells to distinguish between skin, buccal and vaginal epithelium. First, 11 different stains were screened on formalin-fixed, wax-embedded cells from five women. Samples were analysed qualitatively by examining staining patterns (colour) and morphology (absence or presence of nuclei). Three of the staining methods – Dane's, Csaba's and Ayoub-Shklar – were successful in distinguishing skin epithelial cells from buccal and vaginal. Second, cells were smeared directly onto slides, fixed with one of five fixatives and stained with one of the three stains mentioned above. Methanol fixation, coupled with the Dane's staining method, specific to keratin, was the only technique that distinguished between all three cell types. Skin cells stained magenta, red and orange and lacked nuclei; buccal cells stained predominantly orange–pink with red nuclei; while vaginal cells stained bright orange with orange nuclei and a blue extracellular hue. This staining pattern in vaginal cells was consistent in samples collected from 50 women aged between 18 and 67. Identification of cell type from unlabelled micrographs by 10 trained observers showed a mean success rate of 95%. The results of this study demonstrate that histological staining may provide forensic scientists with a technique for distinguishing between skin, buccal and vaginal epithelial cells and thus would enable more conclusive analyses when investigating sexual assault cases.  相似文献

The policyholder's “duty to cooperate” is built into every liability insurance policy, either expressly or through the application of a state's common law. The scope of an insured's duty to cooperate is often difficult to discern, however, in terms of the type and extent of information that the insured should provide as part of the insurer's investigation of the underlying matter for which coverage is being sought. Traditionally, the duty to cooperate was intended to encourage information sharing to allow the insurer to afford the policyholder a comprehensive, informed defense to the underlying claimant's allegations. This article examines the scope of the duty to cooperate and how that duty impacts the insured's obligation to share some reasonable amount of information as part of the insurer's investigation and defense of the underlying claim, noting potential pitfalls and risks that may arise from information sharing.  相似文献

The use of pyrolysis mass spectrometry (Py-MS) and statistical analysis of mass spectra is introduced as a method for “finger-printing” strains of Streptococcus salivarius. The objective is to provide correlative evidence regarding the identity of suspects in cases of assault or rape involving bite-marks. The results of the analysis of isolates from two individuals are presented, illustrating the differentiation of S. salivarius at strain level according to the origin of the isolate.  相似文献
