A death resulting from tripelennamine overdose in a 19-year-old male Caucasian is reported. The patient died 7 h after ingesting approximately twenty 50-mg tripelennamine tablets. A concentration of 1.0 mg/100 ml was found in the blood. All tissue concentrations were measured by ultraviolet spectroscopy and verified by gas-liquid chromatography. Significant findings included pulmonary edema and multiple small petechial hemorrhages in the soft tissue of the scalp. 相似文献

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades. 相似文献

K. H. F. Dyson 《West European politics》2013,36(2):166-187
This article represents an attempt to analyse the complex historical processes of political change in Western Europe in the context of an explicit frame of enquiry. It is concerned to establish not only that the past illuminates the present but also that conceptual rigour and the purposive use of analysis provided by a framework of general ideas is as much relevant to making sense of the past as of the present. The model is a deliberate simplification and, of course, open to refinement. Its virtue is parsimony; its purpose, to enable indentification of the predominant type of political organisation in a concrete political situation. 相似文献
