Abstract. Palle Svensson in this issue of EJPR has objected to the characterisation of Danish voters made by Franklin and others who, in various publications, expounded the thesis that on issues of low salience, referendum votes tend to follow party lines. Svensson finds evidence that the Maastricht Treaty was not an issue of low salience to Danish voters in the ratification referendums conducted there, and gives other details of the evolution of public opinion regarding Europe that clarify the circumstances in which our thesis should apply. In the light of his arguments, this Comment presents a more nuanced version of the thesis that learns from the Danish case, and should be of greater utility than our earlier version in helping to interpret the role of government standing in referendum outcomes. 相似文献

The concentration of thyreoglobulin (tg) was determined for death caused by hanging, strangulation by ligature, and throttling. Cases of sudden death (traumatic aortic rupture, penetrating wounds of the heart) were used for comparison. The mean values in cases of hanging (149.9±202.3 ng/ml), strangulation by ligature (193.1±173.3), manual strangulation (561.6±173.9) are distinguishable from violent acute deaths (23.3±27.6) and living healthy individuals (17.3±16.1). By means of statistical comparisons, significant differences were found between throttling and strangulation by ligature and between throttling and hanging (adjusted P<0.001). In connection with examination of the bodies high tg values can be regarded as a vital reaction in obstructive asphyxia. 相似文献

Threatening and otherwise inappropriate letters to members of the United States Congress 总被引:2,自引:0,他引:2

The authors examine the characteristics of threatening and otherwise inappropriate communications sent to members of the U.S. Congress by a sample of 86 subjects, 20 of whom threatened assassination. We quote excerpts from these letters and provide quantitative data on such variables as the volume, duration, form, and appearance of such communications; the enclosures; the subjects' perceived relationships to the recipients; the thematic content of the communications; and the messages and threats communicated. Comparisons between 43 subjects who pursued encounters with members of Congress and 43 who did not revealed 17 factors associated with such pursuit. In this population, threateners were significantly less likely to pursue an encounter than inappropriate letter writers who did not threaten, regardless of the type of threat or the harm threatened. Inappropriate letters to members of Congress are compared with those directed to Hollywood celebrities. Mentally disordered persons writing to public figures often mention and sometimes threaten public figures other than those to whom the letters are addressed, which raises important issues regarding notification of endangered third parties and the sharing of information among protective agencies. 相似文献
