Given the vast amounts of research on party competition, party strategy, political communication and electoral campaigning, surprisingly little attention has been devoted to the study of national party elites' perceptions of voters and public opinion. This article argues that the mindset of leading party officials, and more specifically their perceptions of voter and public opinion rationality, driving forces and knowledge, is a much‐neglected explanation for why parties adopt the electoral strategies they do. Analysed here are unique internal party documents from two Swedish parties during the period 1964 to 1991: the Social Democratic Party and the Conservative Party. A simple analytic framework is proposed for the study of party elite perceptions of voters and public opinion. In contrast to the overwhelmingly pessimistic view of voter rationality that still prevails in contemporary research, the findings presented in this article suggest that national party elites in general have had a surprisingly positive view of voters and, in particular, public opinion. Perceptions of voters and public opinion were largely unaffected by the parties' electoral fortunes, and did not become gloomier over time.  相似文献

Understood primarily as a meta-narrative reflecting citizens' reluctance to accept migration and Islam as permanent components of their society, grass-roots protests against mosque construction also highlight a democratic paradox regarding multi-level governance: while national governments bear chief responsibility for ensuring fundamental religious freedoms, local authorization procedures affecting mosque construction (e.g. zoning, building permits) have rendered communal spaces a Ground Zero for the regulation of Islamic faith communities. While similar protests have taken place across Europe, German officials face special problems in responding to challenges by neighbourhood groups, rooted in the complicated nature of federalism, the legacy of National Socialism and a new, if misunderstood, element of ‘militant democracy’ at local levels. The Pankow-Heinersdorf case, staged on the outskirts of eastern Berlin, shows that multifaceted interventions can help contesting parties come to terms with religious differences, develop their networking and dialogue skills and actually contribute to more effective democratic participation at the local level.  相似文献

While terrorist organizations have been analyzed for their motivations and tactics, little has been done to develop a systematic understanding of what makes some groups more dangerous than others. Knowing what makes some groups more threatening than others, or what conditions can influence a single group to become more or less of a threat, would help governments to prioritize resources during counterterrorism efforts. Using an approach similar to Ted Robert Gurr's assignment of a risk score to identify impending minority group rebellion, this article develops and tests a set of terrorist organizational characteristics. A two-phased approach is used. First, the authors identify key characteristics that could be anticipated to drive groups to be more active or deadly. The characteristics were identified and measured for terrorist groups for 1990–1994. The authors test group characteristics against subsequent group violence intensity from 1995 to 1999. Findings indicate that some group characteristics, such as religious ideology and group size, are important to understanding a group's relative level of violence. Though the study focused on a relatively short period of time, the findings indicate that a more comprehensive study of the impact that group characteristics have on violence levels would be a worthwhile undertaking.  相似文献

Public administration scholars have little understanding of the operation of values within public sector organizations. Because the institutional values literature suggests that behavior consistent with American values by public organizations and officials can make a difference in successful policy outcomes, this research focuses on identifying the espoused and enacted value perspectives for two sets of U. S. government officials, presidents and senior executives. Through a content analysis of agency mission statements and speeches of Presidents Bush, Clinton and Bush, a subject matter analysis of executive orders, and a survey of senior executives, the following information is identified: The three presidents espouse the same set of values (i.e., ethics, performance, and support) in their speeches, but enact only one common value (i.e., commitment) in their executive orders. Although not statistically significant, two (i.e., performance and ethics) of the three top values in the agency mission statements are consistent with the values of the presidents. Senior executive perceptions of the most important values (i.e., authority, reward, and support) differ from the presidents. This unexpected difference lends support to Woodrow Wilson’s politics/administration dichotomy in that senior executives focus on values that address policy implementation while presidents focus on values related to politics.  相似文献

We studied sexually dimorphic differences in the ilium using geometric morphometric analysis of 10 osteometric landmarks recorded by multislice computed tomography, based on three‐dimensional reconstructions of 188 children (95 boys, 93 girls) of mixed origins living in the area of Toulouse, southern France, and ranging in age from 1 to 18 years. We used geometric morphometrics methodology first to test sexual dimorphism in size (centroid size) and shape (Procrustes residuals) and second to examine patterns of shape change with age (development) and size change with age (growth). On the basis of statistical significance testing, the ilium shape became sexually dimorphic at 11 years of age, although visible shape differences were observed as early as 1 year of age. There was no statistically significant difference in size between sexes. Trajectories of shape (development) and size (growth) differed throughout ontogeny and between sexes.  相似文献

A 20‐year‐old man, a cocaine addict and regular ecstasy user, with a medical history of allergic asthma died after ingesting half a tablet earlier the same day. The white tablet, stamped with a “smiling sun” logo looked very much like an ecstasy tablet and was sold as such. He experienced a severe asthma attack just after ingesting the half tablet and it evolved over the next few hours into fatal cardiorespiratory arrest. Biological samples, taken after embalming, were analyzed by high‐performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS). Analysis revealed meta‐chlorophenylpiperazine (mCPP) in concentrations of 45.8 mg in a similar tablet obtained later from the drug dealer, 5.1 ng/mL in the bile, 0.3 ng/g in the liver, 15.0 ng/mL in the urine, and its absence in a hair sample (<0.02 ng/mg), which indicated he was not a regular user (whereas strong concentrations of MDMA and cocaine were found in the hair). Interrogated by the police after his arrest, the dealer said that he had sold the victim and for the very first time two tablets with the same “smiling sun” logo. The tablet used for analysis was from the same brand as the one ingested by the victim. The autopsy excluded other causes of death, while the histological analyses showed a large number of polynuclear eosinophils in the bronchial walls, confirming the asthmatic pathology. None of the other organs examined (larynx, liver, heart, adrenal glands, and kidneys) showed any distinctive signs, and in particular no inflammatory infiltrate. The death was the result of an asthma attack in an asthmatic person, violently decompensated following ingestion of approximately 20 mg of mCPP.  相似文献
