Abstract

This article develops and tests a model that explains election outcomes on the basis of party strategy. It employs a new comparative dataset linking representative mass surveys from six European countries with Twitter analysis of campaign activity. The expectation is that parties whose issue agendas exploit electoral opportunities while avoiding risks will be rewarded at the polls. These risks and opportunities are modelled using issue yield, a general framework summarising public support, electoral alignments, and party credibility. Empirically, the article traces a three-step process: (1) the configuration of electoral risks and opportunities (which is captured through public opinion surveys) guides party communication (measured with Twitter data), and to the degree that (2) parties design their campaigns strategically (identified through issue yield), this in turn (3) improves their electoral performance (measured using official statistics). The analysis explains some of the most salient election outcomes of recent years.  相似文献

In the present work we show a forensic case study carried out in a mountainous environment. Main objective was to locate a clandestine grave which is around 10–20 years old and contains human remains of one individual and a metallic tool, probably a pick. Survey design started with an experimental burial of a pick at the expected depth (1 m) as well as the calculation of synthetic radargrams in order to know if the 250 MHz antenna was suitable for its detection and to have a record of the reflection of the pick. Conclusions extracted from the experiments together with rough terrain conditions suggested the use of the 250 MHz antenna which allowed a good compromise between target detection and dense grid acquisition of an extensive survey area.  相似文献

Sudden cardiac death is a significant cause of mortality in adults with congenital heart disease (CHD). The Cook County Medical Examiner's Office database was queried for cases of CHD as a cause of death in the period between July 2008 and April 2019. Twenty-two cases were identified, including 11 decedents with simple defects and 10 decedents with complex defects. All of the subjects were in apparent good health at the time of death. In the absence of other obvious causes of death, simple defects were considered cases of sudden cardiac death. Significant cardiac morphological changes were common in complex defects. While 16 cases had known, diagnosed/treated CHD, 5 cases had no diagnosis prior to autopsy. In these cases, the ability to recognize CHD (sometimes subtle) helped in determining the causes of death. Therefore, forensic pathologists must be able to properly recognize various forms of CHD and request consultations, when needed.  相似文献

The present article aims to uncover the different meanings attached to land ownership in Palestine during the late Ottoman and British Mandate eras and to show how a ‘modern’ understanding of ownership was imposed on the local population, particularly the fellahin (peasants), without a consideration of their needs and traditions. Many widespread claims are challenged, first and foremost the one according to which, at the time of the partition of Palestine (1947), ‘over 70 percent’ of it did not ‘legally’ belong to the local Arab majority, but to the British Mandate power, an assumption that has had political, cultural and social ramifications that have lasted until the present day.  相似文献

AIM:To examine whether acupuncture can prevent prolonged postoperative ileus(PPOI)after intraperitoneal surgery for colon cancer. METHODS:Ninety patients were recruited from the Fudan University Cancer Hospital,Shanghai,China. After surgery,patients were randomized to receive acupuncture(once daily,starting on postoperative day 1, for up to six consecutive days)or usual care.PPOI was defined as an inability to pass flatus or have a bowel movement by 96 h after surgery.The main outcomes were time to first fl...  相似文献

Abstract:  This article provides an overview of the practical problems which arise in ensuring the effective independence of central banks in the EU, drawing on the European Central Bank's consultative experience. Four aspects of central bank independence are discussed separately: functional, institutional, personal and financial. The possible issues raised by central bank involvement in prudential supervision are touched upon. The main conclusion of the article is that a set of legal provisions is generally not sufficient to ensure proper central bank independence; a culture of respect for independence, including its limits, among all parties involved is essential.  相似文献

The aim of this article is to explore identity dynamics of unit and department leaders in a healthcare setting using both social identity and social exchange theories. In particular, we developed a mediational moderated model in which supervisor trust indirectly influences identification with a subordinate level (i.e., the clinical unit) through its effect on identification with a superordinate level (i.e., the organization as a whole). Furthermore, we predicted and found that this relation is moderated by organizational tenure, contract breach, and the clinical-manager's role (heads of clinical units vs. chairs of departments). We tested our hypotheses with doctors of a large public hospital in northern Italy. A total of 370 doctors completed questionnaires measuring organizational and unit identification, supervisor trust, and contract breach. Results supported our hypotheses: supervisor trust was related to unit identification through its effect on organizational identification. As expected, this relation was stronger for more tenured department chairs, and for those doctors who perceived less contract breach.  相似文献
