This study uses a real national crisis, South Korea's 2014 Sewol ferry disaster, to examine how publics exposed to partisan media perceive the attribution of crisis responsibility and government trust differently. The study also investigates the mediating role of the attribution of crisis responsibility on the relationship between partisan media and government trust. The results demonstrate that citizens' partisan selective exposure influence their polarized perceptions of crisis responsibility and their trust in government. The attribution of crisis responsibility partially mediated the effects of partisan media on government trust. This study suggests the importance for government public relations to understand partisan media users so that public relations managers can engage and communicate effectively with all citizens during a national crisis.  相似文献

Climate change has disastrous impacts in the developing world and confronts countries like India with immense challenges. The dilemma of addressing these challenges encourages the appearance of new modes of agency. However, the extent to which new agents are able to address these challenges depends on several factors. The aim of this article is to examine these factors and how they affect the ways in which climate change-related challenges to development are tackled in the case of the Indian wind energy sector. By firstly examining the attributes and capabilities of the different actors and secondly applying a stakeholder network analysis, the article identifies different characteristics that support the effective and efficient deployment of wind energy in one Indian state and hinder it in another.  相似文献

During a 6 month period (July 2010-January 2011) we observed 12 fatal intoxications and 22 non-fatal cases related to the drug paramethoxymethamphetamine (PMMA) in Norway (4.8 mill inhabitants). This toxic designer drug, also known as "Death", is occasionally found in street drugs offered as "ecstasy" or "amphetamine". The present study aimed to evaluate the cause of death, and to compare the PMMA blood concentrations in fatal and non-fatal cases. Methods for identification and quantification of PMMA are presented. The median age of fatalities was 30 years (range 15-50) with 67% males; in non-fatal cases 27 years (20-47) with 86% males. In the 12 fatalities, the median PMMA blood concentration was 1.92 mg/L (range 0.17-3.30), which is in the reported lethal range of 0.6-3.1 mg/L in peripheral blood and 1.2-15.8 mg/L in heart blood. In the 22 non-fatal cases, the median PMMA concentration was 0.07 mg/L (range 0.01-0.65). Poly-drug use was frequent both in fatal and non-fatal cases. The PMA concentrations ranging from 0.00 to 0.26 mg/L in both groups likely represented a PMMA metabolite. Three fatalities were attributed to PMMA only, six to PMMA and other psychostimulant drugs, and three to PMMA and CNS depressant drugs, with median PMMA concentrations of 3.05 mg/L (range 1.58-3.30), 2.56 (1.52-3.23) and 0.52 mg/L (0.17-1.24), respectively. Eight victims were found dead, while death was witnessed in four cases, with symptoms of acute respiratory distress, hyperthermia, cardiac arrest, convulsions, sudden collapse and/or multiple organ failure. In summary, all fatalities attributed to PMMA had high PMMA blood concentrations compared to non-fatal cases. Our sample size was too small to evaluate a possible impact of poly-drug use. A public warning is warranted against use and overdose with illegal "ecstasy" or "speed" drugs.  相似文献

This paper is focused on the preparation of samples for laser microdissection (LM) in forensic casework. In forensic genetics, it is essential to preserve and separate cellular traces during sample preparation, as they are usually gathered in very small amounts and are often contaminated with undesired cells. This is made possible by laser microdissection, a technique developed to cut cells or tissue of a certain type from a microscopical specimen by UV laser and catapult them directly into a PCR reactor. This method minimizes the risk of getting inconclusive, mixed DNA profiles due to contamination by foreign DNA and also supplies information about the cellular origin of a DNA profile. A method for optimized fixation and staining of spermatozoa for laser microdissection was established. Four different fixation methods combined with two staining methods were tested on two different microscope slides. Moreover, the effect of a blocker pen to contain the specimen on the slide was investigated.  相似文献

Issue importance mediates the impact of public policy issues on electoral decisions. Individuals who consider that an issue is important are more likely to rely on their attitudes toward that issue when evaluating candidates and deciding for whom to vote. The logic behind the link between issue importance and issue voting should translate to a link between issue importance and performance voting. Incumbent performance evaluations regarding an issue should have a stronger impact on the vote choice of individuals who find that issue important. The analysis demonstrates that there is a significant interaction between performance evaluations and issue importance. People concerned about an issue assign more weight to their evaluations of the government's performance on that issue when making up their mind.  相似文献

Dominance in the peer group is important for adolescents. Resource Control Theory posits that both coercive and prosocial (positively assertive) strategies are associated with dominance. Combining Resource Control Theory with Socioanalytic Theory on personality, we hypothesized that inspiring group members would be an additional effective strategy. This study examined whether the three behavioral strategies and two types of social skills (social competence and manipulation) predicted dominance (resource control and popularity). Participants were 619 Dutch adolescents (Mage?=?13.1; 47% female) in the first grade of secondary school. They completed peer reports (behavioral strategies and dominance) and self-reports (social skills). Only inspirational and coercive strategies substantially predicted dominance. Main effects of social skills emerged. Moderation between strategies and social skills was only observed for girls (e.g., coercive strategy use was associated with more popularity for girls with higher levels of social manipulation skills). This study furthered our understanding of the predictors of dominance in adolescence by including inspirational behavior and examining prosocial and antisocial skills.  相似文献

The discipline of international relations (IR) is witnessing a "constructivist turn." In this article, we argue that the new preoccupation with constructivism provides a unique opportunity to further understanding between feminism and the IR mainstream. Feminism and constructivism share a commitment to an ontology of becoming that can serve as a common basis for conversation. Yet there are also profound differences between feminists and constructivists. First, most IR feminists approach gender and power as integral elements in processes of construction, whereas most constructivists consider power to be external to such processes. This failure to conceptualize power and gender as social and pervasive leads constructivists to miss an important part of the empirical reality of power politics. Second, constructivists tend to ignore the implications of a postpositivist epistemology, whereas for feminists the question of "Who knows?" is crucial. We argue that the constructivist failure to problematize the research process as a social (and therefore political) process of construction is logically inconsistent with an ontology of becoming. We introduce empirical materials to illustrate the advantages of feminist approaches. We hope to advance a dialogue between feminism and constructivism because the two approaches add to each other and in combination can yield better theoretical and empirical understandings of the world.  相似文献
