Adrenocorticotropic hormone (ACTH) is involved in systemic reactions to stress. The aim of the present study was a comprehensive analysis of serum and cerebrospinal fluid (CSF) levels of ACTH, and the pituitary immunohistochemistry with special regard to fatal hypothermia in routine forensic autopsy cases (n=162: 5-97 years of age; 114 males and 48 females; 4 h to 3 days postmortem, median, 19.2 h). The ACTH concentrations were independent of the postmortem time, gender, or age of the subjects. The serum ACTH level was similar to the clinical reference value for sharp instrument injury, fire fatality, and hypothermia, but was lower in other groups including hyperthermia, in particular for asphyxia and poisoning. The CSF level was usually much higher than the serum level, but was significantly lower for hypothermia and hyperthermia than in other groups (p<0.01). The rate of ACTH-immunopositivity in the anterior pituitary was low in cases of fatal hypothermia and hyperthermia, while it was high in cases of blunt injury, fire fatality, and acute ischemic heart disease. These observations showed that ACTH levels in the serum and CSF depended on the cause of death. The serum level was maintained despite a low CSF level and pituitary immunopositivity for fatal hypothermia, while the serum and CSF levels as well as pituitary immunopositivity were decreased for hyperthermia.  相似文献

The public sector frequently confronts a heightened societal turbulence triggered by an increasing number of unpredictable and disruptive economic, political, and environmental crises. How can the public sector respond to this challenge? This article argues, first, that to continue to provide relevant solutions, public governance must be robust in the sense of adapting and innovating policies, programs, and services in ways that facilitate the achievement of basic public ambitions, functions, and values in the face of challenges, stressors, and threats. Second, to build robust governance, public managers must engage in bricolage and become bricoleurs in order to flexibly combine elements from competing and co-existent public governance paradigms. Doing so necessitates the construction of institutions conducive to bricolage, that is, institutions that are characterized by a high degree of flexibility that allows for experimentation; institutions that foster inclusive deliberation, knowledge sharing and joint learning; and institutions that balance centralization with distributed agency.  相似文献

Abstract. This article examines if and why mechanisms exist at the individual citizen level that may contribute to public sector growth — and whether such mechanisms can be altered through provision of information about the costs of public services.We test and find empirical support for the theory of fiscal illusion according to which citizens underestimate the costs of public services and therefore demand more public spending than if they had been fully informed. We also develop and find empirical support for a theory of asymmetrical illusions. This theory claims that producers and users of public services are more spending–minded than ordinary taxpayers — and that limited rationality contributes to this difference. However, the provision of information about the unit costs of public services can weaken these mechanisms of fiscal illusion and asymmetrical illusions. The test is based on tabular, logit, and experimental analysis of survey data from Odense, a Danish city with 175,000 inhabitants.  相似文献

In both academic literature and policy discourse, ex-combatants are at times depicted as a threat to peace rather than agents of positive change. However, many of my ex-combatant interlocutors in Burundi were working actively on conflict resolution and peace-building projects. In addition, their experience and knowledge of combat was frequently stated as a deterrent for going back to such a situation. Though it may seem contradictory, the reasons my informants gave for having joined the war sounded remarkably similar to motivations for social activism. They usually expressed it as a desire to contribute to a better, more just, community. I argue that ideology played an important part in motivation to join armed groups during the war and carries over in participation in social activism today. These decisions need not be seen as polar opposites, but rather as similar motivations towards contributing to positive change taken in different circumstances.  相似文献

Initially, governance networks were intended as tools for making public governance more effective. Yet, scholars have argued that governance networks also have the potential to democratize public governance. This article provides an overview of theoretical arguments pertaining to the democratizing impact of governance networks. It claims that the initial celebration of the pluralization of public governance and the subsequent call for a democratic anchorage of governance networks should give way to a new concern for how governance networks can strengthen and democratize political leadership. Tying political leadership to networked processes of collaborative governance fosters ‘interactive political leadership’. The article presents theoretical arguments in support of interactive political leadership, and provides an illustrative case study of a recent attempt to strengthen political leadership through the systematic involvement of elected politicians in local governance networks. The article concludes by reflecting on how interactive political leadership could transform our thinking about democracy.  相似文献

ABSTRACT

How do we study social media technology? While social semiotics provides an extensive toolkit for analysing multimodal texts and semiotic practices, the study of social media as semiotic technology poses a significant challenge to existing research methodologies. In this article, we present a social semiotic framework that allows us to describe in analytical details the multimodal meaning potentials offered by digital social media technology and connect these to multimodal text-making and semiotic practices while underscoring the role of technology. Our framework is organized around seven interrelated and inherently informed dimensions: (1) multimodality, (2) practice, (3) the social, (4) medium, (5) the material, (6) the historical, and (7) the critical. This framework could pertain to most types of semiotic technologies, but will here be developed for accounting for social media technologies, and its viability will be illustrated with examples from Instagram. By developing this framework, we aim at elaborating the theoretical basis and analytical tools of social semiotics, and thereby contributing to bringing forward increased understanding of how social media technology enables making, enacting and managing meaning.  相似文献

A critical election is generally defined as one in which the decisive results of voting reveal a sharp alternation of pre‐existing cleavage(s) and voting patterns, and the dealignment or realignment made between parties is lasting. A critical election can be caused by various factors and in this article the authors analyse whether the global credit crunch in 2008 set things in motion in Iceland, resulting in the 2009 election as a critical election. In that election, the electoral relevance of voters’ psychological attachment to parties and of ideological distances to them weakened, whereas party competence perceptions increased in importance for vote choices. Attachment to parties and ideological distances are factors that are generally stable and change slowly over time, while party competence is influenced by which issues are of importance at the time of the election. This indicates that, in 2009, a restructuring of the determinants of the vote occurred; a pattern of changes that is typical for a critical election. Evidence is found that the importance of party sympathy increases again in the 2013 election, indicating a realignment, rather than a dealignment, occurring in the wake of the 2009 election.  相似文献

Lipsky (1980) pointed out that street-level bureaucrats (SLBs) are important policymakers due to the discretion they exercise and argued from a structural perspective that these workers manifest relatively similar coping behaviors owing to their shared working conditions, characterized by chronically limited resources and non-voluntary clients. Using data from a national survey of municipal child welfare caseworkers in Denmark, we further develop Lipsky's theory from an agency perspective by focusing on variation in coping among SLBs and examining the extent to which such variation is explained by SLBs’ attitudes towards the target group, the objectives and content of their jobs, and their perceptions of the capacity of their institutions. We find that SLBs’ aversion to and tolerance of the client group, their perceptions of institutional capacity in terms of municipal resources and local political inefficacy, and their conceptual modification of job contents are all related to their use of coping.  相似文献

‘Responsibility to protect’ (R2P) is an ‘emerging norm’ of international relations, which has been invoked with the intervention in Libya in 2011. Even though this intervention was demanded by several Third World countries and organisations, these have subsequently had second thoughts about the matter and have come to regard R2P as Western neo-imperialism. This article seeks to explain this apparent paradox, with a special focus on India. It also identifies possible compromises by advocating a broader approach to R2P, stressing the responsibility to prevent and to rebuild. It also draws attention to ‘R2P lite’, including the protection of civilians in armed conflicts.  相似文献
