Since the 1970s, climate change has dominated the international scientific and political agenda. In particular, the foundation of the Intergovernmental Panel on Climate Change at the end of the 1980s played a major role for the further enhancement of efforts in the field of climate change sciences. However, to understand the interaction of the worldwide coordination of climate change sciences as well as the role of the Intergovernmental Panel on Climate Change and its consequences, it is worthwhile to take a look at the self-conception of the Intergovernmental Panel on Climate Change’s tasks and work. This paper gives an idea of the history of international climate change science, its representation in public discourse and the role of the Intergovernmental Panel on Climate Change by comprehensively illustrating its tasks, organization and self-image. Furthermore, the article tries to argue that the hitherto accepted concept of science followed within this body fails to integrate the idea of scientific ethics. It can be concluded that the conception of science represented by the Intergovernmental Panel on Climate Change has heavily influenced worldwide attention to climate change, its becoming part of the political agenda as well as the ethical consequences. 相似文献

The measurement of human immunodeficiency virus ribonucleic acid levels over time leads to censored longitudinal data. Suitable models for dynamic modelling of these levels need to take this data characteristic into account. If groups of patients with different developments of the levels over time are suspected the model class of finite mixtures of mixed effects models with censored data is required. We describe the model specification and derive the estimation with a suitable expectation-maximization algorithm. We propose a convenient implementation using closed form formulae for the expected mean and variance of the truncated multivariate distribution. Only efficient evaluation of the cumulative multivariate normal distribution function is required. Model selection as well as methods for inference are discussed. The application is demonstrated on the clinical trial ACTG 315 data. 相似文献

Abstract Objective: Social norms campaigns are a cost-effective way to reduce high-risk drinking on college campuses. This study compares effectiveness of a “standard” social norms media (SNM) campaign for those with and without exposure to additional educational sessions using audience response technology (“clickers”). Methods: American College Health Association's National College Health Assessment questions are used to evaluate actual and perceived use. Additional survey questions assess individual exposure to the interventions. Results: The authors find “clicker” technology to be more effective than social norms poster media alone in reducing misperceptions of normative alcohol use for those students who attended clicker sessions. Conclusion: Poster SNM campaigns may be most effective when supported by group “clicker” heath-related sessions. 相似文献

Genomic analyses have shown that only 1.2 per cent of the genome is devoted to protein coding sequences (the most commonly invoked definition of genes), and that much of the remaining sequences are employed in regulation – that is, in responding to signals, first, from the immediate environment of the DNA, but ultimately from the distal environment – from the cytoplasm, from the environment outside the cell, and finally, from the environment beyond the organism. Such signals are not restricted to the simple physical and chemical stimuli that impinge directly on the DNA, on the surface of the cell, or even on the body as a whole: organisms with central nervous systems have receptors for forms of perception that are not only more complex but far longer range. Humans have especially sophisticated perceptual capacities, enabling them to respond to a wide range of complex visual, auditory, linguistic and behavioural/emotional signals in their extended environment. Research has recently begun to show that responses to such signals can extend all the way down to the level of gene expression. The question is this: to what extent are we witnessing (at last) a rapprochement between the natural science of biology and the human sciences of sociology and anthropology, and to what extent do the new promises of synthesis merely reflect an expansion of older reductionist aims, threatening once again to marginalize rather than incorporate the insights of cultural analysis? As in my earlier discussion of the nature/nurture debate (2010), my focus will be restricted to the Anglo-American context. 相似文献

Visions are important to organizational effectiveness. Although providing vision has been identified as one of the behaviors that best captures organization-wide public relations leadership, little public relations research has focused on vision. Similarly, state health departments have drawn little interest among public relations scholars even though states are a central part of the nation's public health system. This study addressed the perceptions of the top public relations professionals at state health departments concerning vision and their involvement in the visioning process. The practitioners were nearly unanimous in their belief that organizational visions are important. However, results indicate that some top public relations practitioners at state health departments are not prepared to make optimal contributions to the visioning process. In order to take full advantage of opportunities to serve as organization-wide leaders, public relations practitioners should seek out information about visioning in order help chart their organization's future and enhance their careers. 相似文献

Incentives for cooperation may be enhanced substantially if a player can rely on the entire community to punish a partner who failed to cooperate. The ability of a player to report a defection to others can constitute a strong deterrent against defection if this report triggers a punishment imposed by the whole community. This paper studies the truth-telling problem in such a context. The paper presents a sequential equilibrium that supports cooperation in which a player unilaterally reports the play of a partner with strict incentives for truth-telling. It is shown, however, that desirable properties of equilibria described in the previous literature that assume truth-telling no longer exist. The implications of the results for practical examples, such as trading on eBay, are discussed. 相似文献

Evidence suggests that children and adults diagnosed with autism spectrum disorders (ASD) exhibit difficulties with postural control. Retrospective video studies of infants later diagnosed with ASD indicate that infants who eventually receive an ASD diagnosis exhibit delays in postural development. This study investigates early posture development prospectively and longitudinally in 22 infants at heightened biological risk for ASD (HR) and 18 infants with no such risk (Low Risk; LR). Four HR infants received an autism diagnosis (AD infants) at 36 months. Infants were videotaped at home at 6, 9, 12, and 14 months during everyday activities and play. All infant postures were coded and classified as to whether or not they were infant‐initiated. Relative to LR infants, HR infants were slower to develop skill in sitting and standing postures. AD infants exhibited substantial delays in the emergence of more advanced postures and initiated fewer posture changes. Because posture advances create opportunities for infants to interact with objects and people in new and progressively more sophisticated ways, postural delays may have cascading effects on opportunities for infant exploration and learning. These effects may be greater for infants with ASD, for whom posture delays are more significant. 相似文献
