ELSI (Ethical, Legal and Social Implications) initiatives are frequently attached to major science programmes. The expectation is that ELSI research will produce a practical advanced assessment of the impacts of technological development. Williams' overview of the field demonstrates that this encourages a mechanistic understanding of technological development leading to compressed foresight, i.e. the notion that the future is imminent in the present. The development of the ELSI domain in Canada has been characterised by an affinity between the types of knowledge valorised by the field and modes of legal reasoning, suggesting a legal variant of compressed foresight. The concept of juridification and an analysis of two related modes of legal reasoning (analogy and reflective equilibrium) shed light on the connection between legal reasoning and the ELSI field in Canada. The deployment of the aforementioned modes of legal reasoning enables law to define and operationalise difficult questions by drawing on currently existing principles and precedents. Thus, when legal modes of reasoning are brought to bear on ELSI questions, the future is made a calculable and manageable extension of the present, dovetailing with the ELSI field's requirement of pragmatic, advanced assessment. 相似文献

This article uses meta-analysis to develop a model integrating research on relationships between employee perceptions of general and work-family-specific supervisor and organizational support and work-family conflict. Drawing on 115 samples from 85 studies comprising 72,507 employees, we compared the relative influence of 4 types of workplace social support to work-family conflict: perceived organizational support (POS); supervisor support; perceived organizational work-family support, also known as family-supportive organizational perceptions (FSOP); and supervisor work-family support. Results show work-family-specific constructs of supervisor support and organization support are more strongly related to work-family conflict than general supervisor support and organization support, respectively. We then test a mediation model assessing the effects of all measures at once and show positive perceptions of general and work-family-specific supervisor indirectly relate to work-family conflict via organizational work-family support. These results demonstrate that work-family-specific support plays a central role in individuals' work-family conflict experiences. 相似文献

It is generally held that anxiety is characterized by an attentional bias for threatening information. In recent years there has been an important debate whether these biases reside at the level of attentional selection (threat detection) or attentional processing after threat detection (attentional disengagement). In a visual search task containing emotional facial expressions, eye-movements were examined before and after threat detection in high and low trait anxious individuals to further elucidate the temporal unfolding of attentional bias. Results indicated that high-anxious individuals neither showed facilitated orienting to threat nor impaired disengagement of visual attention from threat. Interestingly, the presence of threat in the visual search display was associated with increased decision times in high-anxious individuals. These results challenge some of the current views on attentional bias to threat but indicate that emotional information reduces processing efficiency in anxiety. 相似文献

We develop a predicate logical extension of a subintuitionistic propositional logic. Therefore a Hilbert type calculus and a Kripke type model are given. The propositional logic is formulated to axiomatize the idea of strategic weakening of Kripke's semantic for intuitionistic logic: dropping the semantical condition of heredity or persistence leads to a nonmonotonic model. On the syntactic side this leads to a certain restriction imposed on the deduction theorem. By means of a Henkin argument strong completeness is proved making use of predicate logical principles, which are only classically acceptable. 相似文献

布洛赫被誉为20世纪“乌托邦哲学家”。在他看来,乌托邦是20世纪一个重要的哲学一马克思主义范畴,乌托邦远没有限定在社会领域里,它也存在于艺术中,特别是存在于受表现主义影响的诗人和画家中。具体的乌托邦是一种斗争原理、一支社会力量,它预示政治上的未来远见、新事物的未发现状态。更美好生活的乌托邦不仅照亮未来,也照亮当下。一个马克思主义者不应传播悲观主义。 相似文献

Before World War II, Czechoslovakia went through its constituting process, including the development of an educational system. We made an analysis of Czechoslovak discussions about educational uses of intelligence tests from a discourse-theoretic and social constructionist perspective. In particular, we examined which connotations became associated with the concept "intelligence" in educational scientific publications about possible educational uses of the newly introduced tests in the years 1900-1939. Results substantiate the inextricable entwining of the meaning of "intelligence" with the unique characteristics of the historical situation in Czechoslovakia before World War II. 相似文献

Evidence for a gene-environment interaction in predicting behavioral inhibition in middle childhood 总被引:8,自引:0,他引:8

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood. 相似文献

Merging the senses into a robust percept 总被引:1,自引:0,他引:1
To perceive the external environment our brain uses multiple sources of sensory information derived from several different modalities, including vision, touch and audition. All these different sources of information have to be efficiently merged to form a coherent and robust percept. Here we highlight some of the mechanisms that underlie this merging of the senses in the brain. We show that, depending on the type of information, different combination and integration strategies are used and that prior knowledge is often required for interpreting the sensory signals. 相似文献

Using placebos in day-to-day practice is an ethical problem. This paper summarises the available epidemiological evidence
to support this difficult decision. Based on these data we propose to differentiate between placebo and “knowledge framing”.
While the use of placebo should be confined to experimental settings in clinical trials, knowledge framing — which is only
conceptually different from placebo — is a desired, expected and necessary component of any doctor-patient encounter. Examples
from daily practice demonstrate both, the need to investigate the effects of knowledge framing and its impact on ethical,
medical, economical and legal decisions.
An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research
Today,” held in Warsaw, Poland on 12–13 April, 2003. 相似文献
