Values in pure and applied science 总被引:1,自引:1,他引:1
Sven Ove Hansson 《Foundations of Science》2007,12(3):257-268
In pure science, the standard approach to non-epistemic values is to exclude them as far as possible from scientific deliberations.
When science is applied to practical decisions, non-epistemic values cannot be excluded. Instead, they have to be combined
with (value-deprived) scientific information in a way that leads to practically optimal decisions. A normative model is proposed
for the processing of information in both pure and applied science. A general-purpose corpus of scientific knowledge, with
high entry requirements, has a central role in this model. Due to its high entry requirements, the information that it contains
is sufficiently reliable for the vast majority of practical purposes. However, for some purposes, the corpus needs to be supplemented
with additional information, such as scientific indications of danger that do not satisfy the entry requirements for the corpus.
The role of non-epistemic values in the evaluation of scientific information should, as far as possible, be limited to determining
the level of evidence required for various types of practical decisions. 相似文献

We present a new approach to the old problem of how to incorporate the role of the observer in statistics. We show classical probability theory to be inadequate for this task and take refuge in the epsilon-model, which is the only model known to us caapble of handling situations between quantum and classical statistics. An example is worked out and some problems are discussed as to the new viewpoint that emanates from our approach.Supported by the I UAP-III no. 9. 相似文献

Understanding the genetic structure of human populations is of fundamental interest to medical, forensic and anthropological sciences. Advances in high-throughput genotyping technology have markedly improved our understanding of global patterns of human genetic variation and suggest the potential to use large samples to uncover variation among closely spaced populations. Here we characterize genetic variation in a sample of 3,000 European individuals genotyped at over half a million variable DNA sites in the human genome. Despite low average levels of genetic differentiation among Europeans, we find a close correspondence between genetic and geographic distances; indeed, a geographical map of Europe arises naturally as an efficient two-dimensional summary of genetic variation in Europeans. The results emphasize that when mapping the genetic basis of a disease phenotype, spurious associations can arise if genetic structure is not properly accounted for. In addition, the results are relevant to the prospects of genetic ancestry testing; an individual's DNA can be used to infer their geographic origin with surprising accuracy-often to within a few hundred kilometres. 相似文献

The laboratory rat is one of the most extensively studied model organisms. Inbred laboratory rat strains originated from limited Rattus norvegicus founder populations, and the inherited genetic variation provides an excellent resource for the correlation of genotype to phenotype. Here, we report a survey of genetic variation based on almost 3 million newly identified SNPs. We obtained accurate and complete genotypes for a subset of 20,238 SNPs across 167 distinct inbred rat strains, two rat recombinant inbred panels and an F2 intercross. Using 81% of these SNPs, we constructed high-density genetic maps, creating a large dataset of fully characterized SNPs for disease gene mapping. Our data characterize the population structure and illustrate the degree of linkage disequilibrium. We provide a detailed SNP map and demonstrate its utility for mapping of quantitative trait loci. This community resource is openly available and augments the genetic tools for this workhorse of physiological studies. 相似文献

Human deprivation and suffering around the world are increasing despite the efforts of traditional aid-based approaches focused on alleviating poverty and improving the quality of life for marginalized communities. There is ample evidence that billions of dollars in aid money have been expended on development projects that are fundamentally unsustainable. On the other hand, social enterprises, which improve lives and livelihoods through practical market-based approaches, are growing in number. Systems Thinking can be especially helpful in navigating the complexity and chaos inherent in social ventures in developing communities. Lack of clarity in the roles, responsibilities, and returns for the various stakeholders epitomizes this chaos and is a major contributor to the failure of such projects. By employing Systems Thinking, entrepreneurs can establish accountability mechanisms, ensure equity for all stakeholders, and facilitate system sustainability. Though much research exists on both Systems Thinking and social enterprise, few sources discuss how Systems Thinking can be practically applied to conceptualize, build, and sustain social enterprises in an easy-to-understand manner. This paper synthesizes definitions of the tenets of Systems Thinking including interdependence, holism, multifinality, equifinality, differentiation, regulation, abstraction, and leverage points. The relevance of each of these tenets to social entrepreneurship is described, and further reinforced, with examples. A practical understanding of these tenets can empower entrepreneurs as they navigate chaotic environments in the quest for social enterprises that create win–win situations for all stakeholders. 相似文献

We performed a meta-analysis of 14 genome-wide association studies of coronary artery disease (CAD) comprising 22,233 individuals with CAD (cases) and 64,762 controls of European descent followed by genotyping of top association signals in 56,682 additional individuals. This analysis identified 13 loci newly associated with CAD at P < 5 × 10?? and confirmed the association of 10 of 12 previously reported CAD loci. The 13 new loci showed risk allele frequencies ranging from 0.13 to 0.91 and were associated with a 6% to 17% increase in the risk of CAD per allele. Notably, only three of the new loci showed significant association with traditional CAD risk factors and the majority lie in gene regions not previously implicated in the pathogenesis of CAD. Finally, five of the new CAD risk loci appear to have pleiotropic effects, showing strong association with various other human diseases or traits. 相似文献

We carried out a genome-wide association study in 296 individuals with male-pattern baldness (androgenetic alopecia) and 347 controls. We then investigated the 30 best SNPs in an independent replication sample and found highly significant association for five SNPs on chromosome 20p11 (rs2180439 combined P = 2.7 x 10(-15)). No interaction was detected with the X-chromosomal androgen receptor locus, suggesting that the 20p11 locus has a role in a yet-to-be-identified androgen-independent pathway. 相似文献

Science denialism poses a serious threat to human health and the long-term sustainability of human civilization. Although it has recently been rather extensively discussed, this discussion has rarely been connected to the extensive literature on pseudoscience and the science-pseudoscience demarcation. This contribution argues that science denialism should be seen as one of the two major forms of pseudoscience, alongside of pseudotheory promotion. A detailed comparison is made between three prominent forms of science denialism, namely relativity theory denialism, evolution denialism, and climate science denialism. Several characteristics are identified that distinguish science denialism from other forms of pseudoscience, in particular its persistent fabrication of fake controversies, the extraordinary male dominance among its activists, and its strong connection with various forms of right-wing politics. It is argued that the scientific response to science denialism has to be conceived with these characteristics in mind. In particular, it is important to expose the fabricated fake controversies for what they are and to reveal how science denialists consistently use deviant criteria of assent to distort the scientific process. 相似文献
