试论卡尔纳普的真理标准

卡尔纳普主张从哲学中清除形而上学。他拒斥行而上学．对综合命题提出了确证代替证实的标准,后来走向概率研究,为现代归纳逻辑发展开辟了新方向;对于分析命题则从句法分析到语义分析,为语言哲学和分析哲学作出了贡献。然而他主张的物理主义却并未成为现实。     

A multi-analysis approach for space–time and economic evaluation of risks related with livestock diseases: The example of FMD in Peru

This study presents a multi-disciplinary decision-support tool, which integrates geo-statistics, social network analysis (SNA), spatial-stochastic spread model, economic analysis and mapping/visualization capabilities for the evaluation of the sanitary and socio-economic impact of livestock diseases under diverse epidemiologic scenarios. We illustrate the applicability of this tool using foot-and-mouth disease (FMD) in Peru as an example. The approach consisted on a flexible, multistep process that may be easily adapted based on data availability. The first module (mI) uses a geo-statistical approach for the estimation (if needed) of the distribution and abundance of susceptible population (in the example here, cattle, swine, sheep, goats, and camelids) at farm-level in the region or country of interest (Peru). The second module (mII) applies SNA for evaluating the farm-to-farm contact patterns and for exploring the structure and frequency of between-farm animal movements as a proxy for potential disease introduction or spread. The third module (mIII) integrates mI–II outputs into a spatial-stochastic model that simulates within- and between-farm FMD-transmission. The economic module (mIV) connects outputs from mI–III to provide an estimate of associated direct and indirect costs. A visualization module (mV) is also implemented to graph and map the outputs of module I–IV. After 1000 simulated epidemics, the mean (95% probability interval) number of outbreaks, infected animals, epidemic duration, and direct costs were 37 (1, 1164), 2152 (1, 13, 250), 63 days (0, 442), and US$ 1.2 million (1072, 9.5 million), respectively. Spread of disease was primarily local (<4.5 km), but geolocation and type of index farm strongly influenced the extent and spatial patterns of an epidemic. The approach is intended to support decisions in the last phase of the FMD eradication program in Peru, in particular to inform and support the implementation of risk-based surveillance and livestock insurance systems that may help to prevent and control potential FMD virus incursions into Peru.

蜀宣花牛体型外貌、线性评定及生理指标测定

[目的]为了充分了解牛群的体型外貌及生理指标情况,我们对牛群体型外貌进行了评定、同时对牛群的毛色、肤色、踢、角及生理指标进行了调查研究。[方法]通过对牛群生理指标测定、体型外貌评定及毛色、肤色、踢、角颜色和形状分析。[结果]表明:蜀宣花牛肉用指数公母牛分别为5.3769和4.0725,低于国外专门化肉牛品种,但也明显高于国内几个比较有名的地方牛品种,由此说明,蜀宣花牛的肉用指数界于专用型肉牛和肉役兼用型牛之间。毛色以黄白花和红白花为主,占90.16%;皮肤颜色以纯粉色和粉色有斑点的为主,占96.92%;蹄质颜色以纯蜡黄色为主,占86.28%;角型以照阳角为主,占93.94%。成年母牛的生理指标分别为:体温平均38.38℃、心跳74.56次/min、呼吸18.74次/min和瘤胃蠕动2.84次/2min;体型外貌线性评定分析表明,蜀宣花牛母牛的14个性状中,除后房宽度、尻角度和乳房底部3个性状平均分略低于75分,强壮度、后房高度、乳头位置和乳静脉4个性状的平均分高于80分外,其余7个性状的平均分都在75~80分之间。[结论]从乳用性能的角度看,牛群的平均体型尚处在较理想型和理想型之间,还有待进一步选育提高。     

Survey and Analysis of Common Diseases of Laboratory Monkeys in Kunming Area

Survey and analysis of common diseases of laboratory monkeys are great significance to understand disease epidemiology, and formulate a set of scientific and reasonable measures for prevention and control disease, to improve the quantity and quality of laboratory monkeys, to ensure the accuracy of the animal experiment results. Through the investigation of the sick and dead animals of a large-scale laboratory monkeys breeding facility in Kunming area in 2014, the animals were classified depends on the main diseases, and the diseases were classified according to adult and juvenile animals, data were analyzed by Excel Office 2010 software. The results showed the common diseases of laboratory monkeys included the digestive system, respiratory system, trauma, reproductive system, and locomotor system disease, which were 47.45%, 13.06%, 12.10%, 11.46% and 8.92% separately; Common diseases included diarrhoea, soft tissue injuries, abortion, lobar pneumonia, dysentery, arthritis, intestinal pneumatosis, chronic colitis, and extreme bad nutrition, the ratio were 18.47%, 11.15%, 8.91%, 8.28%, 8.28%, 7.96%, 5.10%, 5.10% and 5.09% separately. Comprehensive analysis of common diseases and disease occurrence causes of the laboratory monkeys, suggesting that providing better quality laboratory monkeys for scientific research only by constantly improving the scientific breeding management level, constantly strengthening veterinary capacity, mastering the theoretical knowledge and scientific diagnosis method.
