试论牛羊腐蹄病的防治

牛羊蹄腐病能够引起蹄部炎症.病发严重时炎症从蹄步向腱鞘、关节骨蔓延,导致牛羊体温升高,甚至引发全省性的炎症、褥疮及反复的创伤后再轧染,最终引起败血症及死亡.该病的预防意义大于治疗.基于此,本文来探讨牛羊蹄腐病的发生病因及防治方法.旨在为牛羊蹄腐病的健康预防提供一些参考,降低因该病带来的养殖经济损失.

欧盟和美国的竞争政策及对中国的启示

正从国外经验看,市场经济越发展,市场越开放,竞争和竞争政策的地位就越重要,发挥的作用就越大。成熟市场经济国家的调控手段有财政政策、货币政策、贸易政策、竞争政策。落实竞争政策有利于构建和维护公平竞争的市场经济秩序。欧美在竞争执法方面历史较长,积累了较多经验。理解、借鉴别国经验,首先应该用审慎的态度开展比较性研究,对一些重复出现的问题进行比对和分析,在政府履职方面寻找共通内容。一、竞争政策的地位和作用     

人力资本、文化融入度和乡村劳动力转移——以新疆乡村劳动力转移为例

无论是"三农"问题还是城乡统筹发展的解决途径,众多学者始终把乡村劳动力转移、乡村人口非农化以及城市化来吸纳更多乡村劳动力作为研究重点。但是西部地区,尤其是从少数民族较集中地区劳动力转移实践来看,传统的劳动力转移理论和政策建议不能够全面地解释劳动力转移过程中的一系列新问题。本文以新疆维吾尔自治区为例,试图通过人力资本、文化融入度和转移偏好角度,对此现象做出解释。     

竞争性的旅游业

澳大利亚和中国最近都经历了未曾预料到的旅游需求滑坡。过去10年里,两国都幸获到了国际旅游者的大量需求。为了满足需求,就使得旅游设施尤其是饭店业建设如雨后春笋般发展起来。举例说,澳大利亚在1983—88年间接待的短期旅游者人数从94.4万人次增加到225万人次。在中国,自从中共中央十一届三中全会以后,给旅游业以愈来愈多的重视。国     

Severity of alcohol-related motor vehicle crashes in British Columbia: case - control study

The objective of the present study was to compare the injury severity and vehicle damage severity rates of alcohol-related crashes with rates of non-alcohol-related crashes in British Columbia (BC). Injury severity rates and vehicle damage severity rates were taken from 2002 Insurance Corporation of British Columbia traffic collision data. The data were computed in order to compare the differences in injury severity and vehicle damage severity rates of alcohol-related vs. non-alcohol-related motor vehicle crashes. Case - control methods were used in this study to analyse the risk of alcohol-related crashes compared to non-alcohol-related crashes in BC. Odds ratios (OR) and 95% CI were calculated to estimate relative risks. In the case - control analysis, the risk of fatal collision was increased for those drinking and driving compared with those driving sober (OR 4.70; 95% CI 3.15 - 7.01). Risk of injury collision was increased for those drinking and driving compared with those driving sober (OR 1.32; 95% CI 1.19 - 1.37). Importantly, the risk of vehicle damage severity was increased for those drinking and driving compared with those driving sober (write-off vehicle OR 4.24; 95% CI 3.70 - 4.86, severely damaged vehicles OR 1.98; 95% CI 1.77 - 2.21). The study reinforces existing literature to suggest that current evidence is sufficient to show an increased risk of injury and fatality to drivers and occupants in alcohol-related crashes. This paper not only emphasizes this well-known relationship, but also such consequences as increased vehicle damage severity. The connection between drinking and severity of motor vehicle crashes is popularly believed and has now received substantial scientific support. There is strong justification for injury prevention experts and policy-makers to step up motor vehicle crash injury prevention advocacy by implementing evidence-based policies to reduce rates of alcohol-impaired driving in the province of BC. Most unintentional injuries in BC are related to motor vehicle crashes. Significant improvements can be made in these statistics by: increasing the use of occupant protection (safety belt and child restraint seats); reducing alcohol-related injuries through multiple strategies including corrections in the physical environment, extensive enforcement of drinking and driving laws and health promotion/education.     

战略带来意外的收获

什么是战略竞争?战略竞争就是大家都朝不同的方向上竞争,就是你选择你自己的目标,你是和自己竞争,而别人选择他们自己的目标。 想想这两者的不同,营运效益竞争导致竞争合流,每家公司的产品都一样,都采取低价战略,消费者没别的选择,只能选择最低价的产品。而战略竞争发展出别具特色的产品,使你和其他产品有所区别,创造出独特的价值,而消费者根据不同的需求选择他们想要的产品。     

为什么中国的汇率要钉住美元：基于日元的历史分析

从1994年到2005年7月21日，中国把其汇率固定在1美元兑换8．28元人民币的水平。此后的人民币汇率机制改革使得人民币汇率在严格控制下开始小幅升值。由于中国的劳动生产率增长相当迅速，贸易盈余持续增长，并积累了大量美元外汇储备。这引发了美国的“排华风潮”，并强烈要求人民币进一步升值。尽管人民币升值并不能降低中国的贸易盈余，但人民币升值的威胁将降低中国的名义利率——1978—1995年的“排日风潮”和日元升值就是如此。日元过度升值引起的通货紧缩，加之零利率的流动性陷阱，造成了20世纪90年代成为日本的“失去的十年”，在新千年里，这同样可能在中国重演。     

美国的饭店星级评定

每年,美国汽车协会(AAA)和莫比尔(Mobil)旅行指南都会公布全国最佳饭店与餐厅名单。两份名单常常大相径庭,虽然从理论上来说应该完全一致。美国汽车协会采用“钻石”,莫比尔采用“星级”。两者对于饭店和餐厅的打分都采用1-5分制,对于每个分数的解释也大致相同。比如:美国汽车协会的一颗钻石意味着饭店或餐厅“清洁、安全、维修良好”;莫比尔的一星则表示“清洁、舒适、可靠”。美国汽车协会的五颗钻石意味着“出色、豪华,提供许多附加设施”;莫比尔的五星表
