我国规模化肉牛场牛病毒性腹泻-粘膜病流行状况监测   总被引:2,自引:0,他引:2  
从山东、河南和河北省的6个规模化肉牛场随机采肉牛血清89份,直肠粪拭子165份,分别用微量细胞中和试验和双抗体夹心ELISA试剂盒检测牛病毒性腹泻粘膜病(BVDMD)的抗体和抗原。诊断结果:BVDMD中和抗体阳性率为46.2%~65.0%;BVDMD病毒抗原阳性检出率为5.1%~77.2%。从而证实我国中原地区肉牛群中存在有BVDMD。  相似文献

新冠肺炎疫情作为当今世界面临的最严峻的全球性问题,其应对最有效的路径仍是全球治理。危机之下人类社会的存续需要超越私利实现国家间共生。相对于西方传统的全球治理理念,中国方案基于对疫情下全球化时代的共生性判读,明确了推动构建命运共同体的共生型全球治理目标,推动全球治理转型从消极共生向积极共生实现结构优化。然而,依靠共生自身升级的滞缓性与现实需求的迫切性之间存在矛盾,"共生"在资源分配、认同建构以及合作实现等方面并不具备必然性,无法为现实问题的解决提供普遍化的标杆与规范,需要借助"共享"的理念工具进行有效助推。具体来说,就是以共生关系的主体性、共生纽带以及共生底线为出发,从资源配置的优化、主体认同的强化以及和谐包容的价值引领三方面着手,将共享理念融入到人类命运共同体的建构中,并通过中国对全球治理转型的过程参与,有效实现共享从理念引领到现实助推的功能转换,为新型的共生型全球治理模式的良性运作提供助力。  相似文献

The Victorian periodical press offers unique insights into many diverse areas of nineteenth-century experience, and the complex relations between gender, science and culture in particular, yet it has been consistently marginalized as a primary resource in academic study. The Science in the Nineteenth-century Periodical (SciPer) project at the universities of Sheffield and Leeds is creating a new point of access to a wide range of non-specialist periodicals across the century by means of a fully searchable electronic index. By detailing the entire contents of each journal, and not just those articles that have a clear scientific relevance, it becomes clear that science formed a fundamental and integral part of nineteenth-century culture. The electronic index, moreover, will include hypertext cross-reference links that will allow the user to identify a dialogic pattern of encounters between ostensibly diverse articles, rather than only to browse in a simple chronological mode. By adopting this innovative approach, the SciPer database will reveal the manifold intertextual relations between the fictional works of women writers like Elizabeth Gaskell and the scientific articles that often appeared in the pages of the same magazines, and will show that writers of both sexes and across several different genres actively engaged in vibrant interdisciplinary debates concerning scientific issues in a forum provided by the periodical. Although the SciPer database itself is not specifically focused on issues of gender, the index will include several periodicals aimed explicitly at a female readership and, by providing access to titles still rarely utilized in modern scholarship, it will offer further insights into the important contemporary debates about women and science, as well as the more subtle ways, in which gendered imagery was employed within scientific discourse. This article details some critical findings from Punch , The English Womans Domestic Magazine , Cornhill Magazine and the Review of Reviews .  相似文献

Do online and offline voters differ in terms of policy preferences? The growth of Internet voting in recent years has opened up new channels of participation. Whether or not political outcomes change as a consequence of new modes of voting is an open question. Here we analyze all the votes cast both offline (n = 5.7 million) and online (n = 1.3 million) and compare the actual vote choices in a public policy referendum, the world's largest participatory budgeting process, in Rio Grande do Sul in June 2014. In addition to examining aggregate outcomes, we also conducted two surveys to better understand the demographic profiles of who chooses to vote online and offline. We find that policy preferences of online and offline voters are no different, even though our data suggest important demographic differences between offline and online voters.  相似文献

十八届三中全会审议通过的《中共中央关于全面深化改革若干重大问题的决定》提出:"推动省以下地方法院、检察院人财物统一管理,探索建立与行政区划适当分离的司法管辖制度,保证国家法律统一正确实施。"之后,探索建立与行政区划相分离的司法管辖制度受到社会公众广泛热议。以美国法院和我国海事法院体制为分析视角,就如何建立与行政区划相分离的司法管辖制度进行探索,并在制度设计上提出一些构想。  相似文献

Surprising correspondences emerge from the parallel investigation of fund accounting practices in Italian entities until the late nineteenth century and in the contemporary U.S. public sector. The analysis attempts to interpret similarities and differences in light of dissimilar environmental features, and wonders if the Italian tradition could have some explanatory capability on the U.S. present standards. The “fund” concept and its use are strictly similar; they are founded on information needs for governance and internal control. Contemporary requirements for democracy and transparency, and opportunities coming from modern ICT tools bring U.S. organizations to be accountable to the citizenry.  相似文献

A genealogy of the radical ideas that underline al-Qaeda"s justification for violence shows that the development of jihadi thought over the past several decades is characterized by the erosion of critical constraints used to limit warfare and violence in classical Islam. This erosion is illustrated by the evolution of jihadi arguments related to apostasy and waging jihad at home, global jihad, civilian targeting, and suicide bombings.  相似文献

Abstract

Socioeconomic data supplied by the FBI on the backgrounds of 280 known right‐ and left‐wing terrorists active in the United States during the late 1960s and early 1970s was tabulated. Isolating for right‐left affiliation, membership status, and gender, seven variables were examined and used to confirm prevailing assumptions regarding the socioeconomic status of right‐ versus left‐wing terrorists active during this period. Findings support clear socioeconomic differences between right‐wing and left‐wing terrorists and emphasize the dominant position of women within left‐wing organizations. Surprising evidence revealed that considerable class differences exist within right‐wing groups between rank‐and‐file members and the leadership core.  相似文献
