文化治理与社群自治——以网络耽美社群为例

国内学界通常将文化治理理解为国家主导的多元共治的管理模式。然而,在共治模式之外,还存在着社群自治模式。网络耽美社群通过构建社群共识、开展舆论监督和仲裁、协商道德准则等多种方式来维护社群的良性发展。网络耽美社群的自治模式,不仅揭示了新媒体时代中国社会日益复杂的权力分配格局,也为当代文化治理提供了一个有益的另类参考。中央高校基本科研业务费专项资金资助(0640-ZK1079);; 2015年度福建省社会科学规划项目资助(FJ2015B136

Flexible decapyrrylcorannulene hosts

球形笼状的富勒烯是上个世纪末最重要的科学发现之一，但对富勒烯的精确几何结构的认识却困难重重，原因是单晶中球形分子的取向往往是无序的，需通过笼外衍生或通过八乙基金属卟啉-富勒烯超分子主客体组装来固定富勒烯的取向，然后利用常用的单晶衍射分析技术来精确表征富勒烯的几何结构。然而许多富勒烯新结构因无法与卟啉主体形成高质量的单晶至今仍无法利用X射线衍射技术进行结构分析，直接制约了对富勒烯形成机理及结构-性能关系的深入认识。功能团簇材料创新研究群体的谢素原、张前炎课题组另辟蹊径地从曲面结构的十氯碗烯C20Cl10出发，合成了十吡咯取代的碗烯分子C20(C4H4N)10。结构分析表明该分子的结构特征是碗烯的碳框架与十个吡咯基团通过单键相连。实验还证明，用甲基去取代吡咯3, 4-位置的氢并不利于富勒烯与碗烯衍生物形成有序的超分子组装体，理论研究进一步诠释了十个吡咯‘手指’的集体贡献比单个碗烯‘手掌’更大的原因。该研究工作是功能团簇材料创新研究群体长期积累，并由校内外十多位研究人员共同努力完成。徐云彦（2014级硕士生）、田寒蕊（2014级博士生）和李姝慧（2016年进站博士后）为该论文共同第一作者。【Abstract】The assembly of spherical fullerenes, or buckyballs, into single crystals for crystallographic identification often suffers from disordered arrangement. Here we show a chiral configuration of decapyrrylcorannulene that has a concave ‘palm’ of corannulene and ten flexible electron-rich pyrryl group ‘fingers’ to mimic the smart molecular ‘hands’ for self-adaptably cradling various buckyballs in a (+)hand-ball-hand(−) mode. As exemplified by crystallographic identification of 15 buckyball structures representing pristine, exohedral, endohedral, dimeric and hetero-derivatization, the pyrryl groups twist with varying dihedral angles to adjust the interaction between decapyrrylcorannulene and fullerene. The self-adaptable electron-rich pyrryl groups, susceptible to methylation, are theoretically revealed to contribute more than the bowl-shaped palm of the corannulene in holding buckyball structures. The generality of the present decapyrrylcorannulene host with flexible pyrryl groups facilitates the visualization of numerous unknown/unsolved fullerenes by crystallography and the assembly of the otherwise close-packed spherical fullerenes into two-dimensional layered structures by intercalation.This research was supported by the National Natural Science Foundation of China (21771152, 21721001, 21827801, 51572231, 51572254, 21571151, 2170010228), the 973 Program of China (2014CB845601 and 2015CB932301), the China Postdoctoral Science Foundation (2016M602067), the National Key Research and Development Program of China (2017YFA0402800), and the Fundamental Research Funds for the Central Uni- versities (20720170028, 20720160084).

An Analysis of Influence Factors on Rural Labor's Cross-border Employment——Based on a case study about T-village in Puyang city of Henan province

随着工业化和城市化的快速发展,农村劳动力向非农产业转移成为必然趋势,在工业化和城市化初期,就地转移和向城市转移是主要转移方式。但是,随着全球化的发展和城市吸纳就业能力的下降,对外劳务输出逐渐成为我国农村劳动力向外转移的“第三条道路“。本文以河南省濮阳市的T村为个案,利用劳动力迁移理论,探讨了农业大省农村劳动力跨境就业的影响因素,并以此为基础提出了相关政策建议。With the rapid development of industrialization and urbanization,the rural labors transfer| into non-agricultural in-dustries is an inevitable trend,in the initial stage,situ metastasis and migration to the town are the main ways.As the global-ization and decreasing of the urban ability to absorb employment,going abroad becomes the third-way for China’s rural labor.This article takes T village in Puyang city of Henan province for a case and uses the Labor migration theories to discuss the factors that influence the rural labor migration,and gives some policy recommendations on the basis of analysis.教育部“新世纪优秀人才支持计划”资助;国家社会科学基金项目(项目编号:07BSH034)支

Protective effects of maternal mindfulness on social withdrawal in young children

目的:探讨母亲正念对幼儿社交退缩行为的保护作用,以及正念养育、亲子关系和幼儿趋避气质在其间可能的中介作用和调节作用。方法:选取幼儿母亲605人,采用正念注意觉知量表(MAAS)、儿童社会偏好量表(CSPS)、正念养育量表(IM-P)、亲子关系量表(CPRS)、儿童气质问卷(PTQ)分别对母亲正念、社交退缩、正念养育、亲子关系、趋避气质进行评估。结果:幼儿CSPS得分与MAAS、IM-P、CPRS和PTQ得分均呈负相关(r=-0.65～-0.16,均P&lt;0.01);IM-P和CPRS得分在MAAS与CSPS得分之间起链式中介作用(&beta;=-0.05,P&lt;0.01),CPRS得分在MAAS与CSPS得分之间起部分中介作用(&beta;=-0.04,P&lt;0.01);PTQ得分在MAAS和IM-P得分的关系中起调节作用(&beta;=0.11,P&lt;0.01)。结论:母亲正念不仅直接作用于社交退缩,还通过正念养育、亲子关系间接作用于社交退缩,趋避气质可调节母亲正念与正念养育之间的关系。</p

This bibliography concerning research on agriculture and development was compiled at the request of the national information and documentation services of the Dominican Republic. Together with the bibliography on Haiti, it comes as a follow-up to a series of nine bibliographies on agricultural research in Southern African countries, compiled and published between 1990 and 1992 in collaboration with the Southern African Centre for Cooperation in Agricultural Research (SACCAR). The main purpose of these bibliographies is to provide a working tool for exploiting the national documentary heritage by bringing together information on agricultural and rural development, both past and present. The bibliographies are a means of promoting rapid and continuous interchange and use of research results in ACP countries. Researchers in national stations can use them to focus and plan their activities. Although the main focus of these bibliographies is on agricultural research, they cover a wider spectrum of subjects in development, including health, socio-economics and gender issues.

山西省虹鳟鱼弧菌病病原菌的分离与鉴定

1985年6～9月间,山西省虹鳟鱼实验场鱼种爆发了一起细菌性疾病,从病鱼的肝、脾、肾中分离到细菌,用此菌人工感染虹鳟能得到与天然发病病鱼相似的症状,并从被感染鱼的体内重新分离到这种菌,证实为该病病原菌。经鉴定为鳗弧菌生物变种Ⅲ(V.anguillarum biovarⅢ,biovar nov)隶属于弧菌Ⅰ组中的淡水亚组弧菌

弧菌Ⅰ组中淡水亚组弧菌引起的虹鳟鱼病

于1985&mdash;1986年,以山西省虹鳟鱼实验场的虹鳟病鱼(7&mdash;12cm)为材料,进行鱼病研究。从病鱼肝、脾、肾中分离出致病细菌,经分类鉴定为鳗弧菌生物变种Ⅲ(新生物变种),隶属于弧菌Ⅰ组中的淡水亚组弧菌。对该菌进行的药物筛选的抑菌试验表明:62.5&mu;g/L的强力霉素和100&mu;g/L的鱼安(主要成分为氯代脲酸)有效,同时结合采用井水温度低于自流泉水的措施,此病可得到控制
