HPLC测定复方丹皮酚凝胶中丹皮酚含量

目的:建立复方丹皮酚凝胶中丹皮酚的含量测定方法.方法:采用高效液相色谱法,色谱柱为SHIMADZU VP-ODS(4.6 mm×150 mm, μm),流动相为甲醇-水(50∶50),检测波长为274 nm.结果:丹皮酚进样量为0.05～0.30 μg时呈良好的线性关系(r =0.999 8).平均回收率为100%,SD为0.87%(n =5).结论:PLC法可用于复方丹皮酚凝胶的质量控制.     

首都大学生基层志愿者服务团项目绩效评估报告

通过评估首都大学生基层志愿者服务项目的适当性、效率、效果、受益群体满意度、社会影响和持续性等项目,评估发现,基层服务团项目在运作中志愿者的素质与基层单位的岗位需求不匹配,缺乏畅通、全方位的信息沟通渠道等问题。因此,我们必须扩大宣传力度,储备优秀的志愿者人才,完善志愿者管理体制及相关制度,推动首都大学生基层志愿者服务团项目进一步发展。

干部实绩考核方法论探析

凭实绩用干部是新时期新阶段干部原则的创造性发展.贯彻凭实绩用干部的原则,必须坚持马克思主义的世界观和方法论,用科学的方法考核干部的实绩,正确处理干部的物质文明建设成果与精神文明建设成果、个人实绩与集体实绩、现实成果与长远发展潜力、客观条件与主观努力等一系列关系,使实绩考核科学地引导和激励干部,在干部管理中发挥更加积极的作用.     

违约责任与风险负担

风险负担与违约责任是共同处理标的物毁损灭失案型的两项不同制度。在我国违约责任的归责原则实现了由过错责任向严格责任转化的情况下,风险负担制度的内涵与适用范围应作相应的调整。违约之际风险负担的处理涉及到这两项制度的协调与配合的复杂关系。在履行迟延期间标的物毁灭时,原则上应使违约方当事人承担风险。对质的不完全履行之际的风险负担问题,国际公约、各国或各地区立法不一,对我国现行法律进行体系解释可知,当买受人拒绝接受标的物或者解除合同的,由出卖人承担风险,否则则由买受人承担风险,不过,买受人仍享有违约救济权。在违约之际的风险负担问题上,我国现行法律还存在若干漏洞,应予填补。     

《著作权法》修改:关键条款的解读与分析(下)

修改后的《著作权法》将视听作品分为"电影作品、电视剧作品及其他视听作品",并分别规定了不同的著作权归属规则,但两类视听作品分类标准不明,且对其他视听作品采用约定优先的著作权归属规则,不利于此类视听作品的许可与传播。当一名合作作者无正当理由反对对合作作品的特定利用时,其他合作作者不能发放专有许可,这可能给合作创作的学术论文和专著的出版带来负面影响。修改后的著作权法将电台、电视台和报刊通讯社员工的职务作品定为特殊职务作品,可能产生其员工离职后无法获得出版其职务作品文集所须授权的问题。新增的有关职务表演的规定合理地解决了长期以来将"演出单位"作为"表演者"的问题。对传播录音制品获酬权的规定并不是法定许可,因为《著作权法》并没有为录音制作者规定除信息网络传播权之外的传播权专有权利。修改后的《著作权法》的一大亮点是将广播组织的转播权以技术中立的方式拓展至网络环境。有关用作者的署名推定权利存在的规定,被诉侵权人应证明其使用涉案作品已获许可的规定,以及法院有权没收和销毁侵权复制品的规定,均直接来源于《中美经济贸易协定》,其中有些仅具有形式意义。修改后的《著作权法》为摄影作品享受新的保护期(作者有生之年加50年)所设定的条件与《世界知识产权组织版权条约》不一致,可能需要再次修改。     

县域政府治理绩效的实证研究：公众满意度的视角--基于佛山市 A 区的治理实践

以佛山市 A 区为个案,对如何测量中国县（区）层级的政府治理绩效进行实证探索。在借鉴世界治理指标（WGI)的基础上,构建了一个本土化的地方政府治理绩效指标体系,对 A 区政府的治理绩效水平进行量化评估,并且通过构建一个多元回归模型深入挖掘影响其总体治理水平的相关因素。结果表明：公众对于 A 区政府的总体治理水平处于“一般”到“比较满意”之间;在六个维度的治理绩效中,公众满意度最低的是“腐败控制”和“法治”,最高的是“政府稳定和暴力避免”和“政府有效性”;除了“管制质量”和“政府稳定与暴力避免”之外,其他四个维度的治理绩效对 A 区政府的总体治理水平都具有显著影响,其中,“政府有效性”对总体治理水平的影响最大。     

State as resource,mediator and performer: understanding the local and global politics of gold mining in Kyrgyzstan

The inability of the state to maintain security and the rule of law for the purposes of foreign direct investment and industrial production is often taken as a sign of its weakness. However, such judgments say little about the actual functions of the state for global extraction industries and local political forces which demand their share of the pie. Whilst coercive state power may have decreased since Kyrgyzstan became independent, more important is the fact that the state itself has been transformed under the ruptures of, on the one hand, economic and political liberalization and, on the other, the effects of so-called ‘revolutions' of 2005 and 2010 which led to the wholesale restructuring of national structures of clientelism. Based on ethnographic research conducted in Talas province, documentary sources and interviews with gold mining companies and state officials, the paper investigates the state's shifting roles with respect to Kyrgyzstan's gold mining sector. Firstly, it explores the state as a source of rents for officials who grant and rescind licences in exchange for formal and informal payments from foreign investors, often via offshore vehicles. Secondly, it considers the role of the state as mediator between foreign investors and their access to sites. Finally, it identifies the state as performer of its status as sovereign power despite its inability to prevent uprisings and actually guarantee the promised access to its territory.     

Global Astana: nation branding as a legitimization tool for authoritarian regimes

This paper examines how, in post-Soviet Kazakhstan, both channels of elite and banal nationalism (such as sports and higher education) serve as instruments to promote the country. Through these channels, Kazakhstan is portrayed as an open, dynamic and successful country, an image which is in serious disjuncture with the authoritarian nature of the regime. Taking advantage of massive oil revenues, the government organized a significant OSCE general conference in 2010, while chairing the institution. In addition, it created the Astana professional cycling team, which rapidly became a world leader in the sport. Last but not least, Nazarbayev University, attracting prominent Western scholars, is now designed to make the country compete in the international arena of academic rankings. Domestic and international performances are thus treated as instruments to promote the legitimacy of the state at national and global levels. But this would not be possible without the help of individual actors who actively participate in this process. A close investigation shows that their social capital is based on global connections in various spheres (sports, finance and academia). This paper draws on evidence gathered through qualitative methods of enquiry (participant observation and semi-structured interviews). Finally, Astana is treated as a Latourian actor-network that has its own life and agency, thanks to the global association of various human actors and material objects.
