China Goes to Africa: a strategic move?

Entering the twenty-first century, particularly under the reign of Hu Jintao, China began to pursue an increasingly pro-active diplomacy in Africa. Most analysis on China's offensive diplomacy in Africa focuses on Beijing's thirst for energy and raw materials, and for economic profits and benefits. That is why it is often called ‘energy diplomacy’ or ‘economic diplomacy’ as if China, just like Japan in the 1980s, became another ‘economic animal’. But if one looks at the history of the PRC's foreign policy, Beijing has seldom pursued its diplomacy from purely economic considerations. Is this time any different? This article exams China's diplomacy in Africa from a strategic and political perspective such as its geo-strategic calculations, political and security ties with African countries, peacekeeping and anti-piracy efforts in the region, support for African regionalism, etc. It argues that China's diplomatic expansion in Africa, while partially driven by its need for economic growth, cannot be fully understood without taking into consideration its strategic impulse accompanying its accelerating emergence as a global power. Africa is one of China's diplomatic ‘new frontiers’ as exemplified by new Chinese leader Xi Jinping's maiden foreign trip to Africa in 2013.     

Media and Chinese Foreign Policy

In recent years, the relationship between the media and the foreign policy-making process in China has become more interactive and even a typical symbiosis. This paper attempts to conduct preliminary research on this very dynamic and changing relationship in the context of Sino–Japan relations. It argues that the Chinese media helps shape the agenda for foreign policy makers, narrow down the set of policy options, change the pace of policy making and implementation, and influence the direction of the final decision. Yet more often than not, the government still controls and regulates the reporting by the media on foreign policy issues. Once the media is perceived as going too far, the government never hesitates to rein it in through various internal and external mechanisms.     

Global Threats and American Strategies: From Communism in 1955 to Islamism in 2005

America's current security threats—the insurgency in Iraq, Islamic terrorism, and Iran's efforts to obtain nuclear weapons—seem strange and unprecedented. Parallels can be drawn, however, between the security threats of 2005 and those of fifty years ago. The U.S. foreign policy developed to confront the communist threat offers lessons as we develop strategies to combat today's threat. Two contemporary perspectives on strategic issues—one conservative/realist, one neoconservative/idealist—apply lessons of the Cold War to today's U.S. foreign policy, but each has serious flaws. A third, neorealist perspective, suggests that by leveraging the divisions already present in the Muslim world, the United States can win the global contest against Islamic terrorism. However, this would require a transformation in American strategy that will not be easily achieved.     

粪便DNA提取及检验

目的　研究人类粪便DNA的提取和检验方法。方法　 8人份粪便样本 ,磁珠法提取DNA后 ,进行STR复合扩增和mtDNAHVI区测序分析。结果　用 2种方法提取的粪便DNA ,STR复合扩增检验均未获成功 ;方法1提取的粪便DNA有 6个样本、方法 2有 7个样本获得了清晰可读的mtDNAHVI区序列 ,并与唾液对照样本DNA的序列完全一致。结论　用本文建立的方法提取粪便DNA ,不适于STR分析 ,可通过mtDNA测序分析进行检验。     

猪高脂血症心肌组织内皮素-1的表达

目的 探讨高脂血症对心肌组织内皮素-1(ET-1)表达的影响。方法 12头猪等分为高脂血症组与正常对照组，复制高脂血症动物模型后，用免疫组化3P法观察心肌组织内ET-1的表达情况，并用图像分析系统进行图像分析。结果 高脂血症组ET-1的表达明显高于正常对照组，差异显著(P＜0.001)。结论 高血脂容易诱导心肌组织ET-1的表达。     

道路交通事故颅脑损伤的法医学鉴定

目的　研究道路交通事故中颅脑损伤的类型、特点、主要并发症及其受伤人员的伤残评定。方法　 862例道路交通事故颅脑损伤的案例资料 ,按伤者受伤的不同部位、有无并发症、并发症的类型及伤残程度进行统计分析。结果　复合性颅脑损伤 2 76例 ,脑挫伤 192例 ,颅骨骨折 79例 ,颅内出血 91例 ,头皮外伤 2 2 4例 ;主要并发症为脑积水 ( 19例 ,2 2 0 % )、癫痫 ( 16例 ,1 86% )、偏瘫 ( 14例 ,1 62 % )、植物人状态 ( 12例 ,1 3 9% )。结论　道路交通事故中颅脑损伤 ,以头部复合性损伤最多见 ,严重的脑挫伤为最常见的损伤类型 ,并发症的诊断应掌握诊断标准 ,并注意与相关疾病鉴别。

从误划生熟谈侦查思维的模糊性

生熟属于对立关系 ,是对立的两极 ,之中的中介 ,有的清晰 ,有的模糊 ,而后者本文称之为生熟的模糊性。生熟这种模糊性决定了侦查思维应当具有一定的模糊性。在生熟不定的情况下 ,案件分析应为“偏生”。     

法庭语音学

本文对法庭语音学进行了研究综述,主要介绍了该学科的核心内容:说话人鉴定。在实际办案中,当未找到嫌疑人,只有犯罪分子的检材语音时,可以使用说话人画像/说话人分类技术。若没有犯罪分子的录音证据时,可以让受害人和证人进行说话人的听觉辨认。具体的辨认形式有两种:对熟人辨认和对陌生人辨认,在对陌生人辨认时可以采用语音辨认的方法进行。当检材语音和样本语音都齐备的时候,法庭语音分析专家就可以对二者进行比对检验了。目前语音比对分析涉及到的问题和领域有:基于贝叶斯方法的法庭推理和似然比计算、共振峰频率的测量应用、非解析感知与样例理论、法庭说话人自动识别以及不同方法的综合应用等。
