转变期青花瓷艺术空前繁荣的原因

明末清初[明万历三十六年（1608）至康熙二十年（1681）]的青花瓷艺术没有因御窑停烧和战乱而衰败,相反,出现了空前繁荣的局面,展现了独特的时代特征和风貌.陶瓷学界称这个时期为中国瓷器发展的转变期.由于晚明商品经济的发展,思想观念的解放,御窑与民窑的融合和互动,以及科技的发展,使瓷器在构图风格、造型技法、纹饰绘画、审美观念等方面都有极可贵的创新和发展.     

Assessing the High Representative’s Role in Egypt during the Arab Spring

The 2009 Lisbon Treaty institutionalised an intergovernmental constitution for managing policies traditionally a matter of national sovereignty, such as foreign and defence policies. However, important innovations were introduced in the foreign policymaking structure to limit its intergovernmental logic, in particular, with regard to the role of the High Representative (HR). It was generally assumed that those innovations would have made development of a coherent EU foreign policy possible. Yet, in one of the most significant tests for the EU’s foreign and defence policies in the post-Lisbon era, namely the Egyptian crisis (2011-14), those reforms did not work as expected. Notwithstanding the innovations, the HR’s role was diminished by the European Council’s strict control over foreign policy toward Egypt. The lack of clear policy guidelines towards the issue of democratisation in the Arab world in the 2003 European Security Strategy, although partially mitigated by the European Neighbourhood Policy and the Barcelona Process/Union for the Mediterranean, made it even more difficult for the HR to bring a European perspective into the largely intergovernmental setting.     

The global political economy of climate change,agriculture and food systems

The food and agriculture sector is both a major contributor to climate change and especially vulnerable to its worst impacts. This means that much is at stake in what is a complex set of contested political dynamics as new governance agendas are rolled out. On one hand, there is a strong push for ‘climate-smart agriculture’ (CSA) and related initiatives in the area of marine resources such as the idea of the blue economy, as an attempt to bring a range of viewpoints together to address the interrelationship between these ecological and economic systems. On the other hand, critics see these strategies as promotion of more of the same kinds of policies that created stress in the climate–food system in the first place. To unpack these issues, this special forum brings together a collection of papers that highlight three overlapping themes that lie at the centre of these debates, yet which have not been fully acknowledged by those implementing CSA initiatives: the role of power and interests in shaping governance approaches to climate and food systems; the ways in which existing approaches, primarily those promoting open markets and technology, are reinforced in governance initiatives; and the sidelining of questions of inequality.     

Comparison of Four Saliva Detection Methods to Identify Expectorated Blood Spatter

Blood spatter analysis is an important step for crime scene reconstruction. The presence of saliva in blood spatter could indicate expectorated blood which is difficult to distinguish from impact spatter. In this study, four saliva test methods (SALIgAE^®, Phadebas^® sheet, RSID^™-Saliva kit, and starch gel diffusion) were compared to identify the best method for detecting expectorated blood spatter. The RSID^™-Saliva kit showed the highest sensitivity even when saliva was mixed with blood, and was not inhibited by the presence of blood. The SALIgAE^® test provided easy and rapid results, but the yellow color of a positive reaction was overwhelmed by the red color of the blood. The starch gel diffusion method and the Phadebas^® sheet exhibited relatively low sensitivity and the assay took a long time. When using the RSID^™-Saliva kit for identifying saliva in blood, results should be read within 10 min.     

紫外-可见光谱法研究蓝色圆珠笔色痕自然老化规律

目的论述自然老化下蓝色圆珠笔色痕中染料成分的变化规律。方法利用UV-VIS光谱对圆珠笔文字色痕中染料成分相对于铜酞菁的变化进行实验。结果得到染料与铜酞菁吸光度之比随老化时间变化的数据和曲线。结论利用UV-Vis光谱研究文件制成时间是可行的,为书写时间的鉴定拓展了思路。     

乌拉圭回合《农业协议》国内支持条款缺陷问题研究

乌拉圭回合《农业协议》实现了农产品到多边贸易体制的回归,但协议并不是对国际农产品贸易的永久性安排,各成员仍有义务通过后续谈判,不断提高国际市场农产品贸易自由化水平直至完全实现自由化。因此,研究《农业协议》国内支持条款的局限性与执行中存在的问题,分析新一轮农产品多边谈判中应修正的问题,对于我国实施国内支持条款和参加新一轮农业多边谈判,具有理论和实践意义。     

Applications of Blue Light‐curing Acrylic Resin to Forensic Sample Preparation and Microtomy

This study discusses the results of an evaluation of a one‐part blue light‐curing acrylic resin for embedding trace evidence prior to the preparation of thin sections with a microtome. Through a comparison to several epoxy resins, the physical properties relevant to both trace evidence examination and analytical microscopy in general, including as viscosity, clarity, color, hardness, and cure speed, were explored. Finally, thin sections from paint samples embedded in this acrylic resin were evaluated to determine if, through smearing or impregnation, the resin contributed to the infrared spectra. The results of this study show that blue light‐curing acrylic resins provide the desired properties of an embedding medium, generate high‐quality thin sections, and can significantly simplify the preparation of paint chips, fibers and a multitude of other types of microscopic samples in the forensic trace evidence laboratory.     

3种甲苯胺蓝异染肥大细胞方法的比较

目的比较3种甲苯胺蓝异染肥大细胞方法的应用性。方法采用甲苯胺蓝水溶液与高锰酸钾配比染色（方法一）、甲苯胺蓝酒精溶液和氯化钠溶液配比（方法二）、甲苯胺蓝水溶液染色、冰醋酸分色（方法三）3种方法对人和小鼠肺组织冰冻切片进行染色,比较染色结果、并评价方法稳定性及实用性。结果方法一染色肺组织切片,结果切片蓝色背景清晰,肥大细胞胞质内紫红色颗粒鲜明,与背景蓝色对比度高,易辨识,且多次重复染色效果稳定;方法二及方法三肺组织的蓝染背景、和肥大细胞胞浆颗粒的紫红色染之间的对比度均不及方法一清晰,稳定性亦次之。结论甲苯胺蓝水溶液与高锰酸钾配比染色法异染肺组织冰冻切片,结果清晰、操作简便且稳定性好,适合在相关检验中选用。

目的考察圆珠笔墨迹中碱性蓝7及其去乙基产物的降解变化,为圆珠笔墨迹书写时间的研究提供基础数据。方法用氙灯老化碱性蓝7以生成其5个去乙基产物。建立LC-MS/MS检测碱性蓝7及其去乙基产物的方法。制作圆珠笔墨迹样本,在室内自然光照条件下老化3个月,同时进行控制实验条件的氙灯老化和高温老化实验。结果碱性蓝7的相对含量持续下降,其第一、第二级去乙基产物E4、E3的相对含量相继达到最大值,剩余三个去乙基产物E2、E1和E0的相对含量在三个月内持续增加。结论碱性蓝7的相对含量与光的辐照能量呈指数函数关系,其去乙基产物E4、E3的相对含量与光的辐照能量呈二次函数关系。不同油墨中碱性蓝7的老化曲线不同。温度对碱性蓝7的降解基本没有影响。     

To What Extent Can the January 25 Revolution Be Seen as a “Bifurcation” in the Life Stories of Egyptian Migrants in France?

ABSTRACT

The revolutionary process initiated in Egypt in 2011 triggered a surge in Egyptian-led organizations in the public arena in Paris. This article examines the issue of the “biographical impacts of commitment” and applies the “life history approach” to these Egyptian activists. Our basic hypothesis is that the opening up of political perspectives in Egypt may be understood as a bifurcation process in such individual trajectories. It may have entailed a series of disruptions in everyday life to the extent of causing these Egyptian migrants to reconsider their positions within the French context.
