C_(60)吲哚衍生物与对叔丁基杯[8]芳烃包合作用的热力学研究

用紫外光谱分析法,研究了对叔丁基杯[8]芳烃与C60-吲哚衍生物形成包合物的能力,测定了C60衍生物与杯[8]形成的包合物的形成常数、热力学函数ΔH和ΔS.结果表明:C60上取代基空间阻力使形成配合作用减弱,形成常数减小,焓值和熵值都正移.     

What Can We Learn from Art Practices? Exploring New Perspectives on Critical Engagement with Plurality and Difference in Community Art Education

The article presents a case of community art education in Leuven, Belgium. Participants who belong to disenfranchised groups of the local community were invited to engage in artistic actions and performances aiming at familiarising them with modern art practices. Such experiments are often disqualified as being irrelevant to the life‐conditions of these families in poverty, and hence as non‐emancipatory. In this article, the emancipatory quality of such initiatives is explored with reference to the art practices of the Belgian/Mexican artist Francis Alÿs and the reflections on emancipation by the French philosopher Jacques Rancière. These reflections help to shed a new light on the emancipatory dimension of community art practices and to consider theoretical concepts such as ‘poor pedagogy’.     

八级英语写作中如何写好激发句

八级英语写作教学中一般较注重立论句的写作技巧，但对激发读者阅读兴趣的激发句重视不够，缺乏对激发句写作技巧的研究和把握。激发句的写作应遵循二宝的原则，可采用开场白、叙述事件、提出问题等形式。     

Qualit?tsmanagementsysteme im Fachhochschulsektor

"Die Erhalter haben zur Leistungs- und Qualit?tssicherung ein eigenes Qualit?tsmanagementsystem aufzubauen", so bestimmt das ?sterreichische Fachhochschul-Studiengesetz. Neben den gleichfalls geregelten Ma?nahmen zur externen Qualit?tssicherung und -entwicklung, die durch einen eigenen Fachhochschulrat (FHR) administriert werden, müssen die ?sterreichischen Fachhochschulen daher Systeme des internen Qualit?tsmanagements entwickeln. 2006/2007 wurde der erreichte Sachstand erhoben und ausgewertet. Im Ergebnis lassen sich Erfolgs- und Misserfolgsfaktoren für die Einführungsphase von QM-Systemen formulieren.

The evolution of school league tables in England 1992–2016: ‘Contextual value‐added’, ‘expected progress’ and ‘progress 8’

Since 1992, the UK Government has published so‐called ‘school league tables’ summarising the average General Certificate of Secondary Education (GCSE) ‘attainment’ and ‘progress’ made by pupils in each state‐funded secondary school in England. While the headline measure of school attainment has remained the percentage of pupils achieving five or more good GCSEs, the headline measure of school progress has changed from ‘value‐added’ (2002–2005) to ‘contextual value‐added’ (2006–2010) to ‘expected progress’ (2011–2015) to ‘progress 8’ (2016–). This paper charts this evolution with a critical eye. First, we describe the headline measures of school progress. Second, we question the Government's justifications for scrapping contextual value‐added. Third, we argue that the current expected progress measure suffers from fundamental design flaws. Fourth, we examine the stability of school rankings across contextual value‐added and expected progress. Fifth, we discuss the extent to which progress 8 will address the weaknesses of expected progress. We conclude that all these progress measures and school league tables more generally should be viewed with far more scepticism and interpreted far more cautiously than they have often been to date.

有氧运动对人体细胞免疫功能影响的实验分析

应用实验室相关指标（细胞免疫功能）监测有氧运动对个体免疫力的影响,将36例乙型肝炎病毒核心抗体阳性的健康体检者平均分为有氧运动组和对照组,2年前后均采用化学发光法检测实验者的乙肝两对半模式、荧光定量PCR（FQ-PCR）仪测定其乙肝DNA水平和流式细胞仪检测CD4/CD8,得到有氧运动组乙肝两对半模式转为表面抗体阳性者显著高于对照组（P〈0.025）,其血清IgG、IgA含量也高于对照组,CD4/CD8的比值平均上调10.2%的结果,证明了有氧运动能明显提高个体的免疫力.

适度运动对摄入高能饲料大鼠T淋巴细胞亚群免疫的影响

以SD大鼠为实验动物,通过8 w的高能饲料摄入和4 w的运动锻炼后,检测其血清总蛋白、白蛋白含量,外周血CD3 细胞数量、CD4 、CD8 T细胞百分比的变化,来研究适度运动锻炼对高能饲料摄入动物免疫功能的影响。结果显示:适度运动锻炼明显提高CD3 T细胞数量,使CD4 T细胞百分比从55.2%-56.6%迅速上升到62.6%-63.0%,使高能饲料摄入组的CD8 T细胞百分比从56.2%极显著地下降到42.2%,从而使运动组的CD4 /CD8 的比值(1.49±0.10)显著高于对照组(1.01±0.07),表明适度运动锻炼具有显著促进正相免疫调节的作用。
