2,3──二氨基吩嗪光谱特性研究及应用

研究了各种介质中不同酸度对2，3──二氨基吩嗪（DAP）的光谱特性的影响，发现非离子表面活性剂以及极性有机溶剂对其荧光具有强烈的增敏作用，荧光量子产率大大提高，而且强极性有机溶剂在无水环境下，对其荧光增敏比非离子表面活性剂更强。建立了有机介质和非离子表面活性剂介质荧光增敏的测定方法，并对各种介质增敏机理进行了讨论。

从1929看2009,经济危机下的中国电影

1929年的美国和2009年的中国都同样处在经济危机的寒潮之下,对比二者电影业的发展状况,分析经济危机对电影业产生的诸多影响,可以看出：首先,由于＂口红效应＂的影响,中美电影在经济危机中都出现了票房的大幅攀升,特别是中国电影增长迅速;其次,危机中的电影技术都得到了进一步的发展,如同1929年声音技术的运用一样,2009年的中国电影则是3D技术崭露头角,3D电影以及3D银幕的数量激增;再次,危机中电影内容普遍具有疗伤倾向,无论是当年美国盛行的歌舞片或是2009年中国主旋律电影的商业化,无一例外;最后,从娱乐产业的更迭趋势来看,1929年美国的百老汇逐渐衰落,电影逐渐取而代之。2009年的中国则是互联网迅速发展的一年,媒介融合趋势下电影的传播介质可能也会发生相应变化。     

Bringing the owners back in: An analysis of a 3-mode interlock network

This paper examines the association between ownership and director interlocks in Swedish big business during the period 1990–2005. By analyses of the 3-mode network of owners, firms, and directors, multiple director assignments are shown to be highly dependent on owner interlocks. The findings provide a new understanding of the mechanisms behind the formation of director interlocks. Furthermore, the association between the interlock types suggests that the ownership network may potentially (co-)produce some of the phenomena that have been attributed to the director network. Future analyses of director interlocks have to bring the owners back in.     

Sanctioning as a social norm: Expectations of non-strategic sanctioning in a public goods game experiment

Sanctioning increases cooperation in public goods games, but not indiscriminately under all conditions and in all societies, and the mechanisms by which sanctioning exercises its impact on behavior are yet to be studied in detail. We show experimentally that in the presence of sanctioning, our experimental subjects adjust their behavior in order to avoid being a free rider. They do this not only in the STANDARD sanctions treatment, where they directly experience any sanctions assigned to them, but also in our main treatment, the SECRET sanctions treatment, where no information on sanctions received is available until the end of the experiment. We observe no such free riding avoidance in the treatment without sanctioning. The mere knowledge that sanctions might be assigned increases cooperation among the members of our subject pool; subjects expect that non-strategic sanctioning occurs against the free riders. Moreover, these expectations are correct as we observe a similar pattern and extent of sanctioning in both treatments. We propose that sanctioning in itself is a social norm and may be culturally dependent, as suggested in the literature.     

THE CHOICE BETWEEN SETS OF REGRESSORS

This paper examines the choice of critical values for testing both non-sequential and nested sequential sets of constraints in the standard linear regression model. Modest increases in (e.g.) t-ratio critical values relative to their one-off values are often sufficient to maintain proper size. A Bayesian decision-theoretic approach, highlighted by the Schwarz (1978) criterion, provides a framework for deriving consistency and asymptotic local power properties of both forms of testing (data mining) algorithms.
