AIM: To determine whether the combination of platelet count(PLT) with spleen volume parameters and right liver volume(RV) measured by magnetic resonance imaging(MRI) could predict the Child-Pugh class of liver cirrhosis and esophageal varices(EV).METHODS: Two hundred and five cirrhotic patients with hepatitis B and 40 healthy volunteers underwent abdominal triphasic-enhancement MRI and laboratory examination of PLT in 109/L. Cirrhotic patients underwent endoscopy for detecting EV. Spleen maximal width(W), thickness(T) and length(L) in mm together with spleen volume(SV) and RV in mm3 were measured by MRI, and spleen volume index(SI) in mm3 was obtained by W × T × L. SV/PLT, SI/PLT and RV × PLT/SV(RVPS) were calculated and statistically analyzed to assess cirrhosis and ***: SV/PLT(r = 0.676) and SI/PLT(r = 0.707) increased, and PLT(r =-0.626) and RVPS(r =-0.802) decreased with the progress of Child-Pugh class(P < 0.001 for all). All parameters could determine the presence of cirrhosis, distinguish between each class of Child-Pugh class, and identify the presence of EV [the areas under the curve(AUCs) = 0.661-0.973]. A m o n g p a ra m e t e r s, R V P S c o u l d b e s t d e t e r m i n e presence and each class of cirrhosis with AUCs of 0.973 and 0.740-0.853, respectively; and SV/PLT could best identify EV with an AUC of ***: The combination of PLT with SV and RV could predict Child-Pugh class of liver cirrhosis and identify the presence of esophageal varices.

For lifetime non-smokers, lung cancer risk is mainly associated with inhalation exposure to air pollution. For the Chinese population, indoor air pollution due to solid fuel combustion has been the primary source of inhalation exposure for decades. Polycyclic aromatic hydrocarbons （PAHs） are the by-products of incomplete combustion.

This paper presents a nonlinear multidimensional scaling model, called kernelized fourth quantifica- tion theory, which is an integration of kernel techniques and the fourth quantification theory. The model can deal with the problem of mineral prediction without defining a training area. In mineral target prediction, the pre-defined statistical cells, such as grid cells, can be implicitly transformed using kernel techniques from input space to a high-dimensional feature space, where the nonlinearly separable clusters in the input space are ex- pected to be linearly separable. Then, the transformed cells in the feature space are mapped by the fourth quan- tifieation theory onto a low-dimensional scaling space, where the sealed cells can be visually clustered according to their spatial locations. At the same time, those cells, which are far away from the cluster center of the majority of the sealed cells, are recognized as anomaly cells. Finally, whether the anomaly cells can serve as mineral potential target cells can be tested by spatially superimposing the known mineral occurrences onto the anomaly ceils. A case study shows that nearly all the known mineral occurrences spatially coincide with the anomaly cells with nearly the smallest scaled coordinates in one-dimensional sealing space. In the case study, the mineral target cells delineated by the new model are similar to those predicted by the well-known WofE model.

代理理论(agency theory,AT)因其简洁性被广泛接受并大量使用,然而AT提出降低代理成本的机制未获一致支持,引发了争议.为解决刚性假设的不足,行为代理理论(behavioral agency theory,BAT)从认知视角对AT中理想化的风险假设做出修正,将治理手段、问题界定与决策相结合.在分析AT降低代理成本机制失效原因后,BAT通过引入个体认知系统地描绘了行为决策的逻辑基础.与此同时,BAT刻画了代理人因面临内部治理和外部因素而承担风险的“内心活动”为战略和治理研究提供了新颖的行为学视角,提高了理论预测性,这尤其适于研究因制度、文化等区别导致的中国公司治理差异.相比于欧美研究,国内学者对该理论关注较少,缺乏系统性理论述评,应用上也存在巨大空白.因此,本文首先梳理了BAT的理论起源并界定了理论核心问题;随后根据理论框架从问题界定、薪酬激励、监督机制、家族企业研究这4个主题进行述评,并理清研究边界;最后,本文提出关于未来研究方向和理论如何配适中国情境的建议,以期为后来研究提供借鉴.
