重新理解各种收入及其源泉——辨析"三位一体"公式的二重性

马克思以前的许多经济学家,例如斯密和萨伊,由于没有科学区分剩余价值的分配与剩余价值的生产之间的联系与区别,因而都无意或有意地混淆了收入分配与收入源泉两者之间的联系区别,"三位一体"公式就是这种混淆的理论表现形式.本文为了极其清晰地揭示出分配与生产关系之间的区别,力求全面、深刻地辨析"三位一体"公式的虚伪性和合理性,以便从整体上再现资本作为商品化经济或市场经济主体的复杂二重性质.在这里,唯物辩证的二重分析方法又成为解剖资本分配制度乃至运营制度、生产制度二重性的锐利武器.     

Amino acid formula as a new strategy for diagnosing cow’s milk allergy in infants: is it cost-effective?

Aims: To estimate the cost-effectiveness of a new strategy that uses an amino acid formula in the elimination diet of infants with suspected cow’s milk allergy (CMA).

Materials and methods: This pharmacoeconomic study was developed from the perspective of the Brazilian Public Healthcare System. The new strategy proposes using an amino acid formula in the diagnostic elimination diet of infants (≤24 months) with suspected CMA. The rationale is that infants who do not respond to the amino acid formula do not suffer from CMA. Patients with a positive oral challenge test receive a therapeutic elimination diet based on Brazilian Food Allergy Guidelines. This approach was compared to the current recommendations of the Brazilian Food Allergy Guidelines. A decision model was constructed using TreeAge Pro 2012 software. Model inputs were based on a literature review and the opinions of a panel of experts. A univariate sensitivity analysis of incremental cost-effectiveness ratios was performed.

Results: The mean cost per patient of the new amino acid formula strategy was R$3,341.57, while the cost of the current Brazilian guidelines strategy was R$3,641.08. The mean number of symptom-free days per patient, which was used as an indicator of effectiveness, was 900.6 and 875.7 days, respectively. The new strategy is, therefore, dominant. In the sensitivity analysis, the dominance was maintained with parameter variation.

Limitations: In the absence of information in the literature, some premises were defined by a panel of specialists.

Conclusions: The new strategy, which uses an amino acid formula in the elimination diagnostic diet followed by an oral food challenge, is a dominant pharmacoeconomic approach that has a lower cost and results in an increased number of symptom-free days.     

论时代潮流中的“戏曲程式”

中国的戏曲艺术博大精深、源远流长。如果说叙事抒情是戏曲艺术的表现目的,程式化的唱念做打,生旦净丑就是她的过程了。不管时代怎样发展,艺术表达形式如何变迁,程式都是构成戏曲的灵魂所在,没有程式就不成其为戏曲。本文将从戏剧艺术对生活之美的"夸张性放大"及其对"中国之美"的依托两个方面,探讨戏曲程式存在的必要性,并且分析在当前的艺术条件之下,戏曲艺术程式所面临的挑战及其原因。以期中国的传统艺术瑰宝———戏曲,能够更广泛的吸取时代的气息,在不改变立场的前提下,更广泛的深入大众、展现魅力,并且得以传承。     

AN EXACT FORMULA FOR DEFAULT SWAPTIONS’ PRICING IN THE SSRJD STOCHASTIC INTENSITY MODEL

We develop and test a fast and accurate semi‐analytical formula for single‐name default swaptions in the context of a shifted square root jump diffusion (SSRJD) default intensity model. The model can be calibrated to the CDS term structure and a few default swaptions, to price and hedge other credit derivatives consistently. We show with numerical experiments that the model implies plausible volatility smiles.

适宜集成的KHN滤波器设计

为了获得高精度的电压模KHN滤波器,以Deboo积分器为原型,先给出一种高精度、易集成的变形Deboo积分器,再借助Meson公式,用变形Deboo积分器设计出极点频率为31.8 kHz、品质因素为1、通带增益为2的通用电压模KHN滤波器.该电路不仅可同时实现高通、带通和低通输出,且极点频率与品质因素能实现正交、精确调节,电路的参数取决于电阻比,两积分电容接地,因而适合单片集成技术.计算机仿真结果与理论分析一致.     

On the complete monotonicity of the compound geometric convolution with applications in risk theory

We prove that the complete monotonicity is preserved under mixed geometric compounding, and hence show that the ruin probability, the Laplace transform of the ruin time, and the density of the tail of the joint distribution of ruin and the deficit at ruin in the Sparre Andersen model are completely monotone if the claim size distribution has a completely monotone density.
