加缪“荒诞人”的非本真生存

荒诞人是阿尔贝.加缪在荒诞理论中描述的重要概念,也是他探索人生存方式的鲜活载体。针对荒诞人在操作层面的反抗、激情和自由分析得出荒诞人的生活追求是非本真生存的再现,并和加缪在《局外人》中塑造的局外人的本真生存形成鲜明的对比。     

β-环糊精修饰区带毛细管电泳法测定野菊花中的刺槐素、木犀草素和槲皮素

野菊花是菊科植物野菊(Chrysanthem indicumL.)的干燥头状花序,具有清热解毒、降血压等功效[1],药理作用有抗毒、改善血液循环、抑制血小板聚集和增强吞噬细胞等功能[2],临床将野菊花浸膏制成栓剂,对慢性盆腔炎、宫颈糜烂、慢性前列腺炎等有显著疗效[3]。野菊花的主要有效成分为黄酮类化合物,准确测定野菊花中的黄酮类化合物对于其质量控制和确保疗效具有重要的意义。毛细管电泳法是20世纪80年发展起来的一种新的分离分析新方法,具有分析速度快、分离效率高、样品和溶剂消耗量小、毛细管柱寿命长和容易清洗等优点,已经被广泛用于中草药成分…     

沙芥罐头加工技术研究

对沙芥罐头加工技术进行了研究。结果表明,一定浓度的铜离子可达到较好的护绿效果;在汤料中加入糖和香味物质、降低汤液的pH值、采用常温杀菌工艺能达到商业杀菌要求。在室温下可贮藏6个月,保持绿色不褪,感官质量也得到改善。     

试析阿尔都塞的“症候阅读”

“症候阅读”与意识形态、文本结构及总问题存在着复杂的逻辑关联。意识形态是症候阅读的根源,它决定了文本的结构以及思想理论的总问题,所以,虽然文本结构是症候阅读的直接对象,但症候阅读的关键是要抓住潜藏着的总问题。对症候阅读的内在含义的分析也表明,症候阅读的实质就是总问题的阅读。     

柿子后熟过程中呼吸动态和内源乙烯浓度变化的研究

利用乙烯利和硫代硫酸银处理不同品种柿子研究柿果采后过程中呼吸动态和内部乙烯浓度的关系。结果表明,2个柿品种虽在采后生理生化方面存在某些差异,但均属于呼吸跃变型果实。伴随跃变的发生,糖酵解—三羧酸循环途径所占比例逐渐增加,磷酸戊糖途径所占比例逐渐降低。在电子传递过程中,细胞色素途径占优势,剩余呼吸也占相当大的比例,但未测出抗氰的交替途径的运行量。乙烯利处理可明显提高果实内部乙烯浓度,促进呼吸跃变,而硫代硫酸银处理则相反。可以利用化学药剂来调控柿果的成熟过程。     

A nonparametric repeated significance test with adaptive target sample size

In this article a general result is derived that, along with a functional central limit theorem for a sequence of statistics, can be employed in developing a nonparametric repeated significance test with adaptive target sample size. This method is used in deriving a repeated significance test with adaptive target sample size for the shift model. The repeated significance test is based on a functional central limit theorem for a sequence of partial sums of truncated observations. Based on numerical results presented in this article one can conclude that this nonparametric sequential test performs quite well.     

“动词＋到L”的“把”字句论析

重点讨论了“到L”处在动词之后的“把”字句，从三个不同的角度分析了此类“把”字句的位移类型，认为虽然每一具体句子的位移情况都可以从三个方面来考察，但共现的具体小类有差别，这是因为不同的位移类型与动词的语义特征和类之间存在着相互制约的关系。     

Sensitivity Analysis for Critical Control Points Determination and Uncertainty Analysis to Link FSO and Process Criteria: Application to Listeria monocytogenes in Soft Cheese Made from Pasteurized Milk

Microbiological food safety is an important economic and health issue in the context of globalization and presents food business operators with new challenges in providing safe foods. The hazard analysis and critical control point approach involve identifying the main steps in food processing and the physical and chemical parameters that have an impact on the safety of foods. In the risk‐based approach, as defined in the Codex Alimentarius, controlling these parameters in such a way that the final products meet a food safety objective (FSO), fixed by the competent authorities, is a big challenge and of great interest to the food business operators. Process risk models, issued from the quantitative microbiological risk assessment framework, provide useful tools in this respect. We propose a methodology, called multivariate factor mapping (MFM), for establishing a link between process parameters and compliance with a FSO. For a stochastic and dynamic process risk model of in soft cheese made from pasteurized milk with many uncertain inputs, multivariate sensitivity analysis and MFM are combined to (i) identify the critical control points (CCPs) for throughout the food chain and (ii) compute the critical limits of the most influential process parameters, located at the CCPs, with regard to the specific process implemented in the model. Due to certain forms of interaction among parameters, the results show some new possibilities for the management of microbiological hazards when a FSO is specified.     

UNCERTAIN DEMAND,CONSUMER LOSS AVERSION,AND FLAT‐RATE TARIFFS

We consider a model of firm pricing and consumer choice, where consumers are loss averse and uncertain about their future demand. Possibly, consumers in our model prefer a flat rate to a measured tariff, even though this choice does not minimize their expected billing amount—a behavior in line with ample empirical evidence. We solve for the profit‐maximizing two‐part tariff, which is a flat rate if (a) marginal costs are not too high, (b) loss aversion is intense, and (c) there are strong variations in demand. Moreover, we analyze the optimal nonlinear tariff. This tariff has a large flat part when a flat rate is optimal among the class of two‐part tariffs.     

OUTSOURCING WHEN INVESTMENTS ARE SPECIFIC AND INTERRELATED

Using the universe of large Canadian manufacturing firms in 1988 and 1996, we investigate to what extent outsourcing patterns concord with the predictions of a simple property rights model. The unique availability of disaggregate information on outputs as well as inputs permits the construction of a detailed measure of vertical integration. We rely on five measures of technological intensity to proxy for investments that are likely to be specific to a buyer–seller relationship. A theoretical model that allows for varying degrees of investment specificity and interrelatedness—externalities between buyer and supplier investments—guides the analysis. Property rights predictions on the link between investment intensities and optimal ownership are strongly supported, but only for transactions with low interrelatedness. High specificity and low risk of appropriation strengthen the predictions in the model and in the data.
