“三鹿奶粉事件”中生鲜乳收购站的产品责任分析

将初级农产品作为产品责任法中的"产品",其生产者认定为产品责任承担主体,加大对消费者的保护力度,是世界产品责任立法的发展趋势.我国应将生鲜乳等初级农产品纳入产品责任的"产品"范围之内,让缺陷初级农产品生产者对受损害的消费者直接承担产品责任,以有效遏制和防范产品质量安全事件的频发.在 "三鹿奶粉事件"中,缺陷生鲜乳的生产者--收购站应承担产品责任.在产品责任构成要件方面,应该适当降低消费者对因果关系的证明标准.     

表演和录音录像制品著作权归属辨析

对原有作品的表演及在原有作品基础上形成的录音录像制品包含原作作者和表演者或录音录像制作者的双重创造性劳动。因此，对表演和录音录像制品也会存在类似于演绎作品的双重权利，本文力图分辨表演者或录音录像制作者和原作作者对表演和录音录像制品分别享有哪些权利及其权利性质。     

Development of a Quantitative Microbial Risk Assessment for Human Salmonellosis Through Household Consumption of Fresh Minced Pork Meat in Belgium

A quantitative microbial risk assessment (QMRA) according to the Codex Alimentarius Principles is conducted to evaluate the risk of human salmonellosis through household consumption of fresh minced pork meat in Belgium. The quantitative exposure assessment is carried out by building a modular risk model, called the METZOON-model, which covers the pork production from farm to fork. In the METZOON-model, the food production pathway is split up in six consecutive modules: (1) primary production, (2) transport and lairage, (3) slaughterhouse, (4) postprocessing, (5) distribution and storage, and (6) preparation and consumption. All the modules are developed to resemble as closely as possible the Belgian situation, making use of the available national data. Several statistical refinements and improved modeling techniques are proposed. The model produces highly realistic results. The baseline predicted number of annual salmonellosis cases is 20,513 ( SD 9061.45). The risk is estimated higher for the susceptible population (estimate  4.713 × 10⁻⁵; SD 1.466 × 10⁻⁵  ) compared to the normal population  (estimate 7.704 × 10⁻⁶; SD 5.414 × 10⁻⁶)  and is mainly due to undercooking and to a smaller extent to cross-contamination in the kitchen via cook's hands.

Demand Systems Estimation With Microdata: A Censored Regression Approach

Demand systems estimation increasingly makes use of household-level microdata, mainly to measure the effects of demographic variables. Data based on these household-expenditure surveys present a major estimation problem. For any given household, many of the goods have zero consumption, implying a censored dependent variable. Techniques which do not take this censored dependent variable into account will yield biased results. We utilize a censored regression approach that is computationally simple, consistent, and asymptotically efficient. The results are then presented and compared with those obtained using an uncensored technique.

产品品种繁多类型企业投入产出表的处理思想与方法

对于生产装配性产品的机械企业，由于产品与原材料种类繁多，将造成企业投入产出表的规模庞大，致使投入产出表的编制、计算和使用产生诸多问题，甚至难以实现。为了控制表的规模，常采用将消耗量相近、生产工艺相近的产品合并的做法。但这种做法严重影响了投入产出表的精度和应用效果。因此，本文讨论了更为有效的解决这类问题的思想和方法。     

论文化产品的价值实现与价格形成

文化产品是其价值和使用价值的统一体。当文化产品的交换价值确切地反映价值和使用价值时,文化的开发和利用处于良好状态,反之,便造成文化产品价值的湮没。文化产品价值实现程度的高低取决于文化产品使用者的需求程度,因此,不确定性是文化产品价格的最显著特性。文化产品价格并非由某个因素单独决定,而是由效用、成本、垄断等因素共同作用、综合决定,即成本和效用共同决定文化产品的价格区间,垄断则带来了超出价格区间的特殊价格。     

三峡文化的旅游开发研究

Measurement error, skewness, and risk analysis: coping with the long tail of the distribution.

Probabilistic risk analyses often construct multistage chance trees to estimate the joint probability of compound events. If random measurement error is associated with some or all of the estimates, we show that resulting estimates of joint probability may be highly skewed. Joint probability estimates based on the analysis of multistage chance trees are more likely than not to be below the true probability of adverse events, but will sometimes substantially overestimate them. In contexts such as insurance markets for environmental risks, skewed distributions of risk estimates amplify the "winner's curse" so that the estimated risk premium for low-probability events is likely to be lower than the normative value. Skewness may result even in unbiased estimators of expected value from simple lotteries, if measurement error is associated with both the probability and pay-off terms. Further, skewness may occur even if the error associated with these two estimates is symmetrically distributed. Under certain circumstances, skewed estimates of expected value may result in risk-neutral decisionmakers exhibiting a tendency to choose a certainty equivalent over a lottery of equal expected value, or vice versa. We show that when distributions of estimates of expected value are, positively skewed, under certain circumstances it will be optimal to choose lotteries with nominal values lower than the value of apparently superior certainty equivalents. Extending the previous work of Goodman (1960), we provide an exact formula for the skewness of products.
