中国本土对话诗学的构建

对话理论、对话诗学的基础是对话哲学,或哲学的对话论转向。在西方,哲学的对话论转向在某种意义上则是以康德的批判哲学为开端的,至海德格尔、伽达默尔的存在论阐释学,特别是巴赫金的对话主义则走向了巅峰。但对话理论在实际的学术世界又是以多维化的面相存在的,如解释学、接受学、阅读学、主体间性、生态论、阴阳交感思想等等,当然还有专门的对话学理论。因此需要从理论上进行新的整合、建构。另外,若从一种平等的关系结构或交流模式来看,中国哲学、诗学中也早就存在相关的对话论了,因此,也有必要建构一种跨文化的、贯通中西的对话理论。至于把这种新的对话理论模式转换成一种对话诗学,就更是一种具有开创性的工作,它是对巴赫金对话诗学的自觉的兼融和超越。     

Note on inventory models with Weibull distribution deterioration

This article explores the inventory model with a general demand rate function in which both the Weibull distributed deterioration and partial backlogging are considered. The inventory model discussed here is based on the important finding by Wu [Wu, K.S., 2001. An EOQ inventory model for items with Weibull distribution deterioration, ramp type demand rate and partial backlogging. Production Planning and Control, 12, 787–793]. There are four parts in our research. First, we derive the analytical framework of the inventory model for a general demand rate function1 1.?Based on detailed suggestions of Professor Wafik H. Iskander, Email: whiskander@mail.wvu.edu . Second, for the ramp type demand, we improve Wu's model to find the criterion to guarantee the existence and uniqueness of the optimal solution. Third, we develop a new model to compensate for the missing case in Wu's article. Fourth, we combine our results to show that our findings are applicable to the ramp type demand inventory model, so that the optimal solution is independent of the demand function. Finally, some numerical examples and graphs are provided to illustrate our discovery and demonstrate the application of our analytical framework.     

Health Risk Characterization of Chlorpyrifos Using Epidemiological Dose‐Response Data and Probabilistic Techniques: A Case Study with Rice Farmers in Vietnam

Various methods for risk characterization have been developed using probabilistic approaches. Data on Vietnamese farmers are available for the comparison of outcomes for risk characterization using different probabilistic methods. This article addresses the health risk characterization of chlorpyrifos using epidemiological dose‐response data and probabilistic techniques obtained from a case study with rice farmers in Vietnam. Urine samples were collected from farmers and analyzed for trichloropyridinol (TCP), which was converted into absorbed daily dose of chlorpyrifos. Adverse health response doses due to chlorpyrifos exposure were collected from epidemiological studies to develop dose‐adverse health response relationships. The health risk of chlorpyrifos was quantified using hazard quotient (HQ), Monte Carlo simulation (MCS), and overall risk probability (ORP) methods. With baseline (prior to pesticide spraying) and lifetime exposure levels (over a lifetime of pesticide spraying events), the HQ ranged from 0.06 to 7.1. The MCS method indicated less than 0.05% of the population would be affected while the ORP method indicated that less than 1.5% of the population would be adversely affected. With postapplication exposure levels, the HQ ranged from 1 to 32.5. The risk calculated by the MCS method was that 29% of the population would be affected, and the risk calculated by ORP method was 33%. The MCS and ORP methods have advantages in risk characterization due to use of the full distribution of data exposure as well as dose response, whereas HQ methods only used the exposure data distribution. These evaluations indicated that single‐event spraying is likely to have adverse effects on Vietnamese rice farmers.

我国城乡老年人口生活质量比较研究

老年人口的核心问题是生活质量问题,对老年人口主观幸福感的关注有助于提高老年人口的生活质量.基于杭州市城乡老年人口主观幸福感的调查研究发现,城市老年人比农村老年人具有更强烈的主观幸福感.子女孝顺是影响城市和农村老年人主观幸福感的最主要因素;经济状况、对社区工作满意度、婚姻、性别等也是共同影响因素,但影响程度在城市和农村间存在差异.此外,在城市模型中,自我照料程度、子女个数等个人特征因素对老年人主观幸福感影响显著;在农村模型中,经济来源、对权益受侵害后的处理方式等经济和社会保障因素对老年人主观幸福感影响显著.总之,城乡老年人对提高生活质量的需求不同,城市老年人已侧重于对精神的需求,而农村老年人首先还需要物质的满足.

Additive and Multiplicative Models and Multistage Carcinogenesis Theory

In light of the Armitage-Doll multistage carcinogenesis theory, this paper examines the assumption that an additive relative risk relationship is indicative of two carcinogens that affect the same stage in the cancer process. We present formulas to compute excess cancer risks for a variety of patterns for limited exposure durations to two carcinogens that affect the first and penultimate stages; and using an index of synergy proposed by Thomas (1982), we find a number of these patterns to produce additive, or nearly additive, relative risk relationships. The consistent feature of these patterns is that the two exposure periods are of short duration and occur close together.
