S变换时变滤波在去噪处理中的应用研究

针对常用的滤波去噪方法都受到使用条件的限制，实际资料的滤波去噪不能达到良好效果，S变换时变滤波克服了传统滤波去噪方法滤波因子不能随时间、频率变化而变化的缺陷。将地震资料用S变换方法变换到时频域，对不同时间内不同频率的噪声部分充零，再将去噪后的地震数据利用S反变换到时间域，以获得所需要的有效信号。通过理论计算分析和实例计算表明，S变换时变滤波能够有效去除不同时段、不同频率的噪声。该方法具有一定的可行性。

Information and Risk Perception: A Dynamic Adjustment Process

It is common in catastrophic food-contamination events that consumers fail to adjust instantaneously to a normal consumption level. One explanation is that consumers only gradually accept new positive information as being trustworthy. The gradual establishment of the trustworthiness of the released information depends on both positive and negative media coverage over time. We examine the individual "trust" effects by extending the prospective reference theory (Viscusi, 1989) to include a dynamic adjustment process of risk perception. Conditions that allow aggregation of changes in risk perceptions across individuals are described. The proposed model describes a general updating process of risk perceptions to media coverage and can be applied to explain the temporal impact of media coverage on consumption of a broad range of goods (food or nonfood). A case study of milk contamination is conducted to demonstrate consumer demand adjustment process to a temporarily unfavorable shock. The results suggest that effects of positive and negative information to adjustment of consumption and risk perception are asymmetric over time.

Risk-Based Design of Aseptic Processing of Heterogeneous Food Products

A risk assessment was performed to incorporate uncertainty in food processing conditions to develop a risk-based sterilization process design. The focus of this analysis was uncertainty associated with heterogeneous food products. Quartered button mushrooms were the chosen food product because it represents the most typical type. A model for sterilization of spherical particles was utilized, and each parameter's uncertainty was characterized for use under Monte Carlo simulation. Various particle distributions and fluid types were compared. The output of the model was the required sterilization time to achieve the target sterilization conditions with 95% probability. This value was then used to determine the mean fluid velocity for a given tube length. Finally, the output from the model was analyzed to determine the confidence in output based on uncertainty in the input parameters. The model was more sensitive to variation in particle size distribution than fluid type for power-law fluids. The 90% confidence interval included a holding time range of 1 min. With a 95% confidence level that only 8% of the data will be below the target sterilization conditions, a maximum of 9% of the data were expected to achieve double the target level. The results of such an analysis would be useful for management decisions concerning the design of aseptic food processing operations.

“入世”以后高新技术产业发展趋势与应对

加入ＷＴＯ，对江苏·南京各个产业来说，都将是利弊互现，正面影响与负面影响同时并存，只不过在程度上有所不同。对高新技术及其产业，则是在挑战与机遇的天平上，更多地向挑战方向倾斜。可是经济全球化是一个不可逆转的历史过程，加入ＷＴＯ，从融入世界全球化潮流中寻找新的发展机遇，也是必须迈出的一步。这里的关键是如何应对。入世以后，我们一定要充分享受人世应有的权利，也承担应该承担的义务，善于应对可能遇到的挑战和冲击。应对得当，我们就可以趋利避害，在新的条件下取得新的发展。 在入世之际，南京市发展高新技术产业要抓…     

The politics and economics of food and famine in Bangladesh in the early 1970s – with special reference to Amartya Sen's interpretation of the 1974 famine

Bangladesh confronted two formidable food crises in 1972 and 1974. While the government succeeded in averting a widely predicted famine in the first case, it failed to prevent an actual famine in the later case when such a cataclysmic disaster was least anticipated. Evidence suggests that the 1974 famine was caused by successive onslaughts of natural disasters such as floods and droughts, and man-made disasters such as the government's inability to import foods, the directing of subsidised food to the politically vocal urban population, an abrupt fall in food aid and political and administrative corruption that encouraged massive hoarding and the smuggling of food grain. This article argues that Noble Laureate economist Amartya Sen's seminal analysis of the 1974 Bangladesh famine on the basis of his 'entitlement approach' fails to capture most of these circumventing factors. The article also argues that by undermining the politico-administrative dynamics of the famine, and by applying his entitlement approach only half-heartedly in examining it, Sen somewhat trivialises the sufferings of a famine-affected population under a corrupt and inefficient political regime.
