女性写作与女性身份重塑:简·爱的矛盾性新探

在阅读勃朗特自传体小说《简·爱》时,通过仔细阅读文本本身,我们就会发现一个性格充满矛盾的简·爱。有人说这是小说的失败。但笔者认为,如果从女性写作视阈观看,简·爱性格的多重性、矛盾性和不稳定性,她的自卑性,甚至她道德的"虚伪性",不仅反映了当时英国女性的自身特征,而且还帮助作者和简·爱重新建构了她们的女性身份。

政策执行波动与基层治理问题

在中国,公共政策在执行过程中会出现消极执行的问题,同时也常常出现运动式执行的情况。二者的交替出现使得公共政策表现出波动式执行的特征。对此,本文通过对一个政策执行案例动态过程的深入分析,揭示出这种政策执行的问题与基层政府在执行政策过程中所面临的环境有关。政策适用性低与执行压力变化是导致消极执行与运动式执行的根源。而且,这种波动式的政策执行往往在基层社会积累和引发矛盾,造成治理问题。

绩效与不足:成都会展业现状分析

近年,成都会展业发展迅速,多种会展经济形态得到全面发展,展览场馆数量较足,政府主导大型展会以及多层次的会展人才培养体系对会展业快速发展提供了必要的保障。然而,成都会展业仍然存在着品牌化和国际程度不高、场馆规模小和利用率较低、政府管理理念仍需创新、"产学研"结合不紧密等问题。本文通过分析当下成都会展业的绩效与不足,希望能为优化成都会展经济的产业结构、促进会展产业的转型和品牌升级提供有益的参考。

Approximation strategy-proof mechanisms for obnoxious facility location on a line

In the facility location game on a line, there are some agents who have fixed locations on the line where an obnoxious facility will be placed. The objective is to maximize the social welfare, e.g., the sum of distances from the facility to all agents. On collecting location information, agents may misreport the locations so as to stay far away from the obnoxious facility. In this paper, strategy-proof mechanisms are designed and the approximation ratio is used to measure the performances of the strategy-proof mechanisms. Two objective functions, maximizing the sum of squares of distances (maxSOS) and maximizing the sum of distances (maxSum), have been considered. For maxSOS, a randomized 5/3-approximated strategy-proof mechanism is proposed, and the lower bound of the approximation ratio is proved to be at least 1.042. For maxSum, the lower bound of the approximation ratio of the randomized strategy-proof mechanism is proved to be 1.077. Moreover, a general model is considered that each agent may have multiple locations on the line. For the objective functions maxSum and maxSOS, both deterministic and randomized strategy-proof mechanisms are investigated, and the deterministic mechanisms are shown to be best possible.     

Asymptotically optimal policy for stochastic job shop scheduling problem to minimize makespan

This paper studies the large-scale stochastic job shop scheduling problem with general number of similar jobs, where the processing times of the same step are independently drawn from a known probability distribution, and the objective is to minimize the makespan. For the stochastic problem, we introduce the fluid relaxation of its deterministic counterpart, and define a fluid schedule for the fluid relaxation. By tracking the fluid schedule, a policy is proposed for the stochastic job shop scheduling problem. The expected value of the gap between the solution produced by the policy and the optimal solution is proved to be O(1), which indicates the policy is asymptotically optimal in expectation.
