从生产到生活——试论"生活世界"对工匠精神培育的影响及路径再建构

"生活世界"研究对工匠精神培育具有重要影响.作为一种个体共同文化生活背景的互动及实践场域,"生活世界"具有先验性、实践性以及多样性等特征.在日常生活实践中,它可以通过铸就惯习、内省文化和净化理念等方式,使工人呈现出一种"尽心、负责"、"多元化视角"以及"善于坚守"等品质.在现实生活中,"生活世界"也易出现工人工匠精神未顺利实现障碍,原因与现代化术语垄断、工厂被视为一种替代生活方式以及人的理念异化等社会不良现象存在有关.要解决以上问题,形成新的分析视角,必须从建立更丰富实践理论体系、树立更正确社会分析目标和形成更浓厚"地方性知识"氛围等方面入手.由此,工匠精神才能得到更好培育,其分析路径也才能得到更进一步转化.     

融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法研究

挖掘特定产品的需求模式无法从整体掌握该类产品的市场特征；短生命周期体验品因缺乏历史销售数据，并且销售总量波动性极大，尤其需要从整体掌握销售总量与产品属性间关系的需求特征规律，但又难以挖掘，亟待提出适用于该类产品的需求特征模式挖掘方法。基于按销售总量分区后各区的需求特征的规律性，提出了一种按销售总量分区、以已有产品介绍集和销售总量为源信息、适用于新产品开发前使用、融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法。该方法包括基于内容分析法的产品属性挖掘方法和基于关联分析的产品属性关系模式挖掘方法。前者可以得到较全面的产品属性；后者能够构建不同销售总量区间内产品集的属性关系模式，得到各区间的产品属性关系网，获得高销售总量区间具备，但中、低区间不具备的属性关系模式，从而获得需求特征模式。通过不断更新产品介绍集和销售总量并迭代挖掘，该方法能够动态挖掘需求特征模式。最后利用2013至2016年国产犯罪和爱情类电影数据验证了该方法的可行性，并得到了这两类电影的产品属性及近年的需求特征模式，可用于指导这两类电影的创作。     

Exploring the relation between maternal mind‐mindedness and children’s symbolic play: A longitudinal study from 6 to 18 months

Relations between mothers’ mind‐mindedness (appropriate attunement to their infants’ internal states) at 6 and 12 months and infants’ early symbolic play during infant–mother pretense at 12 and 18 months were investigated in a sample of 43 mothers and infants. Mothers’ appropriate mind‐related comments were associated with average level, length, complexity, and maturity level of symbolic play. Specific sub‐categories of appropriate mind‐related comments were identified as independent predictors of children's symbolic play. Appropriate comments about desires and cognitions at 6 months were associated with average level and length of episodes, as well as with maturity level of symbolic play at 12 months. Longitudinal stability in the appropriateness and content of mothers’ mind‐related comments was also investigated. The results are discussed in terms of the proposal that attunement to specific types of internal state should vary as a function of infant age in order to index mind‐mindedness.     

新冠肺炎疫情下对完善快递末端配送体系建设的思考——以重庆市为例

自新冠肺炎疫情发生以来，快递业为应急救援物资和人民群众日常基本生活物资运输和寄递服务、畅通经济循环、满足民生需要等方面做出了重要贡献，为疫情防控提供了强有力的支撑；但同时也暴露出了一些问题，集中体现在末端配送体系不健全、末端收投不畅等方面。在对电子商务和快递业发展现状进行分析的基础上，对快递末端配送的主要模式和发展趋势进行了论述，结合重庆市的实际情况，分析了其末端配送存在的不足，并从公共服务平台搭建、智能化无接触式配送构建、乡村快递服务网络完善、快递员队伍建设等方面提出了对策建议，以助推重庆经济社会高质量发展。     

A New Methodology for Before–After Safety Assessment Using Survival Analysis and Longitudinal Data

The widely used empirical Bayes (EB) and full Bayes (FB) methods for before–after safety assessment are sometimes limited because of the extensive data needs from additional reference sites. To address this issue, this study proposes a novel before–after safety evaluation methodology based on survival analysis and longitudinal data as an alternative to the EB/FB method. A Bayesian survival analysis (SARE) model with a random effect term to address the unobserved heterogeneity across sites is developed. The proposed survival analysis method is validated through a simulation study before its application. Subsequently, the SARE model is developed in a case study to evaluate the safety effectiveness of a recent red‐light‐running photo enforcement program in New Jersey. As demonstrated in the simulation and the case study, the survival analysis can provide valid estimates using only data from treated sites, and thus its results will not be affected by the selection of defective or insufficient reference sites. In addition, the proposed approach can take into account the censored data generated due to the transition from the before period to the after period, which has not been previously explored in the literature. Using individual crashes as units of analysis, survival analysis can incorporate longitudinal covariates such as the traffic volume and weather variation, and thus can explicitly account for the potential temporal heterogeneity.     

俄国1866年国家农民改革法令论析

国家农民是1861年俄国农奴制改革中三类主要农民之一,与皇室农民和地主农民的主要区别是拥有人身权.1866年国家农民改革是1861年农民改革的延续和扩展,是将1861年2月19日法令推行到国家农村的具体实践.国家农民改革法令的出台并不顺利,是各派考量地主农民改革经验和国家农民现实后做出的稳妥选择.改革法令推行使国家农民土地保障程度降低而赋役负担依旧,改革前拥有人身权的相对优势没能扭转改革后与地主农民同样的命运.从国家农民改革的目标、改革法令的拟定、法令规定与法令落实等维度来看,这一结果在所难免.     

远海岛礁冷链物流体系优化模型及其集成算法

为研究远海岛礁渔获冷链物流的运行方案，本文选择了岛礁冷库储存中转和海上直接收购等两种不同的渔获运输方式，同时考虑了中转冷库选址、中转运输和直接收购船舶配备、航线配置、在渔场停留时间和渔获运输损耗等诸多复杂问题，构建了远海冷链物流体系组合优化模型。求解时，提出了一种以遗传算法（GA）为外部框架，以改进的模拟植物生长算法（PGSA）为内部模块，通过信息传递实现内外连接交互的集成算法。最后，以我国南海远海岛礁及渔场为实例进行分析，取得了较好效果。通过与传统遗传算法对比，本文优化结果、稳定性及计算速度等均有明显提高，从而证明了本文所建模型与算法的合理性和有效性。
