新生代农民工融入城市社会的调查与思考——以江西省广丰县农民工为样本

新生代农民工正逐步成为中国生产力大军的主要力量。对江西省广丰县返乡农民工的调查显示,与老一代相比,新生代农民工融入城市社会的主观意愿更加强烈,生产、生活方式更具城市化。他们积极调整自己的生活生产方式、价值观念和行为模式,主动适应并努力融入城市生活,但仍面临城乡分割的二元社会和户籍制度、城市居民的歧视和不健全的社会保障体系等很难跨越的障碍,导致农民工与当地居民同工不同酬,同工不同权,同工不同福利保障。社会要给予新生代农民工更多的人文关怀,政府要发挥好主导作用,增强农民工对城市生活的信心,提高农民工对城市社会的归属感,促进农民工更好地融入城市社会生活。     

第三代新儒家视域下的全球文明对话

文明对话不仅是世界各大文明自身存在与发展的重要前提,也是不同文明之间相互理解、相互融合的必然趋势和必要方式。以杜维明、成中英、刘述先、蔡仁厚为例,第三代新儒家的学者们看到了全球化背景下进行宗教与文明对话的必要性,他们关注儒学与非儒学的交流,注重儒学与世界各大文明的对话,并在理论与行动上积极参与全球文明对话的进行,体现出融摄西学、多向建树的趋势、对儒学地位确认的转变以及对话意识的加强三个重要特征。     

新生代乡村教师的离职意向与政策改进

新生代乡村教师是乡村教育的新生力量和未来的中流砥柱，他们能否安心留在乡村学校从教，关系着乡村教育的可持续发展。为解决乡村教师"留不住"的问题，国务院办公厅于2015年6月发布《乡村教师支持计划（2015-2020年）》，从经济待遇、社会地位、专业发展等方面着手，提出了具体措施。但是通过实证研究发现：当前新生代乡村教师的离职意向仍然普遍存在，尤其是其中的男教师和工作在乡村小学的教师；新时代乡村教师的离职意向，受经济待遇、社会地位、专业发展、个人偏好、乡村文化适应性、家庭和学校支持度、教师教育满意度等多方面因素的影响，其中个人偏好和乡村文化适应性是最主要的影响因素。因此，为了更好地留住新生代乡村教师，仍需在"乡村教师支持计划"现有政策支持的基础上，进一步补充和完善相关的政策措施：（1）重视乡村教师招聘和管理过程中对个人偏好的考察与培育；（2）积极帮助新生代乡村教师适应乡村文化；（3）关心新生代乡村教师的家庭问题，提供帮助和支持；（4）重视乡村学校建设，给予新生代乡村教师更多的组织关怀；（5）出台针对乡村教师的教师教育标准。     

The Sandwich Generation: Dependency, Proximity, and Task Assistance Needs of Parents

This study was designed to determine the extent of sandwiched families and the impact of dependency and proximity to task assistance provided to parent(s). Data were collected in Idaho, Oregon, Utah, and Michigan from a random sample of 40–65-year-old respondents. Fifteen percent are sandwiched between needs of aging parents and financially dependent children. Respondents are much more likely to be providing assistance to mothers than fathers. Parents are most likely to live near, but not necessarily with, the respondent. Spouses and partners' parents, however, are likely to live farther away. Task assistance provided most often to aging parent(s) includes help with transportation and shopping; financial assistance was reported least often. Income of respondent and dependency and proximity of parents are significantly related to providing assistance to parents. This study offers a unique glimpse at the relationships between personal characteristics, dependency, proximity, and task assistance issues as they pertain to the sandwich generation.     

两极交汇的张力——论中国第六代电影的叙事风格

中国第六代电影在叙事风格上呈现为诗意而又残酷、纪实而又魔幻、客观而又热情的两极交汇,这种撕裂感和矛盾性根源于第六代电影人自身文化定位的两难,也反映了当下中国文化深层次的紧张和选择的艰难。     

HR systems and leadership attachment affecting idea generation and implementation: An experiment and two-source multi-level study

This paper focuses on the direct and interactive influence of leadership attachment styles (secure, anxious, and avoidant) and commitment HR system on two distinct stages of the individual innovation process—idea generation and implementation. We test our hypotheses in two studies. An experimental study of undergraduate students establishes a positive effect of secure attachment on idea implementation. The interplay between commitment HR system and avoidant attachment marginally predict idea generation; commitment HR system and neither secure nor anxious attachment predict implementation. A multisource multi-level field study in three EU-based private firms replicates the direct role of commitment HR system in stimulating idea implementation (but not generation) and suggests that secure attachment fosters both generation and implementation, whereas anxious attachment hinders both. Moderation analyses support only a marginal interaction between commitment HR system and secure attachment in fostering idea generation. We discuss theoretical, practical, and future research implications.     

基于多阶段随机规划模型的国债动态积极投资策略

本文提出国债组合投资的多阶段随机规划模型,导出基于未来利率市场不确定信息的具备动态调整特点的国债组合主动投资策略。该模型采用基于利率水平、斜率和曲率"三位一体"的离散情景树刻画未来利率期限结构动态演化过程,其中特别考虑了广义货币供给变动的影响;通过最小化国债组合收益的条件风险价值,对国债组合进行主动动态调整;同时兼顾国债投资安全性、流动性和收益性等要求,实现了国债组合投资管理中利率风险规避和收益能力的有效匹配。实证研究表明,与传统久期配比免疫模型相比,该模型确定的最优策略不仅能够为国债组合提供更强的抵御利率风险能力,而且能够稳步提升其收益空间,为金融机构实现国债投资的主动管理提供决策支持。     

多项目人力资源调度实证研究

针对某公寓大修项目,建立有关人力资源约束下的多项目进度管理问题混合整数规划模型。其中考虑了多种约束,如项目对人员能力、水平的不同要求,而人员又具有多种能力及水平;目标为满足约束的条件下总成本最小化,其中包含按时间计费的工资,和福利等的固定费用。为了简化计算,采用列生成法把复杂的多项目模型分解为一个主问题和多个子问题并协调主问题和子问题求解。同时由于子问题的复杂性难以精确求解,采用启发式算法求解:首先由基于优先原则的启发式方法给出问题的初始解,再由遗传算法寻优。最后通过该实际案例的应用,表明此方法能够快速有效的解决实际问题,给决策者提供信息,帮助指导实践。     

Integrating commercial and residential pickup and delivery networks: A case study

This paper presents a strategic analysis of the network design problem faced by pickup and delivery companies operating in metropolitan areas and serving two or more classes of customers. The focus is on a division that treats commercial and residential customers separately, a situation motivated by their respective geographic densities and the size and frequency of their demand. In constructing driver work areas, it is necessary to take into account expected demand, vehicle capacity, time on the road, and the aspect ratio of the individual territories. This leads to a capacitated clustering problem with side constraints that has been the subject of intense research over the last decade.     

曲线箱梁桥实用设计方法的研究

曲线箱梁桥目前还缺乏比较实用的设计方法．本文对曲线箱梁桥的现有设计方法作了研究，并推荐一种实用设计方法：采用空间梁单元，每个节点取六个自由度；等效梁格的模拟考虑了横向梁格附近有无横隔梁的情况．结果证明，这是一种简便、较精确的设计方法．
