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.

Divorce,living arrangements,and material well-being during the transition to adulthood in rural Malawi

In this paper, we use longitudinal data to investigate how parental death and divorce influence young women’s own experience of divorce in Malawi, a setting where women marry relatively early and unions are fragile. We find that maternal death and parental divorce are positively associated with divorce for young women but, after controlling for socio-demographic and marital characteristics, only the association with maternal death remains statistically significant. Maternal and paternal death are both strongly associated with women’s post-divorce living arrangements, which in turn affects their material well-being. This finding suggests that divorcing at a young age shapes the subsequent life chances of women; although some women return to their parental home and may have the opportunity to reset the transition to adulthood, other women begin their 20s as head of their own household and with considerable material disadvantage.     

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。

显性教育与隐性教育并举增强“基础”课教学实效性

提高"思想道德修养与法律基础"课教学实效性是全社会、高校和"基础"课教师共同关心的重要问题。将显性教育与隐性教育并举,是一条行之有效的途径。显性教育要确立"以学生为本"的理念,拓展教学内容给予学生足够的现实关怀,丰富教学方式以提升学生的精神境界,改进考核方式以培养学生的自我教育能力。开展隐性教育要注重发挥教师自身的人格力量,以个性影响个性;虚功实做,在细节上关爱学生;充分利用现代新媒体,以正能量陶铸学生。     

莎士比亚作品中所体现的同性取向倾向探究——以《威尼斯商人》与十四行诗为例

莎士比亚作为文艺复兴时期杰出的戏剧家和诗人,在欧洲文学史上占有重要的地位,由于莎士比亚的文学地位,使得学术界多以一种崇拜的眼光去解读其作品,而其作品中一些细微之处流露的情绪却很少被人们发觉。男同性恋文学的书写在莎士比亚的作品中对这一命题的表现的十分隐晦,通常欲言又止,但我们还是可以在其作品中发现一些蛛丝马迹。本文旨在通过分析其作品《威尼斯商人》与《莎士比亚十四行诗》来对其作品中所体现的同性化创作倾向与其同性取向倾向进行一些探究。     

制约县域经济发展的因素分析与对策建议

以县级行政区划为单位的县域经济是我国国民经济的基础,是建设小康社会的主战场。我国目前县域经济发展缓慢,已成为宏观经济可持续发展的瓶颈。虽然制约县域经济发展的障碍因素较多,本文仅从经济体制、行政体制、财政体制、金融体制、相关政策制度等方面进行分析,提出改革和完善体制、推行"一主三化"发展战略和制订各县域特色经济总体规划的对策建议。     

论假冒伪劣商品产生和泛滥的社会根源

假冒伪劣商品为什么屡禁不止,且有日益猖獗的趋势呢?本文认为:利益驱动与道德的沦丧是假冒伪劣商品产生的根本原因。在制假售假的过程中,形成了三个利益群体,即制假者、售假者和买假者（特指知假买假者）,他们的行为形成的合力导致了假冒伪劣商品的泛滥。商品二因素的矛盾是假冒伪劣商品产生的社会经济原因。商品生产者与消费者的分离,商品的使用价值与价值的分离,是假冒伪劣商品产生的社会经济基础。治理不力助长了假冒伪劣商品的产生和泛滥。     

我国科技人力资源配置效率评价研究

从投入和产出的角度,构建了我国科技人力资源配置效率评价指标体系;运用数据包络分析（DEA）研究方法,对我国30个地区的2011年科技人力资源配置效率进行了测评,从横向进行了对比分析.结果显示：只有6个地区配置有效,仅占全国总量的20％左右,整体配置效率不甚理想.同时通过松弛变量分析,对DEA无效地区给出了指标调整方向和具体的调整量.
