幼儿家庭教育的合力策略

幼儿期是人一生发展打好基础的一个重要阶段,家庭是幼儿生活和教育的第一场所,家庭教育对幼儿身心发展的影响最深刻、持续时间最长。在幼儿家庭教育中发挥家长榜样力量、尊重幼儿独立地位、发挥学校指导和引领作用、统筹社会资源支持,从而形成以家庭为核心,整合家长、学校、社会的力量,促进教育合力的形成。     

基于自组织的大型建筑企业控制力协同进化研究

针对大型建筑企业控制力动态协同的定量化仿真问题,基于复杂系统视角,应用自组织理论分析大型建筑企业控制力自组织耦合网络作用关系,选择有效朗之万方程构建大型建筑企业控制力系统的自组织协同进化模型,通过线性近似法的性态稳定求解非线性方程的稳定性,得出大型建筑企业控制力系统协同进化演化过程的四个决定性参数,并通过MATLAB软件进行参数枚举取值,具体分析企业控制力协同演化。案例验证该模型可对大型建筑企业控制力协同演化最佳状态实现更加精确的参数取值,并发现大型建筑企业控制力协同演化最佳状态的充要条件,以及一种新的大型建筑企业控制力协同演化状态。     

模具钢干铣削试验及参数优化研究

为了对铣削力做进一步的研究,以及预测铣削参数的改变对铣削力变化的影响,文章建立了铣削力预测模型,引 入了PSO优化算法。试验采用正交设计方法,干式铣削SKD61模具钢;KISTLER测力仪测量铣削力;HRsoft_DW数采软 件采集试验数据,并对数据进行极差分析。研究结果表明每齿进给量是铣削参数中影响铣削力最为主要的因素。研究 验证了PSO算法对铣削参数优化问题具有有效性。     

控制性赋权:基层政府精准扶贫的实践逻辑——基于国家级贫困县J村的田野考察

“赋权”是理解精准扶贫政策的重要视角。田野考察发现基层扶贫实践既有“赋权”又有变通的“控制”,由此导致了扶贫过程中“精准”程度有所差异,为此,需要从基层政府的行动逻辑分析精准扶贫的实践逻辑。研究发现,地方政府从外部选派驻村扶贫工作队,由于较少受到当地社会网络的约束使其能够“理性行动”,但在“限期”脱贫的目标责任制下,基层的扶贫工作队受到了“规避责任”与“追求政绩”的双重约束,故此工作队根据自利原则策略性地选择了赋权或控制策略。进一步考察发现,扶贫工作队主要通过利用传统权力结构、地方性知识及现代化知识话语“异化”赋权策略,从而构建了“控制性赋权”的实践逻辑。基于此,地方政府应着力于构建“外派”与“内生”相结合的基层扶贫工作队,设置部分基于“赋权”“参与”的考核指标,培训提高扶贫干部对贫困户的尊重和理解,从而使得长效脱贫的精准扶贫政策能够得以执行。     

基于索洛模型的区域经济增长驱动因素实证研究

在供给侧改革背景下,区域经济增长的驱动因素显著影响着区域经济的高质量和可持续发展。以索洛增长模型为基本框架,利用2003～2017年安徽省经济发展相关数据开展实证研究,测算资金投入、劳动力投入、技术进步各因素对经济增长的贡献率;同时对模型进行扩展,研究安徽省经济增长的长期驱动力量,对现期和远期的动能转换加以阐述。研究认为,现阶段资金投入仍然是安徽省经济产出的主要驱动因素,劳动力投入的经济推动效应相对较小,技术进步的驱动力量逐步提升,安徽省远期经济发展将主要依赖于技术创新驱动。安徽省应注重科技创新,进行产业结构优化调整,将技术因素融于资金、劳动供给侧,全面深化以技术为主的供给侧改革,加快经济增长动力转型。     

神似译作——倾“力”打造

根据格式塔学派关于"结构同形"的观点,本文认为,引入"力"的概念能为"以形传神"的讨论铺平道路,即文学翻译要做到"神似",就必须充分考量原文的"神"力,"意"力和"形"力,并力争使三者融合.     

"城市化"发展模式的选择与农村剩余劳动力转移

"三农"问题是我国的重中之重,解决"三农"的突破口在农村剩余劳动力的转移,而"城市化"则是转移的最佳途径.我国建国以来一直采用城乡分隔的管理体制,城市化远远滞后于工业化.在城市化不同的发展模式选择上,有以大中城市发展为重心和以发展小城镇为重心两种主要观点.不同的城市化发展模式对农村剩余劳动力转移影响不同.根据我国的国情,我国的城市化模式应该是既能发挥城市的集聚功能,又能很好地实现农村剩余劳动力的转移.由此,我国应该以发展大中城市为主,小城镇建设为辅助.在大城市转移剩余劳动力有限的情况下,小城镇可以发展以为农服务的产业来实现农村剩余劳动力的非农化转移.     

Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ ² and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being. Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically. In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement. Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

Labor force participation and juvenile delinquency in Taiwan: a time series analysis

This study examines the null hypothesis of Granger no-causality between labor force participation (LFP) and juvenile delinquency in Taiwan. In order to explore this issue more thoroughly, this study adopts the approach proposed by Toda and Yamamoto (1995, Journal of Econometrics, 66(1–2), 225–250). It uses official time-series data provided by the Government of Taiwan. After estimating both a four- and five-variable VAR system, one that substitutes both male and female LFP rates for the aggregate LFP rate, the primary findings of this study reveal the following: The higher the past juvenile crime rate, the lower the future aggregate and female LFP rate will be. In addition, the higher the past male LFP rate, the higher the future juvenile crime rate will be. These findings are quite robust in terms of different lag-length structures.

A New Kuznetsian Dynamic: The Knowledge Economy and Income Inequality in the United States, 1917–2008

The rise of the knowledge economy resulted in higher levels of income inequality in the United States and forced many to question the Kuznets Inverted‐U hypothesis. However, this study argues that the establishment of a knowledge economy does not negate the importance of employment shifts for income inequality. Instead, the expansion of knowledge employment alters the major sectors that are responsible for the overall distribution of income. To this end, this article presents the key argument that the current service–knowledge transition impacts income inequality trends, of today, in a way that is similar to the agricultural–industrial transition, of the past. According to the autoregressive conditional heteroskedasticity regressions, the agricultural–industrial transition returns stronger associations with income inequality in the United States before 1950. The agricultural–industrial transition's impact diminishes thereafter as the service–knowledge transition shares a more robust association with income inequality after 1980.
