社会转型期新生代员工工作不安全感问题

作为当前核心人力资源的新生代员工,其在社会剧烈转型过程中产生的工作不安全感问题引发社会各界广泛关注。新生代员工工作不安全感具有明显的时代特征,它的形成既与员工个性特征有关,也受外部经济环境、组织环境以及家庭环境等因素的影响。强烈的工作不安全感会对新生代员工的组织承诺、离职率、组织公民行为甚至创新能力等带来诸多负面影响,组织管理者必须采取适当措施有效管理新生代员工的工作不安全感问题,实现员工与组织的和谐发展。

Convergence rates for uniform confidence intervals based on local polynomial regression estimators

We investigate the convergence rates of uniform bias-corrected confidence intervals for a smooth curve using local polynomial regression for both the interior and boundary region. We discuss the cases when the degree of the polynomial is odd and even. The uniform confidence intervals are based on the volume-of-tube formula modified for biased estimators. We empirically show that the proposed uniform confidence intervals attain, at least approximately, nominal coverage. Finally, we investigate the performance of the volume-of-tube based confidence intervals for independent non-Gaussian errors.

一种疏水缔合聚合物快速溶解方法研究

研究了疏水缔合聚合物（AP–P4）经过拉伸装置后的溶解时间。结果表明，拉伸装置可以缩短疏水缔合聚合物的溶解时间；拉伸装置的最佳间距为200 μm，此时疏水缔合聚合物的溶解时间为25 min。经拉伸装置处理后的疏水缔合聚合物可以在30 min 内达到溶解；提高温度可以显著改善疏水缔合聚合物的溶解效果，缩短疏水缔合聚合物的溶解时间。     

农户与企业组织关系分析

随着市场经济的发展,在产业组织关系中农户和企业之间形成集合依存、序次依存和交互依存等多种依存方式,以及相应的多向协调机制。这种产业组织关系和协调机制,使得农户收入得到明显提高,企业经济效益和社会效益获得提升,消费者购买的农产品质量也有所提高。     

多重假设检验中参数估计问题研究

在多重假设检验中,真正原假设的个数m0是未知的,但是它有着很重要的影响,因此,它在最近的统计文献中备受关注.文章综述了三种主要的估计方法:最低斜率法、三次样条法、均值估计方法.然后将上述三种方法结合起来,提出了新的估计方法:均值三次样条法,并主要研究了其在微阵列数据上的应用.大量的模拟研究表明,和其他方法相比,新的估计方法具有较小的偏差和标准差.最后利用真实数据来对估计方法进行评估,并找出了差异表达性基因.模拟和实际数据表明此方法具有显著性提高.     

Analysis of dependently truncated data in Cox framework

Truncation is a known feature of bone marrow transplant (BMT) registry data, for which the survival time of a leukemia patient is left truncated by the waiting time to transplant. It was recently noted that a longer waiting time was linked to poorer survival. A straightforward solution is a Cox model on the survival time with the waiting time as both truncation variable and covariate. The Cox model should also include other recognized risk factors as covariates. In this article, we focus on estimating the distribution function of waiting time and the probability of selection under the aforementioned Cox model.
