Group Variable Selection with Oracle Property by Weight-Fused Adaptive Elastic Net Model for Strongly Correlated Data

This paper is the generalization of weight-fused elastic net (Fu and Xu, 2012 Fu, G., Xu, Q. (2012). Grouping variable selection by weight fused elastic net for multi-collinear data. Communications in Statistics-Simulation and Computation 41(2):205–221.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), which performs group variable selection by combining weight-fused LASSO(wfLasso) and elastic net (Zou and Hastie, 2005 Zou, H., Hastie, T. (2005). Regularization and variable selection via the elastic net. Journal of the Royal Statistical Society: Series B (Statistical Methodology) 67(2):301–320.[Crossref], [Web of Science ®] , [Google Scholar]) penalties. In this study, the elastic net penalty is replaced by adaptive elastic net penalty (AdaEnet) (Zou and Zhang, 2009 Zou, H., Zhang, H. (2009). On the adaptive elastic-net with a diverging number of parameters. Annals of Statistics 37(4):1733–1751.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), and a new group variable selection algorithm with oracle property (Fan and Li, 2001 Fan, J., Li, R. (2001). Variable selection via nonconcave penalized likelihood and its oracle properties. Journal of the American Statistical Association 96(456):1348–1360.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; Zou, 2006 Zou, H. (2006). The adaptive lasso and its oracle properties. Journal of the American Statistical Association 101(476):1418–1429.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) is obtained.     

A probabilistic model for predicting total basal area growth of closed uneven-aged stand

In this note, a probabilistic method for predicting the future total net basal area of closed uneven-aged stand based on “Stand Tally” is proposed and an example is given.     

On-Line Scheduling of Two-Machine Open Shops Where Jobs Arrive Over Time

We investigate the problem of on-line scheduling two-machine open shops with the objective of minimizing the makespan.Jobs arrive independently over time, and the existence of a job is not known until its arrival. In the clairvoyant on-line model, the processing requirement of every job becomes fully known at the arrival of the job, while inthe non-clairvoyant on-line model, this processing requirement is notknown until the job is processed and completed.In both models, scheduling of a job is irrevocable.We study the two-machine open shop problem for both models in the preemptive and in the non-preemptive version. For each of the four variants, we provide an algorithm that is best possible with respect to the worst-case performance. In the clairvoyant on-line model, the best worst-case performance ratios are 5/4 (preemptive) and 3/2 (non-preemptive), and in the non-clairvoyant on-line model, they are 3/2 (preemptive and non-preemptive).

语用模糊的动态初探

文章从动态语用角度就语用模糊在言语交际中的动态性及动态过程进行探讨和例析。意义交流应是语用模糊在交际中的最高层面;动机作为整个动态系统的出发点对语用模糊起选择作用;语境对语用模糊有制约和释义作用;语用模糊使话语含有意义潜势,使之产生特定的交际效果,而受话人的反馈使意义得以协调并推动交际过程作动态变化发展。     

论我国附带民事诉讼制度的改进

我国在附带民事诉讼制度的设计上遵循的是"刑优于民"的立法指导思想,所附带的民事诉讼缺乏应有的独立地位,不能给予被害人应有的程序保障和实体保障.应对我国附带民事诉讼进行扩大诉讼当事人的主体范围、扩大请求赔偿损失的范围、赋予当事人程序选择权、明确附带民事诉讼时效等方面的改进.

我国企业实施战略成本管理的问题与对策

战略成本管理是适应企业战略管理的需要,以及改革传统成本管理缺陷而产生的一种新的成本管理方法.通过实证研究分析,总结出我国企业在实施战略成本管理过程中存在诸如对战略成本管理的内涵理解不到位,价值链分析和SWOT分析不充分,信息有效性不足,战略成本管理方法和人力资源管理落后等问题.针对问题实际,从更新观念提高素质,组建战略成本管理部门,搭建企业信息化平台,实施战略人力资源管理等方面入手,提出了改进企业战略成本管理的措施.     

基于主体功能区规划的区域土地利用情景分析框架——以贵州省毕节市为例

构建一个基于主体功能区规划的区域土地利用情景分析框架,为市、县统筹国家需求与地区实际合理制定土地利用目标与策略提供方法支撑。以欠发达地区贵州省毕节市为例,对该分析框架进行了应用。结果显示:在"优先满足生态安全和经济发展基本需求,协同平衡满足粮食安全需求"土地利用策略下,毕节市未来的土地利用方案应以生态优先为原则,并强调发展模式的转变,从而协同满足经济发展、粮食安全、生态安全的用地需求。与毕节市相似的欠发达地区需要改变因后备资源优势而采取"大投入换快增长"的土地利用观念,防止走"先破坏后治理"的发展老路,应采取基于综合战略目标的生态优先倒逼机制,引导地区发展方式转变,从而保证地区的可持续发展。分析结果验证了土地利用情景分析框架的适用性,可以尝试将其应用于市、县层面土地调控与规划管理实践。
