社区矫正心理干预队伍建设探索

社区矫正心理干预队伍建设是促进社区矫正工作快速高效发展的重要议题之一。社区矫正心理干预队伍应具有自己独特的素质要求,在构成上应基于现有的社区矫正工作队伍结构,由司法所工作人员、相关社会团体和社会志愿者组成,对三者在心理干预工作中的角色和作用应予以明确。     

民国初期全国性教育团体群落论

民国初期,以全国教育会联合会、中华职业教育社和中华教育改进社等为代表的全国性教育团体纷纷涌现并逐渐群落化。他们顺应时代的要求而产生,以不同定位满足教育界的不同需要;他们集中了教育界的优秀人物、当时著名教育家构成的群体成为社团群落的核心领导力量;他们都在不断的自我调适中找到了发挥作用的着力点,也形成了各自的特色,充分发挥了教育社团群落的社会作用。     

Regularization and variable selection via the elastic net

Summary.  We propose the elastic net, a new regularization and variable selection method. Real world data and a simulation study show that the elastic net often outperforms the lasso, while enjoying a similar sparsity of representation. In addition, the elastic net encourages a grouping effect, where strongly correlated predictors tend to be in or out of the model together. The elastic net is particularly useful when the number of predictors ( p ) is much bigger than the number of observations ( n ). By contrast, the lasso is not a very satisfactory variable selection method in the p ≫ n case. An algorithm called LARS-EN is proposed for computing elastic net regularization paths efficiently, much like algorithm LARS does for the lasso.     

台州方言在吴语中的内外关系

自20世纪80年代起,台州方言在吴语中的分片问题上一直处于游移状态。文章通过台州方言内部各点与南、北部吴语进行最具代表性的语音、词汇、语法的特征项的比较,以及地理位置和历史沿革的分析,表明台州方言与南部吴语的相似度超过了北部吴语。台州方言在吴语中是应该自成一片的。如果非得对吴语进行＂非南即北＂的划分的话,那么,台州方言属于南部吴语为佳。     

Grouping Variable Selection by Weight Fused Elastic Net for Multi-Collinear Data

In this article, we consider the problem of variable selection and estimation with the strongly correlated multi-collinear data by using grouping variable selection techniques. A new grouping variable selection method, called weight-fused elastic net(WFEN), is proposed to deal with the high dimensional collinear data. The proposed model, combined two different grouping effect mechanisms induced by the elastic net and weight-fused LASSO, respectively, can be easily unified in the frame of LASSO and computed efficiently. The performance with the simulation and real data sets shows that our method is competitive with other related methods, especially when the data present high multi-collinearity.

高校学报专业化、集团化发展的设想

高校学报的发展在市场经济条件和现有职称评定制度下已面临多种困境。走专业化、集团化道路是高校学报与世界接轨摆脱困境的唯一途径。组建高校学报集团,可以分两步实施,国家出版行政管理部门须在组建中起到重要协调作用。     

Grouping strategies and thresholding for high dimensional linear models

The estimation problem in a high regression model with structured sparsity is investigated. An algorithm using a two-step block thresholding procedure called GR-LOL is provided. Convergence rates are produced: they depend on simple coherence-type indices of the Gram matrix – easily checkable on the data – as well as sparsity assumptions of the model parameters measured by a combination of l₁ within-blocks with _lq$l_q$, q<1$q<1$ between-blocks norms. The simplicity of the coherence indicator suggests ways to optimize the rates of convergence when the group structure is not naturally given by the problem or is unknown. In such a case, an auto-driven procedure is provided to determine the regressor groups (number and contents). An intensive practical study compares our grouping methods with the standard LOL algorithm. We prove that the grouping rarely deteriorates the results but can improve them very significantly. GR-LOL is also compared with group-Lasso procedures and exhibits a very encouraging behavior. The results are quite impressive, especially when GR-LOL algorithm is combined with a grouping pre-processing.     

平话系属争论中的逻辑问题

对于平话尤其是桂南平话的归属,学术界有不少争议。焦点在于平话是独立一区还是归属粤语。平话的归属之所以引起争论,一个关键便是前提没有确定。在这样的背景下讨论问题,出现分歧就势所难免。而问题的关键就是确立粤语的典型特征这样一个逻辑前提,以此作为基础,问题的探讨才能有科学的依据和较强的说服力。本文认为平话不宜归入典型的粤语,但也不宜独立为一级的方言大区,在现有的条件下,与其将精力花在纠缠平话属不属于粤语,粤语有哪些典型特征这类理论上的“难题”,不如将更多的精力放在调查、了解和抢救各地具有特色但却日趋消磨的汉语方言上。
