体制化“空转”： 发展悖境中社区工作站运行的组织行为分析——以S市X社区为例

社区工作站作为承接政府社区公共服务职能的新型社会组织，似乎并未真正摒弃行政化积弊及普遍性怠政现象，凸显出事实与价值背离的发展悖境态势。在当前新工作情境下，社区工作站无论是窗口、街头还是社区,其实都呈现出无工作负荷的“空转”状态，并彰显惯习性运作的体制化印记，而体制化“空转”的致因逻辑又在于情境暗示效应下的规章制度软性约束、街道办“示范效应”及社区工作“应付法则”。对此，有必要由情境反思予以解悖，从“干净的石板（clean slate）”出发，在政策原点上破解社区工作站的运行困境，尝试社区工作站的机构撤并及职能删减,以摒除社区公共服务工作中本不该有的体制化“空转”状态，力促基层组织体制改革去行政化的不二取向。

Price-setting newsvendor with strategic consumers

We consider a newsvendor who sells a single product over a single season with the objective of determining both the selling price and stock quantity to maximize the expected profit. The customers are strategic and we consider two demand cases: additive and multiplicative. For each case, we derive the newsvendor׳s optimal decisions and demonstrate that neglecting the price-sensitivity of demand leads the newsvendor to make sub-optimal decisions. Moreover, we show that under certain conditions, strategic consumer behavior may positively affect the newsvendor׳s optimal expected profit in the additive demand case.     

外国新闻史教材存在问题及对策分析

外国新闻史是新闻传播类专业本科阶段的必修课,师生共同关心教材的选用。综观目前正规出版的教材,问题不容忽视,包括翻译不规范、基本史料表述不一、史观带有浓厚的意识形态色彩等。这些问题给学生带来困惑,给教学带来困难。解决的办法首先是要重视规范,遵守约定俗成的规则,其次要改变既有思维,学会客观、理性地对待他国新闻传播史。     

The “Silent Dog” Method: Analyzing the Impact of Self-Generated Rules When Teaching Different Computer Chains to Boys with Autism

The purpose of the study was to extend the literature on verbal self-regulation by using the “silent dog” method to evaluate the role of verbal regulation over nonverbal behavior in 2 individuals with autism. Participants were required to talk-aloud while performing functional computer tasks.Then the effects of distracters with increasing demands on target behavior were evaluated as well as whether self-talk emitted by Participant 1 could be used to alter Participant 2''s performance. Results suggest that participants'' tasks seemed to be under control of self-instructions, and the rules generated from Participants 1''s self-talk were effective in teaching computer skills to Participant 2. The silent dog method was useful in evaluating the possible role of self-generated rules in teaching computer skills to participants with autism.     

An economic model for the quality selection problem

The object of an economic model for the quality selection problem is to select the best parameter value for an input quality characteristic (X) so that the quality loss incurred on an output quality characteristic (Y) is minimized. The relation function between Y and X is assumed to be known throughout the article. In the work of Taguchi's experimentations, the selection of best parameter values is solved by two-step optimization when Y is adjustable. In the article, it is further extended to the case where Y is non-adjustable. An economic quality selection model with a general relation function is proposed based on a Taylor-series method for both adjustable and non-adjustable cases. A special case of a quality selection model with a quadratic relation function is also studied. A circuit example provided by Taguchi is presented to illustrate the use of this model.     

Exact and approximate distributions for linear contrasts of means and variances

A Bayesian analysis is presented for the K-group Behrens-Fisher problem. Both exact posterior distributions and approximations were developed for both a general linear contrast of the K means and the K variances, given either proper diffuse or informative conjugate priors. The contrast of variances is a unique feature of the heterogeneous variance model that enables investigators to test specific effects of experimental manipulations on variance. Finally, important-differences were observed between the heterogeneous variance model and the homogeneous model.     

Sums of powers of binomial coefficients

An asymptotic series for sums of powers of binomial coefficients is derived, the general term being defined and usable with a computer symbolic language. Sums of squares of coefficients in the symmetric case are shown to have a link with classical moment problems, but this property breaks down for cubes and higher powers. Problems of remainders for the asymptotic series are mentioned. Using the reflection formula for I'(.), a continuous form for a binomial function is set up, and this becomes oscillatory outstde the usual range. A new contmued fraction emerges for the logarithm of an adjusted sum of binomial squares. The note is a contribution to the problem of the interpretation of asymptotic series and processes for their convergence acceleration.
