一般工科院校研究生兼职辅导员助管工作的实践探索——以南昌航空大学为例

在高校学生工作中，实行研究生兼职辅导员的高校越来越多，研究生兼职辅导员的实施也显得非常必要。通过建立健全研究生兼职辅导员各项管理及考核评价机制，明确研究生兼职辅导员的角色定位，发挥研究生主体意识，形成与研究生人才培养相结合，与研究生职业规划相结合模式，实现研究生思想政治教育工作的创新。

美国和日本高校社会服务模式比较研究

作为高校社会服务的两种基本模式,美国的“高校主导型”模式和日本的“政府主导型”模式均具有政策性、双向性、针对性、实体性、长期性的特征.但由于社会文化不同,二者在社会服务主导方、社会服务内容和社会服务形式方面存在显著差异:美国模式以高校为主导,政府对高校社会服务提供政策和经费的大力支持,但不会对其具体服务方式等加以干预,高校则通过咨询、信息和科研等形式服务于政府,并与企业、社区平等互动,各取所需；而在日本模式中,处于绝对主导地位的政府会通过立法和经济援助等方式对高校的社会服务方式进行细致的指导,引导企业和大学开展以委托形式为主的合作.

OPTIMAL ORDERING IN A DUAL‐SUPPLIER SYSTEM WITH DEMAND FORECAST UPDATES

We study how an updated demand forecast affects a manufacturer's choice in ordering raw materials. With demand forecast updates, we develop a model where raw materials are ordered from two suppliers—one fast but expensive and the other cheap but slow—and further provide an explicit solution to the resulting dynamic optimization problem. Under some mild conditions, we demonstrate that the cost function is convex and twice‐differentiable with respect to order quantity. With this model, we are able to evaluate the benefit of demand information updating which leads to the identification of directions for further improvement. We further demonstrate that the model applies to multiple‐period problems provided that some demand regularity conditions are satisfied. Data collected from a manufacturer support the structure and conclusion of the model. Although the model is described in the context of in‐bound logistics, it can be applied to production and out‐bound logistics decisions as well.     

Regression analysis of informative current status data with the semiparametric linear transformation model

Many methods have been developed in the literature for regression analysis of current status data with noninformative censoring and also some approaches have been proposed for semiparametric regression analysis of current status data with informative censoring. However, the existing approaches for the latter situation are mainly on specific models such as the proportional hazards model and the additive hazard model. Corresponding to this, in this paper, we consider a general class of semiparametric linear transformation models and develop a sieve maximum likelihood estimation approach for the inference. In the method, the copula model is employed to describe the informative censoring or relationship between the failure time of interest and the censoring time, and Bernstein polynomials are used to approximate the nonparametric functions involved. The asymptotic consistency and normality of the proposed estimators are established, and an extensive simulation study is conducted and indicates that the proposed approach works well for practical situations. In addition, an illustrative example is provided.     

The Touchard distribution

We present a novel model, which is a two-parameter extension of the Poisson distribution. Its normalizing constant is related to the Touchard polynomials, hence the name of this model. It is a flexible distribution that can account for both under- or overdispersion and concentration of zeros that are frequently found in non-Poisson count data. In contrast to some other generalizations, the Hessian matrix for maximum likelihood estimation of the Touchard parameters has a simple form. We exemplify with three data sets, showing that our suggested model is a competitive candidate for fitting non-Poisson counts.
