Validation of the Learning Transfer System Inventory (LTSI) in the Korean corporate context

Lack of a valid instrument to measure learning transfer predictors has been the major obstacle hindering Human Resource Development (HRD) professionals from moving forward. This problem is one of the lingering HRD issues in South Korea, in which human resources have been strategically emphasized as a critical asset due to the scarcity of natural resources. To address this issue, this study aims at testing the validity and reliability of the data collected with the Korean Learning Transfer System Inventory (LTSI) Version 4. A sample of 753 managers from 16 Korean industries was divided into two subsamples for exploratory and confirmatory factor analyses. Reliability and the effect of common method variance on the factor structure were examined, with the results suggesting that the LTSI is valid for use in the Korean industry.     

A lower bound for the adaptive two-echelon capacitated vehicle routing problem

Adaptive two-echelon capacitated vehicle routing problem (A2E-CVRP) proposed in this paper is a variant of the classical 2E-CVRP. Comparing to 2E-CVRP, A2E-CVRP has multiple depots and allows the vehicles to serve customers directly from the depots. Hence, it has more efficient solution and adapt to real-world environment. This paper gives a mathematical formulation for A2E-CVRP and derives a lower bound for it. The lower bound is used for deriving an upper bound subsequently, which is also an approximate solution of A2E-CVRP. Computational results on benchmark instances show that the A2E-CVRP outperforms the classical 2E-CVRP in the costs of routes.

Statistical modeling for Bayesian extrapolation of adult clinical trial information in pediatric drug evaluation

Children represent a large underserved population of “therapeutic orphans,” as an estimated 80% of children are treated off‐label. However, pediatric drug development often faces substantial challenges, including economic, logistical, technical, and ethical barriers, among others. Among many efforts trying to remove these barriers, increased recent attention has been paid to extrapolation; that is, the leveraging of available data from adults or older age groups to draw conclusions for the pediatric population. The Bayesian statistical paradigm is natural in this setting, as it permits the combining (or “borrowing”) of information across disparate sources, such as the adult and pediatric data. In this paper, authored by the pediatric subteam of the Drug Information Association Bayesian Scientific Working Group and Adaptive Design Working Group, we develop, illustrate, and provide suggestions on Bayesian statistical methods that could be used to design improved pediatric development programs that use all available information in the most efficient manner. A variety of relevant Bayesian approaches are described, several of which are illustrated through 2 case studies: extrapolating adult efficacy data to expand the labeling for Remicade to include pediatric ulcerative colitis and extrapolating adult exposure‐response information for antiepileptic drugs to pediatrics.     

协调对华经贸政策的角色：从总统到中美高层经济对话

冷战后,美国在对华经贸政策的制定过程中,包括总统、国会和各行政部门在内的政策主张不一,不时发生对抗,反映出其部门间协调性机制的缺位。近年来,美国财政部牵头下的中美战略经济对话和国务院领导下的中美高层对话构成了中关经济对话的新型机制,弥补了美方对华经贸政策制定中用以协调本国国内各部门政策立场的制度性缺陷,为稳定和助推两国经贸发展提供了一个非常必要的有利机制。     

论高等教育分层下影响教学型本科院校毕业生就业的因素

当今中国高等教育体系是以金字塔形状成层分布的.在本科以上的普通高等院校中,研究型等实力雄厚的大学居于这个层级的上部,而教学型本科院校则居于这个层级的底端.在这种状况下,国家的就业政策、人才市场体制、高校的社会资本以及教学型本科院校自身的专业设置等,则形成了影响教学型本科院校毕业生就业的主要因素.了解这些因素,对于促进教学型本科院校毕业生顺利就业具有重要的理论和实践意义.

“双师型”人才培养模式的构建与实践

“双师型”人才是师范院校培养的具有教师资格和能力又具备相关专业知识技能的应用型人才。笔者就“双师型”教师的建设培养途径、素质要求提出了看法。基于社会对专业“双师型”人才需求发展的需求,结合河北科技师范学院教学实践,指出了“双师型”人才培养模式的目标内涵,提出了“双师型”人才培养“主修＋辅修”、“理论＋技能”、“国内＋国外”、“校内教育＋校外教育”、“学年学分制＋完全学分制”为主体的人才培养模式。对“双师型”人才培养模式的教学体系建设也进行了探讨。

Quasi-minimax estimation in the general linear regression model

This paper is mainly concerned with minimax estimation in the general linear regression model y=Xβ+ε$y=X\beta +\epsilon$ under ellipsoidal restrictions on the parameter space and quadratic loss function. We confine ourselves to estimators that are linear in the response vector y  . The minimax estimators of the regression coefficient β$\beta$ are derived under homogeneous condition and heterogeneous condition, respectively. Furthermore, these obtained estimators are the ridge-type estimators and mean dispersion error (MDE) superior to the best linear unbiased estimator b=(X^′W^-1X)^-1X^′W^-1y$b=(X^{\prime }{W}^{-1}X{)}^{-1}{X}^{\prime }{W}^{-1}y$ under some conditions.
