打造长白山人口文化的意义与作用

吉林省打造长白山人口文化,是全面做好人口计生工作、统筹解决吉林人口问题的需要。打造长白山人口文化,是对吉林丰富的人口文化资源发掘和提炼的过程,是新型人口文化的构建过程,是现代人口计生工作文明形态的构建过程。它既是传统人口文化与现代文化的一次融合、碰撞与创新的过程,也是对以往文化"缺位"的人口计生工作模式的积极定位。因此,打造长白山人口文化具有重要的理论意义和现实意义。     

A Design Theory Approach to Building Strategic Network‐Based Customer Service Systems*

Customer service is a key component of a firm's value proposition and a fundamental driver of differentiation and competitive advantage in nearly every industry. Moreover, the relentless coevolution of service opportunities with novel and more powerful information technologies has made this area exciting for academic researchers who can contribute to shaping the design and management of future customer service systems. We engage in interdisciplinary research—across information systems, marketing, and computer science—in order to contribute to the service design and service management literature. Grounded in the design‐science perspective, our study leverages marketing theory on the service‐dominant logic and recent findings pertaining to the evolution of customer service systems. Our theorizing culminates with the articulation of four design principles. These design principles underlie the emerging class of customer service systems that, we believe, will enable firms to better compete in an environment characterized by an increase in customer centricity and in customers' ability to self‐serve and dynamically assemble the components of solutions that fit their needs. In this environment, customers retain control over their transactional data, as well as the timing and mode of their interactions with firms, as they increasingly gravitate toward integrated complete customer solutions rather than single products or services. Guided by these design principles, we iterated through, and evaluated, two instantiations of the class of systems we propose, before outlining implications and directions for further cross‐disciplinary scholarly research.     

Barriers to Swift,Even Flow in the Internal Supply Chain of Perioperative Surgical Services Department: A Case Study*

This research analyzes the internal service supply chain of a perioperative surgical services department of a nonacademic community hospital using the theory of swift and even flow as a theoretical lens. Performance data were gathered using an in‐depth case study and it was determined that the swift and even flow constructs did affect flow speed and variance, but did not account for all the effects observed. To understand the need for departments to coordinate their efforts with each other and how this affected flow, further analysis was conducted using insights from Pagell's (2004) theory of internal integration and Gittell's (2002) research about coordinating mechanisms. The findings suggest the need to incorporate a variable measuring supply chain coordination into the theory of swift and even flow.     

Pilot–pivotal trials for average bioequivalence

Before carrying out a full scale bioequivalence trial, it is desirable to conduct a pilot trial to decide if a generic drug product shows promise of bioequivalence. The purpose of a pilot trial is to screen test formulations, and hence small sample sizes can be used. Based on the outcome of the pilot trial, one can decide whether or not a full scale pivotal trial should be carried out to assess bioequivalence. This article deals with the design of a pivotal trial, based on the evidence from the pilot trial. A two-stage adaptive procedure is developed in order to determine the sample size and the decision rule for the pivotal trial, for testing average bioequivalence using the two one-sided test (TOST). Numerical implementation of the procedure is discussed in detail, and the required tables are provided. Numerical results indicate that the required sample sizes could be smaller than that recommended by the FDA for a single trial, especially when the pilot study provides strong evidence in favor of bioequivalence.

时间趋势平稳性检验的带宽选择及其影响

本文将基于最小化两类错误的概率选择带宽的思想引入KPSS检验。文章通过蒙特卡罗仿真实验,对基于最小化均方误差和最小化两类错误概率的KPSS检验的有限样本性质进行了比较;并对中国季度实际GDP对数序列的平稳性进行了检验。结果表明,基于最小化两类错误概率的检验比基于最小化均方误差的检验有更大的水平扭曲,但前者也有更大的检验势;并且在误差项自回归系数小于等于0.5的大多数情形下,基于最小化两类错误概率的检验有更好的有限样本性质;中国季度实际GDP对数序列是带漂移的单位根过程。     

Information Technology and Process Performance: An Empirical Investigation of the Interaction Between IT and Non‐IT Resources*

Drawing on the resource‐based view, we propose a configurational perspective of how information technology (IT) assets and capabilities affect firm performance. Our premise is that IT assets and IT managerial capabilities are components in organizational design, and as such, their impact can only be understood by taking into consideration the interactions between those IT assets and capabilities and other non‐IT components. We develop and test a model that assesses the impact of explicit and tacit IT resources by examining their interactions with two non‐IT resources (open communication and business work practices). Our analysis of data collected from a sample of firms in the third‐party logistics industry supports the proposed configurational perspective, showing that IT resources can either enhance (complement) or suppress (by substituting for) the effects of non‐IT resources on process performance. More specifically, we find evidence of complementarities between shared business–IT knowledge and business work practice and between the scope of IT applications and an open communication culture in affecting the performance of the customer‐service process; but there is evidence of substitutability between shared knowledge and open communications. For decision making, our results reinforce the need to account for all dimensions of possible interaction between IT and non‐IT resources when evaluating IT investments.     

社会工作教学实验设计研究

社会工作实验课程的实验设计以学生操作能力的获得为目的,这样就与作为研究的实验设计迥异。教师进行实验设计的重点在于如何根据课堂内容,设计适当的课堂实验活动,将课堂体验与讲授有机结合,在讲授中巧妙地穿插体验活动。主要通过案例分析、情景模拟、角色扮演等方法,演练典型案例,提升社会工作实务技能,并借助单面镜、视频和音频采集处理系统等实验设备对演练过程进行观察、录制和回放,教师进行点评,角色扮演的双方同学反馈感受,同学之间互相讨论,使角色扮演者和观察者反思自己和他人的行动,关注自己的体验和选择,建构社会工作理论知识和实务操作能力,使学生从中获得专业成长。本文将参考了国外最新的实验室利用方法,从社会工作实验教学设计的角度出发,探索如何设计符合课堂内容,同时又能提高学生学习兴趣的实验,加强实验室的软实力建设,提高实验教学的效果。

社会工作专业“实践教学系统”构想

社会工作是一门应用性的学科,是实务性、操作性取向的专业。社会工作专业人才除了具备一般社会科学和社会工作专业的理论和知识之外,还应树立社会工作的价值理念和掌握社会工作的方法、技能。这就要求必须强化社会工作实务教学,使之贯穿整个社会工作专业教学过程。本文分析和反思了目前影响社会工作专业实践教学实效的问题,从社会工作专业实务性特征入手探讨了＂角色—方式—目标＂相结合的社会工作实践教学系统的设计。该系统通过将＂实验型＂实习模式、＂项目化＂实习模式及＂分类分层化＂实习模式合理、有机地整合起来,为学生提供了适宜的实习条件。
