个人网上银行客户体验基本构成要素间作用关系实证研究

客户体验与客户体验管理能够解决个人网上银行的同质化问题。本文旨在探讨个人网上银行客户体验基本构成要素间的作用关系。通过对2000多位客户的问卷调查,本文采用结构方程模型,对体验感知、体验期望和感知价值等个人网上银行客户体验基本构成要素之间的作用关系以及安全、使用成本等因素对体验感知的作用关系进行实证研究,发现体验感知对感知价值、体验期望对体验感知有正向的影响;体验期望对感知价值有负向影响;安全、使用成本、易用、速度与稳定、品牌信任、功能满足、客户服务和便利等对体验感知有正向影响;而营销活动对体验感知没有显著影响。     

基于数据库的功能翻译理论视角下的软新闻翻译策略——以《北京周报》为例

软新闻英译的具体方法主要有增译、删减、重构和解释。以功能理论为框架,根据报纸的通用分类方式为标准,收集和整理了《北京周报》34则汉英对照新闻,通过分类建数据库的方式对七类新闻进行了定性和定量研究。研究结果表明:不同类型的软新闻,翻译方法侧重点是不同的,其最终目的就是使译文被接受,以达到对外交流和宣传的效果。     

高校教学基本状态数据的网络化管理

利用数据库技术,建立从院（系）、学校,到省（市、区）、教育部的四级数据库系统,有助于准确把握教学运行好状态,有利于教育宏观决策,有利于提高教学质量。该数据库系统可以实现数据采集、统计、分析和发布的功能,能够满足教学管理的需要。建立基于数据库技术的教学状态管理体系是为深化高等教育改革的有效途径。     

Online scheduling on parallel machines with two GoS levels

This paper investigates the online scheduling problem on parallel and identical machines with a new feature that service requests from various customers are entitled to many different grade of service (GoS) levels. Hence each job and machine are labeled with the GoS levels, and each job can be processed by a particular machine only when the GoS level of the job is not less than that of the machine. The goal is to minimize the makespan. In this paper, we consider the problem with two GoS levels. It assumes that the GoS levels of the first k machines and the last m−k machines are 1 and 2, respectively. And every job has a GoS level of 1 alternatively or 2. We first prove the lower bound of the problem under consideration is at least 2. Then we discuss the performance of algorithm AW presented in Azar et al. (J. Algorithms 18:221–237, 1995) for the problem and show it has a tight bound of 4−1/m. Finally, we present an approximation algorithm with competitive ratio .

Almost optimal solutions for bin coloring problems

In this paper we study two interesting bin coloring problems: Minimum Bin Coloring Problem (MinBC) and Online Maximum Bin Coloring Problem (OMaxBC), motivated from several applications in networking. For the MinBC problem, we present two near linear time approximation algorithms to achieve almost optimal solutions, i.e., no more than OPT+2 and OPT+1 respectively, where OPT is the optimal solution. For the OMaxBC problem, we first introduce a deterministic 2-competitive greedy algorithm, and then give lower bounds for any deterministic and randomized (against adaptive offline adversary) online algorithms. The lower bounds show that our deterministic algorithm achieves the best possible competitive ratio. The research of this paper was partially supported by an NSF CAREER award CCF-0546509.

Motivations for self-assembling into project teams

This study investigates the self-assembly mechanisms of ad hoc project teams using a bipartite network perspective. Individuals and projects are modeled as two types of nodes and team membership as relations between them. This approach enables us to investigate factors that impact voluntary team assembly at the individual, dyadic, and team levels simultaneously. Using Exponential Random Graph Models (ERGM/p*), we study players’ combat teams in a Massively Multiplayer Online Role-Playing Game (MMORPG) as a case of self-assembled project teams. Empirical results show that individuals are motivated to join ad hoc teams to complete difficult projects but not projects with long durations. We also found that individuals tend to collaborate with specific teammates who have complementary skills, those who have similar age or skill level, and those who are affiliated with the same organizational entity.     

Oracle数据库中SQL查询优化的研究

现代社会科技的发展日新月异,各行各业都开始应用计算机管理软件提升工作效率。数据库的设计是各个管理软件的设计与实现中必不可少的,很多领域都有数据库信息存储与信息处理的技术应用。Oracle数据库是当前比较流行的数据库,SQL作为通用的、功能极强的通用数据库语言如果得到更好的优化,将使软件性能更加优化。本文主要从对于Oracle数据库SQL查询优化的重要性着手,从索引以及查询语句等优化方式进行分析,并且总结了一些Oracle数据库SQL查询优化技巧。

School Social Work Information Systems (SSWIS): A Relational Database for School Social Workers

SUMMARY

After a review of their information management system, the Winston-Salem/Forsyth County School Social Work Office began a process to improve data collection and information management. The result was the creation of the School Social Work Information System, a relational database designed and developed by the school social workers themselves. This article reviews the process of evaluating existing systems, developing and implementing the new system, evaluation and continued development of the new system, and implications for further social work practice. This article is intended to provide the school social worker with the necessary information to develop similar systems.
