虚拟仪器技术对知识创造的影响研究

仪器作为现代科学研究的核心组成部分，在很大程度上决定了科学知识的产出。虚拟仪器技术对知识创造产生了深远影响。“软件就是仪器”的理念使得传统仪器、测量观念以及仪器作为科技黑箱的内涵和功能发生了质的变化。虚拟仪器在集成大量编码知识的同时更多地集成了主体的隐性知识，虚拟仪器技术通过对主体知识体系的重塑影响了知识创造。主体只有通过长时间、复杂的学习和使用过程才能充分发挥虚拟仪器技术在知识创造中的优势，实现编码知识和隐性知识的共同增长。     

Analysis of Korean millennials’ travel expenditure patterns: an almost ideal demand system approach

ABSTRACT

Generational cohorts can differ in their consumption patterns and preferred travel behavior. As the millennial generation represents an important economic force and influences new consumption trends, this study utilizes nationwide data and almost ideal demand system (AIDS) approach to examine expenditure patterns of Korean travelers during holidays. In this process, the joint effects of travel-related characteristics are also examined. The results of the AIDS estimation on data from 871 domestic travelers reveal significantly different travel expenditure patterns for cohorts. The findings contribute to furthering the understanding of how different generational cohorts allocate their travel budgets to respective travel expenditure categories.

Treatment patterns,complications, and direct medical costs associated with ankylosing spondylitis in Chinese urban patients: a retrospective claims dataset analysis

Aim: To describe treatment pattern, complications, and direct medical costs associated with ankylosing spondylitis (AS) in Chinese urban patients.

Methods: The 2013 China Health Insurance Research Association (CHIRA) urban insurance claims database was used to identify patients with AS. The identified patients were stratified by AS treatments for the comparisons of well established AS-related complications and direct medical costs. Conventional regression analyses adjusted the collected patient baseline characteristics to confirm the impact of treatments on complications and direct medical costs.

Results: Of the identified 1299 patients with AS, 18.0% received non-steroidal anti-inflammatory drugs (NSAID), 11.2% received immunosuppressant, 48.2% received NSAID plus immunosuppressant, 4.6% received biologic agents, and 17.9% received medications without indication for AS. Biologic group was associated with the lowest proportion of AS-related complications (8.3%) that was confirmed by multiple logistic regression analysis (odds ratio = 0.200, p?=?.017). The biologic group was also associated with highest direct medical costs (median: RMB?=?14,539) that were confirmed by the multiple generalized linear model (coefficient = 1.644, p?Conclusions: Biologics were not commonly used for AS in Chinese patients likely due to their high cost. Future studies are needed to confirm the potential long-term clinical benefits associated biologic treatment for AS.     

The integrated yard truck and yard crane scheduling problem: Benders’ decomposition-based methods

This paper proposes a novel integrated model for yard truck and yard crane scheduling problems for loading operations in container terminal. The problem is formulated as a mixed-integer programming model. Due to the computational intractability, two efficient solution methods, based on Benders’ decomposition, are developed for problem solution; namely, the general Benders’ cut-based method and the combinatorial Benders’ cut-based method. Computational experiments are conducted to evaluate the effectiveness of the proposed solution methods.     

CHANGE for a New Economic Structure？

Opportunity in the financial crisis？
For a long time, China＇s fast economic growth is heavily dependent on growth of exports, particularly dependent on exports of low value-added, low technological products. Although the policy-makers and scholars are aware of the importance and necessity of industrial structure improvements since 1992, it is hard to have a real incentive to promote economic restructuring under rapid economic growth.
