国际垂直专业化、贸易分工模式与福利

在标准贸易理论框架下,通过引入垂直专业化和片段化生产,从理论上分析了国际垂直专业化对各参与国贸易分工模式的拓展及对国民和要素所有者福利的影响。研究结果表明,垂直专业化使一国比较优势由产品间深入到产品内部,进而使得各参与国贸易分工模式更为复杂,一国贸易模式可能会与该国原有的传统比较优势相悖;垂直专业化增进了世界福利,但在特定分工模式下可能会损害一国的福利,并且对于不同要素所有者福利的影响是不确定的。

吴仓堡油区三叠系油层体积压裂技术探索研究及应用

吴仓堡油区三叠系油层有长6、长8、及长9等开采层系,均具有低孔、低渗透、低压、低产等特征,一般不经压裂无自然产能,但是常规水力压裂改造后,单井产量低、产量下降快、油田稳产形势严峻,严重制约了三叠系油藏的有效开发。本文针对三叠系主力油层长6、长8和长9为主要研究对象,结合吴起油田勘探开发过程中的水力压裂改造实践经验,借鉴国内外低渗透、低压致密油层改造先进技术理念,以储层研究为基础,分析了体积压裂的增产机理及在吴仓堡油区开展体积压裂的可行性,探索了吴仓堡油区三叠系油层体积压裂的工艺设计模式,为吴起油田低渗透、低压致密油层开展体积压裂提供了有益的参考。     

A literature review on business process modelling: new frontiers of reusability

Business process modelling (BPM) has become fundamental for modern enterprises due to the increasing rate of organisational change. As a consequence, business processes need to be continuously (re-)designed as well as subsequently aligned with the corresponding enterprise information systems. One major problem associated with the design of business processes is reusability. Reuse of business process models has the potential of increasing the efficiency and effectiveness of BPM. This article critically surveys the existing literature on the problem of BPM reusability and more specifically on that State-of-the-Art research that can provide or suggest the ‘elements’ required for the development of a methodology aimed at discovering reusable conceptual artefacts in the form of patterns. The article initially clarifies the definitions of business process and business process model; then, it sets out to explore the previous research conducted in areas that have an impact on reusability in BPM. The article concludes by distilling directions for future research towards the development of apatterns-based approach to BPM; an approach that brings together the contributions made by the research community in the areas of process mining and discovery, declarative approaches and ontologies.     

An Exploratory Study of the Propensity for South Koreans to take Cruises: Investigating Koreans' Perceptions of Cruise Ship Travel

The purpose of the present study was to examine Koreans' perceptions of cruise ship travel to ascertain the potential for future development of that tourism segment. An understanding of Koreans' perceptions is essential for determining the potential of the Korean cruise market. Using survey data, the study investigated Koreans' knowledge level, willingness and desired travel patterns regarding cruise ship travel. Findings from the study can assist practitioners to enhance their comprehension of Koreans' perceptions and behaviors concerning cruise ship travel. Copyright © 2011 John Wiley & Sons, Ltd.

Cultural differences in consumer socialization: A comparison of Chinese–Canadian and Caucasian–Canadian children

Based on the extant literature on the cultural/subcultural differences in socialization goals and parental practices in the childrearing process, this study compares Chinese–Canadian and Caucasian–Canadian families with respect to three issues central to consumer socialization – family communication patterns, children's consumer decision-making styles, and children's influence in family purchase decisions. Some significant results include: (1) Chinese–Canadian children perceived both of their parents as more socio-oriented than Caucasian–Canadian children perceived theirs whereas no significant between-group difference was found on the perceived level of concept-orientation for either parent; (2) Chinese–Canadian children, relative to their Caucasian–Canadian counterparts, exhibited more utilitarian and confused-by-overchoice consumer decision-making orientations but less social/conspicuous and impulsive orientations; and (3) Chinese–Canadian children exercised greater purchase influence than their Caucasian–Canadian counterparts for the adolescent ‘convenience’ product category but no difference was found for the adolescent ‘durable’ product category.

Examining and identifying the determinants of travel expenditure patterns

This study examined the effects of socio‐demographic, travel‐related and psychographic variables on travel expenditures. The travel expenditure categories examined include lodging, meals and restaurants, attractions and festivals, entertainment, shopping, transportation and total expenditures. The results of the study provide a more comprehensive and holistic picture in the search of travel expenditure patterns based on multiple independent variables. This study reveals that, among the three groups of variables examined, income and trip‐related characteristics were the most influential variables affecting tourism expenditures. Discussions and implications are also provided based on the study results. Copyright © 2006 John Wiley & Sons, Ltd.     

我国公共卫生投入方式的转变

通过对公共卫生投入现状和问题的考察,发现存在投入主体单一、投入总量不足、投入结构不合理、投入效果不明显等问题,提出了应由政府单一投入向市场政府多元化投入转变,由以地方为主投入向中央地方共担投入转变,由维持运营投入向扩大服务投入转变等结论,顺应公共卫生投入由行政管理式向市场服务式投入的转变趋势。
