周跳探测法在北斗精度定位中的应用研究

介绍了北斗卫星导航系统的发展现状以及北斗卫星的组成,运用载波相位测量卫星信号,得出卫星观测过程中存在卫星周跳现象。在此之后,解析了该卫星导航精度定位的误差来源,一共能够分成三种不同的类型,分别指的是：与该卫星自身有关联的误差;与其信号传播路径有关联的误差;与接收机以及测站有关联的误差。在此步骤结束之后,剖析了周跳的定义与特性,除此之外也分析了周跳对精密定位带来的影响。最终,通过仿真方法得到了有无周跳状况下的高次差法的影响。     

“德合”船基于MOSES软件的DP作业分析

结合“德合”船DP动力定位系统,以康斯博格DP吊重测试文件为基础,基于MOSES软件对DP吊重测试过程中船舶关键数值进行模拟分析。建立了基于Moses软件的船舶模型及计算模型,对吊重过程中船舶吃水变化进行分析,选择典型吃水给到水动力模型中计算DP动力响应。从计算结果可以看出,随着吊机受力增加,船舶吃水逐渐增加,DP系统输出功率明显增加且对应关系明显。此计算结果为“德合”船DP测试安全进行提供数据支持,该计算模型也可以为以后海上DP吊装作业积累数据经验并提供参考。

美国住房反抵押贷款及引入我国可行性评析

住房反抵押贷款是重要金融创新,在发达国家变得越来越流行。它是居民以自有产权作为抵押,定期向金融机构取得的主要用于养老费用的贷款。反抵押贷款提高了住房的流动性,对提高老人生活质量有积极作用。从美国反抵押贷款发展的特点、存在问题来看,反抵押贷款业务在我国有一定的需求潜力。同时新业务在我国的市场必须正确定位,才能将潜在的需求转化为现实的市场。     

The industrial brand personality scale: Building strong business-to-business brands

To remain distinct and build strong business relationships in a competitive business-to-business (B2B) environment, an increasing number of industrial marketers attempt to exploit the potential of branding. However, brand management in the industrial sector is still at its starting point. For this reason, the authors introduce the concept of brand personality to industrial markets. Based on a series of qualitative and quantitative studies, the authors develop and validate an Industrial Brand Personality Scale. Furthermore, they examine whether brand personality perception differences exist among different types of industrial transactions and among different members in the buying center. The analysis yields a framework for theoretical discussion and provides B2B managers with a tool to build strong B2B brands in an increasingly competitive industrial market.     

Code and conduct in French cuisine: Impact of code changes on external evaluations

We study the effects of organizational code‐preserving and code‐violating changes on external evaluations by third parties—an essential but under‐studied strategic outcome. We define code‐preserving changes as a variation in the firm's product range that preserves the social code within which the firm positions its offering. By contrast, a code‐violating change corresponds to a variation in the product range that breaks with past codes and embraces another social code. Our analyses of French haute cuisine restaurants show that code‐preserving changes and code‐violating changes have positive effects on external evaluations. Both effects decline with prior evaluations received by the organization, but only the effect of code‐violating changes is reduced with age. Moreover, external evaluations improve when restaurants undertake more code‐preserving changes than their direct competitors but decline when they make more code‐violating changes than competitors. These results enable us to derive implications for research on strategic change, strategic groups, and strategic social positioning. Copyright © 2007 John Wiley & Sons, Ltd.     

Influence of country and company characteristics on international business decisions: A review,conceptual model,and propositions

This research advances four propositions and a conceptual model of country and company characteristics influencing key International Business Decisions (IBDs). The IBDs in this study are country selection and evaluation, entry mode, segmentation-targeting-positioning, and the marketing mix – the first two in the international business domain, and the latter two in the international marketing field. The conceptual model and related four propositions are advanced, based on an extensive literature review and subsequent in-depth review of 169 published research papers on major IBDs and their determinants, namely, country characteristics, including opportunities, risks, and various distances between the host country and home country, and company characteristics, which include international business experience, assets/resources, and expansion/growth strategies. Managerial implications and directions for future research are discussed.     

Supporters’ Perceptions of Benefits Delivered by Different Charity Activities

Donating time and money are traditional ways individuals support charities. Other support activities include buying charity products, attending events, or sponsoring others. The proliferation of activities means that charity marketers often face difficult decisions when designing a portfolio of support-generating activities. This research draws on the social exchange theory to examine 11 charity-support activities from the supporter’s perspective. Drawing on Australian data from a survey of 248 supporters of a wide range of charities, we use correspondence analysis to map each activity against four benefit dimensions (material, social, expressive, and personal commitment). We quantify overall supporter perceptions of benefits delivered by engaging in each activity and use multinomial logistic regression to identify how past experience can shape perceptions of activities. We discuss academic and managerial implications, including whether or not specific attributes are more useful to recruit or to retain supporters.     

Positioning strategies and congruence in the positioning of high‐end indigenous and foreign retailers in sub‐Saharan Africa: An illustration from Ghana

This article examines the employment of positioning strategies through the lens of international retailing for assessing congruence in the positioning of both indigenous and foreign retailers in Ghana. Six retailers—three indigenous and three foreign—are examined in a triangulated method, each through an in‐depth case study. The results show that the dominant positioning strategies consistently pursued by both indigenous and foreign retailers in Ghana are “service,” “reliability,” and “attractiveness.” Although indigenous retailers (relative to their foreign counterparts) employ more strategies, the majority of foreign retailers exhibit close‐to‐ideal congruence among managers' intentions, actual practice, and customers' perceptions. The findings show that foreign and indigenous retailers pursue varying positioning strategies in the marketplace, further complementing the utility of Western‐developed typologies of positioning strategies in a sub‐Saharan African marketplace. Moreover, the results reveal how indigenous retailers have embraced branding, further attesting to the changing and competitive nature of the Ghanaian marketplace.
