百年传承 再续新辉——访德国海德汉（天津）光学电子有限公司总经理贾江扬先生

相信许多国内的读者和我一样，起初多是从一些知名企业的口中了解到德国海德汉公司及其产品的。在采访德国海德汉（天津）光学电子有限公司总经理贾江扬先生（以下简称贾总）之前，我对海德汉的印象是：他是一家专做精密测控系统的专业企业，产品单一但技术含量应该算得上是行业领先。对贾总的采访，让我对海德汉有了更加全面深入的了解，同时也对“德国制造”以及象贾总这样有过多年留学德国经历现在作为德资企业（主要是制造企业）代表在中国市场发展的归国人员的了解更深了。     

ADC量化位数对阵列天线GNSS接收机的影响

在处理全球卫星导航系统（Global Navigation Satellite System,GNSS）卫星信号时,针对模数转换器（Analog-to-Digital Converter,ADC）量化位数不同导致输出的信号信噪比下降的问题,推导了阵列天线波束形成后输出信号的信噪比理论计算模型,分析了ADC量化位数对阵列天线抗干扰GNSS接收机的性能影响。在7阵元天线且ADC量化位数为10的条件下,理论模型分析和数据仿真结果表明最大抗干扰能力约为85 dB。通过确定ADC量化位数与抗干扰GNSS接收机抗干扰能力之间的关系,其结论为工程应用中抗干扰GNSS接收机的ADC选型和设计提供了理论依据。

隐藏的收入：住房公积金制度与居民消费升级

在构建“双循环”的新发展格局下，从住房公积金“隐藏”的收入视角探讨居民消费升级具有重要现实意义。文章基于2015年和2017年中国家庭金融调查数据（CHFS），实证研究了住房公积金对居民消费升级的影响效应。研究结果表明：（1）从总体上看，住房公积金显著促进了居民生存型消费和发展享受型消费，且对后者的影响程度更高；（2）从异质性上看，住房公积金对低收入群体和中西部地区居民消费升级的促进作用更大；（3）从影响机制上看，住房公积金通过家庭住房的财富效应成为促进居民消费升级的重要驱动力。文章认为在改革和完善住房公积金制度的背景下，要高度重视其“隐藏”的收入功能，在持续发挥好其住房保障功能的同时，也需充分释放其在促进居民消费升级方面的政策外部性。

Women in Management in Thailand: Advancement and Prospects

Thailand has experienced rapid economic growth over the past two decades. Economic expansion has contributed to an increase in demand for managers and professionals. Changes in legislation to promote gender equality in employment and educational opportunities for women have been implemented. These changes have contributed to Thai women's improved status. The aim of the paper is to assess this progress of women in management in Thailand. There is some evidence suggesting that social class, in addition to education, may play an important role in explaining Thai women's advancement to managerial positions. The contribution examines the changes in legislation and the influence of cultural values, education, and gender on women's access to managerial positions. It identifies the barriers to women's progress and pays attention to social class as another key determinant of women's advancement in management.     

发展我国农地金融的现实障碍及对策探讨

在我国推进城镇化加速发展的过程中,土地不但要作为农民最重要的生产资料,也要成为农民最重要的财富来源,农村土地制度的创新和发展,是未来中国经济制度红利释放的关键点之一,也是我国经济继续前进的重要动力。我国发展农地金融既具有相当程度的可行性,也面临着许多制约因素,其主要体现在农地抵押存在法制障碍,缺乏完善的农地使用权流转机制,缺乏公平科学的农地估价体系,农业保险存在缺位,农村社保发展不完善等方面。发展农地金融服务,国家必须完善农地法律体系,创新农村土地流转机制,建立科学的农地价格评估体系,加大农业保险建设,建立完善的农村社会保障体系等。     

A nonconscious processing explanation of consumer response to product design

Even though there is an established body of research concerning nonconscious memory processes and how they may influence preference formation, the importance of this work for understanding consumers' responses to product designs has been largely overlooked. Although evidence that product design can have a significant influence on consumers' reactions to products continues to grow, the process(es) by which responses to designs are formulated has received relatively little attention. The primary purposes of this article are to develop a nonconscious processing explanation of consumer response to product design and to focus attention on the area of design processing. A conceptual basis for understanding product design response formation is provided by research relating to various aspects of nonconscious processing (e.g., mere exposure, implicit learning). The implications of the proposed approach for consumer behavior and marketing are explored. Finally, several suggestions for future research directions are discussed. © 1999 John Wiley & Sons, Inc.     

Hope,hopelessness, and coping: A framework for class‐distinctive cognitive capital

Evidence that a variety of psychological dispositions vary systematically with social class has been reported in the marketing literature over the last 50 years. However, recent work has been extremely limited. Research progress has been stifled because of poor conceptual specification and lack of an integrative framework capable of grounding these dispositions in theory. This article draws upon the psychology of coping—specifically harnessing hope/hopelessness theories—to develop a much‐needed framework. This will facilitate clear conceptual specification of the psychological dispositions where social class distinctions have been proposed, and specify the relations between each of the dispositions. The term cognitive capital is introduced to capture the idea that one's mix of psychological dispositions operates as a system that can be thought of as an important type of resource that is gradationally distributed with social class level. This cognitive‐capital system impacts life chances and quality‐of‐life outcomes via the predominant pattern of coping responses that are employed in dealing with the many adversities, threats, and challenges that life typically presents. The framework provides academics with a vehicle to progress understanding of these psychological phenomena, marketing communicators with an enriched picture of class‐based distinctions, and public policy makers with an understanding of levers that contribute to social inequality. © 2004 Wiley Periodicals, Inc.     

The future of the ACP countries

The record to date of trade and development cooperation between the European Union and the ACP countries has been rather disappointing. Evidently, neither the non-reciprocal trade preferences granted to the ACP countries nor the support for development projects have led to much progress in terms of economic and social development. Can the implementation of the EU's present reform proposals be expected to safeguard the future of the Lome system and of the ACP countries in the new millenium?     

Alex Cowan & Sons Ltd,Papermakers, Penicuik: a Scottish case of Weber's Protestant Work Ethic

This study examines Weber's Protestant Work Ethic and its power in explaining the business ethos and progress of a leading Scottish papermaking firm, Alex Cowan & Sons Ltd. of Penicuik, which existed independently from 1779 to 1965. Beginning with a summary of the Protestant Work Ethic, as outlined in Weber's thesis of 1904–06, a review of key debates around it is given, followed by details of some recent works which demonstrate its continuing relevance for historical scholars as well as the shortcomings of some recent studies which have sought to test it in detail. A brief outline of the business progress of Cowan's papermaking business then follows, after which key aspects of Weber's thesis are tested against the firm's experience. The study concludes that Weber's thesis adequately describes the motivation and progress of the firm and its owners, providing detailed empirical evidence which supports the Weber thesis and justifies further detailed studies.
