基于B/S的物流信息系统设计与实现

近年来,随着网络技术不断发展,尤其是基于Web的信息发布和检索技术、Java计算技术以及网络分布式对象技术的飞速发展,导致了很多应用系统的体系结构从C/S结构向更加灵活的B/S多级分布结构演变,使得软件系统的网络体系结构跨入一个新阶段.本文系统地分析了B/S结构的特点和现状,将其应用到物流信息系统的开发中,并客观地对应用B/S结构的物流信息系统的前景和优势进行了阐述.     

Managerial Problem-Solving Styles: A Cross-Cultural Study

ABSTRACT

The literature suggests that North American business-people differ from their Latin American counterparts with respect to specific behavioral traits. Our particular interest is in problem solving and in effecting changes in behavior to achieve better problem-solving capability. The purpose of the present study is to assess whether there are differences in problem-solving styles between two culturally different groups of managers registered in MBA Programs: Anglo American and Latin American. Using Kolb's (1984 2006) Learning Style Inventory, it was found that Anglo American managers tended to be relatively action-oriented, “Convergers” (they emphasize decision-making and use deductive reasoning), while Latin American managers tended to be reflection-oriented, “Assimilators” (they emphasize planning and like to create models in their analyses) in their problem-solving styles. The positive and negative aspects of each style are discussed and suggestions for improved decision-making are offered.

RESUMEN. La literatura sugiere que los empresarios norteamericanos difieren de sus contrapartes latinoamericanos, en lo que atañe a ciertos trazos comportamentales específicos. Nuestro interés particular se orienta a la solución de problemas e implementación de cambios comportamentales, con el propósito de adquirir habilidades específicas para la solución de problemas. El propósito de este estudio es evaluar si existen diferencias entre los estilos empleados para solucionar problemas entre diferentes grupos culturales de gerentes matriculados en Programas MBA angloamericanos y latinoamericanos. Usando el sistema de estilos de Kolb (1984 2006) denominado Learning Style Inventory, descubrimos que los gerentes angloamericanos tienden a orientarse con bastante frecuencia en la acción, los llamados ‘Convergentes’ (que hacen hincapié en la toma de decisiones y el uso del razonamiento deductivo), mientras que los gerentes latinoamericanos tienden a volcarse a la reflexión, los llamados ‘Asimiladores’ (que hacen hincapié enplanear y les gusta crear modelos en sus análisis), como característica de sus estilos para solucionar problemas. Discutimos los aspectos positivo y negativo de cada estilo, y hacemos sugerencias para mejorar la toma de decisión.

RESUMO. A literatura sugere que os homens de negócios norte-americanos diferem de seus colegas latino-americanos em traços comportamentais específicos. Nosso interesse particular recai sobre a resolução de problemas e a introdução de mudanças de comportamento para obter uma melhor capacidade de resolução de problemas. O objetivo deste estudo é avaliar se existem diferenças nos estilos de resolução de problemas de dois grupos culturalmente diferentes de gerentes matriculados em cursos de MBA: anglo-americanos e latino-americanos. Utilizando o inventário LSI (learning style inventory) de Kolb (1984 2006), constatou-se que os gerentes anglo-americanos tendiam a ser relativamente orientados para a ação, “convergentes” (eles enfatizam a tomada de decisões e o raciocínio dedutivo), enquanto os gerentes latinoamericanos tendiam a ser orientados para a reflexão, “assimiladores” (eles enfatizam o planejamento e gostam de criar modelos em suas análises) em seus estilos de resolução de problemas. Os aspectos positivos e negativos de cada estilo são discutidos, e sugestões para melhorar a tomada de decisões são oferecidas.     

电力载波技术在实验室工作台控制中应用

近年来随着我国制造业得到了长足发展,随着2009年全球经济危机席卷全球,我国制造业也面临着经济结构调整,技术产业也面临着升级。这就需要大量的高素质技术工人,如今为培养大量的高素质技术工人,政府、企业以及学校也在不断加大投入用工业现场的一线设备来训练从业者。但作为缺乏必要专业职业素养的普通劳动者在接触电气设备时,用电安全是一个不可忽视的重要问题。旨在利用电力载波控制技术对从事电气化实作训练的工作台进行有效控制,大幅减少了综合布线的工作量,提高了控制的可靠性,从而实现了对工作台的智能化、远程化安全控制。     

Vertical Specialization and Trade Growth in Northeast Asia

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO.

Research & development and growth: A Bayesian model averaging analysis

We examine the effect of research and development (R&D) on long-term economic growth using the Bayesian model averaging (BMA) to deal rigorously with model uncertainty. Previous empirical studies, which applied BMA, investigated the effect of dozens of regressors on long-term growth, but they did not examine the effect of R&D due to data unavailability. We extend these studies by proposing to capture the investment in R&D by the number of Nobel prizes in science. Using our indicator, the estimates show that R&D exerts a positive effect on long-term growth. This result is robust to many different parameter and model prior structures as well as to alternative definitions of R&D indicator.

基于 TCP/IP 的远程数字监控系统

根据美国国家经济研究局（NBER）的最新宣布,美国经济自2001年3月已经进入衰退。本文认为,美国此次衰退是难以避免的,这是经济周期的必然规律,由于此前虚拟经济与实体经济的发展脱离,形成泡沫,那些过剩的资本终究会退出,于是造成人们心理预期的过度反应,消费和投资需求出现大幅萎缩,而恐怖袭击事件则加速了衰退的进程。对中国而言,美国衰退的影响是利弊兼有,主要表现在出口、引资、经济格局等方面。     

Farmers' Preference for Farming: Evidence From a Nationally Representative Farm Survey in India

Using data from a nationally representative farm survey in India, we have analyzed Indian farmers' stated preference for farming as a profession. Findings show that more than 40% of farmers dislike farming as a profession because of low profits, high risk, and lack of social status, yet they continue with it owing to a lack of opportunities outside agriculture. Farmers who express a preference for moving out of agriculture are mostly those with small landholdings, poor irrigation facilities, fewer productive assets including livestock, and follow a cereal‐centric cropping pattern. They also have relatively lower access to credit, insurance, and information, and are weakly integrated with social networks such as self‐help groups and farmers' organizations. Importantly, the disinclination for farming, conditional on other covariates, is not significantly differentiated by caste, an important indicator of social status in rural India. Yet, within a caste group, the dislike for farming moderates with larger landholdings.
