The Role of Information Technologies in Enhancing R&D–Marketing Integration: An Empirical Investigation

The effective integration of research and development (R&D) and marketing contributes to the development of successful new products. Barriers such as physical separation of R&D and marketing, goal incongruity, and cultural differences hamper the cross‐functional cooperation. However, it may not be either possible or desirable to eliminate the cross‐functional integration barriers in practice. Previous research findings suggest that information technology (IT) can be used to reduce the negative impact of the barriers. This paper examines the moderating role of communication technologies (ITc) and decision‐aiding technologies (ITd) in improving the R&D–marketing integration in new product development. The empirical findings from analyzing data on 171 new product development projects suggest that both IT systems can be used to reduce the negative impact of physical separation, goal incongruity, and cultural differences on R&D–marketing integration. However, effectiveness of the two types of IT differs. While IT_c appears to be more effective than IT_d in overcoming the constraint of physical separation, IT_d is more effective than IT_c in reducing the negative impact of goal incongruity and cultural differences. IT_c is found to have the strongest effect on reducing the negative relationship of physical separation and integration, a less strong effect on cultural differences, and a weak effect on goal incongruity. Conversely, IT_d is found to have a strong effect on goal incongruity. These empirical findings provide guidelines for project managers using a specific IT to address a specific integration barrier. If the major barrier is physical separation, IT_c is the best solution. On the other hand, if the major barrier is goal incongruity, IT_d is the best solution. In addition, it is important for management to note that IT requires more than simply installing computer hardware and software. In addition to investing in those “hard” improvements, project managers should strive to create a supportive “soft” environment by consistently improving members' IT experiences and familiarity. In the process of the continuous development of IT, state‐of‐the‐art technologies should be introduced in a timely manner and be made accessible to all team members. Finally, project managers should frequently observe their industry peers' IT usage to keep up with advances.

The switchover to digital broadcasting in Korea

This study investigates the development of Korean digital TV transition by tracing the interaction between social and technological entities from various perspectives at different developmental stages. A socio-technical analysis examines the dynamic interactions among the stakeholders in the switchover to digital broadcasting, showing how the various actions taken by leading stakeholders affect diverse groups of stakeholders. The overall findings show that Korean digital TV transition is the outcome of a proactive strategy by industry stakeholders and the Korean government's top–down policy of supporting such a transition. It is argued that the policy of a top–down transition, which overlooks coordination among stakeholders, harms consumers and hinders effective and sustainable development. The case of Korea has implications for other countries that are pursuing digital transition strategies.     

谈公路工程监理及质量控制措施

监理在公路工程建设中是一项非常关键的基础性工作,它贯穿整个公路建设的全过程,这项工作若有闪失,给整个工程造成的负面影响是显著的,重则工程报废,少则部分返工。对于监理工程师来说,不仅要有认真、踏实的工作作风和工程建设的专业知识,还必须同时具备监理工作的相关理论基础和实践经验,从而对工程施工进行有效的监控。文章结合我国公路工程监理工作的特点,就公路工程监理过程中一些质量控制问题进行探讨及建议。     

基于Hopfield神经网络的字符识别

噪声字符识别具有很好的应用前景，也是图像后期处理的基础。基于离散Hopfield神经网络的联想记忆能力，通过修整噪声强度将0～9这10个数字和A—Z这26个大写英文字母正确的识别出来。仿真结果表明，当字符被一定的噪声干扰后，仍具有较好的识别效果。
