Our study investigated the effect of team knowledge on new product development (NPD). By investigating 207 NPD projects, we found that the declarative and procedural knowledge of the team and their use of IT had a positive influence on the team's knowledge base; and that the higher the functional diversity of the project team, the greater their overall knowledge. We also found that team knowledge positively impacted new product creativity and success in the market place. 相似文献

Porter sites have tried to increase their business potentials by helping users easily engage in diverse online activities such as search, entertainment, online communities, and others. Knowledge search engine is one of the most successful killer applications increasing user loyalty. However, most studies have independently focused on search engine technology such as search keyword algorithm, presentation of information and user characteristics such as cognitive style, search experiences, and skill levels. However, these previous studies lack an integrated understanding of causal links among critical factors predicting user motives and intention involving more situation-specific user characteristics. To fill these gaps in the literature, the present study focuses on whether knowledge characteristics such as specialization, preciseness, and diversity, and system characteristics such as interactivity, responsiveness, and communication richness are important in forming user motives and intention. The present study also identifies a moderating role of epistemic curiosity in the links between motives and intention. Two hundred and fifty-five data from Korean university students confirmed that knowledge and services characteristics such as specialty, preciseness, diversity, communication richness improve user motives, which have a positive impact on intention. Epistemic curiosity has a moderating effect on the links between motives and intention. Theoretical and practical implications are discussed in conclusion. 相似文献

Perceiving another person as responsive to one’s needs is inherent to the formation of attachment bonds and is the foundation for safe-haven and secure-base processes. Two studies examined whether such processes also apply to interactions with robots. In both studies, participants had one-at-a-time sessions, in which they disclosed a personal event to a non-humanoid robot that responded either responsively or unresponsively across two modalities (gestures, text). Study 1 showed that a robot’s responsiveness increased perceptions of its appealing traits, approach behaviors towards the robot, and the willingness to use it as a companion in stressful situations. Study 2 found that in addition to producing similar reactions in a different context, interacting with a responsive robot improved self-perceptions during a subsequent stress-generating task. These findings suggest that humans not only utilize responsiveness cues to ascribe social intentions to robots, but can actually use them as a source of consolation and security. 相似文献

Reconfigurable manufacturing systems are designed to deliver exact functionality and capacity that is needed, when it is needed. The reconfigurable machine tool (RMT) plays a pivotal role in the accomplishment of this objective through their built in modular structure consisting of basic and auxiliary modules along with the open architecture software. 相似文献

Organizations are increasingly turning to information technology (IT) to help them respond to unanticipated environmental threats and opportunities. In this paper, we introduce a systematic review of the literature on IT-enabled agility, helping to establish the boundary between what we know and what we don’t know. We base our review on a wide body of literature drawn from the AIS Basket of Eight IT journals, a cross-section of non-Basket journals, IT practitioner outlets, and premier international IS conferences. We review the use of different theoretical lenses used to investigate the relationship between IT and organizational agility and how the literature has conceptualized agility, its antecedents, and consequences. We also map the evolution of the literature through a series of stages that highlight how researchers have built on previous work. Lastly, we discuss opportunities for future research in an effort to close important gaps in our understanding. 相似文献

This study attempts to investigate the online expressive behavior of social media users in China. Specifically, we combine machine learning-based textual analysis with social network analysis to examine the structure and content of the discussion network which formed around the political aspects of food safety issues on China's Twitter-like Weibo. The findings suggest that Weibo-mediated communication space does not serve as an effective forum for deliberative discussion because people of like mind tend to cluster and the factor of emotion predominates. Further statistical analyses of a hand-coded sample show that emotional discussions influence people more than cognitive discussions, with distinct emotions (e.g., anger, fear and sadness) having different effects. A poster's status is also found to matter. We contend that this kind of online civic talk underlines an expressive form of rationality that transcends the dominant bipolar instrumental-communicative dimension for understanding the use of social media in online political discussion. 相似文献

The evolution of manufacturing systems, according to changing internal and external conditions, requires design and assessment
techniques that consider both strategic and financial criteria to evaluate the suitability of the Flexible and Reconfigurable
system solutions in addressing these variations. In this paper, a fuzzy multi-objective mixed integer optimization model to
evaluate RMS investments used in a multiple product demand environment is presented. The model incorporates in-house production
and outsourcing options, machine acquisition and disposal costs, operational costs, and re-configuration cost and duration
for the utilized modular machines. The resulting system configurations are optimized for lifecycle costs, responsiveness performance,
and system structural complexity simultaneously. A complexity metric that incorporates the quantity of information using an
entropy approach is used to represent the inherent structural complexity of the considered system configurations. It accounts
for the complexity of the machine modules in a manufacturing system through the use of an index derived from a newly developed
manufacturing systems classification code, which captures the effect machine types and technologies on the system’s structural
complexity. A metric is proposed to measure the responsiveness ability and efficiency as well as the overall capability of
each machine and effectiveness of machines changeover. The application of the developed planning and assessment model that
incorporates these three criteria is illustrated with a case study where FMS and RMS alternatives were compared. The suitable
conditions for investing in RMS are also discussed.

A system guarantees responsive usage of a channel r if a communication along r is guaranteed to eventually take place. Responsiveness is important, for instance, to ensure that any request to a service be eventually replied. We propose two distinct type systems, each of which statically guarantees responsive usage of names in well-typed pi-calculus processes. In the first system, we achieve responsiveness by combining techniques for deadlock and livelock avoidance with linearity and receptiveness. The latter is a guarantee that a name is ready to receive as soon as it is created. These conditions imply relevant limitations on the nesting of actions and on multiple use of names in processes. In the second system, we relax these requirements so as to permit certain forms of nested inputs and multiple outputs. We demonstrate the expressive power of the two systems by showing that primitive recursive functions–in the case of the first system–and Cook and Misra’s service orchestration language orc–in the case of the second system–can be encoded into well-typed processes. 相似文献
