Proactive postsales service (PPS) refers to a supplier taking the initiative to contact a customer to provide service after a sale is complete. It is argued that PPS leads to faster delivery of service to a broader cross-section of customers than customer-initiated postsales service, or reactive postsales service. The authors argue that mental frames of customers and suppliers engaged in PPS ar...

innovation strategy is the basis of success in innovation and performance improvement. this paper represents a model related to the most important innovation strategies which have a significant impact on performance of industries. then, it examines the relationships between innovation strategies and diversity and development of the performance. so, the empirical research was carried out in iran...

In VANET high speed is the real characteristics which leads frequent breakdown, interference etc. In this paper we studied various Ad hoc routing protocols, Reactive, Proactive & Hybrid, taking in to consideration various VANET parameters like speed, altitude etc in real traffic scenario and evaluated them for various battery models for energy conservation.. The AODV and DYMO (Reactive), OLSR (...

Realistic survivable systems must assume that faults will occur within the system. When a malicious fault is activated, it may work to cause damage and to spread; until the system has recovered from this damage, it will have a lower degree of survivability than it did before the fault occurred. By proactively containing faults that would otherwise spread throughout the system, we can reduce the...

Effective human teams use overlapping shared mental models for anticipating information needs of teammates and for offering relevant information proactively. The long-term goal of our research is to empower agents with such “shared mental models” so that they can be used to better simulate, train, or support human teams for their information fusion, interpretation, and decisions. Toward this go...

Memory for familiar people is essential to understand their identity and guide social interaction. Nevertheless, we know surprisingly little about the structure of such memory. Previous research has assumed that semantic memory for people has a categorical structure, but recently it was proposed that memory for people consists only of associations and lacks any categorical structure. Four exper...

Past research indicates that short-term memory can be immune to the effects of proactive interference (PI). Past research also indicates that immunity to PI is found only in those circumstances where phonemic representations of to-be-remembered items are present and provide discriminative information. The first three experiments demonstrate the existence of a further boundary condition. PI is o...

A large class of routing protocols for MANETs, namely, reactive protocols, employ some form of caching to reduce the number of route discoveries. The simplest form of caching is based on associating a timeout with each cache entry. Such timer-based cache schemes can increase the protocol efficiency. However, if the timeout is not well-tuned, a severe performance degradation arises as entries ar...

tourism development in to geographical areas especially ecotourism, in addition to their economic, social and cultural consequences, will also leave great environmental impacts on geographical locations. if careful preventive and proactive measures in the form of strategy formulation, setting standards and ongoing specific assessments are not taken, destructive effects of ecotourism in an exten...
