This study seeks to extend current research by testing a framework for understanding the impact of perceived suppliers' willingness for customization, effective communication, and trust regarding perceived switching costs.

Research data were collected from electronics firms in Taiwan; 281 questionnaires were collected. Structural equation model (SEM) analysis was applied to the data.

The study suggests that perceived trust contributes to perceived switching costs. The perceived willingness of a supplier to customize for a buyer can indirectly impact on perceived switching costs by way of perceived trust toward the supplier. Furthermore, analysis of the direct and indirect effects reveals that effective communication plays a dominant role and has a significant influence on trust and perceived switching costs.

While recent research increasingly examines customer switching costs in terms of antecedents, this study provides greater insight into switching costs from the trust‐forming perspective to ensure customer retention.

The purpose of this paper is to propose a new algorithm for in‐mission trajectories and speed adjustment of multiple unmanned aerial vehicles (UAVs) participating in a mission that requires them to arrive at target location simultaneously with switching and imperfect communication among the vehicles.

This algorithm, programmed at each UAV level, is based on the repeated consensus seeking among the participating vehicles about the time‐on‐target (ToT) through an imperfect inter‐vehicle communication link. The vehicles exchange their individual ToT values repeatedly for a particular duration to pick the highest value among all the vehicles in communication. A consensus confidence flag is set high when consensus is successful. After every consensus cycle with high confidence value, the mission adjustment is carried out by computing difference value between ToT consensus and a threshold value. For the difference values higher than a certain limit, vehicle's trajectory is adjusted by in‐mission insertion of new waypoint (WP) and for lower values the vehicle's speed is varied under allowable limits. The consensus seeking followed by the mission adjustment is repeated periodically to quash the imperfect communication effects.

A mathematical analysis has been carried out to establish the conditions for convergence of the algorithm. The simultaneous arrival of the vehicles subjected to switching communication is achieved only when the union of the switching links during the consensus period enables a vehicle to receive information from all the other vehicles and the switching rate is sufficiently high. This algorithm has been tested in a 6‐degree‐of‐freedom (DoF) multiple UAV simulation environment and achieves simultaneous arrival of multiple fixed wing UAVs under imperfect communication links that meets the aforementioned conditions.

The presented algorithm and design strategy can be extended for other types of cooperative control missions where certain variable of interest is shared among all the vehicles over imperfect communication environment. The design is modular in functionality and can be incorporated into existing vehicles or simulations.

This research presents a new consensus algorithm that repeatedly performs polling of ToT among the vehicles through intermittent communication. The continual nature of consensus seeking covers the weakness of the imperfect communication. A two‐level mission adjustment provides better accuracy in simultaneous arrival at the target location.

Fearing that their voice and SMS business will be substituted by IP‐based services from internet companies, mobile operators are developing various IP multimedia subsystem (IMS) based technologies to enable richer communication services. They reason that since the new rich communication services – such as enhanced presence, group communication and seamless switching between devices and media types within the same communication session – provide secure and more reliable services than those offered by internet companies – Skype, Whatsapp and Google+, for instance – consumers will readily appreciate their services and consequently use them. This paper seeks to address these issues.

To validate these claims, this study analyzes the results of a conjoint survey among 82 respondents in The Netherlands, France and Spain. Are users really willing to adopt these rich communication services and, if so, do issues like reliability, privacy and security impact their decision?

The results indicate that while users are most interested in “group communication” features of rich communication services, they appreciate other services like “switching devices”, “switching media during communication sessions” and “file‐sharing”. Still, for all services, reliability, security and interoperability (i.e. switching between devices) are valued as important requirements.

These findings contribute to the debate on platform competition, as these rich communication services are provided on the basis of the IMS platform, while competing services are offered via an internet base platform.

This paper contributes to the discussion in the mobile telecommunications domain on whether and how operators can counter the threat from internet players that look to take over their voice and SMS business. Theoretically, this paper will contribute both to understanding why users intend to adopt advanced mobile services and creating insight into the consumer‐related factors that drive the war between competing service platforms.

The purpose of this paper is to identify and compare different groups of customers’ perceptions (i.e. stayers, switchers, and heavy switchers) of several loyalty antecedents such as satisfaction, trust, service quality, switching costs, marketing communication, and loyalty itself.

This study was carried out based on data collected through a questionnaire from 353 telecommunication services users in Portugal and using confirmatory factor analysis (CFA) and analysis of variance.

The three types of customers – stayers, switchers, and heavy switchers – clearly differ among themselves. Stayers differ from switchers regarding their communication efforts perceptions, and from heavy switchers in their loyalty, satisfaction, and trust levels. Switchers differ from heavy switchers in their loyalty levels.

Future research should examine differences between customers taking into account the impact of their personality, price sensitiveness, and orientation toward the adoption of new technologies.

As there are several differences among stayers, switchers, and heavy switchers, companies should not only recognize the heterogeneity of their customer base, but also target their marketing efforts accordingly.

This study is one of the few identifying groups of customers perception’s toward service providers. It also complements previous research by splitting them intro three different groups and by analyzing their behaviors across a set of previously unexamined marketing variables.

This paper seeks to describe an approach to mitigate the unsoluble malicious host problem.

By using obfuscation as a component of communication patterns and their switching in an environment of cooperating agents the malicious host can be detected and the attacked agents can be deleted.

Finds that the information about the detected malicious host can be used further, e.g. to prevent another mobile agent from visiting this host.

This paper will be helpful to people involved in information management and computer security issues.

The purpose of this paper is to investigate the time-varying finite-time formation tracking control problem for multiple unmanned aerial vehicle systems under switching topologies, where the states of the unmanned aerial vehicles need to form desired time-varying formations while tracking the trajectory of the virtual leader in finite time under jointly connected topologies.

A consensus-based formation control protocol is constructed to achieve the desired formation. In this paper, the time-varying formation is specified by a piecewise continuously differentiable vector, while the finite-time convergence is guaranteed by utilizing a non-linear function. Based on the graph theory, the finite-time stability of the close-loop system with the proposed control protocol under jointly connected topologies is proven by applying LaSalle’s invariance principle and the theory of homogeneity with dilation.

The effectiveness of the proposed protocol is verified by numerical simulations. Consequently, the proposed protocol can successfully achieve the predefined time-varying formation in finite time under jointly connected topologies while tracking the trajectory generated by the leader.

This paper proposes a solution to simultaneously solve the control problems of time-varying formation tracking, finite-time convergence, and switching topologies.

This paper presents a routing method for two dimensional transputer arrays particularly designed for parallel non‐linear and dynamic finite element analysis. Some general routing strategies with their strengths and weaknesses are discussed. The need for problem specific routing algorithms in transputer systems is considered and the communication requirements for parallel finite element analysis described. From the communication requirements the design parameters for the routing method are specified and the architectural design of the Router presented. An example of the use of the Router in the parallel non‐linear finite element analysis is given and the robustness of the routing methodology is illustrated by using arbitrary mappings of finite element subdomains distributed over a transputer array.

The purpose of this paper is to provide an understanding of process improvement team member perceptions regarding the effectiveness of asynchronous e‐collaboration.

A field‐based, two‐phase canonical action research study was conducted at two different sites. Data were obtained from observations and interviews of all team members. Media synchronicity theory was utilized to hypothesize the interplay of media capabilities, task communication processes, and team functions.

Eight primarily virtual teams solved complex problems and provided feedback on the effectiveness of various communications media. The results support media synchronicity theory.

Media synchronicity theory provides an alternative explanation for studies both supporting and contradicting media richness theory. The teams in this study were newly formed. Further investigation of established teams and other contexts is warranted.

For complex problem‐solving tasks performed by newly formed teams, communications media with low synchronicity (e.g. listserv, e‐mail, bulletin board) may be appropriate for conveyance of information; whereas media with high synchronicity (e.g. face‐to‐face, telephone) may be more desirable for convergence on shared meaning.

As geographic, temporal, and cost constraints move organizations toward virtual team work for increasingly complex tasks, research is warranted on effective utilization of available communication technology for solving business problems without face‐to‐face communication. This research paper examines the issue through an emerging theoretical lens, media synchronicity theory, and suggests a new proposition.

This conceptual paper aims at developing a customer-centric marketing communications approach that takes the starting point in the customer ecosystem.

After a critical analysis of existing marketing communications and integrated marketing communication (IMC) approaches, a customer-driven view of marketing communications is developed using recent developments in relationship communication, customer-dominant logic and the notion of customer value formation as value-in-use.

A customer-integrated marketing communication (CIMC) approach centred on a communication-in-use concept is conceptually developed and introduced. The analysis results in a CIMC model, where a customer in his or her individual ecosystem, based on integration of a set of messages from different sources, makes sense of the many messages he or she is exposed to.

The paper presents a customer-driven perspective on marketing communication and IMC. The analysis is conceptual and should trigger future empirical grounding. It indicates the need for a change in mindset in research.

CIMC requires a turnaround in the mindset that steers how companies and their marketers communicate with customers. The CIMC model provides guidelines for planning marketing communication.

The customer-driven communication-in-use concept and the CIMC model challenge traditional inside-out approaches to planning and implementing marketing communication.

Past research has suggested the influence of family‐oriented collectivistic culture on the behavior and performance of traditional Chinese manufacturing firms. However, insufficient empirical research has been conducted to empirically test the influence. More importantly, insufficient research has been conducted to test how the collectivistic culture in Chinese societies would affect the performance of manufacturing firms. This paper addresses these issues by comparing the behaviors and performance of two groups of firms in China, i.e., investment from overseas Chinese firms and investment from non‐Chinese Western firms, in one of China's fast‐growing manufacturing industries. Interesting differences are found between the overseas Chinese firms and those from other foreign countries. The findings support the influence of societal culture on firms' behavior and performance, but do not support the predictions on performance based on the arguments of cultural distance. This paper concludes with a discussion on implications of the findings for both researchers and practitioners.
