Weakly-constrained codes for suppression of patterning effects in digital communications

We propose weakly-constrained stream and block codes with tunable pattern-dependent statistics and demonstrate that the block code capacity at large block sizes is close to the the prediction obtained from a simple Markov model published earlier. We demonstrate the feasibility of the code by presenting original encoding and decoding algorithms with a complexity log-linear in the block size and with modest table memory requirements. We also show that when such codes are used for mitigation of patterning effects in optical fibre communications, a gain of about 0.5dB is possible under realistic conditions, at the expense of small redundancy (≈10%). © 2010 IEEE

Self-affirmation before exposure to health communications promotes intentions and health behavior change by increasing anticipated regret

Health-risk information can elicit negative emotions like anticipated regret that may positively affect health persuasion. The beneficial impact of such emotions is undermined when target audiences respond defensively to the threatening information. We tested whether self-affirming (reflecting on cherished attributes) before message exposure can be used as strategy to enhance the experience of anticipated regret. Women were self-affirmed or not before exposure to a message promoting fruit and vegetable consumption. Self-affirmation increased anticipated regret and intentions reported following message exposure and consumption in the week after the intervention; regret mediated the affirmation effect on intentions. Moreover, results suggest that anticipated regret and intentions are serial mediators linking self-affirmation and behavior. By demonstrating the mediating role of anticipated regret, we provide insights into how self-affirmation may promote healthy intentions and behavior following health message exposure. Self-affirmation techniques could thus potentially be used to increase the effectiveness of health communication efforts.

Measuring QoS in an aeronautical opportunistic network architecture with limited access to a satellite communications backhaul

We measure quality of service (QoS) in a wireless network architecture of transoceanic aircraft. A distinguishing characteristic of the network scheme we analyze is that it mixes the concept of Delay Tolerant Networking (DTN) through the exploitation of opportunistic contacts, together with direct satellite access in a limited number of the nodes. We provide a graph sparsification technique for deriving a network model that satisfies the key properties of a real aeronautical opportunistic network while enabling scalable simulation. This reduced model allows us to analyze the impact regarding QoS of introducing Internet-like traffic in the form of outgoing data from passengers. Promoting QoS in DTNs is usually really challenging due to their long delays and scarce resources. The availability of satellite communication links offers a chance to provide an improved degree of service regarding a pure opportunistic approach, and therefore it needs to be properly measured and quantified. Our analysis focuses on several QoS indicators such as delivery time, delivery ratio, and bandwidth allocation fairness. Obtained results show significant improvements in all metric indicators regarding QoS, not usually achievable on the field of DTNs.

Significant Attributes and Challenges Related to Cross-Functional Team Communications

Purpose The purpose of the research work is to investigate the importance of the communication in the cross-functional teams and in what which communicational tools provide better convenience of communication in cross-functional team members. Methodology An empirical study including the data collection from the interviews conducted from the participants working in cross-functional teams. Qualitative approach has been adopted to understand the communicational attributes in the cross-functional teams. For the analysis both deductive and abductive approach has been used. With the help of theoretical framework and empirical data, conclusions drown for better understanding of the concept. Findings The author has divided the search in two main segments, communicational effects on cross-functional team performance and effectiveness of particular communicational tools used by team members and team leaders. Empirical findings shows that without proper communication, cross-functional team are less tend to perform well to achieve set goals as well as face to face communications are more effective than other communicational tools.  Research limitations The research work is limited to Scandinavian countries. Organizational communicational structures are not studied due to time factor. Other limitation of this research work is effect of cultural differences on communication. Implications The research work provides deep understanding of the different communicational effects on cross-functional team performance. The choice of communicational tool and proportional importance for the team members will help managers while selecting the tools of communication with the team members. Originality / value During the literature studies, author determined that there is potential of research for the communicational tools used in cross-functional team communications. The social media is taking over the traditional communicational tools which provide value for findings. 

Batch Verification of Validity of Bids in Homomorphic E-auction

Bid opening in e-auction is efficient when a homomorphic secret sharing function is employed to seal the bids and homomorphic secret reconstruction is employed to open the bids. However, this high efficiency is based on an assumption: the bids are valid (e.g., within a special range). An undetected invalid bid can compromise correctness and fairness of the auction. Unfortunately, validity verification of the bids is ignored in the auction schemes employing homomorphic secret sharing (called homomorphic auction in this paper). In this paper, an attack against the homomorphic auction in the absence of bid validity check is presented and a necessary bid validity check mechanism is proposed. Then a batch cryptographic technique is introduced and applied to improve the efficiency of bid validity check.

Visitor Relationship Management (VRM) - Repeat Visitation Opportunities for Destination Marketing Organisations

In competitive tourism markets the consumer-traveller is spoilt by choice of available destinations. Successfully differentiating a destination and getting noticed at decision time is arguably the focus of activities by destination marketing organisations (DMOs). In pursuit of differentiation, three emergent themes in the marketing literature during the past decade have been branding, integrated marketing communications (IMC), and customer relationship management (CRM) a fundamental goal of each being stimulating customer loyalty. However there has been little attention given to destination loyalty in the tourism literature. The purpose of this paper is to report an exploratory investigation of visitor relationship management (VRM) by DMOs. Based on interviews with the management of 11 regional tourism organisations (RTO) in Queensland, Australia, the opportunities for, and immediate challenges of, VRM are discussed. While each RTO recognised the potential for VRM, none had yet been able to develop a formal approach to engage in meaningful dialogue with previous visitors from their largest market.

Selecting an IMC Career: Influences, Choices and Destinations

Integrated marketing communication incorporates both customer and non-customer stakeholder groups. While the literature commonly refers to this distinction as marketing communication and corporate communication, respectively, and practitioners accept the need for these roles, this study aims to explore the student perspective. US-based research suggests that students are more interested in marketing communication activities such as promotion that target customer stakeholders, and less interested in corporate communication activities that target non-customer stakeholders including employees, investors, and government (Bowen, 2003). The findings of this study match its US counterpart, and present implications for both the education and practice of marketing communication
