An improved Huffman coding with encryption for Radio Data System (RDS) for smart transportation

As the development of Radio Data System (RDS) technology and its applications are getting more and more attention and promotion, people concern their personal privacy and communication efficiency, and therefore compression and encryption technologies are being more important for transferring RDS data. Unlike most of the current approaches which contain two stages, compression and encryption, we proposed a new algorithm called Swapped Huffman Table (SHT) based on Huffman algorithm to realise compression and encryption in a single process. In this paper, a good performance for both compression and encryption is obtained and a possible application of RDS with the proposed algorithm in smart transportation is illustrated.     

Economic policy uncertainty spillovers in small open economies: The case of Hong Kong

This paper studies the extent to which economic policy uncertainty shocks in major economies affect real economic activity in small open economies. We use Hong Kong as a case study. Following Baker, Bloom and Davis (2016), we construct a newspaper‐based economic policy uncertainty index for Hong Kong for the period 1998 to 2016. We estimate international spillovers of uncertainty and find large spillovers of uncertainty from major economies to Hong Kong. Furthermore, using a structural vector autoregressive approach, we show that a rise in domestic economic policy uncertainty leads to tight financial conditions, and lower investment and vacancy posting, dampening domestic output growth.     

State-of-the-art social customer relationship management

The rise of social media challenges the traditional notion of customer relationship management (CRM) and has led to the emergence of social CRM. This study collected and content-analyzed recent literature along the intersection between social media and CRM, to present an overview of the social CRM research in tourism and hospitality. Findings indicate that most studies focus on the context of hotel and restaurant. These studies lack a solid theoretical underpinning and tend to adopt qualitative research methods. Five research themes are identified from supply-focused research, while two themes are observed from demand-focused research. Overall, uneven attention has been paid by researchers in the field, with more emphasis on supply than on demand sides. According to the findings of the literature review, a conceptual framework and a research agenda are presented. Theoretical and practical implications to the tourism and hospitality industry are also discussed.     

Quality investing in Asian stock markets

We examine two quality investing strategies using gross profitability (GP) or FSCORE, respectively, over the period of 2000–2016 in Hong Kong, Japan, Korea, Singapore and Taiwan stock markets. We find that the high-quality stocks generally earn positive returns in these markets. Both FSCORE and GP are significantly positively associated with subsequent stock returns in the cross-sectional regressions. We also find that financial institutions as sophisticated investor concern about stock quality. The actively managed institutions buy significantly more high-quality stocks than low-quality stocks in each of five Asian markets. The trading pattern is not significant in passively managed institutions.     

Integrating Behavioural and Branding Perspectives to Maximize Green Brand Equity: A Holistic Approach

The aim of this study is to expand the existing understanding of green consumers' behaviour by proposing and testing an integrated conceptual model that explores the influence of consumers' personal concerns for the environment and general attitudes towards green products on brand‐related knowledge structures (image and associations) and relationship preferences (trust and brand equity) for green brands. A questionnaire‐based survey method was used to collect data using convenience sampling. One hundred and ninety‐nine usable responses were obtained. A structural equation modelling procedure was used to test the proposed hypotheses. The results confirmed that a positive relationship exists between consumer concern for environmental values and general attitudes towards green products. Both these constructs influence consumers' knowledge structure of a green brand (image and associations). Furthermore, a strong relationship exists between consumers' knowledge structure (image and associations) and their relational preference (trust and brand equity) with green brands. These findings are important for business strategy formulation by providing empirical support for the idea that a firm should invest its resources not only to project its environmentally friendly brands but also to build consumers' concern for environmental values and their attitude towards green products.

Behavioral insurance and economic theory: A literature review

Decisions to purchase insurance should be a perfect place to see economic theory at work in general, and behavioral economics at work in particular. We have well‐developed theories of the demand for, and welfare evaluation of, insurance products. These theories extend relatively easily to the insights of behavioral economics. Unfortunately, the empirical literature has not maintained this tight connection. In fact, much of the empirical literature illustrates the dangers of the modern passion with agnostic economics: avoiding theory at all costs to focus on “what works.” We identify these dangers and the implications in the literature.     

NEGOTIATED BLOCK TRADE AND REBUILDING OF TRUST

We investigate the impact of corporate governance on customers' trust using a dynamic model of experience-goods firm. In the optimal equilibrium, customers' trust in the firm is linked to its behavior in the market for corporate control, so that the controlling shareholder has incentives to ensure high product quality while noncontrolling shareholders' interests are protected. Following a trust-damaging event, turnover of the controlling share block restores customers' trust and enhances total shareholder value. Our analysis identifies an endogenous cost of corporate control, offers implications for the control premium, and provides a novel rationale for the separation of ownership and control.     

A semantic similarity analysis of Internet of Things

ABSTRACT

Internet of Things (IoT) has gradually become one of the most popular topics among both academia and industry, and it is considered as a crucial part of future Internet. However, very few objective and systematic review was conducted to address high-value articles and summarize the intellectual components from journals for examination and identification of the intellectual core and structure of IoT. Therefore, this study conducted a co-citation analysis for IoT by using 68 high-value articles retrieved within 1457 source papers from Web of Science online database. By using factor analysis, ten critical factors were identified, which includes (1) frameworks and challenges of IoT; (2) current situation of IoT in different applications; (3) interactions of IoT; (4) security issues of IoT; (5) application domains of IoT; (6) data management of IoT; (7) IoT in product lifecycle management; (8) enabling technologies of IoT; (9) IoT in smart cities; (10) IoT in recommender systems. Hierarchical Custer Analysis and Multidimensional Scaling were used to graphically illustrate the intellectual elements of IoT. In the current findings, fundamental elements of IoT including architectural framework, enabling technologies, network communication, data management, and IoT interactions were discussed with a series of challenges for wider and deeper IoT applications.
